<p>PURPOSE:To shorten detection waiting time of an airflow detector in an air- conditioner for vehicle employing a heat receiving plate heating type sensor. CONSTITUTION:The airflow detector comprises an airflow sensor comprising a heat receiving plate 1, a heater 2 for heating the plate 1, and a temperature sensitive element 3 for detecting the temperature of the plate 1, and a voltage control means 4. The voltage control means 4 applies a voltage higher than a predetermined level to the heater 2 in response to application of power supply and the applies a voltage of predetermined level to the heater. This constitution quickens temperature rise of the heat receiving plate thus shortening the detection waiting time.</p> |
