Abstract

PURPOSE:To provide a ventilation device such that an one-way valve can surely seal an inner air outlet port by a simple construction when the inner air outlet port is not opened by closing said port in such a manner that the one-way valve is fixed to the periphery of said port by magnetic forces. CONSTITUTION:An one-way valve 2 is connected to an area of an inclined wall surface, one end 20 of which forms an inner air outlet port 15, i.e., a vertical wall surface 130 of a periphery 13, so that the port 15 can be opened only when the inner air 14 in a wheel room 12 is discharged to the outside 17. The other end 21 of the valve 2 comes near a valve seat 13a and makes contact with it, while the valve 2 pivots on the end 20 under its own weight to close the port 15 in a direction shown by an arrow S1 and at the same time a rubber magnet is fixed to the seat 13a by magnetic forces so that the valve 2 closes the port 15. And when the pressure difference between the room 12 and the outside 17 has exceeded the forces of the magnet and the own weight, the end 21 is detached from the seat 13a, while the valve 2 pivots on the end 20, so that the end 21 is moved in a direction S2 to open the port 15.

One end of the one-way valve is connected to a wall surface forming an inside air outlet of the duct, and the other end is swingable about the connecting portion. Normally, a one-way valve closes the inside air outlet due to its own weight, and the pressure difference between indoors and outdoors (for example, the negative pressure that occurs when the vehicle is running and acts on the one-way valve) becomes large enough to overcome its own weight. When the other end is swung away from the inside air outlet,
Moreover, it is provided so as to open the inside air exhaust port.

[Problems to be Solved by the Invention] This conventional ventilation system is used by being attached to a vehicle, for example, and when the inside air inside the conductor is contaminated with cigarette smoke or other substances, the ventilation system promptly exhausts the inside air outside. It is hoped that Therefore, by reducing the weight of the one-way valve, the inside air outlet can be opened even when there is a small pressure difference, and the contaminated air inside the vehicle can be efficiently discharged. However, on the other hand, if the weight of the one-way valve is small, the sealing performance when closing the inside air outlet will be poor, and it will be difficult to close the inside air outlet reliably due to the influence of vibrations when the vehicle is running. . Therefore, contaminated outdoor air (external air containing fine sand, dust, dirt, smoke, etc.) may flow back through the gap between the one-way valve and the internal air outlet and enter the vehicle interior.

At least a portion of the one-way valve that contacts the peripheral edge of the inside air outlet is made of a rubber magnet. Therefore, the one-way valve is attracted to the peripheral edge of the inside air outlet by its magnetic force, and can reliably keep the inside air outlet in a closed state. The one-way valve is, for example, plate-shaped, and one end thereof is connected to a wall surface forming the inside air outlet of the duct, and the other end is swingable around the connecting portion. The one-way valve is provided so that it is swung in the opening direction due to the pressure difference and swung in the closing direction due to its own weight.
