摘要： PROBLEM TO BE SOLVED: To provide the technology capable of immediately detecting the failure in combustion at a part of burners, and stopping or controlling the combustion. SOLUTION: A gas is blown out from a nozzle 15 in accompany with the start of operation, but as an opening area of a suction port 20 is small, the sucking performance is impaired and the required air can not be sufficiently sucked. As a result, a primary air ratio of a mixture gas in the burner 2 is small, and the combustion can not be completed in an inner barrel. Under this situation, a length of the flame 5b is elongated, its tip is brought into contact with a lower end of a heat exchanger 3, and a flame current value is increased. The flame current value information of a flame current detecting circuit 12 is taken in a flame current monitoring means 6, and a combustion state is determined in a determining part 8. The information is supplied to an instruction part 9 at a time when the flame current value is over a threshold value Ith, and the instruction part 9 gives the instruction for disconnection to a solenoid valve 13.

摘要： PROBLEM TO BE SOLVED: To diagnose easily and surely the cause of a trouble such as lowering of the temperature of hot water which occurs in a gas appliance. SOLUTION: A water heater 2 is provided with a control device 4, which controls a gas burner 14 and others so that hot water of an inputted desired temperature may be supplied. Moreover, the control device 4 is connected with a storage device, which stores the content and the time of a bad working condition when it occurs in an operation and from which the content of storage can be read out as occasion demands. On the occasion of repairing the water heater being cut of order, the content of storage is read out to know the situation of occurrence of the bad working condition. When characteristic points making it possible to regard the bad working condition as caused by a disturbance are seen in this condition, it can be judged to be caused by a trouble outside a gas appliance, such as lowering of water pressure, for instance. According to this constitution, the cause of the trouble being hard to explicate and little reproducible can be found out with ease and the repair of the gas appliance can be conducted easily and simply.

摘要： PROBLEM TO BE SOLVED: To specify the abnormal cause of a second heating operation by specifying either the closure of a circulation path or the fault of a circulating pump, etc., based on the detection result of a pressure sensor, a bath thermistor and a water flow switch. SOLUTION: A CPU 9, when hot water pouring being started, measures a being started, measures a time t1 until hot water temperature detected by the bath thermistor 7 starts to change after the pressure sensor 5 detects hot water pressure. When difference |t1 -t0 | between the time t1 and a time t0 measured when a hot water supplier is installed and stored in an EEPROH 10 is within an allowable time range Δt, the difference p1 of pressure detected by the pressure sensor 5 in the driving/non-driving state of the circulating pump is measured in a state in which a bathtub is filled with hot water to a prescribed level. It is judged whether or not the difference between pressure difference p0 when the hot water supplier is installed is within tolerance, and when it is, a time until a bath water flow switch 8 is turned on after the circulating pump is driven is measured, and it is judged whether or not it is within the tolerance. The closure of the circulation path and the fault of the circulating pump, etc., in each step are displayed on a display part 12.

摘要： PURPOSE: To realize a failure diagnosis requiring no modification of an apparatus nor measurements at a plurality of measuring points by determining the failure state and operating state based on the measurements of current flowing into the apparatus. CONSTITUTION: A computer 8 is brought into operating state and the power plug of a hot water supply is inserted into a commercial power supply socket through a current sensor 7 thus operating the ho water supply. The hot water supply is set normally and the current is detected by means of the sensor 7 and fed to a CPU 9 through an A/D converter 10. The CPU 9 determines the failure mode or the operating state based on the current value while grasping the sequential operation of an apparatus. When a failure mode is specified, components for which a failure is apprehended under that failure mode are specified and displayed 11. With such arrangement, manual measurements are not required at individual measuring points thus realizing failure diagnosis requiring no modification of apparatus nor measurements at a plurality of points.
