Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, and in particular to an air conditioner. BACKGROUND

[0002] In the field of air conditioning equipment, especially in the cabinet machine product with air adjusting function, the accurate control of the air outlet grille and the air deflector is crucial to achieve comfortable and efficient air conditioning.

[0003] In the related art, when the cabinet machine starts the air adjusting function, the air outlet grille needs to reciprocate within a preset angle range to preliminarily change the air outlet direction of the air outlet, and the air deflector installed on the air outlet grille also rotates synchronously. On this basis, in order to further finely adjust the air outlet direction, a driving member is usually arranged at the rotating axis of the air outlet grille to drive the air deflector to swing around its own swing axis.

[0004] However, with the continuous rotation of the air outlet grille, the wire connected to the driving member frequently bears tension and torsion, which easily causes the wire to be entangled or bent, or other components on the driving member to be disconnected due to reciprocating rotation, and the wire is entangled or bent at this position to break, thereby causing the driving member driving the air deflector to swing to fail to obtain power supply, and the function of the air deflector to finely adjust the air outlet direction to fail. SUMMARY

[0005] The present application discloses an air conditioner which can avoid the problems of wire entanglement, bending and breaking of the motor, and the risk of loose or ineffective connection of other connecting components on the motor.

[0006] To achieve the above-mentioned purpose, the present application discloses an air conditioner, comprising: a cabinet machine, wherein the cabinet machine comprises: a machine shell, wherein the machine shell is provided with an air outlet; a fixed support, wherein the fixed support is fixedly arranged on the machine shell and located at the air outlet; a first air outlet grille, wherein the first air outlet grille is rotatably arranged on the fixed support around a first axis; a plurality of air deflectors, wherein the plurality of air deflectors are arranged along a second axis and rotatably arranged on the first air outlet grille around the second axis, and the plurality of air deflectors are drivingly connected, so that when the first air outlet grille rotates relative to the fixed support, the first air outlet grille can drive the plurality of air deflectors to rotate to change the air outlet angle of the air outlet, and the first axis is perpendicular to the second axis; a first driving assembly, wherein the first driving assembly is used to drive the first air outlet grille to rotate, and the first driving assembly comprises: a first motor, wherein the first motor is fixed on the fixed support; a second driving assembly capable of driving one of the air deflectors to swing around the second axis, the second driving assembly comprising: a second motor fixed on the fixed support, a rotation axis of the second motor being parallel to the first axis; a transmission assembly connected between the second motor and the air deflectors, the transmission assembly comprising: a first transmission part connected with an output shaft of the second motor and configured to rotate around the rotation axis of the second motor; a second transmission part, one end of the second transmission part being connected to the first transmission part, and the other end of the second transmission part being connected to at least one of the air deflectors, the second transmission part being configured to move at least a part of the second transmission part along a radial direction of the first air outlet grille when the first transmission part rotates relative to the first air outlet grille, so as to drive the air deflectors to rotate around the second axis.

[0007] In this way, the second motor does not need to reciprocate with the moving part and other connecting components supplied with power from outside, avoiding that the wire is frequently subjected to tensile stress and torsional stress, and fundamentally eliminating the problems of wire winding, bending and breaking. The second motor itself does not participate in the rotation, and there is no risk of loose or failed connection of components caused by reciprocating rotation, ensuring long-term stable operation of the driving assembly.

[0008] Moreover, the first motor drives the first air outlet grille to rotate, which can quickly realize macro adjustment of the air outlet direction, such as large-scale left-right air sweeping. The second motor drives the air deflectors to swing through the transmission assembly, and the air adjusting action is independent of the rotation of the first air outlet grille, that is, when the first transmission part of the transmission assembly rotates relative to the first air outlet grille, the second transmission part can drive the air deflectors to swing, so that the air deflectors can swing up and down synchronously when the first air outlet grille drives the air deflectors to rotate by a large angle, realizing fine requirements such as fixed-point air supply and soft air diffusion, and improving user comfort.

[0009] The application further provides an air conditioner, the first transmission part comprising a rotating handle fixedly connected with the output shaft of the second motor; the second transmission part comprising a first connecting rod, a sliding block and a second connecting rod connected in sequence, a first end of the first connecting rod being rotationally connected with the rotating handle, and a second end of the first connecting rod being rotationally connected with the sliding block; the sliding block being arranged to slide relative to the second motor along a radial direction of the first air outlet grille, the radial direction of the first air outlet grille being perpendicular to a direction of the rotation axis of the second motor; The first end of the second connecting rod is rotationally connected with the sliding block, the plurality of guide vanes includes a first guide vane, and the second end of the second connecting rod is rotationally connected with the first guide vane.

[0010] In this way, the rigid connecting rod is matched with the sliding block, there is no elastic deformation in the transmission process, the rotation angle of the output end of the second motor can be accurately converted into the swing angle of the guide vane, for example, 180° rotation of the output end of the second motor, a preset distance of the sliding block, and 15° swing of the guide vane, so that the swing angle of the guide vane is controllable and stable, the deviation or disorder of the air outlet direction is avoided, and the precision of fine air regulation is improved.

[0011] The first transmission part includes a rotating handle, a first connecting rod, a sliding block and a second connecting rod, there are no complex components, the number of parts is small, the assembly difficulty is low, and the risk of failure of multiple component cooperation is reduced; the rigid mechanical structure has strong anti-aging and anti-wear abilities, can withstand fatigue loads of reciprocating motion for a long time, avoids transmission failure caused by component aging, and prolongs the service life.

[0012] The application also provides an air conditioner, the middle part of the first air outlet grille is provided with a mounting shell, the mounting shell is provided with a avoiding opening in the direction of the first guide vane, the transmission assembly extends to the first guide vane through the avoiding opening in the mounting shell, the side wall of the avoiding opening is provided with a guide groove in the radial direction of the first air outlet grille, and the sliding block is in sliding connection with the guide groove.

[0013] In this way, the guide groove restricts the lateral deviation or rotation of the sliding block, ensures that the sliding block always moves linearly in the radial direction of the first air outlet grille, avoids additional torque of the first connecting rod and the second connecting rod due to the deviation of the sliding block, and prevents the swing angle deviation or transmission jam of the guide vane.

[0014] The mounting shell contains the transmission components such as the rotating handle, the first connecting rod and the sliding block, only the connecting end of the second connecting rod is exposed, dust and condensed water are prevented from directly adhering to the transmission components, transmission resistance increase or jam caused by rust and dust accumulation of the components is prevented, the transmission components are prevented from being touched or collided by the user or during maintenance, the risk of interference between the grid and other structures during rotation is reduced, and the integrity of the transmission system is protected.

[0015] The application also provides an air conditioner, the first end of the first connecting rod is provided with a first rotation groove, one end of the rotating handle close to the first connecting rod is provided with a first rotation part, the first rotation part extends into the first rotation groove and is in rotation connection with the first rotation groove, and the rotation axis of the first rotation part is parallel to the rotation axis of the second motor. The second end of the first connecting rod is provided with a second rotating groove, and the end of the sliding block close to the first connecting rod is provided with a second rotating part which extends into the second rotating groove and is rotationally connected with the second rotating groove, and the rotating axis of the second rotating part is parallel to the rotating axis of the second motor.

[0016] In this way, the design that the rotating part rotates in the rotating groove allows the first connecting rod to flexibly adjust the angle with the rotating handle and the sliding block during swinging, for example, when the rotating handle rotates to the highest point, the included angle between the first connecting rod and the rotating handle increases, and the first rotating part can synchronously rotate in the first rotating groove to adapt to the angle, avoiding the jam caused by rigid connection; similarly, the connection between the first connecting rod and the sliding block can also adapt to the swinging angle through the rotation of the second rotating part, ensuring smooth transmission without resistance.

[0017] The application also provides an air conditioner, and the end of the sliding block close to the second connecting rod is further provided with a first rotating arm, the first end of the second connecting rod is sleeved on the first rotating arm and is rotationally connected with the first rotating arm, and the extension direction of the first rotating arm is perpendicular to the rotating axis direction of the second motor and the radial direction of the first air outlet grille. The first air deflector is provided with a second rotating arm, the second end of the second connecting rod is sleeved on the second rotating arm and is rotationally connected with the second rotating arm, and the extension direction of the second rotating arm is perpendicular to the rotating axis direction of the second motor and the radial direction of the first air outlet grille.

[0018] In this way, the connection between the second connecting rod and the sliding block and the first air deflector is all the shaft sleeve type rigid connection without transmission gap, the linear motion of the sliding block can be directly converted into the swinging torque of the air deflector through the second connecting rod, and the power transmission efficiency is high; the extension direction of the rotating arm forms the best torque transmission angle with the swinging direction of the first air deflector, and the slight swing of the second connecting rod can drive the air deflector to quickly respond, avoiding the swing delay caused by power loss and improving the air conditioning response speed.

[0019] The application also provides an air conditioner, and a plurality of air deflectors are transmissionally connected through a third connecting rod to swing synchronously.

[0020] In this way, the third connecting rod is connected with the first air deflector and the remaining air deflectors as a bridge, and the swinging power of the first air deflector is synchronously transmitted to all air deflectors, and since the third connecting rod is a rigid or low-deformation component, it will not produce obvious displacement deviation during power transmission, ensuring that the swinging angle, swinging speed and swinging phase of all air deflectors are completely consistent, avoiding the problem that some air deflectors swing lag or have angle deviation.

[0021] The application also provides an air conditioner, and the fixed support comprises: a first annular frame; A connecting arm is attached to the first annular frame, and the second motor is fixed to the connecting arm.

[0022] In this way, the annular structure of the first ring frame can effectively resist the radial force generated when the first air outlet grille rotates by dispersing circumferential stress, such as the centrifugal force when the first air outlet grille rotates and the frictional force with the fixed bracket, so as to avoid the frame from twisting or shifting after long-term use and ensure smooth grille rotation.

[0023] This application also provides an air conditioner, wherein the first air outlet grille includes a second annular frame, the second annular frame is located inside the first annular frame, and the second annular frame is provided with a toothed disc; The first motor is fixed on the first annular frame, and the output end of the first motor is provided with a gear, which meshes with the gear plate to drive the first air outlet grille to rotate.

[0024] In this way, the rigid meshing of the gears and the gear disc enables a 1:1 power transmission, ensuring that the rotation angle of the first air outlet grille strictly corresponds to the output angle of the first motor, avoiding air outlet direction deviation caused by transmission errors. The concentric nesting of the double annular frames and the unique axis of rotation prevent eccentric wobbling when the first air outlet grille rotates. Combined with the continuous transmission of the gear meshing, it can significantly reduce vibration and noise during rotation, improving the quietness of product operation.

[0025] This application also provides an air conditioner, wherein the transmission component is configured such that when the second motor rotates and the first air outlet grille stops, the transmission component can drive the air guide plate to swing.

[0026] Thus, when the first motor stops, the first air outlet grille remains stationary, while the output end of the second motor rotates around its own axis. The input end of the transmission component is connected to the output end of the second motor, obtaining active rotational power to drive the air guide plate to swing around the second axis. At this time, the swing of the air guide plate is determined only by the speed of the second motor, realizing that the first air outlet grille remains stationary while the air guide plate adjusts the airflow independently.

[0027] When the angular velocity of the first air outlet grille is the same as that of the second motor, the air guide plate rotates with the first air outlet grille and does not swing.

[0028] Thus, when the angular velocity of the first air outlet grille is the same as that of the second motor, there is no relative angular velocity between them, meaning their movements are completely synchronized. The transmission components do not rotate relative to each other, and the motion cannot be converted into the oscillating power of the air guide plate. At this time, the air guide plate simply follows the first air outlet grille in rotation without any additional oscillation, achieving overall macroscopic airflow adjustment driven by the first air outlet grille and the air guide plate.

[0029] When the first air outlet grille rotates and the second motor stops, the transmission assembly can drive the air deflector to swing.

[0030] Thus, when the first motor drives the first air outlet grille to rotate, the air deflector is synchronously passively rotated with the first air outlet grille, the second motor stops, and the input end of the transmission assembly has no active rotating power. Since the air deflector rotates with the first air outlet grille and the input end of the transmission assembly is fixed, the two form opposite angular velocities. The transmission assembly converts the relative motion generated by the passive rotation of the air deflector into swinging of the air deflector around the second axis, thereby realizing the function of synchronous air adjustment of the air deflector when the first air outlet grille rotates.

[0031] Compared with the prior art, the application has the following beneficial effects: In the application, the second motor of the second driving assembly is fixed to the fixed support. Since the rotating axis of the second motor is parallel to the first axis, the relative position between the second motor and the first air outlet grille only has coaxial rotation without radial deviation when the first air outlet grille rotates, thereby providing a stable motion reference for the transmission assembly. The transmission assembly is connected between the output end of the second motor and one of the air deflectors. Specifically, the first transmission part is connected to the output end of the second motor, one end of the second transmission part is connected to the first transmission part, and the other end of the second transmission part is connected to at least one of the air deflectors. When the first transmission part rotates relative to the first air outlet grille, at least part of the second transmission part can move radially along the first air outlet grille to drive the air deflectors to rotate around the second axis, thereby driving all the air deflectors to swing synchronously through the linkage structure of the air deflectors, and realizing fine air adjustment.

[0032] Thus, the second motor and the wire or other connecting components supplied with power from the outside do not need to reciprocate with the moving components, thereby avoiding that the wire frequently bears tensile stress and torsional stress, and fundamentally eliminating the problems of wire winding, bending and breaking. The second motor itself does not participate in the rotating motion, and there is no risk of loose or failed connection of components caused by reciprocating rotation, thereby ensuring long-term stable operation of the driving assembly.

[0033] Moreover, the first motor drives the first air outlet grille to rotate, which can quickly realize macro adjustment of the air outlet direction, such as large-range left-right air sweeping. The second motor drives the air deflectors to swing through the transmission assembly, and the air adjustment action is independent of the rotation of the first air outlet grille, that is, the second transmission part can drive the air deflectors to swing when the first transmission part rotates relative to the first air outlet grille. When the first air outlet grille drives the air deflectors to rotate by a large angle, the air deflectors can swing up and down synchronously, thereby realizing fine requirements such as fixed-point air supply and soft air diffusion, and improving the user's sense of comfort.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0039] In addition, the above-mentioned part of the terms may be used to represent other meanings in addition to the orientation or positional relationship, for example, the term "upper" may also be used to represent a certain dependent relationship or connection relationship in some cases. Those of ordinary skill in the art can understand the specific meaning of these terms in the present application according to the specific situation.

[0040] In addition, the terms "mount", "set", "provided with", "connect", "connected" should be broadly understood. For example, it can be fixed connection, detachable connection, or integral structure; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or internal communication between two devices, elements or components.

Unless otherwise stated, the meaning of "multiple" is two or more.

[0042] Before explaining the technical solutions of the present application, the background art of the present application is explained.

[0043] In the related art, when the cabinet machine starts the air adjusting function, the air outlet grille needs to rotate back and forth within a preset angle range to preliminarily change the air outlet direction of the air outlet, and the air deflector installed on the air outlet grille also rotates synchronously. On this basis, in order to further finely adjust the air outlet direction, a driving member is usually arranged at the rotation axis of the air outlet grille, which can drive the air deflector to swing around its own swing axis.

[0044] However, with the continuous rotation of the air outlet grille, the wires connected to the above driving member need to frequently bear tensile stress and torsional stress, which is easy to be entangled or bent; at the same time, other components of the driving member may also appear connection failure due to long-term reciprocating rotation. Among them, if the entanglement or bending of the wire is accumulated for a long time, it will cause the wire to break, and then the driving member driving the air deflector to swing cannot obtain electric energy, eventually causing the function of the air deflector to finely adjust the air outlet direction to fail.

[0045] Based on this, the embodiments of the present application provide an air conditioner which can avoid the problems of wire entanglement, bending, breaking and the like of the motor, and avoid the risk of loose or failure connection of other connecting components on the motor.

[0046] The specific embodiments and drawings of the present application will be described below. Figure 1 to the drawings Figure 15 The technical solutions of the air conditioner of the present application are described.

[0047] As Figure 1 An embodiment of the present application provides an air conditioner, which comprises a cabinet machine 100. The cabinet machine 100 is a floor type indoor unit of a split type air conditioner, which is usually placed on the indoor floor, and the compressor and other refrigeration equipment are located in the outdoor unit, which are connected and work through pipes and lines.

[0048] As shown in Figure 1 , the cabinet machine 100 can include a cabinet 10, and the cabinet 10 is provided with an air outlet 11, which is an outlet for the air conditioner to deliver the processed cold and hot air to the indoor, and the size, shape and position of the air outlet 11 will affect the air outlet effect and indoor air circulation of the air conditioner.

[0049] As shown in Figure 2 and Figure 3 , the cabinet machine 100 can further include a fixed support 20, which is fixedly arranged on the cabinet 10 and located at the air outlet 11.

[0050] As shown in Figure 3 , the cabinet machine 100 can further include a first air outlet grille 30, which is rotatably installed on the fixed support 20 around a first axis and can rotate relative to the fixed support 20. Its function is to adjust the direction and angle of the air outlet, and also plays a certain decorative and protective role for the air outlet 11.

[0051] As shown in Figures 3 to 5 , the cabinet machine 100 can further include a plurality of air deflectors 40, which are arranged along a second axis and rotatably installed on the first air outlet grille 30 around the second axis. The plurality of air deflectors 40 are drivingly connected, and when the first air outlet grille 30 rotates relative to the fixed support 20, the first air outlet grille 30 can drive the plurality of air deflectors 40 to rotate to change the air outlet angle of the air outlet 11. The first axis is perpendicular to the second axis.

[0052] As shown in Figure 3 and Figure 4 , the cabinet machine 100 can further include a first drive assembly 50 for driving the first air outlet grille 30 to rotate, and the first drive assembly 50 includes a first motor 51 fixed to the fixed support 20.

[0053] Among them, the reciprocating rotation of the first air outlet grille 30 is limited within a preset angle, which can be selected according to actual use, for example, 30°, 90°, 180°, etc. It should be noted that the reciprocating rotation of the first air outlet grille 30 within the preset angle is based on the intermittent adjustment of the user, rather than continuous rotation during the operation of the cabinet machine 100.

[0054] It should be explained that since the first motor 51 is fixed on the fixed support 20 and does not need to rotate with the first air outlet grille 30, the motor wire of the first motor 51 does not have the risk of wire entanglement.

[0055] As shown in Figures 3 to 5As shown, the cabinet machine 100 can further include a second driving assembly 60, which is capable of driving one of the air deflectors 40 to swing around a second axis, and capable of individually controlling the swing angle of the air deflector 40, to further refine the adjustment of the air outlet direction.

[0056] As shown, the second driving assembly 60 includes a second motor 61 fixed to the fixed support 20, and the rotation axis of the second motor 61 is parallel to the first axis. The second motor 61 provides power for the swing of the air deflector 40, and drives the air deflector 40 to swing around the shaft through the rotation of the second motor 61, to realize accurate control of the air outlet direction. Figure 4 As shown, the second driving assembly 60 further includes a transmission assembly 62 connected between the second motor 61 and the air deflector 40, as shown, the transmission assembly 62 includes a first transmission part 620 and a second transmission part 621, the first transmission part 620 is rotationally connected with the output end of the second motor 61, and is configured to be rotatable around the rotation axis of the second motor 61.

[0057] Figure 4 As shown, the second transmission part 621 is connected to the first transmission part 620 at one end, and is connected to at least one of the plurality of air deflectors 40 at the other end, and is configured to move at least a part of the second transmission part 621 along the radial direction of the first air outlet grille 30 when the first transmission part 620 rotates relative to the first air outlet grille 30, to drive the plurality of air deflectors 40 to rotate around the second axis. Figure 5 Figure 6 Among them, the X direction in the figure is the direction of the second axis; the Y direction is the radial direction of the first air outlet grille 30, that is, the sliding direction of the sliding block 623; and the M direction is the direction of the first axis, that is, the direction of the rotation axis of the second motor 61.

[0058] In this way, the second motor 61 of the second driving assembly 60 is fixed to the fixed support 20, and since the rotation axis of the second motor 61 is parallel to the first axis, it is ensured that when the first air outlet grille 30 rotates, the relative position between the second motor 61 and the first air outlet grille 30 only exists coaxial rotation, without radial deviation, to provide a stable motion reference for the transmission assembly 62.

[0059]

[0060]

[0061] ​​​​Further, the transmission assembly 62 is connected between the output end of the second motor 61 and one of the air deflectors 40, the first transmission part 620 is connected with the output end of the second motor 61, one end of the second transmission part 621 is connected with the first transmission part 620, and the other end of the second transmission part 621 is connected with at least one of the air deflectors 40, when the first transmission part 620 rotates relative to the first air outlet grille 30, at least part of the second transmission part 621 can move along the radial direction of the first air outlet grille 30 to drive the air deflectors 40 to rotate around the second axis, and then drive all the air deflectors 40 to swing synchronously through the linkage structure of the air deflectors 40, so as to realize fine air adjustment.

[0062] Therefore, the second motor 61 does not need to reciprocate with the moving part, and the wire or other connecting part supplied by the external power supply does not need to reciprocate, so as to avoid that the wire frequently bears tensile stress and torsional stress, and to fundamentally eliminate the problems of wire winding, bending and breaking. The second motor 61 itself does not participate in the rotation, and there is no risk of loose connection or failure of the part caused by reciprocating rotation, so as to ensure long-term stable operation of the driving assembly.

[0063] Further, the first motor 51 drives the first air outlet grille 30 to rotate, so as to quickly realize macro adjustment of the air outlet direction, for example, large-range air sweeping left and right, and the second motor 61 drives the air deflectors 40 to swing through the transmission assembly 62, and the air adjustment action is independent of the rotation of the first air outlet grille 30, that is, when the first transmission part 620 of the transmission assembly 62 rotates relative to the first air outlet grille 30, the second transmission part 621 can drive the air deflectors 40 to swing, so as to realize that when the first air outlet grille 30 drives the air deflectors 40 to rotate by a large angle, the air deflectors 40 can swing up and down synchronously, so as to realize fine requirements such as fixed-point air supply and soft air diffusion, and to improve the user's sense of comfort.

[0064] The rotation of the first transmission part 620 relative to the first air outlet grille 30 can be the rotation of one of them or different angular velocities of the rotation, which is not limited in the application.

[0065] In some embodiments, as shown in Figures 6 to 10 The first transmission part 620 includes a rotating handle 6201, the second transmission part 621 includes a first connecting rod 622, a sliding block 623 and a second connecting rod 624 which are sequentially and transmissionally connected, and the rotating handle 6201 is fixedly connected with the output shaft of the second motor 61. The first end of the first connecting rod 622 is rotationally connected with the rotating handle 6201, and the second end of the first connecting rod 622 is rotationally connected with the sliding block 623. The sliding block 623 is arranged to slide relative to the second motor 61 along the radial direction of the first air outlet grille 30, and the radial direction of the first air outlet grille 30 is perpendicular to the rotation axis direction of the second motor 61. The first end of the second connecting rod 624 is rotationally connected with the sliding block 623, and the plurality of air deflectors 40 includes a first air deflector 41. The second end of the second connecting rod 624 is rotationally connected with the first air deflector 41.

[0066] In this way, the rotating handle 6201 serves as a power input end and is fixedly connected with the output shaft of the second motor 61. When the second motor 61 rotates, the rotating handle 6201 is driven to rotate synchronously around the rotation axis of the second motor 61, so as to convert the rotating power of the second motor 61 into eccentric circular motion. The end point of the rotating handle 6201 performs circular motion around the axis of the second motor 61. The first connecting rod 622 serves as a motion transmission medium. The first end is rotationally connected with the rotating handle 6201, and the second end is rotationally connected with the sliding block 623. The eccentric circular motion of the rotating handle 6201 is converted into linear reciprocating motion of the sliding block 623. When the rotating handle 6201 rotates, the circular track of the end point thereof drives the sliding block 623 to slide along the radial direction of the first air outlet grille 30 through the pushing and pulling of the first connecting rod 622.

[0067] The sliding block 623 is arranged to slide along the radial direction of the first air outlet grille 30 relative to the second motor 61. After receiving the linear power transmitted by the first connecting rod 622, the sliding block 623 performs reciprocating sliding along the radial direction of the first air outlet grille 30 and simultaneously transmits the linear motion to the second connecting rod 624. The second connecting rod 624 serves as a power output end. The first end is rotationally connected with the sliding block 623, and the second end is rotationally connected with the first air deflector 41. The linear reciprocating motion of the sliding block 623 is converted into reciprocating swinging of the first air deflector 41 around the second axis, i.e., the swinging axis of the air deflector 40 itself. Then, all the air deflectors 40 are driven to swing synchronously through the linkage structure between the air deflectors 40.

[0068] Therefore, the rigid connecting rod is used in cooperation with the sliding block 623. In the transmission process, there is no elastic deformation. The rotating angle of the output end of the second motor 61 can be accurately converted into the swinging angle of the air deflector 40. For example, when the second motor 61 rotates by 180°, the sliding block 623 slides by a preset distance, and the air deflector 40 swings by 15°. The swinging angle of the air deflector 40 is controllable and stable, the outflow direction is prevented from deviating or being disordered, and the precision of fine air regulation is improved.

[0069] The first transmission part 620 includes the rotating handle 6201, and the second transmission part 621 includes the first connecting rod 622, the sliding block 623 and the second connecting rod 624 which are sequentially and transmissionally connected. There is no complex element, the number of parts is small, the assembly difficulty is low, and the risk of failure caused by cooperation of multiple parts is reduced. The rigid mechanical structure has strong anti-aging and anti-wear abilities and can withstand fatigue loads of reciprocating motion for a long time. Transmission failure caused by aging of parts is avoided, and the service life is prolonged.

[0070] In some embodiments, as Figures 11 to 15As shown, the middle part of the first air outlet grille 30 is provided with a mounting shell 31, the mounting shell 31 is provided with a avoiding port 32 towards the direction of the first air deflector 41, the transmission assembly 62 extends to the first air deflector 41 from the mounting shell 31 through the avoiding port 32, the side wall of the avoiding port 32 is provided with a guide groove 321 along the radial direction of the first air outlet grille 30, and the sliding block 623 is in sliding connection with the guide groove 321.

[0071] In this way, the guide groove 321 restricts the lateral deviation or rotation of the sliding block 623, and ensures that the sliding block 623 always moves linearly along the radial direction of the first air outlet grille 30, thereby avoiding the first connecting rod 622 and the second connecting rod 624 from generating additional torque due to the deviation of the sliding block 623, and preventing the swing angle deviation of the air deflector 40 or the transmission jam.

[0072] The mounting shell 31 accommodates the transmission components such as the rotating handle 6201, the first connecting rod 622 and the sliding block 623, and only exposes the connecting end of the second connecting rod 624, thereby avoiding dust and condensed water from directly adhering to the transmission components, preventing the transmission resistance from increasing or jamming due to rust and dust accumulation of the components, avoiding the user from accidentally touching or colliding with the transmission components during maintenance, reducing the risk of interference with other structures during the rotation of the grille, and protecting the integrity of the transmission system.

[0073] In some embodiments, as shown, Figure 9 The first end of the first connecting rod 622 is provided with a first rotating groove 6221, the end of the rotating handle 6201 close to the first connecting rod 622 is provided with a first rotating part 6202, the first rotating part 6202 extends into the first rotating groove 6221 and is in rotating connection with the first rotating groove 6221, and the rotating axis of the first rotating part 6202 is parallel to the rotating axis of the second motor 61. The second end of the first connecting rod 622 is provided with a second rotating groove 6222, and the end of the sliding block 623 close to the first connecting rod 622 is provided with a second rotating part 6231, the second rotating part 6231 extends into the second rotating groove 6222 and is in rotating connection with the second rotating groove 6222, and the rotating axis of the second rotating part 6231 is parallel to the rotating axis of the second motor 61.

[0074] In this way, the first end of the first connecting rod 622 is provided with the first rotating groove 6221 for accommodating the first rotating part 6202 of the rotating handle 6201, the first rotating part 6202 is matched with the inner wall of the first rotating groove 6221 and can be completely inserted into the groove to form an embedded fit, and the rotating axis of the first rotating part 6202 is parallel to the rotating axis of the second motor 61.

[0075] When the second motor 61 drives the rotating handle 6201 to rotate around its own axis, the first rotating part 6202 moves in a circle with the rotating handle 6201, and slides and rotates in the first rotating groove 6221. Due to the limiting effect of the first rotating groove 6221 on the first rotating part 6202, the circular motion of the rotating handle 6201 is converted into a push-pull force on the first connecting rod 622, which drives the first connecting rod 622 to swing and provides power for the linear motion of the slider 623. The second rotating groove 6222 is matched with the second rotating part 6231.

[0076] Therefore, the design that the rotating part rotates in the rotating groove allows the first connecting rod 622 to flexibly adjust the angle with the rotating handle 6201 and the slider 623 during the swinging process. For example, when the rotating handle 6201 rotates to the highest point, the included angle between the first connecting rod 622 and the rotating handle 6201 increases, and the first rotating part 6202 can rotate synchronously in the first rotating groove 6221 to adapt to the angle, avoiding the jam caused by rigid connection. Similarly, the connection between the first connecting rod 622 and the slider 623 can also adapt the swinging angle through the rotation of the second rotating part 6231, ensuring smooth transmission without resistance.

[0077] The axes of all rotating parts are parallel to the motor axis, so that the motion of the transmission assembly 62 is concentrated in the same vertical plane, there is no spatial cross motion, and component collision or interference caused by axis misalignment is completely avoided, further reducing the risk of transmission failure. The embedded rotating groove limits the rotation of the rotating part in the horizontal direction and only allows the rotating part to rotate around the axis, ensuring that the power of the first connecting rod 622 can be accurately transmitted to the slider 623, avoiding power loss or motion deviation caused by loose connection.

[0078] The first rotating groove 6221 and the second rotating groove 6222 can be circular grooves, U-shaped grooves, arc grooves, etc., and the first rotating part 6202 and the second rotating part 6231 can be cylindrical protruding shafts, hemispherical protrusions, etc., which are not limited in the present application.

[0079] In some embodiments, as shown in Figure 9 The first end of the second connecting rod 624 is sleeved on the first rotating arm 6232 and rotationally connected with the first rotating arm 6232, and the extension direction of the first rotating arm 6232 is perpendicular to the rotation axis direction of the second motor 61 and the radial direction of the first air outlet grille 30. As shown in Figure 7 The second end of the second connecting rod 624 is sleeved on the second rotating arm 411 and rotationally connected with the second rotating arm 411, and the extension direction of the second rotating arm 411 is perpendicular to the rotation axis direction of the second motor 61 and the radial direction of the first air outlet grille 30.

[0080] Thus, the connection of the second connecting rod 624 with the slider 623 and the first air deflector 41 is all rigid fitting with shaft sleeve, without transmission gap, the linear motion of the slider 623 can be directly converted into the swing torque of the air deflector 40 through the second connecting rod 624, with high power transmission efficiency; the extension direction of the rotating arm and the swing direction of the first air deflector 41 form an optimal moment transmission angle, and the slight swing of the second connecting rod 624 can drive the air deflector 40 to quickly respond, avoiding swing delay caused by power loss and improving the air conditioning response speed.

[0081] The shaft sleeve connection has a large contact area, which can disperse the force in the transmission process and avoid local stress concentration, and the connection has high fault tolerance to the assembly position, the sleeve of the second connecting rod 624 only needs to be sleeved into the rotating arm to complete the assembly, without the need for precise alignment of the hole position, reducing the assembly difficulty and precision requirement of the production line, with strong adaptability, facilitating mass production and model iteration.

[0082] In some embodiments, as shown in Figure 5 , a plurality of air deflectors 40 are connected in transmission through a third connecting rod 42, so that the plurality of air deflectors 40 swing synchronously.

[0083] Thus, the third connecting rod 42 is connected to the first air deflector 41 and the remaining air deflectors 40 as a bridge, and the swing power of the first air deflector 41 is synchronously transmitted to all air deflectors 40, and since the third connecting rod 42 is a rigid or low-deformation component, it will not produce obvious displacement deviation when transmitting power, ensuring that the swing angle, swing speed and swing phase of all air deflectors 40 are completely consistent, avoiding the problem of swing lag or angle deviation of part of the air deflectors 40.

[0084] The third connecting rod 42 is provided with a rotating pair at the connection with each air deflector 40, ensuring that the air deflector 40 can swing flexibly around its own rotating shaft, and the third connecting rod 42 only transmits swing power without interfering with the rotating freedom of the air deflector 40.

[0085] The plurality of air deflectors 40 extend in the same direction and are uniformly arranged, the third connecting rod 42 is designed in a long strip shape parallel to the arrangement direction of the air deflectors 40, and the spacing of each connection point is consistent with the arrangement spacing of the air deflectors 40, ensuring that the third connecting rod 42 can synchronously pull or push all air deflectors 40 in a straight line direction after connection, avoiding transmission jamming caused by misalignment of the connection points.

[0086] In some embodiments, as shown in Figure 4 and Figure 11 , the fixed support 20 includes a first annular frame 21 and a connecting arm 22, the connecting arm 22 is bridged on the first annular frame 21, and the second motor 61 is fixed on the connecting arm 22.

[0087] Thus, the annular structure of the first annular frame 21 can effectively resist the radial force generated when the first air outlet grille 30 rotates, such as the centrifugal force when the first air outlet grille 30 rotates, and the friction with the fixed support 20, to avoid distortion or deviation of the frame body after long-term use, and ensure smooth rotation of the grille.

[0088] The connecting arm 22 is connected across the opposite sides of the first annular frame 21 to form a simply supported beam structure. When the second motor 61 is fixed in the middle, the weight of the motor and the reaction force during operation can be transmitted to the first annular frame 21 through both ends, dispersing the local stress and avoiding bending deformation of the connecting arm 22 due to excessive cantilever stress, to ensure stable position of the second motor 61.

[0089] In some embodiments, as shown in Figure 4 and Figure 12 , the first air outlet grille 30 includes a second annular frame 33 located inside the first annular frame 21, and the second annular frame 33 is provided with a toothed disc 331. As shown in Figure 4 , the first motor 51 is fixed to the first annular frame 21, and the output end of the first motor 51 is provided with a gear 511 engaged with the toothed disc 331 to drive the first air outlet grille 30 to rotate.

[0090] Thus, the rigid engagement of the gear 511 and the toothed disc 331 can achieve 1:1 transmission of power, ensuring that the rotation angle of the first air outlet grille 30 strictly corresponds to the output angle of the first motor 51, and avoiding deviation of the air outlet direction caused by transmission error. The double annular frames are concentrically nested, with a unique rotation axis, so that the first air outlet grille 30 does not produce eccentric shaking when rotating, and the continuous transmission of the gear 511 engagement can significantly reduce vibration and noise during rotation, improving the quietness of product operation.

[0091] In some embodiments, as shown in Figure 4 , the transmission assembly 62 is configured to drive the air deflector 40 to swing when the second motor 61 rotates and the first air outlet grille 30 stops.

[0092] When the angular velocity of the first air outlet grille 30 and the angular velocity of the second motor 61 are the same, the air deflector 40 rotates with the first air outlet grille 30, and the air deflector 40 does not swing; When the first air outlet grille 30 rotates and the second motor 61 stops, the transmission assembly 62 can drive the air deflector 40 to swing.

[0093] Thus, the three working conditions correspond to three air conditioning modes, which can be flexibly switched according to the user's use scene, solving the problem of single air conditioning function of traditional air conditioning.

[0094] When the first motor 51 stops, the first air outlet grille 30 remains stationary, and the output end of the second motor 61 rotates around its own axis. The input end of the transmission component 62 is connected to the output end of the second motor 61, obtaining active rotational power to drive the air guide plate 40 to swing around the second axis. At this time, the swing of the air guide plate 40 is determined only by the speed of the second motor 61, realizing that the first air outlet grille 30 remains stationary while the air guide plate 40 adjusts the airflow independently.

[0095] When the angular velocity of the first air outlet grille 30 is the same as that of the second motor 61, there is no relative angular velocity between them, meaning their movements are completely synchronized. The transmission component 62 does not rotate relative to the first air outlet grille 30, and therefore cannot convert the motion into the oscillating power of the guide vane 40. At this time, the guide vane 40 simply follows the first air outlet grille 30 in rotation, without any additional oscillation, thus achieving overall macroscopic airflow adjustment driven by the first air outlet grille 30 and the guide vane 40.

[0096] When the first motor 51 drives the first air outlet grille 30 to rotate, the air guide plate 40 rotates passively and synchronously with the first air outlet grille 30. The second motor 61 stops, and its output end remains stationary. The input end of the transmission component 62 has no active rotational power. Since the air guide plate 40 rotates with the first air outlet grille 30, while the input end of the transmission component 62 is fixed, the two form opposite relative angular velocities. The transmission component 62 converts this relative motion generated by the passive rotation of the air guide plate 40 into the oscillation of the air guide plate 40 around the second axis, realizing the function of synchronous air adjustment of the air guide plate 40 when the first air outlet grille 30 rotates.

[0097] In some embodiments, such as Figure 1 As shown, the cabinet unit 100 also includes a fresh air module, a humidification module, and a second air outlet grille 12. The fresh air module includes a fresh air outlet, and the humidification module includes a humidification outlet. Both the fresh air outlet and the humidification outlet are located at the second air outlet grille 12. The humidification outlet is located inside the fresh air outlet so that the fresh air from the fresh air outlet can drive the steam from the humidification outlet to blow out of the second air outlet grille 12.

[0098] Thus, the fresh air module is integrated inside the casing 10 of the cabinet unit 100, usually near the side wall or back of the cabinet unit 100, to facilitate the introduction of outdoor fresh air. The fresh air module includes a fresh air inlet for connecting to the outside, as well as a fresh air fan, an air filter unit and a fresh air outlet. The fresh air module drives outdoor air through the fresh air fan to filter the air through the filter screen to form clean fresh air, which is finally delivered to the second air outlet grille 12 area through the fresh air outlet.

[0099] The fresh air outlet and the humidifying outlet of the humidifying module are both arranged in the inner region of the second air outlet grille 12, and the directions of the fresh air outlet and the humidifying outlet are consistent with the air guiding direction of the second air outlet grille 12, so that the air flow can be smoothly sent along the direction of the air guiding grille blades. The clean fresh air discharged from the fresh air outlet and the water vapor discharged from the humidifying outlet are preliminarily mixed in the cavity, and then guided by the air guiding blades of the second air outlet grille 12 to form mixed air with appropriate temperature, standard humidity and sufficient oxygen content, thereby avoiding the discomfort caused by directly blowing single fresh air or single humidified air to the user.

[0100] Since the steam is prone to condense near the humidifying outlet when there is no fresh air to drive, the humidifying outlet is arranged in the fresh air outlet, so that the fresh air of the fresh air outlet can drive the steam of the humidifying outlet to blow out of the second air outlet grille 12. When the positive pressure air flow of the fresh air outlet flows, a negative pressure area is formed inside, the fresh air actively drags the steam of the humidifying outlet to diffuse, the steam and the fresh air are mixed inside the outlet, the diffusion speed is improved, the condensate water around the humidifying outlet is eliminated, and the mold is prevented from breeding.

[0101] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
