As the wheel button 210 is rotated by a predetermined rotation threshold in the left and right direction, the wind power may be adjusted in a number of steps.

Specifically, when the rotation threshold is set to 100 steps, the wind power may be finely adjusted from step 1 to step 100 by rotating the wheel button in the left and right direction.

In this case, it may be set to a higher level among a plurality of stages at once. For example, by rotating the wheel button at once, the drainage can be adjusted to 25 steps, 25 steps, 50 steps, 75 steps, and 100 steps among 100 steps.

The fine adjustment and the drainage adjustment will be described in more detail with reference to FIG. 3.

As shown in FIG. 3, the head unit 200 includes a wheel button 210, a control unit 220, a variable resistor 230, a motor 240, and a water drainage setting unit 250.
