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

Embodiment 1

[0029] This embodiment is a method for using a temperature sensor in a refrigerator to identify the ambient temperature. The evaporator temperature sensors described below are all evaporator temperature sensors in the refrigerator.

[0030] Firstly, it is necessary to obtain the pre-stored sampling data S' and the pre-stored ambient temperature corresponding to the pre-stored sampling data S'. Since the ambient temperature of the refrigerator is changing, it is necessary to obtain pre-stored sampling data S' under multiple pre-stored ambient temperatures. The acquisition method of the pre-stored sampling data S' at each pre-stored ambient temperature is the same. The following only introduces a method for obtaining pre-stored sampling data S' at a pre-stored ambient temperature.

[0031] The conversion of analog signal to digital signal is called digital-to-analog conversion, referred to as AD conversion. The temperature of the evaporator temperature sensor is sampled throug...

Abstract

The invention discloses a refrigerator and an environment temperature recognition method for a temperature sensor for the refrigerator, and relates to the technical field of refrigerator control methods. The environment temperature recognition method solves the problem that existing refrigerator environment temperature recognition is inaccurate. The environment temperature recognition method for the temperature sensor for the refrigerator comprises the steps that prestored sampling data S' and prestored environment temperature corresponding to the prestored sampling data S' are prestored inside a controller of the refrigerator, the controller samples the evaporator temperature sensor to obtain current sampling data S, and the current environment temperature is obtained by comparing the current sampling data S with the prestored sampling data S'. The invention further provides the refrigerator adopting the environment temperature recognition method. According to the environment temperature recognition method for the temperature sensor for the refrigerator, the current environment temperature can be obtained without the requirement for independently arranging a temperature sensor with negative temperature coefficients on a display panel of the refrigerator, the obtaining mode is easy and convenient, and the obtained environment 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 ...
