Abstract

The present technology provides a multi-purpose cooking apparatus that provides simultaneous smokeless grilling for food products and air frying for food products utilizing the same fan and heating elements. A lower portion of the apparatus includes an enclosed air fryer cooking chamber with a closable door. The air fryer cooking chamber is heated with heating elements and a fan for blowing heated air through the cooking chamber. The upper portion of the apparatus utilizes the same upper heating elements as the air fryer chamber and includes a grilling surface, such as a grilling plate, in an enclosed interior cooking environment. The fan pulls air from the upper portion, filters smoke from the air, and returns the air to the lower portion of the apparatus. The heated, smokeless, circulated air from the fan is used to air fry in the lower portion.

Claims (29)

1. A multi-chamber cooking apparatus, comprising:

an apparatus body comprising a first cooking chamber and a second cooking chamber;

at least one heating element controlled by the apparatus, wherein the at least one heating element is positioned between the first cooking chamber and the second cooking chamber so as to be able to generate heat within both the first and second cooking chambers for cooking food as can be provided within one or both of the first and second cooking chambers; and

a fan operatively positioned in fluid communication between the first and second cooking chambers, wherein air from the first cooking chamber is drawn to an inlet to the fan and an outlet of the fan is directed to the second cooking chamber.

2. The apparatus of claim 1 , wherein the at least one heating element heats the first cooking chamber and the second cooking chamber simultaneously.

3. The apparatus of claim 1 , wherein the second cooking chamber includes an air frying crisper basket in which food products are air fried by heated air circulated in the second cooking chamber by the fan.

4. The apparatus of claim 1 , wherein the first cooking chamber includes a grilling plate that grills food products.

5. The apparatus of claim 4 , wherein when a lid is placed on the first cooking chamber, a first cooking chamber cooking environment is substantially sealed such that the air leaves the first cooking chamber environment primarily via vent inlet holes when drawn by the fan.

6. The apparatus of claim 4 , wherein the at least one heating element is in contact with the grilling plate in the first cooking chamber.

7. The apparatus of claim 4 , wherein heated circulated air from the second cooking chamber is drawn by the fan into the first cooking chamber via holes in the grilling plate.

8. The apparatus of claim 4 , wherein the grilling plate heated elements have an uneven surface to create score marks in the food items.

9. The apparatus of claim 1 , wherein the at least one heating element is a resistive heating coil.

10. The apparatus of claim 4 , wherein a lower portion of the grilling plate comprises holes to allow liquids to flow from the lower portion of the grilling plate.

11. The apparatus of claim 9 , further comprising a liquid reservoir to collect the liquids that flow from the lower portion of the grilling plate.

12. The apparatus of claim 1 , further comprising a filter to remove smoke from the air.

13. The apparatus of claim 12 , wherein the filter is located between the first cooking chamber and the fan.

14. The apparatus of claim 1 , wherein the second cooking chamber includes a baking pan for baking food products.

15. The apparatus of claim 1 , wherein the fan and the at least one heating element is controlled by a control panel with a user interface that receives user inputs.

16. The apparatus of claim 1 , wherein the first and second cooking chambers are independently accessible, the first cooking chamber by way of a first closure element and the second cooking chamber by way of a second closure element, so that cooking can be done in either of the first and second cooking chambers or in both the of the first and second cooking chambers at the same time.

17. A multi-chamber cooking apparatus, comprising:

an apparatus body comprising a first cooking chamber and a second cooking chamber;

at least one heating element controlled by the apparatus, wherein the at least one heating element is positioned between the first cooking chamber and the second cooking chamber so as to be able to generate heat within both the first and second cooking chambers; and

a fan operatively positioned in fluid communication between the first and second cooking chambers, wherein air from the first cooking chamber is drawn to an inlet to the fan and an outlet of the fan is directed to the second cooking chamber,

and further wherein second cooking chamber includes an air frying crisper basket in which food products are air fried by heated air circulated in the second cooking chamber by the fan.

18. A multi-chamber cooking apparatus, comprising:

an apparatus body comprising a first cooking chamber and a second cooking chamber;

at least one heating element controlled by the apparatus, wherein the at least one heating element is positioned between the first cooking chamber and the second cooking chamber so as to be able to generate heat within both the first and second cooking chambers; and

a fan operatively positioned in fluid communication between the first and second cooking chambers, wherein air from the first cooking chamber is drawn to an inlet to the fan and an outlet of the fan is directed to the second cooking chamber,

and further wherein the second cooking chamber includes a baking pan for baking food products.
