For example, the third lighting device (163) may be coupled to the lower surface (112) of the shelf plate (110). The third lighting device (163) may have a shape extending in the left-right direction of the shelf plate (110). The third lighting device (163) may include a plurality of third light-emitting members (163a) arranged toward the lower side of the shelf plate (110). The plurality of third light-emitting members (163a) may be arranged in the longitudinal direction of the third lighting device (163). Therefore, the third light-emitting members (163a) of the third lighting device (163) may emit light toward the lower side of the selection plate (110) to illuminate the storage compartment (11). The third light-emitting member (163a) is composed of RGB LEDs and can shine in various colors and can also be changed to a set color.

[0098] The shelf (100) may further include a shelf wire (170) connecting the shelf lighting device (160) and the shelf terminal portion (153). The shelf wire (170) may include a first shelf wire (171) connecting the first lighting device (161) and the shelf terminal portion (153), a second shelf wire (172) connecting the second lighting device (162) and the shelf terminal portion (153), and a third shelf wire (173) connecting the third lighting device (163) and the shelf terminal portion (153). As described above, the shelf wire (170) may be arranged across the internal space (140c) of the side frame (140) and the internal space (150c) of the shelf mounting portion (150).

[0099] The shelf mounting member (200) may include a mounting member fixing portion (210) fixed to the shelf connector (300) and a mounting member protrusion portion (220) protruding forward from the mounting member fixing portion (210).

[0100] The mounting member fixing portion (210) may have a mounting member fixing hole (211) formed into which a fastening member for fixing the shelf connector (300) is fastened.

[0101] The mounting member protrusion (220) may include an upper mounting hole (221) and a lower mounting hole (222) that are open in the front-back direction. A first protrusion (151) may be inserted into the upper mounting hole (221), and a second protrusion (152) may be inserted into the lower mounting hole (222).

[0102] The upper mounting hole (221) and the lower mounting hole (222) are provided in multiple numbers and can be arranged in the length direction of the shelf mounting member (200). The size of the upper mounting hole (221) can be formed corresponding to the size of the first protrusion (151), and the size of the lower mounting hole (222) can be formed corresponding to the size of the second protrusion (152).

[0103] For example, the upper mounting hole (221) may include a first upper mounting hole (221a) located on the upper side and a second upper mounting hole (221b) located on the lower side. The lower mounting hole (222) may include a first lower mounting hole (222a) located on the upper side and a second lower mounting hole (222b) located on the lower side.

[0104] For example, when the first protrusion (151) is inserted into the first upper mounting hole (221a), the second protrusion (152) is inserted into the first lower mounting hole (222a), and the shelf (100) can be mounted on the shelf mounting member (200). When the first protrusion (151) is inserted into the second upper mounting hole (221b), the second protrusion (152) is inserted into the second lower mounting hole (222b), and the shelf (100) can be mounted on the shelf mounting member (200). Therefore, the distance between the first upper mounting hole (221a) and the first lower mounting hole (222a) and the distance between the second upper mounting hole (221b) and the second lower mounting hole (222b) can be substantially the same.

[0105] Meanwhile, the second upper mounting hole (221b) may be located between the first upper mounting hole (221a) and the first lower mounting hole (222b), and the first lower mounting hole (222a) may be located between the second upper mounting hole (221b) and the second lower mounting hole (222b).

[0106] Accordingly, by inserting the shelf mounting portion (150) of the shelf (100) into one pair of the plurality of upper mounting holes (221) and lower mounting holes (222) formed in the shelf mounting member (200), the vertical position of the shelf (100) can be easily adjusted.

[0107] A shelf connector (300) may be coupled to the rear of the shelf mounting member (200). The shelf connector (300) may include a connector fixing portion (310) fixed to the shelf mounting member (200) and a connector protrusion (320) protruding forward from the connector fixing portion (310).

[0108] The connector fixing portion (310) may be formed with a connector fixing hole (311) into which a fastening member for fixing to the shelf mounting member (200) is fastened. The fastening member may be fastened by passing through the connector fixing hole (311) and the mounting member fixing hole (211).

[0109] The connector protrusion (320) may include an upper recessed portion (321) formed recessed rearward at a position corresponding to the upper mounting hole (221) of the shelf mounting member (200) and a lower recessed portion (322) formed recessed rearward at a position corresponding to the lower mounting hole (222) of the shelf mounting member (200).

[0110] For example, the upper recessed portion (321) may include a first upper recessed portion (321a) corresponding to the first upper mounting hole (221a) and a second upper recessed portion (321b) corresponding to the second upper mounting hole (221b). The lower recessed portion (322) may include a first lower recessed portion (322a) corresponding to the first lower mounting hole (222a) and a second lower recessed portion (322b) corresponding to the second lower mounting hole (222b).

[0111] A connector terminal portion (330) may be arranged in the lower recessed portion (322). The connector terminal portion (330) may be connected to a shelf power wire (14a) so that power may be supplied from the control unit (14). When the shelf (100) is mounted on the shelf mounting member (200), the shelf terminal portion (153) may be connected to the connector terminal portion (330). Through this, power supplied from the control unit (14) may be supplied to the shelf lighting device (160) of the shelf (100).

[0112] For example, when a shelf (100) is mounted on a shelf mounting member (200), the shelf terminal portion (153) formed of a pogo pin is contracted, and the end of the shelf terminal portion (153) can come into contact with the connector terminal portion (330). Meanwhile, without being limited thereto, the connector terminal portion (330) may also be formed of a pogo pin.

[0113] The connector terminal portion (330) is located on the rear inner side of the lower mounting hole (222) and thus cannot be seen from the front. That is, the connector terminal portion (330) for supplying power to the shelf (100) is not visible from the front, thereby improving the interior appearance of the cabinet. In addition, since the connector terminal portion (330) is located on the rear inner side of the lower mounting hole (222), the introduction of foreign substances can be prevented. Through this, a stable connection between the shelf terminal portion (153) and the connector terminal portion (330) can be further ensured.

[0114] The shelf terminal portion (153) or connector terminal portion (330) may be configured as a pogo pin. Accordingly, when the shelf (100) is mounted on the shelf mounting member (200), the shelf terminal portion (153) of the shelf (100) can naturally come into contact with the connector terminal portion (330) of the shelf connector (300). Through this, power supplied from the control unit (14) to the connector terminal portion (330) can be supplied to the shelf lighting device (160) of the shelf (100). In other words, power can be supplied to the shelf lighting device (160) of the shelf (100) with a simplified structure.

[0115] Hereinafter, another embodiment of the positional relationship between the shelf terminal portion (153) and the connector terminal portion (330) will be described.

[0123] Referring to Fig. 8, in the shelf (100) according to the present embodiment, the shelf terminal portion (153') may be positioned on the lower surface of the second protrusion (152). According to the present embodiment, the connector terminal portion (330) of the shelf connector (300) may be positioned to correspond to the shelf terminal portion (153') when the shelf (100) is mounted on the shelf mounting member (200). For example, the connector terminal portion (330) may be positioned on the lower surface of the lower recessed portion (322).

[0124] In the present embodiment, when the shelf terminal portion (153') is inserted into the lower mounting hole (222), the end of the shelf terminal portion (153') may have a rounded shape in order to minimize interference with the shelf mounting member (200). Through the above structure, the second protrusion (152) provided on the lower surface of the pogo pin-shaped shelf terminal portion (153') can be easily inserted into the lower mounting hole (222) and the lower recessed portion (322).

[0125] Fig. 9 is a cross-sectional view showing the connection relationship between a shelf and a cabinet according to another embodiment.

[0126] In the shelf (100) according to the present embodiment, the shelf terminal portion (153'') may be positioned on the side of the second protrusion (152). According to the present embodiment, the connector terminal portion (330) of the shelf connector (300) may be positioned to correspond to the shelf terminal portion (153') when the shelf (100) is mounted on the shelf mounting member (200). For example, the connector terminal portion (330) may be positioned on the inner surface of the lower recessed portion (322).

[0127] In the present embodiment, when the shelf terminal portion (153'') is inserted into the lower mounting hole (222), the end of the shelf terminal portion (153'') may have a rounded shape in order to minimize interference with the shelf mounting member (200). Through the above structure, the second protrusion (152) provided on the lower surface of the pogo pin-shaped shelf terminal portion (153') can be easily inserted into the lower mounting hole (222) and the lower recessed portion (322).

[0128] Fig. 10 is a cross-sectional view showing the connection relationship between a shelf and a cabinet according to another embodiment.

[0129] Referring to Fig. 10, the shelf (100) and the shelf connector (300) may be configured to wirelessly transmit and receive power. For example, a power receiving device (153''') may be provided inside the second protrusion (152) of the shelf (100), and a power transmitting device (330''') may be provided at the rear of the lower recessed portion (322) of the shelf connector (300). According to the present embodiment, when the shelf (100) is mounted on the shelf mounting member (200) through the above structure, power can be stably supplied to the shelf (100).

[0130] Fig. 11 is an exploded perspective view showing the connection relationship between a door basket and a door according to one embodiment.

[0131] The coupling relationship between the shelf (100), shelf mounting member (200) and shelf connector (300) described above can be equally applied to the door basket (23) provided on the door (20).

[0132] Referring to Fig. 11, in the present embodiment, a basket mounting member (400) on which a door basket (23) is mounted may be further provided on the rear wall of the door liner (22) of the door (20). The basket mounting member (400) may be provided vertically and elongated on the rear wall of the door liner (22). The front of the basket mounting member (400) may be exposed and may form a portion of the rear wall of the door liner (22).

[0133] In this embodiment, a basket connector (500) for providing power may be further provided at the rear of the basket mounting member (400). A plurality of basket connectors (500) may be provided, and may be provided at positions where the basket (23) may be mounted. A basket power wire (14b) connected to the control unit (14) to provide power may be connected to the basket connector (500). When the basket (23) is mounted on the basket mounting member (400), the basket (23) may be connected to the basket connector (500) to receive power provided from the control unit (14).

[0134] The door basket (23) may include a basket body (231), a basket frame (232), a basket lighting device (233), and a basket mounting portion (234).

[0135] The basket body (231) can provide a storage space (231a) for storing food.

[0136] A basket frame (232) may be coupled to the lower part of the front end of the basket body (231). A basket lighting device (233) may be provided between the basket body (231) and the basket frame (232). The basket frame (232) is made of a material that transmits light and may cover the basket lighting device (233) from the lower side.

[0137] The basket lighting device (233) may have a shape extending in the left and right directions of the basket body (231). The basket lighting device (233) may include a plurality of basket light-emitting members (233a) arranged toward the lower side of the basket body (231). The plurality of basket light-emitting members (233a) may be arranged in the longitudinal direction of the basket lighting device (233). Therefore, the basket light-emitting members (233a) of the basket lighting device (233) may emit light toward the lower side of the basket body (231) to illuminate the rear of the door liner (22).

[0138] The basket mounting portion (234) may have a shape that protrudes rearward from both left and right sides of the basket body (231). The basket mounting portion (234) may include a first basket protrusion (235) located on the upper side and a second basket protrusion (236) located on the lower side. A basket terminal portion (237) may be provided at the rear of the second basket protrusion portion (236). The basket terminal portion (237) may be connected to the basket lighting device (233) by a basket wire (237a).

[0139] The basket mounting member (400) may include an upper basket mounting hole (410) and a lower basket mounting hole (420) that are open in the front-back direction. A first basket protrusion (235) may be inserted into the upper basket mounting hole (410), and a second basket protrusion (236) may be inserted into the lower basket mounting hole (420).

[0140] The upper basket mounting hole (410) and the lower basket mounting hole (420) are provided in multiple numbers and can be arranged in the length direction of the basket mounting member (400). The size of the upper basket mounting hole (410) can be formed corresponding to the size of the first basket protrusion (235), and the size of the lower basket mounting hole (420) can be formed corresponding to the size of the second basket protrusion (236).

[0141] For example, when the first basket protrusion (235) is inserted into the first upper basket mounting hole (410a), the second basket protrusion (236) is inserted into the first lower basket mounting hole (420a), and the basket (23) can be mounted on the basket mounting member (400). When the first basket protrusion (235) is inserted into the second upper basket mounting hole (410b), the second basket protrusion (236) is inserted into the second lower basket mounting hole (420b), and the basket (23) can be mounted on the basket mounting member (400). Accordingly, the spacing between the first upper basket mounting hole (410a) and the first lower basket mounting hole (420a) and the spacing between the second upper basket mounting hole (410b) and the second lower basket mounting hole (420b) may be the same.

[0142] Meanwhile, the second upper basket mounting hole (410b) may be located between the first upper basket mounting hole (410a) and the first lower basket mounting hole (420b), and the first lower basket mounting hole (420a) may be located between the second upper basket mounting hole (410b) and the second lower basket mounting hole (420b).

[0143] Therefore, by inserting the basket mounting portion (234) of the basket (23) into the upper basket mounting hole (410) and the lower basket mounting hole (420) formed in the basket mounting member (400), it is possible to easily adjust the upper and lower position of the basket (23).

[0144] A basket connector (500) may be coupled to the rear of the basket mounting member (400). The basket connector (500) may include a connector fixing portion (510) fixed to the basket mounting member (400) and a connector protrusion portion (520) protruding forward from the connector fixing portion (510).

[0145] The connector fixing member (510) may include a plurality of fixing holes (511) for fixing a fastening member to be fixed to the basket mounting member (400).

[0146] The connector protrusion (520) may include an upper basket recessed portion (521) formed recessed rearward at a position corresponding to the upper basket mounting hole (410) of the basket mounting member (400) and a lower basket recessed portion (522) formed recessed rearward at a position corresponding to the lower basket mounting hole (420) of the basket mounting member (400).

[0147] For example, the upper basket recess (521) may include a first upper basket recess (521a) corresponding to the first upper basket mounting hole (410a) and a second upper basket recess (521b) corresponding to the second upper basket mounting hole (410b). The lower basket recess (522) may include a first lower basket recess (522a) corresponding to the first lower basket mounting hole (420a) and a second lower basket recess (522b) corresponding to the second lower basket mounting hole (420b).

[0148] A connector terminal portion (530) may be arranged in the lower basket recess (522). The connector terminal portion (530) may be connected to a basket power wire (14a) so that power may be supplied from the control unit (14). When the basket (23) is mounted on the basket mounting member (400), the basket terminal portion (237) may be connected to the connector terminal portion (530). Through this, power supplied from the control unit (14) may be supplied to the basket lighting device (233) of the basket (23).

[0149] For example, when the basket (23) is mounted on the basket mounting member (400), the basket terminal portion (237) formed of a pogo pin is contracted, and the end of the basket terminal portion (237) can come into contact with the connector terminal portion (530). Meanwhile, without being limited thereto, the connector terminal portion (530) may also be formed of a pogo pin.

[0150] The connector terminal portion (530) is located on the rear inner side of the lower basket mounting hole (420) and thus cannot be seen from the front. That is, the connector terminal portion (530) for supplying power to the basket (23) is not visible from the front, thereby improving the internal appearance of the device. In addition, since the connector terminal portion (530) is located on the rear inner side of the lower basket mounting hole (420), the phenomenon of foreign substances being introduced can be prevented. Through this, a stable connection between the basket terminal portion (237) and the connector terminal portion (530) can be further ensured.

[0151] The basket terminal portion (237) or connector terminal portion (530) may be configured as a pogo pin. Accordingly, when the basket (23) is mounted on the basket mounting member (400), the basket terminal portion (237) of the basket (23) can naturally come into contact with the connector terminal portion (530) of the basket connector (500). Through this, power supplied from the control unit (14) to the connector terminal portion (530) can be supplied to the basket lighting device (233) of the basket (23). In other words, power can be supplied to the basket lighting device (233) of the basket (23) with a simplified structure.

[0152] Fig. 12 is a front view of a refrigerator according to another embodiment.

[0153] Referring to Fig. 12, a refrigerator (1') according to the present embodiment may include a partition wall (15) that partitions a storage compartment (11). The storage compartment (11) may include a first storage compartment (11a) arranged on the left side and a second storage compartment (11b) arranged on the right side based on the partition wall (15).

[0154] Each of the first storage room (11a) and the second storage room (11b) may be equipped with a shelf (100). In addition, shelf mounting members (200, 201) may be equipped on both sides of the rear wall of each of the first storage room (11a) and the second storage room (11b).

[0155] In the present embodiment, the first shelf mounting member (200) described above with reference to FIGS. 1 to 3 may be positioned on the outer side of the rear wall of each of the first storage compartment (11a) and the second storage compartment (11b). Meanwhile, the second shelf mounting member (201) may be positioned on the inner side of the rear wall of each of the first storage compartment (11a) and the second storage compartment (11b). That is, the second shelf mounting member (201) may be positioned adjacent to the partition wall (15).

[0156] The coupling relationship between the first shelf mounting member (200) and the second shelf mounting member (200) and the shelf (100) is substantially the same as that described above with reference to FIGS. 1 to 10, and therefore, detailed descriptions thereof will be omitted in the description of this embodiment.

[0157] Through the above structure, the appearance of the refrigerator (1') can be improved by placing the first shelf mounting member (200) including the shelf terminal portion (153) on an outside side where it is not visible.

[0158] Hereinafter, the control of the lighting device (160, 233, 4500, 3000') through the user terminal device (600) and the control unit (14) will be described with reference to FIGS. 13 and 14.

[0159] Fig. 13 is a block diagram illustrating a control signal flow of a refrigerator according to one embodiment. Fig. 14 is a schematic diagram illustrating a user terminal device controlling a refrigerator according to one embodiment.

[0160] Referring to FIGS. 13 and 14, a user can control the control unit (14) via a user terminal (600) to control the lighting devices (160, 233, 4500, 3000') included in the refrigerator (1). For example, the lighting devices (160, 233, 4500, 3000') of the refrigerator (1) may include the shelf lighting device (160) and basket lighting device (233) described above with reference to FIGS. 1 to 12, and the door lighting devices (4500, 3000') described below with reference to FIGS. 15 to 20.

[0161] Hereinafter, the control of the lighting devices (160, 233, 4500, 3000') of the refrigerator (1) will be described based on the shelf lighting device (160) provided on the shelf (100), but the contents thereof can also be applied to other lighting devices (233, 4500, 3000').

[0162] The user can select a shelf (100) to be controlled through a user terminal (600) and control the color, lighting time, lighting brightness, etc. of the shelf lighting device (160) provided on the shelf (100).

[0163] In one embodiment, a user terminal device (600) may display a refrigerator (1) having shelves (100a, 100b, 100c). For example, the shelves (100a, 100b, 100c) may include a first shelf (100a) positioned at the top, a second shelf (100b) positioned in the middle, and a third shelf (100c) positioned at the bottom. The first to third shelves (100a, 100b, 100c) may have the same structure. The first to third shelves (100a, 100b, 100c) may have any one of the structures described above with reference to FIGS. 1 to 10.

[0164] Shelves (100a, 100b, 100c) may be equipped with shelf lighting devices (160). A user may control the operation of the shelf lighting devices (160) by selecting at least one of the shelves (100a, 100b, 100c) displayed on the refrigerator (1). For example, a menu for selecting the shelves (100a, 100b, 100c) to be controlled may be displayed in the form of a checkbox on the user terminal (600).

[0165] For example, the user terminal device (600) may include a menu (601) for selecting a color of the shelf lighting device (160), a menu (602) for selecting a lighting time zone, and a menu (603) for selecting lighting brightness.

[0166] Through this, the refrigerator (1) according to the present embodiment can improve aesthetics by controlling the shelf lighting device (160) to light up in a color desired by the user, and can improve user convenience by controlling the lighting time and lighting brightness. Of course, the above-mentioned elements such as the color, lighting time and lighting brightness can be set differently for each shelf (100a, 100b, 100c). Therefore, customization of the lighting device (160) included in the shelf (100) of the refrigerator (1) is possible, and thus the satisfaction of the user using the refrigerator (1) can be improved.

[0167] In addition, the shelf lighting devices (160) included in the shelves (100a, 100b, 100c) of the refrigerator (1) can be controlled so that the operating elements such as lighting color, lighting time period, and lighting brightness are mutually linked. For example, the operating elements such as lighting color, lighting time period, and lighting brightness of the shelf lighting devices (160) included in the shelves (100a, 100b, 100c) can be controlled identically.

[0168] In addition, the operating elements of the shelf lighting devices (160) included in the shelves (100a, 100b, 100c) may be controlled differently. For example, the lighting colors of the shelf lighting device (160) included in the first shelf (100a) and the shelf lighting device (160) included in the second shelf (100b) may be complementary to each other. The lighting time periods and lighting brightness of the shelf lighting device (160) and the basket lighting device (233) may be set differently.

[0169] Hereinafter, a structure of a door lighting device (4500, 3000') that can be controlled in conjunction with a shelf lighting device (160) provided on the above-described shelf (100) will be described. Specifically, a door lighting device (4500) that provides light from the top to the bottom of a sub-door (4000) will be described with reference to FIGS. 15 to 17, a door lighting device (4500) that provides light from the top to the bottom of a sub-door (4000) will be described with reference to FIGS. 18 to 20, and a door lighting device (3000') that provides light on both sides of a door (2000') will be described.

[0170] FIGS. 15 to 17 are drawings illustrating a door lighting device of one embodiment that is controlled in conjunction with a shelf lighting device according to one embodiment.

[0171] Referring to FIGS. 15 to 17, a refrigerator (1000) according to the present embodiment includes a cabinet (1100) in which a storage space is formed and a door (2000) for opening and closing the storage space.

[0275] Fig. 31 is a flowchart showing a method for controlling a refrigerator according to another embodiment.

[0276] Referring to FIG. 31, a method for controlling a refrigerator according to the present embodiment may include a step of comparing an indoor illuminance with a reference illuminance to determine which of the first and second lights to turn on. In addition, a method for controlling a refrigerator according to the present embodiment may include a step of comparing an elapsed time for turning on the first or second lights with a reference time, or determining whether a door is opened to determine whether to turn off the first or second lights.

[0277] In the control method of a refrigerator according to the present embodiment, the first light and the second light may refer to different lighting devices (160, 233) capable of illuminating the interior of the refrigerator (1) when the door is closed. For example, the first light may refer to a basket lighting device (see '233' of FIG. 11), and the second light may refer to a door lighting device (see '4500' of FIG. 17).

[0278] A method for controlling a refrigerator according to the present embodiment may include a step of sensing a user's operation (S11), a step of sensing indoor illuminance (S21), a step of comparing the indoor illuminance with a reference illuminance (S31), a step of turning on a first light or a second light (S41, S42), a step of measuring the lighting elapsed time using a timer (S51), a step of comparing the lighting elapsed time with a reference time (S61), and a step of determining whether a door is opened (S62).

[0279] First, a step (S11) of sensing a user's operation may be performed. Here, the user's operation may refer to an operation for turning on the first light or the second light. For example, the user's operation may include any one of the following: knocking on a door, approaching the door, operating a switch to turn on a light, or turning on a light using a terminal device.

[0280] After the step of sensing the user's operation (S11), a step of sensing indoor illuminance (S21) may be performed. The step of sensing indoor illuminance (S21) may be a step of sensing the illuminance of an indoor space in which a refrigerator (1) is placed. The step of sensing indoor illuminance (S21) may be performed by an illuminance sensor (not shown) provided in the refrigerator (1). For example, the illuminance sensor may be placed at the upper part of the refrigerator (1).

[0281] After the step of sensing the indoor illuminance (S21), a step of comparing the indoor illuminance with a reference illuminance (S31) may be performed. The step of comparing the indoor illuminance with the reference illuminance (S31) may be a step of determining whether the sensed indoor illuminance is greater than or less than a preset reference illuminance.

[0282] If the indoor illuminance is higher than the reference illuminance, a step (S41) of turning on both the first light and the second light may be performed. That is, if the indoor illuminance is higher than the reference illuminance, both the first light and the second light may be turned on to further illuminate the inside of the refrigerator (1).

[0283] Meanwhile, if the indoor illuminance is lower than the reference illuminance, a step (S42) may be performed in which either the first light or the second light is turned on. That is, if the indoor illuminance is lower than the reference illuminance, either the first light or the second light may be turned on to prevent glare to the user. At this time, which of the first light and the second light is turned on may be set by the user.

[0284] After the step (S41) in which both the first light and the second light are turned on, a step (S51) in which the lighting elapsed time is measured using a timer may be performed. In the step (S51) in which the lighting elapsed time is measured using a timer, the time at which the first light and the second light are turned on may be measured.

[0285] The step (S51) of measuring the lighting elapsed time using a timer can also be performed after the step (S42) in which either the first light or the second light is turned on.

[0286] During the step (S51) of measuring the lighting elapsed time using a timer, a step (S61) of comparing the lighting elapsed time with a reference time may be performed in real time. The step (S61) of comparing the lighting elapsed time with the reference time may be a step of determining whether the lighting elapsed time measured in the step (S51) of measuring the lighting elapsed time using a timer is greater than or less than a preset reference time.

[0287] In the step (S61) of comparing the lighting elapsed time with the reference time, if the lighting elapsed time is greater than or equal to the reference time, the step (S71) of turning off the first light and the second light that have been turned on can be performed.

[0288] Meanwhile, in the step (S61) of comparing the lighting elapsed time with the reference time, if the lighting elapsed time is less than or equal to the reference time, a step (S62) of determining whether the door is open may be performed. The step (S62) of determining whether the door is open may be performed to turn off the first light and the second light when the door is opened, even if the lighting elapsed time is less than or equal to the reference time.

[0289] In the step (S62) of determining whether the door is open, if the door is determined to be open, the step (S72) of turning off the first and second lights that are turned on may be performed. For example, when the door is opened, the interior lighting device that illuminates the inside of the storage room is turned on, so that the lighting of the first and second lights that operate when the door is closed may become unnecessary. Accordingly, unnecessary power consumption can be prevented when the door is opened.

[0290] Meanwhile, in the step (S62) of determining whether the door is open, if it is determined that the door is not open, the process can return to the step (S61) of comparing the lighting elapsed time with the reference time.

[0291] According to the refrigerator control method according to the present embodiment, multiple lights (first lights and second lights) of the refrigerator (1) can be controlled in conjunction with the indoor illuminance and whether the door is open. This prevents glare to the user and unnecessary power consumption.

[0292] According to a refrigerator according to an embodiment of the present invention, the appearance can be improved by arranging the power connector provided to supply power to a lighting device provided on a shelf so as not to be visible, and thus, the possibility of industrial application is recognized.

[0293] According to a refrigerator according to an embodiment of the present invention, a refrigerator in which a shelf equipped with a lighting device can be easily combined and separated can be provided, and thus, its industrial applicability is recognized.

[0294] According to a refrigerator according to an embodiment of the present invention, power for the lighting device can be stably supplied to a shelf equipped with a lighting device even when the coupling position of the shelf is changed, and thus, industrial applicability is recognized.

[0295] According to a refrigerator according to an embodiment of the present invention, the lighting device provided on the shelf and other light-emitting devices of the refrigerator are linked to set the appearance according to the user's preference, and thus, industrial applicability is recognized.
