AIR CONDITIONER AND CONTROL METHOD THEREOF

摘要

An air conditioner for determining whether a human body exists in a sensing region using a plurality of heat sensors, as human body-detecting sensors, installed in the air conditioner and arranged at regular intervals. The air conditioner recognizing, when a human body has been detected, angles formed between the human body-detecting sensors and the human body, and calculating a distance from the human body-detecting sensors to the human body based on the recognized angles and a distance between the human body-detecting sensors, and adjusting a direction and speed of wind according to the calculated distance to the human body, and a control method of the air conditioner. Also, the air conditioner may be used as a security sensor when it does not operate.

主权项

1. An air conditioner comprising:
a plurality of human body-detecting sensors configured to detect a human body; a blade configured to change a direction of wind; a blow fan configured to change a speed of wind; and a controller configured to perform a first sensing mode for detecting a human body, to perform a second sensing mode in which a narrower region than in the first sensing mode is monitored when a human body has been detected, and to adjust, when a human body has been detected in the second sensing mode, a direction and speed of wind according to a direction in which the human body is positioned and a distance from the human body-detecting sensors to the human body.
