Refrigerator and method of temperature measurement based on infrared sensor

Abstract

Provided are a refrigerator, and a method for temperature measurement based on an infrared sensor (130). The method for temperature measurement based on an infrared sensor (130) comprises: using an infrared sensor (130) to sense the temperature inside a preset zone; acquiring at predetermined time intervals the sensed result of the infrared sensor (130) to obtain sample temperature values; obtaining a continuous predetermined quantity of sample temperature values and filtering the maximum sample value and the minimum sample value out of the obtained sample temperature values; calculating the average value of sample temperature values after having filtered out the maximum sample value and the minimum sample value, and taking the average value to be the measured temperature value of the infrared sensor (130). Using the solution of the present invention, it is possible to prevent fluctuations in the values measured by the infrared sensor from affecting measurement accuracy; thus the accuracy of temperature measurement is improved, such that measured values directly reflect the actual temperature of the items inside a preset zone, and an accurate basis for control is provided for subsequent associated 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...
