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.

Controller circuit for air conditioner with cool air guided with room temperature airstream

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.

Room air conditioner with movable side fan units

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 heat exchanger includes a rear section having a length larger than that of a front section in the longitudinal direction of the air outlet. The rear section extends into at least one of spaces respectively defined behind the fan units.

Air conditioner

There are provided a first guide channelfor making a U-turn of a leading end of a filterat a front side of a main unit cabinetduring forward movement of the filterand a second guide channelfor drawing a rear end of the filter to a rear surface side of the main unit cabinetduring backward movement of the filter

Air conditioner with automatic air filter cleaner

A front panel constituted by a synthetic resin molded product is used with respect to a base panel, side panels, and a top panel which are formed of a metal, first retaining means for the side panels and second retaining means for the top panel are provided on the front panel to effect fixation.

Outdoor unit of air conditioner

In an air conditioner equipped with an air cleaner, a front panel is provided with three air inlets: a first air inlet located on the front face of the front panel, a second air inlet located on the top face thereof, and a third air inlet located therebetween. Each of the first and second air inlets has an opening/closing unit including louvers, and an air cleaner is arranged on the inside of the third air inlet. At the time of cooling/heating operation and at the time of dehumidifying operation, the first and second air inlets are opened and closed by the opening/closing unit, by which the amount of air passing through the air cleaner is changed, thereby utilizing the air cleaner effectively.

An air conditioner includes a housing to be mounted on a wall surface in the interior of a room, an air inlet provided at an upper part of the housing, an air outlet provided at a lower part of the housing, an air passage provided in said housing so as to connect the air inlet and said air outlet to each other, a heat exchanging means and an air blowing device disposed in said air passage, and a wind direction plate provided inside an opening of the air outlet in order to change the direction of blowing of thermoregulated air out of the air outlet. An air quantity adjusting plate is provided at an end of the opening of said air outlet in order to change the area of the opening of the air outlet, whereby a sufficient air quantity is obtained regardless of the direction of ventilation of thermoregulated air to thereby perform room air-conditioning efficiently.
