<p>PURPOSE: A device is provided to considerably reduce an operational force required in opening a door against the attraction of a magnet gasket, to improve the sureness and reliability in the door opening operation, and to reduce the noise level at the same time. CONSTITUTION: A receiving piece(102c) is provided on a door(102a) for a refrigerator. An electrically-driven door opening unit(109) including an electromagnetic solenoid having a push-rod(115) to press the receiving piece(102c) is provided on a ceiling part of a refrigerator body(101). The electromagnetic solenoid comprises a cylindrical coil unit(112) including a frame-like yoke assembly(113, a plunger(114) with the coil unit(112) penetrated in the axial direction, a returning spring(125), etc., and the push-rod(115) is concentrically connected to the plunger(114). When the door(102a) is closed, a tip part of the push rod(115) abuts on the receiving piece(102c) by the spring force of a pressing spring(127), and when the coil unit(112) is energized, the plunger(114) is moved in the axial direction, and the door(102a) is pressed and opened by the push-rod(115).</p> |
