。The main solenoid valve 11, the hot water supply solenoid valve 12, and the proportional control valve 13 are opened to keep the fuel ignited. (The ignition holding means is not particularly shown) The hot water supply heat exchanger 1 is heated by the combustion of the hot water supply burner 14, and the heated hot water is passed through the hot water supply control valve 24, the check valve 29, and the hot water circulation path. Hot water is automatically supplied to the bathtub 4 from the hot water spout 2b through the rear-end heat exchanger 2.

安定に制御して、浴槽４へ自動給湯する。The control circuit 27 detects the hot water supply temperature using both the hot water supply thermistor 18 and the rear misc 20, and controls the hot water supply temperature to the temperature set by the bathtub hot water temperature setting device (not shown) of the remote control 28. The proportional control valve 13 is operated using the calculated output to control the combustion amount of the hot water supply burner 14 to stably control the temperature of hot water and automatically supply hot water to the bathtub 4.

るからである。In this way, the combustion amount of the hot water supply burner 14 is controlled by the signal from the rear collision thermistor 20. Even if the hot water supply thermistor 18 and the rear collision thermistor 20 have the same specifications, the hot water supply characteristics may differ due to component variations. The set temperature of the thermistor 18 may become high or low, and the desired bath boiling temperature set with the bathtub water temperature setting device may not be reached. This is because by controlling the combustion amount of the burner 14, the bath can be reliably heated to the desired bath temperature set by the bath water temperature setting device.
こうすることによって、所期の風呂沸き上げ温度に追突
運転をせずに自動給湯運転のみで完了することが出来る
。By doing this, it is possible to complete the automatic hot water supply operation only without having to perform a rear-end operation to reach the desired bath boiling temperature.

を閉弁して自動給湯を停止することが出来る。The amount of hot water supplied to the bathtub 4 uses a water amount sensor that counts the amount of water supplied to the water supply detection element 17, so the amount of ignition/extinguishing water is detected, and the amount of automatic hot water supply is calculated and measured by the control circuit 27 during automatic hot water supply operation. automatically closes the hot water supply control valve 24.
Automatic hot water supply can be stopped by closing the valve.
