In one embodiment, both bottom heating assembly 10 and side heating assembly 20 are capable of heating inner pot 4 using electromagnetic heating principles after being energized. Thus, the cooking appliance 1 in this embodiment is also called an electromagnetic cooking appliance or an IH cooking appliance. In other embodiments, at least one of the bottom heating assembly 10 and the side heating assembly 20 may be an electrical heating device or other suitable heating device.

The pot 3 further comprises a power panel assembly. The power panel assembly is provided at the rear end of the cooker body 3, and outside of the side heating assembly 20. The power strip assembly can be electrically connected to both the bottom heating assembly 10 and the side heating assembly 20 to supply power to the bottom heating assembly 10 and the side heating assembly 20. Specifically, the power panel assembly includes a power panel and a bracket. The power panel is arranged on the base 5 through a bracket.

In the illustrated embodiment, the bottom heating assembly 10 may include a coil disk 11 and a bottom coil 12. The coil panel 11 is positioned at the bottom of the inner pot 4, and the bottom coil 12 is wound around the coil panel 11.

The side heating assembly 20 may include a heat retaining ring 21 and a side heating member 22. The heat retaining ring 21 can be provided outside the inner pot 4 and at a side portion of the inner pot 4, specifically, the heat retaining ring 21 is located between the middle plate 7 and the coil panel 11. In the illustrated embodiment, the insulating ring 21 may be fixed by clamping the middle plate 7 up and down with the top of the coil disk 11. As shown in fig. 3, the top of the coil disk 11 is provided with a stepped portion 13, and the stepped portion 13 faces inward. The bottom end of the heat preservation ring 21 is limited and is abutted against the step part 13. The side heating element 22 can be arranged on the side of the heat-retaining ring 21 facing away from the inner pot 4 for heating the side of the inner pot 4. The side heating member 22 has two lead ends. Both lead terminals can be connected to the power supply board to achieve electrical connection of the side heating member 22.

In the illustrated embodiment, the side heating element 22 is a side coil, whereby the side of the inner pot can be heated electromagnetically. In other embodiments not shown, the side heating element 22 is a side heating wire or a side heating belt. The side coils are further described herein as examples.

The heat retaining ring 21 is constructed as an opaque member. Further, the heat-insulating ring 21 is opaque at normal temperature, i.e., the heat-insulating ring is invisible at normal temperature. The heat retaining ring 21 is constructed in whole or in part of a thermochromic material. The thermochromic material changes color under the influence of temperature. The heat preservation ring 21 adopts the thermochromic material, so that the heat preservation ring has the thermochromic performance, and is simple in structure and convenient to manufacture and assemble. For example, the thermochromic material in powder form may be injection-molded or injection-molded together with transparent or translucent plastic, glass, or the like, to finally obtain the heat-insulating ring 21 having thermochromic properties.

The heat retaining ring 21 becomes transparent or translucent when its temperature reaches above the color change temperature of the thermochromic material. The heat-insulating ring 21 exhibits an original color at normal temperature and a colorless transparent or semitransparent shape at high temperature. Specifically, when the cooking appliance is not in use, the heat-insulating ring 21 assumes an original color, and a user can only observe the heat-insulating ring 21 when taking out the inner pot (as shown in fig. 1); when the cooking appliance is in use, the heat-insulating ring 21 becomes transparent or translucent when the temperature thereof reaches the discoloration temperature, and a user can observe the side heating member 22 through the heat-insulating ring 21 when taking out the inner pot (as shown in fig. 3).

In this embodiment, the heat generated by the side heating element 22 to the inner pot 4 will raise the temperature of the heat-insulating ring 21, and the heat-insulating ring 21 will become transparent or semitransparent when the temperature reaches a certain value, when the inner pot 4 is taken out, the side heating element 22 can be easily observed by the user from the heat-insulating ring 21, which is beneficial to the user to obtain the function of the product by observing the structure of the product, and the experience of the user is improved; the user can be reminded of the higher temperature of the installation area of the side heating element 22 through the state after color change, so that the user can avoid the installation area and scalding is prevented. Therefore, the safety of the product is higher, and the user experience is improved.

Alternatively, the heat insulating ring 21 is displayed as colorless or one color when its temperature reaches above the color change temperature of the thermochromic material or different colors respectively corresponding to different color change temperatures. The heat retaining ring 21 exhibits an original color at normal temperature and a colorless or identifiable color different from the original color at high temperature. Specifically, when the cooking appliance is not in use, the heat-retaining ring 21 assumes an original color, and when the cooking appliance is in use, the heat-retaining ring 21 appears colorless or a certain color when its temperature reaches the color-changing temperature. For example, the thermochromic material has a color-changing temperature, and the heat-retaining ring 21 shows colorless or one color after being changed in color; or the thermochromic material has more than two color-changing temperatures, and different colors are respectively displayed corresponding to different color-changing temperatures. Thereby, the heat preservation ring 21 can be changed into colorless transparent or colored transparent under the influence of temperature, and the visual effect is better under the condition of colorless transparent; the user can be reminded of the higher temperature of the installation area of the side heating element 22 by the color after color change under the condition of color transparency, so that scalding is prevented.

The thermochromic material has a color-changing temperature T of 45 to 80℃and may be, for example, 45℃50℃55℃60℃65℃70℃75℃80 ℃. Preferably the discoloration temperature T is 50 ℃. Therefore, the heat preservation ring 21 can be subjected to temperature sensing discoloration at the temperature of 45-80 ℃, and scalding of a user is effectively prevented. The side heating member 22 is circumferentially provided to the heat insulating ring 21, and a portion of the heat insulating ring 21 made of a thermochromic material corresponds to the position of the side heating member 22. The portion of the heat insulating ring 21 corresponding to the side heating member 22 can be provided with a thermochromic property, the amount of thermochromic material used is small, the material cost is reduced, and more side heating members 22 can be observed.

In one embodiment, the heat retaining ring 21 may be a separate component. The heat retaining ring 21 is constructed such that the whole or a portion (generally, a lower portion) corresponding to the side heating member 22 is made of a thermochromic material, i.e., the whole or a portion of the heat retaining ring 21 may become transparent or translucent. This embodiment can facilitate the production, manufacture and assembly of the insulation ring 21.

In another embodiment, referring back to fig. 1-4, the heat retainer 21 may be a separate component, e.g., the heat retainer 21 includes an upper heat retainer 23 and a lower heat retainer 24. The lower heat-insulating ring 24 is positioned below the upper heat-insulating ring 23 and is connected with the upper heat-insulating ring. The upper heat-insulating ring 23 is an opaque and thermochromic member. The lower heat-retaining ring 24 is constructed as an opaque member and is made of a thermochromic material, i.e., the lower heat-retaining ring 24 as a whole may become transparent or translucent. The side heating elements 22 are circumferentially disposed on the lower insulation 24.

In this embodiment, the heat insulating ring is constructed in two parts which are independent from each other, wherein the lower heat insulating ring 24 itself as one part has a thermochromic property, can take on a colorless transparent or semitransparent shape at a high temperature, and uses less thermochromic material, thereby reducing material cost. The user can view the side heating element 22 through the lower collar 24. In the scheme that the side heating piece 22 is a side coil, the lower heat-insulating ring 24 which becomes transparent or semitransparent can reflect heat radiated outwards from the inner pot 4 towards the inner pot 4, so that the energy utilization is higher, the heat-insulating effect on the inner pot 2 can be improved, and the rice taste at the inner part of the pot is ensured to be better.

As shown in fig. 5, the lower end of the upper insulation ring 23 may be provided with an annular limiting groove 25. The opening of the limit groove 25 is downward. The upper end of the lower heat-insulating ring 24 can be positioned in the limit groove 25. During assembly, the upper end of the lower insulating ring 24 can be inserted into the limit groove 25. By means of the limiting groove 25, the upper heat-insulating ring 23 and the lower heat-insulating ring 24 can be inserted and fixed with each other, relative movement between the upper heat-insulating ring 23 and the lower heat-insulating ring 24 is limited in the horizontal direction and the vertical direction, and the upper heat-insulating ring 23 and the lower heat-insulating ring 24 can form a whole, so that the upper heat-insulating ring and the lower heat-insulating ring are conveniently installed in the cooker body 3 in a whole, and the assembly efficiency is high.

The lower end of the lower heat preservation ring 24 is provided with an annular limiting part 26. The stopper 26 is configured as a recess opening downward. The top end of the coil disk 11, specifically the step 13, is located in the recess. In other embodiments, not shown, the stop 26 may be configured as an outwardly facing step. The top end of the coil disk 11 is located in the step. By means of the grooves or steps, the lower heat-insulating ring 24 and the coil panel 11 can be clamped and fixed, the coil panel 11 can support the lower heat-insulating ring 24 upwards, and the lower heat-insulating ring 24 is limited to move in the horizontal direction, so that the lower heat-insulating ring 24 is firmly and reliably arranged in the cooker body 3.

As shown in fig. 6, for the illustrated embodiment, the lower insulation 24 may be provided with a plurality of winding buckles 27. A plurality of winding buckles 27 are spaced around the lower insulation ring 24, for example, one ring at equal intervals. The bottom end of the winding buckle 27 is connected with the lower heat-insulating ring 24, specifically with the bottom of the lower heat-insulating ring 24. Further, the winding buckle 27 may have an L-shaped structure. The side coils can be sandwiched between the lower insulation 24 and the winding button 27. Thus, the side coil can be firmly and reliably attached to the lower insulation ring 24 without being detached from the lower insulation ring 24. The tip of the winding button 27 may be provided with a guide structure such as a slope or a rounded corner surface so as to easily wind the side coil into the catching groove between the winding button 27 and the insulation ring 21.

The lower end of the lower insulation ring 24 may also be provided with a supporting portion 28 at a distance for supporting the side coils upward. The support portion 28 protrudes from the outer side surface of the lower insulation ring 24 and extends in a long strip shape in the circumferential direction. The bottom end of the winding buckle 27 is connected to a supporting portion 28. The upper end of the lower heat-insulating ring 24 is also provided with wire clamping parts 29 at intervals, and the leading-out ends of the side coils are clamped after winding is finished, so that the fixing effect is realized. The wire catching portion 29 may be, for example, a U-shaped structure protruding outward. The upper end of the lower insulation ring 24 is further provided with positioning portions 30 protruding upward, 2 positioning portions 30 being schematically shown. The outer side surface of the upper heat-insulating ring 23 is provided with a concave positioning groove (not shown), and the positioning part 30 can be abutted with the positioning groove to be matched and positioned.

Second embodiment

Hereinafter, a pot according to a second embodiment will be described with reference to fig. 7. The pot body of the second embodiment has the same structure and/or construction as the pot body of the first embodiment except for the heat insulation ring. Accordingly, elements having substantially the same functions as those in the first embodiment will be identically numbered herein, and will not be described and/or illustrated in detail for the sake of brevity.

In the present embodiment, the heat retaining ring 21 is configured as a transparent, translucent or partially transparent member. The heat retaining ring 21 is provided with a thermochromic layer 40. The heat preservation ring is transparent or semitransparent, but is invisible under normal temperature due to shielding of the thermochromic layer. The heat preservation ring 21 has the thermochromic property by arranging the thermochromic layer 40, and the thickness of the thermochromic layer 40 is generally smaller, so that the material cost can be reduced. The thermochromic layer 40 is opaque at normal temperature, and when the inner pan is taken out, a user can observe the thermochromic layer 40 of the original color from the heat retaining ring 21. When the thermochromic layer 40 changes color due to the influence of temperature, the user can observe the color change state of the thermochromic layer 40 from the heat insulation ring 21.

The thermochromic layer 40 can become transparent or translucent when its temperature reaches a color change temperature or higher. In this embodiment, the heat generated by the side heating element 22 to the inner pot 4 will raise the temperature of the heat-insulating ring 21, and the temperature of the heat-insulating ring 21 reaches such a temperature that the thermochromic layer 40 becomes transparent or semitransparent, when the inner pot 4 is taken out, the user can easily observe the side heating element 22 from the heat-insulating ring 21, which is beneficial to knowing the function of the product by observing the structure of the product, and improving the experience of the user; the user can be reminded of the higher temperature of the installation area of the side heating element 22 through the state after color change, so that the user can avoid the installation area and scalding is prevented. Therefore, the safety of the product is higher, and the user experience is improved.

The thermochromic layer is colorless or one color or different colors corresponding to different color changing temperatures when the temperature of the thermochromic layer reaches above the color changing temperature. The thermochromic layer 40 takes on an original color at normal temperature and takes on a colorless or identifiable color different from the original color at high temperature. Specifically, the thermochromic layer 40 assumes an original color when the cooking appliance is not in use, and the thermochromic layer 40 exhibits a colorless or a certain color when the temperature thereof reaches the color change temperature when the cooking appliance is in use. For example, the thermochromic layer 40 has a color-changing temperature, and the thermochromic layer 40 shows colorless or one color after being changed in color; or the thermochromic layer 40 has two or more color-changing temperatures, and different colors are respectively displayed corresponding to different color-changing temperatures.

In this scheme, the thermochromic layer 40 can be changed into colorless transparent or colored transparent under the influence of temperature, and the visual effect is better in the case of colorless transparent; the user can be reminded of the higher temperature of the installation area of the side heating element 22 by the color after color change under the condition of color transparency, so that scalding is prevented.

The thermochromic layer 40 corresponds to the position of the side heating member 22. The amount of material forming the thermochromic layer is small, material cost is reduced, and more side heating members 22 can be observed.

The thermochromic layer 40 is arranged on the outer side surface of the heat preservation ring 21, which is back to the inner pot 4, so that the thermochromic layer 40 can be prevented from being scratched and damaged.

In this embodiment, the heat retaining ring 21 may be a separate member or may be a separate member, for example, the heat retaining ring 21 includes an upper heat retaining ring 23 and a lower heat retaining ring 24. In the case of a separate component, the heat retaining ring 21 is provided with a thermochromic layer 40 either entirely or in a portion (typically the lower portion) corresponding to the side heating element 22. In the case of a separate component, the lower heat retaining ring 24 is constructed as a transparent, translucent or partially transparent component and is provided with a thermochromic layer 40. The thermochromic layer 40 is disposed on the outer side surface of the lower insulating ring 24. The user can view the side heating element 22 through the lower collar 24.

The thermochromic layer 40 may be a coating layer formed on the heat retaining ring 21 by printing, coating, or the like. Or may be a thermochromic marker, which may be attached to the heat-insulating ring 21 by means of adhesion or the like. The identification member may be a decal with a thermochromic layer 40 or a sheet of thermochromic material. Of course, the form of the thermochromic layer 40 is not limited.
