[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0031] The embodiment of the present application provides a ducted air conditioner to solve the problem of insufficient return air space caused by manual installation of the ducted air conditioner.

[0032] In the embodiments of this application, Figure 1 and Figure 2 As shown, the ducted air conditioner includes a main body 1, an air inlet duct 2 and an air guide structure 3. The air inlet duct 2 has an air inlet 21 and an air outlet 22 that are arranged opposite to each other and connected. The air inlet 21 is opened downward, and the air outlet 22 is opened on the peripheral wall of the air inlet duct 2 and connected to the main body 1.

[0033] The air guide structure 3 is arranged in the air inlet pipe 2 and is located between the air inlet 21 and the air outlet 22. The air guide structure 3 is used to guide the air flow from the air inlet 21 toward the air outlet 22. The air guide structure 3 can flexibly change the air guide angle of the air guide structure 3.

[0034] It should be noted that the air guide structure 3 refers to a structure capable of redirecting airflow, thereby directing airflow from the downward-facing air inlet 21 to the air outlet 22 located on the peripheral wall of the air inlet duct 2. The peripheral wall of the air inlet duct 2 refers to the four sides of the air inlet duct 2, excluding the upper and lower side walls. The air inlet duct 2 can be connected to the air inlet duct 2 via the rear side of the main body 1, where the rear side is relative to the side of the main body 1 facing the user. The air guide angle refers to the angle between the air guide structure 3 and the air inlet duct 21 and the air outlet 22. The air guide structure 3 is said to be movable, meaning that the air guide structure 3 and the air inlet duct 2 are connected in an adjustable manner. This adjustable connection can be a rotating connection, a sliding connection, or a detachable connection. A detachable connection between the air guide structure 3 and the air inlet duct 2 refers to the air inlet duct 2 being provided with multiple structures for detachable connection with the air guide structure 3. This detachable connection can be achieved through common methods such as snap-fit ​​connections and bolt connections.

[0035] It is understood that by positioning the air inlet 21 downward to avoid the wall, the size of the return air space is no longer affected by the installation distance between the duct unit and the wall. Return air can enter the air inlet duct 2 directly from the bottom of the duct unit through the air inlet 21. Furthermore, during the design phase, the size of the air inlet 21 and the air inlet duct 2 can be adaptively adjusted based on the performance of the main body 1 to increase or decrease the amount of air entering the main body 1 through the air inlet duct 2. Furthermore, because the air inlet 21 and the air outlet 22 are located in different directions, the airflow direction from the air inlet duct 2 can be changed by the air guide structure 3, allowing the airflow to enter the main body 1 quickly and smoothly. For example, the airflow direction can be changed by designing air guides 33 of different shapes on the air guide structure 3, such as an arc. The airflow direction can also be changed by using a movable air guide structure 3. By optimizing the airflow direction, the noise generated when the air flows through the air inlet duct 2 is reduced.

[0036] In some embodiments, as Figure 3 As shown, the air guide structure 3 is provided with an air guide port 33; the side wall of the air guide port 33 facing the air inlet 21 and the air outlet 22 is an air guide surface 311;

[0037] The angle between the wind guide surface 311 and the air inlet 21 is an acute angle or a right angle, and the angle between the wind guide surface 311 and the air outlet 22 is an acute angle or a right angle; the wind guide angle is the angle between the wind guide surface 311 and the air inlet 21, or the angle between the wind guide surface 311 and the air outlet 22.

[0038] In some embodiments, the air guide structure 3 is provided with an air guide outlet 33; the side wall of the air guide outlet 33 facing the air inlet 21 or the air outlet 22 is an air guide surface 311; the angle between the air guide surface 311 and the air inlet 21 is an acute angle or a right angle, and the angle between the air guide surface 311 and the air outlet 22 is an acute angle or a right angle; the air guide angle is the angle between the air guide surface 311 and the air inlet 21, or the angle between the air guide surface 311 and the air outlet 22.

[0039] It is understood that when the air guide surface 311 faces both the air inlet 21 and the air outlet 22 and forms an angle with them, the airflow flowing in from the air inlet 21 is reflected on the air guide surface 311, thereby changing its direction and flowing toward the air outlet 22. When the air guide structure 3 is movable, due to the change in the position of the air guide surface 311, for example, when the air guide structure 3 moves to be parallel to the end surface of the air inlet 21, the air guide surface 311 still forms an angle with the air inlet 21 and the air outlet 22, thereby ensuring effective air guidance in different situations.

[0040] In some embodiments, as Figure 3 As shown, one end of the air guide structure 3 is rotatably connected to the air inlet pipe 2, and the other end of the air guide structure 3 can be detachably connected to different positions of the air inlet pipe 2 to change the angle of the air guide surface 311 relative to the air inlet 21 and the air outlet 22.

[0041] It should be noted that the detachable connection can be achieved using common methods such as a snap connection, a bolt connection, etc. It is understandable that the movement of the air guide structure 3 is achieved through the detachable connection at the other end of the air guide structure 3. It is conceivable that the connection method at both ends of the air guide structure 3 allows the air guide structure 3 to move in a swinging manner, so that the air guide angle of the air guide structure 3 can be changed by changing the swing angle of the air guide structure 3.

[0042] In some embodiments, as Figure 3As shown, the air guide structure 3 is provided with a first plug-in portion 34 and a second plug-in portion 35. The first plug-in portion 34 is rotatably connected to the side wall of the air inlet pipe 2 near the air outlet 22. The air inlet pipe 2 is provided with multiple mounting holes 23. The air guide structure 3 rotates to switch the second plug-in portion 35 between the multiple mounting holes 23, and the second plug-in portion 35 is plugged into any mounting hole 23 to change the air guide angle of the air guide structure 3.

[0043] It should be noted that when the second plug portion 35 is inserted into or removed from the mounting hole 23, the deformation of the air guide structure 3 is required to complete the plugging and unplugging of the second plug portion 35. It is understandable that the above method can improve the convenience of operating the air guide structure 3.

[0044] In some embodiments, as Figure 3 As shown, a connecting hole 24 is provided on the side wall of the air inlet pipe 2 near the air outlet 22, and the first plug-in portion 34 can be rotatably inserted into the connecting hole 24. The insertion depth of the first plug-in portion 34 in the connecting hole 24 is greater than the insertion depth of the second plug-in portion 35 in the mounting hole 23.

[0045] It should be noted that the insertion depth refers to the length, along the axial direction of the mounting hole 23, of the first plug-in portion 34 and the second plug-in portion 35 within the corresponding mounting hole 23 and connecting hole 24. It is understood that the insertion depth of the first plug-in portion 34 is greater than the insertion depth of the second plug-in portion 35. This can prevent the first plug-in portion 34 from being removed from the connecting hole 24 when the second plug-in portion 35 is inserted or removed, thereby ensuring that the air guide structure 3 is stably installed within the air inlet duct 2.

[0046] For example, the insertion depth of the first plug portion 34 can be as follows: the end of the first plug portion 34 away from the air guide structure 3 is located within the connection hole 24, the insertion depth of the first plug portion 34 is equal to the hole depth of the connection hole 24, and the first plug portion 34 extends through the connection hole 24. Accordingly, the second plug portion 35 preferably adopts a form in which the end of the second plug portion 35 away from the air guide structure 3 is located within the mounting hole 23.

[0047] In some embodiments, as Figure 3 As shown, the second plug-in portion 35 narrows along the direction in which the second plug-in portion 35 is inserted into the mounting hole 23. It should be noted that the narrowing of the second plug-in portion 35 refers to a reduction in its maximum outer diameter. It is understood that by reducing the size of the portion of the second plug-in portion 35 that is inserted into the mounting hole 23, the insertion and removal of the second plug-in portion 35 is made easier, facilitating easier operation of the second plug-in portion 35 between multiple mounting holes 23. For example, the second plug-in portion 35 can be reduced in size by reducing its diameter or by providing a transition surface.

[0048] In some embodiments, as Figure 4 and Figure 5 As shown, the second plug-in portion 35 is provided with a step surface 351, and the step surface 351 faces the inner wall of the mounting hole 23. In this way, the step surface 351 can move in and out of the mounting hole 23 more smoothly.

[0049] In some embodiments, as Figure 3 As shown, the air guide structure 3 includes a plurality of air guide blades 31, which are spaced apart along a first direction to form a plurality of air guide ports 33. The first direction is the direction from the first plug-in portion 34 to the second plug-in portion 35. It is understood that when the air guide structure 3 is movable, the position of the air guide ports 33 can be more effectively adjusted.

[0050] In some embodiments, as Figure 4 As shown, the air guide structure 3 also includes connecting ribs 32 connected to multiple air guide blades 31. Multiple connecting ribs 32 are arranged at intervals along the second direction. The second direction is the plug-in direction of the second plug-in portion 35. There is an angle between the first direction and the second direction. The distance between adjacent connecting ribs 32 is greater than the distance between adjacent air guide blades 31.

[0051] It should be noted that the plugging direction of the second plug-in portion 35 refers to the axial direction of the mounting hole 23. For example, the angle between the first direction and the second direction can be a right angle or a 60° angle.

[0052] It can be understood that the connecting ribs 32 mainly serve to improve the stability of the air guide structure 3, and further reduce the deformation resistance of the air guide structure 3 along the plug-in direction of the second plug-in part 35 by designing the distance between adjacent connecting ribs 32 and adjacent air guide blades 31, so that the air guide blades 31 have a larger deformation amount, which is convenient for plugging and unplugging the second plug-in part 35.

[0053] In some embodiments, as Figure 5 As shown, the second plug-in portion 35 is provided with two step surfaces 351 , and the two step surfaces 351 are located in a direction perpendicular to the first direction and the second direction. In this way, the step surfaces 351 better correspond to the moving direction of the second plug-in portion 35 .

[0054] In some embodiments, the air guide surface 311 is a plane. It is understood that when the air guide surface 311 is a plane, the air guide structure 3 is controlled to rotate to a position where an angle exists between the air guide surface 311 and both the air inlet 21 and the air outlet 22. In this way, the airflow is reflected on the plane air guide surface 311, thereby changing the direction of the airflow flowing in from the air inlet 21.

[0055] In some embodiments, as Figure 7 and Figure 8As shown, the air guide surface 311 is a curved surface. It should be noted that the curved surface can be a convex surface along the direction from the second plug-in portion 35 to the first plug-in portion 34, or a convex surface along the direction from the first plug-in portion 34 to the second plug-in portion 35. It is understood that by providing the air guide surface 311 with a curved surface structure, the number of airflow reflections on the air guide surface 311 is increased, thereby better guiding the airflow.

[0056] In some embodiments, as Figure 9 As shown, the side of the air guide blade 31 that faces away from the air guide surface 311 is a curved surface or a folded surface. It should be noted that the curvature direction of the side of the air guide blade 31 that faces away from the air guide surface 311 can be the same as or different from that of the air guide surface 311; for example, when the air guide surface 311 protrudes in the direction from the second plug-in portion 35 to the first plug-in portion 34, the curvature direction of the side of the air guide blade 31 that faces away from the air guide surface 311 is opposite to that of the air guide surface 311. It can be seen that the cross-sectional shape of the air guide blade 31 is a shuttle shape, as shown in FIG. Figure 8 When the wind guide surface 311 protrudes along the direction of the first plug portion 34 pointing to the second plug portion 35, the bending direction of the side of the wind guide blade 31 away from the wind guide surface 311 is the same as the wind guide surface 311. It can be seen that the cross-sectional shape of the wind guide blade 31 is an arc, such as Figure 7 As shown. A folded surface refers to a surface formed by connecting multiple planes with an angle; for example, when the wind guide surface 311 protrudes from the first plug-in portion 34 to the second plug-in portion 35, the side of the wind guide blade 31 facing away from the wind guide surface 311 includes two planes, the angle between the two planes is 90 degrees, and the angle is toward the first plug-in portion 34, as shown. Figure 9 Such a structure can provide better support for the wind guide surface 311 and improve the stability of the wind guide blade 31. In general, the structure of the wind guide blade 31 can reduce the noise during the wind guiding process.

[0057] In some embodiments, as Figure 7 As shown, the air inlet duct 2 is provided with an arc-shaped guide surface, which connects the air inlet 21 and the air outlet 22 and is used to guide the air flow from the air inlet 21 to the air outlet 22. It is understood that the arc-shaped guide surface can change the direction of the air flow to guide the air flow to the air outlet 22, speed up the return air speed, and reduce noise.

[0058] In some embodiments, as Figure 7 As shown, when the second plug-in portion 35 is plugged into one of the mounting holes 23, the angle between the air guide blade 31 and the horizontal direction is 45° to 60°. It should be noted that the mounting hole 23 here can be the mounting hole 23 when the air guide structure 3 is movable to the extreme position, or it can be the mounting hole 23 located between the two extreme positions.

[0059] In some embodiments, the air inlet duct 2 is detachably connected to the rear side of the main body 1. The detachable connection method can be screw connection.
