本発明はシスターンと、貯湯槽と、熱源をセパ
レートした貯湯式給湯システムに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hot water storage type hot water supply system in which a cistern, a hot water storage tank, and a heat source are separated.
一般に貯湯式給湯システムとしては第５図ａに
示すように構成され、貯湯槽２９に熱交換器３０

湯槽２９の上部より出湯するようになつている。
なお、図中の３１はバーナを示す。この貯湯式給
湯システムとしては貯湯槽２９内の湯を一定温度
たとえば80℃まで強制または自然循環させつつ加
熱し、沸き上げる方式がほとんどである。この場
合には第５図ｂに示すように熱交換器３０への入
口湯温t2が加熱時間経過とともに上昇してくるこ
とになる。なお、図中のt1は貯湯槽２９内湯温を
示す。したがつて、対数平均温度差が低下するの
で、時間経過とともに沸き上げ効率が低下をきた
すものとなる。 Generally, a hot water storage type hot water supply system is constructed as shown in FIG.
In combination, water is supplied from the lower part of the hot water storage tank 29 and hot water is discharged from the upper part of the hot water storage tank 29.
Note that 31 in the figure indicates a burner. Most hot water storage type hot water supply systems employ a method of heating hot water in a hot water storage tank 29 to a constant temperature, for example, 80° C., while forced or natural circulation. In this case, as shown in FIG. 5b, the inlet hot water temperature t2 to the heat exchanger 30 will rise as the heating time elapses. Note that t 1 in the figure indicates the hot water temperature in the hot water storage tank 29. Therefore, since the logarithmic average temperature difference decreases, the boiling efficiency decreases over time.
通常貯湯式給湯システムは相当に工夫しても効
率が75〜80％程度が一般的であるのに対し、瞬間
式給湯システムの場合は、熱交換器の入口湯温が
常に水温であるので、85〜90％という高効率化の
達成は容易である。 Normal hot water storage type hot water systems generally have an efficiency of around 75-80% even with considerable efforts, whereas in the case of instantaneous hot water systems, the water temperature at the inlet of the heat exchanger is always the water temperature. It is easy to achieve high efficiency of 85-90%.
本発明の貯湯式給湯システムはこのようなこと
から従来の貯湯給湯システムの機能を有しつつ高
効率化（85〜90％）を実現することをひとつの目
的としたものである。具体的には循環加熱タイプ
でなく、高温湯を貯湯槽に貯湯させる方式であ
る。つまり、熱交換器への入口湯温を常に水温状
態に保つことである。 For this reason, one of the purposes of the hot water storage type hot water supply system of the present invention is to achieve high efficiency (85 to 90%) while having the functions of the conventional hot water storage hot water supply system. Specifically, it is not a circulating heating type, but a method in which high-temperature hot water is stored in a hot water tank. In other words, the temperature of the inlet water to the heat exchanger must always be maintained at the water temperature.
本発明のもうひとつの目的としては次の点にあ
る。一般的に貯湯式給湯システムは、貯湯量が多
量（たとえば200以上）であり、低インプツト
能力のものが多い。この場合は沸き上げ時間を長
く必要とするとともに、短時間に使い果した場合
に、さらに、もう少しだけ高温湯が必要なときで
も貯湯量の切替えがないので多量に沸き上げねば
ならず沸き上げ時間を長く要し、湯切れ状態にな
る。 Another object of the present invention is as follows. In general, hot water storage type hot water systems have a large amount of hot water storage (for example, 200 or more) and often have low input capacity. In this case, it takes a long time to boil the water, and even if the hot water is used up in a short period of time, and even if a little more high-temperature water is needed, there is no change in the amount of hot water stored, so a large amount of hot water must be boiled, and the boiling time is longer. It takes a long time and the water runs out.
本発明の貯湯式給湯システムは低インプツト能
力の熱源とし、多量貯湯と少量貯湯の切替えを可
能にするとともに、給湯中に高温湯を連続的に貯
湯することを可能とし、貯湯量の設定を少なく
（たとえば120以下）することと、必要量の沸き
上げを可能にすることにある。 The hot water storage type hot water system of the present invention uses a heat source with a low input capacity, enables switching between large and small amounts of hot water storage, and also allows continuous storage of high temperature hot water during hot water supply, making it possible to reduce the setting of the amount of hot water stored. (for example, 120 or less) and to be able to boil the required amount.
さらに本発明の他の目的は次の点にある。すな
わち従来の貯湯式給湯システムは第５図ａのよう
に構成されていることから出湯を開始すれば貯湯
槽２９の下部より低温水が流水する。したがつて

のとなる。第３図のａの如きである。（一般的に
有効出湯量と表現する。）本発明はこの点をも改
良するものであり、有効出湯量の拡大をも目的と
したものである。 Furthermore, other objects of the present invention are as follows. That is, since the conventional hot water storage type hot water supply system is configured as shown in FIG. Therefore, a temperature distribution will occur under conditions where the entire capacity is used up. It is like a in Fig. 3. (Generally expressed as effective hot water output amount.) The present invention also improves this point and aims to expand the effective hot water output amount.
さらに、この種の給湯システムにおいては給湯
負荷パターンが各種考えられるものである。した
がつて、通常の給湯負荷パターンでない場合を考
慮すると貯湯槽内の湯温を長時間保つ（場合によ

ることを目的としたものである。 Furthermore, in this type of hot water supply system, various hot water supply load patterns are possible. Therefore, considering cases where the hot water supply load pattern is not normal, it is necessary to maintain the temperature of the hot water in the hot water storage tank for a long time (for more than a day in some cases), and this system is intended to address this issue. .

合弁１６にて混合され設定湯温になる。1 In the case of storing a large amount of hot water To store a large amount of hot water in the hot water storage tank 7, first close the second solenoid valve 26, open the first solenoid valve 27, and then turn on the operation switch (not shown) to start the circulation. Pump 17 operates. Then, the water in the cistern 1 flows through the lower outlet section 15, the first electromagnetic valve 27, the heat exchanger 14 of the heat source section 13, the hot water mixing valve 16, the circulation pump 17, and the hot water storage inlet section 9 in this order, and is poured into the hot water storage tank 7. Being bathed in hot water. At this time, the water undergoes heat exchange in the heat exchanger 14 and becomes hot water. The temperature of hot water stored in the hot water storage tank 7 depends on the temperature setting of the hot water mixing valve 16. That is, by operating the hot water mixing valve 16, the water flowing from the bypass circuit 18 and the hot water flowing from the heat exchanger 14 are mixed at the hot water mixing valve 16 to reach the set hot water temperature.
しかる後に、第１のレベルスイツチ１１まで
貯湯できればバーナ２４を停止し加熱を終了す
るとともに、循環ポンプ１７も停止する。 After that, if the hot water can be stored up to the first level switch 11, the burner 24 is stopped to complete heating, and the circulation pump 17 is also stopped.

一定湯温にて貯湯する方式であるので第２図お
よび第３図の特性ｂに示すように安定した湯温
を得ることができる。なお第３図においては
200、流量12／Ｍである。 If the hot water tap 20 is opened in this state, the hot water pump 19 will pump out a large amount of hot water. In this case, the hot water supply performance is such that hot water is stored at a constant temperature in the hot water storage tank 7, so that a stable hot water temperature can be obtained as shown in characteristic b in FIGS. 2 and 3. In addition, in Figure 3
200, flow rate 12/M.

で湯切れに対する欠点が解消されることにな
る。 Now, hypothetically, if we consider the drop into the bathtub, the capacity of the hot water pump 19 is generally 10~15/
M, and the fall is completed in a short time (approximately 10 to 12 minutes). The feature of the embodiment is that hot water can be stored even during hot water supply (circulation pump 17 can store hot water at 2.6~2.8/M at 60 ~
65 deg ), which eliminates the drawback of running out of hot water.
２ 少量貯湯の場合
多量貯湯の湯を使い果した場合および、少量
だけ貯湯する場合への対応であり、第２のレベ
ルスイツチ１２の制御により少量貯湯できるも
のである。2. Case of storing a small amount of hot water This is a case where the hot water stored in a large amount is used up or a case where only a small amount of hot water is stored.A small amount of hot water can be stored by controlling the second level switch 12.
少量貯湯の場合の動作としては多量貯湯の場
合と同様である。 The operation when storing a small amount of hot water is the same as when storing a large amount of hot water.
少量貯湯の条件設定としては40程度（落込
みを除く給湯負荷量）であり、高温湯（60〜
65deg）が冬期でも14〜15分で得られる（循環
量2.6〜2.8／Ｍとして）。 The conditions for storing a small amount of hot water are around 40 (hot water supply load excluding drops), and high temperature water (60~
65 deg ) can be obtained in 14 to 15 minutes even in winter (as a circulation rate of 2.6 to 2.8/M).
したがつて、落込みを除く給湯負荷に対して
は給湯中にも連続的に高温湯を貯湯できるので
湯切れがないものである。湯切れに対する一般

荷を示す。つまり、短時間に湯の使い果す給湯
パターンの場合は前述のように回復に時間を要
することが明らかである。 Therefore, hot water can be stored continuously even during hot water supply for hot water supply loads other than dips, so there is no shortage of hot water. Figure 4 shows the state of large and small hot water storage in the case of a general hot water supply pattern in response to running out of hot water, in comparison with more than 200 conventional hot water storage type hot water systems. In the figure, a indicates the present embodiment, b indicates the conventional one, and the shaded areas indicate various hot water supply loads. In other words, in the case of a hot water supply pattern in which hot water is used up in a short period of time, it is clear that recovery takes time as described above.
３ 循環加熱の場合
貯湯槽７の湯量としては少量貯湯か多量貯湯
のいずれかである。前記のように高温湯を貯湯

で以上に動作を示す。3. In the case of circulating heating The amount of hot water in the hot water storage tank 7 is either a small amount or a large amount. As mentioned above, hot water was stored, but for some reason it was stored for a long time (in some cases, 1 day).
This is when the water temperature drops after not being used (for more than a day).

磁弁２７は閉じている。 When a circulation switch (not shown) is manually turned on, the second solenoid valve 26 opens, the circulation pump 17 is activated, and the heat source section 13 is turned on.
At this time, hot water is fed at the temperature set by the hot water mixing valve 16. At this time, the first solenoid valve 27 is closed.

When the set water temperature of 6 is reached, the circulation pump 17,
The heat source section 13 and the second solenoid valve 26 are stopped.

の後、貯湯槽７に送り入れられることになる。 In this case, various temperatures of the remaining hot water in the hot water storage tank 7 are possible. Therefore, in the case of circulating heating, the remaining hot water reaches the temperature of the inlet water to the heat source section 13 and is sucked through the bypass circuit 18 to the hot water mixing valve 16. In other words,
One side of the remaining hot water is heated by the heat source section 13 and sent to the hot water mixing valve 16, and the other side is sent to the hot water mixing valve 16 without being heated via the bypass circuit 18. Here, the water is mixed to a preset temperature. Thereafter, it will be sent to the hot water storage tank 7.

This adds control using a mixing valve to temperature control at the heat source, providing highly accurate control.
