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...

Embodiment

[0029] Embodiment: Take the caliber 20cm of the inner pot 9 as an example. Adopt the aluminum plate of thickness 2.5mm, inner pot 9 is stretched and formed, on the inner side of its pot edge, the top of sealing ring 8 sealing positions, along the circumference evenly arrange some pressure relief grooves (as 8). The size of each pressure relief groove is: the radial direction of the inner pot 9 is about 4mm, the arc in the circumferential direction is about 5°, and the height dimension (the dimension extending downward from the pot along the plane) is also the height dimension of the pressure relief ring line. It is directly related to the limit value of the maximum pressure in the pot, and should be designed in conjunction with the height of the sealing ring 8, the height 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 high-quality silicon rubber, and its sealing d...
