Abstract

An induction stove assembly that utilizes pads between the cook-top of the stove and cooking vessels placed on the stove for heating. The pads are easily removable and interchangeable with other similar pads. The pads help protect the cook-top from damage, make clean-up more efficient, and insulate the cook-top from excessive heating.

Claims

1. An induction stove assembly, the assembly comprising:

a cook-top;

an induction cooking zone above the cook-top;

a temperature sensor adjacent the induction cooking zone; and

a pad adapted to be placed on the cook-top such that its removal from the cook-top is not impeded and adapted to receive a cooking vessel placed in the induction cooking zone;

wherein the pad comprises a thermally insulating portion and a thermally transmissive member;

wherein the thermally transmissive member is formed from a material having a higher thermal conductivity than a material of which the thermally insulating portion is formed; and

wherein said thermally transmissive member is disposed in an opening in the thermally insulating portion of the pad and is adapted to transmit heat from the cooking vessel to the temperature sensor.

2. The assembly of claim 1, wherein the temperature sensor is disposed beneath the cook-top.

3. The assembly of claim 2, wherein the thermally transmissive member is disposed in the thermally insulating portion such that an uppermost surface of the thermally transmissive member is substantially flush with an uppermost surface of the thermally insulating portion and a lowermost surface of the thermally transmissive member is substantially flush with a lowermost surface of the thermally insulating member.

4. The assembly of claim 3, wherein the surface area of the uppermost and lowermost surfaces of the thermally transmissive member are less than 10% of the total surface area of the pad.

5. The assembly of claim 2, wherein the thermally transmissive member is comprised of aluminum.

6. The assembly of claim 1, wherein the thermally transmissive member is composed of a material having a thermal conductivity of 1 W/(m·

K) or greater.

7. The assembly of claim 1, wherein the thermally transmissive member is composed of a material having a thermal conductivity of 10 W/(m·

K) or greater.

8. The assembly of claim 1, wherein the thermally transmissive member comprises a first part and a second part that are secured together by a threaded connection.

9. The assembly of claim 1, wherein the widest portion of the thermally transmissive member has a diameter of about 0.5 inches.

10. The assembly of claim 1, wherein the thermally insulating portion of the pad is formed of silicone rubber.

11. The assembly of claim 1, wherein the pad is sized to substantially correspond to the size of the induction cooking zone.

12. The assembly of claim 1, wherein the assembly is portable.
