腰掛下の床面から導入された空調空気の主流方向を腰掛背面に沿った方向とすることにより、腰掛前方への空調空気の流れによる乗客足元の流速を低減し、過剰な温度低下を回避する。さらには、車室内の気流感および温度ムラを低減し、居住性の向上を図る。   By setting the main flow direction of the conditioned air introduced from the floor under the seat to the direction along the back of the seat, the flow speed of the passenger's feet due to the flow of air-conditioned air to the front of the seat is reduced, and an excessive temperature drop is avoided. . Furthermore, the airflow feeling and temperature unevenness in the passenger compartment are reduced, and the comfort is improved.

以下に、本発明の第１形態について図面を用いて説明する。   Below, the 1st form of this invention is demonstrated using drawing.

〔発明の実施の第１形態〕
図１、図２および図３に本発明を実施する鉄道車両の車室１を示す。図１は車両の横断面を示す図、図２は車両中心断面を示す図、図３は車両を上から見た断面図である。 [First Embodiment of the Invention]
1, 2 and 3 show a passenger compartment 1 of a railway vehicle for carrying out the present invention. 1 is a cross-sectional view of the vehicle, FIG. 2 is a cross-sectional view of the center of the vehicle, and FIG. 3 is a cross-sectional view of the vehicle as viewed from above.

図１、図２および図３に示すように車室１には、床面２の上に進行方向に対して左右に腰掛３が設けられ、それぞれの側には側窓４が設けられている。また、側窓４の上部には荷棚５が設けられている。腰掛３下の床面２に空調空気を吹き出す吹き出し口６を、荷棚５の上部に車室１内の空気を車室１の外部に排気する排気口７を備え、車室１内に吹出した空調空気が腰掛３下の床面２から荷棚５上部に上昇して排気されるようになっている。この空調空気の上昇流れと車室内の熱負荷による上昇流れが一致している。本発明では、床面２から空調空気を吹き出すため、空調空気の吹き出し口６に合わせて床面２の下部に空調空気の風道８を備えている。   As shown in FIGS. 1, 2, and 3, the passenger compartment 1 is provided with a seat 3 on the floor 2 on the left and right of the traveling direction, and a side window 4 is provided on each side. . In addition, a cargo shelf 5 is provided on the upper side of the side window 4. A blow-out port 6 for blowing conditioned air to the floor surface 2 under the stool 3 is provided, and an exhaust port 7 for exhausting the air in the passenger compartment 1 to the outside of the passenger compartment 1 is provided at the upper part of the cargo rack 5. The conditioned air rises from the floor surface 2 below the seat 3 to the upper part of the cargo rack 5 and is exhausted. This rising flow of conditioned air coincides with the rising flow caused by the heat load in the passenger compartment. In the present invention, in order to blow out the conditioned air from the floor surface 2, an air passage 8 for the conditioned air is provided at the lower part of the floor surface 2 in accordance with the outlet 6 of the conditioned air.

本実施例では、空調空気の吹き出し口６から腰掛３の座面下の空間に整流機構として整流板９を備えている。空調空気の吹き出し口６から吹出した空調空気の主流の方向は、整流板９により腰掛３の背面側に誘導される。この整流板９は、図２に示すように整流板９と腰掛３の背面が連続的に形成されており、腰掛３の背面側に誘導された空調空気の流れが乱されることなく、腰掛３の背面に沿って上昇していく。   In this embodiment, a rectifying plate 9 is provided as a rectifying mechanism in a space below the seat surface of the seat 3 from the air-conditioned air outlet 6. The direction of the main flow of the conditioned air blown out from the conditioned air outlet 6 is guided to the back side of the seat 3 by the rectifying plate 9. 2, the current plate 9 and the back surface of the seat 3 are continuously formed as shown in FIG. 2, and the flow of conditioned air guided to the back surface side of the seat 3 is not disturbed. Ascending along the back of 3.

また、この整流板９は、車両の進行方向が変わったときに行われる腰掛の１８０°回転に対応するため、腰掛回転に応じて、空調空気の主流の方向を腰掛背面に沿った方向に変化させる整流板９の回転機構１０を備えている。この回転機構１０は図示しない腰掛３の回転機構に連動して動作する。   In addition, since the rectifying plate 9 corresponds to the 180 ° rotation of the seat performed when the traveling direction of the vehicle changes, the mainstream direction of the conditioned air changes in the direction along the seat back according to the seat rotation. A rotation mechanism 10 for the rectifying plate 9 is provided. The rotating mechanism 10 operates in conjunction with a rotating mechanism of the seat 3 (not shown).

具体的には、図４に示すように、整流板９と一体に構成されたリングギヤ１１を円形に構成された空調の吹き出し口６に嵌合し、整流板９の回転機構１０によりリングギヤ１１を回転させることにより、整流板９を１８０°回転させることが出来る。   Specifically, as shown in FIG. 4, a ring gear 11 formed integrally with the rectifying plate 9 is fitted into a circular air-conditioning outlet 6, and the ring gear 11 is moved by the rotating mechanism 10 of the rectifying plate 9. By rotating, the current plate 9 can be rotated 180 °.

また、図５に示すように、整流板９と回転機構１２を係合し、係合している軸を中心として回転機構１２により整流板９を１８０°回転させるような機構であっても構わない。なお、回転機構１２は図示しない腰掛３の回転機構に連動して動作する。   Further, as shown in FIG. 5, the mechanism may be a mechanism in which the rectifying plate 9 and the rotating mechanism 12 are engaged and the rectifying plate 9 is rotated by 180 ° by the rotating mechanism 12 around the engaged shaft. Absent. The rotating mechanism 12 operates in conjunction with a rotating mechanism of the seat 3 (not shown).

以上に述べた整流板９の作用により、空調空気の吹き出し口６から吹き出した空調空気が、腰掛３の座面下に衝突し、腰掛３の前方向に流れることによる乗客足元の過大な流速および乗客足元の温度の過剰な低下を回避することが出来る。   Due to the action of the rectifying plate 9 described above, the conditioned air blown out from the conditioned air outlet 6 collides under the seat surface of the stool 3 and flows in the forward direction of the stool 3, and an excessive flow velocity at the passenger's feet An excessive decrease in the temperature at the passenger's feet can be avoided.

整流板９は、整流板９の鉛直上方からの投影写像が、空調空気の吹き出し口６の投影写像を覆う構成であることが望ましい。これにより、吹出された空調空気が整流板９から外れないため、空調空気の主流の方向が効果的に腰掛３の背面方向に誘導される。よって、上述したような腰掛３の前方向に流れる空調空気による乗客足元の過大な流速および温度の過剰な低下を回避することが出来る。   It is desirable that the rectifying plate 9 has a configuration in which the projected map from above the rectifying plate 9 covers the projected map of the outlet 6 of the conditioned air. Thereby, since the blown-out conditioned air does not come off from the rectifying plate 9, the direction of the main flow of the conditioned air is effectively guided toward the back surface of the seat 3. Therefore, it is possible to avoid an excessive decrease in the flow velocity and temperature at the passenger's feet due to the conditioned air flowing in the forward direction of the seat 3 as described above.

また、本発明では床面２から空調空気を吹出しているため、乗客の不注意等により、空調空気の吹き出し口６から風道８内に異物が落下する恐れがある。それによる不具合の発生を回避するため、空調空気の吹き出し口６に異物落下の防止機構として、メッシュ形状の金網を備えても構わない。メッシュの大きさは、落下する可能性のある異物の大きさと、吹き出し口６で発生する圧力損失等を考慮し、決定する必要がある。
また、吹出し口の開口面積を変更することで風量調整を行なうことができる。 Further, in the present invention, the conditioned air is blown out from the floor surface 2, so that foreign matters may fall into the air passage 8 from the conditioned air outlet 6 due to the carelessness of passengers. In order to avoid the occurrence of problems due to this, a mesh-shaped wire net may be provided at the air outlet 6 of the conditioned air as a foreign matter fall prevention mechanism. The size of the mesh needs to be determined in consideration of the size of a foreign substance that may fall and the pressure loss that occurs at the outlet 6.
Further, the air volume can be adjusted by changing the opening area of the outlet.

〔発明の実施の第２形態〕
図６は本発明を実施する鉄道用車両の上方からの断面図を示している。車両の横断面および車両中心断面は、図１および図２に示すものと同様である。図６に示すように車室１には、床面２上に進行方向に対して左右に腰掛３が設けられ、それぞれの側には側窓４が設けられている。また、側窓４の上部には荷棚５が設けられている。腰掛３下の床面２に空調空気を吹き出す吹き出し口６を、荷棚５の上部に車室１内の空気を車室の１外部に排気する排気口７を備え、車室１内に吹出した空調空気が腰掛３下の床面２から車室１の荷棚５上部に上昇して排気されるようになっている。この空調空気の上昇流れと車室内の熱負荷による上昇流れが一致している。本発明では、床面２から空調空気を吹き出すため、吹き出し口６に合わせて車室の床面２の下部に空調空気の風道８を備えている。 [Second Embodiment of the Invention]
FIG. 6 shows a cross-sectional view from above of a railway vehicle embodying the present invention. The cross section of the vehicle and the cross section of the vehicle center are the same as those shown in FIGS. As shown in FIG. 6, a seat 3 is provided on the floor 2 on the left and right of the traveling direction on the floor surface 2, and side windows 4 are provided on the respective sides. In addition, a cargo shelf 5 is provided on the upper side of the side window 4. A blowout port 6 for blowing air-conditioned air to the floor surface 2 under the stool 3 and an exhaust port 7 for exhausting the air in the passenger compartment 1 to the outside of the passenger compartment 1 at the upper part of the cargo rack 5 The conditioned air rises from the floor 2 under the seat 3 to the upper part of the cargo rack 5 of the passenger compartment 1 and is exhausted. The rising flow of the conditioned air coincides with the rising flow caused by the heat load in the passenger compartment. In the present invention, in order to blow out the conditioned air from the floor surface 2, an air passage 8 for the conditioned air is provided in the lower part of the floor surface 2 of the passenger compartment in accordance with the outlet 6.

本実施例では、空調空気の吹き出し口６に整流機構として整流フィン１３を備えている。空調空気の吹き出し口６から吹出した空調空気の主流の方向は、整流フィン１３により腰掛３の背面側に誘導され、腰掛３の背面に沿って上昇していく。また、この整流フィン１３は、車両の進行方向が変わったときに行われる腰掛の１８０°回転に対応するため、腰掛回転に合わせて、空調空気の主流の流速方向を腰掛背面に沿った方向に変化させる整流フィン１３の回転機構１４を備えている。この回転機構１４は図示しない腰掛３の回転機構に連動して動作する。   In the present embodiment, the air-conditioning air outlet 6 is provided with a rectifying fin 13 as a rectifying mechanism. The direction of the main flow of the conditioned air blown from the conditioned air outlet 6 is guided to the back side of the stool 3 by the rectifying fins 13 and rises along the back surface of the stool 3. Further, since the rectifying fin 13 corresponds to the 180 ° rotation of the seat performed when the traveling direction of the vehicle changes, the flow direction of the main flow of the conditioned air is changed to the direction along the seat back according to the seat rotation. The rotating mechanism 14 of the rectifying fin 13 to be changed is provided. The rotating mechanism 14 operates in conjunction with a rotating mechanism of the seat 3 (not shown).

具体的には、図７に示すように、整流フィン１３はそれぞれの中心において空調空気の吹き出し口６の縁に支持されており、さらに、整流フィン１３の先端部分と係合した支持棒１５に、整流フィン１３の回転機構１４が係合しており、回転機構１４が支持棒１５を前後に駆動することにより、腰掛回転後においても、腰掛回転前と同様に、空調空気の主流の方向を腰掛背面方向とすることができる。   Specifically, as shown in FIG. 7, the rectifying fins 13 are supported by the edges of the air-conditioned air outlets 6 at the respective centers, and further on the support rods 15 engaged with the tip portions of the rectifying fins 13. The rotation mechanism 14 of the rectifying fin 13 is engaged, and the rotation mechanism 14 drives the support rod 15 back and forth, so that the direction of the main flow of conditioned air after the sitting rotation is the same as before the sitting rotation. It can be the seat back direction.

以上に述べた整流フィン１３の作用により、空調空気の吹き出し口６から吹き出した空調空気が、腰掛３の座面下に衝突し、腰掛３の前方向に流れることによる乗客足元の過大な流速および乗客足元の温度の過剰な低下を回避することが出来る。   Due to the action of the rectifying fins 13 described above, the conditioned air blown out from the conditioned air outlet 6 collides under the seat surface of the stool 3 and flows in the forward direction of the stool 3, and an excessive flow velocity at the passenger's feet An excessive decrease in the temperature at the passenger's feet can be avoided.

また、本発明では床面２から空調空気を吹出しているため、乗客の不注意等により、空調空気の吹き出し口６から風道８内に異物が落下する恐れがある。それによる不具合の発生を回避するため、空調空気の吹き出し口６に異物落下の防止機構として、メッシュ形状の金網を備えても構わない。メッシュの大きさは、落下する可能性のある異物の大きさと、吹き出し口６で発生する圧力損失等を考慮し、決定する必要がある。   Further, in the present invention, the conditioned air is blown out from the floor surface 2, so that foreign matters may fall into the air passage 8 from the conditioned air outlet 6 due to the carelessness of passengers. In order to avoid the occurrence of problems due to this, a mesh-shaped wire net may be provided in the air-conditioning air outlet 6 as a foreign matter fall prevention mechanism. The size of the mesh needs to be determined in consideration of the size of a foreign substance that may fall and the pressure loss that occurs at the outlet 6.
