Description

The invention relates to a dishwasher, in particular a domestic dishwasher, with a dishwasher located in a body of the dishwasher for cleaning crockery, glasses, cutlery or the like to be cleaned items, the washing container on its front from a upright in a closed position and movable to its opening Door is closed and wherein the door is assigned in its closed position in the upper area a control panel, according to the preamble of claim 1.

It is known that such dishwashers, which include a control panel in the upper part of the door and thus either alone or under a worktop are supported and then referred to as so-called. Semi-integrated equipment to be provided with an outer panel in the form of a stainless steel hood to order to allow a high quality appearance and easy cleaning.

However, the design possibilities of such a closed hood are limited. Especially with larger cutouts - such as display window - such a hood is easily unstable, which makes installation difficult and reduces the durability.

The invention is based on the problem of creating new design possibilities for a metallic panel of a control panel.

The invention solves this problem by a dishwasher with the features of claim 1 or claim 4. Further advantages and features and further developments of the invention are specified in claims 2 to 3 and 5 to 17, the features of each be realized individually or in combination with each other can.

With the invention in training according to claim 1, characterized in that a display window extends at least almost over the entire width of the control panel and below the display window over the width of the control panel a metallic strip as Panel is arranged, created a new, emphasizing the width and horizontal orientation design, which no longer requires a cross-cap due to the separate metallic strip, which may be glued and pressed, for example.

For a still closed in the upper part of the door optics can be advantageously provided in addition to the metallic strip of the front on the transverse sides facing surfaces and on a closed position of the door upwardly facing surface at least one further metallic cladding, for example, a frame approximately C-shaped frame which overlaps the upwardly facing surface and the two sides facing the transverse sides. If the user-operable buttons and / or sensor surfaces are provided alone on the upper side, the front side can be designed to be particularly uniform throughout. This also contributes, if the display window initially appears uniform and backlit only from behind, so that only when information lights a deviation from the uniform, continuous surface appears.

If, as in claim 4, the door on its front side in the closed position a metallic cladding and pointing to the transverse sides surfaces of the control panel further metallic cladding, the metallic cladding of the front and the lateral sides facing surfaces via a bridging contact body electrically are conductively connected to each other, a continuous hood is no longer required for the functionality. Instead of a continuous metallic hood here individual metallic elements are provided so that the design possibilities are considerably expanded. Nevertheless, it is ensured by the at least one contact body that the electronics are protected and can build up any electrostatic potentials and unload uncontrollably.

In particular, each transverse side of the control panel is associated with a contact body, which ensures that reliable electrical contacts are formed.

In particular, the or each contact body in each case an electrically conductive connection between the front, the transversely outwardly facing side and the Rear side of the control panel ago, in order to electrically connect all the panel body covering parts together.

If at the back of the door a the control panel with overlapping large-area metallic cladding, the so-called. Interior door is arranged, there is no further metallic cladding for the visor body required, but this is directly integral with overlapped with the inner door, which thereby with on the Contact body rest and thus can be contacted via this.

In particular, the bridging contact body forms a spring clip, which can be optimized in its shape and residual stress in each case for the geometric conditions.

If the contact body in plan view is substantially C-shaped and rests with a first leg on the front, with a middle leg on the side facing the transverse side and with a rear leg on the back of a base of the control panel, the front and back and also the transverse outer side be electrically connected to each other at the same time, the effort for this is minimal.

Very favorable while the contact body has at the same time mechanically holding contact with the main body of the control panel and electrically conductive contact to the outside on this attached metallic panels.

For example, the contact body may be formed of spring steel and achieve its secure hold in that it is mounted under bias. Further connection means is not required.

To ensure that the contact body on the one hand is held securely and on the other hand contacted all outside of this adjacent metallic trim parts, the contact body low on the middle leg on a bias-locking kink. Additionally or alternatively, the contact body in each case from the contact surface on Base body of the control panel have outwardly extending formations that ensure the contact to the outside.

The mechanically secure hold is further supported if the main body of the control panel has recessed receiving areas for the contact body. Then this does not obstruct the outer surface of the body.

In this case, the contact body can simply be clipped into the receiving areas for assembly purposes. In particular, he is alone secured over residual stress in its position.

Further advantages and features will become apparent from the drawing illustrated and described below embodiments of the subject invention.

Elements with the same function and mode of operation are each provided with the same reference numerals in the figures.

In the FIG. 1 Dishwasher 1 shown schematically is a domestic dishwasher and has as part of a body '5 a washing container 2 for receiving ware to be processed dishes, pots, cutlery, glasses, cooking utensils u. on. The washing container 2 may have an at least substantially rectangular plan with a front side V facing a user in the operating position. The front V can form part of a kitchen front of kitchen furniture standing side by side or even be without reference to other furniture in a stand-alone device.

The washing container 2 can be closed by a door 3, in particular on this front side V. This door 3 is in FIG. 1 shown in partially open and then inclined to the vertical position. In its closed position, however, it is upright and is to its opening, for example, about a lower horizontal axis forward and downward in the direction of arrow 4 swung open, so that it is at least almost horizontal in the fully open position. At its in the closed position vertical, the user-facing outside the door 3 may be provided with a decorative plate 6, so as to experience a visual and / or haptic appreciation and / or adaptation to surrounding kitchen furniture.

The dishwasher 1 is formed here as a stand-alone or as a so-called. Partially integrated device.

The movable door 3 is assigned a control panel 8 in its upper area, which comprises a front access opening 7 for manually opening and / or closing the door 3. As in FIG. 2 becomes clear, this engagement opening 7 is in particular part of a Blendengrundkörpers 9, which may be formed, for example, as a one-piece KunststoffSpritzgußteil and to its completion, inter alia, still be provided with display and control electronics and outside panels.

In particular, the front side V of the door 3 is assigned a display window for wash program data, time, date, temperature, energy requirement, remaining shelf life and the like.

This display window 10 extends in the transverse direction Q at least almost over the entire width of the control panel 8. Here it extends completely over the width of the front side V of the door 3, such as in FIG FIG. 1 is indicated. The display window 10 may be uniformly tinted such that displays only become visible when they light up behind it. Otherwise, only a uniform dark tinted surface is visible.

Below the display window 10 is also on the width of the control panel 8, a metallic strip 11, for example, with a brushed or polished front surface, arranged as a panel. This metallic strip 11, which forms a lining, is here referred to in FIG FIG. 2 shown Blendengrundkörper 9 - for example, a plastic injection molded part - glued and in particular pressed with this, so that a stable and non-detachable unit is formed.

In addition to the metallic strip 11 of the front side V, further metallic claddings 15, 16 are provided on surfaces 12 facing the transverse sides and on a surface 13 pointing upward in the closed position of the door Shutter body 9 according to FIG. 2 not mounted yet. Thus, a substantially C-shaped metallic frame as the outer panel 15, 16, the surfaces 12 and 13 engage over the same time and release a window 14 in its middle leg 15 for the penetration of control buttons, sensor surfaces and the like. The front V can then remain completely free of such controls.

In order to ensure even with such a waiver of a continuous metallic hood protection against charging sensitive electronics and to ground the door 3 total, which are located on their front side in the closed position metallic cladding 11 and the pointing to the transverse sides surfaces 12 metallic cladding 16 via at least one bridging contact body 17 electrically connected to each other.

Here, each transverse side 12 of the control panel 8 is associated with such a contact body 17.

In this case, the contact body 17 produces an electrically conductive connection between the front side V, the side 12 pointing transversely outwards, and the rear side 18 of the control panel 8. In this case, the rear side 18 is overrun by a total of the door 3 inwardly facing, structured sheet metal, the so-called. Interior door 19, which is firmly connected, inter alia, via screw 20 with the diaphragm body 9. This inner door 19 is electrically conductively connected via the contact body 17 with the side panels 16 and the front panel 11, wherein the contact body 17 is held even in a continuous or multi-part recess 22 of the diaphragm body 9 under these metallic panels 11, 16, 19, that he himself contacts these, but is not visible from the outside. This recess (s) 22 forms or form a recessed region approximately in the thickness of the spring clip 17, that is about 1 to 4 millimeters. The contact body 17 is clipped or snapped into the receiving areas 22 of the non-conductive main body 9, which can be done both manually and in automated assembly. In particular, the spring clip 17 is axially symmetrical, so that incorrect assembly is excluded.

The bridging contact body 17 is here formed by a spring clip made of a spring steel and attached under pretension to the diaphragm base body 9 and held there solely by its residual stress. Gluing, compression or other additional holding measure for the contact body 17 is not required. This holds with its inherent stress-locking on the base body. 9

This the contact body 17 forming spring clip is in plan view ( Fig. 8 respectively. Fig. 9 ) is substantially C-shaped and is located with a first leg on the front side V, with a middle leg on the side facing the transverse side 12 and with a rear leg on the back 18 of the main body 9 of the control panel 8.

In this case, the contact body 17 is formed so that it not only mechanical contact with the base body 9 of the control panel 8, but also on the outside of this attached metallic panels 11, 16 and 19, has. These overlap the contact body 17 in the mounted position on the outside, so that it is then no longer visible from the outside. The said parts are electrically conductive on the contact body 17.

In order to ensure this contacting at all times, the contact body 17 on the middle leg may have a prestressing securing kink point 21, as in the broken plan view of the base body 9 after FIG. 9 is shown. Additionally or alternatively, as in FIG. 8 is drawn, the contact body 17 each have from the contact surface on the base body 9 of the control panel 8 outwardly extending formations 23 and above the electrically conductive contact to the outer panels 11, 16, 19 produce. A combination of formations 23 and a kink 21 is possible.

The - formed in particular of stainless steel - panels 11 and 15, 16 are mounted on the surfaces of the body 9 after assembly of the spring clip 17 and thereby receive forcibly and without further action contact with the spring clip 17. It is in addition to gluing and pressing and a mechanical crimping For example, the contiguous stainless steel frame 15, 16, on the plastic body 9 possible.

In any case, a bias voltage is generated in the spring clip 17, so that all components are contacted. By the equipotential spring 17 is an electrically conductive connection of the stainless steel front pad 11, the side and top frame 15, 16 and the rear inner door 18 is formed.

With static charging of the front 11 or lateral components 15, 16, a potential equalization for the grounded inner door 19 takes place with the spring 17.

Overall, this type of equipotential bonding is very inexpensive, since such spring steel strap 17 are very inexpensive and easy to assemble. Nevertheless, a permanently reliable protection of the control electronics and the display module against electrostatic charges is achieved. Without the contact body would be in such a multi-part panel, for example, the front support 11 made of stainless steel and the side and top frame 15, 16 - also made of stainless steel - not electrically connected to each other. <B> LIST OF REFERENCES: </ b> 1 Dishwasher, 16 lateral metallic cladding, 2 Processing vessel 17 Contact body 3 Door, 18 Rear of the control panel, 4 Pivot direction, 19 Inner door, 5 body, 20 screw connections, 6 Decorative plate, 21 Kink, 7 Engaging opening, 22 recess 8th Control panel, 23 formations 9 Aperture body, 10 Display window V Front, 11 front panel, Q transversely 12 lateral area, 13 upper surface, 14 Penetration window 15 upper metallic cladding,
