Abstract
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.
Claims19
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.
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;
- a liquid crystal unit configured to block or transmit rays emitted from a human body;
- a current applying unit configured to apply current to the liquid crystal unit or to block current that is applied to the liquid crystal unit;
- 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.
A control method of an air conditioner, comprising:
- determining whether a human body exists in a first sensing region;
- when a human body has been detected in the first sensing region, determining whether a human body exists in a second sensing region having a narrower width than that of the first sensing region;
- and
- when a human body has been detected in the second sensing region, setting 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.
A control method of an air conditioner, comprising;
- at a liquid crystal unit, blockings or transmitting rays emitted from a human body;
- at a current applying unit, applying current to the liquid crystal unit or blocking current that is applied to the liquid crystal unit;
- determining whether a human body exists in a first sensing region in a first sensing mode;
- switching the first sensing mode to a second sensing mode when a human body has been detected, the second sensing mode in which a narrower region than in the first sensing mode is monitored;
- when a human body has been detected in the second sensing mode, recognizing a direction in which the human body is positioned and calculating a distance to the human body;
- and
- setting a direction and speed of wind according to the direction in which the human body is positioned and the distance to the human body.
