Abstract

A kitchen appliance operable by electric motor includes a housing, which has an outer surface, and a data transmission interface designed to interact with a data memory element. The data transmission interface is formed in an outer surface of the housing by metal contact elements, which are arranged adjacent to each other and which each have a contact surface and form part of the outer surface. Further, a data memory element for transmitting data to a kitchen appliance operable by electric motor includes a plurality of contact elements that are separate from each other and optionally a contact surface. Further, a combination of a kitchen appliance operable by electric motor and a data memory element, which can be detachably connected to the kitchen appliance, can transmit data of the data memory element to the kitchen appliance while the data memory element is connected to the kitchen appliance. Further, a combination of a kitchen appliance operable by electric motor and a data memory element, which can be handled as an individual part, can bring the data memory element into contact with the kitchen appliance for data exchange.

First claim

The invention claimed is:

1. An electrical appliance comprising:
an electric motor,
a housing, which has an outer surface,
a data memory element, and
a data transmission interface designed to interact with the data memory element,
wherein the data transmission interface is formed in the outer surface of the housing by metal contact elements, which are arranged adjacent to each other and which each have a contact surface and form part of the outer surface,
wherein, in the area of the data transmission interface, the outer surface of the housing is designed as a partial outer surface, which is offset towards the interior of the appliance, and
wherein the metal contact elements rise beyond the plane of the partial outer surface by a measure, which corresponds to no more than the largest extension thereof, or less, or are shifted back by such a measure relative to the plane.

2. The appliance according to claim 1 , wherein the data memory element has a non-volatile memory.

3. The appliance according to claim 1 , wherein the data memory element has a cryptographic memory.

4. The appliance according to claim 1 , wherein the data transmission interface comprises a standard universal serial bus interface in addition to the metal contact elements.

5. The appliance according to claim 1 , wherein provision is made for three or more common contact elements.

6. The appliance according to claim 1 , wherein the metal contact elements are arranged along a straight line.

7. The appliance according to claim 1 , wherein the appliance is a kitchen appliance further comprising a mixing vessel and an agitator within the mixing vessel.

8. The appliance according to claim 7 , wherein the partial outer surface is closed in a depth direction towards an interior of the kitchen appliance so as not to have any apertures, openings, or depressions towards the interior of the kitchen appliance, and wherein the contact surfaces are embodied in a surrounding bearing surface having essentially the same height as the contact surfaces.

9. The appliance according to claim 8 ,
wherein the partial outer surface has an area center and
wherein the metal contact elements are arranged outside of the area center.

10. The appliance according to claim 8 , wherein provision is made for at least one magnet located in the partial outer surface.

11. The appliance according to claim 10 , wherein a magnet is provided laterally offset to a metal contact element.

12. The appliance according to claim 10 , wherein a magnet is invisible from outside.

13. The appliance according to claim 10 , wherein provision is made for two magnets.

14. The appliance according to claim 13 , wherein a distance between the magnets is larger than a distance between two outermost metal contact elements, which are arranged adjacent to each other.

15. The appliance according to claim 10 , wherein a magnet is arranged below the partial outer surface.

16. The appliance according to claim 8 , wherein the metal contact elements extend in the plane of the partial outer surface.

17. The appliance according to claim 8 ,
wherein the partial outer surface has a layout contour, which has curves,
wherein the layout contour is circular or the layout contour is oval.

18. The appliance according to claim 8 ,
wherein the partial outer surface has a layout contour, which has curves,
wherein a largest extension of the layout contour is between 1 and 10 cm.

19. The appliance according to claim 8 , wherein provision is made in the partial outer surface for at least one magnetizable area.

20. The appliance according to claim 8 , wherein the metal contact elements are combined in an elevated rib on a bottom of the partial outer surface.
