Technical Field

The invention relates to the technical field of refrigerators, in particular to a simple computer temperature control refrigerator.

Background

The traditional mechanical temperature control refrigerator adopts a mechanical temperature controller to control and adjust the temperature of the refrigerator, and the control principle is as follows: the mechanical temperature controller mainly comprises a temperature sensor, a group of micro switches and other mechanisms, the temperature change in the evaporator or the tank is sensed by the temperature sensing agent in the temperature sensing cavity and converted into pressure change, and the contact is pushed to act so as to control the start and stop of the compressor. Due to the structural characteristics of the temperature control device, the temperature control device can be effectively controlled only by a large temperature difference, so that the temperature control effect is poor; meanwhile, the defects of temperature drift, large error, no shutdown, no startup and the like exist, which leads to a large amount of customer complaints and after-sale maintenance. Meanwhile, the mechanical temperature control refrigerator cannot realize a quick-freezing mode of automatic exit. Moreover, although computer temperature control refrigerators are available in the market, the functions are rich, but the price is several times or even tens of times higher than that of mechanical temperature control refrigerators.
