Description
【０００１】[0001]
本考案は貯湯槽に関し、特に太陽熱利用温水器などに用いられる貯湯槽に関す る。 The present invention relates to a hot water storage tank, and more particularly to a hot water storage tank used for a solar water heater.
【０００２】[0002]
太陽熱利用温水器は、集熱器と貯湯槽を熱媒が循環する配管で接続すると共に 、この貯湯槽に、貯湯槽内の湯を出湯する給湯口と、貯湯槽内に市水を供給する 給水口とを設けて構成される。このような従来の太陽熱利用温水器の貯湯槽を図 ２に示す。図２（ａ）は、貯湯槽を正面（前面側）から見たときの断面図であり 、図２（ｂ）は、貯湯槽を側面側から見たときの断面図である。貯湯槽１の側壁 には、給水口２と給湯口３が設けられている。給水口２には、給水栓４が設けら れた給水管５が接続され、給湯口３には、給湯栓６が設けられた給湯管７が接続 されている。また、貯湯槽１内では、給水口２に貯湯槽１内の水が所定水位以下 に下がったときに給水するボールタップ８が設けられ、給湯口３には、採湯口１ ０を有すフロート式採湯管９が設けられている。 The solar water heater connects the collector to the hot water storage tank with piping that circulates the heating medium, and supplies hot water to the hot water storage tank with a hot water outlet and hot water in the hot water storage tank. And a water supply port. Fig. 2 shows a hot water storage tank for such a conventional solar water heater. 2 (a) is a cross-sectional view of the hot water storage tank as viewed from the front (front side), and FIG. 2 (b) is a cross-sectional view of the hot water storage tank as viewed from the side. A water supply port 2 and a hot water supply port 3 are provided on the side wall of the hot water storage tank 1. A water supply pipe 5 provided with a water supply tap 4 is connected to the water supply port 2, and a hot water supply pipe 7 provided with a hot water supply plug 6 is connected to the hot water supply port 3. Further, in the hot water storage tank 1, a ball tap 8 for supplying water when the water in the hot water storage tank 1 drops below a predetermined water level is provided in the water supply port 2, and the hot water supply port 3 is a float type having a hot water intake port 10. A hot water pipe 9 is provided.
【０００３】 このような貯湯槽１では、給水栓４を開いて給水口２から水を貯湯槽１内に給 水し、所定水位以上になると、ボールタップ８で給水を停止する。この場合、給 水栓４は開いたままにしておく。貯湯槽１内に給水した水を集熱器（不図示）と の間で循環させて昇温させる。昇温した湯を利用する場合、給湯栓６を開いてフ ロート式採湯管９と給湯管７を経由して給湯する。この場合、貯湯槽１内が所定 水位以下になれば、ボールタップ８が開いて再び給水する。このような給湯方式 は、一般にオーバーフロー給湯方式と呼ばれ、給湯された湯をボイラーなどの補 助加熱源で更に加熱して使用する場合に有効である。In such a hot water storage tank 1, the water tap 4 is opened to supply water from the water supply port 2 into the hot water storage tank 1, and when the water level reaches a predetermined level or higher, the water supply is stopped by the ball tap 8. In this case, the tap 4 is left open. The water supplied to the hot water storage tank 1 is circulated between a water collector (not shown) to raise the temperature. When using the heated water, the hot water tap 6 is opened and hot water is supplied through the float type hot water collecting pipe 9 and the hot water supply pipe 7. In this case, when the inside of the hot water storage tank 1 reaches a predetermined water level or lower, the ball tap 8 is opened to supply water again. Such a hot water supply method is generally called an overflow hot water supply method, and is effective when the heated hot water is further heated by an auxiliary heating source such as a boiler.
【０００４】 このオーバーフロー給湯方式の他にロット給湯方式がある。ロット給湯方式は 、給水栓４を開いて水を給水口２から貯湯槽１内に給水し、所定水位以上になる と、ボールタップ８で給水を停止する。給水が停止したら、給水栓４を閉じる。 貯湯槽１内に給水した水を集熱器（不図示）との間で循環させて昇温させる。昇 温した湯を利用する場合、給湯栓６を開いてフロート式採湯管９と給湯管７を経 由して給湯する。この場合、給湯中に貯湯槽１内が所定水位以下になっても、給 水されないことから、昇温した高温な湯だけを使用でき、風呂への落とし込みに 有効である。In addition to this overflow hot water supply method, there is a lot hot water supply method. In the lot hot water supply system, the water tap 4 is opened to supply water from the water supply port 2 into the hot water storage tank 1, and when the water level reaches a predetermined level or higher, the water supply is stopped by the ball tap 8. When the water supply is stopped, the water tap 4 is closed. The water supplied to the hot water storage tank 1 is circulated between a heat collector (not shown) to raise the temperature. When using the heated water, the hot water tap 6 is opened, and hot water is supplied through the float type hot water pipe 9 and the hot water pipe 7. In this case, even if the inside of the hot water storage tank 1 is below the predetermined water level during hot water supply, water is not supplied, so only the hot water with a high temperature can be used, which is effective for dropping into the bath.
【０００５】 いずれの給湯方式でも、フロート式採湯管９は、貯湯槽１内の水位に従って上 下動する。In any of the hot water supply methods, the float type hot water collecting pipe 9 moves up and down according to the water level in the hot water storage tank 1.
【０００６】[0006]
ところが、従来の太陽熱利用温水器では、図２（ｂ）に示すように、側面から 見たときの貯湯槽１の形状が楕円形や方形のものである場合、貯湯槽１内の湯を ロット給湯すると、貯湯槽１内の湯が少なくなった場合、フロート式採湯管９の 採湯口１０が貯湯槽１の底部に接触し、貯湯槽１の底面と採湯口１０の摩擦抵抗 によって、フロート式採湯管９がそれ以上移動できなくなり、貯湯槽１内の前面 側に貯溜する湯を採湯できないという問題があった。 However, in the conventional solar water heater, when the shape of the hot water storage tank 1 when viewed from the side is elliptical or rectangular as shown in Fig. 2 (b), the hot water in the hot water storage tank 1 is When the amount of hot water in the hot water storage tank 1 becomes low when the hot water is supplied, the hot water tap 10 of the float type hot water tap pipe 9 contacts the bottom of the hot water tap tank 1, and the bottom surface of the hot water tap tank 1 and the hot water tap 10 cause frictional resistance. There was a problem that the hot water pipe 9 could not be moved any more, and the hot water stored in the front side of the hot water storage tank 1 could not be taken.
【０００７】 特に、太陽熱利用温水器は、屋根上などの傾斜面に設置されるものであり、上 述のような残湯がしばしば発生する。Particularly, the solar water heater is installed on an inclined surface such as a roof, and the residual hot water as described above is often generated.
【０００８】 なお、貯湯槽１が円筒状のものである場合は、フロート式採湯管９の採湯口１ ０は貯湯槽１の最下部で貯湯槽１の底部に接触することから、このような問題は 発生しない。When the hot water storage tank 1 has a cylindrical shape, since the hot water tap 10 of the float type hot water tapping pipe 9 contacts the bottom of the hot water tap tank 1 at the bottom of the hot water tap tank 1, Problem does not occur.
【０００９】[0009]
本考案に係る太陽熱利用温水器は、このような従来技術の問題点に鑑みてなさ れたものであり、その特徴とするところは、集熱器と貯湯槽を熱媒が循環する配 管で接続すると共に、前記貯湯槽に給水口と給湯口を設けた太陽熱利用温水器に おいて、前記貯湯槽の側壁に給湯口を設け、この給湯口にフロート式採湯管を接 続し、前記貯湯槽の底部に、この貯湯槽の水位が低下したときに、前記フロート 式採湯管が摺動する突起部を、前記貯湯槽の前面側が低くなるように傾斜して設 けた点にある。 The solar water heater according to the present invention has been made in view of such problems of the conventional technology, and is characterized in that the heat medium is circulated between the heat collector and the hot water storage tank. In the solar water heater with the water supply port and the hot water supply port provided in the hot water storage tank, the hot water supply port is provided on the side wall of the hot water storage tank, and the float type hot water collecting pipe is connected to the hot water supply port. A protrusion is provided at the bottom of the hot water storage tank so that the float type hot water collecting pipe slides when the water level of the hot water storage tank is lowered so that the front side of the hot water storage tank is inclined.
【００１０】[0010]
上記のように構成すると、貯湯槽内の湯が減少した場合、フロート式採湯管は 貯湯槽の底部に設けた突起部に接触するが、この突起部は貯湯槽の前面側が低く なるように傾斜して形成されていることから、フロート式採湯管と突起部は摩擦 抵抗が小さく、もってフロート式採湯管の採湯口は、貯湯槽１内の水位の低下と 共に、徐々に貯湯槽の前面側に導かれる。もって、側面から見た形状が方形や楕 円形の貯湯槽を有する太陽熱利用温水器において、ロット給湯した場合でも、貯 湯槽内に残湯を生じることはなく、貯湯槽内の高温な湯を有効に利用することが できる。 With the above configuration, when the amount of hot water in the hot water storage tank decreases, the float type hot water collecting pipe comes into contact with the projection provided on the bottom of the hot water storage tank. Since the float type hot water collecting pipe and the protrusions have a small frictional resistance because it is formed in an inclined manner, the water collecting port of the float type hot water collecting pipe gradually decreases as the water level in the hot water storage tank 1 decreases. Is led to the front side of. Therefore, in a solar-powered water heater that has a storage tank that has a rectangular or elliptical shape when viewed from the side, even when lots of hot water are supplied, no hot water remains in the storage tank, and the hot water in the storage tank is effective. Can be used for.
【００１１】[0011]
以下、本考案の実施例を添付図面に基づき詳細に説明する。 なお、本考案に係る太陽熱利用温水器でも、集熱器と貯湯槽を熱媒が循環する 配管で接続すると共に、この貯湯槽に、貯湯槽内の湯を出湯する給湯口と、貯湯 槽内に市水を供給する給水口とを設けて構成される点は、従来の太陽熱利用温水 器と同じである。 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Also in the solar water heater according to the present invention, the heat collector and the hot water storage tank are connected by a pipe through which a heat medium circulates, and the hot water storage tank has a hot water supply port for tapping hot water from the hot water storage tank and a hot water storage tank. It is the same as the conventional solar water heater in that it is configured with a water supply port for supplying city water.
【００１２】 図１に、本考案に係る太陽熱利用温水器に用いられる貯湯槽の断面図を示す。 図１（ａ）は、貯湯槽１を正面側から見た場合の断面図であり、図１（ｂ）は、 貯湯槽１を側面側から見た場合の断面図である。FIG. 1 shows a cross-sectional view of a hot water storage tank used in a solar water heater according to the present invention. 1A is a cross-sectional view of the hot water storage tank 1 when viewed from the front side, and FIG. 1B is a cross-sectional view of the hot water storage tank 1 when viewed from the side surface.
【００１３】 貯湯槽１には、従来の貯湯槽と同様に、側壁に、給水口２と給湯口３を設け、 この給水口２に、給水栓４を設けた給水管５を接続し、給湯口２に給湯栓６を設 けた給湯管７を接続している。また、貯湯槽１内では、給水口２に貯湯槽１内の 水が所定水位以下に下がったときに給水するボールタップ８を設け、給湯口３に は、採湯口１０を有すフロート式採湯管９を設けている。なお、フロート式採湯 管とは、採湯口１０の近傍に浮子などから成るフロートを付けて、貯湯槽１の水 位の変動に応じて、採湯口１０の位置が移動する採湯管をいう。Like the conventional hot water storage tank, the hot water storage tank 1 is provided with a water supply port 2 and a hot water supply port 3 on the side wall, and a water supply pipe 5 provided with a water supply plug 4 is connected to the water supply port 2 to supply hot water. A hot water supply pipe 7 having a hot water supply plug 6 is connected to the mouth 2. Further, in the hot water tank 1, a ball tap 8 for supplying water when the water in the hot water tank 1 drops below a predetermined water level is provided at the water inlet 2, and at the hot water inlet 3, a float type hot water having a hot water inlet 10 is provided. A tube 9 is provided. The float type hot water collecting pipe is a hot water collecting pipe in which a float made of a float or the like is attached near the hot water collecting port 10 and the position of the hot water collecting port 10 moves according to the fluctuation of the water level in the hot water storage tank 1. .
【００１４】 本考案では、貯湯槽１の底部に、貯湯槽１の水位が低下したときに、フロート 式採湯管９が摺動する突起部１１を、貯湯槽１の前面側１ａが低くなるように傾 斜して設けている。この突起部１１は、フロート式採湯管９との摩擦抵抗をでき るだけ小さくするために、先端部が尖鋭状のものが望ましいが、先端部以外の形 状はいかなるものであってもよい。In the present invention, at the bottom of the hot water storage tank 1, the projection 11 on which the float type hot water collecting pipe 9 slides when the water level of the hot water storage tank 1 is lowered becomes lower on the front side 1a of the hot water storage tank 1. It is installed so as to be inclined. The protrusion 11 preferably has a sharp tip in order to reduce frictional resistance with the float type hot water collecting pipe 9 as much as possible, but any shape other than the tip may be used. .
【００１５】 また、この突起部１１は、貯湯槽１の前面側１ａが低くなるように傾斜して形 成されるが、この傾斜角度は、貯湯槽１内の水位が徐々に低下した場合でも、フ ロート式採湯管９が貯湯槽１の前面側１ａに移動できるような角度に設計すれば よい。すなわち、フロート式採湯管９は採湯口１０が自由移動できるようその途 中に蛇腹部９ａを設けており、この蛇腹部９ａの材質や厚みによっても、必要と される突起部１１の傾斜角度は大きく異なるが、蛇腹部９ａを例えばＥＰＤＭな どのゴム材質で形成した場合、貯湯槽１の底面に対して１５°程度の角度を持た せればよい。Further, the protrusion 11 is formed so as to be inclined so that the front surface side 1a of the hot water storage tank 1 is lowered, but this inclination angle is set even when the water level in the hot water storage tank 1 gradually decreases. The angle may be designed so that the float type hot water collecting pipe 9 can be moved to the front side 1a of the hot water storage tank 1. That is, the float type hot water collecting pipe 9 is provided with a bellows part 9a along the way so that the hot water collecting port 10 can freely move. However, when the bellows portion 9a is made of a rubber material such as EPDM, it may have an angle of about 15 ° with respect to the bottom surface of the hot water storage tank 1.
【００１６】 また、図１（ｂ）に示す実施例では、突起部１１の側面側から見た形状は、略 三角形状であるが、略三角形状に限らず、台形状のものであってもよく、さらに 扇形状のものであってもよい。特に、フロート式採湯管９は、蛇腹部９ａがある ことから、貯湯槽１の側壁面に対する角度を小さくなると移動しにくくなるので 、貯湯槽１の前面側の角度が大きくなるような扇形状の突起部１１は有効である 。In addition, in the embodiment shown in FIG. 1B, the shape of the protrusion 11 viewed from the side surface side is a substantially triangular shape, but the shape is not limited to a substantially triangular shape and may be a trapezoidal shape. Of course, it may be fan-shaped. In particular, since the float type hot water collecting pipe 9 has the bellows portion 9a, it becomes difficult to move when the angle with respect to the side wall surface of the hot water storage tank 1 becomes smaller, so that the angle of the front side of the hot water storage tank 1 becomes large. The protruding portion 11 of is effective.
【００１７】 このような突起部１１は、貯湯槽１と一体に形成するか、突起部１１を貯湯槽 １とは別体に形成して、貯湯槽１の底部や後壁に固定する。なお、貯湯槽１は、 通常、ポリエチレン樹脂などから成り、ブロー成型することによって形成される 。Such a projection 11 is formed integrally with the hot water storage tank 1, or the projection 11 is formed separately from the hot water storage tank 1 and fixed to the bottom portion or the rear wall of the hot water storage tank 1. The hot water storage tank 1 is usually made of polyethylene resin or the like and is formed by blow molding.
【００１８】[0018]
以上のように、本考案に係る太陽熱利用温水器によれば、貯湯槽の底部に、こ の貯湯槽の水位が低下したときに、フロート式採湯管が摺動する突起部を、貯湯 槽の前面側が低くなるように傾斜して設けたことから、フロート式採湯管の採湯 口は、貯湯槽１内の水位の低下と共に、徐々に貯湯槽の前面側に導かれる。もっ て、側面から見た形状が方形や楕円形の貯湯槽を有する太陽熱利用温水器におい て、ロット給湯した場合でも、貯湯槽内に残湯を生じることはなく、貯湯槽内の 高温な湯を有効に利用することができる。 As described above, according to the solar water heater according to the present invention, the bottom of the hot water storage tank is provided with the protrusion for sliding the float type hot water collecting pipe when the water level of the hot water storage tank drops. Since the front surface of the float is inclined so as to be low, the hot water intake port of the float type hot water collecting pipe is gradually guided to the front surface side of the hot water storage tank as the water level in the hot water storage tank 1 decreases. Therefore, in a solar-powered water heater that has a storage tank that has a rectangular or elliptical shape when viewed from the side, no residual hot water is generated in the storage tank even when a lot of hot water is supplied. Can be used effectively.
