Description

Frame of a panel for a silencer, a panel and a silencer including the same {Frame for panel of noise arresting apparatus, panel and noise arresting apparatus having the same}

Embodiments relate to a frame of a panel used in a silencer, a panel including the same, and a silencer, and a frame of a panel used for a silencer that reduces noise in an air-conditioning room with a cooling and heating unit, and a panel and a silencer including the same. will be.

A silencer may be disposed to reduce noise in an air conditioning room in which a cooling/heating device is disposed. The silencer may include a silencer chamber, a silencer louver, a silencer, and a soundproof panel. Such a silencer may be formed by combining panels including a sound absorbing material.

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

The silencer is manufactured through a manufacturing process that cuts, bends, welds, and fastens through bolts the steel plate forming the panel, and finishes with silicon work.

In manufacturing the silencer, cutting, bending, welding, etc. of the steel plate have a great influence on the size and quality of the silencer. When bending an iron plate, since the iron plate is stretched, it should be cut as small as the size of the expanded steel plate in consideration of the size of the expanded iron plate when cutting. However, in each factory that manufactures the silencer, there is a problem in that the size of the steel plate is all different from the length of the steel plate and the size of the steel plate is all different in the steel plate bending device.

In addition, in the case of the frame of the panel, it is attached by welding, but since the welded part is not visible from the outside, it is difficult to check the welding state and it is difficult to secure the quality of the product. Since the exterior and interior of the silencer and even the inner frame are all made of iron plate and glass wool, the larger the size of the silencer, the heavier the weight, so there is a greater risk of safety accidents.

The manufacturing method of the silencer may be any one of the Pittsburgh method, the Jesalggyeoggi method, the Wakgu method, and the Jjolmdae method.

The Pittsburgh method is a top plate to connect the outer plates. Remove the corners of the bottom, front, back, left and right plates, shape the steel plate using a roller, bend it, and prepare for assembly. This Pittsburgh method has the advantage of being easy to connect the outer plate and being strong, and the specifications and size of the silencer product are accurate, but the process is complicated and time-consuming because a lot of welding is required on the inner frame.

Although the jigsaw method has the advantage that it can be easily performed at the time of on-site assembly, it has the disadvantage that it takes a lot of time because it requires a lot of welding to the frame.

The waggu method can shorten the manufacturing time because there is less welding than the Pittsburgh method or the skewing method.

The joldae method requires a lot of frame welding similar to the jesalkeok method, but the parts that are not jesalkeok are cut and bent, so the number of welds can be reduced compared to the jesalkeop. In this method, a U-shaped or L-shaped jolda is used and a welding machine is used. However, the jjoldae method requires a lot of welding anyway, so it takes a lot of manufacturing time, and there is a problem that the quality variance is large for each manufacturer.

Referring to FIG. 14, the first panel 100A has a first mounting space K1 in which a second panel 100B used as the front or rear surface of the silencer 10 is mounted, and the left side of the silencer 10. A second mounting space K2 is provided where the third panel 100C used as the side or right side is mounted.

The second panel 100B is inserted into the first mounting space K1 to form a rear surface of the silencer 10 . The third panel 100C is inserted into the second mounting space K2 to form the left side of the silencer 10. Although not shown in the drawings, the second panel 100B forming the front surface is inserted into the first panel 100A to form the front surface of the silencer 10, and the third panel 100C forming the right side. It is inserted into this first panel 100A to form the right side of the silencer 10.

The first panel 100A and the second panel 100B, and the first panel 100A and the third panel 100C may be coupled through fastening members such as pins.

As such, since the panels 100 are easy to assemble with each other, there is an advantage in that the panels 100 can be easily assembled and combined not only in a manufacturing plant but also in the field.

15 is a diagram illustrating a state in which the frame 110 is connected and expanded.

Referring to FIGS. 3 and 15 , in order to increase the size of the silencer 10, frames 110 may be connected and used. For example, when connecting the third frame 110C to the first frame 110A, the second sidewall 113C of the third frame 110C is attached to the fourth space S4 of the first frame 110A. By inserting it, the second outer wall 116A of the first frame 110A overlaps the second side wall 113C of the second frame 110B. With the first frame 110A and the third frame 110C connected in this way, the second outer wall 116A of the first frame 110A, the first sidewall 112A, and the second outer wall 112A of the third frame 110C. The first frame 110A and the second frame 110B may be coupled through the pin P3 penetrating the side wall 113C and the second inner wall 115C.

16 is a view showing a silencer according to another embodiment, in which the second plate 122 is mounted on the outside of the frame 110 .

Referring to FIG. 16, as a silencer according to another embodiment, the second plate 122 is not inserted into the second space S2 of the frame 110 and is positioned outside the frame 110. The second plate 122 may be coupled to the frame 110 through two pins P2 .

17 is a view showing a panel including a reinforcing member FT for reinforcing between frames 110 as a silencer according to another embodiment.

Referring to FIG. 17, a reinforcing member (FT) in the form of a steel plate is disposed near the corner of the panel 100, that is, at a portion where the frame 110 and the frame 110 are adjacent to each other, across the adjacent frame 110, and The reinforcing member FT may be coupled to the frame 110 through the 4 pins P4. Through the reinforcing member FT, it is possible to prevent the panels 110 from being twisted or moved.

The reinforcing member FT may have a straight line shape or a bent “ㄱ” shape depending on the use.

In the above, a frame for a silencer panel according to one preferred embodiment of the present invention, a panel including the same, and a silencer have been examined in detail with reference to the accompanying drawings.

One embodiment of the present invention described above should be understood as illustrative in all respects and not limiting, and the scope of the present invention will be indicated by the claims to be described later rather than the detailed description above. And it should be construed that all changes or transformable forms derived from the meaning and scope of the claims as well as their equivalent concepts are included in the scope of the present invention.
