Description

TECHNICAL FIELD

The present disclosure relates to a dishwasher comprising a rack with changeable width.

BACKGROUND

A dishwasher is an apparatus for washing items using a force of washing liquid sprayed onto the items. A dishwasher comprises a washing chamber in which items to be washed are positioned, usually in racks. Typically, dishwashers comprise one or more spray arms spraying washing liquid, e.g. a mixture of water and detergent, onto the items to clean them. The washing liquid is collected in a sump at a bottom of the washing chamber. A circulation pump of the dishwasher is fluidly connected to the sump and pumps washing liquid from the sump to the spray arms during a wash cycle.

A dishwasher typically comprises two or more racks in which the items to be cleaned can be positioned. The racks are usually displaceably into and out of the washing chamber via guide rails so as to facilitate loading and unloading of items into and out of the racks. There are many requirements on today's dishwashers, and they are expected to manage simultaneous washing of various types of items having different sizes, such as dishware and cutlery including plates, bowls, glasses, wine glasses, champagne glasses, mugs, pots, pans, and the like. Due to the limited space of a washing chamber, this poses some problems. Moreover, some items must be positioned and oriented in a certain position and orientation relative the washing chamber so as to be cleaned properly. As an example, wine glasses, champagne flutes, and the like, must be positioned in the washing chamber such that washing liquid can reach the liquid accommodating portion of the glass and such that the washing liquid can flow out of the liquid accommodating portion of the glass. In addition, items must be positioned in the washing chamber such that items do not hinder movement of one or more spray arms of the dishwasher.

Attempts have been made to provide a more flexible interior of a washing chamber, such as providing removable sections of the interior, providing sections of the interior having changeable sizes, and the like. However, problems still exist when it comes to provide a flexible interior of a dishwasher. Moreover, many of the existing solutions are cumbersome and non-intuitive to use. As an example, in solutions requiring a user to remove a section of a rack when the user wants to load a large item into the washing chamber, the user has to store the removed section at another location during the wash session.

Furthermore, some of the existing solutions for providing a more flexible interior comprise a rack with changeable size wherein a frame connects the rack and a guide rail mounted to a side wall of the washing chamber. In such a solution, the frame limits the obtainable clearance space. Moreover, in such a solution, the frame may strike into items extending into the clearance space upon displacement of the rack into and/or out of the washing chamber, as well as upon displacement of a second rack into which the items are positioned.

Furthermore, generally, on today's consumer market, it is an advantage if products, such as dishwasher and their associated components, have conditions and/or characteristics suitable for being manufactured and assembled in a cost-efficient manner.

SUMMARY

It is an object of the present invention to overcome, or at least alleviate, at least some of the above-mentioned problems and drawbacks.

According to an aspect of the invention, the object is achieved by a dishwasher comprising a number of walls forming a washing chamber, wherein the number of walls includes a top wall and a first and a second side wall. The dishwasher further comprises a first rack and a first and a second guide rail. The first rack is supported in the washing chamber via the first and second guide rails. The first rack comprises a first rack section and a second rack section, the first rack section being movably arranged relative the second rack section to enable change in horizontal width of the first rack. The first guide rail is movably arranged relative the washing chamber in directions towards and away from the first side wall.

As a result, a dishwasher is provided in which the first guide rail will move towards and away from the first side wall upon movement of the first rack section relative the second rack section, i.e. upon change in horizontal width of the first rack. This because the first rack is supported in the washing chamber via the first and second guide rails and the first guide rail is movably arranged relative the washing chamber in directions towards and away from the first side wall.

Accordingly, due to these features, a clearance space is provided between the first side wall and the first guide rail for larger items to extend into when the first rack section is moved towards the second rack section to a retracted position. Accordingly, when the first rack section is moved to the retracted position, the first guide rail is moved to a position where it is less likely to hinder loading of objects into the washing chamber. In this manner, a more flexible interior of the dishwasher is provided.

Furthermore, a dishwasher is provided in which portions of the interior is less likely to strike into items extending into the clearance space upon displacement of the first rack into and/or out of the washing chamber, as well as upon displacement of a second rack into which the items are positioned. This because the first guide rail is arranged to follow the movement of the first rack section upon change in horizontal width of the first rack, thereby circumventing the need for a frame connecting the first guide rail and the first rack. Such a frame would limit the clearance space obtained when the first rack section is in the retracted position and could strike into items extending into the clearance space for example upon displacement of a rack into which such objects are positioned.

In addition, a dishwasher is provided in which a user can in a simple and intuitive manner obtain the clearance space simply by moving the first rack section towards the second rack section. Furthermore, if the clearance space is not needed and the user wants to obtain more space in the first rack, the user can in a simple and intuitive manner obtain more space in the first rack simply by moving the first rack section in a direction towards the first side wall. Moreover, a dishwasher is provided circumventing the need for removing one or more sections of the interior for providing a clearance space for larger objects. Thus, as a further result of these features, a user-friendly dishwasher is provided which can be used in a simple and intuitive manner.
