Refrigerator and method for detecting its use volume

Abstract

The invention provides a refrigerator and a use capacity detecting method. The method comprises the following steps: previously dividing multiple use capacity levels according to the ratio value of the use capacity of the refrigerator to the total capacity of refrigerating and freezing chambers of the refrigerator; starting lighting devices arranged in the refrigerating and freezing chambers so asto provide visual light for the chambers of the refrigerator; starting a plurality of photosensitive modules so as to detect the visual light intensity of positions at which the photosensitive modules are located; and determining the use capacity level of the refrigerator according to the visual light intensity. The detecting method utilizes optical means to detect the size range of the use capacity of the refrigerator, can utilize the detected range to realize smart control over the refrigerator, improves the smart level of the refrigerator and improves the use experience of the users.

Description

technical field [0001] The invention relates to a refrigerating and freezing device, in particular to a refrigerator and a detection method for its use volume. 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 requires the user ...

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
