[0051] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0052] The fan assembly 100 according to an embodiment of the present invention will be described below with reference to the drawings.

[0053] As Figures 2 - 5 shown, the fan assembly 100 according to an embodiment of the present invention includes a fixed support 1, a drive motor 2, a wind wheel 3, a static blade assembly 4, a fixing member 5 and a drive mechanism 6.

[0054] Specifically, as Figure 2 shown, the drive motor 2 is provided on the fixed support 1, the wind wheel 3 is connected to the output shaft of the drive motor 2, the drive motor 2 can drive the wind wheel 3 to rotate, and the wind wheel 3 can drive the air flow to flow. Along the air flow direction of the wind wheel 3, the static blade assembly 4 is located downstream of the wind wheel 3, and the air flow sent out by the wind wheel 3 can pass through the static blade assembly 4. Under the action of the static blades 43 of the static blade assembly 4, the air flow can have a certain degree of swirl, making the wind blown by the fan assembly 100 closer to natural wind.

[0055] When the wind wheel 3 rotates, the moving air flow generated by the wind wheel 3 can drive the static blade member 4 to rotate. When the static blade member 4 rotates, it can increase the vorticity of the moving air flow. Among them, when the moving air flow generated by the wind wheel 3 drives the static blade member 4 to rotate during the rotation of the wind wheel 3, the rotation direction of the static blade member 4 can be the same as the rotation direction of the wind wheel 3, or the rotation direction of the static blade member 4 can be opposite to the rotation direction of the wind wheel 3. The rotation direction of the static blade member 4 can be determined according to the inclination direction of the static blades 43 on the static blade member 4.

[0056] As Figure 2 shown, the fixing member 5 is arranged on the fixing bracket 1, the driving mechanism 6 is arranged on the fixing bracket 1, and the driving mechanism 6 is connected to the static blade member 4 to drive the static blade member 4 to move between a first position and a second position. The first position and the second position are spaced apart in the air flow direction. Among them, in the first position, the static blade member 4 contacts the fixing member 5, the static blade member 4 is stationary relative to the fixing bracket 1, and there is a frictional force between the static blade member 4 and the fixing member 5. The frictional force forms a resistance to the rotation of the static blade member 4, and the resistance inhibits the rotation of the static blade member 4; in the second position, the static blade member 4 is spaced apart from the fixing member 5. When the wind wheel 3 rotates, the moving air flow generated by the wind wheel 3 can drive the static blade member 4 to rotate relative to the fixing bracket 1. There is no frictional resistance between the static blade member 4 and the fixing member 5. The static blade member 4 can rotate under the action of the moving air flow generated by the wind wheel 3. At the same time, the static blade member 4131 disturbs the air flow, which can increase the vorticity of the moving air flow, so that the outgoing air has a high vorticity and multi-directionality, and thus a swirling wind feeling can be obtained.

[0057] When the fan assembly 100 works, the driving mechanism 6 can be used to drive the static blade member 4 to be in the first position. Due to the existence of frictional resistance, the static blade member 4 does not rotate. The static blade member 4 can disperse the wind sent out by the wind wheel 3, improving the comfort of the user; or the driving mechanism 6 can be used to drive the static blade member 4 to be in the second position. The static blade member 4 is separated from the fixing member 5. There is no frictional resistance between the static blade member 4 and the fixing member 5. The static blade member 4 rotates. The air flow sent out by the wind wheel 3 can be disturbed by the static blade member 4, increasing the vorticity of the air flow, making the outgoing air multi-directional.

[0058] Therefore, the fan assembly 100 of the present invention can drive the static blade member 4 to move between the first position and the second position through the driving mechanism 6, enabling the static blade member 4 to rotate and not rotate, thereby realizing various wind feelings and air supply forms, and improving the comfort of the user.

[0059] Optionally, the wind wheel 3 is an axial flow wind wheel 3 or a diagonal flow wind wheel 3. The axial flow wind wheel 3 or the diagonal flow wind wheel 3 can initially generate spiral air flow, further increasing the vorticity of the outgoing air, so that the swirling wind feeling is stronger and the outgoing air is more comfortable and natural.

[0060] According to the fan assembly 100 of the embodiments of the present invention, in the flowing direction of the air flow, a stator vane member 4 is provided downstream of the wind wheel 3, and the driving mechanism 6 can drive the stator vane member 4 to be movable between a first position and a second position. When the stator vane member 4 is located at the first position, the stator vane member 4 contacts the fixing member 5, and there is a frictional resistance between the stator vane member 4 and the fixing member 5, and the stator vane member 4 does not rotate. The stator vane member 4 can disperse the wind sent out by the wind wheel 3. When the stator vane member 4 is located at the second position, the stator vane member 4 is spaced apart from the fixing member 5, and the moving air flow generated by the wind wheel 3 when the wind wheel 3 rotates can drive the stator vane member 4 to rotate. Thus, a swirling wind feeling can be formed, making the air outlet more comfortable and natural, and improving the user experience. By providing the stator vane member 4 and the driving mechanism 6, the fan assembly 100 can achieve various wind feelings and air supply modes, improving the comfort of the user.

[0061] In some embodiments of the present invention, as Figures 5 - 7 shown, the fixing bracket 1 includes an annular air guiding ring 11 and a motor bracket 12. Specifically, the air guiding ring 11 is formed as a circular ring, and the air guiding ring 11 guides the air flow in the air duct, which can make the air flow concentrated. Both the wind wheel 3 and the stator vane member 4 are arranged inside the air guiding ring 11, and the wind wheel 3 and the stator vane member 4 are arranged along the axial direction of the air guiding ring 11. The first position and the second position are arranged along the axial direction of the air guiding ring 11. It can be understood that the stator vane member 4 can move along the axial direction of the air guiding ring 11 inside the air guiding ring 11. The fixing member 5 is arranged on the air guiding ring 11. When the stator vane member 4 is located at the first position, it is convenient for the stator vane member 4 to contact the fixing member 5.

[0062] The motor bracket 12 is arranged inside the air guiding ring 11 and connected to the air guiding ring 11. The driving motor 2 is arranged on the motor bracket 12. Thus, it is convenient for fixing the driving motor 2 and for the driving motor 2 to drive the wind wheel 3 to rotate. The driving mechanism 6 is arranged on the motor bracket 12. Thus, it is convenient for the driving mechanism 6 to drive the stator vane member 4 to move along the axial direction of the air guiding ring 11. Wherein the driving mechanism 6 is located between the wind wheel 3 and the stator vane member 4. Of course, the present invention is not limited thereto, and the driving mechanism 6 can also be located on the side of the stator vane member 4 far from the wind wheel 3.

[0063] Further, as Figure 5 and Figure 6As shown, the motor bracket 12 includes a mounting base 121 and a motor cover 122. The mounting base 121 is connected to the air guide ring 11, and a motor slot 1213 for placing the drive motor 2 is provided on the mounting base 121. Thus, the displacement of the drive motor 2 in the radial direction can be limited, improving the reliability of the fixation of the drive motor 2. Specifically, the mounting base 121 includes connecting arms 1212 and a mounting portion 1211. The mounting portion 1211 is provided inside the air guide ring 11, and a motor slot 1213 for mounting the drive motor 2 is provided on the mounting portion 1211. There are multiple connecting arms 1212. One end of each connecting arm 1212 is connected to the outer peripheral wall of the mounting portion 1211, and the other end of each connecting arm 1212 is connected to the inner peripheral wall of the air guide ring 11. The multiple connecting arms 1212 are spaced apart along the circumferential direction of the mounting portion 1211, preferably evenly spaced apart.

[0064] Furthermore, a limiting slot is provided on the bottom wall of the motor slot 1213, and a limiting member cooperating with the limiting slot is provided on the surface of the drive motor 2 facing the motor slot 1213. Thus, the displacement of the drive motor 2 in the circumferential direction can be limited, improving the reliability of the fixation of the drive motor 2.

[0065] As Figure 5 shown, the motor cover 122 is connected to the mounting base 121 to fix the drive motor 2 in the motor slot 1213, thereby limiting the displacement of the drive motor 2 in its axial direction and further improving the reliability of the fixation of the drive motor 2. The drive mechanism 6 is provided on the motor cover 122, facilitating the drive mechanism 6 to drive the stator vane member 4 to move along the axial direction of the air guide ring 11.

[0066] Optionally, as Figure 3 , Figure 4 and Figure 5 shown, the fan assembly 100 further includes a sealing retaining ring 7. The sealing retaining ring 7 is provided on the inner peripheral wall of the air guide ring 11. The sealing retaining ring 7 and the stator vane member 4 are arranged along the axial direction of the air guide ring 11. The sealing retaining ring 7 is located on the side of the stator vane member 4 away from the wind wheel 3. When the stator vane member 4 moves from a position close to the wind wheel 3 towards a position away from the wind wheel 3, the sealing retaining ring 7 can block the continuous movement of the stator vane member 4, preventing the stator vane member 4 from moving out of the air guide ring 11. Additionally, the sealing retaining ring 7 can seal the gap between the stator vane member 4 and the air guide ring 11, preventing air from leaking through the gap between the stator vane member 4 and the air guide ring 11. Among them, the first position can be closer to the wind wheel 3 than the second position, or the first position can be farther from the wind wheel 3 than the second position.

[0067] Optionally, as Figure 3 and Figure 8As shown, the fixing member 5 is formed as a boss on the inner peripheral wall of the air guiding ring 11, and the boss extends along the circumferential direction of the air guiding ring 11. When the stationary blade member 4 is in the first position, the outer peripheral wall of the stationary blade member 4 contacts the inner peripheral wall of the air guiding ring 11, and there is a frictional resistance between the outer peripheral wall of the stationary blade member 4 and the inner peripheral wall of the air guiding ring 11, thereby preventing the stationary blade member 4 from rotating. Of course, the present invention is not limited thereto, and the fixing member 5 may also be a snap structure formed on the inner peripheral wall of the air guiding ring 11. When the stationary blade member 4 is in the first position, the snap can be engaged with the stationary blade member 4 to limit the rotation of the stationary blade member 4.

[0068] In some embodiments of the present invention, as Figure 2 、 Figure 4 and Figure 5 shown, the driving mechanism 6 includes a driving component 61 and a reset component 62. Specifically, the driving component 61 includes a first driving member 611 and a second driving member 612. The first driving member 611 is provided on the fixed bracket 1, and the second driving member 612 is provided on the stationary blade member 4. When the driving component 61 is powered on, there is a repulsive force between the first driving member 611 and the second driving member 612 to drive the stationary blade member 4 to move from the first position to the second position.

[0069] Optionally, at least one of the first driving member 611 and the second driving member 612 is an energized coil. Specifically, one of the first driving member 611 and the second driving member 612 is an energized coil, and the other of the first driving member 611 and the second driving member 612 is a permanent magnet. When the energized coil is powered on, it can make the opposite surfaces of the energized coil and the permanent magnet have the same magnetism, so that there is a repulsive force between the first driving member 611 and the second driving member 612. Preferably, the first driving member 611 is an energized coil and the second driving member 612 is a permanent magnet, thereby improving the technical problem that the signal line connected to the energized coil is wound when the stationary blade member 4 rotates in the second position.

[0070] Optionally, both the first driving member 611 and the second driving member 612 are energized coils. When both the first driving member 611 and the second driving member 612 are powered on, there can be a repulsive force between the first driving member 611 and the second driving member 612, so that the stationary blade member 4 moves from the first position to the second position.

[0071] As Figure 3 、 Figure 4 and Figure 8As shown, one end of the reset component 62 is connected to the fixed bracket 1, and the other end of the reset component 62 is connected to the stationary blade member 4 to constantly drive the stationary blade member 4 to move from the second position to the first position. Thus, after the drive component 61 is powered off, the stationary blade member 4 can move from the second position to the first position under the action of the reset component 62. It can be understood that when the stationary blade member 4 moves from the first position to the second position, the drive component 61 can be powered on. There is a repulsive force between the first drive member 611 and the second drive member 612, and the repulsive force between the first drive member 611 and the second drive component 61 is greater than the acting force exerted on the stationary blade member 4 by the reset component 62, so that the stationary blade member 4 can move from the first position to the second position.

[0072] Furthermore, the reset component 62 includes a first reset member and a second reset member. The first reset member is arranged on the fixed bracket 1, and the second reset member is arranged on the stationary blade 43. There is an attractive force between the first reset member and the second reset member. Thus, after the drive component 61 is powered off, under the action of the attractive force between the first reset member and the second reset member, the stationary blade member 4 can move from the second position to the first position.

[0073] Optionally, one of the first reset member and the second reset member is a permanent magnet, and the other of the first reset member and the second reset member is a metal member. Of course, the present invention is not limited thereto. One of the first reset member and the second reset member can be an energized coil, and the other of the first reset member and the second reset member can be a metal member. Preferably, the first reset member is an energized coil and the second reset member is a metal member, thereby improving the technical problem that the signal wire of the energized coil on the stationary blade member 4 is wound during the rotation of the stationary blade member 4.

[0074] Of course, the present invention is not limited thereto. One of the first reset member and the second reset member is an energized coil, and the other of the first reset member and the second reset member is a permanent magnet. When the energized coil is energized, there can be an attractive force between the first reset member and the second reset member.

[0075] In addition, the drive component 61 and the reset component 62 can be interchanged, that is, the drive component 61 can drive the stationary blade member 4 to move from the second position to the first position, and the reset component 62 can drive the stationary blade member 4 to move from the first position to the second position. Since its drive principle is the same as the above principle, it will not be elaborated here.

[0076] In some other examples of the present invention, the reset component 62 includes an elastic member 621. One end of the elastic member 621 is connected to the fixed bracket 1, and the other end of the elastic member 621 is connected to the stator blade member 4. Under the action of the elastic force of the elastic member 621, the stator blade member 4 can be continuously driven to move from the second position to the first position. For example, one end of the elastic member 621 can be directly connected to the fixed bracket 1 through a fastener, and the other end of the elastic member 621 is connected to the stator blade member 4 through a fastener. When the driving mechanism 6 is located between the stator blade member 4 and the wind wheel 3, the driving component 61 is energized, and the stator blade member 4 moves to the second position, and the elastic member 621 elongates. When the driving component 61 is de-energized, the stator blade member 4 moves to the first position under the action of the resilience of the elastic member 621.

[0077] Further, the reset component 62 further includes a positioning member 622. One end of the positioning member 622 is connected to the other end of the elastic member 621, and the other end of the positioning member 622 is connected to the stator blade member 4. The elastic member 621 and the positioning member 622 can be arranged along the moving direction of the stator blade member 4. The setting of the positioning member 622 can reduce the length of the elastic member 621.

[0078] Of course, the present invention is not limited thereto. As Figure 3 、 Figure 4 and Figure 5 shown, the positioning member 622 includes a stop portion 6221 and a connecting portion 6222. One end of the connecting portion 6222 is connected to the stop portion 6221. The diameter of the stop portion 6221 is larger than that of the connecting portion 6222. The elastic member 621 is sleeved on the connecting portion 6222 and the other end of the elastic member 621 abuts against the stop portion 6221. The other end of the connecting portion 6222 is connected to the stator blade 43. For example, in Figure 3 、 Figure 4 and Figure 5 shown in the example, the connecting portion 6222 passes through the motor cover 122. The stop portion 6221 is located on the side of the motor cover 122 away from the stator blade member 4. The elastic member 621 is sleeved on the connecting portion 6222 and is located between the stop portion 6221 and the motor cover 122. The other end of the connecting portion 6222 is connected to the stator blade member 4. When the driving component 61 is energized, there is a repulsive force between the first driving member 611 and the second driving member 612, and the stator blade member 4 moves from the first position to the second position, and the elastic member 621 is compressed. When the driving component 61 is de-energized, the repulsive force between the first driving member 611 and the second driving member 612 disappears, and under the action of the resilience of the elastic member 621, the stator blade member 4 moves from the second position to the first position.

[0079] Further, as Figure 9 and Figure 10As shown, the connecting portion 6222 is provided with a wire passing hole 6223 extending in the axial direction, and a wire routing hole 6224 communicating with the wire passing hole 6223 is provided on the outer peripheral wall of the connecting portion 6222. Thus, the signal wires of the driving assembly 61 can pass through the wire passing hole 6223 and the wire routing hole 6224, thereby improving the problem of the signal wires being wound when the stationary blade member 4 rotates.

[0080] For example, in Figure 9 and Figure 10 In the example shown, the connecting portion 6222 is provided with a wire passing hole 6223 extending in the axial direction, and two wire routing holes 6224 communicating with the wire passing hole 6223 are provided on the outer peripheral wall of the connecting portion 6222, and the two wire routing holes 6224 are spaced apart along the axial direction of the connecting portion 6222. The signal wires include a main wire a and a branch wire b. The main wire can extend into the wire passing hole 6223 from one of the wire routing holes 6224, and the main wire extends out from one axial end of the wire passing hole 6223 of the connecting portion 6222 and is electrically connected to the energized coil on the stationary blade member 4. The branch wire is connected to the main wire, and the branch wire passes out from the other wire routing hole 6224 and is electrically connected to the energized coil on the fixed bracket 1. Thus, when the stationary blade member 4 rotates, the problem of the signal wires connected to the energized coil on the stationary blade member 4 being wound can be improved.

[0081] Optionally, the reset assembly 62 may further include a support member 623. The support member 623 is provided between the elastic member 621 and the fixed bracket 1. One end of the elastic member 621 can abut against the support member 623, thereby increasing the friction force between the fixed bracket 1 and the elastic member 621, avoiding the elastic member 621 rotating together during the rotation of the stationary blade member 4, and improving the problem of the signal wires being wound.

[0082] For example, in Figure 3 、 Figure 4 and Figure 5In the illustrated example, the positioning member 622 includes a stop portion 6221 and a connecting portion 6222. One end of the connecting portion 6222 is connected to the stop portion 6221. The diameter of the stop portion 6221 is greater than that of the connecting portion 6222. The connecting portion 6222 is passed through the support member 623 and the motor cover 122. The stop portion 6221 is located on the side of the motor cover 122 away from the stationary blade member 4. The support member 623 is provided on the side of the motor cover 122 away from the stationary blade member 4. The support member 623 is provided with a through hole. The elastic member 621 is sleeved on the connecting portion 6222 and is located between the stop portion 6221 and the support member 623. The other end of the connecting portion 6222 is connected to the stationary blade member 4. When the driving assembly 61 is powered on, there is a repulsive force between the first driving member 611 and the second driving member 612, and the stationary blade member 4 moves from the first position to the second position, and the elastic member 621 is compressed. When the driving assembly 61 is powered off, the repulsive force between the first driving member 611 and the second driving member 612 disappears, and under the action of the resilience of the elastic member 621, the stationary blade member 4 moves from the second position to the first position.

[0083] In some embodiments of the present invention, as Figure 1 and Figure 5 shown, the stationary blade member 4 includes an annular first fixing portion 41, a second fixing portion 42, and a plurality of stationary blades 43. The second fixing portion 42 is provided inside the first fixing portion 41 and is spaced apart from the first fixing portion 41. The second fixing portion 42 can be in a disc shape. The driving mechanism 6 is connected to the second fixing portion 42. The plurality of stationary blades 43 are provided between the first fixing portion 41 and the second fixing portion 42, and the plurality of stationary blades 43 are circumferentially spaced along the second fixing portion 42. Thus, the structure of the stationary blade member 4 is simple and convenient for processing and manufacturing.

[0084] The air conditioner 1000 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0085] As Figure 1 and Figure 2 shown, the air conditioner 1000 according to an embodiment of the present invention includes a housing 200, a heat exchanger 300, and the above-mentioned fan assembly 100.

[0086] Specifically, an air inlet 201 and an air outlet 202 are formed on the housing 200. An air inlet grille may be provided at the air inlet 201, and the air inlet grille has the function of filtering air. The heat exchanger 300 is provided inside the housing 200. The fan assembly 100 is disposed corresponding to the air outlet 202, and the fan assembly 100 drives air flow to blow out from the air outlet 202.

[0087] Optionally, the air conditioner 1000 may be a split wall-mounted air conditioner 1000, and the air conditioner 1000 may also be a split floor-standing air conditioner 1000.

[0088] When the air conditioner 1000 is operating, the driving motor 2 drives the wind wheel 3 to rotate. External air enters the casing 200 from the air inlet 201, exchanges heat through the heat exchanger 300, and then flows through the wind wheel 3 and the stationary vane member 4 and exits from the air outlet 202, thereby adjusting the indoor environmental temperature. When the stationary vane member 4 is in the first position, the stationary vane member 4 does not rotate, and the moving air flow generated when the wind rotates can directly blow out through the gaps of the stationary vane member 4. When the stationary vane member 4 is in the second position, the moving air flow generated when the wind rotates can drive the stationary vane member 4 to rotate when flowing through the stationary vane member 4. By disturbing the air flow through the rotation of the stationary vane member 4, the air flow vorticity can be increased, and a swirling wind feeling can be obtained, making the air flow discharged from the air outlet 202 closer to natural wind and enhancing the user experience. In addition, different wind feelings and air supply modes can be realized by switching the stationary vane member 4 between the first position and the second position.

[0089] Optionally, the air conditioner 1000 may further include an electric auxiliary heater 400. The electric auxiliary heater 400 is located between the heat exchanger 300 and the fan assembly 100, and can further increase the air outlet temperature through the electric auxiliary heater 400 in the heating mode of the air conditioner 1000, thereby improving the heating performance of the air conditioner 1000.

[0090] According to the air conditioner 1000 of the embodiment of the present invention, by providing the above-mentioned fan assembly 100, various wind feelings and air supply forms can be provided, and the user experience can be enhanced.

[0091] In some embodiments of the present invention, as Figure 2 shown, the stationary vane member 4 of the fan assembly 100 is located outside the corresponding air outlet 202 and outside the casing 200, whereby the flow path of the air flow can be extended, and the air flow direction can be better adjusted.

[0092] In some embodiments of the present invention, the air outlets 202 are multiple and arranged at intervals, and the fan assemblies 100 are multiple groups, and the fan assemblies 100 are arranged in one-to-one correspondence with the air outlets 202. Thus, by providing the multiple air outlets 202, the air output can be increased, and by arranging the fan assembly 100 at each air outlet 202, the air output at each air outlet 202 can have a swirling wind feeling, further enhancing the user experience. Optionally, each fan assembly 100 can be independently controlled.

[0093] For example, in Figure 1 and Figure 2In the example, the air conditioner 1000 is a split wall-mounted air conditioner 1000. The air conditioner 1000 includes an indoor unit and an outdoor unit. The indoor unit includes the above-mentioned housing 200, heat exchanger 300, fan assembly 100, and electric auxiliary heating 400. An air inlet 201 is formed at the top of the housing 200, and an air outlet 202 is formed at the lower front side of the housing 200. Three air outlets 202 are formed on the housing 200, and the three air outlets 202 are arranged in the left-right direction. Correspondingly, there are three groups of fan assemblies 100, and the three groups of fan assemblies 100 are respectively arranged in one-to-one correspondence with the three air outlets 202. Among them, the central axis of each fan assembly 100 extends obliquely downward in the front-to-back direction.

[0094] Thus, when the air conditioner 1000 is operating, each fan assembly 100 can generate a swirling air feeling, which is blown out through the corresponding air outlet 202 into the room, enabling the user to feel an air feeling close to natural wind and improving the user experience.

[0095] In some embodiments of the present invention, as Figure 6 and Figure 7 shown, the fixing bracket 1 is provided with fixing parts 111. The fixing parts 111 are multiple and spaced apart. Each fixing part 111 is provided with a screw hole. The fixing bracket 1 can be connected to the housing 200 by screws. In addition, the fixing bracket 1 is further provided with a limiting part 112 spaced apart from the fixing parts 111. The housing 200 can be provided with a limiting groove corresponding to the limiting part 112. During the installation process of the fan assembly 100, the limiting part 112 and the limiting groove can be first engaged, and then the fixing parts 111 can be connected to the housing 200, which is convenient for the installation of the fan assembly 100.

[0096] For example, in the example shown in Figure 6 and Figure 7 the fixing bracket 1 includes a wind guiding ring 11. A plurality of spaced-apart fixing parts 111 are provided on the outer peripheral wall of the wind guiding ring 11. Each fixing part 111 is provided with a screw hole. A limiting part 112 is also provided on the outer peripheral wall of the wind guiding ring 11. The housing 200 is provided with a limiting groove that cooperates with the limiting part 112.
