Description

本発明は、排水器の取付構造に関し、排水器の取り付け作業を簡易に行うことができる排水器の取付構造に関するものである。 The present invention relates to a drainage device mounting structure, and relates to a drainage device mounting structure capable of easily performing drainage device mounting work.

従来より、浴槽、洗面台、流し台、ショーケース等の排水機器の内部に生じた排水を処理するため、槽体の底面等に排水口を設けた排水器を取り付け、この排水器の排水口から配管部材を介し、下水側に排水を排出する方法が広く知られている。
以下に、この排水器の一例を説明する。
特許文献１に記載の排水器は、商品棚上を低温に維持しつつ商品の陳列を行う、低温ショーケースの結露水の排水を行う排水器であって、
低温ショーケースの底面に設けられた取付口と、
有底円筒形状であって上方の開口の周縁に備えられたフランジ部、側面の下方に備えた雄ねじ、底面部分に底面から屈曲して側方に向かう排出口、から構成される排水器と、
排水器の雄ねじと螺合する雌ねじを備えたリング状のナット部材と、
排出口に備えられる、封水式のトラップ機能を生じさせるトラップ部材と、
から構成される。ここで、「トラップ機能」とは、上流から下流側への排水は維持しつつ、下水側から臭気や害虫類が屋内側に逆流することを防止する機能である。「封水式のトラップ機能」の場合、排水の流路上に、封水と呼ばれる排水の溜まり部分を形成し、この溜まり部分によって、排水の流路の少なくとも一部が常に満水状態となることで、この満水部分から上流へ臭気や害虫類の逆流を防止する機能を示すものである。
上記のように構成された排水器は、以下のような手順にて、低温ショーケースの底面に設けられた取付口に取り付けられて、低温ショーケースに施工される。
まず、低温ショーケースの底面に設けられた取付口に、排水器を上方から挿入し、取付口周縁の上面に、排水器のフランジ部下面を当接させる。
次に、ナット部材の上面に水密的な接続を行う為、リング状のパッキングを配置した上で、排水器の雄ねじと、ナット部材の雌ねじを螺合させる。螺合が充分に進むと、排水器のフランジ部下面と、ナット部材の上面とで、取付口周縁を上下方向に強く挟持するため、排水器が取付口に接続固定される。更に排水器の外側から排出口に床下配管を接続し、また排水器の内側から排出口にトラップ部を配置して、排水器の低温ショーケースへの施工が完了する。
低温ショーケースを使用する際に、低温ショーケースに収納した品物からのドリップや、低温ショーケースの冷却機器によって冷やされた空気からの結露水が発生すると、これらドリップ・結露水等の排水は、最終的に低温ショーケースの底面にある排水口まで流下し、排水口から、排水器内部、排出口に配置されたトラップ部材、を通過し、最終的に床下配管から下水側に排出される。
また、この時、排出口内であって、トラップ部材によって形成された流路の一部において封水を形成し、臭気や害虫類の屋内側への逆流を防止している。
特開２００７−２１５７９９ Conventionally, in order to treat the drainage generated inside drainage equipment such as bathtubs, wash basins, sinks, and showcases, a drainage device with a drainage port is attached to the bottom of the tank body, etc., and from the drainage port of this drainage device. A method of discharging wastewater to the sewage side via a piping member is widely known.
An example of this drainage device will be described below.
The drainage device described in Patent Document 1 is a drainage device that drains condensed water from a low-temperature showcase, which displays products while keeping the product shelf at a low temperature.
With the mounting port provided on the bottom of the low temperature showcase,
A drainage device that has a bottomed cylindrical shape and is composed of a flange portion provided on the periphery of the upper opening, a male screw provided on the lower side surface, and a drainage port that bends from the bottom surface to the side on the bottom surface.
A ring-shaped nut member with a female screw that screwes into the male screw of the drainage device,
A trap member provided at the outlet that creates a water-sealing trap function,
Consists of. Here, the "trap function" is a function of preventing odors and pests from flowing back to the indoor side from the sewage side while maintaining drainage from the upstream side to the downstream side. In the case of the "water-sealing trap function", a drainage pool called "sealing water" is formed on the drainage channel, and at least a part of the drainage channel is always filled with water by this pool. , It shows the function of preventing the backflow of odors and pests from this filled part to the upstream.
The drainage device configured as described above is attached to the attachment port provided on the bottom surface of the low temperature showcase by the following procedure, and is installed in the low temperature showcase.
First, the drainage device is inserted from above into the mounting port provided on the bottom surface of the low temperature showcase, and the lower surface of the flange portion of the drainage device is brought into contact with the upper surface of the peripheral edge of the mounting port.
Next, in order to make a watertight connection on the upper surface of the nut member, a ring-shaped packing is arranged, and then the male screw of the drainage device and the female screw of the nut member are screwed together. When the screwing is sufficiently advanced, the lower surface of the flange portion of the drainer and the upper surface of the nut member strongly hold the peripheral edge of the mounting port in the vertical direction, so that the drainer is connected and fixed to the mounting port. Furthermore, the underfloor piping is connected from the outside of the drainage device to the discharge port, and the trap portion is arranged from the inside of the drainage device to the discharge port to complete the construction of the drainage device on the low temperature showcase.
When using a low-temperature showcase, if drip from the items stored in the low-temperature showcase or dew condensation water from the air cooled by the cooling equipment of the low-temperature showcase is generated, the drainage of these drip and dew water will be removed. Finally, it flows down to the drainage port on the bottom of the low temperature showcase, passes through the drainage port, the inside of the drainage device, and the trap member arranged at the discharge port, and finally is discharged from the underfloor pipe to the sewage side.
Further, at this time, a sealing water is formed in a part of the flow path formed by the trap member in the discharge port to prevent odors and pests from flowing back to the indoor side.
JP-A-2007-215799

上記のように構成した、特許文献１に記載の排水器において、排水器を低温ショーケース等に設けられた取付口に取り付ける作業は、ナット部材を排水器に螺合させることで行われる。このため、取り付け時には、雄ねじを備えた排水器か、雌ねじを備えたナット部材の一方を固定し、他方を回転させて螺合を行う必要がある。ところが、ナット部材は底面の上側には露出しないため、ナット部材を固定または回転させる作業は、取付口を設けた底面の上側からのみの作業では不可能であり、少なくとも底面の下側からナット部材に作業を行う必要がある。
底面の下側からナット部材に作業を行いつつ、取付口を設けた底面の上側から排水器への作業を行う為には、作業者が片手でナット部材に作業を行いつつ、底面を迂回してもう一方の手で排水器に作業を行うか、又は作業者を二名用意するなど、取付口の上下から底面を迂回して作業を行う必要があり、取り付け作業は困難なものとなる。
また、排水器とナット部材の両方に対して、取付口を設けた底面の下側から作業を行う場合は、上記のような底面を迂回する必要は無くなるが、浴槽やショーケース等の機器の底面と、機器が設置される床面との間は狭く、この狭い部分において、排水器とナット部材の、一方を固定し、他方を回転させる、という作業はやはり困難なものとなる。
また、上記特許文献１に記載の排水器では、排水器の取り付け完了後には、排水器の方向を調整することができなかった。上記のように、排出口が排水器の側面方向を向いて設けられている場合、接続される床下配管など、下流側の配管の位置や方向に合わせて、排出口の方向に向ける必要がある。しかしながら、上記特許文献１に記載の従来の排水器の場合、排水器のフランジ部とナット部材とを螺合させ、取付口の周縁を強く挟持することで取り付けを行うと共に、間に配置したパッキングを上下方向から押圧して水密を確保している。このため、排水器の取り付け完了後に排水器を回転させて方向を調整しようとしても、排水器が強く取付口周縁に当接して回転を行うことができなかった。また、仮に排水器が回転可能な程度に螺合が弱ければ、パッキングの押圧が不十分な場合があり、漏水が発生する恐れがあった。
本発明は上記問題点に鑑み発明されたものであって、取り付け作業が容易で、また施工完了後であっても、漏水なく方向の調整が可能な排水器の取付構造を提供するものである。 In the drainage device described in Patent Document 1 configured as described above, the work of attaching the drainage device to the attachment port provided in the low temperature showcase or the like is performed by screwing the nut member into the drainage device. Therefore, at the time of installation, it is necessary to fix one of the drainage device having a male screw or the nut member having a female screw and rotate the other to perform screwing. However, since the nut member is not exposed on the upper side of the bottom surface, the work of fixing or rotating the nut member cannot be performed only from the upper side of the bottom surface provided with the mounting port, and the nut member is at least from the lower side of the bottom surface. Need to work on.
In order to work on the nut member from the lower side of the bottom surface and work on the drainage device from the upper side of the bottom surface provided with the mounting port, the operator bypasses the bottom surface while working on the nut member with one hand. It is necessary to work on the drainage device with the other hand, or to prepare two workers, and to bypass the bottom surface from the top and bottom of the mounting port, which makes the mounting work difficult.
In addition, when working from the lower side of the bottom surface provided with the mounting port for both the drainage device and the nut member, it is not necessary to bypass the bottom surface as described above, but for equipment such as bathtubs and showcases. The space between the bottom surface and the floor surface on which the equipment is installed is narrow, and in this narrow portion, the work of fixing one of the drainage device and the nut member and rotating the other is still difficult.
Further, in the drainage device described in Patent Document 1, the direction of the drainage device cannot be adjusted after the installation of the drainage device is completed. As described above, when the discharge port is provided facing the side surface of the drainage device, it is necessary to face the direction of the discharge port according to the position and direction of the pipe on the downstream side such as the connected underfloor pipe. .. However, in the case of the conventional drainage device described in Patent Document 1, the flange portion of the drainage device and the nut member are screwed together, and the peripheral edge of the mounting port is strongly sandwiched for mounting, and the packing arranged between them. Is pressed from above and below to ensure watertightness. Therefore, even if an attempt is made to rotate the drainage device to adjust the direction after the installation of the drainage device is completed, the drainage device strongly abuts on the periphery of the mounting port and cannot rotate. Further, if the drainage device is loosely screwed to the extent that it can rotate, the packing may be pressed insufficiently, and water leakage may occur.
The present invention has been invented in view of the above problems, and provides a drainage device mounting structure that is easy to mount and can adjust the direction without water leakage even after the construction is completed. ..

上記のように構成された本実施例の排水器２を施工する場合、以下のような手順にて施工を行う。
まず、低温ショーケースＳＣの底面Ｂであって、取付口１ａの下方から、排水器２を、係合爪３を上側（取付口１ａ側）に向けて挿入する。排水器２を取付口１ａに挿入すると、係合爪３の爪部３ｂが、段部１ｂの内側面を通過する際に、一旦リブ部３ａが樹脂弾性により内周側（内側）に撓むことで縮径し、更に上昇させることで、爪部３ｂが段部１ｂを超えて段部１ｂの上方に乗り上げることで段部１ｂが係合爪３と係合する。
この爪部３ｂが段部１ｂを超えて段部１ｂの上方に乗り上げた状態では、排水器２の鍔部２ｂ上面が取付口１ａ下面とほぼ当接した状態となり（鍔部２ｂ上面と取付口１ａ下面との間に若干の隙間が生じる場合があるが、後述するように何ら支障はない）、排水器２は、係合爪３のリブ部３ａが内周側に撓まない限り、取付口１ａに対し、回動は可能であるが、抜脱することも、また上下動することもない状態となる。この状態は、排水器２が取付口１ａに取り付けられてなるが、係合爪３の係合の解除が容易で、排水器２としての実際の使用に耐えられるほど確実な取り付けが行われていないため、「仮止め状態」と呼ばれる。
この仮止め状態より、低温ショーケースＳＣの底面Ｂに対し上方から、排水器２の上方の受入部２ａに、排水栓５を挿入する。この際は、排水栓５を受入部２ａに挿入して回転させることで、排水栓５の雄ねじ部７ｂと受入部２ａの雌ねじ部７ａとが螺合し、排水器２に排水栓５が抜脱不可能に接続される。
この排水栓５が排水器２の受入部２ａに接続された状態では、係合爪３のリブ片に排水栓５の外側面が当接した状態、又は若干の隙間を有するものの、爪部３ｂが段部１ｂから抜脱するほどに内周側に撓む前に、排水栓５の外側面に当接してそれ以上内周側に撓むことが不可能な状態となっており、排水器２が取付口１ａから抜脱することは不可能となっている。
次に、排水器２の排出口２ｄに下流側の排水配管を接続する。この際には、接着剤などを利用し、又はネジとパッキングによる水密的な接続を利用し、漏水が生じないように確実に接続を行う。また、この接続の際に、排水器２の排出口２ｄが、床下配管の接続に適切な方向を向いていない場合には、排水器２を取付口１ａに対して回転させ、方向の調整を行う。本発明では、排水器２が取付口１ａから抜脱しない理由は、従来例のように、取付口１ａ周縁を上下に締め付けることで面同士が強く当接し、回動も不可能なように固定されているためではなく、係合爪３が内周側に撓むことが不可能となったため、排水器２の取付口１ａからの抜脱が不可能となったためであり、面同士が、回動が不可能なほど強く当接している箇所は無い。凹部２ｃに配置されているＯリングＯは、排水器２の凹部２ｃと取付口１ａの間であって、水密を維持できる程度には強い、面による当接を、排水器２また取付口１ａの間に生じているが、排水器２（又は排水器２の凹部２ｃ）と取付口１ａの側面方向の隙間の幅と、その間に配置されるＯリングＯの寸法は、設計により、設計者が希望する一定の幅や大きさを常に確保・維持できるため、「水密を確保しつつ、回転も可能な程度の当接を生じる、排水器２と取付口１ａの間の幅、及びＯリングＯの寸法」に各部材を設計することで、排水器２の取付口１ａへの取り付け後であっても、排水器２を取付口１ａに対して回動可能とし、排水器２の排出口２ｄを配管接続に都合の良い方向に向けて調整することが可能である。
次に、排水栓５内部の突起部５ｂに、防臭筒８の嵌合溝８ｂを嵌合させて接続を行う。この際には、排水口４内に防臭筒８を挿入した後、防臭筒８を螺合の締め付け方向に回転させることで、嵌合溝８ｂと突起部５ｂが嵌合して、排水口４内に嵌合固定される。また、この防臭筒８の回転作業は、防臭筒８の取っ手部８ａを把持して行うため、排水栓５のような凹凸の少ない部材を把持して回転させるよりも容易に回転をさせることができ、また回転させる際には作業者の力を作用させやすい。このため、防臭筒８の回転を進めると、排水栓５が防臭筒８と共に一体となって回転し、排水器２と排水栓５の螺合が更に追加して行われる場合がある。この場合は、排水器２と排水栓５の接続がより強固となり、排水器２の接続はより好適に行われる。 When constructing the drainage device 2 of the present embodiment configured as described above, the procedure is as follows.
First, the drainage device 2 is inserted from below the mounting port 1a on the bottom surface B of the low temperature showcase SC with the engaging claw 3 facing upward (mounting port 1a side). When the drainer 2 is inserted into the mounting port 1a, when the claw portion 3b of the engaging claw 3 passes through the inner surface of the step portion 1b, the rib portion 3a temporarily bends to the inner peripheral side (inside) due to resin elasticity. By reducing the diameter and further raising the diameter, the claw portion 3b goes over the step portion 1b and rides on the step portion 1b, so that the step portion 1b engages with the engaging claw 3.
When the claw portion 3b goes over the step portion 1b and rides above the step portion 1b, the upper surface of the flange portion 2b of the drainer 2 is in a state of being substantially in contact with the lower surface of the mounting port 1a (the upper surface of the flange portion 2b and the mounting port). There may be a slight gap between the 1a and the lower surface, but there is no problem as described later), but the drainer 2 is attached unless the rib portion 3a of the engaging claw 3 bends to the inner peripheral side. Although it can rotate with respect to the mouth 1a, it does not come off or move up and down. In this state, the drainage device 2 is attached to the attachment port 1a, but the engagement of the engaging claw 3 is easily disengaged, and the drainage device 2 is securely attached so as to withstand the actual use as the drainage device 2. Since there is no such thing, it is called a "temporary fixing state".
From this temporarily fixed state, the drain plug 5 is inserted into the receiving portion 2a above the drain device 2 from above with respect to the bottom surface B of the low temperature showcase SC. At this time, by inserting the drain plug 5 into the receiving portion 2a and rotating it, the male threaded portion 7b of the drain plug 5 and the female threaded portion 7a of the receiving portion 2a are screwed together, and the drain plug 5 is pulled out from the drainage device 2. Connected inseparably.
When the drain plug 5 is connected to the receiving portion 2a of the drainer 2, the outer surface of the drain plug 5 is in contact with the rib piece of the engaging claw 3, or the claw portion 3b has a slight gap. Before it bends to the inner peripheral side enough to be pulled out from the step portion 1b, it comes into contact with the outer surface of the drain plug 5 and cannot bend further to the inner peripheral side. It is impossible for 2 to be removed from the mounting port 1a.
Next, the drainage pipe on the downstream side is connected to the discharge port 2d of the drainage device 2. In this case, use an adhesive or a watertight connection with screws and packing to ensure the connection so that water leakage does not occur. Further, at the time of this connection, if the drain port 2d of the drain device 2 does not face an appropriate direction for connecting the underfloor piping, the drain device 2 is rotated with respect to the mounting port 1a to adjust the direction. Do. In the present invention, the reason why the drainage device 2 does not come off from the mounting port 1a is that the surfaces are strongly in contact with each other by tightening the peripheral edge of the mounting port 1a up and down as in the conventional example, and the drainage device 2 is fixed so that it cannot rotate. This is not because the engaging claws 3 are bent toward the inner circumference side, but because it is impossible to remove the drainage device 2 from the attachment port 1a. There is no place where it is in contact so strongly that it cannot move. The O-ring O arranged in the recess 2c is between the recess 2c of the drainage device 2 and the mounting port 1a, and is strong enough to maintain watertightness. Depending on the design, the width of the gap between the drainage device 2 (or the recess 2c of the drainage device 2) and the mounting port 1a in the lateral direction and the dimensions of the O-ring O arranged between them are determined by the designer. Because it is possible to always secure and maintain the desired constant width and size, "the width between the drainage device 2 and the mounting port 1a and the O-ring that generate contact to the extent that rotation is possible while ensuring watertightness". By designing each member in the "dimension of O", the drainage device 2 can be rotated with respect to the mounting port 1a even after the drainage device 2 is attached to the mounting port 1a, and the drainage device 2 discharge port. It is possible to adjust 2d in a direction that is convenient for pipe connection.
Next, the fitting groove 8b of the deodorizing cylinder 8 is fitted into the protrusion 5b inside the drain plug 5 to make a connection. In this case, after inserting the deodorant cylinder 8 into the drainage port 4, the deodorant cylinder 8 is rotated in the tightening direction of the screw so that the fitting groove 8b and the protrusion 5b are fitted to each other and the drainage port 4 Fitted and fixed inside. Further, since the rotation work of the deodorant cylinder 8 is performed by gripping the handle portion 8a of the deodorant cylinder 8, it is possible to rotate the deodorant cylinder 8 more easily than by gripping and rotating a member having less unevenness such as a drain plug 5. It can be done, and it is easy to apply the force of the operator when rotating it. Therefore, as the rotation of the deodorant cylinder 8 is advanced, the drain plug 5 may rotate together with the deodorant cylinder 8 and the drain device 2 and the drain plug 5 may be further screwed. In this case, the connection between the drainage device 2 and the drainage plug 5 becomes stronger, and the connection between the drainage device 2 is more preferably performed.

上記のように構成した、第一実施例の排水器２に対し、低温ショーケースＳＣの底面Ｂ上に、低温ショーケースＳＣに収納した品物からのドリップや、低温ショーケースＳＣの冷却機器によって冷やされた空気からの結露水が発生すると、これらドリップ・結露水等の排水は、最終的に低温ショーケースＳＣの底面Ｂにある排水口４まで流下し、主には排水口４から、防臭筒８内部を通過し、オワン部２ｆ内部に溜まる。排水量が充分になると、オワン部２ｆに溜まった排水（封水）は、封水壁２ｅ上端を超えて排出口２ｄに流出し、排出口２ｄから下流側配管を経て下水側に排出される。
また、本実施例では、フランジ部５ａ下面と取付口１ａ周縁の上面との間には水密部材等の配置は無く、隙間を無くすような強い当接も行っていないため、排水の一部は、排水口４ではなく、フランジ部５ａの下面と取付口１ａの上面の間に流入する場合がある。この場合でも、フランジ部５ａの下面と取付口１ａの上面の間から、排水器２の係合爪３と取付口１ａの内側面の間、排水器２上縁、排水器２の内側面と防臭筒８外側面の間、を順に通過し、最終的には通水孔８ｃを介して、防臭筒８内に流入し、以上は排水口４からの排水と同様に流れて下流側の配管に向かって排出される。
また、オワン部２ｆ内に排水が溜まることで、防臭筒８内側面のオワン部２ｆ水面上から、防臭筒８外側面とオワン部２ｆ内側面の間のオワン部２ｆ水面上までの流路が、常に満水状態となる。この流路の満水状態部分を、下水側の臭気や害虫類は通過することができないため、下水側の臭気や害虫類は屋内側に侵入することができない。このようにして、本実施例の排水器２は、屋内側への臭気や害虫類の侵入を防ぐトラップ機能を備えてなる。即ち、本実施例は、防臭筒８とオワン部２ｆと、からなるトラップ部を備えた排水トラップである。 The drainage device 2 of the first embodiment configured as described above is cooled by a drip from an item stored in the low temperature showcase SC or a cooling device of the low temperature showcase SC on the bottom surface B of the low temperature showcase SC. When dew condensation water is generated from the generated air, the drainage of these drip and dew condensation water finally flows down to the drainage port 4 on the bottom surface B of the low temperature showcase SC, and mainly from the drainage port 4 to the deodorant cylinder. It passes through the inside of 8 and collects inside the Owan part 2f. When the amount of drainage becomes sufficient, the drainage (sealing water) accumulated in the Owan portion 2f flows out to the discharge port 2d beyond the upper end of the water sealing wall 2e, and is discharged from the discharge port 2d to the sewage side via the downstream pipe.
Further, in this embodiment, no watertight member or the like is arranged between the lower surface of the flange portion 5a and the upper surface of the peripheral surface of the mounting port 1a, and strong contact is not performed to eliminate the gap, so that a part of the drainage is partially drained. , It may flow between the lower surface of the flange portion 5a and the upper surface of the mounting port 1a instead of the drain port 4. Even in this case, from between the lower surface of the flange portion 5a and the upper surface of the mounting port 1a, between the engaging claw 3 of the drainer 2 and the inner side surface of the mounting port 1a, the upper edge of the drainer 2 and the inner surface of the drainer 2. It passes through between the outer surfaces of the deodorant cylinder 8 in order, and finally flows into the deodorant cylinder 8 through the water passage hole 8c, and the above flows in the same manner as the drainage from the drain port 4, and the pipe on the downstream side. It is discharged toward.
Further, by collecting drainage in the Owan portion 2f, a flow path from the Owan portion 2f water surface on the inner surface of the deodorizing cylinder 8 to the Owan portion 2f water surface between the outer surface of the deodorizing cylinder 8 and the inner surface of the Owan portion 2f , It is always full. Since the odor and pests on the sewage side cannot pass through the filled portion of this flow path, the odor and pests on the sewage side cannot invade the indoor side. In this way, the drainage device 2 of the present embodiment has a trap function for preventing the invasion of odors and pests into the indoor side. That is, this embodiment is a drain trap including a trap portion including a deodorant cylinder 8 and an Owan portion 2f.

上記のように構成されたトラップ機能付き排水器２は、施工時には、従来例の排水器２と異なり、取付口１ａの上方側と下方側の両方に同時に作業を行う必要は無く、上方側からの作業のみ、下方側からの作業のみ、のいずれかの作業のみで排水器２の取り付けを行うことができ、上方側及び下方側の両側から、同時に作業を行う必要があった従来の排水器２と比べて、取り付け作業が極めて容易になっている。
また、上記実施例にて記載したように、排水器２と取付口１ａとの水密的な接続を、上下方向に押圧することなく、側面方向へのＯリングＯを利用した接続により行うように構成してなる。これにより、排水器２の取り付け後であっても、排水器２を取付口１ａに対して回転させて、方向の調整を行うことが可能となっている。
このように、フランジ部５ａと取付口１ａ周縁とは強く押し圧されていないため、フランジ部５ａ下面と取付口１ａ周縁上面との間には隙間が発生し、排水の一部が該隙間に流入する可能性があるが、このような隙間に入り込んだ排水も、排水器２と取付口１ａの間に配置されたＯリングＯによって止水され、低温ショーケースＳＣの底面Ｂの下面に漏水することなく、通水孔８ｃを介して防臭筒８の内部に排出され、排水口４からの排水と共に、下流側に支障なく排出される。 Unlike the conventional drainage device 2, the drainage device 2 with a trap function configured as described above does not need to work on both the upper side and the lower side of the mounting port 1a at the same time, and from the upper side. The drainage device 2 can be attached only by the work of the above side or the work from the lower side only, and it is necessary to perform the work from both the upper side and the lower side at the same time. Compared with 2, the installation work is extremely easy.
Further, as described in the above embodiment, the watertight connection between the drainage device 2 and the mounting port 1a is performed by connecting using the O-ring O in the side direction without pressing in the vertical direction. It consists of. As a result, even after the drainage device 2 is attached, the drainage device 2 can be rotated with respect to the attachment port 1a to adjust the direction.
As described above, since the flange portion 5a and the peripheral edge of the mounting port 1a are not strongly pressed, a gap is generated between the lower surface of the flange portion 5a and the upper surface of the peripheral edge of the mounting port 1a, and a part of the drainage is in the gap. Although there is a possibility of inflow, the drainage that has entered such a gap is also stopped by the O-ring O arranged between the drainer 2 and the attachment port 1a, and leaks to the lower surface of the bottom surface B of the low temperature showcase SC. It is discharged into the deodorant cylinder 8 through the water passage hole 8c without any trouble, and is discharged to the downstream side together with the drainage from the drain port 4.

次に、本発明の第二実施例について、図面を参照しつつ説明する。
図４及び図５に示した本発明の第二実施例の排水器２は、商品棚Ｔ上を低温に維持しつつ商品の陳列を行う、低温ショーケースＳＣの結露水の排水を行う、トラップ機能付きの排水器２であって、以下に記載する排水器２、排水栓５、防臭筒８、より構成されてなり、以下に記載する低温ショーケースＳＣの取付口１ａに施工される。
図１に示した、低温ショーケースＳＣは、生鮮食品など低温を維持しつつ商品の展示を行うショーケースであって、前面及び側面の一部が開放された略箱体形状を成すと共に、該箱体の内部に、上下方向に複数の商品棚Ｔを有してなる。また、商品棚Ｔの更に下方であって、箱体の底面Ｂに、上下に貫通する取付口１ａを備えてなる。
低温ショーケースＳＣの底面Ｂについて詳述すると、低温ショーケースＳＣの底面Ｂは、以下に記載する金属板Ｍ、及び取付口部材１から構成される。
金属板Ｍは、底面Ｂの上面、及び下面のそれぞれに各１枚づつ、計２枚使用される金属製の平板であって、２枚共に平面視円形の貫通孔Ｈを備えてなる。
取付口部材１は、断面視外側方向に向かって開口する断面視略コの字形状を成す筒体であって、筒体の内部が取付口１ａを形成する。また、取付口１ａの上下方向の中間部分に、中心方向に向けて開口した溝部１ｃを備えてなる。尚、後に詳述するが、取付口１ａの一部は、施工完了時排水口４を形成する。
上記金属板Ｍ及び取付口部材１を低温ショーケースＳＣの底面Ｂとする場合、二枚の金属板Ｍの間に取付口部材１を配置する。この時、取付口部材１の取り付け口と、上下の金属板Ｍの貫通孔Ｈとが同心円状になるように配置した上で、両面テープを用いて取付口部材１と金属板Ｍを仮止めする。
その後、上下の金属板Ｍの間に、発泡ウレタンＦなどの樹脂を充満させることで、上下の金属板Ｍ、及び取付口部材１が分離不可能な状態となって、取付口１ａを備えた低温ショーケースＳＣの底面Ｂという、一体の部材として使用することができる。
排水器２は、有底略円筒形状を成す、硬質樹脂からなる部材であって、上端部分には複数の係合爪３を、内側面部分には受入部２ａを、外側面部分には上方から順に、凹部２ｃ、及び排出口２ｄをそれぞれ備えてなる。以下に各構成について説明する。
係合爪３は排水器２本体の筒部分の上端から上方に延出されたリブ部３ａと、該リブ部３ａの上端において外側方向に突出した爪部３ｂを備えてなる。該係合爪３は、リブ部３ａが撓むことで該爪部３ｂは内側に縮径し、溝部１ｃの開口部分の径よりも小径となって爪部３ｂが通過可能となると共に、リブ部３ａが撓まない状態では、爪部３ｂ先端は溝部１ｃの開口部分の径よりも大径を成すため、係合爪３の爪部３ｂが溝部１ｃに嵌入し、係合爪３が溝部１ｃに係合する。
受入部２ａは、排水器２の、係合爪３よりも下方の内周部分であって、排水栓５を受け入れるように排水栓５よりも大径に形成され、周縁に沿って複数の爪形状部分からなる嵌合部６ａを設けてなる。
また、同じく内周部分に、嵌合部６ａとは別に、縦方向に設けられた溝からなるガイド溝９ａを備えてなる。
凹部２ｃは、排水器２の外側面に、周縁に沿って全周に渡って設けられた溝であって、施工時にはこの凹部２ｃ内に水密部材としてのＯリングＯが配置される。
排出口２ｄは排水器２の内部に連通するように設けられた、下流側の配管が接続される筒部分であって、排水器２の底面部分を含む側面部分に、側面方向を向いて設けられてなる。
また、排出口２ｄの内部であって、排出口２ｄと排水器２の側面とのほぼ境界部分に、施工完了時トラップ機能を形成するための封水壁２ｅを、底壁から排出口２ｄの中心程度の高さ位置まで延出して設けてなる。この封水壁２ｅによって、排水器２の内部には、排水口４から流入した排水が貯水されるオワン部２ｆが形成される。
排水栓５は略円筒形状を成す、硬質樹脂からなる部材であって、その内部には排水口４の一部が形成されると共に、その外側面には、排水器２の受入部２ａの嵌合部６ａの爪形状部分と解除不可能、いわゆる嵌め殺しにて嵌合する、爪形状部分からなる被嵌合部６ｂを設けてなる。
また筒部分の上端には、周縁に沿って全周に渡って４５度前後の角度で外方向に突出するフランジ部５ａを備えてなる。このフランジ部５ａは、断面外周側程先細りとなる形状であり、応力が作用してない状態では、その外径は取付口１ａの内径よりも若干だけ大径である。
施工完了時、フランジ部５ａの先端（外縁部分）は、樹脂弾性によって若干内径側に撓むことで、取付口１ａの内側面にほぼ隙間なく当接する。このように構成したことで、排水口４は、排水栓５のフランジ部５ａよりも上方は取付口１ａによって、下方は排水栓５によって、それぞれ形成される。
また、外周面に、嵌合部６ａとは別に、排水栓５のガイド溝９ａに収納される、上下方向を向いたリブ片であるガイドリブ９ｂを備えてなる（図５においては、図面に対し排水栓５の背面側にあるため、点線にて示す）。ガイド溝９ａにガイドリブ９ｂが嵌めこまれることにより、施工完了時、排水器２に対して排水栓５の回動が不可能となる。
また、排水栓５の円筒部分の内部に、側面視同じ高さ位置であって、平面視中心軸から見て９０度毎に四か所、突起部５ｂを備えてなる。
防臭筒８は、略円筒形状を成す部材であって、その上端部分には取っ手部８ａが備えられてなると共に、その外側面には、上方から順に、嵌合溝８ｂ、通水孔８ｃ、環状パッキング８ｄ、がそれぞれ設けられてなり、施工完了時には、上端部分は排水口４内に配置され、下端部分は、排水器２のオワン部２ｆ内に配置される。以下に各構成について説明する。
取っ手部８ａは防臭筒８の上端から防臭筒８内部の一部までにわたって備えられた、防臭筒８の保持を容易にするためのリブ片である。
嵌合溝８ｂは、排水栓５の突起部５ｂと嵌合する溝部分であって、排水口４内に防臭筒８を挿入した後、防臭筒８を回転させることで、嵌合溝８ｂと突起部５ｂが嵌合して、排水口４内に嵌合固定される。また嵌合時とは逆方向に回転させることで、嵌合を解除して排水口４から着脱することも可能である。
通水孔８ｃは、防臭筒８の内外を貫通する開口であり、排水器２内側面と防臭筒８外側面との間であって、環状パッキング８ｄよりも上方の部分に溜まった排水が、この通水孔８ｃを介して防臭筒８内部に排出される。
環状パッキング８ｄは、防臭筒８の外側面に、周縁に沿って全周に渡って配置される、断面略Ｖ字形状を成す水密部材であって、インサート成形にて防臭筒８と一体に成形されてなり、施工時にはこの環状パッキング８ｄが排水栓５内部と水密的に接続するように構成されてなる。 Next, a second embodiment of the present invention will be described with reference to the drawings.
The drainage device 2 of the second embodiment of the present invention shown in FIGS. 4 and 5 displays products while maintaining a low temperature on the product shelf T, drains the dew condensation water of the low temperature showcase SC, and is a trap. The drainage device 2 with a function is composed of the drainage device 2, the drain plug 5, and the deodorant cylinder 8 described below, and is installed at the attachment port 1a of the low temperature showcase SC described below.
The low-temperature showcase SC shown in FIG. 1 is a showcase for displaying products such as fresh food while maintaining a low temperature, and has a substantially box-shaped shape with a part of the front surface and side surfaces open. A plurality of product shelves T are provided in the vertical direction inside the box. Further, a mounting port 1a penetrating vertically is provided on the bottom surface B of the box body, which is further below the product shelf T.
The bottom surface B of the low temperature showcase SC will be described in detail. The bottom surface B of the low temperature showcase SC is composed of the metal plate M described below and the attachment port member 1.
The metal plate M is a metal flat plate used in a total of two plates, one on each of the upper surface and the lower surface of the bottom surface B, both of which are provided with through holes H having a circular shape in a plan view.
The mounting port member 1 is a tubular body having a substantially U-shaped cross-sectional view that opens toward the outside in cross-sectional view, and the inside of the tubular body forms the mounting port 1a. Further, a groove portion 1c opened toward the center is provided at an intermediate portion in the vertical direction of the mounting port 1a. As will be described in detail later, a part of the mounting port 1a forms a drainage port 4 when the construction is completed.
When the metal plate M and the mounting port member 1 are the bottom surface B of the low temperature showcase SC, the mounting port member 1 is arranged between the two metal plates M. At this time, after arranging the mounting port of the mounting port member 1 and the through holes H of the upper and lower metal plates M so as to be concentric, the mounting port member 1 and the metal plate M are temporarily fixed using double-sided tape. To do.
After that, by filling the upper and lower metal plates M with a resin such as urethane foam F, the upper and lower metal plates M and the attachment port member 1 become inseparable, and the attachment port 1a is provided. It can be used as an integral member called the bottom surface B of the low temperature showcase SC.
The drainage device 2 is a member made of hard resin having a substantially cylindrical shape with a bottom, and has a plurality of engaging claws 3 on the upper end portion, a receiving portion 2a on the inner side surface portion, and an upper portion on the outer surface portion. A recess 2c and a discharge port 2d are provided in this order. Each configuration will be described below.
The engaging claw 3 includes a rib portion 3a extending upward from the upper end of the tubular portion of the main body of the drainage device 2, and a claw portion 3b protruding outward at the upper end of the rib portion 3a. As the rib portion 3a bends, the diameter of the engaging claw 3b is reduced inward, the diameter becomes smaller than the diameter of the opening portion of the groove portion 1c, and the claw portion 3b can pass through the engaging claw 3.

上記のように構成された本実施例の排水器２を施工する場合、以下のような手順にて施工を行う。
まず、低温ショーケースＳＣの底面Ｂであって、取付口１ａの下方から、排水器２を、係合爪３を上側（取付口１ａ側）に向けて挿入する。排水器２を取付口１ａに挿入すると、係合爪３の爪部３ｂが、取付口１ａの内周面に当接し、一旦リブ部３ａが樹脂弾性により内周側（内側）に撓むことで縮径する。そのまま上昇させると、爪部３ｂが溝部１ｃに到達し、溝部１ｃに爪部３ｂが嵌り込むことで、溝部１ｃが係合爪３と係合する。
この爪部３ｂが溝部１ｃに嵌り込んだ状態では、排水器２は、係合爪３のリブ部３ａが内周側に撓まない限り、取付口１ａに対し、回動は可能であるが、抜脱することも、また上下動することもない状態となる。この状態は、排水器２が取付口１ａに取り付けられてなるが、係合爪３の係合の解除が容易で、排水器２としての実際の使用に耐えられるほど確実な取り付けが行われていないため、「仮止め状態」と呼ばれる。
この仮止め状態より、低温ショーケースＳＣの底面Ｂに対し上方から、排水器２の上方の受入部２ａに、排水栓５を挿入する。この際は、排水栓５のガイドリブ９ｂが受入部２ａのガイド溝９ａに合致して嵌り込むように位置を調整し、上方からそのまま回転させること無く排水栓５を受入部２ａに挿入することで、排水器２の嵌合部６ａに、排水栓５の被嵌合部６ｂが抜脱不可能な状態にて嵌合することで、排水器２に排水栓５が抜脱不可能に接続される。この時、排水栓５のフランジ部５ａの先端部分は、取付口１ａ内に入り込み、樹脂弾性によって若干内径側に撓み、取付口１ａの内側面にほぼ隙間なく当接している。
また、排水栓５のガイドリブ９ｂが排水器２のガイド溝９ａに収納された状態となり、排水器２に対して排水栓５の回動が不可能となる。あくまで排水器２に対する排水栓５の回動が不可能なだけであり、取付口１ａに対する排水器２の回動は可能である。
この排水栓５が排水器２の受入部２ａに接続された状態では、係合爪３のリブ片に排水栓５の外側面が当接した状態、又は若干の隙間を有するものの、爪部３ｂが溝部１ｃから抜脱するほどに内周側に撓む前に、排水栓５の外側面に当接してそれ以上内周側に撓むことが不可能な状態となっており、排水器２が取付口１ａから抜脱することは不可能となっている。また、溝部１ｃの上方の壁面に爪部３ｂの上面が、下方の壁面に爪部３ｂの下面が、それぞれ若干の遊び空間のみを残して当接するため、単に排水器２が取付口１ａから抜脱不可能となるだけではなく、排水器２が取付口１ａから極端に上下動することも無い。
次に、排水器２の排出口２ｄに下流側の排水配管を接続する。この際には、接着剤などを利用し、又はネジとパッキングによる水密的な接続を利用し、漏水が生じないように確実に接続を行う。また、この接続の際に、排水器２の排出口２ｄが、床下配管の接続に適切な方向を向いていない場合には、排水器２を取付口１ａに対して回転させ、方向の調整を行う。本発明では、排水器２が取付口１ａから抜脱しない理由は、従来例のように、取付口１ａ周縁を上下に締め付けることで面同士が強く当接し、回動も不可能なように固定されているためではなく、係合爪３が内周側に撓むことが不可能となったため、排水器２の取付口１ａからの抜脱が不可能となったためであり、面同士が、回動が不可能なほど強く当接している箇所は無い。
詳述すると、排水栓５のフランジ部５ａ先端と取付口１ａの当接は、当接箇所がフランジ部５ａの先端であって面積としては狭く、また水密を確保していないため、取付口１ａに対する排水器２の回動を妨げることは無い。
また、凹部２ｃに配置されているＯリングＯは、排水器２の凹部２ｃと取付口１ａの間であって、水密を維持できる程度には強い、面による当接を、排水器２また取付口１ａの間に生じているが、排水器２（又は排水器２の凹部２ｃ）と取付口１ａの側面方向の隙間の幅と、その間に配置されるＯリングＯの寸法は、設計により、設計者が希望する一定の幅や大きさを常に確保・維持できるため、「水密を確保しつつ、回転も可能な程度の当接を生じる、排水器２と取付口１ａの間の幅、及びＯリングＯの寸法」に各部材を設計することで、排水器２の取付口１ａへの取り付け後であっても、排水器２を取付口１ａに対して回動可能とし、排水器２の排出口２ｄを配管接続に都合の良い方向に向けて調整することが可能である。
次に、排水栓５内部の突起部５ｂに、防臭筒８の嵌合溝８ｂを嵌合させて接続を行う。この際には、排水口４内に防臭筒８を挿入した後、防臭筒８を回転させることで、嵌合溝８ｂと突起部５ｂが嵌合して、排水口４内に嵌合固定される。この時には、ガイドリブ９ｂがガイド溝９ａに嵌り込むことで、排水器２に対して排水栓５が回転することが不可能となっており、排水栓５が防臭筒８と一体になって回転し、最後まで回転の嵌合を進めることができなくなる、という、いわゆる供回りの発生を防止している。尚、この防臭筒８を取り付ける時点では、排水器２の排出口２ｄは床下配管に接続されており、床下配管によって方向を固定され、排水器２も排水栓５や防臭筒８と共に回転してしまう、ということは無い。 When constructing the drainage device 2 of the present embodiment configured as described above, the procedure is as follows.
First, the drainage device 2 is inserted from below the mounting port 1a on the bottom surface B of the low temperature showcase SC with the engaging claw 3 facing upward (mounting port 1a side). When the drainer 2 is inserted into the mounting port 1a, the claw portion 3b of the engaging claw 3 comes into contact with the inner peripheral surface of the mounting port 1a, and the rib portion 3a once bends to the inner peripheral side (inside) due to resin elasticity. Reduce the diameter with. When the claw portion 3b is raised as it is, the claw portion 3b reaches the groove portion 1c, and the claw portion 3b fits into the groove portion 1c, so that the groove portion 1c engages with the engaging claw portion 3.
In the state where the claw portion 3b is fitted into the groove portion 1c, the drainer 2 can rotate with respect to the mounting port 1a as long as the rib portion 3a of the engaging claw 3 does not bend to the inner peripheral side. , It will not be pulled out or moved up and down. In this state, the drainage device 2 is attached to the attachment port 1a, but the engagement of the engaging claw 3 is easily disengaged, and the drainage device 2 is securely attached so as to withstand the actual use as the drainage device 2. Because there is no such thing, it is called "temporary fixing state".
From this temporarily fixed state, the drain plug 5 is inserted into the receiving portion 2a above the drain device 2 from above with respect to the bottom surface B of the low temperature showcase SC. At this time, the position of the guide rib 9b of the drain plug 5 is adjusted so that it fits into the guide groove 9a of the receiving portion 2a, and the drain plug 5 is inserted into the receiving portion 2a without being rotated as it is from above. By fitting the fitted portion 6b of the drain plug 5 into the fitting portion 6a of the drainage device 2 in a non-detachable state, the drain plug 5 is connected to the drainage device 2 in a non-detachable state. To. At this time, the tip portion of the flange portion 5a of the drain plug 5 enters the mounting port 1a, is slightly bent toward the inner diameter side due to the elasticity of the resin, and is in contact with the inner side surface of the mounting port 1a with almost no gap.
Further, the guide rib 9b of the drain plug 5 is housed in the guide groove 9a of the drain device 2, and the drain plug 5 cannot rotate with respect to the drain plug 2. It is only impossible to rotate the drain plug 5 with respect to the drain device 2, and the drain device 2 can be rotated with respect to the attachment port 1a.
When the drain plug 5 is connected to the receiving portion 2a of the drainer 2, the outer surface of the drain plug 5 is in contact with the rib piece of the engaging claw 3, or the claw portion 3b has a slight gap. Before it bends to the inner peripheral side enough to be pulled out from the groove 1c, it comes into contact with the outer surface of the drain plug 5 and cannot bend further to the inner peripheral side. Is impossible to remove from the mounting port 1a. Further, since the upper surface of the claw portion 3b is in contact with the upper wall surface of the groove portion 1c and the lower surface of the claw portion 3b is in contact with the lower wall surface leaving only a small play space, the drainer 2 is simply pulled out from the attachment port 1a. Not only is it impossible to remove it, but the drainage device 2 does not move up and down extremely from the attachment port 1a.
Next, the drainage pipe on the downstream side is connected to the discharge port 2d of the drainage device 2. In this case, use an adhesive or a watertight connection with screws and packing to ensure the connection so that water leakage does not occur. Further, at the time of this connection, if the drain port 2d of the drain device 2 does not face an appropriate direction for connecting the underfloor piping, the drain device 2 is rotated with respect to the mounting port 1a to adjust the direction. Do. In the present invention, the reason why the drainage device 2 does not come off from the mounting port 1a is that the surfaces are strongly in contact with each other by tightening the peripheral edge of the mounting port 1a up and down as in the conventional example, and the drainage device 2 is fixed so that it cannot rotate. This is not because the engaging claws 3 are bent toward the inner circumference side, but because it is impossible to remove the drainage device 2 from the attachment port 1a. There is no place where it is in contact so strongly that it cannot move.
More specifically, the contact between the tip of the flange portion 5a of the drain plug 5 and the mounting port 1a is such that the contact point is the tip of the flange portion 5a, the area is narrow, and watertightness is not ensured. It does not hinder the rotation of the drainage device 2 with respect to.
Further, the O-ring O arranged in the recess 2c is between the recess 2c of the drainage device 2 and the attachment port 1a, and is strong enough to maintain watertightness. Although it occurs between the ports 1a, the width of the gap between the drainage device 2 (or the recess 2c of the drainage device 2) and the mounting port 1a in the side surface direction and the dimensions of the O-ring O arranged between them are determined by design. Since the constant width and size desired by the designer can always be secured and maintained, "the width between the drainage device 2 and the mounting port 1a, which causes contact to the extent that rotation is possible while ensuring watertightness, and By designing each member in the "dimensions of O-ring O", the drainage device 2 can be rotated with respect to the mounting port 1a even after the drainage device 2 is attached to the mounting port 1a. It is possible to adjust the discharge port 2d in a direction convenient for pipe connection.
Next, the fitting groove 8b of the deodorizing cylinder 8 is fitted into the protrusion 5b inside the drain plug 5 to make a connection. In this case, after inserting the deodorizing cylinder 8 into the drainage port 4, the deodorizing cylinder 8 is rotated so that the fitting groove 8b and the protrusion 5b are fitted and fitted and fixed in the drainage port 4. To. At this time, since the guide rib 9b is fitted into the guide groove 9a, it is impossible for the drain plug 5 to rotate with respect to the drain device 2, and the drain plug 5 rotates integrally with the deodorizing cylinder 8. It prevents the occurrence of so-called rotation, which means that the fitting of rotation cannot be advanced to the end. At the time of attaching the deodorant cylinder 8, the discharge port 2d of the drainer 2 is connected to the underfloor pipe, the direction is fixed by the underfloor pipe, and the drainer 2 also rotates together with the drain plug 5 and the deodorant cylinder 8. There is no such thing as ending up.

上記のように構成した、第二実施例の排水器２に対し、低温ショーケースＳＣの底面Ｂ上に、低温ショーケースＳＣに収納した品物からのドリップや、低温ショーケースＳＣの冷却機器によって冷やされた空気からの結露水が発生すると、これらドリップ・結露水等の排水は、最終的に低温ショーケースＳＣの底面Ｂにある排水口４まで流下し、主には排水口４から、防臭筒８内部を通過し、オワン部２ｆ内部に溜まる。排水量が充分になると、オワン部２ｆに溜まった排水（封水）は、封水壁２ｅ上端を超えて排出口２ｄに流出し、排出口２ｄから下流側配管を経て下水側に排出される。
また、本実施例では、フランジ部５ａ下面と取付口１ａ周縁の上面との間には水密部材等の配置は無く、隙間を無くすような強い当接も行っていないため、排水の一部は、排水口４ではなく、フランジ部５ａの下面と取付口１ａの上面の間に流入する場合がある。この場合でも、フランジ部５ａの下面と取付口１ａの上面の間から、排水器２の係合爪３と取付口１ａの内側面の間、排水器２上縁、排水器２の内側面と防臭筒８外側面の間、を通過し、最終的には通水孔８ｃを介して、防臭筒８内に流入し、以上は排水口４からの排水と同様に流れて下流側の配管に向かって排出される。
また、オワン部２ｆ内に排水が溜まることで、防臭筒８内側面のオワン部２ｆ水面上から、防臭筒８外側面とオワン部２ｆ内側面の間のオワン部２ｆ水面上までの流路が、常に満水状態となる。この流路の満水状態部分を、下水側の臭気や害虫類は通過することができないため、下水側の臭気や害虫類は屋内側に侵入することができない。このようにして、本実施例の排水器２は、屋内側への臭気や害虫類の侵入を防ぐトラップ機能を備えてなる。即ち、本実施例は、防臭筒８とオワン部２ｆと、からなるトラップ部を備えた排水トラップである。 The drainage device 2 of the second embodiment configured as described above is cooled by a drip from an item stored in the low temperature showcase SC or a cooling device of the low temperature showcase SC on the bottom surface B of the low temperature showcase SC. When dew condensation water is generated from the generated air, the drainage of these drip and dew condensation water finally flows down to the drainage port 4 on the bottom surface B of the low temperature showcase SC, and mainly from the drainage port 4 to the deodorant cylinder. It passes through the inside of 8 and collects inside the Owan part 2f. When the amount of drainage becomes sufficient, the drainage (sealing water) accumulated in the Owan portion 2f flows out to the discharge port 2d beyond the upper end of the water sealing wall 2e, and is discharged from the discharge port 2d to the sewage side via the downstream pipe.
Further, in this embodiment, no watertight member or the like is arranged between the lower surface of the flange portion 5a and the upper surface of the peripheral surface of the mounting port 1a, and strong contact is not performed to eliminate the gap, so that a part of the drainage is partially drained. , It may flow between the lower surface of the flange portion 5a and the upper surface of the mounting port 1a instead of the drain port 4. Even in this case, from between the lower surface of the flange portion 5a and the upper surface of the mounting port 1a, between the engaging claw 3 of the drainer 2 and the inner side surface of the mounting port 1a, the upper edge of the drainer 2 and the inner surface of the drainer 2. It passes between the outer surfaces of the deodorant cylinder 8 and finally flows into the deodorant cylinder 8 through the water passage hole 8c, and the above flows in the same manner as the drainage from the drain port 4 to the downstream pipe. It is discharged toward.
Further, by collecting drainage in the Owan portion 2f, a flow path from the Owan portion 2f water surface on the inner surface of the deodorizing cylinder 8 to the Owan portion 2f water surface between the outer surface of the deodorizing cylinder 8 and the inner surface of the Owan portion 2f , It is always full. Since the odor and pests on the sewage side cannot pass through the filled portion of this flow path, the odor and pests on the sewage side cannot invade the indoor side. In this way, the drainage device 2 of the present embodiment has a trap function for preventing the invasion of odors and pests into the indoor side. That is, this embodiment is a drain trap including a trap portion including a deodorant cylinder 8 and an Owan portion 2f.

上記のように構成されたトラップ機能付き排水器２は、施工時には、従来例の排水器２と異なり、取付口１ａの上方側と下方側の両方に同時に作業を行う必要は無く、上方側からの作業のみ、下方側からの作業のみ、のいずれかの作業のみで排水器２の取り付けを行うことができ、上方側及び下方側の両側から、同時に作業を行う必要があった従来の排水器２と比べて、取り付け作業が極めて容易になっている。
また、上記実施例にて記載したように、排水器２と取付口１ａとの水密的な接続を、上下方向に押圧することなく、側面方向へのＯリングＯを利用した接続により行うように構成してなる。
また、排水栓５のフランジ部５ａ先端と取付口１ａの当接も、当接箇所の面積が狭く、また水密を確保していないため、取付口１ａに対する排水器２の回動を妨げることは無い。
これにより、排水器２の取り付け後であっても、排水器２を取付口１ａに対して回転させて、方向の調整を行うことが可能となっている。
このように、フランジ部５ａと取付口１ａとは強く押し圧されていないため、フランジ部５ａ先端と取付口１ａとの間に排水が入り込み、滲むようにして、排水の一部が排水栓５と取付口１ａの隙間に流入する可能性があるが、このような隙間に入り込んだ排水も、排水器２と取付口１ａの間に配置されたＯリングＯによって止水され、低温ショーケースＳＣの底面Ｂの下面に漏水することなく、通水孔８ｃを介して防臭筒８の内部に排出され、排水口４からの排水と共に、下流側に支障なく排出される。 Unlike the conventional drainage device 2, the drainage device 2 with a trap function configured as described above does not need to work on both the upper side and the lower side of the mounting port 1a at the same time, and from the upper side. The drainage device 2 can be attached only by the work of the above side or the work from the lower side only, and it is necessary to perform the work from both the upper side and the lower side at the same time. Compared with 2, the installation work is extremely easy.
Further, as described in the above embodiment, the watertight connection between the drainage device 2 and the mounting port 1a is performed by connecting using the O-ring O in the side direction without pressing in the vertical direction. It consists of.
Further, the contact between the tip of the flange portion 5a of the drain plug 5 and the attachment port 1a also has a small contact area and does not ensure watertightness, so that the rotation of the drainer 2 with respect to the attachment port 1a may be hindered. There is no.
As a result, even after the drainage device 2 is attached, the drainage device 2 can be rotated with respect to the attachment port 1a to adjust the direction.
In this way, since the flange portion 5a and the mounting port 1a are not strongly pressed against each other, drainage enters between the tip of the flange portion 5a and the mounting port 1a so as to bleed, and a part of the drainage is mounted with the drain plug 5. There is a possibility that the water may flow into the gap of the port 1a, but the drainage that has entered such a gap is also stopped by the O-ring O arranged between the drainer 2 and the mounting port 1a, and the bottom surface of the low temperature showcase SC. Without leaking to the lower surface of B, the water is discharged to the inside of the deodorizing cylinder 8 through the water passage hole 8c, and is discharged to the downstream side without any trouble together with the drainage from the drain port 4.

本発明の実施例は以上のようであるが、本発明は上記実施例に限定される物ではなく、主旨を変更しない範囲において自由に変更が可能である。
例えば、上記実施例では、排水器２を取り付ける排水機器を、低温ショーケースＳＣとしているが、本発明は上記実施例に限定されるものでは無く、洗面台、流し台、浴槽や浴室の排水口４に用いる排水器２等、どのような排水機器に採用しても構わない。又、本発明は必ずしも排水口に取り付けられる必要はなく、洗面台のオーバーフロー流路等に取り付けられても良い。 Examples of the present invention are as described above, but the present invention is not limited to the above examples, and can be freely changed without changing the gist.
For example, in the above embodiment, the drainage device to which the drainage device 2 is attached is a low temperature showcase SC, but the present invention is not limited to the above embodiment, and the washbasin, sink, bathtub, and bathroom drainage port 4 It may be used in any drainage device such as the drainage device 2 used in the above. Further, the present invention does not necessarily have to be attached to the drain port, and may be attached to the overflow flow path of the wash basin or the like.

また、上記各実施例では、排水器２を取付口１ａに取り付けた後、排水器２の方向を調整した上で、排出口２ｄに床下配管を接続しているが、本発明は上記実施例に限定されるものでは無く、手順を変更し、先に排出口２ｄに床下配管を接続した後、排水器２を取付口１ａに取り付けるようにして施工を行っても構わない。 Further, in each of the above embodiments, after the drainage device 2 is attached to the attachment port 1a, the direction of the drainage device 2 is adjusted, and then the underfloor piping is connected to the drainage port 2d. However, the procedure may be changed so that the drainage device 2 is attached to the attachment port 1a after the underfloor piping is first connected to the discharge port 2d.

また、上記各実施例では、排水器２は取付口１ａに対して３６０度自在に回動可能であったが、角度規制手段等を設けることにより、所定角度の範囲内でのみ自在に回動可能であっても良い。又、施工が全て完了した際には回動不可能となるように排水器２を固定するなど、角度固定機構を備えても良いものである。この場合においては、排水器２の方向が決まった後に、予期せぬ方向に排水器２が回動してしまうことを防ぐ事により、施工性を向上させることができる。
図６及び図７に示した実施例は、上記角度規制手段、及び施工完了後には回動不可能となる角度固定機構を備えた排水配管である。具体的には、第一実施例の排水装置に、角度規制手段、及び角度固定機構として、爪部３ｂの一部にのみ三角形の縦条部分１０を、取付部１ａの一部にのみ上記爪部３ｂの縦条部分１０に対応する縦溝部分１１を、それぞれ設けてなる。図７より明らかなように、図６のＡ−Ａ断面図において、取付部１ａの縦溝部分１１を有する範囲は中心に対して約９０度、一方爪部３ｂの縦条部分１０を有する範囲は中心に対して約２０度であり、且つ縦条部分１０の外径は、縦溝部分１１を設けない取付部１ａの内径よりも大径である。
このため、爪部３ｂの縦条部分１０は、取付部１ａの縦溝部分１１の範囲内にしか配置できず、排水器２を取付口部材１に取り付けても、７０度の範囲内でしか回動できない。即ち、角度規制手段を有してなる。
また、排水器２を取付口部材１に嵌合させただけの状態では、縦条部分１０と縦溝部分１１が歯合しているものの、係合爪３のリブ部３ａの弾性を利用して、係合爪３を撓ませ、縦条部分１０と縦溝部分１１の歯合を解除して排水器２を取付口部材１に対し回動させることができる。しかし、排水栓５を排水器２に取り付けると、係合爪３が撓むことは不可能となり、縦条部分１０と縦溝部分１１の歯合の解除も不可能となって、排水器２を取付口部材１に対し回動させることが不可能になる。即ち、角度固定機構を有してなる。
このように、図６また図７に示した実施例の排水配管は、取付口部材１に対して排水器２の角度方向の範囲を規制する角度規制手段、及び施工完了後には回動不可能となる角度固定機構を備えた排水配管である。 Further, in each of the above embodiments, the drainage device 2 can freely rotate 360 degrees with respect to the attachment port 1a, but by providing an angle regulating means or the like, the drainage device 2 can rotate freely only within a predetermined angle range. It may be possible. Further, an angle fixing mechanism may be provided, such as fixing the drainage device 2 so that it cannot rotate when all the construction is completed. In this case, workability can be improved by preventing the drainer 2 from rotating in an unexpected direction after the direction of the drainer 2 is determined.
The embodiment shown in FIGS. 6 and 7 is a drainage pipe provided with the angle regulating means and an angle fixing mechanism that cannot rotate after the construction is completed. Specifically, in the drainage device of the first embodiment, as an angle regulating means and an angle fixing mechanism, a triangular vertical strip portion 10 is provided only on a part of the claw portion 3b, and the above claw is provided only on a part of the mounting portion 1a. A vertical groove portion 11 corresponding to the vertical strip portion 10 of the portion 3b is provided. As is clear from FIG. 7, in the cross-sectional view taken along the line AA of FIG. 6, the range having the vertical groove portion 11 of the mounting portion 1a is about 90 degrees with respect to the center, while the range having the vertical strip portion 10 of the claw portion 3b. Is about 20 degrees with respect to the center, and the outer diameter of the vertical strip portion 10 is larger than the inner diameter of the mounting portion 1a in which the vertical groove portion 11 is not provided.
Therefore, the vertical strip portion 10 of the claw portion 3b can be arranged only within the range of the vertical groove portion 11 of the mounting portion 1a, and even if the drainage device 2 is attached to the mounting port member 1, it is only within the range of 70 degrees. Cannot rotate. That is, it has an angle regulating means.
Further, in the state where the drainer 2 is simply fitted to the attachment port member 1, the vertical strip portion 10 and the vertical groove portion 11 are in mesh with each other, but the elasticity of the rib portion 3a of the engaging claw 3 is utilized. Then, the engaging claw 3 can be bent, the teeth of the vertical strip portion 10 and the vertical groove portion 11 can be released, and the drainer 2 can be rotated with respect to the attachment port member 1. However, when the drain plug 5 is attached to the drainer 2, the engaging claw 3 cannot be bent, and the teeth of the vertical stripe portion 10 and the vertical groove portion 11 cannot be released, so that the drainer 2 Can no longer be rotated with respect to the attachment port member 1. That is, it has an angle fixing mechanism.
As described above, the drainage pipe of the embodiment shown in FIGS. 6 and 7 is an angle regulating means for regulating the range of the drainage device 2 in the angular direction with respect to the attachment port member 1, and cannot be rotated after the construction is completed. It is a drainage pipe equipped with an angle fixing mechanism.

また、上記各実施例では、排水器２と排水栓５は螺合または嵌合により接続されていたが、図示しないＣ字リングを使用し、排水器２と排水栓５を挟持することによって接続される等、種々の方法が採用されても良いものである。 Further, in each of the above embodiments, the drainage device 2 and the drain plug 5 are connected by screwing or fitting, but they are connected by sandwiching the drain device 2 and the drain plug 5 using a C-shaped ring (not shown). Various methods may be adopted.

また、上記各実施例では、係合爪３は排水器２に設けられていたが、本発明はこれに限られるものではなく、排水栓５に係合爪３が形成されていても良い。この場合、排水栓５に形成された係合爪３が取付口１ａに形成された段部１ｂ又は溝部１ｃに着脱可能に係合されることで取付口１ａに仮止めされ、その後、排水器２によって取付口１ａに対して回動自在に取り付けが行われるものである。 Further, in each of the above embodiments, the engaging claw 3 is provided in the drainage device 2, but the present invention is not limited to this, and the engaging claw 3 may be formed in the drain plug 5. In this case, the engaging claw 3 formed on the drain plug 5 is detachably engaged with the step portion 1b or the groove portion 1c formed on the mounting port 1a to be temporarily fixed to the mounting port 1a, and then the drainage device. 2 is rotatably attached to the attachment port 1a.
