The image providing unit 100 is a beam projector, and an image irradiated by the image providing unit 100 is displayed on the front surface of the door 20 through the air.

Therefore, the door 20 is not provided with a display capable of reproducing images on its own, such as an LCD. Therefore, since the thickness of the heat insulating material does not become thinner inside the door for installing the display when the door 20 is manufactured, the heat insulating performance of the door can be improved.

In addition, since it is not necessary to provide an electric device for transmitting power or data to the display mounted on the door 20, the door 20 can be easily manufactured.

The image providing unit 100 is installed on the door 20 so that the image providing unit 100 can be rotated together with the door 20 when the door 20 is rotated. Of course, the image providing unit 100 may be disposed on the upper side of the cabinet 10, but may be arranged to protrude forward from the front surface of the door 20.

The door (20) may be provided with a display unit (30) capable of displaying an image illuminated by the image providing unit (100). The display unit 30 displays an image to be illuminated by the image providing unit 100. At this time, the display unit 30 is not an electric device that displays electricity by supplying electric power, and reflects the image provided by the image providing unit 100 to display a related image to the user.

The display unit 30 is provided under the image providing unit 100. The display unit 30 may include a flat surface having a rectangular shape so that an image provided by the image providing unit 100 may be displayed. In the image providing unit 100, a rectangular image is provided, and the display unit 30 can display the related image as a whole.

The flat surface provided on the display unit 30 may have the same one color. The image providing unit 100 can provide various images transmitted from the user terminal 200 as well as information related to the refrigerator. Since the display unit 30 has a uniform color as a whole, The distortion of the image is not generated.

Since the image providing unit 100 is disposed on the upper side of the door 20, the image providing unit 100 provides the image downward.

When the door 20 is disposed at the center with respect to the width of the door 20, the width of the display unit 30 can be increased, thereby providing a larger screen to the user.

As in the prior art, the form in which the display is installed on the door increases in price when the size of the display becomes larger, but affects the shape of the heat insulating material filled in the door because the space occupied by the display becomes larger. Therefore, there is a limit to the size of the display.

However, in the present invention, since the display unit 30 is not an electric device, the display unit 30 can be extended to the same width as the door 20.

The image providing unit 100 may be connected to the user terminal 200 through a wireless network so that an image provided from the user terminal 200 may be displayed on the display unit 30 through the image providing unit 100 have.

Meanwhile, the cabinet 10 may be provided with a storage room in which foods are stored and a machine room in which a compressor capable of compressing the refrigerant is provided. And cold air can be supplied to the storage compartment by a refrigeration cycle driven through the compressor.
