Description

Technical Field

[0001] This utility model relates to the field of rice cooker technology, specifically to a rice cooker heat conduction component and a rice cooker. Background Technology

[0002] An electric rice cooker is a modern cooking appliance capable of steaming, boiling, stewing, simmering, and braising. It not only cooks food but also keeps it warm. It is clean, hygienic, and pollution-free to use, saving time and effort, making it an indispensable tool for modern household chores.

[0003] Traditional rice cookers typically have their heating element located at the bottom of the inner pot. The heating element heats the inner pot to cook the rice. This method results in uneven heating because the bottom of the inner pot is heated first, and the heat is then transferred upwards. Furthermore, the high heat at the bottom makes the rice sticky and prone to burning. In addition, existing rice cookers have poor heat retention. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, one of the objectives of this utility model is to invent a heat-conducting component for a rice cooker that can heat the inner pot evenly and has a good heat preservation effect.

[0005] One of the objectives of this utility model is achieved through the following technical solution:

[0006] A heat-conducting component for a rice cooker, comprising:

[0007] The heat-conducting base includes a heating plate and at least two arc-shaped heat-conducting sheets. The two heat-conducting sheets cooperate to form a heating cavity for accommodating the inner liner. The inner side of the heat-conducting sheets is provided with multiple mounting slots for mounting the heating sheets. The heat-conducting sheets are made of solid-solid phase change material. The heating plate is installed at the bottom of the heating cavity to heat the bottom of the inner liner.

[0008] A heating element is disposed within the mounting groove to heat the side wall of the inner liner.

[0009] Furthermore, the heat-conducting plate is made of ceramic material, the inner diameter of the heat-conducting plate is adapted to the outer diameter of the inner liner, and the heating cavity is bowl-shaped to fit the bottom of the inner liner.

[0010] Furthermore, a fixing seat extends inward from the bottom inner side of the heat-conducting sheet, and the fixing seat engages with the outer side of the heating plate via a snap-fit.

[0011] The second objective of this utility model is achieved through the following technical solution:

[0012] An electric rice cooker includes a body, a lid, an inner pot, and the aforementioned electric rice cooker heat-conducting assembly. The body has an inner cavity with an upper opening. One end of the lid is rotatably mounted on the body and is adapted to seal the upper opening. The inner pot is disposed within the inner cavity and forms a gap with the inner cavity. The heat-conducting seat is disposed at the lower part of the gap and is sleeved on the outside of the inner pot.

[0013] Furthermore, the bottom surface of the inner liner is concave, and the top surface of the heating plate is formed with a convex surface that matches the concave surface.

[0014] Furthermore, a chamfer is formed on the inner side of the upper edge of the heat-conducting sheet.

[0015] Furthermore, a sealing ring is installed on the cover, which is adapted to fit against the opening of the inner liner to seal the inner liner when the cover blocks the upper opening.

[0016] Furthermore, the outer side of the heat-conducting seat abuts against the inner wall of the inner cavity.

[0017] Furthermore, it also includes a controller disposed within the main body and a control panel disposed on the surface of the cover, wherein the controller is electrically connected to the control panel, the heating element, and the heating plate.

[0018] Beneficial effects:

[0019] This application utilizes a heating element that works in conjunction with a heating plate to heat the sides and bottom of the inner pot. This ensures even heating of the food inside the inner pot and allows for rapid cooking, facilitating quick meals. When the temperature inside the inner pot reaches its upper limit (100±2 degrees Celsius), energy consumption is reduced through the use of heat-conducting elements, preventing the food from burning due to rapid drying of moisture. Furthermore, the heat-conducting elements, made of solid-solid phase change material, absorb and store heat dissipated from the outer wall of the inner pot during heating and release it when heating stops, thus maintaining the inner pot's temperature and extending its heat retention time.

[0029] like Figure 1-3 As shown, a heat-conducting component for a rice cooker includes,

[0030] The heat-conducting base 10 includes a heating plate 102 and at least two arc-shaped heat-conducting sheets 101. The two heat-conducting sheets 101 cooperate to form a heating cavity for accommodating the inner liner 40. The inner side of the heat-conducting sheet 101 is provided with a plurality of mounting slots 1011 for mounting the heating sheet 103. The heat-conducting sheet 101 is made of solid-solid phase change material. The heating plate 102 is installed at the bottom of the heating cavity to heat the bottom of the inner liner 40.

[0031] Heating element 103 is disposed in the mounting groove 1011 to heat the side wall of the inner liner 40.

[0032] When the heat-conducting component of the rice cooker of this application is working, the bottom end of the inner pot 40 is placed in the heating cavity. The heating element 103 and the heating plate 102 simultaneously heat the sides and bottom of the inner pot 40 to ensure that the inner pot 40 is heated evenly and effectively improve the heating speed of the inner pot 40. When the temperature inside the inner pot 40 reaches 100°C, the heating element 103 installed in the mounting slot 1011 will stop working. At this time, only the heating plate 102 heats the inner pot 40 to reduce energy consumption. During the heating process of the inner pot 40, the heat dissipated from the inner pot 40 will be collected and stored by the heat-conducting element 101. After the heating element 103 and the heating plate 102 stop working, the heat-conducting element 101 will release the stored heat to keep the inner pot 40 warm and extend the heat preservation time.

[0033] This application utilizes a heating element 103 in conjunction with a heating plate 102 to heat the sides and bottom of the inner pot 40. This ensures even heating of the food inside the inner pot 40 and allows for rapid heating, facilitating quick meals. When the temperature inside the inner pot 40 reaches its upper limit of 100±2 degrees Celsius, energy consumption is reduced via the heat-conducting element 101. This also prevents the food from burning due to rapid drying of moisture inside the inner pot 40. Furthermore, the heat-conducting element 101, made of a solid-solid phase change material, absorbs and stores the heat dissipated from the outer wall of the inner pot 40 during heating and releases it when heating stops, thus maintaining the temperature of the inner pot 40 and extending its heat retention time.

[0034] Specifically, in this embodiment, the heat-conducting sheet 101 is made of ceramic material, which has low material cost and good heat storage effect. In order to improve the heat absorption efficiency of the heat-conducting sheet 101, the inner diameter of the heat-conducting sheet 101 is adapted to the outer diameter of the inner liner 40, and the heating cavity is bowl-shaped to fit the bottom of the inner liner 40. With this arrangement, the heat-conducting sheet 101 can be completely attached to the outer wall of the inner liner 40, thereby improving the heat absorption efficiency of the heat-conducting sheet 101. In addition, it can prevent water vapor generated during the heating process from entering the mounting groove 1011 from the gap between the heat-conducting sheet 101 and the inner liner 40, causing corrosion to the heat-conducting sheet 101 in the mounting groove 1011 and shortening the service life of the heat-conducting sheet 101.

[0035] Furthermore, to ensure a tighter connection between the heat-conducting plate 101 and the heating plate 103, in this embodiment, a fixing seat 1012 extends inward from the bottom inner side of the heat-conducting plate 101. The fixing seat 1012 engages with the outer side of the heating plate 102 via a snap-fit ​​mechanism, thereby connecting the heating plate 103 and the heat-conducting plate 101 as a whole, thus preventing the heating plate 103 and the heat-conducting plate 101 from separating during use. In this embodiment, the contact surfaces of the two heat-conducting plates 101 are provided with matching slots and sockets, which connect the two heat-conducting plates 101 as a whole through a plug-in engagement. The diameter of the inner cavity 201 of the rice cooker is matched with the outer diameter of the heat-conducting plate 101. After the heat-conducting seat 10 is placed into the inner cavity 201, the cavity wall of the inner cavity 201 will abut against the outer wall of the heat-conducting plate 101, thereby preventing the two heat-conducting plates 101 from separating during use.

[0036] like Figure 2 and Figure 3 As shown, in this embodiment, a rice cooker is also disclosed, including a body 20, a lid 30, an inner pot 40, and the above-mentioned rice cooker heat conduction assembly. The body 20 has an inner cavity 201 with an upper opening. One end of the lid 30 is rotatably mounted on the body 20 and is adapted to block the upper opening. The inner pot 40 is disposed in the inner cavity 201 and a gap is formed between it and the inner cavity 201. The heat conduction seat 10 is disposed at the lower part of the gap and is sleeved on the outside of the inner pot 40.

[0037] During operation, the inner pot 40 is placed inside the inner cavity 201, with the lower half of the inner pot 40 placed inside the heat-conducting seat 10. When heating, the heating element 103 and the heating plate 102 can simultaneously heat the sides and bottom of the inner pot 40, so that the inner pot 40 is heated evenly, effectively improving the heating speed of the inner pot 40 and achieving the purpose of quick dining.

[0038] This application utilizes a heating element 103 in conjunction with a heating plate 102 to heat the sides and bottom of the inner pot 40. This ensures that the food inside the inner pot 40 is heated evenly and quickly, facilitating rapid consumption. Simultaneously, the heating element 103 is positioned on a heat-conducting plate 101. This allows the heat-conducting plate 101 to absorb heat dissipated from the heating element 103 and the inner pot 40, while also protecting the heating element 103 from corrosion caused by water vapor generated during heating. After the heating element 103 and heating plate 102 cease operation, the heat-conducting plate 101 releases stored heat to maintain the temperature of the inner pot 40, extending the heat preservation time.

[0039] Preferably, in order to enhance the heating effect, in this embodiment, the bottom surface of the inner liner 40 is a concave surface, and the top surface of the heating plate 102 is formed with a convex surface that matches the concave surface, thereby enhancing the heating effect of the heating plate 102 by increasing the heating surface at the bottom of the inner liner 40.

[0040] In addition, to facilitate the placement of the inner liner 40 into the heating cavity, a chamfer is formed on the inner side of the upper edge of the heat-conducting sheet 101 in this embodiment. When the inner liner 40 is placed in, the chamfer can provide guidance for the inner liner 40, thereby facilitating the inner liner 40 to enter the heat-conducting cavity.

[0041] Preferably, to prevent steam generated during heating from entering the inner cavity 201 and corroding the heating element 103 and heating plate 102, a sealing ring 301 is installed on the cover 30 in this embodiment. The sealing ring 301 is adapted to fit against the opening of the inner liner 40 when the cover 30 blocks the upper opening to seal the inner liner 40, thereby separating the inner liner 40 from the inner cavity 201 during heating, thus preventing steam from entering the inner cavity 201 and corroding the heating element 103 and heating plate 102.

[0042] In addition, to prevent the two heat-conducting plates 101 from separating during use, in this embodiment, the diameter of the inner cavity 201 of the rice cooker is adapted to the outer diameter of the heat-conducting plate 101. After the heat-conducting base 10 is placed into the inner cavity 201, the cavity wall of the inner cavity 201 will abut against the outer wall of the heat-conducting plate 101, thereby restricting the movement of the heat-conducting plate 101. Combined with the slots and sockets provided on the contact surfaces of the two heat-conducting plates 101, the two heat-conducting plates 101 are firmly connected together.

[0043] Meanwhile, to allow users to selectively turn off the heating element 103 or the heating plate 102 according to their needs, in this embodiment, the rice cooker also includes a controller disposed in the main body 20 and a control panel disposed on the surface of the lid 30. The controller is electrically connected to the control panel, the heating element 103 and the heating plate 102. In addition, a temperature sensor electrically connected to the controller is disposed in the main body 20. The temperature sensor can detect the temperature inside the inner pot 40 and transmit it to the controller in real time, so that the controller can control the heating element 103 to turn off when the temperature inside the inner pot 40 reaches the upper limit, thereby reducing energy consumption.

[0044] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
