The second separation plate 62 is characterized in that the lower end of the second separation plate 62 is inclined toward the filter upstream air passage 53 side.

As a result, the lower end of the second separation plate 62 is tilted toward the filter upstream air passage 53, so that the filter upstream air passage 53, which is the air passage from the intake port 2 to the windward surface 32a of the filter 32, It is easy to flow between the windward surface 32a, which is one side surface, and the side surface of the water storage container 21 facing the windward surface 32a, and as a result, it flows over the entire windward surface 32a of the filter 32, and the filter upstream side air passage 53 The wind flowing through the filter 32 can be efficiently passed through the filter 32.

Further, the second separation plate 62 is rotatably provided in the main body case 1 and adjusts the opening area of the communication opening 63, which has an oblong rectangular shape and communicates the filter upstream side air passage 53 and the filter downstream side air passage 54. do. In this way, by adjusting the opening area of the communication opening 63, the air flowing through the filter upstream air passage 53 can be divided into two, and the amount of air passing through the filter 32 and the amount of air not passing through the filter 32 can be adjusted. This allows you to adjust the amount of humidification.

Further, the upper end of the second separation plate 62 rotates toward the filter upstream air passage 53 side.

As a result, when the upper end of the second separating plate 62 is rotated toward the filter upstream side air passage 53, some air flows along the upper surface of the second separating plate 62, so that the filter 32 is removed from the air intake port 2. This makes it difficult for the air to flow into the air passage, and makes it easier for the air to flow from the intake port 2 to the air passage that passes through the communication opening 63 without passing through the filter 32.

Further, in a state where the upper end of the second separating plate 62 is most rotated toward the filter upstream air passage 53 side, the upper end of the second separating plate 62 is located above the center of rotation of the second separating plate 62 . As a result, when the upper end of the second separation plate 62 is rotated toward the filter upstream air passage 53, air flows more easily along the upper surface of the second separation plate 62 toward the communication opening 63, and from the air intake port 2. It becomes easier to flow into the air path passing through the communication opening 63 without passing through the filter 32.

Specifically, the first separation plate 61 has a plurality of frame portions 64 extending above the filter 32 from both horizontal ends at the lower end of the first separation plate. The lower ends of the plurality of frame portions 64 are inclined toward the filter upstream air passage 53 side. The communication opening 63 is a space surrounded by the lower end of the first separation plate 61 and a plurality of frames 64. The second separation plate 62 includes a shaft 65 and a stopper portion 66.

The second separation plate 62 has a horizontally long flat plate shape that is slightly larger than the communication opening 63 .

The shaft 65 extends from the bottom of the second separation plate 62 and from both ends in the lateral direction when the second separation plate 62 closes the communication opening 63 (the short side of the second separation plate 62 extends in the vertical direction). It has a cylindrical shape that extends outward.

When the second separation plate 62 closes the communication opening 63 (the short side of the second separation plate 62 extends in the vertical direction), the stopper part 66 is located at the lower part of the second separation plate 62 and the axis in the lateral direction. It is an elongated protrusion extending from the side toward the filter downstream air passage 54 side.

In the above configuration, when the upper end of the second separation plate 62 rotates the most toward the filter downstream air passage 54 side, the edge of the second separation plate 62 is connected to the communication opening 63 on the filter upstream air passage 53 side. The lower end of the first separation plate 61, which is the edge of the opening, contacts the plurality of frames 64. As a result, the gap between the edge of the second separation plate 62 and the lower end of the first separation plate 61, which is the opening edge of the communication opening 63 on the filter upstream side air passage 53 side, and the plurality of frames 64 is reduced. It becomes easier to flow to the wind path passing through 32.

Further, when the upper end of the second separation plate 62 rotates the most toward the filter upstream air passage 53 side, the stopper portion 66 moves between the plurality of frames that are the opening edges of the communication opening 63 on the filter downstream air passage 54 side. 64. This limits the rotation angle of the second separation plate 62 and prevents the second separation plate 62 and the filter 32 from coming into contact with each other.

The air conditioner according to the present invention is useful as an air conditioner used for home use, office use, etc.
