Title:
VENTILATOR
Document Type and Number:
Japanese Patent JP2002277008
Kind Code:
A
Abstract:
To reduce cost by commonization of a circuit board.
A ventilator comprises a CO2 sensor 106 for detecting a CO2 concentration in a room, and a gas sensor 107 for detecting a gas concentration in the room on the circuit board 2 contained in a ventilator body. The ventilator further comprises a slide type selection switch 6 for arbitrarily selecting the sensor 106 and the sensor 107 to be operable on the circuit board 2. The switch 6 can be used even for gas sensing as for detecting the CO2 or further for sensing (the CO2+ the gas) by switching the switch 6 on one circuit board 2.
