Description

この発明は、水栓本体内に軸線方向に移動可能に設けられた可動弁体を、形状記憶材料よりなる感温バネとバイアスバネとにより軸線方向の両側から付勢するように構成されている湯水混合栓に関するものである。   The present invention is configured to urge a movable valve body provided in a faucet body so as to be movable in the axial direction from both sides in the axial direction by a temperature-sensitive spring and a bias spring made of a shape memory material. It relates to hot and cold mixing taps.

図５は、後述する筒状ハウジング（サーモカートリッジ）に内蔵されている形状記憶材料よりなる感温バネによって温度調整を行うよう構成された、この種の湯水混合栓の要部を示している。図５において、湯水混合栓は、水栓本体（図示せず）内に設けられた水側弁座３１及び湯側弁座２６と、これら両弁座３１，２６に選択的に接離するように水栓本体内に同軸上で軸線方向に移動可能に設けられた可動弁体２２と、この可動弁体２２の上流側及び下流側の水栓本体内にそれぞれ形成された湯流入室Ｓ及び湯水混合室Ｒと、前記可動弁体２２を湯側弁座２６と接近する方向に付勢するように前記湯水混合室Ｒ側に設けられた形状記憶材料よりなる感温バネ２７と、この感温バネ２７の付勢力に対向させて前記可動弁体２２を水側弁座３１と接近する方向に付勢するように前記湯流入室Ｓ側に設けられたバイアスバネ３２と、水栓本体の一端に設けられ前記可動弁体２２を軸線方向に移動可能に収容するとともに、前記感温バネ２７及びバイアスバネ３２を内蔵する筒状ハウジング（サーモカートリッジ）２１と、この筒状ハウジング２１内に収容され温度調整用ハンドル（図示せず）の回転操作に連動して回転する温度調整用栓棒２８と、この温度調整用栓棒２８の先端側に形成された雄ねじ部３０に螺合する雌ねじ部３４を有し前記温度調整用栓棒２８の回転に伴い筒状ハウジング２１内を軸線方向に移動する筒状の移動部材２９とを備え、この移動部材２９の軸線方向移動により前記バイアスバネ３２を伸縮させて前記可動弁体２２を軸線方向に移動させることによって湯水混合水の吐水温度を調整可能に構成されている。なお、１１３で示す点線矢印は、湯配管から水栓本体に流入し、可動弁体２２と湯側弁座２６との隙間を通り湯流入室Ｓから可動弁体２２に形成された中央孔を通って湯水混合室Ｒに至る湯流入路を示す。なお、２０は、水栓本体との間に水の環状流路（図示せず）を形成する筒状の外ケースである。２４ａ，２８ａは、温度調整用栓棒２８と筒状ハウジング（サーモカートリッジ）２１における固定ガイド部材２４の環状壁面との接触面で、テーパー面に形成されている。３５は、前記両テーパー面２４ａ，２８ａに連なる温度調整用栓棒２８の外周面と筒状ハウジング（サーモカートリッジ）２１の内周面との間に介在されている水密用シールリングである。   FIG. 5 shows a main part of this kind of hot and cold water mixing tap configured to adjust the temperature by a temperature-sensitive spring made of a shape memory material incorporated in a cylindrical housing (thermo cartridge) described later. In FIG. 5, the hot and cold water mixing tap is selectively brought into and out of contact with the water side valve seat 31 and the hot water side valve seat 26 provided in the faucet body (not shown). A movable valve body 22 provided coaxially within the faucet body so as to be movable in the axial direction, and hot water inflow chambers S formed in the faucet bodies upstream and downstream of the movable valve body 22 respectively. A hot water mixing chamber R, a temperature sensitive spring 27 made of a shape memory material provided on the hot water mixing chamber R side so as to urge the movable valve body 22 in a direction approaching the hot water valve seat 26, and this feeling A bias spring 32 provided on the hot water inflow chamber S side so as to urge the movable valve body 22 in a direction approaching the water side valve seat 31 in opposition to the urging force of the temperature spring 27, and a faucet body The movable valve body 22 is provided at one end so as to be movable in the axial direction, and the temperature-sensitive spring 2 And a cylindrical housing (thermo cartridge) 21 containing a bias spring 32, and a temperature adjusting plug rod 28 which is housed in the cylindrical housing 21 and rotates in conjunction with a rotating operation of a temperature adjusting handle (not shown). And an internal thread portion 34 that is screwed into an external thread portion 30 formed on the distal end side of the temperature adjusting plug rod 28 and moves in the cylindrical housing 21 in the axial direction as the temperature adjusting plug rod 28 rotates. A cylindrical moving member 29 that can be adjusted, and the biasing spring 32 is expanded and contracted by moving the moving member 29 in the axial direction to move the movable valve body 22 in the axial direction to adjust the discharge temperature of the hot and cold mixed water. It is configured. A dotted line arrow 113 indicates that a central hole formed in the movable valve body 22 from the hot water inflow chamber S passes through the gap between the movable valve body 22 and the hot water side valve seat 26 from the hot water pipe into the faucet body. The hot water inflow path which leads to the hot water mixing chamber R is shown. Reference numeral 20 denotes a cylindrical outer case that forms an annular channel (not shown) of water between the faucet body. Reference numerals 24 a and 28 a denote contact surfaces between the temperature adjusting plug rod 28 and the annular wall surface of the fixed guide member 24 in the cylindrical housing (thermo cartridge) 21, and are formed into tapered surfaces. Reference numeral 35 denotes a watertight seal ring interposed between the outer peripheral surface of the temperature adjusting plug rod 28 connected to both the tapered surfaces 24 a and 28 a and the inner peripheral surface of the cylindrical housing (thermo cartridge) 21.

ところで、この種の湯水混合栓では、前記筒状ハウジング（サーモカートリッジ）２１に内蔵されている形状記憶材料よりなる感温バネ２７によって温度調整を行う構造となっているが、温度調整用ハンドル（温度調整用栓棒２８）を高温方向に操作すると、バネの反発力が加わり、その反発力が温度調整用ハンドル（温度調整用栓棒２８）の回転（自転）を発生させており、高温をキープすることが難しい。   By the way, this kind of hot and cold water mixing tap has a structure in which the temperature is adjusted by a temperature-sensitive spring 27 made of a shape memory material incorporated in the cylindrical housing (thermo cartridge) 21. When the temperature adjusting plug rod 28) is operated in a high temperature direction, a spring repulsive force is applied, and the repulsive force causes rotation (spinning) of the temperature adjusting handle (temperature adjusting plug rod 28). It is difficult to keep.

すなわち、可動弁体２２が高温の吐水域に位置された状態において、感温バネ２７が大きく圧縮されて感温バネ２７の付勢力が著しく増大されることになり、この感温バネ２７の付勢力とバイアスバネ３２の蓄力とが総和して筒状ハウジング（サーモカートリッジ）内の移動部材２９に強大な軸力が働き、この強大な軸力によって移動部材２９に雌ねじ部３４及び雄ねじ部３０を介して螺合連係されている温度調整用栓棒２８に回転力が作用して温度調整用栓棒２８が不測に自転されることになる。そして、温度調整用栓棒２８の自転により、可動弁体２２が水側弁座３１から離間する方向に移動され、その結果、冷水が湯水混合室Ｒに流入して、高温吐水域に調整（設定）された吐水温度を維持できないという不良事態を招きやすい。   That is, in the state where the movable valve body 22 is positioned in the high temperature water discharge region, the temperature sensitive spring 27 is greatly compressed and the urging force of the temperature sensitive spring 27 is remarkably increased. The force and the accumulated force of the bias spring 32 are summed up to cause a strong axial force to act on the moving member 29 in the cylindrical housing (thermo cartridge), and this strong axial force causes the female screw portion 34 and the male screw portion 30 to act on the moving member 29. Rotational force acts on the temperature adjusting plug rod 28 that is screwed together via this, and the temperature adjusting plug rod 28 rotates unexpectedly. Then, the movable valve element 22 is moved away from the water side valve seat 31 by the rotation of the temperature adjusting plug rod 28. As a result, cold water flows into the hot water mixing chamber R and is adjusted to a high temperature water discharge area ( It is easy to cause a failure that the set water discharge temperature cannot be maintained.

そこで、温度調整用ハンドル（温度調整用栓棒２８）の自転を防止する手段として、図６に示すように、筒状ハウジング（サーモカートリッジ）２１の一端側開口部２１ａに同軸上に外嵌（例えばローレット結合）されるラチェットギア４０を設ける一方、このラチェットギア４０の外面に形成された波状の突起４０ａに噛合するツメ４１が形成された二箇所のツメ部Ａ，Ｂを有するラチェットリング４２（図６、図７参照）を設けること（比較例）が考えられる。このラチェットリング４２は、温度調整用栓棒２８と連動して回転するよう構成され、ラチェットリング４２の円周部（環状部）ａに形成された二つの切欠き４３を介して、正面視Ｃ型に形成した抵抗面（ツメ４１）を有するツメ部４２ａ（以下、Ｃ型部分という）と、短円弧状に形成した抵抗面のない部分４２ｂを備える。すなわち、Ｃ型部分４２ａの円周部分（環状部分）ａの内周面における二箇所Ａ，Ｂに前記ツメ４１が形成される。そして、温度調整用ハンドル（温度調整用栓棒２８）を回動操作させると、前記ツメ４１でラチェットギア４０を掴んだ状態で、Ｃ型部分４２ａは、その弾性により内外方向に変形しながら温度調整用ハンドルの回転に抵抗を与える。   Therefore, as means for preventing the rotation of the temperature adjustment handle (temperature adjustment plug rod 28), as shown in FIG. 6, it is fitted on the one end side opening 21a of the cylindrical housing (thermo cartridge) 21 coaxially ( For example, a ratchet gear 42 (for example, knurled) is provided, and a ratchet ring 42 having two claw portions A and B each having a claw 41 that meshes with a wave-like protrusion 40 a formed on the outer surface of the ratchet gear 40 ( It is conceivable to provide (see FIGS. 6 and 7). The ratchet ring 42 is configured to rotate in conjunction with the temperature adjusting plug rod 28, and is viewed through the two notches 43 formed in the circumferential portion (annular portion) a of the ratchet ring 42. A claw portion 42a (hereinafter referred to as a C-shaped portion) having a resistance surface (claw 41) formed in a mold and a portion 42b having no resistance surface formed in a short arc shape are provided. That is, the claw 41 is formed at two locations A and B on the inner peripheral surface of the circumferential portion (annular portion) a of the C-shaped portion 42a. When the temperature adjustment handle (temperature adjustment plug bar 28) is turned, the C-shaped portion 42a is deformed inward and outward due to its elasticity while the ratchet gear 40 is gripped by the claw 41. Resist the rotation of the adjustment handle.

しかしながら、二箇所Ａ，Ｂのツメ４１でラチェットギア４０を掴む（Ｃ型部分４２ａだけでラチェットギア４０を掴む）ようなＣ型の掴み方では、片側がフリーになってしまうため（片方の部分４２ｂにはラチェットギア４０を掴むツメがないため）、ギア４０の掴み（ラチェットギア４０の掛り）が不十分となり、前記自転の抑制が不充分であるおそれがある。すなわち、ギア４０の掛りよりも感温バネ２７の反発力が上回り、前記自転が発生してしまうおそれがある。また、ラチェットリング４２のＣ型部分４２ａの円周部分（環状部分）ａは肉厚であることから、ギア４０が乗り上げた後の反動が大きく、そのため温度調整用ハンドルの回転操作における「カチカチ」という操作音が大きい。   However, in a C-shaped gripping method in which the ratchet gear 40 is gripped by the claws 41 of the two locations A and B (the ratchet gear 40 is gripped only by the C-shaped portion 42a), one side becomes free (one portion) 42b does not have a claw for gripping the ratchet gear 40), the gripping of the gear 40 (hanging of the ratchet gear 40) becomes insufficient, and there is a possibility that the suppression of the rotation is insufficient. That is, the repulsive force of the temperature-sensitive spring 27 exceeds the hook of the gear 40, and the rotation may occur. Further, since the circumferential portion (annular portion) a of the C-shaped portion 42a of the ratchet ring 42 is thick, the reaction after the gear 40 rides on is large, and therefore “tick” in the rotation operation of the temperature adjustment handle. The operation sound is loud.

この発明の目的は、ラチェットギアを掴む力を強くできる（ラチェットギアの掛りを強くできる）とともに、温度調整用栓棒が不測に自転される事態を回避することができ、さらには温度調整用ハンドルの回転操作における操作音を緩和することができる湯水混合栓を提供することである。   The object of the present invention is to increase the force of gripping the ratchet gear (to increase the latching of the ratchet gear), to avoid a situation in which the temperature adjusting plug rod rotates unexpectedly, and further to the temperature adjusting handle. It is an object to provide a hot and cold water mixing tap that can alleviate the operation sound in the rotation operation of the water.

上記目的を達成するために、この発明は、水栓本体の一端に設けられ可動弁体を軸線方向に移動可能に収容するとともに、感温バネ及びバイアスバネを内蔵する筒状ハウジングと、
この筒状ハウジング内に収容され温度調整用ハンドルの回転操作に連動して回転する温度調整用栓棒と、
この温度調整用栓棒に形成された雄ねじ部に螺合する雌ねじ部を有し前記温度調整用栓棒の回転に伴い筒状ハウジング内を軸線方向に移動する筒状の移動部材とを備え、
この移動部材の軸線方向移動により前記バイアスバネを伸縮させて前記可動弁体を軸線方向に移動させることによって湯水混合水の吐水温度を調整可能に構成している湯水混合栓において、
外面に波状の突起が形成されたラチェットギアを設け、このラチェットギアが前記筒状ハウジングの一端側開口部に同軸上に外嵌される一方、このラチェットギアを掴むツメを有するツメ部が円周部の内周面に形成されたラチェットリングを設けるとともに、このラチェットリングは前記温度調整用栓棒と連動して回転するよう構成されており、
さらに、前記ラチェットリングには、少なくとも三箇所の前記ツメ部が前記円周部の全周にわたり所定間隔で設けられていることを特徴としている（請求項１）。 In order to achieve the above object, the present invention includes a cylindrical housing that is provided at one end of a faucet body and that accommodates a movable valve body so as to be movable in the axial direction, and that includes a temperature-sensitive spring and a bias spring.
A temperature adjusting plug rod which is housed in the cylindrical housing and rotates in conjunction with the rotation operation of the temperature adjusting handle;
A cylindrical moving member that has a female screw portion that is screwed into a male screw portion that is formed on the temperature adjusting plug rod, and moves in the axial direction in the cylindrical housing as the temperature adjusting plug rod rotates,
In the hot and cold water mixing tap configured to adjust the water discharge temperature of the hot and cold water mixture by moving the movable valve body in the axial direction by expanding and contracting the bias spring by the axial movement of the moving member,
A ratchet gear having a wave-like projection formed on the outer surface is provided, and the ratchet gear is coaxially fitted to the opening on one end side of the cylindrical housing, while a claw portion having a claw for gripping the ratchet gear is circumferential. Provided with a ratchet ring formed on the inner peripheral surface of the part, the ratchet ring is configured to rotate in conjunction with the temperature adjustment plug rod,
Further, the ratchet ring is characterized in that at least three claw portions are provided at predetermined intervals over the entire circumference of the circumferential portion (Claim 1).

また、この発明では、前記ラチェットリングの前記円周部の外周面には、所定間隔を有して複数の凹みが形成されており、それらの凹みの直下に前記ツメ部が設けられている一方、前記ラチェットリングの前記円周部の内周面と前記ラチェットギアの外面との間に空間が形成されているのが好ましい（請求項２）。   In the present invention, the outer peripheral surface of the circumferential portion of the ratchet ring is formed with a plurality of recesses with a predetermined interval, and the claw portion is provided directly below the recesses. Preferably, a space is formed between the inner peripheral surface of the circumferential portion of the ratchet ring and the outer surface of the ratchet gear (claim 2).

請求項１に記載された発明では、外面に波状の突起が形成されたラチェットギアが前記筒状ハウジングの一端側開口部に同軸上に外嵌される一方、ラチェットギアを掴むツメを有するツメ部が円周部の内周面に形成されているラチェットリングを設け、このラチェットリングを温度調整用栓棒と連動して回転するよう構成し、前記ツメ部を少なくとも三箇所、前記円周部の全周にわたり所定間隔で設けることにより、ラチェットギアを掴む掴み方が片側からのみのため（Ｃ型の掴み方のため）ツメによるラチェットギアの掴みが不十分である（ラチェットギアの掛りが弱い）ものに比べて、前記ツメ部によるラチェットギアの掴みを両側からにできる（Ｏ型の掴み方にして全周的にラチェットギアを掴むことができてラチェットギアの掛りを強くできる）ようにし、それによって、形状記憶材料よりなる感温バネの反発による温度調整用ハンドル（温度調整用栓棒）の回転（自転）を効果的に抑制することができる。   In the first aspect of the present invention, the ratchet gear having a wave-like projection formed on the outer surface is coaxially fitted to the one end side opening of the cylindrical housing, and has a claw having a claw for gripping the ratchet gear. Is provided with a ratchet ring formed on the inner peripheral surface of the circumferential portion, and the ratchet ring is configured to rotate in conjunction with the temperature adjusting plug rod. Providing the ratchet gear at a predetermined interval over the entire circumference allows the ratchet gear to be gripped only from one side (because of the C-type grip), and the ratchet gear is not sufficiently gripped by the claws (the ratchet gear is weakly hooked) The ratchet gear can be gripped by the claw part from both sides compared to the one (the O-type grip can be used to grip the ratchet gear all around, and the ratchet gear can be hooked. Kudekiru) As to it, it is possible to effectively suppress the rotation of the temperature adjustment handle by repulsion of the temperature sensing spring made of a shape memory material (temperature adjusting stopper rod) and (rotation).

さらに、前記ツメ部の箇所の数を適宜の数に増やすことにより、温度調整用ハンドル（温度調整用栓棒）の回転（自転）の抑制力を向上させることができる。   Further, by increasing the number of the claw portions to an appropriate number, it is possible to improve the suppression force of rotation (rotation) of the temperature adjustment handle (temperature adjustment plug bar).

請求項２に記載された発明では、ラチェットリングの円周部の厚みをＣ型のものよりも薄くでき、温度調整用ハンドルの回転操作時の柔軟性が生まれ、温度調整用ハンドルの回転操作における「カチカチ」という操作音の軽減が可能である。   In the invention described in claim 2, the thickness of the circumferential portion of the ratchet ring can be made thinner than that of the C-type, and flexibility at the time of rotating the temperature adjusting handle is born. The operation sound “tick” can be reduced.

Pass through to the hot water mixing chamber R.

以下、特徴的構成について説明する。   Hereinafter, a characteristic configuration will be described.

図１〜図４において、１は、外面に波状の突起１ａ，１ａ，…が形成されたラチェットギアである。ラチェットギア１は、筒状ハウジング（サーモカートリッジ）２１の固定ガイド部材２４に形成されている一端側開口部２４ａに同軸上に外嵌（例えばローレット結合）されている。２は、ラチェットリングである。ラチェットリング２には、ラチェットギア１の外面に形成された波状の突起１ａに噛合するツメ３が形成されている。すなわち、ラチェットリング２は、前記突起１ａを介してラチェットギア１を掴むツメ３を有するツメ部Ｅ，Ｆ，Ｇ，Ｈが円周部（環状部）４の内周面ｍに形成されている。   1 to 4, reference numeral 1 denotes a ratchet gear in which wavy projections 1a, 1a,... Are formed on the outer surface. The ratchet gear 1 is coaxially fitted (for example, knurled) to one end side opening 24 a formed in the fixed guide member 24 of the cylindrical housing (thermo cartridge) 21. 2 is a ratchet ring. The ratchet ring 2 is formed with a claw 3 that meshes with a wave-like protrusion 1 a formed on the outer surface of the ratchet gear 1. That is, the ratchet ring 2 is formed on the inner peripheral surface m of the circumferential portion (annular portion) 4 with claw portions E, F, G, and H having a claw 3 that grips the ratchet gear 1 via the protrusion 1a. .

そして、ラチェットリング２は前記温度調整用栓棒２８と連動して回転するよう構成されている。すなわち、ラチェットリング２は、ラチェットリング２の取付用中央穴５を介して前記栓棒２８の大径壁面部６に挿嵌・固定されている。その際、ラチェットリング２は、円周部（環状部）４の一方端面ｎが固定ガイド部材２４の大径外周端面７に当接した状態で、前記栓棒２８に、抜け止め用のＣリング８が円周部（環状部）４の他方端面ｎ’に当接するまで嵌込まれている。   The ratchet ring 2 is configured to rotate in conjunction with the temperature adjusting plug rod 28. That is, the ratchet ring 2 is inserted and fixed to the large-diameter wall surface portion 6 of the plug bar 28 via the mounting center hole 5 of the ratchet ring 2. At that time, the ratchet ring 2 is attached to the stopper rod 28 with a C ring for preventing the ratchet ring 2 in a state where one end surface n of the circumferential portion (annular portion) 4 is in contact with the large-diameter outer peripheral end surface 7 of the fixed guide member 24. 8 is fitted until it contacts the other end surface n ′ of the circumferential portion (annular portion) 4.

さらに、ラチェットリング２には、四箇所の前記ツメ部Ｅ，Ｆ，Ｇ，Ｈが前記円周部４の全周にわたり所定間隔で設けられている。すなわち、図７で上述した比較例とは異なり、ツメ３（ツメ部Ｅ，Ｆ，Ｇ，Ｈ）でラチェットギア１を掴む掴み方をＯ型（ツメ３を４箇所）に増やすことで、すなわち、４箇所のツメ部Ｅ，Ｆ，Ｇ，Ｈを、円周部４の全周にわたり所定間隔で設けることで、全周的に掴む場所が増える。なお、たとえ比較例のＣ型部分４２ａに４箇所のツメ部を設けても、比較例のＣ型部分４２ａは全周的に掴む構成ではないが、この実施形態では全周的に掴むので比較例に比べてツメ３の掛りを強めることができる。さらに、ツメ部Ｅ，Ｆ，Ｇ，Ｈの数を四つ以上とすることで自転の抑制力を向上できる。   Further, the ratchet ring 2 is provided with four claw portions E, F, G, H at predetermined intervals over the entire circumference of the circumferential portion 4. That is, unlike the comparative example described above with reference to FIG. 7, the number of grips for gripping the ratchet gear 1 with the claws 3 (claw portions E, F, G, and H) is increased to the O type (four claws 3). By providing the four claw portions E, F, G, and H at predetermined intervals over the entire circumference of the circumferential portion 4, the number of places to be gripped over the entire circumference increases. Even if four claw portions are provided in the C-shaped portion 42a of the comparative example, the C-shaped portion 42a of the comparative example is not configured to be gripped all around, but in this embodiment, it is gripped all around. The hook of the tab 3 can be strengthened compared to the example. Furthermore, the suppression force of rotation can be improved by making the number of claw parts E, F, G, and H four or more.

さらに、この実施形態では、前記ラチェットリング２の前記円周部４の外周面４ａには、適宜の所定間隔を有して複数の凹み１０（この実施形態では四つの凹み）が形成されており、それらの凹み１０の直下にそれぞれ前記ツメ部Ｅ，Ｆ，Ｇ，Ｈが設けられている一方、前記ラチェットリング２の前記円周部４の内周面ｍと前記ラチェットギア１の外面との間でツメ部Ｅ，Ｆ，Ｇ，Ｈを介して空間１１が形成されている。すなわち、円周部４の肉厚ｄを薄肉にすることで、つまり、ツメ部Ｅ，Ｆ，Ｇ，Ｈの肉付けを無くすことで、温度調整用ハンドルの回転操作時の柔軟性が生まれ、温度調整用ハンドルの回転操作における「カチカチ」という操作音の緩和が可能である。   Furthermore, in this embodiment, a plurality of recesses 10 (four recesses in this embodiment) are formed on the outer peripheral surface 4a of the circumferential portion 4 of the ratchet ring 2 with an appropriate predetermined interval. The claw portions E, F, G, and H are respectively provided directly below the recesses 10, while the inner peripheral surface m of the circumferential portion 4 of the ratchet ring 2 and the outer surface of the ratchet gear 1. A space 11 is formed between the claws E, F, G, and H. That is, by reducing the thickness d of the circumferential portion 4, that is, by eliminating the fleshing of the claws E, F, G, and H, flexibility during the rotation operation of the temperature adjustment handle is created, and the temperature It is possible to mitigate the operation sound of “tick” in the rotation operation of the adjustment handle.
