Embodiment approach

[0092] A specific embodiment of the present invention combines various aspects of other specific embodiments of the present invention. A pressure control device for an electric pressure cooker further includes a timing unit (not shown in the figure) and an interruption unit (not shown in the figure).

[0093] The timing unit is used to count the working time of the control unit of the heating device.

[0094] The first pressure switch control unit works in a cyclic state, cyclically changing between the first pressure and the second pressure.

[0095] The interruption unit interrupts the operation of the heating device control unit when the working time is greater than or equal to the first time threshold.

[0096] Set or adjust the first time threshold according to the parameters of the electric pressure cooker and the content of the execution work, and when the execution time of the first pressure switch control step reaches the first time threshold, the work of the heating...

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...
