Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an automatic air adjustment device installed on the roof of a vehicle, and in particular to a device that can be used as an air purifier and ventilation device in a vehicle. .

[Technical background of the invention]

BACKGROUND ART Large vehicles such as buses have heretofore been known to be provided with ventilation devices that can be opened and closed on their roofs. This type of ventilation system uses the wind pressure when the vehicle is running to provide ventilation, so when the vehicle is stopped, the wind pressure disappears and the ventilation function is not achieved. In particular, these days roads are congested and people often stop for long periods of time or drive at very low speeds, and in these cases, a simple natural circulation ventilation system may not have sufficient ventilation capacity, causing the temperature inside the vehicle to rise. Moreover, the air is also polluted, causing significant discomfort to passengers.

Additionally, although this type of natural circulation ventilation system is effective when drawing outside air directly into the room, such as in the summer, it is not recommended for use when the outside temperature is uncomfortably low, such as in the winter. It is impossible. and,
In such a case, when the air becomes polluted due to smoking, etc., no effective function can be performed to prevent the air from becoming polluted. This also applies in the summer when the room is air-conditioned and it is not desirable to bring outside air into the room.

As described above, conventional ventilation systems have the disadvantage that they do not perform adequately when the vehicle is stopped, and that they do not purify the air at all when it is not desirable to introduce outside air into the room.

[Purpose of invention]

The present invention was developed in view of the problems of the prior art as described above, and its purpose is to allow outside air to circulate indoors not only when driving but also when stopped, and even when no ventilation is performed. An object of the present invention is to provide an automatic air adjustment device for a vehicle that can purify air.

[Summary of the idea]

The automatic air adjustment device for vehicles of the present invention is installed in an opening provided in the roof of a vehicle, and consists of a top lid that opens and closes the opening, a wind direction control plate that interlocks with the top lid, and a motor that drives the device. It consists of an air circulation fan and an air purifying pack made of activated carbon, electrodes, etc. When the top lid is opened, the fan and wind direction control plate direct outside air into the room without passing through the air purifying pack. Ventilate by incorporating
On the other hand, when the top lid is closed, the air inside the room is guided to the air cleaning pack by the wind direction control plate, and the air is cleaned.

A wind direction control plate 14 is rotatably attached to the center of the main body case 5 via a support shaft 13. This control plate 14 is biased so that its front part rotates upward by a torsion spring (not shown) provided between it and the support shaft 13. In particular, as long as no force is applied to this control plate 14, , the air cleaning side inlet 9 and the ventilation side inlet 10 at the front of the main body case are shielded so that they do not communicate with each other. Airtight members 15 made of an elastic member such as rubber are attached to both front and rear ends of the control plate 14 in order to ensure airtightness of the contact area between the inner surface of the main body case 5 and the control plate 14.

An upper lid 16 is provided on the roof of the vehicle so as to cover the opening 1 from above. This upper lid 16 is rotatably attached to a support shaft 17 provided in the front of the frame 2, and when the upper lid 16 is raised, an indoor air outlet 18 is formed between the rear of the upper lid and the rear of the frame 2. It is something that will be done. Further, a torsion spring 17a is provided at the portion of this support shaft 17, and this torsion spring 17a causes the upper lid 16 to
is always biased in the closing direction. This upper lid 16
is opened and closed in conjunction with the lifting and lowering of the main body case 5, and has an opening 1 on the front inner surface of the upper lid 16.
An upper lid operating arm 19 is fixed that penetrates through and reaches the bottom surface of the main body case 5. The lower end of this operating arm 19 is a fixing rod 20 extending in the width direction on the bottom surface of the main body case 5, and this fixing rod 20 connects to a guide portion 21 which is a gap formed below the air purifying pack 12. It is slidably engaged inside. The guide portion 21 also includes an upper lid 16.
A locking mechanism (not shown) is provided for locking the fixing rod 20 when it reaches the open position.

A partition plate 22 is provided on the lower surface of the upper lid 16 and bent into an L-shaped cross section from the center to the rear. As shown in FIG. 4, this partition plate 22 is composed of a planar spiral side plate 22a that is open at the rear side of the upper lid 16, and a bottom plate 22b that closes the bottom of the side plate 22a and serves as a partition from the main case 5. . The bottom plate 22b of the partition plate 22 has a size that closes the upper opening of the main body case 5, and a motor 23 is fixed to the center thereof. A fan 24 connected to the output shaft of the motor 23 is arranged in a space on the upper lid 16 side of the partition plate 22. A ventilation hole 25 is provided in a portion of the bottom plate 22b that faces the fan 24. Furthermore, an airtight material 26 is provided at the rear end of the partition plate 22 to close the gap between the partition plate 22 and the bottom of the main case 5 when the top cover is closed.

is fixed, and this operating metal fitting 27 is in contact with the surface of the wind direction control plate 14.

A solar cell 28 serving as a power source for the motor 23 is provided on the external surface of the top cover 16 having such a structure, and the solar cell 28 and the motor 23 are electrically connected to a drive switch mechanism (not shown). .

(2) Operation Next, the operation of this embodiment having the above configuration will be explained.

During air purification...Fig. 2 When the main body case 5 is not pushed up, the fixing rod 20 does not slide inside the guide part 21 and the operating arm 19 is in a vertical position, and the main body case is attached via this arm 19. The upper lid 16 that interlocks with the upper lid 16 is urged downward by the force of a torsion spring 17a provided on the support shaft 17, and is in close contact with the upper edge of the frame 2, so that the opening 1 is closed. At this time, the motor 23 fixed to the partition plate 22 of the upper lid 16 is also in the lowered position, and the operating metal fitting 27 at the bottom of the motor 23 is pressing the wind direction control plate 14. Therefore, the front part of the wind direction control plate 14 is in close contact with the bottom surface of the main body case 5, and the rear end is in close contact with the lower surface of the bottom plate 22b of the partition plate 22, so that the air purifying side intake of the main body case 5 is prevented. The opening 9 communicates with a ventilation hole 25 provided on the bottom plate of the partition plate 22. Further, since the rear end of the bottom plate 22b of the partition plate 22 comes into contact with the rear part of the bottom plate of the main body case 5, the fan 2
4 and the ventilation side inlet 10 at the rear of the main body case.

In this state, when the control switch is turned on and the motor is driven, the fan 24 rotates and indoor air is sucked in through the suction port 9 and passes through the air cleaning pack provided here. At this time, contaminants such as cigarette smoke and dust in the air are absorbed by the action of the high-voltage electrode plates and activated carbon inside the pack. The thus purified air passes through the ventilation hole 25 provided in the partition plate 22 by the rotation of the fan 24, moves to the lower surface of the top cover 16, and then passes through the duct formed by the top cover 16 and the wind direction control plate 14 to the main body. Ventilation side intake port 10 at the rear of case 5
It is then discharged back into the vehicle. By repeating such circulation, the air in the room is purified, and this device performs the same function as a normal air purifier.

During ventilation...Figure 3 To circulate outside air into the room while the vehicle is running or stopped, do the following. That is, when the front part of the main body case 5 is lifted upward using the handle 8, the fixing rod 20 slides backward within the guide part 21, and at the same time, the upper cover 1 is moved through the operating arm 19.
6 is lifted and its rear part becomes open. When the top cover 16 is raised, the motor 23
And since the operating fitting 27 rises, the wind direction control plate 14, which has been held down by this operating fitting 27,
The support shaft 13 is rotated clockwise in the figure by the force of a torsion spring provided on the support shaft 13. The front end of the wind direction control plate 14 is in contact with the bottom of the partition plate 22, and the rear end is in contact with the bottom of the main body case 5. A space between the plate 22 and the ventilation hole 25 provided in the bottom plate 22b is shielded by the control plate 14. At the same time, the top lid 1 was opened.
The partition plate 22 fixed to the main body case 5 rises, and the rear end of the bottom plate 22b comes into contact with the rear upper edge of the main body case 5. As a result, the rear end of the top lid 16 and the partition plate 2
2 air outlet 18 on the top surface, ventilation hole 25 at the bottom of the partition plate 22, and ventilation side inlet 1 at the rear of the main case 5
0 is in a continuous state.

When the motor 23 is driven and the fan 24 rotates in this state, indoor air is sucked into the case from the ventilation side intake port 10 and passes through the ventilation hole 25 provided in the partition plate 22 and the exhaust port 18 at the rear of the top cover 16. It is then discharged to the outside. In this case, there is no need for air purification and the life of the cleaning pack 12 is extended, so that the exhaust air from the room is removed from the cleaning pack 12.
In order to prevent the air from passing through, the air intake port is changed from the air purification side intake port 19 to the ventilation side intake port 10.

By the way, in order to drive the motor that performs ventilation as described above, it is common to use a battery mounted on the vehicle, but considering the battery consumption during parking, the motor as in this example By using the solar cell 28 as a driving power source, a more efficient automatic air adjustment device can be expected. In other words, the current capacity of solar cells is
Since it is around 0.1W/cm ² , and 3W or around 3W is desirable for a fan drive motor, the area of the solar cell is 30cm ² or more. When using such a 3W motor, the amount of air ventilation is about 30m ³ /(hour), so the temperature rise inside a general passenger car can be kept within a range that is not much different from the outside temperature. becomes possible. As a result, in the past, when parking in the summer, the closed interior of the vehicle would become extremely hot, causing discomfort when starting the vehicle, and a cooler would be required to have a large initial capacity to bring the interior temperature down to an appropriate temperature. However, according to this embodiment, it is possible to suppress the rise in indoor temperature while parking, so it is possible to improve the initial capacity of the cooler, achieve miniaturization, and reduce the temperature during cool-down. There is an advantage that it is possible to eliminate the discomfort of

Furthermore, by connecting the solar cell to the on-vehicle battery with simple wiring, it can be used to charge the battery during times when ventilation is not required, such as in winter, protecting the battery and reducing the inefficient charging time compared to the engine. It can be significantly shortened and energy consumption can be prevented.

Note that the present invention is not limited to the illustrated embodiment, and instead of a solar cell, a battery mounted on a vehicle may be used as it is as a drive source for the motor. In addition, in the illustrated embodiment, the main case is attached to the roof so that it can be raised and lowered as a means for opening and closing the top cover, and the main case and the top cover are interlocked, but the main case is fixed to the roof and a It is also possible to open and close the top lid by protruding the operating arm directly into the room and operating this arm. In addition, in the illustrated embodiment, a partition plate 22 is provided on the top lid.
is provided to support the motor 23 and fan 24, but these motors and fans may be directly fixed to the main body case 5 or attached to the top cover 1.
It can also be fixed to the bottom surface of 6. Further, in the present invention, the partition plate 22 is not necessarily necessary, and it is possible to switch between the air purification side and the ventilation side inlet only by using the upper cover 16 and the wind direction control plate 14 linked thereto. . Furthermore, the means for interlocking the wind direction control plate 14 and the upper lid 16 does not need to be an operating metal fitting provided at the bottom of the motor 23;
6 and the wind direction control plate 14 may be directly linked, or when the main body case moves up and down as shown in the figure,
It is also possible to move the wind direction control plate 14 by raising and lowering the main body case.

[Effect of idea]

As described above, according to the automatic air adjustment device of the present invention, a motor and fan are attached to the top cover that is freely opened and closed on the roof of the vehicle body, and the air circulation path is changed by opening and closing the top cover, which has the advantage that the interior of the vehicle can be ventilated even when the vehicle is stopped, and the air inside the vehicle can be purified even when the top cover is closed.

In particular, the present invention extends the life of the air purifying pack by changing the air circulation path between air purification and ventilation.
Another advantage is that the frequency of replacing or cleaning the pack is low, making maintenance management easy.

Furthermore, if a solar cell as in the illustrated embodiment is used as a drive source for the motor, energy consumption can be saved and batteries can be protected, making it possible to provide a more efficient automatic air conditioning system for vehicles.
