When the mode switch 9 is pressed again,
The mode is switched from the front blowing mode to the spot blowing mode, the LED 10 displaying the front blowing mode is turned off, the LED 11 displaying the spot blowing mode is turned on, and the first wind direction changer 20 is moved from the fully closed position (FIG. 5) to the fully opened position. The swinging is repeated around the state of FIG. 9 in a smaller range until (FIG. 6).

[0035] Thus, the dehumidified air can be intensively blown out in a predetermined upper range, and the dehumidified air can be efficiently discharged when the laundry is dried and concentrated in this range (upper part of the main body). To dry efficiently.

At this time, if the second wind direction change body 21 is closed, the dehumidified air is less likely to leak forward, and the laundry can be dried more efficiently.

When the mode changeover switch 9 is further pressed again, the mode is switched from the spot blowing mode to the wide blowing mode, and LE for displaying the spot blowing mode is displayed.
LE that turns off D11 and displays wide balloon mode
While D12 is turned on, the first wind direction changer 20 repeatedly swings from the fully closed position (FIG. 5) to the fully opened position (FIG. 6).

At this time, if the second wind direction changing member 21 is rotated to a position where it blows obliquely downward as shown in FIG. (Here, about 180 degrees), the dehumidified air can be blown out, and the dehumidified air can be blown out over a wider range. As a result, as shown in FIG.
Even if you dry 2, 63, 64, laundry 61, 62, 63,
64 can be exposed to dehumidified air, and can be dried uniformly and in a short time.

When the second wind direction changing member 21 is closed, it is also possible to blow out the air from the diagonally upper part on the front side 5a to the diagonally rear part on the rear side 5b. Thereby, when there is no laundry on the front side 5a and there is laundry on the upper side, the dehumidified air can be efficiently applied and drying can be performed efficiently.

When the mode switch 9 is pressed again, the oscillating first wind direction changer 20 is stopped at an arbitrary position when the mode switch 9 is pressed. This allows the dehumidified air to be blown out in the direction desired by the user.

As described above, the air outlet 16 is formed from the upper surface 5c of the main body case 5 to the upper part of the front surface 5a, and the first wind direction changing member 20 which opens and closes the upper surface is formed around the air outlet 16.
And the second wind direction changing member 21 that opens and closes the front face 5a is pivotally supported so that air dehumidified in a wide range (A in FIG. 10) from the lower side of the front face 5a to the obliquely upper side of the back face 5b. Can be blown out. Therefore, even if the laundry 61, 62, 63, 64 is widely dried as shown in FIG. 10, the laundry 61, 62, 63, 64 can be dried by applying dehumidified air to the entire laundry. Thing 6
Drying unevenness of 1, 62, 63, 64 hardly occurs, and drying can be efficiently performed in a short time.

Further, since the first wind direction changing body 20 and the second wind direction changing body 21 can swing independently, the second wind direction changing body 21 is closed and the first wind direction changing body 20 is swung. In this case, the amount of dehumidified air leaking to the front face 5a side can be reduced, and a decrease in the amount of air blown obliquely upward from the front face 5a side toward obliquely upward to the back face 5b side can be suppressed. Therefore, when the laundry is dried and dried (for example, at the positions of the laundry 62, 63, and 64), the laundry can be efficiently dried.

When the first wind direction change body 20 is closed and the second wind direction change body 21 is rotated in a desired direction on the front face 5a side, the second wind direction change body 21 dehumidifies the front face 5a side. The concentrated air can be blown out.

Further, only the first wind direction changing member 20 is swung by the stepping motor 28 and the second wind direction changing member 21 is manually rotated. , The dehumidified air can be blown out in a wide range between the upper side and the rear side 5b.

Further, by using the stepping motor 28 as the driving means for swinging the first wind direction changing body 20,
By changing the command pulse, the first wind direction changing body 20 can be easily formed.
The swinging angle and range of the can be changed. Therefore, the direction and range in which the dehumidified air is blown out can be changed in various ways, and the usability can be improved.

Further, the wings 22a, 2a of the first
When the first wind direction changing body 20 is closed, the air dehumidified by the wings 22a and 23a can be smoothly guided to the second wind direction changing body 21 when the first wind direction changing body 20 is closed.

In the above embodiment, the outlet 16 is formed from the upper surface 5c of the main body case 5 to the upper part of the front surface 5a. However, the upper surface 5c of the main body case 5 and the surface adjacent to the upper surface 5c (side surface and back surface 5b). May be formed over the upper part of.

An intake port 15 is formed on the side opposite to the second wind direction changing member 21 so that the dehumidified air blown out from the outlet 16 is not directly directed to the intake port 15 but is sufficiently diffused after the air is sufficiently diffused. Although it is desirable that the air be taken in from the air inlet 15, the air inlet 15 may be formed on the side of the second airflow direction changing body 21 or on the side of the main body case 5.
