Description

本発明は主として、家庭用給湯配管の、即湯装置及び給湯給水管凍結防止装置である。The present invention mainly relates to a hot water supply device and a hot water supply / water supply pipe freezing prevention device for domestic hot water supply piping.

従来給湯装置の一つとして、蛇口を開くと、即お湯が出る即湯方式、また凍結防止方式として、ポンプを使っての、循環方式があった。As one of the conventional hot water supply systems, there is an immediate hot water system that immediately produces hot water when the faucet is opened, and a circulation system that uses a pump as a freeze prevention system.

これには次のような欠点があった。
（イ）配管、往復のため保温資材が多く必要。
（ロ）配管放熱面積の拡大。
（ハ）施工時間施工技術が必要。
（ニ）ポンプが必要。
（ホ）ポンプの運転維持費が必要。
（ヘ）騒音が、発生する。
（ト）接続箇所が増える。
（チ）配管スペースが多く必要。
本発明は、以上のような欠点をなくすためになされたものである。This has the following drawbacks.
(A) Many heat insulation materials are required for piping and reciprocation.
(B) Expansion of piping heat dissipation area.
(C) Construction time Construction technology is required.
(D) A pump is required.
(E) Pump operation and maintenance costs are required.
(F) Noise is generated.
(G) The number of connection points increases.
(H) Requires a lot of piping space.
The present invention has been made to eliminate the above drawbacks.

即湯装置本体（１）に取り付けた、各給湯枝管（２）の中に給湯本管（３）を給湯蛇口（４）の直前まで通す、この給湯本管（３）は、給湯装置本体（１）を貫き、給湯溜まり（５）に接続する。The hot water supply main (3) is passed through the hot water supply branch pipes (2) attached to the hot water supply main body (1) until just before the hot water supply faucet (4). Go through (1) and connect to hot water reservoir (5).

給湯溜まり（５）は、給湯受け口（６）を経て給湯器につながり、一定圧、一定温度の、温水供給を受ける。The hot water reservoir (5) is connected to the hot water heater via the hot water supply port (6) and receives a supply of hot water at a constant pressure and a constant temperature.

給湯装置本体の動作１、数ある蛇口の中の、開かれた蛇口（４“）には、給湯本管（３）より、温水が流れるが、給湯本管（３）は、細く、給湯不足となり，必然的に他の枝管（２）の中の湯、冷めていれば水が流れ込む、必要数設置された他の枝管（２）の、すべてには給湯本管（３）が差し込まれており、ゆえに、設置された枝管（２）の中の、冷水が温水に入れ換わる。Operation 1 of the hot water supply device, hot water flows from the hot water supply main (3) to the open faucet (4 ") among the many faucets, but the hot water main (3) is thin and lacks hot water supply Inevitably, the hot water in the other branch pipe (2), and if it is cold, water will flow in. The other branch pipes (2) installed in the required number are all inserted with the hot water supply main pipe (3). Therefore, the cold water in the installed branch pipe (2) is replaced with hot water.

給湯装置本体の動作２複数又は全部の給湯蛇口（４）が開かれて、給湯不足の場合は、バイバス弁（８）が開き給湯不足を補う。バイバス弁は調整された以上の負圧で開き、流量の少ない時は、給湯本管（３）の流れを優先する。Operation 2 of Hot Water Supply Main Body When a plurality or all of the hot water supply taps (4) are opened and the hot water supply is insufficient, the bypass valve (8) is opened to compensate for the shortage of hot water supply. The bypass valve opens with a negative pressure higher than the adjusted pressure, and when the flow rate is small, the flow of the hot water supply main (3) is given priority.

給湯装置本体の動作３すべての給湯蛇口（４）が閉ざされ、給湯枝管（２）や、給湯溜まり（４）の中の温水が、冷水になってしまった場合の動作。
この給湯装置本体（１）は、温度開閉弁（９）と、逆止弁（１０）を介し、給水装置（１１）に、接続即湯装置の働きを助ける。Operation 3 of Hot Water Supply Device Operation when all of the hot water supply taps (4) are closed and the hot water in the hot water supply branch pipe (2) and the hot water supply reservoir (4) has become cold water.
This hot water supply apparatus main body (1) assists the function of the connected hot water supply apparatus to the water supply apparatus (11) through the temperature on-off valve (9) and the check valve (10).

この給水装置（１１）の、給水入り口（１２）の先は、細く絞られ、ベンチュリー効果で即湯装置（１）内の冷水を抜き取り、必然的に温水が流れ込み、入れ替わった部分すべてを温める。
これにより即湯が可能となる。The tip of the water supply inlet (12) of the water supply device (11) is narrowed down and the cold water in the instant hot water device (1) is drawn out by the venturi effect, and hot water flows inevitably, and all the replaced parts are heated.
This allows instant hot water.

（イ）即湯装置により、蛇口から湯が出るまでの、無駄水を無くす。
（ロ）給湯蛇口、枝管、が常に温まり、凍結を防ぐ。
（ハ）熱源以外の、経費がいらない。
（ニ）配管、保温の、単純化。
（ホ）給水管に、温度開閉弁の設定以下の温水が流れ、水温を上げ、結露、凍結を防ぐ。(I) Eliminate wasted water until hot water comes out of the faucet with an instant hot water device.
(B) The hot water faucet and branch pipe are always warmed to prevent freezing.
(C) There is no need for expenses other than heat sources.
(D) Simplification of piping and heat insulation.
(E) Warm water below the temperature on / off valve setting flows into the water supply pipe, raising the water temperature to prevent condensation and freezing.

は即湯装置（１）と給水装置（９）の、作動概念図である。These are operation | movement conceptual diagrams of an instant hot water apparatus (1) and a water supply apparatus (9).

本発明、即湯装置の使用例の一つを示す。
仮に、一般家庭、三ヶ所給湯を例として、早朝、熱源の給湯器以外、すべての配管が、冷え切った状態の時、トイレの洗浄水を流す、この時、即湯装置（１）に接続された、給水装置（１１）の中のベンチュリーの作用で、即湯装置（１）及び給湯枝管（２）給湯本管（３）内の冷水を、給水配管側に抜き取り、温水と入れ替え、即湯状態となる。One example of use of the present invention and instant hot water apparatus is shown.
For example, in the case of a general household, hot water supply at three places, in the early morning, when all the pipes are cold, except for the water heater of the heat source, flush the toilet flushing water. At this time, connect to the hot water supply device (1) By the action of the venturi in the water supply device (11), the cold water in the immediate hot water device (1) and the hot water supply branch pipe (2) hot water supply main pipe (3) is extracted to the water supply pipe side and replaced with hot water, Immediate hot water.

また、大量の水が、給水装置（１１）を通過しても、温度開閉弁（９）が、設定温度で作用、給水装置に無駄な温水の、流れ込みを、止める。Further, even if a large amount of water passes through the water supply device (11), the temperature on-off valve (9) acts at the set temperature and stops the flow of wasted warm water into the water supply device.

これにより蛇口から、温水が出るまで捨てられていた水が、他に使用できる例である。This is an example where water that has been thrown away from the faucet until hot water comes out can be used elsewhere.

即湯装置（１）の応用例として、即湯装置の給湯受け口（６）、を給水装置（１１）、の給水装置出口（１３）に、接続することにより、前説明の作用が、給水配管側にも働き給水枝管内の水の停滞を無くし、水質の低下、凍結、を防止する。As an application example of the immediate hot water supply device (1), the hot water supply receiving port (6) of the immediate hot water supply device is connected to the water supply device outlet (13) of the water supply device (11), so that the above-described operation can be achieved. It also works on the side to eliminate the stagnation of water in the water supply branch pipe and prevent water quality deterioration and freezing.

Claims

A device that replaces other fluid in a branch pipe when one of the branch pipes containing fluid flows out.

A device for removing stagnant water on the hot water supply side by the flow of water supply.
