Description

Technical Field

[0001] The present invention relates to an outdoor unit of an air conditioner.

Background Art

[0002] An air conditioner generally includes an indoor unit installed indoors and an outdoor unit installed outdoors, and a refrigerant circuit formed by connecting these indoor and outdoor units with refrigerant pipes. The refrigerant circulates through the refrigerant circuit to adjust the indoor temperature and humidity.

[0003] A compressor that is connected to the refrigerant circuit and circulates the refrigerant is housed in the housing of the outdoor unit. A fixing base is provided at the lower part of the compressor, and the compressor is fixed to the bottom plate of the housing by connecting the fixing base to the bottom plate of the housing with a fastening member via an elastic member. At this time, the elastic member undergoes elastic deformation (hereinafter sometimes referred to as the initial deformation amount) corresponding to the tightening force of the fastening member. Then, the elastic member that is elastically deformed with the initial deformation amount undergoes elastic deformation (hereinafter sometimes referred to as the load deformation amount) corresponding to the vibration generated during the driving of the compressor. By this, the vibration generated during the driving of the compressor is absorbed by the elastic member, so that the transmission of the vibration during the driving of the compressor to the outside is reduced.

[0004] Here, in order to cope with both the vibration during the transportation of the outdoor unit and the vibration during the driving of the compressor, only during the transportation of the outdoor unit, a spacer made of a material harder than the elastic member is mounted between the fixing base and the elastic member or between the bottom plate of the housing and the elastic member to compress the elastic member, thereby increasing the initial deformation amount and reducing the load deformation amount due to the vibration during transportation, so as to prevent the piping components connected to the compressor from being damaged by the vibration during the transportation of the outdoor unit. A technique has been proposed (for example, Patent Document which describes the spacer as a hook).

Patent Document 1

[0006] However, the spacer used in Patent Document 1 is only held in place by the bottom plate of the housing and an elastic member, and may fall out due to vibrations during transportation of the outdoor unit. If the spacer falls out during transport of the outdoor unit, it will not be possible to reduce the amount of deformation under load during transport, and the vibrations during transport may cause the elastic material to deform significantly, potentially damaging the refrigerant piping connected to the compressor.

[0007] Therefore, the present invention was made to solve these problems, and aims to provide an outdoor unit for an air conditioner that prevents spacers from falling out due to vibration during transportation, reduces vibration of the compressor during transportation, and prevents damage to refrigerant piping and other components connected to the compressor. [Means for solving the problem]

[0008] To achieve the above objective, an outdoor unit of an air conditioner according to one aspect of the present invention comprises a compressor and a housing for the compressor, wherein a fixing part provided at the bottom of the compressor is fixed to the bottom plate of the housing via an elastic member, and the outdoor unit of an air conditioner comprises a spacer detachably disposed above or below the elastic member for compressing the elastic member, and the spacer has a first restricting part that contacts a part of the housing to prevent it from falling off due to vibration during transport. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide an outdoor unit for an air conditioner that reduces vibration of the compressor during transportation, preventing damage to refrigerant piping and other components connected to the compressor. [Brief explanation of the drawing]

[0011] Next, embodiments of the present invention will be described with reference to the drawings. The embodiments shown below illustrate devices and methods for realizing the technical idea of ​​the present invention, and the technical idea of ​​the present invention is not limited to the materials, shapes, structures, arrangements, etc. of the components described below. Various modifications can be made to the technical idea of ​​the present invention within the technical scope defined by the claims described in the patent claims.

[0012] Figure 1 is a refrigerant circuit diagram of an air conditioner 1 according to one embodiment of the present invention. The air conditioner 1 of this embodiment consists of an indoor unit 2 and an outdoor unit 3. The indoor unit 2 is equipped with an indoor heat exchanger 4 that performs heat exchange between the refrigerant and the indoor air. Although only the indoor heat exchanger 4 is shown for the indoor unit 2, the indoor unit 2 is usually equipped with other components such as an indoor fan that blows the heat-exchanged air into the room and a control device that controls the indoor unit 2.

[0013] The outdoor unit 3 is equipped with a compressor 6, a heat exchanger unit 7, and an expansion valve 8, which are sequentially connected by refrigerant piping. In addition to the equipment described above, the outdoor unit 3 is also connected to various valve mechanisms such as four-way valves and accumulators, but these are omitted in Figure 1. The outdoor unit 3 and the indoor unit 2 are connected by refrigerant piping, and a refrigerant circuit 9 is formed in which the refrigerant circulates between the outdoor unit 3 and the indoor unit 2 when driven by the compressor 6.

[0014] Next, Figure 2 shows a perspective view of the outdoor unit 3 of the air conditioner 1, which is an upward-blowing outdoor unit. In the drawings from Figure 2 onward, the configuration of each component will be explained by specifying the directions of up, down, front, back, left, and right, as indicated by the arrows in Figure 2. The outdoor unit 3 has a large casing 10. When the outdoor unit 3 is installed on a horizontal surface, if we define the vertical direction (up and down) as vertical and the horizontal direction (left and right) perpendicular to the vertical as horizontal, the casing 10 is formed such that the vertical length is longer than the horizontal width in terms of its aspect ratio.

[0015] An air intake port 11 for drawing air into the interior of the housing 10 is provided on the right side of the housing 10. Although not shown in Figure 2, air intake ports are also provided on the left side and rear side of the housing 10. Inside the housing 10, a heat exchanger unit 7 is arranged along the air intake port 11. The heat exchanger unit 7 is formed by stacking two heat exchangers, each shaped like a U when viewed from above, in an upper and lower tier. The configuration of the heat exchanger unit 7 is arbitrary, and its shape and configuration can be arbitrarily selected according to the specifications. A fan 12 is located at the top of the housing 10, and an air outlet port 13 is formed above this fan 12.

[0016] The service panel 14 is screwed to the housing 10, covering the upper part of the front side of the housing 10. This service panel 14 is a removable panel for performing maintenance on equipment and other items housed inside the housing 10, and an electrical component box (not shown) containing various electrical components is housed inside the service panel 14. In Figure 2, the service panel covering the lower part of the front side of the housing 10 has been removed, and the compressor housing box 15 housing the compressor 6, the expansion valve 8, refrigerant piping, etc., are arranged in the lower part of the housing 10. Here, the compressor housing box 15 corresponds to the housing box of the present invention.

[0017] Figure 3 shows the internal structure of the compressor storage box 15 when transporting the outdoor unit 3, and is a view of the compressor 6 from above. The compressor storage box 15 includes a front panel 15a, a left side panel 15b, a right side panel 15c, a back panel 15d, and a ceiling plate (not shown) that closes the upper opening of the rectangular parallelepiped formed by these plates. The front panel 15a is detachably arranged with respect to the left side panel 15b, the right side panel 15c, and the ceiling plate, and is fixed by screwing.

[0018] A fixing base 16 is integrally provided at the lower part of the cylindrical compressor 6. The fixing base 16 includes a fixing main body part 17 joined to the bottom of the compressor 6, and four first fixing parts 18a to 18d extending horizontally outward at intervals of approximately 90° in the circumferential direction from the fixing main body part 17. The first fixing part 18a located on the left front side of the fixing base 16 is fixed to the bottom plate 23 by the first fastening part 19, and the second fixing part 18b located on the right side of the fixing base 16 is fixed to the bottom plate 23 by the second fastening part 20. Further, the third fixing part 18c located on the right rear side of the fixing base 16 is fixed to the bottom plate 23 by the third fastening part 21, and the fourth fixing part 18d located on the left rear side of the fixing base 16 is fixed to the bottom plate 23 by the fourth fastening part 22.

[0019] FIG. 4 shows the constituent members of the first fastening part 19 to the fourth fastening part 22. Bolt insertion holes 24 penetrating in the vertical direction are formed in the first fixing part 18a to the fourth fixing part 18d of the fixing base 16, and four bolt insertion holes (not shown) penetrating in the vertical direction are also formed in the bottom plate 23 of the housing 10 at positions where the first fixing part 18a to the fourth fixing part 18d are fixed. Here, the first fixing part 18a to the fourth fixing part 18d correspond to the fixing parts of the present invention. The first fastening part 19 is composed of a hollow cylindrical first elastic member 25, an annular second elastic member 26, detachable first spacers 27 and second spacers 28, and a fastening bolt 29. The fastening bolt 29 has a screw part 29b formed at the tip, and this screw part 29b is fastened to a nut (not shown) disposed on the back surface of the first fixing part 18a. Here, the first elastic member 25 and the second elastic member 26 correspond to the elastic members of the present invention, and the fastening bolt corresponds to the fastening member of the present invention.

[0020] The first elastic member 25 is a rubber component such as ethylene propylene rubber, and is positioned between the lower part of the first fixing part 18a and the upper surface of the bottom plate 23, with its own shaft hole aligned with the bolt insertion hole 24 of the first fixing part 18a and the bolt insertion hole of the bottom plate 23. The second elastic member 26 is also a rubber component such as ethylene propylene rubber, and is positioned between the upper part of the first fixing part 18a and the first spacer 27. The first elastic member 25 and the second elastic member 26 are elastically deformed to an initial deformation amount by tightening the fastening bolts 29 described later, thereby dampening vibrations generated when the compressor 6 is driven, preventing damage to refrigerant piping connected to the compressor 6 due to vibration, and preventing the generation of noise due to resonance of the housing 10. The physical properties such as elastic modulus and shape of these members have been determined accordingly.

[0021] The first spacer 27 is made of a metal plate and comprises a main body 27b with a notch 27a through which a fastening bolt 29 can be inserted, a first restricting portion 27c formed by bending at a right angle the edge of the main body 27b opposite to the edge with the notch 27a (the front edge in Figure 4), and a second restricting portion 27d formed by bending at a right angle the right edge of the notch 27a. Here, the first spacer 27 corresponds to the first spacer of the present invention, and the notch 27a corresponds to the first notch of the present invention. The second spacer 28 is a rectangular metal plate with a notch 28a through which a fastening bolt 29 can be inserted. The fastening bolt 29 is a bolt with a washer 29a. Here, the second spacer 28 corresponds to the second spacer of the present invention, the notch 28a corresponds to the second notch of the present invention, and the peripheral edge 28b of the second spacer 28 opposite to the edge where the opening of the notch 28a is provided corresponds to the restricted surface of the present invention.

[0022] The first fastening portion 19, the first fixing portion 18a, and the bottom plate 23 are fixed in the following procedure. First, the second elastic member 26 is placed on top of the first fixing portion 18a. Next, the first spacer 27 is placed on top of the second elastic member 26 with the first restricting portion 27c facing forward and the second restricting portion 27d facing right, as shown in Figure 5, and the notch 27a aligned with the axial hole of the second elastic member 26. Next, the second spacer 28 is placed on top of the first spacer 27 with the opening of the notch 28a facing left, the peripheral edge 28b opposite to the edge where the opening of the notch 28a of the second spacer 28 is provided in contact with the second restricting portion 27d of the first spacer 27, and the notch 28a intersects with the notch 17a, as shown in Figure 5. Next, the shaft of the fastening bolt 29 is inserted through the notch 28a of the second spacer 28, the notch 27a of the first spacer 27, and the second elastic member 26. Then, the shaft of the fastening bolt 29 is inserted through the bolt insertion hole 24 of the first fixing part 18a, the shaft hole of the first elastic member 25, and the insertion hole of the bottom plate 23, and a nut (not shown) is engaged with the threaded portion 29b at the tip of the fastening bolt 29 shaft that protrudes from the back surface of the bottom plate 23. At this time, the first elastic member 25 and the second elastic member 26 elastically deform to the initial deformation amount when the first spacer 27 and the second spacer 28 are inserted due to the tightening of the fastening bolt 29.

[0023] The second fastening portion 20 is composed of a first elastic member 25, a second elastic member 26, a detachable first spacer 27 and a third spacer 30, and a fastening bolt 29. The third spacer 30 is formed at one end in the longitudinal direction of the spacer connecting member 31, which is made of a metal plate extending in a straight line. A fourth spacer 32, which will be described later, is formed at the other end in the longitudinal direction of the spacer connecting member 31. The third spacer 30, formed at one end of the spacer connecting member 31 in the longitudinal direction, is formed as a disc shape that bulges out larger than the width dimension of the spacer connecting member 31, and has a notch 30a formed in a direction perpendicular to the longitudinal direction of the spacer connecting member 31 through which a fastening bolt 29 can be inserted. The notch 30a is open on the left side in Figure 4. Here, the third spacer 30 corresponds to the second spacer of the present invention, and the notch 30a corresponds to the second notch of the present invention.

[0024] The second fastening portion 20, the second fixing portion 18b, and the bottom plate 23 are fixed in the following procedure. First, the second elastic member 26 is placed on top of the second fixing portion 18b. Next, the first spacer 27 is placed on top of the second elastic member 26 with the first restricting portion 27c facing forward, the second restricting portion 27d facing right, and the notch 27a aligned with the axial hole of the second elastic member 26, as shown in Figure 5. Next, the third spacer 30, formed at one end in the longitudinal direction of the spacer connecting member 31, is placed on top of the first spacer 27 with the opening of the notch 30a facing left, the periphery of the third spacer 30 in contact with the second restricting portion 27d of the first spacer 27, and the notch 30a intersecting the notch 27a. Next, the shaft of the fastening bolt 29 is inserted through the notch 30a of the third spacer 30, the notch 27a of the first spacer 27, and the axial hole of the second elastic member 26. Then, the shaft of the fastening bolt 29 is inserted through the bolt insertion hole 24 of the first fixing part 18a, the axial hole of the first elastic member 25, and the insertion hole of the bottom plate 23, and a nut (not shown) is engaged with the threaded portion of the tip of the fastening bolt 29 shaft that protrudes from the back surface of the bottom plate 23. At this time, the first elastic member 25 and the second elastic member 26 elastically deform to the initial deformation amount when the first spacer 27 and the third spacer 30 are inserted due to the tightening of the fastening bolt 29.

[0025] The third fastening portion 21 is composed of a first elastic member 25, a second elastic member 26, detachable fourth spacers 32 and fifth spacers 33, and a fastening bolt 29. The fourth spacer 32, formed at the other end of the spacer connecting member 31 in the longitudinal direction, is formed as a disc shape that bulges out larger than the width dimension of the spacer connecting member 31, and has a notch 32a formed in the direction along the longitudinal direction of the spacer connecting member 31. The notch 32a opens to the rear side in Figure 4. Here, the fourth spacer 32 corresponds to the second spacer of the present invention, and the notch 32a corresponds to the second notch of the present invention.

[0026] The fifth spacer 33 is composed of a fixing piece 33a that extends linearly with the same width as the spacer connecting member 31, a disc portion 33b that bulges out larger than the width dimension of the spacer connecting member 31 at one end of the fixing piece 33a, a notch 33c formed in the disc portion 33b, and a plate-shaped spacer restricting portion 33d formed by bending a part of the edge of the disc portion 33b opposite to the edge where the notch 33c is provided at a right angle. The fifth spacer 33 is integrally fixed to the spacer connecting member 31 by screwing a connecting screw 34a that passes through the spacer connecting member 31 into a screw hole 34b formed in the fixing piece 33a, with the fixing piece 33a in contact with the back surface of the spacer connecting member 31 and the notch 33c aligned with the notch 32a. Here, the fifth spacer 33 corresponds to the first spacer of the present invention, and the notch 33c corresponds to the first notch of the present invention.

[0027] The third fastening portion 21, the third fixing portion 18c, and the bottom plate 23 are fixed in the following procedure. First, the second elastic member 26 is placed on top of the third fixing portion 18c. Next, the fifth spacer 33, which is fixed to the fourth spacer 32 formed at the other end of the longitudinal direction of the spacer connecting member 31 by screwing in the connecting screw 34a, is placed on top of the second elastic member 26 together with the fourth spacer 32. At this time, the notch 33c of the fifth spacer 33 and the notch 32a of the fourth spacer 32 are aligned with the axial hole of the second elastic member 26. Next, the shaft of the fastening bolt 29 is inserted through the notch 33c of the fifth spacer 33, the notch 32a of the fourth spacer 32, and the axial hole of the second elastic member 26. Then, the shaft of the fastening bolt 29 is inserted through the bolt insertion hole 24 of the third fixing part 18c, the shaft hole of the first elastic member 25, and the insertion hole of the bottom plate 23, and a nut (not shown) is engaged with the threaded portion of the tip of the fastening bolt 29 shaft that protrudes from the back surface of the bottom plate 23. At this time, the first elastic member 25 and the second elastic member 26 are elastically deformed by the tightening of the fastening bolt 29 to the initial deformation amount when the first spacer 27 and the fourth spacer 32 are inserted.

[0028] The fourth fastening section 22, although not shown in Figure 4, is composed of a first elastic member 25, a second elastic member 26, and a fastening bolt 29. Unlike the other fastening sections, the fourth fastening section 22 does not use a spacer. The fourth fastening portion 22, the fourth fixing portion 18d, and the bottom plate 23 are fixed in the following procedure. First, the second elastic member 26 is placed on the upper part of the fourth fixing portion 18d. Then, the first elastic member 25 is placed between the fourth fixing portion 18d and the fourth fastening portion 22 with its shaft hole aligned with the bolt insertion hole 24 of the fourth fixing portion 18d. The shaft of the fastening bolt 29 is inserted through the bolt insertion hole 24 of the fourth fixing portion 18d and the shaft hole of the first elastic member 25, and a nut (not shown) is engaged with the threaded portion at the tip of the shaft of the fastening bolt 29 protruding from the back surface of the bottom plate 23. At this time, the first elastic member 25 and the second elastic member 26 are elastically deformed by the tightening of the fastening bolt 29.

[0029] After fixing the compressor 6 to the bottom plate 23 of the housing 10 as described above, the front plate 15a of the compressor housing box 15 is attached to the left side plate 15b, the right side plate 15c, and the top plate with screws. As a result, as shown in Figure 3, the first restricting portion 27c of the first spacer 27 of the first fastening portion 19 and the second fastening portion 20 comes into contact with the inner wall of the front plate 15a.

[0030] The first spacer 27 of the first fastening portion 19 and the second fastening portion 20 has a notch 27a that opens at the rear and extends in the front-rear direction, so that even if the first spacer 27 tries to move forward due to vibrations during transport, the front plate 15a prevents the first spacer 27 from moving. The second spacer 28 of the first fastening portion 19 has a notch 28a that opens on the left side and extends to the right. Even if the second spacer 28 tries to move to the right due to vibrations during transportation, the second restricting portion 27d of the first spacer 27 prevents the second spacer 28 from moving.

[0031] The third spacer 30 of the second fastening portion 20 has a notch 30a that opens to the left and extends to the right. Even if the third spacer 30 tries to move to the right due to vibrations during transportation, the second restricting portion 27d of the first spacer 27 prevents the movement of the third spacer 30. The fourth spacer 32 and fifth spacer 33 of the third fastening portion 21 have notches 32a and 33c that open at the rear and extend forward, so that even if the fourth spacer 32 and fifth spacer 33 try to move forward due to vibrations during transport, the third spacer 30 prevents the fourth spacer 32 and fifth spacer 33 from moving forward via the spacer connecting member 31.

[0032] Therefore, even if vibrations during the transport of the outdoor unit 3 act on the first fastening part 19, the second fastening part 20, and the third fastening part 21, it is possible to reliably prevent the first spacer 27 and the second spacer 28 from falling out of the first fastening part 19, the first spacer 27 and the third spacer 30 from falling out of the second fastening part 20, and the fourth spacer 32 and the fifth spacer 33 from falling out of the third fastening part 21.

[0033] Furthermore, by preventing the first spacer 27 to the fifth spacer 33 from falling out, the first elastic member 25 and the second elastic member 26, respectively, positioned between the first fastening part 19 and the third fastening part 21, are maintained in an elastically deformed state by the initial deformation amount due to the tightening of the fastening bolts 29. Therefore, even if vibrations during the transport of the outdoor unit 3 are transmitted to the first fixing part 18a to the third fixing part 18c, the load deformation amount of the first elastic member 25 and the second elastic member 26 will be smaller than when the first spacer 27 to the fifth spacer 33 are not inserted, thereby reducing the vibration of the compressor 6 caused by vibrations during the transport of the outdoor unit 3. This prevents damage to refrigerant piping and other components connected to the compressor 6 due to vibrations during transport. Note that the initial deformation amount of each spacer of the first elastic member 25 and the second elastic member 26 when the fastening bolts 29 are tightened can be appropriately changed according to the vibrations expected during the transport of the outdoor unit 3. For example, the initial deformation amount can be easily changed by changing the length of the threaded portion 29b without changing the length of the fastening bolt 29.

[0034] Furthermore, by using two types of spacers, the first spacer 27 and the second spacer 28, to be inserted into the first fastening portion 19, the initial deformation amounts of the first elastic member 25 and the second elastic member 26 can be set to various values ​​compared to using only one type of spacer. For example, by providing three different thicknesses for the first spacer 27 and the second spacer 28, 3 x 3 = 9 different thicknesses can be achieved, allowing for thicknesses that would be difficult to achieve with only one type of spacer. Similarly, by using different thicknesses for the first spacer 27 and the third spacer 30 used in the second fastening portion 20, and the fourth spacer 32 and the fifth spacer 33 used in the third fastening portion 21, the initial deformation amounts of the first elastic member 25 and the second elastic member 26 can be set to various values. This makes it easy to adjust the initial deformation amount to correspond to the vibrations during transportation of the outdoor unit 3, which vary depending on the weight of the compressor and the shape and weight of the outdoor unit's casing, thus preventing damage to piping components connected to the compressor due to vibrations during transportation of the outdoor unit.

[0035] Next, the procedure for removing each spacer from each fastening part after the outdoor unit 3 has been installed will be explained using Figure 6. Figure 6 shows the operation of removing the first spacer 27 and the second spacer 28 from the first fastening part 19, the operation of removing the first spacer 27 and the third spacer 30 from the second fastening part 20, and the operation of removing the fourth spacer 32 and the fifth spacer 33 from the third fastening part 21.

[0036] First, remove the front panel 15a of the compressor housing box 15 from the left side panel 15b, the right side panel 15c, and the top panel. Next, remove the first spacer 27 and the second spacer 28 from the first fastening part 19. At this time, tilt the compressor 6 slightly to the rear to increase the vertical distance between the second spacer 28 and the second elastic member 26. Then, pull out the first restricting part 27c of the first spacer 27 to the front (in the direction of arrow P1) to remove the first spacer 27 from the first fastening part 19. Next, pull out the second spacer 28, from which the restraint of the second restricting part 27d of the first spacer 27 has been released, to the right (in the direction of arrow P3) to remove it from the first fastening part 19. Then, remove the first spacer 27 and the third spacer 30 from the second fastening part 20. In this case, as with the first fastening part 19, the compressor 6 is tilted slightly to the rear to increase the vertical distance between the second spacer 28 and the second elastic member 26. Then, the first restricting part 27c of the first spacer 27 is pulled forward (in the direction of arrow P2) to remove the first spacer 27 from the second fastening part 20. Next, the third spacer 30, whose restraint of the second restricting part 27d of the first spacer 27 has been released, is pulled out of the second fastening part 20 by rotating the spacer connecting member 31 in the direction of arrow P4 with the fourth spacer 32 as the pivot point. Next, the compressor 6 is tilted slightly to the left to increase the vertical distance between the fourth spacer 32 and the second elastic member 26 of the third fastening part 21. Then, the spacer connecting member 31 is pulled forward (in the direction of arrow P5) to remove the fourth spacer 32 and the fifth spacer 33 from the third fastening part 21.

[0037] In this way, by removing the first spacer 27 and the second spacer 28 from the first fastening part 19, the first spacer 27 and the third spacer 30 from the second fastening part 20, and the fourth spacer 32 and the fifth spacer 33 from the third fastening part 21, the first elastic member 25 and the second elastic member 26 of the first fastening part 19 to the third fastening part 21 are released from the compression state caused by each spacer, and the initial deformation amount of the first elastic member 25 and the second elastic member 26 becomes smaller compared to when each spacer is inserted. As a result, the load deformation amount of the first elastic member 25 and the second elastic member 26 due to vibrations when the compressor 6 is driven becomes a value that dampens the vibrations when the compressor 6 is driven, and the transmission of vibrations when the compressor 6 is driven to the outside can be reduced.

[0038] Furthermore, the third fastening portion 21 is located in a confined space inside the housing 10, surrounded by the right side panel 15c, the back panel 15d, etc., making manual work by an operator difficult in this working environment. However, the fourth spacer 32, which is integrally fixed to the fifth spacer 33, is formed at the other end of the spacer connecting member 31, and by simply moving the spacer connecting member 31 forward, the fifth spacer 33 and the fourth spacer 32 can be easily pulled out from the confined space. Furthermore, since the first spacer 27 and the second spacer 28 are arranged overlapping in the first fastening portion 19, the first spacers 27 and 30 are arranged overlapping in the second fastening portion 20, and the fourth spacers 32 and 33 are arranged overlapping in the third fastening portion 21, visibility and workability can be improved when removing spacers, such as when forgetting to remove them.

[0039] It should be noted that the present invention is not limited to the embodiments described above, but rather represents an example of the present invention. In the implementation stage, the components can be modified and materialized without departing from the spirit of the invention, and various changes or improvements can be made to the above embodiments. Furthermore, various inventions can be formed by appropriately combining the multiple components disclosed in the above embodiments. For example, in the above embodiment, the first restricting portion 27c of the first spacer 27 of the first fastening portion 18 and the second fastening portion 20 is brought into contact with the front panel 15a of the compressor storage box 15 on which the outdoor unit 3 is placed, to prevent the first spacer 27 from falling out during transport of the outdoor unit 3. However, in the case of an outdoor unit 3 that does not have a compressor storage box 15, the first restricting portion 27c of the first spacer 27 of the first fastening portion 18 and the second fastening portion 20 may be brought into contact with a part of the housing 10, such as a service panel 14, to prevent the first spacer 27 from falling out during transport of the outdoor unit 3.

[0040] Furthermore, in the above embodiment, the first spacer 27 and the second spacer 28 are arranged on top of the second elastic member 26 of the first fastening portion 19. However, even when the first spacer 27 and the second spacer 28 are arranged on top of the lower part of the second elastic member 26 and the upper part of the first fixing portion 18a, the first elastic member 25 and the second elastic member 26 can be elastically deformed to their initial deformation amount by tightening the fastening bolts 29. Similarly, when the first spacer 27 and the third spacer 39 are arranged on top of the lower part of the second elastic member 26 of the second fastening portion 20 and the upper part of the second fixing portion 18b, or when the fourth spacer 32 and the fifth spacer 33 are arranged on top of the lower part of the second elastic member 26 of the third fastening portion 21 and the upper part of the third fixing portion 18c, the first elastic member 25 and the second elastic member 26 can be elastically deformed to their initial deformation amount by tightening the fastening bolts 29.
