초록

The present invention discloses a refrigerator which can precisely adjust and display not only an ice making and storing amount but also an ice dispensing amount. As an ice level sensing unit provided at an ice storage unit for storing ice senses the ice storage amount by light, it is possible to adjust and display the ice storage amount. Moreover, as an ice sensing unit provided at an ice guide unit for dispensing ice senses the ice dispensing amount by light, it is possible to adjust and display the ice dispensing amount.
