強制排水装置 発明の属する技術分野  Technical field to which the invention belongs
本発明は、 建造物における便所、 浴室、 洗面所、 台所等の排水源からの汚水や 雑排水を、 建造物外の下水管等へ排出するための排水装置に関し、 特にこれらの 汚水や雑排水を強制的に排出するための強制排水装置に関する。 背景技術  The present invention relates to a drainage device for discharging sewage and gray water from a drainage source such as a toilet, a bathroom, a washroom, and a kitchen to a sewer pipe or the like outside a building. The present invention relates to a forced drainage device for forcibly discharging water. Background art
マンション等の共同住宅や、 戸建て住宅における排水としては、 主として、 台 所、 浴室、 洗面所等から排出される雑排水と、 大小便器等から排出される汚水に 分けられる。 従来、 このような排水を排出するためのシステムとしては、 排水管 の勾配を利用して排出する重力式抹水が一般に採用されている。  Wastewater from apartments and condominiums and detached houses is mainly divided into gray water discharged from pedestals, bathrooms, washrooms, etc., and sewage discharged from large and small urinals. Conventionally, as a system for discharging such wastewater, gravity-type tap water that discharges using the slope of a drainage pipe is generally adopted.
しかし、 重力式排水においては、 排水のために充分な勾配をとつて排水管を設 置する必要があり、 床上や床下に排水管の設置のための多くのスペースが必要と されるため、 排水源である台所、 浴室、 洗面所、 便器等の水回り設備の設置場所 が非常に制約を受けるといった問題があった。  However, gravity drainage requires drainage pipes to be installed at a sufficient gradient for drainage, and a lot of space is required above and below the floor for drainage pipe installation. There was a problem that the location of water supply facilities such as kitchens, bathrooms, washrooms, and toilets, which are the source, was very limited.
ところで、 近年、 共同住宅として水回り設備の間取りに自由度を持たせた設計 に対する需要の高まりや、 オフィスビルから共同住宅へのリフォームに際して、 水回り設備の配置の自由度の高さが要求されている。 しかし、 上述したように、 従来の重力式排水では、 排水管の設置に際して所定の勾配を必要とするため、 こ のような自由度を持たせた設計に対して充分に対応することができず、 自由度の 低い設計を強いられ、 中には困難により計画を中止せざるを得ない場合が生じて いる。  By the way, in recent years, there has been a growing demand for designs that allow flexibility in the layout of plumbing facilities as apartments, and when renovating office buildings into apartments, a high degree of freedom in the placement of plumbing facilities is required. ing. However, as described above, conventional gravity drainage requires a predetermined gradient when installing drainage pipes, and thus cannot sufficiently cope with a design having such a degree of freedom. However, there were cases where the design had to be made with a low degree of freedom, and in some cases the plan had to be canceled due to difficulties.
このような課題を解決するため、 従来、 排水管の設置勾配がない場合や、 逆勾 配の場合でも排水可能なように、 ポンプを利用して圧送する強制排水システム等 が開発されている。 従来の強制排水システムとしては、 下記特許文献 1及び特許 文献 2に開示されたシステムが知られている。 [特許文献 1 ] In order to solve such problems, a forced drainage system that uses a pump to pump water has been developed so that drainage can be performed even when the drainage pipe is not installed or when it is installed in a reverse slope. As conventional forced drainage systems, systems disclosed in Patent Literature 1 and Patent Literature 2 below are known. [Patent Document 1]

上記特許文献 1には、 水道水や空気等の駆動用流体の圧力により排水用羽根車 を回転駆動することで、 固形物を含んだ汚水，雑排水を粉砕し、 強制的に縦管ま で圧送する強制排水システムが開示されている。 また、 上記特許文献 2には、 バ キュームュニッ トによりフィル夕一ュニヅ ト ー封水部間に負圧を発生させて、 排 水を強制的に吸引し排出する排水装置が開示されている。 発明の開示  In Patent Document 1 described above, by rotating a drain impeller by the pressure of a driving fluid such as tap water or air, sewage and miscellaneous wastewater containing solid matter are pulverized and forced to reach a vertical pipe. A forced drainage system for pumping is disclosed. Further, Patent Document 2 discloses a drainage device that generates a negative pressure between a fill unit and a sealed portion by a vacuum unit to forcibly suck and discharge wastewater. Disclosure of the invention
しかし、 上記特許文献 1記載の強制排水システムにおいては、 排水用羽根車、 タービン用羽根車及びこれら羽根車を駆動するための駆動用流体を供給する装置 が必要であり、 構成が複雑となり、 コストも高く、 メンテナンスにも手間がかか つてしまう。 また、 駆動用流体を供給する装置が故障した場合には、 羽根車の回 転が止まってしまうので、 排水管の中に回転しない排水用羽根車が位置し、 却つ て排水を阻害する要因となってしまう。 特に、 汚水管の中の固形物が羽根車に詰 まる可能性が高く、 排水の詰まりの原因になってしまう。 また、 羽根車のメンテ ナンスが必要になった場合には、 排水管の中の作業を行う必要があり、 非常に手 間の係る作業となってしまう。  However, the forced drainage system described in Patent Document 1 requires a drainage impeller, a turbine impeller, and a device for supplying a driving fluid for driving these impellers. The cost is high, and maintenance is troublesome. In addition, if the device that supplies the driving fluid fails, the impeller stops rotating, and a non-rotating drain impeller is located in the drain pipe, which is a factor that hinders drainage. Will be. In particular, the solids in the sewage pipe are likely to clog the impeller, causing clogging of drainage. In addition, when maintenance of the impeller becomes necessary, it is necessary to work inside the drain pipe, which is extremely labor-intensive.
また、 上記特許文献 2記載の強制排水システムにおいても、 バキュームュニヅ トが故障してしまった場合には、 検知装置が排水や目詰まりを検知しても、 空気 吸引による負圧を発生させることができないため、 濾過フィルターでの目詰まり により、 排水詰まりが生じてしまう。  Also, in the forced drainage system described in Patent Document 2 described above, if the vacuum unit has failed, even if the detection device detects drainage or clogging, a negative pressure due to air suction cannot be generated. Therefore, clogging in the filtration filter causes clogging of drainage.
本発明は、 このような課題に鑑みてなされたものであり、 単純な構造且つ駆動 系装置が故障したとしても排水詰まりを生じることのない強制排水装置を提供す ることを目的とする。  The present invention has been made in view of such a problem, and an object of the present invention is to provide a forced drainage device that has a simple structure and does not cause drainage clogging even when a drive system device fails.

Of course, the pipe diameter is not limited to this, and it is possible to appropriately select a pipe diameter of 65 mm, 40 gangs, 32 gangs, etc. according to the building structure and design. However, the initial pressure at the time of jet water jet injection is higher than the water supply pressure due to the compression of the air layer in the indirect pressure water supply tank. The air pressure in the compressed air supply pipe 43 is 0.3 to 0.5 MPa, and the pressure of the air sent from the compressor via the compressed air main pipe 41 is reduced by the air pressure reducing valve 42. As described above, when the air pressure of the jet airflow generating device 40 is 0.3 to 5 MPa, the diameter of the horizontal pipe in which the relay jet airflow nozzle member 45 is installed is to ensure the induction drainage, It is desirable to be 50mni or less.

Fig. 5 (a) is a schematic diagram showing the installation state of the vibration-proof and sound-proof cover, and Fig. 5 (b) is a cutaway view thereof. As shown in FIG. 5, the vibration-proof and sound-proof protective cover 70 is installed so as to cover the main body of a drain pipe such as a connection pipe or a horizontal pipe. The shape of the vibration-proof and sound-proof protective cover 70 is a tubular member having a rectangular cross section. The lower part of the gap between the vibration-proof and sound-proof protective cover and the drain pipe having a circular cross section is filled with dry sand 71.

Further, by filling the sand 71, it is possible to stably prevent the generation of noise and vibration. In addition, a water leak sensor may be installed at the bottom of the vibration and soundproofing protection cover 70. If the water leak sensor is installed, it is possible to reliably detect water leak from the drain pipe.
なお、 防振防音保護カバーを設置せず、 排水管として既存の二重管を用いるこ とでも、 ある程度防振防音の効果が得られるが、 本実施の形態のように防振防音 保護カバ一を設置すれば、 充分な防振防音効果を得ることができる。 また、 リサ イクル品である廃棄タイヤを防振防音保護カバーとして用いているので、 環境保 護にも貢献することができる。  It should be noted that even if the existing double pipe is used as the drainage pipe without installing the vibration and soundproofing protective cover, the effect of vibration and soundproofing and soundproofing can be obtained to some extent. If it is installed, sufficient vibration and soundproofing effects can be obtained. In addition, since recycled tires are used as vibration-proof and sound-proof protective covers, they can also contribute to environmental protection.

まず、 ステップ 1 (以下、 「ステヅプ」 を 「S」 とする） において、 便器 1 6 の排水が行われる。 この排水は、 まず接続管 2 5— 6を通過するので、 S 1 1に おいて、 接続管 2 5— 6に設置された流水検知器 3 7— 6により検知される。 こ の検知により、 流水検知器 3 7 - 6において検知信号が生成され、 制御盤 5 0へ と送信される （S 1 2 ) 。 制御盤 5 0は、 この検知信号に基づいて、 便器 1 6か らの排水が通過するジヱット水流ノズル部材 3 5、 中継ジヱット水流ノズル部材 3 6からジヱット水流を噴射させるための制御信号を生成し （S 1 3 ) 、 ジエツ ト水流発生装置 3 0へ送信する。 具体的には、 ジエツト水流ノズル部材 3 5及び 中継ジェット水流ノズル部材 3 6の各水制御弁 3 2— 6 , 3 2一 5の開閉を制御 する制御信号が生成 ·送信される。  First, in Step 1 (hereinafter, “Step” is referred to as “S”), the toilet bowl 16 is drained. Since this drainage first passes through the connecting pipe 25-6, it is detected in S11 by the flowing water detector 37-6 installed in the connecting pipe 25-6. As a result of this detection, a detection signal is generated in the flowing water detector 37-6, and transmitted to the control panel 50 (S12). The control panel 50 generates a control signal for injecting jet water from the jet water nozzle member 35 through which the drainage from the toilet bowl 16 passes and the relay jet water nozzle member 36 based on the detection signal. (S 13), and sends it to the jet water flow generator 30. Specifically, a control signal for controlling the opening and closing of each water control valve 32-6, 32-15 of the jet water flow nozzle member 35 and the relay jet water flow nozzle member 36 is generated and transmitted.
ジエツト水流ノズル部材 3 5から噴射させるための制御信号としては、 例えば 、 便器 1 6からの排水が流水検知器 3 7— 6を通過し終わり、 制御盤 5 0での検 知信号の受信が停止してから 2〜4秒の間、 水制御弁 3 7— 6を開いてジエツト 水流を噴射させるような制御信号とすれば良い。 また、 中継ジェット水流ノズル 部材 3 6から噴射させるための制御信号としては、 ジエツト水流ノズル部材 3 5 と中継ジエツト水流ノズル部材 3 6との間隔に応じた時間だけ遅延して、 水制御 弁 3 7— 5を 2〜 4秒開いて中継ジェット水流を噴射させるような制御信号とす れば良い。  As a control signal for jetting from the jet water flow nozzle member 35, for example, the drainage from the toilet 16 ends passing through the flow water detector 37-6, and the control panel 50 stops receiving the detection signal. After 2 to 4 seconds, the control signal should be such that the water control valve 37-6 is opened to jet the jet water flow. The control signal for jetting from the relay jet water flow nozzle member 36 includes a water control valve 37 which is delayed by a time corresponding to the interval between the jet water flow nozzle member 35 and the relay jet water nozzle member 36. — Set a control signal that opens 5 to 2 to 4 seconds and injects a relay jet stream.
S 1 5においては、 ジヱット水流ノズル部材 3 5は、 上記制御信号に基づいた 水制御弁 3 7 _ 6の開動作により、 ジェット水流を排水管内に噴射し、 汚水用水 平管 2 3内の排水を強制的に汚水用竪管 2 4に向けて誘導排水する。 この時、 水 供給管 3 4内の圧力 O. lMPaでジエツト水流が噴射されるが、 水制御弁 3 7— 6を 開いた直後の初期圧力は、 上述した間接圧力給水タンク 3 3によって、 O. lMPaよ りも高められる。  In S15, the jet water flow nozzle member 35 injects the jet water flow into the drain pipe by opening the water control valve 37_6 based on the above control signal, and discharges the water in the sewage horizontal pipe 23. Is forcibly drained toward the vertical pipe 24 for sewage. At this time, a jet water stream is injected at a pressure of O.lMPa in the water supply pipe 34, but the initial pressure immediately after opening the water control valve 37-6 is increased by the indirect pressure supply tank 33 described above. . Can be higher than lMPa.
そして、 S 1 6に進み、 中継ジヱット水流ノズル部材 3 6は、 上記制御信号に 基づいた水制御弁 3 7— 5の開動作により、 ジエツト水流を排水管内に噴射し、 汚水用水平管 2 3内を誘導されてきた排水を、 さらに汚水用竪管 2 4に向けて誘 導する。 これにより、 便器 1 6からの排水は、 本実施の形態のように水平管が無 勾配で設置されてあつても、 円滑に竪管まで誘導排水される。 Then, proceeding to S16, the relay jet water flow nozzle member 36 injects the jet water flow into the drain pipe by opening the water control valve 37-5 based on the control signal, The wastewater guided in the horizontal pipe for sewage 23 is further guided to the vertical pipe for sewage 24. As a result, the drainage from the toilet bowl 16 is smoothly guided to the vertical pipe even if the horizontal pipe is installed at an incline as in the present embodiment.
なお、 便器 1 6からの汚水の誘導排水については、 図 6を参照して説明した制 御方法だけでなく、 便器 1 6に電動リモート型洗浄弁式のものを採用し、 洗浄ボ タンの ON動作に連動してノズル部材 3 5， 3 6を作動させるように構成しても良 い。 具体的には、 洗浄ボタンが押されると、 便器 1 6に連結された洗浄タンク内 の洗浄水が排出され、 汚物と共に接続管 2 5— 6に排水される。 この時、 洗浄ボ タンが押されたことを示す信号が制御盤 5 0に送信されるように構成しておき、 所定のタイミングで、 ジェット水流ノズル部材 3 5及び中継ジヱット水流ノズル 部材 3 6を作動させるように、 制御盤 5 0が水制御弁 3 2— 5， 3 2 - 6の開閉 を制御するように構成すれば良い。  In addition to the control method described with reference to Fig. 6, wastewater from the toilet 16 is not only controlled as described with reference to Fig. 6, but an electric remote-type flush valve is used for the toilet 16, and the flush button is turned on. The nozzle members 35 and 36 may be operated in conjunction with the operation. Specifically, when the flush button is pressed, the flush water in the flush tank connected to the toilet bowl 16 is drained and drained to the connecting pipe 25-6 together with the waste. At this time, a signal indicating that the cleaning button is pressed is transmitted to the control panel 50, and the jet water flow nozzle member 35 and the relay jet water flow nozzle member 36 are set at a predetermined timing. The control panel 50 may be configured to control the opening and closing of the water control valves 32-5 and 32-6 so as to operate.
また、 上述した制御方法では、 便器 1 6からの排水を例にとって説明したが、 他の水回り設備 1 1〜 1 5についても、 同様に流水検知器 3 7による排水の検知 信号に基づいて、 水制御弁 3 2及び空気制御弁 4 4の開閉を行って、 ノズル部材 からジエツト水流及びジエツト気流を噴射させるように制御すれば良い。 この場 合、 噴射タイミング、 噴射時間、 圧縮空気圧、 水圧等の条件は、 各水回り設備の 特性に従って適宜決定すれば良い。  Further, in the control method described above, the drainage from the toilet bowl 16 has been described as an example, but the other plumbing facilities 11 to 15 also have the same configuration based on the detection signal of the drainage by the flowing water detector 37. The water control valve 32 and the air control valve 44 may be opened and closed to control the jetting of the jet water stream and the jet air stream from the nozzle member. In this case, conditions such as injection timing, injection time, compressed air pressure, and water pressure may be appropriately determined according to the characteristics of each plumbing system.
また、 本実施の形態に係る制御盤は、 定期排水管清掃のために、 所定の周期で ジエツト水流発生装置及びジ工ツト気流発生装置を作動させるように設定されて いる。 例えば、 一週間に一度、 12時に全てのジェット水流発生装置及びジェット 気流発生装置を一分間作動させるように設定すれば、 排水管内周面に付着した油 脂成分を洗い流して清掃を行うことができ、 排水管の詰まりを防止することもで きる。  Further, the control panel according to the present embodiment is set so as to operate the jet water flow generator and the jet air flow generator at a predetermined cycle for periodic drain pipe cleaning. For example, if all jet water flow generators and jet air flow generators are set to operate for one minute once a week and at 12:00, the oil components adhering to the inner peripheral surface of the drain pipe can be washed away and cleaned. Also, it is possible to prevent the drain pipe from being clogged.
なお、 本実施の形態に係る強制排水システムは、 新規に建物を建設する際には 、 排水管の設計時から本強制排水装置を組み込んで設計すれば良い。 さらに、 既 存の建物の排水管であっても、 ノズル部材を既存の排水管に取り付けることで、 簡単に後付けで設置可能である。 以上、 詳細に説明したように、 本実施の形態に係る強制排水装置によれば、 単 純な構成で強制的な排水が可能である。 また、 強制排水装置が故障した場合であ つても、 水平管内の排水を阻害する部材が無いので、 排水詰まりを生じることも ない。 なお、 本実施の形態では、 水平管を勾配 0° で設置しているが、 接続管から 重力排水により流れてくる排水の作用により、 ある程度竪管への排水が行われる ことになる。 When constructing a new building, the forced drainage system according to the present embodiment may be designed by incorporating the forced drainage device from the time of designing the drainage pipe. Furthermore, even a drain pipe of an existing building can be easily retrofitted by attaching the nozzle member to the existing drain pipe. As described above in detail, according to the forced drainage device according to the present embodiment, forced drainage is possible with a simple configuration. In addition, even if the forced drainage system breaks down, there is no member that hinders drainage in the horizontal pipe, so no drainage clogging occurs. In this embodiment, the horizontal pipes are installed at a gradient of 0 °, but the drainage to the vertical pipes is performed to some extent by the action of drainage flowing from the connection pipes by gravity drainage.
また、 本強制排水装置においては、 雑排水系統の中継用のジェット流体流発生 装置として、 ジェット気流発生装置を用いており、 ジェット水流を使用する場合 と比べて、 水道水を節約することができる。  In addition, this forced drainage system uses a jet airflow generation device as a jet fluid flow generation device for relaying miscellaneous drainage systems, and can save tap water compared to using a jet flow. .
なお、 本発明の実施の形態は、 上述した強制排水装置に限定されるものではな く、 本発明の趣旨を逸脱しない範囲内で適宜変更可能である。  The embodiment of the present invention is not limited to the above-described forced drainage device, and can be appropriately changed without departing from the gist of the present invention.
例えば、 ジェット水流発生装置で用いる流体として、 本実施の形態では、 水道 水を用いているが、 雨水などを溜めた雑用水を用いても良い。  For example, in the present embodiment, tap water is used as the fluid used in the jet water flow generator, but miscellaneous water containing rainwater or the like may be used.
また、 本実施の形態においては、 図 1に示すように、 水平管に設置された中継 用のジェット流体流発生装置として、 ジェット気流発生装置を用いている。 これ は、 汚水系統と比べて雑排水系統では、 通常固形物の大きさが小さく、 その数も 少ないからであるが、 排水の確実性を高めるために、 ジェット水流発生装置を使 用しても良いのは勿論である。 また、 水平管に設けられる中継用ノズル部材の個 数及び間隔は、 水平管の長さ及び圧縮流体の圧力に応じて適宜変更可能である。 さらに、 本実施の形態では、 ジェット流体流発生装置として、 ジェット水流発 生装置及びジエツト気流発生装置の双方を適宜配置しているが、 ジエツト水流発 生装置又はジェット気流発生装置の一方だけでも良い。 この場合には、 適宜、 圧 縮流体の圧力や設置間隔を、 確実に排水可能に設計する必要がある。  Further, in the present embodiment, as shown in FIG. 1, a jet airflow generator is used as a relay jet fluid flow generator installed in a horizontal pipe. This is because, in general, the size of solid matter is smaller and the number of solid matter is smaller in sewage systems than in sewage systems. Of course it is good. Also, the number and spacing of the relay nozzle members provided in the horizontal pipe can be appropriately changed according to the length of the horizontal pipe and the pressure of the compressed fluid. Further, in the present embodiment, as the jet fluid flow generator, both the jet water flow generator and the jet airflow generator are appropriately arranged, but only one of the jet water flow generator or the jet airflow generator may be used. . In this case, it is necessary to design the pressure and installation interval of the compressed fluid so that it can be drained reliably.
さらに、 本実施の形態では、水平管を勾配 0° で設置しているが、 多少の傾斜を 持って配置されていても良い。 特に、 既存の建物の排水管に本強制排水装置を後 付けする場合には、 水平管は傾斜を持って設置されている。 但し、 新規の建物の 排水管を設計する場合には、水平管の勾配 0° のほうが、設計の自由度を持った設 計が可能となり、 望ましい。 また、 本実施の形態では、 ジェット気流発生装置の流体として空気を用いてい るが、 空気以外の気体であっても良い Furthermore, in the present embodiment, the horizontal pipes are installed with a gradient of 0 °, but they may be arranged with a slight inclination. In particular, when retrofitting this forced drainage system to an existing building drainage pipe, the horizontal pipe is installed with an inclination. However, when designing drainage pipes for a new building, it is preferable to use a horizontal pipe with a gradient of 0 ° because it allows design with more design freedom. Further, in the present embodiment, air is used as the fluid of the jet airflow generator, but a gas other than air may be used.
