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 more particularly to a drainage device mounting structure capable of easily performing a drainage device mounting operation.

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 in drainage equipment such as bathtubs, washstands, sinks, showcases, etc., a drainage device provided with a drainage outlet is attached to the bottom of the tank body, etc. A method of discharging waste water to the sewage side through a piping member is widely known.
Below, an example of this drainage device is demonstrated.
The drainage device described in Patent Document 1 is a drainage device that drains condensed water in a low-temperature showcase that displays products while maintaining the product shelf on a low temperature,
A mounting opening provided on the bottom of the low temperature showcase;
A drainage unit having a bottomed cylindrical shape and a flange portion provided at the peripheral edge of the upper opening, a male screw provided below the side surface, a discharge port bent from the bottom surface to the side and directed to the side,
A ring-shaped nut member having a female screw that is screwed with a male screw of the drainage device;
A trap member which is provided at the discharge port and generates a sealed trap function;
Consists of Here, the “trap function” is a function of preventing odors and pests from flowing back into the indoor side from the sewage side while maintaining drainage from the upstream side to the downstream side. In the case of the “sealed trap function”, a drainage reservoir called sealed water is formed on the drainage channel, and at least part of the drainage channel is always filled with the reservoir. This indicates the function of preventing odors and pests from flowing back upstream from the full water portion.
The drainage device configured as described above is attached to an attachment port provided on the bottom surface of the low temperature showcase and applied to the low temperature showcase in the following procedure.
First, a drainage device is inserted from above into an attachment 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 periphery of the attachment port.
Next, in order to make a watertight connection to 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 drainage unit is connected and fixed to the mounting port because the periphery of the mounting port is strongly clamped in the vertical direction by the lower surface of the flange portion of the drainage device and the upper surface of the nut member. In addition, underfloor piping is connected from the outside of the drain to the outlet, and a trap portion is arranged from the inside of the drain to the outlet to complete the construction of the drain in the low temperature showcase.
When dew from the items stored in the low-temperature showcase or condensed water from the air cooled by the cooling equipment of the low-temperature showcase is generated when using the low-temperature showcase, the drainage such as drip and dew Finally, it flows down to the drainage port on the bottom surface of the low temperature showcase, passes through the drainage port, the inside of the drainage device, the trap member arranged at the discharge port, and finally discharged from the underfloor piping to the sewage side.
Further, at this time, a sealed water is formed in a part of the flow path formed by the trap member in the discharge port to prevent the backflow of odors and pests to the indoor side.
JP2007-215799A

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 operation 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. For this reason, at the time of attachment, it is necessary to fix one side of the drainage device provided with the external thread or the nut member provided with the internal thread, and perform screwing by rotating the other. However, since the nut member is not exposed to the upper side of the bottom surface, the operation of fixing or rotating the nut member is impossible only from the upper side of the bottom surface provided with the mounting opening. It is necessary to do work.
In order to work on the drainage device from the upper side of the bottom surface provided with the mounting opening while working on the nut member from the bottom side of the bottom surface, the operator works around the nut member with one hand and bypasses the bottom surface. Then, it is necessary to work around the bottom from the top and bottom of the mounting opening, such as working on the drainage device with the other hand, or preparing two workers, and the mounting work becomes difficult.
In addition, when working from both the drain and the nut member from the bottom of the bottom surface provided with a mounting opening, there is no need to bypass the bottom surface as described above, but there is no need for equipment such as a bathtub or a showcase. The space between the bottom surface and the floor surface on which the equipment is installed is narrow, and in this narrow portion, the operation of fixing one of the drainer and the nut member and rotating the other is also difficult.
Moreover, in the drainage device described in Patent Document 1, the direction of the drainage device could not be adjusted after the installation of the drainage device was completed. As mentioned above, when the discharge port is provided facing the side of the drainage, it is necessary to point it in the direction of the discharge port in accordance with the position and direction of the downstream piping such as the underfloor piping to be connected. . However, in the case of the conventional drainage device described in Patent Document 1, the flange portion and the nut member of the drainage device are screwed together, and the attachment is performed by strongly holding the peripheral edge of the attachment port, and the packing disposed between them. Is pressed from above and below to ensure watertightness. For this reason, even if it tried to rotate a drainage device after completion of attachment of a drainage device and to adjust a direction, the drainage device could not contact a peripheral edge of an attachment mouth, and could not rotate. Further, if the screwing is weak enough to rotate the drainage device, the packing may not be sufficiently pressed, and water leakage may occur.
The present invention has been invented in view of the above problems, and provides a drainage mounting structure that is easy to mount and can be adjusted in direction without leakage even after completion of construction. .

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, construction is performed in the following procedure.
First, on the bottom surface B of the low temperature showcase SC, the drainage device 2 is inserted from below the attachment port 1a with the engaging claw 3 facing upward (the attachment port 1a side). When the drainage device 2 is inserted into the attachment port 1a, when the claw portion 3b of the engagement claw 3 passes through the inner surface of the step portion 1b, the rib portion 3a is once bent to the inner peripheral side (inner side) due to resin elasticity. By reducing the diameter and further raising the claw portion 3b, the claw portion 3b rides over the stepped portion 1b beyond the stepped portion 1b, and the stepped portion 1b engages with the engaging claw 3.
In a state where the claw portion 3b rides over the step portion 1b beyond the step portion 1b, the upper surface of the flange portion 2b of the drainage device 2 is substantially in contact with the lower surface of the attachment port 1a (the upper surface of the flange portion 2b and the attachment port). There may be a slight gap between the lower surface of the la and la, but there will be no problem as will be described later.) The drainage device 2 is attached unless the rib portion 3a of the engaging claw 3 is bent to the inner peripheral side. Although rotation is possible with respect to the opening | mouth 1a, it will be in the state which does not remove or move up and down. In this state, the drainage device 2 is attached to the attachment port 1a, but the engagement of the engagement claw 3 is easy to release, and the attachment is surely performed to withstand actual use as the drainage device 2. This is called “temporarily fixed state”.
From this temporarily fixed state, the drain plug 5 is inserted into the receiving part 2a above the drainage device 2 from above with respect to the bottom surface B of the low temperature showcase SC. At this time, the drain plug 5 is inserted into the receiving portion 2a and rotated, so that the male screw portion 7b of the drain plug 5 and the female screw portion 7a of the receiving portion 2a are screwed together, and the drain plug 5 is removed from the drainage device 2. It is permanently connected.
In a state where the drain plug 5 is connected to the receiving portion 2a of the drainage device 2, a state in which the outer surface of the drain plug 5 abuts against a rib piece of the engaging claw 3, or a slight gap, but the claw portion 3b. Before it bends to the inner peripheral side so as to be removed from the stepped portion 1b, it cannot contact the outer surface of the drain plug 5 and cannot be bent further to the inner peripheral side. 2 cannot be removed from the mounting opening 1a.
Next, a downstream drainage pipe is connected to the outlet 2d of the drainage device 2. At this time, an adhesive or the like is used, or a watertight connection using screws and packing is used, and the connection is surely performed so that water leakage does not occur. Also, when the connection is made, if the discharge port 2d of the drainage device 2 is not oriented in an appropriate direction for the connection of the underfloor piping, the drainage device 2 is rotated with respect to the attachment port 1a to adjust the direction. Do. In the present invention, the drainage device 2 is not pulled out of the mounting port 1a because, as in the conventional example, the periphery of the mounting port 1a is tightened up and down so that the surfaces strongly come into contact with each other and cannot be rotated. This is not because the engaging claw 3 can be bent to the inner peripheral side, and it is impossible to remove the drainage device 2 from the attachment port 1a. There is no place that is so strong that it cannot move. The O-ring O arranged in the concave portion 2c is between the concave portion 2c of the drainage device 2 and the mounting port 1a, and is strong enough to maintain watertightness. The width of the gap in the side surface direction of the drainage device 2 (or the recess portion 2c of the drainage device 2) and the mounting port 1a and the dimension of the O-ring O arranged therebetween are determined by the designer. Can always secure and maintain the desired width and size, so that “the width between the drainage 2 and the mounting opening 1a, and the O-ring that produces a contact that allows rotation while ensuring watertightness” By designing each member to the dimension “O”, the drainage device 2 can be rotated with respect to the attachment port 1a even after the drainage device 2 is attached to the attachment port 1a. It is possible to adjust 2d in a direction convenient for pipe connection.
Next, the fitting groove 8b of the deodorizing cylinder 8 is fitted to the protruding portion 5b inside the drain plug 5 for connection. At this time, after inserting the deodorizing cylinder 8 into the drain port 4, the deodorizing cylinder 8 is rotated in the screwing tightening direction so that the fitting groove 8 b and the protruding portion 5 b are fitted, and the drain port 4. It is fitted and fixed inside. Further, since the rotation operation of the deodorizing cylinder 8 is performed by gripping the handle portion 8a of the deodorizing cylinder 8, it can be rotated more easily than by gripping and rotating a member with little unevenness such as the drain plug 5. In addition, it is easy to apply the operator's force when rotating. For this reason, when the rotation of the deodorizing cylinder 8 is advanced, the drain plug 5 rotates together with the deodorizing cylinder 8, and the drainage device 2 and the drain plug 5 may be further screwed together. In this case, the drainage device 2 and the drainage plug 5 are more firmly connected, and the drainage device 2 is more preferably connected.

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 on the bottom surface B of the low temperature showcase SC by a drip from an item stored in the low temperature showcase SC or by a cooling device for the low temperature showcase SC. When condensed water from the generated air is generated, the drainage such as drip and condensed 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 deodorizing cylinder. 8 passes through and accumulates in the Owan portion 2f. When the amount of drainage becomes sufficient, the drainage (sealed water) accumulated in the Owan portion 2f flows over the upper end of the sealing wall 2e to the discharge port 2d, and is discharged from the discharge port 2d to the sewage side through the downstream pipe.
Further, in this embodiment, there is no arrangement of a watertight member between the lower surface of the flange portion 5a and the upper surface of the peripheral edge of the mounting port 1a, and no strong contact that eliminates a gap is performed. In some cases, not the drain port 4 but the lower surface of the flange portion 5a and the upper surface of the mounting port 1a. Even in this case, between the engaging claw 3 of the drainage device 2 and the inner surface of the mounting port 1a, between the lower surface of the flange portion 5a and the upper surface of the mounting port 1a, the upper edge of the drainage device 2 and the inner surface of the drainage device 2 It passes between the outer surfaces of the deodorizing cylinder 8 in order, and finally flows into the deodorizing 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 downstream piping. It is discharged toward.
Further, since the drainage is accumulated 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 is formed. , Always full. Since the sewage side odors and pests cannot pass through the full portion of this flow path, the sewage side odors and pests cannot enter the indoor side. Thus, the drainage device 2 of the present embodiment has a trap function that prevents odors and pests from entering the indoor side. That is, the present embodiment is a drainage trap provided with a trap portion including the deodorizing cylinder 8 and the 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 the trap function configured as described above does not need to work on both the upper side and the lower side of the attachment port 1 a at the same time. The drainage device 2 can be attached by only one of the above-mentioned work and the work from the lower side only, and it is necessary to perform the work simultaneously from both the upper side and the lower side. Compared with 2, installation work is extremely easy.
Further, as described in the above embodiment, the watertight connection between the drainage device 2 and the attachment port 1a is performed by the connection using the O-ring O in the lateral direction without pressing in the vertical direction. Consists of. Thereby, even after the drainage device 2 is attached, it is possible to adjust the direction by rotating the drainage device 2 relative to the attachment port 1a.
As described above, since the flange portion 5a and the periphery of the attachment 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 periphery of the attachment port 1a. The drainage that has entered the gap is stopped by the O-ring O disposed between the drainage device 2 and the attachment port 1a, and water leaks to the lower surface of the bottom surface B of the low-temperature showcase SC. Without draining, the water is discharged into the deodorizing cylinder 8 through the water passage hole 8c and discharged to the downstream side together with the waste water from the drain port 4 without any trouble.

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。

The engaging claw 3 includes a rib portion 3a extending upward from the upper end of the cylindrical portion of the drainage device 2 main body, and a claw portion 3b protruding outward from the upper end of the rib portion 3a. The engaging claw 3 is bent by the rib portion 3a, so that the claw portion 3b is reduced in diameter, becomes smaller than the diameter of the opening portion of the groove portion 1c, and the claw portion 3b can pass therethrough. When the portion 3a is not bent, the tip of the claw portion 3b has a larger diameter than the diameter of the opening portion of the groove portion 1c. Therefore, the claw portion 3b of the engagement claw 3 is fitted into the groove portion 1c, and the engagement claw 3 is the groove portion. Engage 1c.

Further, the upper end of the tube portion is provided with a flange portion 5a that protrudes outward at an angle of about 45 degrees along the entire periphery. The flange portion 5a is tapered toward the outer peripheral side of the cross section, and its outer diameter is slightly larger than the inner diameter of the mounting port 1a when no stress is applied.
When the construction is completed, the front end (outer edge portion) of the flange portion 5a is slightly bent toward the inner diameter side due to resin elasticity, so that the flange portion 5a comes into contact with the inner surface of the mounting port 1a with almost no gap. With this configuration, the drain port 4 is formed above the flange portion 5 a of the drain plug 5 by the attachment port 1 a and below by the drain plug 5.
Further, on the outer peripheral surface, apart from the fitting portion 6a, there is provided a guide rib 9b which is a rib piece facing in the vertical direction and accommodated in the guide groove 9a of the drain plug 5 (in FIG. Since it is on the back side of the drain plug 5, it is indicated by a dotted line). By fitting the guide rib 9b in the guide groove 9a, the drain plug 5 cannot be rotated with respect to the drainage device 2 when the construction is completed.
Further, inside the cylindrical portion of the drain plug 5, four protrusions 5 b are provided every 90 degrees at the same height as viewed from the side and viewed from the central axis in plan view.

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, construction is performed in the following procedure.
First, on the bottom surface B of the low temperature showcase SC, the drainage device 2 is inserted from below the attachment port 1a with the engaging claw 3 facing upward (the attachment port 1a side). When the drainage device 2 is inserted into the attachment port 1a, the claw portion 3b of the engagement claw 3 comes into contact with the inner peripheral surface of the attachment port 1a, and the rib portion 3a once bends to the inner peripheral side (inside) due to resin elasticity. Reduce the diameter with. If it raises as it is, the nail | claw part 3b will reach | attain the groove part 1c, and the groove part 1c will engage with the engaging claw 3 by the nail | claw part 3b fitting in the groove part 1c.
In a state where the claw portion 3b is fitted in the groove portion 1c, the drainage device 2 can rotate with respect to the attachment port 1a as long as the rib portion 3a of the engagement claw 3 is not bent toward the inner peripheral side. It will be in a state where it cannot be removed or moved up and down. In this state, the drainage device 2 is attached to the attachment port 1a, but the engagement of the engagement claw 3 is easy to release, and the attachment is surely performed to withstand actual use as the drainage device 2. This is called “temporarily fixed state”.
From this temporarily fixed state, the drain plug 5 is inserted into the receiving part 2a above the drainage device 2 from above with respect to the bottom surface B of the low temperature showcase SC. At this time, by adjusting the position so that the guide rib 9b of the drain plug 5 fits into the guide groove 9a of the receiving portion 2a and inserting the drain plug 5 into the receiving portion 2a without rotating from above as it is. By fitting the fitted portion 6b of the drain plug 5 to the fitting portion 6a of the drainage device 2 in a state in which the drainage plug 5 cannot be removed, the drain plug 5 is connected to the drainage device 2 so as not to be removable. The At this time, the distal end portion of the flange portion 5a of the drain plug 5 enters the attachment port 1a, bends slightly to the inner diameter side due to resin elasticity, and is in contact with the inner surface of the attachment port 1a with almost no gap.
In addition, the guide rib 9 b of the drain plug 5 is housed in the guide groove 9 a of the drain device 2, and the drain plug 5 cannot be rotated with respect to the drain device 2. It is only impossible to rotate the drain plug 5 with respect to the drainage device 2, and the drainage device 2 can be rotated with respect to the attachment port 1a.
In a state where the drain plug 5 is connected to the receiving portion 2a of the drainage device 2, a state in which the outer surface of the drain plug 5 abuts against a rib piece of the engaging claw 3, or a slight gap, but the claw portion 3b. Before it bends to the inner peripheral side so as to be removed from the groove 1c, it is in a state in which it cannot contact the outer surface of the drain plug 5 and bend further to the inner peripheral side. Cannot be removed from the mounting opening 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 some play space, the drainage device 2 is simply removed from the mounting port 1a. Not only becomes impossible to remove, but also the drainage device 2 does not extremely move up and down from the attachment port 1a.
Next, a downstream drainage pipe is connected to the outlet 2d of the drainage device 2. At this time, an adhesive or the like is used, or a watertight connection using screws and packing is used, and the connection is surely performed so that water leakage does not occur. Also, when the connection is made, if the discharge port 2d of the drainage device 2 is not oriented in an appropriate direction for the connection of the underfloor piping, the drainage device 2 is rotated with respect to the attachment port 1a to adjust the direction. Do. In the present invention, the drainage device 2 is not pulled out of the mounting port 1a because, as in the conventional example, the periphery of the mounting port 1a is tightened up and down so that the surfaces strongly come into contact with each other and cannot be rotated. This is not because the engaging claw 3 can be bent to the inner peripheral side, and it is impossible to remove the drainage device 2 from the attachment port 1a. There is no place that is so strong that it cannot move.
More specifically, the contact between the front end of the flange portion 5a of the drain plug 5 and the attachment port 1a is the contact portion at the front end of the flange portion 5a, the area is small, 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 water tightness. Although it is generated between the mouth 1a, the width of the gap in the side surface direction of the drainage device 2 (or the recessed portion 2c of the drainage device 2) and the mounting port 1a, and the dimension of the O-ring O arranged between them, Since the designer can always secure and maintain a certain width and size desired by the designer, “the width between the drainage device 2 and the mounting port 1a, which produces a contact that allows rotation while ensuring watertightness, and By designing each member to “dimension of O-ring O”, the drainage device 2 can be rotated with respect to the attachment 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 to the protruding portion 5b inside the drain plug 5 for connection. At this time, after inserting the deodorizing cylinder 8 into the drain port 4, the deodorizing cylinder 8 is rotated so that the fitting groove 8 b and the protruding portion 5 b are fitted and fitted into the drain port 4. The At this time, since the guide rib 9b fits into the guide groove 9a, the drain plug 5 cannot rotate with respect to the drainage device 2, and the drain plug 5 rotates integrally with the deodorizing cylinder 8. Thus, the occurrence of so-called rotation that prevents the rotation from being fitted to the end is prevented. At the time of attaching the deodorizing cylinder 8, the discharge port 2d of the drainage device 2 is connected to the underfloor piping, the direction is fixed by the underfloor piping, and the drainage device 2 also rotates together with the drain plug 5 and the deodorizing tube 8. There is no such thing.

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 on the bottom surface B of the low temperature showcase SC by a drip from an item stored in the low temperature showcase SC or by a cooling device for the low temperature showcase SC. When condensed water from the generated air is generated, the drainage such as drip and condensed 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 deodorizing cylinder. 8 passes through and accumulates in the Owan portion 2f. When the amount of drainage becomes sufficient, the drainage (sealed water) accumulated in the Owan portion 2f flows over the upper end of the sealing wall 2e to the discharge port 2d, and is discharged from the discharge port 2d to the sewage side through the downstream pipe.
Further, in this embodiment, there is no arrangement of a watertight member between the lower surface of the flange portion 5a and the upper surface of the peripheral edge of the mounting port 1a, and no strong contact that eliminates a gap is performed. In some cases, not the drain port 4 but the lower surface of the flange portion 5a and the upper surface of the mounting port 1a. Even in this case, between the engaging claw 3 of the drainage device 2 and the inner surface of the mounting port 1a, between the lower surface of the flange portion 5a and the upper surface of the mounting port 1a, the upper edge of the drainage device 2 and the inner surface of the drainage device 2 Passes between the outer surfaces of the deodorizing cylinder 8 and finally flows into the deodorizing 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 flows into the downstream pipe. It is discharged towards.
Further, since the drainage is accumulated 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 is formed. , Always full. Since the sewage side odors and pests cannot pass through the full portion of this flow path, the sewage side odors and pests cannot enter the indoor side. Thus, the drainage device 2 of the present embodiment has a trap function that prevents odors and pests from entering the indoor side. That is, the present embodiment is a drainage trap provided with a trap portion including the deodorizing cylinder 8 and the 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 the trap function configured as described above does not need to work on both the upper side and the lower side of the attachment port 1 a at the same time. The drainage device 2 can be attached by only one of the above-mentioned work and the work from the lower side only, and it is necessary to perform the work simultaneously from both the upper side and the lower side. Compared with 2, installation work is extremely easy.
Further, as described in the above embodiment, the watertight connection between the drainage device 2 and the attachment port 1a is performed by the connection using the O-ring O in the lateral direction without pressing in the vertical direction. Consists of.
Further, the contact between the front end of the flange portion 5a of the drain plug 5 and the attachment port 1a is also difficult to prevent rotation of the drainage device 2 with respect to the attachment port 1a because the area of the contact portion is small and watertightness is not ensured. No.
Thereby, even after the drainage device 2 is attached, it is possible to adjust the direction by rotating the drainage device 2 relative to the attachment port 1a.
In this way, since the flange portion 5a and the attachment port 1a are not strongly pressed, drainage enters between the front end of the flange portion 5a and the attachment port 1a and spreads so that part of the drainage is attached to the drain plug 5. Although there is a possibility of flowing into the gap of the mouth 1a, the drainage that has entered the gap is also stopped by the O-ring O disposed between the drainage device 2 and the attachment port 1a, and the bottom surface of the low temperature showcase SC. Without leaking to the lower surface of B, the water is discharged into the deodorizing cylinder 8 through the water passage hole 8c, and discharged to the downstream side together with the drainage from the drainage port 4 without any trouble.

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。
The embodiments of the present invention are as described above. However, the present invention is not limited to the above-described embodiments, and can be freely changed without departing from the scope of the present invention.
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 drainage port 4 of a wash basin, a sink, a bathtub or a bathroom. It may be adopted for 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 outlet, and may be attached to an overflow channel or the like of the washstand.

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。   Moreover, in each said Example, after attaching the drainage device 2 to the attachment port 1a, after adjusting the direction of the drainage device 2, the underfloor piping is connected to the discharge port 2d, but this invention is the said Example. However, the procedure may be changed, and after connecting the underfloor piping to the discharge port 2d first, the drainage device 2 may be attached to the mounting port 1a.

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 mounting opening 1a. However, by providing an angle regulating means or the like, it can freely rotate 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 be rotated when the construction is completed. In this case, workability can be improved by preventing the drainage device 2 from rotating in an unexpected direction after the direction of the drainage device 2 is determined.
The embodiment shown in FIGS. 6 and 7 is a drainage pipe provided with the angle restricting means and an angle fixing mechanism that cannot be rotated after the completion of construction. Specifically, in the drainage device of the first embodiment, as the angle regulating means and the angle fixing mechanism, the triangular vertical stripe portion 10 is provided only on a part of the claw part 3b, and the claw is provided only on a part of the attachment part 1a. A longitudinal groove portion 11 corresponding to the longitudinal stripe portion 10 of the portion 3b is provided. As apparent from FIG. 7, in the AA sectional view of FIG. 6, the range having the longitudinal 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 where the vertical groove portion 11 is not provided.
For this reason, the vertical strip portion 10 of the claw portion 3b can be disposed 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 drainage device 2 is merely fitted to the attachment port member 1, although the vertical strip portion 10 and the vertical groove portion 11 are engaged, the elasticity of the rib portion 3 a of the engaging claw 3 is used. Thus, the engaging claw 3 can be bent to release the meshing between the vertical strip portion 10 and the vertical groove portion 11, and the drainage device 2 can be rotated with respect to the attachment port member 1. However, when the drain plug 5 is attached to the drainage device 2, it becomes impossible for the engaging claw 3 to bend, and it becomes impossible to release the engagement between the vertical stripe portion 10 and the vertical groove portion 11, and the drainage device 2 Cannot 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 FIG. 6 and FIG. 7 is an angle regulating means for regulating the range in the angular direction of the drainage device 2 with respect to the attachment port member 1 and cannot be rotated after the construction is completed. It is a drainage pipe provided 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。   Moreover, in each said Example, although the drainage device 2 and the drain plug 5 were connected by screwing or fitting, it connected by clamping the drainage device 2 and the drain plug 5 using the C-shaped ring which is not illustrated. For example, 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。   Moreover, in each said Example, although the engaging claw 3 was provided in the drainage device 2, this invention is not restricted to this, The engaging claw 3 may be formed in the drain plug 5. FIG. In this case, the engaging claw 3 formed in the drain plug 5 is temporarily fixed to the mounting port 1a by being detachably engaged with the step portion 1b or the groove portion 1c formed in the mounting port 1a. 2 is attached to the attachment port 1a so as to be rotatable.
