[0007]

The outdoor unit of the conventional separation type air conditioner is constructed as described above, and the lattices of vertical and horizontal rails are provided over substantially the entire surface, and a substantially circular ventilation is provided in the center. In the case of using a grill member designed in a substantially square shape with parts formed, the appearance is designed to be a substantially square shape, and even if the vertical bars and the horizontal bars are arranged in a grid pattern over the entire surface, the appearance is There was a problem that only the round shadow of the ventilation part was noticeable and the appearance was very poor. Therefore, if all the grill members are formed in a lattice shape that allows ventilation, then a problem arises that the round openings of the outer casing are conspicuous and the appearance is deteriorated. In order to solve such a problem, if the seat pushing portion of the outer case is painted black, the round opening becomes inconspicuous, but since the seat pushing portion is integrally formed as a part of the cabinet, other portions are not formed. It is necessary to mask and paint. Therefore, processing workability and mass productivity are poor, and the processing cost is high. Another embodiment (FIG. 2)
As 7), there is a case in which the outer case located at the back of the grid-like grill member is a separate component. In this structure, the partition plate, which is a separate component, is painted black so that a round opening is conspicuous. However, the partition plate 26 is arranged inside the outer casing, and a space corresponding to that is required for the partition plate 26 to be attached to the inside so that the outer casing becomes large. However, there is a problem in that the assembly procedure is complicated and the cost is increased due to the addition of restrictions such as the need to mount the built-in parts after the partition plate 26 is mounted.

The present invention has been made in order to solve the above problems, and is inexpensive, has good workability and mass productivity, and has a good appearance in terms of appearance without increasing the size of the outer case. The purpose is to obtain an outdoor unit with excellent design.

And a right-side front plate 23 having an L-shape, which is located on the right side of and is a part of the right front surface and the right side surface. Inside the right side front plate 23, although not shown, a machine room, an electrical equipment storage portion, etc. are hidden. The side side plates are L-shaped, which is located next to the left side front plate 22 and are a part of the left side face and the left rear face, and the left side rear plate 29 provided with the heat exchange intake air port 30 and the right side plate. The right side rear plate 24 is located next to the front side plate 23 and has an L-shape that is a part of the right side face and the right rear face and also serves as an inspection port at the time of service.
The rear side plate is a lattice-shaped back lattice 3 that also serves as a heat exchange inlet.
It is 1. Further, the side portions of the respective side plates have joint portions (described later) for joining the members adjacent to each other.

The grill member 12 is provided with a blower guide plate 25.
Is the same as the plane outer shape of the blower guide plate 25 and has a substantially quadrangular outer shape, and the whole is a lattice-shaped one composed of vertical and horizontal bars. A hole through which heat exchange exhaust air passes is provided between the vertical and horizontal crosspieces, and fixing portions (described later) for fixing the top plate 3 and the bottom plate 21 are provided at upper and lower ends, respectively.

The procedure for assembling the outer case is as follows. First, the bottom plate 21 is fixed with built-in parts such as a heat exchanger, and the rear grid 3
1 and the left side rear plate 29 and the blower guide plate 25 are screwed to the bottom plate 21, and then the blower guide plate 25 is used as a reference, and one side surface of the right side front plate 23 is provided at both ends of the blower guide plate 25. The left side front plate 22 is fixed together with one side face (described later), the other ends of the left side front plate 22 and the left and right side rear plates 24 and 29 are overlapped and screwed together, and the lower face is screwed to the bottom plate 21. .
