常時の動作は従来例と全く同一になる。In this embodiment, a sub-controller 1 is added to the configuration of the conventional example.
4 and a selector 15 are added. Since the control system by the controller 9 is normally selected by the selector 15 at the normal time, the operation at the normal time is exactly the same as the conventional example.

る。However, for example, 200 exceeding the range of -20 ° C. to 110 ° C. which is normally detectable by the tapping temperature detector 6
If a signal corresponding to ° C. is issued, the abnormality controller 13 stops the operation of the heater 5 as a failure of the tapping temperature detector 6.

７の故障として、加熱器５の運転を停止する。The flow rate detector 7 outputs a pulse having a frequency corresponding to the flow rate as a flow rate signal. Exceeding the upper limit of 20 l / min which is normally detectable by the flow rate detector 24
Assuming that a signal corresponding to 1 / min is output, the abnormality controller 13 determines that the flow rate detector 7 has failed and stops the operation of the heater 5 in the same manner as when the tapping water temperature detector 6 fails.

モード等もある。However, in the case of the flow detector 7, when a failure occurs, the flow signal (pulse) is lost. In other words, there is a failure mode in which the flow rate of 0 l / min, which is usually possible, remains, and as a result, the heater 5 cannot be turned on even though the abnormality controller 13 does not operate.

できる。Since the sub-controller 14 drives the heater 5 irrespective of the signal from the detector, the sub-controller 14 heats the water even when the tapping water temperature detector 6, the flow rate detector 7 and the like are out of order as described above. Hot water can be supplied, and even when trouble occurs or when it takes time to procure repair parts, hot water can be applied to the bathtub as an emergency measure.

に対応できる。The tapping temperature detector 6 comprises a detecting section using a thermistor and a detecting circuit section for converting a change in the resistance value of the thermistor into a voltage value. In the conventional example, in the case of a failure of the detection unit, the heater 5 can be operated by connecting a dummy resistor corresponding to the resistance value of the thermistor on which the heater 5 operates. It can respond to the failure of the detection circuit part of the detector 6 and the failure of the detector which cannot input the dummy signal easily because the detection signal is a pulse like the flow detector 7 without using any repair parts. Can respond.

いる。As for safety, if the selector 15 is switched to the sub-controller 14 without flowing water into the water circuit 3, the sub-controller 14 turns on the heater 5 without using the signal of the flow rate detector 7. For this reason, it is conceivable that the heat exchanger 4 may be fired empty. In such a case, the heat exchange abnormality detector 11 and the protector 1 may be used.
The minimum safety is secured by shutting off the drive signal of the sub-controller 14 and turning off the heater 5 by 2.

The same components as those of the conventional example are denoted by the same reference numerals and the same names, and the description of the operation is omitted. Also in this embodiment, a sub controller 14 and a selector 15 are added to the configuration of the conventional example. Since the control system by the controller 9 is normally selected by the selector 15 at the normal time, the operation at the normal time is exactly the same as the conventional example.

Preventing. Further, the calorific value of the heater 5 is changed according to the flow rate so that the inside of the heat exchanger 4 does not boil.
