[0031] The present application embodiment provides a duct machine, see Figure 1 and Figure 2 The air duct machine includes a chassis 20, a wind wheel 30, a driving motor 40 and an air duct structure 10.

[0032] See also Figure 1 , Figure 2 , Figures 3 to 8 The air duct structure 10 of the embodiment of the present application includes a partition 11, a volute 12 and a motor mounting assembly 13.

[0033] The partition 11 has a communication port 11a, the volute 12 has an airflow passage 12a, the volute 12 is arranged on the partition 11, and one end of the airflow passage 12a along the airflow direction is located at the communication port 11a. The motor mounting assembly 13 includes a motor mounting frame 131, which is arranged on one side of the volute 12 and is integrally formed with the partition 11.

[0034] Please continue reading Figure 1 , Figure 2 and Figure 4The partition 11 is arranged on the chassis 20 , the wind wheel 30 is installed in the volute 12 , and the driving motor 40 is installed on the motor mounting frame 131 and is drivingly connected to the wind wheel 30 .

[0035] Specifically, the partition 11 is used to separate two areas on the chassis 20, the volute 12, the motor mounting assembly 13, the wind wheel 30 and the drive motor 40 are arranged in the same area, and the heat exchanger and other components are arranged in another area, which is equivalent to the volute 12, the motor mounting bracket 131, the wind wheel 30 and the drive motor 40 being arranged on the same side of the partition 11, and the heat exchanger being arranged on the other side opposite to the partition 11.

[0036] One end of the airflow channel 12a along the airflow direction is located at the communication port 11a, which means that the two areas separated on the chassis 20 can be connected through the airflow channel 12a and the communication port 11a.

[0037] See also Figure 6 and Figure 8 , one end of the volute 12 close to the communication port 11a is located on the side of the partition 11 provided with the motor mounting bracket 131. In other words, the volute 12 does not extend from the communication port 11a to the side of the partition 11 away from the motor mounting bracket 131.

[0038] In other embodiments, the volute 12 may be inserted into the connecting port 11a, and one end of the volute 12 close to the connecting port 11a extends from the connecting port 11a to the side of the partition 11 away from the motor mounting frame 131, which means that the connecting port 11a is only used to install the volute 12, and the air flow channel 12a is not connected to the connecting port 11a.

[0039] However, compared with the case 12 being inserted into the communication port 11a, the end of the case 12 close to the communication port 11a is located on the side of the partition 11 where the motor mounting bracket 131 is provided, which can increase the air volume by at least 40m 3 / h.

[0040] Depending on the type of the air duct machine, the air flow may first enter the air flow channel 12a of the volute 12 and then flow to the heat exchanger from the connecting port 11a, or may first pass through the heat exchanger and then enter the air flow channel 12a of the volute 12 from the connecting port 11a. In other words, the air duct machine of the embodiment of the present application may be a blowing air duct machine or a suction air duct machine.

[0041] The driving motor 40 drives the wind wheel 30 to rotate, so that the airflow flows through the airflow channel 12a.

[0042] Please continue reading Figure 1 , Figure 2 , Figure 4 and Figure 6The motor mounting frame 131 is used to support the driving motor 40 , and the motor mounting frame 131 and the partition plate 11 are integrally formed, which means that the motor mounting frame 131 and the partition plate 11 are an inseparable integral structure.

[0043] Exemplarily, the motor mounting bracket 131 and the partition plate 11 may be integrally formed by injection molding.

[0044] In the related art, the motor mounting frame is generally fixed to the partition by screws. Therefore, the motor mounting frame is prone to installation deviation during the installation process, thereby reducing the coaxiality between the drive motor and the wind wheel.

[0045] The motor mounting frame 131 of the embodiment of the present application is integrally formed with the partition 11, which can better ensure that the position of the motor mounting frame 131 on the partition 11 will not deviate, thereby better ensuring that the coaxiality of the drive motor 40 and the wind wheel 30 can meet the requirements.

[0046] In addition, the motor mounting frame 131 and the partition plate 11 are integrally formed, which can also reduce the number of parts of the air duct structure 10 and improve the production and assembly efficiency of the air duct machine.

[0047] In one embodiment, please refer to Figure 1 , Figure 2 , Figures 4 to 6 The air duct structure 10 includes a motor cover 132, which is detachably connected to the motor mounting frame 131 to jointly define a motor accommodating chamber 13a. That is, the motor cover 132 can be separated from the motor mounting frame 131, and the motor cover 132 is detachably connected to the motor mounting frame 131 to fix the drive motor 40 in the motor accommodating chamber 13a.

[0048] There is no limitation on the manner in which the motor cover 132 and the motor mounting frame 131 are detachably connected. For example, the motor cover 132 and the motor mounting frame 131 may be fastened together by fasteners such as screws and bolts. In other embodiments, the motor cover 132 may also be snap-fitted to the motor mounting frame 131.

[0049] The motor cover 132 can limit the driving motor 40 to better prevent the position of the driving motor 40 from being offset, thereby better ensuring that the coaxiality of the driving motor 40 and the wind wheel 30 can meet the requirements.

[0050] See also Figure 5 and Figure 7 The partition 11 may be provided with a positioning slot 11b, and the motor cover 132 may be provided with a plug-in component 132a. The plug-in component 132a may play a positioning role for the motor cover 132 by being inserted into the positioning slot 11b.

[0051] In some other embodiments, the partition 11 may be provided with a plug-in connector 132 a , and the motor cover 132 may be provided with a positioning slot 11 b .

[0052] See also Figures 5 to 7 For the air duct structure 10 in which the motor cover 132 is fastened to the motor mounting frame 131, the motor mounting frame 131 may be provided with a positioning buckle 131a, and the motor cover 132 may be provided with a positioning slot 132b, and the positioning buckle 131a is snapped into the positioning slot 132b.

[0053] The positioning buckle 131a can play a role of pre-fixing the motor cover 132 by being inserted into the positioning slot 132b. Specifically, when the duct unit is installed indoors, the chassis 20 is generally facing the ceiling, that is, the motor mounting frame 131 is located at the lower side of the chassis 20. Therefore, during the maintenance process, after the drive motor 40 is placed on the motor mounting frame 131, the positioning buckle 131a on the motor mounting frame 131 can be inserted into the positioning slot 132b on the motor cover 132, and then the fastener is installed. Therefore, the installation of the motor cover 132 can be completed without the operator holding the motor cover 132, thereby improving the convenience of installing the motor cover 132.

[0054] In other embodiments, the motor mounting frame 131 may be provided with a positioning slot 132 b , and the motor cover 132 may be provided with a positioning buckle 131 a .

[0055] In some other embodiments, the motor mounting assembly 13 may not be provided with the motor cover 132 , for example, the driving motor 40 may be directly connected to the motor mounting bracket 131 .

[0056] Please continue reading Figure 1 , Figure 4 and Figure 6 The air duct structure 10 can be provided with a first wire fastener 15 on the motor mounting frame 131 to facilitate fixing the motor wire of the driving motor 40 .

[0057] See also Figure 1 , Figure 4 and Figure 6 A second wire fastener 16 may be provided on one side of the partition 11 where the motor mounting bracket 131 is provided, so as to fix the cables including the motor wires of the driving motor 40 .

[0058] Likewise, see Figure 8 A second wire fastener 16 may also be provided on the side of the partition 11 away from the motor mounting frame 131 to facilitate fixing the cables of components such as the heat exchanger.

[0059] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 The volute 12 includes a first shell 121 and a second shell 122. The first shell 121 can be integrally formed with the partition 11, that is, the first shell 121 and the partition 11 are an integral structure. The second shell 122 is detachably connected to the first shell 121, and the second shell 122 and the first shell 121 jointly define an airflow channel 12a.

[0060] The manner in which the second shell 122 and the first shell 121 are detachably connected is not limited. For example, the second shell 122 and the first shell 121 may be fastened or snap-connected.

[0061] The second shell 122 is detachably connected to the first shell 121 to facilitate the disassembly and assembly of the wind wheel 30, and the first shell 121 is integrally formed with the partition 11, which can not only reduce the installation deviation of the volute 12, but also reduce the number of parts of the air duct structure 10, thereby improving the production and assembly efficiency of the duct machine.

[0062] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 The air duct structure 10 includes a shaft support seat 14 arranged on the partition 11. The shaft support seat 14 is located on the side of the volute 12 away from the motor mounting frame 131 and is integrally formed with the partition 11. That is, the shaft support seat 14 and the partition 11 are an integral structure.

[0063] Specifically, see Figure 1 and Figure 4 The wind wheel 30 is generally installed on the rotating shaft 50 , and the rotating shaft support seat 14 is used to support the rotating shaft 50 .

[0064] For example, see Figure 4 A bearing 60 may be disposed on the rotating shaft support seat 14 , and the rotating shaft 50 is connected to the bearing 60 .

[0065] The shaft support seat 14 and the partition plate 11 are integrally formed, which can not only effectively prevent the installation position of the shaft support seat 14 from being deviated, but also reduce the number of parts of the air duct structure 10 and improve the production and assembly efficiency of the air duct machine.

[0066] In one embodiment, please refer to Figure 2 , the motor mounting bracket 131 can be detachably connected to the chassis 20.

[0067] The manner in which the motor mounting bracket 131 and the chassis 20 are detachably connected is not limited. For example, the motor mounting bracket 131 and the chassis 20 may be fastened or clamped.

[0068] The motor mounting frame 131 is detachably connected to the chassis 20, which can further fix the motor mounting frame 131. This not only improves the stability and reliability of the installation of the drive motor 40, but also better prevents the motor mounting frame 131 from deformation when the duct machine is impacted by external force.

[0069] See also Figure 3 The chassis 20 may be provided with a limiting protrusion 20a, which protrudes toward the side of the chassis 20 where the partition 11 is provided. The partition 11 abuts against the limiting protrusion 20a, which can play a self-positioning role in the installation of the partition 11, thereby also improving the production and assembly efficiency of the air duct machine.
