加熱ムラによる焼むらを解消することができる。In particular, since the rectifier fan 16, which is larger in outer diameter than the circulation fan 15, is coaxially and loosely mounted, the rectifier fan 16 directs the hot air from the circulation fan 15 to each hot air reversing portion 4b, 4c. Since the direction of the air is reversed to a substantially horizontal direction on the inclined surface of the oven 2, the vortices generated in the vicinity of each hot air reversing section 4b are eliminated, unlike conventional devices of this type, and uniform hot air is generated at t. As a result, the hot air in the heating chamber 10 is uniformly blown to the oven 2.
It is possible to eliminate uneven baking caused by uneven heating.
