Description
Technical Field
[0001] The present invention relates to the technical field of air conditioners, in particular to a cleaning device for an outdoor unit of an air conditioner. Background Art
[0002] When traditional modified air conditioners are running for a long time, the heat generated by the electrical components is difficult to be effectively discharged, causing the air conditioner casing to overheat, which not only affects the stability and service life of the air conditioner, but may also cause malfunction and damage. The driving components of traditional air conditioners are often fixedly installed, lack flexibility, and are not convenient for maintenance and replacement. Dust and other debris are easily accumulated on the front of the air conditioner casing, affecting the heat dissipation effect. Traditional cleaning methods are time-consuming and labor-intensive, with limited effects. Traditional air conditioners also have defects in waterproof design. Accumulated rainwater can easily erode the air conditioner casing, shortening the service life of the equipment.
[0003] In summary, how to clean the outdoor unit of the air conditioner and avoid dust accumulation on the front (outer surface) of the air conditioner shell has become an urgent problem that researchers in this field need to solve. Summary of the Invention
[0004] The technical problem to be solved by the present invention is: how to clean the outdoor unit of the air conditioner and avoid dust accumulation on the outer surface of the air conditioner shell;
[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0006] The present invention is a cleaning device for an outdoor unit of an air conditioner, comprising: an air-conditioning casing, an outer surface of which is provided with a heat dissipation mesh, and slide grooves are vertically opened on both sides of the air-conditioning casing; two lifting assemblies are arranged on both sides of the air-conditioning casing, and a movable portion thereof is connected to a limit block located in the slide groove; a third driving motor is connected to the corresponding limit block, and a rotating end thereof is connected to a side connecting rod; and two scrapers, one end of which is connected to the other end of the corresponding side connecting rod, and the inner side edge of which is suitable for contacting the outer surface of the air-conditioning casing; when it is necessary to clean the outer surface of the air-conditioning casing, the lifting assembly drives the scrapers to rise and fall, and during the lifting process of the scrapers, the third driving motor drives the scrapers to swing back and forth, so as to clean the outer surface of the air-conditioning casing at multiple angles;
[0007] In this solution, the heat dissipation mesh is arranged on the outer side surface of the air-conditioning casing, the fan of the air-conditioning faces the heat dissipation mesh, the movable part of the lifting assembly is lifted and lowered in the slide groove, the third drive motor is fixed on the limit block, the output end of the third drive motor is connected to the side connecting rod, and the other end of the side connecting rod is connected to the scraper. When the third drive motor is working, the scraper is driven by the side connecting rod to realize the arc movement of the scraper, and the limit block is lifted and lowered by the lifting assembly, thereby driving the scraper to lift and lower; during the lifting process of the scraper, the scraper can realize arc-shaped swing, clean the heat dissipation mesh at multiple angles, and the cleaning efficiency is high, thereby avoiding dust accumulation on the outer surface of the air-conditioning casing;
[0008] It should be noted that the inner side of the scraper is a flexible part such as a brush. During the arc-shaped swinging process of the scraper, the flexible part will be compressed to efficiently clean the heat dissipation mesh.
[0009] In order to store the scraper, the present invention adopts a storage groove provided longitudinally downwardly on the top of the air conditioner housing; the tops of the two slide grooves are connected to each other to form the storage groove; when the scraper rises to the upper limit position, the third drive motor drives the scraper to rotate to a vertical state and be located above the storage groove, and then the lifting assembly drives the scraper to descend and store the scraper in the storage groove;
[0010] The scraper moves to the upper limit position under the drive of the lifting assembly, and is turned upward to a vertical state under the drive of the third drive motor. Then, the arc plate is driven down by the lifting assembly, so that the scraper is in a vertical state and is located in the storage groove, thereby realizing the storage of the scraper;
[0011] The outer edge of the scraper is an arc-shaped structure. When the scraper is in the storage state, the upper surface of the scraper is arc-shaped, and rainwater is not easily retained in the storage groove, thereby avoiding the erosion of the air conditioner shell by rainwater.

[0018] The first drive motor works to drive the suction fan to work, and the suction fan generates negative pressure to extract the heat in the air-conditioning shell from the exhaust port at the bottom of the air-conditioning shell, thereby cooling the air-conditioning shell.
[0019] In order to illustrate how the suction fan cooperates with the first drive motor, the present invention adopts a pulley and a transmission belt to transmit power between the first drive motor and the suction fan.
[0020] In order to keep the pulley and transmission belt always tensioned and transmitted, the present invention adopts a workbench provided under the air-conditioning shell, a rotating connecting seat is provided on the workbench, and the first driving motor is fixed on the connecting seat; the end of the guide rod is hinged on the workbench, and the other end of the guide rod passes through the connecting seat, and a support surface is provided at one end of the guide rod close to the hinge, and an extrusion spring is sleeved on the guide rod, and the two ends of the extrusion spring are respectively against the support surface and the bottom of the connecting seat.

This solution provides a heat dissipation fan and a heat dissipation mesh on the air conditioner housing, and adds a suction fan and an exhaust hole design, which effectively improves the heat dissipation performance of the air conditioner housing; the suction fan is driven by a first drive motor through a pulley, and can efficiently discharge the heat generated by the electrical components in the modified electrical chamber to the outside, thereby ensuring the long-term stable operation of the modified air conditioner housing;
[0022] In terms of drive component design, this solution uses the combination of guide rods and connecting seats to realize the position adjustment of the drive component (including the first drive motor and the suction fan) on the workbench, so that the distance between them can be easily controlled and the tension of the transmission belt can be adjusted; this design not only improves the flexibility of the equipment, but also facilitates the replacement of the pulley after long-term use, reducing maintenance costs.
[0023] In addition, this solution also has an intelligent cleaning function; through the second drive motor to drive the threaded screw to rotate, and the coordinated work of the movable part, limit block, side connecting rod and scraper, the front of the air-conditioning casing can be automatically cleaned, effectively avoiding the blockage of the cooling fan and the cooling mesh caused by dust, thereby ensuring the heat dissipation effect; at the same time, the scraper can also be retracted into the storage slot for storage, reducing the occupied area.
