The main structure of the refrigerator drawer is that a plastic inlaid metal cold-conducting disc nine-grid refrigerating assembly is arranged at the top of the refrigerator drawer, corresponding air channels and air doors are arranged for each metal cold-conducting disc grid, the temperature sensor detects the temperature of a drawer compartment, and different numbers of nine-grid air door switches can be controlled at any time according to different temperature requirements of foods and the detected temperature of the drawer compartment, so that guarantee is provided for storage and preservation of the foods, and loss of moisture and nutrition caused by direct blowing of the foods by wind is avoided. The working principle of the nine-grid refrigerating assembly is that when the refrigerator drawer is cooled, cold air is transmitted to an air channel formed between the air door set and the cold guide disc through the air door set, and the cold guide disc is cooled so as to cool the refrigerator drawer. The control module can adjust the indoor temperature of the refrigerator drawer by adjusting the opening amount of the air door set according to the temperature required by the stored food. Specifically, the control module firstly controls the nine-grid refrigerating assembly to operate with the opening number of the air door groups as the first number, so that the indoor temperature of the refrigerator drawer is kept at 2-3 ℃ for three hours, meat food is in a uniform temperature state, and the temperature of the meat food can be reduced better and more uniformly. And then controlling the nine-grid refrigerating assembly to operate with the opening number of the air door groups as a second number, so that the indoor temperature of the refrigerator drawer is kept at-3 to-5 ℃ for two hours, and the supercooling state is carried out, so that an ice film is formed on the surface of meat food, and the damage to the meat food caused by instant low temperature is avoided. And then controlling the nine-grid refrigerating assembly to operate with the opening number of the air door groups as a third number, so that the indoor temperature of the refrigerator drawer is kept at-37 to-39 ℃.

The temperature sensor detects the indoor temperature of the refrigerator drawer at intervals, when the indoor temperature is detected to be lower than 2 ℃, the indoor temperature is too low, and at the moment, the control module controls any one of the opened air doors to be closed, so that the indoor temperature of the refrigerator drawer is increased to be between 2 and 3 ℃. When the indoor temperature is detected to be between 2 and 3 ℃, the current state is maintained. When the indoor temperature is detected to be higher than 3 ℃, the indoor temperature is too high, and at the moment, the control module controls any one of the closed air doors to be opened, so that the indoor temperature of the refrigerator drawer is reduced to be between 2 and 3 ℃. This stage requires the control module to maintain the indoor temperature of the refrigerator drawer between 2 and 3 c for three hours by controlling the opening and closing of the nine dampers.

As an alternative example, the control module is further configured to control the second number of dampers of the damper group to open after the nine-grid refrigeration assembly operates for a first period of time with the open number of dampers being the first number, to control the open number of dampers to decrease by one if the minimum temperature of the indoor temperature is detected to be less than the second temperature interval, to maintain the indoor temperature in the second temperature interval, and to control the open number of dampers to increase by one if the maximum temperature of the indoor temperature is detected to be greater than the second temperature interval.

The temperature sensor detects the indoor temperature of the refrigerator drawer at intervals, when the indoor temperature is detected to be lower than-5 ℃, the indoor temperature is too low, and at the moment, the control module controls any one of the opened air doors to be closed, so that the indoor temperature of the refrigerator drawer is increased to be between-3 ℃ and-5 ℃. When the indoor temperature is detected to be between-3 ℃ and-5 ℃, the current situation is maintained. When the indoor temperature is detected to be higher than-3 ℃, the indoor temperature is too high, and at the moment, the control module controls any one of the closed air doors to be opened, so that the indoor temperature of the refrigerator drawer is reduced to be between-3 ℃ and-5 ℃. This stage requires the control of the opening and closing of the nine dampers by the control module to maintain the indoor temperature of the refrigerator drawer between-3 and-5 ℃ for two hours.

The temperature sensor detects the indoor temperature of the refrigerator drawer at intervals, when the indoor temperature is detected to be lower than-39 ℃, the indoor temperature is too low, and at the moment, the control module controls any one of the opened air doors to be closed, so that the indoor temperature of the refrigerator drawer is increased to be between-37 ℃ and-39 ℃. When the indoor temperature is detected to be between minus 37 ℃ and minus 39 ℃, the current situation is maintained. When the indoor temperature is detected to be higher than-37 ℃, the indoor temperature is overhigh, and the control module keeps all nine air doors open until the indoor temperature of the refrigerator drawer is reduced to be between-37 ℃ and-39 ℃. This stage requires the control of the opening and closing of the nine dampers by the control module to maintain the indoor temperature of the refrigerator drawer between-37 and-39 ℃ for three hours.
