摘要： PROBLEM TO BE SOLVED: To solve such a problem that the flame of a cooking-stove burner 12 is sucked in the cooking-stove main body 11 via an air intake 74 at a drip pan 7, which may have thermal influence upon the electric wiring or other parts within the cooking-stove main body, in case that an air flow occurs such as that upper air is sucked in a cooking-stove body 1 by the pressure difference arising between the interior of the cabinet of kitchen furniture and the outdoors, in a built-in cooking-stove for a system kitchen. SOLUTION: This built-in cooking-stove is provided with cover material 54 which surrounds the burner body, forming the second opening 52 between itself and the body 12a of the cooking-stove burner 12, and also covers the top of the source receiving pan 7, forming the third opening 53 between itself and a roof 4. In this case, the area of each of the second and third openings and an air intake is set so that the third opening may be the largest and that the air intake may be the smallest.

摘要： PROBLEM TO BE SOLVED: To provide an internal burner port burner capable of judging that an erroded hole happens without permitting a flame to blow off downward even when a bottom member that closes a lower side of an internal burner port is erroded owing to cooked soup, etc., to form a hole. SOLUTION: A wall surface 7b of a burner body 7 is disposed below a bottom member 6 through a gap S. More specifically, a lower side of an internal burner port 5a is formed as a double structure of the bottom member 6 and the wall surface 7b. For this, even when an erroded hole is formed in the bottom member 6, a flame blown off downward from the bottom member 6 is blocked with the wall surface 7b to ensure high safety. Since the flame blows off upward in an abnormal state, a user is informed of the formation of the erroded hole from the state of the flame. In contrast, mixture air flows through the gap S. Thus, uneven supply of the mixture air is eliminated. Further, since the bottom member 6 is cooled with the mixture air, heat dissipation of a flame hole ring 5 is excellent, and hence durability of the burner port ring 5 is improved.

摘要： PROBLEM TO BE SOLVED: To improve the heating efficiency in a cooking stove in which the leakage of a flame or hot air to the outside of a grate is restrained by providing a cylindrical grate for surrounding the flame of a burner, and an exhaust fan for forcibly sucking and exhausting the hot air generated by the flame from the space surrounded by the grate. SOLUTION: A burner 5 is formed of an inside flame type ring burner, and an annular overhanging member 42 overhanging radially inward from a grate 3 is provided between the grate 3 and the burner 5. The flame F of the burner 5 rises via the opening 42b of the inner periphery of the member 42, and the flame F and hot air flow radially outward in the upper space of the member 42 by the suction force of an exhaust fan 7. A protrusion 42c for disturbing the rectilinear propagation of the flame and hot air radially outward is provided on the upper surface of the member 42 to increase the contact time of the flame and hot air with the bottom of a pan.

摘要： PURPOSE:To carry out an ignition action smoothly. CONSTITUTION:When a pilot burner 41 is ignited, the flame is guided upwardly so that the flame is guided into a space between a burner pipe 21 and a hot plate 22 from an opening 45 through the outer periphery of the burner pipe 21. A fan 30 is turned on a certain time period before this ignition action and simultaneously with the ignition action, a gas circuit to a nozzle 24 is opened, so that a fire is transferred to an air-gas mixture delivered from burner ports 25, 25 formed on the pipe 21 to bring a gas burner 2 into a burning state. In this manner, since a flame of the burner 41 is caused to penetrate deeply into the gap between the pipe 21 and the plate 22 along the outer periphery of the pipe 21 so that ignition action can be conducted, and even if lateral air flow is produced, ignition action of gas burner can be carried out surely.

摘要： PURPOSE:To prevent the dispersion of burning rate over a burner port of a burner pipe by making the size of the burner port located on the side of the end of the burner pipe smaller than that of a burner port located nearer to the base side. CONSTITUTION:A large number of burner ports 25 are arranged in a longitudinal direction spaced apart a predetermined distance over the top surface of each burner pipe 21 and a plurality of auxiliary burner ports 26, 26 are formed near a closed end 23. A group of burner ports of the burner pipe 21 is divided into a first burner group on the upstream side 25a, 25a, a second group in the intermediate area 25b, 25b, and a third group on the downstream side 25c, 25c, and diameters of burner ports are made smaller gradually from the upstream side toward the downstream side. Consequently the distribution of amount of blowing gas in the case of burner ports of the same diameter is corrected, so that the amounts of gas blown off from each of the groups can be equalized.

摘要： PROBLEM TO BE SOLVED: To improve heat drawability from a heat shut-off cylinder without impairing heat resistance of the cylinder surrounding a pot bottom temperature sensor. SOLUTION: A ceramic coating layer 8a having high heat insulation is formed on an outer periphery of a heat shut-off cylinder 8. Even when the cylinder 8 is formed of material having high heat conductivity such as aluminum or copper or the like to upgrade heat conductivity, the insulation of the cylinder 8 is ensured. And, to suppress heat radiation from an inner periphery of the cylinder 8 to a pot bottom temperature sensor 7, a ceramic coating layer 8c is formed on an inner periphery of the cylinder 8. To improve the conductivity, a mounting bracket 80 for the cylinder is coupled to an unprocessed metal exposed part 8b of the cylinder 8.

摘要： PROBLEM TO BE SOLVED: To suppress heat transfer from a trivet to a top plate by forming a plurality of projections to bring a lower end of an outer circumferential wall of the trivet into contact with the top plate at a plurality of parts in the circumferential direction on either of the lower end of the outer circumferential wall of the trivet or the top plate. SOLUTION: An inner circumferential wall 31 of a trivet 3 is loaded on an upper surface of an inner top plate 21, and an outer circumferential wall 30 of the trivet 3 is loaded on an upper surface of a circumferential edge part of an opening 20a of an outer top plate 20. A plurality of claw-shaped projections are formed on the lower end of the outer circumferential wall 30 of the trivet 3 with a clearance in the circumferential direction, and the claw-shaped projections 33 are abutted on the upper surface of the circumferential edge part of the opening 20a of the outer top plate 20. The contact area of the outer circumferential wall 30 of the trivet 3 with the outer top plate 20 is greatly reduced compared with the contact area of the arrangement in which the lower end of the outer circumferential wall 30 is brought into contact with the outer top plate 20 over the whole circumference, and the heat transfer from the trivet 3 heated by the hot air to the outer top plate 20 through the outer circumferential wall 30 can be suppressed.
