Description

  The present invention relates to a soundproof package that covers and mounts noise sources to reduce noise that leaks from the noise sources.

  In the field of industrial machines such as compressors, it is generally to surround the machine body with a soundproof package (housing for soundproofing) to prevent the diffusion of noise generated from the machine body such as a compressor. It has been done. On the other hand, the soundproof package is provided with a door or lid for the convenience of the assembly work and maintenance work of the machine body, and often there is a gap around the door or lid circumference and the soundproof package main body. Performance degradation is a problem. The cause of such a gap is mainly the instability of the method of fixing the door or lid, the step around the door or the step around the lid, and the like.

  JP-A-2012-122424 (Patent Document 1) is directed to a soundproof cover in which a seal member is sandwiched between the periphery of a door and the periphery of a lid and the soundproof package main body. Disclosed is a mounting structure. The mounting structure of the soundproof cover is a mounting structure of a soundproof cover mounted so as to cover the noise source with a seal member interposed between the outer peripheral edge portion and the noise source, wherein the soundproof cover is pressed against the noise source The soundproof cover may be attached to the noise source by compressing the seal member. As a result, it is possible to reduce the sound leaking to the outside from the gap between the end of the soundproof cover and the other part.

JP, 2012-122424, A

  However, in the soundproof cover mounting structure disclosed in Patent Document 1, when using fixing means such as fastening with bolts, the degree of closure between the periphery of the door or the periphery of the lid and the soundproof package body may vary. . For this reason, the degree of adhesion between the seal member and the main body side receiving portion and the degree of compression of the seal member (if the degree of compression is small, noise may sometimes pass through the seal member) are not stable, and the sound insulation effect becomes unstable. In addition, with this soundproof cover mounting structure, not only the fit of the position of the door or the position of the lid is not stable, but if the degree of closing is increased to increase the degree of compression, the degree of closing is too strong and the door or cover is deformed Noise may be transmitted rather than the gap.

  The present invention has been made in view of the above-mentioned problems, and provides a soundproof package capable of reliably reducing noise leakage by sealing the gap stably regardless of the degree of closure. With the goal.

In order to solve the above-mentioned subject, the soundproof package concerning the present invention has taken the following technical measures.
That is, the soundproof package according to the present invention comprises a main body having an opening and a noise source housed inside, a door closing the opening, and a position corresponding to the periphery of the opening, the main body or the door A soundproof package having a sealing member provided in the housing, the thickness of the sealing member being kept smaller than the thickness in the open state when the opening is closed by the door It is characterized by having an interval maintaining means.

Preferably, the space maintaining means can be configured to maintain a constant space along the periphery of the door.
More preferably, the space maintaining means can be configured to maintain the space by providing a portion where the door and the main body abut against each other.
More preferably, the space maintaining means can be configured to be formed by at least one of the folded back of the periphery of the door and the projection on the main body side.

More preferably, the folding may be configured to be folded twice or more, and the first folding angle may be about 90 degrees, and the second and subsequent folding angles may be about 90 degrees or more.
More preferably, the folded back may be folded back twice so that the first folded angle is about 90 degrees or more and the second folded angle is about 90 degrees with respect to the door.

More preferably, the door closing the opening is a door which can be opened and closed with one side as a rotation center, and the space maintaining means pivotally supports the door pivotally, and the door And a contact portion that contacts the main body in the closed state and restricts rotation of the door.
More preferably, the contact portion may be provided on the other side of the door and on the side opposite to the side on which the pivot shaft is provided.

More preferably, the seal member may be provided on the inner wall side of the opening provided in the main body.
More preferably, when the door is in a closed state, the seal member may be compressed toward the inner wall of the opening.
The most preferable other mode of the soundproof package according to the present invention is a main body having an opening, in which a noise source is housed, a door closing the opening, and a position corresponding to the periphery of the opening. In the soundproof package including the main body or the sealing member provided on the door, when the opening is closed by the door, the thickness of the sealing member is kept thinner than the thickness in the open state. And the space maintaining means covers the side surface of the seal member when the door is in the closed state.

  By using the soundproof package according to the present invention, noise leakage can be reliably reduced by sealing the gap stably regardless of the degree of closure.

Hereinafter, a soundproof package according to an embodiment of the present invention will be described in detail based on the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description about them will not be repeated.
First Embodiment
FIG. 1 is a perspective view showing the entire structure of a packaged compressor, which is an example of an industrial machine, including the soundproof package 1 according to the present embodiment, and FIG. FIG. 1B is a view in which the opening 14 is opened by the door 20 and the door 30. FIG. In the open state shown in FIG. 1 (B), the compressor is assembled and the compressor is maintained, and the compressor is operated in the closed state shown in FIG. 1 (A). The number of doors is not limited to two as long as there is at least one door. Further, the application of the soundproof package according to the present application is not limited to the compressor shown as the embodiment.

  The soundproof package 1 includes a main body having an opening 14 and a noise source (here, a compressor) housed therein, a flat door 20 and a door 30 for closing the opening 14, a periphery of the door 20 and a door 30. A seal member 22 and a seal member 32 provided on the inner surface on the periphery thereof. In addition, not a door may be a lid, a door or a lid may be provided, and the opening direction may be an upper direction or another direction. In the present embodiment, such a door, a lid and the like are described as a door, but the door in the present application is meant to include the lid and the like.

  The frame 10 of the main body is provided with screw holes 12 for closing a door 20 and a door 30 to be described later and the main body. Through the through holes (not shown) provided around the door 20 and the door 30 from the surface on the outer side of the soundproof package 1, screwing members 40 (for example, screws, bolts, etc.) are formed in these screw holes 12. And the door 30 and the body 30 are closed.

  The positions of the screw holes 12 and the positions of the through holes (no reference numerals) correspond to each other, and the flexible seal members 22 and 32 are provided corresponding to the positions. The screwing member 40 penetrates the seal member 22 and the seal member 32 to compress the seal member 22 and the seal member 32 and is screwed into the screw hole 12. The members for closing the door 20 and the door 30 and the main body are not limited to the screwing member 40, and a set of magnets that attract each other even if it is a combination of a tapered receiver and a hook ( In practice, the door and the body are often made of metal, and in such a case, only one magnet may be used.

The seal member 22 and the seal member 32 are preferably made of a material having flexibility and compressibility, and in particular, a material having an excellent sound absorbing property such as a urethane foam material is more preferable.
The soundproof package 1 is a space maintaining means for maintaining the thickness of the seal member 22 and the seal member 32 thinner than the thickness of the open state when the opening portion 14 is closed by the door 20 and the door 30. It is characterized by having. The interval maintaining means will be described in detail below.

  FIG. 2 is a cross-sectional view showing a detailed structure of the soundproof package 1 according to the present embodiment. In FIG. 2, the state (FIG. 2 (A), FIG. 2 (B)) and the state (FIG. 2 (C)) immediately before changing the door 20 from the open state to the closed state in FIG. It is the figure seen from. The door 20 is closed in the direction of the white arrow. For this reason, in FIG. 2, the code | symbol corresponding to the door 20 is attached | subjected, and the code | symbol corresponding to the door 30 is described in parentheses. 2 (A) shows the seal member 22 (32) attached to the door 20 (30), while FIG. 2 (B) shows the seal member 22 (32) attached to the frame 10 of the main body. It differs in that it is attached. Thus, the seal member may be provided at any position.

  The folded back portion 24 (34) shown in FIG. 2 implements the above-mentioned interval maintaining means. The folded portion 24 (34) is formed by turning back the edge of the door 20 (30) by approximately 90 degrees. Then, as shown in FIG. 2C, when the door 20 (30) is closed, the folded back portion 24 (34) is a folded back portion of the door 20 (30) as shown as part A. 24 (34) and the frame 10 of the main body abut, and the distance between the door 20 (30) and the main body in the closed state is determined and maintained. A state in which the thickness t (2) of the seal member 22 (32) in the closed state is thinner than the thickness t (1) in the open state is maintained. In other words, the flexible sealing member 22 (32) is compressed until it becomes an interval at which the folded-back portion 24 (34), which is the space maintaining means, abuts on the frame 10 of the main body (t (1) > T (2)) is maintained. In the present application, to abut on the main body is meant to include abut on the frame 10 of the main body which is one of the components of the main body.

  In this manner, the flexible sealing member 22 (32) is compressed and closely attached to the frame 10 of the main body, whereby the gap between the frame 10 of the main body and the door or lid can be completely filled by a step or the like. Therefore, the deterioration of the sound insulation performance can be prevented. Further, since the tip of the folded portion 24 (34) abuts on the frame 10 of the main body, the closed state by the fixing means (here, the screw or bolt which is the screwing member 40) is stable, and as a result, the sound insulation is stable. You can get the effect.

Next, the detailed structure of the soundproof package according to the modification of the present embodiment will be described with reference to FIGS. 3 (A) to 3 (D). The same components as those described above in FIGS. 3A to 3D are denoted by the same reference numerals, and the detailed description thereof will not be repeated.
FIGS. 3A to 3D are cross-sectional views showing the detailed structure of the soundproof package according to the present modification. Similarly to FIG. 2, FIG. 3 also shows the state (FIG. 3A, FIG. 3B, FIG. 3C) and the closed state immediately before the door 20 is closed from the open state in FIG. It is the figure which looked at the state (FIG. 3 (D)) from upper direction. Close the door 50 in the direction of the white arrow. In FIG. 3 (A), the seal member 52 is attached to the door 50, while in FIG. 3 (B) and FIG. 3 (C), the seal member 52 is attached to the frame 10 of the main body. The difference is that Furthermore, the shape of the seal member 52 is different between FIG. 3 (B) and FIG. 3 (C). As in FIG. 2, the seal member may be provided at any position in this way, provided that the thickness of the seal member 52 in the closed state is maintained smaller than the thickness in the open state. Is not particularly limited.

  The double folded back portion 54 and the folded back portion 56 shown in FIGS. 3A to 3D realize the above-described interval maintaining means. The folded back portion 54 is formed by turning back the periphery of the door 50 once by approximately 90 degrees, and the folded back portion 56 further folds the folded back portion 54 by approximately 90 degrees or more (FIG. 3A to FIG. 3D) In this case, it is formed by folding back at approximately 135 degrees. Note that the folding may be further repeated.

  Then, as shown in FIG. 3 (D), when the door 50 is closed, the folded portions 54 and 56 are folded at the folded portion 54 and the folded portion in the door 50 as shown by the B portion. The top formed by 56 and the frame 10 of the main body abut each other, and the distance between the door 50 and the main body in the closed state is determined and maintained. A state in which the thickness t (4) of the seal member 52 in the closed state is thinner than the thickness t (3) in the open state is maintained. That is, the flexible sealing member 52 is compressed until the folded portion 54 and the folded portion 56, which are the space maintaining means, reach an interval at which the folded portion 54 and the folded portion 56 come into contact with the frame 10 of the main body. (4) is maintained. As described above, in the present application, to abut on the main body also means to abut on the frame 10 of the main body which is one of the components of the main body.

  In this manner, the flexible seal member 52 is compressed to be in close contact with the frame 10 of the main body, thereby completely filling the gap between the frame 10 of the main body and the door or lid due to a step or the like as in FIG. As a result, the sound insulation performance can be prevented from deteriorating. In addition, since the tip of the apex formed by the folded back portion 54 and the folded back portion 56 abuts on the frame 10 of the main body, the closed state by the fixing means (here, screw or bolt which is the screwing member 40) is stable As a result, a stable sound insulation effect can be obtained. Furthermore, in addition to the case of FIG. 2, the rigidity around the door 50 is improved, and deformation of the door 50 can be suppressed, and a more stable sound insulation effect can be obtained.

  Furthermore, another double-folded portion will be described with reference to FIGS. 3 (E) to 3 (H). Fig. 3 (E) is Fig. 3 (A), Fig. 3 (F) is Fig. 3 (B), Fig. 3 (G) is Fig. 3 (C), and Fig. 3 (H) is Fig. 3 (D). Correspond to each. Also, the door 50 is the door 60, the seal member 52 is the seal member 62, the folded portion 54 and the folded portion 56 are the folded portion 64 and the folded portion 66, and the thickness t (3) is the thickness t (5) (4) corresponds to the thickness t (6), and the B part corresponds to the C part.

  The double folded back portion 64 and the folded back portion 66 shown in FIG. 3 (E) to FIG. 3 (H) implement the above-mentioned interval maintaining means. The folded back portion 64 is formed by turning back the periphery of the door 60 by approximately 90 degrees or more (approximately 135 degrees in FIG. 3), and the folded back portion 66 sets the folded back portion 64 at approximately 90 degrees with respect to the door It is formed by further turning back so as to abut.

  As shown in FIGS. 3E to 3H, even in the case where the space maintaining means is realized by the double folded back portion 64 and the folded back portion 66, as shown in FIGS. 3A to 3D. Similarly to the case where the space maintaining means is realized by the double folded back portion 54 and the folded back portion 56, deterioration of the sound insulation performance can be prevented, and a stable sound insulation effect can be obtained, and further, In addition to the above, the rigidity of the periphery of the door 60 is improved, and deformation of the door 60 can be suppressed, and a more stable sound insulation effect can be obtained.

  The sound insulation characteristic of such a soundproof package 1 will be described with reference to FIG. FIG. 4 shows the measurement results of the noise level at a distance of 1500 mm and a height of 1000 mm from the door 20 and the door 30 of the soundproof package 1. "After countermeasure" is a compressor provided with the soundproof package 1 according to the present embodiment, and "before countermeasure" is a compressor provided with a conventional general-purpose soundproof package. It can be easily understood from FIG. 4 that the soundproofing characteristics are improved in the entire frequency range.

As described above, according to the soundproof package according to the present embodiment, the soft seal member is compressed to be in close contact with the frame of the main body, thereby forming a gap between the frame of the main body and the door or lid due to a step or the like. Since it can be completely filled in, it is possible to prevent the deterioration of the sound insulation performance. In particular, since the tip end of the folded portion abuts on the frame of the main body, the closing state by the fixing means (here, the screw or bolt which is the screwing member 40) is stable, and as a result, a stable sound insulation effect is obtained. it can.
Second Embodiment
Next, with reference to FIGS. 5A and 5B, a second embodiment of the soundproof package according to the present invention will be described.

The door 20 to the door 30 in the first embodiment include the lid disposed so as to cover the opening 14. However, the door 20 to the door 30 in the second embodiment (hereinafter, representatively, the left side The door 30 that closes the opening 14 is intended to be an “open door” that can be opened and closed with the one side as a rotation center.
In the case of the second embodiment, the space maintaining means provided on the door 30, which is an open door, abuts against the pivot shaft 42 for rotatably supporting the door 30, and the frame 10 of the main body in the closed state of the door 30 And a contact portion 41 that regulates the rotation of the door 30.

  For example, like the door 30 shown in FIG. 1A, the door 30 of the second embodiment has a rectangular shape in a front view. A pivot shaft 42 facing vertically is disposed on the left side edge of the door 30 (the edge located on the left side of the soundproof package 1 in a front view), and the door 30 is directed to the left by the pivot shaft 42 It is pivotally supported to rotate. The door 30 is pivoted about the pivot shaft 42 to open the opening 14 (see FIG. 1B).

In the present specification, the device is described using directions (front-back direction, left-right direction, up-down direction) when the soundproof package 1 shown in FIG. 1 is viewed from the front, but this is for convenience of explanation. And the configuration is not limited.
5A and 5B disclose a structure in which the door 30 is sectioned in the horizontal plane.
As shown in FIGS. 5A and 5B, the left side edge of the door 30, that is, the rotation base end portion is a bent portion 43 in which a flat member of the door 30 is bent to form a box or bent structure. The pivot shaft 42 is disposed in the bent portion 43, while the contact portion 41 constituting the space maintaining means is provided on the right side edge of the door 30. The bent portion 43 may be hollow inside or may have a solid, solid structure. The contact portion 41 is provided on the side opposite to the side on which the pivot shaft 42 of the door 30 is provided.

The contact portion 41 has substantially the same structure as that of the first embodiment, and includes a folded portion 34 formed on the right side edge of the door 30. The folded portion 34 is formed by turning back the right edge, the upper edge, and the lower edge of the door 30 by approximately 90 degrees. The seal member 32 is attached to the inside of the folded portion 34.
Then, as shown in FIG. 5B, when the door 30 is closed, the folded portion 34 of the door 30 and the frame 10 of the main body abut each other, and the distance between the door 30 and main body in the closed state is determined. Be maintained. A state in which the thickness t (2) of the seal member 32 in the closed state is thinner than the thickness t (1) in the open state is maintained. In other words, the flexible sealing member 32 is compressed until the folded portion 34, which is the space maintaining means, comes into contact with the frame 10 of the main body, thereby thinning the state (t (1)> t (2)) Is maintained.

  Furthermore, the seal member 32 is disposed also on the left inner wall of the opening 14 and in the portion covered by the bent portion 43 of the door 30. As shown in FIG. 5B, as the door 30 approaches the closed state, the bending portion 43 approaches the opening 14 and the seal member 32 attached to the inner wall of the opening 14 is moved in the depth direction of the opening 14 ( It is compressed in the direction along the longitudinal direction to improve air tightness and soundproofness. Even in this case, the thickness t (2) of the seal member 32 in the closed state is thinner than the thickness t (1) in the open state by the space maintaining means constituted by the contact portion 41 and the pivot shaft 42. Is maintained.

  In this case, as shown in FIG. 7, the lining portion 44 is formed in a projecting shape from the inner wall of the opening portion 14 so as to face the center of the opening portion 14. It is good to keep the rear side along the depth direction. By so doing, the seal member 32 can be reliably compressed without being displaced rearward, and air tightness and soundproofness can be surely enhanced.

  In summary, the space around the pivot shaft 42 of the door 30 is small, and the relative movement between the frame 10 of the main body and the pivot base end portion of the door 30 is complicated and the rotation component is large. Therefore, as in the first embodiment, it is difficult to provide the folded back portion 34 (the contact portion 41) in the vicinity of the pivot shaft 42. Therefore, in the second embodiment, the contact portion 41 is provided at a portion separated from the rotation shaft 42, and is used as a space maintaining means. Similarly, the seal member 32 is provided on the side surface of the frame 10 not facing the pivot shaft 42 of the door 30.

The modification of the soundproof package 1 which concerns on 2nd Embodiment, ie, the door 30, is shown by FIG. As shown in FIG. 6, on the rear surface (the side facing the opening 14) of the bending portion 43 provided on the rotation base end side of the door 30, a protrusion 45 having an acute angle toward the opening 14 is provided. It is formed. Due to the presence of the projection 45, when the door 30 is closed and the bent portion 43 of the door 30 approaches the opening 14, the projection 45 bites into the sealing member 32, thereby opening the sealing member 32 into the opening 14. It strongly compresses in the depth direction (front and back direction), and further improves the air tightness and soundproofness.
Third Embodiment
Next, a third embodiment of the soundproof package according to the present invention will be described.

The soundproof package 1 in the third embodiment, that is, the door 30 has substantially the same configuration as the door 30 in the second embodiment, but differs in the following points.
That is, as shown to FIG. 8A and FIG. 8B, the door 30 in 3rd Embodiment is an open door, Comprising: The bending part 43 does not exist in the rotation base end side. Further, the pivot base end (left side edge) of the door 30 and the frame 10 of the main body are connected by the hinge fitting 46 including the pivot shaft 42, and the door 30 can be pivotably opened and closed relative to the main body I have to. In addition, the seal member 32 is disposed on the rear side of the door 30 and on the left side edge.

On the other hand, the frame 10 of the main body on which the pivoting base end of the door 30 is pivotally supported is notched in an L shape in cross sectional view, and the hinge fitting 46 is disposed in the notch. There is. Further, a part of the notch is a protrusion 47 that protrudes from the main body side toward the center of the opening 14.
As shown in FIG. 8B, in the closed state of the door 30, the seal attached to the rear surface of the door 30 is achieved by the pivoting base end portion of the door 30 approaching the projecting portion 47 formed on the frame 10 of the main body. The member 32 is compressed in the depth direction by the gap between the door 30 and the projection 47, and the air tightness and soundproofness are enhanced.

In order to exert such an effect, in the closed state of the door 30, the distance between the door 30 and the projecting portion 47 needs to be set smaller than the thickness t (1) of the seal member 32 in the opened state of the door 30. There is.
Fourth Embodiment
Next, a fourth embodiment of the soundproof package according to the present invention will be described.

As shown to FIG. 9A, the door 30 in 4th Embodiment has the bending part 43 in a rotation base end like the door 30 of 2nd Embodiment. The second embodiment is also the same as the second embodiment in that the seal member 32 is disposed on the left inner wall of the opening 14 and in the portion covered by the bent portion 43 of the door 30.
However, as a different point, the rear side of the bent portion 43 of the door 30 is formed to be erected toward the back, and may be referred to as a projecting portion 48.

  As shown in FIG. 9B, in the closed state of the door 30, as the projecting portion 48 approaches the frame 10 of the main body, the seal member 32 attached to the inner wall portion of the opening 14 moves in the width direction. Compressed, which increases the air tightness and soundproofness. In order to produce such effects, in the closed state of the door 30, the distance between the projecting portion 48 of the door 30 and the frame 10 of the main body is greater than the thickness t (1) of the seal member 32 in the open state of the door 30. It needs to be set small. In the case of the present embodiment, since the affixing surface of the seal member 32 and the compression direction are orthogonal to each other, the seal member 32 does not escape and sealing can be performed more reliably.

In this case, as shown in FIG. 10, it is better to provide a portion formed in a projecting shape so as to face the central portion of the opening 14 from the inner wall of the opening 14.
When the door 30 is closed, the projecting portion 48 of the door 30 abuts on the portion formed in a projecting shape, so that the sealing member 32 does not become thinner than a predetermined thickness. That is, the portion formed in a projecting shape from the inner wall of the opening 14 to face the central portion of the opening 14 constitutes the contact portion 41 of the space maintaining means.

Although the seal member 32 is provided on the left inner wall of the opening 14 in the above-described embodiment, the seal member 32 may be provided on the projecting portion 48 of the door 30.
It should be understood that the embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is indicated not by the above description but by the claims, and is intended to include all the modifications within the meaning and scope equivalent to the claims.

  For example, the space maintaining means may be formed by a protrusion provided on the main body side and in contact with the door 30 instead of or in addition to the folded back of the peripheral edge of the door 30. Further, the tip or apex of the folded portion 34 does not necessarily have to abut on the flat portion of the door 30. Furthermore, the spacing maintaining means may be configured to maintain a constant spacing along a portion of the periphery of the door 30 rather than the entire periphery.
