御が行えることを目的としたものである。However, in the above-mentioned conventional configuration, there is a large difference between the maximum gas flow rate regulated by the main nozzle 19 and the minimum gas flow rate during automatic temperature regulation regulated by the bypass nozzle 14. Since a rapid change in the gas amount occurs when the power of the temperature control solenoid valve 11 is switched between ON and OFF, a gas that can be manually squeezed by the power adjustment needle 16 to prevent fire extinguishing that burns out the flame of the burner 1 is generated. The gas flow rate regulated by the bypass nozzle 14 has to be increased by about 10 to 20% than the flow rate, and there is a problem that the thermal power throttle cannot be fully throttled during automatic temperature control. In addition, when adjusting the gas flow rate by automatic temperature control, a strong flame-a weak flame combustion is generated, which causes a sudden flame change and makes the user feel uneasy. There was also the issue that Further, during use of the gas cooker, it is necessary to always energize in order to keep one or more solenoid valves open, and there is a problem that power consumption is large.
The present invention is to solve the above problems, in the combustion control of gas combustion equipment, even during automatic temperature control, the burner can sufficiently reduce the heat power to a gas flow rate that does not extinguish the fire, and also during high temperature during automatic temperature control. Since the amount of gas can be changed without performing low-pressure combustion, the purpose of the present invention is not to cause a user to feel uncomfortable, to reduce annoying operation noise, and to reduce power consumption and control combustion.

きる。In the present embodiment, with the above-described structure, all that is required is to drive the rotating shaft 38 with the motor 50 to control the outflow, closing, and gas amount switching of the gas. Therefore, the power consumption required is only used when the motor 50 is driven when the gas is opened / closed and when the gas flow rate is adjusted, so the power consumption can be reduced.

滅火、バックファイヤー等が発生する恐れもない。Further, in this embodiment, by varying the voltage for driving the motor 50 via the control board 20, the range of thermal power adjustment by the thermal power setting means 27 is from the maximum gas flow rate 59 to the weak-weak gas flow rate 63. Even when the flow rate is large, the voltage applied to the motor 50 is increased and the inflow valve body 35 is increased from the maximum gas flow rate 59 to the medium-medium gas flow rate 62.
When the switching speed of the inflow valve is fast, the voltage applied to the motor 50 is lowered between the weak-medium gas flow rate 62 and the weak-weak gas flow rate 63, and the switching speed of the inflow valve body is controlled to be slow. Since the apparent gas flow rate is switched quickly and delicate adjustments are performed slowly, there is no risk of fire extinguishing of the burner or backfire.

4 and the valve body 43 having the inflow-side gas passage hole 34 and the outflow-side gas passage hole 39 are independently fixed by claw fitting, and the flow rate restrictor 57 is provided between the valve body 43 and the cock body 42. Since the cock outer wall 45 and the cock body 42 are joined by being sandwiched, the valve bodies 35 and 36 do not come off due to the pushing force of the spring 37 at the time of assembly and can be easily assembled.
