Description

technical field [0001] The invention relates to the field of controllers, in particular to a timing and constant temperature controller. Background technique [0002] The development of temperature controllers has roughly gone through three stages: mechanical, electronic and intelligent. Most of the early mechanical temperature controllers were made using the principle of thermal expansion and cold contraction of bimetallic strips, and its typical representative is the bimetallic strip thermostat. The mechanical temperature controller has the advantages of low price and simple structure; but its temperature drift is large, the control error is large, and the control accuracy is low, which is difficult to meet the needs of social development. With the development of electronic technology, an electronic temperature controller has appeared on the basis of a mechanical temperature controller. It uses a sampling circuit for temperature detection, controls the output through a lo...

Problems solved by technology

[0005] 1. Can not well meet the demand for energy saving;

[0006] 2. Most of the existing temperature controllers are based on the 220 / 120 volt system, and applying it in the family will cause a certain degree of safety hazard

[0007] 3. The existing temperature controllers can adjust fewer parameters, and cannot make the most appropriate adjustments to the fundamental object "people" they serve, resulting in differences between the adjusted temperature and the real temperature required by people
