Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooking appliance technology, and in particular to a cooking device. Background Technology
[0002] Currently, commercially available air fryers generally use a forced convection hot air system as their core heating solution, which evenly distributes the heat generated by the heating element throughout the cooking cavity through a high-speed airflow circulation device. This technology has become a preferred solution in the field of healthy cooking due to its significant reduction in oil usage. However, existing equipment still faces the following technical bottlenecks in thermodynamic optimization:
[0003] First, due to the constraints of the thermal field distribution characteristics within the cavity, the spatial positioning of the ingredients leads to a gradient decrease in heat transfer efficiency. Specifically, the upper layer of ingredients near the heat source distributor undergoes localized carbonization due to receiving excessive radiative heat flux, while the lower layer of ingredients at the end of the airflow fails to reach the Maillard reaction threshold due to the decrease in thermal convection intensity.
[0004] Secondly, the problem of heat conduction imbalance caused by the heterogeneity of ingredients has not been effectively resolved. Differences in physical properties such as specific heat capacity and thermal conductivity among different ingredients, coupled with their diverse geometric forms (e.g., blocky, flaky, porous structures), lead to a significant thermal hysteresis effect under the same heat flux density. Typically, high-moisture ingredients delay the cooking process due to the absorption of latent heat of phase change, while low-heat-capacity ingredients reach the caramelization threshold prematurely, resulting in uncontrollable quality in the finished dish.

[0036] The cooking device 100 of this utility model is described below with reference to the accompanying drawings.
[0037] Reference Figures 1 to 3 According to an embodiment of the present utility model, a cooking device 100 includes: a housing 10, a guide fan 161, a heating element 70, and a movable element 20.
[0038] The housing 10 has at least a first food storage space 12, and the first food storage space 12 has at least a first inlet 121. A guide fan 161 is disposed inside the housing 10 and outside the first food storage space 12, and the guide fan 161 is used to generate circulating cooking air within the housing 10. A heating element 70 is disposed inside the housing 10 and outside the first food storage space 12, and the heating element 70 is used to heat the cooking air into cooking hot air; wherein the cooking hot air enters the first inlet 121 through a first channel. A movable member 20 is movably disposed in the first channel and / or the first inlet 121 to adjust the size of the air intake area of the first channel and / or the first inlet 121.
[0039] The housing 10 includes at least a first food storage space 12, which has a first inlet 121. A heating element 70 is located inside the housing 10 and outside the first food storage space 12, with the space containing the heating element 70 connected to the first inlet 121. A movable element 20 is movably disposed in the first channel and / or the first inlet 121 to adjust the size of the air intake area. A guiding fan 161 agitates the air, accelerates the flow of hot air, and guides the hot air to the first food storage space 12.
[0040] The cooking device 100 can be an air fryer, an air oven, or even a microwave oven. The heating element 70 heats the surrounding air, creating hot airflow for cooking. This hot air flows to the food storage space, heating the food within. The first inlet 121 connects to the space containing the heating element 70. The movable element 20 changes the size of the air intake area of the first inlet 121, thus adjusting the connection area between the space containing the heating element 70 and different locations in the first food storage space 12, guiding and distributing the heat.
[0041] In related technologies, air fryers are appliances that heat food using a high-speed hot air circulation system. They are widely used for healthy cooking because they do not require large amounts of oil. However, the varying distances of different ingredients from the heat source lead to differences in heating effects. For example, food in the upper layers may overheat, while food in the lower layers may be undercooked. Alternatively, significant differences in the type and shape of the food can result in varying heat absorption and conduction efficiencies, leading to some food being overcooked while others remain uncooked.
[0042] In this embodiment of the present invention, a movable component 20 is provided in the first channel and / or the first inlet 121. The movable component 20 is used to adjust the size of the air intake area, that is, to adjust the area of the air intake at different positions of the first food space 12, and to distribute the heat so that the heat in the first food space 12 is more adapted to the actual needs, thereby improving the cooking uniformity and the cooking effect.
[0043] For example, when the food is multi-layered, the heating element 70 is located above the first food space 12. The air intake area is adjusted by the movable element 20, so that more heat is generated around the lower food layer, thereby allowing the multi-layered food to be affected by an equal or approximately equal amount of heat, thus improving the uniformity of cooking.
[0044] Alternatively, the first ingredient and the second ingredient can be placed in the first ingredient space 12. Compared to the first ingredient, the second ingredient is more difficult to cook. The movable part 20 allows more heat to be generated around the second ingredient, adapting to the needs of the second ingredient, so that they can cook in the same pot at the same time, thereby improving the cooking uniformity and the cooking effect.
[0045] Specifically, the movable component 20 is set in the first channel to adjust the air intake area; or, the movable component 20 is set in the first inlet 121 to adjust the air intake area; or, the movable component 20 is set in both the first channel and the first inlet 121 to adjust the air intake area.
[0046] Specifically, there are two active items 20, or there is one active item 20.
[0047] Of course, this is not limited to the first entrance 121; there can also be a third entrance, a fourth entrance, or more.
[0048] In some specific embodiments, the cooking device 100 is an air oven, the housing 10 can form a cooking cavity, the side wall of the housing 10 is provided with a ventilation channel, and the movable part 20 is used to adjust the ventilation position or ventilation area of the ventilation channel on the side wall.
[0049] In some other specific embodiments, the cooking device 100 is an air fryer, with an inner pot or frying drum inside the shell 10. The inner pot or frying drum has ventilation channels on its side wall, and the movable part 20 is used to adjust the ventilation position or ventilation area of the ventilation channels on the side wall of the inner pot or frying drum.
[0050] In some other specific embodiments, the cooking device 100 is an air fryer, with an inner pot or frying drum inside the shell 10, and a frying basket placed inside the inner pot or frying drum. Air flows through the channel between the frying drum and the frying basket, and there are ventilation holes on the frying basket. The movable part 20 is used to adjust the ventilation position or ventilation area of the ventilation holes on the side wall.
[0051] In some other specific embodiments, the cooking device 100 is an air oven, the housing 10 has an inner wall with ventilation channels, and the movable part 20 is used to adjust the ventilation position or ventilation area of the ventilation channels on the inner wall.
[0052] According to the embodiment of the present invention, the cooking device 100 provides a movable part 20 in the first channel and / or the first inlet 121, and uses the movable part 20 to distribute heat, so that the heat in the food space is more adapted to the needs, improving the cooking uniformity and enhancing the cooking effect.
[0053] In some specific embodiments, the cooking device 100 further includes: a second food space 13, a second inlet 131 disposed in the second food space 13, cooking hot air entering the second inlet 121 through a second channel, and a movable member 20 movably disposed in the second channel and / or the second inlet 121 to adjust the size of the air intake area of the second channel and / or the second inlet 121.
[0054] The second food space 13 is different from the first food space 12. The movable component 20 is also provided in the second channel and / or the second entrance 121 to adjust the size of the air intake area of the second channel and / or the second entrance 121, thereby realizing directional cooking.
[0055] In the above solution, by setting up a second ingredient space 13 on the basis of the first ingredient space 12, more quantity and variety of ingredients can be cooked, which improves the targeting and thus enhances the uniformity of cooking.
[0056] Specifically, the first entrance 121 and the second entrance 131 can each be set with a corresponding active component 20, that is, there are two active components 131; or, the first entrance 121 and the second entrance 131 can correspond to the same active component 131, that is, one active component 131 corresponds to the two entrances, the first entrance 121 and the second entrance 131.
[0057] Reference Figures 1 to 3 The food space includes a first food space 12 and a second food space 13.
[0058] The first entrance 121 is located in the first food space 12. The second entrance 131 is located in the second food space 13.
[0059] The heating element 70 heats the surrounding air, creating a hot airflow that flows to the first food storage space 12 and the second food storage space 13, heating the food within them. A first inlet 121 connects to the space containing the heating element 70, serving as the connection point between the space containing the heating element 70 and the first food storage space 12. The area of the first inlet 121 is the connection area. A second inlet 131 also connects to the space containing the heating element 70, serving as the connection point between the space containing the heating element 70 and the second food storage space 13. The area of the second inlet 131 is the connection area. The movable element 20 changes the size of the first inlet 121 and the second inlet 131, thus adjusting the connection area between the space containing the heating element 70 and the first food storage space 12, and adjusting the connection area between the space containing the heating element 70 and the second food storage space 13, thereby distributing heat.
[0060] In this embodiment of the invention, movable parts 20 are provided in the first inlet 121 and the second inlet 131. The size of the first inlet 121 and the second inlet 131 is adjusted by the movable parts 20, that is, the connection area between the first food space 12 and the space where the heating element 70 is located is adjusted, and the connection area between the second food space 13 and the space where the heating element 70 is located is adjusted, so that the heat in the first food space 12 and the second food space 13 is more adapted to the actual needs, which can improve the cooking uniformity and improve the cooking effect.
[0061] For example, compared to the second food space 13, the first food space 12 is closer to the heating element 70. The movable element 20 makes the first inlet 121 smaller than the second inlet 131, so that more heat enters the second food space 13. This makes the food in the first food space 12 and the second food space 13 affected by the same or approximately the same amount of heat, thus improving the uniformity of cooking.
[0062] Alternatively, the first ingredient is placed in the first ingredient space 12, and the second ingredient is placed in the second ingredient space 13. Compared to the first ingredient, the second ingredient is more difficult to cook. By using the movable part 20 to make the first entrance 121 smaller than the second entrance 131, more heat enters the second ingredient space 13, thus making the second ingredient space 13 have more heat, which meets the needs of the second ingredient. They cook in the same pot at the same time, thereby improving the uniformity of cooking and improving the cooking effect.
[0063] Specifically, there are two active components 20, with corresponding active components 20 set on the first entrance 121 and the second entrance 131, or there is one active component 20, with the first entrance 121 and the second entrance 131 corresponding to the same active component 20.
[0064] Of course, this is not limited to the first entrance 121 and the second entrance 131. There can also be a third entrance, a fourth entrance, or more. Correspondingly, there can also be a third food space, a fourth food space, or more.
[0065] In the above scheme, by setting movable parts 20 in the first inlet 121 and the second inlet 131, the heat is distributed by the movable parts 20, so that the heat in the first food space 12 and the second food space 13 is more adapted to their respective needs, thereby improving the matching rate, improving the cooking uniformity of each food space, and improving the cooking effect.
[0066] Reference Figures 1 to 3 In some embodiments, the guide fan 161, the first food space 12, and the second food space 13 are arranged longitudinally in sequence within the housing 10. The housing 10 includes an inner shell 14. The first food space 12 and the second food space 13 are disposed within the inner shell 14. The inner shell 14 is provided with a first through-hole area 141 and a second through-hole area 142. The movable member 20 is movably disposed on the housing 10 in a direction toward or away from the guide fan 161 to adjust the open area of the first through-hole area 141 and the second through-hole area 142.
[0067] The movable component 20 is movably mounted on the housing 10. The movable component 20 blocks the first through hole area 141 and the second through hole area 142. The first inlet 121 is the part that connects the first through hole area 141 with the space where the heating element 70 is located. The second inlet 131 is the part that connects the second through hole area 142 with the space where the heating element 70 is located. Each movable component 20 corresponds to the first inlet 121 and the second inlet 131. The movable component 20 can change the area of the connected part, thereby changing the size of the first inlet 121 and the second inlet 131.
[0068] In the above solution, by setting a first through-hole area 141 and a second through-hole area 142 on the inner shell 14, and using the movable part 20 to cooperate with the first through-hole area 141 and the second through-hole area 142, the adjustment method is simple, the structure is simple, and the reliability is high.
[0069] Specifically, multiple through holes can be provided on the first through hole area 141, or a single larger through hole can be provided on the first through hole area 141. There is no restriction here. Similarly, multiple through holes can be provided on the second through hole area 142, or a single larger through hole can be provided on the second through hole area 142.
[0070] In some embodiments, the movable member 20 is configured as a rotating member, which is rotatably disposed in the first through-hole area 141 and the second through-hole area 142, thereby adjusting the communication area between the first through-hole area 141 and the space where the heating member 70 is located, and adjusting the communication area between the second through-hole area 142 and the space where the heating member 70 is located.
[0071] Specifically, the rotating component is installed inside the hole, and its rotation changes the connected area.
[0072] Reference Figures 1 to 3 In some embodiments, the movable plate is configured as a sliding plate adapted to move relative to the housing 10.
[0073] The movable component moves relative to the housing 10, and the movable plate blocks the first through hole area 141 and the second through hole area 142, adjusting the communication area between the first through hole area 141 and the space where the heating element 70 is located, and adjusting the communication area between the second through hole area 142 and the space where the heating element 70 is located.
[0074] In the above solution, by constructing the movable plate as a movable plate, the connection area between the first through-hole area 141 and the space where the heating element 70 is located is adjusted by the movable plate, and the connection area between the second through-hole area 142 and the space where the heating element 70 is located is adjusted. The physical structure is well coordinated, the overall reliability is higher, and the cooking device 100 works more stably.
[0075] In some embodiments, the movable plate partially blocks the first through-hole area 141 and partially blocks the second through-hole area 142.
[0076] The movable plate is a single unit, which partially blocks the first through-hole area 141 and partially blocks the second through-hole area 142.
[0077] In the above solution, by setting a movable plate to block both the first through hole area 141 and the second through hole area 142, that is, a single movable plate can simultaneously adjust the communication area between the first through hole area 141, the second through hole area 142 and the space where the heating element 70 is located, thereby reducing the number of parts and lowering the cost.
[0078] Specifically, a single movable plate can also be moved to a position that completely corresponds to the first through-hole area 141, with the second through-hole area 142 open and completely connected to the space where the heating element 70 is located; or, a single movable plate can be moved to a position that completely corresponds to the second through-hole area 142, with the first through-hole area 141 open and completely connected to the space where the heating element 70 is located.
[0079] Reference Figures 1 to 4 In some embodiments, the cooking device 100 further includes a drive assembly 30 and a control unit.
[0080] The drive assembly 30 is connected to the movable plate. The control unit is electrically connected to the drive assembly 30 to drive the movable plate to move.
[0081] The drive component 30 provides power to the moving plate, enabling it to move.
[0082] In the above scheme, by setting the drive component 30 to drive the moving plate to move, and the control component to control the drive component 30, the level of automation is improved and the heat is easily adjusted automatically.
[0083] Specifically, the drive assembly 30 can be a telescopic motor, which is connected to the moving plate and drives the moving plate to move. Alternatively, the drive assembly 30 includes a rotary motor and a gear and rack assembly, where the rotary assembly drives the gear 312 to rotate and drives the rack 311 to move.
[0084] Specifically, the control unit controls the drive component 30 in real time, changing the flow pattern of the airflow to achieve uniform cooking.
[0085] In some specific embodiments, a temperature detection element is provided inside the housing 10. The temperature detection element is electrically connected to a control element, and the temperature feedback controls the drive assembly 30, further improving the effect. Specifically, temperature detection elements are provided at the top and bottom of the food space.
[0086] Reference Figures 1 to 4 In some embodiments, the drive assembly 30 includes a transmission assembly and a drive motor 32.
[0087] The moving end of the transmission component 31 is connected to the moving plate. The output end of the drive motor 32 is connected to the transmission component 31 to drive the moving end to move.
[0088] The transmission component is connected to the moving plate, and the drive motor 32 provides power to drive the moving end of the transmission component to move, which in turn drives the moving plate.
[0089] In the above solution, the drive motor 32 is used to drive the moving plate to move by cooperating with the transmission component. The overall structure is simple, easy to operate, and makes assembly more convenient.
[0090] Specifically, the transmission component can be a gear and rack assembly, with rack 311 connected to the moving plate, or a four-bar linkage, with the moving rod of the four-bar linkage connected to the moving plate.
[0091] Reference Figure 4 , Figure 7 In some embodiments, the transmission component 31 includes a rack 311 and a drive gear 312.
[0092] The rack 311 is connected to the moving plate. The drive gear 312 meshes with the rack 311, and the output end of the drive motor 32 is connected to the drive gear 312 to drive the rack 311 to move.
[0093] Among them, the drive gear 312 meshes with the rack 311, and the drive gear 312 drives the rack 311 to move. The overall structure is stable and reliable, and the power transmission is more stable.
[0094] Reference Figure 3 , Figure 4 In some embodiments, there are multiple first through-hole areas 141, which are spaced apart along the circumferential direction of the inner shell 14. The movable plate extends along the circumferential direction and is adapted to block the multiple first through-hole areas 141. At the same time, there are multiple second through-hole areas 142, which are spaced apart along the circumferential direction of the inner shell 14. The movable plate extends along the circumferential direction and is adapted to block the multiple second through-hole areas 142.
[0095] Multiple first through-hole areas 141 are spaced apart along the circumferential direction of the inner shell 14. Hot airflow enters the first food space 12 through the multiple first through-hole areas 141. A single moving plate corresponds to multiple first through-hole areas 141 and controls the unobstructed flow of multiple first through-hole areas 141. Multiple second through-hole areas 142 are spaced apart along the circumferential direction of the inner shell 14.

[0103] Reference Figures 3 to 5 In some embodiments, the housing 10 is provided with an opening 15 that connects to the external space, the opening 15 connecting the first food space 12 and / or the second food space 13, and the movable plate includes a connecting part 21 and a plurality of sealing parts 22.
[0104] A connecting portion 21 is located on the side of the housing 10 opposite to the opening 15, and the connecting portion 21 is connected to the drive assembly 30. A plurality of sealing portions 22 are connected to the opposite sides of the connecting portion 21, and the sealing portions 22 are adapted to seal the first through-hole area 141 and / or the second through-hole area 142.
[0105] The opening 15 on the housing 10 connects to the external space for the entry and exit of food. The sealing part 22 on the moving plate corresponds to the first through hole area 141 and the second through hole area 142, sealing the first through hole area 141 and the second through hole area 142. The connecting part 21 on the moving plate connects to the drive assembly 30 to provide power.
[0106] In the above solution, by setting the connecting part 21 on the side of the housing 10 away from the opening 15 and setting the sealing part 22 on the opposite side of the connection, it is convenient to put in and take out the food.
[0107] Specifically, the first food space 12 is provided with a tray, which is adapted to enter and exit the opening 15. The connecting part 21 is located on the side opposite to the opening 15, thereby facilitating the entry and exit of the tray.
[0108] Reference Figure 5 , Figure 6 In some embodiments, the housing 10 further includes an outer shell 16, with a guide fan 161 and a fan motor 162 disposed between the outer shell 16 and the inner shell 14. The guide fan 161 is disposed in the same space as the heating element 70, and the fan motor 162 is connected to the guide fan 161 to guide the internal hot air to the first food space 12 and / or the second food space 13.
[0109] The guide fan 161 agitates the air, accelerates the flow of hot air, and guides the hot air to the first food space 12 and the second food space 13. The guide fan 161 is connected to the fan blade motor 162, which drives the guide fan 161 to rotate.
[0110] In the above scheme, by setting a guide fan 161 to disturb the air, hot air can be quickly entered into the first food space 12 and the second food space 13, thus improving efficiency.
[0111] Reference Figure 5 , Figure 6 In some embodiments, a partition plate 17 is provided between the outer shell 16 and the inner shell 14. The partition plate 17 and the inner shell 14 together define a heating space 11 for accommodating the heating element 70 and the guiding fan 161. The fan blade motor 162 is mounted on the partition plate 17 and located between the outer shell 16 and the partition plate 17. The fan blade motor 162 is also connected to a heat dissipation fan blade 163, which is located in the same space as the fan blade motor 162.
[0112] The partition plate 17 is disposed between the outer shell 16 and the inner shell 14. The fan motor 162 is fixed on the partition plate 17. The fan motor 162 and the guide fan 161 are located on both sides of the partition plate 17. The heat dissipation fan blade 163 is located on one side of the partition plate 17 along with the fan motor 162. The heat dissipation fan blade 163 disturbs the air around the fan motor 162 and cools the fan motor 162.
[0113] In the above solution, by setting up a partition plate 17, the heat dissipation fan blade 163 and the fan blade motor 162 are placed in the same space, which avoids the fan blade motor 162 and the guide fan 161 from interfering with each other, and the heat dissipation fan blade 163 is used to cool the fan blade motor 162, thereby improving the overall performance.
[0114] Reference Figure 5 , Figure 6 In some embodiments, the cooking device 100 further includes a first tray 50 and a second tray 60, the first tray 50 and the second tray 60 being arranged sequentially at intervals in a direction away from the heating element 70, the first tray 50 defining a first food space 12, and the second tray 60 defining a second food space 13.
[0115] The first tray 50 is used to carry food ingredients, and the first tray 50 and the inner wall of the shell 10 together define the first food ingredient space 12. The second tray 60 is used to carry food ingredients, and the second tray 60 and the inner wall of the shell 10 together define the second food ingredient space 13.
[0116] In the above solution, the first tray 50 and the second tray 60 are used to carry the food ingredients. The first tray 50 and the second tray 60 are placed inside the housing 10 to facilitate the loading and unloading of the food ingredients.
[0117] Specifically, the first tray 50 and the second tray 60 are arranged alternately in the direction away from the heating element 70, and the movable element 20 adjusts the size of the first inlet 121 and the second inlet 131 so that the heat in the second food space 13 is equal to or approximately equal to that in the first food space 12.
[0118] Specifically, the cooking device 100 is an air fryer, and the heating element is a heating tube. When cooking multiple layers of food in the air fryer, because the heating tube and the guide fan 161 are placed at the top of the cooking device 100, the top airflow speed is much greater than the bottom airflow. A large amount of hot air circulates at the top, causing the top layer of food to be heated more than the bottom layer. To solve the problem of uniformity, it is necessary to force the hot airflow to flow near the bottom layer of food and exchange heat with it. However, due to the large differences in resistance between different types and quantities of food, simply restricting the airflow through structure makes it difficult to ensure that all food is cooked at the same temperature in all situations. In this embodiment of the invention, by setting a movable component 20, the airflow pattern is changed in real time, thereby achieving cooking uniformity. After the airflow exits from the outlet of the guide fan 161, it enters the first food space 12 and the second food space 13 through the through holes on the side of the inner shell 14. Through holes are opened from top to bottom on the side of the inner shell 14 to allow airflow in. Figure 1 The image shows the flow field at the far-end air intake. One implementation of the duct switching mechanism is a flat plate. Figure 1 In the middle, the structure blocks the through hole on the upper side of the inner shell 14, forcing the airflow to move downwards and enter from the bottom of the second food space 13 to heat the food in the lower layer. Figure 3 The middle structure moves downwards to block the through-hole on the lower side of the cooking cavity, allowing airflow to enter the cooking cavity from the upper layer and heat the food on top. The air duct switching structure can remain in the middle position to achieve airflow distribution between the upper and lower layers. Furthermore, by placing temperature sensors at the top and bottom, the air duct status can be controlled through temperature feedback. When the upper layer temperature is lower than the lower layer temperature, air enters from the upper layer; conversely, when the lower layer temperature is lower than the upper layer temperature, air enters from the lower layer.
[0119] In some specific embodiments, the movable part 20 is disposed on the housing 10 corresponding to the second food space 13 to adjust the open area of the second through-hole area 142 to 0. That is to say, no cooking hot air enters the second food space 13, so air frying can be performed in the first food space 12, while windless cooking, such as baking and roasting, can be achieved in the second food space 13, thereby providing a variety of cooking methods and improving applicability.
