Problems solved by technology

[0005] The disadvantage of this control method is that the mechanical amplification factor of the seesaw lever mechanism is not stable enough, so that the displacement variation of the sealed pressure valve 12, that is, the parameter reflecting the pressure in the pot, cannot be stably and accurately transmitted to the induction device 14 , resulting in a large control error

Embodiment 1

[0062] Such as figure 2 As shown, an electric pressure cooker of the present invention includes a pot body 1 and a pot cover 2 . A control circuit 3 is set in the pot body 1, and a pressure transmission device 4 and an elastic sealing sleeve 5 are set on the pot cover 2; Figure 4 As shown, the elastic sealing sleeve 5 is oval, and its lip edge 5a is fitted on the hole wall of the first hole 21 of the pot cover 2 .

[0063] The above-mentioned pressure transmission device 4 includes a bushing 41, a piston 42, and a rotating member 43, which are important parts of this embodiment. The specific structures of the bushing 41, the piston 42, and the rotating member 43 will be described in detail below.

[0064] Such as image 3 and Figure 4 As shown, the bushing 41 is an elliptical body adapted to the shape and size of the elastic sealing sleeve 5 and is open up and down. The sleeve body 41b of the bushing 41 is embedded and fixed in the elastic sealing sleeve 5, so that the ...

Embodiment 2

[0074] The main difference between this embodiment and Embodiment 1 is that the structure of the pressure transmission device 4 is different. Specifically, it is the difference in the steering mechanism that realizes the conversion of linear motion into rotary motion. Such as Figure 8 and Figure 9 As shown, the outer diameter of the rotating member 43 is substantially consistent with the outer diameter of the piston 42 . Three protruding posts 42d are provided on the top edge of the piston 42; three inclined surfaces 43d corresponding to the protruding posts 42d are provided in the circumferential direction of the lower edge of the rotating member 43. Therefore, when the protruding post 42d of the piston 42 moves linearly up and down, the protruding post 42d pushes the inclined surface 43d at the lower part of the rotating member 43 to slide, thereby driving the rotating member 43 to rotate. This type of transmission is similar to toothed transmission.

Abstract

An electric pressure cooker is composed of a cooker body with control circuit and sensor on its top edge, and a cover with an elastic sealing sleeve and a pressure driver consisting of lining sleeve embedded in said elastic sealing sleeve, an axially moving piston and a rotary part driven by said piston and with fixed long arm and inductor.

Description

technical field [0001] The invention relates to an electric pressure cooker, in particular to an electric pressure cooker with automatic pressure control. Background technique [0002] As a kind of electric cooking utensil, the electric pressure cooker works under high pressure. In order to ensure the safety of the electric pressure cooker, the pressure in the electric pressure cooker must be controlled so that the pressure in the electric pressure cooker does not exceed a certain set value or rated value. [0003] The internal pressure control method of the traditional electric pressure cooker, such as the Chinese invention patent named "Fully Sealed Automatic Multifunctional Electric Cooker" and the application number 91100026.7, mainly adopts the rigid structure of "mouth". value, the inner pot of the electric pressure cooker expands and deforms under high pressure, and is forced to move down. This deformation can drive the deformation of the elastic part at the bottom of...
