Claims15
A refrigerator comprising:
- a cabinet defining a storage space;
- a barrier that vertically partitions the cabinet to define a refrigerating compartment at an upper side of the barrier and a freezing compartment at a lower side of the barrier;
- at least one refrigerating compartment door provided at a front surface of the refrigerating compartment and rotatably installed at the front surface of the refrigerating compartment to cover at least a portion of the refrigerating compartment by rotation thereof;
- a drawer type door withdrawably disposed on a front surface of the freezing compartment, the drawer type door opening and closing the freezing compartment;
- a lower receiving member disposed inside the freezing compartment and connected to the drawer type door, the lower receiving member being withdrawn together with the drawer type door;
- an upper receiving member withdrawably disposed inside the freezing compartment above the lower receiving member;
- a driving member disposed inside the drawer type door;
- a rotation shaft of the driving member that protrudes outwardly from a back surface of the drawer type door, the rotation shaft being rotated based on power provided by the driving member disposed inside the drawer type door;
- a restraint member disposed on an end of the rotation shaft, the restraint member being rotated together with the rotation shaft when the rotation shaft is rotated and being eccentrically disposed from the rotation shaft in one direction to define a protruding portion of the restraint member, a door frame disposed below the restraint member;
- and
- an avoidance part defined within the door frame,
- wherein the driving member is configured to, based on user selection of the lower receiving member, rotate the rotation shaft to a position in which the protruding portion of the restraint member does not interfere with the upper receiving member, thereby allowing the drawer type door to be withdrawn without the upper receiving member,
- wherein the driving member is configured to, based on user selection of the upper receiving member, rotate the rotation shaft to a position in which the protruding portion of the restraint member restrains the upper receiving member and causes the upper receiving member to be withdrawn with the drawer type door
- wherein the protruding portion of the restraint member is positioned within the avoidance part when the rotation shaft is rotated to the position in which the protruding portion of the restraint member does not interfere with the upper receiving member,
- wherein the rotation shaft protrudes outwardly from the back surface of the drawer type door by a predetermined distance,
- wherein the restraint member is spaced from the back surface of the drawer type door, and
- wherein a bottom part of a front end of the upper receiving member is hooked and restrained between the back surface of the drawer type door and the protruding portion of the restraint member when the rotation shaft is rotated to the position in which the protruding portion of the restraint member restrains the upper receiving member.

A refrigerator comprising:
- a cabinet defining a storage space;
- a drawer type door withdrawably disposed on the cabinet, the drawer type door opening and closing the storage space;
- a lower receiving member disposed inside the storage space, the lower receiving member being withdrawn together with the drawer type door;
- an upper receiving member withdrawably disposed above the lower receiving member;
- a manipulation part disposed on the drawer type door, the manipulation part inputting a withdrawal of the receiving members withdrawn together with the drawer type door wherein the manipulation part comprises:
- a manipulation button for selecting one of the upper receiving member and the lower receiving member, and
- a display on which a selected state of the upper receiving member or the lower receiving member selected by the manipulation button is displayed;
- a restraint unit disposed in the drawer type door, the restraint unit being rotated according to an input state of the manipulation part to selectively restrain the upper receiving member;
- a control part electrically connected to the manipulation part and the restraint unit to control an operation of the restraint unit;
- a freezer compartment door selectively opening and closing by the rotation thereof on the cabinet a door frame disposed below the restraint unit;
- and
- an avoidance part defined within the door frame,
- wherein the restraint unit comprises:
- a driving member disposed inside the drawer type door,
- a rotation shaft of the driving member that protrudes outwardly from a back surface of the drawer type door, the rotation shaft being rotated based on power provided by the driving member disposed inside the drawer type door, and
- a restraint member disposed on an end of the rotation shaft, the restraint member being rotated together with the rotation shaft when the rotation shaft is rotated and being eccentrically disposed from the rotation shaft in one direction to define a protruding portion of the restraint member,
- wherein the protruding portion of the restraint member is positioned within the avoidance part when the rotation shaft is rotated to a position in which the protruding portion of the restraint member does not interfere with the upper receiving member,
- wherein the rotation shaft protrudes outwardly from the back surface of the drawer type door by a predetermined distance,
- wherein the restraint member is spaced from the back surface of the drawer type door,
- wherein a bottom part of a front end of the upper receiving member is hooked and restrained between the back surface of the drawer type door and the protruding portion of the restraint member when the rotation shaft is rotated to a position in which the protruding portion of the restraint member restrains the upper receiving member, and,
- wherein the manipulation part is disposed on a dispenser disposed on the freezer compartment door.
