The one described in Japanese Patent No. 4707 is generally used. As shown in FIGS. 8 (a) and 8 (b), this burner has a structure in which a combustion plate 81 made of a ceramic molded body having a large number of irregularities and a flame port on a combustion surface is housed in a burner main body 82. However, the combustion surface glows red due to surface combustion on the combustion surface, and emits radiant heat.

Japanese Patent Application Laid-Open No. 54107/54. As shown in FIG. 9, this burner heats an aluminum-plated steel plate provided with a large number of flame ports to form a combustion plate 91 on the surface of which an infrared radiation film made of an alloy layer of iron and aluminum is formed. And radiated heat was radiated from the infrared radiation film heated by the surface combustion in the combustion plate.

果が得られなかった。However, in the conventional burner, since the ceramic molded body is used as the combustion plate 81, the thickness of the combustion plate becomes about 12 to 14 mm in order to prevent mechanical strength and flashback. In addition, the thickness of the entire burner was as thick as 25 mm or more. Therefore, when such a burner is used in a baking cooker, the inside height of the baking oven is limited, and not only the rise of heating is delayed by the heat capacity of the combustion plate, but also due to the shift to a low combustion amount. CO was apt to be generated due to a decrease in the temperature of the combustion plate, and as a result, weak drawability was reduced, and good cooking results could not be obtained.

As a method, an aluminum-plated steel sheet is heated to form an infrared radiating film made of an alloy layer of iron and aluminum on the surface.Aluminum-plated steel sheet has the best corrosion resistance in the non-heated state, The alloy layer of iron and aluminum formed after heating tends to be microscopically porous, and the steel plate portion of the base material is partially exposed on the surface. In particular, there was a tendency that the base material was completely exposed in the portion where the flame opening was formed, and the corrosion resistance itself was lowered. Further, the combustion plate 91
In addition to generating squeak noise due to thermal expansion or shrinkage at the time of fire extinguishing due to surface burning, the peeling of the alloy layer is promoted, the overall corrosion resistance is reduced, and such a burner was used for a baking cooker. If you use it for a long time,
There has been a problem that the flame opening portion is corroded, and clogging and conversely, the flame diameter is increased and a flashback is likely to occur.

を減少させることができる。According to the above invention, the thickness of the combustion plate is extremely thin as compared with the ceramic combustion plate, and the infrared radiation film is formed on the combustion surface. Therefore, excessive red heat due to heat accumulation on the combustion surface can be prevented. When this burner is used as an upper burner in a baking cooker, not only can the inside height be secured sufficiently, but the heat capacity of the combustion plate is small, so that the temperature rises quickly and the amount of CO generated by shifting to a low combustion amount decreases. As a result, a wide range of squeezing can be widened, and a good baking cooker that can support a wide range of cooking menus can be obtained. Further, as the material of the combustion plate, austenitic stainless steel of 18% or more of Cr and 18% or more of Ni is used, so that corrosion resistance can be ensured even when used for a long time. Furthermore, since one end of the combustion plate is slidably sandwiched between the partition plates via a cushioning material, gas leakage is prevented, stress due to repeated thermal expansion and contraction is absorbed to ensure durability, and at the same time, squeaking noise Can be reduced.
