摘要： PROBLEM TO BE SOLVED: To permit the detection of operation of a gas amount regulating lever without adding any different member to the gas flow rate regulating lever. SOLUTION: The flow rate of gas supplied to a gas burner is regulated by a gas flow rate regulating lever 23. A thermocouple 22 is arranged near the burner port of the gas burner while the presence of flame on the gas burner and the flow rate of gas supplied to the gas burner are judged based on the output voltage of the thermocouple 22. A timer 10a starts the counting operation of the same simultaneously with the ignition of the gas burner and when a change, overriding a set threshold value in a gas amount judging means 10c, is generated in the output voltage of the thermocouple 22, the timer 10a is re-triggered. When the limited time of the timer 10a is finished, a safety valve 11, inserted on the supplying route of fuel gas to the gas burner, is closed whereby the fire of the gas burner is extinguished.

摘要： PROBLEM TO BE SOLVED: To ensure safety upon failure of a flow control valve without sacrifice of convenience. SOLUTION: Temperature of a cooking container heated by the gas burner 1 of a combustor is detected by means of a temperature sensor 2. When the detected temperature reaches a sustaining temperature (230 deg.C) at the time of frying, a heating control means 13 controls fire force of the gas burner 1 such that the detected temperature is kept in the vicinity of the sustaining temperature (230 deg.C) for a predetermined time (2 min). When the detected temperature reaches a stop temperature (255 deg.C) before the predetermined time elapses due to open failure of a flow control valve 5, the gas burner 1 is put out. When the stop temperature is not reached, a temperature setting means 14 sets the stop temperature and the sustaining temperature at 270 deg.C and 245 deg.C, respectively. Subsequently, the heating control means 13 controls fire force of the gas burner 1 such that the detected temperature is kept in the vicinity of the sustaining temperature (245 deg.C).

摘要： PROBLEM TO BE SOLVED: To extremely rapidly control a fan motor to a proper state when a fan motor is controlled so that an airflow is adjusted to a target value. SOLUTION: A target airflow relational formula, by which an airflow amount by a fan 15 is adjusted to a target airflow and which indicates the relation between the number of revolutions of fan and a target applying voltage applied on a fan motor 45, is stored. The number of revolution of fan detected by a sensor for the number of revolutions 47, and a deviation εn between a target applying voltage Vs determined by the target airflow relational formula and a present applying voltage Vo detected by a voltage detecting part 48, are determined. An applying voltage applied to the fan motor 45 is varied and adjusted in a state that the more the deviation εn is increased, the more a variation regulation amount is increased so that the deviation εn is decreased.

摘要： PROBLEM TO BE SOLVED: To perform an effective protection of a connected location between a rigid pipe at a hot water discharging pipe and a flexible pipe while keeping a superior aesthetic appearance of the hot water discharging pipe section in a hot water boiler. SOLUTION: There is provided a hot water boiler, in which a rigid pipe section 3 extended out of a main body 1 of a hot water boiler and a flexible pipe section 4 connected to the extremity end of the rigid pipe section 3 form a hot water discharging pipe 2. The hot water discharging pipe 2 is covered by a bellows-like flexible cover 8, wherein the flexible cover 8 is applied as a cover having a bellows structure over a substantial full length of the hot water discharging pipe 2, a bellows cylindrical section 8a placed at a corresponding position of a connecting section covering a connected location between the rigid pipe section 3 at the hot water discharging pipe 2 and the flexible pipe section 4. Near its forward or rearward section of the flexible cover 8 is a bellows-like cylindrical section having a higher rigidity against a bending operation of the flexible pipe 4 than that of a bellows-like cylindrical part 8b, at the extremity end covering the flexible pipe 4 at the extremity end of the hot water discharging pipe rather than the location near the connecting part.
