Description

Guiding type cooking equipment with air frying function

Technical Field

The invention relates to the technical field of kitchen electrical equipment, in particular to a guiding type cooking device with an air frying function.

Background

The air fryer is used as kitchen electrical equipment of new jin food class, and the working principle of the air fryer is to replace hot oil originally used for frying with hot air flow, and the hot air flow is circulated in a closed space (a frying basket), so that the food is fried with grease of the food. 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, deep frying, etc.) on the market, 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:

chinese utility model patent (CN213786957U) discloses a multifunctional oven, and specifically discloses the following: the oven door is hinged on the oven shell, a baking cavity consisting of a U-shaped liner, a bottom back plate and the oven door is arranged in the oven shell, the U-shaped liner and the bottom back plate form an oven outer cavity, heating pipes are respectively arranged on the inner top surface of the U-shaped liner and the bottom surface of the bottom back plate of the baking cavity, a top shaded pole motor is arranged at the top of the U-shaped liner, it is used for radiating upside fan including one end oven outer cavity intercommunication, one end and roast chamber intercommunication make the downside fan that the air flows when the air is fried, another vent of upside fan and downside fan sets up on the rear panel of end back plate, it is equipped with detachable air and fries the dish to roast intracavity, the gridion, fry in shallow oil the dish, four sides of oven shell are equipped with a plurality of shell through-holes, be equipped with on the oven shell to oven outer cavity, upside fan air supply realizes radiating outer cavity forced draught blower, it has realized that an oven multiple use function and oven outer cavity have strong heat dissipation and has fallen wet function.

When food needs to be fried by air, the heating pipe on the inner top surface of the U-shaped liner of the baking cavity works, meanwhile, the top shaded pole motor above the heating pipe supplies air to the baking cavity to drive the air in the baking cavity to flow, so that the thermal efficiency of the baking cavity is balanced, and the flowing air flows into the air channel of the lower side fan from the lower part of the top shaded pole motor and then is discharged. It can be seen that the multifunctional oven of this document can achieve three cooking functions of baking, air-frying and frying. However, when the cooking function of air frying is completed, the hot air path of the hot air flow in the frying basket is basically the same as that of the air frying pan with single function, so that the utilization rate of the hot air is also improved to a certain extent similarly to the condition of the air frying pan with single function.

Accordingly, there is a need in the art for a new solution to the above problems.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Furthermore, while numerous specific details are set forth in the following description in order to provide a better understanding of the invention, it will be apparent to those skilled in the art that the invention may be practiced without some of these specific details. In some instances, oven principles and the like, which are well known to those skilled in the art, have not been described in detail in order to not unnecessarily obscure the present 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 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 fry 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 a cooking chamber (such as a liner), the frying basket 3 is formed with a frying chamber, and after the food material to be cooked is placed in the frying chamber, the frying basket 3 is placed at the set position of the liner, so that the cooking of the food material to be cooked is completed in an air-frying mode. 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 the operation side is a side facing a user, and generally referred to as a front side), 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, the fan cover is provided with a first air return opening 21 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 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). A heating coil 25 is further arranged in the hot air chamber at a position corresponding to the first air return opening 21, and air in the inner container can be heated through the heating coil after being sucked into the hot air chamber through the first air return opening 21 by the fan.

In the embodiment, the first air return opening 21 is substantially a circular through hole, and the first air supply opening 22 includes a plurality of air supply points, for example, the air supply points substantially include two sets of strip-shaped holes located at two sides of the first air return opening 21, and each set of strip-shaped holes includes three holes arranged from top to bottom. 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, flange and plate portion thereby forming the aforementioned hot air chamber. The air supply point is arranged on the back plate. 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 requirements, such as increasing the number of air supply points, changing the first air return opening into a mesh grid, and the like.

Wherein the frying basket 3 is arranged in the inner container in a removable way, so that the frying basket can be put into or taken out of the inner container 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 conveyed 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 substantially mesh grid, and the second air supply opening 31 is an open structure substantially aligned with the first air return opening, such as a substantially square opening 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.

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 inner container 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 outer circulation path of the hot airflow is formed.

It can be seen that the outer circulation path of the hot air flow mainly includes a section between the second supply port and the first return port (referred to as section 1), a section between the first return port and the first supply port (referred to as section 2), a section between the first supply port and the second return port (referred to as section 3), and a section between the second return port and the second supply port (referred to 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, the present invention introduces a constraining section comprising a first constraining portion configured for zone 3 and a second constraining portion configured for zone 1. In one possible embodiment, the first and second constrained portions are configured as follows:

1) the first guide portion corresponding to the section 3 is of the specific form: the first guide portion is disposed for a plurality of blowing points of the first blowing port. The first guide portion comprises a first main tube 41 and a second main tube 42 of a bent structure, the vertical portion of which is the upstream portion provided with a nozzle at a position corresponding to each blowing point, according to the orientation in fig. 2. The transverse part is a downstream part, the downstream part further comprises a plurality of parallel branch pipes 43 which are arranged between the two main pipes and distributed along the axial direction of the main pipes, each branch pipe is provided with a communicating pipe section 431 along the axial direction of the branch pipe, the pipe openings of the communicating pipe sections are communicating openings, and each communicating opening is aligned with the second air return opening, so that air sent out through the corresponding communicating opening can be guided to the corresponding position of the second air return opening. As in the present embodiment, the air from the first supply port can be delivered to the communication hole in the bottom of the basket in a multi-point delivery form by the cooperation of the plurality of branch pipes and the plurality of communication ports on each branch pipe.

It is obvious that the above-mentioned construction form is only an exemplary description of the first restriction portion corresponding to the section 3, and those skilled in the art can flexibly construct the first restriction portion according to actual needs. Such as may be: changing two pipelines with a plurality of nozzles of the upstream part into two chambers which are separated from the left and the right and cover corresponding areas and are communicated with the downstream part; and the like.

2) The second guide portion corresponding to section 1 is of the specific form: with the fry basket in place, the second supply port 31 is generally aligned with the first return air port 21 with a clearance (e.g., within approximately 5 cm). In order to reduce or avoid the overflow of the hot air flow caused by the existence of the gap when the hot air flow flows through the aforementioned section 1 (once the hot air flow participating in the external circulation is reduced, which affects the performance of the external circulation to a certain extent), in the present embodiment, a cylindrical structure 33 which is closed in the whole circumferential direction is provided at a position corresponding to the second air blowing opening, and the macroscopic shape of the cross section of the cylindrical structure 33 is a square, square microstructure which completely surrounds the first air blowing opening, and is a wavy line. Therefore, the hot air flow can be effectively prevented from diffusing to the periphery when flowing through the section 1, the diffusion of the hot air flow can not only reduce the hot air flow which accurately participates in the external circulation, but also can cause that the part of the hot air flow enters the frying 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 arrangement of the cylindrical structure 33 can also prevent the hot air sent to the inner container from flowing back to the frying chamber through the second air supply opening by the first air supply opening to a certain extent, so that the phenomenon that the external circulation is damaged due to the reverse flowing can be avoided.

It is obvious that the above-mentioned cylindrical structure is only an exemplary description of the second constraint part corresponding to the segment 1, and those skilled in the art can flexibly construct the second constraint part according to actual needs. Such as one baffle or a combination of several baffles, which may not be all circumferentially distributed, etc.

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 such as: traditional air fryer is when cooking the edible material, waits for a certain time, needs take out the fried basket and rocks the edible material of waiting to cook.

Preferably, the present invention forms engagement structure 35, which may be streamlined or star-like in the figures, in a shape 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 air supply port.

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 the external circulation path, the probability that hot air flows through the food materials to be cooked layer by layer can be increased, the hot air utilization rate is improved on the basis, and the cooking performance of the oven is improved. And, by introducing the constraining section (especially the second constraining section introduced therein) in the section of the external circulation path, it is possible to better constrain the hot gas flow to complete the external circulation on the flow path in a predetermined manner.

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.
