Refrigerator

Abstract

The invention provides a refrigerator. The refrigerator comprises a refrigerator body, a plurality of detection assemblies and a volume calculation device. A storage compartment is defined in the refrigerator body, the refrigerator body comprises a top wall, a bottom wall and vertically-arranged side walls, and the top wall and the bottom wall are arranged horizontally. The detection assemblies are selectively arranged on one or more of the top wall, the bottom wall and the side walls, and each detection assembly at least comprises a light-sensitive apparatus; the light-sensitive apparatuses are configured to detect the visible light intensity and the infrared intensity of the positions where the detection assemblies are located; and the volume calculation device is connected with the multiple detection assemblies, is configured to obtain the visible light intensity and the infrared intensity and calculates the using volume of the refrigerator compartment according to the visible light intensity and the infrared intensity. According to the refrigerator, the optical principle can be utilized for detecting the utilized volume of the storage compartment of the refrigerator; and the detection result is precise, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the field of refrigerator control, in particular to a refrigerator. 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 refrigerator, and frequent opening and c...

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] Based on the above problems, in the prior art, there are also various technical means using weight sensors to measure the weight of objects in the refrigerator, detecting the storage status of specific storage locations, and arranging cameras to obtain the usage of the refrigerator space. However, some of these solutions detect The results are inaccurate, some can only detect special foods, and cannot accurately reflect the actual use of the refrigerator volume
