Description

【0001】
【発明の属する技術分野】
この発明は、浴室ユニットにおける排水構造に関するものである。
【0002】
【従来の技術】
従来、浴室のドア下の排水構造は、例えば特許文献1に開示されているように、ドア下から配管をトラップに直接つなぐ構造となっている。
【0003】
【特許文献1】
特開2000−54450号公報
【0004】
【発明が解決しようとする課題】
従来では、逆流や封水等の品質面や構造が複雑になることによるコスト面でのデメリットがあった。
【0005】
【課題を解決するための手段】
本発明は、上記従来の問題点に鑑み案出したものであって、排水構造を簡略化することができ、低コストでドア下配管や追焚き水受け配管を排水口に導くことのできる浴室ユニットの排水構造を提供せんことを目的とし、その第1の要旨は、防水パンの洗い場側に形成された排水溝または排水桝の立ち面に貫通孔を設け、該貫通孔に、二股に分岐した継手金具を直接取り付けるとともに、該継手金具に対し、ドア下からの排水配管と、追焚き水受けからの排水配管を接続することである。
【0006】
また、第2の要旨は、防水パンは、洗い場側の洗い場パンと浴槽側の浴槽パンに分割されているとともに、前記洗い場パンに一体形成された排水溝または排水桝の前記浴槽パン側の立ち面に貫通孔を設けて、該貫通孔に、二股状に分岐した継手金具を直接取り付け、該継手金具に対し、ドア下からの排水配管と、追焚き水受けからの排水配管を接続することである。
【0007】
【発明の実施の形態】
以下、本発明の実施例を図面に基づいて説明する。
図1は、浴室の斜視構成図であり、浴室1の底面を構成する防水パン2は、洗い場となる洗い場パン3と、浴槽を設置する浴槽パン4が分割されて形成されており、洗い場パン3の浴槽パン4側には、下方へ凹み状に排水桝5が一体形成されている。
【0008】
図2の要部拡大斜視図で示すように、洗い場パン3の排水桝5の外側には、上方へ一体状に立ち上げて立上部3aが形成され、立上部3aの下端から浴槽パン4側へ略水平に延びて水平片部3bが一体形成されている。
一方、浴槽パン4側には、洗い場パン3の水平片部3b上に載置させて浴槽パン4を接続できる接続部4aが形成されている。
前記排水桝5は、水平片部3bよりも下方側へ突出して凹み状に一体形成されており、この排水桝5の底面には底孔5bが形成され、その下部には、別体のトラップ6が設けられている。
【0009】
このトラップ6の上方の排水桝5の浴槽パン4側の立ち面5aに、継手金具7が直接取り付けられている。この拡大図を図3に示し、また図4には、平面拡大図を示す。更に図5では、継手金具7の部品構成を斜視図で示す。
継手金具7は、外周にネジ7bを有する基管部7aの先端に、直交状に分岐管部7cが設けられて略T字状に形成されており、分岐管部7cの両端内側には、接続用ネジ部7dが形成されている。
前記排水桝5の浴槽パン4側の立ち面5aに、予め貫通孔12を形成させておき、この貫通孔12内に、継手金具7の基管部7aを挿通させ、鍔7eを立ち面5aに当接させて、排水升5の内側から、基管部7aの外周にパッキン13およびスリップワッシャー14を外嵌させて、基管部7aのネジ7bに対しロックリング15を締め付け、このロックリング15により、立ち面5aに継手金具7を直接取り付けることができるものである。
【0010】
なお、この継手金具7を排水桝5に取り付ける作業は、浴槽パン4を洗い場パン3に接続する前であり、しかも、排水桝5は水平片部3bよりも下方へ突出しているため、浴槽パン4および水平片部3bが邪魔にならず、良好かつ容易に継手金具7を排水桝5に取り付けることができるものである。
この継手金具7の分岐管部7cの両端には、ドア下排水配管8と、追焚き水受け排水配管9がそれぞれ対向状に接続されるものである。
ドア下排水配管8は、浴室1のドア10の下部に溜まる水を、水受け11から排水桝5内に流入させるためのものである。
【0011】
また、追焚き水受け排水配管9は、図6,図7に示すように、浴槽パン4に設置される浴槽16(図6では、浴槽パン4に浴槽16が一体形成されているタイプを示している。また図7は、図6の要部拡大図である。)の側面に形成された追焚き用の追焚き口16aから漏れる水を、追焚き口16aに取り付けられた水受け17で受けて、この水受け17からの排水を排水桝5に導くものである。
図7において、水受け17には接続管17aが突出されており、この接続管17aに対し、追焚き水受け排水配管9を差し込み状に接続して、外周をクリップ18で締め付けて容易に接続できるものである。
継手金具7に対し、ドア下排水配管8および追焚き水受け排水配管9を接続した後に、洗い場パン3に対し浴槽パン4を接続することができる。
【0012】
このように本例では、洗い場パン3に一体形成された排水桝5に、継手金具7を介してドア下排水配管8および追焚き水受け排水配管9を接続する構成であるため、トラップ6よりも上方の排水桝5に排水配管をつなぐことができ、従来のような逆流や封水等の品質面や構造が複雑になることがなく、排水構造を簡略化することができ、低コストで、ドア下からの排水および追焚き口16aからの排水を排水桝5に導いて排水することができるものである。
【0013】
また、洗い場パン3の排水桝5に排水されるものであり、この排水桝5は掃除が簡単に行え、従来のようにトラップを掃除することに比べると、掃除作業が容易なものとなる。
また、継手金具7を直接排水桝5に取り付けているため、点検口から容易に、継手金具7の部分、およびドア下排水配管8および追焚き水受け排水配管9の接続部を点検することができ、メンテナンスも容易なものとなる。
【0014】
なお、浴槽パン4が洗い場パン3と分割されているタイプにおいては、浴槽パン4を取り外した状態で、排水桝5の立ち面5aに貫通孔12を開口させる作業を楽に行うことができ、継手金具7の取付作業も容易に行うことができ、その後に浴槽パン4を接続でき、作業が容易なものとなる。
また、配管途中で分岐管を使用する場合とは異なり、排水桝5に直接接続金具7を取り付けて、排水配管8,9を接続するものであるため、接続する箇所が集中しており、接続部が少なくなるため、組み付け工程が少なく、漏水の危険性も少ないものとなる。
【0015】
なお、本例では、洗い場パン3に排水桝5を一体で形成させた場合を例示しているが、排水桝5に代えて、洗い場パン3に排水溝を一体に形成して、この排水溝の浴槽パン4側の立ち面に、継手金具7を直接取り付けて構成することもできるものである。
【0016】
【発明の効果】
本発明の浴室ユニットの排水構造は、防水パンの洗い場側に形成された排水溝または排水桝の立ち面に貫通孔を設け、貫通孔に、二股に分岐した継手金具を直接取り付けるとともに、継手金具に対し、ドア下からの排水配管と、追焚き水受けからの排水配管を接続することとしたため、トラップよりも高い位置にある排水溝または排水桝の立ち面に、直接継手金具を取り付けて、排水管を接続することができ、排水構造を簡略化することができ、しかも排水桝または排水溝の掃除も容易となる。
また、継手金具に対し、ドア下からの排水配管と、追焚き水受けからの排水配管を同時に接続させることができ、接続箇所が1ヶ所で済み、接続部が少なくなって漏水の危険性が少なくなり、組み付け作業も容易なものとなる。
【0017】
また、防水パンは、洗い場側の洗い場パンと浴槽側の浴槽パンに分割されているとともに、洗い場パンに一体形成された排水溝または排水桝の浴槽パン側の立ち面に貫通孔を設けて、貫通孔に、二股状に分岐した継手金具を直接取り付け、継手金具に対し、ドア下からの排水配管と、追焚き水受けからの排水配管を接続することとしたため、浴槽パンを取り外した状態で、良好に排水溝または排水桝の立ち面に貫通孔を開ける作業を行うことができ、更に、貫通孔に対し良好に継手金具を取り付け、また継手金具に対し、ドア下からの排水配管および追焚き水受けからの排水配管を同時に1ヶ所で接続して、配管の接続作業も極めて容易に行うことができ、その後に、浴槽パンを洗い場パンに接続して作業を完了することができるものとなる。

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective configuration view of a bathroom. A waterproof pan 2 constituting a bottom surface of a bathroom 1 is formed by dividing a washing pan 3 serving as a washing place and a bath pan 4 providing a bathtub. A drain basin 5 is formed integrally with the bathtub pan 4 side 3 in a downwardly concave shape.
[0008]
As shown in the enlarged perspective view of the main part in FIG. 2, a rising part 3a is integrally formed on the outside of the drainage basin 5 of the washing pan 3, and is integrally raised upward. The horizontal piece 3b extends substantially horizontally and is integrally formed.
On the other hand, on the side of the bathtub pan 4, a connection portion 4 a that can be placed on the horizontal piece 3 b of the washing pan 3 and connected to the bathtub pan 4 is formed.

A fitting 7 is directly attached to a standing surface 5a of the drainage tub 5 above the trap 6 on the side of the bathtub pan 4. This enlarged view is shown in FIG. 3, and FIG. 4 is an enlarged plan view. Further, FIG. 5 is a perspective view showing a component configuration of the fitting 7.
The joint fitting 7 is formed in a substantially T-shape with a branch pipe section 7c provided orthogonally at the tip of a base pipe section 7a having a screw 7b on the outer periphery, and inside the both ends of the branch pipe section 7c, A connection screw portion 7d is formed.
A through-hole 12 is formed in advance on the standing surface 5a of the drainage basin 5 on the side of the bathtub pan 4, and the base pipe portion 7a of the fitting 7 is inserted into the through-hole 12 so that the flange 7e is connected to the rising surface 5a. , The packing 13 and the slip washer 14 are externally fitted to the outer periphery of the base tube portion 7a from the inside of the drainage box 5, and the lock ring 15 is fastened to the screw 7b of the base tube portion 7a. 15 allows the fitting 7 to be directly attached to the standing surface 5a.
[0010]
The work of attaching the fitting 7 to the drainage basin 5 is before the bathtub pan 4 is connected to the washing pan 3, and the drainage basin 5 projects below the horizontal piece 3b. 4 and the horizontal piece 3b do not become an obstacle, and the fitting 7 can be attached to the drainage basin 5 satisfactorily and easily.
A drain pipe 8 under the door and a drain pipe 9 for reheating water are connected to both ends of the branch pipe portion 7c of the joint fitting 7 so as to face each other.
The drain pipe 8 below the door is for letting water accumulated in the lower part of the door 10 of the bathroom 1 flow into the drain basin 5 from the water receiver 11.
[0011]
Further, as shown in FIGS. 6 and 7, the additional heating water receiving and draining pipe 9 is a bathtub 16 installed in the bathtub pan 4 (in FIG. 6, the bathtub 16 is integrally formed with the bathtub pan 4). FIG. 7 is an enlarged view of a main part of FIG. 6.) Water leaking from a reheating port 16a formed on the side surface of the reheating tank 16 is formed by a water receiver 17 attached to the reheating port 16a. The drainage from the water receiver 17 is guided to the drainage basin 5.
In FIG. 7, a connecting pipe 17a is projected from the water receiver 17, and a reheating water receiving / draining pipe 9 is connected to the connecting pipe 17a in a plug-in manner, and the outer periphery is fastened by a clip 18 for easy connection. You can do it.
After connecting the drainage pipe 8 under the door and the drainage pipe 9 for reheating water to the fitting 7, the bathtub pan 4 can be connected to the washing pan 3.

Thus, in this example, since the drainage pipe 5 under the door and the drainage pipe 9 for reheating water are connected to the drainage basin 5 integrally formed with the washing pan 3 via the joint fitting 7, the trap 6 The drainage pipe can be connected to the drainage basin 5 above, so that the quality and structure such as the backflow and the sealing of water are not complicated as in the past, the drainage structure can be simplified, and the cost can be reduced. The drainage from under the door and the drainage from the reheating port 16a can be guided to the drainage basin 5 for drainage.
[0013]
Further, the drainage basin 5 is drained into the drainage basin 5 of the washing pan 3, and the drainage basin 5 can be easily cleaned, and the cleaning work is easier than the conventional case of cleaning the trap.
In addition, since the fitting 7 is directly attached to the drainage basin 5, it is easy to inspect the fitting 7 and the connection between the drainage pipe 8 under the door and the drainage pipe 9 for reheating water from the inspection port. It is possible and maintenance becomes easy.
[0014]
In the type in which the bathtub pan 4 is separated from the washing pan 3, the work of opening the through hole 12 in the standing surface 5a of the drainage basin 5 can be easily performed with the bathtub pan 4 removed. The mounting work of the metal fittings 7 can be easily performed, and thereafter, the bathtub pan 4 can be connected, which facilitates the work.
Also, unlike the case where a branch pipe is used in the middle of the pipe, the connection fitting 7 is directly attached to the drainage basin 5 and the drainage pipes 8 and 9 are connected. Since the number of parts is reduced, the number of assembling steps is reduced, and the risk of water leakage is reduced.
[0015]
In addition, in this example, the case where the drainage basin 5 is formed integrally with the washing pan 3 is illustrated. However, instead of the drainage basin 5, a drainage ditch is integrally formed with the washing pan 3 and the drainage ditch is formed. The joint fitting 7 can be directly attached to the standing surface of the bathtub pan 4 side.
[0016]
