Description

The invention relates to a household appliance with a pivoting appliance door, via which an appliance opening connected to a treatment chamber of the household appliance can be closed, the appliance door being set up to accommodate a door part of a furniture front on a front side, a panel support which is designed separately from the appliance door and is set up for this purpose is to receive a cover part of the furniture front in a receiving area, and an electronic display and/or operating unit.

Furthermore, the invention relates to a built-in system with a household appliance and a furniture front, which includes a door part and a panel part.

From the DE 10 2004 015751 A1 discloses a household appliance with a front side that runs essentially perpendicularly to the installation surface when the household appliance is in the normal operating position, on the outer surface of which a desk-like operating and display device is arranged, control electronics being located inside the housing of the operating and display device, which the operating and display elements of the operating and display device and is in signal transmission connection with power electronics arranged in the rest of the household appliance. An embodiment disclosed in that document provides that the household appliance has a body and a door, and that when the door is closed the operating and display device covers an intake or exhaust opening arranged on the body in such a way that the operating and display device the intake opening diverts air flowing in or out of the exhaust opening in a predetermined direction.

Integrated household appliances, which are set up for use with a furniture front, usually have a large receiving area for a single furniture front part. The display and/or operating elements of the household appliance are located on the appliance door, as a result of which the appliance door is designed to be comparatively high. When open, the household appliance has limited accessibility due to the high appliance door. In corresponding devices, the device-internal airflow is also changed compared to comparable devices without optimization for use behind a furniture front, since no air gap can be implemented across the full width of the household appliance on the front of the household appliance, through which a vapor flow to be discharged from the household appliance can escape from the household appliance can be directed out.

In built-in systems whose furniture front includes a door part and a panel part that is separate from the door part, the furniture maker would previously have had to make a complex and extensive adjustment of the panel part to integrate the electronic display and/or Operating unit required to create a recess to accommodate the latter. Ultimately, this would lead to a significantly increased assembly effort and thus also to significantly increased assembly costs and would therefore be disadvantageous. The post-processing of furniture fronts also harbors the risk of damage to the front, for example in the case of high-gloss lacquered fronts. With certain front materials such as concrete or glass, subsequent processing is difficult or even impossible.

The object on which the invention is based is therefore to simplify the installation of an electronic display and/or operating unit in a household appliance whose furniture front is divided into a door part and a panel part.

The object is achieved by a household appliance according to claim 1, wherein, among other things, the display and/or operating unit of the household appliance according to the invention is set up to be attached to the panel support and/or the panel part of the furniture front by means of one or more attachment members at a distance from the receiving area become.

Due to the fact that the display and/or operating unit is attached to the panel support and/or the panel part of the furniture front at a distance from the receiving area, the display and/or operating unit is located outside of the receiving area. By attaching the display and/or operating unit, the display and/or operating unit is thus brought forward so that free installation space is created for the cover part of the furniture front. The panel part of the furniture front can thus be installed in the receiving area of the panel support without the need for time-consuming and costly processing of the panel part of the furniture front in order to create a recess for the display and/or operating unit. The appliance door and the panel support are designed as separate components, so that an acceptable appliance depth is maintained even when the appliance door is open. The treatment room thus remains easily accessible for the operator of the household appliance. This applies in particular to household appliances in the 60cm class.

The door part and the panel part of the furniture front are separate furniture front parts. The appliance door has a mounting option for the door part of the furniture front. The panel support has a mounting option for the panel part of the furniture front. The door part can essentially cover the entire surface of the appliance door, but alternatively only part of the appliance door, for example only a lower part of it in the case of a fully automatic coffee machine.

Because the display and/or operating unit is arranged at a distance from the receiving area and outside of the receiving area, the display and/or operating unit is visible and accessible to the operator of the household appliance at all times. The operability of the household appliance according to the invention thus corresponds to that of a non-integrated household appliance. According to the invention, the display and/or operating unit can rest on the panel part of the furniture front or be attached at a distance from it.

The display and/or operating unit can be arranged in such a way that it essentially does not protrude into the receiving area or the furniture front, but small parts of it can protrude into the receiving area or the furniture front. Positioning pins or the like are mentioned as an example, which protrude into holes or blind holes, which may have to be created by the furniture maker when installing the device, in order to fix the display and/or operating unit in position. Lines for the power supply of the display and/or operating unit and/or for signal transmission can also protrude into the areas mentioned or penetrate the panel part of the furniture front.

The display and/or operating unit can be screwed to the panel support and/or the panel part. The display and/or operating unit preferably has a display. The display can be designed as a touchscreen. One or more separate operating elements, such as cups or switches, can be arranged above, below and/or to the side of the display. The separate operating elements are used, for example, to actuate a sensor or to switch the household appliance on and/or off and/or to switch individual appliance functions on and/or off.

In the household appliance according to the invention, a horizontally or vertically extending gap is arranged between the appliance door and the panel support, which gap fluidly connects a device-internal line system to the surroundings of the household appliance. The gap can, for example, extend over the entire width or height of the household appliance. Vapors, steam and/or hot air, for example, can be discharged from the household appliance, in particular from the treatment room of the household appliance, via the gap. Below or to the side of the gap is preferably a handle attached to the appliance door, via which the appliance door can be swung open. The handle is preferably designed in such a way that it can be gripped from below, so that contact with a fluid flowing out of the gap, for example with a vapor stream, is avoided even when the handle is gripped by an operator of the household appliance.

In a further embodiment of the household appliance according to the invention, the gap is completely or partially covered by the panel support and/or the furniture front and/or the display and/or operating unit when the appliance is at rest. In the operating state, the panel support can be moved in order to release a sufficiently large opening for the vapor to be discharged.

In the household appliance according to the invention, one or more flow guide elements are arranged on the panel support and/or on the display and/or operating unit, which are set up to deflect a fluid flow emerging from the gap. The fluid flow emerging from the gap is preferably a vapor flow. The fluid flow is diverted in order to direct the fluid flow away from the sensitive display and/or operating unit and/or the sensitive furniture front.

In a further preferred embodiment of the household appliance according to the invention, a liquid container is arranged on the appliance side behind the panel support and the panel support is set up for this, together with the display and/or operating unit and the panel part of the furniture front, from a rest and/or operating position in which the panel support and / or cover the panel part of the furniture front, the liquid container, to be moved into a release position in which the liquid container is accessible from the outside. The household appliance preferably has a steam cooking function. The liquid container is preferably a water container in which water is stored, which the household appliance uses to generate steam. Instead of the liquid container, there can also be electronics and/or an air duct on the device side behind the panel support, which can be made accessible to an operator of the household appliance by moving the panel support from the rest and/or operating position into the release position. Alternatively, the panel support can also be mounted immovably, for example if the household appliance is an oven without a steam cooking function.

Further alternatively, the household appliance can be a fully automatic coffee machine. A bean container, which is accessible in the release position, can also be arranged in this in addition to or instead of the liquid container. In principle, it can be any container or any part of any household appliance that is to be made accessible in the release position, for example for the purpose of refilling an operating resource and/or for cleaning/maintenance.

In a further preferred embodiment of the household appliance according to the invention, the display and/or operating unit is set up to be inclined after it has been attached to the panel support and/or the panel part of the furniture front. In this case, the tilting of the display and/or operating unit preferably takes place about a tilting axis running in the horizontal direction, in particular when the display and/or operating unit is arranged

Operating unit above the appliance door. Alternatively or additionally, the display and/or operating unit can be tilted about a tilting axis running in the vertical direction, in particular when the display and/or operating unit is arranged on the side of the appliance door. The display and/or operating unit can thus be suitably aligned depending on the installation location of the household appliance and possibly depending on the design of the appliance door/the arrangement of the display and/or operating unit in relation thereto. If the household appliance is installed high, the display and/or operating unit can thus be tilted downwards. If the household appliance is installed deep, the display and/or operating unit can thus be tilted upwards. The tiltability of the display and/or operating unit is preferably implemented via a seesaw-like construction or via one or more swivel joints.

A household appliance according to the invention is also preferred in which the display and/or operating unit is designed to be at least partially recessed or retractable in the panel part of the furniture front after attachment to the panel support and/or the panel part of the furniture front. In the case of the latter, the display and/or operating unit can be tiltable and/or linearly movable for this purpose. One or more fastening elements, by means of which the display and/or operating unit can be fastened to the panel support and/or the panel part of the furniture front, are preferably designed to be retractable and extendable.

In a further preferred embodiment of the household appliance according to the invention, the display and/or operating unit is set up to be supplied with energy wirelessly and/or to transmit and/or receive display and/or operating signals wirelessly. The display and/or operating unit can have a receiver circuit which has one or more receiver antennas and/or one or more receiver coils. The one or more receiver antennas and/or the one or more receiver coils of the display and/or operating unit can be coupled to one or more transmitter antennas and/or one or more transmitter coils of a transmitter unit for power supply. The transmission unit can be arranged on the panel support. The display and/or control signals can be transmitted via near-field communication and/or via radio. This makes it possible for the display and/or operating unit to be attached to the panel part of the furniture front without continuous attachment members and power/data lines. This makes it possible to stick on the display and/or operating unit without interfering with the cover part; alternatively, screws can also be used, but they do not penetrate the entire depth of the cover part.

A household appliance according to the invention is also advantageous in which a fastening element is designed as a holding element which is arranged completely outside the receiving area and is set up to fasten the display and/or operating unit to the panel support. There are therefore no fastening members required, which extend through the receiving area and thus through the panel part of the furniture front. Thus, no holes or other recesses are required on the panel part of the furniture front. The assembly of the display and/or operating unit is thus considerably simplified and accelerated.

One or more electrical lines can be routed on and/or in the holding element. Electrical lines can also be integrated or embedded in the holding element. The holding element can also function as a flow guide element, which is set up to deflect a fluid flow emerging from the gap between the appliance door and the panel support. The holding element can extend, for example, in the transverse direction over the entire width of the display and/or operating unit or over the entire width of the household appliance. The holding member may have a C- or L-shaped cross section.

The object on which the invention is based is also achieved by a built-in system of the type mentioned at the outset, the domestic appliance of the built-in system according to the invention being designed according to one of the embodiments described above. The door part of the furniture front is attached to the front of the appliance door. The panel part of the furniture front is fastened in the receiving area of the panel support.

The 1 shows a built-in system 100 with a household appliance 10 and a furniture front 102. The household appliance 10 is an oven with a steam cooking function. The furniture front 102 is designed in two parts and has a door part 104 and a panel part 106 . Each of the door part 104 and the screen part 106 is a decorative plate made of wood, for example. All other materials that can be used for furniture fronts, such as ceramic/mineral Alternatively, materials such as stone, plastics, metals/metal alloys, glass, and laminates of various materials may also be used.

The household appliance 10 has a pivotable appliance door 12, via which an appliance opening connected to a treatment room or, in this example, a preparation room 14 of the household appliance 10 can be closed. In this case, the preparation space 14 is a cooking space of the household appliance 10. The door part 104 of the furniture front 102 is fastened to the front of the appliance door 12. The appliance door 12 can be rotated or pivoted about a horizontal axis or alternatively (not shown) a vertical axis.

The pivotable appliance door can have a horizontal pivot axis, as is common in many cooking appliances, but alternatively also a vertical pivot axis, as is often the case in built-in microwave ovens, for example. The operating and display unit or the panel part are then arranged either above or to the side of the appliance door or of its door part.

A panel support 18 is located above the appliance door 12 , the panel part 106 of the furniture front 102 being fastened in a receiving area of the panel support 18 .

The household appliance 10 also includes a display and control unit 20 which is attached to the bezel support 18 by means of the attachment members 22a, 22b of the household appliance 10 at a distance from the receiving area of the bezel support 18 . In the embodiment shown here, the display and operating unit 20 is also positioned at a distance from the panel part 106 of the furniture front 102 that is arranged within the receiving area of the panel support 18 .

The 3 shows a household appliance 10 whose display and control unit 20 can be tilted about a tilting axis running in the horizontal direction after it has been attached to the panel support 18 . The display and operating unit 20 can thus be tilted downwards in the case of high installation and tilted upwards in the case of deep installation. The tiltability of the display and control unit 20 can be implemented, for example, via a seesaw-like construction or via one or more rotary joints.

The 4 shows a household appliance 10 in which a fastening member 22 is designed as a holding element which is arranged completely outside the receiving area of the panel support 18 . The display and operating unit 20 is fastened to the panel support 18 by means of the fastening element 22 embodied as a holding element. Due to the fact that the holding element is arranged completely outside the receiving area of the panel support 18, no fastening members are required which extend through the panel part 106 of the furniture front 102. Consequently, no holes or other recesses are required on the panel part 106 of the furniture front 102 . The fastening element 22 embodied as a holding element can extend, for example, in the transverse direction over the entire width of the display and control unit 20 or over the entire width of the household appliance 10 .

The figure 5 shows a household appliance 10 in which a flow guide element 32 is arranged on the screen support 18 . The flow guide element 32 is set up to deflect a fluid flow 26 emerging from the gap 24 . The fluid flow emerging from the gap 24 is, for example, a vapor flow. The fluid flow 26 is redirected to direct the fluid flow 26 away from the sensitive display and control unit 20 .

Furthermore, the display and control unit 20 is attached directly to the panel part 106 of the furniture front 102 . For example, the display and control unit 20 is screwed to the panel part 106 of the furniture front 102 via the fastening element 22 .

The display and control unit 20 can be set up to be supplied with energy wirelessly. For this purpose, the display and control unit 20 can have a receiver circuit, which is supplied with energy from a remote transmitter unit. The transmission unit can be arranged on the panel support 18, for example.

Furthermore, the display and control unit 20 can be set up to send and/or receive display and/or control signals wirelessly. The display and/or control signals are transmitted, for example, via near-field communication and/or via radio.

The household appliance can also be a dishwasher, which can be designed analogously to the above-mentioned examples of other household appliances, but in particular not necessarily in the case of overhead installation.
