JP 2002-201680 A

ところでこの従来のものでは、既存の蛇口に取り付けて使用されるので、給水中に誤って蛇口の栓を閉めて給水を停止してしまうと、水車の回転が止まり蓄電が停止すると共に、電気駆動弁は開弁状態を維持するので電気を消費し、再使用では初期使用と同様に手動操作弁の操作による蓄電をしないといけない言う不具合が発生し、手間がかかるものであり、特にお年寄りの居る家庭に多く発生して、その度にサービスマンが出向くこととなり、更に手動操作弁がドライバー等の工具を必要とするものでは、簡単に上記のような初期設定をすることも出来ないものであった。   By the way, in this conventional one, it is used attached to an existing faucet, so if you accidentally close the faucet plug and stop water supply during water supply, the water turbine stops rotating and the electricity storage stops, and electric drive Since the valve keeps open, it consumes electricity, and in the case of re-use, there is a problem that it has to be stored by operating the manually operated valve as in the case of initial use. If it occurs frequently in the home where the service person goes, and the manual operation valve requires a tool such as a screwdriver, the initial setting as described above cannot be easily performed. there were.

そこで、この発明は上記課題を解決するため、特にその構成を、電気的に駆動され主水路を開閉する電気駆動弁と、該電気駆動弁とは並列の補助水路を開閉する手動操作弁と、前記補助水路の主水路への合流部の先で水流で回転する水車を備え、この水車の回転に基づいて発電する発電機と、該発電機で発電した電気を蓄電する蓄電器と、更に前記水車の回転数に応じたパルスを発生させ、該パルスのカウントにより主水路の積算流量を検知して設定値に達することで、電気駆動弁を閉弁させて給水停止させる制御部とで構成されたものに於いて、前記制御部には電気駆動弁が開弁状態で水流が停止した時には、前記電気駆動弁への通電を停止して強制的に閉弁させる安全装置を備え、更にこの安全装置は、電気駆動弁が開弁状態で水流が停止すると、カウントを開始し所定時間経過で、電気駆動弁への通電を停止して強制的に閉弁させるタイマー手段で構成されたものである。 Therefore, in order to solve the above-mentioned problems, the present invention has an electric drive valve that is electrically driven to open and close the main water passage, and a manually operated valve that opens and closes an auxiliary water passage parallel to the electric drive valve. A water turbine that rotates in a water flow at the end of the junction of the auxiliary water channel with the main water channel, a power generator that generates electric power based on the rotation of the water wheel, a capacitor that stores electricity generated by the power generator, and the water wheel The control unit is configured to generate a pulse corresponding to the number of rotations, detect the integrated flow rate of the main water channel by the count of the pulse, and reach a set value, thereby closing the electric drive valve and stopping water supply. in those, wherein when the electric drive valve to the control unit the water flow is stopped in an open state is provided with a safety device for forcibly closed by stopping the power supply to the electric drive valve, further the safety device The water flow is stopped when the electrically driven valve is open. Then, it starts counting a predetermined time has elapsed, in which the energization of the electric driven valve configured in the timer means for forcibly closing stop.

この発明によれば、蛇口の栓で給水が停止されたとしても、電気駆動弁は強制的に閉弁されて貯えた電気の消費は防止されるので、改めて蓄電の為の初期設定の必要がなく、面倒な作業をすることなく手間をかからないものであり、簡単な改良のみでこの種の止水装置の大きな問題点を解決出来、常に安心して使用される装置を提供出来るものである。   According to the present invention, even if the water supply is stopped by the tap of the faucet, the electric drive valve is forcibly closed and consumption of the stored electricity is prevented, so it is necessary to make an initial setting for power storage again. It is possible to provide a device that can always be used with peace of mind by solving a major problem of this type of water stop device with only a simple improvement.

次にこの発明の一実施形態を図面に基づいて説明する。
１は定量止水装置で、既存の蛇口の栓２から先を構成するものであり、給水を行う主水路３の先端には給水口４を備えている。
５は主水路３を開閉する電磁弁から成る電気駆動弁で、弁駆動部６からの信号で開閉させられる。 Next, an embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a fixed water stop device, which is formed at the tip of an existing faucet plug 2, and has a water supply port 4 at the tip of a main water channel 3 for supplying water.
5 is an electric drive valve comprising an electromagnetic valve for opening and closing the main water channel 3, and is opened and closed by a signal from the valve drive unit 6.

７は主水路３中に備えられた発電機で、水流により回転する水車８を有し、この水車８の回転で発電し、マイコンから成る制御部９に備えたコンデンサーから成る蓄電器１０に蓄電する。
１１は前記水車８の回転数に応じて発生するパルスをカウントするパルスカウンタで、このカウントするパルス数が設定値に達することで、制御部９を介して弁駆動部６から電気駆動弁５に閉弁信号を出力させ、該電気駆動弁５を閉弁させることで給水を停止させる。 Reference numeral 7 denotes a power generator provided in the main water channel 3, which has a water wheel 8 that is rotated by a water flow. .
Reference numeral 11 denotes a pulse counter that counts pulses generated according to the number of rotations of the water wheel 8. When the counted number of pulses reaches a set value, the valve drive unit 6 passes through the control unit 9 to the electric drive valve 5. Water supply is stopped by outputting a valve closing signal and closing the electric drive valve 5.

前記水車８の回転によって発生するパルスは、主水路３の通水の積算流量に対応したものとなり、パルス数が設定値に達したところで主水路３の通水を停止することにより、給水口４から確実に設定した流量で給水を行うことが出来るものである。   The pulse generated by the rotation of the water turbine 8 corresponds to the integrated flow rate of the main water passage 3, and when the number of pulses reaches the set value, the water supply port 4 is stopped by stopping the water passage of the main water passage 3. Therefore, water can be supplied at a surely set flow rate.

１２は電気駆動弁５を迂回する並列の補助水路１３に備えられた手動操作弁で、定量止水装置１の取り付け当初の初期設定時に、ドライバー使用の手動でこの手動操作弁１２を開弁して電気駆動弁５を迂回する水流を造り、水車８を数分間回転させることで始動用の電気を蓄電器１０に蓄電するものである。   Reference numeral 12 denotes a manually operated valve provided in the parallel auxiliary water channel 13 that bypasses the electric drive valve 5. The manual operated valve 12 is manually opened by a driver at the initial setting of the fixed water stop device 1. Thus, a water flow that bypasses the electric drive valve 5 is created, and the water for starting is stored in the battery 10 by rotating the water wheel 8 for several minutes.

１４は制御部９に備えられた安全装置を構成するタイマー手段で、電気駆動弁５が開弁状態で水流が停止すると、カウントを開始し所定時間ここでは１０秒経過で、該電気駆動弁５への通電を停止して強制的に閉弁させ、蓄電器１０の電力消費を防止する。   Reference numeral 14 denotes a timer means that constitutes a safety device provided in the control unit 9. When the electric drive valve 5 is open and the water flow is stopped, counting starts and the electric drive valve 5 starts counting for a predetermined time, 10 seconds here. The energization of the battery 10 is stopped and the valve is forcibly closed to prevent the power consumption of the battery 10.

１５は押圧毎にＯＮとＯＦＦを交互に繰り返す運転スイッチで、ＯＮすることで弁駆動部６から開弁信号を出力させて電気駆動弁５を開弁し、更に押圧することでＯＦＦとなり弁駆動部６から閉弁信号を出力させて電気駆動弁５を閉弁させる。   15 is an operation switch that alternately repeats ON and OFF each time it is pressed. When it is turned ON, a valve opening signal is output from the valve drive unit 6 to open the electric drive valve 5, and when it is further pressed, the valve is turned OFF. The valve drive signal is output from the unit 6 to close the electric drive valve 5.

１６は温度等を表示する表示部で、主水路３途中に備えられた温度センサ１７が検知した流水温度を制御部９を介して表示するものである。   Reference numeral 16 denotes a display unit for displaying temperature and the like, which displays the running water temperature detected by the temperature sensor 17 provided in the middle of the main water channel 3 through the control unit 9.

次にこの実施形態の作動について説明すれば、先ず取り付け後の初期設定では、蛇口の栓２を開けた状態とし、手動操作弁１２をドライバー使用の手動で開弁することにより、補助水路１３に電気駆動弁５を迂回する水流が形成されて、水車８が数分間回転させることで始動用の電気を蓄電器１０に蓄電するものであり、その後再びドライバーを使用して手動操作弁１２は閉弁されて初期設定は終了する。   Next, the operation of this embodiment will be described. First, in the initial setting after installation, the faucet plug 2 is opened, and the manual operation valve 12 is manually opened using a driver, so that the auxiliary water channel 13 is opened. A water flow that bypasses the electric drive valve 5 is formed, and the water wheel 8 rotates for several minutes to store the electricity for start-up in the battery 10, and then the manual operation valve 12 is closed again using a driver. This completes the initial setting.

そして使用者自身が風呂桶一杯とかの希望する積算流量を制御部９に記憶させ設定値を決定してから、運転スイッチ１５をＯＮすると、電気駆動弁５が弁駆動部６かんの信号で開弁されて、主水路３に水流が発生し水車８を回転させることで、蓄電器１０に蓄電すると共に、この水車８の回転数に応じて発生するパルスをパルスカウンタ１１がカウントし、パルス数が設定値に達することにより電気駆動弁５を自動的に閉弁させることで、使用者が希望する設定量の流量を得ることが出来るものである。   Then, when the user himself / herself memorizes the accumulated flow rate desired to fill the bath in the control unit 9 and determines the set value, when the operation switch 15 is turned on, the electric drive valve 5 is opened by a signal from the valve drive unit 6. When the water flow is generated in the main water channel 3 and the water wheel 8 is rotated, the electric power is stored in the capacitor 10, and the pulse counter 11 counts the pulses generated according to the rotation speed of the water wheel 8. By automatically closing the electric drive valve 5 by reaching the set value, a flow rate of a set amount desired by the user can be obtained.

次に前記の給水中に運転スイッチ１５をＯＦＦすることなく、断水や蛇口の栓２を閉めて給水を止める異常時について、図２のフローチャートで説明すれば、ステップ１８で水流が停止することで水車８によるパルス数のカウントが停止したかを判断し、ＹＥＳでステップ１９に進み電気駆動弁５が開弁状態かを判断し、ＮＯではステップ２０で水車８かパルスカウンタ１１或いは電気駆動弁５が異常状態であるとして、表示部１６にエラー表示する。   Next, in the case of an abnormal condition in which the water supply is stopped by turning off the faucet 2 by closing the faucet 2 without turning off the operation switch 15 during the water supply, the flow of water is stopped in step 18. It is determined whether the counting of the number of pulses by the water turbine 8 has stopped. If YES, the process proceeds to step 19 to determine whether the electrically driven valve 5 is open. If NO, the turbine 8 or the pulse counter 11 or the electrically driven valve 5 is determined in step 20. Is displayed in an error state on the display unit 16.

前記ステップ１９で電気駆動弁５が開弁状態でＹＥＳの場合には、ステップ２１に進みタイマー手段１４がカウントを開始し、そしてステップ２２に進んで１０秒経過することで、異常と判断してステップ２３で制御部９からの信号で、弁駆動部６を介して電気駆動弁５への通電を停止して強制的に閉弁させるものである。   If the electric drive valve 5 is in the open state in step 19 and the answer is YES, the process proceeds to step 21 and the timer means 14 starts counting, and then proceeds to step 22 and 10 seconds elapse, and it is determined that there is an abnormality. In step 23, a signal from the control unit 9 is used to stop energization of the electric drive valve 5 via the valve drive unit 6 and forcibly close the valve.

従って、断水や蛇口の栓２で給水が停止されたとしても、電気駆動弁５は蓄電器１０の電力がなくなるまで開弁状態を維持することがなく、蓄電器１０の電力は保持されるので、改めて蓄電の為の初期設定の必要がなく、面倒な作業をすることなく手間をかからないものであり、簡単な改良のみでこの種の止水装置の大きな問題点を解決出来、常に安心して使用される装置を提供出来るものである。   Therefore, even if the water supply is stopped by the water stop or the faucet plug 2, the electric drive valve 5 does not maintain the valve open state until the electric power of the electric condenser 10 is exhausted, and the electric power of the electric condenser 10 is maintained. There is no need for initial settings for power storage, and there is no need for troublesome work, so it is possible to solve major problems with this type of water stop device with only simple improvements, and it is always used with peace of mind. A device can be provided.
