Description

Technical Field

[0001] The utility model belongs to the technical field of air coolers, and in particular relates to an anti-air cross-contamination drainage device for air coolers. Background Art

[0002] At present, in the existing refrigeration industry, the drain pipe of the air cooler used in the cold storage will be led out of the storage, and a U-shaped water return bend needs to be added to the drain pipe to prevent the hot air outside the storage from entering the cold storage, increasing the frost amount of the fan and the heat load of the cold storage; when the air cooler in the cold storage performs defrosting operation, a water seal will be formed at the U-shaped bend of the water return bend, but when using such a U-shaped water return bend, it will be affected by the ambient temperature. When the ambient temperature is below 0℃, the U-shaped bend will freeze, which will cause the water generated by the air cooler inside the cold storage to be unable to be discharged, thereby affecting the heat exchange effect of the fan. At the same time, if the ice in the pipe is serious, it will also cause damage to the motor and overflow of the water pan of the air cooler. In addition, the port of the drain pipe lacks an anti-gas cross-talk mechanism, so there is a possibility of gas cross-talk between the air outside the storage and the air cooler, affecting the use effect of the air cooler and failing to effectively meet the use requirements. For this reason, we provide an anti-gas cross-talk drainage device for an air cooler. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Examples, such as Figures 2 to 5As shown, an anti-cross-flow drainage device for an air cooler 2 includes an anti-cross-flow drainage device body 4, a drainage pipe 1 is arranged above the anti-cross-flow drainage device body 4, the upper end of the drainage pipe 1 is connected to the air cooler 2, and the air cooler 2 is placed above the cold storage 3. Among them, for the establishment of the above-mentioned devices and equipment, they are all existing mature technologies, and the details are not repeated here. This embodiment aims to solve the problem of cross-flow and drainage inconvenience of the drainage pipe 1 of the air cooler 2. Specifically, the anti-cross-flow drainage device body 4 includes a connecting sleeve 5, and a connecting pipe 6 with a hollow T-shaped design is arranged below the connecting sleeve 5. A through hole 61 is opened above the connecting pipe 6, and an adaptive opening and closing mechanism is arranged in the connecting pipe 6. The adaptive opening and closing mechanism includes an ear seat 7, a rotating rod 8 is arranged between the two ear seats 7, a rotating plate 9 is arranged on the outer periphery of the rotating rod 8, and a sealing head 10 is arranged on one side of the rotating plate 9. For the rotating plate 9 and the sealing head 10 established, the material can be selected from low-temperature resistant plastic material. When the water level is low, the plugging head 10 is reset under the action of the torsion spring 11, and the anti-gas function is continued to be performed, thereby ensuring the performance of the device.

[0020] After the water in the water pipe 1 is drained out, the water in the water pipe 1 will be automatically drained out of the water pipe 1 and ...

[0021] In order to ensure the effective collection of water and realize self-flow, the connecting sleeve 5 includes a water receiving pipe 51 for connecting to the drain pipe 1, wherein the water receiving pipe 51 can be screwed together with the drain pipe 1 by means of threaded connection, or the drain pipe 1 can be sleeved on the outer periphery of the water receiving pipe 51 to ensure the tightness of the connection between the two. A guide pipe 52 with a hollow conical table design is provided in the water receiving pipe 51 and is connected with the through hole 61. The guide pipe 52 is used to receive the water discharged from the drain pipe 1 and is concentrated to the through hole 61 when the guide pipe 52 is closed. It acts on the sealing head 10 and uses the gravity of the water to press the sealing head 10 to realize rotation. In this way, water can flow out from the anti-cross-flow drainage device to ensure usage requirements.

[0022] In order to further improve the rationality of the device, a key-shaped drain groove 521 is provided on the inner wall of the guide pipe 52. The drain groove 521 can guide the water falling through the drain pipe 1 so that it can fully fall above the sealing head 10 and open with the help of the water's own gravity, thereby realizing self-flow to meet usage requirements.

[0023] In order to ensure the drainage of water in the drain pipe 1 and reduce the possibility of external air entering, the lower end of the connecting pipe 6 is designed to be closed. This design not only ensures the smooth drainage of water, but also the closed design from the inside to the outside reduces the possibility of cross-contamination between external air and the air cooler 2, thereby ensuring the use effect. Of course, this design can also be set up in a duckbill shape, which can not only ensure the smooth drainage of water, but also reduce the area entered by external air to ensure practicality.

[0024] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
