Description

本発明は、便器の洗浄に用いる洗浄水を貯水しておく便器洗浄タンクに関するものであり、具体的には、フラッパータイプ排水弁を備えた洗浄水タンク装置に関する。   The present invention relates to a toilet flushing tank for storing flush water used for flushing toilet bowls, and more specifically to a flush water tank apparatus provided with a flapper type drain valve.

従来、水洗便器に洗浄水を供給するフラッパータイプ排水弁を備えた洗浄水タンク装置は、洗浄水を貯留するタンク本体と、タンク本体の底部に配設した排水口を開閉するフラッパー弁と、前記フラッパー弁を軸支する軸部と、前記フラッパー弁を開弁操作するための開弁操作装置とこのフラッパー弁を連繋する引き上げ部材とから構成されている。（例えば、特許文献１参照）   Conventionally, a flush water tank apparatus provided with a flapper type drain valve that supplies flush water to a flush toilet includes a tank body that stores flush water, a flapper valve that opens and closes a drain port disposed at the bottom of the tank body, It comprises a shaft portion that pivotally supports the flapper valve, a valve opening operation device for opening the flapper valve, and a lifting member that links the flapper valve. (For example, see Patent Document 1)

上記特許文献１においては図７に示すように、引き上げ部材１３０ｂはフラッパー弁１２１の略中心位置に連結され、開弁操作装置としての操作ハンドル５２の開弁操作によりスピンドル部５３が回動して引き上げ部材１３０ｂを引き上げると、フラッパー弁１２１は軸体１２１ａを中心にして上方に回動して排水口４０ａを開放して、図示しない水洗便器に洗浄水を供給している。
開弁動作の初期段階ではフラッパー弁１２１には上方からタンク本体内の洗浄水の初期水位の水頭圧が印加されており、引き上げ部材としての玉鎖１３０とフラッパー弁１２１との連結位置と軸体１２１ａとの距離が短かいので、フラッパー弁１２１を引き上げる際、開弁操作装置としてのスピンドル部５３に対して大きな回動トルクが必要とされている。前記回動トルクは、開弁操作を手動で行う場合は問題となる大きさではないが、開弁操作を電動モーターを用いて自動で行う場合は電動モーターに求められる出力トルクに影響してくる。
即ち、複数の洗浄水タンク装置を同一仕様の電動モーターを用いて自動洗浄を行う場合、前記同一仕様の電動モーターであっても電動モーターの各々の間で出力トルクが正規分布状にばらついている。正規分布状にばらついている中から必要とする出力トルクを発生する電動モーターを改めて検査して選定する手間が発生したり、必要とする出力トルクの下限値以下の電動モーターが多い場合最適モーターの収率が小さくなりコスト高になる。 In Patent Document 1, as shown in FIG. 7, the lifting member 130 b is connected to a substantially central position of the flapper valve 121, and the spindle portion 53 is rotated by the valve opening operation of the operation handle 52 as a valve opening operation device. When the lifting member 130b is pulled up, the flapper valve 121 rotates upward about the shaft body 121a to open the drain port 40a, and supplies cleaning water to a flush toilet (not shown).
In the initial stage of the valve opening operation, the head pressure of the initial water level of the cleaning water in the tank body is applied to the flapper valve 121 from above, and the connection position between the ball chain 130 as the lifting member and the flapper valve 121 and the shaft body. Since the distance to 121a is short, when the flapper valve 121 is pulled up, a large rotational torque is required for the spindle portion 53 as the valve opening operation device. The rotational torque is not a problem when the valve opening operation is manually performed, but when the valve opening operation is automatically performed using an electric motor, it affects the output torque required for the electric motor. .
That is, when performing automatic cleaning of a plurality of cleaning water tank devices using electric motors of the same specification, the output torque varies between the electric motors in a normal distribution even with the electric motors of the same specification. . If the electric motor that generates the required output torque out of the normal distribution varies, it will take time to check and select the electric motor again, or if there are many electric motors below the lower limit of the required output torque, The yield is reduced and the cost is increased.

特開平１０−２１９７８５（図１）JP-A-10-219785 (FIG. 1)

そこで、本発明は、洗浄水を貯留するタンク本体と、タンク本体の底部に配設した排水口を開閉するフラッパー弁と、前記フラッパー弁を開弁操作するための開弁操作装置と、この開弁操作装置と前記フラッパー弁を連繋する引き上げ部材とを備えた洗浄水タンク装置において、開弁操作を電動モーターを用いて自動で行う場合に、電動モーターの選定に制約が少ない洗浄水タンク装置を提供することを目的とする。   Accordingly, the present invention provides a tank body for storing cleaning water, a flapper valve for opening and closing a drain outlet disposed at the bottom of the tank body, a valve opening operation device for opening the flapper valve, In a washing water tank apparatus provided with a valve operating device and a lifting member for connecting the flapper valve, when the valve opening operation is automatically performed using an electric motor, the washing water tank apparatus with few restrictions on the selection of the electric motor is provided. The purpose is to provide.

上記課題を解決するために本発明は、洗浄水を貯留する洗浄水タンクと、この洗浄水タンクの底部に配設した排水口を開閉する弁体本体部とこの弁体本体部から延びた腕部とを有するフラッパー弁と、前記腕部を回動自在に支持する軸体と、前記フラッパー弁に一端部を係止して、このフラッパー弁を前記軸体を中心に上方に引き上げるための可撓性を有する引き上げ部材と、この引き上げ部材を引き上げ移動する、電動モーターによって駆動される開弁操作装置と、を備えた洗浄水タンク装置において、前記引き上げ部材は、前記弁体本体部の中心から前記軸体に対して遠ざかる側に係止した第１引き上げ部材と、前記弁体本体部の中心から前記軸体に近づく側に係止した第２引き上げ部材と、から構成され、前記第１引き上げ部材及び第２引き上げ部材の他端部が前記開弁操作装置に連繋されており、前記フラッパー弁の開弁開始においては、前記第１引き上げ部材は引張り状態で、前記第１引き上げ部材は弛緩状態で、その後全開弁までの間に、前記第１引き上げ部材が弛緩状態で、前記第２引き上げ部材が引張り状態となるように、前記第１引き上げ部材および第２引き上げ部材の長さを設定していることを特徴とする。   In order to solve the above-described problems, the present invention provides a cleaning water tank for storing cleaning water, a valve body main body for opening and closing a drain outlet disposed at the bottom of the cleaning water tank, and an arm extending from the valve body main body. A flapper valve having a portion, a shaft body that rotatably supports the arm portion, and one end portion locked to the flapper valve so that the flapper valve can be lifted upward with the shaft body as a center. In the washing water tank apparatus comprising a lifting member having flexibility and a valve opening operation device driven by an electric motor that lifts and moves the lifting member, the lifting member is disposed from the center of the valve body main body. The first lifting member locked to the side moving away from the shaft body and the second lifting member locked to the side approaching the shaft body from the center of the valve body main body, the first lifting member Member and number The other end portion of the lifting member is connected to the valve opening operation device. At the start of opening the flapper valve, the first lifting member is in a tensioned state, the first lifting member is in a relaxed state, and then fully opened. Before the valve, the lengths of the first lifting member and the second lifting member are set so that the first lifting member is in a relaxed state and the second lifting member is in a tensioned state. And

上記のように構成された本発明においては、開弁操作をするために電動モーターを作動させて引き上げ部材を上方へ引上げることにより、二本の引き上げ部材の内、軸体から近い側の第２引き上げ部材よりも緩みの少ない遠い側に設置されている第１引き上げ部材がフラッパー弁を持上げることにより、フラッパー弁は開弁される。開弁角度が大きくなると幾何学的に第２引き上げ部材の緩みがなくなり緊張状態に達してフラッパー弁を持上げる。この時第１引き上げ部材は緊張状態から弛緩状態に移行しフラッパー弁を持上げる効果はなくなる。その後開弁終了まで第２引き上げ部材がフラッパー弁を引上げる。すなわち一連の開弁動作の内、前半部分が第１引き上げ部材でフラッパー排水弁を引き上げ、後半部分が第２引き上げ部材でフラッパー排水弁を引上げる。   In the present invention configured as described above, the electric motor is operated to open the valve, and the lifting member is pulled upward, so that the second of the two lifting members on the side closer to the shaft body. The flapper valve is opened when the first pulling member installed on the far side with less looseness than the two lifting members lifts the flapper valve. When the valve opening angle is increased, the second lifting member is geometrically loosened and reaches a tension state to lift the flapper valve. At this time, the first lifting member shifts from the tensioned state to the relaxed state, and the effect of lifting the flapper valve is lost. Thereafter, the second lifting member raises the flapper valve until the valve opening is completed. That is, in the series of valve opening operations, the first half part pulls up the flapper drain valve with the first lifting member, and the second half part pulls up the flapper drain valve with the second lifting member.

また、本発明においては、前記引き上げ部材を玉鎖で構成し、前記第１引き上げ部材と前記第２引き上げ部材の何れかに一方に他方を着脱自在に係止する玉鎖係止部を配設して、この玉鎖係止部の係止位置を調節することで、前記第１引き上げ部材と前記第２引き上げ部材の相対長さを調整可能であることも特徴とする。
従って、フラッパー弁が閉弁状態から開弁状態に至るまでの、各引き上げ部材における、引き上げ分担割合を簡単に調節することができる。 Further, in the present invention, the lifting member is constituted by a ball chain, and a ball chain locking portion for detachably locking one of the first lifting member and the second lifting member on one side is disposed. And the relative length of the said 1st raising member and the said 2nd raising member can be adjusted by adjusting the latching position of this ball chain latching | locking part, It is also characterized by the above-mentioned.
Therefore, it is possible to easily adjust the lifting share ratio of each lifting member from the closed state to the opened state of the flapper valve.

本発明によれば、最初は引き上げ力に有利だが引き上げ距離に不利であるフラッパー弁の軸体から遠い側にある第１引き上げ部材でフラッパー弁を引き上げ、フラッパー弁が開弁し、引き上げ負荷の少なくなった時に引き上げ力が少なく引き上げ距離の大きなフラッパー弁の軸体から近い側の第２引き上げ部材でフラッパー弁を引上げることにより、従来より受圧面積の大きいフラッパー弁を用いても引き上げ部材を操作する電動モーターのトルクを増加させることなく従来の引き上げ距離でフラッパー弁を開弁させることができる。   According to the present invention, the flapper valve is lifted by the first pulling member on the side far from the shaft body of the flapper valve, which is advantageous for the pulling force but disadvantageous for the pulling distance, and the flapper valve is opened, so that the lifting load is small. By pulling up the flapper valve with the second lifting member on the side closer to the flapper valve shaft having a small pulling force and a large pulling distance, the pulling member can be operated even when a flapper valve having a larger pressure receiving area is used. The flapper valve can be opened at a conventional lifting distance without increasing the torque of the electric motor.

以下、図面に基づいて本発明に係る洗浄水タンク装置の実施形態を説明する。   Hereinafter, embodiments of a cleaning water tank apparatus according to the present invention will be described with reference to the drawings.

図１は本発明の第１の実施の形態にかかる洗浄水タンク装置を示す断面図である。図２は図１の便器用洗浄水タンク装置５０の排水弁が開閉する前状態を説明する説明図である。
図１において、洗浄水タンク装置５０は二本の引き上げ部材としての玉鎖で弁体を引上げることで電動モーターの負荷トルクを軽減させるものであり、洗浄水を貯える樹脂によって形成されたタンク本体１４０には、洗浄水の排水弁装置２０が設けられており、この排水弁装置２０は、下部に排水口２３を有するオーバーフロー管２２と、この排水口２３を開閉するフラッパー弁２１を有しており、このフラッパー弁２１をオーバーフロー管２２の周面に設けられた軸体２２ａに回動可能に取り付ている。フラッパー弁２１は、排水口２３の周面に当接して排水口２３を閉止する弁体本体部２１ｃと、この弁体本体部から軸体２２ａに向かって延びた一対の脚部２１ｄとから構成されている。弁体本体部２１ｃと脚部２１ｄとは軟質樹脂によって一体に形成されている。また、このタンク本体１４０の上部には開弁操作装置１０が設けられており、この開弁操作装置１０とフラッパー弁２１とを連結する第１玉鎖３０ａと第２玉鎖３０bとを備えている。 FIG. 1 is a cross-sectional view showing a washing water tank apparatus according to a first embodiment of the present invention. FIG. 2 is an explanatory view for explaining a state before the drain valve of the toilet flush water tank device 50 of FIG.
In FIG. 1, a washing water tank device 50 reduces the load torque of an electric motor by pulling up a valve body with a ball chain as two lifting members, and a tank main body formed of a resin for storing washing water 140 is provided with a drain valve device 20 for washing water. The drain valve device 20 includes an overflow pipe 22 having a drain port 23 at a lower portion and a flapper valve 21 for opening and closing the drain port 23. The flapper valve 21 is rotatably attached to a shaft body 22 a provided on the peripheral surface of the overflow pipe 22. The flapper valve 21 includes a valve body main body portion 21c that contacts the peripheral surface of the drain port 23 to close the drain port 23, and a pair of leg portions 21d extending from the valve body main body portion toward the shaft body 22a. Has been. The valve body main body 21c and the leg 21d are integrally formed of a soft resin. In addition, a valve opening operation device 10 is provided on the upper portion of the tank body 140, and includes a first ball chain 30a and a second ball chain 30b that connect the valve opening operation device 10 and the flapper valve 21. Yes.

タンク本体１４０の上部には、このタンク本体１４０内の水位に応じて給水動作を行なうボールタップ（図示せず）が設けられている。このボールタップは、周知の構成であり、すなわち、水道管に接続された給水弁と、タンク本体１４０の水位に応じて上下動して上記給水弁を開閉するフロートとを備え、タンク本体１４０内の洗浄水の水位が低下したときにフロートが下降することにより給水弁を開き、一方、タンク本体１４０内への給水により水位が上昇したときにフロートが上昇することにより給水弁を閉じ、これにより、タンク本体１４０内を所定の水位状態に維持するものである。   A ball tap (not shown) that performs a water supply operation according to the water level in the tank main body 140 is provided on the upper portion of the tank main body 140. This ball tap has a known configuration, that is, a water supply valve connected to a water pipe, and a float that moves up and down according to the water level of the tank main body 140 to open and close the water supply valve. When the water level of the washing water is lowered, the float is lowered to open the water supply valve, while when the water level is raised by the water supply into the tank body 140, the float is raised to close the water supply valve. The inside of the tank body 140 is maintained at a predetermined water level.

また、上記フラッパー弁２１は、水没状態であっても閉弁する方向へ付勢されるように構成される。つまり、弁体本体部２１ｃの内部に形成された空洞部２１ｅと、弁体本体部２１ｃの自体及び錘重２１ｆにより水より比重を大きくしている。なお、比重の調整に限らず、スプリングで閉弁方向に付勢力を加えて閉弁するように構成することもできる。   Further, the flapper valve 21 is configured to be biased in a closing direction even in a submerged state. That is, specific gravity is made larger than water by the cavity part 21e formed in the inside of the valve body main-body part 21c, the valve body main-body part 21c itself, and the weight 21f. In addition, not only adjustment of specific gravity but it can also comprise so that a urging | biasing force may be applied in the valve closing direction with a spring.

さらに上記フラッパー弁２１の弁体本体部２１ｃには、第１玉鎖３０ａを接続させるための突起２１ａと第２玉鎖３０ｂを接続させるための突起２１ｂを備えている。突起２１ａはフラッパー弁２１の弁体本体部２１ｃの中心線ＣＬから軸体２２ａに対して遠ざかる側に設置されている。突起２１ｂはフラッパー弁２１の中心線ＣＬより軸体２２ａに近い側に設置されている。なお、この中心線ＣＬは、弁体本体部２１ｃのシート面の中心、即ち、排水口２３と当接する円の中心を通る法線である。   Further, the valve body main part 21c of the flapper valve 21 is provided with a protrusion 21a for connecting the first ball chain 30a and a protrusion 21b for connecting the second ball chain 30b. The protrusion 21a is installed on the side away from the center line CL of the valve body main body 21c of the flapper valve 21 with respect to the shaft body 22a. The protrusion 21b is disposed closer to the shaft body 22a than the center line CL of the flapper valve 21. The center line CL is a normal line passing through the center of the seat surface of the valve body main body 21c, that is, the center of a circle in contact with the drain port 23.

タンク側壁部１４１の上部には上記開弁操作装置１０が設けられている。この開弁操作装置１０はケース本体１１と、このケース本体１１に回動自在に設置されたスピンドル１２と、スピンドル１２の先端に枢着されたレバー１４と、スピンドル１２とレバー１４に嵌挿してレバー１４をスピンドル１２に拘止するためのピン１３を備えている。
このケース本体１１には、ＤＣモーターと減速ギア列とが収納されており、図示しないリモコンからの信号に基づいてＤＣモータが回転し、その回転を減速ギア列によってトルクを高めてスピンドルに伝達する。そして、このスピンドル１２の回転軸としてレバー１４が回動する。 Above the tank side wall 141, the valve opening operation device 10 is provided. The valve opening operating device 10 is fitted into the case main body 11, a spindle 12 rotatably installed on the case main body 11, a lever 14 pivotally attached to the tip of the spindle 12, and the spindle 12 and the lever 14. A pin 13 for holding the lever 14 to the spindle 12 is provided.
The case body 11 houses a DC motor and a reduction gear train. The DC motor rotates based on a signal from a remote controller (not shown), and the rotation is transmitted to the spindle by increasing the torque by the reduction gear train. . Then, the lever 14 rotates as the rotation axis of the spindle 12.

上記レバー１４のスリット１４ａには第１玉鎖３０aと第２玉鎖３０bが装着されており、レバー１４が回動することにより、第１玉鎖３０aと第２玉鎖３０bとが引き上げられる。   A first ball chain 30a and a second ball chain 30b are mounted on the slit 14a of the lever 14, and when the lever 14 is rotated, the first ball chain 30a and the second ball chain 30b are pulled up.

次に洗浄水タンク装置５０の一連の排水動作について説明する。いま、図２に示すようにフラッパー弁２１が閉じている状態にあるとする。この状態で第２玉鎖３０ｂは第１玉鎖３０ａに比べて緩んでいる。具体的には、第１玉鎖３０ａと第２玉鎖３０ｂとは同じ長さであるが、フラッパー弁２１が突起２１ａが突起２１ｂに比べて低くなるように傾斜しており、また、レバー１４のスリット１４ａから図２の紙面左右方向における距離も突起２１ａが突起２１ｂに比べて長いことから、第１玉鎖３０ａに比べて第２玉鎖３０ｂが緩んだ状態である。なお、この図２のフラッパー弁２１が閉じている状態においては、第１玉鎖３０ａも僅かに緩んでいるように設計されている。   Next, a series of draining operations of the cleaning water tank apparatus 50 will be described. Assume that the flapper valve 21 is closed as shown in FIG. In this state, the second ball chain 30b is looser than the first ball chain 30a. Specifically, the first ball chain 30a and the second ball chain 30b have the same length, but the flapper valve 21 is inclined so that the projection 21a is lower than the projection 21b, and the lever 14 Since the protrusion 21a is longer than the protrusion 21b from the slit 14a in the left-right direction in FIG. 2, the second ball chain 30b is loosened compared to the first ball chain 30a. In addition, when the flapper valve 21 of FIG. 2 is closed, the first ball chain 30a is also designed to be slightly loosened.

この状態から洗浄するために開弁操作装置１０を作動させる。上述したように、ケース本体１１に内蔵されたＤＣモータが作動するとスピンドル１２が回転し、それに伴いレバー１４も同方向に回転する。レバー１４が回転することによりレバー１４先端が上方に持ち上がることに伴って玉鎖３０aと玉鎖３０bも同時に引上げられる。先に玉鎖３０aが緊張状態になり突起２１ａを持上げることで弁体部材２１が持上がり開弁する。この時突起２１ａは軸体２２ａから外側にある突起なので、幾何学的理由により、軸体２２ａから内側の突起である突起２１ｂを持ち上げてフラッパー弁２１を引上げる場合よりもレバー１４の引上げ荷重は少なくてすむ。   In order to wash from this state, the valve opening operating device 10 is operated. As described above, when the DC motor built in the case main body 11 operates, the spindle 12 rotates, and the lever 14 also rotates in the same direction. As the lever 14 rotates, the tip of the lever 14 is lifted upward, and the ball chain 30a and the ball chain 30b are simultaneously pulled up. First, the ball chain 30a is in a tension state and lifts the protrusion 21a, whereby the valve body member 21 is lifted and opened. At this time, since the protrusion 21a is an outer protrusion from the shaft body 22a, the pulling load of the lever 14 is larger than the case where the protrusion 21b which is the inner protrusion is lifted from the shaft body 22a and the flapper valve 21 is pulled up for geometric reasons. Less.

さらにレバー１４を回転させると第２玉鎖３０bが緊張状態に達し、突起２１ｂが持上がろうとする。この瞬間、突起２１ａと突起２１ｂは同時に上方に引上げられる（図３参照）。
さらにレバー１４を回転させると第２玉鎖３０ｂの緊張状態を持続し、第１玉鎖３０ａは緊張状態から緩和状態になる（図４参照）。その瞬間から突起２１ａの上方からの引き上げ力がなくなり、突起２１ｂにのみ引き上げ力がかかる。すなわち第２玉鎖３０ｂでのみでフラッパー弁２１を引上げている状態になる。一般に排水弁装置２０が大気中に存在する場合、幾何学的にみて軸体２２ａに近い突起２１ｂを引上げてフラッパー弁２１を持上げることは突起２１ａを引上げてフラッパー弁２１を持上げる時よりも引き上げ荷重がかかってしまう。
しかし、実際には、排水弁装置２０は水中に没しているため、フラッパー弁２１には上方から水圧が弁上面にかかっているので、大気中にある場合よりも開弁させるのに引き上げ荷重が必要になるが、一度開弁してしまえばフラッパー弁２１の上面と下面の圧力差が減少し、大気中よりも大きな浮力が作用するので、突起２１ｂを引上げる場合でも開弁させることが可能である。 When the lever 14 is further rotated, the second ball chain 30b reaches a tension state, and the protrusion 21b tends to lift. At this moment, the protrusion 21a and the protrusion 21b are simultaneously pulled upward (see FIG. 3).
When the lever 14 is further rotated, the tension state of the second ball chain 30b is maintained, and the first ball chain 30a is changed from the tension state to the relaxed state (see FIG. 4). From that moment, the lifting force from above the protrusion 21a is lost, and the lifting force is applied only to the protrusion 21b. That is, the flapper valve 21 is pulled up only by the second ball chain 30b. In general, when the drain valve device 20 exists in the atmosphere, lifting the flapper valve 21 by raising the protrusion 21b close to the shaft body 22a in terms of geometry is higher than when lifting the flapper valve 21 by lifting the protrusion 21a. Pulling load will be applied.
However, since the drain valve device 20 is actually submerged in water, the flapper valve 21 is subjected to water pressure on the upper surface of the valve from above, so that the lifting load is higher than that in the atmosphere. However, once the valve is opened, the pressure difference between the upper surface and the lower surface of the flapper valve 21 is reduced, and a greater buoyancy than in the atmosphere acts. Therefore, even when the protrusion 21b is pulled up, the valve can be opened. Is possible.

図５は本発明の第二の実施の形態にかかる便器用洗浄水タンク装置６０を示す断面図である。図５において便器用洗浄水タンク装置６０は図１の開弁操作装置１０と排水弁装置２０を備えている点が共通であり、二股玉鎖である玉鎖３０を用いた点が異なっている。このように、玉鎖３０は途中で第１玉鎖３０ａと第２玉鎖３０ｂとに分岐されており、そのため、レバー１４に対する取付け箇所が一箇所ですむため、取付け作業が簡単である。   FIG. 5 is a cross-sectional view showing a toilet flush water tank device 60 according to a second embodiment of the present invention. In FIG. 5, the toilet flush water tank device 60 is common in that the valve opening operation device 10 and the drain valve device 20 of FIG. 1 are provided, and the difference is that a ball chain 30 which is a bifurcated ball chain is used. . In this way, the ball chain 30 is branched into the first ball chain 30a and the second ball chain 30b on the way, and therefore, only one mounting position with respect to the lever 14 is required, so that the mounting operation is simple.
