Abstract: Air-blowing from a second air outlet is effectively used. An air conditioner includes a main body unit and an auxiliary housing. The main body unit forms a first air outlet which blows out a cool or warm airflow. The auxiliary housing is attached to at least one side of the first air outlet to be freely movable, and forms a second air outlet which blows out taken-in indoor air. A control circuit blows out the indoor air from the second air outlet at a wind speed which is higher than the wind speed of cool air or warm air that is blown out of the first air outlet.

Abstract: An aspect of the present invention relates to an air conditioner which is provided with a structural body, a wind direction plate, and auxiliary housings. The structural body forms an air outlet that extends in a horizontal direction and blows out a cool or warm airflow which is generated by a heat exchanger on a downward-facing surface which is continuous downward from a front surface, and includes one pair of wall bodies which are fixed to be immovable with respect to the air outlet on both sides of the first air outlet. The wind direction plate is disposed in the air outlet and is supported by the structural body to be freely rotatable around a horizontal shaft line. The auxiliary housings are attached to an outer wall surface of the wall body to be freely rotatable around a horizontal shaft on both sides of the air outlet, and form an auxiliary air outlet which blows out taken-in indoor air.

Abstract: A first fan controlling section of a controller circuit is configured to control a first blower fan so as to induce the discharge of the airflow of a cool air through a first air outlet defined in a first enclosure of an indoor unit of the air conditioner. A second fan controlling section is configured to control second blower fans so as to induce the discharge of the airflows of a room air through second air outlets, respectively, defined in a pair of second enclosures disposed on the opposite sides of the first enclosure. An enclosure attitude controlling section is configured to change the respective attitude of the second enclosures relative to the first enclosure.

The auxiliary housing is attached to at least one side of the first air outlet to be freely movable, and forms a second air outlet which blows out taken-in indoor air. A control circuit controls a second wind direction plate so that a second reference plane PL2 which regulates a wind direction of the second wind direction plate intersects a first reference plane PL1 which regulates a wind direction of a first wind direction plate, on a downstream side of the airflow.

Abstract: An air conditioner includes a main unit having an enclosure defining an air outlet. The enclosure contains a heat exchanger generating a cool air or a warm air forming airflow running out of the air outlet. A pair of fan units are disposed on the opposite sides of the air outlet. The fan units are configured to suck a room air and to blow the room air. The airflow of the room air can be utilized to control the direction and/or movement of the airflow of the cool air or the warm air. The cool air or the warm air can be conveyed to desired locations.

Abstract: There is provided an electric dust collection device which can effectively capture fine particles while avoiding a pressure loss. The electric dust collection device is provided with a charging electrode, a dust collection electrode, and a repulsive electrode. Along a flowing direction of an airflow, the dust collection electrode is disposed downstream of the charging electrode, and the repulsive electrode is disposed downstream of the dust collection electrode. The dust collection electrode is formed of a conductive material which partitions a ventilation passage through the airflow pass in the flowing direction. The repulsive electrode forms an electric barrier which has the same polarity as that of the charging electrode with a posture that intersects the airflow in the flowing direction.
