摘要： PURPOSE:To simplify the operation by providing a valve and its plunger opening and closing a fuel passage which are regularly energized in the direction cutting the fuel passage, an attracting winding for opening the valve, a holding winding for keeping the attracted state, and a battery applying a voltage to the both windings. CONSTITUTION:A plunger 3 has a valve 4 for supplying and cutting gas on its top end, which valve is energized in the direction closing a gas passage 6 by a coil spring 5. When a voltage is applied to an attracting winding 1 of low impedance by a battery, an attracting force acts on the plunger 3 in the direction minimizing the magnetic resistance of magnetic closing loop, namely against the force of the coil spring 5 to open the valve 4. Once the plunger 3 is attracted, the magnetic resistance is reduced, and the same magnetic flux can be generated by a small magnetomotive force. As the attracting force is increased in inverse proportion to the square of distance, the sending of a small current only to a holding winding 2 suffices for keeping the attracted condition.

摘要： PURPOSE:To make it possible to automatically use a blower in a preceding state after using a hot water feeder, and to improve the convenience for use of the blower by storing the condition of the blower preceding the use of the hot water feeder in the case where the hot water feeder is used under the condition of a range being hood used, in which the blower is operated. CONSTITUTION:Whether a blower 29 has been in 'low' rotation or in 'high' rotation is determined as a range hood has been in use before a hot water feeder operation switch is turned ON. When it has been in use, the storage of data of the condition of the range hood used before using a hot water feeder A is retained, and the hot water feeder A is brought into a state of 'low' or 'high' combustion and further the blower 29 is switched over to a 'high' rotation. Then, whether the range hood data on the 'low' or 'high' rotation condition of the blower 29 prior to the use of the hot water feeder A is available is determined. When the data is available, the 'high' rotation of the blower 29 is switched over to the 'low' or 'high' rotation preceding the use of the hot water feeder A on the bases of the storage of the data on the range hood, and subsequently the blower 29 is rotated.

摘要： PURPOSE:To obtain a burning appliance without risk in which exhaust gas reversely flows in a living house by providing a burning stop device for closing an electromagnetic valve by a nonoperation signal of a fan operation detector other than a burning control element and detecting an accident of the fan operation detector at the operation start time of a fan motor. CONSTITUTION:An electromagnetic valve 16 is opened to burn a burner 24. Since a wind pressure switch 12 is closed, a burning stop circuit which is a valve closing circuit 27 is formed so that the base of a transistor 21 is H, a collector is L, the collector of a transistor 19 is H, the transistor 19 is in an OFF state and not concerned with the drive of the electromagnetic valve 16. Just after the output of a fan operation output part 22a, the wind pressure switch 12 is checked for a T2 time, if the wind pressure switch is short-circuited, a burning stop device 22d is actuated to close the electromagnetic valve 16 and combustion is not performed. If an accident should happen in a fan operation detector such as the wind pressure switch and a microcomputer, burning is stopped to prevent exhaust gas from flowing into a living house reversely.

摘要： PURPOSE:To obtain a burning appliance without risk in which exhaust gas is reversely flowed in a living house by providing a valve closing circuit for closing an electromagnetic valve by a nonoperation signal of a fan actuation detector other than a burning control main element, and confirming whether the stop of the fan is immediately after a fan motor stops during the stop state of the fan motor to detect an accident of a fan actuation detector. CONSTITUTION:An electromagnetic valve 16 is opened to burn a burner 24. At this time, since a wind pressure switch 12 is closed, a valve closing circuit 27 is formed so that a base of a transistor 21 is H, a collector is L, a collector of a transistor 19 is H, the transistor 19 is in an OFF state and they are not concerned with the drive of the electromagnetic valve 16. If an accident should happen in a microcomputer 22 and a fan motor, when the wind pressure switch 12 is turned off, the base of the transistor 21 is L, charged in a capacitor 20, the base of the transistor 19 is H, the collector is L and a transistor 18 is turned off to close the electromagnetic valve 16. Thus, in the case where a trouble happens in the microcomputer 22 which is a main burning control main element by a valve closing circuit 27, the safety of a burning appliance is maintained.

摘要： PURPOSE:To permit the visual confirmation of ignition by an operator indirectly while standing up, by a method wherein the ignition is informed of by indication when the thermal electromotive force of a thermocouple provided in a combustion unit has become a given value or higher, thereafter, the indication is extinguished when a given time has elapsed. CONSTITUTION:When there is no thermal electromotive force in a thermocouple T, the output of a comparator 34 shows H-level by resistors 8, 9, 10. However, when the thermal electromotive force of a given value or higher is generated, the plus input voltage of the comparator 34 is reduced and the output of the same is converted into L-level. Accordingly, transistors 27, 31, 30 are operated and a LED 32 is lighted. The transistors 26, 29 are operated simultaneously with the lighting of the LED 32, therefore, the discharge of a charge from a capacitor 35 is started. When the voltage of the capacitor 35 has become lower than a voltage, set by the resistors 10, 20, (after a given time (t)), the output of the comparator 33 shows H-level and the LED 32 is put OFF.

摘要： PURPOSE:To prevent a fault such as a fire hazzard or the like by stopping the supply of a fuel by a microcomputer when an ignition key is short-circuited for a predetermined period of time, and further making it impossible to use the apparatus in its entirety when the ignition key continues to be short-circuited in the burning apparatus such as a gas range for home use. CONSTITUTION:When it is assumed that an ignition key 9a included in a key matrix 9 is in a short-circuited state, a central processor 15 judges that the ignition key 9a judged by a key reading judging part 14 is continuously inputted, and sends a signal to a timer 11 thereby to start counting. When the central processor 15 judges that the time where the ignition key 9a is in a short- circuited state is a predetermined time T1 in comparison in a comparison part 11a, a signal is sent to switching means 2 through a motor position monitoring part 17 and motor control circuit means 3, whereby only a burner 1 is automatically fire-extinguished. Further, when the ignition key 9a continues its short- circuited state for a time longer than a predetermined time T1, and the central processor 15 judges that the count of the timer 11 is a predetermined time T2 in comparison in a comparison part 11a, a solenoid valve 4 is closed and the entire part of the apparatus is rendered inoperable.

摘要： PURPOSE:To improve the safety of the controller by providing a safety circuit so that the combustion is stopped when an automatic return type fuel control valve operating switch is short-circuited, in the controller of the gas heater and the like. CONSTITUTION:When a fire-extinguishing button 9 is depressed and hand is off, a microcomputer 20 discharges an igniter (not shown), opens a motor cock 15 and a solenoid valve 14, and feeds a gas to a burner to ignite the gas. After the passage of a predetermined time, for example, five second after depressing the fire-extinguishing button 9, the microcomputer 20 again reads the signal from the fire-extinguishing button 9. At this time, if the fire-extinguishing button 9 is continued to be depressed, the safety circuit 21 of the microcomputer 20 acts to put the motor cock 15 at a closed position, and further the solenoid valve 14 is opened to stop the combustion. By this construction, unexpected combustion due to the turning ON of an inadvertent switching operation can be prevented and the safety of the controller is realized.
