A control unit for controlling the motor of the blower unit and controlling the left / right swing of the blower unit is provided.
The control unit controls so that the wind speed at the position closer to the center is smaller than the wind speed at the position near both ends in the left and right swing of the blower unit .
The ventilation and left / right swing of the ventilation unit are controlled by switching to a plurality of types of ventilation modes.
The multiple types of ventilation modes are
A continuous mode in which the blower is swung left and right at a predetermined speed while controlling the motor so that the wind speed is constant.
The left and right swings of the blower are performed at a speed lower than the predetermined speed while controlling the motor so that the wind speed at the position closer to the center is smaller than the wind speed at the positions near both ends in the left and right swing of the blower. Equipped with a clothes drying mode
Blower. The blower according to claim 1, wherein the wind speed adjustment range can be set in a plurality of stages with the wind speed at the position near both ends of the left and right swing of the blower as the upper limit and the wind speed at the position near the center as the lower limit. The blower according to claim 1 or 2, wherein the swing width of the left and right swing of the blower portion can be adjusted to a plurality of set angle ranges. The wind speed increase / decrease range is set from the upper limit of the wind speed at the position near both ends of the left / right swing of the blower to the lower limit of the wind speed at the position near the center corresponding to each set angle range of the left / right swing of the blower. The blower according to claim 3. Equipped with a stepping motor that drives the left and right swing of the blower
The blower according to any one of claims 1 to 4, wherein the control unit controls the left-right swing of the blower unit by a pulse signal sent to the stepping motor. The blower portion has a DC motor for driving the fan.
The blower according to claim 5, wherein the control unit controls the DC motor in response to a left-right swing of the blower unit by the stepping motor. 6. The blower described. The blower according to any one of claims 1 to 7, further comprising a detection unit for detecting that the left and right swing position of the blower unit is a predetermined position. Equipped with a stepping motor that drives the vertical swing of the blower

The one according to any one of claims 1 to 8, wherein the control unit controls the wind speed at a position closer to the upper end than the wind speed at a position closer to the lower end in the vertical swing of the blower unit. Blower. The blower according to claim 9 or 10, wherein the control unit controls the blower unit to return to a reference posture facing a horizontal direction when the vertical swing of the blower unit is stopped and when the power is turned off. The blower unit includes a distance detecting means for detecting the distance to the blower object in the blower direction.
The blower according to any one of claims 1 to 11, wherein the control unit controls the motor and swing of the blower unit based on the distance detection information detected by the distance detection means. A fan for blowing air, a fan that can swing up and down and a fan that can swing left and right, and a fan that has a motor to drive the fan.
A control unit for controlling the motor of the blower unit and controlling the vertical swing and the left / right swing of the blower unit is provided.
A temperature sensor is mounted on the air blower.
It is configured to determine the cooling operation or the heating operation of the air conditioner based on the temperature information detected by the temperature sensor.
