Description

Technical Field

[0001] This utility model relates to the field of air fryers, specifically to an air fryer with optimized heat dissipation. Background Technology

[0002] When developing products, manufacturers often customize different appearances for different sales channels. However, different appearances often require multiple sets of molds, leading to a significant increase in manufacturing costs. By using a single product design as a base and changing the top cover, different designs can be derived, greatly reducing mold-making costs.

[0003] The most common way to create a derivative design is to add a decorative ring bracket between the body and top cover of the existing model, and then install metal or plastic decorative pieces on the bracket. After adding the decorative ring bracket, the air fryer becomes taller than the basic design. The original heat dissipation cavity inside the body, which houses the motor, connects with the space inside the decorative ring bracket, forming an enlarged heat dissipation cavity. Because the air inlet on the body is a pre-designed structure, when the heat dissipation cavity becomes larger, the air intake from only a single inlet on the body is insufficient. This leads to inadequate heat dissipation for components such as the motor, easily causing excessive temperature rise in key components, affecting their performance and lifespan. Utility Model Content

[0004] This utility model provides an air fryer with optimized heat dissipation, aiming to solve the technical problem that when a decorative ring support is added to the top of the existing air fryer, the internal heat dissipation cavity space of the air fryer becomes larger, and the air intake is less when relying solely on the air inlet on the body, resulting in poor heat dissipation of components such as motors.

[0005] This utility model discloses an air fryer with optimized heat dissipation, including a body and a top cover. The body has a reflector that divides the interior space into an upper electrical cavity and a lower cooking cavity. The electrical cavity houses a motor and a cooling fan. The air fryer also includes an axially penetrating decorative ring. The top cover is installed at the upper end of the decorative ring, and the body is installed at the lower end of the decorative ring. The body has a first air inlet communicating with the electrical cavity, and a second air inlet communicating with the electrical cavity is provided between the top cover and the decorative ring.

[0006] The air fryer with optimized heat dissipation of this utility model also has the following additional technical features:

[0007] The first air inlet and the second air inlet are offset in the horizontal direction.

[0008] The first air inlet is located at the junction of the decorative ring and the body.

[0009] The rear top edge of the fuselage is recessed to form multiple spaced columns, and the first air inlet is formed between adjacent columns.

[0010] The decorative ring has a through cavity in the middle, and the air fryer includes a touch circuit board, which is disposed in the cavity.

[0011] The first air inlet is located below the touch circuit board to dissipate heat from the lower side of the touch circuit board, and the second air inlet is located above the bottom of the touch circuit board to dissipate heat from the upper side of the touch circuit board.

[0012] The decorative ring includes a decorative ring bracket and a decorative piece. The decorative ring bracket cooperates with the body to form a mounting groove for installing the decorative piece. The outer peripheral wall of the decorative ring bracket is provided with outwardly protruding ribs to form the upper edge of the mounting groove. The top of the body protrudes outward relative to the bottom of the decorative ring bracket to form the lower edge of the mounting groove.

[0013] The bottom of the decorative piece is at least partially provided with an inwardly folded edge, which is inserted into the gap between the decorative ring bracket and the body.

[0014] The decorative piece is formed by a long strip of decorative material, and the two ends of the decorative material are connected by elastic elements.

[0015] The first air inlet is at least partially located on the rear side of the body, and / or the second air inlet is circumferentially located along the edge of the top cover.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. This utility model of an optimized heat dissipation air fryer, with the addition of a decorative ring on the body, creates an enlarged heat dissipation cavity with the original electrical cavity of the body. To ensure the heat dissipation effect of components such as the motor, the air fryer is equipped with a first air inlet and a second air inlet. Compared with the existing single air inlet, it can achieve simultaneous air intake from multiple positions, which helps to increase the air intake volume per unit time, improve the heat dissipation efficiency of components such as the motor, and thus ensure the life of the motor and other components. Furthermore, the first and second air inlets are set at different heights, which can achieve air intake at different heights of the whole machine. This not only avoids the accumulation of air intake, which increases wind resistance and affects air intake efficiency, but also facilitates direct air blowing to dissipate heat from components at or below the air intake height, further improving the heat dissipation effect. Moreover, the two air inlets achieve dual-channel, bidirectional three-dimensional air intake, with a larger air intake volume and a larger exhaust volume, accelerating the removal of moisture and making the food crispier.

[0018] Since the decorative ring is designed for easy assembly and disassembly, and the main body has a first air inlet that can meet the heat dissipation requirements, this application can provide models with or without the decorative ring, depending on market demand. Both models can meet the heat dissipation requirements, which is beneficial for providing different models for different e-commerce platforms, thereby improving the application performance of the product.

[0019] 2. To further improve the heat dissipation effect, the first air inlet and the second air inlet are staggered in the horizontal direction. This allows the airflow from the outer air inlet to flow along a longer radial path after air intake, thus dissipating heat from the devices along the way and cooling more devices. Meanwhile, the airflow from the inner air inlet is closer to the device at the center of the electrical cavity after air intake, which is conducive to the rapid flow of this airflow over the surface of the device, thereby improving its heat dissipation efficiency and avoiding excessive temperature rise due to untimely heat dissipation, which would affect the performance and lifespan of the device.

[0020] 3. To enhance the aesthetics of the chassis while ensuring heat dissipation, the first air inlet is located at the junction of the decorative ring and the chassis. The decorative effect of the decorative ring can be used to weaken the visual impact of the first air inlet, thereby reducing its influence on the overall appearance of the machine.

[0021] Furthermore, the rear top edge of the body is recessed to form multiple spaced columns, with the first air inlet formed between adjacent columns. On one hand, using the recessed space of the body to form the air inlet is easier to process than directly opening holes in the body, and the decorative ring covering the recessed space improves the aesthetics. On the other hand, the multiple columns separate the air inlets to form smaller openings, which, while meeting the air intake requirements, prevents insects and other foreign objects from easily entering the body and damaging the components. It also prevents children from sticking their fingers into the openings, thus increasing safety risks and improving safety and reliability.

[0022] 4. With the decorative ring included, the interior of the ring has a certain space that can accommodate the circuit board, thereby enabling the transformation from a mechanical air fryer to an electronic air fryer. This improves space utilization and expands the range of air fryer models, making it easier to provide different models for different e-commerce platforms and thus enhancing the product's application performance.

[0023] When a touch circuit board is installed in the through-cavity of the decorative ring, in order to improve the heat dissipation of the touch circuit board, the first air inlet and the second air inlet can be set at different heights to dissipate heat on both sides of the touch circuit board, thereby reducing the temperature of the touch circuit board and improving its performance and lifespan.

[0024] 5. The decorative ring includes a decorative ring bracket and a decorative piece. The decorative piece can be designed with different shapes and materials to enhance its aesthetics. To facilitate the installation of the decorative piece, the decorative ring bracket cooperates with the body to form an installation groove for mounting the decorative piece. The outer peripheral wall of the decorative ring bracket has outwardly protruding ribs to form the upper edge of the installation groove. The top of the body protrudes outward relative to the bottom of the decorative ring bracket to form the lower edge of the installation groove. Thus, using the body to form the lower edge of the installation groove simplifies the structure of the decorative ring bracket. The decorative piece is limited by the upper and lower edges of the installation groove, preventing it from shifting and affecting its aesthetics, thus improving installation reliability. Furthermore, due to the shielding effect of the upper and lower edges, it prevents the user's hand from touching the edge of the decorative piece and causing scratches if the edge is sharp, thereby improving safety during use.

[0025] To enhance the stability of the decorative piece installation, at least part of the bottom of the decorative piece has an inwardly folded edge. By inserting the folded edge into the gap between the decorative ring bracket and the body, the decorative piece can be further prevented from shifting up and down, allowing it to be stably attached to the outer wall of the decorative ring bracket, ensuring aesthetics. In addition, the folded edge design prevents hands from contacting the sharp edge of the decorative piece, thus reducing installation risks.

[0026] The decorative piece is installed around the circumference of the decorative ring bracket. To facilitate installation, the decorative piece is formed by a long strip of decorative material. When installing the decorative piece, one end of the decorative material can be positioned first, and then the decorative material can be made to fit around the decorative ring bracket. Finally, when the other end of the decorative material is in place, both ends of the decorative material can be fixed. The two ends of the decorative material can be connected by elastic elements. The deformation of the elastic elements can be used to keep the decorative piece close to the decorative ring bracket, thereby improving the installation effect.

[0027] 6. Generally, the air inlet on the body is located on the rear side of the unit and is not directly visible to the user, which improves the user's visual experience. When a decorative ring is set, a second air inlet is added to ensure the heat dissipation effect of the internal components of the air fryer. Preferably, the second air inlet is set around the edge of the top cover, so that when the air fryer is working, the second air inlet can draw air in circumferentially, which reduces the air resistance and facilitates smooth air intake. It can also increase the air volume and improve the heat dissipation efficiency of the internal components. Attached Figure Description

[0046] like Figures 1 to 8 As shown, this application provides an air fryer with optimized heat dissipation, including a body 10 and a top cover 11. The body 10 is provided with a reflector, which divides the space inside the body 10 into an upper electrical cavity 101 and a lower cooking cavity 102. The electrical cavity 101 is provided with a motor 103 and a cooling fan. The air fryer also includes an axially penetrating decorative ring 12. The top cover 11 is installed at the upper end of the decorative ring 12, and the body 10 is installed at the lower end of the decorative ring 12. The body 10 is provided with a first air inlet 13 communicating with the electrical cavity 101, and a second air inlet 14 communicating with the electrical cavity 101 is provided between the top cover 11 and the decorative ring 12.

[0047] This utility model of an air fryer with optimized heat dissipation, by adding a decorative ring 12 to the body 10, creates an enlarged heat dissipation cavity with the original electrical cavity 101 of the body 10. To ensure the heat dissipation effect of components such as the motor 103, the air fryer is equipped with a first air inlet 13 and a second air inlet 14. Compared with the existing single air inlet, it can achieve simultaneous air intake from multiple positions, which helps to increase the air intake volume per unit time, improve the heat dissipation efficiency of components such as the motor 103, and thus ensure the life of components such as the motor 103. Furthermore, the first air inlet 13 and the second air inlet 14 are set at different heights, which can achieve air intake at different heights of the whole machine. This not only avoids the accumulation of air intake, which increases wind resistance and affects air intake efficiency, but also facilitates direct air blowing to dissipate heat from components at or below the air intake height, further improving the heat dissipation effect. Moreover, the two air inlets achieve dual-channel, bidirectional three-dimensional air intake, with a larger air intake volume and a larger exhaust volume, accelerating the removal of moisture and making the food crispier.

[0048] like Figure 2As shown, the top cover 11, decorative ring 12, and body 10 are distributed from top to bottom. The top cover 11 and body 10 are the original structures. To improve the adaptability of the decorative ring 12, the decorative ring 12 can be manufactured according to the size and assembly structure of the top cover 11 and body 10. The decorative ring 12 and the top cover 11, and the decorative ring 12 and the body 10 can be connected by a snap-fit ​​structure, which is simple and facilitates the disassembly and assembly of the decorative ring 12. It can be understood that with the decorative ring 12, the air fryer can simultaneously draw in air through the first air inlet 13 and the second air inlet 14 when it is working, increasing the air intake volume and meeting the heat dissipation requirements of components such as the motor 103. Without the decorative ring 12, since the body 10 itself has the first air inlet 13, the air intake volume of the first air inlet 13 can meet the heat dissipation requirements of components such as the motor 103 within the original size of the electrical cavity 101. The decorative ring 12, as a structure that is easy to disassemble and assemble, provides manufacturers with the conditions for modification. They can provide models with or without the decorative ring 12 according to market demand. Both models can meet the heat dissipation requirements, which is conducive to providing different models for different e-commerce platforms, thereby improving the application performance of the product.

[0049] In a preferred embodiment, the decorative ring 12 and the top cover 11, and the decorative ring 12 and the body 10 are connected by a snap-fit ​​structure, such as... Figure 2 , Figure 6 and Figure 7 As shown, the top of the decorative ring 12 has a mounting surface 121, and the mounting surface 121 has a first slot 122. Correspondingly, the top cover 11 has a first buckle 111 that mates with the first slot 122. Furthermore, the inner sidewall of the decorative ring 12 has a downwardly extending second buckle 123. Correspondingly, the body 10 has a second slot 104 that mates with the second buckle 123. The buckle connection method is simple in structure and easy to install, making it easy to assemble different models of air fryers and improving assembly efficiency. Preferably, the first slot 122 and the second buckle 123 are staggered, which makes reasonable use of space while ensuring the overall structural strength of the decorative ring 12 and improving durability.

[0050] like Figure 1 As shown, the first air inlet 13 and the second air inlet 14 are staggered in the vertical direction, so that even when the whole machine is taller, both the body 10 and the decorative ring 12 can receive air, which can meet the heat dissipation requirements after the internal space of the machine is increased.

[0051] To further improve heat dissipation, as a preferred embodiment, the first air inlet 13 and the second air inlet 14 are staggered in the horizontal direction.

[0052] For example, the first air inlet 13 is located radially outside the second air inlet 14. This design allows the airflow from the outer air inlet to travel a longer radial path after air intake, thus dissipating heat from the devices along the way and cooling more devices. Meanwhile, the airflow from the inner air inlet is closer to the device at the center of the electrical cavity 101 after air intake, which is beneficial for this part of the airflow to quickly flow over the surface of the device, thereby improving its heat dissipation efficiency and avoiding excessive temperature rise due to untimely heat dissipation, which would affect the performance and lifespan of the device.

[0053] like Figure 1 He Ru Figure 4 As shown, assuming the motor 103 is located at the center of the electrical cavity 101, the radial distance between the first air inlet 13 and the motor 103 is shorter than that between the second air inlet 14 and the first air inlet 13. Therefore, when air enters through the first air inlet 13, the airflow can reach the surface of the motor 103 more quickly, which is beneficial to improving the heat dissipation efficiency of the motor 103.

[0054] As a preferred implementation method, such as Figure 1 As shown, the first air inlet 13 is located at the junction of the decorative ring 12 and the body 10. This allows the decorative effect of the decorative ring 12 to weaken the visual impact of the first air inlet 13, thereby reducing the impact of the first air inlet 13 on the overall appearance of the machine and improving the aesthetics of the body 10.

[0055] In one embodiment, the rear top edge of the fuselage 10 is recessed to form a plurality of spaced columns 15, and a first air inlet 13 is formed between adjacent columns 15.

[0056] like Figure 2 As shown, on the one hand, using the recessed space of the body 10 to form the air inlet is easier to process than directly opening a hole in the body 10, and the decorative ring 12 covering the top of the recessed space can improve the aesthetics; on the other hand, the air inlet with a smaller opening formed by multiple pillars 15 can prevent the opening from being too large, which would allow insects and other foreign objects to easily enter the body 10 and damage the components, while ensuring sufficient air intake. It can also prevent children from sticking their fingers into the opening and increasing the safety risk, thereby improving the safety and reliability of use.

[0057] like Figure 3 As shown, the top of the column 15 is provided with a horizontal step surface 151 and a vertical limiting surface 152 located inside the step surface 151. The bottom end of the decorative ring 12 abuts against the step surface 151 so that the top of the body 10 and the column 15 jointly support the decorative ring 12. On this basis, the limiting surface 152 can prevent the decorative ring 12 from moving inward, thereby improving the installation stability of the decorative ring 12.

[0058] Preferably, the first air inlet 13 is located only on the rear side of the body 10 and is not directly visible to the user, thus improving the user's visual experience. In other embodiments, the first air inlet 13 may also be located in other positions around the body 10, or the first air inlet 13 may be arranged circumferentially around the body 10, which can increase the air intake and improve the heat dissipation efficiency of the device.

[0059] As a preferred embodiment, the second air inlet 14 is arranged circumferentially along the edge of the top cover 11, so that when the air fryer is working, the second air inlet 14 can introduce air in the circumferential direction, which reduces the air resistance and facilitates smooth air intake. It can also increase the air volume and improve the heat dissipation efficiency of the internal components.

[0060] like Figure 1 and Figure 2 As shown, the top of the decorative ring 12 is provided with a recessed mounting surface 121, and the edge of the mounting surface 121 is provided with annularly distributed ribs 124. The top cover 11 is installed on the inner side of the ribs 124. For example, the top cover 11 is snapped to the decorative ring 12. The fit gap between the edge of the top cover 11 and the mounting surface 121 forms the second air inlet 14. In this way, it is not necessary to set a separate air inlet. Instead, the second air inlet 14 is formed by the assembly of structural components, which helps to simplify the structural configuration and reduce costs.

[0061] With the decorative ring 12 in place, there is a certain space inside the decorative ring 12, which can be used to accommodate the circuit board, thereby realizing the transformation from a mechanical air fryer to an electronic air fryer. This improves space utilization and expands the range of air fryer models, which is beneficial for providing different models to different e-commerce platforms, thereby enhancing the application performance of the product.

[0062] As a preferred implementation method, such as Figure 2 , Figure 6 and Figure 7 As shown, the decorative ring 12 has a through cavity 125 in the middle, and the air fryer includes a touch circuit board 16, which is disposed in the cavity 125.

[0063] Given a fixed size for the body 10, there would be insufficient space to place the touch circuit board 16 directly on the body 10. Adding a decorative ring 12 allows for the use of its internal space, which accommodates the touch circuit board 16. This satisfies both decorative purposes and allows for a more efficient arrangement of the touch circuit board 16, paving the way for the transition from a mechanical air fryer to an electronic model. Furthermore, to enable the use of an electronic air fryer, an operation area associated with the touch circuit board 16 can be added to the machine. This area includes function keys for user operation. Common user methods include touch control and button pressing, which are easier and less strenuous than mechanical knobs, improving the user experience and resulting in a cleaner, more aesthetically pleasing appearance. The operation area can be located on the decorative ring 12 or the top cover 11, depending on the specific needs.

[0064] In addition to accommodating the components, the aforementioned cavity 125 also forms a large ventilation opening, which facilitates the rapid downward flow of air from the second air inlet 14 into the body 10 to dissipate heat from the components, making the airflow circulation smoother.

[0065] In one embodiment, the first air inlet 13 is located below the touch circuit board 16 for heat dissipation of the lower side of the touch circuit board 16, and the second air inlet 14 is located above the bottom of the touch circuit board 16 for heat dissipation of the upper side of the touch circuit board 16.

[0066] like Figure 2 As shown, by using the first air inlet 13 and the second air inlet 14 at different heights to dissipate heat from both sides of the touch circuit board 16, the temperature of the touch circuit board 16 can be effectively reduced, improving its performance and lifespan. Preferably, the second air inlet 14 is positioned directly opposite the side of the touch circuit board 16, so that the airflow flowing in from the second air inlet 14 can directly blow onto the touch circuit board 16, achieving efficient heat dissipation.

[0067] In a preferred embodiment, the decorative ring 12 includes a decorative ring bracket 17 and a decorative piece 18. The decorative ring bracket 17 cooperates with the body 10 to form a mounting groove 171 for mounting the decorative piece 18. The outer peripheral wall of the decorative ring bracket 17 is provided with outwardly protruding ribs to form the upper edge 172 of the mounting groove 171. The top of the body 10 protrudes outward relative to the bottom of the decorative ring bracket 17 to form the lower edge 105 of the mounting groove 171.

[0068] like Figure 4 and Figure 5As shown, the structure of the decorative ring bracket 17 can be simplified by using the lower edge 105 of the mounting groove 171 formed by the body 10. The decorative piece 18 is limited by the upper edge 172 and the lower edge 105 of the mounting groove 171, which can prevent the decorative piece 18 from shifting up and down and affecting the aesthetics, and improve the installation reliability. Moreover, due to the blocking effect of the upper edge 172 and the lower edge 105, it can prevent the user's hand from touching the edge of the decorative piece 18 and causing scratches if the edge is sharp, thus improving the safety of use.

[0069] Specifically, the decorative ring bracket 17 can be made of plastic, while the decorative piece 18 can be made of materials such as plastic or metal, and can be set according to needs. For example, the metal decorative piece 18 has a better luster and is more aesthetically pleasing.

[0070] In one embodiment, the bottom of the decorative piece 18 is at least partially provided with an inwardly folded edge 181, which is inserted into the gap between the decorative ring bracket 17 and the body 10.

[0071] like Figure 5 As shown, by inserting the folded edge 181 into the gap between the decorative ring bracket 17 and the body 10, the decorative piece 18 can be further prevented from shifting up and down, and the decorative piece 18 can be stably attached to the outer wall of the decorative ring bracket 17, ensuring aesthetics. In addition, the design of the folded edge 181 can prevent the sharp edge of the decorative piece 18 from coming into contact with the hand, thus reducing the installation risk.

[0072] like Figure 8 As shown, the decorative piece 18 located at the bottom of the decorative ring bracket 17 has a folded edge 181. With an air outlet at the rear of the unit 10, by strengthening the limiting position of the decorative piece 18 at the rear of the decorative ring bracket 17, the impact of the airflow on the decorative piece 18, preventing it from shifting upwards, can be reduced, thus ensuring the installation stability of the decorative piece 18. It is understood that the folded edge 181 can be a non-connected structure, such as multiple folded edges 181 spaced apart, or it can be a continuous structure covering the entire length of the decorative piece 18, depending on the requirements. This application does not impose any limitations on this design.

[0073] In one embodiment, the decorative piece 18 is formed by an elongated decorative element, the two ends of which are connected by an elastic element 19.

[0074] like Figure 7 and Figure 8As shown, the decorative piece 18 is installed circumferentially around the decorative ring bracket 17. To facilitate the installation of the decorative piece 18, it is formed by a long strip of decorative material. During installation, one end of the decorative material can be positioned first, then the material can be wrapped around the decorative ring bracket 17 to fit snugly. Finally, once the other end is in place, both ends of the material can be fixed. The two ends of the decorative material can be connected by an elastic element 19. The deformation of the elastic element 19 ensures that the decorative piece 18 remains tightly fitted to the decorative ring bracket 17, thus improving the installation effect. Furthermore, the use of the elastic element 19 can compensate for assembly tolerances; even slight deviations in the length of the decorative piece 18 will not affect its normal installation. The elastic element 19 can be, for example, a spring.
