Claims

A fan that blows air,
An up and down wind direction plate that is divided into left and right and adjusts the vertical direction of the wind from the fan;
A first control for fixing an angle of the left and right wind direction plates on the left side with respect to the horizontal direction at an angle smaller than an angle of the right and left wind direction plates on the right side with respect to the horizontal direction; A blower comprising: a control unit that alternately repeats a second control that is fixed at an angle larger than the angle of the upper and lower wind direction plates on the right side with respect to the direction.

The blower according to claim 1, wherein the control unit switches the first control and the second control at regular intervals.

The upper and lower wind direction plates on the left side and the right side are provided in two in the vertical direction,
In the first control, the control unit fixes the angle of the upper and lower wind direction plates on the upper left side with respect to the horizontal direction at a smaller angle than the angle of the upper and lower wind direction plates on the upper right side with respect to the horizontal direction and lower left with respect to the horizontal direction. The angle of the vertical wind direction plate on the side is fixed at an angle smaller than the angle of the vertical wind direction plate on the lower right side with respect to the horizontal direction. In the second control, the angle of the upper and lower wind direction plate on the upper left side with respect to the horizontal direction is fixed. The angle of the upper and lower wind direction plates on the upper right side with respect to the horizontal direction is fixed at an angle larger than the angle of the upper and lower wind direction plates on the lower left side with respect to the horizontal direction and the angle of the upper and lower wind direction plates on the lower right side with respect to the horizontal direction. The blower according to claim 1 or 2, wherein the blower is fixed at a large angle.

In the first control, the control unit is configured such that an angle of the upper and lower wind direction plate on the lower left side with respect to a horizontal direction is set such that a tip of the upper and lower wind direction plate on the lower left side is lower than a tip of the upper and lower wind direction plate on the upper right side. In the second control, the angle of the upper and lower wind direction plates on the upper left side with respect to the horizontal direction is set such that the tip of the upper and lower wind direction plates on the upper left side is positioned higher than the tip of the upper and lower wind direction plates on the lower right side. The blower according to claim 3, wherein the blower is fixed at an angle.

Left and right wind direction plates that are provided on the left and right, respectively, and adjust the direction of the wind from the fan in the left and right direction;
A sensor for detecting the position where the human body exists,
The blower according to any one of claims 1 to 4, wherein the control unit adjusts directions of the left and right wind direction plates on the left side and the right side according to a position where a human body detected by the sensor exists .

When the position of the human body detected by the sensor is in the front direction, the control unit adjusts the direction of the left and right wind direction plates on the left side to the right side of the front direction, and sets the direction of the right and left wind direction plates on the right side to the front side. 6. The blower according to claim 5, wherein the blower is adjusted to the left side of the direction.

When the position of the human body detected by the sensor is on the left side of the front direction, the control unit adjusts the direction of the left and right wind direction plates on the left side to the left side of the front direction or the front direction, and The blower according to claim 5 or 6, wherein the direction of the wind direction plate is adjusted to the left side from the direction of the left and right wind direction plates on the left side.

When the position where the human body detected by the sensor is on the right side of the front direction, the control unit adjusts the direction of the right and left wind direction plates on the right side to the right side of the front direction or the front direction, and The blower according to any one of claims 5 to 7, wherein the direction of the wind direction plate is adjusted to the right side from the direction of the right and left wind direction plates on the right side.

When the position where a plurality of human bodies are present is detected by the sensor, the control unit detects the left and right wind directions on the left side and the right side according to the position where the leftmost human body exists among the positions where the plurality of human bodies exist. A third control for adjusting the direction of the board, and a fourth control for adjusting the direction of the left and right wind direction plates on the left side and the right side according to the position where the rightmost human body exists among the positions where the plurality of human bodies exist Are repeated alternately, The air blower in any one of Claim 5 to 8 characterized by the above-mentioned.

The blower according to claim 9, wherein the control unit switches between the third control and the fourth control at regular intervals.

The control unit performs the first control and the second control once while performing the third control once, and performs the first control and the second control while performing the fourth control once. The blower according to claim 9 or 10, wherein two controls are performed once.

When the position at which a plurality of human bodies are present is detected by the sensor, the control unit sequentially selects each of the positions at which the plurality of human bodies are present , and depending on the position at which the selected human body is present , The blower according to any one of claims 5 to 8, wherein the fifth control for adjusting the direction of the right and left wind direction plates on the right side is repeated.

The blower according to claim 12, wherein the controller performs the first control and the second control once while performing the fifth control once.

A fan motor for driving the fan;
When the control unit performs the first control and the second control, the wind speed of the fan is changed to a sinusoidal waveform pattern and the waveform pattern for each period of the waveform pattern. Controlling the fan motor so as to change with time in a composite pattern including a plurality of patterns including a mountain-shaped variation pattern having a width of less than ¼ period and a height equal to or greater than the amplitude of the waveform pattern. The blower according to any one of claims 1 to 13.

In a blower control method comprising: a fan that blows air; and a vertical wind direction plate that is divided into left and right and adjusts the vertical direction of wind from the fan,
