Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an outdoor casing in a separation type air conditioner.

[0002]

2. Description of the Related Art Conventionally, there has been an outdoor unit for an air conditioner disclosed in Japanese Utility Model Publication No. 63-42270. This will be described with reference to FIGS. Reference numeral 1 denotes a bottom plate, on which a compressor 8, a heat exchanger 9, a blower 10, a partition plate 11 and an electric component box 12 are placed. Reference numeral 14 is a substantially vertical back plate having a suction port 15. The back plate 14 and the bottom plate 1 are integrally formed in an L shape to form a base plate portion 16. Further, 5 is a top plate, and 7 is a front plate provided with an outlet 17. A cabinet portion 18 is formed by integrally forming the front plate 7 and the top plate 5 into an inverted L shape. And the base plate portion 16
And the cabinet portion 18 are engaged with each other to form a cylindrical body whose both side surfaces are open, and the both side surface opening portions are closed by lid-shaped side plates 19 and 20, respectively, to form a housing.

Next, the operation will be described. A compressor 8, a heat exchanger 9, of the bottom plate 1 of the base plate portion 16 which is integrally molded in an L shape,
The blower 10, the partition plate 11, and the electric component box 12 are placed so that the rear of the top plate 5 of the cabinet 18 integrally formed in an inverted L shape is hooked on the upper portion of the substantially vertical back plate 14. Front surface of the bottom plate 1 of the base plate part 16 and the cabinet part 1
The lower part of the front plate 7 of No. 8 is fitted into a tubular state to fit the left and right lid-shaped side plates 19 and 20 to form an outer shell.

Further, the cabinet structure is such that the bottom plate is flat, the lid-like front plate is fitted to the front part of the U-shaped rear cabinet, and the lid-like top plate is fitted to the upper part of the cabinet. It is disclosed in the official gazette.

[0005]

In the outdoor unit casing constructed as described above, since the lid side plates 19 and 20, the cabinet portion 18 and the base plate portion 16 are engaged with each other, the strength of the casing is weak and the engagement is low. As a result, the workability varies and assembly workability is poor. Further, it is necessary to remove the lid side plates 19 and 20 and the cabinet portion 18 when servicing the unit, and the number of parts to be removed is large. Further, since the base plate is integrally formed in an L-shape, there is a drawback that the work can only be performed from the front and side when assembling the product, the assembling workability is poor, and the cost is increased.

The present invention has been made in order to solve the above-mentioned problems, and has good workability in line assembly, improves the overall strength of the housing, and removes the minimum external parts during servicing. Cheap and easy to work with,
It is intended to provide an outdoor housing.
