Since the conventional outdoor unit is constructed as described above, the auxiliary base has a low strength for placing heavy parts on the auxiliary base and cannot be effectively used as a base. Also, the installation of the rear panel causes assembly distortion,
Insufficient strength of the entire housing occurs. There is also a problem that the number of parts of the auxiliary base itself is increasing. In addition, when the indoor unit and the refrigerant extension pipe are taken in, the left pipe has no internal storage space, is an external pipe, and has a problem in that the appearance is poor in design. Further, there is a problem that the dew condensed on the accumulator and other pipes remains on the base as it is and is not discharged, so that corrosion of the base is accelerated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it has been made possible to increase the strength of the housing constituting the outdoor unit, the strength of the base, and the expansion of the effective space without impairing the workability. It is an object of the present invention to reduce the number of parts, improve the design of installation, and provide a product with good quality.
