運転を行なわないでいるという危険もある。 Furthermore, one filter is swingably provided,
A ventilation system for an automobile is also known in which a bypass path is formed in the non-operating position of the filter (Japanese Utility Model Publication No. 49-16028). Swinging of the filter is now performed via a switch at the driver's discretion. Since only one filter is provided here, in the inactive position of the filter no purification of the air takes place anymore. A major drawback is that the command to move the filter to the inactive position is given manually and is therefore dependent on the subjective judgment of the operator. In other words, when air is passed through a filter, passengers are breathing purified air, but when the harmful substances in the air have been reduced to a tolerable level.
Since no indication is given to the passenger, there is a risk that the filter will swing into the inactive position too soon or too late. Moreover, since various dangerous air components are not perceived by smell, there is also the risk that the filters will not be in operation.

Furthermore, while the precision filter is in operation, outside air cannot continue to be introduced into the passenger compartment.

ことができる。Effects of the Invention According to the invention, a detector is provided in the outside air intake stream upstream of the precision filter, which is spatially separated from the dust filter, and is connected to a computing device to detect harmful substances in the outside air intake stream. When the value falls below a predetermined value, this calculation device issues a command to the operating device to swing the precision filter to open the air passage opening.
A long lifespan of precision filters can be obtained without reducing the quality of air purification. Further, according to the present invention, the concentration of harmful substances in the inhaled outside air is constantly detected by the detector, and the precision filter is brought to the operating position when the concentration exceeds a predetermined limit value, so that the inhaled outside air is appropriately purified. Moreover, below the limit value, the precision filter is brought into a non-operating position, so that the service life of the precision filter can be increased, while the purification of the intake outside air by the dust filter continues. Furthermore, a precision filter that captures harmful substances is installed in the outside air intake stream, and a detector located further upstream from this precision filter in the outside air intake stream detects the harmful substances in the outside air before they enter the passenger compartment. Outside air can continue to be supplied to the passenger compartment while the precision filter is in operation, without the need for a regular blower.

風機の供給出力を減少することができる。 In the inactive position of the precision filter 10, shown in solid lines, this filter 10 opens the air passage opening 12, so that the air exiting the dust filter 9 bypasses the precision filter 10 and passes through the air passage opening 12 for heating-ventilation and ( or) can enter the next range (not shown) of the air conditioner. precision filter 1
In addition to the protection of 0, a reduction in flow resistance occurs, so
The air flow rate is increased and, if necessary, the supply power of the connected blower can be reduced.

This operating device 15 is operatively connected to a computing device 16, which is associated with a detector 17 located in the air stream. The detector 17 constantly detects the concentration of harmful substances in the incoming air and, at predetermined limit values, the computing device 16 connected to it reacts. If this concentration exceeds a limit value, the actuating device 15 is acted upon by the precision filter 10 to close the air passage opening 12, the precision filter 10 then assuming the position shown in dotted lines.
Below the limit value, the precision filter 10 again moves into the inoperative position shown in solid line.
