Heat-storing constant-pressure electric pressure cooker

Abstract

The heat-accumulating constant pressure type electric pressure cooker consists of mainly cover, outer casing, outer pot, inner pot, heating and energy accumulating tray, pressure release valve, cover locking mechanism, control circuit system and other parts. The heating and energy accumulating tray consists of casing, heating layer with heating resistor wire and heat accumulating insulation layer, and is installed via one installation board to the bottom of the cooker. The electric pressure cooker has simple on-off type control circuit system, outer pot with rigid bottom, and temperature inducing controlled pressure switch. The electric pressure cooker has simple structure, low cost, high reliability, high safety, low power consumption, environment friendship and other advantages. With constant pressure, the electric pressure cooker has its cooked food possessing good taste.

Description

Technical field

[0001] The invention relates to an electric pressure cooker, in particular to a heat storage constant pressure electric pressure cooker. technical background

[0002] At present, the electric heaters of general electric pressure cookers all use the resistance wire to be fixed in a metal tube with insulating and heat-conducting materials, and then the metal tube and the bottom heating plate are processed as one by die-casting technology, and the heating plate is directly heated by the principle of heat conduction. Its main disadvantages are manifested in the following aspects: 1. Most of the heat generated by the lower part of the heating plate and its surroundings is dissipated in the external environment, and the heat utilization rate is low; 2. When the heating object is heated to a certain temperature, the heating plate is turned off after the power is turned off The temperature drops quickly, and the pressure holding performance is poor. If heat preservat...
