Refrigerator with function of detecting food smells and detecting method thereof

Abstract

The invention discloses a refrigerator with a function of detecting food smells. A smell detecting device, a peculiar smell eliminating device and an operational display device are arranged in the refrigerator, wherein the peculiar smell eliminating device is connected with a micro control unit (MCU) of the refrigerator. The smell detecting device comprises a control unit, a smell recognition unit and a smell collecting unit, wherein the control unit is connected with the MCU of the refrigerator, the smell recognition unit is connected with the control unit, and the smell collecting unit is connected with the smell recognition unit. The operational display device comprises a storage unit, an input unit, an output unit and a food managing unit, wherein the storage unit is connected with the MCU of the refrigerator, and the storage unit is connected with the input unit, the output unit and the food managing unit. According to the refrigerator with the function of detecting the food smells, changes of food volatilized gas compositions are detected, and a detecting method of distinguishing food fresh degrees is provided for consumers accurately. Deteriorated food is prevented from being eaten by mistakes, meanwhile, waste can also be completely eradicated.

Description

Technical field: [0001] The invention relates to a refrigerator with food odor detection function and a detection method thereof, belonging to the field of intelligent refrigerators. Background technique: [0002] With the improvement of living standards, more and more food is "hoarded" in household refrigerators. If the food is not stored properly during the shelf life, it will "expire early". Different characteristic gases will be volatilized at different stages in the food storage process. By detecting the characteristic gas components, it can be judged whether the food has deteriorated, thereby helping consumers to judge the freshness of the food more accurately. [0003] At present, smart refrigerators have been launched in the refrigerator industry one after another. These smart refrigerators mainly judge whether food has deteriorated according to the preset food preservation period, but cannot reflect the freshness of food in real time and accurately. Invention cont...
