ある。 According to such a configuration, an operation button (not shown)
is pushed in and rotated to open a valve (not shown) provided in the middle of the gas supply pipe 25 connected to the mixing pipe 1, and the ignition device 13 using a piezoelectric element ignites the sub-combustion chamber 15. ,
Ignition occurs in the outer flame hole 6 and the inner flame hole 4 by the secondary combustion flame. Then, when the user releases the operating button, the operating button is returned by the spring force, and the valve attempts to return to the closed state by the spring, but the thermocouple 21 receives heat from the ignition state of the secondary combustion flame. , the electromotive force suppresses the operation of the valve in the closing direction and maintains the valve in the open state.
A known structure for operating the valve using the thermocouple 21 is used. In such case,
The thermocouple 21 has entered the sub-combustion chamber 15,
Even though the secondary combustion flame is ignited, the thermocouple 21 will not operate, and the thermocouple 21 will operate reliably to prevent the valve from closing unexpectedly.

In summary, the present invention uses a mixing tube made of sheet metal,
A through hole is formed that opens only at the top and bottom of this mixing tube, and a series of hanging walls are hung on the lower surface of the outer periphery of the burner top, with the lower end surface of the hanging wall facing the upper surface of the periphery of the through hole. A space surrounded by a wall can be used as a sub-combustion chamber, and by making simple improvements to the sheet metal mixing pipe and burner top, the sub-combustion chamber can be easily constructed. It is possible to prevent rotation, and the sub-combustion chamber is formed on the bottom of the burner top, so there is no risk of boiling liquid splashing onto the ignition device that penetrates the through-hole in the sub-combustion chamber from below, and accidentally extinguishing the sub-combustion chamber. The advantage is that it can be eliminated.
