Abstract

PURPOSE:To provide a hot water supply system combined with a hot water supplier of an energy-sparing, low-input and tap-control type and a large capacity hot water storage tank by forming a circulating path by a hot water storage tank, a threeway valve, a heat source and a three-way valve, connecting both three-way valves to each other, and connecting the three-way valve at the rear stream of the heat source to a hot water foucet. CONSTITUTION:When a circulating pump 9 is operated, the burner 18 of a heat source 7 is turned ON by a signal from a flow quantity, hot water temperature control thermistor 15, and heated by a heat exchanger 8. High-temperature hot water flows into a hot water tank 1 through a hot water supply return pipe 12, a flow quantity control orifice 13, and the hot water within the hot water tank 1 flows out from an outlet port 6 and is circulated. When hot water of a predetermined temperature is stored, the burner 18 is stopped by the operation of the thermistor 15. Furthermore when the hot water supply faucet 14 is opened, a pump 9 is driven by a detection signal of flow quantity switch 20, the burner 18 is ignited by a signal of the thermistor 15 a circuit between the three-way valves 11 and 11' is closed, and hot water flows out directly from a heating source 7 to a hot water faucet 14. By this arrangement, energy-saving, and instantaneous type and hot water storage type combined functions are provided by a pump.

二極化しているのが現実である。If the instant type is equipped with a large input capacity type, it can handle the hot water supply load and provide instant hot water supply. In addition, even if the hot water storage type has a low input capacity, if hot water of about 2,507° C. is stored at 80 to 85 degrees Celsius, high-temperature hot water can be dispensed even when the user calls. (The hot water supply curve in Figure 3 shows the usage range of instant hot water type and hot water storage type.) The reality is that each type has its own characteristics and is polarized.

次に貯湯式給湯機および瞬間式給湯機における具体的な
欠点を示す。Next, specific drawbacks of hot water storage type water heaters and instantaneous type water heaters will be shown.

必要となる。Disadvantages of hot water storage type water heaters 1: The amount of hot water stored is large, and it requires a long boiling time especially when the input is low, and even if the hot water is used up in a short time, even if you want a little more hot water, you can still boil a large amount. It requires a long boiling time.

することになる。Disadvantages of Instant Water Heaters 1 In recent years, hot water supply methods have increased in the form of hot water being poured into baths, and hot water supply capacity has tended to increase. The capacity of the equipment is 13 to 18 (26,000 to 36 o in imp soto conversion)
OoKCal/h). Therefore, as the heat exchanger becomes larger and has a larger heat capacity, "startup heating loss" increases.

２　給湯条件の異なる場合の同時使用においては給湯能
力の大きい条件に依存し、使い勝手が悪いものである。2. Simultaneous use under different hot water supply conditions is dependent on the condition of large hot water supply capacity, making it inconvenient to use.

The present invention takes advantage of the features of the instantaneous type and hot water storage type, and provides a 7L hot water supply system that solves the drawbacks of both. The next point is this.

１　熱源の能力としては低インプット能力とし瞬間式給
湯機とする。従って、熱交換器容量が小さくて済み、立
上りの加熱ロスを少なくすることができる。1 The heat source capacity will be an instant water heater with low input capacity. Therefore, the capacity of the heat exchanger can be small, and the heating loss during startup can be reduced.

２　大容量の貯湯槽と組合せて貯湯式給湯機とすること
で同時使用が可能である。2. Simultaneous use is possible by combining it with a large-capacity hot water storage tank to create a hot water storage type water heater.

When hot water has already reached the set temperature at the time of dispensing and reheating (reheating) is not required, the heat is passed through a separate channel without passing through the heat source, thereby reducing the amount of heat radiated and improving economic efficiency and usability.

以上のように熱源部と貯湯槽を七ノ（レートにししかも

On the inlet side of the hot water storage tank 1, a pump 9 for both hot water supply and circulation, which is directly connected to the outlet part 6 of the hot water storage tank 1, and a three-way switching part A11 are connected by a hot water supply outgoing pipe 1o. In addition, the outlet side of the heat exchanger 8 is a three-way switching section B1.
1', and communicates with the hot water supply return pipe 12. Further, the other end of the three-way switching section A11 and the three-way switching section B11' are connected.

This is the flow rate switch B that operates the flow rate switch B.

以上の構成において、１多量貯湯の場合、２瞬間式の場
合について動作２作用面について述べる。In the above configuration, operation 2 aspects will be described for 1 case of large quantity hot water storage and 2 cases of instantaneous type.

湯入口部６より送り込まれる。1. In the case of large quantity hot water storage, when the hot water storage tank 1 is filled with water and an operation switch (not shown) is turned on, the hot water supply/circulation pump 9 is activated. Then, the burner 18 of the heat source section 7 is turned on by the signal from the flow rate and hot water temperature control thermistor 16, and the heat exchanger 8 is turned on.
is heated. The heated hot water is returned to the hot water supply pipe12. It passes through the flow control orifice section 13 and is sent from the lower bulk hot water storage inlet section 6 in the hot water storage tank 1 .

この後に湯温制御サーミスタ１６の設定湯温に達すれば
バーナ１８を停止し、加熱を終了する。After this, when the hot water temperature reaches the set temperature of the hot water temperature control thermistor 16, the burner 18 is stopped and heating is completed.

この状態で給湯栓１３を開栓すれば高温湯は熱交換器８

にて多量の高温湯を送り出すことになる。If you open the hot water tap 13 in this state, the hot water will flow to the heat exchanger 8.
Directly from three-way switching section A11 to three-way switching section B without passing through
11', and the hot water supply/circulation pump 9 sends out a large amount of hot water at full capacity.

費を節減でき経済性に富むと同時に多量給湯による使い
勝手も優れたものである。多量貯湯の場合は出湯時の均
一湯温か得られることが絶対条件となる。In this case, the high-temperature hot water has relatively high flow resistance and does not pass through the heat exchanger 8, which has a heat transfer area, so it is possible to fully demonstrate its capacity with a small hot water supply/circulation pump, and further heat exchange is possible. Since the amount of heat radiated from the device is small, power consumption and fuel costs can be reduced, making it highly economical. At the same time, it is easy to use as it can supply a large amount of hot water. In the case of storing a large amount of hot water, it is an absolute requirement that a uniform hot water temperature be obtained when hot water is tapped.

しく、かつ、貯湯槽の最下部より送り込むことで貯湯槽

。In order to satisfy this condition, experimental evidence suggests that it is desirable to keep the circulating flow rate into the hot water storage tank low and to use high-temperature hot water, and to stabilize the capacity of the hot water storage tank by feeding it from the bottom of the tank. It was found that a large proportion of hot water temperature (generally expressed as effective stable hot water output) could be obtained.

オリ□）アイス部を設は循環量を制御し・　　１＼。Therefore, since it is desirable to have a high flow rate when supplying hot water, one pump is used for both hot water supply and circulation.

ているものである。It is something that

これは、貯湯槽内の下部より高温湯を対流スピードの遅
い条件にて沸き上げることにより、第４図に示すように
貯湯槽内の温度分布が少なくなり、第５図のように出湯
時の湯温安定が図れるものである。This is because by boiling high-temperature water from the lower part of the tank at a slow convection speed, the temperature distribution inside the tank is reduced as shown in Figure 4, and the temperature distribution at the time of hot water dispensing is reduced as shown in Figure 5. This allows for stable water temperature.

高温湯を低流速にて送り込む根拠を次に述べる。The rationale for sending high-temperature water at a low flow rate is explained below.

１　高流速にて送り込むと入口部から出口部向けての偏
向流が生じ易くなり、温度分布が悪くなる。従って、出
湯時の湯温安定性を欠くものとなる。1 When feeding at a high flow rate, a deflected flow tends to occur from the inlet toward the outlet, resulting in poor temperature distribution. Therefore, the hot water temperature stability during tapping is lacking.

２　高温湯が貯湯できた後に出湯させた場合に当然、給
水口より低温水が流入する。この際、追焚きする時に、
貯湯槽上部の高温湯と、下部の低温水を攪拌してしまう
ことになり不都合が生じるものとなる。2. When hot water is turned on after high temperature hot water has been stored, low temperature water will naturally flow in from the water inlet. At this time, when rekindling the fire,
The high temperature water in the upper part of the hot water storage tank and the low temperature water in the lower part are agitated, which causes inconvenience.

以上の点を考え条件設定するものとなる。また、本実施
例ではオリフィス制御しているが、ポンプの極数変換し
制御する方法も考えられるものである。Conditions should be set considering the above points. Further, although orifice control is used in this embodiment, a method of controlling the pump by changing the number of poles may also be considered.

２瞬間式としての場合 給湯を多量必要としない場合、例えば、入浴しない日お
よび真夏時などは、瞬間式給湯器のしか１゜ も低能力で十分である。従って、この場合においては瞬
間式給湯機として使用する方法をとる。In the case of a two-instant water heater, when a large amount of hot water is not required, for example, on days when bathing is not done or in the middle of summer, an instantaneous water heater with a capacity as low as 1° is sufficient. Therefore, in this case, the method is to use it as an instant water heater.

り高温湯が得られることになる。Therefore, when the operation switch is turned on and the hot water tap 14 is opened, the hot water supply/circulation pump 9 is started by detection by the flow rate switch A20. Then, the water temperature of the hot water supply pipe 1o is detected,
The burner 18 is ignited by a signal from the hot water temperature control thermistor 15. After a while in this state, high-temperature hot water will be available from the tap 14.

式給湯機としての機能として対応できる。In this case, the circuit of the three-way switching section A11 and the three-way switching section B11' is in a "closed" state, and the water sent by the hot water supply/circulation pump 9 is transferred to the three-way switching section A11. Heat exchanger 8, three-way switching section B
It passes through the circuit 11', and at this time it functions as an instantaneous water heater. In addition, if you need to supply hot water after the entire stored hot water capacity (for example, 25 ol) has been used up for some reason, or if you want to reheat (reheat) the hot water in the hot water tank 1, you can use an instant hot water heater. It can be used as a function.

以上のことから、シーズンおよび給湯負荷に対応できる
ものであり、例えば次のようである。From the above, it can be adapted to the season and hot water supply load, for example as follows.

１　冬期において風呂への落込みを含めた給湯（給湯負
荷大）の場合は貯湯式機能とする。1. In winter, when hot water is supplied to the bath including water supply (large hot water supply load), the hot water storage function is used.

（例えば８５℃−２ｔｓｏｌ　） まだ、２５０４１！を使い果しもう少し高温湯が欲しい
場合（給湯負荷小）は追焚きするか、必要量が少なけれ
ば瞬間式として給湯する。(For example, 85℃-2tsol) Still 25041! If you run out of water and want a little more hot water (the hot water supply load is small), you can heat it up again, or if the amount required is small, you can use an instant hot water system.

２　夏期においては、ジャワ主体の場合は低温の貯湯機
能とする。（例えば５０℃−２５０１）また、その他の
給湯時は瞬間式として対応する。2. In the summer, if the water is mainly Java, it will have a low-temperature hot water storage function. (For example, 50°C-2501) In addition, other types of hot water supply can be handled as instantaneous type.

まり、本給湯システムにおいて熱源部と貯湯槽をセパレ
ートしているのはこのためでもある。The system shown in FIG. 2 is designed to accommodate only kitchen-based hot water supply, and is a system in which only the heat source is separated from the hot water system shown in FIG. In other words, this is also the reason why the heat source and hot water storage tank are separated in this hot water supply system.

本発明のものは低インプ・イ、ト能力の先止式瞬間給湯
機とセパレートされた多量貯湯の貯湯槽を組Ｉ・１ 合せることで瞬間式と貯湯式の両機能を満足させる給湯
システム、とすることにより次の効果が得られる。The present invention is a hot water supply system that satisfies both the functions of an instantaneous type and a hot water storage type by combining a low-impact capacity pre-stop type instantaneous hot water heater and a separate large-capacity hot water storage tank. By doing so, the following effects can be obtained.

１　貯湯式と瞬間式を兼ねることにより各種の給湯負荷
への対応ができ使い勝手が向上することになる。1. By using both a hot water storage type and an instantaneous type, it can handle various types of hot water supply loads and improve usability.

２　低インプット能力なので熱交換容量が少なくて済み

３　ジスターンを有する貯湯槽とすることで水圧の影響

６　ひとつのポンプとオリフィス制御により、瞬間用と
貯湯用の三機能を兼ねることで低コストな給湯システみ

When a large amount of high-temperature hot water is dispensed, a configuration is adopted that does not allow the hot water to pass through the heat exchanger, so the influence of flow path resistance is small and there is little heat radiation loss from the high-temperature hot water. Therefore, there is a degree of freedom in selecting the pump and it is highly economical.
