Problems solved by technology

There are some problems in the implementation of the above-mentioned existing patented technology, mainly in the integrated design of the product. It is difficult to integrate the design of the elastic element and the design of the outer pot, even if the two are reluctantly integrated. The bottom of the pot is designed to be elastic. Although the elastic bottom of the pot can realize the function of the elastic element, because the elastic element and the outer pot have different requirements on the materials, although the area of ​​the material participating in the elastic deformation is only a small part of the bottom of the outer pot. In order to meet the requirements of the elasti

Example Embodiment

[0029] Example: Take the 20 cm diameter of the inner pot 9 as an example. An aluminum plate with a thickness of about 2.5mm is used to stretch the inner pot 9 into shape, and a number of pressure relief grooves (such as 8) are uniformly arranged along the circumference on the inner side of the pot rim and above the sealing part of the sealing ring 8. The size of each pressure relief groove is: the radial direction of the inner pot 9 is about 4mm, the arc of the circumferential direction is about 5°, and the height dimension (the size extending from the pot along the plane downward) is also the height dimension of the pressure relief loop. It is directly related to the limit value of the highest pressure in the pot, and should be designed in conjunction with the height dimension of the sealing ring 8, the height dimension of the sealing part of the pot cover 1, and the displacement of the elastic element 2 to obtain the required pressure relief value. The sealing ring 8 is made of ...

Abstract

The present invention relates to a movable lid type electric pressure cooker. It is characterized by utilizing elastic lid to control and limit interior pressure of cooker. Said movable lid type electric pressure cooker includes the following several portions: lid, elastic element, switch, sealing ring, inner pot, electric heater and outer pot. Besides, said invention also provides the connection mode of all the above-mentioned portions and the working principle of said electric pressure cooker.

Description

Technical field: [0001] The invention belongs to kitchen appliances, and is a patented technology of electric rice cooker pressurization that controls and limits the pressure in the pot through the elastic displacement of the pot cover. Background technique: [0002] Existing electric rice cooker pressure products (hereinafter referred to as electric pressure cooker) or patented technology, the pressure control scheme mostly adopts the elastic element arranged on a certain part of the outer pot, and the elastic element is used to produce pressure under the action of the inner pressure of the pot. The method of controlling the switch on and off by elastic displacement realizes the closed-loop automatic control of the pressure inside the pot, such as: Chinese invention patent ZL91100026.7 sets the elastic element at the bottom of the outer pot; ZL98100976.X sets the elastic element in the middle of the outer pot; In ZL97100738.1, the elastic element is arranged on the teeth of...
