Technical Field

[1] The present disclosure relates to a handheld drying device for the human body. Background

[2] People who are less mobile, such as those with injuries and ailments, often have difficulties drying parts of their bodies after engaging in activities such as bathing and showering. In particular, they often have difficulties using a towel to dry harder to reach places, such as between the toes, back of the knees, underarms or lower back. Thus, the person may not be able to dry themselves completely, which can cause health and hygiene issues.

[3] A possible way to address this issue is for a care person to assist the less-mobile person to dry themselves. However, this can have a significant impact on the person's independence. Therefore, it would be desirable to provide a device which can dry the human body effectively whilst overcoming the above-mentioned issues.

[4] Any discussion of documents, acts, materials, devices, articles or the like which has been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present disclosure as it existed before the priority date of each claim of this application.

[5] Throughout this specification the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps. Summary

[6] A handheld drying device for the human body comprising: a main body having an airflow source; an outlet head removably attached to the main body; and a permeable layer arranged on the outlet head, wherein the airflow source is arranged to pass airflow through the outlet head and permeable layer.

[7] In this way, a user can arrange the outlet head in the proximity of the target area for drying.

[8] The provision of the permeable layer may assist in drying the target area more effectively by absorbing moisture when in contact with the target area. The airflow may assist drying of the target area and the permeable layer which may allow more effective drying.

[9] In some circumstances, the device may be used as a supplementary means to dry the human body in conjunction with using towels. For example, large surfaces and easy to reach places of the body may be patted dry with towels and the device used for the smaller and/or harder to reach places of the body. In other circumstances, the device may be used as an alternative to towels. Therefore the device may reduce the use of towels to dry the human body. This may reduce the cupboard space required to store towels in bathrooms, households, hospitals, nursing homes, etc.

[10] The handheld drying device may further comprise an elbow to redirect airflow from the main body to the outlet head.

[11] The elbow may be selectively adjustable to reconfigure the outlet head relative to the main body, to adjust the redirected airflow from the main body to the outlet head.

[12] The elbow may include a resilient portion to allow the outlet head to move relative to the main body as a result of an external force transmitted to the outlet head.

[13] The elbow may include a substantially right angle section to redirect airflow substantially right angle from the main body to the outlet head. [14] In the handheld drying device the outlet head may comprise a diffuser including a plurality of apertures.

[15] The plurality of apertures may include a plurality of slots extending radially from a centre of the diffuser.

[16] The plurality of apertures may include a plurality of arcuate slots, the slots extending around a centre of the diffuser.

[17] In the handheld drying device, the outlet head may further comprise a plurality of support members, wherein the plurality of support members extend towards the permeable layer.

[18] In the handheld drying device, the outlet head may further comprise: a diffuser guide including a resilient portion; and a diffuser base to receive the diffuser guide, wherein the diffuser is mounted to the diffuser guide such that the diffuser is resiliently movable relative to the diffuser base as a result of an external force transmitted to the diffuser.

[19] In the hand held drying device, the outlet head may further comprise: a diffuser guide to receive the diffuser; and a diffuser base to receive the diffuser guide, wherein the diffuser is selectively mountable to the diffuser guide, and/or the diffuser guide is selectively mountable to the diffuser base, such that the direction and/or volume of airflow through the plurality of apertures are selectively adjusted.

[20] In the handheld drying device, the permeable layer may be removably attached to the diffuser.

[21] In one alternative of the handheld drying device the permeable layer may be fixed to the diffuser.

[22] In the handheld drying device, the permeable layer may comprise a hydrophilic material.

[23] In the handheld drying, the permeable layer may comprise a hydrophobic material. [24] In the handheld drying device, the permeable layer is a fabric.

[25] In the handheld drying device, the permeable layer may be profiled with variable thickness including at least one thick portion and at least one thin portion such that airflow through the thin portion is greater than the thick portion.

[26] The handheld drying device may further comprise an air permeable shield, wherein the air permeable shield includes a hydrophobic material to hinder passage of liquid water, wherein the air permeable shield is locate at an air intake to the airflow source and/or the exhaust from the airflow source.

[27] The handheld drying device may further comprise a heat source arranged to heat the airflow.

[28] The handheld drying device may further comprise a controller to: control the airflow source to control a speed of the airflow from the airflow source; and/or control the heat source to control the temperature of the airflow.

[29] The handheld drying device may further comprise a diffuser that is pivotally mounted, on one or more axes, relative to the main body such that in use the diffuser is tiltable to follow one or more contours of the human body.

[30] A diffuser for use in the handheld drying device described above.

[31] There is also disclosed a handheld drying device for the human body, comprising: an air flow source; an absorbent layer arranged on an outlet head; and an agitator arranged to actively agitate the outlet head; wherein the air flow source is arranged to pass air flow through the outlet head. In this way, a user can arrange the outlet head in the proximity of the target area for drying.

[32] The provision of the absorbent layer may assist in drying the target area more effectively by absorbing moisture when in contact with the target area. The agitation of the outlet may also cause agitation of the absorbent layer which may cause the absorbent layer to absorb moisture more effectively. [33] Agitation of the outlet head may help to diffuse the air flow over the target area. This may help to avoid air flow from being focussed too intensely on the target area, which could cause discomfort when the air flow is hot or highly pressurised. In some cases, the less- mobile person may have difficulty in directing the outlet over the entire target area for drying. The agitation of the outlet head may assist in spreading the air flow and the absorbent layer around the target area, which may be advantageous where the less-mobile person lacks the dexterity to achieve this manually.

[34] The agitator may be arranged to agitate at least a part of the outlet head relative to a handle of the device.

[35] The air flow source may be arranged to pass air flow through the absorbent layer. Thus the air flow can assist in drying the absorbent material, which may allow it to absorb a greater quantity of moisture during use.

[36] The absorbent layer may comprise at least one aperture through which the air flow source is arranged to pass air flow. In this way, air flow can be maximised through at least one localised area of the outlet head.

[37] The absorbent layer may comprise a single aperture through which the air flow source is arranged to pass air flow. The absorbent layer may comprise a plurality of apertures through which the air flow source is arranged to pass air flow.

[38] The absorbent layer is removable from the outlet head. In this way, it is possible to thoroughly cleanse the absorbent layer between uses. In addition, the absorbent layer may be replaced from time to time. This ensures that the drying device remains clean which may assist in avoiding health issues.

[39] The outlet head may comprise a plurality of support members arranged to support the absorbent layer. Thus it is possible to maximise the surface area of the absorbent layer in contact with the target area.

[40] The agitator may be arranged to rotate the outlet head and/or the absorbent layer about a first axis. [41] The first axis, about which the outlet head and/or the absorbent layer is arranged to rotate, may be arranged substantially parallel with a main axis of the elongate body.

Alternatively the first axis, about which the outlet head and/or the absorbent layer is arranged to rotate, may be arranged substantially perpendicular to the main axis of the elongate body.

[42] In one alternative, the agitator may be arranged to vibrate the outlet head and/or the absorbent layer.

[43] The drying device may comprise an elongate body wherein the outlet head is located towards a first end of the elongate body. The elongate body may help to direct the outlet towards hard to reach areas of the body for drying.

[44] The drying device may comprise a handle. The handle may be located towards a second end of the elongate body, distal to the first end of the elongate body. The drying device may comprise an extendable portion located between the handle and the outlet head. The extendable portion may be retractable.

[45] The drying device may comprise a heat source arranged to heat the air flow. The heat source may be arranged between the air flow source and the outlet head.

[46] The outlet head may comprise a first removable head. The first removable head may be replaceable with a removable washing head. The washing head may comprise a brush. Thus, the drying device may be adapted to function as a washing device.

[47] The first removable head may be replaceable with a removable applicator head. The applicator head may comprise an applicator surface for applying creams and/or ointments. Thus, the drying device may be adapted to function as an applicator for creams and ointments. The applicator surface may comprise a sponge and/or a soft plastic material.

[48] There is also disclosed a multi -function handheld device for the human body, comprising: an air flow source; at least one removable outlet head; and an agitator. The multifunction handheld device may be configured in a drying mode. In the drying mode, the at least one removable outlet head comprises a first removable head, and an absorbent layer arranged on a first removable head. The agitator may be arranged to actively agitate the first removable head and the air flow source arranged to pass air flow through the first removable head.

[49] The multi-function handheld device may be configured in a washing mode. In the washing mode, the at least one removable outlet head comprises a removable washing head, and the agitator is arranged to actively agitate the removable washing head.

[50] The multi -function handheld device may be configured in an applicator mode. In the applicator mode, the at least one removable outlet head comprises a removable applicator head comprising an applicator surface for applying creams and/or ointments. The agitator may be arranged to actively agitate the removable applicator head.

[51] There is also disclosed a kit of parts for use with a handheld grooming device comprising an air flow source and an agitator. The kit may include: an absorbent layer; and a first removable head to receive the absorbent layer. The kit may be arranged with the handheld grooming device in a drying mode where: the absorbent layer is arranged on the first removable head; the agitator is arranged to actively agitate the first removable head; and the air flow source is arranged to pass air flow through the first removable head.

[52] The kit of parts may also include a removable washing head comprising a brush. The kit may be arranged with the handheld grooming device in a washing mode where the agitator is arranged to actively agitate the removable washing head. This may be used to assist scrubbing of the body whilst bathing or showering.

[53] The kit of parts may also include a removable applicator head comprising an applicator surface for applying creams and/or ointments. The kit may be arranged with the handheld grooming device in an applicator mode where the agitator is arranged to actively agitate the removable applicator head. This may be used to assist a user applying creams, ointment or medicaments to the body.

[54] In some circumstances, the device may be used as a supplementary means to dry the human body in conjunction with using towels. For example, large surfaces and easy to reach places of the body may be patted dry with towels and the device used for the smaller and/or harder to reach places of the body. In other circumstances, the device may be used as an alternative to towels. Therefore the device may reduce the use of towels to dry the human body. This may reduce the cupboard space required to store towels in bathrooms, households, hospitals, nursing homes, etc.

[78] Referring to Figures 1 to 4, there is provided a handheld drying device 1 including a main body 2 having an airflow source 12, an outlet head 7removably attached to the main body 2, and a permeable layer 8 arranged on the outlet head 7. The airflow source 12 is arranged to pass airflow through the outlet head 7 and the permeable layer 8. [79] The device 1 has a circular upper section 5 located towards a first end of the device 1 and a handle 3 located towards a second end of the device 1. As illustrated, the second end of the device 1 is distal to the first end of the device 1.

[80] The upper section 5 includes the outlet head 7 through which airflow passes. An elbow 14 is provided to redirect airflow between the main body 2 and the outlet head 7. The outlet head 7 is covered by the permeable layer 8. In one example, the permeable layer 8 is made from an absorbent material. Airflow 16 is generated by the airflow source 12 within the device 1 which is powered by a power cable 11. The handle 3 has a control interface 4 on one of its sides which can be used to control the device 1.

[81] In use, a user of the device 1 grips the handle 3 and positions the upper section 5 so that airflow from the outlet head 7 is directed onto a target area of the user's body for drying. This may allow the user to dry hard to reach parts of the body.

[82] The user can move the upper section 5, using the handle 3, so that the permeable layer 8 contacts with the target area of the user's body. The permeable layer 8 thus aids in the drying process.

[83] In use, air is blown through the outlet head 7 and through the permeable layer 8 of absorbent material. This helps to dry the target area more quickly. In addition, the airflow 16 through the permeable layer helps to dry the layer, in order to help to avoid the layer from becoming saturated with moisture.

[84] Referring to Figure 5, the airflow source 12 comprises a fan 13 which is powered by an electric motor 15. As is illustrated by the arrows in Figure 5, air enters the device 1 through an inlet 17, and the airflow 16 generated by the fan 13 passes through a channel 19 and exits the device 1 through the outlet head 7. In doing so, the airflow passes through the permeable layer 8. There is a heating element 20 positioned within the channel 19 which can be activated to heat the air in order to assist in the drying process. It is to be appreciated that in some alternatives the heating elements may be positioned between the inlet 17 and the airflow source 12. [85] One or more airflow air permeable shields 32, 38 may be provided to hinder passage of liquid water to parts of the dryer 1. A first permeable shield 32 hinders liquid water from entering through the inlet 17 and interfering with electrical components such as the motor 15 and heating element 20. A second permeable shield 38 is placed in the exhaust from the airflow source 12 and similarly hinders liquid water from entering through the channel 19 and interfering with electrical components. The permeable shields 32, 38 may include

hydrophobic material.

[86] The control interface 4 on the handle 3 of the device 1 can be operated by a user in order to control the airflow source 12 and the heating element 20. Using the control interface 4, the user is able to control the intensity of the airflow provided by the airflow source 12, and/or the amount of heat provided by the heating element 20. The control interface 4 could be used to turn off/on the airflow source 12, and the heating element 20. For example, the user may decide to activate the airflow source 12 without activating the heating element 20.

[87] The user may use the control interface 4 to control the heating element 20 in order to select an output temperature for the airflow. The output temperature may be anywhere between 20°C and 60°C. There may be a 'low' setting for the heating element 20 where the output temperature of the airflow is between 20°C and 30°C. There may be a 'medium' setting for the heating element 20 where the output temperature of the airflow is between 30°C and 40°C. There may be a 'high' setting for the heating element 20 where the output temperature of the airflow is between 40°C and 60°C. It is to be appreciated that other temperature settings and temperature ranges may be implemented including an infinitely variable temperature control between zero heating and maximum heating.

[88] The user may use the control interface 4 to control the airflow source 12 in order to select the intensity of the airflow 16. There may be a 'low', 'medium' and 'high' setting for the airflow source 12. Similarly to temperature, the fan may also be controlled by an infinitely variable controller from zero to maximum.

The outlet head 7

[89] Features of the outlet head 7 will now be described in detail. The elbow 14

[90] In the example of figure 1 and 6, the drying device 1 has an elbow 14 that redirects airflow 16 from the main body 2 by a right angle towards the permeable layer 8. In this example, the elbow 14 includes an inlet 51 that is fluidly connected to the main body 2 to receive the airflow 16. The inlet 51 may include threading, a bayonet fitting or other connection and attachment means to allow the elbow 14 to be removably attached to the main body 2. In some examples, the inlet 51 may be attached to the main body 2 by push fit. By allowing the elbow 14 to be removable attached to the main body 2, this may facilitate ease of cleaning and maintenance of the drying device 1. For example, it may be desirable to clean interior of the elbow 14, and removing the elbow 14 may allow the elbow to be washed without the risk of damaging electrical components in the main body 2 of the drying device 1.

[91] The elbow 14 in this example has a right angle (i.e. 90 degrees) although it is to be appreciated that other angles may be used according to the user's preference and dimensions. For example, the elbow may redirect airflow to between 120 to 90 degrees, 90 to 70 degrees, 70 to 45 degrees, 45 to 30 degrees.

[92] In some examples, the elbow 14 may be selectively adjustable to reconfigure the outlet head 7 (in particular the direction of the permeable layer 8) relative to the main body 2 to adjust the redirected airflow from the main body 2 to the outlet head 7 and permeable layer 8. This is illustrated in figures 7(a) and 7(b) that includes an elbow having a first elbow section 53 and a second elbow section 55, where the first and second sections 53, 55 are pivotally connected to one another by a pivot 57. It is to be appreciated that in other examples, the elbow 14 may be made of a flexible material so that the elbow 14 can be selectively adjusted. Alternatively the elbow may be made of discrete components much like a spine so that the angle can be varied between each of the components.

[93] In yet another example, the elbow 14 may include a resilient portion to allow the outlet head 7 to move relative to the main body 2 as a result of an external force transmitted to the outlet head 7. This may allow the outlet head 7 (including the permeable layer 8) to be used such that there is contact and pressure against the human body surface whilst at the same time allowing some conformity to the body surface. By having a resilient portion that is elastic, this may allow the device 1 to absorb excessive pressure that could be applied by a user.

Diffuser base 61

[94] In the example of figures 1 to 6, the elbow 14 is fluidly connected with the circular upper section 5 that forms the diffuser base 61. The diffuser base 61 receives other parts of the outlet head 7, which in this example includes a diffuser guide 63 that in turn receives a diffuser 65 and the permeable layer 8.

[95] The diffuser base 61 includes a central passage 67 to allow the redirected airflow 16 to pass through. The central passage 67 may include a venturi to widen the airflow 16 from the elbow 14 to the diffuser 65. This may include decreasing velocity and/or pressure of the airflow.

[96] The diffuser base 61 also includes connectors to the diffuser guide 63. In this example, it includes an internal ledge 69 to abut with the diffuser guide 63 and apertures 71 to receive connector projections 72 of the diffuser guide 63.

[97] In the example shown in figure 1 the diffuser base 61 is integrally formed with the elbow 14. However, it is to be appreciated that in other examples, the elbow 14 may be separately formed to the diffuser base 61 and that they can be assembled and disassembled to each other for ease of storage, reconfiguration, maintenance and cleaning, etc. Similarly, diffuser guide and diffuser may be integrated, or diffuser base and diffuser guide may be integrated, or other combinations of integrating the diffuser, diffuser guide and diffuser base.

Diffuser guide 63

[98] The diffuser guide 63 provides an interface between the diffuser base 61 and the diffuser 65. The diffuser guide 63 includes a diffuser guide aperture 73 to allow the airflow to pass through from the diffuser base 61 to the diffuser 65. The diffuser guide aperture 73 may be a cylindrical bore or may include a venturi.

[99] The diffuser guide 63 includes connectors or other means for allowing attachment with the diffuser 65. In figure 1, the diffuser guide 63 includes screw apertures 75 to allow a screw (or other type of fastener) to pass through such that the diffuser guide 63 can be attached to the diffuser 65.

[100] The diffuser guide 63 also includes secondary apertures 77. The secondary apertures 77 include a plurality of arcuate slots that follow the periphery of the circular diffuser guide 63. In some examples, these apertures may not be symmetrical, in which case the diffuser guide 63 may be manually rotated to a user's preference. The secondary apertures 77 allow some airflow to pass from the diffuser base 61 to the surrounding atmosphere. The secondary apertures 77 may help to avoid excessive build up in pressure, should the permeable layer 8 become saturated with moisture. The increased air flow may advantageously provide a drying mechanism similar to an air knife.

[101] In some examples the diffuser guide 63 includes a resilient portion such that the diffuser 65 is resiliently movable relative to the diffuser base 61 as a result of external force transmitted to the diffuser 65. This allows the diffuser 65 some freedom to move and conform with the surface of the human body. The diffuser 65 may also be spring loaded so that it always returns to a starting position. For example, the diffuser guide 63 may include one or more pivots, on one or more axes, so that the attached diffuser 65 is pivotally mounted to the main body 2. In turn, a resilient member, such as a leaf spring, coil spring or compressible medium may bias the diffuser 65 to a starting position. During user, this allows the diffuser 65 to tilt and follow one or more contours of the human body.

[102] In some examples the diffuser guide 63 may have features that allow the diffuser 65 to be selectively mountable to the diffuser guide 63, and/or the diffuser guide 63 to be selectively mountable to the diffuser base 61, such that the direction and volume of airflow through the apertures 79 of the diffuser 65are selectively adjusted. For example, the diffuser guide 63 may include asymmetric interfaces between the diffuser base 61 and/or diffuser 65, asymmetric internal surfaces, or asymmetric diffuser guide aperture 73 such that the airflow 16 through the diffuser guide 63 to the diffuser 65 is not evenly distributed to the diffuser 65. For example, one semi-circular side of the diffuser 65 may receive more airflow 16 than the other. Furthermore, the diffuser guide 63 may be connectable to the diffuser base 61 in multiple orientations (such multiple angular orientations) so that the resultant direction and/or orientation of airflow to the diffuser 65 can be adjusted. [103] It is to be appreciated in other alternatives the diffuser base 61 and/or diffuser 65 may have features that independently (or with other components) allow selective adjustment of the direction and/or volume of airflow 16. For example, the connections between the components may be adjustable to allow selectively different configurations.

The diffuser 61

[104] The diffuser 65 operates to allow the airflow 16 to pass through whilst supporting the permeable layer 8. This may be achieved with a diffuser 65 that includes a plurality of apertures 79, where the airflow 16 passes through the apertures 79 and to the permeable layer 8.

[105] Different configurations of the diffuser 61 will be described below.

First diffuser type

[106] Figures 8 and 9 illustrate a first diffuser type. The diffuser 65' includes a

substantially circular body having a plurality of apertures 79 for the airflow 16 to pass through. At the side facing the diffuser guide 63, there is a plurality of bosses to receive screws (or other fasteners) to attach the diffuser 65' to the diffuser guide 63.

[107] The side facing the permeable layer 8 includes a plurality of support members 23 that extend towards the permeable layer 8. The support members 23 are arranged upstanding on the surface of the outlet head 7 providing a support surface for the permeable layer 8. This support surface helps to prevent the absorbent material 8 from flexing inwards away from the target area. It may also provide a massaging effect. In the illustrated example the surface of the outlet head 7 (from which the support members 23 are arranged on) is substantially flat. However it is to be appreciated that in other examples the surface of the outlet head 7 may be undulating.

Second diffuser type

[108] Figures 10 and 11 illustrate a second diffuser type. The diffuser 65" includes a substantially circular body having a plurality of apertures including a central aperture 79' and a plurality of arcuate slots 79" around the central aperture 79' . At the side facing the diffuser guide 63, there are a plurality of apertures 82 that least to bosses 81 to receive screws (or other fasteners) to attach the diffuser 65" to the diffuser guide 63.

[109] The central aperture 79' has a venturi (or funnel) to guide part of the airflow 16 to a central portion of the permeable layer 8. In some examples, this may be advantageous as this may correspond to the target area for drying the human body.

[110] At the side of the diffuser 65" facing the permeable layer 8, there are a plurality of support members 83 extending radially outwards from the central aperture 79'. The support members provide support to the permeable layer 8 as shown in figures 11.

Third diffuser type

[111] Figures 12 and 13 illustrate a third diffuser type. The diffuser 65" includes a substantially circular body having a plurality of apertures 79"', in the form of slots, that extend radially from a centre portion 80 of the circular body.

[112] The centre portion 80 at the side facing the permeable layer 8 has a solid surface to support the permeable layer 8. This may be advantageous in providing additional support to the permeable layer 8. Furthermore, the solid surface of the centre portion 80 may assist diffusing and distribution of airflow to other parts of the diffuser 65" ' . Referring to figure 13(c), the airflow 16 through the diffuser guide aperture 73 will need to distribute radially outwards towards the plurality of apertures 79"', since the centre portion of the diffuser 65"' will block the flow path.

[113] The diffuser 65"' may also have supports 23" ' that extend from the circular body towards the permeable layer 8. In one example, the supports follow at least part of the perimeter of the plurality of apertures 79"' .

Fourth diffuser type

[114] Figures 14(a) and 14(b) illustrate a fourth diffuser type. The diffuser 65" " includes a support disc 35 with a top surface upon which a plurality of support members 23 are arranged. The permeable layer 8 covers the support members 23 and is attached to the outer wall of the support disc 35. In this example, the aperture 9 is in the centre of the layer of absorbent material 8.

[115] Each support member 23 is a short prong made from a material such as rubber, metal, silicone, or plastic. There are apertures 34 between the support members 23 through which airflow can pass. The support members 23 assist in maintaining the permeable layer 8 in contact with the target area, by preventing inward flexing, whilst allowing airflow through the material 8.

[116] The support disc 35 comprises a groove 36 in its outer wall into which the edges of the permeable layer 8 can be inserted and held in place. The edges of the permeable layer 8 are adapted to lock into place in the groove 36. In one example, the permeable layer 8 may have an elasticised portion for engagement with the groove 36. The permeable layer 8 can be removed from the support disc 35 for cleaning and then reattached. Alternatively, the permeable layer 8 may be removed from the support disc 35, thrown away and replaced with a fresh layer.

[117] In this example, the permeable layer 8 also includes an aperture 9 through which airflow 16 passes. The aperture 9 can be used to direct a more intense airflow over a localised area. The aperture 9 may also help to avoid excessive build up in pressure, should the absorbent material 8 become saturated with moisture.

[118] The above example diffusers have a substantially circular body. However it is to be appreciated that other body shapes may be suitable, for example rectangular, hexagonal, triangular, or star shaped.

Permeable layer 8

[119] The permeable layer 8 may be made of a material suitable for passing airflow 16 whilst comfortable for contact with the skin of a person. In some examples, the permeable layer 8 is a layer of absorbent material that includes a textile of fibre material. For example, lamb's wool, microfiber or terry towelling may be appropriate. [120] In some examples, the permeable layer 8 includes a layer of fabric. In other examples, the permeable layer may include other permeable material, such as a sponge, open cell foam, etc.

[121] The permeable layer 8 may include a portion with hydrophilic material that increases absorption of liquids to suck liquid off the surface of the skin of the body.

[122] In some examples, the permeable layer 8 may include a portion with hydrophobic material that may assist repelling water. This may include repelling water from one or more parts of the dryer (for example, providing hydrophobic material adjacent the diffuser 65 so that moisture does not flow into the drying). Thus in some examples, the permeable layer 8 may include two layers, a layer with hydrophilic material for contact with the skin of a person which is backed by a hydrophobic layer to prevent, or reduce, moisture penetrating back through apertures 79 of the diffuser 65. Alternatively, a single layer may be made up of both hydrophobic and hydrophilic materials.

[123] In yet some other examples, the permeable layer 8 may include a hydrophobic material for contact with the skin of the user. In these examples, the permeable layer 8 may be useful for wiping off moisture from the skin of the user.

[124] The permeable layer 8 may advantageously be selected from materials that are quick drying. The permeable layer 8 may also include or be coated by a material that is mould resistant.

[125] In some examples, the permeable layer 8 may have uniform thickness. In other examples, the permeable layer 8 may have variable thickness including at least one thick portion and at least one thin portion such that airflow through the thin portion is greater that the thick portion. This may be useful in some applications where it is desirable to have a higher rate of airflow than other parts. In further examples, the thicker portion may absorb more moisture.

[126] In some examples, the permeable layer 8 may be removable from the diffuser 65 such that the permeable layer 8 can be replaced, washed, etc. The permeable layer may be attached to the diffuser 65 by elastics, clips, etc. [127] In other examples, the permeable layer 8 is permanently attached to the diffuser 65. Thus the permeable layer 8 and diffuser 65 may be treated as a replaceable unit. For example, in a hospital setting a dryer may be used by multiple users. The diffuser 65 and permeable layer 8 may therefore be attached, used, and replaced for each patient.

Variations

[128] In the above examples, a diffuser guide 63 is used as an interface between the diffuser base 61 and the diffuser 65. It is to be appreciated that in some variations, one or more of these components may be combined together. For example, the diffuser 65 and diffuser guide 63 may be a single component.

[129] Figure 15 illustrates a variation of the dryer 1. In this example, the handle 3 comprises a power unit 29 at the opposite end of the device 1 to the upper section 5. The power unit 29 comprises a battery which is used to power the device 1. The battery can be charged by a docking station 27 powered by a power cable 25. The device 1 can be docked into the docking station 27 for charging and removed from the docking station 27 for use. The handle 3 comprises a removable cover which provides access to the battery so that it can be replaced. The device 1 may be powered either by a battery or mains power or both.

[130] Preferably, the device 1 is waterproof. The docking station 27 may charge the battery by inductive charging.

[131] In some variations, the drying device 1 includes an extendable section between the handle 3 and the upper section 5. The extendable section can be used to increase the distance between the handle 3, which the user holds, and the outlet head 7, through which airflow 16 passes. The extendable section may also be retracted to decrease the distance between the handle 3 and the outlet head 7. Increasing or decreasing the distance between the handle 3 and the outlet head 7 may allow the user to access harder to reach areas of the body for drying.

[132] The drying device 1 may also have a mounting attached to the top of the upper section 5. The mounting is arranged so that the device 1 can be attached to a wall bracket when storing the device 1. Second example

[133] Referring to Figures 16 and 17, there is provided another example of a handheld drying device 101 comprising an air flow source 112, an outlet head 107, an absorbent layer 108, and an agitator 121. The absorbent layer 108 is arranged on the outlet head 107. The air flow source 112 is arranged to pass air flow through the outlet head 107, and the agitator 121 is arranged to actively agitate the outlet head 107.

[134] The device 101 has a circular upper section 105 located towards a first end of the device 101 and a handle 103 located towards a second end of the device 101. As illustrated, the second end of the device 101 is distal to the first end of the device 101.

[135] The upper section 105 includes the outlet head 107 through which air flow passes. The outlet head 107 is covered by the absorbent layer 108. In this example, the absorbent layer 108 is made from an absorbent material. Air flow 116 is generated by the air flow source 112 within the device 101 which is powered by a power cable 111. The handle 103 has a control interface 104 on one of its sides which can be used to control the device 101.

[136] In use, a user of the device 101 grips the handle 103 and positions the upper section 105 so that air flow from the outlet head 107 is directed onto a target area of the user's body for drying. This may allow the user to dry hard to reach parts of the body.

[137] The user can move the upper section 105, using the handle 103, so that the absorbent material 108 contacts with the target area of the user's body. The absorbent material 108 thus aids in the drying process.

[138] In use, air is blown through the outlet head 107 and through the layer of absorbent material 108. This helps to dry the target area more quickly. In addition, the air flow 116 through the absorbent material 108 helps to dry the absorbent material 108, in order to help to avoid the absorbent material 108 from becoming saturated with moisture. The layer of absorbent material 108 also includes an aperture 109 through which air flow 116 passes. The aperture 109 can be used to direct a more intense air flow over a localised area. The aperture 109 may also help to avoid excessive build up in pressure, should the absorbent material 108 become saturated with moisture. [139] The drying device 101 comprises an extendable section 110 between the handle 103 and the upper section 105. The extendable section 110 can be used to increase the distance between the handle 103, which the user holds, and the outlet head 107, through which air flow 116 passes. The extendable section 110 may also be retracted to decrease the distance between the handle 103 and the outlet head 107. Increasing or decreasing the distance between the handle 103 and the outlet head 107 may allow the user to access harder to reach areas of the body for drying.

[140] The drying device 101 also has a mounting 102 attached to the top of the upper section 105. The mounting 102 is arranged so that the device 101 can be attached to a wall bracket when storing the device 101.

[141] Referring to Figure 17, the air flow source 112 comprises a fan 113 which is powered by an electric motor 115. As is illustrated by the arrows in Figure 17, air enters the device 101 through an inlet 117, and the air flow 116 generated by the fan 113 passes through a channel 119 and exits the device 101 through the outlet head 107. In doing so, the air flow passes through the layer of absorbent material 108. There is a heating element 120 positioned within the channel 119 which can be activated to heat the air in order to assist in the drying process. It is to be appreciated that in some alternatives the heating elements may be positioned between the inlet 117 and the air flow source 112.

[142] In this embodiment, the agitator 121 is an electric motor 121 which is mechanically coupled to the outlet head 107 via a shaft 122. It would be possible to arrange the agitator 121 such that it is internal to the outlet head 107. The electric motor 121 causes the shaft 122 to rotate which in turn causes the outlet head 107 to rotate about a first rotational axis 133. The motor 121 may be arranged to rotate the outlet head 107 in complete rotations either in a clockwise or an anti-clockwise direction. The motor 121 may be arranged to rotate the outlet head 107 in a cycle, first though a partial rotation in the clockwise direction followed by a partial rotation in the anti-clockwise direction.

[143] In this example, the first rotational axis 133 is perpendicular to the main axis 131 of the device 101. This may allow the user to position the device 101 such that the layer of absorbent material 108 contacts the target area without the user having to bend the wrist. [144] As the outlet head 107 rotates, the layer of absorbent material 108 rotates also. This rotational motion helps to diffuse air flow through the absorbent material 108 and onto the target area. This may assist in drying the target area more effectively.

[145] The agitator 121 may comprise a vibration motor for vibrating the outlet head 107. The agitator 121 may comprise a linear motor for providing linear motion to the outlet head. A combination of agitation in the form of vibration, rotation and/or linear motion may be provided. Alternatively, agitation in the form of vibration, rotation and/or linear motion may be provided separately.

[146] Although, an electric motor and a vibration motor have been used as examples for the agitator 121, it would be possible for the agitator 121 to comprise any other means capable of providing active agitation. Active agitation by the agitator 121 of the outlet head 107 results in movement of the outlet head 107 without requiring direct physical forces external to the device. This may be contrast with, for example, an outlet head on a free swinging pivot, where movement of the outlet head is merely the result of a user moving the device and/or the effect of gravity.

[147] The control interface 104 on the handle 103 of the device 101 can be operated by a user in order to control the air flow source 112, the heating element 120 and the agitator 121. Using the control interface 104, the user is able to control the intensity of the air flow provided by the air flow source 112, the amount of heat provided by the heating element 120, and the speed of rotation and/or vibration provided by the agitator. The control interface 104 could be used to turn off/on the air flow source 112, the heating element 120 and/or the agitator 121. For example, the user may decide to activate the air flow source 112 and the agitator 121 without activating the heating element 120. In another example, the user may decide to activate the agitator 121 without activating the air flow source 112 or the heating element 120.

[148] The user may use the control interface 104 to control the heating element 120 in order to select an output temperature for the airflow. The output temperature may be anywhere between 20°C and 60°C. There may be a 'low' setting for the heating element 120 where the output temperature of the airflow is between 20°C and 30°C. There may be a 'medium' setting for the heating element 120 where the output temperature of the airflow is between 30°C and 40°C. There may be a 'high' setting for the heating element 120 where the output temperature of the airflow is between 40°C and 60°C. It is to be appreciated that other temperature settings and temperature ranges may be implemented.

[149] The user may use the control interface 104 to control the air flow source 112 in order to select the intensity of the air flow 116. There may be a 'low', 'medium' and 'high' setting for the air flow source 112.

[150] The user may use the control interface 104 to control the agitator 121 in order to select the intensity of agitation. There may be a 'low' setting for the agitator 121 where the speed of rotation of the outlet head 107 is between 10 rpm and 20 rpm. There may be a 'medium' setting for the agitator 121 where the speed of rotation of the outlet head 107 is between 20 rpm and 30 rpm. There may be a 'high' setting for the agitator 121 where the speed of rotation of the outlet head 107 is between 30 and 40 rpm. It is to be appreciated that other agitation settings and speeds may be implemented.

[151] The outlet head 107 comprises a plurality of support members 123. The support members 123 are arranged upstanding on the surface of the outlet head 107 providing a support surface for the layer of absorbent material 108. This support surface helps to prevent the absorbent material 108 from flexing inwards away from the target area. It also provides a massaging effect. In this example, the upper section 105 comprises a guard portion 124 surrounding the outlet 106. The guard portion 124 is used to protect the outlet head 107 and the layer of absorbent material 108.

[152] In this example, the handle 103 comprises a power unit 129 at the opposite end of the device 101 to the upper section 105. The power unit 129 comprises a battery which is used to power the device 101. The battery can be charged by a docking station 127 powered by a power cable 125. The device 101 can be docked into the docking station 127 for charging and removed from the docking station 127 for use. The handle 103 comprises a removable cover which provides access to the battery so that it can be replaced. The device 101 may be powered either by a battery or mains power or both. [153] Preferably, the device 101 is waterproof. The docking station 127 may charge the battery by inductive charging. The outlet head 107 may be removably attached to the device 101 by bayonet lugs, a threaded fit or an interference fit or any combination thereof.

[154] Referring to Figures 18A and 18B, the outlet head 107 comprises a support disc 135 with a top surface upon which the support members 123 are arranged. The layer of absorbent material 108 covers the support members 123 and is attached to the outer wall of the support disc 135. In this example, the aperture 109 is in the centre of the layer of absorbent material 108.

[155] Each support member 123 is a short prong made from a material such as rubber, silicone, or plastic. There are apertures 134 between the support members 123 through which air flow can pass. The support members 123 assist in maintaining the absorbent material 108 in contact with the target area whilst allowing air flow through the material 108.

[156] The layer of absorbent material 108 may comprise a textile or fibre material.

Materials such as lamb's wool, microfiber or terry-towelling may be appropriate.

[157] The support disc 135 comprises a groove 136 in its outer wall into which the edges of the layer of absorbent material 108 can be inserted and held in place. The edges of the layer of absorbent material 108 are adapted to lock into place in the groove 136. In one example, the absorbent material 108 may have an elasticised portion for engagement with the groove 136. The absorbent material 108 can be removed from the support disc 135 for cleaning and then reattached to the outlet head 107. Alternatively, the absorbent material 108 may be removed from the support disc 135, thrown away and replaced with a fresh layer.

[158] Once the outlet head 107 has been removed from the device 101 it is possible to connect a different outlet head onto the device 101 in its place. Figure 19 illustrates a perspective view of a washing head 137 which may be used instead of the original outlet head 107. The washing head 137 comprises a support disc 135 upon which a plurality of brushes 139 are arranged. Thus, the washing head 137 may be used instead of the layer of absorbent material 108 for cleaning rather than drying. When operating with the washing head 137, the agitator 121 may actively agitate the washing head 137. In some examples, the air flow source 112 may be deactivated when the washing head 137 is used. In other examples, the air flow source may be arranged to pass air flow through the washing head 137. In some examples the user may selectively, through the control interface 104, activate and deactivate the air flow source 112.

[159] Figure 20 illustrates a perspective view of an applicator head 141 which may be used instead of the original outlet head 107. The applicator head 141 comprises a support disc 135 upon which an applicator surface 143 is arranged. The applicator head 141 may be used for applying creams and the like rather than for drying or cleaning. In this example, the applicator surface 143 does not have an aperture as illustrated in Figure 18A. The applicator surface 143 may comprise a sponge, fine-sponge and/or soft moulded plastic material. When operating with the applicator head 1041, the agitator 121 may actively agitate the applicator head 141. In some examples, the air flow source 112 may be deactivated when the applicator head 141 is used. In other examples, the air flow source may be arranged to pass air flow through the applicator head 141.

[160] Figure 21 illustrates a cross-sectional view of an alternative handheld drying device 145. The components of the alternative device 145 are the same as those described above. However, in this example, the outlet head 107 is arranged to rotate about an axis that is parallel with the main axis 131 of the device 145. Thus, the user is able to point and press the end of the device 145 onto and target area for drying.

[161] The devices described above could be provided as a kit of parts for assembly into either a drying device, a washing device or an applicator device, depending on which removable head is attached to the device. Thus, the device(s) described above may be considered a grooming device with multiple functions. The multi -function handheld device may be used in modes for drying, washing and/or applying creams and/or ointments to the human body.

[162] It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the above-described embodiments, without departing from the broad general scope of the present disclosure. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
