Method for automatically regulating and controlling temperature and humidity of storage cabinet

Abstract

The invention discloses a method for automatically regulating and controlling temperature and humidity of a storage cabinet. The method comprises the following steps that after a microprocessor receives temperature and humidity signals and when the temperature is lower than a set value, the microprocessor controls a heating sheet to perform heating; when the temperature is higher than the set value, the microprocessor controls a compressor to start to begin to perform refrigerating to enable the interior of a storage cabinet body to be rapidly cooled; when the humidity is higher than a presetnumerical value, the microprocessor controls a circulation fan to operate and blow air for dehumidifying from a position close to a top plate to the lower portion; when the humidity is lower than thepreset numerical value, the microprocessor controls an evaporator to evaporate water inside the evaporator into water vapor through microwaves and release the water vapor into the storage cabinet body, and the humidity inside the storage cabinet body is improved by combining the circulation fan. According to the method, the microprocessor is utilized to automatically control all the internal components to rapidly regulate and control the temperature and humidity, so that the storage environment of articles is stable and reliable, the situation that medicine loses efficacy or yogurt exceeds thetime limit does not need to be worried, the internal temperature difference can be controlled to fluctuate within a small range, and the interior can be kept to have enough humidity so as to meet thestorage requirements of vegetables.

Description

technical field [0001] The invention relates to a regulating method, in particular to a method for automatically regulating the humidity of a temperature storage cabinet, which belongs to the field of electric control. Background technique [0002] Storage cabinets are mainly used for the storage of medicines, food, fresh vegetables, etc. According to the storage requirements of different products, the temperature needs to be kept within a certain range. However, the existing storage cabinets use conventional simple controllers, which mainly rely on the temperature detected by the sensor, and then control the heater to change the temperature, and the temperature difference is relatively large; in addition, this controller cannot control The internal air humidity makes vegetables easy to dehydrate when stored for a long time. Contents of the invention [0003] In view of the problems existing in the above-mentioned prior art, the object of the present invention is to provi...
