  A water level detection device for detecting a water level of the water reservoir, which is provided in a water reservoir for storing water generated by operation of an electric device, and detects a water level of the water reservoir for driving a discharge means for discharging the water accumulated in the water reservoir. A first detector for detecting a low water level when the discharge means starts driving, a second detector for detecting a high water level when the water level is higher than the low water level, and an abnormal water level higher than the high water level. A water level detection device comprising a third detector for detection. The first floating body and the second floating body that move according to a change in the water level are provided, and the second detector and the third detector are combined with the different floating bodies, respectively. The water level detection device described. According to the detected water level, a water reservoir for accumulating drain water generated from the evaporator by the refrigeration cycle operation, a discharge means for discharging the drain water from the water reservoir, a water level detection device for detecting the water level of the water reservoir, and A control device that performs refrigeration cycle operation and drive control of the discharge means, and the water level detection device includes a first detector for detecting a low water level and a first detector for detecting a high water level higher than the low water level. 2 detectors and a third detector for detecting an abnormal water level higher than the high water level, and when the third detector detects an abnormal water level, the power supplied to the control device is turned off. An air conditioner characterized by that.
