Disclosed herein is a dehumidifier having a structure improved to detect whether a water container is installed on a main body and the water container is full with water.
A dehumidifier comprising a main body including a suction port and a discharge port, a heat exchanger in which a refrigerant configured to exchange heat with air introduced through the suction port circulates, a water container separably installed on the main body and configured to store condensate generated in a process in which the air introduced through the suction port exchanges heat with the refrigerant and a sensor module provided in the main body to detect whether the water container is installed on the main body and detect a water level of the water container.
