The heat-insulating ring assembly 21 can be disposed outside the inner pan 4 and at a side portion of the inner pan 4, specifically, the heat-insulating ring assembly 21 is located between the middle plate 7 and the coil panel 11. In the illustrated embodiment, the insulating ring unit 21 may be fixed by clamping the middle plate 7 to the top of the coil disk 11 up and down. The top of the coil disk 11 is provided with a step portion 13, and the step portion 13 faces inward.

In this embodiment, as shown in fig. 2 to 4, the heat-insulating ring unit 21 includes a single-layer heat-insulating ring 23 and a double-layer heat-insulating ring 30. The double-layer insulation ring 30 can be arranged up and down and connected with the single-layer insulation ring 23. The double-layered heat-insulating ring 30 may include an inner heat-insulating ring 31 and an outer heat-insulating ring 32, the outer heat-insulating ring 32 being located outside the inner heat-insulating ring 31 and both being configured as transparent, translucent or partially transparent members. That is, the double layer insulation ring 30 may be entirely transparent or translucent, may be partially transparent, or may be partially translucent. Wherein in embodiments where the dual-layer insulation ring 30 is partially transparent or translucent, a portion of the outer insulation ring 32 and the inner insulation ring 31 are made of a transparent material. The side coil 22 can be arranged on the side of the outer insulation collar 32 facing away from the inner pot 4.

In this embodiment, the insulating ring is constructed as two separate parts, one of the separate parts being constructed as a double layer structure and being transparent, translucent or partially transparent. Therefore, the heat of the outer pot can be prevented from radiating outwards by forming a double-layer structure, and the heat insulation effect of the double-layer structure is better; through being constructed transparent, semitransparent or local transparent, can be with the heat reflection of the outside radiation of interior pot 4 towards interior pot 4, can improve the heat preservation effect to interior pot 4 from this, guarantee that the rice taste of pot inboard department is better to can also have visual effect, when taking out interior pot 4, the user can observe lateral coil 22 from bilayer heat preservation circle 30 department easily, is favorable to the user to know the structure of product, promotes user's experience and feels.

And the heat-insulating ring having a double-layer structure includes two parts, whereby different transparent materials can be selected for the outer heat-insulating ring 32 and the inner heat-insulating ring 31, respectively, and the outer heat-insulating ring 32 can be selected for a transparent material having a lower price than that of the transparent material of the inner heat-insulating ring 31, which can reduce material costs.

Alternatively, in other embodiments, the inner insulation ring 31 may be provided with a plurality of first partially transparent parts at intervals in the circumferential direction thereof, and the outer insulation ring 32 may be provided with a plurality of second partially transparent parts at intervals in the circumferential direction thereof. The first partially transparent portion and the second partially transparent portion can be positioned in correspondence. The double-layer insulation ring 30 can thus be transparent at a plurality of points in the circumferential direction, so that heat radiated outwards from the inner pot 4 can be reflected at intervals in the circumferential direction towards the inner pot 4. The term "plurality" as used herein means two or more.

The heat resistant temperature of the material used to make the inner insulation ring 31 is T1, and the heat resistant temperature of the material used to make the outer insulation ring 32 is T2, T1> T2. As shown in fig. 2, the inner heat-retaining ring 31 is located closer to the inner pan 4 than the outer heat-retaining ring 32, and can block a part of heat from being transferred to the outer heat-retaining ring 32. Thus, the inner insulation ring 31 can be made of transparent material with higher heat resistance, such as PPSU

(Polyphenylene sulfone ), PES (polyether sulfone), high-temperature nylon and other suitable high-temperature-resistant transparent materials, and the outer insulation ring 32 is made of transparent materials with lower heat resistance, such as transparent PC (Polycarbonate), PP (polypropylene) and other suitable common transparent materials. Compared with the high-temperature-resistant transparent material, the common transparent material has low cost, and can reduce the material cost.

The inner insulation ring 31 can be made of transparent material with heat-resistant temperature greater than or equal to 140 ℃, namely, T1 is greater than or equal to 140 ℃. The outer insulation 32 may be made of a transparent material having a heat resistance temperature of less than 140 ℃, that is, T2<140 ℃. Therefore, the inner heat preservation ring 31 and the outer heat preservation ring 32 can be not influenced by the high temperature of the inner pot 4, so that the heating requirement of the inner pot 4 during cooking can be met, and the temperature of the inner pot 4 can reach a higher level.

In the illustrated embodiment, the single layer insulation ring 23 may be positioned above the double layer insulation ring 30, whereby the single layer insulation ring 23 may be referred to as an upper insulation ring and the double layer insulation ring 30 may be referred to as a lower insulation ring. The upper end of the single-layer insulation ring 23 can be fixed to the middle plate 7, and the lower end of the double-layer insulation ring 30 can be fixed to the coil disk 11. The diameter of the upper end of the single-layer insulation ring 23 may be smaller than the diameter of the lower end thereof and smaller than the diameter of the double-layer insulation ring 30. This minimizes the gap between the heat retainer assembly 21 and the inner pan 4 at the top thereof, whereby the heat retainer assembly 21 can block heat flowing from the bottom up between the side of the inner pan 4 and the heat retainer assembly 21 at the top thereof, and can also reflect the heat flowing from the bottom up toward the inner pan 4, effectively avoiding heat loss from the position of the pan opening, further improving the heat retaining effect on the inner pan 4.

For embodiments where single layer insulation collar 23 is positioned above double layer insulation collar 30, single layer insulation collar 23 includes sloped wall portion 24 and straight wall portion 25 positioned therebelow, as shown in fig. 5. The inclined wall portion 24 may be an inclined wall extending in the vertical direction and inclined from the lower side up toward the inner pan 4. Further, the diameter of the inclined wall portion 24 gradually decreases from bottom to top so that a portion of the single-layer insulation ring 23 has a tapered shape. This causes the gap between the single-layer heat-insulating ring 23 at the inclined wall portion 24 and the inner pan 4 to gradually decrease from bottom to top, and further, the gap between the single-layer heat-insulating ring 23 at the top thereof and the inner pan 4 is minimized. The straight wall portion 25 is a straight wall extending in the vertical direction, and further, the straight wall portion 25 is the same in diameter so that a part of the single-layer insulation ring 23 takes a straight cylindrical shape.

The double-layered insulation ring 30 may have the same diameter except for the upper and lower ends. Specifically, the portions of the inner insulation ring 31 other than the upper and lower ends may have the same diameter, and the portions of the outer insulation ring 32 other than the upper and lower ends may have the same diameter. In other words, the inner insulation ring 31 is substantially in the shape of a straight cylinder, and the outer insulation ring 32 is also substantially in the shape of a straight cylinder.

In other embodiments, not shown, double layer insulation 30 is positioned over single layer insulation 23, whereby double layer insulation 30 may be referred to as an upper insulation and single layer insulation 23 may be referred to as a lower insulation. The upper end of the double-layer insulation ring 30 can be fixed to the middle plate 7, and the lower end of the single-layer insulation ring 23 can be fixed to the coil disk 11. The diameter of the upper end of the double layer insulation ring 30 may be smaller than the diameter of the lower end thereof and smaller than the diameter of the single layer insulation ring 23.

For embodiments where double-layer insulation 30 is located above single-layer insulation 23, inner insulation 31 and outer insulation 32 may include sloped wall portions 24 and straight wall portions 25 located therebelow. The inclined wall portion 24 may be an inclined wall extending in the vertical direction and inclined from the lower side up toward the inner pan 4. The inner and outer insulation rings 31 and 32 have a tapered shape at a part and a straight cylindrical shape at a part. This causes the gap between the double-layered heat-retaining collar 30 at the inclined wall portion 24 and the inner pan 4 to gradually decrease from bottom to top, and further, the gap between the double-layered heat-retaining collar 30 at the top thereof and the inner pan 4 is minimized. The single-layer insulation ring 23 may have the same diameter except for the upper and lower ends. In other words, the single-layer insulation ring 23 has a substantially straight cylindrical shape.

The side coils 22 may be wound in at least one of a single layer, a double layer, and a multiple layer to form a single layer coil, a double layer coil, a multiple layer coil, or a combination of these layers. The side coil 22 may include an enamel wire and an outer covering that wraps the enamel wire. The overwrap may be an outer adhesive shell, an outer adhesive tape, or the like. The overwrap is an insulating member and is configured as a transparent or translucent member. Further, the material of the outer wrapping piece is an insulating material and can be a proper material such as transparent plastic or semitransparent plastic. The outer wrapping member is transparent, so that the outer wrapping member also has the effect of reflecting heat, and can reflect the heat radiated outwards from the inner pot 4 towards the inner pot 4, thereby further improving the heat preservation effect on the inner pot 4.

Enamelled wires may be members that exhibit metallic luster. For example, the enamel wire may exhibit any suitable metallic luster such as gold, etc. When taking out the inner pot 4, the user can observe from double-deck heat preservation circle 30 department easily that the enameled wire presents metallic luster, and the visual impression of product is better, is favorable to promoting user's experience and feels.

As shown in fig. 5, the thickness of the inner insulation ring 31 is D1, and the thickness of the outer insulation ring 32 is D2, D1< D2. This can reduce the expensive transparent material used to manufacture the inner insulation 31, thereby further reducing material costs.
