Abstract

A hot-air cooker includes a housing including an internal ventilation conduit provided with an inlet and an 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 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 ventilation conduit and adjacent to the fan.

First claim

The invention claimed is:

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;
a rotary mixer installed in a bottom of the inner container;
a motor installed at the bottom of the outer container, and whose output shaft drives the rotary mixer, and
a heating plate located inside the cavity and crossed by the output shaft of the motor, the inner container placed on the heating plate, wherein the hot-air cooker is configured to heat foods by the heating plate and the resistor, at the same time and independently.

2. The hot-air cooker according to claim 1 , wherein the air outlet of the ventilation conduit is located above its air inlet, and a rim of the inner container is located below the air outlet of the internal ventilation conduit.

3. The hot-air cooker according to claim 1 , wherein a rim of the inner container is located above the air inlet of the internal ventilation conduit.

4. The hot-air cooker according to claim 1 , wherein the resistor is adjacent to the fan and is located above the fan.

5. The hot-air cooker according to claim 1 , wherein the air inlet and air outlet of the internal ventilation conduit are of the same height and also of the same width.

6. The hot-air cooker according to claim 1 , wherein the air inlet and air outlet of the internal ventilation conduit are of different heights and also of different widths.

7. The hot-air cooker according to claim 1 , wherein the fan is an axial fan or radial fan.

8. A hot-air cooker comprising:
a housing comprising an internal ventilation conduit provided with an air inlet and air outlet, the housing including an outer wall;
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 portion of the internal ventilation conduit abuts against the outer wall adjacent the fan;
a resistor, installed inside the internal ventilation conduit and adjacent to the fan;
a rotary mixer installed in a bottom of the inner container;
a motor installed at the bottom of the outer container, and whose output shaft drives the rotary mixer, and
a heating plate located inside the cavity and crossed by the output shaft of the motor, the inner container placed on the heating plate, and wherein the hot-air cooker is configured to heat foods by the heating plate and the resistor, at the same time or independently.

9. 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, the fan having an axis of rotation that is parallel or tangential to the inner container;
a resistor, installed inside the internal ventilation conduit and adjacent to the fan;
a rotary mixer installed in a bottom of the inner container;
a motor installed at the bottom of the outer container, and whose output shaft drives the rotary mixer, and
a heating plate located inside the cavity and crossed by the output shaft of the motor, the inner container placed on the heating plate, and wherein the hot-air cooker is configured to heat foods by the heating plate and the resistor, at the same time or independently.
