産業上の利用分野
本発明は、ガス、石油、電気等を熱源とし、浴
槽等への給湯、追焚を行う複合給湯機に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a composite water heater that uses gas, oil, electricity, or the like as a heat source and supplies hot water to a bathtub or the like and reheats the bathtub.
従来例の構成とその問題点
従来、この種の給湯、追焚システムは第１図に
示すように構成されている。Conventional configuration and its problems Conventionally, this type of hot water supply and reheating system has been configured as shown in FIG.
器具本体１内に強制通水型熱交換器２（以下、
熱交２とする）と自然循環型熱交換器３（以下、
熱交３とする）を設け熱交３の循環パイプ４を介
して浴槽５に接続してある。 A forced water flow type heat exchanger 2 (hereinafter referred to as
heat exchanger 2) and natural circulation heat exchanger 3 (hereinafter referred to as
A heat exchanger 3) is provided and connected to the bathtub 5 via a circulation pipe 4 of the heat exchanger 3.
熱交２の出湯口は温度検知器８を構成後、器具
外で分割（設置工事の時点で実施）され給湯栓
６、給湯栓７（浴槽５に臨むように構成する。）
を取付ける構成である。 After configuring the temperature sensor 8, the hot water outlet of the heat exchanger 2 is divided outside the appliance (performed at the time of installation work), and is divided into a hot water tap 6 and a hot water tap 7 (configured so as to face the bathtub 5).
This is the configuration for installing.
燃料は入口部９から供給され、熱交２、熱交３
に対応して設けられる加熱器１０、加熱器１１に

る。１４は設定器、１５は制御部である。設定器
１４は遠隔設置構成もある。 Fuel is supplied from the inlet 9, and the heat exchanger 2 and the heat exchanger 3
A heating operation is performed by a heater 10 and a heater 11 provided correspondingly. Further, each fuel supply system includes a combustion controller 12 and a fuel controller 13. 14 is a setting device, and 15 is a control section. The setting device 14 also has a remote installation configuration.

応じた湯温になるように温度検出器８でフイード
バツクされ加熱量を制御する。 When hot water is supplied by dropping into the bathtub 5 using the heat exchanger 2, when the hot water tap 7 is opened, fuel is supplied to the heater 10 by the combustion controller 12, and the hot water temperature is adjusted according to the setting device 14. Feedback is provided by a temperature detector 8 to control the amount of heating.
この時、給湯栓７は全開であり、最大流量とな
り給湯負荷も最大となる。従つて他の給湯栓６を
開栓しても、流量（温度は設定通り）が十分に得
られない。この原因として、複合給湯機は浴槽５
の横に設置されるため、給湯栓６（台所等に遠く
配管する場合が多い）の配管抵抗は給湯栓７より
当然大きくなり、流量配分にも自然に差が発生す
ることに起因する。従つて設置工事条件によつて
は全く流量（給湯）を得ることができないことも
あり、使用上の問題が多い。 At this time, the hot water supply faucet 7 is fully open, and the flow rate is at its maximum, and the hot water supply load is also at its maximum. Therefore, even if the other hot water taps 6 are opened, a sufficient flow rate (temperature as set) cannot be obtained. The cause of this is that the combined water heater
This is because the piping resistance of the hot water tap 6 (often piped far away, such as in the kitchen) is naturally greater than that of the hot water tap 7, which naturally causes a difference in flow rate distribution. Therefore, depending on the installation construction conditions, it may not be possible to obtain a flow rate (hot water supply) at all, which poses many problems in use.
追焚時は熱交２を長時間に渡つて関接加熱する
ため、給湯した場合、高温湯が出湯することもあ
る。 During reheating, the heat exchanger 2 is indirectly heated over a long period of time, so when hot water is supplied, hot water may come out.
発明の目的
本発明はこのような従来の欠点を除去するもの
で、多栓給湯での使い勝手の向上及び追焚時の給

ある。OBJECTS OF THE INVENTION The present invention is intended to eliminate such conventional drawbacks, and aims to improve usability in multiple tap hot water supply and to prevent after-boiling on the hot water supply side during reheating.

方を器具外の出湯回路へ導くものである。Structure of the Invention In order to achieve this object, the present invention divides a forced water flow type heat exchanger within the appliance main body to form divided parts, and connects one to the other heat exchanger (bathtub) through a hot water pouring circuit. The hot water is poured into a hot water exchanger (heat exchanger), and the other is led to a hot water supply circuit outside the appliance.
分割部は注湯回路、出湯回路への給湯配分及び
優先切換え構成を有し制御は設定器、制御部と温
度検知器で実行する。 The dividing section has a hot water supply distribution and priority switching configuration for a hot water pouring circuit and a hot water tapping circuit, and control is performed by a setting device, a control section, and a temperature sensor.
例ば注湯回路による落し込み給湯中に他の給湯
栓で使用する場合は設定器の選択によつて分割部
の配分比を制御するため、使用目的に対応し安
く、使い勝手を向上する。 For example, when using another hot water faucet during drop-in hot water supply by the hot water pouring circuit, the distribution ratio of the divided portions is controlled by selecting the setting device, so it is compatible with the purpose of use, is inexpensive, and improves usability.
又設置工事上、注湯回路側と出湯回路側の通水
抵抗が大きくなつた場合においても一度分割部の
配分比を固定設定することで容易に改善できる。 Furthermore, even if the water flow resistance on the hot water pouring circuit side and the hot water outlet circuit side becomes large during installation work, it can be easily improved by once setting the distribution ratio of the divided parts fixed.
優先切換えできることから追焚側による給湯側
の加熱作用（後沸き）もバイパスすることも可能
となり安全面での改善も得るものである。 Since priority switching is possible, it is also possible to bypass the heating action (post-heating) on the hot water supply side by the reheating side, which also improves safety.

る。 In the above configuration, when hot water is supplied to the hot water tap 24 while the heat exchanger 17 is dropping hot water into the bathtub 20 from the heat exchanger 18 (FIG. 3), in the conventional case, due to the difference in resistance, the hot water tap 24
However, with this configuration, the adjustment can be easily made by changing the position (angle) of the split rotor 22a of the split portion 22 using the setting device 34, By increasing the size, it is also possible to turn off the drop-in hot water supply. This effect can also solve problems during installation work.

前記した温度上昇を防ぐことができる。 Further, reheating using the heat exchanger 18 is as follows.
The heat exchanger 18 transfers the heat to the water in the water pipe 19 and performs a temperature raising action, and as the temperature rises, a circulation action occurs and the water in the bathtub 20 is successively heated. In this case, all of the heat generated by the heater 32 is not exchanged, and generally 70 to 75% is exchanged.
Other heat is released to the outside of the instrument body 16 or is retained within the instrument body 16 through convection, radiation, and the like. In this case, since the water remains in the heat exchanger 17 at room temperature, the temperature naturally increases until it absorbs this heat and maintains the heat balance, generally reaching 60 to 70°C. In particular, the more compact the instrument main body 16 is, the more conspicuous it becomes. However, in this configuration, the temperature detector 21 detects the state and rotates the divided rotor 22a to bypass the hot water to the pouring pipe 13.
It is possible to keep the water in the bathtub 20 by the heat exchanger 18, thereby preventing the above-mentioned temperature rise.
