Abstract

Embodiments of the present disclosure relate to an air-based flyer, comprising: a food preparation chamber ( 1 ); an air moving device ( 2 ) for moving air in the food preparation chamber to generate air flow; a heating device ( 3 ) for heating the air flow generated by the air moving device ( 2 ) so that the heated air flow can heat the food; an air filter ( 4 ) adapted for filtering air from the food preparation chamber ( 1 ). The air-based flyer according to the present disclosure avoids discharging fume into the surroundings, and can take away water vapor generated upon cooling timely and improve the cooking quality.

Claims (27)

1. An air-based fryer, comprising

a food preparation chamber;

an air moving device for moving air in the food preparation chamber to generate air flow;

a heating device for heating the air flow generated by the air moving device so that the heated air flow can heat food that in use may be received in the food preparation chamber;

a liquid based air filter adapted to filter air from the food preparation chamber, the liquid based air filter comprising a liquid tank comprising an air outlet above a liquid level, wherein the food preparation chamber has an air outlet which is in fluid communication with the liquid tank so that air from the food preparation chamber entering the liquid tank rises above the liquid level in the liquid tank; and

an air pumping device, wherein the air outlet is disposed above the liquid level and is in fluid communication with the air pumping device to build negative pressure in a space above the liquid level in the liquid tank through the air pumping device.

2. The air-based fryer according to claim 1 , wherein the air pumping device is in fluid communication with surroundings so that filtered air from the air outlet is at least partially discharged into the surroundings.

3. The air-based fryer according to claim 1 , wherein the air pumping device is in fluid communication with the food preparation chamber so that filtered air from the air outlet is at least partially circulated into the food preparation chamber.

4. The air-based fryer according to claim 1 , wherein the liquid tank is detachably connected to the food preparation chamber.

5. The air-based fryer according to claim 1 , wherein the air moving device is adapted to create an air circulation path in the food preparation chamber, and the heating device is located in the air circulation path so as to heat the air moving in the air circulation path.

6. The air-based fryer according to claim 1 , wherein in the food preparation chamber is provided a food receiving structure having an air permeable bottom, a top opening and sidewalls, the air moving device and the heating device are located in a vicinity of the top opening of the food receiving structure such that a circulation path is created by the air moving device in such a way that air comes into the food receiving structure from the air permeable bottom of the food receiving structure, and exits the food receiving structure from the top opening of the food receiving structure, and then moves along the sidewalls of the food receiving structure to the air permeable bottom of the food receiving structure.

7. The air-based fryer according to claim 1 , wherein the air filter comprises a porous section located below the liquid level in the liquid tank.

8. The air-based fryer according to claim 7 , wherein the air outlet is in fluid communication with a space of the liquid tank upstream of the porous section so that air from the food preparation chamber flows through the porous section.

9. The air-based fryer according to claim 7 , wherein the porous section comprises an element having a plurality of holes to allow air flow only through the holes.

10. An air-based fryer, comprising

a food preparation chamber;

an air moving device for moving air in the food preparation chamber to generate air flow;

a heating device for heating the air flow generated by the air moving device so that the heated air flow can heat food that in use may be received in the food preparation chamber;

a liquid based air filter comprising a liquid tank detachably connected to the food preparation chamber, the liquid based air filter being adapted to filter air from the food preparation chamber, wherein the food preparation chamber has an air outlet which is in fluid communication with the liquid tank so that air from the food preparation chamber entering the liquid tank rises above a liquid level in the liquid tank; and

an air pumping device, wherein the air pumping device and the air moving device are driven by a same actuator, and the liquid tank further comprises has an air outlet above the liquid level, which is in fluid communication with the air pumping device to build negative pressure in a space above the liquid level in the liquid tank through the air pumping device.

11. The air-based fryer according to claim 10 , wherein the air pumping device is in fluid communication with surroundings so that filtered air from the air outlet is at least partially discharged into the surroundings.

12. The air-based fryer according to claim 10 , wherein the air pumping device is in fluid communication with the food preparation chamber so that filtered air from the air outlet is at least partially circulated into the food preparation chamber.

13. The air-based fryer according to claim 10 , wherein the air filter comprises a porous section located below the liquid level in the liquid tank, and the porous section comprises an element having a plurality of holes to allow air flow only through the holes.

14. The air-based fryer according to claim 13 , wherein the holes have a diameter smaller than 2 mm.

15. The air-based fryer according to claim 10 , wherein the liquid tank is detachably connected to the food preparation chamber.

16. The air-based fryer according to claim 10 , wherein the air moving device is adapted to create an air circulation path in the food preparation chamber, the heating device is located in the air circulation path so as to heat the air moving in the circulation path.

17. The air-based fryer according to claim 10 , wherein the air moving device is adapted to create an air circulation path in the food preparation chamber, and the heating device is located in the air circulation path so as to heat the air moving in the circulation path.
