Description

Burners for gas stoves and gas stoves

The present invention relates to a burner for a gas stove, and a gas stove equipped with the burner for a gas stove; And the annular lower burner part is concentric with the upper burner part.

Conventionally, as this kind of burner for a gas stove, there is known the constitution of an internal flame type burner, which is to make the upper burner part and the lower burner part have a plurality of burners in the radial direction on the inner peripheral part at intervals in the circumferential direction. A burner with an inner opening (for example, refer to Patent Document 1). In addition, in this type of burner for a gas stove, the diameter of the inner peripheral portion where the burner port of the lower burner portion is opened is smaller than the inner diameter of the bottom wall portion of the upper burner portion.

However, when the cooking vessel heated by the burner of the gas stove boils over, the overflowing soup drips down the bottom surface of the cooking vessel. In addition, in the conventional burner for a gas stove, the overflowing soup that drips down the bottom surface of the cooking vessel tends to adhere to the burner port of the lower burner portion. And, because it is difficult to touch its lower burner portion with hands and is difficult to clean, so there is a risk of overflowing soup sticking to and accumulating on the burner of the lower burner, causing the burner to be clogged.
