Abstract

A PEF cooking appliance includes a PEF generator, and a carrier configured to receive a storage container for food. The carrier includes at least two PEF electrodes spaced apart to enable insertion of the storage container there between. At least one the PEF electrodes is connected to the PEF generator. The carrier is embodied as a drawer with a top cover pivotably attached thereto The drawer includes a base, with one of the two PEF electrodes being integrated into the base of the drawer and another one of the two PEF electrodes being integrated into the cover of the drawer.

First claim

The invention claimed is:

1. A PEF cooking appliance, comprising:
a PEF generator; and
a carrier configured to receive a storage container for food, said carrier including at least two PEF electrodes spaced apart to enable insertion of the storage container there between, at least one the PEF electrodes being connected to the PEF generator, said carrier being embodied as a drawer with a top cover pivotably attached thereto, said drawer including a base, with one of the two PEF electrodes being integrated into the base of the drawer and another one of the two PEF electrodes being integrated into the cover of the drawer.

2. The PEF cooking appliance of claim 1 , wherein the other one of the two PEF electrodes is the at least one PEF electrode which is connected to the PEF generator.

3. The PEF cooking appliance of claim 1 , wherein at least one of the two PEF electrodes projects from an interior of the cover.

4. The PEF cooking appliance of claim 3 , wherein the at least one projecting PEF electrode is resiliently suspended.

5. The PEF cooking appliance of claim 1 , wherein the drawer is equipped with the PEF generator, which is located in a rear section of the drawer in a pull-out direction of the drawer, said storage container being insertable into a front section of the drawer, with the cover being configured to only cover the front section of the drawer.

6. The PEF cooking appliance of claim 5 , further comprising a detachable electrical plug connection including a plug connection element on a rear side of the drawer, said plug connection establishing in a connected state an electrical connection between the PEF generator and a power supply.

7. The PEF cooking appliance of claim 1 , further comprising a detachable electrical plug connection including a plug connection element on a rear side of the drawer, said plug connection establishing in a connected state an electrical connection between a housing of the PEF generator and the other one of the two PEF electrodes.

8. The PEF cooking appliance of claim 1 , wherein the cover is configured and arranged on the drawer such that the cover is noticeably openable only when the drawer is fully extended, and further comprising a housing configured to receive the drawer and having an insertion opening for passage of the drawer, and a stop provided on an upper edge of the insertion opening in relation to the cover.

9. The PEF cooking appliance of claim 1 , wherein the drawer comprises a monitoring sensor for monitoring a closure state of the cover.

10. The PEF cooking appliance of claim 1 , further comprising a grounded housing and an electrically conductive pull-out system, wherein the drawer is connected to the housing by way of the electrically conductive pull-out system, said one of the two PEF electrodes being connected to the grounded housing by way of the electrically conductive pull-out system.

11. The PEF cooking appliance of claim 1 , wherein the drawer comprises a sensor for sensing a property of the food.

12. The PEF cooking appliance of claim 1 , wherein the drawer comprises a sensor for sensing fields, voltages and/or currents in the food generated during a PEF treatment.

13. The PEF cooking appliance of claim 1 , wherein the drawer comprises actuator for a non-electrical treatment of food.

14. The PEF cooking appliance of claim 1 , constructed in the form of a household appliance.

15. A PEF cooking system, comprising:
a PEF cooking appliance comprising a PEF generator, and a carrier including at least two PEF electrodes, with at least one the PEF electrodes being connected to the PEF generator, said carrier being embodied as a drawer with a top cover pivotably attached thereto, said drawer including a base, with one of the two PEF electrodes being integrated into the base of the drawer and another one of the two PEF electrodes being integrated into the cover of the drawer; and
a storage container for food, said storage container inserted into the drawer between the at least two PEF electrodes.

16. The PEF cooking system of claim 15 , wherein at least one of the two PEF electrodes projects from an interior of the cover.

17. The PEF cooking system of claim 16 , wherein the at least one projecting PEF electrode is resiliently suspended.

18. The PEF cooking system of claim 15 , wherein the drawer is equipped with the PEF generator, which is located in a rear section of the drawer in a pull-out direction of the drawer, said storage container being insertable into a front section of the drawer, with the cover being configured to only cover the front section of the drawer.

19. The PEF cooking system of claim 18 , further comprising a detachable electrical plug connection including a plug connection element on a rear side of the drawer, said plug connection establishing in a connected state an electrical connection between the PEF generator and a power supply.

20. The PEF cooking system of claim 15 , wherein the cover is configured and arranged on the drawer such that the cover is noticeably openable only when the drawer is fully extended, and further comprising a housing configured to receive the drawer and having an insertion opening for passage of the drawer, and a stop provided on an upper edge of the insertion opening in relation to the cover.
