Abstract

The invention provides a refrigerator and a temperature measuring method based on infrared sensors. The temperature measuring method based on the infrared sensors includes the steps that the infrared sensors are used for sensing the temperatures in preset regions; the sensing results of the infrared sensors are collected every other preset time, and temperature sampling values are acquired; a continuous preset number of temperature sampling values are acquired, and the maximal sampling value and the minimal sampling value are screened out from the acquired temperature sampling values; the average values of the temperature sampling values in which the maximal sampling value and the minimal sampling value are screened out are calculated, and the average values serve as the temperature measured values of the infrared sensors. By the adoption of the scheme, the influences on measuring accuracy from measured value fluctuation of the infrared sensors can be avoided, temperature measuring accuracy is improved, the measured values can directly reflect actual temperatures of objects in the preset regions, and the accurate control basis is provided for following related control.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a refrigerator and a temperature measurement method based on an infrared sensor. Background technique [0002] Existing refrigerators usually use a temperature sensor arranged inside a compartment to sense the temperature around the location where it is arranged, and use the temperature as a basis for refrigeration control. [0003] However, when using this control method to control the refrigerator, when the temperature measured by the temperature sensor is higher than the preset value, the refrigerator starts cooling. However, when the temperature sensor measures the temperature, the measured value may fluctuate, which may deviate from the actual temperature inside the storage compartment, resulting in poor accuracy of the measured temperature. Using this temperature measurement for cooling control results in less efficient storage. [0004] In addition, during the actual use of the...
