Electric cooker

Abstract

The invention provides an electric cooker capable of relieving the burden of user and more effectively depressing the decay of rice and deterioration of edible flavour induced by heat preservation. The electric cooker comprises boiler holding rice inside the electric cooker body; cover easily openned and closed for covering the peristome of upside of the cooker; heating arrangement for heating the pan bottom; cooker temperature test sensor for detecting temperature; heat control section for controlling the heating action of heating arrangement of the pan bottom; cook information input part for inputting the cook information related with cooking rice; automatic selection part of thermal insulation mode for automatically selecting the corresponding thermal insulation mode from many thermal insulation modes based on the cook information input by cook information input part before cooking; holding temperature control section for controlling temperature, based on thermal insulation mode selected by the automatic selection part of thermal insulation mode and controlling the heat control section by temperature detected by cooker temperature test sensor.

Description

technical field [0001] The invention relates to an electric rice cooker with heat preservation function. Background technique [0002] At present, in this electric rice cooker, the cooked rice should be kept warm at a certain temperature. For example, since rice rots when the holding temperature is low, it is set in the range of about 70° C. to 74° C. to prevent the rot of the rice, maintain the warmth of the rice, and reduce the deterioration of the eating taste. [0003] However, in the electric rice cooker of the above-mentioned structure, since the heat preservation temperature is a relatively high temperature, the rice will turn yellow (brown), or emit a unique odor, or become sticky and elastic, etc. Food taste and physical properties are reduced. [0004] Therefore, Patent Document 1 (Japanese Patent No. 2814915) discloses a technology that has a normal holding temperature (for example, a temperature in the range of 70° C. to 74° C.) and a high temperature holding t...

Problems solved by technology

[0007] However, in the techniques of Patent Documents 1 and 2, since the user has to select the keep warm mode by himself, the user needs to accurately grasp the performance of the cooked rice when keeping warm, thus causing an excessive burden on the user.
