In addition, the air outlet resistance of each fresh air outlet is reduced due to the increase of the number of the fresh air outlets.
In some embodiments, as shown in fig. 1 and 2, the indoor unit of the air conditioner further includes a fresh air blower 20. The fresh air fan 20 is installed inside the casing 10 for promoting the flow of the fresh air flow. The fresh air blower 20 includes a housing 100. The housing 100 is provided with a fresh air inlet 110 for sucking in fresh air flow and a plurality of fresh air outlets 120, 130 for discharging fresh air flow. The fresh air inlet 110 can be connected to the outdoor environment through a predetermined pipeline (fresh air pipe 40) to introduce a fresh air flow. Each fresh air outlet 120, 130 is connected to a fresh air outlet 13, 14. When the indoor environment has the new trend demand, the air conditioner opens new trend fan 20, inhales new trend air current, and new trend air current discharges to the indoor environment through new trend export 120, 130 and new trend air outlet 13, 14 in proper order. Because a plurality of new trend export 120, 130 air-out simultaneously for the air-out of new trend fan 20 is more smooth and easy, and wind-force is stronger. Moreover, the quantity of the fresh air outlets is increased, and the air outlet resistance of each fresh air outlet is reduced. Under the same air quantity, the rotation speed of the fresh air fan 20 is reduced by adding the fresh air outlets 120 and 130, so that the power consumption and the noise are lower.
In some embodiments, as shown in fig. 1 and 2, the number of the fresh air outlets is two. One of the fresh air outlets 13 is located on the top surface of the casing 10 so as to supply air upwards; another fresh air outlet 14 is located in front of the casing 10 so as to supply air forwards. Correspondingly, the number of the fresh air outlets 120, 130 is two, and the fresh air outlets are respectively opened upwards and forwards so as to be respectively connected with the two fresh air outlets 13, 14. Every new trend export is connected with the mode that the new trend air outlet that corresponds meets through sealed to make the direct discharge of new trend air current to outdoor environment, can not get into all the other spaces in the casing 10, can not mix with heat transfer air current casing 10 is inside.
Further, as shown in fig. 1, the heat exchanging air inlet 11 and the heat exchanging air outlet 12 may be respectively opened on the top surface and the bottom surface of the casing 10. The fresh air outlet 13 and the heat exchange air inlet 11 located on the top surface of the casing 10 are arranged side by side along the length direction (x direction) of the casing 10, and are close to a first end of the casing 10 in the length direction (in the example in the figure, the left end of the casing 10 is the first end, and the right end is the second end). The fresh air outlet 14 located in front of the casing 10 is located at the front bottom of the casing 10 and is close to the first end of the casing 10 in the length direction. Specifically, as shown in fig. 1, the heat exchanging air inlet 11 and the heat exchanging air outlet 12 may be both long strips with the length direction parallel to the length direction of the casing 10. Under the action of a heat exchange fan (not shown), indoor air enters the casing 10 through the heat exchange air inlet 11, then exchanges heat with an evaporator (not shown) to form heat exchange air flow (cold air during refrigeration and hot air during heating), and finally the heat exchange air flows through the heat exchange air outlet 12 and is discharged to the indoor environment, so that the refrigeration or heating of the indoor environment is completed. In the embodiment of the present invention, the fresh air outlets 13 and 14 are disposed at positions close to the end of the casing 10, so that the layout of the heat exchanging air inlet 11, the heat exchanging air outlet 12, the evaporator and the heat exchanging fan is not affected.
