An example in which the present invention is applied to an outdoor unit of an air conditioner will be described below with reference to the drawings.
Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiments, and the repetitive description thereof is omitted in principle.
However, the present invention is not construed as being limited to the description of the embodiments below. Those skilled in the art will readily understand that the specific configuration can be changed without departing from the spirit or the spirit of the present invention.

  The structure of the outdoor unit of the air conditioner in the present embodiment is effective in ensuring the rigidity of the housing. In order to clarify the present invention, first, a basic arrangement of a general outdoor unit is shown and the structure is explained.

  FIG. 1 is a diagram showing an appearance of an outdoor unit 100 of a general air conditioner as a comparative example of the present invention. 2 is a side sectional view, and FIG. 3 is a sectional view taken along the line AA in FIG.

  1 to 3, 1a and 1b are maintenance panels, 2a, 2b and 3a and 3b are side panels, 4 is a blower, 41 is a vent cover, 8 is a top plate, 9 is a bottom base, 10 is a housing leg, 11 is a compressor, 12 is an accumulator, 13 is a control panel, 14 is a fixing member, and 15 is a heat exchanger.

  The outdoor unit 100 is provided with a vent hole cover 41 on the top plate 8 on the upper surface of the housing 5, and the blower 4 is mounted therein. The front surface of the housing 5 is covered with maintenance panels 1a and 1b. The side surface and the back surface of the casing 5 are covered with side panels 2a, 2b and 3a, 3b (see FIG. 3). The bottom base 9 of the housing 5 has a structure in which four orthogonal edges are bent upward, and is equipped with a compressor 11, an accumulator 12, and the like. A control panel 13 is attached to a mounting plate (not shown) on the front maintenance panel 1a side.

  The housing 5 of the outdoor unit 100 has side panels 2a, 2a, 2b, as air suction ports for the heat exchanger 15 on a plurality of surfaces other than the surfaces covered by the maintenance panels 1a and 1b, that is, on the left and right sides and the back surface of the housing 5. The heat exchanger 15 is exposed at the openings 6 and 7 (see FIG. 3) between 2b and 3a, 3b. The side panels 2a, 2b and 3a, 3b have a smaller area than the front maintenance panels 1a, 1b in order to widen the openings 6 and 7 as air suction ports.

  The blower 4 is arranged at the upper part of the housing 5 to reduce the influence of other outdoor units (not shown) installed adjacent to each other, and an air suction port between the side panels 2a, 2b and 3a, 3b. The air sucked through the heat exchanger 15 from the openings 6 and 7 is blown out from the vent cover 41 at the top of the housing 5 to the outside.

  Since such an outdoor unit 100 has large openings 6 and 7 between the panels 2a, 2b and 3a, 3b covering the side surfaces and the back surface in order to avoid airflow obstruction to the heat exchanger 15 inside the outdoor unit, As shown in FIG. 4, the rigidity of the housing 5 in the front-rear direction (the direction of the arrow) tends to be low. When the rigidity is low, the casing 5 is likely to resonate due to the vibration source caused by the blower 4 or the compressor 11, and vibration and noise may increase. Therefore, a structure that increases the rigidity of the housing 5 in a range that does not hinder ventilation to the heat exchanger 15 is necessary.

  From the state of deformation of the housing 5 in the front-rear direction shown in FIG. 4, it can be seen that the deformation in the vicinity of the leg 10 greatly contributes to the deformation of the housing 5 in the front-rear direction. Therefore, it is considered that the occurrence of vibration and noise can be suppressed by suppressing the deformation in the vicinity of the leg portion 10 and reducing the deformation amount in the front-rear direction of the housing 5.

  FIG. 5 shows an enlarged view of the circled portion 11 near the end of the leg 10 shown in FIG. The lower leg portion 10 of the housing 5 is structured to be fixed to the gantry 21 and the ground via bolt fastening holes 10a. In FIG. 5, 10a-1 of the leg 10 is a hole for inserting the fork of the forklift when the outdoor unit 100 is transported by the forklift.

  Also in the outdoor unit 100 of the comparative example shown in FIG. 5, in order to increase the rigidity of the housing 5, the side panel 2 a includes a side surface 10 f formed by bending the vicinity of the end of the leg 10 and the side panel 2 a such as a screw. It is connected by a fastening part 51. Further, the bottom base 9 fixed to the upper surface of the leg portion 10 and installed on the equipment such as the compressor 11 and the side panel 2a are similarly coupled by the fastening parts 52 and 53, and the rigidity of the structure at the corner of the housing 5 is obtained. Adopts a structure that enhances. Further, since the side panel 2a fixes the maintenance panels 1a and 1b shown in FIG. 1, there is a folded portion 2a-2 having a slight step on the front side, and from the boundary between the bottom base 9 and the leg 10 In the upper part, there is a turn 2a-1 with a step toward the front side.

  When the rigidity is to be further improved with the above structure, it is necessary to take measures such as increasing the thickness of the leg portion 10 and the side panel 2a, or to add a reinforcing member separately. These methods lead to an increase in cost, and when the latter additional reinforcing material is added, the ventilation to the heat exchanger may be hindered depending on the installation location of the reinforcing member.

  The present invention has been made in view of the above-mentioned problems, and has a structure that can reduce the cost and can ensure the rigidity of the housing in a form that does not inhibit the ventilation of the heat exchanger 15.

  That is, in this embodiment, the amount of deformation in the front-rear direction of the housing 5 is reduced by increasing the rigidity in the vicinity of the leg portion 10 from the state of deformation in the front-rear direction of the housing 5 described in FIG. The generation of noise is suppressed.

  An embodiment of the present invention will be described with reference to FIGS.

Further, the side panel 62-a has holes 651-3 for fastening with the side part 610f of the leg part 610 with the fastening part 651, and holes 652-3 for fastening with the bottom base 69 with the fastening part 652. A hole 653-3 for fastening to the bottom base 69 with a fastening part 653 and a hole 654-3 for fastening to the folded part 610g of the leg 610 with a fastening part 654 are provided in the side turn 62a-1. Each is formed.
The side panel 62a is fixed to two surfaces of the side surface of the bottom base 69 by fastening parts 652 and 653, respectively, and the bottom surface of the side panel 62a is fixed to two surfaces by a leg 610 and connecting parts 651 and 654. The By adopting such a structure, the side panel 62a is more firmly coupled to the bottom base 69 and the leg portion 610, and the rigidity can be increased compared to the structure shown in FIG. 5 described in the comparative example. Further, by making the height H of the turn 610g and the dimension D from the end portion 610c of the leg 610 to the turn portion 610g small, it is possible to produce the portion of the turn portion 610g only by turning back part of the end portion 610c. In view of the unfolded dimensions of the leg 610 before bending, the amount of material used is not increased, and the cost is excellent.

  The portion of the folded portion 2a-2 at the lower front side of the side panel 2a in the comparative example described with reference to FIG. 5 needs to be molded by cutting out the difference from the width of the folded portion 2a-1 at the upper portion from the square plate material.
