[0029] In the following, specific embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the present invention is not limited to the embodiments in which the concept of the present invention is presented, and other regressive inventions or other embodiments that fall within the scope of the concept of the present invention can be easily proposed by adding, changing, or deleting further components.

[0030] Before explaining, let's define the directions. In the embodiments of the present invention, the direction in which the front of the door shown in Figure 1 faces can be defined as "forward," the direction in which the cabinet faces relative to the front of the door is "rear," the direction in which the floor on which the refrigerator is installed faces is "downward," and the direction away from the floor is "upward."

[0031] Furthermore, when describing an undefined direction, the direction can be redefined and explained based on each drawing.

[0032] Figure 1 is a front view of a refrigerator according to an embodiment of the present invention. As shown in the figures, the refrigerator 1 according to an embodiment of the present invention may include a cabinet 10 that forms a storage space and a door 20 that opens and closes the storage space.

[0033] For example, the cabinet 10 may have a storage space divided into upper and lower sections. The storage space may be divided into an upper storage space and a lower storage space. The upper storage space may be a refrigerator compartment, and the lower storage space may be a freezer compartment. The cabinet 10 may also be equipped with a control unit (11 in Figure 17) that controls the overall operation of the refrigerator 1. The control unit 11 may be called the main PCB.

[0034] The door 20 may include an upper door 21 that opens and closes the upper storage space and a lower door 22 that opens and closes the lower storage space. The upper door 21 may be called a refrigerator door or a first door. The lower door 22 may be called a freezer door or a second door. The upper door 21 and the lower door 22 may be configured as a pair of doors, with both left and right ends connected to the cabinet 10 by hinge devices, so that the storage space is opened and closed by rotation.

[0035] A display window is formed on at least a portion of the front surface of the upper door 21. The display window 312 allows selective viewing of the space behind the upper door 21. The display window may be called a screen or a viewing section. The display window 312 can output an image via a display 33 provided on the door 21. The display window 312 may be formed on each of the pair of upper doors 21 on the left and right sides. Of course, the display window 312 may be formed on only one of the upper doors 21.

[0036] The structure of the upper door 21 will be described in more detail below with reference to the drawings. For the sake of clarity, the upper door 21 may be referred to simply as door 21.

[0037] Figure 2 is a perspective view of the door. Figure 3 is an exploded perspective view from the front showing the door panel assembly and door body separated. Figure 4 is an exploded perspective view from the rear showing the door panel assembly and door body separated.

[0038] As shown in the figure, the door 21 may include a panel assembly 30 and a door body 40. The panel assembly 30 may have a structure that allows it to be attached to and detached from the door body 40. For example, the panel assembly 30 can be easily attached to and detached from the door body 40 without the need to fasten fasteners such as screws and bolts using separate tools. This facilitates maintenance and assembly of the panel assembly 30.

[0039] The door body 40 may include a front frame 41 that forms the front, a door liner 42 that forms the rear, side frames 45 that form both sides, and an upper cap 43 and a lower cap 44 that form the upper and lower ends.

[0040] The door body 40 may include a body panel assembly 50. The body panel assembly 50 may consist of a plurality of transparent panels that allow visibility to the rear of the door. The body panel assembly 50 may be called a second panel assembly to distinguish it from the panel assembly 30.

[0041] The body panel assembly 50 may be positioned in the center of the door body 40. The body panel assembly 50 can also form part of the front and rear surfaces of the door body 40.

[0042] The front frame 41 has a frame opening 411 through which the body panel assembly 50 passes. The door liner 42 has a liner opening 421 through which the body panel assembly 50 passes. Therefore, the front surface of the body panel assembly 50 can be exposed through the frame opening 411, and the rear surface of the body panel assembly 50 can be exposed through the liner opening 421. A gasket 46 may be provided around the door liner 42.

[0043] The front frame 41 is formed with side restraint portions 412 for mounting the panel assembly 30. Side restraint protrusions 343 and 634, provided on both sides of the panel assembly 30, are inserted into the side restraint portions 412. Multiple side restraint portions 412 may be formed vertically along both sides of the body panel assembly 50.

[0044] Furthermore, the upper cap 43 and the lower cap 44 are connected to the upper and lower ends of the panel assembly 30, thereby restraining the upper and lower ends of the panel assembly 30. Therefore, when the panel assembly 30 is mounted on the door body 40, its upper and lower ends, as well as both left and right ends, are restrained, maintaining a stable connected state.

[0045] Furthermore, the front surface of the door body 40, i.e., a portion of the front frame 41, can form a recessed housing space 401, thereby accommodating the PCB assemblies 60, 70, and 80 that protrude from the rear surface of the panel assembly 30.

[0046] Furthermore, although not shown in the figures, a lighting device (111 in Figure 17) may be provided. The operation of the lighting device 111 illuminates the space behind the door 21, making it possible to see through to the space behind through the display window 312. For example, the lighting device 111 may be provided on one side of the door liner 42 or the door body 40. As another example, the lighting device 111 may be provided on one side of the cabinet 10.

[0047] The panel assembly 30 can be detachably coupled to the door body 40 and form the front of the door 21. The panel assembly 30 may be called the door panel assembly 30. The panel assembly 30 may be called the second panel assembly 30 to distinguish it from the body panel assembly 50. The panel assembly 30 may include a front panel 31 that forms the front, a display 33 behind the front panel 31, and a number of PCB assemblies 60, 70, 80.

[0048] The front panel 31 may be made of a transparent material and configured to be see-through. For example, the front panel 31 may be made of glass material. In embodiments of the present invention, transparent can be defined to include not only complete transparency but also a semi-transparent state in which the rear space can be seen through. In embodiments of the present invention, opaque can be defined to include not only complete opacity but also a state in which the shape of the rear space is difficult to discern.

[0049] A display window 312 is formed in the center of the front panel 31. The space behind the door 21 can be seen through the display window 312, and at the same time, the screen output of the display 33 is visible from the outside.

[0050] A bezel 311 is formed around the front panel 31. The bezel 311 is formed along the display window 312 to conceal the rear space. A number of PCB assemblies 60, 70, 80 arranged along the display 33 are located in the area of ​​the bezel 311 and are concealed by the bezel 311.

[0051] The PCB assembly may include a first PCB assembly 80 located above the display 33, a second PCB assembly 70 located below the display 33, and a third PCB assembly 60 provided on one of the left or right sides of the display 33.

[0052] A side guide 34 may be provided on the other side of the left and right sides of the display 33. The side guide 34 may be provided on one side of the left and right sides of the panel assembly 30 that corresponds to the hinge mounting portion 432 at the upper end of the door 21.

[0053] The panel assembly 30 will be described in more detail below with reference to the drawings.

[0054] Figure 5 is an exploded perspective view of the panel assembly. Figure 6 is a rear view of the panel assembly. Figure 7 is a perspective view of the first PCB assembly, which is one component of the panel assembly. Figure 8 is a perspective view of the second PCB assembly, which is one component of the panel assembly.

[0055] As shown in the illustration, the panel assembly 30 may include a front panel 31, a display 33, and a number of the PCB assemblies 60, 701, 80. The panel assembly 30 may further include a touch sensor 32 for sensing user touch operations.

[0056] The touch sensor 32 is positioned between the front panel 31 and the display 33. For example, the touch sensor 32 may be formed in the shape of a film, with its front surface in contact with the front panel 31 and its rear surface in contact with the display 33. The touch sensor 32 may be formed at a position corresponding to the display window 312, and may be formed to a corresponding size or slightly larger.

[0057] Furthermore, a touch cable 321 for transmitting signals from the touch sensor 32 may be provided at the upper end of the touch sensor 32. For example, the touch cable 321 may be made of an FFC (Flat Flexible Cable). That is, the touch cable 321 may be formed as a film or a flexible plate and may be connected to the first PCB assembly 80 located above it.

[0058] The display 33 may be composed of a transparent display panel that allows rearward visibility and screen output, and can be called a transparent display. The display 33 can also be called a display panel. For example, the display 33 may be composed of a transparent OLED panel. In particular, by installing the panel assembly 30 containing the transparent OLED after injecting the foaming liquid into the door body 40, damage to the expensive OLED due to foaming heat can be prevented. Furthermore, the transparent OLED can be exposed when separating the panel assembly 30, making service of the expensive transparent OLED easier.

[0059] The display 33 may be fixedly attached to the front panel 31. Therefore, when the panel assembly 30 is separated and mounted, the numerous PCB assemblies 60, 70, and 80, including the display 33, can remain coupled to the front panel 31.

[0060] The display 33 may be formed to a size corresponding to or slightly larger than the display window 312. The area around the display 33 is spaced apart from the front panel 31 and can provide space for the numerous PCB assemblies 60, 70, 80 to be mounted along the perimeter of the display 33.

[0061] A third PCB assembly 60 may be positioned at one of the left or right ends of the display 33, and the third PCB assembly 60 may be connected to the side end of the display 33 by a display cable 331. For example, the display cable 331 may be made of an FFC (Flat Flexible Cable). The third PCB assembly 60 may be formed on the side of the panel assembly 30 that is furthest from the hinge mounting portion 432. The third PCB assembly 60 can be positioned between one end of the display 33 and the front panel 31. A portion of the third PCB assembly 60 may overlap with the side end of the display 33.

[0062] The side guide 34 may be provided on the other side of the display 33, which is either the left or right side. The side guide 34 is positioned between the side edge of the display 33 and the side edge of the front panel 31.

[0063] The first PCB assembly 80 is positioned between the upper edge of the display 33 and the upper edge of the front panel 31. The first PCB assembly 80 can control the overall configuration of the panel assembly 30. The first PCB assembly 80 may consist of a combination of multiple PCBs.

[0064] More specifically, the first PCB assembly 80 may include a first PCB bracket 80 mounted on the rear surface of the front panel 31 and a plurality of PCBs 81, 82, 83, 84 mounted on the first PCB bracket 80.

[0065] The first PCB bracket 80 may be formed in a plate shape. An upper restraint portion 802 and an upper restraint groove 803 are formed at the upper end of the first PCB bracket 80. Multiple upper restraint grooves 803 may be arranged along the upper end of the first PCB bracket 80. When the cap cover 48 is attached, the upper restraint projection 483 formed on the cap cover 48 is inserted and can restrain the upper end of the panel assembly 30.

[0066] The first PCB bracket 80 may include a panel PCB 81, a touch PCB 82, and a converter PCB 83. Furthermore, the first PCB bracket 80 may also include a thread PCB 84.

[0067] The panel PCB 81 may be configured to be directly or indirectly connected by cables to a number of PCBs 82, 83, and 84 as a configuration for controlling the overall drive of the panel assembly 30. A panel cable 911 may be connected to the panel PCB 81, which extends to the outside of the door and connects to the control unit 11 of the cabinet 10. A connector 910 is provided at one end of the panel cable 911 so that it can be easily disconnected and connected to the door cable 921 provided on the door body 40 when separating and installing the panel assembly 30.

[0068] The converter PCB 83 may be provided for signal conversion between the panel PCB 81 and the scale PCB 71 of the second PCB assembly 70. The converter PCB 83 may be located separately from the panel PCB 81, or it may be connected to the panel PCB 81 by a first connecting cable 912. The converter PCB 83 may also be connected to the scale PCB 71 by a second connecting cable 913. In this case, the second connecting cable 913 can pass through the side guide 34 and through the cable guide 342 of the side guide 34.

[0069] The thread module 84 may be provided on one side of the panel PCB 81. Furthermore, the thread module 84 may be configured on a separate PCB and connected to the panel PCB 81 by a fourth connecting cable 915 for communication with external devices.

[0071] On the other hand, the first PCB assembly 80 may be connected to the control unit 11 by a cable. The first PCB assembly 80 may be connected to the second PCB assembly 70, and the second PCB assembly 70 may be connected to the third PCB assembly 60. That is, the third PCB assembly 60 and the second PCB assembly 70 may be directly or indirectly connected to the first PCB assembly 80, and may be connected to the control unit 11 via the first PCB assembly 80.

[0072] Below the display 33, the second PCB assembly 70 may be provided. The second PCB assembly 70 is positioned between the lower end of the display 33 and the lower end of the front panel 31. The second PCB assembly 70 is for driving the display 33 and can, in particular, control the driving of the transparent OLED panel.

[0073] More specifically, the second PCB assembly 70 may include a second PCB bracket 72 mounted on the rear surface of the front panel 31 and a scale PCB 71 mounted on the second PCB bracket 72.

[0074] The second PCB bracket 72 may be formed in a plate shape and attached to the back surface of the front panel 31. A PCB mounting portion 721 is formed at the upper end of the second PCB bracket 72, on which the scale PCB 71 is mounted.

[0075] A bracket extension portion 722 is formed at the lower end of the PCB mounting portion 721, extending downward. A lower restraint portion 723 is formed at the lower end of the bracket extension portion 722, i.e., at the lower end of the second PCB bracket 72. The lower restraint portion 723 is coupled to the lower cap 44 and can restrain the lower end of the panel assembly 30.

[0076] A lower restraint groove 725 is formed in the lower restraint portion 723, opening downward. A lower restraint projection 442, which protrudes upward from the lower cap 44, is inserted into the lower restraint groove 725. The connection between the lower restraint projection 442 and the lower restraint groove 725 maintains the lower end of the panel assembly 30 connected to the door body 40.

[0077] Furthermore, a support rib 724 is formed above the lower restraint groove 725, projecting rearward. The support rib 724 contacts the front surface of the door body 40, allowing the panel assembly 30 to maintain a stable mounting position without moving in the front-rear direction.

[0078] The third PCB assembly 60 may be connected to the side edge of the display 33. The third PCB assembly 60 may include a source PCB 611 and a T-con PCB 612, at least a portion of which may be arranged in a continuous manner. The second PCB assembly 70 may be configured in multiple layers so that a large number of PCBs 611, 612 are arranged in a confined space. The source PCB 611 and T-con PCB 612 together may be called a side PCB.

[0079] The scale PCB 71 can transmit signals from the second PCB assembly 70, which is connected to the display 33, to the converter PCB 83. One side of the scale PCB 71 may be connected to the converter PCB 83 by a second connecting cable 913. The other side of the scale PCB 71 may be connected to the third PCB assembly 60.

[0080] Figure 9 is a perspective view of the side guide. As shown in the figure, the side guide 34 extends vertically along the side of the front panel 31. The side guide 34 may include a plate-shaped side body 341 and a cable guide 342 and a side restraint projection 343 that project rearward from the rear surface of the side body 341.

[0081] The side body 341 may be formed in a plate shape and attached to the back surface of the front panel 31. Multiple cable guides 342 may be arranged vertically along the side body 341. Multiple cable guides 342 can be located on the same extension line. The rear of the cable guide 342 is cut open so that the second connecting cable 913 can enter and exit. The cable guide 342 is open vertically so that the second connecting cable 913 passes through the cable guide 342 and is guided vertically.

[0082] Furthermore, the side restraint projections 343 are formed in multiple locations in the vertical direction and are positioned to be insertable into the side restraint portion 412. The side restraint projections 343 can be formed in a hook shape so that they catch and restrain or press-fit restrain one side end of the panel assembly 30 inside the side restraint portion 412. The side restraint projections 343 may be arranged in multiple locations spaced apart in the vertical direction. For example, the side restraint projections 343 may be provided on the upper and lower parts of the side body 341.

[0083] Therefore, the third PCB assembly 60 is positioned around the display 33 by cables 912, 913, and 914 which connect it to the lower second PCB assembly 70 and to the upper first PCB assembly 80 via the lateral side guides 34.

[0084] The third PCB assembly 60 will be described in more detail below with reference to the drawings.

[0085] Figure 10 is an enlarged view of section A in Figure 5. Figure 11 is an exploded perspective view of the third PCB assembly, which is a component of the panel assembly. Figure 12 is a 12-12 cutaway perspective view of Figure 4.

[0086] As shown in the figure, the third PCB assembly 60 is composed of a number of PCBs 611, 612, and the PCBs 611, 612 may be stacked and aligned in a three-dimensional manner.

[0087] As an example, PCBs 611 and 612 may include a source PCB 611 connected to the display 33 and driving the display 33, and a T-con (timing controller) PCB 612 connected to the source PCB 611 and the scale PCB 71 and transmitting commands for driving the display 33 to the source PCB 611. The source PCB 611 may be called the first PCB, and the T-con PCB 612 may be called the second PCB. The T-con PCB may be called the timing control PCB.

[0088] The source PCBs 611 may be arranged in pairs, one above the other, at one end of the display 33. Each source PCB 611 is connected to the display 33 by a display cable 331. The display cable 331 may be a flat flexible cable (FFC). Multiple source PCBs 611 may be arranged vertically. Of course, more than two source PCBs 611 may be provided as needed.

[0089] The T-conPCB612 is positioned behind the source PCB611, and when viewed from the rear, the T-conPCB612 and the source PCB611 can be arranged in a stacked configuration. Furthermore, when viewed from the rear, at least a portion of the T-conPCB612 and the source PCB611 can overlap each other.

[0090] Then, one end of the source PCB 611 and one end of the T-con PCB 612 are connected by a connecting cable 62. The connecting cable 62 is made of a flexible cable and can be bent in the vertical direction to connect the left and right sides of the source PCB 611 and the T-con PCB 612, one side closer to the side end of the front panel 31. For example, the connecting cable 62 may be an FFC (Flat Flexible Cable).

[0091] In this configuration, the source PCB 611 and T-con PCB 612 can be positioned behind the area of ​​the bezel 311 while stacked in the front-to-back direction. Therefore, when viewed from the front, the T-con board 612, source PCB 611, and connecting cable 62 are not exposed.

[0092] The second PCB assembly 70 may include a source case 63 and a T-con case 64. The source case 63 and T-con case 64 may be referred to as the first case and the second case.

[0093] The source case 63 may include a first base 631 attached to the rear surface of the front panel 31 and housing the source PCB 611, and a first rib 632 projecting rearward along the circumference of the first base 631. The first rib 632 may be partially formed on a portion of the entire circumference of the first base 631. The source PCB 611 is positioned within the space formed by the first rib 632. Therefore, it will not interfere with the source PCB 611 when the T-con PCB 612 and the T-con case 64 are stacked.

[0094] A first opening 634 is formed around the first rib 632 through which the connecting cable 62 enters and exits. A case support portion 635 is formed on the first base 631 to support the T-con case 64. A fastening hole 636 is formed in the case support portion 635, which penetrates the source case 63 for fastening. Multiple case support portions 635 may be formed vertically along the first base 631. A side restraint projection 634 is formed on the first base 631, which protrudes rearward and connects to the door body 40. The side restraint projection 634 is formed in a hook-like structure and is inserted into the side restraint portion 412. Multiple side restraint projections 634 may be formed vertically along the first base 631. The side restraint projection 634 is formed at a position corresponding to the side restraint portion 412. The side restraint projection 634 may have the same shape as the side restraint projection 343 formed on the side guide 34. The side restraint projection 634 can be called a case side projection, as it is distinguished from the side restraint projection 343 formed on the side guide 34.

[0095] On the other hand, the source case 63 may be formed in a number corresponding to the number of source PCBs 611. For example, the source case 63 may be configured in two parts, each of which can accommodate one of the source PCBs 611. In this case, a connecting portion 633 may be formed at the lower end of the upper source case 63 and the upper end of the lower source case 63 to connect them to each other. Of course, the source case 63 may also be configured as a single unit, so that both source PCBs 611 are mounted in one source case 63.

[0096] The T-con case 64 may include a second base 641 located behind the source case 63 and housing the T-con PCB 612, and a second rib 642 projecting rearward along the second base 641.

[0097] The second rib 642 may be partially formed around a portion of the entire second base 641. The T-conPCB 612 is positioned within the space formed by the second rib 642. Thus, the T-conPCB 612 does not interfere with the source case 63 and source PCB 611 located below it.

[0098] A second opening 644 is formed around the second rib 642 through which the connecting cable 62 enters and exits. The T-con case 64 is formed to a size corresponding to the T-con PCB 612 and may be smaller than the source PCB 611. The T-con case 64 is positioned between a pair of vertically arranged source PCBs 611. Thus, the first opening 634 and the second opening 644 are aligned in the front-to-back direction.

[0099] Then, the second base 641 has a fastening portion 643 formed at the rear, corresponding to the case support portion 635, through which the fastening member 637 is fastened. The fastening portion 643 is recessed forward and has an opening for the screw-like fastening member 637 to pass through. When the T-con case 64 is aligned in front of the source case 63, the fastening portion 643 is aligned with the fastening hole 636.

[0100] The first PCB assembly 80, the second PCB assembly 70, the side guide 34, and the third PCB assembly 60 are arranged around the display 33, and may also be arranged around the rear surface of the front panel 31. The first PCB assembly 80, the second PCB assembly 70, the side guide 34, and the third PCB assembly 60 further protrude behind the display 33 and are housed in a recessed space in the front of the door body 40.

[0101] The mounting structure of the door body and the display 33 will be described in detail below with reference to the drawings.

[0102] Figure 13 is a cross-sectional view of section 13-13 in Figure 2. And Figure 14 is a perspective view of the incision at section 14-14 in Figure 2.

[0103] As shown in the diagram, the door body 40 is formed by filling the interior with foam liquid when the front frame 41, door liner 42, side frame 45, upper cap 43, lower cap 44, and body panel assembly 50 are joined together to form the heat insulating material 400. That is, the central part of the door body 40 is transparent to the rear space due to the body panel assembly 50, and the part of the door body 40 outside the body panel assembly 50 is insulated by the heat insulating material 400.

[0104] The body panel assembly 50 may be formed by a plurality of transparent panels. For example, the body panel assembly 50 may include a first panel 51 forming the front, a third panel 53 forming the rear, and a second panel 52 between the first panel 51 and the third panel 53. The first panel 51, the second panel 52, and the third panel 53 may be formed from a transparent glass material. Furthermore, at least a portion of the first panel 51, the second panel 52, and the third panel 53 may be made of insulated glass (Low-E glass). The first panel 51 may be called the front body panel, the second panel 52 may be called the middle body panel, and the third panel 53 may be called the rear body panel.

[0105] A first spacer 541 is provided between the first panel 51 and the second panel 52 to connect them. The first spacer 541 is formed around the first panel 51 and the second panel 52. A sealant 55 may be applied to the outside of the first spacer 541 to further seal the edges of the first panel 51, the second panel 52, and the first spacer 541. Thus, the space between the first panel 51 and the second panel 52 becomes airtight, forming a first insulation layer 501. The first insulation layer 501 may be in a vacuum or filled with an insulating gas.

[0106] A second spacer 542 is provided between the second panel 52 and the third panel 53 to connect them. The second spacer 542 is formed around the second panel 52 and the third panel 53. A sealant 55 may be applied to the outside of the second spacer 542 to further seal the ends of the second panel 52, the third panel 53 and the second spacer 542. Thus, the space between the second panel 52 and the third panel 53 becomes airtight, forming a second insulation layer 502. The second insulation layer 502 may be in a vacuum or filled with an insulating gas.

[0107] On the other hand, the body panel assembly 50 may have a structure in which a first panel 51 and a third panel 53 form a single thermal insulation space.

[0108] Furthermore, the overall thickness of the body panel assembly 50 does not protrude beyond the front end of the door body 40. The display 33 and the first panel 51 may be positioned facing each other when the panel assembly 30 is installed. When the panel assembly 30 is installed, the rear surface of the display 33 and the front surface of the first panel 51 can touch each other, and the center of the panel assembly 30 is supported by the door body 40.

[0109] On the other hand, the rear surface of the body panel assembly 50, i.e., around the third panel 53, can form an outwardly projecting projection 531. The projection 531 forms the end of the third panel 53 and can project outward beyond the second spacer 542 to contact the front frame 41. The heater 47 may be positioned on the projection 531.

[0110] More specifically, the first panel 51 and the second panel 52 are the same size, and the third panel 53 is formed to be larger than the first panel 51 and the second panel 52. Therefore, the protruding portion 531 can protrude outward more than the first panel 51 and the second panel 52.

[0111] With the body panel assembly 50 installed, the rear surface of the third panel 53 is supported in contact with the portion of the door liner 42 that forms the liner opening 421. The front surface of the third panel 53 is supported by the end of the front frame 41. That is, the protruding portion 531 protrudes outward from the liner opening 421, with its rear surface in contact with the heat insulating material 400 and its front surface in contact with the front frame 41 and the heater 47.

[0112] The body panel assembly 50 is fixed to the door body 40 by the protrusion 531, and the heater 47 is mounted on the protrusion 531 to prevent condensation inside the storage space 401.

[0113] The front area of ​​the door body 40 is formed by the front frame 41. The front frame 41 is positioned in a location corresponding to the area around the body panel assembly 50 and can form the accommodation space 401 that accommodates the configuration located on the rear surface of the panel assembly 30.

[0114] The front frame 41 may be formed in a rectangular frame shape, and the outer circumference of the front frame 41 is connected to the side frame 45, the upper cap 43, and the lower cap 44. The frame opening 411 is formed inside the front frame 41, through which the body panel assembly 50 can pass.

[0115] More specifically, the front frame 41 may include a frame side portion 414. The frame side portion 414 is connected to the side frame 45. The frame side portion 414 can be bent to support the rear surface of the front panel 31.

[0116] The front frame 41 may include a frame housing portion 410 that forms the housing space 401. The frame housing portion 410 may be bent multiple times. The frame housing portion 410 can form a multi-stage recessed space in the housing space 401. For example, the frame housing portion 410 may include a first part 415 that extends rearward and a second part 416 that extends from the first part 415 toward the body panel assembly 50. The second part 416 can form a surface that faces the rear surface of the front panel 31.

[0117] The second part 416 has a side restraint portion 412 that protrudes forward. The side restraint portion 412 has a side restraint groove 413 that is recessed to the rear. For example, the side restraint portion 412 is composed of a pair of spaced-apart ribs, and the side restraint groove 413 is formed between the side restraint portions 412. The side restraint protrusions 343 and 634 are then press-fitted into the side restraint groove 413. For this reason, the ends of the side restraint portion 412 may be formed in a hook shape that connects with the side restraint protrusions 343 and 634.

[0118] The side restraint portions 412 may be provided in multiple quantities on both the left and right sides of the front frame 41 and are formed in positions corresponding to the side protrusions 343 and 634. Therefore, when the panel assembly 30 is aligned and pushed into the storage space 401 without any additional fastening work, the left and right ends of the panel assembly 30 are fixed to the door body 40.

[0119] The frame housing 410 may include a third part 417 that extends rearward from the end of the second part 416, and the third part 417 extends to the third panel 53. The third part 417 can support the body panel assembly 50 in contact with the outer edge of the third panel 53.

[0120] A panel support portion 418 is formed on the front frame 41. The panel support portion 418 may extend from the frame housing portion 410 toward the body panel assembly 50. For example, the panel support portion 418 may extend from the third part 417. The panel support portion 418 may also extend toward the body panel assembly 50 at a position separated forward from the end of the third part 417.

[0121] The panel support portion 418 may be extended to contact the front surface of the third panel 53. The panel support portion 418 may also be extended to contact the protruding portion 531. Thus, the end of the third panel 53 is supported by the panel support portion 418 and the third part 417.

[0122] The panel support portion 418 extends to the sealant 55. A heater mounting portion 419 is formed at the end of the panel support portion 418, which houses the heater 47. The heater mounting portion 419 is recessed so that the heater 47 can be inserted. Therefore, when the heater 47 is mounted in the heater mounting portion 419, it can contact the surrounding surface of the third panel 53 and heat the end of the third panel 53.

[0123] The panel support portion 418 and the heater 47 are formed along the periphery of the body panel assembly 50. Therefore, when the heater 47 is driven, the area around the third panel 53 is heated, preventing cold air from being transmitted to the housing space 401 and preventing condensation from occurring inside the housing space 401. In other words, the PCB assemblies 60, 70, and 80 of the panel assembly 30 that are exposed inside the housing space 401 are prevented from being damaged by condensation inside the housing space 401.

[0124] The front frame 41 is injection-molded from a plastic material, and the structure for housing and securing the panel assembly 30 and the structure for securing the body panel assembly 50 can all be formed in a single configuration.

[0125] On the other hand, a lower support portion 441 protrudes from the lower cap 44 to support the lower end of the panel assembly 30. A lower restraint projection 442 is formed on the lower support portion 441, protruding upward. A lower restraint groove 725 is formed at the lower end of the second PCB bracket of the panel assembly 30 into which the lower restraint projection 442 is inserted. Therefore, when the panel assembly 30 is positioned within the housing space 401 of the door body 40, its lower end is supported by the lower support portion 441, and it can maintain a restrained state through the connection between the lower restraint projection 442 and the lower restraint groove 725.

[0126] An upper opening 431 is formed on the front surface of the upper cap 43 into which the upper restraint portion 802 of the upper end of the first PCB bracket 80 is inserted. When the panel assembly 30 is positioned on the door body 40, the upper restraint portion 802 can be positioned inside the upper cap 43. The upper restraint groove 803 formed on the upper surface of the upper restraint portion 802 can be exposed through the open upper surface of the upper cap 43. When the cap cover 48 is attached, the upper restraint projection 483 formed on the cap cover 48 is inserted into the upper restraint groove 803.

[0127] Therefore, when the panel assembly 30 is mounted on the door body 40, and the upper restraint groove 803 is exposed above the upper cap 43, the cap cover 48 can be coupled to the upper cap 43 to restrain the upper end of the panel assembly 30.

[0128] In this manner, the panel assembly 30 is constrained to the door body 40 at its upper end, lower end, and both left and right ends. With the panel assembly 30 fully installed, the rear surface of the panel assembly 30, i.e., the display 33, is supported by the front surface of the body panel assembly 50. The PCB assemblies 60, 70, and 80, which are positioned around the panel assembly 30, are placed within the housing space 401.

[0129] On the other hand, when the panel assembly 30 is installed, the cables are detachably connected for the electrical connection of the components of the panel assembly 30. In other words, the connection and disconnection of the cables are performed together when the panel assembly 30 is attached or detached.

[0130] The following describes the cable connections of the panel assembly 30 and the cable arrangement structure of the door body 40 with reference to the drawings.

[0131] Figure 15 is a partial perspective view showing the upper part of the door body. Figure 16 is an exploded perspective view showing the wiring arrangement between the upper end of the door and the top cover.

[0132] As shown in the figure, a hinge mounting portion 432 is recessed at one end of the upper surface of the door 21, and a hinge device for rotatably connecting the door 21 to the cabinet 10 is mounted thereon. The hinge mounting portion 432 may also be formed at one end of the upper cap 43.

[0133] Furthermore, a hinge hole 433 is formed in the hinge mounting portion 432 into which the rotation shaft of the hinge device is inserted. On one side of the hinge hole 433, a wire hole 434 is formed through which the door cable 921 passes.

[0134] The door cable 921 may be equipped with connectors 922 and 923 at both ends. The connector 923 is connected to one end of the door cable 921 that flows out to the outside of the door body 40 via the hinge mounting portion 432, and is easily connected to the cable connected to the control unit 11 of the cabinet 10. In other words, the cable 921 can be separated and connected when the door 21 is separated and installed.

[0135] Furthermore, a connector 922 is provided at the other end of the door cable 921, which can be exposed to a connector opening 402 at the top of the housing space 401 of the door body 40. Therefore, when the panel assembly 30 is installed, the connector 910 on the panel cable 911 of the panel assembly 30 and the connector 922 on the door cable 921 can be connected to each other within the housing space 401. In other words, during the installation process of the panel assembly 30, the cable 911 connected to the panel assembly 30 can be passed directly through the door body 40 and easily connected and disconnected without being connected to the control unit 11 of the cabinet 10.

[0136] On the other hand, a recessed cap space 430 is formed on the upper surface of the upper cap 43, and a cap passage hole 435 is formed inside the cap space 430 through which the cover connecting cable 931 passes. The cap passage hole 435 is opened so that the cap space 430 and the housing space 401 are in communication, and the cover connecting cable 931 can pass through it.

[0137] A connector 932 is provided at one end of the cover connecting cable 931, and the connector 932 is connected to the first PCB assembly 80. The other end of the cover connecting cable 931 extends into the cap space 430, and a connector 933 is provided at the end of the cover connecting cable 931, which is connected to the connector 942 of the cover cable 941 connected to the cap cover 48.

[0138] Meanwhile, foaming liquid inlets 436 are opened on both sides of the upper surface of the upper cap 43. The foaming liquid inlets 436 are opened at both ends of the cap space 430, and foaming liquid is injected into the interior of the door body 40.

[0139] The cap cover 48 is then attached to the upper surface of the upper cap 43. The cap cover 48 can shield the cap space 430 and form part of the upper surface of the upper cap 43, that is, part of the upper surface of the door 21.

[0140] Numerous upper restraint protrusions 483, which are inserted into the upper restraint groove 802, may be formed on the lower surface of the cap cover 48. Cover fastening holes 484 are formed on both sides of the cap cover 48, through which fastening members for fixing the cap cover 48 to the upper cap 43 are fastened.

[0141] On the other hand, the cap cover 48 may be equipped with a microphone 482 for receiving user voice commands and a speaker 481 for outputting sound. The microphone 482 and the speaker 481 are fixedly mounted on the lower surface of the cap cover 48 and connected to the cover cable 941. A connector 942 may be provided at the end of the cover cable 941. Therefore, when the cap cover 48 is attached to the upper cap 43, the connector 942 of the cover cable 941 and the connector 933 of the cover connecting cable 931 can be connected to each other.

[0142] Furthermore, the cap cover 48 has a microphone hole opening at a position corresponding to the microphone 482 so that the user's voice is transmitted to the microphone 482. The cap cover 48 may also be provided with a speaker cover 485 that shields the speaker 481 from above.

[0143] In the following section, the operation of the refrigerator 1 according to an embodiment of the present invention having the structure described above will be explained in detail with reference to the drawings.

[0144] Figure 17 is a block diagram showing the flow of the control signals for the refrigerator. Figure 18 is a diagram showing the door display in the ON and OFF states.

[0145] As shown in the figure, in the refrigerator 1 according to an embodiment of the present invention, the state of the display window 312 can change in various ways in accordance with the operation of the display 33.

[0146] The operation of the door light 111, speaker 481, and heater 47, including the display 33, is controlled by the control unit 11. The control unit 11 can control the operation of the refrigerator 1 in response to user operation recognition by the touch sensor 32, user approach or operation detection by the sensing device 112, and recognition of user voice command input by the microphone 482. The sensing device 112 can be a knock detection device, proximity detection device, illuminance sensor, etc.

[0147] For example, when the display 33 is off and the display panel 32 is not operating, the display window 312 becomes opaque, the space behind the door 21 becomes dark, and the space behind the door 21 is no longer visible through the display window. At this time, the lighting device 111 may also be off.

[0148] When the user touches the display window 312, the touch sensor detects the touch and the display 33 can be turned on. When the display 33 is turned on, the screen output from the display 33 is displayed through the display window 312, as shown in Figure 18(a), and the user can see it. When the lighting device 111 is turned off, the space behind the door 21 becomes invisible through the display window 312.

[0149] When a user touches the display window 312, the touch sensor 32 detects the touch and turns on the lighting device 111. When the lighting device 111 is turned on, the space behind the door 21 becomes brighter, as shown in Figure 18(b), and the display window 312 can visualize the space behind the door 21.

[0150] On the other hand, when both the display 33 and the lighting device 111 are turned on, the space behind the door 21 can be seen through the display window 312, and the display 33 can simultaneously output a screen. In other words, the display window 312 can output a screen on the transparent display 33 while the space behind the door 21 is visible.

[0151] The operation of the display 33 and the lighting device 111 can be controlled not only by the operation of the touch sensor 32, but also by detection by the sensing device 112, voice input by the speaker 481, and via other operating devices or remote devices provided in the refrigerator.

[0152] The display window 312 can provide users with a variety of usage environments by utilizing these diverse screen output states. Below, examples of changes in the state of the display window will be explained with reference to the drawings.

[0153] Figure 19 is a diagram showing an example of the change in state of the indicator window on the door. As shown in the diagram, the refrigerator 1 can change from one screen state to another in response to user operation.

[0154] More specifically, as shown in Figure 19(a), the display 33 can operate to output a specific screen. For example, the display 33 outputs a specific screen until a specific operation is input, at which time the lighting device 111 is turned off and the screen output from the display 33 is visible in the display window 312 while the space inside the refrigerator is not visible. For example, the specific screen may display images of falling snow and buildings.

[0155] Then, when the user touches or knocks on the display window 312, the output screen of the display 33 can change as shown in Figures 19(b) and (c). For example, the size of the building may be reduced and displayed as a small snowball shape at the bottom of the display window 312. At this time, the lighting device 111 can be turned on, and when the lighting device 111 is turned on, the space behind the door 21 becomes visible through the display window 312.

[0156] Then, as shown in Figure 19(c), when the user touches or knocks on the display window 312 again while the space behind the door 21 is visible through the display window 312, the lighting device 111 turns off, as shown in Figure 19(d), and the building, which is displayed as a small snowball shape at the bottom of the display window 312, gradually gets bigger until it reaches the state shown in Figure 19(a).

[0157] In this way, the display window 312 changes its screen output state according to user operation, making it possible to visualize the space behind the door 21.

[0158] Figure 20 is a diagram illustrating another example of the state change of the display window. As shown in the diagram, the refrigerator 1 can acquire recipe information based on the stored ingredients via the display window 312 and play music while adjusting the temperature of the refrigerator 1.

[0159] More specifically, as shown in Figure 20(a), the lighting device 111 is turned on in the display window 312 to visualize the space behind the door 21, and at the same time, the display 33 is turned on to display a screen that outputs a recipe selection menu. In other words, a screen is displayed that allows users to select a recipe while checking the stored food behind the door 21 through the display window 312.

[0160] At this time, the control unit 11 of the refrigerator 1 recognizes the food stored in the storage space and can analyze data based on the information of the recognized food. Based on the analyzed data, it can output an appropriate recipe through the display window 312 as shown in Figures 20(b), (c), and (d).

[0161] In more detail, as shown in Figure 20(a), when the user touches the recipe selection menu displayed via the display window 312, the control unit 11 outputs multiple recipes based on the analyzed data. The user then selects one of the multiple recipes by scrolling or swiping on the display window 312, as shown in Figures 20(b) and (c).

[0162] When a user selects a specific recipe, the recipe screen is fixed and displayed in the display window 312, as shown in Figure 20(d). At this time, the user can adjust the size and move the displayed recipe screen to visually confirm the ingredients in the space behind the door 21.

[0163] Once the selection of a specific recipe is completed via touch operation on the display window 312, the display window 312 can display the entire storage space of the refrigerator 1 via the output of the display 33, as shown in Figure 20(e), and can display the temperature of each storage space. The control unit 11 can then adjust the temperature of each storage space to match the optimal temperature of the ingredients required by the selected recipe. It can also adjust the temperature so that the beverages and desserts paired with the dishes prepared according to the selected recipe are stored at the appropriate temperature.

[0164] On the other hand, the desired music and screen can also be output through the display window 312. For example, appropriate music can be output through the speaker 481 along with the cooked food. Therefore, as shown in Figure 20(f), the display window 312 can output a menu screen. In this case, since it is not necessary to check the space behind the door 21, the lighting device 111 may be turned off.

[0165] When a user selects a specific piece of music or a music list through the menu screen, the speaker 481 will output the music. Then, as shown in Figure 20(g), the display 33 can output a screen selected according to the music, thereby allowing a screen for creating atmosphere to be displayed via the display window 312.

[0166] On the other hand, the present invention can be implemented in a variety of other embodiments besides those described above. Other embodiments of the present invention differ only in a part of the door body structure, with the rest of the structure being identical. Therefore, components identical to those in the described embodiments are denoted by the same reference numerals in the drawings, and their detailed descriptions and illustrations can be omitted. Components that are not shown or have been omitted can be referenced from the configurations of the described embodiments. Figure 21 is a cross-sectional view of a door according to another embodiment of the present invention.

[0167] As illustrated, the door 21' of a refrigerator 1 according to another embodiment of the present invention may include a panel assembly 30 and a door body 40. The structure of the panel assembly 30 and the remaining structure of the door body 40, excluding the body panel assembly 50' and the front frame 41', are the same as those of the previously described embodiment. Therefore, reference numerals not described in the drawings may refer to those of the previously described embodiment.

[0168] The body panel assembly 50' may include a first panel 51, a second panel 52, and a third panel 53'. In this case, the first panel 51, the second panel 52, and the third panel 53' may be formed to the same size. A first spacer 541 can be provided between the first panel 51 and the second panel 52 to form the first insulation layer 501. A second spacer 542 can be provided between the second panel 52 and the third panel 53' to form the second insulation layer 502. A sealant 55 may be applied around the body panel assembly 50'.

[0169] On the other hand, the rear surface of the body panel assembly 50', i.e., the third panel 53', can contact the end of the door liner 42 and shield the liner opening 421. The front surface of the body panel assembly 50' can contact the display 33 of the panel assembly 30.

[0170] The door body 40 has insulation material 400 filled into the space where the front frame 41', door liner, side frame 45, upper cap, and lower cap 44 are joined. The body panel assembly 50' is then fitted so as to shield the front frame 41' and the central opening of the door liner 42.

[0171] On the other hand, the front frame 41' forms the front surface of the door body 40 and is positioned around the body panel assembly 50'. The front frame 41' can also form a recessed storage space 401 to accommodate the rear surface configuration of the panel assembly 30.

[0172] In particular, the side protrusions 343 and 634 on both sides of the front panel 31 are inserted into the side restraint grooves 413 of the front frame 41'. Thus, the panel assembly 30 is firmly fixed to the door body 40.

[0173] The front frame 41' may be formed in a rectangular frame shape, and the outer circumference of the front frame 41' is connected to the side frame 45, the upper cap 43, and the lower cap 44. The frame opening 411 is formed inside the front frame 41', allowing the body panel assembly 50' to pass through.

[0174] More specifically, the front frame 41' may include a frame side portion 414. The frame side portion 414 is coupled with the side frame 45 and bent to form a structure that can support the rear surface of the front panel 31.

[0175] The front frame 41' may include a frame housing portion 410' that forms the housing space 401. The frame housing portion 410' may be bent multiple times. The frame housing portion 410' can form a multi-stage recessed space in the housing space 401. For example, the frame housing portion 410' may include a first part 415' that extends rearward and a second part 416' that extends from the first part 415' to the surrounding surface of the body panel assembly 50'. The second part 416' can form a surface facing the rear surface of the front panel 31. The second part 416' has a side restraint portion 412 that protrudes forward.

[0176] The second part 416' can be in contact with the body panel assembly 50' and can form the frame opening 411. Therefore, the body panel assembly 50' is mounted so as to shield the frame opening 411. The inner surface of the second part 416' can be in contact with the body panel assembly 50' and may be joined to each other by adhesive or fastening members.

[0177] The frame housing portion 410' may include a third part 417' that extends rearward from the end of the second part 416', and the third part 417' extends further rearward from the third panel 53'.

[0178] Furthermore, a heater mounting portion 419' is formed at the extended end of the third part 417', in contact with the end of the third panel 53'. The heater mounting portion 419' may be recessed to accommodate the heater 47. Thus, with the heater 47 mounted in the heater mounting portion 419', the heater 47 can contact the periphery of the third panel 53'. At this time, the positions of the heater 47 and the heater mounting portion 419' may be on the rear surface of the third panel 53' or the periphery surface of the third panel 53'.

[0179] Therefore, the body panel assembly 50' is heated by the operation of the heater 47. This allows cold air to be transmitted into the interior of the housing space 401, preventing condensation from occurring.
