摘要： PROBLEM TO BE SOLVED: To reduce the thermal effect to other furniture by a method wherein the right and the left of a cabinet are closed with a side plate, and a lower space is provided between a cooking appliance on the lowermost shelf and a floor surface, and a side space is provided between the right and left side surfaces of each cooking appliance and the side plates of the cabinet, and those spaces are made to communicate, and air for fuel is fed to each cooking appliance from the lower space through the side spaces. SOLUTION: On the right and the left of a cabinet, side plates 9, 9 are attached, and radiation heat to the sides from respective cooking appliances 41, 42, 43, is shielded by the side plates 9, 9. A side space 9a is provided between respective side plates 9 and respective side surfaces of the cooking appliances 41, 42, 43, and the side spaces 9a are made to communicate with a lower space 5G, and air for combustion for respective cooking appliances 41, 42, 43 is fed from an opening through the lower space 5G and the side spaces 9a, and is drawn into the appliances from air inlets 41a, 42a, 43a. By this method, in addition to the heat shielding action by the side plates 9, a cooling action by the air for combustion which runs in the side spaces 9a, can be obtained, and a thermal effect to other furniture by the heat of the side walls can be reduced as much as possible, and other furniture can be surely prevented from being deformed.

摘要： PURPOSE:To prevent damage to the vicinity of the fixing part of a gas burner and simplify the fixing structure of the gas burner by slidably fitting the upstream side open end of a burner pipe onto a nozzle and flattening the downstream end of the burner pipe to close it thereby fixing the downstream end. CONSTITUTION:A gas burner comprises a burner pipe 21 and a heating plate 22. The burner pipe 21 comprises a metal pipe one end of which is opened and the other end of which is flattened and closed. The closed end 23 is threadedly fixed to a rear machine 11 provided along the wall in the rear wall of a hearth 10 and the open end is fitted over a nozzle 24 placed in a feed air device so as to be supported thereby. The pipe 21 and heating plate 22 expand thermally when in use, however, the closed end 23 of the pipe 21 only is fixed threadedly and the open end is only fitted over the nozzle 24, so that any thermal expansion can be absorbed.

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.
