The invention can, however, be modalized in many different ways and should not be interpreted as being limited to the modalities shown here; in addition, those alternative modalities included in other regressive inventions or falling within the spirit and scope of this report will fully convey the concept of the invention to those skilled in the art.
For convenience of description, although a side-by-side refrigerator is described as an example in the modalities, this report is not limited to it. For example, all types of refrigerator including a door that can be opened by rotating it can be applied to the modalities.
Fig. 1 is a perspective view of a refrigerator according to an embodiment. Fig. 2 is a perspective view of a refrigerator with a first door open according to an embodiment. Fig. 3 is a perspective view of a refrigerator with a second door open according to an embodiment.
Referring to Figs. 1a 3, a refrigerator 1 according to an embodiment includes a cabinet defining a storage space and doors 20 and 30 opening and closing the storage space. Here, an external appearance of the refrigerator 1 can be defined by cabinet 10 and ports 20 and 30.
The interior of cabinet 10 can be partitioned on left and right sides to define a freezer compartment 102 and a cooler compartment 104. Doors 20 and 30 can include a freezer compartment door 20 and a cooler compartment door 30, which opens and closes the freezing compartment 102 and the refrigerating compartment 104, respectively.
Also, an accommodation device for defining a separate storage space, separate from the interior of the refrigerating compartment 104, can be arranged on the refrigerating compartment door 30. Thus, in a state where the refrigerating compartment door 30 is closed, the interior of the refrigerant compartment 104 can be defined as a first storage compartment 104 and the interior of the accommodation device can be defined as a second storage compartment 405.
The refrigerant compartment door 30 can include a first door 310 opening or closing the first storage compartment 104 and a second door 340 for opening or closing the second storage compartment 405.
In detail, an opening 316 can be defined in an upper portion of the first door 310. The opening 316 can extend from an adherent part 313 to a position adjacent to an upper end of the first door 310. Also, the opening 316 can extend to an adjacent position for each of both side ends of the first door 310. The accommodation device 40 can be arranged on a rear surface of the first door 310 corresponding to a rear side of the opening 316. The accommodation device 40 is shaped open in a frontal direction. Also, food can be accessible in the accommodation device 40 through opening 316.
A seal 319 can be arranged around a rear surface of the refrigerant compartment door 30 to contact a circumference of a front surface of the cabinet 10 when the refrigerant compartment door 30 is closed. The seal 319 can be formed of a compressible and elastically deformable material. Also, a magnet can be arranged inside the seal 319 and thus attached closely to the cabinet 10.
Also, an opening 316 through which food accommodated within the accommodation device 40 is accessible in a state where the first door 310 is closed can be defined in the refrigerant compartment door 30. Thus, in a state where the first door 310 covers the refrigerant compartment 104, opening 316 can be opened to place or remove food from accommodation device 40.
The opening 316 can be a size corresponding to that of a front surface of the accommodation device 40. The opening can be defined vertically from an upper end of the first door 310 to a position of the adherent part 313 and horizontally defined to a region except for a portion of each of both side ends of the first door 310. Thus, opening 316 may be significantly different from a domestic bar used in a general refrigerator in size and use.
The second door 340 can open or close the opening 316. Also, the second door 430 can be rotatably arranged on the first door 310 by a first hinge 51. The first hinge 51 can be arranged on the upper end of the compartment door refrigerant 30 and the front surface of the refrigerant compartment door 30 corresponds to a lower side of the opening 316. The first hinge 51 is rod-coupled to the upper and lower ends of the second door 340. Thus, the second door 340 can be rotatable independently in a state where the first door 310 is closed to selectively open or close the opening 316.
The second door 340 can have a front surface formed of the same material as those of the first door 310 and the freezing compartment door 20. Also, a design or pattern can be arranged continuously on the front surface of the second door 340. When the second door 340 is closed, the front surface of the second door 340 can be arranged on the same plane as that of the front surface of the refrigerant compartment door 30 disposed on the lower side of the second door 340.
Also, when the second door 340 is closed, the upper end and both side ends of the second door 340 can be arranged in the same position as those of the refrigerant compartment door 30. The lower end of the second door 340 can extend to a position corresponding to an area over which the adherent part 313 of the refrigerant compartment door 30 is arranged. That is, the lower end of the second door 340 can extend to a position corresponding to a stepped portion over an area in which the adherent part 313 of the refrigerant compartment door 20 is arranged. Thus, the second door 340 can be integrated with the first door 310 in the state where the second door 340 is closed. Also, when viewed from the front side of the refrigerator, a portion to which the second port 340 is connected can be covered to realize the sense of unity.
An inwardly protruding projection 342 may be arranged on a rear surface of the second door 340. A portion of the second surface of the second door 340 may project to define the projection 342. Also, the projection 342 may have a shape corresponding to that of the opening 316. Thus, when the second door 340 is closed, the projection piece 342 can be arranged inside the opening 316 and coupled in a formatted way to the opening 316 to first prevent cold air from leaking.
An upper and lower portion of the projection 342 can be staggered with each other. The lower projection 342a can be arranged on the lower stepped portion of the projection 342. The lower projection 342a can be arranged in a position lower than that of an upper portion of the projection 342. Also, the lower projection 342a can extend to a lower end of the portion upper projection 342. When the second door 340 is closed, a folded shelf 270 can be arranged on the lower projection 342a. Thus, the projection 342b can have a thickness corresponding to that of a shelf 370.
A joint 344 can be arranged along a circumference of the projection 342. The joint 344 can be formed of a material such as rubber or silicone which can be elastically deformed. When the second door 340 is closed, gasket 344 can be attached close to the front surface of the refrigerating compartment door 30. At this time, gasket 344 can be compressed to prevent cold air inside the accommodation device 40 from leaking.
A second door switch 349 for detecting the opening / closing of the second door 340 can be arranged on an upper end of the refrigerant compartment door 30. The second door switch 349 can be configured to produce an alarm signal to the outside when the second door 340 is not closed.
A locking unit can be arranged at a side end of the rear surface of the second door 340 away from a rotating rod of the second door 340 and a side end of the refrigerant compartment door 30 corresponding to the side end of the rear surface of the second door 340. The locking unit can maintain the closed state of the second door 340 and switch to a restricted state of the second door 340 by a pressing operation to selectively restrict the second door 340.
The locking unit can have the same structure as that of a general switch. Also, the locking unit can include a locking device 60 disposed on one side of the refrigerant compartment door 30 and include a locking slot 317 in which a locking hook 341 is inserted and the locking hook 341 disposed on the second door 340 Considering that the locking unit has a structure that is widely used, in a general refrigerator, detailed descriptions regarding the structure will be omitted.
A shelf 370 that is rotatable in a front direction can be arranged on one side of the first door 310. A connection assembly 390 connecting shelf 370 to the second door 340 can be arranged on one side of the second door 340. Thus, the rotation of the shelf 370 can be associated with opening / closing second door 340.
From now on, shelf 370 will be described in greater detail with respect to the accompanying figures.
Fig. 4 is a view illustrating a state in which a shelf is rotated by opening the second door.
Fig. 5 is a view illustrating a rear surface of the first door in a state where the second door is closed. Fig. 6 is a view illustrating a state in which a joining member and a connection set are coupled together according to an embodiment.
Referring to Figs. 3 to 6, both ends of the shelf 370 can be rod-coupled into the opening 316 so that it is rotatable while crossing the front surface of the first door 310. A shelf rotation rod 371 can be arranged on each. from both the left and right sides of a shelf 370. The shelf rotation rods 371 can be coupled by rod to both the left and right sides of the opening, respectively. Here, the shelf rotation rod 371 can be arranged on at least one side of a shelf 370 or opening 316.
The shelf 370 can have a size corresponding to a horizontal width of the opening 316 so that the shelf 370 can be received inside the opening 316. Also, the shelf 370 can have a size corresponding to that of the lower projection 342a so that the shelf 370 can be received inside the lower projection 342a when the second door 340 is closed, as shown in Fig. 5.
A junction member 380 to which a connection assembly 390 which will be described in detail below can be arranged on a bottom surface of a shelf 370. Junction member 380 may include a junction coupling part 381 which is coupled to a shelf 370 and a junction receiving piece 382 where one end of the connection assembly 390 is rotatably received.
In detail, the coupling part 381 has a flat shape. Also, screw holes 381a are defined respectively on both sides of the coupling coupling part 381 so that the coupling coupling part 381 is coupled to a shelf 370. Thus, the coupling member 380 is mounted on a shelf 370 by screws attached to the 381a screw holes.
The junction receiving part 382 can receive a ball-shaped connection piece 391 a constituting the connection assembly 390 to surround the ball connection piece 391a. A bottom surface of the junction coupling part 381 corresponding to the junction receiving part 382 can be opened so that the ball connection part 391a is inserted. Also, a cut-out piece 382a that is cut to guide a path through which a rod 382 is rotated can be arranged on one side of the joint receiving piece 382.
The cut-out piece 382a may allow a tie rod 391 to be rotated freely and prevent the ball connection piece 391a from being separated from the tie-in receiving piece 382. A guide piece 382b protrudes from one side of the cutout piece 382a. Guide piece 382b protrudes from cutout 382a to define a predetermined path over cutout 382a. Also, when the connecting rod 391 is rotated, the guide piece 382b guides the movement of the connecting rod 391. As shown in Fig. 7, the ball connection piece 391a can be received at both ends of the cutout part 382a to allow the ball connection piece 391a to maintain a stable position thereof. Here, the ball connection piece can be arranged at both ends of the cutout piece 382a when the shelf 370 is completely folded or extended.
A restraint member 372 for restraining connection assembly 390 may be additionally disposed on one side of shelf 370. Restraint member 372 is disposed on a bottom surface of a shelf 370. Also, restraint member 372 may define as space spaced from the bottom surface of the shelf 370. A side of the connection assembly 390 can be received between a shelf 370 and the restriction member 372 to prevent the connection assembly 390 from being moved to an unwanted position when a shelf 370 is rotated.
A connection set assembly part 342b may be arranged on a lower side of the rear surface of the second door 340. The connection set assembly part 342b may be arranged on the lower projection 342a of the second port 340. The assembly part connection set 342b can be recessed to receive one end of connection set 390. Also, connection member 395 can be vertically attached by rod to connection set assembly part 342b so that 395 is rotatable in the same direction of rotation as that of the second door 340.
From now on, the connection set will be described in more detail with respect to the accompanying figures.
Fig. 7 is a view illustrating a state in which a joining member and a connection set are coupled together according to an embodiment. Fig. 8 is a view that illustrates an operation of the connection set.
Referring to Figs. 7 and 8, the connection set 381 includes the connecting rod 391 connected to the connecting member 380, the damping unit 381 which adjusts the length of the connecting rod 391 and absorbs shock during the movement of the connecting rod 394, a member assembly 398 mounted on the assembly part of the connection assembly 342b of the second port 340, a connection member 395 rotatably coupled to the assembly member 395, and a rod connecting the connecting rod 391 to the connecting member 395.
In detail, the connecting rod 391 can be shaped like a rod having a predetermined length. The ball connection piece 391a having a ball shape can be arranged on one end of the joining rod 391. Thus, the ball connecting piece 391a can be rotatably coupled to the joining member 380. The other end of the rod junction 391 can be inserted into rod 382. Junction rod 391 can be placed and removed from rod 382 according to the movement paths of connection assembly 390 during the rotation of a shelf 370.
The rod 382 can receive one end of the joint rod 391 and can be rod-coupled to the connecting member 395. In detail, at least the inner portion of the rod 382 can be left hollow to define a space for receiving the joint rod 391 and the damping unit 394. A rod cover 393 in which the joining rod 391 is inserted can be arranged at one end of the rod 382. The rod cover 393 can be coupled to the end of the rod 382. Both ends of the cap of rod 393 can be opened to receive joint rod 391 and at least a portion of the damping unit 394. A rod connection piece 392a can be arranged on the other end of rod 382. Rod connection part 392a can be received inside the connecting member 395. The rod connecting piece 392a can be coupled to one side of the connecting member 395 by a rod rod 397a to allow rod 382 to be vertically rotated with respect to rod rod 397a.
One end of the rod connecting piece 392a can have a curved surface 382b having a predetermined curvature as shown in Fig. 8. Thus, even if a user's hand contacts the connecting rod 392 when the rod 382 is rotated by According to the rotation of the second door 340, the hand may not be caught by the connecting rod 392 and will slide along the curved surface, thus preventing a negligent accident from occurring.
The damping unit 394 can be arranged inside the rod 382 and support one end of the joint rod 391 to absorb the shock caused by the movement of the moving joint rod 391. The damping unit 394 may include a spring 394a supporting one end of the rod junction 391, a stop 394b that slides inside the rod 382 and supports the spring 394a, a 0-ring 394c mounted on the stop 394b and contacting an internal surface of the rod 382 to provide a frictional force, a washer 394d mounted on the stop 394b to prevent the 0-ring from being separated, and a pressure ring 394e securing the washer 394d and preventing the stop 394b from being moved backwards.
Thus, when shelf 370 is rotated, joint rod 391 can be placed or taken out to smoothly rotate shelf 370. When joint rod 391 is moved while being placed and taken out, spring 394a can be extended or compressed. Accordingly, the stop 394b can be moved to absorb transmitted shock from the junction stick 391, thereby decreasing a movement speed of the junction stick 391.
Since the connecting rod 391 is slowed down, a sudden rotation of the shelf 370 can be avoided.
Although the damping unit 394 is arranged on the end of the rod 382 in the current mode, the present report is not limited to it. For example, the damping unit 394 can be arranged on both ends of the rod 382 so that the rod 382 can experience variations of impact at both ends of the rod 382. The mounting member 398 is inserted into the assembly assembly part connection 342b. The mounting member may include a cup 398a that defines a receiving space for the connecting member 395 and a flange 398b arranged around the cup 398a and coupled to the second port 340 by means of a screw.
A rotating rod of the connecting member 396a can be arranged in the cup 398a to vertically traverse the cup 398a. The rotating rod of the connecting member 396a can vertically traverse the connecting member 395 received in the cup 398a to serve as a center of rotation of the connecting member 395. The connecting assembly 390 can be rotated smoothly by the connecting member 395. The connecting member 395 may include a rod coupling part 396 into which the connecting member rotation rod 396a is inserted and a rod connecting part receiving part 397 receiving the rod connecting part 392a. A vertically open rod insertion hole 396b can be defined in rod coupling part 396. The connecting member rotation rod 396a can be inserted into the rod insertion hole 396b to rotate the connecting member 395 with respect to the rod of connection member rotation 396a. The rod 382 can be received inside the rod connection piece receiving part 397. Thus, the rod connection piece receiving part 397 can be arranged on both sides of the rod 382 to move the rod 382 up and down. The rod rod 397a can pass through the rod connector part receiving part 397 and the rod connector part 392a to allow vertical movement of the rod connecting 382.
Thus, the rod 382 can be rotated freely in the vertical and horizontal directions, that is, the direction of rotation of the second door 340 and the direction that crosses the direction of rotation of the second door 340 by the connecting member 395. Thus, when the second door 340 is opened or closed, the second door 340 can be further rotated smoothly during folding or spreading of shelf 370.
From now on, a lower hinge assembly disposed on the second door will be described.
Fig. 9 is a view of a lower hinge assembly in a state where the second door is closed. Fig. 10 is a view of the lower hinge assembly in a state where the second door is opened.
Referring to figs. 9 to 10, a lower end of the second door 340 is supported by a hinge support 53. The hinge support 53 can be arranged on a front surface of the first door 310 to support the second door 340 from a lower side. Also, hinge support 53 can be coupled to a lower hinge assembly 54 disposed to second door 340.
When the second door 340 is opened, the lower hinge assembly 54 can automatically open the second door 340 at a predetermined angle and then prevent the second door 340 from being further rotated after the second door 340 is rotated at the predetermined angle.
In detail, the lower hinge assembly 54 includes the hinge fixture 55 attached to the hinge bracket 53 and the hinge rotation part 56 contacting the hinge fixture 55 and fixedly disposed within the second door 340 so that this 56 is rotated together with the second door 340 when the second door 340 is rotated.
The hinge fixture 55 may include an insertion projection 551 inserted in the hinge support 53 and the lower cam 552 disposed above the insertion projection 551. The insertion projection 551 can have a shape corresponding to that of the hinge support 53 is fixed and thus be coupled in a formatted manner to the hinge support 53. Thus, the hinge fixing piece 55 can be maintained in a state that is fixed to the hinge support 53 when the second door 340 is rotated. A downwardly inclined first meat surface 552a can be arranged on a top surface of the bottom meat 552. Also, a second inclined meat surface 552b again from a lower end of the first upward meat surface can be arranged on the bottom surface. top of the bottom meat 552. The first meat surface 552a can be continuously connected to the second meat surface 552b. Also, two first and second meat surfaces 552a and 552b can be provided continuously along a circumference of the lower meat type surface 552.
A fastening guard 561 can be arranged around a side surface of the hinge rotation part 56. The hinge rotation part 56 can be arranged inside the hinge receiving part 340a mounted inside the second door 340. A groove of projection receiving 340b can be recessed around an internal surface of the hinge receiving skin 340a. The fixing projection 561 can be received within the projection receiving groove 340b. So, the play; hinge rotation means 56 can be mounted in a state where it is integrally rotated with the second door 340. An upper cam 562 is arranged on a bottom surface of the hinge rotation part 56. The upper cam 562 has a third cam surface Downward sloping 562a and a fourth cam surface 562b slanted again from a lower end of the upward third cam surface 562a. The third cam surface 562a can be connected continuously to the fourth cam surface 562b. Also, two third and fourth cam surfaces 562a and 562b can be provided continuously along a circumference of the upper surface of the lower cam 552. The third and fourth cam surfaces 562a and 562b contact the first and second surfaces 552a and 552b in the formats corresponding, respectively.
The upper surface of the hinge rotation part 56 can be supported by an elastic member 563 such as a spring arranged within the hinge receiving part 340a. Thus, the bottom surface of the rotating part of; hinge 56 can continuously contact the upper surface of the hinge fixture 55. Also, the first and second meat surfaces 552a and 552b of the hinge fixture 55 and the third cam surface 552a and 562b of the hinge rotation part 56 can be moved according to the rotation of the second door 340 while contacting the second and fourth cam surfaces 552b and 562b.
For example, in the state where the second door 340 is closed, the first and second cam surfaces 552a and 562a can contact each other as shown in Fig. 9. When the first cam surface 552a and the third cam surface 562a are inclined downward to release the restriction of the second door 340, the third cam surface 562a can slide down along the first cam surface 552a by a weight of the second door 340. Thus, when the second door 340 is opened, the hook lock 341 can be released to open the second door 340 using the weight of the second door 340 without applying additional force.
When the second door 340 is rotated by an angle greater than a predetermined angle during opening, the first and third cam surfaces 552a and 562a may not contact each other, but the second and fourth cam surfaces 552b and 562b can contact each other. Since the second and fourth cam surfaces 552b and 562b are tilted downward, the more the second door 340 is rotated, the more the rotation speed of the second door 340 can be decreased. i
When the second port 340 is rotated by a predetermined angle, for example, about 110, the second cam surface 552b can completely contact the fourth cam surface 562b as shown in Fig. 10. Also, the elastic member 563 can be compressed to prevent hinge rotation part 56 from being further rotated. In this state, the rotation of the second door 340 can be stopped and restricted. The degree of opening of the second door 340 can be determined by the curvatures of the second and fourth meat surfaces 552b and 562b and the elasticity of the elastic member 563. However, considering the shelf 370 connected with the rotation of the second door 340, the second door can be opened at an angle of about 110o.
Hereinafter, an operation of the second refrigerator door will be described according to an embodiment.
When the second door 340 is closed, the shelf 370 can be attached close to the lower ledge 342a in the folded state. Also, in the state where the shelf 370 is folded, the connection assembly 390 can also be folded.
When the second door 340 is closed, the user can manipulate the opening of the second door 340 by releasing the lock hook restriction 341. While the lock hook restriction 341 is released, the second door 340 can be rotated automatically by the hinge assembly. lower 54;
Also, the shelf 370 connected to the connection set 390 can be extended while the second door 340 is rotated. The connection set 390 can be rotated together with the shelf 370. Here, the shelf 370 is slowly moved down, damping the damping unit 394.
The second door 340 is automatically opened by the lower hinge assembly 54 at a predetermined angle. Then, when the shelf 370 is fully extended so that the top surface of a shelf 370 is perpendicular to the front surface of the first door 310, the rotation of the second door 340 can be staggered. At this time, the second door 340 can be rotated at an angle of about 110 ° and the second door 340 can be gradually decelerated by the lower hinge assembly 54 and stopped just before the shelf 370 being completely spread out.
When shelf 370 is fully extended, connection assembly 390 can also be completely spread out to support shelf 370. At the same time, the bottom surface of shelf 370 can be supported by the lower end of opening 316. Thus, shelf 370 can be kept in a stable state. When the shelf 370 is fully extended, the connecting rod 391 of the connection assembly 390 can be maintained to receive at the end of the cutout 382a of the connecting member 380. Furthermore, considering that the second door 340 is not additionally opened by the lower hinge assembly 54, shelf 370 can be kept in the 5 most stable state. INDUSTRIAL APPLICABILITY
According to the modalities, as long as the shelf is extended and connected with the opening of the second door, the convenience of use can be further improved and industrial applicability can be high.
