A method for identifying ambient temperature using a temperature sensor in a refrigerator, and the refrigerator

Abstract

The invention discloses a refrigerator using a temperature sensor to identify the ambient temperature and the refrigerator, relates to the technical field of refrigerator control methods, and is designed to solve problems such as inaccurate identification of the ambient temperature of the existing refrigerator. The refrigerator uses a temperature sensor to identify the ambient temperature. The controller of the refrigerator pre-stores the pre-stored sampling data S' and the pre-stored ambient temperature corresponding to the pre-stored sampling data S', and the controller samples the evaporator temperature sensor to obtain the current temperature. Sampling data S, and comparing the current sampling data S with the pre-stored sampling data S' to obtain the current ambient temperature. At the same time, a refrigerator using the above method is proposed. The method for using a temperature sensor in a refrigerator to identify the ambient temperature provided by the present invention can obtain the current ambient temperature without separately installing a temperature sensor with a negative temperature coefficient on the display panel of the refrigerator. The obtaining method is simple and the obtained ambient temperature is accurate.

Description

technical field [0001] The invention relates to the technical field of refrigerator control methods, in particular to a method for identifying ambient temperature using a temperature sensor in a refrigerator and a refrigerator for realizing the method. Background technique [0002] As the energy consumption of refrigerators continues to upgrade, more and more refrigerators start to use inverter compressors. When controlling the speed of inverter compressors, the ambient temperature around the refrigerators needs to be used as a control parameter. At the same time, in order to control the consistency between the refrigerating room or variable room and the set gear under different ambient temperatures, it is necessary to use different control parameters to adjust the start and stop points of the refrigerating room or variable room under different ambient temperatures to achieve control. The purpose of cold room or variable room temperature. [0003] At present, the method of ...

AI Technical Summary

Problems solved by technology

[0003] At present, the method of obtaining the ambient temperature is generally to install a temperature sensor with a negative temperature coefficient on the display panel of the refrigerator, and use this temperature sensor to sense the ambient temperature around the refrigerator. The ambient temperature obtained in this way is not accurate enough and requires an additional temperature sensor , increasing the cost of the refrigerator
