Hot-air cooker

1. A hot-air cooker comprising:

a housing comprising an internal ventilation conduit provided with an air inlet and air outlet;

an outer container, installed inside the housing;

an upper cover, installed above the outer container; the outer container and the upper cover constituting a cavity, the air inlet and outlet of the internal ventilation conduit communicating with the cavity;

an inner container, located inside the cavity;

a fan, installed inside the ventilation conduit;

a resistor, installed inside the internal ventilation conduit and adjacent to the fan;
