Title: Jar rice-cooker
Inventor: TOMITA KAZUNORI
IPC: A47J27/00
Filed: 1987-12-24
Abstract: PURPOSE: To make a valve of a steam port securely operate at a prescribed temperature by attaching the valve inside a steam port on the outer lid of a thermal rice cooker to be engaged with a tapered part of the steam port, and attaching a coil spring and a shape memory alloy coil to open/close the steam port by energizing the valve in opposite directions each other. CONSTITUTION: When water and rice are put in a pot 1 of this thermal rice cooker and electricity is turned on, a valve 12 is pressed on a tapered part 11a of a steam port 11 by the energizing force of a coil spring 13, and the steam port 11 is closed. When the pot 1 is heated by a heater 4 and the temperature inside the pot rises, a shape memory alloy coil 14, detecting the temperature, tries to restore its original length, and pushes up the valve 12 resisting the energizing force of the coil spring 13. Thus, a gap is formed between the valve 12 and the tapered part 11a of the steam port 11, and steam is let out from the gap.  When cooking is finished and the temperature inside the pot drops to keep the rice warm, the energizing force of the shape memory alloy coil 14 becomes weak, and the valve 12 is pressed on the tapered part 11a of the steam port 11 again by the energizing force of the coil spring 13, thereby the gap is closed. By this way, the inside of the thermal rice cooker is sealed when the rice is kept warm.
