Title: Rice boiler
Inventor: HATA MASAMI
IPC: A47J27/00
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To boil up rice to be tasty with good flavor without producing steam by controlling heating in such a manner that rice can be boiled with the internal pressure of a rice boiler kept within a designated range. SOLUTION: Detection signals of an inner pot temperature sensor 7, a lid temperature sensor 8 and a pressure sensor 9 are input to a control device 13 disposed on the bottom of a rice boiler main body 1 to form heating control means, and the application of a current to a heater 6 is controlled according to the input signals. In the strong heat control processing, the current application rate to the heater 6 is 100% to raise the internal temperature and increase the pressure. If the detected pressure P of the sensor 9 becomes larger than the preset maximum value Pmax (e.g., 1.2atm), current application to the heater 6 is stopped. On the other hand, if the detected pressure P is not lower than the preset minimum value Pmin(e.g., 1.1atm), the current application stop state is kept, and if becomes lower, current application to the heater 6 is again started.  That is, the internal pressure of a rice boiler is held down below the blowoff pressure, so that steam is not emitted from an internal discharge part 10.
