Embodiment Construction

[0004] 1. Install a temperature sensor inside the lid of the pressure cooker and connect it to the circuit board at the bottom of the pot. 2. The lower part of the pressure cooker is no longer equipped with a mechanical pressure adjustment switch. When the temperature in the pot rises to a certain value (that is, the corresponding pressure), the electric heating plate stops heating, and when the temperature in the pot drops to a certain value (that is, the corresponding pressure), the electric heating plate resumes heating, and the cycle goes back and forth to achieve the purpose of maintaining pressure. 3. According to the type of cooking food, the pressure can be set on the control panel at will, and the control is flexible and accurate. Factory assembly and aftermarket repairs require no pressure adjustments. Saves the cumbersome pressure adjustment process. Improve work efficiency and improve product reliability. Upgrade from mechanical pressure regulation to electronic...

Abstract

A pressure control method of an electronic pressure cooker includes using a temperature sensor to acquire change of the temperature of the cooker according to a relation between the temperature of the cooker and the pressure; converting the change of the temperature into the change of the pressure; and completing control of the pressure of the cooker through a circuit. An electronic temperature sensor is used to replace a mechanical pressure switch, the regulation control is accurate, and the failure rate is low.

Description

technical field [0001] The invention relates to the field of electric pressure cookers. Specifically, it is a pressure control method for an electric pressure cooker. Background technique [0002] The pressure control mode of the existing pressure cooker is to install a mechanical pressure switch under the pot body. When the pressure in the pot increases, the inner tank of the pot will press the heating plate to move downward with the increase of pressure. When the set value is reached, the contact of the pressure switch will be disconnected and the heating will stop. When the pressure in the pot decreases, the electric heating plate is displaced upward by mechanical force. When it drops to the set value, the contact of the pressure switch is closed, the heating plate is heated, and the cycle goes back and forth to achieve the purpose of maintaining pressure. This way of pressure adjustment is cumbersome and has a high failure rate. Contents of the invention [0003] T...
