The refrigerator also includes a cooling device configured to cool the storage room, a first storage area disposed inside the storage room, and a door mounted to the main body. The refrigerator further includes a second storage unit disposed at the door and a third storage unit configured to move between an inserted position inside the storage room and an extracted position in which at least a portion of the third storage unit is extracted outside of the storage room. ## Claims ### Claim 1 A refrigerator, comprising: a main body; a storage room defined in the main body; a cooling device configured to cool the storage room; a first storage area disposed inside the storage room; a door mounted to the main body and configured to open and close the storage room; a second storage unit disposed at the door; and a third storage unit configured to move between an inserted position inside the storage room and an extracted position in which at least a portion of the third storage unit is extracted outside of the storage room, wherein, in the extracted position, the portion of the third storage unit extracted outside of the storage room defines an obtuse inclination angle with respect to a portion of a front surface of the storage room that extends from the third storage unit toward a wall of the main body to which the door is mounted. ### Claim 2 (depends on 1) The refrigerator of claim 1, wherein a width of the third storage unit is smaller than a width of the door. ### Claim 3 (depends on 1) The refrigerator of claim 1, wherein, when the third storage is in the inserted position inside the storage room and the door is closed, the third storage unit is positioned adjacent to a rear surface of the door. ### Claim 4 (depends on 1) The refrigerator of claim 1, wherein, when the third storage unit is in the inserted position inside the storage room and the door is closed, the third storage unit is positioned adjacent to a front of the first storage area, and the second storage unit is positioned adjacent to a front of the third storage unit. ### Claim 5 (depends on 1) The refrigerator of claim 1, wherein, when the door is opened and the third storage unit is in the extracted position, the third storage unit protrudes from the storage room in a direction opposite to the door. ### Claim 6 (depends on 1) The refrigerator of claim 1, wherein, when the door is opened and the third storage unit is in the extracted position, at least a portion of the third storage unit is opposite to the second storage unit in a lateral direction. ### Claim 7 (depends on 1) The refrigerator of claim 1, wherein the third storage unit includes a plurality of keeping portions arranged to be vertically spaced apart from one another. ### Claim 8 (depends on 7) The refrigerator of claim 7, wherein the third storage unit has one or more openings between the plurality of keeping portions, and the one or more openings are open in a front-back direction when the third storage unit is in the inserted position inside the storage room such that the first storage area is accessible through the one or more openings. ### Claim 9 (depends on 7) The refrigerator of claim 7, wherein at least one of the plurality of keeping portions includes a support, and a holder configured to restrict products supported by the support from being overturned. ### Claim 10 (depends on 1) The refrigerator of claim 1, wherein a rotational center of the third storage unit is positioned inside the storage room. ### Claim 11 (depends on 1) The refrigerator of claim 1, wherein the third storage unit includes a rotary member rotatably connected to the main body, and a frame configured to slide along the rotary member and configured to store products therein. ### Claim 12 (depends on 11) The refrigerator of claim 11, wherein, when the rotary member is rotated inside the storage room, a lateral width of the rotary member is shorter than that between left and right walls of the storage room. ### Claim 13 (depends on 11) The refrigerator of claim 11, wherein a rotational axis of the rotary member is mounted at a wall of the storage room that is closest to a rotational axis of the door. ### Claim 14 (depends on 1) The refrigerator of claim 1, wherein the third storage unit includes a frame configured to store products therein, a first link rotatably connected to each of the main body and the frame, and a second link spaced apart from the first link and rotatably connected to each of the main body and the frame. ### Claim 15 (depends on 14) The refrigerator of claim 14, wherein the first link is rotatably connected to a rear wall of the storage room and an end of the frame, and the second link is rotatably connected to a side wall of the storage room and a rear end of the frame. ### Claim 16 (depends on 14) The refrigerator of claim 14, wherein the first link is longer than the second link. ### Claim 17 (depends on 14) The refrigerator of claim 14, wherein each of the first and second links is a bent link. ### Claim 18 (depends on 1) The refrigerator of claim 1, wherein the third storage unit includes a frame rotatably mounted in an opposite direction to a rotational direction of the door and configured to store products therein. ### Claim 19 A refrigerator, comprising: a main body; a storage room defined in the main body; a cooling device configured to cool the storage room; a first storage area disposed inside the storage room; a door rotatably mounted at a side of the main body and configured to open and close the storage room; a second storage unit disposed at the door; and a third storage unit configured to move between an inserted position inside of the storage room and an extracted position in which at least a portion of the third storage unit is extracted outside of the storage room, wherein, when the third storage unit is in the inserted position inside the storage room and the door is closed, the third storage is positioned at a rear of the door, and wherein, when the door is opened and the third storage unit is in the extracted position, the third storage unit protrudes from the storage room in an opposite direction to the door at an obtuse inclination angle with respect to a front surface of the storage room that extends from the third storage unit toward the side of the main body to which the door is mounted. ### Claim 20 (depends on 19) The refrigerator of claim 19, wherein, when the door is open and the third storage unit is in the extracted position, the second storage unit is positioned at a first side of a front of the storage room, and the third storage unit is positioned at a second side of the front of the storage room that is opposite of the first side of the front of the storage room.
