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. Utility Model Content

[0028] 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.
[0029] Reference Figures 1 to 5 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 top of the base 1 is provided with a plurality of upwardly protruding mounting blocks 11, and each mounting block 11 is provided with through holes 111 extending through its left and right sides. The radiation shielding plate 2 is located at the top of the base 1, and the radiation shielding plate 2 is provided with a plurality of horizontally extending buckles 21. During assembly, one end of each buckle 21 is horizontally rotated through the through hole 111 and bent and pressed against the top of the mounting block 11.
[0030] 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 buckle 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. 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.
[0031] 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.
[0032] 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.
[0033] To ensure a more secure assembly connection between the base 1 and the radiation shielding plate 2, multiple mounting blocks 11 are provided at the top of the base 1. These mounting blocks 11 are used to assemble and fix the radiation shielding plate 2. The mounting blocks 11 protrude upwards from the top of the base 1, and are spaced apart circumferentially along the base 1 to improve the uniformity of the assembly position between the mounting blocks 11 and the radiation shielding plate 2. Furthermore, each mounting block 11 is provided with a through hole 111, which horizontally extends through both the left and right sides of the mounting block 11. Therefore, the through hole 111 is located above the base 1, and its extending direction is parallel to... The horizontal planes of the base 1 are horizontal to each other; the radiation shielding plate 2 is assembled at the top of the base 1, that is, the radiation shielding plate 2 is located inside the base 1, thereby ensuring that the radiation shielding plate 2 does not come into contact with the outside world and avoids safety hazards; the radiation shielding plate 2 is provided with a plurality of buckles 21, the number of buckles 21 is the same as that of the mounting blocks 11, and the buckles 21 and the mounting blocks 11 are correspondingly arranged, the buckles 21 are horizontally extended, and the buckles 21 and the main body of the radiation shielding plate 2 are parallel, so that the extension direction of the buckles 21 is consistent with that of the through hole 111, so as to facilitate the assembly and fixation of the buckles 21 and the through hole 111.
[0034] When assembling the base 1 and the radiation shielding plate 2, place the radiation shielding plate 2 on the top of the base 1, align the buckle 21 with the through hole 111, and rotate one end of the buckle 21 horizontally so that one end of the buckle 21 passes through the through hole 111 from one side and is located on the other side of the through hole 111, thereby making the radiation shielding plate 2 snap onto the mounting block 11; finally, bend the bottom outer surface of the buckle 21 located on the other side of the through hole 111 along the reverse bend of the top outer surface of the mounting block 11, that is, bend the buckle 21 located on the other side of the through hole 111 upward and towards one side of the through hole 111, so that one end of the buckle 21 presses against the outer surface of the top of the mounting block 11, so that one end of the buckle 21 and the mounting block 11 fit tightly together, completing the assembly of the assembly structure.
[0035] This application improves the fit and fixation of the buckles 21 and the mounting blocks 11 by providing multiple mounting blocks 11 at the top of the base 1, with each mounting block 11 having a horizontal through hole 111 extending through its left and right sides. The radiation shielding plate 2 has multiple horizontally extending buckles 21. By horizontally rotating one end of each buckle 21 through the through hole 111 and then bending and pressing it onto the outer surface of the top of the mounting block 11, the assembly constraint of the buckles 21 and the mounting blocks 11 is enhanced, making the base 1 and the radiation shielding plate 2 form a rigid connection. This improves the assembly and fixation of the buckles 21 and the mounting blocks 11, thereby increasing the firmness of the assembly of the base 1 and the radiation shielding plate 2, preventing loosening of the base 1 and the radiation shielding plate 2, solving the resonance and noise problem caused by loose assembly of the base 1 and the radiation shielding plate 2, improving the magnetic shielding effectiveness of the radiation shielding plate 2, enhancing the user experience, and making assembly more convenient.
[0036] In a specific embodiment, refer to Figures 1 to 4 As shown, multiple buckles 21 are spaced apart along the circumference of the radiation shielding plate 2 in the central region 22 of the radiation shielding plate 2. Specifically, since rice cookers are generally circular, to fit the shape of the rice cooker and the structure of the inner pot, the radiation shielding plate 2 is mostly designed as a double-ring structure, that is, the radiation shielding plate 2 is a hollow structure, in order to minimize magnetic field leakage and maximize structural stability within a limited space; at the same time, considering that the material of the radiation shielding plate 2 is relatively soft, the radiation shielding plate 2 may be easily damaged due to uneven force when bending and pressing the buckles 21. Therefore, the buckles 21 are located in the central region 22 of the radiation shielding plate 2. The central region 22 refers to the area between the outer edge and the inner edge of the radiation shielding plate 2, and multiple buckles 21 are spaced apart along the circumference of the radiation shielding plate 2. The buckle 21 is positioned between the outer and inner edges of the radiation shielding plate 2, so that the assembly position of the radiation shielding plate 2 and the base 1 is in the middle of the radiation shielding plate 2. When the buckle 21 is bent and pressed, the radiation shielding plate 2 can be subjected to uniform force, avoiding damage to the radiation shielding plate 2 and improving the service life of the radiation shielding plate 2. Furthermore, since the assembly position of the radiation shielding plate 2 and the mounting block 11 is in the middle region 22 of the radiation shielding plate 2, the uniformity of the layout of the assembly position of the radiation shielding plate 2 and the mounting block 11 on the radiation shielding plate 2 is improved, thereby improving the assembly strength of the radiation shielding plate 2 and the base 1.
[0037] In a more specific embodiment, the radiation shielding plate 2 is provided with three buckles 21, which are spaced apart in the central region 22. The base 1 is provided with three mounting blocks 11, which are respectively engaged and fixed to the three buckles 21. Specifically, since part of the radiation shielding plate 2 is circular, this embodiment provides three buckles 21. The three buckles 21 are evenly and spaced apart along the circumference of the radiation shielding plate 2 in the central region 22. At the positions corresponding to the three buckles 21, the base 1 is also provided with three mounting blocks 11, so that the three mounting blocks 11 and the three buckles 21 are respectively engaged and fixed to fix the radiation shielding plate 2 and the base 1 from all sides. This ensures the assembly strength of the radiation shielding plate 2 and the base 1 while reducing production costs.
[0038] In one embodiment, reference is made to Figures 1 to 4 As shown, the radiation shielding plate 2 is also provided with multiple clearance holes 23. These clearance holes 23 are adjacent to the buckle 21 and are used to avoid the mounting block 11. Specifically, because the radiation shielding plate 2 is assembled from above the base 1 into the interior of the base 1, and to allow the buckle 21 to quickly and easily rotate horizontally into the through hole 111, multiple clearance holes 23 are provided on the radiation shielding plate 2. These clearance holes 23 are used to avoid the mounting block 11, allowing the radiation shielding plate 2 to pass through the mounting block 11 and be assembled onto the top of the base 1, thus improving the assembly efficiency of the radiation shielding plate 2. The clearance holes 23 are adjacent to the buckle 21, so that when the radiation shielding plate 2 is assembled onto the base 1, the mounting block 11 passes through the clearance holes 23. The buckle 21 is adjacent to the mounting block 11, and the buckle 21 and the through hole 111 are aligned. The buckle 21 should be positioned on one side of the through hole 111. The radiation shielding plate 2 should then be rotated horizontally so that one end of the buckle 21 rotates toward the through hole 111. One end of the buckle 21 passes through the through hole 111 and is located on the other side of the through hole 111. Then, one end of the buckle 21 is bent in the opposite direction along the top of the mounting block 11 to press against the outer surface of the top of the mounting block 11. This ultimately increases the constraint force of the buckle 21 and the mounting block 11, improves the firmness of the assembly of the buckle 21 and the mounting block 11, and allows the base 1 and the radiation shielding plate 2 to be fixedly connected, avoiding the phenomenon of the radiation shielding plate 2 becoming loose, which could cause resonance and abnormal noise, and improving the user experience.
[0039] More specifically, the length and width of the clearance hole 23 are greater than the length and width of the mounting block 11, that is, the overall size of the clearance hole 23 is greater than the size of the mounting block 11, so that the mounting block 11 can pass through the clearance hole 23, improve installation efficiency, avoid interference between the radiation shielding plate 2 and the mounting block 11, and improve the service life of the radiation shielding plate 2.
[0040] In a specific embodiment, refer to Figure 4 As shown, one end of the buckle 21 extends horizontally from one side of the clearance hole 23 toward the other side of the clearance hole 23. Specifically, the buckle 21 is arranged adjacent to the clearance hole 23, with the buckle 21 located on one side of the clearance hole 23, and one end of the buckle 21 extending horizontally from one side of the clearance hole 23 toward the other side of the clearance hole 23, so that one end of the buckle 21 extends into the interior of the clearance hole 23. Therefore, the length and width of one end of the buckle 21 are both smaller than the length and width of the clearance hole 23, making one end of the buckle 21 movable inside the clearance hole 23. When the radiation shielding plate 2 and the base 1 are assembled, the clearance hole 23 passes through the mounting block 11. At this time, both the mounting block 11 and one end of the buckle 21 are located inside the clearance hole 23, and one end of the buckle 21 is located on one side of the mounting block 11. Furthermore, the buckle 21 is correspondingly provided with the through hole 111. The buckle 21 is located on one side of the through hole 111. Then, the radiation shielding plate 2 is rotated horizontally so that one end of the buckle 21 rotates towards the through hole 111. One end of the buckle 21 passes through the through hole 111 and is located on the other side of the through hole 111. Then, one end of the buckle 21 is bent in the opposite direction along the top of the mounting block 11 to press against the outer surface of the top of the mounting block 11. This ultimately improves the constraint force of the assembly between the buckle 21 and the mounting block 11, and improves the firmness of the assembly between the buckle 21 and the mounting block 11. This allows the base 1 and the radiation shielding plate 2 to be fixedly connected, avoiding the phenomenon of the radiation shielding plate 2 becoming loose, thus preventing resonance and abnormal noise, and improving the user experience.
[0041] Therefore, in this embodiment, by extending one end of the buckle 21 horizontally into the interior of the clearance hole 23, the assembly of one end of the buckle 21 with the mounting block 11 is ensured, thereby improving the smoothness of assembly and increasing assembly efficiency.
[0042] More specifically, the buckle 21 and the main body of the radiation shielding plate 2 are an integral structure. Therefore, after the clearance hole 23 is provided on the main body of the radiation shielding plate 2, the main body part on one side of the clearance hole 23 extends horizontally to the other side of the clearance hole 23 to extend the buckle 21, so as to improve the structural strength of the radiation shielding plate 2 and reduce the production cost.
[0043] In one embodiment, reference is made to Figure 4 As shown, the buckle 21 has an indentation 211, which extends along the width of the buckle 21 so that the buckle 21 can be bent along the indentation 211 during assembly. Specifically, after the radiation shielding plate 2 is assembled to the top of the base 1, one end of the buckle 21 needs to be rotated horizontally so that one end of the buckle 21 passes through the through hole 111 from one side and is located on the other side of the through hole 111, thereby making the radiation shielding plate 2 snap onto the mounting block 11; then, the end of the buckle 21 located on the other side of the through hole 111 needs to be bent along the outer surface of the bottom end of the top outer surface of the mounting block 11, that is, the end of the buckle 21 located on the other side of the through hole 111 is bent upward and towards one side of the through hole 111, so that one end of the buckle 21 is pressed against the outer surface of the top of the mounting block 11, thereby improving the firmness of the assembly of the buckle 21 and the mounting block 11. One end of the buckle 21 has an indentation 211. The indentation 211 extends along the width of the buckle 21 and has a certain inclination angle. Therefore, when assembling the radiation shielding plate 2 and the base 1, the buckle 21 is rotated horizontally through the through hole 111, and then one end of the buckle 21 is bent along the indentation 211. This allows the one end of the buckle 21 to be accurately bent and fully pressed against the mounting block 11, improving the accuracy and efficiency of the pressing process. At the same time, during the assembly of the radiation shielding plate 2 and the base 1, the outer surfaces of the top of the buckle 21 and the mounting block 11 are tightly fitted, improving the fit between the buckle 21 and the mounting block 11, thereby increasing the assembly and fixing strength of the radiation shielding plate 2 and the base 1.
[0044] More specifically, the buckles 21 of the radiation shielding plate 2 can be pressed by hand or by a special tool. To ensure product consistency, pressing with a tool results in better quality.
[0045] In a specific embodiment, refer to Figure 5As shown, a first support rib 112 is provided on one side of the mounting block 11. The top end of the first support rib 112 is lower than the top end of the mounting block 11, and the top end of the first support rib 112 abuts against the bottom end of the radiation shielding plate 2. Specifically, a first supporting rib 112 is also provided on the mounting block 11. The first supporting rib 112 is used to support the radiation shielding plate 2. Therefore, the first supporting rib 112 is set on one side of the mounting block 11, that is, the first supporting rib 112 is located on one side of the through hole 111. The side of the through hole 111 refers to the side of the through hole 111 that is close to the buckle 21 in the initial state. The top of the first supporting rib 112 is lower than the top of the mounting block 11, that is, the top of the first supporting rib 112 is lower than the upper end of the through hole 111, so as to ensure that the buckle 21 can pass smoothly through the through hole 111 to realize the assembly operation. Thus, when the radiation shielding plate 2 is assembled onto the base 1, the radiation shielding plate 2 can overlap the first supporting rib 112 in advance. On the supporting rib 112, when the radiation shielding plate 2 is rotated horizontally, the first supporting rib 112 can continuously support the radiation shielding plate 2, improving stability during rotation and ensuring that the buckle 21 can pass horizontally through the through hole 111, improving the accuracy and efficiency of assembly; and when bending and pressing the buckle 21, the first supporting rib 112 can also increase the stress strength of the radiation shielding plate 2, preventing the radiation shielding plate 2 from being damaged; at the same time, the first supporting rib 112 can raise the radiation shielding plate 2, thereby ensuring that the radiation shielding plate 2 and the base 1 are not tightly fitted after assembly, meeting safety requirements, improving safety, and also improving the heat dissipation efficiency of the radiation shielding plate 2, avoiding damage to the base 1, and thus increasing the service life of the base 1.
[0046] In one embodiment, reference is made to Figure 5As shown, there are two first support ribs 112, and the two first support ribs 112 are respectively located on both sides of the through hole 111, and are arranged on one side of the mounting block 11 along the extension direction of the through hole 111. Specifically, the first support ribs 112 are used to support the radiation shielding plate 2. When the radiation shielding plate 2 has not yet rotated horizontally, the radiation shielding plate 2 first overlaps the first support ribs 112 to ensure that the radiation shielding plate 2 can maintain a horizontal rotation in subsequent operations, improving installation efficiency and accuracy. There are two first support ribs 112, and the two first support ribs 112 are respectively located on both sides of the through hole 111, that is, the two first support ribs 112 are respectively corresponding to the two sides of the through hole 111, so that the two first support ribs 112 can stably support the radiation shielding plate 111. The radiation shielding plate 2 is designed to prevent it from shaking or swaying. Simultaneously, since the radiation shielding plate 2 has a clearance hole 23, after the mounting block 11 passes through the clearance hole 23, the other side of the mounting block 11 is within the range of the clearance hole 23. At this time, the radiation shielding plate 2 is in a hollow state. Therefore, the first support rib 112 extends along the extension direction of the through hole 111 and is disposed on one side of the mounting block 11, so that the first support rib 112 more stably supports the radiation shielding plate 2 and improves the stability and smoothness of the rotation of the radiation shielding plate 2 on the first support rib 112.
[0047] More specifically, the height of the first support rib 112 is 4mm. In this embodiment, the height of the first support rib 112 is set to 4mm, that is, the height of the first support rib 112 protruding upward from the top of the base 1 is 4mm. This ensures the safety and heat dissipation between the radiation shielding plate 2 and the base 1 while also saving costs.
[0048] In one embodiment, reference is made to Figure 5As shown, the base 1 is also provided with a plurality of second support ribs 12, 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 second support ribs 12 are provided on the base 1. The plurality of second support ribs 12 are spaced apart and evenly arranged at the top of the base 1. The second support ribs 12 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 second support ribs 12 are located between the top of the base 1 and the radiation shielding plate 2. The second support ribs 12 are used to raise the radiation shielding plate 2, thereby ensuring that after the radiation shielding plate 2 is assembled, it can cooperate with the first support ribs 112 to raise and support the radiation shielding plate 2, making the support points of the radiation shielding plate 2 more uniform, thereby improving the stability of the radiation shielding plate 2 and its smoothness in rotation. At the same time, it can also improve the structural stability of the assembly structure and increase the service life of the base 1 and the radiation shielding plate 2.
[0049] 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.
[0050] 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.
