Description

[Detailed Description of the Invention] As is well known, soundproofing sashes have a great effect on soundproofing and airtightness, but because they are airtight, there is little inflow of outside air, which not only contaminates the indoor air but also prevents indoor use of open flames. Therefore, it is inevitable that there will be dangers such as oxygen deficiency. In order to deal with this, conventional ventilation systems have been used in which air intake holes are provided at appropriate positions on the sash (mainly on the upper stile) and the air intake holes are opened and closed by shutter plates to introduce outside air. However, the above-mentioned conventional device does not have a sufficient sound deadening effect and not only impairs the original function of the soundproof sash, but also has the most serious drawback. When used in the kitchen, due to the structure of the kitchen, the ventilation system is in a position almost directly facing the face, and the supplied outside air hits the face directly, so I dislike this during the winter, so I close the shutter and use the atmosphere. There is a risk of causing an oxygen deficiency accident as a result of inappropriate usage.

In view of the above-mentioned conventional drawbacks, the present application has proposed an air supply box that is installed on the indoor side of the intake opening of the upper stile or upper frame.
Two sets of numerous air supply holes are installed at two different locations, one of these two sets of air supply holes can be opened and closed by a shutter plate, and the other set of air supply holes is By keeping the device open at all times, even if it is used inappropriately as described above, the necessary minimum amount of outside air is always supplied, and the outside air that is supplied does not directly hit the face and cause discomfort. In addition, we will muffle the outdoor noise that enters when performing ventilation.
This application relates to a sash with a noise-reducing ventilation device that does not impair the original 411 function of a soundproof sash, and the present application will be described in detail below with reference to drawings showing embodiments.

-1'' is an air supply box attached to the upper stile 3 of the inner shoji 2 of the pull speed sash, and is configured as follows.
As shown in Figure @1, the sides [5, 5' are fixed to the left and right Fii- of the indoor side B of the air intake hole 4 using appropriate means such as screws, and the pivot shafts protrude from the side plate 5.5°. 6, the bottom edge of the base 7 is pivoted, and the edge of the top plate 9 is brought into contact with the protruding piece 10 of the upper column 3.
Screw 11. Connect the upper stile 3 and the side plate 5.5° with the screw 12, and connect the base 7 and the side plate 5.5° with the screw 12 to connect the air supply box 1.
It consists of a box body. Therefore, by centering the screw 12, the base body 7 is opened by swinging around the pivot 6 toward the indoor side B, so that the inside of the air supply box 1 can be easily cleaned.

In addition, in the embodiment of the present application, only the air supply box 1 configured as described above is shown, but this is not limited to the above, and if the structure of the upper stile 3 is different, the air supply box 1 The configuration is also different, and the external shape of the tower body is also different.
It can also be implemented with a polygonal or arcuate box with a cross-sectional shape other than the approximately rectangular shape shown in the drawings. □It doesn't matter what the configuration shape is.

I of air supply box 1! As shown in a developed view in FIG. 5, two sets of air supply holes 13.13° are provided on the IIA surface. In this embodiment, one set of air supply holes 13 is connected to the air supply box 1.
In front of WI8, the other set of air supply holes 13° are exposed to the top plate 9. Therefore, the air supply hole 13° drilled in the top plate 9
Determine the total opening area so that the minimum amount of air necessary for ventilation is supplied.Next, 14 is a shutter plate, and the shutter plate 1 and 4 are provided with a A ventilation hole 1 that communicates with and opens the bored air supply hole 13
5 is protected and slidably polymerized to mis. Therefore, by sliding the shutter plate 14 left and right with the operating grip 16 shown in Figure 1, the air supply hole 13 bored in the front wall 8 is opened and closed, and the air trapped in the top plate 9 is supplied. The hole 13' always remains open.

17. 17'' and 17'' are sound deadening plates, respectively. The sound deadening plate 17 is attached to the shutter plate 14 and slides together with the shutter plate 14, and the sound deadening plate 17'' covers the entire surface of the pore 4. , and a sound deadening plate 176 is installed inside the air supply box 1 so as to cover the air supply hole 13° drilled in the top l1i9. As shown in Fig. 4 and 5v4, there are many through holes 1 on the entire surface.
8 is hollow, but the total area of the through hole 18 is the same as that of the sound deadening plate 17.
17゛, 50% of the area of 17'.

The following is an immediate expansion with an aperture ratio of 50g & below.
A punched plate made of metal or punched metal is used, and the shape of the through hole 18 is not limited to that shown in the drawings.

Next, as shown in FIG. 2, a guide plate 19 is arranged in the air supply 1i1, and bent so as to communicate with the air intake holes 4 and the air supply holes 13, 1B'. An air passage 20 is formed. The guide plate 19 is made by pasting an appropriate sound absorbing material 22 on a core material 21 made of aluminum or the like, bridging the core material 21 between the two 411iIi 5.5', and fixing it to the side plate 5.5' by appropriate means. Install by. In the figure, numeral 23 is a well-known louver for rain and water protection, numeral 24 is an outer shoji screen, and numeral 25 is an upper frame.

The present application is constructed as described above, and the outside air from outside A enters the air supply box 1 through the air intake hole 4 through the through hole 18 at 17 degrees, but when the outside air passes through the through hole 18, it is compressed once. The noise is muffled by diffusing the air again. Noise is reduced by the so-called "resonant silencing effect." Experiments have shown that this silencing effect is most effective when the aperture ratio is 50% or less, and taking into account that the net used for screen doors does not have the above effect, in this application, the aperture ratio is 50% or less as described above.
% or less punched metal, expanded metal, etc. are used. The noise is muffled by the sound-absorbing plate 17' and the air that enters the air supply box 1 has a noise level of g! when it passes through the bent air passage 20 due to the sound-absorbing effect of the sound-absorbing material 22 and the interference effect of the bending path. Furthermore, this outside air is forced to the front wall 8 side,
The sound is silenced again by the sound deadening plate 17.17I attached to the top plate 9, and when the air supply hole 13 on the front wall 8 is open, the air supply between this air supply hole 13 and the top plate 9 is reduced. If the air supply 13 is closed from both the hole 13' and the top plate 9
The air is supplied to the room B only from the air supply hole 13 of the air.

Therefore, in this application, the outside air supplied to room B is silenced again by the sound deadening plates 17. Needless to say, when using the ventilation system of the present application, the air supply hole 13 drilled in the front 1 as shown in FIG. 2 is opened and the air supply hole 13 is opened. 13 and the air supply hole 13° of the top plate 9 for ventilation, it is desirable to introduce the maximum amount of air for ventilation, and the manufacturer also instructs the correct and proper use as described above. However, as mentioned above, users do not like the outside air to directly hit their faces, so they do not like the air supply holes 13 in the front wall 8.
There are many cases where people mistakenly and inappropriately use fire with the vents closed, and in this case, with the conventional "!! gas" system, the ventilation holes are completely closed, leading to accidents such as lack of oxygen. As detailed above, one group has a large number of air supply holes 13, 131 in the front a! 8, and the other group has a large number of air supply holes 13, 131 in the chopsticks 9, respectively. The air supply hole 13 drilled in the WIIa 18 is configured so that the shutter plate 1 is normally in the open position, and the air supply hole 13 of the top plate 9 has an opening of 13 degrees + 1 stack number, so that the minimum amount of air necessary for ventilation is obtained. Even in the case of improper use as mentioned above, the minimum required amount of outside air is always supplied, preventing oxygen deficiency accidents and preventing accidents like this. Since the outside air supplied by the above is blown directly above the air supply hole i3 of the top plate 9, it does not directly hit the occupant's face and cause discomfort, and the user's intention to ventilate is avoided. Regardless of the presence or absence, ventilation is always performed automatically even when the mukura yari is compressed.'' As described above, this application uses the sound deadening plates 17. Not only can noise be effectively reduced to provide comfortable ventilation, but
I punched it in the top plate 9! Since the air supply hole 13° is always open, oxygen deficiency accidents are prevented and the indoor air is not contaminated. Further, by constantly introducing outside air and promoting convection of indoor air, the indoor temperature distribution can be made uniform and effective heating and cooling can be performed.

Note that the present application is not limited to the embodiment described in J, and it is most preferable that the air supply hole 13. It is possible and the choice of wall surface is free.

Also, the sound deadening plates 17, 17', 17'' are designed to mute the sound twice, but they may be muted only once.
The mounting position is not limited to that shown in the drawings, but the purpose can be achieved by installing it along any route that introduces outside air into the room. Also, regarding the installation position of the device of the present application, although the illustrations have only explained the case where it is installed on the upper stile 3 of the inner shoji 2, the installation position can be freely selected depending on the situation, and the installation position can be freely selected depending on the situation. It can be applied to any type of soundproofing sash such as quick, single-pull, and dead-fit.
