Problems solved by technology

It solves the problem of high failure probability and poor control effect when the amount of food in the pot is large when the mechanical program is set between the two-dimensional input flashing switch and the timing axis of the timer used in the existing patented technology; There is a patented temperature-sensing disc valve, which can achieve the function of releasing the air in the pot by adopting the hot sealing method of the sealing ring, and the air is fully released, and the temperature in the pot can reach the high temperature required for pressure cooking , the simplified structure of the product can also reduce the probability of failure and save production costs

Embodiment 1

[0036] Embodiment 1, taking the inner pot 3 with a diameter of 20 cm as an example. The inner pot 3 can be made of an aluminum plate or a stainless steel plate, wherein the thickness of the aluminum plate is about 2.5 mm, and the thickness of the stainless steel plate is about 0.6 mm, and a composite bottom structure is adopted. The outer pot 4 is made of a cold-rolled steel plate with a thickness of 0.6 mm and treated with anti-embroidery. Electric heater 6 can adopt electric rice cooker to replace with electric hot plate, and its power can be about 700W. Except that the bottom of the electric heater 6 and the inner pot 3 need to have a consistent convex shape as in the prior art, the pressure bearing requirements should also be considered. Usually, the radius of the convex ball is smaller than that of the electric cooker. Sealing ring 2 adopts silicon rubber to make, and its shape also can be the same with the shape in the prior patent technology. In order to meet the requ...

Embodiment 2

[0045] Embodiment 2, about the automatic control of pot internal pressure, also can take the mode of one-time control. The one-time control method means that when the pressure in the pot reaches the required cooking pressure, the pressure in the pot will enter the process of reducing the pressure of natural heat dissipation without heating and increasing the pressure. When implementing this cooking method, all take insulation measures to the pot cover 1—add an insulation layer to effectively prolong the depressurization process to meet the actual needs of cooking. In the implementation, only one layer of plastic cover is required to be arranged on the top of the pot cover 1, and its thermal insulation performance can meet the requirement of prolonging the cooking time, and can meet the requirement of beautifying the appearance simultaneously, which can kill two birds with one stone. When implementing the one-time control mode, it is only necessary to change the switch 7 from a...

Embodiment 3

[0047] Embodiment 3, in the above-mentioned implementation, the screw-in fastening method of the flat tooth type pot teeth and the lid teeth can also be changed to the screw tooth type screw-in fastening method. From the above-mentioned known flat-threaded buckling method, there must be a space for falling teeth between the teeth, while the screw-threaded type only needs to increase the lead angle of the screw teeth to exceed the thickness of the pot teeth and two teeth. The height difference between the teeth is greater than the thickness of the teeth, and the screwing of the lid teeth and the pot teeth can be realized. In this embodiment, 6 teeth can still be used, and the chord length of each tooth can be increased by about 1 times compared with the chord length of the flat teeth. The rise angle of each tooth can be selected at about 2°. The screw tooth structure greatly improves the connection strength between the pot teeth and the lid teeth. For the implementation of oth...

Abstract

An electrically heated pressure cooker is composed of cover, sealing ring, internal pot, external pot, electric heater and elastic element. It features that said elastic element arranged between coverand external pot is driven by the pressure in the internal pot to control the power switch, so forming a closed-loop pressure control.

Description

Technical field: [0001] The invention belongs to electric heating pressure cooking utensils for kitchens, and relates to an electric heating pressure cooker. Background technique: [0002] In the Chinese market, a large number of patented technology products of electric heating pressure cookers using a pressure control scheme to control the pressure in the pot have been launched. But some patents such as No. ZL97100738.1 Chinese Invention Patent are relatively complicated in technical structure. The elastic displacement of the tooth can be added to achieve better pressure control effect, and the second is to save raw materials. Although the purpose of saving raw materials has been achieved in practice, the pressure control effect of pressure relief cannot be significantly improved because the elastic displacements of the pot cover and pot teeth are difficult to match each other in practice. This patent adopts the method of setting up a mechanical program between the two-di...
