Refrigerator and control method thereof

Abstract

The invention provides a refrigerator and a control method thereof. The control method of the refrigerator comprises the following steps of after acquiring a door closing signal of the refrigerator, starting a capacity detection device in a refrigerator storage compartment to detect the capacity available of the storage compartment; comparing the detected capacity available and the capacity available before a refrigerator door is closed; if the detected capacity available is larger than the capacity available before the door is closed, driving a cold source of the storage compartment to operate with large power, so that the refrigerator enters into a rapid cooling mode. According to the scheme of the invention, a detection assembly is arranged in the storage compartment, the used capacity of the storage compartment of the refrigerator is detected by utilizing an optical principle, the detection result is accurate, a door body of the refrigerator does not need to be opened, the usage experience of a user is improved, and the favorable storage environment is kept for food.

Description

technical field [0001] The invention relates to the field of refrigerator control, in particular to a refrigerator and a control method thereof. Background technique [0002] The intelligence of refrigerators is a direction of refrigerator development, and it is also the focus of research and development of many refrigerator manufacturers. With the improvement of living standards, people's requirements for refrigerators are not only limited to the basic food storage and preservation functions, but also have higher and higher requirements for intelligent operations that can facilitate people's lives and improve the quality of life. [0003] As a household appliance for storing food, users need to know the usage of the internal space of the refrigerator to determine the storage capacity of the food. In the prior art, people usually estimate the usable volume of the refrigerator by opening the refrigerator door to observe. This requires the user to operate near the refrigerato...

AI Technical Summary

Problems solved by technology

This requires the user to operate near the refrigerator, and frequent opening and closing of the refrigerator door will adversely affect the storage of food, which brings great inconvenience to the user.

[0004] In addition, after putting food at normal temperature in the refrigerator, the temperature of the refrigerator inside the storage compartment will rise. The traditional control method is generally to control the temperature. When the temperature is higher than the preset temperature, the cold source is turned on to cool the refrigerator. Refrigeration, turn off the cold source after reaching the preset temperature

However, this method generally cannot solve the impact of new food on existing food, resulting in a decline in the preservation effect
