REFRIGERATOR

Description

Technical Field

[0001] The present invention relates to a refrigerator, and more particularly, to an ice bank for a refrigerator capable of storing ice pieces therein.

Background Art

[0002] Generally, a refrigerator serves to freshly store food items for a long time in a frozen state or in a cooled state.

[0003] The refrigerator is provided with a refrigerator body divided into a freezing chamber and a refrigerating chamber. The refrigerator body is provided with a freezing chamber door and a refrigerating chamber door through which the freezing chamber and the refrigerating chamber are opened or closed. The freezing chamber door and the refrigerating chamber door are respectively installed at one side of the refrigerator body, such that one ends thereof are rotatable in back and forth directions of the refrigerator body centering around another ends thereof.

[0004] At each one side of the freezing chamber door and the refrigerating chamber door, provided are supplementary storage chambers (hereinafter, will be referred to as home bars) for storing and drawing out food items without opening the freezing chamber door or the refrigerating chamber door.

[0005] The home bar is composed of a home bar housing disposed on a rear surface of the freezing chamber door or the refrigerating chamber door with a storage space, and a home bar door for opening and closing the storage space.

[0006] The home bar door serves to open or close an opening formed as a part of the freezing chamber door or the refrigerating chamber door corresponding to the home bar housing is cut out. The home bar door is installed such that an upper end thereof is rotatable in up and down directions centering around a lower end thereof.

[0007] The freezing chamber is provided with an ice-making device for making ice pieces. And, the freezing chamber may be also provided with an ice bank for storing ice pieces made by the ice-making device. However, the conventional ice bank has the following problems.

[0008] Firstly, in order to draw out the ice bank for storing ice pieces made by the ice-making device, the freezing chamber has to be opened by rotating the freezing chamber door. This may cause a difficulty in drawing out the ice bank.

[0009] Secondly, once the freezing chamber is opened in order to draw out the ice bank, cool air inside the freezing chamber is leaked out. As cool air inside the freezing chamber is unnecessarily leaked out, power consumption of the refrigerator is increased.

[0010] Thirdly, since the ice bank is accommodated in the freezing chamber, ice pieces in the ice bank may be soaked with odor of other food items stored in the freezing chamber.

[0011] Fourthly, since the ice bank is provided in the refrigerating chamber with a limited volume, the ice-making device has to make ice pieces a plurality of times when a large amount of ice pieces are required in summer, for example. WO2007094554 discloses a refrigerator according to the preamble of claim 1. KR20050058001 discloses a volume changeable ice storage box for refrigerator.

Disclosure of Invention

Technical Problem

[0012] Therefore, it is an object of the present invention to provide a refrigerator capable of easily drawing out ice pieces, and controlling an amount of ice pieces to be stored according to a user s necessity.

Technical Solution

[0013] To achieve these and other advantages and in accordance with the present invention, there is provided a refrigerator according to claim 1.

Advantageous Effects

[0014] The refrigerator according to the present invention has the following advantages.

[0015] A volume of the ice bank is varied according to a user s necessity. This may solve a user s inconvenience to make ice pieces a plurality of times, for example, in summer when a large amount of ice pieces are required.

[0016] Also, ice pieces stored in the ice bank are take out through the home bar. This may enable the ice bank to be drawn out of the refrigerator in a state that the door is not opened. Accordingly, a user can easily take ice pieces out of the refrigerator.

[0017] Furthermore, the ice bank is drawn out of the refrigerator through the home bar by downward slantly moving. This may prevent food items stored in the home bar from being drawn out with interfering with the ice bank, or prevent the ice bank from being drawn out with interfering with ice pieces stored therein.

[0018] Futhermore, the ice bank is installed at a predetermined space on a rear surface of the freezing chamber door. This may prevent the ice pieces stored in the ice bank from being soaked with odor of food items stored in the ice storage space of the refrigerator. Accordingly, a user may use the ice pieces in a sanitary and comfortable manner.

[0039] When the ice pieces made by the ice-making device 22 are to be transferred to the ice bank 100, the positions of the ice-making device 22 and the water box 21 may be changed.

[0040] Hereinafter, the ice bank 100 will be explained in more detail.

[0041] FIG. 3 is a sectional view taken along line I-I in FIG. 1, FIG. 4 is a perspective view showing a mounted state of an ice bank of FIG. 3, and FIG. 5 is a perspective view showing the ice bank of FIG. 4 and a second guide portion.

[0042] Referring to FIGS. 3 to 5, the ice bank 100 is installed at the storage space 15s of the home bar housing 15a, so as to be drawn out of the storage space 15s of the home bar housing 15a through the opening 15c. The ice bank 100 comprises a body portion 110 formed in a hexahedron shape having opened upper and lower surfaces; and a volume expansion container 120 inserted into the body portion 110 so as to be vertically moveable along an inner surface of the body portion 110, and forming an ice storage space 100s having an opened upper surface.

[0043] Preferably, one surface of the ice bank 100 is formed of a transparent or a semitransparent material such that ice pieces stored in the ice storage space 100s can be recognized from outside.

[0044] A handgrip 101 may be provided at the ice bank 100 between a front surface of the body portion 110 and a front surface of the volume expansion container 120. The handgrip 101 may be formed to be concaved from a lower end of the front surface of the volume expansion container 120 toward a rear surface of the volume expansion container 120 by a predetermined height. Hereinafter, it is assumed that the front surface of the ice bank 100 indicates one surface of the ice bank 100 viewed from a front surface of the freezing chamber door 11a, i.e., one surface of the ice bank 100 viewed when the storage space 15s of the home bar housing 15a is opened by the home bar door 15b.

[0045] The ice bank 100 is installed at the storage space 15s of the home bar housing 15a by a guide unit.

[0046] The guide unit includes a first guide portion 140 fixed in the opening 15c for guiding the ice bank 100 to downward slantly move toward the opening 15c; and a second guide portion 150 drawn out of the opening 15c under guide of the first guide portion 140 for mounting the ice bank 100 in a drawing manner.

[0047] A process for coupling the first guide portion 140 and the second guide portion 150 with each other will be explained in more detail.

[0048] The first guide portion 140 guides the second guide portion 150 having the ice bank 100 mounted thereto to downward slantly move toward the opening 15c, the opened front surface of the first guide portion 140.

[0049] The first guide portion 140 prevents ice pieces stored in the ice storage space 100s of the ice bank 100 from being locked by the rear surface of the freezing chamber door 11a adjacent to the opening 15c, in the process that the ice bank 100 and the second guide portion 150 are drawn out of the storage space 15s of the home bar housing 15a.

[0050] In order to guide the ice bank 100 and the second guide portion 150 to downward slantly move toward the opening 15c, one pair of guide slots 141 are provided at both side surfaces of the first guide portion 140.

[0051] One pair of guide protrusions 151 are protruding from both side surfaces of the second guide portion 150.

[0052] The guide protrusions 151 serve to guide the second guide portion 150 to be drawn out of the storage space 15s of the home bar housing 15a through the opening 15c in a state that the ice bank 100 is mounted to the second guide portion 150.

[0053] The guide protrusions 151 perform a sliding motion along the guide slots 141 in an inserted state into the guide slots 141 of the first guide portion 140.

[0054] The guide protrusions 151 are composed of a first guide protrusion 152 and a second guide protrusion 153. The first guide protrusion 152 is protruding from upper middle portions of both sides of the second guide portion 150, respectively.

[0055] The second guide protrusion 153 is protruding from rear middle portions of both sides of the second guide portion 150, respectively, with a lower height than the first guide protrusion 152. More concretely, the first guide protrusion 152 and the second guide protrusion 153 are spacing from each other by a predetermined distance in a direction that the ice bank 100 and the second guide portion 150 are drawn out of the storage space 15s of the home bar housing 15a through the opening 15c.

[0056] The reason is in order to allow the ice bank 100 and the second guide portion 150 to maintain a horizontal state when accommodated in the storage space 15s of the home bar housing 15a.

[0057] The first guide portion 140 serves to guide the second guide portion 150 drawn out of the storage space 15s of the home bar housing 15a in a state that the ice bank 100 is mounted to the second guide portion 150.

[0058] The first guide portion 140 is formed in a hexahedron shape having opened front, rear, and lower surfaces. The second guide portion 150 is installed in the first guide portion 40 so as to be drawn out in a front direction.

[0059] An ice transfer opening 144 is provided on an upper surface of the first guide portion 140. The ice transfer opening 144 serves as a passage through which ice pieces made by the ice-making device 22 are supplied to the ice storage space 100s of the ice bank 100. The ice transfer opening 144 is formed as an upper surface of the first guide portion 140 is opened. The ice transfer opening 144 is formed in a rectangular shape having a size equal to or less than an opened upper portion of the ice bank 100, i.e., an inlet of the ice storage space 100s.

[0060] An ice transfer guide portion 145 is provided on an upper surface of the first guide portion 140 corresponding to the edge of the ice transfer opening 144. The ice transfer guide portion 145 is formed in a hopper shape that two side surfaces thereof are downward slanted toward the ice transfer opening 144. The ice transfer guide portion 145 serves to guide ice pieces made by the ice-making device 22 so as to be supplied to the ice storage space 100s of the ice bank 100 through the ice transfer opening 144.

[0061] Fixing grooves 147 are formed on both side surfaces of the first guide portion 140. The fixing grooves 147 serve to fix the first guide portion 140. To the fixing groove, inserted is a fixing protrusion (not shown) disposed at the supporting side wall 11b of the freezing chamber door 11a, and protruding to the storage space 15s of the home bar housing 15a.

[0062] The guide slots 141 are composed of a first guide slot 142 along which the first guide protrusion 152 inserted therein perform a sliding motion, and a second guide slot 143 along which the second guide protrusion 153 inserted therein perform a sliding motion.

[0063] The first guide slot 142 is composed of a first horizontal section 142a, an inclined section 142b, and a second horizontal section 142c.

[0064] The first horizontal section 142a is horizontally extending by a predetermined length, from upper middle portions of both side surfaces of the first guide portion 140, respectively, toward a direction that the second guide portion 150 having the ice bank 100 mounted thereto is drawn out, i.e., toward front ends of both side surfaces of the first guide portion 140.

[0065] The inclined section 142b is downward slantly extending by a predetermined length, from a front end of the first horizontal section 142a, to a direction that the second guide portion 150 having the ice bank 100 mounted thereto is drawn out.

[0066] The second horizontal section 142c is horizontally extending by a predetermined length, from a front end of the inclined section 142b, to a direction that the second guide portion 150 having the ice bank 100 mounted thereto is drawn out. A front end of the second horizontal section 142c is respectively located at middle portions of front ends of both side surfaces of the first guide portion 140.

[0067] The second guide slot 143 is composed of a first horizontal section 143a, an inclined section 143b, and a second horizontal section 143c.

[0068] The first horizontal section 143a is horizontally extending by a predetermined length, from rear middle portions of both side surfaces of the first guide portion 140, respectively, toward a direction that the second guide portion 150 having the ice bank 100 mounted thereto is drawn out, i.e., toward front ends of both side surfaces of the first guide portion 140.

[0069] The inclined section 143b is downward slantly extending by a predetermined length, from a front end of the first horizontal section 143a, to a direction that the second guide portion 150 having the ice bank 100 mounted thereto is drawn out.

[0070] The second horizontal section 143c is horizontally extending by a predetermined length, from a front end of the inclined section 143b, to a direction that the second guide portion 150 having the ice bank 100 mounted thereto is drawn out. A front end of the second horizontal section 143c is located at lower front ends of both side surfaces of the first guide portion 140, respectively.

[0071] Accordingly, when the second guide portion 150 having the ice bank 100 mounted thereto is located in the first guide portion 140, i.e., when the second guide portion 150 is accommodated in the storage space 15s of the home bar housing 15a, the first guide protrusion 152 and the second guide protrusion 153 are located at a rear end of the first horizontal section 142a of the first guide slot 142, and a rear end of the first horizontal section 143a of the second guide slot 143, respectively.

[0072] Here, the ice bank 100 and the second guide portion 150 in a horizontal state with respect to each other are disposed to be adjacent to the ice transfer opening 144 of the first guide portion 140 therebelow, and to an upper end of the opening 15c.

[0073] Then, once the second guide portion 150 having the ice bank 100 mounted thereto is moved towards the opening 15c, the first guide protrusion 152 and the second guide protrusion 153 slide along the inclined section 142b of the first guide slot 142 and the inclined section 143b of the second guide slot 143, respectively.

[0074] Accordingly, the second guide portion 150 is downward slantly moved toward the opening 15c. Here, upper surfaces of the ice bank 100 and the second guide portion 150 are downward spacing, by a predetermined distance, from the upper end of the ice transfer opening 144 of the first guide portion 140 and the opening 15c.

[0075] When the second guide portion 150 having the ice bank 100 mounted thereto continues to move toward the opening 15c, the first guide protrusion 152 and the second guide protrusion 153 slide along the second horizontal section 142c of the first guide slot 142, and the second horizontal section 143c of the second guide slot 143.

[0076] Once the first guide protrusion 152 and the second guide protrusion 153 are positioned on a front end of the second horizontal section 142c of the first guide slot 142, and on a front end of the second horizontal section 143c of the second guide slot 143, respectively, front ends of the second guide portion 150 and the ice bank 100 mounted to the second guide portion 150 are partially drawn out of the storage space 15s of the home bar housing 15a through the opening 15c.

[0077] In the present invention, the ice bank 100 mounted to the second guide portion 150 is guided by the first guide portion 140.

[0078] However, it may be configured that the ice bank 100 is directly guided by the first guide portion 140 without being mounted to the second guide portion 150.

[0079] In this case, in order to draw the ice bank 100 out of the storage space 15s of the home bar housing 15a, front ends of the guide slots 141 of the first guide portion 140, i.e., the second horizontal sections 142c and 143c are formed to be outwardly opened through front ends of both side surfaces of the first guide portion 140.

[0080] A process for coupling the second guide portion 150 and the ice bank 100 will be explained in more detail with reference to FIG. 5.

[0081] Referring to FIG. 5, the ice bank 100 comprises a body portion 110 formed in a box shape having opened upper and lower surfaces; and a volume expansion container 120 inserted into the body portion 110 so as to be vertically moveable along an inner surface of the body portion 110, and forming an ice storage space 100s having an opened upper surface.

[0082] The second guide portion 150 is formed in a hexahedron shape of which upper, lower, and front surfaces are opened in correspondence to the body portion 110.

[0083] The second guide portion 150 having the ice bank 100 mounted thereto is drawn out of the storage space 15s of the home bar housing 15a, through the opening 15c under guide of the first guide portion 140. And, the ice bank 100 is drawn out of the storage space 15s of the home bar housing 15a, through the opening 15c under guide of the second guide portion 150.

[0084] Locking ribs 115 are provided on a front surface of the ice bank 100. And, interworking protrusions 113 are provided at upper rear portions of both side surfaces of the ice bank 100.

[0085] Supporting portions 155 for supporting the ice bank 100 are extending from lower ends of both side surfaces of the second guide portion 150 in a thickness direction of the body portion 110. Interworking ribs 154 are extending from upper front ends of both side surfaces of the second guide portion 150, by a predetermined length, so as to face each other in a thickness direction of the body portion 110.

[0086] The locking ribs 115 are downward extending from lower front ends of the ice bank 100 by a predetermined length, and are extending in right and left directions of the front surface of the ice bank 100.

[0087] The interworking protrusions 113 are upward protruding, by a predetermined height, from upper rear ends of both side surfaces of the ice bank 100.

[0088] The locking ribs 115 and the interworking protrusions 113 serve to move the second guide portion 150 by interworking with the ice bank 100 that moves in a direction to be drawn out of the storage space 15s of the home bar housing 15a through the opening 15c.

[0089] For this, the locking ribs 115 and the interworking protrusions 113 are adhered to front ends of both side surfaces of the second guide portion 150, and rear ends of the interworking ribs 154 of the second guide portion 150, respectively.

[0090] Inclined portions 111 are provided at lower rear ends of both side surfaces of the body portion 110.

[0091] The inclined portions 111 are downward slanted toward a direction that the ice bank 100 is drawn out of the storage space 15s of the home bar housing 15a through the opening 15c. The inclined portions 111 serve to detach the ice bank 100 having been drawn out of the storage space 15s of the home bar housing 15a through the opening 15c, from the second guide portion 150, by upward slantly moving the ice bank 100 with a mounted state to the second guide portion 150.

[0092] Once the ice bank 100 is moved in a direction to be accommodated in the storage space 15s of the home bar housing 15a, the locking ribs 115 push a front end of a bottom surface of the second guide portion 150. This allows the second guide portion 150 to be accommodated in the ice bank 100 by interworking with the ice bank 100.

[0093] Then, when the ice bank 100 is moved in a direction to be drawn out of the storage space 15s of the home bar housing 15a through the opening 15c, the interworking protrusions 113 are adhered to rear ends of the interworking ribs 154 to push the interworking ribs 154. This allows the second guide portion 150 to be drawn out of the ice bank 100 by interworking with the ice bank 100.

[0094] In the present invention, when the ice bank 100 is moved in a direction to be accommodated in the storage space 15s of the home bar housing 15a, the second guide portion 150 interworks with the ice bank 100 by the locking ribs 115, and is accommodated in the ice bank 100 under guide of the first guide portion 140.

[0095] It may be also configured that when the ice bank 100 is moved in a direction to be accommodated in the storage space 15s of the home bar housing 15a, the second guide portion 150 interworks with the ice bank 100 as a rear surface thereof is pushed by a rear surface of the ice bank 100.

[0096] Hereinafter, will be explained a volume control unit 130 for changing a volume of the ice bank 100 step by step.

[0097] FIG. 6 is an exploded perspective view showing the ice bank and the second guide portion of FIG. 5.

[0098] Referring to FIG. 6, the volume control unit 130 controls a volume of the ice bank 100 by restricting a relative motion of the volume expansion container 120 with respect to the body portion 110 step by step.

[0099] The volume control unit 130 includes volume control grooves 131 formed at one of inner side surfaces of the body portion 110 and outer side surfaces of the volume expansion container 120; volume control protrusions 132 formed at another of the inner side surfaces of the body portion 110 and the outer side surfaces of the volume expansion container 120; and a locking unit 133 and 134 for restricting a relative motion of the volume control grooves 131 and the volume control protrusions 132 step by step.

[0100] Referring to FIG. 6, the volume control grooves 131 are formed at the volume expansion container 120, whereas the volume control protrusions 132 are formed at the body portion 110. However, the positions of the volume control grooves 131 and the volume control protrusions 132 may be interchanged to each other.

[0101] The volume control grooves 131 are formed at outer side surfaces of the volume expansion container 120 in a consecutive manner from an upper end to a lower end of the volume expansion container 120. That is, the volume control grooves 131 are formed in a volume control direction of the ice bank 100.

[0102] The volume control grooves 131 may be formed by partially reducing a thickness of both side surfaces of the volume expansion container 120. However, in order to prevent lowering of a strength of the ice bank 100 stored in a lower temperature, it is preferable to inwardly curve parts of both side surfaces of the volume expansion container 120.

[0103] Preferably, the volume control grooves 131 are formed such that upper ends thereof are closed. The reason is in order to prevent separation of the body portion 110 from the volume expansion container 120, occurring as the volume control protrusions 132 moving along the volume control grooves 131 are detached from an upper end of the volume expansion container 120 when a volume of the ice bank 100 is to be maximized.

[0104] The volume control protrusions 132 are formed at the inner side surfaces of the body portion 110 in correspondence to the volume control grooves 131.

[0105] In order to maximize a volume of the ice bank 100, the volume control protrusions 132 are preferably formed at lower ends of the inner side surfaces of the body portion 110.

[0106] The locking unit includes locking grooves 133 formed at one of the volume control grooves 131 and the volume control protrusions 132 in a volume control direction of the ice bank 100, and locking protrusions 134 formed at another of the volume control grooves 131 and the volume control protrusions 132 and locked by the locking grooves 133 step by step.

[0107] Referring to FIG. 6, the locking grooves 133 are provided at the volume control grooves 131 with a predetermined gap therebetween in plurality in a volume control direction of the ice bank 100. And, the locking protrusions 134 are formed at the volume control protrusions 132.

[0108] However, the positions of the locking grooves 133 and the locking protrusions 134 may be interchanged to each other.

[0109] The locking grooves 133 are formed on either inner surfaces of the volume control grooves 131, or both side surfaces of the volume control grooves 131. And, the locking grooves 133 are formed so as to be opened in a direction that the ice bank 100 is drawn out.

[0110] The locking protrusions 134 are formed on side surfaces of the volume control protrusions 132 in correspondence to the locking grooves 133.

[0111] The locking protrusions 134 are formed so as to be elastically supported in a direction perpendicular to a volume control direction of the ice bank 100.

[0112] In the present invention, the locking protrusions 134 are implemented as plate springs supported by inner side walls of the volume control protrusions 132. However, the locking protrusions 134 may be configured so as to be supported by compression springs, etc.

[0113] The locking groove 133 is formed such that inner side surfaces thereof are inclined in a volume control direction of the ice bank 100. The reason is in order to guide motion of the locking protrusions 134.

[0114] Accordingly, an upper side of the locking grooves 133 is upward slantly formed toward an upper surface of the volume expansion container 120, whereas a lower side of the locking grooves 133 is downward slantly formed toward a lower surface of the volume expansion container 120.

[0115] Hereinafter, will be explained processed for drawing the ice bank 100 out of the storage space 15s in the refrigerator according to the first embodiment of the present invention.

[0116] FIGS. 7 to 9 are views showing processes for drawing the ice bank out, and for controlling a volume of the ice bank in the refrigerator according to the first embodiment of the present invention.

[0117] Referring to FIG. 7, in order to use ice pieces stored in the ice storage space 100s of the ice bank 100, the home bar door 15b of the home bar 15 is opened to open the opening 15c. Then, the ice bank 100 is pulled out of the storage space 15s of the home bar housing 15a, i.e., in a drawing direction.

[0118] Here, the second guide portion 150 having the ice bank 100 mounted thereto is also moved in the drawing direction by friction to the ice bank 100. The ice bank 100 and the second guide portion 150 are moved under guide of the guide protrusion 151 of the second guide portion 150, and the guide slot 141 of the first guide portion 140.

[0119] More concretely, the second guide portion 150 is horizontally moved in a drawing direction, then is downward slantly moved, and then is horizontally moved, again. Accordingly, even if ice pieces excessively stored in the ice storage space 100s of the ice bank 100 are partially protruding toward an upper side, the ice bank 100 can be drawn out without interfering with the freezing chamber door 11a.

[0120] When the guide protrusions 151 are located at front ends of the guide slots 141, the second guide portion 150 is not moved any longer in the drawing direction.

[0121] As shown in FIG. 9, when the ice bank 100 is continuously pulled in the drawing direction, only the ice bank 100 is moved in the drawing direction to be drawn out of the storage space 15s of the home bar housing 15a through the opening 15c.

[0122] Here, the ice bank 100 is moved in the drawing direction until the interworking protrusions 113 are adhered to rear ends of the interworking ribs 154 of the second guide portion 150. In a state that the interworking protrusions 113 are adhered to the rear ends of the interworking ribs 154, only a part of a front end of the ice bank 100 is drawn out of the storage space 15s of the home bar housing 15a through the opening 15c.

[0123] Under this state, the ice bank 100 is moved so that its front end is upward slanted in the drawing direction. This causes the ice bank 100 to be detached from the second guide portion 150, and to be completely drawn out of the storage space 15s of the home bar housing 15a. Here, the inclined portions 111 serve to prevent the ice bank 100 from interfering with the second guide portion 150 when being separated from the second guide portion 150.

[0124] Hereinafter, a refrigerator according to a second embodiment of the present invention will be explained in more detail with reference to the attached drawings. Detailed explanations for the same structures as those of the first embodiment will be omitted.

[0125] FIG. 10 is an exploded perspective view showing an ice bank and a second guide portion according to a second embodiment of the present invention.

[0126] The refrigerator according to the second embodiment is the same as that according to the first embodiment, except for locking unit 233 and 234 of a volume control unit 230.

[0127] The volume control unit 230 includes volume control grooves 231 formed at one of inner side surfaces of a body portion 210 and outer side surfaces of a volume expansion container 220; volume control protrusions 232 formed at another of the inner side surfaces of the body portion 210 and the outer side surfaces of the volume expansion container 220; and a locking unit 233 and 234 for restricting a relative motion of the volume control grooves 231 and the volume control protrusions 232 step by step.

[0128] The volume control grooves 231 are formed at outer side surfaces of the volume expansion container 220 in a consecutive manner from an upper end to a lower end of the volume expansion container 220. That is, the volume control grooves 231 are formed in a volume control direction of the ice bank 200.

[0129] The volume control grooves 231 are formed as parts of both side surfaces of the volume expansion container 220 are inwardly curved.

[0130] The volume control protrusions 232 are formed at the inner side surfaces of the body portion 210 in correspondence to the volume control grooves 231.

[0131] In order to maximize a volume of the ice bank 200, the volume control protrusions 232 are preferably formed at lower ends of the inner side surfaces of the body portion 210.

[0132] The locking unit includes locking grooves 233 formed at one of the volume control grooves 231 and the volume control protrusions 232 with a sectional surface of a sine wave in a volume control direction of the ice bank 200, and locking protrusions 234 formed at another of the volume control grooves 231 and the volume control protrusions 232 with a sectional surface of a sine wave.

[0133] In the present invention, the locking grooves 233 are consecutively formed in upper and lower directions of the volume expansion container 220. This allows a volume of the ice bank 200 to be variably controlled.

[0134] The locking protrusions 234 are provided in plurality in number in correspondence to the locking grooves 233 formed in consecutive sine waves. This allows a coupling force between the body portion 210 and the volume expansion container 220 to be increased.

[0135] Like in the first embodiment, the locking protrusions 234 are preferably formed so as to be elastically supported in a direction perpendicular to a volume control direction of the ice bank 200.

[0136] Hereinafter, a refrigerator according to a third embodiment of the present invention will be explained in more detail with reference to the attached drawings. Detailed explanations for the same structures as those of the first embodiment will be omitted.

[0137] FIG. 11 is an exploded perspective view showing an ice bank and a second guide portion according to a third embodiment of the present invention.

[0138] Referring to FIG. 11, the volume control unit 330 includes a first controller 331 formed at one of inner side surfaces of a body portion 310 and outer side surfaces of a volume expansion container 320, and having a sectional surface of a sine wave in a volume control direction of the ice bank 300; and a second controller 332 formed at another of the inner side surfaces of the body portion 310 and the outer side surfaces of the volume expansion container 320 so as to be engaged with the first controller 331, and having a sectional surface of a sine wave in the volume control direction of the ice bank 300.

[0139] The volume control unit 330 is formed at the inner side surface of the body portion 310, and the outer side surface of the volume expansion container 320 corresponding to each other. The volume control unit 330 is formed to have a sectional surface of a sine wave in a volume control direction of the ice bank 300.

[0140] As the first controller 331 and the second controller 332 are engaged with each other, the body portion 310 and the volume expansion container 320 are coupled to each other, and the body portion 310 and the volume expansion container 320 perform a relative motion with respect to each other along the sectional surfaces of a sine wave.

[0141] For the relative motion of the body portion 310 and the volume expansion container 320 with respect to each other, a predetermined air gap is preferably formed between the inner side surfaces of the body portion 310 and the outer side surfaces of the volume expansion container 320.

[0142] Hereinafter, a refrigerator according to a fourth embodiment of the present invention will be explained in more detail with reference to the attached drawings. Detailed explanations for the same structures as those of the first embodiment will be omitted.

[0143] FIG. 12 is an exploded perspective view showing an ice bank and the second guide portion according to a fourth embodiment of the present invention.

[0144] Referring to FIG. 12, a volume control unit 430 may be implemented as the volume control unit according to the first embodiment or the second embodiment.

[0145] The volume control unit 430 includes volume control grooves 431 formed at one of inner side surfaces of the body portion 410 and the outer side surfaces of the volume expansion container 420, and a locking unit 433 and 434 for restricting a relative motion of the volume control grooves 431 and the volume control protrusions 432 step by step.

[0146] Referring to FIG. 12 , guide ribs 435 are formed at the inner side surfaces of the body portion 410 in a volume control direction of the ice bank 400. And, guide grooves 436 for guiding the guide ribs 435 are formed at the outer side surfaces of the volume expansion container 420.

[0147] The reason is, in order to prevent a phenomenon that the volume control protrusions 432 are fitted into the volume control grooves 431 not to be moved due to a motion between the body portion 410 and the volume expansion container 420, in the case that an inner surface of the body portion 410 is spacing from an outer surface of the volume expansion container 420 due to a tolerance, etc. when a volume of the ice bank 400 is to be changed.
