[0073] Next, in combination withFigures 1 to 6 The air handling device according to the embodiments of the present disclosure will be described.

[0074] Here, for the convenience of description, three mutually orthogonal directions are set as the X direction, the Y direction, and the Z direction. One side of the X direction is set as X1, the other side of the X direction is set as X2, one side of the Y direction is set as Y1, the other side of the Y direction is set as Y2, one side of the Z direction is set as Z1, and the other side of the Z direction is set as Z2.

[0075] (Overall structure of the air handling device)

[0076] As Figure 1 and Figure 2 shown, the air handling device 1 includes a fan assembly 10. The fan assembly 10 is configured to suck air into the interior of the air handling device 1 and blow out the air that has been processed by the air handling device 1 (such as dehumidified, heat exchanged, purified, etc.) to the exterior of the air handling device 1.

[0077] Here, as Figure 1 and Figure 2 shown, the air handling device 1 is a total heat exchanger, including a housing KT. The housing KT is made of, for example, a metal material and has a top plate, a bottom plate opposite to the top plate, and side plates extending from the periphery of the top plate to the periphery of the bottom plate (the top plate and the bottom plate may be formed separately from the side plates or integrally with the side plates). And, a fresh air inlet JF, an exhaust air outlet PF, a return air inlet HF, and a supply air outlet SF are provided on the side plates of the housing KT. Inside the housing KT, there are formed: a supply air path from the fresh air inlet JF to the supply air outlet SF; and an exhaust air path from the return air inlet HF to the exhaust air outlet PF. An internal circulation path from the return air inlet HF to the supply air outlet SF may also be formed.

[0078] In addition, as Figure 2 shown, a total heat exchange core assembly is provided inside the housing KT. The total heat exchange core assembly includes a total heat exchange core HX. The total heat exchange core HX is fixedly arranged inside the housing KT through guide rails. Filter card slots may also be integrally provided on the guide rails for fixing filters. At least one of the bottom plate and the top plate of the housing KT is provided with a maintenance opening through which the total heat exchange core HX can enter and exit, and a maintenance cover for opening and closing the maintenance opening. The total heat exchange core HX has: a first air flow channel that forms a part of the supply air path; and a second air flow channel that forms a part of the exhaust air path. And, the air flow flowing through the first air flow channel can exchange heat with the air flow flowing through the second air flow channel.

[0079] In addition, as Figure 2As shown, the fan assembly 10 is disposed within the housing KT and includes: a fan assembly disposed in the air supply path; and a fan assembly disposed in the air exhaust path. The fan assembly 10 can be fixed to the top plate of the housing KT or the bottom plate of the housing KT. The air handling device 1 can be installed upright or upside down according to the actual installation requirements.

[0080] In addition, when the air handling device 1 performs air treatment on an object space such as a room, through the operation of the fan assembly 10, outdoor air can be introduced from the fresh air inlet JF into the air supply path within the housing KT and blown out from the air supply outlet SF into the room, and indoor air can be introduced from the return air inlet HF into the air exhaust path within the housing KT and blown out from the air exhaust outlet PF to the outside, that is, indoor and outdoor air exchange is achieved; or the air within the room can be introduced from the return air inlet HF into the housing KT through the operation of the fan assembly disposed in the air supply path and blown out from the air supply outlet SF into the room, that is, internal circulation is achieved.

[0081] Thus, the outdoor air and the indoor air form a cross-flow in the total heat exchange core HX, and temperature exchange and water vapor exchange occur between them.

[0082] In addition, an ion generating device for purifying the air in the air supply path can be disposed at a position close to the air supply outlet SF in the air supply path.

[0083] (Structure of the fan assembly)

[0084] As Figure 3 and Figure 4 shown, the fan assembly 10 includes: a motor 111; a motor bracket 112 for supporting the motor 111; and a centrifugal fan having an impeller 12 and a volute 113. The impeller 12 is driven by the motor 111, the volute 113 surrounds the impeller 12, and is fixedly connected to the centrifugal fan with the motor bracket 112.

[0085] Here, as Figure 3 shown, the motor 111 and the motor bracket 112 for the centrifugal fan are disposed on one side of the volute 113. In order to cooperate with the thinness of the whole machine and reduce the overall height of the centrifugal fan assembly 10, a part of the motor 111 and the motor bracket 112 is disposed inside the air suction port of the volute 113. Alternatively, the motor 111 and the motor bracket 112 can be entirely exposed relative to the volute 113. And, as Figure 4 and Figure 5 shown, the motor 111 is, for example, a DC motor and has a motor main body 1110 and a motor shaft 1111. The motor main body 1110 is fixed to the motor bracket 112 for the centrifugal fan, the motor shaft 1111 can rotate relative to the motor main body 1110, and is connected to the impeller 12 to drive the impeller 12 to rotate.

[0086] In addition, asFigure 3 As shown, the centrifugal fan is disposed on the upper end side of the motor bracket 112 (specifically, the upper end side of the following housing portion SN).

[0087] In addition, the impeller 12 has a disc-shaped portion and a plurality of blades arranged circumferentially on the disc-shaped portion, and the plurality of blades surround to form a cylindrical portion. The center of the disc-shaped portion has a shaft hole for connecting the motor shaft of the motor 111 thereto. One side in the axial direction of the motor bracket 112 is close to the disc-shaped portion, so as to reduce the overall height of the fan assembly 10.

[0088] In addition, as Figure 3 shown, the volute 113 surrounds the impeller 12 and has a volute bottom plate 1131 and a volute cover 1132. The volute bottom plate 1131 is fixedly connected to the bracket main body 1121 of the motor bracket 112. The volute cover 1132 and the volute bottom plate 1131 cover the impeller 12 from both sides in the axial direction of the impeller 12 and together enclose an air duct. And, the volute cover 1132 has: a top plate portion that faces the volute bottom plate 1131; and a side plate portion that extends from the top plate portion toward the volute bottom plate 1131 and whose front end is connected to the volute bottom plate 1131. An air suction port for sucking air is provided at a substantially central position of the volute bottom plate 1131 and the top plate portion of the volute cover 1132, and the air suction port is surrounded by a wind guiding ring provided on the volute bottom plate 1131 and the top plate portion of the volute cover 1132. The wind guiding ring is formed by making the inner diameter side edge thereof protrude obliquely or bendingly into the interior of the volute 113 and is opposed to the impeller 12 with a gap in the axial direction. And, a blowout port for blowing out air is formed on the side plate portion of the volute cover 1132. When the centrifugal fan operates, air flow is sucked into the air duct formed by the volute 113 from the air suction port of the volute bottom plate 1131 and the air suction port of the top plate portion of the volute cover 1132, and is blown out from the blowout port of the side plate portion of the volute cover 1132 after being pressurized.

[0089] In addition, although not shown, a fixing structure for cooperating with the following fixing post GD of the motor bracket 112 is provided on the volute bottom plate 1131. Specifically, it can be a hole groove. The fixing post GD is snap-fitted into the hole groove and fixed by screws. And, when a hole groove is provided on the volute bottom plate 1131, it is preferable that the hole groove is located between the edge of the air suction port on the volute bottom plate 1131 and the outer edge of the volute bottom plate 1131 (for example, provided within the radial width range of the wind guiding ring). Thus, both the fixed connection between the volute 113 and the motor bracket 112 can be ensured, and the stability of the fan assembly 10 can also be ensured. And, a washer can also be provided in the hole groove.

[0090] In addition, the material of the volute 113 can be any one of a foaming material, a resin material, and a metal material. Thus, the volute 113 can be easily manufactured. And, wire grooves, wire clips, etc. (not shown) can also be formed on the surface of the volute 113 for wires, etc. to pass through.

[0091] (Structure of the bracket main body)

[0092] As Figures 4 to 6 shown, the bracket main body 1121 includes: a storage portion SN, which forms a storage space SP for accommodating the motor 111, and the impeller 12 of the centrifugal fan driven by the motor 111 is on the side of the motor 111 in the axial direction (in the illustrated example, it is the Z2 direction side), and the volute 113 of the centrifugal fan with an air inlet formed in the middle is adjacent to the storage portion SN on the Z2 direction side; and a base portion DZ, which is connected to the storage portion SN on the other side of the motor 111 in the axial direction (in the illustrated example, it is the Z1 direction side), and has an annular main body that extends from the connection portion with the storage portion SN toward the outer peripheral side.

[0093] In addition, the bracket main body 1121 is an integrally formed resin part, whereby lightweight can be achieved, the number of components can be reduced, and assembly can be simplified.

[0094] Here, as Figure 5 shown, there is a gap between the motor main body 1110 of the motor 111 and the inner side wall of the storage portion SN. The gap can prevent the motor 111 from colliding with the bracket main body 1121 when vibrating and generating noise, and can also be used for heat dissipation to ensure the safe use of the motor 111 and guarantee the life of the motor 111.

[0095] In addition, as Figures 4 to 6 shown, the storage portion SN is generally in a cylindrical shape extending along the axial direction of the motor 111. An opening is formed on the side of the storage portion SN close to the centrifugal fan, and the motor 111 is inserted and removed through this opening. When the motor 111 is placed in the storage portion SN, at least a part of the motor main body 1110 is located in the cylindrical storage portion SN. A part of the circumferential direction of the storage portion SN is cut off to form a notch QK, which extends from one end of the storage portion SN in the axial direction of the motor 111 (in the illustrated example, it is the end on the Z2 direction side) to the other end (in the illustrated example, it is the end on the Z1 direction side). By providing the notch QK, the nameplate of the motor 111 can be exposed, which is convenient for identifying the type and model of the motor 111 during maintenance, and the notch QK can also be used for heat dissipation of the motor 111, improving the safety of the motor 111 and further improving the overall performance of the machine. And the notch QK can also be used for heat dissipation.

[0096] In addition, as Figure 4 and Figure 5As shown, the base portion DZ is provided with a wire groove GX. The wire groove GX extends from the central side of the base portion DZ to the outer peripheral edge of the base portion DZ. The circumferential position of the wire groove GX is substantially the same as the notch QK of the storage portion SN, and the wire groove GX opens to the side in the axial direction of the motor 111 (the Z2 direction side in the illustrated example) and communicates with the notch QK of the storage portion SN. And preferably, a wire pressing structure is formed in the wire groove GX. Specifically, preferably, one or more wire pressing structures are provided in the extending direction of the wire groove GX. And in the case of providing a plurality of wire pressing structures, as Figure 4 shown, the wire pressing structures can be staggeredly arranged on both sides of the wire groove GX, which can further prevent the wire from coming out of the wire groove GX. And preferably, on the air flow path, the wire groove GX is arranged on the downstream side of the air flow (the leeward side of the bracket main body 1121 facing away from the total heat exchange core HX), which can prevent the occurrence of turbulence in the wire groove GX, improve the air flow and reduce the pressure loss.

[0097] In addition, as Figure 2 shown, the fan assembly 10 is arranged such that the wire groove GX in the motor bracket 112 faces away from the heat exchange core body of the total heat exchange core HX and faces the side of the air outlet PF or the air supply port SF, so that the wiring of the motor assembly 11 can be conveniently carried out through the inspection port, and the interference of the air flow on the wiring in the wire groove can be avoided.

[0098] In addition, as Figures 4 to 6 shown, the bracket main body 1121 further includes fixing columns GD, and the fixing columns GD extend from the annular main body of the base portion DZ to the side in the axial direction of the motor 111. Specifically, the above-mentioned fixing columns GD are arranged on the outer peripheral edge of the base portion DZ, and the outer diameter gradually decreases from the other side in the axial direction of the motor 111 to one side (formed as a stepped column in the illustrated example, including a large diameter portion and a small diameter portion smaller than the large diameter portion, but not limited thereto), and a plurality of them are arranged at intervals in the circumferential direction (preferably arranged at equal intervals). And the end portion of the above-mentioned fixing column GD on the side in the axial direction of the motor 111 (the end portion on the Z2 direction side in the illustrated example) is connected to the volute 113 (the volute bottom plate 1131 thereof) by a connecting member such as a screw.

[0099] In addition, as Figure 4 and Figure 5 shown, a fixing portion DWB is formed on the upper end side of the storage portion SN of the motor bracket 112, and the fixing portion DWB has a first fixing portion DWBA for installing and fixing a gasket 1122 described later and a second fixing portion DWBB for installing and fixing the motor 111 described later.

[0100] The above-mentioned first fixing part DWBA and second fixing part DWBB are provided in groups, and multiple groups are provided at equal intervals in the circumferential direction on the upper end side of the storage part SN. By providing the fixing part DWB in multiple groups, the positioning accuracy when installing the gasket 1122 and the motor 111 can be improved, and the fixing strength can also be improved.

[0101] Moreover, the above-mentioned first fixing part DWBA and second fixing part DWBB are formed in the form of threaded holes, and the gasket 1122, the motor 111 and the motor bracket 112 can be fixedly connected by connecting parts such as screws.

[0102] In addition, as Figure 4 and Figure 5 shown, a plurality of heat dissipation holes SRK are also provided on the outer periphery of the base part DZ of the motor bracket 112. The plurality of heat dissipation holes SRK are in the form of through holes penetrating the base part DZ, and are provided at equal intervals in the circumferential direction on the outer periphery of the base part DZ. By providing the plurality of heat dissipation holes SRK, the heat generated by the motor 111 during operation can be appropriately dissipated to the outside, thereby further improving the operating performance of the motor 111.

[0103] (Structure of the motor and the gasket)

[0104] As Figure 5 shown, a plurality of fixing feet 1112 arranged at equal intervals in the circumferential direction are formed on the outer periphery of the motor 111 of the present disclosure. The plurality of fixing feet 1112 extend radially outward from the outer periphery of the motor 111 in a direction orthogonal to the axial direction.

[0105] In addition, the plurality of fixing feet 1112 can be provided on the upper end side of the outer peripheral surface of the motor 111, or at the middle position of the outer peripheral surface of the motor 111, or at the lower end side of the outer peripheral surface of the motor 111, as long as the plurality of fixing feet 1112 are aligned in a direction orthogonal to the axial direction.

[0106] Buffer pads HCD are respectively held in the plurality of fixing feet 1112. The buffer pads HCD are substantially cylindrical, and through holes are formed in the buffer pads HCD. The fixing feet 1112 of the motor 111 and the motor bracket 112 are fixedly connected through the buffer pads HCD by connecting parts such as screws. At this time, the fixing feet 1112 of the motor 111 are in contact with the upper surface of the storage part SN of the motor bracket 112 with the gasket 1122 therebetween.

[0107] The buffer pads HCD are made of materials that can be elastically deformed. Through the buffer pads HCD, the vibration transmitted from the motor 111 to the motor bracket 112 during the operation of the motor 111 can be weakened, thereby reducing the vibration of the entire device and reducing noise.

[0108] In addition, as Figure 5 shown, the gasket 1122 of the motor mounting assembly 112 of the present disclosure is substantially circular in shape, and a through hole for the motor body 1111 of the motor 111 to pass through is provided in the gasket 1122. The portion of the motor 111 below the fixed feet 1112 in the height direction (Z direction) passes through the through hole of the gasket 1122 and is received in the receiving space SP of the receiving portion SN.

[0109] In addition, the gasket 1122 mainly includes a main body portion and a mounting portion. A first fixing hole GDKA for cooperating with the first fixing portion DWBA of the motor bracket 112 is formed on the main body portion, and a second fixing hole GDKB for cooperating with the second fixing portion DWBB of the motor bracket 112 is formed on the mounting portion.

[0110] Corresponding to the first fixing portion DWBA and the second fixing portion DWBB, a plurality of groups of the first fixing holes GDKA and the second fixing holes GDKB are provided at equal intervals along the circumferential direction of the gasket 1122.

[0111] In addition, as Figure 5 shown, an inward flange NFB extending from the inner peripheral edge of the gasket 1122 toward one side in the axial direction of the motor 111 is formed on the radially inner side of the gasket 1122, and an outward flange WFB extending from the outer peripheral edge of the gasket 1122 toward one side in the axial direction of the motor 111 is formed on the radially outer side of the gasket 1122.

[0112] By providing the inward flange NFB, on the one hand, the structural strength of the gasket 1122 can be improved, and on the other hand, the gasket 1122 can be abutted against the outer surface of the motor 111 through the inward flange NFB, so that when the motor 111 is installed, the sharp inner edge of the gasket 1122 can be prevented from scratching the motor 111, the service life of the motor can be extended, and the operating performance of the motor can be improved.

[0113] By providing the outward flange WFB, the gasket 1122 can hold the fixed feet 1112 of the motor 111 through the card slot formed by the inward flange NFB and the outward flange WFB, which can facilitate the positioning of the fixed feet 1112 during installation and can also prevent the fixed feet 1112 from being displaced due to vibration during use, so that the motor 111 can be fixed more ideally.

[0114] (Fixing method of motor and motor bracket)

[0115] As described above, a plurality of fixing feet 1112 are formed on the motor 111, a plurality of fixing holes GDK are formed in the gasket 1122, and a plurality of fixing portions DWB are formed in the motor bracket 112. The fixing feet 1112 of the motor 111, the fixing holes GDK of the gasket 1122, and the fixing portions DWB of the motor bracket 112 are arranged in a corresponding manner to each other, and are fixedly connected by means of screw fastening.

[0116] When the motor 111 is to be mounted on the motor bracket 112, first, the first fixing hole GDKA of the gasket 1122 is aligned with the first fixing portion DWBA of the motor bracket 112, and the gasket 1122 and the motor bracket 112 are fixedly connected by a connecting member such as a screw.

[0117] In addition, the fixing holes GDK of the gasket 1122 and the fixing portions DWB of the motor bracket 112 are arranged such that when the first fixing hole GDKA is aligned with the first fixing portion DWBA, the second fixing hole GDKB is also aligned with the second fixing portion DWBB. At this time, the through hole in the fixing feet 1112 of the motor 111 is aligned with the second fixing hole GDKB and the second fixing portion DWBB, and the motor 111 is fixedly connected to the motor bracket 112 with the gasket 1122 interposed therebetween by a connecting member such as a screw.

[0118] (Fixing method of the fan assembly and the motor bracket)

[0119] As described above, a plurality of fixing posts GD are provided on the outer peripheral edge of the base portion DZ of the motor bracket 112, and as Figure 3 shown, a plurality of volute fixing portions GB that cooperate with the plurality of fixing posts GD are formed on the volute bottom plate 1222 of the volute 113 of the centrifugal fan 12. In this example, the plurality of volute fixing portions GB are formed in the form of through holes, and internal threads are formed in the fixing posts GD. Thus, the fixing posts GD are connected to the volute 113 (the volute bottom plate 1222 thereof) via the volute fixing portions GB by a connecting member such as a screw, and further the volute 113 and the motor bracket 112 are fixedly connected.

[0120] In addition, in addition to forming the volute fixing portions GB in the form of through holes, the volute fixing portions GB can also be formed in the form of receiving grooves that are recessed toward the upper end (the Z2 direction side), and through holes are formed in the receiving grooves. Thus, after the fixing posts GD are inserted into the receiving grooves, the fixing posts GD can be fixedly connected to the volute bottom plate 1222 by a connecting member such as a screw, and the overall height of the fan assembly 10 can also be reduced, and the device size can be reduced.
