【発明の属する技術分野】
本発明は、便器の上面に載設される洗浄水タンクにおける排水操作をするための機構に関し、詳しくは、タンクの正面側に操作ハンドルを設けた場合に起こる不具合の解消を目的とする。
【0002】
【従来の技術】
図5に示すように、便器S上に載設される洗浄水タンクTは、一般に左右の幅寸法αの方が前後の奥行き寸法βよりも大きく設定され、排水操作用のハンドルHはタンクTの側面に取り付けられる。しかるに図6の如く、タンクTの左右にキャビネットCを配置したり、タンクT自体をキャビネットC内に収納する構成を採用する場合、ハンドルHは、タンクTの正面部に取り付けられる。そしてこのとき、ハンドルHの位置は、開き上げた便座30,便蓋31との干渉を避けるため、タンク正面部における左右いずれかの側縁寄りに配置される。
【0003】
図5のように、ハンドルHをタンクTの側面に取り付けた場合、ハンドルHに連結されるレバーLは、タンクTの幅方向とほぼ平行に配置され、ハンドル操作に伴うレバーLの回動方向は、タンクTの前後方向となる。また、レバーLの先端部を、フロート弁等の排水弁装置Fの直上またはその近くへ容易に位置させることができるから、鎖等の連係手段Rをほぼ鉛直な姿勢にすることができる。従って、特許文献1に記載するような排水弁装置(フロート弁)に対し、レバーLの回動方向を変更することによって、洗浄水量の大小切替操作を確実に行うことができる。
【0004】
これに対し図6の如く、ハンドルHをタンクT正面部の左右いずれかの側縁寄りに取り付けたときは、レバーLの先端部が排水弁装置Fの直上に位置しないため、レバーLと排水弁装置Fとを連結する鎖等の連係手段Rが斜めに伸びることとなる。このため、レバーLの回動方向の違いでストロークに差をつけにくく、洗浄水量の大小切替が困難であった。
【0005】
そこで、洗浄水タンクの正面における中央から離れた位置に、操作ハンドルを取り付けた場合の前記問題を解決する一手段が、特許文献2に記載されている。同特許文献2には、タンクの中央から離れた位置に設けた操作ハンドルと、タンク中央部に設けた排水弁装置の開閉操作器具とを、リンク機構やプーリー機構で連結した洗浄水タンク装置が記載されている。そして、タンク側方の操作ハンドルを操作することにより、リンク機構等を介して、タンク中央部の開閉操作器具を動作させ、排水弁装置の開閉を操作することができるようなされている。従って当該装置は、排水弁装置に対する引き上げ操作をほぼ直上位置から行うことが可能なので、洗浄水量の大小切替を実行するのが容易である。

特開平11−100881号公報
【0007】
【発明が解決しようとする課題】
前記特許文献2に記載されたものは、排水弁装置の開閉操作器具が、タンクの正面側に設けられる操作ハンドルの回動方向と同じ方向、つまりタンクの左右方向に回動するよう構成されている。そのため排水弁装置が、例えば図7〜10に示す如く、開閉操作をするのに、開閉操作器具をタンクの前後方向に回動させることを要するような構造である場合(特許文献1の第5実施例参照)、前記特許文献2の技術は適用することができなかった。
【0008】
【課題を解決するための手段】
本発明が前記従来の問題点を解決するために創案した洗浄水タンクの排水機構の特徴を、図面を参照して説明すると、タンク外面の正面部における左右いずれかの側縁寄りへ回動可能に取り付けられる操作ハンドルHと、タンク内に設けられ前記操作ハンドルHの回動軸Jと交叉するか又は食い違うように設定された回動軸L−1を有し長手方向の軸芯回りに回動可能なレバーLと、タンクの底部に設けた排水弁装置Fと、前記レバーLと排水弁装置Fとを連動可能に接続する鎖等の連係手段Rと、タンク内に設けられ前記操作ハンドルHの回動軸Jと前記レバーLの回動軸L−1とを連動可能に連結する変向伝動手段Kとを備え、前記操作ハンドルHを回動させると前記変向伝動手段Kを介して前記レバーLがタンクの前後方向に回動するように構成されていることにある。
【0009】
前記構成により、前記操作ハンドルHをタンクの正面部に取り付けたときに、前記レバーLの回動軸L−1を、前記操作ハンドルHの回動軸Jに対し、変向伝動手段Kを介して実質的に直角となるように連結することができるから、レバーLを、タンクの左右幅方向とほぼ平行な姿勢にできると共に、レバーLの先端部を排水弁装置Fの直上又はその近くに位置させることが容易となる。それ故、レバーLと排水弁装置Fとを接続する鎖等の連係手段Rをほぼ鉛直な姿勢に保てるので、ハンドルHの回動方向による洗浄水量の大小切替操作を確実にできる。またレバーLの回動方向をタンクの前後方向に設定できるから、開閉動作をするのにレバーLをタンクの前後方向に回動させることを要する種類の排水弁装置に対応することが可能となる。
【0010】
なお本発明の実施に当たり、前記変向伝動手段Kは、かさ歯車より構成することが考えられる。この場合、通常のかさ歯車は、二つの回動軸が同一平面において直交するように配置されるものであるが、状況に応じて食い違いかさ歯車を用いれば、各回動軸が会合しないように二つの歯車を配置することが可能である。
【0011】
また前記操作ハンドルHの回動軸Jを、前記変向伝動手段Kに対し軸線方向に摺動可能に構成することが望ましい。あるいは、前記レバーLの回動軸L−1を、前記変向伝動手段Kに対し軸線方向に摺動可能に構成することも可能である。なお、操作ハンドルHの回動軸J及び/又はレバーLの回動軸L−1を、変向伝動手段Kに対し軸線方向に摺動可能に構成した結果、回動軸どうしが会合する可能性のある場合は、変向伝動手段Kを、前述の食い違いかさ歯車を用いて構成すればよい。
【0012】
【発明の実施の形態】
本発明の実施形態を、図1乃至図4を用いて説明する。本発明に係る洗浄水タンクの排水機構Dは、排水弁装置Fが例えば図7〜図10に示す如き構造(特許文献1の第5実施例参照)である場合において、操作ハンドルHをタンクTの正面部へ取り付ける必要があるときに適用されるものである。
【0013】
本例の排水機構Dにあっては、操作ハンドルHの回動軸Jと、レバーLの回動軸L−1とを互いに直角に交叉するよう配置すると共に、ハンドルHの回動軸JとレバーLの回動軸L−1とを変向伝動手段Kで連結して、ハンドルHをタンクTの正面側から左右方向へ回動操作すると、レバーLが、タンクTの前後方向に回動するように構成したところに特色を有している。なお本例において、レバーLと排水弁装置Fとを接続する連係手段Rには、従来の玉鎖を使用できる。
【0014】
本例の変向伝動手段Kは、ハウジング1内に収められた一組のかさ歯車2,3から成り、各回転軸が互いに直交するよう設定されている。但し、状況に応じ、回転軸の軸線の交叉角度を90°以外に設定することも妨げない。また、かさ歯車2,3のギア比は、通常1:1とされるが、必要に応じ異なるギア比を採用することも妨げない。上記変向伝動手段Kを取り付けるには、ハウジング1にブラケット部12を設け、これを例えば洗浄水タンクが二重壁構造である場合のインナータンク10か或いは別途設けた支持部材に形成した切欠部11に挿入し、ブラケット部12の突出部分にクリップ13を嵌合させることで固定するという構造を採用できる。
【0015】
前記レバーLの回動軸L−1は、変向伝動手段Kに設けられる一方のかさ歯車2に、一体的に回動するよう接続される。レバーLとハウジング1との間には、軸受4が介装される。もう一方のかさ歯車3には、ハンドルHの回動軸Jに設けた角柱部J−1を接続する。但し、この角柱部J−1は、かさ歯車3に対し、軸回りに一体的に回動するが、軸線方向へは摺動可能に構成されている。また、ハンドルHの回動軸Jにおける手前側適所が、タンクTの正面部に適宜ストッパー15を用いて固定した軸受14により、回動自在に保持されている。
【0016】
このようにハンドルHの角柱部J−1を、かさ歯車3に対し摺動して進退可能とすることにより、タンクTの寸法変更のためハンドルHから変向伝動手段Kまでの間隔が増減する場合でも、容易な対応が可能となる。なお、上記かさ歯車3とハウジング1との間には、軸受5を介装することが望ましい。
【0017】
また図4に示す如く、レバーLの回転軸L−1に角柱部L−2を設け、レバーLについても、かさ歯車2に対し摺動可能な構成とすることが考えられる。これにより、タンクTの寸法変更のため変向伝動手段Kから排水弁装置Fまでの間隔が増減する場合に、対応が容易となる。なお、ハンドルHの回動軸J及びレバーLの回動軸L−1を両方ともかさ歯車2,3に対し摺動可能とする場合は、上記二つの角柱部J−1,L−2が会合するのを避けるため、かさ歯車2,3を食い違いかさ歯車とするのが望ましい。
【0018】
前記の如く構成した本発明の排水機構Dは、タンクTの正面部に設けたハンドルHを操作すると、変向伝動手段K内の一方のかさ歯車3が回動し、これと連動してもう一方のかさ歯車2が回動するため、タンクTの幅方向に対し実質的に平行に配置したレバーLが回動する。その結果、レバーLの先端部に適宜の接続具16で取着した玉鎖等の連係手段Rを通じ、排水弁装置Fが開き上げられ、洗浄水の排水が開始される。
【0019】
本発明では、レバーLの先端部を排水弁装置Fの直上又はその近傍位置に配置できるから、連係手段Rをほぼ鉛直な状態とすることができ、それ故、レバーLの回動量の多寡を、連係手段Rの引っ張り量に正確に反映させることが可能である。従って、例えば、ハンドルH及びレバーLの回動方向の違いによって、かさ歯車2,3の回動量が制限される手段6を変向伝動手段Kに設けておけば、ハンドルHの回動方向により、排水弁装置Fの開き上げ量を異ならせて、洗浄水の排水量を確実に変化させることができる。すなわち、タンク正面部に操作ハンドルを設けたものにおいて、洗浄水量の大小切替を確実に実現できる。
【0020】
ここで、本発明に係る排水機構Dの適用対象となる排水弁装置F1の一例を、図7〜図10に基づいて簡単に説明する。この排水弁装置F1は、例えば水洗便器用の洗浄水タンクの底部に設けられるものであり、固定金具22,球弁26,切替弁部材60を主要な構成部材としている。固定金具22は、パッキン23と締付ナット24を介してタンク底部に取り付けられる筒状のものであり、下端部は排水口21となされている。その内部にはガイド片22bと弁座ガイド50とが設けられ、上端側には皿状の弁座部22aが形成されている。また、固定金具22には、オーバーフロー管25が連通状に立設されている。
【0021】
固定金具22の弁座部22aに着座する球弁26は、その上面に突設した連結突起26a上端の係入片26bを、水受カップ51の底部に設けた係合突部58に嵌め込んで、止リング59を嵌着することにより、水受カップ51と着脱可能に連結される。また頂部下面からガイド棒27が垂設され、ガイド棒27は、固定金具22に設けたガイド片22b及び弁座ガイド50のガイド孔50aに挿通されている。
【0022】
水受カップ51は、その側面に連結部52及びガイド筒53が設けられ、このガイド筒53はオーバーフロー管55に昇降可能に外嵌されている。なおオーバーフロー管55の上端部には、ストッパー部材66が嵌着されている。水受カップ51の底面部51aには、中心から偏心する位置に傾斜部54が形成され、傾斜部54には方形の流出孔55が形成されている。56は当接ストッパー片である。水受カップ51の上縁には、軸孔57aを有する一対の立上片57が対向するように立設され、軸孔57aに、切替弁部材60の回動軸61が支持されている。
【0023】
切替弁部材60は、回動軸61の中心部からガイド筒部62が垂設され、ガイド筒部62内を貫通し且つ上下に摺動可能なスピンドル63が、スプリングSPにより常時下方へ付勢された状態で組み込まれている。スピンドル63の下端部には方形弁体64が、上端部には球鎖Rを係止するための鎖フック65がそれぞれ設けられている。
【0024】
切替弁部材60は、回動軸61を支点として水受カップ51内で傾動可能なものであって、その傾動方向は、タンクの前後方向に設定されている。そして、球鎖Rを図10のX側(タンク後方)へ引っ張ったときには、仮想線(二点鎖線)の如く傾動して、流出孔55を開放した状態に維持するから、大水量の洗浄水排出となる。反対に球鎖Rを図10のY側(タンク前方)へ引っ張ったときには、切替弁部材60が実線の如く傾動して、スピンドル63下端部の方形弁体64が流出孔55を閉止した状態に維持するから、水受カップ51内に水が溜まった状態となる。その結果、水受カップ51に貯留された水の重みで球弁26の下降速度が増加するから、排水時間が短縮され、少量の洗浄水排出となる。
【0025】
このように前述の排水弁装置F1は、排水量の大小切替をするために、切替弁部材60をタンクの前後方向に移動させることを要する。しかるに本発明を適用することにより、タンク正面に操作ハンドルを設けた場合でも、前記排水弁装置F1を操作することが可能となる。
【0026】
ところで、本発明の実施の形態は、前記に限定されるものではない。例えば、変向伝動手段Kを、かさ歯車以外に、ハンドルHの回動軸Jと、レバーLの回動軸L−1とを、コイルバネで連結する構成が考えられる。その他、本発明は、実施の状況に応じ適宜変更することを妨げない。
【0027】
【発明の効果】
本発明に係る排水機構によれば、レバーの先端部を排水弁装置の直上またはその近くに位置させることができるので、レバーと排水弁装置とを接続する連係手段をほぼ鉛直な状態にできる。それ故、レバーの回動量の変化を、連係手段の引っ張り量に正確に反映させることができるから、洗浄水量の確実な大小切替が可能となる。
【0028】
また、タンクの正面部に取り付けたハンドルを操作して、タンクの幅方向とほぼ平行に配置したレバーを、タンクの前後方向に回動させることができるので、連係手段をタンクの前後方向に引っ張ることが開閉動作に必要な種類の従来の排水弁装置を、そのまま利用することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a mechanism for performing a drain operation in a wash water tank mounted on the upper surface of a toilet bowl, and more specifically, an object of the present invention is to eliminate problems that occur when an operation handle is provided on the front side of the tank.
[0002]
[Prior art]
As shown in FIG. 5, the wash water tank T placed on the toilet bowl S is generally set such that the left and right width dimension α is larger than the front and rear depth dimension β, and the drainage operation handle H is a tank T. It is attached to the side of the. However, as shown in FIG. 6, when the cabinet C is arranged on the left and right of the tank T, or the tank T itself is housed in the cabinet C, the handle H is attached to the front portion of the tank T. At this time, the position of the handle H is arranged near either the left or right side edge in the front part of the tank in order to avoid interference with the toilet seat 30 and the toilet lid 31 that are opened up.
[0003]
As shown in FIG. 5, when the handle H is attached to the side surface of the tank T, the lever L connected to the handle H is arranged substantially parallel to the width direction of the tank T, and the turning direction of the lever L accompanying the handle operation Is the front-rear direction of the tank T. Moreover, since the front-end | tip part of the lever L can be easily located in the immediate vicinity of the drain valve apparatus F, such as a float valve, or its vicinity, linkage means R, such as a chain | strand, can be made into a substantially vertical attitude | position. Therefore, by changing the rotation direction of the lever L with respect to the drain valve device (float valve) as described in Patent Document 1, the switching operation of the washing water amount can be reliably performed.
[0004]
On the other hand, as shown in FIG. 6, when the handle H is attached to either the left or right side edge of the front surface of the tank T, the tip of the lever L is not located directly above the drain valve device F. The linkage means R such as a chain connecting the valve device F extends obliquely. For this reason, it is difficult to make a difference in stroke due to the difference in the rotation direction of the lever L, and it is difficult to switch the amount of washing water.
[0005]
Therefore, Patent Document 2 describes one means for solving the above problem when an operation handle is attached at a position away from the center on the front surface of the cleaning water tank. Patent Document 2 discloses a washing water tank device in which an operation handle provided at a position away from the center of a tank and an opening / closing operation tool for a drain valve device provided at the center of the tank are connected by a link mechanism or a pulley mechanism. Are listed. By operating an operation handle on the side of the tank, an opening / closing operation tool at the center of the tank can be operated via a link mechanism or the like to open / close the drain valve device. Therefore, the apparatus can perform the pulling up operation with respect to the drain valve device from the position immediately above, so that it is easy to switch the amount of the washing water.
[0006]

Japanese Patent Application Laid-Open No. 11-100811
[Problems to be solved by the invention]
The device described in Patent Document 2 is configured such that the opening / closing operation tool of the drain valve device rotates in the same direction as the rotation direction of the operation handle provided on the front side of the tank, that is, in the left-right direction of the tank. Yes. Therefore, for example, as shown in FIGS. 7 to 10, the drain valve device has a structure that requires the opening / closing operation tool to be rotated in the front-rear direction of the tank in order to perform the opening / closing operation (No. 5 of Patent Document 1). The technique of the said patent document 2 was not able to be applied.
[0008]
[Means for Solving the Problems]
Referring to the drawings, the features of the drainage mechanism of the cleaning water tank created in order to solve the above-mentioned conventional problems can be rotated to the left or right side edge of the front part of the outer surface of the tank. And an operation handle H attached to the operation handle H, and a rotation axis L-1 provided in the tank and set so as to cross or conflict with the rotation axis J of the operation handle H. A movable lever L, a drain valve device F provided at the bottom of the tank, a linkage means R such as a chain for connecting the lever L and the drain valve device F in an interlockable manner, and the operation handle provided in the tank A turning transmission means K for connecting the turning axis J of H and the turning axis L-1 of the lever L so as to be interlocked with each other is provided, and when the operation handle H is turned, the turning transmission means K is interposed. The lever L rotates in the longitudinal direction of the tank. In that it is configured urchin.
[0009]
With the above configuration, when the operation handle H is attached to the front portion of the tank, the rotation axis L-1 of the lever L is connected to the rotation axis J of the operation handle H via the direction change transmission means K. The lever L can be in a posture substantially parallel to the left-right width direction of the tank, and the tip end of the lever L is directly above or near the drain valve device F. It is easy to position. Therefore, since the linkage means R such as a chain connecting the lever L and the drain valve device F can be maintained in a substantially vertical posture, the operation of switching the amount of washing water depending on the rotation direction of the handle H can be ensured. Further, since the rotation direction of the lever L can be set in the front-rear direction of the tank, it is possible to cope with a drain valve device of a type that requires the lever L to be rotated in the front-rear direction of the tank in order to perform the opening / closing operation. .
[0010]
In implementing the present invention, it is conceivable that the deflection transmission means K is constituted by a bevel gear. In this case, a normal bevel gear is arranged such that two rotation shafts are orthogonal to each other in the same plane, but if a bevel gear bevel gear is used depending on the situation, the two rotation shafts do not meet each other. It is possible to arrange two gears.
[0011]
Further, it is desirable that the rotation axis J of the operation handle H is configured to be slidable in the axial direction with respect to the direction change transmission means K. Alternatively, the rotation axis L-1 of the lever L can be configured to be slidable in the axial direction with respect to the deflection transmission means K. Note that the rotation axis J of the operation handle H and / or the rotation axis L-1 of the lever L is configured to be slidable in the axial direction with respect to the direction change transmission means K, so that the rotation axes can meet each other. In the case where there is a characteristic, the deflection transmission means K may be configured by using the above-mentioned staggered bevel gear.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. The drainage mechanism D of the cleaning water tank according to the present invention is configured so that the operation handle H is connected to the tank T when the drainage valve device F has a structure as shown in FIGS. 7 to 10 (see the fifth embodiment of Patent Document 1). It is applied when it is necessary to attach to the front part of the.
[0013]
In the drainage mechanism D of this example, the rotation axis J of the operation handle H and the rotation axis L-1 of the lever L are arranged so as to cross each other at right angles, and the rotation axis J of the handle H is When the turning shaft L-1 of the lever L is connected by the direction change transmission means K and the handle H is turned from the front side of the tank T in the left-right direction, the lever L turns in the front-rear direction of the tank T. It has a special feature where it is configured to do so. In this example, a conventional ball chain can be used as the linking means R for connecting the lever L and the drain valve device F.
[0014]
The diverting transmission means K of this example includes a pair of bevel gears 2 and 3 housed in the housing 1 and is set so that the rotation axes are orthogonal to each other. However, setting the crossing angle of the axis of the rotation axis to other than 90 ° according to the situation is not hindered. Moreover, although the gear ratio of the bevel gears 2 and 3 is usually 1: 1, it is not hindered to adopt a different gear ratio as necessary. In order to attach the direction change transmission means K, a bracket portion 12 is provided in the housing 1, and this is formed in, for example, the inner tank 10 when the washing water tank has a double wall structure or a notch portion formed in a separately provided support member. 11 and can be fixed by fitting the clip 13 to the protruding portion of the bracket portion 12.
[0015]
The rotation axis L-1 of the lever L is connected to one bevel gear 2 provided in the direction change transmission means K so as to rotate integrally. A bearing 4 is interposed between the lever L and the housing 1. The other bevel gear 3 is connected to a prism portion J-1 provided on the rotation axis J of the handle H. However, this prismatic portion J-1 rotates integrally around the axis with respect to the bevel gear 3, but is configured to be slidable in the axial direction. Further, an appropriate position on the front side of the rotation axis J of the handle H is rotatably held by a bearing 14 that is appropriately fixed to the front portion of the tank T using a stopper 15.
[0016]
Thus, by making the prismatic portion J-1 of the handle H slidable with respect to the bevel gear 3, the distance from the handle H to the direction change transmission means K is increased or decreased for changing the size of the tank T. Even in this case, easy handling is possible. A bearing 5 is preferably interposed between the bevel gear 3 and the housing 1.
[0017]
Further, as shown in FIG. 4, it is conceivable that a prismatic portion L-2 is provided on the rotation axis L-1 of the lever L, and the lever L is also slidable with respect to the bevel gear 2. Thereby, when the space | interval from the direction change transmission means K to the drain valve apparatus F increases / decreases for the dimension change of the tank T, a response | compatibility becomes easy. When both the rotation axis J of the handle H and the rotation axis L-1 of the lever L are slidable with respect to the bevel gears 2 and 3, the two prisms J-1 and L-2 are In order to avoid meeting, it is desirable that the bevel gears 2 and 3 are bevel gears.
[0018]
In the drainage mechanism D of the present invention configured as described above, when the handle H provided on the front portion of the tank T is operated, one of the bevel gears 3 in the deflection transmission means K is rotated, and this is interlocked with this. Since the one bevel gear 2 rotates, the lever L disposed substantially parallel to the width direction of the tank T rotates. As a result, the drain valve device F is opened through the linkage means R such as a ball chain attached to the tip of the lever L with an appropriate connector 16, and drainage of the washing water is started.
[0019]
In the present invention, since the tip end of the lever L can be arranged at a position immediately above or near the drain valve device F, the linking means R can be brought into a substantially vertical state, and therefore the amount of rotation of the lever L can be increased. It is possible to accurately reflect the pull amount of the linkage means R. Therefore, for example, if a means 6 for limiting the amount of rotation of the bevel gears 2 and 3 is provided in the direction change transmission means K due to the difference in the rotation direction of the handle H and the lever L, depending on the rotation direction of the handle H. The amount of drainage of the washing water can be changed reliably by varying the amount of opening of the drain valve device F. That is, in the case where the operation handle is provided on the front face of the tank, the amount of washing water can be reliably switched.

Here, an example of the drain valve device F1 to which the drainage mechanism D according to the present invention is applied will be briefly described with reference to FIGS. The drain valve device F1 is provided, for example, at the bottom of a flush water tank for flush toilets, and includes the fixture 22, the ball valve 26, and the switching valve member 60 as main components. The fixing bracket 22 has a cylindrical shape that is attached to the bottom of the tank via a packing 23 and a tightening nut 24, and a lower end portion serves as a drain port 21. Inside, a guide piece 22b and a valve seat guide 50 are provided, and a dish-shaped valve seat portion 22a is formed on the upper end side. In addition, an overflow pipe 25 is erected on the fixing bracket 22 in a continuous manner.
[0021]
The ball valve 26 seated on the valve seat portion 22 a of the fixing fitting 22 is fitted with the engaging piece 26 b at the upper end of the connecting projection 26 a projecting from the upper surface thereof into the engaging projection 58 provided at the bottom of the water receiving cup 51. Thus, by fitting the retaining ring 59, the water receiving cup 51 is detachably connected. Further, a guide rod 27 is suspended from the lower surface of the top, and the guide rod 27 is inserted through a guide piece 22 b provided in the fixing bracket 22 and a guide hole 50 a of the valve seat guide 50.
[0022]
The water receiving cup 51 is provided with a connecting portion 52 and a guide cylinder 53 on its side surface, and the guide cylinder 53 is externally fitted to the overflow pipe 55 so as to be movable up and down. A stopper member 66 is fitted on the upper end of the overflow pipe 55. An inclined portion 54 is formed on the bottom surface portion 51 a of the water receiving cup 51 at a position eccentric from the center, and a rectangular outflow hole 55 is formed in the inclined portion 54. Reference numeral 56 denotes a contact stopper piece. On the upper edge of the water receiving cup 51, a pair of rising pieces 57 having a shaft hole 57a are erected so as to face each other, and the rotating shaft 61 of the switching valve member 60 is supported by the shaft hole 57a.
[0023]
In the switching valve member 60, a guide cylinder portion 62 is suspended from the center portion of the rotation shaft 61, and a spindle 63 penetrating through the guide cylinder portion 62 and slidable up and down is always urged downward by a spring SP. It has been incorporated in the state. A rectangular valve body 64 is provided at the lower end of the spindle 63, and a chain hook 65 for locking the ball chain R is provided at the upper end.
[0024]
The switching valve member 60 is tiltable within the water receiving cup 51 with the rotation shaft 61 as a fulcrum, and the tilting direction is set to the front-rear direction of the tank. When the ball chain R is pulled toward the X side (rear side of the tank) in FIG. 10, it tilts like a virtual line (two-dot chain line) and maintains the outflow hole 55 open. It becomes discharge. On the other hand, when the ball chain R is pulled to the Y side (front of the tank) in FIG. Since it maintains, it will be in the state where water accumulated in the water receiving cup 51. As a result, since the descending speed of the ball valve 26 is increased by the weight of the water stored in the water receiving cup 51, the drainage time is shortened and a small amount of washing water is discharged.
[0025]
Thus, the above-described drain valve device F1 needs to move the switching valve member 60 in the front-rear direction of the tank in order to switch the amount of drainage. However, by applying the present invention, the drain valve device F1 can be operated even when an operation handle is provided in front of the tank.
[0026]
By the way, the embodiment of the present invention is not limited to the above. For example, the direction change transmission means K can be configured such that, in addition to the bevel gear, the rotation axis J of the handle H and the rotation axis L-1 of the lever L are connected by a coil spring. In addition, this invention does not prevent changing suitably according to the condition of implementation.
[0027]
【The invention's effect】
According to the drainage mechanism according to the present invention, since the tip of the lever can be positioned immediately above or near the drainage valve device, the linking means for connecting the lever and the drainage valve device can be in a substantially vertical state. Therefore, the change in the amount of rotation of the lever can be accurately reflected in the pulling amount of the linkage means, so that the washing water amount can be reliably switched between large and small.
[0028]
In addition, by operating the handle attached to the front part of the tank, the lever arranged almost parallel to the width direction of the tank can be rotated in the front-rear direction of the tank, so that the linking means is pulled in the front-rear direction of the tank. Therefore, the conventional drain valve device of the kind necessary for the opening / closing operation can be used as it is.
