Abstract
Icemaker in a refrigerator for making ice automatically is disclosed. The icemaker in includes an ice tray provided to a door on the refrigerator for holding water, an ejector fitted adjacent to the ice tray so as to be rotatable by a motor for ejecting ice from the ice tray, means for detecting a rotation angle of the ejector, and a control part for controlling a rotation direction of the ejector based on information detected at the means.
Claims19
An icemaker in a refrigerator comprising:
- an ice tray provided to a door on the refrigerator for holding water;
- an ejector fitted adjacent to the ice tray so as to be rotatable by a motor for ejecting ice from the ice tray;
- a detector that detects a rotation angle of the ejector;
- the detector including:
- a magnet fitted to a rotating body rotatably interlocked with a shaft of the motor;
- and
- at least two sensors fitted to a plate spaced from each other, the plate being arranged opposite to the rotating body, each sensor senses a magnetic flux when the magnet comes close thereto, to measure a rotation angle of the ejector;
- and
- a control part for controlling a rotation direction of the ejector based on information detected at the detector.

An icemaker in a refrigerator comprising:
- an ice tray provided to a door on the refrigerator for holding water;
- an ejector fitted adjacent to the ice tray so as to be rotatable by a motor for ejecting ice from the ice tray;
- a dropper having a sloped surface covering a part of an upper part of the ice tray, the dropper with no gap through which the ejector passes so that water in the ice tray is prevented from overflowing through the dropper;
- a detector detecting a rotation angle of the ejector;
- and
- a control part for controlling a rotation direction of the ejector based on information detected at the detector.
