[0054] Referring to FIGS. 5 to 7, FIG. 5 can be understood as a schematic drawing of a cross-section of a refrigerator (1) at a predetermined height viewed from above, and FIGS. 6 and 7 can be understood as schematic drawings centered on the filler magnet (100) and door magnets (200a, 200b) in FIG. 5.

[0055] Referring to FIG. 5, when the upper door (31, 32) closes the main body (10), the filler (43) (e.g., the filler (43) of FIG. 2) can seal the gap between the main body (10) and the upper door (31, 32). In order for the filler (43) to maintain the gap between the main body (10) and the upper door (31, 32) sealed, a filler magnet (100) may be arranged inside the filler (43), and door magnets (200a, 200b) may be arranged in each of the upper doors (31, 32). By the tensile force between the filler magnet (100) and the door magnets (200a, 200b), the filler (43) can seal the gap between the upper door (31, 32) and the main body (10).

[0056] According to one embodiment, the filler (43) may include a filler body (101), a filler magnet (100), and a filler heater (102). The filler body (101) may form the overall appearance of the filler (43). The filler body (101) may generally have a hexahedral shape having a predetermined height, a predetermined width, and a predetermined depth. For example, the filler body (101) may have a height substantially the same as the height of the upper doors (31, 32), but is not limited thereto. For example, the filler body (101) may be composed of a material including plastic and / or rubber, but is not limited thereto.

[0057] According to one embodiment, a filler magnet (100) and a filler heater (102) may be placed inside a filler body (101). The filler heater (102) may heat the filler (43) based on driving power supplied from a power source, thereby removing dew formed on the front surface of the filler (43).

[0058] According to one embodiment, the filler magnet (100) may be placed at the rear of the filler heater (102). By placing the filler heater (102) relatively forward with respect to the filler magnet (100), dew generated on the front surface of the filler (43) can be effectively removed.

[0059] In one embodiment, the filler magnet (100) may be formed as a rubber magnet. For example, the filler magnet (100) may be formed as a rubber magnet mixed with magnetic particles (e.g., magnetic powder) and a synthetic resin (e.g., chlorinated polyethylene (CPE)).

[0060] According to one embodiment, a pair of upper doors (31, 32) (e.g., the first door (31) and the second door (32) of FIG. 1, hereinafter referred to as upper doors) may include door magnets (200a, 200b). The door magnets (200a, 200b) may include a first door magnet (200a) disposed inside the first door (31) and a second door magnet (200b) disposed inside the second door (32).

[0061] In one embodiment, the door magnets (200a, 200b) may be formed of rubber magnets. For example, the door magnets (200a, 200b) may be formed of rubber magnets mixed with magnetic particles (e.g., magnetic powder) and synthetic resin (e.g., chlorinated polyethylene (CPE)).

The first-third side portion (220b) of the second door magnet (200b) may have a width of w12'. The first-fourth side portion (230b) of the second door magnet (200a) may have a width of w13'. For example, the width w12' of the first-third side portion (220b) may be substantially the same as the width w13' of the first-fourth side portion (230b).

[0079] In one embodiment, the first door magnet (200a) and the second door magnet (200b) may have substantially the same width and length. For example, w1 and w1' may be substantially the same. l1 and l1' may be substantially the same. w11 and w11' may be substantially the same. w12 and w12' may be substantially the same. w13 and w13' may be substantially the same.

[0080] In the present disclosure below, the description of the first door magnet (200a) may also be applied to the second door magnet (200b). In addition, the description of the second center (112) of the filler magnet (100) may also be applied to the third center (113), and the description of the second-first side (120) may also be applied to the second-second side (130).

[0081] According to one embodiment, in order to provide maximum tensile force between the filler magnet (100) and the door magnet (200a, 200b), a predetermined relationship can be formed between the separation distance (d) between the filler magnet (100) and the door magnet (200a, 200b), the width (w21, w21') of the second and third central portions (112, 113) of the filler magnet (100), the width (w23, w23') of the second side portions (120, 130) of the filler magnet (100), and the width (w12, w13, w12', w13') of the first side portions (220a, 230a, 220b, 230b) of the door magnet (200a, 200b).

[0082] For reference, FIGS. 12a to 12c are graphs showing tensile force according to the length relationship between a filler magnet (100) and door magnets (200a, 200b) according to one embodiment of the present disclosure. FIG. 12a shows <Example 1>, FIG. 12b shows <Example 2>, and FIG. 12c shows <Example 3>. Here, the tensile force can be defined as an external force required to freely move one of the magnets when an attractive force acts between two different magnets.

[0083] <Example 1> is a graph showing the tensile force (unit: Newton (N)) acting between the door magnet (200a, 200b) and the filler magnet (100) according to the length (w12 or w13) (unit: millimeter (mm)) of the first side (220a, 230a, 220b, 230b) of the door magnet (200a, 200b). In <Example 1>, it is assumed that the length of the second side (120, 130) of the filler magnet (100) corresponding to the first side (220a, 230a, 220b, 230) is 8 mm, and the distance (d) between the filler magnet (100) and the door magnet (200a, 200b) is 2.4 mm.

[0084] According to one embodiment, it can be confirmed that when the length of the first side (220a, 230a, 220b, 230b) is approximately 1.5 mm to 1.7 mm, the tensile force is maximum at approximately 0.82 N.

[0085] <Example 2> is a graph showing the tensile force (unit: Newton (N)) acting between the door magnets (200a, 200b) and the filler magnet (100) according to the length (w21) (unit: millimeter (mm)) of the second center portion (112) and the second-first side portion (120) of the filler magnet (100). In <Example 2>, it is assumed that the length of one of the first side portions (220a, 230a, 220b, 230) corresponding to the second center portion (112) and the second-first side portion (120) or the third center portion (113) and the second-second side portion (130) is 1.6 mm, and the distance (d) between the filler magnet (100) and the door magnets (200a, 200b) is 2.4 mm.

[0086] According to one embodiment, it can be confirmed that the tensile force is maximum at 0.78 N when the length of the second center (112) and the second-first side (120) is approximately 6.9 mm to 7.1 mm.

[0087] <Example 3> is a graph showing the tensile force (unit: Newton (N)) acting between the door magnet (200a, 200b) and the filler magnet (100) according to the length (w23) (unit: millimeter (mm)) of the second side (120, 130) of the filler magnet (100). In <Example 3>, it is assumed that the length of one of the first side (220a, 230a, 220b, 230) corresponding to the second side (120, 130) is 1.6 mm, and the distance (d) between the filler magnet (100) and the door magnet (200a, 200b) is 2.4 mm.

[0088] According to one embodiment, it can be confirmed that when the length of the second side (120, 130) is approximately 1.0 mm to 1.2 mm, the tensile force reaches a maximum of approximately 0.94 N.

[0089] According to one embodiment, the first side portions (220a, 230a, 220b, 230b) of the door magnets (200a, 200b) and the second side portions (120, 130) of the filler magnets (100) positioned to correspond to one of the first sides (220a, 230a, 220b, 230b) can be magnetized to face each other. For example, the 1-1 side portion (220a) of the first door magnet (200a) can be magnetized in a leftward direction (e.g., in the -x-axis direction), and the 2-1 side portion (120) of the filler magnet (100) can be magnetized in a rightward direction (e.g., in the +x-axis direction). For example, the 1-4 side (230b) of the 2nd door magnet (200b) may be magnetized in the right direction (e.g., +x-axis direction), and the 2-2 side (130) of the filler magnet (100) may be magnetized in the left direction (e.g., -x-axis direction).

[0090] According to one embodiment, in order to facilitate magnetization of the first side (220a, 230a, 220b, 230b) of the door magnet (200a, 200b) and / or the second side (120, 130) of the filler magnet (100) in the left or right direction, one or more slits (e.g., slits (811, 813, 831, 833) of FIG. 8) may be formed in the first side (220a, 230a, 220b, 230b) and the second side (120, 130). The above slits (811, 813, 831, 833) can be formed at a predetermined position of the first side (220a, 230a, 220b, 230b) and / or the second side (120, 130). In this regard, it will be described below in FIG. 8.

[0091] FIG. 8 is a plan view of a door magnet (200) (e.g., the first door magnet (200a) or the second door magnet (200b) of FIG. 5) according to one embodiment of the present disclosure.

[0092] The door magnet (200) illustrated in FIG. 8 or below may be applied to either the first door magnet (200a) or the second door magnet (200b). The embodiment of FIG. 8 may correspond in part or in whole to the embodiments of FIGS. 5 to 7, and FIG. 8 may be selectively combined with FIGS. 5 to 7.

[0093] Referring to FIG. 8, the structure of the illustrated door magnet (200) can be equally applied to a filler magnet (e.g., the filler magnet (100) of FIG. 5) including first to third central portions (111, 112, 113) and second side portions (120, 130). For example, the slits (811, 813, 831, 833) formed in the first side portions (220, 230) of the door magnet (200) can also be applied to the second side portions (120, 130) of the filler magnet (100).

[0094] According to one embodiment, the door magnet (200) may include a center portion (210) (e.g., the center portion (210a, 210b) of FIG. 6) and side portions (220, 230) located on either side of the center portion. When the door magnet (200) is viewed from the front (e.g., in the +y-axis direction) to the rear (e.g., in the -y-axis direction), the side portions (220, 230) may include a left portion (220) located on the left side (e.g., the 1-1 side portion (220a) or the 1-3 side portion (220b) of FIG. 6) and a right portion (230) (e.g., the 1-2 side portion (230a) or the 1-4 side portion (230b) of FIG. 6).

[0095] According to one embodiment, the door magnet (200) may be formed of a rubber magnet. For example, the door magnet (200) may be formed by mixing a magnetic material (320) (e.g., magnetic powder) and a synthetic resin (310) (e.g., chlorinated polyethylene (CPE)). The magnetic material (320) may be arranged in a plate shape inside the door magnet (200). The door magnet (200) may be magnetized in a predetermined direction depending on the direction in which the magnetic material (320) is arranged.

[0096] According to one embodiment, the door magnet (200) may be magnetized to exhibit anisotropy. During the extrusion process of the mixture of the synthetic resin (310) and the magnetic material (320) constituting the door magnet (200), the door magnet (200) may be magnetized to exhibit different directions. The bold arrows illustrated in FIG. 8 may be understood to schematically indicate the magnetization directions of the door magnet (200).

[0097] According to one embodiment, the central portion (210) can be magnetized to face forward. The plate-shaped magnetic material (320) disposed within the central portion (210) can be disposed substantially in a transverse direction (e.g., in the x-axis direction).

[0098] According to one embodiment, the left portion (220) may be magnetized to face the left direction (e.g., the -x-axis direction). The right portion (230) may be magnetized to face the right direction (e.g., the +x-axis direction). The plate-shaped magnetic material (320) disposed within the left portion (220) or the right portion (230) may be disposed in a vertical direction (e.g., the y-axis direction).

[0099] According to one embodiment, a plate-shaped magnetic material (320) disposed inside the side (220, 230) may be disposed vertically so that the side (220, 230) is oriented to face left or right.

[0100] According to one embodiment, slits (811, 813, 831, 833) may be formed at predetermined positions of the side portions (220, 230) so that the center portion (210) and the side portions (220, 230) are magnetized in different directions, i.e., to increase the magnetization anisotropy of the door magnet (200).

[0101] According to one embodiment, the slits (811, 831, 831, 833) may be formed in multiple numbers. The slits (811, 813, 831, 833) may include a first slit (811) and a second slit (813) formed in the left side (220), and a third slit (831) and a fourth slit (833) formed in the right side (230).

[0102] According to one embodiment, the slits (811, 813, 831, 833) may be formed from the front end of the door magnet (100) to a predetermined length in the rearward direction, or may be formed from the rear end of the door magnet (100) to a predetermined length in the frontward direction.

[0103] For example, the first slit (811) and the third slit (831) may be formed in the forward direction from the rear end of the door magnet (100). The second slit (813) and the fourth slit (833) may be formed in the backward direction from the front end of the door magnet (100). Here, the slits (811, 831) formed in the forward direction from the rear end of the door magnet (100) may be referred to as “rear slits,” and the slits (813, 833) formed in the forward direction from the front end of the door magnet (100) may be referred to as “front slits.”

[0104] According to one embodiment, as the first to fourth slits (811, 813, 831, 833) are formed in a vertical direction, the plate-shaped magnetic material (320) disposed inside the side portions (220, 230) can be disposed in a vertical direction. As a result, the left portion (220) and / or the right portion (230) can be easily magnetized in the left or right direction.

[0105] According to one embodiment, the length of the slits (811, 813, 831, 833) may be less than half of the length of the door magnet (200) (e.g., length l1 or l1' of FIG. 7), but is not limited thereto. For example, the first to fourth slits (811, 831, 831, 833) may extend within a range that does not encroach on the second auxiliary line (s2) that passes through the center of the door magnet (200) and extends parallel to the x-axis direction. Since the lengths of the slits (811, 813, 831, 833) are formed at a predetermined ratio with respect to the length of the door magnet (200), the durability of the door magnet (200) can be improved. However, it is not limited thereto, and the length and width of the slits (811, 813, 831, 833) may be determined depending on the material characteristics (e.g., rigidity or elasticity) of the synthetic resin (310) constituting the door magnet (200).

[0106] According to one embodiment, the slits (811, 831, 831, 833) may be formed symmetrically with respect to a first auxiliary line (s1) that passes through the center of the door magnet (200) and extends parallel to the y-axis direction. For example, the first slit (811) and the third slit (831) may be formed symmetrically with respect to the first auxiliary line (s1), and the second slit (831) and the fourth slit (833) may be formed symmetrically with respect to the first auxiliary line (s1).

[0107] FIG. 9 is a plan view of a door magnet (200) (e.g., the door magnet (200) of FIG. 8) according to one embodiment of the present disclosure.

[0108] FIG. 10 is a plan view of a door magnet (200) according to one embodiment of the present disclosure.

[0109] FIG. 11 is a plan view of a door magnet (200) according to one embodiment of the present disclosure.

[0110] FIGS. 9 to 11 may be understood as expanded embodiments of the door magnet (200) of FIG. 8. For example, FIG. 9 illustrates a case where one slit (911, 913) is formed on each of the side portions (220, 230) of the door magnet (200), FIG. 10 illustrates a case where two slits (1011, 1013, 1031, 1033) are formed on each of the side portions (220, 230) of the door magnet (200), and FIG. 11 illustrates a case where three slits (1111, 1113, 1115, 1131, 1133, 1135) are formed on each of the side portions (220, 230) of the door magnet (200). In addition to what is shown, slits of various shapes and numbers may be formed on the sides of the door magnet (200) and the filler magnet (e.g., the filler magnet (100) of FIG. 5), so that the magnetization direction of the magnet side can be anisotropic.

[0111] Although not shown, the magnetization direction in the door magnet (200) illustrated in FIGS. 9 to 11 may be substantially the same as the magnetization direction in FIG. 8. For example, the center (210) of the door magnet (200) illustrated in FIGS. 9 to 11 may be magnetized forward (e.g., in the +y-axis direction), and the side portions (220, 230) of the door magnet (200) may be magnetized laterally toward the outside (e.g., in the +x-axis or -x-axis direction).

[0112] The door magnet (200) illustrated in FIGS. 9 to 11 can be optionally combined with the door magnet of FIGS. 5 to 7 (e.g., the first door magnet (200a) or the second door magnet (200b) of FIGS. 5 to 7).

[0113] Referring to FIG. 9, slits (911, 931) may be formed in each of the sides (220, 230). The slits (911, 931) may include a first slit (911) formed in the left side (220) and a second slit (931) formed in the right side (230).

[0114] According to one embodiment, the first slit (911) and the second slit (931) may be formed in a forward direction (e.g., in the +y-axis direction) from the rear end of the door magnet (200). In other words, the door magnet (200) of FIG. 9 may include rear slits (911, 931) formed on the sides (220, 230).

[0115] According to one embodiment, the first slit (911) and the second slit (931) may be formed at positions symmetrical with respect to the first auxiliary line (s1) (e.g., the first auxiliary line (s1) of FIG. 8).

[0116] According to one embodiment, the first slit and the second slit (911, 931) may have a predetermined width in the x-axis direction and a predetermined length in the y-axis direction. For example, the first slit (911) and the second slit (931) may have a length shorter than half the length of the door magnet (200) (e.g., length l1 or length l1' of FIG. 7). The first slit (911) and the second slit (931) may be formed from the front or rear end of the door magnet (200) and may have a length that does not exceed the second auxiliary line (s2) (e.g., second auxiliary line (s2) of FIG. 8). However, the present invention is not limited thereto, and the slits (911, 931) may have various lengths in the y-axis direction depending on the material and shape of the door magnet (200).

[0117] According to one embodiment, the magnetization of the door magnet (200) can be easily anisotropically demagnetized by the slits (911, 931) formed in the side portions (220, 230). As a result, the tensile force between the door magnet (200) and the filler magnet (100) can be increased.

[0118] Referring to FIG. 10, slits (1011, 1013, 1031, 1033) may be formed in each of the sides (220, 230). The slits (1011, 1013, 1031, 1033) may include a 1-1 slit (1011) and a 1-2 slit (1013) formed in the left side (220) and a 2-1 slit (1031) and a 2-2 slit (1033) formed in the right side (230).

[0119] According to one embodiment, when a plurality of slits (1011, 1013, 1031, 1033) are formed in each of the sides (220, 230), each of the slits (1011, 1013, 1031, 1033) may be arranged at a predetermined interval.

[0120] According to one embodiment, the first-first slit (1011) and the second-first slit (1031) may be formed in a forward direction from the rear end of the door magnet (200) (e.g., in the +y-axis direction). The first-second slit (1031) and the second-second slit (1033) may be formed in a forward direction from the front end of the door magnet (200) (e.g., in the -y-axis direction). In other words, the door magnet (200) of FIG. 10 may include two rear slits (1011, 1031) and two front slits (1013, 1033) formed on the sides (220, 230).

[0121] According to one embodiment, some of the plurality of slits (1011, 1013, 1031, 1033) may be formed at positions symmetrical with respect to the first auxiliary line (s1). For example, the 1-1 slit (1011) and the 2-1 slit (1031) may be formed symmetrically with respect to the first auxiliary line (s1). For example, the 1-2 slit (1013) and the 2-2 slit (1033) may be formed symmetrically with respect to the first auxiliary line (s1).

[0122] According to one embodiment, the plurality of slits (1011, 1013, 1031, 1033) may have a predetermined width in the x-axis direction and a predetermined length in the y-axis direction. For example, the plurality of slits (1011, 1013, 1031, 1033) may have a length shorter than half the length of the door magnet (200) (e.g., length l1 or length l1' of FIG. 7). The plurality of slits (1011, 1013, 1031, 1033) may be formed from the front or rear end of the door magnet (200) and may have a length not exceeding the second auxiliary line (s2) (e.g., second auxiliary line (s2) of FIG. 8).

[0123] According to one embodiment, the lengths of the first-first slit (1011) and the second-first slit (1031) may be relatively longer than the lengths of the first-second slit (1013) and the second-second slit (1033).

[0124] Not limited to what is shown, some or all of the plurality of slits (1011, 1013, 1031, 1033) may have various lengths in the y-axis direction depending on the material and shape of the door magnet (200).

[0125] According to one embodiment, the magnetization of the door magnet (200) can be easily anisotropically demagnetized by a plurality of slits (1011, 1013, 1031, 1033) formed on the side (220, 230). As a result, the tensile force between the door magnet (200) and the filler magnet (100) can be increased.

[0126] Referring to FIG. 11, slits (1111, 1113, 1115, 1131, 1133, 1135) may be formed in each of the sides (220, 230). The slits (1111, 1113, 1115, 1131, 1133, 1135) may include a first-first slit (1111), a first-second slit (1113), and a first-third slit (1115) formed in the left side (220). The slits (1111, 1113, 1115, 1131, 1133, 1135) may include a 2-1 slit (1131), a 2-2 slit (1133), and a 2-3 slit (1115) formed on the right side (230).

[0127] According to one embodiment, when a plurality of slits (1111, 1113, 1115, 1131, 1133, 1135) are formed in each of the sides (220, 230), each of the slits (1111, 1113, 1115, 1131, 1133, 1135) may be formed at a predetermined interval.

[0128] According to one embodiment, the first-first slit (1111), the first-third slit (1115), the second-first slit (1131), and the second-third slit (1135) may be formed in a forward direction from the rear end of the door magnet (200) (e.g., in the +y-axis direction). The first-second slit (1131) and the second-second slit (1133) may be formed in a forward direction from the front end of the door magnet (200) (e.g., in the -y-axis direction). In other words, the door magnet (200) of FIG. 11 may include four rear slits (1111, 1115, 1131, 1135) and two front slits (1113, 1133) formed on the sides (220, 230).

[0129] According to one embodiment, some of the plurality of slits (1111, 1113, 1115, 1131, 1133, 1135) may be formed at positions symmetrical with respect to the first auxiliary line (s1). For example, the 1-1 slit (1111) and the 2-1 slit (1131) may be formed symmetrically with respect to the first auxiliary line (s1). For example, the 1-2 slit (1113) and the 2-2 slit (1133) may be formed symmetrically with respect to the first auxiliary line (s1). For example, the 1-3 slit (1115) and the 2-3 slit (1135) may be formed symmetrically with respect to the first auxiliary line (s1).

[0130] According to one embodiment, the plurality of slits (1111, 1113, 1115, 1131, 1133, 1135) may have a predetermined width in the x-axis direction and a predetermined length in the y-axis direction. For example, the plurality of slits (1111, 1113, 1115, 1131, 1133, 1135) may have a length shorter than half the length of the door magnet (200) (e.g., length l1 or length l1' of FIG. 7). The plurality of slits (1111, 1113, 1115, 1131, 1133, 1135) may be formed from the front or rear end of the door magnet (200) and may have a length that does not exceed the second auxiliary line (s2) (e.g., the second auxiliary line (s2) of FIG. 8).

[0131] According to one embodiment, the lengths of the first-first slit (1111), the first-third slit (1115), the second-first slit (1131) and the second-third slit (1135) may be relatively longer than the lengths of the first-second slit (1113) and the second-second slit (1133).

[0132] Not limited to what is shown, some or all of the plurality of slits (1111, 1113, 1115, 1131, 1133, 1135) may have various lengths in the y-axis direction depending on the material and shape of the door magnet (200).

[0133] According to one embodiment, the magnetization of the door magnet (200) can be easily anisotropically demagnetized by a plurality of slits (1011, 1013, 1031, 1033) formed on the side (220, 230). As a result, the tensile force between the door magnet (200) and the filler magnet (100) can be increased.

[0134] According to one embodiment, the structure of the door magnet (200) illustrated in FIGS. 8 to 11 may also be applied to a filler magnet (e.g., the filler magnet (100) of FIG. 6). For example, the slits formed on the sides (220, 230) of the door magnet (200) may also be formed on the sides of the filler magnet (100) (e.g., the 2-1 side (120) and the 2-2 side (130) of FIG. 6). In this case, the slits formed on the side (220, 230) of the door magnet (200) may include a first front slit located in front of the door magnet (200) and a first rear slit located in the rear of the door magnet (200), and the slits formed on the side (120, 130) of the filler magnet (100) may include a second front slit located in front of the filler magnet (100) and a second rear slit located in the rear of the filler magnet (100).

[0135] According to one embodiment, due to the slits formed in the door magnet (200) and the filler magnet (100), the magnetization of the door magnet (200) and the filler magnet (100) can be easily anisotropic. As a result, the tensile force between the door magnet (200) and the filler magnet (100) can be increased.

[0136] According to one embodiment, the door magnet (200) and the filler magnet (100) can be applied to various home appliances in addition to refrigerators (e.g., the refrigerator (1) of FIG. 1). For example, the door magnet (200) and the filler magnet (100) can be applied to home appliances consisting of a main body and a door, such as washing machines, dryers, clothes managers, dishwashers, and (micro) ovens, whereby the door magnet (200) is placed inside the door of the home appliance, and the filler magnet (100) is placed in an area corresponding to the door magnet (200) inside the main body of the home appliance, thereby strengthening the adhesive force between the door and the main body.

[0137] A refrigerator (1) according to one embodiment of the present disclosure may provide a door magnet (200) and a filler magnet (100) that strengthen the fixing force between the upper door (31, 32) and the filler (43).

[0138] A refrigerator (1) according to one embodiment of the present disclosure can save energy used to remove dew generated due to a temperature difference inside and outside a filler (43) when the upper door (31, 32) is closed.

[0139] A refrigerator (1) according to one embodiment of the present disclosure can keep objects stored in the storage compartment (21, 22, 23) fresh by effectively sealing the storage compartment (21, 22, 23) when the upper door (31, 32) is closed.
