Description

本発明は浴槽内の液位を制御する浴槽の液位制御装置に係り、特に、構成を簡略化させるとともに浴槽としての使い勝手を向上させることができるように工夫したものに関する。   The present invention relates to a liquid level control device for a bathtub that controls the liquid level in the bathtub, and more particularly, to a device that is devised so as to simplify the configuration and improve the usability as a bathtub.

浴槽には給水管が接続されていて、該給水管には電磁開閉弁が介挿されている。又、浴槽内には液位検出用の棒状の電極が複数本設置されている。例えば、所定の長さに調整された液位高検出用電極棒、液位低検出用電極棒、コモン用電極棒が浴槽内に設置されている。それら液位高検出用電極棒、液位低検出用電極棒、コモン用電極棒からの信号は制御装置に入力されるようになっている。制御装置はそれら液位高検出用電極棒、液位低検出用電極棒、コモン用電極棒からの信号に基づいて「液位高」、「液位低」を検出し、それによって、電磁開閉弁の開閉を制御するものである。すなわち、「液位低」を検出した場合には電磁開閉弁を開放して給水を行う。一方、「液位高」を検出した場合には、電磁開閉弁を閉じて給水を停止するものである。   A water supply pipe is connected to the bathtub, and an electromagnetic on-off valve is inserted in the water supply pipe. A plurality of bar-shaped electrodes for detecting the liquid level are installed in the bathtub. For example, a liquid level high detection electrode bar, a liquid level low detection electrode bar, and a common electrode bar adjusted to a predetermined length are installed in the bathtub. Signals from the liquid level high detection electrode bar, the liquid level low detection electrode bar, and the common electrode bar are input to the control device. The control device detects "liquid level high" and "liquid level low" based on the signals from these liquid level high detection electrode bar, liquid level low detection electrode bar, and common electrode bar, thereby opening and closing the electromagnetic It controls the opening and closing of the valve. That is, when “low liquid level” is detected, the electromagnetic on-off valve is opened to supply water. On the other hand, when “high liquid level” is detected, the electromagnetic on-off valve is closed to stop water supply.

その他様々な電極構造によって浴槽内の液位を検出する装置が提案されている。
そのようなものの一例を開示するものとして、例えば、特許文献１がある。

上記一対の液位高検出電極用ねじ部材１１、１３と、一対の液位低検出電極用ねじ部材１５、１７からの信号は制御手段２１に入力されるようになっている。又、上記浴槽７には防水用金具２６を介して給水管２３が接続されていてこの給水管２３には電磁開閉弁２５が介挿されている。   Signals from the pair of liquid level high detection electrode screw members 11, 13 and the pair of liquid level low detection electrode screw members 15, 17 are input to the control means 21. A water supply pipe 23 is connected to the bathtub 7 via a waterproof metal fitting 26, and an electromagnetic open / close valve 25 is inserted in the water supply pipe 23.

上記制御手段２１は複数個のリレーやタイマー等から構成されたシーケンス回路として構成されていて、図５に示すような端子台５１を備えている。既に説明した一対の液位高検出電極用ねじ部材１１、１３と、一対の液位低検出電極用ねじ部材１５、１７は、夫々リート線５３、５５、５７を介して上記端子台５１に接続されている。
但し、上記液位高検出電極用ねじ部材１３と液位低検出電極用ねじ部材１７については一本のリード線５７に纏められた状態で上記端子台５１に接続されるものである。
その他、ＡＣ１００Ｖ電源５９があり、このＡＣ１００Ｖ電源５９はリード線６１、６３、６５を介して上記端子台５１に接続されている。又、上記電磁開閉弁２５はリード線６５、６７、６９を介して端子台５１に接続されている。又、お湯張りスイッチ７１があり、このお湯張りスイッチ７１はリード線７３、７５、７７を介して端子台５１に接続されている。 The control means 21 is configured as a sequence circuit including a plurality of relays, timers, and the like, and includes a terminal block 51 as shown in FIG.

However, the liquid level high detection electrode screw member 13 and the liquid level low detection electrode screw member 17 are connected to the terminal block 51 in a state of being bundled in one lead wire 57.
In addition, there is an AC 100V power source 59, and this AC 100V power source 59 is connected to the terminal block 51 via lead wires 61, 63, 65. The electromagnetic on-off valve 25 is connected to the terminal block 51 through lead wires 65, 67 and 69. There is also a hot water filling switch 71, which is connected to the terminal block 51 via lead wires 73, 75, 77.

以上の構成を基にその作用を説明する。まず、空の浴槽７内に湯を張る場合には湯張りスイッチ７１を押圧・操作する。それによって、電磁開閉弁２５が開弁されて浴槽７内へのお湯張りが開始される。
尚、お湯張りスイッチ７１が二回続けて押圧・操作された場合には電磁開閉弁２５は閉弁されることになり、お湯張りは停止される。 The operation will be described based on the above configuration. First, when filling hot water in the empty bathtub 7, the hot water filling switch 71 is pressed and operated. Thereby, the electromagnetic opening / closing valve 25 is opened and hot water filling into the bathtub 7 is started.
When the hot water filling switch 71 is pressed and operated twice in succession, the electromagnetic on-off valve 25 is closed and the hot water filling is stopped.

お湯張り開始後二分経過した時点で下限ストップ水位センサ、すなわち、液位低検出電極用ねじ部材１５にまで浴槽７内の水位が達していない場合には電磁開閉弁２５が閉弁されて浴槽７内へのお湯張りが停止される。又、お湯張り開始後１０分経過した場合にも電磁開閉弁２５が閉弁されて浴槽７内へのお湯張りが停止される。又、浴槽７内の水位が上限ストップ水位センサ、すなわち、液位高検出電極用ねじ部材１１に達した場合にも、電磁開閉弁２５が閉弁されて浴槽７内へのお湯張りが停止される。 When the water level in the bathtub 7 has not reached the lower limit stop water level sensor, that is, the liquid level low detection electrode screw member 15 when two minutes have passed after the start of hot water filling, the electromagnetic on-off valve 25 is closed and the bathtub 7 Hot water filling inside is stopped. Also, when 10 minutes have passed since the start of hot water filling, the electromagnetic on-off valve 25 is closed and hot water filling into the bathtub 7 is stopped. Further, when the water level in the bathtub 7 reaches the upper limit stop water level sensor, that is, the screw member 11 for the liquid level high detection electrode, the electromagnetic on-off valve 25 is closed and the filling of the hot water into the bathtub 7 is stopped. The

尚、本実施の形態の場合には上記制御を複数個のリレーとタイマー等からなるシーケンス回路によって実現する構成になっているが、これをソフト的に実行することも可能である。それを図６を参照して説明する。 In the present embodiment, the above control is realized by a sequence circuit composed of a plurality of relays and timers, but this can also be executed in software. This will be described with reference to FIG.

図６は情報処理の内容を示すフローチャートである。まず、ステップＳ１において、お湯張りスイッチ７１が押されたか否かが判別される。お湯張りスイッチ７１が押圧・操作されたと判別された場合にはステップＳ２に移行してお湯張りが開始される。これに対して、お湯張りスイッチ７１が押圧・操作されていないと判別された場合には同判別が繰り返し実行される。 FIG. 6 is a flowchart showing the contents of information processing. First, in step S1, it is determined whether or not the hot water filling switch 71 has been pressed. If it is determined that the hot water filling switch 71 has been pressed and operated, the process proceeds to step S2 and hot water filling is started. On the other hand, when it is determined that the hot water filling switch 71 is not pressed and operated, the same determination is repeatedly performed.

次に、ステップＳ３に移行して、お湯張りスイッチ７１が二回押されたか否かが判別される。お湯張りスイッチ７１が二回押されていると判別された場合には、ステップＳ７に移行して給水が停止される。お湯張りスイッチ７１が二回押されていないと判別された場合には、ステップＳ４に移行する。このステップＳ４においては、お湯張り開始後二分以内に下限水位センサ１５に水位が達したか否かが判別される。お湯張り開始後二分以内に下限水位センサ１５に水位が達していないと判別された場合には、ステップＳ７に移行して給水が停止される。これに対して、お湯張り開始後二分以内に下限水位センサ１５に水位が達していると判別された場合にはステップＳ５に移行する。 Next, the process proceeds to step S3, where it is determined whether or not the hot water filling switch 71 has been pressed twice. When it is determined that the hot water filling switch 71 is pressed twice, the process proceeds to step S7, and water supply is stopped. If it is determined that the hot water filling switch 71 is not pressed twice, the process proceeds to step S4. In step S4, it is determined whether or not the water level has reached the lower limit water level sensor 15 within 2 minutes after the start of hot water filling. If it is determined that the water level has not reached the lower limit water level sensor 15 within two minutes after the start of hot water filling, the process proceeds to step S7 and water supply is stopped. On the other hand, if it is determined that the water level has reached the lower limit water level sensor 15 within 2 minutes after the start of hot water filling, the process proceeds to step S5.

ステップＳ５においては、お湯張り開始後１０分が経過しているか否かが判別される。お湯張り開始後１０分が経過していると判別された場合にはステップＳ７に移行して給水が停止される。お湯張り開始後１０分が経過していないと判別された場合にはステップＳ６に移行する。このステップＳ６においては、水位が上限水位センサ１１に達しているか否かが判別される。水位が上限水位センサ１１に達していると判別された場合にはステップＳ７に移行して給水が停止される。これに対して、水位が上限水位センサ１１に達していないと判別された場合には、ステップＳ３に戻って同様の処理が繰り返されることになる。   In step S5, it is determined whether 10 minutes have elapsed since the start of hot water filling. When it is determined that 10 minutes have passed since the start of hot water filling, the process proceeds to step S7 and water supply is stopped. If it is determined that 10 minutes have not passed since the start of hot water filling, the process proceeds to step S6. In step S6, it is determined whether or not the water level has reached the upper limit water level sensor 11. When it is determined that the water level has reached the upper limit water level sensor 11, the process proceeds to step S7 and water supply is stopped. On the other hand, when it is determined that the water level has not reached the upper limit water level sensor 11, the process returns to step S3 and the same process is repeated.
