Abstract

The invention provides a food spoilage detection method and a refrigerator, is used for solving technical problems that a refrigerator in the prior art cannot detect and judge whether food stored in the refrigerator goes bad, and achieves technical effects of refrigerator self intelligent detection and judgment of spoilage of the stored food. The method comprises the steps: acquiring at least one frame of image of at least one food in a holding space by K image acquisition units; detecting the concentration of at least one gas substance in the food holding space by N sensors, and thus obtaining a first concentration value; judging whether the first concentration value exceeds a threshold value, and thus obtaining a first judgment result; and when the first judgment result indicates that the first concentration value exceeds the threshold value, judging that at least one food in the food holding space goes bad based on at least one frame of image.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for detecting food deterioration and a refrigerator. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also an electronic device that keeps food or other items in a constant low temperature and cold state. Since the advent of the refrigerator in the 1920s, it has enabled people to preserve food for a longer period of time, and has greatly promoted the quality of human life. [0003] Today, almost every household buys a refrigerator to preserve food such as fruits, meat, vegetables, and snacks. However, storing food in the refrigerator just to provide a constant low temperature environment for food does not mean that the food will not deteriorate and expire. However, refrigerators in the present technology only have a storage function, and judging whether food is expired requires the user to j...
