本発明は、例えば水槽内に水を送る給水装置や、浴槽内
に湯を送る湯張り装置等の給水装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a water supply device, such as a water supply device for feeding water into an aquarium or a hot water filling device to feed hot water into a bathtub.
［先行の技術］
例えば、特願平２−８９５６１号公報（平成２年４月４
日出願）においては、第２図に示すように、水源から流

湯用加熱器１０１に燃料ガスを供給するガス通路１０５
等を備えた自動湯張り装置１００が提案されている。[Prior art] For example, Japanese Patent Application No. 2-89561 (April 4, 1990)
As shown in FIG. 2, a hot water supply passage 103 heats water flowing from a water source with a hot water heater 101 and sends the hot water into a bathtub 102, and the hot water in the bathtub 102 is directed to the tap water side. A backflow preventer i 104 that prevents backflow, and a gas passage 105 that supplies fuel gas to the hot water heater 101
An automatic hot water filling device 100 has been proposed.
例えば２階に浴槽１０２を設置した場合のように浴槽１
０２が自動湯張り装置１００に対して高所に設置され水
位が高い場合には、浴槽１０２への湯張りが完了すると
、浴槽１０２の水位に起因する高水圧が追焚き用加熱器
１０７を介して逆止弁１０８、圧力室１０９等に加わっ
た状態で湯張り弁１０６が閉弁する。このため、浴槽１
０２への湯張りが完了した後、大気開放弁１１０の上流
側の圧力室１０９内が高水圧に維持される。For example, if the bathtub 102 is installed on the second floor, the bathtub 1
02 is installed at a higher location than the automatic hot water filling device 100 and the water level is high, when the bathtub 102 is filled with hot water, the high water pressure caused by the water level in the bathtub 102 is applied via the reheating heater 107. The hot water filling valve 106 closes with the hot water applied to the check valve 108, the pressure chamber 109, etc. For this reason, bathtub 1
After the filling of water into the tank 02 is completed, the inside of the pressure chamber 109 on the upstream side of the atmosphere release valve 110 is maintained at a high water pressure.
その結果、高水圧により大気開放弁１１０は、浴槽１０
２への湯張り中における閉弁状態のまま維持され、圧力
室１０９内は水が溜まった状態となる。As a result, high water pressure causes the atmosphere release valve 110 to open in the bathtub 10.
The valve is maintained in the closed state during the filling of water into the pressure chamber 109, and the inside of the pressure chamber 109 becomes filled with water.
通常、この状態において、電動ポンプ１１１を作動させ
て圧力室１０９内の水を給湯通路１０３を介して浴槽１
０２へ送り込むが、このとき圧力室１０９内の圧力が低
下するため、大気開放弁１１０がスプリング１１２の弾
性力により開弁する。Normally, in this state, the electric pump 111 is operated to supply water in the pressure chamber 109 to the bathtub via the hot water supply passage 103.
At this time, the pressure inside the pressure chamber 109 decreases, so the atmosphere release valve 110 is opened by the elastic force of the spring 112.
その結果、大気供給路１１３、連通室１１４、大気開放
穴１１５を介して圧力室１０９内に大気が入り込むこと
によって、浴槽１０２側と上水側との縁切りがなされる
。As a result, the atmosphere enters the pressure chamber 109 through the atmosphere supply path 113, the communication chamber 114, and the atmosphere release hole 115, thereby separating the bathtub 102 side from the water supply side.

９との間に設けられており、閉弁状態の逆止弁１０８を
開弁させて、圧力室１０９内の圧力を低下させるために
は、別途設けた吸引手段（電動ポンプ等）を作動させる
必要があり、制御、ｉ造が複雑となる不具合かあった。[Problems to be Solved by the Invention] In the prior art, the check valve 108 connects the pressure chamber 10 to the confluence 117 where the discharge passage 116 and the hot water supply passage 103 merge.
In order to open the closed check valve 108 and lower the pressure in the pressure chamber 109, a separately provided suction means (such as an electric pump) is activated. However, there was a problem with the control and construction being complicated.
また、湯張りが完了した直後に停電した場合や断線した
場合等には、電動ポンプ１１１により圧力室１０９内の
水を浴槽１０２−に圧送することができない。このため
、圧力室１０９内かいつまでも高水圧に維持されてしま
うので、大気開放弁１１０は開弁されず、圧力室１０９
内に水が溜まったままとなってしまう。この結果、圧力
室１０９と水源側との縁切りが不充分となるという課題
があった。In addition, if there is a power outage or a disconnection immediately after filling with hot water, the electric pump 111 cannot forcefully transfer the water in the pressure chamber 109 to the bathtub 102-. For this reason, the pressure chamber 109 is maintained at a high water pressure forever, so the atmosphere release valve 110 is not opened and the pressure chamber 109 is kept at a high water pressure.
Water remains trapped inside. As a result, there was a problem that the separation between the pressure chamber 109 and the water source side was insufficient.
本発明は、水槽側と水源側および外部との縁切りを簡易
な方法で確実に行うことができる給水装置の提供を目的
とする。An object of the present invention is to provide a water supply device that can reliably separate the aquarium side, the water source side, and the outside using a simple method.

そして、浴槽４内の水位が所定の水位に達すると、湯張
り弁１２が閉じて浴槽４への湯張りが完了する。Then, when the water level in the bathtub 4 reaches a predetermined water level, the hot water filling valve 12 is closed and the filling of the bathtub 4 with hot water is completed.
なお、浴槽４が自動湯張り装置１に対して水位が高い場

溜まった状態となる。このとき、第２逆止弁２３は、浴
槽４の水位に起因する高水圧により閉弁状態となってい
る。Note that when the water level of the bathtub 4 is higher than that of the automatic hot water filling device 1, high water pressure due to the water level of the bathtub 4 is applied to the pressure chamber 18, so that the inside of the pressure chamber 18 is maintained at a high water pressure. As a result, the hot water filling valve 12 closes when hot water filling is completed under high water pressure, and the atmosphere release valve 21 remains closed while the bathtub 4 is being filled with hot water. becomes filled with water. At this time, the second check valve 23 is in a closed state due to high water pressure caused by the water level of the bathtub 4.

に開放される。Then, in order to recover the water remaining in the pressure chamber 18, the normally open electromagnetic valve 22 is opened. At this time, the second check valve 23
is provided on the bathtub 4 side from the confluence point 29, so that backflow from the bathtub 4 side is prevented, and the inside of the pressure chamber 18 is opened to the atmosphere via the atmosphere supply path 26, the communication chamber 25, and the discharge path 27. be done.
この結果、圧力室１８内の圧力が浴槽４の水位に起因す

プリング２８の弾性力により開弁し、大気開放穴２４を
開いて圧力室１８内に大気が入り込む。As a result, the pressure inside the pressure chamber 18 decreases from the high water pressure state caused by the water level in the bathtub 4, so the atmosphere release valve 21 is opened by the elastic force of the spring 28, and the atmosphere release hole 24 is opened to open the pressure chamber. Air enters into 18.
よって、上水道側と浴槽４側との間に大気が介在するこ
とになって上水道側と浴槽４側との縁切りがなされる。Therefore, the atmosphere is interposed between the water supply side and the bathtub 4 side, and a separation is made between the water supply side and the bathtub 4 side.
なお、大気と置換され、大気開放穴２４を介して連通室
２５内に溜まった水は、電動ポンプ１６の吸引力によっ
て強制的に浴槽４内に送り込まれる。Note that the water that has been replaced by the atmosphere and has accumulated in the communication chamber 25 through the atmosphere opening hole 24 is forced into the bathtub 4 by the suction force of the electric pump 16.
ところで、浴槽４への湯張りが完了した直後に停電ある

になって浴槽４側と上水道側との縁切りが確実になされ
る。By the way, even if there is a power outage or disconnection immediately after filling the bathtub 4 with hot water, the normally open solenoid valve 22 will not be energized.
Since it is a solenoid valve that opens when the power is turned off, it opens at the same time as the energization stops, opening the discharge passage 27. Therefore, similarly to the above, the atmosphere is interposed between the water supply side and the bathtub 4 side, and the separation between the bathtub 4 side and the water supply side is reliably achieved.
以上のように、本実施例は、浴槽４側と上水道側との縁
切りを簡易な方法で、しかも浴槽４への湯張りが完了し
た直後に停電あるいは断線したときでも確実に行うこと
ができる。As described above, in this embodiment, the separation between the bathtub 4 side and the water supply side can be performed in a simple manner and reliably even when there is a power outage or disconnection immediately after filling the bathtub 4 with hot water.

発明を水を加熱する加熱手段を持たない給水装置に用い
ても良い。(Modification) In this embodiment, the present invention was used in an automatic hot water filling device, but the present invention may also be used in a water supply device that does not have a heating means for heating water.
本実施例では、開閉弁として常開型電磁弁を用いたが、
停電や断線を考えなければ開閉弁として手動式の開閉弁
あるいは常閉型電磁弁を用いても良い。In this example, a normally open solenoid valve was used as the on-off valve, but
If power outage or disconnection is not a consideration, a manual on-off valve or a normally closed solenoid valve may be used as the on-off valve.
本実施例では、給湯通路やガス通路に各種電磁弁等を設
けたが、本発明を逸脱しない範囲内で増加したり、削減
したりすることができる。In this embodiment, various electromagnetic valves and the like are provided in the hot water supply passage and the gas passage, but the number may be increased or decreased without departing from the scope of the present invention.
