In the embodiment of the present invention, as shown in fig. 6 and 7, an airflow guiding plate 5 for separating two adjacent air outlets 11, that is, two adjacent air outlet regions, is disposed between the ice storage liner 1 and the ice storage housing 2, the airflow guiding plate 5 extends along the airflow direction, the airflow direction flows from one side wall of the ice storage liner 1 through the bottom wall and the opposite side wall, and divides the air interlayer into a plurality of independent airflow channels 6, so as to guide the airflow to flow along the respective airflow channels 6 after flowing out from the corresponding air outlet regions, the airflow channels 6 pass through the outer wall of the air outlet 11 side of the ice storage liner 1, then flow through the bottom of the ice storage liner 1, and then flow through the outer wall of the ice storage liner 1 near the air inlet 3 side from the bottom, and then flow out from the air return port 22 of the ice storage housing 2, so that the periphery of ice cubes in the ice storage liner 1 is completely surrounded by low temperature airflow, the ice cube is provided with a stable and uniform low-temperature environment, and the problem that the local temperature of the ice cube is too high due to non-uniform airflow is solved.
In the embodiment of the present invention, specifically, the airflow guide plate 5 extends downward from the side wall of the ice storage liner 1 opposite to the ice storage housing 2 and passes through the bottom of the ice storage liner 1 opposite to the ice storage housing 2. The airflow guide plate 5 can continue to extend from the bottom to the side wall between the ice storage liner 1 and the ice storage housing 2, where the air inlet 3 is arranged, but the length of the extension needs to be determined according to the setting condition of the air return opening 22, for example, when all the airflow channels 6 share the air return opening 22, that is, a plurality of the airflow channels 6 are all communicated with the same air return opening 22, the length of the upward extension of the airflow guide plate 5 needs not to exceed the height of the air return opening 22, forming a similar L shape, as shown in fig. 7, to form an airflow junction area at the air return opening 22, so that the airflow of each airflow channel 6 can flow out from the air return opening 22 after being merged; when each airflow channel 6 corresponds to one air return opening 22, namely the side wall of the ice storage shell 2 is provided with the air return opening 22 communicated with each airflow channel 6, the airflow guide plate 5 can extend upwards to the top to form a U-shaped structure so as to separate the airflow channels 6, and the airflow of each airflow channel 6 flows out of the air return opening 22 of the airflow channel 6; the specific setting mode can be set according to the requirements of users.

In the embodiment of the invention, the ice discharging mechanism 4 is arranged in the ice storage liner 1, the side wall of the ice storage liner 1 is provided with an ice outlet 12, if ice discharging requirements exist, the ice discharging mechanism 4 outputs ice blocks 7 through the ice outlet 12, the ice discharging mechanism 4 can be a rotating shaft and a helical blade arranged on the rotating shaft, and the helical blade is driven to rotate by the rotating shaft, so that the ice blocks 7 are pushed to move towards the ice outlet 12 until the ice blocks 7 are pushed out of the ice outlet 12; if there is no need for ice production, the ice cubes 7 will be stored in the ice bank.
On the other hand, the embodiment of the invention also provides a refrigerating device, which comprises but is not limited to a refrigerator, an air supply duct and the ice storage box in the technical scheme; as shown in fig. 1 to 7, the air supply duct is communicated with the air inlet 3 of the ice storage box, an air door, which may be an electric air door, is disposed at an outlet of the air supply duct, an ice amount sensor is disposed in the ice storage box and used for detecting the amount of ice stored, the ice amount sensor is in signal connection with a control system of the refrigeration equipment, which may also be in line connection, and the control system adjusts the opening degree and/or the air supply time of the air door according to the amount of ice stored in the ice storage box detected by the ice amount sensor; to achieve dynamic control of the flow of the gas stream.
Specifically, the air outlet area of the air outlet 11 is different and the flow resistance of the whole airflow is different with the different storage amounts of the ice cubes 7 in the ice storage box, when the number of the ice cubes 7 is large, the airflow flow resistance is large, the required cold quantity is large, and at the moment, airflow with large pressure and low temperature is required; when the ice cubes 7 are fewer, the area of the air outlet 11 is large, the airflow resistance is small, the required cold quantity is also small, and the corresponding input airflow pressure is reduced and the cold quantity is reduced. Thus, the opening size of the air door for controlling air intake and the air supply time can be dynamically adjusted and controlled according to the amount of the ice stored in the ice storage box, for example, as shown in fig. 8, the storage amount of ice cubes is judged firstly, if the storage amount of the ice cubes is less than a critical lower limit, the opening degree of the air door is controlled to be reduced or the air supply time is controlled to be reduced, the supply cold amount of the air supply channel is reduced, if the storage amount of the ice cubes is more than a critical upper limit, the opening degree of the air door is controlled to be increased or fully opened, and the air supply channel supplies cold normally; the ice storage box solves the problem of temperature control in the ice storage box, and prevents ice blocks from melting due to high local temperature in the ice storage box.
In the embodiment of the invention, an evaporator for supplying cold to the air supply duct is further arranged, the air of the air supply duct blows over the evaporator, the cold energy of the evaporator is carried in the air flow and blown to the ice storage liner 1 to provide the cold energy for the ice blocks, and the control system dynamically adjusts the temperature of the evaporator according to the ice storage amount (the height of the ice storage amount) in the ice storage box detected by the ice amount sensor so as to reduce the energy consumption of the refrigeration equipment; specifically, the evaporator compresses a refrigerant by a compressor and supplies the refrigerant to the evaporator through throttling and pressure reduction, so that the temperature of the evaporator can be controlled by controlling the opening frequency of the compressor; the temperature of the evaporator, the opening size of the air door and the air supply time can be selected and controlled to be combined with one or more combinations for combined control, so that the utilization efficiency of the refrigerating capacity of the refrigerating equipment is improved, and the energy consumption is optimized.
The embodiment can show that the ice cube forming machine can provide a stable and uniform low-temperature environment for ice cubes, avoid melting and adhesion of the ice cubes and ensure that the ice cubes are in good shape; and the air inlet quantity, the air supply time and the temperature of the evaporator can be dynamically adjusted and controlled, the utilization efficiency of the refrigerating capacity of the refrigerating equipment is improved, and the energy consumption is optimized.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
