Description

[Detailed Description of the Invention] The direction of air blown from an air conditioner or the like is adjusted in the vertical and horizontal directions by rotating a louver provided at the air outlet.

However, there is a limit to the range of wind direction adjustment using only the louvers.

In other words, the direction of the mainstream wind is determined by the fan casing, and the wind near the louver tries to follow the direction of the louver, but as it leaves the louver, the influence of the mainstream determined by the fan casing becomes stronger, and the direction of the blowing wind becomes Regulations are not sufficient.

In view of the above, the present invention attempts to provide a wind direction control device with a wide adjustment range of wind direction.Hereinafter, an embodiment in which the present invention is applied to a ceiling-suspended air conditioner will be explained in detail with reference to Figs. 1 to 5. explain.

In FIG. 1, 1 is a louver, 2 is a curved plate, 3 is a fan casing, 4 is a fan rotor, 5 is a rotating shaft of the louver 1, and 6 is a heat exchanger.

The louver 1 is rotatable by an angle θ around an axis 5 perpendicular to the air flow within the air flow path in the air blowing lower.

The curved plate 2 is attached to a side wall 8 whose limit is the air blowing lower, and has a flat surface A forming an angle α as shown in FIG.
and surface B.

As shown in FIGS. 3 and 5, when the louver 1 is rotated to the maximum wind direction angle θ, the surface B is made to be approximately parallel to the louver 1 with a distance X2 apart, and the surface A is When the louver 1 is set at the minimum wind direction angle O, it is arranged to be substantially parallel to the louver 1 with a distance X1 substantially equal to the distance X2 between the louver 1 and the louver 1.

The angle α formed by the plane A and the plane B is set so that when the air flow flows along the plane B, the planes A and B separate at the adjacent edge C, as shown in Fig. 3. It is prevented from flowing.

The louver 1 has a flat plate shape, and a shaft 5 is located approximately in the center thereof, and this shaft 5 is arranged approximately on the bisector of the angle α formed by the surface A and the surface B of the curved plate 2. .

Furthermore, when the louver 1 is tilted to the minimum wind direction angle O so as to be parallel to the surface A, one end 1a of the louver 1 overlaps the surface A by a distance of X1 by a length of 11, and the louver 1 When the louver 1 is tilted to the maximum wind direction angle θ so as to be parallel to the plane B, the other end 1b of the louver 1 is separated from the plane B by a distance X2 and has an overlapping length of 12.

Thus, as shown in FIG.
In this case, the air flow passes through a parallel flow path bounded by the louver 1 and the surface B of the curved plate 2, and separates at the adjacent edge C, so it flows out parallel to the louver 1, and the wind direction can be changed significantly.

Similarly, when the louver 1 is set to the minimum wind direction angle O as shown in FIG. leak.

In the device of the present invention, the louver 1 tilts around the axis 5 on the bisector of the angle formed by surfaces A and B of the curved plate 2, so even when the louver 1 is set to the maximum wind direction angle θ, the minimum wind direction angle 0 Also, the distance X2 between the louver 1 and the surface B of the curved plate 2 and the surface A
The distance between the louver 1 and the curved plate 2 is approximately equal to the distance The wind direction can be changed without causing an increase in air resistance due to expansion or contraction in the air flow path.

In addition, in the device of the present invention, the louver 1 is placed on the surface A of the curved plate 2.
Or, when tilted parallel to surface B, either end overlaps surfaces A and B by a distance, so surface A
Alternatively, B and the louver 1 can create a parallel air flow path, thereby guiding the wind along the louver 1 and reliably changing the wind direction.

FIG. 6 shows a case where the present invention is applied to a floor-standing air conditioner, and FIG. 7 shows a case where the present invention is applied to a wall-mounted air conditioner.

In FIG. 6, members denoted by the same reference numerals as those in FIG. 1 indicate the same members.

As specifically explained in the embodiments above, the present invention has the following features:
In the air flow path at the air outlet, not only a louver but also a specially shaped curved plate with flat surfaces A and B is attached to the side wall that limits the air outlet. The control range is significantly expanded compared to conventional ones, and the problems of conventional ones can be solved with an extremely simple structure.
