Hand drier control apparatus
First Claim
1. A hand drier control apparatus to be mounted on a wall comprising:
- a ventilating duct having an outlet for air,an electric fan attached to the ventilating duct for producing a current of air flowing toward a user through the outlet when actuated,an electric heater attached to the ventilating duct for heating air flowing toward the user by the electric fan when actuated,non-contact detecting means for detecting a first object to be detected within a first detecting range and for detecting a second object to be detected within a second detecting range, said first detecting range being located below and relatively close to the outlet, and said second detecting range being located below the outlet and adjacent to the first detecting range, said second detecting range being located away from the outlet more than the first detecting range, anda control circuit for actuating the electric heater when the detecting means detects the first object within the first detecting range, and actuating the electric fan when the detecting means detects the second object within the second detecting range.

Abstract
The present invention is a warm-air machine control apparatus which is capable of blowing warm air from the beginning of the delivery of air without preheating an electric heater, and which comprises an electric fan (4), an electric heater (5) which heats air sent from the electric fan (4), a detector (7) which detects a first object to be detected within a first detecting range (a, c) and which also detects a second object to be detected within a second detecting range (b, d), and a control circuit which energizes the electric heater (5) when the detector (7) detects the first object of detection within the first detecting range (a, c), and which energizes the electric fan (4) when the detector (7) detects the second object of detection within the second detecting range (b, d).
