Description

Technical Field

[0001] This application relates to the field of air conditioning technology, such as an air guide mechanism and an air conditioner. Background Technology

[0002] Currently, air conditioners have become an indispensable appliance in people's work or life. Air conditioners can regulate indoor temperature, humidity and air purification, providing people with a comfortable living and working environment.

[0003] When an air conditioner blows air, hot or cold air from the heat exchanger is directly blown out of the air outlet. Especially when cold air is blown out directly, a large temperature difference is created relative to the original indoor air temperature, which can cause discomfort to the user. Furthermore, frequent exposure to this large temperature difference of cold air can easily lead to colds or "air conditioning sickness." Related technology provides a wall-mounted air conditioner, including a casing, a heat exchanger and a fan inside the casing, and a U-shaped air-guiding plate at the front of the casing. The air-guiding plate and the front casing form an air-guiding duct. Air that has not undergone heat exchange enters the air-guiding duct and mixes with the air blown out of the outlet duct, resulting in a gentler airflow.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] In related technologies, an air guide plate needs to be added to the outside of the air conditioner casing. The air guide plate is connected to the outside of the casing by a fixing device, which makes the overall structure of the air conditioner more complex and affects its aesthetics. At present, there is no air guiding mechanism that can move the air guide plate at the air outlet of the air conditioner with precise movement to guide air. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides an air guiding mechanism and an air conditioner, which enables the air guiding mechanism to accurately drive the air guide plate to rotate to the air intake position, and simplifies the structure of the air conditioner.

[0008] In some embodiments, the air guiding mechanism includes an air guide plate, a first arc-shaped rack, and a second arc-shaped rack. The air guide plate has a first position where the air outlet of the air conditioner is closed and a second position where air is drawn from outside the air conditioner. A slide rail is provided on the inner side of the air guide plate. One end of the first arc-shaped rack is hinged to the air guide plate, and one end of the second arc-shaped rack is slidably connected to the slide rail. Under the action of an external force, the first and second arc-shaped racks drive the air guide plate to extend from the first position to the middle position and then rotate to the second position. During the process of the air guide plate rotating from the middle position to the second position, the second arc-shaped rack moves relative to the first arc-shaped rack, and one end of the second arc-shaped rack slides within the slide rail. The relative motion trajectory between the first and second arc-shaped racks has a preset correlation with the length of the slide rail.

[0009] Optionally, the preset association relationship is: the relative motion trajectory is greater than the length of the slide.

[0010] Optionally, a limiting mechanism is provided between the first arc-shaped rack and the second arc-shaped rack. The limiting mechanism includes a limiting groove and a limiting post. The limiting groove is disposed on the side of the first arc-shaped rack along the length direction of the first arc-shaped rack. The limiting post is disposed on the side of the second arc-shaped rack opposite to the first arc-shaped rack and is slidably disposed in the limiting groove.

[0011] Optionally, the length of the limiting groove is equal to the relative motion trajectory.

[0012] Optionally, the second arc-shaped rack includes a bent section and a second connecting shaft. The bent section is disposed on one end of the second arc-shaped rack near the air outlet. The second connecting shaft is disposed on the free end of the bent section and is slidably disposed within the slide rail.

[0013] Optionally, the extension direction of the bent section is opposite to the bending direction of the second arc-shaped rack; when the air guide plate is in the middle position, the angle between the air guide plate and the horizontal direction is ω1, and the angle between the bent section and the air guide plate is ω2, where ω1 > ω2.

[0014] Optionally, when the air guide plate rotates from the middle position to the second position, the second arc-shaped rack rotates at an angle of ω3 relative to the first arc-shaped rack, and the relationship between ω3, ω2 and ω1 satisfies: ω3=ω1-ω2.

[0015] Optionally, the inner side of the air guide plate is also provided with a mounting hole, and one end of the first arc-shaped rack is provided with a first connecting hole. The mounting hole and the first connecting hole are hinged together by a connector.

[0016] Optionally, the air guiding mechanism further includes a gear, which is fixed inside the air conditioner. The gear is disposed inside the first arc-shaped rack and the second arc-shaped rack and meshes with the first arc-shaped rack and the second arc-shaped rack for transmission.

[0017] In some embodiments, the air conditioner includes the air guide mechanism described above.

[0018] The air guiding mechanism and air conditioner provided in this disclosure can achieve the following technical effects:

[0019] The air guiding mechanism provided in this embodiment includes an air guide plate, a first arc-shaped rack, and a second arc-shaped rack. The air guide plate has a first position with the air outlet closed and a second position with air intake. Under the action of an external force, the two arc-shaped racks first extend to the middle position and then rotate to the second position. During the rotation of the air guide plate from the middle position to the second position, the first and second arc-shaped racks move relative to each other, and one end of the second arc-shaped rack slides within a slide rail. The relative motion trajectory between the two arc-shaped racks is related to the length of the slide rail on the inner side of the air guide plate. By limiting the relationship between the relative motion trajectory and the slide rail length, the air guide plate can rotate from the middle position to the air intake position along a preset path, improving the accuracy of the air guiding mechanism's movement. Simultaneously, the air guide plate can move to the second position for air intake under the action of the two arc-shaped racks, eliminating the need for an external air intake mechanism on the air conditioner's casing, thus simplifying the air conditioner's structure. Furthermore, the air deflector in the second position directs the indoor airflow to the vicinity of the air outlet, and mixes it with the airflow blown out from the heat exchanger before being delivered, thus improving the gentleness of the airflow.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0043] This disclosure provides an air conditioner, such as... Figures 1 to 3 As shown.

[0044] In some embodiments, the air conditioner includes the air guide mechanism described above.

[0045] The air conditioner provided in this embodiment is a gentle, uniform air conditioner. The air guide mechanism can move the air guide plate 10 from a closed state to an air intake position outside the air conditioner, guiding the indoor airflow to the vicinity of the air outlet, where it mixes with the airflow blown from the heat exchanger before being blown towards the user. In this way, the airflow blown from the heat exchanger does not blow directly onto the user, improving user comfort. Furthermore, since the air intake channel is located outside the air conditioner, it does not result in a loss of airflow volume and eliminates the need for an external air intake device, simplifying the air conditioner's structure.

[0046] Optionally, a deflector is installed inside the air outlet of the air conditioner to guide airflow vertically.

[0047] Understandably, the function of the air guide plate 10 is to draw air from the room to the vicinity of the air outlet. The air outlet is equipped with a baffle plate, which can guide air vertically to meet different cooling or heating needs. The airflow from the baffle plate and the airflow guided to the air outlet by the air guide plate 10 mix at the air outlet and is then blown towards the user, thus achieving a uniform airflow effect.

[0048] In this embodiment of the disclosure, the first position of the air guide plate 10 is that it is in the closed state, and the second position of the air guide plate 10 is the air intake position.

[0049] Optionally, the air guide plate 10 is horizontal in the air intake position, with its air intake position located below the air conditioner and its upper edge located behind the air outlet of the air conditioner.

[0050] When the air guide plate 10 is in a horizontal position, its upper edge is located below the air conditioner and behind the air outlet. This ensures that the air guide plate 10 does not obstruct the air outlet when the air conditioner is blowing air downwards, thus not affecting the air conditioner's cooling or heating performance. Furthermore, the airflow from the heat exchanger does not blow directly onto the air guide plate, preventing condensation from forming on it.

[0051] Optionally, when the air guide plate 10 is in a horizontal position, the distance between the air guide plate 10 and the lower housing of the air conditioner is greater than 30 mm.

[0052] In this embodiment, the air guide plate 10 functions to guide airflow. When the air conditioner is turned on, the air guide plate 10 moves from the closed state to the intermediate position, and then moves to the horizontal state. The air guide plate 10 will not rotate or flip in the horizontal state. In the horizontal state, the air guide plate 10 maintains a preset distance from the lower casing of the air conditioner. It is understood that when the preset distance is small, some airflow noise may be generated between the air guide plate 10 and the lower casing of the air conditioner, and it will not effectively guide airflow. Setting the preset distance to greater than 30 mm allows the air guide plate 10 to have a better airflow effect, and no other noise will be generated during the airflow process. For example, the preset distance can be 40 mm, 50 mm, 60 mm, or 100 mm, etc.

[0053] This disclosure also provides an air guiding mechanism, such as... Figures 4 to 11 As shown.

[0054] In some embodiments, the air guiding mechanism includes an air guide plate 10, a first arc-shaped rack 20, and a second arc-shaped rack 30. The air guide plate 10 has a first position where the air outlet of the air conditioner is closed and a second position where air is drawn from outside the air conditioner. A slide rail 121 is provided on the inner side of the air guide plate 10. One end of the first arc-shaped rack 20 is hinged to the air guide plate 10, and one end of the second arc-shaped rack 30 is slidably connected to the slide rail 121. Under the action of an external force, the first arc-shaped rack 20 and the second arc-shaped rack 30 drive the air guide plate 10 to extend from the first position to the middle position and then rotate to the second position. During the process of the air guide plate 10 rotating from the middle position to the second position, the second arc-shaped rack 30 moves relative to the first arc-shaped rack 20, and one end of it slides in the slide rail 121. The relative motion trajectory between the first arc-shaped rack 20 and the second arc-shaped rack 30 has a preset correlation with the length of the slide rail 121.

[0055] The air guiding mechanism provided in this embodiment includes an air guide plate 10, a first arc-shaped rack 20, and a second arc-shaped rack 30. The air guide plate 10 has a first position with the air outlet closed and a second position with air intake. Under the action of an external force, the two arc-shaped racks first extend to the middle position and then rotate to the second position. During the rotation of the air guide plate 10 from the middle position to the second position, the first arc-shaped rack 20 and the second arc-shaped rack 30 move relative to each other, and one end of the second arc-shaped rack 30 slides within the slide rail 121. The relative motion trajectory between the two arc-shaped racks is related to the length of the slide rail 121 on the inner side of the air guide plate 10. By limiting the relationship between the relative motion trajectory and the length of the slide rail 121, the air guide plate 10 can rotate from the middle position to the air intake position along a preset path, improving the accuracy of the air guiding mechanism's movement. At the same time, the air guide plate 10 can move to the second position for air intake under the action of the two arc-shaped racks, and the air intake mechanism does not need to be set on the outside of the air conditioner casing, simplifying the structure of the air conditioner. Furthermore, the air guide plate 10 in the second position directs the indoor airflow to the vicinity of the air outlet and mixes it with the airflow blown out from the heat exchanger before delivering the air, thus improving the gentleness of the airflow.

[0056] Optionally, the preset association relationship is: the relative motion trajectory is greater than the length of slide 121.

[0057] Understandably, taking a wall-mounted air conditioner as an example, the second position of the air guide plate 10 is located below the air conditioner and is horizontal. During the rotation of the air guide plate 10 from the middle position to the second position, the time the second arc-shaped rack 30 moves relative to the first arc-shaped rack 20 is equal to the time one end of the second arc-shaped rack 30 slides within the slide rail 121. The relative motion trajectory between the two arc-shaped racks is greater than the length of the slide rail 121, allowing the air guide plate 10 to rotate precisely from the middle position to the air-guiding position. This accurately controls the rotation angle of the air guide plate 10 and improves the precision of the air guiding mechanism's movement.

[0058] Optionally, the air guide plate 10 is flat. In this way, the indoor airflow passes through the inner side of the flat air guide plate 10, which has a better air-guiding effect.

[0059] Optionally, a limiting mechanism is provided between the first arc-shaped rack 20 and the second arc-shaped rack 30. The limiting mechanism includes a limiting groove 25 and a limiting post 36. The limiting groove 25 is disposed on the side of the first arc-shaped rack 20 along the length direction of the first arc-shaped rack 20. The limiting post 36 is disposed on the side of the second arc-shaped rack 30 opposite to the first arc-shaped rack 20, and is slidably disposed in the limiting groove 25.

[0060] like Figure 4As shown, the first arc-shaped rack 20 and the second arc-shaped rack 30 are arranged side by side and abut against each other. A limiting groove 25 is provided on the side of the first arc-shaped rack 20, and a limiting post 36 is provided on the corresponding side of the second arc-shaped rack 30. Optionally, the limiting groove 25 is elongated elliptical, and the limiting post 36 is cylindrical. The outer diameter of the limiting post 36 is equal to the width of the limiting groove 25, so that the limiting post 36 can slide along the limiting groove 25, limiting the movement trajectory of the second arc-shaped rack 30 according to the track of the limiting groove 25. In this embodiment, the limiting groove 25 is arranged along the length direction of the first arc-shaped rack 20, and the limiting groove 25 has an upper end away from the air guide plate 10 and a lower end close to the air guide plate 10.

[0061] In this embodiment, the air guide plate 10 moves from the closed state to the middle position, and then rotates to the air intake position. When the air guide plate 10 is in the closed state and the middle position, the limiting post 36 is located at the upper end of the limiting groove 25. When the air guide plate 10 rotates from the middle position to the air intake position, the limiting post 36 slides from the upper end of the limiting groove 25 to the lower end of the limiting groove 25. That is, during this process, the second arc-shaped rack 30 moves relative to the first arc-shaped rack 20. During the retraction of the air guide plate 10 from the air intake position, the limiting post 36 first slides from the lower end of the limiting groove 25 to the upper end of the limiting groove 25, and then the limiting post 36 drives the first arc-shaped rack 20 to move. When the limiting post 36 moves to the upper end of the limiting groove 25, the teeth on the first arc-shaped rack 20 and the second arc-shaped rack 30 correspond to the preset positions, preventing misalignment between them. This allows the first arc-shaped rack 20 and the second arc-shaped rack 30 to synchronously drive the air guide plate 10 back to the closed state, and tighten it in the closed state. The aforementioned limiting mechanism improves the accuracy of the rack assembly driving the air guide plate 10.

[0062] Optionally, the length of the limiting groove 25 is equal to the relative motion trajectory described above.

[0063] Understandably, the length L1 of the limiting groove 25 is greater than the length L2 of the slide rail 121. When the air guide plate 10 rotates from the middle position to the air intake position, the driving element only maintains a transmission connection with the second arc-shaped rack 30, and the first arc-shaped rack 20 stops moving. Therefore, the length of the limiting groove 25 is the relative motion trajectory of the two arc-shaped racks.

[0064] Optionally, the length of the limiting groove 25 is an integer multiple of the tooth width of the gear teeth on the second arc-shaped rack 30.

[0065] Understandably, the length of the limiting groove 25 is the relative motion trajectory of the second arc-shaped rack 30 relative to the first arc-shaped rack 20. During the retraction of the air guide plate 10, the second arc-shaped rack 30 first moves relative to the first arc-shaped rack 20, and then the two move synchronously, driving the air guide plate 10 to retract. By setting the length of the limiting groove 25 to an integer multiple of the tooth width, after the relative motion of the first arc-shaped rack 20 and the second arc-shaped rack 30, the teeth on them can correspond to the preset position, and misalignment will not occur.

[0066] Optionally, the second arc-shaped rack 30 includes a bent section 32 and a second connecting shaft 33. The bent section 32 is disposed on one end of the second arc-shaped rack 30 near the air outlet. The second connecting shaft 33 is disposed on the free end of the bent section 32 and is slidably disposed within the slide rail 121.

[0067] Optionally, one end of the second arc-shaped rack 30 is provided with a bent section 32, and the free end of the bent section 32 is provided with a second connecting shaft 33, which is used to slide with the air guide plate 10.

[0068] Optionally, one end of the air guide plate 10 is provided with a first mounting seat 11 and a second mounting seat 12. The first mounting seat 11 and the second mounting seat 12 are arranged side by side. The second mounting seat 12 is provided with the aforementioned slide rail 121, and the second connecting shaft 33 is slidably disposed in the slide rail 121.

[0069] Optionally, the slide 121 is straight, and the width of the slide 121 is equal to the outer diameter of the second connecting shaft 33. In this way, when the air guide plate 10 rotates from the middle position to the horizontal state, the second connecting shaft 33 can slide within the slide 121, so that the air guide plate 10 rotates about the hinge point between the first arc-shaped rack 20 and the air guide plate as the fulcrum.

[0070] When the air guide plate 10 is in the closed state, the second connecting shaft 33 is located at the starting end of the slide rail 121. As the air guide plate 10 extends from the closed state to the intermediate position, the second connecting shaft 33 remains at the starting end of the slide rail 121. Figure 7 As shown. When the air guide plate 10 rotates from the middle position to the horizontal state, the second connecting shaft 33 is located at the end of the slide rail 121, as shown. Figure 8 As shown. The starting end of the slide 121 is the end of the slide 121 near the upper edge of the air guide plate 10, and the ending end of the slide 121 is the end of the slide 121 near the middle of the air guide plate 10.

[0071] Optionally, the extension direction of the bent section 32 is opposite to the bending direction of the second arc-shaped rack 30; when the air guide plate 10 is in the middle position, the angle between the air guide plate 10 and the horizontal direction is ω1, and the angle between the bent section 32 and the air guide plate 10 is ω2, where ω1 > ω2.

[0072] When the air guide plate 10 is in the middle position, the state of the air guide mechanism is as follows: Figure 9 As shown by the dotted line in the diagram, the bent section 32 extends in a direction away from the bending direction of the second arc-shaped rack 30. By limiting the values ​​of ω1 and ω2 at the middle position, the range of the angle between the bent section 32 and the horizontal direction can be obtained, so that the second arc-shaped rack 30 can drive the air guide plate 10 to rotate from the middle position to the air intake position according to the preset track, thereby improving the accuracy of the second arc-shaped rack 30 in controlling the motion trajectory of the air guide plate 10.

[0073] Optionally, when the air guide plate 10 rotates from the middle position to the second position, the second arc-shaped rack 30 rotates at an angle of ω3 relative to the first arc-shaped rack 20, and the relationship between ω3, ω2 and ω1 satisfies: ω3=ω1-ω2.

[0074] When the air guide plate 10 rotates from the middle position to the air intake position, the rotation angle ω1 is equal to the sum of ω2 and ω3. ω1 can be obtained through experimental pre-setting, and the relationship between ω2 and ω3 can then be obtained. In this way, the rotation angle of the air guide plate 10 during the actual operation of the air guide plate 10 can be accurately controlled.

[0075] It is understandable that the arc length corresponding to ω3 is the length L1 of the limiting groove 25. By adjusting ω2, the length of the limiting groove 25 can be adjusted accordingly, thereby adjusting the length of the slide rail 121 on the air guide plate. In this way, the rack assembly can drive the air guide plate 10 to rotate to the air intake position according to the preset track.

[0076] Optionally, when the air guide plate 10 is in the closed state, the angle between the air guide plate 10 and the horizontal direction is ω0, and when the air guide plate 10 is in the middle position, the angle between the air guide plate 10 and the horizontal direction is ω1, where ω0 > ω1.

[0077] like Figure 9 As shown, Figure 9 The solid line in the middle represents the state of the rack assembly when the air guide plate 10 is in the closed state. Figure 9 The dashed line in the diagram represents the state of the rack assembly when the air guide plate 10 is in the middle position. During the process of extending the air guide plate 10 from the closed state to the middle position, not only does the position of the air guide plate 10 change, but the angle between the air guide plate 10 and the horizontal direction also decreases. That is, the air guide plate 10 also rotates during its extension, allowing it to reach a horizontal state for airflow as quickly as possible with minimal stroke.

[0078] Optionally, when the air guide plate 10 moves from the closed state to the middle position, the first arc-shaped rack 20 and the second arc-shaped rack 30 rotate at an angle of ω4, where ω4 = ω0 - ω1.

[0079] When the air guide plate 10 moves from the closed state to the intermediate position, the first arc-shaped rack 20 and the second arc-shaped rack 30 move synchronously, so that the rotation angle of both the first arc-shaped rack 20 and the second arc-shaped rack 30 is ω4. ω4 can be obtained through experiments or measurements of ω0 and ω1, and thus the arc length corresponding to ω4 can be determined, that is, the length of the teeth of the first arc-shaped rack 20 and the second arc-shaped rack 30 in the above process can be determined. By working backward from the above process, the movement control of the air guide plate 10 by the first arc-shaped rack 20 and the second arc-shaped rack 30 is made more accurate, enabling the air guide plate 10 to open to the air intake position.

[0080] Optionally, the inner side of the air guide plate 10 is also provided with a mounting hole 111, and one end of the first arc-shaped rack 20 is provided with a first connecting hole 22. The mounting hole 111 and the first connecting hole 22 are hinged together by a connector.

[0081] like Figure 5 As shown, one end of the first arc-shaped rack 20 is provided with a first connecting hole 22, which is used for hinged connection with the air guide plate 10. Figure 11 As shown, the first mounting base 11 of the air guide plate 10 is provided with a mounting hole 111, and the mounting hole 111 is hinged to the first connecting hole 22 by a connector. The line connecting the first connecting holes 22 at both ends of the air guide plate 10 is the axis of rotation of the air guide plate 10 from the middle position to the air intake position.

[0082] Optionally, the air guiding mechanism also includes a gear 40, which is fixed inside the air conditioner. The gear 40 is disposed inside the first arc-shaped rack 20 and the second arc-shaped rack 30 and meshes with the first arc-shaped rack 20 and the second arc-shaped rack 30 for transmission.

[0083] In this embodiment, the first arc-shaped rack 20 and the second arc-shaped rack 30 are connected to the same driving element. The driving element includes a gear 40. The gear 40 meshes with the first arc-shaped rack 20 or the second arc-shaped rack 30, thereby driving the air guide plate 10 to extend or rotate.

[0084] Optionally, the first side of the first arc-shaped rack 20 abuts against the second side of the second arc-shaped rack 30. The first side is provided with an inwardly recessed sliding cavity 23, and the second side is provided with a slide bar 34, which is slidably disposed in the sliding cavity 23.

[0085] In this embodiment, the first arc-shaped rack 20 and the second arc-shaped rack 30 are arranged side by side and slidably connected. The upper surfaces of both the first and second arc-shaped racks 20 and 30 are provided with teeth. A sliding cavity 23 is provided on the first side of the first arc-shaped rack 20 opposite to the second arc-shaped rack 30. Correspondingly, a slider 34 is provided on the second side of the second arc-shaped rack 30 at the corresponding position. When the first and second arc-shaped racks 20 move relative to each other, the slider 34 slides within the sliding cavity 23. That is, during the process of the air guide plate 10 moving from the middle position to a horizontal state, the first arc-shaped rack 20 stops moving, and the second arc-shaped rack 30 moves relative to the first arc-shaped rack 20. In other words, the slider 34 of the second arc-shaped rack 30 slides within the sliding cavity 23 of the first arc-shaped rack 20, so that the second arc-shaped rack 30 continues to transmit power with the driving element in a preset direction. The first arc-shaped rack 20 and the second arc-shaped rack 30 are slidably connected in the manner described above, which enables the second arc-shaped rack 30 to still move along a preset track when it is connected to the drive element, preventing the second arc-shaped rack 30 from derailing and improving the reliability of the motion component of this application.

[0086] Optionally, the bottom surface of the sliding cavity 23 extends towards the side near the second arc-shaped rack 30 and covers the lower surface of the second arc-shaped rack 30. In this way, the slider 34 on one side of the second arc-shaped rack 30 is within the sliding cavity 23, and the lower surface of the second arc-shaped rack 30 abuts against the bottom surface of the sliding cavity 23, further defining the direction of movement of the second arc-shaped rack 30 relative to the first arc-shaped rack 20 and improving the reliability of the movement of the second arc-shaped rack 30.

[0087] Optionally, the center of the circle containing the first arc-shaped rack 20 and the center of the circle containing the second arc-shaped rack 30 coincide on the same projection plane.

[0088] Understandably, both the first and second arc-shaped racks 20 and 30 are arc-shaped, which shortens the travel distance of the air guide plate 10 from the closed state to below the air conditioner, allowing the air guide plate 10 to reach the preset horizontal state as quickly as possible. Furthermore, the arc-shaped racks occupy less space on the side of the indoor unit, making them compatible with more types of air conditioners.

[0089] The center of the circle containing the first arc-shaped rack 20 and the center of the circle containing the second arc-shaped rack 30 coincide on the same projection plane, meaning that the curvature of the first arc-shaped rack 20 and the second arc-shaped rack 30 is the same. Thus, under the drive of the same driving element, the first arc-shaped rack 20 and the second arc-shaped rack 30 can first synchronously drive the air guide plate 10 to extend out of the air conditioner, and then the first arc-shaped rack 20 and the second arc-shaped rack 30 slide relative to each other, thereby driving the air guide plate 10 to rotate to a horizontal state.

[0090] Optionally, the upper surface of the first arc-shaped rack 20 is provided with a first toothed portion 21 and a toothless portion 26, and the upper surface of the second arc-shaped rack 30 is provided with a second toothed portion 31. The first toothed portion 21 is located close to the air guide plate 10, and the starting end of the toothless portion 26 is connected to the end of the first toothed portion 21. The effective length of the second toothed portion 31 is equal to the sum of the effective length of the first toothed portion 21 and the effective length of the toothless portion 26.

[0091] like Figure 5 As shown, the upper surface of the first arc-shaped rack 20 is sequentially provided with a first toothed portion 21 and a toothless portion 26. Optionally, the effective length of the first toothed portion 21 can be the length of the teeth of the drive element meshing with the first arc-shaped rack 20 during the process of the air guide plate 10 extending from the closed state to the intermediate position. Optionally, the effective length of the toothless portion 26 can be the length of the teeth of the drive element meshing with the second arc-shaped rack 30 when the air guide plate 10 rotates from the intermediate position to the air-guiding position. To better prevent the first arc-shaped rack 20 and the second arc-shaped rack 30 from misaligning during the return stroke of the air guide plate 10, the effective length of the toothless portion 26 can be extended and the effective length of the first toothed portion 21 can be shortened. Optionally, the effective length of the first toothed portion 21 can also be the length of the teeth of the drive element meshing with the first arc-shaped rack 20 when the air guide plate 10 moves from the closed state to the inclined position. Optionally, the effective length of the toothless portion 26 can also be the length of the teeth of the drive element that mesh with the second arc-shaped rack 30 when the air guide plate 10 moves from the inclined position to the air intake position.

[0092] like Figure 6 As shown, the upper surface of the second arc-shaped rack 30 is provided with a second tooth 31. The effective length of the second tooth 31 is the length of the tooth of the drive element that meshes with the second arc-shaped rack 30 during the process of the air deflector 10 extending from the closed state and rotating to the air intake position.

[0093] Understandably, the effective length of the second tooth 31 is greater than the effective length of the first tooth 21, allowing the air guide plate 10 to move along the following trajectory. When the air guide plate 10 is in the closed state, the gear 40 meshes synchronously with the first arc-shaped rack 20 and the second arc-shaped rack 30, causing the air guide plate 10 to extend to the middle position. When the air guide plate 10 is in the middle position, the gear 40 can mesh to the end of the first tooth 21, the first arc-shaped rack 20 stops moving, and the gear 40 continues to mesh with the second arc-shaped rack 30. The second arc-shaped rack 30 moves relative to the first arc-shaped rack 20, causing the air guide plate 10 to rotate to a horizontal state for airflow.

[0094] Optionally, the length of the toothless portion 26 is greater than or equal to the effective length of the first tooth portion 21.

[0095] like Figure 5As shown, the effective length of the toothless portion 26 on the first arc-shaped rack 20 is greater than the effective length of the first toothed portion 21. This results in the following motion trajectory for the air guide plate 10 as it extends to the intermediate position. During the process of the air guide plate 10 extending from the closed state to the intermediate position, two motion processes occur: When the air guide plate 10 is in the closed state, the gear 40 is located at the effective starting end of the first toothed portion 21 and the second toothed portion 31. The gear 40 simultaneously meshes with both the first toothed portion 21 and the second toothed portion 31, driving the air guide plate 10 to extend to the inclined position; when the air guide plate 10 is in the inclined position, the gear 40 meshes with the end of the first toothed portion 21, approximately meshing with the toothless portion 26, while simultaneously maintaining mesh with the second toothed portion 31, driving only the second arc-shaped rack 30 to move. During the process where the gear 40 only meshes with the second toothed portion 31, the first arc-shaped rack 20, under its own gravity, still moves synchronously with the second arc-shaped rack 30.

[0096] During the retraction of the air guide plate 10 from the air intake position, the gear 40 first drives the second arc-shaped rack 30 to move. Then, through the aforementioned limiting structure, the second arc-shaped rack 30 drives the first arc-shaped rack 20 to move. In this process, by extending the length of the toothless portion 26, the gear 40 is prevented from engaging with the first toothed portion 21 prematurely. This allows the first arc-shaped rack 20 sufficient space to adjust the position of its teeth, ensuring that its teeth correspond to the teeth of the second arc-shaped rack 30 in a preset position, preventing misalignment.

[0097] Optionally, the aforementioned air guiding mechanism is disposed within the housing, which is fixed to the side of the air conditioner. The first arc-shaped rack 20 and the second arc-shaped rack 30 are slidably disposed within the housing. A first slider 24 is disposed on the side of the first arc-shaped rack 20, and a second slider 35 is disposed on the side of the second arc-shaped rack 30. Slide grooves are provided on both sides of the housing, and the first slider 24 and the second slider 35 are respectively slidably disposed within the slide grooves.

[0098] By setting a sliding groove inside the housing, the movement direction of the first arc-shaped rack 20 and the second arc-shaped rack 30 under the transmission of the gear 40 is further defined, so that the first arc-shaped rack 20 and the second arc-shaped rack 30 can first drive the air guide plate 10 to the middle position according to the preset path, and then the second arc-shaped rack 30 slides under the joint limitation of the sliding groove of the housing and the sliding cavity 23 of the first arc-shaped rack 20, driving the air guide plate 10 to rotate to a horizontal state.
