Description
本発明は、湯と水を混合して吐水する湯水混合水栓に係り、特に高温時の吐水に対する安全性を高めるために、高温吐水設定時に操作を必要とする安全ボタンを備えた湯水混合水栓に関する発明である。 The present invention relates to a hot and cold water mixing faucet that mixes hot water and water to discharge water, and in particular, to increase safety against water discharge at high temperatures, hot water mixed water having a safety button that requires an operation when setting high temperature water discharge. This invention relates to a stopper.
従来の湯水混合水栓においては、使用者が温度調節ハンドルを高温側へ回転操作する際に、一気に高温側へ回転してしまうと危険を伴うため、温度調節ハンドル外周面から突出する安全ボタンが具備されており、温度調節ハンドルの高温側への回転途中で回転が規制され、その規制の解除のためには安全ボタンの操作を必要とすることで、一気に高温側へ回転する誤操作を防止している（例えば、特許文献１参照。）。 In a conventional hot and cold water faucet, when the user rotates the temperature adjustment handle to the high temperature side, there is a danger if the user rotates it to the high temperature side at once, so there is a safety button protruding from the outer peripheral surface of the temperature adjustment handle. Rotation is restricted during the rotation of the temperature adjustment handle to the high temperature side, and the operation of the safety button is required to release the restriction, preventing erroneous operation that rotates to the high temperature side at once. (For example, refer to Patent Document 1).
この安全ボタンの突出量は、安全ボタンの押し込み操作による規制解除を行って、温度調節ハンドルを高温側に回転させた状態では小さくなるが、一方、適温、低温側においては安全ボタンは温度調節ハンドル外周面から大きく突出したままとなっている。
そのため、適温、低温側において大きく突出している安全ボタンを押し込んで一気に高温側まで回転させることが可能であり、その場合には意図せずに高温水が吐水される恐れがあった。
また、使用頻度の高い適温や低温に設定された状態で温度調節ハンドル外周に安全ボタンが大きく突出しているため、温度調節ハンドルの意匠性や清掃性の面でも問題があった。
The amount of protrusion of the safety button is reduced when the restriction is released by pushing the safety button and the temperature adjustment handle is rotated to the high temperature side. On the other hand, the safety button is at the appropriate temperature and low temperature side. It remains largely protruding from the outer peripheral surface.
Therefore, it is possible to push the safety button that protrudes greatly at the appropriate temperature and low temperature side and rotate it at a stretch to the high temperature side. In that case, there is a possibility that the high temperature water is unintentionally discharged.
In addition, since the safety button protrudes from the outer periphery of the temperature control handle in a state where the temperature is set to a suitable temperature and low temperature, which are frequently used, there is a problem in terms of design and cleanability of the temperature control handle.
本発明は、上記問題を解決するためになされたもので、本発明の課題は、安全ボタンを操作する必要がない状態における温度調節ハンドルからの突出量を小さくすることで、誤って安全ボタンを操作したまま高温吐水されてしまうことを防止し、また、温度調節ハンドルの意匠性や清掃性を向上させることを目的とするものである。 The present invention has been made in order to solve the above-described problems, and an object of the present invention is to reduce the amount of protrusion from the temperature adjustment handle in a state where it is not necessary to operate the safety button, thereby erroneously attaching the safety button. It is intended to prevent high-temperature water discharge while being operated, and to improve the design and cleanability of the temperature control handle.

In order to achieve the above object, according to the first aspect of the present invention, the hot water mixing means for changing the discharged water temperature by adjusting the mixing ratio of hot water and water, and the setting of the discharged water temperature by the hot water mixing means. A temperature control handle that is rotated, a safety button that is movable in a radial direction of the temperature control handle and is biased in a direction protruding from the outer periphery by a biasing means, and a mounting surface of the temperature control handle A rotation regulating wall that regulates rotation by contacting a part of the safety button in a state of being protruded by the urging means while the temperature adjustment handle is being rotated from the low temperature setting side to the high temperature setting side. in mixing valve having a mounting surface of the temperature control handle, wherein the temperature regulating handle lower setpoint temperature from the state in which a part of the safety button is in contact with the rotation restricting wall When rotated, characterized in that the protruding amount restricting wall safety button against the biasing force of said biasing means moving in a direction housed in said temperature regulating handle is formed.
従って、温度調節ハンドルの高温設定側への回転規制を行う必要が無い回転領域では、安全ボタンの温度調節ハンドルから突出量を小さくすることで、誤って安全ボタンを押し込んで高温設定領域まで回転されることがなく、意図せずに高温吐水されてしまうことを防止できる。また、温度調節ハンドルから安全ボタンが大きく突出する回転範囲が減ることで、温度調節ハンドルの意匠性や清掃性を向上させることができる。
Therefore, in the rotation area it is not necessary to perform a rotation regulation of higher setpoint temperature of the temperature regulating handle, by reducing the projection amount from the temperature regulating handle of the safety button, to a high temperature setting area I Push the accidental safety button It is not rotated, and it is possible to prevent unintentional hot water discharge. Moreover, the design range and the cleaning property of the temperature control handle can be improved by reducing the rotation range in which the safety button protrudes greatly from the temperature control handle.
また、請求項２記載の発明によれば、前記湯水混合水栓は、前記温度調節ハンドルの周面の一部を覆い、一部を露出するカバーを備えており、前記安全ボタンは、前記突出量規制壁によって前記温度調節ハンドル内に収納する方向に移動している間は前記カバーに覆われ、前記突出量規制壁による規制を外れて突出して前記回転規制壁に当接するまでの間は前記カバーより露出することを特徴とする。これにより、温度調節ハンドルの高温設定側への回転規制を行う必要が無い回転領域では、安全ボタンがカバーによって覆われるので、使用者は安全ボタンに触ることができなくなり、より確実に誤って安全ボタンを押し込んで高温設定領域まで回転されることを防止できる。また、温度調節ハンドルの天面をカバーから突出させる必要がないので、意匠性に優れた湯水混合水栓を提供することが可能となる。

次いで温度調節ハンドル１２について説明する。
図６は、温度調節ハンドル１２によって操作される湯水混合手段としての温度調節弁１８の断面図であり、図７は分解斜視図である。温度調節弁１８はサーモスタット式の湯水混合弁であり、給水管及び給湯管を通じて供給された湯と水は、温度調節ハンドル１２によって所望に設定された温度となるように湯と水の混合比が自動調節される。温度調節ハンドル１２は水栓本体１０に内蔵された温度調節弁１８のスピンドル１９先端に取付けビス２４によりネジ止めされ、スピンドル１９と供回りしてスピンドル１９の軸心周りに回転自在となるよう取付けられ、ネジ止め箇所はキャップ２０により被覆されている。
Next, the temperature adjustment handle 12 will be described.
FIG. 6 is a cross-sectional view of the temperature control valve 18 as hot water mixing means operated by the temperature control handle 12, and FIG. 7 is an exploded perspective view. The temperature control valve 18 is a thermostat type hot and cold water mixing valve. The hot water and the water supplied through the hot water supply pipe and the hot water supply pipe have a mixing ratio of hot water and water so that the temperature set by the temperature control handle 12 becomes a desired temperature. Automatically adjusted. The temperature control handle 12 is screwed to the tip of the spindle 19 of the temperature control valve 18 built in the faucet body 10 with a mounting screw 24 so that the temperature control handle 12 can be rotated around the axis of the spindle 19 along with the spindle 19. The screwing point is covered with a cap 20.
温度調節ハンドル１２の前面１２ａは上カバー前面１４ｂと略同一面となるよう構成されるとともに、温度調節ハンドル１２の周面の一部は上カバー１４により覆われている。 また、温度調節ハンドル１２の前面１２ａには、温度調節ハンドル１２の操作を容易にするための操作レバー２１が湯水混合水栓１の前面に突出するように設けられている。
The front surface 12 a of the temperature control handle 12 is configured to be substantially flush with the upper cover front surface 14 b, and a part of the peripheral surface of the temperature control handle 12 is covered with the upper cover 14. An operation lever 21 for facilitating the operation of the temperature adjustment handle 12 is provided on the front surface 12 a of the temperature adjustment handle 12 so as to protrude from the front surface of the hot and cold water mixing tap 1.
図８は温度調節ハンドル１２の断面図である。この温度調節ハンドル１２の内周面には温度調節ハンドル１２の回転を規制する安全ボタン２２が温度調節ハンドル１２の取付孔２３を通じて半径方向に移動可能なように取付けられている。より詳細に説明すると、安全ボタン２２は、水栓本体１０側と係合することで、温度調節ハンドル１２の回転を規制するストッパー２６と、ストッパー２６を温度調整ハンドル１２の外径方向に付勢する付勢手段としての付勢バネ２７とを介して、固定ビス２８により温度調節ハンドル１２に取付けられている。また、温度調節弁１８側には、温度調節ハンドル１２の回転規制部２９がナット３０により水栓本体１０に固定されている。
FIG. 8 is a cross-sectional view of the temperature adjustment handle 12. A safety button 22 for restricting the rotation of the temperature adjustment handle 12 is attached to the inner peripheral surface of the temperature adjustment handle 12 so as to be movable in the radial direction through an attachment hole 23 of the temperature adjustment handle 12. More specifically, the safety button 22 is engaged with the faucet body 10 side to thereby urge the stopper 26 to restrict the rotation of the temperature adjustment handle 12 and the stopper 26 in the outer diameter direction of the temperature adjustment handle 12. It is attached to the temperature adjustment handle 12 by a fixing screw 28 via a biasing spring 27 as a biasing means. Further, on the temperature adjustment valve 18 side, a rotation restricting portion 29 of the temperature adjustment handle 12 is fixed to the faucet body 10 by a nut 30.
図９は、回転規制部２９の断面図である。この回転規制部２９には、低温設定側から高温設定側へと回転操作される途中において、付勢バネ２７により温度調節ハンドル１２の外径方向に押しつけられたストッパー２６と当接して温度調節ハンドル１２の回転を規制する回転規制壁２５と、ストッパー２６が回転規制壁２５に当接した状態から温度調節ハンドル１２を低温設定側に回転させた際に安全ボタン２２の付勢バネ２７の付勢力に抗して使用者が安全ボタン２２を操作することなく温度調節ハンドル１２内に徐々に収納する方向に移動させる突出量規制壁３１が形成されている。
FIG. 9 is a cross-sectional view of the rotation restricting portion 29. The rotation restricting portion 29 is in contact with the stopper 26 pressed in the outer diameter direction of the temperature adjustment handle 12 by the biasing spring 27 during the rotation operation from the low temperature setting side to the high temperature setting side. When the temperature adjustment handle 12 is rotated to the low temperature setting side from the state where the rotation restricting wall 25 restricting the rotation of the twelve rotation and the stopper 26 is in contact with the rotation restricting wall 25, the urging force of the urging spring 27 of the safety button 22 On the other hand, a protrusion amount regulating wall 31 is formed that allows the user to move it in the direction in which it is gradually housed in the temperature control handle 12 without operating the safety button 22.
具体的に温度調節ハンドル１２を操作した時の動作について説明する。図９において安全ボタン２２がＡの位置（低温設定側）から、安全ボタン２２がＢの位置（適温設定側）となるように温度調節ハンドル１２を回転操作した場合においては、安全ボタン２２は突出量規制壁３１に沿って温度調節ハンドル１２の外周部へ突出する。そして、更に温度調節ハンドル１２を回転させて安全ボタン２２がＣの位置となると、ストッパー２６と回転規制壁２５が当接することで、温度調節ハンドル１２の回転は規制されて一気に高温設定側へ回転して意図せずに高温吐水される危険を回避することができる。
The operation when the temperature adjustment handle 12 is specifically operated will be described. In FIG. 9, when the temperature adjustment handle 12 is rotated so that the safety button 22 is in the position A (low temperature setting side) and the safety button 22 is in the position B (appropriate temperature setting side), the safety button 22 protrudes. It protrudes along the amount regulating wall 31 to the outer peripheral portion of the temperature control handle 12. When the temperature control handle 12 is further rotated and the safety button 22 is in the position C, the stopper 26 and the rotation restricting wall 25 come into contact with each other, so that the rotation of the temperature control handle 12 is restricted and rotates to the high temperature setting side at once. Thus, it is possible to avoid the risk of unintentional hot water discharge.
高温吐水が必要な場合においては、使用者が意図して安全ボタン２２を温度調節ハンドル１２の内径側へ付勢バネ２７の付勢力に抗して押し込み、ストッパー２６と回転規制壁２５の当接を解除しながら温度調節ハンドル１２を高温設定側へ回転することで高温吐水を得ることができる。一方、温度調節ハンドル１２を高温設定側から適温設定側へ回転操作して安全ボタン２２がＣの位置に戻す場合においては、使用者が安全ボタン２２を操作する必要はない。 When high temperature water discharge is required, the user intentionally pushes the safety button 22 into the inner diameter side of the temperature adjustment handle 12 against the urging force of the urging spring 27, and the stopper 26 and the rotation regulating wall 25 come into contact with each other. The hot water discharge can be obtained by rotating the temperature adjustment handle 12 to the high temperature setting side while releasing the. On the other hand, when the temperature adjustment handle 12 is rotated from the high temperature setting side to the appropriate temperature setting side to return the safety button 22 to the position C, the user does not need to operate the safety button 22.
そして、安全ボタン２２がＣの位置にある適温設定側から更に温度調節ハンドル１２を回転させて安全ボタン２２がＡの位置となる低温設定側まで回転させる際には、突出量規制壁３１の傾斜に沿って滑らかにストッパー２６が移動する。このため、高温設定側から低温設定側へ回転操作する場合においては、回転規制部２９に設けられた突出量規制壁３１により付勢バネ２７の付勢力に抗して温度調節ハンドル１２内側へ収納する方向へ移動させ安全ボタン２２の突出量を小さくすることができる。
When the temperature adjustment handle 12 is further rotated from the appropriate temperature setting side where the safety button 22 is at the C position to the low temperature setting side where the safety button 22 is at the A position , the inclination of the protruding amount regulating wall 31 is increased. The stopper 26 moves smoothly along For this reason, when rotating from the high temperature setting side to the low temperature setting side, the protrusion amount regulating wall 31 provided in the rotation regulating portion 29 is housed inside the temperature adjustment handle 12 against the urging force of the urging spring 27. The amount of protrusion of the safety button 22 can be reduced by moving it in the direction of movement.
このように高温設定側へ回転規制を行う必要がない回転領域において安全ボタン２２の温度調節ハンドル１２からの突出量を小さくすることで、誤って安全ボタン２２を押し込んで高温設定領域まで回転させてしまうことがなく、意図せずに高温吐水されることを防止できる。 Thus, by reducing the protrusion amount of the safety button 22 from the temperature adjustment handle 12 in the rotation region where it is not necessary to regulate the rotation to the high temperature setting side, the safety button 22 is accidentally pushed and rotated to the high temperature setting region. Therefore, it is possible to prevent unintentional hot water discharge.
更に本実施例において、温度調節ハンドル１２の外周面から安全ボタン２２が大きく突出される回転領域においては上カバー１４から安全ボタン２２が露出するとともに、安全ボタン２２の突出量が小さくなる回転領域では安全ボタン２２が上カバー１４で覆われるように構成されている。このため、使用者は操作が不要な位置において安全ボタン２２に触れることができなくなり、誤って安全ボタン２２を押し込んで高温設定領域まで回転されることをより確実に防止できる。また、安全ボタン２２を温度調節ハンドル１２の外周面に突出させるために温度調節ハンドル１２を湯水混合水栓１の前面よりも突出させる必要がないので、意匠性に優れた湯水混合水栓１を提供することが可能になる。 Further, in the present embodiment, in the rotation region where the safety button 22 is largely projected from the outer peripheral surface of the temperature control handle 12, the safety button 22 is exposed from the upper cover 14, and in the rotation region where the protrusion amount of the safety button 22 is small. The safety button 22 is configured to be covered with the upper cover 14. For this reason, the user cannot touch the safety button 22 at a position where no operation is required, and can more reliably prevent the safety button 22 from being accidentally pushed and rotated to the high temperature setting region. Further, since the temperature control handle 12 does not need to be protruded from the front surface of the hot and cold water mixing faucet 1 in order to make the safety button 22 protrude from the outer peripheral surface of the temperature control handle 12, the hot and cold water mixing faucet 1 having excellent design is provided. It becomes possible to provide.
