A method of controlling an ice maker is provided that minimizes generation of excess water and reduces energy consumption. The method allows for uniform heat to be generated and distributed throughout the ice tray during an ice separation process. Consequently, the ice separating process may be consistently performed irrespective of the shape of the ice tray and its surroundings, thereby minimizing generation of excess water, and reducing energy consumption.

Controlling method of ice maker

An ice making assembly for a refrigerator and a method for controlling the ice making assembly are provided. The ice making assembly and the method of controlling the ice making assembly provides a constant amount of water supply for each ice making cycle regardless of environmental conditions such as the varying water supply pressure of different installation locations. Furthermore, overflowing can be prevented during water supply with the use of a capacitance water level sensor.

Ice making assembly for refrigerator and method for controlling the same

An ice-making device designed to make and separate ice from an ice tray through a simple process is provided. The ice-making device includes an ice tray defining an ice-making space, a freezing core that is partly received in the ice-making space to make ice at an end thereof, a driving unit moving and rotating the freezing core, and a power transmission unit for transferring power from the driving unit to the freezing core. The power transmission unit including a cam unit rotatably connected to the driving unit and a moving member that moves in vertical and rotational direction by a driving force of a motor transferred by the cam unit.

Ice-making device for refrigerator

An ice-making device for a refrigerator, which is designed to separate ice through a simple process is provided. The ice-making device for a refrigerator includes an ice tray defining an ice-making space, an ice core member that is partly received in the ice-making space to make ice at an end thereof, a driving unit moving and rotating at least one of the ice tray and the ice core member, and a power transmission unit for transferring power from the driving unit to the ice core member. The ice on the ice core member starts being separated in a state where the ice is spaced apart from an outer surface of the ice tray.

Ice-making device for refrigerator and method for controlling the same

An icemaker and a refrigerator having an icemaker are discussed. The icemaker has pulse-electrothermal ice release and includes an ice-making tray having several ice forming portions in which water is stored and ice is formed; and a housing surrounding the ice-making tray provided with at least one cold air inlet and/or ice ejection port through which cold air is supplied and ice released along a bent channel. The cold air inlet and/or ice ejection ports are baffled to prevent contact with a user's fingers and thereby reduce the possibility of electric shock.

Pulse electrothermal mold release icemaker with safety baffles for refrigerator

Ice maker including an ice making container () having a plurality of cavities () for forming ice, a heater body () on one side of the ice making container for selective generation of heat, and heating bars () each extended from the heater body to the cavity by a predetermined length with a profile in conformity with a bottom surface profile of the cavity () with a gap to the bottom surface such that the heating bar () is submerged under water in the cavity for causing a temperature gradient during ice making.

Apparatus for ice-making and control method for the same

Ice making assembly for a refrigerator and a method for controlling the ice making assembly. The ice making assembly and method capable of more effectively providing transparent ice. The ice making assembly and method also capable of preventing water overflow.

An ice maker and a controlling method thereof are provided. The system and method may prevent the overflow or splashing of water or thin ice out of an ice tray during the supply of water or when the ice maker is shaken by an external force. The ice maker may include an ice tray, and an ice tray cover that covers an open portion of the ice tray. The cover may include an opening through which water may be supplied to the ice tray, and through which ice may be discharged from the ice tray. The cover may move together with the tray, or may move separately from the tray, to facilitate these supply and discharge processes.

Ice maker and control method of same

An ice tray is provided that prevents the overflow or splashing of water or thin ice out of the ice tray as water is supplied to the ice tray, or when the ice tray is shaken by an external force. The ice tray may include a plurality of receiving portions that receive water for freezing into ice pieces. An overflow preventing portion may extend upward from upper edges of the receiving portions to form a barrier to water flowing out of the ice tray. Alternatively, the receiving parts may be positioned within a corresponding plurality of location parts having water proofing walls extending upward therefrom to inhibit the unintentional flow of water or thin ice out of the receiving portions of the ice tray.

Disclosed is a variable capacity scroll compressor including a stationary scroll member on which a stationary spiral wrap is formed, an orbiting scroll member on which an orbiting spiral wrap is formed, the orbiting scroll member rotating while surface-contacting the stationary scroll, a driving motor, a driving shaft for rotating the orbiting scroll member using power transmitted from the driving motor, a control chamber formed on a predetermined portion of the stationary spiral wrap, a pivotal block disposed in the control chamber, and a controller for controlling a pivotal motion of the pivotal block.

Variable capacity scroll compressor

An apparatus for changing capacity of scroll compressor comprises: a seal member movably installed on one of facing surfaces of a fixed scroll so as to seal a compression space made by the fixed scroll and orbiting scroll; a back pressure passage formed to be communicated from a point, where the seal member is contacted, to an outer circumferential surface of fixed scroll; an exhaust pipe installed on outer circumferential surface of the fixed scroll to be communicated with back pressure passage; and an exhaust pipe opening/closing valve installed on center part of exhaust pipe to open/close the exhaust pipe selectively, and thereby, sealability can be improved and low capacity can be outputted without decelerating orbiting scroll in low capacity operation.
