Then, when the water temperature is raised to a preset high temperature, the controller 2 closes the intake valve 333 to extinguish the combustion ports without heating the water storage tank 12, and the controller 2 opens the water outlet valve 17 to start supplying heat. water. When the water temperature drops to a preset low temperature, the controller 2 turns on the igniter 321 and the intake valve 333 to ignite the combustion port again, further heating the burner 31 to the water storage bucket 12 again, and the combustion sensor 322 again Begin to sense whether the ignition is successful and trace back to the above steps, and continue to cycle according to the above steps to achieve the purpose of controlling the water temperature.

Referring to FIG. 5, when the combustion sensor 322 senses the ignition failure, it can be divided into two conditions. First, when the ignition failure time has not exceeded the preset ignition time, the controller 2 continues to turn on the igniter 321 The ignition is continued with the intake valve 333, and once the combustion sensing 322 senses that the ignition is successful, the controller 2 turns off the igniter 321 and enters the water temperature control cycle described in the previous paragraph. Second, when the ignition failure time exceeds the preset ignition time, the controller 2 turns off the igniter 321 and the intake valve 333, which is an extremely important safety protection mechanism, and can prevent the igniter 321 from continuously igniting excessively. Power consumption, second, closing the intake valve 333 can prevent gas fuel from leaking out, and further prevent accidents such as carbon monoxide poisoning or explosion caused by gas fuel leakage, and then open the alarm 8 to notify the user, so that the user The invention can be immediately known and the invention can be checked immediately. If the inspection is completed and there is no problem and can be used continuously, the user can press the zero setting button to return the invention to the controller 2 to re-open the igniter 321 The intake valve 333 and the water inlet valve 16 and the step of closing the water outlet valve 17, whereby the present invention can be returned to the normal use state.
