Title: Control device for automatic ventilation fan
Inventor: SAKAHARA TAKASHI
IPC: F24F7/007
Filed: 1986-03-12
Abstract: PURPOSE:To reduce the number of component parts and decrease an electrical current in a circuit by a method wherein a concentration of reducing gas and a heat of atmosphere are detected by a gas detecting element and a thermal sensing element, and a modified wave sensed signal is outputted through a single non-stable multi-vibrator circuit in response to a change in these resistance values. CONSTITUTION:A change in resistance value of a gas sensing element 1 is converted into a change in DC current through a circuit 2, changed into ON time of a rectangular wave through a circuit 3 and then inputted into a computer 4. If a concentration of reducing gas is increased, a resistance value of an element 1 is decreased, and ON time of the rectangular wave is shortened. When this rate of change is increased to more than the desired value, the computer 4 may operate a switching element 5 so as to drive a motor 6. A change in of resistance value of a thermal sensing element 7 is changed into OFF time of rectangular wave through the circuit 3 and then inputted into the computer 4. As a temperature is increased, a resistance value of the element 7 is decreased, and OFF time of the computer 4 is shortened. As this rate of variation is increased more than the desired value, the computer 4 may operate the element 5 and drive the motor 6.
