[0001] The present invention relates to an accumulator mounting base for mounting an accumulator to a housing of an outdoor unit, and an outdoor unit of an air conditioner equipped with the same. [Background technology]
[0002] An outdoor unit of an air conditioner is equipped with an accumulator connected to the intake side of the compressor. A commonly known structure is one in which the accumulator is fixed to a support member that serves as a mounting base, and the support member is installed on the bottom plate of the outdoor unit housing.
[0003] For example, Patent Document 1 discloses an accumulator support member that has a generally U-shaped overall shape when viewed from the side, and that includes a flat upright portion that stands up from the bottom plate of a housing, first and second arms that are made of flat members provided on the upper end side of the upright portion and support the bottom of the accumulator, and first and second feet that are made of flat members provided at an interval on the lower end side of the upright portion and are fixed to the bottom plate of the housing. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Patent Publication No. 2010-175138 Summary of the Invention [Problem to be solved by the invention]
[0005] However, in the support member described in Patent Document 1, the surface facing the upright portion is open, and the accumulator is supported by only a single upright portion. Therefore, for example, if the outdoor unit is accidentally dropped during transportation, the support member may be deformed by impact. If the support member is deformed, the refrigerant piping connected to the accumulator may be damaged, or the refrigerant piping and wiring routed in the space between the flat plate-like members above and below the support member may be damaged. Furthermore, the accumulator vibrates due to vibration of the compressor during operation. If the support member is not strong enough, the accumulator may vibrate, causing noise and other problems.
[0006] In view of the above circumstances, an object of the present invention is to provide an accumulator mounting base that can increase the strength of the support member of the accumulator against deformation, and an outdoor unit of an air conditioner that includes the same. [Means for solving the problem]
[0007] An accumulator mount according to one aspect of the present invention is an accumulator mount for mounting an accumulator to a bottom plate of an outdoor unit of an air conditioner, comprising: The accumulator has a mounting portion on which the accumulator is placed, a fixed portion fixed to the bottom plate, a first upright portion that stands up against the bottom plate and connects one end of the mounting portion to one end of the fixed portion, and a second upright portion that stands up against the bottom plate and connects the other end of the mounting portion to the other end of the fixed portion.
[0008] The second standing portion may be detachably connected to the placing portion and the fixing portion.
[0009] The second upright portion may have a first portion and a second portion inclined at a predetermined angle relative to the first portion. The other end of the fixing portion may have a first bent portion bent to stand up relative to the bottom plate and a second bent portion bent at the predetermined angle relative to the first bent portion, and when the second upright portion is connected to the other end of the fixing portion, the second portion may be overlapped on the second bent portion.
[0010] The second portion may have a claw portion cut and raised toward the fixing portion. The second bent portion may have a fitting hole into which the claw portion fits when the second bent portion is placed on top of the second portion.
[0011] The mounting portion may have a mounting surface on which the accumulator is mounted, and an assembly surface on which the second upright portion is assembled, the assembly surface being formed by bending an end of the mounting surface on the second upright portion side as the other end of the mounting portion. The assembly surface may have a pair of first positioning protrusions facing each other so as to sandwich both side ends of the second upright portion therebetween.
[0012] The mounting surface may have a pair of second positioning protrusions that face each other and sandwich a leg that is provided on the bottom of the accumulator and that fixes the accumulator to the mounting portion.
[0013] An outdoor unit of an air conditioning apparatus according to one embodiment of the present invention includes an accumulator, a housing having a bottom plate that houses and supports the accumulator, the above-mentioned accumulator mounting base that attaches the accumulator to the bottom plate, and a connection valve that is disposed inside the housing and is connected to a refrigerant pipe that is connected to an indoor unit. The refrigerant pipe passes through a hollow portion formed among the mounting portion, the fixing portion, the first upright portion, and the second upright portion of the accumulator mounting base.
[0014] The housing may have a side portion that is positioned opposite the second upright portion of the accumulator mounting base and has an opening that exposes the second upright portion to the outside, and a lid portion that is removably attached to the side portion and closes the opening. [Effects of the Invention]
[0015] According to the present invention, the strength of the support member of the accumulator against deformation can be increased. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0018] Figures 1 and 2 show the entire outdoor unit 100 of an air conditioner according to one embodiment of the present invention, with Figure 1 being a perspective view from the front side and Figure 2 being a perspective view from the rear side. Figure 3 is a plan view showing the internal structure of the outdoor unit 100. In each figure, the X-axis, Y-axis, and Z-axis indicate three orthogonal axial directions, with the X-axis corresponding to the front-rear direction, the Y-axis corresponding to the left-right direction, and the Z-axis corresponding to the height direction.
[0019] [Outline of the outdoor unit] The outdoor unit 100 is connected to an indoor unit (not shown) via refrigerant pipes L1, L2 (see FIG. 4). The outdoor unit 100 is equipped with a metal housing 10 that forms the outer shell of the outdoor unit 100. As shown in FIG. 3, the housing 10 has an internal space 10s that is divided into a heat exchange chamber 1 and a machine chamber 2 by a partition plate 3. A heat exchanger (outdoor heat exchanger) 4, an outdoor fan 5, and the like are arranged in the heat exchange chamber 1. In the machine chamber 2, a compressor 6, an accumulator 7, and an electrical unit (not shown) that is equipped with various electronic components that control each part of the outdoor unit 100 are arranged.
[0020] As shown in FIGS. 1 and 2, the housing 10 has a top panel 11, a heat exchange chamber front panel 12, a machine chamber front panel 13, a machine chamber rear panel 14, side panels 15, and a bottom plate 16.
[0021] The top panel 11 forms the top surface of the housing 10, and the bottom panel 16 forms the bottom surface of the housing 10. The heat exchange chamber 1 is formed by the partition plate 3, the top panel 11, the heat exchange chamber front panel 12, the side panels 15, and the bottom plate 16. The machine chamber 2 is formed by the partition plate 3, the top panel 11, the machine chamber front panel 13, the machine chamber rear panel 14, and the bottom plate 16. The machine chamber front panel 13 has an upper front panel portion 13a and a lower front panel portion 13b, and the machine chamber rear panel 14 has an upper rear panel portion 14a and a lower rear panel portion 14b.
[0022] The heat exchange chamber 1 draws external air into the housing 10 through intake ports (not shown) provided on the rear side and side panel 15 of the housing 10. The external air exchanges heat with a refrigerant in the heat exchanger 4, and is then blown out to the front side through an outlet (not shown) on the heat exchange chamber front panel 12. A fan guard 12G is provided on the heat exchange chamber front panel 12 to cover the outlet. As shown in FIG. 3, the heat exchanger 4 has an L-shaped planar shape that bends from the rear of the heat exchange chamber 1 toward the inside of the side panel 15. The heat exchanger 4 covers almost the entire rear surface of the heat exchange chamber 1 and is exposed to the outside through a rectangular intake port formed between the top panel 11, the bottom plate 16, the machine room rear panel 14, and the side panel 15, as shown in FIG. 2.
[0023] The compressor 6 and accumulator 7 arranged in the machine room 2 are installed on a bottom plate 16. Figure 4 is a side cross-sectional view of the main part of the outdoor unit 100 showing the lower part of the machine room 2 with the machine room front panel 13 and the machine room rear panel 14 removed, and Figure 5 is a perspective view of the part shown in Figure 4 as seen from the front side.
[0024] As shown in Fig. 4, the accumulator 7 is mounted on the bottom plate 16 of the housing 10 via an accumulator mounting base 50 (hereinafter also simply referred to as the mounting base 50). In this embodiment, the accumulator 7 is installed in a corner on the side of the machine room rear panel 14, as shown in Fig. 4. The mounting base 50 is a support member that supports the accumulator 7, and is formed of a metal frame body such as a galvanized steel plate having a hollow portion 50s, as will be described later.
[0025] The machine chamber 2 is further provided with a first connection valve 31 connected to the refrigerant pipe L1 and a second connection valve 32 connected to the refrigerant pipe L2. The first connection valve 31 and the second connection valve 32 are used to connect the refrigerant circuit of the outdoor unit 100 to the refrigerant circuit of an indoor unit (not shown) via the refrigerant pipes L1 and L2, with the refrigerant pipe L1 corresponding to a gas pipe and the refrigerant pipe L2 corresponding to a liquid pipe. The refrigerant pipes L1 and L2 are routed along the bottom of the machine chamber 2 and can be pulled out to the front, right side, or rear side. When pulled out to the rear side, for example, they are pulled out to the outside of the outdoor unit 100 through insertion holes 141 and 142 (see FIG. 2) provided in the hollow portion 50s of the mounting base 50 and the lower rear panel 14b.
[0026] [Accumulator mounting base] Next, details of the mounting base 50 will be described. Fig. 6 is a perspective view showing the relationship between the mounting base 50 and the accumulator 7 supported thereon, as viewed from the bottom plate 16 side, and Fig. 7 is a perspective view showing the entire mounting base 50.
[0027] The mounting base 50 has a placing portion 51, a fixing portion 52, a first upright portion 53, and a second upright portion 54. The placing portion 51, the fixing portion 52, and the first upright portion 53 form each surface of the mounting base main body 50A, which is formed by bending a metal plate such as a galvanized steel plate into a substantially U-shape. The second upright portion 54 is formed by bending a metal plate such as a galvanized steel plate into a predetermined shape, and functions as a reinforcing member that is detachable from the mounting base main body 50A, as described below. The internal space surrounded by the placing portion 51, the fixing portion 52, the first upright portion 53, and the second upright portion 54 is the hollow portion of the present invention (hollow portion 50s in FIG. 7).
[0028] 8 is a perspective view of the mount body 50A, FIG. 9 is a perspective view of the second standing portion 54, and FIG. 10 is a side view of the mount body 50A with the second standing portion 54 attached, as seen from the front side.
[0029] (Placement section) The mounting portion 51 is a substantially rectangular plate portion having a mounting surface 510 parallel to the XY plane. One end of the mounting portion 51 in the Y-axis direction is formed continuously with the first upright portion 53, and the other end in the Y-axis direction has the second upright portion 53 fixed thereto.
[0030] A pedestal 70 fixed to the bottom of the accumulator 7 is placed on the placement surface 510 (see FIG. 5). The pedestal 70 is used to fix the accumulator 7 to the placement portion 51, and is fixed to the bottom of the accumulator 7 by welding or the like.
[0031] An opening 510A facing the center of the foot stand 70 and a pair of opening grooves 510B facing each other in the X-axis direction with the opening 510A in between are provided in the center of the mounting surface 510. The opening grooves 510B have a slot shape extending in the Y-axis direction, and when the accumulator 7 is installed on the mounting base 50, the pair of legs 70B protruding from the bottom of the foot stand 70 fit into the pair of opening grooves 510B (see FIG. 6).
[0032] The mounting portion 51 further has an assembly surface 511 (see FIG. 8). The assembly surface 511 is formed by bending the other end of the mounting surface 510 toward the fixing portion 52 by approximately 90 degrees. The assembly surface 511 is provided with a pair of first screw holes 511A through which screws N1 (see FIG. 7) for fastening to the upper end of the second upright portion 54 are inserted, and a second screw hole 511B through which screws N3 for fastening to a fixing piece 70A (see FIGS. 4 and 6) formed on the end of the base 70 are inserted. The second screw hole 511B is provided in approximately the center of the assembly surface 511, and the pair of first screw holes 511A are provided on both sides of the assembly surface 511 in the X-axis direction so as to sandwich the second screw hole 511B therebetween.
[0033] The assembly surface 511 has a pair of first protrusions (first positioning protrusions) 512 that face each other and sandwich both sides in the X-axis direction of the second upright portion 54. The first protrusions 512 are formed by bending both ends of the assembly surface 511 in the X-axis direction outward by approximately 90 degrees in the Y-axis direction. The first protrusions 512 have the function of positioning the second upright portion 54 in the X-axis direction with respect to the assembly surface 511 when the second upright portion 54 is assembled to the assembly surface 511, and the spacing dimension of the first protrusions 512 in the X-axis direction corresponds to the width dimension of the second upright portion 54.
[0034] The mounting portion 51 further has a pair of second protrusions (second positioning protrusions) 513 that face each other and sandwich the foot stand 70 in the X-axis direction. The second protrusions 513 are formed by bending both ends of the mounting surface 511 in the X-axis direction upward by approximately 90 degrees in the Z-axis direction. The second protrusions 513 have the function of positioning the foot stand 70 in the X-axis direction with respect to the mounting portion 51 when the foot stand 70 of the accumulator 7 is assembled to the mounting portion 51, and also have the function of increasing the bending strength of the mounting portion 51, and the spacing dimension of the second protrusions 513 in the X-axis direction corresponds to the dimension of the foot stand 70 in the X-axis direction.
[0035] (fixed part) The fixing portion 52 is a substantially rectangular plate portion having a fixing surface 520 parallel to the XY plane and facing the placement surface 510 in the height direction (Z-axis direction). The fixing surface 520 is fixed onto the bottom plate 16. The fixing surface 520 is provided with an opening 520A that engages with a positioning protrusion 16B (see FIG. 5) formed on the upper surface of the bottom plate 16. One end of the fixing portion 52 in the Y-axis direction is formed continuously from the first upright portion 53, and the other end in the Y-axis direction has the second upright portion 53 fixed thereto.
[0036] The fixing portion 52 further has a first bent portion 521 and a second bent portion 522. The first bent portion 521 is a plate portion parallel to the XZ plane, and is formed by bending the other end of the fixing surface 520 by approximately 90° so as to stand up relative to the bottom plate 16. The second bent portion 522 is formed by bending the upper portion of the first bent portion 521 at a predetermined angle θ1 (see FIG. 8 ), for example, 45° in this embodiment, relative to the XZ plane (first bent portion 521) toward the first standing portion 53 (in the −Y direction).
[0037] The first bent portion 521 is provided with a pair of first screw holes 521A through which screws N4 for fixing to the peripheral wall portion 16A (see FIG. 5) of the bottom plate 16 are inserted. The second bent portion 522 is provided with a pair of screw holes 522A through which screws N2 for fixing to the lower end portion of the second upright portion 54 are inserted, and a fitting hole 522B into which a claw portion 542B (see FIG. 10) described later provided on the second upright portion 54 is fitted. The fitting hole 522B is an oval or rectangular through-hole that passes through the second bent portion 522 and is provided in approximately the center of the second bent portion 522. The pair of screw holes 522A are provided on both sides of the second bent portion in the X-axis direction so as to sandwich the fitting hole 522B.
[0038] (1st standing part) The first upright portion 53 is a plate portion parallel to the XZ plane that stands upright relative to the bottom plate 16, with its upper end continuing with one end of the placement portion 51 and its lower end continuing with one end of the fixing portion 52. Rib portions 53R are formed on both edges of the first upright portion 53 in the X-axis direction by bending them at approximately 90° toward the second upright portion 54 in the Y-axis direction, thereby increasing the strength of the first upright portion 53.
[0039] (2nd standing part) The second upright portion 54 is a plate portion that stands upright relative to the bottom plate 16. The second upright portion 54 is connected at its upper end to the other end (assembly surface 511) of the mounting portion 51 and at its lower end to the other end (second bent portion 522) of the fixing portion 52 so as to face the first upright portion 53 in the Y-axis direction, thereby forming the mounting base 50.
[0040] As shown in FIG. 9 , the second upright portion 54 has a first portion 541 and a second portion 542. The first portion 541 forms the upper portion of the second upright portion 54, and the second portion 542 forms the lower portion of the second upright portion 54. The first portion 541 is a plate portion parallel to the XZ plane, and the second portion 542 is inclined at a predetermined angle θ2 (see FIG. 9 ) with respect to the XZ plane (first portion 541) toward the opposite side (+Y direction) from the first upright portion 53. The predetermined angle θ2 is set to be the same as the predetermined angle θ1 (45° in this embodiment), which is the inclination angle of the second bent portion 522 of the fixing portion 52. As a result, when the second upright portion 54 is attached to the mounting base main body 50A, the second portion 542 of the second upright portion 54 is superimposed on the second bent portion 522 of the fixing portion 52 in parallel with the second bent portion 522.
[0041] The first portion 541 is provided at both corners in the X-axis direction at its upper end with a pair of screw holes 541A through which screws N1 are inserted for fastening to the mounting surface 511 of the mounting portion 51. In addition, a notch 541B is provided at the upper end of the first portion 541 between the pair of screw holes 541A to expose the second screw hole 511B of the mounting surface 511 of the mounting portion 51 to the outside.
[0042] The second portion 542 is provided with a pair of screw holes 542A through which screws N2 for fixing the second bent portion 522 of the fixed portion 52 are inserted, and with claw portions 542B that fit into fitting holes 522B provided in the second bent portion 522. The claw portions 542B are formed by cutting and raising the approximate center of the second portion toward the fixed portion 52 at an angle of approximately 90°.
[0043] In addition, rib portions 541R are formed by bending the edges on both sides of the first portion 541 in the X-axis direction by approximately 90 degrees in the Y-axis direction toward the opposite side from the first standing portion 53, and rib portions 542R are formed by bending the edges on both sides of the second portion 542 in the X-axis direction by approximately 90 degrees toward the opposite side from the first standing portion 53. This increases the strength of the second standing portion 54.
[0044] [Function of the accumulator mounting base] The mounting base 50 of this embodiment configured as described above is used with the second upright portion 54 assembled to the frame main body 50A. When assembling the second upright portion 54 to the frame main body 50A, the first portion 541 of the second upright portion 54 is overlapped on the assembly surface 511 of the mounting portion 51, and the second portion 542 of the second upright portion 54 is overlapped on the second bent portion 522 of the fixing portion 52, thereby assembling the second upright portion 54 to the frame main body 50A.
[0045] At this time, the pair of first protrusions 512 provided on the assembly surface 511 facilitates the alignment of the first portion 541 of the second upright portion 54 with respect to the mounting surface 511, and also enables the alignment of the second portion 542 of the second upright portion 54 with respect to the second bent portion 522 of the fixing portion 52. Furthermore, the claws 542B provided on the second portion 542 fit into the fitting holes 522B of the second bent portion 522, preventing the second upright portion 54 from sliding down the second bent portion 522. This enables the second upright portion 54 to be temporarily fixed to the mounting base main body 50A, and facilitates the subsequent permanent fixation of the second upright portion 54 to the mounting base main body 50A with the screws N1 and N2.
[0046] (Installation of accumulator) When installing the accumulator 7 on the bottom plate 16, first, the mounting base 50 is assembled to the bottom plate 16 of the housing 10. Specifically, the mounting base 50 is positioned on the bottom plate 16 by engaging the opening 520A formed in the fixing surface 522 of the mounting base 50 with the positioning protrusion 16B formed on the upper surface of the bottom plate 16, and then the peripheral wall portion 16A of the bottom plate 16 and the first bent portion 521 of the fixing portion 52 are fixed using two screws N4 (see FIG. 5). This fixes the mounting base 50 to the bottom plate 16.
[0047] Note that when the mount 50 is fixed to the bottom plate 16, the mount 50 may be fixed with the second upright portion 54 assembled to the mount main body 50A, or the mount main body 50A may be fixed to the bottom plate 16 and then the second upright portion 54 may be assembled to the mount main body 50. According to this embodiment, the second portion 542 of the second upright portion 54 is formed as an inclined surface inclined at a predetermined angle rather than a vertical surface. If the second portion 542 is formed parallel to the XY plane, the outer casing of the accumulator 7 placed on the mount 50 will interfere with the tool, making it difficult to tighten the screw N2. Furthermore, if the second portion 542 is formed parallel to the XZ plane, the peripheral wall portion 16A of the bottom plate 16 will interfere with the tool, making it difficult to tighten the screw N2. Since the second portion 542 is formed as an inclined surface inclined at a predetermined angle as in this embodiment, the accumulator 7 and the peripheral wall portion 16A do not get in the way of the tool, and therefore the screw N2 is more easily accessible to the tool, facilitating the work of tightening the screw N2 into the screw hole 542A. Therefore, the workability of assembling the second upright portion 53 to the fixed portion 52 can be improved.
[0048] After the mounting base 50 is installed on the bottom plate 50, the accumulator 7 is fixed to the mounting portion 51 of the mounting base 50. When fixing the accumulator 7 to the mounting portion 51, a pair of legs 70B of the foot stand 70 fixed to the bottom of the accumulator 7 are fitted into a pair of open grooves 510B of the mounting surface 510 (see FIG. 6). At this time, the second protrusion 513 provided on the mounting portion 51 functions to position and guide the foot stand 70 relative to the mounting surface 510. After the foot stand 70 is placed on the mounting surface 510, the fixing piece 70A of the foot stand 70 is fixed to the assembly surface 511 of the mounting portion 51 with the screw N3.
[0049] In this way, the accumulator 7 is fixed to the mounting base 50. In the mounting base 50 of this embodiment, one end of the placing portion 51 in the Y-axis direction and one end of the fixing portion 52 in the Y-axis direction are integrated by the first upright portion 53, and the other end of the placing portion 51 in the Y-axis direction and the other end of the fixing portion 52 in the Y-axis direction are connected by the second upright portion 54. Therefore, even if the mounting base 50 is subjected to an impact due to the weight of the accumulator 7, vibrations during transportation of the outdoor unit 100, or an unintentional drop of the outdoor unit 100, the mounting base 50 has increased strength against deformation.
[0050] In other words, according to this embodiment, since the mounting base 50 is provided with the second upright portion 54, when the accumulator 50 is subjected to an impact such as its own weight or vibration, downward deformation of the other end of the mounting portion 51, which would occur if the second upright portion 54 were not present, can be suppressed. This allows the posture of the accumulator 7 to be maintained stably, and prevents deformation or damage to the refrigerant piping connected to the accumulator 7 due to vibration of the accumulator 7.
[0051] (Installation of outdoor unit) When installing the outdoor unit 100, as described above, an indoor unit (not shown) is connected via refrigerant pipes L1, L2 to the first connection valve 31 and the second connection valve 32 in the machine room 2. At this time, the machine room front panel 13 and the lower rear panel 14b of the housing 10 are removed to expose the first connection valve 31, the second connection valve 32 and the mounting base 50 to the outside, and then the refrigerant pipes L1, L2 are connected to the first connection valve 31 and the second connection valve 32.
[0052] 11 is a perspective view of the main parts of the outdoor unit 100, showing the state when the machine room front panel 13 and the lower rear panel 14b are removed. When the lower rear panel 14b is removed as shown in the figure, the mounting base 50 can be exposed to the outside through the service opening 14c formed between the upper rear panel 14a and the bottom plate 16.
[0053] The service opening 14c corresponds to the "opening" of the present invention that exposes the second upright portion 54 of the mounting base 50 to the outside, and the side surface of the housing 10 on which the service opening 14c is formed corresponds to the "side surface" of the present invention that has the service opening 14c and is positioned opposite the second upright portion 54 of the mounting base 50. The lower rear panel 14b corresponds to the "lid" of the present invention that is detachably attached to the side surface and closes the service opening 14c.
[0054] When the refrigerant pipe L1 connected to the first connection valve 31 and the refrigerant pipe L2 connected to the second connection valve 32 are drawn out to the rear side, the refrigerant pipes L1, L2 are drawn out to the outside of the outdoor unit 100 through the hollow portion 50s of the mounting base 50 and through insertion holes 141, 142 (see FIG. 2) provided in the lower rear panel 14b, as shown in FIG. 4. When the refrigerant pipes L1, L2 are passed through the hollow portion 50s of the mounting base 50, the second upright portion 54 is removed from the mounting base main body 50A.
[0055] Furthermore, during maintenance work on the outdoor unit 100 or when relocating the outdoor unit 100, the second upright portion 54 can be removed from the mount body 50A to open the hollow portion 50s of the mount 50, making it easy to remove and insert the refrigerant pipes L1, L2 from and into the hollow portion 50s. In particular, in this embodiment, as shown in FIG. 4 , the refrigerant pipes L1, L2 connected to the first connection portion 31 and the second connection portion 32 are bent approximately 90 degrees and pulled out below the accumulator 7, making it very difficult to remove and insert the refrigerant pipes L1, L2 from and into the hollow portion 50s without opening the hollow portion 50s. According to this embodiment, even when the refrigerant pipes L1, L2 are connected to the connection valves, it is easy to arrange the refrigerant pipes L1, L2 in the hollow portion 50s of the mount 50.
[0056] Furthermore, by arranging the refrigerant pipes L1 and L2 in the hollow portion 50s of the mounting base 50, the limited space within the machine room 2 can be effectively utilized. If the accumulator 7 is directly fixed to the bottom plate 16 without using the mounting base 50 of the present invention, the accumulator 7 would get in the way when drawing the refrigerant pipes L1 and L2 to the rear side, as described above. Therefore, it becomes necessary to arrange the accumulator 7 on the rear side of the compressor 6 or to arrange the refrigerant pipes L1 and L2 next to the accumulator 7 (on both sides of the accumulator 7 in the Y-axis direction). If the accumulator 7 is arranged on the rear side of the compressor 6, the dimensions of the casing 10 will be larger in the X-axis direction compared to when the accumulator 7 is arranged diagonally behind the compressor 6 as in this embodiment. Furthermore, if the refrigerant pipes L1 and L2 are arranged next to the accumulator 7, the dimensions of the casing 10 will be larger in the Y-axis direction. Thus, if the accumulator 7 is directly fixed to the bottom plate 16, the dimensions of the casing 10 will have to be larger in order to draw the refrigerant pipes L1 and L2 to the rear side. In contrast, in the present invention, the accumulator 7 is raised from the bottom plate 16 by the mounting base 50, and the refrigerant pipes L1, L2 are arranged in the hollow portion 50s of the mounting base 50, thereby making it possible to pull out the refrigerant pipes L1, L2 to the rear side while preventing the housing 10 from becoming larger, as would be the case if the accumulator 7 were fixed to the bottom plate 16.
[0057] In the mounting base 50 of this embodiment, the second portion 542 of the second upright portion 54 is not vertical but is inclined at a predetermined angle toward the outside and above the service opening 14c, which improves tool accessibility to the screw N2 that secures the second portion 542 to the fixed portion 52, facilitating loosening of the screw N2. Similarly, when attaching the second upright portion 54, the screw N2 can be easily tightened, which improves the ease of attaching and detaching the second upright portion 54.
[0058] After the refrigerant pipes L1 and L2 have been connected, the second upright portion 54 is reassembled to the mounting base body 50A, and the installation of the outdoor unit 100 is completed by attaching the machine room front panel 13 and closing the service opening 14c with the lower rear panel 13b.
[0059] As described above, according to this embodiment, the second upright portion 54 of the mounting base 50 is configured to be detachable from the mounting base main body 50A, and therefore the second upright portion 54 can function as a reinforcing portion of the mounting base 50 when transporting or operating the outdoor unit 100. On the other hand, when connecting the refrigerant pipes L1, L2 when installing the outdoor unit 100 or when performing maintenance on the outdoor unit 100, the second upright portion 54 can be removed from the mounting base main body 50 to easily position the refrigerant pipes L1, L2 in the hollow portion 50s of the mounting base 50, improving workability and enabling effective use of the limited space in the machine room 2.
[0060] Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to the above-described embodiments and that various modifications can be made.
[0061] For example, in the above embodiment, the second upright portion 54 of the mounting base 50 has a three-dimensional shape having a first portion 541 and a second portion 542, but this is not limited to this, and the second upright portion 54 may be formed in a flat plate shape similar to the first upright portion 53.
