Description

Cooking utensil Technical Field The present utility model relates to a cooking appliance. Background Currently, spring valves used in pressure cooking appliances on the market achieve sealing and exhaust control of the pressure valve. The spring valve is usually controlled by a solenoid valve or a stepping motor to drive a control mechanism to control the opening or closing of the pressure valve, so that the exhaust gas is accurately regulated. When the solenoid valve is used for controlling the spring valve, the stroke and thrust requirements of the solenoid valve are very strict. In the operation of the pressure cooking appliance, the solenoid valve needs to be continuously operated, and because the operating environment temperature is high, the solenoid valve is required to be made of materials with good temperature resistance and insulation performance. The manufacturing cost of the electromagnetic valve is greatly increased, the overall production cost of the pressure cooking utensil is further improved, and the competitiveness of the product in the market is limited. The adoption of the stepping motor to control the spring valve can effectively solve part of problems existing in the electromagnetic valve control scheme, for example, the stepping motor has better control precision and stability, but has higher cost. The high-cost stepping motor can also cause the rise of the production cost of the pressure cooking appliance, which is not beneficial to the popularization of products. Accordingly, there is a need to provide a cooking appliance to at least partially solve the above-mentioned problems. Disclosure of utility model In the summary, a series of concepts in a simplified form are introduced, which will be further described in detail in the detailed description.
