Abstract: A refrigerator includes a water sensor unit secured to a case to overlap with a lower surface of a water tank, so that the water level sensor unit may maintain a constant position and operational stability may be increased, regardless of whether the water tank is mounted or demounted, and the upper surface of the water level sensor unit is inclined toward the front surface of the water level sensor unit, thereby reducing an operational error due to residual water.

Abstract: A filter device for a refrigerator includes a switch, which detects whether a filter is installed, is turned on or off interlocking with rotation of a head cover, so that an operation for detecting whether the filter is completely installed and an operation for detecting a replacement completion signal of the filter can be synchronized with each other.
