2. Description of the Related Art An outdoor unit of an air conditioner has a structure as shown in FIG. 1, for example, and the inside of its main body 1 is divided by a partition plate 2 which is erected between the front and rear sides of a heat exchange chamber 3 and a machine room. Four
And an L-shaped heat exchanger 5 and a fan 7 driven by a fan motor 6 are arranged in the heat exchange chamber 3, and a compressor 8 and a compressor 8 are provided in the machine chamber 4. A control device (not shown) for controlling the above is disposed. An annular bell mouth 9 is provided on the outer periphery of the fan 7, and a blowing grill 10 is attached to the front surface of the blowout port. In the outdoor unit configured as described above, when the fan 7 rotates in a predetermined direction, the outside air is sucked into the main body 1 through the suction ports 11 on the rear side and the side of the heat exchanger 5, and the heat exchange is performed by the heat exchanger 5. After being blown, it is directed to the front air outlet along the rotation axis of the fan 7, and is delivered to the outside from the air blow grill 10 provided on the front surface thereof. As shown in FIG. 5, the blowing grille 10 mainly includes the vertical bars 10a (the number of the vertical bars 10a is greater than that of the horizontal bars (not shown)), and the horizontal grilles as shown in FIG. There are those that mainly use the crosspiece 10b (the number of horizontal crosspieces 10b is larger than that of the vertical crosspieces not shown).
Blow-off air is easy to be sent out in the front and vertical directions when the main part is 10a, and is easy to be sent out in the front left and right directions when the main part is the horizontal rail 10b.

[0003]

By the way, in recent years, due to the housing situation, restrictions on the installation location of the outdoor unit have increased, and even in a place where there is not a sufficient gap between the outlet of the outdoor unit and the wall surface of the next house, the above-mentioned problem occurs. It may be necessary to install an appropriate outdoor unit. In such a place, blown air hits the wall of the next house and bounces off to reduce the blowing capacity, or the blown air that bounces back to the main body is sucked in from the suction port 11 on the main body side, and the heat exchange performance drops. There is a fear. Therefore, it is an object of the present invention to provide an outdoor unit of an air conditioner capable of delivering blown air to a farther place even when installed in a narrow space such as a wall in front.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and divides the inside of the main body into a heat exchange chamber and a machine room by a partition plate standing in the front-rear direction, A heat exchanger and a fan for sending the heat-exchanged air to the air outlet in the front of the main body are arranged in the heat exchange chamber, a compressor and the like are arranged in the machine room, and an annular bell mouth is provided on the outer circumference of the fan. In an outdoor unit of an air conditioner in which a blow-out grill having a plurality of crosspieces is provided on the front surface of the air outlet, an area mainly including a horizontal crosspiece and an area mainly including a vertical crosspiece are provided in the blowout grill. For example, in the case where the air outlet is located on the left side in front of the main body and the intake port for outside air is on the back surface and the left side surface of the main body, a vertical bar is provided above the diagonal line connecting the upper right and lower left of the air outlet. The main area is, and the lower part is the horizontal rail. Configured as a region.

[0005]

With the above structure, the advantages of the vertical crosspiece and the advantages of the horizontal crosspiece can be effectively utilized. For example, the air outlet is located on the left side in front of the main body, and the intake port for outside air is With the ones on the back and left sides, the upper part of the diagonal line connecting the upper right and lower left of the air outlet is the area mainly for the vertical bars, and the lower part is the area mainly for the horizontal bars. More of the blown air is sent to the upper front, eliminating the return to the inlet, and in the area below the diagonal, the blown air is sent from the right front to the left front as the fan rotates. The amount of air flowing toward the airflow is reduced, and even if the airflow is installed in a place where there is a shield such as a wall in front, the rebound of the air blown to the air outlet can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows the inside of the outdoor unit from above, and 1 is the main body. The inside of the main body 1 is divided into a heat exchange chamber 3 and a machine chamber 4 by a partition plate 2 provided upright on the base.
And a heat exchanger 5 and a fan 7 driven by a fan motor 6 are arranged in the heat exchange chamber 3,
A compressor 8 and a control device (not shown) that controls the compressor 8, the fan motor 6, and the like are arranged in the.
An annular bell mouth 9 is provided on the outer periphery of the fan 7, and the bell mouth 9 is fixed to the back surface of a blowing grill 10 attached to the front surface of the main body 1. The fan 7 rotates clockwise when viewed from the front, and as the fan 7 rotates, the outside air is sucked into the suction port 11 formed on the back surface and the left side surface of the main body 1.
The air sucked into the heat exchange chamber 3 from the heat exchanger 5 and heat-exchanged by the heat exchanger 5 is sent to the outside from the blowing grille 10 in front of the air outlet.

By the way, the feature of the present embodiment is that the blow-out grill 10 has an area mainly composed of vertical bars and an area mainly composed of horizontal bars so that a wall or the like is provided in front of the outlet. Even so, the amount of air blown back to the air outlet and the suction port 11 is reduced. FIG. 2 shows an example thereof. The area mainly composed of the vertical rails 10a is provided above the diagonal line 12 connecting the upper right and lower left of the outlet, and the area mainly composed of the horizontal rails 10b is located at the upper right of the outlet. It is provided below the diagonal line 12 connecting the lower left corners. With such a configuration, the blown air is directed to the front upper part of the blowout port above the diagonal line 12, and the blown air flowing around the suction port 11 on the left side surface is reduced. On the other hand, below the diagonal line 12, blown air is blown out in the range from the front right to the front left as the fan 7 rotates, but in the area where the cross rail 10b is present, it is blown to the lower front (ground) of the installation surface of the outdoor unit. Since there is little air, even if there is a wall or the like in front of the air outlet, there is almost no bounce back to the air outlet, and the air blow condition is stabilized, so that a predetermined heat exchange is performed.

FIG. 3 shows the heat exchange chamber 3 as described in FIG.
The machine room 4 and the like are all representative of an outdoor unit blow-out grill 10 provided in the left and right positions. This balloon grill
In 10, the upper half of the air outlet is the area mainly composed of the vertical bar 10a,
The lower half is an area mainly composed of the horizontal rail 10b. With such a configuration, the blown air is directed toward the upper front part of the blowout port in the upper part, and the blown air flowing to the suction port on the right side surface is reduced. Further, the blown air is blown out in the range from the front right to the front left as the fan 7 rotates below, but the amount of air blown to the front right is left front depending on the direction of the fan 7 and the cross rail 10b. The amount of air blown to the suction port on the right side surface is small, if any, and the heat exchange performance is not adversely affected. Also, since there is little air blown out to the lower front (ground) of the installation surface of the outdoor unit, even if there is a wall in front of the air outlet, there is no bounce back to the air outlet, and the air blow condition is stable,
A predetermined heat exchange will be performed.

FIG. 4 shows another embodiment.
The inside of the main body 1 has a structure as shown in FIG.
Is a blow-out grill 10 for an outdoor unit in which a machine room 4 is provided on the right side. In this blowing grille 10, the air outlet is divided into upper, lower, left and right regions by a first diagonal line 13 connecting the upper right and lower left and a second diagonal line 14 connecting the upper left and lower right, and the first upper and lower regions. The diagonally upward line 13 is provided in parallel with the diagonal line 13, and the diagonally downward diagonal line 14a is provided in the left and right regions in parallel with the second diagonal line 14. With such a configuration, the blown air vigorously moves forward diagonally upper right in the upper region, diagonally lower right forward in the right region, diagonally lower left forward in the lower region, and diagonally upper left front in the left region. Since it is sent out, even if there is a wall etc. in the front, the blown air does not bounce back to the air outlet and the suction port 11 on the left side, sufficient heat exchange can be expected, and the appearance will be a blowing grille with no discomfort .

[0010]

As described above, the outdoor unit provided with the blow-out grill as described above repels the blown air to the suction port and the blow-out port even when installed in a narrow space such as a wall in front of the blow-out port. And a stable air flow provides a predetermined heat exchange performance.
