Abstract

PURPOSE:To give an alarm to a user when ventilation goes poor, by a method wherein a current value of a ventilation fan corresponding to a quantity of air causing bad ventilation is determined as a breaking current value of a current breaker. CONSTITUTION:It happens that a static pressure P1 generated by the effect of outside air acts on a ventilation fan and this causes bad ventilation, under the condition that, a contact 6 being made, s fan motor 7 of the ventilation fan is operated to discharge an exhaust gas automatically. Assuming that a quantity Q1 of air at a time point 21 causes bad ventilation, a current value of a current breaker 8 is set to accord with a current I1 at a time point 22. Then a current is interrupted at this time point. Consequently, a base current of a transistor 10 stops flowing, the transistor 10 stops operation, a current flows through a gate of a thyristor 14, and thereby the thyristor 14 is operated to make sound an alarm buzzer 16 connected to the anode thereof and, simultaneously, to make a light-emitting diode 17 emit a light. Thus, a user can be informed of the poor ventilation.
