Method and device for detecting influence of indoor smells of refrigerator storage room on olfactory sense and refrigerator

Abstract

The invention provides a method and device for detecting the influence of indoor smells of a refrigerator storage room on the olfactory sense and a refrigerator. The method for detecting the influence comprises the steps that the concentrations of multiple or multiple kinds of gas, influencing the olfactory sense of a user, in the storage room are detected, and a plurality of concentration values are obtained; the weighted sum of the concentration values is calculated according to the preset weight coefficient of each or each kind of gas, and the smell strength used for representing the influence degree of the indoor smells of the storage room on the olfactory sense is obtained. According to the method and device for detecting the influence of the indoor smells of the refrigerator storage room on the olfactory sense and the refrigerator, a visual numerical value, namely, the smell strength used for representing the influence degree of the indoor gas of the storage room on the olfactory sense can be obtained by synthesizing the indoor smell gas of the storage room, and the peculiar smell condition in the storage room and the influence degree of the indoor smells of the storage room on the olfactory sense of the human body can be directly judged according to the smell strength.

Description

technical field [0001] The invention relates to the technical field of refrigerator storage, in particular to a detection method and device for detecting the influence of indoor odor in a refrigerator storage room on the sense of smell, and a refrigerator. Background technique [0002] Refrigerator is a kind of refrigeration equipment that keeps a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. With the development of society, people are increasingly inseparable from refrigerators. However, sometimes when users open the refrigerator, they will smell a strange smell, which smells disgusting. The main reasons for these peculiar smells may be as follows: 1) Because some food in the refrigerator has been stored for a long time or some food residues will emit peculiar smell, this smell will adhere to the inner container of the refrigerator or the shelf and fruit box; 2) Some foods are mixed,...

However, sometimes when users open the refrigerator, they will smell a strange smell, which smells disgusting

The main reasons for these peculiar smells may be as follows: 1) Because some food in the refrigerator has been stored for a long time or some food residues will emit peculiar smell, this smell will adhere to the inner container of the refrigerator or the shelf and fruit box; 2) Some foods are mixed, especially some foods that are prone to odors are not packaged, and they are prone to odors after being stored for a period of time; 3) Some foods will be attached to the inner liner during the use of the refrigerator. If the refrigerator is stopped but not cleaned Or if the door is not opened, peculiar smell will be produced after a long time; 4) Since the food in the refrigerator has deteriorated and the user cannot know, the peculiar smell will be strung into the stored food during use, resulting in the phenomenon of cross-smelling

Moreover, the current odor sensors on the market generally can only identify and detect one gas, and cannot accurately reflect the odor in the refrigerator, and their lifespan is relatively short, so they cannot be well detected on the refrigerator. application, and because the gas composition inside the refrigerator is generally complex, it is difficult to identify all odors with one sensor
