In configuring the present invention, the predetermined container is preferably a bathtub.
This configuration enables efficient filtration and antibacterial treatment of the bath water contained in the bathtub, which not only contributes to the saving of bath water, but also facilitates secondary use. Can do.
In addition, when the predetermined container is a bathtub, as a so-called throw-in type filtration device, it is possible to effectively exhibit the features of small size, good usability, efficient filtration processability and antibacterial treatment ability.

As illustrated in FIGS. 1A to 1B, the present invention includes a pump unit 11 for sucking water 18 contained in a predetermined container 19, and water in the predetermined container 19 by the pump unit 11. The water absorption part 12 for inhaling 18 and the water discharge part 14 for discharging the water 18 which the water absorption part 12 inhaled as filtered water through the filter medium 13 containing antibacterial glass and the water absorption part 12 are fixed. And a support device 15, wherein the water absorption portion 12 is connected to the support portion 15 via a flexible pipe 17. 10.
That is, FIG. 1A is a diagram provided for explaining the basic configuration of the filtration device 10, and FIG. 1B is a diagram provided for explaining a method of using the filtration device 10.
Hereinafter, the embodiment of the filtration device 10 of the present invention will be described in detail by dividing it into each component.

1. Pump part (1) Type of pump The type of pump used in the pump part 11 illustrated in FIGS. 1 (a) to 1 (b) is appropriately determined in consideration of the type of a predetermined container to which the present invention is applied and the filtration rate. A known pump can be selected.
Therefore, for example, non-positive displacement pumps such as a centrifugal pump, a propeller pump, and a cascade pump, and positive displacement pumps such as a piston pump and a rotary pump can be used.
Among these, the pump type is preferably a centrifugal pump or a propeller pump.
The reason for this is that these pumps are relatively small in structure, and can absorb bath water and the like economically and stably and perform filtration.
As a power source for the pump, an AC power source or a DC power source is appropriately selected according to the scale of the bathtub and the pump standard.

(2) Pump capacity The pump capacity can be determined in consideration of the size of the predetermined container and the filtration time of the treated water, but is usually a value within the range of 0.5 to 30 liters / minute. Is preferred.
The reason for this is that when the pump capacity is less than 0.5 liter / min, it may be difficult to efficiently suck floating matters or the like.
On the other hand, if the pump capacity exceeds 30 liters / minute, excessive pressure may be applied to the water discharge part or the like, and the movement speed of the sucked water may be high, so that sufficient antibacterial treatment may be difficult. It is.
Therefore, the pump capacity is more preferably set to a value within the range of 1 to 20 liters / minute, and further preferably set to a value within the range of 4 to 10 liters / minute.

2. Water-absorbing part (1) Number of water-absorbing parts The water-absorbing part 12 illustrated in FIGS. 1 (a) to 1 (b) is water (in the case of a liquid other than water) accommodated in a predetermined container 19 via the pump part 11. Yes, the same applies hereinafter.) This is a component for sucking in 18.
Therefore, the number of the water absorbing portions can be changed as appropriate according to the size of the predetermined container, but may be one as illustrated in FIGS. 1A to 1B, for example. . Or it is also preferable to provide a some water absorption part so that it may mention later.
That is, as illustrated in FIGS. 3A to 3C, the water absorbing portion is a plurality of water absorbing portions 12 including a first water absorbing portion 12 ′ and a second water absorbing portion 12 ″. The water absorbing portion 12 ′ is a water absorbing portion for sucking the bottom water 18 in the predetermined container 19, and the second water absorbing portion 12 ″ is the water absorbing portion for sucking the water 18 on the water surface in the predetermined container 19. 12 is preferable.
The reason for this is that the filtration process and the antibacterial process can be performed simultaneously in the vicinity of the water surface where a lot of suspended solids exist and the bottom part where there is a large amount of precipitates.
Therefore, for example, by manually moving the water absorption part directly or changing the water absorption position automatically, filtration treatment and antibacterial treatment are performed on water at an arbitrary position accommodated in a predetermined container. be able to.

(2) Shape of the water absorbing portion The shape of the water absorbing portion can be appropriately selected in consideration of the water absorption range, the water absorption speed, and the like.
Therefore, as shown in FIGS. 2A to 2D, the shape of the water absorbing portion 12 is at least one shape selected from a circular shape 21, an elliptical shape 22, a rectangular shape 23, and a tapered shape 24. preferable.
This is because, when the shape of the water absorbing portion is a quadrangular shape, a circular shape, or an elliptical shape, a wide range of water in the container can be easily absorbed.
Moreover, when the shape of a water absorption part is a taper shape, it is because powerful strong suction is attained by an orifice effect.

Moreover, as shown in FIG.2 (e), it is preferable to provide the mesh structure 25a of predetermined roughness in the inside of the water absorption part 12, or the water absorption port 25. As shown in FIG.
This is because a relatively large suspended matter or the like can be removed in advance by the mesh structure before moving to the pump unit or the water discharge unit. Therefore, it is possible to efficiently purify, and to prevent a decrease in suction performance or a failure due to clogging inside the filtration device.

In addition, when providing the mesh structure of predetermined roughness, it is preferable to make the number of meshes into the value within the range of 2-12 meshes / 1 inch (25.4 mm).
This is because when the number of meshes is less than 2, it may be difficult to capture even a relatively large suspended matter. On the other hand, when the number of meshes exceeds 12, on the contrary, fine suspended matters are excessively captured, so that clogging occurs frequently and the suction force may be reduced.
Therefore, when a mesh structure having a predetermined roughness is provided at the water inlet, the number of meshes is more preferably set to a value within the range of 3 to 11 mesh / 1 inch (25.4 mm). More preferably, the value is within a range of 1 inch (25.4 mm).

(3) Position fixing member As shown in FIG. 3 (a), a plurality of water absorbing portions 12 including a first water absorbing portion 12 ′ and a second water absorbing portion 12 ″ are provided, and FIG. As shown in FIG. 4, at least one of the water absorbing portions 12 (the first water absorbing portion 12 ′ and the second water absorbing portion 12 ″) has a position fixing member 31 for arbitrarily adjusting the water absorbing position. Is preferred.
The reason for this is to enable suction of water at such a water level by manually or automatically fixing the water absorbing portion at a predetermined water level using such a position fixing member.
In other words, with this configuration, the water absorption position of the water absorption part can be determined easily and quickly, and even with a so-called throw-type filtration device, the filtration process and the antibacterial process at the desired position are more efficiently performed. can do.

Further, the position fixing member is not particularly limited as long as it is a means for stably and easily fixing the water absorbing portion to the support member. Usually, a screw structure, a clamp structure, a fitting structure, and a magnet structure are used. Preferably, the structure is at least one structure selected from the group consisting of:
The reason for this is that, in the case of such a structure, since the structure itself is simple, the filtration apparatus is less likely to be excessively large. On the other hand, when the filtration apparatus is used, water is easily and firmly absorbed. This is because the position of the part can be fixed.

Further, as shown in FIG. 3C, the position fixing member is arranged such that at least one of the plurality of water absorbing portions 12 including the first water absorbing portion 12 ′ and the second water absorbing portion 12 ″ floats on the water surface. The buoyancy member 32 is preferably provided.
The reason for this is that by providing the buoyancy member, the water absorption part floats on the water surface, so that water including floating substances and the like existing near the water surface can be absorbed and the floating substances and the like can be effectively removed. . Further, even when the water level changes frequently, the position of the water absorption part is automatically adjusted by the buoyancy member so as to be close to the water surface, and suspended matter and the like can be effectively removed. Because.

In addition, a buoyancy member means the member which can position a water absorption part substantially in the water surface vicinity by own buoyancy.
Therefore, as the buoyancy member, for example, a foamed polymer structure such as foamed polymer such as foamed polystyrene, foamed urethane, and foamed silicone rubber, or a gas bag such as air, and a bag structure in which air or the like is sealed with a resin having a high gas barrier property is preferable.

3. Water discharge part (1) component parts The water discharge part 14 illustrated by Fig.1 (a)-(b) uses the water 18 which the water absorption part 12 inhaled as filtered water through the filter medium 13 containing antibacterial glass. This is a structural part for discharging to the outside.
Therefore, it is preferable to provide a used beverage container, for example, filled with a filtering agent containing antibacterial glass as a component of the water discharger.
This is because such a used beverage container such as a PET bottle can be reused as a water discharge part effectively and inexpensively, and can be reused as a recycled resource as it is after use.

In addition, when the filter material with which the inside of the water discharging part was made from the synthetic resin, when the antibacterial glass disappears, the water discharging part can be recovered as a recycled resource as it is after being detached from the filtering device.
Further, when the filter medium is not composed only of a synthetic resin, that is, when it is composed of a composite resin with a metal or the like, it is preferable that the filter medium is removed and then recovered as a recycled resource.

(2) Switching valve Moreover, as shown to Fig.4 (a), the water discharging part 14 has 1st water discharging part 14 'which has antibacterial glass whose elution rate of antibacterial ion is comparatively slow, and elution of antibacterial ion A switching valve for switching a flow path for the first water discharging unit 14 ′ and the second water discharging unit 14 ″, and a second water discharging unit 14 ″ having antibacterial glass having a relatively high speed. 41 is preferably provided.
The switching valve 41 is preferably controlled by a signal from at least one control device selected from the group consisting of a temperature sensor, an ion concentration sensor, a turbidity sensor, and a time timer.
The reason for this is that by providing such a switching valve, the flow path can be appropriately switched according to conditions such as water temperature and water quality, and the supply amount and type of antibacterial ions can be arbitrarily selected.
For example, when the water temperature is relatively high or the water quality is good, it is preferable to use the first water discharge part in which antibacterial glass having a relatively low elution rate of antibacterial ions is disposed. On the other hand, when the water temperature is relatively low or the water quality is poor, it is preferable to use the second water discharge part in which antibacterial glass having a relatively high antibacterial ion elution rate is disposed.
Therefore, by providing a predetermined switching valve, it is possible to prevent excess or deficiency of antibacterial ions and to supply different antibacterial ions according to efficient supply of antibacterial ions and conditions.

The dissolution rate of antibacterial ions in the antibacterial glass is relative, but more specifically, when the dissolution rate of the antibacterial ions is relatively slow, the dissolution amount of the antibacterial ions (for example, silver ions) Is a value within a range of 0.01 to less than 1 mg / (g · 24 Hrs · 30 ° C.).
On the other hand, the case where the dissolution rate of antibacterial ions is relatively fast is a value within a range of 1 to 100 mg / (g · 24 Hrs · 30 ° C.) of the dissolution amount of antibacterial ions (for example, silver ions).
And the elution rate of the antimicrobial ion in this antimicrobial glass can be measured using a colorimeter.

Moreover, as shown in FIG.4 (b), the temperature sensor 42 for detecting the temperature (water temperature) of the water accommodated in the predetermined container is provided, and this water temperature is predetermined temperature, for example, 30 degreeC or more. In such a case, it is preferable to discharge water from the first water discharge unit 14 ′, and to discharge water from the second water discharge unit 14 ″ when the water temperature is lower than a predetermined temperature, for example, lower than 30 ° C.
This is because the water discharger can be automatically selected at a predetermined temperature (water temperature 30 ° C.), and efficient antibacterial treatment according to the water temperature becomes possible.
Specifically, in the case of 30 ° C. or higher, since the antibacterial glass is easily dissolved, the water discharge portion where the antibacterial glass having a relatively low elution rate is used is used. Since it is hard to melt | dissolve, it is preferable to use the water discharge part which has arrange | positioned the antibacterial glass whose elution rate is comparatively quick.
Therefore, even when the water temperature is changed by such switching operation of the flow path, the concentration fluctuation of the antibacterial ions is reduced, and a substantially constant antibacterial ion concentration can be maintained.
In addition, the predetermined temperature which selects a water discharging part with a switching valve is not restricted to 30 degreeC, According to the use of a filtration apparatus, use environment, etc., it may raise to 40 degreeC, or may reduce to 10 degreeC. is there.

(3) Filter material Moreover, as the filter material 13 in the water discharging part 14 illustrated by FIG. 1 (a)-(b), it does not let floats, such as scale and hair, pass, but absorbs the water which absorbed water effectively. Although there is no particular limitation as long as it is present, usually a filter type or a filling type filter medium is preferably used.
Here, the filter-type filter material is preferably a material selected from the group consisting of a nonwoven fabric filter, a metal sintered filter, a ceramic sintered filter, a hollow fiber membrane filter, and an activated carbon filter.
The filling type filter material is selected from the group consisting of natural fibers, synthetic fibers, semi-synthetic fibers, activated carbon, resin-based filter media, filter stones, metal-based sintered materials, ceramic-based filter media, and shell fired bodies. Those are preferred.
This is because these filter media can efficiently remove not only fine suspended matters but also fine substances such as odor components and heavy metals. In addition, these filter media can be easily exchanged, so that maintainability can be improved.

In addition, it is preferable to make the average hole diameter of the filter as a filter material into the value within the range of 0.1-30 mm.
The reason for this is that if the average pore diameter is less than 0.1 mm, the pressure inside the filtration device increases, which may cause failure or clogging frequently. In addition, if the average pore diameter exceeds 30 mm, suspended matter or the like may not be captured or the filtration efficiency may be significantly reduced.
Therefore, the average pore diameter of the filter as a filter medium is more preferably set to a value within the range of 0.5 to 20 mm, and further preferably set to a value within the range of 1 to 10 mm.

(4) Shape of antibacterial glass Further, the shape of the antibacterial glass contained in the filter medium can be appropriately selected according to the mixed form with the filter medium, for example, powder, grain shape, rectangular shape or circle Examples include a plate shape such as a plate shape.
When the antibacterial glass is in a powder form, it is preferably used as a fiber or a filler of a resin-based filter material, or a sintered component of a metal-based sintered material or a ceramic-based filter agent.
This is because the antibacterial glass can be prevented from flowing out even under high water pressure conditions, and the elution amount of the antibacterial ions can be easily adjusted by selecting the type of the filter medium.

Moreover, when it is flat form, such as rectangular shape and disk shape, it is preferable to mix with a filter medium or to fill in the housing | casing which has a small hole.
The reason for this is that, since the outflow property is relatively small, the outflow property is small and the amount of antibacterial glass, the amount of antibacterial ion elution, etc. are easy even when mixed with a filter agent or filled in a housing. It is because it can be adjusted to.

Moreover, when glass shape is flat form, it is preferable to make a maximum diameter into the value within the range of 1-50 mm.
This is because if the maximum diameter is less than 1 mm, it may flow out or aggregate due to water pressure. Moreover, it is because manufacture will become difficult or a handleability may fall when the maximum diameter exceeds 50 mm.
Therefore, when the glass shape is a flat plate shape, the maximum diameter is more preferably set to a value within the range of 10 to 40 mm, and further preferably set to a value within the range of 15 to 30 mm.

(5) Types of antibacterial ions The antibacterial glass contained in the filter medium is an antibacterial glass that releases at least one type of antibacterial ions selected from the group consisting of silver ions, copper ions, and zinc ions as antibacterial ions. preferable.
This is because such antibacterial ions are highly safe for the human body and can exhibit an effective antibacterial effect against a wide variety of bacteria and fungi.
Moreover, it is more preferable that it is antibacterial glass which discharge | releases both silver ion and copper ion.
The reason for this is that a synergistic antibacterial effect of silver ions exhibiting effective antibacterial properties against bacteria and copper ions exhibiting effective antibacterial properties against algae and fungi can be exhibited. In particular, the antibacterial activity effective against Legionella symbiosis with algae can be imparted to filtered water.

(6) Elution amount of antibacterial ions The elution amount of silver ions in the antibacterial glass is preferably set to a value within the range of 0.01 to 100 mg / (g · 24 Hrs · 30 ° C.).
The reason for this is that when the elution amount of such silver ions is less than 0.01 mg / (g · 24 Hrs · 30 ° C.), the silver ions of a predetermined concentration are rapidly released when brought into direct contact with water. This is because it may be difficult to exert a predetermined antibacterial effect.
On the other hand, when the elution amount of such silver ions exceeds 100 mg / (g · 24 Hrs · 30 ° C.), it becomes difficult to release a predetermined concentration of silver ions over a long period of time, or handling becomes difficult or stable. This is because it becomes difficult to manufacture automatically.
Therefore, it is more preferable to set the elution amount of silver ions in the antibacterial glass to a value within the range of 0.05 to 50 mg / (g · 24 Hrs · 30 ° C.), and 0.10 to 40 mg / (g · 24 Hrs · 30 More preferably, the value is within the range of [° C.].

(7) Other inorganic antibacterial agents In addition to antibacterial glass, together with antibacterial glass, zeolite antibacterial agent, silica gel antibacterial agent, calcium phosphate antibacterial agent, zirconium phosphate antibacterial agent, silicate antibacterial agent It is preferably used in combination with at least one inorganic antibacterial agent selected from the group consisting of an agent, a titanium oxide antibacterial agent, a ceramic antibacterial agent and a whisker antibacterial agent.
This is because the antibacterial component concentration in the filtered water can be easily adjusted, and an effective antibacterial effect can be achieved against a wider variety of bacteria and fungi.

4). Flexible piping (1) material The flexible piping 17 illustrated in FIGS. 1 (a) to 1 (b) is appropriately selected from known materials such as resins and metals. The material is not particularly limited as long as the material has sufficient flexibility to be changed.
Specifically, it is preferably at least one resin selected from the group consisting of fluororesin, soft vinyl chloride, polypropylene, silicone rubber, and styrene butadiene rubber.
The reason for this is that, by using such a resin, a wide range of corrosion resistance and heat-resistant temperature as well as good flexibility, a predetermined flexibility can be obtained even under a wide range of water quality conditions and temperature conditions. This is because it can be maintained.
In addition, even if it is a hard material, sufficient flexibility can be obtained by providing variable structures, such as a bellows structure or an elbow structure, and it can be used as flexible piping.

(2) Shape As shown in FIGS. 5A to 5C, the flexible pipe preferably has at least one structure selected from the group consisting of a bellows structure, a swing-out structure, and a screwing structure.
The reason for this is that the length of the flexible pipe can be easily adjusted by such a configuration, but when it is contracted appropriately, it can be folded small.

5. Support part (1) material Although the support part 15 illustrated by Fig.1 (a)-(b) will not be specifically limited if it is a material provided with the intensity | strength required to support the water absorption part 12 and the water discharging part 14, Usually, it is preferably at least one resin selected from the group consisting of polyamide, hard vinyl chloride, fluororesin, polyphenylene sulfide, polyamideimide and polyimide.
This is because even if the filtered water is in a high temperature state or the component or water quality having an oxidizing or reducing action is acidic or alkaline, it is difficult to corrode and the service life can be extended.

(2) Shape Further, as shown in FIG. 6A, the shape of the support portion is preferably a pipe structure 15a that is also used as a pipe connecting the water absorption portion and the water discharge portion.
This is because the space can be further reduced and the movement of the filtering device is facilitated.
Moreover, as shown in FIGS. 6B to 6C, it is preferable that one or a plurality of support structures 15b and a tripod structure 15c are provided as separate bodies.
This is because the filtration device can be stably applied to the bottom surface of the predetermined container.

Further, as shown in FIGS. 7A to 7C, it is preferable to have at least one structure selected from the group consisting of the bellows structure 15d, the swinging structure 15e, and the screwing structure 15f.
This is because, with such a configuration, the support portion can be appropriately reduced and stored, and the usability of the filtration device can be further improved, and the overall size can be reduced.

6). Caster Structure As illustrated in FIGS. 1A to 1B, it is preferable to attach a caster structure 11 ′ to the bottom surface side of the pump unit 11 in the filtration device 10.
The reason for this is that by attaching such a caster structure, the filtration device can be easily and stably moved within the predetermined container.
The type of caster structure is not particularly limited, and examples thereof include a fixed wheel type, a free wheel type, a ball caster type, a surfaced ball caster type, and a twin wheel caster type.

7). Predetermined container (application target)
As illustrated in FIG. 1B, the predetermined container 19 to which the filtering device 10 is applied is not particularly limited, but for example, a bathtub, a hot spring, a pond, a water tank, a water tank, a fountain facility, a swimming Pool, amusement facility (attraction) attached pool, hydrophilic facilities attached pool, etc.
In addition, even if the predetermined container is a swimming pool or the like of about 25 m × 15 m, it is possible to selectively carry out filtration treatment on suspended matter and sediment, and usually filtration treatment for about 20 minutes to 120 minutes. It turns out that it is no good.

And among these predetermined containers, as illustrated in FIG. 1B, it is preferable to target the bathtub 19.
This is because the bath water can be filtered efficiently and is easy to use, and the predetermined antibacterial treatment is also carried out, so that it can be easily used for secondary use such as washing water. It is.

  Hereinafter, based on an Example, this invention is demonstrated in detail. Needless to say, the following description exemplifies the present invention, and the scope of the present invention is not limited to the following description without any particular reason.

Finally, the second water discharger and the support are connected via a soft vinyl pipe (outer diameter: 50 mm, inner diameter: 40 mm) as a flexible pipe. It was set as the filtration apparatus.

2. Evaluation of filtration device The obtained filtration device was evaluated as a throw-type filtration device.
That is, the obtained filtration device is put into a bathtub (outside dimensions: 1000 × 700 × 590 (mm), inner dimensions: 875 × 590 × 540 (mm), full water volume: 220 liters), and vertically It installed so that it might become. And at the time of a filtration process, after arrange | positioning so that two water absorption parts in a filtration apparatus may be located in the bottom of a bathtub, the following evaluation was implemented.

○: Almost no odor is felt, and almost no discoloration in bath water is observed.
(Triangle | delta): A foul odor is felt a little and discoloration in bath water is seen a little.
X: A strong odor is felt and discoloration in the bath water is noticeable.

[Example 2]
The filtration apparatus was evaluated in the same manner as in Example 1 except that the operation time (filtration treatment time) of the filtration apparatus was 60 minutes.
In addition, compared with Example 1, in Example 2, it was confirmed that evaluation improves filterability evaluation 1 and 2 and antibacterial evaluation, respectively.

[Example 3]
The filtration device was evaluated in the same manner as in Example 1 except that the operation time (filtration treatment time) of the filtration device was 120 minutes.
In addition, compared with Example 1, in Example 3, it was confirmed that evaluation improves each about filterability evaluation 1 and 2, and antibacterial evaluation.

[Example 4]
Antibacterial glass having an Ag release rate of 0.10 mg / (g · 24Hrs · 30 ° C.) in the first water discharge portion, and an Ag release rate of 1.5 mg / (g · 24Hrs · 30 in the second water discharge portion. When the water temperature is 30 ° C. or higher, water is discharged from the first water discharge portion. When the water temperature is lower than 30 ° C., water is discharged from the second water discharge portion. A filtration device was prepared and evaluated in the same manner as in Example 1 except that a temperature sensor for providing the temperature was provided.
In addition, compared with Example 1, in Example 4, it was confirmed that evaluation improves filterability evaluation 1 and 2 and antibacterial evaluation, respectively.
The reason why the evaluation in the filterability evaluations 1 and 2 is improved is that in Example 5, unlike Example 1, there is almost no slime in the flow path of the filtration device, and the initial water absorption force is increased. This is thought to be due to the fact that it could be maintained for a long time.
Further, it was separately confirmed that in Example 4, the use time of the antibacterial glass was remarkably increased as compared with Example 1, and the variation in the amount of silver ions in the bath water was also reduced.

[Comparative Example 1]
A filtration device was prepared and evaluated in the same manner as in Example 1 except that the antibacterial glass was not included in the filter material in the water discharge part of Example 1 at all.
In addition, compared with Example 1, in Comparative Example 1, it is considered that the filter medium does not contain antibacterial glass, but the antibacterial evaluation as well as the filterability of the floating material on the surface of the bath water ( It has been found that the filterability evaluation 1) also decreases.

According to the present invention, the filter device is arranged independently from a bath or the like, and provided with a water absorption part that can move in an arbitrary direction, so that it is easy to downsize, is easy to use, and is efficiently used. Can be filtered and antibacterial treated.
