PURPOSE:To provide an automotive ventilator which is constructed to ventilate a vehicle by driving a ventilating blower means via an auxiliary battery when the temperature in the automotive room increases higher than predetermined value to prevent an automotive engine from disabling to start via a main battery. CONSTITUTION:When the temperature in an automotive room increases higher than predetermined temperature in a vehicle parked outside under sunshone ground to thereby close a bimetal switch 15, a motor 12 is energized through a manual switch 15, a normally closed contacts 21a, a bimetal switch 15, and a charged amount detector 24 from an auxiliary battery 23 to operate a ventilating fan 11. Thus, the air in the room 1 is exhausted through a passage 10 from an outlet 14. If the terminal voltage of the battery 23 decreases lower than predetermined voltage in this case, a normally open contacts 35a are reset to open state from closed state by the operation of a comparator in the detector 24 so as to prevent the battery 23 from overdischarging in advance. Reference numeral 18 indicates a main battery. |
