The light emitting member 84 may be disposed at a position facing the reflective surface 821a of the depression 821, and may radiate light toward the reflective surface 821a. Accordingly, the light passing through the light cover 83 becomes light reflected from the reflective surface 821a so that the interior light 80 may emit light in the form of surface light.

The light emitting member 84 may be disposed in a direction crossing the light guide plate 64. That is, the light emitting member 84 may be positioned to be rearward with respect to the light guide plate 64 and may be disposed to face the rear side. Therefore, most of the light emitted from the light emitting member 84 is directed to the rear of the light guide plate 64, and the light directed to the light guide plate 64 can be minimized. In addition, the light irradiated directly toward the light guide plate 64 may be shielded by the shield 814.

That is, the support member 662 may be adhered to the first spacer 63 and the second spacer 66, but may be in simple contact with the light guide plate 64 or in a state in which pressure is supported.

The light guide plate 64 may be expanded or contracted by the light irradiated from the display light 68 and heat generated during the operation of the display 62. Accordingly, the light guide plate 64 may correspond to the bending or deformation of the light guide plate 64. In order to maintain the support state, the first spacer 63 and the second spacer 66 support the light guide plate 64 in a simple support state through the support member 662 instead of being bonded.

In the exemplary embodiment of the present invention, the spacers 63, 66, and 67 have different structures, but the spacers 63, 66, and 67 are supported to maintain the gap between the neighboring panels 61, 65 or the light guide plate 64. Various forms may be possible, such as a form or a shape containing an absorbent material therein.

In addition, a heat insulation panel 69 and a light guide plate 64 are provided between the front panel 61 and the rear panel 65. In this case, the heat insulation panel 69 and the light guide plate 64 are the front panel 61. It may be provided alone or together as a plate-like member provided between the rear panel 65 and may be referred to as an intermediate panel. At least one intermediate panel may be provided, and the intermediate panel may not be provided between the front panel 61 and the rear panel 65 if a transparent part capable of seeing the inside may be formed.

The interval between the front panel 61 and the light guide plate 64 maintains a fixed interval for outputting the screen of the display 62. The gap between the light guide plate 64 and the rear panel 65 may be determined according to the thickness of the sub door 50 or the overall thickness of the panel assembly 60. That is, the overall thickness of the panel assembly 60 may be determined by adjusting the thickness of the second spacer 66 to be mounted in accordance with the specification of the sub door 50.

Meanwhile, the rear panel 65 may be disposed at a position adjacent to the door light 57, and the distance between the display 62 and the door light 57 according to the position of the rear panel 65. Can be determined. The space behind the panel assembly 60 may be brightened by the door light 57, thereby making it possible to visualize the storage space.

In the state in which the rear panel 65 is attached to the second spacer 66, an outer end of the rear panel 65 may extend outwardly than the second spacer 66. In addition, the outer spacers 67 are mounted at the outer ends of the rear panel 65 such that the rear panel 65 and the front panel 61 may be fixed to each other.

The outer spacer 67 may be formed in a rectangular frame shape, and the outer spacer 67 may connect the rear surface of the front panel 61 and the front surface of the rear panel 65 and at the same time the panel assembly ( 60) can be formed.

In detail, the outer spacer 67 forms a circumference of the outer portion of the panel assembly 60, and at the same time, the front panel 61 is connected to maintain a predetermined distance.

By the coupling of the outer spacer 67, a space between the front panel 61 and the rear panel 65, that is, an inner space of the outer spacer may be completely sealed. In addition, the inside of the outer spacer 67 may be further sealed by the sealant 608 applied around the outer spacer 67.

The display 62 and the light guide plate 64 may be spaced apart in the front-rear direction in the space sealed by the outer spacer 67, and the first spacer 63 may maintain the gap of the light guide plate 64. The second spacer 66 may also be provided in the inner space of the outer spacer 67.

Of course, an additional heat insulation panel 69 may be further provided inside the outer spacer 67 or a multilayer glass structure may be further provided, and all of these configurations may be provided in a space formed by the outer spacer 67. Can be provided.

That is, the overall appearance of the panel assembly 60 is formed by the front panel 61, the rear panel 65 and the outer spacer 67, and all other components are provided inside the outer spacer 67. It becomes possible. Therefore, sealing only between the outer spacer 67 and the front panel 61 and the rear panel 65 makes it possible to completely seal the multilayer panel structure.

In particular, even when the plate-like structure including the light guide plate 64 is further provided inside the outer spacer 67, only the outermost outer spacer 67 is adhered to the front panel 61 and the rear panel 65. In this case, the airtight structure of the panel assembly 60 may be completed. This hermetic structure can maintain a minimum sealing point even in a multilayer structure by a plurality of panels including the light guide plate 64.

Therefore, it is possible to minimize the likelihood that outside air flows into the panel assembly or condensation inside by moisture permeation. In addition, when vacuuming the inside of the outer spacer 67 or injecting gas for heat insulation, the heat insulation layer may be formed on the entire multilayer structure inside the panel assembly 60, thereby further improving heat insulation performance. have.

As a result, the panel assembly 60 is disposed inside the sub-door 50 to allow perspective and screen output in the refrigerator, and the insulation structure can be completed in a multilayer panel structure with a minimum sealing point. Can be secured.

In addition, a heat insulation panel is provided in an area between the front panel 61 and the rear panel 65 which are hermetically sealed by the outer spacer 67, and the heat insulation panel 69 is provided with the rear panel 65 and the second. The spacer 66 may be spaced apart in an airtight state to form a vacuum heat insulating layer.

Therefore, primary heat insulation is possible by the airtight structure by the said outer spacer 67, the front panel 61, and the rear panel 65, and the 2nd spacer 66, the heat insulation panel 69, and the rear panel 65 are possible. Finally, the panel assembly 60 may have a double insulation structure, and the insulation property of the entire panel assembly 60 may be greatly improved to effectively insulate the inner side of the panel assembly 60. It becomes possible.

 The inner surface of the outer spacer 67 may provide a space in which the display light 68 may be mounted. Display lights 68 may be mounted on upper and lower ends of the outer spacer 67, and the light guide plate 64 may be disposed between the display lights 68 disposed on the upper and lower ends of the outer spacer 67. Can be located.

Therefore, the light irradiated through the display light 68 may be directed toward the end of the light guide plate 64, and may be moved along the light guide plate 64 to cause the light guide plate 64 to emit light from the entire surface. .

Meanwhile, the display light 68 positioned at the inner upper and lower ends of the panel assembly 60 may be connected to the display light cable 606. The display light cable 606 may be formed in a flexible and flat shape like the touch cable 601 and the display cable 605.

The display light cable 606 may be connected to the display light 68 mounted on the inner side of the outer spacer 67 and may extend to the outside of the panel assembly 60.

In addition, the display light cable 606 may extend along the circumference of the transparent display 62 so as not to be exposed through the transparent display 62. In addition, the display light cable 606 may extend upward in close contact with the rear surface of the rear panel 65, and may be bent in a state of being bonded to the rear panel 65 when necessary to the sub-door. 50 may be connected to the docking PCB 604 above.

In this case, since the display light cable 606 extends in close contact with the circumferential surface of the rear protrusion 651 of the rear panel 65, through the panel assembly 60 when viewed from the outside of the sub door 50. It will not be exposed.

The sealant 608 may be coated around the outer spacer 67. The sealant 608 may be applied to form a circumferential surface of the panel assembly 60, and form a circumferential surface between the front panel 61 and the rear panel 65.

The sealant 608 is sealed to prevent the inflow of air into the panel assembly 60, and may be formed of a polysulfide material. Of course, if necessary, it may also be formed of other sealant materials such as silicone and urethane, which may be in direct contact with the foaming liquid injected to mold the insulation 531.

The outer spacer 67 and the front panel 61 and the rear panel 65 can be held together by the sealant 608 and at the same time, the sealing part of each component is completely sealed to allow the inflow of moisture or moisture. It can be prevented. In addition, the sealant 608 may protect the circumference of the panel assembly 60 to a portion in which the foaming liquid directly contacts when forming the heat insulating material 531.

The sealant 608 allows cables 601, 605, and 606 connected to the touch sensor 612, the display panel 62, and the display light 68 to enter and exit the panel assembly 60. That is, the sealant 608 blocks the outer surface of the cable 601, 605, 606 when the cables 601, 605, 606 extend outwards through the circumferential surface of the panel assembly 60, so that water or space into the space into which the cables 601, 605, 606 enters and exits. It can block the ingress of moisture.

In addition, a heater mounting unit 673 on which a spacer protrusion 672 and a heater 532 are mounted, are mounted on a circumferential surface of the panel assembly 60 to which the sealant 608 is applied, forming a space in which the sealant 608 is filled. May be formed to protrude, and the sealant 608 may be filled in a space between the spacer protrusion 672 and the heater mounting part 673. More detailed structures of the spacer protrusion 672 and the heater mounting portion 673 will be described later.

14 is a partial perspective view showing an arrangement state of a display cable of the panel assembly.

As shown in the figure, the display cable 605 is connected to the source board 621 and extends upward, and extends along the side circumference of the panel assembly 60 and is then connected to the ticon board 602. Can be.

The display cable 605 may be connected to the source board 621 inside the panel assembly 60, and may be connected to the outer spacer 67 through the rear panel 65 and the outer spacer 67. It may be guided out of.

In detail, a cable connection part 605a may be formed in the display cable 605. The cable connection part 605a may be introduced into the panel assembly 60 into a space formed between the rear panel 65 and an end of the outer spacer 67, and may be inside the transparent display 62. It may be connected to the source board 621 in the space.

The cable connection part 605a is guided to the outer surface of the panel assembly 60 through a gap between the seal member 671 and the sealant 608 that bonds the rear panel 65 to the outer spacer 67. Can be. Thus, the display cable 605 may be guided outward so as to pass around the hermetically sealed panel assembly 60.

The adhesive member 671 may also be provided between the front panel 61 and the end of the outer spacer 67. The adhesive member 671 may be thinly formed so that heat generated from the outer spacer 67 may be sufficiently transmitted to the front panel 61. Of course, the outer spacer 67 may not be bonded by the front panel 61 and the adhesive member 671, but may be coupled in other ways. In this case, the outer spacer 67 may be directly connected to the front panel 61. It may have a structure capable of contacting heat transfer.

In this state, the display cable 605 may be bent upwardly in contact with the outer surface of the panel assembly 60 to which the sealant is applied, and may be bent again to be connected to the Ticon board 602. Can be. That is, the display cable 605 may be extended to be connected to the Ticon board 602 in a state of being exposed to the outside of the panel assembly 60.

In addition, the sealant 608 may be exposed to the outer surface of the panel assembly 60, and the spacer protrusion 672 and the heater mounting part 673 may be exposed between the sealant 608. It can be configured to be. Accordingly, the panel assembly 60 may be mounted to the door 50 in the assembled state, and the panel assembly 60 may be fixed to the door 50 in the mounted state. The heater 532 may be mounted or connected to the heater 532 mounted thereon.

15 is a cross-sectional view of the top of the panel assembly.

As shown in the figure, the sealant 608 may be applied to the outermost circumferential surface of the panel assembly 60. The sealant 608 may be applied between the front panel 61 and the rear panel 65 and may be configured to cover the outer side of the outer spacer 67.

The panel assembly 60 may be mounted to the door 50 in a state where the sealant 608 is coated, and have a structure supported by the support frame 70. Accordingly, when the sealant 608 does not have a uniform surface, it may be misassembled or defective due to interference with the support frame 70 or other neighboring components when the panel assembly 60 is assembled. there is a problem.

In particular, in the case where the distance between the front panel 61 and the rear panel 65 is far, the work of uniformly applying the sealant 608 is not easy, and the surface having irregularities in one side or a local section This may be formed.

In order to prevent such a problem, a spacer protrusion 672 and the heater mounting part 673 may be formed on the outer surface of the outer spacer 67. The spacer protrusion 672 and the heater mounting part 673 may be disposed side by side at positions apart from each other, and may protrude to the same height. The sealant 608 may be filled to a uniform height in a space between the front panel 61, the rear panel 65, the spacer protrusion 672, and the heater mounting part 673.

After application of the sealant 608, the outer surface of the spacer protrusion 672 may be exposed to the circumferential surface of the panel assembly 60. In addition, a plurality of fastening holes 672a may be formed on the exposed outer surface of the spacer protrusion 672. A coupling member such as a screw that is fastened for coupling with the panel assembly 60 is fastened to the fastening hole 672a.

In addition, a heater groove 673a may be formed on an outer surface of the heater mounting unit 673 in which the heater 532 is inserted and mounted from the outside. In addition, the heater groove 673a is formed to be exposed to the outside, so that the heater 532 is provided in the heater groove 673a in the exposed state while the panel assembly 60 is mounted to the door 50. I can attach it.

The outer spacer 67 may be formed of a metal material, and in particular, may be formed of an aluminum material having excellent heat transfer performance. Accordingly, when the heater 532 generates heat, heat transfer may be performed to the front panel 61 through the outer spacers 67. Therefore, condensation may be prevented from occurring on the front surface of the front panel 61.

The light guide plate 64 may be spaced apart from the rear of the display 62 and positioned at a position corresponding to the display light 68. The display light 68 is positioned above and below the light guide plate 64, and allows light to be irradiated to an end of the light guide plate 64.

The display light 68 includes a plurality of substrates 681 fixed to the outer spacers 67 and a plurality of LEDs 682 disposed on the substrate 681 and disposed at regular intervals along the light guide plate 64. It may include. Since the display light 68 illuminates the display 62 at the rear of the display 62, the display light 68 may be generally referred to as a backlight, and various structures capable of irradiating light toward the end of the light guide plate 64 may be possible. have.

The light guide plate 64 is configured to allow light incident to the end of the light guide plate 64 to be evenly guided to the entire surface of the light guide plate 64 and to be irradiated toward the entire surface of the display 62 in front of the light guide plate 64. The light guide plate may be injection-molded with a transparent plastic material such as acrylic (PMMA), and is formed to be transparent so that perspective through the light guide plate 64 may be achieved. The light guide plate 64 may provide sufficient brightness so that the display 62 may be clearly output, and may have uniform brightness in the entire area, while maintaining the appropriate transparency of 4 mm to 10 mm. It may be formed in a thickness.

Unlike the general structure of the backlight of the display panel, the light guide plate 64 should be able to see through the rear region of the light guide plate 64. Therefore, the light guide plate 64 may have transparency of the light guide plate like a separate reflective sheet or pattern. Configurations that may be degraded are not placed.

However, in the structure that is not disposed on the reflective sheet or the pattern so that the light through the light guide plate 64 can be viewed, even brightness is hardly realized on the entire surface of the light guide plate 64, and the shadow is farther than the portion close to the display light 68. Can be generated. Due to the shading of the light guide plate 64, there may be a problem that shading occurs on the screen output from the display 62.

Therefore, in the present exemplary embodiment, when the light diffusing agent 643 is added to the light guide plate 64 and the light is irradiated to the light guide plate 64 without a reflective layer or pattern in the general light guide plate, the entire light guide plate 64 is evenly brightened. It is configured to be.

16 is a diagram illustrating an example of a light guide plate constituting the transparent panel.

Referring to the drawing, a light scatterer may be added to the light guide plate 64 so that light introduced into the light guide plate 64 may reach the light diffuser 643. The light guide plate 64 has an even brightness over the entire area by the light diffusing agent 643 evenly distributed over the entire area of the light guide plate 64 so that the display 62 does not appear shaded and is seen with even brightness. can do.

That is, the light diffusing agent 643 may solve the problem of realizing uniform brightness of the entire light guide plate 64 generated while the light guide plate 64 is configured to be clearly visible.

The light diffusing agent 643 may be added to acrylic, which is a main material of the light guide plate 64 when the light guide plate 64 is formed, and thus may be evenly distributed over the entire area of the light guide plate 64. In addition, the light diffusing agent 643 is capable of scattering light such as silica (silicon dioxide), titanium dioxide, alumina (aluminum oxide), acrylic resin, polycarbonate resin, silicone resin, and the like, and particles of transparent materials may be used. .

The light guide plate 64 should be able to maintain a transparent state when the display light 68 is not turned on. Therefore, the light diffusing agent 643 may have a size of several micrometers or less, preferably nano size. The light guide plate 64 may be evenly distributed throughout the inside of the light guide plate 64.

Through this structure, when the display 62 is operated and the display light 68 is turned on, the entire light guide plate 64 shines with uniform brightness, and the display 62 displays the entire screen bright. You can see clearly.

On the other hand, when the user wants to see and view the storage space of the high inside, the display 62 and the display light 68 are turned off, and the inside light 80 or the door light 57 is turned on and the high inside This can be made visible.

In this case, when the light emitted from the interior light 80 or the door light 57 is directed toward the light guide plate 64, the light guide plate 64 is remarkably transparent due to scattering of light due to the light diffusing agent 643. Falling problems can occur. therefore. The interior light 80 or the door light 57 should not directly irradiate light toward the light guide plate 64, and this structure will be described in detail below.

17 and 18 are views illustrating an apparatus for manufacturing the light guide plate.

17 and 18, in the manufacturing apparatus 1000 of the light guide plate 64, a first reservoir 1010 and an optical diffusing agent 643 in which acrylic monomers, which are main materials of the light guide plate 64, are stored. It includes a second reservoir 1020 is stored. The acrol monomer may be stored in the liquid phase in the first reservoir 1010, and the light diffusing agent 643 may be stored in the second reservoir 1020 as a powder.

The light diffusing agent 643 may be formed of at least one material of calcium carbonate (CaCO 3) and titanium dioxide (TiO 2). In addition, the particle size of the light diffusing agent 643 may be formed to 70μm ~ 100μm. If the particle size of the light diffusing agent 643 is formed to be larger than 100 μm, sparking may occur to prevent mixing with the acrylic monomer.

The manufacturing apparatus 1000, a first supply line 1031 extending from the first reservoir 1010 to the agitator 1040 and a second supply extending from the second reservoir 1020 to the agitator 1040. Line 1035 is included.

The acrylic monomer may be supplied to the stirrer 1040 through the first supply line 1031, and the light diffusing agent 643 may be supplied to the stirrer 1040 through the second supply line 1035. have. The light diffusing agent 643 may be dispersed in the acrylic monomer.

The weight ratio of the light diffusing agent 643 based on the weight of the entire material of the acrylic monomer and the light diffusing agent 643 may be formed within a range of about 0.1 to 0.5%.

The stirrer 1040 is provided with an impeller 1042, and the acrylic monomer in which the light diffusing agent 643 is dispersed by the operation of the impeller 1042 may be mixed. Thus, the light diffusing agent 643 may be evenly distributed in the acrylic monomer. At this time, the temperature condition for stirring in the stirrer 1040 is room temperature (about 25 ℃), the number of revolutions of the impeller 1042 may be formed of 60 ~ 120RPM.

The material mixed in the stirrer 1040, ie, the acrylic monomer and the light diffusing agent 643, is moved to the injection device 1050 through the third supply line 1045, and the injection device 1050 plate the material. Inject into the assembly 1060.

The plate assembly 1060 includes an upper plate 1061 and a lower plate 1063, and a spacer 1065 spaced apart from the upper plate 1061 and the lower plate 1063.

The upper plate 1061 and the lower plate 1063 include a glass plate. Since the upper and lower plates 1061 and 1063 constituting the frame of the glass are made of glass, the surface of the light guide plate to be manufactured can be smoothed, and the glass is made of light weight, which increases manufacturing convenience and can be inexpensive.

An injection hole 1062 may be formed in the upper plate 1061 to inject the material.

The spacer 1065 may be placed on an edge of the lower plate 1063 and extend upward, and the upper plate 1061 may be seated on an upper side of the spacer 1065. By the spacer 1065, the lower plate 1063, and the upper plate 1061, an inner space in which the material may be positioned may be formed in the plate assembly 1060.

The thickness of the light guide plate 64 to be manufactured may be determined by the amount of material injected from the injection device 1050.

Meanwhile, the plate assembly 1060 may be placed on the roller 1070 to move in the direction in which the roller 1070 rotates. In detail, when the injection of the material to the one plate assembly 1060 positioned adjacent to the injection device 1050 is completed, the one plate assembly 1060 is moved and the other plate assembly 1060 is adjacent to the injection device 1050 The material can be injected by moving to a position.

Through the injection device 1050, the plate assembly 1060 in which the injection of the material is completed may be introduced into the curing tank 1080. For example, the curing tank 1080 may include a water tank in which water (W) is stored.

A plurality of plate assemblies 1060 may be stacked and disposed in the curing bath 1080. A plurality of support plates 1085 may be provided in the curing tank 1080, and the plate assembly 1060 may be placed on the support plate 1085.

The temperature of the water (W) stored in the curing tank 1080 forms about 50 ~ 60 ℃. The material injected into the plate assembly 1060 is cured by reacting with the water, and the curing time is about 5 hours. Then, the cured material may be separated from the upper plate 1061 and the lower plate 1063 after heat treatment to be manufactured as a light guide plate.

Another embodiment is proposed.

In the manufacturing apparatus 1000, the upper plate and the lower plate constituting the plate assembly has been described as consisting of a glass plate, alternatively, the upper plate and the lower plate may be composed of a metal plate. In one example, the metal plate may be made of steel, copper or aluminum.

19 is a view illustrating another example of the apparatus for manufacturing the light guide plate.

Referring to FIG. 19, the light guide plate manufacturing apparatus 1000a includes a curing tank 1080a provided with a UV lamp 1090. A plurality of plate assemblies 1060 having materials injected from the injection device 1050 described with reference to FIG. 17 may be stacked and disposed in the curing bath 1080a. The plate assembly 1060 may be supported by the support plate 1085.

The UV lamp 1090 may be disposed on an inner side surface of the curing tank 1080a to irradiate UV toward the plate assembly 1060. In this process, the material injected into the plate assembly 1060 may be cured.

For example, the plurality of UV lamps 1090 is provided, the plurality of UV lamps 1090 are arranged on both sides of the curing tank (1080a) in the vertical direction, the plate located in the center of the curing tank (1080a) UV may be irradiated toward the assembly 1060.

Since the upper plate 1061 and the lower plate 1063 constituting the plate assembly 1060 are composed of glass plates, ultraviolet rays irradiated from the UV lamp 1090 may pass through the glass plate to easily cure the material. Can be.

20 is a flowchart illustrating a method of manufacturing the light guide plate.

17 to 20, the acrylic monomer stored in the first reservoir 1010 and the light diffuser 643 stored in the second reservoir 102 are supplied to the stirrer 1040, and the light diffuser ( 643) may be dispersed in the acrylic monomer (S11).

The material supplied to the stirrer 1040, that is, the acrylic monomer and the light diffusing agent 643 may be evenly mixed by the action of the impeller 1042 provided in the stirrer 1040. In addition, the mixed material may be supplied to the plate assembly 1060. The material may be filled in the inner space formed by the upper plate 1061, the lower plate 1063, and the spacer 1065 (S12).

When the material is filled in the plate assembly 1060, the plate assembly 1060 may be put into the curing bath. For example, the plate assembly 1060 may be added to the water tank 1080 shown in FIG. 18, and the curing process may be performed by water stored in the water tank 1080.

As another example, the plate assembly 1060 may be added to the curing bath 1080a shown in FIG. 19, and the curing process may be performed by the UV lamp 1090 provided in the curing bath 1080a. (S13).

When the curing process is performed, a heat treatment process may be performed on the plate assembly 1060. The heat treatment temperature is about 110 ° C., and the heat treatment time may be about 2 hours. By the heat treatment process, the residual stress present in the cured material can be reduced (S14).

After performing the heat treatment process, a cooling process may be performed. The cooling process may be performed by a natural cooling method at room temperature, the cooling time may be about 2 hours (S15).

After performing the cooling process, the upper and lower plates 161 and 153 and the spacers 165 are separated from the plate assembly 106, and thus the material may be obtained as the light guide plate 64 (S16).

A protective film may be attached to the light guide plate 64, and cutting may be performed according to a required size (S17 and S18).

In addition, a polishing process for smoothing the surface of the light guide plate 64 may be performed, and a process of inspecting for defects may be performed. By such a process, the light guide plate 64 in which the light diffusing agent 643 is evenly distributed can be easily manufactured (S19, S20).

Meanwhile, another example of the light guide plate may be applied to the refrigerator according to the embodiment of the present invention.

21 is a diagram illustrating another example of the light guide plate.

As illustrated, the light guide plate 64 may have a structure in which a diffusion layer 642 including the light diffusing agent 643 is formed on the surface of the resin layer 641.

The light guide plate 64 may be injection-molded with a transparent plastic material such as acrylic (PMMA), and may be transparently formed so that perspective through the light guide plate 64 may be achieved.

In addition, a diffusion layer 642 may be formed on the front surface of the display 62. The diffusion layer 642 is formed by coating a coating material including the light diffusing agent 643 on the entire surface of the resin layer 641, or is formed in a film shape including the light diffusing agent 643. It may be formed to adhere to the front of the 641.

Meanwhile, the diffusion layer 642 including the light diffusing agent 643 may be provided in a form in which the resin layer 641 is completely adhered, fused, or applied. In this case, the diffusion layer 642 and the resin layer 641 may be provided. ) May have a structure in which bubbles are not generated at the interface and completely contact each other.

Therefore, the light directed from the resin layer 641 to the diffusion layer 642 can be prevented from refracting in the air layer at the interface. That is, light moving along the resin layer 641 passes through the resin layer 641 and is directed toward the diffusion layer 642 without changing the angle so that loss due to refraction does not occur.

In addition, the resin layer and the diffusion layer have a structure that is completely in contact with each other so that no layer is seen when viewed from the front, and thus the transparency of the light guide plate 64 is not lowered. On the other hand, if a fine air layer or gap is generated between the resin layer 641 and the diffusion layer 642 so as not to be in close contact with the interface, it may affect the transparency of the light guide plate 64 itself. There is a problem that the transparency is lowered when seeing through the inner panel through the panel assembly 60.

In general, the structure of a general light guide plate is provided in a form in which a separate sheet for reflection or a separate sheet for diffusion is simply mounted on the surface of the light guide plate due to problems of deformation such as expansion and contraction of the light guide plate. In the embodiment, the diffusion layer 642 is completely adhered to the surface of the resin layer 641 for the same reason as described above, so that no air layer or minute gaps are formed at all.

On the other hand, the diffusion layer 642 is located in front of the resin layer 641 to enable effective light irradiation toward the display 62, as well as the high light provided behind the light guide plate 64. It is possible to minimize the opacity of the light guide plate 64 by the 80 or the door light 57.

In addition, the diffusion layer 642 may be formed to have a thickness of 40 μm to 60 μm.

If the thickness of the diffusion layer 642 is too thin, the entire light guide plate 64 may not be uniformly illuminated, resulting in shading on the light guide plate 64. That is, the thickness of the diffusion layer is 40 μm or less. In the case where the thin film is formed as a thin film, when the light is irradiated onto the light guide plate 64 to illuminate the display 62, the amount of the light diffusing agent 643 distributed in the diffusion layer 642 is relatively small. (64) The entirety cannot be made uniform, thereby degrading the quality of the output screen of the display 62. Therefore, the thickness of the diffusion layer 642 may be formed thicker than at least 42㎛.

In addition, when the thickness of the diffusion layer 642 is too thick, the amount of the light diffusing agent 643 is so large that when the door light 57 illuminating the inner side is turned on, the light guide plate ( 64) there is a problem that the transparency can be reduced. In addition, when the thickness of the diffusion layer 642 is too thick, a volatilization time of the solvent constituting the diffusion layer 642 takes a long time, and cracking occurs during drying or the resin layer 641 during operation of the refrigerator 1. There is a problem of peeling off. In addition, even when the light guide plate 64 shrinks and expands or flexes, when the thickness of the diffusion layer 642 is too thick, the diffusion layer 642 may be peeled off or a space may be generated, thereby causing the performance of the light guide plate 64. This deterioration problem may occur. Therefore, the diffusion layer 642 may be molded to a thickness of 60 μm to prevent peeling or cracking of the diffusion layer 642 while ensuring the appropriate amount of light.

Meanwhile, a light diffusing agent 643 may be included in the resin layer 641 as well as the diffusion layer 642 within a range in which the transparency of the light guide plate 64 does not decrease, and may be provided in the light guide plate 64. The amount of light that can be maximized.

22 is a schematic block diagram of a flow of a control signal of a display and lights of the refrigerator. 23 is a view schematically showing the lighting state of the door light and the interior light of the refrigerator. 24 is a view schematically showing the arrangement of the display light, the door light, and the interior light. 25 is a cross-sectional view taken along the line 21-21 'of FIG. 20.

As shown in the figure, the refrigerator 1 is the display 62, the display light 68, the interior light 80, the door light (by the control unit 90 when the user operates the operation input unit 92) ( 57, it is possible to control the operation. The control unit 90 may include the control unit 14 described above, or may be provided separately from the control unit 14.

In addition, the manipulation input unit 92 is for a manipulation input of a user, and may include a touch sensor 612 or a separate operable switch, a voice recognition microphone, and various sensors of the panel assembly 60. When the user manipulates the control signal 90, the display 62, the display light 68, the door light 57 and the interior light 80 may be operated.

In order to see the high inside through the panel assembly 60, first, the door light 57 and / or the inside light 80 for manipulating the operation input unit 92 of the user and illuminating the inside of the high according to the user's operation are provided. Can be lit.

That is, when the door light 57 and / or the interior light 80 are turned on and the interior of the interior becomes bright, the interior of the interior is visible through the panel assembly 60. In this case, the rear door light 57 adjacent to the panel assembly 60 may be turned on. In particular, in order to visualize the door-side storage space formed behind the sub-door 50, it may be more effective that the door light 57 is turned on. Of course, when the interior light 80 is turned on, the inside of the refrigerating chamber 12 may be visualized.

On the other hand, the door light 57 may be disposed so as to face rearward at least parallel to the light guide plate 64 provided in the panel assembly 60 or cross the light guide plate 64 in the lit state.

In detail, the door light 57 may reveal a high inner storage space so that the high inner side may be more visible through the panel assembly 60. However, when the light irradiated from the door light 57 or the interior light 80 is directed toward the light guide plate 64, the light guide plate 64 emits light by the light diffusing agent 643 included in the light guide plate 64. This may be made and there is a problem that the transparency of the light guide plate 64 may be lowered. Therefore, the transparency of the light guide plate 64 should be minimized in order to see the inside of the high through the panel assembly 60 better.

To this end, the door light 57 may have an arrangement and structure in which light is not directly irradiated toward the light guide plate 64.

The door light 57 may be provided in the sub door 50 and disposed at the rear of the light guide plate 64 so as to illuminate a door side storage space formed in the refrigerating compartment door.

The door light 57 may be configured to brighten the door side storage space provided in the refrigerating compartment door 20 on the right side without directly irradiating light toward the light guide plate 64. The door lights 57 may be disposed at both sides with respect to the light guide plate 64, and may be disposed to face each other.

At this time, the light irradiated from the door light 57 may be irradiated toward the inner side in the set angle γ range. In this case, the set angle γ may be any angle between an angle parallel to the light guide plate 64 and an angle to the rear of the light guide plate 64. That is, the door light 57 may be disposed to face in a direction parallel to the light guide plate 64, or may be disposed to face a rear surface perpendicular to the light guide plate 64, and to the light guide plate 64. It may be arranged to have any angle between the expanded position and the vertical position.

Since the door light 57 only needs to illuminate the door side storage space provided on the rear surface of the refrigerating compartment door 20 and not inside the refrigerating compartment 12, the door light 57 intensively illuminates a relatively narrow area compared to the interior light 80. It can be configured to be. In addition, the light may be prevented from being directly irradiated toward the light guide plate 64 through the restriction of the irradiation angle, thereby preventing the viewable area from being blurred by the light guide plate 64 in a situation where the user intends to see the inside. .

The interior light is provided on both left and right inner walls of the refrigerating compartment 12 and may be turned on to illuminate the inside of the refrigerating compartment 12.

The interior light 80 may be turned on when the refrigerating compartment door 20 is opened and the door switch 91 detects this. In addition, the interior light 80 may be turned on to visualize the interior of the interior through the see-through section 21 even when the refrigerator compartment door 20 is closed.

Of course, if necessary, both the door light 57 and the interior light 80 may not be provided, and only one of the door light 57 and the interior light 80 may be provided.

As shown in FIG. 23, the interior light 80 may be variously disposed within a range such that the light of the interior light 80 is not directly irradiated to the light guide plate 64 when turned on.

In detail, the interior light 80 may be disposed in parallel with respect to the light guide plate to face the interior of the light guide plate, and may be formed to have a predetermined angle to the rear with respect to the light guide plate 64 as necessary. have. In this case, the first set angle α that the light emitting surface of the interior light 80 forms with the light guide plate 64 may be an angle between about 0 ° and 90 ° so as to effectively illuminate the inside of the high light, about 45 °. The angle of will be appropriate.

Of course, if the interior light 80 is not irradiated directly toward the light guide plate 64 may be disposed to face forward.

That is, the interior light 80 may be disposed to face forward at a set angle with respect to the light guide plate 64. When the angle of the interior light is too large toward the light guide plate 64, light may be directly irradiated toward the light guide plate 64 so that the light of the interior light 80 is not directly irradiated to the light guide plate 64. The light emitting surface of the interior light 80 may be disposed to face the second set angle β with respect to the light guide plate 64.

At this time, it is preferable that the second set angle β of the interior light 80 facing forward is smaller than the first set angle α of the interior light 80 facing backward, and is approximately 30 degrees. Rather, it will be illuminated to the front at a small angle to illuminate the inside of the high.

Meanwhile, the relationship between the display light 68, the door light 57, and the interior light 80 will be described with reference to FIGS. 24 and 25.

As shown, the display light 68 may be provided inside the panel assembly 60, and may be disposed at upper and lower ends of the light guide plate 64. The display light 68 is disposed along a horizontal direction whose length is relatively shorter than that in the vertical direction, but the entire light guide plate 64 may be evenly brightened by the light diffusing agent 643 of the light guide plate 64. In addition, it is possible to provide a screen having no uniform shadow and uniform brightness.

In addition, the door light 57 may be disposed somewhat rearward than the panel assembly 60, and may be configured to illuminate a door side storage space disposed on the rear surface of the door 50.

The door light 57 may be disposed in both the left and right sides of the door 50 in the vertical direction, that is, the light guide plate 64, and may extend from an upper end to a lower end of the panel assembly 60. The door light 57 may be vertically disposed to extend the entire area of the door-side storage space evenly, and may provide brightness that can be sufficiently identified from the inside through the panel assembly 60 from the outside. .

That is, based on the light guide plate 64, the display light 68 is disposed up and down and extends in the horizontal direction, and the door light 57 is disposed at the left and right and extends in the vertical direction.

On the other hand, the door light 57 is preferably disposed at a set distance (D1) corresponding to the rear end of the door 50 in order to effectively light the door-side storage space behind the door 50, this arrangement Through the door side storage space from the outside can be seen well.

In addition, the door light 57 may be disposed to be relatively close to the rear surface of the panel assembly 60, and when the door light 57 is structurally disposed to be inclined forward, the light may be directly irradiated onto the light guide plate 64. high. Therefore, the door light 57 may be disposed to face the light guide plate 64 horizontally or somewhat rearward, thereby minimizing the incident light directly on the light guide plate 64.

On the other hand, the interior light 80 may be disposed more rearward than the door light 57, it will be preferable to be disposed at the set distance (D2) corresponding to one point of the interior. On the other hand, the interior light 80 is relatively far from the light guide plate 64, and in this arrangement the light is irradiated even if the interior light 80 is slightly forward facing the door 50 is disposed The light guide plate 64 may not face directly.

On the other hand, the interior light 80 may further include a rear interior light 80 provided on the rear wall surface of the refrigerating chamber 12. The rear door light 57 may be turned on only when the opening of the refrigerating compartment door 20 is detected by the door switch 91, and the light guide plate may not be turned on when the refrigerating compartment door 20 is closed. Light may not be emitted toward (64).

When the light irradiated from the door light 57 and the interior light 80 is within a set angle, the light irradiated from the door light 57 illuminates the storage space at the side of the sub-door 50 and the light guide plate ( 64, the inner side of the panel assembly 60 is revealed while maintaining the transparency of the panel assembly 60, so that the inner side of the panel assembly 60 may be clearly visible through the see-through part 21.

Hereinafter, a more specific structure of the door light 57 will be described in more detail with reference to the drawings in connection with the operation of the refrigerator 1.

26 is a cross-sectional view of the main door and the sub door. 27 is an enlarged view of a portion A of FIG. 26. 28 is an enlarged view of a portion B of FIG. 26.

As shown in the figure, in the state in which the locking member 593 of the opening device 59 is inserted into the latch hole 421, the sub door 50 is kept closed. The door light 57 is kept off. The open / closed state of the sub door 50 may be detected through a door switch 91 provided separately.

In the state in which the door light 57 is turned off, the rear space of the sub door 50 becomes dark as shown in FIG. 1, so that the inside of the height is not visible through the see-through part 21. Therefore, when there is no operation in the state in which the sub-door 50 is closed, the door light 57 may be kept off so that the inside may not be visible through the see-through part 21.

In this state, the user may touch the front panel 51 or turn on the door light 57 through the manipulation of the manipulation input unit 92. When the door light 57 is turned on, light emitted from the light emitting member 572 may illuminate the rear region of the sub-door 50. When the door light 57 is turned on, the interior of the refrigerating chamber 12 may be turned on. It will be able to reveal, and as shown in Figure 32 or 35 so that the inner side can be visualized through the see-through section 21.

Meanwhile, referring to FIGS. 27 and 28, the structure of the door light 57 will be described in detail. The door light 57 includes a light case 571 in which the light emitting member 572 and the light emitting member 572 are accommodated. And a light cover 573 that shields the light case 571 and transmits light of the light emitting member 572.

In detail, the light case 571 may be provided at both sides of the rear surface of the rear panel 65 and may extend from an upper end to a lower end of the rear panel 65. In addition, the light case 571 may be disposed outside the left and right ends of the see-through part 21, and may illuminate an area behind the panel assembly 60 corresponding to the see-through part 21. .

The light case 571 may be inserted into the door liner 56 protruding on both sides of the rear panel 65. Therefore, the light case 571 may have a structure fixedly mounted by the rear panel 65 and the door liner 56.

One side of the light case 571 may be opened, and an accommodation space 571a may be formed in the light case 571 to accommodate the light emitting member 572. The opening of the light case 571 may be located between the door liner 56 and the rear panel 65 and may be shielded by the light cover 573. Accordingly, the light cover 573 may be exposed while shielding between the rear panel 65 and the ends of the door liner 56, and may be configured to transmit light substantially.

Meanwhile, the front surface of the light case 571 may be formed in a planar shape to contact the rear panel 65. A reflective part 571b may be formed at one end of the light case 571 to be rounded toward an upper end of the light cover 573. The reflector 571b may be formed to have a predetermined curvature, and may reflect light emitted from the light emitting member 572 to pass through the light cover 573. The inner surface of the reflecting portion 571b, that is, the surface facing the inner side of the receiving space 571a of the reflecting portion 571b may be coated with a surface such as coating or deposition to reflect light.

In addition, a shielding portion 571c extending rearward toward the light cover 573 may be formed at one side end at which the opening of the light case 571 is formed. The shield part 571c is to block a part of the light emitted from the light emitting member 572 directly toward the light guide plate 64. The shield part 571c extends by a predetermined height to the rear crossing the rear panel 65. Can be.

The light emitting member 572 may include a PCB 572a and an LED 572b, and may be disposed to face the rear of the LED 572b crossing the light guide plate 64. Light emitted from the light emitting member 572 may be reflected through the reflecting portion 571b to pass through the light cover 573.

One surface of the LED 527b irradiated with light from the light emitting member 572, that is, the light emitting surface 572c may be disposed in parallel with the light guide plate 64, and is disposed to face the reflective surface 571a. Can be. Therefore, the light emitted from the light emitting surface 572c is mostly irradiated toward the reflective surface 571a and passes through the light cover 573.

The light cover 573 may be configured such that a fine pattern is surface-treated on the surface, a coating process for diffusion, or the cover itself includes a diffusion agent, and is caused by light diffused in the process of passing through the light cover 573. The light cover 573 may emit light in the form of surface light. The light cover 573 may be positioned on the same line as the ends of the shield 571c and the door liner 56 of the light case 571 to have a sense of unity.

Since the light irradiation direction of the light emitting member 572 faces rearwardly intersecting with the light guide plate 64, it is possible to primarily prevent the light from being directly irradiated toward the light guide plate 64. By the part 571c, a part of the light irradiated from the light emitting member 572 may be blocked to face the light guide plate 64. In addition, the light cover 573 emits light in the form of surface light by passing through the light cover 573, and the light emitting member 572 may be brightened while the storage space behind the sub door 50 is brightly illuminated. It is possible to prevent the light of the direct light from being lowered the transparency of the light guide plate (64).

Meanwhile, in the refrigerator according to the embodiment of the present invention, various other examples of the door light may be possible in addition to the above-described example, which will be described with reference to the drawings.

29 is a partial cross-sectional view showing another example of the door light.

As shown in the figure, another example of the door light 57 includes a light case 571 and a light cover 573 having the same structure as the above-described example.

The light case 571 may be fixedly mounted between the rear panel 65 and the door liner 56, and may form the reflective part 571b and the shielding part 571c. In addition, the light cover 573 may be mounted in an opening of the light case 571 to transmit light emitted from the light emitting member 572.

On the other hand, the light emitting member 572 is disposed in the light case 571, it may be disposed in a slightly inclined form to face the rear of the sub-door 50. That is, the light emitting surface 572c to which light is irradiated from the LED 572b of the light emitting member 572 has an angle crossing the light guide plate 64, and may be disposed to be inclined somewhat backward. In addition, the light irradiated from the LED 572b is mostly irradiated between the inside and the rear of the sub door 50 and may be configured not to be directly irradiated to the light guide plate 64.

Accordingly, some of the light emitted from the light emitting member 572 is reflected by the reflecting portion 571b to illuminate the rear of the sub-door 50, and some of the light is transmitted through the light cover 573 to the sub-door. (50) The rear can be revealed.

In addition, a portion of light emitted from the light emitting member 572 facing the light guide plate 64 may be shielded by the shielding portion 571c, and direct light irradiation may be prevented from the light guide plate. In such a structure, even when the door light 57 is turned on, light may be directly irradiated onto the light guide plate 64 to prevent the light guide plate 64 from emitting light and deterioration of transparency.

30 is a partial cross-sectional view showing still another example of the door light.

As shown in the figure, another example of the door light 57 includes a light case 571 and a light cover 573 having the same structure as the above-described examples.

The light case 571 may be fixedly mounted between the rear panel 65 and the door liner 56, and may form the reflective part 571b and the shielding part 571c. In addition, the light cover 573 may be mounted in an opening of the light case 571 to transmit light emitted from the light emitting member 572.

The light emitting member 572 may be disposed inside the light case 571 and may be disposed to face the light cover 573. The light emitting surface 572c to which light is irradiated from the LED 572b of the light emitting member 572 may be disposed at an angle perpendicular to the light guide plate 64. The light emitting surfaces 572c of the LEDs 572b provided in the left and right door lights 57 may be located at positions facing each other. In this case, the light irradiated from the LED 572b may be irradiated in a direction facing each other toward the inner side of the sub door 50.

In addition, the light emitting member 572 may be disposed at the same height as at least the shielding portion 571c. Accordingly, the light irradiated over the shielding portion 571c of the light emitted from the light emitting member 572 illuminates the rear region of the sub-door 50, and the light irradiated toward the light guide plate 64 is It can be shielded by the shielding part 571c.

Therefore, some of the light emitted from the light emitting member 572 facing the light guide plate 64 is shielded by the shielding portion 571c and can prevent the light from being directly irradiated toward the light guide plate 64. Will be. In such a structure, since the light is not directly irradiated to the light guide plate 64 even when the door light 57 is turned on, the light guide plate 64 can be prevented from being emitted by light and the transparency is reduced. .

31 is a perspective view of a sub-door equipped with another example door light.

As shown in the figure, another example door light 57 may be mounted on the door liner 56 protruding rearwardly along the circumference of the panel assembly 60 from the door light 57.

The door liner 56 forms an underside of the sub door 50 and includes an opening that is shielded by the panel assembly 60. The liner protrusion 562 may be formed along a circumference of the opening of the door liner 56.

In addition, a door light 57 may be mounted to the liar protrusion 562. The door light 57 may have the same structure as in the above-described embodiment, and include a light cover 573. The light cover 573 is disposed on both sides of the liner protrusion 562 and emits light while the light is transmitted according to the operation of the door light 57.

The light cover 573 irradiates light toward the rear of the panel assembly 60, that is, the light guide plate 64, thereby illuminating the space behind the sub-door 50, and the panel assembly. Through 60, you can see the inside of the high.

At this time, the door light 57 is not structurally irradiated directly toward the light guide plate 64, so that the light guide plate 64 is maintained in a transparent state is seen through the see-through section 21 The inner space can be seen clearly.

32 is a sectional view of a refrigerator equipped with another example door light.

As shown in the figure, another example door light 57 may be mounted to the main door 40 shielded by the sub-door 50. The door light 57 may have the same structure as any one of the door lights of FIGS. 28 to 30, and only a mounting position may be located on the main door 40.

In detail, the sub door 50 may shield the opening of the main door 40, and the door light 57 may be mounted at both sides of the opening of the main door 40. The door light 57 is disposed in a direction facing each other to illuminate the opening area of the main door 40.

In this case, since the door light 57 may have the same structure as any one of the door lights of FIGS. 28 to 30, the door light 57 is irradiated toward the light guide plate 64 among the light emitted from the door light 57. It is possible to block or minimize the light.

Therefore, when the light is irradiated by the operation of the door light 57, the door side storage space behind the sub door 50 is revealed, so that the door side storage space is clear from the outside through the seeker 21. Can be seen. In addition, it is possible to prevent the light from being directly irradiated toward the light guide plate 64, and thus, the light guide plate 64 may be prevented from emitting light and the transparency may be reduced.

33 is a longitudinal cross-sectional view of the main door and the sub-door. 34 is an enlarged view of a portion C of FIG. 33. 35 is an enlarged view of part D of FIG. 33.

As shown in the drawing, when the user operates the front panel 61 on the front of the refrigerator 1 or the manipulation input unit 92, the display light 68 is turned on and the display ( 62 is turned on so that the panel assembly 60 can output a screen as shown in FIG. 33. In this case, the manipulation of the front panel 61 may be input to any one of a specific position, a touch number, or a pattern. Of course, if necessary, it may be possible to detect a user's manipulation using a separate physical button or sensor.

The display 62 may output a screen for displaying and manipulating the state of the refrigerator, and may output various screens such as an internet, an output using an image output external input device, and information on stored food.

In detail, the display light 68 disposed at the top and bottom of the light guide plate 64 together with the display 62 may be turned on by a user's manipulation. By the lighting of the display light 68, the light guide plate 64 diffuses and diffuses the light of the display light 68, thereby irradiating light toward the front display 62 with uniform brightness.

The light guide plate 64 emits light from the rear of the display 62 toward the display 62, and at the same time, the display 62 outputs a screen based on the input image information. Therefore, through the see-through section 21, the user can check the screen is clearly output.

In particular, since the light guide plate 64 includes a light diffusing agent 643, light guided into the light guide plate 64 may be diffused to uniformly light the entire light guide plate 64. That is, since a separate reflective sheet or pattern is not formed on the rear surface of the light guide plate 64, the light guide plate may be configured to allow a high inner perspective in a state where light is not irradiated, and the light is irradiated by the display light 68. In this case, the light guide plate 64 may be evenly brightened in the entire surface.

In addition, the operation of the display 62 or the operation of the door light 57 is controlled by the PCs 602, 603, 604, such as the Ticon board 602 or the docking PC 604 on the sub-door 50. Can be. In addition, these PCBs 602, 603, 604 may be disposed in a rear space of the sub door 50 partitioned by a barrier 711 forming an upper end of the support frame 70. Insulation material 531a may be filled in the front space of the sub door 50 partitioned by the barrier 711, and thus condensation may be prevented from occurring in the upper portion of the front surface of the sub door 50. .

On the other hand, when both the display light 68 and the door light 57 is turned on, in the state that the screen is output through the display 62, the inner space through the viewing unit 21, that is, the sub-door ( 50) It is also possible to selectively view the space behind.

That is, when the display light 68 and the display 62 are turned on and the information is output through the see-through part 21, the door light 57 is turned on to illuminate a high inner space. This can be seen together. Accordingly, the user may be able to check the information through the display 62 or manipulate the display 62 while inputting and processing the information while viewing the inside of the refrigerator.

The display light 68 and the door light 57 may be disposed in a direction crossing each other. The display light 68 may be disposed in front of the door light 57, and may be provided above and below the light guide plate so that light can be irradiated to the upper and lower ends of the light guide plate 64. The door light 57 may be disposed further rearward than the display light 68. The door light 57 may be disposed at both left and right sides of the light guide plate 64 to irradiate light to the rear space of the light guide plate 64. The storage space on the door side is revealed.

When the light guide plate 64 is viewed as a reference, display lights 68 may be disposed on the upper and lower sides, and door lights 57 may be disposed on both the left and right sides of the light guide plate 64 so as to form regions of the light guide plate 64 and the light guide plate 64. It can be configured to illuminate evenly.

38 is a partial cross-sectional view of a state in which a second bezel is output according to an embodiment of the present invention. 39 is a front view of a door in a state of a door in which the second bezel is output. 40 is a partial cross-sectional view of a state in which the second bezel is not output according to the embodiment of the present invention. 41 is a front view of the door in a state in which the second bezel is not output.

As shown in the figure, a first bezel 611 may be formed around the front panel 61 forming the front surface of the panel assembly 60.

The first bezel 611 is opaque to conceal the components coupled to the circumferential side of the panel assembly 60, and has a sufficient width so that the components coupled to the circumferential side of the panel assembly 60 are not visible. It can be formed to be.

However, when the width of the first bezel 611 is excessively wide, the area of the see-through part 21 provided inside the panel assembly 60 is narrowed, and the area of the see-through part 21 is narrow. If you lose, the inconvenience in use is increased and the appearance is not good.

The first bezel 611 may be formed to have a predetermined width at an outer end of the front panel 61, and an end L1 of the first bezel 611 may be around the panel assembly 60. It may extend to the same (or right) in FIG. 38 as the end L3 of the innermost located configuration (eg, the second spacer 66) of the configurations coupled to.

When the first bezel 611 has such a width, the first spacer coupled to the circumference of the panel assembly 60 by the first bezel 611 when the panel assembly 60 is viewed from the front. Configurations such as 63, second spacers 66, and the like, and their coupling structures, are obscured and become invisible.

However, the user always the panel assembly 60 at the center does bojineun at the sight unit 21, in accordance with the refrigerator 1 is disjoint from the panel assembly 60 such that at the center in a somewhat lateral side of the case of The viewing part can be seen. In this case, there is a problem that components coupled to the panel assembly 60 by the first bezel 611 may be exposed through the see-through part 21. Accordingly, a second bezel 622 may be provided to shield the remaining area not shielded by the first bezel 611.

The first bezel 611 may be formed to be exposed on the front panel 61 by printing, while the second bezel 622 may be configured to be output through the display 62 as needed. . Accordingly, the second bezel 622 may be referred to as a virtual bezel since the second bezel 622 is not formed physically, such as printing or bonding, but is formed by the screen output of the display 62. The second bezel 622 may be formed in the same color as the first bezel 611 so that the second bezel 622 may be integrally seen with the first bezel 611 upon output. It may be formed in a darker color so that a series of colors or internal perspective is not possible.

The second bezel 622 may be formed to have a predetermined width W2 at an outer side (left side in FIG. 38) rather than an end of the first bezel 611 or an end of the first bezel 611. . The end L2 of the second bezel 622 may extend to a position such that the components coupled around the panel assembly 60 are not visible when the user looks at the center of the refrigerator 1. Therefore, in the state in which the second bezel 622 is output, the circumference of the panel assembly 60 may be covered by the width of the first bezel 611 and the second bezel 622.

 The area of the see-through section 21 may be defined by the first bezel 611 or by the first bezel 611 and the second bezel 622 according to the screen output state of the see-through section 21. Can be. Since the second bezel 622 is configured to be output by the display 62, the second bezel 622 may be set to various widths according to a user's setting.

For example, when the see-through part 21 becomes transparent and faces the high inside through the see-through part 21, the panel assembly 60 becomes transparent and not only the high inside but also the panel assembly 60. As shown in FIG. 34, the second bezel 622 may be output as shown in FIG. 34.

Accordingly, as shown in FIG. 39, the circumference of the panel assembly 60 may be shielded by the first bezel 611 and the second bezel 622, and the seeker 21 may be the second bezel 622. It can be defined as the inner region of). In this state, even if the user looks at the perspective part 21 in the center of the refrigerator 1, that is, at the side of the transparent part 21, the inner circumference of the panel assembly 60 is extended. It may be covered by the second bezel 622.

In addition, when the transparent part 21 is in an opaque state, that is, when the display 62 is turned off or the transparent part 21 is opaque and the inside thereof is not visible, the display 62 is as shown in FIG. 40. The second bezel 622 is not output. In addition, as shown in FIG. 41, the display 62 outputs the second bezel 622 even when an image or an image is output through the display 62 without seeing the inside through the see-through part 21. You will not.

In this state, since the transparent part 21 is in a state of being opaque, even if the second bezel 622 is not output, the inside of the panel assembly 60 is not easily seen through the transparent part 21. The second bezel 622 is not output.

Accordingly, as shown in FIG. 41, the circumference of the panel assembly 60 is shielded only by the first bezel 611, and the transparent part 21 may be defined as an inner region of the first bezel 611. . In addition, the see-through part 21 in FIG. 41 is wider than the see-through part 21 in the same state as in FIG. 39, and therefore, the see-through part 21 is in a state where the see-through part 21 becomes opaque. It may look expanded. In addition, by the operation of the display 62, the seeker 21 can output a screen in a wider area, thereby improving convenience of use and appearance.

42 is a partial cross-sectional view illustrating an output state of the third bezel in another example of the panel assembly. 43 is a front view of the door in a state where the third bezel is output.

As shown in the figure, another example of the panel assembly 60 may include a front panel 61, a rear panel 65, a heat insulation panel 69, and a light guide plate 64. A display 62 may be disposed on the rear surface of the front panel 61, and the light guide plate 64 may maintain a proper distance from the display 62 by the first spacer 63.

In addition, a second spacer 66 is provided between the light guide plate 64 and the heat insulation panel 69 and between the heat insulation panel 69 and the rear panel 65 to provide the rear panel 65 and the heat insulation panel ( An insulating space may be formed between the 69 and / or between the insulating panel 69 and the light guide plate 64. In addition, a sealant 68 may be coated around the panel assembly 60 to seal the inside of the panel assembly 60.

Although not shown, display lights 68 may be provided at both ends of the light guide plate 64, and a touch sensor film may be attached to the front panel 61.

The display 62 and the light guide plate 64 may be formed to have a size corresponding to that of the front panel 61. Therefore, when the display 62 is operated, the screen 62 and the light guide plate 64 may be output to the entire front panel 61. Can be.

Thus, the display may output a third bezel 623 around the display 62. The circumference of the front panel 61 is in a transparent state in which no physical bezel of the printed or attached form, such as the first bezel 611 of the above-described embodiment, is formed, and only at the output of the third bezel 623. By doing so, the circumference of the panel assembly 60 may be covered.

Since the third bezel 623 is output by the operation of the display 62 like the second bezel 622 of the above-described embodiment, it may be referred to as a virtual bezel and may be output in black. The third bezel 623 may be variable to have various widths.

For example, as illustrated in FIG. 42, when the screen is output through the display 62 or when the seeker 21 is opaque, the third bezel 623 is connected to the front panel 61. It may extend from one end to a predetermined distance and may have a predetermined width W3. At this time, the end portions (L4, L4 ') of the third bezel 623 is the innermost of the configuration (for example, the first spacer 63 or the second spacer 66) inside the panel assembly 60. The inner components of the panel assembly 60 may be hidden when the user views the seeing portion 21 from the front side.

In addition, as shown in FIG. 43, the third bezel 623 may be formed to have a minimum width that may cover the internal components of the panel assembly 60 even when the screen is output through the display 62. Therefore, the fluoroscopy unit 21 is extended and defined to the maximum, and the screen is output through the fluoroscopy unit 21.

When viewing the inside through the see-through part 21, the see-through part 21 may be transparent, and at this time, since the circumferences of the panel assembly 60 may be seen, the display 62 The width of the three bezels 623 is further increased to enable output. In addition, when the width of the third bezel 623 is increased, even when viewed through the viewing part 21 in the lateral direction, the components around the panel assembly 60 are not visible.

On the other hand, when the user's position can be sensed in the refrigerator 1, the panel assembly may be formed by varying the width of the third bezel 623 or the second bezel 622 according to the above-described embodiment. The perimeter configuration of 60) can be covered, and the size of the see-through part 21 can be defined as an optimal size according to the situation.
