FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 shows the appearance of a window type air conditioner, where 1 is an air conditioner body,
2 is a front panel. The front panel 2 is provided with a detachable suction grille 3, a blow-out port 4, and an operation panel 5. The suction grille 3 has a suction port 6 for room air, and the blow-out port 4 supplies blow-off air to the room. A plurality of wind direction plates 7 rotatably supported in order to transmit the air to a wide area, and a plurality of operation knobs 5a, 5b, 5c, etc. are provided on the operation panel 5.

FIG. 2A is a side view showing the positional relationship between the wind direction plate 7 rotatably supported by the outlet 4 and the driving device thereof, and FIG. 2 (c) is a perspective view of the components arranged inside the rear of the operation panel 5 described above, and in each drawing, 8 is a plurality of wind direction plates 7 connected. A connecting plate (also referred to as a louver link) has a plurality of holes 8 provided at equal intervals corresponding to the connecting pins 7a of each wind direction plate 7.
a and a long hole 8b provided partially extending rearward.

The driving device for the wind direction plate 7 according to the present invention has a configuration in which a motor 9 serving as a driving source and a disk-shaped cam 10 provided at the lower rear of the connecting plate 8 are mechanically separated. The feature is that. The motor 9 is fixed at a predetermined position inside the rear of the operation panel 5 with the rotating shaft 9a facing upward.
Is fixed, and a columnar magnet 12 is fixed near the outer periphery of the upper surface of the disk 11.

On the other hand, the upper surface of the disc-shaped cam 10 provided at the lower rear of the connecting plate 10 has a hole 8
b is provided, a support shaft 10b is provided in the center of the bottom surface, and a lower portion of the support shaft 10b is formed in a shaft hole 14 formed in an inner bottom surface (partition wall) 13 of the outlet 4.
The shaft hole 1 is rotatably supported.
4 (support shaft 10) is provided coaxially with the rotation shaft 9a of the motor 9. Further, a magnetic body 15 corresponding to the magnet 12 is fixed at a position apart from the center of the bottom surface of the cam 10 (a position facing the magnet 12). With the driving device described above, the cam 10 can be indirectly driven by the attraction force of the magnet 12 to the magnetic body 15, and the connecting plate 8 can be reciprocated right and left to rotate the wind direction plate 7. .

FIG. 3 shows a structure in which the operation of the above-mentioned driving device is considered to be more stable. 16 is a balancer for preventing the disk 11 from inclining due to the weight of the magnet 12, and 17 is a magnetic material. Is a balancer that prevents the cam 10 from inclining due to the weight. In order to prevent the cam 10 from tilting, a disc-shaped, slippery composite that slidably abuts the center of the support shaft 10b of the cam 10 and the inner bottom surface 13 of the air outlet 4 (around the opening of the shaft hole 14). Collar 10 made of resin
c may be provided. In order to make the rotation of the cam 10 smoother, a gentle spherical surface may be formed on the bottom surface of the magnetic body 15, or the cam 10 may be formed on the inner bottom surface 13 of the outlet 4 centering on the shaft hole 14. A configuration may be adopted in which a thin spacer made of a synthetic resin having a good diameter and a good slip is interposed.

[0011]

According to the driving apparatus described above, the motor disposed inside the rear of the operation panel and the cam disposed inside the rear of the air outlet are not mechanically connected to each other. Swing operation is possible, so that it is not necessary to provide a hole for passing the rotation shaft of the motor in the partition wall between the motor and the cam, thereby eliminating the need for a sealing material for closing the above-mentioned hole and shortening the time required for assembly. Quality is expected to improve.
