    Fig. 5 is an exploded perspective view illustrating a first door of the cooling compartment, according to the first embodiment. Fig. 6 is a cross-sectional view taken along line I-Γ of fig. 1.
    Referring to figs. 5 and 6, the first door of the cooling compartment 100, according to the first embodiment, includes a part of the outer door 100 that defines an exterior of the first door of the cooling compartment 100, a part of the inner door 150 spaced behind the door. part of the outer door 110, and a body of the door 130 coupling the part of the outer door 110 and the part of the inner door 150 to each other. An edge of the inner door 150 is provided with a sealing element 160 that seals the space between the first door of the cooling compartment and the sub-holder 80.
    9/23
    In detail, the external door part 110 is provided with the viewing window 105 through which the interior of the refrigerator 1 can be seen from the outside. For this purpose, the outer door portion 110 can be formed of transparent glass.
    In addition, a specific lamination or deposition process can be carried out on the transparent glass, which will be described later with reference to the figures.
    The rear surface of the outer door portion 110 is provided with a coupling surface 112 for coupling to the door body 130. The coupling surface 112 has a certain area along an edge of the door body 130.
    The front surface of the door body 130 can be coupled to the coupling surface 112 via heat welding or supersonic welding. However, this report is not limited to this, and thus, the door body 130 can be coupled to the external door part 110 by a separate coupling element.
    The lower portion of the outer door portion 110 is provided with a support 115 that supports the lower portion of the door body 130. The support 115 extends to the rear side of the outer door portion 110.
    The door body 130 includes an insulating space 135 that has a hollow rectangular shape and functions as an insulating part to insulate the cooling compartment 30. The front portion of the insulating space 135 is covered by the outer door part 110. As described above , the outer door portion 110 can be coupled to the front surface of the door body 130.
    The rear portion of the insulating space 135 is covered by the inner door part 150. The door body 130 includes a support reinforcement 134 that supports the inner door part 150.
    The support reinforcement 134 protrudes back around the insulating space 135. The part of the inner door 150 coupled to the rear portion of the door body 130 can be supported by at least one support reinforcement portion 134. At this point, the door part internal 150 can be adhered to the support reinforcement 134. In this case, the support reinforcement 134 functions as a coupling reinforcement.
    As a result, the insulating space 135 has a thickness corresponding to the thickness of the door body 130.
    When the outer door part 110 and inner door part 150 are coupled to the front and rear portions of the door body 130, a layer of
    10/23 insulating gas can be formed in the insulating space 135. The insulating gas layer can include at least one of the air, argon (Ar) and krypton (Kr), which have high insulating performance.
    The insulating space 135 can be maintained in a vacuum state. In this case, the insulating space 135 has no means of heat exchange and, thus, a heat exchange between the cooling compartment 30 and the outside can be minimized.
    A coupling part of the seal 133, which is coupled to the sealing element 160, is disposed outside the support reinforcement 134. The sealing element 160 is coupled to the coupling part of the seal 133 to prevent a leakage of cold air through the space between the first door of the cooling compartment 100 and the sub-holder 80.
    The door body 130 is provided with a door shoulder 132 that has direct contact with the main body 10, when the first door of the cooling compartment 100 is closed on the main body 10. The shoulder of the door 132 corresponds with a main shoulder 19 (refers to fig 4) and is tilted in a certain direction.
    Although not shown, a sealing element can be arranged between the shoulder of the door 132 and the main shoulder 19.
    The inner door part 150 may include a transparent material to show the interior of the cooling compartment 30. For example, the inner door part 150 may include a transparent plate that is formed of glass or plastic to transmit light entirely.
    Figs. 7 to 9 are schematic views illustrating a process that is carried out on an outer door part according to the first embodiment. Fig. 10 is a cross-sectional view illustrating a configuration of a part of the outer door according to the first embodiment.
    Referring to figs. 7 to 10, a treatment (process) for a glass element will now be described, according to the first embodiment.
    First, a lamination process is carried out on a glass element 111 which is a major part of the outer door part 110. The glass element 111 can be formed of a transparent material. Here, the transparent material can be defined as a material capable of transmitting light entirely.
    Through the lamination process, a treated lamination layer 112 can be formed on a front surface 111a constituting the surface
    11/23 front of the glass element 111. The treated laminating layer 112 can be formed through a glass lamination process.
    The glass lamination process is a method for expressing various perceptions according to lighting or a viewing angle, in which the glass paint is applied over the glass element 111 and is then heated to a temperature ranging from about 600 ° C to about 700 ° C, so that the glass paint is absorbed in the glass element 111.
    In detail, the treated lamination layer 112 includes a lamination layer 113, a reflective lamination layer 114 and a protective coating part 115. Lamination layer 113 can be printed using a screen printing lamination method, called the serigraphy. The screen printing lamination method makes it possible to freely express various colors and use various base materials and is not limited in size and material. In current mode, the front surface 111a of the glass element 111 can be painted silver or blue.
    The reflective lamination layer 114 is arranged on the upper side of the lamination layer 113 so that a color printed on the lamination layer 113 is presented through the glass element 111 without distortion. That is, the reflective lamination layer 114 is configured to increase the color reflectivity of the light that passes through the lamination of layer 113. The reflective lamination layer 114 and lamination layer 113 can reduce the transparency of the glass element 111. reflective lamination layer 114 has a thickness ranging from about 10 pm to about 40 pm to reflect more of the light that passes through lamination layer 113. When the reflectivity of light is improved, the intensity of the light reflected through the lamination 113 increases and thus a color of lamination layer 113 is more vivid. A gradation effect of the glass element 111 can be achieved using the reflective lamination layer 114.
    The protective coating part 115 can be formed of epoxy resin to protect the lamination layer 113 and the reflective lamination layer 114. The protective coating part 115 can be formed by lamination on the upper portion of the reflective lamination layer 114.
    The treated laminating layer 112 configured as described above has a predetermined color to filter the transparent glass element 111 to a predetermined extent and, therefore, a predetermined pattern is formed on the glass element 111.
    12/23
    Here, the term "filter" denotes making the glass element 111 opaque at a predetermined point.
    After the treated laminating layer 112 is formed on the glass element 111, a deposition process is carried out on a rear surface 111b of the glass element 111. Through the deposition process, a treated deposition layer 116 is formed on the rear surface 111b . The term "treated deposition" denotes processing an irregular surface of the glass element 111 to form a uniform (smooth) surface, and coloring a surface of the glass element 111. Once the treated deposition layer 116 is arranged on the glass 111, a portion of light can be emitted from inside the cooling compartment 30 to the outside.
    In detail, the treated deposition layer 116 can be formed through an evaporation process. In the evaporation process, a metal source is heated, melted and evaporated at an elevated temperature to be deposited on a base material (a plate), that is, in the glass element 111.0 evaporation process uses a principle that, when a metal is heated and evaporated at an elevated temperature for a short period of time, the metal particles leave the evaporated metal and are attached to a surface of a low temperature base material to form a thin metal film therein. An electron beam can be used as an evaporation element in the evaporation process. A multilayer of a metal or metal oxide is heated, melted, and evaporated by the electron beam to form a film on a surface of a base material. Since the metal oxidizes at a high temperature in the evaporation process, the evaporation process is carried out in a vacuum state, and thus, it can be called a vacuum evaporation process.
    Consequently, when the treated deposition layer 116 is formed on the glass element 111, an uneven surface of the glass element 111 is changed to a smooth surface and, thus, the outer door part 110 appears more luxurious.
    The metal or metal oxide can include SiO 2 or TiO 2 .
    When SiO 2 is used as a raw material to be deposited on the glass element 111, the glass element 111 can be colored approximately blue. When TiO 2 is used as a raw material to be deposited on the glass element 111, the glass element 110 can be colored approximately silver. As described above, when SiO 2 or
    13/23
    TiO 2 is used as a raw material to be deposited on the glass element 111, the glass element 111 can be of various colors, and thus, the outer door part 110 can have a desired color.
    In addition, direct glare from the light emitted from the first light-emitting part 17 and the second light-emitting part 87 can be avoided. That is, since the transparency of the glass element 111 is decreased (increased opacity), the light emitted by the first light-emitting part 17 and the second light-emitting part 87 is observed as soft light from the outside. Through the evaporation process, the glass element 111 is improved in rigidity and corrosion resistance, and is more resistant to variations in temperature and humidity. Although the rear surface 111b of the outer door portion 110 is exposed to the gas in the insulating space 135 for a long time, its discoloration can be avoided.
    Alternatively, a sputtering process can be used as a deposition process for the glass element 111. In the sputtering process, the plasma is formed by a high voltage generated from a voltage generating device so that the ions of the plasma collide with a target to attach metal atoms to a base material, that is, to a surface of the glass element 111, thus forming a metal film. In detail, Argon gas (Ar +) can be used to form plasma ions, and tin (Sn) can be used as the target. Thus, when the argon gas is ionized by a high voltage and collides with the tin, the particles that come out of the tin are attached to the glass element 111 to form a metal film. Alternatively, aluminum (Al) can be used as the target. In this case, the argon gas collides with the aluminum, and the particles coming out of the aluminum are attached to the glass element 111 to form a metal film.
    After the treated deposition layer 116 is formed on the rear surface 111b, a filter layer 117 is formed on an edge of the rear surface 111b. The filter layer 117 can be formed using the lamination process described above and can additionally render the glass element 111 opaque.
    The lamination process can be carried out several times for the filter layer 117 to effectively filter the glass element 111. The filter layer 117 formed on the rear surface 111b prevents the emission of light by the first and the second light emitting part 17 and 87 to the outside. This is,
    14/23 the light emitted by the first and the second light-emitting part 17 and 87 is reflected by the filter layer 117. Thus, the light emitted by the first and the second light-emitting part 17 and 87 can be transmitted through the region of the treated deposition layer 116, except filtering layer 117. As described above, since the treated deposition layer 116 has a predetermined color and opacity, the light emitted by the first and the second light-emitting part 17 and 87 passes partially through the treated deposition layer 116. Consequently, soft, dull light is emitted, and the items stored in the cooling compartment 30, i.e., in the first receiving part 70 and in the sub-holder 80, can be seen from the outside. In this case, the viewing window 105 to show the interior of the cooling compartment 30 can correspond to the region of the treated deposition layer 116. As a result, a user can perceive the positions of the items visually with comfort.
    A refrigerator operation will now be described according to the first embodiment.
    The light-emitting manipulator 90 can be pressed to perceive items stored in the cooling compartment 30, that is, in the first receiving part 70 and in the second receiving part of the sub-holder 80.
    Then, the first light-emitting part 17 and the second light-emitting part 87 can be connected, and then the light emitted from there is transmitted through the inner door part 150 and the outer door part 110, which are formed of materials transparent, and is output to the outside.
    At this point, since the treated deposition layer 116 and the treated lamination layer 112, which have predetermined colors and opacity, are arranged on the part of the outer door 110, a portion of the light emitted from the first and second emitting parts of light 17 and 87 is reflected by the part of the external door 110, and the other is transmitted by the viewing window 105 and, thus, it is smoothly emitted to the outside. At this point, the items stored in the first receiving part 70 and in the subport 80 can be seen from the outside. After a predetermined time has elapsed, the first light-emitting part 17 and the second light-emitting part 87 can be turned off, thereby reducing their energy consumption.

    Fig. 13 is a perspective view illustrating a refrigerator according to a fourth embodiment. Figs. 14 and 15 are seen in cross-section illustrating a drive unit for driving a refrigerator display unit, according to the fourth embodiment. Fig. 16 is a perspective view illustrating an operation of a refrigerator viewing window, according to the fourth embodiment.
    Hereinafter, a description of the components identical to those in fig. 1 to 12 will be omitted.
    Referring to figs. 13 to 16, the first door of the cooling compartment 100, according to one embodiment, includes the display unit 50 for displaying a refrigerator operating status, the light-emitting manipulator 90 for handling the first and second emitting parts light 17 and 87 and display unit 50, and input parts 92 to command the refrigerator to operate.
    In detail, the display unit 50 can be arranged in a region corresponding to the display window 105. When the first and second light-emitting parts 17 and 87 are turned off, the display unit 50 is displayed outside the refrigerator, and it is difficult to see the interior of the cooling compartment 30.
    Inlet part 92 is manipulated to enter a command to operate the refrigerator, for example, a command to control a temperature of the freezer compartment 20 and a temperature of the refrigeration compartment 30, and a command to operate a special refrigeration compartment .
    When the light-emitting manipulator 90 is manipulated, the display unit 50 or the first and second light-emitting part 17 and 87 can be selectively turned on or off. A related operation (control) method
    18/23 with these on / off operations will be described later with reference to the figures.
    The rear surface of the first door of the cooling compartment 100 is provided with a guide unit 400 for operating the display unit 50. The drive unit 400 can be arranged in the isolation space 135.
    In detail, the drive unit 400 includes: an upper plate 420 and a lower plate 460, which are spaced apart and arranged vertically; a first transparent conductor 430 disposed under the upper plate 420; a second transparent conductor 450 disposed on the bottom plate 460; and a liquid crystal layer 440 disposed between the first and the second transparent conductor 430 and 450. The upper plate 420 and the lower plate 460 can be made of glass or transparent plastic, which transmit light completely.
    The first and second transparent conductors 430 and 450 are transparent electrodes for conducting the liquid crystal layer 440, and can be made of tin and indium oxide (ITO). The first and second transparent conductors 430 and 450 can have predetermined conductivity and transmissivity.
    The first and second transparent conductors 430 and 450 can be actuated as positive and negative electrodes by energy supplied from a 490 power supply, and thus an alignment of the liquid crystal layer 440 is determined in a predetermined direction according to the conduction of the first and second transparent conductors 430 and 450.
    The first and second transparent conductor 430 and 450 can constitute one of the pixels including a plurality of electrodes. When energy is applied to a part of the electrodes, an alignment of the liquid crystal layer 440 corresponding to the part of the electrodes is determined in a predetermined direction.
    A character or a numeral displayed on the display unit 50 is expressed in a specific form by the conduction of the first and the second transparent conductor 430 and 450 constituted in a pixel unit and the activation of the liquid crystal layer 440 corresponding to the first and second conductor transparent 430 and 450. The direction of light vibration can be determined according to a degree of alignment of the liquid crystal layer 440, for example, according to an alignment angle from a vertical axis.
    19/23
    A first polarization plate 412 is disposed on the upper plate 420, and a second polarization plate 414 is disposed under the lower plate 460, and uses polarization as a property of light to transmit light having only a predetermined direction. For example, the light that passes through the first polarization plate 412 can be polarized vertically with respect to an optical axis, and the light that passes through the second polarization plate 414 can be polarized horizontally with respect to the optical axis. The liquid crystal layer 440, the first and second transparent conductor 430 and 450, the first and second polarization plates 212 and 214 and the upper and lower plates 420 and 460 can form an LCD panel.
    The backlights 480 for emitting light and a light guide panel 470 are arranged under the second polarization plate 414. The light guide panel 470 is arranged between the backlights 480 to guide the light emitted from the units backlight 480 for the LCD panel, that is, for the liquid crystal layer 440. The backlights 480 and the light guide panel 470 can constitute a backlight unit.
    A drive unit 400 operation will now be described.
    When the backlights 480 emit light, the light guide panel 470 uniformly transmits light to the liquid crystal layer 440. The light transmitted by the light guide panel 470 is filtered through the second polarization plate 414, so that only light that has a first direction passes through the second polarization plate 414. The light that passes through the second polarization plate 414 is transmitted to the liquid crystal layer 440 through the lower plate 460. At this point, the crystal layer liquid 440 is driven by the first and second transparent conductors 430 and 450, and an alignment thereof is determined in a predetermined direction. The light that passes through the liquid crystal layer 440 can change its direction to a different direction than the first direction.
    Then, light is transmitted from the liquid crystal layer 440 of the upper plate 420 and the first polarization plate 412. At this point, only light that has a second direction passes through the first of the polarization plate 412. When a The direction of vibration of the light that passes through the liquid crystal layer 440 is the same as the second direction of the first polarization plate 412, the light passes entirely through the first polarization plate 412 and thus a white color can be seen. On the contrary, when a direction of light vibration that passes through the liquid crystal layer
    20/23
    440 is perpendicular to the second direction of the first polarization plate 412, the light is blocked by the first polarization plate 412 and thus a black color can be seen. That is, a white or black color can be seen in the display unit 50 according to an alignment of the liquid crystal layer 440 and a direction of the vibration of the light emitted from the backlights 480. Although not shown, a filter of color can be arranged on the upper plate 420. In this case, the light that passes through the upper plate 420 can have a predetermined color.
    As a result, a character (numeral) or figure displayed on the display unit 50 can be formed by conducting the liquid crystal layer 440 and filtering the light through the first and second polarization plates 412 and 414.
    When the power applied to the first and second transparent conductors 430 and 450 is cut, and the backlights 480 are switched off, the light passes only through the driving unit 400. In this case, the information (character and figure) to be displayed through the display unit 50 it is transparent and thus invisible on the first door of the cooling compartment 100. When the first and second light-emitting parts 17 and 87 emit light, the display unit 50 transmits the light to the outside of the first door of the cooling compartment 100. Thus, as illustrated in fig. 11, the display unit 50 is invisible on the first door of the cooling compartment 100, and items stored in the first receiving part 70 and the sub-holder 80 can be seen through the viewing window 105 on the outside.
    A refrigerator operation will now be described, according to one modality.
    When the first door of the cooling compartment 100 is closed and the drive unit 400 is activated, the display unit 50 is displayed on the first door of the cooling compartment 100. In this state, the light-emitting manipulator 90 can be pressed to observe items stored in the cooling compartment 30, that is, in the first receiving part 70 and the second receiving part (also called 80).
    When the light-emitting manipulator 90 is pressed, the energy applied to the power source 490 and the backlights 480 are cut off and a numeral and a character displayed on the display unit 50 disappear. At this point, the first and second light-emitting parts 17 and 87 can be turned on and the light
    21/23 emitted by the first and the second light-emitting part 17 and 87 can be transmitted to the outside by the transparent part of the inner door 150 and the transparent part of the outer door 110.
    Since the light-emitting manipulator 90 can be manipulated to observe an item in the cooling compartment 30, the light-emitting manipulator 90 can be called a view conversion input switch.
    In this case, since the treated deposition layer 116 and the treated lamination layer 112, which have predetermined colors and opacity, are arranged on the part of the outer door 110, a portion of the light emitted from the first and the second emitting part of light 17 and 87 is reflected from the part of the external door 110, and the other is emitted through the viewing window 105 and, thus, the light is emitted smoothly to the outside.
    At this point, the items stored in the first receiving part 70 and the subport 80 can be seen from the outside. After a predetermined time has elapsed, the first light-emitting part 17 and the second light-emitting part 87 can be switched off, thereby reducing energy consumption.
    Although the viewing window 105 is provided to the first door of the cooling compartment 100 in the current mode, the viewing window 105 can be provided to one of the first and second doors of the freezing compartment 21 and 22, according to another embodiment. Additionally, an item stored in the freezing compartment 20 can be seen outside.
    Fig. 17 is a block diagram illustrating a refrigerator configuration according to an embodiment. Fig. 18 is a flow chart illustrating a method for controlling a refrigerator according to an embodiment.
    Referring to figs. 17 and 18, the refrigerator 1, according to an embodiment, includes the input part 92 for introducing a predetermined command for the display unit 50, the light-emitting manipulator 90 for connecting the first and the second light-emitting part 17 and 87 to observe an item stored in the cooling compartment 30, and a timer 320 used to count a duration time that the light-emitting manipulator 90 remains on.
    Refrigerator 1 includes the drive unit 400 to drive the display unit 50, the first light-emitting part 17 to emit light
    22/23 for the first receiving part 70, and the second light-emitting part 87, for emitting light for the receiving part 80.
    In detail, the drive unit 400 includes the power source 490 to apply energy to the first and second transparent conductors 430 and 450, and the backlights 480 arranged behind the liquid crystal layer 440 to emit predetermined light.
    Refrigerator 1 includes a control unit 300. The control unit 300 controls the drive unit 400 and the first and second light-emitting parts 17 and 87 according to the input commands of the input part 92 and the emitter manipulator. light 90.
    Referring to fig. 18, a method for controlling a refrigerator will now be described, according to the current mode.
    When the door of the first cooling compartment 100 is closed in operation S11, the display unit 50 is switched on to display a refrigerator operating status on the front side of the display window 105. The display unit 50 can be switched on even when the refrigeration compartment door first 100 is opened. In detail, when the driving unit 400 is activated to supply power to the power source 490, and the backlights 480 emit light to the light guide panel 470, the display unit 50 is switched on in operation S12.
    In this state, it is determined in operation S13 whether a command is entered via the light-emitting manipulator 90. If a command is entered via the light-emitting manipulator 90, the display unit 50 is switched off in operation S14, and the first and second light-emitting components 17 and 87 are connected in operation S15. While the display unit 50 is turned off, the unit's LCD panel and backlight are stopped.
    The light emitted from the first and second light-emitting parts 17 and 87 passes through the driving unit 400, the display unit 50, and the viewing window 105, and is emitted to the outside. At this point, items stored in the first and second receiving parts 70 and 80 can be shown outwards in operation S16.
    If a command is not entered via the light-emitting manipulator 90, operation S12 is repeated. That is, the display unit 50 remains on.
    When the first and second light-emitting components 17 and 87 are connected, in operation S17 it is determined whether a certain time has elapsed.
    An on time of the first and second light-emitting parts 17 and 87, that is,
    23/23 a time in which the light is transmitted by the first and second light-emitting parts 17 and 87 to the outside, is measured by timer 320, and the control unit 300 determines whether the time measured by timer 320 is longer than set time
    If the time measured by timer 320 is greater than the determined time, the first and second light-emitting parts 17 and 87 are switched off in operation S18. Then, the conductive unit 400 is operated again to switch on the display unit 50 in operation S19. That is, energy is applied to power source 490 to drive the first and second transparent conductors 430 and 450 and the liquid crystal layer 440, and light is emitted from the backlights 480 to the liquid crystal layer. 440.
    On the contrary, if the time measured by timer 320 is not longer than the determined time, the items are continually shown to the outside.
    As such, when the display unit 50 is displayed on the first door of the cooling compartment 100 in a normal state, an operating state of the refrigerator 1 can be verified. In addition, when the light-emitting manipulator 90 is manipulated to observe an item in the refrigerator 1, the display unit 50 disappears and the first and second light-emitting part 17 and 87 are operated.
    Consequently, refrigerator 1 can be conveniently used, thereby leaving users satisfied.
