Further, a second fan 24 may be disposed in the second air supply column 20, and the second fan 24 is configured to promote the indoor air in the second air supply column 20 to be blown out through the second air outlet 22. The second fan 24 may be a cross-flow fan, the second air supply column 20 may have a second air duct 25 disposed therein, the second air duct is a cross-flow air duct, an outlet of the second air duct is connected to the second air outlet 22, and the second fan 24 is disposed at an inlet of the second air duct 25.
In the vertical air conditioner indoor unit of the embodiment of the invention, the second air supply column 20 is used for specially blowing out purified air flow or fresh air flow, so that the volume of the second air supply column 20 is smaller, and a fan (a second fan 24) with lower power is configured. When the air conditioner only operates in a fresh air mode or a purification mode, the first fan 14 with relatively high power does not need to be started, so that the energy efficiency of the indoor unit of the vertical air conditioner is higher.
In some embodiments, the indoor unit of a floor type air conditioner further includes a lower fan 80. The lower fan 80 is positioned within the bottom pillar 30 to force the purified or fresh air stream exiting the water wash module 70 into the second air supply pillar 20. As shown in fig. 5, the lower fan 80 may be a centrifugal fan extending in a vertical direction along an axis, and is disposed right above the water washing module 70 with an inlet facing downward so as to suck the purified air flow or the fresh air flow discharged from the water washing module 70 and then discharge it in a radial direction. The lower fan 80 further comprises an air duct 81, and an outlet of the air duct 81 is connected to a bottom inlet of the second air supply column 20 so as to introduce the purified air flow or the fresh air flow into the second air supply column 20.
In some embodiments, the first air supply column 10 is provided with a first air outlet 12 opened forward, and the second air supply column 20 is provided with a second air outlet 22 opened forward, so as to allow the purified air flow or the fresh air flow and the heat exchange air flow to be mixed in front of the vertical air conditioner indoor unit, so as to form a mixed air flow, wherein the temperature of the mixed air flow is closer to the room temperature than the heat exchange air flow, the comfort is higher, the wind sensation is softer, the air volume and the wind speed are increased, and the air supply distance is longer. And the purified air flow or the fresh air flow can be mixed with the heat exchange air flow more early, so that the mixing rate is enhanced, and the purified air flow or the fresh air flow can be better diffused to various places indoors.
Further, as shown in fig. 2, the second air delivery pillar 20 and the first air delivery pillar 10 may be arranged in the lateral direction, and an air introducing space 13 may be formed therebetween. The front and the rear of the air inducing interval 13 are communicated with the indoor environment, so that when the first air outlet 12 and/or the second air outlet 22 are exhausted, the indoor air in the air inducing interval is driven to flow forwards under the action of negative pressure. The "lateral direction" is indicated in the drawings, and the left-right direction perpendicular to the front-rear direction of the indoor unit of the floor air conditioner is the "lateral direction".
When the air is discharged from the first air outlet 12 and/or the second air outlet 22, the indoor air in the induced air interval 13 is driven to flow forward by the negative pressure effect, so that the indoor air at the rear of the vertical air conditioner indoor unit flows forward through the induced air interval 13 to be mixed with the air outlet flow of the first air supply column 10 or the second air supply column 20, and a flow guiding and air mixing effect is formed. Compared with heat exchange airflow, the temperature of the mixed air flow is closer to the room temperature, the comfort is higher, the wind sense is softer, the air quantity and the air speed are increased, and the air supply distance is longer. Particularly, when the second blowing columns 20 also blow out the indoor air, the mixing amount of the indoor air is larger, the mixing speed is higher, a stronger air mixing effect can be realized, and the airflow is closer to the room temperature.
As shown in fig. 2, a second air guiding member 26 for guiding the air outlet direction of the second outlet 22 is mounted on the second air supply column 20. "directing the lateral wind direction" refers to changing the angle between the wind direction and the front-back direction, for example, blowing the wind forward right, forward left, forward right, and so on. In addition, a first air guiding component 16 for guiding the transverse air outlet direction of the first air outlet 12 is mounted on the first air supply column 10. In addition, the first air guiding member 16 may be used to close the first outlet 12, and the second air guiding member 26 may be used to close the second outlet 22. The first wind-guiding component 16 and the second wind-guiding component 26 may be one or more vertical strips of wind-guiding blades, which can rotate around a vertical axis so as to rotate to a wind-guiding position or a closed position.
The vertical air conditioner indoor unit can change the included angle between the purified air flow or the 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, and further change the intersection position of the purified air flow or the fresh air flow and the heat exchange air flow. Specifically, the larger the included angle between the wind direction of the purified air flow or the fresh air flow and the wind direction of the heat exchange air flow is, the closer the intersection position is, that is, the closer to the indoor unit of the vertical air conditioner is; the smaller the included angle is, the farther the intersection position is, namely, the farther away the vertical air conditioner indoor unit is. The vertical air-conditioning indoor unit can adjust the intersection position according to the position of a human body so as to avoid the intersection position from approaching the human body and bringing discomfort to the human body.
In addition, as shown in fig. 2, the vertical air conditioning indoor unit may further include an upper connection case 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 case 40. The first air supply column 10 and the upper connecting casing 40 may be formed as an integral piece, or the second air supply column 20 and the upper connecting casing 40 may be formed as an integral piece. By arranging the upper connecting shell 40, the structure of the vertical air conditioner indoor unit is more stable, and the appearance is more harmonious.
