Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to the structure of an air conditioner and an air conditioning duct for a vehicle air conditioner.

0002

[Conventional technology]

Conventionally, vehicle air conditioners have been installed in passenger compartments at both ends of a vehicle 20, as shown in FIGS. 4 to 6. One air conditioner 21, 21 is installed at the top, and each air conditioner 21 is located on the left and right sides of the center of the vehicle body. A connecting duct provided with air outlets 23, 23 equipped with a fan 22 and arranged in the width direction of the vehicle body. A continuous line extending from the end of the vehicle body to the center of the vehicle body is installed on both sides of each air conditioner 21 via the Air is blown to air conditioning ducts 25, 25 arranged in the hand direction.

0003

[Problem that the idea aims to solve]

However, in the above-mentioned structure, there is a connection duct extending from the air outlet 23 of the air conditioner 21 in the width direction of the vehicle body. Since air is blown to the air conditioning ducts 25, 25 through 24, the duct structure becomes complicated. In addition, in order to keep the wind speed below the allowable value and ensure the specified air volume, the cross-sectional area of the duct must be It had to be made somewhat larger, so the ceiling of the cabin was made narrower.

0004 Furthermore, the air must be blown to the end of the air conditioning duct 25 at a predetermined air volume and speed. Therefore, the fan 22 has a large diameter, and the air conditioner 21 has also become large and thick. As a result, the air conditioner occupies a larger proportion of the ceiling, and the ceiling becomes lower. However, in the case of small subway vehicles with small cross-sections aimed at reducing costs, livability is low. It was down.

[0005] Therefore, the present invention aims to reduce the size of the fan by appropriately arranging the air outlet. We have made air conditioners thinner and simplified the structure of air conditioning ducts to reduce air duct loss. By reducing the size of the air conditioning duct, the cross-sectional area of the air conditioning duct can be reduced, thereby raising the ceiling. The aim is to provide a vehicle air conditioning system that can improve livability. Ru.

[0006]

[Means to solve the problem]

In order to achieve the above objectives, the vehicle air conditioner of the present invention is installed in the upper part of the passenger compartment of the vehicle. At the same time, air conditioning ducts were installed in the longitudinal direction of the car body on both sides of the air conditioner. In the first device of the vehicle air conditioner, there are installed air conditioners on both sides of the air conditioner in the vehicle width direction. Each air outlet is provided with an air outlet, and each air outlet is directly connected to the air conditioning duct. However, in the second invention, a plurality of air outlets are provided on each side of the air conditioner in the width direction of the vehicle body. The air conditioning duct is divided into each outlet and connected directly to the outlet. It is a sign.

[0007]

[Effect]

This allows air to be blown directly from the air conditioner's outlet to the air conditioning duct. The duct structure is simplified and air duct loss can be reduced, allowing for disconnection of air conditioning ducts. The area can be reduced.

[0008] In addition, in the second idea, the air conditioning duct connected to each outlet was shortened. As a result, the specified air volume and speed can be secured even with a small amount of air blown out. , the size of the air conditioner can be reduced by making the fan smaller in diameter than before.

[0009]

【Example】

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

0010 A vehicle air conditioner 1 of the present invention includes two air conditioners installed in the upper part of the cabin ceiling of a vehicle 2. It consists of air conditioners 3, 3 and four air conditioning ducts 4 installed on both sides of each air conditioner 3. There is.

[0011] The air conditioner 3 is disposed at a position approximately 1/4 from the end of the vehicle 2 in the vehicle width direction. Two air outlets 5 are provided on each side of both sides, and a fan 6 is installed in each air outlet 5. Each is equipped with one.

0012 The air conditioning duct 4 is divided into four pieces on each side of the vehicle 2 in the longitudinal direction. and are each directly connected to the air outlet 5.

[0013] With this configuration, as shown in FIG. 1, each outlet of the air conditioner 3 5 directly to each air conditioning duct 4, the structure of the air conditioning duct 4 is simplified. This reduces air duct loss.

[0014] In addition, by shortening the length of the air conditioning duct 4 connected to each outlet 5, It is possible to reduce the amount of air flow per the air outlet 5 at several locations, and prevent the air conditioning duct 4 from breaking. The area can be reduced to approximately 1/2 of the conventional area. Furthermore, the air conditioning duct 4 By shortening the length, even if the diameter of the fan 6 is reduced, it will not reach the end of the air conditioning duct 4. A predetermined air volume and speed can be secured, the air conditioner 3 can be made smaller and thinner, and the ceiling can be raised. This can improve the livability of the guest room.

[0015] In addition, if the length of the vehicle is short or if three or more air conditioners are installed, one One outlet is provided on each side of the air conditioner in the width direction of the vehicle body, and the air conditioner is directly connected to each outlet. A similar effect can be obtained by connecting an air conditioning duct.

[0016]

[Effect of the idea]

As described above, in the first invention, the air conditioner is installed on both sides of the vehicle body in the width direction. Since the air outlet is provided directly to the air conditioning duct, the duct structure is The cross-sectional area of the air conditioning duct can be made smaller than before because it is simplified and duct loss is reduced. can also be made smaller.

[0017] In addition, in the second idea, multiple air outlets are installed on each side of the air conditioner in the width direction of the vehicle body. Since air is blown directly from the air outlet to the air conditioning duct that is divided into each air outlet, , the length of the air conditioning duct connected to one outlet can be shortened, and the air conditioning duct can be disconnected. The area can be made smaller than before, and even with a small amount of airflow, the specified air volume and airflow can be achieved. Therefore, the size of the air conditioner can be reduced by making the fan smaller in diameter than before. This allows the air conditioner to be made thinner, and together with the reduction in the cross-sectional area of the duct, the ceiling can be By increasing the height, the comfort of the vehicle can be improved.
