1. A water leakage detecting device, comprising:
- a base retaining water leaked from a tub;
a detector detecting whether leaked water is retained in the base;
a first signal generator outputting a signal, when the detector detects the leaked water;
a second signal generator outputting a signal, when the detector does not detect the leaked water; and
a controller deciding whether to drain the leaked water and determining whether the water leakage detecting device has a malfunction.

Abstract
A water leakage detecting device for effectively detecting water leakage and sensing malfunctions in the device is disclosed. The device includes a base retaining water leaked from a tub, a detector detecting whether leaked water is retained in the base, a first signal generator outputting a signal, when the detector detects the leaked water, a second signal generator outputting a signal, when the detector does not detect the leaked water, and a controller deciding whether to drain the leaked water and determining whether the water leakage detecting device has a malfunction.

11. A method for detecting water leakage, comprising:
-
detecting leaked water in a base;
outputting a first signal, when the leaked water is detected, and outputting a second signal, when the leaked water is not detected; and
deciding whether to drain the leaked water and determining whether the water leakage detecting device has a malfunction, depending upon the first signal and the second signal. - View Dependent Claims (12, 13, 14, 15, 16, 17)
