Description

この発明は、電車、列車、特に新幹線（登録商標）車両や長距離用の電車、列車内に設置され、小便等の汚水を処理する車両用汚水処理装置、詳細には小便等の汚水を汚水受器から汚水を重力によって汚物タンクまで落下させる方式の車両用汚水処理装置に関する。 The present invention relates to trains, trains, particularly Shinkansen (registered trademark) vehicles, long-distance trains, sewage treatment devices for vehicles that are installed in trains and treat sewage such as urine, and more specifically, sewage such as urine is sewed The present invention relates to a vehicle sewage treatment apparatus that drops sewage from a receiver to a waste tank by gravity.

新幹線（登録商標）車両、長距離用電車、列車内に設置される小便用の車両用汚水処理装置は、従来、小便器に為された汚水が汚水管を経由して汚物タンクへ流す方式として、重力による重力落下式、又は真空で吸引する真空吸引式の２通りの方式によって行われており、車内と車外の気圧差のための逆流を防止するため、汚水管の中間に１つの弁体を設けていたことは知られている。（従来技術１） Shinkansen (registered trademark) vehicles, long-distance trains, and sewage sewage treatment equipment for urinals installed in trains have traditionally been used as a method for flowing sewage from a urinal to a filth tank via a sewage pipe. In order to prevent backflow due to the pressure difference between the inside and outside of the vehicle, one valve element is placed in the middle of the sewage pipe. It is known that (Prior art 1)

更に、改良された小便用の車両用汚水処理装置は、真空圧送方式によるもので、小便器にされた汚水が汚水管を経由して一度中間タンクに入り、更に中間タンクに内圧を加えることにより汚水管から汚物タンクに流されている方式も知られていた。そしてこのような真空圧送方式は、中間タンクの上流側と下流側の汚水管にそれぞれ弁体を設け中間タンクを加圧減圧することにより汚水を、小便器から汚物タンクへ圧送する構造であった。（従来技術２）   Furthermore, the improved sewage treatment apparatus for vehicles for urine is based on the vacuum pressure feeding system, and the sewage made into the urinal once enters the intermediate tank via the sewage pipe and further applies internal pressure to the intermediate tank. There was also known a method in which the wastewater pipes flowed into the waste tank. And such a vacuum pumping system has a structure in which sewage is pumped from the urinal to the filth tank by providing valve bodies in the upstream and downstream sewage pipes of the intermediate tank and pressurizing and depressurizing the intermediate tank . (Prior art 2)

すなわち、従来技術２の小便用の車内用汚水処理装置は、第１段階として小便器が使用されると中間タンク内を減圧することにより、上流側弁体を開き、下流側弁体を閉め、中間タンクへ汚水を吸引する。中間タンクに汚水が入ると、次に第２段階として上流側弁体を閉めてから中間タンク内を加圧し、次に下流側弁体を開いて汚水を中間タンクから汚物タンクへ圧送していた。また、特開平６−１９９２３４号公報（従来技術３）には高速走行を行なう新幹線（登録商標）車両は乗客の不快感（耳への不快感など）をなくすための車両用換気装置が開示されている。 That is, the in-car sewage treatment apparatus for urine of Prior Art 2 opens the upstream valve body and closes the downstream valve body by decompressing the intermediate tank when the urinal is used as the first stage, Aspirate sewage into the intermediate tank. When sewage enters the intermediate tank, the upstream valve body was closed as the second stage, and then the inside of the intermediate tank was pressurized. Next, the downstream valve body was opened and the sewage was pumped from the intermediate tank to the filth tank. . Japanese Laid-Open Patent Publication No. Hei 6-199234 (Prior Art 3) discloses a vehicle ventilator that eliminates passenger discomfort (such as discomfort to the ear ) of Shinkansen (registered trademark) vehicles that run at high speed. ing.

長距離用電車や列車内に設置される小便用の車両用汚水処理装置、特に新幹線（登録商標）車両に設置される小便用の車両用汚水処理装置において、乗客が使用する小便器は車内に設置され、小便等の汚水が溜められる汚物タンクは車外の底部に設けられている。 Vehicular sewage treatment apparatus for urine to be installed in the long-distance train or a train, in particular Shinkansen (TM) vehicle sewage treatment apparatus for urine to be installed in a vehicle, urinal passengers used in vehicle A filth tank that is installed and collects sewage such as urine is provided at the bottom of the vehicle.

そして乗客が使用する車内、特に高速走行を行う新幹線（登録商標）車両内は、乗客の耳等に感じる不快感を無くすため従来技術３に開示されているような車両用換気装置を使用して車内圧力が一定範囲で保たれている。しかし汚物タンクが設置されている車外底部は、この圧力調整が行なわれていない。そのため高速列車同士のすれ違い時や車両のトンネルへの突入時やトンネル内に入り走行する状態になると、急激に汚物タンクにも高圧が掛かることになり、汚物タンク内の圧力も高くなる。例えば高速走行時の新幹線（登録商標）が明かり区間（通常の地上部）で、高速列車同士のすれ違い時の場合に、汚物タンクに掛かる圧力が通常の大気圧にプラスして４００ｍｍＡｑまで上がる状態も発生し、さらにトンネル突入時やトンネル内での走行時では、汚物タンクに掛かる圧力が大気圧にプラスして１２００ｍｍＡｑまで上がる状態も発生する可能性があった。 And, in a vehicle used by passengers, especially in a Shinkansen (registered trademark) vehicle that runs at high speed, a vehicle ventilator as disclosed in Prior Art 3 is used to eliminate discomfort felt by passengers' ears and the like. The in-car pressure is maintained within a certain range. However, this pressure adjustment is not performed at the bottom of the vehicle where the filth tank is installed. Therefore, when the high-speed trains pass each other, when the vehicle enters the tunnel or enters the tunnel, the high pressure is also applied to the filth tank, and the pressure in the filth tank also increases. For example, when the Shinkansen (registered trademark) during high-speed running is a light section (normal ground) and the high-speed trains pass each other, the pressure applied to the filth tank increases to 400 mmAq in addition to the normal atmospheric pressure. In addition, when entering the tunnel or traveling in the tunnel, there is a possibility that the pressure applied to the waste tank increases to 1200 mmAq in addition to atmospheric pressure.

この圧力により、上記従来技術１のように弁体が１つであると、トンネル内での走行等により汚物タンクへ高圧が掛かると、汚水管内の汚水が圧力の低い車内に設置された汚水受器である小便器へ逆流することがあるという問題点を有していた。特に汚水を流すために弁体を開けている状態のときに汚物タンクへ高圧が掛かると、汚水が逆流しやすい欠点があった。   Due to this pressure, if there is only one valve body as in the prior art 1, when a high pressure is applied to the waste tank due to traveling in the tunnel, the waste water in the waste water pipe is installed in the low pressure vehicle. In other words, there was a problem that the urinal may flow back to the urinal. In particular, when high pressure is applied to the filth tank when the valve body is opened in order to flow the sewage, the sewage tends to flow backward.

また、従来技術２では、中間タンクや、その加圧減圧を行うための各種付属部品が必要なため、それらを設置する場所や価格が高くなってしまう課題や、強制的に汚水を吸引するため、汚水とともに空気を吸引してしまい、そのときの空気摩擦による騒音が高い頻度で発生してしまう課題があった。   Moreover, in the prior art 2, since an intermediate tank and various accessory parts for performing the pressurization and decompression are necessary, a problem that the place and cost for installing them are increased, and sewage is forcibly sucked in. There is a problem that air is sucked together with sewage, and noise due to air friction at that time is frequently generated.

この発明に係る車両用汚水処理装置は、  The sewage treatment apparatus for vehicles according to this invention is

Odor-containing air is deodorized by the deodorizing device and is discharged into the vehicle through the air vent valve. It is characterized by that.

この発明によれば、圧力が常圧にほぼ調整されている車内に設置された汚水受器と、車外にある汚物タンクとの間に少なくとも２つの弁を設けて、その中間に空気抜き弁を設けるとともに、２つの弁のどちらかが必ず閉鎖しているため、汚水管に車外から圧力が掛かっても、空気抜き弁から空気を排気することにより、汚物タンクからの汚水管を経由して汚水受器に伝わる圧力を防止することができる。特に上流側開閉弁が車内部分に設置され、下流側開閉弁が車外部分に設置される車両内に設けられる車両用汚水処理装置であると、車両外部からの圧力は車内の汚水受器まで達することはない。 According to the present invention, at least two valves are provided between a sewage receiver installed in a vehicle whose pressure is substantially adjusted to normal pressure and a filth tank outside the vehicle, and an air vent valve is provided between them. together, since the one of two valves is always closed, even under pressure from outside the sewage pipe, by evacuating air from the air disconnect can valve, via a sewage pipe from dirt tank sewage it is possible to prevent the pressure transmitted to the receiver. In particular, in the case of a vehicle sewage treatment device provided in a vehicle in which the upstream side opening / closing valve is installed in the vehicle interior and the downstream side opening / closing valve is installed in the vehicle exterior portion, the pressure from the outside of the vehicle reaches the sewage receiver in the vehicle There is nothing.

また、空気抜き弁近傍に、又は空気抜き弁を有する配管に消臭装置を設けることにより、車内へ排気される空気の脱臭を行うことにより不快な臭気を防止している。   Further, by providing a deodorizing device in the vicinity of the air vent valve or in a pipe having the air vent valve, unpleasant odor is prevented by deodorizing the air exhausted into the vehicle.

次に、この発明の車両用汚水処理装置について１つの実施形態を示す図１及び図２に基づいて説明する。車両用汚水処理装置は、車両内に設けられる小便器である汚水受器１と、汚水管２と、汚物タンク３と、排気用配管４と、上流側開閉弁５と、下流側開閉弁６と、コントロールユニット（制御部）７、洗浄スイッチ８を有する。９は車内と車外を区分する部分であり、実施形態では車内床部分である。   Next, the sewage treatment apparatus for vehicles according to the present invention will be described with reference to FIGS. 1 and 2 showing one embodiment. The sewage treatment apparatus for vehicles includes a sewage receiver 1 which is a urinal provided in a vehicle, a sewage pipe 2, a filth tank 3, an exhaust pipe 4, an upstream on-off valve 5, and a downstream on-off valve 6.

汚水受器１は、この実施形態では小児用小便器であるが大人用小便器でもよい。汚水受器１は、上部に開閉自在の給水管７０を設けている。給水管７０は、その上流で給水タンク７１に接続しており、電磁開閉弁である洗浄弁７２が適宜の状態で開閉して汚水受器１に送水し汚水受器１を洗浄する。コントロールユニット７は、予め入力されたプログラムによって洗浄弁７２、洗浄スイッチ８、上流側開閉弁５、下流側開閉弁６に検知信号の受信や指示信号の送信を行う。洗浄スイッチ８は光電センサー或いは押しボタンスイッチ等からなる。   The sewage receiver 1 is a urinal for children in this embodiment, but may be a urinal for adults. The sewage receiver 1 is provided with a water supply pipe 70 that can be freely opened and closed at the top. The water supply pipe 70 is connected to a water supply tank 71 upstream thereof, and a cleaning valve 72 that is an electromagnetic on-off valve opens and closes in an appropriate state to supply water to the sewage receiver 1 and clean the sewage receiver 1. The control unit 7 receives a detection signal and transmits an instruction signal to the cleaning valve 72, the cleaning switch 8, the upstream opening / closing valve 5, and the downstream opening / closing valve 6 according to a program inputted in advance. The cleaning switch 8 includes a photoelectric sensor or a push button switch.

汚水管２は、この実施例では上部汚水管２０と、中間部汚水管２１と、下部汚水管２２とを直列に接続してなり、上部汚水管２０は上流側端部で汚水受器１に接続し、下部汚水管２２は下流側端部で汚物タンク３に接続している。上部汚水管２０と中間部汚水管２１との間で、かつ車内部分に上流側開閉弁５を設けており、中間部汚水管２１と下部汚水管２２との間で、かつ車外部分に下流側開閉弁６を設けている。   In this embodiment, the sewage pipe 2 is formed by connecting an upper sewage pipe 20, an intermediate sewage pipe 21, and a lower sewage pipe 22 in series, and the upper sewage pipe 20 is connected to the sewage receiver 1 at the upstream end. The lower sewage pipe 22 is connected to the filth tank 3 at the downstream end. An upstream opening / closing valve 5 is provided between the upper sewage pipe 20 and the intermediate sewage pipe 21 and in the vehicle interior part, and between the intermediate sewage pipe 21 and the lower sewage pipe 22 and downstream in the vehicle outer part. An on-off valve 6 is provided.

汚水管２の他の実施例では、１本の汚水管の上端部、すなわち汚水管２と汚水受器１との接続部でかつ車内部分に上流側開閉弁５を設けてもよく、１本の汚水管２の下端部、すなわち汚水管２と汚物タンク３との接続部で、かつ車外部分に下流側開閉弁６を設けてもよい。この実施例では、後述する排気用配管４は、１本の汚水管２の中間部で車内部分となる位置に管途中から分岐するように設けている   In another embodiment of the sewage pipe 2, the upstream side opening / closing valve 5 may be provided at the upper end of one sewage pipe, that is, at the connection between the sewage pipe 2 and the sewage receiver 1 and in the interior of the vehicle. A downstream opening / closing valve 6 may be provided at the lower end of the sewage pipe 2, that is, at the connection part between the sewage pipe 2 and the filth tank 3 and on the outside of the vehicle. In this embodiment, an exhaust pipe 4 to be described later is provided so as to branch from the middle of the pipe to a position that becomes an in-vehicle portion at the middle part of one sewage pipe 2.

上流側開閉弁５及び下流側開閉弁６は、この実施例では電磁式エアスライドバルブとからなるスライド式開閉弁であるが、管路を開閉する弁であればボール弁等の他の開閉弁で構成してもよい。７３はエアタンクであり、エアスライドバルブへエアを供給している。そして、上流側開閉弁５と下流側開閉弁６は、少なくとも互いの開口状態が同時には起こらないようにコントロールユニット７によって制御している。すなわち、上流側開閉弁５が開口状態のときは、下流側開閉弁６は閉鎖状態であり、下流側開閉弁６が開口状態のときには上流側開閉弁５が閉鎖状態である。 The upstream side open / close valve 5 and the downstream side open / close valve 6 are slide type open / close valves comprising an electromagnetic air slide valve in this embodiment. You may comprise. 73 is an air tank which supplies air to the air slide valve. The upstream opening / closing valve 5 and the downstream opening / closing valve 6 are controlled by the control unit 7 so that at least the mutual opening state does not occur at the same time. That is, when the upstream opening / closing valve 5 is open, the downstream opening / closing valve 6 is closed, and when the downstream opening / closing valve 6 is open, the upstream opening / closing valve 5 is closed.

中間部汚水管２１は、管途中から分岐する排気用配管４を車内部分となる位置に設けている。排気用配管４は、端部を車内に開口させ、その開口に空気抜き弁（エア抜きバルブ）４０を設けており、空気抜き弁４０の外側、又は内側、又は排気用配管４内に消臭装置４１を設けている。   The intermediate part sewage pipe 21 is provided with an exhaust pipe 4 that branches off from the middle of the pipe at a position that becomes an in-vehicle portion. An end of the exhaust pipe 4 is opened in the vehicle, and an air vent valve (air vent valve) 40 is provided in the opening, and a deodorizing device 41 is provided outside or inside the air vent valve 40 or inside the exhaust pipe 4. Is provided.

汚物タンク３は、各汚水管２や図示しない汚物管等の下流側に接続され各汚水、汚物を列車、電車使用中、貯留する装置である。汚物タンク３は、車体の底部９の下方の車外に配設され、車内の圧力調整を受けない。   The filth tank 3 is a device that is connected to the downstream side of each sewage pipe 2 or a filth pipe (not shown) and stores the sewage and filth while the train or train is in use. The filth tank 3 is disposed outside the vehicle below the bottom 9 of the vehicle body and is not subjected to pressure adjustment inside the vehicle.

次に、この発明の実施形態の車両用汚水処理装置の作用について図２の作動タイムチャートに基づき説明する。車内において、使用者の使用が無い状態では、コントロールユニット７からの指示で、上流側開閉弁５も下流側開閉弁６も閉鎖した状態である。この状態で車両がトンネル内に入っても、下流側開閉弁６によって管内の加圧は、そこで止り、それより上流部へ波及しない。   Next, the operation of the sewage treatment apparatus for vehicles according to the embodiment of the present invention will be described based on the operation time chart of FIG. In a state where the user does not use the vehicle, the upstream side open / close valve 5 and the downstream side open / close valve 6 are closed by an instruction from the control unit 7. Even if the vehicle enters the tunnel in this state, the pressurization in the pipe is stopped there by the downstream opening / closing valve 6 and does not spread to the upstream part.

次に使用者が小用をした後、洗浄スイッチ８によりコントロールユニット７へ信号が送られる。コントロールユニット７から洗浄弁７２及び上流側開閉弁５へ信号が送られ洗浄弁７２が開口して汚水受器１へ送水し洗浄すると同時に上流側開閉弁５も開口する。この実施例では洗浄弁７２の開口時間及び上流側開閉弁５の開口時間は数秒程度であり、時間経過後各開閉弁７２、５は閉鎖する。 Next, after the user makes a small use, a signal is sent to the control unit 7 by the cleaning switch 8. Upstream side switching valve 5 and at the same time water washing to the sewage receptacle 1 by flush valve 72 and the upstream side switching valve 5 signal is sent to the flush valve 72 is opened from the control unit 7 is also opened. In this embodiment, the opening time of the cleaning valve 72 and the opening time of the upstream side opening / closing valve 5 are about several seconds, and the opening / closing valves 72 and 5 are closed after the elapse of time.

洗浄スイッチ８は、光電センサーである場合は自動的に使用者が小用後汚水受器１から離れたことを検知してコントロールユニット７に検知信号を送る。また、洗浄スイッチ８が、押しボタンスイッチである場合は、使用後の使用者の押しボタンの押圧により洗浄弁７２と上流側開閉弁５を開口させる信号がコントロールユニット７へ送られる。汚水は、重力により上部汚水管２０から中間部汚水管２１を落下して流れ、下流側開閉弁６まで行って、そこで止められ一瞬溜まる。   When the washing switch 8 is a photoelectric sensor, it automatically detects that the user has left the sewage receiver 1 after the small use and sends a detection signal to the control unit 7. When the cleaning switch 8 is a push button switch, a signal for opening the cleaning valve 72 and the upstream side open / close valve 5 is sent to the control unit 7 by pressing the push button of the user after use. The sewage flows from the upper sewage pipe 20 through the middle sewage pipe 21 by gravity and flows to the downstream opening / closing valve 6 where it is stopped and collected for a moment.

次に、上流側開閉弁５が時間の経過後自動的に閉鎖し、その閉鎖の数秒後に閉鎖していた下流側開閉弁６が開口する。このプログラムは、予め設定されてコントロールユニット７に入力されている。下流側開閉弁６はコントロールユニット７からの指示で数秒後に閉鎖される。上流側開閉弁５を閉鎖させた状態で下流側開閉弁６を開口させて汚水を下部汚水管２２から汚物タンク３へ落下させる。   Next, the upstream side open / close valve 5 is automatically closed after a lapse of time, and the downstream side open / close valve 6 which has been closed several seconds after the closing is opened. This program is set in advance and input to the control unit 7. The downstream on-off valve 6 is closed after a few seconds in response to an instruction from the control unit 7. With the upstream side opening / closing valve 5 closed, the downstream side opening / closing valve 6 is opened, and the sewage is dropped from the lower sewage pipe 22 to the waste tank 3.

この状態は、使用者の使用前の状態（００２２欄参照）となり、順次使用者の使用により汚水は順次、上述の作用を繰り返す。これらの作動は、予めコントロールユニット７に入力したプログラムに従って自動的に行われる。   This state is the state before use by the user (see column 0022), and the sewage sequentially repeats the above-described action as the user sequentially uses it. These operations are automatically performed according to a program previously input to the control unit 7.

したがって、下流側開閉弁６が開口した状態で車両がトンネル内に入り汚物タンク３に圧力が掛かった場合でも、上流側開閉弁５の閉鎖によって管内の加圧はそこで止り、それより上流部へ波及しない。そのため、汚水が汚水受器１内まで逆流することがない。また上流側開閉弁５が開口した状態で車両がトンネル内に入っても、下流側開閉弁６が閉鎖しているので管内の加圧は、そこで止り、それより上流部へ波及しない。   Therefore, even when the vehicle enters the tunnel and the filth tank 3 is pressurized with the downstream side opening / closing valve 6 open, the pressure in the pipe is stopped there by closing the upstream side opening / closing valve 5, and further to the upstream side. It doesn't spread. Therefore, sewage does not flow back into the sewage receiver 1. Even if the vehicle enters the tunnel with the upstream side opening / closing valve 5 open, the downstream side opening / closing valve 6 is closed, so that the pressurization in the pipe stops there and does not reach the upstream part.

また、上流側開閉弁５と下流側開閉弁６との間で、かつ開口が車内部分に配置された空気抜き弁４０を設けているため、下流側開閉弁６に汚水が溜まった状態で発生する臭気を含む空気は、排気用配管４から空気抜き弁４０を通して車内へ排気されるが、このとき消臭装置４１を通るため臭気は抜かされる。また排気用配管４の開口部分が車内であるため外部から圧力は受けない。 Further, since the air vent valve 40 is provided between the upstream side open / close valve 5 and the downstream side open / close valve 6 and the opening is disposed in the interior of the vehicle, this occurs in a state where sewage is accumulated in the downstream side open / close valve 6. air containing odor, but is exhausted from the exhaust pipe 4 into the vehicle through the air disconnect came valve 40, the odor because through the deodorizing device 41 this time is missed. Further, since the opening of the exhaust pipe 4 is inside the vehicle, no pressure is received from the outside.

この発明は、電車、列車、特に新幹線（登録商標）車両や長距離用の電車、列車内に設置され利用される可能性が高い。特に汚水を重力で落下する方式の小児用小便器について実用性が高い。 The present invention is highly likely to be installed and used in trains, trains, in particular, Shinkansen (registered trademark) vehicles, long-distance trains, and trains. Particularly useful for urinals for children that drop sewage by gravity.
