Description

The The invention relates to a household appliance, in particular a dishwasher, according to the preamble of claim 1.

Of the Transportation or stacking of household appliances, such as a dishwasher can factory done by means of a so-called staple stacker, the outside Clamping forces on opposing housing sides of the household appliance and relocate the parenthesized appliance accordingly.

The exerted by the stapler clamp forces be over the sides of the housing through the inside of the housing of the household appliance directed. In a generic household appliance is a Useful space-container in particular a washing container of a dishwasher, intended. The work space container has at least one connecting flange, on which angled margins of adjacent container side walls with each other welded are. With the connecting flange, the container side walls are liquid-tight connectable. The connection flange can also the work space container move almost completely, whereby it increases the dimensional stability of the work space container in a double function.

The on the household appliance applied clamping forces are to be dimensioned so that there is no container destruction. Besides that is known, to relieve the Nutzraum container another force path to provide over the clamping forces outside of the work space container through the household appliance be directed. This is done by way of example via an additional Wooden slat, a cardboard roll or a plastic strip, between the connected to both lateral Kraftaufnehmerelementen.

The The object of the invention is a household appliance, in particular a dishwasher, to provide with a dimensionally stable work space container, in particular in a simple way the clamping forces with transporting or stacking the household appliance withstands.

The The object is solved by the features of claim 1. preferred Further developments of the invention are disclosed in the subclaims.

The Invention gehr from a household appliance with a Nutzraum-container, in particular a rinse tank one Dishwasher, the at least one connecting flange, on the side edges of Container side walls to each other are connected.

According to the invention, it is provided the connecting flange has at least one force introduction element. This is the dimensional stability the connecting flange and thus the entire working space container against external loads, such as the outer clamping forces increased. Usually can the work space container one made of sheet metal walls manufactured stainless steel container be. The metal walls can at their angled margins welded together be and so form the connecting flange is preferably provided that at the connecting flange at least one force transducer element supported is over that from the outside on the household appliance applied clamp forces in the work space container can be introduced.

Besides that is preferably provided that the force introduction element at least a force introduction surface has, on which the force transducer element is supported.

Finally is preferably provided that the force introduction surface by a stiffening bead is formed of the connecting flange.

The Stiffening bead can be exemplified in a molding process in the connecting flange are introduced and approximately transversely extend to the connecting flange.

At the Connecting flange are therefore the angled side edges adjacent Container side walls with each other connected, in particular welded. The thus approximately at right angles to Container sidewall outward protruding connecting flange therefore not only connects container side walls, but elevated also the inner stability of the work space container. Consequently, the connecting flange can be used as a suitable abutment for a Force transducer element serve over that from the outside on the household appliance applied clamp forces in the work space container can be initiated.

For safe handling by the stapler, sufficiently large clamping forces are required. On the other hand, it must be ensured that there is no container destruction due to excessive clamping forces. Against this background, it is particularly relevant to increase the number of force application points of the force transducer element in the connecting flange. According to a preferred embodiment, the stiffening bead can provide a first force introduction surface, on which the force transducer element can be supported when a clamping force is exerted. The stiffening bead thus not only increases the dimensional stability of the useful space container, but at the same time also the number of force application points on the Nutz space containers.

Of the Connecting flange of the work space container can be along margins at least two adjacent container walls extend. Especially forms the connecting flange between laterally opposite Force transducer elements a device internal force path for passing the clamping forces. The connecting flange can be at its opposite Sites have at least one such stiffening bead. By the stiffening bead provided force application surface can slanted in the manner of a start-up ramp be. When exercising Therefore, the force transducer element can be a force component of a clamping force produce, which the force transducer element against another force introduction of the Useful volume container depressed becomes. Here it makes sense that the force transducer element immediately on the outside of the work space container is pressed. The stiffening bead therefore sets itself in a double function Krafteinleitfläche and pushes at the same time the force transducer element against the further force introduction surface on the useful space container.

When third force introduction surface can be an outer edge act of the connecting flange against which known the Force transducer element during exercise supported by a clamping force can be.

Prefers can be at the opposite, preferably rearward corner areas of the work space container in each case a force transducer element may be provided. In both rear, upper corner regions of the usable space container, in particular the dishwashing rinse tank, run the back wall, the top wall and the respective side wall together. The back upper corner portions of the washing compartment are Therefore geometrically conditioned dimensionally stable and therefore particularly suitable for one greater force application from outer clamp forces of a Clamp truck. The at least one stiffening bead according to the invention may therefore be preferred in the area between the two upper rear Corners of the washing compartment to further increase the dimensional stability be provided.

Prefers can the outer clamping forces immediately be initiated in the stiffening bead. For this it is advantageous if the stiffening bead each close to the respective Kraftaufnehmerelement brought is.

Therefore, according to the invention ensures that the introduced by the stapler loaders as possible wide-ranging distributed on the work space container be applied.

The on the connecting flange of the useful space container attachable force transducer element can be a slot-like guide groove have, with the force transducer element approximately positively on the connecting flange of the work space container is pluggable. In the respective side walls of the guide groove of the Kraftaufnehmerelementes can be at least one bag-shaped Recess may be provided, which adapted to the shape of the stiffening bead is. The force transducer element can therefore with its guide with more or less big Mounting clearance in positive engagement with the connecting flange as well the stiffening bead.

The Kraftaufnehmerelement is preferably a plastic part, the at exercise of braces yielding deformable. As a result, despite tolerance-related dimensional deviations the Kraftaufnehmerelements or the Nutzraum container all force introduction surfaces of the Useful volume container in pressure plant with the corresponding abutment surfaces of the Kraftaufnehmerelmentes come. Against this background, it is in particular of Advantage, if the stiffening bead in approximately semi-cylindrical in Connecting flange is formed. For tolerance-related dimensional deviations can therefore upon application of force corresponding abutment surfaces of Kraftaufnehmerelementes at least slightly from the semi-cylindrical shaped Stiffening bead are elastically yielding deflected, causing also the other abutment surfaces of Kraftaufnehmerelementes in full-scale printing system with the usable space container can be brought are.

following is an embodiment the invention with reference to the attached Figures described.

It demonstrate:

1 in a perspective view from behind a dishwasher with exposed cover and rear wall of the outer housing of the dishwasher;

2 in an enlarged perspective view, a rear side upper corner portion of the washing container;

3 the device-rear upper corner region of the washing container with only dash-dotted lines indicated Kraftaufnehmerelement; and

4 in a perspective view from below a force transducer element.

In the 1 is a rear perspective view of a dishwasher with a washing container 1 shown. The washing container 1 is be kannterweise made of stainless steel sheet and has a front loading port, not shown, on. Its top wall 3 as well as back wall 5 are in the 1 for the sake of clarity exposed exposed. The washing container 1 is therefore in the 1 in one only by the two side walls 7 arranged outer housing arranged.

The washing container 1 Here, by way of example, has a box-shaped, ring-like closed metal jacket with a rectangular cross section, which covers the top wall 3 , the side walls 4 and the bottom wall of the washing container, not shown 1 forms. At its back, the box-shaped metal jacket by the approximately trough-shaped rear wall 5 closed. The open front of the box-shaped sheet metal jacket is in a known manner by a U-shaped front frame 6 limited.

The box-shaped, ring-like closed metal jacket and the rear wall 5 of the washing container 1 according to the 2 at their mutually facing edge zones 9 . 11 outwards at right angles angled side edges 12 . 13 on, which are interconnected by a roller seal, not shown, and together a connecting flange 14 form. The connecting flange 14 can be used as a connection point between the metal jacket and the rear wall 5 on the entire side the entire washing container 1 frame.

In the 2 is a device rear, upper corner of the washing compartment 1 shown on the back wall 5 , the top wall 3 as well as one only in the 3 shown side wall 4 of the washing container 1 converge. To initiate lateral clamping forces F _K by means of a stapler used in the factory are according to the 1 and 2 at these rear, upper corner areas of the washing compartment 1 each lateral Kraftaufnehmerelemente 17 intended. These cover each corner areas and are between the washing 1 and the respective device side wall 7 is switched. Both rear load cell elements 17 are over in the depth direction x aligned lateral Kraftaufnehmerschienen 19 with front load cell elements 21 coupled. These are in lateral contact with the U-shaped front frame 6 of the washing container 1 ,

In the 3 is a rear upper corner of the washing container 1 shown in isolation, while the applied thereon Kraftaufnehmerelement 17 only indicated by dash-dotted lines. Consequently, in the horizontal section of the connecting flange 14 stiffening beads arranged one behind the other 23 provided, which are approximately semicylindrical than pocket-shaped recesses in the connecting flange 14 are formed. According to the 3 is the top wall side edge 12 to the backside side edge 13 herumgebördelt. In the area of this flange is therefore the connecting flange 14 three-layered.

The two stiffening beads 23 are according to the 3 slanted in the manner of a start-up ramp, that is, the stiffening beads 23 run according to the 3 in the device side direction y outward obliquely upward. The respective exterior surface facing the device segments 25 the two stiffening beads 23 in each case provide first force introduction surfaces, against which when exercising the clamping force F _K Kraftaufnehmerelement 17 suppressed.

Like from the 3 further shows, the two semi-cylindrical stiffening beads 23 in the device depth direction x oriented in opposite directions, thereby simultaneously the dimensional stability of the connecting flange 14 is increased. As a further force introduction surface 27 is according to the 3 the outer edge of the vertical portion of the connecting flange 14 provided here the back wall 5 with the sidewall 4 combines.

In the 4 is a force transducer element 17 shown in isolation. The force transducer element 17 is manufactured as a plastic component by injection molding. On its underside, in the installation position the washing container 1 facing, has the force transducer element 17 a roughly truss-like structure. The truss-like structure is centered by a slot-like guide groove 29 divided, with the force transducer element 17 in the upper Spülbehälter corner area positively on the connecting flange 14 is pluggable. In the two side walls 31 the guide groove 29 of the force transducer element 17 are pocket-shaped recesses 33 provided the stiffening beads 23 are contour-matched.

For the transport or stacking of the dishwasher by means of a so-called staple stacker, the clamping forces F _K on the housing side walls 7 the dishwasher applied, as it is in the 1 is indicated. By the applied clamping forces F _K are the laterally opposite force transducer elements 17 pressed with their abutment surfaces against the force input surfaces of the washing. As an abutment surface according to the invention acts according to the

4 the groove bottom 35 the guide groove 29 of the force transducer 17 , The groove bottom 35 presses against the vertical outer edge 27 of the connecting flange 14 ,

The slanted circular surface segments 37 the two stiffening beads 23 serve just if as abutment surfaces, against the force introduction surfaces 25 the two stiffening beads 23 be pressed. Because the two force introduction surfaces 25 the stiffening beads 23 are tilted in the manner of a start-up ramp, when exercising the clamping force F _K on the Kraftaufnehmerelement 17 generates a vertical force component F _V , as shown in the 1 is indicated. With the force component F _V is the force transducer element 17 down to the outside of the ceiling wall 3 pressed, which acts as a further force introduction surface.

Overall, therefore, with the outside of the ceiling wall 3 , the force introduction surfaces 25 the stiffening beads 23 as well as with the outer edge 27 of the connecting flange 14 provided over a wide distributed Krafteinleiftlächen that when exercising the clamping forces F _K voltage peaks in the two corners of the washing compartment 1 reduce and thereby a deformation of the washing container 1 prevent.
