Definitions
- the present disclosure relates to a dishwasher. More particularly, the disclosure relates to the design of the bottom of a tub of a dishwasher.
- a dishwasher cabinet may need to fit within a space that is 817.5-877.5 mm high, 595 mm wide and 570 mm deep.
- a dishwasher has a tub, in which items to be washed can be placed.
- a dish rack is situated, in which the items to be washed are placed.
- Drawer dishwashers are known from e.g. US 6, 460, 555Bl and US 6,447,081Bl.
- a drawer dishwasher has at least one drawer, each drawer comprising a tub.
- US 6,447,081 Bl a drawer dishwasher having two drawers arranged on top of each other in a cabinet is described.
- an object of the invention is to maximize usage of the space within the dishwasher, to be able to receive large items in a tub of the dishwasher.
- the object of the invention is solved by the characterizing part of claim 1 in which a dishwasher is arranged such that a tub bottom is downwardly inclined from a first portion of the tub close to a first side of the tub towards a second portion of the tub close to a second side of the tub, which second side is situated opposite to the first side of the tub, such that a distance between the tub bottom and a plane comprising an upper edge of the tub increases towards the second portion of the tub.
- the dishwasher allows for receiving large objects to be washed, such as plates with a large diameter, in the second part of the tub, while providing a space for functional components of the dishwasher below the tub and still being able to keep the total height of the dishwasher at a limited height.
- the tub bottom is downwardly inclined from a front part of the tub towards a rear part of the tub. Due to this inclination of the bottom of the tub, a rather large plinth area can be provided below the bottom of the front side of the dishwasher.
- a kitchen can be equipped with uniform plinths for all appliances of a kitchen, including the dishwasher, which is a demand from some kitchen manufacturers.
- the plinth area provided by the invention would allow the user to stand close to the kitchen counter without his or her feet striking against the dishwasher.
- a filter receptacle is placed at the lowermost position of the tub bottom.
- the inclination would, at operation of the dishwasher, direct water in the tub to the filter receptacle. Thereby, water will circulate quicker through a pump circulation system of the dishwasher, which would result in low water consumption.
- the filter receptacle is placed in a back corner of the tub.
- the invention is especially advantageous in a drawer dishwasher wherein the space constraints are normally stricter than for conventional dishwashers.
- Fig. 1 schematically illustrates, in cross section, a side view of a drawer dishwasher including two drawers.
- Fig. 2 schematically illustrates, in cross section, a side view of a dishwasher drawer according to an embodiment of the invention.
- Fig. 3 schematically illustrates a cross section, in section I-I in figure 2, of the dishwasher drawer according to an embodiment of the invention.
- Fig. 1 illustrates a drawer dishwasher 20, according to an embodiment of the invention.
- the dishwasher 20 has a front portion 23, which in a normal installation would be visible to the user, and a rear portion 24, which in the normal installation would be non-visible to the user, e.g. since it faces a wall.
- the dishwasher 20 also has an upper portion 26, which normally faces the underside of a counter, under which the dishwasher is arranged.
- the dishwasher is typically positioned on a horizontal surface 25, such as a floor or a shelf.
- This dishwasher 20 has a first drawer 21 and a second drawer 22 arranged on top of each other.
- the invention may be used for other configurations of dishwashers, such as conventional dishwashers or drawer dishwashers comprising only one drawer, or comprising more than two drawers .
- Fig. 2 schematically illustrates a dishwasher drawer 1 according to an embodiment of the invention, which may be arranged in a drawer dishwasher 20.
- the drawer 1 has a washing tub 2 for receiving plates, cutlery, glasses, bowls, etc. that are to be washed.
- the inner volume of the tub 2 is limited by a tub bottom 7, substantially vertical inner sides 5, 6 of the tub and a substantially horizontal plane 11 comprising an upper edge of the tub.
- the horizontal plane 11 comprising the upper edge of the tub 2 is normally closed by a lid, which can be opened to allow for access to the tub from above.
- the tub bottom 7 is downwardly inclined from a front portion of the tub towards a rear portion of the tub.
- the front portion of the tub is adjacent to a vertical front side 6 of the tub facing a front side of the dishwasher drawer 1, and the rear portion of the tub is adjacent to a vertical rear side 5 of the tub facing a rear side of the dishwasher drawer. Thanks to the inclined tub bottom 7, the height of the tub increases in a direction from the front portion of the tub towards the rear portion of the tub. Due to this measure, large objects can be placed in the rear portion of the tub 2, without having to increase the total height of the tub.
- the tub also has a filter receptacle 10 arranged in the bottom 7 of the tub.
- the filter receptacle 10 is further connected to a washing pump (not shown) via a pump inlet (not shown) .
- the filter receptacle 10 is preferably arranged in the lowest part of the tub bottom 7, preferably close to the rear side 5 of the tub 2. Thereby, the inclination of the tub bottom 7 would, at operation of the dishwasher, direct water in the tub to the filter receptacle 10. The result would be a quick circulation of water through the pump circulation system of the dishwasher, and low water consumption.
- the functional components 4 are arranged to allow for a low total height of the drawer. For this reason, the functional components placed in the enclosure 3 below the tub are essentially placed outside the lowest portion of the tub. Thereby, the height of the enclosure 3 below the lowest portion of the tub can be very low.
- the tub bottom 7 has an inclination of about 3.5° to 10° relative to a horizontal plane, preferably about 4° to 7° relative to the horizontal plane, and most preferably about 5° relative to the horizontal plane. 5° has been found to be an optimal value for the inclination. If the inclination is lower than 5°, some drops of water may remain on the tub bottom. Then a number of drops of water have to accumulate before the water drops will flow into the filter receptacle. Also, if the inclination is higher than 5°, there will be too less space in the tub where the tub bottom has its highest altitude.
- the dishwasher drawer 1 preferably has a rotatable sprinkler arm 13 for spraying water into the tub; water which is circulated by a washing pump through a water circulation system from the tub via the filter receptacle 10 and the pump back to the tub.
- the sprinkler arm 13 may be arranged to rotate in a plane that is substantially parallel to the tub bottom 7. According to one embodiment, the sprinkler arm 13 is rotatably connected to the tub bottom 7.
- a dish rack for receiving the items to be washed.
- the dish rack is preferably situated close to the bottom of the tub and inclined with an inclination similar to the inclination of the tub bottom.
- the tub 2 extends further outwards from a rear portion of the drawer 1 than the enclosure 3, such that a plinth area 12 is created at the bottom of the front of the dishwasher drawer, outside the drawer.
- the user of the dishwasher may place his or her feet in the plinth area 12, such that he or she can take an ergonomically advantageous position when e.g. placing dish in the dishwasher.
- the tub bottom 7 When the tub bottom 7 is downwardly inclined from a front portion to a rear portion it will be possible to have a high relationship between the highest tub height D and the total height of the drawer, and anyhow be able to design the plinth area 12 in an ergonomically advantageous way. This is achieved by inclining the tub bottom from a front portion of the tub and downwards towards a rear portion of the tub . Then it is possible to make the distance between the tub bottom at the front portion of the tub and the floor, when the drawer 1 stands on a floor, high enough for a pair of feet to conveniently fit under the front part of the dishwasher.
- a front portion of the tub bottom 7 and a front portion of the drawer bottom 8 are connected by a downwardly inclined portion 9 limiting the plinth area 12.
- the downwardly inclined portion may be curved for achieving a more ergonomically advantageous embodiment.
- the plinth area 12 typically has the following measures:
- the drawer bottom 8 is typically retracted from a cabinet front of the drawer dishwasher by about 140 mm; the height from the floor to the bottom of the dishwasher, at the front portion of the drawer, is typically about 100 mm, including the distance from the drawer bottom 8 to the tub bottom 7 at the front of the tub.
- the drawer can be equipped with a uniform plinth, which is a demand from kitchen manufacturers for achieving a uniform shape for all appliances at a kitchen worktop.
- Figure 3 schematically illustrates a cross section in section I-I of a rear section of the dishwasher drawer in figure 2, according to an embodiment of the invention.
- Figure 3 shows side portions 14, 15 of the tub, the tub top plane 11, the tub bottom 7 and the bottom 8 of the drawer.
- the filter receptacle 10 is arranged in a lowermost portion of the tub bottom 7 in the rear portion of the tub, and the surrounding tub bottom will be on a higher level than the portion in which the filter receptacle is arranged.
- the filter receptacle 10 and the lowermost portion are placed in a back corner of the tub bottom 7. Thereby, there will be more space for the functional components 4 compared to if the filter receptacle 10 is placed in the middle of the tub 2, or in the middle of the rear portion of the tub.
- all components provided in the enclosure 3 may be mounted in an underside of the tub bottom 7. Hence, there need not be any drawer bottom 8, or actually, the drawer bottom would then be the tub bottom 7.
