Description

  The present invention relates to a decoration device installed indoors.

  An interior decoration apparatus related to the present invention is described in, for example, Patent Document 1 below. The apparatus described in the document 1 is based on the same inventor as the present invention, and the present invention is an improvement of the same.

As shown in FIGS. 14A to 14C, the decoration device 1X described in Patent Literature 1 delivers a plurality of overhead lines 140 by connecting ends to the upper frame 120 and the lower frame 130, respectively. While the decorative liquid A flows down in the shape of a polka dot B along the overhead line 140, the polka dot B is irradiated with light from the projector 150. The liquid reservoir 122 provided immediately below the upper frame 120 has a plurality of small holes 124 through which the decorative liquid A and the overhead wire 140 are passed through the bottom 122a. The decorative liquid A passes through the small hole 124 of the liquid reservoir 122, flows down as a polka dot B along the overhead wire 140, and reaches the liquid receiver 132 provided below the lower frame 130. The decorative liquid A that has entered the liquid receiving tray 132 is supplied again to the upper liquid storing tray 122 by a pipe 160 that connects the liquid receiving tray 132 and the liquid storing tray 122 and a pump 162 that is connected to the pipe 160.
As the decorative liquid A of Patent Document 1, a liquid having a viscosity higher than that of water, such as an acrylamide aqueous solution, is used so that the polka dots B are easily formed. Since the indoor liquid dust and the like are adsorbed by the decorative liquid A, such an apparatus has some air cleaning function.
The decoration device 1X is generally configured such that the upper frame 120 is at a height close to the ceiling, and is installed indoors, such as in a store or a hotel entrance.

Japanese Patent Publication No. 48-33235

In the decoration device 1X described above, each of the overhead lines 140 is attached to the upper frame 120 and the lower frame 130. That is, by connecting the upper end portion of each overhead line 140 to the upper frame 120 and the lower end portion to the lower frame 130, the plurality of overhead lines 140 are handed up and down.
However, the operation of connecting one end of each overhead line 140 to the upper and lower frame 120 or 130 is complicated. Further, if the overhead wire 140 is cut or loosened while the operation of the device 1X that has been assembled is continued, the worker goes up to the ceiling or the like each time, and the overhead wire 140 is stretched one by one. It was also necessary to repair and adjust the rack.
In addition, when the ends of the overhead wires 140 are connected to the frame frames 120 and 130, the loose wires tend to be unevenly loosened. That is, since it is difficult to make the way of knots and the positions thereof identical for each overhead line 140, the tension tends to be different for each overhead line 140. When the difference in tension between the overhead wires 140 is large, loose overhead wires 140 and overly strong overhead wires 140 are mixed, and as a result, repair and adjustment are often required after assembly is completed.

Furthermore, when it becomes necessary to move the apparatus, disassembling and reassembling the assembly once has been a very laborious operation.
In addition, the acrylic amide aqueous solution used as a decoration liquid has a disadvantage in that the water evaporates and the viscosity increases when used for a long time, and it becomes difficult to flow down into a polka dot, or the solvent is precipitated and a part of the icicle is connected to the overhead line 140. Also occurred.
In addition, if an observer or a passerby touches the overhead wire or the decoration liquid of the apparatus, the overhead line may be repelled and the decoration liquid may be scattered.

  The present invention has been made in consideration of the above points, and an object of the present invention is to facilitate the work of transferring a plurality of overhead wires up and down and subsequent maintenance, and to easily suppress variations in the tension of the overhead wires. It is another object of the present invention to provide an interior decoration device that can easily move the device and can use the liquid for a long period of time.

The interior decoration device of the invention is provided with a plurality of small holes at the bottom of a liquid reservoir provided at the top, and a wire is passed through each small hole and is handed up and down, and from the small hole to the wire It is an interior decoration device in which the liquid falls as droplets along, and the upper part of the delivered wire is inserted and attached to the small hole at the bottom of the liquid storage dish from below It is characterized by.
If the upper part of the delivered wire is inserted and attached to the small hole in the bottom of the liquid storage dish from below, the worker goes up to the ceiling or the like to install the wire. This eliminates the need to do this, which is advantageous in terms of work efficiency and safety.

The interior decoration device with an air purifying function of the present invention has a plurality of small holes provided at the bottom of a liquid reservoir provided at the top, and the dust adsorbing liquid (decoration liquid) descending from the small holes Drops in the form of droplets along a plurality of wires (overhead wires) passed up and down between the liquid reservoir plate and the liquid receiving plate provided at the lower part (in many cases, these droplets are dropped from the attached projector. To which light is applied)
A wire clamp that has a flow path extending vertically and that allows the liquid in the liquid reservoir dish to flow downward from the flow path and that can clamp the vicinity of the upper end portion of the wire is provided in the liquid reservoir. It is characterized in that it is inserted from below into the small hole at the bottom of the dish and is detachably attached.
In this upholstery device, for example, as shown in FIG. 2, the upper end of each wire 4 is inserted and fixed together with the wire fastener (bolt 24) from below into the small hole 22c of the upper reservoir 22. It is what.

The interior decoration device with an air purifying function configured as described above can be used to fasten the wire to the liquid storage pan at the top if the vicinity of the upper end of the wire is fastened to the wire fastener. From below, it can be easily performed by simply inserting the wire rod fastener into the small hole in the bottom of the reservoir pan. Since the wire clamp is detachably attached to the small hole, when maintenance is required, such as repair or replacement of the wire after assembly, remove it from the bottom of the liquid reservoir dish, repair or replace the wire, Thereafter, it can be conveniently inserted into the small hole again from below and attached.
If the upper part of the wire can be attached to the liquid storage dish from below, it is not necessary to fasten the wire above the liquid storage dish as in the example of FIG. That is, it is not necessary for the worker to go up to the ceiling or the like and perform the work.

  The wire rod fastener has a hollow bolt-like component (for example, reference numeral 24 in FIG. 3) that has the flow path on the inside and is inserted into the small hole from below and screwed to the bottom of the liquid reservoir. The wire is passed through the flow path, and is fastened to the wire clamp by hanging a retaining member attached near the upper end to the upper end of the flow path. It is good to be.

  In this way, if the wire rod fastener is a hollow bolt-shaped part, it can be easily attached by simply screwing it into the bottom of the liquid reservoir dish. When removing, it is only necessary to turn the screw in the opposite direction, so no special tool is required. It can be attached and removed any number of times. In addition, it is necessary to pass the wire in advance through the flow path inside the wire fastener, but the wire rod is also fastened to the wire fastener by using the above-described retaining member. It is possible to use a hard wire that is difficult to bend and hard to be tied.

  The interior decoration apparatus with an air purifying function of the present invention has the above-described liquid reservoir tray and liquid receiving tray (including the wire material handed over to them, the wire material fastener and the retaining member), for example, as shown in FIG. It is good to be assembled on a frame having

  Since such an interior decoration device with an air cleaning function has wheels, the device can be easily moved together with the frame. Therefore, it can be installed in any room and used for air purification and decoration in the room.

  In the interior decoration device with an air purifying function of the invention, a sealed storage tank is connected to a liquid supply path for supplying the liquid reaching the lower liquid receiving tray to the upper liquid storage dish, and the storage tank However, it is preferable that the liquid inlet side and the outlet side have pipe joints that can be connected to and disconnected from the liquid supply path and that are automatically opened and closed during the connection and separation. In the example of FIG. 8, reference numeral 15 is a storage tank, and reference numeral 16 is a pipe joint (coupler).

  Such an interior decoration device with an air cleaning function can easily exchange a contaminated liquid. That is, it is only necessary to separate the original storage tank containing the old liquid and connect the storage tank containing the new liquid by the pipe joint. The automatic opening and closing action of the pipe joint prevents liquid from leaking during the separation and connection. In order to minimize dripping, it is preferable to use a two-way open / close type pipe joint that closes both the storage tank side and the liquid supply path side when separated.

  Further, the liquid reservoir dish is supported on the upper portion by a plurality of support columns, and any of the support columns is a hollow tubular shape and forms a part of the liquid supply path, and any of the other support columns It is preferably a hollow tube and used in the return pipe for the liquid overflow.

  According to such an interior decoration device with an air cleaning function, it is not necessary to provide a separate dedicated pipe as the liquid supply path, so that the device can be configured to be compact and aesthetic.

In the interior decoration device with an air cleaning function of the invention, the lower end portion of the wire is connected to an attachment member provided above the liquid tray,
The mounting member is formed with mounting holes through which the wires are passed, and
A metal cylinder (for example, attached to an electric wire terminal) in which a body portion having a size that cannot pass through the attachment hole is compressed and deformed so that the wire portion passed through the attachment hole is sandwiched between the wire rods. It may be connected to the mounting member by a crimp terminal.
For example, as shown in the lower part of FIG. 2, crimp terminals 35 for electric wires are crimped and attached to both ends of the wire rod 4, and this is connected to the above-described metal cylinder by hanging it in the lower mounting hole 34 a. It is possible.

According to such an interior decoration device with an air cleaning function, the lower end portion of the wire is passed through the lower mounting hole as described above without forming a knot, and the metal cylinder is applied while applying a predetermined tension to the wire. It can be connected to the mounting member of the device simply by fastening with. Compared with the case of making a knot, there are advantages that the wire can be easily attached to the attachment member and that the tension of each wire is easily set to be substantially uniform.
As the mounting member, for example, a punched perforated plate may be used. This is because the punched perforated plate has a large number of holes and is suitable for attaching each end of a plurality of wires. It is also convenient that it is commercially available and easy to obtain.

  The wire can be partially or wholly increased in distance and area where the liquid flows down, such as spiral, zigzag, zigzag folded, ball chain, net-like, strip-like (wide wire like ribbon). It is also preferable to have a shape. With regard to providing such a shape in part, the upper end to the lower end of the wire may be integrally formed, or a wire such as a spiral may be prepared separately, and a tube may be attached to a part of the straight wire. You may connect using a sleeve, a small connection metal fittings, such as an eggplant, and a crimp terminal.

  When the wire has such a shape in part or in whole, the liquid flowing area (total extension) increases, so that the liquid (droplet) comes into contact with more air. As a result, the air cleaning function can be enhanced. In addition, the decorativeness of the apparatus is enhanced by a spiral shape or the like.

  The wire has a belt-like part in part or in whole, and a plurality of grooves extending in the vertical direction are formed on the wide surface of the belt-like part, and the wide surface It is preferable that the direction of the band-shaped portion is determined so as to include a direction that is not parallel to the air flow. 5 and 6 show an example of such a configuration.

Since the plurality of grooves are formed on the wide surface of the belt-like portion as described above, the liquid is not biased to a part of the wide surface, but easily spreads over the entire wide surface. Thus, the liquid comes into contact with air over a larger area. In order to make the liquid easily spread on the wide surface, in addition to forming the plurality of grooves as described above, fine irregularities may be formed or a hydrophilic surface may be formed.
In addition, wide surfaces include those that are not parallel to the air flow in the room (such as those that are at a right angle or those that are at 45 °). It hits from the direction near the front. Therefore, there is an advantage that the liquid flowing on the surface easily adsorbs dust.
As described above, the interior decoration device having such a configuration has a high air cleaning function.

As the above-mentioned wire, a transparent wire, a colored wire, a wire having reflectivity, or a wire having conductivity or conductivity and having an LED sphere connected thereto may be used. All of the plurality of wires may be the same type of wire, or two or more types of wires may be combined. Moreover, you may combine the wire from which a color differs.
With such an interior decoration device with an air cleaning function, the decorativeness is further enhanced.

  In the interior decoration device with an air purifying function of the present invention, it is preferable that a coil spring is further connected between the attachment member and the wire rod in the lower part. FIG. 4 shows an example.

  When using a hard wire with less stretchability, it is difficult to connect the wire to the mounting member so that the tension of multiple wires is almost uniform, but if it is connected via a coil spring in this way, each wire Since the tension variation of each can be absorbed by the expansion and contraction of the coil spring, the tension of each wire can be stretched almost evenly without adjusting one by one. Moreover, since tension | tensile_strength is easy to maintain, it can prevent that a wire rod sags and contacts an adjacent wire rod.

More preferably, the attachment member to which the lower end of the wire is connected is provided so that the set height can be changed.
By changing the height of the attachment member, the tension state of each wire can be adjusted appropriately by changing the tension state of the wire. If the ends of multiple wires are connected to a single mounting member, the tension state of the multiple wires can be adjusted at once by changing the height of the mounting member. It is possible to adjust the condition quickly and evenly.

In the interior decoration apparatus with an air purifying function of the invention, it is preferable that a plurality of protective barrier wires arranged so as to surround the wire material and not drop the droplets are handed over in the vertical direction.
With such an interior decoration device with an air cleaning function, it is possible to prevent surrounding people or objects from touching the descending liquid droplets or accidentally pulling and cutting the wire. Moreover, as compared with the case of surrounding with an acrylic board or the like, it is surrounded by a thin thread, so that the aesthetic appearance is not impaired and the cost is advantageous.

The distance between the barrier wires is preferably 1.0 cm to 3.0 cm.
If it is this space | interval, it will be easy to see a droplet, the aesthetics of an apparatus will not be impaired, and also a droplet and a wire can be protected from a surrounding person or thing.

  In the interior decoration device with an air cleaning function of the invention, the liquid is preferably mainly composed of polyhydric alcohol (or a derivative thereof) (over 50% of the whole).

Examples of such liquids include ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, polypropylene glycol, trimethylene glycol, 1,3-butanediol, and 1,4-butanediol. 1,5-pentanediol, 3,4-hexylene glycol, octylene glycol, glycerin, alkanediol, and derivatives of the above solvents, and combinations thereof.
According to such an interior decoration device, since the liquid is a polyhydric alcohol, the liquid has an appropriate viscosity, and droplets are easily formed. In addition, since the polyhydric alcohol hardly evaporates or changes in quality, the same liquid can be used for a long time without replenishment or replacement. Furthermore, polyhydric alcohol has antibacterial properties and is used as a preservative in cosmetics and the like (see, for example, JP 2010-180150 A). Therefore, it can be said that the use of polyhydric alcohol as a decorative liquid is very preferable for indoor decoration and air purification.

The liquid may be a mixture of triethylene glycol with polyethylene glycol and water.
When this decoration apparatus is continuously operated using a certain mixed liquid containing water, the mixed liquid gradually changes in quality and often has a strange odor. However, as a result of continuing the test operation over a long period of time using a liquid obtained by mixing the above-described triethylene glycol, polyethylene glycol, and water at a predetermined ratio, the mixed liquid was not altered.
Such an interior decoration device with an air purifying function has the above-described effects, and the flash point of the liquid (droplet) is increased, so that safety is improved. Therefore, it is most preferable for the interior decoration apparatus to use such a mixed liquid among the polyhydric alcohols described above.

More preferably, the liquid further contains an alkanediol.
Alkanediol is a kind of alcohol and has a strong sterilizing power. Therefore, by using a liquid containing alkanediol, it is possible to provide a preferred interior decoration device for air cleaning.

  In the interior decoration device with an air purifying function of the invention, it is preferable that a blower for circulating the indoor air so as to contact the surfaces of the plurality of wires and the liquid droplets descending along the wires is attached. Note that the blower need not be dedicated to the interior decoration device of the invention, and an air conditioner or the like already installed in the room may be used as long as the room air is circulated as described above.

According to such an interior decoration device, indoor air can be actively brought into contact with the droplets by the blower. Therefore, many particles of any size, such as dust, cigarette smoke, and bacteria contained in the air, are adsorbed by the droplets, and as a result, the indoor air is effectively cleaned. Such an interior decoration device is preferably installed in a portion having good air cleaning efficiency in the living area regardless of the height or width of the space while also serving as a decoration.
When the above liquid is a polyhydric alcohol or a derivative thereof, it does not change even when used for a long period of time and has antibacterial properties, so that it is an interior decoration device that is extremely advantageous for air purification. Since polyhydric alcohols have a hydrophilic hydroxyl group attached to a hydrophobic alkyl group, it is possible to adsorb both hydrophobic particles and hydrophilic particles, and perform efficient adsorption and capture. Is considered possible.
For air purification, it is advantageous that the upholstery device is tall and extends from the floor surface to the vicinity of the ceiling. In that case, the air suction port (or the discharge port) by the blower is such that the air flow formed by the blower contacts the entire area of the long wire (and the droplets on the surface) of the tall device as evenly as possible. It is efficient to disperse and arrange in the upper and lower positions.
This system is a system that adsorbs and captures particulate matter by slowly transferring viscous liquid to the wire in the form of droplets, so that a small amount of circulating fluid is sufficient despite a large adsorption area, and operating costs are low. I'm sorry. Specifically, the amount of circulating fluid required to flow down to one wire is about 20 cc / min. For example, even if a device with 1000 wires stretched is operated, a small liquid feed of only 20 liters / min. It is economical because it can be a pump and consumes little power.

It is further preferable to provide a filter with a deodorizing material (for example, activated carbon) in the air flow passage by the blower. As the filter, a high-density clean room filter may be used.
The smoke such as tobacco is adsorbed by the liquid and removed from the air, but the odor of the liquid adsorbing the smoke can be removed by the deodorizing material. Since there is a filter, deodorization and dust collection can be further performed, and the air cleaning function is further enhanced.

A humidifier may be provided at the outlet of the blower.
If the air dries too much, it may hurt your throat, reduce your skin's defenses, and make you more susceptible to infections. If it has, humidity can be kept appropriate, and as a result, the indoor environment can be made favorable. It is also preferable to adjust the humidity using a humidity sensor.

The interior decoration device according to the present invention is provided with a plurality of small holes at the bottom of a liquid reservoir provided at the top, and a wire (overhead wire) is passed through each small hole, and the small hole is passed up and down. The liquid (decoration liquid) descends as droplets along the wire (in many cases, light is applied to the droplets from the attached projector). The part may be fixed at the lower part, and the middle part of each wire may be passed over the two small holes in the upper liquid storage dish.
For example, as shown in FIG. 11, a single continuous wire 4 is passed through two small holes 24d in the upper part of the apparatus and folded, and both ends of each wire 4 are fixed to a lower mounting member 34 or the like. It is good to be.

If it has become above, one continuous wire will be used as two parallel overhead wires in this interior decoration device, and there are the following advantages. That is, a) the number of wires used is halved, and the work of connecting the wires can be reduced by half. b) Since one wire is used approximately twice as long as the conventional wire, even if the fixing position at the bottom (the position of the knot of the wire, etc.) varies as before, it will occur in the wire. The tension variation (deviation) is about half. c) If the wire can be hung from the position of the upper reservoir pan, both ends of each wire can easily reach the lower part.
In addition, since it is not necessary to tie the wire at the top, even if it is not possible to hang the wire easily from the top, if you devise how to pass the wire through the small hole, only from the position below the reservoir pan Wires can be easily attached. For example, a thread ring (threaded thread) is inserted from the bottom of one small hole of the liquid reservoir plate (preferably transparent) into the thread ring, and the other small hole is inserted into the thread ring. After passing through one end of the wire inserted from the top to the top, the thread is pulled back from the original small hole together with the wire so that the wire is folded back over the two small holes. (See FIGS. 12 (a) to 12 (c)), and both end portions of the wire can be hung downward from the liquid reservoir. In this way, the wire rod can be passed over the two small holes of the reservoir pan only by work from below the reservoir pan. Can be installed efficiently and safely. The same merit is obtained when a new wire is attached or when the wire is replaced by maintenance.

In the upholstery device, each end portion of the wire is fixed to a lower mounting member, and the mounting member has a mounting hole through which the wire passes, and the mounting hole The front part of the passed wire is attached by a metal cylinder (for example, a crimp terminal attached to an electric wire terminal) in which a body portion having a size that cannot pass through the attachment hole is compressed and deformed. It is particularly preferable that it is fixed to the member.
For example, as shown in the lower part of FIG. 11, when crimping terminals 35 for electric wires are crimped and attached to both ends of the wire rod 4, and this is used as the above-mentioned metal cylinder body, it is hung and fixed to the lower mounting hole 34 a. Good.

According to such an upholstery device, both ends of the wire do not tie a knot, just pass through the lower mounting hole as described above, and simply fasten with the metal cylinder while applying a predetermined tension to the wire. It can be fixed to the mounting member of the device. Compared with the case of making a knot, it is easy to set the tension of each wire to be substantially uniform, and there is an advantage that the wire can be easily attached to the attachment member.
As the mounting member, for example, a punched perforated plate may be used. This is because the punched perforated plate has a large number of holes and is suitable for attaching each end of a plurality of wires. It is also convenient that it is commercially available and easy to obtain.

  More preferably, the attachment member for fixing each end of the wire is provided so that the set height can be changed.

  In that case, by changing the height of the attachment member, the tension state of each wire can be appropriately adjusted by changing the tension state of the wire. If the ends of multiple wires are fixed to a single mounting member, the tension state of the multiple wires can be adjusted at once by changing the height of the mounting member. It is possible to adjust the condition quickly and evenly.

It is further advantageous that the upper end portion of the small hole is formed with a smooth curved surface having no edges or burrs. FIGS. 10A and 10C illustrate such small holes.
When the upper end portion of the small hole is formed smoothly in this way, the possibility that the wire is cut due to friction with the small hole or the like is reduced even when tension is applied to the passed wire.

  The lower end portion of the small hole may be provided with a protruding portion that protrudes downward from the bottom surface of the bottom of the reservoir pan. For example, it is preferable to use it as shown in FIGS.

In the conventional upholstery device, the lower surface 122b of the liquid reservoir 122 is flat as shown in FIGS. 14 (a) and 14 (c), so that the decorative liquid A that has passed through the small holes 124 is applied to the lower surface 122b of the bottom 122a. In some cases, it travels in the horizontal direction and does not descend along the overhead line 140.
However, in the upholstery device in which the protruding portion is provided on the liquid reservoir as described above, the liquid (droplet) can be reliably lowered along the wire. Since the bottom of the small hole through which the liquid for droplets passes is provided with a protruding part that protrudes downward from the bottom bottom surface of the reservoir pan, it is difficult for the liquid to propagate laterally on the bottom bottom surface of the reservoir pan. is there.

  The small hole is an inner surface of a nozzle cylinder inserted into an opening provided so as to vertically penetrate the bottom of the liquid reservoir dish, and the nozzle cylinder has a lower end portion as the protruding portion of the liquid reservoir dish. It is more preferable if it is fixed in a state of protruding from the bottom lower surface.

  In such an upholstery device, the above-mentioned small hole is formed only by providing an opening at the bottom of the liquid reservoir dish having a flat bottom surface and driving a nozzle cylinder into the opening. No special mold or processing machine is required as means for forming a liquid storage dish having a lower end portion of the small hole protruding downward. Therefore, it is easy to manufacture and the manufacturing cost can be reduced, and it is not difficult to provide an arbitrary number of small holes at arbitrary positions on the bottom of the liquid reservoir dish, and the arrangement of the wire rods can be varied.

  The nozzle cylinder is a blind rivet of a type that buckles the sleeve by applying an external force closer to the seat at the lower end of the sleeve to a metal ball provided on the upper end of the sleeve, and in each blind rivet, It is also preferable that the liquid (droplet) and the wire are passed through the sleeve in a state where the metal ball is removed after buckling.

In such an interior decoration apparatus, a commercially available blind rivet can be used as the nozzle cylinder. This eliminates the need for custom-made nozzle stock or stock keeping, and can be purchased immediately as needed. The above-mentioned blind rivet is inexpensive and can be quickly installed in the opening of the sump dish by simply tightening with a riveter. Moreover, it can be firmly fixed to the opening so that no liquid leaks from between the blind rivet and the opening. Inside the sleeve of the blind rivet that has been buckled to remove the metal ball, there is a small hole suitable for passing the wire.
A seat portion projecting downward is formed at the lower end portion of the sleeve, and this becomes the projecting portion, so that it is difficult for liquid to be transmitted laterally on the bottom surface of the bottom portion of the reservoir pan. In addition, since the inside of the opening is covered with the sleeve whose upper end portion is spread and smoothed by contact with the metal ball, the upper end portion of the small hole has no edge or burr. Therefore, it is possible to prevent the wire rod from being caught or damaged by the edges and burrs during the operation of passing the wire rod through the sleeve (small hole) and then strongly tensioning the wire rod, or during operation after completion. .
It should be noted that eyelets (also referred to as grommets or eyemets) may be inserted and fixed in the small holes of the liquid storage dish instead of blind rivets. This is because even when the eyelet is provided, the upper end portion of the small hole becomes smooth and the protruding portion is formed at the lower end portion.

  In the interior decoration device of the invention, the liquid is preferably mainly composed of polyhydric alcohol (or a derivative thereof) (over 50% of the total).

Examples of such liquids include ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, polypropylene glycol, trimethylene glycol, 1,3-butanediol, and 1,4-butanediol. 1,5-pentanediol, 3,4-hexylene glycol, octylene glycol, glycerin, alkanediol, and derivatives of the above solvents, and combinations thereof.
According to such an interior decoration device, as described above, there are advantages that droplets are easily formed and the same liquid can be used for a long time.

More preferably, the liquid is a mixture of polyethylene glycol and water in triethylene glycol.
This also has the advantage that, as described above, the liquid is hardly changed in quality, and the flash point is increased to improve the safety.

The liquid may be triethyl phosphate or silicon oil.
Such a liquid also has a suitable viscosity and easily forms droplets, and is difficult to evaporate or change in quality, so that it can be used for a long time without replenishment or replacement. Therefore, it can be set as a preferable interior decoration apparatus for interior decoration and air cleaning (described later).

  The interior decoration device according to the present invention may be provided with a blower for circulating indoor air so as to contact the surface of the plurality of wires and the liquid droplets descending along the wires. Note that the blower need not be dedicated to the interior decoration device of the invention, and an air conditioner or the like already installed in the room may be used as long as the room air is circulated as described above.

Even in such an interior decoration device, the air in the room can be brought into active contact with the droplets by the blower. Therefore, many particles of any size, such as dust, cigarette smoke, and bacteria contained in the air, are adsorbed by the droplets, and as a result, the indoor air is effectively cleaned. Such an interior decoration device can be freely installed in a portion having the highest air cleaning efficiency in the living area regardless of the height or width of the space while also serving as a decoration.
If the above liquid is a polyhydric alcohol or derivative thereof, it will not change even when used for a long time, it will not smell even when smoked from tobacco, and it has antibacterial properties. It becomes a decoration device. Since polyhydric alcohols have a hydrophilic hydroxyl group attached to a hydrophobic alkyl group, it is possible to adsorb both hydrophobic particles and hydrophilic particles, and perform efficient adsorption supplementation. Is considered possible.
For air purification, it is advantageous that the upholstery device is tall and extends from the floor surface to the vicinity of the ceiling. In that case, the air suction port (or the discharge port) by the blower is such that the air flow formed by the blower contacts the entire area of the long wire (and the droplets on the surface) of the tall device as evenly as possible. It is efficient to disperse and arrange in the upper and lower positions.
This device is a method of adsorbing and capturing particulate matter by slowly flowing a viscous liquid to the wire in the form of drops, so a small amount of circulating fluid is sufficient regardless of the large adsorption area, and operating costs are low. I'm sorry. Specifically, the amount of circulating fluid required to flow down to one wire is about 20 cc / min. For example, even if a device with 1000 wires stretched is operated, a small liquid feed of only 20 liters / min. It is economical because it can be a pump and consumes little power.

  The interior decoration device of the invention has a liquid supply pipe for supplying the liquid descending along the wire to the liquid storage dish and a pump provided at a predetermined position of the liquid supply pipe, and upstream of the pump. More preferably, a filter for removing the dust adsorbed by the droplets is connected to the side and / or the downstream side.

According to such an interior decoration device, the dust adsorbed by the droplets is removed by the filter, so that clogging does not occur in the liquid flow path such as a nozzle cylinder that supplies the liquid to the upper part of the wire.
When the dust adsorbed by droplets contains particularly fine particles (particulate matter such as PM2.5), an independent circulation path is provided separately from the above-mentioned supply pipe, and the circulation path It is desirable to incorporate a high-definition filter with the pump inside.

  According to the interior decoration device with an air purifying function of the invention, the work of handing a plurality of wires up and down and the subsequent maintenance are facilitated. In addition, the apparatus can be easily moved. Variations in tension of each wire can be reduced. It is also possible to enhance the decorativeness of the wire and to use the same liquid hygienically for a long time. The wire can be protected so that a person or an object can be prevented from inadvertently touching the liquid or the wire. When the wire is handed up and down for a long time, dust can be adsorbed in a wide range in the top and bottom in the room where the apparatus is installed. Since no noise is generated, the air purifying function is quietly exhibited. By cleaning and replacing the filter, the same liquid can be used for a long time, and maintenance costs and labor are minimal.

It is an enlarged view of c part of a).

  Hereinafter, an embodiment of an interior decoration device according to the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the interior decoration device 1A with an air purifying function includes a plurality of nylon wires 4 (between a distributor assembly 2 provided at the upper portion and a receiver assembly 3 provided at the lower portion. For example, a fishing line 14 made of nylon is handed over and the droplet B is lowered along the wire 4. When light is applied from a projector (not shown) toward the wire 4 or the like, the droplet B scatters the light and the decoration effect is enhanced. The wire 4 may be entirely linear as described above, and although not shown in the drawing, the liquid flows down in a part or all, such as a spiral shape, a zigzag shape, a zigzag shape, a ball chain shape, a net shape, and a belt shape. It may have a shape that can increase the distance and area.

  The distributor assembly 2 includes a liquid reservoir plate 22, an upper lid 27, and a support member 28 (see FIG. 2). The distributor assembly 2 is disposed on a finished ceiling 40 as shown in FIG. Suspended from the upper floor concrete 41.

  As shown in FIG. 2, the liquid reservoir 22 that constitutes the distributor assembly 2 stores the liquid A that becomes the liquid droplets B transmitted through the wire 4, and is formed on a flat bottom portion 22 a having a thickness of 1 mm to 2 mm. A plurality of small holes 22c penetrating vertically are formed by concentrically arranging three small holes. Each small hole 22c is provided with a screw portion (not shown) that is screwed with the screw portion 24a of the hollow bolt 24 shown in FIGS. 3 (a) and 3 (b). The hollow portion of the bolt 24 is a flow path 24 b for the fluid A, and is also a hole through which the wire 4 passes.

  The screw portion 24a of the bolt 24 has an inflow hole 24c connected to the flow path 24b in a portion exposed above the bottom portion 22a of the liquid reservoir tray 22, and the liquid A around the screw portion 24a is in contact with the inflow hole. It is possible to flow into the flow path 24b through 24c. Thus, by providing the inflow hole 24c in the middle of the screw portion 24a, the liquid A in the vicinity of the bottom portion 22a of the liquid reservoir 22 can be surely flowed down to the flow path 24b. Further, even when the flow path 24b is blocked by a later-described bead 25a or the like at the tip of the bolt 24, the liquid A can be allowed to flow into the flow path 24b.

  With respect to such a plurality of bolts 24, the wire 4 is passed through the flow path 24b, and the upper ends thereof are hooked (FIG. 3A). This operation is performed before the bolts 24 are attached to the liquid reservoir 22. For example, first, the head 24d of the hollow bolt 24 is directed downward, and the upper end portion of the wire 4 is inserted into the flow path 24b from the head 24d side. The bead 25a constituting the retaining member 25 may be passed through the tip of the wire 4 that has passed through the screw portion 24a, and the crimp terminal 25b may be further attached by crimping to the tip. Here, the size of the retaining member 25, that is, the size of the bead 25 a and the crimp terminal 25 b, can pass through the small hole 22 c of the liquid reservoir 22. In addition, the size of the bead 25a cannot pass through the flow path 24b of the bolt 24, and the size of the crimp terminal 25b cannot pass through the hole (not shown) of the bead 25a.

  The bolt 24 in a state of being hooked through the wire 4 as described above can be easily fixed to the liquid reservoir 22 by screwing into the small hole 22c of the liquid reservoir 22 from below. From this point, in the interior decoration device 1A, it is not necessary to tie the wire 4 at the top of the device 1A, and the wire 4 can be easily hung from the top of the device 1A. It can be safely installed. Since the bolt 24 can be repeatedly attached to and detached from the small hole 22c of the liquid reservoir tray 22, the same merit is obtained not only when the wire 4 is newly attached but also when the wire 4 is replaced by maintenance.

As shown in FIG. 3A, the head 24d of the bolt 24 is rounded by chamfering around the end surface. In the conventional upholstery device, as shown in FIG. 14C, the lower surface 122b of the liquid reservoir 122 is flat, so that the decorative liquid A that has passed through the small holes 124 moves the lower surface 122b of the bottom 122a laterally. In some cases, it did not descend along the overhead line 140. However, in this decoration device 1A, only the head 24d of the bolt 24 protrudes downward from the lower surface 22b of the liquid reservoir 22 and the periphery of the head 24d is rounded, so that the liquid A is in the liquid reservoir 22 Therefore, the liquid A (droplet B) can be reliably lowered along the wire 4.
Further, as shown in FIG. 3A, a packing 26 is provided between the head 24 d of the bolt 24 and the bottom 22 a of the liquid reservoir 22. As a result, the situation in which the liquid A stored in the liquid storage tray 22 leaks from between the bolt 24 and the liquid storage tray 22, spreads on the lower surface 22 b of the bottom 22 a of the liquid storage tray 22, and falls from a place other than the wire 4. Is preventing.

As shown in FIGS. 1 and 2, the receiver assembly 3 is fixedly installed on a mount 5.
As shown in the lower part of FIG. 2, the receiver assembly 3 includes a liquid receiving tray 32 installed on the gantry 5, a decorative plate 33 provided horizontally in the interior thereof, and punching for connecting the wire rods 4 attached to the lower side thereof. The porous plate 34 further includes a movable plate 36 that is fixed to the punching porous plate 34 and adjusts the tension of the wire 4. A liquid feed pipe 63 described later is connected to the bottom of the liquid receiving tray 32.

  The decorative board 33 is for hiding the attachment part of the wire 4, and improving the aesthetics of the apparatus 1A. The decorative plate 33 is formed with a hole 33a for allowing the wire 4 and the droplet B to pass therethrough. Each wire rod 4 hung on the bolt 24 of the liquid reservoir tray 22 is passed through the mounting hole 34a of the punching perforated plate 34 after the lower end portion is passed through the hole 33a of the decorative plate 33. The wire 4 is hung on the perforated perforated plate 34 by attaching the crimp terminals 35 wider than the inner diameter of the attachment hole 34a to the tip portion of the wire 4 passed through.

  The lower part of the perforated perforated plate 34 is joined to the movable plate 36. The movable plate 36 is connected to a fixed member 37 fixed to the liquid receiving tray 32 below by an adjusting bolt 38 and a nut 38a. Since the height of the movable plate 36 can be changed within a predetermined range depending on the tightening state of the bolts 38, the tension of the plurality of wires 4 connected to the punching perforated plate 34 can be adjusted uniformly.

As shown in FIG. 1, the gantry 5 on which the receiver assembly 3 is installed integrally forms machine rooms 6 and 8 having an upper lid 51. The machine rooms 6 and 8 are provided below the floor or on the lower floor.
The machine chamber 6 accommodates a liquid feeding pump 61, and the liquid receiving tray 32 and the liquid reservoir tray 22 are connected via a liquid feeding pipe 63 connected to the pump 61. A filter 62 for removing dust adsorbed while the droplet B descends the wire 4 is connected to the upstream side and the downstream side of the liquid feed pump 61.

The droplet B that travels down the hole 33 a (FIG. 2) of the decorative plate 33 through the wire 4 further passes through a gap (not shown) between the fixing members 37 and is accommodated in the bottom of the liquid tray 32. The liquid A that has entered the liquid receiving tray 32 in this way is supplied again to the upper liquid reservoir 22 by the liquid supply pipe 63 and the pump 61 shown in FIG. The droplets B adsorb particles of various sizes such as dust, cigarette smoke, and bacteria contained in the air. The filter 62 is connected before and after the pump 61 to remove these dusts. Therefore, the liquid A returned to the clean state can be supplied to the liquid reservoir 22. Therefore, the air is gradually cleaned by repeatedly dropping the liquid A as the droplet B along the wire 4. The pump 61 is provided with a thermostat and is set to be turned off when the temperature of the liquid A rises so that the liquid A does not ignite. The filter 62 preferably employs a wire net or a resin net of about 60 μm.
When the dusts contain a lot of fine particles (PM2.5, etc.), the filter 62 provided in the liquid feed pipe 63 is not made highly accurate (flow passages / small holes such as bolts 24). And a new independent path (not shown) including another pump for circulating the liquid A in the liquid receiving tray 32 is provided, and a high-precision (fine) is provided in the circulation path. ) A filter (such as one containing activated carbon) should be incorporated. In that case, a small pump and filter in the circulation path are sufficient, and the filter 62 is not easily clogged, so the load on the pump 61 is kept small.

  In order to promote air purification, the machine room 8 accommodates an air circulation fan 71, and an intake pipe 7 is provided in the vertical direction at the center position of the wire 4 arranged along a triple circle. ing. The intake pipe 7 is provided with intake holes 7a at a number of locations on the side surface having different heights. Via the air duct 73 connected to the air circulation fan 71, the intake pipe 7 and the outlet 75 of the vent cap 74 attached to the finished ceiling 16 are connected. Therefore, the air around the intake pipe 7 can be sucked by the air circulation fan 71, and the sucked air is discharged from the outlet 75 and circulates in the room. When the air moves in this way, a large amount of air is positively brought into contact with the droplets B descending the wire 4, so that the cleaning of the indoor air is promoted. When the density of the wire 4 (the number of stretches per unit area) is increased, the air can be more effectively cleaned. Further, the air duct 73 is connected with an air filter 72 with activated carbon for removing indoor dust and the odor of the droplet B.

  The machine room 8 further accommodates a mist pump 81. One of the mist pumps 81 is connected to the water pipe 9, and the other is connected to a mist nozzle 85 incorporated in the vent cap 74 of the ceiling 16 via a mist water supply pipe 83. Therefore, when the mist pump 81 is operated, the water supplied from the water pipe 9 passes through the mist water supply pipe 83 and is sent as mist from the mist nozzle 85 near the ceiling 16 into the room together with the circulating air. Can prevent drying. In order to adjust the humidity in the room, the mist pump 81 may be controlled using a humidity sensor (not shown).

  As the liquid A flowing along the wire 4, a mixture of triethylene glycol, which is a kind of polyhydric alcohol, and polyethylene glycol with water is used. Triethylene glycol has an appropriate viscosity and is easy to form droplets B, and does not evaporate or change quality. Therefore, the same liquid can be used for a long time without replenishment or replacement. Furthermore, since polyethylene glycol does not separate from water, liquid A having an appropriate viscosity can be obtained, and since it has a high flash point and is safe, it is optimal for a decoration device used indoors. Liquid A may use triethylene glycol alone. In addition, a fluorescent agent, a bactericidal agent, and aroma oil may be added to the liquid A (however, the liquid A is not changed). For example, it is also preferable to add alkanediol having a high bactericidal effect.

FIG. 4 shows a receiver assembly 31 that holds the lower end portion of the wire rod 4 in a manner different from that of the receiver assembly 3 described above. Constituent elements common to the receiver assembly 3 are denoted by the same reference numerals, and description thereof is omitted.
In the receiver assembly 31, a spring coil 39 is connected to the lower part of each wire 4. The spring coil 39 has a mounting hole 39a through which the lower end portion of the wire 4 passes. The lower end portion of the spring coil 39 is attached to the upper surface of the fixing member 37 via a support member 39b. The fixing member 37 is fixed to the bottom of the liquid tray 32 using fixing bolts 37a and nuts 37b.

  As described above, the wire rods 4 hung on the bolts 24 of the liquid reservoir tray 22 are passed through the mounting holes 39a of the spring coil 39 after the lower end portions thereof are passed through the holes 33a of the decorative plate 33, respectively. The wire 4 is hung on the spring coil 39 by attaching a crimp terminal 35 having a width wider than the inner diameter of the attachment hole 39a to the tip of each wire 4 passed through. Since the spring coil 39 has elasticity, even if the tension of the plurality of wire rods 4 connected to the spring coil 39 varies, any wire rod 4 can be hooked so as not to loosen.

5 and 6 are cross-sectional views of a state in which a wire 44 as another embodiment is handed up and down, as viewed from below.
The wire 44 has an upper end portion and a lower end portion that are linear like the wire rod 4 described above, but has a strip-like portion 44a in other portions. The strip-shaped portion 44a is preferably in a shape close to a ribbon, for example, having a width of about 5 to 20 times the thickness. A plurality of grooves (not shown) extending in the vertical direction are formed on the wide surface 44b. Therefore, the liquid A is easy to spread and flow over the entire area without being biased to a part of the wide surface 44b, so that the liquid A can be brought into contact with air in a wide area. Similarly to the wire 4 described above, the upper end portion of the wire 44 is hung on the bolt 24 shown in FIGS. 2 and 3 and then attached to the liquid reservoir 22, and the lower end portion is hung on the punching perforated plate 34. The spring coil 39 is connected.
For the wide surface 44b, in order to make the liquid A spread and flow easily, in addition to forming a plurality of grooves as described above, the surface 44b may be a fine uneven surface or a hydrophilic surface. Good.

The direction of the wire 44 is determined so that a wide surface 44b includes a large amount not parallel to the air flow.
In FIG. 5, the wire 44 determines the direction of the band-shaped portion 44 a so that the indoor air flow C hits the wide surface 44 b at a right angle, and passes it up and down. Therefore, since the airflow C hits the wide surface 44b from the front, the liquid A flowing on the surface easily adsorbs dust. In this embodiment, the small holes 22c of the liquid reservoir 22 are arranged in a plurality of rows at the same pitch, and are shifted so as not to overlap in the front and rear rows when viewed from the upstream side of the air flow C. ing. Therefore, the air hitting the wide surface 44b of the wire rod 44 in the front row from the front passes through between the adjacent wire rods 44 and hits the wide surface 44b of the wire rod 44 in the rear row from the front. The liquid A flowing above tends to adsorb dust.
In the example of FIG. 6, the wide surface 44b of the wire 44 is rotated by 45 °. Since the direction of rotation is reversed every other row, the wide surfaces 44b of the wire rods 44 in the front and rear rows are oriented at right angles to each other. In this case, the air flow C hits the wide surface 44b of the wire 44 in the front row at an angle of 45 °, but the flow angle changes on the surface, and the wide surface 44b of the wire 44 in the back row You will hit from the front. Therefore, the liquid A flowing on each surface is also likely to adsorb dust.

  The wide surface 44b of each wire 44 is fixed in orientation by, for example, forming a groove (not shown) on the lower surface of the head 24d of the bolt 24 and fitting the upper end of the strip-shaped portion 44a into the groove. Can do. It is also possible to form a slit (not shown) in a specific direction on the upper surface of the decorative plate 33 and insert the lower end of the band-shaped portion 44a into the slit to fix the direction. It is more preferable to combine both.

7 and 8 show another embodiment of a mobile upholstery device 1B with an air purifying function. 7 is a schematic longitudinal sectional view thereof, and FIG. 8 is a sectional view taken along the line VIII-VIII of FIG.
In this interior decoration device 1B, a distributor assembly (liquid reservoir tray) 200 and a receiver assembly (liquid receiver tray) 300 each having a square cross section are assembled to a frame 10 with casters 20. Since the caster 20 is provided, the apparatus 1B can be easily moved.
The frame 10 is formed by connecting a lower mechanical box 11 and an upper distributor assembly 200 with pillars 13 standing at four corners. The distributor assembly 200 is incorporated in the upper frame 12, and the receiver assembly 300 is incorporated in the mechanical box 11. Similar to the above-described apparatus 1 </ b> A, a plurality of wires 4 are delivered between the distributor assembly 200 and the receiver assembly 300. As shown in FIG. 8, the wire 4 is arranged in a five-fold square shape here.

  A plurality of barrier wires 14 are handed over between the upper frame 12 and the mechanical box 11 at a position where the droplets B do not descend on the outermost periphery of the wire 4. The barrier wires 14 are arranged in a row at 1 cm intervals. Since the wire 4 is surrounded by the barrier wire 14, it is possible to prevent a person or an object around the apparatus 1 </ b> B from touching the falling liquid droplet B or pulling the wire 4 to cut it. Moreover, as compared with the case of surrounding with an acrylic board or the like, it is surrounded by a thin thread, so that the aesthetic appearance is not impaired and the cost is advantageous.

  Although not shown, the distributor assembly 200 and the receiver assembly 300 include configurations similar to those included in the distributor assembly 2 and the receiver assembly 3 of the above-described embodiment (FIG. 1 and the like), respectively. (The same code | symbol is attached | subjected to the common component part.). Further, the mechanical box 11 includes a pump 17 for supplying the liquid A stored in the liquid receiving tray to the upper liquid storage tray, and a suction side filter 18A and a discharge side filter 18B of the pump 17. Accordingly, the droplet B (liquid A) descending along the wire 4 from the liquid reservoir of the distributor assembly 200 is accommodated in the liquid receiver of the receiver assembly 300 and flows into the storage tank 15, and then the pump 17 The adhering dust and the like are separated through the feed pipe 19 connected to the filters 18A and 18B, and returned to the liquid reservoir plate of the distributor assembly 200 again. Of the four columns 13, one column 13A is hollow, and the feed pipe 19 is connected to the lower portion of the column 13A so that the liquid A returns to the liquid storage dish through the column 13A. Yes. Further, another support column 13 is provided with a hollow support column 13A, which is used as a return pipe for the overflow when the liquid A overflows from the reservoir pan. If the support 13 is used in this way, there is no need to provide a pipe dedicated to feeding the liquid A outside the wire 4, which is advantageous in terms of the appearance of the apparatus.

  Further, the mechanical box 11 is provided with a storage tank 15 for storing the liquid A, and is connected to the feed pipe 19 via the detachable coupler 16. Therefore, it is possible to easily remove the storage tank 15 and perform maintenance such as replacement of the liquid A. The storage tank 15 is a sealed type having only an air vent hole (with a valve). As the detachable coupler 16, for example, an SP coupler (trade name) manufactured by Nitto Kohki Co., Ltd. is used. Use of a two-way open / close pipe joint that closes both the storage tank 15 side and the feed pipe 19 side when separated is advantageous in reducing dripping.

  For the interior decoration apparatus with an air cleaning function described above, an experiment on the cleaning power of liquid and air was conducted. In the experiment, an upholstery device with an air cleaning function in which 60 wires are arranged in the same manner as in the apparatus 1A of FIG. 1 and delivered to the upper and lower assemblies and an intake pipe is arranged in the center is 150 mm in diameter and 700 mm in height. Stored in an acrylic cylinder. While the liquid for liquid droplets is circulated while being cleaned with a filter, the air inside the cylinder sucked out by the intake pipe is passed through a box filled with cigarette smoke and then returned to the cylinder. Although it became cloudy, the transparent state gradually recovered after a few minutes.

  Moreover, about the liquid, the change of the number of general viable bacteria when using it for a long time with the interior decoration apparatus of the same shape as the thing of FIG. 1 was measured. The liquid used for this measurement is a liquid (triethylene glycol) after being used in a yakiniku store for more than 10 years as a liquid for droplets, and a new triethylene glycol for comparison. When the number of general viable bacteria in each liquid was examined by the standard agar medium bacterial count method by requesting the Health and Environment Center of the Hyogo Prefectural Medical Association, neither of them was inhabited (general live bacteria) Number: 0.0-1.0 × 10 / g). That is, it can be said that the interior decoration device with an air cleaning function can maintain the cleanliness of the liquid even when the same liquid is circulated for a long time.

Another embodiment of the interior decoration device according to the invention will be described with reference to FIGS.
As shown in FIGS. 9 and 11, the interior decoration device 1C includes a plurality of nylon wires 4 (for example, made of nylon) between a distributor assembly 2 provided in an upper portion and a receiver assembly 3 provided in a lower portion. The fishing line 14) is handed over and the droplet B is lowered along the wire 4. When light is applied from a projector (not shown) toward the wire 4 or the like, the droplet B scatters the light and the decoration effect is enhanced.

  The liquid reservoir 22 contained in the distributor assembly 2 is for storing the liquid A as the droplet B, and is arranged vertically on a circular / flat bottom portion 22a (FIG. 9B) having a thickness of 1 mm to 2 mm. A plurality of through-openings 22c are formed in a concentric triple manner. A hole suitable for passing the wire 4 and the droplet B is formed in each opening 22c by inserting a blind rivet 24 (sleeve 24a) shown in FIG. As the blind rivet 24, a sleeve 24a having a flange-like seat portion 24b and a shaft portion 24e integrated with a metal ball 24c larger than the inner diameter of the sleeve 24a is used. The sleeve 24a having an inner diameter of about 2 mm is inserted into the opening 22c so that the seat portion 24b faces downward, and then the shaft portion 24e is strongly caulked downward by a riveter tool (not shown). At this time, the shaft portion 24e is cut, and the metal ball 24c remains at the end of the crushed sleeve 24a (the left end diagram of FIG. 10A). Thereafter, a punching rod (not shown) is inserted inside the blind rivet 24, and the metal ball 24c is punched upward using a hammer (not shown) and removed from the sleeve 24a. By doing in this way, the inside of the sleeve 24a of the blind rivet 24 can be made into a small hole 24d penetrating vertically.

  Each wire 4 is passed over these small holes 24d so as to straddle two adjacent small holes 24d (FIGS. 10A and 11). This operation can be performed as shown in FIGS. 12A to 12C only from the bottom of the liquid reservoir 22. For example, first, a thread ring 4X is inserted from the bottom of one small hole 24d of the liquid reservoir 22 toward the top, and the bottom of the other small hole 24d is directed from the bottom to the top inside the thread ring 4X. Then, one end of the wire 4 passed through is passed (FIG. 12A). After that, when the yarn ring 4X is pulled downward from the original small hole 24d (FIG. 12B), the ring 4X is pulled downward together with the wire 4 from the original small hole 24d (FIG. 12C). ), The wire 4 is folded back across the two small holes 24d. Thereby, the both ends of the wire 4 can be hung from the liquid reservoir 22. If the liquid reservoir 22 is transparent or translucent, the above operation can be easily performed from under the liquid reservoir 22.

  When the small hole 24d is formed as described above by the blind rivet 24 shown in FIG. 10, the seat portion 24b of the sleeve 24a protrudes downward at the lower end portion of the small hole 24d. Therefore, the liquid A coming out of the small hole 24d descends along the wire 4 from the protruding portion, and does not travel in the lateral direction on the bottom lower surface 22b of the liquid reservoir 22.

  Further, when the blind rivet 24 is caulked, the upper end portion of the sleeve 24a is in strong contact with the metal ball 24c, so that the upper end portion of the sleeve 24a has no burr and the surface is smooth. Therefore, even when the wire 4 is stretched over the two small holes 24d and both ends of the wire 4 are fixed at the lower part and tension is applied to the wire 4, the wire 4 is connected to the upper end of the small hole 24b. There is no inconvenience of being easily cut by contact.

  In addition, it can replace with such a liquid reservoir 22 and can also use the liquid reservoir 23 as shown in FIG.10 (c) which does not use a blind rivet. The liquid reservoir 23 has a small hole 26 formed directly in the bottom 23a, and a protruding portion 26a projecting downward from the lower surface 23b of the bottom 23a is formed at the lower end of each small hole 26 by molding. Since there is this protruding portion 26a, it is possible to prevent the liquid A descending the small hole 26 from being transmitted laterally on the lower surface 23b of the bottom 23a. Furthermore, a smooth curved surface having no edge or burr is formed at the upper end portion of each small hole 26. Therefore, similarly to the case of the liquid reservoir 22, even if the wire 4 passed over the two small holes 26 comes into contact with the upper end portion of the small hole 26, it is difficult to be cut.

  As shown in FIG. 11, the liquid reservoir tray 22 is provided with an upper lid 27. The upper lid 27 is connected to the liquid reservoir tray 22 via a suspension support member 28. The suspension support member 28 is attached to a ceiling (not shown) or another support member (same) by suspension bolts (not shown).

  The receiver assembly 3 has the structure shown in the lower part of FIG. That is, a liquid receiving tray 32 provided on the gantry 5, a decorative plate 33 provided horizontally inside thereof, a punching perforated plate 34 for fixing the wire 4 attached below, and further fixed to the punching perforated plate 34. And a movable plate 36 for adjusting the tension of the wire 4.

  The decorative board 33 is for hiding the attachment part of the wire 4, and improving the aesthetics of the apparatus 1C. The decorative plate 33 is formed with a hole 33a for allowing the wire 4 and the droplet B to pass therethrough. Each wire 4 passed over the small hole 24 of the liquid reservoir tray 22 passes through the hole 33a of the decorative plate 33 at both ends, and then passes through the mounting hole 34a of the punching porous plate 34. The wire 4 is hung on the perforated perforated plate 34 by attaching the crimp terminals 35 wider than the inner diameter of the attachment hole 34a to the tip portion of the wire 4 passed through.

  The lower part of the perforated perforated plate 34 is joined to the movable plate 36. The movable plate 36 is connected to a fixed plate 37 fixed to the liquid receiving tray 32 below by an adjusting bolt 38 and a nut 38a. Since the height of the movable plate 36 can be changed within a predetermined range depending on the tightening state of the bolt 38, the tension of the plurality of wires 4 fixed to the punching perforated plate 34 can be adjusted uniformly.

The liquid droplet B descending through the hole 33a of the decorative plate 33 through the wire 4 further passes through a hole (not shown) provided in the fixed plate 37 and is accommodated in the liquid receiving tray 32. The liquid A that has entered the liquid receiving tray 32 in this way is supplied again to the liquid storage tray 22 by the feed pipe 6 shown in FIG. 9 and the pump 62 provided in the middle thereof. The droplets B adsorb particles of various sizes such as dust, cigarette smoke and bacteria contained in the air. Filters 64 are connected before and after the pump 62 to remove these dusts. Therefore, the liquid A returned to the clean state can be supplied to the liquid reservoir 22. Therefore, the air is gradually cleaned by repeatedly dropping the liquid A as the droplet B along the wire 4. The pump 62 is provided with a thermostat and is set to be turned off when the temperature of the liquid A rises so that the liquid A does not ignite. The filter 64 preferably employs a wire net or a resin net of about 75 μm so that nicotine and the like can be removed. Here, a GF filter is used.
When the dusts contain a lot of fine matters (PM2.5 or the like), the filter 64 provided in the feed pipe 6 is not made highly accurate (with PP of about 100 μm), but in the liquid tray 32. It is preferable to newly provide an independent path (not shown) including another pump for circulating the liquid A, and to incorporate a high-precision (fine) filter in the circulation path. In this case, a small pump and filter in the circulation path are sufficient, and the filter 64 is not easily clogged, so that the load on the pump 62 is kept small.

  In order to promote air purification, in the interior decoration device 1C, an intake pipe 7 is provided vertically in the center of the wire 4 arranged along the triple circle as shown in FIG. The intake pipe 7 is provided with intake holes 72 at a number of different heights on the side surface, and air around the intake pipe 7 can be sucked in by an intake fan 74 provided at the top. The air sucked into the intake pipe 7 is discharged from an air supply port 76 arranged at another place in the room and circulates in the room. Accordingly, since a large amount of air is positively brought into contact with the droplets B descending the wire rod 4, the cleaning of the indoor air is promoted. Increasing the density of the wire 4 (the number of stretches per unit area) increases the number of droplets B, so that the air can be more effectively cleaned.

  As the liquid A, a mixture of triethylene glycol, which is a kind of polyhydric alcohol, and polyethylene glycol with water is used. Triethylene glycol has an appropriate viscosity and is easy to form droplets B, and does not evaporate or change quality. Therefore, the same liquid can be used for a long time without replenishment or replacement. In addition, there is an advantage that it does not smell even if tobacco smoke is adsorbed. Furthermore, since polyethylene glycol does not separate from water, liquid A having an appropriate viscosity can be obtained, and since it has a high flash point and is safe, it is optimal for a decoration device used indoors. Liquid A may use triethylene glycol alone. Further, a fluorescent agent or a bactericidal agent may be added to the liquid A.

FIG. 13 shows an interior decoration device 1D which is another embodiment. The interior decoration device 1D is formed by delivering a plurality of wires 4 between a rectangular distributor assembly 12 provided near the ceiling of the room D and a receiver assembly 13 installed on a floor 15. Each of the assemblies 12 and 13 extends linearly across the width of the room D, and the plurality of wire rods 4 spanned between them are a plurality of parallel plurals having a width almost equal to dividing the space of the room D into two. It is arranged along a plane.
Although not shown, the distributor assembly 12 and the receiver assembly 13 include the same elements as those included in the distributor assembly 2 and the receiver assembly 3 of the above-described embodiment (FIG. 9 and the like). . Accordingly, the droplet B (liquid A) descending along the wire 4 from the liquid reservoir of the distributor assembly 12 is accommodated in the liquid receiver of the receiver assembly 13 and the feed pipe connecting the pump 62 and the filter 64 is connected. 6, the attached dust and the like are separated, and the liquid is again returned to the liquid collecting pan of the distributor assembly 12.

  In the wire 4 having such an arrangement, since there is no space surrounded by the wire 4, the air intake duct 17 in which the intake gallery 17 b and the blow gallery 17 c provided on the wall of the room D are arranged outside the room D is provided. The air in the room is circulated by an air pump 17a connected in the middle of the air supply duct. A filter 17d is connected to the air supply duct 17 to remove dust in the air. In this case, it is more possible to arrange the wires 4 in a plurality of rows at the same pitch and to shift the rows so that none of the wires 4 overlap when viewed from the intake gallery 17b side. The droplet B can be brought into contact with air, and the indoor air can be effectively cleaned.

  For the interior decoration apparatus described above, an experiment on the cleaning power of liquid and air was conducted. In the experiment, an interior decoration device in which 60 wires were arranged in the same manner as in FIG. 9 and delivered to the upper and lower assemblies and an intake pipe was arranged in the center was stored in an acrylic cylinder having a diameter of 150 mm and a height of 700 mm. While the liquid for liquid droplets is circulated while being cleaned with a filter, the air inside the cylinder sucked out by the intake pipe is passed through a box filled with cigarette smoke and then returned to the cylinder. Although it became cloudy, the transparent state gradually recovered after a few minutes. When the liquid odor was examined after that, almost no tobacco odor was felt.

  Moreover, about the liquid, the change of the number of general viable bacteria when it uses for a long time with the interior decoration apparatus of the same shape as FIG. 9 was measured. The liquid used for this measurement is a liquid (triethylene glycol) after being used in a yakiniku store for more than 10 years as a liquid for droplets, and a new triethylene glycol for comparison. When the number of general viable bacteria in each liquid was examined by the standard agar medium bacterial count method by requesting the Health and Environment Center of the Hyogo Prefectural Medical Association, neither of them was inhabited (general live bacteria) Number: 0.0-1.0 × 10 / g). That is, it can be said that the interior decoration device can maintain the cleanliness of the liquid even when the same liquid is circulated for a long time.

  As described above, according to the interior decoration device with an air cleaning function of the invention, assembly and maintenance of the device are easy and safe. In addition to the droplets always falling smoothly along the wire, there is an advantage that the same liquid can be circulated for a long period of time. Since the air in the space where the device is installed is cleaned and the liquid is viscous and does not scatter like water, it is ideal as a decoration device for indoor use. Also, it is quiet because there is no sound. There is no need to replace the liquid for a long period of time, and it is only necessary to clean and replace the filter.
