Since no new grease is introduced, it is equivalent to frying by air from the viewpoint of whether or not grease is introduced. However, in the commercially available air fryer, during the frying process of the food material, the hot air path of the hot air flow in the frying basket is mainly promoted as the hot air flow is continuously blown to the surface layer of the food material, and the hot air flow often cannot penetrate through the food, so that the utilization rate of the hot air has a certain promotion space.

With the advent of kitchen appliances that correspond to various cooking modes (e.g., steaming, baking, frying, etc.), there has also been a multi-functional cooking appliance that includes air frying. Namely: the air frying and one or more cooking modes are integrated in one cooking device, so that one cooking device can realize multiple cooking modes. Such as:

In some instances, cooktop principles and the like well known to those skilled in the art have not been described in detail in order to highlight the subject matter of the invention.

Referring to fig. 1 to 4, fig. 1 is a schematic view illustrating a structure of an oven according to an embodiment of the present invention, fig. 2 is a schematic view illustrating an internal structure of an oven according to an embodiment of the present invention, fig. 3 is a schematic view illustrating an explosion of a hood assembly in an oven according to an embodiment of the present invention, and fig. 4 is a schematic view illustrating a structure of a basket in an oven according to an embodiment of the present invention. As shown in fig. 1 to 4, oven 100 mainly comprises a cooking body 1, a fan guard assembly capable of achieving circulation of hot air flow, and a fry basket 3 used during the time that the oven achieves its air-fry function. Wherein, the cooking body 1 is formed with the culinary art cavity (like the inner bag), and frying basket 3 is formed with the system cavity of frying, after the edible material that will wait to cook is placed in the system cavity of frying, places frying basket 3 in the settlement position of inner bag to accomplish the culinary art of the edible material of waiting to cook with the mode of air-fried. For example, the frying basket can be directly placed on the original grill of the oven, or a special fixing structure is configured for the frying basket, etc. A back plate 11 is arranged on one side (such as a back side) of the inner container, which is far away from an operation side (such as a side facing a user, generally referred to as a front side) of the user, a fan cover 2 is installed on the back plate, a hot air cavity is formed between the fan cover 2 and the back plate, a first air return opening 21 is arranged at a position close to the middle of the fan cover, a first air supply opening 22 is arranged outside the first air return opening 21, and an air outlet area is arranged in a mode of surrounding the air inlet area so as to more uniformly distribute air carrying heat to the surface of food materials, so that the food materials to be baked are cooked.

Wherein, a fan is arranged in the hot air chamber at a position corresponding to the first return air port 21, and the fan comprises a driving motor 23 and a fan 24. The motor rotates to drive the fan to rotate at a position facing the first air return opening 21, and the rotation of the fan can enable air in the inner container to flow through the first air return opening 21 and enter the hot air chamber. Illustratively, to ensure operational stability of the fan, the center of the fan disk of the fan substantially coincides with the center of the first return air opening 21 (i.e., the center of the fan guard). The position that corresponds to first return air inlet 21 still disposes first heating element 25 in the hot-blast cavity, and in this embodiment, first heating element is the single-deck coiled structure of class mosquito-repellent incense, and the air of inner bag is inhaled the hot-blast cavity through first return air inlet 21 by the fan after, can heat through heating coil.

In a possible embodiment, the motor 23 and the fan 24 are mounted in such a way that: in the mounted state, the driving motor 23 has three ends extending into the hot air chamber, and the three ends enclose a mounting position 231 for mounting the fan 24 and the first heating member 25, for example, each end has two slots along its length, one slot is used for forming a mounting position for mounting the fan 24 by matching with the other two ends, and the other slot is used for forming a mounting position for mounting the first heating member 25 by matching with the other two ends.

In order to ensure that the air entering the frying basket through the second air return opening can carry more heat, the invention adds a second heating unit 4 outside the bottom of the inner container, for example, the second heating unit comprises a second heating component capable of distributing heat, and the second heating component is similar to the first heating component and is also of a single-layer coiled structure similar to mosquito-repellent incense.

In the embodiment, the first air return opening 21 is substantially a disk-shaped structure formed by a plurality of grid holes, and the first air supply opening 22 includes a plurality of air supply points, for example, the air supply points are substantially strip-shaped holes. Illustratively, the fan guard includes a plate portion and a flange extending from the plate portion in a direction adjacent to the back plate 11, the back plate, the flange and the plate portion thereby forming the hot air chamber. The air supply points comprise a plurality of air supply points arranged on the turned-over edge and three groups arranged on the plate-shaped structure from top to bottom, and each group comprises a small group which is symmetrically arranged at the two sides of the first air return port 21 in a left-right mode. The number of the air supply points included in each group is gradually reduced from top to bottom. Specifically, the upper group includes groups of 8 blowing points symmetrically disposed on both sides of the first air return opening 21. The middle group includes 3 and the lower group includes 2. Obviously, the specific configuration of the first air return opening and the first air supply opening is only a specific example, and those skilled in the art can flexibly adjust the configuration according to actual needs.

Wherein the fry basket 3 is removably arranged in the liner so that the fry basket can be put into or taken out of the liner at any time. The fry basket is roughly a cylindrical structure, the side wall of the cylindrical structure is provided with a second air supply outlet 31, and the bottom wall of the cylindrical structure is provided with a second air return outlet 32. Wherein, the second supply-air outlet 31 links up with aforementioned first return air inlet, and second return air inlet 32 links up with aforementioned first supply-air outlet, specifically: the air of the frying chamber can reach the first air return opening through the second air supply opening, and at least one part of the air sent to the inner container through the first air supply opening can reach the frying chamber through the second air return opening.

In the embodiment, the second air return opening 32 is a mesh grid, and the second air supply opening 31 is an open structure substantially aligned with the first air return opening, such as a square opening substantially completely covering the first air return opening. Obviously, similar to the first air return opening and the first air supply opening, the specific configuration of the second air return opening and the second air supply opening is only a specific example, and those skilled in the art can flexibly adjust the configuration according to actual needs.

Preferably, the present invention provides a stirring member, such as a stir bar 34 in this embodiment, within the fry basket. In this way, the foodstuff can be stirred during the implementation of the air-frying. Thus avoiding the occurrence of operations: traditional air fryer is during cooking the edible material, when certain duration, need take out the fried basket and shake the edible material of waiting to cook.

Preferably, the present invention forms a shaped engagement structure 35, such as a streamline or star-like structure in the figures, on the inside of the top of the fry basket to better reflect and direct hot air reaching the top of the fry basket in a direction toward the second supply port.

Thus, under the action of the fan, the airflow enters the hot air chamber from the first air return opening 21 in the middle of the fan cover to be heated, then is distributed to the liner in a peripheral diffusion mode through each air supply point of the first air supply opening 22, then reaches the frying basket chamber through the second air return opening 32 at the bottom of the frying basket to penetrate through the food to be cooked, and then is sent to the position corresponding to the first air return opening 21 through the second air supply opening 31 at the side part of the frying basket, so that an external circulation path of the hot airflow is formed.

It can be seen that the outer circulation path of the hot air flow mainly includes the section between the second supply port and the first return port (denoted as section 1), the section between the first return port and the first supply port (denoted as section 2, similar to the original function of the oven), the section between the first supply port and the second return port (denoted as section 3), and the section between the second return port and the second supply port (denoted as section 4).

In the oven, the second air return opening and the second air supply opening are respectively arranged at the bottom and the side part of the cylindrical structure (an included angle is formed between the second air return opening and the second air supply opening), so that when hot air flows through the section 4, most of the hot air can be heated in a manner of penetrating through the food to be cooked layer by entering the food to be cooked from the bottom, and the utilization rate of the hot air is improved.

To further optimize the outer circulation path, a first constrained portion is introduced at zone 1 in this embodiment. Specifically, in the state where the fry basket is in place, the second air supply opening 31 is substantially aligned with the first air return opening 21 with a certain clearance (e.g., within about 5 cm). In order to reduce or avoid the overflow of the hot air flow caused by the gap when the hot air flow passes through the aforementioned section 1 (once the overflow occurs, the hot air flow participating in the external circulation is reduced, which affects the performance of the external circulation to some extent), in this embodiment, two baffles 33 are respectively disposed at two sides of the position corresponding to the second air blowing opening. Therefore, the hot air flow can be effectively prevented from diffusing to two sides when flowing through the section 1, on one hand, the diffusion of the hot air flow causes the reduction of the hot air flow which accurately participates in the external circulation, on the other hand, the diffusion of the hot air flow can also cause the part of the hot air flow to enter the explosion chamber through the second air return opening at the bottom together with the heated hot air flow which is sent into the inner container through the first air supply opening before being heated, and the quality of the external circulation is influenced. In addition, the setting of baffle can also block to a certain extent that the steam that first supply-air outlet sent to the inner bag flows through the second supply-air outlet and flees to the system chamber of frying, consequently can avoid the destroyed phenomenon of extrinsic cycle that leads to from this. Obviously, a pair of baffles is only an exemplary illustration of the first restriction portion, and one skilled in the art can flexibly configure the first restriction portion to meet the actual requirement.

Furthermore, although not addressed in the present embodiment, a second restriction may be added to section 3 by those skilled in the art to optimize the quality and performance of the hot gas stream during flow through section 3.

It can be seen that in the inventive oven, an increase in air frying functionality is achieved through the configuration of the fry basket. On the basis, the second air supply outlet and the second air return outlet of the frying basket are set, so that an external circulation path of hot air flow of the oven during air frying is constructed. Based on this outer circulation route, can increase the probability that the hot-blast stream pierces through the edible material of waiting to cook layer by layer, improved hot-blast utilization ratio on this basis, improved the culinary art performance of oven.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
