Under the situation that damper regulator 50 moves to the position shown in Figure 18 from centre position shown in Figure 17, drive stepper motor 101 with common speed, but also can with above-mentioned driven at low speed when initial equally.
When halted state, set each pattern through the operation of operating portion 180, then with damper regulator 50 in the position shown in Figure 18 as benchmark, control device 300 control step motors 101 make damper regulator 50 move to assigned position.
(ventilation in 24 hours)
Under the situation (situation of stop mode) that damper regulator 50 moves to the position shown in Figure 18; Set ventilation in 24 hours (ventilation often) through the operation of operating portion 18; Then with damper regulator 50 in the position shown in Figure 18 as benchmark; Control device 300 control step motors 101 make damper regulator 50 move to position shown in Figure 3, and CD-ROM drive motor M makes pressure fan 40 rotations.
When damper regulator 50 moved, with above-mentioned same, output was moved the more umber of pulse of required umber of pulse than being used for to the position of Fig. 3, and the leading section 50a of damper regulator 50 is connected in the edge portion of blow-off outlet 26.At this moment, as stated,, make the leading section 50a of damper regulator 50 be connected to the edge portion of blow-off outlet 26 reliably, and do not receive the influence of backlash through the higher umber of pulse of output.
In addition, when damper regulator 50 moves, the starting stage with driven at low speed stepper motor 101, after this drive with common speed.Thereby, even damper regulator 50 since dust etc. when being fastened on the position shown in Figure 18, also can rotating reliably and move damper regulator 50.
If damper regulator 50 moves to position shown in Figure 3; Pressure fan 40 rotations; Then shown in arrow О by the air in air entry 25 suction bathrooms 12, and shown in arrow Q, be disposed to the outside from exhaust outlet 28 through air supply path 27; Thereby carry out the ventilation in bathroom 12, can also take a breath to other room through this bathroom 12.
Under the situation of carrying out ventilation in 24 hours, set the rotational time of pressure fan, building was whenever once taken a breath at a distance from 2 hours.
As stated, when damper regulator 50 is moved in rotation, the starting stage with low speed rotation stepper motor 101, after this with common speed rotary step motor 101, damper regulator 50 is moved rapidly to assigned position.
In addition; As shown in Figure 7; The two ends of the axial region 114 of reduction gearing 110 are supported between the sidewall 23S of push part 160 and damper regulator chamber 23 freely rotationally, thereby, when stepper motor 101 drives; Reduction gearing 110 can not moved from driven wheel 103, thereby can the driving torque of stepper motor 101 fully be passed to reduction gearing 110.
