[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] 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 of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a defrosting device for an air conditioner, comprising a shell 1, a rear cover 2 is arranged on one side of the outer wall of the shell 1, a square hole 3 is opened on the outer wall of the rear cover 2, an evaporator 4 is arranged between the inner walls of the square hole 3, two square holes 5 are opened on the outer wall of the rear cover 2, a square groove 6 is opened on one side of the outer wall of the shell 1, a hole 7 is opened on the outer wall of the shell 1, a threaded rod 8 is movably inserted into the inner wall of the hole 7, a motor 9 is arranged on one side of the outer wall of the threaded rod 8, a movable slide 10 is threadedly connected to the outer wall of the threaded rod 8, a connecting plate 11 is fixedly installed on one side of the outer wall of the movable slide 10, a scraper 12 is fixedly installed on one side of the outer wall of the connecting plate 11, a hole 13 is opened on the outer wall of the shell 1, a guide rod 14 is fixedly inserted into the inner wall of the hole 13, and a movable slide 15 is movably sleeved on the outer wall of the guide rod 14.

[0024] The effect achieved by the entire embodiment 1 is that, first, the scraper 12 passes through the square hole 25, and the motor 9 is connected to the threaded rod 8, the threaded rod 8 is threadedly connected to the movable slide 10, and the movable slide 2 15 is connected to the guide rod 14, and the movable slide 10 is connected to the movable slide 2 15 through the scraper 12. The operation of the motor 9 drives the threaded rod 8 to rotate, thereby driving the movable slide 10 to move, and finally drives the scraper 12 to move, which can adapt to various complex frosting conditions. Whether it is a light frost layer or a thick ice layer, the scraper 12 can effectively scrape it off, which enables the air conditioner to maintain stable operation under various severe weather conditions. At the same time, the guide rod 14 can provide support for the scraper 12, reduce the direct friction and wear of the scraper 12 during the movement process, which helps to extend the service life of the scraper 12 and reduce the frequency of replacement and maintenance.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, a second square groove 16 is provided on one side of the outer wall of the shell 1, a third square groove 17 is provided on one side of the outer wall of the shell 1, a third hole 18 is provided at the bottom of the inner wall of the second square groove 16, a temperature sensor 19 is arranged between the inner walls of the second square groove 16, an electric wire 20 is arranged at the output end of the temperature sensor 19, and a controller 21 is arranged between the inner walls of the third square groove 17.

[0026] The effect achieved by the entire embodiment 2 is that when the device is in normal use, first, the temperature sensor 19 is connected to the controller 21 through the wire 20. The temperature sensor 19 can more accurately monitor the temperature of the evaporator 4, so as to more accurately determine whether it is necessary to start the defrost operation, which helps to improve the efficiency and accuracy of defrosting. Secondly, if defrosting is determined, a signal is transmitted to the controller 21 to control the motor 9 to run and defrost the device.

[0027] Among them, the evaporator 4, the motor 9, the temperature sensor 19 and the controller 21 are all prior arts, and their components and operating principles are all public arts, and no further explanation is given here.

[0028] Working principle: first, when the device is in normal use, the evaporator 4 is linearly connected with the controller 21. When the air conditioner is running, frost will form on the outer wall of the evaporator 4. Secondly, a threaded rod 8 is movably inserted into the inner wall of the hole 7. A motor 9 is arranged on one side of the outer wall of the threaded rod 8. A movable slide 10 is threadedly connected to the outer wall of the threaded rod 8. At the same time, a guide rod 14 is fixedly inserted into the inner wall of the hole 2 13. A movable slide 2 15 is movably sleeved on the outer wall of the guide rod 14. A connecting plate 11 is fixedly installed on one side of the outer wall of the movable slide 10. One side of the outer wall of the connecting plate 11 is fixedly connected to the movable slide 2 15. At this time, the motor 9 operates normally, which can drive the threaded rod 8 to rotate, thereby driving the movable slide 10 to move. By adjusting the rotation speed and angle of the threaded rod 8, the moving distance and speed of the scraper 12 on the surface of the evaporator 4 can be accurately controlled, thereby ensuring that the frost layer is evenly and thoroughly scraped off. At the same time, the movable slide 2 15 follows the movable slide 10 in The scraper 12 moves on the guide rod 14 to drive the scraper 12 to move. The existence of the guide rod 14 enhances the stability of the movement of the scraper 12. During the defrosting process, the scraper 12 may encounter frost layers or obstacles of different thicknesses. The guide rod 14 can ensure that the scraper 12 remains stable during the movement to avoid damage to the evaporator 4 due to bumps or deviations. The outer wall of the rear cover 2 is provided with two square holes 25. The scraper 12 is arranged on the outer wall through the square holes 25 and contacts the outer wall of the evaporator 4. Finally, the movement of the scraper 12 scrapes off the frost on the outer wall of the evaporator 4. The scraper 12 can directly contact the frosted surface and quickly scrape off the frost layer by physical means. This method is more direct and efficient than relying on temperature rise to melt the frost layer, which can significantly shorten the defrosting time and improve the working efficiency of the air conditioner. At the same time, the temperature sensor 19 can monitor the temperature of the air conditioner outdoor unit in real time and then transmit it to the controller 21, which controls the operation of the motor 9.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. 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 and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
