[0057] The principles and features of the present application will be described below with reference to the accompanying drawings. The examples given are only for explaining the present application and are not used to limit the scope of the present application.

[0058] As Figure 1 and Figure 2 shown, an air duct machine provided by an embodiment of the present application includes: a detachable blowing module 1 and a suction module 2. As Figure 12 and Figure 21 shown, the suction module 2 may include a housing and an indoor fan 21 provided in the housing, such as a cross-flow fan. As Figure 7 and Figure 9 shown, the blowing module 1 may include a housing and an indoor heat exchanger 11 provided in the housing. The air outlet 12 of the air duct machine is provided on the housing of the blowing module 1 and may be arranged forward so as to blow air forward, as Figure 7 shown. The air return opening 22 of the air duct machine is provided on the housing of the suction module 2 and is arranged downward so as to suck air upward, as Figure 19 and Figure 21 shown. When the air duct machine works, the indoor fan 21 rotates, sucks indoor air into the suction module 2 through the air return opening 22, enters the blowing module 1 through the indoor fan 21, and is blown into the indoor space through the air outlet 12 after heat exchange by the indoor heat exchanger 11.

[0059] As Figure 1 and Figure 2 shown, both the blowing module 1 and the suction module 2 are provided with a sliding mechanism 4. The sliding mechanism 4 is configured to be slidably engaged with a slide rail 3 fixed to the ceiling 5 and supported by the slide rail 3 so that the blowing module 1 and the suction module 2 are hoisted on the slide rail 3, as Figure 3As shown, the blowing module 1 and the suction module 2 are arranged side by side along the extending direction of the slide rail 3. The blowing module 1 and the suction module 2 are usually arranged side by side along the width direction of the air return opening 22, so the extending direction of the slide rail 3 is also the same as the width direction of the air return opening 22.

[0060] The air duct machine provided by the embodiment of the present application adopts a modular combined design, and the air duct machine is split into a detachable blowing module 1 and a suction module 2. During installation, the slide rail 3 can be fixed to the ceiling 5 first, and then the blowing module 1 and the suction module 2 are respectively hung on the slide rail 3 and slid to the required installation position and then the two are connected. Since the individual blowing module 1 and suction module 2 are small in volume and light in weight, multiple people are not required to work together, and single-person installation can be achieved, thereby reducing the installation cost of the air duct machine.

[0061] In some exemplary embodiments, such as Figures 3 to 6 As shown, the widths of the blowing module 1 and the suction module 2 along the extending direction of the slide rail 3 are both set to be smaller than the width of the air return opening provided on the ceiling 6. The air return opening provided on the ceiling 6 corresponds to and communicates with the air return opening 22 on the outer shell of the air duct machine. The air return opening provided on the ceiling 6 is also used as a maintenance opening 61, and an air return grille 62 can be provided at the maintenance opening 61 (as Figure 3 As shown), and the air return grille 62 is removed when maintenance is required. Therefore, the size of the air return opening provided on the ceiling 6 is larger than the air return opening 22 on the outer shell of the air duct machine to facilitate later maintenance.

[0062] Since the width of the air return opening provided on the conventional air duct machine ceiling 6 is 250 mm, the widths of the blowing module 1 and the suction module 2 along the extending direction of the slide rail 3 (i.e., the width in the front-rear direction) are both less than 250 mm. In this way, during later maintenance, both the blowing module 1 and the suction module 2 can be removed through the maintenance opening 61 on the ceiling 6, as Figures 4 to 6 As shown. When replacing the air duct machine, the ceiling 6 does not need to be damaged. The blowing module 1 and the suction module 2 of the old air duct machine are directly disassembled, and then taken down from the maintenance opening 61 of the ceiling 6 in sequence. Then, the blowing module 1 and the suction module 2 of the new air duct machine are sequentially installed into the ceiling 6 from the maintenance opening 61 of the ceiling 6 and hung on the slide rail 3, and then connected after sliding into place, thereby realizing the replacement of the air duct machine without breaking the ceiling, and single-person disassembly and assembly operations can be achieved, thereby reducing the installation and maintenance costs of the air duct machine.

[0063] In some exemplary embodiments, both the blowing module 1 and the suction module 2 include a housing. As Figure 10 And Figure 14 As shown, the sliding mechanism 4 includes: a hook assembly 42 and a spring lock assembly 41. The hook assembly 42 and the spring lock assembly 41 are respectively arranged at opposite ends of the housing. The number of slide rails 3 can be two, such as Figure 1 And Figure 2As shown, the two slide rails 3 correspond to the hook assembly 42 and the spring lock assembly 41 one by one.

[0064] The hook assembly 42 is configured to be capable of hooking and cooperating with the slide rail 3 and sliding along the slide rail 3.

[0065] The spring lock assembly 41 is configured to be supported by the slide rail 3 and slide along the slide rail 3, and the spring lock assembly 41 can switch between an extended state and a retracted state in a direction perpendicular to the slide rail 3. Based on switching to the extended state, the spring lock assembly 41 is supported by the slide rail 3; based on switching to the retracted state, the spring lock assembly 41 is disengaged from the support of the slide rail 3.

[0066] In this way, during installation, the hook assembly 42 of the blowing module 1 can be first hooked on the slide rail 3, and then the other end of the blowing module 1 is pushed upward, so that the spring lock assembly 41 of the blowing module 1 moves upward. During the upward movement of the spring lock assembly 41, the spring lock assembly 41 is first switched to the retracted state to avoid the slide rail 3, so as to prevent the spring lock assembly 41 from interfering with the slide rail 3; when the spring lock assembly 41 rises to the in-place position, the spring lock assembly 41 is then switched to the extended state, so that the spring lock assembly 41 is supported on the slide rail 3. In this way, both ends of the blowing module 1 are supported by the slide rail 3, and the blowing module 1 can be hoisted on the slide rail 3, and then the blowing module 1 is pushed to the appropriate installation position.

[0067] Then, the suction module 2 is installed in the same way. When the suction module 2 is pushed to the appropriate installation position, the suction module 2 is connected to the blowing module 1.

[0068] In some exemplary embodiments, as Figure 8 and Figure 11 shown, the slide rail 3 includes: a mounting frame 31 and a support plate 32.

[0069] Among them, the mounting frame 31 is fixed to the ceiling 5 through a suspension rod 33, as Figure 3 shown. The suspension rod 33 may include a fixing bolt, and the mounting frame 31 is provided with a through hole 322, as Figure 8 shown, and the fixing bolt passes through the through hole 322 and is fixed to the ceiling 5. The through hole 322 may be an oblong hole. The through hole 322 may be provided with a notch 323 (as Figure 8 shown) that penetrates one end of the mounting frame 31 away from the housing, so that the rod portion of the fixing bolt can enter the through hole 322 along the notch 323, but the width of the through hole 322 is smaller than the size of the head of the bolt or the nut 331 (as Figure 11 shown) sleeved on the bolt, so that the mounting frame 31 can be supported by the bolt.

[0070] The support plate 32 is connected to the mounting frame 31 and is provided with a sliding groove 321 extending along the extension direction of the slide rail 3, as Figure 8As shown, the hook assembly 42 is arranged to pass through the sliding groove 321 and be hooked on the bottom wall of the sliding groove 321 and can slide along the sliding groove 321. The spring lock assembly 41 is arranged to pass through the sliding groove 321 and be supported by the bottom wall of the sliding groove 321 and can slide along the sliding groove 321.

[0071] The mounting bracket 31 and the support plate 32 can be of an integral structure. The slide rail 3 can also include a folded edge 34. As Figure 8 and Figure 11 shown, the upper end of the support plate 32 is connected to the mounting bracket 31, and the lower end of the support plate 32 is connected to the folded edge 34, so that the slide rail 3 is generally in a U-shaped structure as a whole.

[0072] In some exemplary embodiments, the sliding groove 321 is provided with a limiting rib 324 for abutting against the hook assembly 42 or the spring lock assembly 41. As Figure 8 shown, the limiting rib 324 is arranged to position the relative position of the outer shell and the slide rail 3.

[0073] In this way, during the process of pushing the blowing module 1 or the suction module 2, when it is pushed to the position where the outer shell abuts against the limiting rib 324, it means that the sliding is in place. In this way, there is no need for the operator to subjectively position the blowing module 1 and the suction module 2, which is beneficial to reducing the installation difficulty and disassembly difficulty of the air duct machine.

[0074] It can be that during the installation process, the blowing module 1 is installed first. When the blowing module 1 slides to the position where the outer shell abuts against the limiting rib 324, it means that the blowing module 1 slides in place. Then the suction module 2 is installed, and the suction module 2 is moved towards the blowing module 1 until it is docked and fixed with the blowing module 1. During the disassembly process, the suction module 2 is unlocked and separated from the blowing module 1, and then the suction module 2 is pulled towards the maintenance opening 61 of the ceiling 6. When the suction module 2 slides to the position where the outer shell abuts against the limiting rib 324, the suction module 2 can be removed from the slide rail 3 and then taken out from the maintenance opening 61 of the ceiling 6, as Figure 4 shown. Then the blowing module 1 is removed in the same way. First, the blowing module 1 is pulled towards the maintenance opening 61 of the ceiling 6 (as Figure 5 shown), and then the blowing module 1 is taken out from the maintenance opening 61 of the ceiling 6 (as Figure 6 shown).

[0075] In some exemplary embodiments, the bottom wall of the sliding groove 321 is provided with a turned-up edge 325 that turns towards the direction away from the outer shell. As Figure 8 and Figure 11 shown, the turned-up edge 325 is arranged to support the hook assembly 42 and / or the spring lock assembly 41.

[0076] This can increase the contact area between the slide rail 3 and the hook assembly 42 and the spring lock assembly 41, which is beneficial to improving the support reliability of the slide rail 3 for the blowing module 1 and the suction module 2.

[0077] In some exemplary embodiments, such as Figures 23 to 25 As shown, the spring lock assembly 41 includes: a first bottom plate 411, a first cavity 412, an elastic member 414, and a sliding support member 413. The outer shell can be a sheet metal part. The first bottom plate 411, the first cavity 412, and the sliding support member 413 can be metal parts to ensure the structural strength of the spring lock assembly 41. The elastic member 414 can be a spring.

[0078] Among them, the first bottom plate 411 is fixedly connected to the first end of the outer shell (which can be the left end or the right end of the outer shell). The first bottom plate 411 can be fixedly connected to the outer shell by fasteners (such as screws), welding, etc.

[0079] The first cavity 412 is fixedly connected to the first bottom plate 411, and a first opening 4120 is provided at one end of the first cavity 412 away from the first bottom plate 411. The first cavity 412 can be fixedly connected to the first bottom plate 411 by fasteners (such as screws).

[0080] One end of the sliding support member 413 is limited in the first cavity 412, and the other end of the sliding support member 413 can pass through the first opening 4120 and extend out of the first cavity 412 and be supported by the slide rail 3. The sliding support member 413 is arranged to be able to move between an extended position and a retracted position along a direction perpendicular to the slide rail 3, so that the spring lock assembly 41 can be switched between an extended state and a retracted state.

[0081] The elastic member 414 is arranged in the first cavity 412 and abuts against the sliding support member 413, and is arranged to be able to drive the sliding support member 413 to move from the retracted position to the extended position by its restoring elastic force.

[0082] In this way, when the spring lock assembly 41 rises to the in-place position, it can automatically switch to the extended state without manual operation by the operator, which is beneficial to further reducing the installation difficulty of the air duct machine.

[0083] In some embodiments, a guiding inclined surface is provided at the upper end of the sliding support member 413, and the guiding inclined surface is arranged to cooperate with the slide rail 3 to make the sliding support member 413 move from the extended position to the retracted position, so that the spring lock assembly 41 is switched to the retracted state. In this way, during the rising process of the spring lock assembly 41, it can automatically switch to the retracted state under the action of the slide rail 3 to avoid interference with the slide rail 3 without manual operation by the operator, which is beneficial to further reducing the installation difficulty of the air duct machine.

[0084] In some embodiments, such as Figures 23 to 25As shown, the first cavity 412 includes a first bottom shell 4121 and a first cover shell 4122 which are connected in a covering manner. The first bottom shell 4121 includes a first bottom wall 4123, a first side wall 4124, and two first end walls 4125 which are oppositely arranged along the extending direction of the slide rail 3. The first cover shell 4122 includes a first top wall 4126, a second side wall 4127, and two second end walls 4128 which are oppositely arranged along the extending direction of the slide rail 3. The first side wall 4124, the second side wall 4127, and the first bottom plate 411 are stacked and fixedly connected by fasteners. First lugs 4111 may be provided at both ends of the first bottom plate 411 along the length direction of the slide rail 3. The first lugs 4111, the first end walls 4125, and the second end walls 4128 on the same side are stacked and fixedly connected by fasteners. A limit protrusion 4131 may be provided at one end of the sliding support 413 located inside the first cavity 412, and a limit step 4129 may be provided at the first opening 4120. The limit protrusion 4131 abuts against the limit step 4129 to prevent the sliding support 413 from disengaging from the first cavity 412.

[0085] During installation, one end of the elastic member 414 and the sliding support 413 can be first placed between the first bottom shell 4121 and the first cover shell 4122, and then the first bottom shell 4121, the first cover shell 4122, and the first bottom plate 411 are fixedly connected. In this way, the spring lock assembly 41 is connected by multiple fasteners, which is beneficial to improving the structural strength of the spring lock assembly 41.

[0086] In some exemplary embodiments, as Figures 26 to 28 shown, the hook assembly 42 includes: a second bottom plate 421, a second cavity 422, and a hook support 423. The outer shell can be a sheet metal part. The second bottom plate 421, the second cavity 422, and the hook support 423 can be metal parts to ensure the structural strength of the hook assembly 42.

[0087] Among them, the second bottom plate 421 is fixedly connected to the second end of the outer shell (the end opposite to the first end of the outer shell, which can be the right end or the left end of the outer shell). The second bottom plate 421 can be fixedly connected to the outer shell by fasteners (such as screws), welding, etc.

[0088] The second cavity 422 is fixedly connected to the second bottom plate 421, and a second opening 4220 is provided at one end of the second cavity 422 away from the second bottom plate 421. The second cavity 422 can be fixedly connected to the second bottom plate 421 by fasteners (such as screws).

[0089] One end of the hook support 423 is fixed inside the second cavity 422. The other end of the hook support 423 passes through the second opening 4220 and extends out of the second cavity 422, and is provided with a hook portion 4231 extending downward.

[0090] In this way, the hook support 423 can be engaged with the slide rail 3 in a hooked manner, and the hook portion 4231 can prevent the hook support 423 from disengaging from the slide rail 3.

[0091] In some embodiments, as Figures 26 to 28 shown, the second cavity 422 includes a second bottom shell 4221 and a second cover shell 4222 that are connected in a covering manner. The second bottom shell 4221 includes a second bottom wall 4223, a third side wall, and two third end walls 4225 that are oppositely arranged along the extending direction of the slide rail 3. The second cover shell 4222 includes a second top wall 4226, a fourth side wall, and two fourth end walls 4228 that are oppositely arranged along the extending direction of the slide rail 3. The third side wall, the fourth side wall, and the second bottom plate 421 are stacked and fixedly connected by fasteners. One end of the hook support 423 close to the second bottom plate 421 can also be stacked with the third side wall or the fourth side wall and fixedly connected by the fasteners. Second lugs 4211 can also be provided at both ends of the second bottom plate 421 along the length direction of the slide rail 3. The second lugs 4211, the third end walls 4225, and the fourth end walls 4228 on the same side are stacked and fixedly connected by fasteners. One end of the hook support 423 close to the second lugs 4211 can also be stacked with the third end wall 4225 or the fourth end wall 4228 and fixedly connected by the fasteners.

[0092] During installation, the hook support 423 can be first inserted between the second bottom shell 4221 and the second cover shell 4222, and then the second bottom shell 4221, the second cover shell 4222, and the second bottom plate 421 are fixedly connected. In this way, the hook assembly 42 is connected by multiple fasteners, which is beneficial to improving the structural strength of the hook assembly 42.

[0093] In some embodiments, the hook assembly 42 is located on the left side of the housing, and the spring lock assembly 41 is located on the right side of the housing.

[0094] In some exemplary embodiments, as Figure 18 、 Figure 20 and Figure 22 shown, a first seal 14 is provided at one end of the blowing module 1 close to the suction module 2, and the first seal 14 is sleeved on the port of the blowing module 1 facing the suction module 2. A second seal 24 is provided at one end of the suction module 2 close to the blowing module 1, and the second seal 24 is sleeved on the port of the suction module 2 facing the blowing module 1.

[0095] One of the first seal 14 and the second seal 24 is provided with a sealing groove 241 adapted to the other, as Figure 20 and Figure 22 shown, and the other is inserted into the sealing groove 241.

[0096] In this way, the first seal 14 and the second seal 24 form a nested seal structure in the shape of a Chinese character 'hui'. When the air flow inside the air duct machine wants to leak out through the gap between the blowing module 1 and the air suction module 2, it needs to bend and move forward along the seal groove 241, and the flow path is greatly extended, which is beneficial to improving the sealing performance between the air suction module 2 and the blowing module 1 and reducing the risk of air leakage.

[0097] In some exemplary embodiments, the first seal 14 and the second seal 24 are rigid seals. This facilitates pre-installing the first seal 14 and the second seal 24 on the outer shell of the blowing module 1 and the outer shell of the air suction module 2, and is beneficial to ensuring the stability of the shapes and positions of the first seal 14 and the second seal 24 to improve the sealing reliability. It is also convenient to use the first seal 14 and the second seal 24 to achieve detachable connection between the air suction module 2 and the blowing module 1. The first seal 14 and the second seal 24 can be fixed on the outer shell of the blowing module 1 and the outer shell of the air suction module 2 through fasteners (such as screws). The rigid seal can be a plastic seal.

[0098] A soft sealing ring 25 is also provided between the first seal 14 and the second seal 24, such as Figure 20 and Figure 22 shown. In this way, the sealing performance between the air suction module 2 and the blowing module 1 can be further improved, and the risk of air leakage can be further reduced. The soft sealing ring 25 can be a rubber sealing ring.

[0099] In some exemplary embodiments, an installation groove 242 for installing the soft sealing ring 25 is provided on the end face of the first seal 14 facing the air suction module 2 and / or the end face of the second seal 24 facing the blowing module 1, such as Figure 22 shown.

[0100] In this way, it is convenient to pre-install the soft sealing ring 25 on the blowing module 1 or the air suction module 2. After the air suction module 2 and the blowing module 1 are docked, the soft sealing ring 25 can be clamped to achieve the installation and fixation of the soft sealing ring 25.

[0101] In some embodiments, such as Figure 20 and Figure 22As shown, the port of the blowing module 1 facing the suction module 2 is provided with a first step flange 13, and the port of the suction module 2 facing the blowing module 1 is provided with a second step flange 23. The first seal 14 is sleeved on the first step flange 13, and the second seal 24 is sleeved on the second step flange 23. The first seal 14 and the second seal 24 are hollow structures. The cross section of the first seal 14 is n-shaped, and the cross section of the second seal 24 is h-shaped. The h-shaped opening of the second seal 24 is arranged opposite to the n-shaped opening of the first seal 14, and the second seal 24 is provided with a sealing groove 241. After the first seal 14 and the second seal 24 are connected, the edge 243 of the second seal 24 surrounds the outside of the first seal 14 to cover the first seal 14. The radial inner end of the second seal 24 is provided with a mounting groove 242.

[0102] In some exemplary embodiments, Figure 18 and Figure 20 As shown, one of the first sealing member 14 and the second sealing member 24 with the sealing groove 241 is provided with a buckle 245, and the other is provided with a clamping groove 142, and the buckle 245 is clamped with the clamping groove 142. The clamping method is convenient for assembly and disassembly, which is conducive to further reducing the installation and maintenance costs of the duct machine.

[0103] In some exemplary embodiments, Figures 16 to 18 as well as Figure 20 As shown, one of the first sealing member 14 and the second sealing member 24 that is provided with the buckle 245 is also provided with an escape groove 246 and a hand-held portion 247 provided at the escape groove 246. The buckle 245 is located in the escape groove 246 and is connected to the hand-held portion 247, and the hand-held portion 247 is configured to be moved to drive the buckle 245 to escape from the slot 142. The hand-held portion 247 may be an L-shaped folding plate. The escape groove 246 facilitates the elastic deformation of the hand-held portion 247 and the buckle 245.

[0104] In this way, during installation, when the suction module 2 and the blowing module 1 are docked, the buckle 245 can automatically snap into the slot 142 to achieve self-locking. During disassembly, the suction module 2 and the blowing module 1 can be unlocked by moving the handheld portion 247, and then the suction module 2 can be separated from the blowing module 1 by pulling it.

[0105] In some exemplary embodiments, a positioning portion is provided at one end of the first seal 14 close to the second seal 24, and a positioning matching portion is provided at one end of the second seal 24 close to the first seal 14. The positioning portion and the positioning matching portion are plugged into each other to position the relative positions of the blowing module 1 and the suction module 2.

[0106] This makes it easier to position the air suction module 2 and the air blowing module 1 first and then fix them, which helps to further reduce the difficulty of installing the duct machine.

[0107] Among them, the positioning part can be a positioning protrusion 141 (as shown in Figure 15 ), and the positioning mating part can be a positioning groove 244 (as shown in Figure 13 ). The positioning protrusion 141 can be arranged at the four corners of the first seal 14, and the positioning groove 244 can be arranged at the four corners of the second seal 24. The positioning protrusion 141 and the positioning groove 244 can also be provided with guiding inclined surfaces to facilitate the smooth insertion of the positioning protrusion 141 into the positioning groove 244.

[0108] In summary, the air duct machine provided by the embodiment of the present application is a combined ceiling machine, which adopts a combined design, includes a blowing module and a suction module, is combined into one by snap fasteners, and is sealed by a rubber sealing ring. Each module can be disassembled and assembled by one person alone.

[0109] When installing the air duct machine by one person, first hang the hook assembly on the left side of the blowing module into the slide rail, and then push the spring lock assembly on the right side of the blowing module upward. The spring lock assembly moves into the chute of the slide rail and automatically pops out, and can slide freely in the chute.

[0110] When the blowing module slides to the limiting rib in the slide rail, then hang the hook assembly on the left side of the suction module into the slide rail, and then push the spring lock assembly on the right side of the suction module upward. The spring lock assembly moves into the chute of the slide rail and automatically pops out, and can slide freely in the chute.

[0111] Quickly position the blowing module through the positioning protrusion of the blowing module and the positioning groove of the suction module, and fix the two modules by snap fasteners.

[0112] The blowing module and the suction module are matched with a "square frame" sealing structure, and a rubber sealing ring is used to prevent air leakage.
