May be used.

  The present embodiment is configured as described above. Next, the operation will be described by taking as an example the case where the sword fish is grilled as the object to be heated 30.

  Five sword fishes are arranged on the grill net 33, and the operation unit panel 5 is used to select the fish menu for cooking and start cooking. Then, the cooling fan 60 of the main body 2 operates and cooling air for cooling the inside of the main body 2 is sent. The cooking chamber starts heating by a plurality of heating process operations in which the upper and lower heaters 27 are incorporated in the controller 45 in advance. Simultaneously with the start of heating, the exhaust motor 36c also starts to operate.

  In the automatic cooking of roasted fish, the cooking time is adjusted by controlling the amount of food to be cooked during the process. The temperature detected by the temperature sensor 80 is taken into the control unit 45 after several minutes from the start, and then the temperature is measured again after a predetermined time, and the amount of the object to be heated 30 is determined by the temperature rise during the predetermined time.

  If the measured temperature rise value is larger than the temperature rise value incorporated in advance with cooking of three sword fish as a standard, the amount is determined to be small, and if the measured temperature rise value is small, the amount is determined to be large.

  When it is determined that the amount is small, cooking is completed by shortening the cooking time of each process incorporated in advance by the same amount according to the small amount. Conversely, as in the case of the five animals shown here, when it is determined that the amount is large, the cooking time of each process incorporated in advance is increased by the same amount according to the large amount, and cooked. To complete. Eventually, the cooking ends when all the heating steps are completed. Remove the baked sword fish from the grill 33.

  Here, the flow of the cooling air of the cooling fan 60 operating during cooking and the operation of the exhaust means 36 will be described with reference to FIGS. FIG. 8 is a view illustrating the upper surface around the cooking chamber and explaining the flow of the cooling air (the cooling air is indicated by an arrow).

  Air is sucked from the air inlet 7 by the cooling fan 60, and the cooling air blown by the cooling fan 60 passes through the inside of the duct 71 surrounding the substrate 70 and exits above the opening 71a. The heating coil unit 25 (not shown here) on the placement unit right 6a disposed above the opening 71a and the placement unit left 6b disposed on the partition plate 15 provided above the oven 4 simultaneously. Then, the heating coil unit 25 (not shown here) arranged in the mounting portion center 6c is cooled. Then, the air is exhausted from the exhaust port 8.

  Further, the cooling air is blown to the cooking chamber 26 from a side air inlet 43 b provided on the horizontal plate 4 b of the oven 4.

  Since the exhaust means 36 is also operating during cooking in the oven 4, cooling air is sucked from the front air inlet 43a and the side air inlet 43b toward the cooking chamber 26, and the sucked cooling air is exhausted. The bottom surface 31a of the tray 31 is cooled by the operation of the fan lower portion 36b, and is discharged out of the main body 2 through the exhaust outlet 8 from the lower exhaust outlet 29b.

  Further, smoke and odor generated from the object to be heated 30 are exhausted together with the cooling air sucked into the cooking chamber 26 from the front air inlet 43a and the side air inlet 43b by the operation of the upper exhaust fan 36a of the exhaust means 36. The air is sucked from the outlet 29a, purified, and discharged from the exhaust port 8 to the outside of the main body 2.

  As a result, an increase in pressure inside the main body 2 can be prevented, and at the same time, an increase in pressure in the cooking chamber 26 can also be prevented.

  The exhaust fan upper 36a has twice as many blades 36a1 as the exhaust fan lower 36b, and the angle at which the blades 36a1 are provided is inclined by 15 to 25 degrees with respect to the center (hole 36a2). The amount of air sucked and exhausted from the exhaust outlet upper 29a is increased with respect to the amount of air sucked from the outlet lower 29b. Therefore, the smoke and odor generated from the heated object 30 through the gap between the cooking chamber 26 and the door 32 are prevented from leaking. Further, smoke and odor are prevented from being exhausted from the exhaust outlet 8 without being purified by being sucked from the lower exhaust outlet 29b.

  Further, the exhaust fan upper 36a and the exhaust fan lower 36b arranged in the exhaust passage center 35c are not opened by the notch 36a3 formed by the blades 36a1 raised by the exhaust fan upper 36a. Since it is substantially closed by the portion 36b3, the air in the heating chamber 26 can be efficiently sucked through the exhaust passage upper portion 35a by the rotation of the exhaust fan upper portion 36a while being in the same space. The air in the heating chamber 26 can be efficiently sucked through 35b.

  According to the above embodiment, smoke and odor can be prevented from leaking from the gap between the cooking chamber and the door while maintaining cooking performance.
