Description

refrigerator

[0001] The present invention relates to a refrigerator.

[0002] A refrigerator is a home appliance that supplies cold air generated by the circulation of refrigerant to a storage room, thereby keeping various types of storage objects fresh for a long period of time.

[0003] To more easily identify the food stored in the storage room, a lighting device may be installed in the storage room.

[0004] Lighting devices are placed on the walls at the back or left and right sides of the storage room so that the interior of the storage room can be illuminated when the door is opened.

[0005] However, in the case of lighting devices placed on the walls of storage rooms, users may be directly exposed to light, so if the illuminance is high, glare may occur to users.

[0006] Additionally, when lowering the brightness of lighting devices to reduce glare, there is a problem of not sufficiently illuminating the interior of the storage room.

[0007] In addition, when food is located adjacent to a place illuminated by a lighting device, there is a problem in that the food blocks the lighting device, so light is not evenly distributed throughout the entire storage space.

[0008] Meanwhile, shelves may be provided inside the storage room for efficient storage of food and convenience of use by the user.

[0009] For shelves, it may include plates to support the groceries.

[0010] The plates are formed to have a very large support area in the horizontal direction across the storage compartment, so that they can sufficiently support a large number of food items.

[0011] An object of the present invention is to provide a refrigerator including a shelf that can substantially function as a lighting device.

[0012] Another object of the present invention is to provide a refrigerator that can evenly and effectively illuminate the interior of a storage compartment regardless of the location of food.

[0013] Another object of the present invention is to provide a refrigerator that can eliminate the problem of glare to the user caused by a lighting device.

[0014] Another object of the present invention is to provide a refrigerator that is advantageous in commonizing parts that constitute a shelf.

[0015] Another object of the present invention is to provide a refrigerator capable of increasing the brightness of light diffused through a plate.

[0016] Another object of the present invention is to provide a refrigerator that can further enhance user convenience by further improving the brightness of light in the front of the storage room.

[0071] Hereinafter, a refrigerator according to some embodiments of the present invention will be described.

[0072] A refrigerator including a shelf according to one embodiment of the present invention will be described with reference to FIGS. 1 to 4.

[0073] A refrigerator (1) may have an exterior formed by a cabinet (10) including one or more storage rooms (16) inside which are storage spaces for products, and one or more doors (13) that can open and close the open front of the cabinet (10).

[0074] The cabinet (10) may include an outer case (12) and an inner case (11) coupled to the inside of the outer case (12).

[0075] The inner case (11) may include one or more storage compartments (16), and the storage compartments (16) may be a refrigerator or a freezer.

[0076] In Fig. 1, the inner case (11) is illustrated as including one storage room (16), but this is not limited to the inner case (11), and a plurality of storage rooms may be provided by partitioning the inner case (11).

[0077] The door (13) may be a revolving door that rotates via a pair of hinges (14) arranged at the top and bottom, but is not limited thereto.

[0078] If there are multiple storage rooms, there are also multiple doors so that each storage room can be opened and closed.

[0079] Meanwhile, one or more storage compartments (15) capable of storing and supporting food may be arranged in the door (13).

[0080] Additionally, one or more drawers (17) and shelves (30) for storing and supporting food may be arranged within the storage room (16).

[0081] For example, one or more drawer sections (17) may be arranged in the lower area of ​​the storage room (16).

[0082] The drawer section (17) can provide a drawer-type storage space that can be pulled out and in in the front and rear directions.

[0083] One or more shelves (30) can be arranged on the upper part of the drawer section (17).

[0084] In the case where a plurality of shelves (30) are provided, adjacent shelves (30) can be arranged in a vertical direction with a predetermined distance between them.

[0085] In addition, in Fig. 1, one example is shown in which one shelf (30) is placed at the same height, but it is not limited thereto.

[0086] For example, multiple shelves (30) may be arranged parallel to each other at the same height.

[0087] In this case, a plurality of shelves (30) arranged in a horizontal direction and a plurality of shelves (30) arranged in a vertical direction can be arranged in the storage room (16).

[0088] The shelf (30) may include a plate (100) having a large surface area to support food, a front frame (200) that finishes the front of the plate (100), a rear frame (300) that finishes the rear of the plate (100), and a pair of side frames (400) that finish both sides of the plate (100).

[0089] For example, at least a portion of the front end of the shelf (30) may be inserted and fixed within the front frame (200), and at least a portion of the rear end of the shelf (30) may be inserted and fixed within the rear frame (300).

[0090] And at least a portion of the side end of the shelf (30) is placed on the side frame (400), so that the lower surface can be supported by the side frame (400).

[0091] The side frame (400) may include a front shield (441) and a rear shield (442) that close the open sides of the front frame (200) and the rear frame (300), respectively.

[0092] A front fastening hole (441h) is formed in the front shield (441), so that the front frame (200) and the side frame (400) can be fastened by a separate fastening member such as a screw.

[0093] In addition, a rear fastening hole (442h) is formed in the rear shield (442), so that the rear frame (300) and the side frame (400) can be fastened by a separate fastening member such as a screw.

[0094] A mounting protrusion (430) may be formed at the rear end of the side frame (400).

[0095] For example, the mounting protrusion (430) may be formed in a hook shape, such as a shape that protrudes rearward from the rear end of the side frame (400) and then bends downward again.

[0096] The shelf (30) can be detachably mounted in the storage room (16).

[0097] In addition, the shelf (30) can be freely adjusted in height by removing and installing it.

[0098] The shelf (30) can be configured so that the rear end portion is mounted on the rear wall of the storage room (16) in a cantilever manner.

[0099] At the rear of the storage room (16), a shelf mounting member (20) to which a shelf (30) can be mounted and fixed can be placed.

[0100] For example, the shelf mounting member (20) can be mounted on the rear side (11a) of the inner case (11).

[0101] The shelf mounting member (20) can be arranged to extend along the rear wall in the vertical direction of the storage room (16).

[0102] For example, the shelf mounting members (20) are provided in pairs, and the pair of shelf mounting members (20) can be fixed and arranged on the rear wall while being spaced apart from each other on the left and right.

[0103] Each shelf mounting member (20) may be formed with one or more mounting holes (21) into which a mounting protrusion (430) formed at the rear end of the shelf (30) can be inserted and fastened.

[0104] The mounting hole (21) can be formed in a form in which the front is open so that the mounting protrusion (430) can be inserted.

[0105] The mounting holes (21) are provided in multiple numbers and can be arranged so as to be spaced apart in the vertical direction along the direction in which the shelf mounting member (20) extends.

[0106] A pair of shelf mounting members (20) can be placed at positions corresponding to the mounting protrusions (430) formed at the rear end of each shelf (30).

[0107] For example, a pair of shelf mounting members (20) may be arranged spaced apart left and right by the same spacing as a pair of mounting protrusions (430).

[0108] Therefore, after removing the mounted shelf (30), the user can freely adjust the mounting height of the shelf (30) by fastening the mounting protrusion (430) of the shelf (30) to the mounting hole (21) of the desired height.

[0109] In addition, when a plurality of shelves (30) are arranged in parallel at the same height, a plurality of shelf mounting members (20) can be arranged in parallel in the left-right direction correspondingly.

[0110] For example, a pair of shelf mounting members (20) may be arranged on each of the left and right sides of the rear of the storage room (16), and an additional shelf mounting member (20) may be arranged in the central area of ​​the rear of the storage room (16).

[0111] In this case, the shelf mounting member (20) placed in the central area may also be placed in multiple numbers, and when the shelf mounting member (20) placed in the central area is placed as one, a pair of shelves (30) placed in parallel at the same height may share the shelf mounting member (20) placed in the central area.

[0112] Meanwhile, one or more lighting devices, which will be described later, may be placed on the shelf (30).

[0113] A power receiver (800) that supplies power to the lighting device can be placed on the side frame (400).

[0114] The power receiver (800) can be placed on only one side frame (400) among a pair of side frames (400).

[0115] In the case where multiple shelves (30) are arranged at the same height, each shelf (30) may have a power receiver (800) placed on an opposite side frame (400).

[0116] That is, a power receiver (800) can be placed on the side frame (400) of each shelf (30) adjacent to the side (11b) of the storage room (16).

[0117] A protrusion (420) protruding from the outer surface of the side frame (400) may be formed on one side of the side frame (400), and a power receiver (800) may be placed on the inner side of the protrusion (420).

[0118] One or more power supply units (900) may be placed inside the storage room (16) to supply power to a power receiver unit (800) placed on a shelf (30).

[0119] The power supply unit (900) can wirelessly transmit power to the power reception unit (800), and the power reception unit (800) can wirelessly receive power from the power supply unit (900).

[0120] For example, one or more power supplies (900) may be placed on a side (11b) of the inner case (11).

[0121] The power supply unit (900) can be placed only on one side of the storage room (16) adjacent to the direction in which the power receiver unit (800) of the shelf (30) is placed.

[0122] However, in the case where multiple shelves (30) are arranged at the same height, power supply units (900) may be arranged on both sides of the storage room (16).

[0123] That is, the power supply unit (900) provided on the left wall of the storage room (16) is coupled with the power receiver unit (800) of the shelf (30) on the left to supply power to the shelf (30) on the left, and the power supply unit (900) provided on the right wall of the storage room (16) is coupled with the power receiver unit (800) of the shelf (30) on the right to supply power to the shelf (30) on the right.

[0124] A plurality of power supply units (900) are provided, and the plurality of power supply units (900) can be arranged in the vertical direction along the direction in which the shelf mounting member (20) extends.

[0125] That is, multiple power supply units (900) can be arranged in the vertical direction corresponding to the height at which the shelf (30) can be mounted.

[0126] Each power supply unit (900) can be arranged in parallel with the mounting hole (21) in the left and right directions, corresponding to the mounting hole (21) of each shelf mounting member (20).

[0127] Accordingly, even when a user removes the shelf (30) to adjust the height of the shelf (30) and then attaches the shelf (30) to a mounting hole (21) located at a different height, the shelf (30) can be supplied with power by the power supply unit (900) arranged parallel to the mounting hole (21) to which it is attached.

[0128] Accordingly, while increasing the user's convenience by allowing the height of the shelf (30) to be freely adjusted, power can be stably supplied to the shelf (30) regardless of the height of the shelf (30).

[0129] The method by which the power supply unit (900) wirelessly transmits and receives power to the power receiver unit (800) is not limited, but for example, one of the inductive power method, the electromagnetic wave method, and the ultrasonic method may be used.

[0130] The following is a description of each power wireless transmission and reception method.

[0131] For example, the inductive power method may be a method in which a primary coil that receives energy from an external power source and forms a magnetic field is formed in the power supply unit (900), and a secondary coil that generates an induced electromotive force due to the magnetic field is formed in the power receiving unit (800).

[0132] The electromagnetic wave method may be a method in which a power supply unit (900) includes a magnetron that receives energy from an external power source and radiates electromagnetic waves, and a power receiving unit (800) includes an electromagnetic wave receiver that converts the received electromagnetic waves into electrical energy.

[0133] The ultrasonic method may be a method in which the power supply unit (900) includes an ultrasonic emitter that receives energy from an external power source and emits ultrasonic waves, and the power receiving unit (800) includes an ultrasonic receiver that converts the received ultrasonic waves into electrical energy.

[0134] In this specification, a power supply unit (900) and a power receiver unit (800) to which an inductive power method is applied are described as an example.

[0135] The power supply unit (900) may be equipped with a primary coil that forms a magnetic field, and the power receiving unit (800) may be equipped with a secondary coil that generates an induced electromotive force.

[0136] Inside the power supply unit (900), a spiral primary coil may be provided in an oval shape extending vertically, and a plurality of spiral primary coils may be provided and arranged vertically.

[0137] Additionally, a spiral primary coil may be provided in an oval shape extending vertically inside the power supply unit (900), and a plurality of spiral primary coils may be provided and arranged vertically.

[0138] In this way, the power receiver (800), which receives power wirelessly from the power supply (900), is connected to the lighting device via a wire, so that the power transmitted to the power receiver (800) can be transmitted to the lighting device.

[0139] The wire connecting the power receiver (800) and the lighting device is placed within the side frame (400) and can be connected to the lighting device through the side openings of the front frame (200) and the rear frame (300).

[0140] Hereinafter, a shelf (30) including a lighting device according to one embodiment of the present invention will be described in detail with reference to FIGS. 4 to 7.

[0141] The shelf (30) may include a plate (100) that forms a surface on which food is placed.

[0142] The plate (100) can be formed into a rectangular plate shape overall.

[0143] The plate (100) can diffuse light incident from a lighting device to be described later to the upper and rear surfaces of the plate (100) and emit light to the outside.

[0144] Therefore, the plate (100) can serve as a light guide member that guides light by diffusing or scattering the light.

[0145] For this purpose, the plate (100) may be made of a transparent material that allows light transmission.

[0146] For example, the plate (100) can use a transparent material, and the transparent material is a transparent material including a translucent material, such as glass and a transparent injection-molded material, and can be formed of a polymer material such as PMMA, but is not limited thereto.

[0147] For example, the plate (100) may be formed of a glass material.

[0148] Since the plate (100) is formed of glass material, it can secure strength that can stably support food and can also have high scratch resistance.

[0149] The plate (100) can be surface treated on the outer surface to effectively diffuse light, or a light diffusion pattern can be formed.

[0150] For example, by performing surface treatment such as etching on the upper or lower surface of the plate (100), diffusion through diffuse reflection of light can be effectively achieved on the upper or lower surface of the plate (100).

[0151] Additionally, an optical pattern having a predetermined pattern can be additionally formed on the upper or lower surface of the plate (100).

[0152] For example, the optical pattern may be, but is not limited to, a prism shape or a hemispherical shape that protrudes outward, and may also be formed in a shape that is sunken inward.

[0153] Additionally, the optical patterns can be provided in multiple forms.

[0154] For example, each optical pattern may be formed to extend in the left-right direction, and a plurality of optical patterns may be arranged to be spaced apart from each other by a predetermined distance in the front-back direction of the plate (100).

[0155] As the surface is treated or an optical pattern is formed on the upper or lower surface of the plate (100) in this way, light can be diffused more evenly through the upper and lower surfaces of the plate (100).

[0156] The front frame (200) placed on the front of the plate (100) can be formed with a length corresponding to the left and right width of the plate (100).

[0157] The front end of the plate (100) can be inserted and secured into the inside of the front frame (200).

[0158] For example, the front frame (200) may include a front portion (212) extending vertically to finish the front of the plate (100), an upper surface portion (211) extending to be bent rearward from the top of the front portion (212), and a lower surface portion (213) extending to be bent rearward from the bottom of the front portion (212).

[0159] The upper surface (211) can be extended in a horizontal direction, and the lower surface (213) can be extended to have a downwardly descending slope.

[0160] A first extension portion (217) can be formed at a predetermined distance from the front portion (212) and the rear portion, and the first extension portion (217) can extend in the vertical direction to connect the upper surface portion (211) and the lower surface portion (213).

[0161] A hole-shaped front fastening portion (201) can be formed in the space between the front portion (212) formed in this manner and the first extension portion (217).

[0162] The front fastening part (201) is positioned to correspond to the front fastening hole (441h) formed in the front shield part (441) of the side frame (400), so that the front frame (200) and the side frame (400) can be fastened by a separate fastening member such as a screw.

[0163] A step portion (214) can be formed at a predetermined distance from the first extension portion (217) and rearward.

[0164] The step portion (214) may be formed to extend upward from the lower surface portion (213), but be spaced apart from the upper surface portion (211) by a predetermined distance.

[0165] Accordingly, a first opening (231) opened toward the rear, in which a plate (100) is placed, can be formed between the upper surface (211) and the step portion (214).

[0166] A first receiving portion (221) having a hollow shape in the left-right direction can be formed by the upper portion (211), the first extension portion (217), the lower portion (213), and the step portion (214).

[0167] The first receiving portion (221) can be closed in the up-down and front-back directions, except for the first opening (231), and can be opened in the left-right direction.

[0168] The lower surface (213) forming the first receiving portion (221) can be formed to have a horizontal surface.

[0169] Accordingly, the lower portion (213) extending rearward from the front portion (212) can be formed in a form in which the vertical width increases as it goes rearward in the area corresponding to the first receiving portion (221).

[0170] On the lower surface of the upper surface (211) corresponding to the first receiving portion (221) and the upper surface of the lower surface (213), protrusions (219) protruding in the downward direction and the upward direction, respectively, can be formed.

[0171] The protrusion (219) can guide the first lighting device (500) to be described later so that it can be easily inserted and fixed into the first receiving portion (221).

[0172] An extended mounting portion (215) can be formed so as to be bent rearward from the top of the step portion (214).

[0173] A first opening (231) is formed between the mounting portion (215) and the upper surface (211), and the front end of the plate (100) can be inserted between the mounting portion (215) and the upper surface (211).

[0174] Therefore, the anchoring portion (215) can support the lower surface of the front end of the plate (100).

[0175] The fixing portion (215) is formed to extend further rearward than the upper surface (211), so as to stably support the lower surface of the front end of the plate (100).

[0176] A second extension portion (218) can be formed at a predetermined distance from the step portion (214) and rearward.

[0177] The second extension portion (218) can be extended in the vertical direction to connect the mounting portion (215) and the lower portion (213).

[0178] In this case, the end of the lower portion (213) may coincide with the lower end of the second extension portion (218).

[0179] A rear portion (216) can be formed by being spaced a predetermined distance from the second extension portion (218) to the rear.

[0180] The rear portion (216) can be formed to extend downward from the lower surface of the mounting portion (215).

[0181] The end of the rear portion (216) may coincide with the end of the mounting portion (215).

[0182] The rear portion (216) can substantially form the rear portion of the front frame (200).

[0183] The rear portion (216) may be extended in a downward direction, but may be extended to have a shorter length than the second extension portion (218).

[0184] A second opening (232) opened downward may be formed between the rear portion (216) and the second extension portion (218).

[0185] A second receiving portion (222) having a hollow shape in the left-right direction can be formed by the second extension portion (218), the mounting portion (215), and the rear portion (216).

[0186] The second receiving portion (222) can be closed in the upper direction and the front-back direction except for the second opening (232), and can be opened in the left-right direction.

[0187] A protrusion (219) protruding inwardly may be formed on the inner surface of the second extension (218) corresponding to the second receiving portion (222) and the inner surface of the rear portion (216), respectively.

[0188] The protrusion (219) can guide the second lighting device (600) to be described later so that it can be easily inserted and fixed into the second receiving portion (222).

[0189] The front frame (200) formed in this manner may include a first receiving portion (221) in which a first lighting device (500) is received and a second receiving portion (222) in which a second lighting device (600) is received.

[0190] The first receiving portion (221) is located in front of the plate (100) and can be arranged to overlap the plate (100) in the front-back direction.

[0191] The second receiving portion (222) is located below the plate (100) and can be arranged to overlap the plate (100) in the vertical direction.

[0192] The second receiving portion (222) is positioned at the rear of the first receiving portion (221), and is arranged so as not to overlap each other in the vertical direction, and may be arranged so that some areas overlap each other in the front-back direction.

[0193] The front frame (200) is formed to extend in one direction so that both sides are open, and the first receiving portion (221) can also be formed to extend in one direction so that both sides are open.

[0194] The first lighting device (500) can be inserted in a sliding manner through one side of the opened first receiving portion (221).

[0195] Accordingly, the first lighting device (500) can also be formed to extend in one direction with a length corresponding to the left and right width of the front frame (200).

[0196] The first lighting device (500) may include a first light-emitting member (510) and a first cover member (520).

[0197] The first light-emitting member (510) may include a substrate and one or more light sources arranged on the substrate.

[0198] For example, the light source may be configured to emit light of various colors, but is not limited thereto, and may emit light of a single color.

[0199] For example, the light source may be, but is not limited to, an RGB LED (Red Green Blue light emitting diode) or a Mini LED.

[0200] In this case, multiple light sources can be arranged spaced apart from each other in one direction on the substrate.

[0201] In addition, the light source may be provided in the form of a surface light source rather than a point light source, and may be formed to extend in one direction along the substrate.

[0202] The first cover member (520) can protect the first light-emitting member (510) from external impact.

[0203] The shape of the first cover member (520) is not particularly limited, and may be a bar shape that closes the front of the first light-emitting member (510), or a storage shape that wraps the first light-emitting member (510) to accommodate the first light-emitting member (510).

[0204] For example, referring to FIG. 6, the first cover member (520) can be formed to have a storage shape that surrounds the first light-emitting member (510).

[0205] In this case, the first cover member (520) can be formed to a size that can be accommodated in the first receiving portion (221).

[0206] On both sides of the first cover member (520), a protruding fastening portion (521) recessed inwardly may be formed to correspond to the protruding portion (219) formed in the first receiving portion (221) of the front frame (200).

[0207] Accordingly, the protruding fastening portion (521) of the first cover member (520) can be inserted along the protruding portion (219) of the first receiving portion (221), so that the first lighting device (500) can be fixed to the first receiving portion (221).

[0208] The first light-emitting member (510) can be arranged so that the light source emitting light faces the first opening (231).

[0209] And the first cover member (520) can be formed of a transparent material so that light from the light source can pass through.

[0210] The first lighting device (500) arranged in this manner can emit light toward the front of the plate (100), thereby allowing light to enter the interior of the plate (100), thereby allowing light to be emitted to the upper and lower surfaces of the plate (100).

[0211] In this case, the first light-emitting member (510) is positioned so that at least a portion of the front surface of the plate (100) overlaps with the front surface of the plate (100), so that light emitted from the first light-emitting member (510) can be incident on the front surface of the plate (100) with as little light loss as possible.

[0212] Therefore, the first light-emitting member (510), the first opening (231), and the front surface of the plate (100) can be arranged to overlap each other in the front-back direction.

[0213] The second receiving portion (222) can also be formed to extend in one direction so that both sides are open.

[0214] The second lighting device (600) can be inserted in a sliding manner through one side of the opened second receiving portion (222).

[0215] Accordingly, the second lighting device (600) can also be formed to extend in one direction with a length corresponding to the left and right width of the front frame (200).

[0216] The second lighting device (600) may include a second light-emitting member (610) and a second cover member (620).

[0217] The second light-emitting member (610) may include a substrate and one or more light sources arranged on the substrate.

[0218] The second light emitting member (610) can use the same light source as the first light emitting member (510).

[0219] The second cover member (620) can protect the second light-emitting member (610) from external impact.

[0220] The shape of the second cover member (620) is not particularly limited, and may be a bar shape that closes the front of the second light-emitting member (610), or a storage shape that wraps the second light-emitting member (610) to accommodate the second light-emitting member (610).

[0221] For example, referring to FIG. 6, the second cover member (620) can be formed to have a storage shape that surrounds the second light-emitting member (610).

[0222] In this case, the second cover member (620) can be formed to a size that can be accommodated in the second receiving portion (222).

[0223] On both sides of the second cover member (620), a protruding fastening portion (621) that is sunken inward may be formed to correspond to the protruding portion (219) formed in the second receiving portion (222) of the front frame (200).

[0224] Accordingly, the protruding fastening portion (621) of the second cover member (620) can be inserted along the protruding portion (219) of the second receiving portion (222), so that the second lighting device (600) can be fixed to the second receiving portion (222).

[0225] The second light-emitting member (610) can be arranged so that the light source emitting light faces the second opening (232).

[0226] And the second cover member (620) can be formed of a transparent material so that light from the light source can pass through.

[0227] The second lighting device (600) arranged in this manner can irradiate light in the opposite direction to where the plate (100) is arranged, rather than toward the plate (100).

[0228] That is, the second lighting device (600) can emit light downward from the plate (100).

[0229] Accordingly, the front frame (200) can accommodate both the first lighting device (500) and the second lighting device (600) that irradiate light in different directions.

[0230] That is, the first lighting device (500) irradiates light toward the front of the plate (100) so that light is emitted through the plate (100), thereby enabling a large-area surface light source to be implemented through the plate (100).

[0231] In addition, the second lighting device (600) can illuminate the front of the storage room (16) more brightly by irradiating light toward the lower direction of the plate (100), thereby increasing user convenience.

[0232] In addition, since the light emission direction of the first lighting device (500) and the second lighting device (600) is not directly exposed to the user, the glare phenomenon that may occur to the user can be reduced.

[0233] In addition, the first lighting device (500) facing the plate (100) of the shelf (30) and the second lighting device (600) irradiating light in the lower direction of the shelf (30) can be placed together on the front frame (200), thereby increasing the convenience of assembly and the usability of space.

[0234] Meanwhile, the rear frame (300) placed on the rear of the plate (100) can be formed with a length corresponding to the left and right width of the plate (100).

[0235] The rear end of the plate (100) can be inserted and secured into the inside of the rear frame (300).

[0236] For example, the rear frame (300) may include a rear portion (316) extending vertically to finish the rear surface of the plate (100), an upper portion (311) extending forwardly from the upper end of the rear portion (316), and a lower portion (313) extending forwardly from the lower end of the rear portion (316).

[0237] The upper surface (311) can extend horizontally, and the lower surface (313) can be formed to include surfaces of various shapes, such as a downwardly descending slope, a horizontal surface, and an upwardly rising slope.

[0238] A third extension portion (317) may be formed at a predetermined distance from the rear portion (316) and forward, and the third extension portion (317) may extend in the vertical direction to connect the upper surface portion (311) and the lower surface portion (313).

[0239] A hole-shaped rear fastening portion (301) can be formed in the space between the rear portion (316) and the third extension portion (317) formed in this manner.

[0240] The rear fastening part (301) is positioned to correspond to the rear fastening hole (442h) formed in the rear shield part (442) of the side frame (400), so that the rear frame (300) and the side frame (400) can be fastened by a separate fastening member such as a screw.

[0241] A step portion (314) can be formed at a predetermined distance forward from the third extension portion (317).

[0242] The step portion (314) may be formed to extend upward from the lower surface portion (313), but be spaced apart from the upper surface portion (311) by a predetermined distance.

[0243] Accordingly, a third opening (431) open forwardly and having a plate (100) disposed therein can be formed between the upper surface (311) and the step portion (314).

[0244] A third receiving portion (321) having a hollow shape in the left-right direction can be formed by the upper portion (211), the third extension portion (317), the lower portion (213), and the step portion (214).

[0245] The third receiving portion (321) can be closed in the up-down and front-back directions, except for the third opening (431), and can be opened in the left-right direction.

[0246] The lower surface (313) forming the third receiving portion (321) can be formed to have a horizontal surface.

[0247] On the lower surface of the upper surface (311) corresponding to the third receiving portion (321) and the upper surface of the lower surface (313), protrusions (319) protruding in the downward direction and the upward direction, respectively, can be formed.

[0248] The protrusion (319) can guide the third lighting device (700) to be described later so that it can be easily inserted and fixed into the third receiving portion (321).

[0249] An extended mounting portion (315) can be formed so as to be bent forward from the top of the step portion (314).

[0250] A third opening (431) is formed between the mounting portion (315) and the upper surface (311), and the rear end of the plate (100) can be inserted between the mounting portion (315) and the upper surface (311).

[0251] Therefore, the anchoring portion (315) can support the lower surface of the rear end of the plate (100).

[0252] In this case, the end of the mounting portion (315) may coincide with the end of the lower portion (313).

[0253] The third receiving portion (321) is located at the rear of the plate (100) and can be arranged to overlap the plate (100) in the front-back direction.

[0254] The rear frame (300) is formed to extend in one direction so that both sides are open, and the third receiving portion (321) can also be formed to extend in one direction so that both sides are open.

[0255] The third lighting device (700) can be inserted in a sliding manner through one side of the opened third receiving portion (321).

[0256] Accordingly, the third lighting device (700) can also be formed to extend in one direction with a length corresponding to the left and right width of the rear frame (300).

[0257] The third lighting device (700) may include a third light-emitting member (710) and a third cover member (720).

[0258] The third light-emitting member (710) may include a substrate and one or more light sources arranged on the substrate.

[0259] The third light-emitting member (710) can use the same light source as the third light-emitting member (710).

[0260] The third cover member (720) can protect the third light-emitting member (710) from external impact.

[0261] The shape of the third cover member (720) is not particularly limited, and may be a bar shape that closes the front of the third light-emitting member (710), or a storage shape that wraps the third light-emitting member (710) to accommodate the third light-emitting member (710).

[0262] For example, referring to FIG. 7, the third cover member (720) can be formed to have a storage shape that surrounds the third light-emitting member (710).

[0263] In this case, the third cover member (720) can be formed to a size that can be accommodated in the third receiving portion (321).

[0264] On both sides of the third cover member (720), a protruding fastening portion (721) that is sunken inward may be formed to correspond to the protruding portion (319) formed in the third receiving portion (321) of the rear frame (300).

[0265] Accordingly, the protruding fastening portion (721) of the third cover member (720) can be inserted along the protruding portion (319) of the third receiving portion (321), so that the third lighting device (700) can be fixed to the third receiving portion (321).

[0266] The third light-emitting member (710) can be arranged so that the light source emitting light faces the third opening (431).

[0267] And the third cover member (720) can be formed of a transparent material so that light from the light source can pass through.

[0268] The third lighting device (700) arranged in this manner can emit light toward the rear of the plate (100), thereby allowing light to enter the interior of the plate (100), thereby allowing light to be emitted to the upper and lower surfaces of the plate (100).

[0269] In this case, the third light-emitting member (710) is positioned so that at least a portion of the front surface of the plate (100) overlaps with the front surface of the plate (100), so that light emitted from the third light-emitting member (710) can be incident on the front surface of the plate (100) with as little light loss as possible.

[0270] Accordingly, the third light-emitting member (710), the third opening (431), and the rear surface of the plate (100) can be arranged to overlap each other in the front-back direction.

[0271] As described above, in the refrigerator (1) according to the present invention, since a lighting device that irradiates light with a plate (100) is placed on at least one of the front frame (200) and the rear frame (300), light from the lighting device can be diffused through the plate.

[0272] In this way, the plate (100) diffuses the light of the lighting device, so that the shelf (30) itself can actually function as a lighting device.

[0273] In addition, since the plate (100) having a large support area can diffuse the light of the lighting device, the interior of the storage room can be evenly and effectively illuminated regardless of the location of the food items even when a large number of food items are stored in the storage room.

[0274] In addition, since the light is diffused to the upper and lower surfaces of the plate (100), the user may not be directly exposed to the light, thereby eliminating the problem of glare to the user.

[0275] In addition, since a lighting device can be placed on the front frame (200) and the rear frame (300) that close the plate (100) to irradiate light onto the plate (100), there is an advantage in that existing components that make up the shelf (30) can be used without the need to add additional components or space for placing the lighting device, thereby facilitating the commonization of components.

[0276] In addition, since the lighting device can be illuminated from both the front and back of the plate (100), the brightness of the light diffused through the plate (100) can be effectively increased.

[0277] The front frame (200) and the rear frame (300) can be formed of an opaque material so that light does not pass through.

[0278] Accordingly, by allowing the light of the lighting device accommodated in the receptacles of the front frame (200) and the rear frame (300) to be emitted to the outside only through the openings, the occurrence of a light leak phenomenon in which light is emitted to an unintended area can be prevented.

[0279] As described above, the front frame (200) and the rear frame (300) are each open to allow a lighting device to be inserted, and a pair of side frames (400) can close both sides of the plate (100).

[0280] The side frame (400) may include a side frame body (410) extended with a front-rear length corresponding to the front-rear width of the side of the plate (100).

[0281] The side frame body (410) can be formed so that the vertical height increases from the front to the rear.

[0282] As the vertical height of the rear side of the side frame body (410) increases in this way, the load of the shelf (30) concentrated on the rear side of the side frame body (410) where the mounting protrusion (430) is formed can be stably supported, thereby preventing the occurrence of damage.

[0283] The lighting devices described above can be turned on when the door (13) is opened or by a specific operation of the user to illuminate the storage room (16).

[0284] Hereinafter, various embodiments of the first lighting device (500) and the second lighting device (600) accommodated in the front frame (200) will be described with reference to FIGS. 8 to 10.

[0285] Any content that overlaps with what has been explained previously will be omitted, and the explanation will focus on the differences.

[0286] Referring to FIG. 8, the front frame (200) may include a first receiving portion (221) in which a first lighting device (500) is received and a second receiving portion (222) in which a second lighting device (600) is received.

[0287] The first lighting device (500) may include a first light-emitting member (510) and a first back cover member (530) disposed on the back surface of the first light-emitting member (510).

[0288] The first back cover member (530) and the first light-emitting member (510) may be arranged on the rear side of the front part (212) so as to face the front side of the plate (100), i.e., the first opening (231).

[0289] Additionally, the first lighting device (500) may further include a first cover member (520).

[0290] In this case, the first cover member (520) can be positioned so as not to cover the front of the first light-emitting member (510).

[0291] For example, the first cover member (520) is placed on the lower surface of the upper surface (211) and can be placed between the first light-emitting member (510) and the plate (100).

[0292] The first light-emitting member (510) can be fixed to one side of the first cover member (520) and can be fastened in a direction perpendicular to the first cover member (520).

[0293] In this way, since the first cover member (520) is positioned so as not to block the space between the first light-emitting member (510) and the plate (100), light emitted from the first light-emitting member (510) can be prevented from being lost in the first cover member (520).

[0294] Referring to FIG. 9, the front frame (200) may include a first receiving portion (221) in which a first lighting device (500) is received and a second receiving portion (222) in which a second lighting device (600) is received.

[0295] The first lighting device (500) may include a first light-emitting member (510) and a first back cover member (530) disposed on the back surface of the first light-emitting member (510).

[0296] The first back cover member (530) and the first light-emitting member (510) may be arranged on the upper surface of the lower surface (213) and may be arranged to face the lower surface of the upper surface (211).

[0297] Therefore, the first light-emitting member (510) may not be placed directly toward the front of the plate (100).

[0298] A first reflector (540) that reflects the direction of light emitted from the first lighting device (500) toward the front of the plate (100) may be further placed within the first receiving portion (221).

[0299] The first reflector (540) may be positioned above the first lighting device (500).

[0300] For example, the first reflector (540) can be formed at the corner portion between the upper surface (211) and the front surface (212).

[0301] The first lighting device (500) emits light toward the first reflector (540), and the light reflected by the first reflector (540) can be reflected toward the front surface of the plate (100).

[0302] The first reflector (540) may be formed to have a sloped surface, but is not limited thereto, and may be formed to have a curved surface, and may be formed to have a pattern that can focus light in a desired direction and position with minimal loss.

[0303] In addition, the first reflector (540) may be provided as a separate structure from the front frame (200), but is not limited thereto, and may be formed as an integral part with the front frame (200).

[0304] Additionally, the first reflector (540) may be implemented in the form of a reflective sheet or reflective coating rather than in the form of a structure.

[0305] In this way, the light emitted from the first lighting device (500) is not directly emitted to the plate (100), but by using the first reflector (540), the light emitted from the first lighting device (500) can be indirectly emitted to the plate (100).

[0306] By using the first reflector (540) in this way, the light emitted from the first lighting device (500) can be reduced from being lost by being diverged in a direction other than the front surface of the plate (100), and can be focused so that it can be incident on the front surface of the plate (100) with as little loss as possible.

[0307] Referring to FIG. 10, the second lighting device (600) may include a second light-emitting member (610) and a second back cover member (630) disposed on the back surface of the second light-emitting member (610).

[0308] The second back cover member (630) and the second light-emitting member (610) may be arranged on the rear side of the step portion (214) and may be arranged to face the rear side (216).

[0309] Therefore, the second light-emitting member (610) may not be positioned to face the second opening (232) directly.

[0310] A second reflector (640) may be further placed within the second receiving portion (222) to reflect the direction of light emitted from the second lighting device (600) downward toward the second opening (232).

[0311] The second reflector (640) may be positioned behind the second lighting device (600).

[0312] For example, the second reflector (640) may be formed at the corner portion between the upper surface (211) and the rear surface (216).

[0313] The second lighting device (600) emits light toward the second reflector (640), and the light reflected by the second reflector (640) can be reflected downward where the second opening (232) is located.

[0314] In this way, the light emitted from the first lighting device (500) is not directly emitted to the second opening (232), but by using the second reflector (640), the light emitted from the second lighting device (600) can be indirectly emitted to the second opening (232).

[0315] By using the second reflector (640) in this way, the light emitted from the second lighting device (600) can be reduced from being lost by being emitted in a direction other than the second opening (232), and can be concentrated so that it can be emitted with maximum loss in the direction of the second opening (232).

[0316] A second cover member (620) may be placed in the second opening (232) to protect the second light-emitting member (610).

[0317] Referring to FIG. 11, the rear frame (300) may include a third receiving portion (321) in which a third lighting device (700) is received.

[0318] The third lighting device (700) may include a third light-emitting member (710) and a third back cover member (730) disposed on the back surface of the third light-emitting member (710).

[0319] The third back cover member (730) and the third light-emitting member (710) may be arranged on the front side of the rear portion (316) so as to face the rear side of the plate (100), i.e., the third opening (431).

[0320] In this way, since the light emitted from the third light-emitting member (710) can be directly irradiated to the plate (100), the light emitted from the third light-emitting member (710) can be prevented from being lost by other structures such as a cover member.

[0321] Referring to FIG. 12, the rear frame (300) may include a third receiving portion (321) in which a third lighting device (700) is received.

[0322] The third lighting device (700) may include a third light-emitting member (710) and a third back cover member (730) disposed on the back surface of the third light-emitting member (710).

[0323] The third back cover member (730) and the third light-emitting member (710) may be arranged on the upper surface of the lower surface (313) and may be arranged to face the lower surface of the upper surface (311).

[0324] Therefore, the third light-emitting member (710) may not be placed directly toward the rear of the plate (100).

[0325] A third reflector (740) that reflects the direction of light emitted from the third lighting device (700) toward the rear of the plate (100) may be further placed within the third receiving portion (321).

[0326] The third reflector (740) may be positioned above the third lighting device (700).

[0327] For example, the third reflector (740) may be formed at the corner portion between the upper surface (311) and the rear surface (316).

[0328] The third lighting device (700) emits light toward the third reflector (740), and the light reflected by the third reflector (740) can be reflected toward the back of the plate (100).

[0329] In this way, the light emitted from the third lighting device (700) is not directly emitted to the plate (100), but by using the third reflector (740), the light emitted from the third lighting device (700) can be indirectly emitted to the plate (100).

[0330] By using the third reflector (740) in this way, the light emitted from the third lighting device (700) can be reduced from being lost by being diverged in a direction other than the rear surface of the plate (100), and can be focused so that it can be incident on the rear surface of the plate (100) with as little loss as possible.

[0331] Meanwhile, referring further to FIG. 13, the side frame (400) may include a side frame body (410) and a wall (481) formed in the rear region of the side frame body (410) to form a mounting portion (482) in which the power receiver (800) is mounted.

[0332] The power receiving unit (800) that is mounted on the mounting unit (482) and wirelessly receives power from the power supply unit (900) can supply power to the first lighting device (500) through the first wiring (461) and supply power to the second lighting device (700) through the second wiring (462).

[0333] For example, one side of the power receiver (800) is connected to the first wiring (461), and the first wiring (461) extends to the first opening (451) formed in the front of the side frame body (410), so that it can be electrically connected to the first lighting device (500) located in the front of the side frame (400).

[0334] In this case, one or more fixing ribs (470) may be arranged on the inside of the side frame body (410) to fix the first wiring (461).

[0335] The other side of the power receiver (800) is connected to the second wiring (462), and the second wiring (462) extends to the second opening (452) formed at the rear of the side frame body (410) and can be electrically connected to the second lighting device (700) located at the rear of the side frame (400).

[0336] Hereinafter, a refrigerator according to another embodiment will be described with further reference to FIGS. 14 to 17. Any details that overlap with those previously described will be omitted, and the omitted details can be applied to the refrigerator according to another embodiment described below.

[0337] A refrigerator (1) according to another embodiment may include a first door (901) and a second door (902) for opening and closing a first storage compartment (21), and a third door (903) for opening and closing the second storage compartment. The first storage compartment (21) may be positioned above the second storage compartment. The first door (901) and the second door (902) may be rotary doors that open and close the open front of the first storage compartment (21) by pivoting. The third door (903) may be a drawer-type door that opens and closes the open front of the second storage compartment in a forward-backward pull-out manner.

[0338] The first door (11) may be a double door type including a main door (901a) that opens and closes the first storage room (21), and a sub-door (901b) that is rotatably arranged on the front of the main door (901a) to open and close the front of the main door (901a). A door light (911) may be mounted on the sub-door (901b). One or more basket assemblies (50) may be mounted on the main door (901a), and a basket light (912) may be arranged on each basket assembly (50). For example, the basket light (912) may be implemented as various types of lighting that may be arranged on the bottom or side of the basket assembly (50) to irradiate light onto the basket assembly (50). The door light (911) and the basket light (912) can be implemented in the same manner as the first lighting device (500) or the second lighting device (700) described above, but are not limited thereto.

[0339] One or more high-intensity lighting units (71) may be placed inside the first storage room (21) to illuminate the inside of the first storage room (21).

[0340] In addition, the first storage room (21) may be provided with one or more storage sections (61) capable of storing food. For example, the storage sections (61) may include a first storage section (61a) and a second storage section (61b) disposed below the first storage section (61a). Storage section lights (913) may be disposed in each of the first storage section (61a) and the second storage section (61b). For example, the storage section lights (913) may be implemented as various types of lights that are disposed on the lower surface or side surface of the first storage section (61a) and the second storage section (61b) and can irradiate light to the first storage section (61a) and the second storage section (61b). The storage section lights (913) may be implemented in the same manner as the first lighting device (500) or the second lighting device (700) described above, but are not limited thereto.

[0341] The first storage unit (61a) and the second storage unit (61b) may be drawer-type storage units that can be pulled out and inserted in the front-back direction. The first storage unit (61a) and the second storage unit (61b) may be guided to be pulled out and inserted in the front-back direction by rails located on each of their respective sides. For example, the storage unit lighting (913) may be fixed to the rails to irradiate light onto the first storage unit (61a) and the second storage unit (61b), respectively. In addition, as another example, the storage unit lighting (913) may be fixed to the side of the first storage room (21) to irradiate light onto the first storage unit (61a) and the second storage unit (61b), respectively. In this case, the storage unit lighting (913) may be arranged to be fixed to the rail or the side of the first storage room (21) without being restricted from movement according to the pulling out and insertion in the front-back direction of the first storage unit (61a) and the second storage unit (61b).

[0342] In addition, one or more shelf sections (62) capable of supporting food may be arranged in the first storage compartment (21). A shelf section light (914) may be arranged in the shelf section (62). The shelf section light (914) may be a hanging section (34) including a light source (343) described in the previous embodiment, but is not limited thereto. For example, the shelf section light (914) may be implemented as various types of lighting that can be fixed to the lower surface or side surface of the shelf section (62) and irradiate light to the shelf section (62). The shelf section light (914) may be arranged in the front and rear of the shelf section (62), respectively. In this case, the shelf section light (914) may be implemented in the same manner as the first lighting device (500) or the second lighting device (700) described above, but is not limited thereto.

[0343] The shelf section (62) can be fixed by one or more shelf fixing members (621) that are mounted on the rear or side of the first storage compartment (21) and fix the shelf section (62). The shelf fixing members (621) can fix the shelf section (62) in a cantilever manner. For example, the shelf section light (914) can be fixed to the shelf fixing member (621) to irradiate light to the side of the shelf section (62). In another example, the shelf section light (914) can be fixed to the side of the first storage compartment (21) to irradiate light to the shelf section (62).

[0344] Meanwhile, the second door (902) may include a dispenser (904) that allows a user to dispense ice or water without opening the door. A dispenser light (913) may be placed on at least one side of the dispenser (904). The dispenser light (913) may be a hanging member (34) including a light source (343) as described in the previous embodiment, but is not limited thereto. For example, the dispenser light (913) may be implemented as various types of lighting that can be fixed to one or more of the top, bottom, and side surfaces of the dispenser (904) and irradiate light onto the dispenser (904). In this case, a first dispenser light (9131) may be arranged on the upper surface of the dispenser (904), a pair of second dispenser lights (9132) may be arranged on each of the two sides of the dispenser (904), and a third dispenser light (9133) may be arranged on the lower surface of the dispenser (904). For example, when a user approaches the refrigerator (1) and a proximity sensor detects this, the first dispenser light (9131), the second dispenser light (9132), and the third dispenser light (9133) may all be set to turn on. Also, for another example, if the dispenser light (913) and the light sensor of the refrigerator (1) are linked, when the light level is high, the first dispenser light (9131), the second dispenser light (9132), and the third dispenser light (9133) may all be turned on, but when the light level is low, only some of the first dispenser light (9131), the second dispenser light (9132), and the third dispenser light (9133) may be set to be turned on.

[0345] For example, referring to FIG. 17, the second door (902) may include a front plate (920) forming an exterior, and a door liner (940) positioned on the rear side of the front plate (920) to form a substantial body of the second door (902). A dispenser housing (930) in which a dispenser (904) is mounted may be positioned between the front plate (920) and the door liner (940). The dispenser housing (930) may be mounted and housed in the door liner (940). The front plate (920) may include a first opening (921) that can expose the dispenser (904) to the outside. The dispenser housing (930) may be formed with a second opening (931) positioned on at least one of the top, bottom, and side surfaces of the dispenser (904). A dispenser light (913) can be placed in the second opening (931).

[0346] The second opening (931) and the dispenser light (913) mounted in the second opening (931) may be positioned so as not to be directly exposed to the outside through the first opening (921). For example, the second openings (931) formed on the upper and lower surfaces of the dispenser housing (930) may be positioned so as to face each other, and the second openings (931) formed on both sides may be positioned so as to face each other. The dispenser light (913) may be embedded and fixed within an insulating material foamed between the dispenser housing (930) and the door liner (940), and the light of the dispenser light (913) may be emitted to the outside through the second opening (931). When the dispenser light (913) is turned on, the light of the dispenser light (913) emitted through the second opening (931) can be emitted to the outside through the first opening (921).

[0347] FIG. 18 is a drawing showing a screen according to another embodiment implemented in a remote device or display unit.

[0348] For example, the door light (911) may be set as a light mounted on the sub-door of the upper right door, and the basket light (912) may be set as a light mounted on the basket assembly of the upper right door. The dispenser light (913) may be set as a light mounted on the upper left door. However, this is not limited thereto, and the door light (911) and the basket light (912) may be mounted on the upper left door or the lower door. In addition, the dispenser light (913) may be mounted on the upper right door.

[0349] The door light (911), basket light (912), and dispenser light (913) can be turned on or off by linking with various types of detection devices, such as a first detection device, a second detection device, and a third detection device. For example, the detection devices can use various sensors, such as an infrared sensor, an ultrasonic sensor, or a laser sensor. The first detection device can be a proximity detection device that senses the proximity of a user by measuring the distance from the user, the second detection device can be a knock detection device that senses the door knock operation of the user, and the third detection device can be an illuminance detection device that senses the proximity of a user through changes in illuminance.

[0350] For example, a door light setting screen (951) for controlling the door light (911) and a basket light setting screen (952) for controlling the basket light (912) may be provided. In this case, setting values ​​related to the second detection device (252), such as not only on / off but also knock-on brightness and time adjustment, may be set. In addition, a dispenser light setting screen (953) for controlling the dispenser light (913) may also be provided. In this case, setting values ​​for on / off may be provided, but are not limited thereto, and various setting values, such as knock-on brightness and time adjustment, may be set.

[0351] In addition, a scenario A setting screen (954) in which door lighting (911) and basket lighting (912) are linked to each other, a scenario B setting screen (955) in which door lighting (911), basket lighting (912), and dispenser lighting (913) are linked to each other, and a scenario C setting screen (956) in which lighting is linked according to changes in illuminance, etc. may be provided. Through these scenario setting screens, it is also possible to set the linked operation of door lighting (911), basket lighting (912), and dispenser lighting (913) according to various situations.

[0352] For example, when the first detection device (251) detects the user's approach, a scenario can be set in which the door light (911) lights up and, after 3 seconds, the basket light (912) sequentially lights up.

[0353] For another example, when the second detection device (252) detects the user's door knock operation, a scenario can be set in which the door light (911) emits red light and the basket light (912) emits red light sequentially or simultaneously in the same color as red or in a complementary color to red.

[0354] As another example, when the first detection device (251) detects the user's approach, a scenario can be set in which the door light (911), basket light (912), and dispenser light (913) light up simultaneously.

[0355] For another example, if the third detection device (253) detects a change in illumination, a scenario in which the door light (911) and the basket light (912) turn on may be set. For example, in a case where the ambient illumination is high, such as during the day, since the surroundings of the refrigerator (1) are bright, the door light (911) and the basket light (912) may both be set to turn on together. In addition, in a case where the ambient illumination is low, such as at night, since the surroundings of the refrigerator (1) are dark, the door light (911) may be kept off and only the basket light (912) may be turned on, so that the inside of the refrigerator (1) can be sufficiently seen.

[0356] Additionally, a shelf lighting setting screen (957) for controlling shelf lighting (914) may be provided. In this case, on / off setting values ​​may be provided, but are not limited thereto, and various setting values ​​such as knock-on brightness and time adjustment may also be set.

[0357] Figure 19 illustrates a flowchart according to an exemplary scenario for controlling the light emission of various types of lights.

[0358] After the start step, a step (S110) in which the detection sensor of the refrigerator (1) operates may be performed. In this case, the detection sensor may be one of the first detection device, the second detection device, and the third detection device.

[0359] When the detection sensor is activated, a step (S120) of measuring the distance between the user and the refrigerator (1) and comparing it with a preset distance may be performed by the control unit. If the distance between the user and the refrigerator (1) is greater than or equal to the preset distance, a step (S121) of turning on the basket light (912) may be performed. That is, if the distance between the user and the refrigerator (1) is somewhat far, only the basket light (912) may be turned on. If the distance between the user and the refrigerator (1) is less than the preset distance, a step (S130) of determining whether the basket light (912) and / or the dispenser light (913) are set to turn on simultaneously with the door light (911) may be performed. That is, if the distance between the user and the refrigerator (1) is somewhat close, the basket light (912) and / or the dispenser light (913) may be turned on in addition to the door light (911). When each light is turned on, it can mean not only a state in which the brightness of the light is maintained continuously, but also a state in which the brightness of the light changes, such as dimming or flickering.

[0360] At this time, if it is set to be On at the same time, a step (S131) ​​may be performed in which the door light (911) is turned on simultaneously with the basket light (912) and / or the dispenser light (913). At this time, if it is not set to be On at the same time, a step (S140) may be performed in which the basket light (912) and / or the dispenser light (913) are sequentially turned on after a predetermined time after the door light (911) is turned on. In this case, the setting of whether to be On at the same time can be preset by the user on a remote device or display unit.

[0361] After one of steps (S121), (S131), and (140) is performed, a step (S150) may be performed to determine whether the detection sensor is continuously operating within a preset time or whether the door is open. In this case, if the detection sensor is continuously operating within the preset time or the door is opened, step (S151) may be performed. Step (S151) may include various types of scenario steps, such as a step (S1511) in which the basket light (912) and the dispenser light (913) and / or the door light (911) are turned off simultaneously, a step (S1512) in which the basket light (912) is sequentially turned off after the dispenser light (913) and / or the door light (911) are turned off, and a step (S1513) in which the dispenser light (913) and / or the door light (911) are turned off and the basket light (912) remains on. In the case of step (S151) where a user opens the door or stands in front of the refrigerator (1) for a long period of time, the external lights, i.e., the dispenser light (913) and the door light (911), may be turned off, but the basket light (912) inside the refrigerator (1) may be set to not turn off more quickly than the dispenser light (913) and the door light (911). Accordingly, the basket light (912) may be set to turn off simultaneously with the dispenser light (913) and the door light (911), to turn off later, or to not turn off at all.

[0362] After step (S151), a step (S160) of determining whether the door is closed is performed, and if the door is closed, a step (S170) of determining whether the basket light (912) is on may be performed. After this, if the basket light (912) is on, the process proceeds to a step (S171) of turning the basket light (912) off and then to a termination step, and if the basket light (912) is off, the process proceeds directly to the termination step.

[0363] Meanwhile, if the detection sensor does not operate continuously within a preset time or the door is closed, step (S180) may be performed. For example, this may be assumed to be the case where the user approaches the refrigerator (1) and looks only at the inside, or knocks on the door and then looks only at the inside. Step (S180) may include a step (S181) in which the basket light (912), the dispenser light (913), and / or the door light (911) are turned off simultaneously, and a step (S182) in which the basket light (912) is sequentially turned off after the dispenser light (913) and / or the door light (911) are turned off. Even in this case, the basket light (912) inside the refrigerator (1) may be set not to turn off faster than the dispenser light (913) and the door light (911). Accordingly, the basket light (912) may be turned off simultaneously with the dispenser light (913) and the door light (911), or may be turned off later. After step (S180) is performed, the process may proceed to the end step.

[0364] In the flowchart according to the scenario of one embodiment of controlling the light emission of various types of lights described above, another embodiment may be provided that also includes shelf lights (914). In this case, the shelf lights (914) in the scenario described above may be implemented in various ways, such as being turned on / off in the same manner as one of the basket lights (912), the dispenser lights (913), and the door lights (911), being turned on / off in a manner that replaces one of the lights, or being turned on / off independently regardless of the on / off control method of the lights.
