The provision of multiple air outlets 11 can facilitate the determination of the height and size of the air outlet surface according to the amount of ice storage, without causing ice Blocks block the air outlet surface. For example, when the ice storage volume is small, the multiple outlet air outlet 11 located above the ice cube is used as the air outlet surface. The air outlet surface is larger, and the wind resistance is small at this time. When the ice storage volume is large, it is located in the ice block The air outlet 11 in the upper row is used as the air outlet surface, the air outlet surface is small, and the wind resistance is large at this time; the shape of the air outlet 11 can be set according to specific requirements, and can be long, square, round, or oval.

Of course, it may also be installed on the ice storage tank 1. The outer wall of the ice storage shell 2 and the inner wall of the ice storage shell 2 are both provided, and the specific installation form is not limited. In this embodiment, for the convenience of installation, the airflow guide plate 5 is preferably provided on the outer wall of the ice storage tank 1.

In the embodiment of the present application, the ice storage liner 1 is provided with an ice ejection mechanism 4, and the side wall of the ice storage liner 1 is provided with an ice ejection port 12.

The ice outlet mechanism 4 may specifically be a rotating shaft and a spiral blade provided on the rotating shaft. The spiral blade is driven to rotate by the rotating shaft, thereby pushing the ice block 7 to move toward the ice outlet 12 until the ice The block 7 is pushed out of the ice outlet 12; if there is no demand for ice out, the ice block 7 will be stored in the ice storage box.

On the other hand, the embodiment of the present application also provides a refrigeration device, including but not limited to a refrigerator, provided with an air supply duct and the ice storage box described in the above technical solution; as shown in Figures 1 to 7, The air supply air duct is connected to the air inlet 3 of the ice storage box, the outlet of the air supply air duct is provided with a damper, which may be an electric damper, and the ice storage box is provided with an ice volume sensor for detecting The size of the ice storage capacity, the signal connection between the ice volume sensor and the control system of the refrigeration equipment can of course also be a line connection, and the control system is based on the ice storage in the ice storage box detected by the ice volume sensor.

Specifically, as the storage amount of ice cubes 7 in the ice storage box is different, the air outlet area of the air outlet 11 is also different, and the flow resistance of the entire air flow is also different. When there are more ice cubes 7, the air flow resistance is large, which is required There is a lot of cold capacity, and airflow with higher pressure and lower temperature is required at this time; when there are fewer ice cubes 7, the air outlet 11 area is large, the airflow resistance is small, and the required cooling capacity is also less. The amount is reduced. In this way, according to the amount of ice stored in the ice storage box, the size of the opening of the air door and the air supply time can be dynamically adjusted, as shown in Figure 8. For example, first determine the storage capacity of ice cubes, if the storage capacity of ice cubes is small At the critical lower limit, the control damper opening is reduced or the air supply time is reduced, and the air supply duct reduces the supply of cold capacity. If the ice storage capacity is greater than the critical upper limit, the control damper opening is increased or fully opened, and the air supply duct is normal Cooling, thereby improving the utilization efficiency of the cooling capacity of the refrigeration equipment and optimizing energy consumption; solving the temperature control problem in the ice storage box, preventing the ice from melting due to high local temperatures in the ice storage box.

In the embodiment of the present application, an evaporator for cooling the air supply duct is also provided. The wind from the air supply duct blows through the evaporator to carry the cold energy of the evaporator in the airflow and blow it into the ice storage. Tank 1 provides cold capacity for ice cubes, and the control system dynamically adjusts the evaporator according to the amount of ice stored in the ice storage box (the height of the ice cube storage capacity) detected by the ice quantity sensor In order to reduce the energy consumption of refrigeration equipment; specifically, the evaporator compresses the refrigerant by the compressor and supplies it to the evaporator through throttling and pressure reduction, so that the temperature of the evaporator can be controlled by controlling the start frequency of the compressor; the temperature of the evaporator , The size of the air door opening and the air supply time can be selected to control one or more combinations for joint control to improve the utilization efficiency of the cooling capacity of the refrigeration equipment and optimize the energy consumption.
