Patent number: 10927587Abstract: A refrigerator comprises: a cabinet including a storage compartment, a door opening or closing the storage compartment, a door opening device including a push rod moving from an initial position to a door opening position for opening the door and a motor providing power to the push rod, and a controller controlling the motor. The controller allows the motor to rotate at a first opening speed for opening the door of the refrigerator. The controller changes a rotation speed of the motor to a second opening speed lower than the first opening speed before the push rod contacts the door of the refrigerator or the cabinet.Type: GrantFiled: November 27, 2018Date of Patent: February 23, 2021Assignee: LG Electronics Inc.Inventors: Heejun Lee, Dongjeong Kim, Seungyoon Cho
