Abstract

PURPOSE:To adjust water quantity always accurately by calculating the flow rate per a unit time with a control device based on the number of rotation per the unit time at a flow rate sensor of a water feed pipe and opening a closing device of the water feed pipe until the integrated flow quantity reaches a designated value. CONSTITUTION:A rice cooker is set under a rice washer 3 to wash the polished rice supplied from a rice bin, to adjust water, and to perform impregnation. A closing device 36a (and 36b), a flow rate sensor 34 and an operation device are set on a water feed pipe 35. A control device 20 of the closing device 36a is set in the rice washing and cooking device. The control device 20 accumulates the flow rates per a very small unit time based on the number of the rotation pulse of the flow rate sensor 34 to rotate per a unit time or the time required to count the designated pulse number by the flow rate sensor 34. The control device 20 controls the water feed by opening the closing device 36a until the accumulated value reaches a designated value. Thus, the water adjustment is accurately performed.
