In a specific embodiment, the total length of the partial heat generation section is equal to or greater than 50% of the total length of the plurality of heat generation sections.

In the design, the total length of the partial heating section is the heating section with the distance from the inner wall surface of the inner pot opening being less than or equal to 25 mm. When the total length of the plurality of heating sections (the outermost heating members 13) is L, the total length of the partial heating sections is 0.5L, that is, the partial heating sections having a distance of 25mm or less from the inner wall surface of the inner pot opening account for 50% of the plurality of heating sections constituting the outermost heating members 13. This can further ensure the heating effect of the outermost heat generating member 13 on the edge of the thermal insulation seat plate 12 and the sealing structure.

Detailed description of the preferred embodiments

In the present embodiment, the positional relationship between the cover plate 11 and the heat-insulating seat plate 12 is provided, as shown in fig. 1 to 5, the area of the heat-insulating seat plate 12 is increased, so that the area of the heat-insulating seat plate 12 projected on the horizontal plane accounts for more than 80% of the area of the cover plate 11 projected on the horizontal plane. Furthermore, the projected area of the heat insulation seat plate 12 on the horizontal plane can account for more than 90% of the projected area of the cover plate 11 on the horizontal plane, so that the heat transferred to the cover plate 11 through the heat insulation seat plate 12 is increased, and the generation of condensed water is reduced.

Further, as shown in fig. 2, when the area of the heat-insulating seat plate 12 is increased, the distance L between the heat-insulating seat plate 12 and the front end and the rear end of the cover plate 11 is decreased, and when L is less than or equal to 3mm, an air layer is formed, so that the heat of the heat-insulating seat plate 12 is indirectly transferred to the cover plate 11, the heat obtained by the whole cover plate 11 is more balanced, an obvious cold area cannot occur, and the condensed water is reduced to the maximum extent. Further, L is more than or equal to 0 and less than or equal to 2 mm.

Furthermore, the heat preservation seat plate 12 between the heat preservation seat plate 12 and the cover plate 11 is provided with a fillet, so that the cover plate 11 can not interfere with the heat preservation seat plate 12 when rotating.

Further, a chamfer may be provided on the heat insulating seat plate 12 between the heat insulating seat plate 12 and the cover plate 11, and the cover plate 11 may be rotated without interfering with the seat plate.

This embodiment is through increasing the projected area of heat preservation bedplate 12 on the horizontal plane, and then can furthest with the heat transfer that generates heat 13 and produce for apron 11, reduce the clearance between heat preservation bedplate 12 and the apron 11, and can not appear when the increase of heat preservation bedplate 12 area after, the problem of interfering easily in heat preservation bedplate 12 and the apron 11 assembling process.
