A pressure-controlled electric pressure cooker

Abstract

The invention discloses a pressure-controlling electric pressure cooker. A pot cover, a sealing ring, an inner pot and an outer pot are sequentially connected to form a sealing body, and several disc springs with opening grooves are arranged between the heating plate and the outer pot. The small-diameter end of the disc spring faces the inner horizontal flanging to form an upper support ring, the large-diameter end of the disc spring forms a lower support ring, and the cone wall between the upper support ring and the lower support ring forms an elastic deformation zone, radially through the upper The support ring extends to the cone and is provided with a cross-shaped open slot whose contour line projected on the horizontal plane. From the notch of the open slot to the bottom of the slot, it has a gradually expanding structure, and the lower support ring is supported on the bottom of the outer pot. , the upper support ring leans against the feet of the heating plate, and the feet and disc springs are positioned and connected to the outer pot as a whole through fixing screws. The disc spring it has effectively increases the amount of elastic deformation, which is beneficial to the pressure detection device to sense pressure changes, thereby improving the pressure control accuracy and safety and stability.

Description

technical field [0001] The invention relates to the technical field of kitchen cooking appliances, in particular to a pressure-controlling electric pressure cooker. Background technique [0002] At present, in the cooking utensil industry, cooking electric pressure cookers that can automatically adjust the pressure are generally adjusted by assembling elastic parts, and the elastic deformation of the elastic parts between the heating plate and the outer pot is used to generate corresponding displacements for precise pressure control. . However, the elastic parts used in the electric pressure cookers of the prior art are usually flat elastic plates. Although the structure is simple and easy to process, the relative displacement provided by the elastic deformation of the flat elastic parts is small, and the pressure control accuracy is low. When the pressure is too large When the deformation is large, it will cause a large attenuation and it is difficult to reset, resulting i...
