DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Hereinafter, an example of an embodiment of a ceiling-mounted air conditioner of the present invention will be described with reference to FIGS. FIG. 1 is a cross-sectional view of a main part of a blowout of a four-way ceiling cassette type indoor unit, and FIG. 2 is a perspective view showing a flap provided on a vane. In the figure, 1 is an indoor unit main body, 2 is a front panel of the indoor unit main body 1, 3 is a blowing air path provided in the indoor unit main body 1, and 4 is provided in the blowing air path 3 and blows airflow to a blowout port. A vane 5, which is directed in a predetermined vertical direction, is a shaft of the vane 4 connected to a driving device (not shown) for controlling the vane 4 in a predetermined vertical direction with respect to an outlet, and 6 is a vane 4
A plurality of flaps 7 are provided in the axial direction to direct airflow in the axial direction of the vane 4, and 7 is an outlet.

Is perpendicular to the vane 4 at the center of the vane 4,
The outer side of the vane 4 has a curved shape outward from the vane 4.

In the above, when the indoor unit main body 1 is operated, cool air or warm air blown through the blow air path 3 by a blower (not shown) is passed through a vane shaft 5 by a driving device (not shown). By the controlled vane 4, it expands in a predetermined vertical direction with respect to the blowout port 7 and, by the curved flap 6 provided on the vane 4, in the axial direction of the vane 4 shown by the air flow 8 in FIG. 2. At the outlet 7. The vane 4 can be controlled to rotate in a predetermined vertical rotation range with respect to the outlet 7, and can be fixed at an arbitrary position in the vertical direction.

FIG. 3 shows a case where the four-way ceiling cassette type indoor unit according to the above embodiment is installed in a room, and each vane 4 is fixed at a predetermined position perpendicular to the outlet 7 between the outlets. FIG. 7 is a diagram showing temperature distribution of a room floor surface during heating when actually operated by using isotherms. Since the temperature distribution is targeted at each outlet, the room is divided into quarters around the four-way ceiling cassette type indoor unit.

The airflow blown out from the outlets 7 through the outlet air passages 3 between the outlets is directed by the respective vanes 4 in a predetermined vertical direction with respect to the outlets 7.
And since each flap 6 spreads in the axial direction of the vane 4, the air flow reaches between the outlets which have not reached so far, and the temperature distribution of the floor where the air is blown out (the isothermal line of 19 ° C.). Part) is better than before. That is, in the prior art, there is no flap for expanding the air flow in the axial direction of the vane, and in the present embodiment, the vane 4 has a shape perpendicular to the vane 4 at the center of the vane 4.
Since the flap 6 having a shape curved outward of the vane 4 is provided from the center to the outside, the air current spreads in the axial direction of the vane 4 and the temperature distribution on the floor surface is improved as compared with the conventional case as shown in FIG. .

As described above, the vane 4 for directing the airflow in a predetermined vertical direction with respect to the blowout port 7 and the flap 6 provided on the vane 4 and controlling the airflow in the axial direction of the vane 4 make it possible for the conventional airflow to reach. The air conditioner can reach even the area where it has not been provided, and an easy-to-use ceiling-mounted air conditioner with no unevenness in the temperature distribution in the room can be obtained.

Although the above embodiment has been described as an example in four directions, the present invention can be applied to two directions.

Embodiment 2 FIG. 4 and 5 show the second embodiment.

The shaft of the vane 4 connected to the motor 9 and 6 are a plurality of flaps provided in the axial direction of the vane 4 in order to control the The flap 6 is divided into two parts with the center of the vane 4 as a boundary.
It is rotatably supported at 1 and 12. The lever 1
1 and 12 are connected to motors 15 and 16 via link mechanisms 13 and 14, respectively. Reference numeral 10 denotes a rotating shaft of the flap 6, which penetrates the vane 4 and has one end rotatably supported by the vane 4 and the other end fitted and fixed to the flap 6. The other end of the rotating shaft 10 may be fixed to the flap 6 by bonding or the like.

In the above, the vane 4 is controlled by the motor 9 in a predetermined vertical direction with respect to the outlet 7 through the vane shaft 5, and the two divided flaps 6 are respectively controlled by the motors 15 and 16. Link mechanism 13,
14, the air flow is rotated in the axial direction of the vane 4 by the levers 11 and 12 in the axial direction of the vane 4 by the vane 4 and in the axial direction of the vane 4 by the flap 6. The control is performed in an arbitrary direction. The vane 4 can be controlled to rotate in a predetermined vertical rotation range with respect to the outlet 7.
It can be fixed at any position in the vertical direction.

FIGS. 6 and 7 show an example in which the flap is rotated in the above embodiment. FIG. 6 shows an example in which the two divided flaps are rotated outward in the axial direction of the vane, and FIG. 7 shows an example in which the two divided flaps are rotated in the same direction. Show. In FIG. 6, the first embodiment is rotated by rotating the two divided flaps 6 outward in the axial direction of the vane.
Similarly, the airflow can be controlled so as to spread in the axial direction of the vane 4. In FIG. 7, the air flow can be intensively controlled in an arbitrary direction by rotating the two divided flaps 6 in the same direction. FIGS. 6 and 7 show examples of the rotation of the flap 6, respectively, and the invention is not limited to this. The flap 6 can be controlled to rotate in the axial rotation range of the vane 4. ,
Further, it can be fixed in any direction and position.

FIG. 8 shows a case where the four-way ceiling cassette type indoor unit according to the above embodiment is installed in a room, and each vane 4 is fixed at a predetermined position perpendicular to the outlet 7 between the outlets. When each of the flaps 6 is rotated and fixed so as to face each other in the corner direction between the outlets (the two divided flaps 6 rotate in the same direction as shown in FIG. 7), and the actual heating operation is performed. FIG. 5 is a diagram showing the temperature distribution on the floor of the room by isotherms. In the figure, the room is divided into quarters around a four-way ceiling cassette type indoor unit.

The airflow blown from each outlet 7 between the outlets is changed by each vane 4 into the outlet 7.
The air flow can be intensively blown out between the outlets by the respective flaps 6 which are rotated and fixed in a predetermined vertical direction and in the corner direction between the outlets. Thereby, the temperature distribution of the floor surface in the corner area (the part at the isothermal line of 19 ° C.) is further improved than in the first embodiment. That is, in the first embodiment, the flap 6 provided on the vane 4, that is, the center of the vane 4 has a shape perpendicular to the vane 4,
On the outer side from the center of the vane 4, the air current is blown out by the flap 6 having a curved shape toward the outside of the vane 4 so as to expand in the axial direction of the vane 4, whereas in the present embodiment, the vane 4 is By rotating and fixing the two divided flaps 6 in the same direction, the airflow can be concentrated and blown out in the corner direction, so that the temperature distribution on the floor surface in the corner region is different from that in the first embodiment. It gets even better.

As described above, since a plurality of flaps provided in the axial direction of the vane can be rotated, the airflow can be controlled in an arbitrary direction in the axial direction of the vane, and it is possible to warm or cool the vane. Since the airflow can be directed intensively, a more convenient ceiling-mounted air conditioner can be obtained.

In the above embodiment, a plurality of flaps provided in the axial direction of the vane are separated from the center of the vane by two.
The flaps are divided so as to be rotatably supported by levers at one end side in the depth direction of the flaps, and are rotated by the respective levers. In this case, the motor may be rotatably supported by one) and may be rotated.

In the above embodiment, the vane and the flap may move in conjunction with each other.

Also, in the above-described embodiment, as in the first embodiment, the present invention can be applied to a two-way device.
