[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0041] Combination Figure 1 As shown, the embodiment of the present disclosure provides a duct unit, comprising: a housing 100, a first sliding member 200 and a second sliding member 300. The first sliding member 200 is connected to the side wall of the housing 100; the second sliding member 300 is slidably connected to the first sliding member 200; wherein, when the duct unit is installed indoors for use, the duct unit is embedded between the wall and the ceiling, and the second sliding member 300 is installed on the side wall of the wall and / or the inner wall of the ceiling, so that the housing 100 can slide out or retract between the wall and the ceiling under the cooperation of the first sliding member 200 and the second sliding member 300.

[0042] When the duct unit provided by the embodiment of the present disclosure is installed indoors, the duct unit is embedded between the wall and the ceiling. The housing 100 can slide out from between the wall and the ceiling with the cooperation of the first sliding member 200 and the second sliding member 300, so that the housing 100 is exposed outside the ceiling, and the duct unit can be inspected and maintained outside the ceiling. There is no need to disassemble the ceiling, the operation is relatively simple, and the inspection efficiency of the duct unit can be improved, which improves the user experience.

[0043] It can be understood that the second sliding member 300 is installed on the side wall of the wall and / or the inner wall of the ceiling. It is necessary to determine whether the second sliding member 300 is installed on the wall, or on the inner wall of the ceiling, or part of the second sliding member 300 is installed on the wall and the other part is installed on the wall based on the actual installation situation in the room.

[0044] Exemplarily, the duct machine can also be installed in a wall hole of a wall, or used in a cabinet. At the same time, the housing 100 can also slide under the cooperation of the first sliding member 200 and the second sliding member 300, so that the housing 100 slides into the wall hole or the cabinet.

[0045] Combination Figure 1As shown, optionally, the first sliding member 200 includes: a first slide rail 210. Two first slide rails 210 are provided, which are respectively connected to two opposite side walls of the casing 100. In this way, the two first slide rails 210 are connected to the two opposite side walls of the casing 100, and the span of the connection is relatively large. With the cooperation of the first slide rail 210 and the second sliding member 300, the casing 100 slides out or retracts between the wall and the ceiling, and the sliding stability is relatively high. In the case that the casing 100 slides out between the wall and the ceiling, the casing 100 is exposed on the outside of the ceiling, and then the duct machine is inspected and maintained on the outside of the ceiling. There is no need to disassemble the ceiling, the operation is relatively simple, and the inspection efficiency of the duct machine can be improved, which improves the user experience.

[0046] Specifically, the two first slide rails 210 are respectively connected to the top ends of the two opposite side walls of the housing 100. In this way, when the top ends of the two opposite side walls of the housing 100 are respectively connected to the two first slide rails 210, the center of the housing 100 is relatively low, thereby improving the stability of the connection between the housing 100 and the first slide rails 210. With the cooperation of the first slide rails 210 and the second sliding member 300, the sliding stability of the housing 100 when sliding out or retracting between the wall and the ceiling is further improved.

[0047] Optionally, the second sliding member 300 includes: a second slide rail 310. Two second slide rails 310 are provided, and each first slide rail 210 is slidably connected to a second slide rail 310. In this way, one first slide rail 210 is slidably connected to one second slide rail 310, and under the cooperation of the first slide rail 210 and the second slide rail 310, the casing 100 slides out or retracts between the wall and the ceiling, and the sliding stability is relatively high. In the case that the casing 100 slides out between the wall and the ceiling, the casing 100 is exposed outside the ceiling, and then the duct machine is inspected and maintained outside the ceiling. There is no need to disassemble the ceiling, the operation is relatively simple, and the inspection efficiency of the duct machine can be improved, which improves the user experience.

[0048] Specifically, each second slide rail 310 is located below and slidably connected to a corresponding first slide rail 210. In this way, the second slide rail 310 is located below the first slide rail 210, and the second slide rail 310 provides upward support for the first slide rail 210, and the support stability is relatively high, reducing the risk of the first slide rail 210 and the second slide rail 310 being separated.

[0049] Optionally, the second sliding member 300 further includes: a slide rail bracket 320. A slide rail bracket 320 is provided on each second slide rail 310 and is fixedly connected thereto; wherein, when the air duct unit is installed indoors for use, the slide rail bracket 320 is fixedly connected to the side wall of the wall and / or the inner wall of the ceiling. In this way, the second slide rail 310 is fixedly connected to the side wall of the wall and / or the inner wall of the ceiling through the slide rail bracket 320, and the contact connection between the slide rail bracket 320 and the side wall of the wall and / or the inner wall of the ceiling is greater, and the connection stability is higher. At the same time, the load-bearing weight of the second slide rail 310 is increased, and the risk of the second slide rail 310 falling is reduced.

[0050] Optionally, each second slide rail 310 is provided with a plurality of slide rail brackets 320. In this way, a second slide rail 310 is fixedly connected to the side wall of the wall and / or the inner wall of the ceiling through the plurality of slide rail brackets 320, and the plurality of slide rail brackets 320 have a greater contact connection with the side wall of the wall and / or the inner wall of the ceiling, further improving the connection stability. At the same time, the load-bearing capacity of the second slide rail 310 is increased, reducing the risk of the second slide rail 310 falling.

[0051] Specifically, two slide rail brackets 320 are provided on each second slide rail 310. In this way, one second slide rail 310 is fixedly connected to the side wall of the wall and / or the inner wall of the ceiling through the two slide rail brackets 320, and the two slide rail brackets 320 have a greater contact connection with the side wall of the wall and / or the inner wall of the ceiling, further improving the connection stability. At the same time, the load-bearing weight of the second slide rail 310 is increased, reducing the risk of the second slide rail 310 falling.

[0052] Optionally, the housing 100 is detachably connected to the first sliding member 200. In this way, the housing 100 can be removed from the first sliding member 200. After the housing 100 is removed, it can be placed on the ground, which makes maintenance more convenient. In addition, the housing 100 slides out from between the wall and the ceiling with the cooperation of the first sliding member 200 and the second sliding member 300, and then the housing 100 is removed from the first sliding member 200 more conveniently. It also avoids the disassembly of the ceiling, reducing the risk of the housing 100 colliding with the ceiling.

[0053] Combination Figure 3As shown, optionally, the housing 100 is provided with a disassembly hole 101; the first sliding member 200 is provided with a clamping piece 220, and there is a clamping interval between the clamping piece 220 and the first sliding member 200; wherein, when the housing 100 and the first sliding member 200 are installed together, the clamping piece 220 passes through the disassembly hole 101, and the edge of the disassembly hole 101 is clamped in the clamping interval. In this way, the clamping piece 220 passes through the disassembly hole 101, and then the first sliding member 200 and the clamping piece 220 are moved relative to the housing 100 so that the edge of the disassembly hole 101 is clamped in the clamping interval, so that the housing 100 and the first sliding member 200 are detachably installed together. Conversely, the housing 100 and the first sliding member 200 can be separated, so as to achieve rapid disassembly of the housing 100 and the first sliding member 200. After the housing 100 is removed from the first sliding member 200 and placed on the ground, it is more convenient to inspect and maintain.

[0054] Optionally, along the horizontal direction, the length of the clamping piece 220 is less than or equal to the length of the disassembly hole 101. In this way, when the length of the clamping piece 220 is equal to the length of the disassembly hole 101, and when the length of the clamping piece 220 is less than the length of the disassembly hole 101, the clamping piece 220 can pass through the disassembly hole 101 relatively smoothly.

[0055] Optionally, a clamping piece 220 is provided on the upper side wall of each first slide rail 210, and a clamping gap is formed between each clamping piece 220 and the corresponding first slide rail 210. In this way, each first slide rail 210 is detachably connected to the housing 100 through the corresponding clamping piece 220 and the clamping gap, thereby increasing the speed of removing the housing 100 from the first slide rail 210.

[0056] Optionally, buckle plates 110 are provided on two opposite side walls of the housing 100, and each buckle plate 110 is fixedly connected to the housing 100. When the housing 100 is connected to the two first slide rails 210, each buckle plate 110 is buckled on a corresponding first slide rail 210. In this way, each buckle plate 110 is buckled on a corresponding first slide rail 210, and the first slide rail 210 provides support for the buckle plate 110. The contact area between the buckle plate 110 and the first slide rail 210 is relatively large, and the support stability is relatively high.

[0057] Specifically, each buckle plate 110 is provided with a disassembly hole 101 .

[0058] Combination Figure 4As shown, optionally, the duct air conditioner further includes: a cover plate 400. The cover plate 400 is arranged on one side of the casing 100. When the duct air conditioner is installed indoors for use, the cover plate 400 is movably covered on the opening between the wall and the ceiling. In this way, the cover plate 400 is movably covered on the opening between the wall and the ceiling, and the cover plate 400 blocks the casing 100 to prevent the casing 100 from being directly exposed. The cover plate 400 can be movably opened at the opening to expose the opening, so that the casing 100 can slide out or retract between the wall and the ceiling under the cooperation of the first sliding member 200 and the second sliding member 300, which is convenient for maintenance.

[0059] Combination Figure 5 As shown, optionally, a rotating shaft 401 is provided on the upper end of the cover plate 400, and the rotating shaft 401 is rotatably connected to the connecting seat 402. When the duct unit is installed indoors for use, the connecting seat 402 is installed on the wall. In this way, the cover plate 400 rotates on the connecting seat 402 through the rotating shaft 401, so that the opening is exposed, which facilitates the housing 100 to slide out or retract between the wall and the ceiling under the cooperation of the first sliding member 200 and the second sliding member 300, and is convenient for maintenance. The cover plate 400 can also rotate on the connecting seat 402 through the rotating shaft 401, and re-cover the opening between the wall and the ceiling, and the cover plate 400 blocks the housing 100 to prevent the housing 100 from being directly exposed.

[0060] Optionally, two connection seats 402 are provided; the rotation shaft 401 passes through the upper end of the cover plate 400, and the two ends of the rotation shaft 401 are respectively rotatably connected to a corresponding connection seat 402. In this way, the two rotation seats are rotatably connected to the rotation shaft 401, thereby improving the stability of the connection.

[0061] Combination Figure 6 As shown, optionally, a guide block 410 is provided on a side wall of the cover plate 400 facing the housing 100. When the housing 100 slides out under the cooperation of the first sliding member 200 and the second sliding member 300, the housing 100 moves toward the guide block 410 and lifts the guide block 410 and the cover plate 400. In this way, the housing 100 moves toward the guide block 410, the housing 100 first contacts the guide block 410, and pushes the guide block 410, thereby driving the cover plate 400 to rotate, so that the opening is exposed, and at the same time, the cover plate 400 is prevented from interfering with the housing 100 sliding out from between the wall and the ceiling. When the housing 100 moves away from the guide block 410, the guide block 410 moves with the housing 100, thereby driving the cover plate 400 to move, so that the cover plate 400 covers the opening between the wall and the ceiling. When the housing 100 is retracted between the wall and the ceiling, the cover plate 400 is covered at the opening.

[0062] Combination Figure 7As shown, optionally, the guide block 410 includes: a straight block 411 and a raised block 412. The straight block 411 is fixedly connected to a side wall of the cover plate 400 facing the housing 100, and the side of the straight block 411 facing away from the cover plate 400 is the first side 413; the raised block 412 is fixedly connected to the lower end of the straight block 411, and the side of the raised block 412 connected to the first side 413 is the second side 414; wherein the second side 414 is an arc-shaped side. In this way, through the cooperation of the straight block 411 and the raised block 412, the first side 413 and / or the second side 414 are in contact with the housing 100, and the cover plate 400 is driven to rotate under the push of the housing 100.

[0063] Optionally, in the horizontal direction, the length of the lower end of the protruding block 412 is greater than the length of the upper end of the protruding block 412. In this way, the length of the lower end of the protruding block 412 is relatively long, and when the housing 100 is completely pulled out from between the wall and the ceiling, the lower end of the protruding block 412 contacts the upper side wall of the housing 100, so that a large gap is left between the cover plate 400 and the housing 100, which is convenient for observation and maintenance.

[0064] Optionally, a guide plate 500 is provided on the housing 100. In this way, when the housing 100 slides out from between the wall and the ceiling, the guide plate 500 replaces the housing 100 to contact the guide block 410, and the guide plate 500 pushes the guide block 410, thereby driving the cover plate 400 to rotate. At the same time, the guide plate 500 provides guide support for the guide block 410, and the surface of the guide plate 500 is relatively flat, so the relative sliding of the guide plate 500 and the guide block 410 is smoother.

[0065] Optionally, the guide plate 500 includes: a horizontal plate 510, a transition plate 520, and a vertical plate 530. The horizontal plate 510 is disposed on the upper side of the housing 100; the vertical plate 530 is disposed on the front side of the housing 100; one end of the transition plate 520 is fixedly connected to one end of the horizontal plate 510, and the other end of the transition plate 520 is fixedly connected to one end of the vertical plate 530. In this way, the vertical plate 530, the transition plate 520, and the horizontal plate 510 cooperate with each other to replace the housing 100 in contact with the guide block 410, and provide guide support for the guide block 410 in multiple directions of the housing 100.

[0066] Specifically, the horizontal plate 510 is fixedly connected to the upper side wall of the housing 100 .

[0067] Specifically, the vertical plate 530 is fixedly connected to the front side wall of the housing 100 .

[0068] Optionally, the transition plate 520 is an arc-shaped plate structure. In this way, since the angle between the horizontal plate 510 and the vertical plate 530 is relatively large, if the guide block 410 moves directly from the vertical plate 530 to the horizontal plate 510, the risk of the guide block 410 jumping is relatively large, making the cover plate 400 and the wall body at a greater risk of collision. Therefore, when the transition plate 520 of the arc-shaped plate structure provides a guide support for the guide block 410, the risk of the guide block 410 jumping is reduced.

[0069] Combination Figure 8 As shown, optionally, an air outlet 120 is provided on the front side wall of the housing 100. In this way, the heat-exchanged air is blown into the room through the air outlet 120.

[0070] Exemplarily, an integrated panel connected to the air outlet 120 may also be provided at the air outlet 120 , and when the housing 100 is retracted between the wall and the ceiling, the integrated panel covers the opening between the wall and the ceiling.

[0071] Specifically, the vertical plate 530 is connected to the edge of the air outlet 120 .

[0072] Optionally, a plurality of ventilation holes 420 are provided on the cover plate 400. Thus, by providing a plurality of ventilation holes 420, the airflow blown out of the air outlet 120 is conveniently blown out through the ventilation holes 420.

[0073] Optionally, a pull-out rod 130 is provided on the lower side wall of the housing 100, the pull-out rod 130 extends toward the cover plate 400, and the pull-out rod 130 passes through the cover plate 400. In this way, the pull-out rod 130 can be directly pulled to drive the housing 100 to slide out between the wall and the ceiling, which makes the operation more convenient and improves the user experience.

[0074] Optionally, a position avoidance hole 430 is provided at the bottom of the cover plate 400, and the pull-out rod 130 extends into the position avoidance hole 430. In this way, by providing the position avoidance hole 430, a position avoidance space is reserved for the pull-out rod 130.

[0075] Optionally, a connecting hole 131 is provided at one end of the pull-out rod 130 facing away from the housing 100. In this way, an auxiliary tool can be connected through the connecting hole 131, and the efficiency of pulling the pull-out rod 130 is improved by the auxiliary tool.

[0076] Optionally, a thread is provided on the hole wall of the connection hole 131. In this way, the auxiliary tool is connected by the thread on the hole wall of the connection hole 131, and the strength of the connection is higher.
