Method and device for detecting the influence of indoor odor in storage room of refrigerator on sense of smell, and refrigerator

Abstract

The invention provides a refrigerator and a method and device for detecting influence of odor in refrigerator storage chambers on smell. The method includes: detecting concentration of multiple gases or various kinds of gases having influence on smell of a user; determining gas influence value of the gas or that kind of gas at the concentration according to the concentration of each or each kind of the gases to obtain multiple gas influence values; according to preset weighting coefficients of the gases, calculating a weighted sum of the multiple influence values to obtain odor intensity used for representing influence degree of the odor in the storage chambers on smell. By using the method and device and the refrigerator, various gases with peculiar odor in the storage chambers can be combined to acquire a visual numerical value, namely the odor intensity used for representing influence degree of the odor in the storage chambers on smell, and peculiar odor condition in the storage chambers and the influence degree of the odor in the storage chambers on smell of human body can be directly judged according to the odor intensity.

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
