Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor unit of an air conditioner.

[0002]

2. Description of the Related Art An outdoor unit of an air conditioner is installed outdoors. However, in recent years, it has often been necessary to install an outdoor unit on a veranda of a house or in an alley between houses, for example. Case of installing the outdoor unit in such a veranda on Toka alley portion, as shown in FIGS. 9 and 10, the outdoor unit Z ₀
Is installed between two opposing walls 51 and 52 at a relatively small interval and close to one wall 51 side.

The outdoor unit Z ₀ is, for example, a casing 2
By a fan 23 arranged to face the air outlet 22 provided in the front plate 21 of 0 sucks outdoor air A ₁ on board through the heat exchanger 24 and 25 respectively provided on the rear side and the side surface of the casing 20 , The heat exchanger 2
So that the blown to the outside through the outlet grille 30 which warm air or cool air after being heat-exchanged is disposed from the outlet 22 as the outlet air A ₂ subsequently flow side in 4, 25.

[0004] In this case, from the viewpoint of diffusional release into the atmosphere without staying air blown A ₂ blown to the outside through the outlet grille 30 in the periphery of the outdoor unit Z _0, 11
As shown in, the outlet grille of a plurality provided in 30 blades 31 and 31, a ... sectional shape, and a concave curved section on the upper surface side, the outlet air A ₂ respective blades 31,
.., And are deflected obliquely upward and blown out.

[0005]

However, when the blades 31, 31,... Are provided with a deflecting function as described above, as shown in FIGS.
Most of the outlet air A ₂ blown from 0, after being blown out is deflected from該吹out grill 30 diagonally upward,
Although further guided upwardly along the wall 52 collides with the wall 52 which is located in front, a part, as shown by arrow A ₃ in FIG. 10, are deflected to the large lateral , as it is sucked into the machine again, bypassing the side of the outdoor unit Z _0, occurs so-called "short-circuit", the outdoor unit Z due to the occurrence of the short circuit
There was a problem that the heat exchange performance at ₀ was significantly impaired.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an outdoor unit of an air conditioner which can prevent a short circuit of blowing wind as much as possible and can ensure high heat exchange performance. is there.

[0007]

The inventors of the present application BACKGROUND OF THE INVENTION, consider the flow of state air blown A ₂ in order to investigate the cause of such as the above-mentioned "short circuit", As a result, it was found that such as the following.

Namely, as shown in FIG. 12, usually, the outlet grille 30 of the outdoor unit Z ₀ is substantially parallel with a predetermined spacing a plurality of blades 31 and 31, a ... vertically extending substantially horizontally And the blades 31, 31,... Are arranged between the blades 31, 31,.
Have a grid-like planar form that is supported by a plurality of support bars 32, 32 extending in a direction substantially perpendicular to and arranged substantially in parallel. In addition, each of the support bars 32, 3
13 have a constant depth width regardless of the arrangement position in the outlet grill 30 as shown in FIGS.

On the other hand, the rotation direction of the fan 23 is shown in FIG.
And a straight line La passing through the rotation axis P of the fan 23 and orthogonal to the longitudinal direction of the blade 31 and a straight line orthogonal to the straight line La as viewed by the axis R as shown by an arrow R. Lb is assumed. Further, the plane range of the outlet grill 30 is divided into four ranges A to D by the straight line La and the straight line Lb.

[0010] Here, looking at the delivery direction of the outlet air A ₂ blown out from the fan 23 to the outlet grille 30 side,該吹out wind A ₂ are under the influence of centrifugal force due to rotation of the fan 23 the The swirling flow turns in the same direction as the rotation direction of the fan 23, and has a velocity component in the tangential direction of the rotation locus of the fan 23.

Headed to in two ranges of the range B is located in the range A and the lower right is located in the upper left, the direction extending in the delivery direction and the blade 31 of the outlet air A ₂ are identical or approximate. On the other hand, in two ranges, a range C located at the lower left and a range D located at the upper right of the blow grill 30, the blow direction of the blow wind A ₂ and the extending direction of the blade 31 are different. It is orthogonal or close to this.

Therefore, the range C of the blowout grill 30
And the blowing wind A ₂ passing through the range D is
1, but is blown obliquely upward undergoing deflection effect by ... sufficiently, outlet air A ₂ through the range A and range B is above the blades 31 and 31, with little subject that the deflecting action by ... It is blown out with a large velocity component to the side. Moreover, in this case, as shown in FIG. 13 (the ventilation state diagram of the above-mentioned range A portion) and FIG. 14 (the ventilation state diagram of the above-mentioned range B portion), the blown wind A ₂ blown out with a large velocity component to the side. each supporting crosspieces 32, 32 located in the flow path, the depth width of ... is almost no deflection action on該吹out air a ₂ relatively small. These results, blowout air A ₂ through the portion of the range A and the range B of the outlet grille 30, the outlet grille 3 in a plan view
Blown out from 0 to obliquely sideward, and serves as a current generated short circuit as shown by arrow A ₃ in FIG. 10.

From the above considerations, the blowout air A blown out from the blowout grill 30 with a large speed component to the side.
It has been found that by preventing occurrence of short circuit, short circuit can be effectively prevented.
