Heat storage type electric heater

Abstract

The invention discloses a heat storage type electric heater, and belongs to the field of heating equipment. By installing a hollow cavity and a heat storage layer, the heat storage and the heating ofsurrounding gas are synchronously carried out, and the heating rate when the heater is just started is effectively improved; and meanwhile, in the using process, by arranging an inner heat conductionnet, the local overheating phenomenon caused by caking can be effectively avoided under the condition that the surface of an electric heating tube does not need rough treatment, and under the action of the hollow cavity, a lower-layer heat storage and an expansion gap, the volume increase of the heat storage layer caused by thermal expansion of the heat storage layer can be compensated at the sametime from the upper portion, the lower portion and the inner portion, the safety hazard caused by excessive expansion of the heat storage layer is effectively avoided, and the safety of the heater isobviously improved.

Description

technical field [0001] The invention relates to the field of heating equipment, more specifically, to a heat storage type electric heater. Background technique [0002] With the continuous development of society, people's quality of life is gradually improving, and the way people keep out the cold is also constantly improving, from drilling wood for heating to raising furnaces for heating, and then to today's electric heaters and air conditioners, etc. Heating equipment and electric heaters can be widely used in residential, office, hotel, shopping malls, hospitals, schools, train carriages and other mobile heating, simple activity rooms and other civil and public buildings. Integrating radiation and convection, the interior is made of high-efficiency aluminum alloy cooling fins, with strong radiation ability and large radiation area. It uses electrothermal film as the heating material. Its super-large black crystal mirror surface is stylish and fully meets the needs of peop...

AI Technical Summary

Problems solved by technology

[0004] The electric heaters in the prior art generate heat through the heating components after being energized, thereby heating the surrounding air. Once a power outage occurs, the temperature of the surrounding air will drop rapidly, making it difficult to meet the needs of users. However, heat storage electric heaters Due to the existence of heat storage, when it is just turned on, its temperature rise rate for the room is very slow. After the expansion, the volume is large and the phenomenon of damage to the electric heater is caused. In severe cases, it may even explode, which poses a great safety hazard.
