のである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner of a ceiling installation type such as a ceiling mounted type or a ceiling suspended type.

調和機が普及してきている。2. Description of the Related Art In recent years, ceiling-mounted air conditioners, such as a ceiling-mounted type and a ceiling-suspended type, which perform cooling and heating by directly heating and cooling indoor air, have become widespread not only in stores but also in ordinary households.

くい傾向にある。そのため、暖房時において吹出方向を
下向きとすることが多い。[0003] In this ceiling-mounted type air conditioner, blown air is blown down from the vicinity of the ceiling. Generally, high-temperature air tends to rise because of its small density and lightness, and therefore is blown out during heating. Warm air tends not to reach near the floor. Therefore, the blowing direction is often downward during heating.

る、いわゆるショートサーキットが発生しやすくなる。[0004] As a result, in a ceiling-embedded type air conditioner in which a suction port is provided at the center of the decorative panel and air outlets are provided at four sides around the panel, a part of the air blown into the room is sufficient. The short circuit is easily sucked into the suction port without reaching the bottom.

なっている。[0005] This short circuit raises the intake air temperature during heating, lowers the temperature during cooling to increase the load on the system, lowers system efficiency, and uses a room temperature sensor installed at the suction port. Since the operation becomes inefficient, such as erroneous detection of the room temperature and the thermo-off, or the temperature-adjusted air flow drifting to make it difficult to reach a desired space, it is a major problem to reduce the operation.

Reference numeral 2 denotes a heat exchanger that exchanges heat between the refrigerant and indoor air, and 3 denotes a blower that blows air to the heat exchanger 2. The heat exchanger 2 and the blower 3 are housed inside the indoor unit 1.

の吹出方向を水平方向とする風向制御手段である。In FIG. 9, reference numeral 4 denotes a decorative panel provided on the lower surface of the indoor unit 1, reference numeral 5 denotes a filter or the like, and a suction port for sucking indoor air into the interior of the indoor unit 1 by a blower 3; An outlet that blows air that has been sucked in from the inlet 5 and heated or cooled by the heat exchanger 2 into a room, and 7 is a louver that can change the blowing direction of the air that is blown out from the blower 6 to a desired direction for each blower outlet. . 8 is
The airflow direction control means sets the blowout direction of the air blown from two opposing blowout ports downward, and sets at least one blowout direction of two adjacent blowout ports to the horizontal direction.
【００１１】以上のように構成された空気調和機につい
て、以下その動作を説明する。The operation of the air conditioner configured as described above will be described below.
【００１２】まず、空気調和機により暖房運転を開始す
ると、室内空気が送風機３により吸込口５から吸い込ま
れる。さらに、熱交換器２により加熱された温風は、吹
出口７により室内へ吹き出される。First, when a heating operation is started by the air conditioner, room air is sucked from the suction port 5 by the blower 3. Further, the warm air heated by the heat exchanger 2 is blown into the room by the blower outlet 7.
【００１３】一般的に、温度の高い空気は密度が小さい

吹き下ろす方式の空気調和機において、暖房運転時、高
温の吹出空気は床面に到達するまでに浮上してしまうた
め、過大な上下温度差が生じ、足元が寒く頭部が暑い不
快な環境となるという問題がある。In general, high-temperature air tends to rise because of its low density, and low-temperature air has a high density and tends to descend downward. Therefore, in an air conditioner that blows down air from the vicinity of the ceiling, during heating operation, high-temperature blown air floats before reaching the floor, resulting in an excessive vertical temperature difference, resulting in cold feet. There is a problem that the head becomes a hot and unpleasant environment.
【００１４】そのため、暖房時は、通常、吹出方向を下
向きとして用いることが多い。しかし、吸込口の周辺に
吹出口を設けた空気調和機においては、吹出方向を下向
きとしたときに吹出空気がそのまま吸込口に吸い込まれ
るショートサーキットが発生しやすくなる。Therefore, during heating, the blow-out direction is usually set to be downward. However, in an air conditioner provided with an outlet around the inlet, a short circuit in which the blown air is sucked into the inlet as it is when the blow direction is downward is likely to occur.
【００１５】ここで、風向制御手段８により、吹出口６
のうち相対する二つの吹出口から吹き出す空気の吹出方
向を下向きとし、残りの隣接する二つの吹出口のうち少
なくとも一つの吹出方向を水平方向とする。The air outlet 6 is controlled by the wind direction control means 8.
Out of the two opposing outlets is directed downward, and at least one of the remaining two adjacent outlets is directed horizontally.
【００１６】この結果、吹出口６のうち１方向から吹き
出す空気が水平方向となるので、その下方に吸込空気の
通り道ができ、ショートサーキットが緩和されることと
なる。As a result, the air blown out from one of the outlets 6 is in the horizontal direction, so that there is a passage for the sucked air below the air outlet, thereby alleviating the short circuit.

点があった。However, in the above-mentioned conventional configuration, the direction of air blown out from the two opposed outlets is directed downward by the wind direction control means 8, and at least one of the two adjacent outlets is blown. Since the blowout direction is horizontal, the hot air blown out rises near the ceiling in the direction of the horizontal outlet, and the warm air blows up to the living area and near the feet in that direction. , And there is a drawback that the living area in the direction of the air outlet and the vicinity of the foot are not sufficiently warmed.

る。The present invention has been made to solve the conventional problems, and in addition to being able to reduce the short circuit, it is also intended to make the warm air reach the area of the living area in more directions and the vicinity of the feet for more uniform temperature. It is to provide an air conditioner that can perform.

Thereby, since the blowing direction of the air blown out from the two facing outlets is downward, and at least one of the two adjacent outlets is the horizontal direction,
In the direction of the horizontal outlet, the hot air blown out rises to the vicinity of the ceiling, and the hot air cannot reach the living area and the vicinity of the feet in that direction. There was a drawback that the living area in the direction of the outlet and the vicinity of the feet were not sufficiently warmed.

It is to provide an air conditioner that can be raised.

In addition to the above, the blowout blowout in the substantially horizontal direction and the blowout blowout in the circumferential direction can be reduced. Because it is arranged alternately, it is possible to improve the temperature uniformity in the horizontal plane by blowing the warm air at a downward angle toward four equal directions so that the warm air reaches the living area uniformly. Since the passage of the suction port can be formed in three equal directions, the circulating property of the airflow in the room is enhanced, and the temperature uniformity is improved.

温の吹出空気は床面に到達するまでに浮上してしまうた
め、過大な上下温度差が生じ、足元が寒く頭部が暑い不
快な環境となるという問題がある。In general, high-temperature air tends to rise because of its low density, and low-temperature air tends to have a high density and fall downward. Therefore, in an air conditioner that blows down air from the vicinity of the ceiling, during heating operation, high-temperature blown air floats before reaching the floor, resulting in an excessive vertical temperature difference, resulting in cold feet. There is a problem that the head becomes a hot and unpleasant environment.

ショートサーキットが発生しやすくなる。Therefore, during heating, the blow-out direction is usually set to be downward. However, in an air conditioner provided with an outlet around the inlet, when the blowout direction is downward, the outlet airflow surrounds the inlet 5, and the short-circuit in which the outlet air is sucked into the inlet as it is. Circuits are more likely to occur.
