Electric cooker with multi-point floating type heating disc and heating method of electric cooker

Abstract

The invention discloses an electric cooker with a multi-point floating type heating disc. The electric cooker comprises an outer cover, a pot cover, a heat preservation cover arranged in the outer cover, a ceramic inner pot arranged in the heat preservation cover, a heating assembly arranged between the outer side of the bottom of the ceramic inner pot and the inner side of the bottom of the heat preservation cover, and a central cover. The heating assembly comprises the heating disc and a plurality of electric heating pipes. Floating heating blocks are arranged on the electric heating pipes. Each floating heating block comprises an upper heat transfer section and a lower heat transfer section, wherein a limiting check ring is arranged between the upper heat transfer section and the lower heat transfer section, and the lower heat transfer section is sleeved with a compression spring. A plurality of through holes matched with the upper heat transfer sections are formed in the heating disc. The area of the limiting check rings is larger than the area of the through holes. The bottoms of the compression springs abut against the inner side of the bottom of the heat preservation cover, and the upper ends of the compression springs abut against the limiting check rings. The length of the upper heat transfer sections is larger than the depth of the through holes. The bottoms of the electric heating pipes are exposed out of the heat preservation cover. The electric cooker has the advantages that the ceramic inner pot with the non-wear bottom can be heated more uniformly, heat efficiency is higher, and the structure is simple.

Description

technical field [0001] The invention relates to an electric rice cooker, in particular to an electric rice cooker with a multi-point floating heating plate and a heating method thereof. Background technique [0002] At present, when the heating plate of the electric rice cooker is used for heating the ceramic inner pot, two kinds of ceramic inner pots are used, one is a ceramic inner pot with a ground bottom, and the other is a ceramic inner pot without a ground bottom, and the ceramic inner pot with a ground bottom is bonded to the heating plate It is better, but after the bottom of the ceramic inner pot is ground, the surface glaze layer is damaged and there will be water seepage, and the processing cost is very high. There will be uneven gaps between the bottom of the non-grind inner pot and the bottom of the heating plate, resulting in slow heating and greatly reduced heating energy efficiency. Due to the uneven gap, the bottom of the pot will be heated unevenly, resulti...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the non-uniform heating, low energy efficiency, and water seepage of the ceramic inner pot after the ceramic inner pot is heated by the heating plate of the existing electric rice cooker, the present invention provides a multi-point floating heating block, which can not only solve the problem of non-grinding The bottom ceramic inner pot is heated unevenly and the energy efficiency is low. At the same time, it can solve the problem that the ceramic inner pot can fit well without grinding the bottom, achieve the heating function of the ceramic inner pot, and eliminate the problem of water seepage in the ground ceramic pot. Electric rice cooker with floating heating plate and heating method thereof
