An indication device for a refrigerator includes an indicator light or a plurality of indicator lights indicating synchronously, a first detection unit configured to detect an object activity situation around the refrigerator, a second detection unit configured to detect an open/closed state of at least one door body of the refrigerator, and a processor. The processor is communicatively connected to the first detection unit, the second detection unit, and the indicator light to be adapted to control the indicator light to indicate a first state or a second state, according to detection results of the first detection unit and the second detection unit. The first state is different than the second state. A corresponding refrigerator includes a number of indicative elements and related indication states on a surface of a refrigerator panel which are simplified, but ensure sufficient coverage of various sensing functions and improve user satisfaction.
