Since the short side direction 38 of the short rectangular room blows out, the air in the room can be purified more effectively.

In addition, similarly, for example, in the case where the air cleaning device is arranged at a corner of a rectangular room, other corners adjacent to the above-mentioned corner 36, the third louver blowing opening 33 is closed by the shielding plate 35, The two directions of the first louver blowout opening 31 and the second louver blowout opening 32 are provided so as to be inside the room. Here, the air cleaner is installed so that the first louver blowout opening 31 blows out in the longitudinal direction of the rectangular room.

Thereby, the air from the first louver blowing opening 31 with a large air volume is blown toward the longitudinal direction 37 of the long rectangular room, and the air from the opening 32 of the second louver with a small air volume is blown toward the long side direction 37 of the long rectangular room. Since the short side direction 38 of the short rectangular room blows out, the air in the room can be purified more effectively.

In this way, since the shielding plate 35 is provided to close the air passage to the second louver blowing opening 32 or the third louver blowing opening 33, the above-mentioned advantages can also be exerted when the air cleaning device is installed at a corner of a rectangular indoor corner. As an effect, the air cleaner of this embodiment can be installed in any corner.

In addition, as shown in FIGS. 2 and 4 , the first fan outlet 25 communicates with the first main body outlet 11 through the communication path 26 . The communication passage 26 is composed of a first communication passage 27 extending horizontally from the first fan outlet to the other side of the first opposing portion of the main body case 1, and a second communication passage 28 extending downward from the first communication passage 27. . A plate-shaped wind direction plate 39 extending in the horizontal direction is provided in the second communication passage 28 .

Thus, when the first blade 21 is driven by the first motor 22, indoor air is sucked into the main body casing 1 from the first louver suction port 2A of the louver 2 through the air cleaning unit 5 provided at the first main body suction port 9. Inside. The sucked air enters the first casing 20 from the first fan inlet 24 and is blown to the wind direction plate 39 through the first fan outlet 25 , the first communication passage, the second communication passage, and the communication passage 26 . The air that hits the upper surface of the wind direction plate 39 passes along the upper surface of the wind direction plate 39 on the other side of the first opposite portion of the main body shell 1 of the wind direction plate 39 and on one side of the second opposite portion of the main body shell 1. It flows into the space 40 between the other side of the second opposing portion of the main body case 1 . That is, because the air that hits the upper surface of the wind direction plate 39 flows along the upper surface of the wind direction plate 39, it is easy to flow to the same direction as the other side of the first opposing portion of the main body case 1 in the room, and the first side of the main body case. The same direction as one side of the 2 opposing parts and the same direction as the other side of the second opposing part of the main body case.
