  Embodiments of the present invention will be described in detail with reference to the drawings as appropriate. In addition, the same code | symbol is attached | subjected to the common part in each figure, and the overlapping description is abbreviate | omitted.

  FIG. 1 is an explanatory diagram of components of the outdoor unit according to the first embodiment. FIG. 2 is an enlarged view of the machine room of the outdoor unit according to the first embodiment. FIG. 3 is a detailed diagram of components of the bottom plate according to the first embodiment. As shown in FIG. 1, the housing of the outdoor unit includes a sheet metal housing such as a bottom plate 1, a front plate 2, a top plate 3, a left side plate 4, and a right side plate 5, and an outdoor heat exchanger 9.

  The machine room 50 includes a bottom plate 1, a front plate 2, a top plate 3, a right side plate 5 and a partition plate 6, and stores a compressor 7. The blower chamber 51 includes the bottom plate 1, the front plate 2, the top plate 3, the left side plate 4, the partition plate 6, and the outdoor unit heat exchanger 9, and stores the outdoor blower 8.

  The air conditioner of the present embodiment also includes an indoor unit (not shown) having an indoor heat exchanger and an indoor blower in addition to the outdoor unit.

  As shown in FIG. 2, an installation leg 11 and a compressor fixing bolt 12 that serve as a foundation at the time of installation are attached to the bottom plate 1, and the compressor 7 is fixed to the compressor fixing bolt 12 via an anti-vibration rubber 13. Yes.

  The partition plate 6 that partitions the machine room 50 and the blower chamber 51 is provided with a bottom plate convex portion through groove 601 as described later.

  The machine room 50 is provided with a bottom plate convex portion 101 and a compressor bottom plate convex portion 105 in order to prevent the bottom plate 1 from being deformed by the weight and driving of the compressor 7. The compressor fixing bolt 12 is installed on the bottom plate convex portion 101 and the compressor bottom plate convex portion 105. Among the bottom plate convex portions 101, the one in the blower chamber 51 is the blower chamber bottom plate convex portion 101a, and the one in the machine chamber 50 is the machine chamber bottom plate convex portion 101b.

  The bottom plate 1 is mainly subjected to an impact load (bending moment by the electrical box 10 via the outdoor fan 8, the outdoor heat exchanger 9, and the partition plate 6) during product transportation or installation transportation. Further, an impact load on the compressor 7 during product transportation or installation transportation is applied to the bottom plate 1 via the compressor fixing bolt 12. Although the bending moment due to the drive of the compressor 7 is also applied to the bottom plate 1, it is smaller than the impact load during product transportation or installation transportation, so the impact load during product transportation or installation transportation against the deformation of the bottom plate 1 Dominant.

  If the bottom plate 1 is reinforced with a plurality of convex portions in the longitudinal direction against an impact load during product transportation or installation transportation, the strength is not enhanced in the bottom plate 1 between the plurality of convex portions. May be deformed.

  Therefore, in this embodiment, two bottom plate projections 101 are continuously formed from the machine chamber 50 to the blower chamber 51 through the partition plate 6 in a direction perpendicular to the installation leg 11. According to the present embodiment, since there is no weakened portion between the blower chamber bottom plate convex portion 101a and the machine room bottom plate convex portion 101b, the bending load due to the weight of the compressor 7, the outdoor heat exchanger 9, and the outdoor blower 8 On the other hand, the deformation of the bottom plate 1 can be suppressed.

  In other words, the bottom plate convex portion 101 has a structure penetrating from the machine room 50 to the blower room 51 in a direction perpendicular to the installation leg 11. The bottom plate convex portion 101 has a blower chamber bottom plate convex portion 101a and a machine chamber bottom plate convex portion 101b, and is formed as one convex portion.

  It is desirable that the height of the bottom plate convex portion 101 is uniform (continuous without a step) from the machine room 50 to the blower room 51, and is linear or broken line. Uniform (continuous without steps) means that there is no large step in the bottom plate convex portion 101, and includes the case where the height of the bottom plate convex portion 101 gradually changes.

  In the present embodiment, the longitudinal direction of the bottom plate 1 refers to a direction perpendicular to the axis of the outdoor fan 8.

  In particular, in the longitudinal direction of the bottom plate 1, the bending moment increases at the bottom plate 1 located between the support portion of the outdoor fan 8 and the support portion of the compressor 7 (compressor fixing bolt 12). In the longitudinal direction of the bottom plate 1, the bottom plate 1 is provided at least between the support portion of the outdoor fan 8 and the support portion (compressor fixing bolt 12) of the compressor 7. That is, the bottom plate convex portion 101 is continuously formed from at least the support portion of the outdoor fan 8 to the support portion (compressor fixing bolt 12) of the compressor 7.

  In addition, in the longitudinal direction of the baseplate 1, it is desirable to provide the baseplate convex part 101 in the whole baseplate 1 between the installation legs 11. FIG. However, since the bending moment is relatively small in the bottom plate in the vicinity of the installation leg 11, it is not necessary to provide the bottom plate convex portion 101 on the entire bottom plate 1 between the attachment legs 11. In the present embodiment, the machine room bottom plate convex portion 101b is configured to straddle the installation leg 11 located on the machine room 50 side, but the blower chamber bottom plate convex portion 101a straddles the installation leg 11 located on the blower chamber 51 side. It is configured without.

  The outdoor heat exchanger 9 of the present embodiment is located between the two installation legs 11 in the longitudinal direction of the bottom plate 1. That is, the outdoor heat exchanger 9 is supported by the two installation legs 11, and the bending moment due to the outdoor heat exchanger 9 is not applied to the bottom plate 1. Therefore, the outdoor heat exchanger 9 is not located on the bottom plate convex portion 101.

  The machine room bottom plate convex portion 101b is provided with a concave portion 102 and a protruding portion 103 in order to prevent deformation of the bottom plate 1 due to the weight and driving of the compressor 7.

  In this embodiment, the bottom plate convex portion 101 is convex upward (convex shape toward the machine chamber 50 and the blower chamber 51), but any other shape can be used as long as it can improve the strength of the bottom plate. Also good. For example, the bottom plate convex portion 101 may be formed in a convex shape downward.

  Dehumidified water generated by cooling with the refrigerant sucked into the compressor 7 during product operation is dropped from the compressor 7 main body onto the machine room bottom plate convex portion 101b. In this embodiment, a step is provided so as to gradually become lower from the machine room bottom plate convex portion 101b toward the drain port 106, and the dehumidified water adhering to the compressor 7 during operation becomes the machine room bottom plate convex portion 101b. Even when it is dropped on the top, it goes to the drain port 106 of the bottom plate 1, so that it can be drained smoothly.

  4 and 5 are explanatory views of the positions of the compressor fixing bolt holes and their reinforcing structures for the purpose of sharing parts according to the first embodiment. In this embodiment, as shown in FIGS. 4 and 5, a plurality of compressors 7 having different dimensions can be mounted only by changing the position of the compressor fixing bolt hole 104, and the bottom plate 1, the compressor fixing bolt 12 and the like. These production facilities are shared.

When the bottom plate is thinned, in addition to a decrease in the strength of the bottom plate 1 itself, the friction of the caulking portion is reduced by the thinned portion, and the fixing strength of the compressor fixing bolt 12 to the bottom plate 1 is reduced.
When an impact load during transportation or installation is applied to the product, the compressor 7 also receives the impact, so that a lateral load is applied to the compressor fixing bolt 12. At this time, if the surface facing the compressor fixing bolt 12 is wide, the bottom plate 1 around the compressor fixing bolt hole is deformed by the load from the compressor 7 applied to the compressor fixing bolt 12, and the compressor fixing bolt There is a possibility that 12 is distorted with respect to the bottom plate. Then, the fixing of the compressor fixing bolt 12 may be loosened, and the compressor 7 may not be driven properly.

  In particular, when a single type of compressor fixing bolt 12 is used in common for a plurality of products having different thicknesses of the bottom plate 1, the compressor fixing bolt hole 104 is deformed particularly in the bottom plate 1 having a thin plate thickness. It's easy to do.

  Therefore, as shown in FIGS. 4 and 5, the machine chamber bottom plate convex portion 101 b is provided with a compressor fixing bolt hole 104 in addition to the concave portion 102 and the protruding portion 103. That is, at least a part of the support portion (compressor fixing bolt 12) of the compressor 7 is located on the bottom plate convex portion 101. According to the present embodiment, since the compressor fixing bolt hole 104 is provided in the machine room bottom plate convex portion 101b of the bottom plate 1 having high strength, deformation of the compressor fixing bolt hole 104 can be suppressed.

  The area of the bottom plate convex portion 101 is increased as the bottom plate convex portion 101 is provided so as to penetrate from the machine room 50 to the blower chamber 51. Then, even if the machine room bottom plate convex portion 101b is provided, there is a possibility that deformation on the surface of the machine room bottom plate convex portion 101b cannot be prevented by an impact load to the compressor 7.

  FIG. 6 is an explanatory diagram of the compressor fixing bolt and the compressor fixing bolt hole according to the first embodiment. FIG. 7 is an enlarged view of the compressor fixing bolt and the compressor fixing bolt hole according to the first embodiment. In this embodiment, as shown in FIGS. 4 to 7, a recess 102 is provided on a machine room bottom plate projection 101 b around the compressor fixing bolt 12.

  According to the present embodiment, the strength of the machine room bottom plate convex portion 101b can be increased, and the strength against the tensile load due to the driving of the compressor 7 can be further increased.

  If the recess 102 interferes with the vibration isolating rubber 13, a sufficient vibration damping effect cannot be obtained, and the diameter of the vibration isolating rubber 13 cannot be freely selected. Therefore, the concave portion 102 is recessed in the opposite direction to the anti-vibration rubber 13 so as not to interfere with the anti-vibration rubber 13.

  When the bottom plate 1 is thinned, the frictional force between the compressor fixing bolt 12 and the bottom plate 1 is lowered, and the fixing to the compressor fixing bolt 12 to the bottom plate 1 may be loosened. Therefore, in the present embodiment, as shown in FIGS. 4 to 6, the machine room bottom plate convex portion 101 b has a protrusion 103 below the support portion (compressor fixing bolt 12) of the compressor 7. In other words, of the machine room bottom plate convex portion 101b, the projection 103 is provided on the joint surface with the support portion (compressor fixing bolt 12) of the compressor 7. According to the present embodiment, when the compressor fixing bolt 12 is caulked, the protrusion 103 is crushed and the frictional force is increased, so that the strength in the rotation direction can be improved.

  In the present embodiment, since the bottom plate convex portion 101 has a structure penetrating from the machine chamber 50 to the blower chamber 51, the partition plate 6 divides the machine chamber 50 and the blower chamber 51 between the bottom plate 1 and the partition plate 6. A gap occurs. Then, rainwater may enter the machine room 50 from the blower room 51 during bad weather, and the compressor 7 and the electric box 10 may be deteriorated.

  Therefore, in this embodiment, as shown in FIG. 1, the bottom plate convex portion 101 has a convex shape upward (convex shape on the machine chamber 50 and blower chamber 51 side), and the partition plate 6 penetrates the bottom plate convex portion 101. A bottom plate convex portion through groove 601 is provided. That is, a part of the bottom plate convex portion 101 is located in the bottom plate convex portion through groove 601. According to the present embodiment, the machine room 50 and the blower room 51 are separated on the partition plate 6 side while suppressing the deformation of the bottom plate 1, and the intrusion of water into the machine room 50 is reduced.

  Further, in order to suppress the generation of sound due to vibration during operation of the compressor 7, a heat insulating sheet is sandwiched between the bottom plate 1 and the partition plate 6. The heat insulating sheet is affixed to either the bottom plate 1 or the partition plate 6. By sandwiching the heat insulating sheet between the bottom plate 1 and the partition plate 6, the amount of rainwater entering from the blower chamber 51 to the machine chamber 50 during bad weather can be suppressed.

  The compressor 7 is generally provided with an S tank (not shown) for performing gas-liquid separation of the return refrigerant on the suction side, and the mass applied to the compressor fixing bolt 12 by this S tank is unbalanced. Become. Then, the amount of crushing of the anti-vibration rubber 13 at two locations in the vicinity of the S tank becomes larger than that at the remaining one location, and the compressor 7 may be inclined and installed on the bottom plate 1. Therefore, the height of the two bottom plate projections 101 on which the compressor fixing bolts 12 are installed may be configured with a difference in height of 1 mm to 2 mm.

  Instead of the bottom plate convex portion 101, the bottom plate 1 may have a bottom plate concave portion having a concave shape on the top (concave shape on the machine chamber 50 and the blower chamber 51 side). In this case, water enters the machine chamber 50 from the blower chamber 51 through a gap (a space between the partition plate 6 and the bottom plate 1) created by providing the bottom plate recess. Therefore, the partition plate 6 is provided with a bottom plate recess projection located in the bottom plate recess. Since the space between the partition plate 6 and the bottom plate 1 can be filled by the bottom plate recess projection, water intrusion into the machine room 50 can be reduced.

  As shown in FIG. 3, the bottom plate 1 may have an uneven shape, and the bottom plate convex portion 101 may be provided on the convex portion of the bottom plate 1.

  The width of the bottom plate convex portion 101 (the length of the bottom plate 1 in the short direction) is preferably narrower than the width of the outdoor heat exchanger 9.

  In the present embodiment, the case where the height of the bottom plate convex portion 101 is uniform from the machine chamber 50 to the blower chamber 51 has been described, but the height may be changed as well as the case where it is not necessarily uniform. For example, for the reason of load balance between the compressor 7 and the S tank (not shown), the height of the bottom plate fan chamber side convex portion 101a may be made higher than that of the bottom plate machine chamber side convex portion 101b.

  In the present embodiment, description of the same components as those in the first embodiment will be omitted. FIG. 8 is a detailed diagram of components of the bottom plate according to the second embodiment. In this embodiment, as shown in FIG. 8, two bottom plate projections 101 are provided, and only one bottom plate projection 101 is provided with a compressor fixing bolt hole 104. That is, the other bottom plate convex portion 101 and the compressor bottom plate convex portion 105 are configured separately.

  The compressor 7 is generally provided with an S tank that performs gas-liquid separation of the return refrigerant on the suction side, and the mass applied to the compressor fixing bolt 12 is unbalanced by the S tank. Then, the amount of crushing of the anti-vibration rubber 13 at two locations near the S tank becomes larger than the remaining one.

  Therefore, the height of the bottom plate convex portion 105 for the compressor located on the outdoor heat exchanger 9 side is set lower than the bottom plate convex portion 101 on which the compressor fixing bolt 12 is installed and the other bottom plate convex portions 105 for the compressor. doing. Furthermore, since the bottom plate convex part 105 for compressors which changed height is comprised with the bottom plate convex part 101 separately, the height of the two bottom board convex parts 101 can be kept at the same height. .

  The height of one compressor bottom plate convex portion 105 independent of the two bottom plate convex portions 101 is the same or only one place is lowered by 1 mm to 2 mm, so that it can cope with the mass unbalance of the compressor 7. It is like that.

  In addition, the baseplate convex part 101 and the baseplate convex part 105 for compressors are each independent, and the height of the baseplate 1 becomes discontinuous. However, the boundary portion is directly above or in the vicinity of the installation leg 11 and is arranged at a position where no stress concentration occurs even when the impact load during the transportation or installation described above occurs.

  The present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.
