Description

[Detailed description of the invention] Industrial application field The present invention relates to a simple partition, and more specifically, a simple partition that has a built-in suction device for air, etc. inside the partition and can exhaust indoor air, etc. Pertains to.

BACKGROUND ART Conventionally, as a simple partition used for a room partition or the like, for example, as shown in the cross-sectional view of FIG. 3, there is one constructed of a core material 20, a sound absorbing layer 21, and a surface layer 22. This core material 20 serves as a skeleton that maintains the external shape of the partition, and is formed from an iron plate or wood. The sound-absorbing layer 21 is made of a sound-absorbing material such as an air layer or a glass wool layer, and may have a symmetrical structure around the core material 20 as shown in FIG. 3, or may have a one-sided structure (not shown). There is something I did. The surface layer 22 is the outermost layer, and is made of a thin steel plate or a resin board when the inside is an air layer, and is made of woven fabric or panting metal when the inside is filled with glass wool or the like.

Partitions loaded with such sound-absorbing materials are called sound-absorbing types.

In recent years, a large number of office equipment have been installed in offices, etc., and the noise generated by them, voices from conversations, cigarette smoke, etc. have a negative impact on the human body, so there is a demand for a more comfortable office space. As a result, there has been a demand for partitions with sound absorption and exhaust functions.

However, in such conventional partitions, since a thin steel plate or a resin board is used for the surface layer, the partitions naturally do not have air permeability. On the other hand, in the case of sound-absorbing types that are filled with glass wool, the glass wool itself is not necessarily made of long fibers, but also contains short fibers of several microns, so such sound-absorbing types have poor breathability. However, continuous ventilation can cause microscopic glass wool to enter human lungs and cause lung cancer. In other words, conventional partitions do not have ventilation, or ventilation is not possible due to health reasons, so there is no need for a structure that eliminates cigarette smoke through the partition. I can't say it. In particular, in recent years, smoking has become publicly recognized as causing a nuisance to others, and it is well known that non-smoking rooms are now provided in trains, cafeterias, etc.

In summary, as mentioned above, in the past, sound-absorbing type partitions have been developed, but no partitions that can eliminate indoor air, such as cigarette smoke, have been proposed at all. do not have.

Problems to be solved by the invention This invention aims to solve the above problems, and specifically aims to propose a simple partition that can suck in and exhaust indoor air, cigarette smoke, etc. .

Means for Solving the Problems and Their Effects That is, the present invention is a partition made of a sound absorbing plate in which at least one surface layer is made of a porous A plate having continuous holes, and the partition has a It is characterized in that it has a built-in suction device, and the end of the exhaust pipe of this suction device is provided to communicate with the outdoors.

Hereinafter, the present invention will be explained based on the drawings.

1 and 2 are longitudinal cross-sectional views showing one embodiment of a partition according to the present invention, and FIG. 3 is a longitudinal cross-sectional view showing an example of a conventional partition.

1 is a sound absorbing plate, 2 is a support frame, 2A is an insertion slot,
3a and 3b are rice cakes, 5 is an iron plate, 10 is a casing,
11 is a fixture, 12 is a bracket, 15 is a motor, 16 is a fan, 18 is an exhaust pipe, 19 is a connecting ring, 20 is a core material, 21 is a sound absorbing layer, 22 is a woven fabric,
30 is a smoke purification device, and 35 is an exhaust louver.

First, the partition shown in FIG. 1 is a box-shaped three-dimensional structure with a square cross section in which a sound absorbing plate 1 and an iron plate 5 are arranged parallel to each other.A support frame 2 is provided along the inside of the iron plate 5. Beams 3a and 3b are provided at an appropriate interval between the support frame 2 and the sound absorbing plate 1 to provide an appropriate space.
It is constructed of a casing 10 having an opening at an appropriate position between and 3b, and a suction device disposed in this casing 10.

The sound-absorbing plate 1 is made of a porous material such as A porous material having continuous holes, and it is essential that the sound-absorbing plate 1 has continuous holes, so that the air inside and outside the partition can be conducted. Noise, ie, air vibration, is attenuated by such porous parts and converted into frictional energy, resulting in sound absorption. The reason for selecting the sound absorbing material is that it is light in weight, is easy to handle, can be easily screwed or bonded to the beam 3, and is relatively inexpensive. Further, such an A porous material can be easily produced by pressureless sintering of A powder having a particle size of preferably 100 μm to 300 μm in a non-oxidizing atmosphere at a temperature just below the melting point of the A powder.

Further, the iron plate 5 is, for example, a colored iron plate or one whose surface is coated with various paints or metals, but in addition to these iron plates 5, it may also be a resin board or the like.Furthermore, a woven cloth may be further added to improve the appearance design. It may also improve sex. The main components of the suction device include a fan 16 connected to a motor 15 and an exhaust pipe 18.
The motor 15 is fixed to the casing 10 by a blanket 12, and the casing 10 is fixed to the beam 3 by a fixture 11.
An air exhaust pipe 18 is connected to the opening of the connecting ring 19.
It is configured to be connected by. With this configuration, the rotation of the motor 15 causes the suction fan 16 to operate in conjunction with the rotation of the motor 15, and the air outside the partition due to rotational suction of the fan 16 is efficiently guided to the exhaust pipe 18.

Note that the method of installing the suction device inside the partition is not limited to this, and other methods other than those described above may be used, as long as the structure efficiently exhausts smoke from outside the partition into the inside. .

Note that even if the surface of the porous material A of the sound absorbing board 1 shown in FIG. can. Therefore, even if these skin materials are used as the outermost layer for aesthetic reasons, it is essentially a partition with a surface structure of porous A plate. This includes whatever was used.

Next, the effect will be explained.

The air and cigarette smoke outside the partition are quickly removed from the casing 1 by turning on the power for rotating the motor (not shown), which causes the motor 15 and the fan 16 to rotate.
It is introduced within the region bounded by 0. Due to the continued suction air pressure, the introduced air and cigarette smoke are concentrated at the end of the casing and the exhaust pipe 18
will be discharged to In order to minimize pressure loss, the exhaust pipe 18 preferably has an inner diameter of 10 m/m or more, and is made of, for example, a tube made of vinyl chloride. The exhaust pipe 18 is vented to the atmosphere through a duct or directly outdoors through an indoor location that is as inconspicuous as possible, such as inside the partition or on the ceiling or under the floor.

In the partition according to another embodiment of the present invention shown in FIG. 2, an exhaust louver 35 is attached to a part of the sound absorption board 1 made of the porous A sound absorption board shown in FIG. 1, and a smoke purification device 30 is attached to the exhaust pipe 18. The structure is designed to improve exhaust efficiency. For example, porous A in FIG.
Plate 1 is made of a material with a high porosity (porosity) of about 30 to 70%, but in order to further reduce air flow resistance, some of the porous A plates are used at the expense of some sound absorption performance. An exhaust louver 35 is used. This exhaust louver is preferably a variable louver, closed when not in use, and opened when in use. The smoke purification device 30 is disposed in the middle of the exhaust pipe 18 and is configured to purify smoke, and this smoke purification device 30 is loaded with an adsorption material such as water-wet felt or activated carbon with a large specific surface area inside. However, it is designed to actively absorb resin. Note that felt is preferable as the adsorption material because it can be washed with water and reused. In addition, an insertion port 2A is provided in the support frame 2 on the back side of the partition, and the structure is such that the purifier 30 or the felt inside the purifier can be taken out and replaced from the insertion port 2A. , it is preferable to use a lid similar to the color iron plate 5 and keep it closed at all times.

With the above configuration, air containing cigarette smoke and the like inside the room can be efficiently exhausted to the outside.

The structure and effects of the embodiment of the partition according to the present invention have been described above, but the partition according to the present invention may be any structure as long as it is equipped with a suction device or a suction device and a purification device. Regarding its shape, size, etc., for example, the entire wall surface from the floor to the ceiling may be movable or fixed and assembled and used,
A so-called screen type may also be used, and all of these have the effects described in the embodiments.

<Effects of the invention> As explained in detail above, the present invention provides a porous material A in which at least one surface layer has continuous pores.
A partition made of a sound absorbing plate made of a board, characterized in that a suction device is built inside the partition, and the end of an exhaust pipe of the suction device is provided to communicate with the outdoors. .

Therefore, a porous A plate having continuous holes is constructed as a sound absorbing material on the surface of the partition, a suction device or a suction device and a smoke purification device are built inside the partition, and the smoke is exhausted outdoors through an exhaust pipe. As a result, it is possible to efficiently exhaust indoor air or cigarette smoke.
