Reference numeral 9 denotes an air outlet provided at an upper portion on the outer side of the plate 4 and blows air substantially toward the center of the plate 4; 10 denotes an air passage for guiding exhaust air 11 from the centrifugal fan 7 to the air outlet 9; 9 is an exhaust port provided near the exhaust port 9 for discharging a part of the exhaust air 11 to the outside of the body.

Reference numeral 13 denotes blown air, 14 denotes suction air, and 15 denotes oil smoke.

16 is a filter holding means, 17 is a fixing means for fixing the filter holding means 16 below the heating means 5 and on the suction side of the suction means 7, and 18 is a filter holding means 16 inserted from the side of the equipment body 19. It is an insertion slot for doing. Reference numeral 20 denotes an electric motor provided on the outer peripheral portion of the air passage 10, and reference numerals 21 and 22 denote pulleys connected to the centrifugal fan and the electric motor, respectively. A belt 23 connects these two pulleys and transmits the driving force of the electric motor to the centrifugal fan. And these pulleys 21,
The drive transmission means is formed by the belt 22 and the belt 22. This drive transmission means corresponds to a so-called winding transmission device, and other methods may be used among the generally known winding transmission devices.

The operation of this embodiment will be described below.
When the heating means 5 is energized, the plate 4 is heated. As a result, the food such as meat placed on the plate 4 is heated and cooked. At this time, the oil coming out of the food and the oil applied to the plate 4 before cooking are also heated, and the oil smoke 15 is generated.
On the other hand, the suction air 14 sucked by the centrifugal fan 7 driven by the electric motor 20 is discharged from the suction means 7, becomes the exhaust air 11, and a part thereof is formed in the exhaust port 12.
Through the aircraft. The remaining exhaust air that has not been discharged passes through the air passage 10, is guided to the air outlet 9, and is blown out from there toward the approximate center of the plate 4.

At this time, the exhaust air 1 is
1 is discharged outside the fuselage, the blown air 13

However, if the blown air 13 has a larger air volume than the suction air 14, the blown air 13 collides with each other near the center of the plate 4 and a part of the blown air 13 Without being sucked from above, the oil smoke rises while entraining the oil smoke above the plate 4. That is, since a part of the exhaust air 11 is exhausted from the exhaust port 12 to the outside of the machine, the air volume of the intake air 14 can be made larger than the exhaust air 13, and the entire exhaust air 13 can be reliably sucked together with the oil smoke. .

Further, by discharging a part of the exhaust air 11 to the outside of the airframe, the temperature of the entire ventilation path from the intake port 6 to the blowout port 9 is moderated, and all the components in the ventilation path are provided. Can be set low.

Particularly, in this embodiment, since the electric motor 20 is not directly connected to the centrifugal fan but is provided on the outer peripheral portion of the air passage 10 via the drive transmitting means, the height of the device main body 19 can be reduced. In addition, since the distance between the electric motor 20 and the heating means 5 can be increased, excessive temperature rise of the electric motor can be prevented, and the difference between the frequency of the commercial power in East Japan and the frequency in Japan in Japan, or the frequency of the commercial power between The rotational speed of the centrifugal fan 7 can be kept constant only by changing the reduction ratio of the pulleys 21 and 22 for the difference.
