Abstract
Disclosed is an indoor unit having a dust storage container in which dust removed from an air filter is stored, and a dust collecting box into which the dust in the dust storage container is transferred by utilizing an effect of blown air. The dust storage container is provided with a full condition detection means for detecting a dust full condition of the dust collecting box. The full condition detection means includes an LED and a phototransistor which are opposed to each other with a storage portion interposed therebetween. After a dust transfer operation which transfers the dust from the dust storage container to the dust collecting box, an intensity of light of the LED that has passed through the storage portion is detected by the phototransistor. If the detected light intensity is equal to or less than a set value, a full condition of the dust collecting box is detected.
