Therefore, if the burner top is made smaller in diameter than the annular part of the mixing tube, combustion inhibition due to the upward flow of secondary air that flows up the annular part can be avoided, but the boiling liquid may drip onto the top surface of the large-diameter annular part. There was a problem that this boiling liquid and dirt entered the outer flame hole formed on the outer periphery of the burner top and clogged the outer flame hole. In order to solve this problem, the
-123741 and Japanese Utility Model Application No. 60-2139 have been proposed, but they are unable to maintain a continuous annular flame in the outer flame hole of the burner top.

is pushed in and rotated to open a valve (not shown) provided in the middle of the gas supply pipe 26 connected to the mixing pipe 1, and ignite the ignition device 13 in the sub-combustion chamber 15 using a piezoelectric element. conduct,
Ignition occurs in the outer flame hole 6 and the inner flame hole 4 by the secondary combustion flame. Then, when you release your hand from 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 ignition state of the secondary combustion flame is received by the thermocouple 21, and the electromotive force thereof 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 a case, even though the thermocouple 21 has entered the sub-combustion chamber 15 and the sub-combustion flame is ignited, the thermocouple 21 will not operate, and the thermocouple 21 will operate reliably.
This prevents the valve from being closed unexpectedly.

てある。 In the present invention, the outer diameter of the burner top 2 is made smaller than the outer diameter of the annular part 9 of the mixing tube 1; This makes it possible to avoid inhibition of combustion in the outer flame hole 6 due to the upward flow of secondary air flowing along the outer periphery of the annular portion 9. Furthermore, by forming an inclined surface 25 on the upper surface of the outer circumferential portion of the annular portion 9 so that it becomes downward toward the outside, the broth and dirt dripping onto the upper surface of the annular portion 9 are discharged outward and downward along the inclined surface 25. The outer flame hole 6 is prevented from being clogged with boiling liquid or garbage.
Then, the inclined surface 25 is brought to the outer lower surface of the outer flame hole 6 to form a flame holding gap c between the outer lower surface of the outer flame hole 6 and the inclined surface 25, and the outer lower surface of the outer flame hole 6 and the inclined surface are formed. The flame holding gap c between the surfaces 25 allows the flame holding to be formed in a continuous annular shape. The outer flame hole 6 at the outer peripheral portion of the combustion chamber 6 is designed so that combustion can be performed satisfactorily.

In summary, in the present invention, the outer diameter of the annular part of the mixing tube on which the burner top is mounted is made larger than the outer diameter of the burner top, so that the external flame is caused by the upward flow of secondary air that climbs along the outer periphery of the annular part. While it is possible to avoid combustion inhibition in the hole, an inclined surface is formed on the upper surface of the outer peripheral part of the annular part, and this inclined surface is continuous with the outer lower surface of the outer flame hole formed in an annular shape. Since a flame-holding gap is formed between the outer lower surface of the outer flame hole and the sloped surface, the boiling liquid and dirt that dripped onto the upper surface of the annular part will flow along the sloped surface and be discharged outward and downward. The outer flame hole will not be clogged with boiling liquid or garbage, and the flame holding gap between the outer lower surface of the outer flame hole and the inclined surface can form a continuous ring shape.
The outer flame hole on the outer periphery of the burner top allows for good combustion, and when the flame is extinguished by cutting off the supply of fuel gas by operating the operation button, cold secondary air flowing up the annular part flows through the outer flame hole. This has the advantage of being able to eliminate any remaining fire in this area.
