Embodiment Construction

[0090] According to the air conditioner of the first invention, the indoor unit is provided with an indoor fan for transporting the indoor air taken in, a wind direction changing flap for changing the direction of the air blown out from the outlet, and an obstacle detection device for detecting the presence of an obstacle. Air-conditioning operation is performed by controlling the wind direction changing fins based on the detection result of the obstacle detection device, wherein the wind direction changing fins have left and right wind direction changing fins for changing the direction of the air from the air outlet left and right, In addition, the obstacle detection device has an ultrasonic sensor, and when the indoor fan detects an obstacle by the obstacle detection device during operation, when the left and right wind direction changing blades face the detection direction of the ultrasonic sensor, The orientation of the lateral wind direction changing blade is changed to a ...

Abstract

The present invention provides an air conditioner, capable of accurately detecting position of an obstacle by reducing affect of airflow to the utmost when a distance between the air conditioner and the obstacle is detected by an ultrasonic sensor so as to improve comfortability. An indoor unit of the air conditioner is provided with an indoor fan for conveying sucked indoor air, wind direction changing fins for changing the direction of the air discharged from a blow-out port, and an obstacle detection device having the ultrasonic sensor for detecting whether or not there are obstacles, wherein the wind direction changing fins are controlled according to the detection result of the obstacle detection device. In addition, if left and right wind direction changing fins face to the detection direction of the ultrasonic sensor when the indoor unit is operated and the obstacle detection device detects obstacles, the facing directions of the left and right wind direction changing fins are changed to be different from the detection direction of the ultrasonic sensor.

Description

technical field [0001] The invention relates to an air conditioner in which an obstacle detection device for detecting whether there is an obstacle is installed in an indoor unit, and an air conditioner is controlled to change a wind direction according to the detection result of the obstacle detection device. Background technique [0002] In a conventional air conditioner, an indoor unit is provided with a human body detection device including a human body detection sensor such as a pyroelectric infrared sensor and an ultrasonic sensor for detecting a distance from an object. Air-conditioning wind is sent to an area where there are no people by controlling the wind direction changing means composed of the upper and lower fins and the left and right fins (for example, refer to Patent Document 1). [0003] In addition, in the air conditioner described in Patent Document 1, the following proposal is proposed: when there is an obstacle such as furniture that hinders the circula...
