Description

[Detailed Description of the Invention] The present invention relates to an air control device for an automobile, and is an improvement that allows all air intake ports to be closed all at once.

Generally, an automobile has three independent air intakes leading to left and right side ventilators and a heater fan. Each of these air intake ports is provided with an opening/closing control means, and the air intake ports are individually opened and closed. For this reason, each air intake port cannot be closed at the same time.

Therefore, in the past, when following a truck and receiving exhaust gas, entering a dusty road, or entering a foul-smelling area, it took time to close all the air intakes, and dust and foul odors would enter the vehicle. In particular, it was difficult and dangerous to close the left side ventilator, which was far from the driver's seat (assuming a right-hand drive vehicle), while driving.

SUMMARY OF THE INVENTION In view of the above-mentioned prior art, an object of the present invention is to provide an air control device that can close all air intake ports all at once. The configuration of the present invention that achieves this purpose includes on-off valves provided in three independent air intake ports leading to the left and right side ventilators and heater fans, and three on-off control means for individually controlling the opening and closing of each on-off valve. It is characterized by having a master opening/closing control means that closes all the opening/closing valves all at once in priority to the opening/closing control of these opening/closing control means.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is an explanatory diagram conceptually showing a first embodiment of the present invention. As shown in the figure, there are three air intakes 1, 2, and 3 at the front of the car. Air intake 1 is for the left side ventilator, air intake 2 is for the heater fan, and air intake 3 is for the right side ventilator. Leads to side ventilator. Each air intake 1,
2 and 3 are equipped with on-off valves 4, 5, and 6, and these on-off valves 4, 5, and 6 are controlled to open and close by levers 10, 11, and 12 via wires 7, 8, and 9, respectively. Further, each on-off valve 4, 5, 6 is connected to a master lever 16 via master wires 13, 14, 15. In FIG. 1, the open state is shown by a solid line, and the closed state is shown by a dotted line.

In such an embodiment, when the master lever 16 is in the open state (indicated by a solid line), the master wire 1
3, 14, and 15 are loosened. Therefore each lever 1
By opening and closing valves 0, 11 and 12, the opening and closing valves 4, 5 and 6 are opened and closed individually. On the other hand, when the master lever 16 is closed (indicated by the dotted line), the master wires 13, 14, and 15 are pulled, and the on-off valves 4, 5, and 6 are closed all at once. At this time, lever 1
Even if you move 0, 11, 12, the on/off valves 4, 5,
6 will never open. In other words, the closing control by the master lever 16 has priority over the opening and closing control by the levers 10, 11, and 12. Furthermore, when the master lever 16 is returned to the open state, each lever 10,1
The opening/closing valves 4, 5, and 6 are individually controlled by the operations of the valves 1 and 12. Thus, the master lever 16
This allows the on-off valves 4, 5, and 6 to be closed all at once, thereby instantly stopping the inflow of outside air.

FIG. 2 is a circuit diagram conceptually showing a second embodiment of the present invention. In the figure, SW ₁ , SW ₂ , and SW ₃ are switches, and these switches operate electronic control mechanisms 20 , 21 , and 22 . The electronic control mechanisms 20, 21, 22 each include a relay 20a,
21a, 22a, solenoid switch 20b, 2
1b, 22b and vacuum switches 20c, 21c,
22c. On the other hand, SW is a master switch. Then, when the master switch SW is opened and the switches SW ₁ , SW ₂ , and SW ₃ are closed, the electronic control mechanisms 20 , 21 , and 22 are activated, and the on-off valves 4 , 5 , and 6 are closed. On the other hand, switch SW ₁ ,
When SW ₂ and SW ₃ are opened, the on-off valves 4, 5, and 6 are opened. Next, when the master switch SW is closed, the electronic control mechanisms 20, 21, and 22 operate regardless of whether the switches _SW1 , _SW2 , and _SW3 are opened or closed, and the on-off valves 4, 5, and 6 are closed all at once.

As specifically explained above in conjunction with the embodiments, according to the present invention, the air intake ports can be closed all at once since the present invention includes a master control means that closes all the on-off valves all at once.
