Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a ducted air conditioner. Background Technology

[0002] Ducted air conditioners in related technologies typically include a heat exchanger, ductwork components, a motor, and multiple indoor fans. The motor drives the multiple indoor fans to operate, so that air enters the casing from the air inlet and flows into the room from the air outlet after exchanging heat with the heat exchanger.

[0003] Furthermore, in related technologies, structures for fixing the motor are usually constructed on components such as air ducts or housings to secure the motor inside the housing.

[0004] However, this design not only makes the component structure of the ducted air conditioner complex, but also makes it inconvenient to assemble and maintain the motor. Furthermore, the motor and indoor fan occupy a large axial space inside the ducted air conditioner, which is not conducive to reducing the axial dimensions of the ducted air conditioner. Utility Model Content

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a duct air conditioner that uses a mounting bracket to connect the motor and the electrical control box. The mounting bracket can be installed and removed synchronously with the motor, which simplifies the motor installation process, facilitates motor assembly and disassembly, and reduces the axial space occupied by the motor and centrifugal fan.

[0006] To achieve the above objectives, an air duct fan is proposed according to an embodiment of the present invention, comprising: a housing, wherein the housing has an air inlet and an air outlet; a heat exchanger, wherein the heat exchanger is disposed within the housing and adjacent to the air outlet; a plurality of centrifugal fans, wherein the plurality of centrifugal fans are disposed within the housing and adjacent to the air inlet, the centrifugal fans driving air to enter the housing from the air inlet, and the air flowing into the room from the air outlet after exchanging heat with the heat exchanger; an electrical control box, wherein the electrical control box is fixed within the housing and located on the same side of the plurality of centrifugal fans, and the electrical control box has a first connecting portion; and a motor, wherein the motor is disposed within the housing and located on the same side of the plurality of centrifugal fans, the motor comprising: an inner stator, wherein... The inner stator is fixed relative to the housing; the outer rotor is rotatably sleeved on the outer periphery of the inner stator, and the outer rotor is provided with a rotor shaft, which is respectively connected to a plurality of centrifugal fans to drive the plurality of centrifugal fans to rotate; the duct air conditioner further includes: a mounting bracket, which is located on the same side of the plurality of centrifugal fans, and the mounting bracket is fixedly connected to the electrical control box, and the mounting bracket is used to fix the inner stator; wherein, the mounting bracket includes: a main body, to which the inner stator is fixedly connected; a second connecting part, which is disposed adjacent to the lower side of the main body, and the mounting bracket and the electrical control box are connected to the first connecting part through the second connecting part.

[0007] The above technical solution has the following advantages or beneficial effects: The motor is connected and fixed to the electrical control box via a mounting bracket, allowing the mounting bracket to be installed and removed simultaneously with the motor. The mounting bracket does not obstruct the installation and removal of the motor relative to the housing, simplifying the installation and removal process, increasing the openness of the motor, facilitating installation, maintenance, and replacement, and improving efficiency. Furthermore, the motor bracket structure can be simpler, occupying less space, which helps save axial space within the duct unit and facilitates layout.

In other words, when assembling the duct unit, the first connecting surface extends downwards away from the electrical control box along the length of the casing. This allows disassembly tools (such as screwdrivers) to be inserted into the casing from top to bottom at an angle, providing more operating space for the disassembly tools. During use, the disassembly tools are less likely to interfere with the position of other components inside the duct unit. This makes it easier for operators to tighten the first fastener with the disassembly tools to connect the second connecting part to the first connecting surface, thereby further simplifying the assembly steps of the mounting bracket and the electrical control box, making the connection more convenient and faster, and improving the disassembly and assembly efficiency.

[0010] According to some embodiments of the present invention, the second connecting part includes: a first bending plate, one end of which is connected to the main body and the first bending plate is bent toward the electrical control box; and a second bending plate, which is connected to the other end of the first bending plate and is generally parallel to the electrical control side plate so that the second bending plate fits against the electrical control side plate.

[0019] The above technical solution has the following advantages or beneficial effects: the connecting ribs protrude from the lower side of the top plate, and the connecting holes on the connecting ribs ensure the depth of the connecting holes, thereby improving the reliability of the connection between the mounting bracket and the top plate. Furthermore, when the duct unit is installed upside down, the second connecting surface extends upwards towards the electrical control box along the length of the casing. This allows disassembly tools (such as screwdrivers) to be inserted into the casing from top to bottom at an angle, providing more operating space for the tools. During use, the tools are less likely to interfere with the top plate, making it easier for operators to tighten the second fastener to connect the fourth connecting part to the second connecting surface.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0065] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0066] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.

[0067] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0068] The following description, with reference to the accompanying drawings, describes a ductwork unit 1 according to an embodiment of the present invention.

[0069] like Figures 1-12 As shown in the attached figure, the up and down direction refers to the up and down direction of the duct unit 1 after assembly and use, the left and right direction refers to the left and right direction of the duct unit 1, that is, the length direction of the duct unit 1, and the front and back direction refers to the front and back direction of the duct unit 1, with the air inlet side being the rear and the air outlet side being the front.

[0070] According to an embodiment of the present utility model, the duct air conditioner 1 may include a housing 100, which is provided with an air inlet 110 and an air outlet 120. Air can enter the duct air conditioner 1 through the air inlet 110 and flow into the room through the air outlet 120.

[0071] The ducted air conditioner 1 may include a heat exchanger 200, which is located inside the casing 100 and adjacent to the air outlet 120. In this way, the air flowing into the ducted air conditioner 1 can exchange heat with the refrigerant in the heat exchanger 200, causing the air temperature to rise or fall. Subsequently, the air can flow into the room from the air outlet 120 to achieve heating or cooling of the room.

[0072] The ducted air conditioner 1 may include multiple centrifugal fans 300, which are located inside the housing 100 and adjacent to the air inlet 110. The centrifugal fans 300 drive air to enter the housing 100 from the air inlet 110, and after exchanging heat with the heat exchanger 200, the air flows into the room from the air outlet 120. The centrifugal fans 300 can accelerate the airflow and guide the airflow to increase the airflow for heat exchange with the heat exchanger 200, resulting in higher heat exchange efficiency.

[0073] The duct air conditioner 1 may include a motor 400, which is located inside the housing 100 and on the same side of multiple centrifugal fans 300. The motor 400 can drive the multiple centrifugal fans 300 to rotate, so that the centrifugal fans 300 can operate to drive airflow.

[0074] The motor 400 may include an inner stator 410, which is fixed relative to the housing 100. The motor 400 may also include an outer rotor 420, which is rotatably fitted around the outer periphery of the inner stator 410. The outer rotor 420 has a rotor shaft 421, which is connected to multiple centrifugal fans 300 to drive them to rotate. Thus, when the motor 400 is operating, the outer rotor 420 can rotate relative to the inner stator 410, and the rotor shaft 421 can rotate with the outer rotor 420. Furthermore, the multiple centrifugal fans 300 can be spaced apart along the axial direction of the rotor shaft 421 and are each connected to the rotor shaft 421, allowing the rotor shaft 421 to simultaneously drive multiple centrifugal fans 300 to rotate together. Additionally, it should be noted that the axial space occupied by the outer rotor motor can be relatively small, which helps to reduce the axial space occupied by the motor 400 within the housing 100, making the structure of the duct fan 1 more compact, its size smaller, and easier to install.

[0075] The ducted air conditioner 1 may also include an electrical control box 500, which is fixed inside the housing 100 and located on the same side of the plurality of centrifugal fans 300. The electrical control box 500 may be provided with a first connecting part 510. The motor 400 may be located on the same side as the electrical control box 500.

[0076] The duct unit 1 may also include a mounting bracket 600, which is located on the same side of multiple centrifugal fans 300 and is fixedly connected to the electrical control box 500. The mounting bracket 600 is used to fix the inner stator 410, so that the motor 400 can be fixed inside the housing 100 through the mounting bracket 600.

[0077] Specifically, the mounting bracket 600 may include a main body 610, with an inner stator 410 fixedly connected to the main body 610. For example, the inner stator 410 may pass through the main body 610 and be fixed relative to the main body 610. By connecting and fixing the inner stator 410 to the main body 610, the relative fixation of the motor 400 and the mounting bracket 600 can be achieved. This allows the mounting bracket 600 and the motor 400 to be disassembled and assembled simultaneously. The mounting bracket 600 will not obstruct the disassembly and assembly of the motor 400 relative to the housing, which helps to simplify the disassembly and assembly steps of the motor 400, making the disassembly and assembly of the motor 400 more open, facilitating the installation, maintenance and replacement of the motor 400, and improving the disassembly and assembly efficiency.

[0078] In addition, the mounting bracket 600 may include a second connecting part 620, which is disposed near the lower side of the main body 610. The mounting bracket 600 and the electrical control box 500 are connected to the first connecting part 510 through the second connecting part 620. In this way, the mounting bracket 600 can be connected to the electrical control box 500, that is, the motor 400 can be relatively fixed to the electrical control box 500 through the mounting bracket 600, thereby realizing the relative fixation of the motor 400 and the housing 100. Moreover, the connection and fixation of the motor 400 relative to the housing 100 is relatively simple, which facilitates the assembly and disassembly of the motor 400 relative to the housing 100.

[0079] Moreover, this design not only simplifies the structure of the electrical control box 500 or other components of the duct unit 1, but also allows for a simpler structure of the mounting bracket 600. This simplifies the installation and fixing of the motor 400 without excessively occupying the internal space of the housing 100, resulting in a more reasonable structural design.

[0080] Thus, according to the embodiment of the present utility model, the duct air conditioner 1 uses the mounting bracket 600 to connect the motor 400 and the electrical control box 500. The mounting bracket 600 can be disassembled and assembled synchronously with the motor 400, which helps to simplify the installation steps of the motor 400, facilitates the disassembly and assembly of the motor 400, and reduces the axial space occupied by the motor 400 and the centrifugal fan 300.

[0081] In some specific embodiments of this utility model, such as Figure 7 As shown, the first connecting part 510 can be constructed as a plurality of connecting bosses 511.

[0082] The electrical control box 500 has an electrical control side plate 520 on the side facing the mounting bracket 600. A connecting boss 511 is constructed on the electrical control side plate 520 and protrudes from the side of the electrical control side plate 520 facing the mounting bracket 600. The connecting boss 511 has a first connecting surface 512. The second connecting part 620 is connected to the first connecting surface 512 by a first fastener.

[0083] Specifically, multiple connecting bosses 511 can be distributed at intervals along the front-to-back direction. By having the connecting bosses 511 protrude from the side of the electrical control side plate 520 facing the mounting bracket 600, it is convenient to connect the connecting bosses 511 to the second connecting part 620. That is, it is convenient to connect and fix the electrical control box 500 to the mounting bracket 600. Furthermore, the simultaneous connection of multiple connecting bosses 511 to the second connecting part 620 can improve the connection stability between the electrical control box 500 and the mounting bracket 600. The mounting bracket 600 is less likely to rotate relative to the electrical control box 500, making the connection more reliable.

[0084] Specifically, along the length of the housing 100 away from the electrical control box 500, the first connecting surface 512 extends in a direction away from the lower side of the electrical control box 500. In other words, along the length of the housing 100 away from the electrical control box 500, the first connecting surface 512 extends upward at an angle.

[0085] It should be noted that when assembling the duct unit 1, it is usually assembled upside down, that is, the top and bottom of the duct unit 1 are reversed. In other words, when assembling the duct unit 1, the first connecting surface 512 extends downward along the length of the housing 100 away from the electrical control box 500. This allows disassembly tools (such as screwdrivers) to be inserted into the housing 100 from top to bottom at an angle, providing more operating space for the disassembly tools. During use, the disassembly tools are less likely to interfere with the position of other components inside the duct unit 1. This makes it easier for operators to tighten the first fastener with the disassembly tools to connect the second connecting part 620 to the first connecting surface 512. This further simplifies the assembly steps of the mounting bracket 600 and the electrical control box 500, making the connection more convenient and faster, and improving the disassembly and assembly efficiency.

[0086] In some specific embodiments of this utility model, such as Figure 5 , Figure 9 and Figure 10 As shown, the second connecting part 620 may include a first bending plate 621. One end of the first bending plate 621 is connected to the main body part 610, and the first bending plate 621 is bent towards the electrical control box 500. In this way, the first bending plate 621 can be closer to the electrical control box 500, and the main body part 610 is less likely to interfere with the position of the electrical control box 500, so as to facilitate the connection between the second connecting part 620 and the electrical control box 500.

[0087] The included angle between the first bending plate 621 and the main body 610 can be an acute angle, which can further improve the connection strength between the first bending plate 621 and the main body 610, and make the first bending plate 621 more resilient to stress. This can prevent the first bending plate 621 from deforming relative to the main body 610, so that the connection between the mounting bracket 600 and the electrical control box 500 is more stable and reliable.

[0088] Additionally, the second connecting portion 620 may include a second bent plate 622, which is connected to the other end of the first bent plate 621. The second bent plate 622 is bent relative to the first bent plate 621 in a direction away from the connecting boss 511. Specifically, the second bent plate 622 can be parallel to the electrical control side plate 520 so that the second bent plate 622 fits against the electrical control side plate 520. With this configuration, the contact area between the second bent plate 622 and the electrical control side plate 520 can be larger, thereby improving the connection stability between the mounting bracket 600 and the electrical control box 500.

[0089] The included angle between the second bent plate 622 and the first bent plate 621 can be an acute angle. This further enhances the connection strength between the two plates, making the second bent plate 622 more resilient and preventing deformation relative to it. This results in a more stable and reliable connection between the mounting bracket 600 and the electrical control box 500. Furthermore, this design facilitates a better fit between the second bent plate 622 and the electrical control box 500, enabling the second connecting part 620 to connect with the first connecting surface 512.

[0090] In some specific embodiments of this utility model, such as Figure 9 and Figure 10 As shown, the connection between the first bending plate 621 and the second bending plate 622 is recessed in the direction away from the connecting boss 511 to form a plurality of connecting grooves 623, and the plurality of connecting bosses 511 are correspondingly provided in the connecting grooves 623. In this way, the connecting bosses 511 can extend into the connecting grooves 623, which not only allows for pre-positioning of the connection between the mounting bracket 600 and the electrical control box 500 by the cooperation between the connecting bosses 511 and the connecting grooves 623, but also allows for limiting the mounting bracket 600 and the electrical control box 500 in the front-back direction by the sidewalls of the connecting grooves 623 abutting against the connecting bosses 511.

[0091] It should be noted that the bottom wall of the connecting groove 623 can be aligned with the extension direction of the first connecting surface 512. This facilitates the connection between the connecting groove 623 and the connecting boss 511. The first connecting surface 512 can fit against the bottom wall of the connecting groove 623, which helps to improve the connection stability between the second connecting part 620 and the first connecting part 510.

[0092] Furthermore, the first connecting surface 512 is provided with a first connecting hole 513, and the side wall of the connecting groove 623 is provided with a second connecting hole 624. The first connecting hole 513 and the second connecting hole 624 are connected by a first fastener so that the electrical control box 500 is connected to the mounting bracket 600. For example, the first fastener can be a screw, which simplifies the connection structure between the mounting bracket 600 and the electrical control box 500, facilitates disassembly and assembly, and the screw fixing can improve the connection stability between the mounting bracket 600 and the electrical control box 500. Thus, the motor 400 can be more stably fixed to the electrical control box 500 using the mounting bracket 600.

[0093] In some specific embodiments of this utility model, Figures 1-5As shown, the housing 100 may include a top plate 130, which is located on the upper side of the housing 100. That is, when the ducted air conditioner 1 is assembled and in use, the top plate 130 is located on the upper side of the housing 100. In addition, it should be noted that when the ducted air conditioner 1 is assembled, it needs to be inverted in the vertical direction, that is, the top plate 130 can be inverted and located at the bottom, so that components such as the electrical control box 500 and the centrifugal fan 300 can be installed onto the top plate 130 first.

[0094] The housing 100 may include two side plates 140, which are respectively located at both ends of the top plate 130 along its length. The electrical control box 500 is located adjacent to one end of the side plate 140 of the top plate 130, that is, the electrical control box 500 is located adjacent to one end of the housing 100 along its length.

[0095] The top plate 130 is provided with a third connecting part 131, and the mounting bracket 600 is provided with a fourth connecting part 630. The mounting bracket 600 and the top plate 130 are connected to the third connecting part 131 through the fourth connecting part 630. For example, the fourth connecting part 630 can be provided at the upper end of the mounting bracket 600, and the third connecting part 131 can be provided on the lower side of the top plate 130, which facilitates the assembly and disassembly of the fourth connecting part 630 and the third connecting part 131.

[0096] By connecting the mounting bracket 600 and the top plate 130, the two ends of the mounting bracket 600 can be fixed to the electrical control box 500 and the top plate 130 respectively, which helps to improve the fixing reliability of the mounting bracket 600 and make the connection more stable, so as to reliably fix the motor 400 using the mounting bracket 600.

[0097] In some specific embodiments of this utility model, such as Figure 7 As shown, the third connecting part 131 is constructed as a connecting rib 132, which protrudes from the lower side of the top plate 130 and has a second connecting surface 133. The fourth connecting part 630 is connected to the second connecting surface 133 by a second fastener.

[0098] The cross-sectional shape of the connecting rib 132 can be constructed as a triangle.

[0099] By making the connecting rib 132 protrude from the lower side of the top plate 130, it facilitates the connection between the fourth connecting part 630 and the connecting rib 132, that is, it facilitates the connection between the fourth connecting part 630 and the third connecting part 131. Moreover, since the connecting rib 132 protrudes from the lower side of the top plate 130, the depth of the connecting holes on the connecting rib 132 can be guaranteed, thereby improving the reliability of the connection between the mounting bracket 600 and the top plate 130.

[0100] Furthermore, along the length of the housing 100, near the electrical control box 500, the second connecting surface 133 extends in a direction away from the top plate 130. In other words, along the length of the housing 100, near the electrical control box 500, the second connecting surface 133 extends downward at an angle.

[0101] In this way, when the duct unit 1 is installed upside down, the second connecting surface 133 extends upward along the length of the housing 100 close to the electrical control box 500. This allows disassembly tools (such as screwdrivers) to be inserted into the housing 100 from top to bottom at an angle, providing more operating space for the disassembly tools. During use, the disassembly tools are less likely to interfere with the position of the top plate, making it easier for operators to tighten the second fastener to connect the fourth connecting part 630 to the second connecting surface 133. This further simplifies the assembly steps of the mounting bracket 600 and the top plate 130, making the connection more convenient and faster, and improving disassembly and assembly efficiency.

[0102] In some specific embodiments of this utility model, such as Figure 9 and Figure 10 As shown, the fourth connecting part 630 may include a third bending plate 631.

[0103] One end of the third bending plate 631 is connected to the main body 610, and the third bending plate 631 is bent away from the electrical control box 500. In this way, the third bending plate 631 will not interfere with the position of the electrical control box 500, so that the fourth connecting part 630 can be connected to the third connecting part 131 on the top plate 130.

[0104] The included angle between the third bending plate 631 and the main body 610 can be an acute angle, which can further improve the connection strength between the third bending plate 631 and the main body 610, and make the third bending plate 631 more resilient to stress. This can prevent the third bending plate 631 from deforming relative to the main body 610, so that the connection between the mounting bracket 600 and the top plate 130 is more stable and reliable.

[0105] Additionally, the fourth connecting portion 630 may include a fourth bending plate 632, which is connected to the other end of the third bending plate 631. The fourth bending plate 632 is bent relative to the third bending plate 631 in a direction close to the connecting rib 132. Specifically, the fourth bending plate 632 may be parallel to the second connecting surface 133 so that the fourth bending plate 632 fits against the second connecting surface 133.

[0106] The fourth bending plate 632 is connected to the second connecting surface 133 by a plurality of second fasteners.

[0107] By setting the fourth bending plate 632 parallel to the second connecting surface 133, the fourth bending plate 632 can fit better against the second connecting surface 133, making the connection between the fourth bending plate 632 and the second connecting surface 133 more reliable.

[0108] For example, multiple second connecting grooves 633 can be constructed on the fourth bending plate 632. The second connecting grooves 633 are recessed in a direction away from the second connecting surface 133, and the multiple second connecting grooves 633 are distributed at intervals along the length direction of the fourth bending plate 632. At the same time, multiple second connecting bosses 134 can be provided on the second connecting surface 133. The second connecting bosses 134 protrude from the side of the second connecting surface 133 facing the fourth bending plate 632, and the multiple second connecting bosses 134 extend into the multiple second connecting grooves 633 one by one, which is beneficial to improving the connection strength between the fourth connecting part 630 and the third connecting part 131.

[0109] Furthermore, such as Figure 7 and Figure 9 As shown, a third connecting hole 135 is formed on the second connecting surface 133, and a fourth connecting hole 634 is formed on the fourth bent plate 632. The third connecting hole 135 and the fourth connecting hole 634 are connected by a second fastener so that the mounting bracket 600 is connected to the top plate 130. For example, the second fastener can be a screw, which simplifies the connection structure between the mounting bracket 600 and the top plate 130, facilitates disassembly and assembly, and the screw fixing can improve the connection stability between the mounting bracket 600 and the top plate 130, thereby allowing the motor 400 to be more stably fixed relative to the top plate 130 using the mounting bracket 600.

[0110] In some other specific embodiments of this utility model, the mounting bracket 600 is provided with a fifth connecting part (not shown in the figure), and the fifth connecting part and the second connecting part 620 are respectively provided at both ends of the mounting bracket 600. In addition, the electrical control box 500 is provided with a sixth connecting part (not shown in the figure). The sixth connecting part and the first connecting part 510 are spaced apart in the vertical direction, and the mounting bracket 600 is connected to the sixth connecting part through the fifth connecting part.

[0111] In other words, both the upper and lower ends of the mounting bracket 600 can be connected and fixed to the electrical control box 500, that is, the motor 400 can be fixed to the electrical control box 500 through the mounting bracket 600.

[0112] For example, the fifth connecting portion may include a fifth bent plate and a sixth bent plate. One end of the fifth bent plate is connected to the main body 610, and the fifth bent plate is bent perpendicularly to the main body 610 in a direction closer to the electrical control box 500. The sixth bent plate is connected to the other end of the fifth bent plate, and the sixth bent plate is bent perpendicularly to the fifth bent plate in a direction away from the second connecting portion 620, so that the sixth bent plate fits against the sixth connecting portion.

[0113] Furthermore, the sixth bending plate may be provided with a connecting hole, and the sixth connecting part is also provided with a connecting hole, and the connecting hole extends in a direction perpendicular to the electrical control box 500, which makes it easy to tighten the fasteners to connect and fix the fifth connecting part and the sixth connecting part.

[0114] In some specific embodiments of this utility model, such as Figure 7 , Figure 11 and Figure 12 As shown, the duct unit 1 may also include auxiliary fasteners 700.

[0115] The auxiliary fixing member 700 is connected to the side of the main body 610 facing the electrical control box 500, and the auxiliary fixing member 700 and the main body 610 clamp the inner stator 410 to fix the inner stator 410. With this configuration, the main body 610 and the auxiliary fixing member 700 can fix the inner stator 410 on both sides of the axial direction in the axial direction, preventing the inner stator 410 from shaking along its axial direction, thereby achieving the fixation of the inner stator 410.

[0116] Furthermore, the main body 610 is provided with a clearance hole 611, a part of the inner stator 410 passes through the clearance hole 611, and another part of the inner stator 410 is stopped on the side of the main body 610 facing the electrical control box 500.

[0117] In this way, the clearance hole 611 can make way for a part of the inner stator 410 so that a part of the inner stator 410 can pass through the main body 610. The outer rotor 420 can be sleeved on the inner stator 410 and connected to the inner stator 410 by magnetic force. When the motor 400 is running, the outer rotor 420 can rotate relative to the inner stator 410 to drive the multiple centrifugal fans 300 to run.

[0118] In this configuration, after a portion of the inner stator 410 passes through the clearance hole 611, another portion of the inner stator 410 can be stopped on the side of the main body 610 facing the electrical control box 500. Then, the auxiliary fixing member 700 is used to fix and stop the side of the inner stator 410 facing the electrical control box 500. Thus, the main body 610 and the auxiliary fixing member 700 can be used to fix the inner stator 410 in the axial direction, preventing the inner stator 410 from shaking along its axial direction, thereby achieving the fixation of the inner stator 410.

[0119] In some specific embodiments of this utility model, such as Figure 9 and Figure 10As shown, the clearance hole 611 is provided with a plurality of first limiting grooves 612 in the circumferential direction. The first limiting grooves 612 are recessed in the direction away from the auxiliary fixing member 700. The auxiliary fixing member 700 is provided with a plurality of second limiting grooves 710 in the circumferential direction. The second limiting grooves 710 are recessed in the direction away from the mounting bracket 600. The plurality of second limiting grooves 710 and the plurality of first limiting grooves 612 correspond one-to-one to define the plurality of limiting grooves.

[0120] The inner stator 410 has multiple limiting protrusions 411 spaced apart on its outer periphery, and the multiple limiting protrusions 411 are respectively located in multiple limiting grooves 711.

[0121] In this way, the limiting boss 411 can be engaged in the limiting groove 711. By abutting the limiting boss 411 through the side wall of the limiting groove 711, the inner stator 410 can be limited in the circumferential direction, preventing the inner stator 410 from rotating relative to the main body 610, ensuring that the inner stator 410 can be stably fixed to the main body 610, and making the motor 400 and the mounting bracket 600 stably connected.

[0122] In some specific embodiments of this utility model, such as Figure 10 and Figure 11 As shown, one of the auxiliary fastener 700 and the mounting bracket 600 is provided with multiple positioning protrusions 613, and the other of the auxiliary fastener 700 and the mounting bracket 600 is provided with multiple positioning grooves 712, with the multiple positioning protrusions 613 extending into the multiple positioning grooves 712 in a one-to-one correspondence.

[0123] For example, multiple positioning grooves 712 can be provided on the auxiliary fastener 700, and multiple positioning protrusions 613 can be provided on the mounting bracket 600. The multiple positioning grooves 712 can be arranged at intervals along the circumference of the auxiliary fastener 700, and the multiple positioning protrusions 613 can be arranged at intervals along the circumference of the mounting bracket 600. Through the positioning engagement of the positioning protrusions 613 and the positioning grooves 712, the auxiliary fastener 700 and the mounting bracket 600 can be pre-positioned, which helps to simplify the assembly steps of the auxiliary fastener 700 and the mounting bracket 600.

[0124] In some specific embodiments of this utility model, such as Figures 9-12 As shown, the auxiliary fixing member 700 is provided with multiple fifth connecting holes 713, and the mounting bracket 600 is provided with multiple sixth connecting holes 614. The multiple fifth connecting holes 713 and multiple sixth connecting holes 614 are connected one-to-one by a third fastener. In this way, the auxiliary fixing member 700 and the mounting bracket 600 can be fixed relative to each other, so as to stably clamp and fix the motor 400 using the auxiliary fixing member 700 and the mounting bracket 600.

[0125] In some specific embodiments of this utility model, such as Figure 5and Figure 7 As shown, the duct unit 1 may also include an elastic buffer 800. The elastic buffer 800 may be a rubber component.

[0126] The elastic buffer 800 is disposed between the auxiliary fixing member 700 and the mounting bracket 600. The elastic buffer 800 is sleeved on the outer peripheral surface of the inner stator 410, and at least a portion of the elastic buffer 800 stops the inner stator 410 on the side facing the auxiliary fixing member 700.

[0127] By adding an elastic buffer 800, the inner stator 410 can be prevented from directly contacting the auxiliary fixing part 700 or the mounting bracket 600. The elastic buffer 800 can buffer and protect the inner stator 410, preventing wear between the inner stator 410 and the mounting bracket 600 or the auxiliary fixing part 700. Furthermore, when the motor 400 is working, the elastic buffer 800 can also absorb vibration and noise to achieve the purpose of vibration reduction and noise reduction.

[0128] In some specific embodiments of this utility model, such as Figure 4 and Figure 7 As shown, the duct unit 1 may also include a bearing bracket 900.

[0129] The bearing bracket 900 is fixed inside the housing 100 and adjacent to the other side of the housing 100 along its length. A bearing 910 is housed within the bearing bracket 900, and the end of the rotor shaft 421 furthest from the outer rotor 420 is rotatably fitted into the bearing 910. The bearing bracket 900 can be fixed to the side plate 140, or it can be fixed to other locations within the housing 100, such as the top plate 130 or the bottom plate.

[0130] In this way, the bearing bracket 900 and the bearing 910 can support the end of the rotor shaft 421 away from the outer rotor 420, and the rotor shaft 421 can rotate relative to the bearing bracket 900 so as to drive multiple centrifugal fans 300 to rotate together.

[0131] The following description, with reference to the accompanying drawings, describes a ductwork unit 1 according to an embodiment of the present invention.

[0132] According to an embodiment of the present utility model, the duct air conditioner 1 may include a housing 100, which is provided with an air inlet 110 and an air outlet 120. Air can enter the duct air conditioner 1 through the air inlet 110 and flow into the room through the air outlet 120.

[0133] The ducted air conditioner 1 may include a heat exchanger 200, which is located inside the casing 100 and adjacent to the air outlet 120. In this way, the air flowing into the ducted air conditioner 1 can exchange heat with the refrigerant in the heat exchanger 200, causing the air temperature to rise or fall. Subsequently, the air can flow into the room from the air outlet 120 to achieve heating or cooling of the room.

[0134] The ducted air conditioner 1 may include multiple centrifugal fans 300, which are located inside the housing 100 and adjacent to the air inlet 110. The centrifugal fans 300 drive air to enter the housing 100 from the air inlet 110, and after exchanging heat with the heat exchanger 200, the air flows into the room from the air outlet 120. The centrifugal fans 300 can accelerate the airflow and guide the airflow to increase the airflow for heat exchange with the heat exchanger 200, resulting in higher heat exchange efficiency.

[0135] The duct air conditioner 1 may include a motor 400, which is located inside the housing 100 and on the same side of multiple centrifugal fans 300. The motor 400 can drive the multiple centrifugal fans 300 to rotate, so that the centrifugal fans 300 can operate to drive airflow.

[0136] The motor 400 may include an inner stator 410, which is fixed relative to the housing 100. The motor 400 may also include an outer rotor 420, which is rotatably fitted around the outer periphery of the inner stator 410. The outer rotor 420 has a rotor shaft 421, which is connected to multiple centrifugal fans 300 to drive them to rotate. Thus, when the motor 400 is operating, the outer rotor 420 can rotate relative to the inner stator 410, and the rotor shaft 421 can rotate with the outer rotor 420. Furthermore, the multiple centrifugal fans 300 can be spaced apart along the axial direction of the rotor shaft 421 and are each connected to the rotor shaft 421, allowing the rotor shaft 421 to simultaneously drive multiple centrifugal fans 300 to rotate together. Additionally, it should be noted that the axial space occupied by the outer rotor motor can be relatively small, which helps to reduce the axial space occupied by the motor 400 within the housing 100, making the structure of the duct fan 1 more compact, its size smaller, and easier to install.

[0137] The housing 100 is provided with a plurality of side plates 140, which are respectively located at opposite ends of the housing 100 in the length direction, and one of the side plates 140 is provided with a side plate connecting part.

[0138] The duct unit 1 may also include a mounting bracket 600, which is located on the same side of multiple centrifugal fans 300 and is fixedly connected to the electrical control box 500. The mounting bracket 600 is used to fix the inner stator 410, so that the motor 400 can be fixed inside the housing 100 through the mounting bracket 600.

[0139] Specifically, the mounting bracket 600 may include a main body 610, with an inner stator 410 fixedly connected to the main body 610. For example, the inner stator 410 may pass through the main body 610 and be fixed relative to the main body 610. By connecting and fixing the inner stator 410 to the main body 610, the relative fixation of the motor 400 and the mounting bracket 600 can be achieved. This allows the mounting bracket 600 and the motor 400 to be disassembled and assembled simultaneously. The mounting bracket 600 will not obstruct the disassembly and assembly of the motor 400 relative to the housing, which helps to simplify the disassembly and assembly steps of the motor 400, making the disassembly and assembly of the motor 400 more open, facilitating the installation, maintenance and replacement of the motor 400, and improving the disassembly and assembly efficiency.

[0140] In addition, the mounting bracket 600 may include a second connecting part 620, which is adjacent to the lower side of the main body 610. The mounting bracket 600 and the side plate 140 are connected to the side plate connecting part through the second connecting part 620. In this way, the mounting bracket 600 can be connected to the side plate 140, that is, the motor 400 can be relatively fixed to the side plate 140 through the mounting bracket 600, thereby realizing the relative fixation of the motor 400 and the housing 100. Moreover, the connection and fixation of the motor 400 relative to the housing 100 is relatively simple, which facilitates the assembly and disassembly of the motor 400 relative to the housing 100.

[0141] Moreover, this design eliminates the need to fabricate structures for fixing the motor 400 on the side panel 140 or other components of the duct unit 1. This not only simplifies the structure of the side panel 140 or other components of the duct unit 1, but also allows for a simpler structure for the mounting bracket 600. This simplifies the installation and fixing of the motor 400 without excessively occupying the internal space of the housing 100, resulting in a more rational structural design.

[0142] Thus, according to the embodiment of the present utility model, the duct air conditioner 1 uses the mounting bracket 600 to connect the motor 400 to the side plate 140. The mounting bracket 600 can be disassembled and assembled simultaneously with the motor 400, which helps to simplify the installation steps of the motor 400, facilitates the disassembly and assembly of the motor 400, and reduces the axial space occupied by the motor 400 and the centrifugal fan 300.

[0143] In some specific embodiments of this utility model, the second connecting part 620 may include a first bending plate 621. One end of the first bending plate 621 is connected to the main body part 610, and the first bending plate 621 is bent towards the side plate 140. In this way, the first bending plate 621 can be closer to the side plate 140, and the main body part 610 is less likely to interfere with the side plate 140, so as to facilitate the connection between the second connecting part 620 and the side plate 140.

[0144] The included angle between the first bending plate 621 and the main body 610 can be an acute angle, which can further improve the connection strength between the first bending plate 621 and the main body 610, and make the first bending plate 621 more resilient to stress, thereby preventing the first bending plate 621 from deforming relative to the main body 610, so that the connection between the mounting bracket 600 and the side plate 140 is more stable and reliable.

[0145] Additionally, the second connecting portion 620 may include a second bent plate 622, which is connected to the other end of the first bent plate 621. The second bent plate 622 can be parallel to the side plate 140 as a whole, so that the second bent plate 622 fits against the side plate 140. With this configuration, the contact area between the second bent plate 622 and the side plate 140 can be larger, thereby improving the connection stability between the mounting bracket 600 and the side plate 140.

[0146] In some specific embodiments of this utility model, the housing 100 may include a top plate 130, which is located on the upper side of the housing 100. That is, when the duct air conditioner 1 is assembled and in use, the top plate 130 is located on the upper side of the housing 100. In addition, it should be noted that when the duct air conditioner 1 is assembled, it needs to be inverted in the vertical direction, that is, the top plate 130 can be inverted and located at the bottom, so as to facilitate the installation of components such as the electrical control box 500 and the centrifugal fan 300 onto the top plate 130 first.

[0147] The top plate 130 is provided with a third connecting part 131, and the mounting bracket 600 is provided with a fourth connecting part 630. The mounting bracket 600 and the top plate 130 are connected to the third connecting part 131 through the fourth connecting part 630. For example, the fourth connecting part 630 can be provided at the upper end of the mounting bracket 600, and the third connecting part 131 can be provided on the lower side of the top plate 130, which facilitates the assembly and disassembly of the fourth connecting part 630 and the third connecting part 131.

[0148] By connecting the mounting bracket 600 and the top plate 130, the two ends of the mounting bracket 600 can be fixed to the side plate 140 and the top plate 130 respectively, which helps to improve the fixing reliability of the mounting bracket 600 and make the connection more stable, so as to reliably fix the motor 400 using the mounting bracket 600.

[0149] Furthermore, the fourth connecting portion 630 may include a third bending plate 631.

[0150] One end of the third bending plate 631 is connected to the main body 610, and the third bending plate 631 is bent away from the side plate 140, so that the third bending plate 631 will not interfere with the position of the side plate 140, so that the fourth connecting part 630 can be connected to the third connecting part 131 on the top plate 130.

[0151] The included angle between the third bending plate 631 and the main body 610 can be an acute angle, which can further improve the connection strength between the third bending plate 631 and the main body 610, and make the third bending plate 631 more resilient to stress. This can prevent the third bending plate 631 from deforming relative to the main body 610, so that the connection between the mounting bracket 600 and the top plate 130 is more stable and reliable.

[0152] Additionally, the fourth connecting portion 630 may include a fourth bending plate 632, which is connected to the other end of the third bending plate 631. The fourth bending plate 632 is bent relative to the third bending plate 631 in a direction closer to the third connecting portion 131. Specifically, the fourth bending plate 623 may be parallel to the third connecting portion 131 so that the fourth bending plate 632 fits against the third connecting portion 131, making the connection between the fourth connecting portion 630 and the third connecting portion 131 more reliable.

[0153] Other components and operations of the ductwork unit 1 according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.

[0154] The ducted air conditioner 1 of this invention performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0155] The compressor compresses refrigerant gas under high temperature and pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0156] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the ducted air conditioner 1 regulates the temperature and humidity of the indoor space.
