Controller, method for controlling heater body and electric heater

Abstract

The invention provides a controller, a method for controlling a heater body and an electric heater. The controller is applied to the electric heater and comprises a temperature regulation module, a main control chip and a switch tube, wherein the temperature regulation module is configured to receive target temperature input by a user, detect environment temperature of an area in which the heater body is located, calculate the temperature difference of the target temperature and the environment temperature and send the temperature difference to the main control chip; the main control chip is configured to calculate a target duty ratio according to the temperature difference when the received temperature difference is less than a set temperature value and send a pulse signal to the switch tube according to the target duty ratio; the switch tube is configured to be communicated and disconnected periodically according to the received the pulse signal, so that an external AC (alternating current) power module is enabled to periodically supply working voltage to the switch tube. According to the technical scheme of the invention, the change rate of the environment temperature of the area, in which the heater body is located, is relatively low, and the comfort level of human bodies is improved, so that the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a controller, a method for controlling a heater body, and an electric heater. Background technique [0002] With the development of technology and the improvement of people's living standards, the application of electric heaters has been widely popularized. [0003] At present, electric heaters usually include a controller and a heater body. The external AC power supply can provide a working voltage to the heater body through the controller, and the heater body can be controlled at rated power according to the working voltage continuously provided by the AC power supply through the controller. When the controller detects that the ambient temperature in the area where the heater body is located reaches the target temperature input by the user, it disconnects the connection between the external AC power supply and the heater body, so that the heater body stops heatin...

AI Technical Summary

Problems solved by technology

[0004] In the above technical solution, the heater body of the electric heater can only operate at the rated power. When the difference between the ambient temperature and the target temperature input by the user is small, the rate of change of the ambient temperature in the area where the heater body is located is relatively fast, which may cause human body comfort. Reduced speed and poor user experience
