Description

Technical Field

[0001] This utility model relates to the field of kitchen appliances, and in particular to a dual-core air fryer with good heat dissipation. Background Technology

[0002] As people's living standards improve, the usage rate of air fryers is also increasing. Most existing air fryers are single-cavity air fryers, which can only cook one type of food at a time, resulting in low cooking efficiency and a poor user experience. To meet user needs, a type of dual-cavity air fryer has emerged on the market. This type of air fryer has two independent cavities, which can cook multiple foods at the same time. However, due to its larger overall size and poor heat dissipation, the user experience is also poor. Utility Model Content

[0003] This application provides a dual-core air fryer with good heat dissipation to solve the technical problems of existing air fryers having a large overall size, poor heat dissipation, and poor user experience.

[0004] To solve the above-mentioned technical problems, this utility model provides a dual-core air fryer with good heat dissipation, including a body, a cooking cavity disposed within the body, and a heat dissipation duct disposed outside the cooking cavity. The cooking cavity includes a first cooking cavity and a second cooking cavity arranged vertically at intervals. The heat dissipation duct includes a first heat dissipation duct and a second heat dissipation duct arranged vertically and interconnected. A first air guide shroud is provided above the first cooking cavity. One side of the first air guide shroud extends to the rear side of the body and communicates with a first vent on the rear side wall of the body. A first air outlet communicating with the first heat dissipation duct is provided above the first air guide shroud. A first cooling fan is provided in the first air guide shroud, and the middle air intake area of ​​the first cooling fan corresponds to the first air outlet. A second air guide shroud is provided above the second cooking cavity. One side of the second air guide shroud extends to the rear side of the body and communicates with a second vent on the rear side wall of the body. A second air outlet communicating with the second heat dissipation duct is provided above the second air guide shroud. A second cooling fan is provided in the second air guide shroud, and the middle air intake area of ​​the second cooling fan corresponds to the second air outlet. By arranging the first and second cooking chambers vertically spaced within the air fryer, the air fryer can cook multiple foods simultaneously, effectively improving cooking efficiency. This also reduces the lateral volume of the air fryer, minimizing its space requirements for easier storage and transportation. Furthermore, the interconnected first and second cooling ducts within the air fryer allow for efficient cooling of the cooking chambers, improving both cooling efficiency and effectiveness. This ensures that the air fryer can maintain overall cooling regardless of whether food is being cooked in either the first or second cooking chamber, guaranteeing performance stability and safety. Furthermore, by covering the outside of the first cooling fan and the second cooling fan with the first air guide shroud and the second air guide shroud respectively, and setting the first air outlet and the second air outlet to correspond to the middle air intake area of ​​the first cooling fan and the second cooling fan respectively, not only can the first air guide shroud and the second air guide shroud block, collect and guide the cooling airflow thrown out by the first cooling fan and the second cooling fan, thereby concentrating the heat dissipation of the air duct plate and discharging it quickly and directionally through the first air outlet and the second air outlet, but also can make the cooling airflow in the first cooling air duct and the second cooling air duct better driven by the first cooling fan and the second cooling fan after entering the first air guide shroud and the second air guide shroud through the first air outlet and the second air outlet, so as to improve the flow speed of the cooling airflow in the body, thereby improving the heat dissipation efficiency and heat dissipation effect of the body.

[0005] In an optional embodiment, the first vent is adapted to be located above the second vent. The first vent is provided with a first guiding structure for guiding the airflow from the first vent upwards and / or to both sides, and the second vent is provided with a second guiding structure for guiding the airflow from the second vent to both sides. By providing the first guiding structure and the second guiding structure at the first vent and the second vent respectively, the airflow from the first vent and the second vent is guided in different directions on the machine body. This not only avoids mutual interference between the first vent and the second vent during airflow discharge, thus preventing turbulence, but also prevents the airflow from directly flowing out of the first vent and the second vent, thus avoiding overheating of the rear wall of the machine body. This effectively ensures the heat dissipation efficiency and effect of the machine body.

[0006] In an optional embodiment, the first cooking cavity is provided with a first hot air vent, which is connected to the first air guide or the first ventilation opening via a first air outlet channel; the second cooking cavity is provided with a second hot air vent, which is connected to the second air guide or the second ventilation opening via a second air outlet channel. By respectively providing the first air outlet channel and the second air outlet channel connecting the first cooking cavity and the first ventilation opening or the first air guide, and the second cooking cavity and the second ventilation opening or the second air guide, the mixing of hot and cold air from the first cooking cavity and the second cooking cavity can be achieved, effectively reducing the temperature of the airflow discharged from the first ventilation opening and the second ventilation opening, thereby avoiding burns to the user and / or overheating of the rear wall of the machine body, effectively improving user safety.

[0007] In an optional embodiment, a first core assembly including the first air guide shroud is provided above the first cooking cavity. The first core assembly and the outer shell of the air fryer are adapted to form a portion of the first heat dissipation air duct. A first drive motor is provided on the first core assembly. The first drive motor extends at least partially into the first air guide shroud and is driven and connected to the first cooling fan. By providing the first core assembly above the first cooking cavity and placing the first drive motor on the first core assembly, the air fryer can not only use the first heat dissipation air duct or the cooling air flow in the first heat dissipation air duct or the first heat dissipation air duct and the second heat dissipation air duct to dissipate heat on the first drive motor when cooking food using the first cooking cavity and the second cooking cavity or using the first cooking cavity alone, but also allow the air fryer to draw external cold air from the first vent into the first heat dissipation air duct to dissipate heat on the first drive motor when cooking food using the second cooking cavity alone. This reduces the impact of high-temperature heat transfer in the first cooking cavity and / or the second cooking cavity on the first drive motor, effectively ensuring the performance stability and safety of the first drive motor.

[0008] A second core assembly, including a second air guide shroud, is provided above the second cooking cavity. The second core assembly and the outer casing are adapted to form a partial second heat dissipation duct. A second drive motor is provided on the second core assembly, and the second drive motor extends at least partially into the second air guide shroud and is driven and connected to the second cooling fan. By providing the second core assembly above the second cooking cavity and mounting the second drive motor on the second core assembly, the air fryer can not only dissipate heat on the second drive motor using the second heat dissipation duct or the cooling airflow within the first and second heat dissipation ducts when heating food using the first and second cooking cavities or using the second cooking cavity alone, but also allow the air fryer to draw external cold air from the second vent into the second heat dissipation duct to dissipate heat on the second drive motor when cooking food using the first cooking cavity alone. This reduces the impact of high-temperature heat transfer within the first and / or second cooking cavities on the second drive motor, effectively ensuring the performance stability and safety of the second drive motor.

[0009] In one optional embodiment, the first air vent is adapted to surround the first drive motor; the second air vent is adapted to surround the second drive motor. By arranging the first air vent and the second air vent around the first drive motor and the second drive motor respectively, the cooling airflow in the first and second cooling air ducts can better dissipate heat from the first and second drive motors when entering the first and second air guide shrouds, effectively improving the heat dissipation efficiency and effect of the first and second drive motors.

[0010] In an optional embodiment, the first cooling fan and / or the second cooling fan includes a second body and second blades spaced apart on the second body and extending upward, the second blades being disposed around the outside of the first drive motor and / or the second drive motor. By arranging the second blades around the first drive motor and / or the second drive motor, the first cooling fan and / or the second cooling fan can better dissipate heat from the first drive motor and / or the second drive motor when rotating, effectively improving heat dissipation efficiency and effect.

[0011] In an optional embodiment, the second body has a downwardly recessed third recess, and the first drive motor and / or the second drive motor are at least partially located within the third recess. By providing the third recess on the second body and at least partially housing the first drive motor and / or the second drive motor within the third recess, not only can the height of the unit be reduced, thereby lowering the center of gravity of the air fryer and making it more stable during operation, but the structure of the air fryer can also be made more compact, effectively reducing the overall volume of the air fryer and thus reducing its space occupation for easier storage and transportation.

[0012] In an optional embodiment, the top of the first cooking cavity and / or the second cooking cavity is provided with an air duct plate, and a heat circulation fan is provided on the inner side of the air duct plate. The middle part of the air duct plate is provided with a first protrusion protruding into the cooking cavity. The heat circulation fan includes a first body and first blades distributed circumferentially on the first body and extending into the first cooking cavity. The area corresponding to the first protrusion on the first body is provided with a second recessed part that is recessed into the cooking cavity. By providing the first protrusion protruding into the cooking cavity in the middle of the air duct plate and providing the second recessed part matching the first protrusion on the heat circulation fan, the height of the air fryer can be reduced, the overall volume of the air fryer can be reduced, thereby reducing the space occupied by the air fryer, facilitating storage and transportation, and effectively improving the user experience.

[0013] In an optional embodiment, the projections of the first protrusion and the second recess on their axes at least partially coincide. By setting the projections of the first protrusion and the second recess on their axes to at least partially coincide, the air duct plate and the air duct plate can better cooperate with the heat circulation fan, thereby effectively reducing the overall volume and space occupation of the air fryer for easier storage and transportation.

[0014] In one optional embodiment, a heating element is arranged around the outside of the hot air circulating fan, and the projection of the heating element on the axis of the hot air circulating fan at least partially coincides with that of the hot air circulating fan. By arranging the heating element around the outside of the hot air circulating fan and setting the hot air circulating fan to at least partially coincide with the projection of the heating element on the axis of the hot air circulating fan, the structure of the air fryer can be made more compact, effectively reducing the overall volume of the air fryer. It also allows the heating element to better cooperate with the hot air circulating fan, thereby heating the circulating airflow driven by the hot air circulating fan, effectively improving the cooking efficiency and cooking effect of the air fryer.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] This application, by setting a first cooking chamber and a second cooking chamber within the body of the air fryer and arranging them vertically at intervals, not only allows the air fryer to cook multiple foods simultaneously, effectively improving cooking efficiency, but also reduces the lateral volume of the air fryer, thereby reducing its space occupancy for easier storage and transportation. Simultaneously, by setting interconnected first and second heat dissipation ducts within the body, the air fryer can utilize the cooling airflow within the first and second heat dissipation ducts to dissipate heat from the first and second cooking chambers respectively, effectively improving heat dissipation efficiency and effect. Furthermore, regardless of whether food is cooked in the first or / or second cooking chamber, the air fryer can achieve overall heat dissipation, effectively ensuring the performance stability and safety of the air fryer. Furthermore, by covering the outside of the first cooling fan and the second cooling fan with the first air guide shroud and the second air guide shroud respectively, and setting the first air outlet and the second air outlet to correspond to the middle air intake area of ​​the first cooling fan and the second cooling fan respectively, not only can the first air guide shroud and the second air guide shroud block, collect and guide the cooling cold air thrown out by the first cooling fan and the second cooling fan, thereby concentrating the heat dissipation of the air duct plate and discharging it quickly and directionally through the first air outlet and the second air outlet, but also can make the cooling cold air in the first cooling air duct and the second cooling air duct be better driven by the first cooling fan and the second cooling fan after entering the first air guide shroud and the second air guide shroud through the first air outlet and the second air outlet, so as to improve the flow speed of the cooling cold air in the body, thereby improving the heat dissipation efficiency and heat dissipation effect of the body.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, 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 terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" 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, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0028] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0029] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., may be used here to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.

The term "a" should not be construed as a limitation on 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 a limitation on the scope of protection of this utility model.

[0031] Appendix Figure 1 To be continued Figure 8The diagram shows a schematic of a dual-core air fryer with good heat dissipation provided by this utility model. The air fryer includes a body 10 and a cooking chamber 11 disposed within the body 10. The cooking chamber 11 is equipped with a hot air system 20 for providing hot air to the cooking chamber 11, which can heat the food in the cooking chamber 11. The cooking chamber 11 is provided with a heat dissipation duct 12 and a heat dissipation system 30 connected to the heat dissipation duct 12. The heat dissipation system 30 includes a core assembly 31 disposed above the duct plate 21, a drive motor 32 disposed on the core assembly 31, and a cooling fan 33 disposed between the core assembly 31 and the duct plate 21. The cooling fan 33 is adapted to be driven and connected to the drive motor 32. By driving the cooling fan 33 to rotate, external cold air can be drawn into the heat dissipation duct 12 to dissipate heat from the body 10, effectively ensuring the performance stability and safety of the air fryer.

[0032] Furthermore, such as Figures 1 to 5As shown, the cooking cavity 11 includes a first cooking cavity 111 and a second cooking cavity 112 arranged vertically at intervals, and the heat dissipation duct 12 includes a first heat dissipation duct 121 and a second heat dissipation duct 122 arranged vertically and communicating with each other. The first heat dissipation duct 121 and the second heat dissipation duct 122 are adapted to be arranged around at least a portion of the first cooking cavity 111 and the second cooking cavity 112, respectively. By providing the first cooking cavity 111 and the second cooking cavity 112 within the body 10, and arranging the first cooking cavity 111 and the second cooking cavity 112 vertically spaced apart, the air fryer can not only cook multiple foods simultaneously, effectively improving cooking efficiency, but also reduce the lateral volume of the air fryer, thereby reducing its space occupation for easier storage and transportation. Simultaneously, by providing the first heat dissipation duct 121 and the second heat dissipation duct 122 surrounding at least a portion of the first cooking cavity 111 and the second cooking cavity 112 respectively, the air fryer can utilize the cooling airflow within the first heat dissipation duct 121 and the second heat dissipation duct 122 to cool the first cooking cavity 111 and the second cooking cavity 112 respectively. The second cooking chamber 112 provides heat dissipation, effectively improving heat dissipation efficiency and effect. It also ensures that the air fryer can dissipate heat as a whole, regardless of whether food is cooked using the first cooking chamber 111 or the second cooking chamber 112, thus guaranteeing the air fryer's heat dissipation efficiency and effect, and consequently ensuring the air fryer's performance stability and user safety. Furthermore, by arranging the first and second heat dissipation ducts 121 and 122 vertically at intervals, the airflow path of the first and second heat dissipation ducts 121 and 122 is simplified, allowing external cold air to flow rapidly after entering them, effectively improving the cold air circulation efficiency and heat dissipation efficiency within the body 10.

[0033] like Figures 1 to 8As shown, in an optional embodiment, a vent 13 is provided on the rear side of the body 10, the vent 13 including a first vent 131 and a second vent 132; a first air guide shroud 3111 is provided above the first cooking cavity 111, one side of the first air guide shroud 3111 is adapted to extend to the rear side of the body 10 and communicate with the first vent 131 on the rear side wall of the body 10, a first air vent 3112 communicating with the first heat dissipation air duct 121 is provided above the first air guide shroud 3111, and a first cooling fan 331 is provided in the first air guide shroud 3111. The central air intake area of ​​the cooling fan 331 is adapted to correspond to the first air vent 3112; a second air guide shroud 3121 is provided above the second cooking cavity 112, one side of the second air guide shroud 3121 is adapted to extend to the rear side of the body 10 and communicate with the second ventilation vent 132 on the rear side wall of the body 10, a second air vent 3122 is provided above the second air guide shroud 3121 and communicates with the second heat dissipation air duct 122, a second cooling fan 332 is provided in the second air guide shroud 3121, and the central air intake area of ​​the second cooling fan 332 corresponds to the second air vent 3122.In the air fryer, since the first cooling fan 331 and the second cooling fan 332 typically have central air intake and peripheral air exhaust, and since the heat circulation fan 22 and the heating element 23 are typically located near the air duct plate 21, the temperature of the air duct plate 21 is usually relatively high. By covering the first cooling fan 331 and the second cooling fan 332 with the first air guide shroud 211 and the second air guide shroud 213 respectively, the cooling airflow ejected by the first cooling fan 331 and the second cooling fan 332 can be blocked and collected using the first air guide shroud 3111 and the second air guide shroud 3121. This concentrates heat dissipation on the air duct plate 21, effectively improving the heat dissipation efficiency and effect of the first cooling fan 331 and the second cooling fan 332. It also directs the flow of the cold air ejected by the first cooling fan 331 and the second cooling fan 332, preventing the cold air ejected by the first cooling fan 331 and the second cooling fan 332 from affecting the cold air about to enter the first cooling fan 331 and the second cooling fan 332, thus avoiding turbulence and effectively ensuring the cold air circulation efficiency and heat dissipation efficiency of the air fryer. Simultaneously, by connecting the first cooling air duct 121 and... The first air vent 3112 and the second air vent 3122 of the second heat dissipation air duct 122 are respectively configured to correspond to the middle air intake areas of the first cooling fan 331 and the second cooling fan 332. This allows the cooling airflow within the first heat dissipation air duct 121 and the second heat dissipation air duct 122 to be better driven by the first cooling fan 331 and the second cooling fan 332 after entering the first air guide shroud 3111 and the second air guide shroud 3121 through the first air vent 3112 and the second air guide shroud 3122, thereby improving the flow of cooling airflow within the first heat dissipation air duct 121 and the second heat dissipation air duct 122. The air fryer improves heat dissipation efficiency and effectiveness by increasing the speed of heat dissipation. Furthermore, by placing the first vent 131 and the second vent 132 at the rear of the air fryer and connecting them to the first heat dissipation duct 121 and the second heat dissipation duct 122 respectively, not only can the first vent 131 and the second vent 132 be concealed to enhance the overall aesthetics of the air fryer, but the first heat dissipation duct 121 and the second heat dissipation duct 122 can also be independently vented, allowing the cool airflow carrying heat within the air fryer to be quickly dispersed and discharged, thereby effectively improving the heat dissipation efficiency and effectiveness of the air fryer.

[0034] like Figures 1 to 4As shown, in an optional embodiment, the body 10 is provided with a connecting port 14 that connects to the heat dissipation duct 12. The connecting port 14 includes a first connecting port 141 and a second connecting port 142 respectively located at the top and bottom of the body 10. The first connecting port 141 and the second connecting port 142 are adapted to connect to the first heat dissipation duct 121 and the second heat dissipation duct 122 respectively. By providing the first connecting port 141 and the second connecting port 142 respectively connecting to the first heat dissipation duct 121 and the second heat dissipation duct 122 on the body 10, not only can the air fryer quickly draw in external cold air into the first heat dissipation duct 121 and the second heat dissipation duct 122 to dissipate heat from the body 10, but it also ensures that the air intake of the first heat dissipation duct 121 and the second heat dissipation duct 122 does not interfere with each other, effectively improving the air intake efficiency of the first heat dissipation duct 121 and the second heat dissipation duct 122, thereby improving the heat dissipation efficiency of the air fryer.

[0035] like Figure 2 As shown, in an optional embodiment, when both the first cooking chamber 111 and the second cooking chamber 112 of the air fryer are working, the first cooling fan 331 and the second cooling fan 332 are also working. At this time, external cold air outside the body 10 can enter the first cooling duct 121 and the second cooling duct 122 through the first connecting port 141 and the second connecting port 142 respectively, and is discharged through the first vent 131 and the second vent 132 respectively. By utilizing the first connecting port 141 and the second connecting port 142 for air intake and the first vent 131 and the second vent 132 for air exhaust, not only can the air intake speed of the first cooling duct 121 and the second cooling duct 122 be effectively increased, but also the rapid air exhaust of the first cooling duct 121 and the second cooling duct 122 can be achieved, effectively improving the cold air circulation efficiency inside the air fryer, thereby improving the heat dissipation effect of the air fryer.

[0036] like Figure 3As shown, in an optional embodiment, when the first cooking chamber 111 of the air fryer is working and the second cooking chamber 112 is not working, the first cooling fan 331 is working and the second cooling fan 332 is not working. At this time, the external cold air outside the body 10 can not only enter the first cooling duct 121 through the first connecting port 141 and be discharged through the first vent 131, but also enter the second cooling duct 122 through the second connecting port 142 and the second vent 132, and then flow through the first cooling duct 121 and be discharged through the first vent 131. By utilizing the first connecting port 141, the second connecting port 142, and the second vent 132 for air intake and the first vent 131 for air exhaust, the air intake speed and volume of the body 10 can be effectively increased, thereby improving the heat dissipation efficiency and effect of the body 10. Furthermore, when the body 10 receives air through the second connecting port 142 and the second vent 132, the cooling airflow within the second heat dissipation duct 122 can dissipate heat to the non-working areas of the body 10, thus preventing high-temperature heat transfer from damaging the circuits, electronic components, and other electrical devices in the non-working areas of the body 10, and effectively ensuring the performance stability of the air fryer.

[0037] like Figure 4 As shown, in an optional embodiment, when the first cooking chamber 111 of the air fryer is not working and the second cooking chamber 112 is working, the first cooling fan 141 is not working and the second cooling fan 142 is working. At this time, the external cold air outside the body 10 can not only enter the second cooling duct 122 through the second connecting port 142 and be discharged through the second vent 132, but also enter the first cooling duct 121 through the first connecting port 141 and the first vent 131, and then flow through the second cooling duct 122 and be discharged through the second vent 132. By utilizing the first connecting port 141, the first vent 131, and the second connecting port 142 for air intake and the second vent 132 for air exhaust, the air intake speed and volume of the body 10 can be effectively increased, thereby improving the heat dissipation efficiency and effect of the body 10. Furthermore, when the body 10 intakes air through the first connecting port 141 and the first vent 131, the cooling airflow within the first heat dissipation duct 121 can dissipate heat to the non-working areas of the body 10, thus preventing high-temperature heat transfer from damaging the circuits, electronic components, and other electrical devices in the non-working areas of the body 10, and effectively ensuring the performance stability of the air fryer.

[0038] like Figures 1 to 6As shown, in an optional embodiment, the first vent 131 is adapted to be located above the second vent 132. The first vent 131 is provided with a first guide structure 133 for guiding the airflow from the first vent 131 upwards and / or to the left and right sides. The second vent 132 is provided with a second guide structure 134 for guiding the airflow from the second vent 132 to the left and / or right sides. By providing the first guide structure 133 and the second guide structure 134 at the first vent 131 and the second vent 132 respectively, the airflow from the first vent 131 and the second vent 132 is guided to different directions of the body 10. This not only avoids mutual interference between the first vent 131 and the second vent 132 when discharging air, thus preventing turbulence, but also prevents the airflow from directly flowing out of the first vent 131 and the second vent 132, thus avoiding overheating of the rear wall of the body 10. This effectively ensures the heat dissipation efficiency and effect of the body 10.

[0039] like Figures 1 to 5 As shown, in an optional embodiment, the body 10 is provided with an air outlet 40, which includes a first air outlet 41 and a second air outlet 42. The first cooking cavity 111 is provided with a first hot air vent 1111, which is adapted to communicate with the first air guide hood 3111 or the first ventilation vent 131 through the first air outlet 41. The second cooking cavity 112 is provided with a second hot air vent 1121, which is adapted to communicate with the second air guide hood 3121 or the second ventilation vent 132 through the second air outlet 42. By providing the first air outlet channel 41 and the second air outlet channel 42 within the body 10, respectively connecting the first cooking cavity 111 with the first vent 131 or the first air guide hood 221, and the second cooking cavity 112 with the second vent 132 or the second air guide hood 3121, the mixing of hot and cold air from the first cooking cavity 111 and the second cooking cavity 112 can be achieved. This effectively reduces the temperature of the airflow discharged from the first vent 131 and the second vent 132, thereby avoiding burns to the user and / or overheating of the rear wall of the body 10, and effectively improving user safety.

[0040] like Figures 1 to 4As shown, in an optional embodiment, a first core assembly 311 including the first air guide shroud 3111 is provided above the first cooking cavity 11. The first core assembly 311 and the outer shell of the body 10 are adapted to form a portion of the first heat dissipation air duct 121. A first drive motor 321 is provided on the first core assembly 311. The first drive motor 321 extends at least partially into the first air guide shroud 3111 and is driven and connected to the first heat dissipation fan 331. By setting the first core assembly 311 above the first cooking cavity 111 and mounting the first drive motor 321 on the first core assembly 311, the air fryer can utilize the cooling airflow within the first heat dissipation duct 121 or the first heat dissipation duct 121 and the second heat dissipation duct 122 to dissipate heat from the first drive motor 321 when cooking food using the first cooking cavity 111 and the second cooking cavity 112 or using the first cooking cavity 111 alone. Furthermore, when cooking food using the second cooking cavity 112 alone, the air fryer can use the first cooling fan 331 to draw external cold air from the first vent 131 into the first heat dissipation duct 121 to dissipate heat from the first drive motor 321, thereby reducing the impact of high-temperature heat transfer within the first cooking cavity 111 and / or the second cooking cavity 112 on the first drive motor 321 and effectively ensuring the performance stability and safety of the first drive motor 321.

[0041] like Figures 1 to 4As shown, a second core assembly 312 including a second air guide shroud 3121 is provided above the second cooking cavity 112. The second core assembly 312 and the outer shell of the body 10 are adapted to form a partial second heat dissipation air duct 122. A second drive motor 322 is provided on the second core assembly 312. The second drive motor 322 extends at least partially into the second air guide shroud 3121 and is driven and connected to the second heat dissipation fan 332. By setting the second core assembly 312 above the second cooking cavity 112 and mounting the second drive motor 322 on the second core assembly 312, the air fryer can not only use the cooling airflow in the second heat dissipation duct 122 or the first heat dissipation duct 121 and the second heat dissipation duct 122 to dissipate heat from the second drive motor 322 when heating food using the first cooking cavity 111 and the second cooking cavity 112 or using the second cooking cavity 112 alone, but also allow the air fryer to use the second cooling fan 332 to draw external cold air from the second vent 132 into the second heat dissipation duct 122 to dissipate heat from the second drive motor 322 when cooking food using the first cooking cavity 111 alone. This reduces the impact of high-temperature heat transfer in the first cooking cavity 111 and / or the second cooking cavity 112 on the second drive motor 322, effectively ensuring the performance stability and safety of the second drive motor 322.

[0042] like Figures 1 to 4 As shown, in an optional embodiment, the first air vent 3112 is adapted to surround the first drive motor 321; the second air vent 3122 is adapted to surround the second drive motor 322. By arranging the first air vent 3112 and the second air vent 3122 around the first drive motor 321 and the second drive motor 322 respectively, the cooling airflow in the first cooling duct 121 and the second cooling duct 122 can better dissipate heat from the first drive motor 321 and the second drive motor 322 when it enters the first air guide shroud 3111 and the second air guide shroud 3121, effectively improving the heat dissipation efficiency and effect of the first drive motor 321 and the second drive motor 322.

[0043] like Figures 1 to 4As shown, in one optional embodiment, the first cooling fan 331 and / or the second cooling fan 332 includes a second body and second blades spaced apart on the second body and extending upward. The second blades are arranged around the outside of the first drive motor 321 and the second drive motor 322. By arranging the second blades around the first drive motor 321 and / or the second drive motor 322, the first cooling fan 331 and the second cooling fan 332 can better dissipate heat from the first drive motor 321 and the second drive motor 322 when rotating, effectively improving heat dissipation efficiency and effect. Furthermore, in another optional embodiment, the second blades can be arranged only around the first drive motor or the second drive motor. This also allows the first cooling fan 331 or the second cooling fan 332 to better dissipate heat from the first drive motor 321 or the second drive motor 322 when rotating, effectively improving the heat dissipation efficiency and effect of the first cooling fan 331 or the second cooling fan 332.

[0044] like Figures 1 to 4 As shown, in one optional embodiment, the second main body has a downwardly recessed third recess 333, and the first drive motor 321 and the second drive motor 322 are at least partially located within the third recess 333. By providing the third recess 333 on the second main body and at least partially housing the first drive motor 321 and the second drive motor 322 within the third recess 333, not only can the height of the body 10 be reduced, thereby lowering the center of gravity of the air fryer and making the air fryer more stable during operation, but the structure of the air fryer can also be made more compact, effectively reducing the overall volume of the air fryer and thus reducing the space occupied by the air fryer for easier storage and transportation. Furthermore, in another optional embodiment, only at least a portion of the first drive motor 321 or the second drive motor 322 may be located within the third recess 333, thus achieving the same effect.

[0045] like Figures 1 to 5As shown, in an optional embodiment, the hot air system 20 includes an air duct plate 21 disposed at the top of the first cooking cavity 111 and / or the second cooking cavity 112, and a hot air circulation fan 22 disposed inside the air duct plate 21 to generate circulating airflow. The air duct plate 21 has a first protrusion 211 protruding into the first cooking cavity 11 at its center. The hot air circulation fan 22 includes a first body and first blades distributed circumferentially on the first body and extending into the first cooking cavity. A second recess 221, recessed into the cooking cavity 11, is provided in the area corresponding to the first protrusion 211 on the first body. By providing the first protrusion 211 protruding into the cooking cavity 11 at the center of the air duct plate 21 and the second recess 221 matching the first protrusion 211 on the hot air circulation fan 22, the height of the air fryer can be reduced, the overall volume of the air fryer can be decreased, thereby reducing the space occupied by the air fryer, facilitating storage and transportation, and effectively improving the user experience.

[0046] like Figures 1 to 4 As shown, in an optional embodiment, the projections of the first protrusion 211 and the second recess 221 on their axes at least partially overlap. By setting the projections of the first protrusion 211 and the second recess 221 on their axes at least partially overlap, the air duct plate 21 and the air duct plate 221 can better cooperate with the heat circulation fan 22, thereby effectively reducing the overall volume and space occupation of the air fryer for easier storage and transportation.

[0047] like Figures 1 to 4 As shown, in an optional embodiment, the hot air system 20 further includes a heating element 23 surrounding the outside of the hot air circulation fan 22, the heating element 23 at least partially coinciding with the projection of the hot air circulation fan 22 on its axis. By surrounding the outside of the hot air circulation fan 22 with the projection of the heating element 23 on its axis, the air fryer can be made more compact, effectively reducing its overall volume. Furthermore, the heating element 23 can better cooperate with the hot air circulation fan 22 to heat the circulating airflow driven by the hot air circulation fan 22, effectively improving the cooking efficiency and effect of the air fryer.
