Direct-current double-layer pressure feedback pressure cooker and control method thereof

Abstract

The invention relates to the technical field of pressure cookers, in particular to a direct-current double-layer pressure feedback pressure cooker and a control method thereof. By the aid of a sealed inner container and a sealed outer container, the outer container can function in sharing pressure, so that the pressure intensity between the inner container and the outer container is higher than that of the outside, the pressure intensity in the inner container is higher than that between the inner container and the outer container, the manufacturing temperature of main food and subsidiary food is increased, heat efficiency is improved, and the pressure cooker is suitable for a common area and can meet the manufacturing requirements of main food and subsidiary food of a high-altitude area. In addition, the pressure of the inner container is detected through a pressure sensor and fed back a control circuit, current of a heater is adjusted through the control circuit, so that a pressure value of the inner container is stabilized within a set range, the relative stability of the temperature of the inner container is kept, energy consumption is reduced, and manufacturing quality is improved.

Description

technical field [0001] The invention relates to the technical field of pressure cookers, in particular to a direct-current double-layer pressure feedback pressure cooker. Background technique [0002] Electric pressure cooker is a commonly used cooking utensil. Generally, the pressure inside the cooker is directly controlled through the safety valve. The disadvantage of this pressure control method is that the pressure value is single, and while the pressure is released, the electric energy continues to provide energy and generate new steam, making the inside of the pressure cooker The pressure remains constant and the energy consumption is high. On the other hand, the pressure cooker of the prior art generally includes an inner container and an outer container. The interlayer in between is only used as the shell to support protection and heat insulation, so that the pressure value in the inner tank is limited by the strength of the inner tank, so that the temperature in t...

[0002] Electric pressure cooker is a commonly used cooking utensil. Generally, the pressure inside the cooker is directly controlled through the safety valve. The disadvantage of this pressure control method is that the pressure value is single, and while the pressure is released, the electric energy continues to provide energy and generate new steam, making the inside of the pressure cooker The pressure remains the same, the energy consumption is high

On the other hand, the pressure cooker of the prior art generally includes an inner container and an outer container. The interlayer in between is only used as the outer shell for support, protection and heat insulation, so that the pressure value in the inner tank is limited by the strength of the inner tank, so that the temperature in the inner tank cannot be further increased.
