DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below in detail with reference to the drawings. FIG. 1, FIG. 2 (A) and FIG. 2 (B)
And 1, a bottom plate constituting an outdoor unit main body of the air conditioner, 2 a heat exchanger mounted on the bottom plate 1, 3 a fan motor provided opposite to the heat exchanger 2, 4 The motor mounting base 5 for mounting the fan motor 3 is provided with a suction port facing the heat exchanger 2, and is provided with a joining portion 5a for joining to a front cover (not shown) made of synthetic resin. A synthetic resin rear cover attached to the bottom plate 1;
Reference numeral 6 denotes a screw for screwing an upper mounting portion of the motor mounting base 4 to a boss described later provided on the rear cover 5, and reference numeral 7 denotes a band-shaped seal provided on the upper part of the heat exchanger 2 for wind shielding. It is a member.

A lower mounting portion of the motor mounting base 4 is fixed to the bottom plate 1 by screwing or the like, and an insertion hole 4b is provided in the upper mounting portion, and a screw hole is formed in the rear cover 5 opposed to the insertion hole 4b. The upper mounting portion is fixed to the rear cover 5 by screwing the upper mounting portion to the screw hole of the boss portion with the screw 6 inserted through the insertion hole 4b. Thus, the motor mounting base 4 can be mounted from the front side, and the rear cover 5 can be easily removed from the front side without removing the rear cover 5 from the bottom plate 1 at the time of removal. Configuration.

The boss portion is composed of a hanging piece c hanging from the upper surface of the rear cover 5 and a boss 5c standing substantially perpendicularly to the hanging piece c. The sink piece c and the boss 5c can be integrally formed so as not to cause sink marks on the upper surface of the fifth piece 5.

The boss 5c, the hanging piece c, and the upper surface of the rear cover 5 are connected to each other by a rib d so that the strength of the boss can be increased.

A rearward flange 4a is provided on both sides of the motor mount 4, and a guide 5b connected to the hanging piece c of the boss portion is provided on both sides of the boss 5c corresponding to the flange 4a. Is provided, the flange 4a can be easily positioned along the guide 5b, so that the screw 6 inserted through the insertion hole 4b can be connected to the boss 5c.
It can be easily screwed into the screw hole.

Further, the front ends of the boss 5c and the guide 5b are formed substantially flush, so that the motor mount 4
The upper mounting portion of the device can be accurately mounted.

Further, since the boss portion, the rib d, and the guide 5b are formed integrally with the rear cover 5, the dimensions and shape can be finished with high accuracy, and the configuration is advantageous in cost.

With the above structure, as shown in FIGS. 1, 2A and 2B, the lower mounting portion of the motor mounting base 4 is fixed to the bottom plate 1 by screwing or the like. At the same time, an insertion hole 4b is provided in the upper mounting portion, and a boss portion comprising a boss 5c having a screw hole is provided in the rear cover 5 facing the insertion hole 4b, and the upper mounting portion is connected to the screw hole of the boss portion. The motor mounting base 4 can be easily mounted from the front side by fixing the motor mounting base 4 to the rear cover 5 by screwing the insertion hole 4b through the insertion hole 4b with the screw 6. Thus, the outdoor unit of the air conditioner can be easily removed without removing the rear cover 5.
