Description

Technical Field

[0001] This utility model relates to the field of cooking appliance assembly technology, and in particular to inner lining components and air fryers. Background Technology

[0002] In the prior art, the inner lining assembly is generally made of a circular inner lining plate. This assembly causes the inner pot and the inner lining to collide with each other along the length of the pot, resulting in a large material loss.

[0003] Furthermore, for micro switches, assembly typically requires the use of screws or similar materials, which increases assembly costs and time. Utility Model Content

[0004] The purpose of this invention is to provide an inner liner assembly and an air fryer to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] On the one hand, the inner lining assembly includes an inner lining member forming a semi-enclosed cavity. The inner lining member includes an inner lining portion located on the front side of the pot body and forming a bearing surface. The inner lining portion has mounting portions extending vertically at both ends. The inner wall of the mounting portion is provided with a first mounting groove and a second mounting groove from top to bottom. The inner lining extends upward in a partial manner to form a switch bracket, and a positioning cavity for a micro switch is formed on the switch bracket; Both the inner lining and the assembly parts are made of plastic.

[0007] Furthermore, the second assembly groove is provided with a guide groove near the inner lining, and the first assembly groove and the second assembly groove form opposite assembly directions.

[0008] Furthermore, from the inner lining to the second assembly groove, the guide groove is an inclined groove whose height gradually increases.

[0009] Furthermore, a partial encapsulation cavity for a micro switch is formed at the bottom of the switch bracket, and the partial encapsulation cavity extends upward to form a limiting cavity.

[0010] Furthermore, it also includes a cover plate placed on top of the limiting cavity, and the top of the limiting cavity is provided with a locking element that forms downward pressure inward and matches the cover plate.

[0011] Furthermore, the cover plate forms an L-shaped structure that covers the top of the micro switch and is misaligned with the trigger part in the micro switch.

[0012] Furthermore, the lengths of the first and second assembly slots formed by the assembly part are one-fifth to one-third of the length of the inner pot.

[0013] Furthermore, several stepped structures are formed on the outer side of the assembly part, and the distance between the stepped structures and the assembly part gradually increases from top to bottom.

[0014] On the other hand, the air fryer includes a top cover and an inner pot, and also includes a liner assembly as described in any one of the above, wherein the top cover and the inner pot are assembled via the first assembly slot and the second assembly slot, respectively.

[0015] Furthermore, the outer cover has several ventilation holes forming an exhaust area, and the exhaust area is provided near several stepped structures on the assembly part.

[0016] The beneficial effects of this utility model are as follows: In this invention, a liner formed by a semi-enclosed cavity is selected. Its assembly part is matched with the front side of the pot body, and then the assembly grooves on both sides form a part for guiding assembly, thereby shortening the contact length with the inner pot as a whole, and thus reducing the wear length.

[0017] In this invention, by selecting plastic parts, a flexible yet rigid assembly method is achieved. Compared to a hard-on-hard method, this reduces wear, extends the product's lifespan, and is more compatible with the inner pot in the future.

[0018] In this invention, the inner lining extends directly to form a switch bracket for clamping the micro switch. In this case, an elastic plastic sheet can be used to form the switch bracket, which simplifies assembly, reduces tooling, lowers costs, and improves efficiency. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0021] See attached document Figure 1-4 As shown, the inner liner assembly 100 in this embodiment includes an inner liner 110 forming a semi-enclosed cavity. The inner liner 110 includes an inner liner portion located on the front side of the pot body and forming a bearing surface. Assembly portions 120 extend vertically from both ends of the inner liner portion. The inner wall of the assembly portion 120 is provided with a first assembly groove 121 and a second assembly groove 122 from top to bottom. Here, the pot body is generally an inner pot, and the inner liner is generally assembled with the inner pot. In the prior art, the inner liner is generally made of metal sheet and then various assembly portions are directly added. However, the inner pot and the outer cover are also made of metal. Furthermore, during assembly, hard-on collisions and wear are prone to occur, reducing service life. For some manufacturers with high requirements, it is difficult to meet their needs. Moreover, excessive wear will also result in worn surfaces on the surface, damaging the appearance and affecting the user experience. In this embodiment, a liner component 100 formed by a semi-enclosed cavity is selected. Its assembly part fits with the front side of the pot body, and the assembly grooves on both sides form part of the guiding assembly, thereby shortening the contact length with the inner pot as a whole, thus reducing the wear length. The overall cost and weight of this liner component are significantly reduced compared to the previous disc-shaped one, thus lowering the cost.

[0022] Compared to the assembly method using screws and holes, in this embodiment, the inner lining extends upwards to form a switch bracket 130, and a locking cavity for a micro switch 131 is formed on the switch bracket 130; in this case, assembly can be carried out directly by locking, and the head cover and other parts will also be partially protected and limited from the top, thus meeting the requirements for use.

[0023] To minimize wear and reduce the impact on appearance, in this embodiment, both the inner lining and the assembly part 120 are made of plastic. Plastic parts are elastic and provide a soft-hard fit with the metal, minimizing wear. Furthermore, during assembly, the user only comes into contact with the softer layer, rather than constantly contacting the metal layer, which also protects the user. If the assembly groove were a metal groove, it could easily scratch the user.

[0024] Referring to the accompanying drawings, it is clearly visible that in this embodiment, to facilitate subsequent assembly of the inner pot, a guide groove 123 is provided near the inner liner portion in the second assembly groove 121, and the first assembly groove 121 and the second assembly groove 122 form opposite assembly directions. Therefore, during assembly, the inner pot can be assembled from front to back, while the cap can be assembled from back to front. Furthermore, the protrusions on the top of the cap will not interfere with or collide with the front inner liner 110, improving assembly safety.

[0025] Specifically, from the inner lining to the second assembly groove 122, the guide groove 123 is an inclined groove with a gradually increasing height. Thus, from front to back, the guide groove 123 guides the lower-position structure to complete the assembly.

[0026] To protect the micro switch, a partial enclosure cavity for the micro switch 131 is formed at the bottom of the switch bracket 130, and the partial enclosure cavity extends upward to form a limiting cavity. Due to the setting of the limiting cavity, at least one-third of the bottom of the micro switch 131 is covered. Then, an elastic plastic sheet or the like constitutes the switch bracket 130, improving the robustness and stability of the assembly.

[0027] To further secure the switch and isolate it from airflow above, thereby improving its lifespan, a cover plate 132 is included on top of the limiting cavity. A locking member 133, which exerts downward pressure inward and matches the cover plate 132, is located on top of the limiting cavity. In this embodiment, the cover plate 132, in conjunction with the locking member 133, is fixedly positioned above the limiting cavity. Together with the limiting cavity, the cover plate 132 forms a larger enclosed and fixed cavity for the micro switch 131, ensuring stable assembly even under prolonged shaking.

[0028] In this embodiment, the cover plate 132 forms an L-shaped structure that covers the top of the micro switch 131 and is misaligned with the trigger part of the micro switch 131. This L-shaped structure provides close protection for the micro switch 131 in both horizontal and vertical directions, while the misalignment with the trigger part ensures that its control over the structures inside the cover is not affected, achieving multiple benefits.

[0029] Preferably, to ensure stable assembly of the inner pot, its assembly length should not be too short. Therefore, the length of the first assembly groove 121 and the length of the second assembly groove 122 formed by the assembly part 120 are one-fifth to one-third of the length of the inner pot. If it is less than one-fifth, there is a concern that the inner pot may not be able to support it and may fall off easily. If it is too large, it will be similar to the prior art, increasing costs and failing to achieve the effect of both reducing costs and ensuring assembly.

[0030] Furthermore, several stepped structures 140 are formed on the outer side of the assembly part 120. From top to bottom, the distance between the stepped structures 140 and the assembly part 120 gradually increases. The stepped structures 140 are further outward, and then they are assembled with the outer cover or insulation cover, etc. The stepped structures not only create a good clearance space, but also create a flow space for airflow, etc., achieving multiple benefits.

[0031] In this embodiment, the inner liner 110 may also be provided with a stop or the like, so that the inner pot 300 can only be in a set position and cannot continue to move forward. On the outer side of the assembly part 120, an assembly groove may also be provided. The second assembly groove 122 and the first assembly groove 121 are horizontal grooves, and the bottom extends downward to form a reinforcing rib, thereby increasing the strength of the entire inner liner assembly 100.

[0032] See attached document Figure 1-7 As shown, when the aforementioned inner liner assembly is used in an air fryer, it also includes a top cover 200, an inner pot 300, and an outer cover 400. The inner liner assembly 100 is then positioned between the inner pot 300 and the top cover 200. The top cover 200 and the inner pot 300 are then assembled via the first assembly groove 121 and the second assembly groove 122, respectively. At this point, the upper and lower assembly is completed using a simple semi-enclosed inner liner, forming the entire large pot structure. The inner pot 300 is assembled from front to back via the guide groove 123 at the second assembly groove 122, while the top cover 200 is assembled from back to front via the first assembly groove 121, thus completing the initial assembly of the top cover 200 and the inner pot 300.

[0033] In this embodiment, since the inner pot 300 is continuously heated, heat enters between the inner pot 300 and the outer cover 400, as well as between the head cover 200 and the outer cover 400. Therefore, some heat needs to be released through ventilation areas. Thus, a ventilation area 410 is formed on the outer cover 400 by several ventilation holes. This ventilation area 410 is located near the stepped structures 140 on the assembly part 120. Alternatively, it can be located near the heating element 210 in the head cover 200, allowing heat from the heating element 210 to be released through the ventilation area 410, thus preventing heat accumulation.

[0034] In this embodiment, the outer cover 400 is an inverted U-shape, providing partial protection for the top of the cover 200 and the outer side of the inner pot 300. The cover 200 is also an inverted U-shape, and the inner pot 300 is positioned on both sides. Support blocks 220 are provided on the inner wall of the cover 200, with the two support blocks 220 positioned rearwards. Part of the inner pot 300 is housed in the second mounting groove 122, and the rear portion is supported on both sides by the two support blocks 220. In this embodiment, the cover 200 can function as a reflector for heat reflection.

[0035] In this embodiment, an L-shaped base 420 is also provided in the outer cover 400, and a support foot 430 is provided on the base 420 to support the inner pot 300, thereby assisting the assembly groove to complete the assembly of the inner pot 300. In this embodiment, one support foot 430 and a support block 220 can be provided, or both can be provided simultaneously.

[0036] In this embodiment, the use of a semi-enclosed lining greatly improves the overall assembly efficiency and saves costs.
