Out DE 30 37 277 A1 a microwave oven is known in which manually operated, electrically controllable operating devices are attached to the door. Disclosed are behind a front surface of a door located keypads, which can advantageously extend according to this device until the furnace chamber opening. Since the door occupies the entire front, a separate control panel can be omitted.

Out DE 38 29 913 A1 a microwave oven is known in which switching, setting and / or display means are installed in the cooking chamber door, behind a front wall.

DE 201 03 517 U1 describes a cooking appliance with functional cooking appliance door, in which contacts in the form of films are applied to the door and in particular displays on the at least partially transparent door can be projected, z. B. as in a so-called. Head-Up Display. The display and / or operating element can also be detachably attached to the cooking appliance door.

Out WO 97/26486 is a oven door with controls integrated into a handle known.

Out EP 1 120 606 A2 a cooking appliance door is known, distributed in its door control switch and display panels that complete flat with the front. This is relatively expensive to manufacture and wire.

It The object of the invention is an opportunity for easy and inexpensive manufacturing and easy installation, easy maintenance and to provide improved handling of controls.

The The object is a control module according to claim 1, a household appliance door according to claim 24 and a household appliance solved according to claim 25. advantageous Embodiments are in particular the dependent claims individually or in combination removable.

The Operating module has at least one operating element and is at least partially usable in a recess of a cooking appliance door.

One Operating module can be a bounded construction or functional group being part of a whole and being changed or exchanged can, without any interference or changes in the rest of the system become necessary (c.f. Bibliographisches Institut & F. A. Brockhaus AG, Mannheim; Spektrum Akademischer Verlag GmbH, Heidelberg, 2003); This may be convenient a separable from the household appliance door casing with at least the / the built therein control / controls be.

This Control module opposite distributed, individual controls have the advantage of being less and easier installation steps needed and easier exchangeable is. Across from behind the door front arranged elements gives the advantage of a possible lower installation height the door itself, because the case outward can stand out; In addition, a greater variety of switching elements (Toggle, toggle switch) possible, which can also be better operated. Across from on the door applied control units gives the advantage of a more reliable Attachment, z. B. by clamping on the door, a less prominent Design and easier connection to other device components, z. B. a power supply.

The Operating module can conveniently except Operating elements, d. h., switching elements (switches, toggles, buttons, Slider, etc.) and / or display elements (LED displays, alphanumeric Displays such as LCD full pixel fields, etc.), including an associated electrical system and / or electronics as well as suitable communication means for data transmission with other components, eg. As cables, cable connections, evaluation and / or control electronics, wireless transmission devices or the like.

To reduce heat absorption from the door or an interior of household appliances - z. B. a cooking chamber - has the respective operation module advantageously a (from the point of view of the household appliance) to the outside protruding part, which projects after installation in the door from the door surface to the outside, as well as an insertable into the recess part, which preferably protrudes from the insertable into the recess part behind the back. As a result, a thickness or installation depth of the door can also be reduced, and improved operability can be achieved.

there is it cheap if the usable part of the operating module in particular electrical and / or picks up electronic components while outwardly protruding Part includes in particular the controls. By such Arrangement it is possible a big Control panel, which can also be used laterally (up, down, left and / or right in plan view of the door) over the recess protruding can while the Recess even heat-insulated kept low and low can be.

One Provide one (in supervision of the door) laterally over the Recess or insertable into the recess part of the operating module outstanding part of the control module may be for reasons of heat dissipation and better usability in general.

Out establish the sealing of the door interior against the environment it is advantageous if the side (i.e., left, right, up and / or down) the recess protruding part on a front door panel, z. B. an outer or Windscreen, the household appliance door can be placed is, especially with a seal.

to further sealing a side edge of the door, especially with the side open recesses, it is advantageous if the operating module a Cover plate, which is used to cover at least one part, preferably the part opened by the recess, a side edge the household appliance door suitable is. It is also favorable, if in the area of the cover plate a seal to the side edge of Appliance door available is.

It can, for. B. for easier replacement and better attachment the operating module, be advantageous if the cover plate in the lateral direction over the adjacent to it (upper, lower, left and / or right) side edge protrudes.

The Above said applies especially to doors, one side of the household appliance cover without using a control panel. The optimization of Thermal insulation is particularly favorable for doors with - if necessary until on a narrow frame - fully glazed Surface.

to Optimizing the function of the operating module is favorable when the predominant Number of operating elements, in particular all operating elements, in a single control module are housed. Then it only needs a single recess in the door and thus only one insertion and Fastening operation. Also a repair becomes by exchange of the entire operating module cheaper.

It is advantageous for easy operation, if the operating module at least a display field, e.g. B. a pixelansteuerbares LCD display has and at least one rotary switch or toggle. It is special Cheap, if the at least one rotary switch below the display field is arranged.

to improved, particularly simple and intuitive user interface is Cheap, if buttons are attached to the side of the display panel, in particular, if the keys are left and / or right of the display panel are attached, in particular, when the keys are symmetrical left side and are mounted on the right side of the display panel.

It is also beneficial if the buttons are push buttons as they then can essentially form a surface plane with the display panel.

It is for example for improved ease of use and for improved cleaning ability advantageous when the buttons and the display panel by a common Cover, in particular a common disc, z. As a plastic disc "covered are.

Especially advantageous is an operating module, in which the display panel and / or the keys on the insertable into the recess part opposite Area of the outward protruding part are attached, since so a control and evaluation brought close to these controls, especially the display panel can be.

It is also advantageous if the at least one rotary switch on the laterally over the recess protruding, and in particular on a door panel attachable, part is arranged, because so the size and location of the rotary switch not limited by the recess and the recess can be kept small. This is especially true for the rotary switch an associated one Evaluation electronics is not needed or compared to the control electronics for the Display can be simple and small.

To avoid that a user gets stuck on one edge of the operating module, is güns Tilted outwardly projecting part at least partially beveled at an edge region, typically from the front surface to the rear, z. B. towards the front door panel. It is then favorable for maintaining a large packing volume of the operating module, in particular when the part projecting laterally beyond the cut-out is beveled, especially towards the front door panel. In this case, the part projecting laterally beyond the recess may be bevelled in one or more directions (eg on the left, on the right and / or upwards or downwards). It is particularly advantageous if the operating module bevelled on a side facing away from the edge of the appliance door side, z. B. chamfered is. The controls, z. B. rotary switch, can also be mounted in an area which is partially beveled and partially not bevelled.

It is advantageous for ease of use when the switches in pairs are arranged symmetrically about a central axis of the operating device. The central axis may be perpendicular to the edge of the appliance door and in particular a be vertical center axis.

For secure attachment, the operating module ( 2 . 33 ) in a rear region, in particular in the part to be inserted into the recess, at least one fastening element, in particular a thread for receiving a screw on.

The Task is also by a household appliance door, especially a cooking appliance door, especially one Oven door, with at least one recess for receiving in each case at least solved one of the above-described operating modules, in which a control module can be used. The door especially a door for cooking appliances, especially for ovens.

It it is advantageous if the operating module partially into the recess the door is inserted and partially protruding outward. Conveniently takes the usable part of the operating module in particular electrical and / or electronic components on while the outside projecting part in particular includes the controls.

The Recess can be introduced deep into the household appliance door as needed. To minimize the impact of a recess on a door, just needs the front door panel, z. B. the windscreen, are provided with the recess. Depending on Requirement, e.g. B. the internal structure of the door, the design of the control module or cooling requirements, can the recess also by other door elements, eg. B. more door windows, partitions or insulating areas, led become. It is also possible that the recess is passed through the entire door, so that the control module with its insertable into the recess Part through the door can be inserted.

The Recess, for example, a laterally open cutout at least the front door panel include; This is advantageous for easier installation. Alternatively, the recess of material at least the front panel on all sides be surrounded. The recess can also be open on two sides be. It is also possible that the recess is shaped differently in different layers of the door, z. B. as a laterally open recess in the front window and as enclosed recess in a disc behind it.

Of the outward projecting part can also be laterally in any direction (ie. h., left side, right side, up and / or down) over the go out into the recess to be inserted part.

It can also be cheap be when the door has a solid glass front, in which introduced the saving is. In particular, in a full glass door, it is advantageous if the door handle sideways in the door is integrated.

The Task is also solved by a household appliance, in particular a cooking appliance, the a door described above with at least one operating module described above suitable for use having. This is especially true for home appliances without separate control panel.
