[0035] In related technologies, to effectively prevent dust or lint from entering the outdoor unit of an air conditioner, a filter is generally installed at the air intake assembly of the outdoor unit to filter dust or lint. However, after prolonged use, existing outdoor units accumulate excessive dust or lint on the filter, hindering airflow into the unit and affecting its heat dissipation efficiency.

[0036] Reference Figures 1 to 5 According to the first aspect of the present invention, the air intake assembly of an air conditioner outdoor unit includes an air intake plate 100, a filter 200, a scraping assembly 300, and a drive assembly 400. The air intake plate 100 is provided with ventilation holes 101. The filter 200 is disposed on the air intake plate 100 to block the ventilation holes 101. The scraping assembly 300 is rotatably disposed on the air intake plate 100 and abuts against the filter 200. The drive assembly 400 is disposed on the air intake plate 100, and the output end of the drive assembly 400 is connected to the scraping assembly 300 to drive the scraping assembly 300 to rotate. Thus, when there is too much dust or lint attached to the filter 200, the drive assembly 400 can drive the scraping assembly 300 to rotate, so that the scraping assembly 300 can scrape off the dust or lint attached to the filter 200, ensuring that air can smoothly enter the interior of the air conditioner outdoor unit, thereby improving the heat dissipation efficiency of the air conditioner outdoor unit.

[0037] Specifically, the air inlet plate 100 is installed over the air inlet of the outdoor unit of the air conditioner. When the outdoor unit is working, outdoor air enters the interior of the outdoor unit through the air inlet and exchanges heat with the condenser. By installing a filter screen 200 on the air inlet plate 100, external dust or lint can be prevented from entering the interior of the outdoor unit. When there is too much dust or lint attached to the filter screen 200, the scraping component 300 can be driven to rotate by the drive component 400 so that the scraping component 300 can scrape off the dust or lint attached to the filter screen 200, ensuring that air can smoothly enter the interior of the outdoor unit, thereby improving the heat dissipation efficiency of the outdoor unit.

[0038] It should be noted that the drive component 400 is a power component such as a stepper motor or a servo motor, and there are no restrictions on its use.

[0039] In some embodiments of this utility model, the air intake assembly of the outdoor unit of the air conditioner is provided with a fixing structure. The fixing structure is used to restrict the separation of the filter 200 from the air intake plate 100, so as to prevent the filter 200 from becoming loose under the action of the scraping assembly 300, thereby improving the installation reliability of the filter 200.

[0040] In some embodiments of this utility model, the fixing structure includes a fixing ring 500 and an annular protrusion 102 provided on the side wall of the ventilation hole 101. The fixing ring 500 is housed in the ventilation hole 101 and threadedly connected to the side wall of the ventilation hole 101. The filter screen 200 is sandwiched between the fixing ring 500 and the annular protrusion 102 to prevent the filter screen 200 from becoming loose under the action of the scraping assembly 300, thereby improving the installation reliability of the filter screen 200.

[0041] Specifically, the retaining ring 500 is provided with an external thread, and the side wall of the ventilation hole 101 is provided with an internal thread that matches the external thread. When installing the filter screen 200, the filter screen 200 is placed on the side of the annular protrusion 102 facing the retaining ring 500. Then, the retaining ring 500 is rotated so that the retaining ring 500 moves closer to the annular protrusion 102. When the filter screen 200 is sandwiched between the retaining ring 500 and the annular protrusion 102, the installation of the filter screen 200 is completed. This can limit the axial movement of the filter screen 200 along the through hole, so as to prevent the filter screen 200 from becoming loose under the action of the scraping assembly 300, thereby improving the installation reliability of the filter screen 200.

[0042] It should be noted that the fixing structure can also be a bolt and nut structure, with the bolt passing through the filter screen 200 and the nut of the bolt abutting against the filter screen 200, and the thread engaging with the bolt thread, which also facilitates the installation of the filter screen 200.

[0043] In another embodiment, the filter 200 is also fixed to the annular protrusion 102 by adhesive bonding, which is not limited here.

[0044] In some embodiments of this utility model, a pull member 510 is connected to the side of the fixing ring 500 away from the annular protrusion 102, which makes it convenient for workers to assemble and disassemble the fixing ring 500.

[0045] Specifically, the pull member 510 has a columnar structure. When disassembling the fixing ring 500, the operator can use the pull member 510 to rotate the fixing ring 500 so that the fixing ring 500 moves away from the annular protrusion 102. When disassembling the fixing ring 500, the operator can use the pull member 510 to rotate the fixing ring 500 in the opposite direction so that the fixing ring 500 moves towards the annular protrusion 102. The operation is simple, convenient and quick, and can facilitate the operator to disassemble and assemble the fixing ring 500.

[0046] It should be noted that the pull component 510 and the fixed ring 500 are an integral structure, which can reduce the number of molds and reduce the production cost of the molds. No restrictions are imposed here.

[0047] It should be noted that the pull member 510 can also be connected to the retaining ring 500 by means of a threaded connection, which will not be described in detail here.

[0048] In some embodiments of this utility model, the scraping component 300 includes a connecting shaft 310, a brush 330, and a connecting strip 320. The connecting shaft 310 is connected to the output end of the drive component 400, one end of the connecting strip 320 is connected to the outer peripheral surface of the connecting shaft 310, and the brush 330 is disposed on the connecting strip 320. The brush 330 abuts against the filter screen 200, which can improve the scraping efficiency of the scraping component 300.

[0049] Specifically, the brush 330 has a flexible structure and is located at the end of the connecting strip 320 away from the connecting shaft 310, with the brush 330 facing the filter screen 200. The output end of the drive assembly 400 is fixedly connected to the connecting shaft 310 to drive the brush 330 to rotate. The brush 330 can enter the mesh of the filter screen 200 to clean the dust or lint inside the mesh of the filter screen 200, thereby improving the scraping efficiency of the scraping assembly 300.

[0050] In some embodiments of this utility model, three connecting strips 320 are configured, and the three connecting strips 320 are arranged at intervals along the circumference of the connecting shaft 310. Three brushes 330 are configured accordingly. By increasing the number of brushes 330, the scraping efficiency of the brushes 330 can be improved.

[0051] Specifically, along the circumference of the connecting shaft 310, three connecting strips 320 are evenly spaced, and each connecting strip 320 corresponds to a brush 330. When the connecting shaft 310 rotates once, the same position of the filter screen 200 is scraped three times by the scraping component 300. By increasing the number of brushes 330, the scraping efficiency of the brushes 330 can be improved.

[0052] Of course, in other specific embodiments, the number of connecting strips 320 may also be configured to be two or four, etc., and there is no limitation here.

[0053] In some embodiments of this utility model, a reinforcing member 340 is provided between adjacent connecting strips 320, which can provide structural stability to the scraping assembly 300.

[0054] Specifically, the reinforcing member 340 is an arc-shaped strip structure. One end of the reinforcing member 340 is connected to one of the adjacent connecting strips 320, and the other end of the reinforcing member 340 is connected to the other adjacent connecting strip 320. This can limit the circumferential swing of the connecting strip 320 along the connecting shaft 310 and provide structural stability to the scraping assembly 300.

[0055] In some embodiments of this utility model, the air inlet plate 100 includes a frame 110 and a grille assembly 120. The ventilation hole 101 is disposed in the frame 110, and the grille assembly 120 is housed in the ventilation hole 101 and connected to the inner circumferential surface of the ventilation hole 101. This allows for preliminary filtration of dust or lint, thereby improving the service life of the filter screen 200.

[0056] Specifically, the grille assembly 120 includes multiple grille bars 121 and multiple grille rings 122. The multiple grille bars 121 have smoke ventilation holes 101 evenly spaced in the circumference. The multiple grille rings 122 are coaxially arranged and have different diameters. Each grille ring 122 is connected to multiple grille bars 121, which can perform preliminary filtration of dust or lint to improve the service life of the filter 200.

[0057] It should be noted that the grid assembly 120 can also use multiple grid pieces with array spacing, and there is no limitation on this.

[0058] In some embodiments of this utility model, the grille assembly 120 and the frame 110 are an integral structure, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the air intake assembly of the air conditioner outdoor unit.

[0059] Specifically, the grille assembly 120 and the frame 110 can be integrally molded by injection molding, which can reduce the number of molds and reduce the production cost of the molds, thereby reducing the production cost of the air intake assembly of the air conditioner outdoor unit.

[0060] As another implementation, the grille assembly 120 and the frame 110 can also be connected by welding. The welding methods include, but are not limited to, resistance welding, ultrasonic welding or laser welding, which will not be described in detail here.

[0061] Reference Figure 1 , Figure 2According to the second aspect of the present invention, the outdoor unit of the air conditioner includes the air intake assembly of the outdoor unit of the air conditioner according to the first aspect of the present invention. When there is too much dust or lint attached to the filter 200, the scraping assembly 300 can be driven to rotate by the driving assembly 400 so that the scraping assembly 300 can scrape off the dust or lint attached to the filter 200, ensuring that air can smoothly enter the interior of the outdoor unit of the air conditioner, thereby improving the heat dissipation efficiency of the outdoor unit of the air conditioner.

[0062] Specifically, in the air intake assembly of the outdoor unit of the air conditioner according to the first aspect embodiment of this utility model, the air intake plate 100 is covered on the air intake of the outdoor unit. When the outdoor unit is working, outdoor air enters the interior of the outdoor unit from the air intake and exchanges heat with the condenser. By setting a filter screen 200 on the air intake plate 100, external dust or lint can be prevented from entering the interior of the outdoor unit. When there is too much dust or lint attached to the filter screen 200, the scraping component 300 can be driven to rotate by the driving component 400 so that the scraping component 300 can scrape off the dust or lint attached to the filter screen 200, ensuring that air can smoothly enter the interior of the outdoor unit, thereby improving the heat dissipation efficiency of the outdoor unit.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
