[0040] As shown in Figure 1, an 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, which can be provided in either the indoor unit 10A or the outdoor unit 20A, is configured to expand a high-pressure liquid refrigerant into a low-pressure gas-liquid two-phase refrigerant.
[0041] The compressor is configured to compress a low-temperature, low-pressure gas-phase refrigerant and discharge the compressed high-temperature, high-pressure gas-phase refrigerant, and the high-temperature, high-pressure gas-phase refrigerant flows into the condenser.
[0042] The indoor heat exchanger exchanges heat between indoor air and the refrigerant transported through the indoor heat exchanger to liquefy or vaporize the refrigerant. The outdoor heat exchanger is configured to exchange heat between outdoor air and the refrigerant transported through the outdoor heat exchanger to liquefy or vaporize the refrigerant.
[0043] The outdoor fan is configured to promote heat exchange between the refrigerant flowing in the heat transfer tubes of the outdoor heat exchanger and the outdoor air, and the indoor fan is configured to promote heat exchange between the refrigerant flowing in the heat transfer tubes of the indoor heat exchanger and the indoor air to assist in temperature regulation.
[0044] The refrigerant cycle of the air conditioner 1 is performed by a compressor, a condenser (an indoor heat exchanger or an outdoor heat exchanger), an expansion valve (an indoor expansion valve and an outdoor expansion valve), and an evaporator (an outdoor heat exchanger or an indoor heat exchanger). The refrigerant cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and circulates the refrigerant to the conditioned side.
[0045] As shown in FIG. 2 , in some embodiments, the indoor unit 10A may be a wall-mounted indoor unit.
[0046] 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. The side plate 1012A is located on a side of the first housing 101A away from the wall.
[0047] The first housing 101A further includes a heat exchange air outlet 1013A and a heat exchange air inlet 1014A, each extending along the length of the indoor unit 10A. The heat exchange air outlet 1013A can be provided on a side panel 1012A of the first housing 101A, while the heat exchange air inlet 1014A can be provided on a top panel 1011A of the first housing 101A.
[0048] The indoor unit 10A further includes a base 102A and a heat exchange duct 103A, each of which is disposed within the first housing 101A. The heat exchange duct 103A communicates with a heat exchange air inlet 1014A and a heat exchange air outlet 1013A of the first housing 101A. Indoor air enters the first housing 101A through the heat exchange air inlet 1014A, passes through the heat exchange duct 103A, and is then blown out through the heat exchange air outlet 1013A.
[0049] In some embodiments, the indoor heat exchanger of the indoor unit 10A is arranged in the heat exchange air duct 103A, for example, it is arranged on the side of the heat exchange air duct 103A close to the heat exchange air inlet 1014A, and the indoor air is blown out from the heat exchange air outlet 1013A after heat exchange by the indoor heat exchanger.
[0050] In some embodiments, the indoor unit 10 further includes a drain pan. This drain pan can be located below the indoor heat exchanger and is configured to collect condensed water generated during heat exchange between the indoor air and the indoor heat exchanger. The drain pan can be connected to a drain pipe extending outside the first housing 101A to drain the condensed water outside the indoor unit 10A. In some embodiments, the drain pan can be integrally formed with the base 102A to reduce costs and improve installation efficiency.
[0051] The indoor fan of indoor unit 10A can be installed in the heat exchange duct. Under the forced convection of the indoor fan, indoor unit 10A draws indoor air from heat exchange inlet 1014A into heat exchange duct 103A. After heat exchange in the indoor heat exchanger, the indoor air forms a heat exchange airflow, which is then driven by the indoor fan and output through heat exchange outlet 1013A. In this way, the operation of the indoor heat exchanger and indoor fan can cool or heat the indoor air, bringing the indoor temperature to a comfortable level for the user.
[0052] The indoor unit 10A further includes a drive assembly 30A and an air deflector 40A. The drive assembly 30A is disposed within the first housing 101A. The air deflector 40A is disposed at the heat exchange air outlet 1013A and includes at least one rotating shaft disposed at each end of the air deflector 40A. The air deflector 40A can rotate about the rotating shaft to open or close the heat exchange air outlet 1013A.
[0053] In the related art, the air guide plate is restricted by the driving component, for example, by the driving part in the driving component, and usually can only perform a single rotation, for example, it can only rotate upward or downward, resulting in a smaller air outlet range and angle of the heat exchange outlet and poor air outlet effect.
[0054] In some embodiments, by increasing the width of the air deflector, the overall area of the air deflector is increased, thereby increasing the area of the heat exchange outlet corresponding to the air deflector, and the air discharge range of the heat exchange outlet is increased. However, to drive the air deflector, a more functional drive assembly is required. This drive assembly is large in size, complex in structure, high in cost, difficult to install, and has low reliability.
[0055] To solve the above problems, some embodiments of the present disclosure provide an air conditioner 1, in which the air guide plate of the air conditioner 1 has a large overall area and can be flipped up and down, and the load capacity of the driving component is high, to prevent the safety problem of the air guide plate falling due to insufficient torque when the driving component runs to the upper and lower limit positions of the air guide plate in the open state.
[0056] As shown in FIG. 3 , the air conditioner 1 includes an indoor unit 10 , and the indoor unit 10 includes a heat exchange air outlet 1013 , a heat exchange air inlet 1014 and an air guide plate 40 .
[0057] In some embodiments of the present disclosure, the indoor unit 10 includes a first shell 101 and a base 102 . The base 102 includes a bottom wall 1021 and two side walls 1022 arranged opposite to each other in the length direction (X direction in FIG. 3 ) of the bottom wall 1021 .
[0058] The indoor unit 10 further includes at least one drive assembly 30, which is disposed within the first housing 101. For example, the at least one drive assembly 30 is disposed 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 disposed on the two side walls 1022 of the base 102, respectively. In this case, the two drive assemblies 30 are symmetrically distributed, thereby more smoothly driving the air deflector 40 to open or close.
[0059] As shown in FIG. 4 , in some embodiments of the present disclosure, the driving assembly 30 includes a second housing 31 , which is disposed on a side wall 1022 of the base 102 .
[0060] In some embodiments of the present disclosure, the drive assembly 30 further includes a first transmission member 32 and a second transmission member 33. The first transmission member 32 is rotatably connected to the second housing 31. The second transmission member 33 is in transmission connection with the first transmission member 32, and the rotation of the first transmission member 32 can drive the second transmission member 33 to slide relative to the second housing 31.
[0061] As shown in FIG. 5 , in some embodiments of the present disclosure, the second housing 31 includes a first transmission portion 311 (eg, a sliding groove).
[0062] The drive assembly 30 further 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 air deflector 40 in the width direction (V direction in Figure 3).
[0063] In some embodiments of the present disclosure, the first transmission rod 34 includes a first shaft 341 (as 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 respectively disposed 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 coincide with each other. The first transmission rod 34 is slidably connected to the first transmission portion 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.
[0064] One end of the second transmission rod 35 is fixedly connected to the first transmission member 32, and the other end is slidably connected to the first transmission rod 34. In some embodiments of the present disclosure, the second transmission rod 35 includes a second transmission portion 351 (e.g., a slide groove). The second transmission portion 351 is disposed on the 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 portion 351 of the second transmission rod 35.
[0065] As shown in Figures 6 and 7, in some embodiments of the present disclosure, the second housing 31 includes a first sub-housing 11 and a second sub-housing 12, wherein the first sub-housing 11 is connected to the second sub-housing 12. A first transmission member 32 is movably connected to the first sub-housing 11 and can rotate relative to the first sub-housing 11. The first transmission portion 311 is disposed on the second sub-housing 12.
[0066] As shown in Figure 6, when the first transmission member 32 drives the second transmission rod 35 to rotate, the first shaft 341 of the first transmission rod 34 slides in the first transmission part 311 of the second shell 31, and the second shaft 342 slides in the second transmission part 351 of the second transmission rod 35. In this way, under the action of the second transmission rod 35, the air guide plate 40 is pushed to rotate.
[0067] As shown in Figures 7 and 8, the air deflector 40 includes a first rotating shaft 41 and a second rotating shaft 42, which are respectively disposed at opposite ends of the air deflector 40 in the width direction and are configured to cooperate and engage with the second transmission member 33 and the air deflector 40. In some embodiments of the present disclosure, at least one of the first rotating shaft 41 or the second rotating shaft 42 cooperates and engages with the second transmission member 33 and the air deflector 40. It is understood that when the first transmission member 32 drives the second transmission rod 35 to rotate, the second transmission member 33 can engage with the rotating shaft (the first rotating shaft 41 or the second rotating shaft 42) at one end of the air deflector 40, thereby enabling the other end of the air deflector 40, where the rotating shaft (the second rotating shaft 42 or the first rotating shaft 41) is not engaged with the second transmission member 33, to flip toward or away from the top plate 1011 of the first housing 101.
[0068] As shown in FIG9 , in some embodiments of the present disclosure, when the air conditioner 1 is operating in heating mode, hot air discharged through the heat exchange outlet 1013 of the indoor unit 10 moves upward. At this time, the drive assembly 30 drives the first transmission member 32 to rotate counterclockwise. Driven by the first transmission member 32, the second transmission member 33 moves toward one end of the air guide plate 40, causing the second transmission member 33 to engage with the first rotating shaft 41 or the second rotating shaft 42 of the air guide plate 40. For example, the second transmission member 33 engages with the first rotating shaft 41. At this time, the air guide plate 40 can rotate about the first rotating shaft 41, and the second rotating shaft 42 is free. Thus, through the interaction between the first transmission member 32, the first transmission rod 34, the second transmission rod 35, and the air guide plate 40, the air guide plate 40 is pushed to rotate clockwise about the first rotating shaft 41 toward the top plate 1011 of the first housing 101. At this time, the air blown out of the heat exchange outlet 1013 of the indoor unit 10 is directed by the air guide plate 40 toward the bottom of the indoor unit 10.
[0069] As shown in Figure 10, in some embodiments of the present disclosure, when the air conditioner 1 is operating in the cooling mode, the cold air discharged through the heat exchange outlet 1013 of the indoor unit 10 moves downward. At this time, the driving assembly 30 drives the first transmission member 32 to rotate clockwise, and the second transmission member 33 moves toward the other end of the air guide plate 40 under the drive of the first transmission member 32, so that the second transmission member 33 is engaged with the first rotating shaft 41 or the second rotating shaft 42 of the air guide plate 40. For example, the second transmission member 33 is engaged with the second rotating shaft 42. At this time, the air guide plate 40 can rotate around the second rotating shaft 42, and the first rotating shaft 41 is in a free state. In this way, through the mutual cooperation between the first transmission member 32, the first transmission rod 34, the second transmission rod 35 and the air guide plate 40, the air guide plate 40 is pushed around the second rotating shaft 42 and flipped counterclockwise away from the top plate 1011 of the first shell 101. At this time, the wind blown out from the heat exchange outlet 1013 of the indoor unit 10 will be guided by the air guide plate 40 to the top of the indoor unit 10.
[0070] It should be noted that there is no correspondence between the direction in which the drive assembly 30 drives the first transmission member 32 to rotate and the direction in which the air guide plate 40 flips around the end at which it is engaged with the second transmission member 33. For example, when the air conditioner 1 is operating in heating mode, the drive assembly 30 can be configured to drive the first transmission member 32 to rotate clockwise, thereby causing the air guide plate 40 to flip clockwise around the end at which it is engaged with the second transmission member 33 toward the top plate 1011 of the first housing 101, thereby causing the air blown out of the heat exchange outlet 1013 of the indoor unit 10 to be directed downward by the air guide plate 40.
[0071] Similarly, when the air conditioner 1 is operating in cooling mode, the driving component 30 can be set to drive the first transmission member 32 to rotate counterclockwise, so that the air guide plate 40 can be flipped counterclockwise around the end at which it is engaged with the second transmission member 33, away from the top plate 1011 of the first shell 101, thereby achieving the air blown out from the heat exchange outlet 1013 of the indoor unit 10 will be guided by the air guide plate 40 to the top of the indoor unit 10.
[0072] It is understood that when the at least one drive assembly 30 includes two or more drive assemblies 30, when the air conditioner 1 operates in the same mode, the rotation directions of the first transmission members 32 of different drive assemblies 30 can be opposite. In this way, the drive assembly 30 can drive the air deflector 40 to achieve upside-down movement, meeting the user's requirements for the air outlet direction of the indoor unit 10 in the same mode. For example, as shown in FIG9 , when the air conditioner 1 operates in cooling mode, the user can also control the air deflector 40 to flip upward.
[0073] In some embodiments of the present disclosure, simulation analysis is performed by setting the shape of the curve of the first transmission portion 311 to determine the motion trajectory of the air deflector 40. Variations in the curvature of the first transmission portion 311 can change the opening and closing angular velocity of the air deflector 40 at each moment.
[0074] It is understandable that, when the opening and closing angular velocity of the air guide plate 40 at each moment is determined, the shape of the curve of the first transmission part 311 and the curvature of each location on the first transmission part 311 can be reversely deduced through logical relationship operations.
[0075] As shown in FIG5 , in some embodiments of the present disclosure, the rotation axis of the first transmission member 32 is defined as point A, the position where the common axis of the first axis 341 and the second axis 342 of the first transmission rod 34 is located is defined as point B, and the linear velocity of point B on the second transmission rod 35 is V1. The first position in the middle of the air deflector 40 is positioned as point C, and the axis of the rotating shaft at one end of the air deflector 40 is defined as point D. For example, the axis of the first rotating shaft 41 of the air deflector 40 is defined as point D. The linear velocity of the first position point C in the middle of the air deflector 40 is V2, and the distance between the axis point D of the first rotating shaft 41 and the first position point C of the air deflector 40 is R DC , linear velocity V2 is perpendicular to R DC ; Define the intersection of the extended lines of line segment AB and line segment CD as point O.
[0076] The distance between point A and point O is L OA ; The distance between point C and point O is L OC ; The distance between point A and point B is R AB ; The distance between point B and point O is L OB The angular velocity of the wind deflector 40 around the first rotation axis 41 is ω DC ; The distance between point B and point C is L BC ; The angular velocity of the first transmission member 32 rotating around the rotation axis is ω1.
[0077] In some embodiments of the present disclosure, DC 、L BC , ω1 and R DC Make preset values and combine them with the measured L OA and L OC The values of the first rotation axis 41 are logically calculated to determine the R when the air guide plate 40 rotates to different positions around the first rotation axis 41. AB Since point A is known and determined, when the wind deflector 40 rotates to different positions, R AB After the value of is determined, multiple positions of point B can be obtained. By connecting the multiple positions that point B passes through, the shape of the curve of the first transmission part 311 and the curvature of each position on the first transmission part 311 can be obtained.
[0078] For example, when the air guide plate 40 rotates, the first transmission member 32 rotates at a constant speed at a preset angular velocity ω1. The angular velocity ω of the air guide plate 40 when it rotates to different positions is DC Therefore, when the air guide plate 40 rotates to any position, the corresponding position of the second transmission member 33 is predictable. By measuring the L corresponding to the air guide plate 40 rotating to different positions OA and L OC The value of ω corresponding to the wind deflector 40 when it is rotated to different positions DC、L BC ,ω1,R DC 、L OA and L OC The value of is brought into the logical relationship, and the corresponding R when the air guide plate 40 rotates to different positions is determined by logical relationship operation. AB The value of , and then obtain multiple positions of point B, and determine the shape of the curve of the first transmission part 311 and the curvature of each point on the first transmission part 311 according to the multiple positions of point B. Among them, 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 .
[0079] The first transmission member 32 drives the second transmission rod 35 to push the end of the first transmission rod 34 provided with the first shaft 341 and the second shaft 342, so that it moves within the restriction of the first transmission part 311. Since the angular velocity of the first transmission member 32 in the uniform rotational motion is ω1, the curvature of the curve of the first transmission part 311 at each moment during the motion process of point B is a change amount, so R AB The magnitude of is the amount of change over time. Reflected in the transmission of the motion speed of the drive assembly 30, the instantaneous angular velocity ω of the air guide plate 40 at any time can be limited. DC , and then the curvature of the curve of the first transmission part 311 can be inferred, which is conducive to designing a technical solution for the product structure based on the parameter requirements of the customer end of the product.
[0080] As shown in FIG8 , when the air guide plate 40 closes the heat exchange outlet 1013, the length direction of the first transmission rod 34 is perpendicular to the air guide plate 40, that is, the line segment AB and the perpendicular line of the linear velocity V2 are on the same straight line. DC 、L BC , ω1 and R DC The value of determines the position of the rotation axis point A of the first transmission member 32 in the length direction of the first transmission rod 34.
[0081] As shown in Figures 22 and 24, in some embodiments of the present disclosure, the drive assembly 30 further includes a drive member 36, which is disposed within 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 in transmission connection with the first transmission member 32. The drive motor 362 includes an output shaft 3621, and the drive motor 362 is fixedly connected to the drive member body 361 via the output shaft 3621.
[0082] In some embodiments of the present disclosure, the driver body 361 includes a receiving portion 3611 configured to connect to the output shaft 3621 of the drive motor 362. The receiving portion 3611 is, for example, a groove disposed at the rotation axis of the driver body 361. The driver body 361 and the first transmission member 32 are each a gear.
[0083] In some embodiments of the present disclosure, the output shaft 3621 of the drive motor 362 rotates, driving the driver body 361 to rotate about its rotation axis. The rotation of the driver body 361 drives the first transmission member 32 to rotate about its rotation axis, thereby driving the second transmission rod 35 to rotate synchronously. The second transmission rod 35 pushes the second shaft 342 of the first transmission rod 34 to slide within the second transmission portion 351, and the first shaft 341 slides within the first transmission portion 311. The end of the first transmission rod 34 connected to the air deflector 40 pushes the air deflector 40 to rotate. The air deflector 40 rotates clockwise or counterclockwise about its rotation axis connected to the first transmission rod 34, thereby enabling the air deflector 40 to open upward or downward to blow air.
[0084] As shown in FIG. 24 , in some embodiments of the present disclosure, the air conditioner 1 further includes a torque sensor and a controller. The torque sensor is configured to detect the torque of the output shaft 3621 of the drive motor 362 .
[0085] When the air conditioner 1 is operating stably, the power of the drive motor 362 is fixed, and the torque sensor determines whether the torque of the drive motor 362 is less than or equal to a preset threshold. Here, the preset threshold is the threshold for normal operation of the drive motor 362, and the preset threshold is less than the rated torque of the drive motor 362. In some embodiments 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 avoid damage to the drive motor 362 due to excessive torque.
[0086] When the torque of the output shaft 3621 is greater than a preset threshold, that is, when the output shaft 3621 encounters a large resistance when driving the first transmission member 32, it indicates that the curvature of the curve at the first transmission part 311 corresponding to the first shaft 341 changes sharply. At this time, the position in the first transmission part 311 of the second shell 31 corresponding to the axis center of the first shaft 341 of the first transmission rod 34 (that is, point B in Figure 8) is moved a preset distance toward the direction close to the rotation axis center of the first transmission member 32.
[0087] The above process is repeated to continue detecting the torque of the output shaft 3621 corresponding to each position of the first shaft 341 in the first transmission part 311 through the torque sensor until the detection is completed.
[0088] The transmission connection relationship between the first transmission member 32 and the driving member body 361 is unchanged, but the curvature of the first transmission part 311 of the second shell 31 is changed, so the driving force required when the first axis 341 of the first transmission rod 34 slides in the first transmission part 311 is changed.
[0089] In some embodiments of the present disclosure, as shown in FIG8 , in the process of moving point B toward the direction of the rotation axis of the first transmission member 32 by a preset distance, the position of the adjacent point B on the curve of the first transmission part 311 can be moved toward the direction of point A, and the moving distance can be less than the preset distance, so that the curvature of the curve on the curve of the first transmission part 311 can be smoothly transitioned. Moving point B toward point A by a preset distance can reduce R AB The value of R AB The lever arm is reduced. According to the lever principle, R AB The lever arm is reduced, so that the driving force of the second transmission rod 35 on the axis center (i.e., point B) of the first axis 341 of the first transmission rod 34 increases, thereby increasing the driving force of the first transmission rod 34 on the air guide plate 40, improving the load-bearing capacity of the drive component 30, and further improving the reliability of the rotation of the air guide plate 40.
[0090] The end of the second transmission part 351 away from the rotation axis of the first transmission member 32 (i.e., point A) is defined as point L. The distance between point L and point A is L. LA In some embodiments of the present disclosure, L LA The value of L is N times the length of the second transmission part 351. For example, LA The value is twice the length of the second transmission part 351, so that the reliability of the driving assembly 30 can be increased.
[0091] In some embodiments of the present disclosure, when the distance R AB Meet L LA =Z×R AB When, that is, when L LA The value is equal to Z times R AB When the value of , when the first transmission rod 34 rotates at the same angle, the driving force exerted by the second transmission rod 35 on the axis of the first shaft 341 will increase by Z times. Therefore, by moving point B towards point A by a preset distance, R can be shortened. AB The length of the second transmission rod 35 increases the driving force of the first shaft 341 of the first transmission rod 34, making the operation of the driving assembly 30 more reliable and more stable.
[0092] In some embodiments of the present disclosure, in order to ensure that the curvature of the curve of the first transmission part 311 meets the reliability of operation when the driving assembly 30 drives the first transmission member 32 to rotate, the size and shape of the curvature of the curve of the first transmission part 311 are detected and adjusted.
[0093] As shown in Figures 8 and 9, the first transmission portion 311 of the second housing 31 includes multiple, sequentially connected arcuate grooves, with the ends of at least two of the multiple arcuate grooves tangentially connected. This reduces the resistance of the first transmission portion 311 to the first shaft 341 of the first transmission rod 34, thereby improving the smoothness of the operation of the drive assembly 30.
[0094] The arc-shaped endpoints of the first transmission portion 311 are points H and G, respectively. In the first transmission portion 311, the connection points of the multiple arc grooves extending from point H to point G are defined as points I, J, K, E, and F, respectively. The first transmission portion 311 includes arcs HI, IJ, JE, EF, and FG, which are connected in sequence. Arc JE is located in the middle of the first transmission portion 311, with point K being the midpoint of arc JE. Therefore, point K is the point on the first transmission portion 311 farthest from the rotation axis of the first transmission member 32.
[0095] In some embodiments of the present disclosure, the first transmission part 311 can satisfy at least one of the conditions that arc HI is a perfect circle, arc JE is a perfect circle, or arc FG is a perfect circle. This can reduce the influence of the curvature of the curve of the first transmission part 311 on the torque of the output shaft 3621 of the drive motor 362, and increase the smoothness of the operation of the drive component 30.
[0096] In some embodiments of the present disclosure, the length of the line segment between the arc HI and the rotation axis A of the first transmission member 32 is defined as R HA The length of the line segment between arc JE and point A is defined as R JA , the length of the line segment between arc FG and point A is defined as R FA , and R HA 、R FA and R JA Satisfy R HA =R FA <R JA In this way, when the first shaft 341 rotates from point K to the two ends of the first transmission part 311, while the driving force of the driving motor 362 remains unchanged, the driving force of the second transmission rod 35 on the first transmission rod 34 increases, ensuring the reliable operation of the driving component 30.
[0097] As shown in Figure 10, line segments AH and AI form an angle ∠HAI, line segments AJ and AE form an angle ∠JAE, and line segments AF and AG form an angle FAG. In some embodiments of the present disclosure, the configuration of the first transmission portion 311 satisfies at least one of 0°≤∠HAI≤25°, 10°≤∠JAE≤25°, or 0°≤∠FAG≤25°. This allows the first shaft 341 of the first transmission rod 34 to operate more reliably within the first transmission portion 311, avoiding any stuck points in the operation of the first shaft 341 within the first transmission portion 311.
[0098] In some embodiments of the present disclosure, when the first shaft 341 is disposed within the arc JE, a first gap (e.g., a first bilateral gap) exists between the first shaft 341 and the width of the arc JE. Specifically, the gap between the two sides of the first shaft 341 in the width direction of the arc JE and the width of the arc JE is the first gap, which can be, for example, 0.2 mm. This prevents the first shaft 341 from sliding within the arc JE, thereby improving the smoothness of the operation of the drive assembly 30.
[0099] When the first shaft 341 is fitted within the arc HJ, a second gap (e.g., a second bilateral gap) exists between the first shaft 341 and the width of the arc HJ. That is, the gap between the two sides of the first shaft 341 in the width direction of the arc HJ and the width of the arc HJ is the second gap. In some embodiments of the present disclosure, the second gap is smaller than the first gap, and the second gap is, for example, 0.1 mm. This prevents the first shaft 341 from sliding within the arc HJ, thereby improving the smoothness of the operation of the drive assembly 30.
[0100] When the first shaft 341 is fitted within the arc EG, a third gap (e.g., a third bilateral gap) exists between the first shaft 341 and the width of the arc EG. That is, the third gap is the gap between the two sides of the first shaft 341 in the width direction of the arc EG and the width of the arc EG. In some embodiments of the present disclosure, the third gap is smaller than the first gap, and the third gap is, for example, 0.1 mm. This prevents the first shaft 341 from sliding within the arc EG, thereby improving the smoothness of the operation of the drive assembly 30.
[0101] It can be understood that since the driving force required for the first shaft 341 is the largest at point K, by making the first gap larger than any one of the second gap and the third gap, the first shaft 341 can be prevented from getting stuck in the arc JE.
[0102] In some embodiments of the present disclosure, as shown in Figures 8 and 9, line segment AK and line segment AH define ∠KAH, and ∠KAH is, for example, 120°. When the first shaft 341 runs from point K to point H along the first transmission part 311, the air guide plate 40 runs from a closed state to an open state with a downward opening. At this time, the maximum rotation angle of the air guide plate 40 is, for example, 75°.
[0103] In some embodiments of the present disclosure, as shown in Figure 9, line segment AG and line segment AK define ∠KAG. For example, ∠KAG can be 150°. When the first axis 341 runs from point K to point G along the first transmission part 311, the air guide plate 40 runs from a closed state to an open state opening upward. At this time, the maximum rotation angle of the air guide plate 40 is, for example, 80°.
[0104] It should be noted that the maximum rotation angle of the upward opening of the air guide plate 40 is greater than the maximum rotation angle of the downward opening of the air guide plate 40. In this way, the blowing range of the cold air when the air guide plate 40 is opened upward can be increased, avoiding blowing the cold air onto the ceiling of the indoor room, avoiding blocking the air outlet, and affecting the air outlet efficiency.
[0105] It can be understood that since the indoor unit 10 is usually located at the top of the indoor space, when the air guide plate 40 opens downward, the downward air outlet of the indoor unit 10 will not be blocked, so the downward opening angle of the air guide plate 40 can be smaller than the upward opening angle of the air guide plate 40.
[0106] As shown in FIG11 , in some embodiments 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 disposed at both ends of the second housing 31 in a lengthwise direction parallel to the second transmission member 33. The first rotating portion 312 cooperates with the first rotating shaft 41 of the air deflector 40, and the second rotating portion 313 cooperates with the second rotating shaft 42 of the air deflector 40.
[0107] In some embodiments of the present disclosure, at least a portion of the first rotating portion 312 and the second rotating portion 313 is open, so that jamming of the drive component 30 during operation due to thermal expansion and contraction of the drive component 30 material can be avoided during the rotation of the air guide plate 40.
[0108] In some embodiments of the present disclosure, the air deflector 40 further includes a first engaging portion 43 and a second engaging portion 44. The first rotating shaft 41 is disposed on the first engaging portion 43, and the second rotating shaft 42 is disposed on the second engaging portion 44. The first engaging portion 43 engages with the second transmission member 33 to engage within the first rotating portion 312; the second engaging portion 44 engages with the second transmission member 33 to engage within the second rotating portion 313. Thus, the air deflector 40 is tilted downward by engaging the first engaging portion 43 with the first rotating portion 312, and tilted upward by engaging the second engaging portion 44 with the second rotating portion 313.
[0109] When the first engaging portion 43 is engaged with the first rotating portion 312, the air deflector 40 rotates about the first rotating shaft 41 on the first engaging portion 43. At this time, the air deflector 40 can swing relative to the heat exchange outlet 1013 through the cooperation between the first engaging portion 43 and the first rotating portion 312. Thus, when the air conditioner 1 is operating in cooling mode, the air deflector 40 can flip downward, that is, the air outlet area formed between the air deflector 40 and the heat exchange outlet 1013 faces upward (as shown in FIG. 10 ), thereby achieving an upward blowing design of the air conditioner 1.
[0110] When the second engaging portion 44 is engaged with the second rotating portion 313, the air deflector 40 rotates about the second rotating shaft 42 on the second engaging portion 44. At this time, the air deflector 40 can swing relative to the heat exchange outlet 1013 through the engagement between the second engaging portion 44 and the second rotating portion 313. Thus, when the air conditioner 1 is operating in heating mode, the air deflector 40 can flip upward, i.e., the air outlet area formed between the air deflector 40 and the heat exchange outlet 1013 is downwardly disposed (as shown in FIG. 9 ), thereby achieving a downward blowing design of the air conditioner 1.
[0111] As shown in Figures 18 and 23, in some embodiments of the present disclosure, the air deflector 40 further includes a first hooking portion 45 (e.g., a hook claw). The first hooking portion 45 is provided on at least one of the first clamping portion 43 and the second clamping portion 44. When the air deflector 40 includes two first hooking portions 45, the two first hooking portions 45 are connected to the first rotating shaft 41 and the second rotating shaft 42, respectively.
[0112] The second housing 31 also includes a second hooking portion 316 (e.g., a hook claw). The second hooking portion 316 is disposed within at least one of the first rotating portion 312 and the second rotating portion 313. The first hooking portion 45 and the second hooking portion 316 selectively abut against each other. That is, when the first hooking portion 45 of the air deflector 40 rotates above the second hooking portion 316, the first hooking portion 45 abuts against the second hooking portion 316. In some embodiments of the present disclosure, the second hooking portion 316 is disposed corresponding to the first hooking portion 45. If the second housing 31 includes two second hooking portions 316, the two second hooking portions 316 are disposed on one side of the first rotating portion 312 and the second rotating portion 313, respectively, adjacent to each other. For example, the second hooking portion 316 within the first rotating portion 312 is disposed on a side of the first rotating portion 312 adjacent to the second rotating portion 313, while the second hooking portion 46 within the second rotating portion 313 is disposed on a side of the second rotating portion 313 adjacent to the first rotating portion 312.
[0113] In some embodiments of the present disclosure, the side where the first hook portion 45 is connected to the corresponding rotating shaft (such as the first rotating shaft 41 or the second rotating shaft 42) is the long side, and the side away from the corresponding rotating shaft is the short side or the vertex. In this way, the structural strength of the first hook portion 45 can be improved, and the first hook portion 45 can be more conveniently abutted against the second hook portion 316, so that the structural stability of the first hook portion 45 after abutting against the second hook portion 316 is better.
[0114] In this way, by providing a first hooking portion 45 in at least one of the first clamping portion 43 and the second clamping portion 44, and providing a second hooking portion 316 in at least one of the first rotating portion 312 and the second rotating portion 313, when the first clamping portion 43 and the first rotating portion 312 abut against each other to limit the fit, or when the second clamping portion 44 and the second rotating portion 313 abut against each other to limit the fit, the air guide plate 40 can move to the limit point, that is, at this time the angle between the air guide plate 40 and the second transmission member 33 is the largest, thus realizing the angle limit of the opening of the air guide plate 40 and facilitating the reciprocating motion of the air guide plate 40, thereby increasing the air outlet range and angle of the indoor unit 10.
[0115] As shown in Figures 17 and 18, in some embodiments of the present disclosure, the second housing 31 further includes a guide surface 314. The guide surface 314 is disposed within at least one of the first rotating portion 312 and the second rotating portion 313 and is configured to guide the air deflector 40 during rotation. The first hooking portion 45 rotates along the extension direction of the guide surface 314 until it abuts against the second hooking portion 316.
[0116] In some embodiments of the present disclosure, when the air deflector 40 rotates open from a closed state and the included angle between the air deflector 40 and the length direction of the second transmission member 33 reaches a first preset angle, the first hooking portion 45 abuts the second hooking portion 316, and the second hooking portion 316 begins to hook the first hooking portion 45 and begins to bear the force of the rotating shaft of the air deflector 40. The air deflector 40 continues to rotate, pushed by the first transmission rod 34, until it reaches the second preset angle.
[0117] During the period when the air deflector 40 rotates from the first preset angle to the second preset angle, the first hooking portion 45 and the second hooking portion 316 maintain abutting engagement.
[0118] When the air deflector 40 rotates to a second predetermined angle, the first hook portion 45 maintains contact with the second hook portion 316, and the second hook portion 316 absorbs the pressure generated by the rotation of the air deflector 40. The second hook portion 316 helps improve the reliability of the indoor unit. For example, if the second transmission member 33 breaks where it supports the air deflector 40, or if the second transmission member 33 is directly removed, the second hook portion 316 will still support the air deflector 40 due to its engagement with the first hook portion 45. This ensures a wide air outlet range for the indoor unit 10 while improving its reliability.
[0119] As shown in Figures 12, 13 and 23, in some embodiments of the present disclosure, the second transmission member 33 includes a blocking portion 331 (for example, a baffle), and the blocking portion 331 is arranged at both ends of the second transmission member 33 along the length direction. The blocking portion 331 is configured to close or semi-close the first rotating portion 312 or the second rotating portion 313, thereby limiting the first rotating shaft 41 in the first rotating portion 312, or limiting the second rotating shaft 42 in the second rotating portion 313, so that the first clamping portion 43 rotates around the first rotating shaft 41 in the first rotating portion 312 or the second clamping portion 44 rotates around the second rotating shaft 42 in the second rotating portion 313, thereby realizing the rotation of the air guide plate 40.
[0120] The blocking portion 331 is chamfered at one end away from the second transmission member 33, so that there is a contact slope between the blocking portion 331 and the first rotating shaft 41 or the second rotating shaft 42, ensuring that the second transmission member 33 can limit the first rotating shaft 41 or the second rotating shaft 42 more smoothly.
[0121] In this way, the blocking portion 331 and the second hooking portion 316 can reinforce each other, so that the second hooking portion 316 can share part of the pressure of the first hooking portion 45 on the second transmission member 33, thereby improving the reliability of the blocking portion 331 and the second hooking portion 316.
[0122] As shown in FIG. 24 , in some embodiments of the present disclosure, the drive assembly 30 further includes a third transmission member 37. The third transmission member 37 is disposed between the first transmission member 32 and the second transmission member 33 and is in transmission connection with the first transmission member 32 and the second transmission member 33, respectively. Rotation of the first transmission member 32 drives the third transmission member 37 to rotate, which in turn drives the second transmission member 33 toward one end in the width direction of the air deflector 40, ultimately engaging with a rotating shaft at one end of the air deflector 40.
[0123] As shown in FIG12 , the second transmission member 33 further includes a second tooth portion 333. The second tooth portion 333 serves as the transmission input structure of the second transmission member 33. The tooth tops of the standard teeth of the second tooth portion 333 are chamfered, that is, the right-angled corner portions of the standard tooth tops are chamfered to form arcuate surfaces. This prevents the tooth tops of the second tooth portion 333 from colliding with and damaging the third transmission member 37 during use, thereby improving the transmission stability of the second transmission member 33.
[0124] As shown in FIG. 19 , the third transmission member 37 is, for example, a sheave. The third transmission member 37 includes a first tooth portion 371 and a matching hole 372 . The matching hole 372 and the first tooth portion 371 are spaced apart. The first tooth portion 371 and the second tooth portion 333 are engaged with each other.
[0125] In some embodiments of the present disclosure, the rotational axis of the driver body 361 of the driver 36 is coaxially arranged with the rotational axis of the third transmission member 37. The driver body 361 and the third transmission member 37 are kinematically connected, and rotation of the driver body 361 does not directly drive rotation of the third transmission member 37. The coaxial and overlapping arrangement of the driver body 361 and the third transmission member 37 can reduce the space occupied by the drive assembly 30 within the second housing 31.
[0126] In other embodiments of the present disclosure, the rotation axis of the driving member body 361 may not be coaxially arranged with the rotation axis of the third transmission member 37. In this way, it is possible to avoid the limitation of the parameters of the gear transmission coordination between the first transmission member 32, the third transmission member 37 and the driving member body 361 due to the coaxial arrangement of the rotation axis of the driving member body 361 and the rotation axis of the third transmission member 37, so that the driving component 30 can adapt to various parameter requirements.
[0127] As shown in FIG12 , in some embodiments of the present disclosure, the second transmission member 33 further includes a fourth engaging portion 332, which is disposed at at least one of the two ends in the longitudinal direction of the second transmission member 33. As shown in FIG14 , in some embodiments of the present disclosure, the second housing 31 further includes at least one third engaging portion 315, which is disposed at at least one of the two ends of the second housing 31 in the longitudinal direction parallel to the second transmission member 33. The third engaging portion 315 and the fourth engaging portion 332 selectively engage with each other during the sliding process of the second transmission member 33. That is, after the third engaging portion 315 is inserted into the fourth engaging portion 332, the second transmission member 33 is fixed to the second housing 31 due to the engagement of the third engaging portion 315 and the fourth engaging portion 332, thereby fixing the relative position of the second transmission member 33 and the second housing 31. This allows the blocking portion 331 to always engage with the first rotating portion 312 or the second rotating portion 313. In this way, the connection between the second transmission member 33 and the second shell 31 can be achieved to fix the second transmission member 33, thereby strengthening the force strength of the blocking part 331 and the first rotating part 312 or the second rotating part 313 on the air guide plate 40.
[0128] In some embodiments of the present disclosure, the third engaging portion 315 may be a slot, and the fourth engaging portion 332 may be a hook. In other embodiments of the present disclosure, the third engaging portion 315 may be a hook, and the fourth engaging portion 332 may be a slot. Thus, the second transmission member 33 and the second housing 31 are secured together by the engagement between the hook and the slot.
[0129] As shown in Figures 17 and 20, in some embodiments of the present disclosure, the first transmission member 32 includes a connecting portion 321 (e.g., a mating post), which selectively engages with a mating hole 372 of the third transmission member 37. In this way, the connecting portion 321 rotates with the first transmission member 32 until it slides into the mating hole 372, thereby driving the third transmission member 37 to rotate.
[0130] In some embodiments 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. The first sub-transmission member 322 and the second sub-transmission member 323 are coaxially arranged and overlapped. The third tooth portion 324 is arranged around the first sub-transmission member 322, and the connecting portion 321 is arranged on the second sub-transmission member 25. In this way, the connecting portion 321 and the third tooth portion 324 can be located in different planes parallel to the second housing 31, thereby preventing interference between the connecting portion 21 and the third tooth portion 324.
[0131] For example, the first sub-transmission member 322 and the second sub-transmission member 323 are integrally formed, which can reduce costs and increase the reliability of the driving assembly.
[0132] The third transmission member 37 further includes at least one mating surface 373, which is recessed toward the axis of the third transmission member 37. The at least one mating surface 373 is disposed between the first tooth portion 371 and the mating hole 372. In some embodiments of the present disclosure, when the third transmission member 37 includes two mating surfaces 373, the two mating surfaces 373 are disposed on either side of the mating hole 372, respectively.
[0133] In some embodiments of the present disclosure, the first transmission member 32 further includes an engaging portion 325 (e.g., a protrusion) disposed 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 to restrict the rotation of the third transmission member 37. Simultaneously, as the first transmission member 32 continues to rotate clockwise or counterclockwise, the engaging portion 325 slides relative to the mating surface 373, and the third transmission member 37 no longer rotates with it, thereby limiting the position of the third transmission member 37.
[0134] In some embodiments of the present disclosure, when the connecting portion 321 slides in the mating hole 372 toward the direction of the rotation axis of the third transmission member 37, the angular velocity of the rotation of the third transmission member 37 increases; when the connecting portion 321 slides out of the mating hole 372 toward the direction of the rotation axis of the third transmission member 37, the angular velocity of the rotation of the third transmission member 37 decreases.
[0135] When the air deflector 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. Specifically, when the air deflector 40 begins to rotate from its closed position to open the heat exchange outlet 1013, the angular velocity of the third transmission member 37 reaches its maximum. In other words, when the first transmission member 32 rotates at a relatively small angle, the third transmission member 37 can rotate at a relatively large angle, allowing the engaging portion 325 to engage with the mating surface 373 of the third transmission member 37 to achieve self-locking. Furthermore, due to the relatively large rotation angle of the third transmission member 37, the second transmission member 33 travels a relatively large distance through transmission and sliding movement with the third transmission member 37. Specifically, after a relatively small rotation angle of the first transmission member 32, the second transmission member 33 can engage with the first rotating shaft 41 or the second rotating shaft 42 of the air deflector 40, thereby engaging the first engaging portion 43 or the second engaging portion 44 of the air deflector 40 with the first rotating portion 312 or the second rotating portion 313, respectively.
[0136] At this time, the stroke of the first transmission member 32 driving the first transmission rod 34 to run is relatively small, and the quick retreat and advance motion mechanism combined with the slow extension and contraction motion mechanism has great advantages in maintaining the clamping position of the first clamping part 43 or the second clamping part 44 of the air guide plate 40. The motion timing of the two motion mechanisms can be staggered, thereby ensuring that after the second transmission member 33 is clamped to the first clamping part 43 or the second clamping part 44, the air guide plate 40 rotates at a smaller angle, ensuring the reliability of the motion mechanism of the air guide plate 40, and avoiding the problem that the second transmission member 33 does not move to the clamping position and the air guide plate 40 rotates out of the first rotating part 312 or the second rotating part 313.
[0137] As shown in FIG. 24 , the driving member body 361 cooperates with the third tooth portion 324 on the first sub-transmission member 322 , thereby realizing the transmission connection between the driving member 36 and the first transmission member 32 .
[0138] In some embodiments of the present disclosure, since the second transmission member 33 is in transmission connection with the third transmission member 37, the second transmission member 33 also undergoes linear motion during the rotation of the third transmission member 37. When the first transmission member 32 continues to rotate until the engaging portion 325 engages with the mating surface 373 and locks the third transmission member 37, the second transmission member 33 is also limited and locked by the third transmission member 37. At this point, the air deflector 40 is in the open position, and the first hooking portion 45 on the first engaging portion 43 or the first hooking portion 45 on the second engaging portion 44 slides until it engages with the second hooking portion 46.
[0139] In this way, through the cooperation and limitation between the locking portion 325 and the mating surface 373, the second transmission member 33 can be prevented from moving in the sliding direction of the second transmission member 33, thereby preventing the first locking portion 43 of the second transmission member 33 from being disengaged from the locking connection with the first hooking portion 45, and the second locking portion 44 of the second transmission member 33 from being disengaged from the locking connection with the second hooking portion 46.
[0140] In addition, the engagement portion 325 on the first transmission member 32 cooperates with the mating surface 373 on the third transmission member 37 to limit the freedom of the second transmission member 33 in the sliding direction of the second transmission member 33. The second limiting portion 335 and the third limiting portion 336 also limit the freedom of the second transmission member 33 in the sliding direction of the second transmission member 33. In this way, the gap between the second tooth portion 333 and the first tooth portion 371 of the third transmission member 37 when the second tooth portion 333 of the second transmission member 33 and the first tooth portion 371 of the third transmission member 37 are generated when they are engaged, which can cause the second transmission member 33 to retract after reaching the target position and the problem of unreliable locking of the second transmission member 33.
[0141] As shown in FIG20 , in some embodiments of the present disclosure, the engaging portion 325 on the second sub-transmission member 323 of the first transmission member 32 includes a second mating portion 326 , which is, for example, a groove recessed toward the rotation axis of the first transmission member 32 . The connecting portion 321 is disposed within the second mating portion 326 .
[0142] As shown in Figure 21, the first transmission member 32 rotates to mate the connecting portion 321 with the mating hole 372. Thus, the rotation of the first transmission member 32 causes the connecting portion 321 to drive the third transmission member 37 to rotate. It should be noted that the connecting portion 321 first slides within the mating hole 372 toward the rotation axis of the third transmission member 37, and then slides out of the mating hole 372 away from the rotation axis of the third transmission member 37.
[0143] The point where the connecting part 321 rotates to the first contact with the third transmission member 37 is defined as the first matching point M, and the point where the connecting part 321 rotates to the point where it disengages from the third transmission member 37 is defined as the second matching point N. The rotation angle of the connecting part 321 sliding from point M to point N is defined as ∠MAN.
[0144] As shown in FIG10 , two ends of the first transmission part 311 are point H and point G respectively, and the angle at which the first shaft 341 runs from point H to point G is defined as ∠HAG.
[0145] In some embodiments of the present disclosure, ∠MAN and ∠HAG satisfy the following relationship: 8 ≤ ∠HAG / ∠MAN ≤ 12. This avoids situations where the connecting portion 321 of the first transmission member 32 slides too shallowly into the mating hole 372 of the third transmission member 37 due to a too small ∠MAN angle, or where the driving force and contact area of the first transmission member 32 on the third transmission member 37 are insufficient due to mold part clearance or product dimensional tolerances. This ensures that the sliding stroke of the connecting portion 321 of the first transmission member 32 after sliding into the mating hole 372 of the third transmission member 37 meets the driving force and contact area requirements of the first transmission member 32 on the third transmission member 37, thereby ensuring the operational reliability of the drive assembly 30. It should be noted that when the value of ∠HAG / ∠MAN is in the range [8, 12], as the value of ∠HAG / ∠MAN increases, the reaction speed of the drive assembly 30 increases and the structural reliability decreases.
[0146] In some embodiments 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 R1, and the distance from the center of the connecting portion 321 to the rotation center of the second transmission member 33 is R2. The distance from the rotation axis of the first transmission member 32 to the rotation center of the second transmission member 33 is R3. R1, R2, and R3 satisfy the following equation: R3 = R1 × cos(∠MPN / 2) + R2 × (∠MAN / 2).
[0147] When the air deflector 40 is rotated from a closed position to its maximum opening angle, the sliding stroke of the second transmission member 33 is Y, where Y satisfies the following equation: Y = 2πr × [(∠MPN / 2) / 360°]. In this way, the sliding stroke of the second transmission member 33 can be predefined, allowing the air deflector 40 to open to its maximum angle, thereby increasing the airflow range of the indoor unit 10.
[0148] In some embodiments of the present disclosure, as shown in FIG12 , the second transmission member 33 further includes a second stopper 335 and a third stopper 336. The second stopper 335 and the third stopper 336 are disposed at both ends of the second transmission member 33 along the length direction and can selectively abut against both ends of the second housing 31. When the second stopper 335 slides until it abuts against one end of the second housing 31, it can limit the second transmission member 33, preventing the second transmission member 33 from sliding further, thereby preventing the second transmission member 33 from sliding too far and sliding out of the second housing 31. The space outside the second housing 31 restricts the operation of the drive assembly 30.
[0149] In some embodiments of the present disclosure, referring to FIG. 14 , the second transmission member 33 further includes a first limiting portion 334 , which is, for example, a bar-shaped hole.
[0150] The second housing 31 further includes a limiting rod 317, which can be configured as a long straight rod. The limiting rod 317 cooperates with the first limiting portion 334 of the second transmission member 33 to lock the second transmission member 33's vertical translational and rotational freedoms. The second transmission member 33 can slide along the length of the limiting rod 317. When the air deflector 40 is in the closed state, the limiting rod 317 is located in the middle of the first limiting portion 334.
[0151] As shown in Figure 14, the length of the limit rod 317 is defined as L1, and the length of the first limit part 334 is L2, then L1 and L2 satisfy: L2>L1, that is, when the first shaft 341 slides to one of the two ends of the first transmission part 311, the two ends in the length direction of the limit rod 317 are respectively spaced apart from the first limit part 334. In this way, it is possible to prevent the limit rod 317 from limiting the sliding distance of the second transmission member 33, thereby avoiding the problem that the second transmission member 33 cannot engage the first rotating shaft 41 or the second rotating shaft 42 of the air guide plate 40 due to insufficient sliding distance of the second transmission member 33.
[0152] When the first shaft 341 slides to one end of the first transmission portion 311 in the length direction, the second transmission member 33 engages the first rotating shaft 41 or the second rotating shaft 42 of the air deflector 40 within the first rotating portion 312 or the second rotating portion 313. For example, the first rotating shaft 41 is engaged within the first rotating portion 312. At this time, the first rotating shaft 41 can abut against the second transmission member 33. The second transmission member 33 provides support for the first rotating shaft 41.
[0153] In some embodiments of the present disclosure, the blocking portion 331 includes two support points 3311, which are the points where the first rotating shaft 41 or the second rotating shaft 42 abuts the second transmission member 33. The two support points 3311 are respectively disposed at the ends of the blocking portion 331 in the longitudinal direction. 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. The second transmission member 33 extends from the support point 3311 at one end in a direction away from the limiting rod 317, such that L3 and L4 satisfy the following relationship: L4>L3.
[0154] In some embodiments of the present disclosure, the length relationship between L1 and L4 satisfies: 2L1≤L4≤3L1. In this way, the second transmission member 33 can have sufficient sliding stroke in the length direction to achieve the engagement of the second transmission member 33 with the air guide plate 40, while avoiding the inability to effectively engage with the air guide plate 40 due to excessive sliding stroke, so that the second transmission member 33 has better guidance.
[0155] In some embodiments of the present disclosure, as shown in Figure 15, the distance between the axis centers of the first rotating shaft 41 and the second rotating shaft 42 of the air guide plate 40 is L5. When the air guide plate 40 is in a closed state, the length L4 of the second transmission member 33 is greater than or equal to the distance L5 between the axis centers of the rotating shafts at both ends of the second transmission member 33. In this way, the air guide plate 40 can be effectively abutted against the second transmission member 33 in the closed state, preventing the first rotating shaft 41 or the second rotating shaft 42 of the air guide plate 40 from being separated from the first shell 101. At the same time, when the air guide plate 40 rotates, the second transmission member 33 can slide and engage the first rotating shaft 41 or the second rotating shaft 42 of the air guide plate 40 with the first shell 101, preventing the air guide plate 40 from being separated from the second shell 31 when rotating, thereby improving the operating reliability of the drive assembly 30.
[0156] As shown in FIG16 , in some embodiments of the present disclosure, the limiting rod 317 includes an oil reservoir 3171 (e.g., an oil tank) and a limiting rod body 3173. The oil reservoir 3171 is recessed toward the interior of the limiting rod 317 and is configured to store lubricating grease. The oil reservoir 3171 is disposed on at least one of the side of the limiting rod body 3173 that is close to the first transmission member 32 or the side that is away from the first transmission member 32. The oil reservoirs 3171 are spaced apart along the length of the limiting rod 317.
[0157] In some embodiments of the present disclosure, the groove depth of the oil reservoir 3171 ranges from 0.1 to 0.8 mm. In this way, the contact area between the second transmission member 33 and the limiting rod 317 is reduced, thereby reducing the frictional resistance generated when the second transmission member 33 and the limiting rod 317 slide relative to each other, improving the kinematic mechanical properties of the second transmission member 33, and during the long-term operation of the entire drive assembly 30, the lubricating grease applied to the contact surface between the limiting rod 317 and the second transmission member 33 and participating in the friction will slowly be consumed, and the lubricating grease in the oil reservoir 3171 will slowly seep out and be applied to the friction surface between the limiting rod 317 and the second transmission member 33 as the components of the drive assembly 30 reciprocate, thereby improving the reliability of the operation of the drive assembly 30. During the reciprocating motion of the second transmission member 33, some of the seeped lubricating grease will be recovered into the oil reservoir 3171, reducing the loss of lubricating grease.
[0158] The limiting rod 317 further includes protrusions 3172, which are disposed at both ends of the limiting rod body 3173 in the longitudinal direction and are positioned adjacent to the oil reservoir 3171. In some embodiments of the present disclosure, the protrusions 3172 may be disposed on at least one of the two longitudinal sides of the limiting rod 317, thereby ensuring that the oil reservoir 3171 at the end of the second transmission member 33 can store lubricating grease.
[0159] As shown in Figure 22, in some embodiments of the present disclosure, the indoor unit 10 also includes a micro switch 14, which is arranged on the second shell 31 and is configured to sense the time state of the first transmission member 32 returning to the center position, and at the same time derive the wind guide plate 40 from being retracted to the center position of the shutdown state.
[0160] The microswitch 14 is electrically connected to the driver 36. The first transmission member 32 also includes a first mating portion 327. The mating protrusion 327 is disposed on the first sub-transmission member 322. The mating protrusion 327 selectively contacts the microswitch 14 to control the start and stop of the driver 36. For example, when the first transmission member 32 rotates to drive the mating protrusion 327 into contact with the microswitch 14, the driver 36 stops operating. When the first transmission member 32 rotates to drive the mating protrusion 327 out of contact with the microswitch 14, the driver 36 starts operating.
[0161] When the air conditioner 1 is in the off state, the driver 36 drives the driver body 361 to rotate clockwise, and the driver body 361 drives the first transmission member 32 to rotate counterclockwise. The controller records the number of step pulses Q+Q×10% steps given to the driver 36. When the drive assembly 30 reaches the position of Q steps, the drive motor 362 will continue to stall for Q×10% steps. At this time, the micro switch 14 can eliminate the motion error of the drive assembly 30 and the motion error caused by the driver's step loss and other external uncontrollable factors, ensuring that the mechanism moves to the correct position. When the shutdown procedure is initiated, the driver 36 drives the driver body 361 to rotate in the opposite direction. When the first mating portion 327 of the first transmission member 32 touches the contact of the micro switch 14 during the process of returning to the center position, the controller will stop supplying pulses to the driver, and the system will then detect that it is in the off state.
[0162] It should be noted that motor stall is a situation in which the motor still outputs torque when the speed is 0.
[0163] When the air conditioner 1 operates in the heating mode, the driving member 36 drives the first transmission member 32 to rotate counterclockwise, and the second transmission member 33 moves toward the second clamping portion 44 under the drive of the third transmission member 37, and locks the second clamping portion 44 through the second clamping portion 44 and the third clamping portion 315, while releasing the first clamping portion 43 and pushing the air guide plate 40 to flip upward. At this time, the air conditioner 1 starts to blow air, and the air guide plate 40 guides the wind to the lower part.
[0164] When the air conditioner 1 operates in the cooling mode, the driving member 36 drives the first transmission member 32 to rotate clockwise, and the second transmission member 33 moves toward the first clamping portion 43 under the drive of the third transmission member 37, and locks the first clamping portion 43 through the first clamping portion 43 and the fourth clamping portion 332, while releasing the second clamping portion 44, pushing the air guide plate 40 to flip downward. At this time, the air conditioner 1 starts to blow air, and the air guide plate 40 guides the wind to the upper part.
[0165] When the air conditioner 1 is operating in the swing air supply mode, if it is determined that the air conditioner 1 is operating in the heating mode, the air guide plate 40 swings to the limit position, and normal air supply is controlled. If it is determined that the user requires the air guide plate 40 to swing for air supply, the drive motor 362 rotates counterclockwise Q steps. The air guide plate 40 rotates counterclockwise Q steps and stops after reaching the preset point. Then the drive motor 362 rotates clockwise, and the air guide plate 40 moves clockwise Q steps back to the heating limit position. This logic repeats for 15 minutes, and then the limit point reset procedure is initiated: when the air guide plate 40 reaches the preset point, the drive motor 362 rotates forward, and the air guide plate 40 moves clockwise Q steps back to the heating dead point position, and continues to rotate Q×10% to stall, thereby better completing the reset action.
[0166] Those skilled in the art will understand that the scope of the present disclosure is not limited to the above specific embodiments, and that certain elements of the embodiments may be modified and replaced without departing from the spirit of the present application. The scope of the present application is limited by the appended claims.
