[0016] As shown in Figure 1, the air conditioner 1A includes an indoor unit 10A, an outdoor unit 20A, and an expansion valve. The indoor unit 10A includes an indoor heat exchanger and an indoor fan. The outdoor unit 20A includes a compressor, an outdoor heat exchanger, and an outdoor fan. The expansion valve can be disposed in the indoor unit 10A or the outdoor unit 20A so as to expand high-pressure liquid-phase refrigerant into low-pressure gas-liquid two-phase refrigerant.

[0017] The compressor is disposed so as to compress a gaseous refrigerant in a low-temperature, low-pressure state and discharge the compressed gaseous refrigerant in a high-temperature, high-pressure state, and the high-temperature, high-pressure gaseous refrigerant flows into the condenser.

[0018] The indoor heat exchanger exchanges heat between the indoor air and the refrigerant flowing through the indoor heat exchanger to liquefy or vaporize the refrigerant. The outdoor heat exchanger is arranged to exchange heat between the outdoor air and the refrigerant flowing through the outdoor heat exchanger to liquefy or vaporize the refrigerant.

[0019] The outdoor fan is positioned to promote heat exchange between the refrigerant flowing through the heat transfer tube of the outdoor heat exchanger and the outdoor air, and the indoor fan is positioned to promote heat exchange between the refrigerant flowing through the heat transfer tube of the indoor heat exchanger and the indoor air, thereby assisting in temperature regulation.

[0020] The refrigerant circulation of the air conditioner 1 is performed by a compressor, a condenser (indoor heat exchanger or outdoor heat exchanger), an expansion valve (indoor expansion valve and outdoor expansion valve), and an evaporator (outdoor heat exchanger or indoor heat exchanger). The refrigerant circulation includes a series of processes related to compression, condensation, expansion, and evaporation, and circulates and supplies the refrigerant to the side to be regulated.

[0021] As shown in FIG. 2, in the prior art, the indoor unit 10A may be a wall-mounted indoor unit.

[0022] The indoor unit 10A includes a first housing 101A, which forms the overall appearance of the indoor unit 10A. The first housing 101A includes a top plate 1011A and a side plate 1012A, and the side plate 1012A is located on the side away from the wall surface of the first housing 101A.

[0023] The first housing 101A includes a heat exchange outlet 1013A and a heat exchange inlet 1014A, which each extend along the longitudinal direction of the indoor unit 10A. The heat exchange outlet 1013A can be installed on a side plate 1012A of the first housing 101A, and the heat exchange inlet 1014A can be installed on a top plate 1011A of the first housing 101A.

[0024] The indoor unit 10A further includes a base 102A and a heat exchange passage 103A, each of which is provided within the first housing 101A. The heat exchange passage 103A communicates with a heat exchange intake 1014A and a heat exchange outlet 1013A of the first housing 101A, and indoor air flows into the first housing 101A through the heat exchange intake 1014A, passes through the heat exchange passage 103A, and is discharged from the heat exchange outlet 1013A.

[0025] In some embodiments, the indoor heat exchanger of the indoor unit 10A is provided in the heat exchange passage 103A, for example, on the side of the heat exchange passage 103A close to the heat exchange intake port 1014A, and the indoor air passes through heat exchange in the indoor heat exchanger and is discharged from the heat exchange outlet 1013A.

[0026] In some embodiments, the indoor unit 10 further includes a drain pan. The drain pan can be installed below the indoor heat exchanger and is positioned to collect condensed water generated during the heat exchange process between the indoor air and the indoor heat exchanger. The drain pan is connected to a drain pipe extending to the outside of the first housing 101A, allowing the condensed water to be discharged to the outside of the indoor unit 10A. In some embodiments, the drain pan is integrally molded with the base 102A, thereby reducing costs and improving installation efficiency.

[0027] The indoor fan of the indoor unit 10A can be installed in the heat exchange passage. In the indoor unit 10A, the indoor air is introduced into the heat exchange passage 103A from the heat exchange inlet 1014A by the forced convection action of the indoor fan. After the indoor air is heat exchanged by the indoor heat exchanger, a heat-exchange airflow is formed, and the heat-exchange airflow is output from the heat exchange outlet 1013A by driving the indoor fan. In this way, by operating the indoor heat exchanger and the indoor fan, it is possible to cool or heat the indoor air so that the indoor temperature reaches a temperature comfortable for the user.

[0028] The indoor unit 10A further includes a drive assembly 30A and an air deflector 40A, and the drive assembly 30A is provided within the first housing 101A. The air deflector 40A is provided at the heat exchange air outlet 1013A and includes at least one rotation shaft, which is provided at both ends of the air deflector 40A. The air deflector 40A is rotatable about the rotation shaft to open and close the heat exchange air outlet 1013A.

[0029] In the prior art, the air deflector is usually limited to a drive assembly, for example, a drive part of the drive assembly, and can only rotate in a single direction, for example, only upward or downward, which reduces the air flow range and angle of the heat exchange outlet, resulting in insufficient air flow effect.

[0030] In some embodiments, the width of the air deflector is increased, increasing the overall area, thereby increasing the area of ​​the heat exchange outlet corresponding to the air deflector, and the airflow range of the heat exchange outlet. However, a more functional drive assembly is required to drive the air deflector, which increases the volume, complexity, cost, installation difficulty, and reliability of the drive assembly.

[0031] To solve the above problems, some embodiments of the present disclosure provide an air conditioner 1. The air deflector of the air conditioner 1 has a large overall area and can rotate up and down, and the drive assembly has a high load-bearing capacity, which prevents a safety issue such as the air deflector falling due to insufficient torque when the drive assembly operates the air deflector to the upper and lower limit positions in the open state.

[0032] As shown in FIG. 3, the air conditioner 1 includes an indoor unit 10 that includes a heat exchange outlet 1013, a heat exchange inlet 1014, and an air direction plate 40.

[0033] In one embodiment of the present disclosure, the indoor unit 10 includes a first housing 101 and a base 102, and the base 102 includes a bottom wall 1021 and two side walls 1022 arranged opposite each other in the longitudinal direction of the bottom wall 1021 (the X direction in FIG. 3).

[0034] The indoor unit 10 further includes at least one drive assembly 30 provided in the first housing 101. For example, the at least one drive assembly 30 is provided on at least one of the two side walls 1022 of the base 102. When the air conditioner 1 includes two drive assemblies 30, the two drive assemblies 30 are provided on the two side walls 1022 of the base 102, respectively, and in this case, the two drive assemblies 30 are arranged symmetrically. This makes it possible to drive the opening and closing operation of the air deflector 40 more stably.

[0035] As shown in FIG. 4, in one embodiment of the present disclosure, the drive assembly 30 includes a second housing 31 mounted on the side wall 1022 of the base 102 .

[0036] In one embodiment of the present disclosure, the drive assembly 30 further includes a first transmission member 32 and a second transmission member 33, where the first transmission member 32 is rotatably connected within the second housing 31. The second transmission member 33 is rotatably connected to the first transmission member 32, and rotation of the first transmission member 32 can drive the second transmission member 33 to slide relative to the second housing 31.

[0037] As shown in FIG. 5, in one embodiment of the present disclosure, the second housing 31 includes a first transmission part 311 (eg, a chute).

[0038] The drive assembly 30 includes a first transmission rod 34 and a second transmission rod 35. One end of the first transmission rod 34 is slidably connected to the second transmission rod 35, and the other end is movably connected to a first position in the middle of the wind direction plate 40 in the width direction (V direction in FIG. 3 ).

[0039] In one embodiment of the present disclosure, the first transmission rod 34 includes a first shaft 341 (shown in FIG. 24 ), a second shaft 342, and a first transmission rod body 343. The first shaft 341 and the second shaft 342 are provided on opposite sides of the first transmission rod body 343 in the thickness direction, and the axes of the first shaft 341 and the second shaft 342 are coincident. The first transmission rod 34 is slidably connected to the first transmission part 311 of the second housing 31 via the first shaft 341, and is slidably connected to the second transmission rod 35 via the second shaft 342.

[0040] The second transmission rod 35 has one end fixedly connected to the first transmission member 32 and the other end slidably connected to the first transmission rod 34. In one embodiment of the present disclosure, the second transmission rod 35 includes a second transmission part 351 (e.g., a chute), which is provided at an end of the second transmission rod 35 away from the first transmission member 32, and the second shaft 342 of the first transmission rod 34 is slidably connected to the second transmission part 351 of the second transmission rod 35.

[0041] 6 and 7, in one embodiment of the present disclosure, the second housing 31 includes a first sub-housing 11 and a second sub-housing 12 that are connected to each other. The first transmission member 32 is movably connected to the first sub-housing 11 and is rotatable relative to the first sub-housing 11, and the first transmission part 311 is provided in the second sub-housing 12.

[0042] As shown in Figure 6, when the first transmission member 32 drives the second transmission rod 35 to rotate, the first axis 341 of the first transmission rod 34 slides into the first transmission part 311 of the second housing 31, and the second axis 342 slides into the second transmission part 351 of the second transmission rod 35, causing the second transmission rod 35 to push the wind deflector 40 to rotate.

[0043] 7 and 8, the wind direction vane 40 includes a first rotation shaft 41 and a second rotation shaft 42, which are respectively provided at both ends of the wind direction vane 40 in the width direction and configured to be mated and engaged with the second transmission member 33 and the wind direction vane 40. In one embodiment of the present disclosure, at least one of the first rotation shaft 41 and the second rotation shaft 42 is mated and engaged with the second transmission member 33 and the wind direction vane 40. It should be understood that when the second transmission rod 35 drives the first transmission member 32 to rotate, the second transmission member 33 can be engaged with the rotating shaft (first rotating shaft 41 or second rotating shaft 42) on one end side of the air deflector 40, thereby enabling the other end, where the rotating shaft (second rotating shaft 42 or first rotating shaft 41) that is not engaged with the second transmission member 33 of the air deflector 40 is located, to rotate toward the top plate 1011 of the first housing 101 or rotate away from the top plate 1011 of the first housing 101.

[0044] 9, in one embodiment of the present disclosure, when the air conditioner 1 operates in heating mode, the warm air discharged through the heat exchange outlet 1013 of the indoor unit 10 moves upward. In this case, the first transmission member 32 rotates counterclockwise in conjunction with the drive assembly 30, and the second transmission member 33 is driven by the first transmission member 32 to move toward the end of the air deflector 40 and engage with the first rotation shaft 41 or the second rotation shaft 42 of the air deflector 40, for example, the first rotation shaft 41. In this case, the air deflector 40 is rotatable around the first rotation shaft 41, and the second rotation shaft 42 is free. As a result, due to the interlocking action of the first transmission member 32, the first transmission rod 34, the second transmission rod 35, and the air deflector 40, the air deflector 40 is pushed to rotate clockwise around the first rotation axis 41 toward the top plate 1011 of the first housing 101, and at this time, the air blown out from the heat exchange outlet 1013 of the indoor unit 10 is guided by the air deflector 40 to the bottom of the indoor unit 10.

[0045] 10 , in one embodiment of the present disclosure, when the air conditioner 1 operates in cooling mode, cool air discharged from the heat exchange outlet 1013 of the indoor unit 10 moves downward. In this case, the first transmission member 32 rotates clockwise in conjunction with the drive assembly 30, and the second transmission member 33 is driven by the first transmission member 32 to move toward the other end of the air deflector 40 and engage with the first rotation shaft 41 or the second rotation shaft 42 of the air deflector 40, for example, the second rotation shaft 42. In this case, the air deflector 40 is rotatable around the second rotation shaft 42, and the first rotation shaft 41 is in a free state. As a result, due to the interlocking action of the first transmission member 32, the first transmission rod 34, the second transmission rod 35, and the air deflector 40, the air deflector 40 is pushed around the second rotation axis 42 to rotate counterclockwise away from the top plate 1011 of the first housing 101, and at this time, the air blown out from the heat exchange outlet 1013 of the indoor unit 10 is guided by the air deflector 40 to the top of the indoor unit 10.

[0046] Note that the direction of rotation of the first transmission member 32 in conjunction with the drive assembly 30 does not correspond to the direction of rotation of the air deflector 40 around its end portion that engages with the second transmission member 33. For example, when the air conditioner 1 operates in heating mode, the first transmission member 32 rotates clockwise in conjunction with the drive assembly 30, so that the air deflector 40 can be installed so that it rotates clockwise around its end portion that engages with the second transmission member 33, toward the top plate 1011 of the first housing 101. This enables the air blown out from the heat exchange outlet 1013 of the indoor unit 10 to be guided to the bottom of the indoor unit 10 by the air deflector 40.

[0047] Similarly, when the air conditioner 1 operates in cooling mode, the first transmission member 32 rotates counterclockwise in conjunction with the drive assembly 30, causing the air deflector 40 to rotate counterclockwise around its end that engages with the second transmission member 33, away from the top plate 1011 of the first housing 101. This allows the air blown out from the heat exchange outlet 1013 of the indoor unit 10 to be guided to the top of the indoor unit 10 by the air deflector 40.

[0048] It should be understood that when the at least one drive assembly 30 includes two or more drive assemblies 30, the rotation directions of the first transmission members 32 of different drive assemblies 30 may be opposite when the air conditioner 1 operates in the same mode. In this way, the drive assemblies 30 can drive the air deflector 40 to achieve up-and-down rotation, thereby satisfying the user's request for the airflow direction of the indoor unit 10 in the same mode. For example, as shown in FIG. 9, when the air conditioner 1 operates in cooling mode, the user can control the air deflector 40 to rotate upward.

[0049] In one embodiment of the present disclosure, the curved shape of the first transmission part 311 is set and a simulation analysis is performed to determine the movement trajectory of the wind direction vane 40. The change in the curvature at each point on the first transmission part 311 can change the opening / closing angular velocity of the wind direction vane 40 at each time.

[0050] It should be understood that if the opening and closing angular velocity of the wind deflector 40 at each time has already been determined, the curved shape of the first transmission part 311 and the curvature at each point on the first transmission part 311 can be inversely derived by logical relational operations.

[0051] 5, in one embodiment of the present disclosure, the rotation axis of the first transmission member 32 is defined as point A, the position of the common axis of the first axis 341 and the second axis 342 of the first transmission rod 34 is defined as point B, and the linear velocity of point B on the second transmission rod 35 is defined as V1. A first position in the middle of the air deflector 40 is defined as point C, and the axis of the rotation axis on one end of the air deflector 40 is defined as point D. For example, the axis of the first rotation axis 41 of the air deflector 40 is defined as point D. The linear velocity of point C, which is the first position in the middle of the air deflector 40, is defined as V2, and the distance between point D, which is the axis of the first rotation axis 41, and point C, which is the first position of the air deflector 40, is defined as R. DC The linear velocity V2 is R DC The intersection of the extension of line segment AB and the extension of line segment CD is defined as point O.

[0052] The distance between point A and point O is L OA Let the distance between point C and point O be L OC Let R be the distance between point A and point B. AB Let the distance between point B and point O be L OB and the angular velocity of the wind direction vane 40 rotating around the first rotation axis 41 is ω DC Let the distance between point B and point C be L BC and the angular velocity at which the first transmission member 32 rotates around the rotation axis is ω1.

[0053] In one embodiment of the present disclosure, ω DC , L BC , ω1 and R DC The value of L is preset and the measured value is OA and L OC By combining the values ​​of R and R and performing a logical relational operation, the R and R values ​​can be calculated when the wind direction vane 40 rotates to different positions around the first rotation axis 41. ABSince point A is a known point, it is possible to determine R when the wind direction plate 40 is rotated to a different position. AB Once the value of is determined, it is possible to obtain the positions of multiple points B. By connecting multiple positions through which point B passes, it is possible to obtain the curved shape of first transmission part 311 and the curvature at each point on first transmission part 311.

[0054] For example, when the wind direction plate 40 rotates, the first transmission member 32 rotates at a constant speed at a preset angular velocity ω1, and when the wind direction plate 40 rotates to a different position, the angular velocity ω DC Therefore, when the wind direction plate 40 rotates to an arbitrary position, the corresponding position of the second transmission member 33 can be predicted. OA and L OC and measure the value of ω when the wind deflector 40 is rotated to different positions. DC , L BC , ω1, R DC , L OA and L OC By introducing the value of into the logical relationship, the logical relationship calculation can be used to calculate the corresponding R when the wind direction plate 40 is rotated to different positions. AB The value of V2 is determined, and the positions of multiple points B are obtained. Furthermore, based on the positions of multiple points B, the curved shape of the first transmission part 311 and the curvature at each point on the first transmission part 311 are determined. The logical relationship is V2=ω DC ×R DC , V2=ω BC ×L OC , V1=ω BC ×L OB , V1=ω1×R AB , L OA =L OB +R AB is.

[0055] The second transmission rod 35, while interlocking with the first transmission member 32, pushes the end of the first transmission rod 34, where the first shaft 341 and the second shaft 342 are provided, and moves the end while being restricted by the first transmission part 311. The angular velocity of the first transmission member 32 in a uniform rotation is ω1, and the curvature of the curve of the first transmission part 311 is a variable that changes moment by moment while the point B is moving, so R AB The magnitude of is the amount of change over time. By reflecting in the transmission of the moving speed of the drive assembly 30, the instantaneous angular velocity ω of the wind direction vane 40 at any time DC It is possible to limit the distance between the first transmission part 311 and the first drive shaft 312, and further to inversely estimate the curvature of the curve of the first transmission part 311. This contributes to the design of a technical form for realizing a product configuration based on the parameter requirements at the customer end of the product.

[0056] 8, when the airflow direction plate 40 closes the heat exchange outlet 1013, the longitudinal direction of the first power transmission rod 34 is perpendicular to the airflow direction plate 40, that is, the line segment AB and the perpendicular line of the linear velocity V2 are aligned on the same straight line. DC , L BC , ω1 and R DC Since the value of is set in advance, the position of point A, which is the rotation axis of the first transmission member 32 in the longitudinal direction of the first transmission rod 34, is determined.

[0057] 22 and 24 , in one embodiment of the present disclosure, the drive assembly 30 further includes a drive member 36 provided in the first housing 101. The drive member 36 includes a drive member body 361 and a drive motor 362. The drive member body 361 is operatively connected to the first transmission member 32. The drive motor 362 includes an output shaft 3621 and is fixedly connected to the drive member body 361 via the output shaft 3621.

[0058] In one embodiment of the present disclosure, the driving member body 361 includes a receiving portion 3611 arranged to be connected to the output shaft 3621 of the driving motor 362. The receiving portion 3611 is, for example, a groove provided in the rotation axis of the driving member body 361. The driving member body 361 and the first transmission member 32 are both gears.

[0059] In one embodiment of the present disclosure, the interlocking drive member body 361 rotates about its own rotation axis in conjunction with the rotation of the output shaft 3621 of the drive motor 362, and the first transmission member 32 rotates about its own rotation axis in conjunction with the rotation of the drive member body 361. As a result, the second transmission rod 35 rotates synchronously in conjunction with the rotation of the first transmission member 32, causing the second shaft 342 of the first transmission rod 34 to slide into the second transmission part 351 and pushing the first shaft 341 to slide into the first transmission part 311. The end of the first transmission rod 34 connected to the air deflector 40 pushes the air deflector 40 to rotate, and the air deflector 40 rotates clockwise or counterclockwise about its own rotation axis connected to the first transmission rod 34, thereby opening the air deflector 40 upward or downward to blow air.

[0060] As shown in FIG. 24, in one embodiment of the present disclosure, the air conditioner 1 further includes a torque sensor and a control device, and the torque sensor is arranged to detect the torque of the output shaft 3621 of the drive motor 362.

[0061] When the air conditioner 1 operates stably, the output of the drive motor 362 is constant, and the torque sensor determines whether the torque of the drive motor 362 is equal to or less than a preset threshold. Here, the preset threshold is the threshold when the drive motor 362 is operating normally and is smaller than the rated torque of the drive motor 362. In one embodiment of the present disclosure, the preset threshold can be set to less than half the rated torque of the drive motor 362 to ensure normal operation of the drive motor 362 and prevent damage to the drive motor 362 due to excessive torque.

[0062] If the torque of the output shaft 3621 is greater than a preset threshold, i.e., if the resistance experienced by the output shaft 3621 when driving the first transmission member 32 is large, it indicates that the curvature of the curve in the first transmission part 311 corresponding to the first shaft 341 is changing rapidly. In this case, the position in the first transmission part 311 of the second housing 31 corresponding to the axis of the first shaft 341 of the first transmission rod 34 (i.e., point B in FIG. 8) is moved a preset distance in a direction approaching the rotation axis of the first transmission member 32.

[0063] The above process is repeated until the torque sensor detects the torque of the output shaft 3621 corresponding to the first shaft 341 at each position in the first transmission part 311.

[0064] The power transmission connection relationship between the first transmission member 32 and the drive member body 361 remains unchanged, but the curvature of the first transmission part 311 of the second housing 31 changes. Therefore, the driving force required for the first shaft 341 of the first transmission rod 34 to slide within the first transmission part 311 changes.

[0065] In one embodiment of the present disclosure, as shown in Fig. 8, when point B is moved by a predetermined distance in a direction approaching the rotation axis of first transmission member 32, the position of adjacent point B on the curve of first transmission part 311 can be moved in a direction approaching point A, and the moving distance is set to be less than the predetermined distance so that the curvature on the curve of first transmission part 311 changes continuously. By moving point B by the predetermined distance in a direction approaching point A, R AB That is, reducing the value of R AB It is possible to shorten the force arm of R. AB By shortening the force arm, the driving force of the second transmission rod 35 relative to the axis of the first shaft 341 of the first transmission rod 34 (i.e., point B) increases, thereby increasing the driving force of the first transmission rod 34 relative to the wind deflector 40, improving the load-bearing capacity of the drive assembly 30 and improving the reliability of the rotational operation of the wind deflector 40.

[0066] The end of the second transmission part 351 that is farther away from the rotation axis of the first transmission member 32 (i.e., point A) is defined as point L, and the distance between point L and point A is defined as L. LA In one embodiment of the present disclosure, L LA The value of is N times the length of the second transmission part 351, for example, twice the length of the second transmission part 351, which can improve the reliability of use of the drive assembly 30.

[0067] In one embodiment of the present disclosure, the distance R AB L LA =Z×R AB When L LA The value of R AB When the rotation angle of the first transmission rod 34 is equal to Z times the value of R, when the first transmission rod 34 is rotated by the same angle, the driving force that the axis of the first shaft 341 receives from the second transmission rod 35 increases by Z times. AB It is possible to shorten the length of the first shaft 341 of the first transmission rod 34 and increase the driving force of the second transmission rod 35 relative to the first shaft 341 of the first transmission rod 34, thereby improving the operational reliability and stability of the drive assembly 30.

[0068] In one embodiment of the present disclosure, the dimensions and shape of the curved curvature of the first transmission part 311 are detected and adjusted so that the curved curvature of the first transmission part 311 meets operational reliability when driving the first transmission member 32 to rotate by the drive assembly 30.

[0069] 8 and 9, the first transmission part 311 of the second housing 31 includes a plurality of arc-shaped grooves connected in series, and ends of at least two of the plurality of arc-shaped grooves are connected in a tangential direction, thereby reducing the resistance of the first transmission part 311 to the first shaft 341 of the first transmission rod 34 and increasing the smoothness of operation of the drive assembly 30.

[0070] The two end points of the arc shape of the first transmission part 311 are point H and point G, respectively. In the first transmission part 311, the end connection points of the multiple arc-shaped grooves along the direction extending from point H to point G are defined as point I, point J, point K, point E, and point F, respectively. The first transmission part 311 includes arc portions HI, IJ, JE, EF, and FG, which are connected in sequence. Arc portion JE is located in the middle of the first transmission part 311, and point K is the midpoint of arc portion JE, so point K is the point on the first transmission part 311 that is farthest from the rotation axis of the first transmission member 32.

[0071] In one embodiment of the present disclosure, the first transmission part 311 satisfies at least one of the following requirements: the arc section HI is a perfect circle, the arc section JE is a perfect circle, or the arc section FG is a perfect circle, thereby reducing the effect of the curve curvature of the first transmission part 311 on the torque of the output shaft 3621 of the drive motor 362 and increasing the smoothness of operation of the drive assembly 30.

[0072] In one embodiment of the present disclosure, the length of the line segment between the arc portion HI and point A, which is the rotation axis of the first transmission member 32, is defined as R. HA The length of the line segment between the arc JE and point A is defined as R JA The length of the line segment between the arc FG and point A is defined as R FA and R HA , R FA and R JA R HA =R FA <R JA As a result, when the first shaft 341 rotates from point K to both ends of the first transmission part 311, if the driving force of the driving motor 362 is constant, the driving force that the first transmission rod 34 receives from the second transmission rod 35 increases, ensuring reliable operation of the drive assembly 30.

[0073] 10 , an angle ∠HAI is formed between line segments AH and AI, an angle ∠JAE is formed between line segments AJ and AE, and an angle FAG is formed between line segments AF and AG. In one embodiment of the present disclosure, the first transmission part 311 is set to satisfy at least one of 0°≦∠HAI≦25°, 10°≦∠JAE≦25°, or 0°≦∠FAG≦25°. This improves the reliability of the operation of the first shaft 341 of the first transmission rod 34 within the first transmission part 311 and makes it possible to avoid operational interruptions when the first shaft 341 operates within the first transmission part 311.

[0074] In one embodiment of the present disclosure, when the first shaft 341 is disposed within the arc portion JE, a first gap (e.g., a first gap between the first shaft 341 and the width of the arc portion JE) exists. That is, the gap between the both sides of the first shaft 341 in the width direction of the arc portion JE and the width of the arc portion JE is defined as the first gap, and the first gap is, for example, 0.2 mm. This prevents operational interruptions when the first shaft 341 slides within the arc portion JE, thereby improving the smooth operation of the drive assembly 30.

[0075] When the first shaft 341 is disposed within the arc portion HJ, a second gap (e.g., a second gap) exists between the first shaft 341 and the width of the arc portion HJ. That is, the gap between the width of the arc portion HJ and both sides of the first shaft 341 in the width direction of the arc portion HJ is defined as the second gap. In one embodiment of the present disclosure, the second gap is smaller than the first gap, e.g., 0.1 mm. This prevents operational interruptions when the first shaft 341 slides within the arc portion HJ, improving the smooth operation of the drive assembly 30.

[0076] When the first shaft 341 is disposed within the arc portion EG, a third gap (e.g., a third gap) exists between the first shaft 341 and the width of the arc portion EG. That is, the gap between the both sides of the first shaft 341 in the width direction of the arc portion EG and the width of the arc portion EG is defined as the third gap. In one embodiment of the present disclosure, the third gap is smaller than the first gap, e.g., 0.1 mm. This prevents operational interruptions when the first shaft 341 slides within the arc portion EG, improving the smooth operation of the drive assembly 30.

[0077] It should be understood that since the driving force required by the first axis 341 is greatest at point K, by making the first gap larger than either the second gap or the third gap, it is possible to avoid interruption of operation of the first axis 341 within the arc section JE.

[0078] 8 and 9, line segments AK and AH define angle KAH, which is, for example, 120°. When first shaft 341 moves from point K to point H along first transmission part 311, air deflector 40 moves from a closed state to an open state in which it opens downward, and at this time, the maximum rotation angle of air deflector 40 is, for example, 75°.

[0079] 9, the angle KAG is defined by the line segments AG and AK, and is, for example, 150°. When the first shaft 341 moves from point K to point G along the first transmission part 311, the air deflector 40 moves from a closed state to an open state where it opens upward, and at this time, the maximum rotation angle of the air deflector 40 is, for example, 80°.

[0080] Furthermore, by making the maximum rotation angle at which the air deflector 40 opens upward greater than the maximum rotation angle at which the air deflector 40 opens downward, it is possible to increase the range of cool air blown when the air deflector 40 opens upward, thereby preventing the cool air from being blown onto the ceiling of the room and preventing the air blowing from being obstructed and affecting the air blowing efficiency.

[0081] Since the indoor unit 10 is generally installed at the top of the indoor space, it should be understood that when the air deflector 40 opens downward, the airflow downward from the indoor unit 10 is not obstructed, and the angle at which the air deflector 40 opens downward can be set to be smaller than the angle at which the air deflector 40 opens upward.

[0082] 11 , in one embodiment of the present disclosure, the second housing 31 further includes a first rotating portion 312 and a second rotating portion 313. The first rotating portion 312 and the second rotating portion 313 are provided at both ends of the second housing 31 in a direction parallel to the longitudinal direction of the second transmission member 33, and the first rotating portion 312 is aligned with the first rotating shaft 41 of the wind deflector 40, and the second rotating portion 313 is aligned with the second rotating shaft 42 of the wind deflector 40.

[0083] In one embodiment of the present disclosure, at least a portion of the first rotating part 312 and the second rotating part 313 has an open structure, which can prevent operational disruption due to thermal expansion and contraction of the material of the drive assembly 30 during rotation of the wind deflector 40.

[0084] In one embodiment of the present disclosure, the wind deflector 40 further includes a first engaging portion 43 provided with a first rotation shaft 41 and a second engaging portion 44 provided with a second rotation shaft 42. The first engaging portion 43 is engaged within the first rotating portion 312 by mating with the second transmission member 33, and the second engaging portion 44 is engaged within the second rotating portion 313 by mating with the second transmission member 33. As a result, downward rotation of the wind deflector 40 is achieved by engaging the first engaging portion 43 with the first rotating portion 312, and upward rotation of the wind deflector 40 is achieved by engaging the second engaging portion 44 with the second rotating portion 313.

[0085] When the first attachment portion 43 is attached within the first rotating portion 312, the air deflector 40 rotates around the first rotation axis 41 on the first attachment portion 43. In this case, the combination of the first attachment portion 43 and the first rotating portion 312 allows the air deflector 40 to swing relative to the heat exchange outlet 1013. As a result, when the air conditioner 1 operates in cooling mode, the air deflector 40 can rotate downward; that is, the airflow range formed between the air deflector 40 and the heat exchange outlet 1013 faces upward (as shown in FIG. 10 ), making it possible to realize an upward airflow design for the air conditioner 1.

[0086] When the second attachment portion 44 is fitted within the second rotating portion 313, the air deflector 40 can rotate around the second rotation axis 42 on the second attachment portion 44. In this case, the arrangement of the second attachment portion 44 and the second rotating portion 313 allows the air deflector 40 to swing relative to the heat exchange outlet 1013. As a result, when the air conditioner 1 operates in heating mode, the air deflector 40 can rotate upward; that is, the airflow range formed between the air deflector 40 and the heat exchange outlet 1013 faces downward (as shown in FIG. 9 ), making it possible to realize a downward airflow design for the air conditioner 1.

[0087] 18 and 23, in one embodiment of the present disclosure, the wind direction vane 40 further includes a first hook portion 45 (e.g., a claw portion). The first hook portion 45 is provided on at least one of the first attachment portion 43 and the second attachment portion 44. When the wind direction vane 40 includes two first hook portions 45, the two first hook portions 45 are connected to the first rotation shaft 41 and the second rotation shaft 42, respectively.

[0088] The second housing 31 further includes a second hook portion 316 (e.g., a claw portion), and the second hook portion 316 is provided in at least one of the first rotating portion 312 and the second rotating portion 313. The first hook portion 45 and the second hook portion 316 selectively abut against each other; that is, when the first hook portion 45 of the wind direction plate 40 rotates above the second hook portion 316, the first hook portion 45 abuts against the second hook portion 316. In one embodiment of the present disclosure, the second hook portion 316 and the first hook portion 45 are provided corresponding to each other. When the second housing 31 includes two second hook portions 316, the two second hook portions 316 are provided on the sides of the first rotating portion 312 and the second rotating portion 313 that are close to each other, respectively. For example, the second hook portion 316 in the first rotating portion 312 is provided on the side of the first rotating portion 312 that is close to the second rotating portion 313, and the second hook portion 46 in the second rotating portion 313 is provided on the side of the second rotating portion 313 that is close to the first rotating portion 312.

[0089] In one embodiment of the present disclosure, the side of first hook portion 45 connected to the corresponding rotation axis (e.g., first rotation axis 41 or second rotation axis 42) is defined as the long side, and the side away from the corresponding rotation axis is defined as the short side or apex. This makes it possible to improve the structural strength of first hook portion 45, facilitate contact between first hook portion 45 and second hook portion 316, and improve the structural stability of first hook portion 45 and second hook portion 316 after contact.

[0090] As a result, the first hook portion 45 is provided on at least one of the first attachment portion 43 and the second attachment portion 44, and the second hook portion 316 is provided on at least one of the first rotating portion 312 and the second rotating portion 313. Therefore, when the first attachment portion 43 and the first rotating portion 312 abut and position the airflow direction vane 40, or when the second attachment portion 44 and the second rotating portion 313 abut and position the airflow direction vane 40, the airflow direction vane 40 can be operated to its limit position. That is, in this case, the angle between the airflow direction vane 40 and the second transmission member 33 is maximized. This realizes a position limit for the opening angle of the airflow direction vane 40, contributing to the reciprocating movement of the airflow direction vane 40 and increasing the airflow range and angle of the indoor unit 10.

[0091] 17 and 18 , in one embodiment of the present disclosure, the second housing 31 further includes a guide surface 314, which is provided in at least one of the first rotating portion 312 and the second rotating portion 313, and is arranged to provide a guiding function during the rotation of the wind direction vane 40. The first hook portion 45 rotates along the extending direction of the guide surface 314 until it abuts against the second hook portion 316.

[0092] In one embodiment of the present disclosure, when the air deflector 40 is rotated open from the closed state and the angle between the air deflector 40 and the longitudinal direction of the second transmission member 33 reaches a first predetermined angle, the first hook portion 45 abuts the second hook portion 316, and the second hook portion 316 receives force from the rotation axis of the air deflector 40 while catching the first hook portion 45. The air deflector 40 continues to be pushed by the first transmission rod 34 so as to rotate until it reaches the second predetermined angle.

[0093] When the airflow direction plate 40 rotates from the first predetermined angle to the second predetermined angle, the first hook portion 45 and the second hook portion 316 maintain a state of abutting against each other.

[0094] When the airflow direction plate 40 rotates to the second predetermined angle, the first hook portion 45 comes into contact with the second hook portion 316, and the second hook portion 316 receives the pressure generated during the rotation of the airflow direction plate 40. The second hook portion 316 contributes to improving the reliability of the indoor unit. For example, even if the second power transmission member 33 is torn at the position supporting the airflow direction plate 40, or even if the second power transmission member 33 is directly pulled out, the second hook portion 316 continues to support the airflow direction plate 40 by engaging with the first hook portion 45. This makes it possible to improve the reliability of the indoor unit 10 while ensuring a wide air distribution range of the indoor unit 10.

[0095] 12, 13, and 23, in one embodiment of the present disclosure, the second transmission member 33 includes a block portion 331 (e.g., a baffle plate), and the block portion 331 is provided at both ends of the second transmission member 33 in the longitudinal direction. The block portion 331 is arranged to completely or partially block the first rotating portion 312 or the second rotating portion 313, thereby restricting the position of the first rotating shaft 41 within the first rotating portion 312, or restricting the position of the second rotating shaft 42 within the second rotating portion 313. As a result, the first engaging portion 43 rotates around the first rotating shaft 41 within the first rotating portion 312, or the second engaging portion 44 rotates around the second rotating shaft 42 within the second rotating portion 313, thereby realizing the rotation of the wind direction vane 40.

[0096] The end of the block portion 331 that faces away from the second transmission member 33 is chamfered, and the block portion 331 can come into contact with the first rotating shaft 41 or the second rotating shaft 42 at a constant gradient. This ensures that the second transmission member 33 can limit the position of the first rotating shaft 41 or the second rotating shaft 42 more gently.

[0097] In this way, a mutual reinforcing effect can be exerted between the block portion 331 and the second hook portion 316, and the second hook portion 316 can share the pressure applied from the first hook portion 45 to the second transmission member 33, thereby improving the reliability of use of the block portion 331 and the second hook portion 316.

[0098] 24 , in one embodiment of the present disclosure, the drive assembly 30 further includes a third transmission member 37. The third transmission member 37 is provided between the first transmission member 32 and the second transmission member 33, and is operably connected to the first transmission member 32 and the second transmission member 33, respectively. The rotation of the first transmission member 32 can drive the third transmission member 37 to rotate, and the rotation of the third transmission member 37 can drive the second transmission member 33 to move to one end of the wind direction of the wind deflector 40, and finally, the second transmission member 33 is engaged with a rotation shaft at one end of the wind deflector 40.

[0099] 12, the second transmission member 33 further includes a second toothed portion 333. The second toothed portion 333 is the transmission input structure of the second transmission member 33, and the tooth tips of the standard teeth of the second toothed portion 333 are chamfered, that is, the corners of the right angles of the tooth tips of the standard teeth are chamfered into curved surfaces. This prevents the tooth tips of the second toothed portion 333 from colliding with the third transmission member 37 during use, causing mutual damage, and contributes to improving the transmission stability of the second transmission member 33.

[0100] As shown in FIG. 19, the third transmission member 37 is, for example, a slot wheel, and includes spaced apart first tooth portions 371 and blending holes 372, and the first tooth portions 371 mesh with the second tooth portions 333.

[0101] In one embodiment of the present disclosure, the rotation axis of the drive member body 361 of the drive member 36 and the rotation axis of the third transmission member 37 are coaxially arranged. The drive member body 361 and the third transmission member 37 are movably connected, and the third transmission member 37 does not directly drive the rotation of the drive member body 361 to rotate. By setting the drive member body 361 and the third transmission member 37 to be coaxially stacked, the space occupied by the drive assembly 30 in the second housing 31 can be reduced.

[0102] In a further embodiment of the present disclosure, the rotation axis of the drive member body 361 and the rotation axis of the third transmission member 37 do not have to be coaxial. Thus, by setting the rotation axis of the drive member body 361 and the rotation axis of the third transmission member 37 coaxially, it is possible to avoid restrictions on the parameters of the gear transmission system between the first transmission member 32, the third transmission member 37, and the drive member body 361, and it is possible to adapt the drive assembly 30 to various parameter requirements.

[0103] 12, in one embodiment of the present disclosure, the second transmission member 33 further includes a fourth engaging portion 332, and the fourth engaging portion 332 is provided on at least one of both ends in the longitudinal direction of the second transmission member 33. As shown in FIG. 14, in one embodiment of the present disclosure, the second housing 31 further includes at least one third engaging portion 315, and the at least one third engaging portion 315 is provided on at least one of both ends of the second housing 31 in a direction parallel to the longitudinal direction of the second transmission member 33. The third engaging portion 315 and the fourth engaging portion 332 selectively engage with each other while the second transmission member 33 slides. That is, after the third fastening portion 315 is inserted into the fourth fastening portion 332, the second transmission member 33 is fixed to the second housing 31 by the engagement of the third fastening portion 315 and the fourth fastening portion 332, thereby fixing the relative position of the second transmission member 33 and the second housing 31, and the block portion 331 can always be engaged with the first rotating portion 312 or the second rotating portion 313. This makes it possible to connect the second transmission member 33 and the second housing 31 so as to fix the second transmission member 33, and improves the load strength that the block portion 331 and the first rotating portion 312 or the second rotating portion 313 receive from the wind direction plate 40.

[0104] In one embodiment of the present disclosure, the third engaging portion 315 is a slot, and the fourth engaging portion 332 is a hook. In another embodiment of the present disclosure, the third engaging portion 315 is a hook, and the fourth engaging portion 332 is a slot. As a result, the second transmission member 33 and the second housing 31 are fixed together by the engagement between the hook and the slot.

[0105] 20, in one embodiment of the present disclosure, the first transmission member 32 includes a connecting portion 321 (e.g., a mixing column), and the connecting portion 321 and the mixing hole 372 of the third transmission member 37 are selectively mixed. As a result, the connecting portion 321 follows the rotation of the first transmission member 32, and rotates until it slides into the mixing hole 372 and mixes, and can be linked to rotate the third transmission member 37.

[0106] In one embodiment of the present disclosure, the first transmission member 32 includes a first sub-transmission member 322, a second sub-transmission member 323, and a third tooth portion 324, and the first sub-transmission member 322 and the second sub-transmission member 323 are coaxially stacked. The third tooth portion 324 is provided on the periphery of the first sub-transmission member 322, and the connecting portion 321 is provided on the second sub-transmission member 25. This allows the connecting portion 321 and the third tooth portion 324 to be positioned in different planes parallel to the second housing 31, making it possible to avoid interference between the connecting portion 321 and the third tooth portion 324.

[0107] For example, the first sub-transmission member 322 and the second sub-transmission member 323 are integrally molded, which can reduce costs and improve the reliability of use of the drive assembly.

[0108] The third transmission member 37 includes at least one blending surface 373, and the at least one blending surface 373 is recessed toward the axis of the third transmission member 37. The at least one blending surface 373 is provided between the first tooth portion 371 and the blending hole 372. In one embodiment of the present disclosure, when the third transmission member 37 includes two blending surfaces 373, the two blending surfaces 373 are provided on both sides of the blending hole 372, respectively.

[0109] In one embodiment of the present disclosure, the first transmission member 32 further includes an engaging portion 325 (e.g., a protrusion), which is provided around the edge of the second sub-transmission member 323. When the first transmission member 32 rotates clockwise or counterclockwise to a predetermined angle, the engaging portion 325 of the first transmission member 32 engages with the mating surface 373 of the third transmission member 37. For example, when the connecting portion 321 slides out of the mating hole 372 of the third transmission member 37, the engaging portion 325 engages with the mating surface 373, restricting the rotation of the third transmission member 37. At the same time, as the first transmission member 32 continues to rotate clockwise or counterclockwise, the engaging portion 325 slides against the mating surface 373, preventing the third transmission member 37 from rotating accordingly, thereby realizing a restriction on the rotation of the third transmission member 37.

[0110] In one embodiment of the present disclosure, when the connecting portion 321 slides in the blending hole 372 in a direction closer to the rotation axis of the third transmission member 37, the angular velocity of rotation of the third transmission member 37 increases. When the connecting portion 321 slides from the blending hole 372 in a direction away from the rotation axis of the third transmission member 37, the angular velocity of rotation of the third transmission member 37 decreases.

[0111] When the airflow direction vane 40 closes the heat exchange outlet 1013, the distance between the connecting portion 321 and the rotation axis of the third transmission member 37 is minimized. That is, when the airflow direction vane 40 rotates from a state in which the heat exchange outlet 1013 is closed to open the heat exchange outlet 1013, the angular velocity of rotation of the third transmission member 37 is maximized. That is, when the operating angle of the first transmission member 32 is small, the third transmission member 37 can rotate through a large angle, and the engaging portion 325 can be engaged with the engaging surface 373 of the third transmission member 37 to complete self-locking. Furthermore, because the rotation angle of the third transmission member 37 is large, the sliding displacement distance of the second transmission member 33 relative to the third transmission member 37 is large. In other words, the second transmission member 33 can be operated until it engages with the first rotating shaft 41 or the second rotating shaft 42 of the wind deflector 40 immediately after the first transmission member 32 has operated at a small angle, and the first engaging portion 43 or the second engaging portion 44 of the wind deflector 40 can be engaged with the first rotating portion 312 or the second rotating portion 313, respectively.

[0112] In this case, the stroke by which the first transmission member 32 drives the first transmission rod 34 is small, and the cooperation between the rapid retraction / retraction movement mechanism and the extension / retraction delay movement mechanism is extremely advantageous in maintaining the engagement position of the first attachment part 43 or the second attachment part 44 of the air deflector 40. This generates a phase difference in the movement timing of the two movement mechanisms, ensuring that the air deflector 40 rotates by a small angle after the second transmission member 33 engages with the first attachment part 43 or the second attachment part 44, further ensuring the reliability of the movement mechanism of the air deflector 40 and avoiding the problem of the air deflector 40 rotating to detach from the first rotation part 312 or the second rotation part 313 before the second transmission member 33 reaches the engagement position.

[0113] As shown in FIG. 24, the driving member body 361 is mated with the third tooth portion 324 on the first sub-transmission member 322 to realize a transmission-enabled connection between the driving member 36 and the first transmission member 32.

[0114] In one embodiment of the present disclosure, the second transmission member 33 and the third transmission member 37 are operably connected, so that the second transmission member 33 also moves linearly during rotation of the third transmission member 37. The first transmission member 32 continues to rotate until the engagement portion 325 engages with the engagement surface 373, and when the third transmission member 37 is locked, the second transmission member 33 is also locked to the third transmission member 37 and its position is limited. In this case, the wind deflector 40 is in an open state and slides until the first hook portion 45 on the first attachment portion 43 or the first hook portion 45 on the second attachment portion 44 engages with the second hook portion 46.

[0115] In this way, by restricting the position by mating the engaging portion 325 with the mating surface 373, it is possible to prevent the second transmission member 33 from moving in the sliding direction of the second transmission member 33, and further to prevent the first engagement portion 43 of the second transmission member 33 from coming off the first hook portion 45, and the second engagement portion 44 of the second transmission member 33 from coming off the second hook portion 46.

[0116] Furthermore, by mating the engagement portion 325 on the first transmission member 32 with the mating surface 373 on the third transmission member 37, it is possible to limit the degree of freedom of the second transmission member 33 in the sliding direction of the second transmission member 33, and the second position limiting portion 335 and the third position limiting portion 336 are also able to limit the degree of freedom of the second transmission member 33 in the sliding direction of the second transmission member 33. In this way, it is possible to prevent problems such as backward movement of the second transmission member 33 that has reached the target position and reduced locking reliability of the second transmission member 33, which are caused by play between the second toothed portion 333 of the second transmission member 33 and the first toothed portion 371 of the third transmission member 37 when they mesh.

[0117] 20 , in one embodiment of the present disclosure, the engagement portion 325 on the second sub-transmission member 323 of the first transmission member 32 includes a second blending portion 326, which is, for example, a groove recessed toward the rotation axis of the first transmission member 32. The connection portion 321 is provided within the second blending portion 326.

[0118] 21 , the rotation of the first transmission member 32 causes the connecting part 321 to be blended into the blending hole 372. In this way, the rotation of the first transmission member 32 causes the connecting part 321 to push and rotate the third transmission member 37. Note that the connecting part 321 first slides in the blending hole 372 in a direction approaching the rotation axis of the third transmission member 37, and then slides in a direction away from the rotation axis of the third transmission member 37, and is removed from the blending hole 372.

[0119] The point at which the connection portion 321 rotates until it first comes into contact with the third transmission member 37 is defined as the first combination point M, the point at which the connection portion 321 rotates until it separates from the third transmission member 37 is defined as the second combination point N, and the rotation angle at which the connection portion 321 slides from point M to point N is defined as ∠MAN.

[0120] As shown in FIG. 10, both ends of the first transmission part 311 are point H and point G, respectively, and the angle that the first shaft 341 moves from point H to point G is defined as ∠HAG.

[0121] In one embodiment of the present disclosure, ∠MAN and ∠HAG satisfy 8≦∠HAG / ∠MAN≦12, thereby avoiding an insufficient depth for the connecting portion 321 of the first transmission member 32 to slide into the compounding hole 372 of the third transmission member 37 due to an angle of ∠MAN being too small, or an insufficient driving force and contact area from the first transmission member 32 to the third transmission member 37 due to mold clearance or product dimensional tolerances. This ensures that the stroke of the connecting portion 321 of the first transmission member 32 sliding through the compounding hole 372 of the third transmission member 37 meets the requirements for the driving force and contact area from the first transmission member 32 to the third transmission member 37, and ensures the operational reliability of the drive assembly 30. It should be noted that when the value of ∠HAG / ∠MAN is in [8, 12], as the value of ∠HAG / ∠MAN increases, the reaction speed of the drive assembly 30 increases and the structural reliability decreases.

[0122] In one embodiment of the present disclosure, the rotation axis of the third transmission member 37 is defined as point P, the distance from the center of the connecting portion 321 to the rotation axis of the first transmission member 32 is defined as R1, and the distance from the center of the connecting portion 321 to the rotation axis of the second transmission member 33 is defined as R2. The distance from the rotation axis of the first transmission member 32 to the rotation axis of the second transmission member 33 is defined as R3. R1, R2, and R3 satisfy the equation R3 = R1 × cos(∠MPN / 2) + R2 × (∠MAN / 2).

[0123] When the airflow direction plate 40 rotates from the closed state and opens to the maximum angle, the sliding stroke of the second transmission member 33 is defined as Y, and Y satisfies Y = 2πr × [(∠MPN / 2) / 360°]. In this way, by predefining the sliding stroke of the second transmission member 33, the airflow direction plate 40 can be opened to the maximum angle, which contributes to increasing the air blowing range of the indoor unit 10.

[0124] 12 , the second transmission member 33 includes a second position limiting portion 335 and a third position limiting portion 336, which are provided at both longitudinal ends of the second transmission member 33 and selectively abut against both ends of the second housing 31. When the second position limiting portion 335 slides until it abuts against the end of the second housing 31, it serves as a position limit for the second transmission member 33 and prevents the second transmission member 33 from sliding further, thereby preventing the second transmission member 33 from penetrating and escaping the second housing 31 due to excessive sliding displacement and limiting the operation of the drive assembly 30 due to the space outside the second housing 31.

[0125] In one embodiment of the present disclosure, referring to FIG. 14, the second transmission member 33 further includes a first position limiting portion 334, which is, for example, a slot.

[0126] The second housing 31 further includes a position limiting rod 317. The position limiting rod 317 is configured as a long straight rod and is arranged to fit into the first position limiting portion 334 of the second transmission member 33, thereby restricting the translational freedom and rotational freedom of the second transmission member 33 in the vertical direction, and the second transmission member 33 is slidable along the longitudinal direction of the position limiting rod 317. When the wind direction vane 40 is in the closed state, the position limiting rod 317 is located in the middle of the first position limiting portion 334.

[0127] 14, the length of the position limiting rod 317 is defined as L1, the length of the first position limiting portion 334 is defined as L2, and L1 and L2 satisfy the relationship L2 > L1. That is, when the first shaft 341 slides to one of the ends of the first transmission portion 311, both longitudinal ends of the position limiting rod 317 are spaced apart from the first position limiting portion 334. This prevents the position limiting rod 317 from limiting the sliding distance of the second transmission member 33, and avoids the problem of the second transmission member 33 not being able to engage with the first rotation shaft 41 or the second rotation shaft 42 of the wind direction plate 40 due to an insufficient sliding distance of the second transmission member 33.

[0128] When the first shaft 341 slides to the longitudinal end of the first transmission part 311, the second transmission member 33 engages the first rotating shaft 41 or the second rotating shaft 42 of the wind direction vane 40 within the first rotating part 312 or the second rotating part 313, for example, engaging the first rotating shaft 41 within the first rotating part 312. In this case, the first rotating shaft 41 can abut against the second transmission member 33. The second transmission member 33 provides a supporting force for the first rotating shaft 41.

[0129] In one embodiment of the present disclosure, the block portion 331 includes two support points 3311, which are points at which the first rotating shaft 41 or the second rotating shaft 42 abuts against the second transmission member 33, and are respectively provided at both ends in the longitudinal direction of the block portion 331. The distance between the support points 3311 at both ends of the second transmission member 33 is defined as L3, and the length of the second transmission member 33 is defined as L4. When the second transmission member 33 extends from the end support points 3311 in a direction away from the position limiting rod 317, L3 and L4 satisfy L4 > L3.

[0130] In one embodiment of the present disclosure, the relationship between the lengths L1 and L4 satisfies 2L1≦L4≦3L1. In this way, it is possible to ensure a sufficient sliding stroke in the longitudinal direction of the second transmission member 33 to achieve engagement between the second transmission member 33 and the airflow direction plate 40, and it is also possible to avoid poor engagement with the airflow direction plate 40 due to an excessively large sliding stroke, thereby improving the guide function of the second transmission member 33.

[0131] 15 , the distance between the axes of the first rotation shaft 41 and the second rotation shaft 42 of the air deflector 40 is L5, and when the air deflector 40 is in the closed state, the length L4 of the second transmission member 33 is equal to or greater than the distance L5 between the axes of the rotation shafts located at both ends of the second transmission member 33. In this manner, the air deflector 40 can effectively abut against the second transmission member 33 in the closed state, and it is possible to prevent the first rotation shaft 41 or the second rotation shaft 42 of the air deflector 40 from coming off the first housing 101. Furthermore, when the air deflector 40 rotates, the second transmission member 33 slides, thereby engaging the first rotation shaft 41 or the second rotation shaft 42 of the air deflector 40 with the first housing 101, preventing the air deflector 40 from coming off the second housing 31 during rotation and improving the operational reliability of the drive assembly 30.

[0132] 16 , in one embodiment of the present disclosure, the position limiting rod 317 includes an oil reservoir 3171 (e.g., an oil reservoir groove) and a position limiting rod body 3173, where the oil reservoir 3171 is recessed into the position limiting rod 317 and is arranged to store lubricating oil. The oil reservoir 3171 is provided on at least one of a side of the position limiting rod body 3173 that is close to the first transmission member 32 or a side that is away from the first transmission member 32. The oil reservoirs 3171 are arranged at intervals along the longitudinal direction of the position limiting rod 317.

[0133] In one embodiment of the present disclosure, the groove depth of the oil reservoir 3171 ranges from 0.1 to 0.8 mm. This reduces the contact area between the second transmission member 33 and the position limiting rod 317, reducing the frictional resistance generated when the second transmission member 33 slides relative to the position limiting rod 317 and improving the kinematic performance of the second transmission member 33. Furthermore, during long-term operation of the entire drive assembly 30, the lubricating oil applied to the contact surface between the position limiting rod 317 and the second transmission member 33 and used for friction is gradually consumed, and the lubricating oil in the oil reservoir 3171 gradually seeps out and is applied between the friction surfaces of the position limiting rod 317 and the second transmission member 33 as the components of the drive assembly 30 reciprocate, thereby improving the operational reliability of the drive assembly 30. During the reciprocating movement of the second transmission member 33, the seeped lubricating oil is collected in the oil reservoir 3171, reducing the loss of lubricating oil.

[0134] The position limiting rod 317 further includes a protrusion 3172, which is provided on both longitudinal ends of the position limiting rod body 3173 and adjacent to the oil reservoir 3171. In one embodiment of the present disclosure, the protrusion 3172 is provided on at least one of both longitudinal ends of the position limiting rod 317, thereby ensuring the lubricating oil storage function of the oil reservoir 3171 located at the end of the second transmission member 33.

[0135] As shown in FIG. 22 , in one embodiment of the present disclosure, the indoor unit 10 further includes a microswitch 14, which is provided in the second housing 31, and senses the timing state of the first transmission member 32 returning to the neutral position, and obtains the neutral position at which the air deflector 40 is stored into the shutdown state.

[0136] The microswitch 14 and the driving member 36 are electrically connected. The first transmission member 32 further includes a first blending unit 327 provided on the first sub-transmission member 322, and the first blending unit 327 controls the start and stop of the driving member 36 by selectively contacting the microswitch 14. For example, when the first blending unit 327 comes into contact with the microswitch 14 in conjunction with the rotation of the first transmission member 32, the operation of the driving member 36 stops, and when the first blending unit 327 disengages from the microswitch 14 in conjunction with the rotation of the first transmission member 32, the operation of the driving member 36 starts.

[0137] When the air conditioner 1 is in a shutdown state, the drive member body 361 rotates clockwise in conjunction with the drive member 36, and the first transmission member 32 rotates counterclockwise in conjunction with the drive member body 361. The control device records the number of step pulses applied to the drive member 36 as Q + Q × 10% steps. When the drive assembly 30 reaches the Q step position, the drive motor 362 continues to stall for Q × 10% steps. In this case, the microswitch 14 eliminates the motion error of the drive assembly 30, the step step-out error of the drive member, and motion errors caused by other uncontrollable external factors, ensuring accurate operation of the mechanism. When the shutdown procedure is initiated, the drive member body 361 rotates in the opposite direction in conjunction with the drive member 36. When the first transmission member 32 returns to its neutral position, the first blending section 327 contacts the contact of the microswitch 14. The control device stops supplying pulses to the drive member, and the system detects a shutdown state.

[0138] Motor stall refers to a state in which the motor outputs torque even at 0 rpm.

[0139] When the air conditioner 1 operates in heating mode, the first transmission member 32 rotates counterclockwise in conjunction with the drive member 36, and the second transmission member 33 is driven by the third transmission member 37 to move to the second attachment part 44, and the engagement between the second attachment part 44 and the third attachment part 315 locks the second attachment part 44 and releases the first attachment part 43, pushing the air deflector 40 to rotate upward. In this case, the air conditioner 1 starts blowing air, and the air deflector 40 guides the air downwards.

[0140] When the air conditioner 1 operates in cooling mode, the first transmission member 32 rotates clockwise in conjunction with the drive member 36, and the second transmission member 33 is moved to the first engagement part 43 by the drive of the third transmission member 37, and the engagement between the first engagement part 43 and the fourth engagement part 332 locks the first engagement part 43 and releases the second engagement part 44, pushing the air deflector 40 to rotate downward. In this case, the air conditioner 1 starts blowing air, and the air deflector 40 guides the air upward.

[0141] When the air conditioner 1 is operating in oscillating airflow mode, if the heating mode is determined, the air deflector 40 is controlled to reach the limit position and then blow air normally. If it is determined that the user desires oscillating airflow from the air deflector 40, the drive motor 362 rotates counterclockwise by Q steps, causing the air deflector 40 to rotate counterclockwise by Q steps until it reaches a predetermined position, at which point operation stops. The drive motor 362 then rotates clockwise, moving the air deflector 40 clockwise by Q steps and returning it to the heating limit position. This process is repeated for 15 minutes, after which the limit position return procedure begins. After the air deflector 40 reaches the predetermined position, the drive motor 362 rotates forward, causing the air deflector 40 to move clockwise by Q steps, returning it to the heating dead point, and continuing stall operation for Q × 10% steps to ensure a reliable return to the origin.

[0142] Those skilled in the art should understand that the scope of the present disclosure is not limited to the specific examples described above, and that specific elements of the examples can be modified and substituted without departing from the spirit of the present application. The scope of the present application is limited by the appended claims.
