図9〜図12は特許文献1に記載された便器洗浄タンク装置を示している。
この便器洗浄タンク装置100は、タンク本体101内部おける底面部に洗浄水を便器へ給水する排水弁3を設けると共に、同タンク本体101周壁の上部には上記排水弁3を開弁させる操作ハンドル104と、便器洗浄を行なう度に給水源から供給される水をタンク本体内の給水レベルまで補給するボールタップ給水栓102を設けてある。タンク本体101と便器とを連絡する給水管112の上端口はタンク本体101底面の開口に対して嵌挿してあり、その給水管112の上端口が排水口132として構成されている。上記排水口132は排水弁103の弁口を構成するものであり、タンク本体101内の底面において上方へ向けて開口し、該排水口132に上方から排水弁体131が着座している。
9 to 12 show a toilet bowl cleaning tank device described in Patent Document 1. FIG.
This toilet bowl cleaning tank apparatus 100 is provided with a drain valve 3 for supplying cleaning water to the toilet bowl on the bottom surface inside the tank body 101, and an operation handle 104 for opening the drain valve 3 on the upper peripheral wall of the tank body 101. In addition, a ball tap faucet 102 is provided for replenishing water supplied from a water supply source to a water supply level in the tank body every time toilet cleaning is performed. The upper end port of the water supply pipe 112 that connects the tank main body 101 and the toilet bowl is fitted into the opening on the bottom surface of the tank main body 101, and the upper end port of the water supply pipe 112 is configured as a drain outlet 132. The drain port 132 constitutes the valve port of the drain valve 103, and opens upward on the bottom surface in the tank body 101, and the drain valve body 131 is seated on the drain port 132 from above.

円板状の排水弁体131は、オーバーフロー管115の下端に取り付け固定され、その中心部にはオーバーフロー管115を流れ落ちてくる水を排水口132に通過させる孔131aを穿設してある。オーバーフロー管115は後述する制御容器105の中心部を貫通し、制御容器105に支持される形で上下摺動自在に支持されている。制御容器105は上面を開口させた平面略D型の容器であり、脚114を介してタンク本体101底面に取り付け支持することにより、タンク本体101内における底面から幾分上の位置に設置してある。また、制御容器105の中心部には中筒部105aを垂直に貫通させた状態で設け、該中筒部105a内部に沿って前記オーバーフロー管115を摺動自在に嵌挿し、該オーバーフロー管115の上昇端において管下端に設けた排水弁体131が制御容器105の底面に当接させることにより、後述する浮き子体107による浮上上限を定めてある。   The disc-shaped drain valve body 131 is attached and fixed to the lower end of the overflow pipe 115, and a hole 131a through which water flowing down the overflow pipe 115 passes through the drain port 132 is formed in the center thereof. The overflow pipe 115 passes through a center portion of the control container 105 described later, and is supported by the control container 105 so as to be vertically slidable. The control container 105 is a substantially flat D-shaped container having an open top surface, and is installed at a position slightly above the bottom surface in the tank body 101 by being attached to and supported by the bottom surface of the tank body 101 via the legs 114. is there. In addition, the middle tube portion 105a is vertically penetrated through the central portion of the control vessel 105, and the overflow pipe 115 is slidably inserted along the inside of the middle tube portion 105a. A drainage valve body 131 provided at the lower end of the pipe is brought into contact with the bottom surface of the control container 105 at the rising end, thereby setting an upper limit of levitation by the float body 107 described later.

前記オーバーフロー管115の上部外周からは中筒部105aを避けて制御容器105内へ延びる2本の連結部材113を突出してあり、これら連結部材113の下端に各々中空状の浮き子体107を取り付け固定してある。浮き子体107はオーバーフロー管115と排水弁体131とを浮上させるだけの浮力を生じる中空体であり、上記制御容器105の内部に収納され、連結部材113を介して一体化するオーバーフロー管115の上下動に伴って、容器5内において上昇、降下するように支持されている。   From the upper outer periphery of the overflow pipe 115, two connecting members 113 extending into the control container 105 avoiding the middle cylinder portion 105 a are protruded, and hollow floats 107 are respectively attached to the lower ends of these connecting members 113. It is fixed. The float body 107 is a hollow body that generates a buoyancy sufficient to float the overflow pipe 115 and the drain valve body 131. The float body 107 is housed in the control container 105 and integrated with the connecting pipe 113. Along with the vertical movement, the container 5 is supported so as to rise and fall.

上記制御容器105の側壁の平面部105bには流出口108を開口し、この流出口108の外側に開閉弁蓋109が設けてある。流出口108は小洗浄時において制御容器105内の水を短時間の間に流出させる為のものであり、タンク本体101内における底面から所定の高さ、即ち小洗浄時におけるタンク本体内水位の低限のレベルに合わせて開口してある。一方、上記流出口108に設ける開閉弁蓋109は、図9及び図11によって示す如く板状に形成し、制御容器105側壁に開口した流出口108に外側からあてがう形で設けてある。弁蓋109の両側辺部には下へ向けて垂直に延出するガイドシャフト191を設けてあり、このガイドシャフト191を流出口108の両側辺部に沿って垂直に設けた摺動孔192に対して上方から摺動自在に挿嵌することにより、上下にスライドして流出口108を開閉自在に閉鎖している。通常、上記した開閉弁蓋109は自重により閉弁状態を維持しているが、上部に連結した連結部材111が操作ハンドル104の回動操作により引き上げられることにより上昇して開弁し、上記連結部材111が弛むことにより自重により再び降下して流出口108を閉鎖する。   An outlet 108 is opened in the flat portion 105 b on the side wall of the control container 105, and an open / close valve lid 109 is provided outside the outlet 108. The outlet 108 is used to allow the water in the control container 105 to flow out in a short time during the small cleaning, and is a predetermined height from the bottom surface in the tank main body 101, that is, the water level in the tank main body during the small cleaning. Opened to a low level. On the other hand, the on-off valve lid 109 provided at the outlet 108 is formed in a plate shape as shown in FIGS. 9 and 11 and is provided so as to be applied to the outlet 108 opened on the side wall of the control container 105 from the outside. Guide shafts 191 that extend vertically downward are provided on both sides of the valve lid 109, and the guide shafts 191 are provided in sliding holes 192 that are provided vertically along both sides of the outlet 108. On the other hand, the outlet 108 is slidably inserted from above to slide up and down to close the outlet 108 so as to be opened and closed. Normally, the above-described on-off valve lid 109 maintains a closed state by its own weight, but when the connecting member 111 connected to the upper part is pulled up by the turning operation of the operation handle 104, the valve is raised and opened. When the member 111 is loosened, it is lowered again by its own weight and closes the outlet 108.

上記ガイドシャフト191は開閉弁蓋109が降下する時に摺動孔192の内部に嵌挿されるように摺動するが、上記摺動孔192の下端口は小径に絞ってあり、ガイドシャフト191が摺動孔192の内部を降下するのに伴って摺動孔192内を満たす水がその小径孔193を介して外部へ噴出し、その際に適度な抵抗が生じ、開閉弁蓋109の降下が遅延させるようになっている。尚、上記した抵抗は、小径孔93を設けずに、ガイドシャフト191と摺動孔192との間に適度なクリアランスを設け、このクリアランスを介して摺動孔192内と外部との間の水の出入りを行なうように構成しても発生させることができる。よって操作ハンドル104の操作に開閉弁蓋109が引き上げられ、その後、開閉弁蓋109が自重により閉弁する際に、ガイドシャフト191の降下により摺動孔192の内部から小径孔193を介して噴出する。この時、ガイドシャフト191に必要な抵抗が生じ、この抵抗によって開閉弁蓋109がゆっくりと時間をかけて降下するようになっている。上記制御容器105の底面には小通孔116が穿設してある。この小通孔116は制御容器105内の水を少量ずつ排水することにより容器105内の浮き子体107を時間をかけて降下させるためのものであり、容器105内を満たす水が容器下部の浮き子体7降下位置に低下するまで所定の時間、例えばタンク本体内洗浄水の排水開始から排水が完全に終了するまでの時間をかけて流出し得る直径に設定してある。   The guide shaft 191 slides so as to be inserted into the slide hole 192 when the on-off valve lid 109 is lowered. The lower end of the slide hole 192 is narrowed to a small diameter, and the guide shaft 191 is slid. As the inside of the moving hole 192 descends, the water filling the sliding hole 192 is ejected to the outside through the small diameter hole 193, and an appropriate resistance is generated at that time, and the lowering of the on-off valve lid 109 is delayed. It is supposed to let you. The above-described resistance is obtained by providing an appropriate clearance between the guide shaft 191 and the sliding hole 192 without providing the small-diameter hole 93, and the water between the inside of the sliding hole 192 and the outside through this clearance. It can be generated even if it is configured to enter and exit. Therefore, the opening / closing valve lid 109 is pulled up by the operation of the operation handle 104, and then, when the opening / closing valve lid 109 is closed by its own weight, the guide shaft 191 is lowered to eject from the inside of the sliding hole 192 through the small diameter hole 193. To do. At this time, a necessary resistance is generated in the guide shaft 191, and the opening / closing valve cover 109 slowly descends over time due to this resistance. A small through hole 116 is formed in the bottom surface of the control container 105. This small through hole 116 is for draining the water in the control container 105 little by little to lower the float 107 in the container 105 over time, and the water filling the container 105 is in the lower part of the container. It is set to a diameter that can flow out over a predetermined time until the float body 7 is lowered to the lowering position, for example, the time from the start of draining of the washing water in the tank body until the drainage is completely completed.

タンク本体101周壁の上部に設けられる操作ハンドル104はタンク本体101内へ向けて水平に延びる回動軸141と下向きに突出するレバー142とを備え、上記回動軸141をタンク本体101周壁に嵌着した支持筒111に外側から嵌挿することにより、左右に所定角度ずつ回動するように支持してある。また、操作ハンドル104は大洗浄と小洗浄とに対応して回動方向が定めてあり、レバー142が下向きになる位置を中立として、ハンドル104を左に回動させると大洗浄が行なわれ、右に回動させると小洗浄が行なわれるようになっている。   The operation handle 104 provided at the upper part of the peripheral wall of the tank main body 101 includes a rotation shaft 141 extending horizontally into the tank main body 101 and a lever 142 protruding downward, and the rotation shaft 141 is fitted to the peripheral wall of the tank main body 101. By being inserted into the worn support cylinder 111 from the outside, it is supported so as to rotate by a predetermined angle from side to side. Further, the rotation direction of the operation handle 104 is determined in accordance with the large washing and the small washing. When the handle 104 is turned to the left with the position where the lever 142 faces downward, the large washing is performed. When it is turned to the right, small washing is performed.

タンク本体101内に水平に延出する回動軸141の外周には回動管161を嵌着し、この回動管161に排水弁体131を引き上げる腕片162と開閉弁蓋109を引き上げる引き上げ腕片163とを各々下へ向けて取り付けてある。腕片162には鎖等からなる連結部材110を垂下し、該連結部材110の下端を弛みの無い状態でオーバーフロー管115の上端に接続してある。また、引き上げ腕片163は回動管161外周に固定される固定片164と該固定片164中間部に回転軸165を介して軸支される回動片166とから構成され、上記固定片の先端部一側辺部に係止片167を屈曲形成してある。そして、上記した回動片166の先端からは連結部材111を垂下させ、その連結部材111の下端を前記した開閉弁蓋109の上部に幾分弛ませた状態で接続してある。よって、操作ハンドル104を大側に回動させると、図12(b)にて示すように一方へ向けて所定角度回動した固定片164の回転軸165から回動片166が垂下する形で連結部材111が小さく引き上げられる。尚、この引き上げでは引き上げストロークが小さい為に連結部材111の弛みがとれるだけで開閉弁蓋109は閉状態を維持している。また、操作ハンドル104を小側に回動させると、固定片164が所定角度回動する共に係止片167に係止された回動片166が固定片164を延長する形で回動され、これより連結部材111が大きなストロークで引き上げられて開閉弁蓋109が開弁する。   A rotary pipe 161 is fitted on the outer periphery of a rotary shaft 141 that extends horizontally into the tank body 101, and an arm piece 162 that pulls up the drain valve body 131 and a pull-up valve that raises the on-off valve lid 109. The arm pieces 163 are attached facing downward. A connecting member 110 made of a chain or the like is suspended from the arm piece 162, and the lower end of the connecting member 110 is connected to the upper end of the overflow pipe 115 without slack. The lifting arm piece 163 includes a fixed piece 164 fixed to the outer periphery of the rotary tube 161, and a rotary piece 166 supported on the intermediate portion of the fixed piece 164 via a rotary shaft 165. A locking piece 167 is bent at one side of the tip. The connecting member 111 is suspended from the tip of the rotating piece 166, and the lower end of the connecting member 111 is connected to the upper part of the opening / closing valve lid 109 in a somewhat slackened state. Therefore, when the operation handle 104 is rotated to the large side, the rotating piece 166 hangs down from the rotating shaft 165 of the fixed piece 164 rotated by a predetermined angle toward one side as shown in FIG. The connecting member 111 is pulled up small. In this pulling up, since the pulling stroke is small, the opening / closing valve lid 109 is kept closed only by loosening the connecting member 111. Further, when the operation handle 104 is rotated to the small side, the fixed piece 164 is rotated by a predetermined angle and the rotary piece 166 locked to the locking piece 167 is rotated so as to extend the fixed piece 164. Accordingly, the connecting member 111 is pulled up with a large stroke, and the on-off valve lid 109 is opened.

以上の手段により、小洗浄時、操作ハンドルの回動により連結部材を介して開閉弁蓋が大きく引き上げられ、制御容器の流出口が開口する。反対に大洗浄時においては、連結部材による引き上げ量が小さくなり、開閉弁蓋は閉状態を維持する。また、小洗浄時において引き上げられた開閉弁蓋は、自重により降下するが、降下遅延機構によりその降下が所定時間遅延される。従って、上記遅延時間の間、開閉弁蓋が開かれることになり、これにより流出口から制御容器内の水が急速に流出して排水弁体の閉弁が早められる。この結果、タンク内に残留洗浄水が発生し、当該残留水分、便器に対する給水量が削減されたことになる。   By the above means, at the time of small cleaning, the opening / closing valve lid is largely pulled up through the connecting member by the rotation of the operation handle, and the outlet of the control container is opened. On the other hand, at the time of large cleaning, the amount of pulling up by the connecting member is small, and the on-off valve lid is kept closed. Further, the open / close valve lid that is lifted during the small washing is lowered by its own weight, but the lowering is delayed for a predetermined time by the lowering delay mechanism. Therefore, during the delay time, the on-off valve lid is opened, whereby the water in the control container quickly flows out from the outlet and the drain valve body is closed earlier. As a result, residual washing water is generated in the tank, and the residual water and the amount of water supplied to the toilet are reduced.

上記した従来の便器洗浄タンク装置は、排水弁体131の開弁時間制御を、制御容器105の側壁の平面部105bに開口した流出口108を弁蓋109の遅延閉止により、制御筒105内の水の流出速度を可変させることにより行っているが、弁蓋109の遅延閉止を、弁蓋109の側辺部に下へ向けて垂直に延出するガイドシャフト191と、流出口108の両側辺部に沿って垂直に設けた摺動孔192とのクリアランスから漏れる水を利用したダンパー機構により構成しているため、前記クリアランスにタンク本体101内に存在する微小なゴミ、洗浄水より析出したスケール等の噛み込みにより、弁蓋109の開弁不良が発生した。また、弁蓋109を開弁させる際にも前記ダンパー効果が機能するため、弁蓋109の開弁に過大な開弁荷重が必要となり、操作ハンドル104の操作力の増大、連結部材111の切断等の不具合がした。   The above-described conventional toilet flushing tank device controls the valve opening time of the drain valve body 131 by delaying the valve lid 109 at the outlet 108 opened in the flat portion 105b of the side wall of the control container 105. Although the water outflow speed is varied, the valve lid 109 is delayed closed by a guide shaft 191 extending vertically downward on the side of the valve lid 109 and both sides of the outlet 108. Since it is configured by a damper mechanism that uses water leaking from the clearance with the sliding hole 192 provided vertically along the portion, the scale deposits from the minute dust and cleaning water present in the tank body 101 in the clearance. As a result, the valve lid 109 failed to open. Further, the damper effect also functions when the valve lid 109 is opened. Therefore, an excessive valve opening load is required to open the valve lid 109, the operating force of the operation handle 104 is increased, and the connecting member 111 is disconnected. There were problems such as.

本発明の目的は、上記のように如き大洗浄と小洗浄の切り替え機構を具備する便器洗浄タンク装置に対して、軽い力で制御筒に設けられた流出口を開閉可能として、確実に大小洗浄を切替動作させることができる便器洗浄タンク装置を提供することを目的とする。   The object of the present invention is to reliably open and close the large and small washing by opening and closing the outlet provided in the control cylinder with a light force with respect to the toilet flushing tank apparatus having the switching mechanism between the large washing and the small washing as described above. An object of the present invention is to provide a toilet bowl cleaning tank device capable of switching the operation of the toilet bowl.

上記目的を解決するために本発明の請求項1の便器洗浄タンク装置は、タンク本体内の底部に便器へ連絡する排水口を上向きに開口すると共に、この排水口により構成した弁口に対して排水弁体を上方から開閉自在に着座させて排水弁を構成し、上記排水弁体に同弁体を浮上させる直動弁用フロートを取り付け、該直動弁用フロートをタンク本体内底部から間隔を置いて所定の高さに設置した制御筒の内部に昇降自在な状態で収容し、上記制御筒の上部を開口すると共に、この制御筒下部に遅延閉止用小通孔を開設し、また、この制御筒の下部に前記排水口よりも下流側と連通した大通孔を設け、前記タンク本体上部に設けた操作手段により引き上げられる2つのの連結部材の内、一方を上記排水弁体に、他方を制御筒の大通孔を開閉可能に支持される小洗浄用パイロット弁に各々連結し、上記操作手段により小洗浄が選択されると前記2つの連結部材をを引き上げて前記排水弁体及び前記小洗浄用パイロット弁を開動させ、上記操作手段により大洗浄が選択されると前記一方の引き上げ手段のみを引き上げて前記排水弁体を開状態として前記小洗浄用パイロット弁を閉状態とする引き上げ部材作動機構を具備してなる構成としたものである。   In order to solve the above-mentioned object, the toilet flushing tank apparatus according to claim 1 of the present invention opens a drainage port that communicates with the toilet bowl at the bottom of the tank body upward, and a valve port constituted by the drainage port. The drain valve body is configured to be openable and closable from above, and a drain valve is mounted on the drain valve body. A direct valve float is attached to the drain valve body, and the float is spaced from the inner bottom of the tank body. Is placed in a control cylinder installed at a predetermined height so that it can be moved up and down, and the upper part of the control cylinder is opened, and a small passage for delay closing is opened at the lower part of the control cylinder. A large through hole communicating with the downstream side of the drain port is provided in the lower part of the control cylinder, and one of the two connecting members pulled up by the operating means provided in the upper part of the tank body is used as the drain valve body, and the other The large through hole of the control cylinder can be opened and closed When the small cleaning is selected by the operation means, the two connecting members are pulled up to open the drain valve body and the small cleaning pilot valve. When a large cleaning is selected by the means, only the one lifting means is lifted to open the drain valve body and to close the small cleaning pilot valve. It is.

また、請求項2の前記便器洗浄タンク装置において、前記制御筒に設けられた前記小洗浄用パイロット弁を上下に摺動可能に格納する格納部と、前記小洗浄用パイロット弁の外周面又は前記格納部の内壁面から他方に向かって突設形成されたリブと、を備える構成としたものである。   Further, in the toilet flushing tank device according to claim 2, a storage portion for slidably storing the small cleaning pilot valve provided in the control cylinder, and an outer peripheral surface of the small cleaning pilot valve or the And a rib projecting from the inner wall surface of the storage portion toward the other.

また、請求項3の前記便器洗浄タンク装置において、前記格納部の上部に、この格納部よりも内径が小さい円筒部材を設け、この円筒部材の中を前記小洗浄用パイロット弁と連結された連結部材が挿通する構成としたものである。   The toilet bowl cleaning tank device according to claim 3, wherein a cylindrical member having an inner diameter smaller than that of the storage portion is provided at an upper portion of the storage portion, and the cylindrical member is connected to the small cleaning pilot valve. The member is configured to be inserted.

また、請求項4の円筒部材は、タンク上方に向かって徐拡大する構成としたものである。   Moreover, the cylindrical member of Claim 4 is set as the structure which expands gradually toward a tank upper direction.

本発明は以上説明したように、操作ハンドルの回動方向を大側と小側とに選択することにより、制御筒の下部に前記排水口よりも下流側と連通した大通孔を小洗浄用パイロット弁により閉口若しくは開口した状態で排水弁からの排水を開始し、制御容器内における水位の低下時間を変化させることで、排水弁の閉弁のタイミングを遅い場合(大洗浄)と、早い場合(小洗浄)とに制御し、タンク本体内から便器に対して行われる洗浄水排水量の大小を選択的に切り替えるように構成したものであるから、従来の便器洗浄タンク装置のように、制御筒から水の流出制御を行う弁蓋にダンパー機構を有する必要が無くなり、軽い力で制御筒に設けられた大通孔を開閉可能として、確実に大小洗浄を切替動作させることができる。   As described above, according to the present invention, by selecting the rotation direction of the operation handle from the large side and the small side, the large through hole communicating with the downstream side from the drain port is formed in the lower portion of the control cylinder. By starting drainage from the drainage valve with the valve closed or open, and changing the water level lowering time in the control container, the timing of closing the drainage valve is slow (large washing) and early ( Small wash), and is configured to selectively switch the amount of washing water drainage performed on the toilet from within the tank body. It is no longer necessary to have a damper mechanism on the valve lid that controls the outflow of water, and the large through hole provided in the control cylinder can be opened and closed with a light force, so that the large and small washing can be switched reliably.

以下に図面を参照して本発明をより具体的に説明する。
図1は、本発明を実施した便器洗浄タンク装置を一部切欠して示す正面図である。この図1にて示す便器洗浄タンク装置aは便器(図示せず)の上方部に設置するものであり、陶器製のタンク本体1内部における底面部に洗浄水を便器へ給水する排水弁3を開弁させる操作ハンドル8、便器洗浄を行う度に給水源から供給される水をタンク本体内の給水レベルまで補給するボールタップ給水栓2を設けてある。タンク本体1と便器とを連絡する給水管12の上端口はタンク本体1底面の開口に対して嵌挿してあり、その給水管12の上端口が排水口32として構成されている。上記排水口32は排水弁3の弁口を構成するものであり、タンク本体1内の底面において上方へ向けて開口し、排水口32に上方から排水弁体31が着座している。
Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a front view of a toilet bowl cleaning tank apparatus according to the present invention, partially cut away. The toilet bowl cleaning tank device a shown in FIG. 1 is installed in the upper part of a toilet bowl (not shown), and a drain valve 3 for supplying cleaning water to the toilet bowl is provided on the bottom of the tank body 1 made of ceramics. An operation handle 8 for opening the valve and a ball tap faucet 2 for replenishing the water supplied from the water supply source to the water supply level in the tank body each time the toilet bowl is cleaned are provided. The upper end port of the water supply pipe 12 that connects the tank main body 1 and the toilet bowl is fitted into the opening on the bottom surface of the tank main body 1, and the upper end port of the water supply pipe 12 is configured as a drain port 32. The drain port 32 constitutes the valve port of the drain valve 3, opens upward on the bottom surface in the tank body 1, and the drain valve body 31 is seated on the drain port 32 from above.

円板状の排水弁体31は、オーバーフロー管15の下端に取り付け固定され、その中心部にはオーバーフロー管15を流れ落ちてくる水を排水口32に通過させる孔31aを穿設してある。オーバーフロー管15は後述する制御筒5の中心部を貫通し、制御筒5に支持される形で上下摺動自在に支持されている。制御筒5は上面を開口させた円筒型の容器であり、給水管12に勘合取り付けすることにより、タンク本体1内における底面から幾分上の位置に設置してある。尚、上記した制御筒5は円筒型以外の形状であってもよい。また、制御筒5の中心部には中筒部5aを垂直に貫通させた状態で設け、中筒部5a内部に沿ってオーバーフロー管15の上端において下端に設けた排水弁体31が制御筒5の底面に当接させることにより、後述する本発明における直動弁用フロートとしての浮き子体7による浮上上限を定めてある。   The disc-shaped drain valve body 31 is attached and fixed to the lower end of the overflow pipe 15, and a hole 31 a through which water flowing down the overflow pipe 15 passes through the drain port 32 is formed at the center thereof. The overflow pipe 15 passes through the center portion of the control cylinder 5 described later, and is supported by the control cylinder 5 so as to be vertically slidable. The control cylinder 5 is a cylindrical container having an upper surface opened, and is installed at a position somewhat above the bottom surface in the tank main body 1 by fitting to the water supply pipe 12. The control cylinder 5 described above may have a shape other than a cylindrical shape. Further, a drain valve body 31 provided at the lower end at the upper end of the overflow pipe 15 along the inside of the middle cylinder portion 5a is provided in the central portion of the control cylinder 5 with the middle cylinder portion 5a penetrating vertically. The upper limit of the levitation by the float body 7 as a direct acting valve float in the present invention to be described later is determined.

前記オーバーフロー管15の上方外周面にはフランジ部15aを形成している。浮き子体7は円筒部7aと円筒部7a下端に下方開口した浮き子7bにて形成している。円筒部7a上部にはフランジ部15a上面に当接させる段部7cを形成し、オーバーフロー管15を浮き子体7の円筒部7aに浮き子体7下方より挿入し、フランジ部15a上面と段部7cを当接させ、オーバーフロー管15上部に止め部材55を装着することにより、オーバーフロー管15と浮き子体7を一体化した。浮き子7bはオーバーフロー管15と排水弁体31と止め部材55を浮上させるだけの浮力を生じる下方開口容器であり、上記制御筒5の内部に収納され、該オーバーフロー管15の上下動に伴って、制御筒5内において上昇、下降するように支持されている。なお、浮き子7bの形態は下方開口容器に限るものではなく、円筒型中空体でもよい。   A flange portion 15 a is formed on the upper outer peripheral surface of the overflow pipe 15. The float 7 is formed by a cylinder 7a and a float 7b opened downward at the lower end of the cylinder 7a. A step portion 7c is formed on the upper portion of the cylindrical portion 7a so as to contact the upper surface of the flange portion 15a, and the overflow pipe 15 is inserted into the cylindrical portion 7a of the float body 7 from below the float body 7 so The overflow pipe 15 and the float body 7 were integrated by bringing 7c into contact and mounting the stop member 55 on the upper part of the overflow pipe 15. The float 7b is a lower opening container that generates buoyancy sufficient to float the overflow pipe 15, the drain valve body 31, and the stopper member 55. The float 7b is housed inside the control cylinder 5 and moves upward and downward with the overflow pipe 15. The control cylinder 5 is supported so as to rise and fall. In addition, the form of the float 7b is not restricted to a downward opening container, A cylindrical hollow body may be sufficient.

制御筒5の底面には小通孔51が穿設してある。この小通孔51は制御筒5内の水を少量ずつ排水することにより制御筒5内の浮き子体7を時間をかけて下降させるためのものであり、制御筒5内を満たす水が制御筒下部の浮き子体7下降位置に低下するまでの所定の時間、例えばタンク本体1内洗浄水の排水開始から排水が完全に終了するまでの時間をかけて流出し得る直径に設定してある。また、制御筒5の下部には前記小通孔51よりも開口面積が大きな大通孔52を開設し、該大通孔52と連通する通水筒53が制御筒5の下方からタンク本体1底面へ突出している。給水管12には給水管12上端口よりも下流側と連通した流出口34を設け、該流出口34と前記通水筒53が連結管6により連通している。大通孔52の上端には小洗浄用パイロット弁4が配設されている。該小洗浄用パイロット弁4はシール部材41とフロート42より構成され、前記シール部材41はフロート42下端に配設されおり、前記シール部材41下面と大通孔52上部が当接することにより大通孔52を閉塞している。   A small through hole 51 is formed in the bottom surface of the control cylinder 5. This small through hole 51 is for draining the water in the control cylinder 5 little by little to lower the float 7 in the control cylinder 5 over time, and the water filling the control cylinder 5 is controlled. It is set to a diameter that can flow out over a predetermined time until the float body 7 is lowered to the lowering position of the lower part of the cylinder, for example, from the start of drainage of the wash water in the tank body 1 until the drainage is completely completed. . In addition, a large through hole 52 having an opening area larger than that of the small through hole 51 is opened at the lower portion of the control cylinder 5, and a water through cylinder 53 communicating with the large through hole 52 projects from the bottom of the control cylinder 5 to the bottom surface of the tank body 1. ing. The water supply pipe 12 is provided with an outlet 34 communicating with the downstream side of the upper end of the water supply pipe 12, and the outlet 34 and the water pipe 53 are communicated with each other through the connecting pipe 6. A small cleaning pilot valve 4 is disposed at the upper end of the large through hole 52. The pilot valve 4 for small cleaning is composed of a seal member 41 and a float 42. The seal member 41 is disposed at the lower end of the float 42, and the large through hole 52 is formed by contacting the bottom surface of the seal member 41 with the upper portion of the large through hole 52. Is blocked.

タンク本体1内において、洗浄水貯水時における小洗浄用パイロット弁4による大通孔52の閉塞原理を説明する。まず、排水弁体31により排水口32閉塞時、小洗浄用パイロット弁4の下面のシール位置より内側領域は、給水管12の流出口34と制御筒5下部の通水筒53が連結管6により連通しているため、大気圧が作用している。また小洗浄用パイロット弁4の上面部はタンク本体1内の給水レベルにより作用する水頭圧が作用している。このため、小洗浄用パイロット弁4にはタンク下方向にフロート42自重F1、シール部材41自重F2、小洗浄用パイロット弁上面に作用する水頭圧とパイロット弁下面に作用する大気圧の差圧により発生する荷重F3が作用し、タンク上方向にはフロート42により発生する浮力F4が発生し、(F1+F2+F3)>F4となるフロート容量に設定することにより、大通孔52をシール部材により閉塞する。   The principle of closing the large through hole 52 by the small cleaning pilot valve 4 when storing the cleaning water in the tank body 1 will be described. First, when the drain port 31 is closed by the drain valve body 31, the outlet 34 of the water supply pipe 12 and the water pipe 53 at the bottom of the control cylinder 5 are connected by the connecting pipe 6 in the inner area from the seal position on the lower surface of the pilot valve 4 for small washing. Because it communicates, atmospheric pressure is acting. Further, the water head pressure acting on the upper surface portion of the small cleaning pilot valve 4 is applied depending on the water supply level in the tank body 1. For this reason, the small cleaning pilot valve 4 has a float 42 self-weight F1, a seal member 41 self-weight F2, and a pressure difference between the head pressure acting on the top surface of the small cleaning pilot valve and the atmospheric pressure acting on the bottom surface of the pilot valve. The generated load F3 acts, and the buoyancy F4 generated by the float 42 is generated in the upward direction of the tank. By setting the float capacity such that (F1 + F2 + F3)> F4, the large through hole 52 is closed by the seal member.

次に本発明の操作手段としての操作ハンドル8が大洗浄側へ回動し、オーバーフロー管15のみが引き上げられ排水口32が開口状態になった場合の、小洗浄用パイロット弁4による大通孔52の閉塞原理を説明する。排水口32が開口状態になることによりタンク本体1内の洗浄水が給水管12へ流入し、給水管12内部は洗浄水にて満たされるため、上記にて説明したF3は小洗浄用パイロット弁上面に作用する水頭圧とパイロット弁下面に作用する静圧の差圧により発生する荷重へと変化するが、給水管12内を流れる水の流速により前記水頭圧よりもパイロット弁下面に作用する静圧の方が小さい状態となる。そのためF3は依然としてタンク下方向へ作用する荷重となるため、小洗浄用パイロット弁4は大通孔52に負勢され、大通孔52を閉塞した状態を維持する。   Next, when the operation handle 8 as the operation means of the present invention is rotated to the large washing side, only the overflow pipe 15 is pulled up and the drain port 32 is opened, the large through hole 52 by the small washing pilot valve 4 is provided. The occlusion principle will be described. When the drain port 32 is opened, the cleaning water in the tank body 1 flows into the water supply pipe 12, and the inside of the water supply pipe 12 is filled with the cleaning water. Therefore, F3 described above is a pilot valve for small cleaning. Although the load changes due to the differential pressure between the water head pressure acting on the upper surface and the static pressure acting on the lower surface of the pilot valve, the static velocity acting on the lower surface of the pilot valve rather than the water head pressure due to the flow rate of water flowing in the water supply pipe 12. The pressure becomes smaller. Therefore, since F3 is still a load that acts downward in the tank, the small cleaning pilot valve 4 is biased toward the large through hole 52 and maintains the large through hole 52 closed.

タンク本体1周壁の上部に設けられる操作ハンドル8はタンク本体1内へ向けて水平に伸びる回動軸81と下向きに突出するレバー82とを備え、上記回動軸81をタンク本体1周壁に嵌着した支持筒83に外側から嵌挿することにより、左右に所定角度角度ずつ回動するように支持してある。また、操作ハンドル8は大洗浄と小洗浄とに対応して回動方向を定めてあり、レバー82が下向きになる位置を中心として、ハンドル82を左に回動させると大洗浄が行われ、右に回動させると小洗浄が行われるようになっている。   The operation handle 8 provided at the upper part of the peripheral wall of the tank main body is provided with a rotating shaft 81 extending horizontally into the tank main body 1 and a lever 82 protruding downward, and the rotating shaft 81 is fitted to the peripheral wall of the tank main body 1. By being inserted into the worn support cylinder 83 from the outside, it is supported so as to rotate by a predetermined angle angle to the left and right. Further, the operation handle 8 has a rotation direction corresponding to the large washing and the small washing, and when the handle 82 is turned to the left around the position where the lever 82 faces downward, the large washing is performed. When it is turned to the right, small washing is performed.

タンク本体1内に水平に伸出する回動軸81の外周には、小洗浄用パイロット弁引き上げ部材91を挿入し、次にオーバーフロー管引き上げ部材92を嵌着している。オーバーフロー管引き上げ部材92はレバーを大洗浄側、小洗浄側のいずれの方向に回動させた場合にも、回動軸81の回動方向と連動して回動し、オーバーフロー管15を引き上げる。   A small cleaning pilot valve lifting member 91 is inserted on the outer periphery of the rotating shaft 81 extending horizontally into the tank body 1, and then an overflow pipe lifting member 92 is fitted. The overflow pipe lifting member 92 rotates in conjunction with the rotation direction of the rotary shaft 81 to lift the overflow pipe 15 when the lever is rotated in either the large washing side or the small washing side.

図2は、図1におけるII―II線における断面図であり、小洗浄用パイロット弁4と回動軸81との位置関係を示す断面図である。この図2にて小洗浄用パイロット弁引き上げ部材91の回動原理を説明する。図2(b)はハンドル82を操作していない中立位置である。この中立位置から図2(a)のようにハンドル82を小洗浄側へ回動した場合、回動軸81の外周に配設された跳ね上げリブ81aが小洗浄用パイロット弁引き上げ部材91の跳ね上げ面91aと当接し、該リブ81aにより該跳ね上げ面91aを介して小洗浄用パイロット弁引き上げ部材91を回動軸81の回動に同調して回動し、小洗浄用パイロット弁4はタンク上方へ引き上げられる。次に図2(c)のようにハンドル82を大洗浄側へ回動した場合、該リブ81aと小洗浄用パイロット弁引き上げ部材91間は、大洗浄側回動角度より大なる空走角αを設けているため、該リブ81aと小洗浄用パイロット弁引き上げ部材91の跳ね上げ面91aは当接せず、小洗浄用パイロット弁引き上げ部材91は自重により初期位置を保持したままであるため、小洗浄用パイロット弁4は制御筒5の大通孔52に当接された状態を維持する。   FIG. 2 is a cross-sectional view taken along the line II-II in FIG. 1 and is a cross-sectional view showing the positional relationship between the small cleaning pilot valve 4 and the rotating shaft 81. The principle of rotation of the small cleaning pilot valve lifting member 91 will be described with reference to FIG. FIG. 2B shows a neutral position where the handle 82 is not operated. When the handle 82 is rotated from the neutral position to the small washing side as shown in FIG. 2A, the flip-up rib 81 a disposed on the outer periphery of the rotation shaft 81 jumps the pilot valve lifting member 91 for small washing. The small washing pilot valve 4 is brought into contact with the raising surface 91a and is rotated by the rib 81a via the springing surface 91a in synchronization with the rotation of the rotary shaft 81. The tank is pulled up. Next, when the handle 82 is turned to the large washing side as shown in FIG. 2C, the idle running angle α larger than the large washing side turning angle is provided between the rib 81a and the small washing pilot valve lifting member 91. Therefore, the rib 81a and the spring-up surface 91a of the small cleaning pilot valve lifting member 91 are not in contact with each other, and the small cleaning pilot valve lifting member 91 maintains its initial position by its own weight. The small cleaning pilot valve 4 is kept in contact with the large through hole 52 of the control cylinder 5.

上記した如く構成した便器洗浄タンク装置aの作動説明をする。通常時、タンク本体1内はボールタップ給水栓2により行われる給水によって、タンク本体1内の上限水位(図1のWL)まで洗浄水が貯水されている。この状態において排水弁3は水頭圧により閉弁され、小洗浄用パイロット弁4も同様に水頭圧により閉弁されている。   The operation of the toilet flushing tank apparatus a configured as described above will be described. Normally, the wash water is stored in the tank main body 1 up to the upper limit water level (WL in FIG. 1) in the tank main body 1 by water supplied by the ball tap water tap 2. In this state, the drain valve 3 is closed by the water head pressure, and the small washing pilot valve 4 is similarly closed by the water head pressure.

大洗浄に際して、使用者が操作ハンドル8を大洗浄側に回動すると、オーバーフロー管跳ね上げ部材92が所定角度回動し、この回動により連結部材10及びオーバーフロー管15が引き上げられて排水弁体31が開弁する。この時点から、タンク本体1から便器に対する洗浄水の給水が開始される。また、一旦開弁した排水弁体31は浮き子体7による浮力により上昇して開弁状態を維持する。このとき、前記した小洗浄用パイロット弁4の作動原理により、該小洗浄用パイロット弁4は初期状態を維持される。   When the user rotates the operation handle 8 to the large cleaning side during the large cleaning, the overflow pipe jumping member 92 rotates by a predetermined angle, and the connecting member 10 and the overflow pipe 15 are pulled up by this rotation, and the drain valve body. 31 opens. From this time point, supply of the washing water from the tank body 1 to the toilet is started. Further, the drain valve body 31 once opened is raised by the buoyancy by the float body 7 to maintain the valve open state. At this time, the small cleaning pilot valve 4 is maintained in the initial state by the operating principle of the small cleaning pilot valve 4 described above.

洗浄水の排水に伴ってタンク本体1内水位が低下し、制御筒5上端の開口部まで下がると、タンク本体1内の洗浄水が制御筒5内に流れ込むことがなくなり、さらにタンク本体1内の洗浄水は排水口32から大量に排水され水位も急速に低下する。これと平行して制御筒5底面の小通孔51からも制御筒5内の水が流出し、浮き子体7も降下するが、小通孔51からの流出量が少ないために制御筒5内水位の低下は遅く、時間をかけてゆっくりと降下する。よって、上記した浮き子体7が制御筒5内下部まで降下し、排水弁体31が排水口32に着座するまでの間には、タンク本体1内の排水口32の上端(図1にDWL1で示す)より下となる部分を除く洗浄水は全て排水され、排水が完了している。即ち、大洗浄時においてはタンク本体1内の排水弁3を開いて排出可能な水が全て排水されることになる。排水弁3が閉弁した後は、タンク本体1内上部のボールタップ給水栓2から給水が行われ、タンク本体1内の上限水位まで洗浄水が補給される。   When the water level in the tank main body 1 decreases with the drainage of the cleaning water and falls to the opening at the upper end of the control cylinder 5, the cleaning water in the tank main body 1 does not flow into the control cylinder 5 and further in the tank main body 1. A large amount of the wash water is drained from the drain port 32, and the water level rapidly decreases. In parallel with this, water in the control cylinder 5 flows out from the small through hole 51 on the bottom surface of the control cylinder 5 and the float body 7 also descends. However, since the outflow amount from the small through hole 51 is small, the control cylinder 5 The lowering of the internal water level is slow, and it falls slowly over time. Therefore, the upper end of the drainage port 32 in the tank body 1 (DWL1 in FIG. 1) until the above-described floating body 7 is lowered to the lower part in the control cylinder 5 and the drainage valve body 31 is seated on the drainage port 32. All of the wash water except the part below is drained and drainage is complete. That is, at the time of large washing, all the water that can be discharged by opening the drain valve 3 in the tank body 1 is drained. After the drain valve 3 is closed, water is supplied from the ball tap water tap 2 in the upper part of the tank body 1, and cleaning water is replenished to the upper limit water level in the tank body 1.

小洗浄に際して操作ハンドル8を小洗浄側に回動すると、オーバーフロー管引き上げ部材92が所定角度回動し、連結部材10を介してオーバーフロー管15が引上げられて排水弁体31が開弁し、便器に対する給水が開始される。これと同時に、小洗浄用パイロット弁引き上げ部材91がオーバーフロー管引き上げ部材92の回動と同調して回動し、これにより連結部材11が引上げられて小洗浄用パイロット弁4を開弁する。排水に伴ってタンク本体1内水位が低下し、制御筒5上端の開口部以下にまで低下すると、制御筒5の大通孔52が大きく開口されているため、制御筒5内の水が大通孔52を介して速やかに流出し、制御筒5内の水位もタンク本体1内の水位低下と略同じ速度で急速に低下する。   When the operation handle 8 is rotated to the small cleaning side during the small cleaning, the overflow pipe lifting member 92 is rotated by a predetermined angle, the overflow pipe 15 is pulled up via the connecting member 10 and the drain valve body 31 is opened, and the toilet bowl is opened. Water supply to is started. At the same time, the small cleaning pilot valve lifting member 91 rotates in synchronism with the rotation of the overflow pipe lifting member 92, whereby the connecting member 11 is pulled up and the small cleaning pilot valve 4 is opened. When the water level in the tank main body 1 decreases with drainage and falls below the opening at the upper end of the control cylinder 5, the large through hole 52 of the control cylinder 5 is opened widely. The water level in the control cylinder 5 quickly flows out through 52, and the water level in the control cylinder 5 rapidly decreases at substantially the same speed as the water level in the tank body 1 decreases.

制御筒5内の浮き子体7が同容器5下部まで降下し、タンク本体1内水位が小洗浄時における下限水位(図1のDWL2)まで低下した時、浮き子体7と共に降下する排水弁体31が排水口32に着座して閉弁する。小洗浄用パイロット弁4も浮き子体7と同様に降下するため、排水弁体31の閉弁と略同時に閉弁する。排水弁3が閉弁した時点において、タンク本体1内には制御筒5下面以下の範囲に洗浄水が残っており、この残留水の分(DWL1とDWL2との差の分)、便器に対して供給される洗浄水の量が削減されることになる。   A drainage valve that descends together with the float body 7 when the float body 7 in the control cylinder 5 descends to the bottom of the container 5 and the water level in the tank body 1 falls to the lower limit water level (DWL2 in FIG. 1) at the time of small washing. The body 31 sits at the drain port 32 and closes. Since the small cleaning pilot valve 4 also descends in the same manner as the float body 7, it closes substantially simultaneously with the closing of the drain valve body 31. At the time when the drain valve 3 is closed, flush water remains in the tank body 1 in the range below the lower surface of the control cylinder 5, and this residual water (the difference between DWL1 and DWL2) Therefore, the amount of cleaning water supplied will be reduced.

以上説明したように、便器洗浄タンク装置aにあっては、従来のもののように、制御筒側面に、該制御筒内の水の流出速度を制御する開閉弁蓋を配設し、該開閉弁蓋の遅延閉止にダンパー機構を使用する必要がなく、小洗浄用パイロット弁4の開閉にて制御筒5内の水の流出速度を制御することができる。したがって、軽い力で制御筒5に設けられた小洗浄用パイロット弁4を開閉可能として、確実に大小洗浄を切替動作させることができる。   As described above, in the toilet flushing tank apparatus a, as in the conventional case, an open / close valve lid for controlling the flow rate of water in the control cylinder is disposed on the side of the control cylinder, and the open / close valve It is not necessary to use a damper mechanism for delaying closing of the lid, and the outflow speed of water in the control cylinder 5 can be controlled by opening and closing the small washing pilot valve 4. Therefore, the small cleaning pilot valve 4 provided in the control cylinder 5 can be opened and closed with a light force, and the large and small cleaning can be switched reliably.

図3から図5に基づいて、制御筒5における格納部54と該小洗浄用パイロット弁4の関係について更に説明する。図3は、制御筒に配設した小洗浄用パイロット弁4の格納部54を示す斜視図であり、図4は、小洗浄用パイロット弁4のフロート42を示す斜視図であり、図5は、格納部54と小洗浄用パイロット弁4の位置関係を示す上面図である。図3に示すように、制御筒5の外周部には、小洗浄用パイロット弁4を格納する格納部54が形成されている。この格納部54は内面が円筒状であり、制御筒5とはスリット状の連通路54aによって繋がっている。また、図4に示すように、小洗浄用パイロット弁4のフロート42の外周面から他方に向かってリブ43を突設形成する。そして、図5に示すように、リブ43が格納部54の内壁と対向する構成となっている、従って、操作ハンドル8を小洗浄側に回動し、小洗浄用パイロット弁4をタンク上方へ引上げる際、前記格納部54の内壁と前記リブ43が当接する。なお、リブ43は小洗浄用パイロット弁4のフロート42の外周面に突設形成する構成に限定されることはなく、前記格納部54の内周面から他方に向かって突設形成する構成としてもよい。   Based on FIGS. 3 to 5, the relationship between the storage portion 54 in the control cylinder 5 and the small cleaning pilot valve 4 will be further described. 3 is a perspective view showing the storage portion 54 of the small cleaning pilot valve 4 disposed in the control cylinder, FIG. 4 is a perspective view showing the float 42 of the small cleaning pilot valve 4, and FIG. FIG. 6 is a top view showing the positional relationship between the storage portion 54 and the small cleaning pilot valve 4. As shown in FIG. 3, a storage portion 54 for storing the small cleaning pilot valve 4 is formed on the outer peripheral portion of the control cylinder 5. The storage portion 54 has a cylindrical inner surface and is connected to the control cylinder 5 by a slit-like communication path 54a. Further, as shown in FIG. 4, a rib 43 is formed to project from the outer peripheral surface of the float 42 of the small cleaning pilot valve 4 toward the other side. As shown in FIG. 5, the rib 43 is configured to face the inner wall of the storage portion 54. Accordingly, the operation handle 8 is rotated to the small washing side, and the small washing pilot valve 4 is moved upward. When pulling up, the inner wall of the storage portion 54 comes into contact with the rib 43. The rib 43 is not limited to a configuration in which the rib 43 protrudes from the outer peripheral surface of the float 42 of the pilot valve 4 for small cleaning, but a configuration in which the rib 43 projects from the inner peripheral surface of the storage portion 54 toward the other. Also good.

前記リブ43を突設形成することにより、格納部54とフロート42の摺動抵抗を低減することができる。したがって、軽い力で制御筒5に設けられた小洗浄用パイロット弁4を開閉可能として、確実に大小洗浄を切替動作させることができる。   By forming the rib 43 in a projecting manner, the sliding resistance between the storage portion 54 and the float 42 can be reduced. Therefore, the small cleaning pilot valve 4 provided in the control cylinder 5 can be opened and closed with a light force, and the large and small cleaning can be switched reliably.

次に、小洗浄用パイロット弁4を引き上げる際の、小洗浄用パイロット弁引き上げ部材91とこの小洗浄用パイロット弁4とを繋ぐ連結部材11の動作について、図6〜図8に基づいて説明する。
図6は、小洗浄用パイロット弁4、小洗浄用パイロット弁引き上げ部材91および連結部材11の位置関係を示す断面図、図7は、小洗浄用パイロット弁4の格納部54の上部に円筒部材55を配設した場合を示す他の実施例であり、図8は、円筒部材55の変形例として円筒部材55の上端部を徐拡大した場合を示す断面図である。図6(b)に示すように、小洗浄用パイロット弁4と該小洗浄用パイロット弁4をタンク上方へ引き上げる小洗浄用パイロット弁引き上げ部材91の跳ね上げ面91aとの位置関係は、小洗浄用パイロット弁4が閉弁状態においては、跳ね上げ面91aは小洗浄用パイロット弁4の略垂直上方に位置している。つまり連結部材11は略垂直状態を維持している。ここで操作ハンドル8にて小洗浄側へ回動すると(図6(a)に示す)、小洗浄用パイロット弁4は跳ね上げ面91aの回動により引き上げ部材11を介してタンク上方へ引き上げられる。このとき跳ね上げ面91aは所定の回動角度回動するため、跳ね上げ面91aの回動終了時、跳ね上げ面91aは小洗浄用パイロット弁4の垂直上方から外れた位置にくる。つまり連結部材11も小洗浄用パイロット弁4に対して垂直を維持できない状態となる。このときの垂直方向からのずれ角度をβとする。そのため、小洗浄用パイロット弁4は垂直方向に引き上げられず、垂直方向よりも角度βずれた方向に引き上げられることになる。このときの小洗浄用パイロット弁4の位置を破線にて示す。これにより小洗浄用パイロット弁4は格納部54内壁に接触しながらタンク上方へ引き上げられることになる。そのため、パイロット弁4のフロート42外壁と格納部54内壁の間に摺動抵抗が発生し、小洗浄用パイロット弁の引き上げ荷重が増加する。
Next, the operation of the connecting member 11 that connects the small cleaning pilot valve lifting member 91 and the small cleaning pilot valve 4 when the small cleaning pilot valve 4 is lifted will be described with reference to FIGS. .
6 is a cross-sectional view showing the positional relationship between the small cleaning pilot valve 4, the small cleaning pilot valve lifting member 91, and the connecting member 11. FIG. 7 is a cylindrical member above the storage portion 54 of the small cleaning pilot valve 4. FIG. 8 is a cross-sectional view showing a case where the upper end portion of the cylindrical member 55 is gradually enlarged as a modified example of the cylindrical member 55. As shown in FIG. 6 (b), the positional relationship between the small cleaning pilot valve 4 and the flip-up surface 91a of the small cleaning pilot valve lifting member 91 that lifts the small cleaning pilot valve 4 to the upper side of the tank is small cleaning. When the pilot valve 4 is closed, the flip-up surface 91a is positioned substantially vertically above the small washing pilot valve 4. That is, the connecting member 11 maintains a substantially vertical state. When the operation handle 8 is rotated to the small washing side (shown in FIG. 6 (a)), the small washing pilot valve 4 is lifted to the upper side of the tank through the lifting member 11 by the rotation of the flip-up surface 91a. . At this time, since the flip-up surface 91a rotates by a predetermined rotation angle, the flip-up surface 91a comes to a position deviated from the vertical upper side of the small washing pilot valve 4 at the end of the rotation of the flip-up surface 91a. That is, the connecting member 11 is also in a state where it cannot maintain the vertical with respect to the small cleaning pilot valve 4. The angle of deviation from the vertical direction at this time is β. Therefore, the small cleaning pilot valve 4 is not lifted in the vertical direction, but is lifted in a direction shifted by an angle β from the vertical direction. The position of the pilot valve 4 for small cleaning at this time is indicated by a broken line. As a result, the small cleaning pilot valve 4 is lifted upward while contacting the inner wall of the storage portion 54. Therefore, sliding resistance is generated between the outer wall of the float 42 of the pilot valve 4 and the inner wall of the storage portion 54, and the lifting load of the small cleaning pilot valve increases.

ここで、図7に示すように、格納部54の上部に該格納部54よりも内径が小さい円筒部材55を配設する。この円筒部材55の中を前記小洗浄用パイロット弁と連結された連結部材11が挿通することにより、小洗浄用パイロット弁4を引き上げる場合において、跳ね上げ面91aと小洗浄用パイロット弁4の位置関係が角度βずれたとしても、連結部材11は円筒部材55の内壁に沿う形態で小洗浄用パイロット弁4を引き上げるため、パイロット弁4は略垂直状態を保持したまま、タンク上方へ引き上げることが可能となり、軽い力で制御筒5に設けられた小洗浄用パイロット弁4を開閉可能として、確実に大小洗浄を切替動作させることができる。   Here, as shown in FIG. 7, a cylindrical member 55 having an inner diameter smaller than that of the storage portion 54 is disposed above the storage portion 54. When the connecting member 11 connected to the small cleaning pilot valve is inserted through the cylindrical member 55, the position of the flip-up surface 91a and the small cleaning pilot valve 4 is increased when the small cleaning pilot valve 4 is pulled up. Even if the relationship is shifted by an angle β, the connecting member 11 pulls up the small cleaning pilot valve 4 along the inner wall of the cylindrical member 55, so that the pilot valve 4 can be lifted upward while maintaining a substantially vertical state. The small washing pilot valve 4 provided in the control cylinder 5 can be opened and closed with a light force, and the large and small washing can be switched reliably.

また図8に示すように、円筒部材55の上端部55aを徐拡大することにより、連結部材11の屈曲を防止し、連結部材11と円筒部材54の摺動抵抗も減少可能となるため、小洗浄用パイロット弁4の引き上げ荷重を更に低減することができる。 Further, as shown in FIG. 8, by gradually expanding the upper end portion 55a of the cylindrical member 55, the bending of the connecting member 11 can be prevented and the sliding resistance between the connecting member 11 and the cylindrical member 54 can be reduced. The lifting load of the cleaning pilot valve 4 can be further reduced.
