[0065] The air duct machine provided in the embodiments of the present application may have various implementation forms. Figure 1-Figure 13 This is a specific implementation of the duct machine of this application.

[0066] As attached Figure 1 As shown, the duct machine includes a casing 100, which is used to form the appearance of the duct machine. The left side of the casing 100 and the right side of the casing 100 are two sides of the casing 100 that are opposite to each other in the horizontal direction; the left side of the casing 100 to the right side of the casing 100 is the length direction of the casing 100; the top of the casing 100 and the bottom of the casing 100 are two sides of the casing 100 that are opposite to each other in the vertical direction, and the top of the casing 100 to the bottom of the casing 100 is the height direction of the casing 100; the front side of the casing 100 and the rear side of the casing 100 are the other two sides of the casing 100 that are opposite to each other in the horizontal direction, and the front side of the casing 100 to the rear side of the casing 100 is the thickness direction of the casing 100.

[0067] like Figure 1 and Figure 2As shown, the housing 100 includes a housing air inlet 101, and indoor air enters the housing 100 through the housing air inlet 101. The housing air inlet 101 extends along the length direction of the housing 100 to increase the opening size of the housing air inlet 101, so that the air duct unit has a larger air intake volume. The housing air inlet 101 is opened on one side of the housing 100 arranged in the horizontal direction, and the opening direction of the housing air inlet 101 is usually arranged in the horizontal direction.

[0068] like Figure 2 As shown, the housing 100 includes a housing air outlet 102, and the air in the housing 100 is output to the room through the housing air outlet 102. The housing air outlet 102 extends along the length direction of the housing 100 to increase the opening size of the housing air outlet 102, so that the air duct machine has a larger air output. The housing air outlet 102 and the housing air inlet 101 are correspondingly opened on two opposite sides of the housing 100 in the horizontal direction, and the opening direction of the housing air outlet 102 is usually set in the horizontal direction.

[0069] like Figure 1 As shown, in this embodiment, the casing air inlet 101 is opened at the front side of the casing 100 , and the casing air outlet 102 is opened at the rear side of the casing 100 .

[0070] like Figure 1-Figure 3 As shown, the air duct unit includes a heat exchanger 200, which is arranged inside the housing 100, and is arranged near the housing air inlet 101, for performing heat exchange processing on the air entering the housing 100, so that the air inside the housing 100 is heat exchanged to form air-conditioned air; it should be noted that the air-conditioned air may be cold air, hot air, or even normal temperature air. It should also be noted that the length direction of the heat exchanger 200 is roughly arranged along the length direction of the housing 100.

[0071] like Figure 2 As shown, the heat exchanger 200 includes a first section 210, which is arranged to be inclined upward along the height direction of the casing 100, with the upper end of the first section 210 arranged close to the top of the casing 100 and the lower end of the first section 210 arranged toward the casing air inlet 101.

[0072] like Figure 2 As shown, the heat exchanger 200 includes a second section 220, which is inclined downward along the height direction of the casing 100, the upper end of the second section 220 is arranged close to the top of the casing 100, and the lower end of the second section 220 is arranged toward the casing air inlet 101; the upper end of the second section 220 and the lower end of the first section 210 are abutted against each other.

[0073] like Figure 2As shown, the heat exchanger 200 includes a third section 230, which is tilted downward along the height direction of the casing 100, the upper end of the third section 230 abuts against the lower end of the second section 220, and the lower end of the third section 230 is arranged toward the casing air outlet 102.

[0074] It should be noted that the first section 210 , the second section 220 and the third section 230 are interconnected to form a semi-enclosed structure.

[0075] It should also be noted that by obliquely arranging the first section 210 , the second section 220 and the third section 230 in the casing 100 , the heat exchange area of ​​the heat exchanger 200 can be increased as much as possible within the same installation space, thereby improving the heat exchange efficiency of the heat exchanger 200 .

[0076] like Figure 7 and Figure 8 As shown, the duct unit includes a first end plate 800, which is used to fix the heat exchanger 200; the first end plate 800 is arranged inside the casing 100, the first end plate 800 is connected to one end of the heat exchanger 200 in the length direction, and the first end plate 800 is installed on the casing 100.

[0077] like Figure 7 and Figure 8 As shown, the duct unit includes a second end plate 600, which is used to fix the heat exchanger 200; the second end plate 600 is arranged inside the casing 100, and the second end plate 600 and the first end plate 800 are arranged correspondingly along the length direction of the heat exchanger 200, the second end plate 600 is connected to the other end of the length direction of the heat exchanger 200, and the second end plate 600 is installed on the casing 100.

[0078] The heat exchanger 200 is installed inside the housing 100 by correspondingly disposing the first end plate 800 and the second end plate 600 at both ends of the heat exchanger 200 in the length direction.

[0079] The first end plate 800 , the second end plate 600 and the heat exchanger 200 together define a receiving space, which is located on the leeward side of the heat exchanger 200 . The receiving space includes an opening disposed toward the air outlet 102 of the casing.

[0080] like Figure 2 and Figure 3 As shown, the duct air conditioner includes a heat exchange fan, which is located in the casing 100 and is arranged near the casing air outlet 102. Through the operation of the heat exchange fan, the external air of the casing 100 is introduced into the casing 100 through the casing air inlet 101, and after heat exchange in the heat exchanger 200, it flows to the casing 100 through the casing air outlet 102.

[0081] like Figure 3As shown, the heat exchange fan includes a fan 400, which is installed on the casing 100 and arranged on the leeward side of the heat exchanger 200; it should be noted that the fan 400 is a cross-flow fan 400, and the axial direction of the fan 400 is arranged along the length direction of the casing 100.

[0082] like Figure 2 As shown, the upper end of the first section 210 is located above the fan 400, the lower end of the second section 220 and the third section 230 are located below the fan 400, and the fan 400 is located at the opening of the accommodating space.

[0083] like Figure 3 As shown, the heat exchange fan includes a motor 500, which is installed in the housing 100 and connected to the fan 400 to drive the fan 400 to operate. The motor 500 and the fan 400 are arranged along the length direction of the housing 100.

[0084] like Figure 2 As shown, the duct unit includes an electric heating assembly 300, which is arranged in the accommodation space and is used to heat the air passing through the accommodation space. It should be noted that the length direction of the electric heating assembly 300 is roughly arranged in the same direction as the length direction of the heat exchanger 200.

[0085] It should be noted that when the air duct unit is heating, the electric heating assembly 300 is working so that the electric heating assembly 300 and the heat exchanger 200 heat the air entering the casing 100 at the same time, thereby increasing the heating performance of the air duct unit.

[0086] When the duct air conditioner is heating, the air outside the casing 100 is introduced into the casing 100 through the casing air inlet 101 under the operation of the heat exchange fan, enters the accommodating space after heat exchange in the heat exchanger 200, is heated again by the electric heating component 300, and finally flows into the casing 100 through the casing air outlet 102.

[0087] like Figure 5 and Figure 6 As shown, the first end plate 800 is provided with a through portion 810 , and the through portion 810 is communicated with the accommodation space, so that the electric heating component 300 can be arranged in the accommodation space or removed from the accommodation space through the through portion 810 .

[0088] By providing a through portion 810 on the first end plate 800 , the electric heating component 300 can be placed in the accommodation space or removed from the accommodation space through the through portion 810 . The electric heating component 300 can be installed and removed without removing the heat exchanger 200 .

[0089] In some embodiments, the through portion 810 is a through opening provided on the first end plate 800 , and the opening of the through opening is provided along the length direction of the electric heating component 300 .

[0090] like Figure 6 As shown, a reinforcing portion 820 is provided on the side of the first end plate 800 facing away from the accommodating space, and the reinforcing portion 820 is protruding from the surface of the first end plate 800 to increase the strength of the first end plate 800 and avoid reducing the strength of the first end plate 800 due to the provision of the through portion 810 on the first end plate 800.

[0091] In some embodiments, the first end plate 800 is a plastic part. On the one hand, plastic parts are lighter than sheet metal parts. On the other hand, plastic parts are poor conductors of heat, which can prevent the heat of the heat exchanger 200 from being transferred to the first end plate 800. It can also prevent the hands from accidentally touching the first end plate 800 and being burned by the first end plate 800 when disassembling the electric heating component 300.

[0092] like Figure 4 As shown, the duct machine includes a fixing member 700, which is used to fix the electric heating component 300; the fixing member 700 is arranged at one end of the electric heating component 300 in the length direction, at least part of the fixing member 700 is located outside the accommodating space, and the fixing member 700 is interconnected with the first end plate 800 so that the electric heating component 300 can be reliably arranged in the accommodating space.

[0093] like Fig.10 and Fig.11 As shown, the fixing member 700 is provided with a first accommodating portion 710 , the first accommodating portion 710 is arranged in the accommodating space, and one end of the electric heating component 300 in the length direction is arranged in the first accommodating portion 710 .

[0094] In some embodiments, the electric heating component 300 is interference-fitted with the first receiving portion 710 so that the electric heating component 300 and the fixing member 700 are connected to each other.

[0095] The first accommodating portion 710 is provided with an escape portion 740, which is arranged along a first direction and passes through the side wall of one side of the first accommodating portion 710, and the first direction intersects with the length direction of the electric heating component 300. By providing the escape portion 740 on the side wall of the first accommodating portion 710, the electric heating component 300 is prevented from damaging the first accommodating portion 710, and the fixing member 700 can also be connected to electric heating components 300 of different specifications, thereby increasing the adaptability of the fixing member 700.

[0096] In some embodiments, the fixing member 700 is provided with a through cavity, which extends along the length direction of the electric heating component 300 and is connected to the first accommodating portion 710. This design can reduce the weight of the fixing member 700 and facilitate the routing of the circuit connected to the electric heating component 300.

[0097] In other embodiments, the avoidance portion 740 extends along the length direction of the electric heating component 300 to the side wall of the through cavity.

[0098] like Figure 8 , Fig.10 and Fig.11 As shown, the fixing member 700 is provided with a blocking portion 720, and the blocking portion 720 is arranged on the outer peripheral surface of the protruding fixing member 700, and the blocking portion 720 is arranged outside the accommodating space. The blocking portion 720 is in contact with the side of the first end plate 800 facing away from the accommodating space, and the blocking portion 720 is arranged to cover the outer edge of the passing portion 810 to block the passing portion 810 and prevent the air heated by the electric heating component 300 in the accommodating space from leaking through the passing portion 810.

[0099] The blocking portion 720 may also increase the contact area between the fixing member 700 and the first end plate 800 , thereby facilitating the connection between the fixing member 700 and the first end plate 800 .

[0100] In this embodiment, the blocking portion 720 is connected to the first end plate 800 via a fastener, so that the fixing member 700 is connected to the first end plate 800 .

[0101] Specifically, the blocking portion 720 is provided with a first connection hole, and the first connection hole is provided through the blocking portion 720 along the length direction of the electric heating component 300 .

[0102] The first end plate 800 is provided with a second connection hole, and the second connection hole is arranged to penetrate the first end plate 800 along the length direction of the electric heating component 300, and the second connection hole is arranged corresponding to the first connection hole.

[0103] When the fixing member 700 is connected to the first end plate 800, the second connecting hole and the first connecting hole are aligned with each other so that the same fastener such as a bolt or a screw is simultaneously arranged in the first connecting hole and the second connecting hole to connect the fixing member 700 to the first end plate 800.

[0104] In some embodiments, the first connection hole is set to be multiple, and correspondingly, the second connection hole is also set to be multiple, and the multiple second connection holes are set one-to-one corresponding to the multiple first connection holes to increase the connection strength between the fixing member 700 and the first end plate 800.

[0105] In other embodiments, two first connecting holes are provided, and the line connecting the two first connecting holes is inclined in a vertical plane; two second connecting holes are also provided, and the two second connecting holes are provided in one-to-one correspondence with the two first connecting holes, and the line connecting the two first connecting holes is inclined in a vertical plane. This design can reduce the number of fasteners while ensuring the connection strength between the fixing member 700 and the first end plate 800.

[0106] It should be noted that aligning the first connection hole and the second connection hole with each other can not only facilitate the fastener to connect the fixing member 700 and the first end plate 800, but also locate the connection position of the fixing member 700 and the first end plate 800.

[0107] It should be noted that the blocking portion 720 cooperates with the outer edge of the through portion 810 on the side away from the accommodating space, and can also position and constrain the fixing member 700 in the length direction of the housing 100, limiting the transition of the fixing member 700 into the accommodating space.

[0108] like Fig.10 and Fig.11 As shown, the fixing member 700 is provided with an operating portion 730, which is arranged on the side of the blocking portion 720 away from the first end plate 800. The operating portion 730 is arranged outside the accommodating space for facilitating the fixing member 700 and the electric heating component 300 connected to the fixing member 700 to be arranged in the accommodating space through the through portion 810.

[0109] like Figure 3 and Figure 4 As shown, the casing 100 includes a connecting plate 110, which is arranged opposite to the first end plate 800 along the length direction of the heat exchanger 200. The connecting plate 110 and the first end plate 800 together define a connecting cavity 120, and the side of the first end plate 800 that is away from the accommodating space faces the connecting cavity 120; wherein the operating part 730 and the blocking part 720 are located in the connecting cavity 120.

[0110] It should be noted that, in this embodiment, the motor 500 and the connecting cavity 120 are located on the same side of the housing 100 .
