First, as the operation process of the damper 150 when the refrigerator compartment door 6 is opened, when the refrigerator compartment door 6 which seals the refrigerator compartment R of the main body 2 of the refrigerator is opened, the door 6 to be rotated is opened. The rotating member 152 is rotated in the counterclockwise direction with the hinge 45 fixed to both ends of the fixing member 154 as a central axis, and the rotating member by opening the door 6 as described above. When the 152 rotates, as shown in FIG. 8, the space partitioning device installed in the rotating member 152, that is, the first and second partition members 153 and 155, is formed inside the rotating member 152. The compressed air is expanded by the first partition member 153 which is rotated together with the rotating member 152 of the space partitioning device which partitions the filling space A of a predetermined size so that the air is filled by the reaction force. The state before air is compressed by pushing out the 1st partition member 153 which was pressurizing the air While rotating to the filling space (A) of the door 6 is to adjust the rotation speed so that it can be opened slowly.

On the contrary, when the refrigerating compartment door 6 is closed to seal the refrigerating compartment R, the hinges 45 fixed to both ends of the fixing member 154 together with the rotating door 6 are fixed. It rotates in a clockwise direction with the central axis. When the rotating member 152 is rotated by closing the door 6 as described above, as shown in FIG. 9, the space partitioning device installed in the rotating member 152. That is, the rotating member 152 of the space partitioning device which is composed of the first and second partition members 153 and 155 to partition the filling space A of a predetermined size so that air is filled in the rotating member 152. By compressing the air expanded in the filling space (A) by the first partition member 153 rotated with the) can prevent the impact of closing the door 6 and attenuate the closing speed of the door (6) Will be.

In this case, even if the refrigerating compartment door 6 is tightly closed, as the closing speed of the door 6 is controlled by the damper 150, the opposite side freezer compartment door 4 that is closed is not opened and is kept closed. When opening and closing the freezer compartment door 4, the opening and closing speed of the door 4 is also controlled through the damper 150, so that the water in the ice maker 10 installed inside the freezer compartment door 4 is the ice maker. (10) The overflow overflow phenomenon to the outside can also be minimized.

The damper structure of the present invention configured as described above is not only a side-by-side type refrigerator in which the freezer compartment F and the refrigerating compartment R are divided into left and right sides, but also a freezer compartment. Top mount-type refrigerators (F) and refrigerator compartment (R) partitioned up and down, and bottom freezer type (Bottom Freezer), compartments of refrigerator (R) and freezer compartment (F) divided up and down -Type) refrigerators can be applied in advance.

The damper structure for a refrigerator of the present invention includes a damper installed between a hinged refrigerator door and a main body, and a working fluid pressurized by a first partition member of a space compartment device installed in the damper when the damper is opened or closed. The inside of the damper, or while the working fluid (air) is pressed by the first partition member in a predetermined space to prevent the impact of the door closing and attenuating the closing speed of the door by configuring the refrigerator door, When one side of the refrigerating compartment door is closed, there is an excellent effect of preventing the opening of the opposite side of the freezer compartment door closed by the compressed flow of the outside air and the inside of the cold air introduced through the damper.

In addition, the opening and closing of the freezer compartment door also controls the opening and closing speed of the door through the damper, thereby minimizing the overflow of water in the ice maker installed inside the freezer compartment door to the outside of the ice maker.
