Description

  It has a gas supply part that mounts a cassette cylinder on either the left or right side, and the other three sides (front, back, and other side) are metal side plates that are provided with multiple air inflow holes necessary for combustion. The present invention relates to a stove including a piezoelectric ignition mechanism that is configured and provided with a burner that burns gas from a gas supply unit extending in a central portion between a front surface and a back surface and that can stably and surely ignite.

In a conventional stove (Patent Document 1) in which a burner for burning gas from a gas supply unit in a combustion chamber is extended to the center between the front surface and the back surface, as shown in FIG. The spark plug 2 of the ignition mechanism is screwed via a spark plug mounting plate 3 'above the position where the burner 4 of the separator 11 between the combustion chamber and the gas supply unit is mounted, and is provided at the tip thereof. The discharge electrode 2 a was arranged near the crater 4 a of the burner 4. For this reason, in manufacturing, it is necessary to finely adjust the distance between the spark plug and the crater of the burner, including the position where the spark plug mounting plate 3 is attached to the separator 11, and the spark plug mounting plate can be used over a long period of time. If the position of the spark plug becomes unstable due to, for example, loose mounting screws, the discharge target position of the spark plug also changes in an unstable manner, and the spark of the spark plug may not reach the crater of the burner, resulting in poor ignition.
Further, in the case of a cylindrical burner, the crater is biased to one of them due to loosening of a fixed screw or the like, and there is a possibility that the thermal power distribution in the combustion chamber is unbalanced.
