FIG. 1 shows a partial section through a domestic appliance operating device, which has a first and at least one second power line element 10, 12. The second power line element 12 has a sliding contact 42 which is connected to the first power line element 10, which is formed by a conductor track of a board 38 of the home appliance operating device, in a in FIG. 1 shown operating position is present. As a result, the two power line elements 10, 12 are conductively connected to each other. The power line elements 10, 12 are parts of a power supply device which supplies power to a load unit 30 of the home appliance operating device during operation of the home appliance operating device. Furthermore, the two power line elements 10, 12 form a sliding contact unit 18. For this purpose, the household appliance operating device has a bearing unit 14, which rotatably supports the second power line element 12 by three hundred sixty degrees about an axis of rotation 40 relative to the first power line element 10. When the second power line element 12 is rotated about the axis of rotation 40 by three hundred and sixty degrees relative to the first power line element 10, the second power line element 12 will grind about the first power line element 10 over an angle of rotation of about three hundred and twenty degrees, with the two power line elements 10 and 12 constantly moving are conductively connected to each other.

The second power line element 12 has a Hauptersteckungsrichtung, which is parallel to the axis of rotation 40. One end of the second power line element 12 in the direction of its main direction of insertion is formed by the sliding contact 42. A sliding contact 42 with respect to the Hauptersteckungsrichtung opposite end of the second power line element 12 has a coupling means 16 which is formed as a connector means. The domestic appliance operating device further has a power line unit 20, which is attached to the coupling means 16 in a positive and non-positive manner. For this purpose, the power line unit 20 comprises a plug 44, which is plugged into the coupling means 16 and is destructive and tool-free from the coupling means 16 formed by the connector means removable.

The plug 44 is formed by a plug-shaped blade 70 and part of a flexible printed circuit board 68 of the power line unit 20 and has two pins 72 which are received in a receiving region 74 of the coupling means 16. The flexible printed circuit board 68 is bent around an end region 76 of the lamella 70 by a hundred and eighty degrees, so that the printed circuit board 68 is in an operating position (FIG. FIG. 1 ) bears against an upper side 78 and an underside 80 of the lamella 70. For fixing the circuit board 68 in this Position relative to the blade 70, the circuit board 68 is attached to the blade. The printed circuit board 68 has a foil and two wires (not shown) welded into this foil. Recesses 82 bordered by the foil release contact points on the wires which form contact points of the plug 44 and establish an electrically conductive connection to the coupling means 16.

The bearing unit 14 is designed as a plain bearing and has a bearing body 22, which bounds a receiving area 24 and thereby forms. For this purpose, a boundary surface 46, which delimits the receiving area 24, has a shape of a cylinder jacket of a cylinder with a rectangular base area. A majority of the second power line element 12 is arranged in the receiving area 24. Seventy percent of an extension length of the second power line member 12 along the main splitting direction of the second power line member 12 extend within the accommodating portion 24.

The bearing body 22 is formed of glass fiber reinforced polyamide 6.6. Furthermore, the bearing body 22 forms an inner ring 58 of the sliding bearing. An outer ring 60 of the sliding bearing, in which the inner ring 58 engages, is attached to the circuit board 38. The bearing body 22 further forms a receiving region 62, in which in a fully assembled state, a function selector engages (not shown).

The household appliance operating device has at least one functional unit 28 which is rotatably mounted by the bearing unit 14 ( FIGS. 1 and 2 ). The consumer unit 30 is part of the functional unit 28 and has a lighting means. In principle, the consumer unit 30 may also be formed by at least one electrical load, which differs from a lighting means. Furthermore, the functional unit 28 has an operating means 32, within which the consumer unit 30 is arranged. The operating means 32 is rotatable about the axis of rotation 40 and slidably mounted along the axis of rotation 40.

With the aid of a connecting means 34 of the household appliance operating device, the functional unit 28 is mounted on the storage unit 14 in a non-destructive and tool-free manner. The connecting means 34 is a plug-in means which is inserted into a receiving area 48 of the functional unit 28. The plug-in means is nose-shaped. Further, a leaf spring (not dargstellt) is arranged on the connecting means 34, which also is arranged in the receiving region 48 and which exerts a pressure on the functional unit 28, whereby the functional unit 28 is frictionally secured to the bearing body 22. If a sufficiently large train is exerted on the functional unit 28 along the axis of rotation 40 away from the power line elements 10, 12, then the functional unit 28 is non-destructive and can be detached from the bearing body 22 without tools and can thus be dismounted.

Furthermore, the domestic appliance operating device has a third and fourth power line element 50, 52, which are designed and arranged analogously to the first and the second power line elements 10, 12 ( FIG. 3 ). By means of the third and fourth current-conducting elements 50, 52, a closed circuit for a power supply of the consumer unit 30 is produced during operation of the consumer unit 30.

FIG. 4 shows a functional unit 28 with the home appliance control device, with only the control means 32 is visible.

In FIG. 5 an alternative embodiment of a portion of a home appliance control device is shown. Substantially identical components, features and functions are basically numbered by the same reference numerals. To distinguish the embodiments, however, the reference numerals of the embodiment in the FIG. 5 the letter "a" added. The following description is essentially limited to the differences from the embodiment in the FIGS. 1 to 4 , wherein with respect to the same components, features and functions on the description of the embodiment in the FIGS. 1 to 4 can be referenced.

This in FIG. 5 illustrated embodiment has a board 38a and an edge card connector 36a. A trace of the board 38a forms the first power line element 10a. At an edge region 56a of the board 38a has these contacts 54a. In a fully assembled state, the edge card plug 36a is stuck on the edge portion 56a. One of the contacts 54a provided a conductive connection between the edge card plug 36a and the first power line element 10a.

FIG. 6 shows a front view of the board 38a in an unmounted state. The power line element 10a has a part region formed as a sliding track 64a, which in the front view has a shape of a circular ring segment, which is in relation to the axis of rotation 40 extends over an angle 66a of about three hundred and twenty degrees. When the power line element 12 is rotated by three hundred and sixty degrees in a fully assembled state, conductive contact between the power line element 10a and the power line element 12 is achieved only by contact between the sliding track 64a and the power line element 12, thereby rotating the power line element 12 and the Power line element 10a are conductively connected only about about three hundred and twenty degrees with each other.
