[0033] Reference Figure 1-5 A constant temperature control device for cold storage is used for temperature control of cold storage to facilitate the control of the internal temperature of the cold storage and avoid the impact of newly stored goods on other goods.

[0034] The constant temperature control device for cold storage comprises a cold storage body 1, a plurality of placement boxes 6, a plurality of ventilators 9 and a refrigerator 3;

[0035] A plurality of air blowers 2 are provided at the top of the interior of the cold storage body 1, a fan is provided inside the air blower 2, a refrigerator 3 is provided inside the cold storage body 1, an evaporative condenser is provided inside the refrigerator 3, an air compressor 4 is provided outside the cold storage body 1, the air compressor 4 is connected to the evaporative condenser of the refrigerator 3 to provide refrigerant to the evaporative condenser, thereby cooling the air passing through the refrigerator 3, the air outlet of the refrigerator 3 is connected to the air blower 2 through a pipeline, and the air inlet is connected to each placement box 6 through a pipeline, so that the air inside the cold storage body 1 can be extracted through the placement box 6 and sent to the refrigerator 3 for cooling and cooling, and then discharged into the cold storage body 1 through the air blower 2, so that the air inside the cold storage body 1 is circulated, and a three-way valve 5 is provided between the placement box 6 and the refrigerator 3, the three-way valve 5 is a three-way solenoid valve, which can control the air inside the cold storage body 1 to directly enter the refrigerator 3 for cooling without passing through the placement box 6.

[0036] A plurality of placement boxes 6 are arranged inside the cold storage body 1, and a placement plate 8 is provided on the top of each placement box 6. The placement plate 8 is used to place goods 7. A plurality of through holes are opened on the placement plate 8. Each ventilation tube 9 is slidably connected in a through hole, and the top protrudes from the placement plate 8. A vent 902 is provided on the bottom of one side of each ventilation tube 9. Each ventilation tube 9 is distributed in a matrix shape. When placing goods, the goods 7 will be supported by the plurality of matrix-shaped ventilation tubes 9. Due to the gravity of the goods 7, each ventilation tube 9 will be pressed down, so that the vent 902 is moved out of the through hole of the placement plate 8, so that the internal space of the placement box 6 is connected with the external space, and at this time, the air inside the cold storage body 1 is sucked in through the ventilation tube 6. The goods 7 are placed in the placement box 6 and then enter the refrigerator 3 for circulation. Since the goods 7 are located above each ventilation tube 9, the heat emitted by the goods 7 will be directly brought into the placement box 6 by the flowing airflow, and then cooled by the refrigerator 3, thereby avoiding the impact of the goods 7 just put into the warehouse on other goods. In addition, since a serrated ventilation groove 901 is provided at the upper end of each ventilation tube 9, when the goods 7 are located on the ventilation tube 9, the inside and outside of the ventilation tube 9 are connected through the ventilation groove 901, thereby facilitating the absorption of heat from the goods 7. Each air outlet fan 2 is located directly above a placement box 6, thereby forming convection, which facilitates the air to take away the heat of the goods 7 just put into the warehouse, thereby ensuring a constant temperature environment for other goods.

[0037] The interior of the placement box 6 is fixedly connected with a fixed plate 11, and the interior of the placement box 6 is slidably connected with a movable plate 10. An opening is provided in the middle of the movable plate 10, and each ventilator 9 is fixedly connected to the movable plate 10. A return spring 12 is provided at the bottom of the movable plate 10, and the lower end of the return spring 12 is fixedly connected to the fixed plate 11. A mounting opening is provided on the fixed plate 11, and a filter screen 13 is provided in the mounting opening, and the connection port between the placement box 6 and the refrigerator 3 is located below the filter screen 13. When the ventilator 9 is pressed down by the gravity of the goods 7, the movable plate 10 will be driven down, thereby compressing the return spring 12. If no goods are stored on the ventilator 9, the return spring 12 will push the ventilator 9 into the through hole of the placement plate 8. At this time, the ventilator 902 enters the through hole of the placement plate 8 and fits with the inner wall of the through hole, so that the ventilator 9 is closed, and the inner and outer spaces of the placement box 6 are separated. Therefore, the air circulation effect of the placement box 6 storing goods 7 in other areas can be enhanced, which is convenient for the goods 7 that have just entered the warehouse to quickly cool down.

[0038] The working principle of the constant temperature control device for cold storage:

[0039] The goods 7 that have just entered the warehouse are placed on the placement plate 8. Due to the gravity of the goods 7, the ventilation tube 9 on the placement plate 8 will be pressed down, so that the lower end of the ventilation tube 9 enters the interior of the placement box 6, so that the ventilation port 902 moves out of the through hole of the placement plate 8, and the internal space of the placement box 6 is connected with the external space. At this time, the air inside the cold storage body 1 first enters the ventilation tube 9 through the ventilation slot 901, and then enters the placement box 6 through the ventilation port 902. The air entering the placement box 6 will first pass through the opening of the movable plate 10, and then be filtered by the filter 13 to remove dust and foreign matter, and finally pass through the The goods 7 enter the refrigerator 3 through the connected pipes, and the refrigerator 3 cools the incoming air, and finally is discharged into the cold storage body 1 through the air outlet fan 2 for circulation. Since the goods 7 are above each ventilation duct 9, the heat emitted by the goods 7 will be directly brought into the placement box 6 by the flowing airflow, and then cooled by the refrigerator 3, so as to avoid the goods 7 just put into the warehouse from affecting other goods. Moreover, since each air outlet fan 2 is located directly above a placement box 6, convection is formed, which facilitates the air to take away the heat of the goods 7 just put into the warehouse, and ensures the constant temperature environment of other goods.

[0040] When the goods 7 do not need to be cooled quickly, the pipeline can be controlled by the three-way solenoid valve 5 so that the refrigerator 3 directly inhales the air inside the cold storage body 1 without passing through the placement box 6, thereby increasing the air circulation speed and ensuring the constant temperature effect of the cold storage body 1.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
