Description

Technical Field

[0001] This utility model relates to the field of freezers, and more particularly to a commercial freezer with a rapid defrosting water evaporation mechanism. Background Technology

[0002] Refrigeration equipment includes refrigeration cabinets, freezer compartments, and freezer boxes. Refrigeration cabinets are mainly used for refrigerating and freezing beverages, frozen foods, and ingredients. They include the cabinet body and the refrigeration and control systems inside the cabinet. The defrost water produced by the refrigeration system of existing refrigeration cabinets mainly evaporates by itself, which has a low evaporation efficiency. Over time, this can cause corrosion damage to the components inside the mechanical room. Furthermore, after long-term operation, commercial freezers will accumulate a large amount of defrost water in the defrost water box inside the cabinet due to the poor self-evaporation efficiency.

[0003] In existing technology, defrosting water is usually collected in a water tank installed inside the freezer's refrigeration unit and then discharged through an external water pipe connected to the water tank. Users either use a water storage device to collect the defrosting water discharged from the freezer and empty it in time, or let the defrosting water flow onto the ground. Collecting and frequently emptying the defrosting water unnecessarily increases the user's burden, while defrosting water flowing onto the ground seriously affects the aesthetics and may cause dangers such as electric leakage. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a commercial freezer with a rapid defrosting water evaporation mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A commercial freezer with a rapid defrosting water evaporation mechanism includes a cylindrical shell, a collection tray, an air guide assembly, and a recovery base plate. The cylindrical shell is disposed within an evaporation chamber inside the freezer. The collection tray has an upward-opening liquid collection chamber. The air guide assembly includes a central rotating rod, an extension beam, and water-absorbing blades. The bottom end of the central rotating rod is coaxially mounted to the rotating shaft of a drive motor. The extension beams are symmetrically mounted on the bottom outer peripheral wall of the central rotating rod. Water inlet beams are symmetrically mounted on the top outer peripheral wall of the central rotating rod. Each water inlet beam is angularly offset from the extension beam. The upper and lower surfaces of the water-absorbing blades are connected to the staggered water inlet beams and extension beams, respectively, thereby causing the water-absorbing blades to be torsional and offset around the outer periphery of the central rotating rod. The recovery base plate has a recovery groove, and the drive motor is mounted in the recovery groove.

[0007] Preferably, the outer peripheral walls at the upper and lower ends of the cylindrical shell are respectively provided with an air inlet and an air outlet. The isolation plate set in the evaporation chamber isolates the evaporation chamber into two spaces that can only be connected through the cylindrical shell. The refrigeration compartment of the freezer is connected to the upper part of the evaporation chamber, and the lower part of the evaporation chamber is connected to the outside of the freezer through an external window.

[0008] Preferably, the depth of the liquid collection chamber gradually decreases from the center to the outside, and several guide pipes are arranged on the upper surface of the water inlet beam, with the upper and lower ends of the guide pipes connected to the liquid collection chamber and the lower surface of the water inlet beam, respectively.

[0009] Preferably, the water-absorbing blades are made of rigid water-absorbing material, the freezer's cooling compartment has an air inlet window, the freezer's cooling compartment is connected to the upper area of ​​the evaporation chamber, and the air outlet is located above the recovery tank.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The defrosting water in this refrigerator is collected by the collection tray and then distributed to the water-absorbing blades. It is then quickly evaporated by the airflow inside the cylindrical shell and discharged from the refrigerator. The water-absorbing blades can serve as both fan blades and evaporation surfaces for the defrosting water, greatly improving the evaporation efficiency of the defrosting water. The refrigerator's defrosting water is discharged through evaporation, which eliminates the need for frequent drainage by the user and avoids affecting the aesthetics or causing danger due to water being discharged on the ground.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Reference Figure 1 and 2 A commercial freezer with a rapid defrosting water evaporation mechanism includes a cylindrical shell 1, a collection tray 2, an air guide assembly 3, and a recovery base plate 4. The collection tray 2 is installed on the top of the cylindrical shell 1, and the air guide assembly 3 is installed on the bottom of the recovery base plate 4. The outer peripheral walls at the upper and lower ends of the cylindrical shell 1 are respectively provided with an air inlet 101 and an air outlet 102. The cylindrical shell 1 is disposed in an evaporation chamber 100 inside the freezer. An isolation plate 11 disposed in the evaporation chamber 100 divides the evaporation chamber 100 into two spaces that can only be connected through the cylindrical shell 1. The freezer's cooling compartment is connected to the upper part of the evaporation chamber 100, and the lower part of the evaporation chamber 100 is connected to the outside of the freezer through an external window 103.

[0018] The collection tray 2 has an upward-opening liquid collection chamber 201. The defrosting water generated by the freezer's cooling compartment flows into the liquid collection chamber 201 through the drain pipe 12 for temporary collection. The depth of the liquid collection chamber 201 gradually decreases from the center to the outside, so that the defrosting water entering the liquid collection chamber 201 first gathers at the center of the liquid collection chamber 201, and gradually spreads to the edge of the liquid collection chamber 201 as the amount of defrosting water increases.

[0019] The air guide assembly 3 includes a central rotating rod 31, an extension beam 32, and water-absorbing blades 33. The bottom end of the central rotating rod 31 is coaxially mounted to the rotating shaft of a drive motor 34, so that the drive motor 34 can drive the central rotating rod 31 to rotate axially. The extension beam 32 is symmetrically mounted on the bottom outer peripheral wall of the central rotating rod 31. Water inlet beams 35 are symmetrically mounted on the top outer peripheral wall of the central rotating rod 31. Each water inlet beam 35 is angularly offset from the extension beam 32. The water-absorbing blades... The upper and lower surfaces of the blade 33 are connected to the staggered water inlet beam 35 and extension beam 32, respectively, so that the water absorption blade 33 is twisted and offset around the central rotating rod 31. When the water inlet beam 35 and extension beam 32 rotate axially synchronously with the central rotating rod 31, the twisted and offset water absorption blade 33 rotates together with the water inlet beam 35 and extension beam 32 and has a fan blade function, thereby blowing the air entering the inner cavity of the cylindrical shell 1 from top to bottom to the air outlet 102 and exhausting it to the outside of the freezer.

[0020] The upper surface of the water inlet beam 35 is provided with several guide pipes 36. The upper and lower ends of the guide pipes 36 are connected to the liquid collection chamber 201 and the lower surface of the water inlet beam 35, respectively. This allows the defrosting water flowing into the liquid collection chamber 201 to flow into the water inlet beam 35 through the guide pipes 36 and continue to flow downwards to be absorbed by the water absorption blades 33. The water absorption blades 33 are made of rigid absorbent material. The defrosting water absorbed by the water absorption blades 33 will continue to flow downwards and diffuse under the action of gravity until the entire water absorption blades 33 are wetted. When the water absorption blades 33 are wetted by the defrosting water and rotate with the central rotating rod 31, they can better block the air, thereby improving the blowing effect and making the air flow rate in the inner cavity of the cylindrical shell 1 faster. This makes it easier for the defrosting water diffused in the water absorption blades 33 to evaporate with the high-speed airflow. The defrosting water evaporated into the air is discharged from the freezer with the airflow in the inner cavity of the cylindrical shell 1.

[0021] As a complementary feature, the freezer's refrigeration compartment has an air inlet window to allow air to circulate within the compartment and dissipate heat from the compressor. The rotation of the water-absorbing blades 33 draws the heated air from the refrigeration compartment into the cylindrical shell 1 after absorbing the heat from the compressor's operation, so that the high-temperature, high-velocity airflow can quickly evaporate the defrosting water carried by the water-absorbing blades 33.

[0022] Understandably, the defrosting water entering the collection chamber 201 will first flow from the guide pipe 36 near the central rotating rod 31 to the water-absorbing blade 33. The defrosting water flowing into the water-absorbing blade 33 will diffuse away from the central rotating rod 31 due to centrifugal force when the water-absorbing blade 33 rotates. When the speed of the defrosting water flowing into the collection chamber 201 is greater than the speed of the flow of the guide pipe 36 near the central rotating rod 31, the liquid level of the defrosting water in the collection chamber 201 will rise until it covers the guide pipe 36 that is far from the central rotating rod 31, and is guided down by more guide pipes 36. The defrosting water that flows to the water-absorbing blade 33 but is not evaporated in time will be thrown by the water-absorbing blade 33 to the inner wall of the cylindrical shell 1 and flow down the inner wall of the cylindrical shell 1 to the recovery bottom plate 4.

[0023] The recycling base plate 4 has a recycling tank 401. The drive motor 34 is installed at the center of the recycling tank 401. The defrosting water thrown out by the water-absorbing blades 33 is also collected by the recycling tank 401. The waterproof shell of the drive motor 34 can be soaked by the defrosting water flowing into the recycling tank 401, so that the heat generated by its operation can be absorbed by the defrosting water in the recycling tank 401. This allows the drive motor 34 to be effectively cooled while the defrosting water in the recycling tank 401 is heated and evaporated quickly. The air outlet 102 is opened above the recycling tank 401 so that the airflow in the cylindrical shell 1 will first flow over the surface of the recycling tank 401 when it is discharged from the freezer through the air outlet 102, thereby accelerating the evaporation of the defrosting water collected in the recycling tank 401.
