  • Patent number: 4441016
    Abstract: An electric rice cooker is disclosed which performs auxiliary cooking such as "twice cooking" by changing the operating time of auxiliary cooking in accordance with the actual cooking amount, immediately after the main cooking is completed. The actual temperature of a kettle which contains rice and water and which is detachably mounted in a thermal insulating frame is measured by a thermistor. Upon deenergization of an electric heater after main cooking is completed, the actual kettle temperature decreases. A time interval for the kettle temperature to go from a first temperature at the completion of main cooking to a second temperature is closely related to the actual cooking amount. The auxiliary cooking time interval is determined by a control circuit arranged in a case in accordance with the time interval described above.

  • Patent number: 4421974
    Abstract: An electric rice cooker is disclosed which has a cooking kettle containing rice and water, a thermal insulating frame and an electric heater provided adjacent to the outside surface of the kettle. The electric rice cooker performs auxiliary cooking, such as "twice cooking", for effectively converting beta-starch to alpha-starch after main cooking is completed. The auxiliary cooking operating time is properly determined in accordance with the actual amount to be cooked when every cooking operation is performed. The actual amount to be cooked is detected by a control circuit arranged in a case in accordance with a change in actual kettle temperature measured by a thermistor after a heater is deenergized, that is, in accordance with a peak temperature obtained by "after heat".

  • Patent number: 4418614
    Abstract: A drip mechanism of a coffee extractor has a heater which boils water to be poured on coffee powder and a control switch which controls the ON/OFF operation of the heater. The control device of this drip mechanism has first and second discriminating circuits, so that the ON/OFF operation of the control switch is controlled by an output of a drive circuit controlled by output signals of these discriminating circuits. A predetermined amount of coffee powder is stored in a case. Subsequently, when a regular drip switch and a start switch are depressed, the heater is heated in a first mode so that regular coffee is extracted. When the strong drip switch and the start switch are depressed, the heater is heated in a second mode so that strong coffee is extracted. In order to accomplish this selective operation, a logic circuit is arranged to control the first and second discriminating circuits.
