According to such a configuration, by selecting the second mode, the warm air blows out toward the side wall of the bathroom through the swash plate type airflow direction changing device A, so that a person sitting in the bathroom and washing his body There is no danger of direct contact with hot air.

The output shaft of the motor 2 and the rotary shaft 1 are connected via a gear, and the rotary shaft 1 is slightly reciprocated in the extending direction by using, for example, a solenoid to rotate with the output shaft of the motor 2. When the gear that connects the shaft 1 can be disengaged, or the output shaft of the motor 2 and the rotary shaft 1 are directly connected to each other by providing an appropriate idling mechanism, the motor 2 rotates when the motor 2 is off. The shaft 1 may be freely rotatable. With this configuration, the motor 2 is turned off
When the bathroom heating clothes dryer AA is operated as described above, the rotary shaft 1 is maximally changed by the static pressure of the hot air blown out without detecting the rotational position of the rotary shaft 1 and controlling the motor 2 based on the detection. Held in a position rotated 90 ° from the position,
Warm air blows out just below. As a result, it is possible to shorten the drying time when a small amount of the object to be dried is hung just below the wind direction changing device A and dried, or when it is desired to preheat the washing floor before bathing in the winter. The time required for preheating can be shortened.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, in the bathroom heating clothes dryer AA described above, the swash plate type air direction changing device B may be used instead of the swash plate type air direction changing device A. In addition, when the forced exhaust device is already installed in the bathroom, the second section 201b from the bathroom heating clothes dryer AA
The exhaust multilayer disk fan fan 210 may be removed, and the exhaust intake port 210 and the exhaust port 211 may be closed. Further, instead of the warm-air circulating multilayer disc fan 203 and the exhaust multilayer disc fan fan 210, other types of fans such as a sirocco fan may be used. Further, the swash plate type airflow direction changing device according to the present invention can be used in a cooling and dehumidifying type bathroom clothes dryer using a refrigeration cycle.

As described above, in the present invention, the rotating shaft is installed between the centers of the opposite short sides of the rectangular warm air outlet, and the minor axis length of the swash plate is shorter than the short side length of the warm air outlet. If the swash plate is set to be slightly shorter and the straight notch edges of the swash plates at both ends are arranged close to the short side of the hot air outlet, the rotary shaft has the shortest diameter of the swash plate when the air outlet is viewed from the front. When it is in a rotation position that looks long, that is, when the wind direction change angle of the blown air by the swash plate is the maximum, when looking at the air outlet from the front, between the swash plate at both ends and the corner of the air outlet, No wide gap is formed. As a result, the airflow blows straight from the air outlet, collides with the airflow blown from the gap between the swash plates at the maximum change angle, and prevents the generation of the blown airflow of the intended maximum change angle, and blows it out again. A situation in which the directivity of the air flow is lost and the blown air flow is scattered is prevented. Further, in the wind direction changing device according to the present invention, the rotating shaft is installed between the centers of the short sides of the rectangular warm air outlet facing each other, and the minor axis length of the swash plate is slightly smaller than the short side length of the warm air outlet. If the short edge of the swash plate is placed close to the short side of the hot air outlet with respect to the arrangement of the swash plates of the shielding plate and the outer edge is arranged close to the short side of the hot air outlet, When it is in the rotation position that looks the longest, that is, when the swash plate maximizes the airflow direction change angle, the air outlets are viewed from the front and there is a gap between the swash plates at both ends and the corners of the air outlets. , No wide gap is formed. As a result, the air flow blows straight from the air outlet,
It collides with the airflow blown from the gap between the swash plates at the maximum change angle, prevents the generation of the blown airflow at the intended maximum change angle, and also loses the directivity of the blown airflow and scatters the blown airflow. The situation is prevented. Therefore, according to the present invention, a swash plate type airflow direction changing device can be provided in which the blown airflow having the intended maximum change angle can be reliably obtained and the blown airflow does not lose its directivity. Further, a bathroom heating clothes dryer including a heating source, a warm air circulation fan, and a casing that accommodates the heating source and the warm air circulation fan and has a rectangular warm air outlet and a circulation intake port formed therein. Further, by disposing the swash plate type airflow direction changing device according to the present invention, a bathroom heating clothes dryer having high drying efficiency is provided.
