[0044] Currently, the air outlets of ducted air conditioners are usually hidden in the ceiling, and decorative light strips are installed on the ceiling. The airflow blown out of the air outlet of the ducted air conditioner will be blocked by the ceiling or decorative strips, which will affect the cooling and heating effect of the ducted air conditioner.

[0045] This disclosure provides a duct air conditioner, such as... Figures 1 to 12 As shown.

[0046] In some embodiments, the duct air conditioner includes a housing, an air outlet is provided on the side of the housing, and an air outlet frame is provided outside the air outlet. The duct air conditioner also includes a first air guide 10 and a second air guide 30. The first air guide 10 is rotatably disposed at the air outlet; the second air guide 30 is disposed on the air outlet frame and is used to open or completely close the air outlet. Under the drive of an external force, the first air guide 10 rotates axially to guide air, and the second air guide 30 first translates and extends out of the air outlet frame and then rotates to open upward or downward to guide air.

[0047] The ducted air conditioner provided in this embodiment includes a first air guide 10 and a second air guide 30. The first air guide 10 is rotatably disposed at the air outlet and can guide air left and right. The second air guide 30 is disposed on the air outlet frame to open or close the air outlet. Furthermore, the second air guide 30 can be extended out of the air outlet frame and rotated under the drive of an external force to open upward or downward for air guidance. In this way, the second air guide 30 is not restricted or interfered with by the air outlet frame during rotation, thus affecting its rotation angle. This allows for large-angle vertical air guidance, enabling the hot air blown from the ducted air conditioner to directly reach the ground for carpet-like air distribution, preventing users' feet from getting cold in winter. It also allows the cold air blown from the ducted air conditioner to rise and avoid directly blowing on users. Simultaneously, it improves the cooling or heating effect of the ducted air conditioner and enhances the user experience.

[0048] Optionally, the first air guide 10 includes multiple blades, each blade having a positioning shaft 11 at both ends. The positioning shaft 11 is fixed to the housing, and the blades rotate axially along the positioning shaft 11 to guide air left and right.

[0049] Understandably, each louver is positioned vertically at the air outlet to guide airflow left and right, such as... Figure 2 As shown. Each blade has a positioning shaft 11 at its upper and lower ends, and the positioning shafts 11 at the upper and lower ends of the blade are in a straight line. The upper and lower housings of the duct unit are respectively provided with holes and slots that match the positioning shafts 11, so as to fix the positioning shafts 11 of the blades and enable the blades to rotate around the positioning shafts 11.

[0050] Optionally, the duct unit also includes a first drive device 20, which is disposed inside the housing and connected to the side of the first air guide 10. The first drive device 20 is used to drive the swing blades to rotate along the positioning shaft 11.

[0051] like Figure 3 As shown, the first driving device 20 is disposed on one side of the first air guide 10 and is fixedly mounted on the mounting bracket. Optionally, there may be two first driving devices 20, which are respectively disposed at both ends of the first air guide 10. The first driving devices 20 at both ends of the first air guide 10 work synchronously and in coordination to make the rotation of the first air guide 10 stable.

[0052] Optionally, the first drive device 20 includes a motor, a handle 22, and a linkage rod 23. The motor is provided with an output shaft; the rotation shaft of the handle 22 is provided on the output shaft, and a protrusion 221 is provided at the free end of the handle 22; one end of the linkage rod 23 is provided with a mounting hole, and the protrusion 221 is slidably disposed in the mounting hole. The linkage rod 23 is connected to the swing blade in a transmission manner; the motor drives the handle 22 to rotate the linkage rod 23, and the linkage rod 23 drives the swing blade to rotate to guide the air left and right.

[0053] Optionally, a first motor 21 is fixed on the mounting bracket, which has a through hole through which the output shaft of the first motor 21 passes and is mounted on the rotation shaft of the handle 22. Optionally, the first motor 21 is located at the lower part of the mounting bracket, and the handle 22 is located at the upper part of the mounting bracket. Understandably, the rotation shaft of the handle 22 is located in the vertical direction, and the protrusion 221 is set perpendicular to the handle 22 and is also set in the vertical direction. This facilitates the motor driving the handle 22 to rotate the linkage rod 23.

[0054] Optionally, multiple mounting holes are evenly arranged on the linkage rod 23, and a rotating shaft 12 is provided next to the fixed shaft at the upper end of each swing blade. The rotating shaft 12 corresponds to the mounting hole one by one, and the rotating shaft 12 is slidably disposed in the mounting hole.

[0055] In this embodiment, the transmission connection between the linkage 23 and the pendulum is achieved through the cooperation of the rotating shaft 12 and the mounting hole. Optionally, the center of the mounting hole is a circular hole, and elongated holes are connected to both sides of the circular hole. The circular hole is used to install and adapt to the rotating shaft 12 of the linkage 23. This allows for sufficient slack for the rotation of the pendulum and prevents the linkage 23 from interfering with the rotation of the pendulum during rotation.

[0056] Optionally, the rotation angle of the handle 22 can be 180°, allowing the duct air conditioner to swing left and right within a 180° range via a first drive device 20. To accommodate the rotation angle of the handle 22, multiple arc-shaped clearance areas 231 are evenly provided on the linkage rod 23. The fixed shaft at the upper or lower end of each swing blade is located within the clearance area 231, and the fixed shaft at the upper or lower end of the swing blade corresponds one-to-one with the clearance area 231.

[0057] Optionally, the effective length of rotation of the handle 22 is equal to the straight-line distance between the positioning shaft 11 and the rotation shaft 12 on the oscillating blade. This allows the fixed shaft at the upper or lower end of the oscillating blade to move from its initial clearance area 231 into an adjacent clearance area 231 when the handle 22 rotates 180° from its initial position, saving space inside the duct unit occupied by the linkage 23. For example, Figure 3 This is a schematic diagram of the initial position of the swing blade. When the handle 22 rotates 180°, the positioning shaft 11 at the upper or lower end of the swing blade will enter the adjacent right-side clearance area 231 on the linkage rod 23.

[0058] Optionally, the duct unit also includes a second drive device 40, which is disposed inside the housing. An extension 100 is provided on the air outlet frame. The second drive device 40 extends out of the extension 100 and is movably connected to the second air guide 30. The second drive device 40 is used to drive the second air guide 30 to extend and rotate.

[0059] In this embodiment of the present disclosure, the second driving device 40 can drive the second air guide 30 to extend horizontally out of the air outlet frame before rotating. In this way, the second air guide 30 can guide air at a large angle, and it will not be disturbed by the air outlet frame during rotation. At the same time, it improves the cooling or heating effect of the duct air conditioner.

[0060] Optionally, the second air guide 30 is an air guide plate, which is disposed on the air outlet frame. When the air guide plate is closed, it can completely seal the air outlet in the air outlet frame.

[0061] Optionally, there are two second drive devices 40, respectively disposed at both ends of the second air guide 30. This embodiment of the present disclosure is oriented towards... Figure 1 The structure of the second drive unit 40 at the right end of the duct machine shown is explained using this example.

[0062] Optionally, the second driving device 40 includes a first connecting rod 42, a second connecting rod 43 and a track plate 44. One end of the first connecting rod 42 is rotatably connected to the second air guiding member 30, and a first limiting portion is provided on one side surface of the first connecting rod 42; one end of the second connecting rod 43 is rotatably connected to the second air guiding member 30, and a second limiting portion is provided on one side surface of the second connecting rod 43; the track plate 44 is fixed in the housing, and the track plate 44 is provided with a first track in a shape of a Chinese character 'ren' (human) and a second linear track. The first limiting portion is slidably disposed on the first track and the second track, and the second limiting portion is slidably disposed on the second track; wherein, the first connecting rod 42 cooperates with the second connecting rod 43 under the drive of an external force to drive the second air guiding member 30 to translate out of the air conditioner and then rotate.

[0063] In the embodiment of the present disclosure, the movement track of the second air guiding member 30 is: the second air guiding member 30 first translates out of the air conditioner and then rotates. Among them, the rotation can be understood as rotating while extending, so that the movement stroke of the second air guiding member 30 can be shortened, and the time for the second air guiding member 30 to be opened to a preset angle can be accelerated.

[0064] Optionally, the first track includes a first linear track 441 and a bifurcated track. The end of the first linear track 441 is connected to the starting end of the bifurcated track. Among them, the bifurcated track includes a first branch track 442 and a second branch track 443. The first branch track 442 extends in one direction, and the second branch track 443 intersects with the first branch track 442 and extends in another direction. That is, the two branch tracks are like the left and right strokes of the Chinese character 'ren' (human) and extend in different directions. The structure of the first track in the shape of a Chinese character 'ren' is as Figure 11 shown.

[0065] Optionally, both the first branch track 442 and the second branch track 443 have a certain curvature and are convex outward. In this way, it can be ensured that the second air guiding member 30 can rotate at a uniform speed after extending out of the air outlet frame, avoiding the situation of quickly rotating upward or quickly rotating downward, improving the accuracy of the movement track control of the second driving device 40 for the second driving member, and also improving the user experience.

[0066] In the embodiment of the present disclosure, the first linear track 441 is arranged in the horizontal direction. That the first branch track 442 is convex outward means that the center of the arc where the first branch track 442 is located is above the first branch track 442, rather than below the first branch track 442. Similarly, that the second branch track 443 is convex outward means that the center of the arc where the second branch track 443 is located is below the second branch track 443, rather than above the second branch track 443. Among them, 'above' or 'below' is based on the Figure 11 orientation of the track plate 44 shown.

[0067] Optionally, the second track is arranged in a straight line along the horizontal direction. The first limiting part is slidably disposed within the first track and the second track, and the second limiting part is slidably disposed within the second track. It can be understood that the first track and the second track together define the movement trajectory of the first link 42, and the second track is used to define the movement trajectory of the second link 43.

[0068] Optionally, the second track includes a second linear track 444, a third linear track 445, and a fourth linear track 446. The second linear track 444 is positioned between the first and second bifurcated tracks, the third linear track 445 is positioned above the second linear track 444, and the fourth linear track 446 is positioned below the second linear track 444. In this way, multiple linear tracks can more stably constrain the linear motion of the second connecting rod 43.

[0069] Understandably, the directions of the first linear track 441 and the second track are the same as the direction in which the second air guide 30 extends out of the air outlet frame. In this way, the first connecting rod 42 moves along the first linear track 441, and the second connecting rod 43 moves along the second track. The first connecting rod 42 and the second connecting rod 43 can synchronously drive the second air guide 30 to first extend out of the air outlet frame in a horizontal direction, and then rotate at a constant speed.

[0070] Optionally, the first limiting part includes at least two sliding posts. Optionally, the two sliding posts are slidably disposed on the first track and the second track, respectively.

[0071] Optionally, the first limiting part includes a first sliding post 424 and a second sliding post 425. The first sliding post 424 is disposed at the top of the first connecting rod 42, and the second sliding post 425 is disposed at the middle of the first connecting rod 42. The first sliding post 424 is slidably disposed within the first track, and the second sliding post 425 is slidably disposed within a portion of the straight track of the second track. When the first sliding post 424 moves from the first straight track 441 to the first branch track 442 or the second branch track 443, the second connecting rod 43 continues to move linearly along the second track. The first connecting rod 42 and the second connecting rod 43 generate relative motion, and the first connecting rod 42 changes direction, thereby cooperating with the second connecting rod 43 to drive the second air guide 30 to rotate at a uniform speed.

[0072] Optionally, the second limiting part includes at least two sliding posts, each of which is disposed within a straight track of the second track.

[0073] Optionally, the second limiting part includes a third sliding post 431 and a fourth sliding post 432, wherein the third sliding post 431 is slidably disposed within the third linear track 445, and the fourth sliding post 432 is slidably disposed within the fourth linear track 446. This improves the stability of the second connecting rod 43 moving within the second track.

[0074] Optionally, there are two third sliding posts 431, which are horizontally slidably disposed within the third linear track 445. Similarly, there are also two fourth sliding posts 432, which are horizontally disposed within the fourth linear track 446. The arrangement of the four sliding posts is as follows. Figure 10 As shown.

[0075] During movement, the second air guide 30 may rotate vertically due to its own gravity, affecting its trajectory and preventing it from following the preset path. By setting four sliding posts on the back of the second link 43, the second link 43 can be stably limited in the horizontal direction, thus preventing the second air guide 30 from rotating horizontally.

[0076] Optionally, the second link 43 is also provided with a through slide 433 that penetrates the surface of the second link 43 plate. In this way, the second sliding column 425 of the first link 42 can pass through the through slide 433 and move along the second track.

[0077] Optionally, a limit mechanism is provided between the first link 42 and the second link 43 to prevent the second link 43 from swaying during the movement of the second air guide 30.

[0078] Optionally, the limiting mechanism includes a limiting post 434 and a V-groove 422. The limiting post 434 is disposed on the second connecting rod 43; the V-groove 422 is disposed on the first connecting rod 42, and the limiting post 434 is slidably disposed in the V-groove 422.

[0079] In this embodiment, the limiting post 434 is disposed at the top end of the second connecting rod 43. The end of the second connecting rod 43 is connected to the second air guide 30. In this way, both ends of the second connecting rod 43 are limited, thereby limiting the position of the second connecting rod 43. No matter where the second air guide 30 moves, the limiting post 434 is always within the V-groove 422, and the user cannot manually move the second connecting rod 43, thus improving the reliability of the second connecting rod 43.

[0080] Optionally, the V-groove 422 includes a first positioning groove 4221 and a second positioning groove 4222 that meet. Both the first positioning groove 4221 and the second positioning groove 4222 are straight, and they have the same starting end and ends extending in different directions, such as... Figure 8 As shown. When the second air guide 30 is closed, the limiting post 434 is located at the junction of the first positioning groove 4221 and the second positioning groove 4222; during the process of the second air guide 30 opening upward from the closed state, the limiting post 434 slides from the junction towards the end of the first positioning groove 4221; during the process of the second air guide 30 opening downward from the closed state, the limiting post 434 slides from the junction towards the end of the second positioning groove 4222.

[0081] Optionally, both the first link 42 and the second link 43 are rotatably connected to the second air guide 30. Optionally, one end of the first link 42 is provided with a first connecting hole 426, and one end of the second link 43 is provided with a second connecting hole 435.

[0082] Optionally, a connector is provided between the first link 42 and the second link 43 and the mounting base 31 of the second air guide 30. The connector is hinged to the first connecting hole 426 and the second connecting hole 435 respectively, and the connector is snapped into the mounting base 31. This facilitates the assembly and disassembly of the second air guide 30 and improves the assembly efficiency of the second air guide 30.

[0083] Optionally, the second drive device 40 further includes a crank 41, the free end of which is provided with a first drive shaft 411; the first connecting rod 42 is provided with a through groove 421, and the first drive shaft 411 is slidably disposed in the through groove 421 to drive the first connecting rod 42 to move.

[0084] Optionally, crank 41 is driven to connect with a second motor. The drive shaft of the second motor is located at the rotation shaft 12 of crank 41. The second motor provides driving force for the rotation of crank 41, thereby enabling crank 41 to slide to connect with the first connecting rod 42 and drive the first connecting rod 42 to move.

[0085] Optionally, the crank 41 includes a rotating disk and a rotating rod, with a first transmission shaft 411 disposed at the free end of the rotating rod. Optionally, a reinforcing rib 413 is also provided at the connection between the rotating rod and the rotating disk of the crank 41 to prevent twisting or breakage between the rotating rod and the rotating disk during the rotation of the crank 41. Optionally, there may be multiple reinforcing ribs 413. Figure 12 As shown, the crank 41 is provided with two reinforcing ribs 413.

[0086] Optionally, the through groove 421 is straight, and the first drive shaft 411 slides in the through groove 421 to provide driving force for the movement of the second air guide 30.

[0087] Optionally, the crank 41 further includes a second drive shaft 412, which is disposed between the rotating shaft 12 of the crank 41 and the first drive shaft 411. The first connecting rod 42 is also provided with a limiting groove 423. The second drive shaft 412 is slidably disposed in the limiting groove 423 so that the first connecting rod 42 moves and turns, thereby cooperating with the second connecting rod 43 to drive the second air guide 30 to rotate at a uniform speed.

[0088] Optionally, the first linear track 441 includes a straight section and a transition section, the transition section connecting to the branch track. If the first linear track 441 does not have a transition section, the rotational speed of the second air guide 30 will suddenly increase after it extends out of the air outlet frame. The transition section prevents the second air guide 30 from suddenly accelerating after extending out of the air outlet frame. The transition section is... Figure 11 The dashed line indicates the portion of the straight track.

[0089] During the movement of the second air guide 30, when the first sliding column 424 of the first connecting rod 42 moves to the transition section, the transition section has no track constraint on the first sliding column 424. Therefore, due to gravity, the first connecting rod 42 may not move along the preset first branch track 442 or the second branch track 443. Thus, a limiting groove 423 can be provided on the first connecting rod 42. The abutting force generated between the second drive shaft 412 and the limiting groove 423 provides the first sliding column 424 of the first connecting rod 42 with the driving force to select between the first branch track 442 and the second branch track 443.

[0090] Optionally, the limiting groove 423 is disposed below the through groove 421 and communicates with the through groove 421. In this way, during the process of the first drive shaft 411 driving the first connecting rod 42 to move, the second drive shaft 412 can slide from the limiting groove 423 through the through groove 421 to the top of the through groove 421 without interfering with the movement of the first connecting rod 42.

[0091] Optionally, a first limiting section and a second limiting section are respectively provided at the two ends of the inner edge of the limiting groove 423 and the connection point of the through groove 421. Both the first limiting section and the second limiting section are arc-shaped so that the first connecting rod 42 can smoothly slide from the end of the straight section of the first straight track 441 into the beginning of the first branch track 442 or the second branch track 443, so as to avoid the impact of the first connecting rod 42 on the first track of the track plate 44, which would cause the second air guide 30 to be stuck.

[0092] Optionally, the inner edge of the limiting groove 423 includes a first flared section 4231, a U-shaped section, and a second flared section 4232 connected in sequence; wherein, the first limiting section is disposed on the first flared section 4231, and the second drive shaft 412 slides along the first limiting section so that the first connecting rod 42 smoothly slides into the starting end of the first branch track 442; the second limiting end is disposed on the second flared section 4232, and the second drive shaft 412 slides along the second limiting section so that the first connecting rod 42 smoothly slides into the starting end of the second branch track 443.

[0093] Optionally, the first link 42 is provided with multiple rollers 427 to reduce the friction between the first link 42 and adjacent components during the movement, making the movement of the first link 42 smoother, reducing the wear of the first link 42, and extending the service life of the first link 42.

[0094] Optionally, the ducted air conditioner includes an upward blowing mode and a downward blowing mode; in the upward blowing mode, the second air guide 30 blows air upward at an angle, and the opening angle of the second air guide 30 is greater than or equal to 80°; in the downward blowing mode, the second air guide 30 blows air downward at an angle, and the opening angle of the second air guide 30 is greater than or equal to 60°.

[0095] Understandably, in either the top-blowing or bottom-blowing mode of the ducted air conditioner, the first air guide component 10 is in the air guiding state, meaning the oscillating blades are not located... Figure 2 The initial position shown is not the starting position, but the air can be directed at any angle between the initial position and 180°.

[0096] Optionally, the upward blowing mode is a cooling mode. The cold air blown out from the duct unit can be guided in an approximately horizontal direction along the second air guide 30. The cold air will not blow directly on the user, but will blow towards the top of the room, thereby enabling faster heat exchange with the hot air in the room and improving the cooling effect of the duct unit.

[0097] Optionally, the down-blowing mode is the heating mode. The hot air blown out from the duct unit can be blown along the second air guide 30 to the floor of the room for carpet-like air distribution. This can avoid the problem of cold feet for users in winter. At the same time, it can also accelerate the heat exchange with the cold air in the room and improve the heating effect of the duct unit.
