Abstract: A device for removing foreign matter in an ice maker is configured to prevent foreign matter from accumulating on the bottom of a float by changing the structure of the bottom of the float. The device includes a level sensor sensing a water level using a float moving up and down, depending on a height of water supplied in a water tank and a connection pipe forming a channel for water flow between the water pump and the level sensor by being connected to the level sensor, and having an inclined surface inclined downward toward an entrance of the channel under the float.

Abstract: A method and system for cleaning of an ice maker forcing the ice maker to proceed with a cleaning cycle when cleaning of the ice maker is necessary, the method and system including: a cleaning grace period determination step determining, by a controller, whether a cleaning grace period, which allows the cleaning of the ice maker to be deferred, has elapsed when a time for performing a cleaning cycle of the ice maker comes during operation of the ice maker; an ice-separating determination step determining, by the controller, whether ice-separating operation has completed for current ice-making operation when the cleaning grace period is determined to have elapsed; and an operation stop step controlling, by the controller, the cleaning to proceed by stopping actions related to the ice-making and ice-separating operations of the ice maker when the ice-separating operation is completed.

Abstract: Disclosed is a system of controlling an ice maker. The system includes: an ice making part producing ice; a water reservoir provided with a pump, and storing water supplied from outside and providing the water supplied from outside to the ice making part or draining the water outside; and a controller. In particular, when an accumulated number of ice making cycles of the ice making part reaches a predetermined number of ice making cycles, the controller drains the water stored in the water reservoir, and controls a drainage time during which the water is drained on the basis of the predetermined number of ice making cycles, such that the water stored in the water reservoir is drained.

Abstract: Disclosed is a system of controlling an ice maker. The system includes: an ice making part producing ice; an ice reservoir storing the ice; a water reservoir storing water supplied from outside and providing the water to the ice making part or draining the water; and a controller, when a full state of the ice reservoir is sensed after an ice separation process of separating the ice produced in the ice making part is completed, stopping operation of the ice making part and allowing a first drainage of the water stored in the water reservoir to a predetermined water level and a second drainage of the stored water for a predetermined additional drainage time. In particular, the controller controls the additional drainage time desired for the second drainage by comparing an actual drainage time desired for the first drainage with a preset normal time.

Abstract: A system of controlling an ice maker. The system includes: an ice making part producing ice; a water reservoir to store water supplied from outside and provide the water to the ice making part or drain the water; and a controller to control the ice making part to perform an ice separation process, supply the water to the water reservoir during an ice separation time, and drain the water in the water reservoir when an accumulated number of ice making cycles of the ice making part reaches a predetermined number of ice making cycles. In particular, when the accumulated number of ice making cycles reaches the predetermined number of ice making cycles and the water in the water reservoir is drained, the controller increases the ice separation time, drains the water in the water reservoir for the increased ice separation time, and re-supplies the water to the water reservoir after draining the water.
