The method further includes the action of rinsing the ground food waste. The method further includes the action of discharging wash water. The method further includes the action of drying the ground food waste. The method further includes the action of discharging the dried ground food waste.

First claim

What is claimed is:

1. A control method of a food waste treatment apparatus, the control method comprising:
connecting a discharge side of a grinder with a communication hole of a dehydrator, the communication hole being configured to receive food waste from the grinder;
receiving, by the grinder, the food waste;
grinding the food waste;
receiving, by the dehydrator, the ground food waste;
supplying a predetermined amount of wash water to a housing that includes the dehydrator;
rinsing the ground food waste by moving wash water within the housing;
discharging wash water by rotating the dehydrator and, simultaneously, opening a discharge duct;
drying the ground food waste by rotating an agitator that is located in the dehydrator and, simultaneously, supplying dry air; and
discharging the dried ground food waste by (i) connecting an outlet port of the housing with a communication portion of the dehydrator and (ii) rotating the agitator.

2. The control method according to claim 1 , wherein supplying the predetermined amount of wash water to the housing includes supplying wash water through a first nozzle of the grinder or a second nozzle of the housing.

3. The control method according to claim 1 , wherein rinsing the ground food waste includes simultaneously rotating the agitator and the dehydrator.

4. The control method according to claim 3 , wherein the agitator includes a door blade configured to close the communication hole of the dehydrator.

5. The control method according to claim 1 , wherein rinsing the ground food waste includes rotating the agitator and preventing the dehydrator from rotating.

6. The control method according to claim 1 , wherein discharging wash water by rotating the dehydrator and, simultaneously, opening the discharge duct includes closing a door blade of the agitator by rotating the dehydrator and the agitator, wherein closing the door blade closes the communication hole of the dehydrator.

7. The control method according to claim 1 , further comprising washing the housing and the dehydrator after discharging the dried ground food waste.

8. The control method according to claim 7 , wherein washing the housing and the dehydrator includes:
supplying additional wash water into the housing;
washing the housing and the dehydrator by moving additional wash water; and
draining additional wash water.

9. The control method according to claim 8 , wherein supplying the additional wash water includes supplying additional wash water through a first nozzle of the grinder or a second nozzle of the housing.

10. The control method according to claim 8 , wherein washing the housing and the dehydrator includes rotating the agitator and preventing the dehydrator from rotating.

11. The control method according to claim 10 , wherein the communication hole of the dehydrator is connected with the outlet port of the housing.

12. The control method according to claim 11 , wherein draining additional wash water includes rotating the agitator and, simultaneously, opening the discharge duct of the housing.

13. The control method according to claim 8 , wherein washing the housing and the dehydrator includes simultaneously rotating both the agitator and the dehydrator.

14. The control method according to claim 13 , wherein draining additional wash water includes (i) rotating the agitator and the dehydrator and (ii) simultaneously, opening the discharge duct of the housing.
