Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a motion module of an air conditioner and the air conditioner. Background Art

[0002] In the related art, the moving parts in the air conditioner (such as the lifting door on the cabinet unit and the windless module on the wall-mounted unit) are usually moved up and down by the cooperation of guide rails, gears, and racks. During the movement process, the driving motors with different torques are generally matched according to the torque required for operation, or a large torque is achieved by adding a reduction mechanism. When the driving moving part moves in the same direction as the direction of gravity, the torque required is small, and when the driving moving part moves in the opposite direction to the direction of gravity, the torque required is large. Therefore, the matching motor is generally designed according to the torque required for anti-gravity. As a result, the heavier the moving part, the larger the motor or the slower the speed, the larger the installation space volume of the motor or the reduction mechanism, the limited usage scenarios, the higher the gear strength requirements, and the higher the cost. In addition, after the motor is powered off, the moving part will rebound due to the gravity of the moving part, which may affect the appearance of the closing effect. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a motion module for an air conditioner, which requires a small driving torque, can be designed in a miniaturized manner, and can operate without deceleration.

[0004] The present invention also provides an air conditioner having the motion module.

[0005] According to the first aspect of the present invention, the motion module of the air conditioner includes: a moving part; a driving mechanism connected to the moving part to drive the moving part to move up and down; an anti-gravity mechanism connected to the moving part, and the anti-gravity mechanism is configured to apply a force to the moving part when the moving part moves up and down to overcome or offset at least part of the gravity of the moving part.

[0006] According to an embodiment of the present invention, the motion module of an air conditioner is provided with an anti-gravity mechanism. When the moving part moves up and down, the anti-gravity mechanism applies a force to the moving part to overcome or offset at least a portion of the force of gravity. As a result, when the moving part moves upward, it only needs to overcome the frictional resistance generated during movement and the portion of gravity not offset by the anti-gravity mechanism. Consequently, when the moving part moves upward, the driving mechanism only needs to provide the torque required to overcome the frictional resistance and the portion of gravity not offset by the anti-gravity mechanism to drive the moving part upward. This reduces the torque of the driving mechanism, facilitating torque minimization. This reduces the material requirements for gears and other components in the driving mechanism, avoiding tooth breakage and other issues, improving the reliability of the driving mechanism, and reducing the size of the driving mechanism. This not only reduces costs but also significantly reduces the space occupied by the driving mechanism. This reduces the overall size of the air conditioner, enhancing its appearance, or freeing up installation space for other components of the air conditioner, thereby optimizing the functionality of the air conditioner. Furthermore, it prevents springback of the moving part caused by excess torque.

[0007] According to some embodiments of the present invention, the constant force module is a constant force spring, which includes a winding portion formed in a planar spiral shape, the winding portion having a first connecting end and a second connecting end, the first connecting end being fixedly connected to the housing of the air conditioner, and the second connecting end being fixedly connected to the moving part.

[0008] According to some embodiments of the present invention, there are multiple constant force springs.

[0009] According to some embodiments of the present invention, the anti-gravity mechanism includes: a fixed shaft, which is fixed on the housing of the air conditioner; a constant force gear, which is sleeved on the outside of the fixed shaft; a torsion spring, which is arranged on the inside of the constant force gear, one end of the torsion spring is fixedly connected to the fixed shaft, and the other end of the torsion spring is fixedly connected to the constant force gear; a constant force rack, which is arranged on the moving part and meshes with the constant force gear.

[0010] According to some embodiments of the present invention, a first groove portion is provided on the fixed shaft, and one end of the torsion spring is clamped in the first groove portion, and / or a second groove portion is provided on the inner circumference of the fixed force gear, and the other end of the torsion spring is clamped in the second groove portion.

[0011] According to some embodiments of the present invention, the fixed force rack and the moving part are integrally formed.

[0012] According to some embodiments of the present invention, the anti-gravity mechanism includes: an elastic member, one end of which is fixed to the housing of the air conditioner; a pulley assembly, the pulley assembly including a rotating shaft, a first pulley and a second pulley, the first pulley and the second pulley can rotate synchronously around the rotating shaft, the first pulley is located on the inner side of the second pulley, a first pull wire is wound around the outer peripheral wall of the first pulley, and a second pull wire is wound around the outer peripheral wall of the second pulley, the free end of the first pull wire is connected to the elastic member, and the free end of the second pull wire is connected to the moving member, when the moving member is in the initial position, the torque of the elastic member is M1, and when the moving member moves up and down, the torque of the elastic member is M2, and M1 is substantially equal to M2.

[0013] According to some embodiments of the present invention, the first pulley is formed in an elliptical shape, and the second pulley is formed in a circular shape.

[0014] According to some embodiments of the present invention, the driving mechanism includes: a driving rack connected to the moving part, a driving gear engaged with the driving rack; and a driving part connected to the driving gear to drive the driving gear to rotate.

[0015] According to some embodiments of the present invention, the driving rack and the moving part are integrally formed.

[0016] An air conditioner according to an embodiment of a second aspect of the present invention includes the motion module of the air conditioner according to the embodiment of the first aspect of the present invention.

[0017] According to an embodiment of the second aspect of the present invention, an air conditioner is provided with a motion module according to the first aspect of the present invention, and an anti-gravity mechanism is provided. When the moving part moves up and down, the anti-gravity mechanism applies a force to the moving part to overcome or offset at least a portion of the gravity. As a result, when the moving part moves upward, it only needs to overcome the frictional resistance generated during the movement and the gravity that is not offset by the anti-gravity mechanism. Therefore, when the moving part moves upward, the driving mechanism only needs to provide a torque that overcomes the frictional resistance and the gravity that is not offset by the anti-gravity mechanism to drive the moving part upward. This reduces the torque of the driving mechanism, which is conducive to minimizing the torque, lowering the material requirements for gears and other components in the driving mechanism, avoiding tooth breakage and other problems, improving the reliability of the driving mechanism, and reducing the size of the driving mechanism. This not only reduces costs but also greatly reduces the space occupied by the driving mechanism. This can reduce the overall size of the air conditioner, improve the appearance of the air conditioner, or free up installation space for other components of the air conditioner, which is conducive to optimizing the function of the air conditioner. At the same time, it can also prevent the rebound of the moving part caused by excess torque.

[0045] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0046] Hereinafter, a motion module of the air conditioner 1000 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0047] like Figure 7 As shown, the motion module of the air conditioner 1000 according to the first embodiment of the present invention includes: a moving part 1, a driving mechanism 2 and an anti-gravity mechanism 3.

[0048] In some embodiments of the present invention, the moving part 1 may be Figures 1-4The windless module on the air conditioner hanging unit shown in FIG, or the moving part 1 can also be Figure 5 and Figure 6 Specifically, refer to the lifting door on the air conditioner cabinet shown in FIG. Figure 2-Figure 4 , the windless module can move in the up and down directions to switch the air outlet mode of the air conditioner 1000. Figure 5 and Figure 6 The lifting door can move in the up and down directions to open or close the air outlet of the air conditioner cabinet.

[0049] Among them, the driving mechanism 2 is connected to the moving part 1 and is used to drive the moving part 1 to move up and down. The anti-gravity mechanism 3 is connected to the moving part 1. The anti-gravity mechanism 3 is configured to apply a force to the moving part 1 when the moving part 1 moves up and down to overcome or offset at least part of the gravity of the moving part 1.

[0050] That is to say, the force applied by the anti-gravity mechanism 3 to the moving part 1 can overcome or offset part of the gravity of the moving part 1 when the moving part 1 moves. At this time, the component of the force applied by the anti-gravity mechanism 3 to the moving part 1 in the vertical direction is smaller than the gravity of the moving part 1, and the direction of the component of the force applied by the anti-gravity mechanism 3 to the moving part 1 in the vertical direction is opposite to the direction of gravity.

[0051] Alternatively, the force applied by the anti-gravity mechanism 3 to the moving part 1 can overcome or offset the entire weight of the moving part 1 when the moving part 1 moves. In this case, the vertical component of the force applied by the anti-gravity mechanism 3 to the moving part 1 is equal to the weight of the moving part 1, and the direction of the vertical component of the force applied by the anti-gravity mechanism 3 to the moving part 1 is opposite to the direction of gravity. It will be understood that when the force applied by the anti-gravity mechanism 3 to the moving part 1 can overcome or offset the entire weight of the moving part 1 when the moving part 1 moves, the vertical component of the force applied by the anti-gravity mechanism 3 to the moving part 1 only needs to be substantially equal to the weight of the moving part 1, i.e., they do not need to be strictly equal.

[0052] Thus, the anti-gravity mechanism 3 applies a force to the moving part 1 to overcome or offset at least part of the gravity of the moving part 1, so that when the moving part 1 moves upward, it only needs to overcome the friction resistance generated during the movement and the gravity that is not offset by the above-mentioned force. Therefore, when the moving part 1 moves upward, the driving mechanism 2 only needs to provide a torque to overcome the friction resistance and the torque of the gravity that is not offset by the above-mentioned force to drive the moving part 1 to move upward, thereby reducing the torque of the driving mechanism 2, which not only reduces the cost, but also greatly reduces the space occupied by the driving mechanism 2, thereby reducing the overall volume of the air conditioner 1000, making the appearance of the air conditioner 1000 better, or freeing up installation space for other components of the air conditioner 1000, such as the fresh air module, which is conducive to increasing the fresh air volume.

[0053] Since the torque required by the driving mechanism 2 during the upward movement of the moving member 1 is greater than the torque required by the driving mechanism 2 during the downward movement of the moving member 2, the torque of the driving mechanism 2 can be reduced by reducing the torque required during the upward movement of the moving member 1.

[0054] In some optional embodiments of the present invention, the force applied by the anti-gravity mechanism 3 to the moving part 1 can overcome or offset the entire gravity of the moving part 1 when the moving part 1 moves, so that when the moving part 1 moves upward and downward, it only needs to overcome the friction resistance generated during the movement. Therefore, no matter whether the moving part 1 moves upward or downward, the driving mechanism 2 only needs to provide a torque to overcome the friction resistance to drive the moving part 1 to move up and down, thereby reducing the torque of the driving mechanism 2, so that the torque that the driving mechanism 2 needs to output is basically the same, and non-deceleration operation can be achieved when the moving part 1 moves upward.

[0055] This minimizes torque, reduces material requirements for gears and other components in the drive mechanism 2, avoids tooth breakage, and improves the reliability of the drive mechanism 2. Furthermore, the volume of the drive mechanism 2 is minimized, which not only reduces costs but also significantly reduces the space occupied by the drive mechanism 2. This reduces the overall volume of the air conditioner 1000, improving the appearance of the air conditioner 1000 and freeing up installation space for other components of the air conditioner 1000, thereby optimizing the functionality of the air conditioner 1000. Furthermore, this prevents springback of the moving part 1 caused by excess torque.

[0056] For example, in some embodiments of the present invention, the moving part 1 is a wind-free module, weighing approximately 1000g. Assuming a friction coefficient of 0.5, in conventional solutions, the maximum resistance that the moving part 1 must overcome when moving up and down is approximately 1500g, requiring a 35-gauge drive motor. However, in this application, by adding the anti-gravity mechanism 3, the maximum resistance that the moving part 1 must overcome when moving up and down is only equivalent to 500g, allowing for a smaller 24-gauge motor.

[0057] It is understood that the location and number of the anti-gravity mechanisms 3 can be adjusted based on actual circumstances. For example, the anti-gravity mechanisms 3 can be located in the middle, upper, lower, left, or right side of the moving part 1. The number of anti-gravity mechanisms 3 can also be adjusted based on the gravity of the moving part 1. This is not a limitation of the present invention.

[0058] According to the motion module of the air conditioner 1000 according to the embodiment of the present invention, an anti-gravity mechanism 3 is provided. When the moving part 1 moves up and down, the anti-gravity mechanism 3 applies a force to the moving part 1 for overcoming or offsetting at least part of the gravity of the moving part 1, so that when the moving part 1 moves upward, it only needs to overcome the friction resistance generated during the movement and the gravity that is not offset by the above-mentioned force. Therefore, when the moving part 1 moves upward, the driving mechanism 2 only needs to provide a torque to overcome the friction resistance and the gravity that is not offset by the above-mentioned force to drive the moving part 1 to move upward, thereby reducing the torque of the driving mechanism 2, lowering the requirements for materials such as gears in the driving mechanism 2, avoiding problems such as broken teeth, improving the reliability of the driving mechanism 2, and reducing the volume of the driving mechanism 2. This not only reduces the cost, but also greatly reduces the space occupied by the driving mechanism 2, thereby reducing the overall volume of the air conditioner 1000, making the appearance of the air conditioner 1000 more beautiful, or freeing up installation space for other components of the air conditioner 1000, which is conducive to optimizing the function of the air conditioner 1000.

[0059] According to some embodiments of the present invention, the force exerted by anti-gravity mechanism 3 on moving part 1 is a constant force, capable of overcoming or offsetting the entire weight of moving part 1. Specifically, the vertical component of this force is equal to or approximately equal to the weight of moving part 1, and its direction is opposite to the weight of moving part 1. This ensures that the torque required to be output by drive mechanism 2 is substantially consistent, enabling the moving part 1 to operate without deceleration during upward motion.

[0060] According to some embodiments of the present invention, referring to Figure 7 The anti-gravity mechanism 3 is a constant force spring 31, which includes a winding portion 311 formed in a planar spiral shape. The winding portion 311 has a first connecting end and a second connecting end 312. The first connecting end is fixedly connected to the shell of the air conditioner 1000, and the second connecting end 312 is fixedly connected to the moving part 1.

[0061] For example, the coiled portion 311 is formed by coiling metal sheets in circles, with each coil of metal sheets tightly connected. Because the thickness of the metal sheets is relatively small relative to their diameter, the diameter of the constant-force spring 31 does not change much when the constant-force spring 31 is stretched, so the force required for stretching remains essentially the same. While a conventional spring increases its elastic force the longer it is stretched, the constant-force spring 31 maintains essentially the same deformation when rotated through a certain angle, resulting in a very small range of elastic force fluctuations and a stable output force.

[0062] Thus, the constant force spring 31 can be used to apply a force to the moving part 1 to offset at least part of the gravity of the moving part 1, so that when the moving part 1 moves upward, it only needs to overcome the friction resistance generated during the movement and the gravity that is not offset. Therefore, when the moving part 1 moves upward, the driving mechanism 2 only needs to provide a torque to overcome the friction resistance and the gravity that is not offset to drive the moving part 1 to move upward, thereby reducing the torque of the driving mechanism 2, which not only reduces the cost, but also greatly reduces the space occupied by the driving mechanism 2, thereby reducing the overall volume of the air conditioner 1000, and the anti-gravity mechanism 3 has a simple structure and is easy to implement.

[0063] According to some embodiments of the present invention, there are multiple constant force springs 31. In the description of the present invention, the meaning of "multiple" is two or more. For example, in Figure 5 In the example, there may be four constant force springs 31, one each on the upper side, lower side, left side, and right side of the moving part 1. This reduces the force exerted by each constant force spring 31 on the moving part 1, thereby lowering the specification requirements for the constant force springs 31 and further reducing the cost of the motion module.

[0064] In some embodiments of the present invention, multiple constant force springs 31 are spaced apart in the circumferential direction of the moving part 1. This makes the force applied to the moving part 1 more uniform, the movement process smoother, and the force applied by each constant force spring 31 on the moving part 1 less, thereby reducing the specification requirements for the constant force springs 31 and further reducing the cost of the motion module.

[0065] According to other embodiments of the present invention, Figures 8-10 The anti-gravity mechanism 3 includes: a fixed shaft 321, a fixed force gear 322, a torsion spring 323 and a fixed force rack 324. The fixed shaft 321 is fixed to the housing of the air conditioner 1000, and the fixed force gear 322 is sleeved on the fixed shaft 321; the torsion spring 323 is arranged on the inner side of the fixed force gear 322, and one end of the torsion spring 323 (for example, Figure 9 The inner end of the torsion spring 323 is fixedly connected to the fixed shaft 321, and the other end of the torsion spring 323 (for example, Figure 9 The outer end of the middle torsion spring 323 is fixedly connected to the fixed force gear 322; the fixed force rack 324 is set on the moving part 1, and the fixed force rack 324 is engaged with the fixed force gear 322.

[0066] Reference Figures 8-11 The fixed rack 324 extends in the vertical direction. When the moving part 1 moves up and down, the fixed rack 324 moves with the moving part 1, thereby driving the fixed gear 322 to rotate. When the fixed gear 322 rotates, the torsion spring 323 generates a torsional force. The vertical component of this torsional force can overcome or offset at least part of the gravity of the moving part 1.

[0067] For example, in some embodiments of the present invention, the vertical component of the torsional force is substantially equal in magnitude and opposite in direction to the gravity of the moving part 1. Thus, the anti-gravity mechanism 3 can apply a force to the moving part 1, so that when the moving part 1 moves upward or downward, it only needs to overcome the frictional resistance generated during the movement. Therefore, regardless of whether the moving part 1 moves upward or downward, the torque that the drive mechanism 2 needs to output is substantially the same. In this case, the drive mechanism 2 only needs to provide the torque to overcome the frictional resistance to drive the moving part 1 up and down, thereby reducing the torque of the drive mechanism 2. This not only reduces costs but also greatly reduces the space occupied by the drive mechanism 2, thereby reducing the overall volume of the air conditioner 1000. Furthermore, the anti-gravity mechanism 3 has a simple structure and is easy to manufacture.

[0068] According to some embodiments of the present invention, a first groove portion 3211 is provided on the fixed shaft 321, and one end of the torsion spring 323 is clamped in the first groove portion 3211, and / or a second groove portion 3221 is provided on the inner circumferential surface of the fixed force gear 322, and the other end of the torsion spring 323 is clamped in the second groove portion 3221.

[0069] Specifically, the first groove 3211 may be provided only on the fixed shaft 321, so that one end of the torsion spring 323 is engaged in the first groove 3211. Alternatively, the second groove 3221 may be provided only on the inner circumferential surface of the stationary gear 322, so that the other end of the torsion spring 323 is engaged in the second groove 3221. Alternatively, the first groove 3211 may be provided on the fixed shaft 321, so that one end of the torsion spring 323 is engaged in the first groove 3211, while the second groove 3221 may be provided on the inner circumferential surface of the stationary gear 322, so that the other end of the torsion spring 323 is engaged in the second groove 3221. This makes the connection between the torsion spring 323 and the fixed shaft 321 and / or the stationary gear 322 more stable and reliable, thereby improving the reliability and stability of the anti-gravity mechanism 3 and making the movement of the moving part 1 smoother.

[0070] According to some embodiments of the present invention, the fixed force rack 324 is integrally formed with the moving part 1. This simplifies the structure of the moving module, improves the assembly efficiency of the moving module, and increases the structural strength of the moving part 1.

[0071] According to some further embodiments of the present invention, Figure 12-15 The anti-gravity mechanism 3 includes an elastic member 331 and a pulley assembly 332. One end of the elastic member 331 is fixed to the housing of the air conditioner 1000. Alternatively, the elastic member 331 may be a spring, a bellows, or the like. The elastic member 331 may be fixed to the housing of the air conditioner 1000 via a mounting bracket, thereby conveniently and securely securing the elastic member 331 to the housing of the air conditioner 1000.

[0072] The pulley assembly 332 includes a rotating shaft 3321, a first pulley 3322, and a second pulley 3323. The first pulley 3322 and the second pulley 3323 are capable of synchronously rotating about the rotating shaft 3321. The first pulley 3322 is located inside the second pulley 3323, and the first pulley 3322 and the second pulley 3323 are spaced apart from each other. A first cable 3324 is wound around the outer wall of the first pulley 3322, and a second cable 3325 is wound around the outer wall of the second pulley 3323. The free end of the first cable 3324 is connected to the elastic member 331, and the free end of the second cable 3325 is connected to the moving member 1. When the moving member 1 is in the initial position, the torque of the elastic member 331 is M1. When the moving member 1 moves up and down, the torque of the elastic member 331 is M2, and M1 and M2 are substantially equal (i.e., M1 is equal to or approximately equal to M2).

[0073] Specifically, when the moving part 1 moves up and down, the moment M generated by gravity is constant. Since the gravity and the lever arm remain unchanged, the moment M generated by the gravity of the moving part 1 remains unchanged during the movement process.

[0074] Initial position (such as Figure 12 and Figure 13 As shown), the tension F1 generated by the elastic member 331 is equal to L1*u, and the torque M1 of the elastic member 331 is equal to F1*x1=L1*u*x1; wherein L1 is the initial stretching length of the elastic member 331, u is the elastic coefficient of the elastic member 331, and x1 is the lever arm of the elastic member 331 when the moving member 1 is in the initial position.

[0075] When the moving part 1 moves up and down (such as Figure 14 and Figure 15 As shown in FIG1 , the tension F2 generated by the elastic member 331 is equal to L2*u, and the torque M2 of the elastic member 331 is equal to F2*x2=L2*u*x2. Wherein, L2 is the stretched length of the elastic member 331 when the moving member 1 moves up and down. x2 is the lever arm of the elastic member 331 when the moving member 1 moves up and down. Since L2 is greater than L1, when the value of L2 increased relative to L1 is equal to the value of X2 decreased relative to X1, M1 and M2 can be made substantially equal (i.e., M1 is equal to or approximately equal to M2), thereby achieving constant torque. Furthermore, a constant force can be applied to the moving member 1 through the anti-gravity mechanism 3, so that the torque of the elastic member 331 can offset at least part of the torque generated by gravity.

[0076] In this way, the driving mechanism 2 only needs to provide the torque to overcome the friction resistance and the gravity that is not offset by the above-mentioned forces to drive the moving part 1 to move upward, thereby reducing the torque of the driving mechanism 2, with a simple structure and ingenious design.

[0077] In some embodiments of the present invention, the torque of the elastic member 331 is always balanced with the torque generated by gravity, so that the driving mechanism 2 only needs to provide a torque to overcome the frictional resistance to drive the moving member 1 up and down, thereby reducing the torque of the driving mechanism 2, with a simple structure and ingenious design.

[0078] According to some embodiments of the present invention, the first pulley 3322 is formed into an elliptical shape, and the second pulley 3323 is formed into a circular shape. Thus, when the moving part 1 moves up and down, it can be ensured that the lever arm of the first pull wire 3324 becomes shorter and the lever arm of the second pull wire 3325 remains unchanged. The anti-gravity mechanism 3 applies a force to the moving part 1, so that when the moving part 1 moves upward, it only needs to overcome the friction resistance generated during the movement and the gravity that is not offset by the above-mentioned force. Therefore, when the moving part 1 moves upward, the driving mechanism 2 only needs to provide a torque that overcomes the friction resistance and the gravity that is not offset by the above-mentioned force to drive the moving part 1 to move upward, thereby reducing the torque of the driving mechanism 2. In addition, the anti-gravity mechanism 3 has a simple structure and a clever design.

[0079] According to some embodiments of the present invention, the drive mechanism 2 includes: a drive rack 21, a drive gear 22, and a drive member 23. The drive rack 21 is connected to the moving part 1, the drive gear 22 is engaged with the drive rack 21, and the drive member 23 is connected to the drive gear 22 to drive the drive gear 22 to rotate. The drive member 23 can be a motor. The drive gear 22 can be connected to the motor shaft of the motor. When the drive member 23 is working, it can drive the drive gear 22 to rotate, causing the drive rack 21 to move up and down, and then drive the drive member 23 to move up and down. In this way, the moving part 1 can be conveniently driven to move up and down, and the structure of the drive mechanism 2 is simple and the cost is low.

[0080] According to some embodiments of the present invention, the driving rack 21 is integrally formed with the moving part 1 , thereby simplifying the structure of the moving module, improving the assembly efficiency of the moving module, and increasing the structural strength of the moving part 1 .

[0081] The air conditioner 1000 according to the second embodiment of the present invention comprises the motion module of the air conditioner 1000 according to the first embodiment of the present invention. The air conditioner 1000 can be a wall mounted air conditioner or a cabinet air conditioner.

[0082] According to the air conditioner 1000 of the second embodiment of the present invention, by providing the motion module of the air conditioner 1000 of the first embodiment of the present invention, and by providing an anti-gravity mechanism 3, when the moving part 1 moves up and down, the anti-gravity mechanism 3 can apply a force to the moving part 1 for overcoming or offsetting at least part of the gravity of the moving part 1, so that when the moving part 1 moves upward, it only needs to overcome the friction resistance generated during the movement and the gravity that is not offset by the above-mentioned force. Therefore, when the moving part 1 moves upward, the driving mechanism 2 only needs to provide a torque to overcome the friction resistance and the gravity that is not offset by the above-mentioned force to drive the moving part 1 upward, thereby reducing the torque of the driving mechanism 2, lowering the requirements for the materials of the gears and the like in the driving mechanism 2, avoiding problems such as broken teeth, improving the reliability of the driving mechanism 2, and reducing the volume of the driving mechanism 2. This not only reduces the cost, but also greatly reduces the space occupied by the driving mechanism 2, thereby reducing the overall volume of the air conditioner 1000, making the appearance of the air conditioner 1000 more beautiful, or freeing up installation space for other components of the air conditioner 1000, which is conducive to optimizing the function of the air conditioner 1000.
