When the door of the refrigerator is opened, the storage of the storage room is positioned inside the storage room, and the door storage is moved to the outside of the storage room so as to be viewed together with the storage of the storage room from the outside.
A user can keep storage products in the storage of the storage room and the door storage according to the sizes or kinds of storage products.
SUMMARY
In one aspect, a refrigerator includes a main body, a storage room defined in the main body, and a cooling device configured to cool the storage room. The refrigerator also includes a first storage area disposed inside the storage room and a door mounted to the main body and configured to open and close the storage room. 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. 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.
Implementations may include one or more of the following features. For example, a width of the third storage unit may be smaller than a width of the door. When the third storage is in the inserted position inside the storage room and the door is closed, the third storage unit may be positioned adjacent to a rear surface of the door. When the third storage unit is in the inserted position inside the storage room and the door is closed, the third storage unit may be positioned adjacent to a front of the first storage area and the second storage unit may be positioned adjacent to a front of the third storage unit.
When the door is opened and the third storage unit is in the extracted position, the third storage unit may protrude from the storage room in a direction opposite to the door. When the door is opened and the third storage unit is in the extracted position, at least a portion of the third storage unit may be opposite to the second storage unit in a lateral direction. A rotational center of the third storage unit may be positioned inside the storage room. The third storage unit may include a frame rotatably mounted in an opposite direction to a rotational direction of the door and configured to store products therein.
In some implementations, the third storage unit may include a plurality of keeping portions arranged to be vertically spaced apart from one another. In these implementations, the third storage unit may have one or more openings between the plurality of keeping portions and the one or more openings may be 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. Further, in these implementations, at least one of the plurality of keeping portions may include a support, and a holder configured to restrict products supported by the support from being overturned.
In some examples, the third storage unit may include 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. In these examples, when the rotary member is rotated inside the storage room, a lateral width of the rotary member may be shorter than that between left and right walls of the storage room. Also, in these examples, a rotational axis of the rotary member may be mounted at a wall of the storage room that is closest to a rotational axis of the door.
In some implementations, the third storage unit may include 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. In these implementations, the first link may be rotatably connected to a rear wall of the storage room and an end of the frame and the second link may be rotatably connected to a side wall of the storage room and a rear end of the frame. Further, in these implementations, the first link may be longer than the second link and each of the first and second links may be a bent link.
In another aspect, a refrigerator includes a main body, a storage room defined in the main body, and a cooling device configured to cool the storage room. The refrigerator also includes a first storage area disposed inside the storage room and a door rotatably mounted at a side of the main body and configured to open and close the storage room. 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 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. 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. 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.
Implementations may include one or more of the following features. For example, when the door is open and the third storage unit is in the extracted position, the second storage unit may be positioned at a first side of a front of the storage room and the third storage unit may be 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.

The cooling device 6 can include a condenser fan allowing air from the outside of the refrigerator to be sent to the condenser. The air sent to the condenser by the condenser fan can be heat-exchanged with the refrigerant and then exhausted to the outside of the refrigerator.
The first storage 10 can be mounted to be positioned inside the storage room 2. The first storage 10 can be a storage of the storage room 2, in which storage products are kept in a state in which the first storage 10 is positioned inside the storage room 2. The first storage 10 can have a front-end 12 positioned inside the storage room 2. The first storage 10 can have a lateral width with which the third storage 40 can be inserted into the storage room 2 in the state in which the first storage 10 is positioned inside the storage room 2. When the third storage 40 is inserted into the storage room 2, and the door 20 is closed, the interval D1 between the front-end 12 of the first storage 10 and a rear-end 32 of the second storage 30 can be formed to have an interval greater than the lateral width D2 of the third storage 40. The first storage 10 can include one or more shelves 11, 12 and 13 mounted in the storage room 2. The one or more shelves 11, 12 and 13 may be arranged to be spaced apart from one another. The one or more shelves 11, 12 and 13 can partition the inside of the storage room 2 into a plurality of storage spaces. The one or more shelves 11, 12 and 13 can be mounted so that their positions are fixed inside the storage room 2, or can be mounted so that their heights are adjustable.
The door 20 can be slid or rotated to open/close the storage room 2. When being rotated to open/close the storage room 2, the door 20 can be mounted to the main body 4 so as to be rotated about one of left and right sides thereof. One of the left and right sides of the door 20 can be rotatably mounted to the main body 4 through a hinge member 22. The door 20 can be adhered closely to a front surface 5 of the main body 4 when the storage room 2 is closed. When being opened, the door 20 can be rotated to have an obtuse inclination angle θ1 with the front surface 3 of the storage room 2.
The second storage 30 can be moved by the door 20. The second storage 30 can be a door storage moved from the internal position of the storage room 2 to the external position of the storage room 2 when the door 20 is opened. When the door 20 is closed, at least a portion of the second storage 30 can be positioned inside the storage room 2. When the door 20 is opened, the entire second storage 30 can be positioned outside the storage room 2. When the door 20 is closed, the second storage 30 can be disposed on the surface of the door 20, which faces the storage room 2. The second storage 30 can be mounted to protrude from the rear surface of the door 20. The second storage 30 can be inserted inside the storage room 2 in a state in which the front-end of the second storage 30 is fixed to the door 20 when the door 20 is closed. The second storage 30 can include one or more baskets 31, 32 and 33 mounted to the rear surface of the door 20. The one or more baskets 31, 32 and 33 may be mounted to be spaced apart from one another. Each of the one or more baskets 31, 32 and 33 can include a box body having an opened upper surface. The one or more baskets 31, 32 and 33 can be mounted so that their positions are fixed to the door 20, or can be mounted so that their heights are adjustable.
When being inserted inside the storage room 2, the third storage 40 can be positioned between the first storage 10 and the door 20. When being extracted to the outside of the storage room 2, the third storage 40 can be positioned to be spaced apart from the first and second storages 10 and 30. The size of the third storage 40 can be smaller than that of the door 20. If the third storage 40 is inserted inside the storage room 2, and the door 20 is closed, the third storage 40 can be positioned at the rear of the door 20. If the third storage 40 is inserted inside the storage room 2, and the door 20 is closed, the third storage 40 can be positioned between the first and second storages 10 and 30. That is, if the third storage 40 is inserted inside the storage room 2, and the door 20 is closed, the third storage 40 can be positioned at the front of the first storage 10, and the second storage 30 can be positioned at the front of the third storage 40. If the door 20 is opened, and the third storage 40 is extracted to the outside of the storage room 2, the third storage 40 can be disposed to protrude in the direction opposite to the door 20. Any one of the second and third storages 30 and 40 can be positioned at one of the front, rear, left and right sides of the storage room 2, and the other of the second and third storages 30 and 40 can be positioned at the other of the front, rear, left and right sides of the storage room 2. When the door 20 is opened, the third storage 40 can be positioned at the front left side of the storage room 2. When being extracted to the outside of the storage room 2, the third storage 40 can be positioned at the front right side of the storage room 2. When the door 20 is opened, the third storage 40 can be positioned at the front right side of the storage room 2. When being extracted to the outside of the storage room 2, the third storage 40 can be positioned at the front left of the storage room 2. When being extracted to the outside of the storage room 2, at least a portion of the third storage 40 can be disposed opposite to the second storage 30 mounted to the door 20 in the lateral direction. If the door 20 is opened, and the third storage 40 is extracted to the outside of the storage room 2, the first storage 10 can be viewed between the second and third storages 30 and 40, and storage products inserted/extracted into/from the first storage 10 can be inserted/extracted between the second and third storages 30 and 40.
When being extracted to the outside of the storage room 2, the third storage 40 can be disposed to have an obtuse inclination angle θ2 with the front surface 3 of the storage room 2. When the door 20 is opened, the third storage 40 can be disposed to be inclined in the opposite direction to the door 20. The third storage 40 can be disposed in a first mode where the third storage 40 is positioned at the rear of the door 20, or can be disposed in a second mode where at least a portion of the third storage 40 is opposite to the door 20 and the second storage 30 in the lateral direction. The first mode is a mode in which the third storage 40 is inserted inside the storage room 2, and the door 20 is closed. The first mode can be a mode in which storage products are kept in the storage room 2. The second mode is a mode in which at least a portion of the third storage 40 is opposite to the door 20 and the second storage 30 in the lateral direction. The second mode can be a mode in which storage products are inserted/extracted into/from the storage room 2.
The third storage 40 can be inserted into the storage room 2 while being slidingly moved, and can be extracted to the outside of the storage room 2 while being slidingly moved. The third storage 40 can be inserted into the storage room 2 while being rotatably moved, and can be extracted to the outside of the storage room while being rotatably moved. A portion of the third storage 40 can be rotatably moved, and another portion of the third storage 40 can be slidingly moved to the rotatably moved portion. When the third storage 40 is rotatably moved, the rotational center of the third storage 40 can be positioned in the main body 4.
The description that follows focuses on an example in which a portion of the third storage 40 is rotatably moved, and another portion of the third storage 40 is slidingly moved to the rotatably moved portion. Other implementations are possible.
The third storage 40 can include rotary members 50 and 51 rotatably connected to the main body 4, and a frame 60 sliding along the rotary members 50 and 51 and having storage products kept therein.
The third storage 40 can include one or more keeping portions 41, 42 and 43 in which storage products are kept. Each of the keeping portions 41, 42 and 43 can include a shelf or basket. Each of the keeping portions 41, 42 and 43 can include at least one shelf, can include at least one basket, or can include at least one shelf and at least one basket. The keeping portions 41, 42 and 43 may be arranged to be vertically spaced apart from one another. All the keeping portions 41, 42 and 43 can be positioned at the frame 60. Some of the keeping portions 41, 42 and 43 can be positioned at the frame 60, and the other of the keeping portions 41, 42 and 43 can be positioned at the rotary members 50 and 51. The third storage 40 can have openings 44 and 45 formed between the keeping portions 41, 42 and 43. Each of the openings 44 and 45 can be formed to have a size in which storage products can be inserted/extracted into/from the first storage 10 by passing through the opening. Cooling air can pass through the openings 44 and 45. The cooling air in the first region can cool storage products in the third region by passing through the openings 44 and 45 and then flow in the second region. The cooling air in the second region can pass through the openings 44 and 45 and then return to the first region.
A rotational axis 52 that becomes a rotational center of each of the rotary members 50 and 51 can be mounted in the main body 4, and the rotary members 50 and 51 can be rotated about the rotational axis 52. When being rotated to the inside of the storage room 2, the lateral width L1 of each of the rotary members 50 and 51 can be formed shorter than the width L2 between left and right walls of the storage room 2. The rotational center of each of the rotary members 50 and 51 can be positioned inside the storage room 2. The rotational axis of each of the rotary members 50 and 51 can be mounted closely to one of the left and right walls of the storage room 2, which is closer to the rotational center of the door 20. For example, in a case where the door 20 is mounted to be laterally rotated at the left side of the main body 4, the rotational center of each of the rotary members 50 and 51 can be mounted closer to the left wall of the storage room 2. On the contrary, in a case where the door 20 is laterally rotated at the right side of the main body 4, the rotational center of each of the rotary members 50 and 51 can be mounted closer to the right wall of the storage room 2. Each of the rotary members 50 and 51 can be mounted in plural numbers in the main body 4, and the plurality of rotary members 50 and 51 can be arranged to be vertically spaced apart from one another. The upper rotary member 50 can guide an upper portion of the frame 60 to be slidingly moved. The upper rotary member 50 can be connected to one of the left and right walls of the storage room, which is closer to the rotational center of the door 20, through the rotational axis 52. The upper rotary member 50 can be connected to an upper wall of the storage room 2 through the rotational axis 52.
The lower rotary member 51 can guide a lower portion of the frame 60 to be slidingly moved. The lower rotary member 51 can be connected to one of the left and right walls of the storage room, which is closer to the rotational center of the door 20, through the rotational axis 52. The lower rotary member 51 can be connected to a lower wall of the storage room 2 through the rotational axis 52.
When being moved to protrude to the outside of the storage room 2, the frame 60 can be laterally spaced apart from the door 20. The frame 60 can have a gap T between the frame 60 and the door 20 when being protruded to the outside of the storage room 2. The gap T when the frame 60 is maximally protruded to the outside of the storage room 2 can be shorter than the lateral width between the left and right walls of the storage room 2. The gap T when the frame 60 is maximally protruded to the outside of the storage room 2 can be greater than 1⁄3 of the lateral width between the left and right walls of the storage room 2. The gap T when the frame 60 is maximally protruded to the outside of the storage room 2 can be smaller than the lateral width between the left and right walls of the storage room 2.
FIG. 6 illustrates an example of the third storage. As shown, the frame 60 can include the keeping portions 41, 42 and 43, and an outer frame 62 to which the keeping portions 41, 42 and 43 are mounted.
The outer frame 62 may have a quadrangular ring shape, and can be opened in the front-back direction. The outer frame 62 can allow the rotary members 50 and 51 to be internally or externally inserted. In a case where the rotary members 50 and 51 are internally inserted into the outer frame 62, space portions into which the rotary members 50 and 51 are inserted can be formed at upper and lower portions of the outer frame 62, respectively. An upper space portion into which the rotary member 50 is internally inserted can be formed at the upper portion of the outer frame 62. A lower space portion into which the rotary member 51 is internally inserted can be formed at the lower portion of the outer frame 62.
Each of the keeping portions 41, 42 and 43 can include a support 64 having storage products put thereon, and a holder 66 that prevents the storage products put on the support 64 from being overturned. The holder 66 can include a front holder 67 preventing the storage products put on the support 64 from being overturned forward, and a rear holder 68 preventing the storage products put on the support 64 from being overturned backward.
The left side of the support 64 can be connected to a left portion of the outer frame 62, and the right side of the support 64 can be connected to a right portion of the outer frame 62. The support 64 can be formed in a planar shape. The support 64 can be horizontally disposed.
The holder 66 can be connected to the support 64, or can be integrally formed with the support 64. The holder 66 can be spaced apart from the support 64. Any one of the front and rear holders 67 and 68 can be connected to the support 64, or can be integrally formed with the support 64. The other of the front and rear holders 67 and 68 can be connected to the support 64, or can be integrally formed with the support 64.
The left side of the front holder 67 can be connected to the left portion of the outer frame 62, and the right side of the front holder 67 can be connected to the right portion of the outer frame 62. The front holder 67 can be formed in a rod shape disposed in the lateral direction. The front holder 67 can be formed in the shape of a plate body disposed along the lateral direction.
The left side of the rear holder 68 can be connected to the left portion of the outer frame 62, and the right side of the rear holder 68 can be connected to the right portion of the outer frame 62. The rear holder 68 can be formed in a rod shape disposed in the lateral direction. The rear holder 68 can be formed in the shape of a plate body disposed along the lateral direction.
Any one of the front and rear holders 67 and 68 can be disposed lower than the other of the front and rear holders 67 and 68 so that the entrance/exit of storage products can be facilitated. In each of the keeping portions 41, 42 and 43, the height of the upper end of any one of the front and rear holders 67 and 68 can be lower than that of the upper end of the other of the front and rear holders 67 and 68. In each of the keeping portions 41, 42 and 43, the front and rear holders 67 and 68 can be disposed to partially overlap with each other in the front-back direction. The upper end of one of the front and rear holders 67 and 68, of which height is lower than that of the upper holder of the other of the front and rear holders 67 and 68 can be higher than the lower end of the other of the front and rear holders 67 and 68. When the third storage 40 is inserted inside the storage room 2 or when the third storage 40 is extracted to the outside of the storage room 2, the positions of the front and rear holders 67 and 68 can be changed in the front-back direction. The third storage 40 also may be configured such that the positions of the front and rear holders 67 and 68 cannot be changed in the front-back direction. In a case where the positions of the front and rear holders 67 and 68 are not changed in the front-back direction in the third storage 40, the height of the upper end of the front holder 67 may be disposed lower than that of the upper end of the rear holder 68.
Meanwhile, the holder 66 can be formed in a quadrangular ring shape, and the space between the front and rear holders 67 and 68 can be formed to be opened in the vertical direction. The holder 66 can be spaced apart from the support 64 above the support 64. That is, the front and rear holders 67 and 68 can be integrally formed to form a ring shape that is arranged along the lateral direction.
Below, the operation of the refrigerator configured as described above will be described.
First, the door 20 can be rotated about the hinge member 22. At this time, the front surface 3 of the storage room 2 is open, and the second storage 30 can be exposed to the outside while being fixed to the door 20. As the front surface 3 of the storage room 2 is opened, the third storage 40 is exposed through the front surface 3 of the storage room 3. If a user pulls forward the third storage 40 while holding the third storage 40, the frame 60 and the rotary members 50 and 51 can be rotated about the rotational axis 52 of the rotary members 50 and 51. At this time, a portion of the frame 60 can be protruded forward from the storage room 2 by passing through the front surface 3 of the storage room 2. At this point, the third storage 40 is entirely inclined with respect to the front surface 3 of the storage room 2. Particularly, the third storage 40 can be disposed to be inclined in the opposite direction to the door 20. For example, in a case where the door 20 is inclined to have an obtuse inclination angle in the front left direction of the storage room 2, the third storage 40 can be inclined to have an obtuse inclination angle in the front right direction of the storage room 2. If a user pulls the frame 60 in the length direction of the rotary members 50 and 51 while holding the frame 60, the frame 60 is rectilinearly moved in the inclination direction of the outside of the storage room 2, and the third storage 40 is moved to the side opposite to the second storage 30 in which the keeping portions 31, 32 and 33 are mounted to the door 20. The keeping portions 41, 42 and 43 can be primarily rotated about the rotational axis 52 of the rotary members 50 and 51 and then secondarily moved rectilinearly in the direction inclined to the length direction of the rotary members 50 and 51.
At this time, the first storage 10 can be viewed between the second and third storages 30 and 40, and the second and third storages 30 and 40 can be exposed forward together with the first storage 10. When the door 20 and the third storage 40 are manipulated as described above, storage product keeping components (e.g., the shelves, baskets and keeping portions) may be spread in a wider region than that when the refrigerator does not include the third storage 40, and the user can easily recognize a large quantity of storage products. In addition, the user may be able to easily insert/extract a large quantity of storage products into/from the refrigerator.
The insertion of the third storage 40 and the closing of the door 20 can be performed in reverse order. If the user pushes the frame 60 in the direction of the rotational axis 52 of the rotary members 50 and 51 while holding the frame 60, the frame 60 can be slid along the rotary members 50 and 51. Subsequently, if the user pushes backward the frame 60, the frame 60 is inserted into the storage room 2 while being rotated, together with the rotary members 50 and 51, about the rotational axis 52 of the rotary members 50 and 51.
