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]
従来の太陽熱利用温水器などに用いられる貯湯槽を図３および図４に示す。図 ３は、貯湯槽１を正面から見たときの断面図であり、図４は貯湯槽１を側面から 見たときの断面図である。図３および図４において、１は貯湯槽本体、２は貯湯 槽１内の湯を外部へ供給する給湯口、３は市水を貯湯槽１内へ供給する給水口で ある。給水口３には、ボールタップ弁４が設けられており、貯湯槽１内の水位が 所定以下になったときには、弁を開いて貯湯槽１内へ給水し、貯湯槽１内の水位 が所定以上になったときには弁を閉じて給水を停止するように構成されている。 また、給湯口２は、貯湯槽１側壁の比較的高所に設けられており、貯湯槽１内高 所の高温な湯を採湯できるように構成されている。さらに、給水口３には、給水 口３から供給される市水が貯湯槽１内の温水と混合しないように導水管５を介し て貯湯槽１の底部に導かれるように構成されている。 A hot water storage tank used for a conventional solar water heater or the like is shown in FIGS. 3 and 4. FIG. 3 is a sectional view of the hot water storage tank 1 when viewed from the front, and FIG. 4 is a sectional view of the hot water storage tank 1 when viewed from the side. In FIGS. 3 and 4, 1 is a hot water tank body, 2 is a hot water supply port for supplying hot water in the hot water storage tank 1 to the outside, and 3 is a water supply port for supplying city water to the hot water storage tank 1. A ball tap valve 4 is provided at the water supply port 3, and when the water level in the hot water storage tank 1 falls below a predetermined level, the valve is opened to supply water into the hot water storage tank 1 so that the water level in the hot water storage tank 1 is above a predetermined level. When this happens, the valve is closed to stop the water supply. The hot water supply port 2 is provided at a relatively high position on the side wall of the hot water storage tank 1, and is configured to be able to draw hot water at a high position inside the hot water storage tank 1. Further, the water supply port 3 is configured so that the city water supplied from the water supply port 3 is guided to the bottom of the hot water storage tank 1 via a water conduit 5 so as not to mix with the hot water in the hot water storage tank 1.
【０００３】[0003]
ところが、この従来の貯湯槽では、貯湯槽１が、側面から見たときの断面形状 が円筒状のものである場合は、導水管５を設けることによって、市水を貯湯槽１ 内の底部に導くことができるが、図４に示すように、貯湯槽１の断面形状が長円 形や楕円形である場合は、貯湯槽１を屋根上などに傾斜して設置すると、導水管 ５を鉛直方向に設けても、導水管５の下端開口部は、貯湯槽１内の底部近傍には 達しないという問題があった。すなわち、太陽熱利用温水器は、通常オーバーフ ローによって給湯を行うものが多いが、給水口３から給水される低温の水と貯湯 槽１内の湯を混合させないようにすることが重要であり、高温の湯の層と低温の 水の層の温度成層を作ることが重要であるが、図４に示すような従来の貯湯槽で は、断面形状が長円形や楕円形である場合、貯湯槽１内に良好な温度成層を形成 することができず、その結果給湯口２から高温な湯を取り出すことができないと いう問題があった。 However, in this conventional hot water storage tank, when the hot water storage tank 1 has a cylindrical cross-sectional shape when viewed from the side, the water pipe 5 is provided so that city water can flow to the bottom of the hot water storage tank 1. As shown in Fig. 4, when the hot water storage tank 1 has an oval or elliptical cross-section, if the hot water storage tank 1 is installed at an angle on the roof, the water conduit 5 will be vertically installed. Even if it is installed in the direction, there is a problem that the lower end opening of the water conduit 5 does not reach the vicinity of the bottom in the hot water storage tank 1. That is, many solar water heaters normally supply water by overflow, but it is important to prevent the low temperature water supplied from the water supply port 3 from mixing with the hot water in the hot water storage tank 1, It is important to create a temperature stratification of the hot water layer and the low temperature water layer, but in the conventional hot water storage tank as shown in Fig. 4, when the cross-sectional shape is oval or elliptical, the hot water storage tank 1 There was a problem that good temperature stratification could not be formed inside, and as a result hot water could not be taken out from the hot water supply port 2.
【０００４】[0004]
本考案に係る貯湯槽は、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、貯湯槽内に給水するための給水口と、貯湯槽内 の湯を外部へ給湯するための給湯口が設けられた貯湯槽において、前記給水口に 給水口から給水される水を前記貯湯槽の底部に導く導水管を設けると共に、この 導水管と対峙する貯湯槽底部に、この貯湯槽の背面側から前面側に向かう水の流 路を設けた点にある。 The hot water storage tank according to the present invention has been made in view of such problems of the conventional technology, and is characterized by a water supply port for supplying water into the hot water storage tank and a hot water in the hot water storage tank. In a hot water storage tank provided with a hot water supply port for supplying hot water to the outside, a water conduit for guiding the water supplied from the water supply port to the bottom of the hot water storage tank is provided at the water supply port, and the bottom of the hot water storage tank facing the water conduit is also provided. In addition, a water flow path from the back side to the front side of this hot water storage tank is provided.
【０００５】[0005]
上記のように構成することにより、断面形状が長円形や楕円形である貯湯槽で も、給水口から給水される冷水を確実に貯湯槽底部に導くことができ、もって貯 湯槽内に温度成層を形成して、給湯口から高温な湯を取り出すことができる貯湯 槽となる。 With the above configuration, even in a hot water storage tank having an oval or elliptical cross-sectional shape, the cold water supplied from the water supply port can be reliably guided to the bottom of the hot water storage tank, and thus the temperature stratification in the hot water storage tank can be achieved. To form a hot water storage tank that can take hot water from the hot water supply port.
