図８に示すように、流路形成部材（３）に設けられる弁部材（９）（９）は、合成ゴムの一体成形品をもって構成されている。この弁部材（９）（９）は、断面略「へ」の字形に形成されており、その一片が矩形板状の吐出弁（９１）として構成されるとともに、他片が矩形板状の吸込弁（９２）として構成されている。 As shown in FIG. 8, the valve members (9) and (9) provided in the flow path forming member (3) are formed of an integrally molded product of synthetic rubber. The valve members (9) and (9) are formed in a substantially “H” cross-section, one piece of which is configured as a rectangular plate discharge valve (91), and the other piece is a rectangular plate suction. It is configured as a valve (92).
図２及び図３に示すように、この弁部材（９）における吐出弁（９１）及び吸込弁（９２）間の連結部が、円盤状ケーシング（４）の前壁内面側に固定される。これにより自然状態においては、弁部材（９）（９）の吐出弁（９１）（９１）が、区画室出口（３１ａ）（３１ｂ）を吐出室（３ｃ）側から閉塞するように配置されるとともに、吸込弁（９２）（９２）が、吸込口（３２ａ）（３２ｂ）を区画室（３ａ）（３ｂ）側から閉塞するように配置される。 As shown in FIG.2 and FIG.3, the connection part between the discharge valve (91) and the suction valve (92) in this valve member (9) is fixed to the front wall inner surface side of a disk shaped casing (4). Thereby, in a natural state, the discharge valves (91) (91) of the valve members (9) (9) are arranged so as to close the compartment outlets (31a) (31b) from the discharge chamber (3c) side. At the same time, the suction valves (92) and (92) are disposed so as to close the suction ports (32a) and (32b) from the compartments (3a) and (3b) side.
こうして取り付けられた弁部材（９）（９）において、吐出弁（９１）（９１）は、その外周縁部が吐出室（３ｃ）側における区画室出口（３１ａ）（３１ｂ）の周縁部（弁座部）に弾性力により密着しており、吐出室（３ｃ）側から区画室（３ａ）（３ｂ）側に温水が流れ込もうとした際には、その水圧によって、吐出弁（９１）（９１）の区画室出口（３１ａ）（３１ｂ）に対する閉塞状態が維持されて、その方向の温水の流通が規制されるとともに、逆に、区画室（３ａ）（３ｂ）側から吐出室（３ｃ）側に温水が流れ込もうとした際には、その水圧によって、吐出弁（９１）（９１）が吐出室（３ｃ）側に揺動するように弾性変形することにより、区画室出口（３１ａ）（３１ｂ）が開放され、その方向の温水の流通が許容されるよう構成されている。従って弁部材（９）（９）の吐出弁（９１）（９１）は、吐出室（３ｃ）に対し、温水の排出方向の流通は許容し、かつ吸込方向の流通は阻止する逆止弁として機能する。 In the valve members (9) and (9) attached in this way, the discharge valve (91) (91) has a peripheral edge (valve of the partition outlets (31a) and (31b) on the discharge chamber (3c) side. When the warm water is about to flow from the discharge chamber (3c) side to the compartment (3a) (3b) side, the discharge valve (91) ( 91) is closed with respect to the compartment outlets (31a) and (31b), the flow of hot water in that direction is restricted, and conversely, from the compartment (3a) (3b) side to the discharge chamber (3c) When the hot water is about to flow into the side, the discharge pressure (91) (91) is elastically deformed so as to swing toward the discharge chamber (3c) by the water pressure, so that the compartment outlet (31a) (31b) is opened, and the flow of hot water in that direction is allowed It is configured. Accordingly, the discharge valves (91) and (91) of the valve members (9) and (9) serve as check valves that allow the warm water to flow in the discharge direction and prevent the suction direction from flowing to the discharge chamber (3c). Function.
更に弁部材（９）（９）の吸込弁（９２）（９２）は、その外周縁部が区画室（３ａ）（３ｂ）側における吸込口（３２ａ）（３２ｂ）の周縁部（弁座部）に弾性力により密着しており、区画室（３ａ）（３ｂ）側から外部に温水が流れ出そうとした際には、水圧によって、吸込弁（９２）（９２）の吸込口（３２ａ）（３２ｂ）に対する閉塞状態が維持されて、その方向の温水の流通が規制されるとともに、逆に、外部から区画室（３ａ）（３ｂ）側に温水が流れ込もうとした際には、その水圧によって、吸込弁（９２）（９２）が内側に弾性変形することにより、吸込口（３２ａ）（３２ｂ）が開放されて、その方向の温水の流通が許容されるよう構成されている。従って、弁部材（９）（９）の吸込弁（９２）（９２）は、区画室（３ａ）（３ｂ）に対し、温水の吸込方向の流通は許容し、かつ吐出方向の流通は阻止する逆止弁として機能する。 Further, the suction valves (92) and (92) of the valve members (9) and (9) have peripheral edges (valve seats) of the suction ports (32a) and (32b) on the side of the compartments (3a) and (3b). ) By elastic force, and when warm water is about to flow out from the compartments (3a) and (3b), the suction ports (32a) (32a) ( 32b) is maintained, the flow of warm water in that direction is restricted, and conversely, when warm water tries to flow into the compartments (3a) and (3b) from the outside, the water pressure is reduced. Thus, the suction valves (92) and (92) are elastically deformed inward, whereby the suction ports (32a) and (32b) are opened, and the hot water in that direction is allowed to flow. Therefore, the suction valves (92) and (92) of the valve members (9) and (9) allow passage of the hot water in the suction direction and prevent passage in the discharge direction with respect to the compartments (3a) and (3b). Functions as a check valve.

A plurality of engaging projections (not shown) project inwardly on the inner surface of the peripheral side wall corresponding to the plurality of groove-shaped grooves (37) provided on the outer peripheral surface of the flow path forming member (3). It is formed in a shape. The engaging protrusions are inserted into and engaged with the bowl-shaped grooves (37), so that the filter member (6) is detachably attached to the disc-shaped casing (4) of the flow path forming member (3). ing.
このフィルター部材（６）の前面部には、複数の吸込用開口（６１）が形成されるとともに、吸込用開口（６１）には、フィルター本体としての金属製メッシュシートが配置されている。更にフィルター部材（６）の周側壁には、流路形成部材（３）の吐出口（３５）に対応して吐出用開口（６５）が形成されている。 A plurality of suction openings (61) are formed in the front surface of the filter member (6), and a metal mesh sheet as a filter body is disposed in the suction openings (61). Further, a discharge opening (65) is formed on the peripheral side wall of the filter member (6) corresponding to the discharge port (35) of the flow path forming member (3).
次に上記浴槽用配管接続具の施工手順について説明する。なお本実施形態の施工作業は、一人の作業者で行うものである。 Next, the construction procedure for the above-mentioned bathtub pipe connector will be described. In addition, the construction work of this embodiment is performed by one worker.
まず、槽外フランジ部材（１）に２本の連結ねじ（７）（７）を少量ねじ込んで固定しておく。 First, two connecting screws (7) and (7) are screwed in a small amount into the tank outer flange member (1) and fixed.
そして図６に示すようにそのねじ付き槽外フランジ部材（１）の連結ねじ（７）（７）を、浴槽（Ｔ）の側壁外面側から浴槽孔（Ｈ）に挿通して、基板（１１）の外周端縁を浴槽壁外面側に当接させた状態で、連結ねじ（７）（７）の頭部（７２）（７２）を浴槽壁における浴槽孔（Ｈ）の周縁部に係止する。この状態では、基板（１１）の外周端縁が浴槽壁外面に係止して、ねじ頭部（７２）（７２）が浴槽孔（Ｈ）の周縁部に引っ掛かるため、槽外フランジ部材（１）は、浴槽壁に２点で支持されることになり、作業者が手を離したとしても仮保持される。 And as shown in FIG. 6, the connection screw (7) (7) of the threaded tank outer flange member (1) is inserted into the bathtub hole (H) from the side wall outer surface side of the bathtub (T), and the substrate (11 ), The heads (72) and (72) of the connecting screws (7) and (7) are locked to the peripheral edge of the bathtub hole (H) in the bathtub wall. To do. In this state, the outer peripheral edge of the substrate (11) is locked to the outer surface of the bathtub wall, and the screw heads (72) (72) are caught on the peripheral edge of the bathtub hole (H). ) Is supported by the bathtub wall at two points, and is temporarily held even if the operator releases his / her hand.
こうしてねじ付き槽外フランジ部材（１）を浴槽外側に仮保持した状態で、作業者は浴槽内側に回り込んで、浴槽内の取付作業を行う。 Thus, in a state where the threaded tank outer flange member (1) is temporarily held on the outside of the bathtub, the operator goes around the inside of the bathtub and performs the installation work in the bathtub.
すなわち図１〜３に示すように浴槽孔（Ｈ）に係止されたねじ（７）（７）を槽内側に引き込んで、そのねじ（７）（７）に槽内側から第１パッキン（８１）を外嵌する。その後、ねじ（７）（７）の頭部（７２）（７２）を槽内フランジ部材（２）の頭部挿通孔（２２）（２２）に挿通させて槽内フランジ部材（２）の前面側（槽内側）に配置する。こうしてねじ（７）（７）を槽内フランジ部材（２）に挿通配置させるとともに、その槽内フランジ部材（２）と浴槽内面との間に第１パッキン（８１）を配置する。 That is, as shown in FIGS. 1-3, the screw (7) (7) latched by the bathtub hole (H) is drawn inside the tank, and the first packing (81) is inserted into the screw (7) (7) from the inside of the tank. ). Thereafter, the heads (72) and (72) of the screws (7) and (7) are inserted into the head insertion holes (22) and (22) of the tank flange member (2), and the front surface of the tank flange member (2) is inserted. Place on the side (inside the tank). In this manner, the screws (7) and (7) are inserted and arranged in the tank flange member (2), and the first packing (81) is arranged between the tank flange member (2) and the inner surface of the bathtub.
続いて槽内フランジ部材（２）を槽外フランジ部材（１）に対し相対的に軸心回りに回転させるようにして、ねじ（７）（７）をねじ案内溝（２５）（２５）に沿って移動させて、ねじ止め孔（２３）（２３）に配置する。 Subsequently, the tank inner flange member (2) is rotated relative to the outer tank flange member (1) around the axial center so that the screws (7) and (7) become screw guide grooves (25) and (25). It moves along, and arrange | positions to a screw hole (23) (23).
ここで本実施形態においては、図７に示すように槽内フランジ部材（２）におけるねじ案内溝（２５）の途中位置に、溝幅を小さくするように戻り防止用突起部（２５ａ）を形成しているため、ねじ（７）をねじ止め孔（２３）に案内する際には、突起部（２５ａ）において溝幅を押し広げるように変形させてねじ（７）を強制的に通過させるものである。こうして突起部（２５ａ）を乗り越えたねじ（７）は、突起部（２５ａ）に係止することにより、頭部挿通孔（２２）側へ不用意に戻るのが防止されるため、ねじ（７）をねじ止め孔（２３）内に確実に配置でき、良好な作業性を得ることができる。 Here, in this embodiment, as shown in FIG. 7, a return preventing projection (25a) is formed at a midway position of the screw guide groove (25) in the tank flange member (2) so as to reduce the groove width. Therefore, when guiding the screw (7) to the screw hole (23), the protrusion (25a) is deformed so as to widen the groove width, and the screw (7) is forced to pass through. It is. The screw (7) that has overcome the protruding portion (25a) is prevented from inadvertently returning to the head insertion hole (22) side by being locked to the protruding portion (25a). ) Can be reliably disposed in the screw hole (23), and good workability can be obtained.
続いて図１〜３に示すように槽内フランジ部材（２）を第１パッキン（８１）を介して、浴槽内壁面における浴槽孔（Ｈ）の周縁部に接合しつつ、ねじ（７）（７）をドライバー等によって締め付けていく。これにより槽外フランジ部材（１）が浴槽外壁面に引き寄せられて、両フランジ部材（１）（２）が浴槽壁の孔周縁部を挟持し、両フランジ部材（１）（２）が浴槽壁に固定される。 Next, as shown in FIGS. 1 to 3, the tank flange member (2) is joined to the peripheral edge portion of the bathtub hole (H) on the inner wall surface of the bathtub via the first packing (81), and the screw (7) ( 7) Tighten with a screwdriver. As a result, the outer flange member (1) is drawn to the outer wall surface of the bathtub, both flange members (1) and (2) sandwich the peripheral edge of the hole in the bathtub wall, and both flange members (1) and (2) are the bathtub wall. Fixed to.
続いて流路形成部材（３）を、その連結パイプ（５ａ）（５ｂ）を槽内フランジ部材（２）の頭部挿通孔（２２）（２２）に挿通して、槽外フランジ部材（１）の外管接続部（１２ａ）（１２ｂ）にＯリング（１５）（１５）を介して連通接続するとともに、円盤状ケーシング（４）の後壁（４１）を槽内フランジ部材（２）に第２パッキン（８２）を介して接合した状態で、ねじ（５７）を円盤状ケーシング（４）のねじ止め孔（４７）に挿通して、槽内フランジ部材（２）のねじ止め孔（２７）に締め付けて固定する。 Subsequently, the flow path forming member (3) is inserted into the head insertion holes (22) and (22) of the tank flange member (2) through the connecting pipes (5a) and (5b), and the tank outer flange member (1) is inserted. ) Through the O-rings (15) and (15) and the rear wall (41) of the disk-shaped casing (4) to the tank flange member (2). In a state of being joined via the second packing (82), the screw (57) is inserted into the screwing hole (47) of the disk-shaped casing (4), and the screwing hole (27 of the tank flange member (2) is inserted. ) And tighten.
その後、フィルター部材（６）を流路形成部材（３）の円盤状ケーシング（４）に外嵌して固定する。これにより本実施形態の水槽用配管接続具の組付施工作業が完了する。 Thereafter, the filter member (6) is externally fitted and fixed to the disc-shaped casing (4) of the flow path forming member (3). Thereby, the assembling work of the aquarium pipe connector according to this embodiment is completed.
こうして浴槽（Ｔ）に施工された接続具においては、槽外フランジ部材（１）の外管接続部（１２ａ）（１２ｂ）に、室外給湯機からの配管が連結されて、浴槽システムが形成される。 In the connector thus constructed in the bathtub (T), the pipe from the outdoor water heater is connected to the outer pipe connecting portion (12a) (12b) of the tank outer flange member (1) to form a bathtub system. The
この浴槽システムにおいて、浴槽内に温水を供給して貯留する場合には、２つの外管接続部（１２ａ）（１２ｂ）の双方に温水を供給して、２つの流路（Ａ）（Ｂ）が給湯流路として利用される。すなわち第１及び第２外管接続部（１２ａ）（１２ｂ）に供給された温水は、第１及び第２連通パイプ（５ａ）（５ｂ）を通って第１及び第２区画室（３ａ）（３ｂ）に流入される。区画室（３ａ）（３ｂ）に流入された温水は、水圧によって弁部材（９）（９）の吐出弁（９１）（９１）を押し開いて、吐出室（３ｃ）、吐出口（３５）及び吐出用開口（６５）を通って浴槽内に供給される。 In this bathtub system, when hot water is supplied and stored in the bathtub, hot water is supplied to both of the two outer pipe connecting portions (12a) and (12b), and two flow paths (A) and (B) are supplied. Is used as a hot water supply channel. That is, the hot water supplied to the first and second outer pipe connecting portions (12a) and (12b) passes through the first and second communication pipes (5a) and (5b), and the first and second compartments (3a) ( 3b). The warm water that has flowed into the compartments (3a) and (3b) pushes and opens the discharge valves (91) and (91) of the valve members (9) and (9) by water pressure, so that the discharge chamber (3c) and the discharge port (35). And is supplied into the bathtub through the discharge opening (65).
一方、浴槽（Ｔ）内の温水を再加熱するような追い焚き処理を行う場合には、２つの流路（Ａ）（Ｂ）のうち、室外給湯機の往き管に接続された側の流路が給湯側流路として機能し、戻り管に接続された側の流路が吸込側流路として機能して、いわゆる強制循環が行われる。例えば第１流路（Ａ）が給湯側流路、第２流路（Ｂ）が吸込側流路となるように配管接続された場合には、給湯機から供給される温水は、第１流路（Ａ）を通って第１区画室（３ａ）に流入され、第１区画室出口（３１ａ）の吐出弁（９１）を開いて、吐出室（３ｃ）に流入されて、吐出口（３５）及び吐出用開口（６５）を介して浴槽（Ｔ）内に供給される。 On the other hand, in the case of performing a reheating process that reheats the hot water in the bathtub (T), the flow on the side of the two flow paths (A) and (B) that is connected to the forward pipe of the outdoor water heater. The passage functions as a hot water supply side flow path, and the flow path on the side connected to the return pipe functions as a suction side flow path, so-called forced circulation is performed. For example, when the pipes are connected so that the first channel (A) is the hot water supply side channel and the second channel (B) is the suction side channel, the hot water supplied from the water heater is the first flow. It flows into the first compartment (3a) through the passage (A), opens the discharge valve (91) at the outlet (31a) of the first compartment, flows into the discharge chamber (3c), and discharge port (35 ) And the discharge opening (65).
また吸込側流路においては、室外給湯機の戻り管及び第２流路（Ｂ）の負圧に伴い、第２区画室（３ｂ）が負圧となる。このため、浴槽（Ｔ）内の水圧によって、流路形成部材（３）における第２吸込口（３２ｂ）の吸込弁（９２）が開放して、浴槽（Ｔ）内の温水がフィルター部材（６）を介して第２吸込口（３２ｂ）を通って第２区画室（３ｂ）内に流入されて、更に第２流路（Ｂ）を通って室外給湯機に戻される。 Further, in the suction side flow path, the second compartment (3b) becomes negative pressure due to the negative pressure of the return pipe of the outdoor water heater and the second flow path (B). For this reason, the suction valve (92) of the second suction port (32b) in the flow path forming member (3) is opened by the water pressure in the bathtub (T), and the hot water in the bathtub (T) is filtered by the filter member (6). ) Through the second suction port (32b) through the second suction port (32b) and then returned to the outdoor water heater through the second flow path (B).
なお、温水口装置の２の流路（Ａ）（Ｂ）が、室外給湯機の往き管及び戻り管に対し、上記とは逆に接続した場合には、各流路（Ａ）（Ｂ）を温水が上記とは逆方向に流通して、強制循環されるものである。 In addition, when the two flow paths (A) and (B) of the hot water outlet device are connected to the forward pipe and the return pipe of the outdoor water heater in the opposite manner, the flow paths (A) and (B) The hot water is circulated in the direction opposite to the above and forcedly circulated.
以上のように本実施形態の浴槽用配管接続具によれば、槽内フランジ部材（２）に頭部挿通孔（２２）（２２）と、ねじ止め孔（２３）（２３）と、両孔（２２）（２３）間を連通するねじ案内溝（２５）（２５）とを形成するものであるため、連結ねじ（７）（７）の頭部（７２）（７２）を頭部挿通孔（２２）（２２）に挿通し、そのねじ（７）（７）をねじ案内溝（２５）（２５）を介してねじ止め孔（２３）（２３）に案内することにより、槽内フランジ部材（２）をねじ付きの槽外フランジ部材（１）に対し後付け取り付けることができる。このためねじ付きの槽外フランジ部材（１）をその連結ねじ（７）（７）を浴槽孔（Ｈ）に槽外側から挿入して孔周縁部に係止して仮保持しておいて、槽内側から槽内フランジ部材（２）をねじ付き槽外フランジ部材（１）に対し後付けで組み付けることにより、専用の治具等を一切使用せずに、一人作業で簡単に施工することができる。 As mentioned above, according to the pipe connector for bathtubs of this embodiment, the head insertion holes (22) and (22), the screw holes (23) and (23), and both holes are provided in the tank flange member (2). (22) Since the screw guide grooves (25) and (25) communicating with each other are formed, the heads (72) and (72) of the connecting screws (7) and (7) are inserted into the head insertion holes. (22) By inserting the screw (7) and (7) through the screw guide grooves (25) and (25) into the screw holes (23) and (23), the flange member in the tank is inserted. (2) can be retrofitted to the threaded tank outer flange member (1). For this reason, the outer tank flange member (1) with a screw is inserted into the bathtub hole (H) from the outer side of the tank by inserting the connecting screw (7) (7), and is temporarily held by being locked to the peripheral edge of the hole. By assembling the in-tank flange member (2) from the inside of the tank to the threaded tank-outside flange member (1) by retrofitting, it can be easily performed by one person without using any special jigs. .
更に本実施形態においては、槽内フランジ部材８２）に頭部挿通孔（２２）やねじ案内溝（２５）を形成するだけで簡単に作製できるため、構造の簡素化及びコストの削減をより確実に図ることができる。 Furthermore, in this embodiment, since it can be easily manufactured simply by forming the head insertion hole (22) and the screw guide groove (25) in the tank flange member 82), the structure can be simplified and the cost can be reduced more reliably. Can be aimed at.
しかも本実施形態においては、無理なく施工でき、構造の簡素化及びコストの削減を図ることができる。すなわち上記特許文献（特許第３５１３５８２号、特開２０００−５５４７８号）に示す従来の配管接続具のように、槽外に取り付ける部材を浴槽内側から浴槽孔に通してから槽外に取り付けるような構成においては、槽外取付部材を浴槽孔に挿通できるように構成する必要があり、構造の複雑化及びコストの増大を招くとともに、槽外取付部材を浴槽孔に挿通する等、面倒な操作も必要となり、施工作業がより一層困難になってしまう。 And in this embodiment, it can construct without difficulty and can aim at simplification of a structure and reduction of cost. That is, the structure which attaches the member attached outside the tank through the bathtub hole from the inside of the bathtub and then outside the tank as in the conventional pipe connector shown in the above-mentioned patent documents (Japanese Patent Nos. 3513582 and 2000-55478) In this case, it is necessary to configure the tank outer mounting member so that it can be inserted into the bathtub hole, which increases the complexity of the structure and the cost, and also requires troublesome operations such as inserting the tank outer mounting member into the bathtub hole. Thus, the construction work becomes even more difficult.
これに対し、本実施形態においては、槽外フランジ部材（１）等の槽外に取り付ける部材は槽外から施工するとともに、槽内フランジ部材（２）等の槽内に取り付ける部材は槽内から施工するものであるため、無理なく簡単に施工できるとともに、構造の簡素化及びコストの削減を図ることができる。 On the other hand, in this embodiment, while attaching the member attached outside a tank, such as a tank outer flange member (1), from the tank outside, the member attached inside a tank, such as a tank flange member (2), is from inside the tank. Since it is to be constructed, it can be constructed easily and without difficulty, and the structure can be simplified and the cost can be reduced.
また本実施形態では、２本の連結ねじ（７）（７）により槽内フランジ部材（２）を槽外フランジ部材（１）にねじ止め固定するものであるため、両フランジ部材（１）（２）をバランス良く安定した状態に固定することができる。更にねじ付き槽外フランジ部材（１）を浴槽孔に仮保持する際にも、２本の連結ねじ（７）（７）によって安定状態に保持させることができ、槽外フランジ部材（１）の脱外等の不具合をより確実に防止することができる。 Moreover, in this embodiment, since the tank inner flange member (2) is screwed and fixed to the tank outer flange member (1) with two connecting screws (7) (7), both flange members (1) ( 2) can be fixed in a balanced and stable state. Further, when the threaded tank outer flange member (1) is temporarily held in the bathtub hole, it can be held in a stable state by the two connecting screws (7) and (7). Problems such as detachment can be prevented more reliably.
また本実施形態においては、頭部挿通孔（２２）とねじ止め孔（２３）とを槽内フランジ部材（２）の中心位置から等距離に設けるとともに、両孔（２２）（２３）間を連通するねじ案内溝（２５）を槽内フランジ部材（２）の中心位置を中心とする円弧線に沿って円弧状に形成するものであるため、頭部挿通孔（２２）にねじ頭部（７２）を挿通した後、槽内フランジ部材（２）を槽外フランジ部材（１）に対し相対的に軸心回りに回転操作するだけで簡単に、ねじ（７）をねじ案内溝（２５）に沿ってねじ止め孔（２３）まで案内することができ、施工作業をスムーズに行うことができる。 Further, in the present embodiment, the head insertion hole (22) and the screwing hole (23) are provided at an equal distance from the center position of the tank flange member (2), and between the holes (22) and (23). Since the screw guide groove (25) that communicates is formed in an arc shape along an arc line centered on the center position of the tank flange member (2), the screw head ( 72), after inserting the tank inner flange member (2) relative to the tank outer flange member (1), the screw (7) can be simply screwed into the screw guide groove (25). Can be guided to the screw hole (23) along the line, and the construction work can be performed smoothly.
更に槽内フランジ部材（２）におけるねじ案内溝（２５）の途中に戻り防止用突起部（２５ａ）を形成しているため、ねじ止め孔（２３）に配置したねじ（７）は、突起部（２５ａ）に当接係止することにより、ねじ案内溝（２５）に沿って逆戻りするのを防止することができる。このようにねじ（７）がねじ止め孔（２３）から位置ずれするのを防止でき、施工作業をより一層スムーズに行うことができる。 Further, since the protrusion (25a) for preventing return is formed in the middle of the screw guide groove (25) in the tank flange member (2), the screw (7) disposed in the screwing hole (23) By abutting and locking on (25a), it is possible to prevent the reverse movement along the screw guide groove (25). As described above, the screw (7) can be prevented from being displaced from the screw hole (23), and the construction work can be performed more smoothly.
また本実施形態においては、流路形成部材（３）の連通パイプ（５ａ）（５ｂ）を槽内フランジ部材（２）の頭部挿通孔（２２）（２２）に通して、槽外フランジ部材（１）の外管接続部（１２ａ）（１２ｂ）に連通接続するものであるため、槽内フランジ部材（２）に連通パイプ挿通用の孔等を別途設ける必要がなく、その分、構造の簡素化を図ることができる。 Moreover, in this embodiment, the communicating pipe (5a) (5b) of the flow path forming member (3) is passed through the head insertion holes (22) (22) of the in-tank flange member (2), and the tank-outside flange member Since it is connected in communication with the outer pipe connection parts (12a) and (12b) of (1), there is no need to separately provide a hole or the like for insertion of a communication pipe in the tank flange member (2). Simplification can be achieved.
図９及び図１０はこの発明の他の実施形態である浴槽用配管接続具に用いられた槽外フランジ部材（１）を示す図である。両図に示すようにこの接続具に用いられる槽外フランジ部材（１）は、縦横のうち一方側の寸法が浴槽孔（Ｈ）の直径よりも小さく、かつ他方側の寸法が浴槽孔（Ｈ）よりも大きい細長形状の基板（１１）を有している。そしてこの槽外フランジ部材（１）は、長さ方向の両端部（１１ａ）（１１ａ）を浴槽孔（Ｈ）の槽外側周縁部に圧接させるとともに、槽内フランジ部材（２）の外周縁部を浴槽孔（Ｈ）の槽内側周縁部に圧接させるように、連結ねじ（７）（７）を槽内フランジ部材（２）側から槽外フランジ部材（１）に締め付け固定するものである。その他の構成は上記実施形態と同様である。 FIG.9 and FIG.10 is a figure which shows the tank outer flange member (1) used for the piping connector for bathtubs which is other embodiment of this invention. As shown in both figures, the tank outer flange member (1) used in this connector has a vertical and horizontal dimension on one side smaller than the diameter of the bathtub hole (H) and the other dimension on the bathtub hole (H The substrate (11) has an elongated shape larger than (). And this tank outer flange member (1) presses the both ends (11a) (11a) of a length direction on the tank outer periphery part of a bathtub hole (H), and the outer periphery part of a tank inner flange member (2) The connection screws (7) and (7) are fastened and fixed from the tank inner flange member (2) side to the tank outer flange member (1) so as to be brought into pressure contact with the inner peripheral edge of the bathtub hole (H). Other configurations are the same as those in the above embodiment.
この実施形態の配管接続具においては、槽外フランジ部材（１）の基板（１１）を浴槽孔（Ｈ）に挿通することができるため、施工時に、図１１に示すように基板（１１）を浴槽孔（１１）に係止しておけば、連結ねじ（７）（７）の軸部（７３）（７３）を浴槽孔（１１）に係止するだけで、槽外フランジ部材（１）を仮保持することができる。つまり仮保持状態において、連結ねじ（７）（７）の頭部（７２）（７２）を浴槽内部に大きく引き出して配置することができる。このため、浴槽内側から連結ねじ（７）（７）を槽内フランジ部材（２）の頭部挿通孔（２２）等への挿入作業を容易に行うことができ、施工作業をより一層スムーズに行うことができる。 In the pipe connector of this embodiment, since the substrate (11) of the tank outer flange member (1) can be inserted into the bathtub hole (H), the substrate (11) is attached as shown in FIG. If it is locked in the bathtub hole (11), the tank outer flange member (1) can be obtained simply by locking the shaft portions (73) and (73) of the connecting screws (7) and (7) in the bathtub hole (11). Can be temporarily held. That is, in the temporary holding state, the heads (72) and (72) of the connecting screws (7) and (7) can be largely pulled out and arranged inside the bathtub. For this reason, it is possible to easily insert the connection screws (7) and (7) into the head insertion hole (22) of the in-tank flange member (2) from the inside of the bathtub, making the construction work even smoother. It can be carried out.
なおこの実施形態のように、槽外フランジ部材（１）を浴槽孔（Ｈ）に係止させるためには、槽外フランジ部材（１）の少なくとも一部を、浴槽孔（Ｈ）に挿入できるような構成を採用すれば良い。 In addition, in order to lock the tank outer flange member (1) to the bathtub hole (H) as in this embodiment, at least a part of the tank outer flange member (1) can be inserted into the bathtub hole (H). Such a configuration may be adopted.
ところで上記他の実施形態のように、槽外フランジ部材（１）の基板（１１）を浴槽孔（Ｈ）に挿通できるように形成すると、浴槽孔（Ｈ）の一部が浴槽外側に開放されることになるが、槽内フランジ部材（２）における基板（１１）の前後両面に第１及び第２パッキン（８１）（８２）を装着しているため、浴槽内と浴槽孔（Ｈ）内部との間の水密、ひいては浴槽内と浴槽外部との水密を確実に図ることができる。 By the way, if it forms so that the board | substrate (11) of a tank outer flange member (1) can be inserted in a bathtub hole (H) like said other embodiment, a part of bathtub hole (H) will be open | released outside the bathtub. However, since the first and second packings (81) and (82) are attached to the front and rear surfaces of the substrate (11) in the tank flange member (2), the inside of the bathtub and the inside of the bathtub hole (H) Water tightness between the two, and consequently water tightness between the inside of the bathtub and the outside of the bathtub can be ensured.
図１２はこの発明の第１変形例としての浴槽用配管接続具におけるパッキン部材付き槽内フランジ部材（２）を示す図である。この槽内フランジ部材（２）の外周縁部に沿ってパッキン部材（８０）が取り付けられている。すなわち環状パッキン部材（８０）は、連続する内周溝（８５）が設けられたコ字型断面の形状を有しており、このパッキン部材（８）が、その内周溝（８５）内に槽内フランジ部材（２）における基板（２１）の外周縁部を嵌め込むようにして配置される。そしてこのパッキン部材（８０）の一側壁部、つまり槽内フランジ部材（２）の後面側外周に配置される部分が、槽内フランジ部材（２）及び浴槽壁間の水密を図るための第１パッキン（８１）として構成されるとともに、パッキン部材（８０）の他側壁部、つまり槽内フランジ部材（２）の前面側外周に配置される部分が、槽内フランジ部材（２）及び流路形成部材（３）間の水密を図るための第２パッキン（８２）として構成される。 FIG. 12: is a figure which shows the flange member (2) in a tank with a packing member in the piping connector for bathtubs as a 1st modification of this invention. A packing member (80) is attached along the outer peripheral edge of the tank flange member (2). That is, the annular packing member (80) has a U-shaped cross-sectional shape provided with a continuous inner circumferential groove (85), and the packing member (8) is placed in the inner circumferential groove (85). It arrange | positions so that the outer periphery part of the board | substrate (21) in a tank flange member (2) may be inserted. And the one side wall part of this packing member (80), ie, the part arrange | positioned in the rear surface side outer periphery of the tank inner flange member (2), is the 1st for aiming at watertightness between the tank inner flange member (2) and the bathtub wall. The other side wall portion of the packing member (80), that is, the portion disposed on the outer periphery on the front side of the tank flange member (2) is formed as the packing flange (81) and the flow path formation in the tank flange member (2). It is comprised as the 2nd packing (82) for aiming at watertightness between members (3).
この第１変形例においては、第１及び第２パッキン（８１）（８２）が一体化されたパッキン部材（８０）を用いるものであるため、パッキン部材（８０）を装着するだけで、第１及び第２の２つのパッキン（８１）（８２）を装着することができ、部品点数の削減を図ることができ、施工作業をより一層簡単に行うことができる。 In the first modified example, since the packing member (80) in which the first and second packings (81) and (82) are integrated is used, the first member is simply attached to the packing member (80). In addition, the second two packings (81) and (82) can be mounted, the number of parts can be reduced, and the construction work can be performed more easily.
なお上記実施形態においては、連結ねじ（７）を２本採用する場合を例に挙げて説明したが、それだけに限られず、本発明においては、１本又は３本以上の連結ねじによって槽内フランジ部材を槽外フランジ部材にねじ止めするように構成しても良い。 In the above embodiment, the case where two connecting screws (7) are employed has been described as an example. However, the present invention is not limited to this. In the present invention, one or three or more connecting screws are used for the flange member in the tank. May be configured to be screwed to the tank outer flange member.
例えば図１３に示すように、槽外フランジ部材（１）における基板（１１）の片側にねじ（７）を取り付けて、そのねじ付き槽外フランジ部材（１）を用いて、上記と同様に浴槽（Ｔ）に施工するようにしても良い。このねじ付き槽外フランジ部材（１）においては、施工時に、１本のねじ（７）を浴槽孔（Ｈ）に引っ掛けるようにして、浴槽外面に仮保持するものであるが、その後、槽内フランジ部材（２）を締め付ける際には、ねじ（７）を１本付け加えて、計２本のねじ（７）で槽内フランジ部材（２）を槽外フランジ部材（１）に締め付け固定するようにしても良いし、１本のねじ（７）のままで槽内フランジ部材（２）を槽外フランジ部材（１）に締め付け固定するようにしても良い。 For example, as shown in FIG. 13, a screw (7) is attached to one side of the substrate (11) in the tank outer flange member (1), and the bathtub outer flange member (1) is used in the same manner as described above. You may make it construct to (T). In this threaded tank outer flange member (1), at the time of construction, one screw (7) is hooked in the bathtub hole (H) and temporarily held on the outer surface of the bathtub. When tightening the flange member (2), add one screw (7) and tighten and fix the tank flange member (2) to the tank flange member (1) with a total of two screws (7). Alternatively, the tank inner flange member (2) may be fastened and fixed to the tank outer flange member (1) with one screw (7).
また上記実施形態においては、本発明を無極性タイプの配管接続具に適用した場合を例に挙げて説明したが、本発明は、給湯機につながる往き管及び戻り管が予め設定されている配管接続具にも適用することができる。 Moreover, in the said embodiment, although the case where this invention was applied to the nonpolar type piping connection tool was mentioned as an example and demonstrated, this invention is piping in which the outgoing pipe and return pipe connected to a water heater are preset. It can also be applied to connectors.
更に上記実施形態においては、強制循環タイプの追い焚き可能な装置を例に挙げて説明したが、本発明は、湯はり等の貯湯処理のみを行う配管接続具にも適用することができる。 Further, in the above-described embodiment, the forced circulation type replenishable device has been described as an example. However, the present invention can also be applied to a pipe connector that performs only hot water storage processing such as hot water.
更に本発明は、温水を浴槽内に供給するだけの１本の流路（シングル配管）を有する配管接続具にも適用することができる。この場合例えば図１４に示すように、槽外フランジ部材（１）としては、基板（１１）に外管接続部（１２）が一つだけ設けられたものを用いれば良い。 Furthermore, this invention is applicable also to the piping connector which has one flow path (single piping) which only supplies warm water in a bathtub. In this case, for example, as shown in FIG. 14, as the tank outer flange member (1), a substrate (11) provided with only one outer pipe connecting portion (12) may be used.
この発明の浴槽用配管接続具は、室外給湯機から浴槽内にお湯を供給するに際して、浴槽壁面に設けられる温水アダプター等の温水口装置として利用可能である。 The bathtub pipe connector according to the present invention can be used as a hot water outlet device such as a hot water adapter provided on the bathtub wall surface when hot water is supplied into the bathtub from the outdoor water heater.
