Abstract

PURPOSE:To send an air flow to all inhabitants and thereby improve comfortableness by detecting the distribution of positions of the inhabitants from outputs received from a human body position distribution sensor, by conducting a right/left swing at least and by computing the width of the swing. CONSTITUTION:When a plurality of positions of human bodies are discriminated by a human body position distribution detecting sensor 1, the width of the distribution of persons is computed. Then, the width of a swing is computed so that an air flow is sent to all inhabitants, and based on the result of this computation, right and left air direction deflecting driving means 4a and 4b are controlled. As for detection of the human bodies, a plurality of sensors detecting IR rays radiating from a moving body to be detected, such as the human body, are provided along the direction of movement of the body to be detected and thereby the direction of movement of the body is detected. Detecting beams for the discrete sensors are made to overlap each other and also set in a sequential arrangement so that the end parts of the detecting beams are in parallel practically with each other, and detecting areas of the discrete sensors are set in an area traversing the areas wherein the detecting beams overlap each other.

Description

The wind direction control device of this air conditioner, especially during heating, based on the signal from the human body detection sensor,
When determining which zone in the room the person is, and the temperature of the blown air detected by the blowout temperature sensor is less than a predetermined reference value, the wind direction control device is in the zone where it is determined that there is a person. When the blowing temperature from the indoor unit is controlled by the control means so that it does not go out, and the blowing temperature is above the reference value, the wind direction control device controls the blowing air to go to the zone where it is determined that there is a person by the controlling means. By doing so, the cold air does not hit the occupants directly in any zone, and the warm air can be directly applied to the occupants in any zone to obtain the heating feeling effectively.
