Referring to FIG. 3, a top end of the exterior member 400 is accommodated and fastened by the second connection rib 352, however a bottom end and side ends may also be fastened by the same construction as described above.

By way of connecting the exterior member 400, the exterior member 400 may define a front appearance of the door as being easily fixed to a front surface of the door 30.

Meanwhile, a light-emitting means 500 is provided between the exterior member 400 and the connection member 300. In other words, the light-emitting means 500 may be provided at a space between an edge of the exterior member 400 and the second connection rib 352.

The light-emitting means 500 may be a LED, and it is disposed to emit light toward an end of the exterior member 400, i.e. an edge of the exterior member 400.

In detail, the light-emitting means 500 includes a LED 510 for emitting light, and a board 530 on which the LED is mounted.

The board 530 is installed at an inner side of the exterior member accommodating portion 390, and a plurality of LEDs 510 may be provided in the exterior member accommodating portion 390. Here, the plurality of LEDs 510 may be continually mounted on one board 530.

However, the installing location of the board 530 is not restricted to the exterior member accommodating portion 390, and it may also be installed at an inside of the connection member by a separate mounting means.

Further, if the light-emitting means 500 can emit light to an outer end of the exterior member 400, the light-emitting means 500 may be mounted on inner side of the connection member 300 or one side of the outdoor panel 100.

Also, the light-emitting means 500 may also be another light source other than the LED.

The light-emitting means 500 may be provided at both of the first connection member 310, to which the exterior member 400 is attached, and the second connection member 330.

Meanwhile, the light-emitting means 500 may also be provided at any one of the first and second connection members 310, 330 of the door 30. That is, in case the light-emitting means 500 is provided at the first connection member 310, light can be emitted from top and bottom ends of the door assembly 100, 200 in opposite directions.

In case the light-emitting means 500 is provided at the second connection member 330, light can be emitted from left and right ends of the door assembly 100, 200 in opposite directions.

That is, the light-emitting means 500 may be installed along at least one end of the top, bottom, left and right ends of the exterior member 400.

The light emitted from the light-emitting means 500 is transmitted into the exterior member 400 via the end of the exterior member 400. In this course, the whole surface or considerable portion of the exterior member 400 may emit light.

That is, since the light emitted from the light-emitting means 500 is not directly incident to the front but is incident in a longitudinal direction of the exterior member 400, and therefore it may prevent dazzling of users.

Also, as described above, the exterior member 400 may be partly print-processed. And, the permeability of light emitted from the light-emitting means 500 can be adjusted according to the level of print-processing.

That is, the amount of light emitted from the light-emitting means 500 can be adjusted according to the transparency of a portion, which is print-processed, of the exterior member 400.

Hereinafter, the operation of the refrigerator having the above configuration will be described with reference to the drawings.

In a state where the door 30 of the refrigerator 1 is closed, the exterior member 400 is exposed to a front surface of the refrigerator and forms the appearance thereof.

In case the intensity of illumination at a site where the refrigerator 1 is placed is high enough, the light-emitting means 500 provided in the door 30 of the refrigerator 1 does not operate. And, the patterns expressed on the exterior member 400 can be recognized from the outside, so that these stylish elements can be transferred to the users.

Meanwhile, in case the intensity of illumination at the site where the refrigerator 1 is placed is lower than a predetermined value, the site is dark and therefore a front surface of the door 30, i.e. the patterns expressed on the exterior member 400 cannot be recognized by the users.

Accordingly, in case the intensity of illumination in the room is lower than a predetermined value, the light-emitting means 500 may be turned-on by an operation of the users or by a sensor detecting the intensity of illumination. If the intensity of illumination is turned on, the light emitted from the light-emitting means 500 is transferred into the exterior member 400 via an end of the exterior member 400.

That is, strong light which is emitted from a location adjacent to the end of the exterior member 400 is incident onto the end of the exterior member 400 which is transparent or semi-transparent, and the incident light is transferred along the inside of the exterior member 400 so that a front surface of the exterior member 400 or corresponding portion is lighted up.

Here, in case the light-emitting means 500 is disposed along the whole ends of the exterior member 400, the exterior member 400 is generally brightened, and in case the light-emitting means 500 is disposed along one end of the exterior member 400, the exterior member 400 is locally brightened.

Of course, even if the light-emitting means 500 is disposed along the whole edges of the exterior member 400, it is possible to selectively light-up some part of the exterior member 400 by controlling the operation thereof.

Meanwhile, the print-processing which blocks light from passing is worked out on a surface of the exterior member 400, the other portion except for the print-processed portion may emit light out of the door 30.

Also, in case patterns for transmitting light is expressed on the surface of the exterior member 400, light can be transferred through the patterns.

If semi-transparent pigment or semi-transparent sheet capable of controlling the transparency of light is attached to a surface of the exterior member 400, the light emitted through the exterior member 400 can be controlled.

The users can recognize the location of the refrigerator 1 and handle 31 by the help of the light emitted through the exterior member 400. And, the refrigerator may also serve as an illumination apparatus, since light is emitted therefrom.

The refrigerator according to the present invention can be implemented in embodiments other than the above-described embodiments without departing from the spirit and major characteristics of the present invention, in particular the refrigerator main body can also be implemented in many embodiments. Therefore, another embodiment of the refrigerator according to the present invention will be explained with reference to the drawings.

The refrigerator according to another embodiment of the present invention has similar structure as that of the above-described refrigerator, except for the application.

As described in the first embodiment, various patterns may be expressed on a surface of the exterior member 400. And, the patterns may be print-processed so that light can be transferred.

At the outer case 600, a mounting bracket 610 for guiding the installation of the exterior member 400 is provided. A plurality of mounting brackets 610 may be provided at both sides of the exterior member 400. Here, the mounting bracket 610 corresponds to the connection member of the first embodiment.

Further, the mounting bracket 610 is configured to accommodate both side ends of the exterior member 400. The exterior member 400 may be inserted between the plurality of mounting brackets 610.

On the contrary, the exterior member 400 may also be connected to a front surface of the main body 20 not by the mounting bracket 610 but by a separate adhesive or connecting element.

Also, a connection member 800 which connects the exterior member 400 to the main body 20 is provided at both sides of the exterior member 400.

The connection member 800 defines the appearance of a front surface and both side edges of the main body 20, and it is configured to engage with an end of the exterior member 400 or to cover both side ends of the exterior member 400.

Meanwhile, a display unit 33 is provided at an upper part of the exterior member 400, i.e. an upper part of the main body 20. The display unit 33 includes a video unit which displays the operational state of the refrigerator 3 and a plurality of input units which is able to input certain commands.

At one side of the display unit 33, a light-emitting means 500 for emitting light toward the exterior member 400 is provided.

In detail, the light-emitting means 500 includes a plurality of LEDs 510 for emitting light, and a board 530 on which the LEDs are mounted. The plurality of LEDs 510 are continually mounted on the board 530, and they are arranged at locations corresponding to the top of the exterior member 400 at regular intervals.

Also, the outer case 600 is provided with a mounting member 550 which allows the light-emitting means 500 to be installed at the outer case 600. The mounting member 550 is forwardly protruded from a front surface of the outer case 600, an accommodating space for receiving the light-emitting means 500 is formed in the mounting member 550.

The light-emitting means 500 may be disposed at one side of the exterior member 400 while being accommodated in the mounting member 550.

Meanwhile, the mounting member 550 may also be formed at the display unit 33 so that the light-emitting means 500 can be provided below the display unit 33.

Also, the light-emitting means 500 is provided at both sides of the exterior member 400.

Referring to FIG. 6, the exterior member 400 may be fixed to a front surface of the outer case 600 by the connection member 800. At least one side of the exterior member 400 may be connected to the connection member 800.

At one side of the exterior member 400, an exterior member accommodating portion 810 for receiving the exterior member 400 is formed. That is, the exterior member accommodating portion 810 is a space which is formed between the exterior member 400 and connection member 800.

On the exterior member accommodating portion 810, the light-emitting means 500 for emitting light toward the exterior member 400 is mounted. The light-emitting means 500 is disposed to emit light toward an end of the exterior member 400.

That is, since the light emitted from the light-emitting means 500 is not directly incident to the front but is incident in a longitudinal direction of the exterior member 400, and therefore this may prevent dazzling of users.

The operation of the refrigerator having the above-described configuration will be explained.

First, in case the intensity of illumination in a room where the refrigerator 3 is installed is high enough, the light-emitting means 500 is not operated because the patterns expressed on the exterior member 400 can be readily recognized.

However, in case the intensity of illumination in a room where the refrigerator 3 is installed is low, the light-emitting means 500 may be turned on. The control of the light-emitting means 500 may be automatically done by a sensor for detecting the intensity of illumination in a room, or it may also be done by On-Off operation of the users, as necessary.

If the light-emitting means 500 is turned on, the light from the LED 510 is incident on the end of the exterior member 400, and the incident light is transferred along the inside of the exterior member 400, thereby lightening up the whole or some part of the exterior member 400.

Here, the exterior member 400 may be print-processed in order to block light or to control the transmissivity of light. In this case, the light emitted to the outside via the front surface of the exterior member 400 can be controlled.

As described above, since an intense light from the light-emitting means 500 is not directly directed to the front and light is emitted through the exterior member 400, it can serve as an indirect light such as a mood lamp as well as the patterns expressed on the exterior member 400 can be further emphasized.

INDUSTRIAL APPLICABILITY

According to said refrigerator and refrigerator door, the location of the refrigerator door can be easily recognized as light is emitted from the exterior member by the light-emitting means, as well as it is possible to prevent dazzling of users as light is emitted through the end of the exterior member without exposing the exterior member, and therefore industrial applicability is deemed to exist therein.
