摘要： PROBLEM TO BE SOLVED: To improve the thermal efficiency and the combustion efficiency, and prevent a combustion noise from occurring, by arranging a plurality of recess-shape burner ports in a manner to surround the outer periphery of an internal wall, and also, arranging the central axes of the burner ports in a manner to tilt to the inside of the burner at a lateral specified angle or lower to the center of the burner. SOLUTION: In this inside flame burner, a combustion gas introducing space 8 to which a combustion gas is introduced from a mixing pipe, is formed between an external wall 7 and an internal wall 6. Also, the whole body of a burner upper surface 9 including the upper surface of a burner port 2 tilts so that the internal wall 6 may become lower. The burner port 2 which is arranged on the burner upper surface 9, is arranged by tilting as a whole in such a manner that the opening surface of the burner port 2 may face to the center of the burner, and an annular side wall 3b of the burner port 2 extends in the direction which is substantially orthogonal to the burner upper surface, and into the combustion gas introducing space 8. Individual burner ports are tilted at different optional angles within a range wherein the central axis 10 of the burner port is 90 deg. or lower in the lateral direction to the center of the burner, and the angle faces to the inside of the burner.

摘要： PROBLEM TO BE SOLVED: To improve the primary air ratio of a burner and contrive the improvement of combustion property as well as heating efficiency of the burner. SOLUTION: A gas nozzle 1 is provided on a regulator 6, attached to the mixing tube 5 of an internal burner port burner. The gas nozzle 1 injects fuel gas from an injection port 11, provided on the bore 10 of a tubular body 8. In accordance with the injection of the fuel gas, primary air is sucked from suction ports 12 on the outer periphery of the tubular body 8 into the bore 10 to join the primary air with the fuel gas and inject mixture from a tip end opening 9 against the burner. In this case, the center lines L2 of the suction ports 12 are slanted with respect to the center line L1 of the tubular body 8 by the angle of inclination θ1 within 30-60 degrees. According to this method, the flow passage resistance of the primary air, sucked into the bore 10 of the tubular body 8, is reduced and the primary air is joined with the fuel gas smoothly.

摘要： PROBLEM TO BE SOLVED: To overcome defects that the central heat distribution is deteriorated, unevenness in heating is generated and Chinese dishes requiring the large quantity of heating in the central part cannot be met because the flame holes of an inner burner and an outer burner are both provided outward and the number of the flame holes are increased in a burner realizing a high combustion using a conventional double burner having an outer ring burner and an inner ring burner. SOLUTION: A cooker burner 1 comprises a double burner having an inner ring burner 2 and an outer ring burner 3 to realize a high combustion. The inner ring burner 2 has the rate of primary air of 70% or more ad is provided with inward flame holes 10 for forming flame inward. The lower part of the inward flame holes 10 is closed by a closing part 17. The temperature of the flame formed by the inward flame holes 10 becomes high and the flame is assuredly blown upward and spreads in the periphery of a cooking appliance 5 along the lower surface thereof. The outer ring burner 3 heats the periphery of the cooking appliance 5 with its high heating power ad the high temperature flame of the inner ring burner 2 heats the wide rage of the inner side of the cooking appliance, so that the above mentioned inconveniences can be solved.

摘要： PROBLEM TO BE SOLVED: To perform rapid cooking and dishing up and to ensure safety by a method wherein a mount part is arranged at the upper surface part on the back side of a range table, an upper surface part on the front side forms a working surface, and during ignition, combustion is effected in a small flame rising from the inner peripheral wall of an annular part toward the mount part. SOLUTION: The upper surface part on the back side of a range table 10 forms a mount part 11, and the upper surface on the front side thereof forms a working surface 12. By performing rotation operation of a gas ignition plug 30, a gas is fed through an injection nozzle to a gas introduction part, and primary air is automatically sucked in a gas introduction part. Gas and primary air are mixed together and flow in an annular space, and injected through a through-opening to an internal space. Since a number of burner ports are formed in an inner cylinder part comprising an annular part, air is apt to be automatically sucked through a primary air suction hole. Gas is burnt in a small flame rising from the internal part of an inner cylinder part.

摘要： PROBLEM TO BE SOLVED: To improve the heat efficiency of a set burner. SOLUTION: This gas burner is constituted of large and small horizontal ring-shaped burners 2 and 3, each having flame holes on the inner circumference thereof. The small-diameter burner 3 is disposed in a blowby space at the center of the large-diameter burner 2 to supply a clearance 4 between both the burners 2 and 3 with secondary air from below by natural convection and the blowby space of the small-diameter burner 3 is cut by a closing member 5 off the secondary air from below, which allows setting of the optimum height of the flame of the small-diameter burner 3 sufficiently larger than the large-diameter burner 2. Therefore, the small-diameter burner 3 is installed at a position back from the large-diameter burner 3 to eliminate fear of burning loss of the small- diameter burner 3 as caused by the flame of the large-diameter burner 2 and moreover, the height of the flame can be set at a level to maximize the heat efficiency of both the burners 2 and 3.
