The rice in the rice washing cylinder 38 is supplied by 60 to wash the rice. This rice washing is to wash away rice bran adhering to the surface of the rice that has been sharpened by the rice polishing section 48, and the predetermined amount of washing water supplied in the rice washing cylinder 38 does not overflow from the rice washing cylinder 38. It flows out from the drain pipe 42 while accumulating in the. After that, the rice in the rice washing cylinder 38 drained by the outflow of the rice washing water falls from the rice washing cylinder 38 into the rice cooking pot 32 by pressing the opening / closing valve 39 by the rice washing actuator 40. When this series of operations is completed, the measuring actuator 45 is actuated again to measure 0.5 unit, and the above operation is repeated. In other words, this series of operations is the desired amount of rice cooked
Repeat 0.5 times to complete washing.

Then, in accordance with the completion of this rice washing, water is again supplied to the water tank 57 via the tank water supply valve 61, and a predetermined cooking water according to the desired rice cooking amount is measured in the same manner as the measurement of the washing water.
Thereafter, this rice cooking water is supplied into the rice washing cylinder 38 by the water supply pump 60 in the same manner as the rice washing water. At this time, in the rice washing section 37, the opening / closing valve 39 is pushed down by the rice washing actuator 40 and the rice washing cylinder
When the water is disengaged from 38, the water shutoff valve 41 is closed, and the supplied cooking water is reliably sent to the rice cooking pot 32 without flowing out from the drain pipe 42. When the water supply for cooking water is completed, the rice cooking section
In 31, the electricity is started to the rice cooking heater 33 and the pan sensor 35 controls the rice cooker to a predetermined temperature to proceed with the rice cooking.

As described above, according to this embodiment, the rice weighing chamber 47 of the rice weighing unit is used.
The volume of the rice is set to 0.5 go, and the rice of 0.5 go is dropped to the rice polishing section 48 by one operation of the weighing actuator 45.
While polishing the rice in 8, the rice is sequentially conveyed to the rice washing room 37 through the rice conveying section 52, and then the rice washing section 37 supplies the washing water in synchronism with the conveyance of the rice of 0.5 unit, and further At the end, the washing water is drained and dropped and conveyed to the rice cooker 32, and this series of operations is repeated for the desired amount of rice cooked / 0.5 go to complete the transfer of rice that has been washed to the rice cooker 32. After that, while washing away the washed rice remaining on the inner surface of the rice-washing cylinder 38, the rice-cooking water is sent to the rice-cooking pot 32 to start the rice-cooking. It can be implemented. In addition, even though the rice-washing unit was dedicated to the conventional rice-cooking pan, it washes 0.5 rice each, and its size was reduced. It is simple and as a result it is easy to use. Furthermore, by setting the volume of the rice measuring chamber 47 of the rice measuring unit to 0.5 go, the rice cooking amount that can be initially set can be selected in steps of 0.5 go from the maximum rice cooking amount to the minimum rice cooking amount. Is.

In this embodiment, the volume of the rice weighing chamber 47 of the rice weighing unit is set to 0.5.
However, it is needless to say that this one-time rice measurement should be 1 / integer of the minimum selectable difference in the amount of cooked rice initially set.

Further, as the rice washing means, in the present embodiment, the description was made by flushing with water after the rice polishing, but the design is not limited to this configuration, and the design can be changed appropriately, and the point is to divide it into multiple times according to the desired amount of cooked rice. Anything can be used as long as it measures rice, rinses rice, and conveys it to a rice cooker, and there is no difference in its action and effect.

Further, the description has been given by starting the next operation after the series of operations from the rice weighing to the rice washing in each time is completed, but it is of course possible to overlap the operations of each time to shorten the time.
