BEST MODE FOR CARRYING OUT THE INVENTION Hereinbelow, the outdoor unit of the air conditioner in the present invention will be described in detail in the embodiments thereof with reference to the accompanying drawings.
First Embodiment Fig. 1 is an exploded perspective view showing an outdoor unit of an air conditioner in the first embodiment of the present invention. As shown in Fig. 1, on a bottom plate 1, there is mounted a one-piece plastic casing front 2 forming a front plate 2a, a top plate 2b and a side plate 2c. A bellmouth 3 is attached to the casing front 2, and a side plate 4 is attached to the right side of the casing front 2. A partition plate 5 is attached inside the casing front 2, the partition plate 5 being generally parallel to the side plate 4 with certain spacing therefrom. A rear 4a extending to the partition plate 5 is provided on the rear end of the side plate 4. A side cover 6 is placed on the external side face of the side plate 4. Between the side plate 4 and the partition plate 5, there is formed a machine chamber for accommodating a compressor 7, an accumulator 8, an electrical equipment box (unshown) and the like. A lower end of a motor supporting member 11 is fixed to the bottom plate 1, while an upper end of the motor supporting member 11 is fixed to the top plate 2b side of the casing front 2. A motor 10 is attached to the motor supporting member 11 so that an output shaft would be generally parallel. An air fan 9 is attached to the output shaft 10a of the motor 10. An generally L- 6 shaped heat exchanger 12 is disposed on the rear side of the motor supporting member 11 inside the casing front 2 and in the vicinity of the side plate 2c inside the casing front 2. Further, on the rear side of the heat exchanger 12, there is mounted a ladder-shaped protection member 13 for protecting the heat exchanger 12.
Fig. 2 is an exploded perspective view showing a casing front 2 and a bellmouth 3 of the outdoor unit of the air conditioner. As shown in Fig. 2, the casing front 2 is provided with a front plate 2a having a circular outlet 14, a top plate 2b extending with an generally right-angled curve from the top end of the front plate 2a, and a side plate 2c extending with an generally right-angled curve from the side end of the front plate 2a. The bellmouth 3 is attached to the rear side of the front plate 2a without using screws (unshown). A reinforcing member 15 having an generally L shape cross section is attached to the rear side of the side plate 2c without using screws (unshown) The reinforcing member 15 is attached to the side plate 2c because placing a reinforcing flange on the rear side of the side plate 2c is not applicable due to restrictions relating to molding.
Thus, in the outdoor unit of the air conditioner according to the present invention, the one-piece casing front 2 is formed by integrating the front plate 2a, the top plate 2b and the side plate 2c shown in Fig 2, which makes it possible to reduce the number of components especially in the case where the rear plate is not used for reducing passing resistance of air taken in from the rear side, thereby improving assembling efficiency and achieving cost reduction.

The outdoor unit of the air conditioner in the second embodiment has the same structure as the outdoor unit of the air conditioner in the first embodiment except the casing front.
As shown in Fig. the casing front 10 is provided with an generally L-shaped member 16 formed through integral molding of a front plate 16a having a circular outlet 17 and a top plate 16b extending with an generally right-angled curve from the top end of the front plate 16a, and a side plate 18 attached to the side end of the front plate 16a of the generally L-shaped member 16 with using screws (unshown). A bellmouth 3 is attached to the front plate 16a of the casing front 10. Thus, as shown in Fig. the front plate 16a, the top plate 16b, and the side plate 18 are integrated to form the casing front The outdoor unit of the air conditioner with use of the casing front 10 has the same effect as the outdoor unit of the air conditioner in the first embodiment.
Furthermore, attaching the side plate 18 of the casing front 10 to the generally L-shaped member 16 formed through integral molding of the front plate 16a and the top plate 16b makes it possible to simplify a mold compared to the case of molding the three-face one-piece structure with the front plate 16a, the top plate 16b and the side plate 18 being integrated.
Although the side plates 2c and 18 are placed on the left side of the casing fronts 2 and 10 in the first and second embodiments, the side plate may obviously be placed on the right side of the casing front.
Also, although the bellmouth 3 is provided on the casing fronts 2 and 10 in the first and second embodiments, the bellmouth may be formed on the front plate of the casing front, which implements further reduction of the number of components, thereby achieving further improvement of assembling efficiency.
