Description

【考案の詳細な説明】〔産業上の利用分野〕この考案は、常時一定温度の湯が得られるよう
にした温水ボイラーに関するものである。[Detailed description of the invention] [Industrial field of application] This invention relates to a hot water boiler that can always provide hot water at a constant temperature.

[Conventional technology]

一般に温水ボイラーは、(イ)保有水量の少ない瞬
間湯沸器式、(ロ)貯湯式、(ハ)瞬間湯沸器式と貯湯タ
ンクとの組合わせの３種に大別できる。(ロ)および
(ハ)は短時間の過負荷に対応させるためのものであ
る。 In general, hot water boilers can be roughly divided into three types: (a) instantaneous water boiler types that hold a small amount of water, (b) hot water storage types, and (c) a combination of instantaneous water heater types and hot water storage tanks. (b) and
(C) is for responding to short-term overloads.

[The problem that the idea aims to solve]

然るに、従来のものにおいては、給湯時、強制
循環あるいは加熱による対流によつて低温の補給
水を全体に均一に混合してしまう。従つて給湯に
際し、温度降下を生じて貯湯した意義を半減する
という欠点があつた。 However, in conventional systems, during hot water supply, low-temperature make-up water is uniformly mixed throughout the tank by forced circulation or convection caused by heating. Therefore, when hot water is supplied, the temperature drops, which reduces the significance of storing hot water in half.

一方、高温水を上方に、低温水を下方に貯えた
水槽内では、機械的あるいは加熱等による強制的
循環を行わない限り、比較的安定した温度差境界
面を保つことが知られている。この現象は日常の
浴槽内の現象でも容易に推察できることである。 On the other hand, it is known that in an aquarium in which high-temperature water is stored above and low-temperature water is stored below, a relatively stable temperature difference boundary is maintained unless forced circulation is performed mechanically or by heating. This phenomenon can be easily inferred from everyday phenomena in bathtubs.

It can be simplified and simplified.

〔Example〕

以下、この考案の実施例を図面に基づいて説明
する。 Hereinafter, embodiments of this invention will be described based on the drawings.

とそれぞれ連通している。 The upper header 1 and the lower header 2 form a large number of water pipes 3.
are connected. A combustion chamber 4 is formed inside the water tube group. A combustion device 5 is installed inside the lower header 2.
is installed. 6 in the figure is the casing,
A flue 7 is provided in a part of it. A hot water storage tank 8 is provided on the upper header 1 so as to be formed integrally with the upper plate of the upper header as a bottom plate. An insertion pipe 9 is arranged in the hot water storage tank 8,
One end communicates with the upper header 1, and the other end communicates with the upper part of the hot water storage tank.

環ポンプ１３とが設けられている。 A hot water supply pipe 10 is connected to the upper part of the hot water storage tank 8. The lower part of the hot water storage tank 8 and the lower header 2 are connected by a circulation pipe 11. A temperature controller 12 for controlling the combustion device 5 and a circulation pump 13 are provided in the circulation pipe 11 .

の上部に接続されている。 Further, a water supply tank 20 is disposed above the outlet opening of the hot water supply pipe 10, and the water supply tank 20 is constructed so that the stored water level is always constant. The lower end of the water supply pipe 14 extending from the bottom of the water supply tank 20 is connected to the circulation pipe 11.
connected to the top of the

図中１５は逃がし管、１６は流量調節弁であ
る。 In the figure, 15 is a relief pipe, and 16 is a flow rate control valve.

次に、この考案の温水ボイラーの動作を説明す
る。 Next, the operation of the hot water boiler of this invention will be explained.

この温水ボイラーにおいて、給湯管１０下流で
コツク等を開けると、給水タンク２０と給湯管１
０の水頭差、即ち、給水タンク２０内の水面高さ
と給湯管１０の出口開口部との高さの差に起因す
る圧力差により、給湯管１０から出湯を始める。 In this hot water boiler, when the pot etc. is opened downstream of the hot water pipe 10, the water tank 20 and the hot water pipe 1 are opened.
Hot water begins to be discharged from the hot water pipe 10 due to a water head difference of 0, that is, a pressure difference caused by the difference in the height of the water surface in the water tank 20 and the height of the outlet opening of the hot water pipe 10.

今、給水温度20℃で流量調節弁１６を調節（流

貯湯タンク８の方へも流入して、80℃の湯と20℃
の水との境界面（図中Ｈ）はだんだんと上昇す
る。そして、Q₁＜Q₂になる貯湯タンク８内の境
界面Ｈはだんだんと下降していく。 Now, if we consider the case where we want to constantly obtain hot water at 80°C from the hot water pipe 10 by adjusting the flow rate control valve 16 (flow rate Q ₂ ) at a water supply temperature of 20°C, when the hot water supply amount Q ₁ is smaller than the flow rate Q ₂ , 80°C ℃ hot water is gradually stored from the upper part of the hot water storage tank 8, and finally the temperature controller 12 is activated and the combustion device 5 stops combustion. When the hot water supply amount Q ₁ temporarily becomes larger than Q ₂ (short-term overload), water at 20°C also flows from the water supply pipe 14 toward the hot water storage tank 8, and becomes hot water at 80°C. 20℃
The interface with water (H in the figure) gradually rises. Then, the boundary surface H in the hot water storage tank 8, where Q ₁ <Q ₂ , gradually descends.

尚、この温水ボイラーにおいて、より高い出湯
圧が必要であれば、給水タンク２０をより高い位
置に取付ければよい。 In addition, in this hot water boiler, if a higher hot water output pressure is required, the water supply tank 20 may be installed at a higher position.

きるといつた効果がある。 As explained above, this idea connects one end of the insertion tube to the upper header and the other end to the upper part of the hot water storage tank, connects the lower part of the hot water storage tank and the lower header with a circulation pipe, and Since the water supply pipe is connected to the water supply pipe, an interface between high-temperature water and cold water is formed in the hot water storage tank, and hot water can be stored as high-temperature water without mixing with make-up water. can be supplied. Moreover, the pressure of hot water coming out of the hot water supply pipe is obtained by the difference in water head between the water supply tank and the outlet opening of the hot water supply pipe, so hot water can be dispensed without a pump for hot water supply. The top plate of the header is shared with the bottom plate of the hot water storage tank installed above it, and an insertion pipe is provided in the hot water storage tank, one end of which communicates with the upper header and the other end with the upper part of the hot water storage tank, and the inside of the tank is connected. Since the structure is included in the structure, it is more compact and has a simpler structure than the conventional one, and has the advantage of being able to reduce manufacturing costs.
