Refrigerator and refrigerator use volume detection method

Abstract

The invention provides a refrigerator and a refrigerator use volume detection method. The refrigerator comprises a lighting light source, at least one detection component and a volume calculation unit. The lighting light source is arranged in a storage room of the refrigerator and is configured to provide visible light for the storage room. The at least one detection component is arranged in the storage room. Each detection component at least comprises an infrared source and a light sensing unit. The infrared sources are configured to send infrared light to the inside of the storage room, and the light sensing units are configured to detect the visible light intensity and the infrared intensity of positions of the detection components. The volume calculation unit is connected with the light sensing units of the at least one detection component and is configured to obtain the visible light intensity and the infrared intensity and calculate the use volume of the storage room according to the visible light intensity and the infrared intensity. By means of the technical scheme, the detection components are arranged in the storage room, the refrigerator storage room used volume is detected through an optical principle, detection results are accurate, and the user use experience is improved.

Description

technical field [0001] The invention relates to the field of refrigerator control, in particular to a refrigerator and a method for detecting the use volume of the 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 food. In the prior art, people usually estimate the usable volume of the refrigerator by opening the refrigerator door and observing the compartments. This ...

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
