Description

[0001] This application claims priority to Chinese Patent Application No. 202411790493.3, filed on December 6, 2024, entitled "An Air Conditioner", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0003] 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. Utility Model Content

[0004] One objective of the first aspect of this application is to provide an air conditioner that solves the problem of poor noise reduction caused by the indoor unit of an air conditioner typically being located indoors.

[0005] Specifically, this application provides an air conditioner for regulating air within a target space, the air conditioner comprising:

[0006] The unit body is located outside the target space, and the unit body includes a housing and an evaporator, a condenser, a compressor and a first fan disposed within the housing;

[0007] The air supply duct includes an air outlet duct and a return air duct that are isolated from each other. One end of the air supply duct is connected to the body and the other end extends into the target space. The return air duct is connected to the target space.

[0008] An air outlet duct is fixed to the inner wall surface of the target space or at least partially embedded in the inner wall of the target space and extends along the inner wall of the target space. The air outlet duct is connected to the air outlet channel. An air outlet is provided on the air outlet duct, and the plane of the air outlet is exposed outside the inner wall of the target space.

[0009] The air conditioner in this solution can include a main unit, an air supply duct, and an air outlet duct. The main unit can include an evaporator, a condenser, a compressor, and a primary fan; that is, the main unit contains the components of a traditional indoor and outdoor air conditioner. The air supply duct in this solution uses both supply and return air ducts to deliver air from the main unit to the target space, while simultaneously returning air from the target space back to the main unit. By delivering air only through the air supply duct to the target space, the size of the indoor unit can be effectively reduced. Furthermore, since the indoor unit only contains the air supply duct and lacks an evaporator and fan, the air conditioner operates quietly within the target space, improving the user experience.

[0010] Furthermore, by extending the air outlet duct into the target space and fixing or embedding it into the interior wall, the usable indoor space can be reduced, allowing for more flexible room layouts and making it suitable for use in environments with limited space. The embedded or wall-mounted duct design conceals the pipes, reduces exposed components, enhances the overall aesthetics of the interior, and maintains consistency in decorative style. The duct design extending along the interior wall helps distribute airflow more evenly, avoiding direct airflow onto any one area, thereby improving the comfort and efficiency of air conditioning. The embedded structure provides additional sound insulation, reducing the impact of duct vibration and airflow noise on the indoor environment, improving the comfort of the living or working environment. It also reduces exposed pipes and connectors, lowering the risk of tripping or collisions and improving indoor safety.

[0011] Optionally, the air outlet duct includes a sidewall; wherein,

[0012] The sidewalls are located on both sides of the plane where the air outlet is located in the extension direction of the air outlet duct;

[0013] When the air outlet duct is installed on the inner wall surface of the target space, the side wall is fixedly connected to the inner wall of the target space.

[0014] By adding side walls, additional support and fixing points can be provided for the air outlet duct, enhancing its structural stability and preventing swaying or displacement during operation. The side wall design helps conceal the duct connectors and other unsightly parts, improving the overall integration and aesthetics of the interior design. The side walls provide clearly defined fixing points, making installation simpler and faster, and reducing the need for high installation precision.

[0015] Optionally, the target space includes an adjacent first inner wall and a second inner wall, with a first corner formed between the first inner wall and the second inner wall;

[0016] The air outlet duct includes two adjacent sidewalls, and a second corner is formed between the two adjacent sidewalls, the second corner being the same as the first corner;

[0017] The air outlet duct is installed at the first corner, and the two side walls forming the second corner are respectively attached to and connected to the first inner wall and the second inner wall;

[0018] The plane containing the air outlet is located in the area outside the two adjacent side walls.

[0019] By matching the second corner of the air outlet duct with the first corner of the target space (room), corner spaces can be better utilized, avoiding wasted space and resulting in a more compact overall layout. This design integrates seamlessly into the structure of the target space (room), reducing the obtrusiveness of the ductwork and enhancing the overall aesthetics and consistency of the interior design. This design can be adjusted according to the structure of different target spaces (rooms), adapting to various interior wall and corner layouts, thus improving the applicability of the air conditioning system.

[0020] Optionally, the first corner is a right-angle corner, an acute-angle corner, an obtuse-angle corner, or an arc-shaped corner.

[0021] Optionally, the cross-sectional shape of the air outlet duct perpendicular to its extension direction is triangular or quadrilateral.

[0022] It's worth noting that triangular and quadrilateral structures possess excellent geometric stability. Triangles are the most stable basic shape, effectively resisting deformation from external forces, while quadrilaterals (especially rectangles or squares) offer greater internal space while maintaining stability. These two shapes adapt better to various installation environments. Triangular cross-sections fit snugly against corners or ceiling edges, while quadrilateral cross-sections fit closely against flat walls, optimizing space utilization. Triangular and quadrilateral cross-sections integrate better into building structures, reducing jarring elements and enhancing the overall aesthetics and consistency of interior decoration.

[0023] Optionally, it also includes a support, the support comprising a first surface and a second surface that are opposite to each other;

[0024] The first surface is used for fixed connection with the inner wall of the target space;

[0025] The second surface is used for fixed connection with the side wall of the air outlet duct.

[0026] By setting up brackets, additional support points can be provided for the air outlet duct, enhancing its fixation and stability and preventing it from shaking or shifting during operation.

[0027] Optionally, the second side of the bracket is provided with a snap-fit ​​structure;

[0028] An installation structure is provided on the side wall, and the installation structure includes a mating structure that cooperates with the snap-fit ​​structure;

[0029] When the air outlet duct is installed on the second side of the bracket, the snap-fit ​​structure and the mating structure are detachably connected.

[0030] This design simplifies the bracket structure, reduces assembly difficulty, and consequently lowers installation costs. Furthermore, the air outlet duct can be easily disassembled for maintenance, further reducing maintenance costs.

[0031] Optionally, a mounting structure is provided at the side wall, the mounting structure including a magnetic attraction structure;

[0032] When the air outlet duct is installed on the second side of the bracket, the magnetic structure attracts the bracket to each other, so that the air outlet duct can be detachably connected to the second side of the bracket.

[0033] This design simplifies and speeds up the installation and removal of the air duct, eliminating the need for tools or complex operations and saving time and manpower. Since drilling and screws are not required, the magnetic structure minimizes physical damage to the air duct and bracket, maintaining the integrity of the equipment and the wall. The magnetic structure is concealed between the air duct and bracket, preserving the appearance and maintaining a clean and aesthetically pleasing interior.

[0034] Optionally, at least one first baffle perpendicular to the extending direction of the air outlet duct is provided inside the air outlet duct;

[0035] Each of the first baffles is provided with at least one first through hole;

[0038] Optionally, in the direction from the air outlet duct to the air outlet pipe, the distance between two adjacent first baffles gradually increases.

[0039] Optionally, the air outlet of the air duct is provided with:

[0040] The second baffle has at least one second through hole, through which the gas from the air outlet duct passes before being blown out.

[0041] A third baffle is located outside the second baffle, so that gas blown out from the second baffle passes through the third baffle and is then blown out.

[0042] Optionally, the air outlet duct further includes a baffle plate; wherein,

[0043] The wind baffle is located outside the plane of the air outlet, and the wind baffle extends in the same direction as the air outlet duct.

[0044] Air guiding mechanisms are also provided on both sides of the wind deflector's extension direction. These mechanisms are used to guide the gas blown out of the air outlet to both sides of the wind deflector's extension direction.

[0045] Optionally, the air supply duct includes a wall-penetrating section for passing through the cavity so that the end of the air supply duct extends into the target space. The wall-penetrating section has a circular cross-section and a diameter less than or equal to 160 mm.

[0046] Optionally, the air volume of the air supply duct is 650m³. 3 / h~1100m 3 / h.

[0047] Optionally, the air supply duct includes a wall-penetrating section for passing through the cavity so that the end of the air supply duct extends into the target space, and the ratio of the cross-sectional area of ​​the wall-penetrating section to the power of the air conditioner is less than or equal to 57.37 cm². 2 / kw, wherein the cross-sectional area of ​​the wall-penetrating section is less than or equal to 200cm². 2 .

[0048] Optionally, the number of air supply ducts is at least one; wherein each air supply duct includes a main pipe and at least one branch pipe, one end of each branch pipe is connected to the main pipe and the other end extends into one of the target spaces, and each branch pipe includes the wall penetration section.

[0049] Optionally, each of the aforementioned supervisors and the supervisors themselves includes:

[0050] tube body; and

[0051] A first partition located inside the pipe extends in a direction parallel to the direction in which the pipe extends, dividing the pipe into the outlet air duct and the return air duct.

[0052] Optionally, the housing includes a second partition that divides the housing into an upper first receiving cavity and a lower second receiving cavity, wherein the evaporator and the first fan are located in the first receiving cavity, and the condenser is located in the second receiving cavity.

[0053] Optionally, at least one third through hole is provided at the second partition, and the third through hole is located at a position corresponding to the location of the condenser;

[0054] The second partition is inclined, and the second partition is inclined toward the side where the condenser is located.

[0055] Optionally, the housing further includes a third partition disposed within the first receiving cavity, the third partition dividing the first receiving cavity into a first sub-cavity and a second sub-cavity, the evaporator disposed within the first sub-cavity, the first fan disposed within the second sub-cavity, the outlet air duct communicating with the second sub-cavity, the return air duct communicating with the first sub-cavity, and a fourth through hole provided at the third partition so that air flowing into the first sub-cavity from the return air duct passes through the evaporator for heat exchange and then flows through the fourth through hole to the second sub-cavity, and then the first fan blows the gas into the outlet air duct.

[0056] Optionally, a fresh air inlet is provided on the side wall of the first receiving cavity, and a fresh air valve is provided at the fresh air inlet, so that when the fresh air valve is opened, the first fan blows part of the gas flowing from the first sub-cavity into the second sub-cavity and part of the fresh air entering from the fresh air inlet into the air outlet duct.

[0057] The second receiving cavity also includes a fourth partition, which divides the second receiving cavity into a third sub-cavity and a fourth sub-cavity. The evaporator is located in the third sub-cavity, and the compressor is located in the fourth sub-cavity.

[0058] The third sub-cavity also includes a motor and a second fan, the motor driving the second fan to rotate to dissipate heat from the condenser;

[0059] An air outlet is provided on at least one side wall of the third sub-cavity, and a grille is provided at the air outlet;

[0060] The condenser is arranged around the sidewall of the third sub-cavity, which is not an outlet.

[0061] The air conditioner in this solution can include a main unit and an air duct. The main unit can include an evaporator, condenser, compressor, and a primary fan; that is, the main unit contains the components of a traditional indoor and outdoor air conditioner. The air duct in this solution uses supply and return air ducts to deliver air from the main unit to the target space and simultaneously return air from the target space back to the main unit. By delivering air only through the air duct to the target space, the size of the indoor unit can be effectively reduced. Furthermore, since the indoor unit only contains the air duct and lacks an evaporator and fan, the air conditioner operates quietly within the target space, improving the user experience.

[0062] Each air supply duct in this solution may include a wall penetration section, which can be circular with a diameter less than or equal to 160mm, and the diameter of the wall penetration section is suitable for air conditioners with a power greater than 1.5 horsepower. This satisfies both the power requirements of the air conditioner and the requirement that the wall penetration hole not be too large.

[0063] This solution incorporates a first baffle, a second baffle, and a third baffle at the air outlet duct. These three components achieve three levels of uniform airflow, resulting in well-uniform airflow from the air outlet duct with virtually no wind sensation, thus enhancing the user experience.

[0112] 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.

[0113] As a specific embodiment of this application, such as Figures 1 to 4As shown, this embodiment discloses an air conditioner 100, which may include a body 200 and at least one air supply duct 300. The body 200 may include a housing 210 and an evaporator 220, a condenser 230, a compressor 240, and a first fan 250 disposed within the housing 210. One end of each air supply duct 300 is connected to the body 200, and the other end extends to a target space 400. An air outlet duct 310 and a return air duct 320 are disposed within the air supply duct 300, which are arranged side by side. Gas that has undergone heat exchange by the compressor 240 is blown into the air outlet duct 310 by the first fan 250 and then flows into the target space 400. Gas in the target space 400 enters the housing 210 through the return air duct 320.

[0114] 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, a compressor 240, and a first fan 250. That is, the body 200 includes the components of the indoor and outdoor units of a conventional air conditioner 100. The air supply duct 300 in this embodiment achieves the purpose of transporting the gas inside the body 200 to the target space 400 through the supply air duct and the return air duct 320, while simultaneously returning the gas in 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, compressor 240 and fan of the traditional indoor and outdoor units in the same machine, and delivers gas to the target space 400 only through the air supply duct 300. This can effectively reduce the size of the indoor unit. At the same time, since there is only the air supply duct 300 and no other machines such as the evaporator 220 and fan in the indoor unit, the air conditioner 100 is quieter when blowing air in the target space 400, thus improving the user experience.

[0115] 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.

[0116] As one example, such as Figure 5 and Figure 6 As shown, in this embodiment, a body 200 can be equipped with one air supply duct 300. Of course, in other embodiments, a body 200 can be equipped with multiple air supply ducts 300.

[0117] More specifically, such as Figure 6 As shown in the diagram, 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.

[0118] 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 (e.g., Figure 6 (As shown). When a unit 200 is paired with multiple air supply ducts 300, and there are many target spaces 400, each air supply duct 300 can include a main pipe 330, and 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 (e.g., ...). Figure 5 (As shown).

[0119] As a specific embodiment of this application, such as Figure 7 and Figure 8 As shown, 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 160mm.

[0120] 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.

[0121] Furthermore, most through-wall holes are circular in structure, so the through-wall section 350 in this embodiment is preferably circular.

[0122] As another specific embodiment of this application, the air supply duct 300 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. 2 / kw, where the cross-sectional area of ​​the wall-penetrating section 350 is less than or equal to 200cm². 2 .

[0123] 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. 2 / 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 200cm². 2 When the power of the air conditioner 100 is smaller, the cross-sectional area of ​​its wall-penetrating section 350 can be smaller. Specifically, the ratio of the cross-sectional area of ​​the wall-penetrating section 350 of the air supply duct 300 to the power is designed in this embodiment because, on the one hand, power has a significant limitation on the cross-sectional area, and the cross-sectional area of ​​the air supply duct 300 is fixed for a certain power; on the other hand, it is subject to the limitations of existing laws and regulations, and the cross-sectional area cannot be infinitely large.

[0124] 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. 2 That is, the diameter is less than or equal to 160mm.

[0125] As a specific embodiment of this application, such as Figures 7-10 As shown, each main pipe 330 and branch pipe 340 in 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 outlet air duct 310 and a return air duct 320.

[0126] More specifically, in this embodiment, the cross-sectional areas of the outlet air duct 310 and the return air duct 320 are the same. This ensures that the air volume of the inlet and return air is equivalent.

[0127] When the air supply duct 300 includes a main pipe 330 and a branch pipe 340, the air outlet duct 310 of the main pipe 330 and the air outlet 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.

[0128] 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.

[0129] 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 (e.g., Figure 9 (as shown) or other shapes. For example, the pipe between the through-wall section 350 and the fuselage 200 can be designed as square, such as rectangular (as shown). Figure 10 (As shown) 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 in the wall penetration section 350.

[0130] 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.

[0131] As a specific embodiment of this application, such as Figure 9 and Figure 10 As shown, the air supply duct 300 in this embodiment is formed by one or more duct units 380. When the air supply duct 300 is formed by connecting multiple duct units 380 together, the multiple duct units 380 are interlocked to form the entire duct. Specifically, a retaining ring 390 is provided at the connection position between the duct units 380 (e.g., Figure 9 As shown), the retaining ring 390 snaps the ends of the pipe units 380 on both sides together and seals them.

[0132] As a specific embodiment of this application, such as Figure 11 and Figure 12 As shown, each air supply duct 300 in this embodiment is provided with an air outlet duct 500 at its end, which is connected to the air outlet duct 310. The extension direction of the air outlet duct 500 is parallel to the air outlet direction of the air outlet duct 310. An air outlet 510 is provided at the air outlet duct 500. The gas in the air outlet duct 310 flows into the air outlet duct 500 and is blown out from the air outlet 510.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] Of course, in other embodiments, the air outlet 510 and the air outlet direction can be adaptively adjusted to meet different air outlet requirements.

[0138] 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.

[0139] As a specific embodiment of this application, such as Figure 13-16 As shown, in this embodiment, the air outlet duct 500 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] Specifically, at least a portion of the outer periphery of each first baffle 520 contacts the inner wall of the air outlet duct 500.

[0145] 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.

[0146] Specifically, the 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.

[0147] Preferably, all the first baffles 520 in this embodiment are arranged in parallel to each other.

[0148] 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.

[0149] As a specific embodiment of this application, the ratio of the cross-section of the first through hole 521 to the total cross-sectional area of ​​the first baffle 520 is positively correlated with the distance from the first baffle 520 to the air outlet duct 310.

[0150] For example, in this embodiment, 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 outlet duct 310 to the position away from the air outlet duct 310.

[0151] Specifically, since the wind speed is higher near the air outlet duct 310 and lower far from the air outlet 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 outlet duct 310 and far from the air outlet duct 310, resulting in good uniformity of the blown gas and improving the user experience.

[0152] Specifically, the cross-sectional area of ​​the first through hole 521 of the first baffle 520 in this embodiment can be changed by altering the number of first through holes 521, or by changing the cross-sectional area of ​​each first through hole 521.

[0153] As a specific embodiment of this application, the density of the first baffle 520 gradually decreases in the direction from the position near the air outlet duct 310 to the position away from the air outlet duct 310. That is, the distance between two adjacent first baffles 520 gradually increases in the direction from the air outlet duct 310 to the air outlet pipe 500.

[0154] Specifically, in this embodiment, the density of the first baffles 520 near the air outlet duct 310 is set to be large, while the density of the first baffles 520 far from the air outlet duct 310 is set to be small. This makes the airflow near the air outlet duct 310 and the airflow far from the air outlet duct 310 have similar speeds, thereby making the uniformity of the gas blown out of the air outlet 510 good.

[0155] 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.

[0156] More specifically, the diameter of the first through hole 521 at the first baffle 520 in this embodiment is adjustable. In this way, 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.

[0157] In another embodiment, the first baffle 520 of this embodiment can be set with different areas at different distances from the air outlet duct 310, so as to further increase the uniformity of the air outlet.

[0158] As a specific embodiment of this application, such as Figure 13-16 As shown, in this embodiment, a second baffle 530 is provided at the air outlet 510 of the air outlet duct 500. The second baffle 530 is provided with at least one second through hole 531, through which the gas from the air outlet duct 500 is blown out.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] Specifically, the third baffle 540 in this embodiment can be designed as a filter structure (e.g. Figure 11 and 12 As shown), the filter structure of this embodiment can be obtained by setting a filter screen in the center of the frame structure. As another specific embodiment, the third baffle 540 of this embodiment can be designed as a horizontal strip-shaped grid structure (e.g., Figure 13 and Figure 14 As shown), the direction of airflow can be adjusted by changing the number and direction of the grid lines. As another specific embodiment, the third baffle 540 of this embodiment can also be designed as a perforated partition structure (e.g., Figure 15 and Figure 16As shown in the figure, the size and distribution of the holes on the partition can be designed according to the actual situation. 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, which makes the air blown out from the air outlet duct 500 more uniform and almost windless, thus improving the user experience.

[0163] As a specific embodiment of this application, such as Figure 17 and Figure 18 As shown, in this embodiment, the air outlet duct 500 is also provided with a baffle plate 550 and air guiding mechanisms 560 located on both sides of the baffle plate 550 at the air outlet 510. The air guiding mechanism 560 guides the gas blown out of the air outlet 510 to the side away from the baffle plate 550.

[0164] 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.

[0165] Specifically, in this embodiment, the air guide mechanism 560 can be rotatably connected to the wall of the air outlet duct 500, thereby controlling the direction of the gas blown out from the air guide mechanism 560 by controlling the rotation of the air guide mechanism 560.

[0166] Specifically, the air guiding mechanism 560 in this embodiment may include multiple parallel air guiding blades, each of which can rotate. The multiple air guiding blades can rotate individually or in conjunction with each other.

[0167] As a specific embodiment of this application, such as Figure 11 As shown, the air outlet duct 500 of this embodiment may include multiple interconnected and communicating air outlet modules 501. Adjacent air outlet modules 501 are snap-fitted together. Each air outlet module 501 may have 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.

[0168] Specifically, the target object in this embodiment can be a specific object in the target space 400, such as the front wall of a room or a cabinet. The following description uses the inner wall 600 of the target space as an example.

[0169] As one embodiment, the air outlet duct 500 can be fixed to the surface of the inner wall 600 of the target space or at least partially embedded in the inner wall 600 of the target space and extend along the inner wall 600 of the target space. The air outlet duct 500 is connected to the air outlet channel 310. An air outlet 510 is provided on the air outlet duct 500, and the plane 511 where the air outlet is located is exposed on the inner wall 600 of the target space.

[0170] In this embodiment, when the air outlet duct 500 is embedded in the inner wall 600 of the target space, only the plane 511 where the air outlet of the air outlet duct 500 is located can be exposed (e.g., Figure 19 , Figure 21 and Figure 22 As shown in the figure, this reduces the space occupied by the air duct by 500, making the room layout more flexible and suitable for use in environments with limited space.

[0171] The 500mm recessed or wall-mounted air duct design conceals pipes, reduces exposed components, enhances the overall aesthetics of the interior, and maintains consistency with the decorating style. Extending along the inner wall, the 500mm air duct design helps distribute airflow more evenly, avoiding direct airflow onto any one area, thus improving air conditioning comfort and efficiency. The recessed structure provides additional sound insulation, reducing the impact of air duct vibration and airflow noise on the indoor environment, enhancing the comfort of the living or working environment. It also reduces exposed pipes and connections, lowering the risk of tripping or collisions and improving indoor safety.

[0172] Specifically, in this embodiment, the plane 511 where the air outlet of the air outlet duct 500 is located can form a substantially continuous plane or curved surface with the inner wall 600 of the target space located outside the air outlet 510.

[0173] As a specific embodiment of this application, such as Figure 19 As shown in Figure 20, the air outlet duct 500 of this embodiment may also include a side wall 570, wherein the side wall 570 may be located on both sides of the plane 511 where the air outlet is located in the extension direction of the air outlet duct 500, that is, the side wall 570 is located on both sides of the height direction of the plane 511 where the air outlet is located.

[0174] When the air outlet duct 500 is installed on the surface of the inner wall 600 of the target space, the side wall 570 is fixedly connected to the inner wall 600 of the target space. And the plane 511 where the air outlet of the air outlet duct 500 is located is exposed outside the target space 400.

[0175] By providing sidewall 570, additional support and fixing points can be provided for the air outlet duct 500, enhancing its structural stability and preventing it from shaking or shifting during operation. The design of sidewall 570 helps to conceal the connectors and other unsightly parts of the air outlet duct 500, improving the integration and aesthetics of the interior design. Sidewall 570 provides clearly defined fixing points, making the installation process simpler and faster, and reducing the need for high installation precision.

[0176] For example, see Figure 19A As shown, the target space 400 may include adjacent first inner walls 601 and second inner walls 602, with a first corner 603 formed between the first inner walls 601 and second inner walls 602. The air outlet duct 500 may include two adjacent side walls 570, with a second corner 571 formed between the two adjacent side walls 570. The second corner 571 is the same as the first corner 603 (same angle). The air outlet duct 500 may be installed at the first corner 603, and the two side walls 570 forming the second corner 571 are respectively fitted and connected to the first inner wall 601 and the second inner wall 602. The plane 511 where the air outlet is located is located outside the area of ​​the two adjacent side walls 570. For example, the plane 511 where the air outlet is located and the two adjacent side walls 570 form the outer periphery of the air outlet duct 500.

[0177] By matching the second corner 571 of the air outlet duct 500 with the first corner 603 of the target space 400 (room), the corner space of the room can be better utilized, avoiding wasted space and making the overall layout more compact. This design can be well integrated into the structure of the target space 400 (room), reducing the obtrusiveness of the duct and improving the overall aesthetics and consistency of the interior decoration. This design can be adjusted according to the structure of different target spaces (rooms), adapting to various interior wall and corner layouts, thus improving the applicability of the air conditioner.

[0178] In one possible implementation, the first corner 603 and the second corner 571 have the same shape. The first corner 603 can be a right-angle corner, an acute-angle corner, an obtuse-angle corner, or an arc-shaped corner. In the embodiments of this application, the form of the first corner 603 is not further limited.

[0179] Optionally, the cross-sectional shape of the air outlet duct 500 perpendicular to its extension direction is triangular or quadrilateral. For example, it can be a right triangle, acute triangle, obtuse triangle, rectangle, square, or rhombus, etc. In this embodiment, the cross-sectional shape of the air outlet duct 500 perpendicular to its extension direction is not further limited.

[0180] It's worth noting that triangular and quadrilateral structures possess excellent geometric stability. Triangles are the most stable basic shape, effectively resisting deformation from external forces, while quadrilaterals (especially rectangles or squares) offer greater internal space while maintaining stability. These two shapes adapt better to various installation environments. Triangular cross-sections fit snugly against corners or ceiling edges, while quadrilateral cross-sections fit closely against flat walls, optimizing space utilization. Triangular and quadrilateral cross-sections integrate better into building structures, reducing jarring elements and enhancing the overall aesthetics and consistency of interior decoration.

[0181] For example, when the cross-section of the air outlet duct 500 is a right triangle (such as...) Figure 19 As shown), the target object can be the interior wall of the room, which can be located between the top and side wall 570 of the room, with only the air outlet 510 exposed. The plane 511 where the air outlet is located forms a continuous zigzag plane with the surface of the top and side wall.

[0182] When the cross-section of the 500mm exhaust duct is quadrilateral, such as Figure 20 Two of the sides can be installed on the top and side wall 570 of the target object, while the other two sides can have an air outlet 510 set in one place or both places.

[0183] Preferably, when the cross-section of the air outlet duct 500 is quadrilateral, such as... Figure 21 and Figure 22 As shown, the plane 511 where the air outlet is located and the exposed surfaces of the target object around the air outlet 510 form a basically continuous plane or curved surface.

[0184] More preferably, such as Figure 22 As shown, in this embodiment, the plane 511 where the air outlet is located is on the same plane as the exposed surface of the target object near the air outlet 510.

[0185] In one possible implementation, such as Figure 23 and Figure 24 As shown, the air conditioner may also include a bracket 580, which may include a first side and a second side facing away from each other. The first side is used for fixed connection to the inner wall 600 of the target space. The second side is used for fixed connection to the side wall 570 of the air outlet duct 500.

[0186] By setting bracket 580, additional support points can be provided for air outlet duct 500, enhancing the fixation and stability of air outlet duct 500 and preventing it from shaking or shifting during operation.

[0187] As a specific embodiment of this application, such as Figure 23 and Figure 24As shown, the second side of the bracket 580 is provided with a snap-fit ​​structure 581. In this embodiment, the side wall 570 of the air outlet duct 500 is provided with an installation structure (not shown in the figure), which may include a mating structure that cooperates with the snap-fit ​​structure 581. When the air outlet duct 500 is installed on the second side of the bracket 580, the snap-fit ​​structure 581 and the mating structure are detachably connected.

[0188] This design simplifies the structure of bracket 580, reduces assembly difficulty, and consequently lowers installation costs. Furthermore, the air outlet duct 500 can be easily disassembled for maintenance, further reducing maintenance costs.

[0189] In some other embodiments, the mounting structure may include a magnetic attraction structure. When the air outlet duct 500 is mounted on the second side of the bracket 580, the magnetic attraction structure attracts the bracket 580, so that the air outlet duct 500 is detachably connected to the second side of the bracket 580. Specifically, one bracket 580 may mount one air outlet module 501 or multiple air outlet modules 501.

[0190] This design simplifies and speeds up the installation and removal of the exhaust duct 500, eliminating the need for tools or complex operations and saving time and manpower. Since drilling and screws are not required, the magnetic structure minimizes physical damage to the exhaust duct 500 and bracket 580, maintaining the integrity of the equipment and the wall. The magnetic structure is concealed between the exhaust duct 500 and bracket 580, preserving the appearance and maintaining a clean and aesthetically pleasing interior design.

[0191] Specifically, such as Figure 24 As shown, in this embodiment, a bracket 580 is provided with a snap-fit ​​structure 581, and a corresponding structure is provided on the side wall 570 of the air outlet duct 500 to engage with the snap-fit ​​structure 581. When installing the air outlet duct 500, the bracket 580 can be first fixed to the target object, and then the air outlet duct can be snapped into the snap-fit ​​structure 581 of the bracket 580. In this embodiment, the bracket 580 can simultaneously install two air outlet modules 501.

[0192] Of course, as other embodiments, the mounting structure 580 can be in other forms such as snap-fit, which cooperates with the mounting structure 580 on the target object, so that the air outlet duct 500 can be installed on the target object quickly and flexibly.

[0193] 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.

[0194] As a specific embodiment of this application, such as Figure 25 and Figure 26 As shown, the housing 210 of this embodiment may include a second partition 260, which 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.

[0195] 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.

[0196] 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.

[0197] 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.

[0198] 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, a first fan 250 is disposed in the second sub-cavity 214, an air outlet 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 through 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 outlet duct 310.

[0199] 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 exhaust air 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 exhaust air duct 310 without heat exchange, which would affect the exhaust temperature.

[0200] 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 outlet duct 310, directly blowing the gas in the first sub-cavity 213 into the air outlet duct 310.

[0201] 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 outlet duct 310.

[0202] 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 outlet 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 outlet duct 310 by the centrifugal fan.

[0203] 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 outlet duct 310 and then into the target space. When the temperature difference between indoors and outdoors is large, the fresh air valve can be closed so that only the gas in the first sub-cavity 213 is blown into the target space.

[0204] 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 outlet air duct 310 by the centrifugal fan.

[0205] 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.
