Problems solved by technology

[0002] Most of the existing electric pressure cookers with automatic voltage regulation use the deformation of the elastic parts installed between the heat preservation cover and the electric heating plate to realize the relative displacement between the electric heating plate and the heat preservation cover. One of the elastic parts is a disc-shaped structure. The elastic part has the advantage of large pressure bearing capacity, but there is a disadvantage that the elastic part cannot recover when the pressure is too large; another structure adopts the scheme of adding a stacked spring-like elastic support device at the bottom of the heat preservation cover, as disclosed in Chinese patent application number CN200910231276.X The elastic support device is equipped with a heating plate above the bottom of the heat preservation cover, and multiple sets of elastic support structures are arranged between the heating plate and the bottom of the heat preservation cover. The elastic support structure includes a stacked spring-shaped elastic plate and a base. The advantage of high precision, but because the elastic support structure includes a stacked spring-shaped elastic plate and a base, the assembly is complicated, and the cost of the stacked spring-mounted elastic plate is also high, which has caused troubles to further reduce the cost of the electric pressure cooker

Abstract

The invention discloses a voltage-controlled electric pressure cooker, which comprises a pot body, a pot cover, a control circuit and a pressure detection device. The bottom of the heating plate is provided with a plurality of legs and is installed on the bottom of the heat preservation cover through the legs. The inner pot is placed on the heating plate, and the inner pot and the heating plate can be displaced together in the heat preservation cover. The plurality of legs and Between the bottom of the heat preservation cover, there are elastic parts and reinforcement parts to increase the strength of the heat preservation cover. Under the same pressure, the sinking amount of the feet connected to the elastic parts of the heating plate is greater than that of the legs connected to the reinforcement parts. Pressing the electric pressure cooker triggers the deformation of the elastic parts. , the inner pot and the heating plate sink to the side of the elastic member. Therefore, the structure of the present invention has the advantages of high flexibility and low cost.
