Problems solved by technology

[0002] At present, the existing purple sand ceramic electric heating pots on the market, in order to solve the problems of low manufacturing and molding precision of the inner pot and improve the thermal efficiency, usually use the method of radiant cavity heating. There are roughly two representative technical solutions, one solution The heat shield and the installation plate are installed in the shell, the installation plate and the heat shield are mechanically connected together, the electric heater is fixed in the heat shield, and the elastic device is set under the installation plate, and the heat shield and the electric heater are placed in the outer pot together. Floating up and down, a radiant heating chamber is formed between the heat shield and the inner pot, and a protective cover net assembly is arranged above the electric heater, such as the Chinese patent CN200980173Y. This structure is characterized by a compact structure, but due to the fact that the electric heater The center floats up and down with the heat shield, which brings hidden dangers to electrical safety. The electrical connection of the electric heater is unreliable, and the protective mesh cover, heat shield, and mounting plate are connected by a relatively complicated mechanical connection, which poses a threat to the heating structure. Inconvenient assembly and disassembly maintenance

Another solution is to install a heat-insulating sleeve, a reflective sleeve, and an electric heater fixing seat in the housing. The electric heater is fixed on the heat-insulating sleeve, and an elastic device is provided at the bottom of the reflective sleeve. It can float up and down in the heat insulation sleeve, and a radiation heating cavity is formed between the inner pot and the reflection sleeve. This structure solves the electrical safety problem of the electric heater, but the structure of the electric heater seat is relatively complicated, and the implementation cost is high, and the electric heater It is exposed, and the user can directly contact the high-temperature electric heater without putting it into the pot for heating, which has certain potential safety hazards. At the same time, debris is easy to fall into the electric heater, which is not easy to clean, such as Chinese patent CN2882482Y
