The drain container 8 is provided with a removable lid 9. In the position corresponding to the drain outlet 7 of the water receiving portion 6 of the lid 9, it is obstructed to visually recognize the drain container 8 from the drain outlet 7, and forwardly tilts to guide the water from the drain outlet 7 into the drain container 8. A receiving port having the inclined piece 10 is formed. The inclined piece 10 improves the usability because the user cannot see the sewage in the drain container 8. The drain container 8 and the lid 9 are made of chemically resistant ABS resin, and can be cleaned and cleaned using a neutral detergent, alcohol, or the like. In addition, the surface of the hand insertion portion 3 is impregnated with a water-repellent coating such as silicon or fluorine, or a hydrophilic coating such as titanium oxide, or an antibacterial agent, thereby reducing the adhesion of dirt to the surface and bacteria. Reducing breeding is being attempted.

  The high-pressure airflow generator 2 includes a DC brushless motor (which may be a normal commutator motor or an induction motor), a drive circuit that drives the DC brushless motor, and a turbo fan that is rotated by the DC brushless motor. In the embodiment, the main body box 1 is mounted directly above the hand insertion portion 3 with the intake side as the base 4 side. The intake side of the high-pressure airflow generator 2 faces an intake passage 11 having an open lower end provided in the vertical direction on the back side of the main body box 1 in the vicinity of the back side of the hand insertion portion 3. Air can be sucked from an air inlet 12 at the lower end of the passage 11 through an air filter 13 with a frame that can be attached and detached by inserting and removing in the front-rear direction.

  The front part of the frame part of the air filter 13 is formed in a wide planar form as the receiving surface 14. A barrier 15 that separates the filter medium side is provided below the receiving surface 14 in a hanging shape, and the shape of the frame is asymmetrical.
