The pamphlet DE 10 2013 211 554 A1 discloses a pull-out system for a dishwasher, with a guide rail, which is configured to mount a receptacle for items to be washed in relation to a washing container of the dishwasher so that it can be displaced between an extended and pushed-in state, the guide rail also being configured to move when the receptacle is displaced for items to be washed around their longitudinal axis between the extended and the inserted state. The guide rail can have a link guide which interacts with a link for rotating the guide rail. Furthermore, the link guide can point downwards in the inserted state of the receptacle for items to be washed. Furthermore, the guide rail can be designed as a tube and / or the link guide can be designed as a slot. In addition, at least one roller can be guided in the guide rail.

Against this background, it is an object of the invention to provide an improved domestic dishwasher.

Accordingly, a household dishwasher is proposed with a washing container, a guide device and a washware receptacle, which can be displaced out of and into the washing container of the household dishwasher with the help of the guide device having a running rail, the guide device being first rollers which are rotatably attached to the washing container and which are preferably arranged within the running rail, and second running rollers which are rotatably attached to the washware receptacle, wherein the first rollers and the second rollers roll in or on the running rail when the washware receptacle is moved out of the wash container and when the washware receptacle is moved into the wash container, and the guide device has a locking element which is designed to hold the washware receptacle when it is moved out to fix the same from the rinsing container on the running rail. The fixation continues until the running rail is completely displaced out of the washing container. The locking element has a stop section on which one of the first rollers strikes in order to release the washware receptacle. The locking element is designed to release the washware receptacle when the running rail is completely displaced out of the washing container, in order to bring the washware receptacle itself into a state completely displaced out of the washing container.

The washware receptacle can therefore be moved out of the wash container in two stages in particular. In a first stage, only the running rail is moved, with the washware receptacle being fixed on the running rail. In a second step, the wash ware holder is released and moves along the running rail, while the running rail itself is stationary. Because the rails of two guide devices of a washware receptacle are always first moved synchronously out of the washing compartment, a constantly low pull-out force can be achieved, since the washware receptacle cannot tilt when it is moved out of the washing compartment. Furthermore, by fixing the washware receptacle on the running rail, a jolt-free and wobble-free displacement of the washware receptacle out of the washing compartment is ensured.

The state of the running rail displaced completely out of the washing container is defined as a state from which the running rail cannot be displaced further out of the washing container. In particular, in this state a roller of the guide device rests against an end cap of the running rail. In the state of the running rail displaced completely out of the washing container, however, it can still be partially located inside the washing container. The state of the washware receptacle that is completely displaced out of the washing container is defined as a state from which the washware receptacle cannot be displaced further out of the washing container. In particular, the washware receptacle is completely out of the washing compartment The displaced state is arranged completely outside the washing compartment so that it can be conveniently loaded and unloaded.

There are preferably two first rollers which are rotatably attached to a mounting plate. The fastening plate is fastened to a side wall of the washing container, for example screwed, riveted or welded to it. The guide device has three second rollers, two of the second rollers rolling on the top side of the running rail and one of the second running rollers rolling on the underside of the running rail.

The second rollers are preferably arranged outside the guide rail. The guide rail is preferably made of a metal material. The rollers can be made of a plastic material. The running rail is C-shaped in cross section.

The stop section is passed through an opening provided in the running rail. As a result, the locking element, which is preferably designed as an end cap, can be positively connected to the running rail. When the running rail is displaced out of the washing container, it is displaced out of it until one of the first running rollers strikes the stop section. When the washware receptacle is pulled further out of the washing container, the running rail no longer moves, but the locking element releases the second roller, which then rolls on the running rail in order to move the washware receptacle completely out of the washing container.

According to a further embodiment, the locking element for fixing the washware receptacle when it is displaced out of the washing compartment on the running rail is designed to grip around one of the second running rollers in a form-fitting manner.

The second running rollers preferably have a concave running surface. The locking element is designed to engage in the concave running surface.

According to a further embodiment, the locking element has a resiliently deformable encompassing section for positively engaging around the second roller.

The encompassing section is preferably made of a resiliently deformable material, in particular plastic.

According to a further embodiment, the encompassing section is designed to grip around a running surface of the second running surface at least in sections.

As already mentioned above, the second running surface has a concave running surface into which the encompassing section engages. Furthermore, the roller has two flanks arranged opposite one another.

According to a further embodiment, the encompassing section is arc-shaped, in particular circular arc-shaped, curved and preferably brush-shaped.

The geometry of the encompassing section can be used to set a fixing force which has to be overcome when pulling the washware receptacle out of the wash container.

The encompassing section preferably has a multiplicity of bristles which extend in the direction of the running surface of the second running roller. The bristles are resiliently deformable.

According to a further embodiment, the encompassing section is set up to engage laterally in a flank of the second roller.

The encompassing section is preferably designed to engage the flank of the second roller in a form-fitting manner.

According to a further embodiment, the locking element comprises two encompassing sections which are designed to engage the flank of the second roller on both sides.

As a result, a force which is required to release the second roller can be increased.

According to one embodiment, the locking element for fixing the washware receptacle when it is shifted out of the washing container on the running rail has at least one preferably resilient element which is designed to at least partially engage behind an undercut formed on the washware receptacle in a form-fitting manner.

A locking element in the form of a preferably resilient element, which is designed to at least partially engage behind an undercut formed on the washware receptacle in a form-fitting manner, provides the advantage of an identical part for the left guide device and for the right guide device. Furthermore, it does not have any significantly protruding parts, so that the locking elements are prevented from getting caught in one another during transport and thus transport in loose containers is possible. There is also the possibility of a simpler assembly of the locking elements and the risk of damage to a locking element is largely avoided. The locking element does not come into any direct contact with the roller, so that a possible disadvantage due to the contact due to the non-contact is completely avoided.

According to one embodiment, the undercut is formed or formed on a device for adjusting the height of the washware receptacle, on a contour of the washware receptacle or by a preferably vertical basket wire of the washware receptacle.

The locking element, in the form of a preferably resilient element, can in principle act on the washware receptacle, an additional assembly of the washware receptacle or even an additional part of the washware receptacle, in particular engage behind it. With regard to construction, functionality, operational safety and costs, it is advantageous to use an undercut on a device for adjusting the height of the washware receptacle, on a contour of the washware receptacle or on a preferably vertical basket wire of the washware receptacle.

According to a further embodiment, the locking element is pushed onto an end section of the guide rail and connected to it in a form-fitting manner.

Preferably, an opening is provided on the end section, into which the stop section of the locking element engages in a form-fitting manner.

According to a further embodiment, the locking element is a one-piece plastic component, in particular a plastic injection-molded component.

As a result, the locking element can be manufactured inexpensively in large numbers.

According to a further embodiment, the domestic dishwasher comprises two guide devices which are provided on opposite side walls of the washing container.

The guide devices are preferably connected to the side walls with the aid of the first rollers. The first rollers are rotatably connected to fastening plates, which in turn are screwed, riveted or welded to the respective side wall of the washing container.

According to a further embodiment, the domestic dishwasher comprises several washware receptacles, two guide devices being assigned to each washware receptacle.

For example, the household dishwasher can have three washware receptacles, in particular a lower basket, an upper basket and a cutlery drawer, with each of these washware receptacles being able to be assigned two such guide devices.

Further possible implementations of the household dishwasher also include combinations, which are not explicitly mentioned, of features or embodiments described above or below with regard to the exemplary embodiments. The person skilled in the art will also add individual aspects as improvements or additions to the respective basic shape of the household dishwasher.

Further advantageous configurations and aspects of the domestic dishwasher are the subject matter of the subclaims and of the exemplary embodiments of the domestic dishwasher described below. In the following, the domestic dishwasher is explained in more detail on the basis of preferred embodiments with reference to the enclosed figures.

In the figures, elements that are the same or have the same function have been given the same reference symbols, unless otherwise stated.

The Fig. 1 shows a schematic perspective view of an embodiment of a household dishwasher 1. The household dishwasher 1 comprises a washing container 2, which can be closed by a door 3, in particular watertight. For this purpose, a sealing device can be provided between the door 3 and the washing container 2. The washing container 2 is preferably cuboid. The washing container 2 can be arranged in a housing of the domestic dishwasher 1. The washing compartment 2 and the door 3 can form a washing chamber 4 for washing items to be washed.

Door 3 is in the Fig. 1 shown in their open position. The door 3 can be closed or opened by pivoting about a pivot axis 5 provided at a lower end of the door 3. With the aid of the door 3, a loading opening 6 of the washing compartment 2 can be closed or opened. The washing compartment 2 has a floor 7, a ceiling 8 arranged opposite the floor 7, a rear wall 9 arranged opposite the closed door 3 and two side walls 10, 11 arranged opposite one another. The floor 7, the ceiling 8, the rear wall 9 and the side walls 10, 11 can for example be made of a noble steel sheet. Alternatively, for example, the bottom 7 can be made of a plastic material.

The domestic dishwasher 1 also has at least one washware receptacle 12 to 14. Preferably, several, for example three, washware receptacles 12 to 14 can be provided, the washware receptacle 12 being a lower washware receptacle or a lower basket, the washware receptacle 13 an upper washware receptacle or an upper basket and the washware receptacle 14 a cutlery drawer. As the Fig. 1 Farther shows, the washware receptacles 12 to 14 are arranged one above the other in the washing container 2. Each washware receptacle 12 to 14 can optionally be moved into or out of the wash container 2. In particular, each washware receptacle 12 to 14 can be pushed into the washing container in an insertion direction E (arrow) and pulled out of the washing container 2 in a pull-out direction A (arrow) counter to the insertion direction E (arrow). In order to move out and in the washware receptacles 12 to 14, each washware receptacle 12 to 14 can have two in the Fig. 1 be assigned guide devices not shown.

The Fig. 2 shows a schematic side view of an embodiment of a guide device 15 for the washware receptacle 13. However, the guide device 15 is also suitable for the washware receptacles 12 or 14. In the following, however, only the washware receptacle 13 will be discussed. The washware receptacle 13 is assigned two such guide devices 15, which are fastened to the mutually opposite side walls 10, 11 of the wash container 2. The guide device 15 has two first rollers 16, 17. The number of first rollers 16, 17 is arbitrary. However, at least two such first rollers 16, 17 are provided. The first rollers 16, 17 are rotatably attached to the washing container 2, in particular to one of the side walls 10, 11. For this purpose, a fastening plate can be provided on which the first rollers 16, 17 are rotatably mounted. The fastening plate is then screwed, welded or riveted to one of the side walls 10, 11. That is, the first rollers 16, 17 are fixed in place in the washing container 2.

The guide device 15 further comprises a running rail 18 which is C-shaped in cross section. The first rollers 16, 17 are arranged in the running rail 18. The running rail 18 can be pulled out of the washing container 2 in the pull-out direction A (arrow) and pushed into the washing container 2 in the insertion direction E (arrow), the first rollers 16, 17 rolling in the running rail 18. The running rail 18 has a first end section 19 and a second end section 20 facing away from the first end section 19.

An end cap 21, which closes the first end section 19 on the front side, is pushed onto the first end section 19. Preferably, the end cap 21 is positively connected with connected to the first end section 19. A positive connection is created when at least two connection partners interlock or engage behind one another. The end cap 21 can have snap hooks, for example, in order to connect it to the first end section 19. The end cap 21 has a closure section 22 which is arranged inside the running rail 18 and which serves as a stop, that is to say as an end position, for one of the first running rollers 16, 17, in particular for the first running roller 16. Furthermore, the end cap 21 has an end section 23 which projects upwards over the running rail 18 and which can be curved, in particular curved in the shape of a circular arc.

A further end cap, in particular a locking element 24, of the guide device 15 is provided on the second end section 20 of the running rail 18. That in the Fig. 3 The locking element 24 shown is preferably a one-piece plastic component, in particular a plastic injection-molded component. The locking element 24 is pushed onto the second end section 20 of the running rail 18 and connected to it in a form-fitting manner. For this purpose, an opening 25 can be provided on the second end section 20 of the running rail 18, into which a stop section 26 of the locking element 24 engages in a form-fitting manner.

The locking element 24 comprises a base body 27 which, like the running rail 18, has a C-shaped cross section. The base body 27 has two opposing, mirror-inverted arches 28, 29, which are connected to one another on one side by a closed wall 30. The base body 27 has an opening 31 on the other side. With the opening 31, the locking element 24 can be snapped onto the second end section 20 of the running rail 18.

The stop section 26 protrudes from the wall 30 on the front side, that is to say in the direction of the opening 31. The base body 27 also has a rear wall 32, on which the second end section 20 of the running rail 18 rests in the assembled state of the guide device 15. Opposite the rear wall 32, the base body 27 is open. On the outside of the base body 27, two ribs 33, 34 which are arranged in mirror image to one another and are T-shaped are provided. One of the ribs 33 extends a resiliently deformable encompassing section 35 out. The encompassing section 35 is curved in the shape of an arc, in particular in the shape of a circular arc.

Now returning to that Fig. 2 the guide device 15 further comprises a plurality of second rollers 36 to 38. With regard to a direction of gravity g (arrow), two second rollers 36, 37 are arranged above the running rail 18 and are set up to roll on the running rail 18, and one of the second running rollers 38 is in relation to the Direction of gravity g (arrow) arranged below the running rail 18. In contrast to the first running rollers 16, 17, the second running rollers 36 to 38 are not arranged inside the running rail 18, but rather outside the running rail 18. Two second rollers 36, 37 are set up to roll on an upper side 39 of the running rail 18, and one of the second running rollers 38 is set up to roll on an underside 40 of the running rail 18.

The second rollers 36 to 38 are rotatably fastened to a fastening plate 41. The fastening plate 41 is in turn connected to the washware receptacle 13. That is, the second rollers 36 to 38 are coupled to the washware receptacle 13 via the fastening plate 41. Furthermore, a height adjustment is provided which has an actuating lever 42 with the aid of which the washware receptacle 13 can be moved upwards in relation to the running rail 18 against the direction of gravity g (arrow) or downwards in the direction of the direction of gravity g (arrow). In this way, the washware receptacle 13 can be adapted to the height of the washware to be washed.

The Fig. 2 shows the running rail 18 in an initial state displaced completely into the washing container 2, in which the first running roller 16 rests against the end cap 21 and the second running roller 37 rests against the rib 33. In this initial state, the second roller 37 is encompassed by the encompassing section 35 of the locking element 24, at least in sections. The encompassing section 35 is arranged in such a way that it encompasses the second roller 37 in the middle of its diameter, a looping angle being freely selectable depending on the required holding force.

The mode of operation of the guide device 15 is explained below with reference to FIG Figures 2 to 9 explained. Based on the one in the Fig. 2 initial state shown, in which the first roller 16 rests against end cap 21 and second roller 37 is encompassed by encompassing section 35 of locking element 24, washware receptacle 13 is displaced out of washing container 2 in pull-out direction A (arrow). The first rollers 16, 17 run, as in the Figures 4 and 5 shown, from the inside in the running rail 18. The second roller 37 is, as in FIG Fig. 5 shown, as before, encompassed by the encompassing section 35. This means that when the washware receptacle 13 is moved out of the washing container 2 in the pull-out direction A (arrow), the first rollers 16, 17 initially run off the inside of the running rail 18, which moves the latter together with the washware receptacle 13 out of the wash container 2. In this case, however, the second running rollers 36 to 38 do not yet roll on the upper side and the lower side on the running rail 18, since the second running roller 37 is locked with the aid of the encompassing section 35. The second rollers 36 to 38 have a concave running surface 43 into which the encompassing section 35 engages. In the Figures 4 and 5 the running rail 18 is in an intermediate state between the initial state and a state that has been completely displaced out of the washing container 2.

If the washware receptacle 13 is moved further out of the washing compartment 2, as in FIG Figures 6 and 7 shown, the first roller 17 on the stop portion 26 of the locking element 24 on. The state in which the first roller 17 rests against the stop section 26 represents a state of the running rail 18 that has been completely displaced out of the washing container 2. That is to say, the running rail 18 can be moved from the into the Figures 6 and 7 The completely displaced state shown cannot be pulled further out of the washing container 2 in the pull-out direction A (arrow).

If a further pull-out force is nevertheless applied to the washware receptacle 13, it is deformed, as in FIG Fig. 7 shown, the encompassing portion 35 of the locking element 24 resiliently, whereby the second roller 37 is released. The washware receptacle 13 can now be pulled completely out of the washing container 2 in the pull-out direction A (arrow), the second rollers 36 to 38 rolling on the top and bottom of the running rail 18. The upper washware receptacle 13 can be pulled out of the washing container until the second roller 36 comes into contact with the end section 23 of the end cap 21.

The Figures 8 and 9 show the displacement of the washware receptacle 13 into the washing compartment 2 in the insertion direction E (arrow). When the washware receptacle 13 is shifted into the washing container 2, the first rollers 16, 17 roll on the inside on the running rail 18, and the second running rollers 36 to 38 roll on the top and bottom of the running rail 18. The running rail 18 is pushed into the washing compartment 2 until the first roller 16 strikes the end cap 21. When the washware receptacle 13 is pushed further into the washing container 2 in the direction of insertion E (arrow), the encompassing section 35 of the locking element 24 is resiliently deformed, whereby it again encompasses the second roller 37 in a form-fitting manner and fixes the washware receptacle 13 on the running rail 18.

The Figures 10 and 11 show a further embodiment of a locking element 24. In this embodiment of the locking element 24, this has two encompassing sections 35, 35 ', which are designed to engage positively on both sides in a flank 44, 45 of the second roller 37.

The Figures 12 and 13 show a further embodiment of a locking element 24. The locking element 24 according to FIGS Figures 12 and 13 differs from the locking element 24 according to FIGS Figures 10 and 11 in that this has only one encompassing section 35 which is set up to engage laterally in one of the flanks 44, 45 of the second roller 37 in a form-fitting manner.

The Figures 14 and 15 show a further embodiment of a locking element 24. In this embodiment of the locking element 24, the latter comprises two encompassing sections 35, 35 'which encompass the second roller 37 laterally.

The Figures 16 and 17 show a further embodiment of a locking element 24. The embodiment of the locking element 24 according to FIGS Figures 16 and 17 differs from the embodiment of the locking element 24 according to FIGS Figures 14 and 15 only in that the locking element 24 has only one encompassing section 35 which laterally encompasses the second roller 37.

The Figures 18 and 19 show a further embodiment of a locking element 24. In this embodiment of the locking element 24, the encompassing section 35 is designed in the shape of a brush and engages in the running surface 43 of the second roller 37.

The Fig. 20 shows a schematic perspective view of a further embodiment of a locking element 24 for the guide device 15 according to FIG Fig. 2 .

At the second end section 20 of the running rail 18 (cf. Fig. 2 ) is a further end cap, in particular a locking element 24 for fixing the washware receptacle 12 to 14 when it is moved out of the wash container 2 (cf. Fig. 1 ), provided on the guide device 15. The locking element 24 is preferably a one-piece plastic component, in particular a plastic injection-molded component. The locking element 24 is pushed onto the second end section 20 of the running rail 18 and connected to it in a form-fitting manner. For this purpose, an opening 25 can be provided on the second end section 20 of the running rail 18, into which a stop section 26 of the locking element 24 engages in a form-fitting manner (cf. Fig. 3 ).

The locking element 24 comprises a base body 27 which, like the running rail 18, has a C-shaped cross section. The base body 27 has two opposing, mirror-inverted arches 28, 29, which are connected to one another on one side by a closed wall 30. On the other side, the base body 27 has an opening 31 (cf. Fig. 3 ) on. With the opening 31, the locking element 24 can be snapped onto the second end section 20 of the running rail 18.

The locking element 24 has at least one resilient element 46, which is designed to have an undercut 47 formed on the washware receptacle 12 to 14 (cf. Figures 21 and 22 ) to reach behind at least partially in a form-fitting manner. The resilient element 46 has an essentially tongue-like basic contour 51 and is attached to one side of the base body 27. In the area of the essentially tongue-like basic contour 51 of the resilient element 46 facing away from the base body 27, an elevation 52 is attached which causes the undercut 47 formed on the washware receptacle 12 to 14 to reach behind depending on the position of the washware receptacle 12 to 14.

The stop section 26 protrudes from the wall 30 on the front side, that is to say in the direction of the opening 31. The base body 27 also has a rear wall 32, on which the second end section 20 of the running rail 18 rests in the assembled state of the guide device 15. Opposite the rear wall 32, the base body 27 is open. On the outside of the base body 27, two ribs 33, 34 which are arranged in mirror image to one another and are T-shaped are provided.

The two Figures 21 and 22 each show a schematic plan view of the further embodiment of the locking element 24 for the guide device 15 according to FIG Fig. 20 . In the representation of the Fig. 21 the washware receptacle 12 to 14 is in a freely movable position, whereas it is in the Fig. 22 is in a locked position (end position) that is engaged behind.

The undercut 47, which the elevation 52 of the resilient element 46 of the locking element 24 can at least partially engage behind in a form-fitting manner, is preferably on a device 48 for adjusting the height of the washware receptacle 12 to 14, on a contour 49 of the washware receptacle 12 to 14 or by a preferably vertical basket wire 50 of the items to be washed 12 to 14 are formed or formed. Since the respective element 48, 49, 50 provided with the undercut 47 is known to the person skilled in the art, it is only shown schematically.

The main advantage of the guide device 15 is that it is ensured that the running rails 18 of two guide devices 15 assigned to the washware receptacle 13 always move out of the washing container 2 synchronously first. In this way, constantly low pull-out forces are achieved, since the washware receptacle 13 cannot jam when it is moved out of the wash compartment 2. Furthermore, by holding the second castors 37 on the washware receptacle 13, a jerky or wobbly pulling out of the washware receptacle 13 is reduced until the second castor 37 is released.

Although the present invention has been described on the basis of exemplary embodiments, it can be modified in many ways.
