The inclined wall portion 10b is provided with air ejecting bodies 15, 16, 17 (air ejecting means, that is, air blowing means) extending in the left-right direction at intervals vertically. Moreover, each of the air dischargers 12 to 17 is provided with a plurality of air discharge ports 18 linearly arranged on the left and right. These air dischargers 12, 15 and 13, 16 and 1
Nos. 4, 17 and the like correspond to each other, and two constitute one set of air flow type water draining means.

In the apparatus body 10, the electromagnetic switching valve 19 shown in FIG. 1 (d), the electric blower 20 (electric blowing means) as the air supply means, the electromagnetic switching valve 19 and the control means for controlling the electric blower 20. A microcomputer (microcomputer) 21 and the like are incorporated. The electromagnetic switching valve 19 is
One air inflow port 19a and one air discharge port a1
a3 and a valve element (not shown) whose operation is controlled by a solenoid. The air inflow port 19a is adapted to communicate with any one of the three air ejection ports a1 to a3 by the valve body.

Moreover, the air inlet port 19a of the electromagnetic switching valve 19 has an air discharge side (air discharge port) of the electric blower 20.
Is connected to the air discharge port a1 of the electromagnetic switching valve 19, the air discharge bodies 12 and 15 are connected to it, and the air discharge port a2 of the electromagnetic switching valve 19 is connected to the air discharge bodies 13 and 16, respectively. The air discharge bodies 14 and 17 are connected to the air discharge port a3.

Further, an infrared sensor 22 is provided on the upper inclined wall portion 10a so as to be positioned below the air discharge body 14. The detection signal from this sensor 22 is sent to the microcomputer 21.
