[0010] In some embodiments of this utility model, the transmission assembly includes a second gear and a second connecting rod. The second gear is connected to the first gear so that the second gear rotates as the first gear rotates. One end of the second connecting rod is connected to one side of the second gear, and the other end of the second connecting rod is connected to the first connecting rod so that the first connecting rod slides back and forth on the base as the second gear rotates.

[0011] In some embodiments of this utility model, the transmission assembly further includes a third gear and a second transmission shaft. The second gear and the third gear are both disposed on the second transmission shaft. The third gear meshes with the first gear. The third gear rotates as the first gear rotates, and the second gear rotates as the third gear rotates.

[0012] In some embodiments of this utility model, a sliding groove is provided on the base, and a first limiting member and a second limiting member spaced apart from each other are provided in the sliding groove. The first connecting rod is slidably disposed in the sliding groove and located between the first limiting member and the second limiting member, so that the first connecting rod is restricted to slide between the first limiting member and the second limiting member under the drive of the transmission assembly.

[0029] Figures 1-2 As shown, this utility model provides a sweeping mechanism 200, which is installed in an air conditioner. The sweeping mechanism 200 includes a fan 410, a first gear 420, a sweeping body, and a transmission assembly. The fan 410 is installed at the air inlet 110 of the air conditioner and is configured to rotate under the action of airflow when the air conditioner has an air inlet 110. A first transmission shaft 430 connects the first gear 420 and the fan 410, so that the first gear 420 rotates as the fan 410 rotates. The sweeping body includes a base 310, a first connecting rod 320, and sweeping blades 330. The sweeping blades 330 are installed on the first connecting rod 320, which is slidably connected to the base 310. The sweeping body is configured to drive the sweeping blades 330 to rotate as the first connecting rod 320 slides on the base 310. The transmission assembly is configured to be connected to the first gear 420 and the first connecting rod 320 so that the first connecting rod 320 slides back and forth on the base 310 as the first gear 420 rotates.

[0030] The fan 410 can be located on both sides of the air inlet 110 or in the middle of the air inlet 110. It mainly uses the airflow passing through the air inlet 110 to drive the fan blades of the fan 410 to rotate.

[0031] The first gear 420 and the fan 410 can be located at both ends of the first drive shaft 430; or one can be located at the end and the other at the middle; or both can be located at the middle. That is, the arrangement of the first gear 420 and the fan 410 only needs to maintain a distance to ensure that the two do not interfere with each other.

[0032] The base 310 can be a separate structure or part of the middle frame at the air outlet of the air conditioner. Its purpose is to provide support for the sliding of the first link 320.

[0033] It is understood that this utility model sets the fan 410 at the air inlet 110 of the air conditioner, and drives the first connecting rod 320 to slide back and forth through the first gear 420 and the transmission assembly, thereby driving the sweeping blades 330 to rotate back and forth to sweep the air. This achieves the goal of reducing the energy consumption of the air conditioner by using the air force of the air conditioner to drive the sweeping blades 330 to sweep the air without the need to set a specific motor for the sweeping blades 330.

[0034] In some embodiments, the transmission assembly includes a second gear 510 and a second connecting rod 540. The second gear 510 is pulsatorically connected to the first gear 420 so that the second gear 510 rotates as the first gear 420 rotates. One end of the second connecting rod 540 is connected to one side of the second gear 510, and the other end of the second connecting rod 540 is connected to the first connecting rod 320 so that the first connecting rod 320 slides back and forth on the base 310 as the second gear 510 rotates.

[0035] One end of the second link 540 is connected to the side of the second gear 510 away from the first gear 420, and the other end of the second link 540 is connected to the first link 320, so that the circular motion of the second gear 510 can be converted into the linear reciprocating motion of the first link 320 through the second link 540.

[0036] The second gear 510 has a connecting post on the side opposite to the first gear 420. The connecting post is connected to the second connecting rod 540. By adjusting the position of the connecting post relative to the center of the second gear 510, the reciprocating sliding distance of the first connecting rod 320 can be adjusted. The further the connecting post is from the center, the longer the reciprocating sliding distance of the first connecting rod 320.

[0037] The first gear 420 and the second gear 510 can be connected and driven by a transmission component, or they can be directly meshed and driven.

[0038] In some embodiments, the transmission assembly further includes a third gear 520 and a second transmission shaft 530. The second gear 510 and the third gear 520 are both disposed on the second transmission shaft 530. The third gear 520 meshes with the first gear 420. The third gear 520 rotates as the first gear 420 rotates, and the second gear 510 rotates as the third gear 520 rotates.

[0039] The second gear 510 and the third gear 520 can be respectively set at both ends of the second transmission shaft 530; or one can be set at the end of the second transmission shaft 530 and the other at the middle of the second transmission shaft 530, or both can be set at the middle of the second transmission shaft 530, as long as the two do not interfere with each other and can rotate synchronously.

[0040] In some embodiments, a groove is provided on the base 310, and a first limiting member and a second limiting member spaced apart from each other are provided in the groove. The first connecting rod 320 is slidably disposed in the groove and located between the first limiting member and the second limiting member, so that the first connecting rod 320 is restricted to slide between the first limiting member and the second limiting member under the drive of the transmission assembly.

[0041] The slide groove is generally set along the length of the base 310, that is, it is set in the slide groove with the first connecting rod 320 and is fitted with the slide groove with a clearance.

[0042] Understandably, by setting a groove on the base 310 and placing the first connecting rod 320 in the groove, the first connecting rod 320 can slide on the base 310. At the same time, setting a first limiting member and a second limiting member in the groove can prevent the first connecting rod 320 from slipping out of the groove or from sliding excessively and damaging the sweeping blade 330.

[0043] In some embodiments, the first limiting member and the second limiting member are configured such that the distance between the first limiting member and the second limiting member on the slide is adjustable.

[0044] It is understandable that by adjusting the distance between the first and second limiting members, different reciprocating sliding distances of the first connecting rod 320 can be accommodated, thereby accommodating different sweeping angles.

[0045] In some embodiments, the bottom of the slide is provided with a plurality of spaced-apart holes, which are arranged along the length of the slide. The first limiting member and the second limiting member are configured to be plugged into any one of the holes.

[0046] Each socket can be fitted with a corresponding limiting device.

[0047] The first and second limiting components are identical in size and shape, and can be one of a block, baffle, or the like.

[0048] It is understandable that by adjusting the insertion of the first and second limiting members into two holes with different spacings, the distance between the first and second limiting members can be adjusted, thereby adapting to different reciprocating sliding distances of the first connecting rod 320.

[0049] In some embodiments, a plurality of spaced-apart insertion holes are provided on the sidewall of the slide, the plurality of insertion holes being arranged along the length direction of the slide, and the first limiting member and the second limiting member being configured to be plugged into any one of the insertion holes.

[0050] In some embodiments, the first limiting member and the second limiting member are inserted into the slide groove and are interference-fitted with the slide groove. By adjusting the position of the first limiting member and the second limiting member inserted into the slide groove, the distance between the first limiting member and the second limiting member can be adjusted.

[0051] In some embodiments, the sweeping blade 330 has a first connecting portion and a second connecting portion spaced apart from each other on one side. The first connecting portion is movably connected to the base 310, and the second connecting portion is connected to the first connecting rod 320.

[0052] The first connecting part is movably connected to the base 310, that is, the first connecting part can rotate relative to the base 310. If the base 310 is provided with a connecting hole, the first connecting part is a round shaft structure, and the round shaft is inserted into the connecting hole. As the first connecting rod 320 drives the second connecting part to move, the first connecting part can be driven to rotate, thereby causing the sweeping blade 330 to rotate; or the base 310 is provided with a round shaft structure, and the first connecting part is a hole structure. The round shaft is inserted into the hole structure, which allows the first connecting part to rotate relative to the round shaft structure, thereby rotating under the drive of the first connecting rod 320, realizing the swinging of the sweeping blade 330.

[0053] The second connecting part can be a shaft structure, which is inserted into the first connecting rod 320 so that the sweeping blade 330 rotates around the first connecting part under the drive of the first connecting rod 320.

[0054] The second connecting part can be a hole structure, and the first connecting rod 320 is provided with a shaft structure that is inserted into the hole structure.

[0055] In some embodiments, the sweeping blade 330 has a fixed shaft on one side, the first connecting rod 320 has a first strip hole, the length of the first strip hole is greater than the reciprocating sliding distance of the first connecting rod 320, the fixed shaft passes through the first strip hole and is rotatably connected to the base 310; a rack is provided on the side wall of the first strip hole, and a fourth gear is provided on the fixed shaft, the fourth gear meshing with the rack.

[0056] It is understandable that by setting a fourth gear on the fixed shaft and rotatably connecting the end of the fixed shaft to the base 310, the rack randomly drives the fourth gear to rotate when the first connecting rod 320 moves, thereby driving the fixed shaft to rotate and driving the sweeping blades 330 to rotate.

[0057] In some embodiments, the present invention further includes an indoor unit 100, which includes the above-mentioned air-sweeping mechanism 200. Since the air conditioner includes the above-mentioned air-sweeping mechanism 200, that is, includes some or all of the embodiments of the above-mentioned air-sweeping mechanism 200, the indoor unit 100 has the beneficial effects of some or all of the embodiments of the above-mentioned air-sweeping mechanism 200, which will not be described in detail here.

[0058] In some embodiments, the present invention also provides an air conditioner that includes the above-described indoor unit 100. Since the air conditioner includes the above-described indoor unit 100, that is, includes some or all of the embodiments of the above-described indoor unit 100, the air conditioner has the beneficial effects of some or all of the embodiments of the above-described indoor unit 100, which will not be described in detail here.

[0059] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the contents of the present utility model specification and drawings under the application concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
