PURPOSE:To perform the water draining smoothly and reliably by providing a cover unit which covers the trap section of the drain collector which discharges the drain water that overflows so that the effect of difference in the static pressure between the inside and outside of the main body of the device may be avoided. CONSTITUTION:Even when a difference in the static pressure between the inside and outside of the main body of the device is generated as the static pressure in the sealed chamber rises on account of the blowing operation of fan, the drain pipe 10 one end of which is connected to the drain pan 9 in the main body and the other end thereof to the drain collector 11 with the drain trap section 14 of the drain collector 11 to be covered by a cover unit 16. By this constitution, the water collected in the drain pan 9 from the trap section 14 of the drain collector 11 smoothly drains to the outside through the drain pipe 10 without being affected by the difference in the static pressure between the inside and outside of the main body of the device. Further, because water splash at the inlet of the drain pipe 10 is prevented, water leakage due to a sudden rise of drain water level in the drain pin 9 can be positively prevented. |
