Description:
DOMESTIC ELECTRICAL APPLIANCES

This invention relates to domestic electrical appliances. The term domestic electrical appliances includes such items as fridges, washing machines, tumble dryers, dishwashers, spin dryers and the like.

Most kitchens are equipped with several different domestic electrical appliances. Many modern kitchens are "fitted", that is to say they include a number of fitted cupboards, units, worktops and the like which are decorated or co-ordinated to provide a uniform decorative theme/colour scheme. Wood panelling is one typical popular decorative theme. The matching of domestic appliances to fitted kitchens often causes problems because most existing domestic electrical appliances are finished in white painted or plastic coated steel. Unless the fitted kitchen itself is to be white the existing appliances will not match the kitchen's decorative theme (and if the decorative theme was white painted wood panelling the appliance would not properly match the decoration even then) .

When f tting a new kitchen two options are available to obtain a uniform decorative theme which the kitchen's domestic appliances match. The kitchen's existing appliances can be built into units in the fitted kitchen: alternatively the existing appliances can be replaced with new "integrated" appliances, an "integrated" appliance being one which matches the kitchen's decorative theme.

The first option, viz building existing appliances into units, usually involves building a cupboard under a worktop into which the appliance is inserted. This is expensive and time consuming at the fitting stage. First, an extra cupboard is needed which adds to the expense of the fitted kitchen. Also, to enable the appliance to fit fully in the cupboard under the worktop a much wider worktop (usually 700mm or more) is needed,, than would normally be required with an integrated appliance. Further, the cupboard has to be sufficiently large to provide space on either side of the appliance. Also access to the appliance is awkward.

The second option, replacing the existing appliances with new integrated appliances which match the decoration of the kitchen is also expensive because it involves buying new appliances and discarding the existing appliances even though they may be perfectly servicable.

Various types of matched appliance exist. Some are painted in colours other than white: the majority include a panel, which is often made of wood, fitted to the door of the machine. A dishwashing machine having such a wood panelled door is disclosed in GB-A-2079589. EP-A-0080770 discloses a washing machine which has a fitted plastic door panels to which an (interchangeable) decorative panel is screwed.

However, whichever of the two options is chosen, buying integrated appliances, or building in the existing appliances, considerable expense is involved.

It is an object of the present invention to alleviate some or all of the above-mentioned problems.

Thus, according to a first aspect of the present invention, there is provided an assembly for attachment to a domestic appliance comprising:-

a plate, which is provided with magnetic means for releasably securing the plate to the appliance; and

hinge means mounted on the plate, said hinge means being adapted to receive a door or the like, the arrangement being such that the plate may be attached to a ferromagnetic domestic appliance and a door or the like may be secured to the hinge means to cover the front of the appliance.

Using the present invention a door (which matches a kitchen's decorative scheme), may be fitted to an existing domestic electrical appliance to enable the appliance to be matched to its surroundings. There is thus no requirement to either replace existing appliances.

The use of magnetic means enables the assembly to be easily fitted to a casing of domestic appliance without the need for tools and without drilling into

or otherwise affecting the existing appliance and thus can avoid impinging on any manufacturer's warranties on that appliance. The door and assembly may be easily removed from the appliance for servicing and in the event that the appliance breaks down and needs replacing it is a simple matter to remove the assembly from the broken appliance and attach it to a replacement domestic appliance.

In a preferred embodiment, the plate is securable to the appliance by means of rubber faced magnets.

In one embodiment the plate is generally planar this type is suitable for fitting to a side of the casing of domestic appliances such as fridges and dishwashers which have doors forming their front faces to enable the weight of any decorative panel to be supported by the casing via the hinges and not by the appliance's door.

Alternatively it may be an "L" shaped cross section defining two perpendicular surfaces one of which is securable to a front face of an appliance the other of which fits to a side of the appliance.

The plate may be made of extruded aluminium.

The plate may have a white coated inish to match a white appliance.

The assembly may include a door ready mounted to the hinge means.

The door may include a decorative panel releasably secured to the door, the panel being removable for replacement by a different panel having a different decorative design.

Preferably the door includes a frame or trim which extends around the perimeter of the door and in which the decorative panel may be mounted by sliding to avoid the use of screws or tools.

The trim or frame may include a handle which is removable and interchangeable with the trim for the lowermost part of the door to enable the door to be reversable in orientation so it can be adjusted to fit a domestic appliance and open in either a left handed or a right handed manner.

The trim and panel may be supplied in a variety of colours to blend with the existing cosmetic colours of the appliance and kitchen units and fittings.

Specific embodiments of the invention will now be described, by way of example only, and with reference to the accompanying drawings in which:-

Figure 1 is a perspective view of an assembly embodying the present invention;

Figure 2 is a further perspective view of the assembly of figure 1;

Figure 3 is a plan view illustrating the use of a safety strap when the assembly of figure 1 is secured to a washing machine; and

Figure 4 shows a plate for attachment to dishwashers.

Figure 5A is a plan view of a plate for attachment to fridges;

Figure 5B is a side view of the plate of figure 5A;

Figure 5C is a front view of the plate of figure 5A;

Figure 6 is a perspective view of a washing machine to which a door assembly embodying the present invention has been attached;

Figure 7 is a view of the machine and door assembly shown in Figure 1 with the door closed;

Figure 8 shows details of the handle on top of the frame;

Figure 9 show details of one corner of the frame of the door; and

Figure 10 is a view of the washing machine and door assembly shown in Figure 1, partly disassembled.

Referring to the drawings, Figure 1 shows a right angled plate 100 having an "L" shaped cross section defining two perpendicular plates 102 and 104. The length of plate 100 is 450mm. Plate 102 has a width of 100mm: plate 104 has a width of 115mm.

As seen in figure 2, the plates 102, 104, each carry two large rubber faced magnets 106. The magnets 106 are located on "facing" surfaces 102A and 104A of the plate 100 so that they can be used to secure the plate 100 to a right angled corner of a ferromagnetic object, viz a washing machine shown in figure 3.

As is best seen in figure 1, on the opposite face 102B of side 102 are upper and lower hinges 108A, 108B spaced 350mm apart. The hinges are located approximately 50mm from the top and bottom of the plate 102 respectively: they are standard face to face kitchen hinges.

Figure 3 shows the plate assembly 100 in use attached to a corner of a washing machine 110: the washing machine has a steel casing/cabinet and because steel is ferromagnetic, the magnets will hold the plate to the washing machine. A door (not shown) can then be placed over the washing machine and fitted to the hinges in the appropriate place, either, in situ, or after removing the magnetic plate from the washing machine. Since the plate assembly is held to the washing machine by means of magnet it is easy to adjust the position of the door by adjusting the location of the plate assembly. The weight of the door is supported by the casing/cabinet of the washing machine.

Figure 3 also shows an optional safety assembly which helps prevent the plate becoming accidentally dislodged from the washing machine 110. The assembly comprises a torsion strap 112, one end 114 of which is attached to the plate 104 by means of a counter sunk screw or tape (not shown), the other end of the strap being attached by means of one 116B of a series 116A, B, C, D, of holes in the strap to a pin on a tensioning screw holder 120. The tensioning screw

holder 120 fits on a rear corner of the washing machine cabinet and adjusting the tensioning screw 124 tensions the strap 122 to hold the plate 100 securely on the washer.

The right angled plate 100 is formed of aluminium which is extruded in the desired "L" shape. To receive the hinges, a hole is drilled in the aluminium plate and then the stainless steel bush is pressed into the aluminium, the bush being threaded so that the hinges 108A, 108B can be screwed against the plate.

The magnets 106 are permanent ferromagnets (to avoid deterioration with age or vibration), are mounted on 0.5mm sheet steel to improve the magnetic strength and have a 2mm rubber backing to prevent damage to the washing machine or the like which will also absorb some vibrations.

Figure 4, shows a plate 150 for attaching a door (not shown) to the front of a dishwasher, (not shown) . The plate is a right angled trapezium in shape. The base of the plate is 450mm long, one 153 of the parallel

sides of the trapezium is 300mm long, the other 154 is 120mm long. Three rubber faced magnets 156, are secured to the plate.

At the shorter side 154 of the plate, the plate is much thicker being sufficiently thick to define a face 157 which is perpendicular to the general surface of the plate and to allow a hinge to be mounted to it on which a door can be mounted.

In use, the plate 150 is attached to one side of a front loading dishwasher, and a similar plate (not shown), being a mirror image of plate 150, is attached to the opposite side of the dishwasher by means of magnets 156. The longer sides 153 are located at the rear of the dishwasher. A wooden door (not shown) or the like is attached to the plates by means of the hinges on the faces 157. The wooden door is attached to the door of the dishwasher in such a manner as to allow relative movement between the two but with the weight of the wooden door supported by the plate and dishwasher casing to avoid strain being put on the dishwasher's door/door mounting.

Referring to figures 5A, B and C, a rectangular plate 170, of sides 800mm by 300mm is shown. As is best seen in figure 5C, the plate comprises a thin generally planar portion 170A and a built-up portion 170B which is generally trapezoidal in cross section and which at its widest at one end is 20mm thick and defines a face 173 which is perpendicular to the planar portion 170A, compared to the rest 170A of the plate which is between 2 and 3mm thick. On one side of the planar portion 170A of the plate, there are three large magnetic pads, 172.

As is best seen in figure 5B, the plate has four holes drilled in the face 173 into which stainless steel threaded inserts are fitted to enable hinges, (not shown) to be fixed to the plate 170.

In use, the plate is mounted to the side of the casing of a fridge to which the fridge door is hinged and a decorative door or wood panel or door is attached to the plate via the hinges.

In order to enable the decorative door to open the fridge door when the same is opened, the fridge door handle is removed and a handle slider is mounted to the door in place of the handle, the handle slider comprising a protruding plate which fits, is held, and slides in a channel mounted on the back of the door panel, in a manner which is known in connection with integrated appliances.

Importantly, all the weight of the decorative door or wood panel, is carried by the plate and not by the fridge door.

Figure 6 shows a door assembly, generally indicated at 1, attached to the front 2A of a front loading washing machine 2. The washing machine has a round glass door 3 which projects from the front 2A of the machine. The door assembly comprises a bent plate 4 on which a door 6 is mounted by means of two hinges, an upper hinge 8A and a lower hinge 8B, located adjacent the corner 4A of the plate.

The plate 4 is "L" shaped in cross section. It comprises a generally rectangular piece of material formed into two substantially perpendicular surfaces 10A, 10B joined at the corner 4A. Surface 10A is rectangular and fits along the side of the washing machine: surface 10B is generally rectangular but includes a generally semi-oval shaped cut out portion 12. As can be seen from Figure 6 the semi-oval shaped cut out portion 12 prevents the plate impinging on the projecting glass door 3 when the plate 4 is fitted to the front of a front loading washing machine.

The plate 4 is made from a sheet of magnetic material covered with coloured plastic to match surfaces 10A and 10B to the colour of the appliance. This magnetic attraction between the plate and the metal front and one side of the washing machine secures the plate in place against the washing machine. An additional strong conventional magnet, not shown, may be added to the plate to increase the forces holding the plate to the machine, for safety reasons.

The door comprises two plastic panels, an inner skin or panel 14 and an outer skin or panel 16. A recess 18 which is adapted to receive the projecting door 3 of the washing machine when the door 6 is closed, is formed in the inner panel 14. The outer panel is flat. The outer panel 16 is glued to the base of the recess 18 of the inner panel 14. Apart from where the recess is glued to the outer panel, there is a space between the panels. This may be filled with a suitable material such as foam 18.

A trim, or frame, comprising a handle 20, side trims 22, 24 and base trim 26 are fitted around the perimeter of the door panels. The base of the handle base trim may be formed with a "T" shaped projection for sliding insertion into a corresponding shaped recess 30 in the door. A similar arrangement may be used for the side trims.

The base trim and handle are interchangeable to enable the door assembly to be fitted to an appliance in either a left handed or right handed manner by rotating the assembly through 180° and placing the plate on the other side of the washing machine.

The side trims and base trims defines walls 32 behind which the perimeter area of a decorative panel may be inserted so that it is held between the walls and the outer panel 16.

Two magnets 34 are provided on the door to form a catch when the door is shut.

The handle and trim are made of a plastics material.

The recess and cut out portion may be made sufficiently large to accomodate most makes of washing machine.

Although the description relates to a washing machine, the assembly may be used on any suitable domestic appliance.

The door assembly will fit straight onto a domestic appliance without the need to drill holes in, or provide fixing means on, or alter the appliance itself.
