Field of the invention

This invention relates to a washing apparatus for washing a vessel and/or a lid, and methods of washing the same.

Background to the invention

Washing apparatus, such as dishwashers and the like, can be used to wash a wide variety of items, such as vessels and lids. Known dishwashers often come with a number of wash cycles, which are typically run for tens of minutes, or hour(s). Known dishwashers typically use a detergent capsule to clean the dishes.

Rinsers, such as those used in hospitality sectors, can be used to quickly rinse a drinks vessel, such as a drinks glass. Known rinsers are often messy to use, with the rinsing fluid being prone to splashing the user or surrounding environment. Furthermore, at least some known rinsers do not wash or clean the vessel. They are simply used to rinse the vessel. For example, rinsing might be carried out after the vessel has been washed by hand or by another appliance.

Hand washing dishes in a sink is time consuming, laborious, and can be wasteful of materials, particularly if a small number of dishes is to be cleaned. Furthermore, hand washing dishes requires the use of detergent and/or hot fluid, such as water, particularly due to the typical environment used to carry this out (e.g. a domestic kitchen sink). There has been a drive towards sustainable use of materials. For example, re-usable vessels, as opposed to disposable vessels, are gaining traction, particularly for hot beverages such as coffee and tea, and for cool beverages, such as water, soft drinks and the like. There should be a corresponding drive to wash such vessels (and lids) in a more resourceful and quick manner.

It would be desirable to provide a washing apparatus that could be used to clean a vessel, or a lid for the vessel, or both, which is efficient to use for a small number of dishes, such as for a single vessel/lid. It would be desirable to provide an apparatus that can wash a vessel and/or lid quickly, to ensure that users are more likely to continue to use the apparatus (and not resort to wasteful, slow, known methods of washing dishes).

It would be desirable to provide a washing apparatus that can clean an item quickly and that is easy to operate.

The present inventors have appreciated the drawbacks with known washing apparatus and methods of washing items such as vessels/lids.

In the first, unloaded state 18d, the loading frame 18f is in a first position, and in the second, loaded state 18e, the loading frame 18f is in a second position. The washing module 18 is operable to move the loading frame 18f between the first position and the second position.

The first position of the loading frame 18f is located above the second position thereof in the direction of the longitudinal axis 1z of the washing apparatus 1 .

The chamber 20 of the washing module 18 is configured to receive at least a portion of the loading frame 18f therein.

In the first position, the loading frame 18f extends vertically beyond the chamber 20 of the washing module 18, and in the second position, the loading frame 18f is located within the chamber 20.

With reference to Figs. 4c and 4d, and 5e and 5f, each vessel fluid outlet 16a is arranged to be adjacent, in use, to the vessel engagement portion 6 and to the vessel 2, when the washing module 18 is in the second, loaded state 18e. The first vessel fluid outlet 16a’ is located at the floor portion 18a of the washing module 18 and the second vessel fluid outlet 16a” is located at a side portion 18b of the washing module 18.

The lid fluid outlet 16b is arranged to be adjacent, in use, to the lid engagement portion 8 and to the lid 4, when the washing module 18 is in the second, loaded state 18e.

The washing apparatus 1 comprises a loading mechanism configured to move the loading frame 18f between the first position and the second position. In this embodiment, the loading mechanism moves the loading frame 18f in a linear direction, vertically up and down, along the longitudinal axis 1z of the washing apparatus 1. The loading mechanism includes a linear actuator.

With reference to Fig. 1 d, the washing module 18 comprises a cover 34, configured, in use, to cover the vessel 2 and the lid 4 when the washing module 18 is in the loaded state 18e. The cover 34 encloses the washing module 18, and prevents or mitigates fluid escaping from the washing module 18. The cover 34 is located at the top portion 18c of the washing module 18.

The cover 34 is moveable between a first, open position (Fig. 1e) and a second, closed position (Fig. 1 d), and is connected to the washing module 18 by a hinge. The washing apparatus 1 includes an actuator for moving the cover 34.

The cover 34 includes a transparent window 34a for observing the inside of the washing module 18, and the chamber 20. The window 34a is optional, and some embodiments may do without a window 34a.

When the washing module 18 is in the second, loaded state 18e the cover 34 is moveable between the first, open position of the cover 34 and the second, closed position of the cover 34.

When the washing module 18 is in the first, unloaded state 18d, the cover 34 is in the first, open position of the cover 34 and cannot be moved to the closed position.

The loading frame 18f is movable from the second position to the first position when the cover 34 is in the first, open position. As shown in detail in Fig. 11 a and 11 b, the washing apparatus 1 comprises a drying module 44 for drying at least a portion of the vessel 2 and at least a portion of the lid 4. The drying module 44 has been omitted from the other figures for clarity. The drying module 44 is configured to provide pressurised air (an example of a drying fluid) to the vessel 2 and lid 4. The drying module comprises a blower for pressurising the air and providing it to the vessel 2 and lid 4. The drying module 44 could include any suitable components, and a compressor, or other component, could be used instead of a blower.

The drying module 44 comprises two elongate drying fluid outlets 46, one for the vessel 2 and one for the lid 4. The drying fluid outlets 46 are elongate slits in the drying module 44. The drying fluid outlets are configured to provide a curtain of air to the vessel and the lid, as is known in the field of drying modules. In this embodiment, the drying process avoids boiling the fluid, unlike conventional dishwashers and the like.

Figs. 12a and 12b illustrate another embodiment of the drying module 44, implemented in a cylindrical version with three drying fluid outlets 46 orientated towards the vessel 2, and two drying fluid outlets 46 orientated towards the lid 4. The drying fluid outlets 46 are also elongate slits in this version of the drying module 44.

The washing apparatus 1 comprises an electronic control module configured to control the washing of the vessel 2 and the lid 4.

The control module is configured to control the vessel actuator mechanism, the lid actuator mechanism, the intake of fluid from the source of fluid 14, the delivery of fluid from the fluid outlets 16, the operation of the heater, and the pressure of the pressurised fluid. The control module is configured to control which fluid is discharged from each fluid outlet 16. In this embodiment, the control module can switch between providing water and atomised water, and each fluid outlet 16 is independently controllable by the control module. Therefore, each of the three fluid outlets 16a’, 16a”, 16b, can output water or atomised water or have no output, independent of the status of each of the other fluid outlets. It will be understood that in other embodiments, each fluid outlet 16 may be configured to simply output the same fluid as each of the other fluid outlets.

The control module is configured to control the duration of fluid discharge from each fluid outlet 16.

As shown in Fig. 1e, the washing apparatus 1 comprises a user interface 36. The user interface 36 is configured to be a contactless interface. The user interface 36 is operable to receive one or more user input commands to control the operation of the washing apparatus 1 .

The user interface 36 comprises at least three manual, contactless user input elements 36a. Each contactless user input element 36a includes an infrared sensor for detecting a user input command, such as a hand being brought into close proximity thereto. The user input elements 36a are contactless buttons on a front region of the washing apparatus 1 . It will be understood that the buttons could be contacted by a user, but that the intended use is for contactless operation for improved hygiene.

In this embodiment, one user input element 36a controls the movement of the loading frame 18f between its first and second positions, and one user input element 36a initiates the washing of the vessel 2 and lid 4. Another user input element 36a controls the operation of a further fluid outlet 38, which will be described further below.

The washing apparatus 1 is configured to run a wash cycle to wash the vessel 2 and lid 4. The washing apparatus 1 is configured to proceed with the wash cycle in response to a single user input command to start the wash cycle.

The wash cycle includes a number of steps, which will be outlined below. In other embodiments, the steps, as outlined below, could be carried out in a different order unless the context provides otherwise. Furthermore, the present embodiment uses the order of steps provided below, but the apparatus 1 could be reconfigured to carry out the steps in a different order. Moreover, the fluids, durations of steps, etc can be reconfigured as desired.

The control module is configured to control the operation of the washing apparatus 1 and to run at least some of the steps of the wash cycle.

When the vessel 2 and lid 4 are located at the vessel engagement portion 4 and the lid engagement portion 8, with the washing module 18 in the first, unloaded state 18d, the wash cycle includes a step of configuring the washing module 18 from the first, unloaded state 18d, to the second, loaded state 18e. In this embodiment, this step moves the loading frame 18f down into the chamber 20. This step is carried out by the user interacting with one of the user input elements 36a, but in other embodiments, this step could be carried out automatically by the control module. Once the washing module 18 is in the second, loaded state 18e, the washing apparatus 1 can continue to run the wash cycle when the cover 34 is in the second, closed position. In this embodiment, the cover 34 is moved automatically by an actuator of the washing apparatus 1 , during the wash cycle but in other embodiments the cover 34 could be configured to be moved manually by the user.

The wash cycle includes a step of rotating the vessel engagement portion 6 about the axis of rotation 28, which rotates the vessel 2, for 15 seconds. At the same time as this step, the wash cycle includes a step of rotating the lid engagement portion 8 about the axes of rotation 30a, 30b, which rotates the lid 4, for 15 seconds. Thus, the wash cycle includes rotating both the vessel 2 and the lid 4 at the same time. This step is carried out when the washing module 18 is in the second, loaded state 18e.

The wash cycle includes two steps of washing the vessel 2 and the lid 4, which in this embodiment are carried out at the same time as the rotation of the vessel 2 and the lid 4. In this embodiment, the wash cycle is configured to provide heated atomised water to the vessel 2 for 5 seconds, and then heated water to the vessel 2 for 5 seconds. The wash cycle is also configured to provide the same two wash steps to the lid 4: heated atomised water for 5 seconds followed by heated water for 5 seconds. Washing of the vessel 2 and the lid 4 therefore take place substantially simultaneously. In this embodiment, the vessel 2 and lid 4 are rotated for 15 seconds, and during the first 10 seconds of that time, the two wash cycles are carried out. In this embodiment, each fluid outlet 16a’, 16a”, 16b, provides the same washing steps. In other embodiments, a single wash step for the vessel 2 and lid 4 of water may be sufficient, and as disclosed herein, other fluids and durations may be used. In this embodiment, the water and atomised water are heated to between 70 degrees Celsius and 90 degrees Celsius.

In the final 5 seconds of the vessel 2 and lid 4 being rotated, the wash cycle includes a drying step for drying the vessel 2 and lid 4. The drying step includes providing pressurised air to the vessel 2 and the lid 4 for 5 seconds. The drying step therefore takes place at the same time as rotation of the vessel 2 and the lid 4.

The wash cycle is configured to carry out the drying step after the steps of washing the vessel 2 and lid 4.

The wash cycle is configured to return the vessel engagement portion 6 to the same final position each time, and to return the lid engagement portion 8 to the same final position each time.

Next, the wash cycle will automatically lift the cover 34, to the open position subsequent to the wash step(s) and drying steps having been carried out, and when the rotation of the vessel engagement portion 6 and lid engagement portion 8 has ended.

Once the cover 34 is in the open position, the wash cycle is configured to end by configuring the washing module 18 from the second, loaded state 18e, to the first, unloaded state 18d. In this embodiment, this is done automatically by the washing apparatus 1 .

The wash cycle is configured to have a total duration of 20 seconds.

With reference to Fig. 1e, the washing apparatus 1 comprises a potable water source 37 (an example of a further fluid transfer device), comprising a water inlet connectable to a source of potable water, and a further fluid outlet 38 for dispensing potable water. The further fluid outlet 38 is spaced from the washing module 18.

In this embodiment, the further fluid outlet 38 is a potable water tap.

The potable water source 37 includes a drain 40 for collecting water from the further fluid outlet 38. The drain 40 is located adjacent to the washing module 18, and below the further fluid outlet 38.

The frame 42 is adapted to be locatable adjacent to a wall, or a planar wall. The frame 42 is adapted such that the side walls 42a are locatable adjacent to a support structure. The support structure could be a work top, a bench, a table, a kitchen-support structure, a desk, a shelf, or the like. The frame 42 is adapted such that the side walls 42a thereof are locatable adjacent to an end portion of the support structure. The frame 42 is adapted to fit within a frame accommodating portion of the support structure, such as a notch, or hole, or the like, in the support structure. For example, the support structure could be a work top, having a hole cut therein, and the frame 42 is adapted to fit within the hole. The washing apparatus has a height of between 1.1m and 1 5m, a depth of between 0.4m and 0.6m, and a width of between 0.5m and 0.65m.

Although not shown, the washing apparatus 1 could comprise a fluid circulation apparatus configured to recycle at least some of the fluid discharged from the one or more fluid outlets 16. The fluid circulation apparatus could be configured to collect the fluid used to wash the vessel 2 and/or lid 4. The fluid circulation apparatus could include one or more filters for filtering the collected fluid. The fluid transfer apparatus 10 could be configured to provide the collected fluid, either alone or in combination with fluid from the source of fluid 14, to the, or each fluid outlet 16.

Whilst in the embodiment illustrated and described herein the control module is an electronic control module, in other embodiments any suitable control module could be used, such as a computing device, or the like.
