Description

Frame for panel of noise arresting apparatus, panel and noise arresting apparatus having the same}

The embodiment relates to a panel frame used in a silencer, a panel including the same, and a silencer, and relates to a panel frame used in a silencer that reduces noise in an air-conditioned room with an air-conditioning device, a panel including the same, and a silencer. will be.

A silencer may be placed to reduce noise in an air-conditioned room where an air conditioning or heating device is installed. The silencer may include a noise chamber, a noise louver, a silencer, and a soundproof panel. This silencer can be made by combining panels containing sound-absorbing materials.

The panel may include a frame, a steel plate coupled to the frame, and sound-absorbing material. As an example of a silencer, in the case of a silencer, panels forming a hexahedron may be combined with each other to form a space therein.

Silencers are manufactured through a manufacturing process that involves cutting, bending, welding, and bolting the steel plates that form the panel, and finishing with silicone work.

In manufacturing a silencer, cutting, bending, and welding steel plates have a significant impact on the size and quality of the silencer. When bending a steel plate, the steel plate stretches, so it must be cut as small as the stretched size, taking into account the size of the steel plate that stretches when cutting. However, there is a problem that in each factory that manufactures silencers, in the devices that bend steel plates, the dimensions to which the steel plates are stretched are different, and the sizes to which the steel plates are cut are all different.

Additionally, in the case of the panel frame, it is attached by welding, but since the welded area is not visible from the outside, it is difficult to check the welding condition, making it difficult to ensure the quality of the product. Since the exterior and interior of the silencer, as well as the inner frame, are all made of steel plates and glass wool, the larger the size of the silencer, the heavier it is, increasing the risk of safety accidents.

The manufacturing method of the silencer can be one of the Pittsburgh method, Jesalkeogi method, Wakgoo method, and Jjoldae method.

The Pittsburgh method uses a top plate to connect the exterior plate. Prepare for assembly by cutting off the corners of the bottom plate, front plate, back plate, left plate, and right plate, and bending and bending the steel plate into shape using a roller. This Pittsburgh method has the advantage of being easy and strong to connect the outer plate and producing accurate specifications and sizes of the silencer product, but it has the disadvantage of being a complicated process and requiring a lot of time because it requires a lot of welding on the internal frame.

The splitting method has the advantage of being easy to assemble on site, but it has the disadvantage of taking a lot of time because it requires a lot of welding on the frame.

The waxing method can shorten the manufacturing time because it requires less welding than the Pittsburgh method or the splitting method. However, in the case of on-site assembly, it is not preferred because it must be joined with long screws of 75 mm, but it has the advantage of a faster manufacturing process.

The Jjoldae method requires a lot of frame welding, similar to the jjoldae method, but by cutting and bending parts that are not used as jjoldae, the number of welds can be reduced compared to the jjoldae method. This jjoldae method uses U-shaped jjoldae or L-shaped jjoldae and uses a welding machine. However, since the jjoldae method requires a lot of welding, it takes a lot of manufacturing time, and there is a problem in that there is a large difference in quality between manufacturers.

Meanwhile, the entrance direction of the first space S1, the entrance direction of the second space S2, and the entrance direction of the third space S3 are in one direction, and the entrance direction of the fourth space S4 is one direction. The direction on one side is opposite to the direction on the other side.

The plate 120 may include a first plate 121, a second plate 122, and a third plate 123.

The first plate 121 is a steel plate and can be inserted into the first space S1. The second plate 122 may be disposed in the second space S2. The second plate 122 may be a perforated plate including a plurality of holes 122a.

The third plate 123 is disposed in the fourth space S4 and may be a steel plate having a bent area with an “L” shaped cross section.

Figure 4 is a diagram showing two frames 110 facing each other, and Figure 5 shows the process of manufacturing the plate 120 and the panel 100, and shows the process of mounting the first plate 121 to the frame 110. This is a drawing.

One side of the first plate 121 is inserted into the first space S1 of one of the two frames 110A and 110B, and the other side of the first plate 121 is inserted into the two frames (110A, 110B). By being inserted into the first space S1 of the other frame 110B among 110A and 110B, the first plate 121 may be formed to form one side of the panel 100.

Since the first space (S1) or the second space (S2) is formed consistently through extrusion processing, the thickness of the first plate 121 or the second plate 122 can be kept constant. In particular, the thickness of the first plate 121 or the second plate 122 can be maintained constant. In the case of the first plate 121 and the second plate 122, there is no bending area, so there is no need to bend the first plate 121 or the second plate 122, and there is no change in thickness due to bending. , constant quality of the silencer 10 can be secured.

Figure 6 is a diagram showing the process of manufacturing the panel 100 and the process of mounting the third plate 123 to the frame 110.

Referring to FIGS. 3 and 6, the panel 100 constituting the silencer 10 is positioned (e.g., the third plate 123 is placed in the fourth space S4 according to the upper and lower plates of the silencer). The third plate 123 is a steel plate with an “L” shaped cross section, and one side of the third plate 123 can be inserted into the fourth space S4.

Figure 7 is a diagram illustrating the process of manufacturing the panel 100, in which the sound absorbing material 130 and the second plate 122 are mounted on the frame 110.

Referring to FIGS. 3 and 7 , after the first plate 121 or the third plate 123 is mounted, the sound-absorbing material 130 is mounted in the third space S3 of the two frames 110. After the sound-absorbing material 130 is mounted on the third space S3, one side of the second plate 122 is connected to the second space S2 of one of the two frames 110A and 110B. is inserted into, and the other side of the second plate 122 is inserted into the second space (S2) of the other frame 110B of the two frames 110A and 110B, so that the second plate 122 is panel ( 100) can be formed to achieve different aspects.

A plurality of holes 122a may be formed in the second plate 122. Since the first plate 121 has no bending area like the second plate 122, there is an advantage that there is no need to bend the second plate 122.

With the first plate 121 disposed in the first space S1 and the third plate 123 disposed in the fourth space S4, the first plate 121 and the third plate 123 ), the first side wall 112, and the second outer wall 116 are in an overlapped state. Through the first pin P1 that penetrates the second outer wall 116, the third plate 123, the first side wall 112, the first plate 121, and the first inner wall 114 in that order, the first plate (121) and the third plate 123 can be coupled to the frame 110.

Additionally, when the second plate 122 is disposed in the second space S2, the second side wall 113 and the second inner wall 115 overlap. The second plate 122 can be coupled to the frame 110 through the second pin P2 that penetrates the second side wall 113 and the second inner wall 115 in that order.

In this way, since welding is not used to couple the plate 120 to the frame 110, the manufacturing process is simplified and the manufacturing time is greatly reduced. In addition, since the panel 120 can be standardized, there is an advantage that the panel 100 and the silencer 10 including it can be manufactured with uniform quality at any manufacturing plant.
