Description

Technical Field

[0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner outdoor unit cleaning device. 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 shell to overheat, which not only affects the stability and service life of the air conditioner, but may also cause malfunctions 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 shell, 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 shell and shorten 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 housing;

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The present invention discloses an air-conditioning external unit cleaning device, comprising: an air-conditioning housing, an outer surface of which is provided with heat dissipation mesh holes, and two sides of which are vertically provided with slide grooves; two lifting assemblies, which are arranged on both sides of the air-conditioning housing, and whose movable parts are connected with limit blocks located in the slide grooves; a third driving motor, which is connected with the corresponding limit blocks, and whose rotating ends are connected with side connecting rods; and two scrapers, one end of which is connected with the other end of the corresponding side connecting rods, and whose inner side edges are suitable for contacting with the outer surface of the air-conditioning housing; when it is necessary to clean the outer surface of the air-conditioning housing, the lifting assembly drives the scraper to rise and fall, and during the lifting process of the scraper, the third driving motor drives the scraper to swing back and forth, so as to clean the outer surface of the air-conditioning housing at multiple angles;

[0007] In this solution, the heat dissipation mesh is arranged on the outer side of the air-conditioning housing, 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 driving motor is fixed on the limit block, the output end of the third driving motor is connected to the side connecting rod, the other end of the side connecting rod is connected to the scraper, the third driving motor works, and the arc movement of the scraper is realized under the drive of the side connecting rod, the limit block is lifted and lowered through the lifting assembly, and then the scraper is driven to lift and lower; during the lifting process of the scraper, the scraper can realize arc-shaped swing, and the heat dissipation mesh is cleaned at multiple angles, the cleaning efficiency is high, and dust accumulation on the outer surface of the air-conditioning housing is avoided;

[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 which is longitudinally downwardly opened on the top of the air-conditioning 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 is 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 driven by the lifting assembly, and is turned upward to a vertical state driven by the third driving motor. Then, the arc plate descends driven 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.

[0012] In order to illustrate the specific structure of the lifting assembly, the lifting assembly adopted by the present invention includes: a second drive motor, which is fixed to the bottom of the side of the air conditioner housing; a vertically arranged threaded screw, one end of which is connected to the second drive motor; and the movable part, which is connected to the threaded screw;

[0013] The second drive motor is started to drive the threaded screw to rotate, thereby achieving the lifting and lowering of the movable part relative to the threaded screw.

[0014] In order to ensure that the side connecting rod is in a vertical state under the drive of the third driving motor, so as to facilitate the matching of the vertical scraper with the receiving groove, the present invention adopts the upper and lower surfaces of the limit block to be provided with limit notches, and when the side connecting rod is rotated to match with the limit notch, the scraper is in a vertical state;

[0015] The limiting notch plays a limiting role. When the third drive motor drives the side connecting rod to rotate to cooperate with the limiting notch, the side connecting rod is in a vertical state and the scraper is also in a vertical state. The scraper in the vertical state is easy to cooperate with the limiting notch.

[0016] In order to further increase the cooling of the air-conditioning housing, the present invention provides a heat dissipation fan on the surface of the air-conditioning housing.

[0017] In order to achieve cooling in the air-conditioning housing, the present invention adopts an exhaust port at the bottom of the air-conditioning housing, and the exhaust port is connected to the electrical chamber at the bottom of the air-conditioning housing for installing electrical components; the exhaust port is connected to the suction fan through an air guide duct, and the suction fan is driven by a first drive motor to work;

[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, so as to cool 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 the transmission belt always tensioned for transmission, the present invention adopts a workbench arranged under the air-conditioning shell, the workbench is provided with a rotating connecting seat, and the first driving motor is fixed on the connecting seat; the end of a guide rod is hinged on the workbench, the other end of the guide rod passes through the connecting seat, and a supporting 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 supporting surface and the bottom of the connecting seat.

[0021] Beneficial effects of the present invention: The present invention is an air conditioner outdoor unit cleaning device. In this solution, a heat dissipation fan and a heat dissipation mesh are arranged on the air conditioner housing, and a suction fan and an exhaust hole are additionally provided, thereby effectively improving the heat dissipation performance of the air conditioner housing; the suction fan is driven by a first driving 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 adopts 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, thereby reducing maintenance costs.

[0023] In addition, this solution also has an intelligent cleaning function; by driving the threaded screw to rotate through the second drive motor, 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.

[0024] In terms of waterproof function, the present invention adopts an arc-shaped design of the scraper and the storage groove, so that the present invention has a certain waterproof function; this design can drain water to both sides, avoiding the erosion of the air-conditioning shell caused by accumulated rainwater, thereby extending the service life of the equipment.
