DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for cooling, dehumidifying or heating a room.

[0002]

2. Description of the Related Art Conventionally, in an indoor unit of an air conditioner, air conditioned air is blown out from a blowout port, and the blowout direction is automatically adjusted to an arbitrary angle in a vertical or horizontal direction by a wind direction changing blade provided in the blowout port. Or, by aiming manually, the room temperature distribution is made uniform or proper, and the comfort is improved by not directly applying the airflow. Alternatively, there is a type in which a plurality of outlets are provided in advance to diffuse the blown air. In such a type, a ceiling embedded cassette type in which air is blown from the ceiling in four directions, or a wall, ceiling, or floor surface installed on the floor There is a floor-standing type that blows air in the direction. For example, as shown in Japanese Patent Application Laid-Open No. 3-59325, the configuration is as shown in FIG.

FIG. 9 is a front sectional view of a conventional air conditioner. A heat exchanger 22 is arranged inside the air conditioner main body 21, and a centrifugal fan 23 a is arranged on the leeward side of the heat exchanger 22 on the upper side and a centrifugal fan 23 b on the lower side. When the centrifugal fans 23a and 23b are rotating, air flows in from the suction port 24 on the side surface, heat is exchanged through the heat exchanger 22, and flows to the outlet 26 through the flow path composed of the casing 25a or 25b. The air flows and acts as a blower. 27 is a water tray for treating condensed water.

Since the outlet 26 is inclined in the vertical direction, air is blown out at a wide angle, and according to an enlarged cross-sectional view of the blowout portion in FIG. . Since the air-conditioned air flows from the outlet along the wall surface, the air is hardly affected by the radiation from the wall surface, and furthermore, the inclination and the blades 28 of the outlet cause circulation and mixing of the indoor air, resulting in temperature unevenness. Can be eliminated.

[0005]

However, in the above-mentioned conventional structure, the temperature can be made uniform by the circulating airflow flowing through the room, but since air flows along the inner wall of the room, it becomes indirect air-conditioning, and the center of the living space is It takes time for air conditioning. In particular, during heating, air circulates and mixes with room temperature, leaving only airflow in the living space, and feels cold on the bodily sensation. In addition, since the density of the cold air is high, in this configuration, it is difficult to air-condition the ceiling surface where the heat radiation is large at the time of cooling.

Further, if a plurality of fans are in the same air flow path common to the suction port and the outlets are in different directions, even if the inside is separated by a shield or the like, the fans are connected from the upstream of the suction port. Operation control is very difficult due to inquiries of the air flow. The only way to avoid this is to increase the size of the air conditioner body 1 or separate the fans for each fan.

The present invention has been made to solve such a conventional problem. A first air flow path for performing air exchange by heat exchange and another air flow path for not performing heat exchange are provided. By making the outlets of the air flow paths adjacent to each other and setting the blowing direction to an arbitrary direction, it is possible to simultaneously improve the indoor thermal environment and the feeling of airflow, and to produce an integrated type without increasing the size. It is an object of the present invention to provide an air conditioner that can perform such operations.
