It was devised to provide a hot water heater with good quality, and its gist was to form a fine thread inside the exhaust pipe of the bathtub, with the same diameter up to almost the center and gradually decreasing in diameter above it. A metal pipe extending in the vertical direction is fitted, a water supply pipe is connected to the lower end of the pipe, and a water discharge pipe is connected to the other upper end, and the metal pipe is fitted below the metal pipe to approximately match the shape of the lower end. A water heater using exhaust heat from a bathtub is characterized in that a ring-shaped water drip tray is arranged.
以下、図示の実施例に基づいて本考案を詳細に説明する
と、図において1は浴槽で、ガス又は石油等を燃料とす
る風呂釜2と循環パイプ3で連結されている。Hereinafter, the present invention will be described in detail based on the illustrated embodiment. In the figure, reference numeral 1 denotes a bathtub, which is connected by a circulation pipe 3 to a bathtub 2 that uses gas, oil, or the like as fuel.
4は上記風呂2の排気側と連結した一次排気筒で、その
上方には二次排気筒5が接続され、両者4.5の間には
逆風比6が介装されて、風呂釜2に発生した排気ガスが
屋外に排気されるよう構成した従来公知のものである。A primary exhaust pipe 4 is connected to the exhaust side of the bath 2, and a secondary exhaust pipe 5 is connected above it, and a back wind ratio 6 is interposed between the two 4. This is a conventionally known device configured so that the generated exhaust gas is exhausted outdoors.
7は上記−次排気筒4内に嵌装した金属製パイプで、緻
密な螺施状で、且つそのほぼ中央まで同一径とし、その
上方は次第に小径となるように形成されており、上下方
向に延び、下端7aから供給された水を一次排気筒4内
の排気熱によって暖め、その上端7bから温水として吐
出するためのものである。Reference numeral 7 denotes a metal pipe fitted into the secondary exhaust pipe 4, which has a finely threaded shape and has the same diameter up to almost the center, and is formed so that the diameter gradually becomes smaller in the upper part. This is for warming the water supplied from the lower end 7a by the exhaust heat in the primary exhaust pipe 4, and discharging it as hot water from the upper end 7b.
このように緻密な螺施状としたのは、−次排気筒4内の
熱を十分に吸収するために、外部に晒される表面積をで
きる限り広くするためであり、また約上半分を除々に小
径としたのは、ここでのパイプの長さを短くして温水を
加熱保温しつつより速く吐出させるためである。The purpose of this dense spiral pattern is to make the surface area exposed to the outside as wide as possible in order to sufficiently absorb the heat inside the secondary exhaust stack 4. The reason why the diameter is small is to shorten the length of the pipe so that hot water can be heated and kept warm while being discharged faster.
すなわち、−次排気筒4内の温度は下方が高く、上方に
行くに従い低くなるので、この高温部分での滞留時間を
長くし、低温部分では熱を放射することなく素速く吐出
させ、更に加熱する水の量を増大させているのである。In other words, the temperature inside the secondary exhaust stack 4 is high at the bottom and decreases as it goes upward, so the residence time in this high-temperature area is lengthened, and the low-temperature area is quickly discharged without radiating heat. This increases the amount of water that can be used.
8は給水ホースで、一端は水道蛇口9又は水タンク(図
示せず)等の水の供給源に、他端は上記金属製パイプ7
の下端7aに連結されており、10は吐水パイプで、金
属製パイプ7の上端7bに連結され、他端は給湯場所、
図示の実施例では浴槽1に臨んでいる。8 is a water supply hose, one end of which is connected to a water supply source such as a water faucet 9 or a water tank (not shown), and the other end is connected to the metal pipe 7 mentioned above.
10 is a water discharge pipe connected to the upper end 7b of the metal pipe 7, and the other end is a hot water supply place,
In the illustrated embodiment, the bathtub 1 is faced.
而して、水道蛇口9から吐出された水は、給水ホ−ス8
内を流れて金属製パイプ7に供給され、この金属製パイ
プ7内を流れることにより一次排気筒4内の熱を吸収し
て温水化し、吐水パイプ10から浴槽1等に吐出される
のである。Therefore, the water discharged from the water faucet 9 is transferred to the water supply hose 8.
The water flows through the metal pipe 7 and is supplied to the metal pipe 7. As the water flows through the metal pipe 7, it absorbs the heat in the primary exhaust pipe 4, heats the water, and discharges the water from the water discharge pipe 10 into the bathtub 1 and the like.
11は上記金属製パイプ7の下方に配置された水滴受で
、金属製パイプ7内を水が流れる時、このパイプ7が冷
やされるが故に、この表面に露を結び、これが大きくな
って滴下する水滴を受け、これを排水パイプ11 aか
ら外部に排水させるためのものであり、金属製パイプ7
の下端のパイプ形状に合わせ略リング状に形成されてい
る。Reference numeral 11 denotes a water drip tray placed below the metal pipe 7. When water flows through the metal pipe 7, since the pipe 7 is cooled, dew forms on its surface, which grows and drips. The metal pipe 7 is for receiving water droplets and draining them to the outside from the drain pipe 11a.
It is formed into a substantially ring shape to match the shape of the pipe at the lower end.
すなわち水滴の大部分は金属製パイプ7の下端のパイプ
に集まり、ここから滴下すると考えられるので、この水
滴の風呂釜2への侵入を防止し、しかもここで排気ガス
の流出を遮断してしまうことを防止しているのである。In other words, since most of the water droplets are thought to collect on the pipe at the lower end of the metal pipe 7 and drip from there, it is possible to prevent these water droplets from entering the bath pot 2, and also to block the outflow of exhaust gas here. This is what we are trying to prevent.
而して、本考案の使用例は、浴槽1内に通常の定水量の
7割程度の水を張り、風呂釜2を点火すると・もに水道
蛇口9を開く。Accordingly, in an example of the use of the present invention, the bathtub 1 is filled with about 70% of the normal amount of water, the bathtub 2 is ignited, and the water faucet 9 is opened.
そして、この水道蛇口9から吐出された水を浴槽1内に
流入させ、これを定水量となすのであるが、この時、こ
の水は一次排気筒4内において金属製パイプ7内を流れ
ることによりここで加熱され、温水となって吐水パイプ
10から吐出され、通常の風呂釜のみで沸す時間に比べ
て大幅な時間の短縮ができるのである。The water discharged from the faucet 9 is then made to flow into the bathtub 1 to provide a constant amount of water.At this time, this water flows through the metal pipe 7 in the primary exhaust pipe 4. Here, the water is heated and turned into hot water, which is then discharged from the water spouting pipe 10, making it possible to significantly shorten the time required to boil the water using only a normal bath pot.
本考案は上記のような構成であるので、水道蛇口9等か

なく、温度の高い下方においては滞留時間が長く、温度

のより有効的な利用が図られ、より経済的で効率的とな
る。Since the present invention has the above-mentioned configuration, the water discharged from the water faucet 9 etc. is warmed in the metal pipe 7 by the exhaust heat of the bath pot 2, and not only can this heat be sufficiently absorbed, but also The residence time is long in the lower part where the temperature is higher, and this time gradually becomes shorter in the upper part where the temperature is lower, so that the exhaust heat can be used more effectively, making it more economical and efficient.

排出に支障を来すことはないといった諸効果がある。Furthermore, most of the water vapor contained in the exhaust gas adheres to the metal pipe 7 as dew and drips, but these water droplets are discharged to the outside by the water drip pan 11 and enter the bathtub 2. Not only is there no problem, but this water drip tray 11 has various effects such that it does not interfere with exhaust gas discharge.
