るのである。 According to such a configuration, an operation button (not shown)
Push in and rotate to open a valve (not shown) provided in the middle of the gas supply pipe connected to the mixing pipe 1, and at the same time open the spark plug 13 using a piezoelectric element.
As a result, ignition occurs in the auxiliary combustion chamber 15, and ignition is performed in the outer flame hole 6 and the inner flame hole 4 by the auxiliary 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,
This keeps the valve open. A known structure for operating the valve using the thermocouple 21 is used. In such a case, the thermocouple 21
Even though the thermocouple 21 has entered the sub-combustion chamber 15 and the sub-combustion flame is ignited, the thermocouple 21 does not operate, and the thermocouple 21 operates reliably, causing the valve to close unexpectedly. There is no such thing. By forming a plurality of through holes 23 for the sub-combustion flame in the wall 22 of the sub-combustion chamber 15, ignition and accidental extinguishment of the sub-combustion flame are prevented. Further, in the sub-combustion chamber 15, a thermocouple 21 and a spark plug 13 for igniting the sub-combustion flame are arranged with an interval in the radial direction of the burner top 2. The space occupied by the burner top 2 in the radial direction is kept small, and the outer flame holes 6 are sufficiently formed in the outer peripheral part of the burner top 2.
Furthermore, the ignition plug 13 is disposed on the lower surface of the burner top 2 so as to be inside the thermocouple 21, thereby preventing boiling liquid from splashing on the ignition plug 13.

る。[Effects of the invention] In short, in the present invention, since the thermocouple and the spark plug for igniting the secondary combustion flame are arranged with a distance in the radial direction of the burner top, the thermocouple and the spark plug occupy The space in the circumferential direction of the burner top is kept small, a sufficient outer flame hole is formed on the outer periphery of the burner top, and the spark plug is placed on the bottom surface of the burner top so that it is inside the thermocouple. Therefore, there is an advantage that the boiling liquid can be prevented from splashing onto the spark plug.
