Description

Dishwasher for installation in a sidewall-limited installation space of a built-in cabinet, with a mounting portion, which is intended to be arranged in the installation space, and with a door for closing a feed opening, wherein the door about a arranged at a lower portion of the feed opening horizontal axis in a Pivoting range between a closed position and an open position is pivotable, and wherein the door projects beyond the mounting portion in its width, so that the door obscured in its closed position at least a part of an end face of the respective side wall of the built-in cabinet when properly installed dishwasher.

Dishwashers usually have a loading opening for loading and unloading, which can be closed by a door arranged on a front side. In a closed position, the door is substantially vertical, in an open position substantially horizontally aligned. To open the door is usually pivoted about a horizontal axis. The term "axis" is to be understood in particular as a straight line around which the rotational or pivotal movement of the door takes place.

Standard dishwashers, which are designed as a stand-alone unit or as an under-unit, have a door whose width corresponds to the body of the dishwasher. Now, if such a standard dishwasher placed in a kitchenette between two cabinets, the door for opening and closing can be easily pivoted about the horizontal axis, since the distance of the adjacent cabinets is greater than the width of the door.

In a dishwasher, which is intended for installation in a built-in closet, there is the problem that the available installation space in the direction of the width of the dishwasher is limited by the inner sides of the side walls of the built-in closet. However, it is desired that the dishwasher inserts in a front view in the appearance of the kitchenette, which means in particular that the front elements of the front sides of the To cover side walls. This means that front elements must have a width which is greater than that portion of the dishwasher, which is provided for installation in the space defined by the side walls cuboid installation space of the built-in closet.

In known dishwashers for installation in a built-in wardrobe, the width of the door, which is provided for closing the loading opening, adapted to the width of the mounting portion, so that the door between the side walls of the built-in wardrobe can be moved. In order to achieve an even front, which also covers the end faces of the side walls, a front door is arranged in front of the actual door, which covers the end faces. This front door is pivotable about a second axis. The actual door and the front door are connected to each other via a lever arrangement, so that when the intent door is opened, and the actual door of the dishwasher is moved to its open position. Such tow door solutions are complex and therefore expensive.

In other known dishwashers for installation in a built-in closet was therefore dispensed with attachment doors. In order to cover the end faces of the side walls of the built-in closet in the region of the door, the door of such a dishwasher dominates the installation section in its width. The door is designed so that it covers a substantial portion of the width of the end faces of the side walls when properly installed dishwasher in its closed position, the cover along its vertical extent, ie from its lower end to its upper end, provided on both sides is.

In such, also known from practice dishwashers for installation in a built-in cupboard, the axis is arranged to open and close the door to a movable lever assembly, so that the axis is moved when opening or closing the door, so changes their local position. However, such elaborate hinge solutions are complicated and therefore expensive.

From the EP 1 216 643 A1 is a dishwasher known which can be integrated into a kitchen equipped with other household appliances and furniture. This dishwasher has adjustable feet that touch the kitchen floor and a base recess. This is at the from the EP 1 216 643 A1 known dishwasher to a sub-unit, which is not suitable for installation in a built-in wardrobe.

Object of the present invention is to provide a dishwasher for a built-in wardrobe, in which the disadvantages mentioned are avoided. In particular, the structural design of a dishwasher should be simplified.

According to the invention, this object is achieved in a dishwasher of the type mentioned above in that the axis is arranged stationary, wherein the arrangement of the axis and the formation of the door are coordinated such that the mounting portion in the lateral direction superior part of the door Pivoting the door in the entire pivoting range is moved on a side facing away from the mounting portion of a boundary plane, which limits the mounting portion on the side of the feed opening.

In this way, a collision of the projecting part of the door with the end faces of the side walls of the built-in wardrobe is avoided in the entire pivoting range. At the same time the use of a fixed axis leads to a simplification of the structural design of the storage of the door. Another advantage of the fixed axis is that, compared to a pivoting away when opening the door axis, the door is placed in its open position closer to the mounting portion. This simplifies the sealing of the area between the installation section and the horizontally lying door, which is required in a dishwasher, to prevent water or dirt from dripping onto the kitchen floor between a door and an installation section located above the opened door.

According to an expedient development of the invention can advantageously be arranged below the door, a fixed base panel, the width of the Width of the door corresponds. In this way, a cover of the end faces of the side walls of the built-in closet in the region of the base of the dishwasher can be achieved in a simple manner.

In this case, it may be advantageous if the base panel rests against the front sides of the side walls when the dishwasher is installed as intended. The plinth panel thus additionally fulfills the function of a stop which simplifies the installation of the dishwasher in the built-in wardrobe. So in this case, the dishwasher must be inserted and fixed only in advance with their installation section in the closet. The correct installation depth does not have to be measured, but can be found in a simple manner by the dishwasher is pushed so far until the base panel rests against the front sides of the side walls.

In a further advantageous embodiment, when taking the closed position of the lower edge of the protruding part extends at the height of the axis or at a vertical distance above the axis. In this way it is achieved that no region of the projecting part when opening the door performs a pivoting movement in the direction of the mounting portion. This means at the same time that no part of the protruding part is moved in the direction of the end faces of the side walls when the dishwasher is installed. This makes it possible to design the door so that the protruding part rests closely against the side walls when the door is closed.

According to a further advantageous embodiment of the invention, when taking the closed position of the door, the vertical distance between the lower edge of the projecting part and the axis is preferably greater than the horizontal distance between the axis and the front of the base panel. In this way, it is possible in an advantageous manner that the plinth is pulled so far that it is located with the door open between the protruding part and the mounting portion. In this way, a small distance from door to plinth panel can be realized when taking the closed position of the door.

According to a further advantageous embodiment of the invention, the axis preferably extends on the side facing away from the mounting portion of the boundary plane. In particular, the axis is advantageously close to the lower edge of the projecting part, so that it is moved along a small circular arc during pivoting of the door. This favors the passing of the lower edge past fixed parts and further facilitates the sealing of the gap between the door and the installation section.

According to a further advantageous embodiment of the invention runs parallel to the axis extending lower edge of the feed opening on the side facing away from the mounting portion of the boundary plane. As a result, the task of sealing the space between the door and the installation section is at least partially taken over by a stationary element, which simplifies the structural design of the dishwasher in this area.

According to a further advantageous embodiment of the invention, the lower edge of the feed opening, i. the front, raised from the ground muzzle or skirt of the washing container, further from the boundary plane, as the axis of the door. This measure also contributes to a simplification of the seal in the transition region between the door and the installation section. In particular, therefore, the lower edge of the charging opening of the washing compartment is formed as a raised from the front bottom edge of the muzzle or skirt.

In particular, according to a further advantageous embodiment, the door has a cover section which, when the door is in the open position, covers the lower edge of the charging opening, in particular the raised container snout of the washing compartment, viewed from above. In this way it is ensured that water or dirt can not get through between the installation section and the door.

In particular, it can be particularly advantageous if the edge of the cover section runs in the open position located below the door opening of the feed opening. As a result, the inside of the wall, which forms the edge of the feed opening, protected from contamination when the door is open.

This is desirable because this area during operation of the dishwasher is not or only slightly with flushing water into contact, so that once adhering dirt would not be easily removed.

According to a further advantageous embodiment of the invention, the edge of the cover portion is guided during pivoting of the door along a portion of a floor pan whose surface extends in the manner of a lateral surface of a cylinder with a radius about the axis of the door. In this way, a consistently small distance of the edge of the fixed floor pan during pivoting can be realized. With a sufficiently small distance coarse contaminants are scraped at the section by the edge of the cover when closing the door. This favors self-cleaning of the affected area.

Preferably, the door is rectangular in a front view. On the one hand, this facilitates the production of the outside of the door, on the other hand results in a smooth front view, which fits well into the overall view of a fitted kitchen.

In particular, the invention provides a dishwasher particularly suitable for installation in a tall cabinet. 60 cm standard dishwashers will not fit in a tall cupboard, usually a cheek solution is preferred. When installed in a cabinet, the dishwasher is in particular a maximum of 56 cm wide, the door, however, about 59 cm. Therefore, the door can not swing into the cabinet. From the prior art tow door solutions or elaborate hinge solutions are known. In order to obtain a customer-friendly and simple solution, in particular the container leading edges of the dishwasher of the dishwasher and the door pivot point of the door are positioned in front of the cabinet front edges of the built-in wardrobe. The outer door of the door preferably ends just below the pivot point and the base is particularly firmly mounted on the device. Thus, the door can move in front of the cabinet sides or side walls of the built-in wardrobe, in particular in front of their end faces.

Other developments of the invention are given in the dependent claims. Variations and other combinations of features within the scope of the claims are readily possible.

The door 6 is pivotable with all its components about a fixed axis 10, which is arranged in the lower region 11 of the feed opening 5. In this case, the door 6 is pivotable from a closed position 6 via a pivoting area 12 into an open position 6 'and back. A bottom trough 13, which forms the lower portion of the washing container 4, is blinded by a base panel 14.

The dishwasher 1 is provided for installation in a built-in closet ES, in FIG. 2 is shown. An installation space ER provided for installation of the dishwasher is delimited at the top by a ceiling DE and at the bottom by a bottom BO. The installation space ER is further comprised by side walls SW, which in the representation of FIG. 2 parallel to the drawing plane. Another side of the installation space ER is covered by a rear wall RW. The remaining side is open, so that the dishwasher 1 can be inserted from this side into the installation space. The installation space ER is bounded on the open side by a plane in which the end faces or front sides STS of the side walls or side walls SW run. Overall, the installation space ER is preferably cuboidal. Above the installation space ER is another compartment of the built-in wardrobe ES is provided, which is closed by means of a door ST. Below the installation space ER is a third compartment of the built-in closet ES, which is closed by a further door ST. The installation space ER for the dishwasher is therefore provided here in the embodiment in a tall cabinet.

In FIG. 3 is the dishwasher 1 of FIG. 1 shown in the built-in wardrobe ES of the FIG. 2 is installed. The installation section 2 of the dishwasher is intended arranged in the installation space ER. Base skirt 14, outer door 7 and control panel 9, however, are arranged outside the installation space ER. The boundary plane 3 of the dishwasher 1 runs straight in the plane which limits the installation space ER at the open side of the built-in closet ES. Ie. the boundary plane 3 is in accordance with the purpose built dishwasher 1 at the end faces STS of the side walls SW of the built-in closet ES on. The strength of the control panel 9, the outer door 7 and the base panel 14 correspond substantially to the strength of the cabinet doors ST, in order to achieve a uniform front of the built-in wardrobe ES.

The door 6 has the part 7 'protruding over the installation section 2, which part is on the left side and another part on the right side of the outside door 7. The protruding part 7 'extends on both sides in each case from the lower edge of the front of the door 6 to its upper edge. By the towering part 7 ', the total width b2 of the door 6 is greater than the width b1 of the mounting portion 2. However, the base panel 14 also has the width b2 of the door 6. This results in a uniform, substantially rectangular front view of the dishwasher 1.

FIG. 5 shows the built-in wardrobe of FIG. 2 in a front view. The side walls SW have a width b3, which is for example 20 mm.

FIG. 6 shows a front view of the built-in closet ES dishwasher 1. In this illustration, it can be seen that each of the mounting sections overhanging parts in the lateral direction covers a substantial part of the width b3 of the respective front side or front side of the side walls SW of the built-in cabinet ES. In the vertical direction, the occlusion takes place along the outer door 7 and along the control panel 9.

FIG. 7 shows a detailed view of the dishwasher 1, wherein the area around the axis 10 is shown in a sectional view with the door 6 closed. The preferably made of sheet metal outer door 7 and also preferably made of sheet metal inner door 8 are connected in the illustrated area by means of a strut 15. As a result, a cavity is formed between the inner door 8 and the outer door 7, through which a lower edge 16 of the charging opening 5, that is, the front, raised from the ground container nose or apron of the washing 4 runs. This edge or container nose runs parallel to the axis 10 and is formed on the bottom trough 13. On the inner door 8, a cover 17 is formed, which covers the edge 16 in every possible position of the door 6. The edge 18 of the cover portion 17 extends at a small distance to a portion 19 of the bottom tray 13, whose surface extends in the manner of a lateral surface of a cylinder with a radius r about the axis 10.

In the first embodiment, the axis 10 is arranged above the lower edge of the outer door 7. Furthermore, it is arranged on the side facing away from the installation section 2 of the level 3. The outer door 7 does not lie with its the front sides of the built-in closet covering part directly on the side walls, but has a small distance of, for example, a few millimeters. In a pivoting movement of the door 6 for the purpose of opening it moves in the representation of FIG. 7 their lower edge in the direction of the installation section 2, but not beyond the level 3 due to the selected geometry. As a result, an opening and closing of the door is possible without the axis 10 is moved away when opening the door 6 of the mounting portion. The hinges of the door 6, not shown, can therefore be made particularly simple.

FIG. 8 shows a detailed view of the rotatably mounted suspension of the door of the dishwasher of FIG. 7 , wherein now the door 6 is in its open position 6 '. In this position, the lower edge 16 of the feed opening 5 through covered the cover portion 17 of the inner door 8. In this case, the edge 18 of the cover portion 17 extends below the lower edge 16 of the loading opening 5. As a result, contamination of the inside of the bottom tray 13 below the edge 16 is largely avoided. In the area of the portion 19 of the bottom pan 13 occurring dirt are scraped off by the edge 18 of the cover 17 when closing the door. In this way, a permanent contamination of the floor pan 13 is avoided in the area of the door with little or no flushing water.

FIG. 9 shows in a modification of the first embodiment of the FIGS. 7 . 8th a detail of a second embodiment of a dishwasher according to the invention 1. The main difference from the previous embodiment is that the lower edge 20 of the outer door 7 extends at a distance a1 above the axis 10. When pivoting the door for the purpose of their opening, therefore, the lower edge 20 moves away from the mounting portion 2. This makes it possible that the outer door 7 rests against the side walls SW in its closed state 6. A distance between the side walls and the outer door is not required in this embodiment. The vertical distance a1 is selected to be at least as large as the horizontal distance a2 between the axis 10 and the front side of the base panel 14. This makes it possible that the base panel 14 is pulled far up, so that between the closed door. 6 and the base panel 14 gives only a small distance. When opening, the outer door 7 pivots about the base panel, so that in the open state, the base panel 14 between the mounting portion 2 and the outer door 7 is located.
