Title:
HAND DRYING DEVICE
Document Type and Number:
Japanese Patent JPH1147032
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent large operation noise from occurring at the time of putting- out a hand to a blow port by increasing a voltage to be applied to a motor- driven blower step by step when it is recognized that the hand is inserted into a drying room by means of a sensor signal and slowly starting the operation of the motor-driven blower. SOLUTION: An injecting hole for injecting the blow air stream of the motor- driven blower 1 from a circulation flow path to the drying room 4 at high speed is provided in an opening part where the hand is inserted on the front surface of the drying room 4. The high-speed air stream is injected to the drying room 4 and, after that, returned from an inhale port in the depth of the drying room 5 to the motor-driven blower 1 through the circulation flow path at an inhale side. A sensor is constituted of light emitting elements 12a and light receiving elements 13a provided in the drying room 4. The slow start means of a control means 20 applies the gradually increased voltage to the motor- driven blower 1 when the sensor detects that the hand is inserted to the drying room 4 and a normal operation means adopts the voltage to be applied to the motor-driven blower 1 at the point of time when the operation of the slow start means is ended as a prescribed voltage.
