Description

本発明は、トラップ装置に関し、詳しくは排水トラップの封水切れによる騒音発生を未然に防止するための技術に関するものである。 The present invention relates to a trap device, and more particularly, to a technique for preventing noise generation due to a drain trap running out of water.

従来から、洗い場パンからの排水が流れる洗い場パン排水トラップと、浴槽からの排水が流れる浴槽排水トラップと、浴槽を設置する浴槽パンからの排水が流れる浴槽パン排水トラップとを備えると共に、浴槽排水トラップからの排水が流れる第1排水路と、浴槽パン排水トラップからの排水が流れる第2排水路と、洗い場パン排水トラップから排出される排水が流れる第3排水路とを合流部で合流させて共通の排水管で排水するようにしたトラップ装置が知られている(例えば、特許文献1参照)。   Conventionally, it has been provided with a washing ground pan drain trap through which drainage from the washing pan flows, a bathtub drain trap through which drainage from the bathtub flows, and a bathtub pan drain trap through which drainage from the bathtub pan where the bathtub is installed, and a bathtub drain trap The first drainage channel through which the wastewater flows from, the second drainage channel through which the drainage from the bathtub pan drainage trap flows, and the third drainage channel through which the drainage discharged from the washroom pan drainage trap flows are joined together at the junction. There is known a trap device that drains water with a drain pipe (see, for example, Patent Document 1).

ところが上記特許文献1に示された従来例では、浴槽内の大量の水を排水する場合或いは洗い場パン上の大量の水を排水する場合には、合流部に大きな負圧が発生して、排水が行なわれない排水トラップに溜められている封水が合流部側に強く引き込まれて封水切れを起こし、この場合、封水切れ状態で空気が吸い込まれる際に不快な「ゴボゴボ音」が発生するという問題があった。
特開2005−282123号公報
However, in the conventional example shown in Patent Document 1 described above, when a large amount of water in the bathtub is drained or when a large amount of water on the washing basin is drained, a large negative pressure is generated at the junction, and the drainage The water trapped in the drain trap that does not perform is strongly drawn into the confluence, causing the water to run out. In this case, an unpleasant “gobbling sound” occurs when air is sucked in when the water is shut out. There was a problem.
JP-A-2005-282123

本発明は上記の従来の問題点に鑑みて発明したものであって、通常時は空気吸入管内を封水で水密的に封止できるものでありながら、排水時における合流部の負圧発生時には空気吸入管内に空気経路が形成され、合流部で発生した負圧を低下させることができ、排水トラップの封水切れを防いで封水切れの際の騒音発生を防止できるようにしたトラップ装置を提供することを課題とするものである。 The present invention has been invented in view of the above-described conventional problems, and can normally seal the inside of the air suction pipe with water sealing while the negative pressure is generated at the merging portion during drainage. Provided is a trap device in which an air path is formed in an air suction pipe, the negative pressure generated at a merging portion can be reduced, and a drain trap is prevented from running out of sealing water, and noise generation at the time of running out of sealing water is prevented. This is a problem.

前記課題を解決するために本発明は、洗い場パン5からの排水が流れる洗い場パン排水トラップ6と、浴槽1からの排水が流れる浴槽排水トラップ2と、浴槽1を設置する浴槽パン3からの排水が流れる浴槽パン排水トラップ4とを備えると共に、浴槽排水トラップ2からの排水が流れる第1排水路7と、洗い場パン排水トラップ6から排出される排水が流れる第3排水路9とを合流部36で合流させると共に、浴槽パン排水トラップ4からの排水が流れる第2排水路8を、合流部35又は第3排水路9のいずれかに合流させて、共通の排水管で排水するようにしたトラップ装置であって、上記合流部36に接続される空気吸入管10を備え、空気吸入管10の途中に、封水を溜めるトラップ部18と、トラップ部18と合流部36との間に介在されて流出口19bが流入口19aよりも上方に配置された水溜め部19とを設け、上記空気吸入管10の吸気口25を浴槽パン排水部30に開口させると共に、該吸気口25を洗い場パン排水トラップ6の封水が切れる下限水位L1よりも高い位置で且つ浴槽パン排水部30の封水の上限水位L2よりも低い位置に配置するか、又は、上記空気吸入管10の吸気口25を洗い場パン5に開口させると共に、該吸気口25を洗い場パン排水トラップ6の封水が切れる下限水位L1よりも高い位置で且つ洗い場パン5の封水の上限水位よりも低い位置に配置したことを特徴としている。 In order to solve the above-mentioned problems, the present invention is directed to a washing basin drainage trap 6 in which drainage from the washing basin 5 flows, a bathtub drainage trap 2 in which drainage from the bathtub 1 flows, and drainage from the bathtub pan 3 in which the bathtub 1 is installed. The first drainage channel 7 through which the drainage from the bathtub drainage trap 2 flows and the third drainage channel 9 through which the drainage discharged from the washing place pan drainage trap 6 flows are joined together 36. And the second drainage channel 8 through which drainage from the bathtub pan drain trap 4 flows is merged with either the junction 35 or the third drainage channel 9 and drained through a common drain pipe. The apparatus includes an air suction pipe 10 connected to the merging portion 36, and a trap portion 18 that collects sealed water in the middle of the air suction tube 10, and between the trap portion 18 and the merging portion 36. Zaisa is in the outlet 19b is provided a water reservoir 19 disposed above the inlet 19a, causes opening of the suction port 25 of the air intake pipe 10 in a bath pan drainage unit 30, the intake port 25 It is arranged at a position higher than the lower limit water level L1 at which the sealing water of the washing ground pan drain trap 6 can be cut and lower than the upper limit water level L2 of the sealing water of the bathtub pan drainage section 30, or the intake port of the air suction pipe 10 25 is opened to the washing place pan 5 and the intake port 25 is arranged at a position higher than the lower limit water level L1 at which the sealing water of the washing place pan drain trap 6 is cut and lower than the upper limit level of the sealing water of the washing place pan 5. It is characterized by that.

このような構成とすることで、通常時は空気吸入管10の吸気口25を浴槽パン排水部30又は洗い場パン5のいずれかの封水の上限水位L2よりも低くすることで、空気吸入管10はそのトラップ部18内の封水によって水密的に封止される。一方、浴槽水の排水時に合流部36で大きな負圧が発生すると、空気吸入管10内の封水に対して引き込み力が作用して、浴槽パン排水部30又は洗い場パン5のいずれかの封水水位が空気吸入管10の吸気口25よりも低くなり、この段階で空気吸入管10の吸気口25が浴室内に開放されて、浴室内の空気が空気吸入管10に吸引される。このとき、空気吸入管10内の封水がトラップ部18から水溜め部19内に移動するが、水溜め部19の流出口19bは流入口19aよりも上方に配置されているため、流入口19aから流入した封水は流出口19bから抜け出ることができずに水溜め部19の底部に押し込められた状態で保持され、この状態で水溜め部19内には流出口19bから流入口19aに抜ける空気通路が形成され、水溜め部19から抜け出た空気が合流部36に吸引されることにより、合流部36内部に満たされた水中に吸引された空気が混入することで、合流部36の負圧が低下して洗い場パン排水トラップ6の封水切れを防止できる。またこのとき空気吸入管10の吸気口25は洗い場パン排水トラップ6の封水が切れる下限水位L1よりも高い位置に配置されているので、洗い場パン排水トラップ6の封水が切れる前に、合流部36の負圧を低下させることができ、洗い場パン排水トラップ6の封水切れによる不快な「ゴボゴボ音」の発生を防止できる。   By adopting such a configuration, the air intake pipe 10 is normally made lower than the upper limit water level L2 of the sealed water in either the bathtub pan drainage section 30 or the washing place pan 5 by the air intake pipe 10. 10 is watertightly sealed by the sealing water in the trap portion 18. On the other hand, when a large negative pressure is generated in the merging portion 36 during drainage of the bath water, a pulling force acts on the sealed water in the air suction pipe 10 to seal either the bathtub pan drainage portion 30 or the washing pan 5. The water level becomes lower than the air intake 25 of the air intake pipe 10, and at this stage, the air intake 25 of the air intake pipe 10 is opened into the bathroom, and the air in the bathroom is sucked into the air intake pipe 10. At this time, the sealed water in the air suction pipe 10 moves from the trap portion 18 into the water reservoir 19, but since the outlet 19 b of the water reservoir 19 is disposed above the inlet 19 a, The sealed water that has flowed in from 19a cannot be discharged from the outlet 19b and is held in a state where it is pushed into the bottom of the water reservoir 19, and in this state, the water in the water reservoir 19 is transferred from the outlet 19b to the inlet 19a. An air passage is formed, and the air that has escaped from the water reservoir 19 is sucked into the merging portion 36, so that the air sucked into the water filled in the merging portion 36 is mixed, so that the merging portion 36 The negative pressure is lowered, and it is possible to prevent the washing pan drain trap 6 from being closed. At this time, the air inlet 25 of the air suction pipe 10 is arranged at a position higher than the lower limit water level L1 at which the sealing water of the washing place pan drain trap 6 can be cut off. The negative pressure of the part 36 can be reduced, and the generation of unpleasant “gobbling noise” due to running out of the sealing water of the washing place pan drain trap 6 can be prevented.

また、上記浴槽排水トラップ2及び浴槽パン排水トラップ4の封水が切れる下限水位が、上記洗い場パン排水トラップ6の封水が切れる下限水位L1と同じ水位か或いはそれよりも低い水位であるのが好ましく、この場合、浴槽排水時又は洗い場排水のいずれの場合も、排水トラップの封水切れによる不快な「ゴボゴボ音」の発生を防止できるようになる。   In addition, the lower limit water level at which the sealing water of the bathtub drain trap 2 and the bathtub pan drain trap 4 is cut is the same or lower than the lower limit water level L1 at which the washing pan drain trap 6 is sealed. Preferably, in this case, it is possible to prevent an unpleasant “gobbling sound” due to running out of the sealing water of the drain trap in both cases of draining the bathtub or draining the washing place.

また、上記空気吸入管10内の封水量が上記各排水トラップ2、4、6内のそれぞれの封水量よりも少なくなるように、空気吸入管10の径を細く形成するのが好ましく、この場合、空気吸入管10内の封水量を少なくすることで、合流部36内の負圧発生時には、空気吸入管10内の封水が最も早く引き込まれて合流部36内への空気吸引が迅速に行なわれるようになる。   In addition, it is preferable that the diameter of the air suction pipe 10 is made narrow so that the amount of sealed water in the air suction pipe 10 is smaller than the amount of sealed water in each of the drain traps 2, 4, 6. By reducing the amount of sealed water in the air suction pipe 10, when negative pressure is generated in the merging portion 36, the sealed water in the air suction pipe 10 is drawn in the earliest and air suction into the merging portion 36 is quickly performed. To be done.

本発明にあっては、通常時は空気吸入管内を封水で水密的に封止できるものでありながら、合流部の負圧発生時には排水トラップの封水が切れる前に、空気吸入管内に浴室内に開放された空気経路を形成でき、合流部で発生した負圧を低減させることができる結果、排水トラップの封水切れを防いで、封水切れ状態で空気が吸い込まれる際の騒音発生を防止できるものである。   In the present invention, the inside of the air suction pipe can be sealed in a watertight manner with a sealed water in a normal state, but when a negative pressure is generated at the merging portion, a bathroom is placed in the air suction pipe before the drain trap is closed. As a result of being able to form an open air path and reducing negative pressure generated at the merging section, it prevents the drain trap from running out of seal water and prevents noise from being generated when air is sucked in when the seal is out of seal water. Is.

トラップ装置22は、図2〜図4に示すように、浴槽パン3側に固定される浴槽側トラップ本体部23と、洗い場パン5側に固定される洗い場側トラップ本体部16とを備えている。なお図3中の51はヘアキャッチャーである。   The trap apparatus 22 is provided with the bathtub side trap main-body part 23 fixed to the bathtub pan 3 side, and the washing place side trap main-body part 16 fixed to the washing place pan 5 side, as shown in FIGS. . In addition, 51 in FIG. 3 is a hair catcher.

浴槽側トラップ本体部23は、浴槽排水トラップ2の主体となるもので、上方に開口した有底筒状をしている。浴槽側トラップ本体部23の側壁には、第1排水筒部27と、第2排水筒部28と、空気吸入管10とが横方向から接続されている。空気吸入管10は一端が吸気口25となり、他端が合流部36に連通する吐出口となっている。   The bathtub-side trap body 23 is the main body of the bathtub drain trap 2 and has a bottomed cylindrical shape opened upward. A first drain tube portion 27, a second drain tube portion 28, and the air suction pipe 10 are connected to the side wall of the bathtub side trap body portion 23 from the lateral direction. One end of the air intake pipe 10 serves as an intake port 25, and the other end serves as a discharge port communicating with the merging portion 36.

浴槽側トラップ本体部23に設けられるエルボ11には、図5に示すように、第2排水筒部28に連通する第2排水口部31と、空気吸入管10の吸気口25とが設けられ、エルボ11内に挿入されて流路を仕切るエルボカバー13(図2、図4)には、第1排水筒部27に連通する排水穴50が設けられている。   As shown in FIG. 5, the elbow 11 provided in the bathtub-side trap body 23 is provided with a second drain port 31 that communicates with the second drain cylinder 28 and an inlet 25 of the air suction pipe 10. The elbow cover 13 (FIGS. 2 and 4) that is inserted into the elbow 11 to partition the flow path is provided with a drain hole 50 that communicates with the first drain cylinder portion 27.

浴槽排水口24からの排水は、排水穴50を介して第1排水筒部27内に溜められて浴槽排水トラップ2が構成される。また、浴槽パン排水部30からの排水は、第2排水口部31を介して第2排水筒部28内に溜められて浴槽パン排水トラップ4が構成される。また、浴槽パン排水部30からの排水は、空気吸入管10の吸気口25からトラップ部18内に溜められるようになっている。   Drainage from the bathtub drainage port 24 is stored in the first drainage cylinder part 27 through the drainage hole 50 to form the bathtub drainage trap 2. Moreover, the waste water from the bathtub pan drainage part 30 is stored in the 2nd drainage cylinder part 28 via the 2nd drain outlet part 31, and the bathtub pan drainage trap 4 is comprised. Further, the drainage from the bathtub pan drainage section 30 is stored in the trap section 18 from the air inlet 25 of the air suction pipe 10.

一方、洗い場側トラップ本体部16は上方に開口した有底筒状をしており、内部には洗い場パン排水トラップ6を構成する封水筒17が嵌め込まれており、この封水筒17の上端部が洗い場用排水孔20となっている。   On the other hand, the wash basin side trap main body 16 has a bottomed cylindrical shape opened upward, and a water seal cylinder 17 constituting the wash basin drain drain trap 6 is fitted inside, and the upper end portion of the water seal cylinder 17 is It is a drainage hole 20 for a washing place.

図9に示すように、洗い場側トラップ本体部16の上部外周部の片側半分に沿って前記第1排水筒部27に接続される第1排水路7が形成され、他の片側半分に沿って前記第2排水筒部28に接続される第2排水路8が形成されている。さらに洗い場側トラップ本体部16には洗い場パン排水トラップ6内の排水を排出する第3排水路9が形成されており、この第3排水路9の出口部14は第1排水路7の出口部12と連通している。これら3つの出口部12〜14は、一箇所に集まって筒状をした合流部36に連通していると共に、この合流部36に排水管(図示せず)が接続されている。これにより3つの出口部12〜14からの排水が一箇所の合流部36で合流して排水管から排出される。なお本例では3つの出口部12〜14から合流部36への排出方向(矢印イ、ロ、ハで示す方向)がほぼ平行となっている。   As shown in FIG. 9, the 1st drainage channel 7 connected to the said 1st drainage cylinder part 27 is formed along the one side half of the upper outer peripheral part of the washing place side trap main-body part 16, and along the other one side half A second drainage channel 8 connected to the second drainage cylinder portion 28 is formed. Further, a third drainage passage 9 for discharging the wastewater in the washing ground pan drain trap 6 is formed in the washing ground side trap body portion 16, and an outlet portion 14 of the third drainage passage 9 is an outlet portion of the first drainage passage 7. 12 communicates. The three outlet portions 12 to 14 are communicated with a cylindrical joining portion 36 gathered at one place, and a drain pipe (not shown) is connected to the joining portion 36. As a result, the waste water from the three outlet portions 12 to 14 is joined at one joining portion 36 and discharged from the drain pipe. In this example, the discharge directions (directions indicated by arrows A, B, and C) from the three outlet portions 12 to 14 to the merging portion 36 are substantially parallel.

図10は、浴槽側トラップ本体部23の上面外周部を覆う流路閉止部材37を示している。流路閉止部材37は中央が開口した円環状に形成されており、第1排水路7を上から覆うカバー部7aと、第2排水路8を上から覆うカバー部8aとを備えている。本例では第1排水路7を覆うカバー部7aの内面から4個のリブ38〜40が突設されている。第1、第2のリブ38は第1排水路7内に流れる排水の勢いを制限するためのものであり、必ずしも2個に限らず1個でもよい。第3のリブ39は第1排水路7の出口部12(図9(a))の真上に位置して、該出口部12を狭めて排水流量を制限するためのものであり、第4のリブ40は第1排水路7内の排水が隣接する第3排水路9内に流れ込まないようにするためのもので、第1〜第3のリブ38、39よりも下方へ大きく突出している。   FIG. 10 shows a flow path closing member 37 that covers the outer periphery of the upper surface of the bathtub-side trap body 23. The flow path closing member 37 is formed in an annular shape having an open center, and includes a cover portion 7a that covers the first drainage channel 7 from above and a cover portion 8a that covers the second drainage channel 8 from above. In this example, four ribs 38 to 40 project from the inner surface of the cover portion 7 a that covers the first drainage channel 7. The 1st, 2nd rib 38 is for restrict | limiting the momentum of the waste_water | drain which flows into the 1st drainage channel 7, It does not necessarily need to be two but may be one. The third rib 39 is located immediately above the outlet portion 12 (FIG. 9A) of the first drainage channel 7, and is used to narrow the outlet portion 12 to limit the drainage flow rate. The rib 40 is for preventing the drainage in the first drainage channel 7 from flowing into the adjacent third drainage channel 9, and protrudes more downward than the first to third ribs 38 and 39. .

ここで、本発明においては、図1に示すように、合流部36と浴槽パン3の浴槽パン排水部30とを接続する空気吸入管10を備えている。空気吸入管10の途中には、封水を溜めるトラップ部18と、トラップ部18と合流部36との間に介在されて流出口19bが流入口19aよりも上方に配置された水溜め部19とが設けられている。   Here, in this invention, as shown in FIG. 1, the air suction pipe 10 which connects the confluence | merging part 36 and the bathtub pan drainage part 30 of the bathtub pan 3 is provided. In the middle of the air suction pipe 10, a trap portion 18 for storing sealed water, and a water reservoir portion 19 interposed between the trap portion 18 and the junction portion 36 and having an outlet 19 b disposed above the inlet 19 a. And are provided.

空気吸入管10の吸気口25は、浴槽パン排水部30の封水の上限水位L2(図1)よりも低い位置に配置されており、これにより通常時は空気吸入管10のトラップ部18内に封水が溜められている。   The air inlet 25 of the air suction pipe 10 is disposed at a position lower than the upper limit water level L2 (FIG. 1) of the sealed water of the bathtub pan drainage section 30. Sealed water has been collected.

さらに空気吸入管10の吸気口25は、洗い場パン排水トラップ6の封水が切れる下限水位L1よりも高い位置に配置されており、これにより合流部36で負圧が発生したときに洗い場パン排水トラップ6の封水が切れる前に、空気吸入管10から合流部36に空気が吸引されることで、合流部36で発生した負圧を低減できるようになっている。   Further, the air inlet 25 of the air suction pipe 10 is disposed at a position higher than the lower limit water level L1 at which the sealing water of the washing place pan drain trap 6 is cut off, so that when the negative pressure is generated in the junction 36, the washing place pan drainage is performed. Before the trap 6 is sealed, air is sucked from the air suction pipe 10 to the junction 36 so that the negative pressure generated at the junction 36 can be reduced.

ここで、空気吸入管10内の封水量が各排水トラップ2、4、6内のそれぞれの封水量よりも少なくなるように、空気吸入管10の径を細く形成してある。また、空気吸入管10の水溜め部19は、トラップ部18よりも上方位置に設置されると共にトラップ部18内の容積よりも大きな容積のチャンバーで構成されている。また水溜め部19の流出口19bが流入口19aよりも上方に位置するように、水溜め部19の対角方向に流出口19bと流入口19aとを配置してあり、これにより流入口19aから流入する封水を流出口19bから流出させずに、流入口19aから流入する空気のみを流出口19bから流出させるようにしている。図1の例では、流入口19aと流出口19bとを結ぶ対角線よりも下方領域に封水を一時的に逃がすためのタンク部とし、上方領域を空気経路としている。さらに流入口19a近傍には上下二股形状に分岐した分岐通路41が設けられ、下側分岐路41aを下方領域に向け、上側分岐路41bを上方領域に向けることで、水溜め部19内で封水と空気とがスムーズに分流されるようにしている。   Here, the diameter of the air suction pipe 10 is made thin so that the amount of sealed water in the air suction pipe 10 is smaller than the amount of sealed water in each of the drain traps 2, 4, 6. Further, the water reservoir 19 of the air suction pipe 10 is installed at a position higher than the trap part 18 and is constituted by a chamber having a volume larger than the volume in the trap part 18. In addition, the outlet 19b and the inlet 19a are arranged diagonally to the water reservoir 19 so that the outlet 19b of the water reservoir 19 is located above the inlet 19a. However, only the air flowing in from the inflow port 19a is allowed to flow out of the outflow port 19b without flowing out the sealed water flowing in from the outflow port 19b. In the example of FIG. 1, a tank portion for allowing the sealed water to escape temporarily in a region below the diagonal line connecting the inlet 19 a and the outlet 19 b is used, and the upper region is an air path. Further, a branch passage 41 branched in an up-and-down bifurcated shape is provided in the vicinity of the inflow port 19a. The lower branch passage 41a faces the lower region and the upper branch passage 41b faces the upper region. Water and air are diverted smoothly.

上記水溜め部19の流出口19bは、合流部36よりも上方位置に配置した空気吐出管26を介して合流部36の天井面に開放されている。これにより、合流部36から排水管へと排出される水が空気吸入管10内部に逆流するのを防止しながら、合流部36内に発生する負圧によって空気吸入管10からの空気吸引が可能となっている。   The outlet 19 b of the water reservoir 19 is opened to the ceiling surface of the merging portion 36 via an air discharge pipe 26 disposed at a position higher than the merging portion 36. As a result, it is possible to suck air from the air suction pipe 10 by the negative pressure generated in the merging section 36 while preventing the water discharged from the merging section 36 from flowing back into the air suction pipe 10. It has become.

W in FIG. 8 is a sealed water pushed into the tank pipe 45, and M is a flow direction of air passing thereover. The components of the air intake pipe 10 are not limited to those shown in FIGS.

次に排水動作を説明する。   Next, the draining operation will be described.

通常時は、図11(a)、(b)のように浴槽パン排水部30内の封水の上限水位L2が空気吸入管10の吸気口25よりも高い水位にあるため、空気吸入管10の吸気口25は浴室内に開放されず、空気吸入管10のトラップ部18内部に溜められた封水により水密的に封止されている。なお排水トラップ2、4、6も同様に封水で水密的に封止されている。   During normal times, as shown in FIGS. 11A and 11B, the upper limit water level L2 of the sealed water in the bathtub pan drainage 30 is higher than the intake port 25 of the air intake pipe 10, and therefore the air intake pipe 10 The air intake 25 is not opened in the bathroom, but is sealed watertight with a water seal accumulated in the trap portion 18 of the air intake pipe 10. The drain traps 2, 4, and 6 are similarly sealed in a watertight manner with sealed water.

先ず、浴槽排水を行なう場合を図11〜図13を参照して説明する。図11(c)のように浴槽排水時に浴槽排水トラップ2から第1排水路7を経て合流部36に大量の浴槽水が排水されると、合流部36に大きな負圧が発生する。これにより、浴槽パン排水トラップ4内、洗い場パン排水トラップ6内、空気吸入管10内のそれぞれの封水に対して引き込み力が作用する。このとき、図12(a)→(b)のように浴槽パン排水部30の封水高さが空気吸入管10の吸気口25よりも低い水位L3(<L2)まで下がると、この段階で空気吸入管10の吸気口25が浴室内に開放されて、空気吸入管10の吸気口25から浴室内の空気の吸引が開始される。またこのとき、空気吸入管10の径を細くして空気吸入管10内の封水量を浴槽排水トラップ2の封水量よりも少なくしているので、空気吸入管10内の封水が早く引き込まれるようになり、その封水がトラップ部18から水溜め部19へ移動する。ここで、水溜め部19の流出口19bは流入口19aよりも上方に配置されているため、流入口19aから流入した封水は流出口19bから抜け出ることができずに水溜め部19の底部に押し込められた状態(図12(c)の状態)で保持され、この状態で、水溜め部19内には流出口19bから流入口19aに抜ける空気通路が形成され、水溜め部19から抜け出た空気が空気吐出管26を通って合流部36の天井面から吸引される。この吸引された空気が合流部36内部に満たされた水中に混入することにより、合流部36の負圧が低下する。つまり、空気吐出管26から合流部36内に空気が吸引され続けることによって、合流部36の負圧が継続して低下するようになり、洗い場パン排水トラップ6の封水切れを防止する。またこのとき、空気吸入管10の吸気口25は洗い場パン排水トラップ6の封水が切れる下限水位L1よりも高い位置に配置されているので、洗い場パン排水トラップ6の封水が切れる前に、合流部36の負圧を低下できるものであり、この結果、洗い場パン排水トラップ6の封水切れを防いで、封水切れ状態で空気が吸い込まれる際の不快な「ゴボゴボ音」の発生をなくすことができる。また本例では、浴槽パン排水トラップ4の封水が切れる下限水位が、洗い場パン排水トラップ6の封水が切れる下限水位L1と同じ水位かそれよりも低い水位となっているので、浴槽パン排水トラップ4の封水切れによる騒音発生も防止できる。   First, the case where bathtub drainage is performed will be described with reference to FIGS. When a large amount of bathtub water is drained from the bathtub drain trap 2 to the junction 36 via the first drainage channel 7 during drainage of the bathtub as shown in FIG. 11C, a large negative pressure is generated in the junction 36. Thereby, a drawing-in force acts on each of the sealed water in the bathtub pan drain trap 4, the washing place pan drain trap 6, and the air suction pipe 10. At this time, when the sealing water height of the bathtub pan drainage portion 30 is lowered to the water level L3 (<L2) lower than the intake port 25 of the air intake pipe 10 as shown in FIGS. The air inlet 25 of the air suction pipe 10 is opened into the bathroom, and the suction of air in the bathroom is started from the air inlet 25 of the air suction pipe 10. At this time, since the diameter of the air suction pipe 10 is reduced so that the amount of sealed water in the air suction pipe 10 is smaller than the amount of sealed water in the bathtub drain trap 2, the sealed water in the air suction pipe 10 is quickly drawn. Thus, the sealed water moves from the trap portion 18 to the water reservoir portion 19. Here, since the outlet 19b of the water reservoir 19 is disposed above the inlet 19a, the sealed water flowing in from the inlet 19a cannot escape from the outlet 19b, and the bottom of the water reservoir 19 is reached. In this state, an air passage extending from the outlet 19b to the inlet 19a is formed in the water reservoir 19 so as to escape from the water reservoir 19. Air is sucked from the ceiling surface of the junction 36 through the air discharge pipe 26. The sucked air is mixed into the water filled in the merging portion 36, whereby the negative pressure of the merging portion 36 is reduced. That is, as air continues to be sucked into the merging portion 36 from the air discharge pipe 26, the negative pressure of the merging portion 36 is continuously reduced, and the washing place pan drain trap 6 is prevented from running out of sealed water. At this time, the air inlet 25 of the air suction pipe 10 is disposed at a position higher than the lower limit water level L1 at which the sealing water of the washing place pan drain trap 6 is cut off. As a result, the negative pressure of the junction 36 can be reduced, and as a result, the washing pan drain trap 6 can be prevented from running out of sealing water, and the generation of unpleasant “gobbling noises” when air is sucked in when the sealing water runs out. it can. Moreover, in this example, since the lower limit water level at which the sealing water of the bathtub pan drain trap 4 is cut is the same level as the lower limit water level L1 at which the sealing water of the washing place pan drain trap 6 is cut or lower, the bathtub pan drainage. It is possible to prevent noise from being generated due to the trap 4 running out of water.

その後、浴槽排水が完了すると、合流部36が正圧状態に戻ることにより空気吸入管10からの空気吸引が終了する。これにより図13(a)→(b)→(c)のように、水溜め部19に一時的に溜められていた封水が自然落下により水溜め部19の流入口19aからトラップ部18へと戻るので空気吸入管10は元の封止状態に復帰する。従って、浴槽排水後に空気吸入管10の封水切れを起こすこともない。   Then, when bathtub drainage is completed, the air suction from the air suction pipe 10 is completed by returning the junction 36 to the positive pressure state. As a result, as shown in FIGS. 13 (a) → (b) → (c), the sealed water temporarily stored in the water reservoir 19 is naturally dropped from the inlet 19a of the water reservoir 19 to the trap 18 due to natural fall. Therefore, the air suction pipe 10 returns to the original sealed state. Therefore, the air suction pipe 10 does not run out of water after the bathtub drains.

一方、洗い場排水の場合を図14〜図16を参照して説明する。図14(a)は通常時を示し、洗い場パン5上に排水が多量に溜まると、図14(b)→(c)のように洗い場排水口の真下に位置する洗い場パン排水トラップ6内に排水され、さらに第3排水路9を経て合流部36から排水管へと排出される。このとき排水が勢いよく流れることにより、合流部36に大きな負圧が発生して、浴槽排水トラップ2側の第1排水路7内、浴槽パン排水トラップ4側の第2排水路8内、空気吸入管10内のそれぞれの封水に対して引き込み力が作用するが、前記浴槽排水の場合と同様、浴槽排水トラップ2及び浴槽パン排水トラップ4の封水が切れる前の段階で、図15(a)のように浴槽パン排水部30内の封水高さが空気吸入管10の吸気口25よりも低い水位L3まで下がった段階で、空気吸入管10の吸気口25が浴室内に開放されて空気吸引が開始されることで、図15(b)→(c)のように水溜め部19内に封水を押し込めた状態で空気吸入管10内に空気経路が形成され、これにより、空気吸入管10から吸引された空気が合流部36内部に満たされた水中に混入することにより、合流部36の負圧が継続して低下するようになり、この結果、浴槽排水トラップ2及び浴槽パン排水トラップ4の封水切れを防止できるものであり、また、排水完了後は、図16(a)→(b)→(c)の順に空気吸入管10内が封水にて水密的に封止された元の状態に復帰するものである。   On the other hand, the case of washroom drainage will be described with reference to FIGS. FIG. 14 (a) shows a normal time, and when a large amount of drainage accumulates on the washing basin pan 5, as shown in FIG. 14 (b) → (c), the washing basin drainage trap 6 located just below the washing basin drainage port. It is drained and further discharged from the junction 36 to the drain through the third drainage channel 9. At this time, the drainage flows vigorously, so that a large negative pressure is generated in the joining portion 36, the first drainage channel 7 on the bathtub drain trap 2 side, the second drain channel 8 on the bathtub pan drain trap 4 side, air Although a pulling force acts on each sealed water in the suction pipe 10, as in the case of the bathtub drainage, in a stage before the sealed water of the bathtub drain trap 2 and the bathtub pan drain trap 4 is cut, FIG. As shown in a), when the height of the sealed water in the bathtub pan drainage 30 is lowered to the water level L3 lower than the air inlet 25 of the air inlet pipe 10, the air inlet 25 of the air inlet pipe 10 is opened into the bathroom. When the air suction is started, an air path is formed in the air suction pipe 10 in a state where the sealed water is pushed into the water reservoir 19 as shown in FIG. 15 (b) → (c). Air sucked from the air suction pipe 10 is in the junction 36. The negative pressure of the merging portion 36 is continuously reduced by mixing in the water filled with water, and as a result, the bathtub drain trap 2 and the bathtub pan drain trap 4 can be prevented from running out of sealed water, Further, after the drainage is completed, the air suction pipe 10 is restored to the original state in which the inside of the air suction pipe 10 is sealed in a watertight manner in the order of FIGS. 16 (a) → (b) → (c).

しかして、通常時は空気吸入管10内を封水で水密的に封止できるものでありながら、排水時に合流部36に大きな負圧が発生した時は空気吸入管10内に空気経路が形成されて、合流部で発生した負圧の低下によって封水切れに起因する騒音防止を図ることができる利点がある。   Thus, the air intake pipe 10 can be sealed in a watertight manner under normal conditions, but an air path is formed in the air intake pipe 10 when a large negative pressure is generated in the junction 36 during drainage. In addition, there is an advantage that noise caused by running out of the sealed water can be prevented by lowering the negative pressure generated at the junction.

しかも排水完了後は、空気吸入管10の水溜め部19内に保持されていた封水がトラップ部18に自然落下して空気吸入管10が直ちに封水にて水密的に封止された状態に復帰するので、排水後の空気吸入管10の封水切れを防止できる利点がある。   In addition, after the drainage is completed, the sealed water held in the water reservoir 19 of the air suction pipe 10 naturally falls into the trap part 18 and the air suction pipe 10 is immediately sealed in a watertight manner with the sealed water. Therefore, there is an advantage that it is possible to prevent the air suction pipe 10 from being drained after draining.

また本例では、空気吸入管10の径を、空気吸入管10内の封水量が各排水路7〜9内のそれぞれの封水量よりも少なくなるように、細く形成したので、合流部36内の負圧発生時には、空気吸入管10内の封水が最も早く引き込まれて合流部36内への空気吸引が迅速に行なわれる利点がある。   Further, in this example, the diameter of the air suction pipe 10 is made narrow so that the amount of sealed water in the air suction pipe 10 is smaller than the amount of sealed water in each of the drainage channels 7 to 9. When the negative pressure is generated, there is an advantage that the sealed water in the air suction pipe 10 is drawn in the earliest and the air suction into the merging portion 36 is performed quickly.

また、水溜め部19をトラップ部18の容積よりも大きな容積のチャンバーで構成すると共に、流出口19bを流入口19aよりも上方に配置したことにより、トラップ部18からの封水を水溜め部19内の下方領域に漏れなく押し込めて保持しながら、水溜め部19の上方領域に空気経路を容易に確保できると共に、この水溜め部19内を通過する空気は封水と干渉しないため、空気の引き込みが抵抗なくスムーズに行なわれる利点がある。   In addition, the water reservoir 19 is formed of a chamber having a volume larger than the volume of the trap 18 and the outlet 19b is disposed above the inlet 19a, so that the sealed water from the trap 18 is stored in the water reservoir. The air path can be easily secured in the upper region of the water reservoir 19 while being pushed into the lower region in the air without leaking, and the air passing through the water reservoir 19 does not interfere with the sealed water. There is an advantage that the pull-in is smoothly performed without resistance.

さらに、浴槽排水トラップ2及び浴槽パン排水トラップ4の封水が切れる下限水位が、洗い場パン排水トラップ6の封水が切れる下限水位L1と同じ水位か或いはそれよりも低い水位としているので、空気吸入管10の吸気口25は、すべての排水トラップ2、4、6の封水が切れる下限水位よりもそれぞれ高く配置されることとなり、浴槽水の排水時には洗い場パン排水トラップ6及び浴槽パン排水トラップ4の封水切れをそれぞれ防止でき、一方、洗い場パン5の排水時には浴槽排水トラップ2及び浴槽パン排水トラップ4の封水切れをそれぞれ防止できる利点もある。   Furthermore, since the lower limit water level at which the sealing water of the bathtub drain trap 2 and the bathtub pan drain trap 4 is cut is the same as or lower than the lower limit water level L1 at which the sealing pan drain trap 6 is sealed, air suction is performed. The inlet 25 of the pipe 10 is arranged higher than the lower limit water level at which all the drain traps 2, 4, 6 can be sealed, and when the bathtub water is drained, the washing place pan drain trap 6 and the bathtub pan drain trap 4. On the other hand, there is also an advantage that when the washing pan 5 is drained, the bathtub drain trap 2 and the bathtub pan drain trap 4 can each be prevented from being sealed.

なお、前記実施形態では、水溜め部19内の流入口19a近傍に上下二股形状に分岐した分岐通路41を設けて封水と空気とを分流させる構造としたが、分岐通路41は省略可能である。この場合、水溜め部19の流入口19aにおいて空気の侵入方向と封水の浸入方向とが同じとなるが、空気より重い封水は水溜め部19の下方領域に向かって移動し、空気はその上方領域に向かって移動することから、水溜め部19内で空気と封水との混在を防止でき、空気のスムーズな引き込み効果が得られる。   In the above-described embodiment, the branch passage 41 is provided in the vicinity of the inflow port 19a in the water reservoir 19 so as to branch the seal water and the air into a bifurcated shape. However, the branch passage 41 can be omitted. is there. In this case, the intrusion direction of air and the intrusion direction of the sealed water at the inlet 19a of the water reservoir 19 are the same, but the sealed water heavier than air moves toward the lower region of the water reservoir 19 and the air Since it moves toward the upper area | region, mixing of air and sealing water can be prevented in the water reservoir 19, and the smooth air drawing-in effect can be obtained.

図17〜図19は他の排水構造の一例である。図17は、浴槽パン3に浴槽パン排水部30とは別の排水口を設け、この別の排水口に空気吸入管10の吸気口25を接続したものであり、他の構成は図1と同様である。図18は、空気吸入管10の吸気口25を洗い場パン排水トラップ6内部に挿入して、吸気口25を洗い場パン排水トラップ6の封水が切れる下限水位よりも高い位置で且つ洗い場パン排水トラップ6の封水の上限水位よりも低い位置に配置したものであり、他の構成は図1と同様である。図19は、浴槽パン排水トラップ4の第2排水路8を洗い場パン排水トラップ6の第3排水路9に合流させ、この第3排水路9と浴槽排水トラップ2の第1排水路7とを合流部36で合流させたものであり、他の構成は図1と同様である。これら図17〜図19のいずれの排水構造においても、前記実施形態と同様に、通常時は空気吸入管10内を封水で水密的に封止できるものでありながら、排水時には排水トラップ2(4,6)の封水切れによる騒音発生を防止できる効果が得られるものである。   17 to 19 are examples of other drainage structures.
