Heater 200.

When the above-mentioned air duct machine 10 is in use, the outdoor fresh air enters the housing 100 along the fresh air port 132 under the action of the fan 300; Under the action of the outdoor fresh air and indoor air blowing to the heat exchanger 200 for heat exchange, in this way, when the heat-exchanged air is discharged into the room, the loss of heat exchange with the indoor air can be reduced, and the quality of the indoor air can be improved at the same time; Since the fresh air plate 130 or the return air plate 120 is arranged vertically at the air inlet end of the fan 300 in the traditional air duct machine 10, when the fan 300 sucks air, the fresh air or indoor air is easily blocked by the casing of the fan 300, so Affects the suction efficiency and air volume of the fan 300, and will generate a certain amount of noise. In this application, the fan 300 is installed obliquely relative to the fresh air plate 130 and the return air plate 120, and the air inlets of the fan 300 are all facing the fresh air plate 130 and the return air plate. 120. At this time, outdoor fresh air and indoor air are more likely to enter the air inlet of the fan 300, which is beneficial to improve the air suction efficiency and air suction volume of the fan 300.

As shown in Figure 3, on the basis of the above embodiments, the housing 100 also includes an air outlet plate 110, the fresh air plate 130 and the return air plate 120 are fixed on the side wall of the air outlet plate 110, and the fresh air plate 130, the return air The plates 120 and the air outlet plates 110 are arranged at an angle, and the air outlet plates 110 are provided with air outlets 112, so that the air after heat exchange by the heat exchanger 200 is discharged into the room through the air outlets 112.

As shown in Figure 2, on the basis of any of the above-mentioned embodiments, since the air duct machine 10 is installed in a concealed manner, only the air exhaust port 112 and the return air port 122 are exposed, so in this embodiment, the fan 300 and the exchange The heat exchanger 200 is arranged along the length direction of the housing 100, the fan 300 is arranged between the fresh air plate 130 and the heat exchanger 200, and the projection of the fan 300 and the heat exchanger 200 on the fresh air plate 132 along the length direction of the housing 100 There is an overlapping portion, so the fan 300 and the heat exchanger 200 are relatively compact in the width direction, thereby reducing the width of the casing 100; when the air duct machine 10 is installed on the base, there are fewer parts extending into the base, and thus Conducive to later repair and maintenance. It should be pointed out that, in the length direction, among the dimensions in the housing 100 , the dimension with a larger length value is long, and the dimension not greater than the value or at the "side" is wide.

As shown in Figure 2 and Figure 3, on the basis of any of the above-mentioned embodiments, in order to smoothly blow the outdoor fresh air and indoor air to the heat exchanger 200 for heat exchange, the air duct machine 10 also includes an air guide 400 , the air guide member 400 is provided with an air guide channel 410 for guiding the airflow along the air outlet of the fan 300 to the air inlet end of the heat exchanger 200, so that through the guide of the air guide channel 410, along the outlet of the fan 300 The wind discharged from the tuyere is more easily blown to the heat exchanger 200. In this embodiment, since the air outlet of the fan 300 faces away from the return air plate 120 and is in the same direction as the air inlet end of the heat exchanger 200, they are all oriented towards the return air. The mounting plate 140 opposite to the plate 120, the wind discharged along the air outlet of the fan 300 is likely to collide with the mounting plate 140, affecting the transmission of the wind. It is easier to blow to the heat exchanger 200. In this embodiment, the casing 100 further includes a top plate 150 , and the casing 100 is surrounded by the top plate 150 , the air outlet plate 110 , two fresh air panels 130 and the return air panel 120 .
