Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, 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 arranged at the rotation 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:

[0007] a cabinet machine, comprising:

[0008] a cabinet, wherein an air outlet is arranged on the cabinet;

[0009] a fixed support, which is fixedly arranged on the cabinet and located at the air outlet;

[0010] a first air outlet grille, which is rotatably arranged on the fixed support around a first axis;

[0011] a plurality of air deflectors, which are arranged along a second axis and rotatably arranged on the first air outlet grille around the second axis, and are transmissionally 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.

[0012] The first driving assembly is configured to drive the first air outlet grille to rotate, and the first driving assembly comprises:

[0013] The first motor is fixed to the fixed support.

[0014] The second driving assembly is configured to drive one of the air deflectors to oscillate about the second axis, and the second driving assembly comprises:

[0015] The second motor is fixed to the fixed support, and the rotation axis of the second motor is parallel to the first axis.

[0016] The transmission assembly is connected between the second motor and the air deflectors, and the transmission assembly comprises:

[0017] The first transmission part is connected to the output shaft of the second motor and is configured to rotate about the rotation axis of the second motor.

[0018] The second transmission part is connected at one end to the first transmission part and at the other end to at least one of the air deflectors, and the second transmission part is configured to move at least a part of the second transmission part radially along 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 about the second axis.

[0019] In this way, the second motor does not need to reciprocate and rotate with the moving part and other connecting components powered by the external power supply, thereby avoiding the problems of wire entanglement, bending and breakage caused by the wire frequently bearing tensile stress and torsional stress.

[0020] In addition, the first motor drives the first air outlet grille to rotate, so that macroscopic adjustment of the air outlet direction can be quickly realized, such as large-scale left-right air sweeping.

[0021] The first transmission part comprises a rotating handle fixedly connected to the output shaft of the second motor.

[0022] The second transmission part comprises a first connecting rod, a sliding block and a second connecting rod connected in sequence, a first end of the first connecting rod is rotationally connected with the rotating handle, and a second end of the first connecting rod is rotationally connected with the sliding block.

[0023] The sliding block is arranged to slide relative to the second motor in the radial direction of the first air outlet grille, and the radial direction of the first air outlet grille is perpendicular to the rotation axis direction of the second motor.

[0024] A first end of the second connecting rod is rotationally connected with the sliding block, a plurality of air deflectors comprise a first air deflector, and a second end of the second connecting rod is rotationally connected with the first air deflector.

[0025] In this way, the rigid connecting rod is matched with the sliding block, there is no elastic deformation in the transmission process, the output end rotation angle of the second motor can be accurately converted into the swing angle of the air deflector, for example, the output end of the second motor rotates by 180°, the sliding block slides by a preset distance, and the air deflector swings by 15°, so that the swing angle of the air deflector is controllable and stable, the outflow direction is prevented from deviating or being disordered, and the precision of fine air regulation is improved.

[0026] The first transmission part comprises a rotating handle, the first connecting rod, the sliding block and the second connecting rod of the second transmission part, there are no complex elements, the number of parts is small, the assembly difficulty is low, and the risk of failure of multi-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.

[0027] The application also provides an air conditioner, a 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 air deflector, the transmission assembly extends to the first air deflector through the avoiding opening in the mounting shell, a 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.

[0028] In this way, the guide groove restricts the lateral deviation or rotation of the sliding block, the guide groove ensures that the sliding block always moves linearly in the radial direction of the first air outlet grille, the first connecting rod and the second connecting rod are prevented from generating additional torque due to deviation of the sliding block, and the swing angle deviation or transmission jam of the air deflector is prevented.

[0029] The mounting shell accommodates 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 jamming caused by rust and dust accumulation of the components is prevented, the transmission components are prevented from being accidentally touched or collided during maintenance, the risk of interference with other structures during rotation of the grille is reduced, and the integrity of the transmission system is protected.

[0030] The application also provides an air conditioner, the first end of the first connecting rod is provided with a first rotating groove, the end of the rotating handle close to the first connecting rod is provided with a first rotating part, the first rotating part extends into the first rotating groove and is rotationally connected with the first rotating groove, and the rotating axis of the first rotating part is parallel to the rotating axis of the second motor.

[0031] The second end of the first connecting rod is provided with a second rotating groove, the end of the sliding block close to the first connecting rod is provided with a second rotating part, the second rotating part 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.

[0032] 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 that the whole transmission process is smooth and free of resistance.

[0033] The application also provides an air conditioner, the end of the sliding block close to the second connecting rod is also 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 direction of the rotating axis of the second motor and the radial direction of the first air outlet grille.

[0034] 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 direction of the rotating axis of the second motor and the radial direction of the first air outlet grille.

[0035] 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, 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.

[0036] The application also provides an air conditioner, a plurality of air deflectors are transmissionally connected through a third connecting rod, so that the plurality of air deflectors swing synchronously.

[0037] Thus, the third connecting rod is connected with the first deflector and the remaining deflectors as a bridge, and synchronously transmits the swing power of the first deflector to all the deflectors. Since the third connecting rod is a rigid or low-deformation component, no obvious displacement deviation is generated when the power is transmitted, ensuring that the swing angle, swing speed and swing phase of all the deflectors are completely consistent, and avoiding the problem of swing lag or angle deviation of part of the deflectors.

[0038] The application also provides an air conditioner, and the fixed support comprises:

[0039] The first annular frame;

[0040] The connecting arm is connected across the first annular frame, and the second motor is fixed on the connecting arm.

[0041] Thus, the annular structure of the first annular frame can effectively resist the radial force generated when the first air outlet grille rotates, such as the centrifugal force when the first air outlet grille rotates and the friction with the fixed support, so as to avoid the distortion or deviation of the frame body after long-term use and ensure smooth rotation of the grille.

[0042] The application also provides an air conditioner, and the first air outlet grille comprises a second annular frame located in the first annular frame, and the second annular frame is provided with a toothed disc.

[0043] The first motor is fixed on the first annular frame, the output end of the first motor is provided with a gear, and the gear is in meshing connection with the toothed disc to drive the first air outlet grille to rotate.

[0044] Thus, the rigid meshing of the gear and the toothed disc can achieve 1:1 transmission of power, ensure that the rotation angle of the first air outlet grille strictly corresponds to the output angle of the first motor, and avoid the deviation of the air outlet direction caused by transmission error. The double annular frames are concentrically nested, the rotation axis is unique, and the first air outlet grille will not produce eccentric shaking when rotating, and the continuous transmission of the gear meshing can significantly reduce the vibration noise in the rotation process and improve the quietness of product operation.

[0045] The application also provides an air conditioner, and the transmission assembly is configured to drive the deflectors to swing when the second motor rotates and the first air outlet grille stops.

[0046] Thus, when the first motor stops and the first air outlet grille is fixed, the output end of the second motor rotates around its own axis, the input end of the transmission assembly is connected with the output end of the second motor, and the active rotary power is obtained to drive the deflectors to swing around the second axis. At this time, the swing of the deflectors is only determined by the rotating speed of the second motor, realizing that the first air outlet grille is stationary and the deflectors are individually adjusted.

[0047] When the angular velocity of the rotation of the first air outlet grille is the same as the angular velocity of the rotation of the second motor, the air deflector rotates with the first air outlet grille and does not swing.

[0048] Thus, when the angular velocity of the rotation of the first air outlet grille is the same as the angular velocity of the rotation of the second motor, there is no relative angular velocity between the two, that is, the two movements are completely synchronized, the transmission assembly has no relative rotation, and cannot convert the movement into swing power of the air deflector. At this time, the air deflector only rotates with the first air outlet grille, without additional swinging, realizing the whole macroscopic air conditioning of the air deflector driven by the first air outlet grille.

[0049] When the first air outlet grille rotates and the second motor stops, the transmission assembly can drive the air deflector to swing.

[0050] Thus, when the first motor drives the first air outlet grille to rotate, the air deflector is passively rotated synchronously with the first air outlet grille, and the second motor stops, and the output end is fixed. The input end of the transmission assembly has no active rotation 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 a reverse relative angular velocity. The transmission assembly converts the relative movement of the air deflector caused by passive rotation into swinging of the air deflector around the second axis, realizing the function of synchronous air conditioning of the air deflector when the first air outlet grille rotates.

[0051] Compared with the prior art, the application has the following beneficial effects:

[0052] In the application, the second motor of the second driving assembly is fixed to the fixed support. Since the rotation axis of the second motor is parallel to the first axis, it is ensured that the relative position of the second motor and the first air outlet grille only has coaxial rotation when the first air outlet grille rotates, without radial deviation, thereby providing a stable movement 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 plurality of air deflectors. When the first transmission part rotates relative to the first air outlet grille, at least a part of the second transmission part can move radially along the first air outlet grille to drive the plurality of 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, realizing fine air conditioning.

[0053] Therefore, 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, avoiding the wire from frequently bearing 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 movement, 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.

[0054] Moreover, the first motor drives the first air outlet grille to rotate, so that macro adjustment of the air outlet direction can be quickly realized, for example, large-range air sweeping left and right; the second motor drives the air deflector to swing through the transmission assembly, and the air deflection 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 deflector to swing, so that when the first air outlet grille drives the air deflector to rotate by a large angle, the air deflector can swing up and down synchronously to realize fine requirements such as fixed-point air supply and soft air diffusion, and the user's sense of comfort is improved.

[0079] ​​With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application.

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

[0081] In addition, in addition to indicating the orientation or positional relationship, the above-mentioned partial terms may also be used to indicate other meanings, for example, the term "upper" may also be used to indicate a certain dependent relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meaning of these terms in the present application can be understood according to the specific situation.

[0082] In addition, the terms "mount", "set", "provided with", "connected", "connected" should be broadly understood. For example, it can be fixedly connected, detachably connected, or integrally constructed; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or internal communication between two devices, elements or components. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific situation.

[0083] In addition, the terms "first", "second" and the like are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not intended to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of "multiple" is two or more.

[0084] Before the technical solutions of the present application are explained, the background art of the present application is described.

[0085] In the related art, when the cabinet 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 rotation axis of the air outlet grille, which can drive the air deflector to swing around its own swing axis.

[0086] However, as the air outlet grille continues to rotate, the connecting wire of the above-mentioned driving member needs to bear frequent tensile stress and torsional stress, and is prone to winding or bending; 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 winding or bending of the wire is accumulated for a long time, the wire will be broken, and then the driving member driving the air deflector to swing cannot obtain electric energy, and finally the function of fine adjustment of the air deflector to the air outlet direction is lost.

[0087] Based on this, the embodiment of the application provides an air conditioner which can avoid the problems of winding, bending and breaking of the motor wire, and the risk of loose or failure connection of other connecting components on the motor.

[0088] The specific embodiments and drawings will be described below. Figure 1 to the drawings Figure 15 The technical scheme of the air conditioner of the application will be described.

[0089] As shown in Figure 1 , an embodiment of the 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 by pipes and lines to work.

[0090] As shown in Figure 1 , the cabinet machine 100 can comprise a machine shell 10, and the machine shell 10 is provided with an air outlet 11. The air outlet 11 is an outlet of the air conditioner for delivering the processed cold and hot air to the indoor, and the size, shape and position design of the air outlet 11 will affect the air outlet effect of the air conditioner and the indoor air circulation.

[0091] As shown in Figure 2 and Figure 3 , the cabinet machine 100 can further comprise a fixed support 20, which is fixedly arranged on the machine shell 10 and located at the air outlet 11.

[0092] As shown in Figure 3 , the cabinet machine 100 can further comprise a first air outlet grille 30, which is rotatably installed on the fixed support 20 about a first axis, and can rotate relative to the fixed support 20. The first air outlet grille 30 adjusts the direction and angle of the air outlet, and also plays a certain decorative and protective role for the air outlet 11.

[0093] As shown in Figures 3 to 5 , the cabinet machine 100 can further comprise a second air outlet grille 40, which is rotatably installed on the fixed support 20 about a second axis, and can rotate relative to the fixed support 20. The second air outlet grille 40 adjusts the direction and angle of the air outlet, and also plays a certain decorative and protective role for the air outlet 11.As shown in the drawings, the cabinet machine 100 can further include a plurality of air deflectors 40, which are arranged along the second axis and rotatably mounted 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.

[0094] As shown in the drawings, 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. The first drive assembly 50 includes a first motor 51 fixed to the fixed support 20.

[0095] 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 user's intermittent adjustment, rather than continuous rotation during the operation of the cabinet machine 100.

[0096] It should be noted that since the first motor 51 is fixed to 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.

[0097] As shown in the drawings, Figures 3 to 5 The cabinet machine 100 can further include a second drive assembly 60 capable of driving one of the air deflectors 40 to swing around the second axis and capable of individually controlling the swing angle of the air deflectors 40 to further refine the adjustment of the air outlet direction.

[0098] As shown in the drawings, Figure 4 The second drive 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 deflectors 40, and the rotation of the second motor 61 drives the air deflectors 40 to swing around the shaft to achieve precise control of the air outlet direction.

[0099] As shown in the drawings, Figure 4 and Figure 5 The second drive assembly 60 further includes a transmission assembly 62 connected between the second motor 61 and the air deflectors 40, as shown in the drawings, Figure 6 The transmission assembly 62 includes a first transmission part 620 and a second transmission part 621. The first transmission part 620 is rotatably connected to the output end of the second motor 61 and is configured to rotate around the rotation axis of the second motor 61.

[0100] The second transmission part 621 is connected to the first transmission part 620 at one end, and connected to at least one of the plurality of guide vanes 40 at the other end. When the first transmission part 620 rotates relative to the first air outlet grille 30, at least a part of the second transmission part 621 can move in the radial direction of the first air outlet grille 30 to drive the plurality of guide vanes 40 to rotate around the second axis.

[0101] In the figure, the X direction is the direction of the second axis; the Y direction is the radial direction of the first air outlet grille 30, i.e. the sliding direction of the slider 623; and the M direction is the direction of the first axis, i.e. the direction of the rotation axis of the second motor 61.

[0102] In this way, the second motor 61 of the second drive assembly 60 is fixed to the fixed support 20. 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 has coaxial rotation without radial deviation, thereby providing a stable motion reference for the transmission assembly 62.

[0103] Further, the transmission assembly 62 is connected between the output end of the second motor 61 and one of the guide vanes 40. The first transmission part 620 is connected to the output end of the second motor 61, one end of the second transmission part 621 is connected to the first transmission part 620, and the other end of the second transmission part 621 is connected to at least one of the plurality of guide vanes 40. When the first transmission part 620 rotates relative to the first air outlet grille 30, at least a part of the second transmission part 621 can move in the radial direction of the first air outlet grille 30 to drive the plurality of guide vanes 40 to rotate around the second axis, thereby driving all the guide vanes 40 to swing synchronously through the linkage structure of the guide vanes 40, and achieving fine air adjustment.

[0104] In this way, the second motor 61 does not need to reciprocate and rotate with the moving parts and other connecting components supplied with power from the outside, avoiding the problem of wire entanglement, bending and breaking caused by frequent tension and torsion stress of the wire. The second motor 61 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 drive assembly.

[0105] Moreover, the first motor 51 drives the first air outlet grille 30 to rotate, so that macro adjustment of the air outlet direction can be quickly realized, such as large-range air sweeping left and right. The second motor 61 drives the air deflector 40 to swing through the transmission assembly 62, and the air deflection 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 deflector 40 to swing. When the first air outlet grille 30 drives the air deflector 40 to rotate by a large angle, the air deflector 40 can swing up and down synchronously to realize fine requirements such as fixed-point air supply and soft air diffusion, and improve the user's sense of comfort.

[0106] The rotation of the first transmission part 620 relative to the first air outlet grille 30 can be the rotation of one of the two or the difference in angular velocity of the rotation, which is not limited in the application.

[0107] 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 connected in sequence, and the rotating handle 6201 is fixedly connected with the output shaft of the second motor 61.

[0108] 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.

[0109] 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.

[0110] The first end of the second connecting rod 624 is rotationally connected with the sliding block 623, the plurality of air deflectors 40 includes a first air deflector 41, and the second end of the second connecting rod 624 is rotationally connected with the first air deflector 41.

[0111] 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 rotates synchronously around the rotation axis of the second motor 61, converting the rotation of the second motor 61 into eccentric circular motion. The end point of the rotating handle 6201 moves in a circular path around the axis of the second motor 61. The first connecting rod 622 serves as a motion transmission intermediate, with the first end rotationally connected with the rotating handle 6201 and the second end rotationally connected with the sliding block 623. The eccentric circular motion of the rotating handle 6201 is converted into the linear reciprocating motion of the sliding block 623. When the rotating handle 6201 rotates, the circular path of the end point thereof pushes and pulls the first connecting rod 622, driving the sliding block 623 to slide along the radial direction of the first air outlet grille 30.

[0112] The slider 623 is arranged radially relative to the second motor 61 along the first air outlet grille 30. After receiving the linear power transmitted by the first connecting rod 622, the slider 623 reciprocally slides 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, and the first end is rotationally connected with the slider 623, and the second end is rotationally connected with the first air deflector 41. The linear reciprocating motion of the slider 623 is converted into the reciprocating swing of the first air deflector 41 around the second axis, i.e., the swing axis of the air deflector 40, and all the air deflectors 40 are driven to swing synchronously through the linkage structure between the air deflectors 40.

[0113] Therefore, by adopting the rigid connecting rod cooperating with the slider 623, the transmission process has no elastic deformation, and the rotation angle of the output end of the second motor 61 can be accurately converted into the swing angle of the air deflector 40. For example, the second motor 61 rotates by 180°, the slider 623 slides by a preset distance, and the air deflector 40 swings by 15°. The swing 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.

[0114] The first transmission part 620 includes a rotating handle 6201, and the second transmission part 621 includes the first connecting rod 622, the slider 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 of multi-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.

[0115] In some embodiments, as shown in Figures 11 to 15 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 opening 32 in the direction of the first air deflector 41, the transmission assembly 62 extends from the mounting shell 31 to the first air deflector 41 through the avoiding opening 32, the side wall of the avoiding opening 32 is provided with a guide groove 321 in the radial direction of the first air outlet grille 30, and the slider 623 is slidingly connected with the guide groove 321.

[0116] In this way, the guide groove 321 restricts the transverse deviation or rotation of the slider 623, and ensures that the slider 623 always moves linearly along the radial direction of the first air outlet grille 30, thereby preventing the first connecting rod 622 and the second connecting rod 624 from generating additional torque due to the deviation of the slider 623, and further preventing the swing angle of the air deflector 40 from deviating or the transmission from being stuck.

[0117] The mounting shell 31 houses 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 direct adhesion of dust and condensed water to the transmission components, preventing rust and dust accumulation from increasing the transmission resistance or causing jamming, avoiding accidental touch or collision of the transmission components during maintenance, reducing the risk of interference with other structures during grid rotation, and protecting the integrity of the transmission system.

[0118] In some embodiments, as shown in Figure 9 The first end of the first connecting rod 622 is provided with a first rotating groove 6221, and 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 rotationally connected with the first rotating groove 6221. The rotating axis of the first rotating part 6202 is parallel to the rotating axis of the second motor 61.

[0119] 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 rotationally connected with the second rotating groove 6222. The rotating axis of the second rotating part 6231 is parallel to the rotating axis of the second motor 61.

[0120] 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 adapted to the inner wall of the first rotating groove 6221 and can be completely inserted into the groove to form an embedded fit for rotational connection. The rotating axis of the first rotating part 6202 is parallel to the rotating axis of the second motor 61.

[0121] When the second motor 61 drives the rotating handle 6201 to rotate around its axis, the first rotating part 6202 moves in a circular motion with the rotating handle 6201. It slides along the groove wall 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 pushing and pulling force on the first connecting rod 622, driving the first connecting rod 622 to swing and providing power for the subsequent linear motion of the sliding block 623. The same applies to the second rotating groove 6222 and the second rotating part 6231.

[0122] Thus, the design of the rotating part rotating in the rotating groove allows the first connecting rod 622 to flexibly adjust the angle with the rotating handle 6201 and the sliding block 623 during swinging, 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 synchronously rotate 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 sliding block 623 can also adapt to the swinging angle through the rotation of the second rotating part 6231, ensuring smooth transmission without resistance.

[0123] The axes of all rotating parts are parallel to the motor axis, so that the movement of the transmission assembly 62 is concentrated in the same vertical plane, there is no spatial cross movement, 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, only leaving the rotation freedom around the axis, ensuring that the power of the first connecting rod 622 can be accurately transmitted to the sliding block 623, avoiding power loss or movement deviation caused by loose connection.

[0124] Among them, 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 convex shafts, hemispherical protrusions, etc., which are not limited in the present application.

[0125] 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.

[0126] 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.

[0127] In this way, the connection between the second connecting rod 624 and the sliding block 623 and the first air deflector 41 is all rigidly connected through shaft sleeves, without transmission gap, the linear motion of the sliding block 623 can be directly converted into the swinging torque of the air deflector 40 through the second connecting rod 624, with high power transmission efficiency; the extension direction of the rotating arm forms the best torque transmission angle with the swinging direction of the first air deflector 41, 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 adjusting response speed.

[0128] The shaft sleeve type connection has a large contact area, can disperse the force during transmission, avoids local stress concentration, and has high fault tolerance for assembly position. The sleeve of the second connecting rod 624 only needs to be sleeved into the rotating arm to complete assembly, without the need for precise alignment of hole positions, thereby reducing the assembly difficulty and precision requirement of the production line, having strong adaptability, and being convenient for batch production and model iteration.

[0129] In some embodiments, as shown in Figure 5 The plurality of guide vanes 40 are connected in transmission through the third connecting rod 42 to make the plurality of guide vanes 40 swing synchronously.

[0130] In this way, the third connecting rod 42 is connected to the first guide vane 41 and the remaining guide vanes 40 as a bridge, and synchronously transmits the swinging power of the first guide vane 41 to all the guide vanes 40. 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 the guide vanes 40 are completely consistent, and avoiding the problem of swing lag or angle deviation of part of the guide vanes 40.

[0131] The connection between the third connecting rod 42 and each guide vane 40 is provided with a rotating pair, ensuring that the guide vane 40 can swing flexibly around its own rotating shaft, and at the same time, the third connecting rod 42 only transmits swinging power and does not interfere with the rotating freedom of the guide vane 40.

[0132] The plurality of guide vanes 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 guide vanes 40, and the spacing of each connection point is consistent with the arrangement spacing of the guide vanes 40, ensuring that the third connecting rod 42 can synchronously pull or push all the guide vanes 40 in a straight line direction after connection, and avoiding transmission jamming caused by mispositioning of the connection points.

[0133] 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.

[0134] In this way, 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, avoiding distortion or deviation of the frame body after long-term use, and ensuring smooth rotation of the grille.

[0135] The connecting arm 22 is connected to 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 the two ends, thereby dispersing the local stress and avoiding bending deformation of the connecting arm 22 due to excessive cantilever stress, and ensuring the stable position of the second motor 61.

[0136] In some embodiments, as shown in Figure 4 and Figure 12 The first air outlet grille 30 includes a second annular frame 33 located in the first annular frame 21, and the second annular frame 33 is provided with a toothed disc 331.

[0137] As shown in Figure 4 The first motor 51 is fixed on 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.

[0138] In this way, 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 the deviation of the air outlet direction caused by transmission error. The double annular frames are concentrically nested, the rotation axis is unique, and the first air outlet grille 30 will not produce eccentric shaking during rotation. In combination with the continuous transmission of the gear 511 engagement, the vibration and noise during rotation can be significantly reduced, and the quietness of product operation can be improved.

[0139] 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.

[0140] When the angular velocity of the rotation of the first air outlet grille 30 is the same as the angular velocity of the rotation of the second motor 61, the air deflector 40 rotates with the first air outlet grille 30, and the air deflector 40 does not swing.

[0141] 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.

[0142] In this way, the three working conditions correspond to three air adjusting modes, which can be flexibly switched according to the user's use scene, and solve the problem of single air adjusting function of the traditional air adjusting function.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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 suitable 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.

[0149] 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.

[0150] 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 they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for 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.
