DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air outlet structure of an air conditioner which is installed at a high place such as a ceiling and blows conditioned air substantially downward.

[0002]

2. Description of the Related Art A conventionally known ceiling cassette type air conditioner is constructed by disposing a fan 2 and a substantially annular heat exchanger 3 in a box-shaped main casing 1 as shown in FIGS. On the lower surface of the main body casing 1, a rectangular suction port 4 is provided at a central portion, and four rectangular air outlets 5, 5, ... are provided at positions surrounding the suction port 4. . Reference numeral 6 denotes a suction grill, 7 denotes a fan motor, 8 denotes a drain pan, 9 denotes a device such as an electric heater, and F denotes a horizontal blade.

[0003] In this air conditioner, the room air Wr sucked from the suction port 4 is converted into conditioned air Wc heated or cooled in the process of passing through the heat exchanger 3, and from the outlets 5, 5. It is to be blown out into the room (see FIG. 10).

By the way, in the case of the air conditioner having the above configuration,
It is necessary to change the blowing direction of the conditioned air Wc blown from the outlets 5, 5,... During the cooling operation or the heating operation, and this has been dealt with by changing the direction of the horizontal blade F.

[0005]

However, when the conditioned air blowing direction is changed depending on the direction of the horizontal blades as in the above-mentioned conventional example, the horizontal blades are located at the center of the conditioned air blowing flow path. Therefore, there is a problem in that the conditioned air collides with the horizontal blades to generate a large pressure loss and a vortex.

In recent years, air conditioners having annular or arc-shaped air outlets have been developed. In the case of annular or arc-shaped air outlets, the air flow direction of conditioned air is controlled by horizontal blades. In order to change it, there is a problem that a finely divided horizontal blade is required and the structure becomes complicated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and is capable of changing the blowing direction of conditioned air without using horizontal blades by devising a wall constituting an air outlet. It is intended for.

[0008]

According to the first aspect of the present invention, as a means for solving the above-mentioned problem, an air outlet 5 constituted by opposed wall surfaces 10 and 11 for guiding the conditioned air Wc obliquely downward. In the air conditioner having a lower surface, a movable member 12 that changes the blowing direction of the conditioned air Wc from a substantially horizontal direction to a substantially downward direction on one of the wall surfaces 10 and 11 in accordance with the moving position. Is provided.

With the above-described configuration, if the movable member 12 is moved, the blowing direction of the conditioned air Wc changes from a substantially horizontal direction to a substantially downward direction. In this case, the blowing direction of the conditioned air Wc is changed by changing the position of the movable member 12 irrespective of the horizontal blades. As a result, an increase in pressure loss and generation of eddy current can be prevented.

[0010] When the movable member 12 is provided on the wall surface 11 on the back side in the blowing direction of the conditioned air Wc and is moved in the vertical direction as in the second aspect of the present invention, Is simplified.

According to a third aspect of the present invention, there is provided, as a means for solving the above-mentioned problem, an air having a blow-out port 5 formed on the lower surface formed by opposed wall surfaces 10 and 11 for guiding the conditioned air Wc obliquely downward. In the conditioner, the wall surface 11 on the rear side in the blowing direction of the conditioned air Wc is made of an elastic material, and the blowing direction of the conditioned air Wc changes from a substantially horizontal direction to a substantially downward direction in accordance with the deformation state. An elastic deformation member 20 is provided.

With the above configuration, if the elastically deformable member 20 is deformed, the blowing direction of the conditioned air Wc changes from a substantially horizontal direction to a substantially downward direction. In this case, the blowing direction of the conditioned air Wc is changed by the deformation of the elastic deformation member 20 irrespective of the horizontal blade, so that the conditioned air Wc flows along the elastic deformation member 20 regardless of the blowing direction. As a result, an increase in pressure loss and generation of eddy current can be prevented.

As in the fourth aspect of the present invention, a ridge 26 for deflecting the blowing direction of the conditioned air Wc toward the elastically deformable member 20 is provided on the upper surface of the wall surface 10 on the front side in the blowing direction of the conditioned air Wc. Is provided, the conditioned air Wc
Is deflected by the ridge 26 and flows toward the elastically deformable member 20, so that the elastically deformable member 20 can easily change the blowing direction of the conditioned air Wc.

When the outlet 5 is formed in an annular shape or an arc shape as in the fifth aspect of the present invention, the conditioned air Wc is blown out from the annular or arc-shaped outlet 5 which has been conventionally difficult to construct. The direction change can be easily obtained by the movable member 12 or the elastic deformation member 20.

It flows in a substantially horizontal direction through the lower end of the front side wall surface 10 at the outlet 5.

As shown in FIG. 5B, when the movable member 12 is positioned between the upper limit and the lower limit, the lower end of the movable member 12 is located slightly below the lower end of the front side wall surface 10 at the outlet 5. Therefore, the conditioned air Wc is gathered by the curved surface 12a of the movable member 12, but flows obliquely downward because the downward component of the conditioned air Wc is not completely converted into a horizontal component.

As shown in FIG. 5C, when the movable member 12 is positioned at the lower limit, the lower end of the movable member 12 is
Is located below the lower end of the front side wall surface 10 of the movable member 12, the conditioned air Wc is somewhat interfered by the curved surface 12a of the movable member 12, but the conditioned air Wc

The upper end of the elastic deformation member 20 is supported via a spring 22 on the upper end of the rear side wall surface 11. The elastically deformable member 20 is provided with a driving means 23 for changing the curvature of the elastically deformable member 20. The curved surface of the elastic deformation member 20 at the time of maximum deformation has a shape capable of converting a downward component of the conditioned air Wc into a horizontal component.

The driving means 23 comprises, for example, a wire 24 having one end connected to the back side of the elasticity changing means 20 and a winding means 25 for winding the other end of the wire 24. The curvature of the elastic deformation member 20 can be changed according to the degree of taking.

In the case where the conditioned air Wc is almost in contact with the elastically deformable member 20, the main flow of the conditioned air Wc flows toward the elastically deformable member 20 by the ridges 26 provided on the front side wall surface 10 of the outlet 5. After the downward component of the conditioned air Wc is converted into a horizontal component, the conditioned air Wc flows in a substantially horizontal direction through the lower end of the front side wall surface 10 at the outlet 5 due to the Coanda effect.

As shown in FIG. 7B, the amount of winding of the wire 24 around the winding means 25 is reduced, and
When the amount of deformation of the air outlet 5 is reduced,

c has a vector in the same direction as the elastic deformation member 20, and flows substantially downward.

As described above, in the present embodiment, the blowing direction of the conditioned air Wc can be changed from a substantially horizontal direction to a substantially downward direction by deforming the elastic deformation member 20. In this case, the blowing direction of the conditioned air Wc is changed by the deformation of the elastic deformation member 20 irrespective of the horizontal blade, so that the conditioned air Wc flows along the elastic deformation member 20 regardless of the blowing direction. As a result, an increase in pressure loss and generation of eddy current can be prevented.

In this embodiment, in order to easily deflect the main flow of the conditioned air Wc toward the elastically deformable member 20, the ridge 26 is provided on the front side wall surface 10 of the outlet 5. Even without providing the projection 26, the blowing direction of the conditioned air Wc can be changed.

By providing the movable member 12 that changes the horizontal direction, the movable member 12 is moved regardless of the horizontal blade, so that the blowing direction of the conditioned air Wc can be changed from a substantially horizontal direction to a substantially downward direction. Therefore, irrespective of the blowing direction, the conditioned air Wc flows along the movable member 12, which has the effect of preventing an increase in pressure loss and generation of a vortex.

As described in the second aspect of the present invention, when the movable member 12 is provided on the wall surface 11 on the rear side in the blowing direction of the conditioned air Wc and is moved in the vertical direction, Is simplified.

Regardless of the horizontal blade, by deforming the elastic deformation member 20, the blowing direction of the conditioned air Wc can be changed from a substantially horizontal direction to a substantially downward direction. However, the conditioned air Wc flows along the elastically deformable member 20, which has the effect of preventing an increase in pressure loss and generation of a vortex.

As in the fourth aspect of the present invention, the ridge 26 deflects the blowing direction of the conditioned air Wc toward the elastically deformable member 20 on the upper part of the wall surface 10 on the front side in the blowing direction of the conditioned air Wc. Is provided, the conditioned air Wc
Is deflected by the ridge 26 and flows toward the elastically deformable member 20, so that the elastically deformable member 20 can easily change the blowing direction of the conditioned air Wc.
