Abstract

The present invention relates to a cooking hob with a mobile upper part and a stationary or mobile lower part. The upper part includes at least one panel ( 10 ) arranged at its top side. The upper part includes at least one induction coil ( 12 ) arranged below the panel ( 10 ). The upper part includes at least one rechargeable battery ( 14 ). The upper part includes at least one inverter circuit for generating the alternating current for the induction coil ( 12 ). The lower part includes a base plate ( 18 ). The lower part includes a power supply circuit ( 16 ) arranged on the base plate ( 18 ) and connected or connectable to the grid. The upper part is attachable on and removable from the lower part by a user.

First claim

The invention claimed is:

1. A cooking hob with a mobile upper part and a stationary or mobile lower part, wherein:
the upper part includes at least one panel ( 10 ) arranged at its top side,
the upper part includes at least one induction coil ( 12 ) arranged below the panel ( 10 ),
the upper part includes at least one rechargeable battery ( 14 ),
the upper part includes at least one inverter circuit for generating alternating current for the induction coil ( 12 ),
the lower part includes a base plate ( 18 ),
the lower part includes a power supply circuit ( 16 ) arranged on the base plate ( 18 ) and connected or connectable to a power grid, and
the upper part is attachable on and removable from the lower part by a user.

2. The cooking hob according to claim 1 , characterized in, that the cooking hob is a moveable cooking hob.

3. The cooking hob according to claim 1 , characterized in, that the inverter circuit is provided for transmitting a direct current from the battery ( 14 ) and/or from the power supply circuit ( 16 ) into the alternating current for the corresponding induction coil ( 12 ).

4. The cooking hob according to claim 3 , characterized in, that the at least one induction coil ( 12 ) is supplied with a medium voltage, if the inverter circuit is connected to the battery ( 14 ), and the at least one induction coil ( 12 ) is supplied with a high voltage, if the inverter circuit is connected to the power supply circuit ( 16 ).

5. The cooking hob according to claim 1 , characterized in, that the inverter circuit is an integrated part of a corresponding induction coil ( 12 ) of the at least one induction coil ( 12 ).

6. The cooking hob according to claim 1 , characterized in, that the at least one battery ( 14 ) is arranged besides a corresponding induction coil ( 12 ) of the at least one induction coil ( 12 ) and below the panel ( 10 ).

7. The cooking hob according to claim 6 , characterized in, that the power supply circuit ( 16 ) is arranged besides the induction coil ( 12 ) and/or the battery ( 14 ).

8. The cooking hob according to claim 1 , characterized in, that at least one battery ( 14 ) is arranged below a corresponding induction coil ( 12 ) of the at least one induction coil ( 12 ).

9. The cooking hob according to claim 8 , characterized in, that the power supply circuit ( 16 ) is arranged besides the at least one battery ( 14 ).

10. The cooking hob according to claim 1 , characterized in, that the battery ( 14 ) includes at least one lithium-ion-accumulator and/or the battery ( 14 ) bases on metal hydride technology.

11. The cooking hob according to claim 1 , characterized in, that the battery ( 14 ) has a capacity between 0.5 kWh and 2.0 kWh.

12. The cooking hob according to claim 1 , characterized in, that the cooking hob includes at least a second inverter circuit for transmitting direct current from the battery ( 14 ) into the alternating current for the power grid.

13. The cooking hob according to claim 12 , characterized in, that the further inverter circuit is arranged on the lower part of the cooking hob.

14. The cooking hob according to claim 1 , characterized in, that the cooking hob includes at least one power output for supplying external electric and/or electronic devices.

15. The cooking hob according to claim 1 , characterized in, that the cooking hob comprises and/or corresponds with further electric components, like a light system and/or a cooling system.

16. The cooking hob according to claim 1 , characterized in, that at least one heat insulating layer is arranged between the panel ( 10 ) and the at least one battery ( 14 ) in order to avoid overheating of said at least one battery ( 14 ).

17. The cooking hob according to claim 1 , characterized in, that the panel ( 10 ) is a glass ceramic panel.

18. The cooking hob according to claim 1 , characterized in, that the panel ( 10 ) comprises a stainless steel panel.

19. The cooking hob according to claim 1 , characterized in, that the at least one rechargeable battery powers the at least one induction coil.
