Description

  The present invention relates to a gas stove with a pan bottom temperature sensor provided with a pan bottom temperature sensor protruding upward from an inner circumferential space of a burner formed in an annular stove burner.

  In general, in a gas stove including a stove burner having a large number of flame holes formed on the outer periphery, an ignition plug is provided near the outside of the stove burner to perform ignition by spark discharge. However, when an ignition plug is provided in the vicinity of the outside of the stove burner, boiled juice during cooking may adhere to the ignition plug and the ignition performance may be reduced.

  Therefore, a gas stove is known in which a pilot burner that forms a flame for igniting the stove burner is disposed below the stove burner (see, for example, Patent Document 1 below).

  In this gas stove, the stove burner is formed in an annular shape, and the flame of the pilot burner is formed to extend obliquely upward from below the inner space of the burner. Thereby, the flame of the pilot burner reaches the flame hole of the burner through the burner inner circumferential space, and the burner is ignited.

  According to the gas stove thus configured, the pilot burner and the spark plug that ignites the pilot burner are provided in a state of being hidden under the stove burner, so that the spilled juice is prevented from adhering to the spark plug and has good ignition performance. Can be obtained.

  By the way, in recent years, in a gas stove, in order to prevent overheating of a pan or the like during cooking, a pan bottom temperature sensor protruding upward from a burner inner circumferential space of the stove burner is provided (for example, refer to Patent Document 2 below). And also in a gas stove provided with a pan bottom temperature sensor, it is conceivable to prevent the simmered juice from adhering to the spark plug by providing the pilot burner.
