Description
Technical Field
[0001] This application belongs to the field of household appliance technology, specifically relating to an air fryer. Background Technology
[0002] An air fryer generally includes a main body, a cooking chamber formed within the main body, a hot air assembly located within the main body and supplying high-temperature air into the cooking chamber, and a pot inside the cooking chamber for holding food. The high-temperature hot air generated when the hot air assembly is working heats the food inside the cooking chamber. The hot air comes into full contact with the food, and the food's surface moisture or the oil produced during the heating process creates a crispy texture, similar to being deep-fried.
[0003] To facilitate user observation of the cooking process inside the air fryer, at least a portion of the main body above the cooking cavity is typically made transparent, and a light is installed on it. There are generally three methods for installing the light in existing air fryers: one is to use a snap-fit structure on the lamp holder, with a matching mechanism on the reflector to secure the light; another is to have mounting holes on the lamp holder, using screws or other fasteners to fix the light to the reflector; and the third is to use a sheet metal bracket, mounting the lamp holder and light together, with the bracket fixed to the reflector. However, most existing lamp holders are made of ceramic, making it difficult to machine snap-fit features or mounting holes onto ceramic. Furthermore, significant impact during processing can easily cause the lamp holder to break, reducing product yield. When using sheet metal brackets to mount lighting fixtures, there are usually assembly gaps between the sheet metal brackets and the reflectors. These gaps can lead to light leakage, and when the light hits the top cover of the device, it can easily create localized light spots. This not only affects the visibility but also the product's appearance and reduces the user experience. Utility Model Content
[0004] This application provides an air fryer to solve the technical problem that in existing air fryers, light easily leaks through the assembly gap between the light and the reflector during operation, resulting in local light spots in the top cover area, which affects the user's observation effect.
[0005] The technical solution adopted in this application is as follows:
[0006] An air fryer includes a reflector, a light source, and a light holder. The light source is mounted on the reflector via the light holder. The light source includes a lamp holder and a lamp body disposed on the lamp holder. The light holder has a through cavity. The reflector has an opening. The light source passes through the cavity and the opening so that the lamp body extends below the reflector. The bottom of the light holder has an annular limiting rib surrounding the cavity. The limiting rib is embedded in the opening. The light holder has an abutting surface located on the outer periphery of the limiting rib and abutting against the outer surface of the reflector. The limiting rib and the abutting surface cooperate to form a light-shielding corner.
[0007] In this application, the bottom of the lamp holder is provided with an abutment surface that abuts against the outer surface of the reflector, and a limiting rib surrounding the accommodating cavity. The limiting rib and the abutment surface cooperate to form a light-shielding corner. Compared with the technical solution where the abutment surface is directly exposed in the light propagation path of the lamp body, the presence of the light-shielding corner in this application can effectively block the light from leaking from the assembly gap, avoiding the formation of local light spots in the top area of the air fryer. This makes the light in the cooking cavity more uniform and softer, and the user's vision is clearer when observing the cooking process. Strong light reflection or local overbrightness will not affect the judgment of the food's cooking status, thereby improving the user experience. Moreover, the design of the limiting rib and the formation of the light-shielding corner do not increase the extra volume of the air fryer, optimizing the spatial layout inside the air fryer and improving space utilization. In addition, the embedded design of the limiting rib can also provide coarse positioning for the lamp holder during the assembly process of the lamp holder and the reflector, thereby helping to improve the assembly efficiency of the lamp holder and the reflector.
[0008] The height of the limiting rib is greater than the thickness of the reflector, so that the limiting rib extends into the underside of the reflector.
[0009] If the limiting rib only extends a portion into the opening of the reflector, its height is insufficient, resulting in a small blocking area for the lamp body along its height direction and a short downward extension at the light-shielding corner. This fails to effectively block the light from the lamp, and some light will still leak through the assembly gap between the mating surface and the reflector. In this technical solution, the height of the limiting rib is greater than the thickness of the reflector, allowing it to extend below the reflector. This increases the blocking area of the rib along its height direction and lengthens the downward extension at the light-shielding corner, thus more effectively blocking the light and reducing the probability of light leakage through the assembly gap.
[0010] The inner diameter of the accommodating cavity is wider at the bottom and narrower at the top to form a light-shielding step within the accommodating cavity.
[0011] During operation, the lighting lamp emits light evenly in all directions. However, some light may propagate upwards and leak through the assembly gap between the lamp holder and the lamp base. In this technical solution, the inner diameter of the accommodating cavity is wider at the bottom and narrower at the top, thus forming a light-shielding step within the cavity. This light-shielding step blocks the upward-propagating light and reflects it back into the cooking cavity. This improves the illumination of the food inside the cooking cavity and reduces the probability of upward-propagating light leaking through the assembly gap between the lamp holder and the lamp base. From a structural perspective, the presence of the light-shielding step within the accommodating cavity increases the structural strength of the cavity sidewalls, reducing the probability of deformation or damage under external forces or high temperatures, and extending the lifespan of the lamp holder.
[0012] The light-shielding step has a reflective surface that extends from bottom to top toward the centerline of the accommodating cavity.
[0013] The lamp body is located inside the reflector, which houses a hot air assembly for supplying hot air into the cooking cavity to cook food. Both the lamp body's own heat generation during operation and the hot air circulation within the cooking cavity cause the lamp body to heat up. If the lamp body cannot dissipate heat in time, it will affect the stability and lifespan of its operation. Therefore, a heat dissipation gap needs to be designed between the inner wall of the lamp holder's housing cavity and the lamp base to facilitate heat dissipation. This technical solution designs the reflective surface of the light-shielding step as an inclined design extending from bottom to top towards the centerline of the housing cavity. Compared to a lateral extension design of the reflective surface, this minimizes the occupancy of the light-shielding step and reflective surface in the heat dissipation gap. This ensures timely heat dissipation of the lamp body while reflecting light towards the centerline of the housing cavity, minimizing the amount of light entering the heat dissipation gap. This reduces the probability of light leakage from the heat dissipation gap and assembly gap between the lamp holder and the lamp base, preventing the formation of localized light spots on the top of the air fryer.
[0014] The lamp holder has an extension that extends into the accommodating cavity, and there is a heat dissipation gap between the extension and the inner wall of the accommodating cavity.
[0015] The lamp body is located inside a reflector, which houses a hot air assembly for supplying hot air into the cooking cavity to cook food. Both the lamp body's own heat generation during operation and the hot air circulation within the cooking cavity cause the lamp body to heat up. Excessive temperature can accelerate light decay and even lead to lamp holder and lamp body malfunctions. In this technical solution, a heat dissipation gap exists between the lamp holder's extension and the inner wall of the accommodating cavity. The heat generated by the lamp holder and lamp body during operation can be dissipated through this gap, helping to maintain the lamp body within a suitable temperature range. This improves the lamp body's brightness and luminous efficacy, ensures stable lighting effects, reduces lamp body and lamp holder malfunctions caused by overheating, enhances product reliability and stability, and extends the lifespan of the lamp holder and lamp body.
[0016] The lamp holder has a positioning part that seals and abuts against the upper end of the accommodating cavity. The positioning part includes a main body and a light-shielding protrusion extending laterally outward from the main body. The light-shielding protrusion covers the top of the heat dissipation gap.
[0017] In this technical solution, the positioning part seals and abuts against the upper end of the accommodating cavity, ensuring accurate positioning of the lamp holder during installation. This guarantees proper alignment between the lamp holder and the accommodating cavity, preventing light leakage or instability caused by installation deviations. Furthermore, the positioning part provides stable support for the lamp holder, preventing it from loosening or shifting during air fryer operation, thus ensuring the stability and reliability of the lighting. The light-shielding protrusion covers the heat dissipation gap, effectively blocking light leakage and preventing the formation of localized light spots in the top cover area. This results in more uniform and softer lighting within the cooking cavity, improving the user's viewing experience. Although the light-shielding protrusion covers the heat dissipation gap, its design does not completely seal it, allowing air circulation for heat dissipation from the lamp holder and lamp body.
[0018] The lamp holder has a positioning part that seals and abuts against the upper end of the accommodating cavity. The positioning part includes a terminal for the lead wire of the lamp body to be led out and a mounting end for mounting with the lamp bracket. The upper surface of the terminal and the upper surface of the mounting end have a height difference.
[0019] If the wiring terminals of the lamp holder are flush with the mounting terminals, the lead wires may be damaged during the assembly of the lamp holder and lamp bracket due to misoperation (such as the screw head pinching the lead wire or the screwdriver puncturing the insulation layer of the lead wire). In this technical solution, the upper surface of the wiring terminals of the lamp holder and the upper surface of the mounting terminals have a height difference, which effectively reduces the possibility of operator misoperation damaging the lamp body lead wires during assembly and avoids leakage.
[0020] The lamp holder has a positioning part that seals and abuts against the upper end of the accommodating cavity. The positioning part is provided with a through positioning hole. The lamp bracket is provided with a positioning post. The positioning post passes through the positioning hole from bottom to top and its upper end extends out of the positioning hole. The air fryer also includes a fastener. The fastener includes a limiting part. The fastener is fixed to the positioning post from top to bottom and the positioning part clamps and fixes the positioning part to the lamp bracket through the limiting part.
[0021] Existing lamp holders are generally made of ceramic. If fasteners or other connectors used to link the lamp holder and lamp bracket directly impact the lamp holder during installation, the impact force may be too great and cause the lamp holder to crack, increasing assembly difficulty. In this technical solution, the positioning post of the lamp bracket passes through the positioning hole of the lamp holder and extends above the positioning hole. When the lamp bracket and lamp holder are assembled using fasteners, the extended design of the positioning post allows its upper end to bear the impact force first, preventing the fastener from pressing down further. This effectively protects the lamp holder and prevents it from being crushed.
[0022] The outer periphery of the positioning post is provided with several reinforcing ribs, and the top of the reinforcing ribs abuts against the positioning part.
[0023] The reinforcing ribs on the outer periphery of the positioning post in this technical solution not only improve the structural strength of the positioning post but also increase the support area for the lamp holder, thereby enhancing the stability of the lamp holder after installation. Furthermore, during the assembly of the lamp holder and lamp bracket, if excessive torque is applied to the fasteners, causing the positioning post to deform under pressure, the upper end of the positioning post and the reinforcing ribs can work together to provide extensive support for the positioning part of the lamp holder, distributing the stress on the positioning part and reducing the probability of the lamp holder cracking due to tightening force.
[0024] The cross-section of the opening is non-circular to restrict the rotation of the lamp holder along the circumferential direction of the opening.
[0025] In this technical solution, the cross-section of the reflector's opening is a non-circular structure, which can provide precise guidance during the assembly process of the lamp bracket and the reflector, playing a role in installation positioning and auxiliary limiting. This helps to improve assembly efficiency and accuracy, and prevents the lamp bracket from deviating from the preset position, which would cause assembly gaps in some areas between the lamp bracket and the reflector, and thus cause light leakage from the lamp body.

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, an air fryer includes a reflector 5, a lamp, and a lamp holder 1. The lamp is mounted on the reflector 5 via the lamp holder 1. The lamp includes a lamp holder 3 and a lamp body 4 disposed on the lamp holder 3. The lamp holder 1 has a through cavity 13. The reflector 5 has a through opening 51. The lamp passes through the cavity 13 and the through opening 51 so that the lamp body 4 extends into the underside of the reflector 5. The bottom of the lamp holder 1 has an annular limiting rib 11 surrounding the cavity 13. The limiting rib 11 is embedded in the through opening 51. The lamp holder 1 has an abutment surface 12 located on the outer periphery of the limiting rib 11 and abutting against the outer surface of the reflector 5. The limiting rib 11 and the abutment surface 12 cooperate to form a light-shielding corner.
[0048] In this application, the bottom of the lamp holder 1 is provided with an abutment surface 12 that abuts against the outer surface of the reflector 5, and a limiting rib 11 surrounding the accommodating cavity 13. The limiting rib 11 and the abutment surface 12 cooperate to form a light-shielding corner. Compared with the technical solution where the abutment surface is directly exposed in the light propagation path of the lamp body, the presence of the light-shielding corner in this application can effectively block the light from leaking from the assembly gap, avoid the formation of local light spots in the top cover area of the air fryer, and make the light in the cooking cavity more uniform and softer. When the user observes the cooking process, the vision is clearer, and the judgment of the food cooking status will not be affected by strong light reflection or local overbrightness, thereby improving the user experience. Moreover, the design of the limiting rib 11 and the formation of the light-shielding corner do not increase the extra volume of the air fryer, optimize the spatial layout inside the air fryer, and improve space utilization. In addition, the embedded design of the limiting rib 11 can also provide coarse positioning for the lamp bracket 1 during the assembly process of the lamp bracket 1 and the reflector 5, thereby helping to improve the assembly efficiency of the lamp bracket 1 and the reflector 5.
[0049] If the limiting rib 11 only extends a portion into the opening 51 of the reflector 5, the height of the limiting rib 11 is insufficient, resulting in a small blocking area of the lamp body 4 along the height direction, and a short downward extension of the light-shielding corner, which cannot effectively block the light from the lighting lamp. Some light will still leak through the assembly gap between the contact surface 12 and the reflector 5. Therefore, as a preferred embodiment of this application, such as Figure 2 and Figure 3 As shown, the height of the limiting rib 11 is greater than the thickness of the reflector 5, so that the limiting rib 11 extends into the underside of the reflector 5. This arrangement increases the blocking area of the limiting rib 11 on the lamp body 4 along the height direction, and the downward extension of the blocking corner is longer, which can more effectively block light and reduce the probability of light leakage from the assembly gap.
[0050] To further improve the light-shielding effect on the lamp body 4, this application may adopt any of the following embodiments;
[0051] Implementation method one: such as Figure 3As shown, the inner diameter of the accommodating cavity 13 is larger at the bottom and smaller at the top to form a light-shielding step 14 inside the accommodating cavity 13.
[0052] During operation, the lighting lamp emits light evenly in all directions. However, some light may propagate upwards and leak through the assembly gap between the lamp holder 1 and the lamp base 3. In this first embodiment, the inner diameter of the accommodating cavity 13 is wider at the bottom and narrower at the top, thus forming a light-shielding step 14 within the cavity. This light-shielding step 14 blocks the upward-propagating light and reflects it back into the cooking cavity, improving the illumination of the food inside and reducing the probability of upward-propagating light leaking through the assembly gap between the lamp holder 1 and the lamp base 3. From a structural perspective, the presence of the light-shielding step 14 within the accommodating cavity 13 increases the structural strength of the sidewalls of the cavity 13, reducing the probability of deformation or damage under external forces or high temperatures, and extending the service life of the lamp holder 1.
[0053] The lamp body 4 is located inside the reflector 5, which contains a hot air assembly for supplying hot air into the cooking cavity to cook food. Both the heat generated by the lamp body 4 itself during operation and the hot air circulation within the cooking cavity will cause the lamp body 4 to heat up. If the lamp body 4 fails to dissipate heat in time, it will affect the stability and lifespan of its operation. Therefore, a heat dissipation gap 2 needs to be designed between the inner wall of the receiving cavity 13 of the lamp holder 1 and the lamp base 3 to facilitate heat dissipation of the lamp body 4; that is, a heat dissipation gap 2 needs to exist between the inner wall of the receiving cavity 13 and the outer wall of the lamp base 3. However, the existence of the heat dissipation gap 2 also provides a channel for light leakage. Therefore, the specific configuration of the light-shielding step 14 in this embodiment can be any one of the following embodiments:
[0054] Example 1: This example 1 is not illustrated. In this example 1, the light-shielding step has a reflective surface that is fixed to the inner wall of the accommodating cavity and extends laterally toward the centerline of the accommodating cavity. The laterally extending reflective surface minimizes the size of the heat dissipation gap and reduces the amount of light leakage.
[0055] Example 2: Figure 3 As shown, the light-shielding step 14 has a reflective surface 141 extending upwards towards the centerline of the receiving cavity 13. In this embodiment 2, by designing the reflective surface 141 of the light-shielding step 14 to be inclined from bottom to top towards the centerline of the receiving cavity 13, compared with the lateral extension design of the reflective surface, the occupancy of the light-shielding step 14 and the reflective surface 141 on the heat dissipation gap 2 can be minimized. This ensures timely heat dissipation of the lamp body 4 and reflects the light towards the centerline of the receiving cavity 13, so that as little light as possible enters the heat dissipation gap 2, reducing the probability of light leakage from the heat dissipation gap 2 and assembly gap between the lamp bracket 1 and the lamp holder 3, and preventing the formation of local light spots in the top cover area of the air fryer.
[0056] Embodiment Two: This embodiment two is not illustrated. In this embodiment two, the lamp holder has an extension that extends into the receiving cavity, and the outer peripheral wall of the extension is provided with a light-shielding part that extends toward the inner wall of the receiving cavity. The light-shielding part can extend laterally, or it can extend from bottom to top toward the inner wall of the receiving cavity to form a reflective surface on the light-shielding part.
[0057] As a preferred embodiment of this application, such as Figure 3 As shown, the lamp holder 3 has an extension 33 that extends into the receiving cavity 13, and a heat dissipation gap 2 exists between the extension 33 and the inner wall of the receiving cavity 13. The heat generated by the lamp holder 3 and the lamp body 4 during operation can be dissipated through the heat dissipation gap 2, helping to maintain the lamp body 4 within a suitable temperature range, thereby improving the brightness and luminous efficacy of the lamp body 4, ensuring the stability of the lighting effect, reducing malfunctions of the lamp body 4 and lamp holder 3 due to overheating, improving product reliability and stability, and extending the service life of the lamp holder 3 and lamp body 4.
[0058] Furthermore, to improve heat dissipation, the upper part of the lamp bracket 1 is provided with an enlarged gap portion that communicates with the heat dissipation gap 2 and expands outward along the lamp bracket 1.
[0059] As a preferred embodiment of this implementation, such as Figure 6 and Figure 9 As shown, the lamp holder has a positioning part 31 that seals and abuts against the upper end of the accommodating cavity 13. The positioning part 31 includes a main body and a light-shielding protrusion 32 extending laterally outward from the main body, covering the heat dissipation gap 2. In this embodiment, the positioning part 31 seals and abuts against the upper end of the accommodating cavity 13, enabling the lamp holder 3 to be accurately positioned during installation, ensuring proper alignment between the lamp holder 3 and the accommodating cavity 13, avoiding light leakage or instability caused by installation deviations. Moreover, the positioning part 31 provides stable support for the lamp holder 3, making it less prone to loosening or displacement during the operation of the air fryer, ensuring the stability and reliability of the lighting. The light-shielding protrusion 32 covers the heat dissipation gap 2, effectively blocking light leakage from the heat dissipation gap 2, preventing the formation of local light spots in the top cover area, making the light in the cooking cavity more uniform and softer, and improving the user's observation effect. Although the light-shielding protrusion 32 covers the heat dissipation gap 2, its design does not completely seal the heat dissipation gap 2, still allowing air circulation, which facilitates heat dissipation of the lamp holder 3 and the lamp body 4.
[0060] Preferably, to minimize the weight of the lamp holder 3, such as Figure 9 As shown, a light-shielding protrusion 32 is only provided in a localized area of the main body, so that the downward projection of the light-shielding protrusion 32 can cover the heat dissipation gap 2 and prevent light from leaking out of the heat dissipation gap 2. Furthermore, as... Figure 9 As shown, the upper part of the light-shielding protrusion 32 is recessed downward to form a pit, thereby further achieving the purpose of material reduction and weight reduction.
[0061] As a preferred embodiment of this application, such as Figure 6 As shown, the lamp holder 3 has a positioning part 31 that seals and abuts against the upper end of the receiving cavity 13. The positioning part 31 includes a terminal 311 for the lead wire of the lamp body 4 to be led out, and a mounting end 312 for mounting with the lamp bracket 1. The upper surface of the terminal 311 and the upper surface of the mounting end 312 have a height difference. If the terminal 311 of the lamp holder 3 is flush with the mounting end 312, the lead wire may be damaged due to misoperation (such as the screw head pinching the lead wire or the screwdriver puncturing the insulation layer outside the lead wire) during the assembly of the lamp holder 3 and the lamp bracket 1. In this embodiment, the upper surface of the terminal 311 of the lamp holder 3 has a height difference with the upper surface of the mounting end 312, which can effectively reduce the possibility of operator misoperation damaging the lead wire of the lamp body 4 during the assembly process and avoid leakage.
[0062] In one embodiment, the terminal is recessed relative to the mounting end, so that the upper surface of the terminal is lower than the upper surface of the mounting end, thus creating a height difference.
[0063] In another embodiment, such as Figure 6 and Figure 9 As shown, the mounting end 312 is recessed relative to the wiring end 311, so that the upper surface of the wiring end 311 is higher than the upper surface of the mounting end 312, thus creating a height difference.
[0064] Existing lamp holders 3 are generally made of ceramic. If fasteners or other connecting parts used to connect the lamp holder 3 and the lamp bracket 1 directly hit the lamp holder 3 during installation, the lamp holder 3 may crack under significant impact, increasing the difficulty of assembly. Therefore, as a preferred embodiment of this application, such as Figure 6 and Figure 7 As shown, the lamp holder 3 has a positioning part 31 that seals and abuts against the upper end of the accommodating cavity 13. The positioning part 31 is provided with a through positioning hole 34. The lamp bracket 1 is provided with a positioning post 15, which passes through the positioning hole 34 from bottom to top and extends out of the positioning hole 34 at its upper end. The air fryer also includes a fastener, which includes a limiting part. The fastener is fixed to the positioning post 15 from top to bottom and clamps and fixes the positioning part 31 to the lamp bracket 1 through the limiting part. The fastener can be, for example, a screw. In this embodiment, the positioning post 15 of the lamp bracket 1 passes through the positioning hole 34 of the lamp holder 3 and extends above the positioning hole 34. When the lamp bracket 1 and the lamp holder 3 are assembled using the fastener, due to the extensible design of the positioning post 15, the upper end of the positioning post 15 first bears the impact force and prevents the fastener from continuing to press down, thereby effectively protecting the lamp holder 3 and preventing the lamp holder 3 from being crushed.
[0065] Preferably, the height difference H between the upper surface of the positioning post 15 and the upper surface of the mounting end 312 of the positioning part 31 satisfies: 0.5mm≤H≤1.5mm. This setting can improve the fixing effect of the lamp holder 3 after it is assembled in place, and also prevent the lamp holder 3 from moving up and down significantly.
[0066] As a preferred embodiment of this implementation, such as Figure 4 , Figure 5 and Figure 8 As shown, the lower part of the positioning post 15 is provided with a first mounting hole 17 coaxially arranged with the positioning post 15, and the reflector 5 is provided with a second mounting hole 52. The lamp holder 3 is installed on the reflector 5 by fasteners passing through the second mounting hole 52 and the first mounting hole 17 sequentially from bottom to top. Compared with the technical solution of separately setting multiple positioning posts, with different positioning posts used to fix the lamp holder and to install the lamp bracket on the reflector, the lamp holder 3 in this embodiment shares the positioning post 15 at both ends. This can reduce the installation space occupied by the lamp holder 3 and the lighting lamp, make full use of the redundant space inside the air fryer, achieve a compact structural arrangement, and help save materials and reduce costs.
[0067] As a preferred embodiment of this implementation, such as Figure 6 and Figure 7 As shown, the outer periphery of the positioning post 15 is provided with several reinforcing ribs 16, and the top of the reinforcing ribs 16 abuts against the positioning part 31. In this embodiment, the setting of the reinforcing ribs 16 on the outer periphery of the positioning post 15 not only improves the structural strength of the positioning post 15, but also increases the support area for the lamp holder 3, thereby improving the stability of the lamp holder 3 after installation. Moreover, during the assembly of the lamp holder 3 and the lamp bracket 1, if the torque of tightening the fasteners is too large and causes the positioning post 15 to be squeezed and deformed, the upper end of the positioning post 15 and the reinforcing ribs 16 can work together to provide large-scale support for the positioning part 31 of the lamp holder 3, disperse the force on the positioning part 31 of the lamp holder 3, and reduce the probability of the lamp holder 3 being crushed by the tightening force.
[0068] As a preferred embodiment of this application, such as Figure 4 As shown, the cross-section of the opening 51 is non-circular to limit the rotation of the lamp holder 1 along the circumferential direction of the opening 51. For example, the cross-section of the opening 51 is elliptical; or, for example, the cross-section of the opening 51 is rectangular. The non-circular cross-section of the opening 51 of the reflector 5 can provide precise guidance during the assembly process of the lamp holder 1 and the reflector 5, playing a role in installation positioning and auxiliary limiting, thereby helping to improve assembly efficiency and assembly accuracy, and preventing the lamp holder 1 from deviating from the preset position, which would cause assembly gaps in some areas between the lamp holder 1 and the reflector 5, and thus cause light leakage from the lamp body 4.
