Thereby, the motor ears 222 in the motor 22 are supported and connected to the side of the inner end ring 322 in the inner bracket 32 away from the cylindrical portion 321, and the motor body 221 is embedded inside the cylindrical portion 321 by the inner end ring 322, so that the motor 22 and the inner bracket 32 have high compactness, the assembled whole thickness of the motor 22 and the inner bracket 32 is reduced, and the motor body 221 can be protected by the cylindrical portion 321, thereby improving the service life of the motor 22.

It should be noted that the connection form when the motor ears 222 are connected to the inner end ring 322 is not limited, and may be, for example, a detachable connection, such as a connection by bolts or screws, so that the motor 22 is convenient to disassemble and assemble, and has high installation stability, or may be, for example, a non-detachable connection, such as a connection by welding, so that the installation stability of the motor 22 may be higher. The manufacturing method of the inner bracket 32 is not limited, and may be, for example, an integral piece, wherein the inner end ring 322 and the outer end ring 323 may be manufactured by flanging the two axial ends of the cylindrical portion 321 outward, and may be, for example, a separate piece, and for example, the inner end ring 322 and the outer end ring 323 which are separately processed may be assembled to the two axial ends of the cylindrical portion 321, respectively, and are combined together, which will not be described herein again.

In some embodiments, as shown in fig. 4 and 5, the air duct member 1 may include a support portion 12 extending from the mounting opening 111 into the volute portion 11, an extending end of the support portion 12 may be stopped at a side of the inner end ring 322 away from the motor ear 222 (i.e., an inner side of the inner end ring 322, a front side as shown in fig. 5), and the extending end of the support portion 12 may be elastically deformed in a direction perpendicular to an axis of the motor 22. Accordingly, the support portion 12 is stopped at a side of the inner end ring 322 away from the motor 22, so that the inner bracket 32 is prevented from falling off due to reverse movement (movement in a backward-forward direction as indicated by an arrow in fig. 5), and the structural stability of the air duct member 1 and the inner bracket 32 can be improved.

For example, in the specific example shown in fig. 5, the support portion 12 may be provided in a snap-fit manner having elastic deformation, the slope 121 is formed on a side of the support portion 12 facing the inner end ring 322, and the outermost diameter D of the inner end ring 322 is larger than the distance L between the ends of the support portion 12 which are oppositely provided, when the inner bracket 32 is fitted from outside to inside (from front to back as shown in fig. 5) from the mounting opening 111, the edge of the inner end ring 322 of the inner bracket 32 acts on the slope 121 of the support portion 12, the end of the support portion 12 may be inclined in a direction away from the inner end ring 322 first, after the inner end ring 322 is fitted in place, the end of the support portion 12 may be restored to its original shape, and the extended end of the support portion 12 may be stopped at a side of the inner end ring 322 close to the outer end ring 323 (from the front side of the inner end ring 322 as shown in fig. 5), thereby preventing the inner bracket 32 from moving in a reverse direction (from moving, thereby improving the reliability of the connection between the air duct member 1 and the bracket assembly 3.

In some embodiments, as shown in fig. 6, the inner end ring 322 and the cylindrical portion 321 may have a wire passing opening 324 thereon, and the air duct component 100 may further include a wire pressing plate 4 detachably connected to the volute portion 11.

In addition, when the tension disc 4 is detachably fixed with the volute part 11, the tension disc can be fixed in the form of bolts, screws or buckles, for example, so that the tension disc 4 is convenient to mount, and the mounting time of the tension disc 4 can be saved.

In some embodiments, as shown in fig. 7, the outer end ring 323 and the outer bracket 31 can be positioned and engaged by the positioning structure C and fixedly connected by welding and/or the first connecting member 33. Therefore, the outer end ring 323 and the outer bracket 31 are conveniently positioned, the assembly efficiency is high, and the structural stability can be higher when the outer end ring 323 and the outer bracket 31 are fixedly connected through welding or the first connecting piece 33.

It should be noted that the type of the first connecting element 33 is not limited, and for example, the first connecting element may be a threaded connecting element (e.g., a bolt), and the description thereof is omitted.

For example, in the specific example shown in fig. 7, the positioning structure C may include a positioning protrusion 3112 and a positioning hole 3231, wherein the positioning protrusion 3112 is disposed on the outer bracket 31, and the positioning hole 3231 is disposed on the outer ring 323 and is in positioning fit with the positioning protrusion 3112, when the positioning structure is installed, the positioning protrusion 3112 may be first in fitting position with the positioning hole 3231, and then the joint between the outer ring 323 and the outer bracket 31 is welded or fixedly connected by using the first connecting element 33, so that the positioning between the outer bracket 31 and the outer ring 323 is convenient and the structural stability is good.

In some embodiments, as shown in fig. 9 and 10, the volute section 11 may include: the volute casing enclosing plate 112, the first volute casing cover plate 113 and the second volute casing cover plate 114 are arranged oppositely, the volute casing enclosing plate 112 is clamped between the first volute casing cover plate 113 and the second volute casing cover plate 114, with reference to fig. 5, the wind wheel 21 can be a centrifugal wind wheel 21a, an air inlet 1131 is formed on the first volute casing cover plate 113, an air outlet 1121 is formed on the volute casing enclosing plate 112, and the mounting opening 111 is formed on the second volute casing cover plate 114. Therefore, the direction of the air outlet can be changed by the centrifugal wind wheel 21a, for example, the direction indicated by the arrow F1 in fig. 2 is the air inlet direction of the air inlet 1131, and the direction indicated by the arrow F2 is the air outlet direction of the air outlet 1121.

For example, in a specific example, as shown in fig. 9 and 10, the air inlet 1131 is formed on the first volute cover plate 113, and in conjunction with fig. 5, the air outlet 1121 is formed on the volute surrounding plate 112, and further, the fan assembly 2 is disposed in the volute section 11, the wind wheel 21 in the fan assembly 2 may be a centrifugal wind wheel 21a, the axial direction of the centrifugal wind wheel 21a is perpendicular to the first volute cover plate 113, when the centrifugal wind wheel 21a rotates, wind can enter the volute section 11 from the wind inlet 1131, and the wind inlet direction is perpendicular to the first volute cover plate 113, then, by the action of the centrifugal wind wheel 21a, the airflow perpendicular to the direction of the first volute cover plate 113 is changed to be parallel to the directions of the first volute cover plate 113 and the second volute cover plate 114 (although it should be noted that the first volute cover plate 113 and the second volute cover plate 114 are not limited to be arranged in parallel), and then the air is discharged from the air outlet 1121 in the volute enclosure plate 112. Therefore, the direction of the air outlet can be changed by the centrifugal wind wheel 21a, for example, the direction indicated by the arrow F1 in fig. 2 is the air inlet direction of the air inlet 1131, and the direction indicated by the arrow F2 is the air outlet direction of the air outlet 1121. In addition, the centrifugal wind wheel 21a occupies a smaller dimension in the axial direction (e.g., the front-rear direction shown in fig. 2), so that the fan assembly 2 occupies a smaller space on the premise of satisfying the air supply effect, and the design of the air conditioner 1000 can be optimized, so that the overall thickness direction (e.g., the front-rear direction shown in fig. 2) of the air conditioner 1000 is thinner.

In some embodiments, as shown in fig. 7 and 8, external bolster 31 may include: with reference to fig. 9, the first plate 311 is disposed on a side of the second volute cover plate 114 away from the first volute cover plate 113, two second plates 312 are disposed on two sides of the first plate 311, a central connection line L1 of the two second plates 312 is perpendicular to the air outlet direction F2 of the air outlet 1121, one end 3121 of the second plates 312 is connected to the first plate 311, and the other end 3122 of the second plates 312 extends to the first volute cover plate 113 and is adapted to be fixed to the sheet metal member 200a in the air conditioner 1000 (as shown in fig. 1).

Thus, the shape of the first plate 311 and the two second plates 312 in the outer bracket 31 is substantially C-shaped, wherein the first plate 311 is close to the direction of the second volute cover plate 114, and one ends 3121 of the two second plates 312 are respectively connected to both sides of the first plate 311. The other ends 3122 of the two second plates 312 extend toward the first plates 311 on the opposite sides, and the extending ends of the second plates 312 can be connected to the sheet metal part 200a (as shown in fig. 1) in the air conditioner 1000, so that the outer bracket 31 is firmly fixed and has high stability.

For example, in a specific example, as shown in fig. 7, the other end 3122 of the second plate 312 may have a burring portion 31221, the burring portion 31221 is formed with a first connection hole 312211, the first volute cover 113 is formed with a second connection hole 1132 opposite to the first connection hole 312211, and in connection with fig. 10, the burring portion 31221 and the first volute cover 113 are collectively fixed to the sheet metal member 200a inside the air conditioner 1000 by the second connection member 5 penetrating through the first connection hole 312211 and the second connection hole 1132 (as shown in fig. 1). Therefore, the outer bracket 31 and the first volute cover plate 113 can be fixed simultaneously through the second connector 5, so that the number of the second connectors 5 can be reduced, the installation cost can be saved, and the air duct component 100 is compact in structure and high in stability.

It should be noted that the type of the second connecting member 5 is not limited, and for example, the second connecting member may be a threaded connecting member (e.g., a bolt, a screw), and the like, which is not described herein again.

In some embodiments, as shown in fig. 7 and 8, the second volute cover plate 114 may have a locating catch 1141 thereon, and the first plate 311 may be located to mate with the locating catch 1141. That is, the second volute cover plate 114 and the first plate 311 may be cooperatively positioned by a positioning catch 1141 on the second volute cover plate 114. Thus, the second volute cover plate 114 is connected to the first plate 311 in a simple and effective manner, so that the assembling efficiency can be improved.

For example, in one specific example, as shown in fig. 7 and 8, a plurality of spaced-apart positioning tabs 1141 are formed on the second volute cover plate 114, and a plurality of positioning tab holes 3111 are formed on the first plate 311 opposite to the plurality of positioning tabs 1141. When the second volute cover plate 114 is positioned and matched with the first plate 311, the snap fit can be realized by the snap in the second volute cover plate 114 passing through the positioning snap hole 3111 in the first plate 311. Therefore, the second volute cover plate 114 and the first plate 311 can be fixedly connected simply and effectively through the matching of the positioning buckle 1141 and the positioning buckle hole 3111, and therefore the assembly efficiency can be improved.

It should be noted that, the second volute cover plate 114 and the first plate 311 may include, but are not limited to, being connected in a form of a positioning buckle 1141, and may also be fixedly connected in a form of a threaded connector, and may further be connected in two different connection forms, i.e., a buckle and a threaded connector, as long as the second volute cover plate 114 and the first plate 311 can be fixedly connected, which is not described herein again.

In some embodiments, as shown in fig. 4, first volute cover plate 113 and volute closure plate 112 may be a unitary piece, and in conjunction with fig. 9, second volute cover plate 114 and volute closure plate 112 may be removably connected by at least one of a snap-fit arrangement 115 and a third connector 116. That is to say, the second volute cover plate 114 and the volute enclosing plate 112 may be connected only by the fastening structure 115, or may be connected only by the third connecting member 116, or may be connected by the fastening structure 115 and the third connecting member 116, so that the second volute cover plate 114 is convenient to mount and has high reliability, and further, the assembly efficiency and the structural stability may be improved, meanwhile, when the second volute cover plate 114 and the volute enclosing plate 112 are detachably connected, for example, when after-sales service personnel need to maintain or replace, for example, the wind wheel 21, the motor 22, and the like in the fan assembly 2 in the volute portion 11, only part of the assemblies need to be removed, for example, only the second volute cover plate 114 and the bracket assembly 3 need to be removed, and thus, the fan assembly 2 may be maintained or replaced without removing the whole air duct assembly 100, and further, the after-sales work efficiency is improved.
