Definitions

• the invention relates to a dishwasher with a substantially cuboid or parallelepipedic, open to the front housing and with an open-top washing container whose side walls have upper edges which extend parallel to the housing cover, the washing container for loading and unloading drawer-like out of the housing can be pulled out and completely inserted into the housing during the flushing operation, and wherein during the flushing operation at least a portion of the washing container rests against a portion of the housing under any intermediate layer of a seal.
• the invention particularly relates to a rinsing container in which the side walls have upper edges provided with seals, or a rinsing container against which lateral seals arranged on the housing during the rinsing operation.
• Such a dishwasher is known for example from WO 98/33426 A1.
• the advantages of such a drawer dishwasher are described in detail in this document.
• a problem with drawer dishwashers arises from the need to seal the open-topped rinse tank to prevent leakage of rinse liquid.
• a liquid-tight contact must be made between the cover of the housing - or parallel sealing strips on the housing side walls - and the edges that define the Spülakutician.
• flexible seals are used at the edges and / or on the housing.
• one of the sealing partners must exert one force on the other. In the front and rear of this force is achieved by the insertion movement, which is perpendicular to the sealing surface. At the lateral edges, however, the insertion movement is parallel to the two sealing surfaces. Provision must therefore be made to produce a force having a vertical component to the lateral sealing surfaces.
• WO 98/33426 A1 uses a washing container which is higher in the front than behind, so that the edges of the side walls are inclined backwards. With a correspondingly inclined cover or a corresponding sealing bar is then reached that the insertion movement is no longer parallel to the sealing edge and thus generates a force on the seal partners. From the oblique course of the edges, there are several disadvantages. On the one hand, the height of the washing container decreases, which reduces its capacity. On the other hand, any residual water left on the sloping edges runs backwards into the housing.
• WO 98/33426 A1 discloses variants with folding lids or "endless lids" mounted on rollers, which, however, have disadvantages in terms of their tightness.
• the lowering of seals by inflating the seal itself or an associated activating device is described in WO 98/33426 A1.
• the invention poses the problem of creating a structurally simple, yet functionally reliable way of sealing the rinsing container within the housing.
• the advantage achievable with the invention consists in the simple construction of housing and washing container, wherein in particular the cuboid shape or, where appropriate, the parallelepiped shape of the washing container can be maintained.
• this advantage is achieved in that the washing container decreases at least in the region of the upper edges over approximately the entire length either in terms of its outer dimensions in width from front to back or increases in terms of its internal dimensions in width from front to back, and that either the housing or a seal arranged on the housing has at least one contact surface adapted to the course of the rinsing container contour.
• seals are arranged at the upper edges of the rinsing, which also during the rinsing operation at a width from the front to the rear reduced area of the housing.
• seals are arranged in the inner edges formed by the housing side walls and the housing cover, and the width of the Area between the contact surfaces the seals also decreases from front to back. The arrangement of the seals in the housing remain protected and a risk of damage by the user of the dishwasher is low.
• the width-decreasing area is inclined inwards relative to the rest of the side walls.
• this area can be formed in a simple manner as a chamfer arranged at the outside of the side wall edges with a constant angle, but with increasing depth from the front to the rear.
• seals are arranged on the housing lid, which protrude into the rinsing container interior, and which are adapted to the contours of the washing with respect to their sealing effective contact surfaces.
• the arrangement of the sealing surfaces on the inside of the washing container prevents liquid that passes between the seal and sealing surface, runs out of the washing and thus enters the housing.
• the width-increasing region is inclined outwards relative to the rest of the side walls, because it then increases as a bevel arranged at the inside of the side wall edges with a constant angle, but with an increase from front to back Depth can be formed.
• the means may be formed as arranged on the housing side walls guide rails, which extend from the housing rear wall to the housing opening downwardly inclined.
• the means may be formed as rollers disposed one behind the other on the housing sidewalls, the axes of which lie on lines inclined downwardly from the housing rear wall to the housing opening.
• the diameter of the rollers can increase towards the housing rear wall.
• the inclination of the guide rails or the line is about 1 °.
• the seals comprise the strips or the rollers with a cross-sectionally c-shaped region.
• the elasticity of the seals is increased, whereby the operating forces decrease.
• edge projections are formed by wedge-shaped, with respect to the rest of the washing container outwardly directed to the housing side walls Spül intuitioner-side wall sections.
• the washing container can be manufactured as an injection molded part, a separate attachment of the edge approaches is eliminated.
• the inclination of the guide rails or the line is about 1 °.
• the seals project beyond the upper edge of the washing container with a molded sealing lip. This prevents liquid from passing over the edge of the washing container during the washing operation and then dripping into the housing when the washing container is extended. By connecting such a labyrinth in front of the main density plane, safety is increased.
