ABSTRACT:
The deodorizing apparatus includes a gas duct having a suction port to be disposed within a toilet bowl and an exhaust port to be disposed outside the toilet bowl, and an active carbon honeycomb and a chemical-supporting honeycomb as disposed within the gas duct in that order in the direction from the suction port to the exhaust port. The deodorizing apparatus further includes a motor operative in response to a sensor detection signal representing the user sitting on the stool seat to drive a fan disposed downstream within the gas duct, and a timer operative in response to a sensor detection signal representing the user leaving the stool seat to control the operation time of the motor. There may also be provided a damper for opening and closing the gas duct in response to the action of the fan.
