As shown in FIG. 7, the control unit 250 may control the washing unit driving unit, the slider driving unit, the water supply valve, the drain valve, and the like.

First, when the packaged rice 10 is mounted on the rice inlet 120, the weight of the packaged rice 10 is measured by the weight measuring unit 130 installed in the rice inlet 120. Information on the measured weight is provided to the control unit 250. At this time, the packaged rice 10 is standardized or the weight of the rice inside the rice can be separately calculated by previously measuring the weight for offsetting. The control unit 250 may calculate the amount of the introduced rice as a standard percentage and display it on the display unit 190.

The control unit 250 determines the amount of water to be inputted into which information about the weight is inputted. Thereafter, the water supply valve 170 is opened to supply the set amount of water. At this time, the controller 250 checks whether the rotation rod 152 is in the lowered state, and confirms whether the drain slider 200 is raised. That is, the control unit 250 closes the blocking means to stop the rice insertion when the rotating rod 152 is not lowered or when the drainage slider 200 is not lifted.

The control unit 250 opens the water supply valve 170 to supply water corresponding to the amount of rice supplied during the rice introduction. At this time, the drain valve 180 is brought into the closed state.

The control unit 250 transmits a control signal to the washing unit driving unit 160 so that the rotating rod 152 rotates, thereby washing the rice first. The control unit 250 operates the primary cleaning unit driving unit 160 for a predetermined period of time to rotate the rotation bar 152 periodically.

The control unit 250 stops the cleaning unit driving unit 160 when the primary cleaning is completed and transmits the control signal to the slider driving unit 210 so that the drainage slider 200 is gradually lowered. The control unit 250 opens the drain valve 180 while the drain slider 200 is gradually lowered to drain the water. At this time, the control unit 250 adjusts the flow rate of the drain valve 180 so that the rice flour is discharged through the first drain line 182.

The control unit 250 transmits a control signal to the slider driving unit 210 so that the drain slider 200 moves upward so that the drain slider 200 is in the raised position and opens the water supply valve 170 to supply water again do.

Then, the control unit 250 transmits a control signal to the washing unit driving unit 160 so that the rotating rod 152 rotates, thereby washing the rice secondarily. The control unit 250 operates the secondary cleaning unit driving unit 160 for a predetermined time period so that the rotation bar 152 periodically rotates.

The control unit 250 stops the cleaning unit driving unit 160 when the secondary cleaning is completed and transmits a control signal to the slider driving unit 210 so that the drainage slider 200 is gradually lowered. The control unit 250 opens the drain valve 180 while the drain slider 200 is gradually lowered to drain the water. At this time, the control unit 250 adjusts the flow rate of the drain valve 180 so that rice scum is discharged through the second drain line 184. This way, rice can be recycled.

The control unit 250 sequentially transmits appropriate control signals so that the cleaning of the tertiary or more is performed in the same process as the secondary cleaning.

The control unit 250 transmits a control signal to the cleaning unit driving unit 160 so that the rotation bar 152 rises. At the same time, the water supply valve 170 is opened so that water corresponding to the rice is supplied so that the water required when the rice is cooked is supplied.

As described above, the rice washing apparatus according to the embodiment of the present invention separates and discharges the first washed water and the second washed washed water to make it possible to use the water discharged more than the second order depending on the situation, .

In addition, the amount of rice is calculated by weight, and water is appropriately supplied to the rice so that the convenience of the user is increased, and the amount of water unnecessarily added is controlled to save water.
