This may provide better smoke extraction while not causing too much of an “air fry” effect on the food when the cooker 9100 is the grill configuration.
- the cooker 9100 may operate the air flow generator 9600 at another speed that is smaller than the second speed, for example, when the cooker 9100 is in a bake mode.
- the air flow may be kept lower than the second speed (e.g., as low as possible).
- the bake mode may be substantially identical to the air fry mode except that the air flow speeds are different.
- the user can select whether the air flow generator 9600 is on (e.g., the user can choose a smoke extraction on the user control panel 9830).
- the circuitry 9810 may be configured to keep the air flow generator 9600 off when the cooker 9100 is the grill configuration.
- the user can change the cooker 9100 from the grill configuration (see FIG. 10) to the air fry configuration (see FIG. 11) by replacing the grill plate 9400 with the air fry basket 9500 that includes the air fry bottom plate 9501.
- the user can change the cooker 9100 from the air fry configuration (see FIG. 11) to the grill configuration (see FIG. 10) by replacing the air fry basket 9500 that includes the air fry bottom plate 9501 with the grill plate 9400.
- the cooker 9100 automatically determines which of the grill plate 9400 and the air fry bottom basket 9500 or the air fry bottom plate 9501 are present in the cooker, and may automatically operate in the appropriate mode or otherwise present a user with appropriate options at the user control panel 9830.
