A drainage pump 14 for discharging is provided.

Here, the separator 3 has a shape shown in detail in FIG. 2, and is attached to the facing wall surface of the inner box 2 by a plurality of boss portions 15 by screws 16, respectively. There is a substantially uniform space between the wall surface and the back side of the ceiling of the cleaning chamber (drying chamber) 4 (the upper plate portion 3a of the separator 3) and the interior of the cleaning chamber 4 due to the space. An air supply passage 17 that passes through the back side of the (rear plate portion 3b of the separator 3) is formed. With regard to this air supply passage 17, the front end of the lower rear part is open to the inside of the cleaning chamber 4 as the air supply port 18, and the base end part of the front upper part is the ventilation port 19 formed in the inner box 2. It is in communication. An intake duct 20 arranged on the inner box 2 is communicated with the ventilation port 19, and a base end portion of the intake duct 20 is communicated with an intake port 21 formed on the front surface of the outer box 1. ..

Further, a fan 23 of the blower 22 and a casing 24 are arranged facing the ventilation port 19 at a portion of the air supply passage 17 which is located on the back side of the separator upper plate portion 3a. Is rotated by a motor 25 arranged outside the intake duct 20. Also, this air supply passage 17
