摘要： PURPOSE:To provide a positive flame transfer by a method wherein a pilot burner for performing a flame transfer adjacent to an upper burner and a lower burner forming a continuous combustion surface is provided, the lower burner is formed with an air blowing passage and a combustion secondary air is supplied to the pilot burner. CONSTITUTION:An air blowing device 11 is integrally fitted to a lower burner 8 and formed with it so as to constitute a burner unit 12. At a central part of a flow branch part 114 of an air pipe 112 is formed an air blowing part 116 for supplying a combustion secondary air to a pilot burner 18. An upper burner 7 and a lower burner 8 are formed such that each of a pair of right and left burners is formed by a continuous combustion surface and a pilot burner 18 having a flame rod 20 is adjacent to the combustion surface, so that a positive flame transfer can be attained. Since the secondary combustion sir for the pilot burner 18 is supplied from an air blowing part 116, the combustion is not influenced by the exhaust gas ignited at a flame transfer hole 84 of the lower burner 8 and there is no bad combustion state.

摘要： PURPOSE:To prevent the wetting of an ignition electrode by means of gravy, by a method wherein the outer size of an auxiliary burner is increased over the size of a central hole, an ignition electrode is disposed in the central hole and in a position lower than the outer size of the auxiliary burner to cover it with the auxiliary burner, and the upper surfaces of the auxiliary burner and a main burner are inclined outwardly. CONSTITUTION:An auxiliary burner 4 is formed with an auxiliary burner body 11, an auxiliary burner cap 12 is placed on the auxiliary burner body 11, and is disposed on a central hole 3. A leg 13 of a main burner 2 is engaged with a leg hole 15 of a main burner support 14. The size of an outer part 16 of the auxiliary burner 11 is decreased over that of the size of the central hole 3, and the size of the auxiliary burner cap 12 is increased over that of the central hole 3. Upper surfaces 17 of the main burner cop 10 and the auxiliary burner cap 12 are both inclined outwardly, and an ignition electrode 5 is formed below an auxiliary burner body 11. Since gravy doe not flow in the central hole 3, the interior of a gas kitchen range 6 is prevented from contamination and corrosion, and the ignition electrode 5 is prevented from the occurrence of poor insulation from the auxiliary burner 4 due to getting wet by gravy.

摘要： PURPOSE:To surely keep safety and enable positive combustion in a combustion device such as hot water heater by a method wherein a fuel valve is kept open during a desired auxiliary time after ignition and this auxiliary time is extended by a desired time when ignition of a burner is confirmed. CONSTITUTION:First and second fuel valves 12A and 12B are opened under a pushing operation of a hot water feeding member 16 to its deepest position and then a pilot burner 11 is ignited. At this time, an initial opening valve holding circuit 22A of a control circuit 22 may output an auxiliary time until the opened valve of a first fuel valve 12A can be kept with an electromotive force of a first thermocouple 19 heated by a pilot burner 11 so as to assure the opened valve of the fuel valve 12A. If the ignition is confirmed with a flame rod 25 within this auxiliary time, a forced valve opening holding electrical power is supplied for a desired time. With this arrangement, it is possible to make a positive ignition while keeping safety characteristic.

摘要： PURPOSE:To prevent the intrusion of broth into the inside of an appliance by a method wherein at a gas cooking stove with an ignitor a port for ignition is installed between a burner and a cover and also a guide which is located outside the burner and below the port for ignition and of which end part faces a pan for the broth is installed. CONSTITUTION:An ignition flame generated from an ignition burner 19 passes through a notched part 18 formed at the side wall 17 of a guide 15 and is guided from a port 12 for ignition to the top of a cover 11 and ignites gases discharged from flame holes 14. Even if over-boiled broth falls down from the port 12, the broth is guided to a pan 6 for the broth by the guide 15 and its intrusion into a gas cooking stove can be prevented.

摘要： PURPOSE:To prevent over-spilled dew from entering an equipment during its use by a method wherein an ignition hole of a cover is cooperatively related with the operation of a knob to open the hole only when an igniting operation is to be performed. CONSTITUTION:When a knob 3 is pushed to rotate, gas is injected from an ignition nozzle 17, a spark is generated by an ignition plug 18 and then an ignition flame is formed by an ignition burner 16. At this time, pushing operation for a knob 3 causes a cooperating rod 12 to be added with a pushing force, the cooperating rod 12 may cause a cover 10 to be rotated through a fixing plate 13. At this time, an ignition hole 11 is moved to correspond with a pace over a groove 9 of a burner main body 5, the groove 9 is made to communicate with the ignition hole 11, the ignition flame is passed and then gas injected from the flame hole 7 is ignited. After ignition, a force for the knob 3 is removed to cause the cooperating rod 12 to be pulled toward an operator, the cover 10 is rotated and the ignition hole 11 is closed by a stepped part 8. As a result, it is possible to prevent over-spilled dew from entering the equipment and the like.
