Abstract

The invention discloses a heat storage type electric heater which comprises a shell. A heat storage cavity is formed in the shell; and an electric heating unit is arranged in the heat storage cavity, and a heating air opening used for the electric heating unit to release hot air is formed in the side wall of the heat storage cavity. The electric heating unit is connected with a power supply unit through a wire in an electric control mode, and the power supply unit is used for supplying power to the electric heating unit; the power supply unit is connected with an external control machine through a WIFI signal connection mode in an electric control mode; and an electromagnetic heating unit is arranged above the heat storage cavity. Compared with a traditional heat storage type electric heater, a heating wire of an electric heating tube of the electric heater is made of a nichrome material and filled with 98% of high-purity high-temperature electrical-grade magnesium oxide powder, so that a higher heat transfer rate can be achieved, and better heat release efficiency is achieved; and a heat storage structure of magnesium-iron bricks is added, certain heat can be effectively stored in the period of low-price electric energy, and therefore the stored heat is released in the period of high-price electric energy, and it is guaranteed that the indoor temperature is stable in the heating period.

Description

technical field [0001] The invention relates to the technical field of electric heaters, in particular to a thermal storage electric heater. Background technique [0002] Regenerative electric heaters use the low-priced (only 3 cents per kilowatt-hour in Beijing) electric energy during the night (23:00 to 7:00 the next day) of the power grid to complete the conversion of electricity and heat within 6-8 hours. Storage, during the peak hours of the power grid, the stored heat is released in the form of radiation and convection to achieve indoor heating 24 hours a day. [0003] Existing thermal storage electric heaters have a single structure, and only use common electric heating tubes to release hot air. It will be released, resulting in insufficient heat during the heating period, and the single heating effect can not be recovered and utilized by other heat releasing equipment in the room, wasting a lot of power resources. Contents of the invention [0004] The object of ...
