Air conditioner

Abstract

The present application relates to the technical field of air conditioners. Provided is an air conditioner. The air conditioner of the present application may comprise a main body and at least one air-supply duct. The main body may comprise an evaporator, a condenser, a compressor, and a first fan, that is, the main body incorporates components of an indoor unit and an outdoor unit of a traditional air conditioner. The air-supply duct of the present application delivers air from inside the main body to a target space through a supply-air passage and returns air from the target space to the main body through a return-air passage. By delivering air to the target space only through the air-supply duct, the overall size of indoor equipment can be effectively reduced. Moreover, since only the air-supply duct is arranged indoors without equipment such as an evaporator and a fan, the air conditioner produces low noise when blowing air into the target space, thereby improving user experience.

[0001] This application relates to the field of air conditioning technology, and more particularly to 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. Therefore, it cannot be easily integrated into home décor. Currently, some commercial kitchen air conditioners deliver air to the kitchen through ductwork, but due to the large size of these ducts and the lack of return air, they are unsuitable for home environments and cannot be integrated with furniture. Summary of the Invention

[0005] The body includes a housing and an evaporator disposed in the housing;

[0006] An air supply duct, one end of which is connected to the body, and the other end of which can be extended into the target space, and an air inlet duct and an air return duct are provided inside the air supply duct;

[0007] The air inlet end of the air inlet duct is connected to the air outlet end of the evaporator, and the air outlet end of the air inlet duct can discharge air to the target space; the air inlet end of the return air duct can be connected to the target space, and the air outlet end of the return air duct is connected to the air inlet end of the evaporator.

[0060] 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.

[0061] As a specific embodiment of this application, as shown in Figures 1 to 4, this embodiment discloses an air conditioner 100, wherein the air conditioner 100 may include a body 200 and at least one air supply duct 300, wherein the body 200 may include a housing 210 and an evaporator 220 disposed within the housing 210.

[0062] 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 320 are provided inside the air supply duct 300.

[0063] The air inlet end of the air inlet duct 310 is connected to the air outlet end of the evaporator 220, 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 320 can be connected to the target space 400, and the air outlet end of the return air duct 320 is connected to the air inlet end of the evaporator 220. The gas after heat exchange in the evaporator 220 flows into the target space 400 through the air inlet duct 310, and the gas in the target space 400 enters the evaporator 220 inside the casing 210 through the return air duct 320.

[0064] In one embodiment, the housing 200 includes a compressor 240 and a condenser 230, with both the evaporator 220 and the condenser 230 connected to the compressor 240.

[0065] 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 220, a condenser 230, and a compressor 240, meaning 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 310 and a return air duct 320, 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 220, condenser 230, and compressor 240 from both the indoor and outdoor units into 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 not the evaporator 220 or other components, the air conditioner 100 operates quietly within the target space 400, improving the user experience.

[0066] 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.

[0067] As one embodiment, as shown in Figures 5 and 6, a unit 200 in this embodiment can be equipped with one air supply duct 300. Of course, in other embodiments, a unit 200 can be equipped with multiple air supply ducts 300.

[0068] More specifically, as shown in Figure 6, each air supply duct 300 may include a main pipe 330 and at least one branch pipe 340. One end of each branch pipe 340 is connected to the main pipe 330, and the other end is connected to the corresponding target space 400 to supply air to the target space 400.

[0069] When a unit 200 is equipped with one air supply duct 300, and there are multiple target spaces 400, a main pipe 330 and multiple branch pipes 340 can be used to supply air to different target spaces 400 (as shown in Figure 6). When a unit 200 is equipped with multiple air supply ducts 300, and there are multiple target spaces 400, each air supply duct 300 can include one main pipe 330, and the number of air supply ducts 300 is matched according to the number of target spaces 400 and the number of air supply ducts 300. Each air supply duct 300 can supply air to one of the target spaces 400 (as shown in Figure 5).

[0070] As another specific embodiment of this application, the air supply duct 300 of 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. The ratio of the cross-sectional area of ​​the wall-penetrating section 350 to the power of the air conditioner 100 is less than or equal to 57.37 cm2 / kw, wherein the cross-sectional area of ​​the wall-penetrating section 350 is less than or equal to 200 cm2.

[0071] Specifically, in this embodiment, the ratio of the cross-sectional area of ​​the wall-penetrating section 350 of the air supply duct 300 to the power of the air conditioner 100 is less than or equal to 57.37 cm² / kW. For example, in this embodiment, when the power of the air conditioner 100 in the wall-penetrating section 350 is 1.5 horsepower or higher, the upper limit of the cross-sectional area of ​​the corresponding wall-penetrating section 350 is 200 cm². When the power of the air conditioner 100 is lower, the cross-sectional area of ​​its wall-penetrating section 350 can be even smaller. Specifically, the ratio of the cross-sectional area to the power of the wall-penetrating section 350 of the air supply duct 300 in this embodiment is designed because, on the one hand, power has a significant limitation on the cross-sectional area; the cross-sectional area of ​​the air supply duct 300 at a certain power is fixed. On the other hand, it is subject to existing laws and regulations, and the cross-sectional area cannot be infinitely large.

[0072] Specifically, the cross-sectional shape of the wall-penetrating section 350 in this embodiment can be circular, square, or other shapes. Furthermore, most general wall-penetrating holes are circular; therefore, the wall-penetrating section 350 in this embodiment is preferably circular. Preferably, the shape of the wall-penetrating section 350 of the air conditioner 100 in this embodiment is circular, and the cross-sectional area of ​​the wall-penetrating section 350 is less than or equal to 200 cm², that is, the diameter is less than or equal to 160 mm.

[0073] Specifically, in this embodiment, each air supply duct 300 needs to pass through the wall to enter the target space 400. Therefore, each air supply duct 300 in this embodiment may include a wall-penetrating section 350. In this embodiment, the wall-penetrating section 350 may be circular, and its diameter is less than or equal to 160mm. Furthermore, the diameter of the wall-penetrating section is designed to match the power of the air conditioner 100, which is greater than 1.5 horsepower. In this way, the power requirements of the air conditioner 100 are met, while also satisfying the requirement that the wall-penetrating hole cannot be too large.

[0074] As a specific embodiment of this application, as shown in Figures 7-10, each main pipe 330 and branch pipe 340 of this embodiment may include a pipe body 360 and a first partition 370. The first partition 370, located inside the pipe body 360, extends in a direction parallel to the extension direction of the pipe body 360, dividing the pipe body 360 into an air inlet duct 310 and a return air duct 320.

[0075] More specifically, in this embodiment, the cross-sectional areas of the air inlet duct 310 and the air return duct 320 are the same. This ensures that the air volume of the air inlet and the air return is equivalent.

[0076] When the air supply duct 300 includes a main pipe 330 and a branch pipe 340, the air inlet duct 310 of the main pipe 330 and the air inlet duct 310 of the branch pipe 340 are connected, and the return air duct 320 of the main pipe 330 and the return air duct 320 of the branch pipe 340 are connected.

[0077] Specifically, when the air supply duct 300 in this embodiment includes a main pipe 330 and a branch pipe 340, the wall penetration section 350 is located at the branch pipe 340.

[0078] More specifically, in this embodiment, the cross-section of the air supply duct 300 at the wall penetration section 350 can be designed as circular, while the ducts at other locations can be designed as circular (as shown in Figure 9) or other shapes. For example, the duct between the wall penetration section 350 and the unit body 200 can be designed as square, such as rectangular (as shown in Figure 10) or square. This design makes the air supply duct 300 more aesthetically pleasing and easier to install when it is outside the wall, and it also better matches the wall penetration hole at the wall penetration section 350.

[0079] As a specific embodiment of this application, the air supply duct 300 in this embodiment is provided with a heat insulation layer (not shown in the figure) on its wall. The heat insulation layer can keep the gas inside the air supply duct 300 warm and isolate it from the ambient temperature, reducing the influence of the external environment on the temperature of the transported gas during the transport process.

[0080] As a specific embodiment of this application, as shown in Figures 9 and 10, the air supply duct 300 of this embodiment is formed by one or more duct units. When the air supply duct 300 is formed by connecting multiple duct units together, the multiple duct units are interlocked and spliced ​​together to form the entire duct. Specifically, a retaining ring 390 (as shown in Figure 9) is provided at the connection position between the duct units. The retaining ring 390 interlocks and seals the ends of the duct units on both sides.

[0081] As a specific embodiment of this application, as shown in Figures 11 and 12, 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] Of course, in other embodiments, the air outlet 510 and the air outlet direction can be adaptively adjusted to meet different air outlet requirements.

[0087] Specifically, when the air supply duct 300 includes a main pipe 330 and a branch pipe 340, each branch pipe 340 that delivers air to the target space 400 is connected to an air outlet duct 500 at its end.

[0088] As a specific embodiment of this application, as shown in Figures 13-16, the air outlet duct 500 of this embodiment is provided with at least one first baffle 520 that is substantially perpendicular to the extending 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.

[0089] Specifically, in this embodiment, at least one first baffle 520 is provided inside the air outlet duct 500 to block the gas inside the air outlet duct 500, thereby preventing most or almost all of the gas inside 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, thus avoiding uneven air outlet.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] Preferably, all the first baffles 520 in this embodiment are arranged in parallel to each other.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] Specifically, since the wind speed is higher near the air inlet duct 310 and lower far from the air inlet duct 310, this design ensures that the wind speed of the gas blown out by the air outlet duct 500 is similar near the air inlet duct 310 and far from the air inlet duct 310, resulting in good uniformity of the blown gas and improving the user experience.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] As a specific embodiment of this application, as shown in Figures 13-16, a second baffle 530 is provided at the air outlet 510 of the air outlet duct 500 in this embodiment. The second baffle 530 has at least one second through hole 531, through which the gas from the air outlet duct 500 passes before being blown out.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] Specifically, the third baffle 540 in this embodiment can be designed as a filter structure (as shown in Figures 11 and 12). The filter structure of this embodiment is 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 (as shown in Figures 13 and 14). The direction of airflow can be adjusted by changing the number and direction of the grid structure. As yet another specific embodiment, the third baffle 540 in this embodiment can also be designed as a perforated partition structure (as shown in Figures 15 and 16), and 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.

[0111] 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.

[0112] As a specific embodiment of this application, as shown in Figures 17 and 18, the air outlet duct 500 of this embodiment is further 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 mechanisms 560 guide the gas blown out of the air outlet 510 in a direction away from the baffle plate 550.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] Referring again to Figures 11-16, 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.

[0117] 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.

[0118] 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.

[0119] Referring to Figure 13, 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] The third side is set parallel to and opposite to the second baffle 530 to reduce the resistance to gas flow in the air outlet duct 500.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] As a specific embodiment of this application, as shown in FIG11, the air outlet duct 500 of this embodiment may include a plurality of interconnected and communicating air outlet modules 501. Adjacent air outlet modules 501 are snap-fitted together. Each air outlet module 501 may be provided with a first baffle 520 extending vertically. A second baffle 530 and a third baffle 540 are provided at the air outlet 510 of each air outlet module 501. A baffle plate 550 and an air guide mechanism 560 are also provided at the air outlet 510 of each air outlet module 501.

[0148] As a specific embodiment of this application, as shown in FIG19 or 20, the air outlet duct 500 of this embodiment may further include a sidewall 570, which is installed on the target object 600 to be installed, so that the air outlet duct 500 exposes the surface where the air outlet 510 is located when installed on the target object. Furthermore, the plane where the air outlet 510 is located 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.

[0149] Specifically, the target object in this embodiment can be a specific object in the target space 400, such as a room or a cabinet. As one embodiment, when the air outlet duct 500 is installed on the target object, the air outlet 510 of the air outlet duct 500 is exposed, and the plane where the air outlet 510 is located forms a continuous surface with the side wall surface 601 of the target object 600 located on at least one side of the air outlet 510 (as shown in Figures 19, 21 and 22). This makes the air outlet duct 500 and the target object 600 not look abrupt from the outside, thus making the appearance of the air outlet duct 500 when installed on the target object 600 aesthetically pleasing.

[0150] Specifically, in this embodiment, the plane where the air outlet 510 of the air outlet duct 500 is located can form a substantially continuous surface with the exposed surface 601 of the target object 600 located on one side of the air outlet 510.

[0151] For example, when the cross-section of the air outlet duct 500 is triangular (as shown in Figure 19), and the target object is the interior wall of the room, it can be set at the position between the top and side wall of the room, with only the air outlet 510 exposed. The plane where the air outlet 510 is located forms a continuous zigzag surface with the surface of the ceiling and the side wall.

[0152] When the cross-section of the air outlet duct 500 is quadrilateral, as shown in Figure 20, two of its sides can be installed with the top and side wall of the target object 600, while the other two sides can have an air outlet 510 set at one place or both places.

[0153] Preferably, when the cross-section of the air outlet duct 500 is quadrilateral, as shown in Figures 21 and 22, the plane where the air outlet 510 is located and the side wall surface 601 of the target object 600 located around the air outlet 510 form a substantially continuous surface.

[0154] More preferably, as shown in Figure 22, the plane where the air outlet 510 is located in this embodiment is on the same plane as the side wall surface 601 of the target object 600 near the air outlet 510. In this case, an installation groove needs to be opened at the target object 600 to embed the air outlet duct 500 into the installation groove, with only the air outlet surface 502 or the air outlet 510 exposed.

[0155] More specifically, the continuity described in this embodiment does not mean that the air outlet or air outlet surface and the outside of the side wall must be strictly on the same plane, curved surface, or folded surface. When the air outlet 510 or air outlet surface 502 protrudes or is recessed within an area of ​​about 1-2 cm outside the side wall, it can also be regarded as a continuous surface or the same plane.

[0156] As a specific embodiment of this application, as shown in Figures 23 and 24, an installation structure is provided at the side wall 570 of the air outlet duct 500 in this embodiment. The installation structure may include a magnetic structure or a snap-fit ​​structure to attract or snap with the mounting bracket 580 at the target object 600, thereby allowing the air outlet duct 500 to be installed at the target object 600. Specifically, one mounting bracket 580 can install one air outlet module 501, or multiple air outlet modules 501.

[0157] Specifically, as shown in Figure 24, a mounting bracket 580 in this embodiment is provided with a snap-fit ​​structure 581, and a structure corresponding to and cooperating with the snap-fit ​​structure 581 is provided on the side wall 570 of the air outlet duct 500. When installing the air outlet duct 500, the mounting bracket 580 can be fixed to the target object 600 first, and then the air outlet duct 500 can be snapped into the snap-fit ​​structure 581 of the mounting bracket 580. The mounting bracket 580 in this embodiment can simultaneously install two air outlet modules 501.

[0158] Of course, as in other embodiments, the connection between the mounting bracket 580 and the mounting structure can be in other forms such as snap-fit. The air outlet duct 500 cooperates with the mounting bracket 580 on the target object 600, so that the air outlet duct 500 can be quickly and flexibly installed on the target object 600.

[0159] As a specific embodiment of this application, the cross-section of the air outlet duct 500 is a right-angled triangle, with the hypotenuse being the outlet surface and the two right-angled sides being the mounting or contact surfaces. The two right-angled sides are respectively attached to the top and side walls of the room (i.e., the target object), with only the surface containing the air outlet 510 exposed. Mounting components can also be installed on the right-angled sides for installation on the top and / or side walls.

[0160] More specifically, each mounting bracket 580 in this embodiment may include a connecting portion 582 and a mounting portion 583. The connecting portion 582 connects the mounting portion 583 and connects the mounting bracket 580 to the target object 600 through the connecting portion 582. The mounting portion 583 cooperates with the mounting structure to connect the air outlet duct 500 to the mounting bracket 580.

[0161] The air supply duct 300 in this embodiment may include a wall-penetrating section 350, which is used to pass through the wall so that the end of the air supply duct 300 extends into the target space 400.

[0162] The ratio of the cross-sectional area of ​​the wall-penetrating section 350 to the power of the air conditioner 100 is less than or equal to 57.37 cm2 / kw, of which the cross-sectional area of ​​the wall-penetrating section 350 is less than or equal to 200 cm2.

[0163] Specifically, in this embodiment, the ratio of the cross-sectional area of ​​the wall-penetrating section 350 of the air supply duct 300 to the power of the air conditioner 100 is less than or equal to 57.37 cm² / kW. For example, when the power of the air conditioner 100 in the wall-penetrating section 350 of this embodiment is 1.5 horsepower or higher, the upper limit of the cross-sectional area of ​​the corresponding wall-penetrating section 350 is 200 cm². When the power of the air conditioner 100 is lower, the cross-sectional area of ​​its wall-penetrating section 350 can be smaller. Furthermore, on the one hand, power has a significant limitation on cross-sectional area; the cross-sectional area of ​​the air supply duct 300 is fixed for a given power. On the other hand, it is subject to existing laws and regulations, and the cross-sectional area cannot be infinitely large. In this embodiment, the ratio of the cross-sectional area of ​​the wall-penetrating section 350 of the air supply duct 300 to the power is less than or equal to 57.37 cm² / kW, and the cross-sectional area of ​​the wall-penetrating section 350 is less than or equal to 200 cm², satisfying the size requirements of the wall-penetrating section 350 while further meeting the power requirements of the air conditioner 100.

[0164] As a specific embodiment of the present invention, as shown in Figures 7 and 8, each air supply duct 300 in this embodiment may include a wall-penetrating section 350. The wall-penetrating section 350 is used to pass through the cavity so that the end of the air supply duct 300 extends into the target space 400. The cross-section of the wall-penetrating section 350 is circular, and the diameter of the wall-penetrating section 350 is less than or equal to 160 mm.

[0165] Specifically, in this embodiment, each air supply duct 300 needs to pass through the wall to enter the target space 400. Therefore, each air supply duct 300 in this embodiment may include a wall-penetrating section 350. In this embodiment, the wall-penetrating section 350 may be circular, and its diameter is less than or equal to 160mm. Furthermore, the diameter of the wall-penetrating section 350 is designed to match the power of the air conditioner 100, which is greater than 1.5 horsepower. In this way, the power requirements of the air conditioner 100 are met, while also satisfying the requirement that the wall-penetrating hole cannot be too large.

[0166] Furthermore, most through-wall holes are circular in structure, so the through-wall section 350 in this embodiment is preferably circular.

[0167] Specifically, the cross-sectional shape of the wall-penetrating section 350 in this embodiment can be circular, square, or other shapes. Preferably, the shape of the wall-penetrating section 350 of the air conditioner 100 in this embodiment is circular, and the cross-sectional area of ​​the wall-penetrating section 350 is less than or equal to 200 cm2, that is, the diameter is less than or equal to 160 mm.

[0168] As a specific embodiment of the present invention, the air outlet volume of the air supply duct 300 in this embodiment is 650 m³ / h to 1100 m³ / h. For example, the air outlet volume can be 650 m³ / h, 700 m³ / h, 750 m³ / h, 800 m³ / h, 900 m³ / h, 1000 m³ / h, or 1100 m³ / h, etc.

[0169] Specifically, when the air supply duct 300 of this embodiment is in complete internal circulation, and the wall-penetrating section 350 of the air supply duct 300 is limited to a diameter of 160mm, the air volume output of this embodiment can reach 650m³ / h to 700m³ / h. When the air supply duct 300 of this embodiment not only has internal circulation but also incorporates external fresh air, the air volume output of the air supply duct 300 of this embodiment can reach 1100m³ / h or even higher.

[0170] Specifically, the air volume is related to the diameter of the air supply duct 300 and the power of the centrifugal fan. Of course, the size of the fresh air opening of the equipment will also have a certain impact on the air volume.

[0171] As a specific embodiment of the present invention, as shown in Figures 7-10, the air supply duct 300 of this embodiment may include a pipe body 360 and a first partition 370, wherein the first partition 370 located inside the pipe body 360 extends in a direction parallel to the extension direction of the pipe body 360, dividing the pipe body 360 into an air inlet duct 310 and a return air duct 320.

[0172] More specifically, in this embodiment, the cross-sectional areas of the air inlet duct 310 and the air return duct 320 are the same. This ensures that the air volume of the air inlet and the air return is equivalent.

[0173] As a specific embodiment of the present invention, the air supply duct 300 of this embodiment is provided with a heat insulation layer (not shown in the figure) on its wall. The heat insulation layer can keep the gas inside the air supply duct 300 warm and isolate it from the ambient temperature, reducing the influence of the external environment on the temperature of the transported gas during the transport process.

[0174] As a specific embodiment of the present invention, the air supply duct 300 in this embodiment is provided with a heat insulation layer (not shown in the figure) on its periphery. The heat insulation layer can insulate the outer wall of the air supply duct 300 and isolate it from the external ambient temperature, thereby ensuring that the gas maintains a stable temperature inside the duct.

[0175] As shown in Figure 34, the air supply duct 300 of this embodiment may include a wall-penetrating section 350, a transition section 301 and an air supply section 302 connected in sequence. The transition section 301 may include a first end 3011 near the wall-penetrating section 350 and a second end 3012 near the air supply section 302. The structure of the pipe wall of the transition section 301 at the first end 3011 is the same as the structure of the pipe wall of the wall-penetrating section 350, and the structure of the pipe wall of the transition section 301 at the second end 3012 is the same as the structure of the pipe wall of the air supply section 302.

[0176] Specifically, the air supply duct 300 in this embodiment may include a wall penetration section 350, a transition section 301, and an air supply section 302. A transition section 301 is provided between the wall penetration section 350 and the air supply section 302. When different air supply sections 302 or different wall penetration sections 350 are used according to different situations, only the structure of the transition section 301 needs to be changed, and the structure of other parts of the duct does not need to be changed, thereby improving the versatility of the duct and reducing production costs.

[0177] For example, when the size of the wall penetration section 350 changes, the size of the end of the transition section 301 closest to the wall penetration section 350 can be changed without changing the structure of the air supply section 302, thus reducing production costs.

[0178] As a specific embodiment of the present invention, the cross-sectional structure of the pipe wall of the through-wall section 350 is different from that of the pipe wall of the air supply section 302, and the cross-sectional structure of the pipe wall of the transition section 301 located at the first end 3011 is different from that of the pipe wall located at the second end 3012.

[0179] Specifically, in this embodiment, the cross-sectional structure of the wall of the through-wall section 350 can be circular, while the cross-sectional structure of the wall of the air supply section 302 can be square (as shown in Figure 10) or circular (as shown in Figure 9). When the cross-sectional structure of the wall of the air supply section 302 is square, the cross-sectional structure of the wall of the through-wall section 350 is different from that of the air supply section 302, which makes the cross-sectional structure of the wall of the first end 3011 of the transition section 301 connected to the through-wall section 350 different from that of the wall of the second end 3012. Thus, the transition section 301 is needed between the through-wall section 350 and the air supply section 302.

[0180] More specifically, as shown in Figure 33, the cross-sectional structure of the pipe wall of the through-wall section 350 in this embodiment is circular, the cross-sectional structure of the pipe wall of the air supply section 302 is square, the cross-sectional structure of the pipe wall of the transition section 301 located at the first end 3011 is circular, and the cross-sectional structure of the pipe wall of the transition section 301 located at the second end 3012 is square. The cross-sectional structure of the pipe wall of the transition section 301 gradually transitions from circular to square in the direction from the first end 3011 to the second end 3012.

[0181] Specifically, generally speaking, the gas flow rate is related to the cross-sectional area of ​​the air supply duct 300. However, due to external factors, its structure can vary even with the same cross-sectional area. For example, since the wall penetration hole is preferably circular, the wall penetration section 350 of the air supply duct 300 is preferably circular. Furthermore, since the air supply section 302 is located outside the wall, considering both aesthetics and ease of installation, a square cross-section (as shown in Figure 10) (including rectangles and squares, with a rectangle being preferred) is more suitable. Therefore, the transition section 301 needs to transition from circular to square, allowing for smoother airflow. When the dimensions of the wall penetration section 350 or the structure of the air supply section 302 change, only the dimensions or structure of the transition section 301 need to be modified, thereby increasing versatility and reducing production costs.

[0182] As a specific embodiment of the present invention, as shown in FIG34, the air supply duct 300 of this embodiment may further include a partition to divide the air supply duct 300 into an air inlet duct 310 and a return air duct 320, and the partitions at the wall penetration section 350, the transition section 301 and the air supply section 302 are connected in sequence.

[0183] More specifically, as shown in Figure 33, in this embodiment, there is a preset angle between the plane of the partition at the wall-penetrating section 350 and the plane of the partition at the air supply section 302, so that there is a preset angle between the plane of the partition at the first end 3011 of the transition section 301 and the plane of the partition at the second end 3012; wherein, the preset angle is 0-90°.

[0184] Specifically, in this embodiment, the closed cross-sectional structures of the wall-penetrating section 350 and the air supply section 302 can both be circular. This ensures that the cross-sectional dimensions of the entire wall-penetrating section 350, air supply section 302, and transition section 301 are consistent, and the partition 340 is also in the same plane, i.e., the preset included angle is 0°. Of course, when the cross-sectional structure of the pipe wall of the air supply section 302 is square, and the cross-sectional structure of the pipe wall of the wall-penetrating section 350 is circular, the preset included angle can also be 0 degrees. Of course, due to the structure of the air outlet duct 500, its preset included angle can also be other angles.

[0185] For example, in this embodiment, as shown in Figures 33 and 34, since the plane where the air outlet of the air outlet duct 500 is located is at 45° to the horizontal plane, the partition of its wall-penetrating section 350 is at 45° to the horizontal plane, while the partition at the air supply section 302 is at 90° to the horizontal plane, so the partition of the wall-penetrating section 350 and the partition of the air supply section 302 are at 45°. Furthermore, since the partition at the first end 3011 of the transition section 301 is connected to the partition of the wall-penetrating section 350, and the partition at the second end 3012 of the transition section 301 is connected to the partition of the air supply duct, to avoid gas turbulence caused by abrupt changes in partition position, the partition of the transition section 301 in this embodiment gradually bends from the first end 3011 to the second end 3012.

[0186] As shown in Figure 35, in a specific embodiment of the present invention, the through-wall section 350 may be provided with a plug-in portion 351. When the through-wall section 350 is connected to the transition section 301, the plug-in portion 351 may be inserted into the inner side of the transition section 301. The plug-in portion 351 may be a protruding or extended structure, and its shape and size may match the inner side of the transition section 301. The through-wall section 350 may be connected to the transition section 301 by inserting the plug-in portion 351.

[0187] Specifically, the insertion portion 351 may be provided with an insertion groove 352, which can be used to pass through the partition of the transition section 301. The insertion groove 352 can be a recess on the insertion portion 351, and its shape and size match the partition of the transition section 301. The insertion groove 352 can extend along the length direction of the insertion portion 351 to ensure that the partition can be smoothly inserted and fixed in the insertion groove 352.

[0188] Specifically, the length direction of the insertion slot 352 can be the same as the length direction of the inner partition of the through-wall section 350, and the inner partition of the through-wall section 350 and the insertion slot 352 can be arranged opposite to each other. This ensures that when the through-wall section 350 is connected to the transition section 301, the partition of the transition section 301 is inserted into the insertion slot 352 and abuts against the partition of the through-wall section 350, so that the partition will not be misaligned or have gaps at the connection, thereby allowing the airflow at the connection to be smooth.

[0189] More specifically, the outer diameter of the insertion part 351 can be smaller than the outer diameter of the through-wall section 350, and the outer diameter of the through-wall section 350 can be the same as the outer diameter of the transition section 301. This allows the size of the insertion part 351 to be slightly smaller than the main body of the through-wall section 350 and the transition section 301, enabling the insertion part 351 to be smoothly inserted into the inside of the transition section 301 without causing installation difficulties or loose connections due to an excessively large outer diameter. Having the outer diameter of the through-wall section 350 the same as the outer diameter of the transition section 301 ensures a smooth appearance at the connection point.

[0190] When connecting the through-wall section 350 to the transition section 301, the partition inside the transition section 301 is aligned with the insertion groove 352 of the insertion part 351 on the through-wall section 350. Since the outer diameter of the insertion part 351 is smaller than the outer diameter of the through-wall section 350, and the outer diameter of the through-wall section 350 is the same as the outer diameter of the transition section 301, the insertion part 351 can be smoothly inserted into the inner side of the transition section 301. After the insertion part 351 is fully inserted into the inner side of the transition section 301, the partition of the transition section 301 will enter the insertion groove 352 of the insertion part 351 and tightly abut against the partition inside the through-wall section 350 to ensure the sealing of the connection.

[0191] As shown in Figure 9, in a specific embodiment of the present invention, the air supply section 302 may include a multi-section air supply structure 3021, which is sequentially connected to form the air supply section 302. A retaining ring 390 may be provided at the connection point of the multi-section air supply structure 3021, which engages and seals the ends of the air supply structures 3021 on both sides.

[0192] Specifically, as shown in Figures 36 and 37, in two adjacent air supply structures 3021, one air supply structure 3021 may be provided with a first connecting part 3022, and the other air supply structure 3021 may be provided with a second connecting part 3023. The first connecting part 3022 and the second connecting part 3023 are connected together. The connection method of the first connecting part 3022 and the second connecting part 3023 can be plug-in, snap-fit, or threaded connection, etc. The design of the first connecting part 3022 and the second connecting part 3023 enables the two adjacent air supply structures 3021 to be quickly and firmly connected together, ensuring a smooth airflow transition and the stability of the overall structure.

[0193] More specifically, the first connecting part 3022 can be sleeved around the second connecting part 3023. The second connecting part 3023 has a partition, which can be connected to the partition in the adjacent air supply structure 3021. The inner diameter of the first connecting part 3022 can be slightly larger than the outer diameter of the second connecting part 3023, so that the first connecting part 3022 can be smoothly sleeved around the second connecting part 3023. The second connecting part 3023 can be provided with a connecting groove 3024, and the first connecting part 3022 can be correspondingly provided with a protrusion that can be inserted into the connecting groove 3024. The length direction of the connecting groove 3024 can be consistent with the length direction of the partition in the second connecting part 3023, and the length direction of the protrusion can be consistent with the length direction of the partition in the adjacent air supply structure 3021. This ensures that when the first connecting part 3022 is sleeved around the second connecting part 3023, the partition in the second connecting part 3023 is connected to the partition in the adjacent air supply structure 3021.

[0194] As a specific embodiment of the present invention, the air conditioner of this embodiment may include a filter (not shown in the figure). The filter can be set at the air outlet of the return air duct 320 and the air inlet of the evaporator. The air outlet of the return air duct 320 is the position before the return air flow enters the evaporator. Setting the filter at the air outlet of the return air duct 320 and the air inlet of the evaporator can effectively filter dust, particulate matter and other impurities in the return air, prevent these pollutants from entering the evaporator and affecting the heat exchange efficiency of the evaporator and the normal operation of the air conditioning system.

[0195] The filter can be installed at the air inlet of the return air duct 320. The air inlet of the return air duct 320 is the entrance where the return airflow enters the return air duct 320. Installing the filter here can filter pollutants in the return air as soon as possible.

[0196] Specifically, the filter screen can be installed in the housing, located between the air outlet of the return air duct 320 and the air inlet side of the evaporator. The first surface of the filter screen can face the air inlet side of the evaporator, and the second surface of the filter screen can face the air outlet of the return air duct 320. Before entering the evaporator, the return airflow will pass through the second surface of the filter screen. The second surface is the windward side of the filter screen, which is mainly responsible for intercepting dust in the return airflow. The first surface of the filter screen faces the air inlet side of the evaporator to ensure that the filtered airflow can smoothly enter the evaporator.

[0197] As one embodiment, as shown in Figures 5 and 6, a unit 200 in this embodiment can be equipped with one air supply duct 300. Of course, in other embodiments, a unit 200 can be equipped with multiple air supply ducts 300.

[0198] More specifically, as shown in Figure 6, each air supply duct 300 may include a main pipe 330 and at least one branch pipe 340. One end of each branch pipe 340 is connected to the main pipe 330, and the other end is connected to the corresponding target space 400 to supply air to the target space 400.

[0199] When a unit 200 is equipped with one air supply duct 300, and there are multiple target spaces 400, a main pipe 330 and multiple branch pipes 340 can be used to supply air to different target spaces 400 (as shown in Figure 6). When a unit 200 is equipped with multiple air supply ducts 300, and there are multiple target spaces 400, each air supply duct 300 can include one main pipe 330, and the number of air supply ducts 300 is matched according to the number of target spaces 400 and the number of air supply ducts 300. Each air supply duct 300 can supply air to one of the target spaces 400 (as shown in Figure 5).

[0200] As a specific embodiment of the present invention, as shown in Figures 11 and 12, 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.

[0201] 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.

[0202] 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.

[0203] 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.

[0204] 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.

[0205] Of course, in other embodiments, the air outlet 510 and the air outlet direction can be adaptively adjusted to meet different air outlet requirements.

[0206] Specifically, the main pipe 330 can be connected to the air outlet duct 500 through a branch pipe 340, and the airflow is delivered to the air outlet duct 500 through the main pipe 330 and the branch pipe 340 in sequence.

[0207] Specifically, the main pipe 330 can be connected to the air outlet duct 500 through multiple branch pipes 340, and the multiple branch pipes 340 can be set at intervals along the extension direction of the air outlet duct 500.

[0208] More specifically, the multiple branch pipes 340 may include a first branch pipe 341 and a second branch pipe 342. The first branch pipe 341 may be connected to the end of the outlet duct 500, and the second branch pipe 342 may be connected to the middle of the outlet duct 500. For example, as shown in Figure 38, when the outlet duct 500 is vertically installed in the target space 400, the first branch pipe 341 and the second branch pipe 342 may extend from the main pipe 330 of the supply air duct 300. The first branch pipe 341 is connected to the end of the outlet duct 500, and the second branch pipe 342 is connected to the middle of the outlet duct 500. As shown in Figure 39, multiple branch pipes 340 of multiple supply air ducts 300 may also be connected to the end and the middle of the outlet duct 500 respectively. This design can ensure that the airflow is more evenly distributed within the outlet duct 500, avoiding airflow concentration in a certain area, thereby improving the air supply effect.

[0209] As shown in Figure 19, in a specific embodiment of the present invention, 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, and 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 out of the air outlet duct 500, and the air outlet 510 is a channel for airflow to flow out of the air outlet duct 500. The air outlet surface 502 and the mounting surface 505 are connected to form the overall structure of the air outlet duct 500, ensuring the stability of the air outlet duct 500. 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 of the air outlet duct 500 when viewed from the side, as shown in Figure 19. 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), 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. When the mounting surface 505 is fixed to the target object by a 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, the two 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, as shown in Figure 20, so that the connection between the air outlet duct 500 and the target object is smoother and the gaps during the connection are reduced.

[0210] Specifically, there can be multiple mounting surfaces 505, as shown in Figure 20. These 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 its stability. 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 an auxiliary fixing surface of the air outlet duct 500, connecting to the secondary contact surface of the target object, such as a side wall.

[0211] 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. As shown in Figure 19, 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, and 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 at the top, and the second end of the air outlet surface 502 is connected to the mounting surface 505 fixed on the side wall.

[0212] Specifically, the first mounting surface 5051 and the second mounting surface 5052 can be perpendicular or approximately perpendicular. As shown in Figure 19, 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.

[0213] Specifically, the first mounting surface 5051 and the second mounting surface 5052 can be parallel or approximately parallel. As shown in Figure 21, 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. Alternatively, as shown in Figure 22, when a mounting groove is provided on the top of the target object, the first mounting surface 5051 and the second mounting surface 5052 are respectively connected to the inner two side surfaces of the mounting groove, thereby embedding the air outlet duct into the mounting groove, with only the air outlet surface 502 exposed.

[0214] Specifically, the air outlet housing may have a first transition surface 504, which connects to 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. As shown in Figure 21, 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.

[0215] 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.

[0216] More specifically, the second transition surface can connect the first mounting surface 5051 and the second mounting surface 5052, and is perpendicular to both the first mounting surface 5051 and the second mounting surface 5052. The second transition surface is a transition structure of the air outlet housing, used to connect the first mounting surface 5051 and the second mounting surface 5052. Through the second transition surface, the first mounting surface 5051 and the second mounting surface 5052 can smoothly transition at the end of the air outlet duct 500, forming an integral air outlet housing structure. The second transition surface is perpendicular to the first mounting surface 5051 and the second mounting surface 5052, indicating that the extension direction of the second transition surface forms a 90-degree angle with the extension directions of the first mounting surface 5051 and the second mounting surface 5052. This makes the structure of the air outlet duct 500 at the end more stable, able to withstand greater external forces, and avoids deformation or damage due to structural weakness.

[0217] 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. As shown in Figure 19, this allows the air outlet duct 500 to transition smoothly on the target object, thereby making the air outlet duct 500 look aesthetically pleasing when installed on the target object.

[0218] 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. As shown in Figure 21, when the air outlet duct 500 is embedded in the mounting groove on the side 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, so that the air outlet duct 500 is integrated with the target object and the abruptness is reduced.

[0219] As a specific embodiment of the present invention, among the plurality of mounting surfaces 505, at least one mounting surface 505 can be used to connect with an air supply duct so that the airflow in the air supply duct can flow to the air outlet duct 500.

[0220] As a specific embodiment of this application, as shown in Figures 25 and 26, the housing 210 of this embodiment may include a second partition 260. The second partition 260 divides the housing 210 into a first receiving cavity 211 located above and a second receiving cavity 212 located below. The evaporator 220 and the first fan 250 are located in the first receiving cavity 211, and the condenser 230 is located in the second receiving cavity 212.

[0221] Specifically, in this embodiment, the housing 200 can be provided with a second partition 260, which divides the housing 210 into two receiving cavities. These two cavities are respectively equipped with an evaporator 220 and a condenser 230. In this embodiment, the evaporator 220 is located in the upper first receiving cavity 211, which is connected to the air supply duct 300. This allows gas to exchange heat through the evaporator 220 before flowing out through the air supply duct 300 into the target space 400. The condenser 230, located in the second receiving cavity 212, exchanges heat with the liquid in the evaporator 220, ensuring the evaporator 220 reaches a suitable heat exchange temperature. The second partition 260 also prevents gas from passing through both the space containing the evaporator 220 and the space containing the condenser 230, thus avoiding any impact on the heat exchange effect.

[0222] More specifically, in this embodiment, at least one third through hole (not shown in the figure) is provided at the second partition 260, and the third through hole is located at a position corresponding to the location of the condenser 230. Specifically, since condensate easily forms in the evaporator 220 when exchanging heat with the gas, the condensate will flow down the evaporator 220 and drip below. A drip tray can be provided below the evaporator 220, or the second partition 260 can serve as the drip tray. In this embodiment, the third through hole at the second partition 260 allows the condensate to drip down along the third through hole. Since the third through hole is located above the condenser 230, the condensate directly drips onto the condenser 230, thereby cooling the condenser 230 and improving the overall energy efficiency of the unit.

[0223] In another specific embodiment of this application, the second partition 260 is inclined, and the second partition 260 is inclined toward the side where the condenser 230 is located. Specifically, the second partition 260 in this embodiment can be set at an inclination angle, so that the condensate can flow along the second partition 260 to one side and eventually drip onto the condenser 230, thereby cooling the condenser 230 and improving the overall energy efficiency of the unit.

[0224] As a specific embodiment of this application, the housing 210 of this embodiment may further include a third partition 270 disposed in the first receiving cavity 211. The third partition 270 divides the first receiving cavity 211 into a first sub-cavity 213 and a second sub-cavity 214. An evaporator 220 is disposed in the first sub-cavity 213, and a first fan 250 is disposed in the second sub-cavity 214. An air inlet duct 310 is connected to the second sub-cavity 214, and a return air duct 320 is connected to the first sub-cavity 213. A fourth through hole 271 is provided at the third partition 270 so that the air flowing into the first sub-cavity 213 from the return air duct 320 is heat-exchanged by the evaporator 220 and then flows to the second sub-cavity 214 through the fourth through hole 271. The first fan 250 then blows the gas into the air inlet duct 310.

[0225] Specifically, in this embodiment, the first receiving cavity 211 is divided into a first sub-cavity 213 and a second sub-cavity 214 by a third partition 270. This allows the inlet of the air inlet duct 310 to be connected to the second sub-cavity 214, while the outlet of the return air duct 320 is connected to the first sub-cavity 213. This separates the exhaust gas from the return gas, preventing gas from flowing into the air inlet duct 310 without heat exchange, which would affect the exhaust temperature.

[0226] Furthermore, in this embodiment, a fourth through hole 271 is provided at the third partition 270, and the first fan 250 can be a centrifugal fan. The air inlet of the centrifugal fan is located at the fourth through hole 271, and the air outlet 510 of the centrifugal fan can be directly connected to the inlet of the air inlet duct 310, directly blowing the gas in the first sub-cavity 213 into the air inlet duct 310.

[0227] More specifically, in this embodiment, a fresh air inlet (not shown in the figure) is provided on the side wall of the first receiving cavity 211, and a fresh air valve (not shown in the figure) is provided at the fresh air inlet so that when the fresh air valve is opened, the first fan 250 blows part of the gas flowing from the first sub-cavity 213 into the second sub-cavity 214 and part of the fresh air entering from the fresh air inlet into the air intake duct 310.

[0228] Specifically, in this embodiment, a fresh air inlet is provided on the side wall of the first receiving cavity 211. When the centrifugal fan blows the gas from the first sub-cavity 213 into the air inlet duct 310, due to the negative pressure, outside air will enter the second sub-cavity 214 through the fresh air inlet and then be blown into the air inlet duct 310 by the centrifugal fan.

[0229] Specifically, a fresh air valve is installed at the fresh air inlet. When the temperature difference between indoors and outdoors is small, the fresh air valve can be opened, so that the fresh air and the gas in the first sub-cavity 213 are blown into the air intake duct 310 and then into the target space 400. When the temperature difference between indoors and outdoors is large, the fresh air valve can be closed, and only the gas in the first sub-cavity 213 is blown into the target space 400.

[0230] Specifically, in this embodiment, the fresh air inlet and fresh air valve can be located on the side wall of the first sub-cavity 213 or on the side wall of the second sub-cavity 214. Preferably, the fresh air inlet and fresh air valve are located on the side wall of the first sub-cavity 213, so that the fresh air can pass through the evaporator 220 together with the gas flowing in through the return air duct 320 for heat exchange before being blown into the air inlet duct 310 by the centrifugal fan.

[0231] As a specific embodiment of this application, the second receiving cavity 212 may further include a fourth partition 280, which divides the second receiving cavity 212 into a third sub-cavity 215 and a fourth sub-cavity 216. The evaporator 220 is located in the third sub-cavity 215, and the compressor 240 is located in the fourth sub-cavity 216. The third sub-cavity 215 may further include a second motor (not shown in the figure) and a second fan 290. The second motor drives the second fan 290 to rotate to dissipate heat from the condenser 230. The second motor drives the second fan 290 to rotate, and the second fan 290 carries away the heat from the condenser 230 during rotation, preventing the condenser 230 from becoming too hot.

[0232] As a specific embodiment of this application, at least one side wall of the third sub-cavity 215 is provided with an air outlet 217, and a grille 218 is provided at the air outlet 217. The condenser 230 is arranged around the side wall of the third sub-cavity 215, which does not have an air outlet. Specifically, the grille 218 in this embodiment can, on the one hand, prevent external dust from entering the second receiving cavity 212, and on the other hand, protect the outside world from harming personnel caused by the fan.

[0233] Specifically, the second fan 290 in this embodiment can be an axial flow fan.

[0234] As a specific embodiment of this application, as shown in Figures 25 and 26, the housing 210 of this embodiment may include a second partition 260. The second partition 260 divides the housing 210 into a first receiving cavity 211 located above and a second receiving cavity 212 located below. The evaporator 220 is located in the first receiving cavity 211 and the condenser 230 is located in the second receiving cavity 212.

[0235] Specifically, in this embodiment, the housing 200 can be provided with a second partition 260, which divides the housing 210 into two receiving cavities. These two cavities are respectively equipped with an evaporator 220 and a condenser 230. In this embodiment, the evaporator 220 is located in the upper first receiving cavity 211, which is connected to the air supply duct 300. This allows gas to exchange heat through the evaporator 220 before flowing out through the air supply duct 300 into the target space 400. The condenser 230, located in the second receiving cavity 212, exchanges heat with the liquid in the evaporator 220, ensuring the evaporator 220 reaches a suitable heat exchange temperature. The second partition 260 also prevents gas from passing through both the space containing the evaporator 220 and the space containing the condenser 230, thus avoiding any impact on the heat exchange effect.

[0236] More specifically, in this embodiment, at least one third through hole (not shown in the figure) is provided at the second partition 260, and the third through hole is located at a position corresponding to the location of the condenser 230. Specifically, since condensate easily forms in the evaporator 220 when exchanging heat with the gas, the condensate will flow down the evaporator 220 and drip below. A drip tray can be provided below the evaporator 220, or the second partition 260 can serve as the drip tray. In this embodiment, the third through hole at the second partition 260 allows the condensate to drip down along the third through hole. Since the third through hole is located above the condenser 230, the condensate directly drips onto the condenser 230, thereby cooling the condenser 230 and improving the overall energy efficiency of the unit.

[0237] In another specific embodiment of this application, the second partition 260 is inclined, and the second partition 260 is inclined toward the side where the condenser 230 is located. Specifically, the second partition 260 in this embodiment can be set at an inclination angle, so that the condensate can flow along the second partition 260 to one side and eventually drip onto the condenser 230, thereby cooling the condenser 230 and improving the overall energy efficiency of the unit.

[0238] In another specific embodiment of this application, the third through hole is located on the air outlet side of the evaporator 220. Positioning the third through hole on the air outlet side of the evaporator 220 facilitates rapid and concentrated collection of condensate, allowing the condensate to drip more quickly onto the condenser 230, thus cooling the condenser 230.

[0239] As another specific embodiment of this application, a condensation pipe (not shown in the figure) is provided at the third through hole. One end of the condensation pipe is connected to the third through hole, and the other end of the condensation pipe is set towards the condenser 230. When the evaporator 220 exchanges heat with the gas, the condensate will flow to the condenser 230 through the condensation pipe to cool the condenser 230. By setting the condensation pipe, the design feasibility of the third through hole can be improved, and the effect of guiding the flow of condensate can also be accurately achieved.

[0240] The fuselage 200 includes a first fan 250, which is located within a first receiving cavity 211.

[0241] The air inlet of the first fan 250 is connected to the air outlet of the evaporator 220, and the air outlet of the first fan 250 is connected to the air inlet of the air inlet duct 310. By placing the first fan 250 inside the first receiving cavity 211, the size of the indoor unit can be further reduced effectively. At the same time, since there is only the air supply duct 300 and no evaporator 220 or fan in the indoor unit, the air conditioner 100 is quieter when blowing air in the target space 400, thus improving the user experience.

[0242] As a specific embodiment of this application, the housing 210 of this embodiment may further include a third partition 270 disposed in the first receiving cavity 211. The third partition 270 divides the first receiving cavity 211 into a first sub-cavity 213 and a second sub-cavity 214. An evaporator 220 is disposed in the first sub-cavity 213, and a first fan 250 is disposed in the second sub-cavity 214. An air inlet duct 310 is connected to the second sub-cavity 214, and a return air duct 320 is connected to the first sub-cavity 213. A fourth through hole 271 is provided at the third partition 270 so that the air flowing into the first sub-cavity 213 from the return air duct 320 is heat-exchanged by the evaporator 220 and then flows to the second sub-cavity 214 through the fourth through hole 271. The first fan 250 then blows the gas into the air inlet duct 310.

[0243] Specifically, in this embodiment, the first receiving cavity 211 is divided into a first sub-cavity 213 and a second sub-cavity 214 by a third partition 270. This allows the inlet of the air inlet duct 310 to be connected to the second sub-cavity 214, while the outlet of the return air duct 320 is connected to the first sub-cavity 213. This separates the exhaust gas from the return gas, preventing gas from flowing into the air inlet duct 310 without heat exchange, which would affect the exhaust temperature.

[0244] Furthermore, in this embodiment, a fourth through hole 271 is provided at the third partition 270, and the first fan 250 can be a centrifugal fan. The air inlet of the centrifugal fan is located at the fourth through hole 271, and the air outlet 510 of the centrifugal fan can be directly connected to the inlet of the air inlet duct 310, directly blowing the gas in the first sub-cavity 213 into the air inlet duct 310.

[0245] As a specific embodiment of this application, the third through hole is located on the side of the first fan 250 away from the third partition 270. By setting the third through hole on the side of the first fan 250 away from the third partition 270, when the first fan 250 draws the airflow in the second sub-cavity 214 into the air inlet duct 310, the temperature of this part of the airflow will not be affected by the condenser 230, thus preventing the airflow at the location of the condenser 230 from entering the second sub-cavity 214 through the third through hole and reducing the temperature fluctuation of the airflow blown into the air inlet duct 310.

[0246] As a specific embodiment of this application, a gap is formed between the bottom end of the third partition 270 and the second partition 260, the gap being at least sufficient for the condensate from the evaporator 220 to flow into the second sub-cavity 214. By providing a gap between the bottom end of the third partition 270 and the second partition 260, the condensate from the evaporator 220 can flow into the second sub-cavity 214 to cool the temperature inside the second sub-cavity 214, thereby cooling the first fan 250 and improving the working efficiency of the first fan 250.

[0247] Specifically, the second partition 260 is inclined, and the height of the end of the second partition 260 facing the second sub-cavity 214 is lower than the height of the end of the second partition 260 facing the first sub-cavity 213. This allows the condensate from the evaporator 220 to flow more quickly through the gap into the second sub-cavity 214 through the second partition 260, which has a certain guiding effect on the condensate and accelerates the flow of the condensate.

[0248] More specifically, in this embodiment, a fresh air inlet (not shown in the figure) is provided on the side wall of the first receiving cavity 211, and a fresh air valve (not shown in the figure) is provided at the fresh air inlet so that when the fresh air valve is opened, the first fan 250 blows part of the gas flowing from the first sub-cavity 213 into the second sub-cavity 214 and part of the fresh air entering from the fresh air inlet into the air intake duct 310.

[0249] Specifically, in this embodiment, a fresh air inlet is provided on the side wall of the first receiving cavity 211. When the centrifugal fan blows the gas from the first sub-cavity 213 into the air inlet duct 310, due to the negative pressure, outside air will enter the second sub-cavity 214 through the fresh air inlet and then be blown into the air inlet duct 310 by the centrifugal fan.

[0250] Specifically, a fresh air valve is installed at the fresh air inlet. When the temperature difference between indoors and outdoors is small, the fresh air valve can be opened, so that the fresh air and the gas in the first sub-cavity 213 are blown into the air intake duct 310 and then into the target space 400. When the temperature difference between indoors and outdoors is large, the fresh air valve can be closed, and only the gas in the first sub-cavity 213 is blown into the target space 400.

[0251] Specifically, in this embodiment, the fresh air inlet and fresh air valve can be located on the side wall of the first sub-cavity 213 or on the side wall of the second sub-cavity 214. Preferably, the fresh air inlet and fresh air valve are located on the side wall of the first sub-cavity 213, so that the fresh air can pass through the evaporator 220 together with the gas flowing in through the return air duct 320 for heat exchange before being blown into the air inlet duct 310 by the centrifugal fan.

[0252] In a specific embodiment of this application, the end of the second partition 260 away from the first receiving cavity 211, together with the shell 210, forms a third through hole. This arrangement helps reduce the weight of the second partition 260. Furthermore, the condensate from the evaporator 220 can flow along the side wall of the shell 210 to the condenser 230, thus guiding the flow of condensate.

[0253] As a specific embodiment of this application, the second receiving cavity 212 of this embodiment may further include a fourth partition 280, which divides the second receiving cavity 212 into a third sub-cavity 215 and a fourth sub-cavity 216. The evaporator 220 is located in the third sub-cavity 215, and the compressor 240 is located in the fourth sub-cavity 216.

[0254] The third sub-cavity 215 may also include a motor (not shown in the figure) and a second fan 290. The motor drives the second fan 290 to rotate to dissipate heat from the condenser 230. As the motor drives the second fan 290 to rotate, the second fan 290 carries away the heat from the condenser 230, preventing the condenser 230 from overheating.

[0255] In one specific embodiment of this application, the compressor 240 is located below the evaporator 220, and the compressor 240 is located on the side of the second fan 290 away from the condenser 230. This arrangement allows for efficient use of the space in the second receiving cavity 212, resulting in a compact structure and improved space utilization.

[0256] As a specific embodiment of this application, at least one side wall of the third sub-cavity 215 is provided with an air outlet 217, and a grille 218 is provided at the air outlet 217. The condenser 230 is arranged around the side wall of the third sub-cavity 215, which does not have an air outlet. Specifically, the grille 218 in this embodiment can, on the one hand, prevent external dust from entering the second receiving cavity 212, and on the other hand, protect the outside world from harming personnel caused by the fan.

[0257] Specifically, the second fan 290 in this embodiment can be an axial flow fan.

[0258] In a specific embodiment of this application, the evaporator 220 divides the first sub-cavity 213 into a first part and a second part. The air inlet side of the evaporator 220 faces the first part of the first sub-cavity 213, and the air outlet side of the evaporator 220 faces the second part of the first sub-cavity 213. The second part of the first sub-cavity 213 communicates with the fourth through hole 271 of the third partition 270. Through this arrangement, the evaporator 220 divides the first sub-cavity 213 into a first part and a second part to respectively accommodate the air inlet side and the air outlet side of the evaporator 220. This allows the airflow entering the first part to pass through the evaporator 220 and flow into the second part, avoiding any impact on the outlet air temperature.

[0259] Specifically, the evaporator 220 is inclined, with its first end near the front of the housing 210 and its second end near the rear of the housing 210. This allows for full utilization of the internal space of the first sub-cavity 213, improving space utilization. Furthermore, the inclined arrangement of the evaporator 220 facilitates its secure installation.

[0260] As a specific embodiment of this application, the housing 210 includes a top plate 700; the top plate 700 has a first air vent 701 and a second air vent 702 spaced apart. The first air vent 701 communicates with the second sub-cavity 214, and the air inlet end of the air inlet duct 310 communicates with the air outlet end of the first fan 250 through the first air vent 701. The second air vent 702 communicates with a first part of the first sub-cavity 213, and the air outlet end of the return air duct 320 communicates with the air inlet side of the evaporator 220 through the second air vent 702.

[0261] Specifically, the first air vent 701 and the second air vent 702 are arranged alternately, and are located on both sides of the third partition 270. In this embodiment, by providing the first air vent 701 and the second air vent 702, the top plate 700 can achieve air supply to the air inlet duct 310 and the air return duct 320 through the first air vent 701 and the second air vent 702 respectively, without affecting each other and reducing the impact on the airflow temperature.

[0262] As a specific embodiment of this application, the housing 210 has a front panel 800 facing forward, which encloses the first receiving cavity 211 and the second receiving cavity 212, and the front panel 800 abuts against the second partition 260. By providing the front panel 800, the first receiving cavity 211 and the second receiving cavity 212 can be enclosed, thereby protecting the components of the first receiving cavity 211 and the second receiving cavity 212, preventing external impurities from entering the interior of the first receiving cavity 211 and the second receiving cavity 212, and improving the cleanliness and stability of the interior of the first receiving cavity 211 and the second receiving cavity 212.

[0263] Specifically, the front panel 800 has an air outlet 217, which communicates with the inner side of the housing 210; the front panel 800 is provided with a grille 218, which is located in front of the air outlet 217. In this embodiment, the grille 218 can prevent external dust from entering the second receiving cavity 212, and also protect the outside world from harming personnel caused by the second fan 290.

[0264] As a specific embodiment of this application, the air supply duct 300 is provided with a transition structure 900.

[0265] The adapter structure 900 is provided with a first adapter part 910 and a second adapter part 920. The air inlet end of the air inlet duct 310 is connected to the air outlet side of the evaporator 220 through the first adapter part 910, and the air outlet end of the return air duct 320 is connected to the air inlet side of the evaporator 220 through the second adapter part 920. By setting the adapter structure 900, the air inlet end of the air inlet duct 310 is connected to the air outlet side of the evaporator 220, and the air outlet end of the return air duct 320 is connected to the air inlet side of the evaporator 220, which has high adaptability.

[0266] Specifically, the adapter structure 900 includes a housing 930 and a partition 940 disposed within the housing 930. The partition 940 divides the interior of the housing 930 into a first adapter portion 910 and a second adapter portion 920. By providing the partition 940, the first adapter portion 910 and the second adapter portion 920 are separated, reducing the temperature influence between them and improving the user experience.

[0267] Specifically, the first end of the outer shell 900 is connected to the outer shell 210, and the second end of the outer shell 210 is connected to the air supply duct 300. The cross-sectional area of ​​the first end of the outer shell 900 is larger than the cross-sectional area of ​​the second end of the outer shell 900. In this embodiment, the cross-sectional area of ​​the first end of the outer shell 900 is larger than the cross-sectional area of ​​the second end of the outer shell 900. This has a converging and accelerating effect on the airflow entering the transition structure 900, which helps to allow cold air to quickly enter the target space 400. It also has a diffusion and deceleration effect on the airflow exiting the transition structure 900, allowing the airflow in the target space 400 to undergo rapid heat exchange.

[0268] As a specific embodiment of this application, the air intake volume of the air supply duct 300 in this embodiment is 650 m³ / h to 11000 m³ / h. For example, the air intake volume can be 650 m³ / h, 700 m³ / h, 750 m³ / h, 800 m³ / h, 900 m³ / h, 1000 m³ / h, or 1100 m³ / h, etc.

[0269] Specifically, when the fresh air valve in this embodiment is closed, with complete internal circulation and the wall-penetrating section 350 of the air inlet duct limited to a diameter of 160mm, the air intake volume in this embodiment can reach 650m³ / h to 700m³ / h. When the fresh air valve in this embodiment is open, combining internal circulation with external fresh air, the air intake volume of the air inlet duct in this embodiment can reach 1100m³ / h or even higher. Specifically, the air intake volume is related to both the diameter of the air supply duct 300 and the power of the centrifugal fan. Of course, the size of the fresh air inlet will also have a certain impact on the air intake volume.

[0270] As a specific embodiment of this application, as shown in FIG28, the air outlet duct 500 is provided with a decorative panel 600, which can be used to face the target space 400.

[0271] Installing a decorative panel 600 on the air outlet duct 500 and facing it toward the target space 400 helps to enhance the visual effect of the air outlet duct 500 and make it better integrated into the interior decoration style.

[0272] As a specific embodiment of this application, as shown in FIG29, the air outlet duct 500 is provided with an air outlet surface 502, the air outlet surface 502 forms an air outlet 510, and the decorative panel 600 is disposed on the air outlet surface 502.

[0273] Understandably, the air outlet surface 502 is the area where airflow flows from the inside of the duct to the outside. The air outlet 510 formed on the air outlet surface 502 provides a clear airflow outlet area, allowing airflow to flow out of the duct in an orderly manner to effectively reach the target space 400.

[0274] It should be noted that the position indicated by the dashed line in Figure 29 represents the location of the air outlet 502.

[0275] The decorative panel 600 is installed on the air outlet surface 502, which can cover the entire air outlet surface 502 or a part of it. This not only enhances the aesthetics of the air conditioner, but also protects the air outlet 510, preventing dust and foreign objects from entering.

[0276] For example, the air outlet 510 can be a hole or groove provided on the air outlet surface 502. When the air outlet 510 is hole-shaped, it can be a round hole, an elliptical hole, or a strip-shaped hole, etc.; when the air outlet 510 is groove-shaped, it can be a straight groove or a wavy groove, etc. This application embodiment does not impose any limitations on the specific shape of the air outlet 510.

[0277] It should be noted that different shapes of air outlets 510 can achieve different airflow controls to meet the airflow needs of specific environments. Furthermore, the shape design of the air outlet 510 also directly affects the aesthetic appearance of the air conditioner; diverse hole and slot designs allow the air outlet duct 500 to better integrate into different interior decoration styles.

[0278] As a specific embodiment of this application, as shown in FIG29, the decorative panel 600 and the air outlet 510 are offset.

[0279] Specifically, the decorative panel 600 and the air outlet 510 are not completely aligned, which increases the flexibility and aesthetics of the design without affecting the normal flow of air.

[0280] By setting the air outlet in a staggered manner, the obstruction of airflow can be reduced to avoid interfering with the airflow, while also providing a certain degree of shielding to prevent direct view of the interior of the air outlet 510.

[0281] As another specific embodiment of this application, the decorative panel 600 covers at least a portion of the air outlet 510.

[0282] Specifically, by partially covering the air outlet 510, the appearance of the air outlet duct 500 is improved, while allowing airflow to flow out through the uncovered part, which can play a guiding role.

[0283] As a specific embodiment of this application, as shown in FIG28, the length direction of the decorative panel 600 is parallel to the length direction of the air outlet duct 500.

[0284] Specifically, the long side of the decorative panel 600 is aligned with the long side of the air outlet duct 500, meaning they extend in the same direction.

[0285] By setting the length of the decorative panel 600 parallel to the length of the air outlet duct 500, it is possible to ensure that the decorative panel 600 and the air outlet duct 500 form a unified visual line, making the overall air outlet duct 500 more consistent and smooth. This not only enhances the visual aesthetics of the air conditioner but also helps to simplify the manufacturing and installation process, as the parallel structure makes it easier to achieve standardized and modular production.

[0286] As a specific embodiment of this application, the surface of the decorative panel 600 facing away from the air outlet duct 500 is arranged parallel to the air outlet surface 502, and the surface of the decorative panel 600 facing away from the air outlet duct 500 has a decorative pattern.

[0287] Specifically, the outer surface of the decorative panel 600 (i.e. the side away from the air outlet duct 500) is parallel to the air outlet surface 502.

[0288] This parallel arrangement ensures overall visual consistency between the decorative panel 600 and the air outlet surface 502, making the air conditioner appear neater and more harmonious. At the same time, the parallel design helps optimize the airflow path, reducing airflow interference, turbulence, and resistance, resulting in a smooth airflow.

[0289] By setting decorative patterns on the decorative panel 600, users' needs for aesthetics and personalization can be met, allowing the air conditioner to better integrate into different indoor environments and decoration styles.

[0290] The decorative patterns can be customized according to the user's preferences, and this application embodiment does not impose any restrictions on this.

[0291] As a specific embodiment of this application, as shown in FIG29, the surface of the decorative panel 600 facing the air outlet duct 500 is spaced apart from the air outlet surface 502.

[0292] Specifically, there is a certain gap between the inner surface of the decorative panel 600 (i.e., the side facing the air outlet duct 500) and the air outlet surface 502. This means that the decorative panel 600 is not directly attached to the air outlet surface 502, but maintains a certain distance.

[0293] This spacing creates a buffer zone, allowing airflow between the air outlet 502 and the decorative panel 600, which helps reduce direct obstruction of airflow and optimizes airflow distribution and flow path. Furthermore, the spacing reduces the direct impact of the decorative panel 600 on the air outlet 510, lowering noise and vibration.

[0294] Specifically, by setting a gap between the decorative panel 600 and the air outlet surface 502, a certain degree of installation flexibility is provided for the decorative panel 600. For example, sound-absorbing materials or other functional components can be added to the gap to reduce airflow turbulence and noise that may be caused by direct contact between the decorative panel 600 and the air outlet surface 502.

[0295] As a specific embodiment of this application, as shown in FIG30, a light strip 610 is provided on the surface of the decorative panel 600 facing the air outlet duct 500, and the light strip 610 can at least emit light towards the air outlet surface 502.

[0296] Specifically, by incorporating a light strip 610 on the inner surface of the decorative panel 600, the air conditioner can provide additional lighting effects without affecting its primary function. For example, the light strip 610 can provide soft backlighting, enhancing the ambiance of the indoor environment to improve the product's versatility and user experience, especially in environments requiring soft lighting.

[0297] Specifically, the light from the light strip 610 is at least partially directed toward the air outlet 502, meaning that the light can be emitted through the air outlet 502 or its surrounding area.

[0298] This light direction design allows the light to be evenly distributed around the air outlet surface 502, providing a uniform lighting effect. This not only enhances the visual appeal of the air conditioner but can also be used to indicate the operating status of the air conditioner or as nighttime lighting.

[0299] As a specific embodiment of this application, the extension direction of the light strip 610 is the same as the length direction of the decorative panel 600.

[0300] Specifically, the layout of the light strip 610 is parallel to the long side of the decorative panel 600. This parallel design allows the light strip 610 to visually integrate with the decorative panel 600, ensuring that the light is evenly distributed along the entire length of the decorative panel 600, enhancing the overall aesthetics and harmony. Furthermore, the parallel design simplifies the installation and wiring of the light strip 610, making the product design more concise and efficient.

[0301] As a specific embodiment of this application, the light strip 610 includes a plurality of LED beads, which are arranged sequentially at intervals along the length of the decorative panel 600.

[0302] Understandably, LED beads can form the basic unit for the light emission of the LED strip 610. Multiple LED beads enable more flexible lighting control, such as adjusting brightness and color changes, and also improve the reliability of the LED strip 610. Even if individual LED beads fail, the overall lighting effect will not be significantly affected, providing richer lighting effects and higher reliability.

[0303] Specifically, the LED beads are arranged along the long side of the decorative panel 600, with a certain interval between adjacent beads. By arranging the LED beads at intervals along the length, the light strip 610 can provide uniform light coverage across the entire decorative panel 600. Furthermore, the spacing between the LED beads ensures even light distribution, avoiding light spots or shadows, thus providing a smooth lighting effect. In addition, the spacing of the LED beads also helps with heat dissipation, extending their lifespan.

[0304] As a specific embodiment of this application, there are multiple light strips 610, and the arrangement direction of the multiple light strips 610 is parallel to the width direction of the decorative panel 600.

[0305] The use of multiple light strips 610 can enhance the brightness and coverage of the lighting, making the light more uniform and sufficient. The air conditioner can provide uniform lighting effects over a wider area, while also facilitating the provision of more flexible lighting solutions, such as independent control of different areas or adjustment of different brightness levels, to meet the needs of different environments and users.

[0306] By arranging the light strips 610 parallel to the width of the decorative panel 600, the light can be evenly distributed in the width direction, and the entire surface of the decorative panel 600 can be evenly illuminated, avoiding the light from being concentrated in one direction and ensuring the uniform distribution of light and visual harmony.

[0307] As a specific embodiment of this application, the light strip 610 can be used to emit light of different colors, and the light strip 610 can at least be used to indicate the status of the air conditioner.

[0308] The LED strip 610 has the ability to emit multiple colors of light, providing diverse lighting effects according to different scenarios or user preferences, thus offering a richer visual experience.

[0309] Specifically, the light strip can indicate the air conditioner's operating status through different colors or flashing patterns, such as on, off, cooling, heating, or malfunction. Associating the color changes of the light strip 610 with the air conditioner's status increases the device's operability and user experience. Users can intuitively understand the air conditioner's operation, helping to quickly identify its status and reducing misoperation and troubleshooting time.

[0310] For example, the light strip 610 can be made of LED beads, and the color of the light can be adjusted as needed.

[0311] As a specific embodiment of this application, the decorative panel 600 is configured as an electronic display panel.

[0312] Specifically, the decorative panel 600 is not only a static aesthetic component, but can also be a functional electronic display panel that can display information or images.

[0313] By integrating the decorative panel 600 into an electronic display panel, the air conditioner can provide dynamic information display functions, such as current temperature, humidity, air conditioner operating mode, time, and weather forecast, increasing the air conditioner's interactivity and information transmission capabilities. Users can intuitively understand the status of the air conditioner and environmental information through the display panel, enhancing the convenience of controlling and operating the air conditioner.

[0314] As a specific embodiment of this application, the decorative panel 600 is detachably connected to the air outlet duct 500.

[0315] Specifically, the decorative panel 600 can be connected to the air outlet duct 500 through a certain mechanism, allowing it to be easily disassembled and reinstalled.

[0316] The detachable connection design makes the installation and maintenance of the decorative panel 600 more convenient. Users can easily remove the decorative panel 600 for cleaning, replacement, or repair without the need for professional tools or technical support. Furthermore, the detachable connection allows users to change the decorative panel 600 to different styles according to their needs, enhancing the personalization and adaptability of the air conditioner.

[0317] As a specific embodiment of this application, as shown in Figures 29 and 30, the decorative panel 600 is provided with a first mounting member 620, and the decorative panel 600 can be detachably connected to the air outlet duct 500 through the first mounting member 620.

[0318] Specifically, the first mounting component 620 makes the installation and removal of the decorative panel 600 simpler and more reliable. Users can quickly fix or remove the decorative panel 600 using the first mounting component 620, reducing installation time and complexity.

[0319] For example, the first mounting component 620 may be a structure such as a snap-fit, screw hole, slide rail or magnet, used to fix and remove the decorative panel 600, which helps to make the replacement and maintenance of the decorative panel 600 more efficient and convenient.

[0320] As a specific embodiment of this application, the first mounting component 620 is configured as a magnetic component, and the air outlet duct 500 has a magnetic attraction part, and the magnetic component can attract the magnetic attraction part.

[0321] Specifically, the first mounting component 620 is a magnetic assembly, which can be made of a magnet or magnetic material, for connecting to the air outlet duct 500. The air outlet duct 500 is provided with a magnetic attraction part that interacts with the magnetic component, and the magnetic attraction part can be made of ferrous material or other magnetizable material.

[0322] The magnetic components can effectively attract each other with the magnetic suction part, forming a stable connection. This magnetic connection method does not require additional tools or complicated operations, and users can easily fix or remove the decorative panel 600. This not only ensures the reliability of the connection, but also simplifies the installation and removal process of the decorative panel 600, reducing installation and maintenance time and costs.

[0323] In addition, this mutually attracting connection method reduces the use of mechanical fasteners, making the air conditioner's appearance simpler and enhancing the product's aesthetics.

[0324] As a specific embodiment of this application, the air outlet duct 500 is made of magnetic material, and the magnetic components can attract each other with the air outlet duct 500.

[0325] Specifically, if the air outlet duct 500 is made of magnetic material, the duct itself can act as a magnetic attraction part and interact with the first mounting part 620.

[0326] By selecting magnetic materials as the material for the air outlet duct 500, there is no need to set up additional magnetic suction parts on the air outlet duct 500, which simplifies the structure, reduces the complexity of manufacturing and assembly, and also helps to reduce production costs.

[0327] As a specific embodiment of this application, the air outlet duct 500 is provided with a magnetic structure, the magnetic structure being opposite in direction to the magnetic poles of the magnetic component, and the magnetic component being able to attract the magnetic structure.

[0328] Specifically, a magnetic structure is installed on the air outlet duct 500. This magnetic structure can be made of magnetic material or contain magnetic materials. The presence of the magnetic structure provides a clear adsorption position for the magnetic components of the decorative panel 600, ensuring the stability and reliability of the connection, facilitating precise control of the adsorption position of the magnetic components, and improving the accuracy of the connection.

[0329] The magnetic structure and the magnetic component have opposite magnetic pole directions, which ensure a strong attraction between them, thus providing a stable connection and ensuring that the decorative panel 600 can be firmly fixed to the air outlet duct 500.

[0330] As a specific embodiment of this application, as shown in FIG30, there are multiple first mounting members 620, and at least some of the multiple first mounting members 620 are spaced apart along the length direction of the decorative panel 600.

[0331] By setting multiple first mounting parts 620, the number of connection points can be increased, the connection force can be better distributed, the pressure on individual connection points can be reduced, the connection strength can be improved, and structural deformation caused by thermal expansion and contraction or vibration can be reduced.

[0332] Multiple first mounting pieces 620 are spaced apart along the length direction, which can provide a more stable and uniform connection, ensuring that the decorative panel 600 is firmly fixed along the entire length, effectively preventing the decorative panel 600 from warping or loosening, and ensuring that the decorative panel 600 remains stable during use.

[0333] As a specific embodiment of this application, a plurality of first mounting members 620 are arranged in multiple rows and columns, with the row direction of the first mounting members 620 parallel to the length direction of the decorative panel 600 and the column direction of the first mounting members 620 parallel to the width direction of the decorative panel 600.

[0334] The mounting components are arranged in rows along the length of the decorative panel 600, ensuring a stable connection along the length and preventing warping or loosening of the decorative panel 600 in the length direction. The mounting components are arranged in columns along the width of the decorative panel 600, providing continuous support in the width direction, which can better distribute the connection force along the width direction and improve the fixing effect of the decorative panel 600.

[0335] The arrangement of multiple first mounting components (620 in multiple rows and columns) provides more comprehensive support and fixation. The decorative panel 600 is supported over a wider area, reducing localized stress concentration and contributing to improved fixation and durability.

[0336] As a specific embodiment of this application, as shown in FIG28, the length direction of the decorative panel 600 is parallel to the length direction of the air outlet surface 502.

[0337] Specifically, the length of the decorative panel 600 is parallel to the length of the air outlet surface 502, meaning the decorative panel 600 extends in the same direction as the air outlet surface 502. This parallel arrangement ensures visual and structural consistency between the decorative panel 600 and the air outlet surface 502, providing a harmonious appearance. Furthermore, this design helps simplify the installation process and ensures that the decorative panel 600 effectively covers the required area of ​​the air outlet surface 502.

[0338] As a specific embodiment of this application, as shown in FIG28, the width of the air outlet surface 502 is greater than the width of the decorative panel 600; in the width direction of the decorative panel 600, the decorative panel 600 is located inside the air outlet surface 502.

[0339] Specifically, the width of the air outlet surface 502 is larger than the width of the decorative panel 600, and the decorative panel 600 is located inside the air outlet surface 502. Therefore, the two sides of the air outlet surface 502 in the width direction will not be blocked by the decorative panel 600. The decorative panel 600 will not hinder the airflow from here. On the contrary, it will allow the airflow to be fully distributed and diffused outward along the two sides of the air outlet surface 502 in the width direction, increasing the diffusion range of the airflow, which helps to optimize the airflow management of the air conditioner and improve the cooling or heating efficiency.

[0340] As a specific embodiment of this application, as shown in FIG31, the decorative panel 600 has a movable part 630, which is movable relative to the air outlet surface 502; when the air conditioner is in standby mode, the movable part 630 covers part of the air outlet 510; when the air conditioner is in working mode, the movable part 630 opens part of the air outlet 510.

[0341] The movable part 630 is the movable part of the decorative panel 600. The movable part 630 can move within a certain range relative to the fixed main body of the decorative panel 600, so that the decorative panel 600 as a whole can dynamically adjust its coverage of the air outlet 510, thereby adapting to different working states of the air conditioner.

[0342] It should be noted that the position shown by the dashed line in Figure 31 indicates the location of the air outlet surface 502. After the movable part 630 moves relative to the air outlet surface 502, the overall structure formed by the decorative panel 600 and its movable part 630 can cover the entire air outlet surface 502.

[0343] Specifically, when the air conditioner is in standby mode, based on the fact that the decorative panel 600 has already covered part of the air outlet 510, the movable part 630 of the decorative panel 600 can move relative to the air outlet surface 502 to cover the remaining part of the air outlet 510.

[0344] By completely covering the air outlet 510, on the one hand, dust and foreign objects can be reduced from entering the air conditioner in standby mode, protecting the internal components; on the other hand, it can also provide a clean appearance for the air outlet duct 500, making the appearance of the air outlet duct 500 approximately consistent with the environment of the target space 400, with a concealing effect, thereby reducing the visual impact of the air conditioner when it is not in use.

[0345] When the air conditioner is in operation, the movable part 630 of the decorative panel 600 can move relative to the air outlet surface 502 to open part of the air outlet 510, allowing airflow to pass through and ensuring smooth airflow.

[0346] As a specific embodiment of this application, as shown in FIG32, the decorative panel 600 is rotatably disposed on the air outlet duct 500, and the angle between the decorative panel 600 and the air outlet surface 502 is adjustable.

[0347] It should be noted that the position indicated by the dashed line in Figure 32 represents the location of the air outlet 502.

[0348] Specifically, the decorative panel 600 can be rotatably mounted on the air outlet duct 500 around a certain axis, so that the decorative panel 600 can rotate within a certain range, thereby making the angle between the decorative panel 600 and the air outlet surface 502 adjustable.

[0349] Users can change the tilt angle of the decorative panel 600 to influence the direction and intensity of airflow, thereby controlling the coverage of airflow and helping to improve air quality and temperature uniformity in the room.

[0350] Figure 40 is a structural schematic diagram of the ducted air conditioner provided in an embodiment of this application from one perspective. Figure 41 is a structural schematic diagram of the ducted air conditioner in Figure 40 from another perspective.

[0351] Referring to Figures 40 and 41, this application embodiment provides a ducted air conditioner, which includes a main unit 10, an outdoor air supply duct 20, and an indoor air outlet duct 30. The main unit 10 is installed outdoors. One end of the outdoor air supply duct 20 is connected to the main unit 10, and the other end extends into the room. The indoor air outlet duct 30 is installed indoors and communicates with the outdoor air supply duct 20.

[0352] The main unit 10 draws in outside air, which is then heated within the main unit 10 before being sent into the outdoor air supply duct 20. The air flows along the outdoor air supply duct 20 into the indoor air outlet duct 30, and then flows along the indoor air outlet duct 30 and is blown into the room. Thus, the ducted air conditioner delivers air into the room.

[0353] Compared to wall-mounted air conditioners and traditional ducted air conditioners, all types of air conditioners include an indoor unit, which integrates components such as a fan 15, a compressor 14, and a heat exchanger. The ducted air conditioner provided in this embodiment integrates all functions such as air extraction and heat exchange into an external main unit 10, with only an indoor air outlet duct 30 installed indoors, connected to the main unit 10 via an outdoor air supply duct 20.

[0354] With this configuration, the indoor portion of the ducted air conditioner in this embodiment only includes the indoor air outlet duct 30. The indoor air outlet duct 30 has a simple structure and can be long and slender. It can be installed along the interior wall, for example, extending along a corner. The indoor air outlet duct 30 occupies little space and blends better into the interior space. Furthermore, components that generate significant operating noise are integrated into the outdoor unit 10, leaving only airflow within the indoor air outlet duct 30. Therefore, the ducted air conditioner produces very little noise indoors, even achieving a silent operation, thus enhancing the user experience.

[0355] Referring again to Figures 40 and 41, the ducted air conditioner provided in this embodiment may further include an outdoor return air duct 40. The return air inlet 114 of the outdoor return air duct 40 is connected to the indoor unit, and the air outlet of the outdoor return air duct 40 is connected to the main unit 10. Indoor air can enter the outdoor return air duct 40 through the return air inlet 114, then flow along the outdoor return air duct 40 to the main unit 10, and finally be discharged to the outside environment through the exhaust outlet on the main unit 10.

[0356] With this configuration, the ducted air conditioner can deliver outside air into the room through the outdoor supply air duct 20 and the indoor air outlet duct 30, and simultaneously extract indoor air to the outside environment through the outdoor return air duct 40. When the ducted air conditioner is working, it delivers air into the room through the indoor air outlet duct 30, and at the same time, extracts indoor air to the outside through the outdoor return air duct 40.

[0357] In other words, the ducted air conditioner of this application embodiment can supply air into the room and exhaust indoor air to the outside, thus achieving a fresh air function. This accelerates airflow within the indoor environment, enhances indoor air circulation, and achieves rapid regulation of indoor temperature. Furthermore, by continuously supplying fresh air into the room while simultaneously exhausting existing indoor air, it exchanges indoor air, ensuring indoor air quality, preventing air pollution, and avoiding air conditioning sickness caused by polluted air.

[0358] Especially in summer for cooling or winter for heating, indoor doors and windows are usually kept tightly closed to maintain indoor temperature. The ducted air conditioner in this embodiment provides ventilation, quickly adjusting indoor temperature while offering a comfortable environment for users. It can promptly remove indoor odors, eliminate dust and bacteria floating in the indoor air, and dehumidify to prevent condensation, mold, and rot caused by moisture, creating a fresh and comfortable indoor environment for users.

[0359] Additionally, referring to Figures 40 or 41, in this embodiment, the indoor air outlet duct 30 can extend vertically. Alternatively, the indoor air outlet duct 30 can extend along the height of the room. In this way, the air supply area of ​​the indoor air outlet duct 30 covers most or even all of the room's height, resulting in a large air volume and a wide air supply area, which improves the air supply efficiency and uniformity of the ducted air conditioner.

[0360] Furthermore, the vertically extending indoor air outlet duct 30 extends from the ceiling towards the floor. This allows the air delivery area of ​​the indoor air outlet duct 30 to cover a wider portion of the user's activity area. As a result, users can more quickly experience the temperature regulation effect of the ducted air conditioner, especially when they need a quick cool breeze or desire a warmer temperature; the vertically extending indoor air outlet duct 30 provides a better user experience. Simultaneously, because the temperature felt by the user is closer to the air delivery temperature of the indoor air outlet duct 30, it helps reduce the power consumption of the ducted air conditioner, thus saving energy.

[0361] Furthermore, the vertically extending indoor air outlet duct 30 is easier to install and secure. The bottom and top of the indoor air outlet duct 30 can be supported and secured; for example, the top of the indoor air outlet duct 30 can abut against the ceiling or a support, and the bottom of the indoor air outlet duct 30 can abut against the ground or a support. In addition, the lateral support provided by the wall corners extending vertically within the room ensures that the indoor air outlet duct 30 is stably and securely installed indoors.

[0362] Figure 42 is a schematic diagram of the main unit of the ducted air conditioner provided in the embodiment of this application. Referring to Figure 42, the main unit 10 includes a housing 11, which is the main support structure of the main unit 10. The aforementioned components used to realize the functions of air extraction and heat exchange can all be integrated into the housing 11.

[0363] For example, the housing 11 can be rectangular and can be erected on a pre-installed outdoor mounting bracket. For instance, the length of the housing 11 (X direction shown in the figure) is arranged horizontally along the outdoor wall surface, the width of the housing 11 (Y direction shown in the figure) corresponds to the thickness of the wall, and the height of the housing 11 (Z direction shown in the figure) extends along the height of the outdoor wall surface. In this way, the main unit 10 occupies less outdoor space and has less impact on the building's appearance.

[0364] Figure 43 is an exploded structural diagram of the main unit in Figure 42. Referring to Figure 43, the housing 11 may include a main housing 111 and a front cover 112, with the front cover 112 disposed on the opening of the main housing 111. The front cover 112 and the main housing 111 together form a receiving cavity. An air supply port 113 communicating with the outdoor air supply duct 20 and a return air port 114 communicating with the outdoor return air duct 40 may be disposed on the main housing 111; for example, both the air supply port 113 and the return air port 114 may be disposed on the top wall of the main housing 111. The front cover 112 may include a support plate 1121 and a cover plate 1122, with the cover plate 1122 affixed to the side of the support plate 1121 facing away from the main housing 111. The support plate 1121 mainly serves a supporting function, while the cover plate 1122 can be customized for aesthetic purposes.

[0365] Referring again to Figure 43, the housing 11 contains an evaporator 12, a condenser 13, a compressor 14, and a fan 15. The evaporator 12 and the condenser 13 are connected by a refrigerant circuit, and the compressor 14 is located on the refrigerant circuit, enabling the refrigerant to circulate between the evaporator 12 and the condenser 13.

[0366] Taking the air conditioning cooling process as an example, the gas inside the casing 11 is cooled down after passing through the evaporator 12. The fan 15 draws the cold air into the outdoor air supply duct 20, and then flows into the indoor air supply duct 30 through the outdoor air supply duct 20, finally delivering cold air into the room through the indoor air supply duct to lower the indoor temperature. Under the action of the fan 15, the indoor air then flows back into the casing 11 through the outdoor return air duct 40. This cycle continues.

[0367] Taking the heating process of an air conditioner as an example, the gas inside the casing 11 is heated by the condenser 13. The hot air is drawn into the outdoor air supply duct 20, then flows into the indoor air supply duct 30, and finally, the warm air is delivered into the room through the indoor air supply duct to raise the indoor temperature. Under the action of the fan 15, the indoor air then flows back into the casing 11 through the outdoor return air duct 40. This cycle continues.

[0368] During this process, the low-temperature, liquid refrigerant is compressed by compressor 14 into a high-pressure, liquid refrigerant, which then enters evaporator 12. In evaporator 12, it absorbs heat and transforms into a low-pressure, gaseous refrigerant. The low-pressure, gaseous refrigerant is then compressed again by compressor 14 into a high-pressure, gaseous refrigerant, which enters condenser 13. In condenser 13, it releases heat and transforms into a low-pressure, liquid refrigerant. This cycle continues.

[0369] For example, the fan 15 can be a high static pressure centrifugal fan to reduce the operating noise of the fan 15, reduce the airflow noise in the outdoor supply air duct 20 and the outdoor return air duct 40, and contribute to the noise reduction and quietness of the duct air conditioner.

[0370] Referring again to Figure 43, since the refrigerant releases heat within the condenser 13, this heat is dissipated from the condenser 13 into the casing 11. To address this, a radiator 16 can be installed inside the casing 11, positioned close to the condenser 13, to dissipate heat from the condenser 13 and maintain the interior of the casing 11 at a suitable temperature.

[0371] The radiator 16 can be a cooling fan. An air inlet 115 and an air outlet 116 can be provided on the casing 11. Under the action of the cooling fan, outside air enters through the air inlet 115 on the casing 11, flows through the condenser 13, carries away the heat from the condenser 13, and is then discharged through the air outlet 116 on the casing 11. For example, the axis of the cooling fan can correspond to the thickness direction of the casing 11. The air inlet 115 can be located on the side wall of the main casing 111, and the air outlet 116 can be located on the support plate 1121 of the front cover 112. A grille 11221 can be provided on the cover plate 1122 of the front cover 112 at the air outlet 116 location.

[0372] Figure 44 is a structural schematic diagram of the main unit in Figure 43 after the front cover is removed. Referring to Figure 44, a first partition 117 can be provided inside the casing 11, dividing the casing 11 along the height direction into a first receiving cavity 1111 and a second receiving cavity 1112, with the second receiving cavity 1112 located above the first receiving cavity 1111. The compressor 14, condenser 13, and radiator 16 can be disposed in the first receiving cavity 1111, and the evaporator 12 and fan 15 can be disposed in the second receiving cavity 1112. Thus, in the ducted air conditioner of this embodiment, the components of the outdoor unit of a conventional air conditioner are integrated in the first receiving cavity 1111 of the main unit 10, and the components of the indoor unit of a conventional air conditioner are integrated in the second receiving cavity 1112 of the main unit 10.

[0373] The first receiving cavity 1111 may also be provided with a second partition 118, which divides the first receiving cavity 1111 along its length into a first sub-cavity 1113 and a second sub-cavity 1114. The compressor 14 can be located in the first sub-cavity 1113, and the condenser 13 and radiator 16 can be located in the second sub-cavity 1114. In this way, the compressor 14 is completely isolated from the condenser 13 and radiator 16, and the second sub-cavity 1114 forms a separate heat dissipation space for the condenser 13, which can improve the heat dissipation efficiency and effect of the condenser 13.

[0374] Referring to Figures 43 and 44, for the fan 15 and evaporator 12 located in the second receiving cavity 1112, the air inlet of the fan 15 can face the side where the return air inlet 114 on the casing 11 is located, and the air outlet of the fan 15 can be connected to the air supply outlet 113 on the casing 11. The evaporator 12 can be located between the return air inlet 114 on the casing 11 and the fan 15. Thus, as shown by the dashed arrow in Figure 44, under the negative pressure of the fan 15, indoor air enters the casing 11 through the outdoor return air duct 40 and from the return air inlet 114 on the casing 11. The air entering the casing 11 flows through the evaporator 12 and is then sent into the outdoor air supply duct 20 by the fan 15.

[0375] As shown in Figure 44, in this embodiment, the housing 11 may also be provided with an air guide plate 119 in the second receiving cavity 1112. The air guide plate 119 and the housing 11 (e.g., the top wall of the housing 11) form an air guide channel 1191, which is connected to the return air port 114 on the housing 11. Furthermore, the air guide plate 119 may be provided with multiple air guide holes 1192, all of which are distributed in the area of ​​the evaporator 12 facing away from the fan 15, and the air guide holes 1192 are connected to the space of the evaporator 12 facing away from the fan 15.

[0376] With this configuration, under the guidance of the air duct 1191, all the air entering from the return air inlet 114 of the casing 11 flows into the first receiving cavity 1111 from the side of the evaporator 12 facing away from the fan 15. This ensures that the airflow passes entirely through the evaporator 12 before flowing into the fan 15. This prevents the airflow entering from the return air inlet 114 from bypassing the evaporator 12 and being directly drawn into the fan 15, ensuring complete and thorough heat exchange between the airflow and the evaporator 12, thus improving the temperature regulation rate and effect of the ducted air conditioner. Furthermore, the design of multiple air guide holes 1192 allows the airflow within the air duct 1191 to flow more evenly across the entire surface of the evaporator 12, reducing airflow turbulence and improving the cooling uniformity of the evaporator 12.

[0377] For example, along the direction away from the fan 15, the opening area of ​​the air guide holes 1192 on the air guide plate 119 can gradually increase. This gradual increase in the opening area of ​​the air guide holes 1192 can include increasing the density of the air guide holes 1192 and increasing the opening area of ​​a single air guide hole 1192. This prevents airflow from concentrating and flowing out from the area near the evaporator 12, thus avoiding ineffective utilization of the area of ​​the air guide channel 1191 away from the evaporator 12. Furthermore, it ensures sufficient airflow circulation within the first receiving cavity 1111, and a more uniform airflow distribution allows for more thorough contact between the air and the evaporator 12, improving the heat exchange effect of the evaporator 12.

[0378] Figure 45 is a schematic diagram of the structure of the ducted air conditioner provided in this embodiment of the application after removing the main unit. Referring to Figure 45, when the ducted air conditioner also includes an outdoor return air duct 40, the outdoor return air duct 40 can also be connected to the indoor air outlet duct 30. In this way, the outdoor return air duct 40 can be integrated with the indoor air outlet duct 30 at the indoor return air inlet 114. The indoor structure of the ducted air conditioner is more centralized and simple, which can improve the indoor aesthetics of the ducted air conditioner and facilitate its indoor installation.

[0379] Based on this, this embodiment also optimizes the air supply path and return path of the duct air conditioner for the aforementioned indoor air outlet duct 30 extending vertically, so that the duct air conditioner can achieve the distribution of cold and warm air, thereby improving the performance of the duct air conditioner.

[0380] Specifically, as shown in Figure 45, in this embodiment, the outdoor ductwork of the ducted air conditioner may further include a downward conversion duct 50 and an upward conversion duct 60. The downward conversion duct 50 connects the outdoor supply air duct 20, the outdoor return air duct 40, and the indoor air outlet duct 30, while the upward conversion duct 60 also connects the outdoor supply air duct 20, the outdoor return air duct 40, and the indoor air outlet duct 30. By switching the gas flow path through the downward conversion duct 50 and the upward conversion duct 60, the effect of distributing cold and warm air is achieved.

[0381] The down-conversion duct 50 includes a down main duct 51, a down branch duct 52, and a down second branch duct 53. The first end of the down main duct 51 is connected to the lower end of the indoor air outlet duct 30. The first ends of the down branch duct 52 and the down second branch duct 53 are both connected to the second end of the down main duct 51. The second end of the down branch duct 52 is connected to the outdoor air supply duct 20, and the second end of the down second branch duct 53 is connected to the outdoor return air duct 40.

[0382] The upper conversion duct 60 includes an upper main duct 61, an upper branch duct 62, and an upper second branch duct 63. The first end of the upper main duct 61 is connected to the upper end of the indoor air outlet duct 30. The first ends of the upper branch duct 62 and the upper second branch duct 63 are both connected to the second end of the upper main duct 61. The second end of the upper branch duct 62 is connected to the outdoor air supply duct 20, and the second end of the upper second branch duct 63 is connected to the outdoor return air duct 40.

[0383] As shown by the solid arrows in Figure 45, when the ducted air conditioner is in cooling mode, the lower end of the indoor air outlet duct 30 serves as the air inlet 30a, and the upper end serves as the return air end 30b. The supplied cold air enters the outdoor air outlet duct 20 from the casing 11, and then enters the next branch duct 52. It flows along the next branch duct 52 to the lower main duct 51, and then enters the indoor air outlet duct 30 from the air inlet 30a at the lower end of the indoor air outlet duct 30, flowing upwards within the duct. The return air enters from the return air end 30b at the upper end of the indoor air outlet duct 30, flows along the upper main duct 61 to the upper second branch duct 63, and then flows from the upper second branch duct 63 to the outdoor return air duct 40, finally entering the casing 11.

[0384] In this way, the cold air generated during cooling flows from bottom to top within the indoor air outlet duct 30. Within the indoor air outlet duct 30, the cold airflow velocity is higher in the central area and relatively lower at the edges, resulting in an overall upward and outward parabolic trajectory. Thus, during cooling, the indoor air outlet duct 30 operates in a bottom-in, top-out mode, achieving a canopy-like cooling airflow. Canopy-like cooling airflow means that the cold airflow flows from bottom to top and gradually disperses, with the cold airflow from the indoor air outlet duct 30 primarily concentrated and dispersed in the upper part of the room, preventing direct cold air from blowing onto users.

[0385] As shown by the dashed arrow in Figure 45, when the ducted air conditioner is in heating mode, the upper end of the indoor air outlet duct 30 serves as the air inlet 30a, and the lower end serves as the return air end 30b. The warm airflow enters the outdoor air outlet duct 20 from the casing 11, and then enters the upper branch duct 62. It flows along the upper branch duct 62 to the upper main duct 61, and then enters the indoor air outlet duct 30 from the air inlet 30a at the upper end of the indoor air outlet duct 30, flowing downwards within the duct. The return airflow enters from the return air end 30b at the lower end of the indoor air outlet duct 30, flows along the lower main duct 51 to the lower second branch duct 53, and then flows from the lower second branch duct 53 to the outdoor return air duct 40, finally entering the casing 11.

[0386] In this way, the warm air generated during heating flows from top to bottom within the indoor air outlet duct 30. Within the indoor air outlet duct 30, the warm airflow velocity is higher in the central area and relatively lower at the edges, with the overall airflow following a downward and outward parabolic trajectory. Thus, during heating, the indoor air outlet duct 30 operates in an upward intake and downward return mode, achieving a carpet-like heating and air distribution. This carpet-like heating and air distribution means that the warm airflow flows from top to bottom and gradually disperses, with the outlet area of ​​the warm airflow in the indoor air outlet duct 30 mainly concentrated and dispersed at the lower part of the room, allowing the warm air to be delivered to the user more quickly and directly.

[0387] With this setup, the connection status of the upper conversion duct 60 and the lower conversion duct 50 needs to be switched between cooling and heating modes. To achieve this, a three-way valve or movable baffle can be installed at the intersection of the outdoor supply duct 20, the lower branch duct 52, and the upper branch duct 62. Similarly, a three-way valve or movable baffle can be installed at the intersection of the upper main duct 61, the upper branch duct 62, and the upper second branch duct 63, and at the intersection of the lower main duct 51, the lower branch duct 52, and the lower second branch duct 53. This allows for the switching of the gas flow path via the three-way valve or movable baffle.

[0388] Figure 46 is a schematic diagram of the structure of the indoor air outlet duct in the ducted air conditioner provided in this application embodiment. Referring to Figure 46, the indoor air outlet duct 30 includes a duct shell 100, which is the outer shell of the indoor air outlet duct 30. The duct shell 100 includes a side plate 110 and a front panel 120, which together form an air outlet duct 101. The airflow entering the indoor air outlet duct 30 flows along the air outlet duct 101.

[0389] The side panel 110 can be a solid plate without holes, while the front panel 120 can have holes. The side panel 110 mainly serves a supporting function to ensure that the casing 100 has sufficient structural strength. The front panel 120 also serves a supporting function. At the same time, the front panel 120 is the exposed surface of the indoor air outlet duct 30. The indoor air outlet duct 30 supplies air into the room through the front panel 120, and the front panel 120 is used to improve the appearance of the indoor air outlet duct 30.

[0390] Taking the installation of indoor air outlet duct 30 in an indoor corner as an example, the cross-sectional shape of the duct shell 100 can be a right triangle. The side plates 110 of the duct shell 100 serve as the two right-angled sides of the right triangle, and the two side plates 110 can be respectively attached to the two walls of the corner. The panel 120 of the duct shell 100 serves as the hypotenuse of the right triangle, and the panel 120 faces the indoor space to supply air into the room.

[0391] For example, the cross-section of the casing 100 can be an isosceles right triangle. This ensures that the side plates 110 on both sides of the casing 100 have the same width, and the angles between the panel 120 and the two walls at the corners are the same. The air supply area of ​​the panel 120 expands evenly towards both walls, resulting in a larger overall air supply area and wider air supply range for the indoor air outlet duct 30, leading to better overall temperature regulation of the indoor space. Furthermore, the air supply area of ​​the panel 120 does not tilt towards any one wall, reducing or even eliminating interference from the wall on the airflow, preventing turbulence and eddies, ensuring smooth airflow from the indoor air outlet duct 30, and avoiding airflow loss that could affect its efficiency.

[0392] Referring again to Figure 46, the panel 120 of the casing 100 may include a decorative portion 121 and an air outlet portion. Along the width direction of the panel 120, the decorative portion 121 may be located in the middle area of ​​the panel 120, while the air outlet portions may be located on both sides of the decorative portion 121. The air outlet portion has air outlet holes that penetrate both sides of the panel 120 in the thickness direction. The air outlet holes connect the air outlet duct 101 inside the casing 100 with the indoor space, and the indoor air outlet duct 30 supplies air into the room through the air outlet holes. The decorative portion 121 may be a solid portion without holes, and its main function is decoration.

[0393] Therefore, the panel 120 of the casing 100 not only serves the function of air supply but also enhances the appearance of the indoor air outlet duct 30. By placing the air outlets on both sides of the decorative section 121, the panel 120 achieves better symmetry. Not only is the panel 120 more aesthetically pleasing, but the symmetrical airflow from both sides of the panel 120 also results in a more uniform air supply effect for the indoor air duct.

[0394] It should be noted that the cross-sectional shape of the casing 100 is generally an isosceles right triangle, which can refer to the extension line of the outer surface of the decorative part 121 and the side plate 110 forming a right isosceles triangle. The shape and structure of the air outlet can be flexibly designed according to the requirements of the air supply effect, and this embodiment does not impose specific restrictions on this.

[0395] In some embodiments, the decorative portion 121 of the panel 120 may be provided with a light strip (not shown in the figure), which emits light when powered. In this way, the light strip can serve as indoor lighting, providing an additional function for the indoor air duct 30 and making its functions more diverse. Furthermore, the light strip also serves a decorative function, illuminating the indoor air duct 30 itself and enhancing its aesthetics.

[0396] For example, the light strip can be installed in the same direction as the overall extension of the housing 100. When the housing 100 extends along the wall along the interior height direction, the light strip can also be installed along the interior height direction. In this way, the matching degree between the light strip and the housing 100 is higher, and the lines of the light strip after being lit are smooth and simple, which helps to improve the appearance of the indoor air outlet duct 30.

[0397] Regarding the placement of the light strip, as an example, the light strip can be placed on the front side of the decorative part 121 (the side surface of the decorative part 121 in the thickness direction and facing away from the side panel 110), and the light strip emits light in a forward-facing manner towards the front of the panel 120. For example, the light strip can be located on the front side of the decorative part 121 and near the two side edges in the width direction of the decorative part 121, and the light strip can be, for example, inserted into a light groove opened on the back side of the decorative part 121 (the side surface of the decorative part 121 in the thickness direction and facing towards the side panel 110).

[0398] As another example, the light strip can also be disposed on the two side walls of the decorative section 121 in the width direction, with the light strip emitting light laterally toward both sides of the panel 120. In this case, the light strip can emit light toward the two side walls, for example, illuminating light and shadow or patterns on the two side walls to enhance the lighting atmosphere effect of the light strip. For example, the light strip can be fitted into the light grooves opened in the inner side walls on both sides of the decorative section 121.

[0399] As shown in Figure 46, the entire indoor air outlet duct 30 can be composed of multiple air outlet duct sections 31. Each air outlet duct section 31 is arranged sequentially along the extension direction of the indoor air outlet duct 30, for example, each air outlet duct section 31 is arranged sequentially along the corner of the wall in the indoor height direction. The indoor air outlet duct 30 is formed by sequentially splicing multiple air outlet duct sections 31, and each air outlet duct section 31 can include a side plate 110 and a front panel 120.

[0400] For example, the air outlet duct section 31 can be designed to have a uniform length, such as 1 meter. When installing the indoor air outlet duct 30, the number of air outlet duct sections 31 can be selected according to the indoor wall dimensions (e.g., wall height).

[0401] Furthermore, when the total length of each air outlet duct section 31 after sequential splicing does not match the dimensions of the indoor wall, decorative duct sections 32 can be added to both ends of the spliced ​​air outlet duct section 31. The number and length of the decorative duct sections 32 can be designed based on the difference between the dimensions of the indoor wall and the total length of each air outlet duct section 31, so that the overall length of the indoor air outlet duct 30 matches the dimensions of the wall.

[0402] Additionally, when the decorative pipe section 32 is installed between the air inlet end 30a of the indoor air outlet duct 30 and the air outlet pipe section 31, the decorative pipe section 32 needs to connect the air outlet pipe section 31 to the air inlet end 30a of the indoor air outlet duct 30. In this case, the decorative pipe section 32 can be a hollow pipe section, with both ends connected to the air inlet end 30a of the indoor air outlet duct 30 and the air outlet pipe section 31, respectively, so that the airflow entering from the air inlet end 30a of the indoor air outlet duct 30 can flow into the air outlet pipe section 31 through the decorative pipe section 32.

[0403] Figure 47 is a structural schematic diagram of the air outlet section of the indoor air outlet duct in Figure 46. Figure 48 is a cross-sectional schematic diagram of the air outlet section in Figure 47.

[0404] The air outlet provided on the panel 120 of the casing 100 includes a first air outlet 122, which is located on both sides of the decorative part 121. The first air outlet 122 has first air outlet holes 1221 distributed on it, for example, evenly distributed on the first air outlet 122. As shown by the arrow in FIG48, the airflow flows along the air outlet duct 101 inside the casing 100 and can flow out from the first air outlet holes 1221 opened on both sides of the decorative part 121 to deliver air into the room through the first air outlet 122.

[0405] Furthermore, a first air-softening plate 200 is also provided inside the casing 100. The surface of the first air-softening plate 200 can be perpendicular to the extension direction of the air outlet duct 101, and the first air-softening plates 200 are spaced apart along the extension direction of the air outlet duct 101. Taking the indoor air outlet duct 30 extending along the wall in the indoor height direction as an example, the surface of the first air-softening plate 200 is perpendicular to the indoor height direction and parallel to the indoor plane direction, and the first air-softening plates 200 are spaced apart along the indoor height direction.

[0406] As the airflow flows along the air outlet duct 101, at least part of the airflow will pass through the first air softening plate 200. The first air softening plate 200 is provided with first air softening holes 210. The airflow passing through the first air softening plate 200 flows to the air outlet of the panel 120 after passing through the first air softening holes 210.

[0407] The obstruction effect of the first air softening plate 200 reduces the airflow velocity within the air outlet duct 101, preventing excessive airflow and providing a gentler, more comfortable airflow, thus improving the overall comfort of the indoor air outlet duct 30. Especially in cooling mode, this prevents strong cold air from blowing directly on users, thus avoiding air conditioning sickness. Furthermore, at least a portion of the airflow within the air outlet duct 101 flows forward through the first air softening holes 210 on each of the first air softening plates 200, preventing most or almost all of the airflow from flowing directly to the end of the air outlet duct 101 before being blown out from the air outlet. With the obstruction and guidance effect of each stage of the first air softening plate 200, the airflow can be blown out from the air outlets in various areas along the length of the indoor air outlet duct 30, improving the uniformity of the indoor air outlet duct 30's airflow.

[0408] For example, the first soft air holes 210 can be evenly distributed on the first soft air plate 200. This improves the uniformity of the soft airflow from the first soft air plate 200, thereby improving the uniformity of the airflow from the indoor air outlet duct 30. Furthermore, the pressure within the air outlet duct 101 is more balanced, preventing stress concentration and improving the reliability of the first soft air plate 200 and the duct housing 100. Additionally, it facilitates the design and manufacturing of the first soft air plate 200, making it more versatile.

[0409] For example, the first soft air holes 210 can be arranged in an array on the first soft air plate 200, and the row spacing and column spacing of the first soft air holes 210 can be equal, for example. In this way, the distribution of the first soft air holes 210 is more regular, and the surface of the first soft air plate 200 can be effectively utilized, increasing the density of the first soft air holes 210 and making the airflow in the air outlet duct 101 more dispersed.

[0410] Referring again to Figures 47 and 48, the air outlet on panel 120 may further include a second air outlet 123, which is also located on both sides of decorative section 121. The second air outlet 123 has second air outlet holes 1231 distributed on it, for example, evenly distributed throughout. As shown by the arrows in Figure 48, airflow flows along the air outlet duct 101, or it can flow out from the second air outlet holes 1231 on both sides of the decorative section 121, thus supplying air into the room through the second air outlet 123.

[0411] By providing a first air outlet 122 and a second air outlet 123 on one side of the decorative section 121, an angle is formed between the first air outlet 122 and the second air outlet 123. This can be understood as the first air outlet 122, the second air outlet 123, and the extended line between the decorative section 121 and the side panel 110 forming a triangle, with the total length of the first air outlet 122 and the second air outlet 123 exceeding the length of this extended line. This increases the area of ​​the air outlets on the panel 120, thereby expanding the air outlet area of ​​the indoor air outlet duct 30 and improving its air delivery efficiency and effect.

[0412] The diameter of the first air outlet 1221 on the first air outlet 122 and the diameter of the second air outlet 1231 on the second air outlet 123 can be kept consistent. In this way, when the opening area ratio of the first air outlet 122 is similar to that of the second air outlet 123, the pressure and velocity of the airflow from the first air outlet 122 and the second air outlet are also similar, resulting in uniform airflow throughout the air outlet section, good balance, and high reliability.

[0413] It should be noted that, since the second air outlet 123 is located between the decorative part 121 and the first air outlet 122, the second air outlet 123 is closer to the middle area in the width direction of the panel 120. As mentioned above, the airflow velocity is greater in the central area of ​​the air outlet duct 101 and relatively lower in the edge area. Therefore, the airflow will preferentially (or more) be blown out through the second air outlet 123, affecting the air outlet effect of the first air outlet 122.

[0414] To improve the uniformity of airflow throughout the entire air outlet, in this embodiment, the second air outlet 123 can be located on the side of the decorative part 121 facing the side plate 110. That is, the second air outlet 123 can extend from the decorative part 121 towards the side plate 110. In this way, the end where the first air outlet 122 connects to the second air outlet 123 extends inward into the casing 100. In other words, from the end where the first air outlet 122 connects to the side plate 110 to the end where the first air outlet 122 connects to the second air outlet 123, the first air outlet 122 extends obliquely inward into the casing 100.

[0415] With this configuration, the first air outlet 122 is inclined inward toward the casing 100, and the junction of the first air outlet 122 and the second air outlet 123 is located inside the decorative section 121. This way, the end of the first air outlet 122 that connects to the second air outlet 123 is closer to the center of the air outlet duct 101, which increases the airflow to the first air outlet 122, making the airflow from the first air outlet 122 and the second air outlet 123 more balanced, resulting in better airflow uniformity across the entire air outlet section.

[0416] Furthermore, as shown by the arrow in Figure 48, the first air outlet 122, which is inclined inward towards the casing 100, has its air outlet direction inclined towards the decorative part 121 in the middle of the panel 120. For the first air outlets 122 located on both sides of the decorative part 121, their air outlet directions are both inclined towards the central section. The indoor air outlet duct 30 is typically installed at the corner of the indoor wall. The air outlet direction of the inwardly inclined first air outlet 122 faces away from the wall, which avoids interference from the wall with the airflow of the first air outlet 122, ensuring smooth airflow and preventing turbulence and eddies.

[0417] Furthermore, as shown by the arrow in Figure 48, the air outlet direction of the second air outlet 123 is towards the first air outlet 122, and the airflow from the second air outlet 123 can converge with the airflow from the first air outlet 122. When the two airflows from different directions converge, the mutual friction between the gases can reduce the airflow velocity, slowing down the overall airflow velocity of the air outlet, making the air delivery from the indoor air outlet duct 30 more gentle and comfortable, and enhancing the windless effect of the indoor air outlet duct 30.

[0418] For example, the second air outlet 123 can be perpendicular to the decorative part 121. When the decorative part 121 is subjected to an external force, the force can propagate along the plane of the second air outlet 123. The second air outlet 123 provides good support for the decorative part 121, and the second air outlets 123 located on both sides of the decorative part 121 can support and balance the decorative part 121. Therefore, the decorative part 121 and the second air outlet 123 have higher stress resistance, and the reliability of the indoor air outlet duct 30 is higher.

[0419] Based on this, a second air-softening plate 300 can also be provided inside the casing 100 of the indoor air outlet duct 30. The extension direction of the second air-softening plate 300 can be the same as the extension direction of the decorative part 121, and the second air-softening plate 300 can extend along the extension direction of the casing 100. Taking the indoor air outlet duct 30 extending along the wall in the indoor height direction as an example, the surface of the second air-softening plate 300 is parallel to the indoor height direction.

[0420] As the airflow flows along the air outlet duct 101, at least a portion of the airflow passes through the second air outlet 300 as it flows from the first air deflector 200 to the air outlet on the panel 120. The second air outlet 300 has second air deflector holes 310 distributed on it. The airflow passing through the second air outlet 300 flows through the second air deflector holes 310 and then flows to the air outlet on the panel 120, and is finally delivered outward from the air outlet on the panel 120.

[0421] As shown by the dashed arrow in Figure 48, most of the airflow along the air outlet duct 101 first passes through the first softening plate 200, then flows to the second softening plate 300, and finally is delivered outwards through the air outlet on the panel 120. Thus, the indoor air outlet duct 30 can provide three levels of softened airflow: the first softening plate 200 is equivalent to level one, the second softening plate 300 is equivalent to level two, and the air outlet on the air outlet is equivalent to level three. This enhances the softening effect of the indoor air outlet duct 30, enabling it to achieve an ultra-soft and ultra-comfortable airflow effect.

[0422] For example, the second soft air holes 310 can be evenly distributed on the second soft air plate 300 to improve the uniformity of the soft airflow of the second soft air plate 300, thereby improving the uniformity of the air supply of the indoor air outlet duct 30. Furthermore, the second soft air plate 300 experiences more balanced air pressure, resulting in higher reliability. Additionally, it facilitates the design and manufacturing of the second soft air plate 300, making it more versatile.

[0423] As shown in Figure 48, as an example, the second airflow perforation 310 can perpendicularly penetrate both sides of the second airflow softening plate 300 along its thickness direction. Thus, after passing through the second airflow perforation 310, the airflow flows directly towards the panel 120, and then along a smooth arc path to the air outlets on both sides of the decorative panel. The longer flow path between the second airflow softening plate 300 and the air outlets reduces the airflow velocity, helping to improve the airflow softening effect of the indoor air outlet duct 30. Furthermore, the second airflow softening plate 300 has a simpler and more regular structure, facilitating its processing.

[0424] As another example, the central axis along the length of the second wind deflector 300 can be used as a baseline to design the second wind deflector 300 into zones. The second wind deflector holes 310 located on both sides of the central axis of the second wind deflector 300 are inclined towards the air outlets on both sides of the decorative part 121. Therefore, when airflow passes through the second wind deflector 300, it can guide the airflow to the air outlets on both sides, allowing the airflow to flow more accurately and quickly from the air outlets on both sides into the room.

[0425] In this way, the second air deflector 300 not only softens the airflow but also guides and diverts it, enhancing the orderliness of the airflow within the air outlet duct 101 and increasing the gas velocity within the duct. Consequently, it improves the air delivery efficiency of the indoor air outlet duct 30 and reduces the energy consumption of the ducted air conditioner.

[0426] As for the positions of the first soft air plate 200 and the second soft air plate 300 within the casing 100, the first soft air plate 200 can be connected to the side plate 110 and extend toward the panel 120, while the second soft air plate 300 can be close to the panel 120, so that the airflow in the air outlet duct 101 passes sequentially through the first soft air plate 200, the second soft air plate 300, and the air outlet on the panel 120.

[0427] Furthermore, a gap may exist between the first airflow deflector 200 and the second airflow deflector 300. The airflow guidance of the first airflow deflector 200 differs from that of the second airflow deflector 300, and the gap between them allows the airflow flowing from the first airflow deflector 200 to diffuse to the second airflow deflector 300. Moreover, the airflow forms a certain angle with the second airflow deflector 300 as it flows towards it, allowing the airflow to pass smoothly through the second airflow deflector orifice 310. This avoids the problem of insufficient gap between the first airflow deflector 200 and the second airflow deflector 300, which could potentially affect the smoothness of airflow. It also prevents the airflow exiting from the first airflow deflector orifice 210 from rubbing against the surface of the second airflow deflector 300, thus avoiding noise inside the pipe.

[0428] Furthermore, the gap between the first airflow deflector 200 and the second airflow deflector 300 allows some airflow to bypass the first airflow deflector 200 and pass directly through the second airflow deflector hole 310 on the second airflow deflector 300 before exiting from the air outlet on the panel 120. This increases the gas velocity within the air outlet duct 101 and improves the air delivery efficiency of the indoor air outlet duct 30.

[0429] Referring again to Figures 47 and 48, in this embodiment, the second airflow deflector 300 can be connected between the two second air outlets 123. The air inlet surface of the second airflow deflector 300 does not extend beyond the end of the first air outlet 122 that is connected to the second air outlet 123. That is, the second airflow deflector 300 is located within the space of the second air outlet 123, and the air inlet surface of the second airflow deflector 300 is farther than the air inlet surface of the first air outlet 122.

[0430] With this configuration, the airflow in the central area of ​​the air outlet duct 101 is large and fast. Most of the airflow will pass through the second softening plate 300 and flow to the second air outlet 123, eventually exiting from the second air outlet 123. As mentioned earlier, most of this airflow passes through the first softening plate 200, the second softening plate 300, and the second air outlet 123 in sequence, achieving a three-stage softening effect. This effectively reduces the airflow velocity exiting from the central area of ​​the air outlet duct 101, truly achieving a softening effect.

[0431] The airflow at the edge of the air outlet duct 101 has a relatively small flow rate and low velocity. With the second air outlet 123 installed, a small portion of the airflow will flow into the room through the first air outlet 122 at the edge. By ensuring that this airflow only passes through the first air deflector 200 and the first air outlet 122, a two-stage air deflection is achieved. This avoids excessively restricting the flow rate and velocity of this airflow, ensuring that the first air outlet 122 has an air volume and velocity comparable to the second air outlet 123.

[0432] When the second air softening plate 300 is disposed on the air inlet side of the second air outlet 123, the diameter of the second air softening hole 310 on the second air softening plate 300 can be larger than the diameter of the second air outlet hole 1231 on the second air outlet 123. As the airflow passes through the second air softening plate 300 and the second air outlet 123, the airflow velocity gradually decreases, achieving a gradual softening of the airflow in the indoor air outlet duct 30. Conversely, if the diameter of the second air softening hole 310 is smaller than the diameter of the second air outlet hole 1231, the second air softening plate 300 may restrict the airflow, and in severe cases, may even affect the effective airflow of the second air outlet 123.

[0433] Referring again to Figures 47 and 48, a partition plate 400 may also be provided inside the casing 100 of the indoor air outlet duct 30. The partition plate 400 connects the second air outlet 123 and the corresponding side plate 110. In other words, one end of the partition plate 400 is connected to the side plate 110, and the other end of the partition plate 400 is connected to the second air outlet 123. Ventilation openings 410 are provided on the partition plate 400. The ventilation openings 410 can be arranged sequentially at intervals along the extension direction of the casing 100, and the ventilation openings 410 connect the central area where the first air softener 200 is located with the edge area where the first air outlet 122 is located.

[0434] On one hand, the partition plate 400 connects the second air outlet 123 and the side plate 110, and the two work together to provide complete support between the decorative part 121 and the side plate 110. The partition plate 400, the second air outlet 123, and the second wind deflector 300 form a frame support structure between the decorative part 121 and the side plate 110, which can improve the reliability of the indoor air outlet duct 30 and extend its service life.

[0435] When designing the indoor air duct 30, the side plate 110 of the duct shell 100 and the first air outlet 122 on the panel 120 can be designed as an integral structure, as can the partition plate 400, the second air outlet 123, and the second air softening plate 300. Since the decorative part 121 needs to transmit light emitted from the light strip, it is typically made of a different material than other parts of the duct shell 100 and the first and second air softening plates 200 and 300. Therefore, the decorative part 121 can be a separate component, and an integral connecting plate 124 can be designed between the two second air outlets 123. The connecting plate 124 serves as the mounting base for the decorative part 121, which can be glued or attached to the surface of the connecting plate 124 using screws, bolts, or other fasteners.

[0436] On the other hand, the partition plate 400 divides the pipe shell 100 into multiple vents 410 along its extension direction. The baffle portion 420 between adjacent vents 410 has a diversion function, making it easier for airflow to flow out from the vents 410 on both sides of the baffle portion 420. This reduces the viscosity effect between gases, preventing most of the gas from flowing to the end of the first air outlet 122 and then flowing out, so that a suitable amount of airflow flows out in each region along the length of the first air outlet 122, thereby improving the uniformity of airflow from the first air outlet 122.

[0437] For example, the extending direction of the partition plate 400 can be the same as the extending direction of the second air outlet 123. In other words, the partition plate 400 can extend along the extending direction of the second air outlet 123, and the partition plate 400 can be considered as an extension of the second air outlet 123. In this way, the partition plate 400 and the second air outlet 123 have good integrity and consistency, which can improve the support and reliability of both. For example, the partition plate 400 can also be perpendicular to the decorative part 121.

[0438] As a specific embodiment of the present invention, as shown in Figures 49 to 50, the return air duct 320 is provided with a filter structure 700, which can at least block impurities from the target space 400.

[0439] The filter structure 700 includes a first filter screen 701, which is disposed at the air outlet end of the return air duct 320.

[0440] The first filter 320 is disposed on the housing 210, with the first surface of the first filter 701 facing the air inlet side of the evaporator 220 and the second surface of the first filter 701 facing the air outlet end of the return air duct 320.

[0441] The first surface of the first filter 701 can face the air inlet side of the evaporator, and the second surface of the first filter 701 can face the air outlet end of the return air duct 320. Before entering the evaporator 220, the return airflow passes through the second surface of the first filter 701, which is the windward side of the first filter 701 and is mainly responsible for intercepting dust in the return airflow. The first surface of the first filter 701 faces the air inlet side of the evaporator 220, ensuring that the filtered airflow can smoothly enter the evaporator 220. This effectively filters dust, particulate matter, and other impurities in the return air, preventing these pollutants from entering the evaporator 220 and affecting its heat exchange efficiency and the normal operation of the air conditioning system.

[0442] Specifically, the first filter screen 701 is detachably installed on the outside of the housing 210. The first filter screen 701 can be connected to the housing 210 by bolts or by clips.
