TECHNICAL FIELD
[0001] The utility model relates to the field of air fryer, specifically relates to a structure optimization's air fryer. BACKGROUND
[0002] The common mechanical style air fryer operates the machine through the knob structure, and the user is inconvenient to operate and has poor experience, in view of this problem, the electronic style air fryer has appeared on the market, and the user can control the machine work through the function operation key on the machine top cover, which is quick and convenient, and can improve the user's use experience.
[0003] The existing mechanical and electronic air fryers need to be separately and individually opened machine body molds due to different internal parts, and the cost is higher. The applicant thinks that if the machine body of the mechanical air fryer is improved, the air fryer can be changed without changing the original machine body structure, so that the existing machine body can be used to improve the universality of the structural parts, so that the model change can be realized under the premise of saving cost, thereby meeting the market demand. However, the mechanical model is generally expanded into an electronic model by adding a circuit board, and due to the compact design of the original machine body, there is generally no space to additionally install the circuit board, so it is difficult to realize the model change from mechanical to electronic. UTILITARIAN CONTENT
[0004] The utility model provides a structure optimization's air fryer, aims at solving the technical problem of poor machine body universality, unable to realize the model change from mechanical to electronic, and high development cost.
[0005] The utility model discloses a structure optimization's air fryer, including machine body and top cap, be equipped with the reflector cover in the machine body, the reflector cover divides the space in the machine body into the electric appliance cavity of upper side and the cooking cavity of lower side, be provided with motor and cooling fan in the electric appliance cavity, be provided with the extension support between top cap and machine body, the extension support is equipped with the longitudinal through empty cavity, the air fryer includes circuit board, the circuit board sets up in empty cavity, top cap is equipped with the operation area corresponding circuit board.
[0006] The utility model discloses a structure optimization's air fryer, still has following additional technical features:
[0007] The air fryer is provided with a first air inlet and a second air inlet communicated with the electric appliance cavity, the first air inlet is arranged on the machine body, and the second air inlet is arranged between the extension support and the top cap.
[0008] The first air inlet and the second air inlet are arranged in a staggered manner in the horizontal direction.
[0009] The first air inlet is lower than the circuit board, and the second air inlet is higher than the circuit board.
[0010] The extension support and the body cooperate to form a mounting groove, the outer peripheral wall of the extension support protrudes to form an upper edge of the mounting groove, and the top of the body protrudes relative to the bottom of the extension support to form a lower edge of the mounting groove, and an annular decorative ring is mounted in the mounting groove.
[0011] The bottom of the decorative ring is provided with an inwardly folded edge, and the edge is inserted into a gap between the extension support and the body.
[0012] The decorative ring is formed by a long strip-shaped decorative piece, and the two ends of the decorative piece are connected by elastic pieces.
[0013] The body is provided with a first air inlet in communication with the electric appliance cavity, and the first air inlet is arranged between the extension support and the body.
[0014] The top of the body is provided with a top plate, and the top plate abuts against the lower end of the circuit board.
[0015] The circuit board is fixedly connected with the extension support to form a module.
[0016] Due to the above technical scheme, the air fryer has the following beneficial effects:
[0017] 1. The air fryer with an optimized structure can realize the upgrading of the air fryer by using the body of the existing product, and by adding relatively small components, the processing technology can be greatly simplified and the cost can be saved; specifically, by adding an extension support, the internal space of the extension support is used to accommodate a circuit board to realize the upgrading of the air fryer, and an operation area is arranged on the top cover, so that the user can operate the machine in the operation area, which is convenient and fast, and since the operation area is arranged at the top of the machine at a high position, the user can prevent bending over to operate, and the user experience is improved.
[0018] It can be understood that the operation area is generally provided with function operation keys for user operation. There are various types of common function operation keys. When different function operation keys are set, different models of circuit boards can be matched accordingly, and appropriate size of the expansion support is set according to the size of the circuit board to improve the flexibility of structure processing and adaptation. For example, when the operation area is provided with spaced touch keys, the required circuit board is relatively thin. In this case, the expansion support with small longitudinal height can be matched. When the operation area is provided with press keys, the required circuit board is relatively thick or needs to avoid the cavity with a larger longitudinal space to accommodate related accessories (such as the type configured with a spring). In this case, the expansion support with large longitudinal height can be matched. By configuring different specifications of the expansion support, different circuit boards and operation structures can be matched to further enrich the models of the air fryer, which is beneficial to provide different models for different e-commerce platforms, thereby improving the application performance of the product.
[0019] 2. In the case of adding an expansion support to the machine body, the internal space of the expansion support and the original electric cavity of the machine body form an enlarged heat dissipation cavity. In order to ensure the heat dissipation effect of the motor and other devices, the air fryer is provided with a first air inlet and a second air inlet. Compared with the existing single air inlet, multiple positions can be inhaled at the same time, which is beneficial to increase the air intake amount per unit time and improve the heat dissipation efficiency of the motor and other devices, thereby ensuring the service life of the motor and other devices. Further, the first air inlet and the second air inlet are arranged at different heights, which can realize air intake at different heights of the whole machine. It can not only avoid the increase of air resistance caused by the aggregation of air intake to affect the air intake efficiency, but also is beneficial to directly blow and heat the devices below the air intake height, thereby further improving the heat dissipation effect.
[0020] In order to further improve the heat dissipation effect, the first air inlet and the second air inlet are arranged in a staggered manner in the horizontal direction. After the air inlet on the outer side is inhaled, the airflow can flow along a longer path to dissipate heat to the devices along the way, so as to cool more devices. The air inlet on the inner side is close to the devices in the center of the electric cavity after air intake, which is beneficial to the rapid flow of this part of airflow through the surface of the devices to improve the heat dissipation efficiency, thereby avoiding the high temperature rise caused by the delay of heat dissipation to affect the performance and service life of the devices.
[0021] In order to improve the heat dissipation effect of the circuit board, the first air inlet is lower than the circuit board, and the second air inlet is higher than the circuit board. The first air inlet and the second air inlet arranged at different heights can be used to dissipate heat on both sides of the circuit board, thereby reducing the temperature of the circuit board and improving its use performance and service life.
[0022] 3. In order to improve the appearance, the outer periphery of the expansion support is provided with a decorative ring, which can be designed in different shapes and materials to improve the appearance. Further, in order to realize the installation of the decorative ring, the expansion support and the body cooperate to form a mounting groove, the outer wall of the expansion support is protruded to form the upper edge of the mounting groove, and the top of the body is protruded outward compared to the bottom of the expansion support to form the lower edge of the mounting groove. The decorative ring is installed in the mounting groove. Thus, the lower edge of the mounting groove is formed by the body, which can simplify the structure of the expansion support. The decorative ring is limited by the upper edge and the lower edge of the mounting groove, which can prevent the decorative ring from moving up and down and affecting the appearance, improve the installation reliability, and prevent the user's hand from touching the edge of the decorative ring in the case of sharp edge, thereby improving the safety in use.
[0023] In order to strengthen the stability of the decorative ring installation, the bottom of the decorative ring is at least partially provided with a folded edge which is folded inward. By inserting the folded edge into the gap between the expansion support and the body, the decorative ring can be further prevented from moving up and down, and the decorative ring can be stably attached to the outer wall of the expansion support, thereby ensuring the appearance. In addition, the design of the folded edge can prevent the hand from contacting the sharp edge of the decorative ring, thereby reducing the risk of installation.
[0024] The decorative ring is installed along the circumference of the expansion support. In order to facilitate the installation of the decorative ring, the decorative ring is formed by a long strip-shaped decorative piece, that is, one end of the decorative piece is positioned first, then the decorative piece is attached around the expansion support, and finally the two ends of the decorative piece are fixed when the other end of the decorative piece is in place. The two ends of the decorative piece can be connected by an elastic piece, which can always attach the decorative ring to the expansion support by the deformation of the elastic piece, thereby improving the installation effect.
[0025] 4. Under the premise of meeting the heat dissipation of the body, in order to improve the appearance of the body, a first air inlet is provided on the body and communicates with the electric appliance cavity. The first air inlet is arranged between the expansion support and the body, and the decorative effect of the expansion support can be used to weaken the visual sense of the first air inlet, thereby reducing the influence of the first air inlet on the appearance of the whole machine.
[0026] 5. In order to prevent the user from pressing the operation area when operating, which affects the use experience, the top of the body is provided with a top plate, which abuts against the lower end of the circuit board. The top plate provides certain support for the circuit board. When the user presses the keys of the operation area, the force is transmitted downward, thereby realizing effective pressing of the keys, preventing invalid operation caused by false pressing, and affecting the hand feeling.
[0027] 6. It can be understood that the modular design has many advantages, such as the modular structure can prevent parts from being missing during factory transportation, and can omit the assembly step during use. Based on this, the circuit board and the extension support are fixedly connected to form a module. By forming a modular structure, the circuit board and the extension support can omit the installation process between the circuit board and the extension support when assembled with other structures of the air fryer, and the assembly efficiency of the whole machine can be effectively improved.

[0045] As shown in Figures 1 to 7 The present application provides a structure optimized air fryer, including body 10 and top cover 11, the body 10 is equipped with the reflecting cover, the reflecting cover divides the space in the body 10 into the upper electrical cavity 101 and the lower cooking cavity 102, the electrical cavity 101 is provided with motor 103 and cooling fan, the top cover 11 and the body 10 are provided with expansion bracket 12, expansion bracket 12 is equipped with longitudinal through empty cavity 124, air fryer includes circuit board 15, circuit board 15 is arranged in empty cavity 124, the top cover 11 is equipped with the operating area corresponding to circuit board 15.
[0046] The structure optimized air fryer of the present application can realize the modification of air fryer on the basis of retaining the original body 10 structure, by adding relatively small size components, the processing technology can be greatly simplified, and the cost can be saved, specifically, by adding expansion bracket 12, the internal space is used to accommodate circuit board 15 to realize the modification of air fryer, and the operating area is arranged on the top cover 11, when using the machine, the user operates in the operating area, which is convenient and fast, and because the operating area is arranged at the top of the machine at a high position, the user can prevent bending to operate, and the use experience of the user is improved.
[0047] It can be understood that the operation area is generally provided with function operation keys for user operation. There are various types of common function operation keys. When different function operation keys are set, different models of circuit boards 15 can be matched accordingly, and the appropriate size of the expansion bracket 12 is set according to the size of the circuit board 15, so as to improve the flexibility of structural part processing and adaptation. For example, when the operation area is provided with spaced touch keys, the required circuit board 15 is relatively thin, and in this case, the expansion bracket 12 with small longitudinal height can be matched; when the operation area is provided with press keys, the required circuit board 15 is relatively thick or needs to have a larger longitudinal space to accommodate related accessories (such as the type configured with a spring), and in this case, the expansion bracket 12 with large longitudinal height can be matched. By configuring different specifications of the expansion bracket 12, different circuit boards 15 and operation structures can be matched, which can further enrich the models of the air fryer, and is beneficial to provide different models for different e-commerce platforms, thereby improving the application performance of the product.
[0048] As shown in Figure 2 , the top cover 11, the expansion bracket 12 and the body 10 are distributed from top to bottom, and the body 10 is the original structure. In order to improve the adaptability of the expansion bracket 12, the expansion bracket 12 can be processed according to the size and assembly structure of the top cover 11 and the body 10. The expansion bracket 12, the top cover 11 and the body 10 can be connected through a buckle structure, which is simple in structure and is beneficial to disassembly and assembly of the expansion bracket 12. In the preferred embodiment, the expansion bracket 12, the top cover 11 and the body 10 are connected through a buckle structure, as shown in Figures 2 to 4 , the top of the expansion bracket 12 is provided with a mounting surface 121, the mounting surface 121 is provided with a first clamping groove 122, and correspondingly, the top cover 11 is provided with a first buckle 111 matched with the first clamping groove 122. Further, the inner side wall of the expansion bracket 12 is provided with a second buckle 123 extending downward, and correspondingly, the body 10 is provided with a second clamping groove 104 matched with the second buckle 123. The buckle connection structure is simple in structure, easy to install, and makes different models of air fryers easy to assemble, which is beneficial to improve the assembly efficiency. Preferably, the first clamping groove 122 and the second buckle 123 are arranged in a staggered manner, which can reasonably utilize the space and ensure the structural strength of the expansion bracket 12 as a whole, thereby improving the durability.
[0049] As a preferred embodiment, the air fryer is provided with a first air inlet 13 and a second air inlet 14 communicating with the electric cavity 101. The first air inlet 13 is arranged on the body 10, and the second air inlet 14 is arranged between the expansion bracket 12 and the top cover 11.
[0050] In the case of adding the expansion bracket 12 to the fuselage 10, the internal space of the expansion bracket 12 and the original electrical cavity 101 of the fuselage 10 form an enlarged heat dissipation cavity. In order to ensure the heat dissipation effect of the motor 103 and other devices, the air fryer is provided with a first air inlet 13 and a second air inlet 14. Compared with the existing single air inlet, the air fryer can realize multi-position simultaneous air inlet, which is beneficial to increase the air inlet amount per unit time and improve the heat dissipation efficiency of the motor 103 and other devices, so as to ensure the service life of the motor 103 and other devices. Further, the first air inlet 13 and the second air inlet 14 are arranged at different heights, so that the whole machine can realize air inlet at different heights. This can not only avoid the increase of air resistance caused by the aggregation of air inlet and affect the air inlet efficiency, but also be beneficial to directly blow and heat dissipate the devices at the air inlet height and below, and further improve the heat dissipation effect.
[0051] As shown in Figure 1 , the first air inlet 13 and the second air inlet 14 are arranged in the vertical direction. When the whole machine is high, the fuselage 10 and the expansion bracket 12 can correspond to the air inlet, which can meet the heat dissipation demand of the internal space of the machine after being enlarged.
[0052] In order to further improve the heat dissipation effect, in one embodiment, the first air inlet 13 and the second air inlet 14 are arranged in the horizontal direction.
[0053] For example, the first air inlet 13 is arranged on the radial outer side of the second air inlet 14. This design can make the air inlet on the outer side flow along a longer path to cool more devices after air inlet, and the air inlet on the inner side is close to the devices in the center of the electrical cavity 101, which is beneficial to the rapid flow of the air on the surface of the devices to improve the heat dissipation efficiency and avoid the high temperature rise caused by the untimely heat dissipation to affect the performance and service life of the devices.
[0054] As shown in Figure 1 and Figure 6 , assuming that the motor 103 is arranged at the center position 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 motor 103. Therefore, the airflow of the first air inlet 13 can reach the surface of the motor 103 more quickly, which is beneficial to improve the heat dissipation efficiency of the motor 103.
[0055] In one embodiment, the first air inlet 13 is lower than the circuit board 15, and the second air inlet 14 is higher than the circuit board 15.
[0056] As shown in Figure 2As shown, the first air inlet 13 and the second air inlet 14 can be arranged at different heights to dissipate heat from both sides of the circuit board 15, thereby reducing the temperature of the circuit board 15 and improving its performance and service life. Preferably, the second air inlet 14 is arranged directly opposite the side of the circuit board 15, so that the airflow flowing from the second air inlet 14 can directly blow on the circuit board 15, achieving efficient heat dissipation.
[0057] As a preferred embodiment, the extension bracket 12 and the body 10 cooperatively form a mounting groove 125, the outer peripheral wall of the extension bracket 12 protrudes to form an upper edge 126 of the mounting groove 125, and the top of the body 10 protrudes outward relative to the bottom of the extension bracket 12 to form a lower edge 105 of the mounting groove 125. An annular decorative ring 16 is mounted in the mounting groove 125.
[0058] As shown in Figure 6 and Figure 7 the use of the body 10 to form the lower edge 105 of the mounting groove 125 can simplify the structure of the extension bracket 12, and the decorative ring 16 is limited by the upper edge 126 and the lower edge 105 of the mounting groove 125, which can prevent the decorative ring 16 from running up and down and affecting the aesthetics, improving the installation reliability. Moreover, due to the shielding effect of the upper edge 126 and the lower edge 105, the user's hand can be prevented from touching the edge of the decorative ring 16 in the case of a relatively sharp edge, thereby reducing the risk of scratching and improving the safety of use.
[0059] Specifically, the extension bracket 12 can be a plastic part, and the decorative ring 16 can be made of plastic, metal, or other materials, which can be set according to requirements, for example, a metal decorative ring 16 has better luster and is more aesthetically pleasing.
[0060] In one embodiment, the bottom of the decorative ring 16 is provided with an inwardly folded edge 161, which is inserted into the gap between the extension bracket 12 and the body 10.
[0061] As shown in Figure 7 by inserting the folded edge 161 into the gap between the extension bracket 12 and the body 10, the decorative ring 16 can be further prevented from running up and down, and the decorative ring 16 can be stably attached to the outer wall of the extension bracket 12, ensuring the aesthetics. In addition, the design of the folded edge 161 can prevent the hand from contacting the sharp edge of the decorative ring 16, thereby reducing the risk of installation.
[0062] As shown in Figure 5As shown, the bottom of the decorative ring 16 arranged at the rear side of the expansion bracket 12 is provided with a folded edge 161. In the case that the rear side of the machine body 10 is provided with an air outlet, the limitation of the decorative ring 16 at the rear side of the expansion bracket 12 can reduce the influence of the air flow on the decorative ring 16, so that the decorative ring 16 is prevented from moving upward, thereby ensuring the installation stability of the decorative ring 16. It can be understood that the folded edge 161 can be a non-connected structure such as a plurality of folded edges 161 arranged at intervals, or a continuous structure covering the entire length of the decorative ring 16, which is arranged as required and is not limited in the present application.
[0063] In one embodiment, the decorative ring 16 is formed by enclosing a long strip-shaped decorative piece, and the two ends of the decorative piece are connected by the elastic member 17.
[0064] As shown in Figure 4 and Figure 5 The decorative ring 16 is circumferentially arranged around the expansion bracket 12. In order to facilitate the installation of the decorative ring 16, the decorative ring 16 is formed by enclosing a long strip-shaped decorative piece, that is, one end of the decorative piece is positioned first when the decorative ring 16 is installed, then the decorative piece is attached around the expansion bracket 12, and finally the two ends of the decorative piece are fixed when the other end of the decorative piece is in place. The two ends of the decorative piece can be connected by the elastic member 17, and the deformation of the elastic member 17 can be used to make the decorative ring 16 always tightly attached to the expansion bracket 12, thereby improving the installation effect. In addition, the use of the elastic member 17 can also compensate for the assembly tolerance, so that the normal installation of the decorative ring 16 is not affected even if the length of the decorative ring 16 is slightly deviated. The elastic member 17 is, for example, a spring. Preferably, the expansion bracket 12 is provided with a shielding portion 127, and the two ends of the decorative piece and the elastic member 17 can be inserted into the inside of the shielding portion 127 and hidden, thereby improving the aesthetic appearance.
[0065] As a preferred embodiment, the machine body 10 is provided with a first air inlet 13 communicating with the electrical appliance cavity 101. The first air inlet 13 is arranged between the expansion bracket 12 and the machine body 10, that is, the first air inlet 13 is arranged at the junction of the expansion bracket 12 and the machine body 10. In this way, the decorative effect of the expansion bracket 12 can be used to weaken the visual sense of the first air inlet 13, thereby reducing the influence of the first air inlet 13 on the appearance of the whole machine and improving the aesthetic appearance of the machine body 10.
[0066] Preferably, the first air inlet 13 is arranged only at the rear side of the machine body 10 and is not directly visible to the user, thereby improving the visual experience of the user. In other embodiments, the first air inlet 13 can also be arranged at other positions circumferentially of the machine body 10, or the first air inlet 13 can be arranged circumferentially along the machine body 10, thereby increasing the air inlet amount and improving the heat dissipation efficiency of the device.
[0067] As a preferred embodiment, the top of the machine body 10 is provided with a top plate 106, and the top plate 106 abuts against the lower end of the circuit board 15.
[0068] AsFigure 2 As shown, the top plate 106 provides support for the circuit board 15, and when the user presses the keys of the operation area, the force is transmitted downward to effectively press the keys, preventing invalid operation caused by false pressing and affecting the hand feeling.
[0069] Further, the top plate 106 can be a hollow support, which provides support for the circuit board 15 and allows air flowing into the air fryer to flow into the body 10 through the hollow area to dissipate heat from the devices in the body 10. Alternatively, the top plate 106 can be provided with a vent for air flow.
[0070] As a preferred embodiment, the circuit board 15 is fixedly connected with the extension bracket 12 to form a module.
[0071] It can be understood that the modular design has many advantages, such as preventing parts from being lost during factory transportation and omitting assembly steps during use. Based on this, the circuit board 15 of the present application is fixedly connected with the extension bracket 12 to form a module. By forming a modular structure, the circuit board 15 and the extension bracket 12 can omit the installation process between the circuit board 15 and the extension bracket 12 when assembled with other structures of the air fryer, which can effectively improve the assembly efficiency of the whole machine. Moreover, the extension bracket 12 and the circuit board 15 form a module, and during the modification process from a mechanical model to an electronic model, only the module needs to be added to the mechanical model to realize the modification, which is convenient for switching different models on the production line.
[0072] The installation method of the circuit board 15 of the present application can be that the circuit board 15 is fixed on the top cover 11, or the circuit board 15 is fixed on the extension bracket 12, or the circuit board 15 is fixedly connected with the extension bracket 12, and the top cover 11 is further provided with a limiting structure for limiting the circuit board 15 to enhance the fixing stability of the circuit board 15.
