    DETAILED DESCRIPTION



    [0031] Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.

    [0032] With reference to FIGS. 1 and 2, a refrigerator in accordance with one embodiment includes a main body 10 forming the exterior of the refrigerator and provided with a plurality of storage chambers 20 formed therein, and doors 25 and 27 rotatably installed on the main body 10 so as to open and close the storage chambers 20.

    [0033] The main body 10 includes an outer case 11 forming the exterior of the main body 10, an inner case 15 installed within the outer case 11 and forming the plurality of storage chambers 20, a foaming agent 17 filling a space between the outer case 11 and the inner case 15, and a machinery room (not shown) to receive a plurality of electronic and electrical components.

    [0034] The majority of the outer case 11 is made of metal in consideration of durability, and the inner case 15 is made of resin in consideration of a heat insulating function and convenience in manufacturing.

    [0035] The outer case 11 includes a main frame 12 having a U shape to form lower and both side surfaces of the main body 10, an upper frame 13 connected to the upper portion of the main frame 12 to form an upper surface of the main body 10, and a rear frame 14 connected to the rear portion of the main frame 12 to form a rear surface of the main body 10.

    [0036] The inside of the inner case 15 is divided into a first storage chamber 21 and a second storage chamber 22 by a vertical diaphragm 16 provided at the center of the inner case 15. Here, the first storage chamber 21 serves as a refrigerating chamber, and the second storage chamber 22 serves as a freezing chamber.

    [0037] The doors 25 and 27 include a first door 25 to open and close the first storage chamber 21, and a second door 27 to open and close the second storage chamber 22. The first door 25 and the second door 27 are rotatably connected to the main body 10 through hinge units 30 and 31 disposed on the upper and lower surfaces of the main body 10.

    [0038] The hinge units 30 disposed on the upper surface of the main body 10 are received in hinge receipt parts 18 depressed on the upper surface of the main body 10 so as not to be protruded outward from the upper surface of the main body 10. That is, the upper surfaces of the hinge units 30 are disposed to be coplanar with the upper surface of the main body 10, thereby improving the aesthetics of the exterior of the refrigerator.

    [0039] Further, the hinge units 31 disposed on the lower surface of the main body 10 rotatably support the lower surfaces of the doors 25 and 27 through hinge brackets mounted on the lower surface of the main body 10. This reduces the thickness of the lower end of the main body 10, thereby increasing a volume of the storage chambers 20.

    [0040] A plurality of door guards 29 to receive a small volume of food, is provided on the inner walls of the doors 25 and 27.

    [0041] A plurality of shelves 40 vertically separated from each other is provided in the upper portion of the storage chamber 21, and a sub-storage chamber 80, the temperature of which is controlled separately from the storage chamber 21, is provided in the lower portion of the storage chamber 21.

    [0042] With reference to FIGS. 3 and 4A, a plurality of support ribs 41, which is protruded such that both side ends of the shelf 40 are respectively supported by the support ribs 41, is provided on both side walls of the storage chamber 21, and a latch groove 42, which is depressed, is provided at the middle portion of the support rib 41.

    [0043] That is, the support rib 41 is divided into a front rib 41a and a rear rib 41b, separated from each other, by the latch groove 42. That is, the latch groove 42 is disposed between the front rib 41a and the rear rib 41b.

    [0044] The shelf 40 includes a tempered glass panel 43, both side ends of which are seated on and supported by the support ribs 41 such that food is placed on the tempered glass panel 43, and stopper members 44 to restrict forward and backward movement of the tempered glass panel 43 when the tempered glass panel 43 is seated on the support ribs 41.

    [0045] The stopper members 44 are disposed at positions of both sides of the lower surface of the tempered glass panel 43 corresponding to the latch grooves 42 provided on the support ribs 41.

    [0046] The length of the latch grooves 42 is greater than the width of the stopper members 44 so as to allow the shelf 40 to be easily seated on and separated from the support ribs 41, and corresponds to the length L (FIG. 6B) of inclination prevention ribs 47, which will be described later. This serves to prevent the inclination prevention ribs 47 from interfering with rear end of the shelf 40 when the shelf 40 is separated from the support rib 41.

    [0047] These stopper members 44 are directly fixed to the tempered glass panel 43 through an adhesive agent 45. Such a method does not require a separate processing operation of the tempered glass panel 43, thus forming the fine exterior of the tempered glass panel 43.

    [0048] This embodiment describes that the stopper members 44 are fixed to the tempered glass panel 43 through the adhesive agent 45. However, as shown in FIG. 4B, separate hook holes 43a may be formed through both sides of the tempered glass panel 43, and the stopper members 44 may be provided with hook parts 44a hooked to the hook hole 43a. This method facilitates assembly and disassembly of the stopper members 44, thus improving workability.

    [0049] Frames 48 and 49 surrounding the front and rear ends of the tempered glass panel 43 are provided with the shelf 40. The frames 48 and 49 include a front frame 48 surrounding the front end of the tempered glass panel 43 and a rear frame 49 surrounding the rear end of the tempered glass panel 43.

    [0050] Such frames 48 and 49 are made of resin, such as Acrylonitrile Butadiene Styrene (ABS). The outer surfaces of the frames 48 and 49 are coated with a film 46 made of metal, such as aluminum, as shown in FIG. 5. The film 46 may be formed on the frames 48 and 49 through insert molding when the frames 48 and 49 made of resin are molded.

    [0051] These frames 48 and 49 improve productivity due to reduction of material costs, compared with conventional decorative frames made of aluminum or stainless steel.

    [0052] Further, the frames 48 and 49 in accordance with this embodiment are not provided at both side ends of the tempered glass panel 43, thereby improving visibility and thus increasing the apparent volume of the storage chamber 21.

    [0053] With reference to FIGS. 3 and 6A, the inclination prevention ribs 47 to prevent the shelf 40 seated on the support ribs 41 from being inclined forward are provided at the rear portions of both side walls of the storage chamber 21.

    [0054] The inclination prevention ribs 47 are separated from the support ribs 41 so as to support the upper surface of the rear portion of the shelf 40 seated on the support ribs 41, and are protruded from the side walls of the inner case 15.

    [0055] The inclination prevention ribs 47 are provided above the rear ribs 41b, and the rear end of the shelf 40 is inserted into spaces between the rear ribs 41b and the inclination prevention ribs 47.

    [0056] In order to mount the shelf 40 in the storage chamber 21, when the stopper members 44 are inserted into the latch grooves 42 and then the shelf 40 is pushed into the storage chamber 21, the stopper members 44 are moved to rear end 42b of the latch grooves 42, and simultaneously, the rear end of the shelf 40 is inserted into the spaces between the rear ribs 41b and the inclination prevention ribs 47.

    [0057] In this case, even if food is placed on the shelf 40, the rear end of the shelf 40 is supported by the inclination prevention ribs 47 and thus forward inclination of the shelf 40 is prevented.

    [0058] On the other hand, in order to separate the shelf 40 from the storage chamber 21, when the shelf 40 is pulled forward, the stopper members 44 are moved to the front end 42a of the latch grooves 42, and simultaneously, the rear end of the shelf 40 is separated from the inclination prevention ribs 47, as shown in FIG. 6B. Thereafter, when the shelf 40 is lifted upward, the shelf 40 is separated from the support ribs 41.

    [0059] Through such a configuration, the shelf 40 does not require a separate support structure to prevent the shelf 40 from being inclined forward when food is placed on the shelf 40, and thus a mold for the shelf 40 has a simple structure, thereby reducing material costs of the shelf 40.

    [0060] With reference to FIG. 3, an evaporator 51 connected with a refrigeration cycle and forming a closed circuit together with the refrigeration cycle to generate cool air and a cool air duct assembly 50 to supply the cool air generated by the evaporator 51 to the storage chamber 21 are provided at the rear portion of the storage chamber 21.

    [0061] The cool air duct assembly 50 includes an insulation pad 52 provided with a channel 53 to supply the cool air generated by the evaporator 51 to the storage chamber 21 or to inhale cool air from the storage chamber 21, and a front cover 54 made of resin to cover the front portion of the insulation pad 52.

    [0062] An air blower fan 57 to forcibly blow cool air to the storage chamber 21 is provided in the channel 53. The air blower fan 57 is installed at a mount part 58 formed integrally with the insulation pad 52.

    [0063] The air blower fan 57 is a centrifugal fan integrated with a motor, and is installed at an upstream portion of the channel 53 of the insulation pad 52.

    [0064] The mount part 58 is a plate made of resin to fix the air blower fan 57, and is formed integrally with the insulation pad 52 through insert molding when the insulation pad 52 is molded.

    [0065] The insulation pad 52 is made of a foamed insulation material so as to reduce a heat loss of the cool air. For example, the insulation pad 52 may be made of polyethylene foam.

    [0066] Through such a configuration, assembly efficiency and productivity of the cool air duct assembly 50 are improved due to reduction of the number of parts of the cool air duct assembly 50.

    [0067] Cool air outlets 55 through which the cool air generated by the evaporator 51 is discharged to the storage chamber 21 are provided at both sides of the front cover 54.

    [0068] The cool air outlets 55 are configured such that the cool air discharged to the storage chamber 21 through the cool air outlets 55 may be discharged toward the upper portion of the storage chamber 21, as shown in FIG. 7A. For this purpose, a discharge channel 56 provided at the rear of the cool air outlet 55 is inclined downward.

    [0069] This configuration of the cool air outlets 55 to discharge the cool air toward the upper portion of the storage chamber 21 minimizes visible regions through which a user in front of the storage chamber 21 observes the inside of the cool air duct assembly 50, thereby improving the aesthetics of the cool air duct assembly 50.

    [0070] Further, the cool air discharged upward at a designated angle relative to the front surface of the storage chamber 21 improves circulation of the cool air in the storage chamber 21, thereby uniformly maintaining the inner temperature of the storage chamber 21.

    [0071] This embodiment describes that the discharge channels 56 are inclined downward so as to minimize the visible regions through which the user in front of the storage chamber 21 observes the inside of the cool air duct assembly 50, as shown in FIG. 7A. However, if discharge channels 56a are disposed horizontally, as shown in FIG. 7B, the front cover 54 surrounding the insulation pad 52 may be provided with flanges 54a which is bent so as to surround the front portions of the inner surfaces of the discharge channels 56a. This configuration also prevents lowering of the aesthetics of the cool air duct assembly 50 due to exposure of the insulation pad 52 when a user in front of the storage chamber 21 observes the inside of the cool air duct assembly 50 through the cool air outlet 55.

    [0072] With reference to FIGS. 3 and 8, an illumination unit 60 to illuminate the storage chamber 21 is provided at the upper region of the rear portion of the storage chamber 21.

    [0073] The illumination unit 60 includes an illumination plate 61 fixed to the rear wall of the inner case 15 of the storage chamber 21, a light source 62 supported by the illumination plate 61 to emit light so as to illuminate the inside of the storage chamber 21, and a transparent cover 65 to transmit the light emitted from the light source 62.

    [0074] The light source 62 includes light emitting diodes 63, and a circuit board 64 on which the light emitting diodes 63 are mounted.

    [0075] The light source 62 is adhered to one end of the transparent cover 65 so as to irradiate light to the inside of the transparent cover 65.

    [0076] The transparent cover 65 is made of transparent acryl-based resin so as to diffuse the light, emitted from the light source 62, toward the front portion of the storage chamber 21.

    [0077] Reflectors 66 to uniformly disperse the light emitted from the light source 62 throughout the transparent cover 65 are provided on the transparent cover 65.

    [0078] The reflectors 66 are formed in a UV pattern of fine protrusions printed on the rear surface of the transparent cover 65 through an ultraviolet curable printing method.

    [0079] Through this configuration, the illumination unit 60 has a simple structure as well as prevents glare caused by the light source 62 due to indirect illumination by the transparent cover 65.

    [0080] With reference to FIGS. 3 and 9, a defrosting heater 70 to remove frost formed on the evaporator 51 due to a temperature difference is provided below the evaporator 51.

    [0081] When power is supplied to the refrigerator, heat generated by a heating part of the defrosting heater 70 is applied to the evaporator 51, thereby removing frost formed on the surface of the evaporator 51.

    [0082] A heater cover 71 to shield the heat of the defrosting heater 70 is provided between the defrosting heater 70 and the inner case 15.

    [0083] The heater cover 71, as shown in FIG. 9, is separated from the inner case 15 by a designated distance by a separation member 73.

    [0084] The separation member 73 prevents heat generated by the defrosting heater from degrading and carbonizing peripheral structures (e.g. the inner case) around the defrosting heater 70 through the heater cover 71.

    [0085] With reference to FIG. 10, the sub-storage chamber 80, the temperature of which is controlled separately from the storage chamber 21 through the cool air duct assembly 50, is provided in the lower portion of the storage chamber 21.

    [0086] The sub-storage chamber 80 includes a housing 83 forming a storage space 81 and provided with an opening 82 formed through the front surface thereof, and a drawer container 84 to move forward and backward installed in the storage space 81 so as to open and close the opening 82. The drawer container 84 includes a receipt part 85 to receive food, and a cover part 86 disposed on the front surface of the receipt part 85 to open and close the opening 83.

    [0087] The sub-storage chamber 80 is provided in the refrigerating chamber so as to serve as a thawing chamber to thaw frozen food, or is provided in the freezing chamber so as to serve as a rapid cooling chamber to rapidly cool food.

    [0088] A gasket 87 to hermetically seal a gap between the drawer container 84 and the housing 83 and to insulate the sub-storage chamber 80 is provided at the edge of the opening 82 of the sub-storage chamber 80. This prevents lowering of the quality of the exterior of the sub-container 80 if the cover part 86 of the drawer container 84 is made of a transparent material.

    [0089] Through this configuration, the sub-storage container 80 forms the storage space 81 independently of the storage chamber 21, and the storage temperature of the storage space 81 of the sub-storage chamber 80 is independently controlled according to an amount of cool air supplied to the sub-storage chamber 80.

    [0090] FIG. 11 is a perspective view of a receipt box of the refrigerator in accordance with a preferred embodiment of the invention.

    [0091] With reference to FIG. 11, a receipt box 90 is slidably installed under a shelf 97 (with reference to FIG. 12A). Rail fixing members 96 to fix three-stage slide rails 95 are installed on both side walls of the storage chamber 21 adjacent to both side surfaces of the receipt box 90.

    [0092] One surface of each of the three-stage slide rails 95 is connected with one side surface of the receipt box 90, and the other surface of each of the three-stage slide rails 95 is connected with the rail fixing member 96.

    [0093] The upper portion of the receipt box 90 is opened so as to store food. If the receipt box 90 is inserted into the inside of the storage chamber 21, a part of the opened upper surface of the receipt box 90 is closed by the shelf 97, and the remaining part of the opened upper surface of the receipt box 90 is closed by a cover 100.

    [0094] The cover 100 is hinged to the shelf 97, and is rotated. A front end 101 of the cover 100 serves as a free terminal and a rear end 102 of the cover 100 is hinged to the shelf 97 and vertically rotated about a rotary shaft 104.

    [0095] Rolling friction parts 103 are provided on the lower surface of the cover 100, and contact the receipt box 90 to generate friction. The rolling friction parts 103 generate friction with the receipt box 90 when the receipt box 90 is inserted into or extended from the inside of the storage chamber 21.

    [0096] Various inclined planes are formed in the lengthwise direction on the upper surfaces of both side walls 94 of the receipt box 90 contacting the rolling friction parts 103. The inclined planes formed on the upper surface of one side wall 94 of the receipt box 90 include an upwardly inclined plane 91, a level plane 92, and a downwardly inclined plane 93.

    [0097] Thereby, when the receipt box 90 is extended from the inside of the storage chamber 21, as shown in FIG. 12A, the rolling friction parts 103 of the cover 100 move along the inclined planes, and thus the cover 100 is rotated upward about the rotary shaft 104.

    [0098] On the other hand, when the receipt box 90 is inserted into the inside of the storage chamber 21, as shown in FIG. 12B, the cover 100 closes the upper region of the front portion of the receipt box 90. Here, the cover 100 is rotated downward about the rotary shaft 104 by the rolling friction parts 103 moving from the level plane 92 to the upwardly inclined plane 91. Then, the front end 101 of the cover 100 collides with the receipt box 90, and thus may generate noise.

    [0099] In order to prevent such noise generation, buffering members 110 are provided between the cover 100 and the receipt box 90. The buffering members 110 are provided on the upper surfaces of the front portions of both side walls 94 of the receipt box 90. However, the buffering members 110 may be provided at positions where the cover 100 and the receipt box 90 contact each other.

    [0100] The buffering members 110 may be rubber pads or pads made of other elastic materials.

    [0101] Through this configuration, if the receipt box 90 is inserted into the inside of the storage chamber 21, although the cover 100 is rotated downward and collides with the receipt box 90, the buffering members 100 absorb impact applied by the cover 100, thereby reducing noise generation due to collision of the cover 100 with the receipt box 90.

    [0102] As is apparent from the above description, a refrigerator in accordance with the invention increases assembly efficiency of shelves and improves productivity due to reduction of material costs.

    [0103] Further, the refrigerator prevents degradation of peripheral structures caused by a heater.

    [0104] Further, the refrigerator improves assembly efficiency of a cool air duct.

    [0105] Moreover, the refrigerator improves the exterior of a drawer.

    [0106] Although a few embodiments have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the invention, the scope of which is defined by the claims.
