Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an air conditioner. Background Technology

[0002] As living standards improve, users have higher requirements for the comfort of air conditioning. They expect air conditioners to regulate indoor temperature while avoiding the discomfort caused by direct airflow, achieving a gentle and even airflow distribution, and creating a healthy and comfortable indoor environment.

[0003] However, traditional household air conditioners, such as wall-mounted and floor-standing units, mostly adopt a single-sided direct-blowing air supply structure. Cold or hot air is blown out at high speed through a single air outlet. This air supply method will cause uneven indoor air flow, easily forming obvious airflow dead zones and temperature differences in the indoor space, making it difficult to achieve a uniform temperature field distribution, resulting in a poor user experience. Utility Model Content

[0004] This application discloses an air conditioner that can improve the uniformity of air supply, so as to avoid problems such as uneven indoor air flow, significant temperature difference and discomfort from direct airflow as much as possible, thereby improving the user experience.

[0005] To achieve the above objectives, this application discloses an air conditioner, comprising:

[0006] An integrated air conditioner unit, wherein the integrated air conditioner unit is installed outdoors, and the integrated air conditioner unit includes:

[0007] A housing, wherein an air duct is formed within the housing, and the air duct has a first air inlet and a first air outlet;

[0008] A heat exchange module is disposed inside the housing and is used to regulate the temperature of the air entering the air duct through the first air inlet.

[0009] An air duct, one end of which is connected to the first air outlet and the other end of which is configured to extend into the interior space through the wall of the house;

[0010] An air supply duct, configured to be installed in the ceiling of the building, the air supply duct comprising:

[0011] The main body of the air duct is arranged around the perimeter edge of the suspended ceiling;

[0012] The second air inlet is connected to one end of the air outlet duct that extends into the indoor space, so that the air processed by the heat exchange module can enter the air duct body through the second air inlet.

[0013] The second air outlet includes multiple second air outlets, which are disposed on the main body of the air duct and are arranged at intervals along the extension direction of the main body of the air duct, so that the air in the air supply duct can be blown into the indoor space through the multiple second air outlets.

[0014] In this way, the main body of the air duct is set around the perimeter of the ceiling, and with multiple second air outlets arranged at intervals along its extension direction, the air after heat exchange can be diffused radially from all sides of the room to the center, so that the temperature of each corner of the room can be quickly and evenly regulated. In addition, the surrounding air supply duct allows the air to cover the entire indoor space more quickly and evenly, accelerating the indoor temperature regulation speed, improving the uniformity of the temperature field, reducing the temperature difference between different areas, and by distributing the total air supply to multiple air outlets, strong winds can be avoided from blowing directly on users, improving the user experience.

[0015] This application also provides an air conditioner in which the second air outlet is in the form of a hole, or in the form of a slit.

[0016] In this way, numerous small holes disperse the airflow, transforming the concentrated large volume of air into multiple weak airflows. This significantly reduces the speed of the airflow as it exits the duct, preventing it from blowing directly onto people. Compared to large-diameter air outlets, the perforated design increases the contact area between the airflow and the duct wall, providing a buffering and noise reduction effect. The friction and disturbance generated when the airflow passes through the small holes are more dispersed, preventing the formation of strong eddy noise and creating a quiet indoor environment. The slender shape of the slits allows for precise control of the airflow direction, causing the air to blow out in a flat shape along the length of the slit. This can guide the airflow to specific areas. By adjusting the angle of the slits, the airflow can be blown horizontally along the ceiling for long-distance delivery. The cool air diffuses along the ceiling and naturally sinks, thus evenly covering the entire space and effectively avoiding the uneven heating and cooling problems caused by traditional air conditioners blowing directly onto the floor.

[0017] This application also provides an air conditioner, wherein the air duct body includes:

[0018] The first air duct sidewall is fixed to the ceiling;

[0019] The second air duct sidewall is connected to the first air duct sidewall and fixed to the side wall of the indoor space;

[0020] The third air duct sidewall has its opposite ends connected to the first air duct sidewall and the second air duct sidewall, respectively. The third air duct sidewall faces the indoor space and is curved. Multiple second air outlets are provided on the third air duct sidewall.

[0021] In this way, by making the third air duct curved, it can naturally guide the airflow within the duct. Compared with traditional flat sidewalls, the curved surface can better conform to the curve trajectory of airflow, reducing turbulence and resistance caused by the collision between airflow and sidewalls. When air flows through the curved third sidewall, it will smoothly diffuse and blow out along the curvature of the surface, avoiding airflow accumulation or rebound caused by right angles or flat turns. This allows the air to be delivered to the indoor space through the second air outlet in a more uniform and gentle state, further improving the comfort and uniformity of air supply.

[0022] This application also provides an air conditioner, wherein the third air duct sidewall includes:

[0023] The first air outlet surface, the upper edge of the first air outlet surface is connected to the side wall of the first air duct;

[0024] The second air outlet surface has its lower edge connected to the side wall of the second air duct. The upper edge of the second air outlet surface and the lower edge of the first air outlet surface are opposite to each other and spaced apart. The upper edge of the second air outlet surface and the lower edge of the second air outlet surface together form a strip-shaped air outlet. Both the first air outlet surface and the second air outlet surface are provided with multiple second air outlets.

[0025] In this way, the strip-shaped air outlet can serve as the main air outlet to quickly deliver the air in the duct body to the indoor space, while the second air outlet on the first air outlet surface (the upper edge of which is connected to the side wall of the first air duct) delivers air upward or horizontally, and the airflow can spread far along the ceiling. The second air outlet on the second air outlet surface (the lower edge of which is connected to the side wall of the second air duct) delivers air downward or diagonally downward, thereby achieving air delivery to the indoor space without dead angles, ensuring that every corner of the room can obtain uniform temperature regulation, eliminating airflow dead angles, and achieving a comfortable experience throughout the entire house.

[0026] This application also provides an air conditioner, wherein the first air outlet protrudes toward the indoor space and the second air outlet protrudes toward the interior of the air supply duct.

[0027] In this way, the protruding shape of the first air outlet can be naturally connected with the three-dimensional design of the ceiling. For example, in stepped or curved ceilings, it can be cleverly embedded into the concave and convex structure of the ceiling, making the air outlet and the ceiling design blend together, hiding the boundary of the air duct and enhancing the overall sense of space. The second air outlet protrudes into the air duct, which can make the external outline align with the decorative lines of the wall, forming a smooth line transition when viewed from the side, avoiding the abruptness of traditional flat air outlets.

[0028] This application also provides an air conditioner in which, in a direction perpendicular to the plane of the second air duct sidewall, the upper edge of the second air outlet surface is located in front of the lower edge of the first air outlet surface.

[0029] In this way, the airflow is not blocked by the first air outlet, allowing the airflow to be sprayed more directly towards the front of the room, reducing refraction and scattering, and accurately guiding the airflow to the core activity area of ​​the room. In terms of range, because the upper edge of the second air outlet is forward, the starting position of the airflow from the strip air outlet is closer to the room, effectively shortening the distance the airflow has to reach the target area and reducing energy loss during transmission. Combined with optimized airflow guidance, the airflow can be delivered over a longer distance, effectively covering a larger room space, and solving the problem of insufficient airflow at the far end of traditional air outlets in large spaces.

[0030] This application also provides an air conditioner, wherein the main body of the air duct is arranged around the connection edge between the ceiling and the wall, forming a closed shape.

[0031] In this way, the closed-loop air duct layout allows multiple air outlets to be evenly distributed around the room, achieving 360-degree surround air supply, effectively eliminating dead air zones and temperature differences in the room, and avoiding the problems of local overheating or overcooling caused by traditional single-sided air supply.

[0032] This application also provides an air conditioner, wherein the integrated air conditioner further includes:

[0033] A mixing chamber is formed inside the housing and communicates with the air duct;

[0034] The return air duct has one end extending into the indoor space and the other end connected to the mixing chamber. The return air duct is used to introduce indoor air into the mixing chamber so that the indoor air entering the mixing chamber through the return air duct is mixed with the air processed by the heat exchange module, and the mixed air enters the supply air duct.

[0035] In this way, the return air duct introduces indoor air into the mixing chamber, where it mixes with the air processed by the heat exchange module. This avoids directly supplying air with large temperature and humidity differences into the room, reducing thermal shock. For example, during summer cooling, it avoids discomfort caused by direct cold air blowing, making the supply air temperature closer to the human comfort range and improving physical comfort. Furthermore, the temperature and humidity of the indoor return air are used to pre-regulate the air processed by the heat exchange module, reducing the energy consumption of the air conditioning system.

[0036] This application also provides an air conditioner, wherein the integrated air conditioner further includes:

[0037] A fresh air module, wherein the fresh air module is used to introduce outdoor air into the indoor space, the fresh air module comprising:

[0038] Fresh air inlet, which is provided on the housing, allows outdoor air to enter the housing through the fresh air inlet;

[0039] The fresh air duct has one end connected to the fresh air inlet and the other end connected to the mixing chamber, so that the fresh air introduced by the fresh air module can be mixed with the indoor air entering the mixing chamber through the return air duct, and the mixed air enters the air supply duct in sequence through the first air outlet and the second air inlet.

[0040] In this way, fresh outdoor air can be continuously introduced through the fresh air inlet on the shell, effectively diluting the concentration of harmful gases such as carbon dioxide and formaldehyde in the room, solving the problem of turbid air in enclosed spaces. Furthermore, the fresh air and indoor return air are mixed in the mixing chamber, and the temperature and humidity of the indoor return air can be used to pre-adjust the fresh air, making the mixed air closer to the set temperature, thus improving the accuracy and efficiency of temperature and humidity regulation.

[0041] This application also provides an air conditioner, which further includes:

[0042] A blower fan is installed inside the air supply duct and is used to drive the air in the air supply duct to blow into the indoor space through multiple second air outlets.

[0043] In this way, the air supply fan uses mechanical power to force the air to flow, which counteracts the friction and local resistance of the air supply duct (especially long or multi-bend ducts), ensuring that the air can be delivered to various areas of the room over long distances and stably, avoiding the problem of air supply attenuation caused by natural convection or insufficient air pressure.

[0064] 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 only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0065] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0067] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts.

[0068] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components whose specific types and structures may be the same or different, and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0069] As mentioned in the background technology, traditional household air conditioners, such as wall-mounted units and floor-standing units, mostly adopt a single-sided direct-blowing air supply structure. Cold or hot air is blown out at high speed through a single air outlet. This air supply method will cause uneven indoor air flow, easily forming obvious airflow dead zones and temperature differences in the indoor space, making it difficult to achieve a uniform temperature field distribution, resulting in a poor user experience.

[0070] To address the aforementioned issues, this application provides an air conditioner comprising an integrated outdoor air conditioning unit and an indoor air supply duct. The main body of the air supply duct is arranged around the perimeter of the ceiling and is equipped with multiple second air outlets spaced apart along its extension direction. This allows the air, after heat exchange, to radiate outwards from the perimeter of the room towards the center, enabling the air to cover the entire indoor space more quickly and evenly. This accelerates the indoor temperature regulation, improves the uniformity of the temperature field, reduces temperature differences between different areas, and by distributing the total air supply to multiple air outlets, it avoids strong winds blowing directly on users, thus improving the user experience.

[0071] The following will describe specific embodiments and appendices. Figure 1-11 The technical solution of the air conditioner in this application will be further explained.

[0072] like Figure 1 and Figure 2 As shown, the air conditioner 1 includes an integrated air conditioner unit 10, which is installed outdoors.

[0073] like Figure 3 As shown, the integrated air conditioner 10 may include a housing 10a, within which an air duct is formed. The air duct has a first air inlet and a first air outlet 12a. The housing 10a is the main external structure of the integrated air conditioner 10, serving to protect internal components, support the installation of various parts, and guide airflow. It is typically made of durable materials with certain thermal insulation properties, such as sheet metal (galvanized steel sheet, etc.) or engineering plastics. The air duct is the channel inside the housing 10a used to guide airflow and is a key path for achieving air transport and heat exchange.

[0074] like Figure 3 As shown, the integrated air conditioner 10 may also include a heat exchange module 11, which is disposed inside the housing 10a. The heat exchange module 11 is used to regulate the temperature of the air entering the air duct through the first air inlet. The heat exchange module 11 is the core component of the integrated air conditioner 10 that enables temperature regulation. It is located in the air duct inside the casing 10a. Its main working principle is to control the air temperature through heat exchange between the refrigerant and the air. In cooling mode, the heat exchange module 11 acts as an evaporator, where the liquid refrigerant evaporates and absorbs heat, cooling the air flowing through the air duct and lowering its temperature. In heating mode, the heat exchange module 11 acts as a condenser, where the high-temperature, high-pressure gaseous refrigerant releases heat, heating the air passing through. The heat exchange module 11 is usually composed of heat exchange tubes (such as copper tubes) and fins. The refrigerant flows through the heat exchange tubes, and the fins are used to increase the contact area with the air and improve the heat exchange efficiency. Thus, through the coordinated work of the compressor, expansion valve, and other components with the heat exchange module 11, a complete cooling or heating cycle system is formed, which accurately regulates the temperature of the air entering the air duct to meet the needs of the indoor environment.

[0075] like Figure 1 and Figure 2 As shown, the integrated air conditioner 10 may also include an air outlet duct 12, one end of which is connected to an air outlet, and the other end is configured to extend into the indoor space through the wall of the house 2. The air outlet duct 12 is used to deliver air processed by the heat exchange module 11 to the indoor space.

[0076] For example, the integrated air conditioner 10 can be an integrated dual-duct air conditioner 1, which is divided into upper and lower parts by a middle partition. The upper part of the air conditioner can be considered as the "indoor side", which mainly undertakes the functions of air handling and output. The heat exchanger is set here as the core component, and it performs precise heating or cooling of the air through refrigerant circulation. At the same time, the indoor side can also be equipped with components such as a fan and air supply duct 100 interface, which deliver the treated air to the indoor space through ducts. The lower part of the air conditioner can be considered as the "outdoor side", where components such as compressor and condenser are arranged in an orderly manner. In cooling mode, the compressor compresses and heats the gaseous refrigerant and sends it to the condenser on the outdoor side, where it releases heat to the outside through heat exchange with the outside air. In heating mode, the evaporator on the outdoor side absorbs heat from the low-temperature outside environment to ensure that the indoor side can continuously output warm airflow.

[0077] like Figure 2 As shown, the air conditioner 1 may include an air supply duct 100, which is configured to be installed on the ceiling 21 of the house 2. The ceiling 21 is a decorative structure located at the top of the interior space. It is supported by a keel frame and fixes surface materials such as gypsum board and aluminum panels, serving to conceal pipes, beautify the space, and optimize functions. The air supply duct 100 may be installed between the ceiling 21 and the ceiling, or on the side of the ceiling facing the interior space.

[0078] The air supply duct 100 may include a duct body 110, which is arranged around the side edge of the suspended ceiling 21.

[0079] like Figure 2 , Figure 4 and Figure 5 As shown, the air supply duct 100 may also include a second air inlet 120, which is connected to one end of the air outlet duct 12 that extends into the indoor space, so that the air processed by the heat exchange module 11 can enter the duct body 110 through the second air inlet 120.

[0080] like Figure 5 As shown, the air supply duct 100 may also include a second air outlet 130. The second air outlet 130 includes multiple outlets, which are disposed on the duct body 110 and arranged at intervals along the extension direction of the duct body 110, so that the air in the air supply duct 100 can be blown into the indoor space through the multiple outlets 130.

[0081] Thus, the main air duct 110 is arranged around the perimeter of the ceiling 21, and is equipped with multiple second air outlets 130 arranged at intervals along its extension direction. This allows the air after heat exchange to be diffused radially from all sides of the room to the center. Compared with the "near cold and far hot" phenomenon caused by the one-sided direct blowing of traditional air conditioners, this method effectively shortens the airflow transmission distance, avoids energy attenuation caused by long-distance airflow, and allows the temperature of each corner of the room to be quickly and evenly regulated. In addition, the surrounding air supply duct 100 allows the air to cover the entire indoor space more quickly and evenly, accelerates the indoor temperature regulation speed, improves the uniformity of the temperature field, reduces the temperature difference between different areas, and by distributing the total air supply to multiple air outlets, it can avoid strong winds blowing directly on users and improve the user experience.

[0082] Furthermore, the integrated air conditioner 10 is installed outdoors, avoiding the problem of traditional wall-mounted and cabinet units occupying wall and floor space, making it especially suitable for small apartments or places with high space utilization requirements; the air supply duct 100 is set on the ceiling 21, which will not damage the indoor visual effect, ensuring the integrity and aesthetics of the decoration style, and there is no need for complicated indoor pipeline layout, reducing the impact of installation on decoration.

[0083] In addition, the integrated air conditioner 10 is installed outdoors, physically isolating the compressor, fan and other main operating components from the indoor space. This cuts off the noise transmission path from the sound source. During the operation of the integrated air conditioner 10, the high-frequency vibration noise of the compressor and the airflow noise generated by the fan rotation are blocked outdoors. This avoids the noise interference caused by the operation of the motor 17 and the flow of refrigerant in the indoor unit of the traditional split air conditioner 1, thus ensuring that the indoor environment is not affected by the operating noise of the air conditioner 1. This meets the needs of places with high requirements for quiet environment, such as bedrooms and studies, and provides users with a comfortable and quiet rest and work space.

[0084] In some possible embodiments, such as Figure 5 As shown, the second air outlet 130 is perforated. "Perforated" refers to the radial dimensions of the second air outlet 130 being relatively similar in all directions. The perforated second air outlet 130 can be designed as a regular geometric shape such as circular, square, or rhomboid, and there can be multiple second air outlets 130. When there are multiple outlets, they can be arranged in irregular combinations such as plum blossom or honeycomb patterns.

[0085] In this way, numerous small holes disperse the airflow, transforming the concentrated large volume of air into multiple weak airflows. This significantly reduces the speed of the airflow as it exits the duct, preventing it from blowing directly onto the human body. Compared to large-diameter air outlets, the perforated design increases the contact area between the airflow and the duct wall, providing a buffering and noise reduction effect. The friction and disturbance generated when the airflow passes through the small holes are more dispersed, preventing the formation of strong eddy noise and creating a quiet indoor environment. Furthermore, the holes can be flexibly arranged according to the shape of the ceiling 21 and the interior decoration style, such as being distributed in straight lines, wavy lines, or other artistic patterns along the main body of the duct 110, which not only meets functional requirements but also enhances aesthetics.

[0086] In some possible embodiments, the second air outlet 130 is slit-shaped. The slit-shaped second air outlet 130 can be designed as a long and thin strip structure, or it can be designed as a combination of multiple short slits.

[0087] In this way, the slender shape of the slit can precisely control the direction of airflow, allowing the air to be blown out in a flat shape along the length of the slit. This can guide the airflow to a specific area. By adjusting the angle of the slit, the airflow can be blown out horizontally along the ceiling to achieve long-distance delivery. After the cold air diffuses along the ceiling, it naturally sinks, thus evenly covering the entire space and effectively avoiding the problem of uneven heating and cooling caused by traditional air conditioners blowing directly on the ground.

[0088] In some possible embodiments, such as Figure 6 , Figure 7 as well as Figure 8 As shown, the air duct body 110 may include a first air duct sidewall 110a, which is fixed to the ceiling 21.

[0089] like Figure 6 , Figure 7 as well as Figure 8 As shown, the air duct body 110 may also include a second air duct sidewall 110b, which is connected to the first air duct sidewall 110a and fixed to the side wall of the indoor space.

[0090] like Figure 6 , Figure 7 as well as Figure 8 As shown, the main body of the air duct 110 may also include a third air duct sidewall 110c. The two opposite ends of the third air duct sidewall 110c are respectively connected to the first air duct sidewall 110a and the second air duct sidewall 110b. The third air duct sidewall 110c faces the indoor space and is curved. Multiple second air outlets 130 are disposed on the third air duct sidewall 110c.

[0091] By making the third air duct curved, it can naturally guide the airflow within the duct. Compared with traditional flat sidewalls, the curved surface can better conform to the curve trajectory of airflow, reducing turbulence and resistance caused by airflow collision with the sidewall. When air flows through the curved third sidewall, it will smoothly diffuse and blow out along the curvature of the surface, avoiding airflow accumulation or rebound caused by right angles or flat turns. This allows the air to be delivered to the indoor space through the second air outlet 130 in a more uniform and gentle state, further improving the comfort and uniformity of air supply.

[0092] Furthermore, the shape of the curved surface can change the exit angle and direction of the airflow, delivering air to a wider space. For example, a convex curved surface can cause the airflow to spread outwards in a fan shape, increasing the horizontal coverage area; while a concave curved surface can guide the airflow to tilt downwards and blow outwards, strengthening the vertical air delivery distance, thereby effectively reducing dead air zones in the room and allowing temperature regulation to be quickly achieved in every corner of the room.

[0093] In some possible embodiments, such as Figure 7 , Figure 8 and Figure 9 As shown, the third air duct sidewall 110c may include a first air outlet surface 1101, the upper edge of which is connected to the first air duct sidewall 110a.

[0094] The third air duct sidewall 110c may also include a second air outlet surface 1102. The lower edge of the second air outlet surface 1102 is connected to the second air duct sidewall 110b. The upper edge of the second air outlet surface 1102 and the lower edge of the first air outlet surface 1101 are opposite to each other and spaced apart. The upper edge of the second air outlet surface 1102 and the lower edge of the second air outlet surface 1102 together form a strip-shaped air outlet 1103. The first air outlet surface 1101 and the second air outlet surface 1102 are each provided with a plurality of second air outlets 130.

[0095] In this way, the strip-shaped air outlet 1103 can serve as the main air outlet to quickly deliver the air in the duct body to the indoor space. The second air outlet 130 of the first air outlet surface 1101 (the upper edge of which is connected to the side wall 110a of the first air duct) delivers air upward or horizontally, and the airflow can spread far away along the ceiling 21. The second air outlet 130 of the second air outlet surface 1102 (the lower edge of which is connected to the side wall 110b of the second air duct) delivers air downward or diagonally downward, thereby achieving air delivery to the indoor space without dead angles, ensuring that every corner of the room can obtain uniform temperature regulation, eliminating airflow dead angles, and achieving a comfortable experience throughout the entire house.

[0096] In some possible embodiments, such as Figure 8 As shown, the first air outlet surface 1101 protrudes towards the indoor space, and the second air outlet surface 1102 protrudes towards the interior of the air supply duct 100.

[0097] The protruding shape of the first air outlet surface 1101 can be naturally integrated with the three-dimensional design of the ceiling 21. For example, in stepped or curved ceilings 21, it can be cleverly embedded into the concave and convex structure of the ceiling 21, making the air outlet and the ceiling 21 shape seamless, hiding the boundary of the air duct and enhancing the overall sense of space. The second air outlet surface 1102 protrudes towards the air duct, which can align the external contour with the decorative lines of the wall, forming a smooth line transition when viewed from the side, avoiding the abruptness of traditional straight air outlets. For example, in terms of integration with the light strip 22, the groove or gap space created by the protruding structure provides a position for the installation of the light strip 22. The groove at the junction of the first air outlet surface 1101 and the ceiling 21 can be embedded with the linear LED light strip 22, and the light is softly diffused along the protruding curved surface to form a floating light and shadow effect. The gap between the second air outlet surface 1102 and the wall can also conceal the light strip 22, and the light is projected upward or downward, complementing the three-dimensional shape of the air outlet surface and improving the aesthetics.

[0098] In some possible embodiments, such as Figure 8 As shown, in the direction perpendicular to the plane of the second air duct sidewall 110b, the upper edge of the second air outlet surface 1102 is located in front of the lower edge of the first air outlet surface 1101. That is, in the direction perpendicular to the plane of the second air duct sidewall 110b (which can be understood as the "front and back" direction viewed from the side of the air duct), the upper edge of the second air outlet surface 1102 is positioned further forward (i.e., closer to the side of the indoor space) than the lower edge of the first air outlet surface 1101.

[0099] In this way, the airflow of the first air outlet 1101 is not blocked by the strip-shaped air outlet 1103, allowing the airflow to be sprayed more directly towards the front of the room, reducing refraction and scattering, and accurately guiding the airflow to the core activity area of ​​the room. In terms of range, since the upper edge of the second air outlet 1102 is forward, the starting position of the airflow of the strip-shaped air outlet 1103 is closer to the indoor space, effectively shortening the distance of the airflow to the target area, reducing energy loss during transmission, and combined with the optimized airflow guidance, the airflow can be delivered over a longer distance, effectively covering a larger indoor space, and solving the problem of insufficient airflow at the far end of traditional air outlets in large spaces.

[0100] In some possible embodiments, such as Figure 10 As shown, the main body of the air duct 110 is arranged around the connection edge between the ceiling 21 and the wall, forming a closed shape.

[0101] The air duct is embedded in the junction of the ceiling 21 and the wall, making full use of the hidden space at the corner of the building and avoiding the occupation of the central activity area of ​​the room. For small apartments or spaces with limited ceiling height, it can maximize the release of effective indoor space. In addition, the closed ring design can be seamlessly connected with the interior decoration style, keeping the ceiling clean and beautiful without the need for additional decorations.

[0102] In addition, the closed-loop air duct layout allows multiple air outlets to be evenly distributed around the room, achieving 360-degree surround air supply, effectively eliminating dead air zones and temperature differences in the room, and avoiding the problems of local overheating or overcooling caused by traditional single-sided air supply.

[0103] In some possible embodiments, the integrated air conditioner 10 may further include a mixing chamber formed within the housing 10a and communicating with the air duct.

[0104] like Figure 1 , Figure 2 and Figure 4 As shown, the integrated air conditioner 10 may also include a return air duct 13, one end of which extends into the indoor space and the other end is connected to the mixing chamber. The return air duct 13 is used to introduce part of the indoor air into the mixing chamber so that the indoor air entering the mixing chamber through the return air duct 13 is mixed with the air processed by the heat exchange module 11.

[0105] The return air duct 13 introduces indoor air into the mixing chamber, where it mixes with the air processed by the heat exchange module 11. This avoids directly supplying air with large temperature and humidity differences into the room, reducing thermal shock. For example, during summer cooling, it avoids discomfort caused by direct cold air blowing, making the supply air temperature closer to the human comfort range and improving physical comfort. Furthermore, it uses the temperature and humidity of the indoor return air to pre-regulate the air processed by the heat exchange module 11, reducing the energy consumption of the air conditioning system 1.

[0106] For example, a cylindrical mixing chamber can be provided inside the housing 10a of the air conditioner 1, and placed between the heat exchange module 11 and the air duct. The top of the mixing chamber is provided with multiple evenly distributed air inlets, of which the two larger air inlets are connected to the return air duct 13 and the fresh air duct respectively, and the remaining smaller air inlets are connected to the air outlet of the heat exchange module 11.

[0107] In some possible embodiments, such as Figure 2 As shown, the integrated air conditioner 10 also includes a fresh air module 14, which is used to introduce outdoor air into the indoor space.

[0108] like Figure 3 As shown, the fresh air module 14 may include a fresh air inlet 14a, which is disposed on the housing 10a, and outdoor air enters the housing 10a through the fresh air inlet 14a.

[0109] The fresh air module 14 may also include a fresh air duct, one end of which is connected to the fresh air inlet 14a and the other end of which is connected to the mixing chamber, so that the fresh air introduced by the fresh air module 14 can be mixed with the indoor air that enters the mixing chamber through the return air duct 13, and the mixed air enters the supply air duct 100 through the first air outlet 12a and the second air inlet 120 in sequence.

[0110] Through the fresh air inlet 14a on the housing 10a, fresh outdoor air can be continuously introduced, effectively diluting the concentration of harmful gases such as carbon dioxide and formaldehyde in the room, solving the problem of turbid air in enclosed spaces. Furthermore, the fresh air and indoor return air are mixed in the mixing chamber, and the temperature and humidity of the indoor return air can be used to pre-adjust the fresh air, making the mixed air closer to the set temperature, thus improving the accuracy and efficiency of temperature and humidity regulation.

[0111] For example, the mixing chamber can be annular cylindrical in shape, nested inside the center of the air conditioner housing 10a. Its outer ring wall is fixedly connected to the housing 10a, and the inner ring wall is hollowed out to form an annular air outlet, which is directly connected to the inlet of the air supply duct 100. The top of the mixing chamber is provided with three air inlet interfaces. The central interface at the top is vertically connected to the air outlet of the heat exchange module 11 for introducing processed hot and cold air. The symmetrical interfaces on both sides of the top are respectively connected to the fresh air duct and the return air duct 13. The fresh air duct interface is slightly higher than the return air duct 13 interface, and the height difference is used to achieve natural stratified air intake. A spiral guide plate group is set in the chamber to guide the three air intakes to flow along the spiral path and collide and cut each other to achieve air mixing.

[0112] In some possible embodiments, such as Figure 2 and Figure 4 As shown, the return air duct 13 may include an air filter 13a, which is detachably mounted at the end of the return air duct 13 that extends into the indoor space.

[0113] Air filter 13a can filter pollutants such as dust, hair, pollen, and smoke particles in the return air, preventing pollutants from entering the mixing chamber with the return air, preventing pollutants from accumulating in the air conditioning system 1 or being released back into the room, continuously purifying the circulating air, improving indoor air quality, and the air filter 13a is detachably installed at the end of the return air duct 13 that extends into the indoor space, making it easy to clean and replace the air filter 13a.

[0114] For example, a rectangular filter compartment is provided at the end of the return air duct 13 that extends into the room. The compartment adopts a snap-on or sliding drawer structure. The air filter 13a is flat and embedded in the compartment, closely fitting the inner wall of the return air duct 13 to prevent unfiltered air from bypassing and leaking.

[0115] In some possible embodiments, the fresh air module 14 may also include an air inlet valve, which is located at the fresh air inlet 14a and is used to control the opening degree of the fresh air inlet 14a to adjust the amount of fresh air entering the air.

[0116] In this way, the air inlet valve can adjust the opening degree of the fresh air inlet 14a in real time according to changes in the indoor and outdoor environment and user needs, control the fresh air intake volume, thereby avoiding unnecessary fresh air introduction and reducing the energy consumption of the air conditioning system 1 in processing the temperature and humidity of the fresh air. For example, when the outdoor temperature is too high in summer, the fresh air volume is reduced to reduce the cooling burden; when the outdoor temperature is cold in winter, the fresh air volume is reasonably controlled to reduce heating consumption and achieve energy-saving operation.

[0117] For example, the air inlet valve can consist of multiple horizontally arranged metal or PVC louvers. Each louver is connected to the two side frames via a rotating shaft. One end of the rotating shaft is connected to a micro servo motor 17, which is driven to rotate by an electrical signal sent by the control system, thereby adjusting the angle of the louvers within the range of 0°-90°. When the louvers are fully closed (0°), the fresh air inlet 14a is closed; the larger the louver angle, the larger the opening of the air inlet, and the greater the amount of fresh air intake.

[0118] In some possible embodiments, such as Figure 11 As shown, the air conditioner 1 may also include a blower fan 15, which is disposed in the air supply duct 100. The blower fan 15 is used to drive the air in the air supply duct 100 to blow into the indoor space through a plurality of second air outlets 130.

[0119] The air supply fan 15 uses mechanical power to force airflow, which counteracts the friction and local resistance of the air supply duct 100 (especially long or multi-bend ducts), ensuring that air can be delivered to various areas of the room over long distances and stably, avoiding air supply attenuation caused by natural convection or insufficient air pressure.

[0120] For example, such as Figure 11 As shown, the air supply fan 15 can be a cross-flow fan. During installation, first accurately mark the installation position on the inner wall of the indoor duct to ensure that the cross-flow fan is parallel to the duct axis. Then, use expansion bolts or snap-fit ​​to securely install the bracket 16 to the side wall of the duct. Align the cross-flow fan with the positioning groove of the bracket 16 and push it in. Use elastic retaining rings to fix the shaft and attach sound-insulating rubber strips at the contact points. Then, fix the DC brushless motor 17 to the cantilever frame and connect it coaxially with the fan shaft through an elastic coupling. Add an arc-shaped guide plate to the inner wall of the duct behind the bracket 16 to optimize airflow. Fill the joint between the bracket 16 and the duct with silicone sealant. Use magnetic sealing for the inspection port cover. Finally, connect the power cord of the motor 17 to the main control board and adjust the fan rotation, airflow, noise, and vibration parameters to ensure smooth operation and a flat appearance that does not affect the interior decoration effect.
