る。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 shows a water heater of the present invention. Hot water from the instantaneous water supply machine 1 is supplied through a hot water supply pipe 3 to a water outlet composed of a hot water supply port 2 and a drain port 7. The opening and closing of the hot water supply valve 6 is controlled by a hot water supply control section 7, and hot water from the hot water supply pipe 3 is supplied to the hot water supply port 2. The opening and closing of the drain valve 8 is controlled by the hot water supply control section 7, and hot water from the hot water supply pipe 3 is supplied to the drain port 9. Temperature detection unit 10 is provided in the water outlet and detects the temperature of hot water at the water outlet.
上記構成において、給湯温度制定部４で給湯口
２からの出湯温度を設定し、給湯を要求すると、
給湯制御部７は、瞬間給湯機１に設定温度の出湯
をさせるとともに、温度検出部１０で出水口の水
温を検出する。ここで出水口での水温の温度差が
設定温度の許容範囲内の場合は、給湯弁６を開き
給湯口２に湯水を供給する。出水口での水温の温
度差が設定温度の許容範囲外の場合は、排水弁８
を開き排水口９に湯水を供給する。よつて給湯開
始時に、給湯管３内の死水の温度が設定温度と許
容範囲内の温度差でない場合は、排水口９より排
出し、死水が排水し終つて出水口の水温が設定温
度の許容範囲内に入ると排水弁８を閉じ、給湯弁
６を開くことで、給湯開始時から給湯口２に設定
温度の湯水を供給する。 In the above configuration, when the hot water temperature setting unit 4 sets the temperature of hot water coming out from the hot water supply port 2 and requests hot water supply,
The hot water supply control section 7 causes the instantaneous water heater 1 to dispense hot water at a set temperature, and the temperature detection section 10 detects the water temperature at the water outlet. Here, if the difference in water temperature at the water outlet is within the allowable range of the set temperature, the hot water supply valve 6 is opened to supply hot water to the hot water supply port 2. If the water temperature difference at the water outlet is outside the allowable range of the set temperature, drain valve 8
Open and supply hot water to the drain port 9. Therefore, at the start of hot water supply, if the temperature of the dead water in the hot water supply pipe 3 is not within the set temperature and the allowable temperature range, it will be discharged from the drain port 9, and after the dead water has been drained, the water temperature at the water outlet will be within the allowable set temperature. Once within the range, the drain valve 8 is closed and the hot water supply valve 6 is opened to supply hot water at the set temperature to the hot water supply port 2 from the start of hot water supply.
上述から明らかなように、給湯口２と排水口９
が一対になつた出水口と温度検出部１０を設ける
ことにより、給湯管内の死水が、設定温度の許容
温度差内に入つていない場合、給湯口から温度の
異つた湯水が流出することが防げる。 As is clear from the above, the hot water supply port 2 and the drain port 9
By providing a pair of water outlet and temperature detection unit 10, if the dead water in the hot water pipe is not within the allowable temperature difference of the set temperature, hot water with a different temperature will not flow out from the hot water outlet. It can be prevented.
発明の効果
以上のように本発明によれば、出水口に給湯口
と排水口を設け、出水口の近傍に温度検出部を設
けることにより、設定温度の許容温度差の範囲外
の時に排水口より排水できるので、給湯口より流
出する死水の不快感が抑えられ、シヤワーのよう
な所では大きな効果がある。また出湯温度より死
水の温度が高い場合でも給湯口より高温水のでる
のを防止できる。Effects of the Invention As described above, according to the present invention, by providing a hot water supply port and a drain port at the water outlet, and providing a temperature detection section near the water outlet, the drain outlet Since it can drain more water, the discomfort caused by dead water flowing out from the hot water outlet is suppressed, which is very effective in places like showers. Furthermore, even if the temperature of the dead water is higher than the hot water temperature, hot water can be prevented from coming out from the hot water supply opening.
さらに出湯要求時にだけ温度検出動作と給湯
弁、排水弁の動作を行ない死水の排出動作を行う
のでエネルギーロスが小さくてすむものである。 Furthermore, since the temperature detection operation and the operation of the hot water supply valve and drain valve are performed to discharge dead water only when hot water is requested, energy loss can be reduced.
