This arrangement enables the second column casing 20 to blow out fresh air or room air in a controlled manner. Of course, the fresh air inlet 43 and the indoor air inlet 44 can communicate with the air inlet of the induced draft fan 41 at the same time.

In some embodiments of the present utility model, the functional module 42 is a purification module and/or a humidification module. This setting enables the induced draft fan 41 to not only inhale fresh air, but also to inhale indoor air, achieving the effect of killing two birds with one stone.

Of course, the third airflow can also be one or more of indoor air, fresh air flow, purified airflow, humidified airflow or water washing airflow.

In some embodiments of the present utility model, the front wall of the third column housing 30 is spaced apart from the rear wall of the second column housing 20, so that the gas behind the vertical air conditioner indoor unit passes through the second column housing 20 and the third column housing 20. The space between the column housing 30 enters the air-inducing space 16 .

In some embodiments of the present invention, the front wall of the third column housing 30 is parallel to the rear wall of the second column housing 20 . One vertical edge near the first column housing 10 of the front wall of the third column housing 30 is in front of the other vertical edge, so that the space formed between the second column housing 20 and the third column housing 30 is compatible with the induced draft. Space 16 is at an obtuse angle. The front wall of the third column casing 30 is parallel to the rear wall of the second column casing 20, and the space formed between the second column casing 20 and the third column casing 30 is at an obtuse angle to the air-inducing space 16, so that the vertical air conditioner indoor unit When the air at the rear enters the air-inducing space 16 through the space between the second column shell 20 and the third column shell 30, the resistance is the smallest, which is beneficial to increase the air volume of the air-mixing airflow.

In some embodiments of the present utility model, the third column shell 30 is in contact with the first column shell 10, or the third column shell 30 is connected to the first column shell 10, so as to prevent air flow from the first column shell 10 and the third column shell. Between the shells 30 enter the air-inducing space 16 .

In some embodiments of the present utility model, when the first column housing 10 has a first air inlet 13 on the rear portion of the side wall close to the second column housing 20 , the connection between the third column housing 30 and the first column housing 10 The gap defines an air intake space that decreases from the rear to the front and communicates with the first air intake 13 . The projection of the air intake space on the horizontal plane is a triangle, the side wall of the third column shell 30 and the side wall of the first column shell 10 for defining the air intake space are at the front apex of the triangle and Both sides of a vertical plane perpendicular to the transverse direction. This arrangement makes the air intake space a wind gathering space that is reduced from the rear to the front, which is beneficial for the air inside to enter through the first air inlet 13 on the side of the first column shell 10 close to the third column shell 30 .

In some embodiments of the present invention, as shown in FIG. 5 , a vertical strip-shaped air duct 28 connecting the second air inlet and the second air outlet 21 is arranged in the second column shell 20, and the air flow entering the air duct 28 is the second airflow. Further, the distance between the two lateral side walls of the air duct in the second column shell 20 gradually decreases from the back to the front, forming a tapered shape. The air passage in the second column housing 20 is tapered, which increases the wind speed of the second air outlet 21 , which is beneficial for the second column housing 20 to send air to a distant place.

In some embodiments of the present utility model, a plurality of guide vanes 25 arranged vertically are arranged in the air duct 28, each guide vane 25 extends from front to back, and the rear end is bent downward to form a guide bend. The folding portion 251, and the higher the position of the guide vane 25, the greater the distance between the front end and the rear end. The second airflow flows from bottom to top, and after encountering each flow guide vane 25, it is guided by its flow guide bending portion 251, and gradually changes from upward flow to forward flow. Therefore, the air guide bending portion 251 plays a role in changing the direction of the airflow, so that the airflow turns more gently and the wind loss is smaller. There is a rounded transition between the guide bending portion 251 and the rest of the guide vane 25 .

Further, considering that the second airflow enters the second column housing 20 from the bottom of the second column housing 20 , the air volume at the middle or upper part of the second air outlet 21 may be relatively small. Therefore, in the embodiment of the present utility model, a plurality of guide vanes 25 arranged vertically are arranged in the second column shell 20, and the distance between the front and rear ends of the guide vanes 25 that are located higher is greater, so that the second outlet The air outlets of the tuyere 21 are more evenly distributed everywhere in the vertical direction.

In some embodiments of the present invention, the second column housing 20 is installed with an air guide for guiding the horizontal air outlet direction of the second air outlet 21 . "Guiding the horizontal air outlet direction" refers to changing the angle between the air outlet direction and the front-to-back direction, for example, making the second airflow blow toward the front, to the left, to the right, and so on. In addition, an air deflector for guiding the first air outlet 11 in a transverse air outlet direction is mounted on the first column housing 10 .

As shown in Figures 6 to 10, the vertical air conditioner indoor unit can be configured to: use the air guide 27 to adjust the horizontal direction of the wind from the second air outlet 21, so that the second airflow can merge into the first airflow from the first air outlet 11 . That is, when the air guide plate changes the outlet direction of the first air flow, the air guide member 27 is controlled to move so as to ensure that the second air flow can always merge into the first air flow. For example, as shown in FIG. 8 , when the wind deflector swings forward, the wind guide member 27 guides the wind forward. As shown in FIG. 6 , when the wind guide plate swings to the left, the wind guide member 27 guides the wind to the left.
