Patent number: 10829881Abstract: The present disclosure provides a door lock device for releasably locking a door of a washing machine. The door lock device has first to third latches, and a drive motor and a latch drive mechanism for moving the third latch. The first latch releasably locks the door of the washing machine and is movable in frontward and rearward directions. The movement of the first latch is changed at a change position. The first latch is always biased frontward by a spring. The second latch releasably locks the first latch, which locks the door of the washing machine, at a door locking position. The third latch is moved in a direction perpendicular to the movement direction of the first latch. The third latch restricts the first latch at the door locking position, or unlocks the first latch after pushing the first latch from the door locking position against the spring.Type: GrantFiled: November 21, 2016Date of Patent: November 10, 2020Assignee: SCD CO., LTD.Inventor: Jae Hyoung Choi

Patent number: 10139146Abstract: An apparatus and a method for driving an icemaker for making ice cubes in a refrigerator. An ice-full state is sensed in such a way as to rotate an ejector and a cam gear in a reverse direction (opposite to an ice-ejecting direction), thereby preventing interference with the ice cubes present in the icemaker and thus enabling the ice-full state to be accurately sensed. A first torsion spring is mounted to an intermediate gear with a small rotation angle ratio to allow only a minimum amount of torque to be transferred to other components such as an ice-detecting lever, thereby increasing the durability of the components and providing a precise rotation force. The axial center of rotation of a second torsion spring is defined at a position that faces the other end (the revolving end) of the ice-detecting lever, to allow a minimum moment to be substantially constantly applied.Type: GrantFiled: May 10, 2013Date of Patent: November 27, 2018Assignee: SCD CO., LTD.Inventor: Jin Sung Park

Patent number: 9784491Abstract: Provided is a driving device for an automatic ice-making machine, the driving device including: a cam gear that rotates a tray; and an operating lever that organically operates along a cam plane for an ice-cube quantity detecting arm formed at the cam gear and allows the ice-cube quantity detecting arm to rotate downward into an ice-cube storage bin, wherein a cam groove for the ice-cube quantity detecting arm is formed in the cam plane for the ice-cube quantity detecting arm of the cam gear and allows the operating level to descend so that the ice-cube quantity detecting arm rotates downward into the ice-cube storage bin, and a protrusion is formed between the cam plane for the ice-cube quantity detecting arm and the cam groove for the ice-cube quantity detecting arm and allows the operating lever to ascend so that the ice-cube quantity detecting arm that rotates downward into the ice-cube storage bin rotates upward.Type: GrantFiled: March 8, 2013Date of Patent: October 10, 2017Assignee: SCD CO., LTD.Inventor: Jae Hyeong Choi

Publication number: 20150362241Abstract: A driving device of an icemaker for refrigerator may include: a case 100; a driving unit 110 mounted in the case 100, including a gear unit 104 having a magnet M formed thereon and a motor M connected to the gear unit 104, and configured to drive an icemaker of a refrigerator; and a housing 100b into which the case 100 including the driving unit 110 is detachably inserted. Since the driving device of the icemaker is assembled as a module, the assembly time and speed may be improved to increase workability. Simultaneously, a low-voltage DC step motor may be used to reduce a risk of fire and electric shock, thereby increasing stability. Furthermore, since the magnet M is rotated around the center axis of the gear unit, a rotation signal may be sensed and outputted through a constant magnetic force. Thus, the merchantable quality of the driving device may be maximized.Type: ApplicationFiled: March 7, 2013Publication date: December 17, 2015Applicant: SCD CO., LTD.Inventor: Jin Ho LEE
