Description

The invention relates to a household dishwasher according to the preamble of claim 1.

Dishwashers usually have a front door appliance, which is hinged about a horizontal bottom-side pivot axis. The appliance door can be provided with a recessed grip for opening or closing the dishwasher.

From the DE 199 07 233 A1 a dishwasher is known in the appliance door, a control panel is provided, in which a handle shell is formed. The handle shell has a handle shell lower part, which is integrally formed on the control panel, and arranged on the rear side of the control panel handle shell cover, with which an area provided by the grip shell engagement area is enclosed.

The engagement area provided by the recessed grip is partially limited directly from the back of the control panel, whereby the appearance of the door and the feel of the door operation is impaired. In addition, the back of the control panel can not be used for the arrangement of control electronics for the display and controls of the control panel in the area of the handle shell.

In the US 5,174,618 At the upper end of the appliance door of a dishwasher, a control panel is provided with an engagement opening. In this an opening handle or pawl is provided, which is arranged on the upper edge of the outer door of the appliance door and can be moved to open the door up. The upwardly movable pawl has a movement gap to the front of the control panel.

The dishwasher of the US 2003/0168080 A1 according to the FIG. 2 a door, the upper part of which is designed as a handle which can be engaged by a user's hand (see FIG. 2 ), ie the handle form an integral part of the door. A contact-sensitive sensor is provided on the graspable surface of the handle.

The object of the invention is to provide a household appliance with a door, the handle shell is stable and designed visually and haptic low.

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

The invention relates to a dishwasher, as a household appliance with a door, which has a control panel with a handle shell, which is formed at least from a handle shell base and a handle shell cover.

According to claim 1, the handle shell cover has a control panel facing side wall, which forms a double wall structure with intermediate free mounting space together with the control panel, wherein in the mounting space of the double wall structure, an electronic module is arranged approximately for control or display elements of the control panel.

The double-wall structure gives the user a solid, high-quality impression when intervening in the handle shell. Advantageously, therefore, can reach behind only a simple plastic material thickness, as is the case in the prior art, be avoided.

According to the invention, an electronic module for the operating or display elements carried by the control panel is arranged in the free mounting space between the control panel and the handle shell lid side wall. In this way, a display window for a display can be provided immediately above the engagement opening of the handle shell in the front wall of the control panel, which projects beyond the engagement opening at least partially in a device door high direction.

The complete assembled appliance door has a, to a useful space of the domestic dishwasher facing, planar inner door element, which may be bolted to a load-bearing door frame. The control panel can be placed on the door frame at the upper edge of the appliance door and also screwed to the inner door element.

For a space-saving use of the back of the control panel, the mounting space in the double wall structure in a door side direction parallel to the handle shell lid side wall or the control panel designed open so that over almost the entire door width a strip-shaped control module is integrally feasible through the mounting space.

The provided in the front wall of the control panel engagement opening of the handle shell may be limited in door high direction of an upper handle bar and a lower shell-shaped raised wall portion of the control panel. The handle bar and the wall section form the handle shell base. The handle bar can protrude in the depth direction of the appliance door in the door interior and connect the control panel front wall with the side wall of the handle shell cover. The length of the handle web therefore determines the size of the mounting space of the double-wall structure.

When opening the door or when lifting the household dishwasher over the handle shell, for example for transport reasons, the control panel is subjected to torsional forces. A dimensionally stable rigid design of the control panel is therefore important. Against this background, the control panel geometry can be designed in approximately box-shaped or hood-like manner, with a user-side front wall with display and / or operating elements integrated therein, which merges into a diaphragm skirt which is angled in the direction of the depth direction.

Preferably, the handle shell cover can be supported on the upper side extending diaphragm shroud or the glare roof. For this purpose, the handle shell cover can be extended in the device vertical direction with at least one support element, via which the handle shell cover can be supported on the glare roof. The handle shell cover or its support member may be sized so that it is braced without play in the installed position between the glare roof and the handle shell base. With the cover holder according to the invention between the handle shell base and the glare can the control panel front wall back remain free of fasteners. On the other hand, such elements can be provided on the glazed roof and on the handle shell lower part. The mounting space of the double wall structure therefore also remains free of such fasteners.

Assembly technology is simple, when the handle shell cover can be brought in a pivoting movement in its construction position. For this purpose, at least one articulation point can be provided on the handle shell lower part, such as an open groove or a breakthrough, in which the handle shell cover hooked by means of hooks and can then be pivoted into the construction position.

To secure the handle shell cover located in its construction position, the control panel may have a securing element to prevent inadvertent release of the handle shell cover from its construction position. Preferably, the securing element can be provided on the screen roof of the control panel. The securing element may preferably be a locking rib which engages behind the support element in a dismantling direction after swiveling in the handle shell cover.

In the event that the household dishwasher is raised above the handle shell, the support element of the handle shell cover acts as a power transmission bridge over which forces are introduced directly into the glare panel of the control panel without burdening fasteners of the handle shell cover.

A further simplification of assembly results when the handle shell cover has additional lateral guide walls, which can be guided during installation along corresponding outer walls of the handle shell base, whereby the handle shell cover is pre-centered during installation.

Hereinafter, an embodiment of the invention with reference to the accompanying figures is shown.

In the Fig. 1 is shown in a partial view of a door 1 of a dishwasher. The appliance door 1 can be actuated in a known manner via a horizontal, bottom-side pivot axis, not shown, and has at the upper edge a control panel 3 made of plastic material. The control panel 3 limited with a flange-developed blind casing 13 on the upper side of the door unit 1 and is connected via lateral, downwardly projecting connecting pin 5 in a manner not shown with a door assembly of the door 1. The control panel 3 has on its front wall 7 arranged in series controls 9 and a centrally located display 11 for displaying operating conditions or the like.

The user facing the front wall 7 of the control panel 3 goes to its opposite in the door side direction x side edges and at its upper side edge in the aperture 13. This forms on the upper edge of the door a glare roof.

Below the in the Fig. 1 shown display displays 11 is provided in an approximately rectangular shaped engagement opening 15 for an integrated in the control panel 3 grip 17. The grip 17 is according to the Fig. 3 executed in two parts with a shell bottom 19 and a handle shell cover 21. The handle shell lower part 19 delimited with a lower shell-shaped raised wall portion 23 and an opposite upper, horizontally extending grip web 25, the insertion opening 15 of the handle shell 17. The handle shell lower part 19 is integrally integrated with its handle bar 25 and the lower wall portion 23 in the injection molding of the control panel 3. The geometry of the control panel 3 and the handle shell lower part 19 is selected so that no undercuts are present in the Entformungsrichtung E of the injection molding tools.

Like from the Fig. 3 further shows, in the horizontal direction between the handle bar 25 and the upwardly drawn wall portion 23, a free cut formed, which is bounded by a peripheral abutment edge 27. On the contact edge 27 sits the handle shell cover 21. This is in the side sectional view of Fig. 3 shown in trapezoidal shape with a front side edge 29 and a rear side edge 31, which are respectively in contact with the handle bar 25 and the raised wall portion 23 of the handle shell lower part 19. The side flank 29 of the handle shell cover 21, together with the control panel front wall 7 in the area above the engagement opening 15, a double wall structure 16 with transversely extending handle bar 25. This connects the two walls, ie front wall 7 and side edge 29 with each other. Between the side edge 29 of the handle shell cover 21 and the front wall 7 of the control panel 3, a free mounting space 33 is provided, is guided by the according to the figures, only indicated by dashed lines electronics module 35 along the back of the control panel 3. The size of the mounting space 33 in the Bautiefenrichtung 4 is determined by the length of the handle bar 25.

The electronic module 35 is assigned to the operating and display elements 9, 11 of the control panel 3. According to the Fig. 2 the electronic module 35 is strip-shaped and guided by the mounting space 33 of the double-wall structure 16. The electronics module 35 thus extends almost over the entire width of the appliance door. 1

Like from the Fig. 2 and 3 further, the handle shell lid 21 is supported by lateral support members 37 on support ribs 39. The roughly bay-like running support elements 37 are dimensioned so that in the installed position of the handle shell cover 21 are braced without play between the support ribs 42 and the abutment edge 27 of the handle shell lower part 19. The support ribs 42 are integrally formed on the rear panel 13 according to the figures.

According to the Fig. 2 For example, each of the support elements 37 has two shaft walls 38, which are connected to each other at the front end via an elastically yielding latching wall 39.

The shaft walls 38 of the support members 37 are according to the Fig. 3 in the construction position positively on a contact shoulder of the support ribs 42. When swinging the handle shell cover 21 according to the Fig. 4 become the elastically yielding Latching walls 39 of the support members 37 guided past locking ribs 41. The locking walls 39 are elastically bent from its rest position. In construction position of the handle shell cover 21, the locking walls 39 jump back to their rest position, whereby the locking rib 41 engage behind the locking walls 39. In this way, the handle cover 21 is held securely in the shown construction position.

Based on Fig. 4 the assembly of the handle shell cover 21 on the control panel 3 is described below. Consequently, the handle shell cover 21 is pivoted in a pivoting movement I in its construction position, which in the Fig. 2 is shown. To execute the pivoting movement, the handle shell cover 21 has lateral suspension hooks 43. These are according to the Fig. 4 guided by the lateral openings 45 on the handle shell lower part 19, whereby a hinge point is formed, via which the handle shell cover 21 is pivotable into the construction position.

In the Fig. 5 is shown in a modification an alternative embodiment of the handle shell lower part 19. Accordingly, the handle shell base 19 has no lateral openings 45 into which the hooks 43 can be inserted from above. In contrast to the preceding figures, the articulation point is designed via a guide groove 47 which is open in the depth direction, as well as a T-shaped suspension lug 49 which can be inserted therein and which is integrally formed on the handle shell cover 21.

According to the Fig. 2 and 4 the laterally outer shaft walls 38 of the support elements 37 are extended downward so that they laterally overlap outer walls 40 of the handle shell lower part 19. The laterally downwardly extended shaft walls 38 thus serve as guide walls, with which the Einschwenkvorgang is performed in the device side direction. <B> LIST OF REFERENCES </ b> 1 door l Pivotal movement direction 3 control panel x Device side direction 5 connecting pins y Bautiefenrichtung 7 Front wall of the control panel 3 z vertical direction 9 controls 11 display display 13 Fascias roof 15 engagement opening 17 grip 19 Grip bottom 21 Grip cover 23 raised wall section 25 Connecting bridge 27 contact edge 29 front side flank 31 rear side flank 33 mounting space 35 electronic module 37 support elements 38 Retaining walls 39 engaging wall 41 locking ribs 42 support ribs 43 hooks 45 breakthrough 47 guide 49 T-shaped hanging loop 40 Side walls of the grip 17 e unmolding
