Embodiment Construction

[0025] The electric rice cooker consists of a shell 8, an outer heat insulation cover 9, a middle heat insulation cover 10, an inner heat insulation cover 11, thermal insulation cotton 12, an electric heating tube 13, a base 14, a temperature sensing head 15, a drain pipe 16, and an upper connecting ring 7. Inner pot 6, inner cover 5, sealing silicone ring 4, temperature control fixed metal heat conduction plate 3, temperature control device 2, pot cover 1 and steam vent 17, etc. Between the pot cover 1 and the inner cover 5, there is a temperature-controlling fixed metal heat-conducting plate 3, and the temperature-controlling fixed metal heat-conducting plate 3 is fastened on the pot cover 1 with screws. A concave platform is arranged in the center of the temperature-controlling fixed metal heat-conducting plate 3, and a temperature control device 2 is riveted on the concave platform. The temperature sensing surface of the temperature control device 2 is in close contact wit...

Abstract

An electric rice cooker is composed of top cover, internal pot, heater, thermal insulating unit and temp control system. It features that the gap between internal pot and heater is greater than zero, a radiation cavity consists of internal pot and thermal insulating unit, and a detector of said temp control system is arranged in said top cover. Its advantage is use of measuring temp at top for heating uniformly.

Description

technical field [0001] The invention relates to an electric rice cooker, in particular to an electric rice cooker which is mainly heated by heat radiation instead of heat conduction and adopts a steam temperature sensing device at the top. Background technique [0002] At present, the widely used electric rice cooker adopts electric heating plate conduction heating technology. The surface of the metal electric heating plate is all in contact with the bottom of the inner tank for heat transfer, and the temperature control detection directly detects the temperature of the outer wall of the inner tank. For materials with low conductivity coefficient and large difference between expansion coefficient and metal, such as pottery, natural stone and glass, etc., the electric rice cooker made of liner has the following problems in the above-mentioned technical scheme: [0003] 1. Partial overheating, uneven heating of the inner tank, large temperature difference, internal stress, and...
