Description

refrigerator

[0001] The present invention relates to a refrigerator capable of adjusting the step of a door.

[0002] A refrigerator is a home appliance that supplies cold air generated by the circulation of refrigerant to a storage room, thereby keeping various types of storage objects fresh for a long period of time.

[0003] A refrigerator may include a cabinet including one or more storage compartments, and a plurality of doors arranged on the front of the cabinet to open and close the storage compartments.

[0004] When multiple doors are placed on the front of the cabinet, the multiple doors may be installed with different degrees of protrusion in the front-back direction.

[0005] In this case, when multiple doors are installed with different degrees of protrusion in the forward and backward directions, a step difference in the forward and backward directions may occur between the doors.

[0006] These step defects can be caused by various reasons, such as slight dispersion of the door product itself that can occur during the refrigerator manufacturing process, or assembly tolerances between the cabinet and the door.

[0007] If there is a gap between multiple doors, it not only damages the aesthetics of the refrigerator, but can also lead to a defect in the appearance of the refrigerator.

[0008] In order to eliminate the step difference in the front-back direction between each door, a step adjustment member may be formed between the cabinet and the door, and a method of adjusting the step difference between the doors through the step adjustment member may be used.

[0009] For example, a step adjustment member for adjusting the step between the cabinet and the door can be installed near the center area of ​​the back surface of the door.

[0010] In this case, the step adjustment member can be adjusted to move forward and backward in the forward and backward direction, thereby compensating for the step difference in the forward and backward direction between the cabinet and the door.

[0011] However, when the step adjustment member is placed between the door and the cabinet, i.e. in the area where the step occurs, the following problems arise.

[0012] First, since the back surface of the door, which is extended in the left-right direction, is pressed by the step adjustment member, a bending phenomenon may occur in which the back surface of the door bends in the left-right direction around the pressed area.

[0013] Accordingly, a problem may arise where the back of the door is further deformed by the step adjustment member.

[0014] Additionally, as the step adjustment member is placed in the step generation area, the reference position at which the step is adjusted by the step adjustment member may also change.

[0015] That is, since the step adjustment member is located in an area where a large dimensional variation occurs and where dimensional control due to deformation is difficult, a problem may arise where the step adjustment member does not function properly as the amount of adjustment by the step adjustment member is offset when the door is deformed significantly.

[0016] In addition, when the step adjustment member is placed on the back of the door, there is a problem in that the aesthetic appeal of the door is reduced and the user's usability is reduced because the user can immediately recognize the step adjustment member when the door is opened.

[0017] An object of the present invention is to provide a refrigerator capable of reducing the step adjustment effect from being reduced due to the step adjustment amount of a step adjustment member being offset when the door is deformed significantly.

[0018] In addition, it is an object of the present invention to provide a refrigerator capable of reducing deformation or warping of the back surface of a door due to pressure from a step adjustment member.

[0019] Another object of the present invention is to provide a refrigerator capable of finely adjusting the step distance.

[0020] In addition, it is an object of the present invention to provide a refrigerator in which the step adjustment member is positioned so as not to be easily exposed to the user even when the door is opened, thereby improving the appearance quality of the door.

[0021] The objectives of the present invention are not limited to those mentioned above. Other objectives and advantages of the present invention not mentioned above can be understood through the following description and will be more clearly understood through the embodiments of the present invention. Furthermore, it will be readily apparent that the objectives and advantages of the present invention can be realized by the means and combinations thereof set forth in the claims.

[0022] According to one embodiment of the present invention for solving the above-described problem, a refrigerator includes a cabinet including one or more storage compartments, one or more doors for opening and closing the storage compartments, and a hinge assembly connected to the door and the cabinet so that the door can rotate from the cabinet, and the hinge assembly includes a step adjustment member for adjusting a distance in the front-rear direction between the door and the cabinet.

[0023] The above step adjustment member is arranged on one side of the door and can be adjusted to selectively pressurize the door.

[0024] The above door includes a pressure surface that is pressed by the step adjustment member, and the pressure surface can be located at the rear of the door.

[0025] The above pressure surface may be formed as an inclined surface.

[0026] The step adjustment member presses the rear surface of the pressing surface, and the pressing surface can be inclined so that the front surface of the pressing surface faces the front surface of the door and the other side of the door.

[0027] The above step adjustment member can be in surface contact with the pressurized surface.

[0028] The direction of action of the force that presses the pressure surface by the step adjustment member may be orthogonal to the direction in which the pressure surface extends.

[0029] One of the above doors includes a main door and a sub-door positioned at the front of the main door and rotatably connected from the main door, and the pressurized surface may be included in the main door.

[0030] The above step adjustment member can be fastened to the hinge assembly in a screw-joint manner.

[0031] The hinge assembly includes a door coupling portion connected to the door and a cabinet coupling portion connected to the cabinet, and the step adjustment member can be fastened to one side of the door coupling portion.

[0032] The door joint includes a support portion bent in an upper direction of the door joint portion, the support portion includes a fastening hole opened toward the door, and the step adjustment member can be fastened to the fastening hole.

[0033] The step adjustment member includes a fastening portion and a pressing portion connected to one side of the fastening portion, and the fastening portion can be fastened to the fastening hole so that the pressing portion faces the door.

[0034] The above pressurizing member may include an elastic material.

[0035] A fixing groove may be formed at one end of the above-mentioned fastening portion, and a protruding pattern may be formed on the inside of the above-mentioned pressing portion to be inserted into the fixing groove.

[0036] The step adjustment member further includes a nut member connected to the other side of the fastening portion, and the support member can be arranged between the pressing portion and the nut member.

[0037] The hinge assembly further includes a hinge cover covering at least a portion of the upper surface, and the step adjustment member can be fastened to the hinge cover.

[0038] In addition, according to another embodiment of the present invention for solving the above-described problem, a refrigerator includes a cabinet including one or more storage compartments, a first door and a second door for opening and closing the storage compartments, a first hinge assembly connected to the cabinet and the first door so that the first door can rotate from the cabinet, and a second hinge assembly connected to the cabinet and the second door so that the second door can rotate relative to the cabinet, and the first hinge assembly and the second hinge assembly each include a first door step adjustment member for adjusting a front-back distance between the first door and the cabinet, and a second door step adjustment member for adjusting a front-back distance between the second door and the cabinet.

[0039] The first door step adjustment member and the second door step adjustment member are respectively fastened to the first hinge assembly and the second hinge assembly so that the distance between the first door and the second door can be adjusted in a rotational manner.

[0040] A first extension line extending along the direction of movement of the first door step adjustment member that moves in a rotational manner and a second extension line extending along the direction of movement of the second door step adjustment member that moves in a rotational manner may intersect each other.

[0041] The above first door and the above second door can be opened and closed in a manner in which the center of rotation changes.

[0042] In the refrigerator according to the present invention, since a step adjustment member for adjusting the distance in the front-rear direction between the door and the cabinet is included in the hinge assembly, the step adjustment can be performed in an area of ​​the hinge assembly where the dimensional change due to deformation is small.

[0043] In this way, since the step adjustment member is placed in a hinge assembly with high dimensional stability, away from the step generation area, the adjustment amount of the step adjustment member is hardly offset even when the door is significantly deformed, thereby increasing the usability of the step adjustment member and improving the step adjustment effect.

[0044] In addition, the refrigerator according to the present invention can adjust the door step while minimizing the occurrence of a warping phenomenon in which the back surface of the door is deformed and bent by the step adjustment member because the step adjustment member does not pressurize the back surface of the door that extends in the left-right direction, but pressurizes the pressing surface located on one side of the door adjacent to the hinge assembly.

[0045] In addition, the refrigerator according to the present invention is capable of improving the quality of door step adjustment by allowing linear fine adjustment rather than stepwise adjustment of the step distance since the step adjustment member is fastened to the hinge assembly in a screw-joint manner so that it can move forward and backward in a rotational manner.

[0046] In addition, since the refrigerator according to the present invention is arranged so that the step adjustment member is included in the hinge assembly located on one side of the door, the step adjustment member is not easily exposed to the user even when the door is opened, thereby improving the appearance quality of the door and enhancing the usability of the user.

[0071] Hereinafter, a refrigerator according to some embodiments of the present invention will be described.

[0072] First, referring to FIGS. 1 to 3, a refrigerator, a hinge assembly, and the connection relationship of each of the main components constituting the same according to one embodiment of the present invention will be described.

[0073] A refrigerator (1) may have an exterior formed by a cabinet (2) including one or more storage rooms, which are storage spaces for products, inside, and one or more doors that can open and close the open front of the cabinet (2).

[0074] The cabinet (2) may include an outer case forming the outer surface of the refrigerator (1) and an inner case forming the inner surface.

[0075] The outer case and the inner case are formed to have a space separated from each other, and the space separated can be filled with insulation to form a foaming area.

[0076] The interior of the inner case may be divided into one or more storage spaces.

[0077] The inner case may include one or more storage compartments, for example, if multiple storage compartments are provided, it may include a first storage compartment (3) and a second storage compartment (4) arranged in a vertical direction.

[0078] For example, the first storage compartment (3) located at the top may be a refrigerator compartment, and the second storage compartment (4) located at the bottom may be a freezer compartment.

[0079] However, the positions of the first storage room (3) and the second storage room (4) are not limited thereto, and in other embodiments, the positions of the first storage room (3) and the second storage room (4) may be swapped with each other, and may be arranged parallel to each other in the left-right direction.

[0080] For example, the first storage room (3) can be opened and closed by the first door (10) and the second door (20) which are arranged parallel to each other in the left and right directions.

[0081] Based on the front direction of the refrigerator (1), the first door (10) can be placed on the right side and the second door (20) can be placed on the left side.

[0082] For example, the first door (10) may be configured with a main door (100) and a sub door (110) so that it can be opened and closed in two ways.

[0083] The main door (100) is positioned on the inside to open and close the first storage room (3), and the sub door (110) is rotatably connected to one side of the main door (100) to open and close the front of the main door (100).

[0084] A viewing part (13) is formed on the front of the sub door (110), so that the user can check the inside of the first storage room (3) without opening the first door (10).

[0085] A dispenser (21) that can dispense water or ice without opening the door can be placed on the second door (20).

[0086] The first door (10) and the second door (20) can be arranged to be connected to the cabinet (2) so as to be rotatable from the cabinet (2) by hinge assemblies (50) arranged on one side and the other side of the cabinet (2), respectively.

[0087] Additionally, the second storage room (4) can be opened and closed by the third door (30) and the fourth door (40) which are arranged parallel to each other in the left and right directions.

[0088] Based on the front direction of the refrigerator (1), the third door (30) can be placed on the right side and the fourth door (40) can be placed on the left side.

[0089] Additionally, the third door (30) and the fourth door (40) can also be arranged to be connected to the cabinet (2) so as to be rotatable from the cabinet (2) by hinge assemblies (50) arranged on one side and the other side of the cabinet (2), respectively.

[0090] Hereinafter, a hinge assembly (50) connected to the first door (10) will be described as an example, and a hinge assembly (50) of the same structure or a hinge assembly (50) of a structure with the left and right shapes changed can be placed on the second door (20), the third door, and the fourth door (40), so a detailed description of the hinge assembly (50) placed on the other doors will be omitted.

[0091] A rear frame (101) is arranged on the rear of the first door (10) so that the rear of the first door (10) is finished, a pair of side frames (102) are arranged on both sides of the rear frame (101) so that both sides of the first door (10) are finished, and a cap deco (103) is arranged on the upper surface of the first door (10) so that the upper surface of the first door (10) can be finished.

[0092] Additionally, a front frame is placed on the front of the first door (10) so that the front of the first door (10) can be finished.

[0093] When the first door (10) is divided into a main door (100) and a sub door (110), the front of the first door (10) can be closed by the sub door (110).

[0094] In addition, when the first door (10) is divided into a main door (100) and a sub door (110), the upper surface of the main door (100) and the upper surface of the sub door (110) can each be finished by a separate cap deco (103).

[0095] In addition, when the first door (10) is divided into a main door (100) and a sub door (110), the side of the main door (100) and the side of the sub door (110) may be closed by separate side frames (102), but this is not limited to the case, and the side of the main door (100) and the side of the sub door (110) may share the same side frame (102).

[0096] The first door (10) and the second door (20) can be formed to protrude upwards more than the top surface of the cabinet (2).

[0097] A hinge mounting portion (105) may be formed on one side of the first door (10) adjacent to one side of the upper surface of the cabinet (2) so that a predetermined space is provided in the front direction from the rear and side of the first door (10).

[0098] That is, the hinge mounting portion (105) can be formed at one corner where the rear and side of the first door (10) meet.

[0099] The hinge mounting portion (105) can be formed to extend to the upper surface of the first door (10) to have a predetermined height.

[0100] An opening (104) may be formed in at least a portion of the side frame (102) corresponding to the hinge mounting portion (105).

[0101] An upper cover (14) covering the upper portion of the hinge assembly (50) may be placed on the upper surface of the cabinet (2) located at the rear of the first door (10) and the second door (20).

[0102] For example, the upper cover (14) may be positioned to cover the upper portion of the rear area of ​​the hinge assembly (50).

[0103] Referring to FIG. 3, when the first door (10) is opened, one side of the hinge assembly (50) attached to the first door (10) can pass through the opening (104).

[0104] Additionally, when one side of the hinge assembly (50) is fastened to the hinge mounting portion (105) of the first door (10), the opening (104) can provide the user with the necessary working space.

[0105] The hinge mounting portion (105) can have a space defined by the rear frame (101) of the first door (10) and the side frame (102) of the first door (10).

[0106] A hinge mounting portion (105) is arranged between the rear frame (101) and the side frame (102), and a frame that finishes the outer side of the hinge mounting portion (105) can connect the rear frame (101) and the side frame (102).

[0107] The frame that closes the hinge mounting portion (105) may include a pressure surface (106).

[0108] The pressurized surface (106) may be a surface of the first door (10) that is pressed by the step adjustment member (300) described later.

[0109] The pressure surface (106) is arranged between the rear frame (101) and the side frame (102), and can be arranged to be biased toward one side of the first door (10).

[0110] The pressure surface (106) may be formed as an inclined surface.

[0111] The pressure surface (106) may be a part of the rear frame (101) that constitutes the rear of the main door (100).

[0112] Accordingly, the pressure surface (106) is included in the main door (100) and can be located at the rear of the first door (10).

[0113] For example, the front direction of the refrigerator (1) can be defined as the y-axis, the direction in which the first door (10) extends based on the center of the refrigerator (1) can be defined as the -x-axis, the direction in which the second door (20) extends can be defined as the x-axis, and the direction in which the top surface of the refrigerator (1) can be defined as the z-axis.

[0114] Therefore, the front-back direction of the refrigerator (1) or the front-back direction of the first door (10) and the second door (20) may refer to the y-axis direction, and the left-right direction of the refrigerator (1) or the left-right direction of the first door (10) and the second door (20) may refer to the directions of the -x-axis and the x-axis.

[0115] Based on the direction axis defined in this way, the pressure surface (106) can be formed to extend in the direction between the y-axis and the -x-axis.

[0116] Therefore, in this specification, the fact that the pressure surface (106) has an inclined surface means that it does not have a surface that extends in the same direction as the front-back and left-right directions of the refrigerator (1), but rather has a surface that extends so as to pass between the front-back and left-right directions of the refrigerator (1).

[0117] That is, the pressure surface (106) may be formed to extend obliquely rather than in the same direction as the front-back and left-right directions of the refrigerator (1).

[0118] Accordingly, the pressing surface (106) of the hinge mounting portion (105) formed on the second door (20) can be formed to extend in the direction between the y-axis and the x-axis.

[0119] In other words, the pressure surface (106) arranged to be biased toward one side of the first door (10) can be inclined so that the front of the pressure surface (106) faces the front of the first door (10) and the other side of the first door (10).

[0120] The rear frame (101) is formed to have a length that is longer than the side frame (102), and can be formed to have a length that is longer than the pressure surface (106).

[0121] Meanwhile, a hinge assembly (50) that enables the first door (10) to rotate rotatably from the cabinet (2) can be mounted on the hinge mounting portion (105) formed in this manner.

[0122] The hinge assembly (50) may include a hinge bracket (200) that is fastened to the upper surface of the first door (10) exposed by the hinge mounting portion (105) on one side and fastened to the upper surface of the cabinet (2) on the other side.

[0123] Additionally, the hinge assembly (50) may include a step adjustment member (300) that adjusts the distance in the front-rear direction between the first door (10) and the cabinet (2).

[0124] The step adjustment member (300) can be fastened to the hinge bracket (200).

[0125] Additionally, the hinge assembly (50) may further include a restraining lever (250) mounted so that the other side of the hinge bracket (200) can be maintained in a state of being fastened to the upper surface of the cabinet (2).

[0126] Hereinafter, various embodiments of the hinge assembly (50) according to the present invention will be described in detail with further reference to FIGS. 4 to 9.

[0127] The hinge bracket (200) may include a cabinet joint (211) that is fixedly mounted on the upper surface of the cabinet (2).

[0128] The cabinet joint (211) may be configured as a surface extending in a horizontal direction.

[0129] The cabinet joint (211) may be provided with a plurality of bracket fastening holes (211a) through which fastening members for fastening the cabinet joint (211) to the cabinet (2) pass.

[0130] In addition, the cabinet joint (211) may further include a rib penetration hole (211b) for a fixed rib (260) provided in the cabinet (2) to penetrate therethrough, and the fixed rib (260) may be referred to in FIG. 16.

[0131] The restraint lever (250) is placed on the cabinet joint (211) and can be rotatably connected based on one side of the cabinet joint (211).

[0132] A rotary pin coupling hole (222h) may be formed on one side of the cabinet coupling portion (211).

[0133] By means of the rotation pin (222) penetrating the restraint lever (250) and the rotation pin coupling hole (222h), the restraint lever (250) can be rotatably connected to the cabinet coupling part (211) around the rotation pin (222).

[0134] The restraint lever (250) may include a recessed portion (251) that forms a space in which a fixed rib (260) penetrating the rib penetration hole (211b) is positioned.

[0135] When the restraint lever (250) rotates, the fixed rib (260) can be positioned in the recessed portion (251) without interference with the restraint lever (250), and the restraint lever (250) can be restrained from rotating by the fixed rib (260).

[0136] The hinge bracket (200) may include a door coupling portion (212) that is fixedly mounted on the upper surface of the first door (10).

[0137] A connecting portion (213) can be formed between the cabinet connecting portion (211) and the door connecting portion (212).

[0138] The connecting portion (213) extends so as to be inclined from one side of the cabinet connecting portion (211) to one side of the door connecting portion (212), thereby connecting one side of the cabinet connecting portion (211) and one side of the door connecting portion (212).

[0139] For example, the connecting portion (213) may extend upwardly from the end of the cabinet joint portion (211) toward the front of the refrigerator (1).

[0140] The door joint (212) may be configured as a surface extending in a horizontal direction.

[0141] For example, the cabinet joint (211) and the door joint (212) can be positioned at different heights by the connecting portion (213).

[0142] The door joint (212) is positioned on the upper surface corresponding to the hinge mounting portion (105) of the first door (10), and can be rotatably connected based on one side of the first door (10).

[0143] A hinge pin joining hole (221h) may be formed on one side of the door joining portion (212).

[0144] By means of a hinge pin (221) that penetrates the door joint (212) and the hinge pin joint hole (221h), the hinge bracket (200) can be rotatably connected to the first door (10) around the rotation pin (222).

[0145] In the first door (10), a hole through which a hinge pin (221) can pass is formed at a position corresponding to the hinge pin joining hole (221h), and can be connected to the hinge pin joining hole (221h) of the hinge bracket (200) to provide a rotation axis on which the first door (10) can rotate.

[0146] The door coupling portion (212) may include a pair of cover coupling portions (214) that provide a fastening structure capable of fixing a hinge cover (350) described later to a hinge bracket (200).

[0147] For example, referring to FIG. 16, the hinge cover (350) is placed on the upper surface of the cover coupling portion (214) so ​​as to cover the cover coupling portion (214), and is fastened to the cover coupling portion (214) placed on both sides of the door coupling portion (212) in a hook-joint manner and can be fixed to the hinge bracket (200).

[0148] The door joint (212) may include a first surface (212a), which is one side facing the pressure surface (106) located in the inner direction of the first door (10), and a second surface (212b), which is the other side facing the outer direction of the first door (10) located opposite the one side.

[0149] The first surface (212a) of the door joint (212) can be formed to have a shape corresponding to the frame forming the hinge mounting portion (105) of the first door (10).

[0150] For example, the first surface (212a) of the door coupling portion (212) may be formed to protrude in a direction toward the pressing surface (106) of the first door (10), and the second surface (212b) of the door coupling portion (212) may be formed to be recessed in a direction toward the pressing surface (106) of the first door (10).

[0151] Accordingly, the door joint (212) can be formed to have a shape that is curved overall toward the pressure surface (106) of the first door (10).

[0152] In this case, at least a portion of the first surface (212a) may be formed to extend in the same direction as the direction in which the pressure surface (106) extends.

[0153] As described above, the pressure surface (106) is formed so as to extend obliquely rather than in the same direction as the front-back and left-right directions of the refrigerator (1), and at least a portion of the first surface (212a) may also be formed so as to extend obliquely rather than in the same direction as the front-back and left-right directions of the refrigerator (1).

[0154] In this way, a support member (230) can be formed on the first surface (212a) formed to extend in the same direction as the pressure surface (106) so that a step adjustment member (300) is fastened and fixed to the door joint (212).

[0155] The support member (230) may be placed in an area of ​​the first surface (212a) extending in the same direction as the pressure surface (106) of the first door (10).

[0156] For example, an inlet portion (215) may be formed on the first surface (212a) that is inlet to a predetermined area in the inner direction of the first surface (212a).

[0157] A support portion (230) can be formed by bending from the inner end of the inlet portion (215) formed in this manner toward the upper side of the door coupling portion (212).

[0158] The support member (230) bent upward can extend perpendicularly to the door joint member (212).

[0159] Accordingly, the upper end of the support portion (230) can be formed to protrude more upwardly than the upper end of the door joint portion (212).

[0160] The front end of the support member (230) may be located inward from the outermost surface of the first surface (212a).

[0161] Therefore, the support part (230) can be located on the inside of the introduction part (215).

[0162] One side of the support portion (230) facing the pressure surface (106) can be formed to extend in the same direction as the pressure surface (106).

[0163] Accordingly, the support member (230) can be formed to extend obliquely in the same direction as the direction in which the pressure surface (106) extends obliquely.

[0164] That is, one surface of the support portion (230) facing the pressure surface (106) can be parallel to the pressure surface (106) of the first door (10).

[0165] A fastening hole (230h) opened toward the pressure surface (106) of the first door (10) may be formed in the support member (230).

[0166] The fastening hole (230h) can function as a screw hole by having the inside tapped so that it can be fastened to the step adjustment member (300) using a screw connection method.

[0167] However, it is not limited to this, and the inside of the fastening hole (230h) may be formed without being tapped.

[0168] The fastening hole (230h) may be formed in the upper region of the support member (230), and the fastening hole (230h) may be formed to be located higher than the upper end of the cover joint (214).

[0169] Accordingly, even if a part of the step adjustment member (300) penetrates the fastening hole (230h), it may not interfere with the upper surface of the cover joint (214).

[0170] The step adjustment member (300) may include a fastening member (310) and a pressure member (320) connected to one side of the fastening member (310).

[0171] The fastening portion (310) is a portion fastened to the fastening hole (230h) of the support portion (230).

[0172] For example, the fastening portion (310) may include a fastening body portion (311) extending in one direction and having a screw thread (312) formed on the outer surface, and a fastening head portion (313) arranged on one side of the fastening body portion (311).

[0173] The fastening part (310) can be fastened to the fastening hole (230h) of the support part (230) in a screw manner by means of a screw thread (312) formed in the fastening body part (311).

[0174] For example, the fastening body (311) may be a tap tight screw that is fastened while forming a screw thread on the support member (230), which is the parent material.

[0175] In this case, the cross-section of the body of the fastening body (311) is formed into a triangle, so that it can be inserted into the parent material while making a tap.

[0176] In this way, when the fastening body (311) is formed with a tap tight screw, loosening due to vibration and impact can be reduced.

[0177] Additionally, it is desirable that the pitch between the screw threads (312) of the fastening body (311) be formed small to enable fine adjustment.

[0178] For example, the pitch between the screw threads (312) of the fastening body (311) may be 0.7 mm, but is not limited thereto.

[0179] The fastening head portion (313) can be formed to have a larger diameter than the fastening body portion (311) and can be combined with the pressing portion (320).

[0180] The pressurizing portion (320) is a portion that the user holds to rotate the step adjustment member (300) when rotating it.

[0181] The pressurizing part (320) may include a pressurizing body part (321) formed in a cylindrical shape with a diameter larger than the fastening head part (313) so that the user can easily hold and rotate it.

[0182] In this case, a plurality of protrusions (322) may be formed and arranged at a predetermined interval along the outer surface of the pressurized body (321).

[0183] In order to prevent slipping and increase friction when a user holds the pressurized body (321) and rotates it in one direction, the protrusion (322) may be formed to extend in a direction crossing the direction of rotation.

[0184] The pressurizing portion (320) may be formed to include an elastic material.

[0185] Since the pressurizing portion (320) is a portion that comes into contact with the pressurizing surface (106) of the first door (10), it is preferable to form it by including an elastic material to increase the buffering effect.

[0186] For example, the pressurizing portion (320) may be formed of a rubber material.

[0187] On the front side of the pressurized body part (321) that comes into contact with the pressurized surface (106) of the first door (10), a front side part (324) having an outer diameter smaller than that of the pressurized body part (321) can be formed.

[0188] For example, the front part (324) can be formed integrally with the pressurized body part (321).

[0189] It is preferable that the front surface of the front part (324) be formed to have a horizontal surface so that it makes maximum surface contact with the pressure surface (106) of the first door (10) to increase the contact surface.

[0190] An opening hole (321h) may be formed on one side of the pressurized body part (321) into which the fastening head part (313) is inserted.

[0191] It is preferable that the inner diameter of the opening hole (321h) be formed smaller than the outer diameter of the fastening head portion (313).

[0192] For example, since the pressurized body part (321) is formed of a material including an elastic material, when the fastening head part (313) is inserted through the opening hole (321h), by forcibly deforming the opening hole (321h) of the pressurized body part (321), the fastening head part (313) can be inserted into the pressurized part (320) through the opening hole (321h) of the pressurized body part (321).

[0193] A protruding pattern (323) may be formed on the inside of the fastening head portion (313) corresponding to the opening hole (321h).

[0194] For example, the protruding pattern (323) may be formed in a cross shape, but is not limited thereto.

[0195] A sunken fixing groove (314) may be formed in the fastening head portion (313) inserted into the pressurized body portion (321) so that the protruding pattern (323) can be inserted and fixed.

[0196] When the protruding pattern (323) is formed in a cross shape, the fixing groove (314) can be formed in a cross-shaped recessed pattern so that the protruding pattern (323) can be inserted and fixed.

[0197] Accordingly, even when the user holds the pressurized body part (321) and rotates the step adjustment member (300), no idle rotation occurs, and the pressurized part (320) and the fastening part (310) can rotate as one.

[0198] The step adjustment member (300) described in this way is fastened to the support member (230) of the hinge assembly (50) arranged on one side of the first door (10), and can be adjusted to selectively pressurize the first door (10) according to the user's selection.

[0199] The step adjustment member (300) can be fastened to the fastening hole (230h) by having the fastening member (310) face the fastening surface (106) of the first door (10) with the pressure portion (320).

[0200] It is preferable that the direction of the force applied by the step adjustment member (300) to the pressure surface (106) of the first door (10) be orthogonal to the direction in which the pressure surface (106) extends.

[0201] For example, referring to FIGS. 10 and 11, the first extension line (341) extended along the direction of the force that presses the pressure surface (106) of the first door (10) by the step adjustment member (300) can be perpendicular to the extended direction of the extended pressure surface (106) so as to have an inclined surface.

[0202] Accordingly, the contact area between the pressing portion (320) of the step adjustment member (300) and the pressing surface (106) of the first door (10) can be increased as much as possible, so that the pressing force can be provided to the pressing surface (106) without loss as much as possible, while reducing deformation of the pressing surface (106) that may occur when force is continuously applied to a local area.

[0203] Referring to FIGS. 10 and 12, when the step adjustment member (300) is initially coupled or in the initial setting state of the refrigerator (1), the step adjustment member (300) may be spaced apart from the pressure surface (106) of the first door (10) by a predetermined distance.

[0204] And referring to FIG. 11 and FIG. 13, in order to adjust the step of the first door (10), the user can adjust the step adjustment member (300) by rotating the step adjustment member (300) so that the pressing portion (320) presses the pressing surface (106) of the first door (10).

[0205] In this case, when the step adjustment member (300) protrudes further outward so that the force with which the step adjustment member (300) presses the pressure surface (106) of the first door (10) increases, the pressure surface (106) of the first door (10) can be retracted inward by a predetermined distance.

[0206] For example, referring to FIG. 14, the pressurizing portion (320) in contact with the pressurizing surface (106) may pressurize the pressurizing surface (106) more strongly so that an interference area (106a) is generated at a predetermined distance from the pressurizing surface (106).

[0207] In this way, when the step adjustment member (300) presses the pressure surface (106), a pressure force may be applied in the opposite direction to the support member (230) to which the step adjustment member (300) is fastened due to the reaction of the force.

[0208] Referring to FIGS. 4 and 5, the height of the support member (230) can be formed so that the lowermost surface of the pressure portion (320) of the step adjustment member (300) is positioned lower than the uppermost surface of the door coupling portion (212).

[0209] Accordingly, the height of the support member (230) extended in the upward direction can be reduced as much as possible, so that even when a pressure force is applied to the support member (230) in a direction perpendicular to the direction in which the support member (230) extends, the support member (230) can be stably supported without being bent and the step adjustment member (300).

[0210] However, in this case, since some areas of the pressurizing portion (320) are horizontally aligned with the inlet portion (215) of the door coupling portion (212), it may be inconvenient for the user to hold and turn the pressurizing portion (320).

[0211] In another embodiment, referring to FIG. 6, the height of the support member (230) can be formed so that the lowermost surface of the pressure portion (320) of the step adjustment member (300) is positioned higher than the uppermost surface of the door coupling portion (212).

[0212] In this case, since the pressure part (320) is not located horizontally on the same line as the inlet part (215) of the door joint part (212), but is located higher, the user can easily and quickly adjust the step without being obstructed by the inlet part (215) even when holding and turning the pressure part (320).

[0213] In another embodiment, referring to FIG. 15, a nut member (330) may be additionally connected to one side of the fastening member (310) to which the pressurizing member (320) is connected, and to the other side of the fastening member (310) opposite to it.

[0214] That is, the support member (230) can be placed between the pressure member (320) and the nut member (330).

[0215] As a nut member (330) is additionally fastened to the other side of the fastening member (310) in this way, loosening of the step adjustment member (300) due to vibration and impact can be reduced.

[0216] Also, referring to FIG. 16 as another embodiment, the hinge bracket (200) further includes a hinge cover (350) that covers at least a portion of the upper surface of the hinge bracket (200), and the step adjustment member (300) can be fastened to the hinge cover (350).

[0217] For example, the hinge cover (350) may be positioned to cover the upper portion of the door joint (212), which is a portion located in front of the hinge bracket (200).

[0218] Unlike the hinge bracket (200) formed from sheet metal, the hinge cover (350) can be formed from an injection molded material, which simplifies the process of forming a fastening structure to which the step adjustment member (300) is fastened and reduces production costs.

[0219] Referring to FIG. 17, a first hinge assembly (51) may be connected to the cabinet (2) and the first door (10) so that the first door (10) may be rotatable relative to the cabinet (2), and a second hinge assembly (52) may be connected to the cabinet (2) and the second door (20) so that the second door (20) may be rotatable relative to the cabinet (2).

[0220] The first hinge assembly (51) and the second hinge assembly (52) may each include a first door step adjustment member (301) for adjusting the front-back distance between the first door (10) and the cabinet (2), and a second door step adjustment member (302) for adjusting the front-back distance between the second door (20) and the cabinet (2).

[0221] The first door step adjustment member (301) and the second door step adjustment member (302) can be fastened to the first hinge bracket (201) and the second hinge bracket (202), respectively, so that the distance between the first door (10) and the second door (20) can be adjusted in a rotational manner.

[0222] By means of the first door step adjustment member (301) and the second door step adjustment member (302), the step difference in the front-back direction that may occur between the first door (10) and the second door (20) can be adjusted.

[0223] In this case, the first extension line (341) extended along the direction of movement of the first door step adjustment member (301) that moves in a rotational manner and the second extension line (342) extended along the direction of movement of the second door step adjustment member (302) that moves in a rotational manner may intersect each other.

[0224] The intersection point of the first extension line (341) and the second extension line (342) that intersect in this way can be located at the center line (343) of the cabinet (2) that extends in the front-back direction.

[0225] Hereinafter, a hinge assembly equipped with a step adjustment member according to another embodiment of the present invention will be described with reference to FIGS. 18 to 20.

[0226] The specific description of the step adjustment member described below can be applied as is to the description of various embodiments of the step adjustment member described above.

[0227] Referring to FIG. 18, a plurality of step adjustment members may be arranged in the hinge bracket (200).

[0228] For example, a first step adjustment member (361) and a second step adjustment member (362) may be arranged in the hinge bracket (200) so as to face the pressure surface (106).

[0229] The first step adjustment member (361) can be fastened to the first support member (231), and the second step adjustment member (362) can be fastened to the second support member (232).

[0230] For example, the first step adjustment member (361) and the second step adjustment member (362) are arranged on the first surface (212a) of the hinge bracket (200) and can be arranged on the same line with respect to the first surface (212a).

[0231] In addition, the first support part (231) and the second support part (232) are also arranged on the first surface (212a) of the hinge bracket (200), and can be arranged on the same line based on the first surface (212a).

[0232] The first step adjustment member (361) may be arranged to face one side of the pressure surface (106), and the second step adjustment member (362) may be arranged to face the other side of the pressure surface (106).

[0233] Accordingly, the first step adjustment member (361) can pressurize one side of the pressing surface (106), and the second step adjustment member (362) can pressurize the other side of the pressing surface (106).

[0234] In this way, since the pressure surface (106) is pressurized by a plurality of step adjustment members, more fine adjustment of the door step can be made.

[0235] In addition, the first step adjustment member (361) and the second step adjustment member (362) can pressurize one side and the other side of the pressing surface (106), respectively, so that the most balanced and uniform pressing force can be provided to the pressing surface (106).

[0236] Accordingly, the step of the door can be adjusted while minimizing the occurrence of bending of the pressure surface (106), which may occur when pressure is applied only to one or the other side of the pressure surface (106).

[0237] Referring to FIG. 19, a first step adjustment member (361) may be arranged on the hinge bracket (200) so as to face the pressure surface (106).

[0238] A connecting surface (107) connecting the pressing surface (106) and the side frame (102) of the first door (10) can be formed between the pressing surface (106) and the side frame (102).

[0239] The connecting surface (107) can form the front surface of the hinge mounting portion (105).

[0240] For example, the connecting surface (107) may extend parallel to the front surface of the first door (10).

[0241] However, it is not limited to this, and the connecting surface (107) may be extended obliquely to have an inclined surface.

[0242] For example, the connecting surface (107) may be extended to be inclined in the same direction as the pressure surface (106) is inclined.

[0243] In this case, the connecting surface (107) may be inclined at an angle different from the angle of inclination of the inclined surface of the pressurized surface (106).

[0244] The hinge bracket (200) may further include a second step adjustment member (361) positioned so as to face the connecting surface (107).

[0245] Accordingly, a plurality of step adjustment members that pressurize different surfaces of the first door (10) can be arranged on the hinge bracket (200).

[0246] Therefore, when adjusting the door step, the hinge bracket (200) can be provided with pressure in different directions, so that more precise adjustment of the door step can be made.

[0247] The second step adjustment member (361) can be placed adjacent to the hinge pin coupling hole (221h) of the hinge bracket (200).

[0248] Since the hinge pin joining hole (221h) of the hinge bracket (200) provides a rotation axis on which the first door (10) can rotate, the second step adjustment member (361) can be placed adjacent to the rotation axis of the first door (10).

[0249] For example, the hinge pin coupling hole (221h) of the hinge bracket (200) and the second step adjustment member (361) may be arranged so that at least some areas overlap each other based on the left-right direction of the refrigerator (1).

[0250] In the case of the embodiment described with reference to FIG. 19 as described above, it is described based on the arrangement of a plurality of step adjustment members in the hinge bracket (200), but it is not limited thereto.

[0251] For example, in the hinge bracket (200), the first step adjustment member (361) may not be arranged and only the second step adjustment member (362) may be arranged in a single unit.

[0252] Referring to FIG. 20, a first step adjustment member (361) may be arranged on the hinge bracket (200) so as to face the pressure surface (106).

[0253] Additionally, a second step adjustment member (361) may be further arranged on the hinge bracket (200) so as to face the connecting surface (107).

[0254] Accordingly, a plurality of step adjustment members that pressurize different surfaces of the first door (10) can be arranged on the hinge bracket (200).

[0255] Therefore, when adjusting the door step, the hinge bracket (200) can be provided with pressure in different directions, so that more precise adjustment of the door step can be made.

[0256] For example, the second step adjustment member (361) can be arranged so that at least a portion of the area overlaps the hinge pin coupling hole (221h) of the hinge bracket (200) in the vertical direction.

[0257] For example, the second support member (232) supporting the second step adjustment member (361) can be formed in a form that does not interfere with the hinge pin coupling hole (221h) by being positioned in front or behind the hinge pin coupling hole (221h).

[0258] The second step adjustment member (361) fastened to the second support member (232) can be positioned so as to be spaced apart from the hinge pin coupling hole (221h) in the vertical direction by a predetermined distance, so that the second step adjustment member (361) can also be formed in a form that does not interfere with the hinge pin coupling hole (221h).

[0259] In the case of the embodiment described with reference to FIG. 20 as described above, it is described based on the arrangement of multiple step adjustment members in the hinge bracket (200), but it is not limited thereto.

[0260] For example, in the hinge bracket (200), the first step adjustment member (361) may not be arranged and only the second step adjustment member (362) may be arranged in a single unit.

[0261] In the case of the embodiment of the hinge assembly described above, the method of opening and closing the door was described based on the method of opening and closing the door with the center of rotation by the rotation axis of the door fixed inside the door.

[0262] However, the hinge assembly according to the embodiment of the present invention is not limited thereto, and may be implemented so that the door is opened and closed in a manner in which the center of rotation of the door changes.

[0263] Hereinafter, with reference to FIGS. 21 and 22, a hinge assembly in which the center of rotation of the door changes will be described as an example, and the differences will be explained.

[0264] FIGS. 21 and 22 illustrate a hinge assembly according to another embodiment of the present invention, which includes a step adjustment member and in which the center of rotation of the door is changed.

[0265] The hinge assembly may include a hinge bracket (200) and a bushing member (400) formed on a hinge mounting portion (105) of the first door (10).

[0266] A first pin (271) and a second pin (272) extending downward may be arranged on one side of the door joint (212) of the hinge bracket (200).

[0267] For example, the first pin (271) and the second pin (272) may be spaced apart from each other at a predetermined distance and formed on one side adjacent to the end of the door coupling portion (212).

[0268] The bushing (400) can guide the movement of the first pin (271) and the second pin (272).

[0269] The bushing member (400) can be inserted into and fixed to the lower surface of the hinge mounting portion (105).

[0270] The bushing member (400) may have a guide slot (410) having a hollow space that provides a space into which the first pin (271) and the second pin (272) are inserted.

[0271] The guide slot (410) can be formed so that the upper direction into which the first pin (271) and the second pin (272) are inserted is open, and the lower direction, which is the opposite direction, is closed.

[0272] The guide slot (410) can be formed to have an overall U-shape.

[0273] For example, the guide slot (410) may have a U-shaped shape with both ends bent toward the front of the first door (10).

[0274] The guide slot (410) may have a shape in which various shapes of section areas, such as circular sections and / or straight sections, are connected.

[0275] The first pin (271) and the second pin (272) of the hinge bracket (200) can be inserted into the guide slot (410) of the bush member (400) and moved in a sliding manner along the guide slot (410).

[0276] Therefore, the bush member (400) can play a role in determining the rotational movement direction of the first door (10) while coming into contact with the first pin (271) and the second pin (272).

[0277] The rotational movement direction of the first door (10) may vary depending on the shape of the guide slot (410) formed in the bush member (400).

[0278] Accordingly, the first door (10) can be opened and closed in such a way that the center of rotation of the door changes.

[0279] Even in the case of a hinge assembly (50) in which the center of rotation of the door changes as described with reference to FIG. 21, a support member (230) may be formed on the hinge bracket (200), and a step adjustment member (300) may be fastened to the support member (230).

[0280] For example, the support member (230) and the step adjustment member (300) of the hinge bracket (200) can be arranged to face the pressure surface (106) of the first door (10).

[0281] The pressure surface (106) is arranged between the rear frame (101) and the side frame (102), and can be arranged to be biased toward one side of the first door (10).

[0282] For example, the pressure surface (106) may be formed as an inclined surface.

[0283] One side of the support portion (230) facing the pressure surface (106) can be formed to extend in the same direction as the pressure surface (106).

[0284] Accordingly, the support member (230) can be formed to extend obliquely in the same direction as the direction in which the pressure surface (106) extends obliquely.

[0285] That is, one surface of the support portion (230) facing the pressure surface (106) can be parallel to the pressure surface (106) of the first door (10).

[0286] Accordingly, the step adjustment member (300) fastened to the support member (230) can also be positioned to face the pressure surface (106), so that when the step adjustment member (300) comes into contact with the pressure surface (106) while the first door (10) is closed, surface contact with the pressure surface (106) can be made over the widest possible area.

[0287] In addition, in the case of detailed descriptions of the support member (230) and the step adjustment member (300) formed in the hinge bracket (200) and various embodiments, the contents applied to the embodiments described above based on the fixed rotation center of the door can be applied as is.

[0288] As described above, the refrigerator according to the present invention includes a step adjustment member for adjusting the distance in the front-rear direction between the door and the cabinet in the hinge assembly, so that the step adjustment can be performed in an area of ​​the hinge assembly where the dimensional change due to deformation is small.

[0289] In this way, since the step adjustment member is placed in a hinge assembly with high dimensional stability, away from the step generation area, the adjustment amount of the step adjustment member is hardly offset even when the door is significantly deformed, thereby increasing the usability of the step adjustment member and improving the step adjustment effect.

[0290] In addition, the refrigerator according to the present invention can adjust the door step while minimizing the occurrence of a warping phenomenon in which the back surface of the door is deformed and bent by the step adjustment member because the step adjustment member does not pressurize the back surface of the door that extends in the left-right direction, but pressurizes the pressing surface located on one side of the door adjacent to the hinge assembly.

[0291] In addition, the refrigerator according to the present invention is capable of improving the quality of door step adjustment by allowing linear fine adjustment rather than stepwise adjustment of the step distance since the step adjustment member is fastened to the hinge assembly in a screw-joint manner so that it can move forward and backward in a rotational manner.

[0292] In addition, since the refrigerator according to the present invention is arranged so that the step adjustment member is included in the hinge assembly located on one side of the door, the step adjustment member is not easily exposed to the user even when the door is opened, thereby improving the appearance quality of the door and enhancing the usability of the user.

[0293] Although the present invention has been described with reference to the drawings exemplified above, it is to be understood that the present invention is not limited to the embodiments and drawings disclosed herein, and that various modifications may be made by those skilled in the art within the scope of the technical idea of ​​the present invention. Furthermore, even if the operational effects according to the configuration of the present invention have not been explicitly described while describing the embodiments of the present invention, it is natural that the effects predictable by the corresponding configuration should also be acknowledged.
