Embodiment Construction

[0048] Embodiments of the present invention will be described below with reference to the drawings.

[0049] (The overall structure of the air conditioner)

[0050] An air conditioner used in an ordinary home includes an outdoor unit and an indoor unit connected to each other through refrigerant piping, and Figures 1 to 4 The indoor unit of the air conditioner according to the first embodiment of the present invention is shown.

[0051] The indoor unit includes a main body 2 and a movable front panel (hereinafter simply referred to as a "front panel") 4 for opening and closing a front suction port 2a formed in the main body 2 . When the air conditioner is not in operation, the front panel 4 is kept in close contact with the main body 2 to close the front suction port 2a, and when the air conditioner is in operation, the front panel 4 is removed from the main body 2 to open the front suction port 2a. figure 1 and 2 Shows that the front suction port 2a has been closed by the...

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...
