Temperature control method and device for a refrigerator, and refrigerator

Abstract

The embodiment of the invention discloses a temperature control method and device of a refrigerator and the refrigerator. The method comprises the following steps that the target temperature and the wave difference of a target chamber, and the temperature deviation amount and the additional deviation amount of the adjacent chambers are obtained; according to the target temperature, the wave difference, the temperature deviation amount and the additional deviation amount, the starting temperature and the shutdown temperature of the target chamber are calculated; and if it is judged that the target chamber reaches the starting temperature, the temperature control of the target chamber is started, and if it is judged that the target chamber reaches the shutdown temperature, the temperature control of the target chamber is closed. Through calculating the starting temperature and the shutdown temperature of the target chamber, the starting and closing of the temperature control in the target chamber is controlled according to the starting temperature and the shutdown temperature, the temperature control points of the chambers can be dynamically balanced, no extra heat preservation refrigerator is needed, more volume and cost can be saved, and meanwhile, the problem that the local temperature in each chamber is not controlled can be avoided, so that various temperature control requirements of a user on the chambers of the refrigerator are met.

Description

technical field [0001] The invention relates to the technical field of refrigeration control, in particular to a refrigerator temperature control method and device, and the refrigerator. Background technique [0002] With the improvement of living standards, the functions of refrigerators are becoming more and more complex. As a household appliance for storing food in partitions, independent compartments with various temperature ranges have been developed for storing various ingredients. Because the target temperature of each room is different, if the insulation is not good, it will affect each other during work. For example, when the normal temperature compartment maintains a higher temperature, it may cause the local temperature of the surrounding low temperature compartment to be higher. When the low-temperature compartment is refrigerated, the temperature of the part in contact with the normal-temperature compartment will also be low. [0003] In order to solve this p...

AI Technical Summary

Problems solved by technology

However, strengthening the insulation will increase the cost and the processing technology will be more complicated; the use of insulation materials will lose the effective volume of the refrigerator; at the same time, insulation is relative, and the existing technology cannot prevent the local temperature from being uncontrolled The degree of control cannot meet the needs of users
