Description

Technical Field

[0001] This utility model relates to the field of evaporator fin defrosting technology, and more specifically to a cold storage defrosting device based on an air jet device. Background Technology

[0002] Cold storage facilities often accumulate frost when storing food, medicine, and other sensitive goods, affecting operational efficiency and cargo quality. Therefore, cold storage defrosting services have become an essential service for cold chain logistics companies. Regular and scientific defrosting operations are crucial for maintaining the normal operation of cold storage facilities, reducing energy consumption, and extending equipment lifespan.

[0003] With the development of modern cold storage, some solutions have been developed to address the problem of excessive frost buildup in cold storage. For example, in a cold storage defrosting device disclosed in utility model patent CN202928255U, a flushing pipe connected to a water supply pipe is installed above the evaporator inside the cold storage. Although the temperature of the flushing water can be easily adjusted according to the defrosting needs, there is a problem that water defrosting cannot completely remove frost. For instance, after water defrosting, too many water droplets remain on the fins, causing them to freeze directly during the next refrigeration cycle, affecting collection. In a novel cold storage defrosting device disclosed in utility model patent CN219531340U, a collection box and a receiving box are included. The receiving box has a frost scraper that can be moved up and down. Although the collection box and receiving box can collect the frost scraped off the inner wall of the cold storage during defrosting, preventing the frost from falling to the ground, it may not be able to scrape off all the frost, affecting the defrosting efficiency of the device. Utility Model Content

[0004] In view of this, the present invention provides a cold storage defrosting device based on an air jet device, which can remove the remaining water droplets on the evaporator fins and avoid affecting the operation of the cold storage.

[0005] To achieve the above objectives, the present invention provides a cold storage defrosting device based on an air jet device, which is applied to the evaporator in a cold storage. The air jet device includes an air tank, a compressor connected to the air inlet end of the air tank, and several gas nozzles connected to the air outlet end of the air tank. An air pump is provided between the gas nozzles and the air tank. The air tank is located in a water storage tank, and the gas nozzles are arranged facing the fins of the evaporator.

[0006] Preferably, the cold storage defrosting equipment further includes a water spraying device, which includes a water pump connected to a water storage tank, and a water spraying pipe connected to one end of the water pump's outlet. The water outlet of the water spraying pipe is positioned towards the fins of the evaporator.

[0007] Preferably, a water collection tray is provided below the evaporator, and the water collection tray is connected to a water storage tank.

[0008] Preferably, a first valve is provided between the air compressor and the air storage tank.

[0009] Preferably, a second valve is provided between the air pump and the gas nozzle.

[0010] Preferably, the water spray pipe is equipped with a third valve.

[0011] As can be seen from the above technical solution, compared with the prior art, the cold storage defrosting equipment based on a jet device disclosed in this utility model can store a certain amount of high-temperature water in the water tank. First, compressed air is introduced into the air storage tank by a compressor. The gas is then heated by water, resulting in high-pressure, high-temperature, and high-speed gas drawn out by the air pump. A row of nozzles in the evaporator sprays air in a specific direction onto the fins of the evaporator, ensuring that water droplets are collected in the water collection tray during defrosting and drying the fins, thus preventing any impact on the overall defrosting efficiency. Furthermore, this utility model also has the following advantages:

[0012] 1. Rapid defrosting: When the frost in the cold storage is not thick, the jet device can quickly remove the frost from the evaporator fins, which helps to maintain the efficient operation of the overall equipment;

[0013] 2. Energy saving: Defrosting is achieved by compressing and heating air, reducing the number of electric heating elements and saving energy consumption to a certain extent;

[0014] 3. Improved efficiency: Jet defrosting can thoroughly remove frost and water droplets from the evaporator fins, helping to maintain the optimal performance of key components such as heat exchangers and ensuring that the operating efficiency of the unit is not affected.

[0019] 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. The following description of an exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] Please see the appendix Figure 1-2 This invention discloses a cold storage defrosting device based on an air jet device.

[0021] The cold storage defrosting device based on the jet device provided by this utility model is applied to the evaporator 6 in the cold storage and can remove the remaining water droplets on the fins of the evaporator 6 to avoid affecting the operation of the cold storage.

[0022] like Figure 1 As shown, the jetting device includes a compressor 1, a gas storage tank 2, and several gas nozzles 5.

[0023] The compressor 1 is connected to the inlet of the gas storage tank 2, the gas nozzle 5 is connected to the outlet of the gas storage tank 2, the gas pump 4 is provided between the gas nozzle 5 and the gas storage tank 2, the gas storage tank 2 is located in the water storage tank 3, and the gas nozzle 5 is positioned towards the fins of the evaporator 6.

[0024] In use, air is first compressed into the air storage tank 2 by the air compressor 1. A certain amount of high-temperature water is stored in the water storage tank 3. By heating the water in the air storage tank 2, the high-temperature water in the water storage tank 3 exchanges heat with the gas in the air storage tank 2, so that the gas in the air storage tank 2 reaches a certain temperature. The gas nozzle 5 in the evaporator 6 is directed towards the fins. After the air pump 4 is turned on, high-speed, high-temperature gas is sprayed out through the gas nozzle 5 to heat and defrost the frost on the surface of the fins.

[0025] To further optimize the above technical solution, the cold storage defrosting equipment also includes a water spray device, such as... Figure 2 As shown, the water spraying device includes a water pump 8 connected to the water storage tank 3, and a water spraying pipe 9 connected to one end of the water outlet of the water pump 8. The water outlet of the water spraying pipe 9 is arranged towards the fins of the evaporator 6.

[0026] When in use, first turn on the water pump 8 to circulate the heated water in the water tank 3 to the thick frost in the evaporator 6, washing away the thick and hard frost and turning a large amount of frost into liquid water droplets.

[0027] It should be noted that a water collection tray 7 is provided below the evaporator 6. The water collection tray 7 is connected to the water storage tank 3. Water droplets formed after the water spray pipe 9 washes away the frost fall into the water collection tray 7. Water droplets formed when the jet device heats and defrosts the frost on the surface of the fins also fall into the water collection tray 7. Then, the water flows through the pipeline to the water storage tank 3 for recycling.

[0028] It should be noted that the cold storage defrosting equipment includes several valves for controlling the flow of gas and water. Specifically, a first valve is provided between the air compressor 1 and the air storage tank 2, a second valve is provided between the air pump 4 and the gas nozzle 5, and a third valve is provided on the water spray pipe 9.

[0029] The working principle of the cold storage defrosting equipment provided by this utility model is as follows:

[0030] In the cold storage, when the amount of frost on the surface of the evaporator 6 is not large, defrosting can be performed directly by the jetting device. Air is compressed into the air storage tank 2 by the compressor 1, and the gas inside the air storage tank 2 is heated by water to reach a certain temperature. At this time, the gas nozzle 5 in the evaporator 6 is facing the fins, and the air pump 4 is turned on to spray high-speed, high-temperature gas through the gas nozzle 5 for heating and defrosting.

[0031] When the frost in the cold storage is thick enough that the air jet device alone cannot achieve a good effect, the water pump 8 is first turned on to circulate the heated water in the water tank 3 to the thick frost in the evaporator 6, washing away the thick and hard frost. When a large amount of frost turns into water droplets, the air is then compressed into the air tank 2 by the air compressor 1. The air tank 2 is heated by water to bring the gas in the air tank 2 to a certain temperature. The gas nozzle 5 in the evaporator 6 is then pointed at the fins, and the air pump 4 is turned on to spray high-speed, high-temperature gas through the gas nozzle 5 to spray the small water droplets still remaining on the fins in the evaporator 6, ensuring that there is no frost or water droplets on the fins, and maximizing the efficiency of circulation and other components.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
