Abstract

A refrigerator and a home appliance, of which the exterior design can be changed without replacing an exterior panel by changing the exterior design using an electrophoretic display (EPD) panel. The refrigerator includes a storage compartment, a door for opening and closing the storage compartment, and including a door body and an electrophoretic display (EPD) panel located in front of the door body, and a processor for controlling the electrophoretic display panel to change color based on at least one of a user's selection or an operation state.

Claims (51)

1 . A refrigerator comprising:

a first door for opening and closing a first storage compartment;

a second door for opening and closing a second storage compartment;

a first door panel forming a front surface of the first door and including a first display panel;

a second door panel forming a front surface of the second door and including a second display panel;

a sensor configured to detect an operating state of the refrigerator;

a transceiver configured to communicate with an external device; and

a processor configured to control the first display panel and the second display panel,

wherein the processor is further configured to:

obtain information about a first color to be displayed on the first door through the transceiver and control the first display panel so that the first door is displayed in the first color,

obtain information about a second color to be displayed on the second door through the transceiver and control the second display panel so that the second door is displayed in the second color,

obtain a color change condition for changing at least one of the first color of the first door or the second color of the second door through the transceiver, the color change condition being related to the sensor detecting an abnormality in one of the operating state of the refrigerator, the first storage compartment, or the second storage compartment, and

control at least one of the first display panel or the second display panel to inform the operating state of the refrigerator based on the operating state of the refrigerator and the color change condition.

2 . The refrigerator of claim 1 , wherein the processor is further configured to:

control the first display panel and the second display panel so that the first door and the second door display different colors.

3 . The refrigerator of claim 1 , wherein the processor is further configured to:

control at least one of the first display panel or the second display panel to inform the operating state of the refrigerator by periodically alternating a color of the at least one of the first door or the second door.

4 . The refrigerator of claim 1 ,

wherein the first storage compartment includes a freezer compartment, and

wherein the second storage compartment includes a refrigerator compartment.

5 . The refrigerator of claim 4 , further comprising:

a transparent panel disposed in front of each of the first display panel and the second display panel.

6 . The refrigerator of claim 1 , wherein the first storage compartment and the first door are located above the second storage compartment and the second door.

7 . The refrigerator of claim 1 ,

wherein the operating state of the refrigerator includes an internal state of each of the first storage compartment and the second storage compartment, and

wherein the sensor is further configured to detect the internal state of each of the first storage compartment and the second storage compartment.

8 . The refrigerator of claim 1 , further comprising:

memory storing the information about the first color, the information about the second color, and the color change condition.

9 . The refrigerator of claim 1 , wherein the color change condition includes at least one color change condition selected to be activated among a plurality of color change conditions.

10 . The refrigerator of claim 1 , wherein the processor is further configured to:

obtain a user input through the transceiver to activate at least one of a plurality of color change conditions including the operating state of the refrigerator and external information,

control at least one of the first display panel or the second display panel to change at least one of the first color of the first door or the second color of the second door based on at least one activated color change condition,

based on the at least one activated color change condition including the external information, control at least one of the first display panel or the second display panel so that a color corresponding to the external information is displayed on at least one of the first door or the second door.

11 . The refrigerator of claim 1 , wherein the processor is further configured to:

change an appearance of at least one of the first display panel or the second display panel to inform the operating state of the refrigerator.

12 . The refrigerator of claim 11 , wherein the processor is further configured to:

change a color of at least one of the first display panel or the second display panel to inform the operating state of the refrigerator.

13 . The refrigerator of claim 11 , wherein the operating state includes a preset failure condition.

14 . A method of controlling a refrigerator including a first door for opening and closing a first storage compartment and being equipped with a first display panel, a second door for opening and closing a second storage compartment and being equipped with a second display panel, a sensor configured to detect an operating state of the refrigerator, and a transceiver configured to communicate with an external device, the method comprising:

obtaining, through the transceiver, information about a first color to be displayed on the first door and controlling the first display panel so that the first door is displayed in the first color;

obtaining, through the transceiver, information about a second color to be displayed on the second door and controlling the second display panel so that the second door is displayed in the second color;

obtaining, through the transceiver, a color change condition for changing at least one of the first color of the first door or the second color of the second door, the color change condition being related to the sensor detecting an abnormality in one of the operating state of the refrigerator, the first storage compartment, or the second storage compartment; and

controlling at least one of the first display panel or the second display panel to inform the operating state of the refrigerator based on the operating state of the refrigerator and the color change condition.

15 . The method of claim 14 , wherein the operating state of the refrigerator is informed by periodically alternating an appearance of the at least one of the first door or the second door.

16 . The method of claim 14 , wherein the first display panel and the second display panel are controlled so that the first door and the second door display different colors.

17 . The method of claim 14 , wherein the controlling of the at least one of the first display panel or the second display panel comprises:

changing an appearance of at least one of the first display panel or the second display panel to inform the operating state of the refrigerator.

18 . The method of claim 17 , wherein the changing of the appearance of at least one of the first display panel or the second display panel comprises:

changing a color of at least one of the first display panel or the second display panel to inform the operating state of the refrigerator.

19 . The method of claim 17 , wherein the operating state includes a preset failure condition.

20 . The method of claim 15 , wherein the operating state of the refrigerator is informed by periodically alternating a color of the at least one of the first door and or the second door.
