FIGS. 27 and 28 are an external perspective view of an outdoor unit of a conventional separation type air conditioner disclosed in Japanese Utility Model Laid-Open No. 5-10918 and a cross-sectional view of a main part showing a state where a grill member is attached. In FIG. 27, the outer case of the outdoor unit 1 includes a top plate 3, a bottom plate 21, and side plates divided into several parts. The side plates include a left side front plate 22, a right side front plate 23, a right side rear plate 24, a partition plate (blowing guide plate) 25, a rear side plate (not shown), and a left side rear plate. . A blower 26 is mounted on the bottom plate 21 by a compressor, a heat exchanger, and a mounting table. A left front plate 22, a right front plate 23, a right rear plate 24, and a partition plate (blowing guide) are provided around the bottom plate 21. 25), and the upper surface is covered with the top plate 3 to form an outer case. A blower 26 is provided in front of a partition plate (blower guide plate) 25.
A ventilation port 28 having a guide inside is formed in accordance with the diameter of the fan 27, and the front surface thereof is covered with the grill member 12.

[0007]

The outdoor unit of the conventional separation-type air conditioner is constructed as described above, and a grid of vertical and horizontal beams is provided over substantially the entire surface, and a substantially circular ventilation is provided at the center. In the case of using a grill member designed in a substantially square shape with a part formed, the appearance is designed to be approximately square shape, and even if the vertical and horizontal beams are arranged in a grid over the entire surface, There was a problem that only the round shadow of the ventilation section was noticeable and the appearance was very poor. For this reason, if the grill members are all formed in a lattice shape that allows ventilation, the round opening of the outer case will be conspicuous and the appearance will deteriorate. In order to solve such a problem, if the pusher portion of the outer case is painted black, the round opening becomes inconspicuous. However, since the pusher portion is integrally formed as a part of the cabinet, other portions are masked. Need to be painted. For this reason, processing workability and mass productivity are poor, and processing costs increase. 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 another component, is painted black so that the round opening is not noticeable. Although the one that does not impair the appearance can be obtained, the partition plate 25 is arranged inside the outer case, and a space corresponding to the partition plate 25 is required inside the outer case, so that the outer case becomes large, and the assembling procedure is divided. Regulations such as the need to attach built-in components after attaching the plate 25 have been added, and there has been a problem that the assembly procedure is complicated and costs increase.

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

A hole fixed to the top plate 3 and the bottom plate 21 with screws is provided as appropriate. The front side plate is provided at a substantially central portion with a ventilation guide plate 25 provided with a ventilation opening 28 having a cylindrical and aerodynamically appropriate curved surface shape (for example, bell mouth shape), and a left side of the ventilation guide plate 25. L which is part of the left front and left side
It is composed of a left front side plate 22 shaped like a letter and an L-shaped right front side plate 23 located on the right side of the blower guide plate 25 and forming part of the right front face and the right side face. Right side front plate 23
Although not shown, a machine room, an electric component storage unit, and the like are covered and hidden. The left side plate 29 is provided with a heat exchange intake air port 30 and has an L-shape, which is located adjacent to the left front side plate 22 and is a part of the left side and the left rear surface.
It has an L-shape, which is located next to the right front side plate 23 and is a part of the right side and the right rear side. The right side plate 24 also serves as an inspection port at the time of service. The rear side plate is a lattice-shaped back lattice 31 also serving as a heat exchange suction port. Also,
Each side plate has a joining portion (described later) for joining with a member adjacent to each other.

The grill member 12 is provided with a ventilation guide plate 25.
It is arranged on the front surface of, and is substantially the same size as the plane outer shape of the air blow guide plate 25, has a substantially square outer shape, and is a lattice-like structure entirely constituted by vertical and horizontal beams, Holes through which heat exchange exhaust air passes are formed between the vertical and horizontal rails, and upper and lower ends are provided with fixing portions (described later) for fixing to the top plate 3 and the bottom plate 21, respectively.

The procedure for assembling the outer case is as follows. First, a built-in component such as a heat exchanger is fixed to the bottom plate 21 and the back grid 3
1 and the left side plate 29 and the blow guide plate 25 are connected to the bottom plate 2.
1, and then with reference to the air guide plate 25,
One side surface of the right front side plate 23 and one side surface of the left front side plate 22 are fixed to both ends of the blower guide plate 25 (described later).
The other end is overlapped with the joint of the left and right side plates 24 and 29 and screwed together, and the lower surface is screwed to the bottom plate 21. Thereafter, the lower portion of the grill member 12 is fixed to the bottom plate 21 with screws, and finally the lid-shaped top plate 3 is covered from above, and the top plate 3 and each member are fixed with screws.

Next, the operation will be described. As shown in FIG. 2, the outdoor unit 1 includes a grill member 1 for preventing foreign matter from entering.
