Abstract

The invention relates to a handle for a cooking vessel or lid that includes at least one thermoelectric generator. The invention is characterized in that the handle has a releasable locking device and the thermoelectric generator has at least one first contact surface thermally connected to a thermal coupling part that comes into contact under stress with a portion of the cooking vessel or lid when the releasable locking device of the handle is in a locked position on the cooking vessel or lid.

First claim

The invention claimed is:

1. A handle for a cooking vessel or lid that comprises at least one thermoelectric generator, wherein the handle comprises a releasable locking device and the thermoelectric generator comprises at least a first contact surface connected thermally to a metal thermal coupler, which comes into contact under pressure with a section of the cooking vessel or lid when the releasable locking device of the handle is in a locked position on the cooking vessel or lid, wherein the releasable locking device comprises a tightening part that squeezes the vessel or lid, wherein movement of the tightening part is initiated by one or more activation buttons, wherein the handle comprises a hollow body with a cavity having one or more intake holes and one or more output holes in communication with the cavity, wherein the one or more intake holes and the one or more output holes are configured for cooling the heat sink, and wherein the thermoelectric generator, a heat sink, and at least a portion of the releasable locking device are contained within the cavity.

2. The handle for a cooking vessel or lid according to claim 1 , wherein the thermoelectric generator comprises a second contact surface, connected thermally to a connection part.

3. The handle for a cooking vessel or lid according to claim 2 , wherein the heat sink is connected thermally to the connection part or directly to the second contact surface of the thermoelectric generator.

4. The handle for a cooking vessel or lid according to claim 3 , wherein the heat sink is comprised of one or more fins that are shorter in length than the handle.

5. The handle for a cooking vessel or lid according to claim 4 , wherein the fins are made of a heat-conductive material.

6. The handle for a cooking vessel or lid according to claim 4 , wherein the fins are heat pipes.

7. The handle for a cooking vessel or lid according to claim 3 , wherein the heat sink is comprised of a radiator comprising at least two fins assembled vertically and parallel to one another, to obtain convection cooling.

8. The handle for a cooking vessel or lid according to claim 3 , wherein the heat sink is a latent heat sink comprised of a solid body with a melting point of between 50° C. and 70° C.

9. The handle for a cooking vessel or lid according to claim 8 , wherein the handle comprises a heat diffuser.

10. The handle for a cooking vessel or lid according to claim 1 , wherein the handle comprises an electronic device connected to the thermoelectric generator.

11. The handle for a cooking vessel or lid according to claim 10 , wherein the electronic device may be an electronic display or an electronic sensor.

12. The handle for a cooking vessel or lid according to claim 1 , wherein the handle comprises a micro-fan connected to the thermoelectric generator.

13. The handle for a cooking vessel or lid according to claim 1 , wherein a total surface area of the one or more intake holes is larger than a total surface area of the one or more output holes.
