Description

A DISHWASHER

The present invention relates to a dishwasher comprising a drawer in which items to be washed are placed.

It is rather difficult to wash items of small sizes which have many indentations. Therefore, cutlery baskets are provided on the washing cabinet in which small-sized items such as forks and spoons are placed for being well-washed and not being dashed around during the washing process. This enables the washed items to be even cleaner, and prevents deformations on the items and on the machine likely to occur due to items dashing around. As well as being positioned at a region on the lower basket, lately these cutlery baskets are preferred to be located in regions close to the ceiling of the washing cabinet. This enables enlarging the washing capacity of the lower basket and thereby being able to wash items occupying larger spaces or a higher number of dishes. Water directly reaches on the basket disposed at the ceiling area. In addition, items are enabled to be arranged more orderly. Smaller sized items are thus enabled to be washed more effectively. However, the baskets placed between the ceiling and the upper basket, delimit the space for placing the items on the upper basket. Taller items such as wine glasses placed on the upper basket snag on the cutlery basket disposed above the upper basket. This may lead to not being able to place taller items on the upper basket, or deformation of the items or of the cutlery basket.

State of the art international patent application document no. WO2014102737 discloses a dishwasher comprising a basket which can be utilized in varying sizes.

The aim of the present invention is to realize a dishwasher whose washing cabinet volume can be used efficiently.

The dishwasher realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims comprises a body, and a washing cabinet provided on the body. A drawer is provided in the washing cabinet proximate to the ceiling of the washing cabinet, on which small-sized items are placed to be washed. The drawer comprises a frame forming its edges, at least one side surface slidingly displaceable on the frame, and an intermediate surface disposed between the side surfaces. The intermediate surface has an upper position in which it rests side-by-side with the side surfaces, enabling placing items on almost all of the area within the frame, and a lower position in which it moves downwards, enabling the side surfaces to join.

The dishwasher of the invention comprises a control member controlling displacement of the intermediate surface between the lower position and upper position, and the sliding motion of the side surfaces on the frame. The intermediate surface displaces between the lower position and the upper position by means of the control member. The washing cabinet volume is thus used more efficiently.

In an embodiment of the invention, the dishwasher comprises a movement mechanism enabling the intermediate surface to displace between the upper position and the lower position. The movement mechanism comprises a bearer frame on which the intermediate surface is placed, at least one carrier member enabling the bearer frame to be moved in vertical direction, at least one guide member on which the carrier member slidingly moves, and an actuator. An end of the actuator is disposed on the carrier member. A worm gear is provided at the other end of the actuator. The carrier member slidingly moves on the guide member. This enables the intermediate surface to move in vertical direction.

In an embodiment of the invention, the dishwasher comprises a control member detachably attached at the end with the worm gear of the actuator.

In an embodiment of the invention, the dishwasher comprises a movement mechanism having a first gear track, a middle gear and a main gear. The first gear track extends in vertical direction so as to be parallel to the guide member. The control member enables the worm gear to move by being triggered by the user. The rotating worm gear transmits this motion to the middle gear. The middle gear transmits its motion to the main gear, thereby enabling the intermediate surface to displace between the lower position and the upper position.

In an embodiment of the invention, the dishwasher comprises a movement mechanism having a second gear track and a back gear. The second gear track is disposed vertically on the rear edge of the bearer frame. The back gear advances on the second gear track. This enables the bearer frame to move in vertical direction.

In an embodiment of the invention, the dishwasher comprises a movement string whose one end is disposed on the control member and whose other end is connected to the side surface.

In an embodiment of the invention, the dishwasher comprises a control member detaching from the actuator by being pulled in opposite direction of the actuator. The control member is movable in horizontal direction when detached from the actuator.

In an embodiment of the invention, the dishwasher comprises a protective cover having a slot on which the control member moves in horizontal direction.

In an embodiment of the invention, the dishwasher comprises side surfaces slidingly moving on the frame upon moving of the control member in horizontal direction. The side surfaces can be used in various positions by sliding on the frame.

In an embodiment of the invention, the dishwasher comprises a rotatable member provided on the side surface, enabling the side surface to slidingly move.

In an embodiment of the invention, the dishwasher comprises a frame on which the side surfaces are joined when the intermediate surface is in lower position. The sides of the frame remain hollow thanks to the side surfaces sliding and joining on the frame. This enables placing larger items on the basket disposed below the drawer.

The dishwasher realized to achieve the aims of the invention is illustrated in the accompanying drawings, wherein:
