Abstract

An air cooking device includes a main unit and a drawer structure, wherein the main unit is provided with an internal cavity, and the drawer structure includes a drawer panel and a frying bucket fixed on the back side of the drawer panel. The drawer structure can be pushed into the cavity to perform the operation of air frying cooking. The main unit includes a top wall above the cavity, and the air cooking device also includes a sealing element, with the sealing element being provided between a mouth portion of the frying bucket and the top wall of the cavity to prevent oil fumes in the frying bucket from escaping between an edge of the mouth portion of the frying bucket and the top wall of the cavity.

First claim

The invention claimed is:

1. An air cooking device comprising:
a main unit provided with an internal cavity, the main unit having a top wall above the cavity;
a drawer having a drawer panel and a frying bucket fixed on the back side of the drawer panel, the drawer being removably insertable into the cavity to perform air frying cooking; and,
a sealing element surrounding a mouth portion of the frying bucket to prevent oil fumes from being discharged from the frying bucket between the mouth portion of the frying bucket and the top wall of the cavity;
wherein the main unit is provided with an upwardly pushing structure positioned in a rear portion of the cavity, which lifts the drawer upwards upon insertion into the cavity, thereby establishing a seal between the mouth portion of the frying bucket and the top wall of the cavity.

2. The air cooking device of claim 1 , wherein the sealing element is assembled on an edge of the mouth portion of the frying bucket, and the sealing element is sealed with the top wall.

3. The air cooking device of claim 2 , wherein:
the main unit includes a bottom wall below the cavity,
the upwardly pushing structure extends from the bottom wall into the cavity, and
when the frying bucket is inserted into the cavity, the upwardly pushing structure pushes up the frying bucket, so that the sealing element and the top wall can form a seal.

4. The air cooking device of claim 3 , wherein the upwardly pushing structure includes a first supporting portion and a guiding surface extending obliquely and downwardly from the first supporting portion, to guide the frying bucket to move to abut against the first supporting portion.

5. The air cooking device of claim 4 , wherein the main unit includes a second supporting portion for supporting the drawer panel.

6. The air cooking device of claim 4 , wherein the frying bucket includes a guiding inclined surface, wherein during the process of pushing the frying bucket into the cavity, the guiding inclined surface moves along the guiding surface.

7. The air cooking device of claim 1 , wherein:
the frying bucket includes a bottom and an air exhaust port arranged at the bottom,
the air cooking device further comprises an air exhaust box, the air exhaust box having an air inlet, an air outlet, and a cooling flow channel connecting the air inlet and the air exhaust port, and,
oil fumes are discharged from the frying bucket through the air exhaust port, the air inlet, the cooling flow channel, and the air outlet.

8. The air cooking device of claim 7 , wherein the frying bucket includes retaining ribs extending upward from the bottom, wherein the air exhaust port is provided on the inner side of the retaining ribs, to prevent condensed oil-water mixture in the frying bucket from flowing into the air exhaust port.

9. The air cooking device of claim 8 , wherein the air exhaust box includes an air inlet nozzle protruding upward from the upper surface of the air exhaust box, where the air inlet is arranged on the air inlet nozzle, and the air exhaust box also includes a sealing ring sleeved on the air inlet nozzle.

10. The air cooking device of claim 7 , wherein the main unit includes a receiving cavity under the cavity, wherein the air exhaust box is removably insertable into the cavity from one side of the main unit.

11. The air cooking device of claim 7 , wherein the air exhaust box is assembled to a bottom of the frying bucket.

12. The air cooking device of claim 7 , wherein the air exhaust box encloses a cavity, wherein the air exhaust box includes a retaining wall located in the cavity, and the retaining wall separates the air inlet and the air outlet.

13. The air cooking device of claim 12 , wherein:
the frying bucket is provided with multiple air exhaust ports, and the air exhaust box is provided with multiple air inlets;
the retaining wall divides the air exhaust box into an entrance area surrounding the outer side of the air exhaust box and a connection area on the inner side of the entrance area, with the multiple air inlets distributed in the entrance area;
water vapor generated from the frying bucket enters the entrance area through the multiple air inlets, then flows into the connection area in a clockwise direction, and flows in the connection area in a counterclockwise direction to the air outlet;
the air exhaust box includes an upper lid and a lower lid, the lower lid having a bottom wall and a bonding portion extending upward from the bottom wall;
the lower surface of the bonding portion forming an upward recess, and the upper surface of the bonding portion being bonded and fitted to the upper lid;
a fixing element connecting the air exhaust box to the frying bucket to detachably connect the air exhaust box to the bottom of the frying bucket, the fixing element being at least partially located in the recess of the bonding portion; and,
the outer edge of the lower lid extending upward to form the cavity so as to accommodate a certain amount of condensed water.

14. An air frying device comprising:
a main unit provided with an internal cavity, the main unit having a top wall above the cavity;
a drawer having a drawer panel and a frying bucket fixed on the back side of the drawer panel, the drawer being removably insertable into the cavity to perform air frying cooking, and having a sealing element surrounding a mouth portion of the frying bucket; and,
an upwardly pushing structure positioned in a rear portion of the cavity, which lifts the drawer upwards upon insertion into the cavity, thereby engaging the sealing element with the top wall of the cavity.

15. The air frying device of claim 14 , wherein the upwardly pushing structure includes a first supporting portion and a guiding surface extending obliquely and downwardly from the first supporting portion, to guide the frying bucket to move to abut against the first supporting portion.

16. The air frying device of claim 15 , wherein the main unit includes a second supporting portion for supporting the drawer panel.

17. The air frying device of claim 15 , wherein the frying bucket includes a guiding inclined surface, wherein during the process of pushing the frying bucket into the cavity, the guiding inclined surface moves along the guiding surface.

18. The air frying device of claim 14 , wherein:
the frying bucket includes a bottom and an air exhaust port arranged at the bottom,
the air cooking device further comprises an air exhaust box, the air exhaust box having an air inlet, an air outlet, and a cooling flow channel connecting the air inlet and the air exhaust port, and,
oil fumes are discharged from the frying bucket through the air exhaust port, the air inlet, the cooling flow channel, and the air outlet.

19. The air frying device of claim 14 , wherein the frying bucket includes a bottom and an air exhaust port arranged at the bottom, and wherein the frying bucket includes retaining ribs extending upward from the bottom, wherein the air exhaust port is provided on the inner side of the retaining ribs, to prevent condensed oil-water mixture in the frying bucket from flowing into the air exhaust port.
