Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To cook delicious cooked rice at the time of cooking rice and to open a cap at the time of insulating heat for improving convenience and safety by constituting a pressure relief valve of a heat corresponding member which displace-clog the valve when a temperature within a pot becomes high temp. at the time of cooking rice and opens when a temperature is lower than the temperature at the time of cooking rice during insulating heat. SOLUTION: When the temperature within the pot is raised with the advance of rice cooking and reaches the neighborhood of 70 deg.C, the heat corresponding member 27 gradually displaced with the raising of the temperature raises a following rod 21 with the energizing force of a spring 26 and a valve 23 clogs steam relief holes 18 and 18. This clogging tightly closes the inside of the pot to allow water to rapidly infiltrate into rice grains to reduce time for cooking rice and to soften the rice. Then, about 15 minutes passes after the finish of rice cooking and the temperature within the pot is rapidly lowered to start a heat insulating process keeping about 70 deg.C, the member 27 is returned to press a projecting pin 24 to depress the rod 21 to separate the valve 23 from the holes 18 and 18. Thus, air within the pot is communicated with atmosphere to lower pressure within the pot.
