Unexamined-Japanese-Patent No. 2007-309632

  In the outdoor unit of the air conditioning apparatus described in Patent Document 1, the heat exchanger is arranged in a substantially U-shape or a substantially B-shape to increase the surface area of the heat exchanger. In order not to block the air flow for taking in the outside air of the heat exchanger arranged in this way, there are large opening portions on the side surfaces except the front side and the back surface. Because of this, the strength and rigidity are likely to be reduced by the opening, which also affects vibration and noise. However, the addition of a reinforcing member for this improvement causes an increase in cost due to an increase in the number of parts and an increase in the amount of material used. In addition, if there is a reinforcing member in the vicinity of the heat exchanger, it is not preferable because it becomes an obstacle to air flow.

  The present invention solves the above-described problems of the prior art, and suppresses the cost increase factor and the air flow inhibition factor while securing the vibration, noise and reliability of the outdoor unit. An outdoor unit of an air conditioner having a structure capable of enhancing the strength and the rigidity.

And each is configured to be fastened by a fastening member.

  Further, in order to solve the above-mentioned problems, in the present invention, a housing for mounting a fan and mounting a compressor and a heat exchanger on a bottom base, and a leg portion on which the bottom base is mounted and fixed to a ground surface In the outdoor unit of an air conditioner or refrigerator including a side cover that covers the side of the housing, the side cover has a shape that bends near the end to cover a part of the front of the housing, The cover is configured such that the surface covering the side of the housing and the surface that is bent to cover a part of the front of the housing are fastened by fastening members to the bottom base and the legs, respectively.

  According to the present invention, the rigidity and the strength of the housing can be improved with almost no additional parts added to the housing of the outdoor unit, and the strength and the rigidity can be improved without increasing the factor for inhibiting the ventilation. In addition, the cost is excellent because almost no additional parts are required. The details of the configuration and effects will be clarified by the description of the embodiments below.

The example which applied this invention to the outdoor unit of an air conditioning apparatus is demonstrated using drawing using the following.
Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted in principle.
However, the present invention should not be construed as being limited to the description of the embodiments below. Those skilled in the art can easily 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 conditioning apparatus in the present embodiment is effective in securing the rigidity of the housing. In order to clarify the present invention, first, a basic arrangement of a general outdoor unit will be shown, and the structure will be described.

  FIG. 1: is a figure which shows the external appearance of the outdoor unit 100 of a general air conditioning apparatus as a comparative example of this invention. FIG. 2 is a side sectional view, and FIG. 3 is a sectional view taken along line AA in FIG.

  In the configuration shown in FIGS. 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 casing 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.

  In the outdoor unit 100, a vent cover 41 is provided on the top plate 8 on the upper surface of the housing 5, and the blower 4 is mounted therein. In addition, the front surface of the housing 5 is covered with maintenance panels 1a and 1b. The side surfaces and the back surface of the housing 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 the edges of four orthogonal turns are bent upward, and the compressor 11 and the accumulator 12 are mounted. Further, on the side of the front maintenance panel 1a, a control panel 13 is attached to a mounting plate (not shown).

  The casing 5 of the outdoor unit 100 is a side panel 2a, which serves as an air suction port of the heat exchanger 15 at a plurality of locations, such as the left and right sides and the back of the casing 5, other than the surface covered by the maintenance panels 1a and 1b. 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.

  Further, the blower 4 is disposed 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 intake 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.

  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 the air flow blockage to the heat exchanger 15 inside the outdoor unit, As shown in FIG. 4, the rigidity in the front-rear direction (direction of the arrow) of the housing 5 tends to be low. When the rigidity is low, the housing 5 tends to resonate due to the vibration source caused by the blower 4 and the compressor 11, and the vibration and noise may increase. Therefore, the structure which raises the rigidity of the housing | casing 5 in the range which does not inhibit the ventilation to the heat exchanger 15 is required.

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

  FIG. 5 is an enlarged view of a circled portion 11 near the end of the leg 10 shown in FIG. 4. The lower leg portion 10 of the housing 5 is fixed to the gantry 21 and the ground via a bolt fastening hole 10a. In addition, in FIG. 5, 10a-1 of the leg part 10 is a hole for inserting the fork of a forklift, when conveying the outdoor unit 100 with a 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 2a is formed by bending the vicinity of the end of the leg 10 and the side panel 2a is a screw or the like It is connected by the fastening part 51. Furthermore, the bottom base 9 fixed to the upper surface of the leg 10 and mounting the device 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 Has a structure that In addition, in order to fix the maintenance panels 1a and 1b shown in FIG. 1, the side panel 2a has a folded back portion 2a-2 slightly stepped on the front side, and from the boundary between the bottom base 9 and the leg 10 In the upper part, a turn 2a-1 with a step toward the front side is present.

  In order to further improve the rigidity 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 separately add a reinforcing member. These methods lead to an increase in cost, and when the latter additional reinforcing material is added, depending on the installation location of the reinforcing member, the ventilation to the heat exchanger may be inhibited.

  The present invention has been made in view of the above-described problems, and has a structure that can suppress the cost and can ensure the rigidity of the case without blocking the air flow to the heat exchanger 15.

  That is, in the present 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. It is intended to suppress the generation of noise.

  An embodiment of the present invention will be described with reference to FIGS. The configuration shown in FIGS. 6 to 10 is a view corresponding to the configuration shown in FIG. 5 described as the comparative example, and the other portions are the same as the configurations described in FIGS. 1 to 3. Description is omitted because it exists. That is, the cross-sectional view of the side surface of the outdoor unit in the present embodiment is the same as that described in FIG. 2, and the configuration shown in FIG. 3 which is a sectional view taken along line AA in FIG. It is the same as the configuration of the outdoor unit in.

  In the present embodiment, as shown in FIG. 6, the side of the side panel 62a is fixed by the bottom base 69, the side portion 610f of the leg portion 610, and the fastening part 651 in the case of the comparative example described in FIG. In the same manner as in the above, except that folds 610g are provided at both ends of the leg 610, the fold 62a-1 on the front side of the side panel 62a is extended to the lower part, and the leg fold 610g can be coupled with the fastening part 654. I assume. Further, the side panel 62b partially shown in FIG. 6 is formed with a back surface side folded portion having the same shape as the side panel 2b of FIG. 3 shown in the comparative example.

  FIG. 7 shows the appearance of the leg 610 alone. The leg portion 610 bends one plate in a U-shape to form a bottom surface 610d in contact with the ground contact surface and a top surface 610e on which the housing 5 is placed, and a rising surface 610b sandwiched between the bottom surface 610d and the top surface 610e Side portions 610f folded inward are formed on both sides. Furthermore, in the vicinity of the side surface portion 610f formed on both sides, a part of the bottom surface 610d on the side of the end surface 610c is folded upward to form a folded portion 610g in a direction substantially orthogonal to the side surface portion 610f. The side surface portion 610 f is formed with a hole 651-1 for fastening the side component 62-a with the fastening component 651.

  In FIG. 8, a bottom base 69 which is formed into a box shape by bending the end portions of the four circumferences is placed on the upper surface 610e of the pair of leg portions 610 by a fixing means such as a bolt not shown. It shows the fixed state. On the side surface of the bottom base 69, holes 652-2 for fastening the front side of the side panel 62-a with the fastening part 653 and the side panel 62-a with the fastening part 652. Hole 652-2 is formed. Here, the surface of the bottom base 69 in which the hole 653-3 is formed is on the same plane as the surface of the leg 610 in which the folded portion 610g is formed, and the hole 653-2 of the bottom base 69 is formed. The side surface of the leg portion 610 is on the same plane as the side surface 610 f of the leg portion 610.

  FIG. 9 shows a perspective view of a portion to be fixed to the leg portion 610 and the bottom base 69 of the side panel 62-a. The side panel 62-a is once folded back to form an end face 62a-2, and the side panel 62-a is folded back again to form a face 62a-1. Maintenance panels 1a and 1b are attached on the surface 62a-1.

As shown in FIG. 9, in the portion to be fixed to the leg portion 610 of the side panel 62-a, the lowermost portion is formed to have the same length as the lowermost side of the front side fold 62a-1. There is. Further, the side panel 62-a has a hole 651-3 for fastening the side part 610 f of the leg 610 with the fastening part 651, and a hole 652-3 for fastening with the bottom base 69 with the fastening part 652. Holes 653-3 for fastening to the bottom base 69 with the fastening parts 653 in the side folding 62a-1 and holes 654-3 for fastening with the folding part 610g of the leg 610 with the fastening parts 654 Each is formed.
Also, the side panel 62a is fixed at its two sides to the two sides of the bottom base 69 by the fastening parts 652 and 653, respectively, and the lower side of the side panel 62a is fixed at its two sides by the leg portion 610 and the connecting parts 651 and 654. Ru. With such a structure, the side panel 62a is more firmly connected to the bottom base 69 and the leg portion 610, and rigidity can be enhanced as compared with the structure shown in FIG. 5 described in the comparative example. Also, by reducing the height H of the folded back 610g and the dimension D from the end 610c of the leg 610 to the folded back 610g, it is possible to produce the folded back portion 610g by folding only part of the end 610c. When viewed in the unfolded size before bending of the leg portion 610, the amount of material used is not large, and the cost is excellent.

  It is necessary to cut out and shape the difference between the folded portion 2a-1 of the upper portion from the rectangular plate material and the portion of the folded portion 2a-2 on the front side lower portion of the side panel 2a in the comparative example described in FIG. The On the other hand, in the structure of this embodiment shown in FIG. 6, since the width dimension of the front folded portion 62a-1 of the side panel 2a is constant up to the lower end, unnecessary cutting is not necessary. Also excellent in processing process.

  The connection between the side panel 62a and the bottom base 69 and the leg 610 has been described above, but the side panel (not shown) (corresponding to the side panel 3a in FIG. 3) and the bottom base arranged at a position facing the side panel 62a The connection between the arm 69 and the leg 610 is the same as in the case of the side panel 62a described above, so the description will be omitted.

  In the configuration described in FIG. 7, the rising surface 610b of the leg portion 610 is folded back to form the side portion 610f, but as shown in FIG. 10, the side surface portion 610f is raised from the bottom surface 610d of the leg portion 610-1. You may form. In the leg 610-1 shown in FIG. 10, the portions given the same reference numerals as the legs 610 described in FIG. 7 are the same as those described in FIG.

  According to the present embodiment, the side panel 62a can be fixed to the bottom base 69 and the leg portion 610 in two planes, respectively, and the rigidity of the side panel 62a in the front-rear direction of the housing 5 can be enhanced. . As a result, generation of vibration and noise when the outdoor unit 100 is operated can be suppressed as compared with the conventional structure shown in the comparative example.

  Further, the improvement in rigidity and strength that is caused by fastening the leg folding back 610g with the side panel 62a can be used to shorten the width of the side panel 62a. That is, the width W2 of the portion of the side panel 62a in the present embodiment shown in FIG. 6 extending to the side of the leg 610 extends to the side of the leg 10 of the side panel 2a in the comparative example described in FIG. It is also possible to set W1> W2 as compared with the width W1 of. As a result, the opening on the side surface of the outdoor unit casing can be widely taken, the ventilation resistance to the heat exchanger can be improved, and the conversion efficiency of the heat exchanger can be improved.

  Therefore, according to the present embodiment, it is possible to obtain an outdoor unit capable of improving the rigidity and reducing the ventilation resistance while suppressing the cost.

  In addition, although the example demonstrated above demonstrated the example of the outdoor unit of the air conditioner, this invention is not limited to this, It is applicable also to the outdoor unit of a refrigerator.
