[0017] The following further elaborates on the present utility model in conjunction with the accompanying drawings.

[0018] The following further illustrates the specific implementation manners of the present utility model in conjunction with the accompanying drawings. Among them, the same components are denoted by the same reference numerals.

[0019] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0020] In order to make the content of the present utility model more clearly understood, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] Combined with the attached Figure 1 - attached Figure 4 , a drainage device for a cold air blower, comprising a drain pipe main body connected to the bottom of the cold air blower 1. The drain pipe main body includes an inclined pipe 2. The upper end of the inclined pipe 2 is connected to the bottom of the cold air blower 1 through a first elbow 3. The lower end of the inclined pipe 2 is connected to a first straight pipe 6 that penetrates to the outside of the cold storage wall 5 through a second elbow 4. The outer end of the first straight pipe 6 is connected to a first vertical pipe 8 through a third elbow 7. A U-shaped elbow 9 is provided at the lower end of the first vertical pipe 8. One end of the U-shaped elbow 9 away from the first vertical pipe 8 is provided with a second vertical pipe 10. The second vertical pipe 10 away from the U-shaped elbow 9 is connected to a second straight pipe 12 through a fourth elbow 11.

[0022] In one embodiment, an installation port 13 is provided on the second elbow 4. A detachable mounting seat 14 is provided on the installation port 13. An electric heat tracing 15 is provided on the mounting seat 14. One end of the electric heat tracing 15 extends along the length direction of the inclined pipe 2 to the upper end of the inner cavity of the inclined pipe 2. The role of the electric heat tracing 15 in preventing condensed water from freezing is particularly emphasized. When the cold air blower 1 operates in a low-temperature environment, the condensed water generated at its bottom is likely to freeze in the drainage path, resulting in poor drainage or even blockage. To solve this problem, an installation port 13 is provided on the second elbow 4 in this embodiment, and a detachable mounting seat 14 is equipped. The electric heat tracing 15 installed on the mounting seat 14 is tightly connected to the second elbow 4 through a spiral sleeve 16 and extends along the length direction of the inclined pipe 2 to the upper end of its inner cavity, ensuring that the heating effect covers the condensed water entry point. When the electric heat tracing 15 is turned on, it can effectively raise the temperature of the inclined pipe 2 and the surrounding area, prevent condensed water from freezing at low temperatures, and thus ensure the smooth operation of the drainage system. At the same time, the outer end of the electric heat tracing 15 is connected to a junction box 20 outside the cold air blower 1 through a connection wire 19, facilitating centralized control and power supply.

[0023] And in the middle of the spiral sleeve 16, a central seat 17 is rotatably provided. This design allows the central seat 17 to freely rotate within the spiral sleeve 16, providing greater flexibility and convenience for the installation and adjustment of the electric tracing 15. The opening provided on the central seat 17 is for accommodating the T-shaped plug 18, thereby fixing the electric tracing 15 in place. The design of the T-shaped plug 18 is very ingenious, and its shape and size match the opening on the central seat 17, ensuring that the electric tracing 15 can be firmly inserted inside the T-shaped plug 18. This insertion method not only simplifies the installation process of the electric tracing 15 but also improves the reliability and stability of its connection. When the electric tracing 15 needs to be replaced, the user only needs to gently pull out the old electric tracing 15 from the T-shaped plug 18 and then insert the new electric tracing 15, without the need to disassemble or make large-scale modifications to the entire mounting seat 14.

[0024] In one embodiment, a section of the drain pipe body located inside the cold storage wall 5 is wrapped with a heat insulation layer 23. In order to reduce heat loss, improve the working efficiency of the drainage system and reduce energy consumption, in this embodiment, the part of the drain pipe body located inside the cold storage wall 5 is wrapped with a heat insulation layer 23. This heat insulation layer can not only effectively isolate the influence of the external temperature on the condensed water but also maintain the temperature stability inside the drainage path, preventing the condensed water from freezing or evaporating due to temperature fluctuations during transmission.

[0025] In one embodiment, the lower end of the U-shaped elbow 9 is provided with a liquid discharge port, and a sealing cover 24 is threadedly connected to the liquid discharge port. The design of the U-shaped elbow 9 ingeniously combines the gravity of the condensed water itself and the sealing performance to form an effective barrier to isolate the entry of external hot air (especially hot air rich in water vapor) into the cold storage. This design not only significantly reduces the risk of frosting on the fin of the cooling fan, the fan housing and the blades due to contact with hot air, but also protects the fan from damage and effectively reduces the operating load of the cold storage equipment. In addition, the liquid discharge port and the sealing cover 24 provided at the bottom of the U-shaped elbow 9 provide a convenient way for users to perform regular maintenance and clean the accumulated condensed water, further improving the reliability and safety of the drainage system. At the same time, this design also fully considers the maintainability and scalability of the system, facilitating subsequent upgrades, transformations and fault troubleshooting.

[0026] Working principle: When the cold air blower drainage device of the present application is working, first, the condensed water generated at the bottom of the cold air blower 1 is discharged through a carefully designed drainage path. The condensed water is first guided to the inclined pipe 2 through the first elbow 3 and flows naturally along its inclined direction to the lower end. Subsequently, the condensed water enters the second elbow 4. During this process, if it is necessary to prevent freezing problems in a low-temperature environment, heating treatment can be carried out through the electric tracing 15 on the mounting seat 14 to ensure the smooth flow of the condensed water.

[0027] Next, the condensed water passes through the first straight pipe 6 and penetrates the cold storage wall 5. During this process, the sealing performance of the first straight pipe 6 is crucial to prevent the penetration of external air. Subsequently, the condensed water enters a special structure composed of the first vertical pipe 8 and the U-shaped elbow 9. The main function of the U-shaped elbow 9 is to form a water seal, that is, by utilizing the gravity and sealing performance of water itself, it effectively isolates the external hot air (especially the hot air rich in water vapor) from entering the cold storage interior. This design avoids the direct contact between the hot air and the cooling fan, thereby reducing the risk of frosting on the fins of the cooling fan, the fan housing and the blades, protecting the fan from damage, and reducing the operating load of the cold storage equipment.

[0028] In addition, the drain port and the sealing cover 24 provided at the bottom of the U-shaped elbow 9 not only facilitate regular maintenance and cleaning of the accumulated condensed water, but also further enhance the reliability and safety of the entire drainage system.

[0029] The entire main body of the drain pipe, especially the part located inside the cold storage wall 5, is wrapped with a heat insulation layer 23 to reduce heat dissipation, ensure the efficient operation of the drainage system, and reduce energy consumption.

[0030] The above describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the gist of the creation of the present utility model, they design similar structural modes and embodiments to this technical solution without creative efforts, which shall fall within the protection scope of the present utility model.
