Electric cooking device

Abstract

The invention discloses an electric cooking device. The electric cooking device comprises a pot body in which a cooking cavity is formed, a pot cover which is arranged on the pot body for opening or closing the cooking cavity and in which a plurality of pressure relief openings with different areas are formed, a plugging structure which is arranged on the pot cover, a plurality of sealing deviceswhich are used for sealing the corresponding pressure relief openings, and a driving device which is used for driving the plugging structure to move above any one of the pressure relief openings to seal the pressure relief opening, wherein the sealing device of the pressure relief opening sealed by the sealing structure is in the open position and the rest sealing devices are in the sealing position of sealing the corresponding pressure relief openings. In this way, the electric cooking device can change the pressure in the cooking cavity, so that the food can be tumbled under the pressure difference and heated more uniformly.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to an electric cooking device. Background technique [0002] In the related art, cooking utensils generally use a fixed pressure (such as 1.3 times or 1.7 times the atmospheric pressure) to cook in order to achieve uniform heating of the cooking food so that the food is fully heated during the heating process, but this type of product usually boils when cooking. The stage pressure is maintained at a fixed value. Since there is no change in pressure, the food in the cooking utensil still has the problem of uneven heating, so the food is easy to coagulate into blocks. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes an electric cooking device, which can change the pressure in the cooking cavity, so that the food can be rolled unde...
