The main flame hole, the ignition flame hole, the thermocouple flame hole, and the flame transfer flame hole are connected and mounted on the same surface, and the burner head is press-molded with a step difference from the mixed gas supply port installation surface. It is a thing.

Further, in order to achieve the second object, according to the present invention, the ignition flame hole of the burner cap, and the flame transfer flame hole mount so that the thermocouple flame hole and the main flame hole are connected and mounted. The mounting surface is formed radially.

[0010]

According to the present invention, the main flame hole mounting surface of the burner head, the ignition flame hole, the thermocouple flame hole mounting surface, and the fire transfer flame hole mounting surface are arranged on the same plane. Moreover, since the step is formed above the installation surface of the mixed gas supply port,
The strength of the burner head can be improved, and the deformation after pressing is eliminated. In addition, the burner flame hole part of the burner cap has a simple shape, and the moldability is improved, and the mounting fitability with the burner cap on the upper surface of the burner head is improved, resulting in good ignition performance, fire transfer performance, and combustion performance. You can get a stove burner. In addition, the burner head mounting surface of the burner head is provided radially, so that the flame of the transfer flame hole forms a radial flame as well as the main flame hole, and cooking performance with good heat distribution can be obtained. Is.
