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 of an air conditioner disclosed in, for example, 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 denotes 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. Reference numeral 5 denotes a top plate, and reference numeral 7 denotes a front plate provided with an outlet 17. The front panel 7 and the top panel 5 are integrally formed in an inverted L-shape to form a cabinet section 18. And the base plate portion 16
And the cabinet 18 are engaged with each other to form a cylindrical body whose both sides are opened, and the openings on both sides are closed by lid-like side plates 19 and 20, respectively, to form a housing.

Next, the operation will be described. The compressor 8, the heat exchanger 9, and the compressor 8 of the bottom plate 1 of the base plate portion 16 are integrally formed in an L shape.
The blower 10, the partition plate 11, and the electric component box 12 are placed, and the rear of the top plate 5 of the cabinet portion 18 integrally formed in an inverted L shape is hooked on the upper portion of the substantially vertical back plate 14. The front of the bottom plate 1 of the base plate 16 and the cabinet 1
The outer shell is formed by fitting the lower part of the front plate 7 of 8 into a cylindrical state by fitting the left and right lid-like side plates 19 and 20.

Japanese Unexamined Utility Model Publication No. 58-104865 discloses a cabinet structure in which a bottom plate is flattened, a lid-shaped front plate is fitted to a front portion of a U-shaped rear cabinet, and a lid-shaped top plate is fitted to an upper portion of the cabinet. It is disclosed in the gazette.

[0005]

In the outdoor unit housing configured as described above, the lid-shaped side plates 19 and 20, the cabinet portion 18 and the base plate portion 16 are engaged with each other, so that the strength of the housing is weak and the engagement is made. The work condition varies due to the variation in the above, and the assembling workability is poor. Further, it is necessary to remove the lid-like side plates 19 and 20 and the cabinet part 18 when the unit is serviced, and the number of parts to be removed is large. In addition, since the base plate is integrally formed in an L-shape, only work from the front and the side can be performed at the time of assembling the product, so that the assembling workability is poor and the cost is increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has improved line assembling operability, improves the overall strength of the housing, and removes a minimum number of outer parts during service. Inexpensive and good workability,
It is an object to provide an outdoor housing.
