Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、車両用換気装置に係り、特に高速で走行す
る車両に好適な車両用換気装置に関するものである。Description: TECHNICAL FIELD The present invention relates to a vehicle ventilator, and more particularly to a vehicle ventilator suitable for a vehicle traveling at high speed.
従来、高速でトンネル内を走行する車両にあっては、
特に対向車両とすれ違う場合、車外圧力が急激に変化す
るため、該圧力変動が車内にまで伝播し乗客に不快感を
与える問題が生じていた。そこで、前記車外圧力の変動
に対して風量の変動が少ない送風機を給気装置と排気装
置に用いて乗客に与える影響を最小限に抑える換気装置
が知られている。Conventionally, in a vehicle that travels in a tunnel at high speed,
In particular, when passing an oncoming vehicle, the pressure outside the vehicle changes abruptly, and the pressure fluctuation propagates into the inside of the vehicle, causing a problem that passengers feel uncomfortable. Therefore, there is known a ventilation device in which an air blower, which has a small change in air volume with respect to a change in outside pressure, is used as an air supply device and an exhaust device to minimize the effect on passengers.
なお、この種の装置として関連するものには、例えば
特公昭58−9022号等が挙げられる。Note that, as a device related to this type, for example, Japanese Patent Publication No. 58-9022 is cited.

却されるため、排気の昇圧による熱のために冷却効率が
低下する恐れがあった。In the above-mentioned prior art, sufficient consideration has not been given to efficient cooling of the drive motors for the air supply device and the exhaust device. That is, the drive motor of the air supply device is cooled by the supply air taken into the vehicle by the air supply fan, and the heat of the motor becomes a heat load when cooling the vehicle interior. On the other hand, the drive motor of the exhaust device is cooled by the exhaust fan exhausted to the outside of the vehicle, but is cooled on the downstream side by the exhaust fan in the air flow path of the exhaust gas, so it is heated by the pressure rise of the exhaust gas. There was a risk that the cooling efficiency would decrease.
また、前記給気装置および排気装置においては、各フ
ァンの騒音が直接車内に伝播し易い構造となっており、
各ファンと車内開口部との間に消音器等を設ける必要が
あり、構造が複雑なものとなる恐れがあった。Further, in the air supply device and the exhaust device, the noise of each fan has a structure that easily propagates directly into the vehicle,
It is necessary to provide a silencer or the like between each fan and the opening in the vehicle, which may complicate the structure.
本発明の目的は、ファンを駆動するモータを効率的に
冷却すると共に、低騒音の車両用換気装置を提供するこ
とにある。It is an object of the present invention to efficiently cool a motor that drives a fan and to provide a low-noise vehicle ventilation device.
上記目的は、 一つのモータの軸の一端に給気ファン、他端に排気フ

気口に接続する排気ダクトとを接続しており、 前記半径方向の他端側の前記ケースと前記排気ファン
に接続する第２の排気ダクトとを接続すること、 によって達成される。The above-mentioned object is a vehicle ventilation device having an air supply fan at one end of an axis of one motor and an exhaust fan at the other end, wherein the motor is surrounded by a case, and one end of the motor in the radial direction is provided. The case is connected to an exhaust duct connected to an exhaust port opened in the vehicle interior, and the case on the other end side in the radial direction is connected to a second exhaust duct connected to the exhaust fan. Achieved by.

配置しているので、排気ファンの昇圧による冷却風の温
度上昇等の影響もなく、かつ、実質的に一定の温度に保
たれた車内からの排風によって冷却されるため、効率的
に冷却される。Since the motor is arranged on the upstream side of the exhaust fan in the exhaust flow path, there is no effect such as the temperature rise of the cooling air due to the pressure rise of the exhaust fan, and the inside of the vehicle is maintained at a substantially constant temperature. Since it is cooled by exhaust air, it is cooled efficiently.
また、排気流路は第２の排気ダクトによって流路が長
くなると共に屈曲しているので、低騒音化を図ることが
できるものである。Further, since the exhaust passage is bent and lengthened by the second exhaust duct, the noise can be reduced.

ある。Next, 11 is a required location inside the vehicle, that is, an indoor exhaust port that is installed in the vicinity of the floor surface of the guest room or deck, a toilet, etc.
It is for taking in a part of the air of the vehicle body as exhaust 17. Reference numeral 12 denotes an exhaust duct that connects one end of the indoor exhaust port 11 and that covers the outer periphery of the motor 1 at the other end and is connected to a case 4 for cooling the motor 1. An exhaust duct 13 has one end connected to the case 4 and the other end connected to the exhaust fan 3. The exhaust 17 is supplied to the indoor exhaust port 11, the exhaust duct 12, the case 4, the exhaust duct 13 by the exhaust fan 3.
It is guided to the exhaust fan 3 through the exhaust gas and is discharged to the outside of the vehicle through the exhaust port 14. Reference numeral 15 is an exhaust grill provided in the exhaust port 14.

て排気グリル15から車外に排出される。In such a configuration, the air supply 16 is sucked into the air supply fan 2 through the suction grill 5, the suction duct 6, and the air intake port 7 as described above, and is pressurized by the air supply fan 2 to supply the air supply duct 8, It is sent to the indoor air supply duct 10 through the indoor air port 9 and is supplied from the indoor air supply duct 10 to the air conditioner. On the other hand, the exhaust air 17 which is a part of the vehicle interior air is cooled through the indoor exhaust port 11 and the exhaust duct 12 in the case 4 that surrounds the outer periphery of the motor 1, and then the exhaust fan is exhausted through the exhaust duct 13. Three
Is exhausted to the outside of the vehicle from the exhaust grill 15 through the exhaust port 14 after being pressurized by the exhaust fan 3.
ところで、前記給気ファン２および排気ファン３は、
車両が高速でトンネル内を走行中に生じる車外圧変動圧
力よりも大きな圧力特性を有した高圧ファンである。By the way, the air supply fan 2 and the exhaust fan 3 are
It is a high-pressure fan having a pressure characteristic that is greater than the fluctuating pressure outside the vehicle that occurs when the vehicle is traveling in a tunnel at high speed.

の排熱によって上昇させることはない。According to such a configuration, the motor 1 is cooled by the exhaust gas 17, and is further cooled upstream of the exhaust fan 3 in the flow path of the exhaust gas 17. Therefore, the motor 1 is cooled by the exhaust 17 which is a part of the vehicle interior air that is always kept at a substantially constant temperature, and by the exhaust 17 before the pressure is raised by the exhaust fan 3 and the temperature rises. Can be efficiently cooled. On the other hand, the air supply 16 is guided by the air supply fan 2 to the air conditioner through the above-mentioned flow path and is supplied from the air conditioner as conditioned air into the passenger compartment. In this way, the supply air 16 is not used for cooling other devices, and the problem of increasing the heat load during cooling does not occur. That is, since the air supply fan 2 that takes in the air supply 16 into the vehicle is driven by the motor 1 and the motor 1 is cooled by the exhaust gas 17 as described above, the temperature of the air supply 16 is changed by the exhaust heat of other equipment. It does not rise.

である。Next, as described above, in the flow path of the exhaust gas 17, the path to the exhaust fan 3, that is, the indoor exhaust port 11, the exhaust duct 12,
Since the case 4 and the exhaust duct 13 are long, it is possible to prevent the noise of the exhaust fan 3 from propagating in the vehicle through the flow path. Also, the exhaust duct 13 will bend. Therefore, as compared with the conventional configuration in which the silencer is provided on the downstream side of the indoor exhaust port, it is not necessary to provide the silencer itself, and the number of parts can be reduced and the configuration can be simplified. Further, it is possible to prevent an unnecessary increase in passage resistance. By the way, in the above-mentioned structure, a muffling function may be added in the case 4, and in this case, even if the case 4 itself becomes slightly larger, it is more space or structural than the case where another muffler is separately installed. Will be advantageous. Moreover, since the connection position between the case 4 and the exhaust ducts 12 and 13 is in the horizontal direction, the overall height can be suppressed.

達成し得るものである。By the way, in the above-described configuration, the example in which the air supply fan 2 and the exhaust fan 3 are installed at both shaft ends of the motor 1 having both shafts has been described, but the air supply fan and the exhaust fan are provided at one shaft end side of the motor. Even if it is installed, the same effect as described above can be achieved.
