Abstract

A method for controlling a garbage disposer that includes a crushing unit, a housing that includes an inlet port and an outlet port, a storage body, a communication hole, and an agitation unit is disclosed. The method includes the actions of connecting the communication hole with the inlet port by rotating the storage body. The method further includes opening the communication hole by rotating the agitation unit. The method further includes crushing, by the crushing unit, garbage. The method further includes supplying garbage to the inlet port. The method further includes closing the communication hole by rotating the agitation unit. The method further includes dehydrating garbage stored in the storage body by rotating the agitation unit and the storage body at a first rotation speed while maintaining the communication hole in a closed state.

First claim

What is claimed is:

1. A method of controlling a garbage disposer that includes a crushing unit that is configured to crush garbage, a housing that includes an inlet port that is configured to receive garbage and an outlet port that is configured to discharge garbage, a storage body that is rotatably connected to the housing and that defines a space for storing garbage, a communication hole that is located at the storage body and that is configured to connect to the inlet port or the outlet port based on an orientation of the storage body, and an agitation unit that is rotatably connected to the storage body and that is configured to open and close the communication hole, the method comprising:
connecting the communication hole with the inlet port by rotating the storage body;
opening the communication hole by rotating the agitation unit;
crushing, by the crushing unit, garbage;
supplying garbage to the inlet port;
closing the communication hole by rotating the agitation unit; and
dehydrating garbage stored in the storage body by rotating the agitation unit and the storage body at a first rotation speed while maintaining the communication hole in a closed state.

2. The method according to claim 1 , wherein crushing garbage includes spraying water toward a blade that is configured to crush garbage.

3. The method according to claim 2 , wherein spraying water toward the blade comprises spraying water through a first nozzle and a second nozzle.

4. The method according to claim 3 , wherein water sprayed from the first nozzle sprays in a first direction and water sprayed from the second nozzle sprays in a second direction that is perpendicular to the first direction.

5. The method according to claim 1 , further comprising:
maintaining the communication hole in a closed state by rotating the agitation unit and the storage body at a second rotation speed that is lower than the first rotation speed;
detecting an unbalance of garbage stored in the storage body by detecting a fluctuation range of an rotation speed of the storage body; and
repeating the dehydration of garbage based on the fluctuation range of the rotation speed of the storage body being less than or equal to a predetermined reference value.

6. The method according to claim 1 , further comprising:
maintaining the communication hole in a closed state by rotating the agitation unit and the storage body at a second rotation speed that is lower than the first rotation speed;
detecting an unbalance of garbage stored in the storage body by detecting a fluctuation range of an rotation speed of the storage body; and
supplying water to the housing and rotating the agitation unit based on the fluctuation range of the rotation speed of the storage body being greater than a predetermined reference value.

7. The method according to claim 6 , further comprising:
connecting the communication hole to the inlet port by rotating the storage body based on the fluctuation range of the rotation speed of the storage body being greater than the predetermined reference value; and
agitating garbage stored in the storage body by rotating only the agitation unit.

8. The method according to claim 5 , further comprising:
determining an amount of garbage in the storage body by measuring a period of time from when power supplied to the driving unit that is configured to rotate the storage body during maintenance of the communication hole in a closed state is interrupted until rotation of the storage body is halted; and
increasing, proportional to the amount of garbage in the storage body, an execution time for the dehydration of garbage.

9. The method according to claim 5 , further comprising:
determining an amount of garbage stored in the storage body by measuring a period of time from when power supplied to the driving unit that is configured to rotate the storage body during maintenance of the communication hole in a closed state is interrupted until rotation of the storage body is halted; and
repeating the dehydration of garbage stored in the storage body by rotating the agitation unit and the storage body at a rotation speed that is greater than the first rotation speed by a rotation speed that is proportional to the amount of garbage stored in the storage body.

10. The method according to claim 1 , further comprising:
maintaining the communication hole in a closed state by rotating the agitation unit and the storage body at a second rotation speed that is less than the first rotation speed and supplying electric power to the driving unit;
determining an amount of garbage stored in the storage body by measuring a period of time from when power supplied to the driving unit is interrupted until rotation of the storage body is halted; and
increasing, proportional to the amount of garbage in the storage body, an execution time for the dehydration of garbage.

11. The method according to claim 1 , further comprising:
opening the outlet port by opening a housing door located at the housing;
after completion of the dehydration of garbage, connecting the communication hole with the outlet port by rotating the storage body and the agitation unit; and
discharging garbage stored in the storage body by rotating the agitation unit.

12. The method according to claim 11 , wherein the opening of the outlet port and the connection of the communication hole with the outlet port occur simultaneously.

13. The method according to claim 1 , further comprising:
drying garbage stored in the storage body by supplying hot air to the housing.

14. The method according to claim 13 , wherein the drying of garbage occurs after dehydration of garbage.

15. The method according to claim 13 , wherein the drying of garbage comprises rotating only the agitation unit without rotating the storage body.

16. The method according to claim 15 , further comprising:
periodically repeating the rotation of only the agitation unit without rotation of the storage body while supplying hot air to the housing.

17. The method according to claim 15 , wherein the drying of garbage comprises:
connecting the communication hole with the inlet port by rotating the storage body; and
agitating garbage stored in the storage body by rotating only the agitation unit.

18. The method according to claim 13 , further comprising:
after the drying of garbage, connecting the communication hole with the outlet port by rotating the storage body and the agitation unit;
opening the outlet port by opening a housing door located at the housing; and
discharging garbage stored in the storage body by rotating the agitation unit.

19. The method according to claim 18 , wherein the opening of the outlet port and the connection of the communication hole occur simultaneously.

20. The method according to claim 18 , wherein discharging garbage stored in the storage body comprises discharging garbage into a drawer that is located below the housing.
