However, when the fan case 62 of the fan assembly 60 is configured in the shape of a hexagonal pillar, the discharge is discharged to the bottom, left, and right, and the case is shown to be switchable at an angle of approximately 90 degrees. You can also change the discharge direction for each angle. However, it is not limited to this, and the discharge direction of the discharge duct 70 can be easily changed by configuring the fan case 62 in a different shape as needed.

When the discharge duct 70 is directly connected to the fan 61 and the discharge direction of the discharge duct 70 is changed, a connection passage between the fan 61 and the discharge duct 70 must be provided, so there are at least two connections in the flow path. Bending occurs.

In the cooking appliance 1 according to an embodiment according to the present disclosure, air flows into the fan case 62 of the fan assembly 60 rather than the fan 61, so that the connection duct 50 is connected to a certain suction connection portion 63. Even if it is connected to , there is no difference in what is discharged to the discharge duct 70 through the discharge connection 64. The location where the fan 61 and the discharge duct 70 are connected always remains the same as the discharge connection portion 64. Accordingly, even if the direction in which the air sucked into the fan assembly 60 is discharged to the discharge duct 70 is changed, the flow path is not bent and flow resistance can also be reduced.
