Abstract

The invention relates to a temperature-preserving electrically heated cooker comprising a body comprising a housing and a container between which a first temperature-preserving chamber is constituted; a lid connected to the upper part of said body; heating means for heating said container; a controller for controlling a heating time and a heating temperature of said heating means; and a base positioned under said body and connected separately thereto. The temperature-preserving electrically heated cooker according to the invention is of a simple structure, and can be used not only to cook, but also to keep the food warm.

Claims

a body comprising a housing and a container between which a first temperature-preserving chamber is constituted;

a lid connected to the upper part of said body;

heating means for heating said container;

a controller for controlling a heating time and a heating temperature of said heating means; and

a base positioned under said body and connected separately thereto.

2. A temperature-preserving electrically heated cooker according to

claim 1

, wherein said cooker further comprises a support under the bottom of the body.

3. A temperature-preserving electrically heated cooker according to

claim 1

, wherein said first temperature-preserving chamber is a vacuum space.

4. A temperature-preserving electrically heated cooker according to

claim 1

, wherein said lid comprises a second temperature-preserving chamber.

5. A temperature-preserving electrically heated cooker according to 1, wherein heating means is a plurality of electrically heating tubes positioned on the outer surface of the container.

6. A temperature-preserving electrically heated cooker according to

claim 5

, wherein said electrically heating tubes are positioned on the bottom or/and on the outer side of the container.

7. A temperature-preserving electrically heated cooker according to

claim 5

, wherein said electrically heating tubes are covered by insulating materials.

8. A temperature-preserving electrically heated cooker according to

claim 1

, wherein a control panel is fixed on the base for setting a heating temperature and a heating time.

9. A temperature-preserving electrically heated cooker according to

claim 2

, wherein said first temperature-preserving chamber is a vacuum space.

10. A temperature-preserving electrically heated cooker according to

claim 2

, wherein said lid comprises a second temperature-preserving chamber.

11. A temperature-preserving electrically heated cooker according to 2, wherein heating means are a plurality of electrically heating tubes positioned on the outer surface of the container.

12. A temperature-preserving electrically heated cooker according to

claim 11

, wherein said electrically heating tubes are positioned on the bottom or/and on the outer side of the container.

13. A temperature-preserving electrically heated cooker according to

claim 11

, wherein said electrically heating tubes are covered by insulating materials.
