201237239 六、發明說明： 【發明所屬之技術領域】 本發明係有關於便器洗淨水箱。 【先前技術】 作為習知的便器洗淨水箱，已知設有2個開閉水箱本體的 排水口之排水閥，且分別連繫有圓珠鏈條。此等圓珠鏈條分 別安裝有1個浮筒（float)。此便器洗淨水箱係藉由使浮筒安 裝至此等圓珠鏈條的安裝高度不同，可使大清洗時的排出水 量增多，並使小清洗時的排出水量減少。 但是，此便器洗淨水箱的2個浮筒會佔據水箱本體内許多 的空間。近年，因為便器洗淨水箱的小型化，而使水箱本體 的内部空間狹小化，故不希望2個浮筒佔據過多水箱本體内 的空間。 因此，在專利文獻1〜專利文獻4中揭示有僅具備1個浮 筒的其他之習知便器洗淨水箱。在專利文獻1與2中所揭示 的便器洗淨水箱係具備有：分開為上部閥體與下部閥體的瓣 閥(flapper valve)、分別連接於上部閥體與下部閥體的2條 圓珠鏈條、以及安裝在與上部閥體連接續的圓珠鏈條之1 個浮筒。下部閥體具有保持空氣的空氣室。另外，此空氣室 並無法保持空氣或排放空氣。 再者，專利文獻3所揭示的便器洗淨水箱係具備有：具有 空氣室的瓣閥、作為開閉空氣室之空氣活門的蓋部、連接於 101103225 3 201237239 蓋部的圓珠鏈條、以及安裝在圓珠鏈條上的丨個浮筒。 此便器洗淨水箱，圖18所示，在開閉排水口的瓣閥2〇〇 设置有空氣室202。平常時，蓋部2〇4係利用磁鐵206、208 的磁吸力，保持將空氣室202的上端開口封閉之狀態。浮筒 212係安裝於與蓋部204連接的圓珠鏈條。 此便器洗淨水箱係設定為利用磁鐵2〇6、2〇8的磁吸力， 將蓋部204從瓣閥200上拉而開放空氣室2〇2的力比反抗水 箱本體内所儲存洗淨水的水壓，將瓣閥2〇〇上拉而開閥的力 強。 所以，此便器洗淨水箱若將圓珠鏈條210上拉，首先瓣閥 200會被上拉而開閥，然後若將圓珠鏈條210上拉，則蓋部 204就會開啟使水箱本體内的洗淨水流入空氣室202内。 瓣閥200係在蓋部204封閉的狀態下，因為空氣室202 内充滿空氣，因而產生浮力。所以，瓣閥200可維持較久的 開閥狀態，俾使便器洗淨水箱能排出大量之洗淨水而執行大 清洗。另一方面，在瓣閥200開閥之後，若蓋部204被從瓣 閥200上拉而成為開啟狀態，就會排放空氣室2〇2内的空 氣，俾使洗淨水流入空氣室202内。所以’瓣閥200因為並 未產生浮力而無法維持較久的開閥狀態’因此便器洗淨水箱 就會執行排出少量之洗淨水的小清洗。 再者，專利文獻4所揭示的便器洗淨水箱係具有：1個瓣 閥、連接於此瓣閥的1條圓珠鏈條、以及固定於此圓珠鏈條 101103225 4 201237239 的1個浮筒。瓣閥係設有具排氣孔的空氣室。此瓣閥可利用 栓體封閉排氣孔而使空氣室内保持空氣、或取下栓體開放排 氣孔而使洗淨水流入空氣室内。如此一來，此瓣閥就可變更 浮力。所以，此便器洗淨水箱可根據所安裝水洗式便器的種 類等，變更所排出洗淨水的水量。 再者，在專利文獻5與6揭示有將連結於排水閥的圓珠鏈 條上拉之旋轉軸，此旋轉軸係連結於洗淨把手，且以軸心為 中心旋轉自如地安裝於水箱本體。此旋轉軸係在前端部設有 連結大清洗用之圓珠鏈條與小清洗用之圓珠鏈條的連結 部。具有已安裝此旋轉軸之水箱本體的便器洗淨水箱，若使 旋轉軸朝一方向旋轉，就會使大清洗用之圓珠鏈條被上拉而 執行排出大量之洗淨水的大清洗洗淨水箱係若 使旋轉軸朝反方向旋轉，就會使小清洗用之圓珠鏈條被上拉 而執行排出較大清洗更少水量之洗淨水的小清洗。 此旋轉軸312如圖19所示，具有：連結於洗淨把手302 的軸部300、以及在軸部3〇〇前端言免置為分開之個體的臂部 304。臂部綱具有筒部篇。f部綱在將轴部雇前端 部插入㈣的狀態下，利職合銷_結合於轴部 ，。旋可編合於細部的螺帽31〇固定於 洗淨水相本體的水箱壁。 臂部綱係位於柏部的前端側，其具有：朝下方延伸 的板狀側壁部3M'以及從侧壁部314朝夹住Μ # 101103225 201237239 心的兩方向延伸之平板部316。平板部316具有在設置在兩 端部的連結部318、329。-連結部318係連結大清洗用之 圓珠鏈條322 ’另-連結部320係連結小清洗用之圓珠鍵條 324。 此旋轉軸312若將洗淨把手302朝順時針方向旋轉，就可 將大清洗用之圓珠鏈條322上拉，若將洗淨把手3〇2朝逆時 針方向旋轉，就可將小清洗用之圓珠鏈條324上拉。 再者，作為白知之另一便器洗淨水箱，已知具備有設置於 水箱本體之水箱壁的洗淨把手、連結於此洗淨把手且朝水箱 本體内延伸的旋轉軸、開閉水箱本體的排水口之排水閥、以 及連結於旋轉軸與排水閥之間且具有可挽性的上拉材者。 此便器洗淨水箱對從水箱本體以前視觀察時，通常係將洗 淨把手安裝於右側的水箱壁之外表面（所謂「右把手規 格」）。但是，例如在集合住宅中，因為在右側的水箱壁附 近會有配管通過等理由，所以存在有難以在右側水箱壁安裝 洗淨把手的情況。此情況，就會在左側水箱壁安裝洗淨把手 (所謂「左把手規格」）。 所以’必須根據右把手規格與左把手規格準備不同的排水 闊。即’在右把手規格的情況下，連結設置於排水閥之上拉 材之下端側的安裝部，通常係設置於較排水閥左右方向的中 心更靠右側。因為此排水閥無法對應左把手規格，因此必須 另外準備將安裝部設置於較左右方向的中心更靠左側的排 101103225 6 201237239 水閥。 但是，左把手規格相較於右把手規格，需求極少僅為ι% 左右’僅管如此但為了對應右把手規格與左把钱格，仍必 鮮備不同的排水閥，會導致庫存管理複純，且成為成本 提间之主要原因等，不具經濟效益。 專利文獻7的圖3與圖4揭示有利用伸縮自如機構而將排 水閥的上拉部設置於水箱本體的中央處，藉此可將洗淨把手 安裝於左右任一側的水箱壁者。此排水閥具有將上拉材連結 於中心部的安裝部。 再者，專利文獻8揭示有將各自不同的上拉材連結於上下 重登的2賴閥，並藉由洗淨把手的操作而切換大小清洗 者。 [先行技術文獻] [專利文獻] 專利文獻1:日本專利特開平10_183719號公報 專利文獻2:日本專利特開2〇〇3_27554號公報 專利文獻3 :美國專利第6263520號說明書 專利文獻4:日本專利特開2〇〇8_156898號公報 專利文獻5

意願而執行大清洗。 思反 再者，專利文獻4的便器洗淨水箱係在利用检體封 孔之後、或從排氣孔卸除栓體將其開放之後，於該狀離礼 用因此，此便器洗淨水箱無法在每次執行便器洗淨時 萬地使排出之洗淨水的水量不同。 、 第1發明與第2發明係有鑑於上述習知之實情而完成者， 其應解紅課題在於提供可安錄行大清洗如、清洗的便 器洗淨水箱。 再者，如圖19所示，專利文獻5與6的旋轉軸312，由 於ί 4 3〇4較大’因此若將臂部3〇4與軸部獅形成一體構 w ’便無法將固定用之螺帽31〇插穿於軸部3〇〇。因此，此 旋轉軸312係形成為與臂部3〇4及轴部3〇〇為不同個體之構 =於此情況下，旋轉軸312的零件數量會變多，導致成本 提南。又’臂部3G4佔據水箱本體内許多的空間。此情況對 近年來便H洗淨水箱的小型化、水箱本體_部空間狹小化 而言並不樂見。 第3發明係有鑑於上述習知之實情而完成者，其應解決之 課題在於提供可實現小型化的便器洗淨水箱。 101103225 8 201237239 再者，在專利文獻7的便器洗淨水箱中，當從左右方向的 中心朝左右偏移之位置處設置上拉材之安裝部的排水閥之 情形時，無法對應右把手規格與左把手規格雙方。又，專利 文獻8的便器洗淨水箱亦無論是右把手規格的猜況、或左把 手規格的情況，均無法以相同的排水閥對應。 第4發明係有鑑於上述習知之實情而完成者，其應解決之 課題在於提供無論洗淨把手為右把手規格或左把手規格，均 可使用同一排水閥對應的便器洗淨水箱。 (解決問題之手段） 第1發明的便器洗淨水箱，係將洗淨水供應至水洗式便器 的便器洗淨水箱，其特徵在於具備有： 水箱本體，其儲存洗淨水，且於底部具有排水口； 排水閥，其具有空氣室及空氣活門，在此空氣活門為閉閥 狀態或開閥狀態下開放上述排水口；該空氣室係於内部保持 空氣；該空氣活門係利用上拉來開閥，用以排放上述空氣室 内的空氣’俾使上述水箱本體内所儲存的洗淨水流入上述空 氣室内；以及 上拉材，其在上述空氣活門為閉閥之狀態、或上述空氣活 門被上拉而為開閥之狀態下，將上述排水閥上拉而開閥。 此便器洗淨水箱係在空氣活門為閉閥之狀態下，可使排水 閥開閥。於此情況時，利用空氣室内充滿之空氣所產生的浮 力可發揮維持排水閥為開閥狀態的作用。所以，便器洗淨水 101103225 9 201237239 箱因為排水閥之開閥狀態變長’故可執行來自水箱本體的洗 淨水之排出量較多之大清洗。 再者，此便器洗淨水箱係將空氣活門開閥後，可在空氣活 門為開闊之狀態下使排水閥開閥。於此情況時，排水闕因為 空氣室内的空氣已排放並流入儲存於水箱本體内的洗淨 水，因此不會產生浮力。所以’便器洗淨水箱因為排水閥的 開閥狀態縮短’因此可執行來自水箱本體的洗淨水之排出量 較少之小清洗。如此，此便器洗淨水箱在執行小清洗時，首 先使空氣活門開閥，並在該狀態下開啟排水閥，因此可確實 地防止違反意願的執行大清洗。 所以，第1發明的便器洗淨水箱可安定地執行大清洗與小 清洗。 第2發明的便器洗淨水箱’係將洗淨水供應至水洗式便器 的便器洗淨水箱，其特徵在於具備有： 水箱本體’其儲存洗淨水，且於底部具有排水口； 排水閥，其具有空氣室及空氣活門，用以開放上述排水 口；該空氣室係於内部保持空氣；該空氣活門係利用上拉來 開閥，排放上述空氣室内的空氣，俾使上述水箱本體内所儲 存的洗淨水流入上述空氣室内； 上拉材，其將上述排水閥上拉而開閥； 浮筒，其沿著此上拉材移動自如地設置； 擋止，其在此浮筒的上側固定於上述上拉材，並使上述浮 101103225 _ 201237239 筒從下方抵接，使其承受此浮筒的浮力；以及 傳遞構件，其設置於離開抵接於此擋止之狀態的上述浮筒 之下端設定距離之下側位置處，當上述浮筒下降時承受此浮 筒的重量，使上述排水閥朝下方向移動。 此便器洗淨水箱在空氣活門為閉閥之狀態下，可使排水閥 開閥。於此情況時，利用空氣室内充滿空氣所產生的浮力， 發揮維持排水閥為開閥狀態的作用。因此，便器洗淨水箱因 為排水閥之開_態變長，俾可執行來自水箱本體的洗淨水 之排出量較多之大清洗。此便器洗淨水箱在執行大清洗時， 使利用空氣室所充滿之空氣而具有浮力的排水閥，藉由承受 浮筒之重量的傳遞構件而朝下方向移動便可閉閥。 再者，此便器洗淨水箱係藉由使空氣活門及排水閥開閥， 便可執行小清洗。即，在空氣活門為開閥之狀態下，因為空 氣室内的空氣已排放，因此排水閥不會產生浮力。所以，僅 利用浮筒浮力使排水閥維持在開閥之狀態，排水閥的開閥狀 ‘ 態會縮短，而執行來自水箱本體的洗淨水之排出量較少之小 . 清洗。 如此，此便器洗淨水箱係藉由1個浮筒發揮作為錘的作 用、或發揮原本浮筒的作用，便可切換執行大清洗與小清 洗。又，藉由使承受浮筒重量的傳遞構件之長度產生變化， 便可變更執行大清洗時排水閥閉閥的時序。即，可變更執行 大清洗時洗淨水之排出水量。 101103225 11 201237239 所以’第2發明的便器洗淨水箱可安定地 清洗。 ^亍大清洗與小 再者’此便器洗淨水箱因為所需的浮筒σ 、要1個便足夠， 因此可減少水相本體内浮筒所佔據的空問 间，故可成為小型 化0 第3發明的便器洗淨水箱，係將洗淨水供應至水洗式便器 的便器洗淨水箱，其特徵在於具備有： 水箱本體，其儲存洗淨水，且於底部具有排水口. 排水閥，其開閉上述排水口； 第1上拉材，其連結於上述排水閥，當執行從上述排水口 排放大量洗淨水的大清洗時，將上述排水.拉使闊開 啟； 第2上拉材，其連結於上述排水閥，當執行從上述排水口 排放較上述大清洗更少的洗淨水的小清料，將上述排水闕 上拉使閥開啟；以及 旋轉軸，其具備有軸部及臂部；該轴部係以車由心為中心旋 轉^如地絲社述水箱本體上朝上述水箱本體内延伸，且 在前端部具有連結部，該連結刺將纽上述心的兩侧中 之-側連結於上述第！上拉材的上部，並將另一側連結於上 述第2上拉材的上部；該臂部係在垂下的上述第】上拉材與 j第2上拉材之間’從上述軸部的前端軸下方延伸，並 隨著上述轴部的旋轉-起旋轉，若使上述轴部朝一方向旋轉 10Π03225 12 201237239 就會將上述第1上拉材上拉，若使上述軸部朝反方向旋轉就 會將上述第2上拉材上拉。 此便益洗淨水箱若將軸部朝一方向旋轉，臂部就會將第1 上拉材上拉’若將軸部朝反方向旋轉’臂部就會將第2上拉 材上拉。即，此便器洗淨水箱在第1上拉材與第2上拉材之 間具有從軸部的前端部朝下方延伸的臂部，藉由將軸部旋 轉，臂部的前端部就會勾住第1上拉材或第2上拉材之其中 一者，便可將第1上拉材或第2上拉材上拉。 如此，此便器洗淨水箱因為並不需將第丨上拉材與第2 上拉材相對於軸部的軸心較大地分開於兩側而連結，因此不 需將連結部從軸部朝兩側突出地設置。即，可將第丨上拉材 與第2上拉材的連結部相靠近地設置。又，因為臂部係從軸 部的前端部朝下方延伸所形成，因此可將連結部與臂部小型 化，便可縮小此等在水箱本體内所佔據的空間。 所以，第3發明的便器洗淨水箱可實現小型化。 第4發明的便器洗淨水箱，係將洗淨水供應至水洗式便器 的便器洗淨水箱’其特徵在於具備有： 水箱本體，其儲存洗.淨水，且於底部具有排水口； 旋轉軸，其安裝於此水箱本體上朝上述水箱本體内延伸； 上拉材，其連結於此旋轉軸的前端部；以及 排水閥，其開閉上述排水口，且具有將上述上拉材之下端 分別連結於以前視觀察上述水箱本體時較左右方向的中心 101103225 13 201237239 更罪右側及左侧處的安裂部。 此便器洗淨水箱在洗淨把手安裝於右側水箱壁的右把手 規格之情形時，可將上拉材連結於右側的安裝部。又，此便 器洗淨水相在洗淨把手安裝於左側水箱壁的左把手規格之 情形時，可將上拉材連結於左侧的安裝部。 所以’第4發明的便器洗淨水箱無論洗淨把手為右把手規 格或左把手規格，，均可使用同一個排水閥對應。 再者，此便器洗淨水箱可減少所需排水閥的種類，俾實現 成本之降低。 【實施方式】 針對第1發明的較佳實施形態進行說明。 在第1發明中，可使為了將上述空氣活門上拉而開閥時所 需的力，小於為了將上述排水閥上拉而開閥時所需的力。於 此情況時’當執行小清洗時，在上拉材確實地上拉空氣活門 而開闊後’可在空氣活門為開閥之狀態下，上拉排水閥而開 閥。 第1發明的空氣活門可具有朝向下之閉閥方向賦予彈力 的彈性構件《於此情況時，當便器洗淨水箱執行小清洗時 在排水閥開閥後，利用彈性構件的彈力使排水閱對空氣活門 相對地快速朝上方移動，使空氣活門自動地閉閥。所以，a 防止在其後當排水閥閉閥時所發生之止水不良。 性構件的彈力可防止空氣室内的空氣將空氣活 又，利用彈 門上推而漏 101103225 14 201237239 出。所以，當便器洗淨水箱執行大清洗時，可利用空氣室内 的空氣產生浮力，而文疋地且較長時間地維持排水間的開閥 狀態，便可將水箱本體内所儲存的洗淨水以一定的安定之水 量排出。 再者’第1發明的上拉材可由直接連結於上述排水閥的第 1上拉材、與連結於上述空氣活門的第2上拉材所構成。於 此情況時’藉由上拉第1上拉材可直接地將排水閥開閥而執 行大清洗。另一方面，藉由上拉第2上拉材便可執行小清 洗。所以，此便器洗淨水箱可確實地區分且切換而執 洗與小清洗。 β 再者，第1發明的上拉材係連結於上述空氣活門，而上述 空氣活門可具有鎖定為閉閥狀態的鎖定裝置。於此情況時， 若在鎖定裝置將空氣活門鎖定為閉閥狀態的狀態下將上拉 材上拉，就會僅使排水閥開閥而可執行大清洗。又，若在鎖 定裝置未將空氣活門鎖定為閉閥狀態的狀態下將上拉材上 拉，就會在空氣活門開閥後使排水閥開閥而可執行小清洗。 所以，此便器洗淨水箱可確實地區分且切換而執行大清洗與 小清洗。 再者，第1發明的空氣室可設置於上述排水的下部。於此 情況時，因為當排水閥閉閥時可將空氣室設在水箱本體外， 故可贯現水箱本體之小型化。 接著’針對第2發明的較佳實施形態進行說明。 101103225 15 201237239 第2發明的傳遞構件可與上述排水閥為分開之個體◊於此 情況時，可輕易地變更傳遞構件的長度。藉由變更傳遞構件 的長度’便可輕易地變更承受浮筒之重量而使排水閥開始閉 閥的時期β所以，此便器洗淨水箱可輕易地變更在執行大清 洗時所排出洗淨水的水量。 第2發明的排水闊可具有導引上述上拉材的導引部。於此 情況時，可防止上拉材朝其他方向不規則地傾倒。所以，此 便器洗淨水所排出洗淨水的水量並不會不同於所設定的水 量，可適切地排出所設定的洗淨水量。 接著，針對第3發明的較佳實施形態進行說明。 第3發明的臂部可具有防止上述第丨上拉材與上述第2 上拉材從二側面朝外侧偏移的防偏部。於此情況時，可防止 第1上拉材與第2上拉材朝外側偏移。所以，此便器洗淨水 箱可防止因為臂部無法上拉此等上拉材而發生無法使排水 閥開閥的情形。 接著，針對第4發明的較佳實施形態進行說明。 第4發明的安裝部可相對於上述排水閥的上述左右方向 中〜為左右對稱之形狀。於此情況時，在將洗淨把手安裝於 右侧水箱壁而成為右把手規格的情況、或將洗淨把手安裝於 左側水箱壁而成為左把手規格的情況下，旋轉轴前端部與開 閉閥安裝部間之相對位置關係，除了左右對稱之外其餘均為 相同所以，無論在右把手規格或左把手規格的任一情況 101103225 201237239 下，旋轉軸前端部與開閉閥安裝部可利用上拉材同樣地連 結，且洗淨操作時亦是可以同樣的方式使開閉閥進行開閉。

Description of the Invention: [Technical Field to Be Invented] The present invention relates to a toilet flushing water tank. [Prior Art] As a conventional toilet flushing water tank, it is known to provide two drain valves for opening and closing the water tank main body, and a bead chain is attached thereto. These bead chains are each equipped with a float. The toilet washing water tank can increase the amount of discharged water during large washing by reducing the installation height of the float to the bead chain, and reduces the amount of discharged water during small washing. However, the two floats of the toilet tank will occupy a lot of space in the tank body. In recent years, the size of the toilet tank has been reduced, and the internal space of the tank body has been narrowed. Therefore, it is not desirable for the two floats to occupy too much space in the tank body. Therefore, Patent Documents 1 to 4 disclose other conventional toilet water tanks having only one float. The toilet washing water tank disclosed in Patent Documents 1 and 2 is provided with a flapper valve that is divided into an upper valve body and a lower valve body, and two ball beads that are respectively connected to the upper valve body and the lower valve body. A chain and a float mounted on a bead chain connected to the upper valve body. The lower valve body has an air chamber that holds air. In addition, this air chamber does not retain air or discharge air. Further, the toilet washing water tank disclosed in Patent Document 3 includes a flap valve having an air chamber, a lid portion as an air shutter for opening and closing the air chamber, a ball chain connected to a cover portion of 101103225 3 201237239, and a bead chain attached thereto. A pontoon on the bead chain. In the toilet washing tank, as shown in Fig. 18, an air chamber 202 is provided in the flap valve 2 of the opening and closing drain port. Normally, the lid portion 2〇4 maintains the state in which the upper end opening of the air chamber 202 is closed by the magnetic attraction of the magnets 206 and 208. The pontoon 212 is attached to a bead chain connected to the lid portion 204. The toilet washing water tank is set to use the magnetic force of the magnets 2〇6, 2〇8 to pull the lid portion 204 from the flap valve 200 to open the air chamber 2〇2 to counteract the washing water stored in the tank body. The water pressure is strong, and the valve valve 2 is pulled up to open the valve. Therefore, if the toilet water tank pulls up the ball chain 210, firstly the flap valve 200 will be pulled up to open the valve, and then if the ball chain 210 is pulled up, the cover portion 204 will be opened to make the water tank body The washing water flows into the air chamber 202. The flap valve 200 is in a state in which the lid portion 204 is closed, and buoyancy is generated because the air chamber 202 is filled with air. Therefore, the flap valve 200 can maintain a relatively long open state, and the toilet flushing tank can discharge a large amount of washing water to perform a large cleaning. On the other hand, after the flap valve 200 is opened, if the lid portion 204 is pulled up from the flap valve 200 to be in an open state, the air in the air chamber 2〇2 is discharged, so that the washing water flows into the air chamber 202. . Therefore, the flap valve 200 cannot maintain the valve opening state for a long time because it does not generate buoyancy. Therefore, the toilet flushing tank performs a small washing for discharging a small amount of washing water. Further, the toilet washing water tank disclosed in Patent Document 4 has one flap valve, one bead chain connected to the flap valve, and one float fixed to the bead chain 101103225 4 201237239. The flap valve is provided with an air chamber having a venting opening. The flap valve can close the vent hole by the plug body to keep the air in the air chamber or remove the plug open vent hole to allow the washing water to flow into the air chamber. In this way, the flap valve can change the buoyancy. Therefore, the toilet water tank can change the amount of water discharged from the washing water depending on the type of the toilet to be installed. Further, Patent Documents 5 and 6 disclose a rotating shaft that pulls up a ball chain connected to a drain valve, and the rotating shaft is coupled to a washing handle, and is rotatably attached to the tank body around the axis. In the rotating shaft, a connecting portion for connecting the ball chain for large cleaning and the ball chain for small cleaning is provided at the front end portion. A toilet washing water tank having a water tank body to which the rotating shaft is mounted, if the rotating shaft is rotated in one direction, the large-purifying ball chain is pulled up to perform a large washing water tank for discharging a large amount of washing water. When the rotating shaft is rotated in the reverse direction, the ball chain for small washing is pulled up to perform small washing of the washing water which discharges a larger amount of washing and less water. As shown in Fig. 19, the rotating shaft 312 has a shaft portion 300 that is coupled to the washing handle 302, and an arm portion 304 that is separated from the front end of the shaft portion 3〇〇. The arm section has a tubular section. In the state in which the front end portion of the shaft portion is inserted (4), the profit-and-sales _ is combined with the shaft portion. The nut 31 that can be knitted into the detail is fixed to the tank wall of the washing water phase body. The arm system is located on the front end side of the cypress portion, and has a plate-like side wall portion 3M' extending downward and a flat plate portion 316 extending from the side wall portion 314 in both directions of the Μ# 101103225 201237239 core. The flat plate portion 316 has coupling portions 318, 329 provided at both end portions. The connecting portion 318 is connected to the ball chain 322 for large cleaning. The other connecting portion 320 is connected to the ball key 324 for small washing. When the rotating shaft 312 rotates the washing handle 302 in the clockwise direction, the ball chain 322 for large cleaning can be pulled up, and if the washing handle 3〇2 is rotated counterclockwise, the small cleaning can be used. The bead chain 324 is pulled up. Further, as another toilet washing tank of the same, it is known that a washing handle provided on the tank wall of the tank body, a rotating shaft connected to the washing handle and extending toward the tank body, and a drain for opening and closing the tank body are known. The drain valve of the mouth, and the pull-up material that is connected between the rotating shaft and the drain valve and has a manageability. When the toilet tank is viewed from the front of the tank body, the washing handle is usually attached to the outer surface of the tank wall on the right side (the so-called "right handle gauge"). However, for example, in a condominium house, there is a case where a pipe is passed in the vicinity of the tank wall on the right side, and there is a case where it is difficult to attach a washing handle to the right tank wall. In this case, a washing handle (the so-called "left handle size") is attached to the left tank wall. Therefore, it is necessary to prepare different drainage widths according to the specifications of the right handle and the specifications of the left handle. In other words, in the case of the right handle specification, the attachment portion that is connected to the lower end side of the pull-up valve is usually placed on the right side of the center in the left-right direction of the drain valve. Since this drain valve cannot correspond to the left handle specification, it is necessary to additionally prepare a row 101103225 6 201237239 water valve in which the mounting portion is disposed on the left side in the center in the left-right direction. However, compared with the size of the right handle, the left handle size is only about ι%. 'Only this is the case. However, in order to correspond to the right handle size and the left handle, there are still different drain valves, which will lead to inventory management. And it becomes the main reason for the cost increase, and it has no economic benefits. Figs. 3 and 4 of Patent Document 7 disclose that the pull-up portion of the drain valve is provided at the center of the tank body by means of a telescopic mechanism, whereby the washing handle can be attached to the tank wall on either side of the left and right sides. This drain valve has a mounting portion that connects the pull-up material to the center portion. Further, Patent Document 8 discloses a method in which a different size of the pull-up material is coupled to the upper and lower retractable valves, and the size cleaner is switched by the operation of washing the handle.

The bead chain is pulled up while being cleaned, but if the amount of operation of the pull-up is insufficient, the cleaning is performed with a small intention. In addition, the toilet washing water tank of Patent Document 4 is opened after the sample is sealed by the sample or after the plug is removed from the vent hole, and thus the toilet water tank cannot be used. The amount of water discharged from the washing water is different for each time the toilet is washed. The first invention and the second invention are completed in view of the above-mentioned conventional circumstances, and the problem to be solved is to provide a toilet water tank that can be cleaned and cleaned. Further, as shown in Fig. 19, the rotation shaft 312 of Patent Documents 5 and 6 is large because ί 4 3〇4, so if the arm portion 3〇4 is formed integrally with the shaft lion, it cannot be used for fixing. The nut 31 is inserted through the shaft portion 3〇〇. Therefore, the rotating shaft 312 is formed to be different from the arm portion 3〇4 and the shaft portion 3〇〇. In this case, the number of parts of the rotating shaft 312 is increased, resulting in cost increase. Further, the arm 3G4 occupies a lot of space in the body of the water tank. In this case, it is not easy to reduce the size of the H-wash tank and the narrowing of the tank body. The third invention has been made in view of the above-described conventional circumstances, and it is an object of the invention to provide a toilet water tank that can be downsized. 101103225 8 201237239 In the case of the toilet flushing water tank of the patent document 7, when the drain valve of the mounting part of the pull-up material is provided from the center of the left-right direction to the left-right direction, the right handle specification and the Both sides of the left handle are specifications. Further, the toilet flushing water tank of Patent Document 8 cannot correspond to the same drain valve regardless of the condition of the right grip gauge or the left grip gauge. The fourth invention has been made in view of the above-described conventional circumstances, and it is an object of the invention to provide a toilet water tank corresponding to the same drain valve regardless of whether the washing handle is a right handle size or a left handle size. (Means for Solving the Problem) The toilet flushing water tank according to the first aspect of the present invention is a toilet washing water tank that supplies washing water to a flush toilet, and is characterized in that: a water tank main body that stores washing water and has a washing water at the bottom a drain valve having an air chamber and an air flap, wherein the air valve is in a closed state or a valve open state; the air chamber is internally kept in air; the air valve is opened by pulling up a valve for discharging air in the air chamber to cause the washing water stored in the water tank body to flow into the air chamber; and a pulling material, wherein the air valve is in a closed state or the air shutter is When the valve is opened, the drain valve is pulled up to open the valve. The toilet flushing water tank is capable of opening the drain valve when the air flap is closed. In this case, the buoyancy generated by the air filled in the air chamber serves to maintain the valve opening state. Therefore, the toilet washing water 101103225 9 201237239 The tank can be opened for a large amount of washing water from the tank body because the valve opening state of the drain valve is long. Furthermore, the toilet flushing water tank can open the air valve after the air valve is opened, and the drain valve can be opened. In this case, the drainage raft does not generate buoyancy because the air in the air chamber has been discharged and flows into the washing water stored in the tank body. Therefore, the toilet flushing water tank is shortened by the valve opening state of the drain valve, so that the washing of the water from the tank body can be performed with a small amount of washing. In this way, when the small washing water tank performs the small washing, the air shutter is first opened, and the drain valve is opened in this state, so that the large cleaning can be surely prevented from being violated. Therefore, the toilet washing tank of the first invention can perform large washing and small washing stably. A toilet flushing water tank according to a second aspect of the present invention is a toilet flushing water tank that supplies washing water to a flush toilet, and is characterized in that: a water tank main body that stores washing water and has a drain port at the bottom; a drain valve, The utility model has an air chamber and an air shutter for opening the water outlet; the air chamber is for holding air inside; the air valve is opened by a pull-up to discharge the air in the air chamber, so that the water tank is stored in the body The washing water flows into the air chamber; the upper pull material pulls up the drain valve to open the valve; the float is movably disposed along the upper pull material; the stop is fixed on the upper side of the float Pulling up the material, and the above-mentioned floating 101103225 _ 201237239 cylinder abuts from below to withstand the buoyancy of the pontoon; and a transmission member disposed under the set distance of the lower end of the pontoon which is in a state of being abutted against the damper At the side position, the weight of the pontoon is received when the pontoon is lowered, and the drain valve is moved downward. The toilet flushing water tank can open the drain valve when the air flap is closed. In this case, the buoyancy generated by the air in the air chamber is used to maintain the valve opening state. Therefore, the toilet flushing water tank can be made to have a large discharge amount of the washing water from the water tank main body because the opening of the drain valve is long. When the toilet water tank is subjected to the large cleaning, the drain valve having the buoyancy by using the air filled by the air chamber can be closed by moving downward in the direction of the transmission member that receives the weight of the float. Furthermore, the toilet flushing water tank can perform small washing by opening the air flap and the drain valve. That is, in the state where the air flap is opened, since the air in the air chamber has been discharged, the drain valve does not generate buoyancy. Therefore, only by using the buoyancy of the buoy to keep the drain valve open, the valve opening state of the drain valve is shortened, and the discharge of the washing water from the tank body is performed to a small extent. Cleaning. In this way, the toilet flushing water tank can be used as a hammer by one pontoon or as a function of the original pontoon, and the large washing and the small washing can be switched. Further, by changing the length of the transmission member that receives the weight of the float, it is possible to change the timing of the valve closing of the drain valve during the execution of the large purge. In other words, the amount of water discharged from the washing water during the large washing can be changed. 101103225 11 201237239 Therefore, the toilet washing tank of the second invention can be safely cleaned. ^亍大清洗和小再者' This toilet wash tank is sufficient because one of the required floats σ, so it can reduce the space occupied by the float in the water phase, so it can be miniaturized. The toilet flushing water tank of the present invention is a toilet washing water tank for supplying washing water to a flush toilet, characterized in that it comprises: a water tank body that stores washing water and has a drain port at the bottom. The drain valve opens and closes The first pull-up material is connected to the drain valve, and when the large-scale cleaning is performed to discharge a large amount of washing water from the drain port, the drain is pulled wide to open; the second pull-up material is connected The drain valve is configured to perform a small clearing material that discharges washing water that is less than the above-mentioned large washing from the drain port, pull the drain port upward to open the valve, and the rotating shaft is provided with a shaft portion and an arm portion; The shaft portion is rotated about the center of the car. The body of the water tank extends toward the water tank body, and has a connecting portion at the front end portion, and the connecting thorn connects the side of the two sides of the heart. In the above! The upper portion of the upper pull material is coupled to the upper portion of the second pull-up material; the arm portion is between the first pull-up material and the j second pull-up material that is suspended from the shaft portion The front end shaft extends downward and rotates with the rotation of the shaft portion. When the shaft portion is rotated in a direction of 10Π03225 12 201237239, the first pull-up material is pulled up, and if the shaft portion is rotated in the reverse direction, The second pull-up material is pulled up. Therefore, if the shaft is rotated in one direction, the arm pulls up the first pull-up material. If the shaft portion is rotated in the opposite direction, the second pull-up material is pulled up. In other words, the toilet water tank has an arm portion extending downward from the front end portion of the shaft portion between the first pull-up material and the second pull-up material, and the front end portion of the arm portion is hooked by rotating the shaft portion. The first pull-up material or the second pull-up material can be pulled up by one of the first pull-up material or the second pull-up material. In this way, since the toilet washing water tank does not need to be connected to the axial center of the shaft portion to be largely separated from the two sides of the shaft portion, it is not necessary to connect the joint portion from the shaft portion to the two sides. Set sideways. In other words, the second pull-up material and the second pull-up material can be arranged close to each other. Further, since the arm portion is formed to extend downward from the front end portion of the shaft portion, the connecting portion and the arm portion can be miniaturized, and the space occupied by the water tank body can be reduced. Therefore, the toilet washing water tank of the third invention can be miniaturized. A toilet flushing water tank according to a fourth aspect of the present invention is a toilet washing water tank that supplies washing water to a flush toilet. The utility model is characterized in that: a water tank body is provided, which stores washing water and has a drain port at the bottom; The water tank body is mounted on the water tank body and extends toward the water tank body; the upper pull material is coupled to the front end portion of the rotating shaft; and the drain valve opens and closes the drain port, and has the lower end of the pull-up material respectively connected The center of the water tank body is viewed from the front, and the center of the left and right direction is 101103225 13 201237239. When the washing handle is attached to the right handle of the right tank wall, the toilet material can be attached to the right mounting portion. Further, when the washing water phase is attached to the left handle of the left tank wall, the pull-up material can be connected to the mounting portion on the left side. Therefore, the toilet washing tank of the fourth invention can use the same drain valve regardless of whether the washing handle is the right handle size or the left handle size. Furthermore, the toilet flushing water tank can reduce the type of drain valve required and achieve a reduction in cost. [Embodiment] A preferred embodiment of the first invention will be described. In the first aspect of the invention, the force required to open the valve in order to pull up the air valve can be made smaller than the force required to open the valve in order to pull the drain valve upward. In this case, when the small cleaning is performed, the air flap is normally pulled up and the upper flap is opened, and the valve can be opened by pulling up the drain valve while the air flap is opened. The air flap of the first aspect of the invention may have an elastic member that imparts an elastic force toward the lower valve closing direction. In this case, when the toilet flushing water tank performs a small cleaning, after the drain valve is opened, the elastic force of the elastic member is used to make the drainage read. The air flap moves relatively quickly upwards, causing the air flap to automatically close the valve. Therefore, a prevents the water stop failure that occurs when the drain valve is closed. The elastic force of the component prevents the air in the air chamber from activating the air, and pushes it through the bullet to leak 101103225 14 201237239. Therefore, when the toilet washing water tank performs a large cleaning, the air in the air chamber can be used to generate buoyancy, and the washing water stored in the water tank body can be maintained by maintaining the valve opening state of the drain room for a long time. Discharged with a certain amount of water. Further, the pull-up material according to the first aspect of the invention may be constituted by a first pull-up material that is directly coupled to the drain valve and a second pull-up material that is coupled to the air shutter. In this case, the large purge can be performed by directly opening the drain valve by pulling up the first pull-up material. On the other hand, a small cleaning can be performed by pulling up the second pull-up material. Therefore, the toilet washing tank can be distinguished and switched to perform washing and small washing. Further, the pull-up material of the first aspect of the invention is coupled to the air shutter, and the air shutter may have a lock device that is locked in a closed state. In this case, if the upper pull material is pulled up while the lock device locks the air shutter to the closed state, only the drain valve is opened and a large purge can be performed. Further, if the pull-up material is pulled up while the lock device is not locked in the closed state, the drain valve can be opened after the air flap is opened, and small washing can be performed. Therefore, the toilet washing tank can be distinguished and switched to perform large cleaning and small cleaning. Further, the air chamber of the first invention may be provided at a lower portion of the drain. In this case, since the air chamber can be placed outside the tank body when the drain valve is closed, the size of the tank body can be reduced. Next, a preferred embodiment of the second invention will be described. 101103225 15 201237239 When the transmission member of the second invention can be separated from the above-described drain valve, the length of the transmission member can be easily changed. By changing the length of the transmission member, the time during which the weight of the pontoon is received and the drain valve is closed can be easily changed. Therefore, the toilet water tank can easily change the amount of water discharged from the washing water during the large cleaning. . The drain of the second invention may have a guide portion for guiding the pull-up material. In this case, the pull-up material can be prevented from being irregularly dumped in other directions. Therefore, the amount of water discharged from the washing water of the toilet washing water is not different from the set amount of water, and the amount of the set washing water can be appropriately discharged. Next, a preferred embodiment of the third invention will be described. The arm portion according to the third aspect of the invention may have an anti-bias portion that prevents the second pull-up material and the second pull-up material from being displaced outward from both side surfaces. In this case, the first pull-up material and the second pull-up material can be prevented from shifting outward. Therefore, the toilet flushing tank prevents the drain valve from being opened due to the inability of the arm to pull up the pull-up material. Next, a preferred embodiment of the fourth invention will be described. The mounting portion according to the fourth aspect of the invention may have a shape that is bilaterally symmetrical with respect to the left-right direction of the drain valve. In this case, when the washing handle is attached to the right tank wall to be the right grip gauge, or when the washing handle is attached to the left tank wall to be the left grip gauge, the front end of the rotating shaft and the opening and closing valve The relative positional relationship between the mounting portions is the same except for the left and right symmetry. Therefore, in any case of the right handle specification or the left handle specification, 101103225 201237239, the front end portion of the rotary shaft and the opening and closing valve mounting portion can be used with the pull-up material. In the same manner, the opening and closing valve can be opened and closed in the same manner during the washing operation. Next, the first and second embodiments in which the toilet washing water tanks of the second to fourth inventions are embodied will be described with reference to the drawings. <Example 1> Only the toilet bowl of the embodiment 1 is provided with a tank body 10 having an outer tank 12 and an inner tank 4 as shown in Fig. 1 .

The claw M2 is locked to the locking hole 15A and is connected to the lower portion of the valve portion 28. The switching device 46 operates in the following manner. If the air shutter 58 is closed and air is accumulated in the air chamber 50, When the flap valve 22 is opened, a large amount of washing water can be supplied from the toilet flushing water tank to the flushing toilet. On the other hand, if the air flap 58 is pulled up to open the valve, the washing water is washed. The inside of the casing 47 flows into the casing 47 from the inflow port 72, and flows into the air chamber 5 through the opening 57, so that the inside of the air chamber 50 is filled with the washing water. When the flap valve 22 is opened in this state, a small washing of a small amount of washing water from the toilet flushing water tank to the flush toilet can be performed. That is, by switching the air shutter 58 to switch the flap valve 22 to The specific principle of the switching is described later. The cylindrical body 74 as the transmission member transmits the downward force to the flap valve 22 by receiving the weight of the pontoon 84 to be described later. The flap valve 22 is moved downward toward 101103225 20 201237239. The cylindrical body 74 is attached to the ball chain 7 状态 in a state in which the small bead chain 7 插 is inserted inside. The guide portion 76 of the tubular body 74 is provided with a pair of guide plates 78 that face each other with the tubular body 74 interposed therebetween, and a tubular portion 8 that is provided on the lower side thereof. The tubular portion 8 is formed integrally with the upper wall portion 82 and the fitting portion 154 that protrudes downward from the upper wall portion 82. The insertion portion 154 is provided with a locking claw 156. On the other hand, the cylindrical wall 56 is provided with a locking hole 158 at a position corresponding to the locking claw 156. The guide portion 76 is attached to the cylinder wall % by inserting the fitting portion 154 into the inner side of the tubular wall % and locking the locking claw 156 to the locking hole 1S8. In this way, the guiding portion 76 is disposed on the flap valve 22. The barrel 74 can transmit a downward force to the flap valve 22 via the barrel 80 of the guide portion 76. The guide portion 76 allows the tubular body 74 to be inclined in the same direction as the oblique direction of the small-purchase bead chain 7〇. Further, the guide portion 76 prevents the cylindrical body % from being inclined in a direction orthogonal to the oblique direction of the small-purchase bead chain 70. That is, when the (four) 74 is inclined in the direction orthogonal to the inclination direction of the small-purity bead chain 7〇, the guide wall 78 abuts against the cylindrical body 74, so that the inclination can be prevented. The guide portions 76 are provided at the upper end portions of the guide walls 78 so as to open toward each other.

These guides 160 guide the cylinder 74 between the pair of guide walls 78. The S float 84 is annular in shape as shown in Fig. 1 and Fig. 2, and has a closed cavity portion 86 therein. This hollow portion 86 is kept air. Further, the pontoon has a perforation at the center. The pontoon 84 is inserted in the state in which the chain for small cleaning = 101103225 21 201237239 is inserted into the perforation (10) in the vertical direction. The pontoon 84 is movable along the bead chain 70 for small cleaning toward the two ball. The ball chain 70 for slip cleaning under U is at a predetermined height position (stopper)%. This stop 9〇 can be adjusted up and down to the position of the small main 疋 止 珠 7 chain 7G. The circular locking portion 162 having a fixed shape and a locking portion is formed by an insertion hole = 162 and a 162 degree fixing portion 122 provided at the center portion of the stopper 9 . The perforation 12 can hold the small cleaning and the connecting material 40 of the card 70. The bead chain of the month's end is formed at the lower end of the tubular body 74 and abuts against the guide portion 76. The space between the upper end of the body 74 and the load 90 is formed to be smaller than the float. In other words, the tubular body 74 is provided on the lower side of the pontoon 8 that is in contact with the stopper 90. Therefore, the pontoon 84 can be moved away from the set end and the load %, and moved up along the small ball cylinder 74 for cleaning. The rotation axis 92 connected to the cleaning handle 94 is extended as shown in FIG. The rotating shaft 92 has a shaft portion % and a portion of the net handle 94 and (4) a shaft 92 as shown in Fig. 5, and the material 14 = is mounted on the tank wall 18. The mounting member 98 has an externally threaded portion _, and is fixed to the tank wall a by screwing the threaded portion 1 into the nut 102. g is a portion of the shaft portion 96 of the rotating shaft 92 having a corner portion provided outside the front end portion, and a fitting portion 104 provided at the front end portion of the comparative portion G4 and having 101103225 22 201237239 elasticity. . The washing handle 94 has an inner fitting portion 1〇8 corresponding to the angle of the rear portion of the rear portion 104b, and a desired insertion hole 11G which interferes with the fitting portion 1〇6. The shaft portion 96 is configured such that the outer portion 1 () 4 is intended to be inserted into the inner portion 1 〇 8 of the washing handle 94, and the bulging portion 1 〇 635 is fitted into the insertion hole no ' Handle 94. Therefore, the vehicle-part 96 is fixed to the washing handle 94 in the direction of the shaft and the direction of rotation. Further, the shaft portion 96 is inserted through the insertion hole provided in the center of the attachment member 98, and linearly extends toward the tank body (4). The vehicle-part 96 and the arm portion 114 extending downward from the other curved front end portion are formed as a body. The arm portion m is longitudinal, that is, extends vertically downward in a normal state. The arm portion 114 can pass through the _1G2. The size of the hole. The car is also the same as the Ministry 96. (4) % is as shown in Fig. 7, 'there is a portion of the m-bead chain 36 that is attached to the other end of the curved portion, and the upper portion of the m-bead chain 36 is attached to the side of the cuff And the second connecting portion 118 that connects the small cleaning bead chain 70 to the other side. The first connection, the (7) 116, and the second connection portion 118 are not provided in FIGS. 6(A), (c), and FIG. The insertion hole U0 in which the connecting material 4〇 of the ball chain 36, 7〇 is inserted in the vertical direction, and the ball 38A (refer to FIG. 8) and the lower side ball 38B which are inserted into the upper side of the joining material are engaged. Engagement part. Bead key strips 36, 7 (M is inserted into the tow hole 12〇 by the connecting material 4〇, and the upper side bead emblem and the lower side bead are engaged with the engaging part 122 The first connecting portion 116 or the second connecting portion 118 is connected to the 101103225 23 5 201237239. The large cleaning bead chain 36 connected to the first connecting portion 116 and the small cleaning device connected to the second connecting portion 118 are used. The ball chain 70 is in a state of being suspended from both sides of the axial center of the shaft portion 96. The arm portion 114 has a vertical downward direction from the intermediate position between the first connecting portion 116 and the second connecting portion 118. The plate-shaped arm body 124 extends to the lower side of the set distance. The arm body 124 does not fix the ball chain 36 for large cleaning and the ball key bar 70 for small cleaning. Therefore, the ball for large cleaning is used. The key strip 36 and the small-purchase bead chain 70 are not restrained by the arm body 124 in normal times. Normally, the large-purchase ball chain 36 is suspended from the first joint portion 116 along the arm body 124, and is small. The ball chain 70 for cleaning also hangs down the arm body 124 from the second connecting portion 118. When the washing handle 94 is rotated counterclockwise, the shaft portion 96 and the arm portion 114 rotate in the same direction. The front end portion 124A of the arm body 124 hooks the ball string 36 for large cleaning, and pulls up the ball chain 36 for large cleaning. The ball chain 36 for large cleaning is directly (not via the air valve 58). That is, the valve opening force is not applied to the air shutter 58. The flap valve 22 is pulled up to open the valve. Therefore, it is possible to perform a large cleaning in which the washing water in the tank body 10 is largely discharged. At this time, the ball for small washing is used. The chain 70 is not pulled up by the arm body 124, but remains sagging from the second joint 118 When the washing handle 94 is rotated in the clockwise direction, the shaft portion 96 and the arm portions 101103225 24 201237239 114 are rotated in the same direction. Thus, the front end portion 124A of the arm body 124 is hooked for small cleaning. The ball chain 70 pulls up the ball chain 70 for small cleaning. The ball chain 70 for small cleaning causes the air valve 58 to pull up against the spring force of the spring 60 to open the valve. The force required to open the valve when the flap valve 22 in the closed state is set against the water pressure of the washing water in the tank body 1 is small. Therefore, if the ball chain 70 for small cleaning is pulled up, the air shutter 58 is first pulled up to open the valve, and then the flap valve 22 is pulled up to open the valve in a state where the air flap 58 is opened. Thus, when the flap valve 22 is opened, a small amount of washing water which is less than the large washing is discharged from the tank body 1 and a small washing can be performed. At this time, the ball chain for large cleaning is not pulled up by the arm body 124, and is kept in a state of being suspended from the first connecting portion 1丨6. As shown in Figs. 6 and 7, the arm portion 114 has a pair of plate-shaped guide walls 128 extending downward from the first connecting portion 116 and the second connecting portion 118 and facing each other on both sides of the arm body 124. The guide walls 128 are made of a third anti-offset portion 130 that prevents the large-purchase bead chain 36 from being displaced outward from both sides of the arm body 124, and a ball-proof chain 70 for preventing small cleaning from the arm body 124. The second deflecting portion 132 whose both side surfaces are offset outward is formed. The bead chain 36 for large cleaning hangs down on the rear side of the arm body 124 when the tank body 1 is viewed from the front. The % of the ball chain for large cleaning is hooked up to the end of the body 124. At this time, the bead chain 36 for large cleaning abuts against the inner side surface of the guide wall 128, and the first anti-biasing portion 130 prevents the large cleaning bead chain 38' of the 101103225 25 201237239 from falling along the arm body 124. It is offset from the hanging position in the left-right direction. Furthermore, Xiaoqing Putian

處於閉閥狀態（參照圖11(1))。於此狀態下，浮筒84係在沉 沒於水中的位置處，利用浮力朝上方抵接於擋止90。又， 設置於瓣閥22的空氣室50内部係充滿空氣。 若由此狀態將洗淨把手94朝執行大清洗的方向，即逆時 針方向旋轉，臂部114就會朝相同方向旋轉。如此一來，臂 本體124的前端部124A就會勾住從大清洗用圓珠鏈條36 的第1連結部116離開設定距離的下方之部位，將圓珠鏈條 36僅上拉所設定的距離。此時，圓珠鏈條36係一邊被靠近 溢流管24側拉扯一邊上拉。藉此，如圖11 (II)所示，使瓣 閥22利用圓珠鏈條36被直接上拉而開閥。若瓣閥22到達 所設定的最大開閥位置，就會藉由未圖示之停止構件阻止更 進一步的旋轉。開閥的瓣閥22係利用沉沒於水中之狀態的 浮筒84所產生的浮力、與空氣室50的浮力，維持為開閥之 狀態，而將水箱本體10内的洗淨水從排水口 20排出。 隨著水箱本體10内洗淨水之排出，水箱本體10内的水位 W會下降。然後，如圖12(111)所示，在水位W從浮筒84 的上端下降一定距離後，浮筒84本身之重量與浮力就會達 成平衡之狀態，然後，浮筒84係隨著水位W之下降一起沿 圓珠鏈條70朝下方移動。 於此狀況下，空氣室50係充滿空氣，持續地產生浮力作 用。所以，如圖12(IV)所示，即便浮筒84隨水位W之下降 101103225 28 201237239 而朝下方移動’瓣闕22亦保持為開閥之狀態。浮筒84離開 擋止90並沿著小清洗用之圓珠鏈條7〇朝下方移動。 浮筒84係在離開擋止90並下降一定距離後，如圖ι3(ν；) 所示’抵接於筒體74的上端。若水位w進一步下降，則浮 筒84的浮力就會減少’而使施加於筒體74的浮筒84之重 量增加。 若浮筒84將筒體74朝下方按押之力大於空氣室5〇的浮 力，則瓣閥22便無法維持開閥之狀態。然後，隨著水位W 之下降，瓣閥22開始閉閥，最終將完全閉閥。藉此，停止 來自排水口 20的洗淨水之排出。 另一方面，若使洗淨把手94朝執行小清洗的方向，即， 順時針方向旋轉，臂部114就會朝相同方向旋轉。如此一 來，臂本體124的前端部124A就會勾住從小清洗用之圓珠 鏈條70的第2連結部118離開設定距離的下方之部位將圓 珠鏈條70僅上拉所設定之距離。此時，圓珠鏈條70係一邊 被離開溢流管24之側被扯一邊上拉。 在瓣閥22為閉閥之狀態下，使切換裝置46的空氣活門 58反抗彈簧60的彈力朝上方被上拉而開闊。如此一來，空 氣室50係使上端開口 57成為開放之狀態，利用通過流入口 72流入的洗淨水充滿水箱本體10内。 若空氣活門58進一步被上拉，藉由小清洗用之圓珠鏈條 70的上拉力就會傳遞至瓣閥22而將瓣閥22開閥。離開閥 101103225 29 201237239 座、的辦閥22係利用彈簧60的彈力，相對於空氣活 迅速地朝上方移動。即，—__空氣活門Μ在 迅=恢復為閉間之狀態。然後，在該狀態下瓣閱22會藉: 小/月洗用之圓珠鏈條7G被上拉，然後到達最大 照圖 14(1))。 藉由瓣閱22的開閥，水箱本體1〇内的洗淨水被排出，水 位w下降。如圖14(π)所示，若浮筒以的上部成為位於些 微從水面露㈣位置，就會使浮筒84本身之重量與浮力: ^達成平衡的狀態。㈣，Μ於執行大清洗時，因為在小 清洗執行時，空氣室50内充滿洗淨水，因此空氣室5〇不會 產生浮力。所以，若隨著水位W之下降而使浮筒84朝下方 移動’瓣閥22便會暫時縮小閥開度，如圖15(111)所示，最 終將會坐在閥座44上而完全閉閥。 在此期間，因為空氣室5〇並不會產生浮力，因此浮筒料 係維持抵接於擋止90的狀態，即維持在與筒體74之間相隔 一定距離陳態下，隨水位W之下降—起朝下方移動。所 以’當執行小清洗時，從瓣閥22完全開閥起至開始閉閥的 時間較短，，小清洗時純於大清洗在㈣⑽段便開始 瓣闕22的閉間而閉闕。所以，在小清洗時可執行洗淨水之 排出水量較少的洗淨。 如以上說明，此便器洗淨水箱所必需的浮筒只要！<固便足 夠，可減少浮筒84纟水箱本體1〇内所佔的空間。因此可 101103225 30 201237239 使水箱本體ίο成為小型。 再者，此便器洗淨水箱係藉由使旋轉軸92朝逆時斜方 旋轉，利用從旋轉軸92下垂的大清洗用之圓珠鏈條％，^ 不對空氣活門58賦予開閥力就能直接將瓣閥22上妆而$ 閥。此時，藉由空氣室50内充滿的空氣所產生之浮力，開 •發揮維持瓣閥22為開閥狀態的作用。所以，瓣閥22 可 狀態會變長，而使儲存於水箱本體1〇内的洗淨水大量 出，便可執行大清洗。 惠掷 再者，此便器洗淨水箱係藉由使旋轉軸92朝順時斜方 旋轉，將從旋轉軸92下垂的小清洗用之圓珠鏈條7〇上杈° 首先可開啟空氣活門58，然後在使空氣活門58為開閩之 態下使瓣閥22開閥。此時，因為空氣室50流入有水箱本、 10内的洗淨水’因此不會產生浮力。所以，僅由在4、 凊洗 用之圓珠鏈條70安裝之浮筒84所產生之浮力作用於鱗^ 22 ’所以使瓣閥22的開閥狀態變短，而使儲存於水箱本發 1〇内的洗淨水之排出量變少，便可執行小清洗。 所以，實施例1的便器洗淨水箱可使排出之洗淨水的水量 不同’俾可執行大清洗與小清洗。尤其，此便器洗淨水箱並 不會受到對圓珠鏈條上拉之操作量大小的影響，而是根據旋 轉軸92的旋轉方向不同，便可依照意願安定地執行大清洗 與小清洗。 再者，此便器洗淨水箱由於使作為傳遞構件的筒體74構 101103225 31 201237239 成與_ 22為不同.之個體，因此藉由變更筒體％的長度， 便可輕易地變更承受浮筒84之重量而使辦閥22開始閉闕的 時期。因此’此便料淨水射㈣地變更執行大清洗時所 排出洗淨水的水量。 再者，此便器洗淨水箱係因為切換裝置46具有對空氣活 門58朝下方之關方向賦傾力的彈簧⑼，所以當執行小 清洗時，在瓣閥22開閥後，空氣活門％就會自動地閉闕。 因此，可防止在其後當關22 _時之止水不良。又，利 用彈簧60的彈力，可防止空氣室5()内的空氣將空氣活門 58上推而漏出。所以，此便11洗淨水箱當執行大清洗時， 可利用空氣至50内的空氣產生浮力而維持瓣閥22較久的開 閥狀態，俾可將儲存於水箱本體_洗淨水以—定的安定水 量排出。 再者，此便器洗淨水箱係因為將空氣室50設置於瓣閥22 的下部，因此可將空氣室50配置於内水箱14外，俾可實現 水相本體10的小型化。 再者，此便器洗淨水箱係使從第1連結部116與第2連結 β 118之中間位置離開至設定距離的下側為止朝垂直下方 (伸之臂本體124之前端部124Α，依照旋轉方向的不同， 勾住大清洗用之圓珠鏈條36或小清洗用之圓珠鏈條70中之 4者而上拉所以，第1連結部116與第2連結部118不 需要設置為朝左右大幅地離開，而是可相靠近地設置。又， 101103225 32 201237239 因為臂部114係從軸部96的前端部朝下方延伸所形成，因 此可將第1連結部116、第2連結部118、及臂部114小型 化俾可縮小此等在水箱本體1 〇内所佔據之空間。 所以，實施例1的便器洗淨水箱可實現小型化。 再者，臂部Π4係可穿過螺帽1〇2的中心孔。所以，使臂 部114與軸部96成為一體化，俾可減少零件之數量，而使 成本較為價廉。 再者，因為此便器洗淨水箱係設有第1防偏部13〇及第 防偏部132，因此可防止大清洗用之圓珠鏈條36咬】主 用之圓珠鏈條70從由臂本體124下垂的狀態朝外側偏 即’此便器洗淨水箱可防止因臂本體124的前蠕部12夕° 法將大清洗用之圓珠鏈條36或小清洗用之圓珠鍵條％ *''' 上拉，所發生之洗淨不良。 ' 再者，此便器洗淨水箱係如圖16所示，可對應將、先、爭 手94安裝於左側水箱壁18的左把手規格。於此情況時 瓣閥22所設置的左側第1安裝部42L，安裝有從旋轉軸^ 下垂的大清洗用之圓珠鏈條36之下端。小清洗用之 ' 條70係與右把手規格相同地’將下端連結於位於瓣閱^ 左右方向的t心位置、且位於水箱本體1〇左右方向之中、 位置的瓣閥22之第2安裝部68。 左把手規格的便器洗淨水箱係相對於右把手規格的便

不左把手規格的洗淨犯手94、旋轉軸92係相同之物品。 如此’此便器洗淨水箱係將洗淨把手94安裝於右侧水箱 壁18的右把手規格時，在右側的第丨安裝部42R安裝著大 ’月洗用之圓珠鏈條36。又，此便器洗淨水箱係將洗淨把手 94女襄於左侧水箱壁18的左把手規格時，在左側的第j安 裝部42L安裝大清洗用之圓珠鏈條36。而且，藉由在瓣閥 22左右方向之中心位置的第2安裝部68，安裝小清洗用之 圓珠鏈條70，使用相同的瓣閥22可對應右把手規格與左把 手規格之任一者。所以，可減少必要的瓣閥種類，俾可實現 成本降低。 <實施例2> 實施例2的便器洗淨水箱係如圖17所示，僅具有1條當 作上拉材用的圓珠鏈條35。此圓珠鏈條35係連接於空氣活 門58 ’並安裝有未圖示之浮筒84。此便器洗淨水箱係具有 將空氣活門58鎖定為閉閥狀態的鎖定裝置164。其他之構 造與實施例1相同，相同的構造便賦予相同的元件符號’並 省略詳細之說明。 10Π03225 34 201237239 此鎖定裝置164若使洗淨把手94朝執行大清洗的方向， 即逆時針方向旋轉，便將空氣活門58鎖定為閉間狀雖、而阻 止開閥。另一方面，此鎖定裝置164若使洗淨把手％ |月執 行小清洗的方向，即順時針方向旋轉，便容許空氣活門％ 的開閥。 鎖定裝置164係設置於空氣活門58的轴部66，其具備 有：突起166、溝168、及抵接部170 ;該突起166係朝上 方為尖銳形狀。該溝168係設置於殼體47 ;該抵接部17〇 係藉由使突起166朝上方抵接，‘阻止突起166、即☆氣、、舌 門58朝上方移動。 若使洗淨把手94朝執行大清洗的方向、即逆時針方向旋 轉，則如圖17(B)所示，突起166就會抵接於抵接部17〇而 使空氣活門58成為鎖定狀態，俾阻止空氣活門58的開閥。 所以可在不對空氣活門％賦予開閥之力的情況下使瓣闊 22開閉。於此情況時，空氣室5()係保持充滿空氣之狀態並 產生浮力所以’便器洗淨水箱係瓣閥22的開閥狀態會變 長俾可將儲存於水箱本體1〇内的洗淨水大量地排出，便 可執行大清洗。 再者，若使洗淨把手94朝執行小清洗的方向 、即順時針 方向旋轉’則如圖17㈧所示，因為圓珠鏈條％會一邊被 離開溢流管24之側拉扯—邊上拉，因此使突起166進入溝 之側並溝166朝上方相對移動。所以，使空氣活門 101103225 35 201237239 5 8開閥，然後在空氣/舌門58為開閥之狀態下使瓣閥22開 閥。於此情況時，因為空氣室50内流入有水箱本體1〇内的 洗淨水，因此不會產生浮力。所以，便器洗淨水箱係瓣閥 22的開閥狀態會縮短，而使儲存於水箱本體1 〇内的洗淨水 之排出量變少’便可執行小清洗。 本發明並不偏限於利用上述敘述與圖式所說明的實施

bead chain 70 is used to sag the front side of the arm body D 4 when the tank body 10 is viewed from the front. This small cleaning bead chain 70 is also pulled up by hooking the front end portion 124A of the arm body 1 and the spring. At this time, the second anti-bias portion 132 is prevented from being abutted against the inner side surface of the guide wall 128 by the small bead/first use bead key strip 7G, and the second anti-bias portion 132 can prevent the small cleaning of the body 124 from sagging. The ball chain 70' is offset from the hanging position toward the left and right. 2 The type and size of the main body 10, etc., the first connecting portion 11 (4) ^ Ρ 8 and the mounting position of the valve 22 are in a dangerous shape toward the shaft portion 96. In this case, if the first deflecting prevention portion 130 and the second deflecting prevention portion 132 are not provided by the guide wall 12, the bead chain 36 for large cleaning is present as shown in Fig. 10 or In the small cleaning, the bead chain, 7〇 will be deflected outward from the position along the arm body 124. The second right forms this state, and even if the arm portion 114 rotates, the end of the arm is | Ρ124Α can't hook the bead chain %, 7〇, but can't pull the other bead key 36, 7G. Therefore, the m-th apex portion 13 〇 and the anti-bias portion 132 are used to prevent this state. This is the first time. The P 114 has the third anti-biasing portion 134 and the fourth anti-biasing portion 136; the round-three anti-biasing portion 134 is left to sag in the rotation _, and the key strip 36 is offset from the first connecting portion 116 to the outside for the large cleaning. The fourth anti-biasing portion is a small ball-shaped key bar 101101225 26 201237239 which is prevented from being dropped on the side of the rotation, and is offset from the second connecting portion 118. The third anti-biasing portion 134 and the fourth anti-biasing portion 136 have a lid portion 138 and a slit 140'. The body portion 138 is bent from the first connecting portion n6 or the second connecting portion 118 toward the guide wall 128. The slit 140 is connected to the insertion hole 120 of the first connection portion 116 or the second connection portion 118 and is provided in the lid portion 138. As shown in FIG. 8, the lid body 4 138 is formed to be a round ball chain 36 for large cleaning attached to the first connecting portion 116 and the second connecting portion 118, and a lower side of the ball key strip 70 for small cleaning. Wang Zhu handed the shape from the outside. When the bead chain 36 for large cleaning is attached to the second coupling portion 116 and the small cleaning bead chain 7 is attached to the second coupling portion u8, as shown in Fig. 9, the respective bead chains 36, 7 The splicing material 4 is passed through the slit 14 and inserted into the insertion hole 12G. At this time, 'the first one is formed so that the bead 38B of the bead 38B of the lower side of each of the bead chains 36 and 7 is closed, and in this state, the splice member 4 〇 and the upper side bead are formed along the slit 140. The 38A moves toward the i-th link 116 or the second link 118 side. The lid portion 138 is provided with a guide portion 144 having an inclined shape for guiding the splice member 40 toward the slit 14A at the lower end. As shown in FIGS. 5 to 7, the shaft portion 96 has a reinforcing rib 142 extending from the upper end of the arm portion 114 and continuing to the arm body 124. Next, the toilet washing operation of the toilet washing tank having this configuration will be described. 101103225 27 201237239 As shown in Fig. 5, when the washing handle 94 is in the neutral position, the flap valve 22 is in a closed state (refer to Fig. 11 (1)). In this state, the pontoon 84 is at a position where it sinks in the water, and abuts against the stopper 90 upward by buoyancy. Further, the inside of the air chamber 50 provided in the flap valve 22 is filled with air. If the washing handle 94 is rotated in the direction in which the large washing is performed, that is, in the counterclockwise direction, the arm portion 114 is rotated in the same direction. As a result, the front end portion 124A of the arm main body 124 is hooked away from the first connecting portion 116 of the large-cleaning ball chain 36 at a position below the set distance, and the ball chain 36 is pulled up only by the set distance. At this time, the ball chain 36 is pulled up while being pulled toward the side of the overflow pipe 24. Thereby, as shown in Fig. 11 (II), the flap valve 22 is directly pulled up by the ball chain 36 to open the valve. If the flap valve 22 reaches the set maximum valve opening position, further rotation is prevented by the stop member (not shown). The valve valve 22 that opens the valve is maintained in a valve-open state by the buoyancy generated by the float 84 in a state of being submerged in water, and the buoyancy of the air chamber 50, and the washing water in the tank body 10 is discharged from the drain port 20. . As the washing water in the tank body 10 is discharged, the water level W in the tank body 10 is lowered. Then, as shown in Fig. 12 (111), after the water level W is lowered by a certain distance from the upper end of the pontoon 84, the weight of the pontoon 84 itself and the buoyancy force are balanced, and then the pontoon 84 is lowered along with the water level W. Moves downward along the bead chain 70. In this case, the air chamber 50 is filled with air to continuously generate buoyancy. Therefore, as shown in Fig. 12 (IV), even if the float 84 moves downward with the water level W falling 101103225 28 201237239, the flap 22 remains in the open state. The float 84 leaves the stop 90 and moves downward along the small bead chain 7〇. The pontoon 84 abuts against the upper end of the cylinder 74 as shown in Fig. ι3 (ν;) after leaving the stopper 90 and descending by a certain distance. If the water level w is further lowered, the buoyancy of the float 84 is reduced, and the weight of the float 84 applied to the cylinder 74 is increased. If the pontoon 84 pushes the cylinder 74 downward, the force is greater than the buoyancy of the air chamber 5, the flap valve 22 cannot maintain the valve open state. Then, as the water level W drops, the flap valve 22 begins to close and eventually closes completely. Thereby, the discharge of the washing water from the drain port 20 is stopped. On the other hand, when the washing handle 94 is rotated in the direction in which the small washing is performed, that is, in the clockwise direction, the arm portion 114 is rotated in the same direction. As a result, the distal end portion 124A of the arm body 124 is hooked away from the second connecting portion 118 of the small cleaning bead chain 70 by a distance set below the set distance to pull the ball chain 70 up only. At this time, the bead chain 70 is pulled up while being pulled away from the side of the overflow pipe 24. In a state where the flap valve 22 is closed, the air shutter 58 of the switching device 46 is pulled up against the elastic force of the spring 60 to be widened. In this manner, the air chamber 50 is in an open state in which the upper end opening 57 is opened, and the inside of the water tank main body 10 is filled by the washing water flowing in through the inflow port 72. If the air flap 58 is further pulled up, the pull-up force of the ball chain 70 for small cleaning is transmitted to the flap valve 22 to open the flap valve 22. The valve 22 of the seat 101103225 29 201237239 is moved upward by the spring force of the spring 60 with respect to the air. That is, the —__ air flap Μ is restored to a closed state. Then, in this state, the flap 22 will be borrowed: The small/monthly washed bead chain 7G is pulled up and then reaches the maximum photograph (Fig. 14(1)). By opening the valve of the flap 22, the washing water in the tank body 1 is discharged, and the water level w is lowered. As shown in Fig. 14 (π), if the upper portion of the pontoon is located slightly from the surface of the water surface (four), the weight of the pontoon 84 itself and the buoyancy force are obtained: (4) When the large cleaning is performed, since the air chamber 50 is filled with the washing water during the small washing execution, the air chamber 5 does not generate buoyancy. Therefore, if the float 84 is moved downward as the water level W drops, the flap valve 22 will temporarily reduce the valve opening degree, as shown in Fig. 15 (111), and finally will sit on the valve seat 44 and completely close the valve. . During this period, since the air chamber 5 does not generate buoyancy, the float material maintains a state of abutting against the stopper 90, that is, maintained at a certain distance from the cylinder 74, and decreases with the water level W. - Start moving downwards. Therefore, when the small cleaning is performed, the time from the full opening of the flap valve 22 to the start of the valve closing is short, and the small washing is purely in the large cleaning, and the closing of the flap 22 is started in the (4) (10) section. Therefore, in the case of small washing, it is possible to perform washing with a small amount of discharged water. As explained above, this toilet needs to float the water tank as long as it is! <Solid enough to reduce the space occupied by the pontoon 84 in the tank body 1〇. Therefore, 101103225 30 201237239 makes the water tank body ίο small. Further, the toilet flushing water tank is rotated obliquely in the reverse direction by the rotation shaft 92, and the large-purity ball chain % sagged from the rotating shaft 92 can be directly applied to the air shutter 58 without the valve opening force. Place the flap valve 22 on the makeup and $ valve. At this time, the buoyancy generated by the air filled in the air chamber 50 acts to maintain the valve valve 22 in the valve open state. Therefore, the flap valve 22 can be made longer, and the washing water stored in the tank body 1b can be largely discharged, and the large washing can be performed. In addition, the toilet flushing water tank is rotated by the rotation axis 92 obliquely, and the small cleaning bead chain 7 that hangs from the rotating shaft 92 is first turned on. First, the air shutter 58 can be opened. The flap valve 22 is then opened in a state where the air flap 58 is opened. At this time, since the air chamber 50 flows into the water tank 10, the washing water in the water tank 10 does not generate buoyancy. Therefore, only the buoyancy generated by the pontoon 84 mounted on the beading chain 70 for scouring acts on the scale 22', so that the valve opening state of the flap valve 22 is shortened, so that the storage is in the water tank. The amount of washing water inside is reduced, and a small washing can be performed. Therefore, the toilet washing water tank of the first embodiment can make the amount of water discharged from the washing water different, and can perform large washing and small washing. In particular, the toilet washing tank is not affected by the amount of operation of the bead chain pulling up, but depending on the direction of rotation of the rotating shaft 92, it is possible to perform large cleaning and small cleaning as desired. In addition, since the toilet flushing water tank is made of a different body of the cylindrical body 74101103225 31 201237239 as a transmission member, the pontoon 84 can be easily changed by changing the length of the cylinder. The weight causes the valve 22 to begin to close. Therefore, the amount of water discharged from the washing water during the large cleaning is changed by the net water spray (four). Furthermore, since the switching device 46 has a spring (9) for biasing the air shutter 58 downward, when the small cleaning is performed, after the flap valve 22 is opened, the air shutter % is Automatically closed. Therefore, it is possible to prevent the water from being stopped when it is turned off 22 _. Further, the elastic force of the spring 60 prevents the air in the air chamber 5 () from pushing up and leaking the air shutter 58. Therefore, when the 11-cleaning water tank is subjected to large cleaning, the air can be used to generate buoyancy from the air in the air to maintain the valve valve 22 for a longer period of time, and the water can be stored in the water tank body _ washing water to determine The steady water volume is discharged. Further, since the toilet flushing water tank is provided in the lower portion of the flap valve 22, the air chamber 50 can be disposed outside the inner water tank 14, and the water phase main body 10 can be miniaturized. Further, the toilet washing water tank is vertically downward from the intermediate position between the first connecting portion 116 and the second connecting β 118 to the lower side of the set distance (the front end portion 124 of the arm main body 124 is extended, according to the rotation direction In addition, the first connecting portion 116 and the second connecting portion 118 do not need to be provided to largely separate from the left and right, so that the four of the large-beaded bead chain 36 or the small cleaning bead chain 70 are pulled up. In addition, 101103225 32 201237239 Since the arm portion 114 is formed to extend downward from the front end portion of the shaft portion 96, the first connecting portion 116, the second connecting portion 118, and the arm portion can be provided. The miniaturized crucible can reduce the space occupied by the water tank body 1 。. Therefore, the toilet washing water tank of the first embodiment can be miniaturized. Further, the arm Π 4 can pass through the nut 1 〇 2 Therefore, the arm portion 114 and the shaft portion 96 are integrated, so that the number of parts can be reduced, and the cost is relatively low. Moreover, since the toilet washing water tank is provided with the first anti-biasing portion 13 And the anti-bias portion 132, thereby preventing the circle for large cleaning The chain 36 bite] the main bead chain 70 is biased outward from the state in which the arm body 124 is suspended, and the toilet washing tank can prevent the ball from being cleaned by the front portion 12 of the arm body 124. Chain 36 or small cleaning ball key bar % *''' is pulled up, and the cleaning is not good. 'Moreover, this toilet washing water tank is shown in Figure 16, which can correspond to the first, the first, the competition 94 is attached to the left handle of the left tank wall 18. In this case, the left first mounting portion 42L of the flap valve 22 is attached to the lower end of the large cleaning bead chain 36 which is suspended from the rotating shaft ^. The second mounting portion 68 of the flap valve 22 that is positioned at the t-center position in the left-right direction of the valve body and in the left-right direction of the tank body 1 is the same as that of the right-hand grip. The toilet water tank of the left-handle type is the same as the right-hand-washing water tank, and the direction of the rotating shaft 92 is opposite to the left and right. Moreover, the bead chain 36 of the main rabbit 101103225 33 201237239 is connected to the second. The connecting portion 118 and the bead chain 7 for small cleaning are connected to the first The connecting portion 116 can thereby perform a large cleaning by rotating the cleaning material 94 in the clockwise direction as viewed from the left side of the tank body ι, and performing a small cleaning by rotating in the counterclockwise direction. The washing handle 94, the rotating shaft 92, and the washing hand 94 and the rotating shaft 92 of the left handle size shown in Fig. 16 are the same items. Thus, the toilet washing tank will be washed. When the handle 94 is attached to the right handle of the right tank wall 18, a large 'moon wash bead chain 36 is attached to the right second mounting portion 42R. Further, the toilet washing tank will wash the handle 94 female. When the left handle of the left tank wall 18 is specified, the bead chain 36 for large cleaning is attached to the j-th mounting portion 42L on the left side. Further, the ball chain 70 for small cleaning is attached to the second attachment portion 68 at the center of the flap valve 22 in the left-right direction, and the same flap valve 22 can be used to correspond to either the right handle specification or the left handle specification. Therefore, the number of flap valves necessary can be reduced, and the cost can be reduced. <Example 2> The toilet washing water tank of the second embodiment has only one bead chain 35 as a pull-up material as shown in Fig. 17 . This bead chain 35 is connected to the air shutter 58' and is attached with a float 84 (not shown). The toilet flushing water tank has a locking device 164 that locks the air flap 58 to a closed state. The other configurations are the same as those in the first embodiment, and the same configurations are denoted by the same reference numerals and the detailed description is omitted. 10Π03225 34 201237239 When the cleaning device 94 rotates the washing handle 94 in the direction in which the cleaning is performed, that is, in the counterclockwise direction, the air shutter 58 is locked in the closed state to prevent the valve from being opened. On the other hand, if the locking device 164 rotates the washing handle % | month to perform the direction of small washing, that is, clockwise rotation, the opening of the air shutter % is allowed. The lock device 164 is provided on the shaft portion 66 of the air shutter 58 and includes a projection 166, a groove 168, and an abutting portion 170; the projection 166 has a sharp shape toward the upper side. The groove 168 is provided in the casing 47. The abutting portion 17 is brought into contact with the projection 166 upward, and the projection 166 is prevented from moving upward. When the washing handle 94 is rotated in the direction in which the large washing is performed, that is, in the counterclockwise direction, as shown in FIG. 17(B), the projection 166 abuts against the abutting portion 17A, and the air shutter 58 is locked.俾 Prevents the valve opening of the air flap 58. Therefore, the valve width 22 can be opened and closed without giving the valve opening force to the air valve %. In this case, the air chamber 5 () is kept in a state of being filled with air and buoyancy is generated, so that the valve opening state of the toilet tank valve 22 is lengthened, and the washing water stored in the tank body 1 can be stored. A large amount of discharge can be performed to perform a large cleaning. Further, if the washing handle 94 is rotated in the direction in which the small washing is performed, that is, in the clockwise direction, as shown in Fig. 17 (A), since the ball chain % is pulled up while being pulled away from the side of the overflow pipe 24, Therefore, the projection 166 is brought into the side of the groove and the groove 166 is relatively moved upward. Therefore, the air valve 101103225 35 201237239 5 8 is opened, and then the flap valve 22 is opened in a state where the air/tongue 58 is opened. In this case, since the washing water in the tank body 1 is poured into the air chamber 50, buoyancy does not occur. Therefore, the valve opening state of the toilet flushing water tank valve 22 is shortened, and the discharge amount of the washing water stored in the tank body 1 is reduced.
