Description

[Detailed description of the invention] (Field of industrial application) The present invention is used in an air conditioner to absorb and muffle the sound of the air blown from the air conditioner to the air outlet between the floor wall and the ceiling. This invention relates to an air conditioning outlet sound deadening box installed in a street.

(Prior art) Conventional air-conditioning outlet sound deadening boxes include glued and assembled boxes made of lightweight glass wool boards for sound absorption, but this lightweight box is extremely weak in material strength compared to heavy metal boxes, so it is natural that However, reinforcement from the outside is essential. For example, as shown in Figure 9 of the attached drawings, a complicated iron cage T reinforcing cover is applied to the corners and the entire circumference of the glass wool assembly box b', and each duct E' of the air conditioner and anemo-type outlet is placed on top of that. Due to the weak strength of the box material, it is difficult to attach the corresponding short pipes 5' and 8' to the fitting holes on one side and bottom side of box b' to connect F', respectively. It is difficult to fix the box directly to the wall with screws, etc., and if external pressure, impact, twisting pressure, etc. are generated on each short pipe 5', 8' when fitting and connecting each duct E'F', the box itself may be damaged. Since there is a risk that the short pipes 5',
Since it is essential to have a configuration in which 8' is clamped from the outside, a duct corresponding to each short pipe 5', 8' is required.
When connecting E'F', the angle material becomes a protrusion, and the tip of each duct E'F' does not reach the wall of the contact box, and each short pipe 5', 8' is connected to each duct.
As a result of the inevitable occurrence of a so-called exposed part X where E'F' does not fit, it is also essential to carefully wrap each exposed part X with a heat insulating material to keep it warm.
In order to install the box b' between the floor wall and the ceiling, the hanging rod 10' that is used to hang the box b' from the floor wall is not directly attached to the top plate of the box body, which is susceptible to external pressure, but is instead a separate angle member. As a result of the necessity of mounting via S', (1) the box body requires external reinforcement, and the intervening attachment of a complicated iron cage T and angle member SS' results in a complex overall configuration, a large number of parts, and a large number of manufacturing man-hours. Therefore, the cost is very high, and it is also heavy, making manufacturing, handling, transportation, and construction extremely inconvenient and uneconomical.

(2) Since the exposed portion X requires time-consuming heat insulation work, it is uneconomical, and together with the increase in parts, the manufacturing and construction costs become extremely high.

(3) When installing an appropriate ventilation adjustment shutter mechanism independently in the box, the external reinforcement of the iron cage T becomes an obstacle, making installation difficult and further increasing costs.

(4) The appearance of the box is very poor due to the complicated external reinforcement.

There are many drawbacks such as:

(Problems to be solved by the invention) The present invention aims to easily and reliably eliminate all of the drawbacks of the conventional products mentioned above, and includes a single die rib frame installed vertically in the center of the box. This completely eliminates the need for conventional complicated, cumbersome, unsightly, and heavy external reinforcement, and also allows each short pipe and hanging rod to be fixedly attached, completely eliminating any external force hindrance to the assembly box. It greatly simplifies the man-hours required for manufacturing the box, and the lightweight box significantly saves labor in handling, transporting, and installing the box.
In addition, we aim to provide a highly economical product with a simple box design, extremely low product cost, easy construction, low cost mass production, and high demand. .

(Means for Solving the Problems) The present invention incorporates a molded rib frame into the assembly box made of glass wool, which has weak strength, thereby ensuring reliable reinforcement of the box.
The frame is characterized by being used as a fixing device for short pipes and hanging rods,
The embodiments of the present invention will be described below with reference to the accompanying drawings.

One side plate 1 has a fitting hole 6 into which one of the short pipes 5 having a flange edge 4 which fits and connects the air duct E' of the air conditioner E is fitted, and the bottom plate 2 has an anemo-type fitting hole 6 to be fitted outside the ceiling H. A hanging rod 10 for fixing to the floor wall G is provided in the top plate 3 with a fitting hole 9 into which the other short pipe 8 having the flange edge 7 which fits and connects the blow-off duct F' of the blow-off outlet F is fitted.
A glass wool assembly box B is assembled to the box body by gluing the glass wool assembly plates with holes 11 into which the lower part of the glass wool assembly board is inserted. 12 and 12' are left open at the lower side, and an insertion hole is inserted into one side of the center part of the upper side, through which the threaded part 13 at the lower part of the hanging rod 10 is inserted, and the nut 14 is secured to the protruding threaded part 13. A metal mold rib frame 1 in which a collar 15 is installed vertically so as to communicate with a fitting hole 11 of a top plate 3.
6, one of the short tubes 5 is fixedly attached to the front surface of the frame 16 by welding 17 or screwing the flange edge 4 that contacts the front surface with the front surface vertically splitting the center of the cylinder. , and both corners 1 of the bottom side
2, 12', the other short tube 8 is
The flange edges 7 in contact with the bottom surfaces of both corners 12, 12' are fixedly attached by welding 18 or screws so that the lower opening crosses the center of the cylinder, and each of the short pipes 5, 8 is connected to the side. The frame 16 is fixedly attached to the bottom side of the box b, and the short pipes 5 and 8 are fitted into the corresponding fitting holes 6 and 9, so that the frame 16 is shaped like a rib at the center of the box. Then, the threaded part 13 of the hanging rod 10 is passed through the fitting hole 11 of the top plate 3 through the insertion collar 15 on the upper side of the frame 16, and the nut 14 is secured to the protruding threaded part 13. It is something to do.

The shape of the mold rib frame 16 is not limited to the B shape in which both sides are upright, and the shape of the rib frame 16 as shown in FIG. By using the bent legs, it is convenient and advantageous to install the ventilation adjustment shutter mechanism inside the box.

Alternatively, a frame made of a thin U-shaped pressed plate may be used, and the hanging rod 10 can be attached to the upper side of the frame 16 by using the collar 15 or by providing a screw hole on the upper side and directly screwing it. A mechanism or other suitable attachment means may be employed.

(Function) Since the present invention is constructed as described above, the short pipes 5 and 8 are fixedly attached to the sides and the bottom of the opening at the center of the interior of the glass wool assembly box b, which is assembled by adhesive using the glass wool assembly plate. A metal molded rib frame 16 of a size that is in contact with the inner peripheral wall of the box is built in and has an insertion collar 15 for the hanging rod 10 attached to the upper side.
However, simply by fitting the short pipes 5 and 8 into the corresponding fitting holes 6 and 9 of the one side plate and the bottom plate 2 and assembling the box by gluing, a rib is formed inside the box. is sufficiently reinforced by the presence of the frame 16 without external reinforcement. Also, short pipes 5 and 8
Since it is fixedly attached to the frame 16, the external pressure or twisting pressure generated by the duct connection does not directly affect the box b, so the safety of the assembled box is guaranteed.

Also, the hanging rod 10 can be installed using the fitting hole 11 of the top plate 3.
By fitting the insertion collar 15 of the frame 16 through the frame 16, no external force is applied to the assembly box, so the box B can omit the conventional complicated and troublesome external reinforcement. If the frame 16 is to be installed on a wall, the frame 16 can be hung by adjusting the length of the hanging rod 10 attached to the frame 16 and attaching the upper end of the rod 10 to the floor wall G. Accordingly, the box surrounding the frame 16 can be hung without using an angle connector, and hanging construction can be easily carried out. The fitting connection of the duct E'F' to each of the short pipes 5 and 8 is achieved by simply passing the short pipes 5 and 8 through the fitting holes 6 and 9, and since there are no obstructions around them, the duct E'F' is connected until it reaches the box wall. Because it is possible to completely mate the
The appearance of exposed parts due to conventional incomplete fitting does not occur, and heat insulation work is omitted. Therefore, by connecting the ducts to each of the short pipes 5 and 8, the sound of the air from the air conditioner E is reliably absorbed and muffled in the box b made of glass wool from the air duct E', and the sound is muffled and transferred to the air duct F. ' to the outlet F.

(Effects) As a result of the above, the present product can be assembled into a main body product by gluing and assembling the assembly box by passing the fitting holes 6 and 9 through the short pipes 5 and 8 attached to the frame 16, centering on one square-shaped rib frame 16. can be easily and quickly assembled and manufactured, and since the frame 16 serves as a reinforcing bone, no external reinforcement is required at all, and the reinforced safety of the box b is reliably guaranteed without external reinforcement. The product value improves due to the simple appearance.

In addition, since only one frame 16, assembly box, short pipes 5, 8, and hanging rod 10 mechanism are required, the cost is extremely low and it is extremely lightweight compared to conventional products. Therefore, the handling, transportation, and installation work are extremely convenient and labor-saving, and it can be mass-produced at low cost, making it extremely economical and highly demanded. 5,8
Since the installation of the hanging rod 10 and the assembly of the box body are all performed, all of the above-mentioned drawbacks of the conventional method are eliminated, and the duct connection to the short pipes 5 and 8 is completely fitted, so there is no need for extra heat insulation work. Since there is no exterior structure, it is convenient to be able to easily equip the ventilation adjustment shutter mechanism, and the external force during construction does not affect the assembled box, so the frame 1
Coupled with the presence of the 6 ribs, the safety of the box body and the ease and safety of construction are guaranteed, and the overall mechanism is extremely simplified, and together with the small number of parts, the manufacturing man-hours can be greatly simplified. It has the advantage of being economical, convenient to provide, etc.
