PURPOSE: To obtain a ventilating system capable of a symbiotic operation with the nature without generating noise or low frequency by a simple apparatus by connecting a pipe communicating with the exterior and a room at a wall, coupling it with the cover of an illuminator, communicating with the space in the cover and the pipe, and providing a vent port connected to the room at the cover. CONSTITUTION: A pipe 4a introduces the atmosphere in communication with a wall. Rock wool or glass wool is installed in the pipe 4a as substance for absorbing sound or silencing, and a unit 6 for controlling the flow of the air on one direction is installed. The unit 6 so sets a valve 8 and a support 9 that the air flows in the direction from 7b to 7a, and a cover 12 is so mounted at the wall as to direct down. A pipe 4b is mounted perpendicularly to the pipe 4a, and a unit 8 for warming the air such as a band heater is installed therein. The cover 12 is set to the upper part of the pipe 4b, a bulb 13 is provided therein and an opening 14 is provided at the upper part. |
