Description

Technical Field

[0001] The utility model relates to the field of air fryers, in particular to an upper and lower dual-core air fryer. Background Art

[0002] With the improvement of people's living standards, the oil-free cooking method of air fryers is becoming more and more popular. However, most of the existing air fryers are single-pot air fryers, that is, they only have one cooking chamber and one frying basket. This type of air fryer can only cook one type of food at a time, with slow cooking speed, low cooking efficiency, and poor user experience. In order to meet user needs, a type of double-pot air fryer has appeared on the market. Most of these air fryers have one cooking chamber and two frying baskets arranged in parallel in the cooking chamber, which can cook two types of food at the same time. However, since there is only one frying and baking component in the cooking chamber, the cooking speed is slow and the cooking efficiency is low. Moreover, the parallel arrangement of the two frying baskets will increase the size of the air fryer, occupy a larger desktop area, have a high space occupancy rate, and have a poor user experience. Utility Model Content

[0003] The present application provides an upper and lower dual-core air fryer to solve the technical problems of low cooking efficiency, high space occupancy and poor user experience of existing air fryers.

[0004] In order to solve the above technical problems, the utility model provides an upper and lower dual-core air fryer, including a body, a first inner cavity and a second inner cavity are provided in the body, the first inner cavity and the second inner cavity are suitable for being spaced apart in an upper and lower manner, a first fan and a second fan for generating a circulating airflow are respectively provided in the first inner cavity and the second inner cavity, and a second heating component is provided on the airflow circulation path of the second fan; a first concave cavity which is concave downwards is provided at the bottom of the first inner cavity, the first fan is provided in the first concave cavity, a return air port corresponding to the first fan and connected to the first concave cavity is provided on the bottom wall of the first inner cavity, and an air outlet is provided on the outside of the return air port; a first frying basket with an open top is provided in the first inner cavity, the first frying basket includes an outer pot and an inner pot suspended in the outer pot, the side wall of the inner pot is connected to the A first hot air gap connected to the inner cavity of the inner pot is formed between the side walls of the outer pot, a second hot air gap is formed between the bottom wall of the inner pot and the bottom wall of the outer pot, the bottom of the outer pot is provided with a hot air outlet connected to the second hot air gap and corresponding to at least part of the return air port, a hot air inlet connected to the first hot air gap and at least partly corresponding to the air outlet is provided on the outside of the hot air outlet, the bottom of the inner pot is provided with ventilation holes, the circulating air flow generated by the first fan is suitable for entering the first hot air gap through the air outlet and the hot air inlet and flowing toward the top opening of the inner pot, entering the inner pot from the top opening of the inner pot and flowing back to the first concave cavity through the ventilation holes, the second hot air gap, the hot air outlet and the return air port, and a first heating component is provided on the air flow circulation path of the first fan.By arranging the first inner cavity and the second inner cavity spaced apart in an upper and lower manner in the machine body, and arranging the first fan, the first heating component, the second fan, and the second heating component in the first inner cavity and the second inner cavity respectively, not only can the lateral volume of the air fryer be reduced, the space occupied by the air fryer be reduced, and the space utilization rate be improved, but also the first fan, the first heating component, the second fan, and the second heating component can be used to heat the food in the first inner cavity and the second inner cavity respectively at the same time, thereby effectively improving the cooking efficiency; at the same time, by arranging the first fan at the bottom of the first inner cavity and transmitting the circulating heat flow generated by the first fan and the first heating component through the The hot air is directed through the first hot air gap to the top of the inner pot, enters the inner pot from the top opening of the inner pot, and flows back to the first concave cavity from the ventilation holes and the second hot air gap at the bottom of the inner pot via the hot air outlet and the return air port. This not only reduces the problem of the circulating heat flow directly blowing into the inner pot and causing the food to burn, but also heats the upper and lower surfaces of the food in the inner pot, effectively improving the cooking efficiency and cooking effect. In addition, by configuring the first frying basket into an inner and outer double-layer structure and providing the first hot air gap connected to the first concave cavity between the inner pot and the outer pot, the circulating heat flow can be introduced into the inner pot from the top peripheral side of the inner pot, thereby heating the food in the inner pot and effectively improving the cooking effect.

[0005] In an optional embodiment, the periphery of the hot air outlet is adapted to fold upward to form a folded portion facing the top opening of the outer pot, and the folded portion and the inner wall of the outer pot are adapted to enclose an open-top oil receiving chamber. By providing the upwardly folded portion around the periphery of the hot air outlet to form the oil receiving chamber with the inner wall of the outer pot, oil and / or water flowing out of the inner pot through the ventilation holes can be collected and blocked, thereby preventing the oil and / or water from flowing out of the hot air outlet and contaminating the external environment and / or flowing into the first concave cavity, thereby making cleaning difficult, and effectively improving the user experience.

[0006] In an optional embodiment, a shielding portion having a sealed structure is provided on the bottom wall of the inner pot, corresponding to the hot air outlet, and is adapted to cover the hot air outlet. By providing the shielding portion on the bottom wall of the inner pot, which covers the hot air outlet and has a sealed structure, oil and / or water generated during cooking in the inner pot can be blocked and / or diverted, thereby preventing the oil and / or water from flowing directly out of the outer pot through the hot air outlet, thereby contaminating the external environment and / or flowing into the first concave cavity, making cleaning difficult. This effectively improves the user experience.

[0007] In an optional embodiment, the shielding portion is formed by an upward depression of the inner pot bottom wall. By forming the shielding portion by an upward depression of the inner pot bottom wall, the structure of the inner pot can be simplified, reducing production and operating costs. Furthermore, sufficient space between the shielding portion and the folded portion can be ensured for circulating heat flow, thereby improving heat flow circulation efficiency and cooking efficiency within the first frying basket.

[0008] In an optional embodiment, the bottom of the inner sidewall of the outer pot is adapted to be recessed inwardly to form an annular flange, and the bottom of the outer sidewall of the inner pot is adapted to be recessed inwardly to form a recessed portion that matches the flange, and the inner pot is adapted to be removably retained on the flange by the recessed portion. By recessing the bottom of the inner sidewall of the outer pot inwardly to form the annular flange and removably retaining the inner pot on the flange by the recessed portion, the structure of the first frying basket can be simplified while ensuring the supporting strength of the flange, thereby reducing production costs and user costs. Furthermore, the recessed portion is adapted to position and / or retain the inner pot. Positioning and / or retaining the inner pot by the recessed portion not only effectively reduces the difficulty of installing the inner pot and improves user convenience, but also prevents the inner pot from sliding and blocking a portion of the hot air inlet, thereby preventing some circulating heat from properly entering the first frying basket and causing different cooking areas, thereby effectively improving the user experience.

[0009] In an optional embodiment, the flange on the outer side of the inner pot is provided with a plurality of hot air inlets, which are adapted to be arranged around the outer periphery of the inner pot. By providing a plurality of hot air inlets around the outer periphery of the inner pot, not only can the circulating heat flow enter the first hot air gap more quickly and effectively, thereby effectively improving the heat flow circulation efficiency within the first frying basket and thus improving cooking efficiency, but the circulating heat flow can also be directed from the inner pot's top periphery into the inner pot, thereby heating the food within the inner pot, reducing the problem of uneven distribution of the circulating heat flow within the inner pot, which can lead to different cooking areas, and effectively improving the cooking effect.

[0010] In an optional embodiment, the inner pot sidewall is provided with a plurality of air inlet holes connecting the first hot air gap and the inner pot cavity. The air inlet holes are vertically extending strip-shaped holes. After the circulating airflow generated by the first fan enters the first hot air gap, at least a portion thereof passes through the air inlet holes and enters the inner pot. Providing these air inlet holes on the inner pot sidewall allows the circulating heat flow within the first hot air gap to be directed into the inner pot from multiple directions, thereby heating the food within the inner pot. This not only effectively improves the cooking effect, but also effectively increases the heat flow circulation efficiency within the first frying basket, thereby improving cooking efficiency.

[0011] In an optional embodiment, the first heating assembly includes a first heating tube, which is adapted to be disposed within the first cavity and above the first fan. By disposing the first heating tube within the first cavity and above the first fan, not only can the first heating tube be concealed, thereby improving the overall aesthetics of the air fryer, but the circulating heat flow re-entering the first cavity can also be reheated to compensate for heat loss during cooking, effectively improving cooking efficiency.

[0012] In an optional embodiment, the top of the first inner cavity is provided with an air guide plate that defines at least a portion of the first inner cavity. The middle portion of the air guide plate is adapted to be recessed upward to form an air guide cavity with a downward opening, the opening of which corresponds to the top opening of the outer pot. The middle portion of the air guide cavity is provided with a flow guide portion that is recessed downward and faces the middle portion of the outer pot bottom wall, the flow guide portion corresponding to at least a portion of the top opening of the inner pot. By providing the air guide cavity at the top of the first inner cavity corresponding to the top opening of the outer pot, and providing the flow guide portion in the middle portion of the air guide cavity corresponding to at least a portion of the top opening of the inner pot, not only can the circulating heat flow within the first hot air gap be better directed into the inner pot to heat the food in the inner pot, effectively improving heat flow circulation efficiency and cooking efficiency, but the circulating heat flow can also be dispersed into the inner pot, reducing the problem of regional differentiation in cooking areas caused by regional concentration of circulating heat flow, effectively improving cooking results.

[0013] In an optional embodiment, the first heating component includes a first heating tube, which is suitable for being arranged in the air guide cavity and surrounding the outside of the air guide portion. By surrounding the first heating tube on the outside of the air guide portion in the air guide cavity, not only can the circulating airflow entering the first frying basket be heated better and more evenly, effectively improving heating efficiency and heating effect, but it can also reduce heat loss of the circulating heat flow when entering the inner pot, effectively improving cooking efficiency and cooking effect. At the same time, by arranging the first heating tube in the air guide cavity at the top of the first inner cavity, it can also be achieved that the first heating tube is used to heat the top of the food in the inner pot, effectively improving cooking efficiency and user experience.

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

[0015] The present application provides the first inner cavity and the second inner cavity with an interval between them in the upper and lower parts of the body, and respectively provides the first fan, the first heating assembly, the second fan, and the second heating assembly in the first inner cavity and the second inner cavity, thereby not only reducing the volume of the air fryer and reducing space occupation, but also achieving simultaneous heating of the food in the first inner cavity and the second inner cavity, effectively improving cooking efficiency. At the same time, by guiding the circulating heat flow through the first hot air gap to the top of the inner pot, entering the inner pot from the top opening of the inner pot, and returning to the first concave cavity from the ventilation holes and the second hot air gap at the bottom of the inner pot through the hot air outlet and the return air outlet, not only can the circulating heat flow be directly blown into the inner pot, causing problems such as burning of food, but also can heat the upper and lower surfaces of the food in the inner pot, effectively improving cooking efficiency and cooking effect. In addition, by providing the first hot air gap between the inner pot and the outer pot, which is connected to the first concave cavity, the circulating heat flow can be introduced into the inner pot from the circumference of the top of the inner pot, thereby heating the food in the inner pot, effectively improving the cooking effect.

[0025] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. 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.

[0026] 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.

[0027] 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.

[0028] 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. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0029] And for ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0030] Furthermore, it should be noted that the term "a" should be understood as "at least one" or "one or more." That is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be one or more. The term "a" should not be construed as limiting the quantity. The use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. 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.

[0031] Example 1:

[0032] Attachment Figure 1 To the attached Figure 5As shown, it is a schematic diagram of a first embodiment of a top and bottom dual-core air fryer provided by the utility model, the air fryer includes a body 10, a first inner cavity 11 and a second inner cavity 12 provided in the body 10, the first inner cavity 11 and the second inner cavity 12 are suitable for being spaced apart in an upper and lower manner, the first inner cavity 11 and the second inner cavity 12 are respectively provided with a first fan 13 and a second fan 14 for generating a circulating airflow, the first fan 13 and the second fan 14 are respectively provided with a first heating component 15 and a second heating component 16 on the airflow circulation path, the first heating component 15 and the second heating component 16 are respectively adapted to heat the circulating airflow generated by the first fan 13 and the second fan 14, thereby forming a circulating heat flow, so as to heat the food in the first inner cavity 11 and the second inner cavity 12. By providing the first inner cavity 11 and the second inner cavity 12 spaced apart in an upper and lower manner in the body 10, and respectively providing the first fan 13, the first heating component 15, the second fan 14, and the second heating component 16 in the first inner cavity 11 and the second inner cavity 12, not only can the lateral volume of the air fryer be reduced, the space occupied by the air fryer be reduced, and the space utilization rate be improved, but the first fan 13, the first heating component 15, the second fan 14, and the second heating component 16 can also be used to heat the food in the first inner cavity 11 and the second inner cavity 12 simultaneously, thereby effectively improving the cooking efficiency.

[0033] like Figure 2As shown, the bottom of the first inner cavity 11 is provided with a first concave cavity 17 which is concave downwards, the first fan 13 is provided in the first concave cavity 17, the bottom wall of the first inner cavity 11 is provided with a return air port 111 corresponding to the first fan 13 and connected to the first concave cavity 17, and an air outlet 112 is provided on the outside of the return air port 111; a first frying basket 20 with an open top is provided in the first inner cavity 11, the first frying basket 20 includes an outer pot 21 and an inner pot 22 suspended in the outer pot 21, a first hot air gap 23 connected to the inner cavity of the inner pot 22 is formed between the side wall of the inner pot 22 and the side wall of the outer pot 21, a second hot air gap 24 is formed between the bottom wall of the inner pot 22 and the bottom wall of the outer pot 21, and the bottom of the outer pot 21 is provided with a first hot air gap 25 connected to the inner cavity of the inner pot 22. A second hot air gap 24 is provided and a hot air outlet 211 corresponds to at least part of the return air port 111. A hot air inlet 212 is provided on the outside of the hot air outlet 211, which is connected to the first hot air gap 23 and at least partly corresponds to the air outlet 112. A ventilation hole 221 is provided at the bottom of the inner pot 22. The circulating airflow generated by the first fan 13 is suitable for entering the first inner cavity 11 through the air outlet 112, entering the first hot air gap 23 from the hot air inlet 212 and flowing toward the top opening of the inner pot 22. It enters the inner pot 22 from the top opening of the inner pot 22 and flows back to the first concave cavity 17 through the ventilation hole 221, the second hot air gap 24, the hot air outlet 211 and the return air port 111. By arranging the first fan 13 at the bottom of the first inner cavity 11, and guiding the circulating heat flow generated by the first fan 13 and the first heating component 15 to the top of the inner pot 22 through the first hot air gap 23, entering the inner pot 22 from the top opening of the inner pot 22, and returning to the first concave cavity 17 from the ventilation holes 221 and the second hot air gap 24 at the bottom of the inner pot 22 through the hot air outlet 211 and the return air port 111, it is possible to reduce the problem of food burning caused by the circulating heat flow directly blowing into the inner pot 22. It is also possible to heat the upper and lower surfaces of the food in the inner pot 22, thereby effectively improving the cooking efficiency and cooking effect. At the same time, by setting the first frying basket 20 as an inner and outer double-layer structure, and setting the first hot air gap 23 connected to the first concave cavity 17 between the inner pot 22 and the outer pot 21, it is possible to introduce the circulating heat flow from the top peripheral side of the inner pot 22 into the inner pot 22, thereby heating the food in the inner pot 22, reducing the problem of differentiated cooking areas due to uneven distribution of the circulating heat flow in the inner pot 22, and effectively improving the cooking effect.

[0034] like Figure 2 、 Figure 4 and Figure 5As shown, the hot air outlet 211 is provided with a folded portion 213 formed by folding the bottom wall of the outer pot 21 upward. The folded portion 213 is adapted to open toward the top of the outer pot, and the folded portion 213 and the inner wall of the outer pot 21 are adapted to form an open-top oil receiving chamber 214. When cooking food in the inner pot 22, oil and / or water are produced. This oil and / or water flows into the outer pot through the ventilation holes 221. Therefore, by providing the folded portion 213 around the hot air outlet 211, forming the oil receiving chamber 214 with the inner wall of the outer pot 21, the oil and / or water flowing out of the inner pot 21 through the ventilation holes 221 can be collected and blocked. This prevents the oil and / or water from flowing out of the hot air outlet 221 and contaminating the external environment, flowing into the first concave cavity 17, or dripping onto the first fan 13, which could cause cleaning difficulties. This effectively improves the user experience.

[0035] like Figures 2 to 6 As shown, a shielding portion 222 corresponding to the hot air outlet 211 and having a sealed structure is provided on the bottom wall of the inner pot 22 , and the shielding portion 222 is suitable for covering the hot air outlet 211 . By providing the shielding portion 222 with a sealed structure on the bottom wall of the inner pot 22 to cover the hot air outlet 211, the oil and / or water generated when cooking food in the inner pot 22 can be blocked, which not only prevents the oil and / or water from directly flowing out of the outer pot 21 through the hot air outlet 211, thereby polluting the external environment, but also prevents the oil and / or water from directly flowing out of the outer pot 21 through the hot air outlet 211 and then flowing into the first concave cavity, thereby causing cleaning difficulties, etc., effectively improving the user experience; at the same time, the shielding portion 222 is also suitable for guiding the oil and / or water generated when cooking food in the inner pot 22, so as to better guide the oil and / or water in the inner pot 22 into the oil receiving cavity 214, so that they are collected by the oil receiving cavity 214, which can effectively improve the collection effect of the oil receiving cavity 214.

[0036] like Figures 2 to 5 As shown, the shielding portion 222 is formed by an upward depression in the bottom wall of the inner pot 22. By forming the shielding portion 222 by an upward depression in the bottom wall of the inner pot 22, the structure of the inner pot 22 is simplified, reducing production and operating costs. Furthermore, sufficient space is ensured between the shielding portion 222 and the folded portion 213 for circulating heat flow, thereby improving heat flow circulation efficiency and cooking efficiency within the first frying basket 20.

[0037] like Figure 2 、 Figure 4 and Figure 5As shown, the bottom of the inner side wall of the outer pot 21 is adapted to be recessed inward to form an annular flange 215, and the bottom of the outer side wall of the inner pot 22 is adapted to be recessed inward to form a recessed portion 223 that matches the flange 215. The inner pot 22 is adapted to be detachably restrained on the flange 215 by the recessed portion 223. By recessing the bottom of the inner side wall of the outer pot 21 inward to form the annular flange 215 and detachably restraining the inner pot 22 on the flange 215 by the recessed portion 223, not only can the structure of the first frying basket 20 be simplified while ensuring the supporting strength of the flange 215, thereby reducing production costs and user costs, but also the difficulty of disassembling the inner pot 22 can be reduced, thereby improving user convenience. At the same time, the recessed portion 223 is adapted to play a positioning role in the installation of the inner pot 22. The inner pot 22 is positioned by the recessed portion 223, which can effectively reduce the difficulty of installing the inner pot and improve the convenience of user use. In addition, the recessed portion 223 is also suitable for limiting the inner pot 22. By limiting the inner pot 22 by the recessed portion 223, it can be avoided that the inner pot 22 blocks part of the hot air inlet 212 due to sliding, causing part of the circulating heat flow to be unable to normally enter the first frying basket 20, thereby causing the problem of differentiated cooking areas, thereby effectively improving the user experience.

[0038] like Figures 4 to 6 As shown, the flange 215 on the outside of the inner pot 22 is provided with a plurality of hot air inlets 212, which are adapted to be arranged around the outer periphery of the inner pot 22. By providing a plurality of hot air inlets 212 around the outer periphery of the inner pot 22, not only can the circulating heat flow enter the first hot air gap 23 more quickly and effectively, thereby effectively improving the heat flow circulation efficiency within the first frying basket 20 and thus improving cooking efficiency, but the circulating heat flow can also be introduced into the inner pot 22 from the top periphery of the inner pot 22, thereby heating the food in the inner pot 22, reducing the problem of uneven distribution of the circulating heat flow within the inner pot 22, which can lead to different cooking areas, and effectively improving the cooking effect.

[0039] like Figure 2As shown, the top of the first inner cavity 11 is provided with an air guide plate 18 which constitutes at least part of the first inner cavity 11, and the middle part of the air guide plate 18 is suitable for being recessed upward to form an air guide cavity 181 opening downward, and the opening of the air guide cavity 181 is suitable for corresponding to the top opening of the outer pot 21; the middle part of the air guide cavity 181 is provided with a guide portion 182 which is recessed downward and faces the middle part of the bottom wall of the outer pot 21, and the guide portion 182 is suitable for corresponding to at least part of the top opening of the inner pot 22. By setting the air guide cavity 181 corresponding to the top opening of the outer pot 21 at the top of the first inner cavity 11, and setting the guide portion 182 corresponding to at least part of the top opening of the inner pot 22 in the middle of the air guide cavity 181, not only can the circulating heat flow in the first hot air gap 23 be better introduced into the inner pot 22 to heat the food in the inner pot 22, effectively improving the heat flow circulation efficiency and cooking efficiency, but also the circulating heat flow can be dispersedly introduced into the inner pot 22 to reduce the problem of differentiation of cooking areas due to regional aggregation of circulating heat flow, thereby effectively improving the cooking effect.

[0040] like Figure 2 As shown, the first heating assembly 15 includes a first heating tube 151 and a plurality of fixing members for fixing the first heating tube 151. The first heating tube is adapted to be fixed within the air guide cavity 181 by the fixing members and is disposed around the outside of the air guide portion 182. By surrounding the first heating tube 151 around the outside of the air guide portion 182 within the air guide cavity 181 and fixing it with the fixing members, not only can the circulating airflow entering the first frying basket 20 be heated better and more evenly, effectively improving heating efficiency and heating effect, but also can reduce heat loss of the circulating heat flow when entering the inner pot 22, effectively improving cooking efficiency and cooking effect. At the same time, by arranging the first heating tube 151 within the air guide cavity 181 at the top of the first inner cavity 11, the first heating tube 151 can also be used to heat the top of the food in the inner pot, effectively improving cooking efficiency and user experience.

[0041] like Figure 2 As shown, a mounting cavity 19 is provided between the first inner cavity 11 and the second inner cavity 12. A drive motor 30 is housed within the mounting cavity 19. The drive motor 30 is preferably a dual-shaft motor, with the rotating shafts at both ends of the drive motor 30 extending into the first inner cavity 11 and the second inner cavity 12, respectively, to drive and connect with the first fan 13 and the second fan 14. By using the same drive motor 30 to drive the first fan 13 and the second fan 14, the structure of the air fryer can be simplified, reducing production and operating costs. The overall size of the air fryer can also be reduced, reducing the space occupied by the air fryer and improving space utilization.

[0042] Example 2:

[0043] Attachment Figure 7 To the attached Figure 9 As shown, it is a schematic diagram of a second embodiment of an upper and lower dual-core air fryer provided by the present invention. Compared with the air fryer in the first embodiment, the air fryer in the second embodiment has some identical structures and functions, which will not be repeated here. Compared with the air fryer in the first embodiment, the difference between the air fryer in the second embodiment and the air fryer in the first embodiment is that the setting position of the first heating component 15 and the structure of the first frying basket 20 are different.

[0044] like Figure 7 As shown, the air fryer includes a body 10A, a first inner cavity 11A and a second inner cavity 12A provided in the body 10A, the first inner cavity 11A and the second inner cavity 12A are suitable for being spaced apart in an upper and lower manner, the first inner cavity 11A and the second inner cavity 12A are respectively provided with a first fan 13A and a second fan 14A for generating a circulating airflow, the first fan 13A and the second fan 14A are respectively provided with a first heating component 15 and a second heating component 16A on the airflow circulation paths, the first heating component 15A and the second heating component 16 are respectively adapted to heat the circulating airflow generated by the first fan 13A and the second fan 14A, thereby forming a circulating heat flow, so as to heat the food in the first inner cavity 11A and the second inner cavity 12A.

[0045] like Figure 7 As shown, the bottom of the first inner cavity 11A is provided with a downwardly recessed first cavity 17A. The first heating assembly 15A includes a first heating tube 151A and multiple fixings for securing the first heating tube 151A. The first heating tube 151A and the first fan 13A are adapted to be disposed within the first cavity 17A, with the first heating tube 151A adapted to be positioned above the first fan 13A. By disposing the first heating tube 151A within the first cavity 17A and above the first fan 13A, not only is the first heating tube 151A concealed, thereby enhancing the overall aesthetics of the air fryer, but the circulating heat flow re-entering the first cavity 17A is also reheated to compensate for heat loss during cooking, effectively improving cooking efficiency.

[0046] like Figures 7 to 9As shown, a return air port 111A is provided on the bottom wall of the first inner cavity 11A, which corresponds to the first fan 13A and is connected to the first concave cavity 17A, and an air outlet 112A is provided on the outside of the return air port 111A; a first frying basket 20A with an open top is provided in the first inner cavity 11A, and the first frying basket 20A includes an outer pot 21A and an inner pot 22A suspended in the outer pot 21A, and a first hot air gap 23A is formed between the side wall of the inner pot 22A and the side wall of the outer pot 21A to connect to the inner cavity of the inner pot 22A, and a second hot air gap 24A is formed between the bottom wall of the inner pot 22A and the bottom wall of the outer pot 21A, and a hot air gap 23A is formed at the bottom of the outer pot 21A to connect to the second hot air gap 23A and correspond to at least part of the return air port 111A. Outlet 211A, a hot air inlet 212A is provided on the outside of the hot air outlet 211A, which is connected to the first hot air gap 23A and at least partially corresponds to the air outlet 112A, and a ventilation hole 221A is provided at the bottom of the inner pot 22A. The circulating heat flow generated by the first fan 13A and the first heating component 15A is suitable for entering the first inner cavity 11A through the air outlet 112A, entering the first hot air gap 23A from the hot air inlet 212A and flowing toward the top opening of the inner pot 22A, entering the inner pot 22A from the top opening of the inner pot 22A and returning to the first concave cavity 17A through the ventilation hole 221A, the second hot air gap 24A, the hot air outlet 211A and the return air port 111A.

[0047] like Figures 7 to 9 As shown, the sidewall of the inner pot 22A is provided with a plurality of air inlet holes 224A that connect the first hot air gap 23A with the inner cavity of the inner pot 22A. The air inlet holes 224A are preferably vertically extending strip-shaped holes. The circulating heat flow generated by the first fan 13A and the first heating tube 151A enters the first hot air gap 23A and at least partially passes through the air inlet holes 224A into the inner pot 22A. By providing the air inlet holes 224A on the sidewall of the inner pot 22A, the circulating heat flow within the first hot air gap 23A can be directed into the inner pot 22A from multiple directions, thereby heating the food in the inner pot 22A. This not only effectively improves the cooking effect, but also effectively increases the heat flow circulation efficiency within the first frying basket 20A, thereby improving cooking efficiency.
