Air conditioner

Abstract

Provided is an air conditioner, which is constituted such that a plurality of left and right blades disposed at the blowout ports of an indoor equipment can be controlled independently for a plurality of blocks, and such that the area to be air-conditioned is divided into a plurality of areas by a plurality of human body sensors, and which is equipped with a control device for controlling the left and right blades independently for the individual blocks in accordance with the reaction results of the human body sensors. On the basis of at least one of the area characteristics indicating the frequency, which is decided by accumulating the reaction results of the human body sensors a predetermined number of times and which indicates the presence of a person in each of the areas, the personal activity in the personal presence area, and the adjacency of the personal absence area to the personal presence area, the control device can control the left and right blades thereby to change the opening ratio of the blowout ports to the plural areas.

Description

technical field [0001] The present invention relates to an air conditioner provided with a human body detection sensor for detecting the presence or absence of a person in an indoor unit, and more particularly to an air conditioner that detects the position of a person in the room and controls the left and right wind directions of the wind blown from the indoor unit machine. Background technique [0002] A related art air conditioner has a structure in which a human body detection sensor provided in the indoor unit detects a person's area from a plurality of areas, controls a plurality of left and right blowing deflection units according to the detected plurality of areas, and controls the left and right blowing deflectors according to the detected plurality of areas. The shortest distance is selected among the detected distances, and the vertical blowing direction is controlled with respect to the shortest distance (for example, refer to Patent Document 1).

AI Technical Summary

Problems solved by technology

[0006] However, as for the air conditioner described in Patent Document 1, it is not enough to simply control a plurality of left and right blowing deflectors based on the detected left and right positions of a plurality of regions, and the air conditioning efficiency and the comfort of the occupants are not enough. room for improvement

[0007] In addition, in the air conditioner described in Patent Document 2, a plurality of left and right fins are arranged on the base in multiple areas, and the angle of the left and right fins and the base is changed as a whole, which has the problems of complicated structure and high cost.
