Heating control system of electric heater

Abstract

The invention discloses a heating control system of an electric heater, comprising a control unit and a heating part, wherein the control unit is used for controlling the heating part; the heating part comprises a first heating unit and a second heating unit. When the control unit receives a third signal from a switch unit, a timing unit is started to begin timing, and one of the first heating unit and the second heating unit is started; when the time counted by the timing unit reaches the preset time, the timing unit sends a switching signal to the control unit, and the timing unit is cleared and the time is counted again; when the control unit receives the switching signal from the timing unit, the control unit makes one, which is opened, of the first heating unit and the second heating unit closed, and makes one, which is closed, of the first heating unit and the second heating unit opened, so that the opening and the closing of the first heating unit and the second heating unit are switched.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, the invention relates to a heating control system for an electric heater. Background technique [0002] Electric heater equipment can be widely used in residential, office, hotel, shopping malls, hospitals, schools, train carriages and other mobile heating, simple activity room and other civil and public buildings. [0003] There are five main types of common electric heaters on the market: reflective far-infrared electric heaters, air heaters, oil heaters, European-style fast heating furnaces and European-style electric heaters. [0004] Electric heaters are widely used in areas without heating, or in a period of time before heating is provided although there is heating. [0005] Now the intelligent temperature control function of electric heater equipment has been developed. The intelligent temperature control function consists of two parts, one is the temperature sen...

AI Technical Summary

Problems solved by technology

[0006] However, since the user generally uses the electric heater for a long time when using the electric heater, the heating unit of the electric heater will continue to work for a long time (for example, continue to work for more than ten hours)

However, if the heating unit continues to operate for a long time, the service life of the heating unit will be shortened, and the probability of burning out the heating unit and causing a fire will increase
