Description
Technical field
The present invention relates to electric cooker technical field more particularly to a kind of uniform temperature type electric cooker inner container structures.
Background technique
Traditional electric cooker is generally used bottom-heated disk technology, by adding after the heating dish heating of bottom in pot
It cooks the bottom that the heat of hot plate is transmitted to liner again.Since heating dish is only located at electric cooker inner container bottom, heat is concentrated
It is heated at liner at the bottom, inner wall relatively slow, efficiency of cooking is lower, and different parts uneven heating is even in liner, interior when cooking
Portion's uneven heating is even, and the rice finally cooked is located at the hardness of liner different levels, mouthfeel can generate difference；And heat from
When liner at the bottom is transmitted to side wall, many heats can be lost by outer wall.
Such as Chinese patent Authorization Notice No. is CN204500374U, authorized announcement date is on July 29th, 2015, is disclosed
A kind of novel electric cooker inner container, including liner ontology, edge is arranged to wiredrawn edge structure, liner sheet at the upper end opening of liner ontology
