<p>[Problem to be solved] To improve the high heat efficiency by improving the heat transfer efficiency between combustion gas and a cooking container. [Solving means] The table burner 1 according to the embodiment allows combustion gas (including flame) to generally spout out from the flame port 17 of the burner 14 obliquely upward as if it twists in the burner circumferential direction. The combustion gas flows into multiple combustion gas routes partitioned in a spiral, and passes to the outside while making contact with trivet claws 22. That is, the combustion gas is discharged toward the outer circumferential direction along the bottom surface of a cooking container P while being guided by trivet claws 22 in a form of a convolute swirling flow. As a result, because in the combustion gas route, the combustion gas is constantly subject to the direction changing force and has the flow disturbed, a heat transfer border film is not formed on the bottom surface of the cooking container P, and the heat of combustion gas is successfully transmitted to the bottom of the cooking container P.</p> |
