Description

本発明は、鉄道車両の調和空気ダクトの風量調整機構に関する。   The present invention relates to an air volume adjustment mechanism for a conditioned air duct of a railway vehicle.

鉄道車両は、乗客が居住する客室空間を快適な温熱環境にするために、空調装置によって温度調和した調和空気を客室空間へ供給する。この空調装置は、鉄道車両１両に対して、一般的には１台ないし２台搭載される。この空調装置から供給される調和空気を客室空間へ均等に配送するために、鉄道車両は調和空気ダクトを備えている。   Railway vehicles supply conditioned air conditioned by an air conditioner to the cabin space in order to make the cabin space where passengers live in a comfortable thermal environment. Generally, one or two air conditioners are mounted on one railway vehicle. In order to evenly distribute the conditioned air supplied from the air conditioner to the cabin space, the railway vehicle includes a conditioned air duct.

この調和空気ダクトは、客室へ流出する調和空気の量を客室全体で均一にするために、風量調整機構を備えている。例えば特許文献１には、調和空気ダクト内の空気吹出部に対して塞ぎ板を当てて空気吹出部の一部を塞ぎ、その開口度を調整する機構が開示されている（特許文献１参照）。   This conditioned air duct is provided with an air volume adjusting mechanism in order to make the amount of conditioned air flowing out to the cabin uniform throughout the cabin. For example, Patent Literature 1 discloses a mechanism for closing a part of the air blowing portion by applying a closing plate to the air blowing portion in the conditioned air duct and adjusting the opening degree (see Patent Literature 1). .

特開２０１１−１６２０８５号公報JP, 2011-162085, A

特許文献１には、空気吹出部の開口度を調整する塞ぎ板を備える調和空気ダクトが記載されている。しかし、このような塞ぎ板では、空気吹出部の開口度を所定の開口度にする調整作業に要する時間が多いことが課題であった。また、調整作業において発生する開口度の誤差（所定の開口度と実際の開口度の差）が大きいことも課題である。   Patent Document 1 describes a conditioned air duct including a closing plate for adjusting the opening degree of the air blowing portion. However, in such a closing plate, there is a problem that a large amount of time is required for the adjustment work for setting the opening degree of the air blowing portion to a predetermined opening degree. Another problem is that the error in the opening degree (the difference between the predetermined opening degree and the actual opening degree) generated in the adjustment operation is large.

本発明の目的は、空気吹出部の開口度の調整作業に要する時間を短くすることができ、また、開口度の誤差を小さくすることができるようにした調和空気ダクトを提供することにある。   An object of the present invention is to provide a conditioned air duct capable of shortening the time required for adjusting the opening degree of the air blowing portion and reducing the error of the opening degree.

上記課題を解決するために、代表的な本発明の調和空気ダクトの一つは、前記ダクトを構成する板材のうち少なくとも１枚の板材は空気が通過する複数の開孔から構成される第１多孔部を備え、前記第１多孔部に重ね置かれるとともに第２多孔部を有する可動板と、前記板材の上面に沿って回動可能に可動板を保持するボルトと、を有するダクトであって、第１多孔部と、第２多孔部と、を連通する総合開口率が可動板の回動角度で決定されることにより達成される。   In order to solve the above-mentioned problem, one of the representative conditioned air ducts of the present invention is a first in which at least one plate material among the plate materials constituting the duct is composed of a plurality of openings through which air passes. A duct comprising a porous part, a movable plate placed on the first porous part and having a second porous part, and a bolt holding the movable plate so as to be rotatable along the upper surface of the plate member. This is achieved by determining the overall aperture ratio for communicating the first porous portion and the second porous portion by the rotation angle of the movable plate.

本発明によれば、空気吹出部の開口度の調整作業に要する時間が短く、また、開口度の誤差が小さい調和空気ダクトを提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the time which adjustment time of the opening degree of an air blowing part requires is short, and the conditioned air duct with a small opening degree error can be provided.

以下、実施例を図面を用いて説明する。   Hereinafter, examples will be described with reference to the drawings.

以下、本発明の一実施例を図１から図９を用いて説明する。まず、鉄道車両に係る各方向を、鉄道車両の幅方向（枕木方向）５１０、鉄道車両の長手方向５２０、鉄道車両の高さ方向５３０とし、以下、それぞれ幅方向５１０、長手方向５２０、高さ方向５３０と省略して記載する場合がある。   An embodiment of the present invention will be described below with reference to FIGS. First, each direction relating to the railway vehicle is defined as a width direction (sleeper direction) 510 of the railway vehicle, a longitudinal direction 520 of the railway vehicle, and a height direction 530 of the railway vehicle, and hereinafter, the width direction 510, the longitudinal direction 520, and the height, respectively. The direction may be abbreviated as 530.

図１は、本発明が搭載された鉄道車両１の斜視図である。鉄道車両１は、床面をなす台枠１１と、この台枠１１の幅方向５１０の両端部に立設された側構体１２と、台枠１１の長手方向５２０の両端部に立設された妻構体１３と、側構体１２と妻構体１３の高さ方向５３０の上端部に載置された屋根構体１４から構成される。   FIG. 1 is a perspective view of a railway vehicle 1 on which the present invention is mounted. The railcar 1 is erected on a frame 11 forming a floor, side structures 12 erected on both ends of the frame 11 in the width direction 510, and both ends of the frame 11 in the longitudinal direction 520. It is comprised from the roof structure 14 mounted in the upper end part of the height direction 530 of the wife structure 13 and the side structure 12 and the wife structure 13. FIG.

鉄道車両１を構成する台枠１１の長手方向５２０の両端部は、軌道上を転動する輪軸を備える台車（図示していない）によって支持される。鉄道車両１を構成する側構体１２には、窓１２２および乗客の乗降に供される出入り台１２４が設けられている。出入り台１２４には、側引戸が鉄道車両１の長手方向に沿って開閉可能に設けられている。   Both ends in the longitudinal direction 520 of the frame 11 constituting the railway vehicle 1 are supported by a carriage (not shown) having a wheel shaft that rolls on the track. The side structure 12 constituting the railway vehicle 1 is provided with a window 122 and an entrance / exit platform 124 for passengers to get on and off. The entrance / exit 124 is provided with a side sliding door that can be opened and closed along the longitudinal direction of the railway vehicle 1.

鉄道車両１は、空調装置２ａ、２ｂを備えている。空調装置２ａ、２ｂは、冷媒が循環する冷凍サイクルを構成する圧縮機、室外熱交換器、室内熱交換器などからなる冷凍サイクルと、室外熱交換器に併設される室外送風機と、室内熱交換器に併設される室内送風機と、暖房用ヒータ（室内熱交換器に併設される）と、車内の空気を車外へ排気する排気送風機から構成される。   The railway vehicle 1 includes air conditioners 2a and 2b. The air conditioners 2a and 2b include a refrigeration cycle composed of a compressor, an outdoor heat exchanger, an indoor heat exchanger, and the like that constitute a refrigeration cycle in which refrigerant circulates, an outdoor blower attached to the outdoor heat exchanger, and indoor heat exchange. It is comprised from the indoor air blower attached to a heater, the heater for heating (it is attached to an indoor heat exchanger), and the exhaust air fan which exhausts the air in a vehicle outside the vehicle.

鉄道車両１の天井部には、車内の空気を各空調装置の内部に取り入れるリターンダクトと、各空調装置で温度・湿度が調和された調和空気を客室等へ送風する調和空気ダクト３２と、車内から車外へ排出する空気を空調装置へ導く排気空気ダクトが配設されている。   On the ceiling of the railway vehicle 1, there are a return duct for taking the air in the vehicle into each air conditioner, a conditioned air duct 32 for blowing conditioned air in which the temperature and humidity are harmonized by each air conditioner to the cabin, etc. An exhaust air duct that guides air discharged from the vehicle to the air conditioner is disposed.

図２は、調和空気ダクト３２の斜視図である。調和空気ダクト３２は、客室全長に配設されている。調和空気ダクト３２は、上面に流入口３４ａと流入口３４ｂを備え、空調装置２ａと空調装置２ｂとからそれぞれ調和空気６００が供給される。調和空気ダクト３２の下部には、長手方向５２０に連続的に設けた流出口３６があり、ここから客室内へ調和空気６００を供給する。   FIG. 2 is a perspective view of the conditioned air duct 32. The conditioned air duct 32 is disposed along the entire length of the passenger cabin. The conditioned air duct 32 includes an inlet 34a and an inlet 34b on the upper surface, and conditioned air 600 is supplied from the air conditioner 2a and the air conditioner 2b, respectively. At the lower part of the conditioned air duct 32, there is an outflow port 36 provided continuously in the longitudinal direction 520, from which conditioned air 600 is supplied into the cabin.

図３は、調和空気ダクト３２の内部の空気吹出部周辺を詳細に示す斜視図である。調和空気６００は、調和空気ダクト３２の空気吹出部３９ａ、３９ｂ、３９ｃ、３９ｄを経て、客室へ送風される。客室内の長手方向５２０の調和空気の風量分布を均一にするためには、空気吹出部３９ａ、３９ｂ、３９ｃ、３９ｄの開口度を調整することが必要である。図示していないが、空気吹出部は図示している空気吹出部３９ａ、３９ｂ、３９ｃ、３９ｄの他に多数ある。そのため、鉄道車両１の全ての空気吹出部の開口度を調整する作業は、多くの工数を要する作業である。   FIG. 3 is a perspective view showing in detail the vicinity of the air blowing portion inside the conditioned air duct 32. The conditioned air 600 is blown to the cabin through the air blowing portions 39a, 39b, 39c, and 39d of the conditioned air duct 32. In order to make the air volume distribution of the conditioned air in the longitudinal direction 520 in the cabin uniform, it is necessary to adjust the opening degree of the air blowing portions 39a, 39b, 39c, and 39d. Although not shown, there are many air blowing parts in addition to the air blowing parts 39a, 39b, 39c, and 39d shown in the figure. Therefore, the work of adjusting the opening degree of all the air blowing parts of the railway vehicle 1 is a work that requires a lot of man-hours.

図４は、風量調整板４２を側板４０と平行に固定したときの空気吹出部３９ａの詳細図である。空気吹出部３９ａは、調和空気ダクト３２の側板４０、風量調整板４２、側板４０に風量調整板を回転可能に保持するための支点ボルト４４、側板４０と風量調整板４２の角度を固定するための固定ボルト４６より構成される。   FIG. 4 is a detailed view of the air blowing portion 39a when the air volume adjusting plate 42 is fixed in parallel with the side plate 40. FIG. The air blowing part 39a fixes the angle between the side plate 40 of the conditioned air duct 32, the air volume adjusting plate 42, the fulcrum bolt 44 for rotatably holding the air volume adjusting plate on the side plate 40, and the angle of the side plate 40 and the air volume adjusting plate 42. The fixing bolt 46 of FIG.

図５は、側板４０を示す図である。側板４０は、支点ボルト４４と固定ボルト４６を締結するためのブラインドナット４８を備えている。ブラインドナット４８は、溶接ナットであってもよい。また、側板４０は、多数の丸孔により構成される第一の多孔部４０２を備えている。   FIG. 5 is a view showing the side plate 40. The side plate 40 includes a blind nut 48 for fastening the fulcrum bolt 44 and the fixing bolt 46. The blind nut 48 may be a weld nut. Further, the side plate 40 includes a first porous portion 402 constituted by a large number of round holes.

図６は、風量調整板４２を示す図である。風量調整板４２は、多数の丸孔により構成される第二の多孔部４２２を備えている。また、風量調整板４２は、支点ボルトが貫通するための丸孔４２４と、固定ボルトが貫通するための長孔４２６を備えている。   FIG. 6 is a view showing the air volume adjusting plate 42. The air volume adjusting plate 42 includes a second porous portion 422 constituted by a large number of round holes. The air volume adjusting plate 42 includes a round hole 424 for the fulcrum bolt to pass therethrough and a long hole 426 for the fixing bolt to pass therethrough.

以上の構成からなる空気吹出部３９ａは、図３に示したように、第一の多孔部４０２と第二の多孔部４２２が連通した開口４９を形成する。開口４９から調和空気が吹き出す構造となる。また、固定ボルト４６の締結を緩めることにより、支点ボルト４４を回転中心として、風量調整板４２を容易に回転させることができるので、風量調整板４２と側板４０の角度７００を任意の角度とすることができる。   As shown in FIG. 3, the air blowing portion 39 a configured as described above forms an opening 49 in which the first porous portion 402 and the second porous portion 422 communicate with each other. The conditioned air is blown out from the opening 49. In addition, by loosening the fastening of the fixing bolt 46, the air volume adjusting plate 42 can be easily rotated around the fulcrum bolt 44, so that the angle 700 between the air volume adjusting plate 42 and the side plate 40 is set to an arbitrary angle. be able to.

図７は、風量調整板４２と側板４０の角度７００を１度としたときの図である。この場合は、第一の多孔部４０２と第二の多孔部４２２が連通した開口４９の面積が、図３に比べて小さくなる。このことによって、ダクトから吹き出す調和空気量を少なくすることができる。   FIG. 7 is a view when the angle 700 between the air volume adjusting plate 42 and the side plate 40 is 1 degree. In this case, the area of the opening 49 where the first porous portion 402 and the second porous portion 422 communicate with each other is smaller than that in FIG. As a result, the amount of conditioned air blown out of the duct can be reduced.

図８、図９は、それぞれ、風量調整板４２と側板４０の角度７００を２度、３度としたときの図である。このように、角度７００を大きくすることで開口４９の面積を小さくすることができる。   8 and 9 are views when the angle 700 between the air volume adjusting plate 42 and the side plate 40 is set to 2 degrees and 3 degrees, respectively. Thus, by increasing the angle 700, the area of the opening 49 can be reduced.

なお、上記では、調和空気ダクト３２が鉄道車両１の天井に艤装された状態での調整作業を説明したが、空気吹出部３９ａの開口度調整作業は、調和空気ダクト３２を鉄道車両１に艤装していない状態で行う場合もある。本発明は、調和空気ダクト３２を鉄道車両１に艤装していない状態でも適用可能である。   In the above description, the adjustment work in a state where the conditioned air duct 32 is mounted on the ceiling of the railway vehicle 1 has been described. However, the opening degree adjustment work of the air blowing portion 39a is performed by mounting the conditioned air duct 32 on the railway vehicle 1. In some cases it is not done. The present invention can be applied even in a state where the conditioned air duct 32 is not mounted on the railway vehicle 1.

また、上記では、本発明の風量調整構造を調和空気を通風させるための調和空気ダクト３２に適用した例を示したが、本風量調構造は、リターンダクトなどのダクトの風量調整の際にも使用できる。本発明の風量調整構造を適用するダクトの種別を限定するものではない。   Moreover, although the example which applied the air volume adjustment structure of this invention to the conditioned air duct 32 for ventilating conditioned air was shown above, this air volume adjustment structure is also in the case of air volume adjustment of ducts, such as a return duct. It can be used. The type of duct to which the air volume adjustment structure of the present invention is applied is not limited.

本実施例の構成によれば、例えば、鉄道車両１に空気吹出部が多数ある場合であっても、開口度の調整作業として風量調整板と側板との角度を設定する容易な作業であるので、調整作業に要する時間を従来の調整作業と比べて短くすることができる。また、例えば、空気が通過する側板に重ねて設けられる風量調整板により開口の面積を調整するので、開口度の誤差を小さくすることができる。   According to the configuration of the present embodiment, for example, even when the railway vehicle 1 has a large number of air blowing portions, it is an easy operation to set the angle between the air volume adjusting plate and the side plate as the opening adjustment operation. The time required for the adjustment work can be shortened compared to the conventional adjustment work. Further, for example, since the area of the opening is adjusted by an air volume adjusting plate provided to be overlapped with the side plate through which air passes, an error in the opening degree can be reduced.

図１０は、本発明の別の実施形態の空気吹出部３９ａを示す図である。本実施例の空気吹出部３９ａは、実施例１と同様の構成要素から構成される。本実施例が実施例１と異なる点は、本実施例の風量調整板４２の第二の多孔部４２２は、丸孔だけではなく、多角形の孔４２８ａ、４２８ｂ、４２８ｃ、４２８ｄを備えている。これにより、多角形の孔４２８ａ、４２８ｂ、４２８ｃ、４２８ｄを他の丸孔より識別しやすくなる。   FIG. 10 is a diagram showing an air blowing portion 39a according to another embodiment of the present invention. The air blowing part 39a of the present embodiment is composed of the same components as in the first embodiment. The difference between the present embodiment and the first embodiment is that the second porous portion 422 of the air volume adjusting plate 42 of the present embodiment includes not only round holes but also polygonal holes 428a, 428b, 428c, and 428d. . This makes it easier to identify the polygonal holes 428a, 428b, 428c, and 428d than other round holes.

この結果、風量調整板４２と側板４０の角度７００を所定の角度にする作業においては、予め丸棒を用意したうえで、例えば、「風量調整板４２の五角形の孔と、側板４０の孔に、ちょうど丸棒が入る角度」とすることで、角度７００を分度器等の器具を用いて測定しなくても、容易に、精度よく、所定の角度に調整することができる。   As a result, in the operation of setting the angle 700 between the air volume adjusting plate 42 and the side plate 40 to a predetermined angle, after preparing a round bar in advance, for example, “the pentagonal hole of the air volume adjusting plate 42 and the hole of the side plate 40 By just setting the angle at which the round bar enters, it is possible to easily and accurately adjust the angle 700 to a predetermined angle without measuring the angle 700 using an instrument such as a protractor.

なお、本実施例では、丸孔との識別のために多角形の孔を設ける例を示しているが、丸孔との識別を容易にすることができるのであれば、必ずしも孔の形状が多角形である必要はなく、本発明の孔の形状をなんら限定する意図はない。   In this embodiment, an example in which a polygonal hole is provided for identification with a round hole is shown. However, if the identification with a round hole can be facilitated, the shape of the hole is not necessarily large. It does not need to be square and is not intended to limit the shape of the hole of the present invention.

図１１は、本発明の別の実施形態の空気吹出部３９ａを示す図である。本実施例の空気吹出部３９ａは、実施例１と同様の構成要素から構成される。本実施例が実施例１と異なる点は、本実施例は、固定ボルト４６を１本のみ備える点である。これにより、風量調整板４２を固定する際の必要工数は、固定ボルト４６を２本備えるときに比べて少なくすることができる。   FIG. 11 is a diagram showing an air blowing portion 39a according to another embodiment of the present invention. The air blowing part 39a of the present embodiment is composed of the same components as in the first embodiment. The present embodiment is different from the first embodiment in that the present embodiment includes only one fixing bolt 46. Thereby, the required man-hour at the time of fixing the air volume adjusting plate 42 can be reduced compared with the case where the two fixing bolts 46 are provided.

実施例１ないし３に示したように、本発明を適用したダクトは、例えば、下記の特徴を有する。   As shown in Examples 1 to 3, the duct to which the present invention is applied has, for example, the following characteristics.

空気を分配するためのダクト（例えば、調和空気ダクト３２）であって、上記ダクトを構成する板材のうち少なくとも１枚の板材（例えば、側板４０）は空気が通過する複数の開孔から構成される第１多孔部（例えば、第一の多孔部４０２）を備え、上記第１多孔部に重ね置かれるとともに第２多孔部（例えば、第二の多孔部４２２）を有する可動板（例えば、風量調整板４２）と、上記板材の上面に沿って回動可能に可動板を保持するボルト（例えば、支点ボルト４４および固定ボルト４６）と、を有するダクトであって、第１多孔部と、第２多孔部と、を連通する総合開口率（例えば、調和空気ダクト３２の全ての空気吹出部から通過できる調和空気を総合した流量の割合を示す開口率）が上記可動板の回動角度（例えば、各空気吹出部における風量調整板と側板との角度）で決定されることを特徴とする。   A duct for distributing air (for example, the conditioned air duct 32), and at least one plate (for example, the side plate 40) among the plates constituting the duct is configured by a plurality of openings through which air passes. A movable plate (for example, air volume) having a first porous portion (for example, the first porous portion 402) and having a second porous portion (for example, the second porous portion 422) overlaid on the first porous portion. The adjustment plate 42) and a duct (for example, a fulcrum bolt 44 and a fixed bolt 46) that hold the movable plate so as to be rotatable along the upper surface of the plate member. The total aperture ratio that communicates with the two porous portions (for example, the aperture ratio that indicates the ratio of the flow rate of the total amount of conditioned air that can pass from all the air blowing portions of the conditioned air duct 32) is the rotation angle (for example, , Each air outlet Characterized in that it is determined by the definitive angle between air volume adjusting plate and the side plate).

また、例えば、第２多孔部の開孔のうち少なくともひとつの開孔の形状が円形であって、少なくともひとつの開孔の形状が多角形であることを特徴としてもよい。   Further, for example, at least one of the openings of the second porous portion may be circular, and at least one of the openings may be polygonal.
