[0002] Elevator air conditioning refers to the air conditioning system installed inside an elevator to regulate the temperature and humidity inside the elevator car, thereby improving passenger comfort. This system is typically integrated with the building's overall intelligent control system to achieve energy conservation and intelligent management. In modern buildings, elevator air conditioning has become an important component in ensuring the comfort of public spaces, especially in high-rise buildings where its role is even more significant. Furthermore, with technological advancements, elevator air conditioning is gradually evolving towards greater efficiency and environmental friendliness, for example, through intelligent control to achieve energy conservation and emission reduction.

[0003] Elevator air conditioning anti-frost devices primarily delay or prevent frost formation by optimizing surface structure and material properties. For example, employing a hydrophobic surface design can effectively reduce frost formation on condensate in low-temperature environments, thereby protecting equipment and improving energy efficiency. Furthermore, some devices incorporate thermal insulation technology to reduce the temperature difference between the pipes and the external environment, preventing frost formation caused by sudden temperature drops. These technologies work together to ensure the stability and efficiency of the air conditioning system during operation.

[0012] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The replacement mechanism includes a plug-in assembly and a fixing assembly. The plug-in assembly includes a housing 19, which is fixedly connected to the outside of the filter chamber 3. The housing 19 protects the internal parts from damage. A pin 20 is slidably connected inside the housing 19. A spring 21 is sleeved on the outside of the pin 20. The elasticity of the spring 21 allows the pin 20 to quickly return to its original position. A limit plate 22 is fixedly connected to the outside of the pin 20 to prevent the pin 20 from being ejected due to excessive elasticity of the spring 21. The fixing assembly includes a filter plate 23, which is slidably connected to the inside of the filter chamber 3. The filter plate 23 filters the melted water and impurities in the condensate. A hole 24 is opened in the middle of the filter plate 23. The pin 20 is engaged with the hole 24. By inserting the pin 20 into the hole 24, the filter plate 23 can be tightly fixed inside the filter chamber 3. The sealing mechanism includes a transmission assembly and a closing assembly. The transmission assembly includes a protective shell 5, which is fixedly connected to the outside of the housing 1. The protective shell 5 protects the internal parts from damage. Two insert blocks 27 are slidably connected in the middle of the shell 5. A partition 29 is fixedly connected inside the shell 5 to prevent the springs 28 from shifting. Springs 28 are provided between the two insert blocks 27 and the partition 29. The elasticity of the springs 28 allows the insert blocks 27 to quickly return to their original position. A crossbar 16 is fixedly connected inside the shell 5 to assist the movement of the insert blocks 27, allowing them to move stably. The two insert blocks 27 are slidably connected to the outside of the crossbar 16. The closing assembly includes a cover plate 2.

The filter plate 23 is fixedly connected to the outside of the slide plate 23. The slide block 25 is slidably connected to the inside of the slide groove 26. The slide block 25 slides in the slide groove 26, which facilitates the disassembly and installation of the filter plate 23.

[0013] Working principle: First, when the evaporator 7 is frosted, the hot air blower 17 is started, which will deliver hot air to the spray bar 8. At this time, the motor 10 is started, which will drive the worm gear 11 to rotate. The rotation of the worm gear 11 will drive the worm wheel 12 to rotate, and the rotating rod 13 connected to the worm wheel 12 will rotate together. Therefore, the connecting rod 14 will rotate, which will adjust the angle of the spray bar 8. The rotation of the spray bar 8 can heat the evaporator 7 inside the shell 1 and can fully and evenly cover the evaporator 7, so that the frost on the evaporator 7 is melted into water and flows away from the groove 18.

[0014] Secondly, when condensate flows into the filter chamber 3, the filter plate 23 can filter the impurities in the condensate to prevent clogging of the pipe. After long-term use, the filter plate 23 needs to be replaced. At this time, by pulling the pin 20, the pin 20 will move the limiting plate 22 together. The movement of the limiting plate 22 will squeeze the second spring 28. When the pin 20 is completely pulled out of the insertion hole 24, the filter plate 23 can be pulled out for cleaning and then put back into the filter chamber 3. Release the hand that pulled the pin 20. Due to the elasticity of the second spring 28, the pin 20 will immediately return to the center and firmly fix the filter plate 23.

[0015] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
