<P>PROBLEM TO BE SOLVED: To provide a ventilator capable of improving cleaning performance by eliminating irregularities and gaps of a switch operation part for setting an operation mode, preventing deterioration of operability owing to intrusion of oil, and having high quality design by applying a dielectric half mirror treatment giving an appearance similar to a metal on the surface of the switch operation part. <P>SOLUTION: The ventilator is equipped with a half mirror operation face 22 formed of a light transmitting insulator 7 and a dielectric half mirror 9 at the front face of the operation switch part 6 for setting the operation of a blower 2, an electrode 11 for detecting the human body at the back side of the half mirror operation face 22, and a light emitting diode 14 for displaying the operation state of the ventilator at the back side of the electrode 11. By making the operation face 22 flat, the cleaning performance can be improved, and the degree of freedom in design of the operation switch part 6 can be improved by substantializing the dielectric half mirror operation face. <P>COPYRIGHT: (C)2007,JPO&INPIT |
