FIG. 7 shows another example of the ventilation device 3. The air intake of the ventilation hose 4 of the ventilation device 3 in which one end is connected to the distributor 2 attached to the engine 1 is the vehicle of the automobile 7. It is opened in the chamber 8. Then, the air in the passenger compartment 8 is circulated in the distributor 2 for ventilation.

[0006]

[Problems to be solved by the device]

 Among the conventional ventilation systems mentioned above, the one with the air intake side of the hose opened to the inside of the engine room or the one attached to the body member and opened toward the outside of the vehicle has the temperature inside the distributor when the humidity in the engine room and outside air rises. There was a problem in that the water could rise up and condense to cause water droplets to reach the inner wall of the distributor, or the water vapor itself could travel through the hose and enter the distributor, resulting in poor contact.

Further, when the other end of the hose is opened in the vehicle compartment, the ignition noise of the distributor and various mechanical noises (for example, a clicking noise) are transmitted through the hose into the interior of the vehicle and stayed inside. There was a problem with. Therefore, in order to solve these problems, there is a ventilator in which the end of the hose on the air intake side is opened toward the bottom of the ventilation (Japanese Utility Model Publication No. 58-52382). Even when smelled, there is a risk that water during car wash will turn into steam and enter the hose.

The present invention has been made in view of this point, and the air intake side of the hose that ventilates the inside of the distributor is opened in a room that is isolated from the vehicle compartment to allow condensation and water vapor to enter the distributor. It is an object of the present invention to provide a ventilator for a vehicle distributor that prevents mechanical noise from entering the vehicle.

[0009]

[Means for Solving the Problems]

 As a means for solving the above problems, the present invention provides a ventilation air intake to a distributor that performs power distribution work of an engine, and connects one end of a hose that takes in air from the outside to the ventilation air intake. The other end of the hose is opened inside a heater room which is isolated from the vehicle compartment.

[0010]

[Advantage] According to the present invention, the other end of the ventilation hose connected to the distributor, that is, the air inlet is opened inside the heater room which is cut off from the vehicle compartment, so that water content during washing can be reduced. Will not enter the hose as water vapor, and even if the humidity in the engine room or the outside air rises, water droplets will condense on the inner wall of the distributor, and the water vapor itself will travel down the hose and the distributor will It doesn't get inside. In addition, mechanical noise does not get inside the room by being transmitted through the ventilation hose.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 3, wherein the same members as those in FIGS. In the figure, 1 is an engine mounted on the van type vehicle 9 shown in FIG. 4, and 2 is a distributor 2 mounted on the engine 1. A case 10 (see FIG. 3) of the distributor 2 is formed with a ventilation air intake portion 11, and one end of a ventilation hose 4 of the ventilation device 3 is connected to the ventilation air intake portion 11.

Further, the air intake of the ventilation hose 4 is connected to a pipe 16 attached by a grommet 15 to a wall portion 14 of the heater room 13 which is isolated from the vehicle compartment 12 (see FIG. 4). The tip of the pipe 16 is open inside the heater room 13. In this case, it goes without saying that the ventilation hose 4 may be directly connected to the wall portion 14 of the heater room 13. Reference numeral 17 is a lid of the heater room 13, and 18 is a battery box provided outside the vehicle in the lower portion of the vehicle compartment 12. Further, the reference numeral 19 in FIG. 3 is a cap of the distributor 2. The cap 19 of the distributor 2 is provided with a ventilation air discharge portion 20. Since the air outlet provided in the outlet 20 is open toward the end surface of the cap 19, water droplets or the like from the outside do not enter.

When the ventilation hose 4 is attached to the distributor 2 in this manner, when the vehicle 9 runs, the air in the heater room 13 flows into the distributor 2 through the ventilation hose 4 to ventilate the inside of the distributor 2. .. Then, the air inside the distributor 2 is discharged to the outside through the discharge port provided in the cap 19 of the distributor 2 (see FIG. 3). The description of the forced air intake means in this case is omitted. In FIG. 1, reference numeral 21 indicates a vehicle door.

Next, the operation of this embodiment will be described. That is, since the air intake of the ventilation hose 4 connected to the distributor 2 is opened inside the heater room 13 which is cut off from the vehicle compartment 12, the water content at the time of car washing becomes water vapor and the ventilation hose 4 is discharged. There is no need to go inside. Also, even if the humidity of the engine room or the outside air rises, water droplets may condense and reach the inner wall of the distributor 2, or the steam itself may travel through the ventilation hose 4 and enter the distributor 2. The mechanical noise is not transmitted to the passenger compartment 12 through the ventilation hose 4 and is heard by passengers.

[0015]

[Effect of the device]

 As described above, according to the present invention, the air intake of the ventilation hose connected to the distributor is opened inside the heater room which is isolated from the vehicle compartment. If the engine room or outside air gets humid, water droplets may condense and reach the inner wall of the distributor, or the water vapor itself may enter the distributor through the ventilation hose. You won't get lost. This makes it possible to eliminate contact failures inside the distributor. In addition, mechanical noise is transmitted through the hose and does not stay inside the room, improving comfort.
