<First invention> The air outlet area adjusting device opens the air outlet so that the opening area becomes large during the drying operation. Therefore, the air blown from the air outlet into the bathroom is blown out evenly over a wide area in the room. Since the blowing air velocity is relatively low, the air flow that is subsequently sucked in through the suction port and circulated in the bathroom acts so as to be centered on the upper portion where the material to be dried is suspended. Therefore, since the drying air from the dryer is concentratedly sent to the material to be dried hung near the ceiling in the bathroom, unevenness in dryness is reduced and the drying efficiency is improved.

Further, during the heating operation, a part of the air outlet is closed so that the air outlet area becomes smaller, so that the speed of the air blown from the air outlet is increased, and the hot air reaches the lower part of the bathroom. To do. Therefore, the heating effect near the floor of the bathroom can be enhanced.

<Second Invention> In addition to the above-mentioned configuration, the variable air flow direction louver device sequentially changes the blowout direction of the blown air during the drying operation, so that the object to be dried hung near the ceiling part in the bathroom from above. It works so that the dry air that is sent can be uniformly hit from each direction. Therefore, unevenness in dryness is further reduced and the drying efficiency is improved.
