It should be noted that the description of "first", "second", etc. referred to in the embodiments of the present invention is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
Referring to fig. 5, in an embodiment, the purge inlet 15 is provided with a second air door 22, and the second air door 22 can open or close the purge inlet 15; and/or, the purification air outlet 16 is provided with a third air door 23, and the third air door 23 can open or close the purification air outlet 16. It should be noted that the meaning of "and/or" appearing throughout is to include three juxtaposed aspects, exemplified by "a and/or B", including either aspect a, aspect B, or aspects where both aspects a and B are satisfied.
The second damper 22 can be used to open or close the purge air inlet 15 to adjust the air output of the purge air outlet 16. The third damper 23 can be used to open or close the purge air outlet 16 to control the flow direction of the air flow, i.e., the flow direction of the air flow in the connecting channel 17.
Specifically, motors may be respectively disposed at the purge air inlet 15 and the purge air outlet 16 to respectively drive the second damper 22 and the third damper 23 to open and close. In addition, the second damper 22 is provided on the air-out side of the purge fan 41, i.e., between the purge fan 41 and the purge module 42. The second air door 22 can be rotatably connected with the casing 10, and when the second air door 22 is in an up-and-down extending state, the purification air inlet 15 is closed; when the second damper 22 is rotated upward, the purge air intake 15 is opened. In other embodiments, the second damper 22 may be disposed on the air intake side of the purge fan 41.
In one embodiment, the first damper 21 is disposed corresponding to the main passage 171 to open or close the main passage 171, and when the main passage 171 is open, the first branch 172 and the second branch 173 are both communicated with the purge air duct 14.
As shown in fig. 3, when the first damper 21 in fig. 3 is opened and the third damper 23 is opened, since the air pressure at the purge air outlet 16 is low, part of the air flow in the heat exchange air duct 13 flows to the purge air duct 14 and then flows out from the purge air outlet 16, so that the purge air outlet 16 blows out cold air or hot air. Specifically, a portion of the airflow flows into the purge air duct 14 from the first branch 172, and flows out of the purge air outlet 16 after being purged by the purge module 42. Another part of the air flow flows into the purge air duct 14 from the second branch 173 and directly out of the purge air outlet 16. In the process, when the second damper 22 is opened, the indoor airflow can also enter the purge air duct 14 from the purge air inlet 15, and is purged by the purge module 42 and then blown out from the purge air outlet 16. At this time, since the airflow in the purge air duct 14 is a mixture of two airflows, the airflow in the purge air duct 14 is increased, more airflow is purged, and the airflow blown out from the purge air outlet 16 is more, which is equivalent to blowing out strong wind from the purge air outlet 16. In this process, when the second damper 22 is closed, the airflow blown out from the purge air outlet 16 is totally branched from the heat exchange air duct 13, and the air output of the purge air outlet 16 is less, that is, the blown air is weak air. The controller of the indoor unit of the air conditioner can control the second damper 22 to open or close so as to switch the outlet air of the clean outlet 16 between strong air and weak air. Meanwhile, in the process, the other part of the air flow in the heat exchange air duct 13 is blown out from the heat exchange air outlet 12.
When the third damper 23 is closed and the second damper 22 is opened, the air flow in the purge air duct 14 flows to the heat exchange air duct 13 through the connecting passage 17. Specifically, the air flow enters the purge air duct 14 from the purge air inlet 15, a part of the air flow in the purge air duct 14 directly flows from the first branch 172 to the heat exchange air duct 13, and another part of the air flow is purified by the purification module 42 and then flows from the second branch 173 to the heat exchange air duct 13. All the air flow in the purifying air duct 14 is mixed with the air flow entering from the heat exchange air inlet 11 in the heat exchange air duct 13 and finally blown out from the heat exchange air outlet 12.
As shown in fig. 4, the first damper 21 in fig. 4 is closed, and at this time, the connection channel is disconnected, and the heat exchange air duct and the purification air duct are two independent channels that are not communicated with each other.
In one embodiment, the first damper 21 in the housing 10 can selectively close the first branch 172 and the second branch 173. Specifically, the first damper 21 is movably connected with the cabinet 10 to be able to have at least a first position, a second position, and a third position. In the first position, the first damper 21 opens the first branch 172 and closes the second branch 173, and when the third damper 23 is opened, part of the air in the heat exchange air duct 13 flows from the first branch 172 into the purge air duct 14. In the second position, the first damper 21 closes the first branch 172 and opens the second branch 173, and when the third damper 23 is closed and the second damper 22 is opened, the air flow in the purge air duct 14 flows from the second branch 173 into the heat exchange air duct 13. In the third position, the first damper 21 simultaneously closes the first branch 172 and the second branch 173. In this embodiment, after the first damper 21 is provided, the first damper 21 can be controlled to move as required, and the first branch 172 and the second branch 173 can be switched.
In an embodiment, the indoor air-conditioner unit is a floor-type indoor air-conditioner unit, the floor-type indoor air-conditioner unit has the casing 10, and the heat exchange air duct 13 and the purification air duct 14 are distributed in the vertical direction.

Specifically, in one embodiment, the housing 10 includes an upper housing and a lower housing, the upper housing and the lower housing are two-part housings formed separately, and the two-part housings are assembled together to form a whole. A heat exchange air duct 13 is formed in the upper shell, and a purification air duct 14 is formed in the lower shell. Of course, in other embodiments, the casing 10 may also be a single integral casing extending in the up-down direction, i.e. the upper casing and the lower casing are integrally formed. By arranging the heat exchange air duct 13 and the purification air duct 14 in the vertical direction, the space of the floor type air conditioner indoor unit can be fully utilized, and arrangement of the two air ducts is facilitated. In addition, the casing 10 may also include an inner casing and an outer casing, the inner casing being located inside the outer casing, and the inner casing forming the heat exchange air duct 13 and the purge air duct 14.
Optionally, the connecting channel 17 is disposed between the bottom of the heat exchange air duct 13 and the top of the purge air duct 14, so that the connecting channel 17 has a short length to facilitate rapid airflow.
