[0045] Embodiment 1

[0046] The embodiment provides a kind of sweeping wind device, such as Figures 1-17As shown, the wind sweeping device includes a blade assembly 1, a drive assembly 2, a swing assembly 3 and a rotating assembly 4. The blade assembly 1 is connected to the swing assembly 3, and the blade assembly 1 is also connected to the rotating assembly 4. The drive assembly 2 is connected to the swing assembly 3 to drive the blade assembly 1 to rotate to achieve wind sweeping in different directions. The drive assembly 2 is also connected to the rotating assembly 4 to drive the blade assembly 1 to rotate so as to be close to the inner wall of the air duct or to have an angle with the inner wall of the air duct.

[0047] In this embodiment, the blade assembly 1 is arranged at the air outlet and guides the direction of the airflow by swinging left and right. The driving assembly 2 is connected to the swing assembly 3 and the rotating assembly 4 respectively, and is used to drive the swing assembly 3 and the rotating assembly 4 to work.

[0048] The swing assembly 3 is connected to the blade assembly 1. Under the action of the drive assembly 2, the swing assembly 3 can drive the blade assembly 1 to rotate in a first direction to achieve wind sweeping in different directions. To more clearly explain the first direction, it is assumed that the blade assembly 1 includes multiple blades, each of which can rotate in the first direction. The rotation of the blades in the first direction means that the blades can rotate about their own axes, so as to adjust the angle of the wind blown out from between adjacent blades.

[0049] The rotating assembly 4 is connected to the blade assembly 1. Under the action of the driving assembly 2, the rotating assembly 4 can drive the blade assembly 1 to rotate in the second direction. On the one hand, it makes the blade assembly 1 close to the inner wall of the air duct, that is, it leans against the inner wall of the air duct. On the other hand, it can also make the blade assembly 1 located at the air outlet to adjust the wind sweeping direction. Each blade in the blade assembly 1 can rotate in the second direction. In order to explain the second direction more clearly, it is assumed that the air duct is formed by a first plate-like structure and a second plate-like structure, that is, the first plate-like structure and the second plate-like structure are arranged relative to each other, and an air duct is formed between the two, and the wind sweeping device is arranged in the air duct near the air outlet. Among them, the rotation of the blade in the second direction means that the blade can rotate toward the first plate-like structure or the second plate-like structure. Assuming that when the blade is tightly attached to the second plate-like structure, that is, it is tilted towards the inner wall of the air duct as mentioned above, the blade has the following two states under the action of the rotating component 4: the first state is that the entire blade rotates toward the second plate-like structure until it is tightly attached to the second plate-like structure. At this time, the blade is hidden in the air duct, reducing the obstruction to the air outlet; when it needs to be converted to the second state, the entire blade rotates toward the first plate-like structure, and stops rotating when it rotates to the middle of the first plate structure and the second plate structure. At this time, the blade assembly is in working state, and its wind sweeping angle can be adjusted through the swing component 3.

[0050] The wind sweeping device provided in this embodiment, when the air conditioner needs the left and right wind sweeping function, the blade assembly 1 can be located at the air outlet and swing to sweep the wind in the left and right directions, such asFigures 5-12 The diagram is a structural diagram of the blade assembly 1 at different angles under the action of the swing assembly 3 in the wind sweeping device; when the left and right wind sweeping function is not needed, the blade assembly 1 can be tilted in the air duct for hiding, such as Figure 13 and Figure 14 As shown, the obstruction to the air outlet is reduced and the air outlet volume is increased. In addition, the air sweeping device provided in this embodiment does not damage the structure of the air duct itself, and thus does not affect the performance of the air conditioner.

[0051] In a specific embodiment, Figures 2-4 As shown, the swing assembly 3 includes a first driving wheel 31, a first driven wheel 32, and a swing link 33. The first driving wheel 31 is connected to the output shaft of the drive assembly 2 and also cooperates with the first driven wheel 32. The first driven wheel 32 is connected to the swing link 33. The swing link 33 has a notch 34 for receiving the blade assembly 1. The drive assembly 2 can rotate the blade assembly 1 within the notch 34 via the first driving wheel 31 and the first driven wheel 32. The drive assembly 2 is a motor. The first driving wheel 31 is horizontally arranged and sleeved on the output shaft of the motor. It cooperates with the first driven wheel 32. The first driven wheel 32 is connected to the swing link 33, which cooperates with the blade assembly 1. Thus, when the drive assembly 2 is in operation, it drives the first driving wheel 31 to rotate, which in turn drives the first driven wheel 32 to rotate. The first driven wheel 32 drives the swing link 33 to swing, thereby causing the blade assembly 1 to rotate in a first direction.

[0052] In this embodiment, the first driving wheel 31 and the first driven wheel 32 are both arranged in a horizontal direction, and can convert the force of the driving assembly 2 into a horizontal force, thereby driving the blade assembly 1 to rotate in a first direction. When the motor rotates in the first direction, it can cause the blade assembly 1 to rotate in the first direction through the first driving wheel 31, the first driven wheel 32, and the swing link 33; when the motor rotates in the second direction, it can cause the blade assembly 1 to rotate in the second direction through the first driving wheel 31, the first driven wheel 32, and the swing link 33, thereby adjusting the blade assembly 1 to meet user needs.

[0053] In a specific embodiment, a portion of the outer ring of the first driving wheel 31 has a first tooth structure, so that the driving assembly 2 can drive the blade assembly 1 to rotate in the notch 34 at intervals.

[0054] The first driving wheel 31 is arranged horizontally, and the first tooth structure is arranged on the outer ring. In this embodiment, the first tooth structure is only arranged at a certain position in the outer ring of the first driving wheel 31. For example, the first driving wheel 31 is divided into a left half and a right half, and the first tooth structure is only arranged on the outer ring of the left half or the right half. This arrangement is to achieve the intermittent operation of the swing component 3.

[0055] More specifically, in one state, the first tooth structure on the first driving wheel 31 is engaged with the first driven wheel 32. In this case, the driving assembly 2 can drive the swing assembly 3 to operate to adjust the air outlet angle of the blade assembly 1. In another state, the first tooth structure on the first driving wheel 31 is misaligned with the first driven wheel 32. In this case, the driving assembly 2 cannot drive the swing assembly 3 to operate. However, in this case, the rotating assembly 4 can operate to drive the blade assembly 1 to rotate so as to achieve close contact with the inner wall of the air duct or to form an angle with the inner wall of the air duct. In other words, the reason why the first tooth structure does not cover the entire outer ring of the first driving wheel 31 is to achieve intermittent operation of the swing assembly 3 and the rotating assembly 4. Because it is meaningless for the swing assembly 3 and the rotating assembly 4 to operate simultaneously, for example, when air sweeping is no longer required, the blade assembly 1 does not need to rotate while the rotating assembly 4 makes the blade assembly 1 close to the air duct.

[0056] In a specific embodiment, the swing assembly 3 further includes a swing-linking rod 35, one end of which is fixed to the first driven wheel 32. The other end of the swing-linking rod 35 has a first spherical structure 36. The first spherical structure 36 is disposed within a first hole 37 of the swing link 33, and the diameter of the first spherical structure 36 is greater than the inner diameter of the first hole 37. The swing-linking rod 35 is primarily used to link the first driven wheel 32 and the swing link 33 together.

[0057] The swing-link linkage 35 includes a first horizontal rod and a first vertical rod. One end of the first horizontal rod is fixed to the first driven wheel 32, and the other end of the first horizontal rod is connected to one end of the first vertical rod. The other end of the first vertical rod has a first spherical structure 36, which engages with a first hole 37 in the swing link 33. The diameter of the first spherical structure 36 is larger than the inner diameter of the first hole 37, so that the first spherical structure 36 does not fall out of the first hole 37. In addition, the top of the first spherical structure 36 has an opening, which facilitates the installation of the first spherical structure 36 after the other end of the first vertical rod passes through the first hole 37.

[0058] In a specific embodiment, Figures 2-4As shown, the rotating assembly 4 comprises a second driving wheel 41, a second driven wheel 42 and a rotating link 43, the second driving wheel 41 is connected with the output shaft of the driving assembly 2, the second driving wheel 41 is also matched with the second driven wheel 42, the second driven wheel 42 is arranged at the end of the rotating link 43, the rotating link 43 has a through hole 44, the vane assembly 1 is matched with the through hole 44; the driving assembly 2 can drive the rotating link 43 and the vane assembly 1 to rotate together through the second driving wheel 41 and the second driven wheel 42. Wherein, the driving assembly 2 is a motor. The second driving wheel 41 is horizontally arranged and sleeved on the output shaft of the motor, and is matched with the vertically arranged second driven wheel 42, and the second driven wheel 42 is arranged at the end of the rotating link 43. In this way, when the driving assembly 2 works, it drives the second driving wheel 41 to rotate, the second driving wheel 41 drives the second driven wheel 42 to rotate, the second driven wheel 42 drives the rotating link 43 to rotate, and the vane assembly 1 is fixed in the through hole 44 of the rotating link 43, so the rotating link 43 drives the vane assembly 1 to rotate together.

[0059] In the embodiment, since the second driven wheel 42 connected with the rotating link 43 is vertically arranged, it can drive the vane assembly 1 to rotate in the second direction. When the motor rotates in the first direction, it can make the vane assembly 1 closely adhere to the inner wall of the air duct through the second driving wheel 41, the second driven wheel 42 and the rotating link 43; when the motor rotates in the second direction, it can make the vane assembly 1 be located at the air outlet of the air duct to realize the air sweeping adjustment through the second driving wheel 41, the second driven wheel 42 and the rotating link 43.

[0060] In addition, the rotating link 43 also has a fixed rod 45, and the first driven wheel 32 is sleeved on the fixed rod 45. In the embodiment, the first driven wheel 32 of the swinging assembly 3 and the rotating link 43 of the rotating assembly 4 are associated together through the fixed rod 45, so that when the rotating assembly 4 works, for example, when the rotating assembly 4 needs to closely adhere to the inner wall of the air duct, it can also drive the first driven wheel 32 and the swinging link 33 to fall on the inner wall of the air duct, further avoiding the loss of air volume.

[0061] In specific embodiments, part of the outer ring of the second driving wheel 41 has a second tooth structure, so that the driving assembly 2 can drive the vane assembly 1 to rotate in the air outlet direction at intervals.

[0062] The second driving wheel 41 is horizontally arranged, and the second tooth structure is arranged on the outer ring. In the embodiment, only part of the outer ring of the second driving wheel 41 is provided with the second tooth structure, for example, the second driving wheel 41 is divided into left half and right half, and the second tooth structure is arranged on the outer ring of only the left half or the right half. This arrangement is to realize the interval work of the rotating assembly 4.

[0063] More specifically, in one state, the second tooth structure on the second driving wheel 41 is just engaged with the second driven wheel 42. In this case, the driving assembly 2 can drive the rotating assembly 4 to operate to adjust the blade assembly 1. In the other state, the second tooth structure on the second driving wheel 41 is just offset from the second driven wheel 42. At this time, the driving assembly 2 cannot drive the rotating assembly 4 to operate. However, in this case, the swing assembly 3 can operate, which is used to drive the blade assembly 1 to rotate to adjust the wind sweep angle. In other words, the reason why the second tooth structure does not cover the entire outer ring of the second driving wheel 41 is to achieve intermittent operation of the swing assembly 3 and the rotating assembly 4, because it does not make sense for the swing assembly 3 and the rotating assembly 4 to operate simultaneously.

[0064] In a specific embodiment, the first driving wheel 31 and the second driving wheel 41 are arranged vertically and rotate together with the drive assembly 2. The first tooth structure and the second tooth structure are staggered vertically, so that the swing assembly 3 and the rotating assembly 4 operate alternately. The air sweeping device provided in this embodiment only requires a single drive assembly 2 to drive the swing assembly 3 and the rotating assembly 4.

[0065] The first and second tooth structures are staggered vertically, that is, when the first tooth structure is located on the left half of the first driving wheel 31, the second tooth structure is located on the right half of the second driving wheel 41. Because the first and second driving wheels 31, 41 rotate together with the drive assembly 2, when the first driving wheel 31 is meshed with the first driven wheel 32, there is no mating relationship between the second driving wheel 41 and the second driven wheel 42. Similarly, when the second driving wheel 41 is meshed with the second driven wheel 42, there is no mating relationship between the first driving wheel 31 and the first driven wheel 32. In other words, when the oscillating assembly 3 is operating, the rotating assembly 4 is not operating, and when the rotating assembly 4 is operating, the oscillating assembly 3 is not operating.

[0066] In a specific embodiment, Figures 2-4 As shown, the blade assembly 1 includes a plurality of blades, which are connected to the swing assembly 3 and the rotating assembly 4. The blade includes a blade body 11, to which a fixed shaft 12 is connected. The fixed shaft 12 is connected to the swing assembly 3 via a connecting rod 13, and the fixed shaft 12 is also connected to the rotating assembly 4. The lower end of the fixed shaft 12 has a step structure 15. After the fixed shaft 12 is engaged with the through hole 44 on the rotating connecting rod 43, the top end of the through hole 44 is stuck below the step structure 15.

[0067] A plurality of blades are arranged at the air outlet for realizing the air sweeping. The blade body 11 is a circular or elliptical sheet structure, at the bottom of which, a fixed shaft 12 is connected, the fixed shaft 12 includes a first part close to the blade body 11 and a second part away from the blade body 11, wherein the diameter of the first part is larger than that of the second part. A part is mainly used for realizing the connection with the swing assembly 3, specifically, at one side of the first part, an extension connecting rod 13 is connected, the end of the connecting rod 13 is connected with the swing connecting rod 33, and the first part is also located in the notch 34 of the swing connecting rod 33. The second part is mainly used for realizing the connection with the rotating assembly 4, specifically, since the diameter of the first part is larger than that of the second part, a step structure 15 is formed at the connection between the first part and the second part, after the second part is inserted into the through hole 44, the top of the through hole just abuts against the step structure 15, and then the pin is fixed on the second part below the through hole 44, so as to realize the connection between the fixed shaft 12 and the rotating connecting rod 43.

[0068] In a specific embodiment, the end of the connecting rod 13 has a second spherical structure 14, the swing connecting rod 33 has a second hole 38, and the diameter of the second spherical structure 14 is larger than the inner diameter of the second hole 38, so that the second spherical structure 14 can be clamped in the second hole 38, avoiding the second spherical structure 14 from being separated from the second hole 38.

[0069] In addition, in the air sweeping device provided in the embodiment, the shape of the blade body 11 matches the shape of the inner wall of the air duct, for example, if the air duct is an arc-shaped curve, the shape of the blade body 11 can be correspondingly set as a curved shape to adapt to the position space in the folded state.

[0072] The air conditioner further comprises a shell 5, the bottom end of the shell 5 is bent towards the air conditioner to form the air outlet, in addition, in order to realize the fixation of the air sweeping device, a fixing clamp 6 is arranged at the bent shell part, and the rotating connecting rod 43 of the rotating assembly 4 is movably arranged in the fixing clamp 6.

[0073] When the air sweeping is not needed, the air sweeping device is in the first state, that is, abutting against the inner wall of the air duct, so as to reduce the obstruction to the air outlet and increase the air volume. When the air sweeping is needed, the air sweeping device is in the second state, that is, having an included angle with the inner wall of the air duct, at this time, the angle of the air sweeping can be adjusted through the swing assembly 3.
