The first air duct 15 is connected to the first air outlet 12, and the first fan 14 is a cross-flow fan. Channel 15 is a cross-flow wind channel. The first fan 14 is disposed at the entrance of the first air duct 15 . Under the action of the first fan 14, the indoor airflow enters the first air supply column 10 through the air inlet 11, exchanges heat with the heat exchanger 17, forms a heat exchange airflow, and then enters the first air duct 15. 15 is guided to the first air outlet 12, as shown in Figure 2.

The second air supply column 20 is provided with a second air outlet 22 for blowing out purified air flow or fresh air flow. Furthermore, a second fan 24 may be provided in the second air supply column 20 , and the second fan 24 is used to urge indoor air in the second air supply column 20 to be blown out through the second air outlet 22 . The second fan 24 can be a cross-flow fan, and a second air duct 25 can be provided in the second air supply column 20, which is a cross-flow air duct, and the outlet is connected to the second air outlet 22. The second fan 24 is disposed in the second air duct. 25 entrance.

The vertical air conditioner indoor unit according to the embodiment of the present invention uses the second air supply column 20 to specifically blow out purified air flow or fresh air flow, which can make the second air supply column 20 smaller in size and configure a lower power fan (second fan 24). . When the air conditioner only operates in fresh air mode or purification mode, there is no need to turn on the first fan 14 with a relatively large power, making the energy efficiency of the vertical air conditioner indoor unit higher.

In some embodiments, the vertical air conditioning indoor unit further includes a downdraft fan 80 . The downdraft fan 80 is located in the bottom column 30 to urge the purified air flow or fresh air flow discharged from the water washing module 70 to enter the second air supply column 20 . As shown in Figure 5, the downdraft fan 80 can be a centrifugal fan with an axis extending in the vertical direction. It is arranged directly above the water washing module 70 with the inlet facing downward, so as to inhale the purified air flow or fresh air flow discharged from the water washing module 70, and then Radial discharge. The downdraft fan 80 also includes an air duct 81, the outlet of the air duct 81 is connected to the bottom inlet of the second air supply column 20, so as to introduce the purified air flow or fresh air flow into the second air supply column 20.

The front and rear of the air induction interval 13 are connected to the indoor environment, so that when the first air outlet 12 and/or the second air outlet 22 discharge air, the indoor air in the air induction interval is driven forward by negative pressure. "Horizontal" has been marked in the figure, and the vertical air conditioner indoor unit The left-right direction that is perpendicular to the front-to-back direction is the "lateral direction."

When the first air outlet 12 and/or the second air outlet 22 discharges air, the negative pressure is used to drive the indoor air in the air induction interval 13 to flow forward, so that the indoor air behind the indoor unit of the vertical air conditioner passes through the air induction interval 13 It flows forward to mix with the outlet airflow of the first air supply column 10 or the second air supply column 20 to form a diversion and air mixing effect. The temperature of the mixed air flow is closer to room temperature than the heat exchange air flow, and the comfort is higher, the wind feels softer, the air volume and wind speed are increased, and the air supply distance is farther. Especially when the second air supply column 20 also blows out indoor air, this results in a larger mixing volume and faster mixing speed of indoor air, achieving a stronger air mixing effect and bringing the air flow closer to room temperature.

The first air guide component 16 and the second air guide component 26 can each be one or more vertical strip-shaped air guide vanes, which can rotate around a vertical axis so as to rotate to the air guide position or the closed position.

The vertical air conditioner indoor unit can change the angle between the purified air flow or fresh air flow and the heat exchange air flow by adjusting the air outlet direction of the first air outlet 12 and/or the second air outlet 22, thereby changing the intersection position of the two. Specifically, the larger the angle between the direction of the purified air flow or the fresh air flow and the direction of the heat exchange air flow, the closer the intersection position is, that is, closer to the vertical air conditioner indoor unit; the smaller the angle is, the farther the intersection position is, that is, the farther away it is. Vertical air conditioner indoor unit. The vertical air conditioner indoor unit can adjust the aforementioned intersection position according to the position of the human body to avoid the intersection position being close to the human body and causing discomfort to the human body.

In addition, as shown in FIG. 2 , the vertical air conditioner indoor unit may further include an upper connection shell 40 , and the top ends of the first air supply column 10 and the second air supply column 20 are both connected to the upper connection shell 40 .
