2) electromagnetic clutch 217 started below the second screw mandrel 203 makes the second screw mandrel 203 rotate and controls rice-washing device entire lowering, until the rice-discharging port 106 bottom rice washing storehouse 100 is inserted partially in electric cooker body, after simultaneously, roll-over 210 completes with rice, master controller 215a controls electromagnetic clutch 217 and works, 3rd screw mandrel 212 is reversely rotated, middle roll-over 210 moves upward, until the discharging opening 210b of middle roll-over 210 and guide plate 211 another side are connected by through hole 214 to the mouth of pipe of mitron 105, because middle roll-over 210 is obliquely installed, make the rice in roll-over 210 through naturally dropping in rice washing storehouse to mitron 105,
3) start rationing water-adding unit 122 add water to washing in meter chamber 101 and rinse, start the motor controlling agitator and rotate simultaneously, start to enter and wash a meter duty, now the second screw mandrel 203 continues to rotate, when second screw mandrel 203 contacts with the male and fomale(M&F) of the second nut, rice-washing device entirety produces and vibrates, and is beneficial to and strengthens rice washing effect and make the rice washed on meter chamber 101 wall fall to cavity bottom; Start suction pump 123 and discharged the rice washing water washed in meter chamber 101 by drainpipe 104;
4) rice washing terminate after the first screw mandrel 110 start working, plug 107 moves downward to be opened, and starts to throw rice.Now continuing rotation first screw mandrel 110 can make the end 114 of the first screw mandrel 110 thread surface slide along the waveform convex-concave surface of described first nut 111, and then promote rice-washing device overall up-down vibration again, open feed pipe 103 simultaneously and wash meter chamber 101 inwall, be beneficial to and the rice washing meter chamber 101 inwall is rinsed well.
5) start the second screw mandrel 203 and the first screw mandrel 110, close rice-discharging port 106 and make rice-washing device entirety upwards promote simultaneously, this body running of electric cooker, starts to boil meter Cheng Xu.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
