[0078] A fan motor 300 may be provided at a side of the blocking casing 100 such that cold air is supplied into the blocking casing 100.

[0079] Specifically, the fan motor 300 may be installed at the upper surface of the blocking casing 100. That is, the fan motor 300 may be mounted to the casing cover 200.

[0080] The fan motor 300 may consist of a fan creating a forced flow of air, and a motor supplying rotational power to the fan.

[0081] The casing cover 200 may be composed of a fixing frame 210 to which the fan motor 300 is mounted; a lower decoration 230 provided at the lower side of the fixing frame 210 and constituting the lower exterior of the casing cover 200; and an upper decoration 250 provided at the upper side of the fixing frame 210 and constituting the upper exterior of the casing cover 200.

[0082] Of course, as described above, the casing cover 200 may be composed of one member or part instead of multiple parts.

[0083] The fixing frame 210 may be configured to have shape and size corresponding to the upper end of the casing body 110, and to have a predetermined thickness.

[0084] An installation depression 212 to which the fan motor 300 is mounted may be formed at the fixing frame 210 by being depressed therefrom. That is, as illustrated in FIG. 4, the installation depression 212 having a predetermined size may be formed at the center part of the upper surface of the fixing frame 210 by being depressed therefrom.

[0085] An installation hole 214 may be formed in the installation depression 212 by passing vertically therethrough such that cold air blown by the fan motor 300 passes through the installation hole 214. That is, as illustrated in FIG. 4, the installation hole 214 having a circular shape may be formed at the lower end of the installation depression 212 by passing vertically therethrough, and an air flow generated by the fan motor 300 may be performed downward through such an installation hole 214.

[0086] The upper decoration 250 may be coupled to the upper side of the fixing frame 210 and may constitute the upper exterior of the fixing frame 210. A vent hole 252 which is a path of cold air to be introduced to the fan motor 300 may be formed vertically through the upper decoration 250.

[0087] More specifically, the vent hole 252 may be formed at the center part of the upper decoration 250 by passing vertically therethrough. Such a vent hole 252 may be formed at a vertical position corresponding to the position of the fan motor 300 and to have a shape corresponding to the shape of fan motor 300.

[0088] In the present disclosure, a case in which the vent hole 252 is formed to have a square shape corresponding to the outer shape of the fan motor 300 is illustrated.

[0089] In addition, at least one vent rib 254 crossing the vent hole 252 may be provided in the vent hole 252. That is, multiple vent ribs may be provided to prevent external foreign matter from being introduced into the upper decoration 250 through the vent hole 252. In the present disclosure, a case in which the multiple vent ribs 254 horizontally crossing the vent hole 252 are provided is illustrated.

[0090] As illustrated in FIG. 4, the vent ribs 254 may be horizontally provided entirely on the upper surface of the upper decoration 250, so the upper surface of the upper decoration 250 may be configured to have a comb pattern shape.

[0091] Specifically, the vent ribs 254 may be provided to be horizontally long on the entirety of the upper surface of the upper decoration 250 as well as in the vent hole 252. That is, the vent ribs 254 may be provided to cross the vent hole 252 to primarily prevent a user's hand or foreign matter from being introduced to the fan motor 300 such that the user's injury or the breakdown of the fan motor is prevented. Furthermore, the vent ribs 254 may be provided at left and right sides of the vent hole 252 such that the upper decoration 250 looks neat to a consumer.

[0092] Each of the vent ribs 254 may be provided slantingly to have a predetermined angle, and when such ribs having a comb pattern shape are provided entirely on the upper surface of the upper decoration 250, the exterior of the upper decoration 250 may look more luxurious compared to an upper decoration without the vent ribs.

[0093] The lower decoration 230 may be provided at the lower side of the fixing frame 210 and may constitute the lower exterior of the casing cover 200. A through hole 232 may be formed vertically through the lower decoration 230, the through hole 232 guiding the cold air moved by the fan motor 300 into the casing body 110.

[0094] As illustrated in FIG. 4, the through hole 232 may be formed to be horizontally long, and may be formed at a vertical position corresponding to the position of the fan motor 300. Additionally, the through hole 232 may include at least two through holes such that the cold air is guided evenly to each portion of the door basket 35.

[0095] In the refrigerator of the present disclosure, the through hole 232 is formed vertically through the rear end (a left end in FIG. 6) of the lower decoration 230. That is, an embodiment in which the through hole 232 is formed to have a slit shape to be long in a direction parallel to the inner surface of the refrigerating compartment door 32 is illustrated.

[0096] Accordingly, when the through hole 232 is formed in the rear end (a left end in FIG. 6) of the lower decoration 230, cold air flown by the fan motor 300 may efficiently flow downward through a gap between the casing body 110 and the door basket 35.

[0097] Alternatively, in a case in which the through hole 232 is formed directly under the fan motor 300, that is, at the center part of the lower decoration 230, cold air may hit the door basket 35 located directly under the fan motor 300 and may be prevented from moving downward.

[0098] In addition, as illustrated in FIG. 6, ribs guiding cold air downward may be provided in the through hole 232. Accordingly, the direction of the cold air may be controlled by the ribs of the through hole 232.

[0099] The upper decoration 250 and the lower decoration 230 may be coupled to each other by a fastening means (234,257). That is, the upper decoration 250 and the lower decoration 230 may be coupled to each other by the fastening means such as a screw 257.

[0100] In addition, when the lower decoration 230 and the upper decoration 250 are coupled to each other by the fastening means, the fastening means (234,257) may be configured to pass through the fixing frame 210. In this case, a separate fastening means may not be required to couple the fixing frame 210 to the lower decoration 230 or the upper decoration 250, and the fixing frame 210 may be simultaneously fastened to the lower decoration 230 and the upper decoration 250 by the fastening means coupling the lower decoration 230 and the upper decoration 250 to each other.

[0101] Holes and protrusions may be formed at the upper decoration 250 and the lower decoration 230 such that the upper decoration 250 and the lower decoration 230 are coupled to each other by the fastening means.

[0102] Specifically, at least one decoration hole 256 through which a fastening means such as a screw 257 passes may be formed vertically through the upper decoration 250, and a coupling protrusion 258 may be formed at the lower part of the decoration hole 256 by protruding downward therefrom.

[0103] The coupling protrusion 258 may be configured to have a cylindrical shape having a hollow inner part such that the screw passes through the coupling protrusion 258.

[0104] A coupling tab 234 may be formed at the lower decoration 230 such that the fastening means such as a screw passes through or is screwed to the coupling tab. Such a coupling tab 234 may be formed by protruding upward from the upper surface of the lower decoration 230.

[0105] In addition, a fixing hole 216 through which the fastening means such as a screw passes may be formed vertically through the fixing frame 210. Of course, the coupling protrusion 258 or the coupling tab 234 may pass through or be received in such a fixing hole 216.

[0106] Additionally, the coupling protrusion 258 and the coupling tab 234 may be formed to have sizes or diameters corresponding to each other such that the coupling protrusion 258 and the coupling tab 234 are in contact with each other, or may be formed to have diameters different from each other such that the coupling protrusion 258 and the coupling tab 234 are installed to doubly overlap each other inside and outside.

[0107] A fastening hook 260 and a fastening hole 220 may be formed at the upper decoration 250 and the fixing frame 210, respectively, the fastening hook 260 and the fastening hole 220 being configured to have shapes corresponding to each other and being fastened to each other. Furthermore, the hook hole 112 may be formed in the casing body 110 such that the fastening hook 260 passes through or is fastened to the hook hole 112.

[0108] Specifically, at least one fastening hook 260 may be formed at the upper decoration 250. That is, multiple fastening hooks 260 may be formed on an edge of the lower surface of the upper decoration 250 by protruding downward therefrom.

[0109] In addition, multiple fastening holes 220 may be formed in the fixing frame 210 such that the fastening hooks 260 are fitted to and coupled to the fastening holes.

[0110] The fastening hooks 260 and the fastening holes 220 may be formed at positions vertically corresponding to each other, and may have shapes corresponding to each other to be fastened to each other. Accordingly, when the fastening hooks 260 are inserted to the fastening holes 220, respectively, the fastening hooks 260 may be prevented from being removed from the fastening holes 220.

[0111] Meanwhile, the upper end of the casing body 110 may be bent inward, and the hook hole 112 through which the fastening hook 260 passes may be formed in the upper end of the casing body 110.

[0112] Accordingly, when the fastening hook 260 of the upper decoration 250 may be fastened to the fastening hole 220 of the fixing frame 210 by passing through the hook hole 112 of the casing body 110 from the upper side thereof, the casing cover 200 may be coupled to and fixed to the upper end of the casing body 110.

[0113] A casing coupling end 114 may be formed at the casing body 110 by protruding therefrom toward the rear side of the refrigerating compartment door 32. The casing coupling end 114 may be a part allowing the casing body 110 to be coupled to the rear surface of the refrigerating compartment door 32.

[0114] Accordingly, a casing coupling part 32a may be formed at the rear surface of the refrigerating compartment door 32, and may have a shape corresponding to the shape of the casing coupling end 114 to be fastened to the casing coupling end 114.

[0115] Each of the casing coupling end 114 and the casing coupling part 32a may be configured to have a hook shape and to be fastened to each other by one touch.

[0116] A wire guide 400 may be formed in the refrigerating compartment door 32, and may be covered by a wire cover 410.

[0117] More specifically, as illustrated in FIG. 4, the wire guide 400 having a predetermined size may be formed at the upper end part of the refrigerating compartment door 32 by being depressed therefrom. Such a wire guide 400 may be a part through which a wire allowing power to be supplied to the fan motor 300 passes.

[0118] In addition, the wire cover 410 may be fastened to the wire guide 400 to cover the wire guide 400, and may function to cover the wire such that the wire passing through the wire guide 400 is not exposed to the outside.

[0119] The wire cover 410 and the installation state thereof are illustrated in FIGS. 7 and 8, respectively. That is, in FIG. 7, a partial enlarged view illustrating a state in which the wire cover 410 is separated from the fixing frame 210 is illustrated, and in FIG. 8, a partial side sectional view illustrating a state in which the wire cover 410 is coupled to the upper decoration 250 is illustrated.

[0120] As illustrated in these drawings, the wire cover 410 may be configured to have a shape corresponding to the shape of the upper end of the refrigerating compartment door 32. That is, as illustrated in the drawings, the side section of the wire cover 410 may be configured to have an L shape corresponding to the protruding shape of the upper part of the refrigerating compartment door 32.

[0121] In addition, cover hooks 412 may be provided at the front end (a right end in FIGS. 7 and 8) of the wire cover 410 such that the cover hooks are fitted and coupled to the refrigerating compartment door 32. Of course, although not illustrated in detail, hook holes to which the cover hooks 412 are fastened may be required to be formed in the rear surface of the refrigerating compartment door 32.

[0122] A coupling rib 414 may be formed at a rear end (a left end in FIGS. 7 and 8) of the wire cover 410 by protruding rearward (to a left side in FIGS. 7 and 8) therefrom. That is, the coupling rib 414 may be formed to have thickness smaller than the thickness of the wire cover 410, and may be a part fitted to the upper decoration 250.

[0123] A cover seating end 270 in which the rear end (the left end in FIGS. 7 and 8) of the wire cover 410 sits may be formed at a front end (a right end in FIGS. 7 and 8) of the upper decoration 250.

[0124] As illustrated in FIG. 7, the cover seating end 270 may be formed to have a predetermined depth by being depressed from the upper surface of the upper decoration 250.

[0125] In addition, a rib hole 272 to which the coupling rib 414 is inserted may be foiled at the left end of the cover seating end 270 (in FIGS. 7 and 8) by passing horizontally therethrough.

[0126] Accordingly, the right end of the wire cover 410 (in FIGS. 7 and 8) may be coupled to the rear surface of the refrigerating compartment door 32, and the left end of the wire cover 410 (in FIGS. 7 and 8) may be fitted to and coupled to the upper decoration 250.

[0127] Hereinafter, the flowing state of cold air in the refrigerator having the above configuration according to the present disclosure will be described.

[0128] First, cold air inside the refrigerating compartment may be supplied into the blocking casing 100 by the fan motor 300. That is, when the fan motor 300 is operated by power, the cold air of the inside of the refrigerating compartment may be introduced into the blocking casing 100 through the upper side of the blocking casing 100.

[0129] The cold air introduced into the blocking casing 100 by the fan motor 300 may be introduced thereinto first by passing through the vent hole 252 of the upper decoration 250, and the cold air blowing by passing through the fan motor 300 may pass consecutively through the installation hole 214 of the fixing frame 210 and the through hole 232 of the lower decoration 230, and may be introduced into the blocking casing 100.

[0130] The cold air introduced into the blocking casing 100 may cool food stored in the door basket 35.

[0131] Then, when the home bar door 80 is opened, the cold air inside the blocking casing 100 may escape to the outside of the refrigerator, and thus an air temperature inside the blocking casing 100 may increase.

[0132] Of course, when the home bar door 80 is opened, the fan motor 300 may be controlled not to be operated. That is, the fan motor 300 may be controlled to be operated only when the home bar door 80 is closed.

[0133] In addition, the fan motor 300 may detect the temperature of the inside of the blocking casing 100, and may be controlled to be operated only when the detected temperature reaches a preset temperature or more.

[0134] Accordingly, in the refrigerator of the present disclosure, even when the home bar door 80 of the refrigerator is opened, the cold air inside the refrigerating compartment, due to the blocking casing 100, may be prevented from being discharged to the outside through the home bar.

[0135] The technical scope of the present disclosure may not be limited to the embodiment illustrated above, and within the technical scope as described above, many other modifications based on the present disclosure will be possible for those skilled in the art.

[0136] For example, in the embodiment described above, the fastening hook 260 may be formed at the upper decoration 250, and the fastening hole 220 to which the fastening hook 260 is fitted and fastened may be formed in the fixing frame 210, but the reverse is also possible. That is, the fastening hook 260 may be provided at the fixing frame 210, and the fastening hole 220 may be formed in the upper decoration 250.
