Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a ventilator in a car such as a passenger car or a truck. The present invention relates to a ventilating device for preventing the occurrence of an accident.

(Prior art and its problems) The temperature inside the vehicle during parking with the engine stopped is too high to be experienced in daily life. For example, if a car is left under the hot summer sun, the temperature inside the car can reach 60-70 degrees.

If the engine is kept running, the car cooler can prevent the inside of the vehicle from becoming hot, but this is not practical in terms of increased combustion consumption and safety.

It is conceivable that the windows are opened, but this is not practical because there is a risk of theft.

As means for solving these problems, JP-A-59-1141
A ventilator for automobiles of No. 08 and an in-house ventilator for parking at No. 1-1161809 have been proposed.

However, since all of these ventilation systems take in the outside air on the vehicle surface exposed to sunlight into the car, even if they can be aroused, the temperature inside the car has not been sufficiently lowered by ventilation. .

Also, if the inlet of the intake passage is opened below the vehicle body, depending on the mounting position of the valve, running while the road surface is contaminated with rainwater, the rainwater jumped deep inside the passage with tires The leaked sludge adheres to the device, accelerating the corrosion of the device and causing a failure. In particular, in the intake passage, dust generated by drying the attached sludge becomes dust when the apparatus is operated and enters the vehicle.

The idea is to solve such a problem.

(Means for Solving the Problems) The in-vehicle ventilation device of the present invention includes a solar power generation device in which a light collector for receiving sunlight is appropriately disposed on the outer surface of the vehicle, an exhaust passage for guiding the air in the vehicle to the outside of the vehicle, and an external device. An intake passage for introducing air into the vehicle, an exhaust device having an on-off valve for forcibly exhausting the air in the vehicle from the exhaust passage, and an intake device having an on-off valve for forcibly taking in external air into the vehicle, In the above, the exhaust passage opens to the ceiling side inside the vehicle, and is arranged so as to send out the air in the upper layer of the vehicle below the vehicle body through the inside of the vehicle body structure. The intake device and the exhaust device are electrically connected to open and close the on-off valve by the supply of power from the photovoltaic power generation device, respectively. The on-off valve is used as a drive source. A solenoid, a swinging rod pivotally supported at the tip of a plunger of the electromagnetic solenoid, a valve part extending from one end of the swinging rod to close the passage, and a state in which the valve is always closed. And a biasing spring suspended from the other end of the swinging rod so as to keep the biasing force at the inlet end of the intake passage. In this configuration, a plurality of waterproof walls are provided so as to overlap the waterproof walls alternately at intervals.

(Operation) If the photovoltaic power generator installed outside the car and the exhaust and intake devices are electrically connected while the engine is stopped and the car battery is not used, the required power generation can be achieved. While the sun shines on the car, power is supplied to the exhaust and intake systems, and the respective on-off valves are opened. On the other hand, the hot air inside the vehicle is sequentially absorbed from the ceiling side where the hot air that has become hot tends to gather, and is discharged to the lower part of the vehicle body through the internal structure of the vehicle body. The cold air is sequentially pushed up from the floor side to the ceiling side in the vehicle in a layered manner, and the cool air and the warm air are not agitated in the vehicle, and the temperature inside the vehicle is efficiently lowered.

In addition, in the present invention, since the outlet for discharging the warm air to the outside is provided under the vehicle body while the warm air in the car is sucked from the ceiling side, there is no danger of rainwater entering from the outside.

Also, in the present invention, the waterproof walls are provided alternately at intervals in the passage outside the inlet of the intake passage.
Depending on the mounting position of the valve part, it is possible to prevent the sludge painted on the rainwater jumped up by the tire from adhering deep inside the intake passage by traveling when the road surface is dirty with rainwater. it can.

The urging spring 50 is suspended at one end of the swinging rod 47 in a direction in which the plunger 46 is pulled out.

On the other hand, from the other end of the swinging rod 7, a valve portion 51 that shuts off the passage 41 is provided.
In this embodiment, the valve portion 51 and the swinging rod 47 are integrated in an L-shape.

The L-shaped corner portion, that is, the end portion of the swinging rod 47 that contacts the base of the valve portion 51, is pivotally mounted so as to be the center of rotation.

Therefore, when the electromagnetic solenoid 45 is not energized,
The urging spring 50 causes the swinging rod 47 to be in a raised state, and the valve portion 51 closes the air supply passage 41.

Then, when the electromagnetic solenoid 45 is energized, the plunger 46 is sucked against the biasing spring 50, and the swinging rod 47 is pulled down about its pivotal connection, and the valve 51 is moved to the position shown in FIG. Tilt as shown by the dashed line. Thereby, the intake passage 41 is opened.

On the inlet side of the intake passage of the intake device 40, a waterproof wall 52 inclined downward from the inner wall of the passage toward the center of the passage is provided.
Are provided with a plurality of waterproof walls so as to overlap at alternate intervals. By inclining the waterproof wall 52 downward, the wet sludge adhering to the waterproof wall 52 can be shaken off by the running vibration of the car, and the amount of adhesion can be reduced.

Explaining in detail with reference to the drawings, waterproof walls 52A and 52B for preventing rainwater from entering from outside are provided alternately at intervals in the intake passage 41 outside the valve portion 51.
As shown in FIG. 5 (A), the waterproof wall 52A of the embodiment is provided with an appropriate gap on one side of the passage portion 41A where the passage 41 is vertically divided, and has a length exceeding half of the diameter of the passage. It is arranged in a shape.

On the other hand, as shown in FIG. 5 (B), waterproof walls 52B are similarly arranged at appropriate intervals on the side of the other vertically divided passage portion 41B.

By combining the divided passage portion 41A and the passage portion 41B, as shown in FIGS. 3 to 6, the passage 41 has a waterproof inside between the waterproof wall 52A and the waterproof wall 52A. The wall 52B is assembled so as to be inserted.

In the embodiment, the introduction port 32 of one exhaust passage 31 for ventilating the outside of the vehicle and the inside of the vehicle is opened to the ceiling side of the vehicle, so that the warm air collected in the upper layer is preferentially sent out of the vehicle, and the other intake passage 41 is provided. The opening 43 is formed so as to penetrate the floor (floor) 24 of the vehicle body and open to introduce relatively low-temperature air under the vehicle body, which is shaded, into the vehicle.

Therefore, high-temperature air that is warmed in the vehicle and collects on the ceiling side, that is, warm air, is forcibly discharged to the outside of the vehicle from the outlet 33 through the exhaust passage 31 from the inlet 32 on the ceiling side, and the temperature under the vehicle body is relatively low. Cold air is introduced into the vehicle via the intake passage 41.

The above-described inlet 32, the inlet 43, etc. are not limited to the arrangement positions shown in the embodiment, and according to the shape and design of the car, respectively,
The position is not limited to the illustrated mounting position as long as it can take in air in the upper part of the vehicle or low-temperature air under the vehicle body. Needless to say, the exhaust passage 31 and the intake passage 41 may be provided according to the vehicle body structure.

The exhaust device 30 and the intake device 40 are connected to each other using a photovoltaic power generator as an electric drive source.In the power supply circuit, or by providing a power-on switch to the exhaust device 30 or the intake device, In winter, the circuit may be opened to stop the exhaust device 30 and the intake device 40.

When these are stopped, as described above, each passage 31, 41
Is closed by the respective on-off valves 34 and 44, and the inflow of outside air can be prevented.

In this embodiment, a passenger car has been described as an example, but the present invention can be applied to a general vehicle including an internal combustion engine such as a truck.

(Effects of the Invention) According to the present invention, the cool air under the body, which is shaded and has a relatively low temperature, is taken into the vehicle from the floor side in the room, while the hot air in the vehicle is concentrated on the ceiling side where the warmed-up hot air tends to gather. Is absorbed from the vehicle body and is discharged to the lower part of the vehicle body through the internal structure of the vehicle body.Therefore, the cool air under the vehicle body, which is much lower than the general temperature of the outside air, is gradually pushed up from the floor side to the ceiling side in the vehicle. Since the air can be sent in, the temperature inside the vehicle can be reduced efficiently without the cool air and the warm air being stirred inside the vehicle.

Therefore, the ventilation in the vehicle can be performed quickly, and the energy consumption can be minimized.

In addition, in the present invention, since the outlet for discharging the warm air to the outside is provided under the vehicle body, while the warm air in the vehicle is sucked from the ceiling side, rainwater is prevented from entering the vehicle.

In the present invention, the inlet of the intake passage for taking in the cool air is open under the vehicle body. In the passage outside the inlet of the intake passage, waterproof walls are provided alternately at intervals. Therefore, depending on the mounting position of the valve, it is possible to prevent the wet sludge from adhering to the rainwater jumped up by the tire deep inside the intake passage by traveling when the road surface is dirty with rainwater. Thus, it is possible to reduce corrosion of the apparatus due to the adhesion of sludge to a deep passage which is difficult to clean, and a failure accident.

Further, by providing the prevention wall 52 so as to be inclined downward, the wet sludge adhering to the prevention wall 52 can be shaken off by the running vibration of the vehicle, and the amount of adhesion can be reduced.

In particular, by preventing the sludge from adhering to the intake passage, it is possible to reduce the invasion of dry sludge dust into the vehicle during operation of the present apparatus.
