Description

Cooking device {COOKING APPARATUS}

The present invention relates to a cooking apparatus in which rotation of the inner pot and tilting of the inner pot are stably performed.

In general, an apparatus for automatically cooking food includes a pot for holding the food. Since the pot is heated by a heating device, food inside the pot is heated by a heat source while cooking.

And since the pot is installed in an inclined state and is rotated by a separate driving device, the food inside the pot is also rotated and heated.

Conventionally, a pot for cooking food is installed in an inclined state based on a vertical imaginary line, and the tilt angle of the pot cannot be changed. Therefore, since the conventional cooking apparatus implements only rotation and heating functions, it is difficult to implement frying pan cooking, stir-fried cooking, and soup cooking.

In addition, since a separate device for supporting the inner pot is not provided when the inner pot is rotated, durability of parts is deteriorated due to friction generated when the inner pot is rotated.

The background art of the present invention is published in Japanese Unexamined Patent Publication No. 2004-267519 (published on September 30, 2004, title of the invention: rotary electromagnetic induction heating device).
