Description

Shaking-free cooking equipment with air frying function

Technical Field

The invention relates to the technical field of kitchen electrical equipment, in particular to shaking-free cooking equipment 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 that hot air flow replaces hot oil which is originally used for frying, the hot air flow circulates in a closed space (a frying basket), and grease of food materials is used for frying the food materials. 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:

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 of the baking cavity and the bottom surface of the bottom back plate, 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 the 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, and 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 heat efficiency of the baking cavity is balanced, and the flowing air flows into the air channel of the lower side fan from the lower side of the top shaded pole motor and then is discharged. It can be seen that the multifunctional oven of this document can realize 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.

Technical scheme

In view of the above, the present invention provides a shaking-free cooking apparatus with an air-frying function, comprising: 1) a cooking body formed with a cooking chamber; 2) a fan guard assembly capable of heating air and including a first return air opening to allow air to flow out of the cooking chamber and a first supply air opening to allow air to flow into the cooking chamber; and 3) a fry basket removably disposed to the cooking chamber, the fry basket forming a fry chamber for holding food material to be cooked; the frying basket is provided with a second air supply opening corresponding to the first air return opening, so that the air in the frying chamber can reach the first air return opening through the second air supply opening; wherein the fry basket has a second air return opening corresponding to the first air supply opening so that at least a portion of the air supplied through the first air supply opening reaches the fry chamber through the second air return opening; the cooking apparatus further includes: an interference portion movably disposed in the fry basket to: based on the activity, at least a portion of the food material contained within the fry basket to be cooked is repositioned.

With this arrangement, the air can be fried in an externally circulating flow.

Specifically, the second air supply opening and the second air return opening, which correspond to the first air supply opening and the first air supply opening provided in the basket, define a flow path of hot air flow of the frying chamber → the second air supply opening → the first air return opening → the first air supply opening → the second air return opening → the frying chamber, and therefore, the food to be cooked can be heated more favorably.

It can be understood that, those skilled in the art can flexibly set the form and number of the second air supply openings and the corresponding form of the second air return openings according to actual requirements. Such as may be: the frying basket is provided with two separated second air supply outlets which are directly aligned with the first air return opening; the frying basket is provided with two second air supply openings, one second air supply opening is aligned with the first air return opening, the frying basket is provided with two separated second air supply openings, and the other second air supply opening is not aligned with the first air return opening; the fry basket has two separate second air outlets, one of which is directly aligned with the first air return; the other second supply port is switchable between alignment and misalignment with the first return air port; and the like.

It can be understood that, a person skilled in the art can flexibly set the corresponding form of the second return air inlet and the first supply air outlet according to actual requirements. Such as may be: in the hot air flow sent out by the first air supply outlet, if the hot air flow needs to return to the frying cavity again, the hot air flow can only return through the second air return outlet; the hot air flow sent out by the first air supply outlet can return through a second air return opening if the hot air flow needs to return to the frying cavity again, and can also return through the second air supply outlet (which can be sent back) or other original/newly-added structures; the second air return openings comprise a plurality of air return openings, and all hot air flow sent out by the first air supply opening is distributed to the second air return openings; and the like.

In addition, it can be understood that the structural form, the number and the arrangement position of the second air return openings in the frying basket can be flexibly arranged by a person skilled in the art according to actual requirements. Such as may be: setting the arrangement position of the second air outlet by taking the hot air flow as a target to penetrate through the food to be cooked; the second air return openings comprise a plurality of air return openings, and hot air flow can be tried to penetrate through the local or the whole of the food to be cooked in an expected mode through the cooperation of the air return openings at a plurality of positions; and the like.

In addition, the interference part can be arranged to realize the function of free-shaking air explosion.

In particular, during the air-frying of the food material to be cooked by the fry basket, there is no need to remove the fry basket for shaking as is required with conventional air fryers. Therefore, on the premise of ensuring the cooking effect, the operation that an operator needs to take out the frying basket and shake the frying basket is avoided.

It can be understood that the specific structural form, number, moving mode relative to the frying basket, time/duration of food material interference, etc. of the interference part can be determined by those skilled in the art according to actual needs. Exemplarily, the following steps are carried out: the interference part is a simple rod-shaped structure, and during cooking, the rod-shaped structure continuously rotates at the position approximately in the middle of the frying basket, so that the food materials to be cooked close to the middle are loosened or moved slightly, and all the food materials to be cooked are driven to be loosened or moved slightly approximately in position; the interference portion comprises a combination of a plurality of structures, some or all of which can be activated during cooking, so that the food material to be cooked in the corresponding area is loosened/moved to a desired extent based on the activation; and the like.

In a possible embodiment, the interference portion includes a first portion, and at least the first portion is movably disposed in the fry basket.

By this arrangement, a specific form of the interference portion is given.

It will be appreciated that the structural form of the first part may be determined by those skilled in the art according to actual needs, and may include, but is not limited to, a rod-like structure, a shovel-like structure, and a fork-like structure.

With regard to the above-mentioned sloshing-free cooking apparatus having an air-frying function, in a possible embodiment, the interference portion includes a second portion to which the first portion is movably provided.

With this arrangement, a specific configuration of the interference portion is given.

It is understood that the structural form of the second part can be determined by those skilled in the art according to actual needs, such as but not limited to a shell-like structure and a block-like structure. On this basis, it should be noted that the second portion and the fry basket may be integrally formed, fixedly connected, or integrally formed. Exemplarily, the following steps are carried out: the second part is fixed on a cylindrical structure of the frying basket, the first part is a rod-shaped structure which is partially penetrated in the cylindrical structure, and the rod-shaped structure can freely rotate in the cylindrical structure; and the like.

With the above-described sloshing-free cooking apparatus having an air-frying function, in one possible embodiment, the second part has a receiving space, and at least a part of the first part can be switched between a state of being in/out of the receiving space.

With such an arrangement, it is possible to avoid unnecessary interference of the interference portion with the material to be cooked.

In particular, it is theoretically not necessary that the food material to be cooked continuously undergoes a change in position such as loosening/moving/shaking during cooking in the air-fry mode. Therefore, a state in which at least a part of the first portion is in the housing space may be defined as a non-operating state, and a state in which at least a part of the first portion is not in the housing space may be defined as an operating state. Therefore, only the switching logic of the working state and the non-working state is needed to be set, and the cooking effect can be guaranteed on the premise of avoiding the operation of shaking after the frying basket is taken out.

It can be understood that, a person skilled in the art can flexibly set the configuration of the accommodating space, the specific form of the accommodating space, the degree of the accommodating space accommodating the first part, the switching form of the first part between the non-working state and the working state, and the like according to actual requirements. Exemplarily, the following steps are carried out: the first part is a shell-shaped structure, and the shell-shaped structure forms an accommodating space capable of completely accommodating the first part; the first part is formed by buckling two parts, and under the condition that the first part is required to be in a non-working state, the two parts are buckled to change into a state that the first part is accommodated in the first part, so that the food to be cooked cannot be changed in position due to the action of the first part when the first part acts; and the like.

With the above-described sloshing-free cooking apparatus having an air-frying function, in one possible embodiment, the second part is movable in a telescopic manner with respect to the first part and is thus in/out of a state of the storage space.

By such an arrangement, a specific configuration of the first portion and the second portion is given.

In a possible embodiment, the first part is rotatably arranged on the frying basket.

By this arrangement, a particular form of the first portion being movable relative to the fry basket is provided.

It can be understood that a person skilled in the art can set a specific rotation mode, a rotation time, a rotation force, etc. according to actual needs. Taking the rotation mode as an example, the following modes can be adopted: spinning, e.g., about one of the axes of the first portion itself (e.g., an axis coincident with the axis of the basket); revolution, if one of the axes of the revolution is taken as a generatrix, the revolution rotates around the axis of the frying basket; other rotation means than 360 rotation, such as oscillating back and forth within 120 °; and the like.

In a possible embodiment, the first air return opening is disposed at a position of the cooking chamber away from the operator, the second air supply opening is disposed at a position facing the first air return opening, and the second air return opening is disposed at a position of the fry basket near the bottom area.

With this arrangement, a specific relative position of the second supply port and the second return port is given.

Specifically, the hot air flow circulates in the reentry portion of the external circulation path (i.e., the aforementioned second supply opening-basket-second return opening portion), and the included angle between the second supply opening and the second return opening is about 0 ° if the second supply opening and the second return opening are substantially at the same position (e.g., similar to the internal circulation mentioned in the background art), in which case the hot air flow is likely to circulate in an easier way of directly returning to the surface of the food. The turning arrangement can limit the circulation mode of the hot air flow to a certain extent, for example, at least the length of the path is increased or the large conversion of the path is ensured to be a necessary event, so that the possibility that the hot air flow penetrates through the food to be cooked when passing through the turning road section is increased.

In one possible embodiment, the following constraints may be added:

a first restriction portion is provided between the second supply port and the first return port so as to: at least a part of the air sent out through the second air blowing port is guided to the first air return port. A second constraint part is arranged between the first air supply outlet and the second air return inlet so as to: at least a part of the air sent out through the first air blowing port can be guided to the second air return port.

By such an arrangement, the path of the external circulation can be configured more favorably.

It is understood that those skilled in the art can flexibly determine the specific arrangement of the first/second restriction parts on the cooking apparatus according to actual needs, etc. Such as may be: is an independent structure and has a single connection relation; is a structure fixedly connected with the existing structure or integrally formed; and the like.

It should be noted that the primary function of the first/second constraint part is to adjust the path of the hot gas flow at the corresponding position according to the formulated constraint target in a manner suitable for the constraint target. On the premise that the functions can be realized, those skilled in the art can flexibly determine the structural form, the number, the arrangement position and the like of the first constraint part according to actual needs, for example, the structural form, the number, the arrangement position and the like may be as follows: the first restriction portion includes a baffle plate that blocks only the air of the local area corresponding to the baffle plate to change a flow path of the air of the local area; the shielding area and the shielding direction (such as the setting position, the inclination degree and the like of the baffle) of each baffle can be the same or different; and the like.

It is obvious that the baffle is only a simplest structure form only serving as an example, and a person skilled in the art can change the baffle into any other regular structure, combination of regular structures, special-shaped structure and the like according to actual needs. In addition, the structure, number, arrangement position, arrangement mode on the cooking device, and the like of the restricting parts may be set by those skilled in the art according to actual requirements, such as only one of the first restricting part and the second restricting part.

With regard to the above-mentioned sloshing-free cooking apparatus having an air-frying function, in a possible embodiment, the first air blowing opening includes a plurality of air blowing openings, and the second restriction portion is capable of changing an air blowing direction of the plurality of air blowing openings.

With this arrangement, a particular form of the second restriction portion is given.

Such as may be: and baffles corresponding to the first air supply outlets are arranged aiming at some first air supply outlets far away from the second air return inlet, and air supply of the corresponding first air supply outlets to the direction close to the second air return inlet is guided and promoted through rotation of the baffles.

It is obvious that the rotatable baffle corresponding to the first supply-air outlet is only a simple form as an example, and those skilled in the art can change it into other forms according to actual needs, for example, one second restriction portion may be provided for a plurality of first supply-air outlets, or a second restriction portion may be provided for a second return air outlet, etc.

For the above-mentioned sloshing-free cooking apparatus with air-frying function, in one possible embodiment, the fan guard assembly includes: a fan guard disposed within the cooking chamber; wherein the fan guard is provided with a heating member and a fan at a side remote from an operator and has a hot air chamber so as to: under the action of the fan, air in the frying chamber reaches the hot air chamber through the first air return opening, is heated by the heating member and then is guided to the first air supply opening.

By means of the arrangement, a specific structure form of the fan cover assembly is given.

For the shaking-free cooking device with air-frying function, in one possible embodiment, the cooking body comprises a back plate, and the fan cover and the back plate form the hot air chamber.

By means of this arrangement, a specific design of the hot air chamber is given.

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 5, fig. 1 illustrates a structural view of an oven according to an embodiment of the present invention, fig. 2 illustrates an internal structural view of an oven according to an embodiment of the present invention, fig. 3 illustrates a structural view of a fry basket in an oven according to an embodiment of the present invention, fig. 4 illustrates a structural view of an interference part in an oven according to an embodiment of the present invention, and fig. 5 illustrates a structural view of a hood assembly in an oven according to an embodiment of the present invention. As shown in fig. 1 to 5, 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). A heating coil 25 is also arranged in the hot air chamber at a position corresponding to the first return air inlet 21, and the air in the inner container can be heated by the heating coil after being sucked into the hot air chamber through the first return air inlet 21 by the fan.

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.

In the invention, an interference part is arranged in the frying basket, and the main functions of the interference part are as follows: during the cooking of the food material to be cooked by means of the fry basket in air-frying, the food material to be cooked can be caused to undergo a positional change in the form of loosening/moving/shaking or the like by means of the interference portion, and thus, the operation of "the operator needs to take out and shake the fry basket during air-frying" can be omitted.

In a possible embodiment, the interference part 4 comprises a rotating shaft 41 and a plurality of stirring wires 42 arranged at the lower end of the rotating shaft and distributed along the circumferential direction of the rotating shaft, wherein the macro structure of the stirring wires 42 is an L-shaped structure, specifically, the stirring wires 42 comprise a transverse part extending outwards along the circumferential direction of the rotating shaft and a vertical part extending outwards along the axial direction of the rotating shaft along the outer side of the transverse part and forming a substantially cage-shaped structure. The microstructure of the stirring wire 42 is a non-straight structure, which can promote better contact between the stirring wire and the food material to be cooked. Thus, when the rotating shaft rotates relative to the frying basket, the stirring wire can be driven to rotate, and the rotation of the stirring wire can cause the food materials contacted with the stirring wire to loosen/move/shake and the like.

Obviously, the above form is only a specific form of the interference portion, and those skilled in the art can flexibly change the interference portion according to actual situations, on the premise that the intended function can be achieved. Such as may be: changing the stirring wire into a sheet structure, changing the cage shape into a cone structure and the like; adding a second part, wherein the first part can be accommodated into an accommodating space formed by the second part in a non-working state; and the like.

Preferably, the present invention forms a shaped engagement structure 34, such as a streamline or starlike structure, 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.
