[0052] Reference to "an embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Without conflict, the various embodiments in this application can be combined with each other.

[0053] It should be noted that the thickness, length, width, etc. of various components in the embodiments of this application shown in the drawings, as well as the overall thickness, length, width, etc. of the integrated device are only for illustrative purposes and should not constitute any limitation to this application.

[0054] The embodiments of this application provide an air-conditioning unit cleaning device for automatically cleaning components to be cleaned of a modular air conditioner. The air-conditioning unit cleaning device includes a spraying module, a pressurizing module, and a plurality of rotating modules. The spraying module includes a main pipeline, a plurality of branch pipelines, and a plurality of nozzles. The main pipeline communicates with the plurality of branch pipelines. Each branch pipeline is provided with a nozzle. The nozzle faces the component to be cleaned, and the nozzle is configured to spray liquid toward the component to be cleaned.

[0056] The embodiments of the present application will be further described below with reference to the accompanying drawings.

[0057] As shown in Figure 1 and Figure 2 An embodiment of the present application provides an air conditioning system 1000, including an air conditioner unit cleaning device 100 and an air conditioner device 200. The air conditioner unit cleaning device 100 is used to automatically clean the component 210 to be cleaned in the air conditioner device 200. Compared with the traditional manual cleaning of the air conditioner device 200, the present application can not only save costs, but also improve the cleaning efficiency and cleaning effect through automatic cleaning.

[0058] In one embodiment, the air conditioner device 200 includes a primary filter 2101, a surface cooler 2102, a fan 220, and a medium - efficiency filter 230. The primary filter 2101, the surface cooler 2102, the fan 220, and the medium - efficiency filter 230 are arranged in sequence. When the fan 220 operates, it can drive the air flow to pass through the primary filter 2101, the surface cooler 2102, and the medium - efficiency filter 230 in sequence.

[0059] In one embodiment, the component 210 to be cleaned includes at least one of the primary filter 2101 and the surface cooler 2102.

[0060] As an example, the following further describes the case where the component 210 to be cleaned includes the primary filter 2101 and the surface cooler 2102.

[0061] In one embodiment, the air conditioner unit cleaning device 100 includes a spraying module 10, a pressurizing module 20, and a plurality of rotating modules 30.

[0062] The spraying module 10 includes a main pipeline 11, a plurality of branch pipelines 12, and a plurality of spray heads 13. The branch pipelines 12 are rotatably connected to the main pipeline 11 relative to the main pipeline 11. The main pipeline 11 is used to transport the liquid for cleaning the component 210 to be cleaned to the branch pipelines 12. Each branch pipeline 12 is provided with a spray head 13. When the spray head 13 is in the open state, it can spray the liquid in the branch pipeline 12. The spray head 13 faces the component 210 to be cleaned. When the spray head 13 is in the open state, it can spray the liquid towards the component 210 to be cleaned to wash the component 210 to be cleaned and play a role in cleaning the component 210 to be cleaned.

[0063] The pressurization module 20 is connected to the pipeline. The pressurization module 20 is configured to pressurize the pipeline to increase the liquid pressure in the branch pipeline 12, thereby increasing the pressure of the liquid ejected by the nozzle 13 in the open state, improving the impact force of the liquid acting on the component 210 to be cleaned, and facilitating improving the flushing and cleaning effect on the component 210 to be cleaned.

[0064] Each rotation module 30 is connected to a branch pipeline 12. The rotation module 30 is configured to drive the branch pipeline 12 to rotate, so that the branch pipeline 12 drives the nozzle 13 to rotate, thereby adjusting the ejection direction of the nozzle 13, enabling the nozzle 13 to eject liquid towards the component 210 to be cleaned at multiple angles, and automatically flushing different positions of the component 210 to be cleaned, which is conducive to improving the cleaning efficiency and cleaning effect on the component 210 to be cleaned.

[0065] Moreover, through manual cleaning, the internal space of the air-conditioning device 200 needs to meet the requirement that staff can enter, resulting in a low utilization rate of the internal space of the air-conditioning device 200. In the embodiments of the present application, by arranging pipelines and nozzles 13 in the air-conditioning device 200, the occupied space is small, which is conducive to reducing the requirements for the internal space of the air-conditioning device 200, and thus improving the space utilization rate of the air-conditioning device 200.

[0066] In one embodiment, the liquid is water. In one embodiment, the liquid is a mixture of water and a cleaning agent.

[0067] As an example, the following further description is made taking water as the liquid.

[0068] In one embodiment, the main pipeline 11 is connected to the tap water pipeline.

[0069] In one embodiment, the main pipeline 11 and the branch pipeline 12 are made of stainless steel pipes, which is conducive to reducing the risk of corrosion and extending the service life.

[0070] In one embodiment, the pressurization module 20 is a water pump, which is simple and reliable and saves costs. In one embodiment, after being pressurized by the pressurization module 20, the water pressure in the branch pipeline 12 is not less than 1 MPa, which is conducive to improving the cleaning effect and cleaning efficiency on the component 210 to be cleaned.

[0071] In one embodiment, the nozzle 13 is a high-pressure water gun nozzle 13, which is simple and reliable and saves costs. In one implementation, the nozzle 13 is installed using a quick connector, which is convenient for installation and disassembly and is conducive to maintenance.

[0072] In one embodiment, the rotation module 30 is configured to drive the branch pipeline 12 to rotate up and down, so that the spray head 13 can rotate up and down to spray water on the component 210 to be cleaned. When the spray head 13 rotates and flushes the component 210 to be cleaned from top to bottom, the sprayed water acts on the surface of the component 210 to be cleaned from top to bottom, flushing the dust and water on the surface of the component 210 to be cleaned downward, which is conducive to reducing the adhesion of dust and water on the surface of the component 210 to be cleaned and improving the cleaning effect.

[0073] In one embodiment, the branch pipeline 12 and the main pipeline 11 are connected through a universal joint, which facilitates the relative rotation of the branch pipeline 12 with respect to the main pipeline 11 and is conducive to improving the reliability of rotation.

[0074] In one embodiment, the angle range for the rotation module 30 to control the up-and-down rotation of the branch pipeline 12 is ±45°. By rotating upward within a range of 45° and rotating downward within a range of 45°, it is conducive to taking into account the up-and-down scanning range and spraying force of the spray head 13. Among them, if the up-and-down scanning range of the spray head 13 is too large, although the flushing range will be increased, the flushing effect at the far end is not very good.

[0075] In one embodiment, the minimum distance between the spray head 13 and the component 210 to be cleaned is 50 cm. Combining with the up-and-down rotation of the spray head 13 by ±45°, a flushing area with a height of not less than 1 m can be formed on the component 210 to be cleaned, which is conducive to taking into account the up-and-down scanning range and spraying force of the spray head 13.

[0076] In one embodiment, the angle range for the rotation module 30 to control the up-and-down rotation of the branch pipeline 12 is ±180°, and the spray head 13 can spray water 360° along the vertical direction. At this time, the branch pipeline 12 and the spray head 13 can be arranged between the primary filter 2101 and the surface cooler 2102 (not shown in the figure), which is conducive to reducing the number of the branch pipeline 12 and the spray head 13, simplifying the structure of the air conditioner unit cleaning device 100, and saving costs.

[0077] In one embodiment, the angle range for the rotation module 30 to control the up-and-down rotation of the branch pipeline 12 can also be ±30°, ±60° or other values.

[0078] In one embodiment, the spray head 13 sprays water in the horizontal direction and sprays in a fan shape. Combining with its up-and-down rotation spraying, a flushing range similar to a rectangle can be formed on the surface of the component 210 to be cleaned, which is conducive to flushing and cleaning each position on the surface of the component 210 to be cleaned through the cooperation of multiple spray heads 13, and is conducive to improving the cleaning effect and cleaning efficiency of the component 210 to be cleaned.

[0079] In one embodiment, a plurality of nozzles 13 are provided on the same pipeline 12, and the plurality of nozzles 13 are arranged along the extending direction of the pipeline 12. By spraying water through the up-and-down rotation of the plurality of nozzles 13 in a transverse cooperation, each position on the surface of the component 210 to be cleaned can be flushed and cleaned, which is beneficial to improving the cleaning effect and cleaning efficiency of the component 210 to be cleaned. Among them, the extending direction of the pipeline 12 is parallel to the width direction of the primary filter 2101, the vertical direction is parallel to the height direction of the primary filter 2101, and the arrangement direction of the primary filter 2101, the surface cooler 2102, the fan 220 and the medium filter 230 is parallel to the thickness direction of the primary filter 2101.
