Pressure control method and apparatus of electric pressure cooker, and electric pressure cooker

Abstract

The present invention provides a pressure control method and apparatus of an electric pressure cooker, and the electric pressure cooker. The method comprises a detection step that a temperature wrap disposed at the bottom of the electric pressure cooker detects temperature of the electric pressure cooker; and a heating device control step of controlling on and off of a heating device according to the temperature detected by the temperature wrap when a pressure switch is off, specifically, opening the heating device to heat when the temperature is less than or equal to first temperature, and closing the heating device and stopping heating when the temperature is great than or equal to second temperature, wherein the second temperature is greater than the first temperature, the first temperature is great than or equal to 100 DEG C and less than or equal to 108 DEG C, and the second temperature is great than or equal to 102 DEG C and less than or equal to 110 DEG C. According to the technical scheme, cycle control of the pressure in a certain range is achieved through a single pressure switch without internal temperature-sensitive monitoring, and use functions of the electric pressure cooker are improved.

Description

technical field [0001] The invention relates to the field of control, in particular to a pressure control method and device for an electric pressure cooker and the electric pressure cooker. 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. Sealed cooking, pressure continuously adjustable, completely solve the safety problem of pressure cooker, remove the safety hazards that have plagued consumers for many years in ordinary pressure cookers; its thermal efficiency is greater than 80%, saving time and electricity (more than 30% more than ordinary rice cookers) . [0003] The work of the electric pressure cooker is divided into heating process, pressure maintaining process and heat preservation project. After the electric pressure cooker is heated to a certain temperature (or pressure), it enters the pressure maintaining p...

AI Technical Summary

Problems solved by technology

[0005] The main purpose of the present invention is to solve the above-mentioned problems of the prior art, and propose a method, device and electric pressure cooker for controlling the pressure of an electric pressure cooker, so as to solve the problem of only having a bottom temperature sensing package and a single pressure switch in the prior art. It is difficult to realize the control of multiple pressures, and improve the use function of the electric pressure cooker
