Pressure cooking utensil and control method thereof

Abstract

The invention discloses a pressure cooking utensil. The pressure cooking utensil comprises an inner pot and a pot lid which together form a heating cavity, as well as a heater used for heating up the inner pot, a cooler used for cooling down the inner pot and / or the pot lid, a float-actuated valve, locking components and a controller, wherein after the float-actuated valve rises to close an exhaust passage of the pressure cooking utensil, the locking components lock the float-actuated valve to seal the heating cavity; and the controller is connected with the heater and the cooler respectively and controls the cooler to cool down the inner pot and / or the pot lid to enable negative pressure to be generated in the heating cavity. The pressure cooking utensil can conduct fresh preservation on food in the pot after cooking the food so as to meet the living needs of people and bring convenience for users. The invention also discloses a control method of the pressure cooking utensil.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a pressure cooking appliance and a control method for the pressure appliance. Background technique [0002] Electric pressure cooker is an upgraded product of traditional pressure cooker and electric rice cooker. It combines the advantages of pressure cooker and electric rice cooker, adopts new technologies such as elastic pressure control, dynamic sealing, external screw cover, electric switch with adjustable displacement, and can be fully sealed. Cooking, the pressure can be continuously adjusted, which relieves the safety hazards that have plagued consumers for many years in ordinary pressure cookers. In addition, the thermal efficiency of the electric pressure cooker is greater than 80%, saving time and electricity (more than 30% more than ordinary rice cookers). Therefore, it has the incomparable advantages of other cooking utensils. It can meet various cooking...
