[0002] A rice cooker is a household appliance used to simplify the traditional rice cooking process. It automatically completes functions such as cooking and keeping warm through built-in heating elements and temperature control systems. The design of a rice cooker usually includes an outer shell, an inner pot, a heating plate, a temperature control device, and an insulation layer. Among them, the inner cover of the rice cooker is an important component, which is usually connected to the upper cover and seals the inner pot during the cooking process. The design of the inner cover may include vents that allow steam to escape during the cooking process while maintaining a suitable internal pressure, which helps the rice to be evenly cooked and matured. The inner covers of some rice cookers are removable, which is designed to facilitate cleaning.

[0046] Third embodiment

[0047] like Figure 1 , Figure 2 and Figure 4 This is an embodiment of the present invention. By setting a pushing block 17 at the edge of the lower mold body 13, the upper mold base 2 is pressed to the top of the pushing block 17 during the descent process, and the pushing block 17 is compressed into the interior of the embedded groove 16. At this time, the inner cover plate enters the surface of the top of the lower mold body 13. After the stamping is completed, the upper mold base 2 moves up. At this time, the unloading spring 110 pushes the pushing block 17 to rise through its own reaction force. At this time, the pushing block 17 pushes the inner cover of the rice cooker inside the lower mold body 13 upward, so that the inner cover of the rice cooker moves out of the interior of the lower mold body 13. At the same time, the pushing spring 19 pushes the inner cover of the rice cooker upward through its own reaction force, and the upper rocker plate 18 pushes the inner cover of the rice cooker upward, so that the inner cover of the rice cooker moves up, thereby facilitating the unloading of the inner cover of the rice cooker.

[0048] Among them, a plurality of embedded grooves 16 are opened at the edge of the top of the lower mold body 13, and a pushing block 17 is movably sleeved inside the embedded groove 16.

[0050] During the process of descending, the upper mold base 2 is pressed to the top of the push block 17, and the push block 17 is compressed and enters the inside of the embedded groove 16. At this time, the inner cover plate enters the surface of the top of the lower mold body 13. After the stamping is completed, the upper mold base 2 moves up. At this time, the unloading spring 110 pushes the push block 17 up through its own reaction force. At this time, the push block 17 pushes the inner cover of the rice cooker inside the lower mold body 13 upward, so that the inner cover of the rice cooker moves out of the lower mold body 13. At the same time, the push spring 19 pushes the inner cover of the rice cooker upward through its own reaction force, so that the upper swing plate 18 moves the inner cover of the rice cooker upward, thereby facilitating the unloading of the inner cover of the rice cooker.

Similarly, when disassembling, the fixing bolt 38 is taken out, and the heat dissipation hole punch 36 is pushed upward from the bottom to move the fixing block 35 out of the mounting groove 33, and the fixing block 35 is taken out and replaced. When disassembling the bottom heat dissipation hole module 112, the lifting column 106 drives the extrusion block 109 to descend by rotating the adjusting screw 105, and presses the bottom heat dissipation hole module 112 downward to disengage the bottom heat dissipation hole module 112 from the bottom embedding groove 103. Inside, at this time, the inlaid spring 107 is reset, and the movable rod 108 pushes the pushing plate 111, so that the pushing plate 111 pushes the bottom heat dissipation hole module 112 out of the inside of the placement slot 101, and the bottom heat dissipation hole module 112 is taken out. Similarly, when installing the bottom heat dissipation hole module 112, the bottom heat dissipation hole module 112 is placed inside the placement slot 101, and the bottom heat dissipation hole module 112 is pushed to compress the inlaid spring 107, and the pushing plate 111 moves to the side of the extrusion block 109. At this time, the bottom heat dissipation hole module 112 stays below the bottom embedded groove 103. By rotating the adjusting screw 105, the lifting column 106 drives the extrusion block 109 to rise, so that the bottom heat dissipation hole module 112 is clamped in the inside of the bottom embedded groove 103, and the installation of the bottom heat dissipation hole module 112 is completed.
