The magnetic component 150 may include a cover 190, which is configured to be rotatably assembled to the front of the shell 170 in the left-right direction to cover the open front of the shell 170.

[0098] The housing 160 may be assembled to the rear surface 39 of the door 30. In order to assemble the housing 160, the door 30 may include an insertion hole 51 formed to allow a portion of the housing 160 to be inserted into the rear surface 39 of the door 30. The rear portion of the housing 160 may be inserted into the insertion hole 51 formed on the rear surface 39 of the door 30.

[0099] The door 30 may include a pair of assembly grooves 53 formed at the upper and lower portions of the insertion hole 51, respectively, to allow assembly of a portion of the housing 160 inserted into the insertion hole 51. The pair of assembly grooves 53 may be formed along the edge of the insertion hole 51 at the upper and lower portions of the insertion hole 51, respectively. The assembly groove 53 formed at the upper portion of the insertion hole 51 among the pair of assembly grooves 53 may be formed such that opposite ends thereof extend to portions on the left and right sides of the insertion hole 51. The assembly groove 53 formed at the lower portion of the insertion hole 51 among the pair of assembly grooves 53 may be formed such that opposite ends thereof extend to portions on the left and right sides of the insertion hole 51.

[0100] The door 30 may include a pair of assembling portions 55 formed on left and right sides of the insertion hole 51 , respectively, to allow assembling of a portion of the housing 160 inserted into the insertion hole 51 .

[0101] The housing 160 may include a pair of assembly ribs 161 configured to be assembled by being fitted into a pair of assembly grooves 53 formed on the rear surface 39 of the door 30. The pair of assembly ribs 161 may be formed at a rear edge portion of the housing 160 to protrude rearward. That is, the pair of assembly ribs 161 may be formed to protrude toward the pair of assembly grooves 53 in which the pair of assembly ribs 161 are fitted and assembled.

[0102] The housing 160 may include a pair of assembling hooks 163 configured to be assembled by fitting into a pair of assembling portions 55 formed on the rear surface 39 of the door 30. The pair of assembling hooks 163 may be formed on left and right sides of the housing 160, respectively.

[0103] The housing 160 may include a plurality of fixing grooves 165 to which the housing 170 is fixed. The plurality of fixing grooves 165 may be formed inside the housing 160 so as to fix the housing 170 to the inside of the housing 160. The plurality of fixing grooves 165 may be formed on the upper surface, the lower surface, the left surface, and the right surface of the inside of the housing 160, respectively.

[0104] The magnetic member 150 may include a housing 170 having an open front and fixed to the inside of the housing 160. The housing 160 may include a receiving portion 167 in which the housing 170 is received by having an open front. The housing 170 may include an opening 171 configured to receive a portion of the magnet 180.

[0105] The housing 170 may include a plurality of housing fixing hooks 172, and the plurality of housing fixing hooks 172 are provided to be fixed to a plurality of fixing grooves 165 formed in the housing 160. The plurality of housing fixing hooks 172 may be formed on the upper surface, the lower surface, the left surface, and the right surface of the exterior of the housing 170 to respectively correspond to the plurality of fixing grooves 165. By fixing the plurality of housing fixing hooks 172 to the plurality of fixing grooves 165, the housing 170 accommodated in the accommodation portion 167 of the housing 160 may be fixed to the interior of the housing 160.

[0106] The housing 170 may include a pair of rotation protrusions 173 to which the cover 190 is rotatably assembled. The pair of rotation protrusions 173 may be formed to protrude from the upper and lower parts of the interior of the housing 170, respectively. The pair of rotation protrusions 173 may be formed inside the housing 170 at a portion away from the hinge shaft 35 of the door 30 in the left-right direction relative to the center of the housing 170. The cover 190 may rotate in the left-right direction around the pair of rotation protrusions 173. However, the pair of rotation protrusions 173 are not limited to being formed inside the housing 170 at a portion away from the hinge shaft 35 of the door 30 in the left-right direction relative to the center of the housing 170. That is, the pair of rotation protrusions 173 may be formed inside the housing 170 at a portion close to the hinge shaft 35 of the door 30 in the left-right direction relative to the center of the housing 170.

[0107] As described above, since the cover 190 rotates in the left-right direction about the pair of rotating protrusions 173, when the door 30 is opened or closed, the magnetic member 150 rotates according to the angle at which the door 30 is opened or closed, so that the attachment of the contact member 120 and the magnetic member 150 can be maintained. That is, when the door 30 is opened or closed, the cover 190 of the magnetic member 150 rotates at an angle corresponding to the angle at which the door 30 is opened or closed, so that the attachment of the contact member 120 and the magnetic member 150 can be maintained. That is, when the door 30 is opened or closed in a state where the contact member 120 is attached to the magnetic member 150, the cover 190 can be rotated so that the door 30 is opened or closed while the contact member 120 keeps the attachment surface attached to the magnetic member 150. When the door 30 is opened or closed, in the case where the cover 190 is not rotated so that the door 30 is opened or closed while the contact member 120 maintains the attachment surface attached to the magnetic member 150, because the attachment of the contact member 120 and the magnetic member 150 can be maintained, the contact member 120 and the magnetic member 150 may not be able to maintain parallel attachment, that is, only a portion of the attachment may be maintained, rather than maintaining surface contact. Therefore, when the door 30 is opened or closed, in the case where the cover 190 is rotated so that the door 30 is opened or closed while the contact member 120 maintains the attachment surface attached to the magnetic member 150, the contact member 120 and the magnetic member 150 will remain in a parallel state and can completely maintain surface contact.

[0108] The magnetic member 150 may include a magnet 180. When the slider 110 moves forward, the magnet 180 may attach the contact member 120 to the magnetic member 150 by magnetic force. The closing force of the door 30 may be adjusted by adjusting the size and / or thickness of the magnet 180.

[0109] The magnetic component 150 may include a cover 190 rotatably assembled to the front of the housing 170 in the left-right direction. The cover 190 may cover the open front of the housing 170. The cover 190 may include a pair of fixing hooks 191 to which the magnet 180 is fixed. The pair of fixing hooks 191 may be formed on the left and right sides of the cover 190, respectively. Since the magnet 180 is fixed to a pair of fixing hooks 191 formed on the cover 190, the magnet 180 may rotate with the cover 190. In addition, since the magnet 180 is fixed to the inside of the cover 190, the magnet 180 may be prevented from being exposed to the outside by the cover 190. The magnet 180 may be prevented from directly contacting the contact part 120 of the sliding member 110 by the cover 190.

[0110] The cover 190 may include a pair of rotation holes 192 configured to allow a pair of rotation protrusions 173 formed on the housing 170 to be rotatably assembled. The pair of rotation holes 192 may be formed at the upper and lower portions of the cover 190 to correspond to the pair of rotation protrusions 173, respectively.

[0111] The following will refer to Figures 9 to 20 The operation of the door opening and closing device 100 is described in detail. Figures 9 to 17 It is shown to describe the operation of opening and closing the first door 31 by the door opening and closing device 100 , so the first door 31 will be referred to as the door 30 for convenience.

[0112] Fig. 9 is a view showing a state in which a door according to the embodiment is closed. Fig.10 is a view illustrating an elastic rod provided at an upper portion of a door and a cam member provided on an upper hinge when the door is closed according to an embodiment. Fig.11 It is shown in Fig. 9 A view of a state in which the contact part is attached to the magnetic part when the slide member in FIG. 1 moves forward. Fig.12 is a perspective view showing a state in which a contact member is attached to a magnetic member according to the embodiment. Fig.13 It is shown that due to Fig.11 A view of the cover of the magnetic assembly rotating as the middle slide moves forward to open the door. Fig.14 is a perspective view illustrating that a cover is rotated in a state where a contact member is attached to a magnetic member according to an embodiment. Fig.15 is a view illustrating states of an elastic lever and a cam member when a door is fully opened according to an embodiment. Fig.16 is a view showing that a door is completely opened in a state where the door is partially opened by a slider according to an embodiment. Fig.17 is a diagram illustrating states of an elastic lever and a cam member when a door is partially opened according to an embodiment. Fig.18is a view illustrating that a door is automatically closed by a slider in a state in which the door is partially opened by the slider according to an embodiment. Fig.19 is a view illustrating that a cover is rotated when a door is closed by a slider according to an embodiment. Fig. 20 2 is a view showing that after a door is closed by the slider, the slider returns to its original position while a contact part of the slider is disengaged from a magnetic part according to an embodiment.

[0113] like Fig. 9 As shown, when the door 30 is closed, the contact member 120 of the slider 110 may be in a state of being spaced apart from the magnetic member 150. In order to partially open the door 30 when the door 30 is closed, the first switch 41 (see Figure 3 ) to operate the sliding member 110.

[0114] like Fig.10 As shown, when the door 30 is closed, the elastic rod 60 provided at the upper portion of the door 30 and the cam member 70 provided on the upper hinge 33 may be in a state of contacting each other.

[0115] The elastic rod 60 can transmit elastic force in the direction of closing the door 30, so that when the door 30 is closed, the door 30 can be in close contact with the main body 10. When the door 30 is in close contact with the main body 10 through the elastic rod 60, the storage chamber 20 (see Figure 2 ) to prevent cold air leakage.

[0116] The elastic rod 60 is formed of a material having elasticity, is configured to be bent in a U-shape, and may include a roller 61 that contacts the cam member 70. The roller 61 may move along the shape of the cam surface 71 by contacting the cam surface 71 of the cam member 70. When the door 30 is fully opened, the roller 61 may be maintained in a state of not contacting the cam surface 71 of the cam member 70. When the roller 61 contacts the cam surface 71 in the process of closing the door 30, the elastic rod 60 is compressed to accumulate elastic force.

[0117] When the door 30 is closed, the cam member 70 contacts the roller 61 of the elastic rod 60, so that the elastic rod 60 can accumulate elastic force. In addition, the cam member 70 transmits the elastic force accumulated by the elastic member 60 to the door 30 in the direction of closing the door 30, so that the door 30 can be in close contact with the main body 10 through the elastic member 60.

[0118] The cam member 70 may include a cam surface 71, and the roller 61 of the elastic rod 60 contacts the cam surface 71. The cam surface 71 may include an inflection point 73, which is a reference point when the door 30 is opened and closed, and a first contact surface 75 and a second contact surface 77, respectively disposed at the lower side and the upper side of the inflection point 73 to have opposite slopes relative to the inflection point 73.

[0119] When the door 30 is in a fully opened state, the roller 61 of the elastic rod 60 is kept out of contact with the cam surface 71 of the cam member 70 , and in the process of closing the door 30 , the roller 61 may contact with the first contact surface 75 of the cam surface 71 .

[0120] In the process of closing the door 30, the roller 61 in contact with the first contact surface 75 may move along the cam surface 71 while sequentially contacting the first contact surface 75, the inflection point 73, and the second contact surface 77. When the roller 61 moves to the inflection point 73 after contacting the first contact surface 75, the elastic rod 60 may accumulate elastic force. When the user closes the door 30 enough to make the roller 61 exceed the inflection point 73, the elastic rod 60 may transfer the accumulated elastic force to the door 30 when the roller 61 moves from the inflection point 73 to the second contact surface 77. That is, when the user closes the door 30 by transferring to the door 30 a force that is only enough to make the roller 61 of the elastic rod 60 exceed the inflection point 73, even if the user's force is no longer transferred to the door 30, the door 30 may be in close contact with the body 10 by receiving the elastic force in the direction of closing the door 30. When the door 30 is closed, the roller 61 of the elastic rod 60 may be in a state of contacting the second contact surface 77 of the cam member 70.

[0121] When the door 30 is closed, the first switch 41 (see Figure 3 ) is touched to operate the sliding member 110, such as Fig.11 and Fig.12 As shown, the slider 110 moves forward so that the contact member 120 can be attached to the magnetic member 150. That is, the magnet 121 of the contact member 120 and the magnet 180 of the magnetic member 150 can be attached by magnetic force. In this case, the magnet 121 of the contact member 120 and the magnet 180 of the magnetic member 150 can be prevented from directly contacting each other by the covers 122 and 190, respectively.

[0122] like Fig.13 and Fig.14As shown, when the sliding member 110 moves further forward in a state where the contact member 120 is attached to the magnetic member 150, the contact member 120 pushes the magnetic member 150 so that the door 30 can be partially opened. At this time, the cover 190 of the magnetic member 150 can rotate around the pair of rotating protrusions 173 so as to maintain a constant magnetic force between the cover 190 and the contact member 120 according to the opening of the door 30. The cover 190 of the magnetic member 150 can rotate around the pair of rotating protrusions 173 so that the contact member 120 and the magnetic member 150 can remain parallel to each other to make surface contact with each other according to the opening of the door 30. That is, the cover 190 of the magnetic member 150 can rotate around the pair of rotating protrusions 173 at an angle corresponding to the opening angle of the door 30, so that the contact member 120 and the magnetic member 150 can remain parallel to each other to make surface contact with each other according to the opening of the door 30. Because the door 30 rotates around the hinge shaft 35 (see Figure 5 ) rotates clockwise, so the cover 190 can rotate counterclockwise around a pair of rotating protrusions 173.

[0123] like Fig.15 As shown, when the door 30 is partially opened, when the roller 61 of the elastic rod 60 moves from the sliding member 110 (see Fig.12 and Fig.13 ) receives a force sufficient to pass through the second contact surface 77 and exceed the inflection point 73, as Fig.16 As shown, the door 30 can be fully opened while the roller 61 of the elastic rod 60 passes the second contact surface 77 and crosses the inflection point 73 .

[0124] When the door 30 may be fully opened, the slider 110 may return to its original position while the attachment of the contact member 120 and the magnetic member 150 is released.

[0125] like Fig.17 As shown, when the door 30 is partially opened, when the roller 61 of the elastic rod 60 moves from the sliding member 110 (see Fig.12 and Fig.13 ) When the receiving force reaches the point where the roller 61 passes the second contact surface 77 and does not exceed the inflection point 73, but is stuck on the inflection point 73, the door 30 will no longer be opened and can be maintained in a partially open state.

[0126] like Fig.18 As shown, when the door 30 stops in a state where the door 30 is only partially opened by the sliding member 110, the sliding member 110 may automatically move backward and return to the original position. That is, the sliding member 110 may return to the position when the door 30 is closed. However, the present disclosure is not limited thereto, and when the door 30 stops in a state where the door 30 is only partially opened by the sliding member 110, the sliding member 110 may move backward and return to the original position by the manipulation of the user. For example, the user may touch a switch or the like to operate the sliding member 110 to move backward.

[0127] like Fig.19 As shown, when the slider 110 moves backward, since the contact member 120 and the magnetic member 150 of the slider 110 are maintained in a state of being attached to each other, the door 30 can rotate in the closing direction due to the magnetic force of the magnets 121 and 180. That is, the door 30 can rotate about the hinge shaft 35 (see Figure 5 ) is rotated counterclockwise. At this time, the cover 190 of the magnetic component 150 can rotate around the pair of rotating protrusions 173, so that the attachment of the cover 190 and the contact component 120 can be maintained according to the closing of the door 30. The cover 190 of the magnetic component 150 can rotate around the pair of rotating protrusions 173, so that the contact component 120 and the magnetic component 150 can be kept parallel to each other for surface contact according to the closing of the door 30. That is, the cover 190 of the magnetic component 150 can rotate around the pair of rotating protrusions 173 at an angle corresponding to the closing angle of the door 30, so that the contact component 120 and the magnetic component 150 can be kept parallel to each other for surface contact according to the closing of the door 30. That is, when the door 30 is closed in a state where the contact component 120 is attached to the magnetic component 150, the cover 190 of the magnetic component 150 can rotate so that the contact component 120 is closed while keeping the attachment surface attached to the magnetic component 150. Because the door 30 rotates around the hinge shaft 35 (see Figure 5 ) rotates counterclockwise, so the cover 190 can rotate clockwise around a pair of rotating protrusions 173.

[0128] like Fig. 20 As shown, when the slider 110 moves backward and the door 30 is completely closed, the attachment of the contact member 120 of the slider 110 and the magnetic member 150 is released, and the slider 110 can return to the original position.

[0129] Fig.21 2 is a view showing that the magnetic member according to the embodiment is provided with a magnet and the contact member is not provided with a magnet but is provided with a cover made of iron.

[0130] like Fig.21 As shown, the magnet 180 may be provided only on the magnetic member 150. In this case, the cover 122 of the contact member 120 may be formed of iron so that the contact member 120 may be attached to the magnetic member 150. In addition to the cover 122 for fixing the magnet 121 (see Figure 6 ) of the fixing hook 142 (see Figure 6 ) is deleted, the structure of the housing 140 may be the same as the structure of the housing 140 shown in FIG. 6. Except for the structure of the housing 140, the remaining structure of the sliding member 110 may be the same as that in FIG. Figure 6 The construction of the slide 110 shown in FIG. 1 is the same.

[0131] Fig. 22 1 is a view showing that a contact member according to an embodiment is provided with a magnet and a magnetic member is not provided with a magnet but is provided with a cover made of iron.

[0132] like Fig. 22 As shown, the magnet 121 may be provided only on the contact member 120. In this case, the cover 190 of the magnetic member 150 may be formed of iron so that the contact member 120 may be attached to the magnetic member 150. In addition to the cover 190 for fixing the magnet 180 (see Figure 7 ) of a pair of fixing hooks 191 (see Figure 7 ) is deleted, the cover 190 may be constructed in the same manner as in Figure 7 The construction of the cover 190 shown in FIG. 1 is the same as that of the cover 190 shown in FIG. 1. Except for the construction of the cover 190, the remaining construction of the magnetic component 150 may be the same as that of FIG. Figure 7 and Figure 8 The construction of the magnetic component 150 shown in FIG. 1 is the same.

[0133] Fig.23 is an exploded view showing a slide according to an embodiment.

[0134] like Fig.23 As shown, the slider 110 may include a contact member 120 disposed at the front end of the slider 110. When the slider 110 moves forward, the contact member 120 may be attached to the magnetic member 150 assembled to the rear surface 39 of the door 30, and push the magnetic member 150 in a state where the contact member 120 is attached to the magnetic member 150. When the contact member 120 pushes the magnetic member 150, the door 30 may be partially opened (see Fig.11 ).

[0135] The contact member 120 may include a magnet 124. When the slider 110 moves forward, the magnet 124 may attach the contact member 120 to the magnetic member 150 by magnetic force. The closing force of the door 30 may be adjusted by adjusting the size and / or thickness of the magnet 124.

[0136] The contact member 120 may include a cover 125 rotatably assembled to the front of the housing 140, which will be described below. The cover 125 may cover the magnet 124 to prevent the magnet 124 from being exposed to the outside. In addition, the cover 125 may prevent the magnet 124 from directly contacting the magnetic member 150.

[0137] The cover 125 may include a pair of fixing hooks 126 to which the magnet 124 is fixed. The pair of fixing hooks 126 may be formed on the left and right sides of the cover 125, respectively. Since the magnet 124 is fixed to the pair of fixing hooks 126 formed on the cover 125, the magnet 124 may rotate together with the cover 125. In addition, since the magnet 124 is fixed to the inside of the cover 125, the magnet 124 may be prevented from being exposed to the outside by the cover 125. The magnet 124 may be prevented from directly contacting the magnetic member 150 by the cover 125.

[0138] The cover 125 may include a pair of rotation holes 127 into which a pair of rotation protrusions 144 formed on the housing 140 are rotatably assembled. The pair of rotation holes 127 may be formed at upper and lower portions of the cover 125 to correspond to the pair of rotation protrusions 144, respectively.

[0139] The slide 110 may include a rack 130 configured to allow the slide 110 to move in the front-rear direction. The rack 130 is engaged with a pinion gear, and the pinion gear may be rotated by a motor. Therefore, when the pinion gear is rotated by the motor, the rack 130 may move in the front-rear direction according to the rotation direction of the pinion gear.

[0140] The slider 110 may include a housing 140 in which the magnet 124 is accommodated. The housing 140 may be provided at a front end of the slider 110. The housing 140 may include an open opening 143 so that the magnet 124 is accommodated in the housing 140.

[0141] The housing 140 may include a pair of rotating protrusions 144, and the cover 125 is rotatably assembled to the pair of rotating protrusions 144. The pair of rotating protrusions 144 may be formed to protrude from the upper and lower portions of the housing 140, respectively. The pair of rotating protrusions 144 may be formed within the housing 140 at a portion that is away from the hinge shaft 35 of the door 30 in the left-right direction relative to the center of the housing 140. The cover 125 may rotate in the left-right direction around the pair of rotating protrusions 144. However, as described above, the pair of rotating protrusions 144 is not limited to being formed within the housing 140 at a portion that is away from the hinge shaft 35 of the door 30 in the left-right direction relative to the center of the housing 140. That is, the pair of rotating protrusions 144 may be formed within the housing 140 at a portion that is close to the hinge shaft 35 of the door 30 in the left-right direction relative to the center of the housing 140 (see Figure 5 ).

[0142] As described above, since the cover 125 rotates in the left-right direction about the pair of rotating protrusions 144 when the door 30 is opened or closed, the contact member 120 rotates according to the angle at which the door 30 is opened or closed, so that the attachment of the contact member 120 and the magnetic member 150 can be maintained. That is, when the door 30 is opened or closed, the cover 125 of the contact member 120 rotates at an angle corresponding to the angle at which the door 30 is opened or closed, so that the attachment of the contact member 120 and the magnetic member 150 can be maintained. That is, when the door 30 is opened or closed, the cover 125 of the contact member 120 can be rotated so that the door 30 is opened or closed while the contact member 120 keeps the attachment surface attached to the magnetic member 150. In the case where the cover 125 does not rotate according to the angle at which the door 30 is opened or closed when the door 30 is opened or closed, since the attachment of the contact member 120 and the magnetic member 150 can be maintained, but the contact member 120 and the magnetic member 150 may not be maintained parallel, only a portion of the attachment can be maintained instead of maintaining surface contact. Therefore, in the case where the cover 125 rotates according to the angle at which the door 30 is opened or closed when the door 30 is opened or closed, the contact member 120 and the magnetic member 150 are maintained in a parallel state, and surface contact can be maintained completely.

[0143] Fig.24 is a diagram for explaining a process of assembling a disassembled magnetic component to a rear surface of a door according to an embodiment.

[0144] like Fig.24 As shown, the magnetic component 150 may include a housing 160 having an open front and assembled to the rear surface 39 of the door 30. The magnetic component 150 may include a shell 170 having an open front and fixed to the interior of the housing 160. The magnetic component 150 may include a magnet 180 partially accommodated in the shell 170. The magnetic component 150 may include a cover 195, which is configured to be assembled to the front of the shell 170 to cover the open front of the shell 170.

[0145] The housing 160 may be assembled to the rear surface 39 of the door 30. In order to assemble the housing 160, the door 30 may include an insertion hole 51 formed to allow a portion of the housing 160 to be inserted into the rear surface 39 of the door 30. The rear portion of the housing 160 may be inserted into the insertion hole 51 formed on the rear surface 39 of the door 30.

[0146] The door 30 may include a pair of assembly grooves 53 formed at the upper and lower portions of the insertion hole 51, respectively, to allow assembly of a portion of the housing 160 inserted into the insertion hole 51. The pair of assembly grooves 53 may be formed along the edge of the insertion hole 51 at the upper and lower portions of the insertion hole 51, respectively. The assembly groove 53 formed at the upper portion of the insertion hole 51 among the pair of assembly grooves 53 may be formed such that opposite ends of the assembly groove extend to portions on the left and right sides of the insertion hole 51. The assembly groove 53 formed at the lower portion of the insertion hole 51 among the pair of assembly grooves 53 may be formed such that opposite ends of the assembly groove extend to portions on the left and right sides of the insertion hole 51.

[0147] The door 30 may include a pair of assembling portions 55 formed on left and right sides of the insertion hole 51 , respectively, to allow assembling a portion of the housing 160 inserted into the insertion hole 51 .

[0148] The housing 160 may include a pair of assembly ribs 161 configured to be assembled by being fitted into a pair of assembly grooves 53 formed on the rear surface 39 of the door 30. The pair of assembly ribs 161 may be formed at the rear edge portion of the housing 160 to protrude rearward. That is, the pair of assembly ribs 161 may be formed to protrude toward the pair of assembly grooves 53 in which the pair of assembly ribs 161 are fitted and assembled (see FIG. Figure 8 ).

[0149] The housing 160 may include a pair of assembling hooks 163 configured to be assembled by fitting into a pair of assembling portions 55 formed on the rear surface 39 of the door 30. The pair of assembling hooks 163 may be formed on left and right sides of the housing 160, respectively.

[0150] The housing 160 may include a plurality of fixing grooves 165 to which the housing 170 is fixed. The plurality of fixing grooves 165 may be formed inside the housing 160 so as to fix the housing 170 to the inside of the housing 160. The plurality of fixing grooves 165 may be formed on the upper surface, the lower surface, the left surface, and the right surface of the inside of the housing 160, respectively.

[0151] The magnetic member 150 may include a housing 170 having an open front and fixed to the inside of the housing 160. The housing 160 may include a receiving portion 167 in which the housing 170 is received by having an open front. The housing 170 may include an opening 174 configured to receive a portion of the magnet 180.

[0152] The housing 170 may include a plurality of housing fixing hooks 175, and the plurality of housing fixing hooks 175 are provided to be fixed to a plurality of fixing grooves 165 formed in the housing 160. The plurality of housing fixing hooks 175 may be formed on the upper surface, the lower surface, the left surface, and the right surface of the outer side of the housing 170 to respectively correspond to the plurality of fixing grooves 165. By fixing the plurality of housing fixing hooks 175 to the plurality of fixing grooves 165, the housing 170, which may be accommodated in the accommodation portion 167 of the housing 160, may be fixed to the inside of the housing 160.

[0153] The magnetic member 150 may include a magnet 180. When the slider 110 moves forward, the magnet 180 may attach the contact member 120 to the magnetic member 150 by magnetic force. The closing force of the door 30 may be adjusted by adjusting the size and / or thickness of the magnet 180.

[0154] The magnetic component 150 may include a cover 195 rotatably assembled to the front of the housing 170. The cover 195 may cover the open front of the housing 170. The cover 195 may include a pair of fixing hooks 196 to which the magnet 180 is fixed. The pair of fixing hooks 196 may be formed on the left and right sides of the cover 195, respectively. Since the magnet 180 is fixed to the inside of the cover 195, the magnet 180 may be prevented from being exposed to the outside by the cover 195. The magnet 180 may be prevented from directly contacting the contact part 120 of the sliding member 110 by the cover 195.

[0155] Fig.25 is a diagram illustrating a state in which a contact member is attached to a magnetic member when a slider moves forward in a state in which a door is closed according to an embodiment. Fig.26 It is shown that due to Fig.25 FIG. 2 shows a diagram of a cover of a contact part being rotated when a sliding member in the door is moved forward and a door is opened.

[0156] like Fig.25 As shown, when the door 30 is closed, the first switch 41 (see Figure 3 ) is touched to operate the slider 110, the slider 110 moves forward so that the contact member 120 can be attached to the magnetic member 150. That is, the magnet 124 of the contact member 120 and the magnet 180 of the magnetic member 150 can be attached by magnetic force. In this case, the magnet 124 of the contact member 120 and the magnet 180 of the magnetic member 150 can be prevented from directly contacting each other by the covers 125 and 195, respectively.

[0157] like Fig.26As shown, when the slider 110 moves further forward in a state where the contact member 120 is attached to the magnetic member 150, the contact member 120 pushes the magnetic member 150, so that the door 30 is partially opened. At this time, the cover 125 of the contact member 120 can rotate around a pair of rotating protrusions 144 so that the attachment to the magnetic member 150 can be maintained according to the opening of the door 30. The cover 125 of the contact member 120 can rotate around a pair of rotating protrusions 144 so that the contact member 120 and the magnetic member 150 can be maintained parallel to each other to make surface contact with each other according to the opening of the door 30. That is, the cover 125 of the contact member 120 can rotate around a pair of rotating protrusions 144 at an angle corresponding to the opening angle of the door 30, so that the contact member 120 and the magnetic member 150 can be maintained parallel to each other to make surface contact with each other according to the opening of the door 30. Because the door 30 rotates around the hinge shaft 35 (see Figure 5 ) rotates clockwise, so the cover 125 can rotate clockwise around a pair of rotating protrusions 144.

[0158] Although not shown in the drawings, when the contact member 120 and the magnetic member 150 are maintained in a parallel state according to the opening and closing of the door 30, both the contact member 120 and the magnetic member 150 may be rotated according to the opening and closing of the door 30. In addition, both the contact member 120 and the magnetic member 150 may not be rotated. When neither the contact member 120 nor the magnetic member 150 rotates, the slider 110 may be formed to have the same track as the track along which the door 30 rotates according to the opening and closing of the door 30. That is, the slider 110 is formed in an arc shape with a curvature instead of a straight bar, so that the slider 110 can move along the same track as the track along which the door 30 rotates.

[0159] Although specific shapes and directions are mainly described with reference to the accompanying drawings in the description of the refrigerator, those skilled in the art may make various modifications and changes to these shapes and directions, and these modifications and changes will be construed as being included within the scope of the rights of the present disclosure.
