不良を招かない。For this reason, when the thermocouple 3 and the ignition electrode 4 are arranged at an interval only in the radial direction (the distance is 6 m).
m), it is possible to increase the linear distance (15 mm) between the two, so that at the time of ignition, spark discharge reliably occurs on the lower surface side (distance is 3 mm) of the electrode 42-site 104, and does not cause poor ignition. .

A wall 216 protrudes downward (in the range of about 20 °) in a fan-like shape on the lower surface of one.
【００４３】この為、点火の際に、開口１０５から放出

全体の着火性が悪くなる。It should be noted that the ignition flame is applied to the window 10 from below the portion 104.
6 to a position above the part 104,
When the mixture is discharged from the flame formed by the protruding pieces 211 and 213 in the vicinity, if there is no gap between the upper surface of the part 104 and the lower end of the wall 216, the mixture is directly fired from the ignition flame. Burner A, because it has to be transferred
The overall ignitability deteriorates.

こんろバーナＡ全体の着火性が良い。However, since a gap is provided as in the present embodiment, an ignition flame ignites an air-fuel mixture (shown by a dotted line in FIG. 5) which goes out of the gap, and through the ignited flame, Since it is possible to ignite into the air-fuel mixture coming out of the flame formed by the raised piece 211 and the raised piece 213 near the part 104,
The ignitability of the entire burner A is good.

The eaves 21 are located near the outer periphery of the lower surface of the portion 21.
2 is projected downward, so that the ignition electrode 4 is hardly boiled.
