Description

Technical Field

[0001] This utility model relates to the field of air curtain cabinets, and in particular to a top drainage component in an air curtain cabinet. Background Technology

[0002] Air curtain cabinets, also known as air screens or airflow barriers, are mainly used in commercial spaces to insulate against outside hot air by preventing cold air from escaping. Condensation is generated during the operation of air curtain cabinets, and the methods for handling this condensation are generally as follows:

[0003] 1. Direct discharge: Some air curtain cabinets may discharge condensate directly to the ground or through pipes to the sewer. This method is simple and easy to implement, but it may cause the ground to be slippery, increasing safety risks, especially in areas with high traffic.

[0004] 2. Built-in water tank: Some models of air curtain cabinets are equipped with a small internal water tank to collect condensate. The tank needs to be emptied manually when full. While this avoids a wet floor, forgetting to empty the tank regularly can lead to overflow and increase maintenance workload.

[0005] 3. Gravity drainage method: By installing a drainage pipe at the bottom of the air curtain cabinet, condensate is naturally drained into a floor drain or other drainage system by gravity. This method does not require an additional power source and is relatively low in cost; however, its efficiency is greatly limited by the installation location and it is not suitable for all sites.

[0006] In addition, some shops in commercial spaces are converted stores without drainage systems, and installing new drainage pipe systems would be extremely costly. Furthermore, some shops are located in basements without natural drainage, making conventional cabinet types unusable or prohibitively expensive.

[0007] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0008] The purpose of this invention is to provide a top-drainage component for an air curtain cabinet to solve the problems existing in the prior art.

[0009] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0010] A top-drainage component for an air curtain cabinet includes an air curtain cabinet and a top-drainage component installed inside the air curtain cabinet.

[0011] The top-drainage component includes a water storage tank, a water pumping pipe on the water storage tank, a first water pump on the water pumping pipe, and the water inlet of the water pumping pipe extends to the bottom of the air curtain cabinet. A first water level switch is installed at the bottom of the air curtain cabinet. The first water level switch is used to control the first water pump to transport the condensate at the bottom of the air curtain cabinet to the water storage tank through the water pumping pipe.

[0012] The water storage tank is equipped with a second water level switch and a second water pump. An upper drainage pipe is installed on the top of the water storage tank. The inlet end of the upper drainage pipe is located inside the water storage tank, and the outlet end of the upper drainage pipe is connected to the drainage pipe of the air conditioning system. A one-way valve and a pagoda ball valve are installed on the upper drainage pipe. The second water level switch is used to control the second water pump to transport the condensate in the water storage tank to the drainage pipe of the air conditioning system through the upper drainage pipe.

[0013] Furthermore, the water storage tank includes a tank body and a water tank cover located on top of the tank body; the water pumping pipe is a PVC hose, with the inlet end of the PVC hose located at the bottom of the air curtain cabinet and the outlet end of the PVC hose extending into the interior of the tank body through a through hole on the water tank cover.

[0014] Furthermore, the bottom surface of the water tank cover of the water storage tank is provided with a water pump fixing component, which is fixed to the water tank cover with screws, and the second water pump is installed and fixed through the water pump fixing component.

[0015] Furthermore, the water storage tank is mounted on a water tank fixing component, which is fixed to the lower left corner of the air curtain cabinet with screws.

[0016] Furthermore, the first water pump is installed on the water surface of the air curtain cabinet via a suction cup, and a filter screen is fitted around the outside of the first water pump.

[0017] Furthermore, the first water level switch is fastened to the rear side of the boat bottom of the air curtain cabinet with screws, and the signal output terminal of the first water level switch is connected to the first water pump and the audible and visual alarm respectively; the second water level switch is installed on the water tank cover through a sensor fixing plate, and the signal output terminal of the second water level switch is connected to the second water pump.

[0018] Furthermore, each end of the upper drainage pipe is provided with an elastic quick-release clamp. Both the water pumping pipe and the upper drainage pipe extend into the tank body through the through hole on the water tank cover, and a snap-on protective sleeve is provided in the through hole.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. High adaptability: Top-drainage components do not rely on gravity to guide water flow; instead, a water pump discharges condensate from the drain pipe leading to the elevated air conditioning system. This allows the air curtain unit to be installed more flexibly in different locations, such as uneven ground or areas without a suitable slope, without worrying about drainage issues.

[0021] 2. Reduced floor space: Due to the top drainage design, the drainage pipes can be arranged more compactly and concealed without affecting the normal use of the equipment, thus saving valuable commercial space, which is especially important in retail environments where every inch of space is precious.

[0022] 3. Avoid ground pollution and safety risks: Compared to the slippery floor that may be caused by natural drainage, top drainage can effectively prevent condensation from dripping directly onto the ground, reducing the risk of customers slipping and keeping the business area clean and tidy.

[0023] 4. Reduced noise interference: The top-drainage component uses a silent brushless DC water pump, which reduces the impact on the surrounding environment while ensuring drainage efficiency, providing customers with a quieter and more comfortable shopping experience.

[0024] 5. Compliance with hygiene standards: For the food retail industry, ensuring all facilities meet stringent hygiene requirements is crucial. Top-drainage systems offer better control over water flow and are less prone to secondary contamination, making them easier to comply with relevant regulations.

[0025] In conclusion, the use of top-drainage components in air curtain cabinets not only improves the functionality and applicability of the equipment, but also enhances the user experience and service quality to a certain extent. Attached Figure Description
