The auxiliary protection automatic power-off system; 2. The leakage-proof ground circuit with the leakage circuit breaker; and 3. The anti-air-burning system.

The aforementioned auxiliary protection power-off system is mainly for the abnormality of the line to the temperature is too high. And other abnormal conditions, in order to avoid the heating unit 40 failure (continuous heating) caused by excessive water temperature, therefore, the over temperature detector 53 is disposed on the water outlet 14, once the temperature of the outlet water is sensed to be higher than Celsius Above 70 ° C, the main control unit 20 immediately cuts off the power of the instant heating device 100 to achieve the effect of over-temperature protection. In addition, when the hot water has reached the set temperature, If the water is not used again for 5 minutes, the instant heating device 100 will automatically shut down to save energy and save electricity. When the forced heating button 71 is operated to force the heating to a set temperature, for example, if there is no hot water flowing out for 30 seconds, the instant heating device 100 is automatically turned off to avoid danger and power consumption.

The leakage preventing grounding circuit is combined with the earth leakage circuit breaker. As shown in FIG. 1, the grounding detector 53 and the power supply unit 80 are grounded by a potential difference to prevent leakage.

The air-proof burning system is installed in the water inlet 121 of the water chamber 12 (cold water inlet end), and the water inlet switch 30 is away from the setting of the temperature detector 51. When the water inlet switch 30 returns to the main control unit 20 for 2 seconds without a signal, the main control unit 20 will automatically turn off all the heating power immediately to prevent the water in the water chamber 12 from being drained, and the heating unit 40 remains Continue to warm up, causing the danger of empty burning.

The above descriptions are only a few preferred embodiments of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent changes and modifications made by the present invention in accordance with the scope of the patent application and the description of the invention, All should remain within the scope of this creation patent.
