Abstract
Disclosed is a rice cooker comprising a pot for containing rice and water, a heater provided at the bottom of the pot for heating the pot, a sensor for sensing temperature of the pot to produce a detecting signal when the temperature of the pot reaches a predetermined value, and a drive circuit which responds to the detecting signal from the sensor to stop the heating of the heater. The drive circuit in the cooker, after the operation start, heats the pot to about 40.degree. C. by the heater for rice immersion, and after keeping the pot warmth constant for a given period, drives the heater at the rated calorific value for rice cooking.
Claims4
An electric rice cooker comprising:
- a pot for containing rice and water;
- a lid removably covering the top of said pot;
- means for heating said pot;
- thermally insulating frame means for supporting and enclosing said pot and said heating means;
- means for detecting temperature of said pot to produce a detecting signal when the temperature of said pot reaches a predetermined value;
- timer means for producing a first timing signal during a first predetermined period from the start of a rice cooking operation and then a second timing signal during a second predetermined period;
- and
- drive means which responds to said first timing signal to drive said heater so as to provide a rated caloric value, to drive said heating means to provide a caloric value smaller than said rated caloric value in response to said second timing signal, and subsequently to drive said heating means so as to provide the rated caloric value until said detecting means produces the detecting signal.
