Fresh keeping refrigerator and control method thereof

Abstract

The invention discloses a fresh keeping refrigerator, and relates to the technical field of home appliances. The fresh keeping refrigerator comprises a cold storage chamber, a temperature changing chamber, a freezing chamber and a refrigeration system. A fresh keeping agent releasing device is arranged in the temperature changing chamber and comprises a liquid storage device and a motor, and the liquid storage device is of a cylinder structure. A motor is arranged at the inner top of the liquid storage device, the output end of the motor is provided with a piston capable of moving along the inner wall of the liquid storage device, and micro holes are evenly distributed in the bottom side face of the liquid storage device. The liquid storage device is filled with a fresh keeping agent. A draught fan and a temperature sensor are further arranged in the temperature changing chamber. A controller arranged at any position outside the refrigerator is further included. The signal receiving end of the controller is connected with the temperature sensor, and the signal output end of the controller is connected with the motor and the draught fan. The fresh keeping refrigerator utilizes the character that the antifreeze protein has a very good heat stagnation effect, and the freezing point of food materials is reduced, the antifreeze protein is utilized for conducting food material freezing and fresh keeping, and the effect of freezing and fresh keeping of the food materials through the refrigerator is improved.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a fresh-keeping refrigerator and a control method of the fresh-keeping refrigerator. Background technique [0002] With the improvement of living standards, consumers have higher requirements for the freshness of ingredients. Refrigerators are the main food storage appliances for households, and their ability to keep fresh has attracted much attention. Under the freezing conditions of the refrigerator, the activity of bacteria and enzymes can be greatly reduced, so that the food can be stored for a long time without spoilage. However, if the freezing temperature is too low, a large number of ice crystals will be formed in the food, and the nutrients will be lost. At the same time, the thawing time will be longer, which will increase the pain points of users. . Antifreeze protein can have a good thermal hysteresis effect and lower the freezing point of i...
