Description

TECHNICAL FIELD The present invention relates to an air-cooled air conditioner that exchanges heat with air.

2. Description of the Related Art Conventionally, a compressor-mounted unit of this type of air-cooling type air conditioner has been constructed as shown in FIGS. 3 and 4 as shown in Japanese Utility Model Publication No. 55-20058, for example. .

That is, a dish-shaped substrate 2 is arranged at the bottom of the unit 1, and a vertical cylindrical compressor 3, an L-shaped heat exchanger 4, a propeller fan 5 and an electric motor 6 for driving the same are placed on the substrate 2. The heat exchanger 4 is placed vertically with respect to the substrate 2, and the air-cooling air is supplied with an arrow by the ventilation circuit including the propeller fan 5 whose unidirectional axis is located in the horizontal direction.
As in F1, the structure is such that it flows in from the surface 7a on the heat exchanger 4 side of the unit 1 and the surface 7b facing the compressor 3, and is discharged to the air outlet 8 on the front of the unit.

Further, the compressor 3 is mounted in a portion 3a which is adjacent to the ventilation circuit and forms a separate partition along the longitudinal direction in the unit.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in such a configuration, as shown in FIG.
In order to use 7a, 8 and one side surface 7b adjacent thereto, it is necessary to install the unit at a predetermined distance L1, L2 from the obstacle 9 such as a house. , It was considerably larger than the plane area of the unit.

In addition, since the placement area of the compressor is independently occupied inside the unit, there is a drawback that the size of the unit becomes large.

Therefore, the present invention makes it possible to install the back surface of the unit in close contact with a house or the like by not using the back surface side of the unit as a ventilation surface, and to mount the compressor in an extra space outside the ventilation circuit inside the unit. By placing it, it is possible to form a high-performance ventilation circuit that allows smooth flow of air and to make the unit compact.

Means for Solving the Problems In order to solve the problems, the air-cooling type air conditioner according to the present invention is provided with a vertical air-cooling air outlet on the right side surface of a unit centrally arranged with a compressor, A cross flow fan and a motor having a rotary shaft in the vertical direction are arranged inside the unit so as to face it, while an air cooling air outlet in the vertical direction is provided on the left side surface of the unit. A cross flow fan and an electric motor having a rotary shaft in the vertical direction are arranged, and an air cooling air suction port is provided between the air blowing port on the right side and the air blowing port on the left side, and a flat plate shape is parallel to the suction port. The heat exchanger is mounted on the right side and the left side air outlets, the right side and left side cross flow fans, the heat exchanger, and the air suction port are communicated with each other in a shape to partition the heat exchanger and the compressor. Blower circuit It is what constitutes.

Operation With this configuration, the air for cooling is sucked in from the front side of the unit and blown out from both side surfaces, so that the back side of the unit can be installed in close contact with a house or the like.

Also, by placing the compressor in the surplus space of the unit that is not used for the ventilation circuit, it is possible to construct a high-performance ventilation circuit that utilizes the effective space, and reduce the widthwise dimension of the unit. Is possible.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 shows an outdoor unit 1 of a separated air-cooling type air conditioner.
FIG. 2 is a vertical cross-sectional configuration diagram in which the present invention is applied to FIG. As shown in FIGS. 1 and 2, the compressor 10 is provided at the center of a rectangular plate-shaped substrate 2 having an upward line on the periphery thereof.
Is placed. On the other hand, on the long side 2a of the substrate 2, a plate-shaped heat exchanger 11 is placed perpendicular to the substrate over substantially the entire width of the unit 1. As shown in FIG. 2, a partition wall 12 is provided between the heat exchanger 11 and the compressor 10 with a predetermined gap from the heat exchanger surface, and the partition wall 12 is extended in the left-right direction so that the blower circuit The wind tunnel wall. Air-cooling air outlets 13 and 14 are provided on the left and right sides of the heat exchanger 11, respectively, and at the rear of the left and right edges of the heat exchanger 11, respectively, perpendicular to the side 2a of the substrate 2, and a cross flow fan. 15 and 16 and electric motors 17 and 18 are provided, and the heat exchanger 1
1, the wind tunnel wall 12, the cross flow fans 15, 16 to form a blower circuit of this unit.

With the above configuration, the air for cooling air is drawn in from the front side of the unit by the heat exchanger 11 and the wind tunnel wall as indicated by arrow F2 in FIG.
Separated from the 12 spaces to the left and right, each cross flow fan
The air flows through the air outlets 13 and 14 through 15 and 16, and is blown to the left and right side surfaces of the unit. As a result, since there is no air flow to the rear side of the unit, the rear side can be installed in close contact with a house or the like.

Further, in the present embodiment, the compressor placement section can be arranged behind the blower circuit, and there is no protruding portion of the wind tunnel wall for placing the compressor, so that the flow of wind is not impeded. A high-performance blower circuit can be configured. In addition, since the compressor partition effectively uses the extra space outside the blower circuit, the unit volume can be reduced.

With the above configuration, according to the present embodiment, since the back surface of the unit is not used in the air intake / exhaust direction, the depth dimension when the unit is installed is not limited, and the installation workability can be improved.

EFFECTS OF THE INVENTION According to the present invention, an air-cooling air suction surface is provided on the front side of a unit, a heat exchanger is placed on this surface to form a blower circuit, and the left and right side surfaces of the unit each have an air-cooling air blower. By providing an outlet, it is not necessary to keep the distance between the back of the unit and the house, and the compressor can be mounted in the extra space outside the air blow circuit between the two cross flow fans. With the shortening, the depth dimension can be effectively used, and the unit can be downsized.
