Description
Technical field
The invention belongs to refrigerator arts, more particularly to a kind of refrigerator and its method of detection food freshness.
Background technology
Food is in harvesting, transport, storage, if method is improper easily to cause corruption, in order to reduce food because of corruption
Caused by lose, and cause because of food spoilage to generate offensive gases in refrigerator, need to detect food freshness and right in time
People remind.Food detection method generally has organoleptic detection and physical and chemical index detection, is applied to the food freshness of refrigerator
Detection method is typically nondestructive determination.
Existing many people enough buy many food and put refrigerator into and store for convenience, as a result because how eastern setier is in refrigerator
West, until we find out desired food, it is rotten or expired, leads to the waste of food.Therefore, with people
Consumption upgrading, refrigerator is increasing, and desirable functional requirement is also more and more, and large refrigerator classification storage is also that consumption becomes
Gesture, especially function prefecture refrigerator are more and more favored by consumers, and general function refrigerator can no longer meet present consumption
The life requirement of person.
Invention content
The purpose of the present invention is to provide a kind of refrigerators and its method of detection food freshness, by operation display area and
Store detection zone, solve current refrigerator shortage food freshness is detected and is reminded in real time, caused by food
It rots and has unpleasant gas problem in refrigerator.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions：
