摘要： PURPOSE:To eliminate fire extinguishing noise that is generated at each cycle by reducing the fuel gas pressure when the flame reaches close to an extinction limit thereby suppressing fuel gas supply based on pressure rise in a cylindrical combustion chamber and finally stopping gas supply. CONSTITUTION:A multi-nozzle plate 8 is provided on the air supply side B at the end of the base of a cylindrical combustion chamber A, and a gas supply pipe 4 is directly connected to the gas nozzle 8a of the multi-nozzle plate 8, and at the same time to the air nozzle hole 8b of the multi-nozzle plate 8 an air supply pipe 5 is connected via an air chamber 9, and the gas supply pipe 4 is provided with a gas governor valve V3, and the air supply pipe 5 is also provided with a gas governor valve V4. The gas governor valve V3 is set at a low pressure and by reducing the fuel gas pressure, namely the gas supply pressure, the pressure in the pipe just before extinguishing flame exceeds the fuel gas pressure and stops the gas supply so that the energy of the flame is taken away rapidly and the flame is extinguished gently and silently.

SOLUTION: A gas grill is equipped with a heating chamber for accommodating stuff to be cooked and heating and cooking it with heat of combustion of a burner, a gridiron whereon the stuff is placed in the heating chamber and a receiver which is so provided below the gridiron as to receive the grease from the grilled stuff and slid in and out of the heating chamber together with the gridiron. In the course of pushing in the receiver 30, in this case, a contact part 8b of a fixed metal fitting 8 comes into contact with a U-shaped lower part 3j of a gridiron support frame 6 and rotates the frame 6 according to a pushed-in position, so as to raise the gridiron 20. In the course of pulling out the receiver, an engaging part 8c of the fixed metal fitting engages with the U-shaped lower part 3j of the gridiron support frame 6 and rotates the frame 6 according to a pulled-out position, so as to lower the gridiron 20.

摘要： PROBLEM TO BE SOLVED: To provide a main stop type water heater in which it is prevented from being frozen and damaged with a simplified structure even without drain operation and is again useable at all times. SOLUTION: Once ignition operation is applied to a main stop type water heater and water is supplied to a heat exchanger 1 through a water supply passage 3, a gate valve 9 opens a hot water output passage 5, and an atmosphere opening valve 8 interrupts hot water output passage 7 from the atmosphere, and further hot water heated with the heat exchanger 1 is guided to the flexible hot water output tube 5 for water output. Once the water supply is interrupted, the gate valve 9 confines the hot water in the hot water output passage 7, and the atmosphere opening valve 8 opens the hot water output passage 7 located downstream the gate valve 9 to the atmosphere, and further hot water existent downstream the gate valve 9 including the flexible hot water output tube 5 is substituted for air and is automatically drained to the outside of the apparatus. When predetermined temperature or lower is achieved, power is supplied to an electric heater 34 for heat production to insulate a water passage.

摘要： PROBLEM TO BE SOLVED: To improve quench performance by a flame trap. SOLUTION: When an ignition is effected in a grill chamber 11, flame is also spread to the exhaust port 15 side. Air induced by an equalizing plate 18 is sucked in an exhaust gas flow passage through an air hole 17 by a rise flow of exhaust gas and unburnt gas in an exhaust gas flow passage is burnt in a spot situated upper stream from a flame trap 16, whereby an amount of unburnt gas flowing out to an external part from the frame trap 16 is reduced. Further, by causing a flow of cold air induced by the equalizing plate 18 to a part of the flame trap 16, the increase of the temperature of the flame trap 16 is suppressed, whereby when unburnt gas flows through the flame trap 16, heat is absorbed to decrease temperature. Thus, flame can be quenched in a place above the flame trap 16 without re-igniting unburnt gas.

摘要： PROBLEM TO BE SOLVED: To make a solenoid operated type safety valve close in the case when the bottom of a cookpot is overheated or when a positive characteristic thermistor in a temperature sensor falls in a short-circuit failure, by a simple constitution, in a gas table heater equipped with the temperature sensor coming into contact with the bottom of the cookpot and with the solenoid operated type safety valve. SOLUTION: A gas table heater 1 is equipped with a burner 18, a thermal generation element 16 generating a thermal electromotive force by utilizing the burning of the burner, a boosting circuit 8 boosting the voltage of the thermal electromotive force on the basis of the oscillation of an oscillating part 9 and a storage battery 15 charged with the boosted thermal electromotive force. The oscillating part 9 is constructed of an astable multivibrator and conducts the oscillation dependently on the resistance value of a positive characteristic thermistor 11. In the case when the positive characteristic thermistor 11 reaches a prescribed temperature or when it falls in a short-circuit failure, the resistance value thereof changes and the oscillating part 9 stops the oscillation. Therefore boosting stops in the boosting circuit 8 and a solenoid operated type safety valve 12 is made to close.

摘要： PURPOSE: To detect easily a degree at which supply air and exhaust are clogged in combustion equipment and troubleshoot reduction in an air flow rate attributable to clogged supply air and exhaust air by installing a rotary operation control means or the like which turns a fan motor based on the rotary speed added during combustion time of combustion equipment. CONSTITUTION: An initial non-combustion time rotary speed of a motor 16a detected with a rotary speed detection means 17 when the fan motor 16a is driven at a definite electric current before the first combustion operation of combustion equipment 13 is detected. A differential rotary speed computation means is installed to compute the difference against a non-combustion time rotary speed of the fan motor 16a detected when the fan motor 16a is driven at a definite current. A rotary speed adding means is installed to add the computed differential rotary speed to the rotary speed during the combustion time of the combustion equipment 13. A rotary speed control means is installed, which turns the fan motor 16a based on the rotary speed added during the combustion time of the combustion equipment 13. This construction makes it possible to halt the operation of the combustion equipment 13 when the gas clogging has advanced during the supply and exhaust of air.
