Abstract

Some embodiments provide a multi-purpose cooking and heating container. The container can be used with a variety of different cooking appliances, including a microwave oven, induction cooker, electric stove, etc. The multi-purpose container is double layered in that it has inner and outer shells. The inner shell is disposed adjacent the outer shell, and the outer edges of the shells are then hermetically sealed to form an inner space between the two shells. To transfer heat to the inner space in different cooking environment, the container'"'"'s outer surface of the outer shell is coated with an exothermic enamel glaze or a exothermic ceramic coat.

Claims

1. A multi-purpose container comprising:

inner shell;

outer shell,

wherein the inner shell is disposed adjacent the outer shell, and outer edges of the shells are hermetically sealed to form an inner space between the two shells,

wherein, to transfer heat to the inner space with different types of cooking appliances, the outer surface of the outer shell is coated with an enamel glaze or a ceramic coat that is blended with exothermic particles; and

a safety valve installed on a hole formed on the side of the outer shell to discharge excess pressure within the inner space when the vessel is heated with one of the appliances.

2. The multi-purpose container of claim 1, wherein the container is a doubled-layered pot, a double-layered pan, a double-layered cup, or a double-layered travel mug.

3. The multi-purpose container of claim 1, wherein the ceramic coat is an exothermic ceramic coat that includes ceramic coating blended with iron oxide (Fe2O3) powder, Manganese (Mn) and Zinc (Zn) powder, and silica powder.

4. The multi-purpose container of claim 1, wherein the enamel glaze is an exothermic enamel glaze that includes Fe2O3 powder, ferrosilicon (Fe—

Si) powder, aluminum silicate powder, and ethylene glycol.

5. The multi-purpose container of claim 1 further comprising a piece of high-heat resistant material that is wrapped around the outer surface of the inner shell to trap heat in the inner space and insulate the container.

6. The multi-purpose container of claim 5, wherein the high-heat resistant material is a piece of ferrite rubber comprising silicone rubber mixed with Fe2O3 powder, Mn and Zn powder, and silica powder.

7. The multi-purpose container of claim 1 further comprising a heating plate that is in contact with at least one of the inner bottom surface or inner bottom face of the outer shell and the outer bottom surface or the outer bottom face of the inner shell.

8. The multi-purpose container of claim 7, wherein the heating plate is a cordierite ceramic plate.

9. The multi-purpose container of claim 7, wherein the heating plate comprises a fluid path to allow heat to circulate along the bottom of the inner space.

10. The multi-purpose container of claim 1, wherein the outer shell is made with at least one ply of magnetic stainless heel, aluminum, or copper.

11. The multi-purpose container of claim 1 further comprising an exothermic heating plate that is in contact with the bottom face of outer shell.

12. The microwave cooking apparatus of claim 11, wherein the exothermic heating plate comprises Fe2O3 powder, Mn and Zn powder, and silica powder that is blended with ceramic powder.

13. The multi-purpose container of claim 12, wherein the heating plate is formed by mixing the powders, compressing the powders using high heat pressure to form a compressed plate, and, in order to reinforce the compressed plate, wrapping or weaving the plate with fibrous material.

14. The multi-purpose container of claim 1, wherein the fibrous material is ceramic wool.

15. The multi-purpose container of claim 1 further comprising a micro-porous insulation panel or an insulating mat in the inner space.

16. The multi-purpose container of claim 1 further comprising a lid that is coated with the same exothermic enamel glaze or exothermic ceramic coat.

17. The multi-purpose container of claim 1, wherein the lid is formed to operate as a heating or cooking container.
