Cooking utensil with pressure control structure

Abstract

The invention discloses a cooking utensil with a pressure control structure. The cooking utensil comprises a container for containing food and a cover body arranged on the container in a covering manner; the cooking utensil is characterized in that a first pressure release valve and a second pressure release valve are arranged on the cover body; the first pressure release valve is used for maintaining a working internal pressure in the container to be in a high-pressure environment; the first pressure release valve is arranged to act and release gas in the container to an external space when the working internal pressure in the container is higher than a pressure threshold value, so that the high-pressure working environment is maintained in the container, wherein the pressure threshold value is higher than the atmospheric pressure of the external space; the second pressure release valve is used for releasing the gas in the containing container to the external space; and under the synergistic effect of the first pressure release valve and the second pressure release valve, liquid in the container can be bumped, so that the food in the container can be stirred to be uniformly heated, and the taste is optimized.

Description

Technical field [0001] The invention relates to a cooking appliance containing a pressure control structure, which is beneficial to optimize the uniform heating of food. Background technique [0002] IH electromagnetic heating rice cooker is one of the more popular rice cookers on the market. The IH electromagnetic heating rice cooker uses the eddy current heat generated by the inner pot induction heating coil to cook the food contained in the inner pot. However, since the inner pot heats up to heat the food, the food in the area close to the inner pot wall is heated sufficiently, but the food in the central area away from the inner pot wall is not heated enough. In order to enable the food to be heated evenly, Chinese invention patent CN03149178.2 discloses a rice cooker, which is characterized by having: a pot containing water and rice to be cooked, and heating the inside of the pot. A heating device for cooking rice, a lid that blocks the opening of the pot, and a pressure w...
