Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an air conditioner. Background Technology

[0002] In the field of air conditioning equipment, especially in cabinet air conditioners with air conditioning functions, precise control of the air outlet grille and air guide plate is crucial for achieving comfortable and efficient air conditioning.

[0003] In related technologies, when the cabinet air conditioner activates the air conditioning function, the air outlet grille needs to rotate back and forth within a preset angle range to initially change the air outlet direction. At the same time, the air guide plate installed on the air outlet grille will also rotate synchronously. Based on this, in order to achieve further fine adjustment of the air outlet direction, a drive component is usually set at the rotation axis of the air outlet grille to drive the air guide plate to swing around its own swing axis.

[0004] However, as the air outlet grille continues to rotate, the wires connecting the aforementioned drive components are frequently subjected to tension and torque, which can easily lead to stress concentration at a certain point on the wires (for example, the connection point between the wires and the aforementioned drive components). The wires repeatedly bend at this point, eventually leading to fatigue and breakage. As a result, the drive components that drive the air guide plate to swing cannot receive power supply, and the function of the air guide plate in finely adjusting the air outlet direction fails. Utility Model Content

[0005] This application discloses an air conditioner that can prevent wires from breaking, thereby ensuring the reliability of airflow direction adjustment.

[0006] To achieve the above objectives, this application discloses an air conditioner, comprising:

[0007] Cabinet unit, the cabinet unit includes:

[0008] A housing, on which an air outlet is provided;

[0009] A fixed bracket is fixedly mounted on the housing and located at the air outlet;

[0010] An air outlet grille is rotatably mounted on the fixed bracket.

[0011] An air guide plate is installed on the air outlet grille. When the air outlet grille rotates relative to the fixed bracket, the air outlet grille can drive the air guide plate to rotate, thereby changing the air outlet direction.

[0012] A first drive assembly is used to drive the air outlet grille to reciprocate and rotate.

[0013] A second driving component, used to drive the air guide plate to swing, the second driving component includes:

[0014] A first motor is mounted on the air outlet grille and located at the rotation axis of the air outlet grille.

[0015] A wire having a first connection end and a second connection end, the first connection end being connected to the first motor, and the second connection end being used to connect to a power source;

[0016] The conductor anti-torsion structure includes:

[0017] The guide is fixed relative to the air outlet grille. During the process of the air outlet grille rotating and driving the first motor to reciprocate, the guide can guide a portion of the wire near the first connection end to limit the bending curvature of the wire in contact with the guide.

[0018] Thus, when the air outlet grille rotates forward, the guide component guides the wire to maintain a smooth arc transition in one direction; when the air outlet grille rotates in the opposite direction, the guide component guides the wire to maintain a smooth arc transition in the opposite direction, and always maintains a guiding effect on the wire, ensuring that the wire is effectively protected during the reciprocating rotation process, and will not twist or entangle due to frequent changes in direction, and will avoid direct bending of the wire, thereby avoiding excessive stress at the bending point due to excessive bending of the wire, minimizing the possibility of wire breakage during the reciprocating rotation of the air outlet grille, and thus ensuring the reliability of the air outlet direction adjustment.

[0019] This application also provides an air conditioner, wherein the guide member includes:

[0020] A first guide member has a first guide surface, which is an arc surface and protrudes toward the wire;

[0021] The second guide member has a second guide surface, which is an arc surface and protrudes toward the wire, and the wire is located between the first guide surface and the second guide surface.

[0022] Thus, when the air vent grille rotates clockwise (e.g., counterclockwise), the first guide surface of the first guide member plays a major guiding role. Since the first guide surface is an arc surface convex towards the conductor, the conductor will bend along the first guide surface. The arc surface design allows the conductor to be tensioned in a relatively smooth curve, avoiding sharp bends and effectively dispersing the stress on the conductor during tensioning, reducing the risk of conductor damage due to stress concentration.

[0023] This application also provides an air conditioner, wherein the anti-twist structure for the wire further includes:

[0024] A blocking arm is disposed on the fixed bracket. The blocking arm has a blocking surface, which is an arc surface that extends along the rotation path of the air outlet grille. The blocking surface is used to prevent the wire from detaching from the fixed bracket.

[0025] In this way, during the rotation of the air vent grille, the blocking surface can prevent the wire from detaching from the fixed bracket, avoiding the wire from swinging randomly inside the air conditioner and preventing it from getting tangled or colliding with other components, thus ensuring the orderly movement of the wire. For example, when the air vent grille rotates rapidly, without the restriction of the blocking surface, the wire may be thrown onto surrounding parts, causing damage or malfunction.

[0026] This application also provides an air conditioner in which, along a direction perpendicular to the rotation axis of the air outlet grille, the length of the first guide member is configured such that, during the rotation of the air outlet grille driving the first motor to rotate, the minimum distance between the end of the first guide member away from the rotation axis and the blocking surface is greater than the diameter of the wire.

[0027] Along a direction perpendicular to the rotation axis of the air outlet grille, the length of the second guide member is configured such that, during the rotation of the air outlet grille causing the first motor to rotate in the opposite direction, the second guide member can push the wire to reset, and in the rotation direction of the air outlet grille, the opposite direction is the direction from the second guide member to the first guide member.

[0028] Thus, the minimum distance between the end of the first guide member away from the rotation axis and the blocking surface is greater than the diameter of the wire. This ensures that the wire is not squeezed by the first guide member and the blocking surface during the rotation of the air outlet grille. When the air outlet grille drives the first motor to rotate in the opposite direction, the second guide surface uses its arc surface to contact the wire and push the wire back to the initial position so that it can continue to maintain a good state during subsequent rotation.

[0029] This application also provides an air conditioner, wherein the anti-twist structure for the wire includes:

[0030] A first positioning component is fixed relative to the air outlet grille, and a first fixing part is provided on the first positioning component;

[0031] The first part of the conductor is fixed to the first wire fixing part, and the guide is disposed near the first wire fixing part to guide the conductor passing through the first wire fixing part.

[0032] In this way, the wire between the first connecting end and the first position (i.e. the part of the wire connecting the first motor) can remain stationary relative to the first motor during the rotation of the air outlet grille, thereby preventing the first connecting end from detaching from the first motor during the rotation of the air outlet grille, maintaining the stability of the connection, reducing contact resistance, and reducing the possibility of safety hazards such as overheating and arcing caused by poor contact.

[0033] This application also provides an air conditioner, wherein the anti-twist structure for the wire further includes:

[0034] The second positioning member is fixedly mounted on the fixed bracket and is farther away from the first motor relative to the first positioning member. The second positioning member is provided with a second wire fixing part.

[0035] The second part of the conductor is fixed to the second fixed part. The portion between the first part and the second part is a redundant segment. The length of the redundant segment is greater than or equal to the maximum distance between the first fixed part and the second fixed part. The maximum distance is configured as the maximum distance between the first fixed part and the second fixed part when the air outlet grille reciprocates. The guide can guide the redundant segment.

[0036] In this way, the first part of the wire is fixed relative to the air outlet grille, and the second part is fixed relative to the fixed bracket. The two ends of the redundant section are precisely positioned, so that the connection position between the wire and the first motor will not sway or bend significantly due to the movement of the air outlet grille. This restricts the range of motion of the wire. The redundant section can reasonably extend and retract according to the change in the distance between the first and second fixed parts, buffering the tension and torque on the wire. Through this continuous buffering, the concentration of tension and torque at a certain point is avoided, and the copper wire is prevented from breaking at a certain point due to frequent stretching and twisting. This ensures the effective operation of the second drive component and the reliability of the air outlet direction adjustment.

[0037] This application also provides an air conditioner, wherein the fixing bracket includes:

[0038] A ring frame is fixedly installed at the air outlet, and the air outlet grille is rotatably installed on the ring frame, with the axis of the ring frame coinciding with the axis of the air outlet grille.

[0039] A radial frame, the two ends of which are connected to the annular frame and located radially on the annular frame, the second positioning member is fixedly installed on the radial frame, the blocking arm is fixedly installed on the radial frame, and the wire between the second connecting end and the second part is supported on the radial frame.

[0040] In this way, the ring frame is fixedly installed at the air outlet, and the air outlet grille is rotatably installed on the ring frame, with their axes coinciding. This provides stable support and a precise axis of rotation for the air outlet grille, ensuring that it can rotate smoothly around the fixed axis, thereby achieving effective adjustment of the air outlet direction. The radial frame extends radially along the ring frame and is connected to the ring frame at both ends. This structure provides an installation position for the second positioning component without occupying too much space, and also provides support for the wires, making the overall structure of the fixed bracket more compact and making reasonable use of the space around the air outlet.

[0041] This application also provides an air conditioner, wherein both the first wire fixing part and the second wire fixing part are elastic clips.

[0042] In this way, the elastic clip can generate a fastening force through its own elastic deformation, firmly fixing the wire in the designated position and preventing the wire from shifting or shaking due to external forces, thus ensuring the stability of the electrical connection. During installation, simply place the wire into the elastic clip, and the clip's elasticity will automatically hold the wire tightly. During disassembly, gently press the clip to open it, and the wire can be easily removed without the need for additional tools. The operation is simple and convenient, greatly improving the efficiency of installation and maintenance.

[0043] This application also provides an air conditioner, wherein the air outlet grille further includes:

[0044] The mounting box is located at the rotation center of the air outlet grille, the first motor is located inside the mounting box, and the mounting box has an opening;

[0045] The cover is detachably installed at the opening of the mounting box, and the cover is provided with a wiring hole through which the wire passes.

[0046] Thus, the cover is provided with wiring holes, through which the wires are arranged to make the wiring neater and more standardized, avoiding the wires being exposed in a messy manner, reducing the risk of wire damage, and also helping to maintain the overall clean and beautiful appearance of the air outlet grille.

[0047] This application also provides an air conditioner, wherein the first positioning member is fixed to the cover by a snap-fit ​​structure, and the first wire fixing part is disposed near the wiring hole.

[0048] In this way, fixing the first positioning component to the cover can accurately position the wire near the wiring hole, ensuring that the wire is precisely fixed at the beginning after passing through the wiring hole, preventing it from shaking or shifting at will, making the wire's path more regular. Furthermore, the first wire fixing part is set close to the wiring hole, which can provide support and protection at the point where the wire passes through the wiring hole, avoiding damage to the insulation layer of the wire due to friction, pulling, etc. at the edge of the wiring hole, reducing the probability of electrical faults such as short circuits, and extending the service life of the wire.

[0076] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0077] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0078] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0079] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0080] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components whose specific types and structures may be the same or different, and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0081] As mentioned in the background section, in the prior art, as the air outlet grille continues to rotate, the wires on the drive component that drives the air guide plate are frequently subjected to tension and torque, which can easily lead to stress concentration on a certain point on the wire (for example, the connection position between the wire and the aforementioned drive component). The wire repeatedly moves and bends at this position, eventually leading to fatigue and breakage. As a result, the drive component that drives the air guide plate to swing cannot obtain power supply, and the function of the air guide plate in finely adjusting the air outlet direction fails.

[0082] To address the aforementioned issues, this application provides an air conditioner in which, when the air outlet grille rotates in the forward direction, a guide member is used to guide the wire to bend in one direction, thereby limiting the bending curvature of the wire at the contact portion with the guide member and minimizing the risk of breakage of the wire during the reciprocating rotation of the air outlet grille, thus ensuring the reliability of the air outlet direction adjustment.

[0083] The following will describe specific embodiments and appendices. Figure 1-11The technical solution of the air conditioner in this application will be further explained.

[0084] like Figure 1 As shown, the air conditioner 1 includes a cabinet unit 10, wherein the cabinet unit 10 is an indoor unit of the split air conditioner 1 with a floor-standing design, which is usually placed on the indoor floor, and the compressor and other refrigeration equipment are located in the outdoor unit. The indoor unit and the outdoor unit are connected to each other through pipes and lines to work.

[0085] like Figure 1 As shown, the cabinet air conditioner 10 may include a housing 11, on which an air outlet 11a is provided. The air outlet 11a is the outlet through which the air conditioner delivers treated hot or cold air to the room. Its size, shape and position design will affect the air outlet effect and indoor air circulation of the air conditioner.

[0086] like Figure 2 As shown, the cabinet unit may also include a fixed bracket 12, which is fixedly mounted on the casing and located at the air outlet 11a.

[0087] like Figures 2 to 4 As shown, the cabinet unit may also include an air outlet grille 13, which is rotatably mounted on the fixed bracket 12 and can rotate relative to the fixed bracket 12. Its function is to adjust the direction and angle of the air outlet, and it also plays a certain decorative and protective role for the air outlet 11a.

[0088] like Figure 2 As shown, the cabinet unit may also include an air guide plate (not shown in the figure), which is installed on the air outlet grille 13. When the air outlet grille 13 rotates relative to the fixed bracket 12, the air outlet grille 13 can drive the air guide plate to rotate, thereby changing the air outlet direction of the air outlet 11a. The air guide plate is installed at the air guide plate installation position 14a.

[0089] like Figure 2 and Figure 3 As shown, the cabinet air conditioner may also include a first drive assembly 15, which drives the air outlet grille 13 to reciprocate. The reciprocating rotation of the air outlet grille 13 is limited to a preset angle, which can be selected according to actual use, such as 30°, 60°, 90°, etc. It should be noted that the reciprocating rotation of the air outlet grille 13 within the preset angle is based on intermittent user adjustments, rather than continuous rotation during the operation of the cabinet air conditioner.

[0090] It typically consists of a drive unit 15a, a transmission device, etc. It controls the rotation of the motor to drive the air outlet grille 13 to rotate back and forth within a certain angle range, so as to achieve air outlet in different directions.

[0091] For example, such as Figure 2 and Figure 4As shown, the driving component 15a is a servo motor, which is fixed to a specific position on the fixed bracket 12 by bolts. A continuous tooth structure 15b is machined along the circumference of the edge of the air outlet grille 13. The tooth shape can be an involute tooth shape to ensure the smoothness and accuracy of the transmission. A gear 15c concentric with the output shaft of the servo motor is installed on the fixed bracket 12. The module and number of teeth of the gear 15c match the tooth structure 15b on the air outlet grille 13 to ensure good meshing. The gear 15c is rotatably mounted on the fixed bracket 12 through a bearing. After the servo motor starts, its output shaft drives the gear 15c on the fixed bracket 12 to rotate. Since the gear 15c meshes with the tooth structure 15b on the air outlet grille 13, the rotational motion of the gear 15c is transmitted to the air outlet grille 13. Under the forward and reverse control of the servo motor, the gear 15c also rotates in the forward and reverse directions, thereby driving the air outlet grille 13 to reciprocate within a preset angle range.

[0092] The cabinet unit 10 may also include a second drive assembly, which is used to drive the air guide plate to swing. The swing angle of the air guide plate can be controlled independently to further refine the adjustment of the air outlet direction.

[0093] like Figure 4 As shown, the second drive component may include a first motor 16a, which is mounted on the air outlet grille 13 and located at the rotation axis of the air outlet grille 13. It provides power for the swing of the air guide plate. The rotation of the motor drives the air guide plate to swing around the axis, thereby achieving precise control of the air outlet direction.

[0094] For example, a crank is fixed on the output shaft of the motor. The crank is an eccentric disk with a certain eccentricity between its center and the axis of the motor output shaft. A connecting seat is installed at one end of the air guide plate near the rotation axis of the air outlet grille 13. One end of the connecting rod is connected to the eccentric hole on the crank through a pin, and the other end is connected to the connecting seat of the air guide plate through a pin. In this way, when the motor output shaft rotates, it can be converted into the reciprocating swing of the connecting rod through the crank, thereby driving the air guide plate to swing around its own swing axis.

[0095] like Figures 5 to 8 As shown, the second drive component may include a wire 16b, which has a first connection end and a second connection end. The first connection end is connected to the first motor 16a, and the second connection end is used to connect to a power source to transmit electrical energy to the first motor 16a so that the first motor 16a can work normally.

[0096] like Figure 2 As shown, the cabinet unit 10 may also include a wire anti-twist structure 100, which is used to prevent the wire 16b from twisting or tangling during the rotation of the air outlet grille 13, so as to ensure the normal use of the wire 16b and the stability of the electrical connection.

[0097] In some possible embodiments, such as Figure 3 and Figure 4 As shown, the wire anti-twist structure 100 may include a guide member 130, which is fixed relative to the air outlet grille 13. During the process of the air outlet grille 13 rotating and driving the first motor 16a to reciprocate, the guide member 130 can guide a portion of the wire 16b near the first connection end to limit the bending curvature of the wire 16b in contact with the guide member 130.

[0098] The restriction on the curvature of the conductor 16b in contact with the guide 130 should be understood as preventing the conductor 16b from bending directly and maintaining a smooth arc transition.

[0099] If conductor 16b is bent directly, the copper wire at the bend will be subjected to extreme compression and stretching. This excessive stress will damage the crystal structure of the copper wire, accelerate its fatigue and aging, and easily lead to cracks and damage in the insulation layer. This will expose the copper wire inside conductor 16b, causing safety hazards such as leakage and short circuits. Moreover, once the insulation layer is damaged, it will also reduce the moisture-proof and dust-proof performance of conductor 16b, further affecting its service life.

[0100] In this embodiment, by setting a guide member 130, when the air outlet grille 13 rotates in the forward direction, the guide member 130 guides the wire 16b to maintain a smooth arc transition in one direction; when the air outlet grille 13 rotates in the reverse direction, the guide member 130 can guide the wire 16b to maintain a smooth arc transition in the opposite direction, and always maintains the guiding function of the wire 16b, ensuring that the wire 16b is effectively protected during the reciprocating rotation process, and will not be twisted or tangled due to frequent changes in direction, and will avoid direct bending of the wire 16b, thereby avoiding excessive stress at the bending position due to excessive bending of the wire 16b, and minimizing the possibility of breakage of the wire 16b during the reciprocating rotation of the air outlet grille 13, thus ensuring the reliability of the air outlet direction adjustment.

[0101] In some possible embodiments, such as Figures 5 to 8 As shown, the guide member 130 may include a first guide member 1301, the first guide member 1301 having a first guide surface 1301a, the first guide surface 1301a being an arc surface and protruding toward the wire 16b.

[0102] like Figures 5 to 8As shown, the guide member 130 may also have a second guide member 1302. The second guide member 1302 has a second guide surface 1302a. The second guide surface 1302a is an arc surface and protrudes toward the wire 16b. The wire 16b is located between the first guide surface 1301a and the second guide surface 1302a.

[0103] When the air vent grille 13 rotates clockwise (e.g., when it rotates counterclockwise, as...), Figure 6 As shown), the first guide surface 1301a of the first guide member 1301 plays a major guiding role. Since the first guide surface 1301a is an arc surface protruding towards the conductor 16b, the conductor 16b will bend along the first guide surface 1301a. The arc surface design allows the conductor 16b to be tensioned with a relatively smooth curve, avoiding sharp bends. In this way, the stress on the conductor 16b during tensioning is effectively distributed, reducing the risk of damage to the conductor 16b due to stress concentration. When the air outlet grille 13 rotates in the opposite direction (for example, when rotating clockwise, as shown in the image), the first guide surface 1301a plays a major guiding role. Figure 8 As shown, the second guide surface 1302a is also an arc surface protruding towards the conductor 16b. The conductor 16b will bend along the second guide surface 1302a. Thus, as the air outlet grille 13 reciprocates, the first guide surface 1301a and the second guide surface 1302a will alternately guide the conductor 16b, so that the conductor 16b always maintains a reasonable bending shape and movement trajectory, so that the guide component 130 can adapt to different rotation speeds and angle changes of the air outlet grille 13, and ensure that the conductor 16b can work stably under various working conditions.

[0104] Of course, the guide 130 is not limited to the above form. For example, the guide 130 can also be a pulley-type guide 130. During the rotation of the air outlet grille 13, the wire 16b passes around the pulley. The pulley will rotate as the wire 16b moves, providing a rolling support point for the wire 16b to guide the wire 16b to move along a predetermined path.

[0105] In some possible embodiments, such as Figures 5 to 8 As shown, the wire anti-twist structure 100 may also include a blocking arm 140, which is disposed on the fixed bracket 12. The blocking arm 140 has a blocking surface, which is an arc surface that extends along the rotation path of the air outlet grille 13. The blocking surface is used to prevent the wire 16b from detaching from the fixed bracket 12.

[0106] During the rotation of the air outlet grille 13, the blocking surface can prevent the wire 16b from detaching from the fixed bracket 12, thus preventing the wire 16b from swinging randomly inside the air conditioner and preventing it from getting tangled or colliding with other components. This ensures the orderly movement of the wire 16b. For example, if the wire 16b were not restricted by the blocking surface when the air outlet grille 13 rotates rapidly, it might be thrown onto surrounding components, causing damage or malfunction.

[0107] Furthermore, the arc-shaped blocking surface can provide continuous and smooth support and guidance for the conductor 16b, enabling the conductor 16b to move in an orderly manner within the defined routing space, reducing friction and collision between the conductor 16b and the blocking arm 140, and preventing the conductor 16b from twisting or deforming due to unnecessary obstruction.

[0108] In some possible embodiments, such as Figures 5 to 8 As shown, along the direction perpendicular to the rotation axis of the air outlet grille 13, the length of the first guide member 1301 is configured such that, during the rotation of the air outlet grille 13 driving the first motor 16a to rotate, the minimum distance between the end of the first guide member 1301 away from the rotation axis and the blocking surface is greater than the diameter of the wire 16b.

[0109] Along the direction perpendicular to the rotation axis of the air outlet grille 13, the length of the second guide member 1302 is configured such that, during the process of the air outlet grille 13 rotating and driving the first motor 16a to rotate in the opposite direction, the second guide member 1302 can push the wire 16b to reset. In the rotation direction of the air outlet grille, the opposite direction is the direction from the second guide member to the first guide member.

[0110] When the air outlet grille rotates forward or backward, for example, when the air outlet grille 13 drives the first motor 16a to rotate forward (i.e., from the first guide member 1301 to the second guide member 1302), the wire 16b will contact the first guide surface 1301a of the first guide member 1301 and begin to bend along the arc path of the first guide surface 1301a. In the direction perpendicular to the rotation axis of the air outlet grille 13, the minimum distance between the end of the first guide member 1301 away from the rotation axis and the blocking surface is greater than the diameter of the wire 16b. This ensures that the wire 16b will not be squeezed by the first guide member 1301 and the blocking surface during the forward or reverse rotation of the air outlet grille 13.

[0111] During forward rotation, the wire 16b may be deflected or deformed due to bending and rotation. When rotating in the reverse direction, it may get stuck at the blocking surface and be unable to move further. When the air outlet grille 13 drives the first motor 16a to rotate in the reverse direction (i.e., from the direction of the second guide 1302 to the first guide 1301), the wire 16b contacts the second guide surface 1302a of the second guide 1302. The second guide surface 1302a can push the wire 16b back to its initial position so that it can continue to maintain a good state during subsequent rotation.

[0112] In some possible embodiments, such as Figure 2 and Figure 9As shown, the wire anti-twist structure 100 may include a first positioning member 110, which is fixed relative to the air outlet grille 13, and a first wire fixing part 1101 is provided on the first positioning member 110.

[0113] like Figures 5 to 8 As shown, the first part of the wire 16b is fixed to the first wire fixing part 1101, and the guide member 130 is disposed near the first wire fixing part 1101 to guide the wire 16b that passes through the first wire fixing part 1101.

[0114] The first part of the wire 16b is fixed to the first wire fixing part 1101. In this way, the wire 16b between the first connecting end and the first position (that is, the part of the wire 16b connecting the first motor 16a) can remain stationary relative to the first motor 16a during the rotation of the air outlet grille 13. This prevents the first connecting end from detaching from the first motor 16a during the rotation of the air outlet grille 13, thereby maintaining the stability of the connection, reducing contact resistance, and reducing the possibility of safety hazards such as overheating and arcing caused by poor contact.

[0115] Furthermore, the guide member 130 is disposed close to the first wire fixing part 1101, which can guide the wire 16b passing through the first wire fixing part 1101, thereby preventing the wire 16b from bending at the first part and thus preventing stress concentration at the first part.

[0116] For example, when the guide member 130 is composed of a first guide member 1301 and a second guide member 1302 with arc surfaces having opposite convex directions, after the wire 16b passes through the first wire fixing part 1101, it will first contact the first guide member 1301 or the second guide member 1302. Taking the first guide member 1301 as an example, it has a first guide surface 1301a protruding towards the wire 16b. This arc surface will guide the wire 16b to start bending along the contour of the arc surface. Due to the presence of the arc surface, the wire 16b will not bend sharply at the first part, but will change direction in a relatively smooth way, avoiding stress concentration and damage caused by excessive bending.

[0117] Furthermore, the arc surfaces of the first guide member 1301 and the second guide member 1302 can restrict the wire 16b in the lateral direction. The first guide member 1301 and the second guide member 1302 are arranged opposite to each other and the arc surfaces protrude in opposite directions, forming a channel. The wire 16b moves within this channel, so that the wire 16b will not deviate to the sides during the rotation of the air outlet grille 13, ensuring that the wire 16b is always within the predetermined path range, thereby maintaining the stability of the connection between the wire 16b and the first motor 16a.

[0118] In some possible embodiments, such as Figures 5 to 8As shown, the wire anti-twist structure 100 may also include a second positioning member 120, which is fixedly mounted on the fixed bracket 12 and is located away from the first motor 16a relative to the first positioning member 110. A second wire fixing part is provided on the second positioning member 120.

[0119] like Figures 5 to 8 As shown, the second part of the wire 16b is fixed to the second wire fixing part, and the part between the first part and the second part is a redundant section. The length of the redundant section is greater than or equal to the maximum distance between the first wire fixing part 1101 and the second wire fixing part. The maximum distance is configured to be the maximum distance between the first wire fixing part 1101 and the second wire fixing part when the air outlet grille 13 reciprocates. The guide member 130 can guide the redundant section.

[0120] The "maximum distance" refers to the maximum straight-line distance that can be achieved between the first fixed wire portion 1101 on the first positioning member 110 and the second fixed wire portion on the second positioning member 120 during the reciprocating rotation of the air outlet grille 13. The length of the redundant section is designed to be greater than or equal to this "maximum distance" in order to ensure that the wire 16b will not be stretched or twisted due to the change in the distance between the two fixed wire portions during the rotation of the air outlet grille 13.

[0121] Specifically, when the air conditioner activates its air conditioning function, the first drive component begins to operate, driving the air outlet grille 13 to rotate reciprocally within a preset angle range. Since the air outlet grille 13 is rotatably mounted on the fixed bracket 12, it rotates in a circular motion around the central axis of the fixed bracket 12. Simultaneously, the air guide plate mounted on the air outlet grille 13 rotates synchronously with the air outlet grille 13, thus initially changing the airflow direction from the vent.

[0122] Subsequently, the first motor 16a in the second drive assembly can be started. The first motor 16a is located at the rotation axis of the air outlet grille 13. Its output shaft drives the air guide plate to swing around its own swing axis, thereby achieving further fine adjustment of the air outlet direction.

[0123] During the movement of the air outlet grille 13 and the air guide plate, the wire 16b is responsible for transmitting electrical energy to the first motor 16a. The wire 16b between the first part and the first connection end is fixed relative to the air outlet grille 13 and will move synchronously with the air outlet grille 13. The wire 16b between the second part and the second connection end is fixed relative to the fixed bracket 12 and its position remains unchanged.

[0124] As the air outlet grille 13 rotates, the distance between the first fixed wire portion 1101 and the second fixed wire portion changes continuously. The redundant segment will be stretched or relaxed accordingly based on the change in the distance between the first fixed wire portion 1101 and the second fixed wire portion. When the air outlet grille 13 rotates in one direction, the distance between the first fixed wire portion 1101 and the second fixed wire portion increases, and the redundant segment is stretched. When the air outlet grille 13 rotates in the opposite direction, the distance between the first fixed wire portion 1101 and the second fixed wire portion decreases, and the redundant segment gradually relaxes.

[0125] In other words, by fixing the first part of the wire 16b relative to the air outlet grille 13 and the second part relative to the fixed bracket 12, the two ends of the redundant section are precisely positioned. This prevents the connection between the wire 16b and the first motor 16a from swaying or bending significantly due to the movement of the air outlet grille 13, thus limiting the range of motion of the wire 16b and preventing the connection from bending due to frequent stress. When the air outlet grille 13 rotates in one direction, the distance between the first wire fixing part 1101 and the second wire fixing part increases, and the redundant section is stretched. The stress that might have been concentrated at a certain point on the wire 16b (e.g., stress concentrated at the first part) is distributed to the various parts of the redundant section that contact the first guide member 1301, thus avoiding stress. Similarly, when the air outlet grille 13 rotates in the opposite direction and the distance decreases, the redundant section gradually relaxes, which effectively prevents the wire harness from repeatedly bending at this position due to stress concentration at a certain point. The stress is distributed to the various parts of the redundant section that contact the first guide member 1301. During the continuous reciprocating rotation of the air outlet grille 13, the redundant section reasonably expands and contracts according to the change in the distance between the first wire fixing part 1101 and the second wire fixing part, buffering the tension and torque on the wire 16b. Through this continuous buffering, the concentration of tension and torque at a certain point is avoided, and the copper wire is prevented from breaking at a certain point due to frequent stretching and twisting. This ensures the effective operation of the second drive component and the reliability of the air outlet direction adjustment.

[0126] Furthermore, during the rotation of the air outlet grille 13, the distance between the first wire fixing part 1101 and the second wire fixing part changes continuously. The redundant section wire 16b needs to be stretched or relaxed accordingly. The guide member 130 can play a guiding role in this process, ensuring that the redundant section wire 16b will not entangle or knot during the extension and contraction. When the redundant section is stretched, the guide member 130 guides the wire 16b to be tensioned in a specific direction and sequence to prevent the wires 16b from getting tangled together. When the redundant section is relaxed, the guide member 130 can guide the wires 16b to be folded or bent in an orderly manner to avoid the wires 16b from piling up and getting messy. This minimizes the risk of the wires 16b breaking during the reciprocating rotation of the air outlet grille 13, further ensuring the reliability of the air outlet direction adjustment.

[0127] In some possible embodiments, such as Figure 3As shown, the fixed bracket 12 may include an annular frame 12a, which is fixedly installed at the air outlet. The air outlet grille 13 is rotatably installed on the annular frame 12a, and the axis of the annular frame 12a coincides with the axis of rotation of the air outlet grille 13.

[0128] The fixed bracket 12 may also include a radial bracket 12b, the two ends of which are connected to the annular bracket 12a and extend radially along the annular bracket 12a. The second positioning member 120 is fixedly installed on the radial bracket 12b, the blocking arm 140 is fixedly installed on the radial bracket 12b, and the wire 16b between the second connecting end and the second part is supported on the radial bracket 12b.

[0129] Thus, the annular frame 12a is fixedly installed at the air outlet, and the air outlet grille 13 is rotatably installed on the annular frame 12a, with their axes coinciding. This provides stable support and a precise axis of rotation for the air outlet grille 13, ensuring that the air outlet grille 13 can rotate smoothly around the fixed axis, thereby achieving effective adjustment of the air outlet direction.

[0130] The radial bracket 12b extends radially along the annular bracket 12a and is connected to the annular bracket 12a at both ends. This structure provides an installation position for the second positioning member 120 without occupying too much space, and also provides support for the wire 16b. This makes the overall structure of the fixed bracket 12 more compact, makes reasonable use of the space around the air outlet, and supports the wire 16b between the second connection end and the second part on the radial bracket 12b. This prevents the wire 16b from being hung randomly or rubbed or tangled with other components, reduces the risk of damage to the wire 16b, and improves the stability and safety of the electrical connection.

[0131] In addition, multiple wire fixing parts 150 may be provided on the radial frame 12b to fix the wire 16b to the radial frame 12b.

[0132] In some possible embodiments, both the first wire fixing portion 1101 and the second wire fixing portion are elastic snaps.

[0133] The elastic clips generate a tightening force through their own elastic deformation, firmly fixing the wire 16b in the designated position and preventing the wire 16b from shifting or shaking due to external forces, thus ensuring the stability of the electrical connection. During installation, simply place the wire 16b into the elastic clip, and the clip's elasticity will automatically hold the wire 16b tightly. During disassembly, gently press the clip to open it, and the wire 16b can be easily removed without the need for additional tools. The operation is simple and convenient, greatly improving the efficiency of installation and maintenance.

[0134] Furthermore, the elastic buckle has a certain elastic deformation capability, which can adapt to wires 16b of different diameters. Whether it is a thinner wire 16b or a thicker wire 16b, it can be tightly fixed through the adaptive adjustment of the elastic buckle, thereby improving the versatility and compatibility of the first wire fixing part 1101 and the second wire fixing part.

[0135] Of course, the first wire securing part 1101 and the second wire securing part are not limited to elastic buckles. For example, they can also be cable ties, wire clips, insulating tape, etc.

[0136] In some possible embodiments, such as Figure 4 As shown, the air outlet grille 13 may also include a mounting box 13a, which is located at the rotation center of the air outlet grille 13. The first motor 16a is located inside the mounting box 13a, and the mounting box 13a has an opening.

[0137] like Figure 10 As shown, the air vent grille 13 may also include a cover 13b, which is detachably installed at the opening of the mounting box 13a. The cover 13b is provided with a wiring hole 13b1, through which the wire 16b passes.

[0138] The cover 13b can be detachably installed at the opening of the mounting box 13a, and can be any form of connection such as plug-in, snap-fit, or threaded connection, which is not limited here.

[0139] The mounting box 13a provides a fixed mounting position for the motor, facilitating its installation and removal. This is beneficial for assembly during production and for maintenance or replacement during later use. Meanwhile, the cover 13b is detachably mounted at the opening of the mounting box 13a, further facilitating the operation of the motor inside the mounting box 13a. Maintenance work can be performed by opening the cover 13b without disassembling the entire air outlet grille 13, thus improving maintenance efficiency.

[0140] Furthermore, the cover 13b is provided with a wiring hole 13b1, through which the wire 16b passes, making the arrangement of the wire 16b more neat and standardized, avoiding the wire 16b being exposed in a messy manner, reducing the risk of damage to the wire 16b, and also helping to maintain the overall neat and beautiful appearance of the air outlet grille 13.

[0141] The wiring hole 13b1 can be set on the rotation axis of the exhaust grille so that the wire 16b can pass through directly and avoid contact with the lower side of the cover 13b as much as possible, so as to avoid stress concentration at the position where the wire 16b contacts the lower side of the cover 13b.

[0142] In some possible embodiments, such as Figure 4 and Figure 10As shown, the first positioning member 110 is fixedly mounted on the cover 13b, and the first wire fixing part 1101 is positioned near the wire routing hole 13b1.

[0143] Fixing the first positioning part 110 to the cover 13b can accurately position the wire 16b near the wiring hole 13b1, ensuring that the wire 16b is precisely fixed at the beginning after passing through the wiring hole 13b1, preventing it from shaking or shifting at will, making the wire 16b's path more regular. In addition, the first wire fixing part 1101 is set close to the wiring hole 13b1, which can provide support and protection at the part where the wire 16b passes through the wiring hole 13b1, avoiding damage to the insulation layer of the wire 16b at the edge of the wiring hole 13b1 due to friction, pulling, etc., reducing the probability of electrical faults such as short circuits, and extending the service life of the wire 16b.

[0144] The first positioning element 110 can be disposed on the outer surface of the cover 13b.

[0145] In some possible embodiments, such as Figure 10 As shown, the first positioning member 110 is detachably fixed to the cover 13b by a snap-fit ​​structure.

[0146] like Figure 11 As shown, the snap-fit ​​structure may include an elastic snap hook 13b2, which is disposed on the cover 13b;

[0147] like Figure 9 As shown, the snap-fit ​​structure may also include a snap-fit ​​part 1102, which is disposed on the first positioning member 110. When the first positioning member 110 is installed on the cover 13b along the central axis of the air outlet grille 13, the elastic hook 13b2 snaps into the snap-fit ​​part 1102 to fix the first positioning member 110 on the cover 13b.

[0148] When installing the first positioning member 110, simply align it with the elastic hook 13b2 on the cover 13b and press it down along the central axis of the air outlet grille 13. The elastic hook 13b2 will then snap into the locking part 1102, completing the installation without the need for additional tools. The operation is simple and quick. When disassembling, simply press the elastic hook 13b2 gently to disengage it from the locking part 1102, and the first positioning member 110 can be removed from the cover 13b, facilitating the maintenance, replacement, or adjustment of the first motor 16a or its related components.
