Description

Technical Field

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

[0002] Traditional household wall-mounted air conditioners consist of an indoor unit and an outdoor unit. However, regardless of the model, the indoor unit contains core components such as heat exchangers, motors, and fan blades, preventing it from being designed into a compact and elegant form, thus hindering its integration into home décor. Currently, some commercial kitchen air conditioners deliver air to the kitchen through ductwork, but the uniformity of airflow from these ducts is often poor. Utility Model Content

[0003] This application provides an air outlet duct and an air conditioner, which solves the problem of poor uniformity of air outlet ducts in existing air conditioners.

[0004] The first aspect of this application provides an air outlet duct, comprising:

[0005] A first baffle, at least one first baffle is provided inside the air outlet duct, and each first baffle is provided with at least one first through hole;

[0006] The second baffle is located at the air outlet of the air outlet duct. At least one second through hole is provided at the second baffle, and the air from the air outlet duct passes through the second through hole before being blown out. The first surface of the second baffle faces the air outlet of the air outlet duct, and the second surface of the second baffle faces the first baffle.

[0007] The third baffle is located at the air outlet of the air outlet duct. The third baffle is located outside the second baffle. The air blown out from the second baffle passes through the third baffle and is then blown out.

[0008] In some embodiments of this application, the ratio of the cross-section of the first through hole of the first baffle to the cross-sectional area of ​​the corresponding first baffle gradually increases from the position near the air inlet duct to the position away from the air inlet duct.

[0009] In some embodiments of this application, at least a portion of the outer periphery of each first baffle contacts the inner side of the duct wall of the air outlet.

[0010] In some embodiments of this application, the shape of the cross-section of each first baffle along a preset plane is the same as the shape of the cross-section of the duct wall along the preset plane; wherein, the preset plane is a plane perpendicular to the extension direction of the duct.

[0011] In some embodiments of this application, there are multiple first baffles, and the multiple first baffles are parallel to each other.

[0012] In some embodiments of this application, the density of the first baffle gradually decreases in the direction from the air outlet position near the air inlet duct to the air outlet position away from the air inlet duct.

[0013] In some embodiments of this application, each first baffle is perpendicular to the extension direction of the air outlet duct.

[0014] In some embodiments of this application, the first baffle has a third side facing the air outlet;

[0015] The third side is spaced apart from the second baffle, and a uniform airflow gap is formed between the third side and the second baffle.

[0016] In some embodiments of this application, the third side is arranged parallel to and opposite to the second baffle, and the width of the uniform air gap between the multiple first baffles and the second baffles is the same or approximately the same.

[0017] In some embodiments of this application, the first baffle has a plurality of first through holes arranged in multiple rows and columns; the width of the uniform air gap is greater than or equal to the width between two adjacent first through holes.

[0018] A second aspect of this application provides an air conditioner, including the air outlet duct as described above.

[0019] This application achieves three levels of uniform airflow by installing a first baffle, a second baffle, and a third baffle at the air outlet duct. This improves the uniformity of the air blown out of the air outlet duct and makes the air feel almost windless, thus enhancing the user experience.

Detailed Implementation

[0040] In related technologies, traditional household wall-mounted air conditioners are all divided into indoor and outdoor units. However, regardless of the type of model, because the indoor unit contains core components such as heat exchangers, motors, and fan blades, its external size cannot be designed to be exquisite and compact, thus making it difficult to integrate well with home decoration environments. Currently, some commercial kitchen air conditioners deliver air to the kitchen through ducts, but the uniformity of airflow from the ducts in some commercial kitchen air conditioners is poor.

[0041] This application achieves three levels of uniform airflow by installing a first baffle, a second baffle, and a third baffle at the air outlet duct. This improves the uniformity of the air blown out of the air outlet duct and makes the air feel almost windless, thus enhancing the user experience.

[0042] In the description of this embodiment, it should be understood that the terms "length", "width", "height", "up", "down", "left", "right", "vertical", "horizontal", "bottom", "inner", "outer", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0043] Reference Figure 1-12 As shown, this embodiment discloses an air conditioner 100, which may include a body 200 and at least one air duct 300. The body 200 may include a housing and an evaporator disposed within the housing.

[0044] One end of the air supply duct 300 is connected to the body 200, and the other end of the air supply duct 300 is used to extend to the target space 400. An air inlet duct 310 and a return air duct are provided inside the air supply duct 300.

[0045] The air inlet end of the air inlet duct 310 is connected to the air outlet end of the evaporator, and the air outlet end of the air inlet duct 310 can discharge air to the target space 400; the air inlet end of the return air duct can be connected to the target space 400, and the air outlet end of the return air duct is connected to the air inlet end of the evaporator. The gas after heat exchange in the evaporator flows into the target space 400 through the air inlet duct 310, and the gas in the target space 400 enters the evaporator inside the casing 210 through the return air duct.

[0046] As one embodiment, the housing 200 includes a compressor (not shown) and a condenser (not shown), both of which are connected to the compressor (not shown).

[0047] Specifically, the air conditioner 100 in this embodiment may include a body 200 and at least one air supply duct 300. The body 200 may include an evaporator, a condenser, and a compressor, meaning that the body 200 includes the components of a conventional indoor and outdoor unit of an air conditioner 100. The air supply duct 300 in this embodiment, through an intake air duct and a return air duct, achieves the purpose of transporting gas from the body 200 to the target space 400, while simultaneously returning gas from the target space 400 back to the body 200. In other words, the air conditioner 100 in this embodiment places the evaporator, condenser, and compressor of a conventional indoor and outdoor unit in the same machine, transporting gas to the target space 400 only through the air supply duct 300. This effectively reduces the size of the indoor unit. Furthermore, since the indoor unit only contains the air supply duct 300 and lacks components such as an evaporator 220, the air conditioner 100 operates quietly within the target space 400, improving the user experience.

[0048] This application discloses a small-sized ducted air conditioner 100 with return air, which externalizes the core components of a traditional air conditioner 100, such as the heat exchanger, and delivers air through an air supply duct 300. In addition, the air supply duct 300 can be made into a small volume, thereby achieving integration into the home.

[0049] As one embodiment, a unit 200 in this embodiment may be equipped with one air supply duct 300. Of course, in other embodiments, a unit 200 may be equipped with multiple air supply ducts 300.

[0050] The air supply duct 300 in this embodiment may include a wall-penetrating section 350, which is used to pass through the cavity so that the end of the air supply duct 300 extends into the target space 400.

[0051] like Figure 1-12As shown, in this embodiment of the application, each air supply duct 300 is provided with an air outlet duct 500 at its end, which is connected to the air inlet duct 310. The extension direction of the air outlet duct 500 is parallel to the air outlet direction of the air inlet duct 310. An air outlet 510 is provided at the air outlet duct 500. The gas in the air inlet duct 310 flows into the air outlet duct 500 and is blown out from the air outlet 510.

[0052] Specifically, in this embodiment, an air outlet duct 500 is provided at the end of the air supply duct 300. When the gas is delivered to the target space 400 by the air supply duct 300, it is then blown out through the air outlet duct 500. The position and direction of the gas flow can be controlled by the air outlet duct 500.

[0053] Specifically, in this embodiment, the direction in which the air outlet duct 500 extends is parallel to the direction of air outlet, which can minimize the loss of gas energy.

[0054] In addition, the cross-sectional area of ​​the outlet duct 500 in this embodiment is larger than the cross-sectional area of ​​the end of the supply duct 300, so as to avoid gas energy loss and turbulence.

[0055] Specifically, in this embodiment, the air outlet 510 is located on the side wall of the air outlet duct 500, which is parallel to the extension direction. This ensures that the direction of the final blown gas is perpendicular to the extension direction of the air outlet duct 500.

[0056] Of course, in other embodiments, the air outlet 510 and the air outlet direction can be adaptively adjusted to meet different air outlet requirements.

[0057] In this embodiment, the sidewall is installed on the target object 600 to be installed, so that the air outlet 500 is exposed on the surface of the air outlet 510 when installed on the target object. Furthermore, the plane containing the air outlet 510 forms a continuous surface with the sidewall surface 601 of the target object 600 located on at least one side of the air outlet 510.

[0058] Specifically, when the air supply duct 300 includes a main pipe and branch pipes, each branch pipe that delivers air to the target space 400 is connected to an air outlet duct 500 at its end.

[0059] This application provides an air conditioner, including an air outlet duct 500, which is used to improve the uniformity of the air outlet of the air conditioner.

[0060] The air outlet duct includes a first baffle 520, a second baffle 530, and a third baffle 540.

[0061] As a specific embodiment of this application, the air outlet duct 500 of this embodiment is provided with at least one first baffle 520 that is substantially perpendicular to the extension direction of the air outlet duct 500. Each first baffle 520 is provided with at least one first through hole 521. At least part of the gas in the air outlet duct 500 passes through the first through hole 521 of the first baffle 520 and is then blown out from the air outlet 510.

[0062] Specifically, in this embodiment, at least one first baffle 520 is provided inside the air outlet duct 500. The first baffle 520 can block the gas in the air outlet duct 500, so as to prevent most or almost all of the gas in the air outlet duct 500 from being blown to the end of the air outlet duct 500 and then blown out from the air outlet 510, thereby avoiding uneven air outlet.

[0063] Preferably, in this embodiment, a plurality of first baffles 520 are provided inside the air outlet duct 500, and the plurality of first baffles 520 are arranged at intervals along the extension direction of the air outlet duct 500.

[0064] Specifically, by setting multiple first baffles 520 inside the air outlet duct 500 along its extension direction, the air volume blown out from the air outlet 510 can be further optimized, thereby further improving the uniformity of the airflow.

[0065] As a specific embodiment of this application, at least a portion of the outer periphery of the first baffle 520 is in contact with the inner wall of the air outlet duct 500, thus ensuring that all the gas flowing through the first baffle 520 passes through the first through hole 521 of the first baffle 520 before flowing to the rear.

[0066] Specifically, the outer periphery of each first baffle 520 contacts the side wall of the air outlet duct 500 where the non-air outlet is located.

[0067] Specifically, the cross-sectional shape of the first through hole 521 in this embodiment can be circular, elliptical, square, or other shapes. Preferably, the shape of the first through hole 521 in this embodiment is circular.

[0068] Preferably, all the first baffles 520 in this embodiment are arranged in parallel to each other.

[0069] Preferably, in this embodiment, all the first baffles 520 are perpendicular to the extension direction of the air outlet duct 500, and the shape of all the first baffles 520 is consistent with the cross-sectional shape of the side wall of the air outlet duct 500.

[0070] At least a portion of the outer periphery of each first baffle 520 contacts the inner side of the pipe wall of the air outlet duct 500, which helps to reduce or eliminate the gap between the first baffle 520 and the pipe wall of the air outlet duct 500, thereby enhancing the sealing performance of the air outlet duct 500.

[0071] The shape of the cross-section of each first baffle 520 along the preset plane is the same as the shape of the cross-section of the duct wall of the air outlet duct 500 along the preset plane, which facilitates the production, manufacturing and installation of the first baffle 520. The preset plane is a plane perpendicular to the extension direction of the air outlet duct 500.

[0072] Specifically, in this embodiment, the cross-sectional shape of the air outlet duct 500 is triangular, and the cross-sectional shape of the first baffle 520 is also triangular.

[0073] As a specific embodiment of this application, the proportion of the cross-section of the first through hole 521 of the first baffle 520 to the total cross-sectional area of ​​the first baffle 520 gradually increases from the position of the air inlet duct 310 to the position away from the air inlet duct 310.

[0074] Specifically, the wind speed is higher near the air inlet duct 310 and lower further away. This design ensures that the wind speed of the air blown out by the air outlet duct 500 is similar near and near the air inlet duct 310, resulting in good uniformity of the blown air and improving the user experience.

[0075] Specifically, the cross-sectional area of ​​the first through hole 521 of the first baffle 520 in this embodiment can be changed by changing the number of first through holes 521 or by changing the cross-sectional area of ​​each first through hole 521.

[0076] As a specific embodiment of this application, the density of the first baffle 520 in this embodiment gradually decreases in the direction from the position close to the air inlet duct 310 to the position far away from the air inlet duct 310.

[0077] Specifically, in this embodiment, the density of the first baffles 520 near the air inlet duct 310 is set to be large, while the density of the first baffles 520 far from the air inlet duct 310 is set to be small. This makes the airflow near the air inlet duct 310 and the airflow far from the air inlet duct 310 have similar speeds, thereby making the uniformity of the gas blown out of the air outlet 510 good.

[0078] As a specific embodiment, the density of the first baffle 520 set at the air outlet duct 500 and the cross-sectional area of ​​the first through hole 521 at the first baffle 520 can be designed according to the situation, so that the uniformity of the gas blown out of the air outlet 510 of the air outlet duct 500 is good.

[0079] More specifically, the diameter of the first through hole 521 at the first baffle 520 in this embodiment is adjustable. By changing the total cross-section of the first through hole 521 at each first baffle 520, the ratio of the total cross-sectional area of ​​the first through hole 521 to the cross-section of the first baffle 520 can be changed, thereby further improving the uniformity of the air output.

[0080] In another embodiment, the first baffle 520 of this embodiment can be set with different areas at different distances from the air inlet duct 310, so as to further increase the uniformity of the air outlet.

[0081] As a specific embodiment of this application, such as Figure 3-6 As shown, in this embodiment, a second baffle 530 is provided at the air outlet 510 of the air outlet duct 500. The second baffle 530 is provided with at least one second through hole 531, through which the gas from the air outlet duct 500 is blown out.

[0082] Specifically, in this embodiment, a first through hole 521 of a first baffle 520 is provided at the air outlet duct 500, and a second baffle 530 is provided at the air outlet 510, with a second through hole 531 provided at the second baffle 530, to further increase the uniformity of air outlet from the air outlet duct 500.

[0083] As a specific embodiment of this application, a third baffle 540 is also provided at the air outlet 510 of the air outlet duct 500 in this embodiment. The third baffle 540 is located outside the second baffle 530 so that the gas blown out from the second baffle 530 passes through the third baffle 540 and is then blown out.

[0084] Specifically, in this embodiment, the gas blown out from the second baffle 530 passes through the third baffle 540 before being blown out again, further improving the uniformity of the airflow.

[0085] Specifically, the third baffle 540 in this embodiment can be designed as a filter structure; the filter structure of this embodiment can be obtained by setting a filter screen in the center of the frame structure. As another specific embodiment, the third baffle 540 in this embodiment can be designed as a horizontal strip-shaped grid structure (e.g., Figure 3 and Figure 4 As shown), the direction of airflow can be adjusted by changing the number and direction of the grid structure. As another specific embodiment, the third baffle 540 of this embodiment can also be designed as a perforated partition structure (e.g., Figure 5 and Figure 6 As shown in the figure, the size and distribution of the holes on the partition can be designed according to actual conditions. Specifically, in this embodiment, the holes on the partition have a larger diameter in the middle and smaller diameters on both sides.

[0086] Specifically, in this embodiment, a first baffle 520, a second baffle 530, and a third baffle 540 are provided at the air outlet duct 500. The three components achieve three-level uniform airflow, resulting in good uniformity of the gas blown out from the air outlet duct 500 and almost no wind sensation, thus improving the user experience.

[0087] As a specific embodiment of this application, such as Figure 7 and Figure 8 As shown, in this embodiment, the air outlet duct 500 is also provided with a baffle plate 550 and air guiding mechanisms 560 located on both sides of the baffle plate 550 at the air outlet 510. The air guiding mechanism 560 guides the gas blown out of the air outlet 510 to the side away from the baffle plate 550.

[0088] Specifically, in this embodiment, a baffle plate 550 and a guide mechanism 560 are provided at the air outlet 510 of the air outlet duct 500. The baffle plate 550 is located in the middle of the air outlet 510, while the guide mechanism 560 guides the air blown out of the air outlet 510 to a position away from the middle, thereby preventing the air in the air blown out of the air outlet 510 from blowing directly at the user, thereby improving the user experience.

[0089] Specifically, the air guiding mechanism 560 of this embodiment may include at least one air guiding plate 561, which is rotatable. Multiple air guiding plates 561 may be arranged in parallel. Multiple air guiding plates 561 may rotate individually or in conjunction to meet different usage requirements.

[0090] Specifically, in this embodiment, the air guide plate 561 of the air guide mechanism 560 can be rotatably connected to the wall of the air outlet duct 500, and the rotation axis of the air guide plate 561 is parallel to the extension direction of the air guide plate 561. Thus, the direction of the gas blown out from the air guide mechanism 560 can be controlled by controlling the rotation of the air guide plate 561.

[0091] Continue to refer to Figure 1-6 As shown, in some possible embodiments, the air outlet duct 500 includes multiple air outlet modules 501. By dividing the air outlet duct 500 into multiple modules, the flexibility of the air outlet duct 500 configuration can be improved. The multiple air outlet modules 501 arranged in sequence can expand the coverage area of ​​the blown gas, thereby improving the temperature uniformity of the target space 400.

[0092] For example, multiple air outlet modules 501 can be arranged sequentially along the extension direction of the air outlet module 501 to expand the coverage of the air outlet duct 500.

[0093] Furthermore, among the multiple air outlet modules 501, two adjacent air outlet modules 501 are detachably connected. The detachable connection facilitates the installation, removal, and replacement of the air outlet modules 501, helps reduce maintenance costs, and improves the scalability and flexibility of the air outlet duct 500.

[0094] Reference Figure 3 As shown, the air outlet module 501 includes an air outlet housing 503. The air outlet housings 503 of two adjacent air outlet modules 501 are snap-fitted together to improve the installation and disassembly efficiency of the air outlet module 501.

[0095] The air outlet housing 503 has a connecting vent 575. The connecting vents 575 of the two air outlet housings 503 are connected to each other so that gas can flow between the air outlet modules 501 through the connecting vent 575. This ensures that the airflow flows from the end of the air outlet duct 500 near the air inlet duct 310 to the end of the air outlet duct 500 away from the air inlet duct 310.

[0096] As mentioned above, the air outlet module 501 includes a first baffle 520. The first baffle 520 is disposed inside the air outlet housing 503 and is detachably connected to the air outlet housing 503. This arrangement facilitates the installation and removal of the first baffle 520 and improves the maintainability of the air outlet duct 500.

[0097] The air outlet housing 503 is provided with multiple mounting slots 573. The mounting slots 573 can be used to install the first baffle 520. The mounting slots 573 can limit the first baffle 520, reducing the use of fasteners for fixing the first baffle 520.

[0098] Some or all of the multiple mounting slots 573 can be used to accommodate the first baffle 520. The multiple mounting slots 573 are arranged sequentially at intervals along the extension direction of the air outlet housing 503. The position and number of the first baffle 520 can be adjusted according to actual needs, thereby optimizing the air outlet effect of the air outlet duct 500.

[0099] The first baffle 520 is detachably mounted in the mounting slot 573. It can be installed or removed via simple operations (such as pushing or sliding) without the need for additional tools. By placing the first baffles 520 in different mounting slots 573, the distance between adjacent first baffles 520 can be adjusted. This satisfies the airflow requirements of the target space 400, and the adjustment process is convenient and quick.

[0100] In the extending direction of the air outlet housing 503, multiple mounting slots 573 are arranged at equal intervals to avoid the first baffles 520 located in the multiple mounting slots 573 from overlapping, thereby avoiding the first baffles 520 from failing to block the gas in the air outlet duct 500, resulting in uneven air outlet of the air outlet duct 500.

[0101] In some possible implementations, the distance between two adjacent first baffles 520 gradually increases in the direction from the air outlet 510 near the air inlet duct 310 to the air outlet 510 away from the air inlet duct 310. This allows the airflow velocity near the air inlet duct 310 to be approximately the same as the airflow velocity away from the air inlet duct 310, thereby improving the uniformity of the gas blown out of the air outlet 510.

[0102] The air outlet housing 503 includes a first inner wall 571 and a second inner wall 572 connected to each other, and the first inner wall 571 and the second inner wall 572 have a certain angle. Through the first inner wall 571 and the second inner wall 572, the gas is guided to flow in the air inlet duct 310 along a certain path, thereby improving the airflow distribution.

[0103] The mounting groove 573 includes a first groove portion 5731 and a second groove portion 5732. The first groove portion 5731 is located on the first inner wall 571, and the second groove portion 5732 is located on the second inner wall 572. The first groove portion 5731 and the second groove portion 5732 are respectively arranged on the first inner wall 571 and the second inner wall 572, which can further restrict the movement of the first baffle 520 and enhance the stability of the first baffle 520 within the mounting groove 573.

[0104] The first side of the first baffle 520 can slide within the first groove 5731 along the extending direction of the first groove 5731, and the second side of the first baffle 520 can slide within the second groove 5732 toward the bottom surface of the second groove 5732. The first baffle 520 can be installed by sliding along the first groove 5731 or along the second groove 5732, so that the installation process of the first baffle 520 does not require the use of complex tools or cumbersome operations, which can improve the assembly efficiency of the air outlet module 501.

[0105] For example, the first groove 5731 extends in a direction that intersects with the extension direction of the second groove 5732, so that the first side of the first baffle 520 can be fixed in the first groove 5731 and the second side of the first baffle 520 can be fixed in the second groove 5732, reducing the use of fasteners for fixing the first baffle 520.

[0106] A fastener (not shown in the figure) is provided in the mounting slot 573, and the first baffle 520 is fixed to the air outlet housing 503 by the fastener. The fastener fixes the first baffle 520 to prevent the airflow from the air inlet duct 310 from acting on the first baffle 520, thereby preventing the first baffle 520 from changing position or becoming loose or falling off.

[0107] As mentioned above, the air outlet module 501 includes a second baffle 530, which can improve the uniformity of airflow from the air outlet duct 500. The second baffle 530 is connected to the air outlet housing 503 and is located on the side of the first baffle 520 near the air outlet 510, so that the airflow passes through the first baffle 520 and is then regulated by the second baffle 530, thereby further improving the uniformity of airflow from the air outlet duct 500.

[0108] For example, the second baffle 530 can be snapped into the air outlet housing 503 to improve the assembly efficiency of the air outlet module 501.

[0109] The first surface of the second baffle 530 faces the air outlet 510 of the air outlet housing 503, and the second surface of the second baffle 530 faces the plurality of first baffles 520. This ensures that the gas flows from the first baffle 520 to the second baffle 530 and is blown out after passing through the second baffle 530, reducing gas turbulence and improving the air outlet efficiency of the air outlet duct 500.

[0110] In some possible implementations, the first baffle 520 has a third side. The first side, the second side, and the third side are adjacent to each other. The third side faces the air outlet 510, enabling the first baffle 520 to guide the gas to flow towards the air outlet 510, thereby improving the air outlet efficiency of the air duct 500.

[0111] The third side is spaced apart from the second baffle 530, forming a uniform airflow gap between them. This arrangement allows the gas to flow from the end of the outlet duct 500 near the inlet duct 310 to the end away from the inlet duct 310 after entering the outlet duct 500, thus improving the uniformity of the gas blown out of the outlet duct 500.

[0112] The third side is arranged parallel to and opposite to the second baffle 530 to reduce the resistance to gas flow in the air outlet duct 500.

[0113] The uniform air gaps between the multiple first baffles 520 and the second baffles 530 have the same or approximately the same width, which can ensure that the airflow is subjected to a small resistance difference when passing through the uniform air gaps between the multiple first baffles 520 and the second baffles 530, thereby reducing airflow fluctuations and improving the air outlet efficiency of the air outlet duct 500.

[0114] The first baffle 520 has multiple first through holes 521. The first through holes 521 are arranged in multiple rows and columns to improve the uniformity of gas when passing through the first baffle 520 and avoid excessive or insufficient local airflow.

[0115] For example, multiple rows of first through holes 521 and multiple columns of first through holes 521 can be aligned and arranged separately, which facilitates the production of the first baffle 520. Adjacent rows of first through holes 521 in multiple rows can be staggered. Adjacent columns of first through holes 521 in multiple columns can also be staggered.

[0116] The gas entering the outlet duct 500 flows through the first baffle 520 to the end of the outlet duct 500 away from the inlet duct 310. If the width of the uniform air distribution gap is less than the width between two adjacent first through holes 521, there will be less gas at the end of the outlet duct 500 away from the inlet duct 310, resulting in poor uniformity of the gas blown out of the outlet duct 500. Therefore, the width of the uniform air distribution gap should be greater than or equal to the width between two adjacent first through holes 521 to avoid reducing the uniformity of the gas blown out of the outlet duct 500.

[0117] Along the length of the air outlet housing 503, the length of the second baffle 530 is the same as or approximately the same as the length of the air outlet housing 503, which can cover the air outlet 510 of the air outlet housing 503, thereby controlling the flow of gas and improving the uniformity of the gas blown out by the air outlet duct 500.

[0118] As mentioned above, the air outlet module 501 includes a third baffle 540, which is located on the side of the second baffle 530 away from the first baffle 520. The gas in the air outlet duct 500, after being blown out from the second baffle 530, further passes through the third baffle 540 before being blown out again, further improving the uniformity of the air outlet from the air outlet duct 500.

[0119] The third baffle 540 is arranged parallel to the second baffle 530, which helps to maintain the consistency of the gas flow direction when passing through the second baffle 530 and the third baffle 540, reduce the change of gas flow direction, and reduce the loss of gas flow energy.

[0120] Along the length of the air outlet housing 503, the length of the third baffle 540 is the same as or approximately the same as the length of the air outlet housing 503. This covers the air outlet 510 of the air outlet housing 503, thereby controlling the flow of gas and improving the uniformity of the gas blown out by the air outlet duct 500.

[0121] When the distance between the second baffle 530 and the third baffle 540 is greater than the width of the uniform air gap, the gas has enough space to diffuse and mix after passing through the second baffle 530, and then the gas flows through the third baffle 540, thereby improving the uniformity of the gas blown out of the air outlet duct 500.

[0122] This application achieves three levels of uniform airflow by setting a first baffle 520, a second baffle 530, and a third baffle 540 at the air outlet duct. This improves the uniformity of the air blown out of the air outlet duct and makes the air feel almost windless, thus enhancing the user experience.

[0123] As a specific embodiment of this application, such as Figure 1 and Figure 2 As shown, each air supply duct 300 in this embodiment is provided with an air outlet duct 500 at its end, which is connected to the air inlet duct 310. The extension direction of the air outlet duct 500 is parallel to the air outlet direction of the air inlet duct 310. An air outlet 510 is provided at the air outlet duct 500. The gas in the air inlet duct 310 flows into the air outlet duct 500 and is blown out from the air outlet 510.

[0124] Specifically, in this embodiment, an air outlet duct 500 is provided at the end of the air supply duct 300. When the gas is delivered to the target space 400 by the air supply duct 300, it is then blown out through the air outlet duct 500. The position and direction of the gas flow can be controlled by the air outlet duct 500.

[0125] Specifically, in this embodiment, the direction in which the air outlet duct 500 extends is parallel to the direction of air outlet, which can minimize the loss of gas energy.

[0126] In addition, the cross-sectional area of ​​the outlet duct 500 in this embodiment is larger than the cross-sectional area of ​​the end of the supply duct 300, so as to avoid gas energy loss and turbulence.

[0127] Specifically, in this embodiment, the air outlet 510 is located on the side wall of the air outlet duct 500, which is parallel to the extension direction. This ensures that the direction of the final blown gas is perpendicular to the extension direction of the air outlet duct 500.

[0128] Of course, in other embodiments, the air outlet 510 and the air outlet direction can be adaptively adjusted to meet different air outlet requirements.

[0129] Specifically, the main pipe can be connected to the air outlet duct 500 through a branch pipe, and the airflow is delivered to the air outlet duct 500 through the main pipe and the branch pipe in sequence.

[0130] Specifically, the main pipe can be connected to the air outlet duct 500 through multiple branch pipes, and the multiple branch pipes can be set at intervals along the extension direction of the air outlet duct 500.

[0131] like Figure 9As shown in a specific embodiment of this application, the air outlet duct 500 has a mounting surface 505 and an air outlet surface 502 connected to the mounting surface 505, the air outlet surface 502 forming an air outlet 510. The mounting surface 505 can be used to fix the air outlet duct 500 to a target object, the air outlet surface 502 can be a surface with an air outlet 510, the air outlet surface 502 is used to evenly blow airflow from the air outlet duct 500, and the air outlet 510 is a channel for airflow to flow out from the air outlet duct 500. The air outlet surface 502 is connected to the mounting surface 505 to form the overall structure of the air outlet duct 500, ensuring the stability of the air outlet duct 500.

[0132] Specifically, in a plane perpendicular to the air outlet surface 502 and the mounting surface 505, the angle between the plane containing the air outlet surface 502 and the plane containing the mounting surface 505 can be less than or equal to 90 degrees. The plane perpendicular to the air outlet surface 502 and the mounting surface 505 can be the viewing angle when observing the air outlet duct 500 from the side, such as... Figure 9 As shown, when the cross-section of the air outlet duct 500 is triangular, the plane containing its hypotenuse is the air outlet surface 502, and the plane containing its two right-angled sides is the mounting surface 505. The two mounting surfaces 505 are respectively attached to the top and side wall of the room (i.e. the target object). The angle between the plane containing the air outlet surface 502 and the plane containing the mounting surface 505 is less than 90 degrees.

[0133] When the mounting surface 505 is fixed to the target object by the mounting bracket, and the angle between the plane containing the air outlet surface 502 and the plane containing the mounting surface 505 is less than 90 degrees, both ends of the air outlet surface 502 can extend out of the mounting surface 505 and abut against the top and side wall of the target object, respectively. Figure 10 As shown, this makes the connection between the air duct 500 and the target object smoother, reducing gaps during the connection.

[0134] Specifically, the number of mounting surfaces 505 can be multiple, such as... Figure 10 As shown, the multiple mounting surfaces 505 may include a first mounting surface 5051 and a second mounting surface 5052. The air outlet duct 500 can be fixed to the target object through these multiple mounting surfaces 505, increasing the stability of the air outlet duct 500. The first mounting surface 5051 can be the main fixing surface of the air outlet duct 500, connecting to the main contact surface of the target object, such as a ceiling. The second mounting surface 5052 can be the auxiliary fixing surface of the air outlet duct 500, connecting to the secondary contact surface of the target object, such as a side wall.

[0135] More specifically, in a plane perpendicular to the air outlet surface 502 and the mounting surface 505, the first mounting surface 5051 can be connected to the first end of the air outlet surface 502, and the second mounting surface 5052 can be connected to the second end of the air outlet surface 502. For example... Figure 9As shown, when the cross-section of the air outlet duct 500 is triangular, the surface containing its hypotenuse is the air outlet surface 502, the upper end of the hypotenuse is the first end of the air outlet surface 502, the lower end of the hypotenuse is the second end of the air outlet surface 502, the first end of the air outlet surface 502 is connected to the mounting surface 505 fixed on the top, and the second end of the air outlet surface 502 is connected to the mounting surface 505 fixed on the side wall.

[0136] Specifically, the first mounting surface 5051 and the second mounting surface 5052 can be perpendicular or approximately perpendicular. When the air outlet duct 500 needs to be fixed to two mutually perpendicular or approximately perpendicular target surfaces, such as a ceiling and a wall, the first mounting surface 5051 and the second mounting surface 5052 can be set perpendicular or approximately perpendicular.

[0137] Specifically, the first mounting surface 5051 and the second mounting surface 5052 can be parallel or approximately parallel. When a mounting groove is provided on the side wall of the target object, and the cross-section of the air outlet duct 500 can be quadrilateral, the first mounting surface 5051 and the second mounting surface 5052 can be set parallel or approximately parallel. The first mounting surface 5051 is connected to the inner upper surface of the mounting groove, and the second mounting surface 5052 is connected to the inner lower surface of the mounting groove, thereby embedding the air outlet duct 500 into the mounting groove, with only the air outlet surface 502 exposed.

[0138] Specifically, the air outlet housing may have a first transition surface 504, which may connect a first mounting surface 5051 and a second mounting surface 5052. The first transition surface 504 is parallel or approximately parallel to the air outlet surface 502. Figure 11 As shown, when the first mounting surface 5051 and the second mounting surface 5052 are parallel or approximately parallel, the first end of the first transition surface 504 is connected to the first mounting surface 5051, and the second end of the first transition surface 504 is connected to the second mounting surface 5052. The first transition surface 504 is parallel or approximately parallel to the air outlet surface 502. By connecting the first mounting surface 5051 and the second mounting surface 5052 through the first transition surface 504, the air outlet duct 500 can be tightly fitted to the inner wall of the mounting groove.

[0139] Specifically, the air outlet housing may have a second transition surface (not shown in the figure), which is located at the end of the air outlet duct 500 to ensure the stability and aesthetics of the air outlet duct 500 at the end.

[0140] Specifically, when the air outlet duct 500 is installed on the side wall surface of the target object via the mounting surface 505, the angle between the air outlet surface 502 and the side wall surface of the target object is greater than 90 degrees. For example... Figure 9 As shown, this allows the exhaust duct 500 to transition smoothly onto the target object, resulting in a more aesthetically pleasing appearance when the exhaust duct 500 is installed on the target object.

[0141] Specifically, when the air outlet duct 500 is installed on the side wall surface of the target object through the mounting surface 505, the air outlet surface 502 and the side wall surface of the target object are located on the same plane.

[0142] As a specific embodiment of this application, among the plurality of mounting surfaces 505, at least one mounting surface 505 can be used to connect to an air supply duct so that the airflow in the air supply duct can flow to the air outlet duct 500.

[0143] Therefore, those skilled in the art should recognize that although many exemplary embodiments of this application have been shown and described in detail herein, many other variations or modifications conforming to the principles of this application can be directly determined or derived from the disclosure of this application without departing from the spirit and scope of this application. Thus, the scope of this application should be understood and construed as covering all such other variations or modifications.
