Background

Generally, vegetables, fruits and beverages are suitable to be stored at a temperature of about 4 ℃; the meat food must be stored at a low temperature of at least 18 ℃ below zero, and can be stored for half a year, and the meat cannot be stored for a long time at the temperature higher than-18 ℃; fresh meat can then be stored at a temperature of around 0 degrees for a short period of time. The refrigerator is required to have a three-door design, namely, the refrigerating temperatures of different spaces of the refrigerator are subdivided, so that the requirement of storing more kinds of food is met.

The existing three-door refrigerator is provided with three chambers from top to bottom, and the three chambers are respectively: a refrigerating chamber, a middle door chamber and a freezing chamber. According to the difference of refrigeration temperature, the middle door chamber can be divided into: constant temperature fresh-keeping layer, constant temperature soft layer, temperature limiting and adjusting layer and full temperature zone temperature adjusting layer.

Constant temperature fresh-keeping layer: the constant temperature design of about 0 degree (or small adjustment can be made within the temperature range of zero) is provided, and vegetable, fruit or fresh meat food can be stored for a long time.

Constant temperature soft freezing layer: the meat soft freezing chamber is a soft freezing chamber, the temperature is kept at minus 7 ℃, the meat can be stored in soft freezing, and the meat can be unfrozen and cut more easily after being taken out. However, in practice, meat is not preserved for as long as-18 degrees, so that the meat has a short preservation time and is not suitable for preserving food for a long time.

Temperature limiting and adjusting layer: the adjustable temperature is about 4 to-3 degrees (sometimes can reach a wide range of-7 to 10 degrees, but the temperature adjusting layer can only be limited when the temperature is below-18 degrees), and the intermediate layer usually has certain temperature adjusting capability, can be used for preserving foods such as drinks, vegetables, fruits, fresh meat and the like, but cannot be used for freezing meat or ice cream.
