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 household appliance technology, and in particular to an air outlet duct and an air conditioner. Background Technology

[0003] Traditional household wall-mounted air conditioners are divided into indoor and outdoor units. However, regardless of the type of model, because the indoor unit contains core components such as heat exchangers, motors, and fan blades, its external dimensions cannot be designed to be exquisite and compact, thus making it difficult to blend well with the home decoration environment.

[0004] Currently, there are technologies that place the unit outside the wall and use only the air supply duct to deliver the gas into the target space. However, since the air supply duct needs to be integrated with the home decoration environment, the installation of existing air supply ducts is quite difficult. Utility Model Content

[0005] In view of the above problems, this application provides an air outlet duct and an air conditioner, which makes the installation of the air outlet duct more convenient by setting the air outlet duct as multiple air outlet modules and connecting the air outlet modules through a connecting module.

[0006] In a first aspect, embodiments of this application provide an air outlet duct for use in an air conditioner. The air outlet duct includes multiple air outlet modules and a connecting module. The multiple air outlet modules are arranged sequentially along the extension direction of the air outlet duct. Adjacent air outlet modules are connected through the connecting module. The air outlet duct includes an air inlet and an air outlet. The air inlet is located in one of the air outlet modules. Each air outlet module has a partial structure of the air outlet. The inner side of the connecting module is hollow so that the inner cavities of adjacent air outlet modules are connected.

[0007] The air outlet duct of this application is formed by connecting multiple air outlet modules through connecting modules. This allows for adjustment of the duct's dimensions and selection of the appropriate number of air outlet modules based on the actual needs of the target space. On one hand, this facilitates the integration of the air conditioner's outlet duct with the home décor, enhancing the overall aesthetics and thus improving user satisfaction. On the other hand, the modular design of the outlet duct makes installation and disassembly more convenient.

[0008] Furthermore, each air outlet module features a partial structure with an air outlet, allowing airflow to be evenly distributed across multiple points. This avoids the problem of excessively strong or weak localized airflow that can occur with traditional single air outlets. This design contributes to a more uniform and comfortable indoor airflow distribution, thereby enhancing the user experience.

[0009] In some embodiments, each of the two adjacent air outlet modules has a connecting portion at its end facing each other. The connecting portion is a hollow ring, and the connecting portions of the two adjacent air outlet modules are nested within the connecting module. This structural design of the connecting portions of the air outlet modules improves the reliability of the connection between the two adjacent air outlet modules, thereby enhancing the structural reliability of the air outlet duct.

[0010] According to some embodiments of this application, the connecting portion of two adjacent air outlet modules is sleeved on the outside of the connecting module. This facilitates concealing the connecting module within the air outlet duct, improving the aesthetics of the air outlet duct.

[0011] According to some embodiments of this application, along the extension direction of the air outlet duct, the length of the connecting portion is half the length of the connecting module. Thus, when connecting two adjacent air outlet modules, the connecting module and the two connecting portions have the same connection length, resulting in a uniform load distribution on the formed air outlet duct and improving the structural reliability of the air outlet duct.

[0012] According to some embodiments of this application, the connecting part is interference-fitted with the connecting module. This facilitates the formation of a stable connection structure, preventing the connection from loosening due to vibration or airflow pressure in the air outlet duct, and further improving the structural reliability of the air outlet duct.

[0013] According to some embodiments of this application, the inner wall of the air outlet module is provided with a limiting structure. When the connecting module is inserted into the connecting part, the limiting structure and the connecting module abut against each other along the extension direction of the air outlet duct. The limiting structure helps to avoid connection deviations or misalignments of the air outlet module caused by improper installation or over-installation, thereby extending the service life of the air outlet duct.

[0014] According to some embodiments of this application, the connecting module includes at least one of a plastic component and a metal component. This helps control equipment costs and improve the economic efficiency of the product.

[0015] According to some embodiments of this application, the air outlet duct further includes a sealing layer for sealing the gap between the connecting portion and the connecting module. Thus, by providing a sealing layer, the sealing effect of the air outlet duct is improved, preventing air leakage from the connection point of the two air outlet modules and enhancing the structural reliability of the air outlet duct.

[0016] According to some embodiments of this application, the sealing layer includes a sealant. On the one hand, the sealant can be applied by smearing or injection, which is convenient and helps improve production efficiency. On the other hand, using a sealant for sealing also helps save equipment costs.

[0017] According to some embodiments of this application, at least one first baffle is provided inside the air outlet duct. The first baffle is perpendicular to the extension direction of the air outlet duct, and each first baffle is provided with a first through hole. By providing the first baffle, airflow flows through the first through hole, making the air volume distribution inside the air outlet duct uniform.

[0018] According to some embodiments of this application, there are multiple first baffles, and the multiple first baffles are arranged at intervals along the extension direction of the air outlet duct;

[0019] The ratio of the total area of ​​the first through holes on the first baffle to the area of ​​the corresponding first baffle gradually increases in the direction away from the air inlet. Since the wind speed is higher near the air inlet and lower away from the air inlet, this design, by gradually increasing the ventilation area of ​​the first through holes in the direction away from the air inlet, ensures that the air speed is similar near and far from the air inlet, resulting in good uniformity of the blown air and improving the user experience.

[0020] According to some embodiments of this application, the density of the first baffle gradually decreases along the extension direction of the air outlet duct and away from the air inlet. Thus, by adjusting the distribution density of the first baffle, the uniformity of airflow distribution within the air outlet duct is further improved, thereby enhancing the user experience.

[0021] According to some embodiments of this application, a second baffle is provided at the air outlet, and the second baffle has a second through hole. The gas from the air outlet duct passes through the second through hole before being blown out. In this way, the uniformity of gas distribution from the air outlet duct is improved by passing through the second through hole.

[0022] According to some embodiments of this application, a third baffle is further provided at the air outlet. The third baffle is located outside the second baffle, and the air blown out from the second baffle passes through the third baffle before being blown out. In this way, the air discharged from the air outlet duct undergoes three stages of uniform airflow—the first baffle, the second baffle, and the third baffle—resulting in good uniformity of the air discharged from the air outlet duct, reducing the impact on the user, making the airflow felt by the user softer, and improving the user experience.

[0023] According to some embodiments of this application, the air outlet duct includes an air outlet surface, and the air outlet is formed on the air outlet surface. When the air outlet duct is installed at the target object, the air outlet is exposed, and the air outlet surface forms a continuous surface with the side wall surface of the target object located on at least one side of the air outlet. In this way, the air outlet surface and the side wall surface of the target object form a continuous plane, which can reduce energy loss and turbulence caused by airflow impacting the side wall, and also achieve seamless connection between the air outlet and the installation environment. This improves airflow uniformity and cooling / heating effects while achieving an invisible integration of the air conditioning equipment with the home environment.

[0024] Secondly, this application also provides an air conditioner, comprising: a body; the aforementioned air outlet duct, the air outlet duct including an air outlet surface, the air outlet formed on the air outlet surface, the air outlet duct being exposed when installed at a target object, and the air outlet surface forming a continuous surface with the side wall surface of the target object located on at least one side of the air outlet; and a supply air duct, the supply air duct being connected to the air inlets of the body and the air outlet duct respectively, the gas being heat-exchanged through the body, flowing into the air outlet duct through the supply air duct, and being discharged to the target space through the air outlet.

[0025] The air conditioner of this application uses the aforementioned air outlet duct, which is formed by connecting multiple air outlet modules through connecting modules. This allows for adjustment of the duct's dimensions and selection of the appropriate number of air outlet modules based on the actual needs of the target space. On one hand, this facilitates the integration of the air conditioner's outlet duct with the home décor, enhancing the overall aesthetics and increasing user satisfaction. Furthermore, the air outlet surface forms a continuous plane with the sidewall of the target object, reducing energy loss and turbulence caused by airflow impacting the sidewall, and achieving seamless integration between the air outlet and the installation environment. This improves airflow uniformity and cooling / heating efficiency while achieving an invisible integration of the air conditioning equipment with the home environment.

[0026] In some embodiments, the unit body is located outside the target space, while the air outlet duct is located inside the target space. Thus, by placing the air conditioner unit outside the target space and the air outlet duct inside, synergistic optimization of air conditioning operation and user experience is achieved. The external unit body effectively isolates noise sources such as the compressor and fan, significantly reducing indoor noise pollution. Simultaneously, the external space can be utilized to improve air conditioning heat dissipation, increasing cooling / heating efficiency and extending the lifespan of core components. The internal air outlet duct reduces temperature drop or rise losses during airflow, thereby improving temperature control accuracy and response speed. Attached Figure Description

[0052] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0053] Traditional household wall-mounted air conditioners are divided into indoor and outdoor units. However, regardless of the type of model, because the indoor unit contains core components such as heat exchangers, motors, and fan blades, its external dimensions cannot be designed to be exquisite and compact, thus making it difficult to blend well with the home decoration environment.

[0054] Currently, there are technologies that place the unit outside the wall and use only the air outlet duct to deliver the gas into the target space. However, because the air outlet duct needs to be integrated with the home decoration environment, the installation of existing air outlet ducts is quite difficult.

[0055] In view of this, this application provides an air outlet duct and an air conditioner, which makes the installation of the air outlet duct more convenient by setting the air outlet duct as multiple air outlet modules and connecting the air outlet modules through a connecting module.

[0056] refer to Figures 1 to 8 In a first aspect, embodiments of this application provide an air outlet duct 100 for use with an air conditioner 200. The air outlet duct 100 may include a plurality of air outlet modules 110 and a connection module 120.

[0057] Multiple air outlet modules 110 are arranged sequentially along the extension direction of the air outlet duct 100, and adjacent air outlet modules 110 are connected by a connecting module 120. For example, the connecting module 120 can be a connector with mounting holes and positioning holes. The mounting holes on two adjacent air outlet modules 110 are aligned with the positioning holes and located on both sides of the positioning holes. A fastener passes through the two mounting holes to fix the two air outlet modules 110 together. Alternatively, the connecting module 120 can be a sleeve, with both ends fixedly connected to the opposite ends of the two connecting modules 120. The connection method can be socketing, insertion, snap-fitting, or threaded connection, etc.

[0058] Understandably, to better integrate with the home décor environment, the air duct 100 located in the target space (indoors) can have a surface adapted to the ceiling and side walls of the target space. The rear wall of the air outlet module 110 of the air duct 100 can be installed on the side wall of the target space using fasteners such as screws or brackets. The top wall of the air outlet module 110 can be flush with the ceiling to improve the aesthetics of the air duct 100 installation. Furthermore, to enhance integration with the home décor environment, the air outlet 112 of the air duct 100 can be located on a surface facing the target space. This surface can be an inclined surface, meaning the cross-section of the air duct 100 along its length can be triangular. Alternatively, the surface where the air outlet 112 is located can also be arc-shaped, which also improves the aesthetics of the air duct 100. In this case, the cross-section along the length of the air duct 100 can be fan-shaped. Of course, in other embodiments, the surface where the air outlet 112 of the air duct 100 is located can also be other shapes, which designers can adjust according to their needs. This embodiment does not impose any limitations on this.

[0059] When installing in the target space, an appropriate number of air outlet modules 110 can be selected based on the dimensions of the space. This adapts to different installation environments and modularizes the air outlet duct 100, reducing installation difficulty. When the air outlet duct 100 is damaged and needs replacement, only the corresponding air outlet module 110 needs to be replaced, reducing the user's maintenance costs.

[0060] The air outlet duct 100 includes an air inlet 111 and an air outlet 112. The air inlet 111 is located in one of the air outlet modules 110, and each air outlet module 110 has a partial structure of the air outlet 112. In other words, when the air outlet duct 100 is assembled into a whole structure, the air inlet 111 that supplies air into the air outlet duct 100 can be located in one of the air outlet modules 110 (such as one of the air outlet modules 110 located at both ends of the length of the air outlet duct 100). Each air outlet module 110 has an air outlet structure (i.e., the partial structure of the aforementioned air outlet 112) that discharges air into the target space. Thus, when air is supplied to the target space through the air outlet duct 100, the air enters from the air inlet 111 at one end of the air outlet duct 100, and as it passes through each air outlet module 110, a portion of the air can be discharged from each air outlet module 110, providing multiple air outlet positions and avoiding the problem of excessively strong or weak local airflow that may be caused by a traditional single air outlet 112. This design helps to achieve a more uniform and comfortable indoor airflow distribution, thereby improving user satisfaction.

[0061] The inner side of the connecting module 120 is hollow so that the inner cavities of two adjacent air outlet modules 110 are connected. Thus, when two air outlet modules 110 are connected through the connecting module 120, the connecting module 120 forms a flow channel, avoiding obstruction of airflow and improving the reliability of air delivery from the air outlet duct 100.

[0062] The air outlet duct 100 of this application is formed by connecting multiple air outlet modules 110 through a connecting module 120. This allows the specific dimensions of the air outlet duct 100 to be adjusted according to the actual needs of the target space, selecting the appropriate number of air outlet modules 110 and connecting them through the connecting module 120. On the one hand, this facilitates the integration of the air outlet duct 100 of the air conditioner 200 with the home décor environment, improving the overall aesthetics and thus increasing user satisfaction. On the other hand, the modular design of the air outlet duct 100 makes its installation and disassembly more convenient.

[0063] Furthermore, each air outlet module 110 has a partial structure with an air outlet 112, allowing airflow to be evenly distributed at multiple points, avoiding the problem of excessively strong or weak local airflow that may occur with a traditional single air outlet 112. This design helps to achieve a more uniform and comfortable indoor airflow distribution, thereby improving the user experience.

[0064] refer to Figure 2 , Figure 3 and Figure 4In some embodiments, each of any two adjacent air outlet modules 110 has a connecting portion 113 at one end facing each other. The connecting portion 113 is hollow and annular, and is arranged adjacent to the air outlet 112. The connecting portions 113 of two adjacent air outlet modules 110 are nested within the connecting module 120. For example, the connecting portion 113 may be located inside the air outlet module 110, and both ends of the connecting module 120 along its length may be nested within the two connecting portions 113. Alternatively, the connecting portion 113 may be located outside the air outlet module 110, and the two connecting portions 113 may be nested within the two ends of the connecting module 120. Alternatively, one connecting portion 113 may be located inside the air outlet module 110, and the other outside the air outlet module 110, with the two connecting portions 113 extending relative to each other, and the connecting module 120 nested between the two connecting portions 113, forming a multi-layer support structure. Thus, by designing the structure of the connection part 113 of the air outlet module 110, it is beneficial to improve the reliability of the connection between two adjacent air outlet modules 110, thereby improving the structural reliability of the air outlet duct 100.

[0065] refer to Figure 3 and Figure 4 According to some embodiments of this application, the connecting portion 113 of two adjacent air outlet modules 110 is sleeved on the outside of the connecting module 120, forming a more stable connection between adjacent air outlet modules 110 to resist the pressure generated by airflow and the vibration of the air outlet duct 100 during daily use, ensuring the overall stability and durability of the air outlet duct 100. Furthermore, this arrangement is equivalent to housing the structure that mates with the connecting module 120 and the air outlet module 110 within the air outlet duct 100. From an external perspective, the connecting module 120 is not visible, making the appearance of the air outlet duct 100 simpler and improving its aesthetics.

[0066] It should be noted that, in this embodiment, the area of ​​the inner hollow region of the connecting module 120 needs to be no less than the ventilation area of ​​the air duct of the air outlet module 110, so as to avoid affecting the gas flow of the air outlet duct 100.

[0067] According to some embodiments of this application, along the extension direction of the air outlet duct 100, the length of the connecting portion 113 is half the length of the connecting module 120. Thus, on the one hand, when connecting two adjacent air outlet modules 110, the connecting module 120 and the two connecting portions 113 have the same connection length, resulting in a uniform load distribution on the formed air outlet duct 100 and improving the structural reliability of the air outlet duct 100. On the other hand, when connecting two adjacent air outlet modules 110, the connecting module 120 is inserted into each of the two connecting portions 113 by half its length, making the assembly and disassembly process of the air outlet modules 110 simpler and faster. Users can easily fit the connecting portion 113 onto the connecting module 120 without complicated alignment or adjustment steps, improving installation efficiency.

[0068] According to some embodiments of this application, the connecting part 113 and the connecting module 120 are interference-fitted. In other words, the internal space dimension of the connecting part 113 is slightly smaller than the outer wall dimension of the connecting module 120. During installation, the connecting module 120 needs to be forcibly pressed into the connecting part 113 to form a tight contact. This helps to form a stable connection structure, preventing the connection of the air outlet duct 100 from loosening due to vibration or airflow pressure, and further improving the structural reliability of the air outlet duct 100. Furthermore, the interference fit also forms a good seal between the connecting part 113 and the connecting module 120, reducing airflow leakage. This helps to improve the cooling / heating efficiency and performance of the air conditioning system 200, avoiding energy efficiency reduction and uneven indoor temperature distribution caused by airflow leakage.

[0069] According to some embodiments of this application, the inner wall of the air outlet module 110 is provided with a limiting structure. When the connecting module 120 is inserted into the connecting part 113, the limiting structure and the connecting module 120 abut against each other along the extension direction of the air outlet duct 100. For example, the limiting structure can be a limiting protrusion protruding from the inner wall of the air duct of the air outlet module 110. There can be multiple limiting protrusions, which can be arranged circumferentially within the air duct. When the connecting module 120 is installed in place, the connecting module 120 abuts against the limiting protrusion to prevent over-installation or misalignment of the connecting module 120. It should be noted that all multiple limiting protrusions are located within one interface. Alternatively, the limiting structure can also be a boss extending circumferentially along the air duct. When the connecting module 120 is installed in place, the side of the boss facing the connecting module 120 abuts against and limits the connection module 120.

[0070] The limiting structure helps to accurately control the installation position of the connection module 120, avoiding connection deviation or misalignment of the air outlet module 110 caused by improper or over-installation, thereby extending the service life of the air outlet duct 100.

[0071] According to some embodiments of this application, the connecting module 120 includes at least one of plastic and metal components. Exemplarily, the connecting module 120 can be made of plastic material. Plastic materials are generally lightweight, which helps reduce the weight of the entire air outlet duct 100, facilitating installation and transportation. The manufacturing cost of plastic materials is generally low, which also helps reduce the overall cost of the air outlet duct 100, improving cost-effectiveness. Furthermore, some plastic materials have good corrosion resistance, resisting the erosion of materials by harsh environments such as humidity and acids / alkalis, which helps extend the service life of the air outlet duct 100. Alternatively, the connecting module 120 can also be made of metal material. Metal materials have high strength and rigidity, capable of withstanding large mechanical stress and pressure, ensuring the structural stability and durability of the air outlet duct 100. At the same time, metal materials are not prone to aging, maintaining stable performance during long-term use, reducing the frequency of maintenance and replacement of the air outlet duct 100. Alternatively, the connecting module 120 can also use plastic components as the main structure to reduce cost and weight; while using metal components (such as metal support strips within the plastic components) in key areas to enhance strength and stability.

[0072] According to some embodiments of this application, the air outlet duct 100 may further include a sealing layer for sealing the gap between the connecting portion 113 and the connecting module 120. Exemplarily, the sealing layer may be rubber, silicone, or foam plastic, etc., disposed between the connecting portion 113 and the connecting module 120. Thus, by providing a sealing layer, the sealing effect of the air outlet duct 100 is improved, preventing air leakage from the connection point of the two air outlet modules 110, and improving the structural reliability of the air outlet duct 100. Furthermore, the sealing layer can also reduce the noise generated when airflow passes through the connecting portion 113, enhancing the sound insulation effect of the entire air conditioning system 200, thereby improving the user experience.

[0073] According to some embodiments of this application, the sealing layer may include a sealant. On the one hand, sealant can be applied by smearing or injection, which is convenient and helps improve production efficiency. On the other hand, using sealant for sealing also helps save equipment costs.

[0074] Furthermore, the sealant can adapt to connection gaps of different shapes and sizes, ensuring the integrity and reliability of the seal. It can also fill tiny gaps caused by manufacturing tolerances or installation errors, improving the tightness of the connection between the two air outlet modules 110.

[0075] refer to Figure 2 and Figure 3 According to some embodiments of this application, at least one first baffle 130 is provided inside the air outlet duct 100. The first baffle 130 is perpendicular to the extension direction of the air outlet duct 100, and each first baffle 130 is provided with a first through hole 131.

[0076] In actual use, due to the different positions of the air outlet duct 100 and the air inlet 111, the airflow distribution in the air outlet duct 100 is uneven. By setting the first baffle 130, the airflow flows through the first through hole 131, which plays a certain role in slowing down and obstructing the airflow, thus preventing most or almost all of the gas in the air outlet duct 100 from being blown to the end of the air outlet 100 and then blown out from the air outlet 112, thereby avoiding uneven airflow.

[0077] According to some embodiments of this application, there can be multiple first baffles 130, which are arranged at intervals along the extension direction of the air outlet duct 100. The ratio of the total area of ​​the first through holes 131 on the first baffle 130 to the area of ​​the corresponding first baffle 130 gradually increases in the direction away from the air inlet 111. Since the wind speed is higher near the air inlet 111 and lower away from the air inlet 111, this design, by gradually increasing the ventilation area of ​​the first through holes 131 in the direction away from the air inlet 111, can ensure that the air speed is similar near and far from the air inlet 111, resulting in good uniformity of the blown air and improving the user experience.

[0078] Understandably, the ventilation area of ​​the first through hole 131 can be adjusted according to the position of the first baffle 130. This adjustment can be achieved by changing the area of ​​the first through hole 131 or by changing the number of the first through holes 131, thus changing the ventilation area of ​​the first through hole 131. The shape of the first through hole 131 can be circular, elliptical, or square, etc., and this embodiment does not limit this.

[0079] According to some embodiments of this application, the density of the first baffle 130 gradually decreases along the extension direction of the air outlet duct 100 and away from the air inlet 111. The closer to the air inlet 111, the faster the gas flow rate; the denser the first baffle 130 is arranged, the better its obstruction effect on the airflow, preventing most or almost all of the gas in the air outlet duct 100 from being blown to the end of the air outlet duct 100 before being blown out from the air outlet 112. Thus, by adjusting the distribution density of the first baffle 130, the uniformity of airflow distribution within the air outlet duct is further improved, thereby enhancing the user experience.

[0080] Understandably, the density of the first baffle 130 set in the air outlet duct 100 and the cross-sectional area of ​​the first through hole 131 of the first baffle 130 can be designed according to actual needs, so that the uniformity of the gas blown out of the air outlet 112 of the air outlet duct 100 is good.

[0081] According to some embodiments of this application, a second baffle 140 is provided at the air outlet 112, and the second baffle 140 is provided with a second through hole 141. The gas from the air outlet duct 100 passes through the second through hole 141 before being blown out. In this way, the uniformity of gas distribution discharged from the air outlet duct 100 is improved by passing through the second through hole 141.

[0082] According to some embodiments of this application, a third baffle 150 is also provided at the air outlet 112. The third baffle 150 is located outside the second baffle 140, and the air blown out from the second baffle 140 passes through the third baffle 150 before being blown out. This ensures that the air discharged from the air outlet duct 100 undergoes three stages of uniform airflow—the first baffle 130, the second baffle 140, and the third baffle 150—resulting in good uniformity of the air discharged from the air outlet duct 100, reducing the impact on the user, making the airflow felt by the user softer, and improving the user experience. For example, the third baffle 150 can be a filter screen, or it can be provided with a third through hole 151. Both the second through hole 141 and the third through hole 151 can be configured as strip-shaped grille holes, and the length directions of the second through hole 141 and the third through hole 151 are perpendicular to each other.

[0083] refer to Figure 5 According to some embodiments of this application, the air outlet duct 100 includes an air outlet surface, an air outlet 112 is formed on the air outlet surface, and when the air outlet duct 100 is installed at the target object, the air outlet 112 is exposed, and the air outlet surface forms a continuous surface with the side wall surface of the target object located on at least one side of the air outlet 112.

[0084] The target object can be a specific object within the target space, such as a room or a cabinet. In this embodiment, when the air outlet 100 is installed on the target object, the air outlet 112 of the air outlet 100 is exposed, and the plane containing the air outlet 112 forms a continuous surface with the side wall surface of the target object located on at least one side of the air outlet 112 (e.g., ...). Figure 5 As shown), this makes the air duct 100 and the target object appear harmonious from the outside, thus making the air duct 100 look aesthetically pleasing when installed on the target object.

[0085] Specifically, in this embodiment, the plane where the air outlet 112 of the air outlet duct 100 is located can form a substantially continuous surface with the exposed surface of the target object located on one side of the air outlet 112.

[0086] For example, when the cross-section of the air outlet duct 100 is triangular (such as...) Figure 5 As shown), when the target object is the interior wall of the room, it can be set at the position between the top and the side wall of the room, with only the air outlet 112 exposed. The plane where the air outlet 112 is located forms a continuous zigzag surface with the surface of the ceiling and the side wall.

[0087] refer to Figure 6 , Figure 7 and Figure 8 When the cross-section of the air outlet duct 100 is quadrilateral, two of its sides can be installed with the top and side wall of the target object, while the other two sides can have an air outlet 112 installed at one location or at both locations.

[0088] refer to Figure 6 and Figure 7 Furthermore, when the cross-section of the air outlet duct 100 is quadrilateral, the plane where the air outlet 112 is located and the side wall surface of the target object located around the air outlet 112 form a substantially continuous surface. In this embodiment, the plane where the air outlet 112 is located and the side wall surface of the target object near the air outlet 112 are on the same plane. In this case, a mounting groove needs to be opened at the target object to embed the air outlet duct 100 into the mounting groove, with only the air outlet surface or the air outlet 112 exposed.

[0089] More specifically, the continuity described in this embodiment does not mean that the air outlet 112 or the air outlet surface must be strictly on the same plane, curved surface, or folded surface as the outside of the side wall. When the air outlet 112 or the air outlet surface 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.

[0090] In this way, the air outlet surface and the side wall surface of the target object form a continuous plane, which can reduce the energy loss and turbulence caused by the airflow hitting the side wall, and also achieve seamless connection between the air outlet 112 and the installation environment. While improving the airflow uniformity and cooling / heating effect, it also achieves the invisible integration of the air conditioner 200 equipment with the home scene.

[0091] refer to Figure 9 , Figure 10 , Figure 11 and Figure 12 Secondly, this application embodiment also provides an air conditioner 200, which may include: a body 210, the aforementioned air outlet duct 100 and air supply duct 220.

[0092] The air outlet duct 100 includes an air outlet surface, and an air outlet 112 is formed on the air outlet surface. When the air outlet duct 100 is installed at the target object, the air outlet 112 is exposed, and the air outlet surface forms a continuous surface with the side wall surface of the target object located on at least one side of the air outlet 112. The air supply duct 220 is connected to the air inlet 111 of the body 210 and the air outlet duct 100, respectively. After the gas is heat-exchanged through the body 210, it flows into the air outlet duct 100 through the air supply duct 220 and is discharged to the target space through the air outlet 112.

[0093] The air conditioner 200 of this application uses the aforementioned air outlet duct 100, which is formed by connecting multiple air outlet modules 110 through a connecting module 120. This allows for adjustment of the specific dimensions of the air outlet duct 100 according to the actual needs of the target space, selecting the appropriate number of air outlet modules 110 and connecting them through the connecting module 120. On one hand, this facilitates the integration of the air outlet duct 100 of the air conditioner 200 with the home decoration environment, improving the overall aesthetics and thus increasing user satisfaction. Furthermore, the air outlet surface forms a continuous plane with the side wall surface of the target object, reducing energy loss and turbulence caused by airflow impacting the side wall, and achieving seamless connection between the air outlet 112 and the installation environment. This enhances airflow uniformity and cooling / heating effects while achieving an invisible integration of the air conditioner 200 with the home environment.

[0094] In some embodiments, the unit 210 is located outside the target space, while the air outlet duct 100 is located inside the target space. Thus, by placing the air conditioner unit 210 outside the target space and the air outlet duct 100 inside the target space, synergistic optimization of the air conditioner's operation and user experience is achieved. The external unit 210 effectively isolates noise sources such as the compressor and fan, significantly reducing indoor noise pollution. Simultaneously, the external space can be utilized to improve the air conditioner's heat dissipation, increasing cooling / heating efficiency and extending the lifespan of core components. The internal air outlet duct 100 reduces temperature drop or rise losses during airflow, thereby improving temperature control accuracy and response speed.

[0095] In one specific embodiment, the unit body 210 may include an evaporator 211, a condenser 212, a compressor 213, and a first fan 214. That is, the unit body 210 includes the components of the indoor and outdoor units of a conventional air conditioner 200. The air supply duct 220 may include an air inlet duct 220a and a return air duct 220b. The air supply duct 220 delivers gas from the unit body 210 to the target space through the air inlet duct 220a, and simultaneously returns gas from the target space to the unit body 210 through the return air duct 220b. In other words, the air conditioner 200 in this embodiment places the evaporator 211, condenser 212, compressor 213 and fan of the traditional indoor and outdoor units in the same machine. It only delivers gas to the target space through the air supply duct 220 and exhausts air through the air outlet duct 100. This can effectively reduce the size of the indoor unit. At the same time, since there is only the air outlet duct 100 and no evaporator 211 and fan in the indoor unit, the air conditioner 200 is quieter when blowing air in the target space, thus improving the user experience.

[0096] The air conditioner 200 of this application externalizes the core components such as the heat exchanger of a traditional air conditioner and delivers air through the air supply duct 220. With the addition of the air outlet duct 100, it can be made in a small volume, thereby improving its integration with the home environment.

[0097] refer to Figure 13 Specifically, in this embodiment, a body 210 can be equipped with one air supply duct 220. Of course, in other embodiments, a body 210 can be equipped with multiple air supply ducts 220.

[0098] refer to Figure 14 Furthermore, each air supply duct 220 may include a main pipe 221 and at least one branch pipe 222. One end of each branch pipe 222 is connected to the main pipe 221, and the other end is connected to the corresponding target space and connected to the air outlet duct 100 to supply air to the target space.

[0099] When a unit 210 is equipped with one air supply duct 220 and there are multiple target spaces, one main pipe 221 and multiple branch pipes 222 can be used to supply air to different target spaces. When a unit 210 is equipped with multiple air supply ducts 220 and there are multiple target spaces, each air supply duct 220 can include one main pipe 221, and the number of air supply ducts 220 is matched according to the number of target spaces and the number of target spaces. Each air supply duct 220 can supply air to one of the target spaces.

[0100] refer to Figure 12 In another specific embodiment, the air supply duct 220 may include a wall-penetrating section 223, which is used to pass through the wall so that the end of the air supply duct 220 extends into the target space. The ratio of the cross-sectional area of ​​the wall-penetrating section 223 to the power of the air conditioner 200 is less than or equal to 57.37 cm² / kW, wherein the cross-sectional area of ​​the wall-penetrating section 223 is less than or equal to 200 cm² / kW. 2 .

[0101] Specifically, in this embodiment, the ratio of the cross-sectional area of ​​the wall-penetrating section 223 of the air supply duct 220 to the power of the air conditioner 200 is less than or equal to 57.37 cm² / kW. For example, when the power of the air conditioner 200 is 1.5 horsepower or higher, the upper limit of the cross-sectional area of ​​the corresponding wall-penetrating section 223 is 200 cm² / kW. 2 When the power of the air conditioner 200 is smaller, the cross-sectional area of ​​its wall-penetrating section 223 can be smaller.

[0102] Understandably, the cross-sectional shape of the wall-penetrating segment 223 can be circular, square, or other shapes. Furthermore, most general wall-penetrating holes are circular; therefore, the wall-penetrating segment 223 in this embodiment is preferably circular. Preferably, the wall-penetrating segment 223 of the air conditioner 200 in this embodiment is circular, and the cross-sectional area of ​​the wall-penetrating segment 223 is less than or equal to 200 cm².2 That is, the diameter is less than or equal to 160mm.

[0103] Specifically, in this embodiment, each air supply duct 220 needs to pass through the wall to enter the target space. Therefore, each air supply duct 220 in this embodiment may include a wall-penetrating section 223. In this embodiment, the wall-penetrating section 223 may be circular, and its diameter is less than or equal to 160mm. Furthermore, the diameter of the wall-penetrating section 223 is designed to match the power of the air conditioner 200, which is greater than 1.5 horsepower. In this way, the power requirements of the air conditioner 200 are met, while also ensuring that the wall-penetrating hole is not too large.

[0104] Continue to refer to Figure 12 In some embodiments, each main pipe 221 and branch pipe 222 may include a pipe body 221a and a first partition 221b, wherein the first partition 221b located inside the pipe body 221a extends in a direction parallel to the extension direction of the pipe body 221a, dividing the pipe body 221a into an air inlet duct 220a and an air return duct 220b.

[0105] More specifically, the cross-sectional areas of the air intake duct 220a and the return air duct 220b can be the same. This ensures that the air volume of the intake and return air is equivalent.

[0106] When the air supply duct 220 includes a main pipe 221 and a branch pipe 222, the air inlet duct 220a of the main pipe 221 and the air inlet duct 220a of the branch pipe 222 are connected, and the return air duct 220b of the main pipe 221 and the return air duct 220b of the branch pipe 222 are connected.

[0107] Specifically, when the air supply duct 220 in this embodiment includes a main pipe 221 and a branch pipe 222, the wall penetration section 223 is located at the branch pipe 222.

[0108] More specifically, in this embodiment, the cross-section of the air supply duct 220 at the wall penetration section 223 can be designed as circular, while the ducts at other locations can be designed as circular or other shapes. For example, the duct between the wall penetration section 223 and the unit body 210 can be designed as square, such as rectangular or square. This design makes the air supply duct 220 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 223.

[0109] As a specific embodiment of this application, the air supply duct 220 of this embodiment is provided with a heat insulation layer (not shown in the figure) on its pipe wall. The heat insulation layer can keep the gas inside the air supply duct 220 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.

[0110] As a specific embodiment of this application, the air supply duct 220 of this embodiment is formed by one or more duct units. When the air supply duct 220 is formed by connecting multiple duct units together, the multiple duct units are interlocked and spliced ​​together to form the entire air supply duct 220. Specifically, retaining rings are provided at the connection positions between the duct units, and the retaining rings interlock and seal the ends of the duct units on both sides.

[0111] As a specific embodiment of this application, each air supply duct 220 in this embodiment is provided with an air outlet duct 100 at its end, which is connected to the air inlet duct 220a. The extension direction of the air outlet duct 100 is parallel to the air outlet direction of the air inlet duct 220a. An air outlet 112 is provided at the air outlet duct 100. The gas in the air inlet duct 220a flows into the air outlet duct 100 and is then blown out through the air outlet 112. Specifically, the air supply duct 220 in this embodiment is provided with an air outlet duct 100 at its end. When the gas is transported to the target space by the air supply duct 220, it is then blown out through the air outlet duct 100. The position and direction of the gas flow can be controlled by the air outlet duct 100.

[0112] Specifically, in this embodiment, the direction in which the air outlet duct 100 extends is parallel to the direction of air outlet, which can minimize the loss of gas energy.

[0113] In addition, the cross-sectional area of ​​the air outlet duct 100 in this embodiment is larger than the cross-sectional area of ​​the end of the air supply duct 220, so as to avoid gas energy loss and turbulence.

[0114] Specifically, in this embodiment, the air outlet 112 is located on the side wall of the air outlet duct 100 parallel to its extension direction. This ensures that the direction of the finally blown-out gas is perpendicular to the extension direction of the air outlet duct 100.

[0115] Of course, in other embodiments, the air outlet 112 and the air outlet direction can be adaptively adjusted to meet different air outlet requirements.

[0116] Specifically, when the air supply duct 220 includes a main pipe 221 and branch pipes 222, each branch pipe 222 that delivers air to the target space is connected to an air outlet duct 100 at its end.

[0117] As a specific embodiment of this application, such as Figure 10 and Figure 11 As shown, the body 210 of this embodiment may have a housing 215. The housing 215 may include a second partition 216. The second partition 216 divides the housing 215 into a first receiving cavity 2151 located above and a second receiving cavity 2152 located below. The evaporator 211 and the first fan 214 are located in the first receiving cavity 2151, and the condenser 212 is located in the second receiving cavity 2152.

[0118] Specifically, in this embodiment, the housing 210 can be provided with a second partition 216, which divides the shell 215 into two receiving cavities. These two cavities are respectively equipped with an evaporator 211 and a condenser 212. In this embodiment, the evaporator 211 is located in the upper first receiving cavity 2151, which is connected to the air supply duct 220. This allows gas to exchange heat through the evaporator 211 before flowing out through the air supply duct 220 into the target space. The condenser 212, located in the second receiving cavity 2152, exchanges heat with the liquid in the evaporator 211, ensuring the evaporator 211 reaches a suitable heat exchange temperature. The second partition 216 also prevents gas from passing through both the space containing the evaporator 211 and the space containing the condenser 212, thus avoiding any impact on the heat exchange effect.

[0119] More specifically, in this embodiment, at least one fourth through hole 2161 is provided at the second partition 216, and the fourth through hole 2161 is located at a position corresponding to the location of the condenser 212. Specifically, since condensate easily forms in the evaporator 211 when exchanging heat with the gas, the condensate will flow down the evaporator 211 and drip below. A drip tray can be provided below the evaporator 211, or the second partition 216 can serve as the drip tray. In this embodiment, the fourth through hole 2161 is provided at the second partition 216, allowing the condensate to drip down along the fourth through hole 2161. The fourth through hole 2161 is located above the condenser 212, so that the condensate directly drips onto the condenser 212, thereby cooling the condenser 212 and improving the overall energy efficiency of the unit.

[0120] In another specific embodiment of this application, the second partition 216 is inclined, and the second partition 216 is inclined toward the side where the condenser 212 is located. Specifically, the second partition 216 in this embodiment can be set with an inclination angle, so that the condensate can flow along the second partition 216 to one side and eventually drip onto the condenser 212, thereby cooling the condenser 212 and improving the energy efficiency of the whole machine.

[0121] As a specific embodiment of this application, the housing 215 of this embodiment may further include a third partition 217 disposed in the first receiving cavity 2151. The third partition 217 divides the first receiving cavity 2151 into a first sub-cavity and a second sub-cavity. An evaporator 211 is disposed in the first sub-cavity, and a first fan 214 is disposed in the second sub-cavity. An air inlet duct 220a is connected to the second sub-cavity, and an air return duct 220b is connected to the first sub-cavity. A fifth through hole 2171 is provided at the third partition 217 so that the air flowing into the first sub-cavity from the air return duct 220b flows to the second sub-cavity through the fifth through hole 2171 after heat exchange by the evaporator 211, and then the first fan 214 blows the gas into the air inlet duct 220a.

[0122] Specifically, in this embodiment, the first receiving cavity 2151 is divided into a first sub-cavity and a second sub-cavity by the third partition 217, so that the inlet of the air inlet duct 220a is connected to the second sub-cavity, while the outlet of the return air duct 220b is connected to the first sub-cavity, thereby separating the exhaust gas and the return gas and preventing the gas from flowing into the air inlet duct 220a without heat exchange, which would affect the exhaust temperature.

[0123] Furthermore, in this embodiment, a fifth through hole 2171 is provided at the third partition 217, and the first fan 214 can be a centrifugal fan. The air inlet of the centrifugal fan is located at the fifth through hole 2171, and the air outlet of the centrifugal fan can be directly connected to the inlet of the air inlet duct 220a, directly blowing the gas in the first sub-cavity into the air inlet duct 220a.

[0124] 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 2151, 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 214 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 intake duct 220a.

[0125] Specifically, in this embodiment, a fresh air inlet is provided on the side wall of the first receiving cavity 2151. When the centrifugal fan blows the gas from the first sub-cavity into the air inlet duct 220a, due to the negative pressure, outside air will enter the second sub-cavity through the fresh air inlet and then be blown into the air inlet duct 220a by the centrifugal fan.

[0126] 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 are blown into the air intake duct 220a and then into the target space. 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 is blown into the target space.

[0127] Specifically, in this embodiment, the fresh air inlet and fresh air valve can be located on the side wall of the first sub-cavity or on the side wall of the second sub-cavity. Preferably, the fresh air inlet and fresh air valve are located on the side wall of the first sub-cavity, so that the fresh air can pass through the evaporator 211 together with the gas flowing in through the return air duct 220b for heat exchange before being blown into the air inlet duct 220a by the centrifugal fan.

[0128] As a specific embodiment of this application, the second receiving cavity 2152 may further include a fourth partition 218, which divides the second receiving cavity 2152 into a third sub-cavity and a fourth sub-cavity. The evaporator 211 is located in the third sub-cavity, and the compressor 213 is located in the fourth sub-cavity. The third sub-cavity may further include a second motor (not shown in the figure) and a second fan 219. The second motor drives the second fan 219 to rotate to dissipate heat from the condenser 212. The second motor drives the second fan 219 to rotate, and the second fan 219 carries away the heat from the condenser 212 during rotation, preventing the condenser 212 from becoming too hot.

[0129] As a specific embodiment of this application, at least one side wall of the third sub-cavity is provided with an air outlet, and a grille 2153 is provided at the air outlet. The condenser 212 is arranged around the side wall of the third sub-cavity without an air outlet. Specifically, the grille in this embodiment can prevent external dust from entering the second receiving cavity 2152, and can also protect the outside world to prevent the fan from causing harm to people outside.

[0130] Specifically, the second fan 219 in this embodiment can be an axial flow fan.

[0131] As a specific embodiment of this application, the air intake volume of the air supply duct 220 in this embodiment is 650m³. 3 / h~11000m 3 / h. For example, the intake air volume can be 650 m³ / h. 3 / h, 700m 3 / h, 750m 3 / h、800m 3 / h、900m 3 / h, 1000m 3 / h or 1100m 3 / h etc.

[0132] Specifically, when the fresh air valve in this embodiment is closed, and the air is in complete internal circulation, and the wall-penetrating section 223 of the air intake duct is limited to a diameter of 160mm, the air intake volume in this embodiment can reach 650m³ / h. 3 / h~700m 3 / h. When the fresh air valve in this embodiment is opened, combined with the internal circulation and external fresh air, the air intake volume of the air intake duct in this embodiment can reach 1100m³ / h. 3 / h or even higher. Specifically, the intake air volume is related to the diameter of the air supply duct 220 and the power of the centrifugal fan. Of course, the size of the fresh air inlet will also have a certain impact on the intake air volume.
