Description

TECHNICAL FIELD The present invention relates to an outdoor unit of an air conditioner, and more particularly to an outdoor unit that can be installed on each floor of a multi-storey building (hereinafter referred to as a building). .

[Prior Art] FIG. 4 is a vertical cross-sectional view in which an outdoor unit of a conventional air conditioner is installed on a veranda of a multi-storey building such as an office building. In FIG. 4, (1) is the balcony of the building, (2) is the basic concrete provided on a part of the veranda (1), and (3) is the outdoor unit installed on the basic concrete (2). The outdoor unit (3) is a refrigerant circuit component such as a compressor (4),
It is composed of an outdoor heat exchanger (5), a blower (6), and a box (7).

The outdoor heat exchanger (5) is installed diagonally inside the box (7), and the air blower (6) is composed of an electric motor (8) and a propeller fan (9), and the outdoor side inside the box (7). It is mounted above the heat exchanger (5). The box body (7) is provided with a suction port (10) on the front side wall,
An outlet (11) is provided on the upper wall.

Next, the operation of this outdoor unit will be described. During operation of the air conditioner, the compressor (4) is driven and the refrigerant circuit operates, so that the outdoor heat exchanger (5) functions as a condenser or an evaporator to raise or lower the temperature. At the same time, the air blower (6) is also operated so that outdoor air is sucked into the box (7) through the inlet (10) provided on the front side wall of the box (7), and the outdoor heat exchanger (5 ), The air is heated or cooled, and this air is blown out through the air outlet (11) provided on the upper wall of the box (7).
Is discharged above the outdoor unit (3).

[Problems to be Solved by the Invention]

Since the outdoor unit of the conventional air conditioner is configured as described above, when installed on each veranda or balcony of a multi-story building, the air outlet (11) has an outlet (11) on the top wall of the box (7). The air passing through the outdoor heat exchanger (5) is installed in the
As it is blown upward from (11), the blown exhaust flow hits the balcony and balcony on the upper floor, and the suction port (1
There was a problem that it returned to 0) and became a short cycle operation, the protection device of the air conditioner was activated, and the operation became impossible.

There is also an example in which an inverted L-shaped blowing duct is installed in the upper part of the outdoor unit, but in this case, the duct becomes taller so that it can be seen from the outside and poses a design problem, or the duct becomes an obstacle to the building. There was a problem that it was not possible to secure daylight from the windows of the. The present invention has been made in view of the above circumstances, and provides an outdoor unit for an air conditioner that can eliminate the chow cycle operation and can perform stable operation.

[Means for Solving the Problems]

An outdoor unit for an air conditioner according to the present invention includes a box body having a suction port on a front side wall, an outlet on an upper wall, an outdoor heat exchanger arranged in the box body, and the heat exchanger. An air blower that blows the air that has passed through the outlet upward from the outlet, and is located above the outlet, inclining in one direction while holding a predetermined gap, respectively, and its height is sequentially increased in the direction of this inclination. And a blowing guide having a plurality of guide plates configured to be lowered.

[Action]

The outdoor unit in the present invention can change the blowing direction of the exhausted air obliquely by providing the blowing guide in the air blowing portion, can prevent the short cycle operation, and enable stable operation of the air conditioner. , Design and lighting are improved.

〔Example〕

Hereinafter, the configuration and the like of the present invention will be described in detail with reference to embodiments shown in the drawings.

1 is a sectional view showing an outdoor unit of an air conditioner according to the present invention, FIG. 2 is a perspective view of a blowing guide, and FIG. 3 is a perspective view showing an installation example of an outdoor unit according to the present invention. 4, the same members as those in FIG. 4 are designated by the same reference numerals, and detailed description thereof will be omitted.

In FIG. 1, (12) is a balloon guide, which is a box body.
(7) It is attached above the air outlet (11) provided on the upper wall. As shown in FIG. 2, the blowing guide (12) includes a duct-shaped frame (13) having a short cross section and a duct-shaped frame (13).
It is composed of a plurality of guide plates (14) fixed to the side plates (13a) and (13b) constituting the left and right sides of the. Side plate
(13a) and (13b) are diagonally raised from the front surface to the rear surface of the box body (7) in a proportional manner. Along with the shape of the side plate (13), the guide plate (14) is also higher toward the rear, and the mounting state is such that the upper part is tilted forward. The outdoor unit of the air conditioner configured in this way is
As shown in FIG. 3, the guide plate (14) of (12) is installed so as to be inclined from the veranda (1) of the multi-story building (15) such as an office building to the outside opening side of the building.

Next, the operation of the outdoor unit of the air conditioner of the embodiment configured as described above will be described.

When the air conditioner is in operation, the compressor (4) is driven and the refrigerant circuit operates, and the outdoor heat exchanger (5) acts as a condenser during cooling and rises in temperature, while during heating it acts as an evaporator and decreases in temperature. . At the same time, the air blower (6) is also operated so that outdoor air is sucked into the box (7) through the inlet (10) on the front side wall of the box (7), and the outdoor heat exchanger (5) is removed. By passing, the air is heated or cooled and blown out from the blowout port (11) to the blowout guide (12).

Further, the air blown to the blow-out guide (12) changes its blowing direction because the guide plate (14) is inclined obliquely forward, and is blown out obliquely forward to be discharged to the outside of the building.

〔The invention's effect〕

As described above, according to the present invention, the air blown by the air blower of the outdoor unit of the air conditioner is blown obliquely by the guide plate in the blow guide by passing the blow guide provided at the upper portion of the box outlet. The exhaust gas is discharged to the outside of the building, mixed with the outside air, and the temperature rise and fall of the air is eliminated, and there is no fear of causing a short cycle operation. Therefore, the hot air does not hit the balcony on the upper floor.

In addition, the shape of the blowing guide also rises diagonally from the front to the rear, and the guide plate is also inclined diagonally to the front, so the height of the blowing guide can be kept low and the outlet can be seen from the outside. There are no design problems. Since the height of the balloon guide is also low, there is no problem that it is impossible to illuminate from the window of the building.
