Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, specifically to a hot-fluorine defrosting refrigeration unit. Background Technology

[0002] Hot-fluorine defrosting refrigeration units are devices that use high-temperature, high-pressure refrigerant gas to directly introduce into the evaporator for defrosting. Compared with traditional electric heating defrosting methods, hot-fluorine defrosting is more efficient and energy-saving, effectively shortening defrosting time, reducing energy consumption, and protecting the evaporator surface from damage. This system is widely used in low-temperature environments such as cold storage and food processing, and is especially suitable for occasions with strict temperature requirements and high operational stability.

[0003] Common hot-frosting refrigeration units require efficient heat dissipation during operation. Therefore, the units are usually equipped with long-term running air-cooled cooling fans and filters to ensure stable heat dissipation from the condenser. However, when replacing the filters at the air inlet and outlet of most units, it is difficult to ensure that they fit snugly against the bottom opening of the casing due to the difficulty in observing from the bottom. This results in poor sealing or edge leakage, reducing filtration efficiency. Utility Model Content

[0005] Therefore, one objective of this utility model is to provide a hot-frozen defrosting refrigeration unit. This unit allows the filter frame to be raised and lowered by adjusting the threaded rod, facilitating the removal or installation of the filter screen on the filter frame. By rotating the threaded rod in the opposite direction, the filter screen is raised and fitted to the opening at the bottom of the casing, thus completing the installation of the refrigeration unit's filter screen and facilitating equipment maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot-frozen defrosting refrigeration unit, including a casing, inside which a refrigeration unit body is installed, a cooling fan is installed on the top of the casing, four threaded rods are symmetrically penetrating the inner wall of the bottom of the casing, four fixing plates are symmetrically installed on the inner wall of the casing, and internally threaded cylinders are embedded in the fixing plates. The threaded rods are threadedly connected to the inside of the internally threaded cylinders, and a filter frame is penetrating the outer wall of the threaded rods.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-2 An embodiment of this utility model provides a hot-frosting refrigeration unit, including: a casing 1 and a refrigeration unit body 8.

[0020] Among them, such as Figure 1 and Figure 2 As shown, the refrigeration unit body 8 is installed inside the chassis 1. A cooling fan 2 is installed on the top of the chassis 1. A mesh cover 3 is provided on the top of the chassis 1. The cooling fan 2 is located inside the mesh cover 3. When the refrigeration unit body 8 is running in a cooling mode, the heat generated is discharged by the cooling fan 2 installed on the top of the chassis 1. The mesh cover 3 can prevent the cooling fan 2 from being directly exposed to the external environment.

[0021] In this embodiment, as Figures 1-4 As shown, four threaded rods 5 are symmetrically inserted through the bottom inner wall of the chassis 1. Four fixing plates 12 are symmetrically installed on the inner wall of the chassis 1. An internal threaded cylinder 13 is embedded in the fixing plate 12. The threaded rods 5 are threadedly connected to the inside of the internal threaded cylinder 13. A filter frame 6 is inserted through the outer wall of the threaded rods 5. Two positioning grooves 11 are symmetrically provided on the top of the filter frame 6. A filter screen 7 is provided on the positioning groove 11. An opening matching the shape of the filter screen 7 is provided at the bottom of the chassis 1.

[0022] In use, the filter frame 6 can be raised and lowered by rotating the threaded rod 5. When the filter screen 7 needs to be removed, rotating the threaded rod 5 lowers the filter frame 6, thus keeping the filter screen 7 on the outside for easy removal by the operator. When replacing or installing the filter screen 7, the operator places the filter screen 7 directly on the filter frame 6 and places both sides of the filter screen 7 into the positioning groove 11 to prevent the filter screen 7 from sliding or shifting. By rotating the threaded rod 5 in the opposite direction, the filter frame 6 is raised and attached to the bottom of the housing 1, causing the filter screen 7 to be attached to the opening at the bottom of the housing 1.

[0023] Furthermore, a pad 10 is passed through the threaded rod 5. The pad 10 is located at the bottom of the filter frame 6. The pad 10 can increase the contact area with the bottom of the filter frame 6, avoid the filter frame 6 from directly contacting the end of the threaded rod 5, and improve the stability of the filter frame 6.

[0024] like Figure 4 As shown, in order to prevent the threaded rod 5 from falling out of the internal threaded cylinder 13, a nut 9 is threadedly connected to the top end of the threaded rod 5, and the outer diameter of the nut 9 is larger than the inner diameter of the internal threaded cylinder 13.

[0025] Specifically, a base bracket 4 is fixedly connected to the bottom of the chassis 1, which can provide support and stability for the chassis 1.

[0026] Based on the above technical solution, the working steps of this solution are summarized as follows: The hot fluorine defrosting refrigeration unit operates through the refrigeration unit body 8, and the generated heat is discharged by the cooling fan 2 installed on the top of the casing 1. The bottom of the casing 1 is provided with a threaded rod 5 and a filter screen 7, and the threaded rod 5 is threadedly connected to the internal threaded cylinder 13 inside the casing 1.

[0027] The filter frame 6 can be raised and lowered by rotating the threaded rod 5. When the filter screen 7 needs to be removed, rotating the threaded rod 5 lowers the filter frame 6, thus keeping the filter screen 7 on the outside for easy removal by the operator. When replacing or installing the filter screen 7, the operator places the filter screen 7 directly on the filter frame 6 and places both sides of the filter screen 7 into the positioning groove 11 to prevent the filter screen 7 from sliding or shifting. By rotating the threaded rod 5 in the opposite direction, the filter frame 6 is raised and fitted against the bottom of the casing 1, causing the filter screen 7 to fit against the opening at the bottom of the casing 1, thus facilitating the removal and installation of the refrigeration unit filter screen 7 and making equipment maintenance convenient.

[0028] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
