本発明はたとえば深夜電力温水器と、その他の
貯湯式温水器を組合せた給湯装置の沸き上げ温度
制御に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to boiling temperature control for a water heater that combines, for example, a late-night electric water heater and other hot water storage type water heaters.
従来の深夜電力温水器を使つた給湯装置は第３
図に示すように、深夜電力通電時間帯にヒータａ
に通電して、サーモスタツトｂにより温水温度が
80℃程度に沸き上がると通電停止するようになつ
たものが多い。又、一般に貯湯容量は300〜460
のものが多く使用されている。このように、高
温の湯を多量に保温すると、貯湯槽からの放熱ロ
スは見逃すことのできない大きなものとなる。特
に深夜電力を利用する場合、夜間に昇温した湯
は、一般に夕方に給湯利用が集中するため朝、昼
の長時間高温の湯を保温することになる。そこで
設定湯温を下げれば周囲気温との温度差が小さく

力温水器では高温の湯を多量にしかも長時間保温
しなければならないため、放熱ロスが大きかつ
た。 The conventional water heater that uses late-night electric water heaters is the third
As shown in the figure, heater a is
energizes and the hot water temperature is set by thermostat b.
Many of them now turn off the electricity when the temperature reaches around 80 degrees Celsius. In addition, generally the hot water storage capacity is 300 to 460
are often used. In this way, when a large amount of hot water is kept warm, the heat loss from the hot water storage tank becomes large and cannot be overlooked. Particularly when late-night electricity is used, the hot water heated during the night must be kept hot for a long time in the morning and afternoon, since hot water usage is generally concentrated in the evening. Therefore, lowering the set hot water temperature will reduce the temperature difference with the ambient temperature and reduce heat loss, but this will reduce the amount of heat retained, which may lead to a shortage of hot water when the hot water supply load is high. In this way, conventional late-night electric water heaters had to keep large amounts of hot water warm for long periods of time, resulting in large heat loss.
本発明は、上記従来の欠点を除去するもので、
貯湯槽からの放熱ロスを小さくするとともに、湯
量不足の発生しない給湯を可能にすることを目的
とする。 The present invention eliminates the above-mentioned conventional drawbacks,
The purpose is to reduce heat loss from a hot water storage tank and to supply hot water without causing a shortage of hot water.
この目的を達成するために本発明は、残湯量検

湯温を変更する制御装置を設けたものである。 In order to achieve this object, the present invention connects the hot water outlet of a late-night electric water heater with a built-in residual hot water amount detection device to the water inlet of a hot water storage type water heater that can change the set boiling water temperature, and A control device is provided for changing the boiling water temperature setting of the hot water storage type water heater in accordance with the remaining hot water amount detection signal of the hot water amount detection device.
この構成で、前記貯湯式温水器の沸き上げ設定
湯温を前記深夜電力温水器の残湯量に反比例する
ように変更することによつて、深夜電力温水器の
残湯量が少なくなり保有熱量が減つても、貯湯式
温水器側は設定湯温が上がり保有熱量は増すた

水器の保有熱量を減らすことができ貯湯量を減少
あるいは設定温を低下できるため、放熱ロスは減
少する。又、貯湯式温水器の設定温度も給湯が開
始するまで高温にならないため、放熱ロスは少な
い。 With this configuration, by changing the boiling water temperature setting of the hot water storage type water heater so as to be inversely proportional to the amount of remaining hot water in the late-night electric water heater, the amount of remaining hot water in the late-night electric water heater decreases and the amount of heat it retains decreases. However, the hot water storage type water heater side raises the set water temperature and retains more heat, so there is no longer a shortage of hot water. Therefore, it is possible to reduce the amount of heat held by the late-night power water heater, thereby reducing the amount of hot water stored or lowering the set temperature, thereby reducing heat radiation loss. Furthermore, the set temperature of the hot water storage type water heater does not reach a high temperature until hot water starts being supplied, so there is little heat radiation loss.

する給湯配管。 In FIG. 1, 1 is a late-night electric water heater that incorporates a late-night electric heater 2, a hot water temperature setting thermometer 3, and a remaining hot water amount detection device 4; 5 is a hot water storage type water heater that has a built-in heat exchanger 6 and a hot water temperature detector 7 8 is a tap water supply pipe connected to the lower end of the late-night electric water heater 1, and 9 connects the hot water outlet 10 at the upper end of the late-night electric water heater 1 to the water inlet 11 at the lower end of the hot water storage type water heater 5. The remaining hot water amount detection device 4 has four thermistors 12 arranged in a row in the height direction of the late-night electric water heater 1 so that each thermistor detects the tap water temperature (for example, a temperature below 30°C) or the hot water temperature. 13 is a combustion device that sends combustion air to the heat exchanger 6 and the exhaust stack 14; 15 is a combustion device 13 that sends combustion air to the heat exchanger 6 and the exhaust stack 14; of
A control device that performs ON/OFF control, and 16 a hot water supply pipe that connects a hot water supply port 17 and a faucet 18 at the upper end of the hot water storage type water heater 5.
次に制御装置１５の動作を第２図より説明す
る。Ｖは残湯量検知信号から求めた深夜電力温水
器１の残湯量、Ｔは貯湯式温水器５の設定湯温で
ある。深夜電力温水器１の沸き上げ直後（設定湯
温60℃とする）は全て湯であるので残湯量はV1
この時の設定湯温をt1（60℃とする）とする。給
湯が始まると深夜電力温水器１の下部より水道水
が入つてくるため湯は上部へ押し上げられる。こ
の時残湯量V2となれば設定湯温をt2（例えば70
℃）に上げる。さらに給湯が進み、残湯量が最低
ラインV3になると、設定湯温をt3（例えば85℃）
に上げる。このように深夜電力温水器１の残湯量
Ｖに反比例するよう貯湯式給湯器の設定湯温Ｔを
定める。 Next, the operation of the control device 15 will be explained with reference to FIG. V is the amount of remaining hot water in the late-night electric water heater 1 determined from the remaining hot water amount detection signal, and T is the set hot water temperature of the hot water storage type water heater 5. Immediately after the late-night electric water heater 1 starts boiling (set water temperature is 60℃), all the water is hot water, so the remaining amount of hot water is V 1
The set water temperature at this time is t 1 (60℃). When hot water supply starts, tap water enters from the bottom of the late-night electric water heater 1, and the hot water is pushed up to the top. At this time, if the remaining hot water amount is V 2 , change the set hot water temperature to t 2 (for example, 70
℃). When the hot water supply progresses further and the remaining hot water amount reaches the minimum line V 3 , change the set hot water temperature to t 3 (e.g. 85℃)
Raise it to In this way, the set hot water temperature T of the hot water storage type water heater is determined so as to be inversely proportional to the amount of hot water remaining V in the late-night electric water heater 1.
このように、貯湯式温水器の沸き上げ設定湯温
を深夜電力温水器の残湯量に反比例するように変
更することによつて、深夜電力温水器の残湯量が
少なくなり保有熱量が減つても貯湯式温水器側は
設定湯温が上がり保有熱量は増すため、湯量不足
の発生はなくなる。又、深夜電力温水器の保有熱
量を減らすことができるため、設定湯温を下げ放
熱ロスを減少できる。さらに、貯湯式温水器の設
定湯温も給湯量が増すまで低温で保持されるた
め、放熱ロスは少ない。 In this way, by changing the boiling water temperature setting of the storage type water heater so that it is inversely proportional to the amount of remaining hot water in the late-night electric water heater, even if the amount of remaining hot water in the late-night electric water heater decreases and the amount of heat it retains decreases. On the hot water storage type water heater side, the set water temperature rises and the amount of heat it holds increases, so there is no longer a shortage of hot water. Furthermore, since the amount of heat retained by the late-night electric water heater can be reduced, the set water temperature can be lowered and heat radiation loss can be reduced. Furthermore, the set water temperature of the hot water storage type water heater is maintained at a low temperature until the amount of hot water supplied increases, so there is little heat loss.

(1) Lower the set water temperature of the late-night electric water heater, or
Alternatively, the amount of hot water stored in late-night electric water heaters can be reduced, reducing heat radiation loss.
(2) 貯湯式温水器の設定湯温が給湯の少ない時間
帯（朝、昼）は低くできるため、放熱ロスが少
ない。(2) The hot water temperature setting of the hot water storage type water heater can be lowered during times when hot water supply is low (morning and afternoon), so there is less heat loss.
(3) 深夜電力温水器の保有熱量が減少した時に、
貯湯式湯水器の保有熱量が増大するため、給湯
の熱量不足を解消できる。(3) When the amount of heat retained by the late-night electric water heater decreases,
