摘要： PURPOSE:To eliminate the overflow of hot-water from a bathtub even when faulty detections have been generated continuously, by a method wherein a pressure sensor is provided on one of a forwarding pipeline and a returning pipeline, which constitute an additional heating circulation passageway, and airpurge and water pressure detection are repeated until a predetermined value is detected immediately after the air purge while a means, which,stops the fall-in of hot-water supply regardless of the detected value of water pressure when the air purges are effected predetermined times, is provided in the title device. CONSTITUTION:A return pipe 9 is used as a water pressure detection exclusive pipe and effects the sampling of a water pressure. When the fall-in of hot-water supply is progressed and a pressure sensor 11 has detected a predetermined value, a three-way valve 16 is switched and air in the returning pipe 9 is purged. When the three-way valve 16 is switched after the air purge, the water pressure is read again and the predetermined value is detected, it is decided that a set water level L is achieved and the fall-in supply is finished. When the predetermined value has not been detected, it is decided that air is interposed in the return pipe 9 and the faulty detection of the pressure sensor 11 has been generated, then, the fall-in of supply is returned to the supply through a forwarding pipe 8. The number of times of this repetition is detected and the fall-in of supply is finished when the repetition is effected for predetermined times.

摘要： PURPOSE:To improve the safety in regard to the oxygen defficiency and failure to shut off a hot water tap by forcing a suspension of burning and interrupting the counting action of a timer in case where an abnormal condition is detected by a water flow sensor. CONSTITUTION:Detection signals from a flow rate sensor 3, a thermistor 4 and a rotation sensor 9 are inputted to a controller 10. When a water flow is detected upon opening a hot water tap 5, a timer is set, and, if there is no abnormality from the sensors, a gas valve 7 is opened and a fan 8 is operated to start the burning at a gas burner 6. If the timer counts up, the gas valve is forcibly shut off and the 8 stopped to ensure the safety. If an abnormality is detected by any sensors, the burning is suspended to assume a burning holding mode. If the normal condition is regained under such a condition, the timer is not reset but resumes the counting action from the interrupted point. As a result, the burning time does not exceed the time period set by the timer even if an abnormality should occur.

摘要： PURPOSE:To make it possible to automatically shift to other control sequence when a fault in a circulating water channel system by providing timer means in which a measuring time is cleared by a signal from comparison means, and discrimination means for outputting a signal for stopping a hot water supplying sequence by a time-up signal from the timer means. CONSTITUTION:When a water channel changeover valve 20, a circulating pump 24 and the like of a circulating water channel system are in fault, water stored in a hopper 30 cannot be introduced into a bathtub 14. Therefore, the water level in the hopper is raised and a water quantity adjustor 34 acts to stop the water supply to the hopper 30. In accordance therewith, a timer setting signal is outputted from a comparison means 46, and a predetermined measuring time is set at a timer means 48. As long as a time clearing signal is not afforded from a comparison means 46 within the measured time, the timer means 48 outputs a time-up signal and outputs a signal after the lapse of the set time. A discrimination means 52 responds to the time-up signal and outputs a signal for stopping the hot water supply sequence and to shift the hot water supplier to other control sequence.

摘要： PURPOSE:To prevent mutual interference to occur when regulating a secondary pressure of gas and to regulate the same simply by a method wherein the title combustion device is provided with a means for setting the maximum and minimum voltages corresponding to a secondary pressure, and another means for operating an output voltage from set maximum and minimum voltages. CONSTITUTION:Voltages, corresponding to a regulated maximum secondary pressure and minimum secondary pressure, are stored in a gas amount operator 1 while the gas amount operator 1 operates based on the voltages corresponding to the regulated maximum secondary pressure and minimum secondary pressure and outputs a voltage signal corresponding to the necessary amount of gas from a voltage signal outputting terminal 3. The regulation of the maximum secondary pressure is effected by a method wherein a switch 6 for setting the maximum secondary pressure is turned on to output the voltage signal of the maximum secondary pressure from a voltage signal outputting terminal 3 and a maximum secondary pressure regulating resistor 8 is operated to regulate the maximum secondary pressure outputted from the signal outputting terminal 3. The regulation of the minimum secondary pressure may also be effected by the turning-on of a minimum secondary pressure setting switch 7 and the operation of a minimum secondary pressure regulating resistor 9 in the same manner.
