Furthermore, since the sensor holding body 27 is rotatably mounted at the central portion of the lower louver 16c, the sensor holding body 27 performs substantially the same function as the left and right fins 25.

Further, since the wind direction changing device 15 is incorporated in the louver holding casing 5 constituting the air outlet chamber 3, the operation of the wind direction changing device 15 cannot be confirmed unless it is a commercial dehumidifier. It has become possible to confirm the operation of the louver holding casing 5 incorporating the device 15 alone.
Further, the fin driving motor 30 is rotationally driven to rotate the sensor holding body 27, and the infrared sensor 28 provided in the sensor holding body 27 is also rotated. An interlocking arm 32 is provided by a reciprocating motion of an interlocking arm 32 that is provided below the back side of the sensor holding body 27 and that is pivotally connected to the connecting protrusion 37. Since the plurality of left and right fins 25 that are rotatably connected to the back side follow the left and right directions, the directions of the infrared sensor 28 and the left and right fins 25 are the same, and the dehumidified air is applied to the laundry captured by the infrared sensor 28. Can be blown out accurately.
