Abstract

A stirrer in the form of a stripe is installed on an inner wall of a cylindrical pot of food stirring apparatus, a width of a scrape-up surface is formed to be narrower from an opening side of the cylindrical pot toward a bottom thereof, and a projection is provided on an outer edge side of the scrape-up surface.

In the food stirring and cooking apparatus which rotatably supports the cylindrical pot in which a stirrer is provided on the inner wall thereof, not only rotational operation along the edge of the cylindrical pot but also longitudinal rotational operation from the opening side of the pot to the bottom and from the bottom to the opening side are applied to food so that the food is turned and stirred whereby increasing the food stirring effect.

When the cylindrical pot is rotated, the food put into the cylindrical pot moves in the direction reversed to the rotational direction of the pot due to its own weight and is scraped up by the stirrer. At this time, since the projection is provided on the outer edge side of the scrape-up surface of the stirrer, the food is supported by the projection, without immediately falling the inner wall surface of the pot, and moves down toward the bottom of the pot The food not only rotates along the edge of the cylindrical pot but also rotates in the longitudinal direction from the opening side to the bottom of the pot

Claims

1. a food stirring apparatus comprising:

a rotatably mounted cylindrical body having an arched bottom, an inner wall and an opening opposite of the arched bottom; and

a stirring member mounted to the inner wall in an axial direction, the stirring member having an outer edge defining a scrape-up surface, the stirring member having an outer edge defining a scrape-up surface, the stirring member having a substantially triangular-shaped vertical cross-section, the stirring member also having a width which gradually narrows from the opening to the bottom of the body.

2. The food stirring apparatus according to claim 1, wherein the stirring member is mounted to the inner wall on an angle with respect to the axis of the body.

3. The food stirring apparatus according to claim 1, including heating means for heating the body and a second stirring member mounted to the inner wall opposite of the first stirring member.

4. The food stirring apparatus according to claim 1, including vapor removal means at a central portion of the arched bottom of the body.

5. The food stirring apparatus according to claim 1, including inclined support means for inclining the body.

6. The food stirring apparatus according to claim 1, wherein the stirring member comprises a mounting portion mounted to the inner wall, the mounting portion having an upper portion and a projection mounted to the upper portion of the mounting portion.

7. The food stirring apparatus according to claim 6, wherein the scrape-up surface faces a direction opposite of a direction of rotation for the body.
