Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical assembly, and in particular to an assembly structure and a rice cooker. Background Technology
[0002] With the development of electromagnetic induction technology, it is increasingly being used in more devices, especially in the field of home appliances. Currently, a type of smart rice cooker (i.e., an IH rice cooker) utilizing electromagnetic induction heating technology has emerged on the market. Its core advantage lies in its precise temperature control and efficient heating, significantly improving the taste of rice. However, when using electromagnetic heating, the high-frequency magnetic field generated by the current in an IH rice cooker may penetrate the outer shell, posing a safety hazard. Therefore, a radiation shield is currently installed inside the rice cooker. This shield is typically installed at the bottom of the rice cooker and uses highly permeable magnetic materials (such as silicon steel sheets or ferrite) to absorb or reflect the leaked magnetic field, reducing the radiation intensity to within a safe threshold. The radiation shield also provides structural isolation and thermal protection.
[0003] In existing IH rice cookers, to simplify the assembly of the radiation shielding plate, a flexible snap-fit structure is usually designed on the base. The radiation shielding plate and the base are fixedly connected by the snap-fit. However, after the radiation shielding plate and the base are assembled, there is a gap at the assembly position. In addition, there are manufacturing tolerances in the manufacturing process of the base and the radiation shielding plate. The assembly method described above can lead to the problem of loose assembly of the radiation shielding plate. Since the natural frequency of the radiation shielding plate differs from the resonant frequency of the winding coil by less than 5%, the radiation shielding plate will produce resonance and abnormal noise under the high-frequency alternating magnetic field of the winding coil, thus affecting the user experience.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0039] Reference Figures 1 to 14 As shown, this invention demonstrates an embodiment of the assembly structure and rice cooker of this utility model. The assembly structure includes a base 1 and a radiation shielding plate 2. The base 1 is provided with at least two first slots 11, which pass through the top and bottom ends of the base 1. The radiation shielding plate 2 is located at the top end of the base 1 and is provided with the same number of first buckles 21 as the first slots 11. During assembly, one end of the first buckle 21 passes through the first slot 11 from top to bottom and is bent and pressed against the outer side of the bottom end of the base 1.
[0040] Specifically, IH (induction heating) rice cookers directly heat the iron-based inner pot using a high-frequency alternating magnetic field. Combined with a multi-segment temperature control algorithm, they simulate a cooking curve similar to that of a wood-fired stove, optimizing rice quality from both physical heating and chemical transformation perspectives. Compared to traditional resistance heating technology, their thermal efficiency and temperature control accuracy are significantly improved. However, with the increase in power density (typically reaching 1000-2000W) and the application of high-frequency magnetic fields (20-40kHz), the equipment needs to balance electromagnetic shielding safety and structural stability. Therefore, the base 1 of the IH rice cooker must support the electromagnetic coil, the radiation shielding plate 2, and the inner pot (total mass ≥3kg), and resist high-frequency vibrations (originating from alternating magnetic fields). However, traditional screw-locking or snap-fit structures are prone to loosening under cyclic thermal stress, which can easily lead to resonance noise and uneven heating. In addition, the assembly tolerance between the radiation shielding plate 2 and the base 1 further weakens the overall rigidity, resulting in a decrease in the edge magnetic field shielding effectiveness. Current solutions to these problems mostly rely on increasing material thickness or reinforcing screws, but this contradicts the trend of miniaturization and low cost in equipment. Therefore, this application provides an assembly structure for assembling a base 1 and a radiation shielding plate 2, so as to make the assembly of the base 1 and the radiation shielding plate 2 more stable and avoid the problem of resonance noise and decreased magnetic shielding effectiveness caused by the base 1 and the radiation shielding plate 2 becoming loose.
[0041] The assembly structure includes a base 1 and a radiation shielding plate 2. One function of the base 1 is to support and isolate the radiation shielding plate 2 from external contact. The radiation shielding plate 2 absorbs or reflects the leaked magnetic field through a high-permeability magnetic material (such as silicon steel sheet or ferrite), reducing the radiation intensity to within a safe threshold, thereby playing a role in magnetic shielding. At the same time, the radiation shielding plate 2 forms a physical barrier between the electromagnetic coil and the base 1, blocking the outward diffusion path of the magnetic field, thus playing a role in structural isolation. Furthermore, the radiation shielding plate 2 serves as a heat dissipation layer, preventing high temperatures from affecting the lifespan of the base 1, thereby playing a role in thermal protection.
[0042] The radiation shielding plate 2 is mounted on the top of the base 1, that is, the radiation shielding plate 2 is located inside the base 1, so as to better perform magnetic shielding, structural isolation, thermal protection and other functions. It can also protect the radiation shielding plate 2 from external objects coming into contact with the radiation shielding plate 2, thus avoiding safety hazards.
[0043] To ensure a more stable assembly connection between the base 1 and the radiation shielding plate 2, the base 1 is provided with at least two first slots 11, which are spaced apart to ensure the stability of the connection between the base 1 and the radiation shielding plate 2. The first slots 11 extend through the top and bottom of the base 1. The radiation shielding plate 2 is located at the top of the base 1, and the radiation shielding plate 2 is provided with first buckles 21. The number of first buckles 21 is consistent with the number of first slots 11. At the same time, the first buckles 21 extend towards the first slots 11, that is, the first buckles 21 extend from the end fixedly connected to the radiation shielding plate 2 towards the first slots 11. The first buckles 21 and the first slots 11 are arranged in a one-to-one correspondence so that the first buckles 21 and the first slots 11 can be engaged.
[0044] When assembling the base 1 and the radiation shield 2, place the radiation shield 2 at the top of the base 1, align the first buckle 21 with the first slot 11, and pass one end of the first buckle 21 through the first slot 11 from top to bottom, so that one end of the first buckle 21 passes through the first slot 11 from the top of the base 1 and is located at the bottom of the base 1; finally, bend one end of the first buckle 21 along the outer surface of the bottom of the base 1, so that one end of the first buckle 21 is pressed against the outer side of the bottom of the base 1, so that one end of the first buckle 21 and the base 1 are tightly fitted, thus completing the assembly of the assembly structure.
[0045] This application provides a first slot 11 on the base 1 and a first buckle 21 on the radiation shielding plate 2. By passing one end of the first buckle 21 from top to bottom through the first slot 11 and bending and pressing it onto the outer side of the bottom end of the base 1, the assembly constraint force is enhanced, making the base and the radiation shielding plate form a rigid connection. This improves the fixation of the assembly of the first buckle 21 and the first slot 11, thereby improving the firmness of the assembly of the base 1 and the radiation shielding plate 2, avoiding the phenomenon of loosening of the base 1 and the radiation shielding plate 2, solving the resonance and abnormal noise problem caused by the loose assembly of the base 1 and the radiation shielding plate 2, improving the user experience, and making the assembly process more convenient.
[0046] In a specific embodiment, refer to Figures 1 to 12As shown, the first buckle 21 is spaced apart along the circumference of the radiation shielding plate 2 on the outer edge of the radiation shielding plate 2. Specifically, to further improve the engagement strength of the first buckle 21 and the first slot 11, multiple first buckles 21 are provided on the outer edge of the radiation shielding plate 2, and multiple first buckles 21 are spaced apart along the circumference of the radiation shielding plate 2, so as to assemble and fix the radiation shielding plate 2 to the base 1 on the outer side, so that the radiation shielding plate 2 can be stably fixed to the top of the base 1, avoiding the phenomenon of unstable fixation on the outer edge of the radiation shielding plate 2, and further improving the firmness of the assembly of the radiation shielding plate 2 and the base 1.
[0047] More specifically, since rice cookers are generally circular, in order to fit the shape of the rice cooker and the structure of the inner pot, the radiation shielding plate 2 is mostly set as a double-ring structure to minimize magnetic field leakage and maximize structural stability within a limited space. Therefore, the first buckle 21 is set on the outer edge of the radiation shielding plate 2 to fix the radiation shielding plate 2 to the greatest extent and prevent the outer edge of the radiation shielding plate 2 from becoming unstable under vibration.
[0048] In one embodiment, reference is made to Figures 11 to 12 As shown, the inner edge of the radiation shielding plate 2 is also provided with a plurality of second buckles 22 at intervals, and the base 1 is also provided with a plurality of second slots 12, the second slots 12 passing through the top and bottom of the base 1; during assembly, the second buckles 22 pass through the second slots 12 from top to bottom and are bent and pressed against the outer side of the bottom end of the base 1. Specifically, most of the radiation shielding plates 2 are hollow structures, i.e., the radiation shielding plates 2 are double-ring structures. Considering that the material of the radiation shielding plates 2 is relatively soft, when the first buckle 21 is pressed, the radiation shielding plates 2 are subject to unbalanced forces, which can easily damage the radiation shielding plates 2. Therefore, in this embodiment, a plurality of second buckles 22 are provided on the inner edge of the radiation shielding plates 2. The plurality of second buckles 22 are spaced apart along the circumference of the radiation shielding plates 2. Furthermore, a plurality of second slots 12 are provided on the base 1. The number of second slots 12 and second buckles 22 is the same, and the second slots 12 and second buckles 22 are correspondingly arranged. The second slots 12 penetrate the top and bottom of the base 1. At the same time, the second buckles 22 extend toward the direction of the second slots 12, i.e., the second buckles 22 extend from the end that is fixedly connected to the radiation shielding plates 2 toward the direction of the second slots 12, so that the second buckles 22 can cooperate with the second slots 12 for fixation.
[0049] When assembling the base 1 and the radiation shielding plate 2, place the radiation shielding plate 2 at the top of the base 1, align the first buckle 21 with the first slot 11, align the second buckle 22 with the second slot 12, pass one end of the first buckle 21 through the first slot 11 from top to bottom, and pass one end of the second buckle 22 through the second slot 12 from top to bottom, so that one end of the first buckle 21 and one end of the second buckle 22 pass through the first slot 11 and the second slot 12 respectively from the top of the base 1 and are located at the bottom of the base 1; finally, bend one end of the first buckle 21 and one end of the second buckle 22 along the outer surface of the bottom of the base 1, so that one end of the first buckle 21 and one end of the second buckle 22 are pressed against the outer side of the bottom of the base 1, so that one end of the first buckle 21 and one end of the second buckle 22 are tightly fitted to the base 1, thus completing the assembly of the assembly structure.
[0050] Therefore, the outer and inner edges of the radiation shielding plate 2 are assembled and fixed to the base 1 by the first buckle 21 and the second buckle 22, so as to further improve the firmness of the assembly of the radiation shielding plate 2 and the base 1, ensure that the outer and inner sides of the radiation shielding plate 2 can be subjected to balanced force, and improve the service life.
[0051] In a specific embodiment, refer to Figures 13 to 14 As shown, multiple first buckles 21 are spaced apart along the circumference of the radiation shielding plate 2 in the central region 23 of the radiation shielding plate 2. Specifically, most of the radiation shielding plate 2 is a hollow structure, that is, the radiation shielding plate 2 is a double-ring structure. Considering that the material of the radiation shielding plate 2 is relatively soft and easily damaged during pressing, the first buckles 21 are located in the central region 23 of the radiation shielding plate 2, and multiple first buckles 21 are spaced apart along the circumference of the radiation shielding plate 2, that is, the first buckles 21 are located between the outer edge and the inner edge of the radiation shielding plate 2. This makes the fixed position of the radiation shielding plate 2 and the base 1 in the central position of the radiation shielding plate 2. During pressing, the force on the radiation shielding plate 2 can be evenly distributed, improving its service life and the assembly firmness of the radiation shielding plate 2 and the base 1.
[0052] In one embodiment, reference is made to Figure 6As shown, the first buckle 21 has an indentation 211, which extends along the width direction of the first buckle 21 to allow the first buckle 21 to be bent along the indentation 211 during assembly. Specifically, after one end of the first buckle 21 passes through the first slot 11 from top to bottom and is located at the bottom end of the base 1, the first buckle 21 needs to be bent and pressed against the outer surface of the bottom end of the base 1 to improve the firmness of the assembly of the first buckle 21 and the first slot 11. To facilitate pressing one end of the first buckle 21, an indentation 211 is provided on the first buckle 21. The indentation 211 extends along the width direction of the first buckle 21 and has a certain inclination angle. Therefore, when assembling the radiation shielding plate... When assembling the radiation shielding plate 2 and the base 1, the first buckle 21 is passed through the first slot 11 from top to bottom, and then one end of the first buckle 21 is bent along the indentation 211 so that one end of the first buckle 21 is accurately bent and fully pressed with the base 1, improving the accuracy and efficiency of the pressing process. At the same time, during the assembly process of the radiation shielding plate 2 and the base 1, the first buckle 21 and the base 1 are tightly fitted, improving the fit between the first buckle 21 and the base 1, thereby improving the assembly and fixing strength of the radiation shielding plate 2 and the base 1.
[0053] More specifically, the first buckle 21 is an upwardly protruding L-shaped structure, which makes it easier for the user to insert the first buckle 21 into the first slot 11 and bend and press it to improve assembly efficiency.
[0054] More specifically, the second buckle 22 is also provided with an indentation 211 along its width direction. After the second buckle 22 passes through the second slot 12 from top to bottom, one end of the second buckle 22 is bent along the indentation 211 of the second buckle 22 and one end of the second buckle 22 is pressed against the outer surface of the base 1 to improve the pressing accuracy and pressing efficiency.
[0055] More specifically, the first buckle 21 and the second buckle 22 of the radiation shielding plate 2 can be pressed together manually or with a special tool. To ensure product consistency, pressing with a tool results in better quality.
[0056] In a specific embodiment, refer to Figure 4As shown, a limiting rib 111 is provided in the first slot 11 along its width direction to limit the circumferential position of the first buckle 21. Specifically, the first slot 11 is also provided with a limiting rib 111, which extends along the width direction of the first slot 11. The limiting rib 111 is used to limit the circumferential position of the first buckle 21 so that after the first buckle 21 passes through the first slot 11, it can be limited within a limited range of the limiting rib 111 and the first slot 11. This further avoids the first buckle 21 having too large a gap in the first slot 11, which could cause it to wobble. This ensures the accuracy and fixation of the first buckle 21 during bending and pressing, improves the tightness and firmness of the fit between the first buckle 21 and the outer side of the bottom of the base 1, and ultimately avoids the resonance noise problem caused by the loosening of the radiation shield 2 and the base 1, thus improving the user experience.
[0057] More specifically, there are two limiting ribs 111, which are respectively located on opposite sides of the first slot 11, so that after the first buckle 21 passes through the first slot 11, both sides of the first buckle 21 are limited by the limiting ribs 111, thereby improving the stability of the fixation of the first buckle 21 and the first slot 11 and improving the structural strength of the assembly structure.
[0058] In one embodiment, reference is made to Figure 5 and Figure 8 , Figure 10As shown, the base 1 has a protrusion 13 that protrudes upward from the bottom end of the base 1, and the first slot 11 is located on the protrusion 13 and extends through both ends of the protrusion 13. Specifically, the base 1 has a protrusion 13 that protrudes upward from the bottom end of the base 1, and the protrusion 13 protrudes outward from the top end of the base 1. Viewed from below the bottom end of the base 1, the protrusion 13 is recessed. The first slot 11 is located on the protrusion 13 and extends through the top and bottom ends of the protrusion 13. Therefore, the first slot 11 is located in the recessed position at the bottom end of the base 1, that is, the first slot 11 is located inside the bottom end of the base 1, avoiding direct contact between the first slot 11 and the outside. The base 1 has an upwardly protruding opening structure for the first slot 11. The opening mechanism is the first slot 11. When one end of the first buckle 21 passes through the first slot 11 from the top of the base 1 and is located at the bottom of the base 1, and then the first end of the first buckle 21 is bent and pressed against the outer side of the bottom of the base 1, the first end of the first buckle 21 is located in the recessed position of the base 1. Therefore, the first buckle 21 is at a certain distance from the bottom of the base 1, which avoids the first buckle 21 being directly exposed to the outside, causing safety hazards, and at the same time protects the first buckle 21 and improves its service life.
[0059] More specifically, the protrusion height of the protrusion 13 is designed to be 4mm, that is, the distance between the top of the protrusion 13 and the upper surface of the base 1 is 4mm. This avoids the radiation shielding plate 2 being completely pressed against the top of the base 1, thus preventing damage to the base 1 and wear on both of them due to the base 1 being made of plastic material. The radiation shielding plate 2 and the base 1 do not interfere with each other, thereby improving the service life of the base 1 and the radiation shielding plate 2.
[0060] In a specific embodiment, refer to Figure 10As shown, the distance H from one end of the first buckle 21 to the bottom end of the base 1 satisfies the relationship 2mm≤H≤10mm. Specifically, after one end of the first buckle 21 passes through the first slot 11 and is bent and pressed into the recessed position at the bottom end of the base 1, in order to ensure the safety of the base 1 and the radiation shielding plate 2 and avoid the radiation shielding plate 2 being exposed and causing safety hazards, the distance H from one end of the first buckle 21 to the bottom end of the base 1 satisfies the relationship 2mm≤H≤10mm. That is, the distance H between the outer surface of one end of the first buckle 21 and the outermost outer surface of the bottom end of the base 1 must satisfy 2mm≤H≤10mm, thereby improving the safety of the base 1 and the radiation shielding plate 2, preventing the radiation shielding plate 2 from contacting the outside world, and at the same time, ensuring the structural strength of the base 1.
[0061] More specifically, in this embodiment, the distance H from one end of the first buckle 21 to the bottom end of the base 1 is designed to be 4.1mm, so as to ensure safety while saving costs.
[0062] In one embodiment, reference is made to Figure 5 As shown, the base 1 is also provided with a plurality of supporting ribs 14, which are spaced apart and protrude upward from the top of the base 1 to raise the radiation shield 2. Specifically, to further ensure the safety of the base 1 and the radiation shielding plate 2, a plurality of supporting ribs 14 are provided on the base 1. The plurality of supporting ribs 14 are spaced apart and evenly arranged at the top of the base 1. The supporting ribs 14 protrude upward from the top of the base 1. Therefore, when assembling the radiation shielding plate 2 and the base 1, when the radiation shielding plate 2 is placed at the top of the base 1, the supporting ribs 14 are located between the bottom of the base 1 and the radiation shielding plate 2. The supporting ribs 14 are used to raise the radiation shielding plate 2, thereby ensuring that after the radiation shielding plate 2 is assembled, the first buckle 21 can meet the safety requirements and is not easily touched by human hands, thus improving safety. The supporting ribs 14 can ensure that the radiation shielding plate 2 is evenly stressed and that the radiation shielding plate 2 is not directly pressed against the base 1, thereby improving the lifespan of the radiation shielding plate 2 and the base 1.
[0063] This application also provides a rice cooker (not shown in the figure), which includes an assembly structure. The assembly structure is any of the assembly structures described above. Since the assembly structure has been described in detail in the above embodiments, it will not be repeated here.
[0064] The rice cooker described in this application, due to the adoption of the assembly structure, is easy to assemble and the base 1 and the anti-radiation plate 2 are firmly assembled, preventing the base 1 and the anti-radiation plate 2 from becoming loose. Therefore, it reduces the problem of abnormal noise when the user uses the rice cooker and improves the user experience.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
