[0028] An embodiment of the present application provides a ceramic rice cooker.

[0029] See also Figures 1 to 4 The embodiment of the present application provides a ceramic rice cooker 100, comprising a ceramic inner pot 10, a heat conducting device 20 and a shell assembly 30, wherein the ceramic inner pot 10 has a receiving space, and an abutting step 11 is provided at the outer edge of the upper end of the ceramic inner pot 10; the heat conducting device 20 comprises a cover body 21, a partition plate 22 and a buffer device 23, wherein a surface of the cover body 21 close to the ceramic inner pot 10 is adapted to and fits the shape of the ceramic inner pot 10, the upper end of the cover body 21 is provided with a step surface 211, the abutting step 11 abuts against the step surface 211, the partition plate 22 is arranged between the ceramic inner pot 10 and the bottom of the cover body 21, and the buffer device 23 is arranged between the partition plate 22 and the bottom of the cover body 21; the shell assembly 30 is arranged on the outside of the heat conducting device 20, and the shell comprises a heating device 31, which provides heat for the heat conducting device 20.

[0030] The ceramic inner container 10 is generally cylindrical, but may also be of other shapes. The storage space of the ceramic inner container 10 is used to directly hold and heat food. The ceramic inner container 10 has good heat preservation performance and uniform heating characteristics, which helps to maintain the nutritional content and taste of the food.

[0031] The housing assembly 30 is mounted outside the heat-conducting device 20, protecting the internal components, providing an operational interface, and maintaining the overall appearance. The housing assembly 30 typically includes a base, side panels, and heating components. These components not only protect the internal circuitry and heating elements but also provide a user interface, such as a control panel and display. Furthermore, the heating device 31 provides heat for the heat-conducting device 20.

[0032] The heat conducting device 20 includes a cover 21, a partition 22, and a buffer device 23. The side of the cover 21 close to the ceramic inner pot 10 is adapted to and fits the shape of the ceramic inner pot 10. The upper end of the cover 21 is provided with a step surface 211, and the abutting step 11 abuts against the step surface 211. The partition 22 is provided between the ceramic inner pot 10 and the bottom of the cover 21, and the buffer device 23 is provided between the partition 22 and the bottom of the cover 21. Since the buffer device 23 is provided between the partition 22 and the cover 21 in the present application, the ceramic inner pot 10 is not easily damaged when installed and placed. At the same time, there is a grid plate between the cover 21 and the ceramic inner pot 10. When in the heat preservation state, it is not easy to damage other electrical controls of the rice cooker, thereby avoiding safety risks.

[0033] In some embodiments, the buffer device 23 is a buffer spring, and a mounting post 221 is provided on the side of the partition plate 22 facing the bottom of the cover body 21. The buffer spring is sleeved on the mounting post 221, and the mounting post 221 is fixedly connected to the bottom of the cover body 21.

[0034] The buffer device 23 here refers to a buffer spring, an elastic element used to absorb or reduce forces generated by thermal expansion, mechanical vibration, or impact. In an electric rice cooker, the buffer spring may be used to reduce stress between the ceramic inner pot 10 and the cover 21 caused by temperature changes, as well as to mitigate shock during mechanical operation. The spacer 22 is a component located between the ceramic inner pot 10 and the bottom of the cover 21. It may provide thermal insulation or support for the ceramic inner pot 10. Mounting posts 221 are provided on the side of the spacer 22 facing the bottom of the cover 21. These posts 221 are used to secure the spacer 22 and ensure its position. The mounting posts 221 not only secure the spacer 22 but also house the buffer spring. This means that the buffer spring is mounted around the mounting posts 221, providing elastic support between the spacer 22 and the bottom of the cover 21. The fixed connection between the mounting posts 221 and the bottom of the cover 21 ensures the stability of the entire structure. This fixing method can be welding, threading, or other mechanical connection to ensure that the spacer 22 and the buffer spring do not loosen or shift during use of the rice cooker.

[0035] In some embodiments, a positioning post 222 is provided on one side of the partition plate 22 facing the bottom of the cover body 21 . A positioning hole 212 is provided at the bottom of the cover body 21 . The positioning post 222 is located in the positioning hole 212 .

[0036] The side of the partition plate 22 facing the bottom of the housing 21 is provided with a positioning post 222, which is located within a positioning hole 212 provided at the bottom of the housing 21. This design ensures a precise fit and secure connection between the partition plate 22 and the housing 21. The alignment of the positioning post 222 and the positioning hole 212 ensures the precise positioning of the partition plate 22 within the housing 21, thereby ensuring the structural stability and proper function of the entire rice cooker.

[0037] In some embodiments, the tail portion 25 is snap-connected to the step surface.

[0038] The outer side of the upper end of the housing 21 is provided with a mounting step, which serves as a structural component for connecting to the housing assembly 30. This design ensures securement and alignment between the housing assembly 30 and the housing 21, facilitating installation and removal. The housing assembly 30 and the mounting step are connected via a snap-fit ​​connection. This simple and effective connection allows for quick attachment of the housing assembly 30 to the housing 21 while also facilitating removal and maintenance.

[0039] In some embodiments, a through hole 24 is defined in the middle of the bottom of the cover body 21 , and the heating device 31 includes a heating disk, which is located in the through hole 24 .

[0040] The bottom of the cover 21 is provided with a through hole 24, which is mainly used to accommodate the heating plate. The heating plate is the main heating component of the rice cooker. It is located in the through hole 24 and directly contacts the ceramic inner pot 10, transferring heat energy to the inner pot, thereby heating the food inside the inner pot.

[0041] In some embodiments, the heat conducting device 20 further includes a tail portion 25 , which extends along the outer side of the step surface 211 toward the bottom of the cover body 21 , and the tail portion 25 is parallel to the cover body 21 .

[0042] The tail portion 25 is parallel to the housing 21. This parallel structure helps maintain uniform and continuous heat transfer, preventing localized heat accumulation during heat transfer, thereby improving heat dissipation efficiency. The main function of the tail portion 25 is to effectively conduct and dissipate heat generated by the housing 21 and the ceramic inner pot 10 during heating, thereby maintaining the temperature of the rice cooker housing assembly 30 within a safe range and preventing overheating.

[0043] In some embodiments, the tail portion 25 extends to a length corresponding to that of the housing assembly 30 .

[0044] The tail 25 extends to a length corresponding to the housing assembly 30, which means that the design and layout of the tail 25 need to match the housing assembly 30 to ensure heat dissipation efficiency and the compactness of the overall structure. This design allows the tail 25 to effectively absorb and dissipate the heat generated when the rice cooker is working, while preventing the heat from being directly conducted to the circuit board, thereby protecting the electronic components on the circuit board.

[0045] In some embodiments, a gap 40 is defined between the tail portion 25 and the cover body 21 .

[0046] The gap 40 between the tail 25 and the cover 21 can increase air flow, thereby improving heat dissipation efficiency. This design allows air to circulate between the tail 25 and the cover 21, helping to dissipate the heat generated by the cover 21 and the ceramic liner 10 during the heating process. By providing a gap 40 between the tail 25 and the cover 21, the heat dissipation efficiency can be effectively improved. This design allows heat to be quickly dissipated through the tail 25, reducing the temperature of the outer shell assembly 30 during operation of the rice cooker and improving safety in use.

[0047] In some embodiments, the cover body 21 and the tail portion 25 are integrally formed.

[0048] The tail portion 25 and the cover 21 are integrally formed, which ensures overall structural stability, avoids gaps between different components, and improves overall durability and reliability. The integrally formed design can further reduce the overall thickness in terms of space occupation, making the rice cooker more compact and space-saving.

[0049] In some embodiments, a ceramic cover 50 is further included, and the ceramic cover 50 is covered on the ceramic inner container 10.

[0050] An embodiment of the present application provides a ceramic rice cooker 100, comprising a ceramic inner pot 10, a heat-conducting device 20 and a shell assembly 30, wherein the ceramic inner pot 10 has a receiving space, and an abutting step 11 is provided at the outer edge of the upper end of the ceramic inner pot 10; the heat-conducting device 20 comprises a cover body 21, a partition plate 22 and a buffer device 23, a surface of the cover body 21 close to the ceramic inner pot 10 is adapted to and fits the shape of the ceramic inner pot 10, a step surface 211 is provided at the upper end of the cover body 21, the abutting step 11 abuts against the step surface 211, the partition plate 22 is arranged between the ceramic inner pot 10 and the bottom of the cover body 21, and the buffer device 23 is arranged between the partition plate 22 and the bottom of the cover body 21; the shell assembly 30 is arranged on the outside of the heat-conducting device 20, and the shell comprises a heating device 31, which provides heat for the heat-conducting device 20. Since a buffer device 23 is provided between the partition plate 22 and the cover body 21 in the present application, the ceramic inner pot 10 is not easily damaged when installed and placed. At the same time, there is a grid plate between the cover body 21 and the ceramic inner pot 10, which is not easy to damage other electrical controls of the rice cooker when in the heat preservation state, thereby avoiding safety risks.
