Abstract

PURPOSE:To prevent erroneous operation such that rice-boiling is started with no pan being set at a predetermined position and so forth by providing a drawer section in which a rice-boiling section is stored, and an incomplete setting detecting means for detecting such a condition that the drawer section is incompletely set. CONSTITUTION:When a quantity of rice to be boiled is determined and inputted, a control section 13 transmits a control signal to a rice bin 3 from which a predetermined quantity of rice is fed into a rice polishing section 5 through each of three rice discharge ports 4. A rice polishing motor in the rice polishing section 5 is driven to remove bran from the rice. Thus polished rice is conveyed through a transfer pipe into a rice boiling section 11. If the rice boiling section 11 including a pan 1, which is store in a drawer section 12 has been pulled forward, an incomplete setting detecting means 11 detects this condition and transmits a control signal to the control section 13 which accordingly stops all operation. With this arrangement, it is possible to prevent a water feed section 30 for feeding water into the pan 1 and a rice transfer section 6 from being operated to feed water and rice unexpectedly. Further, it is possible to prevent rice boiling from being started with no pan 1 being set at a predetermined position.
