Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an air outlet structure, a ducted air conditioner, and an air conditioner. Background Technology

[0002] As a highly efficient air conditioning device, ducted air conditioners are widely used in various scenarios such as homes, offices, and commercial spaces. They deliver treated air to different areas through ducts, achieving precise control of indoor temperature, humidity, and air quality.

[0003] At the air outlet of a ducted air conditioner, the air guide vane is a crucial component for adjusting the airflow direction. When the air guide vane is in a fixed position to meet the preset airflow direction, the combined effect of its own weight and the outlet air pressure causes a significant load on the vane's rotating shaft. This results in noticeable vibration of the air guide vane. This vibration not only generates noise but, more seriously, leads to unstable airflow, affecting the air conditioner's air delivery efficiency and user experience. Furthermore, the continuous vibration of the air guide vane accelerates structural wear at the shaft connection point. Utility Model Content

[0004] This application provides an air outlet structure, a ducted air conditioner, and an air conditioner to solve the problems of easy vibration of the air guide plate, poor air outlet stability, and severe wear of the equipment at the rotating shaft.

[0005] In a first aspect, some embodiments of this application provide an air outlet structure, including a housing, an air guide plate, and a hinge shaft. An air outlet cavity is provided within the housing, and the air outlet cavity has a first air outlet and a second air outlet, located at adjacent sidewalls of the housing. The air guide plate is hinged to the housing via at least one hinge shaft. The air guide plate is configured to have a first adjustment state, a second adjustment state, and a third adjustment state. In the first adjustment state, the air guide plate closes the first air outlet; in the second adjustment state, the air guide plate closes the second air outlet; and in the third adjustment state, the air guide plate opens a portion of the first air outlet and a portion of the second air outlet. Along the axial direction of the hinge shaft, the hinge shaft is configured to have a first position state and a second position state with sliding adjustment. At least when the air guide plate is in the third adjustment state, the hinge shaft is in the second position state. When the hinge shaft is in the first position state, the air guide plate is rotatably disposed from the housing. When the hinge shaft is in the second position state, rotation of the air guide plate relative to the housing is prevented.

[0006] In one alternative embodiment, the hinge shaft includes a rotating section, a limiting section, and a transmission section connected in sequence. The transmission section is connected to one of the housing and the air guide plate, and the diameter of the transmission section is larger than the diameter of the rotating section.

[0007] When the hinge shaft is in the first position, the other of the housing and the air guide plate is rotatably set with the rotating section.

[0008] When the hinge shaft is in the second position, the other of the housing and the air guide plate is interference-fitted or limit-fitted with the limiting section and / or the transmission section to prevent the air guide plate from rotating relative to the housing.

[0009] In one alternative embodiment, the limiting section is a frustum structure, and along the axial direction of the hinge shaft, the diameter of the limiting section near the transmission section is larger.

[0010] In one alternative implementation, the diameter of the transmission section is equal to the maximum diameter of the limiting section.

[0011] In one alternative embodiment, the end of the transmission section away from the rotating section along the axial direction is provided with a spline structure, a flat key structure, or a semi-circular key structure.

[0012] In one alternative embodiment, the transmission section is provided with a spline structure, a flat key structure, or a semi-circular key structure, and the air guide plate is provided with a matching transmission part corresponding to the transmission section.

[0013] In an optional embodiment, the air outlet structure further includes a drive member, the output end of which is connected to the hinge shaft for controlling the hinge shaft to switch between a first position state and a second position state.

[0014] In one optional embodiment, the number of hinge shafts is at least two, and the at least two hinge shafts are spaced apart along the length of the air guide plate. The number of driving members is at least two, and one driving member is connected to one end of each hinge shaft along the axial direction.

[0015] In one optional embodiment, the number of driving elements and the number of hinge shafts are two. The air outlet structure also includes a transmission rod located between and connected to the two hinge shafts along the axial direction of the hinge shafts. Driving elements are respectively arranged on the two sides of the two hinge shafts that are far apart from each other.

[0016] One drive unit is used to control the two hinge axes to move from a first position state to a second position state, and the other drive unit is used to control the two hinge axes to move from the second position state to the first position state.

[0017] In an optional embodiment, the housing includes a partition located between a first air outlet and a second air outlet to separate the first air outlet and the second air outlet, and the air guide plate is hinged to the partition via a hinge shaft.

[0018] In one optional embodiment, the air guide plate has a hinge groove at one end along the width direction; along the length direction of the air guide plate, the air guide plate has insertion through holes on opposite sides of the hinge groove, the insertion through holes being used to insert an adapter hinge shaft.

[0019] In one alternative embodiment, the housing is provided with a retaining seat, and the retaining seat is provided with a limiting groove corresponding to the hinge shaft, the opening width of the limiting groove being smaller than the diameter of the hinge shaft.

[0020] Secondly, some embodiments of this application provide a ducted air conditioner, including the air outlet structure, heat exchanger, and fan mentioned in the first aspect. The heat exchanger and fan are located inside the housing, and the fan is used to drive air to flow through the heat exchanger and be blown out from at least one of the first air outlet and the second air outlet.

[0021] Thirdly, some embodiments of this application provide an air conditioner, including the ducted air conditioner of the second aspect.

[0022] The technical solutions provided by the embodiments of this application may include the following beneficial effects:

[0023] The first position of the hinge shaft refers to the state in which the hinge shaft allows the air guide plate to rotate relative to the housing, which can be achieved through a rotatable fit between the hinge shaft and the housing or the air guide plate. The second position of the hinge shaft refers to the state in which the hinge shaft prevents the air guide plate from rotating through an interference fit or a limiting structure. For example, the hinge shaft may slide axially to adjust its position and then engage with a limiting component or be in a compressed interference fit state.

[0024] With the above-described air outlet configuration, when unidirectional airflow is required, the hinge shaft is in the first position, and the guide vane can rotate around the shaft to close either the first or second air outlet. When bidirectional airflow is required, the guide vane adjusts to the third adjustment state, and the hinge shaft moves to the second position, creating an interference or limiting fit between the hinge shaft, the housing, and the guide vane. This reduces or eliminates the shaking and vibration of the guide vane caused by wind pressure and gravity at the hinge shaft. In other words, the hinge shaft can be adjusted axially along the first and second positions via automatic control or manual adjustment to trigger the locking mechanism in dual-outlet mode.

[0025] Thus, this application, by switching the axial position of the hinge shaft, maintains the flexibility of the air guide plate adjustment while adding a locking function, solving the stability problem of the air guide plate in dual-outlet mode. This allows the air guide plate to maintain stable operation in various air supply modes. In particular, in dual-outlet mode, the locking of the hinge shaft effectively suppresses vibration, ensuring uniform airflow and precise airflow control. It can also significantly reduce or avoid equipment vibration and wear at the hinge shaft, thereby improving the stability and service life of the entire machine. Attached Figure Description

[0056] Please see Figures 1 to 13This application provides an air outlet structure, a ducted air conditioner, and an air conditioner to solve the problems of easy vibration of the air guide plate, poor air outlet stability, and severe wear of the equipment at the rotating shaft.

[0057] On the one hand, such as Figure 1 As shown in the figure, this application embodiment provides a ducted air conditioner 100, which includes an air outlet structure 10, a heat exchanger 20, and a fan 30. The air outlet structure 10 includes a housing 11, within which are an air inlet chamber 111 and an air outlet chamber 112. The air inlet chamber 111 has an air inlet 113, and the air outlet chamber 112 has a first air outlet 114 and a second air outlet 115, located at two adjacent side walls of the housing 11. The heat exchanger 20 is located within the air outlet chamber 112, and the fan 30 is located within the air inlet chamber 111. The rotation of the fan 30 drives air to flow through the heat exchanger 20 and be blown out through at least one of the first air outlet 114 and the second air outlet 115.

[0058] Alternatively, the housing 11 of the air outlet structure 10 may also include an air outlet cavity 112. When applied to the duct air conditioner 100, both the heat exchanger 20 and the fan 30 are disposed within the housing 11. The rotation of the fan 30 drives air to flow through the heat exchanger 20 and be blown out from at least one of the first air outlet 114 and the second air outlet 115.

[0059] The heat exchanger 20 is a component used to regulate the temperature or humidity of air. Taking a finned structure as an example, the heat exchanger 20 arranged in the air outlet cavity 112 can cool or heat the flowing air to regulate its temperature and humidity. The fan 30 located in the air inlet cavity 111 can drive the airflow. For example, the fan 30 can be a centrifugal fan or an axial fan. By rotating the fan 30, the air is driven to flow from the air inlet 113 through the air inlet cavity 111 and the air outlet cavity 112 in sequence. The air can be heated or cooled by the heat exchanger 20 in the air outlet cavity 112. Then the air can be blown out through at least one of the first air outlet 114 and the second air outlet 115 to regulate the temperature and humidity.

[0060] To adjust the direction of airflow, such as Figure 2 , Figure 3 and Figure 4 As shown, the air outlet structure 10 also includes an air guide plate 12 and a hinge shaft 13. The air guide plate 12 is hinged to the housing 11 via at least one hinge shaft 13, and the air guide plate 12 is configured to have at least three position states, such as a first adjustment state, a second adjustment state, and a third adjustment state.

[0061] Taking the example of a first air outlet 114 located on the front side wall of the housing 11 and a second air outlet 115 located on the lower side wall of the housing 11, the first air outlet 114 is a horizontal air outlet, and the second air outlet 115 is a vertical air outlet.

[0062] like Figure 5 As shown, in the first adjustment state, the air guide plate 12 closes the first air outlet 114, so that the air in the air outlet cavity 112 can be blown downwards through the second air outlet 115. Figure 6 As shown, in the second adjustment state, the air guide plate 12 closes the second air outlet 115, so that the air in the air outlet cavity 112 can be blown forward from the first air outlet 114. Figure 7 As shown, in the third adjustment state, the air guide plate 12 partially opens the first air outlet 114 and partially opens the second air outlet 115, so that some air in the air outlet cavity 112 can be blown forward through the first air outlet 114, and the other part of the air can be blown downward through the second air outlet 115. By adjusting the air guide plate 12 to different positions, the air outlet angle and air outlet direction can be flexibly controlled.

[0063] When the air guide plate 12 is in the first adjustment state and the second adjustment state, the side wall of the air guide plate 12 can contact and be supported with the edges of the first air outlet 114 and the second air outlet 115, so that the air guide plate 12 bears a small force at the hinge shaft 13.

[0064] However, when the air guide plate 12 is in the third adjustment state, it is only supported and connected to the housing 11 through the hinge shaft 13, and can be regarded as being in a suspended state. At this time, the air guide plate 12 in the inclined position has a large force at the hinge shaft 13 under the combined action of its own weight and the air pressure.

[0065] Based on this, along the axial direction of the hinge shaft 13, the hinge shaft 13 is configured to have a first position state and a second position state with sliding adjustment. For example... Figure 3 As shown, when the hinge shaft 13 is in the first position, the air guide plate 12 and the housing 11 are rotatably configured to allow the air guide plate 12 to rotate and switch between the first adjustment state, the second adjustment state, and the third adjustment state. Figure 7 As shown, when the hinge shaft 13 is in the second position, it prevents the air guide plate 12 from rotating relative to the housing 11. Furthermore, at least when the air guide plate 12 is in the third adjustment state, the hinge shaft 13 is in the second position to lock the air guide plate 12.

[0066] In other words, the first position state of the hinge shaft 13 refers to the state in which the hinge shaft 13 allows the air guide plate 12 to rotate relative to the housing 11, which can be achieved through a rotatable fit between the hinge shaft 13 and the housing 11 or the air guide plate 12. The second position state refers to the state in which the hinge shaft 13 prevents the air guide plate 12 from rotating through an interference fit or a limiting structure. For example, the hinge shaft 13 may slide axially to adjust its position and then engage with a limiting component or be in a compressed interference fit state.

[0067] With the above-described configuration of the air outlet structure 10, when unidirectional airflow is required, the hinge shaft 13 is in the first position, and the air guide plate 12 can rotate around the shaft to close the first air outlet 114 or the second air outlet 115. When bidirectional airflow is required, the air guide plate 12 adjusts to the third adjustment state, and the hinge shaft 13 moves to the second position, so that the hinge shaft 13 forms an interference fit or a limiting fit with the housing 11 and the air guide plate 12, thereby reducing or eliminating the shaking and vibration of the air guide plate 12 caused by wind pressure and gravity at the hinge shaft 13. In other words, the hinge shaft 13 can be adjusted axially along the first and second position states through automatic control or manual adjustment to trigger the locking mechanism in dual-airflow mode.

[0068] Thus, by switching the axial position of the hinge shaft 13, this application maintains the adjustment flexibility of the air guide plate 12 while adding a locking function, solving the stability problem of the air guide plate 12 in the dual-outlet mode. This allows the air guide plate 12 to maintain stable operation in various air supply modes. In particular, in the dual-outlet mode, the locking of the hinge shaft 13 effectively suppresses vibration, ensuring uniform airflow and precise airflow control. It can also significantly reduce or avoid equipment vibration and wear at the hinge shaft 13, thereby improving the stability and service life of the entire machine.

[0069] It should be noted that the air outlet structure 10 provided in this application embodiment can be applied to the duct air conditioner 100, as well as to indoor wall-mounted air conditioners or other equipment structures with bidirectional or multidirectional air outlets, and is not limited thereto.

[0070] To achieve the function of adjusting and switching between the first and second position states of the hinge shaft 13 along the axial direction. For example... Figure 8As shown, the hinge shaft 13 includes a rotating section 131, a limiting section 132, and a transmission section 133 connected in sequence. The transmission section 133 is drively connected to one of the housing 11 and the air guide plate 12, and the diameter of the transmission section 133 is larger than the diameter of the rotating section 131. When the hinge shaft 13 is in the first position, the other of the housing 11 and the air guide plate 12 is rotatably connected to the rotating section 131. When the hinge shaft 13 is in the second position, the other of the housing 11 and the air guide plate 12 is interference-fitted or limited-fitted with the limiting section 132 and / or the transmission section 133 to prevent the air guide plate 12 from rotating relative to the housing 11.

[0071] Taking the transmission section and the air guide plate 12 as an example, during the process of the air guide plate 12 rotating to switch between the first adjustment state, the second adjustment state, and the third adjustment state, the air guide plate 12 will drive the hinge shaft 13 to rotate synchronously, that is, there will be no relative rotation between the two. When the hinge shaft 13 is in the first position state, the housing 11 and the rotating section 131 are rotatably configured. When the hinge shaft 13 is in the second position state, the housing 11 is interference-fitted or limit-fitted with at least one of the limiting section 132 and the transmission section 133 to prevent the air guide plate 12 from rotating relative to the housing 11.

[0072] The rotating section 131 refers to the cylindrical structure in the hinge shaft 13 used to achieve the rotational action. Specifically, it can be made of a smooth and wear-resistant metal shaft or high-strength plastic. The transmission section 133 refers to the connecting structure used to transmit driving force. Specifically, it can be a shaft section with a keyway, such as the air guide plate 12, which can drive the hinge shaft 13 to rotate synchronously through the transmission section 133. Since the diameter of the transmission section 133 is larger than the diameter of the rotating section 131, a limiting section 132 can be used for transition connection between the transmission section 133 and the rotating section 131. Thus, when the hinge shaft 13 is in the first position, the transmission section 133 is connected to the air guide plate 12, and the rotating section 131 is clearance-fitted with the housing 11. At this time, the air guide plate 12 can rotate relative to the housing 11 around the axis of the hinge shaft 13. When it is necessary to fix the position of the air guide plate 12, the hinge shaft 13 can be pushed to move to the second position, so that the limiting section 132 or the transmission section 133 is in an interference fit or a limiting fit with the housing 11, thereby limiting the rotation or vibration of the air guide plate 12 relative to the housing 11. At the same time, the resistance of the hinge shaft 13 in the second position can reduce the force at the air guide plate 12 rotation drive device, which helps to improve the stability of the drive equipment and the whole machine.

[0073] Through the above technical solution, this application, while maintaining the rotation adjustment function of the air guide plate 12, adds an axial movement locking mechanism (i.e., a three-section hinge shaft 13). In the dual-air outlet working mode, the vibration of the air guide plate 12 is eliminated by mechanical limiting, ensuring the stability of the air outlet direction. When it is necessary to switch the air outlet mode (i.e., air outlet direction and air outlet angle), it is only necessary to control the axial movement of the hinge shaft 13 to the first position state to quickly release the lock, realizing a smooth and reliable switching between different air outlet states.

[0074] The limiting segment 132 can be configured as a frustum structure, with a larger diameter near the transmission segment 133 along the axial direction of the hinge shaft 13. By configuring the limiting segment 132 as a frustum structure, the transmission segment 133 and the rotating segment 131, which have different diameters, can smoothly transition through the frustum-structured limiting segment 132, facilitating a smooth switching of the hinge shaft between the first and second states. This avoids the stepped shaft structure between the rotating segment 131 and the transmission segment 133 affecting the hinge shaft 13's entry into the second position.

[0075] Therefore, the diameter of the transmission section 133 is equal to the maximum diameter of the limiting section 132. This allows the housing 11 to have either an interference fit or a limiting fit with the limiting section 132 when the hinge shaft 13 is in the second position. Alternatively, the housing 11 can have either an interference fit or a limiting fit with the transmission section 133. The choice can be made flexibly as needed, and no limitation is imposed.

[0076] To ensure proper transmission between the hinge shaft 13 and the air guide plate 12 at the transmission section 133, such as... Figures 8-10 As shown, the transmission section 133 is provided with a spline structure, a flat key structure, or a semi-circular key structure at one end along the axial direction away from the rotation section 131.

[0077] The transmission section 133 is provided with one of the following structures: spline structure, flat key structure, and semi-circular key structure. This means that the surface of the shaft section is provided with mechanical transmission connection features. Specifically, it can be achieved by a structure of protrusions and grooves evenly distributed along the circumference, and the rotational torque is transmitted through key connection.

[0078] Taking the hinge shaft 13 in the first position state as a transmission connection with the air guide plate 12, by setting one of the spline structure, flat key structure and semi-circular key structure in the transmission section 133, and by providing a matching transmission part for the air guide plate 12 in the corresponding transmission section 133, reliable torque transmission can be achieved, thereby avoiding the risk of slippage during the rotation of the air guide plate 12.

[0079] In some embodiments, such as Figure 6 and Figure 8As shown, the housing 11 includes a separator 116, which is located between the first air outlet 114 and the second air outlet 115 to separate the first air outlet 114 and the second air outlet 115. The air guide plate 12 is hinged to the separator 116 via a hinge shaft 13.

[0080] The separator 116 refers to the isolation component provided at the air outlet of the housing 11 to divide different air outlet areas. Specifically, the Gree structure between the first air outlet 114 and the second air outlet 115 can be considered the separator 116. By hingedly installing the air guide plate 12 at the separator 116, taking the planes of the first and second air outlets being perpendicular to each other as an example, rotating the air guide plate 12 90° clockwise can switch from a second adjustment state to a first adjustment state to close the first air outlet 114. Alternatively, the air guide plate 12 can also be rotated 45° clockwise from the second adjustment state to a third adjustment state. This facilitates flexible switching of the air guide plate 12 between multiple states.

[0081] It should be noted that the third adjustment state of the air guide plate 12 is not a fixed angle position. The air guide plate 12 is in the third adjustment state when both the first air outlet 114 and the second air outlet 115 are kept open. To increase the airflow from the first air outlet 114, the air guide plate 12 can be rotated towards the second air outlet 115. To increase the airflow from the second air outlet 115, the air guide plate 12 can be rotated towards the first air outlet 114.

[0082] like Figure 8 and Figure 10 As shown, the air guide plate 12 has a hinge groove 121 at one end along the width direction. Along the length direction of the air guide plate 12, the air guide plate 12 has insertion through holes 122 on opposite sides of the hinge groove 121. The insertion through holes 122 are used to insert the fitting hinge shaft 13.

[0083] Reference Figure 10 Taking the transmission section 133 of the hinge shaft 13 and the air guide plate 12 as an example of transmission adaptation. Along the axial direction of the insertion through hole 122, the two insertion through holes 122 on both sides of the same hinge groove 121 have different diameters. One of the insertion through holes 122 with a smaller diameter is used to insert the end of the adapter rotating section 131 away from the transmission section 133, and the other insertion through hole 122 with a larger diameter is provided with a spline structure, a flat key structure or a semi-circular key structure, for inserting the adapter transmission section 133 to prevent relative rotation between the air guide plate 12 and the hinge shaft 13.

[0084] By restraining the hinge groove 121 at one end of the air guide plate 12 in the width direction, and providing insertion through holes 122 adapted to the hinge shaft 13 on both sides of the hinge groove 121, the hinge shaft 13 adapted to the air guide plate 12 is located in the hinge groove 121, thereby avoiding the protrusion and exposure of the hinge shaft 13.

[0085] Correspondingly, such as Figure 8 As shown, the housing 11 is provided with a card holder 117, and the card holder 117 is provided with a limiting groove 118 corresponding to the hinge shaft 13. The opening width of the limiting groove 118 is smaller than the diameter of the hinge shaft 13.

[0086] Reference Figure 8 and Figure 10 The limiting groove 118 is used to accommodate the rotating section 131 of the hinge shaft 13. If the limiting groove 118 is a circular groove opening radially on one side, the diameter of the limiting groove 118 is larger than the diameter of the rotating section 131, and the width of the opening of the limiting groove 118 is smaller than the diameter of the rotating section 131, facilitating the insertion of the rotating section 131 into the limiting groove 118 radially. The smaller opening width of the limiting groove 118 prevents the rotating section 131 from disengaging radially from the limiting groove 118 and allows the rotating section 131 to rotate smoothly relative to the mounting base 117.

[0087] Continue to refer to Figure 8 and Figure 10 When the hinge shaft 13 moves from the first position to the second position, the limiting section 132 and the transmission section 133 move axially toward the limiting groove 118 until the limiting section 132 and the inner wall of the limiting groove 118 are in interference fit (i.e., the maximum diameter of the limiting section 132 is greater than the diameter of the limiting groove 118), or the transmission section 133 and the inner wall of the limiting groove 118 are in interference fit (i.e., the diameter of the transmission section 133 is greater than the diameter of the limiting groove 118). This interference fit between the hinge shaft 13 and the limiting groove 118 prevents the hinge shaft 13 from rotating relative to the mounting base 117 and the housing 11, ensuring that the air guide plate 12 remains stable under high airflow conditions, improving airflow uniformity and user experience.

[0088] To improve the switching speed of the hinge shaft 13 between the first and second position states. For example... Figure 11 and Figure 12 As shown, the air outlet structure 10 also includes a drive member 14, the output end of which is connected to the hinge shaft 13 and is used to control the hinge shaft 13 to switch between a first position state and a second position state.

[0089] The driving component 14 refers to a power device capable of outputting linear or rotary motion. For example, the power structure of the driving component 14 can be a linear motor, a rotary motor, or a cylinder, used to drive the hinge shaft 13 to move axially to achieve the switching of position states.

[0090] Taking the ability of the drive member 14 to output linear motion as an example, the output end of the drive member 14 is connected axially to one end of the hinge shaft 13. The two are fixedly connected so that the drive member 14 can drive the hinge shaft 13 to reciprocate axially between a first position and a second position.

[0091] Alternatively, the drive unit 14 outputs rotational motion. For example, the drive unit 14 includes a rotary motor and a crank wheel, positioned along the axial direction of the hinge shaft 13, with the crank wheel near one end of the hinge shaft 13, so that the rotary motor can drive the crank wheel to rotate in a plane parallel to the axial direction of the hinge shaft 13. Since the edge of the crank wheel has different distances from the axial direction of the rotary motor, by controlling the rotary motor to rotate to a suitable angle, the crank wheel can abut against the hinge shaft 13 and push the hinge shaft 13 from a first position state (or a second position state) to a second position state (or a first position state).

[0092] Thus, when the air guide plate 12 needs to be switched to the third adjustment state, the drive member 14 drives the hinge shaft 13 to move to the second position state, so that the transmission section 133 (or the limiting section 132) of the hinge shaft 13 is interference-fitted with the limiting groove 118. At this time, the air guide plate 12 cannot rotate around the shaft, maintaining a stable state in which the first air outlet 114 and the second air outlet 115 are simultaneously open. When it is necessary to adjust the air guide plate 12 to the first adjustment state or the second adjustment state, the holding force of the drive member 14 can be driven or removed to move the hinge shaft 13 to the first position state. At this time, the rotation section 131 of the hinge shaft 13 is rotatably engaged with the limiting groove 118, and the air guide plate 12 can rotate around the shaft to close the corresponding air outlet. That is, the drive member 14 can realize the automatic switching of the hinge shaft 13 between the first position state and the second position state, improving the reliability and response efficiency of the air outlet direction switching.

[0093] For example, such as Figures 11-13 As shown, there are at least two hinge shafts 13, which are spaced apart along the length of the air guide plate 12. Correspondingly, there are at least two drive members 14, with one drive member 14 connected to one end of each hinge shaft 13 along the axial direction.

[0094] Correspondingly, there are at least two card holders 117, each card holder 117 is adapted to a hinge shaft so that each hinge shaft 13 is inserted into a limiting groove 118.

[0095] By configuring at least two spaced-apart hinge shafts 13 along the length of the air guide plate 12, the local stress on the air guide plate 12 can be distributed by increasing the number of support points, thus avoiding large forces at a single support point. This helps improve the stability of the hinge structure between the air guide plate 12 and the housing 11, and improves the overall durability and service life of the machine.

[0096] By connecting a drive element 14 to each hinge axis 13, each hinge axis 13 can automatically switch between a first position state and a second position state. This provides a faster response speed and improves the switching speed of the air guide plate 12 between multiple adjustment states. Specifically, the drive element 14 connected to each hinge axis 13 can move the hinge axis 13 either towards the first position state or towards the second position state, offering flexible and convenient control.

[0097] Taking the power structure of the drive unit 14 as a rotary motor as an example, although the crank wheel can abut against one end of the hinge shaft 13, so that the rotation of the rotary motor can push the hinge shaft 13 from the first position state to the second position state, the drive unit 14 has difficulty pulling the hinge shaft 13 back from the second position state to the first position state.

[0098] At this time, a drive member 14 can be provided at both ends of the same hinge shaft 13, so that one drive member 14 can push the hinge shaft 13 from the first position state to the second position state, and the other drive member 14 can push the hinge shaft 13 from the second position state to the first position state.

[0099] Or, such as Figure 9 and Figure 12 As shown, there are two hinge shafts 13 and two driving members 14. The air outlet structure 10 also includes a transmission rod 15, which is located between and connected to the two hinge shafts 13 along the axial direction of the hinge shafts 13. Driving members 14 are respectively arranged on the two sides of the two hinge shafts that are far apart from each other. One driving member 14 is used to control the two hinge shafts 13 to move from a first position state to a second position state, and the other driving member 14 is used to control the two hinge shafts 13 to move from the second position state to the first position state.

[0100] The transmission rod 15 refers to the rigid connecting component that connects the two hinge shafts 13. It can be made of metal or high-strength plastic and its function is to enable the two hinge shafts to form a linkage structure. The transmission rod 15 between the two hinge shafts 13 can be connected by means of bonding, welding, snap-fitting, plugging, or heat fusion.

[0101] The position setting of the drive unit 14 refers to the two drive units 14 being arranged on the outer sides of the two ends of the hinge shaft 13 in the axial direction, so as to realize bidirectional independent drive control.

[0102] In this design, the number of hinge shafts 13 can be three or even more, simply by connecting a transmission rod 15 between two axially adjacent hinge shafts 13. Two drive members 14 are arranged on the outer sides of both ends of the hinge shafts 13.

[0103] For example, the connection of the transmission rod 15 ensures that the two hinge shafts 13 remain synchronized during axial movement. When it is necessary to lock the position of the air guide plate 12, the drive member 14 on the left pushes the hinge shaft 13 to move axially to the right, and the transmission rod 15 drives the right hinge shaft 13 to move synchronously to the second position. When it is necessary to unlock, the right drive member 14 applies a reverse force to reset the hinge shaft 13 to the left to the first position. This solution, through the symmetrical arrangement of the two drive members 14 and the intermediate transmission rod 15, forms a bidirectional symmetrical drive mode for driving two or more hinge shafts 13 to switch axial movement.

[0104] On the other hand, this application embodiment also provides an air conditioner, including the ducted air conditioner 100 described above. Since this air conditioner includes the ducted air conditioner 100 described above, it possesses all the effects of the aforementioned ducted air conditioner 100, thus solving the problems of easy vibration of the air guide plate, poor airflow stability, and severe wear at the rotating shaft.
