Abstract

PURPOSE:To obtain a good cooking result, by using a pipe-shaped section formed by a flame port plate and a bulkhead for a burner pipe into which primary air and a premixed gas flow, and adopting a pipe-shaped section formed by the bulkhead and a wind port plate as an air pipe. CONSTITUTION:An upper burner 21 and a burner pipe 17 installed to a burner device 16 are ignited. At the same time, air starts to blow into a burner pipe 17 in the blower device 17 and the air discharged from an air ejection port 11 flows out in a fixed direction along a wind direction control plate 18, thereby directing the direction of flames formed by a flame port 14 of the burner pipe 17 downward on a slant and allows the hot air to arrive near the central lower part of a toasting net 23, thereby maintaining a roughly unified environment temperature under the toasting net 23. At this point of time, the radiation heat is applied to a heated substance 22 in the lower part as well by the red heat on the surface of a metal net of the upper burner 21 so that the heated substance 22 may be uniformly and simultaneously heated from the upper and lower sides, thereby obtaining prompt, unified and good cooking result even in a wider heating chamber 20.
