In the above construction, the embodiment of the present invention will be described with reference to the accompanying drawings. The shaft 143 of the electric motor 14 which is a stepping motor is shaped like the shaft of the wind direction changing plate 13 as shown in FIG. The shaft 143 is formed by fitting one or two surfaces of the cylinder to be flat or polygonal, and the one or two surfaces of the cylinder to be flat. In this case, since the cross-sectional shape becomes substantially D-shaped or substantially elliptical, the connecting portion 131 of the wind direction changing plate 13 is provided with a concave portion having the above-mentioned shape so that the rotation of the electric motor 14 is transmitted without slipping. Has become. Connection part 13 of shaft 143 and wind direction change plate 13
The first fitting portion is covered by a bearing 15 fixed to a mounting plate 17. The gap between the bearing 15 and the electric motor 14 is covered with a water-repellent sealant 16 such as silicon or grease.
The structure is such that water vapor and water droplets do not enter through the gap between the motor and the motor 14. Also, the exterior 144 of the motor 14 itself
Is made of resin and has no gap, and there is no gap except around the shaft 143 which is the movable portion, so that water vapor, water droplets and the like do not enter the motor 14.

The bathroom heater / dryer 1 is mounted on a wall surface in the bathroom to heat and dry the bathroom.
If the motor 14 that rotates the motor 3 does not have a waterproof function, the motor 14 may cause corrosion inside and cause a failure. Therefore, the electric motor 14 is required to have waterproof performance that does not allow water vapor, water droplets, and the like to enter.

According to a fifth aspect, in the electric motor 14 such as a stepping motor, the winding 14
In the state where power is supplied to 1, the temperature of the motor itself rises due to the heat generated by the power supply and the temperature of the air inside the motor 14 also rises, so that the air pressure becomes higher than the outside. Further, since the air inside the electric motor 14 dries as the temperature rises, the dry air with a positive pressure inside the electric motor is not replaced with the moist air outside. Usually, the heat is generated with rotation, so that it is necessary to constantly move the wind direction changing plate.
As described in the above description, it is possible to generate heat by energizing without rotating, and in an environment where power is supplied by connecting to an outlet, energizing and generating heat without rotating to reduce the temperature of the motor 14 By doing so, a control method having a waterproof performance of preventing inhalation of water vapor and water droplets can be achieved. The non-rotational heat can be generated by applying a low voltage or low current that does not rotate, or by installing a heating element such as a heating wire near the electric motor, except for the stepping motor. Alternatively, when a low current is applied, the amount of heat generated is small and the temperature is unlikely to rise, so that the waterproof effect is insufficient. If a heating element is separately provided, there are problems such as installation space and cost.

Next, the operation of the embodiment of claim 7 including claim 6 will be described. When the user presses the wind direction change plate drive switch 21 in the remote control device 2 in FIG. The drive signal is sent to the motor 1, and the control unit 19 sends a drive signal to the motor 14 of the stepping motor.
In FIG. 4, when not in use, the closed position 13c for preventing water droplets and dust from entering the interior is provided.
, And once opened to the minimum open position 13b, while rotating the blower 18, the maximum open position 13a
The predetermined time (here, 1 second) is set to the maximum open position 13a.
And then return to the minimum open position 13b, the minimum open position 1
Also in 3b, it waits for a predetermined time in the same manner as described above, and moves to the maximum open position 13a again. The reciprocating motion between the minimum opening position 13b and the maximum opening position 13a is repeated. Starting from the minimum open position 13b of the reciprocating motion and returning to the minimum open position 13b is defined as one cycle. The time of one cycle can be varied by changing the time for moving one step. Here, one cycle of the predetermined time is limited to 10 seconds. By repeating the reciprocating motion of the wind direction change plate 13 described above, the wind direction of the wind generated by the blower 18 changes, and when the minimum open position 13b is at the minimum open position 13b, the laundry 6b near the bathroom heating / drying machine 1 like hot air 7b And at the maximum open position 13a, the wind is discharged to the laundry 6a near the facing wall 3b like the hot air 7a and dried.
