[0002] A rice cooker is a cooking utensil that converts electrical energy into heat energy and is an indispensable electrical appliance in the kitchen. Classified by the heating method, rice cookers can be divided into ordinary rice cookers and IH rice cookers. An ordinary rice cooker is heated by a heating plate at the bottom of the inner pot, which easily causes uneven heating of the inner pot, is not conducive to precise temperature control, and has fewer cooking modes that can be achieved; an IH rice cooker is provided with a coil around the inner pot, so that the electromagnetic field directly acts on the pot body, which can achieve uniform heating in all directions, and different amounts of heat can be generated by controlling the electromagnetic field through a program, which can conveniently achieve precise temperature control and also makes the cooking modes more diverse. Therefore, IH rice cookers are becoming more and more popular, and their sales volume far exceeds that of ordinary rice cookers.

[0003] An IH rice cooker relies on magnetic lines of force to penetrate the pot body for heating. In order to isolate the radiation of the rice cooker, a radiation protection plate usually needs to be installed on the base of the rice cooker. The conventional installation method of the radiation protection plate is to fix the radiation protection plate on the base with self-tapping screws. This fixing method increases the installation difficulty, reduces the production efficiency of the rice cooker, affects the overall production cycle, and increases the production cost to a certain extent.

[0036] Embodiment 1

[0037] See Figure 1-10 As shown, this embodiment discloses an installation structure of a radiation protection plate for a rice cooker, which includes a base 1 and a radiation protection plate 2. The radiation protection plate 2 is provided with at least one card slot 21, and the base 1 is provided with an elastic buckle 11 corresponding to the card slot 21; or

[0038] At least one card slot 21 is provided on the base 1, and an elastic buckle 11 corresponding to the card slot 21 is provided on the radiation protection plate 2;

[0039] Wherein, the elastic buckle 11 is clamped in the card slot 21 so that the base 1 and the radiation protection plate 2 are connected and fixed.

[0040] The radiation protection plate 2 of the installation structure of the radiation protection plate for the rice cooker in this embodiment can be conveniently clamped on the base 1 through the card slot 21 and the elastic buckle 11, greatly simplifying the installation steps of the radiation protection plate 2, reducing the installation difficulty of the radiation protection plate 2, greatly improving the production efficiency of the rice cooker, helping to shorten the production cycle of the rice cooker, and effectively reducing the production cost.

[0041] In this embodiment, the card slots 21 are circularly distributed, and the elastic buckles 11 are also circularly distributed. The circular distribution of the elastic buckles 11 and the card slots 21 ensures the force balance of the radiation protection plate 2, effectively avoids local stress concentration of the radiation protection plate 2, and improves the stability of the installation structure of the radiation protection plate for the rice cooker. In other embodiments, the distribution of the card slots 21 and the elastic buckles 11 can be adjusted according to actual needs or according to the shape of the radiation protection plate 2.

[0042] In this embodiment, at least one card slot 21 is provided on the radiation protection plate 2, and the elastic buckle 11 corresponding to the card slot 21 is arranged on the base 1. The radiation protection plate 2 has excellent radiation protection performance, relatively high price, and great processing difficulty. Arranging the elastic buckle 11 on the base 1 can simplify the processing difficulty and save production costs.

[0043] Specifically, the elastic buckle 11 includes: a support plate 111 and an elastic arm 112; the bottom end of the support plate 111 is connected to the base 1, the elastic arm 112 is bent downward from the top end of the support plate 111, there is a distance between the bottom end of the elastic arm 112 and the base 1, and the distance between the side of the support plate 111 and the elastic arm 112 away from each other is greater than the minimum slot width of the card slot 21; when the elastic buckle 11 is clamped in the card slot 21, the support plate 111 and the elastic arm 112 respectively abut against the opposite side walls of the card slot 21. In the installation structure of the radiation protection plate of the rice cooker in this embodiment, by designing the elastic arm 112 bent and extended from the support plate 111, there is an elastic activity gap between the elastic arm 112 and the support plate 111. When the card slot 21 sleeved on the support plate 111 and the elastic arm 112, the elastic arm 112 is deformed under pressure, and the distance between it and the support plate 111 decreases. The elastic arm 112 under the pressure abuts against the card slot 21 under the action of its own elastic restoring force, restricting the movement of the radiation protection plate 2, making the radiation protection plate 2 firmly connected to the elastic buckle 11, avoiding abnormal noise caused by the loosening of the radiation protection plate 2, and providing strong support for the quality guarantee of the rice cooker.

[0044] In the installation structure of the radiation protection plate of the rice cooker in this embodiment, during specific implementation, the card slot 21 of the radiation protection plate 2 is buckled into the elastic buckle 11, so that the card slot 21 abuts against the support plate 111 and the elastic arm 112 respectively, and the installation of the radiation protection plate 2 on the base 1 is completed. The installation method is simple and efficient; when the radiation protection plate 2 needs to be disassembled, only need to press the elastic arm 112 towards the support plate 111, and the radiation protection plate 2 can be taken out from the elastic buckle 11. The disassembly method is simple and convenient, and no disassembly tool is required.

[0045] Please refer to Figure 7 and Figure 10 , Figure 7 is a schematic structural diagram of the radiation protection plate in the uninstalled state of this embodiment, Figure 10 is a schematic structural diagram of the radiation protection plate in the installed state of this embodiment. The states of the elastic buckle 11 of this embodiment during the buckling process of the card slot 21 include a natural state and a compressed state. The natural state is as shown in Figure 7 , the card slot 21 does not contact the elastic buckle 11, and the bottom end of the elastic arm 112 hangs naturally; the compressed state is as shown in Figure 10As shown, the card slot 21 contacts the support plate 111 and the elastic arm 112. The card slot 21 presses down the elastic arm 112, causing the bottom end of the elastic arm 112 to move towards the support plate 111, resulting in the deformation of the elastic arm 112. At this time, the distance between the bottom end of the elastic arm 112 and the support plate 111 decreases, and the distance between the bottom end of the elastic arm 112 and the base 1 increases. Under the action of its own elastic restoring force, the elastic arm 112 continuously abuts against the card slot 21.

[0046] Specifically, the elastic arm 112 further includes: a guiding portion 1121 and an abutting portion 1122; the guiding portion 1121 extends from the top end of the support plate 111 towards the base 1, and the guiding portion 1121 is arranged in an arc shape or obliquely; one end of the abutting portion 1122 is connected to the end of the guiding portion 1121 away from the support plate 111, and the other end has a spacing from the base 1 and the support plate 111. The guiding portion 1121 is inclined or bent downward from the top of the support plate 111, so that the end of the guiding portion 1121 connected to the support plate 111 is higher than the end connected to the abutting portion 1122. The guiding portion 1121 provides a guiding function for the card slot 21 to slide down along the guiding portion 1121 to the elastic arm 112; and the guiding portion 1121 is arranged obliquely or in an arc shape, facilitating the smooth sliding of the card slot 21 on the guiding portion 1121, thereby improving the smoothness and efficiency of the installation operation.

[0047] In this embodiment, the guiding portion 1121 is arranged obliquely, and the two ends of the guiding portion 1121 with the support plate 111 and the abutting portion 1122 are provided with rounded corners. The obliquely arranged guiding portion 1121 can reduce the guiding path and accelerate the speed of the card slot 21 pressing down the abutting portion 1122, which helps to improve the installation efficiency of the radiation protection plate 2; the connections of the guiding portion 1121 with the support plate 111 and the abutting portion 1122 are both provided with rounded corners, making the guiding portion 1121 smoother, facilitating the dispersion of stress, avoiding the damage of the elastic buckle 11 caused by the impact of the radiation protection plate 2 on the connection, and improving the durability of the elastic buckle 11.

[0048] In this embodiment, the abutting portion 1122 is parallel to the support plate 111. In the natural state, the distance between the top end of the abutting portion 1122 and the support plate 111 is equal to the distance between the bottom end of the abutting portion 1122 and the support plate 111. In the compressed state, the radiation shielding plate 2 presses down the elastic arm 112 through the card slot 21. The card slot 21 is located between the top end and the bottom end of the abutting portion 1122. The bottom end of the abutting portion 1122 approaches the support plate 111, resulting in the distance between the bottom end of the abutting portion 1122 and the support plate 111 being less than the distance between the top end of the abutting portion 1122 and the support plate 111, and the distance between the top end of the abutting portion 1122 and the support plate 111 being greater than the minimum slot width of the card slot 21. At this time, the guiding portion 1121 and the abutting portion 1122 form a limiting tip, which restricts the upward movement of the radiation shielding plate 2 and prevents the radiation shielding plate 2 from detaching from the elastic buckle 11 from above, ensuring the installation stability of the radiation shielding plate 2. In other embodiments, the abutting portion 1122 extends from the guiding portion 1121 in a direction away from the support plate 111 and towards the base 1, that is, in the natural state, the distance between the bottom end of the abutting portion 1122 and the support plate 111 is greater than the distance between the top end of the abutting portion 1122 and the support plate 111. In the compressed state, the distance between the bottom end of the abutting portion 1122 and the support plate 111 is less than the distance between the top end of the abutting portion 1122 and the support plate 111, ensuring that the elastic arm 112 can provide an obliquely downward abutting force on the card slot 21 to prevent the radiation shielding plate 2 from detaching from the elastic buckle 11 above the elastic buckle 11.

[0049] Specifically, the elastic buckle 11 further includes a rib 113; the rib 113 is connected to a side surface of the support plate 111 away from the elastic arm 112. The rib 113 is provided on the side of the support plate 111 away from the elastic arm 112, effectively avoiding the interference of the rib 113 on the deformation of the elastic arm 112, ensuring the smooth deformation of the elastic arm 112, and further ensuring that the card slot 21 can press down the elastic arm 112 to a preset position. The rib 113 is connected to the side of the support plate 111 away from the elastic arm 112, providing additional structural support for the support plate 111, making the elastic buckle 11 more stable when pressed by the radiation shielding plate 2.

[0050] Specifically, the rib 113 is arranged in the vertical direction. The vertical side of the rib 113 is connected to the support plate 111, and the horizontal bottom is connected to the base 1. The vertical height of the rib 113 is less than the vertical height of the support plate 111. The rib 113 connecting the base 1 and the support plate 111 helps to strengthen the supporting force of the support plate 111, thereby improving the structural stability of the support plate 111. The rib 113 is used to limit the downward movement of the radiation shielding plate 2. Specifically, during implementation, the radiation shielding plate 2 presses down the elastic arm 112 through the card slot 21 until the radiation shielding plate 2 abuts against the rib 113. The rib 113 has a limiting function, ensuring the consistency of the downward pressing distance of the radiation shielding plate 2, and avoiding the radiation shielding plate 2 being pressed between the bottom end of the elastic arm 112 and the base 1 due to excessive downward pressure, resulting in difficult disassembly of the radiation shielding plate 2. The rib 113 creates a certain gap between the installed radiation shielding plate 2 and the base 1. This gap can form a relatively stable air layer. The air layer and the radiation shielding plate 2 cooperate with each other and act together to further enhance the radiation shielding effect of the rice cooker, thereby improving the safety and reliability of the rice cooker.

[0051] Specifically, a limiting surface 1131 is provided on the side of the rib 113 away from the support plate 111. The limiting surface 1131 cooperates with the elastic arm 112 to apply forces to the opposite side walls of the card slot 21 respectively. When the card slot 21 is combined with the elastic buckle 11, the elastic arm 112 exerts an elastic force on one side wall of the card slot 21, and the limiting surface 1131 abuts against the opposite side wall of the card slot 21. The elastic arm 112 and the limiting surface 1131 act together to provide two balanced abutting points for the card slot 21, restricting the movement of the card slot 21 in the horizontal direction and preventing the radiation shielding plate 2 from shifting or shaking.

[0052] Specifically, the limiting surface 1131 is an inclined surface or an arc surface. During implementation, the radiation shielding plate 2 presses down the elastic arm 112 until it contacts the rib 113. When the rib 113 is inclined or arc-shaped, the card slot 21 abuts against the waist of the rib 113, and the waist of the rib 113 reacts on the card slot 21, causing the rib 113 and the elastic arm 112 to abut against the card slot 21 from both sides of the elastic buckle 11, improving the installation stability of the radiation shielding plate 2, avoiding loosening of the radiation shielding plate 2, and preventing the radiation shielding plate 2 from generating resonance abnormal noise due to electromagnetic induction. The inclined surface or arc surface enables the rib 113 to adaptively adjust through its gradually changing angle or arc even when facing different specifications or slightly deviated sizes of the card slot 21, thereby ensuring the precise docking of the card slot 21 and the rib 113 and ensuring that the radiation shielding plate 2 is pressed in place. Therefore, the inclined surface or arc surface improves the compatibility, practicality, and application range of the elastic buckle 11.

[0053] In this embodiment, the limiting surface 1131 is an inclined surface, which inclines from the support plate 111 away from the elastic arm 112 and towards the base 1. The width of the rib 113 gradually decreases from the bottom end to the top end, which is beneficial for clamping the card slot 21 and also helps the rib 113 to provide an upward supporting force for the radiation shielding plate 2, preventing the radiation shielding plate 2 from falling onto the base 1 due to loosening.

[0054] Specifically, reinforcing ribs 1111 are provided on both side edges of the support plate 111. The reinforcing ribs 1111 are arranged to avoid the rib 113 and the elastic arm 112 and are located on the vertical plane of the connection surface between the support plate 111 and the rib 113. The reinforcing ribs 1111 are used to improve the strength and stability of the support plate 111.

[0055] Specifically, the reinforcing ribs 1111 extend from both side edges of the support plate 111 towards the base 1 respectively, and the reinforcing ribs 1111 are arranged in an arc shape. The reinforcing ribs 1111 connect the base 1 and the support plate 111, and being arranged in an arc shape can better disperse the pressure from the support plate 111, reduce the concentration of local stress, and prevent the support plate 111 from bending and breaking.

[0056] Specifically, the support plate 111, the guiding portion 1121 and the abutting portion 1122 are integrally formed. The integrally formed setting reduces the connection points between the guiding portion 1121, the support plate 111 and the abutting portion 1122, thus avoiding the rupture of the connection points caused by the long-term clamping of the radiation shielding plate 2 to the elastic buckle 11, and further affecting the structural stability and durability of the elastic buckle 11; and the integrally formed setting makes the force transmission between the abutting portion 1122 and the support plate 111 more uniform and efficient. When the elastic arm 112 is deformed under pressure, the pressure can be transmitted from the abutting portion 1122 through the guiding portion 1121 to the support plate 111, prompting a slight stretch at the top end of the support plate 111 to flexibly adapt to the deformation of the elastic arm 112, improving the toughness and elasticity of the elastic buckle 11; the integrally formed setting can also simplify the production process, reduce the assembly process, and help improve the production efficiency.

[0057] Specifically, the base 1 and the elastic buckle 11 are integrally injection molded. The process of integrally injection molding the base 1 and the elastic buckle 11 greatly simplifies the production process, reduces the assembly steps, thereby improving the production efficiency, and enhancing the connection stability between the base 1 and the elastic buckle 11, making the overall structure more stable and reliable. The radiation shielding plate 2 only needs to be pre-opened with the card slot 21, the production and manufacturing process is simple, the manufacturing difficulty and the required cost are both low, which greatly improves the production efficiency of the rice cooker and saves the production cost at the same time.

[0058] In this embodiment, the base 1 and the elastic buckle 11 are made of ABS or PP materials. The ABS material has high impact strength, excellent dimensional stability, electrical properties, wear resistance, etc., as well as good chemical resistance and molding processing performance. The PP material is characterized by durability, affordability, and high ductility. The base 1 and the elastic buckle 11 made of ABS or PP materials are durable and can undergo a certain degree of elastic deformation when the elastic buckle 11 is subjected to an external force and then quickly return to its original state, ensuring the elasticity and toughness of the elastic buckle 11. In other embodiments, PC, PBT+GF, PET+GF, or other injection molding materials can be used to replace the ABS or PP materials according to actual needs.

[0059] In this embodiment, the card slot 21 is a square slot. The length of the square slot is 6±0.1 mm, and the width of the square slot is 5±0.2 mm; the widths of the support plate 111 and the elastic arm 112 are 5.6±0.1 mm, and the distance between the mutually remote sides of the support plate 111 and the elastic arm 112 is 5.6±0.1 mm; the distance between the bottom end of the elastic arm 112 and the support plate 111 is 3.1±0.1 mm, and the distance between the bottom end of the elastic arm 112 and the base 1 is 0.3±0.1 mm. The short side of the square slot contacts the support plate 111 or the elastic arm 112, and the distance between the mutually remote sides of the elastic arm 112 and the support plate 111 is greater than the minimum slot width of the card slot 21, ensuring that there is a deformable horizontal distance of 0.5 mm for the elastic arm 112. After the card slot 21 slides to the elastic arm 112, the elastic arm 112 provides a large abutting force to stably abut the card slot 21; there is a gap of 0.2 mm between the long side and the elastic buckle 11, facilitating the insertion of the elastic buckle 11 into the card slot 21. In the natural state, the distance between the bottom end of the elastic arm 112 and the support plate 111 is 0.3±0.1 mm, and in the compressed state, the distance between the bottom end of the elastic arm 112 and the support plate 111 is 0.5±0.1 mm. In other embodiments, the shape and size of the card slot 21, the distance between the bottom end of the elastic arm 112 and the support plate 111, and the distance between the bottom end of the elastic arm 112 and the base 1 can be adjusted according to actual needs.

[0060] Specifically, the thickness of the radiation shielding plate 2 is less than the height difference between the elastic arm 112 and the rib 113. Ensure that the radiation shielding plate 2 is clamped between the top end of the elastic arm 112 and the top end of the rib 113, so that the top end of the elastic arm 112 can limit the radiation shielding plate 2 from above, and at the same time, the rib 113 can limit the radiation shielding plate 2 from below, preventing the radiation shielding plate 2 from detaching from the elastic buckle 11 or falling off the base 1.

[0061] In this embodiment, the height of the elastic arm 112 is 5.5 ± 0.1 mm, and the height of the rib 113 is 4 ± 0.1 mm. The thickness of the radiation shielding plate 2 is generally 0.5 - 1 mm, and the 1.5 mm height difference between the elastic arm 112 and the rib 113 provides a generous clamping space for the radiation shielding plate 2, improving the installation accuracy and stability of the radiation shielding plate 2. In other embodiments, the heights of the elastic arm 112 and the rib 113 can be adjusted according to actual needs.

[0062] In this embodiment, the ribs 113 of the elastic buckles 11 distributed in a circular shape are located on the side of the support plate 111 closer to the center of the circle, and the elastic arms 112 are located on the side of the support plate 111 away from the center of the circle. When installing the radiation shielding plate 2, the elastic arms 112 give an outward abutting force to the radiation shielding plate 2, avoiding the concentration of the abutting force at the center of the radiation shielding plate 2, which may cause the plate to break when the radiation shielding plate 2 is unevenly stressed or continuously stressed.

[0063] In this embodiment, the number of both the elastic buckles 11 and the card slots 21 is three. The three elastic buckles 11 provide three connections for the radiation shielding plate 2, ensuring the balance and connection stability of the radiation shielding plate 2 at a relatively low cost. In other embodiments, the numbers of the elastic buckles 11 and the card slots 21 can be adjusted according to actual needs.

[0064] Embodiment Two

[0065] See Figure 1-10 As shown, this embodiment discloses a rice cooker, which includes the radiation shielding plate installation structure of Embodiment One.

[0066] The base 1 of the radiation shielding plate installation structure of the rice cooker is the base 1 of this embodiment of the rice cooker. The radiation shielding plate 2 in the rice cooker is snap-connected to the base 1 through the elastic buckles 11, realizing a convenient and stable connection between the radiation shielding plate 2 and the base 1, improving the production efficiency of the rice cooker, and effectively preventing the radiation shielding plate 2 from loosening or falling off during use, improving the reliability of the rice cooker. In a specific implementation, when installing the radiation shielding plate 2, just align the card slot 21 of the radiation shielding plate 2 with the elastic buckle 11 on the base 1, and then gently press, and the radiation shielding plate 2 will be clamped tightly with the elastic arm 112 and the support plate 111.

[0067] In this embodiment, the radiation shielding plate 2 is an aluminum plate. The aluminum plate has excellent radiation shielding performance, high thermal conductivity, and strong corrosion resistance, and is lightweight and durable, which can improve the durability of the rice cooker while preventing radiation hazards.
