It is a sectional view seen from the front along. Inside the outer box 1, a heating chamber 6 is formed by a ceiling 2, side walls 3, a bottom plate 4, a rear wall 14, and a door 5. A gas burner 7 is disposed below the heating chamber 6 and extends in one direction from the front (that is, the door 5 side) to the rear (that is, the fan 19 side that will be described later).
is formed. The bottom plate 4 includes a partition plate 1 that forms a hot gas flow path 9 whose vertical cross section is an inverted triangle when viewed from the front.
0 is provided downward toward the center, and the gas burner 7 is arranged directly below the ridgeline 11 of this partition plate 10. The gas burner 7 has flame holes above or on both sides. A large number of ventilation holes 12 are bored near the ridgeline 11 of the partition plate 10 along the ridgeline.
At the back of the heating chamber 6 when viewed from the front, a guide plate 13 extending diagonally upward from the bottom plate 4 is fixed, and a rear wall 14 extending upward is connected to the end of this guide plate. A space forming plate 16 that forms a guide passage 15 communicating with the hot gas flow path 9 is fixed below the guide plate 13 . The upper end of the guide passage 15 faces the entrance of a fan 19, such as a Sirotskov fan, which has a horizontal axis at the rear end of the heating chamber 6. This fan 19
From there, there is a central suction port 20 formed in the rear wall 14.
Hot gas is blown into the heating chamber 6 through the blowing ports 21 formed on both sides of the heating chamber 6 .

てフアン１９が駆動される。 A gap 22 is formed on both sides of the bottom plate 4 between the bottom plate 4 and the side wall 3, and the heating chamber 6 and the combustion chamber 8 communicate with each other through the gap 22. The lower part of the combustion chamber 8 communicates with the outside through a combustion air inlet 23 formed at the bottom of the outer box 1. An exhaust duct 24 is provided in the upper part of the heating chamber 6. The duct 24 has an exhaust port 25 that opens downward at the upper center of the heating chamber 6 at one end thereof, and the other end of the duct 24 communicates with the outside from the upper part of the outer box 1 through an opening 32. are doing. This duct 24 has a duct 27
are connected, and the exhaust port 30 of this duct 27
is open toward the heating chamber 6 at the upper part of the rear wall 14. The opening area of the duct 27 is
The opening area of the exhaust port 25 is smaller than that of the exhaust port 25. A throttle plate 26 is provided below the exhaust port 25 for changing the opening area of the exhaust port 25 facing the heating chamber 6 and for blocking the exhaust port 25. This aperture plate 26 is arranged horizontally along the lower surface of the duct 24 and is fixed to a rotating shaft 31 having an axis. This rotating shaft 31 passes through the ceiling plate 2 and is fixed to the operating lever 28. Therefore, by swinging the operating lever 28, the aperture plate 26 can change the opening area of the exhaust port 25. When the aperture plate 26 completely closes the exhaust port 25, the operating lever 28 operates the micro switch 29, and the operation of the micro switch 25 drives the fan 19.

７を経て開口部３２を経て外部に放散される。 When quickly heating the food loaded into the heating chamber 6, operate the operating lever 28 to close the diaphragm plate 26.
As a result, the exhaust port 25 is fully closed, and at this time, the fan 19 is driven by the operation of the micro switch 29. Therefore, the hot gas from the burner 7 of the combustion chamber 8 flows from the vent hole 12 of the partition plate 10 to the hot gas passage 9 and the guide passage 15, as shown by the broken line arrow.
After that, it is blown into the heating chamber 6 from the blowing port 21 by the fan 19 . Since this blow-in port 21 is provided at one end of the upper part of the heating chamber 6, the hot air is forced to circulate within the heating chamber 6 by convection, thereby making it possible to quickly heat the food to be cooked. A part of the circulating hot gas is transferred from the gap 22 of the bottom plate 4 to the combustion chamber 8.
The remaining hot gas is discharged from the exhaust port 30 to the duct 2.
7 and the opening 32 to the outside.

することが可能になる。 As described above, according to the present invention, the hot gas from the combustion chamber can be forcedly circulated in the heating chamber by convection using the fan provided at the end of the heating chamber, so that the food to be cooked can be quickly heated. In addition, this fan is stopped and hot gas is guided from the combustion chamber to the heating chamber through both sides of the bottom plate of the heating chamber 6 by natural convection, thereby slowly heating the food to be cooked. Such cooking speed can also be adjusted by means of an openable and closable exhaust port provided in the upper part of the heating chamber. In particular, according to the present invention, the porous partition plate 10 is extended below the bottom plate 4 along the gas burner 7 extending in one direction, and the porous partition plate 10 is provided above the gas burner 7, thereby separating the bottom plate 4 and the porous partition. Board 10
By driving the fan 19 , the entire amount of hot gas generated over the entire length of the gas burner 7 is sucked into the hot gas flow path 9 and passed through the fan 19 . Therefore, it is blown into the heating chamber 6 and circulated by forced convection. Therefore, as described with respect to the prior art described above, the problem of overheating of the food on both sides of the bottom plate 4 is solved by the present invention, and it is possible to heat the food with uniform temperature distribution. become.
