Low temperature compensating device based on external environment temperature of refrigerator, and single low temperature compensation refrigerator

Abstract

The invention relates to a low temperature compensating device based on external environment temperature of a refrigerator, and a single low temperature compensation refrigerator. The low temperature compensating device comprises a temperature sensing probe, a heating element and a microprocessor, wherein the microprocessor is used for controlling start of the heating element according to the external environment temperature, detected by the temperature sensing probe, of the refrigerator; the heating element starts to heat a refrigerating chamber so as to increase the start times of a refrigeration system and prolong the total running time, so that the temperature of a freezing chamber can be reduced. The refrigerator comprises the refrigerating chamber and the freezing chamber, wherein the refrigerating chamber and the freezing chamber are capable of realizing refrigeration simultaneously during work of the refrigeration system; the longer the running time of the refrigeration system is, the better the temperature reduction effect of the freezing chamber is; the heating element arranged inside the refrigerating chamber can be intelligently started according to the external environment temperature of the refrigerator, so that the running time of the refrigeration system can be prolonged and the start times of the refrigeration system can be increased, and thus the temperature of the freezing chamber can be lowered to satisfy the temperature requirements of the freezing chamber.

Description

technical field [0001] The invention relates to the technical field of refrigerator refrigeration, in particular to a low temperature compensation device based on the external ambient temperature of the refrigerator and a single low temperature compensation refrigerator. Background technique [0002] With the improvement of people's living standards, refrigerators have become one of the necessary household appliances for every family. Current refrigerators can be classified into mechanical temperature control and electronic temperature control according to different temperature control methods. However, with the rapid development of electronic technology, the market coverage of mechanical temperature-controlled refrigerators is getting lower and lower, while the output of electronic temperature-controlled refrigerators is increasing. As far as electronic temperature-controlled refrigerators are concerned, they mainly include three types: single temperature control, double t...

Problems solved by technology

However, for the first method above, it is necessary to manually judge whether the ambient temperature is too low, and then turn on the low-temperature compensation element. This method is not smart enough, and if you forget to turn off the low-temperature compensation element after turning it on, it will greatly increase the energy consumption of the refrigerator.

For the above second approach, although it is sufficiently intelligent, it is necessary to add a solenoid valve to the system, and the cost of the entire product will be greatly increased
