【Example】

 Hereinafter, details of embodiments of the present invention will be described with reference to the accompanying drawings. First, FIG. 3 shows an exploded perspective view of an automobile air supply / exhaust ventilation fan device according to an embodiment of the present invention. In FIG. For a circular through hole 11 formed in the wall surface 10 formed, a ventilation fan case that is a housing 20 that is mounted in the vehicle interior of the automobile, and a waterproof cover 30 that is attached from the outside of the automobile are configured.

As will be described in detail later, the housing 20, which is the ventilation fan case, has a fan 21 (a part of which can be seen in FIG. 3) for forming a so-called ventilation fan and a fan for rotating the fan 21. An electric motor is built in, and a duct 22 which is a cylindrical air supply / exhaust pipe projects from the upper surface of the electric motor. A convex screw is formed on the outer peripheral surface of the duct 22, which is the air supply / exhaust pipe. In addition, a slit 23 is formed near the upper surface of the housing 20 which is the ventilation fan case, and a so-called plate-like lid 25 is inserted into the slit 23, and a direction shown by an arrow in the drawing is shown. It is possible to slide to. That is, by sliding the plate-shaped lid 25, the duct 22 which is the cylindrical supply / exhaust pipe can be opened and closed.

On the other hand, the waterproof cover 30 attached from the outside of the automobile includes an outer duct 31 attached to the outer periphery of the duct 22 protruding from the housing 20 as shown in the figure. Although not shown, the inner peripheral surface is formed with a concave screw that is screwed into the convex screw formed on the outer peripheral surface of the duct 22. A flange 32 is provided in the middle of the outer duct 31 so that the rubber packing 33 is sandwiched between the outer wall 31 and the ceiling wall surface 10 of the automobile.

Next, FIG. 1 attached herewith shows a cross section of the above-described automobile air supply / exhaust ventilation fan device. As is clear from the drawing, the upper end portion of the outer duct 31 has A waterproof cover 30 having a substantially disk-shaped outer shape, which is formed so as to cover the entire opening of the outer duct 31, is attached via a plurality of pillars 34, 34. A view of the waterproof cover 30 seen from the AA cross section of the drawing is shown in the attached FIG. In addition, a so-called baffle plate 35 is formed at the upper end portion of the outer duct 31 so as to project in the outer diameter direction. This allows rainwater to pass from the outside through the outer duct 31 into the passenger compartment. It doesn't get in. In addition, reference numeral 36 in the figure denotes a sponge attached to the interior wall surface side of the housing 20.

Next, a method of assembling the above-mentioned automobile air supply / exhaust ventilation fan device will be described. First, for example, a circular through hole 11 is formed in a wall surface 10 forming a ceiling of a vehicle compartment of an automobile, and the formed circular through hole 11 is formed. A housing 20, which is a ventilation fan case, is arranged inside the hole 11 (inside the passenger compartment of the automobile). On the other hand, from the outside (outside the vehicle), the waterproof cover 30 having the packing 33 attached to the outer duct 31 is screwed into the concave screw formed on the inner peripheral surface of the convex screw on the outer periphery of the duct 22 protruding from the housing 20. Then, while rotating one of them, the duct 22 of the housing 20, which is a ventilation fan case, and the outer duct 31 extending downward from the waterproof cover 30 are integrally attached. As a result, this air supply / exhaust ventilation fan device for automobiles can be easily and detachably attached. At this time, the circular through hole 11 formed in the wall surface 10 of the vehicle compartment ceiling is sealed by the rubber packing 33 inserted between the outer duct 31 and the flange portion 32.

FIG. 4 attached herewith shows a state in which the supply / exhaust ventilation fan device for an automobile of the present invention is attached to the wall surface 10 forming the ceiling of the interior of the automobile as described above. In this figure, FIG. 4 (a) is a view of the wall surface 10 of the vehicle compartment ceiling from above the exterior of the automobile, while FIG. 4 (b) shows the wall surface 10 of the ceiling from the vehicle interior of the vehicle. It is the figure seen.

Next, the inside of the housing 20, which is the ventilation fan case, will be described. Inside this, as shown by the broken line in FIG. 1, the fan 21 for forming the ventilation fan and the fan 21 for forming the fan are provided. An electric motor 26 for rotationally driving is built in, and a control circuit 27 for controlling the electric motor 26 is further arranged. Then, a DC power supply (DC DC12V) is supplied to the control circuit 27 from, for example, a vehicle battery 40, and the control circuit 27 rotationally drives the electric motor 26 with the DC power supply. Alternatively, the electric motor 26 may be driven by a power source such as a dry cell instead of the battery 40 of the automobile.

Regarding the control operation of the above-mentioned automobile air supply / exhaust ventilation fan device, for example, a switch 50 as shown in the figure may be provided inside the vehicle, and may be manually switched on / off. Alternatively, it is also possible to detect the vehicle interior temperature by the temperature thermostat 60 arranged in the vehicle interior and automatically control according to the vehicle interior temperature. Furthermore, it is possible to use both of them together. Then, when the control operation is turned on by the control circuit 27, the electric motor 26 rotates to drive the fan 21 to rotate. As a result, for example, as shown by the arrow in the figure, the air in the vehicle compartment is discharged to the outside. It should be noted that a changeover switch (not shown) inverts the polarity of the DC power source applied to the electric motor 26 so that the rotation direction is opposite to that of the air in the vehicle interior. On the contrary, it is naturally possible to introduce outside air into the vehicle compartment. In addition, it is possible to turn on for a set time by using a timer. Further, in addition to the method of reversing the polarity of the DC power source applied to the electric motor 26 to perform normal rotation / reverse rotation, there are naturally other methods.

FIG. 5 attached herewith shows an example of another control circuit of the above-described automobile air supply / exhaust ventilation fan device. In this embodiment, the positive electrode of the battery B (DC12V) is connected to the fuse F, the negative electrode thereof is connected to the vehicle body ground, and the timer TM is inserted and connected between them. Further, the circuit is branched from the fuse F into three, one of which is connected to the rotary switch SW via the engine key COS, the second circuit is connected to the thermo 23R via the rotary switch RS, and the third circuit is connected to the above. It is connected to the timer switch TSW via the rotary switch SW, and then connected again to the electric motor 26 for driving the fan 21 via the supply / discharge switching switch SW. The rotary switch RS can be switched between "manual", "stop", "thermo", and "timer". The supply / discharge switching switch SW reverses the polarity of the DC power source applied to the electric motor 26 to perform normal / reverse rotation.

Further, the above-mentioned automobile air supply / exhaust ventilation fan device is not only used for ventilation during smoking in the passenger compartment and for ventilation in the winter, but also for high temperatures in the passenger compartment when parked in the hot summer in the summer. For example, it is possible to lower the temperature in the passenger compartment by automatically ventilating it with the temperature thermostat described above, and it is also possible to replace fresh air. In addition, in the above-described embodiment, only the example in which the vehicle air supply / exhaust ventilation fan device according to the present invention is attached to the ceiling of the compartment of the vehicle has been described, however, the present invention is not limited to this, and other It goes without saying that, for example, a through hole is formed in the floor wall surface of the vehicle compartment of the automobile or the side wall surface of the vehicle compartment, and the through hole can be attached thereto. Further, it is possible to install the above-mentioned automobile air supply / exhaust ventilation fan device for exclusive use of exhaust gas, and to use the exhaust fan device for exclusive use of exhaust air and the exhaust fan device for exclusive use of intake air separately, that is, by installing two exchange fan devices. It is also possible.
