Also, the lighting device 36 may be mounted on the lower bracket 35 . In addition, the panel assembly 30 may further include a back cover 39 forming a rear surface.

Looking at this in more detail, the panel 31 may be formed in a rectangular plate shape and may be formed of a material capable of transmitting light. For example, the panel 31 may be formed of a glass material such as blue glass, white glass, or deposited glass, or another material capable of transmitting light such as ABS, PMMA, or PC. In addition, the panel 31 may be formed to have a set thickness so as not to be easily broken due to the nature of forming the exterior. The panel 31 may be formed thicker than the thickness of the light guide plate 33 . For example, the panel 31 may be formed to a thickness of approximately 3 mm to 5 mm. Also, the panel 31 may be referred to as a transparent plate or an out plate.

The panel 31 may be formed to be transparent so that light reflected by the light guide plate 33 may be transmitted. In this case, the transparency may be defined as a level at which light reflected from the light guide plate 33 is transmitted and irradiated to the outside so that it can be identified that the panel 31 shines in a specific color.

And, in all embodiments of the present invention, "transparency" and "transmission" may be defined as a state in which the light passes through and the set color can appear through the panel 31 .

Also, the panel 31 may be formed to have a color. That is, in a state in which the lighting device 36 is turned off, the color of the front surface of the door 20 can be expressed by the color of the panel. When the lighting device 36 is turned off, the color of the panel cannot be changed, and the user can select and mount a desired color through replacement of the panel assembly.

For example, a specific pattern or pattern may be printed on the panel 31 to have a specific color. In addition, a film printed with a pattern having a specific pattern or color is attached to the panel 31, surface treatment such as imprinting, nickname, or glass printing is performed on the panel, or a coating having a specific color and texture Alternatively, a deposition layer may be formed to form the exterior of the panel 31 .

In addition, the panel 31 may be configured such that the light irradiated from the lighting device 36 is transmitted, but elements behind the panel 31 are not reflected. That is, in the panel 31 , components inside the panel assembly 30 are visible to the outside through the panel 31 by the color of the panel 31 itself when the lighting device 36 is turned off. that can be prevented

At this time, the panel 31 may be formed with a color layer having a color. In an off state, it may be formed to have a color of at least 0 brightness other than black.

The panel 31 may form a front exterior of the panel assembly 30 exposed to the outside. Also, the panel 31 may be smaller than the size of the light guide plate 33 . Therefore, the light from the light guide plate 33 toward the panel 31 can be evenly irradiated throughout the panel 31, including the outer edge, and the entire panel 31 is not partially darkened but brightly lit. can be made

Also, the rear surface of the panel 31 may be mounted on the front surface of the fixing member 32 . At this time, the horizontal width of the panel 31 may correspond to the horizontal width of the fixing member 32, and therefore, the left and right both ends of the fixing member 32 and the panel 31 in a state in which the panel 31 is mounted. Left and right ends of ) are positioned on the same plane, and may form left and right both sides of the panel assembly 30 . Therefore, when the panel 31 is attached to the fixing member 32 and viewed from the front, components of the rear of the panel including the fixing member 32 are not exposed to the outside and are provided by the panel 31. The exterior of the front surface of the panel assembly 30 and the door 20 may be formed.

The light guide plate 33 may be positioned at a rear spaced apart from the panel 31, and the light emitted from the lighting device 36 disposed below the light guide plate 33 is forwardly directed toward the panel 31. Can be configured to guide.

For example, the light guide plate 33 may be formed of transparent acrylic, plastic, or transparent polymer material. In addition, a diffusion agent may be added to the light guide plate 33 to diffuse light incident on the light guide plate 33 or a pattern for light diffusion may be formed. Therefore, light can be transmitted to the panel 31 by the light guide plate 33, and at this time, the pattern of the light guide plate 33 can be set so that the entire front surface of the panel 31 can shine with uniform brightness. there is.

For example, the pattern density of the light guide plate 33 may increase upwardly from the center of the light guide plate 33 so as to have uniform brightness as a whole, and the pattern density may increase from the center to both left and right sides. It may be formed so that is high. In addition, a pattern may not be formed at a lower end of the light guide plate 33 or a pattern may have a relatively low density at a position closest to the lighting device 36 .

Also, the light guide plate 33 may be formed in the shape of the rectangular plate as a whole, and may be slightly larger than the size of the panel 31 . In detail, the light guide plate may be formed to have a smaller width than the left and right widths of the panel 31 and a longer length than the upper and lower lengths of the panel 31 so as to be mounted on the fixing member 32 .

In addition, a reflective layer (331 in FIG. 13) may be formed on a rear surface of the light guide plate 33 to direct light inside the light guide plate 33 forward. Accordingly, light moving along the light guide plate 33 may be directed toward the panel 31 . In addition, reflective layers are formed on both left and right ends and upper ends of the light guide plate 33, except for the lower part where the lighting device 36 is mounted, so that the light does not leak around the light guide plate 33 and penetrates the inside of the light guide plate 33. facing the panel 31 to make the panel 31 shine more brightly and uniformly.

Further, the light guide plate 33 may be supported from the rear by the back cover 39 and may be fixed by the fixing member 32 while maintaining a predetermined distance from the panel 31 .

A fixing member 32 may be provided between the panel 31 and the light guide plate 33 . The fixing member 32 fixes and mounts the light guide plate 33 and the panel 31, and can maintain a predetermined distance between the light guide plate 33 and the panel 31.

The front surface of the fixing member 32 may support the panel 31 and both left and right sides may restrain the light guide plate 33 disposed at the rear. The fixing member 32 may be referred to as a support member since the panel 31 and the light guide plate 33 are attached thereto, and may also be referred to as a transparent plate or a transmissive member since it is formed to transmit light. ) can be formed, so it can be called a panel frame.

On the other hand, the fixing member 32 may be formed of a material capable of transmitting light, and may be formed by injection or extrusion as a whole in a single configuration. That is, the fixing member 32 may be formed of a material having light transmittance and moldability. For example, the fixing member 32 may be formed of an optically transparent ABS material. In addition, the fixing member 32 may be formed of various transparent plastic materials, such as polycarbonate (PC) and acrylic. Light reflected from the light guide plate 33 may be transmitted and pass through the panel 31 .

Meanwhile, the light transmission performance and transparency of the fixing member 32 means the degree to which light emitted from the rear light guide plate 33 can pass through the fixing member 32 and illuminate the panel 31 .

Also, a light diffusing agent may be added during molding of the fixing member 32 . The light diffusing agent can diffuse the light passing through the fixing member 32 and make the light more evenly irradiated to the entire front panel 31 .

And, the remote device 2 may be a variety of devices capable of communication, such as a dedicated terminal, a mobile phone, a tablet, a portable PC, a desktop PC, a remote controller, and a Bluetooth speaker.

The user can generally manipulate and set the operating state of the lighting device 36, such as the operating time, operating conditions, and light emission color of the light source, through manipulation of the remote device 2. For example, simple manipulation and setting of the lighting device 36 may be possible through an application installed in a user's mobile phone or a dedicated program.

Selection of the changed color of the panel 31 through the remote device 2 will be reviewed with reference to FIG. 19 . The user can select a desired color of the panel 31 through the screen 2a of the remote device 2 such as a mobile phone or a terminal.

When the user manipulates the remote device 2, the remote device first outputs the menu screen 2b, and manipulates the panel color change menu 2b1 through the menu screen 2b.

When the user selects the panel color change menu 2b1, the remote device 2 outputs a color selection screen 2c from the menu screen 2b, and the user selects a panel 31 to be changed on the color selection screen. The position of and the color of the panel 31 to be changed can be selected.

In detail, a panel position selection menu 2c1 is displayed on the color selection screen 2c, and the panel 31 mounted on the door 20 at a desired position among the plurality of doors 20 can be selected. Also, the panel 31 of the door 20 selected by the user may be displayed in the panel location selection menu 2c1.

After selecting a desired position of the panel 31, the user can select and input the color selection menus 2c2 and 2c3 displayed on the color selection screen 2c. For example, the color selection menus 2c2 and 2c3 may display all colors that can be displayed on the panel 31 in the form of a color picker capable of checking and extracting color codes. The color selection menus 2c2 and 2c3 may be referred to as a palette because it is possible to combine and select various colors.

The color selection menus 2c2 and 2c3 may include a circular first selection part 2c2 and a bar-shaped second selection part 2c3. The first selector 2c2 may select a color, and the second selector 2c3 may select the intensity of the selected color.

In this way, the user can select the color of the panel 31, that is, the third color among various colors through the color selection menus 2c2 and 2c3. Of course, the color selection menus 2c2 and 2c3 may be configured to allow input in the form of characters, codes, and numbers.

Also, according to the user's selection of the third color, the control unit 13 controls the lighting device 36 to be turned on in the second color so that the panel 31 can be seen in the third color.

Also, the user may input a color through the manipulation unit 14 provided in the refrigerator 1 without using the remote device 2 .

Also, the refrigerator 1 and the remote device 2 may be connected to the server in a network state, and thus, the color of the panel 31 of the refrigerator 1 may be input through the server 3.

Meanwhile, the operation of the lighting device 36 may be performed through a user's manipulation of the control unit 14 . The control unit 14 may be provided on one side of the refrigerator 1, and may be provided on one side of the cabinet 10, for example. Of course, the control unit 14 may be provided on the door 20 as needed, and may be input by a manipulation such as touching or knocking on the panel 31 . That is, the user can set the operation of the lighting device 36 by directly manipulating the control unit 14 and can turn the lighting device 36 on or off.

Also, the lighting device 36 may be operated by a sensor. The sensor may be, for example, a user detection sensor 151 that detects a user's proximity. For example, the user detection sensor 151 may use various devices capable of detecting a user approaching the refrigerator, such as an infrared sensor, an ultrasonic sensor, or a laser sensor.

Also, the user detection sensor 151 may be provided on one side of the cabinet or door 20 and may be disposed in various positions to detect the user's proximity. In addition, a plurality of the sensors may be provided at different locations.

Therefore, when the user approaches the refrigerator 1 by a set distance to use the refrigerator 1, the user detection sensor 151 detects this and transmits a signal to the control unit 13 and the lighting device (36) can be turned on. Also, when the user moves away from the refrigerator 1, the user detection sensor 151 detects this and transmits a signal to the control unit 13 so that the lighting device 36 is turned off.

In detail, when the user sensor 151 detects that the user is very close to the refrigerator 1, the lighting device 36 may be turned off or the brightness may be gradually dimmed to prevent the user from glare. . In addition, when the user moves away from the refrigerator 1 again, the lighting device 36 may be turned on again or returned to its original brightness.

The sensor may be an illuminance sensor 152. The illuminance sensor 152 senses the illuminance of an indoor space and may be disposed at the same position as the position where the user sensor 151 is disposed.

Also, the lighting device 36 may be operated according to the detected illuminance of the illuminance sensor 152 . For example, when the detected illuminance of the illuminance sensor 152 is below the set illuminance and becomes dark, the control unit 13 turns on the lighting device 36, and the detected illuminance of the illuminance sensor 152 changes to the set illuminance. When an abnormality occurs and the light becomes bright, the controller 13 may turn off the lighting device 36 .

Meanwhile, the sensors may include both the illuminance sensor 152 and the user sensor 151, and the illuminance sensor 152 and the user sensor 151 act in combination to control the control unit 13. The lighting device 36 may be controlled to be turned on or off.

Also, the controller 13 may be connected to the microphone 18. Therefore, according to the voice signal received from the microphone 18, the LED 362 can be made to shine in a set color, and the front color of the door 20 indicates the input state of the voice signal or the set state of the function. You may.

For example, when a user's temperature control signal is input through the microphone 18, the control unit 13 adjusts the temperature inside the refrigerator to a set temperature, and the color of the front surface of the door 20 corresponds to the corresponding temperature. It is possible to operate the lighting device 36 so that this changes.

Meanwhile, the lighting device 36 may be turned on and off at a time set by the timer 16 . That is, the lighting device 36 may be turned on according to the time when the user is mainly active, and maintained in an off state outside of a set time range. In addition, the lighting device 36 may be turned off during the day and turned on at night regardless of the actual illuminance.

In addition, the brightness and color of the front surface of the door 20 may be adjusted according to a user's setting regardless of the operating state of the refrigerator 1 .

Also, the lighting device 36 may include a state in which brightness is adjusted in addition to an on state and an off state. That is, the controller 13 can adjust the output of light emitted through the lighting device 36 to vary the brightness of the panel 31 . In addition, the operating state of the refrigerator 1 may be indicated through the brightness of the panel 31 .

Meanwhile, looking at the operating state of the lighting device 36 operated by the control unit 13, as shown in FIG. 19, when the lighting device 36 is turned on according to the instructions of the control unit 13 , the light emitted from the LED 362 may be radiated toward the lower end of the light guide plate 33 . At this time, the light emitted from the LED 362 may be emitted in a second color selected by the controller 13 . That is, the LED 362 is an RGB LED and emits light of a second color corrected by the control unit 13 so that the surface of the panel 31 can shine in the third color selected by the user.

Light incident through the lower end of the light guide plate 33 may be diffused and reflected along the light guide plate 33 and may move along the light guide plate 33 . At this time, the light guided by the light guide plate 33 may be reflected forward by the reflective layer 331 and pass through the panel 31 to be transmitted to the outside.

Light directed forward through the light guide plate 33 passes through the fixing member 32 to illuminate the panel 31 , and the front surface of the door 20 may shine with a set brightness or color.

At this time, the light guide plate 33 can radiate light of sufficient brightness forward from the entire surface by the LEDs 362 disposed at both ends of the LED mounting portion 361a, and thus the both ends of the panel 31 The whole including the light can be illuminated with uniform brightness.

Meanwhile, the lighting device 36 may be disposed at the lower end of the panel assembly 30 and may be fixed inside the lower bracket 35 so as not to move. Also, the light guide plate 33 is maintained in a fixed state by the fixing member 32 . Therefore, the light source 362 of the lighting device 36 and the lower end of the light guide plate 33 facing the light source 362 can maintain a state aligned with each other, so that the light from the light source 362 is effectively applied to the light guide plate ( 33) can be investigated.

In particular, even when the door 20 is repeatedly opened and closed, the lighting device 36 and the light guide plate 33 can maintain an accurate position, and it is possible to ensure that the panel 31 shines at a set luminance.

In particular, the light guide plate 33 has a structure supported from below by its own weight, and thus, a set distance G can be maintained between the lower end of the light guide plate 33 and the upper end of the light source 362 . Accordingly, the light emitted from the light source 362 can be effectively incident on the lower end of the light guide plate 33, and the luminance of the panel 31 can be guaranteed and uniform brightness can be provided.

Also, the lighting device 36 may be located below the upper end of the front part 351 of the lower bracket.
