Description

Technical Field

[0001] The utility model relates to the field of air fryers, in particular to an air fryer with high cooking efficiency. Background Art

[0002] With the improvement of people's living standards, the oil-free cooking method of air fryers has become more and more popular. However, among the existing air fryers, most air fryers have a single heating tube structure, that is, there is only one heating tube, which has low cooking efficiency and poor user experience. To meet user needs, a type of air fryer with dual heating components has appeared on the market. The heating components of this type of air fryer are usually arranged at the top and bottom of the cooking cavity respectively, which can heat the upper and lower surfaces of the food in the cooking cavity at the same time, effectively improving cooking efficiency. The heating component arranged at the bottom of the cooking cavity of this type of air fryer is usually a heating plate, and a downwardly concave heating groove is provided at the bottom of the cooking cavity. The heating plate is arranged in the heating groove, and a hot air gap is provided between the heating plate and the heating groove. Such an arrangement can achieve direct heating of the food in the cooking cavity while heating the air in the cooking cavity, effectively improving heating efficiency. However, since the heating component at the top of the cooking cavity will generate a circulating heat flow, this circulating heat flow can easily cause the temperature in the heating groove to be too high after entering the heating groove, thereby causing the temperature rise of the base of the air fryer to be too high, poor safety and stability in use, and poor user experience. Utility Model Content

[0003] The present application provides an air fryer with high cooking efficiency to solve the technical problems of existing air fryers in which the circulating heat flow entering the heating tank easily causes the temperature in the heating tank to be too high, thereby damaging the heating plate, and having poor safety and stability in use, resulting in a poor user experience.

[0004] In order to solve the above technical problems, the utility model provides an air fryer with high cooking efficiency, comprising a body, a cooking cavity arranged in the body, and a hot air circulation system connected to the cooking cavity, the hot air circulation system comprising a heat circulation fan and a first heating component, a frying basket with a top opening detachably provided in the cooking cavity, the top opening of the frying basket being connected to the cooking cavity; a mounting groove corresponding to the bottom wall of the frying basket and with a top opening is provided at the bottom of the cooking cavity, an annular sealing member is provided around the top opening of the mounting groove, a second heating component is provided in the mounting groove, the second heating component comprises a second heating tube and an upper cover arranged above the second heating tube and matching the top opening of the mounting groove, the peripheral edge of the upper cover being suitable for sealing with the top opening of the mounting groove through the sealing member. By arranging the first heating component and the second heating component in the body to heat the food in the cooking cavity, the cooking efficiency and cooking effect can be effectively improved; at the same time, the sealing member is used to seal the top cover with the top opening of the mounting groove, thereby preventing the circulating heat flow in the cooking cavity from entering the mounting groove and causing the temperature in the mounting groove to be too high, thereby causing the temperature of the body base to rise too high, thereby effectively improving the performance stability and safety of the air fryer.

[0005] In an optional embodiment, a sealing groove is provided around the top opening of the mounting slot, and the sealing member is disposed within the sealing groove. The sealing groove is adapted to position and / or limit the sealing member. Positioning and / or limiting the sealing member through the sealing groove not only effectively reduces the difficulty of installing the sealing member, but also effectively improves the sealing stability between the upper cover and the top opening of the mounting slot, and the performance stability of the air fryer, thereby enhancing the user experience.

[0006] In an optional embodiment, the upper cover is suitably made of a high-temperature resistant material with good thermal conductivity. Using this material not only reduces the impact of the high temperature generated by the second heating tube on the upper cover itself, effectively ensuring the performance stability of the upper cover, but also better directs the heat generated by the second heating tube into the cooking cavity, thereby heating the food therein and effectively improving cooking efficiency.

[0007] In an optional embodiment, a first support structure extending upward is provided at the bottom of the mounting slot, and the second heating assembly is adapted to be suspended within the mounting slot via the first support structure. Suspending the second heating assembly within the mounting slot prevents heat accumulation at the bottom of the second heating assembly, which could lead to excessive temperature rise at the base of the air fryer, thereby effectively ensuring the performance stability of the second heating assembly and the safety of the air fryer.

[0008] In an optional embodiment, the bottom of the cooking cavity is a lower base plate that constitutes at least a portion of the cooking cavity, the mounting slot is formed by a downward depression of the lower base plate, a lower mechanism is disposed below the lower base plate, and a first insulating chamber is formed between the lower mechanism and the lower base plate. Providing the first insulating chamber between the lower mechanism and the lower base plate not only reduces the outward transmission of high temperatures within the cooking cavity and the mounting slot, thereby reducing the impact on the performance of the lower mechanism, thereby effectively improving the performance stability of the lower mechanism, but also reduces the risk of localized overheating of the air fryer body caused by the outward transmission of high temperatures within the cooking cavity and the mounting slot, thereby reducing the risk of burns to the user, thereby effectively improving the safety and performance stability of the air fryer.

[0009] In an optional embodiment, a heat dissipation duct connected to the atmosphere is provided within the body, and a heat dissipation component for generating a heat dissipation cold flow is provided within the heat dissipation duct; a second heat-insulating cavity is adapted to be formed between the lower core and the body shell, and the second heat-insulating cavity is connected to the heat dissipation duct. By providing the second heat-insulating cavity between the lower core and the body shell, and connecting the second heat-insulating cavity to the heat dissipation duct, not only is the risk of high temperatures within the cooking cavity and the mounting slot being transferred outward, resulting in localized overheating of the body and thus causing burns to the user, reduced, the heat dissipation of the lower core by the heat dissipation cold flow within the heat dissipation duct can be achieved, thereby ensuring the performance stability of the lower core and further reducing the risk of high temperatures within the cooking cavity and the mounting slot being transferred outward, effectively improving the performance stability and safety of the air fryer.

[0010] In an optional embodiment, a second support structure extending vertically between the lower base and the lower mechanism is provided, with the upper and lower portions of the second support structure abutting the lower base and the lower mechanism, respectively. Providing the second support structure between the lower mechanism and the lower base to support the lower base ensures structural stability of the lower base, effectively improving the performance stability of the air fryer.

[0011] In an optional embodiment, the lower bottom plate is suitably made of a high-temperature resistant material. By using a high-temperature resistant material to make the lower bottom plate, the impact of high temperatures in the cooking cavity and the mounting slot on the lower bottom plate can be reduced, effectively ensuring the performance stability of the lower bottom plate.

[0012] In an optional embodiment, the top of the upper cover is adapted to be flush with the plane of the top opening of the mounting slot. This arrangement not only facilitates removal and installation of the fryer basket but also conceals the second heating assembly, thereby enhancing the overall aesthetics of the appliance.

[0013] In an optional embodiment, the bottom of the cooking cavity is provided with a plurality of upwardly extending protrusions surrounding the top opening of the mounting slot, and the frying basket is adapted to be suspended within the cooking cavity via these protrusions. By suspending the frying basket within the cooking cavity via these protrusions, a hot air gap is formed between the bottom of the frying basket and the bottom wall of the cooking cavity, through which heat flow can pass. When the circulating heat flow generated by the first heating component passes through this hot air gap, it is reheated by the second heating component, thereby compensating for heat loss caused by the circulating heat flow during the cooking process, thereby effectively improving cooking efficiency.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The present application can effectively improve cooking efficiency and cooking effects by arranging the first heating component and the second heating component in the body to heat the food in the cooking cavity; at the same time, the sealing member is used to seal the top cover with the top opening of the mounting groove, thereby preventing the circulating heat flow in the cooking cavity from entering the mounting groove and causing the temperature in the mounting groove to be too high, thereby causing the temperature of the body base to rise too high, thereby effectively improving the performance stability and safety of the air fryer.

The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0020] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0021] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0022] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this utility model.

[0025] Attachment Figure 1 To the attached Figure 3 As shown, this is a schematic diagram of an air fryer with high cooking efficiency provided by the present invention. The air fryer includes a body 10, an open cooking cavity 11 provided on the inner side of the body 10, and a hot air circulation system 20 connected to the cooking cavity 11. The cooking cavity 11 is suitable for placing food to be cooked. The hot air circulation system 20 is suitable for generating a circulating heat flow and passing it into the cooking cavity 11 to heat the food in the cooking cavity 11.

[0026] like Figure 1As shown, in an optional embodiment, the hot air circulation system 20 includes a first heating component 21, a second heating component 22 and a heat circulation fan 23 arranged above the first heating component 21, the first heating component 21 and the heat circulation fan 23 are arranged at the top of the cooking cavity 11, the first heating component 21 is suitable for heating the air in the cooking cavity 11, and the heat circulation fan 23 is suitable for driving the heated hot air to circulate to form a circulating heat flow; a frying basket 30 with a top opening is detachably provided in the cooking cavity 11 through a side opening, and the top opening of the frying basket 30 at least partially corresponds to the first heating component 21; a mounting groove 12 corresponding to the bottom wall of the frying basket 30 and with a top opening is provided at the bottom of the cooking cavity 11, and the second heating component 22 is arranged in the mounting groove 12, and the second heating component 22 is suitable for heat transfer cooperation with the bottom wall of the frying basket 30. By arranging the first heating component 21 and the heat circulation fan 23 at the top of the cooking cavity 11, and arranging the second heating component 22 in the mounting groove 12 at the bottom of the cooking cavity 11, the first heating component 11 and the second heating component 22 can cooperate with each other to heat the upper and lower surfaces of the food in the cooking cavity 11 at the same time, effectively improving the cooking efficiency and cooking effect. In addition, in another optional embodiment, the hot air circulation system 20 includes a first heating component 21, a second heating component 22 and a heat circulation fan 23 respectively arranged in the cooking cavity 11, a frying basket 30 with a top opening detachably provided in the cooking cavity 11 through a side opening, and the top opening of the frying basket 30 is connected to the cooking cavity 11; a heating cavity is provided on the outside of the cooking cavity 11, and the first heating component 21 and the heat circulation fan 23 are provided in the heating cavity, and a fan 23 is provided on the top of the cooking cavity 11 to connect the heating cavity and the cooking cavity. The air inlet of the cooking chamber 11 is adapted to be disposed toward the top opening of the frying basket 30. A return air port is provided in the middle portion of the side wall of the cooking chamber 11, communicating with the heating chamber and corresponding to the first heating assembly 21. Hot air holes are provided on the side wall of the frying basket 30, at least partially corresponding to the return air port. The circulating heat generated by the first heating assembly 21 is adapted to enter the frying basket 30 through the air inlet and the top opening of the frying basket 30 to cook food, and then flow back from the hot air holes through the return air port to the hot air chamber. The air fryer can also achieve the aforementioned effects by positioning the first heating assembly 21 on the side of the cooking chamber 11, effectively improving the cooking efficiency and quality of the air fryer.

[0027] like Figures 1 to 3As shown, in an optional embodiment, an annular seal 40 is provided around the top opening of the mounting slot 12. The seal 40 is preferably made of an elastic, high-temperature-resistant material such as rubber or silicone. The second heating assembly 22 includes a second heating tube 221 and an upper cover 222 disposed above the second heating tube 221 and matching the top opening of the mounting slot 12. The periphery of the upper cover 222 is adapted to be sealed with the top opening of the mounting slot 12 via the seal 40. The seal 40 ensures that the top cover 222 is sealed with the top opening of the mounting slot 12, thereby preventing the circulating heat flow within the cooking cavity 11 from entering the mounting slot 12, causing the temperature within the mounting slot 12 to overheat, thereby causing the base of the machine body 10 to overheat, thereby effectively improving the performance stability and safety of the air fryer.

[0028] like Figure 2 and Figure 3 As shown, in an optional embodiment, a sealing groove 121 is provided around the top opening of the mounting groove 12, and the sealing member 40 is adapted to be disposed in the sealing groove 121. The sealing groove 121 is adapted to position the sealing member 40 during installation. Positioning the sealing member 40 through the sealing groove 121 can effectively reduce the difficulty of installing the sealing member 40. At the same time, the sealing groove 121 is also adapted to limit the sealing member 40. Limiting the sealing member 40 through the sealing groove 121 can reduce the possibility of misalignment or deformation of the sealing member 40 when the upper cover 222 is connected to the top opening of the mounting groove 12, thereby reducing the possibility of poor sealing due to misalignment or deformation. This effectively improves the sealing stability between the upper cover 222 and the top opening of the mounting groove 12 and the performance stability of the air fryer, thereby improving the user experience.

[0029] In an optional embodiment, the upper cover 222 is preferably made of a high-temperature resistant material with good thermal conductivity, such as stainless steel or a copper-iron alloy. Using such a material not only reduces the impact of the high temperature generated by the second heating tubes 221 on the upper cover 222 itself, effectively ensuring the performance stability of the upper cover 222, but also better directs the heat generated by the second heating tubes 221 into the cooking cavity 11, thereby heating the food therein and effectively improving cooking efficiency.

[0030] like Figure 3As shown, in an optional embodiment, a first support structure 50 extending upward is provided at the bottom of the mounting slot 12. The first support structure 50 includes a plurality of vertically extending first support rods. The second heating assembly 22 is adapted to be suspended within the mounting slot 12 via the plurality of first support rods. By suspending the second heating assembly 20 within the mounting slot 12, heat accumulation at the bottom of the second heating assembly 22, which could cause an excessive temperature rise at the base of the machine body 10, can be avoided. This effectively ensures the performance stability of the second heating assembly 22 and the safety of the air fryer.

[0031] like Figure 2 and Figure 3 As shown, the bottom of the cooking cavity 11 is a lower base plate 13 that constitutes at least a portion of the cooking cavity 11. The mounting groove 12 is formed by a downward depression of the lower base plate 13. A lower mechanism 14 is provided below the lower base plate 13, and a first heat-insulating cavity 15 is formed between the lower mechanism 14 and the lower base plate 13. Providing the first heat-insulating cavity 15 between the lower mechanism 14 and the lower base plate 13 not only reduces the outward transmission of high temperatures within the cooking cavity 11 and the mounting groove 12, thereby affecting the performance of the lower mechanism 14 and effectively improving the performance stability of the lower mechanism 14, but also reduces the risk of localized overheating of the body 10 due to the outward transmission of high temperatures within the cooking cavity 11 and the mounting groove 12, thereby reducing the risk of burns to the user. This effectively improves the safety and performance stability of the air fryer.

[0032] In an optional embodiment, the lower base plate 13 is preferably made of a high-temperature resistant material such as PP or PPS. Using a high-temperature resistant material to make the lower base plate 13 can reduce the impact of high temperatures within the cooking cavity 11 and the mounting slot 12 on the lower base plate, effectively ensuring the performance stability of the lower base plate 13.

[0033] like Figure 1 and Figure 3As shown, in an optional embodiment, a heat dissipation duct 16 connected to the atmosphere is provided within the body 10. A heat dissipation assembly 17 for generating a cooling airflow is provided within the heat dissipation duct 16. A second heat-insulating cavity 18 is formed between the lower core 14 and the housing 10, and is connected to the heat dissipation duct 16. Providing the second heat-insulating cavity 18 between the lower core 14 and the housing 10 and connecting the second heat-insulating cavity 18 to the heat dissipation duct 16 not only reduces the risk of high temperatures within the cooking cavity 11 and the mounting slot 12 being transferred outward, causing localized overheating of the body 10 and thus scalding the user, but also allows the cooling airflow within the heat dissipation duct 16 to dissipate heat from the lower core 14, thereby ensuring the performance stability of the lower core 14 and further reducing the risk of high temperatures within the cooking cavity 11 and the mounting slot 12 being transferred outward, effectively improving the performance stability and user safety of the air fryer.

[0034] like Figure 3 As shown, in an optional embodiment, a second supporting structure 60 extending vertically is provided between the lower base plate 13 and the lower mechanism 14. The second supporting structure includes a plurality of vertically extending second supporting rods, the upper and lower portions of which are adapted to abut against the lower base plate 13 and the lower mechanism 14, respectively. Providing the second supporting structure 60 between the lower mechanism 14 and the lower base plate 13 to support the lower base plate 13 ensures the structural stability of the lower base plate 13, effectively improving the performance stability of the air fryer.

[0035] like Figure 3 As shown, in an optional embodiment, the top of the upper cover 222 is adapted to be flush with the plane of the top opening of the mounting slot 12. By arranging the top of the upper cover 22 to be flush with the plane of the top opening of the mounting slot 12, not only is it easier to remove and install the frying basket 30, but it also allows the second heating assembly 22 to be hidden, thereby improving the overall aesthetics of the machine body 10.

[0036] like Figures 1 to 3 As shown, in an optional embodiment, a plurality of upwardly extending protrusions 19 are provided at the bottom of the cooking cavity 11, surrounding the open top of the mounting slot 12. The frying basket 30 is adapted to be suspended within the cooking cavity 11 via the protrusions 19. By suspending the frying basket 30 within the cooking cavity 11 via the protrusions 19, a hot air gap is formed between the bottom of the frying basket 30 and the bottom wall of the cooking cavity 11, through which heat flow can pass. When the circulating heat flow generated by the first heating assembly 21 passes through the hot air gap, it is reheated by the second heating assembly 22, thereby compensating for heat loss caused by the circulating heat flow during the cooking process, effectively improving cooking efficiency.

[0037] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the purpose of the present invention has been fully and effectively achieved. Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. For those skilled in the art of the present invention, without departing from the present invention, several simple deductions or substitutions can be made, which should be deemed to fall within the scope of patent protection determined by the claims submitted for the present invention.
