[0041] First, the present disclosure provides an air conditioner unit cleaning system, as Figures 1 to 4 shown, for simultaneously cleaning a plurality of air conditioner units 101 arranged at intervals along the first direction x. The air conditioner units 101 extend along the second direction y and the third direction z, the second direction y is perpendicular to the first direction x, and the third direction z is perpendicular to the first direction x and the second direction y. The air conditioner unit cleaning system includes:

[0042] A cleaning platform 1, extending along the first direction x;

[0043] A first cleaning liquid delivery pipeline 2, arranged on the cleaning platform 1, and the first cleaning liquid delivery pipeline 2 extends along the first direction x;

[0044] A plurality of second cleaning liquid delivery pipelines 3, all communicating with the first cleaning liquid delivery pipeline 2. The plurality of second cleaning liquid delivery pipelines 3 are arranged at intervals along the first direction x, and the second cleaning liquid delivery pipelines 3 extend along the second direction y and are located between two adjacent air conditioner units 101;

[0045] A nozzle assembly 4, arranged on the second cleaning liquid delivery pipeline 3, and configured to selectively spray cleaning liquid onto the air conditioner units 101 on both sides; and

[0046] A ball screw assembly 5, configured to drive the cleaning platform 1 to move along the third direction z.

[0047] Specifically, the third direction z is the height direction. The ball screw assembly 5 can control the smooth rise and fall of the cleaning platform in the height direction to achieve full-coverage cleaning of the surface of the entire air conditioner unit. The first cleaning liquid delivery pipeline 2 is connected to the cleaning liquid source. The first cleaning liquid delivery pipeline 2 is the main pipeline for delivering the cleaning liquid, and the second cleaning liquid delivery pipeline 3 is a branch pipeline for delivering the cleaning liquid. The second cleaning liquid delivery pipeline 3 is located between every two adjacent air conditioner units 101, which can ensure that the cleaning liquid can be evenly distributed to each position to be cleaned through the nozzle assembly 4.

[0048] Specifically, the nozzle assembly 4 is used to spray the cleaning liquid onto the air conditioner units 101 on both sides at an appropriate spraying angle and pressure. The specific design of the nozzle can be adjusted according to actual requirements to achieve better cleaning effects.

[0049] Optionally, the cleaning liquid can be water or other solutions, etc. Pressurized components such as water pumps can be used to pressurize the cleaning liquid to a preset pressure to provide better cleaning effects.

[0050] Optionally, the pipe wall material of the first cleaning liquid delivery pipeline 2 and the second cleaning liquid delivery pipeline 3 can be a rigid material, such as iron, hard plastic, or stainless steel, etc. On the premise of setting support members for support, the delivery pipeline can also be a flexible hose.

[0051] The air conditioner unit cleaning system of this embodiment has a simple structure, can automatically clean multiple air conditioner units 101, has low labor costs and high cleaning efficiency; uses the ball screw assembly 5 to drive the cleaning platform to move along the third direction z, does not use chain drive, has a low failure rate, and is not prone to rust and corrosion when working in a humid production environment, which can reduce the maintenance workload; the stability of the cleaning platform is high due to the drive of the ball screw assembly 5, and it will not tilt, enabling the smooth lifting and lowering of the cleaning platform. The operating stability of the air conditioner unit cleaning system is high, thereby improving the working efficiency of the cleaning system; the cleaning system filters the filter on the primary filter screen, making the primary filter screen relatively clean and reusable, which can reduce the air resistance of the primary filter screen and reduce the energy consumption of the air conditioner unit's blower.

[0052] In some embodiments, as Figure 2 and Figure 3 shown, the ball screw assembly 5 includes:

[0053] A threaded rod 51 extending along the third direction z;

[0054] A nut 52 fixedly connected to the cleaning platform 1, and the nut 52 is movably sleeved outside the threaded rod 51 along the third direction z; and

[0055] A driving component 53 configured to drive the threaded rod 51 to rotate.

[0056] Specifically, the threaded rod 51 can control the rise or fall of the cleaning platform 1 by rotating clockwise or counterclockwise, and the driving component 53 can convert the output rotational motion into a linear motion of the nut 52 along the threaded rod 51.

[0057] Specifically, only one driving component 53 can be provided, which can reduce the production and maintenance costs compared with the existing technology of driving the chain by two motors on both sides. Optionally, the driving component 53 can be a driving motor, a hydraulic motor or other rotational driving components.

[0058] In this embodiment, the driving component 53 drives the threaded rod 51 to rotate, and then the nut 52 drives the cleaning platform to move up and down, which can provide precise and stable linear motion; the ball screw has small friction and high transmission efficiency, which can reduce energy consumption.

[0059] In some embodiments, as Figure 2 and Figure 3 shown, the driving component 53 is configured to drive the threaded rod 51 to rotate periodically in opposite directions, so that the cleaning platform 1 moves periodically back and forth along the third direction z.

[0060] Optionally, the periodic reverse rotation of the threaded rod 51 can be achieved by setting a timer, or can also be achieved by other electronic components. Optionally, a position sensor can be set according to needs to detect the actual position of the cleaning platform 1 to more precisely control its rise and fall.

[0061] In this embodiment, by making the cleaning platform 1 move periodically back and forth along the third direction z, the cleaning effect of the cleaning system can be improved.

[0062] In some embodiments, as Figure 2 shown, the air conditioner unit cleaning system further includes:

[0063] A limiting rod assembly 6, extending along the third direction z, the limiting rod assembly 6 passes through the cleaning platform 1 and is arranged at an interval from the threaded rod 51 along the first direction x.

[0064] Optionally, the limiting rod assembly 6 can include one limiting rod, or can also include two or more limiting rods.

[0065] In this embodiment, by setting the limiting rod assembly to pass through the cleaning platform 1, the rotation of the cleaning platform 1 in the horizontal plane can be restricted, ensuring the straightness of the cleaning platform 1 during movement, and improving the stability and safety of the cleaning system.

[0066] In some embodiments, as Figures 1 to 3 shown, the limiting rod assembly 6 includes a first limiting rod 61 and a second limiting rod 62. The first limiting rod 61 is arranged at the first end of the cleaning platform 1, the second limiting rod 62 is arranged at the second end of the cleaning platform 1, and the threaded rod 51 is located at the midpoint position between the first limiting rod 61 and the second limiting rod 62.

[0067] In this embodiment, two left and right limiting rods pass through the cleaning platform 1, which can further limit the rotation of the cleaning platform 1; the threaded rod 51 is located at the midpoint between the first limiting rod 61 and the second limiting rod 62, with both sides limited and the driving force located at the center of the cleaning platform 1, which can further improve the stability of the cleaning system.

[0068] In some embodiments, as Figure 1 shown, the nozzle assembly 4 includes:

[0071] Specifically, the first nozzles 41 and the second nozzles 42 spray the cleaning liquid towards the air conditioner units on both sides respectively, which can ensure that each air conditioner unit on each side can be cleaned. Since the first nozzles 41 and the second nozzles 42 are arranged at intervals along the second direction y, and the cleaning platform 1 reciprocates along the third direction z, they can effectively cover the entire surface of the air conditioner units on both sides, improving the cleaning efficiency.

[0072] Optionally, the first nozzles 41 and the second nozzles 42 can be of various types, such as fan nozzles or conical nozzles, etc., and can be selected according to the required spraying shape and coverage. Optionally, the spraying angle of the nozzles can be adjusted to ensure that the cleaning liquid can evenly cover the surface of the air conditioner unit. Optionally, the flow rate of each nozzle can also be adjusted through valves or other flow control devices to achieve a better cleaning effect.

[0073] In this embodiment, through the reasonable layout of the first nozzles 41 and the second nozzles 42, the air conditioner units 101 on both sides can be effectively cleaned, improving the cleaning quality and cleaning efficiency.

[0074] In some embodiments, as Figure 1 shown, the air conditioner unit cleaning system further includes:

[0075] A first on-off valve 11, provided at the liquid inlet section of the first cleaning liquid delivery pipeline 2, and the first on-off valve 11 is configured to control the on-off state between the cleaning liquid source and the nozzle assembly 4.

[0076] Specifically, by setting the first on-off valve 11, the main control of the first cleaning liquid delivery pipeline 2 can be achieved. On this basis, branch control valves can be not set to reduce the failure points, or branch control valves can be set to improve the cleaning flexibility.

[0077] Optionally, the first on-off valve 11 can be controlled by a manual operation handle, an electric actuator or a pneumatic actuator. Optionally, the first on-off valve 11 can also be integrated with other components of the cleaning system and be automatically controlled by a controller, such as automatically opening or closing according to the requirements of the cleaning program, etc.

[0078] In this embodiment, by setting the first on-off valve 11, the supply of the cleaning liquid can be effectively managed to ensure the stability and effectiveness of the entire cleaning process.

[0079] In some embodiments, as Figure 1 shown, the air conditioner unit cleaning system further includes:

[0080] A plurality of second on-off valves 22, which are respectively arranged on the liquid inlet sections of a plurality of second cleaning liquid delivery pipelines 3 and are configured to control the on-off state between the first cleaning liquid delivery pipeline 2 and the nozzle assembly 4.

[0081] Specifically, by setting the second on-off valves 22, the independent control of the second cleaning liquid delivery pipelines 3 can be achieved. Optionally, the second on-off valves 22 can be controlled by a manual operation handle, an electric actuator or a pneumatic actuator. Optionally, the second on-off valves 22 can also be integrated with other components of the cleaning system and be automatically controlled by a controller, such as automatically opening or closing according to the requirements of the cleaning program, etc.

[0082] In this embodiment, by setting the second on-off valves 22, the supply of the cleaning liquid can be effectively managed to ensure the stability and effectiveness of the entire cleaning process.

[0083] In some embodiments, the first on-off valve 11 and / or the second on-off valve 22 includes an electromagnetic valve.

[0084] In this embodiment, by setting the on-off valve as an electromagnetic valve, the response speed of the on-off valve to open or close can be increased, which is beneficial for the cleaning system to frequently switch the flow state of the cleaning liquid according to actual needs.
