Abstract

An oven body includes a grilling chamber provided with several far infrared ray heaters and a smoking chamber that emits smoke from the charcoal heated by electric heaters, wherein the meat to be roasted is rotated in the grilling chamber by a rotating means, rotating alternately through a far infrared ray heating area where far infrared ray concentrates and through a smoking area where smoke concentrates, in which process the roasting operation by the far infrared ray and the smoking operation with particular scent of a charcoal are carried out simultaneously.

Claims

1. A charcoal smoke-far infrared ray radiating convection oven in which meat to be roasted is heated and roasted while being rotated by rotating plates, comprising:

a. a sealable grilling chamber provided with a plurality of far infrared ray heaters emitting far infrared rays for roasting meat in a heating area of said grilling chamber;

b. a smoking chamber partitioned from and disposed below the grilling chamber, said smoking chamber being provided with a plurality of electric heaters which generate far infrared rays and smoke from an organic fuel placed on said electric heaters, said smoke being discharged into a smoking area of the grilling chamber; and

c. an air circulating means including at least one air-circulating blower in fluid communication with an air supply blower that supplies air from an exterior of the grilling chamber, for convecting heated air and maintaining an equal distribution of temperature in the grilling chamber;

whereby the roasting by the far infrared rays and the smoking from the organic fuel are carried out simultaneously in the convection oven by rotating said meat sequentially through said heating area and said smoking area to produce a smoked and roasted meat.

2. The convection oven of claim 1, wherein the grilling chamber is provided with said plurality of far infrared ray heaters mounted at regular intervals on a ceiling and on a rear wall via supporting sockets in an interior of the grilling chamber.

3. The convection oven of claim 1, wherein the smoking chamber is partitioned from the grilling chamber by a heat-reflective bottom plate defining sloping sides;

further wherein the bottom plate includes a plurality of smoking holes for discharging smoke from the smoking chamber into the grilling chamber.

4. The convection oven of claim 3, further including a plurality of electric heaters arrayed in the smoking chamber for supporting and heating the organic fuel to create smoke.

5. The convection oven of claim 3, further including fat-removing means comprising with fat discharge holes in a central portion of the bottom plate at the bottom of the grilling chamber, through which fat separating from the meat during cooking is discharged into a fat receiving tray disposed under the bottom plate.

6. The convection oven of claim 1, further including a ventilator for discharging smoke and soot from the interior of the oven.

7. The convection oven of claim 1, wherein said air supply blower is mounted at a top portion of the oven body.

8. The convection oven of claim 7, wherein the air circulating blower is mounted at a top portion of the grilling chamber and the air supply blower and air circulating blower are placed in fluid communication via a tube.

9. The convection oven of claim 1, wherein the smoking chamber is disposed below the grilling chamber.

10. The convection oven of claim 2, wherein the plurality of grilling chamber far infrared ray heaters are mounted at a ratio of 2:

1 respectively on the rear wall and the ceiling of the grilling chamber.
