[0073] An electric rice cooker according to a second embodiment of the present invention will be described with reference to FIG. 5 . Fig. 5 is a top view of the operation panel of the electric rice cooker according to the second embodiment of the present invention. The electric rice cooker of the second embodiment of the present invention is different from the electric rice cooker of the first embodiment in that it further has a pre-immersion input button 62f. The other points are the same as those of the first embodiment, so repeated descriptions will be omitted.

[0074] As shown in FIG. 5 , the preliminary immersion input button 62 f is provided on a part of the information input part 62 . Here, preliminarily soaking in water means that the rice is preliminarily soaked in water after the rice and water are added to the pot 2 until the rice cooking is started. In the second embodiment of the present invention, the user refers to the case where the rice absorbs water for 1...

[0080] An electric rice cooker according to a third embodiment of the present invention will be described with reference to FIG. 6 and FIG. 7 . FIG. 6 is a block diagram showing the structure related to the control unit of the rice cooker according to the third embodiment of the present invention, and FIG. 7 is a flow chart showing the flow of keeping warm mode selection of the rice cooker according to the third embodiment of the present invention. The rice cooker according to the third embodiment of the present invention is different from the rice cooker according to the second embodiment in that it further includes a cooked rice amount determination unit 65 . The other points are the same as those of the second embodiment, so repeated descriptions are omitted.

[0081] The amount of cooked rice determination unit 65 is configured to determine the amount of cooked rice based on the change per unit time of the pot temperature detected from the pot bottom temperature sensor 5 d...

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...
