[0021] The two wire outlets of the two fans are arranged to face each other, and in the horizontal direction, the first winding groove is located between the two wire outlets.

[0022] The two fan leads of the two fans are wound in the same first winding groove and the same second winding groove.

[0023] Optionally, two fan cavities are adjacently arranged in the shell, and one fan is installed in each fan cavity.

[0024] There are two first winding grooves arranged at intervals, and the fan lead wire of the fan is wound in each of the first winding grooves.

[0051] Figure 11 is a schematic front view of an indoor unit of an air conditioner according to an embodiment of the present utility model. Figure 1 As shown, and refer to Figure 2-12 The embodiment of the utility model provides an air duct assembly of an air conditioner, the air duct assembly includes a fan 100 and a housing 200. The fan 100 includes a fan body 110, a wire outlet 120 and a fan lead 130 extending from the wire outlet 120.

[0052] The housing 200 is provided with a fan cavity 210, and the fan 100 is installed in the fan cavity 210. The housing 200 is provided with a first winding groove 220 with an opening facing downward, and the top of the first winding groove 220 is lower than the outlet 120, so that the fan lead 130 is lower than the outlet 120 when passing through the first winding groove 220.

[0053] The air conditioner may be a cabinet air conditioner, a wall mounted air conditioner, etc. In this embodiment, the technical solution of the present application is described by taking the cabinet air conditioner as an example.

[0054] Exemplarily, the housing 200 is arranged vertically, and an air duct 260 is arranged in the housing 200, and a wind wheel is arranged in the air duct 260. The lower end of the wind wheel is coaxially fixedly connected with the fan 100, and the fan 100 is vertically installed in the fan cavity 210. The air duct 260 is separated from the fan cavity 210 by the bottom plate of the air duct 260 to prevent the condensed water inside the air duct 260 from directly flowing downward into the fan cavity 210.

[0055] The outlet 120 can be arranged on the side wall of the fan body 110, and the fan lead 130 is led out from the outlet 120 and finally connected to the electric control box of the air conditioner. A waterproof joint, a sealing ring, etc. can be arranged at the outlet 120 to improve the sealing performance of the fan 100.

[0056] In this embodiment, Figure 4-5 As shown, a first winding groove 220 is provided on the housing 200, the opening of the first winding groove 220 faces downward, and the top of the first winding groove 220 is lower than the outlet 120. After the fan lead 130 is led out from the outlet 120, it needs to extend downward for a distance before bypassing the first winding groove 220 and finally connecting to the electric control box. Under the action of gravity, even if condensed water is attached to the fan lead 130, it will not flow upward along the fan lead 130, thereby achieving the effect of preventing condensed water from entering the inside of the fan 100.

[0057] The first winding groove 220 may be disposed in the fan cavity 210 , for example, at the bottom of the fan cavity 210 , or may be disposed outside the fan cavity 210 , which is not limited here.

[0058] Preferably, the first winding groove 220 is integrally formed on the housing 200 .

[0059] In some embodiments of the air duct assembly of the present utility model, as Figure 2-3 As shown, the housing 200 is further provided with a second winding groove 230 with an opening facing upward, and along the lead-out direction of the fan lead wire 130 , the second winding groove 230 is located downstream of the first winding groove 220 .

[0060] The bottom end of the second winding groove 230 is higher than the top end of the first winding groove 220 , so that the fan lead wire 130 is higher than the top end of the first winding groove 220 when it passes through the second winding groove 230 .

[0061] In this embodiment, a second winding groove 230 with an upward opening is provided downstream of the first winding groove 220, and the bottom end of the second winding groove 230 is higher than the top end of the first fan lead groove 130. After the fan lead 130 bypasses the first winding groove 220, it needs to extend upward for a distance before bypassing the second winding groove 230. In other words, the fan lead 130 forms a U-shaped bend with an upward opening between the outlet 120 and the second winding groove 230. The condensed water attached to the fan lead 130 will accumulate at the lower end of the U-shaped bend under gravity and drain downward from the lower end of the U-shaped bend.

[0062] On the one hand, it can further prevent condensed water from entering the fan 100 along the fan lead 130 toward its upstream direction.

[0063] On the other hand, the drainage position of the fan lead 130 is fixed at the lower end of the U-shaped bend, and the condensed water will not flow to other positions along the fan lead 130, which facilitates the arrangement of a water receiving tray below the position.

[0064] On the other hand, when the electric control box is located at the lower side of the fan 100, condensed water can be prevented from flowing along the fan lead 130 toward the downstream direction thereof and entering the electric control box.

[0065] The second winding groove 230 may be disposed in the fan cavity 210 , for example, at the bottom of the fan cavity 210 , or may be disposed outside the fan cavity 210 , which is not limited here.

[0066] Preferably, the second winding groove 230 is integrally formed on the housing 200 .

[0067] In some embodiments of the air duct assembly of the present utility model, as Figure 4-9 As shown, the fan cavity 210 includes a wire outlet hole 211, which is opened on the peripheral wall of the fan cavity 210 and faces the wire outlet 120. Along the lead-out direction of the fan lead wire 130, the wire outlet hole 211 is located upstream of the first winding groove 220.

[0068] The lower end of the wire outlet hole 211 is lower than the wire outlet 120 and higher than the top of the first winding groove 220 .

[0069] In this embodiment, the first winding groove 220 may be disposed outside the fan cavity 210 so as not to affect the heat dissipation efficiency of the fan cavity 210 .

[0070] The fan 100 as a whole can be in the shape of a rotating body, and the fan cavity 210 is correspondingly configured as a column. A wire outlet hole 211 facing the wire outlet 120 is opened on the side wall of the fan cavity 210 near the wire outlet 120 to facilitate the fan lead wire 130 to be led out of the fan cavity 210.

[0071] The outlet hole 211 can lead the fan lead 130 out of the fan cavity 210 on the one hand, and on the other hand limit the position and direction of the fan lead 130. Specifically, the lower end of the outlet hole 211 is lower than the outlet port 120 and higher than the top of the first winding groove 220, so that the fan lead 130 can be led out from the outlet port 120, first extend horizontally or obliquely downward, pass through the outlet hole 211, and then extend obliquely downward and bypass the first winding groove 220. In this way, it can be prevented that the fan lead 130 of the outlet hole 211 is higher than the outlet port 120, causing condensed water to enter the fan 100 along the fan lead 130.

[0072] In some embodiments of the air duct assembly of the present utility model, as Figure 4-9 As shown, the housing 200 includes a front housing 201 and a rear housing 202 that are detachably fixedly connected, and the fan cavity 210 is formed by the front housing 201 and the rear housing 202 .

[0073] The wire outlet hole 211 is located at the joint between the front housing 201 and the rear housing 202 , and at least a portion of the hole wall of the front portion of the wire outlet hole 211 is located on the front housing 201 .

[0074] In this embodiment, the fan cavity 210 is formed by the front housing 201 and the rear housing 202, which can facilitate the installation of the fan 100. Specifically, during installation, the fan 100 is first installed in the fan cavity 210 of the rear housing 202, the fan lead wire 130 is led out through the outlet hole 211, and then the front housing 201 is covered on the front side of the rear housing 202.

[0075] In this embodiment, the hole wall of the outlet hole 211 is formed by the front shell 201 and the rear shell 202. In this way, when the fan 100 is installed in the partial fan cavity 210 of the rear shell 202, it is not necessary to first find the thread end of the downstream end of the fan lead 130, pass the thread end through the outlet hole 211, and then straighten the fan lead 130. It is only necessary to place the fan lead 130 on the rear hole wall of the outlet hole 211, which is easy to operate. When the front shell 201 cover is installed on the rear shell 202, the rear and front hole walls of the outlet hole 211 are surrounded, so that the fan lead 130 is in the outlet hole 211, so as to limit the position and direction of the fan lead 130.

[0076] In some embodiments of the air duct assembly of the present utility model, as Figure 6-7As shown, the front housing 201 and the rear housing 202 together form two adjacent fan cavities 210 , and a fan 100 is installed in each fan cavity 210 .

[0077] The two wire outlets 120 of the two fans 100 are arranged to face each other, and the two wire outlet holes 211 of the two fan chambers 210 are arranged to face each other.

[0078] The rear housing 202 is further provided with a wire groove 240, which is located between the two wire outlet holes 211 in the horizontal direction. One end of the wire groove 240 is connected to the two wire outlet holes 211, and the other end is an open end.

[0079] In this embodiment, the air conditioner has two air ducts 260, and the two air ducts 260 are arranged in a lateral interval. The air duct assembly has two fan chambers 210 and fans 100. The wire outlets 120 of the two fans 100 and the wire outlet holes 211 of the two fan chambers 210 are both located between the two fans 100, so that the two fan leads 130 can be arranged together.

[0080] In this embodiment, a wire groove 240 is also provided in the rear housing 202. The upper end of the wire groove 240 is located between the two wire outlet holes 211, and the lower end is open. In this way, during installation, the two fan leads 130 can be directly passed through the wire groove 240, so that the two fan leads 130 are located at the rear side of the joint between the front housing 201 and the rear housing 202. When the front housing 201 is covered on the rear housing 202, the front housing 201 will not interfere with the two fan leads 130.

[0081] After the front housing 201 is covered on the rear housing 202 , the two fan lead wires 130 are led forward from the first winding groove 220 .

[0082] Preferably, after the front housing 201 is covered on the rear housing 202 , the groove wall of the first winding groove 220 is located at the front side of the wire passing groove 240 .

[0083] In some embodiments of the air duct assembly of the present utility model, as Figure 3-4 As shown, the housing 200 includes a front housing 201 and a rear housing 202 that are detachably fixedly connected, and the fan cavity 210 is formed by the front housing 201 and the rear housing 202 .

[0084] The first winding groove 220 and the second winding groove 230 are both disposed on the front housing 201 .

[0085] In this embodiment, the first winding groove 220 and the second winding groove 230 are both arranged on the front housing 201 , which can facilitate leading out the fan lead 130 .

[0086] It should be understood that, whether it is a wall mounted air conditioner or a cabinet air conditioner, the rear housing 202 is usually close to a wall or a corner, and the operating space behind the rear housing 202 is small. If the first winding groove 220 and the second winding groove 230 are set on the rear housing 202, during installation, especially during maintenance and installation, it is not easy to wind the fan lead 130 in the first winding groove 220 and the second winding groove 230 due to the influence of the operating space and lighting conditions, which will result in low installation efficiency and easy errors.

[0087] On the other hand, the electric control box of the air conditioner is usually arranged near the front panel. The first winding groove 220 and the second winding groove 230 are arranged on the front shell 201, so that the fan lead 130 can be directly led forward, which can reduce the cable length and reduce the cost.

[0088] In some embodiments of the air duct assembly of the present utility model, as Figure 3-4 As shown, the front housing 201 and the rear housing 202 together form two adjacent fan cavities 210 , and a fan 100 is installed in each fan cavity 210 .

[0089] The two wire outlets 120 of the two fans 100 are arranged to face each other, and in the horizontal direction, the first winding groove 220 is located between the two wire outlets 120 .

[0090] The two fan leads 130 of the two fans 100 are wound in the same first winding groove 220 and the same second winding groove 230 .

[0091] In this embodiment, only one first winding groove 220 and one second winding groove 230 may be provided, thereby reducing production costs. On the other hand, during installation, after the two fan leads 130 are led out from their respective outlet holes 211, they may be first joined together and then passed around the first winding groove 220 and the second winding groove 230 together, thereby reducing installation procedures and improving installation efficiency. The two fan leads 130 may also share one line card, thereby reducing the number of line cards and reducing costs.

[0092] In some embodiments of the air duct assembly of the present invention, two fan cavities 210 are adjacently arranged in the housing 200 , and a fan 100 is installed in each fan cavity 210 .

[0093] There are two first winding grooves 220 arranged at intervals, and a fan lead wire 130 of the fan 100 is wound in each first winding groove 220 .

[0094] In this embodiment, there are two first winding grooves 220, each of which is disposed near a fan cavity 210. The fan lead wire 130 drawn from the corresponding fan 100 can be wound around the corresponding first winding groove 220 nearby, which can reduce the length of the U-shaped bend and promote the condensed water to be discharged from the lower end of the U-shaped bend as soon as possible.

[0095] In some embodiments of the air duct assembly of the present utility model, as Figure 11-12 As shown, an air duct 260 is further provided in the housing 200 , and the air duct 260 is located on the upper side of the fan cavity 210 .

[0096] A plurality of drainage holes 270 are provided at the bottom end of the air duct 260. On the horizontal projection plane, the plurality of drainage holes 270 are located on the outer side of the peripheral wall of the fan cavity 210, so that the condensed water in the air duct 260 flows through the outer side of the peripheral wall of the fan cavity 210 when being discharged downward from the drainage holes 270.

[0097] The air duct assembly further includes a water receiving tray (not shown in the figure), which is located at the lower side of the fan chamber 210. On the horizontal projection plane, the first winding groove 220 and the drainage hole 270 are both located in the water receiving tray.

[0098] In this embodiment, the plurality of drain holes 270 at the bottom of the air duct 260 are used to drain the condensed water in the air duct 260. Since the condensed water has a low temperature, when it flows downward through the fan cavity 210, it can cool the fan cavity 210 and the fan 100, thereby improving the heat dissipation efficiency of the fan 100.

[0099] In this embodiment, since the fan 100 is located at the lower side of the air duct 260, when the condensed water is discharged downward, it is easy to adhere to the fan lead 130. By providing the first winding groove 220, the condensed water can be effectively prevented from entering the fan 100 along the fan lead 130.

[0100] The water receiving tray can collect and contain condensed water flowing down from the drainage hole 270 .

[0101] Preferably, on the horizontal projection plane, the U-shaped bend of the fan lead 130 is in the water receiving tray. In this way, the condensed water flowing out from the lower end of the U-shaped bend can be collected in the water receiving tray.

[0102] In some embodiments of the air conditioner indoor unit of the utility model, the air conditioner indoor unit comprises an electric control box and an air duct assembly of any one of the above embodiments or a combination of embodiments. The fan lead wire 130 is wound out from the first winding groove 220 and then connected to the electric control box.

[0103] The electric control box is used to control the operating state of the fan 100 .

[0104] Preferably, the electric control box is located near the front panel of the indoor unit of the air conditioner and is lower than the fan 100. The fan lead 130 forms a U-shaped bend with the opening facing upward between the outlet 120 and the second winding groove 230. Condensed water attached to the fan lead 130 will accumulate at the lower end of the U-shaped bend under gravity and drain downward from the lower end of the U-shaped bend, which can prevent the condensed water from flowing downstream along the fan lead 130 and entering the electric control box.

[0105] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
