[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an air conditioner in which, for example, an electrical component box of an outdoor unit of an air conditioner is securely attached to a partition plate.

[0002]

[Prior art]

 An air conditioner outdoor unit is disclosed in, for example, JP-A-6-159737, and an example thereof will be described with reference to FIGS. 6 and 7. And a heat exchange chamber 5 in which a fan 4 is arranged and a machine room 7 in which a compressor 6 is arranged, and a reactor 8 is mounted on an upper part of the partition plate 2. An electrical component box 11 made of synthetic resin with a radiator plate 10 is provided between the opening portion 9 penetrating the portion 1a. In FIG. 6, reference numeral 1b denotes an opening / closing door for closing the opening 9.

As shown in FIG. 8, the partition plate 2 is made of a steel plate partition plate body 2a bent in a substantially rectangular shape in plan view, and is folded at right angles from both front and rear edges of the partition plate body 2a. The front and rear edge plate portions 2b and 2c are formed by bending the front and rear edge plate portions 2b and 2c and the upper edge plate portion 2d formed by bending the upper edge of the partition plate body 2a at right angles. The lower portion is fixed to the base plate portion 1c of the housing 1 with screws 13 (see FIG. 7), the upper end of the rear edge plate portion 2c is fixed to the housing 1 with screws 14 (see FIG. 8), and the front edge is fixed. The upper end of the plate portion 2b is fixed to a projection 16 integrally projecting from the lower surface 11a of the electrical component box 11 with a screw 17, and the upper edge plate portion 2d is in contact with the lower surface 11a of the electrical component box 11. The front panel 1d of the housing 1 is fixed to the projection 18 integrally projecting from the lower surface 11a of the electrical component box 11 by a screw 19, and is fixed to the lower surface 11a of the electrical component box 11 along the partition plate 2 over substantially the entire width thereof. The waterproof wall 20 is integrally protruded.

In the above configuration, when a drop test is performed, as shown in FIG. 12, the housing 1 is lifted obliquely and dropped from a predetermined height. At this time, the impact force F due to the drop is directly applied to the partition plate 2 which is heavier due to the installation of the reactor 8, and is divided into a longitudinal direction and a transverse direction of the partition plate 2. The impact force F1 is distributed to the bottom of the electrical component box 11 via the upper edge plate portion 2d, so that the electrical component box 11 is not damaged. As a result, the projection 16 is intensively applied to the projection 16 of the electrical component box 11, and the projection 16 may be damaged.

Conventionally, as shown in FIGS. 9 to 11, a substantially U-shaped reinforcing frame 22 made of a steel plate is externally fitted to the projecting portion 16, and an extension piece 22 a integrally extended with the reinforcing frame 22 is provided.

[0006]

[Problems to be solved by the invention]

 In the above-mentioned conventional configuration, the protrusion 16 of the electrical component box 11 is reinforced by the reinforcing frame 22 so as not to be damaged. In this case, the reinforcing frame 22 and the screws 23 for fixing the reinforcing frame 22 are used. As the number of points increases, it takes time and trouble to attach the reinforcing frame 22, and the production cost is high.

[Embodiment of the invention]

 FIG. 1 shows an air conditioner outdoor unit of an air conditioner according to an embodiment of the present invention. A holding member 25 for holding an upper edge portion of a partition plate body 2a on a lower surface 11a of an electrical component box 11 is shown. Are integrally formed. In the configurations other than those described above, the same portions as those shown in FIGS. 6 to 11 are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 2 to FIG. 5, the holding member 25 is integrally protruded over substantially the entire width of the lower surface 11a of the electrical component box 11 with the upper edge plate 2d of the partition plate body 2a interposed therebetween. A pair of ridges 25A, 25B and a plurality of pressing pieces 25a, 25b projecting from inner surfaces of the ridges 25A, 25B at predetermined intervals and abutting on the upper edge plate 2d. At the lower edge of each of the holding pieces 25a, 25b, there is formed an inclined guide surface 26 which is inclined toward the center between the two ridges 25A, 25B.

For the drop test, when the housing 1 is lifted obliquely and dropped from a predetermined height (see FIG. 9), of the impact forces F applied to the partition plate 2 by the drop, the impact force F1 in the longitudinal direction is Since the electric component box 11 is dispersed and applied to the bottom surface of the electric component box 11 via the upper edge plate portion 2d, the electric component box 11 is not damaged, and the impact force F2 in the transverse direction is reduced by the pressing pieces 25a, 25b and It is dispersed and received by the electrical component box 11 via the sandwiching member 25 composed of the ridges 25A and 25B.

Further, even when a transverse impact force F2 is applied to the partition plate 2 which is heavier due to the installation of the reactor 8, the impact force F2 is dispersed via the sandwiching member 25 to disperse the electric component box 11. Therefore, there is no possibility that the transverse impact force F2 concentrates on the fastening portion by the screw 17 and damages the protrusion 16, and the protrusion 16 is replaced with the reinforcing frame 22 as in the related art (see FIG. 11). There is no need to reinforce. Accordingly, the number of components can be reduced by the unnecessary reinforcing frame 22 and the screw 23 for fixing the reinforcing frame 22, and the labor for mounting the component can be reduced, so that the manufacturing cost can be reduced.

Further, since the ridge 25A on the side of the heat exchange chamber 5 also serves as a waterproof wall, the structure of the mold for the electrical component box 11 is simplified by the amount of the role of the waterproof wall, and the mold cost is reduced. Is cheap.
