Description of the Related Art Conventionally, as an indoor unit of an air conditioner, a cross fin heat exchanger and a cross flow fan are arranged in a substantially rectangular casing mounted on a wall surface, and are provided below the casing. Some air-conditioning air is blown out from the air outlet. However, the indoor unit of the air conditioner has a drawback that it does not fit the interior of the room because the protrusion from the wall surface is large and the depth cannot be reduced. Therefore, the present applicant has manufactured an indoor unit of an air conditioner that can improve the interior characteristics of a room by reducing the thickness. The indoor unit of this air conditioner has a heat exchanger in which a shaft is disposed in the casing in the front-rear direction, and is disposed on the rear side of the heat exchanger in the casing, and receives air sucked from the front side with respect to the shaft. A turbo fan that blows outward in the radial direction. In the indoor unit of the air conditioner, as shown in FIG. 5, the casing 101 is provided with outlets 122 and 123 (only two are shown in FIG. 5) for blowing in four directions in the vertical and horizontal directions. . When the turbo fan of the indoor unit rotates, the air sucked from the inlet 101a on the front side is blown out from the outlets 122 and 123 to four directions. FIG. 6 is a cross-sectional view of a main part of the indoor unit. The flap 111 attached to the air outlet 121 of the casing 101 rotates about the axis O 2 to flow air blown out of the turbo fan 102. Control.

が大きくなるという問題がある。By the way, in an indoor unit of an air conditioner using the above-described turbo fan, as shown in FIG. In addition, since the air blows outward at an angle of approximately 35 degrees with respect to the tangent line of the outer periphery of the turbo fan 102, the air does not blow out in a direction along a plane substantially perpendicular to the longitudinal direction of the air outlets 121 to 124 of the casing 101. There is a problem that the blowing performance cannot be obtained. As shown in FIG. 8, the air blown out from the outlet 123 on the upper side of the casing 101 immediately flows into the inlet 1 on the front side.
So-called short circuit state sucked into 01a
(Shown by an arrow R2), and there is a disadvantage that the conditioned air does not reach the living space and the comfort is impaired. In addition, the wind easily flows along the wall surface, which may stain the wall surface. Further, if a safety mechanism is provided to prevent injury by putting a fingertip or the like into the outlets 121 to 124, there is a problem that the product size is increased.

By controlling the air flow from 1 to 24,
Since the air is blown out from the air outlets 21 to 24 in a predetermined direction, and the plane blades 4 of the air flow control members 11 to 14 do not blow air forward from near the front edge of the air outlets 21 to 24, the casing 1 There is no so-called short circuit state in which the air is immediately sucked into the suction port 1a on the front of the vehicle. Therefore, the air can be blown out from the air outlets 21 to 24 in a predetermined direction, and a short circuit state can be prevented, so that the comfort can be improved. In addition, the air flow control members 11 to 14 prevent the wind from flowing along the wall surface, thereby preventing the wall surface from being stained. In addition, by narrowing the interval between the curved blades 6 so that a fingertip or the like does not enter, the airflow control members 11 to 11 are reduced.
Since 14 also serves as a safety mechanism, safety can be ensured without increasing the product size.

く、高い安全性が得られる。Therefore, according to the air conditioner indoor unit of the first aspect of the present invention, the turbo fan is disposed on the front side in the rotation direction of the turbo fan and outwardly by, for example, approximately 35 degrees with respect to the tangent line on the outer periphery of the turbo fan. The air blown out from the air flow control member is guided along the planes of the two plane blades and the curved surfaces of the plurality of curved blades, and is blown out in a predetermined direction from the air outlet. Since it does not blow out, it is not immediately sucked into the suction port on the front of the casing. Therefore, it is possible to improve comfort by blowing out the air from the air outlet in a predetermined direction and preventing the air blown out from the air outlet from being immediately sucked from the air inlet into a so-called short circuit state. Further, the air flow control member prevents the wind from flowing along the wall surface, thereby preventing the wall surface from being stained. Further, by narrowing the interval between the plurality of curved blades of the air flow control member so that a fingertip or the like does not enter the air flow control member, the air flow control member also functions as a safety mechanism, so that high safety can be achieved without increasing the product size. Is obtained.

性が得られる。Therefore, according to the indoor unit of the air conditioner according to the third aspect of the present invention, air is sucked in from the front side of the turbo fan through the heat exchanger, and the conditioned air exchanged by the heat exchanger is exchanged. On the front side in the rotation direction of the turbofan, and by blowing out, for example, approximately 35 degrees outward with respect to the tangent to the outer periphery of the turbofan, the blown air is separated from the plane of the two plane blades of the airflow control member by a plurality of planes. It is guided along the curved surface of the curved blade and blows out in a predetermined direction from the outlet, and does not blow air forward from the outlet, so that it is not immediately sucked into the inlet on the front surface of the casing. Therefore, while blowing out from the outlet in a predetermined direction, the air blown out from the outlet is prevented from being in a so-called short circuit state in which the air blown out from the inlet immediately,
Comfort can be improved. Further, the air flow control member prevents the wind from flowing along the wall surface, thereby preventing the wall surface from being stained. Further, by narrowing the interval between the plurality of curved blades of the airflow control member so that a fingertip or the like does not enter the airflow control member, the airflow control member also functions as a safety mechanism. Is obtained.
