Description

Technical Field

[0001] This utility model relates to the field of rice cooker technology, and in particular to an anti-radiation installation component and a rice cooker. Background Technology

[0002] IH (Induction Heating) rice cookers, also known as electromagnetic induction heating rice cookers, occupy an important position in the kitchen appliance market due to their high heating efficiency and even heating. The working principle of an IH rice cooker is based on electromagnetic induction. A high-frequency alternating magnetic field is generated through a winding coil, causing the inner pot of the rice cooker to heat up, thus achieving a rapid and even heating effect.

[0003] In the structural design of IH rice cookers, the anti-radiation plate is a key component. Because the high-frequency alternating magnetic field generated by the winding coil produces a certain amount of electromagnetic radiation, in order to reduce the impact of this radiation on the surrounding environment and human health, while ensuring the normal operation of the electronic components inside the rice cooker, an anti-radiation plate is usually installed on the base of the rice cooker to effectively shield and reflect electromagnetic radiation.

[0004] Currently, existing IH rice cookers typically use a flexible snap-fit ​​structure to secure the radiation shielding plate to the base. Specifically, a unique flexible snap-fit ​​structure is designed on the base, and the radiation shielding plate is connected to this structure. The elastic deformation and rebound of the snap-fit ​​ensure a fixed connection between the radiation shielding plate and the base. This connection method offers advantages such as ease of installation and lower cost, and was widely used in the early production and application of IH rice cookers.

[0005] However, in the actual production process of IH rice cookers, extensive practical testing and feedback revealed a significant problem with the aforementioned connection method based on elastic snap-fit ​​structures: the radiation shielding plate is prone to loosening between itself and the base. This is because certain tolerances are unavoidable during the rice cooker's manufacturing process. Furthermore, the elasticity of the snap-fit ​​structure itself may change over long-term use or under external force, weakening its securing effect on the radiation shielding plate. More seriously, when the radiation shielding plate becomes loose, it becomes unstable under the influence of the high-frequency alternating magnetic field generated by the winding coil. This high-frequency alternating magnetic field subjectes the radiation shielding plate to periodic electromagnetic forces, and the loose plate, lacking sufficient restraint, is prone to resonance under this electromagnetic excitation. This resonance not only causes collisions between the radiation shielding plate and the base or other components, producing noticeable abnormal noises and affecting the user experience, but also, with prolonged resonance, can damage the radiation shielding plate itself and the overall structure of the rice cooker, reducing its lifespan and reliability.

[0006] Therefore, in order to solve the problem of loose connection between the radiation shield and the base in existing IH rice cookers, which leads to resonance and abnormal noise, it is necessary to improve the existing connection structure. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide an anti-radiation installation component and a rice cooker.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] In a first aspect, this utility model provides a radiation protection installation component, including: a base and a radiation protection plate. The base is provided with a connecting column, and the radiation protection plate is provided with an irregular hole corresponding to the connecting column. At least three deformable claws are provided on the edge of the irregular hole and extending toward the center of the hole. The claws are interference-fitted to the side wall of the connecting column.

[0010] In one specific embodiment, the connecting post extends outward with a positioning rib, which is adapted to the irregular hole.

[0011] In one specific embodiment, the connecting post is further provided with a snap-fit ​​part between adjacent positioning ribs, and the snap-fit ​​part is adapted to the claw.

[0012] In one specific embodiment, a water leakage hole is also provided at the center of the connecting column.

[0013] In one specific embodiment, the base is further provided with a support rib on the outer periphery of the connecting column, and the support rib abuts against the radiation shielding plate.

[0014] In one specific embodiment, there are three irregular holes, and the included angle between adjacent holes along the circumferential direction is 120 degrees.

[0015] In one specific embodiment, the claw is V-shaped.

[0016] In one specific embodiment, the radiation shield is made of a flexible metal plate.

[0017] In one specific embodiment, the thickness of the radiation shielding plate is 0.3mm-1.2mm.

[0018] The advantages of this radiation shielding installation component compared to existing technologies are as follows: A connecting column is provided on the base, and the radiation shielding plate has corresponding irregularly shaped holes. At least three deformable claws extend from the edge of the irregularly shaped holes towards the center. During installation, the irregularly shaped holes of the radiation shielding plate are aligned with the connecting column on the base. The claws deform when pressed by the side wall of the connecting column, and then are tightly engaged with the side wall of the connecting column through an interference fit. This interference fit utilizes the deformation capacity and elastic recovery force of the claws, resulting in a tight and stable connection between the claws and the connecting column. This enhances the connection strength between the radiation shielding plate and the base, effectively preventing loosening caused by various factors, ensuring the stability of the radiation shielding plate during equipment operation, and solving the problem of abnormal noise caused by resonance.

[0019] Secondly, this utility model embodiment provides a rice cooker, including the anti-radiation mounting assembly as described above.

[0020] The advantages of this rice cooker compared to existing technologies are as follows: By setting up an anti-radiation installation component, and by having a connecting post on the base, and an anti-radiation plate with corresponding irregular holes, at least three deformable claws extend from the edge of the irregular holes towards the center. During installation, the irregular holes of the anti-radiation plate are aligned with the connecting post on the base. When the claws are squeezed by the side wall of the connecting post, they deform and are then tightly engaged with the side wall of the connecting post through an interference fit. This interference fit utilizes the deformation capacity and elastic recovery force of the claws, resulting in a tight and stable connection between the claws and the connecting post. This enhances the connection strength between the anti-radiation plate and the base, effectively avoiding loosening problems caused by various factors, ensuring the stability of the anti-radiation plate during the operation of the rice cooker, and solving the problem of abnormal noise caused by resonance.

[0040] See Figures 1 to 8As shown, this utility model discloses a specific embodiment of a radiation protection installation component, including: a base 10 and a radiation protection plate 20. The base 10 is provided with a connecting post 11, and the radiation protection plate 20 is provided with an irregular hole 21 corresponding to the connecting post 11. At least three deformable claws 22 are provided on the edge of the irregular hole 21 and extending towards the center of the hole. The claws 22 are interference-fitted to the side wall of the connecting post 11.

[0041] Specifically, the base 10 is typically made of materials with certain strength and heat resistance, such as plastic or metal, to ensure stable support of the radiation shielding plate 20 and other components during the operation of devices such as IH rice cookers. Connecting posts 11 are precisely designed and machined on the base 10 according to the installation position and layout requirements of the radiation shielding plate 20. The shape of the connecting post 11 can be a regular shape such as cylindrical or rectangular, and its size needs to be determined based on the size of the irregular hole 21 and the required interference fit. For example, if a cylindrical connecting post 11 is used, its diameter will be slightly larger than the diameter of the corresponding jaw 22 mating part in the irregular hole 21 to achieve an interference fit. The radiation shielding plate 20 is also made of materials suitable for shielding electromagnetic radiation, such as composite boards containing special metallic components. Irregular holes 21 are made on the radiation shielding plate 20 at positions corresponding to the connecting posts 11, and the shape and size of the irregular holes 21 must match the connecting posts 11. At least three deformable claws 22 extend from the edge of the irregular hole 21 toward the center of the hole. The shape of the claws 22 can be a sheet-like structure with a certain curvature, and its thickness and width are designed according to the actual assembly requirements and the deformation capacity of the material. The number of claws 22 is generally three or more to ensure that sufficient clamping force can be provided during interference fit to make the radiation shielding plate 20 firmly connected to the base 10.

[0042] In other words, by providing a connecting post 11 on the base 10 and a corresponding irregular hole 21 on the radiation shielding plate 20, with at least three deformable claws 22 extending from the edge of the irregular hole 21 towards the center, during installation, the irregular hole 21 of the radiation shielding plate 20 is aligned with the connecting post 11 of the base 10. When the claws 22 are squeezed by the side wall of the connecting post 11, they deform and are then tightly engaged with the side wall of the connecting post 11 through an interference fit. This interference fit utilizes the deformation capacity and elastic recovery force of the claws 22, so that a tight and stable connection is formed between the claws 22 and the connecting post 11, enhancing the connection strength between the radiation shielding plate 20 and the base 10, effectively avoiding loosening problems caused by various factors, ensuring the stability of the radiation shielding plate 20 during equipment operation, and solving the problem of abnormal noise caused by resonance. Furthermore, the interference fit between the claw 22 and the side wall of the connecting column 11 generates significant friction and clamping force. This tight fit effectively resists various external forces generated during equipment operation, such as vibration and impact, thus preventing loosening between the radiation shield 20 and the base 10. For example, when the IH rice cooker is operating, the high-frequency alternating magnetic field generated by the winding coil will cause some vibration in the equipment. However, due to the firm connection between the claw 22 and the connecting column 11, the radiation shield 20 can always remain in the correct position without displacement. In addition, the design of at least three deformable claws 22 on the edge of the irregular hole 21 increases the stability and reliability of the connection. Multiple claws 22 clamp the connecting column 11 from different directions, distributing the force and avoiding loosening caused by the failure of a single claw 22. Even if one claw 22 is accidentally damaged or deformed, the other claws 22 can still continue to play a fixing role, ensuring the stability of the connection between the radiation shield 20 and the base 10. Furthermore, because the radiation shielding plate 20 is firmly connected to the base 10, it will not easily vibrate due to the electromagnetic force of the high-frequency alternating magnetic field during equipment operation. Even if minor vibrations occur, they will be suppressed by the tight fit between the claw 22 and the connecting column 11, reducing the transmission of vibration to the base 10 and other components. This avoids resonance noise caused by the vibration of the radiation shielding plate 20 colliding with the base 10 or other components, providing a quiet operating environment for the user.

[0043] See Figures 1 to 6 As shown, in one embodiment, the connecting post 11 extends outward with a positioning rib 111, which is adapted to the irregular hole 21.

[0044] Specifically, a positioning rib 111 is designed to extend from the outer side of the connecting post 11. The shape and size of the positioning rib 111 must be adapted to the irregular hole 21. For example, if the irregular hole 21 is a hole with a specific shaped edge, the positioning rib 111 can be designed with a corresponding shape, such as a protrusion with a certain curvature or an edge with a specific angle. Sufficient space is reserved in the irregular hole 21 for the positioning rib 111 to be inserted, while ensuring that the edge of the irregular hole 21 and the positioning rib 111 can achieve zero-gap assembly or very small-gap assembly.

[0045] In other words, the fitting design of the positioning rib 111 and the irregular hole 21, along with zero-gap or very small-gap assembly, provides a precise positioning reference for the installation of the radiation shielding plate 20. During installation, the positioning rib 111 accurately guides the radiation shielding plate 20 to the correct position, avoiding positional deviation of the radiation shielding plate 20 due to installation errors. This precise positioning ensures a stable relative positional relationship between the radiation shielding plate 20 and the base 10, effectively preventing the radiation shielding plate 20 from shaking during use. Furthermore, because there is almost no gap or a very small gap between the positioning rib 111 and the irregular hole 21, the radiation shielding plate 20 will not easily shift when subjected to external forces, such as equipment vibration or impact. This stable installation structure ensures that the radiation shielding plate 20 always remains in the correct position, improving the structural stability of the entire radiation shielding installation assembly. In addition, the tight fit between the positioning rib 111 and the irregular hole 21 reduces the relative movement between the radiation shielding plate 20 and the base 10. During equipment operation, the high-frequency alternating magnetic field generated by the winding reel will cause the equipment to vibrate. However, since the radiation shield 20 is firmly positioned on the base 10, the energy transmitted to the radiation shield 20 by the vibration is greatly reduced. The presence of the positioning rib 111 limits the minute vibrations of the radiation shield 20 and avoids resonance noise caused by vibration.

[0046] See Figures 3 to 4 As shown, in one embodiment, the connecting post 11 is further provided with a latching part 112 between adjacent positioning ribs 111, and the latching part 112 is adapted to the claw 22.

[0047] Specifically, the latching part 112 can be a structure with a certain shape that protrudes outward from the surface of the connecting column 11, such as a semi-circular protrusion, a triangular protrusion, or a trapezoidal protrusion. As the equipment is used for an extended period, the claw 22 may experience fatigue under long-term bending stress, gradually reducing its elasticity and weakening the interference fit between the claw 22 and the side wall of the connecting column 11. At this point, the claw 22 may further bend and deform, becoming caught on the connecting column 11. When the claw 22 is caught on the connecting column 11, the latching part 112 between adjacent positioning ribs 111 on the connecting column 11 will engage with the claw 22. The shape and position design of the latching part 112 ensures that the claw 22 can be reliably latched, forming a second layer of anti-detachment protection to prevent the radiation shield 20 from falling off the base 10.

[0048] In other words, the interference fit between the claw 22 and the side wall of the connecting column 11 forms the first layer of anti-detachment structure, ensuring a secure connection between the radiation shielding plate 20 and the base 10 under normal conditions. The engagement between the latching part 112 and the claw 22 forms the second layer of anti-detachment protection. When the claw 22 experiences weakened interference fit due to long-term fatigue, the latching part 112 promptly activates to prevent the radiation shielding plate 20 from falling off. This dual anti-detachment mechanism significantly improves the reliability and stability of the radiation shielding installation assembly, reducing equipment failures and safety hazards caused by the detachment of the radiation shielding plate 20. During long-term use of the equipment, various factors may cause changes in the performance of the claw 22. The presence of the latching part 112 allows the radiation shielding installation assembly to adapt to these changes brought about by long-term use, extending the product's lifespan and reducing maintenance and replacement costs.

[0049] See Figures 1 to 6 As shown, in one embodiment, the connecting column 11 is also provided with a water leakage hole 113 at its center.

[0050] Specifically, during the rice cooker cooking process, a certain amount of water will be generated inside the rice cooker due to the moisture content of the ingredients and the condensation of steam. This water will flow into the drain hole 113 in the center of the connecting column 11 by gravity, and then be discharged to the outside of the rice cooker along the pre-planned drainage path. For example, during the cooking process, steam condenses on the inner wall of the rice cooker to form water droplets, which will drip onto the base 10 and be discharged through the drain hole 113.

[0051] In other words, rice cookers typically contain various electronic components and circuits. If water accumulates inside, it may seep into these components or circuits, causing electrical safety issues such as short circuits. The drain hole 113 allows water to drain from the rice cooker promptly, keeping the interior dry and effectively reducing the risk of short circuits and electrical leaks caused by water accumulation, thus ensuring user safety. Furthermore, water accumulation can corrode the metal components inside the rice cooker, affecting its performance and lifespan. Timely drainage through the drain hole 113 reduces water corrosion of components, extends the rice cooker's lifespan, and lowers maintenance and replacement costs.

[0052] See Figures 5 to 6 As shown, in one embodiment, the base 10 is further provided with a support rib 12 on the outer periphery of the connecting column 11, and the support rib 12 abuts against the radiation shielding plate 20.

[0053] Specifically, after installation, the radiation shielding plate 20 will be subjected to its own weight, the forces exerted by other components inside the rice cooker, and vibrations and impacts during operation. The support ribs 12 can evenly distribute these forces onto the base 10, preventing the radiation shielding plate 20 from deforming due to excessive stress in localized areas. For example, when the rice cooker vibrates during operation, the support ribs 12 can effectively support the radiation shielding plate 20, preventing it from bending or twisting due to vibration. The support ribs 12 and the connecting column 11 work together to form a stable support structure, improving the strength and rigidity of the entire radiation shielding installation assembly. This stable structure can better withstand various forces inside the rice cooker, ensuring the stability of the radiation shielding plate 20 during operation and reducing malfunctions and safety hazards caused by structural instability. In addition, the flatness of the radiation shielding plate 20 has a significant impact on its radiation shielding performance. If the radiation shielding plate 20 deforms, it may cause uneven gaps between it and other components inside the rice cooker, thereby affecting the shielding effect against electromagnetic radiation. The supporting rib 12 helps maintain the flatness of the radiation shielding plate 20, allowing it to fit tightly against the corresponding position inside the rice cooker, effectively shielding and reflecting electromagnetic radiation, and improving the electromagnetic compatibility of the rice cooker.

[0054] See Figures 7 to 8 As shown, in one embodiment, there are three irregular holes 21, and the included angle between adjacent holes along the circumferential direction is 120 degrees.

[0055] Specifically, since the rotation angle of the entire circumference is 360 degrees, the included angle between any two adjacent irregular holes 21 is 120 degrees. This effectively achieves a uniform distribution of the three irregular holes 21 in the circumferential direction, ensuring that the supporting and fixing forces on the radiation shielding plate 20 are evenly distributed after it is installed on the base 10. During the operation of the rice cooker, regardless of the direction of the force, it can be evenly transmitted to the base 10 through the cooperation of the three connecting columns 11 and the irregular holes 21, avoiding problems such as tilting, shaking, or deformation of the radiation shielding plate 20 due to uneven force distribution, and improving the stability of the installation. In addition, the rice cooker will vibrate during operation, and the evenly distributed irregular holes 21 and connecting column 11 structure can effectively resist this vibration. The three connecting columns 11 provide support for the radiation shielding plate 20 from different directions, enabling it to maintain a relatively stable position during vibration and reducing the risk of loosening and damage caused by vibration.

[0056] In one embodiment, the claw 22 is V-shaped.

[0057] Specifically, the clamp 22 is V-shaped, consisting of two elastic arms of a certain length and thickness. One end of the two elastic arms is connected to form the apex of the V-shape, while the other end is free. The angle between the two elastic arms of the V-shaped clamp 22 is typically between 30 and 90 degrees. If the angle is too small, the clamp 22 may have difficulty passing smoothly through the connecting post 11 during installation; if the angle is too large, the clamping force of the clamp 22 may be insufficient. For example, for common IH rice cookers, the angle can be designed to be around 60 degrees, which ensures both smooth installation and sufficient clamping force.

[0058] In other words, the elastic arm of the V-shaped claw 22 undergoes elastic deformation during installation. After passing through the connecting post 11, it partially recovers its deformation, thereby generating an outward elastic force on the connecting post 11, forming a clamping force. This clamping force effectively fixes the radiation shielding plate 20 to the base 10, preventing it from loosening or falling off due to vibration or external forces during the operation of the rice cooker. For example, during the vibration generated during the heating process of the rice cooker, the elastic clamping force of the V-shaped claw 22 ensures that the radiation shielding plate 20 always maintains a stable position. In addition, because the V-shaped claw 22 has a certain degree of elasticity, it can adapt to the force changes of the rice cooker under different working conditions. When the rice cooker is subjected to a large impact or vibration, the elastic arm of the claw 22 can further deform, absorb some energy, and then return to its original shape, continuing to provide a stable clamping force, thus improving the reliability and stability of the radiation shielding installation component.

[0059] In one embodiment, the radiation shield 20 is made of a flexible metal plate.

[0060] Specifically, commonly used elastic metal plate materials include stainless steel and spring steel. Stainless steel has good corrosion resistance and a certain degree of elasticity. For example, 304 stainless steel has a high yield strength, which can resist the corrosion of environmental factors such as moisture and steam that may exist inside the rice cooker while ensuring a certain degree of elasticity, thus extending the service life of the radiation shielding plate 20. Spring steel has a higher elastic limit and yield strength. For example, 65Mn spring steel can withstand greater deformation without permanent deformation, making it suitable for radiation shielding plates 20 with higher elasticity requirements.

[0061] In other words, the flexible metal plate has good conductivity, effectively shielding and reflecting electromagnetic radiation. When the electronic components inside the rice cooker generate electromagnetic radiation, the anti-radiation plate 20 can reflect this electromagnetic radiation back into the rice cooker, reducing leakage of electromagnetic radiation to the outside and ensuring the safety of the surrounding environment and human body. For example, in an IH rice cooker, the anti-radiation plate 20 made of flexible metal plate can shield high-frequency electromagnetic radiation, reducing interference from electromagnetic radiation to other electronic devices. Furthermore, because the anti-radiation plate 20 is made of flexible metal plate, it can undergo a certain degree of elastic deformation during installation. When the anti-radiation plate 20 is fitted with components such as the connecting column 11, even with certain dimensional deviations or installation errors, the anti-radiation plate 20 can be adjusted through elastic deformation to complete the installation smoothly. For example, when the position of the connecting column 11 is slightly off, the claws 22 and other structures on the anti-radiation plate 20 can adapt to this deviation through elastic deformation, achieving reliable fixation. During the operation of the rice cooker, vibration and impact forces are generated. The anti-radiation plate 20 made of flexible metal plate can act as a shock absorber, absorbing some vibration energy and reducing the impact of vibration on other components inside the rice cooker. At the same time, the elastic deformation also allows the radiation shielding plate 20 to always maintain good contact with the surrounding components, ensuring the stability of the radiation shielding performance.

[0062] In one embodiment, the thickness of the radiation shield 20 is 0.3mm-1.2mm.

[0063] Specifically, the relatively thin thickness (0.3mm-0.6mm), while thin, still provides a certain degree of radiation protection in low-power, small-sized IH rice cookers. Its slim profile minimizes its impact on the overall weight of the rice cooker and reduces material costs. For situations where electromagnetic radiation requirements are not particularly stringent, such as small IH rice cookers used in daily household life, this thickness of radiation shielding plate 20 can meet basic radiation protection needs, preventing excessive impact of electromagnetic radiation on the surrounding environment and human health.

[0064] With a medium thickness (0.6mm-0.9mm), it achieves a good balance between radiation protection performance, cost, and weight. It can effectively shield most electromagnetic radiation and is suitable for most mid-range IH rice cooker products. Its structural stability is relatively good, and it is not easily deformed or damaged during the use of the rice cooker, maintaining stable radiation protection performance over a long period of time.

[0065] With a relatively thick sheet (0.9mm-1.2mm), it offers excellent radiation shielding performance, providing reliable electromagnetic shielding protection for IH rice cookers. It is particularly suitable for high-power, large-size IH rice cookers and applications with extremely high electromagnetic radiation protection requirements, such as professional kitchen equipment or IH rice cookers used in electromagnetically sensitive environments. The thicker sheet also enhances the mechanical strength of the radiation shielding plate 20, improving its durability.

[0066] This utility model also discloses a rice cooker, including the anti-radiation mounting assembly as described above.

[0067] Specifically, by setting up an anti-radiation installation component, and by providing a connecting post 11 on the base 10, and a corresponding irregular hole 21 on the anti-radiation plate 20, with at least three deformable claws 22 extending from the edge of the irregular hole 21 towards the center of the hole, during installation, the irregular hole 21 of the anti-radiation plate 20 is aligned with the connecting post 11 of the base 10. When the claws 22 are squeezed by the side wall of the connecting post 11, they deform and are then tightly engaged with the side wall of the connecting post 11 through an interference fit. This interference fit utilizes the deformation capability and elastic recovery force of the claws 22, so that a tight and stable connection is formed between the claws 22 and the connecting post 11, enhancing the connection strength between the anti-radiation plate 20 and the base 10, effectively avoiding loosening problems caused by various factors, ensuring the stability of the anti-radiation plate 20 during the operation of the rice cooker, and solving the problem of abnormal noise caused by resonance.

[0068] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
