Method and device for detecting capacity available of refrigerator

Abstract

The invention provides a method and a device for detecting the capacity available of a refrigerator. The method for detecting the capacity available of the refrigerator comprises the following steps of utilizing a plurality of detection assemblies arranged in a storage compartment of the refrigerator to respectively detect visible light intensity and infrared light intensity of respective positions, wherein the storage compartment is divided into a plurality of storage spaces, and each detection assembly is arranger in one storage space; confirming one detection target storage space from the plurality of storage spaces; utilizing visible light intensity detected by the detection assembly in the detection target storage space and visible light intensity and infrared light intensity detected by the detection assembly adjacent to the detection assembly in the detection target storage space in the vertical direction to calculate the used capacity of the detection target storage space. With the scheme provided by the invention, the detection of the capacity available is realized according to the difference between the projection and the reflection of the visible light and the infrared light and the influence of the size of the capacity available on the light intensity, the detection result is accurate, and the use convenience of users is improved.

Description

technical field [0001] The invention relates to the field of refrigerator control, in particular to a method and device for detecting the use volume of 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 opera...

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
