Technical Field

[0001] This utility model relates to the field of duct air conditioning technology, and more specifically, to a duct air conditioning machine. Background Technology

[0081] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0082] like Figures 1 to 8 As shown, an embodiment of this utility model provides a ducted air conditioner, which includes a housing 10 and an air guiding structure 50. The bottom of the housing 10 is provided with a first air outlet 11. The air guiding structure 50 includes an air duct frame 51 and an air guide plate 52. The air duct frame 51 forms a connecting opening 511 that communicates with the first air outlet 11. The air guide plate 52 is rotatably disposed at the connecting opening 511. At least a portion of the air duct frame 51 is vertically and vertically disposed on the housing 10 so that the position of the air duct frame 51 is adapted to the position of the ceiling at the installation location of the ducted air conditioner.

[0083] The ducted air conditioner provided in this embodiment, by flexibly and height-adjustably mounting the duct frame 51 at the housing 10, allows for adjustable height of the connecting port 511 relative to the first air outlet 11. This effectively adjusts the height of the connecting port 511, ensuring it aligns with the ceiling height and preventing air leakage due to a large gap between the connecting port 511 and the ceiling. This guarantees effective airflow and allows for better vertical airflow into the room. Therefore, the technical solution provided by this invention solves the problem in existing ducted air conditioners where the air outlet is fixed, resulting in a large gap between the air outlet and the ceiling and causing air leakage.

[0084] Specifically, "the position of the duct frame 51 is adapted to the position of the ceiling at the installation location of the duct unit" can be understood as the bottom of the duct frame 51 being flush with the bottom of the ceiling to avoid a large installation gap due to height difference. Specifically, "flush" here can be understood as the heights being completely equal or the height difference being within a small range, which can be 0-15mm.

[0085] Specifically, the air guiding structure also includes a decorative frame 53, which is installed at the bottom of the duct frame. The decorative frame 53 is positioned to avoid the connecting opening and is adapted to fit the ceiling. The height-adjustable design of the duct frame 51 allows the air outlet component (also known as the air guiding structure 50) to adapt to ceilings of different thicknesses, improving installation convenience and compatibility. In principle, by adjusting the height of the duct frame 51, the bottom of the duct frame 51 can be flush with the ceiling, ensuring a smaller installation gap between the duct frame 51 and the ceiling, thereby reducing air leakage. Furthermore, by changing the distance between the air guide plate 52 and the ceiling, the air delivery effect can be optimized. In terms of effectiveness, this design not only simplifies the installation process but also ensures the aesthetics and performance of the duct unit. In other embodiments, the duct frame 51 can be raised and lowered using a flexible telescopic mechanism or a manual adjustment device to adapt to specific installation conditions or user preferences.

[0086] In this embodiment, at least a portion of the duct frame 51 extends along a preset direction and rises and falls along the preset direction. At least a portion of the duct frame 51 is embedded in the connecting opening 511 or sleeved on the outside of the connecting opening 511. And / or, the duct machine further includes a lifting drive device, which includes a lifting rod and a drive member. The lifting rod is connected to the duct frame, and the drive member is movably disposed. The drive member is connected to the lifting rod to drive the lifting rod to be disposed in a way that allows it to rise and fall.

[0087] Specifically, the lifting mechanism of the duct frame 51, in conjunction with the lifting drive device 60, achieves automated height adjustment, improving operational convenience and intelligence. In principle, the embedded or sleeved arrangement of the duct frame 51 facilitates effective guidance and control during lifting, enhancing stability. Furthermore, the lifting drive device 60, through the movement of the drive component 62, converts the movement of the lifting rod 61 into vertical movement, thereby driving the duct frame 51 to rise and fall, further improving its lifting stability. In terms of effectiveness, this design ensures optimal performance of the duct unit in various installation environments, while also facilitating later maintenance and cleaning. In other embodiments, the lifting drive device 60 can employ alternatives such as electric actuators, hydraulic cylinders, or pneumatic cylinders to adapt to different working pressure and speed requirements.

[0088] In this embodiment, the duct frame 51 includes an outer frame 512 and an inner frame 513. The inner frame 513 is embedded within the outer frame 512, and the outer frame 512 is installed within the communication port 511. The inner frame 513 is vertically detachable from the outer frame 512. Alternatively, the side of the inner frame 513 closest to the first air outlet 11 is chamfered. Specifically, the fitted inner frame 513 and outer frame 512 facilitates the effective guidance of the inner frame 513's movement stability, ensuring stable movement. The chamfered treatment of the inner frame 513 helps improve airflow distribution, reduce wind resistance, and increase air delivery efficiency. In terms of effectiveness, this design not only enhances the adaptability of the duct unit but also improves air delivery quality and enhances the user experience. In other embodiments, the airflow performance can be further optimized by changing the shape or material of the inner frame 513 or by adding guide vanes to the inner frame 513, but this may increase manufacturing costs and installation difficulty.

[0089] Specifically, both the inner frame 513 and the outer frame 512 extend along a preset direction, and the inner frame 513 rises and falls along the preset direction. In this way, the interlocking arrangement facilitates the effective guidance of the movement of the inner frame 513, thereby improving the stability of the lifting and lowering movement.

[0090] In this embodiment, there are at least two air guide plates 52, which are arranged along the extension direction of the housing 10. The air guide structure 50 has a first air guide state, a second air guide state, and a third air guide state. The connecting port 511 has a first air outlet edge 5111 and a second air outlet edge 5112 that are opposite to each other and spaced apart. When the air guide structure 50 is in the first air guide state, at least two air guide plates 52 discharge air towards the side away from the second air outlet edge 5112. When the air guide structure 50 is in the second air guide state, at least two air guide plates 52 discharge air towards the side closer to the second air outlet edge 5112. When the air guide structure 50 is in the third air guide state, one of the at least two air guide plates 52 discharges air towards the side closer to the first air outlet edge 5111, and the other of the at least two air guide plates 52 discharges air towards the side closer to the second air outlet edge 5112. By setting multiple air guide vanes 52 and different air guiding states, diversified control of airflow direction can be achieved to meet the air supply needs of different spaces. In principle, the rotation angle of the air guide vanes 52 is controlled by a motor. By changing the arrangement of the air guide vanes 52, the direction and intensity of the airflow can be adjusted. In terms of effect, this design can provide a more personalized and efficient air supply solution, enhancing the practicality and comfort of the air conditioning. In other embodiments, more complex airflow adjustment strategies can be achieved by increasing the number of air guide vanes 52 or by using a programmable motor control system.

[0091] Specifically, the housing 10 has a side portion located between the top and the bottom of the housing 10, and a second air outlet 12 is provided on the side portion. The first air outlet 11 and the second air outlet 12 are spaced apart along the extending direction of the housing 10. The first air outlet edge 5111 is located on the side of the second air outlet edge 5112 away from the second air outlet 12. The second air outlet 12 can be selectively opened or closed. When the second air outlet 12 is open and the air guiding structure 50 is in the third air guiding state, at least one of the two air guiding plates 52 away from the second air outlet 12 discharges air toward the side closer to the first air outlet edge 5111, and at least one of the two air guiding plates 52 near the second air outlet 12 discharges air toward the side closer to the second air outlet edge 5112. This allows for the combination of the air outlet methods of the first air outlet 11 and the second air outlet 12, ensuring that air is directed in two different directions through the first air outlet 11 and the second air outlet 12. Furthermore, in the third airflow guiding state, the air outlet near the first air outlet edge 5111 is only downward airflow, corresponding to airflow towards the first area; the air outlet near the second air outlet edge 5112 is downward airflow through both the second air outlet 12 and the first air outlet 11, corresponding to airflow towards the second area. This configuration is suitable when the heat or cooling demand of the second area is greater than that of the first area.

[0092] Specifically, the ducted air conditioner includes a housing 10 and an air distribution plate 20. The housing 10 is provided with a first air outlet and a second air outlet. The housing 10 has a top and a bottom that are disposed opposite to each other. The first air outlet is disposed at the bottom, and the second air outlet is disposed on the side between the top and the bottom. The air distribution plate 20 is movably disposed within the housing 10. The air distribution plate 20 has a first open position, a second open position, and an intermediate open position located between the first open position and the second open position. When the air distribution plate 20 is in the first open position, it avoids the first air outlet and blocks the second air outlet. When the air distribution plate 20 is in the second open position, it avoids the second air outlet and blocks the first air outlet. When the air distribution plate 20 is in the intermediate open position, it avoids both the first air outlet and the second air outlet, so that air can be discharged from both the first air outlet and the second air outlet.

[0093] The ducted air conditioner provided in this embodiment features a design that allows the air distributor 20 to switch positions to change the airflow direction. This is achieved through a gear mechanism, which provides precise positioning and control during the movement of the air distributor 20. In principle, the movement of the air distributor 20 is based on gear transmission; a motor drives the gears, which in turn move the air distributor 20 to a predetermined position, thus blocking or opening the air outlet. In terms of effect, the air distributor 20 in this embodiment effectively controls the airflow direction, enabling unidirectional or bidirectional airflow, improving the flexibility and comfort of air conditioning use. In other embodiments, the movement of the air distributor 20 can also be controlled by electromagnetic drive or other structural transmission technologies to adapt to different application scenarios and technical requirements. When the air distribution plate 20 is in the first open position, the air distribution plate 20 is positioned to avoid the first air outlet 11 and to block the second air outlet 12; when the air distribution plate 20 is in the second open position, the air distribution plate 20 is positioned to avoid the second air outlet 12 and to block the first air outlet 11; when the air distribution plate 20 is in the middle open position, the air distribution plate 20 is positioned to avoid the first air outlet 11 and the second air outlet 12, so that air can be discharged from both the first air outlet 11 and the second air outlet 12.

[0094] In this embodiment, the ducted air conditioner further includes an indoor heat exchanger 30; the housing 10 includes a first housing 13 and a second housing 14, the first housing 13 forming a heat exchange chamber 131, and the indoor heat exchanger 30 is disposed within the heat exchange chamber; the second housing 14 is connected to the first housing 13, and the second housing 14 forms a distribution chamber 141, the distribution chamber 141 is located on the air outlet side of the heat exchange chamber 131 and communicates with the heat exchange chamber 131, the first air outlet 11 and the second air outlet 12 are both installed on the second housing 14, and the air distribution plate 20 is rotatably disposed within the distribution chamber 141. By separating the indoor heat exchanger 30 and the distribution chamber 141, heat loss during the heat exchange process can be avoided, improving energy efficiency. In principle, the separate design of the heat exchange chamber 131 and the distribution chamber 141 follows thermodynamic principles, ensuring temperature and flow control of air during heat exchange and distribution. Furthermore, this design avoids the impact of the air distribution plate on the fixed indoor heat exchanger 30, and the separate arrangement ensures stable and precise rotation of the air distribution plate. Specifically, in terms of performance, this design effectively improves the cooling or heating performance of the air conditioner while ensuring uniformity and comfort of the airflow. In other embodiments, the heat exchange chamber and the air distribution chamber can be integrated into a single design, achieving a similar effect by optimizing the internal airflow path, but this may increase manufacturing complexity and cost. Additionally, the above arrangement can also be achieved by adding an air distribution chamber to the casing of a conventional ducted air conditioner, thus facilitating installation.

[0095] Specifically, the ducted air conditioner also includes insulation material 70, which is provided at the periphery of the first air outlet 11 and / or the periphery of the second air outlet 12. The application of insulation material 70 helps reduce the loss of hot and cold air at the corresponding air outlets, improving energy utilization efficiency. Utilizing its low thermal conductivity, insulation material 70 prevents energy exchange caused by temperature differences between the inside and outside, thereby maintaining a stable outlet temperature. In terms of effectiveness, the installation of insulation material 70 can significantly reduce energy consumption and improve user comfort. In other embodiments, the same purpose can be achieved by improving the sealing of the air outlets or using other types of insulation materials, such as advanced insulation materials like aerogel or vacuum insulation panels.

[0096] In this embodiment, the duct unit further includes a drive structure 40, which is drivenly connected to the air distribution plate 20 to move the air distribution plate 20 to the first open position, the second open position, or the intermediate open position. The drive structure 40 employs gear transmission or chain transmission to ensure precise positioning of the air distribution plate 20. In principle, the drive structure 40 converts the rotation of the motor into linear motion, thereby pushing the air distribution plate 20 to move on a predetermined track. In terms of effect, this drive structure enables rapid response and accurate control of the air distribution plate 20, improving the intelligence level of the duct unit. In other embodiments, non-electric power sources such as hydraulic or pneumatic drives can be used to drive the air distribution plate 20 to adapt to the usage requirements of special environments.

[0097] Specifically, the drive structure 40 includes an arc-shaped rack 41, a drive gear 42, and a drive motor 43. The arc-shaped rack 41 is fixedly mounted on the housing 10. The drive gear 42 is rotatably arranged and is drivenly connected to the air distribution plate 20. The drive gear 42 meshes with the arc-shaped rack 41 and is movably arranged on the arc-shaped rack 41 along its extension direction to drive the air distribution plate 20 to rotate. The cooperation between the arc-shaped rack 41 and the drive gear 42 is a highly efficient and stable transmission method, enabling smooth rotation of the air distribution plate 20. In principle, the arc-shaped rack 41 provides the trajectory for the drive gear 42's movement. Through gear meshing, the rotational motion of the motor is converted into linear or rotational motion of the air distribution plate 20. In terms of effect, this transmission mechanism not only ensures precise control of the air distribution plate 20 but also reduces operating noise and extends its service life. In other embodiments, alternative solutions such as lead screws or cam mechanisms can be used to achieve motion control of the air distribution plate 20, but this may increase the size and complexity of the equipment.

[0098] In this embodiment, there are at least two arc-shaped racks 41 and at least two drive gears 42. The at least two arc-shaped racks 41 and at least two drive gears 42 are located on both sides of the first air outlet 11 and / or the second air outlet 12, respectively. The at least two drive gears 42 and at least two arc-shaped racks 41 are arranged in a one-to-one correspondence. Each drive gear 42 is movably mounted on the corresponding arc-shaped rack 41. And / or, one end of the arc-shaped rack 41 is connected to the inner wall of the housing 10, so that when the drive gear 42 drives the air distribution plate 20 to rotate to the second open position, the air distribution plate 20 moves to one end of the arc-shaped rack 41 and abuts against the inner wall of the housing 10. And / or, the end of the arc-shaped rack 41 is provided with a limiting protrusion, so that when the drive gear drives the air distribution plate to rotate to the first open position or the second open position, the air distribution plate moves to the position abutting against the limiting protrusion.

[0099] The arrangement of multiple arc-shaped racks 41 and drive gears 42 improves the stability and smoothness of the air distributor 20's movement, preventing vibration and displacement under high-speed airflow. In principle, by increasing the number of drive points, the load can be distributed, reducing the pressure on each drive gear 42 and thus improving the reliability of the entire drive system. In terms of effectiveness, this design ensures stable operation of the air distributor 20 under various airflow modes, enhancing the user experience. In other embodiments, a more complex multi-stage gear drive or belt drive system can be used to achieve finer control of the air distributor 20, but this may increase cost and maintenance complexity.

[0100] Specifically, the ducted air conditioner further includes an air guide structure 50, which comprises an air duct frame 51 and an air guide plate 52. The air duct frame 51 is connected to the housing 10 and forms a connecting opening 511 that communicates with the first air outlet 11. The air guide plate 52 is rotatably disposed at the connecting opening 511. The design of the air guide structure 50 enables flexible adjustment of the airflow direction to meet the air supply needs in different scenarios. In principle, the rotation of the air guide plate 52 changes the direction of the airflow. By driving the air guide plate 52 with a motor, precise airflow control can be achieved. In terms of effect, this design provides a wider air supply range, enhancing the applicability and comfort of the air conditioner. In other embodiments, more complex airflow adjustment functions can be achieved by setting multiple independently controlled air guide plates or using a retractable air duct design, but this may increase the size and weight of the equipment.

[0101] During operation, when the airflow direction needs adjustment, the motor in the drive structure 40 starts, driving the drive gear 42 to move along the arc-shaped rack 41, thereby pushing the air distributor 20 to rotate to the desired position. Simultaneously, the air guide plate 52 in the air guide structure 50 also rotates under its own motor control to adjust the airflow direction. During use, users can select different airflow modes via remote control or smart terminal, such as unidirectional airflow, bidirectional airflow, or airflow at a specific angle. The duct unit will automatically adjust the positions of the air distributor 20 and air guide plate 52 according to the user's instructions to achieve the selected airflow effect. This intelligent control method not only simplifies the operation process but also improves the flexibility and comfort of air conditioning use.

[0102] like Figure 1 As shown, the ducted air conditioner includes a first housing 13, an air distribution box (corresponding to a second housing 14), a lower air outlet component (corresponding to an air guiding structure), an upper air outlet (corresponding to a second air outlet), and an electrical box 80. Specifically, the ducted air conditioner in this embodiment also includes a first fixing member 63 and a second fixing member 64. The first fixing member 63 can be an upper fixing nut, and the second fixing member 64 can be a lower fixing nut.

[0103] like Figure 2 The diagram shows the internal structure of the air distribution box and air outlet components, including the air outlet components, air distribution box, insulation material, guide gear (corresponding to an arc-shaped rack), drive gear, drive motor 43, stud (corresponding to a lifting rod), air distribution guide plate (corresponding to an air distribution plate), decorative frame, buckle 531, lower fixing nut, upper fixing nut, spacer nut (corresponding to a drive component), first air guide motor 54, and second air guide motor 55; wherein the first air guide motor 54 and the second air guide motor 55 are independently controlled stepper motors, which can realize the two air guide plates of the lower air outlet component to rotate in different directions or in the same direction.

[0104] like Figure 3 The diagram shows a cross-sectional view of the internal structure, revealing the internal structure and assembly relationship of the decorative frame, clip 531, inner air duct structure, outer frame structure, and studs in the lower air guide plate. The decorative frame is fixed to the lower part of the inner air duct structure via clip 531 for external decoration. The inner air duct structure and the outer frame structure are nested together, and the inner air duct structure is fixed to the outer frame structure via a combination of four studs and nuts. The outer frame structure is fixed to the lower part of the air distribution box with screws.

[0105] Specifically, when the air is in the upper air outlet position, the air distribution guide plate is located below the air distribution box, the lower air outlet is blocked, the lower air outlet component is in a closed state, and the upper air outlet is in an open state. The air volume generated by the fan can be blown out through the upper air outlet. The upper air outlet can be equipped with an external air outlet component or a simple air outlet grille, depending on the customer's decoration plan.

[0106] When the air is vented downwards and bidirectional airflow is achieved, bidirectional airflow can be achieved through the downward air outlet. The dashed arrows indicate the direction of airflow, while the solid arrows indicate the rotation direction of each component. The guide gear is fixed to the side of the duct unit by screws and is stationary, while the drive gear cooperates with the guide gear and moves on it.

[0107] The motor of the air distributor rotates clockwise, driving the drive gear and the air distributor to rotate clockwise until it reaches the upper air outlet, thus blocking the upper air outlet. At the lower outlet, one air guide plate rotates counterclockwise, and the other air guide plate rotates clockwise, allowing air to exit in two different directions. Alternatively, one air guide plate and the other air guide plate can rotate in the same direction to achieve air exit in the same direction.

[0108] Specifically, to accommodate installation on ceilings of varying thicknesses, the air guide structure is an adjustable lifting structure. The external frame structure is fixed below the air distribution box, while the internal air duct structure can be adjusted and moved using a combination of studs and nuts to adapt to different ceiling thicknesses. During adjustment, first loosen the four lower fixing nuts and four upper fixing nuts. Then, adjust the installation distance of the spacer nuts according to the ceiling thickness. After adjusting the spacer nuts, tighten the four upper fixing nuts upwards to secure the four studs, and tighten the four lower fixing nuts downwards to secure the studs and the internal air duct structure.

[0109] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: Through the innovative gear mechanism and air distribution structure, as well as the control method of the air guide plate, the direction of air outlet in the duct unit can be changed. The gear mechanism of the air distribution plate is reasonably arranged to utilize the principle of force-saving lever, and the gear mechanism can transmit a larger torque, thereby enabling the adjustment of the angle of the air distribution plate while the fan is rotating, without being affected by the wind force of the fan rotation. This gear mechanism is simple and reliable. Through the stud combination mechanism and air outlet structure design, the air outlet component can be adjusted and fixed according to the thickness of the ceiling, and can be adapted to ceilings of any thickness on the market. The innovative use of the nested cooperation between the external frame structure and the internal air duct structure enables the air outlet component to be adjusted according to the thickness of the ceiling without air leakage.
