Refrigerator

Abstract

The invention provides a refrigerator, which comprises a refrigerator body and a detection assembly, wherein a storage compartment is limited in the refrigerator body; the capacity of the storage compartment is less than or equal to a preset threshold; the detection assembly is arranged in the storage compartment and at least comprises a light-sensitive apparatus and a capacity calculation device; the light-sensitive apparatus is configured to detect visible light intensity and infrared light intensity of the position where the detection assembly is located; the capacity calculation device is connected with the detection assembly and is configured to acquire the visible light intensity and the infrared light intensity, and calculate the capacity available of the storage compartment according to the visible light intensity and the infrared light intensity. According to the refrigerator provided by the invention, the detection assembly is arranged in the storage compartment with the capacity available being less than or equal to the preset threshold, 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. 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...

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] 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, and some can only detect special foods, which cannot accurately reflect the actual use of the refrigerator volume
