DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0032] The duct machine provided by the utility model embodiment is as follows Figures 1 to 4 As shown, the invention comprises: a housing 100, wherein a partition wall 110 is provided inside the housing 100, wherein the partition wall 110 divides the inside of the housing 100 into a first air duct 120 and a second air duct 130, and wherein the partition wall 110 is provided with an air outlet 111; a fan 200, wherein the fan 200 is located in the first air duct 120 and is provided at the air outlet 111, and wherein the fan 200 is provided to form an air beam flowing from the first air duct 120 through the fan 200 and the air outlet 111 to the second air duct 130; a first heat exchanger 300 and a water receiving tray 400, wherein both the first heat exchanger 300 and the water receiving tray 400 are It is arranged in the second air duct 130, the water receiving tray 400 is located at the lower side of the first heat exchanger 300, the end of the first heat exchanger 300 away from the water receiving tray 400 is adjacent to the partition wall 110, and the end adjacent to the water receiving tray 400 is away from the partition wall 110, and the air outlet 111 is facing the side of the first heat exchanger 300 adjacent to the partition wall 110; and the diverter 500, the diverter 500 is fixed between the air outlet 111 and the water receiving tray 400, and the diverter 500 is configured to divert the wind beam blown from the air outlet 111 to the end of the first heat exchanger 300 adjacent to the water receiving tray 400.

[0033] When the air duct machine is running, the wind beam blows toward the first heat exchanger 300 from the air outlet 111. The wind speed at the end of the first heat exchanger 300 near the water tray 400 is relatively high, which easily generates the sound of wind blowing the fins. In this solution, the wind beam blowing toward the end of the first heat exchanger 300 near the water tray 400 is diverted by the diverter 500, thereby reducing the wind speed at the end of the first heat exchanger 300 near the water tray 400, thereby avoiding the sound of wind blowing the fins at the end of the first heat exchanger 300 near the water tray 400. That is, during the operation of the air duct machine of this solution, there will be no sound of wind blowing the fins.

[0034] In some examples, such as Figure 3 and Figure 4 As shown, the diverter 500 is fixed to the water receiving tray 400 and is spaced apart from the first heat exchanger 300, making full use of the space between the end of the first heat exchanger 300 adjacent to the water receiving tray 400 and the partition wall 110, while preventing the diverter 500 from damaging the fins of the first heat exchanger 300.

[0035] Furthermore, if Figure 4As shown, the diverter 500 is configured as a diverter plate arranged in the horizontal direction. In this solution, the diverter plate will basically have no effect on the air output of the duct machine. Among them, the two ends of the air outlet 111 in the length direction of the water receiving tray 400 are located between the two ends of the diverter plate in the length direction of the water receiving tray 400. The wind speed in the area corresponding to the air outlet 111 at one end of the first heat exchanger 300 adjacent to the water receiving tray 400 is the largest. The two ends of the air outlet 111 in the length direction of the water receiving tray 400 are located between the two ends of the diverter plate in the length direction of the water receiving tray 400. In this way, the diverter plate can better divert the maximum wind speed area of ​​the wind beam blowing from the air outlet 111 to one end of the first heat exchanger 300 adjacent to the water receiving tray 400, and the sound of wind blowing the fins will not appear at the end of the first heat exchanger 300 adjacent to the water receiving tray 400. That is: during the operation of the duct machine of this solution, there will be no sound of wind blowing the fins.

[0036] Furthermore, if Figure 3 As shown, the diverter plate is provided with a plurality of diverter long holes 510, and the plurality of diverter long holes 510 are sequentially arranged in the length direction (i.e., left-right direction) of the water receiving tray 400, and each diverter long hole 510 extends in the width direction (i.e., front-back direction) of the water receiving tray 400. This scheme has a simple structure and is easy to manufacture. Among them, the size of each diverter long hole 510 in the length direction of the water receiving tray 400 is 8mm to 12mm, and the size of each diverter long hole 510 in the width direction of the water receiving tray 400 is 65mm to 75mm. In this way, the diverter plate has a better diverting effect on the maximum wind speed area of ​​the wind beam blowing from the air outlet 111 to the end of the first heat exchanger 300 adjacent to the water receiving tray 400, and the end of the first heat exchanger 300 adjacent to the water receiving tray 400 will not have the sound of wind blowing the fins. That is: during the operation of the air duct machine of this scheme, there will be no sound of wind blowing the fins.

[0037] Furthermore, if Figure 2 As shown, the fan 200 is configured as a centrifugal fan. The centrifugal fan, the air outlet 111 and the diverter plate may comprise a group; or the centrifugal fan, the air outlet 111 and the diverter plate may comprise a group; Figure 2 As shown, the centrifugal fan, the air outlet 111 and the diverter plate include multiple groups spaced apart in the length direction of the water receiving tray 400, and the multiple groups may be two groups, three groups or four groups, etc.; all of the above can achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present utility model, and will not be repeated here, and should all fall within the protection scope of the present application.

[0038] Furthermore, if Figure 3As shown, the water receiving tray 400 is provided with a stud 410 and a positioning portion 420, and the diverter plate is provided with a through hole and a positioning matching portion 520. The positioning matching portion 520 cooperates with the positioning portion 420 for pre-positioning, and then the screw passes through the through hole and is tightened on the stud 410 to achieve the diverter plate being firmly fixed on the water receiving tray 400. Alternatively, the diverter plate is coated with an anti-corrosion layer, so that the diverter plate is less likely to be corroded in a humid environment.

[0039] Among them, one of the positioning portion 420 and the positioning matching portion 520 is configured as a positioning groove, and the other is configured as a positioning rib, and the positioning rib is inserted into the positioning groove to achieve pre-positioning of the diverter plate on the water receiving tray 400.

[0040] Compared with a duct air conditioner without a splitter plate, the duct air conditioner provided in the present application has a larger air output at a high fan speed, which is increased by about 20 cubic meters per hour.

[0041] Fig. 9 This is the air outlet velocity distribution diagram of the fan of a duct air conditioner without a diverter plate. Fig.10 This is the air velocity distribution diagram of the fan of the duct fan with a splitter plate. It can be found that Fig.10 The wind speed of the wind beam from the fan 200 to the end (position a) of the first heat exchanger 300 adjacent to the water receiving tray 400 is reduced, so that the sound of wind blowing the fins will not occur during the operation of the air duct machine.

[0042] In some examples, such as Figure 5 and Figure 6 As shown, at the first end (such as the right end) of the length direction of the water receiving tray 400: a water treatment component is provided between the end plate of the first heat exchanger 300 and the end wall of the second air duct 130, the water treatment component includes a water pump 610 and a water level detection member 620, the end wall of the second air duct 130 includes a detachable mounting plate 630 and a detachable first inspection cover 640, the water pump 610 and the water level detection member 620 are both fixedly mounted on the mounting plate 630, and the water pump 610 and the water level detection member 620 are fixedly mounted on the mounting plate 630. The electrical connection part of the water level detection member 620 is located below the mounting plate 630, and the first inspection cover plate 640 is located below the mounting plate 630, and is adjacent to and opposite to the electrical connection parts of the water pump 610 and the water level detection member 620. In this way, the water pump 610 and the water level detection member 620 can be easily inspected by removing the first inspection cover plate 640, and the water pump 610 and the water level detection member 620 can be easily replaced by removing the mounting plate 630 and the first inspection cover plate 640. In the production process, before installing the first inspection cover plate 640, the functions of the water pump 610 and the water level detection member 620 can also be checked at the position where the first inspection cover plate 640 needs to be installed to see if they are normal, which can effectively reduce the factory failure rate of the air duct machine. Among them, the water level detection member 620 is set as a float switch.

[0043] In some examples, such as Figure 2 As shown, at the first end (such as the right end) of the length direction of the water receiving tray 400 (the length direction of the water receiving tray 400 is the second horizontal direction, and the width direction of the water receiving tray 400 is the first horizontal direction): the right end of the first heat exchanger 300 is connected with a refrigerant pipe 650, and the refrigerant pipe 650 is connected with a throttling component 660. The air duct machine also includes a detachably mounted second inspection cover plate 670, which is erected between the right end plate of the first heat exchanger 300 and the right end wall of the second air duct 130 at the front of the shell 100 and connected to the right end plate of the first heat exchanger 300 and the right end wall of the second air duct 130. The throttling component 660 is adjacent to the second inspection cover plate 670. By removing the second inspection cover plate 670, the throttling component 660 can be easily inspected and replaced. Among them, the throttling component 660 is set as an electronic expansion valve.

[0044] In some examples, such as Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the air duct machine also includes: a second heat exchanger 700, which is vertically arranged in the second air duct 130 and is located on the side of the first heat exchanger 300 that is not facing the air outlet 111, and the refrigerant pipe 650 is connected to the second heat exchanger 700; a mounting frame 800, which is provided with a first slot 810 and a second slot 820, and is arranged in the water receiving tray 400 at the end of the length direction of the water receiving tray 400, and the end of the first heat exchanger 300 is inserted into the first slot 810, and the end of the second heat exchanger 700 is inserted into the second slot 820. The mounting frame 800 limits the relative position of the first heat exchanger 300 and the second heat exchanger 700 to avoid relative misalignment of the first heat exchanger 300 and the second heat exchanger 700.

[0045] In one embodiment, if Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the mounting frame 800 includes one and is located on the left side of the first heat exchanger 300 and the second heat exchanger 700. The left end of the first heat exchanger 300 is inserted into the first slot 810, and the left end of the second heat exchanger 700 is inserted into the second slot 820. Figure 7 and Figure 8 As shown, the bottom wall of the first slot 810 is provided with a plurality of openings for passing the heat exchange tubes at the end of the first heat exchanger 300 , and the bottom wall of the second slot 820 is provided with a plurality of openings for passing the heat exchange tubes at the end of the second heat exchanger 700 .

[0046] Furthermore, if Figure 7 and Figure 8As shown, the mounting frame 800 is an integrated structure and is a plastic part. The mounting frame 800 and the first heat exchanger 300 can be connected by snap connection or screw connection, the mounting frame 800 and the second heat exchanger 700 can be connected by snap connection or screw connection, and the mounting frame 800 and the water tray 400 can be connected by snap connection or screw connection; all of the above can achieve the purpose of this application, and their purpose does not deviate from the design concept of this utility model, and will not be repeated here, and should all belong to the protection scope of this application.

[0047] In one embodiment, the mounting frame 800 is mounted on the water receiving tray 400 by snapping. Figure 2 As shown, one of the side plate of the first heat exchanger 300 and the side wall of the first slot 810 is provided with a buckle, and the other is provided with a buckle position, and the buckle is snapped into the buckle position to achieve a snap connection between the left end of the first heat exchanger 300 and the mounting frame 800; Figure 2 As shown, the side plate of the second heat exchanger 700 is provided with a screw hole, and the side wall of the second slot 820 is provided with a through hole. The screw passes through the through hole and is screwed into the screw hole to realize the screw connection between the left end of the second heat exchanger 700 and the mounting frame 800. In this solution, the assembly speed of the mounting frame 800, the water tray 400, the first heat exchanger 300 and the second heat exchanger 700 is faster and the assembly efficiency is higher.

[0048] In some examples, such as Figure 2 As shown, the duct machine also includes a partition 910, which is at the first end (such as the right end) of the length direction of the water receiving tray 400: the partition 910 is arranged on the right end plate of the first heat exchanger 300 and is connected to the partition wall 110, and the second air duct 130 forms a heat exchange air duct 131 and an installation cavity 132 on both sides of the partition 910 in the length direction of the water receiving tray 400, and the heat exchange air duct 131 is connected to the air outlet 111, and the air beam from the air outlet 111 through the heat exchange air duct 131 Blowing into the room, the installation cavity 132 is located on the right side of the heat exchange air duct 131 and is not connected to the heat exchange air duct 131. The water pump 610, the water level detection component 620, the throttling component 660 and the refrigerant pipe 650 are all located in the installation cavity 132. The fins of the first heat exchanger 300 and the second heat exchanger 700 are all located in the heat exchange air duct 131. This can not only prevent the noise in the installation cavity 132 from being transmitted to the room through the heat exchange air duct 131 with the wind beam, but also increase the air output of the duct machine. Among them, the partition 910 is a partition plate, and a sound insulation component is provided on the side of the partition plate. The sound insulation component can be a sound insulation sponge.
