By the sensor mounting part 138 and the sensor support part 155, an installation space in which the sensor device 137 is installed may be defined.

The third body 153 may be positioned to be inserted into the housing inserting portion 134b formed in the upper frame 132. In summary, the third body 153 is inserted into the housing insert, and the housing cutouts 154a and 154b support upper portions of the first filter frame 135 and the sensor mounting part 138. The first filter frame 130 and the first fan housing 150 may be stably coupled.

The plurality of first filter supports 135 may be arranged in the circumferential direction along edges of the upper and lower frames 131 and 132 to support the outer circumferential surface of the first filter member 120. For example, the plurality of first filter supports 135 may be disposed at a rear portion of the first filter frame 130. In addition, an inlet portion 130b is formed at a front portion of the first filter frame 130 to provide a space in which the first filter member 120 is drawn out or drawn in.

In detail, the circumferential length L1 of the first frames 135a and 135b may be longer than the circumferential length L2 of the second frames 135c and 135d. According to this configuration, the supporting force of the first frame (135a, 135b) may be greater than the supporting force of the second frame (135c, 135d). Therefore, the supporting force which is insufficient by not providing a separate frame on the front side of the first filter frame 130 may be reinforced.

The rear side of the center C of the two angles formed by the two extension lines L2 and L3 extending from the center C to each front end of the two first frames 135a and 135b. The forming angle θ may be 180 degrees or more. That is, the front ends of the first frames 135a and 135b may further extend toward the front side with respect to the center C of the lower frame 131, thereby reinforcing the front side supporting force of the first filter frame 130. Can be.
