Description

Technical Field

[0001] This utility model belongs to the technical field of food heating equipment, specifically relating to an air outlet device for an air fryer. Background Technology

[0002] An air fryer is a cooking appliance that typically includes a cooking chamber and a heating element. A fan directs the airflow, generating heat from the heating element, onto the food inside the cooking chamber to heat it. During the heating process, some moisture is released, so air fryers usually have vents to expel some of this moisture.

[0003] In the existing technology, the air fryer's air outlet device only has one air outlet. During the operation of the fan, part of the airflow is discharged through the air outlet. This air outlet device has an unreasonable structure and low air outlet efficiency. Utility Model Content

[0004] This invention provides an air outlet device for an air fryer, aiming to solve the problem of low air outlet efficiency in existing air fryer air outlet devices.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An air outlet device for an air fryer includes a housing, on which a fan and a heating element are disposed, with the fan located above the heating element;

[0007] The housing has a cavity, and the fan and the heating assembly are both installed in the cavity. The cavity is also equipped with an air guide plate.

[0008] The air guide plate includes a wind-receiving side that guides the airflow generated by the fan. The cover is also provided with an air outlet. The air guide plate guides a portion of the airflow generated by the fan into the air outlet. The air outlet communicates with the cavity and is located on the cover near the wind-receiving side.

[0009] A further improved solution: the upper end of the air guide plate is fixedly connected to the inner wall of the cover, and the lower end of the air guide plate is fixedly connected to the heating component.

[0010] Based on the above technical solution: the upper end of the air guide plate is fixedly connected to the inner wall of the casing. This connection method ensures the stability of the air guide plate inside the air fryer, preventing displacement due to vibration or external forces. The lower end of the air guide plate is fixedly connected to the heating element. This design enhances the stability of the heating element through physical connection, preventing it from loosening during use.

[0011] A further improved solution: An assembly plate is provided at the upper end of the air guide plate, and the air guide plate is fixed to the inner wall of the cover through the assembly plate, with the assembly plate perpendicular to the air guide plate.

[0012] Based on the above technical solution, the perpendicular design of the assembly plate and the air guide plate increases the structural stability of the air guide plate inside the air fryer. As an additional support plate, the assembly plate effectively prevents the air guide plate from deforming or shifting due to wind force during use. This design helps improve the overall durability and lifespan of the air fryer. The assembly plate also makes the installation and removal of the air guide plate more convenient. During the manufacturing and maintenance of the air fryer, workers can easily fix the air guide plate in a designated position using the assembly plate, or remove it from inside the air fryer for cleaning or replacement. This design not only improves production efficiency but also reduces maintenance costs.

[0013] A further improved solution: the assembly plate protrudes from the air guide plate in a direction away from the wind-receiving side, and the assembly plate and the air guide plate are an integral structure.

[0014] Based on the above technical solution: the assembly plate protrudes from the air guide plate away from the windward side, which can more effectively guide airflow and reduce turbulence and vortices on the windward side of the air guide plate. This helps improve the airflow efficiency inside the air fryer, allowing hot air to be distributed more evenly to the food surface, improving cooking results and the evenness of food heating. The assembly plate and air guide plate are an integrated structure, simplifying the production process. It reduces assembly and connection steps, lowering production costs and time. The integrated structure allows the assembly plate and air guide plate to be manufactured and processed simultaneously, eliminating the need for additional assembly and debugging work. This helps improve production efficiency and shorten product delivery cycles. The integrated structure of the assembly plate and air guide plate reduces dead corners and hard-to-reach areas during cleaning. Users can more easily clean dirt and residue from the surfaces of the air guide plate and assembly plate, keeping the air fryer hygienic and clean. The easy-to-clean and maintain design helps reduce dirt and corrosion on the surfaces of the air guide plate and assembly plate, thereby extending their service life.

[0015] A further improvement: The lower end of the air guide plate is provided with a connecting part that cooperates with the heating component.

[0016] Based on the above technical solution: the connecting part provides a stable support point for the heating component. Through a tight fit with the lower end of the air guide plate, the heating component can be firmly fixed inside the air fryer, and is not easily loosened or displaced by vibration or external forces. The design of the connecting part makes the installation and removal of the heating component more convenient. During the manufacturing and maintenance of the air fryer, workers can easily fix the heating component to the air guide plate through the connecting part, or remove it from the air guide plate for cleaning or replacement. This design not only improves production efficiency but also reduces maintenance costs.

[0017] A further improved solution: The heating component is a heating tube, which is coiled inside the cavity, and the connecting part is a groove, in which a portion of the heating tube is fixed.

[0018] Based on the above technical solution: the heating element is connected to the air guide plate through a groove. This design ensures that the heating element is more stable inside the air fryer and is less prone to loosening or displacement due to vibration or external forces. The stable heating element design reduces safety hazards caused by loosening or displacement, such as short circuits or electrical leakage, thus ensuring the safe use of the air fryer.

[0019] A further improved solution: The cavity is also provided with a fixing frame for fixing the heating component. The upper end of the fixing frame is fixed to the inner wall of the cover, and the lower end of the fixing frame is provided with a slot for engaging the heating tube.

[0020] Based on the above technical solution: the heating element is initially fixed not only by the groove at the lower end of the air guide plate, but also by the slots on the mounting bracket. This dual fixing method ensures that the heating element is more stable inside the air fryer and is less prone to loosening or displacement due to vibration or external forces. The mounting bracket design makes the installation of the heating element simpler and more intuitive. Operators only need to place the heating element into the slot of the mounting bracket to complete the initial fixing, and then further fix it by the groove at the lower end of the air guide plate. Similarly, the mounting bracket design also makes the disassembly of the heating element more convenient. When cleaning, maintenance, or replacement of the heating element is required, operators can easily disassemble the heating element to perform the necessary operations.

[0021] A further improved solution: The fixing frame is provided with an upper clamping arm and a lower clamping arm, and the clamping groove is formed between the upper clamping arm and the lower clamping arm. A part of the heating tube is located between the upper clamping arm and the lower clamping arm.

[0022] Based on the above technical solution, the design of the upper and lower clamping arms makes the installation of the heating element simpler and more intuitive. Users or maintenance personnel only need to place the heating element into the clamping slot, and the installation is completed by the locking mechanism, without the need for additional tools or complicated procedures. The design of the upper and lower clamping arms also makes the disassembly of the heating element more convenient. When cleaning, maintenance, or replacement of the heating element is required, users or maintenance personnel can easily remove the heating element by releasing the clamps to perform the necessary operations.

[0023] A further improved solution: The upper end of the fixing frame is provided with a fixing plate, and the fixing plate is provided with assembly holes.

[0024] Based on the above technical solution: the design of the fixing plate provides an additional support surface for the mounting bracket, making the connection between the mounting bracket and other components of the air fryer more stable. The mounting holes are used to securely connect the fixing plate to the inner wall of the casing or other related components, thus forming a stable overall structure. Due to the presence of the fixing plate, vibrations generated during air fryer operation are better suppressed. This helps reduce noise while protecting the internal components of the air fryer from vibration damage. The mounting hole design makes the installation of the mounting bracket simpler and more intuitive. Workers can connect the fixing plate to the inner wall of the casing or other related components using bolts, screws, or other fasteners to complete the installation of the mounting bracket. This design improves installation efficiency and reduces installation difficulty.

[0025] A further improved solution: the fan is a centrifugal fan that rotates clockwise; or the fan rotates counterclockwise.

[0026] Based on the above technical solution: the clockwise or counterclockwise rotation of the fan can not only ensure that the food is subjected to uniform hot air, improve the cooking effect and the even heating of the food, but also reduce noise and vibration, and improve the overall quality of the air fryer.

[0027] The beneficial effects of this utility model are as follows:

[0028] This invention utilizes a guide vane design to direct the airflow generated by the fan towards the outlet, avoiding airflow turbulence and energy loss. This directional airflow method allows a portion of the gas to be effectively output through the outlet during fan operation. By incorporating the guide vane, turbulence and eddies in the airflow are reduced, thereby lowering noise levels and providing users with a quieter environment when using the air fryer. Simultaneously, a portion of the airflow rotating within the cavity, driven by the fan, is guided by the guide vane and directly discharged through the outlet, effectively improving the airflow efficiency of the device.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by users of the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0038] refer to Figures 1 to 5 An air outlet device for an air fryer includes a housing 1, on which a fan 2 and a heating assembly 3 are disposed, with the fan 2 located above the heating assembly 3;

[0039] The housing 1 is provided with a cavity 4, the fan 2 and the heating component 3 are both installed in the cavity 4, and the cavity 4 is provided with an air guide plate 5;

[0040] The air guide plate 5 includes a wind-receiving side that guides the airflow generated by the fan 2. The cover 1 is also provided with an air outlet 6. The air guide plate 5 guides a portion of the airflow generated by the fan 2 into the air outlet 6. The air outlet 6 communicates with the cavity 4. Furthermore, the air outlet 6 is located on the cover 1 near the wind-receiving side.

[0041] The fan 2 is positioned above the heating element 3. During operation, the fan 2 generates airflow. Part of this airflow is heated by the heating element 3 and then blown into the cooking cavity to heat the food inside. The other part of the airflow generated by the fan 2 rotates within the cavity 4, and a portion of this rotating airflow is discharged through the air outlet 6. The gap between the cooking cavity and the cover 1 allows outside air to enter the cooking cavity, achieving gas circulation within the cooking cavity.

[0042] The air receiving surface refers to the surface directly facing the airflow inside the cavity 4 as it rotates under the drive of the fan 2. After the airflow reaches the air receiving surface, a portion of it is guided by the air guide plate 5 and discharged through the air outlet 6.

[0043] refer to Figure 4 Specifically: the upper end of the air guide plate 5 is fixedly connected to the inner wall of the housing 1, and the lower end of the air guide plate 5 is fixedly connected to the heating assembly 3. An assembly plate 7 is provided at the upper end of the air guide plate 5, and the air guide plate 5 is fixed to the inner wall of the housing 1 via the assembly plate 7, which is perpendicular to the air guide plate 5. The assembly plate 7 can be fixed to the inner wall of the housing 1 with screws, or the air guide plate 5 can be welded to the inner wall of the housing 1.

[0044] Wherein: the assembly plate 7 protrudes from the air guide plate 5 in a direction away from the windward side, and the assembly plate 7 and the air guide plate 5 are an integral structure. Because the assembly plate 7 protrudes from the air guide plate 5 in a direction away from the windward side, it can prevent the airflow in the cavity 4 from forming turbulence on the windward side, thus optimizing the airflow guiding function of the air guide plate 5. The assembly plate 7 can be directly welded to the inner wall of the cover 1. Holes can also be provided on the assembly plate 7; screw holes are provided on the inner wall of the cover 1, and screws can be installed on the assembly plate 7, allowing the assembly plate 7 to be fixed to the inner wall of the cover 1 by screws.

[0045] Specifically, the lower end of the air guide plate 5 is provided with a connecting part 8 that cooperates with the heating component 3. The heating component 3 is a heating tube, which is coiled inside the cavity 4. The connecting part 8 is a groove, and a portion of the heating tube is fixed in the groove. The cross-sectional shape of the groove can be semi-circular, and the cross-sectional shape of the heating tube can be circular. That is, the cross-sectional shape of the groove matches the cross-sectional shape of the heating tube. The heating tube can be welded into the groove.

[0046] refer to Figure 5 Specifically: The cavity 4 is further provided with a fixing frame 9 for fixing the heating assembly 3. The upper end of the fixing frame 9 is fixed to the inner wall of the housing 1, and the lower end of the fixing frame 9 is provided with a slot for engaging the heating tube. The fixing frame 9 is provided with an upper locking arm 10 and a lower locking arm 11, forming the slot between the upper locking arm 10 and the lower locking arm 11. A portion of the heating tube is located between the upper locking arm 10 and the lower locking arm 11. Both the upper locking arm 10 and the lower locking arm 11 are integrally formed with the fixing frame 9. The upper end of the fixing frame 9 is provided with a fixing plate 12, which has mounting holes. The fixing plate 12 is used to fix the fixing frame 9 to the inner wall of the housing 1. For example, the fixing plate 12 can be fixed to the inner wall of the housing 1 with screws. The screws pass through the mounting holes and engage with the screw holes on the housing 1.

[0047] Wherein: the fan 2 is a centrifugal fan 2, which rotates clockwise or counterclockwise. Whether the fan 2 rotates clockwise or counterclockwise, it drives the airflow within the cavity 4 to rotate during rotation. The airflow within the cavity 4 blows directly onto the air-receiving surface of the guide plate 5 during rotation. That is, the air-receiving surface of the guide plate 5 is the surface directly hit by the airflow driven by the fan 2 within the cavity 4. After the airflow driven by the fan 2 is blown onto the air-receiving surface, a portion is discharged through the air outlet, while the other portion continues to rotate within the cavity 4, or, after being guided by the fan 2, is blown onto the food inside the cooking cavity.

[0048] The working principle of this embodiment:

[0049] When the user starts the air fryer, the heating element 3 begins to work, heating the air inside the cavity 4. Simultaneously, the fan 2 also starts operating, generating airflow. As the fan 2 continues to operate, a large amount of airflow is drawn into the housing 1 and heated by the heating element 3 to form hot air. The design of the air guide plate 5 effectively guides the hot air during its flow. Specifically, the air guide plate 5 has a receiving side that receives the airflow from the fan 2 and directs it in a specific direction; that is, under the action of the air guide plate 5, a portion of the hot air is directed into the air outlet 6. This air outlet 6 communicates with the cavity 4 and is located on the housing 1 near the receiving side of the air guide plate 5, thus effectively expelling a portion of the airflow from the cavity 4.

[0050] The hot air generated by heating element 3 circulates continuously under the drive of fan 2. Air guide plate 5 continues to guide the air, ensuring that the hot air evenly covers the food surface, while some of the moisture released from the food is expelled through air outlet 6. As cooking time progresses, the food surface gradually becomes golden brown and crispy, achieving a similar effect to deep-frying. Simultaneously, due to the circulation of hot air, the interior of the food is also fully heated and cooked.

[0051] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
