Heating container and electric rice cooker

Abstract

The invention discloses a heating container, which comprises an inner container which is provided with an accommodating cavity for containing a substance to be heated and an opening; a heat-conductingshell which sleeves outside the inner container; the inner container is sealed with the top of the heat-conducting shell to form a heating cavity; the heating cavity is internally provided with a liquid-absorbing core containing a phase-change heat-conducting material; when the heat-conducting shell is heated and the working temperature of the phase-change heat-conducting material is reached, thephase-change heat-conducting material undergoes a phase change and releases heat to heat the inner container. The invention also discloses an electric rice cooker with the heating container. By usinga brand-new technology route, the surrounding and uniform heating of the whole inner container is achieved without using an IH heating mode, and the device has the advantages of simple structure, lowcost, high safety level and no electromagnetic radiation.

Description

technical field [0001] The invention relates to the field of electric appliances. More specifically, the present invention relates to a heating container and an electric rice cooker. Background technique [0002] The heating method of the traditional electric rice cooker is heating with a heating plate. The principle is to conduct heat to the bottom of the inner pot through the heating plate, and then transfer the heat to the ingredients from the inner pot. This heating method is low in production cost and less difficult to control, but the heating Inhomogeneous, precise temperature control is not possible, which is also the obvious disadvantage of this heating method. IH (Electromagnetic Heating) technology improves this disadvantage. It relies on the magnetic field line to penetrate the pot body for heating. During the heat conduction process, the temperature rises rapidly, and many high-end IH rice cookers introduce multi-level coils to realize the surrounding heating o...

AI Technical Summary

Problems solved by technology

But the current IH rice cooker technology has deficiencies: 1. IH technology increases the cost of the rice cooker, and the price rises to the range of 1000-2000 yuan. Therefore, the market expansion of IH rice cooker is slow; 2. IH electric heating has electromagnetic radiation. The high-frequency current used by electromagnetic heating has a frequency of 15-20kHz. When it is used at high power, there is still electromagnetic radiation, which is not good for pregnant women, children and other people; Gallbladder (kettle), increased cost and weight; 4, when heating temperature is too high, IH electric cooker has no other safety measures except alarm
