[0004] The present disclosure provides an outdoor unit for an air conditioner that can easily reduce noise without interfering with the attachment of a sticker. [Means for solving the problem]

[0005] The outdoor unit of the air conditioner in the present disclosure comprises an outdoor heat exchanger, a compressor, and a housing that stores the outdoor heat exchanger and the compressor, the housing having an exterior sheet metal part that covers from the side a machine room in which the compressor is located, the exterior sheet metal part having a flat portion formed over substantially the entire exterior sheet metal part in the vertical direction, the flat portion having a seal affixing portion and a bead, and the bead being formed in an area of ​​the flat portion excluding the seal affixing portion. Effect of the Invention

[0008] (The knowledge and other information that formed the basis of this disclosure) At the time when the inventors arrived at the idea of ​​the present disclosure, there was a technique for suppressing noise by using sound-absorbing members in the technical field of refrigeration machines including air conditioners. However, in the above technology, the cost is likely to increase because of the addition of sound-absorbing members, and it is difficult for sound-absorbing members to sufficiently suppress the transmission of noise caused by the vibration of each part of the refrigeration machine to the outside. Under such circumstances, the inventors came up with the idea of ​​increasing the rigidity of the exterior sheet metal parts of the outdoor unit in order to suppress noise caused by the vibration of the compressor in the outdoor unit of the air conditioner, thereby making the natural frequency of the exterior sheet metal parts a value away from the operating frequency of the compressor. Then, the inventors discovered a problem that if beads are provided on the exterior sheet metal parts to realize this idea, the unevenness of the beads makes it difficult to attach a seal to the exterior sheet metal parts, and in order to solve this problem, they came to constitute the subject of the present disclosure. Therefore, the present disclosure provides an outdoor unit for an air conditioner that can easily reduce noise without interfering with the attachment of stickers.

[0009] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or duplicate explanation of substantially the same configuration may be omitted. This is to avoid the following explanation becoming more redundant than necessary and to facilitate understanding by those skilled in the art. It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0010] (Embodiment 1) Hereinafter, the first embodiment will be described with reference to the drawings. [1-1. Configuration] [1-1-1. Overall configuration of outdoor unit] Fig. 1 is a perspective view of an outdoor unit 1 of an air conditioner according to embodiment 1. Fig. 2 is a perspective view showing the internal configuration of the outdoor unit 1. In the figure, the symbol X corresponds to the right direction of the outdoor unit 1, the symbol Y corresponds to the front direction of the outdoor unit 1, and the symbol Z corresponds to the upward direction of the outdoor unit 1.

[0011] The outdoor unit 1 is one of the components of an air conditioner and is mainly installed outdoors. The outdoor unit 1 forms a refrigeration circuit by being connected to an indoor unit (not shown) via refrigerant piping. The air conditioner performs air conditioning by heating or cooling the air in the indoor space using an indoor heat exchanger of the indoor unit installed in the indoor space to be air-conditioned.

[0012] The outdoor unit 1 includes a box-shaped housing 10. As shown in FIG. 1 and FIG. 2, the housing 10 includes a top plate 11 that forms the upper surface of the housing 10, a front panel 13 that forms the front surface of the housing 10, and an outdoor unit board 15 that forms the lower surface of the housing 10. The front panel 13 is formed with an air outlet 13a that opens circularly toward the front and is covered by an air outlet grill. The housing 10 also includes an exterior sheet metal part 50 that forms the left side surface of the housing 10 and a part of the left side of the rear surface. The exterior sheet metal part 50 is a part made of sheet metal and is bent into an L-shape in plan view. As shown in FIG. 2, the right side surface of the outdoor unit 1 and a part of the right side of the rear surface are covered by an outdoor heat exchanger 17 that is L-shaped in plan view.

[0013] As shown in Figures 1 and 2, the outdoor unit 1 is divided into two, a machine room 12 and a blower room 14, by a partition plate 16. The machine room 12 is a space located on the left side of the outdoor unit 1, and is a space separated from the outside by a top plate 11, a partition plate 16, a front panel 13, an outdoor unit board 15, and an exterior sheet metal part 50. The exterior sheet metal part 50 is configured to cover the machine room 12 from the left and rear, i.e., from the sides. The blower room 14 is separated from the outside by the top plate 11, the partition plate 16, the front panel 13, the outdoor unit board 15, and an exterior heat exchanger 17.

[0014] As shown in Fig. 2, devices such as a compressor 30 are provided in the machine room 12. The compressor 30 is, for example, a scroll type compressor. When driven, the compressor 30 compresses a gas refrigerant and discharges it as a high-temperature, high-pressure gas refrigerant, which is circulated through the refrigeration circuit of the air conditioner. This enables the air conditioner to condition the air inside the room. When the compressor 30 is operating, vibrations are generated at a frequency corresponding to the operating frequency of the compressor 30.

[0015] A blower (not shown) that blows air forward is provided in the blower chamber 14. When the blower is driven, outside air flows into the blower chamber 14 through the exterior heat exchanger 17 and flows out forward through the air outlet 13a. This promotes heat exchange between the exterior heat exchanger 17 and the exterior air.

[0016] [1-1-2. Composition of exterior sheet metal parts] Fig. 3 is a perspective view of the exterior sheet metal part 50. As shown in Fig. 3, the exterior sheet metal part 50 has a left side surface portion 51 and a left rear surface portion 53 formed by bending. The left side surface portion 51 is a plate-shaped portion that is approximately perpendicular to the left-right direction, and forms the left side surface of the housing 10. The left side surface portion 51 covers the machine chamber 12 from the left, i.e., the side. The left rear surface portion 53 forms a part of the left side of the rear surface of the housing 10. The left rear surface portion 53 covers the machine chamber 12 from the rear.

[0017] FIG. 4 is a diagram showing the exterior sheet metal part 50 as seen from the left. As shown in FIG. 4, a power supply hole 55 opening toward the left direction is formed in the left side surface part 51. The power supply hole 55 is formed in the front part of the left side surface part 51. The power supply hole 55 is a hole for drawing an internal / external connection wire (not shown) connecting the outdoor unit 1 and the indoor unit into the inside of the machine room 12. The internal / external connection wire is connected to an electrical box (not shown) via a terminal block (not shown) provided in the outdoor unit 1. The internal / external connection wire transmits signals exchanged between the outdoor unit 1 and the indoor unit. In addition, the internal / external connection wire transmits power supplied to the indoor unit via a power cord to the outdoor unit 1.

[0018] A piping hole 57 that opens toward the left is formed in the left side surface portion 51. The piping hole 57 is formed in the front portion of the left side surface portion 51. The piping hole 57 is a hole for connecting a refrigerant piping connected to the indoor unit to a two-way or three-way valve or the like that is provided in the machine room 12 and connected to the compressor 30, the outdoor heat exchanger 17, etc.

[0019] In addition, a cover mounting step 51a is formed in the front of the left side surface portion 51 at a position surrounding the power supply hole portion 55 and the piping hole portion 57 from the front, above, and rear. The cover mounting step 51a is a step recessed toward the right side, i.e., toward the inside of the machine room 12. The cover mounting step 51a is recessed on the inside when viewed from the left. The cover mounting step 51a is substantially rectangular when viewed from the left. The cover mounting step 51a is a step for fitting the piping cover 19 (see FIG. 1). During normal use of the air conditioner, the piping cover 19 is fixed to the left side surface portion 51 by screws while being fitted into the cover mounting step 51a, and covers and conceals the power supply hole portion 55 and the piping hole portion 57 from the left.

[0020] As described above, in the exterior sheet metal part 50, the piping cover 19, the power supply hole 55, and the piping hole 57 are concentrated in the front part of the left side surface part 51. Meanwhile, in the rear part of the left side surface part 51, there is a large flat area where no structure such as a large open hole is formed.

[0021] That is, at the rear of the left side surface portion 51, a flat portion 52 is formed as a region that is formed generally flat over substantially the entire left side surface portion 51 in the up-down direction. In this embodiment, the flat portion 52 is a generally rectangular region. In detail, the flat portion 52 is formed over a range in the front-rear direction, i.e., in the width direction of the flat portion 52, from the rear end of the cover mounting step 51a to the curved portion (i.e., the portion of the bend R) between the left side surface portion 51 and the left rear surface portion 53. Also, the flat portion 52 is formed over a range in the up-down direction, from the upper end of the lower hole portion 59 to the curved portion (i.e., the corner R) of the top plate mounting step 54.

[0022] The lower hole 59 is a hole (notch) formed in the lower end of the left side surface portion 51. The top plate mounting step 54 is formed over substantially the entire edge of the upper ends of the left side surface portion 51 and the left rear surface portion 53, and is a step recessed toward the inside of the machine room 12. The edge of the top plate 11 is bent downward, and an insertion portion 54a of the exterior sheet metal part 50 located above the top plate mounting step 54 is inserted into the inside of the edge of the top plate 11. Furthermore, the insertion portion 54a and the edge of the top plate 11 are fastened together with a screw or the like, thereby fixing the top plate 11 and the exterior sheet metal part 50.

[0023] As shown in FIG. 3 and FIG. 4, a central bead 61, a lower bead 63, and an upper bead 65 are formed on the flat surface portion 52. In this embodiment, a total of eight beads 61, 63, and 65 are formed. In this embodiment, each of the beads 61, 63, and 65 is formed in a straight line extending in the width direction of the flat surface portion 52, and protrudes to the left, that is, toward the outside of the machine room 12. In this embodiment, each of the beads 61, 63, and 65 has the same shape. Each of the beads 61, 63, and 65 is formed over substantially the entire flat surface portion 52 in the width direction of the flat surface portion 52. In this embodiment, each of the beads 61, 63, and 65 is formed to be arranged at equal intervals in the vertical direction. The central bead 61 is an example of a "bead". The lower bead 63 and the upper bead 65 are an example of an "additional bead".

[0024] The beads 61, 63, 65 are not formed on the upper part of the flat part 52. That is, the upper part of the flat part 52 has a sticker attachment part 52a, which is an area where the beads 61, 63, 65 are not formed. A sticker (not shown) is attached to the sticker attachment part 52a. Since the sticker attachment part 52a is flat, it is easy to attach a sticker, and the attached sticker is difficult to peel off. For example, information regarding the product number, specifications, handling, etc. of the air conditioner or outdoor unit 1 is written on the sticker.

[0025] The central bead 61 is provided in the approximate center in the vertical direction in the area of ​​the flat portion 52 excluding the sticker attachment portion 52a. In detail, the distance from the lower end of the flat portion 52 to the position where the central bead 61 is provided is the distance L, the dimension of the flat portion 52 in the vertical direction is the height dimension H, and the dimension of the sticker attachment portion 52a in the vertical direction is the height dimension k, and the following inequality (A) is established. Note that FIG. 4 illustrates a range R1 from the lower end of the flat portion 52 upward to (H-k) / 2, and a range R2 from the lower end of the flat portion 52 upward to H / 2. Inequality (A) means that the central bead 61 is located inside the range R2 and outside the range R1. (Hk) / 2 <L<H / 2 (A)

[0026] Each lower bead 63 is located below the central bead 61. More specifically, each lower bead 63 is provided inside range R1 of the flat surface portion 52. Each upper bead 65 is located above the central bead 61. More specifically, each upper bead 65 is formed in a range of distances from H / 2 to (Hk) upward from the lower end of the flat surface portion 52, that is, in a range outside range R2 of the flat surface portion 52 excluding the seal attachment portion 52a.

[0027] [1-2. Operation] The operation and function of the outdoor unit 1 configured as above will be described below. As described above, when the air conditioner is in operation, the compressor 30 provided in the machine room 12 of the outdoor unit 1 operates and vibrates. Therefore, the vibration of the compressor 30 is transmitted to the exterior sheet metal part 50 that covers the machine room 12 from the left side and rear. The frequency of the vibration transmitted at this time is equal to the operating frequency of the compressor 30.

[0028] When vibration is transmitted to the exterior sheet metal part 50, if the frequency of the transmitted vibration is close to the natural frequency of the exterior sheet metal part 50, the exterior sheet metal part 50 will vibrate greatly in the natural vibration mode. In contrast, in this embodiment, beads 61, 63, and 65 are provided on the flat portion 52 to increase the rigidity of the exterior sheet metal part 50. As a result, the natural frequency of the exterior sheet metal part 50 changes to the high frequency side. In this embodiment, the natural frequency of the exterior sheet metal part 50 is higher than the operating frequency of the compressor 30 even if the beads 61, 63, and 65 are not formed. Therefore, in this embodiment, the formation of the beads 61, 63, and 65 causes the natural frequency of the exterior sheet metal part 50 to move away from the operating frequency of the compressor 30, and the vibration of the exterior sheet metal part 50 can be suppressed.

[0029] In particular, in this embodiment, the central bead 61 is provided at a position that satisfies inequality (A). Therefore, the central bead 61 increases the rigidity of the vicinity of the center in the vertical direction of the flat surface portion 52. This makes it easier to effectively shorten the length of the portion of the flat surface portion 52 that has low rigidity and is prone to vibration, and makes it easier to suppress vibration of the exterior sheet metal part 50, compared to a case in which the central bead 61 is formed at a position offset in the vertical direction. Furthermore, in this embodiment, in addition to the central bead 61, a lower bead 63 and an upper bead 65 are formed on the flat surface portion 52. Therefore, the rigidity of the flat surface portion 52 can be further increased, and it becomes easier to more effectively suppress vibration of the exterior sheet metal part 50.

[0030] [1-3. Effects, etc.] As described above, in this embodiment, the outdoor unit 1 of the air conditioner comprises an outdoor heat exchanger 17, a compressor 30, and a housing 10 that stores the outdoor heat exchanger 17 and the compressor 30, and the housing 10 has an exterior sheet metal part 50 that covers from the side the machine room 12 in which the compressor 30 is arranged, and the exterior sheet metal part 50 has a flat portion 52 formed over substantially the entire exterior sheet metal part 50 in the vertical direction, and the flat portion 52 has a seal attachment portion 52a and a central bead 61, and the central bead 61 is formed in an area of ​​the flat portion 52 excluding the seal attachment portion 52a. As a result, in the outdoor unit 1, the central bead 61 provided in an area of ​​the flat surface portion 52 excluding the seal attachment portion 52a can suppress vibration of the exterior sheet metal part 50 caused by vibration during operation of the compressor 30. Therefore, the central bead 61 can easily reduce noise caused by vibration of the exterior sheet metal part 50 without interfering with the attachment of the seal.

[0031] As in this embodiment, the central bead 61 may be formed in a straight line extending horizontally along the front-to-rear direction, which is the width direction of the flat portion 52, and may be configured to satisfy the above-mentioned inequality (A) when the dimension of the flat portion 52 in the vertical direction is H, the dimension of the sticker attachment portion 52a in the vertical direction is k, and the distance in the vertical direction from the lower end of the flat portion 52 to the central bead 61 is L. As a result, the central bead 61 is disposed approximately in the center in the up-down direction of the flat portion 52, which makes it easier to effectively shorten the up-down length of the portion with low rigidity in the flat portion 52. This makes it easier to reduce noise caused by vibration of the exterior sheet metal part 50.

[0032] As in this embodiment, the area of ​​the flat portion 52 excluding the sticker attachment portion 52a may be configured to have at least one lower bead 63 or upper bead 65 having the same shape as the central bead 61, spaced apart vertically from the central bead 61. As a result, compared to when only the central bead 61 is provided on the flat surface portion 52, the rigidity of the flat surface portion 52 can be increased by the lower bead 63 or the upper bead 65. This makes it easier to further reduce noise caused by vibration of the exterior sheet metal part 50. In particular, in this embodiment, both the lower bead 63 and the upper bead 65 are provided on the flat surface portion 52. This makes it easier to further increase the rigidity of the flat surface portion 52 and to further reduce noise caused by vibration of the exterior sheet metal part 50.

[0033] (Embodiment 2) Hereinafter, the second embodiment will be described with reference to FIG.

[0034] [2-1. Configuration] FIG. 5 is a diagram showing an exterior sheet metal part 150 according to the second embodiment as seen from the left. As shown in FIG. 5, unlike the first embodiment, the exterior sheet metal part 150 according to the second embodiment includes a central vertical bead 161, a front vertical bead 163, and a rear vertical bead 165 in the flat surface portion 52. Each of the vertical beads 161, 163, and 165 is a linear bead extending in the vertical direction. Each of the vertical beads 161, 163, and 165 is provided on the flat surface portion 52 over substantially the entire area in the vertical direction except for the seal attachment portion 52a. In this embodiment, each of the vertical beads 161, 163, and 165 has the same shape. Also, in this embodiment, each of the vertical beads 161, 163, and 165 is formed at the same position in the vertical direction and at equal intervals in the width direction. The central vertical bead 161 is an example of a "bead".

[0035] The central vertical bead 161 is provided at a position overlapping the center C of the planar portion 52 in the width direction of the planar portion 52. Strictly speaking, when the dimension of the planar portion 52 in the width direction is taken as the width dimension W, the center C of the planar portion 52 is at a position W / 2 away from the front end portion of the planar portion 52, and at least a portion of the central vertical bead 161 is located on the center C of the planar portion 52.

[0036] The front vertical bead 163 is provided at a position spaced forward from the central vertical bead 161. The rear vertical bead 165 is provided at a position spaced rearward from the central vertical bead 161.

[0037] [2-2. Effect] As a result of the vertical beads 161, 163, and 165 increasing the rigidity of the exterior sheet metal part 150 as in the first embodiment, the natural frequency of the exterior sheet metal part 150 shifts to the high frequency side and becomes a value away from the operating frequency of the compressor 30. As a result, even if the vibration of the compressor 30 is transmitted to the exterior sheet metal part 150, the exterior sheet metal part 150 is less likely to vibrate in the natural vibration mode, and the vibration of the exterior sheet metal part 150 is suppressed.

[0038] In particular, in this embodiment, a central vertical bead 161 is provided at a position overlapping the center of the flat surface portion 52 in the width direction. Therefore, the central vertical bead 161 increases the rigidity of the area near the center C. This makes it easier to effectively shorten the length of the portion of the flat surface portion 52 that has low rigidity and is prone to vibration, and makes it easier to suppress vibration of the exterior sheet metal part 150, compared to when the central vertical bead 161 is formed at a biased position in the width direction. Furthermore, in this embodiment, in addition to the central vertical bead 161, a front vertical bead 163 and a rear vertical bead 165 are formed on the flat surface portion 52. Therefore, the rigidity of the flat surface portion 52 can be further increased, and vibration of the exterior sheet metal part 150 can be more effectively suppressed.

[0039] [2-3. Effects, etc.] As in this embodiment, the central vertical bead 161 may be formed in a straight line extending in the up-down direction along the flat surface portion 52 and overlapping the center C of the flat surface portion 52 in the width direction. As a result, the central vertical bead 161 is disposed at a position overlapping with the center C of the flat surface portion 52 in the width direction, which makes it easier to effectively shorten the width direction length of the portion of the flat surface portion 52 with low rigidity. This makes it easier to reduce noise caused by vibration of the exterior sheet metal part 150. Particularly in this embodiment, in addition to the central vertical bead 161, a front vertical bead 163 and a rear vertical bead 165 are formed on the flat surface portion 52. This makes it easier to further increase the rigidity of the flat surface portion 52, and makes it easier to reduce noise caused by vibration of the exterior sheet metal part 150.

[0040] (Other embodiments) As described above, the first and second embodiments have been described as examples of the technology disclosed in this application. However, the technology in this disclosure is not limited to these, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. In addition, it is also possible to combine the components described in the first and second embodiments to create new embodiments. Therefore, other embodiments will be exemplified below.

[0041] In the first embodiment, it has been described that only the beads 61, 63, and 65 extending in the width direction are formed on the flat surface portion 52, but this is only one example. FIG. 6 is a diagram showing an exterior sheet metal part 250 in a modified example of the first embodiment as viewed from the left. For example, as shown in FIG. 6, a pair of connecting beads 267 that are connected to the width direction ends of all the beads 61, 63, and 65 in the first embodiment are further formed on the flat surface portion 52 of the modified exterior sheet metal part 250. As shown in FIG. 6, the connecting beads 267 are linear beads that extend in the vertical direction and are formed in an area of ​​the flat surface portion 52 excluding the seal attachment portion 52a.

[0042] That is, in addition to the configuration of embodiment 1, a pair of connecting beads 267 may be formed in the area of ​​the flat portion 52 excluding the seal attachment portion 52a, which are connected to the ends of the central bead 61 and to the ends of all of the lower beads 63 and upper beads 65, respectively. This makes it easier to increase the rigidity of the planar portion 52, and makes it easier to suppress vibration of the exterior sheet metal part 250.

[0043] In the first embodiment, the exterior sheet metal part 50 is described, which includes one central bead 61, four lower beads 63, and three upper beads 65 on the flat portion 52, but this is just one example. There is no particular limit to the number of the central beads 61, the lower beads 63, and the upper beads 65, as long as one or more beads are formed by combining the respective beads 61, 63, and 65. In other words, the application of the present disclosure is not limited to the case where the central bead 61 that satisfies the inequality (A) is formed. However, by forming one or more central beads 61 that satisfy the inequality (A), it is easy to efficiently suppress the vibration of the exterior sheet metal part 50.

[0044] In the second embodiment, the exterior sheet metal part 150 is described in which one central vertical bead 161, one front vertical bead 163, and one rear vertical bead 165 are provided on the flat surface part 52, but this is only one example. There is no particular limit to the number of the central vertical bead 161, the front vertical bead 163, and the rear vertical bead 165, as long as the vertical beads 161, 163, and 165 together form one or more beads. In other words, the central vertical bead 161 overlapping the center of the flat surface part 52 in the width direction does not necessarily have to be provided. However, by providing the central vertical bead 161 overlapping the center of the flat surface part 52 in the width direction, it is easy to efficiently suppress vibration of the exterior sheet metal part 150.

[0045] In the first embodiment, the exterior sheet metal part 50 has been described as having the left side surface portion 51 and the left rear surface portion 53, but this is just one example. It is sufficient that the exterior sheet metal part 50 has a surface provided with the flat surface portion 52, the sticker attachment portion 52a, and one or more beads formed in an area of ​​the flat surface portion 52 excluding the sticker attachment portion 52a. That is, for example, in the first embodiment, the left rear surface portion 53 does not have to be formed on the exterior sheet metal part 50.

[0046] In the above embodiment, the beads 61, 63, 65 have the same shape, and the vertical beads 161, 163, 165 have the same shape, but this is only an example and they may have different shapes. Also, in the above embodiment, the beads 61, 63, 65 and the vertical beads 161, 163, 165 are arranged at equal intervals, but this is only an example and they may be arranged at different intervals.

[0047] It should be noted that the above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, and the like can be made within the scope of the claims or their equivalents.

[0048] [Configuration supported by the above embodiment] The above embodiment supports the following configurations.

[0049] (Supplementary Note) (Technology 1) An outdoor unit of an air conditioner includes an outdoor heat exchanger, a compressor, and a housing that houses the outdoor heat exchanger and the compressor. The housing has an exterior sheet metal component that covers the machine room where the compressor is disposed from the side. The exterior sheet metal component has a flat portion formed over substantially the entire exterior sheet metal component in the vertical direction. The flat portion has a seal attachment portion and a bead. The bead is formed in a region of the flat portion excluding the seal attachment portion.

[0050] Thus, the bead provided in the region of the flat portion excluding the seal attachment portion can suppress the vibration of the exterior sheet metal component due to the vibration during the driving of the compressor. Therefore, it is easy to reduce the noise caused by the vibration of the exterior sheet metal component without hindering the attachment of the seal by the bead.

[0051] (Technology 2) The bead is formed in a linear shape extending horizontally along the width direction of the flat portion. Let the dimension of the flat portion in the vertical direction be H, the dimension of the seal attachment portion in the vertical direction be k, and the distance in the vertical direction from the lower end of the flat portion to the bead be L. The outdoor unit of the air conditioner according to Technology 1 satisfies the following inequality (A). (H - k) / 2 < L < H / 2 (A)

[0052] Thus, since the bead is disposed approximately at the center in the vertical direction of the flat portion, it is easy to effectively shorten the length in the vertical direction of the portion with low rigidity in the flat portion by the bead. Therefore, it is easy to reduce the noise caused by the vibration of the exterior sheet metal component.

[0053] (Technology 3) In the region of the flat portion excluding the seal attachment portion, at least one additional bead having the same shape as the bead is provided at a position vertically spaced apart from the bead. The outdoor unit of the air conditioner according to Technology 2.

[0054] This makes it possible to further increase the rigidity of the flat portion by the additional upper bead, compared to a case in which only a bead is provided on the flat portion, and therefore makes it easier to reduce noise caused by vibration of the exterior sheet metal part.

[0055] (Technology 4) In an outdoor unit of an air conditioner described in Technology 3, a pair of connecting beads are formed in the area of ​​the flat portion excluding the seal attachment portion, the connecting beads being connected to the ends of the beads and all of the additional beads, respectively.

[0056] This makes it easier to further increase the rigidity of the planar portion, and makes it easier to suppress vibrations of the exterior sheet metal part.

[0057] (Technical 5) In the outdoor unit for an air conditioner according to Technical 1, the bead is formed in a straight line extending in the vertical direction along the planar portion and overlaps with the center in the width direction of the planar portion.

[0058] As a result, the bead is disposed approximately at the center in the width direction of the flat surface portion, and the length of the flat surface portion in the width direction where the rigidity is low can be effectively shortened by the bead, which makes it easier to reduce noise caused by vibration of the exterior sheet metal part.
