Claims

[Scope of Claim for Utility Model Registration] A water flow detector that detects the water flow to the heat exchanger, a fuel variable means that varies the amount of fuel supplied to the burner, and a fuel variable means that uses the output of the water flow detector as a starting signal. an ignition sequence control means that adjusts the burner, performs an ignition operation for the burner and an ignition confirmation operation, and drives an alarm when the burner is not ignited;
After the temperature detector provided on the outlet side of the heat exchanger, the target temperature setter, and the ignition sequence control means are operated, according to the deviation between the output of the temperature detector and the output of the target temperature setter. In the combustion control device for a water heater, the water heater includes a temperature control means for adjusting the fuel variable means and bringing the deviation close to zero; means for storing the output of the temperature sensor as initial temperature data; and means for receiving the output of the water flow detector and storing the output of the temperature detector a certain period of time after starting the ignition operation of the ignition sequence control means as control temperature data. and a means for performing a comparison calculation to determine whether or not the control temperature data indicates a temperature increase equal to or higher than a predetermined temperature with respect to the initial temperature data; A combustion control device for a water heater, comprising means for stopping fuel supply to the burner and driving the alarm to stop operation of the water heater when a temperature rise is not indicated. .
