Description

technical field [0001] The invention is applied to the technical field of cooking tools, and in particular relates to a pressure cooker cover structure with a pressure display and alarm function, a pressure cooker and a use method. Background technique [0002] The pressure cooker is a cooking tool widely used in daily life. The pressure cooker uses the physical phenomenon that the boiling point of the liquid rises under higher pressure. By increasing the pressure in the pot, the water can reach a higher temperature without boiling. Food is heated to more than 100 degrees Celsius to speed up the efficiency of stewing food. [0003] During the working process of the pressure cooker, we have no way of knowing the temperature and pressure state in the pot. Sometimes we leave the kitchen to do other things and forget to check when the pressure cooker is cooking food, especially the open flame pressure cooker, which may burn the food for a long time When there is a lot of food i...

[0003] During the working process of the pressure cooker, we have no way of knowing the temperature and pressure state in the pot. Sometimes we leave the kitchen to do other things and forget to check when the pressure cooker is cooking food, especially the open flame pressure cooker, which may burn the food for a long time When there is a lot of food in the pot or when cooking beans, porridge and other granular or easy-to-froth foods, the food particles will block the vent valve and cause the high-pressure gas in the pot to be unable to discharge, and the pressure in the pot will continue to rise, causing certain security risks
