Refrigerator and its temperature control device and temperature control method

Abstract

The invention discloses a refrigerator-temperature control method and control device. The refrigerator-temperature control method comprises the following steps of when a door of a refrigerator is opened, acquiring temperature T1-TN detected by temperature sensors; when the door of the refrigerator is closed, acquiring temperature T1'-TN' detected by the temperature sensors after the door of the refrigerator is closed for preset time; judging whether the refrigerator is controlled to enter a preset working mode according to the temperature T1-TN and the temperature T1'-TN'; and if the refrigerator enters the preset working mode, correspondingly increasing the rotating speed of a compressor and / or a fan. The refrigerator-temperature control method and control device disclosed by the invention have the advantages that N temperature sensors are arranged in the refrigerator, so that the expanding range of the temperature detected by the temperature sensors is realized, the indoor temperature is accurately controlled, the temperature change of separated rooms is fast sensed, the phenomenon of local supercooling is prevented, the stopping points of the separated rooms are reduced, the refrigerating time is shortened and the needs of a user are better met. The invention also discloses the refrigerator.

Description

technical field [0001] The invention relates to the technical field of living appliances, in particular to a refrigerator temperature control method, a temperature control device and a refrigerator with the temperature control device. Background technique [0002] At present, in the prior art, usually only one temperature sensor is installed in each compartment of the refrigerator to detect the temperature signal, and loads such as compressors, fans, dampers, etc. are controlled according to the temperature signal detected by the temperature sensor, so as to realize the control of each compartment. temperature. [0003] The disadvantage of the prior art is that since only one temperature sensor collects temperature signals, the range of sensing temperature is relatively limited, resulting in inaccurate temperature control. For example, when the distance between the food and the temperature sensor is long, the food has little influence on the detection value of the temperatu...

AI Technical Summary

Problems solved by technology

[0003] The disadvantage of the existing technology is that since only one temperature sensor collects the temperature signal, the range of sensing temperature is relatively limited, resulting in inaccurate temperature control

For example, when the distance between the food and the temperature sensor is long, the food has little influence on the detection value of the temperature sensor. Set the temperature, so the control refrigeration device stops cooling, resulting in insufficient cooling time

Conversely, if the food is very close to the temperature sensor, the food will have a greater impact on the detection value of the temperature sensor. Even if the food in other parts of the refrigerator has reached the preset temperature, the food near the temperature sensor still has not reached the preset temperature, resulting in refrigeration. The device is still cooling, resulting in overcooling of other parts, which cannot meet the needs of users well
