Abstract

A mounting device (1) for receiving at least one preparation vessel (2) for food with a heating device having at least one receiving portion (4) for the preparation vessel (2) and at least three contact sockets (5a, 5b, 5c, 5d, 5e) for at least partially receiving corresponding contact pins (6a, 6b, 6c) on the preparation vessel (2). A mounting device (1) for receiving at least one preparation vessel (2) for food with a heating device, in which the user safety is improved, is realized in that at least one first of the contact sockets (5c) including at least one signaling means (8), that the signaling means (8) generates at least one insertion signal when one of the contact pins (6b) is inserted at least partially into the first contact socket (5c), that when the insertion signal is present, at least one other of the contact sockets (5a, 5b, 5d, 5e) can be supplied with a working voltage, and that without the insertion signal being present, none of the contact sockets (5a, 5b, 5c, 5d, 5e) can be supplied with a working voltage.

First claim

The invention claimed is:

1. A mounting device for receiving a preparation vessel for food with a heating device, comprising at least one receiving portion for the preparation vessel and at least three contact sockets for at least partially receiving corresponding contact pins on the preparation vessel, at least a first of the contact sockets comprises a signaling means for generating at least one insertion signal when one of the contact pins is inserted at least partially into the first contact socket, that when the insertion signal is present, at least one other of the contact sockets are supplied with a working voltage, and that without the insertion signal being present, none of the contact sockets can be supplied with the working voltage, wherein the first of the contact sockets is permanently electrically connected to a ground contact.

2. The mounting device according to claim 1 wherein, at least two of the contact sockets respectively comprise the signaling means, that the signaling means generates the insertion signal when each one of the contact pins is simultaneously inserted at least partially into each of the two contact sockets.

3. The mounting device according to claim 1 further comprising, the insertion signal is generated for a predetermined depth of penetration of at least one of the contact pins into at least one of the contact sockets at a depth of penetration of between 10% and 75% of a total depth of a contact socket.

4. The mounting device according to claim 1 wherein, the signaling means comprises at least one electrical switching element.

5. The mounting device according to claim 1 wherein, the signaling means comprises an actuating element movably retained in at least one of the contact sockets, and that the insertion signal can be generated at least indirectly by the actuating element.

6. The mounting device according to claim 5 further comprising, the actuating element is formed at least in part of a non-conducting material.

7. The mounting device according to claim 5 further comprising, the actuating element is guided in a switch housing, and that the switch housing is float mounted, and the switch housing is formed of at least two parts.

8. A mounting device according to claim 5 further comprising, a resetting means for acting on the actuating element.

9. The mounting device according to claim 7 further comprising, the switch housing and a contact retainer containing the contact sockets are aligned with the actuating element with respect to each other.

10. The mounting device according to claim 1 further comprising, at least five of the contact sockets are provided, a second of the contact sockets and a third of the contact sockets serve for connecting the heating device and a fourth of the contact sockets and a fifth of the contact sockets serve for connecting additional signals.

11. A kitchen appliance having the mounting device in accordance with claim 1 further comprising, at least one power supply and at least one motor for driving a rotating tool in the preparation vessel.

12. A mounting station having the mounting device in accordance with claim 1 further comprising, the heating device.

13. The mounting station according to claim 12 wherein, the mounting device further comprises, at least one mechanical interface for driving a rotating tool in the preparation vessel.

14. The mounting device according to claim 4 further comprising, the electrical switching element in the form of a microswitch or a magnet switch.

15. The mounting device according to claim 8 further comprising, the resetting means constantly exerts a force on the actuating element in the direction of a starting position, the resetting means comprises at least one of a spring or a magnet.

16. A mounting device for receiving at least one preparation vessel for food with a heating device, comprising at least one receiving portion for the preparation vessel and at least three contact sockets for at least partially receiving corresponding contact pins on the preparation vessel wherein, at least two of the contact sockets respectively comprise at least one signaling means, that the signaling means generates an insertion signal when each one of the contact pins is simultaneously inserted at least partially into each of the two contact sockets that when the insertion signal is present, at least one of the contact sockets can be supplied with a working voltage, and that without the insertion signal being present, none of the contact sockets can be supplied with a working voltage wherein one of the two contact sockets with signaling means is permanently electrically connected to a ground contact and one of the two contact sockets can be supplied with a working voltage.
