Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner such as a fan and a control method therefor capable of accurately and optimally blowing air to a human body.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for security and air-conditioning control by detecting the presence or absence of people in a room and the amount of activity. That is, infrared rays are generated using an infrared sensor for the purpose of detecting the human body by detecting the infrared rays emitted from the human body and using the signal for controlling environmental control devices such as air conditioners and lighting equipment and crime prevention systems. Devices for detecting sources have come into use. Two types of infrared sensors are known: a quantum type sensor that captures infrared rays as photons, and a thermal type sensor that utilizes changes in the physical properties of the element that result from the temperature rise of the element due to absorption of infrared light. In general, a thermal sensor is used because it usually requires cooling with liquid nitrogen or the like. Among thermal sensors, the pyroelectric infrared sensor has a higher sensitivity than other sensors and is suitable for detecting the infrared source, but the pyroelectric infrared sensor basically detects changes in infrared rays. Therefore, when trying to detect a stationary infrared ray generation source, it is necessary to devise some kind of method so that the infrared rays intermittently enter the sensor light receiving part. The infrared rays are intermittently incident (chopping) by rotating or vibrating the chopper.

FIG. 7 shows a schematic view of a conventional fan as an air conditioner when viewed from the front. By using this fan and swinging the head of the fan around the slide pipe 73, it is possible to blow air to an area of about 120 ° in the horizontal direction. Therefore, if a person tries to hit the wind of a fan, he will enter this area and
During the swing cycle in the range of °, we will wait for the wind to come. In addition, the adjustment of the strength of the wind was operated by a person each time according to his or her preference.

[0004]

As described above, in the conventional fan, the fan can only be blown uniformly to a region within a certain range around the fan, not around the person. , Those who strongly desire air blowing may spend more time waiting for the wind to come during the long swing cycle of the fan. On the contrary, a person who does not want the wind may feel uncomfortable due to the wind. That is, the conventional fan has a problem that it is necessary for a person to change the swinging direction or direction of the fan to a desired direction by hand each time. In addition, the strength of the wind is troublesome to adjust by pushing a button by a person. That is, there is a problem in that the present fan cannot blow air according to a person's wish.

An object of the present invention is to provide an air conditioner capable of blowing air in accordance with a person's wish in consideration of such problems as the conventional fan.
