Abstract
A refrigerator includes: a cabinet; an upper door; a lower door that is a drawer type door; a draw-out rail that connects the lower door to a storage space in the cabinet and that guides insertion and withdrawal of the lower door in a front-rear direction; an elevation assembly that is located in the lower door, that elevates an object stored in the lower door in a state in which the lower door is withdrawn, and that elevates the object relative to the lower door; and a door restriction device configured to selectively restrict an opening movement of the upper door based on whether the lower door is opened or closed. The door restriction device is configured to restrict the opening movement of the upper door based on the lower door being opened, and to allow the opening movement of the upper door based on the lower door being closed.
Claims20
A refrigerator comprising:
- a cabinet that defines a storage space;
- an upper door configured to open and close a first portion of the storage space;
- a lower door located vertically below the upper door and configured to open and close a second portion of the storage space, the lower door being configured to insert into and withdraw from the second portion of the storage space;
- a draw-out rail that connects the lower door to the storage space and that is configured to guide insertion and withdrawal of the lower door in a forward direction and a rearward direction;
- an elevation assembly located at the lower door and configured to, in a state in which the lower door is withdrawn from the second portion of the storage space, elevate an object stored in a drawer space defined in the lower door, the elevation assembly being configured to elevate the object relative to a bottom surface of the lower door;
- a partition member that is located between the upper door and the lower door and that extends across a front end of the storage space in a horizontal direction to thereby define the first portion of the storage space and the second portion of the storage space;
- a door detection device configured to detect whether the lower door is opened or closed;
- a door restriction device located at the partition member and configured to selectively restrict an opening movement of the upper door;
- and
- an actuator configured to operate the door restriction device based on detection by the door detection device of whether the lower door is opened or closed.
