[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] Hereinafter, an air conditioner according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0039] Reference Figure 1-Figure 10 The air conditioner according to the embodiment of the present invention includes a casing 10 , a first air guide plate 20 , a second air guide plate 21 , a driving mechanism 30 , and a heat exchange and air supply assembly 15 .

[0040] The housing 10 has an air inlet 11 and an air outlet 12. The heat exchange air supply assembly 15 is arranged in the housing 10, and the heat exchange air supply assembly 15 is located between the air inlet 11 and the air outlet 12. The heat exchange air supply assembly 15 may include a heat exchanger component 151 and a fan component 152. The heat exchanger component 151 may be arranged adjacent to the air inlet 11, and the fan component 152 may be located on a side of the heat exchanger component 151 adjacent to the air outlet 12. When the air conditioner is working, the fan component 152 drives the indoor air to enter the housing 10 from the air inlet 11, and after heat exchange with the heat exchanger component 151, it is discharged into the room through the air outlet 12, thereby adjusting the indoor temperature.

[0041] The first air guide plate 20 and the second air guide plate 21 are both rotatably disposed at the air outlet 12. By rotating the first air guide plate 20 and the second air guide plate 21, the air outlet direction of the air outlet 12 can be adjusted, and the air outlet effect can also be adjusted; the air outlet 12 can also be opened or closed by rotating the first air guide plate 20 and the second air guide plate 21.

[0042] The driving mechanism 30 is used to drive the first air guide plate 20 and the second air guide plate 21 to rotate simultaneously. The driving mechanism 30 includes a motor and a transmission mechanism 31. The transmission mechanism 31 can driveably connect the first air guide plate 20 and the motor, and the transmission mechanism 31 can also driveably connect the second air guide plate 21 and the motor. When the driving mechanism 30 is working, the driving mechanism 30 transmits power to the first air guide plate 20 and the second air guide plate 21 through the transmission mechanism 31, thereby driving the first air guide plate 20 and the second air guide plate 21 to rotate simultaneously. When the driving mechanism 30 stops working, the first air guide plate 20 and the second air guide plate 21 both stop moving. Since the first air guide plate 20 and the second air guide plate 21 can be driven to rotate simultaneously by one motor, the number of motors used to drive the air guide plates to rotate can be reduced, the structure can be simplified, and the cost can be reduced.

[0043] When the first air guide plate 20 and the second air guide plate 21 rotate simultaneously, the angular velocity of the first air guide plate 20 is different from the angular velocity of the second air guide plate 21. Since the angular velocities of the first air guide plate 20 and the second air guide plate 21 are different, the driving mechanism 30 drives the first air guide plate 20 and the second air guide plate 21 to rotate at different angles and strokes, so that the first air guide plate 20 and the second air guide plate 21 can cooperate at different positions, thereby achieving different air supply effects of the air conditioner.

[0044] According to the air conditioner of the embodiment of the present invention, by providing the driving mechanism 30, it is possible to achieve that one motor drives the first air guide plate 20 and the second air guide plate 21 to move simultaneously, which can reduce the number of driving motors for the air guide plates in the air conditioner, thereby reducing the production cost. The first air guide plate 20 and the second air guide plate 21 rotate simultaneously, and the angular velocities are different, so that the first air guide plate 20 and the second air guide plate 21 rotate at different angles and travels during the movement, thereby achieving different air supply effects of the air conditioner.

[0045] Reference Figure 11-13 According to some embodiments of the present invention, the first air guide plate 20 and the second air guide plate 21 are adapted to move along the same circle. With this arrangement, the first air guide plate 20 and the second air guide plate 21 can be more reasonably matched, so that the air guiding effect of the first air guide plate 20 and the second air guide plate 21 can be better achieved. In addition, the first air guide plate 20 and the second air guide plate 21 can move 360° along the above-mentioned circle to achieve air guiding swirl, further diversifying the air outlet effect of the air conditioner and meeting more air outlet requirements.

[0046] Reference Figure 1-Figure 5 and Fig.11 According to some embodiments of the present invention, the air conditioner has a closed state, in which the first air guide plate 20 and the second air guide plate 21 jointly close the air outlet 12. When the air conditioner is in the closed state, the first air guide plate 20 and the second air guide plate 21 are both located at the air outlet 12 and jointly close the air outlet 12. This arrangement can prevent external dust from entering the air conditioner through the air outlet 12 when the air conditioner is in the closed state. In addition, the first air guide plate 20 and the second air guide plate 21 move along the same circle, which can ensure the closing effect of the first air guide plate 20 and the second air guide plate 21.

[0047] Reference Figure 6-Figure 10 and Figure 12-13 According to some embodiments of the present invention, the air conditioner has a cooling state and a heating state.

[0048] In the cooling state, the first air guide plate 20 and the second air guide plate 21 jointly define a first air guide channel 22, and the air outlet end of the first air guide channel 22 faces directly forward or directly above. The first air guide channel 22 jointly defined by the first air guide plate 20 and the second air guide plate 21 can extend the air duct and increase the air volume. In addition, the air outlet end of the first air guide channel 22 faces directly forward or directly above, which can guide the airflow, so that the airflow diverges directly forward or directly above after flowing out of the air outlet 12, and can prevent direct blowing while realizing the cooling function, thereby improving the airflow comfort, and making the cooling airflow flow downward from the upper space of the room, thereby improving the indoor temperature uniformity, thereby improving comfort.

[0049] In the heating state, the first air guide plate 20 and the second air guide plate 21 jointly define a second air guide channel 23, and the air outlet end of the second air guide channel 23 faces the front and bottom. The second air guide channel 23 jointly defined by the first air guide plate 20 and the second air guide plate 21 can extend the air duct and increase the air volume. In addition, the air outlet end of the second air guide channel 23 faces the front and bottom, which can guide the airflow, so that the airflow diverges toward the front and bottom after flowing out of the air outlet 12, and the heating airflow flows upward from the lower space of the room, thereby improving the uniformity of the indoor temperature and thus improving the comfort.

[0050] Reference Figure 1-Figure 13 According to some embodiments of the present invention, the size of the first air guide plate 20 in the circumferential direction of the circle is larger than the size of the second air guide plate 21 in the circumferential direction of the circle, the air outlet 12 extends in the left-right direction, and the central axis of the circle extends in the left-right direction. The size of the first air guide plate 20 in the circumferential direction of the circle is larger than the size of the second air guide plate 21 in the circumferential direction of the circle. This arrangement can better achieve the guiding effect of the first air guide plate 20 and the second air guide plate 21 on the airflow, thereby achieving a variety of air supply effects.

[0051] Reference Fig.12 In the cooling state, the first air guide plate 20 is located below the second air guide plate 21, and the size of the first air guide plate 20 in the circumferential direction is larger than the size of the second air guide plate 21 in the circumferential direction. After the airflow flows through the first air guide channel 22, it changes its flow direction along the inner walls of the first air guide plate 20 and the second air guide plate 21, and flows out from the air outlet 12 along the preset direction toward the front or the front top, which can prevent direct blowing while realizing the cooling function, thereby improving the airflow comfort. Since the first air guide plate 20 is located below the second air guide plate 21 and the size of the first air guide plate 20 is larger than the size of the second air guide plate 21, it can better ensure that the cooling airflow flows out toward the front or the front top.

[0052] Reference Fig.13 In the heating state, the first air guide plate 20 is located above the second air guide plate 21. The size of the first air guide plate 20 in the circumferential direction of the circle is larger than the size of the second air guide plate 21 in the circumferential direction of the circle. After the airflow flows through the second air guide channel 23, it changes its flow direction along the inner walls of the first air guide plate 20 and the second air guide plate 21, and flows out from the air outlet 12 in a preset direction toward the front and bottom, thereby improving the airflow comfort. Since the first air guide plate 20 is located above the second air guide plate 21 and the size of the first air guide plate 20 is larger than the size of the second air guide plate 21, it can better ensure that the heating airflow flows out toward the front and bottom.

[0053] Reference Figure 11-13According to some embodiments of the present invention, the first air guide plate 20 and the second air guide plate 21 are adapted to move in the same direction. This arrangement can avoid interference between the first air guide plate 20 and the second air guide plate 21 due to different directions during movement.

[0054] The first air guide plate 20 and the second air guide plate 21 are suitable for moving in the same direction, which means that the first air guide plate 20 and the second air guide plate 21 move in the clockwise direction along the trajectory of the same circle, or the first air guide plate 20 and the second air guide plate 21 move in the counterclockwise direction along the trajectory of the same circle.

[0055] Reference Figure 11-13 According to some embodiments of the present invention, when the first air guide plate 20 and the second air guide plate 21 rotate simultaneously, the angular velocity of the first air guide plate 20 is smaller than the angular velocity of the second air guide plate 21. When the first air guide plate 20 and the second air guide plate 21 jointly close the air outlet 12, along the circumferential direction of the circle, the second air guide plate 21 is located on one side of the movement direction of the first air guide plate 20. When the first air guide plate 20 and the second air guide plate 21 rotate simultaneously within the same circle, the angular velocity of the first air guide plate 20 is smaller than the angular velocity of the second air guide plate 21. Therefore, within the same time, the rotation angle of the first air guide plate 20 is smaller than the rotation angle of the second air guide plate 21, so that the first air guide plate 20 and the second air guide plate 21 can be coordinated at different positions, and various air supply effects can be achieved. When the first air guide plate 20 and the second air guide plate 21 jointly close the air outlet 12, the second air guide plate 21 is located on one side of the movement direction of the first air guide plate 20. Through this arrangement, when the first air guide plate 20 and the second air guide plate 21 start to move from the position of closing the air outlet 12, interference between the first air guide plate 20 and the second air guide plate 21 can be avoided, and the closing effect of the first air guide plate 20 and the second air guide plate 21 can be ensured, thereby preventing external dust from entering the air conditioner through the air outlet 12 when the air conditioner is in a closed state.

[0056] Among them, along the circumferential direction of the circle, the second air guide plate 21 is located on one side of the movement direction of the first air guide plate 20, which can be understood as: when the movement directions of the first air guide plate 20 and the second air guide plate 21 are both along the clockwise direction of the above-mentioned circle, the second air guide plate 21 is located on one side of the first air guide plate 20 in the clockwise direction; when the movement directions of the first air guide plate 20 and the second air guide plate 21 are both along the counterclockwise direction of the above-mentioned circle, the second air guide plate 21 is located on one side of the first air guide plate 20 in the counterclockwise direction.

[0057] Reference Figure 1-Figure 10According to some embodiments of the present invention, the housing 10 has an air outlet passage 13 located at the downstream side of the heat exchange air supply assembly 15. At least a portion of the inner wall of the air outlet passage 13 is recessed and formed with a avoidance surface 14. The avoidance surface 14 is formed as an arc surface, and the arc surface is adapted to the outer peripheral surface of the first air guide plate 20 and the second air guide plate 21. During the process of the first air guide plate 20 and the second air guide plate 21 moving along the above-mentioned circle, the avoidance surface 14 formed on the inner wall of the air outlet passage 13 can be used to avoid the first air guide plate 20 and the second air guide plate 21. By providing the avoidance surface 14 on the inner wall of the air outlet passage 13, it is possible to avoid the first air guide plate 20 and the second air guide plate 21 from interfering with the inner wall of the air outlet passage 13 during the movement process, thereby ensuring the smoothness of the movement of the first air guide plate 20 and the second air guide plate 21, and also making the overall structure compact.

[0058] Reference Figure 1-Figure 10 According to some embodiments of the present invention, the transmission mechanism 31 includes a first transmission member 32, a second transmission member 33 and a third transmission member 34, the first transmission member 32 is connected to the motor shaft of the motor, the second transmission member 33 and the third transmission member 34 are both engaged with the first transmission member 32, the first air guide plate 20 is connected to the second transmission member 33, for example, the first air guide plate 20 is fixedly connected to the axis of the second transmission member 33, the second air guide plate 21 is connected to the third transmission member 34, for example, the second air guide plate 21 is fixedly connected to the axis of the third transmission member 34, the transmission ratio of the second transmission member 33 to the first transmission member 32 is a first transmission ratio, the transmission ratio of the third transmission member 34 to the first transmission member 32 is a second transmission ratio, and the second transmission ratio is different from the first transmission ratio.

[0059] The motor drives the first transmission member 32 connected to the motor shaft of the motor to rotate, the first transmission member 32 drives the second transmission member 33 and the third transmission member 34 engaged with the first transmission member 32 to rotate, the second transmission member 33 drives the first air guide plate 20 connected thereto to rotate, and the third transmission member 34 drives the second air guide plate 21 connected thereto to rotate, thereby realizing the function of one motor driving the first air guide plate 20 and the second air guide plate 21 to rotate at the same time, which can reduce the setting of the motor, simplify the structure and reduce the production cost.

[0060] The transmission ratio of the second transmission member 33 to the first transmission member 32 is the first transmission ratio, and the transmission ratio of the third transmission member 34 to the first transmission member 32 is the second transmission ratio, and the second transmission ratio is different from the first transmission ratio. By setting different transmission ratios, when the first transmission member 32 drives the second transmission member 33 and the third transmission member 34 to rotate at the same time, the second transmission member 33 and the third transmission member 34 can have different angular velocities, so that the first air guide plate 20 and the second air guide plate 21 rotate at different angles and strokes in the same time. This structural setting can easily realize that the same motor drives the first air guide plate 20 and the second air guide plate 21 to rotate and the angular velocities of the first air guide plate 20 and the second air guide plate 21 are different.

[0061] Reference Figure 1-Figure 10 According to some embodiments of the present invention, the driving mechanism 30 further includes an inner gear ring 35, the inner gear ring 35 surrounds the outer circumference of the first transmission member 32, and the inner circumferential wall of the inner gear ring 35 is spaced apart from the outer circumferential wall of the first transmission member 32, the second transmission member 33 and the third transmission member 34 are both located between the inner gear ring 35 and the first transmission member 32, and the second transmission member 33 and the third transmission member 34 are both meshed with the inner gear ring 35 and the first transmission member 32. By providing the inner gear ring 35, the inner gear ring 35 surrounds the outer circumference of the first transmission member 32 and is spaced apart from the first transmission member 32, so that the first transmission member 32 can avoid interference with the inner gear ring 35 during rotation. The second transmission member 33 and the third transmission member 34 are both located between the inner gear ring 35 and the first transmission member 32 and mesh with the inner gear ring 35 and the first transmission member 32. This arrangement can limit the movement trajectory of the second transmission member 33 and the third transmission member 34, and has a guiding effect on the second transmission member 33 and the third transmission member 34, so that the second transmission member 33 and the third transmission member 34 are both in the inner gear ring 35 and move along the axial direction of the inner gear ring 35, so as to conveniently realize that the first air guide plate 20 and the second air guide plate 21 are driven by the same motor to rotate and move along the same circumference. The above-mentioned circumference can be a circumference arranged concentrically with the inner gear ring 35 and located between the inner gear ring 35 and the first transmission member 32.

[0062] Optionally, the inner gear ring 35 may be arranged concentrically with the first transmission member 32 and the motor shaft.

[0063] Reference Figure 1-Figure 10 According to some embodiments of the present invention, the first transmission member 32 includes a first gear 322 shaft 321, a first gear 322 and a second gear 323. The first gear 322 and the second gear 323 are both installed on the first gear 322 shaft 321 and are arranged at intervals along the axial direction of the first gear 322 shaft 321. The first gear 322 is meshed with the second transmission member 33, and the second gear 323 is meshed with the third transmission member 34.

[0064] Among them, the second transmission member 33 may include a second gear 323 shaft and a third gear installed on the second gear 323 shaft, the first gear 322 is suitable for meshing with the third gear, and the first air guide plate 20 can be fixedly connected to the second gear 323 shaft through a first connecting bracket; the third transmission member 34 may include a third gear shaft and a fourth gear installed on the third gear shaft, the second gear 323 is suitable for meshing with the fourth gear, and the second air guide plate 21 can be fixedly connected to the third gear shaft through a second connecting bracket.

[0065] Through this arrangement, the first gear 322 is meshed with the second transmission member 33, the second transmission member 33 is connected to the first air guide plate 20, the second gear 323 is meshed with the third transmission member 34, and the third transmission member 34 is connected to the second air guide plate 21. During the rotation process, the motor drives the first gear 322 shaft 321 connected to the motor shaft of the motor, the first gear 322 and the second gear 323 to rotate, the first gear 322 drives the second transmission member 33 to rotate, the second transmission member 33 drives the first air guide plate 20 to rotate, and at the same time, the second gear 323 drives the third transmission member 34 to rotate, and the third transmission member 34 drives the second air guide plate 21 to rotate, thereby realizing the function of one motor driving the first air guide plate 20 and the second air guide plate 21 to rotate simultaneously, with a simple structure and low cost.

[0066] The first gear 322 and the second gear 323 are both installed on the first gear 322 shaft 321 and are arranged at intervals along the axial direction of the first gear 322 shaft 321. Therefore, the angular velocity of rotation of the first gear 322 and the second gear 323 is the same, the pitch circle diameters of the first gear 322 and the second gear 323 are different, and the pitch circle diameters of the second transmission member 33 and the third transmission member 34 are different, so that the first transmission ratio is different from the second transmission ratio, thereby making the angular velocity of the second transmission member 33 and the third transmission member 34 different.

[0067] For example, refer to Figure 3 The pitch circle diameter of the first gear 322 is d1 (refer to Figure 3 The pitch circle diameter of the second gear 323 is d2 (refer to Figure 3 The pitch circle diameter of the second transmission member 33 is d3 (refer to Figure 3 The pitch circle diameter of the third transmission member 34 is d4 (refer to Figure 3 The transmission ratio of the gear transmission mechanism 31 is equal to the pitch circle diameter of the driven wheel / the pitch circle diameter of the driving wheel. The first transmission ratio of the second transmission member 33 to the first transmission member 32 is d3 / d1, and the second transmission ratio of the third transmission member 34 to the first transmission member 32 is d4 / d2. Since d3>d4 and d1<d2, d3 / d1>d4 / d2, that is, the first transmission ratio is greater than the second transmission ratio.

[0068] The speed of the driven wheel is equal to the speed of the driving wheel / the transmission ratio of the gear transmission mechanism 31, the speed of the motor is ω, the speed of the second transmission member 33 is (ω*d1) / d3, and the speed of the first air guide plate 20 connected to the second transmission member 33 is (ω*d1) / d3; the speed of the third transmission member 34 is (ω*d2) / d4, and the speed of the second air guide plate 21 connected to the third transmission member 34 is (ω*d2) / d4. Because d3>d4 and d1<d2, therefore (ω*d1) / d3<(ω*d2) / d4, that is, the speed of the second transmission member 33 is less than the speed of the third transmission member 34, the speed of the first air guide plate 20 is less than the speed of the second air guide plate 21, that is, the angular velocity of the first air guide plate 20 is less than the angular velocity of the second air guide plate 21, so that within the corresponding time, the rotation angle of the first air guide plate 20 is less than the rotation angle of the second air guide plate 21.

[0069] Furthermore, the sizes of the pitch circle diameters of the first gear 322, the second gear 323, the second transmission member 33 and the third transmission member 34 can be controlled according to the size of the inner gear ring 35 to control the size of the first transmission ratio and the second transmission ratio, thereby preventing the rotation speed of the second air guide plate 21 from being too fast compared to the rotation speed of the first air guide plate 20, causing interference between the first air guide plate 20 and the second air guide plate 21 during movement.

[0070] Reference Figure 1-Figure 13 According to some embodiments of the present invention, the first air guide plate 20 and the second air guide plate 21 are both located on the outer circumference of the inner gear ring 35, and the first air guide plate 20 and the second air guide plate 21 are both suitable for circumferential movement along the inner gear ring 35. By arranging the first air guide plate 20 and the second air guide plate 21 on the outer circumference of the inner gear ring 35, it is possible to avoid interference between the first air guide plate 20 and the second air guide plate 21 and the inner gear ring 35 during movement, thereby ensuring the smoothness of the rotation of the first air guide plate 20 and the second air guide plate 21; and the outer circumferential surface of the inner gear ring 35 can also guide the circumferential movement of the first air guide plate 20 and the second air guide plate 21 along the inner gear ring 35, and also make the overall structure compact.

[0071] Reference body 1 below Fig.13 An air conditioner according to some embodiments of the present invention is described.

[0072] Reference Figure 1-Figure 13 In this embodiment, the air conditioner can be a split wall-mounted air conditioner, and the air conditioner can include an outdoor air conditioner and an indoor air conditioner 100. The indoor air conditioner 100 includes a housing 10, a first air guide plate 20, a second air guide plate 21, a driving mechanism 30, and a heat exchange and air supply assembly 15, and the heat exchange and air supply assembly 15 includes a heat exchanger component 151 and a fan component 152.

[0073] The housing 10 has an air inlet 11, an air outlet 12 and an air outlet channel 13. The air inlet 11 can be formed at the top and back of the housing 10, and the air outlet 12 can be formed at the front lower part of the housing 10. The first air guide plate 20 and the second air guide plate 21 are both arranged at the air outlet 12. The driving mechanism 30 includes a motor and a transmission mechanism 31. The transmission mechanism 31 can drive the first air guide plate 20 to be connected to the motor and the second air guide plate 21 to be connected to the motor. The driving mechanism 30 is used to drive the first air guide plate 20 and the second air guide plate 21 to rotate simultaneously. When the first air guide plate 20 and the second air guide plate 21 rotate simultaneously, the angular velocity of the first air guide plate 20 is different from the angular velocity of the second air guide plate 21. The heat exchange air supply assembly 15 is located inside the housing 10.

[0074] After the air enters the casing 10 through the air inlet 11, it is processed by the heat exchange and air supply assembly 15 and flows out from the air outlet 12, thereby realizing the air conditioning function of the air conditioner. By setting the first air guide plate 20 and the second air guide plate 21, the first air guide plate 20 and the second air guide plate 21 can change the direction of air outflow by cooperating at different positions. While realizing the cooling and heating functions, it can achieve a variety of air supply effects and improve the comfort of air supply.

[0075] The first air guide plate 20 and the second air guide plate 21 are suitable for moving along the same circle. The air conditioner has a closed state. In the closed state, the first air guide plate 20 and the second air guide plate 21 jointly close the air outlet 12. The air conditioner also has a cooling state and a heating state.

[0076] In the cooling state, the first air guide plate 20 and the second air guide plate 21 jointly define a first air guide channel 22, and the air outlet end of the first air guide channel 22 faces straight ahead or front upward, so that the airflow diverges toward the straight ahead or front upward after flowing out from the air outlet 12, which can prevent direct blowing while realizing the cooling function, thereby improving the airflow comfort.

[0077] In the heating state, the first air guide plate 20 and the second air guide plate 21 jointly define a second air guide channel 23, and the air outlet end of the second air guide channel 23 faces the front and bottom, so that the airflow diverges toward the front and bottom after flowing out from the air outlet 12, thereby improving the heating effect and the heating efficiency to a certain extent.

[0078] The size of the first air guide plate 20 in the circumferential direction of the circle is greater than that of the second air guide plate 21 in the circumferential direction of the circle. The air outlet 12 extends in the left-right direction, and the central axis of the circle extends in the left-right direction.

[0079] In the cooling state, the first air guide plate 20 is located below the second air guide plate 21. After the air flow passes through the first air guide channel 22, it changes direction along the inner walls of the first air guide plate 20 and the second air guide plate 21, and flows out from the air outlet 12 along a preset direction toward the front or the upper front.

[0080] In the heating state, the first air guide plate 20 is located above the second air guide plate 21. After the air flow passes through the second air guide channel 23, it changes direction along the inner walls of the first air guide plate 20 and the second air guide plate 21, and flows out from the air outlet 12 toward the front and bottom along a preset direction.

[0081] The first air guide plate 20 and the second air guide plate 21 are suitable for moving in the same direction, that is, the first air guide plate 20 and the second air guide plate 21 move in the clockwise direction within the same circle, or the first air guide plate 20 and the second air guide plate 21 move in the counterclockwise direction within the same circle.

[0082] The casing 10 has an air outlet channel 13 located on the downstream side of the heat exchange and air supply assembly 15. At least a portion of the inner wall of the air outlet channel 13 is recessed and formed with a avoidance surface 14. The avoidance surface 14 is formed as an arc surface for avoiding the first air guide plate 20 and the second air guide plate 21.

[0083] The transmission mechanism 31 includes a first transmission member 32, a second transmission member 33 and a third transmission member 34. The first transmission member 32 is connected to the motor shaft of the motor, and the second transmission member 33 and the third transmission member 34 are both engaged with the first transmission member 32. The first air guide plate 20 is connected to the second transmission member 33, and the second air guide plate 21 is connected to the third transmission member 34. The transmission ratio of the second transmission member 33 to the first transmission member 32 is the first transmission ratio, and the transmission ratio of the third transmission member 34 to the first transmission member 32 is the second transmission ratio. The second transmission ratio is different from the first transmission ratio, so that the second transmission member 33 and the third transmission member 34 have different angular velocities, so that the first air guide plate 20 and the second air guide plate 21 rotate at different angles and strokes within the same time.

[0084] The driving mechanism 30 further includes an inner gear ring 35, which surrounds the outer circumference of the first transmission member 32 and is spaced apart from the first transmission member 32. The second transmission member 33 and the third transmission member 34 are both located between the inner gear ring 35 and the first transmission member 32 and are meshed with the inner gear ring 35 and the first transmission member 32, so that the second transmission member 33 and the third transmission member 34 are both inside the inner gear ring 35 and move along the circumference of the inner gear ring 35. The inner gear ring 35 and the motor are arranged at one end of the air conditioner indoor unit 100, and the inner gear ring 35 is arranged concentrically with the first transmission member 32 and the motor shaft.

[0085] The first transmission member 32 includes a first gear 322 shaft 321, a first gear 322 and a second gear 323. The first gear 322 and the second gear 323 are both mounted on the gear shaft and spaced apart along the axial direction of the gear shaft. The first gear 322 meshes with the second transmission member 33, and the second gear 323 meshes with the third transmission member 34. The first air guide plate 20 and the second air guide plate 21 are both located on the outer circumference of the inner gear ring 35 and are both adapted to move along the circumferential direction of the inner gear ring 35.

[0086] The first gear 322 is meshed with the second transmission member 33, the second transmission member 33 is connected to the first air guide plate 20, the second gear 323 is meshed with the third transmission member 34, the third transmission member 34 is connected to the second air guide plate 21. During the rotation of the motor, the first gear 322 shaft 321 connected to the motor shaft of the motor, the first gear 322 and the second gear 323 are driven to rotate, the first gear 322 drives the second transmission member 33 to rotate, the second transmission member 33 drives the first air guide plate 20 to rotate, and at the same time, the second gear 323 drives the third transmission member 34 to rotate, and the third transmission member 34 drives the second air guide plate 21 to rotate. Because the first transmission ratio is greater than the second transmission ratio, the angular velocity of the first air guide plate 20 is less than the angular velocity of the second air guide plate 21, so that within the corresponding time, the rotation angle of the first air guide plate 20 is less than the rotation angle of the second air guide plate 21.

[0087] By setting up a driving mechanism 30, the driving mechanism 30 includes a motor and a transmission mechanism 31. The motor drives the transmission mechanism 31 to rotate, and the transmission mechanism 31 drives the first air guide plate 20 and the second air guide plate 21 connected thereto to rotate, thereby realizing the function of one motor driving the first air guide plate 20 and the second air guide plate 21 to rotate simultaneously. This setting can reduce the setting of the driving motor for the air guide plate in the air conditioner, thereby reducing the production cost. At the same time, the structure is simple and can improve the space utilization rate inside the casing 10.
