When disassembling or installing the volutes, each volute needs to be disassembled or installed separately, making the disassembly and installation of the volutes complicated and tedious. Summary of the invention

[0003] The problem solved by the invention is how to improve the convenience of disassembly and installation of the volute.

[0004] In order to solve the above problems, the present invention provides a volute mounting structure, including a partition, a volute assembly, a top cover plate, a spring-lock mechanism and a snap-lock structure, the volute assembly includes a mounting plate and a volute, the mounting plate and the partition are detachably connected via the snap-lock structure, the mounting plate and the top cover plate are detachably connected via the spring-lock mechanism, the volute is arranged on the mounting plate and is located on the side of the mounting plate away from the partition.

[0005] Therefore, by setting a mounting plate, and the partition and the top cover plate are detachably connected to the mounting plate, the stability of the volute assembly in the duct machine is enhanced, and the convenience of disassembly or installation between the volute assembly and the partition and the top cover plate is improved; the volute is installed on the mounting plate, so that when the volute assembly or the heat exchanger needs to be maintained or cleaned, it is only necessary to remove the mounting plate of the volute assembly from the partition, and the mounting plate and the volute can be taken out together, without removing the volute of the volute assembly one by one. In this way, the volute assembly can be removed from the partition as a whole or installed on the partition as a whole, which facilitates the disassembly and installation of the volute assembly, that is, improves the convenience of disassembly and installation of the volute; in addition, due to the improvement of the convenience of disassembly and installation of the volute, it is also convenient to clean the heat exchanger in the duct machine.

[0006] Optionally, the spring-clip mechanism includes a mounting seat, a spring-clip arranged on the mounting seat, a spring and a button, the mounting seat and the mounting plate are integrally formed, one end of the spring-clip is connected to the button, and the other end is connected to the spring, and the end of the spring away from the spring-clip is connected to the mounting seat; and a limiting hole is provided on the top cover plate, and the spring-clip is engaged with the limiting hole.

[0007] As a result, the top cover plate limits the spring buckle (volute assembly) through the hole wall of the limiting hole to prevent the volute assembly from moving forward, downward, and left and right, thereby improving the stability of the connection between the volute assembly and the top cover plate.

[0008] Optionally, the mounting seat includes a mounting seat body and a fixing plate, the button passes through the fixing plate to be connected to the spring buckle, and the button extends out of the fixing plate away from an end connected to the spring buckle.

[0009] Therefore, a first through hole suitable for the button to move in the front-to-back direction is provided on the fixing plate, and the end of the button away from the connection with the spring hook extends forward from the fixing plate through the first through hole, so as to facilitate the installer to press the button, and after the installer removes the pressing force on the button, the button returns to the position before pressing under the action of the spring; the end of the spring hook away from the fixing plate is columnar, and a spring is sleeved on it, and a second through hole is provided at the connection between the mounting seat body and the spring, and the end of the spring hook away from the fixing plate is arranged through the second through hole, so as to facilitate the spring hook to move backward when the button is pressed; in this way, the mounting seat limits the spring hook in the up-down direction and the left-right direction through the first through hole and the second through hole to ensure the stability of the spring hook when it moves in the front-to-back direction.

[0010] Optionally, the extension length of the button away from the end connected to the snap button extending out of the fixing plate is greater than the assembly stroke of the snap button mechanism.

[0011] Thus, when the installer presses the button, the button is prevented from falling out of the first through hole, thereby preventing the difficulty of assembling the volute assembly from increasing.

[0012] Optionally, a boss is further provided on the top cover plate, and the limiting hole is arranged on the boss.

[0013] Therefore, the boss is set on the top cover plate, and can be protruding in the direction away from the volute or protruding in the direction of the volute, and a limiting hole is provided on the boss for engaging with the spring buckle to ensure the stability of the volute assembly when connected to the top cover plate.

[0014] Optionally, the boss is located on a side of the top cover plate facing the volute assembly.

[0015] Therefore, the boss is preferably protruded from the top cover plate toward the volute, so that the side of the boss away from the volute is a recessed structure, and the end of the spring buckle that is inserted into the limiting hole is located in the recessed structure; in this way, by setting the boss, on the one hand, the recessed structure on the side of the boss away from the volute can protect the end of the spring buckle that is inserted into the limiting hole, and on the other hand, after the spring buckle is upwardly inserted into the limiting hole, the spring buckle will not protrude from the side of the top cover plate away from the volute, thereby ensuring the flatness of the side of the top cover plate away from the volute, so as to facilitate the assembly of the duct unit on the indoor wall.

[0016] Optionally, a connecting plate is further provided on the top cover plate, and the boss is arranged on the connecting plate.

[0017] Therefore, a connecting plate is provided between the boss and the top cover plate, and the boss and the connecting plate form a cavity for accommodating the spring clip to snap into one end of the limiting hole, so that the volute assembly and the top cover plate can be connected through the boss and the connecting plate.

[0018] Optionally, the buckle structure includes a limit buckle; the limit buckle is arranged on the mounting plate, and a limit slot is provided at a position on the partition corresponding to the limit buckle, and / or the limit buckle is arranged on the partition, and a limit slot is provided at a position on the mounting plate corresponding to the limit buckle; and the limit buckle is engaged with the limit slot.

[0019] Thus, the mounting plate and the partition are detachably connected through the snap-fit ​​structure, and the limit snap (limit snap slot) on the mounting plate is snap-fitted with the corresponding limit snap slot (limit snap) on the partition to ensure the stability of the volute assembly when connected to the partition and the convenience of disassembly and installation. Based on the snap-fitting of the spring buckle and the limit hole, the stability of the volute assembly in the duct unit is further improved.

[0020] Optionally, the buckle structure also includes a positioning buckle; the positioning buckle is arranged on the mounting plate, and a positioning slot is provided at a position on the partition corresponding to the positioning buckle, and / or the positioning buckle is arranged on the partition, and a positioning slot is provided at a position on the mounting plate corresponding to the positioning buckle; and the positioning buckle is engaged with the positioning slot.

[0021] Therefore, based on the snap-fitting cooperation between the spring buckle and the limiting hole, the snap-fitting cooperation between the limiting slot and the limiting buckle, and the snap-fitting cooperation between the positioning buckle and the positioning slot, the stability of the volute assembly in the duct machine is further improved.

[0022] Optionally, an overlapping edge structure is provided at the matching position between the limiting buckle and the limiting slot, and / or at the matching position between the positioning buckle and the positioning slot.

[0023] Therefore, the thickness of the partition at the overlapped edge structure is greater than the thickness of the partition at other places, so as to improve the structural strength of the partition at the snap-fitting part between the limit buckle and the limit slot and / or the snap-fitting part between the positioning buckle and the positioning slot, thereby improving the stability of the volute assembly when connected to the partition.

[0024] Optionally, the snap-on structure includes a snap-on; the snap-on is arranged at the upper end of the mounting plate, and a positioning groove is provided at the upper end of the partition, and / or the positioning groove is provided at the upper end of the mounting plate, and the snap-on is arranged at the upper end of the partition; and the snap-on is snap-fitted with the positioning groove.

[0025] Therefore, a clip and / or a positioning groove is provided on the mounting plate, a positioning groove and / or a clip is provided on the partition, and the clip (positioning groove) on the mounting plate corresponds to the positioning groove (clip) on the partition; by providing the clip and the positioning groove, the stability of the connection between the mounting plate and the partition is further ensured, while the disassembly and installation between the mounting plate and the partition are facilitated.

[0026] Optionally, a mounting hole is provided at the lower end of the mounting plate, and a matching hole adapted to the mounting hole is provided at the lower end of the partition, and the mounting plate and the partition are detachably connected at the mounting hole and the matching hole by fasteners.

[0027] Therefore, the mounting plate and the partition are detachably connected by fasteners to ensure the stability of the connection between the mounting plate and the partition and to facilitate the disassembly of the mounting plate and the partition; the mounting hole is arranged at the lower end of the mounting plate, and the position of the mating hole corresponds to the position of the mounting hole to avoid the mounting hole being blocked by components such as the volute when the mounting hole is arranged at the upper end of the mounting plate, thereby increasing the difficulty of installation and disassembly between the mounting plate and the partition.

[0028] Optionally, the partition is provided with the positioning groove, the buckle is protruded on the side of the mounting plate facing the partition, and the buckle and the mounting plate form a slot, and the angle between the slot wall on the mounting plate and the slot wall on the buckle is between 45° and 60°.

[0029] Therefore, after the mounting plate is installed on the partition, the buckle abuts against the lower groove wall of the positioning groove, and after the mounting plate and the partition are connected by fasteners, the partition limits the mounting plate to prevent the mounting plate from being displaced in the vertical direction, thereby ensuring the stability of the connection between the mounting plate and the partition, that is, ensuring the stability of the connection between the volute assembly and the partition; and the angle α between the groove wall of the slot on the mounting plate and the groove wall of the slot on the buckle satisfies 45°≤α≤60°, so as to ensure that the upper side of the buckle guides the buckle to the positioning groove, so as to improve the convenience of disassembly and installation of the volute, and after the buckle is inserted into the positioning groove, the partition can prevent the mounting plate from moving toward or away from the partition, so as to enhance the stability of the connection between the mounting plate and the partition.

[0030] Optionally, there is a gap between one end of the buckle connected to the mounting plate and an upper groove wall of the positioning groove.

[0031] Therefore, after the buckle is inserted into the positioning groove, the vertical distance between the upper groove wall and the lower groove wall of the positioning groove is greater than the maximum vertical distance from the lower groove wall of the positioning groove to the end of the buckle connected to the mounting plate; in this way, the buckle has sufficient space to move when it is inserted into the positioning groove, so that the buckle will not be hindered from being inserted due to the small vertical distance between the upper groove wall and the lower groove wall of the positioning groove, thereby facilitating the snap-on fit between the buckle and the positioning groove.

[0032] Optionally, a gap between one end of the buckle connected to the mounting plate and the upper groove wall of the positioning groove is between 2 mm and 4 mm.

[0033] Therefore, the gap h1 between one end of the buckle connected to the mounting plate and the upper groove wall of the positioning groove satisfies 2mm≤h1≤4mm, so as to achieve a balance between the convenience of installation and disassembly between the improving mounting plate and the partition plate, and ensuring that the airflow blown from the volute into the heat exchange chamber is difficult to flow back to the fan chamber through the gap between the buckle and the upper groove wall of the positioning groove.

[0034] Optionally, a vertical distance from the end of the clip that is away from the mounting plate to a position where the clip contacts the partition is between 3 mm and 5 mm.

[0035] Therefore, the vertical distance h2 from the end of the clip connected to the mounting plate to the position where the clip contacts the partition satisfies 3mm≤h2≤5mm; so that the convenience of disassembly and installation between the partition and the mounting plate is improved while preventing the clip from easily falling out of the positioning groove.

[0036] Optionally, the partition includes an integrally formed partition body and a flange, and the mounting plate is detachably connected to the partition body; the partition body is provided with an opening for communicating with the air outlet of the volute, the flange is arranged around the opening, and the flange is folded in a direction away from the mounting plate.

[0037] Therefore, the flange of the partition is arranged around the opening on the partition body, and the flange extends away from the end connected to the partition body in the direction away from the mounting plate. In this way, the flange can guide the airflow blown out from the volute so that the airflow is blown toward the heat exchanger in a direction to ensure the heat exchange effect of the heat exchanger; and the setting of the flange strengthens the structural strength of the partition, thereby improving the structural strength of the duct machine casing.

[0038] Optionally, a vertical distance from the end of the flange away from the partition body connected to the partition body to the partition body is between 3 mm and 5 mm.

[0039] Therefore, the protruding height h3 of the flange on the partition body satisfies 3mm≤h3≤5mm, so as to ensure the guiding effect of the flange on the airflow without increasing the difficulty of producing the partition.

[0040] In order to solve the above problem, the present invention also provides an air conditioner, comprising the above-mentioned volute mounting structure.

[0041] The advantages of the air conditioner and the above-mentioned volute mounting structure over the prior art are the same, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] Combination Figure 1 , Figure 2 , Fig. 9 As shown, the present invention provides a volute mounting structure, including a partition 1, a volute assembly 2, a top cover plate 3, a spring-lock mechanism 4 and a snap-lock structure 5, the volute assembly 2 includes a mounting plate 21 and a volute 22, the mounting plate 21 is detachably connected to the partition 1 via the snap-lock structure 5, the mounting plate 21 is detachably connected to the top cover plate 3 via the spring-lock mechanism 4, and the volute 22 is arranged on the mounting plate 21 and is located on the side of the mounting plate 21 away from the partition 1.

[0067] The fan assembly is applied to the air conditioner. This embodiment and the following text are all described by taking the fan assembly applied to the duct air conditioner (i.e., duct air conditioner) as an example. The housing of the duct air conditioner includes a top cover plate 3, a bottom plate, a left side plate, a right side plate and other panels (not shown in the figure), which are used to enclose a receiving cavity for accommodating the heat exchanger (not shown in the figure) and the volute mounting structure of the duct air conditioner, so as to protect the heat exchanger and the volute mounting structure. The top cover plate 3 is located at Fig. 9 In the positive direction of the middle Z axis, the chassis is located in the opposite direction of the Z axis, the left side plate is located in the opposite direction of the Y axis, and the right side plate is located in the positive direction of the Y axis. The partition 1 of the volute mounting structure is arranged in the housing of the duct machine, and is used to support panels such as the top cover plate 3 to improve the structural strength of the housing of the duct machine; and the partition 1 separates the accommodating cavity of the duct machine for accommodating components such as the heat exchanger and the volute mounting structure into a heat exchange cavity and a fan cavity. The heat exchanger of the duct machine is arranged in the heat exchange cavity, and the volute assembly 2 is arranged in the fan cavity. The volute assembly 2 includes a mounting plate 21 and a volute 22. In the present embodiment, the mounting plate 21 and the volute 22 may be detachably connected, or the mounting plate 21 and the volute 22 may be integrally formed. The volute 22 of the volute assembly 2 is detachably connected to the partition body 11 (described later) of the partition 1 through the mounting plate 21 to ensure the stability of the volute assembly 2 in the air duct machine and improve the convenience of disassembly or installation between the volute assembly 2 and the partition 1. The volute 22 is arranged on the side of the mounting plate 21 away from the partition body 11 (that is, the volute 22 is arranged on the side of the mounting plate 21 located at the Fig. 9and the mounting plate 21 is also detachably connected to the top cover plate 3. Specifically, a snap mechanism 4 is provided at one end of the mounting plate 21 located in the positive direction of the Z axis, and the mounting plate 21 and the top cover plate 3 are detachably connected via the snap mechanism 4. In this way, the stability of the volute assembly 2 in the duct machine is further enhanced, and the convenience of disassembly or installation between the volute assembly 2 and the top cover plate 3 is improved. The convenience of disassembly and installation between the volute assembly 2 and the partition 1 and the top cover plate 3 is improved, and it is also convenient to maintain, clean the volute assembly 2 or clean the heat exchanger after the volute assembly 2 is removed; specifically, when the mounting plate 21 is removed from the partition body 11 and the top cover plate 3, the volute 22 installed on the mounting plate 21 is also removed together, and can be taken out from the return air outlet of the duct machine, so as to maintain and clean the volute assembly 2 outside the duct machine; an air outlet is provided at one end of the volute 22 facing the partition body 11, and an opening 11 (described in detail later) for communicating with the air outlet of the volute 22 is provided on the partition 1, so that when the heat exchanger of the duct machine needs to be cleaned When cleaning, the mounting plate 21 and the volute 22 can be removed from the partition body 11 together, and then a water gun can be extended from the opening 11 on the partition body 11 into the heat exchange chamber to clean the heat exchanger located in the heat exchange chamber, thereby ensuring that the duct machine delivers fresh, high-quality cold air or warm air; on the other hand, since the duct machine is usually provided with multiple volutes 22 to ensure the air output of the duct machine, the present invention arranges a volute assembly 2 so that multiple volutes 22 are connected to the mounting plate 21, so that the multiple volutes 22 can be disassembled and installed as a whole, which facilitates the disassembly and installation of the volute 22 in the fan chamber of the duct machine, that is, the convenience of disassembly and installation of the volute 22 is improved.

[0068] By providing a mounting plate 21, and the partition 1 and the top cover plate 3 are both detachably connected to the mounting plate 21, the stability of the volute assembly 2 in the duct machine is enhanced, and the convenience of disassembly or installation between the volute assembly 2 and the partition 1 and the top cover plate 3 is improved; the volute 22 is installed on the mounting plate 21, so that when the volute assembly 2 or the heat exchanger needs to be maintained or cleaned, it is only necessary to remove the mounting plate 21 of the volute assembly 2 from the partition 1 and the top cover plate 3, and the mounting plate 21 and the volute 22 can be taken out together, without removing the volute 22 of the volute assembly 2 one by one. In this way, the volute assembly 2 can be removed from the partition 1 as a whole or installed on the partition 1 as a whole, which facilitates the disassembly and installation of the volute assembly 2, that is, the convenience of disassembly and installation of the volute 22 is improved; in addition, due to the improvement of the convenience of disassembly and installation of the volute 22, it is also convenient to clean the heat exchanger in the duct machine.

[0069] Optionally, combined Figure 3-Figure 5 , Figure 8 , Fig. 9As shown, the spring-clip mechanism 4 includes a mounting seat 41, a spring-clip 42 arranged on the mounting seat 41, a spring 43 and a button 44. The mounting seat 41 is integrally formed with the mounting plate 21. One end of the spring-clip 42 is connected to the button 44, and the other end is connected to the spring 43. The end of the spring 43 away from the spring-clip 42 is connected to the mounting seat 41; and a limiting hole 31 is provided on the top cover plate 3, and the spring-clip 42 is snap-fitted with the limiting hole 31.

[0070] The mounting seat 41 is located on the left and right sides of the mounting plate 21 (i.e. Figure 3 The upper ends of both sides of the volute assembly 2 (in the Y-axis direction) (i.e., the end of the mounting plate 21 located in the positive direction of the Z-axis) are arranged to facilitate the connection between the mounting plate 21 and the top cover plate 3; in the positive direction of the X-axis, the spring 43, the spring buckle 42, and the button 44 are connected in sequence. When the volute assembly 2 and the top cover plate 3 are assembled, the installer first presses the button 44 in the reverse direction of the X-axis to move the spring buckle 42 backward, and compresses the spring 43, and at this time applies an upward force to the volute assembly 2, so that the spring buckle 42 is stuck in the limiting hole 31 set on the top cover plate 3, and then releases the button 44, the spring 43 recovers its deformation (stretches), so that the spring buckle 42 abuts against the hole wall of the limiting hole 31 to complete the assembly of the volute assembly 2 and the top cover plate 3; and the end of the spring buckle 42 inserted into the limiting hole 31 is hook-shaped. After the spring buckle 42 is engaged with the limiting hole 31, the end of the spring buckle 42 inserted into the limiting hole 31 abuts against the side of the top cover plate 3 away from the volute 22; in this way, the top cover plate 3 limits the spring buckle 42 (volute assembly 2) through the hole wall of the limiting hole 31 to prevent the volute assembly 2 from moving forward (i.e. Fig. 9 X-axis positive), downward (i.e. Fig. 9 Z-axis in the opposite direction) and left and right (i.e. Fig. 9 The volute assembly 2 moves in the Y-axis direction, thereby improving the stability of the connection between the volute assembly 2 and the top cover plate 3.

[0071] Furthermore, in order to allow the spring buckle 42 to be smoothly inserted into the limiting hole 31, the mounting plate 21 must first be detachably connected to the partition 1 through the snap structure 5, so that after the mounting plate 21 is abutted against the partition 1, the mounting plate 21 can move upward along the side of the partition 1 toward one side of the mounting plate 21, thereby facilitating the spring buckle 42 to be inserted into the limiting hole 31, thereby completing the assembly of the volute assembly 2 with the partition 1 and the top cover plate 3.

[0072] Optionally, combined Figure 3-Figure 5 , Figure 8 , Fig. 9 As shown, the mounting seat 41 includes a mounting seat body 411 and a fixing plate 412 , the button 44 passes through the fixing plate 412 and is connected to the spring buckle 42 , and one end of the button 44 away from the connection with the spring buckle 42 extends out of the fixing plate 412 .

[0073] The fixing plate 412 is provided with a button 44 in the front-to-back direction (i.e. Fig. 9The first through hole 4121 that moves in the X-axis direction of the center, the end of the button 44 away from the spring buckle 42 extends forward from the fixing plate 412 through the first through hole 4121, so as to facilitate the installation personnel to press the button 44, and after the installation personnel remove the pressing force on the button 44, the button 44 returns to the position before pressing under the action of the spring 43; the end of the spring buckle 42 away from the fixing plate 412 is columnar, and the spring 43 is sleeved on it. A second through hole 4111 is provided at the connection between the mounting seat body 411 and the spring 43, and the end of the spring buckle 42 away from the fixing plate 412 passes through the second through hole 4111, so as to facilitate the spring buckle 42 to move backward when the button 44 is pressed; in this way, the mounting seat 41 moves the spring buckle 42 in the up and down directions (i.e. Fig. 9 The limit of the spring buckle 42 in the front-to-back direction (i.e. Fig. 9 and the mounting seat body 411 is L-shaped or T-shaped, so that the mounting seat body 411 and the fixing plate 412 cooperate to form an area for accommodating the spring buckle 42 and the spring 43 to protect the spring buckle 42 and the spring 43, thereby ensuring the smooth assembly of the volute assembly 2 in the duct machine.

[0074] Optionally, combined Fig. 9 As shown, the extension length of the button 44 away from the end connected to the snap 42 extending out of the fixing plate 412 is greater than the assembly stroke of the snap mechanism 4.

[0075] The assembly stroke L3 of the snap mechanism 4 is the vertical distance from the end of the snap 42 away from the fixed plate 412 to the partition 1 when the button 44 is not pressed, and is also the maximum distance that the snap 42 can move in the reverse direction of the X-axis; the extension length L4 of the button 44 away from the end connected to the snap 42 extending from the fixed plate 412 is the vertical distance from the end of the button 44 away from the snap 42 to the fixed plate 412 when the button 44 is not pressed; preferably, L4>L3; when L4<L3, when the installer presses the button 44, the button 44 is easy to slip out of the first through hole 4121 in the reverse direction of the X-axis, resulting in increased assembly difficulty of the volute assembly 2, therefore, L4>L3, to ensure stable operation of the snap mechanism 4. Further, preferably, L4-L3≥3mm, so as to ensure that when the installer presses the button 44, the button 44 will not sink into the first through hole 4121 in the reverse direction of the X-axis, thereby avoiding the situation where the installer cannot touch the button 44.

[0076] Furthermore, combined with Figure 8As shown, the maximum compression distance L1 of the spring 43 is preferably greater than the maximum movement stroke L2 of the button 44, wherein the maximum movement stroke L2 of the button 44 is the vertical distance from the end of the button 44 away from the fixed plate 412 to the side of the fixed plate 412 facing the mounting plate 21; in this way, when L1 is less than L2, the spring 43 is easily damaged by the maximum compression when the installer presses the button 44.

[0077] Optionally, combined Figure 3 , Fig.10 As shown, a boss 32 is further provided on the top cover plate 3 , and the limiting hole 31 is arranged on the boss 32 .

[0078] The boss 32 is provided on the top cover plate 3, and can be protruding in a direction away from the volute 22 or in a direction toward the volute 22, and a limiting hole 31 is provided on the boss 32 for engaging with the spring buckle 42 to ensure the stability of the connection between the volute assembly 2 and the top cover plate 3. Since one end of the spring buckle 42 engaging in the limiting hole 31 is hook-shaped, after the spring buckle 42 engages in the limiting hole 31, the end of the spring buckle 42 engaging in the limiting hole 31 simultaneously abuts against the side of the boss 32 away from the volute 22.

[0079] Furthermore, the boss 32 and the top cover plate 3 may be fixedly connected (for example, integrally formed, welded, etc.), or detachably connected (for example, connected by fasteners) between the boss 32 and the top cover plate 3 .

[0080] Optionally, combined Figure 3 , Fig.10 As shown, the boss 32 is located on the side of the top cover plate 3 facing the volute assembly 2 .

[0081] The boss 32 is preferably raised from the top cover plate 3 toward the volute 22, so that the side of the boss 32 away from the volute 22 is a recessed structure, and the end of the spring buckle 42 that is inserted into the limiting hole 31 is located in the recessed structure; in this way, by providing the boss 32, on the one hand, the recessed structure on the side of the boss 32 away from the volute 22 can protect the end of the spring buckle 42 that is inserted into the limiting hole 31, and on the other hand, after the spring buckle 42 is upwardly inserted into the limiting hole 31, the spring buckle 42 will not protrude from the side of the top cover plate 3 away from the volute 22, thereby ensuring the flatness of the side of the top cover plate 3 away from the volute 22, so as to facilitate the assembly of the duct unit on the indoor wall.

[0082] Optionally, combined Fig.11 As shown, a connecting plate 33 is further provided on the top cover plate 3 , and the boss 32 is arranged on the connecting plate 33 .

[0083] A connecting plate 33 is provided between the boss 32 and the top cover plate 3, and the connecting plate 33 is connected to the top cover plate 3 on the side facing away from the volute 22, and is connected to the boss 32 on the side facing the volute 22; in this way, the boss 32 and the connecting plate 33 form a cavity for accommodating the spring buckle 42 to be inserted into one end of the limiting hole 31, so that the volute assembly 2 and the top cover plate 3 are connected through the boss 32 and the connecting plate 33; when the boss 32 and the top cover plate 3 are integrally formed, the top cover plate 3 needs to be stamped and blanked, which will destroy the sealing and integrity of the top cover plate 3. In this embodiment, the connecting plate 33 is provided to connect the boss 32 and the top cover plate 3, thereby ensuring the sealing and integrity of the top cover plate 3.

[0084] Optionally, combined Figure 6 , Figure 7 As shown, the buckle structure 5 includes a limit buckle 51; the limit buckle 51 is arranged on the mounting plate 21, and a limit slot 14 is provided at a position on the partition 1 corresponding to the limit buckle 51, and / or the limit buckle 51 is arranged on the partition 1, and a limit slot 14 is provided at a position on the mounting plate 21 corresponding to the limit buckle 51; and the limit buckle 51 is engaged with the limit slot 14.

[0085] The mounting plate 21 and the partition 1 are detachably connected via a snap-fit ​​structure 5. In the present embodiment, the mounting plate 21 may be provided with a limit snap-fit ​​51, and the partition 1 may be provided with a limit snap-fit ​​51; or the mounting plate 21 may be provided with a limit snap-fit ​​groove 14, and the partition 1 may be provided with a limit snap-fit ​​51; or the mounting plate 21 may be provided with a limit snap-fit ​​51 and a limit snap-fit ​​groove 14, and the partition 1 may also be provided with a limit snap-fit ​​51 and a limit snap-fit ​​groove 14; and the limit snap-fit ​​51 (limit snap-fit ​​groove 14) on the mounting plate 21 is snap-fitted with the corresponding limit snap-fit ​​groove 14 (limit snap-fit ​​51) on the partition 1 to ensure the stability of the volute assembly 2 when connected to the partition 1 and the convenience of disassembly and installation. Based on the snap fit between the spring buckle 42 and the limiting hole 31, the dimensions of the limiting slot 14 in the left-right direction and the up-down direction are larger than the corresponding dimensions of the limiting buckle 51, so that the limiting buckle 51 can be smoothly inserted into the limiting slot 14, so that the limiting buckle 51 has a certain amount of movable space in the limiting slot 14, so that the spring buckle 42 can be smoothly inserted into the limiting hole 31 upward. For ease of description, the following example is taken as an example that the mounting plate 21 is provided with a limiting buckle 51 and the partition 1 is provided with a limiting slot 14. After the limiting buckle 51 is inserted into the limiting slot 14, the partition 1 limits the limiting buckle 51 (motor assembly) through the groove wall of the limiting slot 14 to prevent the motor assembly from moving downward and forward and backward, so as to ensure that after the limiting buckle 51 is snap fit with the limiting slot 14, the spring buckle 42 can be smoothly inserted into the limiting hole 3 upward. 1, and based on the snap fit between the spring buckle 42 and the limiting hole 31, the snap fit between the limiting card slot 14 and the limiting card buckle 51, the stability of the volute assembly 2 in the duct machine is further improved; moreover, compared with the use of fasteners to connect the volute assembly 2 with the partition 1 and the top cover plate 3, the snap fit between the limiting card slot 14 and the limiting card buckle 51, and the snap fit between the spring buckle 42 and the limiting hole 31, greatly improve the convenience of disassembly and installation of the volute assembly 2 and the partition 1.

[0086] Optionally, combined Figure 6 , Figure 7 As shown, the buckle structure 5 also includes a positioning buckle 52; the positioning buckle 52 is arranged on the mounting plate 21, and a positioning slot 15 is provided at a position on the partition 1 corresponding to the positioning buckle 52, and / or the positioning buckle 52 is arranged on the partition 1, and a positioning slot 15 is provided at a position on the mounting plate 21 corresponding to the positioning buckle 52; and the positioning buckle 52 is engaged with the positioning slot 15.

[0087] The size of the positioning slot 15 in the up-down direction is larger than the size of the positioning buckle 52 in the up-down direction, so that the spring buckle 42 can be smoothly inserted into the limiting hole 31 upward; different from the above-mentioned limiting buckle 51 and limiting slot 14, the size of the positioning slot 15 in the left-right direction is equal to or slightly larger than the size of the positioning buckle 52 in the left-right direction. For the convenience of description, the following is an example of a positioning buckle 52 being provided on the mounting plate 21 and a positioning slot 15 being provided on the partition 1. After the positioning buckle 52 and the positioning slot 15 are engaged, the partition 1 is aligned with the positioning buckle through the groove wall of the positioning slot 15. 52 (motor assembly) plays a limiting and positioning role to prevent the motor assembly from moving downward, forward and backward, and left and right, and after the positioning buckle 52 is engaged with the positioning slot 15, the spring buckle 42 can be directly aligned with the limiting hole 31 when the button 44 is pressed, so that the spring buckle 42 can be directly engaged with the limiting hole 31 upward; and based on the engagement of the spring buckle 42 with the limiting hole 31 and the engagement of the limiting slot 14 with the limiting buckle 51, the engagement of the positioning buckle 52 with the positioning slot 15 further improves the stability of the volute assembly 2 in the duct machine.

[0088] Optionally, combined Fig.12 , Fig.13 As shown, a folded edge structure 16 is provided at the matching position between the limiting buckle 51 and the limiting slot 14 , and / or at the matching position between the positioning buckle 52 and the positioning slot 15 .

[0089] For ease of description, the following is an example in which a positioning buckle 52 and a limiting buckle 51 are provided on the mounting plate 21, and a positioning slot 15 and a limiting slot 14 are provided on the partition 1. A folding structure 16 is provided on the partition 1, and the folding structure 16 is located above the limiting buckle 51 and / or the positioning buckle 52. The thickness of the partition 1 at the folding structure 16 is greater than the thickness of the partition 1 at other places, wherein the thickness of the partition 1 is the size of the partition 1 in the front-to-back direction; in this way, the structural strength of the partition 1 at the snap-fitting part between the limiting buckle 51 and the limiting slot 14 and / or the snap-fitting part between the positioning buckle 52 and the positioning slot 15 is improved, thereby improving the stability of the volute assembly 2 when connected to the partition 1.

[0090] Optionally, combined Figure 1 , Figure 2 , Figure 6 , Fig. 9 , Fig.12 , Fig.16 As shown, the mounting plate 21 and the partition plate 1 are arranged parallel to each other and fit each other.

[0091] The mounting plate 21 is preferably arranged to fit closely with the partition 1 so that the contact area between the mounting plate 21 and the partition 1 is large enough to ensure the stability of the connection between the mounting plate 21 and the partition 1; specifically, the mounting plate 21 and the partition 1 are both plate-shaped, and the side surface of the mounting plate 21 facing the partition 1 is arranged parallel to the side surface of the partition 1 facing the mounting plate 21, so that after the mounting plate 21 is detachably connected to the partition 1, the mounting plate 21 and the partition 1 fit closely with each other.

[0092] Optionally, combined Figure 14-16 , Fig.18 As shown, a mounting hole 211 is provided at the lower end of the mounting plate 21, and a matching hole 113 matching the mounting hole 211 is provided at the lower end of the partition 1. The mounting plate 21 and the partition 1 are detachably connected at the mounting hole 211 and the matching hole 113 by fasteners.

[0093] The mounting plate 21 is provided with a mounting hole 211, and the partition 1 is provided with a matching hole 113 at a position corresponding to the mounting hole 211. The mounting plate 21 and the partition 1 are detachably connected by screwing fasteners (such as screws) into the mounting hole 211 and the matching hole 113. Further, the mounting hole 211 is preferably arranged at the lower end of the mounting plate 21 (that is, the mounting plate 21 is located at the bottom of the mounting plate 21). Fig.16 The mounting plate 21 and the partition 1 are connected to each other at the same time. ...

[0094] Optionally, combined Figure 16-Figure 20 As shown, the snap structure 5 includes a snap 53; the snap 53 is arranged at the upper end of the mounting plate 21, and a positioning groove 112 is provided at the upper end of the partition 1, and / or, a positioning groove 112 is provided at the upper end of the mounting plate 21, and the snap 53 is arranged at the upper end of the partition 1; and the snap 53 is snap-fitted with the positioning groove 112.

[0095] Based on the lower end of the mounting plate 21 and the lower end of the partition 1 being detachably connected by fasteners, the upper end of the mounting plate 21 (i.e. the mounting plate 21 is located at Fig.16The end in the positive direction of the middle Z axis) and the upper end of the partition 1 (that is, the end of the partition 1 located in the positive direction of the Z axis) are detachably connected by the snap fit between the clip 53 and the positioning groove 112; specifically, the mounting plate 21 is provided with a clip 53 and / or a positioning groove 112, the partition 1 is provided with a positioning groove 112 and / or a clip 53, and the clip 53 (positioning groove 112) on the mounting plate 21 corresponds to the positioning groove 112 (clip 53) on the partition 1; by providing the clip 53 and the positioning groove 112, the stability of the connection between the mounting plate 21 and the partition 1 is further guaranteed, and the disassembly and installation between the mounting plate 21 and the partition 1 are facilitated. Moreover, the buckle 53 and the positioning groove 112 are located above the mounting hole 211 and the matching hole 113 (i.e., the positive direction of the Z axis), which facilitates the disassembly and installation between the mounting plate 21 and the partition 1; specifically, a return air port (not shown in the figure) is provided on the chassis of the duct machine, and a bottom plate suitable for disassembly is provided in the return air port. After the bottom plate is removed from the chassis, the volute assembly 2 can be taken out from the fan cavity downward (i.e., in the reverse direction of the Z axis) through the return air port; when the mounting hole 211 and the matching hole 113 are arranged above the buckle 53 and the positioning groove 112 (i.e., the positive direction of the Z axis), the volute 22 and other components are easy to hinder maintenance personnel from making adjustments in the mounting hole 2 11 and the matching hole 113, and screwing the fasteners into the mounting hole 211 and the matching hole 113 is more complicated than the snap fit between the buckle 53 and the positioning groove 112. Such a setting will increase the difficulty of disassembly and installation between the mounting plate 21 and the partition 1; therefore, the setting of the buckle 53 and the positioning groove 112 above the mounting hole 211 and the matching hole 113 facilitates the assembly of the mounting plate 21 and the partition 1 at the lower end by screwing the fasteners into the mounting hole 211 and the matching hole 113, thereby improving the convenience of disassembly and installation of the volute 22.

[0096] Optionally, combined Figure 16-Figure 20 As shown, a positioning groove 112 is provided on the partition 1, and the buckle 53 is protruded on the side of the mounting plate 21 facing the partition 1, and the buckle 53 and the mounting plate 21 form a slot 24, and the angle between the slot wall of the slot 24 located on the mounting plate 21 and the slot wall of the slot 24 located on the buckle 53 is between ° and 0°.

[0097] The positioning groove 112 is provided on the partition 1, and is in the shape of a through hole penetrating the partition 1; after the mounting plate 21 is installed on the partition 1, the buckle 53 protruding on the side of the mounting plate 21 facing the partition 1 is inserted into the positioning groove 112 and extends to the side of the partition 1 away from the mounting plate 21, and the buckle 53 abuts against the lower groove wall 1122 of the positioning groove 112 (that is, the groove wall of the positioning groove 112 located in the opposite direction of the Z axis), so that the mounting plate 21 is hung on the partition 1. After the mounting plate 21 and the partition 1 are connected by fasteners, the partition 1 limits the mounting plate 21 to prevent the mounting plate 21 from being displaced in the vertical direction (that is, the Z axis direction), thereby ensuring the stability of the connection between the mounting plate 21 and the partition 1, that is, ensuring the stability of the connection between the volute assembly 2 and the partition 1.

[0098] Furthermore, the buckle 53 is a plate-like structure, and the angle between the buckle 53 and the mounting plate 21 is less than 0°, so that the upper side surface of the buckle 53 (that is, the side surface of the buckle 53 located in the positive direction of the Z axis) is inclined. When the buckle 53 is inserted into the positioning groove 112, the upper side surface of the buckle 53 can guide the buckle 53 to be inserted into the positioning groove 112; the lower side surface of the buckle 53 (that is, the side surface of the buckle 53 located in the opposite direction of the Z axis) and the side surface of the mounting plate 21 facing the partition 1 form a slot 24. After the buckle 53 is inserted into the positioning groove 112, the part of the partition 1 located at the positioning groove 112 is inserted into the slot 24. In this way, the partition 1 prevents the mounting plate 21 from moving forward and backward along the front-back direction (that is, Fig.16 The volute assembly 21 is provided with a plurality of mounting holes 211 and 113, and the mounting holes 211 and 113 are provided with a plurality of mounting holes 211 and 113. ... volute assembly 21 is provided with a plurality of mounting holes 211 and 113. The volute assembly 21 is provided with a plurality of mounting holes 211 and 113, and the volute assembly 21 is provided with a plurality of mounting holes 211 and 113.

[0099] Furthermore, the angle α between the groove wall of the slot 24 on the mounting plate 21 and the groove wall of the slot 24 on the buckle 53 satisfies °≤α≤0°, and the groove wall of the slot 24 on the buckle 53 is also the upper side of the buckle 53; when α is less than °, the angle between the upper side of the buckle 53 and the partition 1 is too small, making it difficult for the upper side of the buckle 53 to guide the buckle 53 to be inserted into the positioning groove 112, which is not conducive to the buckle 53 being smoothly inserted into the positioning groove 112; when α is greater than 0°, the angle between the lower side of the buckle 53 and the partition 1 is too large, making it difficult for the partition 1 to be inserted into the positioning groove 112. It hinders the movement of the mounting plate 21 in the front-to-back direction, resulting in an insufficiently firm connection between the mounting plate 21 and the partition 1; therefore, α preferably satisfies °≤α≤0°, to ensure that the upper side of the buckle 53 guides the buckle 53 to enter the positioning groove 112, so as to facilitate the disassembly and installation of the volute 22, and after the buckle 53 is inserted into the positioning groove 112, the partition 1 can limit the mounting plate 21, hindering the mounting plate 21 from moving toward or away from the partition 1, so as to enhance the stability of the connection between the mounting plate 21 and the partition 1.

[0100] Optionally, combined Figure 14-Figure 20 As shown, there is a gap between one end of the buckle 53 connected to the mounting plate 21 and the upper groove wall 1121 of the positioning groove 112 .

[0101] There is a gap between the end of the buckle 53 connected to the mounting plate 21 and the upper groove wall 1121 of the positioning groove 112 (that is, the groove wall of the positioning groove 112 located in the positive direction of the Z-axis), that is, after the buckle 53 is inserted into the positioning groove 112, the vertical distance between the upper groove wall 1121 and the lower groove wall 1122 of the positioning groove 112 is greater than the maximum vertical distance from the lower groove wall 1122 of the positioning groove 112 to the end of the buckle 53 connected to the mounting plate 21; in this way, the buckle 53 has sufficient space to move when it is inserted into the positioning groove 112, avoiding the situation where the vertical distance between the upper groove wall 1121 and the lower groove wall 1122 of the positioning groove 112 is too small, which hinders the buckle 53 from being inserted into the positioning groove 112, thereby facilitating the snap-fitting between the buckle 53 and the positioning groove 112.

[0102] Optionally, combined Figure 14-Figure 20 As shown, the gap between one end of the buckle 53 connected to the mounting plate 21 and the upper groove wall 1121 of the positioning groove 112 is between 2 mm and 4 mm.

[0103] The gap between the end of the buckle 53 connected to the mounting plate 21 and the upper groove wall 1121 of the positioning groove 112 (that is, the minimum distance between the buckle 53 and the upper groove wall 1121 of the positioning groove 112) h1 satisfies 2mm≤h1≤4mm; when h1 is greater than 4mm, the airflow blown from the volute 22 to the heat exchange cavity is easy to flow back to the fan cavity from the gap between the buckle 53 and the upper groove wall 1121 of the positioning groove 112, and air leakage occurs; when h1 is less than 2mm, the gap between the buckle 53 and the positioning groove The gap between the upper groove wall 1121 of 112 is too small, which makes it difficult to engage the buckle 53 with the positioning groove 112, resulting in increased difficulty in installation and disassembly between the mounting plate 21 and the partition 1; therefore, h1 preferably satisfies 2mm≤h1≤4mm, so as to achieve a balance between improving the convenience of installation and disassembly between the mounting plate 21 and the partition 1, and ensuring that the airflow blown from the volute 22 into the heat exchange chamber is difficult to flow back to the fan chamber from the gap between the buckle 53 and the upper groove wall 1121 of the positioning groove 112.

[0104] Optionally, combined Fig.17 , Figure 19-20 As shown, the vertical distance from the end of the buckle 53 connected to the mounting plate 21 to the position where the buckle 53 contacts the partition 1 is between 3 mm and 5 mm.

[0105] In this embodiment, after the buckle 53 is inserted into the positioning groove 112, the mounting plate 21 is hung on the partition 1, and the buckle 53 contacts the partition 1 at the lower groove wall 1122 of the positioning groove 112. Therefore, the position where the buckle 53 contacts the partition 1 refers to the lower groove wall 1122 of the positioning groove 112. The vertical distance from the end of the clip 53 connected to the mounting plate 21 (i.e., the lower end of the clip 53, which is also the end of the clip 53 located in the opposite direction of the Z axis) to the position where the clip 53 contacts the partition 1 is the vertical distance h2 from the lower end of the clip 53 to the lower groove wall 1122 of the positioning groove 112, and h2 satisfies 3mm≤h2≤5mm; when h2 is less than 3mm, the clip 53 is easy to fall out of the positioning groove 112, and when h2 is greater than 5mm, the installation stroke of the clip 53 into the positioning groove 112 is too long, which reduces the installation efficiency between the mounting plate 21 and the partition 1, and makes it difficult for the clip 53 to fall out of the positioning groove 112, making it inconvenient to disassemble between the mounting plate 21 and the partition 1; therefore, h2 preferably satisfies 3mm≤h2≤5mm, so that while improving the convenience of disassembly and installation between the partition 1 and the mounting plate 21, the clip 53 will not easily fall out of the positioning groove 112.

[0106] Optionally, combined Fig.16 , Fig. 20As shown, the partition 1 includes an integrally formed partition body 11 and a flange 12, and the mounting plate 21 is detachably connected to the partition body 11; an opening 11 for communicating with the air outlet of the volute 22 is provided on the partition body 11, and the flange 12 is arranged around the opening 11, and the flange 12 is folded in a direction away from the mounting plate 21.

[0107] The flange 12 of the partition 1 is annular and is arranged around the opening 11 on the partition body 11, and the flange 12 extends away from the end connected to the partition body 11 in the direction away from the mounting plate 21 (i.e., in the opposite direction of the X-axis), that is, the flange 12 extends in the direction of the heat exchanger of the air duct machine. In this way, the flange 12 can guide the airflow blown out from the volute 22 to prevent the airflow from diffusing when it flows to the heat exchanger through the opening 11 on the partition body 11, so that the airflow flows to the heat exchanger in a direction, ensuring that the airflow is fully in contact with the heat exchanger, thereby improving the heat exchange effect of the heat exchanger; and the design of the flange 12 The arrangement strengthens the structural strength of the partition 1, thereby improving the structural strength of the air duct machine housing; in addition, the arrangement of the flange 12 allows the flange 12 to guide the water flow when the heat exchanger is flushed with a water gun, so that the water flow is directed to the heat exchanger, thereby improving the working efficiency of the heat exchange flushing; and because the flange 12 extends a certain distance toward the heat exchange chamber of the air duct machine, when the heat exchanger is flushed with a water gun, the flange 12 can block the water flow returning from the heat exchange chamber of the air duct machine to the fan chamber to a certain extent, so as to prevent the water flow from splashing into the room from the opening 11 and affecting the user experience.

[0108] By providing a flange 12, the airflow blown out from the volute 22 is guided to prevent the airflow from diffusing when flowing to the heat exchanger through the opening 11 on the partition body 11, so that the airflow can flow to the heat exchanger in a direction, ensuring that the airflow is in full contact with the heat exchanger, thereby improving the heat exchange effect of the heat exchanger; and the provision of the flange 12 strengthens the structural strength of the partition 1, thereby improving the structural strength of the air duct machine housing.

[0109] Optionally, combined Fig.16 , Fig. 20 As shown, the vertical distance from the end of the flange 12 away from the partition body 11 to the partition body 11 is between 3 mm and 5 mm.

[0110] The protruding height h3 of the flange 12 on the partition body 11 (i.e., the dimension of the flange 12 in the X-axis direction) satisfies 3mm≤h3≤5mm; when h3 is less than 3mm, the guiding effect on the airflow is limited, and when h3 is greater than 5mm, the overall production difficulty of the partition 1 will increase; therefore, h3 preferably satisfies 3mm≤h3≤5mm to ensure the guiding effect of the flange 12 on the airflow without increasing the production difficulty of the partition 1.

[0111] Optionally, combined Figure 1-Figure 20As shown, the partition 1 further includes a folded edge 13 which is arranged on the partition body 11 and is integrally formed with the partition body 11 , and the folded edge 13 is located at both ends of the partition body 11 in the length direction and / or the width direction of the partition body 11 .

[0112] The folded edge 13 of the partition 1 can be arranged in the length direction of the partition body 11 (i.e. Fig.14 The two ends in the Y-axis direction can also be arranged in the width direction of the partition body 11 (i.e. Fig.14 The two ends of the partition body 11 in the Z-axis direction may also be provided at both ends in the length direction of the partition body 11 and both ends in the width direction of the partition body 11. A folded edge 13 away from the end connected to the partition body 11 may extend in a direction away from the mounting plate 21, or may extend in a direction toward the mounting plate 21, and the folded edge 13 is perpendicular to the partition body 11, so that the folded edges 13 at both ends in the length direction of the partition body 11 are respectively fitted with the left and right plates of the air duct machine, or the folded edges 13 at both ends in the width direction of the partition body 11 are respectively fitted with the top cover plate 3 and the bottom plate of the air duct machine, thereby improving the stability of the partition 1 in the shell of the air duct machine and further improving the structural strength of the shell of the air duct machine; further, screw holes are provided on the folded edge 13 and the corresponding panel of the air duct machine, which are used for the detachable connection between the folded edge 13 and the corresponding panel of the air duct machine, so as to further improve the stability of the partition 1 in the shell of the air duct machine and the structural strength of the shell of the air duct machine.

[0113] Furthermore, similar to the folding edge 13 provided on the partition 1, the folding edge 13 structure can also be provided at both ends of the mounting plate 21 in the Y-axis direction and / or the Z-axis direction to fit with the corresponding panel of the duct machine, thereby improving the stability of the volute assembly 2 in the duct machine casing.

[0114] Optionally, combined Figure 1-Figure 15 As shown, the fold edge 13 is folded away from the mounting plate 21 .
