Description

Technical Field

[0001] This utility model relates to the field of display cabinet drainage technology, and more specifically to a drainage device for a food preservation display cabinet. Background Technology

[0002] Food display cases play a crucial role in modern commercial environments. They not only effectively extend the shelf life of food, maintaining its quality and taste, but also offer numerous advantages such as precise temperature control, energy efficiency, excellent display effects, and safety and reliability. During operation, food display cases are prone to condensation due to the moisture inherent in the food itself and the temperature difference between the inside and outside of the case. A drainage system promptly removes this condensed moisture, preventing moisture buildup inside the case and keeping it clean and tidy. This not only helps attract customer attention but also enhances the overall image of the store.

[0003] As shown in the prior art disclosed in CN211354728U, although this prior art uses a frame and exhaust vents, with the frame's interior being a cavity allowing cold air to escape through the vents to cool the upper part of the frame, and a vertical rail with adjusting bolts to move the frame along the rails to control the distance between the entire frame and the inner wall of the storage compartment for water cooling, the overall design allows for diverse cooling and preservation methods, enabling different cooling and preservation methods for different foods, making it more practical. However, this prior art is prone to clogging by food residue during drainage, affecting drainage efficiency, and the odor from the mixed food residue can permeate the inside of the cabinet, thus affecting the customer's experience when selecting food. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a drainage device for a food preservation display cabinet. A fan drives a spiral blade on a movable shaft to rotate, achieving orderly transport of food residue and preventing blockage of the drainage tube. Simultaneously, the fan drives airflow within the cabinet cavity, allowing the air to be discharged through air holes on the drainage tube and the sealing tube. This prevents the odor from food residue mixing and affecting the customer's food selection experience, thereby improving the practicality and functional versatility of this utility model and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a drainage device for a food preservation display cabinet, comprising a cabinet cavity located at the top of the cabinet for storing food, and a drainage component located at the rear of the cabinet for discharging dirty water and residue.

[0006] The drainage component includes a drain tube installed at the rear bottom of the cabinet, with the front end of the drain tube connected to the cabinet cavity. A discharge port is provided at the bottom of the rear end of the drain tube. A sealing tube is installed at the rear end of the drain tube. A fan is installed inside the sealing tube, and a movable shaft is installed at the front end of the output shaft of the fan. The front end of the movable shaft extends into the interior of the drain tube, and a spiral blade is installed on the outside of the front end of the movable shaft.

[0007] In a preferred embodiment, multiple air holes are provided on the outer rear end of the diversion tube and the outer rear end of the packaging tube. The multiple air holes are evenly spaced apart. By setting the air holes, the air inside the cabinet can be guided to circulate, thereby achieving the effect of expelling odors from the cabinet and preventing odors from affecting the customer's experience of selecting food.

[0008] In a preferred embodiment, the bottom of the rear end of the drain tube is provided with a deformable sealing plug, and the top of the sealing plug extends into the discharge port. By engaging with the discharge port, the sealing plug can block the discharge port and prevent debris from entering the cabinet through the drain tube and causing pollution.

[0009] In a preferred embodiment, a fixing frame is installed at the top rear end of the drainage tube. Both ends of the fixing frame are equipped with fixing plates that are movably connected by a rotating shaft. Fixing holes are provided on the outside of the fixing plates. The movable connection between the fixing plates and the fixing frame allows the user to operate the sealing plug for rotation and adjustment, thereby achieving convenient operation of the sealing plug.

[0010] In a preferred embodiment, each fixed plate has a hollow column at its bottom, a spring inside the hollow column, a movable plate at the top of the spring, a movable column at the bottom of the movable plate, the spring being sleeved on the outside of the movable column, and the bottom end of the movable column passing through the hollow column and fixed together with one side of the bottom end of the sealing plug. By means of the elasticity of the spring, it is easy to operate the sealing plug to separate or contact with the discharge port, thereby ensuring the sealing effect of the sealing plug on the discharge port.

[0011] In a preferred embodiment, a mounting post is installed at the top of the hollow column. The top of the mounting post passes through the fixing hole and extends to the top of the fixing plate. A mounting nut is externally threaded to the top of the mounting post. The mounting nut is threaded to the mounting post, and the sealing plug can be easily replaced when the mounting nut is rotated to separate from the mounting post.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By driving the spiral blades on the movable shaft to rotate by the fan, food residue is transported in an orderly manner, thus avoiding blockage of the diversion tube. At the same time, the fan drives the air flow in the cabinet cavity, so that the air in the cabinet cavity is discharged through the air holes on the diversion tube and the air holes on the sealing tube, thus avoiding the odor of food residue mixed together affecting the customer's food selection experience, thereby improving the practicality and functional diversity of this utility model.

[0014] 2. The elasticity of the spring facilitates the separation of the sealing plug from the discharge port by pulling it down. Then, the spring's rebound force drives the sealing plug to fit tightly against the discharge port, thereby improving the user's convenience in operating the sealing plug. At the same time, the connection between the moving column and the sealing plug can limit the sealing plug and prevent it from falling off and being lost.

[0015] 3. The installation nut is threadedly connected to the installation column, allowing users to easily rotate the installation nut to separate it from the installation column. This facilitates the convenient disassembly and replacement of the hollow column and sealing plug, preventing wear on the sealing plug from affecting the sealing effect on the discharge port and thus ensuring the sealing effect of the discharge port.

Detailed Implementation

[0022] 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.

[0023] Refer to the instruction manual appendix Figure 1-5 This utility model provides a drainage device for a food preservation display cabinet, including a cabinet cavity 2 located at the top of the cabinet body 1 for storing food, and a drainage component for draining dirty water and residue on the rear side of the cabinet body 1.

[0024] To ensure smooth discharge of wastewater and prevent residue buildup that could cause blockages, such as Figure 3 and 4 As shown, the drainage component includes a drainage tube 3 installed on the rear side of the bottom of the cabinet 1, and the front end of the drainage tube 3 is connected to the cabinet cavity 2. A discharge port 4 is opened at the bottom of the rear end of the drainage tube 3. A sealing tube 5 is installed at the rear end of the drainage tube 3. A fan 6 is installed inside the sealing tube 5, and a movable shaft 7 is installed at the front end of the output shaft of the fan 6. The front end of the movable shaft 7 extends into the interior of the drainage tube 3. A spiral blade 8 is installed on the outside of the front end of the movable shaft 7. Multiple air holes 9 are opened on the outside of the rear end of the drainage tube 3 and the outside of the rear end of the sealing tube 5, and the multiple air holes 9 are evenly spaced.

[0025] During use, the moisture on the food and inside the cabinet 1 is collected in the cabinet cavity 2, and then the dirty water is discharged through the drain tube 3. In order to prevent food residue falling into the cabinet cavity 2 from clogging the drain tube 3, the fan 6 is started to drive the movable shaft 7 to rotate. The movable shaft 7 then guides the food residue to the discharge port 4 through the spiral blade 8, thus avoiding the clogging of the drain tube 3.

[0026] While the fan 6 drives the movable shaft 7 to rotate, it also drives the air in the cabinet cavity 2 to flow, so that the air in the cabinet cavity 2 is discharged through the air hole 9 on the drainage tube 3 and the air hole 9 on the sealing tube 5. This can prevent the odor of food residue mixed together from affecting the customer's experience of selecting food, and thus effectively improve the practicality and functional diversity of this utility model.

[0027] After drainage is completed, to prevent other impurities from entering the cabinet cavity 2 through the drainage tube 3, the discharge port 4 needs to be sealed, such as... Figure 3-5 As shown, the bottom of the rear end of the diversion tube 3 is provided with a deformable sealing plug 10, and the top of the sealing plug 10 extends into the discharge port 4. Through the deformable sealing plug 10, the user can snap the sealing plug 10 into the discharge port 4, thereby sealing the discharge port 4 and preventing impurities from entering the cabinet cavity 2 and causing pollution.

[0028] To improve the ease of operation of the sealing plug 10, and to prevent the sealing plug 10 from falling off and being lost, such as Figure 3 and 5As shown, a fixing frame 11 is installed at the top rear end of the drainage tube 3. Fixing plates 12 are installed at both ends of the fixing frame 11 and are movably connected by a rotating shaft. Fixing holes 13 are opened on the outside of the fixing plates 12. A hollow column 14 is provided at the bottom of each fixing plate 12. A spring 15 is provided inside the hollow column 14. A movable plate 16 is provided at the top of the spring 15. A movable column 17 is installed at the bottom of the movable plate 16. The spring 15 is sleeved on the outside of the movable column 17. The bottom end of the movable column 17 passes through the hollow column 14 and is fixed together with one side of the bottom end of the sealing plug 10.

[0029] In use, the user pulls down the sealing plug 10 and moves the moving plate 16 connected to the moving column 17 downward. At the same time, the moving plate 16 moves the spring 15 downward. Since the fixed plate 12 is movably connected to the fixed frame 11 through the rotating shaft, the user can pull the sealing plug 10 outward and rotate it around the rotating shaft on the fixed frame 11. This makes the discharge port 4 unobstructed and facilitates drainage. At the same time, the sealing plug 10 is rotated and stored at the top of the drain cylinder 3 to prevent the sealing plug 10 from falling off and being lost.

[0030] After the drainage is finished, the user operates the sealing plug 10 to rotate inward to the discharge port 4. Then, the spring 15 pushes the moving plate 16 upward. The moving plate 16 then pushes the sealing plug 10 upward with the help of the moving column 17, so that the sealing plug 10 is embedded in the discharge port 4 to seal it and prevent external impurities from entering the cabinet 1 through the diversion tube 3 and causing pollution.

[0031] Meanwhile, with prolonged use, the sealing plug 10 may wear down, affecting the sealing effect. In such cases, the sealing plug 10 needs to be replaced. Figure 3 and 5 As shown, a mounting post 18 is installed at the top of the hollow column 14. The top of the mounting post 18 passes through the fixing hole 13 and extends to the top of the fixing plate 12. A mounting nut 19 is externally threaded to the top of the mounting post 18. The user can rotate the mounting nut 19 to separate it from the mounting post 18, so that the mounting post 18 is not restricted in position. This makes it easy for the user to disassemble the hollow column 14 and the sealing plug 10 for replacement, thereby ensuring the sealing effect on the discharge port 4.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
