[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for controlling air blowing of an air conditioner, and more particularly, to a blade which is disposed in a longitudinal direction at an air outlet to a room and changes the direction of air blowing in the longitudinal direction. TECHNICAL FIELD The present invention relates to a method and an apparatus for controlling air blowing of an air conditioner for controlling blowing of blowing air.

[0002]

2. Description of the Related Art An air conditioner generally has an elongated outlet a into a room as shown in FIGS. 9 (a) and 9 (b), corresponding to its longitudinal dimension. The cross flow fan b having a length is designed so that air can be blown out at a uniform air volume and air speed over the entire region in the longitudinal direction of the outlet a. In such outlet a,
As shown in FIG. 9 (a), the blade c rotates up and down so as to adjust the blowing direction of the blown air up and down, and rotates right and left so as to adjust the longitudinal direction of the outlet a, that is, the left and right direction. The blades d are provided, and a large number of the blades d are arranged in the longitudinal direction of the outlet a.

Conventionally, by blowing a plurality of blades d1 on both sides in the longitudinal direction of an outlet a to a closed position as shown in FIG. 9B, air is blown out from the outlet a.
There is already known a technique for increasing the wind speed of the blown air to concentrate the blown air in a target range and making it easier to reach by concentrating the blown air at a central portion in the longitudinal direction of the unclosed blade d2.

[0004]

However, in a concentrated blowout state in which the blades d are only partially closed, a large load acts on the cross flow fan b, and the cross flow fan is likely to generate abnormal noise due to pulsation. This is because the blown air blown toward the entire area of the outlet a is closed blade d.
And the abrupt stop is reached, and a rapid throttle state accompanied by a sudden change in the direction toward the center as shown by the solid arrow e in FIG. It is considered that a collision flow as shown by a dashed arrow f occurs or air turbulence occurs. Further, in such a concentrated blowing method, there is also a problem that the wind speed does not increase efficiently and does not easily reach the target range, even though the blowing air is restricted to the center of the blowing port.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method and apparatus for controlling an air outlet at an air outlet of an air conditioner, which can achieve a concentrated outlet of air into a room quietly and sufficiently increase the wind speed. It is in.

[0006]

The indoor air is sucked into the indoor unit A through the air filter 12. The drawn indoor air passes through the heat exchanger 3, is cooled or heated according to the cooling or heating operation mode by heat exchange therewith, and is drawn into the cross flow fan 4. The heat-exchanged air sucked into the cross flow fan 4 passes through a ventilation path 7 formed by a rear guider 5 around a rear portion of the cross flow fan 4 and a stabilizer 6 at a lower front side of the cross flow fan 4, and a front surface thereof. The air is blown into the room from the air outlet 8 provided between the cover 1 and the main body frame 11 to cool or heat the room.

Since the switching of the position of the blade 10c between the concentrated blowing mode position and the normal mode position is instantaneously achieved by a simple movement of turning one base 14 supporting each of the blades 10c, the mode can be achieved. Switching is fast, and the structure is not particularly complicated. In particular, in the first embodiment, as shown in FIG. 3, one of the shafts 10b of the blades 10c supported by one base 14, more preferably, the shaft 10b of the blade 10c on the most central side, Each of the shafts 32 of the table 14 has a double shaft structure that can be individually rotated, and

When the blade 10c has finished moving to the concentrated blowing mode position, the reversible motor 24 is stopped. When the normal mode is set in the operation mode of the concentrated blowing mode, the control means 23 drives the reversible motor 24 to rotate in the reverse direction, and the base 14 of the blade 10c at the position of the concentrated blowing mode is first shown by a virtual line in FIG. After turning to the normal mode position, the blade 10c is returned to the normal mode position by rotating the blade 10c to the open position, and the reversible motor 24 is stopped.

As shown in FIG. 7, the blades 10 c are blown from the normal mode position shown by a virtual line in FIG. The guide surface 10e is formed near the edge 10a1 on the downstream side in the direction and is moved to the concentrated blowing mode position shown by a solid line in FIG. The guide is guided toward the central portion in the longitudinal direction by the guide surface 10d which is located on the downstream side in the blowing direction, and is controlled so as to be concentrated and blown out from the central portion.

According to such control, when the plurality of blades 10c on both sides in the longitudinal direction of the outlet 8 are closed to execute the concentrated blowing mode, the blades 10c on both sides are brought together in the concentrated blowing mode position. A guide surface 10e is formed near the edge 10a1 on the downstream side of the unclosed blade 10a in the blowing direction of the central portion, and the air blown toward both sides in the longitudinal direction of the outlet 8 is directed to the central portion.

Provide.

In such an apparatus, the control means 58 controls the operation of the opening / closing drive means 56 and the slide drive means 57 in accordance with the selected mode, thereby automatically switching between the normal mode and the concentrated blowing mode. Mode switching, since the switching of the positions of the blades between the concentrated blowing mode position and the normal mode position is instantaneously achieved by a simple movement of moving one base 14 supporting each of them. And the structure is not particularly complicated.

Incidentally, the opening / closing drive means 5 in the third embodiment
6 is a reversible motor 55 whose operation is controlled by a control means 58, and a drive gear 54 connected to the reversible motor 55.
And a passive rack portion 53 supported by a guide (not shown) so as to advance and retreat on the axis, and meshing with the drive gear 54.
a at the tail end and one blade 10c on the base 14 at the tip.
In the same manner as in the first embodiment, it is constituted by a fixed passive gear 52 and a rod 53 having a driving rack portion 53b meshing therewith. The slide driving means 57 moves the base 14 to the upstream side in the air blowing direction. Urged by a spring 51,
The rod 53 is commonly used to receive the base 14 at a predetermined position by the step 53c.

In the normal mode, the rod 53 is further retracted from the position where the stepped portion 53c abuts on the base 14 at the normal mode position indicated by the imaginary line shown in FIG. 10c is rotated to the open position. When the concentrated blowing mode is set in the normal mode state, the reversible motor 55 is driven to rotate forward and the rod 53 is rotated.

It is assumed to be the concentrated blowing mode position shown. When this is completed, the reversible motor 55 is stopped.

In this state, when the normal mode is set, the reversible motor 55 is driven to rotate in the reverse direction, and returns to the normal mode state by an operation reverse to the above operation.

The control means 58 is similar to the control means shown in the first embodiment, and a detailed description is omitted.

However, the drive source is not limited to motors, and the shaft 10 is driven by an actuator that moves linearly.
It is preferable to appropriately convert the rotation into rotations of b and 32.
Of course, b and 32 may be driven by separate actuators.

(Embodiment 4) Embodiment 4 is shown in FIG. 8 and, similarly to Embodiment 3, the blades 10c on both sides in the longitudinal direction of the outlet 8 are closed in the concentrated outlet mode, and When the slide 14 is moved to the concentrated blowing position in the drawing, the blade 10a at the center is rotated to the inclined position as shown in FIG. 8, in which the blowing air is guided toward the center in the longitudinal direction of the blowing port 8.
