In addition, in the machine room 10, there is an electrical parts box (not shown), a compressor 11. A cold tofu circuit (not shown) is installed inside, and the side panel 1b on the right side serves as a service im for maintenance, inspection, etc. of the internal parts.

In the air conditioner having the configuration of 'r, lx, the air (outside air) taken in from the suction port 3.4 is heat exchanged when passing through the heat exchanger 2, and this heat exchanged air is sent to the blower 5. The air is exhausted from the air outlet 6 into the atmosphere.

Note that the arrows in FIG. 1 indicate the air flow direction as described above.

1- In the air conditioner described above, air conditioning in the outdoor unit causes the medium flowing in the heat exchanger 2 to exchange heat with the outside air, thereby performing air conditioning for cooling and heating. .

[To the problem that the invention seeks to solve]

By the way, according to the outdoor units in conventional air conditioners having the above-mentioned configuration, when multiple outdoor units are installed close to each other, as shown in FIG. Since air would be sucked in, there was a risk that the performance of the air conditioner would be reduced. Also, since there must be no obstructions around the four sides of the outdoor unit body, such as the suction port 3.4° service side (1b) and the air outlet 6, multiple outdoor units should be spaced a certain distance from each other. This requires a large space for installation, which is disadvantageous.

The present invention has been made in view of the above-mentioned circumstances, and allows a plurality of outdoor units to be installed side by side with their backs and sides as close as possible to each other, and provides maintenance services such as maintenance and inspection of one machine room, etc. It is an object of the present invention to provide an air conditioner having an outdoor unit that saves installation space and can be easily and appropriately installed.

Measures to Solve Problem C It) The air conditioner according to the invention includes a WL device provided in the opening at the front of the outdoor unit main body, and a heat exchanger whose upper end is inclined forward on the rear side. In addition, between the rear side of the heat exchanger and the back panel, an air outlet that opens above the outdoor unit body is provided as an X path that widens toward the end. It has a structure in which the machine room provided on the side is separated by a partition plate.

[Effect]

According to the present invention, outside air is sucked into the unit by the blower through the opening in the front part of the outdoor unit main body, heat exchange is performed between this outside air and the refrigerant in the heat exchanger, and the air is transferred to the outdoor unit main body. It smoothly hits the back surface of the main body, changes its direction upward, and is exhausted into the atmosphere from the air outlet in the main body.

〔Example〕

Hereinafter, the invention will be described in detail using embodiments shown in the drawings.

FIG. 1 shows an embodiment of the air conditioner according to the present invention, and in the figure, the same or corresponding parts as in FIG. . - Now, according to the present invention, the air suction port 20 is connected to the front panel 2.
In the side suction type outdoor unit main body 1 provided in 1, the suction port 2
A blower Fl 15 consisting of a fan 5b and its drive motor 5a installed facing the air blower 5; and a heat exchanger disposed inside the outdoor unit main body l with the upper end inclined forward on the rear side of the blower 5. 2, and an air opening above the outdoor unit main body l that exhausts the air flow through an exhaust side air passage 23 formed on the 11r side panel 2z side of the outdoor unit main body l behind this heat exchanger 2. By partitioning the lower part of the heat exchanger 2 from the air outlet 24 and the front panel 21 side of the outdoor unit main body l, a suction side air passage 25 from the suction opening 21 is formed, and the r side thereof is connected to the compressor 11. The main feature is that it is configured to include a partition plate 26 that forms a machine room 10 that accommodates electrical components, a refrigerant circuit (both not shown), and the like.

That is, according to the present invention, the outdoor unit of the air conditioner is
A blower 5 is provided on the front panel 21 of the outdoor unit main body 1, with the opening thereof serving as a suction port 20, and a heat exchanger 2 whose upper end is inclined forward is provided on the rear side, and this heat exchanger 2 An air outlet 24 that opens above the outdoor unit main body 1 is provided as an air passage 23 that spreads out between the rear side and the back panel 22, and an air passage 25 in front of the heat exchanger 2 is provided.
It has a structure in which a partition plate 26 partitions the machine room 10 and the machine room lO provided below.

According to such a configuration, the outdoor unit main body l has a vertically elongated configuration with the heat exchange chamber having the heat exchanger 2 and the like located above it and the machine room 10 disposed below.

In addition to reducing the overall size and compactness, the suction port 2
0 to the front of the outdoor unit main body l, and the air outlet 24 to the outdoor unit main body 1.
By forming the outdoor units above, for example, when a plurality of outdoor units are installed in parallel, it is possible to avoid interference between the suction and outlet ports of each outdoor unit, and to arrange the outdoor units in close contact with each other.

In other words, since the air blower n0.5 is attached to the suction "]20, even if the area is relatively small, the suction air t(
This can make the outdoor unit main body l
In this case, the back surface and both side surfaces can have a structure without openings.

Further, according to the present invention, the outdoor unit main body l having the above-described structure is configured such that maintenance and inspection of the machine room 10 can be performed by 1) removing the lower panel portion 21a of the panel 21; This solves the problem of installing multiple outdoor units in parallel. This takes advantage of the fact that in the above-mentioned outdoor unit, a space is always required in front of the suction port, and is easily understood.

Therefore, when multiple outdoor units with such a configuration are installed in parallel, they can be installed side by side on the left and right, and even back to back, as shown in Figure 2. This reduces the installation space and reduces the space required. This effect can be demonstrated when a large number of outdoor units are installed in a small space.

In this embodiment, the side edge of the air inlet 20 formed on the front panel 21 of the outdoor unit main body l is integrally provided as a bell mouth, and the fan 5b protrudes to the outside from the inlet 20 formed by this. The blower 5 is mounted on a retaining plate 27 attached to a side panel or the like of the outdoor unit main body l (not shown) in such a manner that
The installation is fixed. In addition, 28 in Figure 1 covers the propeller fan 5bl of the blower 5 mentioned above.
This is a guard member having a surface layer panel 21. moreover,
The heat exchanger 2 described above has its upper end in contact with the upper inner side of the front panel 21 of the outdoor unit main body 1, and its lower end in contact with the upper inner side of the front panel 21 of the outdoor unit main body 1.
The outdoor unit main body 1 is arranged in an inclined manner so as to be in contact with the lower side of the outdoor unit 2. Further, the partition plate 26 is arranged in a substantially horizontal state so as to be located below the suction port 20 in the outdoor unit main body 1, and its other end extends to the lower end of the heat exchanger 2.

According to the outdoor unit configured as described above, outside air is sucked into the main body 1 by the blower 5 from the front surface (intake port 20) of the outdoor unit main body 1, and between this outside air and the refrigerant in the heat exchanger 2. Heat exchange takes place, and the air smoothly hits the back surface of the outdoor unit main body 1 and is directed upward to the main body 1.
The air is exhausted into the atmosphere from the upper air outlet 24.

Note that this proposal is not limited to the example structure described above,
The shape, structure, etc. of each part may be modified or changed as appropriate. For example, as shown in Figure 3, heat exchange the back panel 22 of the outdoor unit main body 1! The left and right side panels are formed in a trapezoidal shape, and on the back side of the heat exchanger 2, which is arranged at an angle inside the outdoor unit main body l,
An air outlet 24 is arranged parallel to this.

Even in this configuration, when multiple outdoor units are installed in parallel, there will be no interference between the suction and air outlet of the adjacent outdoor units, and even if one E7 is used for personal use, heat exchange will not occur. Since the exhaust air is directly discharged from the device 2 into the atmosphere, there are advantages that the pressure loss is small, the air volume is large, and the performance of the device is improved. In addition, if a U-shaped 4J-shaped rear panel is provided as a separate part, an outdoor unit with approximately the same configuration as described above can be obtained. It becomes possible to obtain an outdoor unit that is inexpensive and lightweight.

[Effect of Issue 1!11] As explained below, according to the air conditioner according to the present invention, the front surface of the outdoor unit main body is used as a service surface for suction and maintenance, and the upper surface is used as a blowout surface. When installing outdoor units in parallel, they can be installed as close together as possible, making it easy to secure the installation space.

This is particularly effective when installed in places where installation space is limited, such as on the roof of a building.In addition, according to the present invention, the area required for each outdoor unit to be damaged can be significantly reduced. Therefore, it has the advantage of being able to solve the problem of installation space when adopting building air conditioning systems, which have recently been changing from large-scale centralized heating and cooling systems to individual heating and cooling systems from the perspective of energy conservation.
