2. Description of the Related Art Conventionally, 2 having a plurality of private chambers and passages
As an air ventilating device for vehicles such as a multi-story sleeper limited express train, for example, as described in Japanese Patent Publication No. 7-98482, air-conditioning air temperature-controlled by an air conditioner unit is passed from a main duct to a branch duct. Although it is known that air is distributed to each private room via the air conditioner, in such a device, since the air conditioning in each private room is prioritized, the current situation is that no consideration is given to air conditioning in the passage. .

Therefore, as an air-conditioning ventilation system for such a vehicle, the inventor not only distributes conditioned air to a private room, but also air-conditions a passage, as shown in FIGS. I thought of something to distribute the wind.

That is, a total of two air conditioner units 101A and 101B, one at each end of the vehicle 100, are arranged, and air conditioning is performed at the front portion and the rear portion of the vehicle 100, respectively. To bear. Air conditioner unit 10
The air-conditioned air CA whose temperature is controlled by 1A and 101B is supplied to each private room S,
The main duct 102 that distributes air to the S / T and each passage R is
From one front duct part 102A communicating with the front air conditioner unit 101A to the central duct part 10 for the upper floor passage
2B, floor upper right private room central duct portion 102C, floor upper left private room central duct portion 102D and lower floor passage central duct portion 102E, lower floor right private room central duct portion 10
2F, the lower left floor private room central duct portion 102G is branched into a total of 6 central duct portions, and these central duct portions 102B to 102G are gathered together to be connected to the air conditioning unit 101B in the rear portion. The rear duct portion 102H is configured.

Branch ducts 103R, 103L, 1 corresponding to the private rooms on the first floor (a total of four rooms, a single room S and a single / twin room S / T) from the front duct portion 102A
04R, 104L is branched, branch duct 103R, 1
Private room S or S ・ T through 03L, 104R, 104L
Is distributed to. Since the front duct portion 102 is located above the passage R, the front duct portion 102A

In the two-story structure, on the upper floor, the branch ducts 105R and 105L are branched from the upper right private room central duct portion 102C and the upper left private room central duct portion 102D, respectively. Air-conditioning air is distributed to each upper private room S. Downstairs,
Similarly, each of the branch ducts 106R and 106L is branched from the central duct portion 102F for the lower-right private room and the central duct portion 102G for the private lower-left room to distribute the conditioned air to the individual private rooms S of the lower floor. . The air is distributed to the upper and lower passages R directly from the upper duct central duct portion 102B and the lower passage central duct portion 102E.

Further, from the rear duct portion 102H, branch ducts 107R, 10 are provided with respect to the first-floor toilet F and Western-style toilet W1 on the right side and the left-side toilet F and Japanese-style toilet W2.

The conditioned air is distributed to T directly from the rear duct portion 102H. EN is the entrance and exit.

The air-conditioned air CA distributed to each private room is
8% of the total air volume from each private room S or S ・ T via the passage R
A certain amount of air conditioning air EX is discharged to the outside of the vehicle, about 8% of fresh air FA is added to the remaining air conditioning air RA of about 92%, the temperature is adjusted by the air conditioner units 101A and 101B, and the main duct 102 and the branch again. Duct 103R, 103
L, 104R, 104L, 105R, 105L, 106
Air is distributed to each private room S or S · T through R, 106L, 107R, 107L.

[0009]

By the way, in general, the adjustment of the blowing amount of the conditioned air in the air-conditioning ventilation device is performed in each private room S.
Alternatively, in the duct structure as described above, when the blown air volume is adjusted for each of the individual chambers S or S / T, each of the branch ducts 103R, 103L, 104R, 10 is performed.
4L, 105R, 105L, 106R, 106L, 10
In 7R and 107L, the tip ends open to the individual chambers, and the base ends communicate with the common duct portions 102A to 102H. Therefore, fluctuations due to the adjustment of the blown air amounts to the individual chambers are the amount of air taken into the branch ducts. And, consequently, the air volume of the common duct portions 102A to 102H is changed, which sensitively affects the air volume of the air blown out from the adjacent private room, which may make it difficult to control the air volume of each private room. Therefore, there is a demand for improvement from the viewpoint of pursuing comfort.

In addition to that, the air conditioner unit 101A,
The air-conditioned air CA whose temperature is controlled by 101B is a total of six central duct portions 102B including two passage central duct portions and four private room central duct portions in the two-story structure portion.
Since the duct structure is such that the air is branched to 102 G and the air is branched from these central duct parts to the respective branch ducts, the duct structure including the branch part and the whole becomes very complicated. Also, it requires an excessive duct space, which makes the design difficult. Furthermore, the number of parts is large, the assembly work is complicated, and the difficulty level is high.

It is an object of the present invention to provide an air conditioning and ventilation system for a vehicle which has a simple duct structure and is capable of adjusting the blown air volume of each individual room without affecting the blown air volume of the adjacent private room. .

[0012]

In a vehicle air-conditioning ventilation system according to the present invention, conditioned air is supplied to a main duct extending in the longitudinal direction of the vehicle, and a branch is made from this main duct corresponding to each private room. This is an air-conditioning ventilation system for vehicles that distributes air to each private room through ducts .

If the amount of air discharged into the passage decreases, and conversely the amount of air taken into the private chamber decreases, the amount of air discharged into the passage increases, and the change in the amount of taken air only changes the amount of air discharged into the passage. It does not change the amount of air taken in. Therefore, it is possible to adjust the air volume to obtain comfort for each individual room without affecting the blown air volume of the other adjacent private room.

Further, since the air is distributed to the passage through the branch duct (stem duct), the air-conditioning air is distributed to the passage portion of the one-story structure and each of the upper and lower passage portions of the two-story structure. It is not necessary to provide a duct part dedicated to the passage to wind, and a simple duct structure with a minimum duct space can be obtained.

[0016]

Further, in the branch duct, the ratio of the air volume of the air conditioning air to the private room and the air volume of the air conditioning air to the passage is freely changed by the air volume adjusting means, and the remainder of the air conditioning air taken into the private room is It will be reasonably released into the passage.

In addition, in the portion of the two-story structure, the main duct has left and right upper floor duct portions arranged above the partition plate, and left and right lower floors arranged below the partition plate.

The present invention is implemented as described above and has the following effects.

In the vehicle air ventilator according to the present invention, a part of the conditioned air distributed from the main duct to the trunk duct is divided into individual rooms through the air conditioning air intake section for each branch duct branched corresponding to each individual room. Since the intake air is taken in and the rest is discharged to the passage, the fluctuation of the intake amount of the conditioned air into the individual room only affects the amount of air discharged into the passage, and affects the blown air volume of other adjacent private rooms. Can be eliminated. Therefore, it is possible to adjust the air volume for each individual room to obtain comfort. In addition, the branch duct is designed to distribute the conditioned air to the passage as well as to the private room, so it is possible to omit the dedicated main duct for distributing the conditioned air to the passage. A simple duct configuration with minimal space can be obtained. As described above, since the duct structure is simple and the air volume in each individual chamber is easily adjusted, the total cost of manufacturing and maintenance can be reduced.

With the structure having the means, the air volume taken into the private room can be freely changed by the air volume adjusting means, and the ratio of the air distribution quantity to the private room and the air distribution quantity to the passage can be easily changed.

When the vehicle has a two-story structure in which a partition plate divides the room into upper and lower floors, and has a passage between the left and right private rooms, the main duct is With a simple duct structure, by having a configuration having left and right upstairs duct portions arranged on the upper side of the partition plate and left and right downstairs duct portions arranged on the lower side of the partition plate, It is possible to divide the left and right private rooms downstairs into four groups so that each group has a main duct, and the air volume is controlled for each group, making it less susceptible to the influence of changes in the air volume of other groups. .

In addition to this, in the case of such a two-story structure, the trunk duct of the branch duct branched from the above-mentioned floor duct portion extends in the vehicle width direction along the partition plate to the vicinity of the passage. It has a horizontal portion that extends and a vertical portion that communicates with the horizontal portion and is bent vertically upward in the vicinity of the passage and has a tip that extends to the vicinity of the ceiling, and the air conditioning air intake portion is provided in the middle of the vertical portion. If this is done, the air-conditioned air that has been air-conditioned will be taken into the private room from a relatively high position through the trunk duct of the branch duct, and the remaining air-conditioned air will be distributed from the vicinity of the ceiling to the aisle, thus providing efficient air conditioning and ventilation on the upper floors. It can be carried out.

The trunk duct of the branch duct branched from the downstairs duct portion extends along the partition plate in the width direction of the vehicle to the vicinity of the passage, and an opening communicating with the passage is formed in the lower part of the private room. If formed, the temperature-controlled conditioned air is taken into the private room from above through the trunk duct of the branch duct, and excess conditioned air of the taken-in conditioned air is discharged to the passage through the lower opening. On the other hand, the remaining air-conditioned air that has been distributed in the private room is distributed directly from the vicinity of the ceiling to the aisle, and efficient air-conditioning ventilation can be performed even in the downstairs.

Further, the main duct communicates with a base-side duct portion, one end of which is connected to the air conditioning unit and extends in the longitudinal direction of the vehicle above the passage, and the other end of the base-side duct portion. The vehicle has a middle duct portion that is wide in the vehicle width direction, and left and right central duct portions that have one end communicating with the left and right end portions of the intermediate duct portion and the other end portion that extends downward. If the left and right upstairs duct portions and downstairs duct portions are communicated with each other, the conditioned air temperature-controlled by the air conditioning unit is passed from the proximal duct portion to the intermediate duct portion to the left and right. It distributes air to the central duct part of, and then distributes it to the left and right upstairs duct parts and downstairs duct parts so that the air volume is gradually reduced without disturbing the flow. It is possible to distribution wind.

When the private room is a single / twin room divided into upper and lower rooms, the trunk duct of the branch duct may be provided with two conditioned air intake portions corresponding to each room. For example, in the upper and lower two chambers, it is possible to take in the conditioned air from the conditioned air intake portions corresponding to the respective chambers so that there is almost no difference between the upper and lower chambers.
