Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air sweeping blade assembly and an air conditioner. Background Art

[0002] In the indoor unit of the air conditioner, the sweeping blade assembly is installed at the air outlet of the air conditioner to guide the air out of the air conditioner. During the long-term use of the air conditioner, dirt is easily accumulated on the sweeping blade, so the sweeping blade needs to be cleaned regularly. However, in the prior art, the active sweeping blade and the passive sweeping blade need to be disassembled separately, which is complicated to disassemble and assemble. Summary of the invention

[0003] Based on the above technical problems, the present invention aims to provide a wind sweeping blade assembly, which can simultaneously realize the disassembly and assembly of active wind sweeping blades and passive wind sweeping blades.

[0004] To solve the above problems, the present invention provides a wind sweeping blade assembly, comprising: a driving mechanism, a connecting rod, a first wind sweeping blade, a mounting plate and a plurality of second wind sweeping blades, the connecting rod being respectively connected to the first wind sweeping blade and all the second wind sweeping blades, the mounting plate being sequentially connected to all the second wind sweeping blades; the first wind sweeping blade is detachably connected to the mounting plate, and the first wind sweeping blade can rotate relative to the mounting plate; the driving mechanism is connected to the first wind sweeping blade, and the driving mechanism is suitable for driving the first wind sweeping blade to rotate reciprocatingly.

[0005] Therefore, through the connection between the first air-sweeping blade and the mounting plate, when the mounting plate is removed from the air outlet, the first air-sweeping blade and the second air-sweeping blade can be removed at the same time; when the mounting plate is installed, the first air-sweeping blade and the second air-sweeping blade can be installed at the same time, thereby simplifying the disassembly and assembly steps.

[0006] Optionally, the mounting plate includes a mounting plate body and a first clamping column, the first clamping column is connected to the mounting plate body, the first wind sweeping blade includes a first bayonet structure, the first bayonet structure is clamped together with the first clamping column, and the first clamping column is smaller than the inner diameter of the first bayonet structure, and the opening width of the first bayonet structure is smaller than the diameter of the first clamping column.

[0007] Thus, by setting the first bayonet structure and the first clamping column, the first wind sweeping blade can be quickly positioned, which is convenient for the disassembly and assembly of the first wind sweeping blade. On the other hand, the first bayonet structure is provided on the first wind sweeping blade to strengthen the first bayonet structure, so as to avoid the first bayonet structure being too weak due to the thickness of the mounting plate being too small, thereby preventing the first bayonet structure from failing after the first clamping column moves for a long time.

[0008] Optionally, the mounting plate includes an avoidance groove, and the first wind sweeping blade includes a connecting column; the connecting column is smaller than the inner diameter of the avoidance groove; the first bayonet structure is opened on the connecting column, and the first clamping column is connected to the avoidance groove.

[0009] Therefore, by respectively connecting the connecting plate with the inner side wall of the avoidance groove and the first clamping column, the first clamping column can be hidden, and interference between the first clamping column and other structures can be avoided.

[0010] Optionally, the mounting plate further includes a connecting plate, and the connecting plate is respectively connected to the avoidance groove and the first clamping column.

[0011] Therefore, by respectively connecting the connecting plate with the inner side wall of the avoidance groove and the first clamping column, the first clamping column can be hidden, and interference between the first clamping column and other structures can be avoided.

[0012] Optionally, the first clamping column protrudes from the connecting plate, or the connecting plate is provided with an avoidance structure suitable for avoiding the first bayonet structure.

[0013] Thus, interference of the connecting plate with the first bayonet structure can be avoided, and at the same time, the limiting effect of the connecting plate on the first bayonet structure, which causes the first wind sweeping blade to be unable to rotate, can be avoided.

[0014] Optionally, a limit opening structure is further provided on the connecting column, and the limit opening structure cooperates with the connecting plate to limit the rotation angle of the connecting column.

[0015] Therefore, by setting the limit opening structure, on the one hand, the interference between the limit opening structure and the connecting plate can be avoided, and on the other hand, the rotation angle of the first wind sweeping blade can be limited by the cooperation between the limit opening structure and the two side surfaces of the connecting plate.

[0016] Optionally, the cross-section of the limiting opening structure is a fan-shaped structure, and the curvature of the fan-shaped structure is between 90 degrees and 180 degrees.

[0017] Therefore, by limiting the curvature of the fan-shaped structure, it is possible to avoid that the first wind sweeping blade rotates too small an angle, resulting in a poor wind guiding effect, and it is also possible to avoid that the first wind sweeping blade and the connecting rod are damaged due to an excessively large rotation angle.

[0018] Optionally, the first wind sweeping blade further includes two limit plates, which are respectively arranged at two axial ends of the connecting column, and the two limit plates are respectively suitable for limiting cooperation with two side surfaces of the mounting plate body.

[0019] Therefore, the limiting plate cooperates with the two side surfaces of the mounting plate body to achieve axial positioning of the first air sweeping blade, thereby preventing the first air sweeping blade from being affected during operation.

[0020] Optionally, the second wind sweeping blade includes a first thinning structure, and the first thinning structure is connected to the mounting plate.

[0021] Therefore, the thickness of the connection between the second wind sweeping blade and the mounting plate is relatively low, so that the elasticity of the connection between the second wind sweeping blade and the mounting plate can be increased, which facilitates the rotation of the second wind sweeping blade and reduces the resistance of the second wind sweeping blade in movement.

[0022] Optionally, the second wind sweeping blade further includes a second thinning structure, the second thinning structure is connected to the connecting rod, and the first thinning structure and the second thinning structure have different width directions.

[0023] Thus, the thickness of the connection between the second wind sweeping blade and the connecting rod is relatively low, thereby increasing the elasticity of the connection between the second wind sweeping blade and the connecting rod, making it easier for the connecting rod to drive the second wind sweeping blade to rotate and reducing the resistance of the connecting rod in movement. The first thinning structure and the second thinning structure have different width directions, which can facilitate the adjustment of the wind direction.

[0024] Optionally, the cross section of the connecting rod is cross-shaped.

[0025] Thereby, the strength of the connecting rod can be increased, and instability phenomena such as arching and bending of the connecting rod when driving the second wind sweeping blade to move can be avoided, thereby improving the reliability of transmission.

[0026] Optionally, the connecting rod includes an avoidance portion, and the avoidance portion protrudes between two adjacent second wind-sweeping blades.

[0027] By providing the avoidance portion, interference between the wind sweeping blade assembly and the supporting structure or other structures can be avoided.

[0028] Optionally, the connecting rod is integrally connected to the second wind sweeping blade or is detachably connected to the second wind sweeping blade.

[0029] Thus, the connecting rod is detachably connected to the second wind sweeping blade, and the connecting rod and the second wind sweeping blade can be processed separately, which is convenient for molding the wind sweeping blade assembly. The connecting rod is integrally connected to the second wind sweeping blade, which can increase the connection strength between the connecting rod and the second wind sweeping blade and avoid failure of the clamping connection under multiple movements of the second wind sweeping blade.

[0030] Optionally, the connecting rod is integrally connected to the first wind sweeping blade or is detachably connected to the first wind sweeping blade.

[0031] Therefore, through the connection between the first wind sweeping blade and the connecting rod, the first wind sweeping blade drives the second wind sweeping blade to move through the connecting rod.

[0032] Optionally, it further includes a gear assembly, which includes at least two gears meshing in sequence, one of which is connected to the first wind sweeping blade, and one of which is connected to the driving end of the driving mechanism.

[0033] Therefore, through the setting of the gear assembly, the gear assembly is first driven to move by the driving mechanism, and then the first wind-sweeping blade is driven to move by the gear assembly. During disassembly and assembly, one of the gears can be disassembled and assembled together with the first wind-sweeping blade to release the coordination with the driving mechanism, thereby reducing the disassembly and assembly steps. At the same time, it avoids the direct connection between the driving mechanism and the first wind-sweeping blade, and it can also avoid unnecessary trouble caused by disassembling the driving mechanism when disassembling the first wind-sweeping blade.

[0034] The present invention also provides an air conditioner, comprising any of the above-mentioned sweeping blade assemblies. The air conditioner has the same beneficial effects as the above-mentioned sweeping blade assemblies, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0059] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0060] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0061] In the description of this specification, the description with reference to the terms "embodiment", "one embodiment" and "one implementation" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or implementation are included in at least one embodiment or implementation of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0062] The terms "first" and "second" etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0063] The present invention provides a wind sweeping blade assembly, such as Figures 1 to 10As shown, it includes: a driving mechanism 5, a connecting rod 33, a first wind sweeping blade 32, a mounting plate 34 and a plurality of second wind sweeping blades 31, the connecting rod 33 is respectively connected to the first wind sweeping blade 32 and all the second wind sweeping blades 31, the mounting plate 34 is connected to all the second wind sweeping blades 31 in sequence; the first wind sweeping blade 32 is detachably connected to the mounting plate 34, and the first wind sweeping blade 32 can rotate relative to the mounting plate 34; the driving mechanism 5 is connected to the first wind sweeping blade 32, and the driving mechanism 5 is suitable for driving the first wind sweeping blade 32 to rotate reciprocatingly.

[0064] It should be noted that if Fig. 9 As shown, the connecting rod 33 is connected to the top of the blade body of the first wind sweeping blade 32 and all the second wind sweeping blades 31 respectively, and the mounting plate 34 is connected to the root of all the second wind sweeping blades 31 in sequence. The mounting plate 34 is detachably mounted at the air outlet 4, and the mounting plate 34 is connected to the first wind sweeping blade 32 and all the second wind sweeping blades 31 respectively. The mounting plate 34 is mounted on the front end cover 2 and is located on the side of the front end cover 2 close to the air outlet passage of the air conditioner. Here, the mounting plate 34 is detachably connected to the first wind sweeping blade 32, and the mounting plate 34 is integrally connected to the second wind sweeping blade 31. When installing the wind sweeping blade assembly 3, the second wind sweeping blade 31 is first installed on the mounting plate 34, and then the mounting plate 34 is installed on the front end cover 2, and the first wind sweeping blade 32 is installed while the mounting plate 34 is installed.

[0065] The first wind sweeping blade 32 is equivalent to an active wind sweeping blade, and the gear assembly 6 is driven by the driving mechanism 5 to drive the first wind sweeping blade 32 to move; the second wind sweeping blade 31 is equivalent to a driven wind sweeping blade, and the first wind sweeping blade 32 drives all the second wind sweeping blades 31 to move at the same time through the connecting rod 33. The connecting rod 33 and the first wind sweeping blade 32 can be connected in one piece or by clamping. Through the connection between the first wind sweeping blade 32 and the connecting rod 33, the first wind sweeping blade 32 drives the second wind sweeping blade 31 to move through the connecting rod 33.

[0066] Therefore, by providing a plurality of second air sweeping blades 31 and connecting all of the second air sweeping blades 31 to the first air sweeping blades 32 via the connecting rods 33, when the first air sweeping blades 32 reciprocate, the second air sweeping blades 31 can be driven to rotate.

[0067] In one embodiment, Fig. 9 and Fig.10As shown, the first wind sweeping blade 32 includes a first blade body 321 and a third connecting column 323, a third bayonet structure 331 is provided on the connecting rod 33, and a third connecting column 323 is provided on the first blade body 321, the third bayonet structure 331 is engaged with the third connecting column 323, and the third connecting column 323 is smaller than the inner diameter of the third bayonet structure 331, and the opening width of the second bayonet structure 342 is smaller than the diameter of the third connecting column 323. Thus, through the bayonet connection between the connecting rod 33 and the first wind sweeping blade 32, the first wind sweeping blade 32 can be easily disassembled separately.

[0068] In addition, the first wind sweeping blade 32 further includes two limit plates 326, which are respectively arranged at the axial ends of the connecting column 322, and the two limit plates 326 are respectively suitable for limiting and cooperating with the two side surfaces of the mounting plate body 341. The distance between the two limit plates 326 is equal to the thickness of the mounting plate body 341. When the connecting column 322 is clamped in the second bayonet structure 342, the limit plates 326 are respectively limited and cooperating with the two side surfaces of the mounting plate body 341, so as to realize the axial positioning of the first wind sweeping blade 32, and avoid the first wind sweeping blade 32 from being affected during operation.

[0069] The advantage of such a configuration is that, through the connection between the first wind sweeping blade 32 and the mounting plate 34, when the mounting plate 34 is removed from the air outlet 4, the first wind sweeping blade 32 and the second wind sweeping blade 31 can be removed at the same time; when the mounting plate 34 is installed, the first wind sweeping blade 32 and the second wind sweeping blade 31 can be installed at the same time, thereby simplifying the disassembly and assembly steps.

[0070] In one embodiment, Fig. 9 and Fig.10As shown, the mounting plate 34 includes a second bayonet structure 342, and the first wind sweeping blade 32 includes a connecting column 322, or the mounting plate 34 includes a connecting column 322, and the first wind sweeping blade 32 includes a second bayonet structure 342; the second bayonet structure 342 is engaged with the connecting column 322, and the connecting column 322 is smaller than the inner diameter of the second bayonet structure 342, and the opening width of the second bayonet structure 342 is smaller than the diameter of the connecting column 322. By setting the second bayonet structure 342 and the connecting column 322, the first wind sweeping blade 32 is quickly positioned, and the first wind sweeping blade 32 is convenient to disassemble and assemble. On the other hand, the second bayonet structure 342 is provided on the first wind sweeping blade 32, so that the second bayonet structure 342 can be strengthened, so as to avoid the second bayonet structure 342 being too low in strength due to the too small thickness of the mounting plate 34, and causing the second bayonet structure 342 to fail after the connecting column 322 moves for a long time.

[0071] In one embodiment, Figures 11 to 14 As shown, the mounting plate 34 includes a mounting plate body 341 and a first clamping column 343, the first clamping column 343 is connected to the mounting plate body 341, and the first wind sweeping blade 32 includes a first bayonet structure 325, the first bayonet structure 325 is clamped and matched with the first clamping column 343, and the first clamping column 343 is smaller than the inner diameter of the first bayonet structure 325, and the opening width of the first bayonet structure 325 is smaller than the diameter of the first clamping column 343. Through the arrangement of the first bayonet structure 325 and the first clamping column 343, the first wind sweeping blade 32 is quickly positioned, and the first wind sweeping blade 32 is convenient for disassembly and assembly. On the other hand, the first bayonet structure 325 is provided on the first wind sweeping blade 32, so that the first bayonet structure 325 can be strengthened, so as to avoid the first bayonet structure 325 being too low in strength due to the too small thickness of the mounting plate 34, resulting in the failure of the first bayonet structure 325 after the first clamping column 343 moves for a long time.

[0072] In one embodiment, Figures 11 to 16 As shown, the mounting plate 34 includes an avoidance groove 344 , and the first wind sweeping blade 32 includes a connecting column 322 ; the connecting column 322 is smaller than the inner diameter of the avoidance groove 344 ; the first bayonet structure 325 is opened on the connecting column 322 , and the first clamping column 343 is connected to the avoidance groove 344 .

[0073] It should be noted that the first bayonet structure 325 is provided on the circumferential side wall of the connecting column 322. The mounting plate 34 further includes a connecting plate 345, and the connecting plate 345 is connected to the inner side wall of the avoiding groove 344 and the first clamping column 343, that is, the connecting plate 345 is connected to the circumferential surface of the first clamping column 343, and the first clamping column 343 is connected to the side wall of the avoiding groove 344 through the connecting plate 345. Therefore, by connecting the connecting plate 345 to the inner side wall of the avoiding groove 344 and the first clamping column 343, respectively, the first clamping column 343 can be hidden, and the interference of the first clamping column 343 with other structures can be avoided.

[0074] The advantage of such a configuration is that when the first bayonet structure 325 and the first clamping column 343 are clamped, the avoidance groove 344 can avoid the connecting column 322. Through the limiting effect of the avoidance groove 344 and the connecting column 322, in cooperation with the first bayonet structure 325 and the first clamping column 343, the double positioning of the first wind sweeping blade 32 is achieved.

[0075] In one embodiment, Fig.13 and Fig.14 As shown, Fig.14 The first clamping column 343 is a schematic diagram of protruding from the connecting plate 345, and the first clamping column 343 protrudes from both ends of the connecting plate 345. Here, the first clamping column 343 protrudes from both ends of the connecting plate 345 along the thickness direction of the mounting plate 34, and the first bayonet structure 325 is engaged with the first clamping column 343, thereby avoiding the interference of the connecting plate 345 with the first bayonet structure 325, and at the same time, avoiding the connection plate 345 from limiting the first bayonet structure 325, which causes the first wind sweeping blade 32 to be unable to rotate. At this time, Fig.15 and 16 As shown, Fig.16The schematic diagram of the cooperation between the limit opening structure 324 and the connecting plate 345 is shown in FIG. The connection column 322 is also provided with a limit opening structure 324, and the limit opening structure 324 cooperates with the connecting plate 345 to limit the rotation angle of the connection column 322. That is to say, since the position of the limit opening structure 324 corresponds to the position of the connecting plate 345, the width of the opening of the limit opening structure 324 is larger than the width of the opening of the first bayonet structure 325. Here, the limit opening structure 324 is located between the two first bayonet structures 325. Here, by setting the limit opening structure 324, on the one hand, the interference between the limit opening structure 324 and the connecting plate 345 can be avoided, and on the other hand, the rotation angle of the first wind sweeping blade 32 can be limited by the cooperation between the limit opening structure 324 and the two side surfaces of the connecting plate 345.

[0076] In one embodiment, Figures 17 to 22 As shown, Fig.18 To avoid the structural diagram of the structure 346 on the connecting plate 345, Fig. 20 Schematic diagram of the coordination between the limit opening structure and the connecting plate 345. Fig. 22 It is a schematic diagram of the structure in which the first bayonet structure 325 is engaged with the first engaging column 343. The connecting plate 345 is provided with an avoidance structure 346 suitable for avoiding the first bayonet structure 325. Here, the avoidance structure 346 can be an avoidance hole or an avoidance groove structure, and the first engaging column 343 is located at the avoidance structure 346. Since the first bayonet structure 325 is engaged with the first engaging column 343, the avoidance structure 346 can avoid the first bayonet structure 325. Therefore, by setting the avoidance structure 346, the interference between the first bayonet structure 325 and the connecting plate 345 can be avoided. At this time, Fig. 20 As shown, the connection column 322 is also provided with a limit opening structure 324, and the limit opening structure 324 cooperates with the connection plate 345 to limit the rotation angle of the connection column 322. There are two limit opening structures 324, and the two limit opening structures 324 are respectively located at the two ends of the first bayonet structure 325.

[0077] like Fig.16 and Fig.18 As shown, the cross section of the limit opening structure 324 is a fan-shaped structure, and the curvature of the fan-shaped structure is between 90 degrees and 180 degrees. Specifically, the curvature of the fan-shaped structure can be 90 degrees, 120 degrees, 150 degrees or 180 degrees. By limiting the curvature of the fan-shaped structure, it is possible to avoid the first wind sweeping blade 32 from rotating at too small an angle to cause poor wind guiding effect, and it is also possible to avoid the first wind sweeping blade 32 and the connecting rod 33 from rotating at too large an angle to cause damage.

[0078] like Figures 1 to 7 As shown, the wind sweeping blade assembly also includes a gear assembly 6, and the gear assembly 6 includes at least two gears meshing in sequence, one of which is connected to the first wind sweeping blade 32, and one of which is connected to the driving end of the driving mechanism 5.

[0079] It should be noted that the wind sweeping blade assembly 3 is suitable for guiding the air outlet of the air conditioner. The gear assembly 6 may include a first gear 61 and a second gear 62, wherein the first gear 61 and the first wind sweeping blade 32 may be integrally connected, key-connected or interference-fitted, and the drive mechanism 5 may use a servo motor, a stepper motor or other mechanism that can drive the gear assembly 6 to rotate; the second gear 62 is integrally connected, key-connected or interference-fitted with the driving end of the drive mechanism 5, and the driving end may be the rotating shaft of the motor. Of course, the gear assembly 6 may also include multiple gears, and only one of the gears needs to be connected to the first wind sweeping blade 32, and one of the gears needs to be connected to the driving end of the drive mechanism 5.

[0080] The advantage of such a configuration is that, through the configuration of the gear assembly 6, the driving mechanism 5 first drives the gear assembly 6 to move, and then drives the first wind sweeping blade 32 to move through the gear assembly 6. During disassembly and assembly, one of the gears can be disassembled and assembled together with the first wind sweeping blade to release the coordination with the driving mechanism 5, thereby reducing the number of disassembly and assembly steps. At the same time, it avoids the direct connection between the driving mechanism 5 and the first wind sweeping blade 32, and it can also avoid unnecessary trouble caused by disassembling the driving mechanism 5 when disassembling the first wind sweeping blade 32.

[0081] like Fig. 9 As shown, in one embodiment, the connecting rod 33 is detachably connected to the second wind sweeping blade 31. Specifically, the connecting rod 33 and the second wind sweeping blade 31 can be snap-fitted. The snap-fitting manner of the connecting rod 33 and the second wind sweeping blade 31 is the same as the snap-fitting manner of the connecting rod 33 and the first wind sweeping blade 32, which will not be repeated here. Thus, the connecting rod 33 and the second wind sweeping blade 31 can be processed separately to facilitate the molding of the wind sweeping blade assembly 3. In one embodiment, the connecting rod 33 is integrally connected to the second wind sweeping blade 31, which can increase the connection strength between the connecting rod 33 and the second wind sweeping blade 31 and avoid the failure of the snap-fit ​​connection under multiple movements of the second wind sweeping blade 31.

[0082] like Fig.17 and Fig.18As shown, the cross section of the connecting rod 33 is in a cross shape. Thus, the strength of the connecting rod 33 can be increased, and the connecting rod 33 can be prevented from being arched, bent, or other unstable phenomena when driving the second wind sweeping blade 31 to move, thereby improving the reliability of transmission.

[0083] like Figure 1 , Figure 2 and Fig.17 As shown, the connecting rod 33 includes an avoidance portion 332, and the avoidance portion 332 protrudes between two adjacent second wind sweeping blades 31. It should be noted that the cross section of the connecting rod 33 is a straight or cross-shaped structure. Since the air outlet 4 is also provided with a support structure for installing an air guide plate, or other structures, in order to avoid interference between the connecting rod 33 and the support structure or other structures of the air outlet, the connecting rod 33 may include a bent structure so that the avoidance portion 332 presents a raised structure. By setting the avoidance portion 332, interference between the wind sweeping blade assembly 3 and the support structure or other structures can be avoided.

[0084] like Figures 3 to 5 As shown, the indoor unit also includes an indoor unit body 1 and a front cover 2, the front cover is detachably connected to the indoor unit body 1, the air outlet 4 is opened on the front cover 2, the wind sweeping blade assembly 3 is installed on the front cover 2, the gear assembly 6 is rotatably connected to the front cover 2, and the driving mechanism 5 is installed on the front cover 2.

[0085] Here, the wind sweeping blade assembly 3 is installed on the side of the front cover 2 close to the air outlet passage of the air conditioner, and the gear assembly 6 and the driving mechanism 5 are located on the side of the front cover 2 away from the air outlet passage of the air conditioner. The front cover 2 and the indoor unit body 1 can be connected and matched by snap-fitting or screw-fastening. Figure 5 As shown, the front cover 2 also includes a positioning column 21, and the driving mechanism 5 includes a lug structure 51, and the lug structure 51 is detachably connected to the positioning column 21. Here, there are two lug structures 51 and two positioning columns 21, respectively, and the lug structure 51 is provided with an opening, and the positioning column 21 is provided with a screw hole, and the connection between the lug structure 51 and the positioning column 21 is achieved by passing a screw through the opening and the screw hole. Through the cooperation between the positioning column 21 and the lug structure 51, on the one hand, the disassembly of the driving mechanism is facilitated, and on the other hand, the suspended installation of the driving mechanism 5 can be achieved.

[0086] like Figure 5As shown, the gear drivingly connected to the driving end includes a rotating shaft, and the front end cover 2 also includes a positioning groove 22, and the rotating shaft is plugged into the positioning groove 22. That is to say, a rotating shaft is provided at one axial end of the second gear 62, and the rotating shaft is plugged into the positioning groove 22, and the rotating shaft can rotate relative to the positioning groove 22, that is, the diameter of the rotating shaft is smaller than the inner diameter of the positioning groove 22. Here, the positioning groove 22 is located between the two lug structures 51, and after the rotating shaft is inserted into the positioning groove 22, the second gear 62 can be positioned by the positioning groove 22 and the driving mechanism 5.

[0087] The advantage of such an arrangement is that, by respectively installing the wind sweeping blade assembly 3, the gear assembly 6 and the driving mechanism 5 on the front end cover 2, when the gear assembly 6 and the driving mechanism 5 need to be disassembled and assembled for maintenance, the front end cover 2 can be directly opened relative to the indoor unit body 1 to achieve disassembly and assembly of the gear assembly 6 and the driving mechanism 5.

[0088] like Figure 3 As shown, the front cover 2 is rotatably connected to the indoor unit body 1. Here, a positioning shaft is provided on the front cover 2, and a mounting hole is provided on the indoor unit body 1. The positioning shaft is passed through the mounting hole to realize the rotatable connection of the front cover 2 relative to the indoor unit body 1. The advantage of such a setting is that when the gear assembly 6 and the driving mechanism 5 are maintained, the front cover 2 does not need to be completely disassembled, avoiding unnecessary trouble.

[0089] like Fig.17 As shown, the second wind sweeping blade 31 includes a first thinning structure 35, and the first thinning structure 35 is connected to the mounting plate 34. Here, the second wind sweeping blade 31 also includes a blade root structure, and the first thinning structure 35 is connected to the blade root structure, and the blade root structure is connected to the mounting plate 34. The thickness of the connection between the second wind sweeping blade 31 and the mounting plate 34 is relatively low, so that the elasticity of the connection between the second wind sweeping blade 31 and the mounting plate 34 can be increased, which facilitates the rotation of the second wind sweeping blade 31 and reduces the resistance of the second wind sweeping blade 31 in the movement.

[0090] like Fig.17As shown, the second wind sweeping blade 31 also includes a second thinning structure 36, and the second thinning structure 36 is connected to the connecting rod 33, and the width directions of the first thinning structure 35 and the second thinning structure 36 are different. The width direction of the first thinning structure 35 refers to the length of the intersection line direction of the blade root structure and the first thinning structure 35, and the width of the second thinning structure 36 refers to the length of the intersection line direction of the second thinning structure 36 and the connecting rod 33. In other words, the thickness of the connection between the second wind sweeping blade 31 and the connecting rod 33 is relatively low, so that the elasticity of the connection between the second wind sweeping blade 31 and the connecting rod 33 can be increased, so that the connecting rod 33 can drive the second wind sweeping blade 31 to rotate, and reduce the resistance of the connecting rod 33 in the movement. The first thinning structure 35 and the second thinning structure 36 have different width directions, which can facilitate the adjustment of the wind direction.

[0091] like Figures 8 to 13 As shown, the mounting plate 34 includes a connector 347 , a slot 23 is provided on the front end cover 2 , and the connector 347 is plugged into and matched with the slot 23 .

[0092] Here, there are multiple connectors 347 and slots 23, respectively. When installing the wind sweeping blade assembly 3, first install the second wind sweeping blade 31 on the mounting plate 34, then align the connector 347 with the slot 23, and insert the connector 347 into the slot 23 to install the mounting plate 34. When the mounting plate 34 is installed, the first wind sweeping blade 32 is installed. The advantage of this arrangement is that, through the arrangement of the connector 347 and the slot 23, the mounting plate 34 can be quickly plugged in, and at the same time, the mounting plate 34 is also easily disassembled.

[0093] like Figures 8 to 13 As shown, the front end cover 2 includes a fourth bayonet structure 24, and the mounting plate 34 also includes a fourth bayonet column 348. The width of the opening of the fourth bayonet structure 24 is smaller than the diameter of the fourth bayonet column 348, and the fourth bayonet column 348 is bayonet-fitted with the fourth bayonet structure 24.

[0094] Here, the opening direction of the fourth bayonet structure 24 is the same as the opening direction of the slot 23. When the plug-in 347 and the slot 23 are aligned, the fourth clamping column 348 corresponds to the position of the fourth bayonet structure 24 at the same time. When the plug-in 347 is inserted into the slot 23, the fourth clamping column 348 can be clamped into the fourth bayonet structure 24 at the same time. Therefore, through the cooperation between the fourth clamping column 348 and the fourth bayonet structure 24, the mounting plate 34 can be quickly positioned.

[0095] The present invention further provides an air conditioner, comprising the wind sweeping blade assembly as described in any of the above embodiments. The air conditioner has the same beneficial effects as the wind sweeping blade assembly described above, which will not be described in detail here.

[0096] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
