Detailed Implementation

[0068] Air conditioners can be used to regulate ambient temperature and humidity. When using an air conditioner, the air swing device can change the direction of the airflow, meaning it acts as a guide. The air swing device provided by related technologies includes swing blades; controlling the rotation of these blades adjusts the direction of the airflow. Typically, the air swing device includes multiple swing blades. A motor drives the central swing blade to rotate, and the central blade, via a connecting rod, drives the swing blades on either side to rotate. Due to stroke errors during this operation, the swing blades on either side are prone to vibration, resulting in a poor user experience.

[0069] The air conditioner provided in this embodiment can improve the problem of the air sweeping blades easily vibrating and improve the user experience.

[0070] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0071] This embodiment provides an air conditioner that can be used to regulate the temperature or humidity of the environment.

[0072] It should be noted that the air conditioner in this embodiment refers to the indoor unit of the air conditioner; in other embodiments, the air conditioner may also refer to the indoor unit of the air conditioner and the outdoor unit of the air conditioner used in conjunction with it, which is not specifically limited here.

[0073] It should also be noted that the air conditioner in this embodiment refers to a floor-standing air conditioner; in other embodiments, the air conditioner may also refer to a wall-mounted air conditioner, which is not specifically limited here.

[0074] An air conditioner also includes a cabinet, a heat exchanger, and a fan (not shown in the figure). The cabinet is equipped with an air outlet. The heat exchanger and the fan are both located inside the cabinet. The heat exchanger is used to exchange heat with the air, and the fan is used to blow the air that has been heated by the heat exchanger out from the air outlet, thereby achieving the function of regulating the ambient temperature using the air conditioner.

[0075] The air conditioner also includes a sweeping device 010 (such as...) Figure 1 As shown, the air sweeping device 010 is installed in the cabinet and located at the air outlet. The air sweeping device 010 is used to adjust the flow direction of the gas blown out from the air outlet, that is, to adjust the air outlet direction.

[0076] Please refer to Figure 1 and Figure 2 The air-sweeping device 010 includes an air-sweeping blade 110, an air outlet frame 100, and a motor 120. The air-sweeping blade 110 is rotatably mounted on the air outlet frame 100. The motor 120 is driven by the air-sweeping blade 110 and is used to drive the air-sweeping blade 110 to swing, thereby adjusting the air outlet direction of the air conditioner.

[0077] Furthermore, the air-sweeping device 010 also includes a connecting rod 300 and at least two cranks 200. The connecting rod 300 and the motor 120 are connected by transmission through one of the cranks 200, and the connecting rod 300 and the air-sweeping blade 110 are connected by transmission through the other crank 200. When the motor 120 drives the crank 200 connected to it to swing, the crank 200 drives the connecting rod 300 to swing, and the connecting rod 300 drives the crank 200 that connects the connecting rod 300 and the air-sweeping blade 110 to swing. By driving the air-sweeping blade 110 to swing through this crank 200, the air outlet direction of the air conditioner can be adjusted.

[0078] The motor 120 drives the crank 200 connected to it, which in turn drives the connecting rod 300 to swing. The swinging connecting rod 300 then drives the crank 200, which is connected to the connecting rod 300 and the sweeping blade 110, to swing. The crank 200, which is connected to the connecting rod 300 and the sweeping blade 110, drives the sweeping blade 110 to rotate. In other words, the transmission between the crank 200 and the connecting rod 300 can make the sweeping blade 110 rotate smoothly, reducing the vibration of the sweeping blade 110. This reduces the vibration of the sweeping device 010 and improves the user experience.

[0079] The number of sweeping blades 110 can be set as needed. In a preferred embodiment, the sweeping device 010 includes multiple sweeping blades 110, each of which is connected to the connecting rod 300 via its corresponding crank 200. That is, the number of cranks 200 used to connect the sweeping blades 110 and the connecting rod 300 is the same as the number of sweeping blades 110, so that each sweeping blade 110 is connected to the connecting rod 300 via a crank 200. The arrangement of multiple sweeping blades 110 ensures good airflow direction control. Furthermore, the fact that multiple sweeping blades 110 are connected to the connecting rod 300 via cranks 200 ensures reliable and smooth rotation of all blades 110, reducing stroke error during rotation and minimizing vibration.

[0080] It should be noted that the above-mentioned multiple sweeping blades 110 refer to two or more; of course, in other embodiments, the number of sweeping blades 110 may also be one, which is not specifically limited here.

[0081] Further, please refer to Figure 3 and Figure 4 The connecting rod 300 includes a drive unit 310 and a transmission unit 320, which are connected at an angle. The transmission unit 320 extends linearly along a preset direction, and multiple sweeping blades 110 are arranged sequentially along the preset direction. The drive unit 310 is connected to the motor 120 via one of the cranks 200. In this way, the transmission unit 320 of the connecting rod 300, which drives the multiple sweeping blades 110, and the multiple sweeping blades 110 all extend along the preset direction. This ensures that the connecting rod 300 reliably drives the multiple sweeping blades 110 to rotate simultaneously, thereby ensuring the reliability of the airflow direction adjustment and facilitating the synchronization of the rotation of the multiple sweeping blades 110, reducing the vibration problem during operation of the sweeping device 010. Furthermore, the drive unit 310 and the transmission unit 320 are connected at an angle, and the drive unit 310 is connected to the motor 120 via the crank 200. This arrangement ensures that the crank 200 (i.e., the driving crank) connecting the motor 120 and the connecting rod 300 is located at one end of the connecting rod 300, while the multiple cranks 200 (i.e., the driven cranks) connecting the connecting rod 300 and the multiple sweeping blades 110 are arranged along a preset direction and distributed on one side of the crank 200 connecting the motor 120 and the connecting rod 300. In this way, the multiple sweeping blades 110 can be driven by their respective corresponding cranks 200 to reduce the stroke error during rotation, thereby improving the problem of easy vibration of the sweeping device 010 and enhancing the user experience.

[0082] The preset direction in this embodiment is horizontal, that is, multiple sweeping blades 110 are arranged in sequence along the horizontal direction, and the transmission part 320 extends along the horizontal direction. In this way, the sweeping blades 110 can be rotated along the rotation axis extending in the vertical direction to adjust the air outlet direction.

[0083] Of course, in other embodiments, the preset direction can also be vertical, that is, multiple sweeping blades 110 are arranged sequentially in the vertical direction, and the transmission part 320 extends in the vertical direction. In this way, the sweeping blades 110 can be rotated along the rotation axis extending in the horizontal direction to adjust the air outlet direction. In other embodiments, the preset direction can also be at an angle to the horizontal direction or at an angle to the vertical direction, which is not specifically limited here.

[0084] It should be noted that, please refer to Figure 4 The included angle α between the drive unit 310 and the transmission unit 320 can be set as needed, such as 120°, 135°, etc., and is not specifically limited here.

[0085] It should also be noted that the above-mentioned horizontal and vertical directions are relative directions based on the usage state of the air conditioner in this embodiment or the state shown in the attached drawings.

[0086] Please refer to Figure 5 and Figure 6 The air-sweeping device 010 in this embodiment also includes an auxiliary connecting rod 330, which is connected to multiple air-sweeping blades 110. By setting the auxiliary connecting rod 330, the synchronicity of the rotation of the multiple air-sweeping blades 110 can be further ensured. On the one hand, the air outlet direction can be reliably adjusted, and on the other hand, by ensuring the synchronous rotation of the air-sweeping blades 110, the problem of easy shaking during operation of the air-sweeping device 010 can be reduced.

[0087] It should be noted that the connection method between the auxiliary link 330 and the sweeping blade 110 can be selected as needed. In this embodiment, the auxiliary link 330 and the sweeping blade 110 are engaged.

[0088] It should also be noted that the number of auxiliary links 330 can be selected as needed. In a preferred embodiment, the number of auxiliary links 330 is greater than or equal to two, and each auxiliary link 330 is connected to multiple sweeping blades 110, with the multiple auxiliary links 330 distributed at intervals along the extension direction of the rotation axis of the sweeping blades 110. Of course, in some embodiments, only one auxiliary link 330 may be provided, or no auxiliary link 330 may be provided, and no specific limitation is made here.

[0089] In this embodiment, the crank 200 that drives the motor 120 and the connecting rod 300 has the same structure as the crank 200 that drives the sweeping blade 110 and the connecting rod 300; of course, in other embodiments, the crank 200 that drives the motor 120 and the connecting rod 300 has a different structure than the crank 200 that drives the sweeping blade 110 and the connecting rod 300.

[0090] Please refer to Figure 4 and Figure 7 In this embodiment, the crank 200 includes a crank body 201, which is connected to the motor 120 and the connecting rod 300, or to the sweeping blade 110 and the connecting rod 300.

[0091] Please refer to Figure 7 , Figure 8 and Figure 9 The crank body 201 includes a first connecting part 210, a transition part 220, and a second connecting part 230. The first connecting part 210 and the second connecting part 230 are both connected to the transition part 220 at an angle. The first connecting part 210 is driven to the connecting rod 300, and the second connecting part 230 is driven to the motor 120 or the sweeping blade 110. The connecting rod 300 and the second connecting part 230 are distributed at intervals along the extension direction of the rotation axis c of the sweeping blade 110.

[0092] Since both the first connecting portion 210 and the second connecting portion 230 are connected at an angle to the transition portion 220, the first connecting portion 210 and the second connecting portion 230 are connected by a bend through the transition portion 220. The first connecting portion 210 is connected to the connecting rod 300 in a transmission manner. Along the extension direction of the rotation axis c of the sweeping blade 110, the second connecting portion 230 is distributed at intervals with the connecting rod 300. When the crank 200 and the connecting rod 300 are in transmission engagement, the second connecting portion 230 will not contact the connecting rod 300. Thus, the first connecting portion 210 and the second connecting portion 230, which are connected by a bend through the transition portion 220, can ensure that the contact area between the crank 200 and the connecting rod 300 is reduced. This reduces the friction between the two when the crank 200 and the connecting rod 300 are in transmission engagement, thereby reducing the vibration caused by friction. This improves the problem of abnormal noise that is easy to occur when the sweeping device 010 is used, and enhances the user experience.

[0093] Please refer to Figure 7The first connecting part 210 includes a first positioning platform 211 and a first drive shaft 212. The first positioning platform 211 is connected to the transition part 220 at an angle. The first drive shaft 212 is connected to the first positioning platform 211 and is connected to the connecting rod 300 in a transmission connection. In this way, the reliability of the transmission connection between the crank 200 and the connecting rod 300 is ensured, so that the crank 200 can be used to ensure the reliable transmission connection between the motor 120 and the connecting rod 300, or to ensure the reliable transmission connection between the connecting rod 300 and the sweeping blade 110, thereby ensuring the reliability of driving the sweeping blade 110 to rotate to adjust the air outlet direction.

[0094] The transmission connection method between the first drive shaft 212 and the connecting rod 300 can be selected according to the needs; please refer to [the relevant documentation]. Figure 7 , Figure 10 and Figure 11 In this embodiment, the first drive shaft 212 includes a plug-in post 214 and a limiting part 215. One end of the plug-in post 214 is connected to the first positioning platform 211, and the other end of the plug-in post 214 is connected to the limiting part 215. The connecting rod 300 is provided with an assembly hole 301, and the first drive shaft 212 is plugged into the assembly hole 301. Specifically, the plug-in post 214 is tightly plugged into the assembly hole 301, and the limiting part 215 abuts against the connecting rod 300 to prevent the first drive shaft 212 from separating from the assembly hole 301.

[0095] Furthermore, the limiting part 215 includes two limiting blocks 216, both of which are connected to the insertion post 214 and are spaced apart to form a deformation groove 217. When the first drive shaft 212 is inserted into the assembly hole 301, the two limiting blocks 216 are first inserted into the assembly hole 301 and both of them are in contact with the hole wall of the assembly hole 301, so that the width of the deformation groove 217 is reduced, that is, the distance between the two limiting blocks 216 is reduced. When the two limiting blocks 216 pass through the assembly hole 301, the insertion post 214 is tightly inserted into the assembly hole 301, and the two limiting blocks 216 separate from each other, that is, the distance between them increases, so that the two limiting blocks 216 are reset. Both limiting blocks 216 abut against the connecting rod 300 so that the first drive shaft 212 will not disengage from the assembly hole 301.

[0096] It should be understood that in other embodiments, the first drive shaft 212 and the connecting rod 300 can also be connected by fasteners such as bolts, which is not specifically limited here.

[0097] Please refer to Figure 7 and Figure 9The second connecting part 230 includes a second positioning platform 231 and a second drive shaft 232. The second positioning platform 231 is connected to the transition part 220 at an angle, and the second drive shaft 232 is connected to the motor 120 or the sweeping blade 110 for transmission. The second positioning platform 231 and the connecting rod 300 are distributed at intervals along the extension direction of the rotation axis c of the sweeping blade 110. By connecting the second positioning platform 231 to the transition portion 220 at an angle, it can be ensured that the first connecting portion 210 and the second connecting portion 230 are reliably connected in a bent shape through the transition portion 220. In the extension direction of the rotation axis c of the sweeping blade 110, the second positioning platform 231 and the connecting rod 300 are distributed at intervals, which ensures that the second positioning platform 231 does not contact the connecting rod 300 when the crank 200 and the connecting rod 300 are engaged in transmission. In particular, the second positioning platform 231 of the crank 200 that drives the motor 120 and the connecting rod 300 will not contact the connecting rod 300, that is, it ensures that the contact area between the crank 200 and the connecting rod 300 is reduced, which helps to reduce the friction between the two and reduce the vibration caused by friction, so as to improve the problem of abnormal noise that is easy to occur when the sweeping device 010 is used and improve the user experience.

[0098] It should be noted that, please refer to Figure 7 The connection between the first positioning platform 211, the second positioning platform 231, and the transition portion 220 at an angle can mean that the extension surface of the first positioning platform 211 is distributed at an angle α with the extension surface of the transition portion 220, and the extension surface of the second positioning platform 231 is distributed at an angle b with the extension surface of the transition portion 220. It should also be noted that the angles α and β can be set as needed, for example, 110°, 120°, 135°, etc., and are not specifically limited here.

[0099] In this embodiment, the extension surfaces of the first positioning platform 211 and the second positioning platform 231 are distributed in parallel, and the transition portion 220 is inclined relative to the first positioning platform 211. In this way, along the extension direction of the rotation axis c of the sweeping blade 110, the transition portion 220 and the connecting rod 300 are distributed at intervals. That is, when the crank 200 and the connecting rod 300 swing relative to each other, the transition portion 220 and the connecting rod 300 do not contact each other, so as to further ensure that the contact area between the crank 200 and the connecting rod 300 is reduced, which helps to reduce the friction between the two and reduce the vibration caused by friction, so as to improve the problem of abnormal noise easily generated during the use of the sweeping device 010 and improve the user experience.

[0100] It should also be noted that the bent shape of the crank 200 makes the connection between the crank 200 and the sweeping blade 110 more compact, which helps to reduce the gap between the crank 200 and the sweeping blade 110. Similarly, it also makes the connection between the crank 200 and the connecting rod 300 more compact, and the connection between the crank 200 and the motor 120 more compact, which helps to save material input during the production and assembly of the sweeping device 010.

[0101] The transmission connection method between the second drive shaft 232 and the motor 120 can be selected as needed. For example, the second drive shaft 232 is provided with a plug hole, and the output shaft of the motor 120 is tightly plugged into the plug hole to form an interference fit; or, the output shaft of the motor 120 is welded or snapped to the second drive shaft 232, etc., without specific limitations here.

[0102] The transmission connection between the second drive shaft 232 and the sweeping blade 110 can be selected as needed, and is similar to the transmission connection between the second drive shaft 232 and the output shaft of the motor 120, so it will not be described in detail here.

[0103] In this embodiment, please refer to Figure 7 The crank 200 also includes a limiting member 202, which is disposed on the crank body 201. Specifically, the limiting member 202 is disposed on the second drive shaft 232. The connecting rod 300 is connected to the motor 120 through the crank body 201 of one of the cranks 200, and the corresponding limiting member 202 is used to limit the angle at which the motor 120 drives the crank 200 to swing. The sweeping blade 110 is connected to the connecting rod 300 through the crank body 201 of the other crank 200, and the corresponding limiting member 202 is used to limit the swing angle of the sweeping blade 110.

[0104] The limiting member 202 of the crank 200, which drives the motor 120 and connecting rod 300, can limit the swing angle of the crank 200 driven by the motor 120. This allows for indirect control of the swing angle of the sweeping blades 110 when the motor 120, connecting rod 300, and crank 200 work together to drive the sweeping blades 110 to swing. Conversely, the limiting member 202 of the crank 200, which drives the connecting rod 300 and sweeping blades 110, can limit the swing angle of the sweeping blades 110. This allows for direct limitation of the swing angle of the sweeping blades 110 when the motor 120, connecting rod 300, and crank 200 work together to drive the sweeping blades 110 to swing. Thus, the limiting member 202 reliably controls the swing angle of the sweeping blades 110, improves the regularity of the swing, helps mitigate energy waste, and contributes to energy savings in the air conditioner.

[0105] Please refer to Figure 11 ,Figure 12 and Figure 13 The sweeping device 010 also includes a motor cover 130, which is disposed on the air outlet frame 100. The motor cover 130 is provided with a first limiting stop 140. The limiting member 202 of the crank 200 of the transmission connecting rod 300 and the motor 120 can abut against the first limiting stop 140 to limit the swing angle of the crank 200 driven by the motor 120. The cooperation between the limiting member 202 and the first limiting stop 140 can reliably limit the swing angle of the crank 200 driven by the motor 120, thereby limiting the swing amplitude of the connecting rod 300. This indirectly controls the swing angle of the sweeping blade 110, which is transmitted to the connecting rod 300, thus ensuring the regularity of the swing of the sweeping blade 110. This helps to improve the problem of kinetic energy waste and achieve energy saving.

[0106] Further, please refer to Figure 13 The motor cover 130 is provided with a first clearance hole 131. The wall of the first clearance hole 131 is provided with a first limiting stop 140. The second drive shaft 232 of the transmission connecting rod 300 and the crank 200 of the motor 120 passes through the first clearance hole 131 and is connected to the output shaft of the motor 120. The limiting stop 202 can abut against the first limiting stop 140. In this way, the swing angle of the crank 200 driven by the motor 120 can be reliably limited, thereby indirectly limiting the swing angle of the sweeping blade 110.

[0107] Furthermore, the first limiting stop 140 has a first abutting surface 141 and abutting surface 142. One end of the first abutting surface 141 and one end of the second abutting surface 142 are both connected to the wall of the first clearance hole 131. The other ends of the first abutting surface 141 and the second abutting surface 142 extend away from the wall of the first clearance hole 131, and the distance between the first abutting surface 141 and the second abutting surface 142 gradually decreases from the end near the wall of the first clearance hole 131 to the end away from the wall of the first clearance hole 131. When the motor 120 drives the crank 200 along... Figure 13 When the crank 200 swings clockwise, the limiting member 202 can abut against the first contact surface 141. When the motor 120 drives the crank 200 to move clockwise... Figure 13When the air swings counterclockwise, the limiting member 202 can abut against the second contact surface 142. Thus, when adjusting the airflow direction using the sweeping device 010, when the motor 120 drives the crank 200 to swing until the limiting member 202 abuts against the first contact surface 141, the motor 120 can drive the crank 200 to swing in the opposite direction. When the limiting member 202 abuts against the second contact surface 142, the motor 120 can again drive the crank 200 to swing in the opposite direction, and this cycle repeats. By controlling the crank 200 to form a regular reciprocating swing, the connecting rod 300 can form a regular reciprocating swing, which in turn drives the sweeping blades 110 to form a regular swing. This allows for more regular control of the sweeping direction adjustment, which helps to improve the problem of wasted kinetic energy and saves energy in the air conditioner.

[0108] It should be noted that the way the motor cover 130 is set on the air outlet frame 100 can be selected as needed. For example, the motor cover 130 can be set on the air outlet frame 100 by bolts or other fasteners, or the motor cover 130 can be snapped onto the air outlet frame 100. No specific limitation is made here.

[0109] Alternatively, please refer to Figure 13 The first limiting stop 140 also includes a first arc-shaped concave surface 143. The end of the first abutting surface 141 away from the wall of the first clearance hole 131 and the end of the second abutting surface 142 away from the wall of the first clearance hole 131 are both connected to the first arc-shaped concave surface 143. The first drive shaft 212 is clearance-fitted with the first arc-shaped concave surface 143, meaning there is a certain gap between them to ensure that the rotation of the first drive shaft 212 is not interfered with by the first limiting stop 140. Of course, in other embodiments, the end of the first abutting surface 141 away from the wall of the first clearance hole 131 is connected to the end of the second abutting surface 142 away from the wall of the first clearance hole 131.

[0110] It should be understood that in other embodiments, the first limiting stop 140 is disposed on the air outlet frame 100, and the limiting member 202 of the crank 200 that drives the motor 120 and the connecting rod 300 can abut against the first limiting stop 140 to limit the angle at which the motor 120 drives the crank 200 to swing.

[0111] In this embodiment, please refer to Figure 13The air outlet frame 100 is provided with a second limiting stop 150. The limiting member 202 of the crank 200 of the transmission connecting rod 300 and the sweeping blade 110 can abut against the second limiting stop 150 to limit the swing angle of the sweeping blade 110. The cooperation of the limiting member 202 and the second limiting stop 150 can reliably limit the swing angle of the crank 200 driving the sweeping blade 110, ensuring the regularity of the swing of the sweeping blade 110, which is conducive to improving the problem of kinetic energy waste and achieving energy saving. Moreover, when the sweeping blade 110 of the sweeping device 010 swings, the limiting member 202 of the crank 200 that drives the motor 120 to drive the swing angle of the crank 200 is limited by the transmission connection between the motor 120 and the connecting rod 300, so as to indirectly control the swing angle of the sweeping blade 110. At the same time, the limiting member 202 of the crank 200 that drives the sweeping blade 110 to directly limit the swing angle of the sweeping blade 110 is also used to control the swing angle of the sweeping blade 110 more reliably, ensuring the regularity of the swing of the sweeping blade 110, which is conducive to improving the problem of kinetic energy waste and achieving energy saving of the air conditioner.

[0112] The air outlet frame 100 is provided with a second clearance hole 101, and a second limiting stop 150 is provided on the wall of the second clearance hole 101. The second drive shaft 232 of the crank 200 of the transmission connecting rod 300 and the sweeping blade 110 passes through the second clearance hole 101 and drives the sweeping blade 110. The limiting stop 202 is located inside the second clearance hole 101 and can abut against the second limiting stop 150. In this way, the rotation angle of the sweeping blade 110 can be reliably limited by the cooperation of the limiting stop 202 and the second limiting stop 150.

[0113] Furthermore, the second limiting stop 150 has a first limiting surface 151 and a second limiting surface 152. One end of the first limiting surface 151 and one end of the second limiting surface 152 are connected to the wall of the second clearance hole 101. The other end of the first limiting surface 151 and the other end of the second limiting surface 152 extend away from the wall of the second clearance hole 101. The distance between the first limiting surface 151 and the second limiting surface 152 gradually decreases from the end near the wall of the second clearance hole 101 to the end away from the wall of the second clearance hole 101. The limiting member 202 of the crank 200 of the transmission connecting rod 300 and the sweeping blade 110 can abut against the first limiting surface 151 or the second limiting surface 152. Through the setting of the first limiting surface 151 and the second limiting surface 152, the angle control of the reciprocating swing of the sweeping blade 110 can be reliably ensured, thereby achieving better control of the air outlet direction, which is conducive to improving the problem of kinetic energy waste and realizing energy saving.

[0114] Furthermore, please refer to Figure 14The second limiting stop 150 also includes a second arc-shaped concave surface 153. The ends of the first limiting surface 151 and the second limiting surface 152 that are away from the wall of the second clearance hole 101 are both connected to the second arc-shaped concave surface 153. The second arc-shaped concave surface 153 is in clearance fit with the second drive shaft 232, meaning there is a certain gap between them to prevent the second limiting stop 150 from interfering with the rotation of the second drive shaft 232. Alternatively, in other embodiments, the end of the first limiting surface 151 away from the wall of the second clearance hole 101 is connected to the end of the second limiting surface 152 that is away from the wall of the second clearance hole 101.

[0115] It should be noted that when the connecting rod 300 drives the crank 200, which is connected to the sweeping blade 110, along... Figure 13 When the crank 200 swings counterclockwise until the limiting member 202 abuts against the first limiting surface 151, the crank 200 moves along... Figure 13 The crank arm swings counterclockwise to its limit position, at which point crank 200 can no longer move along... Figure 13 The connecting rod 300 swings counterclockwise, and can only drive the crank 200 along the direction of the rotation. Figure 13 The crank oscillates clockwise, when the crank 200... Figure 13 When the crank 200 swings clockwise until the limiting member 202 abuts against the second limiting surface 152, the crank 200 moves along... Figure 13 The crank arm swings clockwise to its limit position, at which point crank 200 can no longer move... Figure 13 When the crank swings clockwise, connecting rod 300 can only drive crank 200 again. Figure 13 The crank swings counterclockwise, and the connecting rod 300 drives the crank 200 to move along the same direction. Figure 14 The crank 200 swings counterclockwise and cycles in the manner described above to drive the crank 200 to swing back and forth, and to ensure that the sweeping blades 110 swing back and forth more regularly.

[0116] The angle between the first limiting surface 151 and the second limiting surface 152 around the rotation axis of the sweeping blade 110 can be set as needed; in a preferred embodiment, please refer to... Figure 14 The angle β between the first limiting surface 151 and the second limiting surface 152 around the rotation axis of the sweeping blade 110 is 280°-285°. Setting the angle β between the first limiting surface 151 and the second limiting surface 152 around the rotation axis of the sweeping blade 110 to 280°-285° ensures that the sweeping blade 110 has a sufficiently large swing range, thereby obtaining a wider sweeping area and ensuring good air outlet performance.

[0117] Please refer to Figure 15In this embodiment, the angle β between the first limiting surface 151 and the second limiting surface 152 around the rotation axis of the sweeping blade 110 is 283°, so that the sweeping blade 110 can swing within a swing angle range of 283°, thereby obtaining a better airflow direction. Of course, in other embodiments, the angle between the first limiting surface 151 and the second limiting surface 152 around the rotation axis of the sweeping blade 110 can also be 275°, 280°, 282°, 288°, etc., and is not specifically limited here.

[0118] In this embodiment, the first positioning platform 211 is in direct surface contact with the connecting rod 300, that is, the side of the first positioning platform 211 connected to the first drive shaft 212 is in surface contact with the connecting rod 300; in this way, the possibility of vibration when the sweeping blade 110 rotates can be further reduced.

[0119] Please refer to Figure 16 , Figure 17 and Figure 15 In some embodiments, the crank 200 further includes a first positioning rib 213, which is disposed on the crank body 201 and contacts the connecting rod 300. In this way, the contact area between the crank 200 and the connecting rod 300 is reduced by the placement of the first positioning rib 213, thereby reducing the friction between the crank 200 and the connecting rod 300 and helping to improve the problem of abnormal noise.

[0120] Furthermore, the first positioning rib 213 is disposed on the first positioning platform 211; specifically, the first positioning rib 213 and the first drive shaft 212 are disposed on the same side of the first positioning platform 211; so as to effectively reduce the contact area between the crank 200 and the connecting rod 300, reduce the friction between the crank 200 and the connecting rod 300, and help improve the problem of abnormal noise.

[0121] In other embodiments, the first positioning rib 213 is disposed on the connecting rod 300 and contacts the crank 200, that is, the first positioning rib 213 contacts the first positioning platform 211, so as to reduce the contact area between the crank 200 and the connecting rod 300 by the first positioning rib 213, reduce the friction between the two, and help to improve the problem of abnormal noise.

[0122] In some implementation methods, please refer to Figure 16 , Figure 17 and Figure 18The crank 200 also includes a second positioning rib 233, which is disposed on the crank body 201. The second positioning rib 233 contacts the motor cover 130 or the air outlet frame 100. Specifically, the second positioning rib 233 of the crank 200 that drives the motor 120 and the connecting rod 300 contacts the motor cover 130, and the second positioning rib 233 of the crank 200 that drives the sweeping blade 110 and the connecting rod 300 contacts the air outlet frame 100. By setting the second positioning rib 233, the contact area between the motor cover 130 and the corresponding crank 200 is reduced, or the contact area between the air outlet frame 100 and the corresponding crank 200 is reduced, thereby reducing friction and improving the problem of abnormal noise.

[0123] Furthermore, the second positioning rib 233 and the second drive shaft 232 are disposed on the same side of the second positioning platform 231, so as to effectively reduce the contact area between the crank 200 and the motor cover 130, or reduce the contact area between the crank 200 and the air outlet frame 100, which helps to reduce friction and improve the problem of abnormal noise.

[0124] In some other embodiments, the motor cover 130 or the air outlet frame 100 is provided with a second positioning rib 233, which contacts the crank body 201. In this way, the contact area between the motor cover 130 and the corresponding crank 200 or the air outlet frame 100 and the corresponding crank 200 can be reduced by the provision of the second positioning rib 233, thereby reducing friction and improving the problem of abnormal noise.

[0125] It should be understood that in some other embodiments, the second positioning platform 231 does not have a second positioning rib 233, and the second positioning platform 231 is in contact with the motor cover 130 or the air outlet frame 100, which helps to reduce the possibility of vibration when the sweeping blades 110 rotate.

[0126] Please refer to Figure 19 and ​ In some embodiments, the air outlet frame 100 is provided with a positioning groove 160, and the second positioning rib 233 is movably embedded in the positioning groove 160.

[0127] The cooperation between the second positioning rib 233 and the positioning groove 160 ensures that the crank 200 has good coaxiality, enabling the crank 200 to swing stably and reliably. Moreover, the positioning groove 160 can further reduce friction by adding lubricating oil to it, thereby ensuring the smoothness of the crank 200's swing and reducing abnormal noise.

[0128] Furthermore, the positioning groove 160 extends in a ring around the rotation axis of the sweeping blade 110, and the second positioning rib 233 is embedded in the positioning groove 160 and can rotate around the rotation axis of the sweeping blade 110 as the crank 200 swings. In this way, the crank 200 can be ensured to have coaxiality, so that the crank 200 swings stably and reliably.

[0129] In this embodiment, the second positioning rib 233 is a closed annular rib; of course, in other embodiments, the second positioning rib 233 includes multiple ribs, which are arranged sequentially and at intervals around the rotation axis of the sweeping blade 110 on the second positioning platform 231.

[0130] Optionally, the crank 200 is integrally formed, that is, the first drive shaft 212, the first positioning platform 211, the transition portion 220, the second positioning platform 231, the second drive shaft 232, and the limiting member 202 are all integrally formed. Further, the first positioning rib 213 and the first positioning platform 211 can be integrally formed, and the second positioning rib 233 and the second positioning platform 231 can be integrally formed.

[0131] In this embodiment, the air conditioner can adjust the air outlet direction using the air sweeping device 010. When the air sweeping device 010 is working, the motor 120 drives the crank 200 connected to it to swing, and the crank 200 drives the connecting rod 300 to swing. The connecting rod 300 drives the crank 200 connected to the air sweeping blade 110 to swing, thereby driving the air sweeping blade 110 to rotate.

[0132] In summary, the air sweeping device 010 of the air conditioner of the present invention can make the sweeping blade 110 rotate smoothly through the transmission cooperation of the crank 200 and the connecting rod 300, thereby reducing the vibration of the sweeping blade 110 and improving the user experience.

[0133] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
