With the above configuration, most of the combustion gas of the main burner 17 passes through the inside of the heating pipe 14 and is discharged from the open end 14a to one end side inside the heating chamber 14, and a part of the combustion gas is above the ejection holes 19, 19 ... The combustion gas after being discharged to the inside of the heating pipe 14 moves in the direction opposite to the inside of the heating pipe 14 and is discharged to the outside from the exhaust gas port 8a through the exhaust gas pipe 8 in the process. It will heat one or two oils. Therefore, the high temperature combustion causes the open end 14 of the heating tube 14 to
Since the inside of the heating chamber 11 is always filled with the gas as it moves from the a to the exhaust gas port 8a, the oil tanks 1 and 2 are uniformly heated from the lower surface side. Further, generally, the temperature of the combustion gas is lowered toward the end of the passage, but in this case, in the heating cylinder 14, the temperature gradient becomes higher on the burner side, while the heating cylinder 14
Outside, since the temperature gradient becomes lower toward the exhaust gas port 8a side, the temperature difference between both ends in the heating chamber 11 is reduced by heat exchange between the combustion gas inside and outside the heating cylinder 14, and in addition, a large number of ejection holes are formed.
Since high-temperature combustion gas is also discharged and supplied from 19, 19, ...
The temperature in the upper part of the heating chamber 11 becomes substantially uniform.
Further, since the combustion gas is filled in the heating chamber 11 covered with the heat insulating material once and then discharged to the outside through the only exhaust gas port 8a,
The thermal efficiency becomes extremely high, and the heat release and heat radiation to the surroundings of the deep fryer are very small, and the working environment is greatly improved compared to the conventional one.
