Description

Technical Field

[0001] The invention relates to a refrigerator. Background Art

[0002] Generally, a refrigerator is a household appliance that can store food at low temperature in an internal storage space shielded by a refrigerator door. It is configured to cool the interior of the storage space using cold air generated by heat exchange with a refrigerant circulating in a refrigeration cycle, thereby being able to preserve the stored food in an optimal state.

[0003] The refrigerator can be placed independently in a kitchen or bedroom, etc., or can be stored in a furniture cabinet in the kitchen.

[0004] The refrigerator may include a body forming a storage space and a door connected to the body and opening and closing the storage space.

[0005] For example, when the refrigerator is installed in a furniture cabinet, there is a risk that the door may collide with the furniture cabinet during the opening process of the door, thereby limiting the opening angle of the door.

[0006] International Publication WO2019 / 007278A1, which is an existing document, discloses a refrigerator.

[0007] The refrigerator includes: a box body; a door for opening and closing the box body; a hinge body fixed to the box body; and a guide block fixed to the door.

[0008] The hinge body includes a position determining shaft and a guide shaft, and the guide block includes a position determining groove into which the position determining shaft is inserted and a guide groove into which the guide shaft is inserted.

[0009] According to the prior art, the hinge body is provided with a positioning shaft and a guide shaft, and the positioning shaft and the guide shaft are independently inserted into the positioning groove and the guide groove, respectively. Therefore, there is a disadvantage that the structures of the hinge body and the guide block become complicated. Summary of the invention

[0010] The present embodiment provides a refrigerator capable of increasing the opening angle of a door through a simple structure.

[0011] Alternatively or additionally, the present embodiment provides a refrigerator whose door opens as the rotation center of the door moves, thereby preventing interference with surrounding structures during the door opening process.

[0115] Figure 1 is a front view of a refrigerator according to a first embodiment, Figure 2 yes Figure 1 Magnified view of part A. Figure 3 It is a diagram showing a part of a bottom view of the refrigerator according to the first embodiment.

[0116] Reference Figures 1 to 3 The refrigerator 1 of this embodiment can be independently installed in the kitchen, or can be installed in a cabinet P or a wall. When the refrigerator 1 is installed in a cabinet P or a wall, the refrigerator 1 can be installed alone, or can be installed to be arranged side by side with other refrigerators.

[0117] The refrigerator 1 may include a housing 10 having a storage space. The refrigerator 1 may further include a door 20 for opening and closing the storage space.

[0118] The storage space may be divided into a first space at an upper side and a second space at a lower side, but is not limited thereto. The door 20 may also include a first door 21 for opening and closing the first space and a second door 22 for opening and closing the second space.

[0119] The first space is a refrigerator, the second space is a freezer, or they may be the opposite. Alternatively, the storage space may include a first space and a second space divided left and right. Alternatively, the storage space may be a single space, or the storage space may be opened and closed by a single door.

[0120] At least one of the first door 21 and the second door 22 may be a revolving door. Alternatively, the single door 20 may be a revolving door.

[0121] In the case of this embodiment, the revolving door 20 may be rotated by the hinge bracket 50 .

[0122] As an example, hinge brackets 50 of the same or different shapes may support the door 20 at the upper and lower sides of the door 20 .

[0123] As an example, Figure 2 The hinge bracket 50 supporting the lower side of the second door 22 is shown. The guide portion of the hinge bracket 50 described below (see Figure 4 The structure of the hinge bracket 530) can be applied to the structure of the hinge bracket disposed on the upper side or the lower side of the door 20. According to the position where the hinge bracket 50 supports the door 20, the hinge bracket 50 can be combined with the top surface of the box body 10, or combined with the bottom surface, or combined with the front surface, or combined with the side surface.

[0124] For convenience of description, it is described below that the hinge bracket 50 supports the door 20 to be rotatable.

[0125] The refrigerator 1 may further include an automatic closing device 60 that provides a closing force to the door 20 during the process of the door 20 closing after opening. Of course, the automatic closing device 60 may be omitted.

[0126] As an example, Figure 3 It is shown that the hinge bracket 50 supports the lower side of the door 20, and the automatic closing device 60 is arranged on the lower side of the door 20. Of course, it should be noted that the position of the automatic closing device 60 is not limited.

[0133] The automatic closing device 60 may include a main body 610 provided on the door 20. The automatic closing device 60 may include a rod 620 movably provided on the main body 610. As an example, the rod 620 may rotate relative to the main body 610 with the rotation center A1 as a reference. The rod 620 may be connected so as to be movable in a state of being elastically supported on the main body 610. As an example, the automatic closing device 60 may further include an elastic member for elastically supporting the rod 620.

[0134] The rod 620 may further include a contact portion 622 for contacting the hinge bracket 50. As an example, the contact portion 622 may be a rotatable roller or a deformable member.

[0135] In a state where the elastic member connected to the rod 620 accumulates elastic force, when the door 20 is closed, the elastic force acts as a closing force of the door 20, so that the door 20 can be automatically closed.

[0136] On the other hand, a gasket G may be provided on the back side of the door 20 . When the door 20 is closed, the gasket G may contact the front side 10 a of the housing 10 .

[0137] Figure 4 is a three-dimensional diagram of the hinge bracket of the first embodiment, Figure 5 4 is a top view of the hinge bracket of the first embodiment.

[0138] Reference Figures 3 to 5 The extension portion 510 may include one or more fastening holes 512. The fastening member may pass through the fastening holes 512 and be fastened to the box body 10.

[0139] As an example, the hinge body 520 may be formed in a plate shape.

[0140] At least a portion of the hinge body 520 may be inserted into the door 20 and guide the rotation of the door 20. Alternatively, at least a portion of the door 20 may be inserted into the hinge body 520 to guide the rotation of the door 20 through the hinge body 520.

[0141] The hinge body 520 may include a guide portion 530 .

[0142] The guide portion 530 may protrude from one side of the hinge body 520. As an example, the guide portion 530 may extend from one side of the hinge body 520 toward the door 20.

[0143] When the hinge body 520 is located at the lower side of the door 20, the guide part 530 may protrude from the top surface of the hinge body 520. Of course, when the hinge body 520 is located at the upper side of the door 20, the guide part 530 may protrude from the bottom surface of the hinge body 520.

[0144] At least a portion of the guide portion 530 may be inserted into the door 20 to guide the rotation of the door 20 .

[0145] The guide portion 530 may include a first member 532 (or a first pin). The first member 532 may guide the rotation of the door 20. As an example, the first member 532 may be formed in a cylindrical shape. Alternatively, the circumferential surface of the first member 532 may include a curved surface.

[0146] The guide portion 530 may further include a second member 534 (or a second pin). The second member 534 may guide the rotation of the door 20. As an example, the second member 534 may be formed in a cylindrical shape. Alternatively, the circumferential surface of the second member 534 may include a curved surface.

[0147] The first member 532 and the second member 534 may be spaced apart. The first member 532 may be spaced apart from the second member 534 in the Y-axis direction.

[0148] As an example, the Y-axis direction may be the front-to-back direction of the refrigerator, and as an example, the X-axis direction may be the left-to-right direction of the refrigerator. The front-to-back direction of the refrigerator may be the arrangement direction of the door 20 and the cabinet 10 when the door 20 is closed.

[0149] The minimum separation distance between the first member 532 and the second member 534 may be equal to or smaller than the diameter of the first member 532 or the second member 534 .

[0150] A portion of the first member 532 may overlap with the second member 534 in the Y-axis direction. Another portion of the first member 532 may not overlap with the second member 534 in the Y-axis direction.

[0151] When the hinge bracket 50 is set on the box body 10, the distance between the second component 534 and the front face 10a of the box body 10 (distance in the Y-axis direction) can be shorter than the distance between the first component 534 and the front face 10a of the box body 10 (distance in the Y-axis direction).

[0152] The distance between the first member 532 and the rotation center A1 of the rod 620 may be different from the distance between the second member 534 and the rotation center A1 of the rod 620. As an example, the distance between the first member 532 and the rotation center A1 of the rod 620 may be smaller than the distance between the second member 534 and the rotation center A1 of the rod 620.

[0153] The distance (X-axis distance) between the first side surface 20c adjacent to the hinge bracket 50 and the first member 532 may be different from the distance (X-axis distance) between the first side surface 20c and the second member 534. For example, the distance between the first side surface 20c and the first member 532 may be greater than the distance between the first side surface 20c and the second member 534.

[0154] A line connecting the center of the first member 532 and the center of the second member 154 may be inclined with respect to the X-axis and the Y-axis.

[0155] The hinge bracket 50 may further include a contact surface 540 that contacts the contact portion 622 of the rod 620 .

[0156] The contact surface 540 may be a surface of the hinge body 520 , or may be a surface of a member coupled to the hinge body 520 .

[0157] The contact surface 540 may include a first contact surface 541. The first contact surface 541 may be a surface that the rod 620 initially contacts during the process of closing the door 20 after the door 20 is opened.

[0158] When the door 20 is opened to a setting angle or more, the rod 620 does not contact the first contact surface 541. When the door 20 is closed to an angle smaller than the setting angle, the rod 620 may contact the first contact surface 541.

[0159] The first contact surface 541 may be inclined in a direction closer to the front surface 10 a of the box body 10 and farther away from the guide portion 530 .

[0160] The contact surface 540 may further include a second contact surface 542 extending from the first contact surface 541. The second contact surface 542 may be arranged to be inclined relative to the first contact surface 541.

[0161] The second contact surface 542 may be inclined in a direction closer to the front surface 10 a of the box body 10 and closer to the guide portion 530 .

[0162] When closing the door 20 , the rod 620 provides a closing force to the door 20 while moving along the second contact surface 542 , so that the door 20 can be automatically closed.

[0163] The contact surface 540 may further include a third contact surface 543 extending from the second contact surface 542. The third contact surface 543 may be arranged to be inclined relative to the second contact surface 542.

[0164] The third contact surface 543 may extend from the second contact surface 542 toward a direction approaching the guide portion 530 .

[0165] The hinge bracket 50 may further include a receiving groove 544 for receiving a portion of the rod 620 or reducing interference with the rod 620 when the rod 620 is in contact with the third contact surface 543 .

[0166] Figure 6 is a three-dimensional view of the door bracket of the first embodiment, Figure 7 It is a bottom view of the door bracket of the first embodiment.

[0167] Reference Figures 3 to 7 The door 20 may further include a door bracket 40. The door bracket 40 may interact with the guide portion 530 during the rotation of the door 20. The door bracket 40 may be integrally formed with the door 20 or combined with the door 20.

[0168] In the case where the door bracket 40 is coupled to the door 20 , the door bracket 40 may be coupled to a surface of the door 20 that faces the hinge body 520 .

[0169] As an example, the door bracket 40 may be coupled to the bottom surface of the door 20. The door bracket 40 may include one or more fastening holes 410 for fastening to the door 20. One side 401 of the door bracket 40 may be recessed. The fastening holes 410 may be formed in the recessed portion of the one side 401. One side 401 of the bracket 40 may be a surface facing the hinge body 520.

[0170] The door bracket 40 may further include another surface 402 located on the opposite side of the one surface 401 .

[0171] The door bracket 40 may be disposed at the door 20 and separated from the automatic closing device 60 .

[0172] The door bracket 40 may accommodate the guide portion 530. The door bracket 40 may further include an accommodation portion 420 for accommodating the guide portion 530. The door bracket 40 may also be formed integrally with the door 20, in which case the door 20 may include an accommodation portion 420 for accommodating the guide portion 530.

[0173] In this specification, the guide portion 530 of the hinge bracket 50 may be referred to as a first guide, and the receiving portion 420 of the door bracket 40 may be referred to as a second guide. In one embodiment, the second guide may interact with the first guide during the opening and closing process or the rotation process of the door 20. As an example, the first guide may be received in the second guide.

[0174] On the contrary, the first guide member may also be formed on the door bracket 40, and the second guide member may be formed on the hinge bracket 50. In this case, it can be understood that the second guide member is accommodated in the first guide member.

[0175] The receiving portion 420 may include a slit through which the guide portion 530 passes. As an example, the receiving portion 420 may include a single slit through which the first member 532 and the second member 534 pass.

[0176] The slit may include a first portion 421. The first portion 421 may extend from one end 421a toward a direction close to the front side 10a of the box body 10. The first portion 421 may extend from one end 421a toward a direction close to the first side surface 20c. A part or all of the first portion 421 may be arc-shaped.

[0177] One end 421a of the first portion 421 may be located closer to the automatic closing device 60 than the other end. One end 421a of the first portion 421 may be located closer to the front surface 20a of the door 20 than the other end.

[0178] The slit may further include a second portion 422 extending from the first portion 421. The other end of the first portion 421 may be connected to one end of the second portion 422. That is, the portion where the other end of the first portion 421 is connected to one end of the second portion 422 is a boundary portion 423 of the first portion 421 and the second portion 422.

[0179] The second portion 422 may extend from the boundary portion 423 in a direction away from the front side 10a of the box body 10. The second portion 422 may extend from the boundary portion 423 in a direction close to the first side surface 20c. A part or all of the second portion 422 may be arc-shaped.

[0180] The other end 422a of the second portion 422 may be located closer to the first side surface 20c than the boundary portion 423. The boundary portion 423 between the first portion 421 and the second portion 422 may be located closest to the front surface 10a of the box body 10.

[0181] A distance between one end 421 a of the first portion 421 and the front surface 20 a of the door 20 may be different from a distance between the other end 422 a of the second portion 422 and the front surface 20 a of the door 20 .

[0182] During the opening process of the door 20, the relative positions of the first member 532 and the second member 534 and the slit can be changed. When the door 20 is initially opened, the first member 532 and the second member 534 can be located in the first portion 421. When the door 20 is completely opened, the first member 532 and the second member 534 can be located in the second portion 422.

[0183] The length of the first portion 421 may be different from the length of the second portion 422. The length of the first portion 421 may be equal to or greater than the length of the second portion 422.

[0184] The first portion 421 may include a portion having a curvature different from that of the second portion 422 .

[0185] The door bracket 40 may further include a protrusion 425 protruding from the one surface 401 .

[0186] As an example, one protrusion 425 may be continuously formed along the periphery of the receiving portion 420. Alternatively, a plurality of protrusions 425 may be spaced apart and arranged along the periphery of the receiving portion 420. Alternatively, more than one protrusion 425 may be arranged around the periphery of the receiving portion 420.

[0187] The protrusion 425 can prevent the one side 401 of the door bracket 40 from directly contacting the hinge body 520. That is, the protrusion 425 can contact the hinge body 520. Therefore, the contact area between the door bracket 40 and the hinge body 520 can be reduced, thereby reducing friction.

[0188] Figure 8(a) is a diagram showing the positional relationship between the door bracket and the hinge bracket in the door closed state of the first embodiment, Figure 8 (b) is a diagram showing the positional relationship between the hinge bracket and the door when the door is opened at a first angle.

[0189] Fig. 9 (a) is a diagram showing the positional relationship between the hinge bracket and the door when the door is opened at a second angle larger than the first angle, Fig. 9 (b) is a diagram showing the positional relationship between the hinge bracket and the door when the door is opened at a third angle larger than the second angle. Fig.10 It is a diagram showing the positional relationship between the hinge bracket and the door when the door is opened to the maximum opening angle according to the present embodiment.

[0190] Figures 8 to 10 This is a picture of the door bracket and hinge bracket viewed from the bottom side of the refrigerator.

[0191] Reference Figures 3 to 10 When the door 20 is closed, the guide portion 530 may be located at the first portion 421 . That is, the first member 532 and the second member 534 may be located at the first portion 421 .

[0192] When the door 20 is closed, the first member 532 may be located closer to the front face 20a of the door 20 than the rotation center A1 of the rod 620. The rotation center A1 of the rod 620 may be located closer to the front face 20a of the door 20 than the second member 534.

[0193] When the door 20 is closed, the first member 532 may contact the end 421 a of the first portion 421 .

[0194] When the door 20 is closed, the contact portion 622 of the rod 620 may contact the third contact surface 543 .

[0195] When the door 20 starts to open in a closed state, the door 20 may rotate in one direction (direction D1 ) based on the first rotation center C1 .

[0196] When the door 20 is closed, the end 421 a of the first portion 421 or the first member 532 may be located closer to the front surface 10 a of the housing 10 than the first rotation center C1 .

[0197] In the present specification, the rotation center of the door 20 may be a virtual rotation center of the door 20. The virtual rotation center of the door 20 may be a virtual rotation center of the guide portion 530.

[0198] The first rotation center C1 may be located at the door 20. For example, the first rotation center C1 may be located at a position further back than the front surface 20a of the door 20.

[0199] In this manual, the rear direction refers to the direction from the door to the cabinet, and the front direction refers to the direction from the cabinet to the door.

[0200] The door 20 may include two side surfaces, and the two side surfaces may include a first side surface 20c adjacent to the hinge bracket 50 and a second side surface 20d located on the opposite side of the first side surface 20c.

[0201] When the refrigerator 1 is located in a furniture cabinet P, the first side surface 20c of the refrigerator 1 needs to be arranged adjacent to the furniture cabinet P, and interference between the door 20 and the furniture cabinet P needs to be prevented during the rotation of the door 20 .

[0202] In this embodiment, preferably, the first rotation center C1 is adjacent to the first side surface 20c.

[0203] Reference Figure 8 (b), when the door 20 is rotated by the first angle, the door 20 can rotate with the second rotation center C2 as a reference. That is, during the process of the door 20 opening the first angle, the rotation center of the door 20 can move. The second rotation center C2 can be located at the door 20.

[0204] The second rotation center C2 may be located closer to the front surface 10 a of the box body 10 than the first rotation center C1 .

[0205] When the door 20 is rotated by the first angle, the guide portion 530 may be located at the first portion 421 .

[0206] When the door 20 is rotated by the first angle, the contact portion 622 of the rod 620 may contact the second contact surface 542 .

[0207] When the door 20 is rotated by the first angle, the second rotation center C2 may be located closer to the front face 10a of the box body 10 than the end 421a of the first portion 421. When the door 20 is rotated by the first angle, the first member 532 may be located closer to the front face 10a of the box body 10 than the second rotation center C2.

[0208] As the rotation center of the door 20 moves, the curvature of the first portion 421 may vary to prevent interference between the first and second members 532 and 534 of the first portion 421 and the door bracket 40 .

[0209] Reference Fig. 9 (a), when the door 20 is rotated by a second angle greater than the first angle, the door 20 can rotate with the third rotation center C3 as a reference.

[0210] When the door 20 is opened to the second angle, the rotation center of the door 20 may move. The third rotation center C3 may be located at the door 20 .

[0211] The third rotation center C3 may be located closer to the front surface 10 a of the box body 10 than the second rotation center C2 .

[0212] When the door 20 rotates the second angle, the first member 532 may be located at the first portion 421 , and at least a portion of the second member 534 may be located at the first portion 421 . At this time, a portion of the second portion 422 may be located at the boundary portion 423 .

[0213] When the door 20 is rotated by the second angle, the contact portion 622 of the lever 620 may contact the first contact surface 541 or a boundary between the first contact surface 541 and the second contact surface 542 .

[0214] When the door 20 is rotated by the second angle, the third rotation center C3 may be located closer to the front surface 10 a of the housing 10 than the end 421 a of the first portion 421 .

[0215] Reference Fig. 9 (b) In a state where the door 20 is rotated by a third angle greater than the second angle, the door 20 may be rotated with the fourth rotation center C4 as a reference.

[0216] When the door 20 is opened to the third angle, the rotation center of the door 20 may move. The fourth rotation center C4 may be located at the door 20 .

[0217] The fourth rotation center C4 may be located closer to the front surface 10 a of the box body 10 than the third rotation center C3 .

[0218] When the door 20 is rotated by the third angle, the first member 532 may be located at the first portion 421 , and at least a portion of the second member 534 may be located at the second portion 422 .

[0219] When the door 20 is rotated by the third angle, the contact portion 622 of the rod 620 may be spaced apart from the first contact surface 541 .

[0220] Reference Fig.10 Before the door 20 is about to open to the maximum opening angle, the door 20 can rotate with the fifth rotation center C5 as a reference.

[0221] The fifth rotation center C5 may be located at the door 20. The fifth rotation center C5 may be located closer to the front surface 10a of the box body 10 than the fourth rotation center C4.

[0222] When the door 20 is rotated to the maximum opening angle, the first member 532 and the second member 534 may be located in the second portion 422 .

[0223] When the door 20 is rotated to the maximum opening angle, the second member 534 may contact the other end 422a of the second portion 422. Therefore, the other end 422a of the second portion 422 may function as a stopper for limiting the rotation of the door.

[0224] In this specification, the interval in which the door is opened to the second angle (reference angle) when the door is closed may be referred to as the first door opening interval. The interval in which the door is opened from the second angle (reference angle) to the maximum opening angle may be referred to as the second door opening interval. That is, at the end of the second door opening interval, the door may be opened to the maximum opening angle.

[0225] In the first door opening section, the rotation center of the door 20 may be changed from the first rotation center to the third rotation center. In the second door opening section, the rotation center of the door 20 may be changed from the third rotation center to the fifth rotation center.

[0226] A door opening angle of the first door opening section may be smaller than a door opening angle of the second door opening section.

[0227] A movement variation of the rotation center in the X-axis direction during the first door opening section may be greater than a movement variation of the rotation center in the X-axis direction during the second door opening section.

[0228] A movement variation of the rotation center in the Y-axis direction during the first door opening section may be smaller than a movement variation of the rotation center in the Y-axis direction during the second door opening section.

[0229] The rotation center C3 of the door 20 after the first door opening interval is closer to the first side surface 20c of the door 20 than the rotation center C5 of the door 20 after the second door opening interval is completed. That is, the rotation center of the door 20 can move away from the furniture cabinet P throughout the door opening interval.

[0230] In the entire opening range of the door, the rotation center of the door 20 may be located outside the guide portion 530. In the entire opening range of the door, the rotation center of the door 20 may be located outside the receiving portion 420.

[0231] In the entire opening range of the door, the rotation center of the door 20 may be spaced apart from the guide portion 530. In the entire opening range of the door, the rotation center of the door 20 may be located at a position farther from the front surface 10a of the housing 10 than the first member 532.

[0232] The process of closing the door 20 is briefly described.

[0233] After the door 20 is opened to an angle below the maximum opening angle, the door 20 may be rotated in the other direction and closed.

[0234] Reference Fig. 9 (b) When the door 20 is closed, the contact portion 622 of the rod 620 may contact the first contact surface 541 .

[0235] During the closing process of the door 20 , after the contact portion 622 of the rod 620 contacts the first contact surface 541 , if the door 20 is further closed, the rod 620 may rotate in the first direction in which the elastic force is accumulated.

[0236] During the closing process of the door 20 , the contact portion 622 of the rod 620 moves along the first contact surface 541 , and the elastic force accumulated by the rod 620 may increase.

[0237] In the process of further closing the door 20 , the contact portion 622 of the rod 620 may be spaced apart from the first contact surface 541 and contact the second contact surface 542 .

[0238] When the contact portion 622 of the rod 620 is in contact with the second contact surface 542, if the door 20 is further rotated in the closing direction, the rod 620 is rotated in the second direction opposite to the first direction under the action of the elastic force accumulated in the rod 620, so that the door 20 can be automatically closed. The elastic force accumulated in the rod 620 can act as an automatic closing force for the door 20.

[0239] In the first door opening interval (or the first door closing interval), the automatic closing device 60 can be used to provide a door closing force.

[0240] From the perspective of the automatic closing device 60, during the closing process of the door 20, the distance between the rotation center A1 of the rod 620 and the rotation center of the door 20 may be changed.

[0244] Figures 11 to 13 This is a picture of the door bracket and hinge bracket viewed from the bottom side of the refrigerator.

[0245] In this embodiment, the only difference from the first embodiment is that the shape rotation center of the door relative to the accommodating portion is moved and changed, and the other parts are the same as the first embodiment. Therefore, only the characteristic parts of this embodiment are described below.

[0246] Reference Figures 11 to 13 The door 25 of this embodiment may include a receiving portion 440. A guide portion of the hinge bracket may be received in the receiving portion 440.

[0253] When the door 25 is closed and starts to open, the door 25 may rotate in one direction based on a first rotation center C1 . The first rotation center C1 may be located at the door 25 .

[0254] Reference Fig.11 (b), when the door 25 is rotated by the first angle, the door 25 can rotate with the second rotation center C2 as a reference. That is, during the process of the door 20 opening the first angle, the rotation center of the door 25 can move. The second rotation center C2 can be located outside the door 25.

[0255] The first rotation center C1 may be located closer to the front surface 10 a of the housing 10 than the second rotation center C2 .

[0275] In the case of the present embodiment, the rotation center of the door 25 can move in a direction away from the front surface 10 a of the housing 10 in a partial section of the entire opening section of the door.

[0276] In another part of the entire opening interval of the door, the rotation center of the door 25 can move toward the front side 10a of the box body 10. At the beginning of the entire opening interval, the rotation center of the door 25 can be located behind the door 25, move to the outside of the door 25, and then move back to the door 25.

[0277] In the entire opening interval of the door, the interval in which the rotation center of the door 25 moves in a direction away from the front face 10a of the box body 10 may be referred to as the first door opening interval.

The interval after the second door opening interval may be referred to as the third door opening interval. In the third door opening interval, the rotation center of the door 25 may move in a direction close to the front face 10a of the box body 10.

[0287] In this embodiment, the difference from the second embodiment is only the shape of the guide portion, and the other parts are the same as the second embodiment. Therefore, only the characteristic parts of this embodiment will be described below.

[0288] In addition, during the opening process of the door 25, the moving position and the changing manner of the rotation center are the same as those of the second embodiment, so the description of the second embodiment is cited.

[0289] Reference Figures 14 to 16 The door 25 of this embodiment may include a receiving portion 440. A guide portion 550 of a hinge bracket may be received in the receiving portion 440. The guide portion 550 may be a single component.

[0290] The guide portion 550 may include a first surface 551 and a second surface 552 spaced apart from the first surface 551. The guide portion 550 may further include a third surface 553 connecting one end of the first surface 551 and one end of the second surface 552. The guide portion 550 may further include a fourth surface 554 connecting the other end of the first surface 551 and the other end of the second surface 552.

[0291] The first surface 551 may include a curved surface. The second surface 552 may include a curved surface. The third surface 553 may include a curved surface. The fourth surface 554 may include a curved surface.

[0292] The third surface 553 may include a portion having a greater curvature than that of the fourth surface 554. A portion of the third surface 553 may include a portion that is recessed toward the fourth surface 554.

[0293] When the door 25 is closed, a portion of the guide portion 550 may be located at the first portion 441 , and another portion may be located at the second portion 442 .

[0294] At least a portion of the third surface 553 may be spaced apart from the first portion 441 . At least a portion of the fourth surface 554 may be in contact with the first portion 441 .

[0295] When the door 25 is closed and starts to open, the door 25 may rotate in one direction based on a first rotation center C1 . The first rotation center C1 may be located at the door 25 .

[0296] Reference Fig.16 (b) Before the door 25 is about to open to the maximum opening angle, the door 25 can rotate with the sixth rotation center C6 as a reference. The sixth rotation center C6 can be located at the door 25.

[0297] When the door 25 is rotated to the maximum opening angle, a portion of the guide portion 550 may be located at the third portion 443 , and another portion may be located at the fourth portion 444 .

[0298] In the case of this embodiment, the rotation center of the door 25 can move in a direction away from the front surface 10a of the box body 10 in the entire opening range, and then move in a direction close to it again.

[0300] When the door 25 is opened to the maximum opening angle, the sixth rotation center C6 of the door 25 may be located at a position farther from the front surface 10 a of the box body than the accommodation portion 440 .

[0301] During the opening process of the door, the concave shape of the third surface 553 of the guide portion 550 can prevent the third surface 553 from interfering with the door bracket.

[0304] Fig.17 and Fig.18 It is a figure which observes the hinge bracket from the lower side of the hinge bracket, and a door is omitted.

[0305] In this embodiment, the difference from the previous embodiment is only the shape of the contact surface of the hinge bracket, the form of the guide portion, and the shape of the accommodating portion, while other parts are the same as the previous embodiment.

[0306] Therefore, only the characteristic parts of this embodiment will be described below.

[0307] Reference Fig.17 and Fig.18 The hinge bracket 50A of this embodiment may include a guide portion 730. The guide portion 730 may include a first member 732 (or a first pin) and a second member 734 (or a second pin) separated from each other. The first member 732 and the second member 734 may be referred to as a first guide.

[0308] The door may include a receiving portion 840 (or a guide member) receiving the guide portion 730. The receiving portion 840 may include a slit 841 for receiving the first member 732 and the second member 734 together. The slit 841 may be referred to as a second guide.

[0309] The slit 841 may be formed in a curved shape. The curvature of the slit 841 may be variable. The curvature of the slit 841 may be changed continuously or in stages. Fig.17 and Fig.18 It is shown that the curvature of the slit 841 changes in stages.

[0310] If the curvature of the slit 841 changes in stages, the slit 841 may include a plurality of divided paths 851, 852, 853, 854, 855. That is, the slit 841 may include a plurality of paths 851, 852, 853, 854, 855 extending in different directions or having different curvatures.

[0311] The length of one part of the plurality of paths 851, 852, 853, 854, 855 may be different from the length of another part. The length of the first path 851 may be the largest, and the length of the third path 853 may be the smallest, but is not limited thereto.

[0312] The slit 841 may include a first end portion 841 a. The slit 841 may include a second end portion 841 b located on the opposite side of the first end portion 841 a based on the length of the slit 841 .

[0313] When the door is closed, the first member 732 may be in contact with or close to the first end 841a. When the door is opened to a maximum opening angle, the second member 734 may be in contact with or close to the second end 841b.

[0314] Reference Figure 8 and Fig.17 The first end 841a may be located closer to the front face 20a of the door 20 than the second end 841b. The second end 841b may be located closer to the first side face 20c of the door 20 than the first end 841a.

[0315] Among the plurality of paths 851 , 852 , 853 , 854 , and 855 , the third path 853 may be located close to the front surface 10 a of the housing 10 .

[0316] The hinge bracket 50A may include a contact surface 540 a that interacts with the automatic closing device 70 .

[0317] The contact surface 540a may include a first contact surface 541a. The first contact surface 541a may be a surface that the contact portion 762 of the rod 760 first contacts during the process of closing the door after the door is opened.

[0318] When the door is opened to a setting angle or more, the rod 760 does not contact the first contact surface 541a. When the door is closed to an angle smaller than the setting angle, the rod 760 may contact the first contact surface 541a.

[0319] The first contact surface 541 a may be inclined in a direction closer to the front surface 10 a of the box body 10 and farther away from the guide portion 730 .

[0320] The contact surface 540a may further include a second contact surface 542a extending from the first contact surface 541a. The second contact surface 542a may be arranged to be inclined relative to the first contact surface 541a.

[0321] The second contact surface 542 a may be inclined in a direction closer to the front surface 10 a of the box body 10 and closer to the guide portion 730 .

[0322] When closing the door, the rod 760 provides a closing force to the door while moving along the second contact surface 542a, so that the door can be automatically closed.

[0323] The contact surface 540a may further include a third contact surface 543a extending from the second contact surface 542a. The third contact surface 543a may be arranged to be inclined relative to the second contact surface 542a.

[0324] The third contact surface 543 a may extend from the second contact surface 542 a toward a direction approaching the guide portion 730 .

[0325] The hinge bracket 50A may further include a receiving groove 544 a for receiving a portion of the rod 760 or reducing interference with the rod 760 when the rod 760 is in contact with the third contact surface 543 a .

[0326] Reference Fig.17 (a), when the door is closed, the first member 732 may be located on the first path 851 , and the second member 734 may be located on the second path 852 .

[0327] When the door is closed, the contact portion 762 of the rod 760 contacts the third contact surface 543a. When the door is closed, the rotation angle of the rod 760 may be greater than 0 degrees with respect to the front side of the door. In this case, the elastic force of the elastic member is applied by the rod 760, so that the door can be kept closed.

[0328] On the other hand, if the door begins to open with its center of rotation located at a position that is expected to first contact the furniture cabinet (reference Figure 8 By reducing the corners of the side and front sides of the door that interfere with the furniture cabinet P, interference between the door and the furniture cabinet P can be prevented.

[0329] Therefore, at the moment when the door starts to open, the rotation center of the door can be located adjacent to the corners of the front and side surfaces of the door.

[0330] On the other hand, when the user performs the operation of opening the door, the door can move forward and to one side instantaneously along the direction of the first path 851, so that the door starts to open.

[0331] The first member 732 and the second member 734 are located in the first path 851 and the second path 852 extending in different directions, so that the door is subjected to a rotational force based on a rotation operation to accurately realize the opening action of the door without distortion or slippage.

[0332] When the second member 734 moves in the second path 852, the door can rotate while slightly moving forward and to one side, so the gasket G that is in close contact with the front surface of the box body 10 can be separated more easily. That is, interference caused by the gasket G that is in close contact with the box body 10 when the door rotates can be prevented, and the subsequent rotation of the door can be smoother.

[0333] Reference Fig.17 (b), when the door is rotated by a first angle, the contact portion 762 of the rod 760 may be located at the boundary between the second contact surface 542a and the third contact surface 543a. When the door is rotated by a first angle, the first member 732 may be located at the first path 851, and the second member 734 may be located at the second path 852.

[0334] Reference Fig.17(c), when the door is rotated by a second angle greater than the first angle, the contact portion 762 of the rod 760 may contact the second contact surface 542a. When the door is rotated by the second angle, the first member 732 may be located on the first path 851, and the second member 734 may be located on the second path 852 or on the boundary between the second path 852 and the third path 853.

[0335] Reference Fig.18 (a), when the door rotates to a third angle greater than the second angle, the contact portion 762 of the rod 760 may contact the second contact surface 542a. When the door rotates to the third angle, the first member 732 may be located on the first path 851, and the second member 734 may be located on the third path 853.

[0336] Reference Fig.18 (b), when the door is rotated to a fourth angle greater than the third angle, the contact portion 762 of the rod 760 may contact the second contact surface 542a. When the door is rotated to the fourth angle, the first member 732 may be located in the first path 851, and the second member 734 may be located in the third path 853.

[0337] Reference Fig.18 (c), when the door is rotated to a fifth angle (reference angle) greater than the fourth angle, the contact portion 762 of the rod 760 may be located at the boundary between the first contact surface 541a and the second contact surface 542a. When the door is rotated to the fifth angle, the rotation angle of the rod 760 may be the maximum with the front face of the door as a reference. That is, the rotation angle of the rod 760 may increase with the front face of the door as a reference until the door is rotated from the closed state to the fifth angle.

[0338] When the door is rotated to a fifth angle, the first member 732 may be located adjacent to the second path 852 in the first path 851 , and the second member 734 may be located in the third path 853 .

[0339] When the door is opened at an angle greater than the fifth angle, the first member 732 may move toward the second path 852 , and the second member 734 may move toward the fourth path 854 .

[0340] When the door is further opened, the first member 732 may move toward the third path 853 , and the second member 734 may move along the fourth path 854 .

[0341] When the door is further opened, the first member 732 may move toward the fourth path 854 , and the second member 734 may move toward the fifth path 855 .

[0342] When the door is opened to the maximum opening angle, the angle between the front of the box body 10 and the back of the door may be approximately 110°. At this time, the first member 732 may move along the fourth path 854, and the second member 734 may move to the end of the fifth path 855. The center of curvature of each of the plurality of paths is different from each other, so during the opening process of the door, the imaginary rotation center of the door will move, thereby having the advantages of not interfering with the furniture cabinet and being able to ensure the opening angle of the door.

[0343] During the closing process of the door, at the time point when the door rotates to the fifth angle, the closing force of the automatic closing device 70 may act on the door. During the continuous closing process of the door, as the rotation angle of the rod 760 decreases, the elastic force may act on the door.

[0344] Fig.19 1 is a diagram showing the configuration of a door and a furniture cabinet of a fifth embodiment, Fig. 20 is a diagram showing the arrangement of slits and a pin unit of the fifth embodiment. Fig.21 1 is a diagram showing an angle of a tangent line to the first path and an angle of a tangent line to the second path with reference to a boundary point between the first path and the second path according to the fifth embodiment.

[0345] In this embodiment, the difference from any one of the first to fourth embodiments is only the shape of the slit and the relative positions of the first component and the second component located in the slit, and the other parts are the same as any one of the first to fourth embodiments.

[0346] Therefore, only the characteristic parts of this embodiment will be described below.

[0347] Reference Figures 19 to 21 The door 20 of this embodiment is as described in the above-mentioned embodiment, and the rotation of the door 20 can be guided by the guide portion provided on the hinge bracket.

[0348] The guide portion may include a first member 931 (or a first pin) and a second member 932 (or a second pin) that are spaced apart from each other. The first member 931 and the second member 932 may be referred to as a first guide.

[0349] The door 20 may include a slit 941 accommodating the first member 931 and the second member 932. The slit 941 may be referred to as a second guide.

[0350] The door 20 may be disposed adjacent to the cabinet P. The refrigerator may be accommodated in the cabinet P. It is preferable to minimize the interval D2 between the first side surface 20c of the door 20 and a side wall of the cabinet P. In addition, while minimizing the interval D2, it is necessary to prevent the door 20 from interfering with the cabinet P when the door 20 is opened.

[0351] In this embodiment, the slit 941 may be designed to minimize the interval D2 while preventing the door 20 from interfering with the furniture cabinet P when the door 20 is opened.

[0352] A corner 20d connecting the front surface 20a and the first side surface 20c of the door 20 may be arc-shaped to prevent the door 20 from interfering with the furniture cabinet P when the door 20 is opened.

[0353] The slit 941 may include a first end portion 941 a. The slit 941 may include a second end portion 941 b located on the opposite side of the first end portion 941 a based on the length of the slit 941 .

[0354] When the door 20 is closed, the first member 931 may be in contact with or close to the first end 941a. When the door 20 is opened to a maximum opening angle, the second member 932 may be in contact with or close to the second end 941b.

[0355] The second end portion 941b may be located closer to the first side surface 20c of the door 20 than the first end portion 941a. The first side surface 20c refers to a side surface of the door 20 adjacent to the furniture cabinet P and the slit 941.

[0356] When the door 20 is closed, the first end portion 941 a may be located closer to the front surface 20 a of the door 20 than the second end portion 941 b .

[0357] The slit 941 may be formed in a curved shape. The curvature of the slit 941 may be variable. The curvature of the slit 941 may be changed continuously or in stages. Fig. 20 It is shown that the curvature of the slit 941 changes in stages.

[0358] If the curvature of the slit 941 changes in stages, the slit 941 may include a plurality of divided paths 951, 952, 953, 954, 955. That is, the slit 941 may include a plurality of paths 951, 952, 953, 954, 955 extending in different directions or having different curvatures.

[0359] The length of a portion of the plurality of paths 951 , 952 , 953 , 954 , 955 may be different from the length of another portion.

[0360] The length of the first path 951 may be greater than the length of the second path 952. The length of the first path 951 may be greater than the length of the third path 953. The length of the second path 952 may be greater than the length of the third path 953.

[0361] Among the plurality of paths 951 , 952 , 953 , 954 , and 955 , the length of the first path 951 may be the largest.

[0362] With the door 20 being closed as a reference, the center RC1 of the curvature of the first path 951 may be located on the door 20 .

[0363] With the door 20 closed, the center RC2 of the curvature of the second path 952 may be located outside the door 20. For example, the center RC2 may be located further forward than the front surface 20a of the door 20. The center RC2 may be located closer to the first side surface 20c of the door 20 than the center RC1.

[0364] With the door 20 closed as a reference, the center RC3 of the curvature of the third path 953 may be located outside the door 20. As an example, the center RC3 may be located further forward than the front surface 20a of the door 20. The center RC2 may be located closer to the first side surface 20c of the door 20 than the center RC3.

[0365] With the door 20 closed as a reference, the center RC4 of the curvature of the fourth path 954 may be located at the door 20. As an example, the center RC4 may be located closer to the first end 941a than the second end 941b. The center RC4 may be located closer to the back surface 20b of the door 20 than the center RC1.

[0366] With the door 20 closed as a reference, the center RC5 of the curvature of the fifth path 955 may be located at the door 20. As an example, the center RC4 may be located closer to the first side surface 20c of the door 20 than the center RC5. The center RC5 may be located closer to the back surface 20b of the door 20 than the center RC4. The first end 941a may be located closer to the first side surface 20c of the door 20 than the center RC5.

[0367] With the door 20 closed as a reference, a line connecting the center RC5 of the curvature of the fifth path 955 and a position of the fifth path 955 may pass through an area between the first end 941a and the boundary point BP in the slit 941. The slit 941 may be located between the second end 941b and the center RC5 of the curvature of the fifth path 955.

[0368] Reference Fig.21 When the position where the first path 951 and the second path 952 intersect is called the boundary point BP, the angle formed by the first line passing through the boundary point BP and in contact with the first path 951 and the reference line passing through the boundary point BP and parallel to the front side 20a or the back side 20b of the door 20 can be called the first angle A1.

[0369] The angle formed by the second line passing through the boundary point BP and contacting the second path 952 and the reference line passing through the boundary point BP may be referred to as a second angle A2.

[0370] At this time, the first angle A1 may be greater than the second angle A2.

[0371] The first angle A1 may affect the interval between the door 20 and the furniture cabinet P when the door 20 is opened.

[0372] The first angle A1 may be greater than or equal to 40 degrees and less than or equal to 45 degrees.

[0373] If the first angle A1 is greater than 45 degrees, there is a risk that the door 20 interferes with the furniture cabinet P during the opening of the door 20. On the contrary, if the first angle A1 is less than 40 degrees, there is a risk that one door (or a trim panel of one door) interferes with another door when one of the doors arranged on both sides is opened.

[0374] The difference between the first angle A1 and the second angle A2 can be adjusted by adjusting the gasket (see Fig. 22 G) and the relationship between the box 10.

[0375] The difference may be greater than 2 degrees and less than 5 degrees. If the difference is greater than 5 degrees, there is a risk that the amount of interference between the gasket G and the housing 10 increases when the door 20 is initially opened, thereby increasing the amount of wear on the gasket G.

[0376] On the contrary, if the difference is less than 2 degrees, there is a risk that the door 20 may slide during the opening process of the door 20, so that the door 20 may not rotate smoothly.

[0377] The length of the second path 952 may be greater than the length of the third path 953. The length of the third path 953 may be greater than the length of the fourth path 954. The length of the fifth path 955 may be greater than the length of the fourth path 954.

[0378] The third path 953 may be closest to the rear surface 20 b of the door 20 , but is not limited thereto.

[0379] A distance between a bisecting position that bisects the length of the third path 953 and the first end 941 a may be greater than a distance between the bisecting position and the second end 941 b .

[0380] Fig. 22 It is a diagram showing the positional relationship between the opening and the slit when the opening is formed in the door of the fifth embodiment.

[0381] Reference Fig.19 and Fig. 22 In the present embodiment, the door 20 may be provided with an opening 960 at a position adjacent to the slit 941. As an example, the opening 960 may allow one or more of a water pipe through which water flows and a wire connected to a component provided on the door 20 to pass.

[0382] Fig. 22 The maximum size of the opening 960 that can be formed in the door 20 is shown, and the size of the opening 960 may vary.

[0383] It should be noted that in Fig. 22 In the figure, the position of the opening 960 is exemplary, and the position of the opening 960 may also be changed.

[0384] In one embodiment, a portion of the opening 960 may overlap with an imaginary connecting line connecting the first end 941a and the second end 941b of the slit 941. That is, a portion of the opening 960 may be located in a region between the first end 941a and the second end 941b that are separated from each other.

[0385] A portion of the opening 960 may be located closer to the rear surface 20 b of the door 20 than the first end 941 a and the second end 941 b .

[0386] Another portion of the opening 960 may be located closer to the front surface 20 a of the door 20 than the first end portion 941 a and the second end portion 941 b .

[0387] On the other hand, the slit 941 may be disposed in a region indicated by a dotted line in the door 20. That is, the slit 941 may be disposed in a region that does not interfere with a structure provided or coupled to the door 20.

[0388] A minimum distance between the back surface 20 b of the door 20 and the slit 941 may be greater than a minimum distance between the front surface 20 a of the door 20 and the first end 941 a .

[0389] A minimum distance between the back surface 20 b of the door 20 and the slit 941 may be greater than a minimum distance between the front surface 20 a of the door 20 and the second end portion 941 b .

[0390] A minimum distance between the first side surface 20 c of the door 20 and the slit 941 may be smaller than a minimum distance between the front surface 20 a of the door 20 and the first end portion 941 a .

[0391] Figure 23 to Figure 25 It is a diagram showing the positions of the door and the furniture cabinet when the door of the fifth embodiment is open. Fig.26 and Fig. 27 It is a diagram showing a virtual rotation center of the door when the door is open according to the fifth embodiment.

[0392] Fig.23 (a) shows the state where the door is closed, Fig.23 (b) shows the state where the door is opened to a first angle, Fig.24 (a) shows the state where the door is opened to a second angle, Fig.24 (b) shows the state where the door is opened to a third angle, Fig.25 The state of the door opening to the maximum opening angle is shown.

[0393] Reference Figure 22 to Figure 25 , a line extending along the first side surface 20 c of the door 20 when the door 20 is closed may be referred to as an imaginary line IL1 .

[0394] In the case of this embodiment, when the door 20 is opened using the slit 941, the door 20 may not move to the space between the imaginary line IL1 and the cabinet P. Therefore, even if the refrigerator is configured such that the interval D2 between the first side surface 20c of the door 20 and the cabinet P is close to 0, the door 20 may be opened without interfering with the cabinet P during the opening process of the door 20.

[0395] In this embodiment, when the slit 941 is designed so that the first end 941 a and the second end 941 b are far apart, the interval D2 can be reduced.

[0396] For example, assuming that the position of the second end portion 941b is fixed, the interval D2 may be smaller when the distance between the first end portion 941a and the second end portion 941b is large compared to when the distance between the first end portion 941a and the second end portion 941b is small.

[0397] In order to increase the distance between the first end 941 a and the second end 941 b , the curvature of at least one of the first path to the third path 951 , 952 , and 953 of the slit 941 may be reduced.

[0398] On the other hand, refer to Fig.19 , Fig.26 as well as Fig. 27 The slit 941 includes a plurality of paths 951, 952, 953, 954, and 955, and the center of curvature of each of the plurality of paths 951, 952, 953, 954, and 955 may be located at different positions.

[0399] When the door 20 rotates in a state in which the positions of the first member 931 and the second member 932 are fixed, the positions of the plurality of paths 951 , 952 , 953 , 954 , and 955 may be changed.

[0400] The center of curvature of each of the plurality of paths 951 , 952 , 953 , 954 , 955 is different from each other, so during the rotation of the door 20 , the center of curvature of each of the plurality of paths 951 , 952 , 953 , 954 , 955 may also move.

[0401] During the rotation of the door 20, the relative positions of the first member 931 and the second member 932 and the plurality of paths 951, 952, 953, 954, 955 can be changed, so during the rotation of the door 20, the center of curvature of a path where the first member 931 and the second member 932 are located or correspond to can become the rotation center of the door 20. Alternatively, the rotation center of the door 20 can be located on a line connecting the centers of curvature of two adjacent paths.

[0402] For example, when the first member 931 and the second member 932 are located in the first path 531 , the rotation center C1 of the door is the same as the center of curvature of the first path 531 .

[0403] When the door 20 initially rotates, the door 20 may rotate with the first rotation center C1 as a reference. The first rotation center C1 may be located at the door 20 .

[0418] The fourth rotation center C4 may be located closer to the front surface 10 a of the box body 10 than the fifth rotation center C5 .

[0419] The fourth rotation center C4 may be located closer to the second member 932 than the fifth rotation center C5.

[0421] At this time, the opening angle of the door 20 in the second section may be greater than the opening angle of the door 20 in the first section and the opening angle of the door 20 in the third section.

[0422] When the movement pattern of the imaginary rotation center of the door 20 is observed from the other side, the entire opening range of the door 20 may include a first range where the imaginary rotation center is away from the first member (or the second member), a second range close to the first member (or the second member), and a third range away from the first member (or the second member).
