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 a top-bottom dual-core air fryer, comprising a body, wherein a first inner cavity and a second inner cavity are provided within the body, the first inner cavity and the second inner cavity being adapted to be spaced apart from each other in an upper and lower direction, a first fan and a second fan for generating a circulating airflow being provided in the first inner cavity and the second inner cavity, respectively, and a second heating component being provided on the airflow circulation path of the second fan; a first concave cavity is provided at the bottom of the first inner cavity, the first fan being provided in the first concave cavity, a return air port corresponding to the first fan and communicating with the first concave cavity being provided on the bottom wall of the first inner cavity, and an air outlet being provided outside the return air port; a first frying basket with an open top is provided within the first inner cavity, a hot air gap being adapted to be formed between the first frying basket and the inner wall of the first inner cavity, a hot air outlet being provided at the bottom of the first frying basket corresponding to at least part of the return air port, the circulating airflow generated by the first fan being adapted to enter the hot air gap through the air outlet and then flow toward the top opening of the first frying basket, enter the first frying basket from the top opening, and flow back to the first concave cavity through the hot air outlet and the return air port; a first heating component is provided on the airflow circulation path of the first fan. By arranging the first inner cavity and the second inner cavity in the body and arranging the first inner cavity and the second inner cavity with an interval between them, not only can two foods be cooked at the same time to improve the food cooking efficiency, but also the lateral volume of the air fryer can be reduced, the space occupied by the air fryer can be reduced, and the space utilization rate can be improved; at the same time, by arranging the first fan, the first heating component and the second fan, the second heating component in the first inner cavity and the second inner cavity respectively, the food in the first inner cavity and the second cavity can be heated respectively, effectively improving the cooking efficiency and improving the user experience; in addition, by arranging the first fan at the bottom of the first inner cavity and the circulating airflow generated by the first fan is heated by the first heating component and then directed to the top of the first inner cavity, and enters the first frying basket from the top opening of the first frying basket, it can be achieved to reduce the problem of the circulating heat flow directly blowing into the first frying basket causing the food to burn, thereby 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 flange facing the top opening of the first frying basket, with the flange and the inner wall of the first frying basket defining an oil receiving chamber with an open top. By providing the upwardly folded flange around the periphery of the hot air outlet to form the oil receiving chamber with the inner wall of the first frying basket, oil and / or water generated by cooking food in the first frying basket 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, thereby effectively improving the user experience.

[0006] In an optional embodiment, a first frying plate with a through hole is suspended within the first frying basket. A sealed shielding portion is provided in the middle of the first frying plate, corresponding to the hot air outlet, and is adapted to cover the hot air outlet. Suspending the first frying plate with a through hole within the first frying basket not only supports the food, allowing the circulating heat generated by the first fan and heated by the first heating assembly to better heat the upper and lower surfaces of the food, effectively improving cooking efficiency and quality, but also provides sufficient space below the first frying plate for the circulating heat to pass through and out of the hot air outlet, effectively improving heat circulation efficiency within the first inner cavity and, thereby, improving cooking efficiency. Furthermore, providing the shielding portion on the first frying plate to cover the hot air outlet also blocks and / or diverts oil and / or water generated during cooking on the first frying plate, preventing the oil and / or water from flowing directly out of the first frying basket through the hot air outlet, thereby contaminating the external environment and / or flowing into the first concave cavity, making cleaning difficult, thereby effectively improving the user experience.

[0007] In an optional embodiment, the bottom of the first frying basket sidewall is adapted to be recessed inwardly to form an annular flange, and the first frying plate is removably secured to the annular flange. By recessing the bottom of the first frying basket sidewall inwardly to form the annular flange and removably securing the first frying plate to the annular flange, not only can the structures of the first frying basket and the first frying plate be simplified, reducing production and user costs, but also the difficulty of removing and installing the first frying plate is effectively reduced, thereby improving user convenience and user experience.

[0008] In an optional embodiment, the annular flange is provided with a plurality of hot air inlets, which are opposite to the first frying plate and communicate with the hot air gap. The first frying plate is provided with a plurality of ventilation holes around its periphery, with the ventilation holes at least partially corresponding to the hot air inlets. When the air fryer is cooking food, the outer edge of the first frying plate is blocked by the annular flange, preventing the circulating heat from heating the bottom of the food on the outer edge of the first frying plate. Therefore, by providing the hot air inlets on the annular flange, which communicate with the hot air gap, and providing the ventilation holes on the first frying plate corresponding to the hot air inlets, the circulating heat within the hot air gap can be used to heat the bottom of the food on the outer edge of the first frying plate, thereby avoiding the occurrence of differentiated cooking areas and effectively improving the cooking quality and user experience of the air fryer.

[0009] In an optional embodiment, the first frying basket sidewall is provided with a plurality of air inlet holes connecting the hot air gap and the first frying basket inner cavity. The air inlet holes are vertically extending strip-shaped holes. After the circulating airflow generated by the first fan enters the hot air gap, at least a portion thereof enters the first frying basket through the air inlet holes. Providing the air inlet holes on the first frying basket sidewall allows the circulating heat flow within the hot air gap to be directed into the first frying basket from multiple directions, thereby heating the food in the first frying basket. This not only effectively improves the cooking effect, but also effectively increases the heat flow circulation efficiency within the first inner cavity, thereby improving cooking efficiency.

[0010] In an optional embodiment, the first heating assembly includes a first heating tube, which is 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 returning to the first cavity can also be reheated to compensate for heat loss during cooking, effectively improving cooking efficiency.

[0011] In an optional embodiment, an air deflector is provided at the top of the first inner cavity, forming at least a portion of the first inner cavity. The middle portion of the air deflector is recessed downward to form a boss-shaped air guide portion facing the middle of the first inner cavity, and the air guide portion corresponds to at least a portion of the top opening of the first fryer basket. Providing the air deflector portion at the top of the first inner cavity, facing the middle of the first inner cavity and corresponding to the top opening of the first fryer basket, not only improves the flow of circulating heat within the hot air gap into the first fryer basket to heat the food in the first fryer basket, effectively improving heat circulation efficiency and cooking efficiency, but also disperses the flow of circulating heat into the first fryer basket, reducing the problem of regionalized cooking zone differentiation caused by regional concentration of circulating heat, and effectively improving cooking results.

[0012] In an optional embodiment, the first heating assembly includes a first heating tube, which is adapted to be disposed around the periphery of the air guide portion and corresponding to at least a portion of the top opening of the first frying basket. By surrounding the first heating tube outside the air guide portion, not only can the circulating airflow entering the first frying basket be heated more evenly, effectively improving heating efficiency and heating effects, but it can also reduce heat loss of the circulating heat flow upon entering the first frying basket, effectively improving cooking efficiency and cooking effects. Furthermore, by disposing the first heating tube at the top of the first inner cavity, the first heating tube can also be used to heat the top of the food in the first frying basket, effectively improving cooking efficiency and user experience.

[0013] In an optional embodiment, a mounting cavity is provided between the first and second inner cavities, and a drive motor is disposed within the mounting cavity. The drive motor's rotating shaft is adapted to extend into the first and second inner cavities, respectively, and to be drivingly connected to the first and second fans. By using the same drive motor to drive both the first and second fans, the air fryer's structure can be simplified, reducing production and operating costs. Furthermore, the air fryer's overall size can be reduced, reducing its space footprint and improving space utilization.

[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 in the body, and arranges the first inner cavity and the second inner cavity with an interval up and down, which not only can realize cooking two kinds of food at the same time to improve food cooking efficiency, but also can reduce the lateral volume of the air fryer, reduce the space occupied by the air fryer, and improve space utilization; at the same time, by respectively providing the first fan, the first heating component and the second fan, the second heating component in the first inner cavity and the second inner cavity, it is possible to heat the food in the first inner cavity and the second cavity respectively, effectively improve cooking efficiency and improve user experience; in addition, by providing the first fan at the bottom of the first inner cavity, and the circulating airflow generated by the first fan is heated by the first heating component and then directed to the top of the first inner cavity, and enters the first frying basket from the top opening of the first frying basket, it is possible to reduce the problem of the circulating heat flow directly blowing into the first frying basket causing the food to burn, and effectively improve the cooking effect.

The air fryer includes a body 10, a cooking cavity 11 with an open front side provided in the body 10, and a hot air circulation system 20 connected to the cooking cavity 11. The hot air circulation system 20 is suitable for generating a circulating heat flow and passing it into the cooking cavity 11 to cook the food in the cooking cavity 11.

[0032] like Figure 2As shown, the cooking cavity 11 includes a first inner cavity 111 and a second inner cavity 112, and the first inner cavity 111 and the second inner cavity 112 are suitable for being arranged in an upper and lower interval; the hot air circulation system 20 includes a first hot air circulation system 21 and a second hot air circulation system 22, and the first hot air circulation system 21 and the second hot air circulation system 22 are suitable for connecting the first inner cavity 111 and the second inner cavity 112 respectively to transport circulating heat flow into the first inner cavity 111 and the second inner cavity 112, thereby cooking the food in the first inner cavity 111 and the second inner cavity 112.

[0033] like Figure 2 As shown, the first hot air circulation system 21 includes a first fan 211 and a first heating component 212. A first concave cavity 1111 is provided at the bottom of the first inner cavity 111, and the first fan 211 is arranged in the first concave cavity 1111; a return air port 113 corresponding to the first fan 211 and connected to the first concave cavity 1111 is provided on the bottom wall of the first inner cavity 111, and an air outlet 114 is provided on the outer side of the return air port 113; a first frying basket 30 with an open top is provided in the first inner cavity 111, and a hot air gap 115 is formed between the first frying basket 30 and the inner wall of the first inner cavity 111. The bottom of the first frying basket 30 A hot air outlet 31 is provided corresponding to at least a portion of the return air outlet 113. The circulating airflow generated by the first fan 211 is adapted to enter the hot air gap 115 through the air outlet 114 and then flow toward the top opening of the first frying basket 30. The circulating airflow enters the first frying basket 30 from the top opening and flows back into the first concave cavity 1111 through the hot air outlet 31 and the return air outlet 113. The first heating component 212 is adapted to be arranged on the airflow circulation path of the first fan 211 to heat the circulating airflow generated by the first fan 211 to form a circulating heat flow, thereby heating the food in the first frying basket 30.

[0034] like Figure 2 As shown, the second hot air circulation system 22 includes a second fan 221 and a second heating assembly 222. A second recessed cavity 1121 is provided at the top of the second inner chamber 112. The second fan 221 and the second heating assembly 222 are adapted to be disposed within the second recessed cavity 1121, with the second heating assembly 222 positioned below the second fan. A second frying basket 40 with an open top is disposed within the second inner chamber 112, with the top opening of the second frying basket 40 at least partially corresponding to the second hot air circulation system 22. This arrangement allows the circulating heat generated by the second hot air circulation system 22 to enter the second frying basket 40 more effectively and quickly, heating the food therein and effectively improving cooking efficiency.

[0035] The air fryer is provided with the first inner cavity 111 and the second inner cavity 112 in the body 10, and the first inner cavity 111 and the second inner cavity 112 are arranged in an upper and lower interval, so that two kinds of food can be cooked at the same time to improve the cooking efficiency of food, and the lateral volume of the air fryer can be reduced to reduce the space occupied by the air fryer and improve the space utilization rate; at the same time, the first fan 211, the first heating component 212 and the second fan 221, the second heating component 222 are respectively provided in the first inner cavity 111 and the second inner cavity 112. The component 222 can heat the food in the first inner cavity 111 and the second inner cavity 112 respectively, effectively improving the cooking efficiency and improving the user experience. In addition, by arranging the first fan 211 at the bottom of the first inner cavity 111, and heating the circulating airflow generated by the first fan 211 through the first heating component 212 and then directing it to the top of the first inner cavity 111, and entering the first frying basket 30 from the top opening of the first frying basket 30, it is possible to reduce the problem of the circulating heat flow directly blowing into the first frying basket 30 and causing the food to burn, thereby effectively improving the cooking effect.

[0036] like Figure 2 As shown, the top of the first inner cavity 111 is provided with an air deflector 12 that forms at least a portion of the first inner cavity 111. The middle portion of the air deflector 12 is recessed downward to form a boss-like air guide portion 121 facing the middle of the first inner cavity 111. The air deflector portion 121 is adapted to correspond to at least a portion of the top opening of the first frying basket 30. By providing the air deflector 121 at the top of the first inner cavity 111, facing the middle of the first inner cavity 111 and corresponding to the top opening of the first frying basket 30, the circulating heat flow within the hot air gap 115 is not only better directed into the first frying basket 30 to heat the food in the first frying basket 30, effectively improving heat flow circulation and cooking efficiency, but also disperses the circulating heat flow into the first frying basket 30, reducing the problem of regionalized cooking zone differentiation caused by the regional concentration of circulating heat flow, and effectively improving cooking results.

[0037] like Figure 2As shown, the first heating assembly 212 includes a first heating tube 2121 and a fixing member for fixing the first heating tube. The first heating tube 2121 is adapted to be arranged around the periphery of the air guide portion 121 and corresponds to at least a portion of the top opening of the first frying basket 30. By surrounding the outside of the air guide portion 121, the first heating tube 2121 can not only better and more evenly heat the circulating airflow entering the first frying basket 30, effectively improving heating efficiency and heating effect, but also reduce heat loss of the circulating heat flow upon entering the first frying basket 30, effectively improving cooking efficiency and cooking effect. At the same time, by arranging the first heating tube 2121 at the top of the first inner cavity 111, the first heating tube 2121 can also be used to heat the top of the food in the first frying basket 30, effectively improving cooking efficiency and user experience.

[0038] like Figure 3 and Figure 4 As shown, the periphery of the hot air outlet 31 is adapted to fold upward to form a flange 32 that faces the top opening of the first frying basket 30. The flange 32 and the inner wall of the first frying basket 30 define an open-top oil receiving chamber 33. The oil receiving chamber 33 is adapted to collect and store oil and / or water generated during cooking of food within the first frying basket 30. By providing the upwardly folded flange 32 around the periphery of the hot air outlet 31 to form the oil receiving chamber 33 with the inner wall of the first frying basket 30, the oil and / or water generated during cooking within the first frying basket 30 can be collected and blocked, thereby preventing the oil and / or water from flowing out of the hot air outlet 31 and contaminating the external environment. Furthermore, the oil and / or water within the first frying basket 30 from flowing out of the hot air outlet 31 and entering the first concave cavity 1111, thereby making cleaning difficult, effectively improving the user experience.

[0039] like Figure 3 and Figure 4As shown, a first frying plate 50 with through holes is suspended in the first frying basket 30. A shielding portion 51 having a sealed structure corresponding to the hot air outlet 31 is provided in the middle of the first frying plate 50. The shielding portion 51 is suitable for covering the hot air outlet 31. By suspending the first frying plate 50 with through holes in the first frying basket 30, not only can the food be supported so that the circulating heat flow generated by the first fan 211 and heated by the first heating component 212 can better heat the upper and lower surfaces of the food, effectively improving the cooking efficiency and cooking effect of the food, but also sufficient space can be reserved under the first frying plate 50 for the circulating heat flow to pass through and flow out of the hot air outlet 31, effectively improving the heat flow circulation efficiency in the first inner cavity 111, thereby improving the cooking efficiency. At the same time, by providing the shielding portion on the first frying plate 50, The hot air outlet 31 is covered by the cover 51, which not only blocks the oil and / or water generated when cooking food on the first frying plate 50, thereby preventing the oil and / or water from directly flowing out of the first frying basket 30 through the hot air outlet 31, thereby polluting the external environment and flowing into the first concave cavity 1111, thereby making cleaning difficult, but also guides the oil and / or water generated when cooking food on the first frying plate 50, so that the oil and / or water on the first frying plate 50 can flow into the oil receiving cavity 33 better and be collected by the oil receiving cavity 33, thereby effectively improving the user experience.

[0040] like Figure 4 As shown, the bottom of the sidewall of the first frying basket 30 is adapted to be recessed inward to form an annular flange 34, and the first frying plate 50 is adapted to be removably secured to the annular flange 34. By recessing the bottom of the sidewall of the first frying basket 30 inward to form the annular flange 34 and removably securing the first frying plate 50 to the annular flange 34, not only can the structures of the first frying basket 30 and the first frying plate 50 be simplified, reducing production costs and user costs, but also effectively reducing the difficulty of removing and installing the first frying plate 50, thereby improving user convenience and user experience.

[0041] like Figure 4 and Figure 5As shown, the annular flange 34 is provided with a plurality of hot air inlets 35, which are opposite to the first frying plate 50 and communicate with the hot air gap 115. A plurality of ventilation holes 52 are provided around the periphery of the first frying plate 50, with the ventilation holes 52 at least partially corresponding to the hot air inlets 35. When cooking food in the air fryer, the outer edge of the first frying plate 50 is blocked by the annular flange 34, preventing the circulating heat from heating the bottom of the food on the outer edge of the first frying plate 50. Therefore, by providing the hot air inlets 35 on the annular flange 34, which communicate with the hot air gap 115, and by providing the ventilation holes 52 on the first frying plate 50 corresponding to the hot air inlets 35, the circulating heat within the hot air gap 115 can be used to heat the bottom of the food on the outer edge of the first frying plate 50, thereby avoiding the occurrence of different cooking areas and effectively improving the cooking quality and user experience of the air fryer.

[0042] like Figure 2 As shown, a mounting cavity 13 is provided between the first inner cavity 111 and the second inner cavity 112. A drive motor 60 is disposed within the mounting cavity 13. The drive motor 60 is preferably a dual-shaft motor, with the rotating shafts at both ends of the drive motor 60 extending into the first inner cavity 111 and the second inner cavity 112, respectively, to drive and connect with the first fan 211 and the second fan 221. By using the same drive motor 60 to drive the first fan 211 and the second fan 221, the structure of the air fryer can be simplified, reducing production and operating costs. The overall volume of the air fryer can also be reduced, reducing the space occupied by the air fryer and improving space utilization.

[0043] Example 2:

[0044] like Figures 6 to 8 2 is a schematic diagram of a first 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 lies in the different structures of the first hot air circulation system 21 and the first frying basket 30.

[0045] like Figures 6 to 8 As shown, the air fryer includes a body 10A, a cooking cavity 11A with an open front side arranged in the body 10A, and a hot air circulation system 20A connected to the cooking cavity 11A. The hot air circulation system 20A is suitable for generating a circulating heat flow and passing it into the cooking cavity 11A to cook the food in the cooking cavity 11A.

[0046] like Figure 2As shown, the cooking cavity 11A includes a first inner cavity 111A and a second inner cavity 112A, and the first inner cavity 111A and the second inner cavity 112A are suitable for being arranged in an upper and lower interval; the hot air circulation system 20A includes a first hot air circulation system 21A and a second hot air circulation system 22A, and the first hot air circulation system 21A and the second hot air circulation system 22A are suitable for respectively connecting the first inner cavity 111A and the second inner cavity 112A to transport circulating heat flow into the first inner cavity 111A and the second inner cavity 112A, thereby cooking the food in the first inner cavity 111A and the second inner cavity 112A.

[0047] like Figure 6 As shown, the first hot air circulation system 21A includes a first fan 211A and a first heating assembly 212A. The first heating assembly 212A includes a first heating pipe 2121A and a fixing member for fixing the first heating pipe 2121A. A first concave cavity 1111A is provided at the bottom of the first inner cavity 111A. The first fan 211A and the first heating pipe 2121A are disposed within the first concave cavity 1111A, with the first heating pipe 2121A located above the first fan 211A. By disposing the first heating pipe 2121A within the first concave cavity 1111A and above the first fan 211A, not only can the first heating pipe 2121A be hidden, thereby improving the overall aesthetics of the air fryer, but the circulating heat flow returning to the first concave cavity 1111A can also be reheated to compensate for heat loss caused by the circulating heat flow during cooking, effectively improving cooking efficiency.

The hot air generated by the first fan 211A The circulating airflow is adapted to enter the hot air gap 115A through the air outlet 114A and then flow toward the top opening of the first frying basket 30A, enter the first frying basket 30A through the top opening, and flow back into the first concave cavity 1111A through the hot air outlet 31A and the return air port 113A; the first heating component 212A is adapted to be arranged on the airflow circulation path of the first fan 211A to heat the circulating airflow generated by the first fan 211A to form a circulating heat flow, thereby heating the food in the first frying basket 30A.

[0049] In addition, if Figures 6 to 8 As shown, the sidewall of the first frying basket 30A is further provided with a plurality of air inlet holes 36A that connect the hot air gap 115A and the interior cavity of the first frying basket 30A. The air inlet holes 36A are preferably vertically extending strip-shaped holes. After the circulating airflow generated by the first fan 211A enters the hot air gap 115A, at least a portion thereof passes through the air inlet holes 36A and enters the first frying basket 30A. By providing the air inlet holes 36A on the sidewall of the first frying basket 30A, the circulating heat flow within the hot air gap 115A can be directed into the first frying basket 30A from multiple directions, thereby heating the food in the first frying basket 30A. This not only effectively improves the cooking effect, but also effectively increases the heat flow circulation efficiency within the first interior cavity 111A, thereby improving cooking efficiency and effectively enhancing the user experience.
