Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and in particular to a support frame, an electromagnetic heating plate, and a rice cooker. Background Technology

[0002] Rice cookers are common household appliances that use electromagnetic heating to cook food. The electromagnetic heating plate is a crucial component for this process. Currently, electromagnetic heating plates use either fully enclosed or recessed installations for the magnetic strip. Full enclosed installation involves injection molding a support frame around the magnetic strip, which then supports it. However, when the magnetic strip weakens, reducing the heating efficiency of the plate, the magnetic strip cannot be replaced individually, increasing maintenance costs. Recessed installation involves manufacturing the support frame first, then embedding the magnetic strip into it. However, current recessed installation methods cannot guarantee the stability of the magnetic strip within the support frame, making it prone to detaching. Utility Model Content

[0003] The purpose of this invention is to provide a support frame that uses a limiting buckle to confine the magnetic strip within the receiving cavity, thereby ensuring the stability of the magnetic strip during installation on the support frame.

[0004] Another objective of this invention is to provide an electromagnetic heating plate in which a magnetic strip is placed in the receiving cavity of the support frame to ensure the stability of the magnetic strip installation on the support frame.

[0005] Another objective of this invention is to provide a rice cooker that uses an electromagnetic heating plate for heating, thereby reducing maintenance costs.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Firstly, a support frame is provided, the support frame having a receiving cavity for receiving a magnetic strip, at least one side of the receiving cavity having a deformable wall, and the side of the deformable wall facing the receiving cavity having a limiting buckle for restricting the magnetic strip from sliding out of the port of the receiving cavity.

[0008] As an optional technical solution, the limiting buckle is located at the port of the receiving cavity.

[0009] As an optional technical solution, the other side wall of the receiving cavity is provided with a groove, which is directly opposite the limiting buckle.

[0010] As an optional technical solution, the side wall of the port of the receiving cavity is provided with a guide slope, which is used to guide the magnetic strip to slide into the receiving cavity.

[0011] As an optional technical solution, the limiting buckle is provided with the guide slope.

[0012] As an optional technical solution, deformation grooves are provided on both sides of the deformable wall.

[0013] As an optional technical solution, at least one side wall of the receiving cavity is provided with a clearance opening, which extends along the length direction of the receiving cavity.

[0014] As an optional technical solution, the support frame includes an inner support and several outer supports. The several outer supports are arranged at equal intervals around the periphery of the inner support. The outer supports extend radially along the inner support and are provided with the receiving cavity.

[0015] Secondly, an electromagnetic heating plate is provided, including a magnetic strip and a support frame as described above, wherein the magnetic strip is disposed in a receiving cavity of the support frame.

[0016] Thirdly, a rice cooker is provided, including the electromagnetic heating plate as described above.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides a support frame with a receiving cavity for accommodating a magnetic strip. At least one side of the receiving cavity is provided with a deformable wall, and a limiting buckle is provided on the side of the deformable wall facing the receiving cavity for limiting the magnetic strip from sliding out of the port of the receiving cavity.

[0019] When the magnetic strip needs to be inserted into the receiving cavity, the deformable wall is moved, causing it to elastically deform away from the cavity. The limiting buckle moves along with the deformable wall, increasing the port area of ​​the receiving cavity and facilitating the insertion of the magnetic strip. After the magnetic strip passes the limiting buckle, the deformable wall is released and returns to its original shape. The limiting buckle then confines the magnetic strip within the receiving cavity, preventing it from slipping out. When the magnetic strip needs to be removed from the receiving cavity, the deformable wall is moved again, causing it to elastically deform away from the cavity. The limiting buckle moves along with the deformable wall, increasing the port area of ​​the receiving cavity and facilitating removal. This new support frame facilitates the disassembly and installation of the magnetic strip, reducing maintenance costs. When the magnetic strip is in the receiving cavity, the limiting buckle confines it, preventing it from detaching from the support frame and ensuring its installation stability.

[0020] This utility model also provides an electromagnetic heating plate, which includes a magnetic strip and the support frame as described above, with the magnetic strip disposed in the receiving cavity of the support frame.

[0021] The limiting buckle confines the magnetic strip within the receiving cavity, preventing it from detaching from the support frame and ensuring its installation stability. Moving the deformable wall causes the limiting buckle to move, increasing the port area of ​​the receiving cavity, facilitating the removal and installation of the magnetic strip, and reducing maintenance costs.

[0022] This invention also provides a rice cooker, which includes the electromagnetic heating plate described above. When the magnetism of the magnetic strip weakens, the magnetic strip can be quickly replaced, reducing maintenance costs. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] like Figures 1 to 6 As shown, this embodiment provides a support frame 1, which has a receiving cavity 121 for receiving a magnetic strip 2. At least one side of the receiving cavity 121 has a deformable wall 122, and the side of the deformable wall 122 facing the receiving cavity 121 has a limiting buckle 123 for restricting the magnetic strip 2 from sliding out of the port of the receiving cavity 121.

[0037] When it is necessary to insert the magnetic strip 2 into the receiving cavity 121, the deformable wall 122 is moved, and the deformable wall 122 elastically deforms away from the receiving cavity 121. The limiting buckle 123 moves with the deformable wall 122, and the port area of ​​the receiving cavity 121 increases, making it easier to insert the magnetic strip 2 into the receiving cavity 121. After the magnetic strip 2 passes the limiting buckle 123, the deformable wall 122 is released, and the deformable wall 122 returns to its original shape. The limiting buckle 123 restricts the magnetic strip 2 in the receiving cavity 121, preventing the magnetic strip 2 from sliding out of the port of the receiving cavity 121. When it is necessary to remove the magnetic strip 2 from the receiving cavity 121, the deformable wall 122 is moved, and the deformable wall 122 elastically deforms away from the receiving cavity 121. The limiting buckle 123 moves with the deformable wall 122, and the port area of ​​the receiving cavity 121 increases, making it easier to remove the magnetic strip 2 from the receiving cavity 121. The support frame 1 of this utility model facilitates the disassembly and installation of the magnetic strip 2, reduces maintenance costs, and when the magnetic strip 2 is located in the receiving cavity 121, the limiting buckle 123 can restrict the magnetic strip 2 in the receiving cavity 121, prevent the magnetic strip 2 from detaching from the support frame 1, and ensure the installation stability of the magnetic strip 2 in the support frame 1.

[0038] In this embodiment, the magnetic strip 2 is a rectangular strip structure, the cross-section of the receiving cavity 121 is a square cross-section, and a deformable wall 122 is provided on one side of the receiving cavity 121. In some other embodiments, deformable walls 122 are provided on both sides of the receiving cavity 121.

[0039] In this embodiment, the cavity 121 is provided with a support wall 128 on one side of the deformable wall 122. The deformable wall 122 is connected to the support wall 128. When the magnetic strip 2 is installed in the cavity 121, a part of the magnetic strip 2 abuts against the support wall 128 and the other part of the magnetic strip 2 abuts against the deformable wall 122. The support wall 128 can improve the structural strength of the support frame 1.

[0040] In this embodiment, the limiting buckle 123 is located at the port of the receiving cavity 121. After the magnetic strip 2 passes over the limiting buckle 123, the deformable wall 122 can be restored to its original shape, which can make full use of the spatial volume of the receiving cavity 121.

[0041] In some other embodiments, the limiting buckle 123 is located inside the receiving cavity 121.

[0042] Optionally, the other side wall of the receiving cavity 121 is provided with a slot 124, which is directly opposite the limiting buckle 123. The slot 124 and the limiting buckle 123 are located on both sides of the receiving cavity 121. When the magnetic strip 2 is pushed into the receiving cavity 121 using an assembly tool, the limiting buckle 123 abuts against the assembly tool. The limiting buckle 123 drives the deformable wall 122 to move and deform in a direction away from the slot 124. The slot 124 avoids the assembly tool, ensuring that the assembly tool can completely push the magnetic strip 2 into the receiving cavity 121.

[0043] Optionally, the side wall of the port of the receiving cavity 121 is provided with a guide slope 125, which is used to guide the magnetic strip 2 to slide into the receiving cavity 121.

[0044] Optionally, the limit buckle 123 is provided with a guide slope 125.

[0045] When the magnetic strip 2 approaches the receiving cavity 121, the guide slope 125 plays a guiding and aligning role, ensuring that the magnetic strip 2 can be accurately installed into the receiving cavity 121.

[0046] In this embodiment, deformation grooves 126 are provided on both sides of the deformable wall 122. The two deformation grooves 126 and the deformable wall 122 are located on the same side of the receiving cavity 121. The deformation grooves 126 are provided between the deformable wall 122 and the adjacent side wall, which is beneficial to the deformation of the deformable wall 122.

[0047] Optionally, at least one side wall of the receiving cavity 121 is provided with a clearance opening 127, which extends along the length of the receiving cavity 121. The insertion depth of the magnetic strip 2 in the receiving cavity 121 can be observed through the clearance opening 127.

[0048] In this embodiment, the clearance opening 127 and the slot opening 124 are located on the same side of the receiving cavity 121.

[0049] In this embodiment, the support frame 1 includes an inner support 11 and a plurality of outer extension frames 12. The plurality of outer extension frames 12 are arranged at equal intervals around the periphery of the inner support 11. The outer extension frames 12 extend radially along the inner support 11 and are provided with receiving cavities 121.

[0050] Several outer frames 12 correspond one-to-one with several magnetic strips 2. Several magnetic strips 2 are arranged at equal intervals around the periphery of the inner support 11, which is conducive to forming a stable and consistent magnetic field. The outer frames 12 and magnetic strips 2 are arranged radially along the inner support 11, which matches the cylindrical shape of the rice cooker.

[0051] In this embodiment, there are four extension frames 12. In other embodiments, there are five, six or even more extension frames 12.

[0052] Optionally, the inner wall of the inner support 11 is provided with at least two limiting walls 111. The at least two limiting walls 111 are arranged at equal intervals around the central axis of the inner support 11. The limiting wall 111 is provided with a limiting part 112 on the side facing the central axis of the inner support 11. The limiting part 112 is used to be inserted into the slot of the coil disc.

[0053] Optionally, the limiting wall 111 is provided with relief grooves 113 on both sides, so that the limiting wall 111 can be elastically deformed.

[0054] Optionally, a hollow groove 129 is provided between the outer wall of the inner support 11 and the outer extension frame 12.

[0055] Optionally, a hollow groove 129 is provided between the limiting wall 111 and the extension frame 12.

[0056] This embodiment also provides an electromagnetic heating plate, which includes a magnetic strip 2 and a support frame 1 as described above. The magnetic strip 2 is disposed in the receiving cavity 121 of the support frame 1.

[0057] Specifically, the limiting buckle 123 can confine the magnetic strip 2 within the receiving cavity 121, preventing the magnetic strip 2 from detaching from the support frame 1 and ensuring the installation stability of the magnetic strip 2 on the support frame 1. When the deformable wall 122 is moved, the deformable wall 122 can drive the limiting buckle 123 to move, increasing the port area of ​​the receiving cavity 121, facilitating the disassembly and installation of the magnetic strip 2, and reducing maintenance costs.

[0058] This embodiment also provides a rice cooker, which includes the electromagnetic heating plate as described above. When the magnetism of the magnetic strip 2 weakens, the magnetic strip 2 can be quickly replaced, reducing maintenance costs.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
