Description

[Technical field]

[0001] The present disclosure relates to an outdoor unit and an air conditioner. [Background technology]

[0002] An air conditioner is equipped with an outdoor unit that houses a compressor that constitutes a refrigeration cycle. Noise is generated from the outdoor unit due to the operating sound emitted when the compressor compresses a refrigerant.

[0003] The outdoor unit disclosed in Patent Document 1 is equipped with a noise absorbing device, which is a Helmholtz resonator that attenuates the operating noise emitted from the compressor. This noise absorbing device includes a groove formed in a base plate, and a sound absorbing plate that entirely blocks the opening of the groove and has a hole that leads to the inside of the groove. The compressor is located directly above the noise absorbing device.

[0004] The operating noise from the compressor is radiated into the groove through the hole. As a result, the air inside the groove repeatedly compresses and expands, causing the air to vibrate inside the hole. Viscous friction occurs between the vibrating air and the hole. This attenuates the noise from the compressor. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2012-37148 A Summary of the Invention [Problem to be solved by the invention]

[0006] The Helmholtz resonator attenuates sound by having a resonant frequency that resonates with a specific frequency of sound. The resonant frequency is related to the volume of the space inside the resonator, the opening that leads to the space, and the length of the opening axis.

[0007] The space of the sound absorbing device disclosed in Patent Document 1 is a space defined by the sound absorbing plate completely blocking the opening of the groove. In other words, the resonance frequency of the sound absorbing device depends on the total internal volume of the groove. Therefore, with the technology disclosed in Patent Document 1, every time the sound absorbing device is mounted on the base plate, it is necessary to design a groove with a volume that resonates with the operating sound and form it on the base plate, which is time-consuming. Therefore, there is a concern that the sound absorbing device cannot be easily mounted on the base plate.

[0008] An object of the present disclosure is to provide an outdoor unit and an air conditioner in which a sound absorbing device for attenuating operating noise from a compressor can be easily provided on a base plate. [Means for solving the problem]

[0009] In order to achieve the above object, the outdoor unit according to the present disclosure comprises: a housing having a base plate with a groove extending on a surface thereof; a compressor housed in the housing and configured to compress a refrigerant; A partition member disposed in the groove of the base plate; Equipped with The partition member is a plate-like portion extending in an extension direction of the groove portion and covering an opening of the groove portion; a partition portion extending from the plate portion in a direction intersecting an extension direction of the groove portion and partitioning an inside of the groove portion; a second partition portion extending from the plate-like portion in a direction intersecting the extending direction of the groove portion at a position away from the first partition portion and partitioning the inside of the groove portion; having the plate-shaped portion, the one partition portion, and the other partition portion define a plurality of spaces that are closed in an extension direction of the groove portion, At least one of the portion of the base plate forming the groove and the plate-like portion has a through hole that communicates between the inside of the housing and the space. Effect of the Invention

[0010] According to the above-mentioned configuration, by simply arranging the partition member in the groove, the plate-shaped portion, one partition portion, and the other partition portion can partition and form a plurality of spaces that are closed in the extension direction of the groove. Therefore, there is no need to design and form a groove with a volume that resonates with the operating sound every time a sound absorbing device is attached to the base plate. Therefore, the sound absorbing device can be easily attached to the base plate. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an outdoor unit and an air conditioner according to an embodiment will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

[0013] [Embodiment 1] As shown in Fig. 1, the air conditioner 9 includes an indoor unit 8 installed in the indoor (ID) of the facility and an outdoor unit 7 installed in the outdoor (OD). The air conditioner 9 uses the indoor unit 8 and the outdoor unit 7 to cool or heat the indoor air (IA), which is the air in the indoor ID, and supplies conditioned air (CA) to the indoor ID.

[0014] The indoor unit 8 has an indoor blower 81 that forms an airflow, and an indoor heat exchanger 82 that evaporates or condenses a refrigerant. The indoor blower 81 and the indoor heat exchanger 82 are housed in the interior Sa of the housing 80. The housing 80 is formed with an air intake 80a and an air outlet 80b. The interior Sa of the housing 80 is in communication with the indoor ID via the air intake 80a and the air outlet 80b.

[0015] The indoor blower 81 forms an airflow in the interior Sa of the housing 80, in which the indoor air IA flows from the intake port 80a toward the air outlet 80b. The indoor heat exchanger 82 is disposed at a position where the airflow of the indoor air IA hits. The indoor air IA undergoes heat exchange with the indoor heat exchanger 82, and becomes cooled or heated conditioned air CA. The conditioned air CA is blown out from the air outlet 80b to the indoors ID.

[0016] The outdoor unit 7 has an outdoor blower 71 that forms an airflow, an outdoor heat exchanger 72 that condenses or evaporates the refrigerant, an expander 73 that expands the refrigerant, and a compressor 60 that compresses the refrigerant. The outdoor blower 71, the outdoor heat exchanger 72, the expander 73, and the compressor 60 are housed in the interior Sb of a housing 70. An intake port 70a and an exhaust port 70b are formed in the housing 70. The interior Sb of the housing 70 and the outdoor OD are in communication with each other via an intake port 80a and an exhaust port 80b.

[0017] The outdoor blower 71 forms an airflow in the interior Sb of the housing 70, in which the outside air OA, which is outdoor OD air, flows from the intake port 70a toward the exhaust port 70b. The outdoor heat exchanger 72 is disposed at a position where the airflow of the outside air OA hits the outdoor heat exchanger 72. The outside air OA undergoes heat exchange with the indoor heat exchanger 82, and becomes heated or cooled exhaust air EA. The exhaust air EA is blown out from the exhaust port 70b to the outdoor OD.

[0018] The indoor unit 8 and the outdoor unit 7 are connected to each other by a refrigerant pipe 91 through which a refrigerant passes. The refrigerant pipe 91 connects the compressor 60, the outdoor heat exchanger 72, the expander 73, and the indoor heat exchanger 82 in a ring shape in this order. This forms a refrigeration cycle in which the refrigerant circulates.

[0019] In the refrigeration cycle, when the compressor 60 compresses the refrigerant, an operating sound is emitted from the compressor 60. The operating sound emitted from the compressor 60 is transmitted to the housing 70, and generates noise from the outdoor unit 7. To prevent users of the facility from sensing this noise, measures are required to attenuate the operating sound emitted from the compressor 60.

[0020] As a countermeasure, as disclosed in Patent Document 1, a configuration in which a silencer, which is a Helmholtz resonator, is arranged near the compressor is considered. A conventional silencer is composed of a groove formed in a base plate and a sound absorbing plate that covers the opening of the groove and has a hole leading to the inside of the groove. The conventional silencer is composed of a single Helmholtz resonator. On the other hand, the operating sound is radiated from the compressor to the entire inside of the housing. Therefore, there is a concern that the operating sound that is not radiated to the silencer and is not attenuated will penetrate the housing and leak to the outside.

[0021] To address such concerns, it is conceivable to provide a separate silencer near the compressor. In that case, in the outdoor unit disclosed in Patent Document 1, it is conceivable to form a new groove in the portion of the base plate where the compressor is located.

[0022] However, the portion of the base plate where the compressor is located has limited space, making it difficult to form multiple grooves, and as a result, there is a concern that it may be difficult to provide a new silencer near the compressor.

[0023] Therefore, the outdoor unit according to the present embodiment is configured to be able to easily provide a plurality of silencers, which are Helmholtz resonators, without being restricted by space near the compressor. The configuration will be described in detail below.

[0024] As shown in Fig. 2, the housing 70 of the outdoor unit 7 is formed into a hollow vertically long box shape by a top plate 70c, a front plate 70d, a rear plate 70e, a right side plate 70f, a left side plate 70g, and a base plate 10 which is a bottom plate. For ease of understanding, Fig. 2 shows an XYZ Cartesian coordinate system in which the width direction of the outdoor unit 7, i.e., the longitudinal direction of the base plate 10, when the front plate 70d of the outdoor unit 7 is the front, is the X-axis direction, the height direction of the outdoor unit 7, i.e., the thickness direction of the base plate 10, is the Y-axis direction, and the depth direction of the outdoor unit 7, i.e., the short side direction of the base plate 10, is the Z-axis direction when the front plate 70d of the outdoor unit 7 is the front. The same applies to Figs. 3 to 16 which will be referred to later.

[0025] An intake port 70a is formed in the right side plate 70f and the rear side plate 70e. The outdoor heat exchanger 72 is disposed in the interior Sb of the housing 70 at a position facing the intake port 70a. An exhaust port 70b is formed in the top plate 70c. The outdoor blower 71 is disposed at a position facing the exhaust port 70b of the top plate 70c.

[0026] 3, the base plate 10 is a plate member having a rectangular shape in a plan view. A first leg 11 and a second leg 12 are provided at both ends in the short side direction of the base plate 10. The first leg 11 and the second leg 12 extend in the long side direction of the base plate 10.

[0027] Furthermore, the base plate 10 has a cross section perpendicular to the longitudinal direction formed with a concave-convex shape by a plurality of concave portions and a plurality of convex portions 30 which are continuous in the longitudinal direction and extend linearly parallel to the lateral direction.

[0028] The compressor 60, an outdoor heat exchanger (not shown), and an expander (not shown) are disposed on the upper surface 10b of the base plate 10, which is the surface facing the inside of the housing 70. A first piping insertion port 10c and a second piping insertion port 10d are formed in the portion of the base plate 10 where the outdoor heat exchanger is located. The first piping insertion port 10c and the second piping insertion port 10d are openings for passing a refrigerant piping 91 connected to the indoor heat exchanger 82 and for ensuring a working space when brazing the refrigerant piping 91.

[0029] The compressor 60 is cylindrical and is provided upright on the base plate 10 with the axis of the cylinder directed perpendicular to the upper surface 10b of the base plate 10. The compressor 60 has a first connection pipe 63a, a second connection pipe 63b, and a third connection pipe 63c to which the refrigerant pipe 91 is connected at the upper portion.

[0030] The compressor 60 also has a first support leg 61a, a second support leg 61b, a third support leg 61c, and a fourth support leg (not shown) at its lower end. The first support leg 61a, the second support leg 61b, the third support leg 61c, and the fourth support leg each extend radially outward around the cylinder axis of the compressor 60 in a plan view, and extend downward in a side view. An elastic member 62 for vibration isolation is provided at the lower end of each of the first support leg 61a, the second support leg 61b, the third support leg 61c, and the fourth support leg. The elastic member 62 is provided in a state where it is elastically sandwiched between the support leg and the base plate 10.

[0031] The compressor 60 is provided on the upper surface 10b of the base plate 10, straddling a first protrusion 31 and a second protrusion 32 among the multiple protrusions 30. A third protrusion 33 is located between the first protrusion 31 and the second protrusion 32. The third protrusion 33 is a portion of the plate surface of the base plate 10, the cross section perpendicular to the extending direction of the base plate 10 being formed to protrude upward toward the inside Sb of the housing 70.

[0032] The inside of the third protrusion 33 corresponds to a first groove 201, which is a groove 20 that extends linearly on the bottom surface 10a of the base plate 10, which is the surface facing the outside of the housing 70, and has a downward opening. The first groove 201 is recessed from the bottom surface 10a, which is the outer surface of the housing 70, to the top surface 10b, which is the inner surface, in a direction perpendicular to the extending direction. The compressor 60 is located above the first groove 201.

[0033] As shown in FIG. 4, the first groove portion 201 is formed in the base plate 10 by a first flange 21, a second flange 22, and a web 23, each of which has a strip-like shape.

[0034] The first flange 21 and the second flange 22 each extend in a direction intersecting the extension direction of the base plate 10. In detail, the first flange 21 and the second flange 22 are parallel to and spaced apart from each other, and each extend in a direction perpendicular to the extension direction of the base plate 10 and in the short direction.

[0035] The web 23 extends parallel to the extension direction of the base plate 10. In detail, the web 23 extends between the upper end of the first flange 21 and the upper end of the second flange 22, and in the short direction of the base plate 10. The upper surface of the web 23 is the upper surface 10b of the base plate 10 that is parallel to the bottom surface 60a of the compressor 60.

[0036] As shown in FIG. 6, the second flange 22 is formed with a through hole 50 that communicates the inside Sb of the housing 70 shown in FIG. 1 with the inside of the first groove portion 201. The through hole 50 is an opening of a Helmholtz resonator through which the operating sound from the compressor 60 is emitted. As shown in FIG. 4, the through hole 50 has a first through hole 501, a second through hole 502, a third through hole 503, a fourth through hole 504, a fifth through hole 505, a sixth through hole 506, and a seventh through hole 507 that are formed at equal intervals in the extending direction of the second flange 22. Each of the first through hole 501 to the seventh through hole 507 is formed with the same opening area and the same hole length. The hole axis direction of each of the first through hole 501 to the seventh through hole 507 is a direction that is inclined with respect to the bottom surface 60a of the compressor 60.

[0037] Further, a first partition member 401, which is the partition member 40, is disposed in the first groove portion 201. The first partition member 401 is made of metal, and has a band-shaped plate portion 41 and a plate-shaped partition portion 42, as shown in FIG.

[0038] The plate-shaped portion 41 is a portion that covers the lower opening of the first groove portion 201 when the first partition member 401 is disposed in the first groove portion 201. The plate-shaped portion 41 extends in the extension direction of the first groove portion 201 with the plate surface parallel to the opening surface of the lower opening of the first groove portion 201. The bottom surface of the plate-shaped portion 41 is flush with the bottom surface 10a of the base plate 10 when covering the lower opening of the first groove portion 201.

[0039] The area of ​​the plate surface of the plate-like portion 41 is larger than the area of ​​the bottom surface 60a of the compressor 60 facing the upper surface 10b of the base plate 10. Although details will be described later, among the multiple first spaces S1 to S7 defined in the extension direction of the first groove portion 201 by the first partition member 401, the second space S2 and the third space S3 are located facing the bottom surface 60a of the compressor 60. In other words, the area of ​​the upper surface of the first silencer group G1 to which the first silencer H1 to the seventh silencer H7 are connected is larger than the bottom surface 60a of the compressor 60. As a result, the operation noise from the compressor 60 is picked up over a wide range by the first silencer H1 to the seventh silencer H7 and is effectively attenuated.

[0040] The partition portion 42 is a flat plate-like portion that extends in the width direction and partitions the inside of the first groove portion 201 when the first partition member 401 is placed in the first groove portion 201. The partition portion 42 serves to partition the inside of the first groove portion 201 into a plurality of spaces and also serves as a beam that prevents the first groove portion 201 from buckling and vibration.

[0041] The partition portion 42 includes a first partition portion 421, a second partition portion 422, a third partition portion 423, a fourth partition portion 424, a fifth partition portion 425, a sixth partition portion 426, a seventh partition portion 427, and an eighth partition portion 428, which are arranged at equal intervals in the extension direction of the plate-shaped portion 41 and whose plate surfaces are parallel to each other.

[0042] Each of the first partition portion 421 to the eighth partition portion 428 has a shape that can be fitted into the first groove portion 201. Each of the first partition portion 421 to the eighth partition portion 428 extends from the plate-shaped portion 41 in an upward direction perpendicular to the extension direction of the first groove portion 201 and in the width direction of the first groove portion 201. Each of the first partition portion 421 to the eighth partition portion 428 extends between the plate-shaped portion 41 and the web 23 of the first groove portion 201 and between the first flange 21 and the second flange 22 of the first groove portion 201 when the first partition member 401 is placed in the first groove portion 201.

[0043] Further, the first partition portion 421 and the eighth partition portion 428 each have a first fixing portion 441 and a second fixing portion 442 which are fixing portions 44 for fixing the first partition member 401 to the base plate 10. The first fixing portion 441 and the second fixing portion 442 each extend outward in the extending direction of the plate-shaped portion 41 from the end portions of the first partition portion 421 and the eighth partition portion 428. The first fixing portion 441 and the second fixing portion 442 abut against the web 23 of the first groove portion 201, and are fixed by screws which are fixing members (not shown).

[0044] As shown in Fig. 4, when the first partition member 401 is placed in the first groove portion 201, the inside of the first groove portion 201 is partitioned and divided into a first space S1, a second space S2, a third space S3, a fourth space S4, a fifth space S5, a sixth space S6, and a seventh space S7 by the first partition member 401. Each of the first space S1 to the seventh space S7 corresponds to a closed internal space of a Helmholtz resonator. Each of the first space S1 to the seventh space S7 has the same volume.

[0045] The first space S1 to the seventh space S7 are formed between adjacent partition parts of the first partition part 421 to the eighth partition part 428. In other words, as shown in Fig. 6, the inside of the groove part 20 is partitioned into one space S that is partially closed by the partition element 43 including one partition part 42 and the other partition part 42 adjacent to each other and the plate-shaped part 41.

[0046] The space S communicates with the interior Sb of the housing 70 via the through hole 50. In this manner, the partition element 43 is disposed in the first groove portion 201 together with the plate-shaped portion 41, thereby partially configuring a silencer H, which is a Helmholtz resonator. As shown in FIG. 5, the partition element 43 has a first partition element 431 to a seventh partition element 437 arranged side by side in the extending direction of the plate-shaped portion 41.

[0047] The first partition element 431 to the seventh partition element 437, together with the plate-shaped portion 41, divide the inside of the first groove portion 201 into a first space S1 to a seventh space S7. The first through hole 501 to the seventh through hole 507 of the first groove portion 201 are located in the first space S1 to the seventh space S7, respectively.

[0048] By arranging the first partition member 401 in the first groove portion 201 in this manner, a first silencer group G1 in which the first silencer H1 to the seventh silencer H7, each of which is a Helmholtz resonator, are connected together, is provided on the base plate 10.

[0049] The second silencer H2 and the third silencer H3 of the first silencer group G1 are located directly below the compressor 60 in a plan view. The top surfaces of the second silencer H2 and the third silencer H3 face the bottom surface of the compressor 60. The first silencer H1 and the fourth silencer H4 to the seventh silencer H7 of the first silencer group G1 are located outside the compressor 60 in a plan view.

[0050] The operation noise from the compressor 60 is effectively attenuated by the first silencer group G1. The operation noise from the compressor 60 is radiated from the first through hole 501 to the seventh through hole 507 of the first silencer H1 to the seventh silencer H7, respectively, to the first space S1 to the seventh space S7. As a result, the air in the first space S1 to the seventh space S7 is repeatedly compressed and expanded. Then, the air in the first through hole 501 to the seventh through hole 507 vibrates. Viscous friction occurs between the air and the first through hole 501 to the seventh through hole 507. As a result, the operation noise from the compressor 60 is attenuated.

[0051] Thus, according to the outdoor unit 7 of the present embodiment, the interior of the groove portion 20 can be partially divided into a plurality of first space S1 to seventh space S7 by the partition member 40 having the plurality of first partition elements 431 to seventh partition elements 437. Therefore, the first silencer H1 to seventh silencer H7, which are a plurality of Helmholtz resonators, can be easily provided on the base plate 10 without being restricted by space near the compressor 60.

[0052] [Embodiment 2] 4 illustrates a configuration in which the through hole 50 is formed in the second flange 22 of the first groove portion 201. However, the position where the through hole 50 of the first groove portion 201 is formed is not limited to this. A specific example will be described below.

[0053] 7, in the present embodiment, the through holes 50 are formed in the web 23, which is a portion parallel to the extending direction of the base plate 10, in the first groove portion 201. A plurality of through holes 50 are formed in the center of the web 23 in the width direction and at equal intervals in the extending direction of the web 23.

[0054] The through hole 50 has a first through hole 501 to a seventh through hole 507 which communicate with the first space S1 to the seventh space S7 of the first silencer H1 to the seventh silencer H7, respectively. The hole axis direction of each of the first through hole 501 to the seventh through hole 507 is perpendicular to the bottom surface 60a of the compressor 60.

[0055] In this embodiment as well, the operation noise from the compressor 60 can be effectively attenuated by the first silencer H1 to the seventh silencer H7. In particular, in this embodiment, the first through-hole 501 to the seventh through-hole 507 are formed in the web 23 facing the bottom surface 60a of the compressor 60, so that the operation noise from the bottom surface 60a of the compressor 60 is likely to be radiated to the second silencer H2 and the third silencer H3 located directly below. This improves the efficiency of attenuating the operation noise.

[0056] [Embodiment 3] 4 illustrates a configuration in which the groove portion 20 is a first groove portion 201 formed on the bottom surface 10a of the base plate 10. Also illustrated is a configuration in which a first through hole 501 to a seventh through hole 507, through which the inside of the housing 70 communicates with the first space S1 to the seventh space S7, respectively, are formed in a portion of the base plate 10 to which the first groove portion 201 extends. However, the positions at which the groove portion 20 and the through hole 50 are formed are not limited to this. Specific examples thereof will be described below.

[0057] The groove 20 in this embodiment is a second groove 202 that extends linearly in a plan view on the upper surface 10b of the base plate 10, which is the surface facing the inside of the housing 70. The second groove 202 corresponds to a recess located between the first protrusion 31 and the second protrusion 32 on which the compressor 60 (not shown) is placed. As shown in FIG. 8, the second groove 202 is recessed from the upper surface 10b, which is the inner surface of the housing 70, toward the bottom surface 10a, which is the outer surface, in a direction perpendicular to the extension direction. The compressor 60 is located above the second groove 202.

[0058] The second groove portion 202 is formed by a band-shaped first flange 21, a second flange 22, and a web 23. The first flange 21 and the second flange 22 are parallel to each other and spaced apart from each other, and extend in the plate thickness direction and the short side direction of the base plate 10. The web 23 extends between the lower end of the first flange 21 and the lower end of the second flange 22, and in the short side direction of the base plate 10.

[0059] A second partition member 402 is disposed in the second groove portion 202. The second partition member 402 is made of metal, and has a band-shaped plate portion 41 and a plate-shaped partition portion 42, as shown in FIG.

[0060] The plate-shaped portion 41 covers the upper opening of the second groove portion 202 when the second partition member 402 is disposed in the second groove portion 202. The plate-shaped portion 41 extends in the extension direction of the second groove portion 202 with the plate surface parallel to the opening surface of the upper opening of the second groove portion 202. The upper surface of the plate-shaped portion 41 is flush with the upper surface 10b of the base plate 10 when covering the upper opening of the first groove portion 201.

[0061] The partitions 42 are disposed at equal intervals in the extending direction of the plate-shaped portion 41, and include a first partition 421 to an eighth partition 428 whose plate surfaces are parallel to one another. With the second partition member 402 disposed in the second groove portion 202, the partitions 42 traverse and partition the inside of the second groove portion 202.

[0062] Further, the first partition portion 421 and the eighth partition portion 428 have a first fixing portion 441 and a second fixing portion 442 for fixing the second partition member 402 to the base plate 10. The first fixing portion 441 and the second fixing portion 442 abut against the bottom surface of the web 23 of the second groove portion 202, and are fixed to the base plate 10 by screws (not shown).

[0063] By arranging such a second partition member 402 in the second groove portion 202, the interior of the second groove portion 202 is defined into a first space S1 to a seventh space S7, which are the internal spaces of the Helmholtz resonator, as shown in Figures 8 and 10.

[0064] The plate-like portion 41 of the second partition member 402 is formed with a first through hole 501 to a seventh through hole 507 through which the first space S1 to the seventh space S7 communicate with the interior Sb of the housing 70 shown in FIG.

[0065] Specifically, the first through hole 501 to the seventh through hole 507 are formed in the center in the width direction of the plate-shaped portion 41 and at equal intervals in the extension direction of the plate-shaped portion 41. The hole axis direction of each of the first through hole 501 to the seventh through hole 507 is perpendicular to the bottom surface 60a of the compressor 60 shown in FIG.

[0066] By arranging such a second partition member 402 in the second groove portion 202, a second silencer group G2 in which the first silencer H1 to the seventh silencer H7, each of which is a Helmholtz resonator, are connected together, is provided on the base plate 10.

[0067] In this embodiment as well, the operating noise from the compressor 60 is effectively attenuated by each of the first silencer H1 to the seventh silencer H7. Particularly in this embodiment, the work of arranging the second partition member 402 in the second groove portion 202 and the work of arranging the compressor 60 are completed on the upper surface 10b side of the base plate 10. This makes it easy to perform the layout work of determining the relative positions of the compressor 60 and the first silencer H1 to the seventh silencer H7.

[0068] [Embodiment 4] 5 illustrates a configuration in which the first fixing portion 441 and the second fixing portion 442 are provided on the first partition portion 421 and the eighth partition portion 428 located at both ends in the extending direction of the plate-shaped portion 41. However, the number of partition portions 42 and fixing portions 44 is not limited to this. These will be described below.

[0069] As shown in Figure 11, the first partition member 401 of this embodiment has three partition portions, namely, a first partition portion 421 to a third partition portion 423, in the extension direction of the plate-shaped portion 41, and the first partition portion 421 to the third partition portion 423 have a fixing portion 44.

[0070] The second partition portion 422 has a cross section perpendicular to the extending direction of the plate-shaped portion 41 formed in a convex shape extending upward in the thickness direction of the plate-shaped portion 41. The first partition portion 421 to the third partition portion 423 each have a first fixing portion 441 to a third fixing portion 443 for fixing the first partition portion 421 to the base plate 10, respectively.

[0071] The first fixing portion 441 and the second fixing portion 442 extend outward in the extending direction of the plate-shaped portion 41 from the ends of the first partition portion 421 and the second partition portion 422, respectively. The third fixing portion 443 is a flat portion corresponding to the top of the convexity of the second partition portion 422.

[0072] By arranging such a first partition member 401 in the first groove portion 201, a first silencer group G1 in which the first silencers H1 and the second silencers H2 are connected together is provided on the base plate 10.

[0073] 3. That is, the first space S1 and the second space S2 defined in the extending direction of the first groove portion 201 are all positioned opposite the bottom surface 60a of the compressor 60. In other words, the area of ​​the upper surface of the first silencer group G1 including the first silencer H1 and the second silencer H2 is smaller than the area of ​​the bottom surface 60a of the compressor 60.

[0074] As a result, the operation noise emitted from the compressor 60 can be concentrated and attenuated by the first silencer H1 and the second silencer H2. That is, the number of constituent silencers H can be appropriately increased or decreased according to the operation noise from the compressor 60 equipped in the outdoor unit 7. Therefore, design costs and material costs can be reduced.

[0075] Moreover, the partition member 40 is fixed to the base plate 10 not only by the first fixing portion 441 and the second fixing portion 442 located at both ends in the extension direction, but also by the third fixing portion 443 located in the middle portion. Therefore, the fixed state of the partition member 40 to the base plate 10 can be made more firmly.

[0076] [Embodiment 5] 4 illustrates a configuration in which the first space S1 to the seventh space S7 have the same volume, and the first through hole 501 to the seventh through hole 507 have the same opening area and hole length, that is, a configuration in which a plurality of first silencers H1 to H7 have the same resonance frequency. The compressor housed in the outdoor unit is selected from those having the performance of compressing the refrigerant according to the size of the facility in which the air conditioner is installed. Therefore, the operating noise emitted differs for each selected compressor.

[0077] Furthermore, the operating sound emitted from a compressor is usually a composite sound in which multiple sound components with different frequencies are superimposed. If multiple silencers have the same resonant frequency, the sound attenuated by each silencer is limited to a single sound that constitutes the composite sound. Therefore, there is a concern that the sound that is not attenuated by each silencer will leak out to the outside as noise from the outdoor unit. Therefore, in this embodiment, a second silencer H2 and a third silencer H3, each having a different resonant frequency, are provided. A specific example will be described below.

[0078] 12, in the first partition member 401 of the present embodiment, the intervals between the second partition portion 422 to the fourth partition portion 424 provided on the plate-shaped portion 41 are not the same. The second through hole 502 and the third through hole 503 formed in the first groove portion 201 are formed to have the same opening area and the same hole length.

[0079] In detail, the distance L1 between the third partition portion 423 and the fourth partition portion 424 which are the third partition element 433 is shorter than the distance L2 between the second partition portion 422 and the third partition portion 423 which are the second partition element 432. Therefore, when the partition member 40 is disposed in the groove portion 20, the volume of the third space S3 is smaller than the volume of the second space S2.

[0080] In other words, the third silencer H3 has a resonance frequency in a higher frequency band than the second silencer H2. Therefore, of the composite sound, which is the operating sound emitted from the compressor 60, the low frequency sound is attenuated by the second silencer H2, and the higher frequency sound is attenuated by the third silencer H3.

[0081] In this manner, in the present embodiment, by varying the distances at which the first partition portions 421 to the fourth partition portions 424 are spaced apart from one another, it is possible to attenuate the different frequency sounds that constitute the operating sound emitted from the compressor 60. As a result, it is possible to further reduce the noise generated from the outdoor unit 7.

[0082] [Embodiment 6] 4 illustrates a configuration in which a first partition member 401 has a first partition portion 421 to an eighth partition portion 428 aligned in the extending direction of the plate-shaped portion 41 to partition the inside of the groove portion 20. However, the configuration of the partition portions 42 is not limited to this. Specific examples will be described below.

[0083] 13, the first partition member 401 of the present embodiment further has a strip-shaped intermediate partition portion 429 extending between the first partition portion 421 to the eighth partition portion 428 and in the extending direction of the first groove portion 201. Note that, of the eight first partition portion 421 to the eighth partition portion 428, only the second partition portion 422, the third partition portion 423, and the fourth partition portion 424 are shown in FIG. 13, and the other partition portions 42 are omitted.

[0084] The intermediate partition 429 is located at the center in the width direction of the web 23, i.e., the center in the width direction of the first groove portion 201. The intermediate partition 429 extends with its plate surface parallel to the inner surfaces of the first flange 21 and the second flange 22 of the first groove portion 201. The extending direction of the intermediate partition 429 is a direction perpendicular to the plate surfaces of each of the first partition portion 421 to the eighth partition portion 428.

[0085] With such a first partition member 401 disposed in the first groove portion 201, the inside of the first groove portion 201 is divided into 14 spaces S. There are two spaces S arranged in the width direction of the first groove portion 201, and seven spaces S arranged in the extension direction of the first groove portion 201. Note that, of the 14 spaces S, only the second space S2, the third space S3, the ninth space S9, and the tenth space S10 are shown in Fig. 13, and the other spaces S are omitted.

[0086] In addition, the first flange 21 and the second flange 22 of the first groove portion 201 are formed with 14 through holes 50 that communicate with the 14 spaces, respectively. That is, 14 silencers H are configured in one first groove portion 201. Note that, in FIG. 13, of the 14 through holes 50, only the second through hole 502 communicating with the second space S2, the third through hole 503 communicating with the third space S3, the ninth through hole 509 communicating with the ninth space S9, and the tenth through hole 510 communicating with the tenth space S10 are shown, and the other through holes 50 are omitted. In addition, in FIG. 13, of the 14 silencers H, only the second silencer H2, the third silencer H3, the ninth silencer H9, and the tenth silencer H10 are shown, and the other silencers H are omitted.

[0087] In this manner, also in the present embodiment, the partition member 40 has a plurality of the first partition portions 421 to eighth partition portion 428 and the intermediate partition portion 429, so that the inside of the groove portion 20 can be divided into a plurality of spaces S. That is, without being restricted by the space of the base plate 10 near the compressor 60, the first silencer H1 to fourteenth silencer (not shown), which are Helmholtz resonators, can be arranged side by side in the extension direction of the first groove portion 201 and in the width direction perpendicular to the extension direction.

[0088] [Embodiment 7] Fig. 7 illustrates a configuration in which a single first silencer group G1 is provided on the base plate 10, and Fig. 8 illustrates a configuration in which a single second silencer group G2 is provided on the base plate 10. However, the first silencer group G1 and the second silencer group G2 may be provided on one base plate 10. A specific example will be described below.

[0089] 14, in this embodiment, the first silencer group G1 and the second silencer group G2 are adjacent to each other and provided on the base plate 10. The first silencer group G1 has a first groove portion 201 and a first partition member 401. The second silencer group G2 has a second groove portion 202 and a second partition member 402.

[0090] The first groove portion 201 and the second groove portion 202 correspond to the insides of the continuous recessed portion and protruding portion in a cross section perpendicular to the longitudinal direction of the base plate 10. The first groove portion 201 and the second groove portion 202 are adjacent to each other and extend parallel to each other. The first groove portion 201 and the second groove portion 202 are located on the base plate 10 between the first protruding portion 31 and the second protruding portion shown in FIG. 3. The compressor 60 is disposed straddling the first protruding portion 31 and the second protruding portion 32.

[0091] That is, the compressor 60 is disposed at a position overlapping the first silencer group G1 and the second silencer group G2 in a plan view on the base plate 10. In detail, the second silencer H2 and the third silencer H3 of the first silencer group G1 and the second silencer group G2, respectively (not shown), are disposed directly below the compressor 60.

[0092] In this embodiment as well, the operation noise from the compressor 60 is radiated intensively to the second silencer H2 and the third silencer H3 of the first silencer group G1 and the second silencer group G2, respectively, and is attenuated. The operation noise is also radiated to the surrounding silencers and is attenuated.

[0093] In this way, according to the outdoor unit 7 of the present embodiment, the two first and second silencer groups G1 and G2 can be arranged side by side without being restricted by space near the compressor 60. In these two groups, the first and second silencer groups G1, G2, the first to seventh silencers H1 to H7 can pick up and attenuate a wide range of operating noise radiated from the compressor 60. Therefore, the noise from the outdoor unit 7 can be further reduced.

[0094] [Embodiment 8] Fig. 3 illustrates a configuration in which the outdoor unit 7 includes one compressor 60. Fig. 14 illustrates a configuration in which two silencer groups, a first silencer group G1 and a second silencer group G2, are provided adjacent to each other on the base plate 10. However, the number of compressors 60 and the relative positions of the multiple silencer groups G are not limited to these. Specific examples will be described below.

[0095] 15, the outdoor unit 7 of the present embodiment includes a first compressor 601 and a second compressor 602. The first compressor 601 and the second compressor 602 are arranged side by side in the short side direction of the base plate 10.

[0096] The first compressor 601 and the second compressor 602 are each disposed straddling the first convex portion 31 and the second convex portion 32 of the base plate 10. As shown in Fig. 16, a first silencer group G1 configured in the third convex portion 33 is located between the first convex portion 31 and the second convex portion 32. In addition, in the longitudinal direction of the base plate 10, a fourth convex portion 34 is located on the opposite side of the third convex portion 33 with the second convex portion 32 as the center. A third silencer group G3 having the same configuration as the first silencer group G1 is configured in the fourth convex portion 34.

[0097] That is, the first compressor 601 and the second compressor 602 are each disposed in a position on the base plate 10 overlapping with the first silencer group G1 and outside and adjacent to the third silencer group G3 when viewed from above.

[0098] The second silencer H2 and third silencer H3 (not shown) of the first silencer group G1 are located directly below the first compressor 601. Also, the fifth silencer H5 and sixth silencer H6 (not shown) of the first silencer group G1 are located directly below the second compressor 602. The first silencer H1, fourth silencer H4, and seventh silencer H7 of the first silencer group G1 are located outside the compressor 60 in a plan view.

[0099] In this embodiment, the operation noises from the first compressor 601 and the second compressor 602 are radiated intensively to the second silencer H2, the third silencer H3, the fifth silencer H5, and the sixth silencer H6 of the first silencer group G1 and are attenuated. The operation noises are also radiated to the first silencer H1 to the seventh silencer H7 of the third silencer group G3 and the first silencer H1, the fourth silencer H4, and the seventh silencer H7 of the first silencer group G1 and are attenuated.

[0100] Thus, according to the outdoor unit 7 of the present embodiment, even when two compressors, a first compressor 601 and a second compressor 602, are provided, two silencer groups, a first silencer group G1 and a third silencer group G3, can be provided without being restricted by the space of the base plate 10. Moreover, these two silencer groups, the first silencer group G1 and the third silencer group G3, can attenuate the operating sounds radiated from the first compressor 601 and the second compressor 602, respectively. Therefore, the noise from the outdoor unit 7 can be further reduced.

[0101] Although the embodiment has been described above, the present disclosure is not limited to this, and the following modifications are also possible.

[0102] 3 and 4 show an example of a configuration in which the base plate 10 is the bottom plate of the housing 70, and the partition member 40 is arranged in the groove portion 20 extending linearly on the plate surface of the base plate 10, so that the silencer H is located directly below the compressor 60. However, the position where the silencer H is configured may be any position close to the compressor 60. For example, the base plate 10 may be a plate member of the top plate 70c, the front plate 70d, the rear plate 70e, the right plate 70f, and the left plate 70g other than the bottom plate of the housing 70, and the partition member 40 is arranged in the groove portion 20 extending on the plate surfaces of these plate members, so that the silencer H is located to the side and directly above the compressor 60. In addition, the shape of the groove portion 20 extending on the plate surface of the base plate 10 may be any shape as long as the groove portion 20 can configure the silencer H together with the partition member 40, and may be, for example, an arc shape or a wave shape.

[0103] Moreover, in the first embodiment, the partition member 40 is made of metal. However, the partition member 40 may be made of resin, such as elastomer or sponge. The partition member 40 may have the plate-shaped portion 41 made of resin and the partition portion 42 made of metal. From the viewpoints of improving the rigidity of the base plate 10 and preventing vibration, it is preferable that the partition member 40 be made of metal.

[0104] 5 illustrates an example of a configuration in which the plate-shaped portion 41 of the partition member 40 has a strip-like shape and the partition portion 42 has a plate-like shape. However, the shapes of the plate-shaped portion 41 and the partition portion 42 are arbitrary as long as the space S can be defined when the partition member 40 is placed in the groove portion 20. That is, the plate-shaped portion 41 may be formed in a size and shape that can close the opening of the groove portion 20, and may be a polygon such as an ellipse, an oval, a triangle, or a pentagon. Also, the partition portion 42 may be disposed inside the groove portion 20 and extend in the width direction of the groove portion 20 to partition the inside.

[0105] Moreover, the plate-like portion 41 and the partition portion 42 do not necessarily have to airtightly close the opening and the inside of the groove portion 20 in the strict sense. However, from the viewpoint of the silencer H provided on the base plate 10 by the partition member 40 and the groove portion 20 resonating with the operation noise from the compressor 60 and stably attenuating the operation noise, it is preferable that the plate-like portion 41 and the partition portion 42 airtightly close the opening and the inside of the groove portion 20.

[0106] 4 and 5 show an example of a configuration in which the eight partitions 42, the first partition 421 to the eighth partition 428, have their plate surfaces parallel to each other and extend from the plate-shaped portion 41 in a direction perpendicular to the extension direction of the groove portion 20. However, as long as the space S can be defined with the partition member 40 disposed in the groove portion 20, the direction and number of the partitions 42 extending may be arbitrary. For example, each of the multiple first partitions 421 to the eighth partition 428 may extend from the plate-shaped portion 41 in a direction inclined to the extension direction of the groove portion 20. In addition, there may be at least two partitions 42, one partition 421 and the other partition 422 adjacent to each other.

[0107] FIG. 11 illustrates a configuration in which a plurality of first partition parts 421 to eighth partition parts 428 have three plate-shaped first fixing parts 441 to third fixing parts 443 at their ends for fixing the partition member 40 to the base plate 10. However, the fixing parts 44 are not essential as long as they can fix the partition member 40 to the base plate 10, and the number and shape of the fixing parts 44 are optional. For example, the groove part 20 and the end part of the partition part 42 may be welded, or the partition part 42 may be formed by an elastic member to be slightly larger than the inner width of the groove part 20, and the partition member 40 may be pressed into the inside of the groove part 20 to be fixed by pressure bonding to the base plate 10. In addition, the fixing part 44 may be formed, for example, of a thick plywood, or may be formed of a strip member extending between the adjacent partition parts 421 and 422 and parallel to the plate part. Furthermore, the fixing members for fixing the fixing portion 44 to the base plate 10 are not limited to screws, but may be, for example, rivets, or bolts and nuts.

[0108] 12 illustrates a configuration in which the volumes of the second space S2 and the third space S3 are different in the second silencer H2 and the third silencer H3 having different resonance frequencies, and the second through hole 502 and the third through hole 503 are formed with the same opening area and the same hole length. However, the second silencer H2 and the third silencer H3 may have different resonance frequencies by making the volumes of the second space S2 and the third space S3 the same and changing the opening areas and hole lengths of the second through hole 502 and the third through hole 503. Furthermore, the volumes of the first space S1-seventh space S7 of the first silencer H1-seventh silencer H7 and the opening areas and hole lengths of the first through hole 501-seventh through hole 507 may be changed to have different resonance frequencies.

[0109] 13 illustrates a configuration in which the partition member 40 has a strip-shaped intermediate partition portion 429 extending between the first partition portion 421 to the eighth partition portion 428 and in the extending direction of the groove portion 20. However, the number, shape, and location of the intermediate partition portion 429 are arbitrary. For example, the intermediate partition portion 429 may be formed of a tapered plate having a thickness that varies partially instead of a strip-shaped plate, or may extend diagonally between one partition portion 42 and the other partition portion 42 to partition the space S. Furthermore, two or more intermediate partition portions 429 may be provided in the partition member 40.

[0110] 15 illustrates a configuration in which the compressors 60 housed in the housing 70 are a first compressor 601 and a second compressor 602, and the first compressor 601 and the second compressor 602 are arranged side by side in the short direction of the base plate 10. However, the compressors 60 may be arranged in any number and positions as long as they are arranged in a position close to the partition member 40 of the base plate 10. For example, there may be three compressors 60, and the third compressor 60 may be arranged adjacent to either the first compressor 601 or the second compressor 602 in the long direction of the base plate 10, or the first compressor 601 and the second compressor 602 may be arranged side by side on a diagonal line on the upper surface 10b of the base plate 10.

[0111] 2 illustrates an example of a configuration in which the outdoor unit 7 in which the silencer H is provided on the base plate 10 is an upward-blowing type outdoor unit in which the outdoor blower 71 and the exhaust port 70b are located on the top plate 70c of the housing 70. However, the outdoor unit 7 may be a front-blowing type outdoor unit in which the outdoor blower 71 and the exhaust port 70b are located on the front plate 70d of the housing 70.
