Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a ducted air conditioner and an air conditioner. Background Art

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

[0003] Ducted air conditioners typically have only a single air outlet on the front, with the airflow direction adjusted by the tilting angle of the air deflector. This structural design has obvious limitations. When the air deflector rotates too far, while the airflow range can be expanded, the effective airflow area of ​​the air outlet is significantly reduced, resulting in a significant reduction in airflow volume and a negative impact on the user experience. However, if the air deflector rotates too far, the airflow direction cannot be adjusted over a wide range. This contradiction makes it impossible for traditional ducted air conditioners to simultaneously meet the requirements of wide-area airflow adjustment and high airflow output.

[0004] In addition, the design of a single air outlet also limits the flexibility of airflow distribution, and it is impossible to supply air in multiple directions according to the needs of different usage scenarios. Especially in scenarios where the air supply needs of different areas need to be met at the same time, the duct air conditioner with a single air outlet cannot achieve flexible airflow distribution, resulting in uneven indoor temperature distribution, affecting the overall comfort. The movement trajectory and structural design of the air guide plate also directly affect the air outlet effect. In the existing technology, the movement mode of the air guide plate is often relatively simple, and the air supply direction can only be changed in a small range in the opening direction of a single air outlet, and the adjustment range of the air supply angle is relatively small. In view of the above problems, the existing technology is in urgent need of improvement. Summary of the Invention

[0005] The present application provides a duct air conditioner and an air conditioner to solve the problem that the duct air conditioner cannot take into account the requirements of wide-area air outlet regulation and high air volume output.

[0006] In a first aspect, some embodiments of the present application provide a duct air conditioner, comprising a shell and an air guide plate. An air outlet cavity is provided in the shell, and the air outlet cavity is provided with a first air outlet and a second air outlet, and the first air outlet and the second air outlet are located at two adjacent side walls of the shell. The air guide plate is located in the air outlet cavity and is connected to the shell, and the air guide plate is configured to rotate along a circular line in the air outlet cavity to switch between a first adjustment state, a second adjustment state and a third adjustment state. The air guide plate in the first adjustment state closes the first air outlet. The air guide plate in the second adjustment state closes the second air outlet. The air guide plate in the third adjustment state is at least partially located on the side of the first air outlet away from the second air outlet to open the first air outlet and the second air outlet.

[0007] In an optional embodiment, the wind deflector includes an inner wall, an outer wall and a wind deflecting surface.

[0008] When the air deflector is in the first adjustment state, the side of the air deflector facing the first air outlet is the outer wall, and the side of the air deflector facing away from the first air outlet is the inner wall. The inner wall has an inner curved surface structure, and the outer wall has an outer curved surface structure. Along the width of the air deflector, one edge of the inner wall intersects with one edge of the outer wall, and the other edge of the inner wall and the other edge of the outer wall intersect with the air deflector surface. When the air deflector is in the second adjustment state, the air deflector surface is located on the side of the air deflector closest to the first air outlet.

[0009] In an optional embodiment, the air guide surface is a planar structure. When the air guide plate is in the second adjustment state, the first angle between the air guide surface and the horizontal plane is 5-30°, and the side of the air guide surface facing the air outlet cavity is lower.

[0010] In an optional embodiment, when the air guide plate is in the third adjustment state, along the width direction of the air guide plate, a second angle formed by a tangent of the inner wall at the end away from the air guide surface and the horizontal direction is 30-60°.

[0011] In an optional embodiment, in a plane perpendicular to the length direction of the air deflector, the vertical projection of the outer side wall coincides with the maximum rotation trajectory of the air deflector.

[0012] In an optional embodiment, the ducted air conditioner further includes a heat exchanger and a water tray. The heat exchanger is disposed within the air outlet cavity, and the water tray is disposed within the air outlet cavity and below the heat exchanger. The water tray is bent toward the first air outlet and positioned proximate to the heat exchanger. When the air deflector is in the second adjustment state, the minimum spacing between the end of the air deflector distal to the first air outlet and the water tray is less than or equal to 5 mm.

[0013] In an optional embodiment, the first air outlet is located on the front side of the housing.

[0014] In an optional embodiment, the second air outlet is located on the lower side of the housing.

[0015] In an optional embodiment, the ratio of the opening area of ​​the second air outlet to the opening area of ​​the first air outlet is 0.5-0.7.

[0016] In an optional embodiment, the ducted air conditioner further includes a limit assembly and a drive assembly, wherein the limit assembly is connected to at least the air deflector. The drive assembly is located within the air outlet cavity and is connected to the housing and the limit assembly to drive the air deflector to switch and rotate between the first adjustment state, the second adjustment state, and the third adjustment state.

[0017] In one optional embodiment, the limiting assembly includes a guide groove and a guide rail member. The guide rail members are connected to both ends of the air deflector along the length of the air deflector. The housing is provided with guide grooves on opposite sides of the air outlet cavity, and one guide rail member is pluggably adapted to fit within each guide groove. The drive assembly includes a drive motor and a drive gear set. At least one guide rail member is provided with a plurality of transmission teeth along its length. The drive motor is meshed with the transmission teeth via the drive gear set to drive the air deflector to switch and rotate between a first adjustment state, a second adjustment state, and a third adjustment state.

[0018] In a second aspect, some embodiments of the present application provide an air conditioner, including the duct air conditioner in the above aspect.

[0019] The technical solutions provided by the embodiments of the present application may have the following beneficial effects:

[0020] In traditional solutions, the air guide plate can only swing within the range of a single air outlet. This solution achieves multi-dimensional adjustment of the air outlet direction by setting up dual air outlets and switching air guide modes. In traditional solutions, the swing angle of the air guide plate is inversely proportional to the air outlet area. This solution expands the air supply angle adjustment range while maintaining the effective air flow area through a switching mechanism for adjusting the air guide plate position. It can even exhaust air simultaneously through the first and second air outlets, covering a larger area for air supply and maintaining a larger air flow area at the air outlet, thereby achieving the purpose of simultaneous wide-area air outlet and high air volume output.

[0021] Through the above technical solution, this application effectively solves the contradiction between adjusting the air outlet angle and maintaining the air outlet volume. When a large range of air supply is required, the air guide plate can open the first air outlet and the second air outlet at the same time to ensure sufficient air flow through the area. When directional air supply is required, the first air outlet or the second air outlet is closed to achieve precise airflow guidance at the other air outlet. This dynamic adjustment method not only retains the air supply direction control capability of the traditional structure, but also increases the maximum air supply volume through the coordinated work of the two air outlets, meeting the differentiated needs in different usage scenarios.

[0041] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0042] The following provides many different embodiments or examples for implementing different structures of the present application. To simplify the present application, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0043] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

Figure 7 for Figure 1 A schematic diagram of a partial structure of the connection between the air guide plate and the guide rail member is shown in FIG.

[0045] In the operational architecture of ducted air conditioners, the single-sided outlet design of the air outlet cavity creates a structural contradiction between the air deflector's trajectory and air output efficiency. When the air deflector rotates at a large angle to expand the air outlet coverage, its physical displacement directly compresses the outlet's effective flow area, resulting in a negative correlation between the airflow channel cross-sectional area and the deflector's rotation angle. This negative correlation makes it impossible for the system to simultaneously meet the design requirements of wide-area air delivery and high air volume output.

[0046] For example, in the central air-conditioning system of a commercial venue, due to the high floor height of the indoor space, the terminal duct unit needs to deliver air to the lower area in the vertical direction and the front area in the horizontal direction at the same time. The traditional single air outlet structure forces the air guide plate to almost or completely close the front channel in the downward air supply mode, resulting in interruption of the horizontal airflow. In the mixed air supply mode, the turbulent boundary layer formed by the air guide plate partially blocking the air outlet will cause a surge in local pressure loss. Experimental data shows that when the downward rotation angle of the air guide plate exceeds 45°, the air volume attenuation rate can reach 38%, and the air flow uniformity index drops below 0.7. Under this operating condition, the equipment needs to continuously increase the fan speed to compensate for the air volume loss, which directly leads to an increase in the energy consumption coefficient and greater fan and aerodynamic noise.

[0047] In the above example, the system will remain in a suboptimal operating range for a long time, resulting in a continuous decline in heat exchange efficiency. The temperature gradient caused by uneven airflow distribution will exacerbate the laminar separation of indoor air, forcing the compressor to frequently start and stop to maintain the set temperature, thereby shortening the mechanical life of key components. More seriously, in high temperature and high humidity environments, the accumulation of condensation in localized areas due to insufficient airflow coverage will significantly increase the probability of mold growth, threatening the air quality safety level.

[0048] Based on this, see Figures 1 to 7 The embodiments of the present application provide a duct air conditioner and an air conditioner to solve the problem that the duct air conditioner cannot take into account the requirements of wide-area air outlet regulation and high air volume output.

[0049] On the one hand, if Figure 1As shown, an embodiment of the present application provides an air duct machine 100, which includes a shell 10 and an air guide plate 20. An air outlet cavity 11 is provided in the shell 10, and the air outlet cavity 11 is provided with a first air outlet 13 and a second air outlet 14. The first air outlet 13 and the second air outlet 14 are located at two adjacent side walls of the shell 10. The air guide plate 20 is located in the air outlet cavity 11 and is connected to the shell 10. The air guide plate 20 is configured to rotate along a circular line in the air outlet cavity 11 to switch between a first adjustment state, a second adjustment state and a third adjustment state. The air guide plate 20 in the first adjustment state closes the first air outlet 13. The air guide plate 20 in the second adjustment state closes the second air outlet 14. The air guide plate 20 in the third adjustment state is located on the side of the first air outlet 13 away from the second air outlet 14 to open the first air outlet 13 and the second air outlet 14.

[0050] The air outlet cavity 11 refers to the airflow channel space formed within the housing 10. Specifically, it can be formed by enclosing internal partitions of the housing 10 and is used to guide the airflow in a certain direction. The first air outlet 13 and the second air outlet 14 on two adjacent side walls refer to ventilation openings opened on two mutually perpendicular or angled walls of the housing, such as the combination of the front side wall and the lower side wall. The first air outlet 13 can be the front air outlet, and the second air outlet 14 can be the lower air outlet, so that multi-directional air supply can be achieved through the first air outlet 13 and the second air outlet 14.

[0051] Circular rotation refers to the arc-shaped motion of the air guide plate 20 around a fixed axis. This can be achieved through a rotating shaft connection structure or a guide rail limit structure to ensure the stability of the motion trajectory of the air guide plate 20. The closed state occurs when the air guide plate 20 completely blocks the corresponding air outlet, such as when both ends of the air guide plate 20 along the width direction contact or fit with the corresponding edges of the air outlet to achieve a blocking seal, effectively blocking airflow through the air outlet. The open state occurs when the air guide plate 20 is partially or completely removed from the air outlet area, allowing air to flow smoothly through the air outlet.

[0052] For example, the first air outlet 13 is a front air outlet, and the second air outlet 14 is a bottom air outlet. The first air outlet 13 and the second air outlet 14 are openings respectively provided on two adjacent side walls of the housing 10. Specifically, they can be implemented by combining the front side wall and the bottom side wall. The two air outlets can form complementary air supply paths through a spatially staggered design.

[0053] The first, second, and third adjustment states refer to the three positions of the air guide plate 20 during its rotation. These can be achieved by configuring mechanical limiters corresponding to different rotation angles. These three states correspond to air supply modes in which the first air outlet 13 is closed, the second air outlet 14 is closed, and both air outlets are open.

[0054] When concentrated air supply to the front is required, Figure 2 As shown, the air guide plate 20 rotates to above the second air outlet 14 to completely block the second air outlet 14, so that the air in the air outlet cavity 11 is only discharged forward from the first air outlet 13. At this time, the air guide plate 20 is in the second adjustment state.

[0055] When it is necessary to supply air to the downward side, such as Figure 3 As shown, the air guide plate 20 moves to the rear of the first air outlet 13 to completely close the first air outlet 13, so that the air in the air outlet cavity 11 is only discharged downward from the second air outlet 14. At this time, the air guide plate 20 is in the first adjustment state.

[0056] When you need to open two air outlets at the same time, Figure 4 As shown, at least the main portion of the air deflector 20 rotates to the side of the first air outlet 13 away from the second air outlet 14, so that both the first air outlet 13 and the second air outlet 14 are in an open state. At this time, the air in the air outlet cavity 11 can be discharged forward through the first air outlet 13 or downward through the second air outlet 14. At this time, the air deflector 20 is in the third adjustment state.

[0057] The circular motion trajectory of the air guide plate 20 enables it to smoothly transition between different working positions, namely the first adjustment state, the second adjustment state and the third adjustment state, thereby avoiding the mechanism interference problem caused by traditional linear motion.

[0058] In the traditional solution, the air guide plate 20 can only swing within the range of a single air outlet. This solution achieves multi-dimensional adjustment of the air outlet direction by setting up dual air outlets and switching air guide modes. In the traditional solution, the swing angle of the air guide plate 20 is inversely proportional to the air outlet area. This solution expands the air supply angle adjustment range while maintaining the effective air flow area by switching the position adjustment mechanism of the air guide plate 20. It can even exhaust air simultaneously through the first air outlet 13 and the second air outlet 14, which can cover a larger area for air supply and maintain a larger air flow area at the air outlet, thereby achieving the purpose of simultaneous wide-area air discharge and high air volume output.

[0059] Through the above technical solution, the present application effectively solves the contradiction between adjusting the air outlet angle and maintaining the air outlet volume. When a large range of air supply is required, the air guide plate 20 can open the first air outlet 13 and the second air outlet 14 at the same time to ensure sufficient air flow through the area. When directional air supply is required, the first air outlet 13 or the second air outlet 14 is closed to achieve precise airflow guidance at the other air outlet. This dynamic adjustment method not only retains the air supply direction control capability of the traditional structure, but also increases the maximum air supply volume through the coordinated work of the two air outlets, meeting the differentiated needs in different usage scenarios.

[0060] For example, the housing 10 of the ducted air conditioner 100 is a rectangular parallelepiped structure, with an air outlet cavity 11 disposed within the housing. A first air outlet 13 is located on the front side of the housing 10, and a second air outlet 14 is located at the bottom of the housing 10. The air deflector 20 is a curved plate-like structure, with its ends connected to the inner wall of the housing 10 via bearings or other limited transmission structures, allowing the air deflector 20 to rotate about its axis. The length of the air deflector 20 is comparable to the width of the air outlet cavity 11, and the length and width of the air deflector 20 are slightly larger than the air outlet dimensions.

[0061] The air deflector 20 is controlled by a drive motor to rotate. When the air deflector 20 rotates to the lower horizontal position, the second air outlet 14 is completely closed, and this is the second adjustment state. When the air deflector 20 rotates to the front vertical position, the first air outlet 13 is completely closed, and this is the first adjustment state. When the air deflector 20 rotates to the upper approximately horizontal position, both the first air outlet 13 and the second air outlet 14 are simultaneously opened, and this is the third adjustment state.

[0062] In actual use, the air deflector 20 can be controlled to rotate to different angles as needed. For example, in summer cooling mode, the air deflector 20 can be adjusted to the second adjustment position, with cool air blowing out of the bottom air outlet (i.e., the second air outlet 14). In winter heating mode, the air deflector 20 can be adjusted to the first adjustment position, with hot air blowing out of the front air outlet (i.e., the first air outlet 13). To quickly adjust the room temperature, the air deflector 20 can be adjusted to the third position, with both the first and second air outlets 13, 14 open.

[0063] Through the above scheme, the present application realizes flexible multi-directional air supply. By arranging the first air outlet 13 and the second air outlet 14 on the adjacent two sides of the shell 10, and adopting the air guide plate 20 that can rotate along the circumference, the limitations of the traditional single air outlet are broken through. The air guide plate 20 can flexibly switch between different adjustment states to achieve independent or simultaneous control of the two first air outlets 13 and the second air outlet 14, meeting the air supply needs in different scenarios. This design not only ensures a large air volume output, but also realizes a large-angle air outlet adjustment, thereby improving the applicability and user experience of the duct air conditioner 100. At the same time, the design of multiple air outlets increases the flexibility of air flow distribution, and can perform multi-directional air supply according to different usage scenarios, thereby improving the uniformity of indoor temperature and improving the efficiency of air conditioning.

[0064] Among them, Figure 5 As shown, the wind deflector 20 includes an inner wall 21, an outer wall 22 and a wind guide surface 23. The inner wall 21 is an inner arc surface structure, and the outer wall 22 is an outer arc surface structure. Figure 3 In the first adjustment state shown, the side of the air guide plate 20 facing the first air outlet 13 is the outer wall 22 , and the side of the air guide plate 20 facing away from the first air outlet 13 is the inner wall 21 .

[0065] Along the width of the air deflector 20, one side edge of the inner wall 21 and one side edge of the outer wall 22 intersect with the air deflector surface 23, and a small gap exists between the other side edge of the inner wall 21 and the other side edge of the outer wall 22. For example, the other side edge of the inner wall 21 and the other side edge of the outer wall 22 intersect or form a connecting surface that is smaller than the width (or thickness). This ensures that the end of the air deflector 20 closer to the air deflector surface 23 along the width direction has a larger thickness, while the end farther from the air deflector surface 23 has a smaller thickness.

[0066] When the air guide plate 20 is in Figure 2 and Figure 5 In the second adjustment state shown, the air guide surface 23 is located on a side of the air guide plate 20 close to the first air outlet 13 .

[0067] The inner wall 21 is an inner curved surface structure that points the air guide plate 20 toward the interior of the air outlet cavity 11 when closed. It is used to guide airflow along the surface of the inner wall 21, with minimal flow resistance and noise. The outer wall 22 is an outer curved surface structure that points the air guide plate 20 toward the exterior of the air outlet when closed. It is used to conform to the edge of the air outlet when switching between adjustment states, allowing for smooth rotation and achieving a good sealing effect. The air guide surface 23 is a transition plane connecting the inner wall 21 and the outer wall 22, and is used to adjust the air outlet angle at the first air outlet 13 in the second adjustment state.

[0068] Specifically, if Figure 3 and Figure 5 As shown, when the air deflector 20 is rotated to the first adjustment state, the outer wall 22 contacts or fits at least the upper and lower edges of the first air outlet 13, thereby closing the first air outlet 13. The inner wall 21 forms a channel to guide the airflow, so that the airflow flowing to the first air outlet 13 is guided by the inner curved surface and diverted to the second air outlet 14 for downward discharge.

[0069] like Figure 2 and Figure 5 As shown, in the second adjustment state, the outer wall 22 can contact or fit the front and rear edges of the second air outlet 14 to close the second air outlet 14. The inner wall 21 forms a channel to guide the airflow, so that the airflow at the bottom of the air outlet cavity 11 can be guided along the inner curved surface and discharged forward to the first air outlet 13. During this process, the air guide surface 23 can be set at the bottom of the first air outlet 13 to guide the airflow at the bottom of the first air outlet 13.

[0070] Traditional air deflectors use a single plane or simple curved surface, which can easily cause airflow leakage and turbulence when closed. This solution, however, combines the dual curved surfaces of the inner and outer walls 21 and 22 with the air guide surface 23 to form a composite curved surface. This continuous design of the outer curved surface significantly improves the compatibility of the rotation trajectory with the housing structure, achieving at least a double seal through the outer wall 22 when closed.

[0071] Furthermore, the curved surface design of the inner wall of the air guide plate 20 effectively reduces the wind resistance during the passage of airflow, avoids noise caused by structural mutations, and improves air outlet efficiency and user experience.

[0072] In some embodiments, as Figure 2 and Figure 5 As shown, the wind guide surface 23 is a planar structure. When the wind guide plate 20 is in the second adjustment state, the first angle α between the wind guide surface 23 and the horizontal plane is 5-30°, and the side of the wind guide surface 23 facing the air outlet cavity 11 is lower.

[0073] The planar structure of the air guide surface 23 can reduce turbulence during airflow and improve air supply efficiency. By adjusting the first angle of the air guide surface in the second adjustment state, the air supply angle through the first air outlet 13 can be controlled (the first angle can be regarded as the air supply angle in the second adjustment state).

[0074] That is, when the air guide plate 20 is switched to the second adjustment state, the first angle α between the air guide surface 23 and the horizontal plane is controlled within a range of 5-30°. This first angle α can be 5°, 10°, 15°, 20°, 25°, or 30°. Furthermore, the side of the air guide surface 23 closest to the air outlet cavity 11 is positioned lower, allowing air to flow diagonally upward through the first air outlet 13, avoiding direct airflow onto the user, resulting in a better user experience.

[0075] Among them, when the first angle α is less than 5°, it is necessary to make the air guide plate 20 in the second adjustment state continue to rotate toward the inside of the air outlet cavity 11, which will seriously squeeze the layout space of other components in the air outlet cavity 11. In addition, under refrigeration conditions, a smaller air supply angle causes the cold air to settle downward faster, making the effective air supply distance of the cold air shorter. If the first angle α is greater than 30°, the air flow discharged from the first air outlet 13 has a larger deflection angle obliquely upward, which is not conducive to maintaining a larger air supply distance. Based on this, by setting the range of the first angle α to 5-30°, it is possible to maintain a larger air supply distance without excessively occupying the layout space of other components in the air outlet cavity 11.

[0076] In addition, if Figure 3 and Figure 5As shown, when the air guide plate 20 is in the third adjustment state, along the width direction of the air guide plate 20, the inner wall 21 is arranged obliquely downward at the end away from the air guide surface 23, and the second angle β formed by the tangent of the end and the horizontal direction is 3060°.

[0077] The second angle β refers to the inclination angle between the tangent line at the end of the inner sidewall 21 and the horizontal plane. This can be achieved by adjusting the curvature of the inner arc surface or the position of the air guide plate 20 in the third adjustment state. In the upper portion of the air outlet cavity 11, some air is guided and diverted by the inner sidewall 21, leaving the inner sidewall 21 at the aforementioned end and being discharged through the first air outlet 13. By adjusting the second angle β, the air delivery angle of the first air outlet 13 in the third adjustment state can be adjusted to meet the varying needs of users while providing a wide range of air delivery.

[0078] Exemplarily, the second angle β can be set to 30°, 35°, 40°, 45°, 50°, 55° or 60°. Among them, when the second angle β is less than 30°, it is necessary to make the air guide plate 20 in the third adjustment state continue to rotate toward the second air outlet 14, thereby increasing the blocking area of ​​the first air outlet 13, so that the overall air outlet area is quickly reduced. If the second angle β is greater than 60°, the airflow discharged from the first air outlet 13 has a larger deflection angle from bottom to front, and the air outlet resistance at the first air outlet 13 is smaller, so that more airflow in the air outlet cavity 11 is discharged forward from the first air outlet 13, that is, the airflow discharged downward from the second air outlet 14 is less, so that the uniformity of the air volume discharged from the first air outlet 13 and the second air outlet 14 is lower. Based on this, by setting the second angle β to a range of 30-60°, the first air outlet 13 and the second air outlet 14 can maintain a larger air outlet volume as a whole, and the amount of air discharged from the first air outlet 13 and the second air outlet 14 can be more evenly distributed, providing a better user experience.

[0079] Among them, Figure 1 As shown, in a plane perpendicular to the length direction of the air deflector 20 , the vertical projection of the outer side wall 22 coincides with the maximum rotation trajectory of the air deflector 20 .

[0080] Among them, the outer wall 22 refers to the side surface of the air guide plate 20 facing the air outlet when the first air outlet 13 is closed. The rotation trajectory is the circular motion path formed when the air guide plate 20 rotates around the axis, and the maximum rotation trajectory refers to the circular motion path with the largest radial dimension. That is to say, in the plane perpendicular to the length direction of the air guide plate 20, the outer wall 22 of the air guide plate 20 is designed to be an arc structure, and its curvature radius is equal to the radius of the maximum rotation track of the air guide plate 20. During the rotation of the air guide plate 20, the vertical projection of the outer wall 22 always remains consistent with its maximum rotation trajectory. For example, when the maximum rotation angle of the air guide plate 20 is 90 degrees, the arc length of the outer wall 22 is exactly equal to one-quarter of the circumference. This design allows the air guide plate to maximize the use of the air outlet space at any rotation position, avoiding airflow leakage caused by excessive gap between the air guide plate and the shell.

[0081] Thus, in a plane perpendicular to the length of the air deflector 20, by arranging the inner walls of the upper and lower edges of the first air outlet 13 and the inner walls of the front and rear edges of the second air outlet to form a cocircular structure, the air deflector 20 maintains good contact and fit with the inner walls of the upper and lower edges of the first air outlet 13 and the inner walls of the front and rear edges of the second air outlet 14 during the rotational switching process between the first, second, and third adjustment states, thereby forming a good contact seal and providing a good sealing effect for the first air outlet 13 or the second air outlet 14, thereby preventing air leakage that could affect the air supply effect and air discharge efficiency of the other air outlets.

[0082] This solution achieves a geometric match between the motion path of the air guide plate 20 and the cavity structure by constraining the projection of the outer wall 22 and the rotation trajectory, thereby significantly reducing or eliminating the ineffective gap between the air guide plate 20 and the housing 10, achieving a close fit between the air guide plate and the housing, effectively reducing air leakage, and improving air outlet efficiency. At the same time, the air guide plate can maintain an optimal spacing from the housing at different rotation angles, ensuring that the effective area of ​​the air outlet will not be significantly reduced due to the rotation of the air guide plate. This design not only optimizes the air outlet performance of the ducted air conditioner, but also improves the flexibility and accuracy of the air guide plate adjustment, allowing the ducted air conditioner to better adapt to different usage scenarios and air outlet requirements.

[0083] In addition, the above structure is also helpful in solving the problem of poor movement caused by structural interference during the rotation of the air guide plate 20, ensuring that the air guide plate 20 can maintain stable operation under different adjustment states, while reducing the air volume loss caused by uneven gaps and improving the air outlet efficiency.

[0084] For the duct machine 100, Figure 1As shown, the ducted air conditioner 100 further includes a fan 30. For example, in the case where both the air inlet cavity 12 and the air outlet cavity 11 are provided within the housing 10, the air inlet cavity 12 is provided with an air inlet 15. The fan 30 is located within the air inlet cavity 12. The rotation of the fan 30 drives air from the air inlet 15 through the air inlet cavity 12 and the air outlet cavity 11, and is then blown out through at least one of the first air outlet 13 and the second air outlet 14.

[0085] Alternatively, the housing 10 may also include only the air outlet cavity 11. In this case, the air outlet cavity 11 is correspondingly provided with an air inlet, and the fan 30 is installed at the air inlet to drive air from the air inlet into the air outlet cavity 11 and blown out from at least one of the first air outlet 13 and the second air outlet 14.

[0086] Continue to refer to Figure 1 The duct air conditioner 100 further includes a heat exchanger 40. The heat exchanger 40 is a component used to adjust the temperature or humidity of the air. For example, if the heat exchanger 40 is a fin-type structure, the heat exchanger 40 disposed in the air outlet cavity 11 can cool or heat the air flowing through the heat exchanger 40 to adjust the temperature and humidity of the air.

[0087] That is to say, the air flow can be driven by the fan 30. For example, the fan 30 can use a centrifugal fan or an axial flow fan. Through the rotation of the fan 30, the air is driven to flow from the air inlet 15 through the air inlet cavity 12 and the air outlet cavity 11 in sequence. The air can be heated or cooled by flowing through the heat exchanger 40 in the air outlet cavity 11, and then the air can be blown out through at least one of the first air outlet 13 and the second air outlet 14 to adjust the temperature and humidity.

[0088] like Figure 1 As shown, the air duct unit 100 further includes a water receiving tray 50, which is disposed below the heat exchanger 40. The water receiving tray 50 is bent toward one end of the first air outlet 13 and is disposed close to the heat exchanger 40. Figure 2 When the air guide plate 20 is in the second adjustment state, the minimum distance between the end of the air guide plate 20 away from the first air outlet 13 in the width direction and the water receiving tray 50 is less than or equal to 5 mm.

[0089] The water pan 50 is a container that collects condensed water from the surface of the heat exchanger 40. It can be made of metal or plastic. Its curved front end (i.e., the end closest to the first air outlet 13) allows it to conform to the contours of the heat exchanger's bottom, improving water collection efficiency. The water pan 50 is shallow, with a bottom that is slightly tilted toward the center to facilitate drainage of accumulated water. The minimum spacing refers to the shortest vertical distance between the end of the guide plate 20 and the bottom of the water pan 50 in the second adjustment state.

[0090] In the process of collecting condensed water dripping from the heat exchanger 40 , the structure of the water receiving tray 50 with its front end bent upward can prevent the water droplets from splashing forward and polluting the indoor environment.

[0091] In this way, when the air guide plate 20 is in the second adjustment state of closing the second air outlet 14, the gap between the end of the air guide plate 20 and the water receiving tray 50 is limited to within 5 mm, which can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm or direct contact between the two. On this basis, by setting the front end of the water receiving tray 50 to be bent upward, the air guide plate 20 in the second adjustment state can rotate deeper into the air outlet cavity 11. In this way, the air guide plate 20 has a smaller overlapping width with the first air outlet 13 at one end of the air guide surface 23, so that the first air outlet 13 has a larger air outlet area in the second adjustment state. At the same time, it is beneficial to make the first angle have a smaller setting adjustment range.

[0092] In other words, the curved design at the front end of the water tray 50 cooperates with the air guide plate 20 to form a nearly closed air flow channel in the second adjustment state, effectively directing airflow out of the first air outlet 13. Furthermore, the slight gap between the air guide plate 20 and the water tray 50 does not affect the flexible rotation of the air guide plate 20, while minimizing air leakage and preventing the air guide plate 20 from excessively blocking the first air outlet 13 in the second adjustment state, thereby improving air outlet efficiency. Furthermore, this structural design facilitates cleaning and maintenance, effectively preventing dust from accumulating in the gap between the water tray 50 and the air guide plate 20.

[0093] Exemplarily, the first air outlet 13 is located on the front side of the housing 10, i.e., the first air outlet 13 is the front air outlet of the housing 10 and is used to convey airflow forward. When the heat exchanger 40 in the air outlet cavity 11 is operating as an evaporator, the cold air discharged from the first air outlet 13 can cover the upper space of the room and gradually settle downward, thereby preventing excessive cold air from accumulating in the lower area of ​​the room, which is beneficial for improving the uniformity of cold air distribution in the room.

[0094] Correspondingly, the second air outlet 14 is located on the lower side of the housing 10, i.e., the second air outlet 14 is the lower side air outlet of the housing 10, and is used to output airflow downward. When the heat exchanger 40 in the air outlet cavity 11 is operating as a condenser, the hot air discharged from the second air outlet 14 can be blown downward to the lower area of ​​the room. Due to the rising nature of hot air, the hot air at the bottom rises to form air convection, thereby preventing excessive hot air from accumulating in the upper area of ​​the room, which helps to improve the uniformity of hot air distribution indoors.

[0095] The ratio of the opening area of ​​the second air outlet 14 to the opening area of ​​the first air outlet 13 is 0.5-0.7, which means that the ventilation cross-sectional areas of the two are maintained within a specific ratio range. Specifically, this ratio range can be achieved by adjusting the length or width of the air outlet. This ratio range can balance the flow distribution of the two air outlets. Since the length dimensions (i.e., length dimensions) of the first air outlet 13 and the second air outlet 14 are approximately equal, the opening area ratio can be regarded as the ratio of the width dimension (i.e., the opening dimension in the front-to-back direction) of the second air outlet 14 to the width dimension (i.e., the opening dimension in the up-down direction) of the first air outlet 13 meeting 0.5-0.7, which can be 0.5, 0.55, 0.6, 0.65 or 0.7, without limitation.

[0096] Among them, when the air guide plate 20 is switched to the third adjustment state, the two air outlets are opened at the same time. Since the air outlet area of ​​the first air outlet 13 on the front side is larger, the air supply in the horizontal direction can be guaranteed first. The air outlet area of ​​the second air outlet 14 on the lower side is smaller, thereby supplementing the air supply demand in the vertical direction. The setting of the opening area ratio of 0.5-0.7 makes the air flow distribution of the two air outlets form a primary and secondary relationship, avoiding mutual interference of airflow. For example, if the area of ​​the front air outlet is 0.1 square meters, the area of ​​the lower air outlet is controlled within the range of 0.05-0.07 square meters, which not only maintains the main air outlet efficiency of the front side, but also ensures that the air outlet volume on the lower side meets the needs of the local area. This ratio range has been verified by experiments, which can balance the relationship between the air outlet pressure loss and the air volume distribution in the two directions, and prevent air flow turbulence or increased noise due to excessive area differences.

[0097] When the air guide plate 20 is in the first adjustment state, the open second air outlet 14 has a smaller air outlet area, resulting in a higher air velocity and a greater air delivery distance. For example, when the ducted air conditioner 100 is in heating mode, the higher-velocity hot air can be delivered downwards a greater distance (i.e., reach a lower altitude), thereby fully heating the air at the bottom of the room and achieving a more uniform temperature distribution throughout the room.

[0098] There are various implementations for the rotational switching of the air guide plate 20 between the first adjustment state, the second adjustment state and the third adjustment state.

[0099] like Figure 6 and Figure 7 As shown, the duct air conditioner 100 further includes a limit assembly 60 and a drive assembly 70. The limit assembly 60 is connected to at least the air guide plate 20. The drive assembly 70 is located within the air outlet cavity 11 and is connected to the housing 10 and the limit assembly 60 to drive the air guide plate 20 to switch and rotate between the first adjustment state, the second adjustment state, and the third adjustment state.

[0100] Among them, the limiting component 60 refers to a structural component used to limit the movement trajectory of the air guide plate 20, and has a variety of settings. For example, the limiting component 60 includes at least two other bracket plates or at least two bracket frames. At least two bracket plates (or bracket frames) are spaced apart along the length direction of the air guide plate 20 and connected to one side of the inner wall 21. For example, the two ends of the air guide plate 20 along the length direction are respectively connected to the first end of a bracket plate, and the second end of the bracket plate is located in the air outlet cavity 11 and is rotatably connected to the shell 10, so that the connection line between the second ends of the two bracket plates is the rotation axis of the air guide plate 20. At this time, by connecting the driving component 70 (such as a rotary motor, a stepping motor, a servo motor or a reduction motor) at the second end of the bracket plate, the air guide plate 20 is driven to rotate and switch between the first adjustment state, the second adjustment state and the third adjustment state through the second end of the bracket plate.

[0101] Or, as Figure 6 and Figure 7 As shown, the limiting assembly 60 includes a guide groove 61 and a guide rail member 62. Along the length direction of the air guide plate 20, both ends of the air guide plate 20 are connected to the guide rail member 62. For example, the air guide plate 20 and the guide rail member 62 are detachably connected or the two are an integral component. The shell 10 is provided with a guide groove 61 on opposite sides of the air outlet cavity 11. A guide rail member 62 is plugged and adapted with a guide groove 61, so that the air guide plate 20 can be rotated and switched between the first adjustment state, the second adjustment state and the third adjustment state under the limiting action of the guide groove 61 and the guide rail member 62. That is, the extension direction of the guide groove 61 and the guide rail member 62 coincides with the rotation trajectory of the air guide plate 20 (or is a concentric circle). Correspondingly, the drive assembly 70 includes a drive motor 71 and a drive gear set 72. At least one guide rail member 62 is provided with a plurality of transmission teeth along its length direction. The drive motor 71 is engaged with the transmission teeth through the drive gear set 72 to drive the air guide plate 20 and the guide rail member 62 to rotate along the length direction of the guide groove 61, so that the air guide plate 20 switches and rotates between the first adjustment state, the second adjustment state and the third adjustment state.

[0102] The guide groove 61 refers to a groove structure provided on both sides of the air outlet cavity 11 of the housing 10, specifically implemented as a U-shaped or T-shaped cross-section groove, which is used to limit the movement path of the guide member 62. The guide member 62 refers to a sliding component connected to both ends of the air deflector 20, specifically made of metal or engineering plastic. Its plug-in end forms a sliding pair with the guide groove 61, allowing the air deflector 20 to rotate along the circumferential path of the guide groove 61. The transmission teeth refer to a tooth structure distributed continuously along the length of the guide member 62, specifically in the form of straight teeth or helical teeth, which mesh with the gears of the drive gear set 72 to transmit power.

[0103] The driving gear set 72 refers to a reduction gear system connected by the output shaft of the driving motor 71. While realizing the reduction transmission of the driving motor 71 through the driving gear set 72, the multiple passive gears in the driving gear set 72 are also engaged with the guide rail member 62, that is, the guide rail member 62 has at least two spaced-apart engagement points with the driving gear set 72 along the length direction, which is beneficial to improving the circumferential rotation stroke of the guide rail member 62 and the air guide plate 20 driven by the driving motor 71, so that the air guide plate 20 can be rotated and switched in a wide range between the third adjustment state and the second adjustment state to adapt to a larger width of the air outlet.

[0104] Among them, the pitch of the transmission teeth matches the tooth profile of the driving gear set to ensure the continuity and accuracy of power transmission. The contour of the guide groove 61 is consistent with the rotation trajectory of the air deflector 20. Alternatively, the contour trajectory of the guide groove 61 is a concentric circle with a smaller radius corresponding to the rotation trajectory of the air deflector 20. At this time, the guide rail member 62 is radially connected to the inner side of the air deflector 20, so that the air deflector 20 can slide on a larger circumferential trajectory under the limitation of the inner guide groove 61 and the guide rail member 62. The moving stroke (i.e., the rotation angle) of the guide rail member in the guide groove corresponds to the range of the rotation angle of the air deflector. When the drive motor stops, the friction between the guide rail member 62 and the guide groove 61 and the meshing force between the transmission teeth and the gear set form a self-locking function, maintaining the air deflector 20 in a fixed position in the target adjustment state.

[0105] The present invention effectively constrains the motion trajectory of the air deflector 20 during rotation by interlocking the guide rail member 62 with the guide slot 61, preventing the air deflector 20 from deflecting or getting stuck. The meshing transmission of the drive gear set 72 and the transmission teeth of the guide rail member 62 ensures repeatable and precise switching of the air deflector 20's state, ensuring stable switching between the opening and closing states of the air outlet, thereby resolving the problem of fluctuating airflow caused by uncontrolled motion trajectory of the conventional air deflector 20.

[0106] It should be noted that, along the length direction of the air guide plate 20, since the air outlet cavity 11 is provided with plug-in adaptable guide grooves 61 and guide rail parts 62 on two oppositely arranged inner walls, the air guide plate 20, the upper and lower edges of the first air outlet 13 and the front and rear edges of the second air outlet 14 are cooperated, so that the air guide plate 20 cooperates with the limiting component 60 in the four directions of up and down (or front and back) and left and right with the inner wall of the shell 10 to have a better contact and sealing effect, so that the air guide plate 20 can have a more tight sealing effect on the first air outlet 13 and the second air outlet 14 in the first adjustment state and the second adjustment state, thereby avoiding the lower air outlet efficiency at the other air outlet due to pressure relief.

[0107] Illustratively, the rotational power output by the drive motor 71 is transmitted to the drive teeth of the guide rail member 62 via the drive gear set 72, causing the guide rail member 62 to move along the arcuate trajectory of the guide slot 61. The movement of the guide rail member 62 drives the air deflector 20 to rotate about a circular line. The meshing contact area between the drive teeth and the drive gear set 72 covers at least three tooth surfaces. When the air deflector 20 rotates to the target adjustment state, the guide rail member 62 forms a mechanical stop with the end of the guide slot 61. The meshing pressure of the drive gear set 72 and the drive teeth maintains the air deflector 20 in a stationary state.

[0108] For example, the start and stop signals of the drive motor 71 can be feedback-controlled via a position sensor on the rotation trajectory of the air deflector 20. Alternatively, the rotation angle of the air deflector 20 can be accurately controlled by a stepper motor or servo motor. Under preset parameters, without the need for sensor detection, the position angle of the air deflector 20 can be flexibly and accurately maintained by the rotation angle of the drive motor 71, ensuring that the repeatability of the state switching is controlled within a range of ±0.5°.

[0109] The above solution effectively solves the problem of the traditional ducted air conditioner 100's air deflector 20 easily deviating during rotation, leading to seal failure. The interlocking fit of the guide rail 62 and the guide slot 61 constrains the air deflector 20's freedom of movement, while the meshing transmission of the drive gear set 72 and the transmission gears ensures smooth power output. This structure ensures that the air deflector 20 maintains a precise circular motion trajectory when switching between different adjustment states, preventing loose outlet seals or misaligned guide surface angles caused by motion deviation, thereby ensuring precise control of air volume distribution and outlet direction.

[0110] In another aspect, an embodiment of the present application further provides an air conditioner comprising the ducted air conditioner 100 of the above aspect. Because the air conditioner comprises the ducted air conditioner 100 of the above aspect, the air conditioner has all the benefits of the ducted air conditioner 100, thereby resolving the issue that ducted air conditioners cannot achieve both wide-area air flow regulation and high air volume output. This will not be further described here.

[0111] For example, the duct unit 100 can be used as the indoor unit of the air conditioner, in conjunction with the outdoor unit (including at least a compressor and an outdoor heat exchanger) and a throttling device to form a refrigerant circulation path between the compressor, the outdoor heat exchanger, the throttling device, the heat exchanger 40 and the compressor, so as to efficiently heat or cool the air flowing through the heat exchanger 40 through the phase change heat transfer process of the refrigerant.

[0112] On this basis, the duct unit 100 as an indoor unit solves the technical contradiction of the traditional air conditioner's indoor unit having a single air outlet, which leads to a limited air supply direction and air volume loss. By setting a first air outlet 13 and a second air outlet 14 on adjacent side walls, and coordinating the switching of the air guide plate 20 between three working states, a multi-mode switching of front-side directional air supply, lower-side vertical air supply, and coordinated air supply from the front and lower double air outlets is achieved. In the dual-outlet open state, the geometric features of the inner arc surface of the air guide plate form a diversion guide surface, so that the airflow forms a complementary flow between the front and lower air outlets, which greatly (i.e., doubles) increases the total flow area and expands the airflow coverage range. This structure enables the air conditioner to flexibly adjust the air supply direction according to environmental requirements, avoids local airflow blockage caused by adjusting the angle of the air guide plate, and maintains the stability of the air volume output.
