Description

Technical Field

[0001] This utility model relates to the field of air cooler defrosting technology, and in particular to an air cooler defrosting device. Background Technology

[0002] An evaporative air cooler is an evaporative cooling and ventilation unit that integrates cooling, ventilation, dust prevention, deodorization, and humidification. Icing on cold storage fans is mainly due to the moisture drawn in during operation forming snowflakes or frost within the air ducts. With prolonged use or in low-temperature, high-humidity environments, the accumulated snowflakes or frost increase, leading to icing. Once icing occurs, it is difficult to clean, so defrosting is necessary as soon as frost forms in the air ducts. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where evaporative air coolers are difficult to clean after icing and require timely defrosting. Therefore, this invention proposes an evaporative air cooler defrosting device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a defrosting device for an air cooler, including an outer frame. A lead screw is rotatably mounted inside the outer frame. A lead screw assembly is threaded onto the outer side of the lead screw. A movable seat is fixedly mounted at the lower end of the lead screw assembly. A rotating disk is rotatably mounted on one side of the movable seat. Scrapers are fixedly mounted on the surface of the rotating disk away from the movable seat. Multiple sets of scrapers are arranged in a circular array around the central axis of the rotating disk. A blower nozzle is fixedly mounted on the top of the movable seat. An air supply mechanism is fixedly mounted on the top of the outer frame. The air supply mechanism is connected to the blower nozzle.

[0006] Preferably, the air supply mechanism includes an air supply box, which is fixedly installed on the top of the outer frame. An air inlet is provided on the side wall of the air supply box, and a fan is fixedly installed inside the air supply box. The fan is connected to the air nozzle through a pipe.

[0007] Preferably, a wire mesh is fixedly installed inside the air supply box, the wire mesh is located outside the fan, and a heating coil is fixedly installed at the bottom of the wire mesh.

[0008] Preferably, the surface of the rotating disk away from the movable seat is also fixedly equipped with brush bristles.

[0009] Preferably, the distance between the brush bristle end face and the surface of the rotating disk is greater than the distance between the scraper end face and the surface of the rotating disk.

[0010] Preferably, the lead screw is horizontal in its length direction and parallel to the side of the outer frame.

[0011] Preferably, a base box is fixedly installed at the lower end of the outer frame, and an opening is provided at the upper end of the base box.

[0012] The defrosting device for an air cooler proposed in this utility model has the following advantages: During use, the rotation of the lead screw drives the movable seat to move through the lead screw pair. The movement of the movable seat drives the rotating disk to move, and the movement of the rotating disk drives the scraper to move and rotate. The scraper can scrape off the frost layer on the surface of the air cooler, and the brush can sweep off the remaining frost layer on the surface of the air cooler. The fan blows air downwards through the nozzle, which can blow off the scraper and the remaining frost layer on the surface of the air cooler. The outer frame covers the outside of the air cooler, and when defrosting is needed, it can defrost the surface of the air cooler, and can thoroughly clean the frost layer on the surface of the air cooler. After cleaning, the movable seat can be moved to one side of the air cooler without affecting the normal operation of the air cooler. This can remove the frost layer on the surface of the air cooler's air duct in a timely manner and prevent the frost layer from accumulating and causing ice formation. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1: Refer to Figure 1-4A defrosting device for an air cooler includes an outer frame 1. A lead screw 2 is rotatably mounted inside the outer frame 1. The end of the lead screw 2 is fixedly connected to an external motor, which drives the lead screw 2 to rotate. The lead screw 2 is horizontal in its length direction and parallel to the side of the outer frame 1. A lead screw assembly 3 is threaded onto the outer side of the lead screw 2, and rotation of the lead screw 2 drives the lead screw assembly 3 to move. A movable seat 4 is fixedly mounted at the lower end of the lead screw assembly 3, and rotation of the lead screw assembly 3 drives the movable seat 4 to move. A rotating disk 5 is rotatably mounted on one side of the movable seat 4, and the end of the rotating disk 5 is fixedly connected to an external motor, which drives the rotating disk 5 to rotate. Multiple scraper blocks 51 are fixedly mounted on the surface of the rotating disk 5 away from the movable seat 4, arranged in a circular array around the central axis of the rotating disk 5. Rotation of the rotating disk 5 drives the scraper blocks 51 to rotate, and the rotation of the scraper blocks 51 scrapes off the frost layer on the surface of the outer frame 1. During the rotation of the rotating disk 5, the lead screw 2 drives the movable seat 4 to reciprocate through the lead screw pair 3. The rotating disk 5 and the scraper 51 reciprocate on the surface of the air cooler. The scraper 51 can also move while rotating, which can thoroughly clean the frost layer on the surface of the air cooler. A base box 6 is fixedly installed at the lower end of the outer frame 1. The upper end of the base box 6 is provided with an opening facing the rotating disk 5, so that the scraped-off residual frost can fall into the base box 6.

[0020] A brush bristle 52 is fixedly installed on the surface of the rotating disk 5 away from the movable seat 4. The distance between the end face of the brush bristle 52 and the surface of the rotating disk 5 is greater than the distance between the end face of the scraper 51 and the surface of the rotating disk 5. The brush bristle 52 can fit more closely to the surface and gaps of the outer frame 1, and can brush off residual frost inside the gaps on the surface of the outer frame 1. The scraper 51 can be made of hard sponge. The main function of the scraper 51 is to break up and scrape off the frost layer. However, some residual frost may remain on the surface and in the gaps of the outer frame 1 and cannot be scraped off by the scraper 51. Therefore, the brush bristle 52 is needed to scrape off these residual frost.

[0021] A blower nozzle 8 is fixedly installed on the top of the movable base 4, facing the rotating disk 5 below. An air supply mechanism is fixedly installed on the top of the outer frame 1, and the air supply mechanism is connected to the blower nozzle 8. The air supply mechanism includes an air supply box 7, which is fixedly installed on the top of the outer frame 1. An air inlet 71 is opened on the side wall of the air supply box 7. A fan 74 is fixedly installed inside the air supply box 7. The fan 74 is connected to the blower nozzle 8 through a pipe. When the fan 74 is started, external air will enter the air supply box 7 through the air inlet 71. The air entering the air supply box 7 will be sent out through the pipe and blown out through the blower nozzle 8. The blown air will blow off the scraper 51, brush bristles 52, and residual frost on the surface of the air cooler, further improving the cleaning effect on the surface of the air cooler and its internal crevices.

[0022] An internal mesh screen 72 is fixedly installed inside the air supply box 7. The mesh screen 72 is located outside the fan 74, and a heating coil 73 is fixedly installed at the bottom of the mesh screen 72. The mesh screen 72 is made of iron. By connecting the power supply inside the heating coil 73, the temperature inside the heating coil 73 can be increased, and the temperature inside the heating coil 73 can be transferred to the mesh screen 72. The air entering through the air inlet 71 will be heated by passing through the mesh screen 72, which can increase the internal temperature of the air. When the heating coil 73 is not connected to the power supply, the fan blows out cold air. The power supply inside the heating coil 73 can be turned on or off as needed.

[0023] When the rotating disk 5 drives the scraper 51 to rotate, the scraper 51 cleans the frost layer on the surface of the air cooler. At this time, cold air is needed to blow the scraped-off residual frost downwards, which can remove the frost layer remaining on the surface and inside the gaps of the air cooler. When the residual frost on the surface of the air cooler freezes, the scraper 51 alone cannot remove the frozen frost layer. Therefore, hot air needs to be blown onto the surface of the air cooler to melt and loosen the frozen frost layer, which can then be scraped off by the scraper 51. Whether cold or hot air is blown needs to be adjusted according to the specific situation. Of course, heating with the heating coil 73 will consume more electricity, so the frequency of use can be appropriately reduced.

[0024] Working Principle: During use, the outer frame 1 covers the outside of the evaporative air cooler, with the movable seat 4 located on one side of the cooler, ensuring uninterrupted operation. When frost appears on the surface of the cooler, an external motor is activated, driving the lead screw 2 to rotate. Simultaneously, another external motor is activated, driving the rotating disk 5 to rotate. The rotation of lead screw 2 moves lead screw assembly 3, which in turn moves the movable seat 4, which in turn moves the rotating disk 5. When the rotating disk 5 reaches the outside of the cooler surface, its rotation causes the scraper 51 to rotate, which removes the frost from the cooler surface. The brush 52 can sweep off the frost layer remaining on the surface of the air cooler, and the fan 74 is started. The fan 74 blows air downward through the nozzle 8, which can blow off the scraper 51 and the frost layer remaining on the surface of the air cooler. The blown-off residual frost is collected by the bottom box 6, and the movable seat 4 is moved back and forth by the lead screw 2 to clean the frost layer on the surface of the air cooler. After cleaning, the movable seat 4 can be moved to one side of the air cooler to avoid the movable seat 4 blocking the normal operation of the air cooler. This can remove the frost layer on the surface of the air cooler's air duct in time and prevent the frost layer from accumulating and causing ice formation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
