Control method of electric heater based on temperature value change control

Abstract

The invention relates to a control method of an electric heater based on a temperature value change control. The control method comprises the following steps of, acquiring a first temperature value, asecond temperature value, a third temperature value and a fourth temperature value; judging the change in the relation among the first temperature value, the second temperature value and the third temperature value, adjusting the working power of the electric heater according to the change, judging whether the changes of the first temperature value, the second temperature value and the third temperature value reach a preset range or not, and automatically adjusting a surrounding temperature value of the heating for temperature control if the preset range is not reached.

Description

technical field [0001] The invention belongs to the field of control methods, in particular to a control method for controlling electric heaters based on temperature value changes. Background technique [0002] Electric heaters can be widely used in residential buildings, offices, hotels, 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 heat dissipation fins, with strong radiation ability and large radiation area, and electric heating film is used as the heating material; it mainly sends heat by means of far-infrared radiation and heat convection.

AI Technical Summary

Problems solved by technology

[0003] The existing electric heater has a kind of humidification type electric heater, which performs humidification operation while heating, so that the heating environment is not so dry, but the existing electric heater has several deficiencies that need to be improved. 1. Due to the electric The range of heating is uneven, and it is impossible to guarantee that the temperature value of the outermost periphery meets the demand. Sometimes the temperature value that the user wants needs to be felt at the front, which is very inconvenient. 2. Due to the change of the surrounding temperature, every time you want to adjust the temperature Values ​​need to manually adjust the heating temperature value, and it is impossible to automatically adjust according to the change of the surrounding temperature. 3. After the temperature reaches the set temperature, the temperature change cannot be maintained, and the temperature change fluctuates greatly; Improvements are made to make up for the shortcomings of the deficiencies in this concentration
