Ventilation Apparatus of Automobile Indoor Air

摘要

The present invention is, more specifically, the temperature in the vehicle room by installing the temperature-sensitive closing means which is opened and closed by a bimetal principle to the vehicle body with the interior and exterior of the vehicle a communication hole is formed to communicate with each other related to a room air ventilation device for a vehicle the high vent is to be automatically opened as relates to the outside air and the interior of the vehicle such that the temperature of the vehicle interior by heat exchange always constant and at the same time, so that ventilation with the outside air with fresh air ventilation system.; The invention, and in the automobile the communication hole formed in the outdoor and the interior of the vehicle to communicate with each other, the communication hole is formed in the vehicle body, the air temperature in the vehicle room is high when the communication hole is automatically opened by a predetermined or more to occur ventilated room of a room air ventilation device for a vehicle, it characterized in that the temperature-sensitive closing means is installed to the air temperature such that the communication hole is closed automatically falls to a predetermined or less.
