Description

Technical Field

[0001] This utility model relates to the field of air fryer technology, and more specifically, to an air fryer. Background Technology

[0002] Currently, air fryers have gradually become the preferred kitchen appliance for healthy eating among modern people. Among the related technologies, some dual-cavity air fryers use top-mounted fans that blow air from top to bottom. Each cavity requires an independent motor, which increases costs. At the same time, there are more assembled parts, resulting in lower production efficiency. Utility Model Content

[0003] This invention aims to at least solve the technical problem of the large number of assembly parts in existing dual-cavity air fryers, which exists in the prior art or related technologies.

[0004] In view of this, an embodiment of the present invention provides an air fryer.

[0005] To achieve the above objectives, an embodiment of the present invention provides an air fryer, comprising: a cooking body, the cooking body including at least two cooking chambers spaced apart along a first direction; a first heating element disposed in the cooking chambers; a driving chamber disposed between two adjacent cooking chambers, the driving chamber containing a driving motor, the driving motor including a driving shaft extending along the first direction; and at least two fan blades disposed on one side of one of the two adjacent cooking chambers facing the other, the two ends of the driving shaft being drively connected to the at least two fan blades, the fan blades being used to drive the airflow within the cooking chambers.

[0006] The air fryer according to this utility model mainly includes a cooking body, a first heating element, a drive cavity, and a fan. The cooking body comprises two or more cooking cavities. By arranging these cavities at intervals along a first direction, the internal space of the cooking body can be divided into multiple independent spaces, allowing for the simultaneous cooking of two different foods. This reduces interference between ingredients, enables independent operation of both cavities, and saves time and electricity. A drive cavity is positioned between two adjacent cooking cavities, housing a drive motor that provides power without occupying excessive space. The drive motor, via a drive shaft, rotates the fan, allowing hot air to circulate within the cooking cavities, creating a hot air circulation that quickly and evenly distributes heat to the food surface, ensuring rapid oil removal and a crispy exterior with a tender interior.

[0007] Based on this, two or more fan blades are installed and positioned within the cooking cavity, specifically facing one adjacent cooking cavity. The two ends of the drive shaft are connected to the fan blades. The arrangement of each fan blade and its connection to the motor ensures stable airflow, preventing uneven airflow or overheating in any particular cavity.

[0008] Each cooking chamber is equipped with a primary heating element, providing the high-temperature heat source required by the air fryer to ensure that food is heated quickly and evenly. Each cooking chamber is independently equipped with a primary heating element, which can provide the required cooking temperature for each chamber. For example, some foods require a high-temperature frying effect, while others require a low-temperature slow frying.

[0009] It should be emphasized that in this solution, the driving cavity and the cooking cavity are arranged along the first direction. The two adjacent cooking cavities are not in direct contact, but an independent driving cavity is set between them, thereby ensuring the distance between the two cooking cavities, reducing mutual interference during the cooking process, and maintaining the independence of the cooking of ingredients in the cooking cavity.

[0010] Furthermore, by placing the drive motor between the two cooking cavities, space is utilized more efficiently. Compared to the traditional design where each cavity has its own independent motor, this layout allows for greater integration of the motor and fan drive system, saving space and making the overall device more compact.

[0011] In some technical solutions, optionally, it also includes: at least two wind hood structures, the wind hood structures are located on the side of the cooking cavity facing another adjacent cooking cavity, and the wind hood structures are connected to the cooking cavity.

[0012] In this technical solution, two or more fan hood structures connected to the cooking cavity are set up on the cooking cavity, specifically on the side of the cooking cavity facing another adjacent cooking cavity. The function of the fan hood structure is to optimize the hot air circulation within the cooking cavity, so that the hot air generated by the fan blades driven by a single motor can flow evenly and efficiently inside the cooking cavity, thereby ensuring that the food is heated evenly and improving the air frying effect.

[0013] The fan hood structure is located on the side of the cooking cavity facing the adjacent cooking cavity. The fan hood structure is directly connected to the cooking cavity, allowing the air generated by the fan blades to circulate within the cooking cavity under the action of the fan hood structure. The fan hood structure covers the rear of the fan blades, allowing the hot air blown out by the fan blades to be guided by the fan hood, thus forming a more reasonable circulation path within the cooking cavity.

[0014] In some technical solutions, optionally, a second heating element is also included, disposed on the shroud structure; wherein the second heating element is connected in series with the first heating element.

[0015] In this technical solution, by setting a second heating element on the fan hood structure and connecting the second heating element in series with the first heating element, the hot air circulation system is further optimized, thereby improving cooking efficiency and heat energy utilization.

[0016] Since the fan blades are installed inside the cooking cavity, the drive motor drives the fan blades to rotate at high speed. The second heating element is located on the fan shroud structure. Air is drawn into the fan shroud by the fan blades and heated by the second heating element, which raises the initial air temperature.

[0017] Because the hood structure can control the airflow path, hot air enters the cooking cavity in a predetermined direction. After entering the cooking cavity, the air is further heated by the first heating element, reaching a higher temperature and achieving the final frying / grilling effect.

[0018] The first heating element is typically located at the top, side, or bottom of the cooking cavity, connected in series with the second heating element. This ensures continuous circulation of hot air throughout the cavity, preventing insufficient temperature from affecting cooking results. The air passing through the first heating element is further guided and recirculated by the rotation of the fan blades, ensuring even heat distribution throughout the cavity. Because the air circulates repeatedly and is heated by both heating elements, every part of the food is heated evenly, avoiding the localized overheating or temperature dead zones common in traditional air fryers.

[0019] The first and second heating elements are connected in series to form a complete heating system. This means that the two heating elements share the same current, ensuring more stable power utilization.

[0020] In some technical solutions, optionally, the cooking cavity includes multiple walls, and the first heating element and the second heating element are located on at least two walls of the cooking cavity.

[0021] In this technical solution, the first and second heating elements are respectively arranged on multiple walls of the cooking cavity, forming a more balanced hot air circulation system and optimizing the overall cooking effect. The first heating element can be located at the top and / or bottom of the cooking cavity, serving as the main heat source to initially heat the air and provide the basic temperature conditions for the hot air system. The second heating element can be arranged on the fan shroud structure and connected in series with the first heating element, allowing the hot air to be further heated, reducing temperature attenuation, and improving the quality of the hot air.

[0022] In some technical solutions, optionally, the first heating element includes multiple heating parts, and at least two heating parts are provided in the cooking cavity and spaced apart in a second direction; wherein, the first direction is perpendicular to the second direction.

[0023] In this technical solution, the first heating element comprises multiple heating sections, which are not a single heating body but are distributed throughout the cooking cavity to form a layered heating system. Each heating section operates independently but collectively contributes to the airflow and heating within the cooking cavity.

[0024] The perpendicularity of the first and second directions helps to enhance the change in airflow path, thereby improving air circulation efficiency and allowing hot air to fully reach every corner of the food.

[0025] With multiple heating elements spaced apart, hot air doesn't concentrate in one area but covers the entire cavity, ensuring food is heated evenly from all angles. After being heated by the multiple heating elements, the air forms a more efficient circulation path. Because the heating elements are spaced apart in a second direction, hot air can flow in multiple directions within the cavity and, through a relatively large heat radiation area, allow every part of the cavity to effectively absorb heat.

[0026] In some technical solutions, optionally, an oil storage tank is also included, located inside the cooking body. The oil storage tank is located on one side of the cooking cavity in the direction of gravity, and the oil storage tank is located on the side of the cooking cavity facing the driving cavity; the direction of gravity is not parallel to the first direction.

[0027] In this technical solution, by placing the oil collection tank inside the cooking unit, the oil can be automatically collected during cooking without the need for an external container. Furthermore, the built-in design prevents the oil collection tank from being contaminated or spilled from external factors, maintaining its cleanliness.

[0028] By restricting the oil storage tank to one side of the cooking cavity in the direction of gravity, the oil will naturally flow to the oil storage tank, thus making full use of gravity to guide the oil collection.

[0029] It should be emphasized that in this solution, the multiple cooking cavities are arranged at intervals along the first direction, and the oil storage tank is set on one side of the cooking cavity in the direction of gravity. Since the direction of gravity and the first direction are not parallel, it ensures that the oil flows smoothly from the cooking cavity into the oil storage tank.

[0030] In some technical solutions, optionally, an oil receiving tray is also included, which is located inside the cooking body and is connected to the oil storage tank; wherein the oil receiving tray is located on one side of the oil storage tank in the direction of gravity, and in the first direction the oil receiving tray is located between two adjacent cooking cavities.

[0031] In this technical solution, an oil receiving tray is installed inside the cooking unit. Working in conjunction with an oil storage tank, it receives and stores oil flowing from different cooking cavities. Because the oil receiving tray is located on the gravity-fed side of the oil storage tank, the oil flows naturally into it without the need for additional mechanical pumps or manual intervention. The natural force of gravity ensures smoother oil flow and prevents oil from accumulating in hard-to-clean areas.

[0032] It should be emphasized that, since the multiple cooking cavities are spaced apart, the oil drip tray can be placed between two adjacent cooking cavities to further utilize the empty space between the two adjacent cavities and reduce the overall size of the equipment in the first direction.

[0033] In some technical solutions, the drive motor optionally includes: a motor housing connected to the side wall of the hood structure away from the cooking cavity, and a drive shaft passing through two adjacent hood structures.

[0034] In this technical solution, the drive motor includes a drive shaft and a motor housing. The motor housing is connected to the fan shroud structure and is located on the side wall of the fan shroud structure away from the cooking cavity. The drive shaft passes through two adjacent fan shroud structures, enabling the motor to simultaneously drive the rotation of two fan blades. The fan blades distribute power to the two fan blades through the extension of the drive shaft, ensuring good airflow and circulation within the two cooking cavities.

[0035] By using a single motor connected to two fan blades via a drive shaft to achieve dual-chamber airflow, the space-saving design is significantly reduced, as is the number of motors required, thereby lowering production costs. This single-motor, dual-fan design eliminates the complex structure that would otherwise require multiple motors and drive units, making the equipment simpler and easier to maintain, further reducing failure rates and maintenance costs.

[0036] By connecting the motor housing to the fan structure, away from the high-temperature cooking cavity, the possibility of motor failure is reduced, and the negative impact of temperature on motor life is minimized.

[0037] In some technical solutions, the solution may optionally include: a heat dissipation fan blade, which is sleeved outside the drive shaft and located inside the drive cavity, and the drive shaft rotates to drive the heat dissipation fan blade to rotate.

[0038] In this technical solution, cooling fan blades are installed inside the drive cavity. When the motor starts, the drive shaft rotates, causing the cooling fan blades to rotate as well, helping to dissipate heat from the drive cavity and preventing the motor from overheating. The cooling fan blades are designed to be sleeved outside the drive shaft and rotate synchronously with it. The cooling fan blades generate airflow as the motor rotates, thereby effectively dissipating heat from the motor.

[0039] The cooling fan, driven by the rotation of the drive shaft, circulates air, quickly dissipating the heat generated by the motor and preventing overheating-related malfunctions during prolonged operation. It's understandable that the cooling fan's function extends beyond simply cooling the motor; it also reduces damage to motor components from overheating, improves long-term motor stability, and extends the equipment's lifespan.

[0040] In some technical solutions, the system may optionally include an air inlet located on the wall of the drive cavity, which is connected to the cooking cavity.

[0041] In this technical solution, an air inlet is provided on the wall of the drive cavity. When a single motor drives multiple fan blades, the air inlet can be located only on the wall of the drive cavity, allowing air to enter from one point. With the drive shaft driving the two fan blades on the left and right, air can be exited from multiple points, while also ensuring that the cooling fan blades dissipate heat from the drive motor. In other words, in this solution, the location of the air inlet is relatively simple, but it has stronger functionality. The air drawn into the drive cavity first undergoes heat exchange through the drive motor, initially increasing its temperature, before flowing into each cooking cavity. Under the action of the first and second heating elements, the temperature rise is further increased, reducing the temperature rise and improving cooking efficiency.

[0042] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention. Attached Figure Description

Detailed Implementation

[0047] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0049] The following reference Figure 1 and Figure 2 Some embodiments according to the present invention are described.

[0050] like Figure 1 and Figure 2 As shown, this embodiment provides an air fryer 100, mainly including a cooking body 102, a first heating element 104, a drive cavity 106, and a fan blade 110. The cooking body 102 includes two or more cooking cavities 1022. By arranging the multiple cooking cavities 1022 at intervals along a first direction, the internal space of the cooking body 102 can be divided into multiple independent spaces, allowing for the simultaneous cooking of two different foods, reducing interference between ingredients, and enabling independent operation of both cavities, saving time and power consumption. A drive cavity 106 is provided between two adjacent cooking cavities 1022, and a drive motor 108 is installed within the drive cavity 106, providing power support without occupying excessive space. The drive motor 108, via a drive shaft 1082, drives the rotation of the fan blade 110, allowing hot air to circulate within the cooking cavities 1022, forming a hot air circulation. This quickly and evenly distributes heat to the food surface, ensuring the air fryer 100 achieves rapid oil removal and a crispy exterior with a tender interior.

[0051] Based on this, two or more fan blades 110 are set and correspondingly positioned within the cooking cavity 1022, specifically facing one adjacent cooking cavity 1022. Both ends of the drive shaft 1082 are connected to the fan blades 110. The arrangement of each fan blade 110 and its connection to the motor ensures stable airflow, preventing uneven airflow or overheating in any cavity.

[0052] Each cooking cavity 1022 is equipped with a first heating element 104, which provides the high-temperature heat source required by the air fryer 100 to ensure that the food is heated quickly and evenly. Each cooking cavity 1022 is independently equipped with a first heating element 104, which can provide the required cooking temperature for each cavity. For example, some foods require a high-temperature frying effect, while others require a low-temperature slow frying.

[0053] The entire system uses a single drive motor 108 to support two or more cooking cavities 1022. By using a single motor to achieve hot air circulation in multiple cavities, not only are production costs saved, but the complexity of the product is also reduced. The design of multiple independent motors usually increases the manufacturing cost, size, and weight of the product, while this solution effectively solves these problems, making the product lighter and more cost-effective.

[0054] It should be emphasized that in this solution, the driving cavity 106 and the cooking cavity 1022 are arranged along the first direction. The two adjacent cooking cavities 1022 are not in direct contact, but an independent driving cavity 106 is set between them, thereby ensuring the distance between the two cooking cavities 1022, reducing mutual interference during the cooking process, and maintaining the independence of food cooking in the cooking cavity 1022.

[0055] Furthermore, by placing the drive motor 108 between the two cooking cavities 1022, space utilization is made more compact. Compared to the traditional design where each cavity is equipped with an independent motor, this layout allows for greater integration of the motor and the fan blade 110's transmission system, saving space and making the overall device more compact.

[0056] The drive motor 108 is located between the two chambers and can transmit power to the two fan blades 110 through a single transmission system (e.g., via a drive shaft or belt). This avoids the need for two independent motors and transmission systems in traditional designs, reducing the number of motors and the complexity of the transmission system, thereby reducing friction and mechanical noise caused by multiple motors and independent transmissions. At the same time, transmission efficiency is improved, the motor load is relatively lighter, and it maintains better stability and durability over long-term use.

[0057] Two or more fan hood structures 112 are connected to the cooking cavity 1022 and are respectively positioned on the side of the cooking cavity 1022 facing another adjacent cooking cavity 1022. The function of the fan hood structure 112 is to optimize the hot air circulation within the cooking cavity 1022, so that the hot air generated by the fan blade 110 driven by a single motor can flow evenly and efficiently inside the cooking cavity 1022, thereby ensuring uniform heating of the food and improving the air frying effect.

[0058] It is understandable that the fan shroud is used to restrict the direction of airflow, so that the hot air circulates along a designed path instead of flowing randomly, thereby improving the utilization rate of hot air and preventing hot air from escaping quickly after being ejected directly from the fan blade 110 area. Instead, it circulates fully within the cavity to ensure that the food surface is heated evenly.

[0059] The fan shroud structure 112 is located on the side of the cooking cavity 1022 facing the adjacent cooking cavity 1022. The fan shroud structure 112 is directly connected to the cooking cavity 1022, allowing the air generated by the rotation of the fan blade 110 to circulate within the cooking cavity 1022 under the action of the fan shroud structure 112. The fan shroud structure 112 covers the rear of the fan blade 110, allowing the hot air blown out by the fan blade 110 to be guided by the fan shroud, thereby forming a more reasonable circulation path within the cooking cavity 1022.

[0060] The fan shroud can serve as a convection shroud on the drive motor 108, allowing hot air to be blown out from the fan blade 110 and guided into the cooking cavity 1022 by the fan shroud.

[0061] Within two adjacent cooking cavities 1022, the hoods can be arranged symmetrically to ensure consistent hot air circulation between the left and right cavities, or differentiated air duct designs can be adopted according to the needs of different cavities.

[0062] In some embodiments, a second heating element 114 is optionally provided on the fan hood structure 112 and connected in series with the first heating element 104, which further optimizes the hot air circulation system and improves cooking efficiency and heat energy utilization.

[0063] Since the fan blade 110 is installed inside the cooking cavity 1022, the drive motor 108 drives the fan blade 110 to rotate at high speed. The second heating element 114 is located on the hood structure 112. Air is drawn into the hood under the action of the fan blade 110 and heated by the second heating element 114, thereby raising the initial air temperature.

[0064] Because the hood structure 112 can control the airflow path, hot air will enter the cooking cavity 1022 in a predetermined direction. After entering the cooking cavity 1022, the air will be enhanced by the first heating element 104 to reach a higher temperature, achieving the final frying and grilling effect.

[0065] The first heating element 104 is typically located at the top, side wall, or bottom of the cooking cavity 1022, and is connected in series with the second heating element 114 to ensure that hot air circulates continuously throughout the cavity without affecting the cooking effect due to insufficient temperature.

[0066] The air passing through the first heating element 104 is further guided and circulated again by the rotation of the fan blades 110, ensuring even heat distribution throughout the cavity. Because the air circulates repeatedly and is heated by both heating elements, every part of the food is heated evenly, avoiding the problems of localized overheating or temperature dead zones that occur in traditional air fryers 100.

[0067] The second heating element 114 is mainly used to enhance the heating effect of the hot air, ensuring that the hot air reaches the ideal temperature before entering the cooking cavity 1022, thereby improving cooking efficiency and the uniformity of food heating. Since the fan shroud structure 112 is located in the path of the hot air blown out by the fan blade 110, the second heating element 114 can heat the air, ensuring that the temperature of the air entering the cavity is more stable and more uniform.

[0068] The second heating element 114 is mounted on the fan shroud structure 112, typically employing a ring-shaped or mesh-like heating coil layout to ensure that hot air can fully contact the heating element as it passes through the fan shroud, thereby improving heating efficiency. The fan shroud works in conjunction with the fan blades 110, and the fan shroud structure 112 guides the hot air blown out by the fan blades 110 through the second heating element 114, causing the hot air to heat up and resulting in a more uniform and stable temperature after entering the cooking cavity 1022.

[0069] The first heating element 104 and the second heating element 114 are connected in series to form an integrated heating system. This means that the two heating elements share the same current, ensuring more stable power utilization.

[0070] In some embodiments, optionally, the first heating element 104 and the second heating element 114 are respectively arranged on multiple walls of the cooking cavity 1022, forming a more balanced hot air circulation system and optimizing the overall cooking effect. The first heating element 104 can be located at the top and / or bottom of the cooking cavity 1022, serving as the main heating source to initially heat the air, providing the hot air system with basic temperature conditions. The second heating element 114 can be arranged on the fan hood structure 112 and connected in series with the first heating element 104, allowing the hot air to be further heated, reducing temperature attenuation, and improving the quality of the hot air.

[0071] By distributing heating elements across multiple walls, hot air is prevented from concentrating in one direction, ensuring that food is heated evenly from all angles. The hot air forms a more efficient circulation pattern within the cavity, improving cooking uniformity and preventing some parts of the food from being undercooked.

[0072] In some embodiments, the first heating element 104 optionally includes a plurality of heating sections 1042. The first heating element 104 is composed of a plurality of heating sections 1042. These heating sections 1042 are not a single heating element, but are distributed within the cooking cavity 1022 to form a layered heating system. Each heating section 1042 works independently, but together they affect the airflow and heating within the cooking cavity 1022.

[0073] By arranging multiple heating elements 1042 at intervals in the second direction, the heat distribution becomes more uniform, avoiding overheating or cold spots.

[0074] The perpendicularity of the first and second directions helps to enhance the change in airflow path, thereby improving air circulation efficiency and allowing hot air to fully reach every corner of the food.

[0075] Furthermore, the first direction is usually horizontal, and the second direction is usually vertical.

[0076] With multiple heating elements 1042 arranged at intervals, hot air is not concentrated in one area but covers the entire cavity, ensuring that food is heated evenly from all angles. After being heated by the multiple heating elements 1042, the air forms a more efficient circulation path. Because the heating elements 1042 are spaced apart in the second direction, hot air can flow in multiple directions within the cavity and, through a relatively large heat radiation area, allow every part of the cavity to effectively absorb heat.

[0077] In some embodiments, optionally, such as Figure 2 As shown, the oil collection tank 116 is located inside the cooking body 102, allowing oil to be automatically collected during cooking without the need for an external container. Furthermore, the built-in design prevents the oil collection tank 116 from being contaminated or spilled by external factors, maintaining its cleanliness.

[0078] By restricting the oil storage tank 116 to one side of the cooking cavity 1022 in the direction of gravity, the oil will naturally flow to the oil storage tank 116, thus making full use of gravity to guide the oil collection.

[0079] It is important to emphasize that in this design, the multiple cooking cavities 1022 are arranged at intervals along the first direction, and the oil storage tank 116 is located on one side of the cooking cavity 1022 in the direction of gravity. Since the direction of gravity is not parallel to the first direction, this ensures that the oil flows smoothly from the cooking cavity 1022 into the oil storage tank 116. Furthermore, the oil storage tank 116 is located on the side of the cooking cavity 1022 facing the drive cavity 106. If the cooking body 102 is designed as a dual-cavity or multi-cavity unit, the oil storage tanks 116 can be respectively located on one side of the cooking cavity 1022 in the first direction, that is, diagonally below the cooking cavity 1022, facing the drive cavity 106. This maximizes the use of the space between the two spaced-apart cooking cavities 1022, improving space utilization and enabling oil collection in each cooking cavity 1022 while ensuring sufficient space within each cooking cavity 1022.

[0080] In some embodiments, an oil receiving tray 118 is optionally provided and disposed within the cooking body 102, which can cooperate with the oil storage tank 116 to receive and store oil flowing out from different cooking cavities 1022.

[0081] After the grease flows from the cooking cavity 1022 into the oil storage tank 116, it flows into the oil receiving tray 118 through the connecting port, ensuring the continuity and efficiency of grease management.

[0082] Since the oil receiving tray 118 is located on the side of the oil storage tank 116 facing the direction of gravity, grease can flow naturally into the oil receiving tray 118 without the need for additional mechanical pumping or manual intervention. The natural effect of gravity makes the grease flow more smoothly and prevents grease from accumulating in places that are difficult to clean.

[0083] It should be emphasized that since the multiple cooking cavities 1022 are spaced apart, when arranging the oil receiving tray 118, the oil receiving tray 118 can be placed between two adjacent cooking cavities 1022 to further utilize the empty area between the two adjacent cavities and reduce the overall size of the device in the first direction.

[0084] Understandably, the oil collection tray 118 makes cleaning more convenient by centrally collecting grease. Users only need to remove the oil collection tray 118 for cleaning, without worrying about cleaning residual grease in multiple areas. Of course, the oil collection tray 118 is detachably connected to the cooking body 102, thereby improving the convenience of cleaning and allowing for easy disassembly and washing.

[0085] In some embodiments, the drive motor 108 optionally includes a drive shaft 1082 and a motor housing 1084. The motor housing 1084 is connected to the fan shroud structure 112 and is located on the side wall of the fan shroud structure 112 away from the cooking cavity 1022. The drive shaft 1082 passes through two adjacent fan shroud structures 112, enabling the motor to simultaneously drive the rotation of two fan blades 110. The fan blades 110 distribute power to the two fan blades 110 through the extension of the drive shaft, ensuring good airflow and circulation within the two cooking cavities 1022.

[0086] By designing the motor housing 1084 away from the cooking cavity 1022, the motor's vibration will not directly affect the cavity during the cooking process, while also effectively reducing noise. The vibration and noise of the motor during operation are isolated outside the cooking cavity 1022, improving the overall user experience of the device.

[0087] The design of the drive shaft 1082 allows the same motor to drive two fan blades 110, which are responsible for the airflow within the cooking cavity 1022. In this way, the motor can effectively utilize space while improving the air circulation efficiency within both cavities. The synchronized operation of the two fan blades 110 ensures uniform airflow within the cooking cavity 1022, allowing food to receive continuous and even hot air circulation, effectively enhancing the air frying effect, ensuring the food is crispy on the outside and tender on the inside, while shortening cooking time.

[0088] By using a single motor connected to two fan blades 110 via a drive shaft 1082 to achieve dual-chamber airflow, the space-saving design is significantly reduced, as is the number of motors required, thereby lowering production costs. This single-motor, dual-fan-blade 110 design reduces the complexity of the original structure, which required multiple motors and drive units, making the equipment simpler and easier to maintain, further reducing failure rates and maintenance costs.

[0089] By connecting the motor housing 1084 to the fan structure 112, which is away from the high-temperature cooking cavity 1022, the possibility of motor failure is reduced, and the negative impact of temperature on motor life is reduced.

[0090] In some embodiments, a heat dissipation fan 120 may be provided in the drive cavity 106. When the motor starts, the drive shaft 1082 rotates, which drives the heat dissipation fan 120 to rotate, helping to dissipate the heat in the drive cavity 106 and prevent the motor from overheating.

[0091] The cooling fan 120 is designed to be sleeved on the drive shaft 1082 and rotate synchronously with the drive shaft 1082. The cooling fan 120 can generate airflow as the motor rotates, thereby effectively cooling the motor.

[0092] The cooling fan 120, driven by the rotation of the drive shaft 1082, circulates air, thereby quickly dissipating the heat generated by the motor and preventing the motor from malfunctioning due to overheating during prolonged operation. It can be understood that the cooling fan 120 not only cools the motor but also reduces damage to motor components from overheating, improves the long-term stability of the motor, and extends the service life of the equipment.

[0093] In some embodiments, an air inlet 122 may be optionally provided on the wall of the drive cavity 106. When a single motor drives multiple fan blades 110 to rotate, the air inlet 122 may be provided only on the wall of the drive cavity 106, allowing air to enter from one location. With the drive shaft 1082 driving the two fan blades 110 to rotate, multiple air outlets are achieved, while also ensuring that the cooling fan blades 120 dissipate heat from the drive motor 108. In other words, in this solution, the location of the air inlet 122 is relatively simple, but it has stronger functionality. The air drawn into the drive cavity 106 first undergoes heat exchange through the drive motor 108, initially raising its temperature, and then flows into each cooking cavity 1022. Under the action of the first heating element 104 and the second heating element 114, it continues to heat up, reducing the temperature rise and improving cooking efficiency.

[0094] In one specific embodiment, a novel dual-cavity air fryer oven is provided. Currently, dual-cavity air fryers on the market all use a top-mounted fan and vertical air duct, meaning the hot air circulation is from top to bottom. Each cavity requires an independent motor, which is both costly and inefficient, as two separate motors are needed for each cavity. Therefore, this invention addresses the shortcomings of conventional top-mounted air duct air fryers on the market.

[0095] This paper proposes a novel dual-cavity air fryer oven that utilizes a single motor to achieve the dual-cavity frying effect. Specifically, the oven is divided into left and right inner cavities, with the motor located behind the central control panel. The motor's shaft is extended, with fan blades at both ends. The motor is fixed to a sealed convection shroud, inside which a ring-shaped heating element is added. The rapid rotation of the motor circulates the heat from the ring-shaped heating element to both cavities, achieving a hot air circulation effect for air frying the food. This dual-cavity design not only saves on the cost of a motor but also improves production efficiency and enhances product differentiation, making it highly competitive.

[0096] In this design, a single motor is used, located in the middle of the left and right cavities and mounted on the shroud.

[0097] In this design, a single motor is used, and a ring-shaped heating element is placed around the left and right fan blades, the convection shroud, and upper and lower heating elements are located in the left and right inner cavities.

[0098] In this design, one inner cavity on each side is used as the internal sealed space for cooking, and the shape of the inner cavity is not limited.
