Air conditioner indoor unit with human body detection device and obstacle detection device for wind direction control

Abstract

A plurality of human position discriminating regions each include at least two obstacle position discriminating regions. If a determination is made that an obstacle is present in an obstacle position discriminating region belonging to or positioned in front of a human position discriminating region where a determination has been made that a person is present, a first air current control is conducted in which horizontal wind direction changing blades swing within at least one obstacle position discriminating region belonging to the human position discriminating region where the determination has been made that the person is present, or a second air current control is conducted in which the horizontal wind direction changing blades swing within at least one obstacle position discriminating region belonging to the human position discriminating region where the determination has been made that the person is present or a human position discriminating region adjacent to such human position discriminating region, and in which a time period for fixing the horizontal wind direction changing blades is provided at each end of a swing motion of the horizontal wind direction changing blades.

Description

technical field [0001] The present invention relates to an air conditioner having an indoor unit provided with a human body detection device for detecting the presence or absence of a person and an obstacle detection device for detecting the presence or absence of an obstacle, and more particularly relates to an indoor unit for A technology that efficiently sends air-conditioning air to an area where a person has been detected by a human detection device based on the position of an obstacle detected by an obstacle detection device. Background technique [0002] A conventional air conditioner has an indoor unit provided with a human detection device including a human detection sensor such as a pyroelectric infrared sensor and an ultrasonic sensor for detecting a distance to an object. In this air conditioner, by detecting the position and distance of a person in the room using a human detection device and then controlling the wind direction changing device composed of vertica...

AI Technical Summary

Problems solved by technology

[0003] In the air conditioner disclosed in Patent Document 1, if an area where no one exists coincides with an indoor area where obstacles such as furniture hindering the circulation of air-conditioning air exist, the air-conditioning air is sent toward the obstacle, thereby reducing the air-conditioning efficiency.
