Abstract

The invention discloses a refrigerator and a control method thereof. The refrigerator comprises a refrigerating box, an infrared detection device arranged at the inner side of a refrigerating door, independently controlled air outlet doors arranged in all interlayers in the refrigerating box, and a controller for controlling the infrared detection device to work according to the opening and closing state of the refrigerating door and set time. The controller controls the air outlet doors of the corresponding interlayers to be opened or closed according to the temperature of the food in each interlayer. According to the refrigerator, the infrared detection device is adopted to replace a plurality of traditional temperature sensors to detect the temperature of a refrigerator compartment. An infrared sensor is used for scanning the food in each interlayer of the refrigerating box, the real-time temperature of the food is obtained, and air supply refrigeration is independently controlled according to needs. Therefore, the refrigerator can accurately measure the temperature of the food and can reasonably and accurately control the temperature.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a refrigerator capable of accurately detecting the temperature of food in a compartment and controlling the temperature reasonably and precisely, and a control method thereof. Background technique [0002] The development of today's home appliance industry is changing with each passing day, and people's lives are becoming more and more intelligent. For the detection of temperature in the traditional refrigerator compartment, a single temperature sensor is installed in the refrigerator compartment, and the real-time temperature of the refrigerator compartment is measured by the temperature sensor to control the start and stop of the compressor to determine whether it is cooling. Because the temperature in the compartment of the refrigerator is not uniform, a single temperature sensor often cannot accurately measure the temperature in the compartment. In order to solve this problem, for ...
