The refrigerator includes a voice recognition function using a proximity sensor. The refrigerator has input/output (I/O) management functions for foods stored therein. The refrigerator communicates with a peripheral device over a network. ## Claims ### Claim 1 A refrigerator comprising: a main body including a plurality of storage chambers; a display provided in the main body of the refrigerator; and at least one processor configured to: control the display to display a refrigerator map including a plurality of different images when a predetermined condition is satisfied, wherein each of the plurality of different images corresponds to a different one of the plurality of storage chambers and each of the plurality of images includes function information corresponding to the different one of the plurality of storage chambers, and in response to a touch input selecting the one of the plurality of different images: control the display to display the selected one of the plurality of different images which is enlarged, and display at least one setting icon to control the function information of the one of the plurality of storage chambers corresponding to the selected one of the plurality of different images. ### Claim 2 (depends on 1) The refrigerator as claimed in claim 1, further comprising: a sensor for detecting an opening or closing state of a refrigerator door, wherein, when the sensor detects the opening or closing state of the refrigerator door, the at least one processor is further configured to control the display to display the refrigerator map. ### Claim 3 (depends on 2) The refrigerator as claimed in claim 2, wherein, when the sensor detects the opening or closing state of the refrigerator door, the at least one processor is further configured to control the display to display the function information associated with maintaining a constant temperature. ### Claim 4 (depends on 1) The refrigerator as claimed in claim 1, wherein the at least one processor is further configured to control the display to display a refrigerator management screen image for visualizing a state of the refrigerator. ### Claim 5 (depends on 1) The refrigerator as claimed in claim 1, wherein the at least one processor is further configured to control the display to display a list of recommended foods per indoor temperature in the vicinity of the refrigerator map. ### Claim 6 (depends on 1) The refrigerator as claimed in claim 1, further comprising: a button located in a vicinity of the display. ### Claim 7 (depends on 1) The refrigerator as claimed in claim 1, further comprising: a voice input interface for inputting a voice command of a user, wherein the at least one processor is further configured to control the display to display a process for recognizing user voice commands collected by the voice input interface. ### Claim 8 (depends on 1) The refrigerator as claimed in claim 1, further comprising: a sensor for detecting presence of a user in a vicinity of the refrigerator, wherein the at least one processor is further configured to activate a voice input interface based on user approach information collected by the sensor. ### Claim 9 (depends on 1) The refrigerator of claim 1, wherein the plurality of different images included in the refrigerator map are displayed simultaneously.
