Description

この発明は、真空排水システムに関し、特にたとえば、建物内から出る排水を公共下水などへ排出する、真空排水システムに関する。   The present invention relates to a vacuum drainage system, and more particularly to a vacuum drainage system that discharges drainage from a building to public sewage.

従来、建物内から排出される排水は自然流下方式で集水されていたが、自然流下方式では空調ダクトや梁などを回避することができない場合があるため、この問題を解決するシステムとして真空排水システムが用いられている。   Conventionally, wastewater discharged from buildings has been collected by the natural flow method, but airflow ducts and beams may not be avoided by the natural flow method, so vacuum drainage is a system that solves this problem. The system is used.

この真空排水システムの一例が、特許文献１に開示されている。この特許文献１の真空排水設備では、排水発生器具の近傍に設けた真空弁が開くと、排水発生器具内の排水と空気との混合物は急激に横管内に流れ込み、気液分離装置で空気と排水とに分離されて、空気および排水は別の立て管に流入する。   An example of this vacuum drainage system is disclosed in Patent Document 1. In the vacuum drainage facility of Patent Document 1, when a vacuum valve provided in the vicinity of the drainage generator is opened, a mixture of wastewater and air in the drainage generator suddenly flows into the horizontal pipe and is separated from the air by the gas-liquid separator. Separated into drainage, air and drainage flow into separate standpipe.

また、他の真空排水システムの一例が、特許文献２に開示されている。特許文献２の真空排水収集システムでは、排水の逆流を防止するため、天井裏を這い回す真空配管に排水逆流防止用逆止弁を取り付け、真空配管の水道管などを回避するための上越し部に逆止弁を設ける。
特開平６−１０８５２１号 特開２００２−２２７２６７号 Another example of the vacuum drainage system is disclosed in Patent Document 2. In the vacuum drainage collection system of Patent Document 2, in order to prevent the backflow of drainage, a check valve for preventing backflow of drainage is attached to the vacuum pipe that crawls the back of the ceiling, and the upper part for avoiding the water pipe of the vacuum pipe, etc. Provide a check valve.
JP-A-6-108521 JP 2002-227267 A

特許文献１の従来技術では、排水発生器具から排水とともに空気が吸引されるため、大きな音が発生してしまう。   In the prior art of Patent Document 1, since air is sucked together with drainage from the drainage generator, a loud noise is generated.

特許文献２の従来技術では、真空配管の上越し部に逆止弁を配置できない場合があり、自由な配管ができない。   In the prior art of Patent Document 2, there is a case where a check valve cannot be disposed in the upper portion of the vacuum pipe, and thus free piping cannot be performed.

また、１つの集水タンクでは、集水タンク内の排水を排出している間は汚水ます内の排水を集水タンクへ吸引することができない。   Further, in one water collection tank, the waste water in the sewage can not be sucked into the water collection tank while the waste water in the water collection tank is discharged.

それゆえに、この発明の主たる目的は、排水騒音を低減することができる、真空排水システムを提供することである。   Therefore, a main object of the present invention is to provide a vacuum drainage system that can reduce drainage noise.

この発明の他の目的は、吸引管を自由に配管できる、真空排水システムを提供することである。   Another object of the present invention is to provide a vacuum drainage system capable of freely piping a suction pipe.

この発明のさらに他の目的は、集水タンクを常に集排水することができる、真空排水システムを提供することである。   Still another object of the present invention is to provide a vacuum drainage system that can always collect and drain a water collection tank.

請求項１の発明は、排水を貯留する検知枡、検知枡から排水を集水タンクに真空吸引する吸引管、吸引管に設けられる真空弁、真空弁開成信号に応じて真空弁を開く真空弁開成手段、および吸引管が検知枡内の空気を吸引し始める前に真空弁を閉じる真空弁閉成手段を備える、真空排水システムである。   The invention of claim 1 is a detection rod for storing drainage, a suction pipe for vacuum suctioning drainage from the detection rod to a water collection tank, a vacuum valve provided in the suction pipe, and a vacuum valve for opening a vacuum valve in response to a vacuum valve opening signal A vacuum drainage system comprising opening means and vacuum valve closing means for closing the vacuum valve before the suction pipe begins to suck air in the detection tank.

請求項１の発明では、検知枡内に排水を貯留し、その排水の水位が上昇すると、真空弁開成信号が発せられ、その真空弁開成信号に応じて真空弁開成手段は真空弁を開いて、吸引管は検知枡内の排水を吸引する。そして、吸引管が検知枡内の排水を吸引し始めてから、空気を吸い込む前に、真空閉成手段は真空弁を閉じる。   In the first aspect of the present invention, when drainage is stored in the detection tank and the water level of the drainage rises, a vacuum valve opening signal is issued, and the vacuum valve opening means opens the vacuum valve in response to the vacuum valve opening signal. The suction pipe sucks the waste water in the detection tank. The vacuum closing means closes the vacuum valve before the air is sucked after the suction pipe starts to suck the waste water in the detection tank.

このように、吸引管が空気まで吸い込むまでに吸引を止めることにより、吸引管は検知枡内の排水のみを吸引するため、空気が排水と共に吸引される際に生じる騒音を抑制することができる。   In this way, by stopping the suction before the suction pipe sucks up to the air, the suction pipe sucks only the waste water in the detection tub, so that noise generated when the air is sucked together with the waste water can be suppressed.

請求項２の発明は、排水を貯留する検知枡、検知枡から排水を集水タンクに真空吸引する吸引管、吸引管に設けられる真空弁、真空弁と集水タンクとの間における最も高い位置で吸引管に設けられる真空取出口、真空取出口を真空弁と接続する真空管、真空弁開成信号に応じて真空弁を開く真空弁開成手段、および真空弁を閉成する真空弁閉成手段を備える、真空排水システムである。   The invention according to claim 2 is a detection rod for storing drainage, a suction pipe for vacuum suctioning the drainage from the detection rod to the water collection tank, a vacuum valve provided in the suction pipe, and the highest position between the vacuum valve and the water collection tank A vacuum outlet provided in the suction pipe, a vacuum pipe connecting the vacuum outlet to the vacuum valve, a vacuum valve opening means for opening the vacuum valve in response to a vacuum valve opening signal, and a vacuum valve closing means for closing the vacuum valve A vacuum drainage system is provided.

請求項２の発明では、検知枡内に排水を貯留し、その排水の水位が上昇すると、真空弁開成信号が発せられ、その真空弁開成信号に応じて真空弁開成手段は真空弁を開く。そして、吸引管は検知枡内の排水を真空吸引した後、真空閉成手段は真空弁を閉じる。   In the invention of claim 2, when the waste water is stored in the detection tank and the water level of the waste water rises, a vacuum valve opening signal is issued, and the vacuum valve opening means opens the vacuum valve in response to the vacuum valve opening signal. And after a suction pipe vacuum-sucks the waste_water | drain in a detection tub, a vacuum closing means closes a vacuum valve.

真空弁を開放している間だけ、検知枡内の排水は吸引管に真空吸引され、吸引管内を移動して、集水タンクへ流入する。真空弁を閉じれば、吸引管内の排水の一部は自然流下して流れ落ち、その他の排水は吸引管内に残る。そして、再び真空弁を開放すると、吸引管内の排水は集水タンクの方へ移動し始める。このため、吸引管の中は排水に満たされており、真空取出口を最も高い位置に設けなければ、吸引管内の排水は真空取出口から流れ落ちて真空電磁弁に流入してしまう恐れがある。しかし、吸引管の最も高い位置では、排水は自然流下して流れ落ちて真空状態が保たれるため、真空取出口を最も高い位置に設け、真空取出口の上面に設けた開口に真空管の一端を繋ぎ、この真空管の他端を真空弁に接続すると、排水は真空管内に流入せず、真空取出口および真空弁を結ぶ真空管内は真空状態となる。したがって、真空弁開成手段は真空取出口から得た真空を制御して、真空弁を開閉することができる。   Only while the vacuum valve is open, the waste water in the detection tank is vacuumed into the suction pipe, moves through the suction pipe, and flows into the water collection tank. When the vacuum valve is closed, a part of the drainage in the suction pipe flows down and flows down, and the other drainage remains in the suction pipe. When the vacuum valve is opened again, the waste water in the suction pipe starts to move toward the water collection tank. For this reason, the inside of the suction pipe is filled with drainage, and if the vacuum outlet is not provided at the highest position, the drainage in the suction pipe may flow down from the vacuum outlet and flow into the vacuum solenoid valve. However, at the highest position of the suction pipe, the drainage flows down and flows down to maintain the vacuum state, so the vacuum outlet is provided at the highest position, and one end of the vacuum pipe is connected to the opening provided on the upper surface of the vacuum outlet. When the other end of the vacuum tube is connected to the vacuum valve, the drainage does not flow into the vacuum tube, and the vacuum tube connecting the vacuum outlet and the vacuum valve is in a vacuum state. Therefore, the vacuum valve opening means can open and close the vacuum valve by controlling the vacuum obtained from the vacuum outlet.

請求項３の発明は、真空開成手段は検知枡内に所定量以上の排水が貯まったことを検知する増水水位センサを含み、増水水位センサからの信号である真空弁開成信号に応じて真空弁を開き、真空弁閉成手段は真空弁開成信号に応答してトリガされるタイマを含み、タイマのタイムアップに応答して真空弁を閉じる、請求項１または２記載の真空排水システムである。   According to a third aspect of the present invention, the vacuum opening means includes an increased water level sensor that detects that a predetermined amount or more of waste water has accumulated in the detection tank, and the vacuum valve is activated in response to a vacuum valve opening signal that is a signal from the increased water level sensor. The vacuum drainage system according to claim 1 or 2, wherein the vacuum valve closing means includes a timer triggered in response to a vacuum valve opening signal, and closes the vacuum valve in response to the timer time-up.

請求項３の発明では、増水水位センサを設けた検知枡内に排水が流入し、検知枡内の排水水位が増水水位センサの位置まで上昇すると、増水水位センサはこれを検知して、タイマを作動させるとともに、真空弁開成手段は真空弁を開く。真空弁が開かれると、吸引管は検知枡内の排水を真空吸引する。そして、タイマがタイムアップすると、真空閉成手段は真空弁を閉じる。   In the invention of claim 3, when the drainage flows into the detection tank provided with the increased water level sensor and the drainage water level in the detection tank rises to the position of the increased water level sensor, the increased water level sensor detects this and sets the timer. In operation, the vacuum valve opening means opens the vacuum valve. When the vacuum valve is opened, the suction pipe vacuums the drainage in the detection tank. When the timer expires, the vacuum closing means closes the vacuum valve.

このタイマを吸引管が検知枡内の排水を吸引し始めてから、空気を吸い込むまでの時間に予め設定しておけば、吸引管は検知枡内の排水のみを吸引する。   If this timer is set in advance to a time from when the suction pipe starts sucking the waste water in the detection tank until the air is sucked in, the suction pipe sucks only the waste water in the detection tank.

このように、タイマによれば、設定時間を変更することにより吸引管の吸引量を簡単に調整することができるため、この真空排水システムをどのような大きさの検知枡にも対応させることができる。   Thus, according to the timer, it is possible to easily adjust the suction amount of the suction pipe by changing the set time, so that this vacuum drainage system can be adapted to any size detection rod. it can.

請求項４の発明は、真空開成手段は検知枡内に所定量以上の排水が貯まったことを検知する増水水位センサを含み、増水水位センサからの信号である真空弁開成信号に応じて真空弁を開き、真空弁閉成手段は、検知枡内の排水量が所定以下になったことを検知する減水水位センサを含み、減水水位センサからの信号に応答して真空弁を閉じる、請求項１または２記載の真空排水システムである。   According to a fourth aspect of the present invention, the vacuum opening means includes an increased water level sensor that detects that a predetermined amount or more of waste water has accumulated in the detection tank, and the vacuum valve is activated in response to a vacuum valve opening signal that is a signal from the increased water level sensor. The vacuum valve closing means includes a reduced water level sensor that detects that the amount of drainage in the detection tank has become a predetermined value or less, and closes the vacuum valve in response to a signal from the reduced water level sensor. 2. The vacuum drainage system according to 2.

請求項４の発明では、検知枡の側壁の下側に吸引管を接続し、検知枡内に増水水位センサおよび減水水位センサを据え、増水水位センサを排水の流入口より下方に配置し、減水水位センサを増水水位センサより下で、吸引管の接続口より少し上に配置する。   In the invention of claim 4, a suction pipe is connected to the lower side of the side wall of the detection rod, a water level increase sensor and a water decrease level sensor are installed in the detection rod, and the water increase level sensor is arranged below the inflow port of the waste water. Place the water level sensor below the water level sensor and slightly above the inlet of the suction pipe.

このような検知枡に排水が流入し、排水水位が増水水位センサの位置に達すると、増水水位センサからの信号により真空弁開成手段は真空弁を開く。そして、検知枡内の排水は吸引管に真空吸引されて、検知枡内の排水水位が低下して減水水位センサの位置まで下がると、減水水位センサからの信号に応じて真空弁閉成手段は真空弁を閉じる。   When drainage flows into such a detection tank and the drainage water level reaches the position of the increased water level sensor, the vacuum valve opening means opens the vacuum valve by a signal from the increased water level sensor. Then, when the drainage water in the detection tank is vacuumed into the suction pipe, and the drainage water level in the detection tank drops to the position of the reduced water level sensor, the vacuum valve closing means is activated according to the signal from the reduced water level sensor. Close the vacuum valve.

このように、検知枡内の排水水位が減水水位センサの位置、すなわち吸引管の接続口より上の位置に達したとき、吸引管を閉じると、検知枡内に排水はまだ残っており、この排水により吸引管の接続口は浸されているため、吸引管は空気を吸い込まず、吸引管が排水と共に空気を吸引する際に生じる吸引音を抑制することができる。   In this way, when the drainage water level in the detection tank reaches the position of the reduced water level sensor, i.e., the position above the connection port of the suction pipe, if the suction pipe is closed, drainage still remains in the detection bowl. Since the connection port of the suction pipe is immersed in the drainage, the suction pipe does not suck in air, and the suction sound generated when the suction pipe sucks air together with the drainage can be suppressed.

請求項５の発明は、便器に設けられる排水スイッチ、便器から排水を集水タンクに真空吸引する吸引管、吸引管に設けられる真空弁、真空弁開成信号に応じて真空弁を開く真空弁開成手段、および吸引管が便器内の空気を吸引し始める前に真空弁を閉じる真空弁閉成手段を備える、真空排水システムである。   According to a fifth aspect of the present invention, there is provided a drain switch provided in the toilet bowl, a suction pipe for vacuum suction of waste water from the toilet bowl into a water collection tank, a vacuum valve provided in the suction pipe, and a vacuum valve opening that opens the vacuum valve in response to a vacuum valve opening signal A vacuum drainage system comprising means and vacuum valve closing means for closing the vacuum valve before the suction tube begins to suck air in the toilet bowl.

請求項５の発明では、真空弁開成信号が発せられると、真空弁は開いて、吸引管は便器内の排水を真空吸引する。そして、吸引管が便器内の空気を吸引し始める前に、真空弁閉成手段真空弁を閉じる。   In the invention of claim 5, when a vacuum valve opening signal is issued, the vacuum valve is opened and the suction pipe vacuums the waste water in the toilet. And before a suction pipe begins to attract | suck the air in a toilet bowl, a vacuum valve closing means vacuum valve is closed.

このように、吸引管は排水のみを吸引することにより、空気が排水と共に吸引される際の騒音を抑えることができる。   In this way, the suction pipe sucks only the waste water, so that noise when air is sucked together with the waste water can be suppressed.

請求項６の発明は、便器に設けられる排水スイッチ、便器から排水を集水タンクに真空吸引する吸引管、吸引管に設けられる真空弁、真空弁と集水タンクとの間における最も高い位置で吸引管に設けられる真空取出口、真空取出口を真空弁と接続する真空管、真空弁開成信号に応じて真空弁を開く真空弁開成手段、および真空弁を閉成する真空弁閉成手段を備える、真空排水システムである。   The invention of claim 6 is a drain switch provided in the toilet bowl, a suction pipe for vacuum suction of waste water from the toilet bowl to the water collection tank, a vacuum valve provided in the suction pipe, and the highest position between the vacuum valve and the water collection tank. A vacuum outlet provided in the suction pipe, a vacuum pipe connecting the vacuum outlet to the vacuum valve, a vacuum valve opening means for opening the vacuum valve in response to a vacuum valve opening signal, and a vacuum valve closing means for closing the vacuum valve A vacuum drainage system.

請求項６の発明では、便器と集水タンクとを吸引管で結び、吸引管の途中に真空弁を設ける。この真空弁と集水タンクとの間における吸引管の最も高い位置に真空取出口を設け、真空取出口を真空管で真空弁と接続させる。   In the invention of claim 6, the toilet bowl and the water collecting tank are connected by a suction pipe, and a vacuum valve is provided in the middle of the suction pipe. A vacuum outlet is provided at the highest position of the suction pipe between the vacuum valve and the water collection tank, and the vacuum outlet is connected to the vacuum valve by a vacuum pipe.

このような真空排水システムにおいて、真空弁開成信号が発せられると、その真空弁開成信号に応じて真空弁開成手段は真空弁を開いて、吸引管は便器内の排水を真空吸引する。そして、排水が吸引された後、真空閉成手段は真空弁を閉じる。   In such a vacuum drainage system, when a vacuum valve opening signal is issued, the vacuum valve opening means opens the vacuum valve in response to the vacuum valve opening signal, and the suction pipe vacuums the drainage in the toilet. And after drainage is attracted | sucked, a vacuum closing means closes a vacuum valve.

この吸引管の中は排水に満たされる場合があるが、真空取出口を最も高い位置に設けるため、真空取出口の排水は自然流下して流れ落ちて真空取出口は真空状態となり、吸引管内の排水は真空取出口および真空弁を結ぶ真空管内に流入しない。したがって、真空弁開成手段は真空取出口から真空管を通して真空を得て、この真空により真空弁を開閉することができる。   The suction pipe may be filled with drainage, but since the vacuum outlet is provided at the highest position, the vacuum outlet drains down and flows down naturally, and the vacuum outlet is in a vacuum state. Does not flow into the vacuum tube connecting the vacuum outlet and the vacuum valve. Therefore, the vacuum valve opening means can obtain a vacuum through the vacuum tube from the vacuum outlet, and can open and close the vacuum valve by this vacuum.

請求項７の発明は、真空弁開成手段は排水スイッチを含み、排水スイッチからの信号である真空弁開成信号に応じて真空弁を開き、真空弁閉成手段は、真空弁開成信号からの信号に応答してトリガされるタイマを含み、タイマのタイムアップに応答して真空弁を閉じる、請求項５または６記載の真空排水システムである。   In the invention of claim 7, the vacuum valve opening means includes a drain switch, and opens the vacuum valve in response to a vacuum valve opening signal which is a signal from the drain switch. The vacuum valve closing means is a signal from the vacuum valve opening signal. 7. A vacuum drainage system according to claim 5 or 6 including a timer triggered in response to closing the vacuum valve in response to timer expiration.

請求項７の発明では、吸引管が便器内の排水を真空吸引し始めてから空気を吸い込むまでの時間をタイマに予め設定しておく。そして、排水スイッチを押すと真空弁開成手段は真空弁を開き、吸引管は便器内の排水を真空吸引する。便器内の排水水位は低下し、吸引管が空気を吸い込むまでに、タイマの設定時間は経過して、真空弁閉成手段は真空弁を閉じる。   According to the seventh aspect of the present invention, the time from when the suction pipe starts to suck the waste water in the toilet in vacuum until the air is sucked is set in advance in the timer. When the drain switch is pressed, the vacuum valve opening means opens the vacuum valve, and the suction pipe vacuums the waste water in the toilet. The drainage water level in the toilet bowl decreases, the time set by the timer elapses until the suction pipe sucks air, and the vacuum valve closing means closes the vacuum valve.

このように、吸引管は排水のみを吸引することにより、空気が排水と共に吸引される際の騒音を抑えることができる。   In this way, the suction pipe sucks only the waste water, so that noise when air is sucked together with the waste water can be suppressed.

また、タイマにより吸引時間、すなわち排水の吸引量を調整することにより、このような真空排水便器をさまざまなタイプの便器に適応させることができる。   In addition, by adjusting the suction time, that is, the suction amount of the waste water by the timer, such a vacuum drainage toilet can be adapted to various types of toilets.

請求項８の発明は、吸引管は真空取出口から集水タンクに至るまでの間で構造物の形状に合わせて上下して配管される部分を含むことを特徴とする、請求項２または６記載の真空排水システムである。   The invention according to claim 8 is characterized in that the suction pipe includes a portion that is vertically arranged according to the shape of the structure between the vacuum outlet and the water collection tank. The vacuum drainage system described.

請求項８の発明では、真空取出口と集水タンクとの間で吸引管が上下しても、真空弁と集水タンクとの間における吸引管の最も高い位置に真空取出口を設けることにより、真空弁と真空取出口とを繋ぐ真空管は真空状態となり、真空開閉手段はこの真空管からの真空を制御して真空弁を開閉することができる。   In the invention of claim 8, by providing the vacuum outlet at the highest position of the suction pipe between the vacuum valve and the water collection tank even if the suction pipe moves up and down between the vacuum outlet and the water collection tank. The vacuum tube connecting the vacuum valve and the vacuum outlet is in a vacuum state, and the vacuum opening / closing means can open and close the vacuum valve by controlling the vacuum from the vacuum tube.

請求項９の発明は、排水を吸引する真空ポンプ、排水源からの排水を真空吸引する吸引管、吸引管に接続する２台の集水タンク、集水タンクからの排水を排出する排水本管を具備する真空排水システムにおいて、さらに、各集水タンクを吸引管に接続するタンク切替弁、各集水タンクを排水本管に接続する排水切替弁、各集水タンクを真空ポンプに接続する真空管ポンプ切替弁、および各集水タンクを大気開放する大気開放弁を備え、一方の集水タンクのタンク切替弁および真空ポンプ切替弁を閉じ、かつ排水切替弁および大気開放弁を開いた状態で、他方の集水タンクのタンク切替弁および真空ポンプ切替弁を開き、かつ排水切替弁および大気開放弁を閉じることにより、一方の集水タンクに排水源から排水を集水しながら、他方の集水タンクから集水タンク内の排水を排水本管へ排出する、真空排水システムである。   The invention of claim 9 is a vacuum pump for sucking waste water, a suction pipe for vacuum suction of waste water from a drain source, two water collection tanks connected to the suction pipe, and a drain main for discharging waste water from the water collection tank In addition, a tank switching valve for connecting each water collection tank to a suction pipe, a drain switching valve for connecting each water collection tank to a main drain, and a vacuum pipe for connecting each water collection tank to a vacuum pump With a pump switching valve and an air release valve that opens each water collection tank to the atmosphere, with the tank switching valve and vacuum pump switching valve of one water collection tank closed, and with the drainage switching valve and air release valve open, Open the tank switching valve and vacuum pump switching valve of the other water collection tank and close the drainage switching valve and the air release valve to collect the wastewater from the drainage source in one water collection tank and collect the other water collection T Discharging the waste water in the collection tank to the waste water mains by click, a vacuum drainage system.

請求項９の発明では、２台の集水タンクの内の一方、たとえば第１集水タンクの大気開放弁および排水用弁を閉じた状態で真空ポンプ切替用弁およびタンク切替用弁を開くと、第１集水タンク内は真空ポンプにより一定の真空圧に減圧され、第１集水タンクに接続する吸引管も一定の真空圧に減圧されて、吸引管は検知枡内の排水を真空吸引し、第１集水タンク内に流入させる。また、他方の集水タンク、たとえば第２集水タンクの真空ポンプ切替用弁およびタンク切替用弁を閉めた状態で、第２集水タンクの大気開放弁を開けば、大気開放弁から第２集水タンク内に空気が吸い込まれ、第２集水タンク内は大気圧になる。この状態で排水用弁を開くと、第２集水タンク内に貯留された排水は排水用弁を通って、公共用下水道などへ排出される。そして、第２集水タンク内の排水が排出されると、各弁を上記と反対に開閉する。そして、これを繰り返すことにより、２台の集水タンクを交互に作動させて排水の貯留と下水道などへの排水とを行う。   According to the ninth aspect of the present invention, when one of the two water collection tanks, for example, the vacuum pump switching valve and the tank switching valve is opened with the air release valve and the drainage valve of the first water collection tank closed. The first water collection tank is depressurized to a certain vacuum pressure by a vacuum pump, the suction pipe connected to the first water collection tank is also depressurized to a certain vacuum pressure, and the suction pipe vacuums the drainage in the detection tank. And let it flow into the first water collection tank. In addition, when the other water collection tank, for example, the vacuum pump switching valve and the tank switching valve of the second water collection tank is closed, the air release valve of the second water collection tank is opened, so that Air is sucked into the water collection tank, and the second water collection tank becomes atmospheric pressure. When the drainage valve is opened in this state, the wastewater stored in the second water collection tank passes through the drainage valve and is discharged to the public sewer. And if the waste_water | drain in a 2nd water collection tank is discharged | emitted, each valve will be opened and closed contrary to the above. Then, by repeating this, the two water collecting tanks are alternately operated to store the waste water and drain the water into the sewer.

このような真空排出システムに仮に強制圧送ポンプ用いて集水タンク内の排水を排出すると、小型の集水タンクを使用した場合吸引管内の真空圧が設定値以上に高くなる恐れがあるが、集水タンク内を大気開放して、集水タンク内の排水を自然排水することにより、吸引管内の圧力異常を防ぎ、安定した運転をすることができる。   If drainage in the water collection tank is discharged to such a vacuum discharge system using a forced pressure pump, the vacuum pressure in the suction pipe may become higher than the set value when a small water collection tank is used. By opening the water tank to the atmosphere and allowing the drainage in the water collection tank to drain naturally, abnormal pressure in the suction pipe can be prevented and stable operation can be achieved.

また、２台の集水タンクを交互に作動させることにより、吸引管内の真空度はほぼ一定に保たれ、吸引管などの管路は壊れにくい。   Further, by alternately operating the two water collection tanks, the degree of vacuum in the suction pipe is kept almost constant, and the pipe line such as the suction pipe is not easily broken.

さらに、仮に一方の真空タンクが故障しても、他方の集水タンクは集排水することができるため、集水タンク内の排水の排出時間を除けば、検知枡内の排水を集水タンクに吸引するができる。   Furthermore, even if one vacuum tank breaks down, the other water collection tank can collect and drain the water. Therefore, except for the drainage time of the drainage in the water collection tank, the drainage in the detection tank is sent to the water collection tank. Can suck.

集水タンク２０は２台あり、吸引管１２は第１および第２接続管１２ａ，１２ｂに分かれて、２台の集水タンク２０とそれぞれ接続する。すなわち、第１接続管１２ａはタンク切替用電動弁６０ａを介して第１集水タンク２０ａと接続し、第２接続管１２ｂはタンク切替用電動弁６０ｂを介して第２集水タンク２０ｂと接続する。   There are two water collection tanks 20, and the suction pipe 12 is divided into first and second connection pipes 12a and 12b, which are connected to the two water collection tanks 20, respectively. That is, the first connection pipe 12a is connected to the first water collection tank 20a via the tank switching electric valve 60a, and the second connection pipe 12b is connected to the second water collection tank 20b via the tank switching electric valve 60b.

One end of the first and second drain pipes 70a, 70b is connected to the lower surface of each of the first and second water collection tanks 20a, 20b, and the other end of the first and second drain pipes 70a, 70b is the drainage electric valve 72a. , 72b, respectively, and the drain main 70 is connected to a public sewer.

この各集水タンク２０内にフロートスイッチ７４を設ける。フロートスイッチ７４は複数、この実施例では３個のフロート７４ａ、７４ｂ、７４ｃを有し、集水タンク２０内の排水水位の上昇または下降を検知する。制御線２６で制御盤７６は各フロートスイッチ７４、各タンク切替用電動弁６０ａ、６０ｂ、各真空ポンプ切替用電動弁６４ａ、６４ｂ、各大気開放用電動弁６８ａ、６８ｂおよび各排水用電動弁７２ａ、７２ｂと接続し、フロートスイッチ７４の信号により制御盤７６は作動して各電動弁を制御する。   A float switch 74 is provided in each water collection tank 20. The float switch 74 has a plurality of float switches 74a, 74b, and 74c in this embodiment, and detects the rise or fall of the drainage water level in the water collection tank 20. At the control line 26, the control panel 76 is connected to each float switch 74, each tank switching motor-operated valve 60a, 60b, each vacuum pump switching motor-operated valve 64a, 64b, each atmosphere opening motor-operated valve 68a, 68b, and each drainage motor-operated valve 72a. , 72b, and the control panel 76 is operated by the signal of the float switch 74 to control each motor operated valve.

このような真空排水システム１０において、第１集水タンク２０ａのタンク切替用電動弁６０ａおよび真空ポンプ切替用電動弁６４ａを閉じ、大気開放用電動弁６８ａおよび排水用電動弁７２ａを開いた状態で、第１集水タンク２０ａ内の排水を排出する。そして、フロートスイッチ７４ｃがオフになったら、制御盤７６はすぐに大気開放用電動弁６８ａおよび排水用電動弁７２ａは閉じてから、真空ポンプ切替用電動弁６４ａを開いて、真空ポンプ１８により第１集水タンク２０ａ内の空気を吸引して、第１集水タンク２０ａ内の真空度を、たとえば−４〜−５ＭＡｑまで高めておく。一方、第２集水タンク２０ｂでは、大気開放用電動弁６８ｂおよび排水用電動弁７２ｂを閉じ、タンク切替用電動弁６０ｂおよび真空ポンプ切替用電動弁６４ｂを開いて、検知枡１６から排水を集水する。そして、第２集水タンク２０ｂ内の排水水位が上昇して、この上昇に伴い中位フロート７４ｂも上昇してオンすると、制御盤７６は第２集水タンク２０ｂのタンク切替用電動弁６０ｂおよび真空ポンプ切替用電動弁６４ｂを閉じ、大気開放用電動弁６８ｂを開いて、大気開放用電動弁６８ｂから第２集水タンク２０ｂへ空気を吸引して第２集水タンク２０ｂ内は大気圧にし、排水用電動弁７２ｂを開いて、第２集水タンク２０ｂ内の排水１４を排水用電動弁７２ｂを通して、公共下水道などへ排出する。これと同時に、制御盤７６は真空状態になっている第１集水タンク２０ａのタンク切替用電動弁６０ａを開く。   In such a vacuum drainage system 10, the tank switching electric valve 60 a and the vacuum pump switching electric valve 64 a of the first water collection tank 20 a are closed, and the atmosphere opening electric valve 68 a and the drainage electric valve 72 a are opened. The waste water in the first water collection tank 20a is discharged. When the float switch 74c is turned off, the control panel 76 immediately closes the motor valve 68a for opening the atmosphere and the motor valve 72a for drainage, and then opens the motor valve 64a for switching the vacuum pump, and the vacuum pump 18 performs the first operation. The air in the 1st water collection tank 20a is attracted | sucked, and the vacuum degree in the 1st water collection tank 20a is raised to -4 to -5MAq, for example. On the other hand, in the second water collection tank 20b, the motor valve 68b for opening to the atmosphere and the motor valve 72b for draining are closed, the motor valve 60b for switching tanks and the motor valve 64b for switching vacuum pumps are opened, and drainage is collected from the detection rod 16. Water. Then, when the drainage water level in the second water collection tank 20b rises and the middle float 74b rises and turns on along with this rise, the control panel 76 controls the tank switching electric valve 60b of the second water collection tank 20b and The vacuum pump switching motor-operated valve 64b is closed, the atmosphere-opening motor-operated valve 68b is opened, and air is sucked from the atmosphere-opening motor-operated valve 68b to the second water collecting tank 20b to bring the second water collecting tank 20b to atmospheric pressure. Then, the drainage electric valve 72b is opened, and the drainage 14 in the second water collecting tank 20b is discharged to the public sewer through the drainage electric valve 72b. At the same time, the control panel 76 opens the tank switching electric valve 60a of the first water collection tank 20a in a vacuum state.

このとき、吸引管１２内の真空弁３８を閉じておき、吸引管１２により検知枡１６内の排水１４を吸引せず、水使用設備４２から排出される排水１４を検知枡１６内に流入させて貯留する。そして、検知枡１６内の排水１４の水位が上昇して増水水位センサ２４の高さＭ、たとえば１５ｃｍ以上になると、図３に示すように、ステップＳ１０１で増水水位センサ２４はオンされ、ステップＳ１０３により真空電磁弁２８のタイマ３０は作動するとともに、真空電磁弁２８は真空取出口３６からの真空を利用して真空弁３８を開く。これにより、検知枡１６から集水タンク２０までの間の吸引管１２内は吸引されて、吸引管１２は検知枡１６内の排水１４を吸引する。排水１４は吸引管１２を通り、第１集水タンク２０ａ内に流入する。そして、ステップＳ１０５において真空電磁弁２８のタイマ３０の設定時間、たとえば８秒間吸引して、約２５リットルの排水１４を吸引した後、ステップＳ１０７により真空電磁弁２８は真空弁３８を閉じる。この吸引時間は吸引管１２が検知枡１６内の排水１４のみを吸引するだけの時間であり、検知枡１６内の水位が下がって排水１４とともに空気も吸引するまでに、真空弁３８は閉じられる。このため、図２（Ｂ）に示すように、吸引される排水１４の量の約２５リットルは検知枡１６内に貯留された排水１４の量の約４５リットルの５／９程度であり、吸引後の検知枡１６内には約２０リットルの排水１４が残った状態となる。すなわち、吸引を開始するときの検知枡１６内に貯留された排水１４の水位Ｍは１５ｃｍであり、８秒間吸引した後、排水１４の水位Ｎは約８ｃｍ下がり、検知枡１６内には水位Ｐが約７ｃｍの排水１４が残る。そして、吸引管１２が接続する検知枡１６の接続口の上端は底から高さＴが約５ｃｍの位置に設けられているため、吸引管１２の接続口は残った排水１４内に浸る。   At this time, the vacuum valve 38 in the suction pipe 12 is closed, and the waste water 14 in the detection bottle 16 is not sucked by the suction pipe 12, and the waste water 14 discharged from the water use facility 42 is caused to flow into the detection bowl 16. And store. When the water level of the waste water 14 in the detection rod 16 rises and becomes a height M of the increased water level sensor 24, for example, 15 cm or more, as shown in FIG. 3, the increased water level sensor 24 is turned on in step S101, and step S103. As a result, the timer 30 of the vacuum electromagnetic valve 28 operates and the vacuum electromagnetic valve 28 opens the vacuum valve 38 using the vacuum from the vacuum outlet 36. Thereby, the inside of the suction pipe 12 between the detection rod 16 and the water collection tank 20 is sucked, and the suction tube 12 sucks the waste water 14 in the detection rod 16. The drainage 14 passes through the suction pipe 12 and flows into the first water collection tank 20a. In step S105, the vacuum solenoid valve 28 closes the vacuum valve 38 in step S107 after suctioning about 25 liters of drainage 14 by sucking the set time of the timer 30 of the vacuum solenoid valve 28, for example, 8 seconds. This suction time is a time required for the suction pipe 12 to suck only the waste water 14 in the detection rod 16, and the vacuum valve 38 is closed until the water level in the detection rod 16 falls and air is also sucked together with the drainage 14. . For this reason, as shown in FIG. 2B, about 25 liters of the amount of drained water 14 to be sucked is about 5/9 of about 45 liters of the amount of drained water 14 stored in the detection rod 16, About 20 liters of drainage 14 remains in the later detection rod 16. That is, the water level M of the drainage 14 stored in the detection rod 16 at the start of suction is 15 cm, and after suctioning for 8 seconds, the water level N of the drainage 14 is lowered by about 8 cm. However, about 7 cm of drainage 14 remains. And since the upper end of the connection port of the detection rod 16 to which the suction tube 12 is connected is provided at a height T of about 5 cm from the bottom, the connection port of the suction tube 12 is immersed in the remaining drainage 14.

図１に示すように、吸引管１２に吸引された排水１４は吸引管１２内を移動して、集水タンク２０へ搬送される。なお、真空弁３８を開放している間だけ、検知枡１６内の排水１４は吸引管１２に吸引され、吸引管１２内を移動して、真空弁３８を閉じると、吸引管１２内の排水１４は移動せず、吸引管１２の中は排水１４に満たされる。このため、吸引管１２内は排水１４に満たされているが、吸引管１２内の真空取出口３６を真空弁３８と集水タンク２０との間で最も高い位置に設けることにより、真空取出口３６の上側開口から延びる真空管３２に排水１４が流入せず、真空取出口３６、真空電磁弁２８および真空弁３８を結ぶ真空管３２、３４内は常に真空状態となる。このため、真空電磁弁２８は真空取出口３６から真空管３２を通じて真空を得て、これを利用して真空弁３８を開閉する。   As shown in FIG. 1, the waste water 14 sucked into the suction pipe 12 moves through the suction pipe 12 and is conveyed to the water collection tank 20. Only when the vacuum valve 38 is open, the waste water 14 in the detection rod 16 is sucked into the suction pipe 12, moves in the suction pipe 12, and closes the vacuum valve 38, so that the waste water in the suction pipe 12 is drained. 14 does not move, and the suction pipe 12 is filled with drainage 14. For this reason, the inside of the suction pipe 12 is filled with the drainage 14, but the vacuum outlet is provided by providing the vacuum outlet 36 in the suction pipe 12 at the highest position between the vacuum valve 38 and the water collection tank 20. The drainage 14 does not flow into the vacuum tube 32 extending from the upper opening of 36, and the vacuum tubes 32 and 34 connecting the vacuum outlet 36, the vacuum electromagnetic valve 28, and the vacuum valve 38 are always in a vacuum state. Therefore, the vacuum electromagnetic valve 28 obtains a vacuum from the vacuum outlet 36 through the vacuum tube 32, and uses this to open and close the vacuum valve 38.

また、建物の梁７８などにより吸引管１２が上下して配置されても、吸引管１２内は真空状態となっているので、排水１４は重力に抗して鉛直上方へ搬送され、集水タンク２０に流入する。   Further, even if the suction pipe 12 is arranged up and down by the beam 78 of the building or the like, since the inside of the suction pipe 12 is in a vacuum state, the drainage 14 is conveyed vertically upward against gravity, and the water collecting tank 20 flows in.

そして、再び検知枡１６内の排水１４が増水水位センサ２４の位置Ｍ以上になると、真空電磁弁２８は真空弁３８を開放して、吸引管１２は排水１４を吸引し、吸引管１２内の排水１４は集水タンク２０の方へ移動し始めて、集水タンク２０へ搬送される。これを複数回繰り返すと、第１集水タンク２０ａ内の排水１４の水位は上昇する。この上昇に伴い、フロートスイッチ７４のフロートも上昇してオンする。集水タンク２０の集水時間に比べて排水時間は短いため、第１集水タンク２０ａ内のフロートスイッチ７４のフロートがオンするときには、第２集水タンク２０ｂ内の排水が排出されており、排出が終了するとすぐに第２集水タンク２０ｂの大気開放用電動弁６８ｂおよび排水用電動弁７２ｂを閉じ、真空ポンプ切替用電動弁６４ｂを開いて、第２集水タンク２０ｂ内の真空度は高められている。   When the drainage 14 in the detection rod 16 reaches the position M of the increased water level sensor 24 again, the vacuum electromagnetic valve 28 opens the vacuum valve 38, the suction pipe 12 sucks the drainage 14, and the suction pipe 12 The drainage 14 starts to move toward the water collection tank 20 and is conveyed to the water collection tank 20. If this is repeated a plurality of times, the water level of the waste water 14 in the first water collection tank 20a rises. With this rise, the float of the float switch 74 is also raised and turned on. Since the drainage time is shorter than the water collection time of the water collection tank 20, when the float of the float switch 74 in the first water collection tank 20a is turned on, the wastewater in the second water collection tank 20b is discharged, As soon as the discharge is completed, the motor valve 68b for opening the atmosphere and the motor valve 72b for drainage of the second water collecting tank 20b are closed, the motor valve 64b for switching the vacuum pump is opened, and the degree of vacuum in the second water collecting tank 20b is Has been enhanced.

第１集水タンク２０ａ内のフロートスイッチ７４がオンすると、第１および第２集水タンク２０ａ、２０ｂの集排水を交代する。すなわち、制御盤７６は第１集水タンク２０ａのタンク切替用電動弁６０ａおよび真空ポンプ切替用電動弁６４ａを閉じてから、第１集水タンク２０ａの大気開放用電動弁６８ａおよび排水用電動弁７２ａを開く。これにより、大気開放用電動弁６８ａから第１集水タンク２０ａへ空気は流入し、第１集水タンク２０ａ内は大気圧となり、排水用電動弁７２ａから第１集水タンク２０ａ内の排水１４は公共下水道などへ排出される。これと同時に、制御盤７６は、真空状態の第２集水タンク２０ｂのタンク切替用電動弁６０ｂを開き、第２集水タンク２０ｂを真空状態の吸引管１２および真空管３２、３４と連結する。こうして第２集水タンク２０ｂが真空状態になってから吸引管１２などと接続すれば、吸引管１２および真空管３２、３４の真空状態を維持することができる。   When the float switch 74 in the first water collection tank 20a is turned on, the collection and drainage of the first and second water collection tanks 20a and 20b are changed. That is, after the control panel 76 closes the tank switching motor-operated valve 60a and the vacuum pump switching motor-operated valve 64a of the first water collection tank 20a, the motor-release valve 68a and the drainage motor-operated valve of the first water collection tank 20a are opened. Open 72a. As a result, air flows into the first water collection tank 20a from the motor valve 68a for opening to the atmosphere, the inside of the first water collection tank 20a becomes atmospheric pressure, and the drainage 14 in the first water collection tank 20a from the electric valve for drainage 72a. Is discharged into public sewers. At the same time, the control panel 76 opens the tank switching motor-operated valve 60b of the second water collection tank 20b in the vacuum state, and connects the second water collection tank 20b to the suction pipe 12 and the vacuum pipes 32 and 34 in the vacuum state. If the second water collection tank 20b is connected to the suction pipe 12 after the second water collection tank 20b is in a vacuum state, the vacuum state of the suction pipe 12 and the vacuum pipes 32 and 34 can be maintained.

このように、タイマ３０により検出枡内の排水１４を吸引し始めてから一定時間が経過した後に真空弁３８を閉じるようにすれば、常に一定量の排水１４が吸引される。そして、このタイマ３０の時間を、排水１４を吸引し始めてから空気が吸い込まれるまでの時間に設定すると、吸引管１２は排水１４だけを吸引するため、吸引管１２が排水１４とともに空気を吸い込む際に生じる音を抑制することができる。また、このタイマ３０の設定時間を調整することにより、排水１４の吸引量を変更することができるため、このシステムはどのような大きさの検知枡１６に対しても採用することができる。   As described above, if the vacuum valve 38 is closed after a predetermined time has elapsed after the timer 30 starts to suck the waste water 14 in the detection tank, a constant amount of the waste water 14 is always sucked. When the time of the timer 30 is set to the time from when the drainage 14 starts to be sucked until the air is sucked, the suction pipe 12 sucks only the drainage 14, and therefore when the suction pipe 12 sucks the air together with the drainage 14. It is possible to suppress sound generated in Further, since the suction amount of the drainage 14 can be changed by adjusting the set time of the timer 30, the system can be adopted for any size detection rod 16.

また、真空取出口３６を真空弁３８と集水タンク２０との間で最も高い位置に設ければ、吸引管１２内に排水１４が満たされていても、最も高い位置の真空状態は保たれており、排水１４は真空取出口３６の上側開口から延びる真空管３２内に進入せず、真空管３２内を真空に維持することができるため、真空電磁弁２８はこの真空を利用して、真空弁３８を安定して作動させることができる。   Further, if the vacuum outlet 36 is provided at the highest position between the vacuum valve 38 and the water collection tank 20, the vacuum state at the highest position is maintained even if the drainage 14 is filled in the suction pipe 12. Since the drainage 14 does not enter the vacuum tube 32 extending from the upper opening of the vacuum outlet 36 and the vacuum tube 32 can be maintained in a vacuum, the vacuum electromagnetic valve 28 uses this vacuum to 38 can be stably operated.

排水１４を吸引して集水タンク２０へ搬送するため、吸引管１２に下り勾配をつける必要がなく、吸引管１２が水平または上方へ傾いていても、吸引管１２内の真空圧と大気圧との圧力差に相当する距離だけ、排水１４を上方へ吸い上げることができる。このため、建物の梁７８などがあり吸引管１２の配管面が凸凹していても、吸引管１２を曲げたり迂回させたりして、吸引管１２などの配管を自由に設置することができる。   Since the drainage 14 is sucked and conveyed to the water collection tank 20, it is not necessary to make the suction pipe 12 downwardly inclined, and the vacuum pressure and the atmospheric pressure in the suction pipe 12 can be obtained even if the suction pipe 12 is inclined horizontally or upward. The drainage 14 can be sucked upward by a distance corresponding to the pressure difference between For this reason, even if there is a building beam 78 or the like and the pipe surface of the suction pipe 12 is uneven, the pipe such as the suction pipe 12 can be freely installed by bending or bypassing the suction pipe 12.

２台の集水タンク２０ａ、２０ｂを利用して、一方の集水タンク２０を大気開放して大気圧にした状態で、集水タンク２０内に貯留された排水１４を公共下水道などへ排出し、他方の集水タンク２０内を真空にして、吸引管１２などと連結して検知枡１６内の排水１４を吸引する。そして、この集排水を交互にすることにより、常に一方の集水タンク２０は真空状態にあるため、吸引管１２などの真空度をほぼ一定に維持することができ、安定して排水１４を集水することができる。このため、仮に一方の集水タンク２０が故障しても、他方の集水タンク２０内は集排水を行うことができ、この排水時間を待てば、水使用設備４２を使用することができる。   Using two water collection tanks 20a and 20b, with one of the water collection tanks 20 open to the atmosphere and at atmospheric pressure, the waste water 14 stored in the water collection tank 20 is discharged to a public sewer. Then, the other water collection tank 20 is evacuated and connected to the suction pipe 12 or the like to suck the waste water 14 in the detection tank 16. By alternating the collection and drainage, since one of the collection tanks 20 is always in a vacuum state, the degree of vacuum of the suction pipe 12 and the like can be maintained almost constant, and the drainage 14 can be collected stably. Can be water. For this reason, even if one of the water collection tanks 20 breaks down, the other water collection tank 20 can collect and drain water. If this drainage time is waited, the water use facility 42 can be used.

なお、真空排水システム１０を２階以上の建物に採用する場合、真空取出口３６は各階の最高位置に設ける。   In addition, when employ | adopting the vacuum drainage system 10 in the 2nd floor or more building, the vacuum outlet 36 is provided in the highest position of each floor.

また、真空取出口３６の吸引管１２からの分岐点を真空弁３８と集水タンク２０との間の最も高い位置に設けたが、図４に示すように、真空弁３８と集水タンク２０との間の最も高い位置でない位置から分岐させて、真空取出口３６を真空弁３８と集水タンク２０との間における吸引管１２に比べて高い位置に設けてもよい。   Further, the branch point from the suction pipe 12 of the vacuum outlet 36 is provided at the highest position between the vacuum valve 38 and the water collection tank 20, but the vacuum valve 38 and the water collection tank 20 are provided as shown in FIG. The vacuum outlet 36 may be provided at a higher position than the suction pipe 12 between the vacuum valve 38 and the water collection tank 20.

図５に示すこの発明の他の実施例である真空排水システム１０は図１に示す真空排水システム１０とほぼ同じであるが、吸引の停止方法が異なる。図１に示す真空排水システム１０では検知枡１６内の排水１４を吸引した際、タイマ３０により吸引を停止したが、図５に示す真空排水システム１０では検知枡１６内に配置した水位センサにより検知枡１６内の排水１４の吸引を停止する。これ以外の部分に関しては図１実施例の示す真空排水システム１０と同様であるため、説明は省略する。   A vacuum drainage system 10 according to another embodiment of the present invention shown in FIG. 5 is substantially the same as the vacuum drainage system 10 shown in FIG. 1, but the suction stop method is different. In the vacuum drainage system 10 shown in FIG. 1, when the drainage 14 in the detection rod 16 is sucked, the suction is stopped by the timer 30, but in the vacuum drainage system 10 shown in FIG. 5, the detection is performed by the water level sensor arranged in the detection rod 16. The suction of the drainage 14 in the gutter 16 is stopped. Since other parts are the same as the vacuum drainage system 10 shown in FIG.

図６に示すように、検知枡１６内に増水水位センサ２４および減水水位センサ８０を据え、一方の増水水位センサ２４は上記の増水水位センサ２４と同様に、排水管４０の接続口より下方であり、検知枡１６の底からの高さＭたとえば、約１５ｃｍの位置を測定するように設置する。他方の減水水位センサ８０はタイマ３０に代わるものとして、吸引管１２の接続口の高さＴ：５ｃｍより上の位置、たとえば検知枡１６の底から高さＳ：約７ｃｍの位置に設ける。この場合、検知枡１６内に排水１４が溜まり、排水１４の水位が高さＭ：約１５ｃｍになると、図７に示すように、ステップＳ１１１で増水水位センサ２４がオンし、ステップＳ１１３により真空電磁弁２８を作動して、真空電磁弁２８は真空弁３８を開き、吸引管１２は検知枡１６内の排水１４のみを吸引する。排水１４が吸引されて水位が高さＳ：約７ｃｍの位置になると、ステップＳ１１５で減水水位センサ８０がオフし、ステップＳ１１７により真空電磁弁２８は真空弁３８を閉じて、吸引管１２は空気を吸い込む前に吸引を止める。   As shown in FIG. 6, the increased water level sensor 24 and the decreased water level sensor 80 are installed in the detection tank 16, and one of the increased water level sensors 24 is located below the connection port of the drain pipe 40, similar to the increased water level sensor 24 described above. Yes, the height M from the bottom of the detection rod 16, for example, is set to measure a position of about 15 cm. The other water-reduced water level sensor 80 replaces the timer 30 and is provided at a position above the connection port height T: 5 cm, for example, at a height S: about 7 cm from the bottom of the detection rod 16. In this case, when the drainage 14 accumulates in the detection rod 16 and the water level of the drainage 14 reaches a height M: about 15 cm, the increased water level sensor 24 is turned on in step S111 as shown in FIG. By operating the valve 28, the vacuum electromagnetic valve 28 opens the vacuum valve 38, and the suction pipe 12 sucks only the drainage 14 in the detection rod 16. When the drainage 14 is sucked and the water level is at the height S: about 7 cm, the reduced water level sensor 80 is turned off in step S115, the vacuum electromagnetic valve 28 closes the vacuum valve 38 in step S117, and the suction pipe 12 is air. Stop inhalation before inhaling.

図８に示すこの発明の他の実施例である真空排水システム８２は図１に示す真空排水システム１０とほぼ同じであるが、排水１４の貯留方法が異なる。図１に示す真空排水システム１０では便器４２などから排出される排水１４を一度検知枡１６に貯留して、そこから排水１４を吸引して集水タンク２０へ移したが、図８に示す真空排水システム８２は便器８４内の排水１４を直接吸引して集水タンク２０へ搬送する。これ以外の部分に関しては図１実施例の示す真空排水システム１０と同様であるため、説明は省略する。   A vacuum drainage system 82, which is another embodiment of the present invention shown in FIG. 8, is substantially the same as the vacuum drainage system 10 shown in FIG. In the vacuum drainage system 10 shown in FIG. 1, the drainage 14 discharged from the toilet 42 and the like is once stored in the detection basket 16, and the drainage 14 is sucked from there and transferred to the water collecting tank 20. The drainage system 82 directly sucks the drainage 14 in the toilet bowl 84 and transports it to the water collection tank 20. Since other parts are the same as the vacuum drainage system 10 shown in FIG.

便器８４は便器８４内の排水を排出するための排出スイッチ８６を備え、この排出スイッチ８６は制御線２６により真空電磁弁２８と接続する。真空電磁弁２８はタイマ３０を内蔵し、２つの真空管３２、３４と接続する。２つの真空管３２、３４の内の一方の真空管３２は真空取出口３６と連結し、他方の真空管３４は真空弁３８と連結する。   The toilet 84 includes a discharge switch 86 for discharging the waste water in the toilet 84, and the discharge switch 86 is connected to the vacuum electromagnetic valve 28 through the control line 26. The vacuum electromagnetic valve 28 includes a timer 30 and is connected to the two vacuum tubes 32 and 34. One of the two vacuum tubes 32, 34 is connected to a vacuum outlet 36, and the other vacuum tube 34 is connected to a vacuum valve 38.

図９に示すように、ステップＳ１３１でこのような便器８４の排出スイッチ８６をオンすると、ステップＳ１３３においてタイマ３０は作動し始めるとともに、真空電磁弁２８は真空弁３８を開く。真空弁３８が開くと、吸引管１２は便器８４から集水タンク２０まで繋がり、便器８４内の排水１４は吸引管１２により吸引され、集水タンク２０へ搬送される。そして、ステップＳ１３５で排水１４を吸引し始めてから一定時間、たとえば３秒間が経過すると、タイマ３０がタイムアップしてステップＳ１３７において真空電磁弁２８は真空弁３８を閉じる。このタイマ３０の設定時間は吸引管１２が排水１４を吸引し始めてから空気を吸い込むまでの時間である。そして、便器８４内の排水１４を排出してから、便器８４内に給水する。   As shown in FIG. 9, when the discharge switch 86 of the toilet 84 is turned on in step S131, the timer 30 starts operating in step S133, and the vacuum electromagnetic valve 28 opens the vacuum valve 38. When the vacuum valve 38 is opened, the suction pipe 12 is connected from the toilet bowl 84 to the water collection tank 20, and the waste water 14 in the toilet bowl 84 is sucked by the suction pipe 12 and conveyed to the water collection tank 20. Then, when a predetermined time, for example, 3 seconds elapses after the suction of the waste water 14 is started in step S135, the timer 30 expires and the vacuum electromagnetic valve 28 closes the vacuum valve 38 in step S137. The set time of the timer 30 is the time from when the suction pipe 12 starts sucking the drainage 14 until the air is sucked. Then, after draining the waste water 14 in the toilet bowl 84, water is supplied into the toilet bowl 84.

この場合、吸引管１２は３秒間の間に約１１リットルの排水１４を吸引し、吸引後の便器８４内には、吸引管１２の開口を浸すだけの排水１４が残る。このため、吸引管１２は便器８４内の排水１４のみを吸引し、排水１４とともに空気を吸い込んだ際に生じる吸引音を抑制する。   In this case, the suction pipe 12 sucks about 11 liters of the waste water 14 for 3 seconds, and the waste water 14 just soaking the opening of the suction pipe 12 remains in the toilet 84 after the suction. For this reason, the suction pipe 12 sucks only the waste water 14 in the toilet 84 and suppresses suction sound generated when air is sucked together with the waste water 14.

このように、吸引管１２は便器８４内の排水１４のみを吸引することにより、空気を吸い込んだ際の排水音を抑制し、静かな排水１４を実現することができる。   As described above, the suction pipe 12 sucks only the drainage 14 in the toilet bowl 84, thereby suppressing the drainage sound when air is sucked in and realizing the quiet drainage 14.

また、便器８４内の排水１４の量や吸引管１２の接続口などに応じて、吸引管１２が排水１４のみを吸引するように、タイマ３０の時間を設定することができる。このため、便器８４内の排水１４の吸引量を簡単に設定できるため、この真空排水システム８２はどのようなタイプの便器にも適用することができる。   Further, the time of the timer 30 can be set so that the suction pipe 12 sucks only the drainage 14 according to the amount of the drainage 14 in the toilet bowl 84, the connection port of the suction pipe 12, and the like. For this reason, since the suction | attraction amount of the waste_water | drain 14 in the toilet bowl 84 can be set easily, this vacuum drainage system 82 is applicable to any type of toilet bowl.

さらに、便器８４内の排水１４を吸引することにより、サイフォン式便器のようなサイフォン作用を起こさせるための洗浄水が不要であり、水の使用量が少なく、節水を図ることができる。   Furthermore, by sucking the waste water 14 in the toilet bowl 84, no washing water for causing siphon action like a siphon type toilet bowl is required, the amount of water used is small, and water can be saved.

さらに、この真空排水システム８２を用いることにより、完全クローズ配管が可能になる。   Furthermore, by using this vacuum drainage system 82, completely closed piping is possible.

なお、図１、図５および図８実施例では、集水タンク２０ａ、２０ｂに別々の電動弁を接続し、制御盤７６により各電動弁を制御したが、図１０に示すように、電動三方弁により２台のタンク２０ａ、２０ｂを接続し、１つの制御盤７６により各電動三方弁を制御してもよい。この場合、吸引管１２は第１および第２接続管１２ａ，１２ｂに分岐し、第１および第２接続管１２ａ，１２ｂはタンク切替用電動三方弁８８を介して第１および第２集水タンク２０ａ、２０ｂとそれぞれ接続する。また、第１および第２集水タンク２０ａ、２０ｂには真空管６２ａ、６２ｂの一端がそれぞれ接続し、真空管６２ａ、６２ｂの他端は真空ポンプ１８が連結する真空ポンプ切替用電動三方弁９０にそれぞれ接続する。さらに、第１および第２集水タンク２０ａ、２０ｂの上面に大気開放管６６ａ、６６ｂの一端が接続し、大気開放管６６ａ、６６ｂの他端に一端が大気開放された大気開放用電動三方弁９２が接続する。そして、第１および第２集水タンク２０ａ、２０ｂの下面に排水管７０ａ、７０ｂが接続し、排水管７０ａ、７０ｂは排水用電動三方弁９４を介して公共下水道などに連結する排水本管７０と接続する。   1, FIG. 5 and FIG. 8 embodiment, separate electric valves are connected to the water collecting tanks 20a and 20b, and each electric valve is controlled by the control panel 76. However, as shown in FIG. The two tanks 20 a and 20 b may be connected by a valve, and each electric three-way valve may be controlled by one control panel 76. In this case, the suction pipe 12 is branched into first and second connection pipes 12a and 12b, and the first and second connection pipes 12a and 12b are connected to the first and second water collection tanks via the tank switching electric three-way valve 88. Connected to 20a and 20b, respectively. One end of vacuum tubes 62a and 62b is connected to the first and second water collection tanks 20a and 20b, respectively, and the other end of the vacuum tubes 62a and 62b is connected to a vacuum pump switching electric three-way valve 90 connected to the vacuum pump 18, respectively. Connecting. In addition, an atmospheric open electric three-way valve in which one end of the atmospheric release pipes 66a and 66b is connected to the upper surfaces of the first and second water collection tanks 20a and 20b, and one end of the atmospheric release pipes 66a and 66b is open to the atmosphere. 92 connects. Then, drain pipes 70a and 70b are connected to the lower surfaces of the first and second water collection tanks 20a and 20b, and the drain pipes 70a and 70b are connected to a public sewer or the like via a drainage electric three-way valve 94. Connect with.

そして、制御線２６により各集水タンク２０内に設けられたフロートスイッチ７４および各電動三方弁は制御盤７６と接続する。フロートスイッチ７４がオンすると、それに応じて制御盤７６は各電動三方弁８８、９０、９２、９４を制御する。たとえば、第１集水タンク２０ａに集水され、排水水位が上昇して、フロートスイッチ７４の中位フロート７４ｂがオンし、第２集水タンク２０ｂに設けたフロートスイッチ７４の下位フロート７４ｃがオフされていれば、制御盤７６はタンク切替用電動三方弁８８および真空ポンプ切替用電動三方弁９０を第１集水タンク２０ａ側から第２集水タンク２０ｂ側に切り替え、大気開放用電動三方弁９２および排水用電動三方弁９４を第２集水タンク２０ｂ側から第１集水タンク２０ａ側に切り替える。これにより、第１集水タンク２０ａのタンク切替用電動三方弁８８および真空ポンプ切替用電動三方弁９０を閉じ、第１集水タンク２０ａの大気開放用電動三方弁９２および排水用電動三方弁９４を開く。そして、第１集水タンク２０ａは大気開放用電動三方弁９２から空気を吸い込み大気圧となって、第１集水タンク２０ａ内の排水１４は排水用電動三方弁９４から公共下水道などへ排出される。一方、第２集水タンク２０ｂの大気開放用電動三方弁９２および排水用電動三方弁９４を閉じて、第２集水タンク２０ｂの真空ポンプ切替用電動三方弁９０を開く。すると、真空ポンプ１８は第２集水タンク２０ｂ内の空気を吸引して、第２集水タンク２０ｂは真空状態となり、吸引管１２および真空管３２、３４と連結して、検知枡１６内の排水１４を吸引する。   The float switch 74 and each electric three-way valve provided in each water collection tank 20 are connected to the control panel 76 by the control line 26. When the float switch 74 is turned on, the control panel 76 controls the electric three-way valves 88, 90, 92, 94 accordingly. For example, water is collected in the first water collection tank 20a, the drainage water level rises, the middle float 74b of the float switch 74 is turned on, and the lower float 74c of the float switch 74 provided in the second water collection tank 20b is turned off. If so, the control panel 76 switches the tank switching electric three-way valve 88 and the vacuum pump switching electric three-way valve 90 from the first water collection tank 20a side to the second water collection tank 20b side, thereby opening the electric three-way valve for opening to the atmosphere. 92 and the drainage electric three-way valve 94 are switched from the second water collection tank 20b side to the first water collection tank 20a side. As a result, the tank-switching electric three-way valve 88 and the vacuum pump switching electric three-way valve 90 of the first water collection tank 20a are closed, and the atmosphere-opening electric three-way valve 92 and the drainage electric three-way valve 94 of the first water collection tank 20a. open. The first water collection tank 20a sucks air from the open electric three-way valve 92 to atmospheric pressure, and the waste water 14 in the first water collection tank 20a is discharged from the drainage electric three-way valve 94 to the public sewer. The On the other hand, the open electric three-way valve 92 and the drainage electric three-way valve 94 of the second water collection tank 20b are closed, and the vacuum pump switching electric three-way valve 90 of the second water collection tank 20b is opened. Then, the vacuum pump 18 sucks the air in the second water collection tank 20b, the second water collection tank 20b is in a vacuum state, and is connected to the suction pipe 12 and the vacuum pipes 32 and 34, so that the waste water in the detection tank 16 is discharged. 14 is aspirated.
