を得ることができるようになる。According to the present invention, not only the combustion heat from the lower burner is transmitted to the food placed on the grill as a hot air flow, but also the heat flow rising from the lower part of the food is reduced. When the air is discharged from the exhaust port through the exhaust passage from the opening provided in the ceiling of the heating chamber, the ceiling surface of the heating chamber forming the exhaust passage wall is also heated at the same time. infrared radiation surface is heated that is formed on the surface, morphism Netsuho against the the food upper surface is carried out from the infrared emitting surface, the bottom bar
Waste heat from the burner is reused. The exhaust passage wall is open.
From the mouth to the exhaust port side, tilt downwards, that is, toward the object to be cooked.
Because of the slant, heat exchange between the hot air flow and the exhaust passage wall
Even if the temperature of the exhaust passage wall on the exhaust port side drops,
Can be compensated for by the closer distance of
Uniform heat radiation can be achieved. As described above, the object to be cooked can be heated from both the upper and lower surfaces only by the lower burner, so that not only the effective cooking space above the grill can be increased , but also the cooking device can be used.
Thermal efficiency can be improved . In addition, since the infrared radiation surface maintains a substantially uniform temperature due to the hot air flow, even when the object to be cooked is brought close to the infrared radiation surface, heat unevenness does not occur, and a good cooking result can be obtained.

可変することができる。In the above configuration, when the lower burner 15 is ignited, and at the same time air is blown into the air chamber 17 from the blower 16, the heat of the Bunsen flame formed by the lower burner 15 diffuses from the blower 16. The air flow diffuses into the heating chamber 8 from the outlet 18 of the heating chamber 8 as a hot air stream, and heats the lower portion of the object 12 on the grill 13 while moving the door 6 along the surface of the heating chamber 8 on the heating chamber 8 side. As a result, the air passes through an exhaust passage 10 through an opening 9 provided at a front portion of the ceiling of the heating chamber 8 and is discharged from the exhaust port 7 to the outside air. At this time, the hot air flow heats the lower exhaust passage wall 11 while passing through the exhaust passage 10 and raises the temperature of the infrared radiation surface 19. Furthermore, since the infrared radiation surface 19 also receives the convection heat in the heating chamber 8, its temperature reaches a high temperature of 400 to 500 ° C. or more on the opening 9 side, and starts radiating heat to the object to be cooked 12 below. . At this time, the hot air flow exchanges heat with the exhaust passage wall 11.
As the temperature decreases, the exhaust passage wall 11
Since it reaches the rear and is close to the object to be cooked 12, the object to be cooked 1
A substantially uniform heat radiation is provided on the upper surface of the second. In this way, the object to be cooked 12 is heated and cooked constantly and uniformly from both the upper and lower surfaces. As a result, even when the object to be cooked 12 approaches the infrared radiation surface, heat can be uniformly received, and the effective cooking space above the grill can be as large as 1.5 times as much as the conventional one. Can be. In addition, the food 12
The lower surface is heated by convection, and the upper surface is radiated by the reuse of the convection heat.
Thermal efficiency is more than 1.5 times higher than before
Can be maintained. Furthermore , the heating power of the entire heating chamber 8 can be changed only by changing the heating power of the lower burner 15.
