[0075] That is, the refrigerator door 10 according to the embodiment of the present disclosure may include a color module 500 configured to display color of the refrigerator door by using LEDs. Accordingly, the color of the refrigerator door 10 may be changed to a color desired by a consumer when the consumer desires a particular color

[0076] Hereinafter, each component of the refrigerator door 10 according to the embodiment of the present disclosure will be described in more detail.

[0077] First, the refrigerator door 10 according to the embodiment of the present disclosure may include a door frame 100.

[0078] The door frame 100 may be configured as the outer body of the refrigerator door 10. That is, the door frame 100 may constitute the front wall surface of the refrigerator door 10.

[0079] The door frame 100 may be formed of a metal plate, or may be formed of an injection molded product of synthetic resin.

[0080] Protruding ends 110 may be formed on the door frame 100 by protruding forward therefrom. For example, the protruding ends 110 may be formed respectively on one side and the remaining one side of the peripheries of the front surface of the door frame 100. In this case, each of the protruding ends 110 may be formed to be integrated with the front surface of the door frame 100 or may be manufactured separately from the door frame 100 so as to be attached, fused, contacted, or combined with the front surface of the door frame 100.

[0081] The front surfaces of the two protruding ends 110 may be configured respectively as the front edges of the opposite sides of the refrigerator door 10. That is, when the refrigerator door 10 is viewed from the front side, the front surfaces of the two protruding ends 110 may constitute the front edges of the refrigerator door 10.

[0082] The door frame 100 may be formed of various materials.

[0083] For example, the door frame 100 may be formed of a metal plate. In this case, the protruding end 110 may be formed by bending the opposite ends of the door frame 100 forward.

[0084] For example, the door frame 100 may be formed of synthetic resin. In this case, the protruding ends 110 may be configured as integral structures formed by protruding forward respectively from the opposite edges of the front surface of the door frame 100.

[0085] In addition, as illustrated in FIG. 4, a partitioning protrusion 111 may be formed on the inner surface of each of the two protruding ends 110. The partitioning protrusion 111 may be a structure for installing the color module 500 to be described later, and the color module 500 may be located between the partitioning protrusions 111 and the front surface of the door frame 100.

[0086] In this case, the partitioning protrusion 111 may be configured to protrude by having such a length (height) that the color module 500 is not removed forward unintentionally. That is, the partitioning protrusion 111 may be configured to cover the opposite edges of the front surface of the color module 500. Accordingly, the color module 500 may be removed from or coupled to the door frame 100 in a vertical direction.

[0087] The partitioning protrusion 111 may be configured to be located by being spaced apart from an end of each of the two protruding ends 110. In this case, a distance by which partitioning protrusion 111 is spaced apart from the end of the protruding end may be the thickness of the tempered glass 610. That is, a seating portion in which the tempered glass 610 can be installed may be provided on the front of the partitioning protrusion 111 between the two protruding ends 110.

[0088] Next, the refrigerator door 10 according to the embodiment of the present disclosure may include an inner frame 200 (see FIG. 3).

[0089] The inner frame 200 may be configured as the inner body of the refrigerator door 10. That is, the inner frame 200 may constitute the rear wall surface of the refrigerator door 10.

[0090] A storage box 201 may be installed on the wall surface of such an inner frame 200 located at the inside of the refrigerator.

[0091] In addition, the inner frame 200 may be located to be spaced apart from the door frame 100. That is, space may be defined between the inner frame 200 and the door frame 100 such that an insulation member 300 to be described later fills the space.

[0092] Next, the refrigerator door 10 according to the embodiment of the present disclosure may include the insulation member 300 (see FIGS. 3 to 5).

[0093] The insulation member 300 may be provided to prevent heat exchange between room temperature and the internal temperature of the refrigerator.

[0094] The insulation member 300 may be provided between the door frame 100 and the inner frame 200, and accordingly, heat exchange between the door frame 100 and the inner frame 200 may be prevented.

[0095] The insulation member 300 may be configured as foam (for example, PU foam). In this case, in a state in which the door frame 100 and the inner frame 200 are provided, the foam may be filled between the two frames 100 and 200 so as to form the insulation member 300.

[0096] Of course, although not shown, the insulation member 300 may be configured as a separate member from each of the frames 100 and 200 and may be located between the two frames 100 and 200 to be coupled or attached to the two frames 100 and 200, or may be omitted.

[0097] Meanwhile, the opposite sides of the door frame 100 and the inner frame 200 may be configured to be covered by side wall frames 620, respectively. That is, the side wall frames 620 may respectively constitute the opposite wall surfaces of the refrigerator door 10, and accordingly, the door frame 100 and the inner frame 200 may be maintained to be spaced apart by a predetermined distance from each other, and a foam may be filled between the door frame 100 and the inner frame 200 so as to form the insulation member 300.

[0098] In this case, each of the side wall frames 620 may be provided separately from the door frame 100 or the inner frame 200 and may be configured to simultaneously cover the two frames 100 and 200. Of course, although not shown, the side wall frame 620 may be configured to completely cover any one frame of the two frames 100 and 200 and to cover only at least a portion of the remaining one frame, or may be configured to cover only a portion of each of the two frames 100 and 200.

[0099] Such a side wall frame 620 may be formed of a thin metal plate or a synthetic resin.

[0100] Of course, the side wall frame 620 may be omitted, and the opposite ends of at least any one frame of the door frame 100 and the inner frame 200 may be respectively bent to cover the side surfaces of the remaining frame.

[0101] Next, the refrigerator door 10 according to the embodiment of the present disclosure may include cover frames 410 and 420.

[0102] The cover frames 410 and 420 may include the upper cover frame 410 for constituting an upper wall surface of the refrigerator door 10. In this case, the upper cover frame 410 may be configured to cover the upper end of each of the door frame 100 and the inner frame 200 and may be provided as the upper wall surface of the refrigerator door 10.

[0103] The cover frames 410 and 420 may include the lower cover frame 420 for constituting a lower wall surface of the refrigerator door 10. In this case, the lower cover frame 420 may be configured to cover the lower end of each of the door frame 100 and the inner frame 200 and may be provided as the lower wall surface of the refrigerator door 10.

[0104] Both of the upper cover frame 410 and the lower cover frame 420 may be provided simultaneously. Although not shown, only one of the upper cover frame 410 and the lower cover frame 420 may be provided.

[0105] As illustrated in FIGS. 3 and 5, the first mounting grooves 411 and 421 may be formed to face each other in the cover frames 410 and 420, respectively, so as to install the door frame 100. That is, the upper and lower ends of the door frame 100 may be received in the first mounting grooves 411 and 421, respectively, and may be maintained to be coupled to the two cover frames 410 and 420, respectively.

[0106] In this case, the first mounting grooves 411 and 421 may be formed in the cover frames 410 and 420, respectively, by being recessed therefrom, or two protrusions spaced apart from each other may be formed on each of the cover frames 410 and 420 by protruding therefrom such that furrows defined between the two protrusions constitute the first mounting grooves 411 and 421.

[0107] In addition, second mounting grooves 412 and 422 for the installation of the color module 500 may be formed to face each other in the cover frames 410 and 420, respectively. That is, the upper and lower ends of the color module 500 may be received in the second mounting grooves 412 and 422, respectively, and may be maintained to be coupled to the two cover frames 410 and 420, respectively.

[0108] In this case, the second mounting grooves 412 and 422 may be configured to be located in front of the first mounting grooves 411 and 421, respectively. Accordingly, the color module 500 may be located on the front surface of the door frame 100.

[0109] The second mounting grooves 412 and 422 may be formed in the cover frames 410 and 420, respectively, by being recessed therefrom or may be formed by protrusions formed to be lower than protrusions for forming the first mounting grooves 411 and 421. Of course, separate protrusions may be additionally formed to form the second mounting grooves 412 and 422.

[0110] In addition, as illustrated in FIGS. 3 and 5, the glass receiving parts 413 and 423 for installing the tempered glass 610 may be formed to face each other in the cover frames 410 and 420, respectively.

[0111] Such glass receiving parts 413 and 423 may be formed by protruding forward from the second mounting grooves 412 and 422, respectively such that the tempered glass 610 can be received in portions of the front sides of the second mounting grooves 412 and 422 formed in the cover frames 410 and 420. The tempered glass 610 may function to protect the color module 500 installed on the front surface of the door frame 100 located inside the cover frames 410 and 420 from an external environment.

[0112] In this case, the front surfaces of the glass receiving parts 413 and 423 may be configured respectively as the upper and lower front edges of the refrigerator door 10. That is, the glass receiving parts 413 and 423 and the front surfaces of the two protruding ends 110 may constitute the front edges of the refrigerator door 10.

[0113] Meanwhile, the cover frames 410 and 420 and the side wall frames 620 are preferably formed of opaque materials through which light does not pass. That is, light supplied from the color module 500 to be described later may not pass through the cover frames 410 and 420 and the side wall frame 620, but may emit only forward.

[0114] Next, the refrigerator door 10 according to the embodiment of the present disclosure may include the color module 500.

[0115] The color module 500 may be an LED module that displays a color desired by a user. Such a color module 500 may be provided on the front surface of the door frame 100.

[0116] That is, in the embodiment of the present disclosure, rather than changing the color of the surface of the refrigerator door by replacing the color module 500, the color of the surface of the refrigerator door 10 may be changed by controlling color expressed in the color module 500 through a controller (not shown) or a mobile app. Accordingly, the inconvenience of a prior art in which when changing the color of the front surface of the refrigerator door 10, the refrigerator door 10 having the color or the front surface thereof (for example, a decorative panel) is required to be replaced may be released.

[0117] The color module 500 may include an LED board 510 constituting a light source, and a light guide plate 520 which evenly spreads light provided from the light source (the LED board) over an entire screen thereof.

[0118] Here, the LED board 510 may be configured as a substrate configured such that multiple RGB LEDs 511 are mounted on the surface of the substrate.

[0119] In addition, the LED board 510 may be located on any one portion around the light guide plate 520. Specifically, the LED board 510 may be located on any one portion of the upper and lower sides of the light guide plate 520.

[0120] For example, as illustrated in FIG. 5, the LED board 510 may be located inside the upper cover frame 410, and the multiple LEDs 511 mounted on the LED board 510 may be configured to be located on the upper side of the light guide plate 520 such that the multiple LEDs 511 emit light toward the light guide plate 520.

[0121] In addition, as illustrated in FIGS. 6 to 8, the connector 512 may be formed on any one side of the LED board 510. In this case, a cable (not shown) for the luminescence control of each of the LEDs 511 mounted on the LED board 510 and power supply thereto may be connected to the connector 512.

[0122] Particularly, the connector 512 may be configured to be exposed through the side wall frame 620 to the outside, and thus the operation control of the LED board 510 may be performed by the controller of the refrigerator.

[0123] Meanwhile, a cover protrusion 414 (see FIG. 5) may be formed in front of the second mounting groove 412 of the upper cover frame 410 receiving the LED board 510.

[0124] The cover protrusion 414 may be configured to prevent the installation portion of the LED board 510 from being exposed to the front surface of the refrigerator door. Although not shown, when the LED board 510 is located at the lower cover frame 420, the cover protrusion 414 may be formed in front of the second mounting groove 422 of the lower cover frame.

[0125] Particularly, the cover protrusion 414 may be formed to have enough length to cover a periphery of the light guide plate 520. That is, the cover protrusion 414 may be configured to have enough length to cover the opposing portions of the peripheral surface of the light guide plate 520 and the LED 511. Accordingly, the cover protrusion 414 may cover a portion of each of the LEDs 511 mounted on the LED board 510 from which light begins to be emitted, so light leakage may be prevented.

[0126] Of course, the cover protrusion 414 is preferably configured to have length in consideration of the light leakage and a color display area as wide as possible.

[0127] In addition, the light guide plate 520 and a diffusing plate 530 may be provided in the second mounting grooves 412 and 422. That is, light guided by the light guide plate 520 may be diffused more widely through the diffusing plate 530. Of course, the light guide plate 520 and the diffusing plate 530 may be formed as a single body.

[0128] Although not shown, hinges (not shown) may be installed on the upper cover frame 410 and the lower cover frame 420, respectively. The hinges are components which couple the associated refrigerator door 10 rotatably to the refrigerator body.

[0129] Meanwhile, the support part 120 which supports the rear surface of the light guide plate 520 may be formed on the front surface of the door frame 100.

[0130] That is, since the light guide plate 520 is formed of a plate material, the light guide plate 520 may be easily bent and deformed, so display defects may occur due to refraction of light. In consideration of this, the support part 120 may be used such that the light guide plate 520 has a precisely flat surface.

[0131] The support part 120 may be formed partially on the front surface of the door frame 100. That is, the support part 120 may include a plurality of support parts. The plurality of support parts 120 may be formed on the front surface of the door frame 100 by being spaced apart from each other in a transverse or longitudinal direction of the door frame 100.

[0132] Particularly, the support part 120 described above may be formed by protruding a portion of the front surface of the door frame 100 forward. When the door frame 100 is formed of a metal plate, a portion of the door frame 100 may be punched and bent to form the support part 120.

[0133] Although not shown, the support part 120 may be formed separately from the door frame 100 and then attached to or coupled to the front surface of the door frame 100 so as to be integrated therewith.

[0134] In addition, the tempered glass 610 may be located in the glass receiving parts 413 and 423 of the cover frames 410 and 420 located in front of the cover protrusion 414.

[0135] The tempered glass 610 is a cover which protects the color module 500 from an external environment.

[0136] The tempered glass 610 may be formed of transparent glass or colored glass. Of course, the tempered glass 610 may be formed of a light-passable synthetic resin (a transparent synthetic resin or a colored synthetic resin).

[0137] The tempered glass 610 may be attached to and fixed to the front surface of the color module 500 by the adhesive member 611 (see FIG. 5). Although not shown, the coupling of the tempered glass 610 may be performed by a separate fastening member (for example, screws, etc.), or the opposing surfaces of the peripheral surface of the tempered glass 610 and the inner surface of the upper cover frame 410 may be glued to each other to be fastened to each other. Although not shown, the ends of the upper cover frame 410 may be additionally bent to prevent the removal of the tempered glass 610 therefrom.

[0138] The adhesive member 611 may be provided on the opposing wall surfaces of the tempered glass 610 and the color module 500. For example, as illustrated in FIG. 4, the adhesive member 611 may be provided on the opposing surfaces of the partitioning protrusion 111 and the tempered glass 610, and as illustrated in FIG. 5, may be provided on the opposing surfaces of the cover protrusion 414 and the tempered glass 610.

[0139] Hereinafter, the manufacturing process of the refrigerator door 10 according to the embodiment of the present disclosure described above will be described with reference to FIGS. 9 to 13.

[0140] First, as illustrated in FIGS. 9 and 10, the door frame 100 is prepared.

[0141] The door frame 100 described above may be manufactured through a press process or may be manufactured through an injection process. For example, when the door frame 100 is formed of metal, the door frame 100 may be manufactured through the press process, and when the door frame 100 is formed of synthetic resin, the door frame 100 may be manufactured through the injection process. Of course, when the door frame 100 is formed by mixing metal with synthetic resin, the door frame 100 may be manufactured by a double injection process after the press process.

[0142] Next, the color module 500 is prepared.

[0143] The color module 500 may be provided such that the light guide plate 520, the diffusing plate 530, and the LED board 510 have structure separate from each other. Of course, although not shown, the light guide plate 520, the diffusing plate 530, and the LED board 510 may be provided as an integral structure.

[0144] Furthermore, the prepared the light guide plate 520 and the diffusing plate 530 of the color module 500 may be inserted between the two protruding ends 110 formed on the door frame 100. Specifically, the light guide plate 520 and the diffusing plate 530 may be installed to be located between the front surface of the door frame 100 and the partitioning protrusions 111 formed on the protruding ends 110, respectively, and the diffusing plate 530 may be located on the front surface of the light guide plate 520. This is illustrated in FIGS. 11 and 12.

[0145] In this case, since the plurality of support parts 120 is formed on the front surface of the door frame 100, the light guide plate 520 and the diffusing plate 530 may be mounted to be flat without bending between the front surface of the door frame 100 and the partitioning protrusions 111.

[0146] In addition, in a state in which the light guide plate 520 and the diffusing plate 530 are completely mounted, the cover frames 410 and 420 may be coupled respectively to the upper and lower ends of each of the door frame 100 and the inner frame 200.

[0147] After the coupling of the cover frames 410 and 420, the door frame 100 may be inserted into and mounted to the first mounting grooves 411 and 421 formed in the cover frames 410 and 420, respectively, and the color module 500 may be inserted into and mounted to the second mounting grooves 412 and 422 formed in the cover frames 410 and 420, respectively. This is illustrated in FIGS. 12 and 13.

[0148] In this case, the LED board 510 may be located inside the second mounting groove 412 such that LED light is emitted toward the upper surface of the light guide plate 520.

[0149] The LED board 510 constituting the color module 500 may be installed to be located inside the second mounting grooves 412 and 422 in various methods.

[0150] For example, in a state in which the LED board 510 is prefixed (for example, attached) to the upper surface of the light guide plate 520, the coupling of the upper cover frame 410 may be performed such that the LED board 510 is located inside the second mounting groove 412.

[0151] Alternatively, in a state in which the cover frames 410 and 420 are coupled to the door frame 100 and the inner frame 200, the LED board 510 may pass through the side wall frame 620 such that the LED board 510 is located in the second mounting groove 412 formed in the upper cover frame 410.

[0152] Alternatively, in a state in which the LED board 510 is located in advance in the second mounting groove 412 formed in the upper cover frame 410, the upper cover frame 410 may be coupled to the door frame 100 and the inner frame 200.

[0153] In addition, in a state in which the color module 500 is installed between the door frame 100, the cover frames 410 and 420, and the side wall frames 620, the tempered glass 610 may be mounted to the front surface of the color module 500. This is illustrated in FIGS. 4 and 5.

[0154] The tempered glass 610 may be attached to the color module 500 by using the adhesive member 611. That is, the adhesive member 611 may be attached to the edge of the front surface of the diffusing plate 530 therealong and then the tempered glass 610 may be attached to the front surface of the diffusing plate. In a case in which the diffusing plate 530 is not provided, the tempered glass 610 may be attached to the front surface of the light guide plate 520.

[0155] Of course, the adhesive member 611 may be configured to be attached to each of the opposing surfaces of the front surface of the partitioning protrusion 111 and the tempered glass 610.

[0156] Furthermore, as described above, when the assembly of the door frame 100 with the color module 500 is completed, the inner frame 200 and the side wall frames 620 are prepared. In this case, the inner frame 200 and the side wall frames 620 described above may be manufactured and provided through manufacturing processes different from the manufacturing process of the door frame 100.

[0157] Additionally, the prepared the inner frame 200 may be disposed to be spaced apart in a front-to-rear direction from the door frame 100 and then the side wall frames 620 may be coupled to the opposite sides thereof, respectively.

[0158] Accordingly, the door frame 100 and the inner frame 200 may be maintained to be spaced apart by a predetermined distance from each other.

[0159] Furthermore, the insulation member 300 may be formed between the door frame 100 and the inner frame 200. The insulation member 300 may be formed by filling space between the door frame 100 and the inner frame 200 with foam (for example, PU foam). This is illustrated in FIGS. 4 and 5.

[0160] Accordingly, through the above-described process, the refrigerator door 10 according to the embodiment of the present disclosure may be completely manufactured.

[0161] Meanwhile, the color module 500 of the refrigerator door 10 may be connected to the controller of the refrigerator (not shown) such that the color module 500 is controlled by the controller.

[0162] For example, the connector 512 of the color module 500 and the controller may be connected to each other by a cable (a signal line) (not shown) such that the LED board 510 of the color module 500 is controlled by the controller, so the color module 500 may light the LED 511 in a specific color. Furthermore, the color module 500 may be controlled to be turned on/off and thus can display colors only when needed.

[0163] In addition, considering that the controller can be manipulated by a user, it is possible to change the color of the refrigerator to the same color as surrounding furniture or other devices.

[0164] In addition, it is possible to update information on realizable colors through a dedicated application while the controller is connected online.

[0165] As described above, the refrigerator door 10 of the present disclosure may be expressed in color desired by a user by using the multiple LEDs 511, and thus color of the refrigerator door may be easily changed.

[0166] Particularly, the refrigerator door 10 of the present disclosure may have color changed by being manipulated by a user. Accordingly, even without replacing the entirety of the refrigerator door 10 or the front surface of the refrigerator door 10, the refrigerator door 10 (or the front surface) may be expressed in color desired by a user.

[0167] In addition, a structure for the installation of the color module 500 may be installed to be integrated with the front surface of the refrigerator door 10 of the present disclosure, thereby preventing problems such as the inconvenience of assembly of the refrigerator door and the increase of the thickness of the refrigerator door due to an increased structure which are caused by providing the structure for installing the color module 500 separately from the refrigerator door 10.

[0168] In addition, in the refrigerator door 10 of the present disclosure, the LED board 510 may be located in the cover frames 410, and may be configured to be covered by the cover protrusion 414, so the light leakage may be prevented.

[0169] In addition, in the refrigerator door 10 of the present disclosure, the tempered glass 610 may be received in the glass receiving parts 413 and 423 and may be configured to be bonded to the partitioning protrusions 111 or the front surface of the color module 500, so the thickness of the refrigerator door 10 may be minimized and a work for the installation of the tempered glass 610 may be facilitated.

[0170] In addition, in the refrigerator door 10 of the present disclosure, the plurality of support parts 120 may be formed on the front surface of the door frame 100 to support the light guide plate 520, and thus the light guide plate 520 may have a precisely flat surface, so color defects due to the bending deformation of the light guide plate 520 may be prevented.

[0171] Meanwhile, the refrigerator door 10 of the present disclosure may be embodied in various forms other than a structure according to the above-described embodiment.

[0172] For example, although not shown, in the refrigerator door 10 of the present disclosure, the LED board 510 may be installed inside each of the protruding ends 110 of the door frame 100. That is, the LED board 510 may be located on any one side wall of the light guide plate 520 and may be configured as the light source.

[0173] In this case, the partitioning protrusion 111 formed on the protruding end 110 is preferably formed to have enough length to prevent the exposure of the LED board 510 and light leakage.

[0174] In addition, although not shown, the side wall frames 620 of the refrigerator door 10 of the present disclosure may be configured to cover the opposite wall surfaces of the door frame 100 from the opposite wall surfaces of the inner frame 200, or to cover the opposite wall surfaces of the inner frame 200 from the opposite wall surfaces of the door frame 100.

[0175] In addition, although not shown, in the refrigerator door 10 of the present disclosure, at least one of the inner frame 200 and the insulation member 300 may be omitted.

[0176] For example, an empty space may be defined between the door frame 100 and the inner frame 200.

[0177] Alternatively, the inner frame 200 and the door frame 100 may be configured to be integrated with each other.

[0178] In addition, although not described or shown in the embodiment, the refrigerator door 10 of the present disclosure may be embodied by including all the components (the door frame, the inner frame, the insulation member, the cover frames, and the color module) mentioned in the above-described embodiment, or may be embodied by including only some components.

[0179] Accordingly, the refrigerator door of the present disclosure may be embodied in various forms.
