Yes.
- the cylindrical portion 13a is formed so as to protrude from the inner bottom surface of the case main body 14a with a predetermined protruding dimension A, particularly on the inner side, and protrudes downward through the bottom portion on the outer side. Therefore, the upper end portion of the cylindrical portion 13a having the protruding dimension A becomes the upper end opening surface of the outflow port 13, and indicates a water level that allows the water in the filtration case 14 to flow out.
- annular pedestal 18 is formed at the bottom of the case body 14a so as to protrude from the outer periphery of the cylindrical portion 13a having the protruding dimension A.
- the projecting dimension B of the pedestal 18 corresponds to a height dimension projecting upward from the reference surface (inner bottom surface) common to the projecting dimension A, but is smaller than the projecting dimension A (projecting dimension A> B).
- the upper end portion of the base 18 is lower than the upper end opening surface of the tubular portion 13a.
- the annular pedestal 18 is formed on the outer periphery of the cylindrical portion 13a as the outflow port 13, two annular recesses are formed at the bottom of the case body 14a as the filtration case 14.
- the first recess 19 formed around the cylindrical portion 13a on the inner side has a wider and larger volume than the second recess 20 formed around the pedestal 18 on the outer side.
- the first recess 19 has a size that can accommodate a storage case 22 that stores a predetermined amount of an antibacterial agent 21 to be described later.
- the inner volume of the recess 19 can be easily secured by, for example, the position where the pedestal 18 is formed, and in the present embodiment, the pedestal 18 is set to have substantially the same diameter as a cylindrical core member 24 described later.
- the lower end portion of the cylindrical portion 13a projecting downward from the filtration case 14 is fitted to the water supply port 8 of the washing machine 1 shown in FIG. 2 via a packing (not shown), and is connected in a watertight and detachable manner.
- a water supply path for supplying water to a washing tub (not shown) inside the washing machine 1 is formed.
- the inlet 12 of the filtration case 14 is formed by a cylindrical cylindrical portion 12a extending in the vertical direction at the center of the cap 14b, and the cylindrical portion 12a protrudes into and out of the cap 14b. At the same time, it is configured to protrude greatly to the outside on the upper side.
- the upper end portion of the cylindrical portion 12a protruding to the outside is connected to the water supply hose 10 shown in FIG. 2 by fitting, and then connected to a tap faucet 9 to form a water supply path from a water source.
- the filtration device 2 is provided in a water supply path from the water source to the washing machine 1 and is set in a vertically oriented state with the inlet 12 as the upper position and the outlet 13 as the lower position.
- the configuration of the filter medium 15 provided in the filter case 14 and the core unit 23 that holds the filter medium 15 in a predetermined position will be described.
- the configuration of the core unit 23 will be described.
- the core unit 23 has a cylindrical shape with the upper surface closed and the lower surface open, and has a predetermined gap as a water passage between the inner peripheral surface of the filtration case 14. Is contained.
- the core unit 23 is integrally formed of, for example, polypropylene resin, and includes a cylindrical core member 24 and a disc-shaped holding plate 25 whose upper surface is closed.
- the holding plate 25 is located at the upper part in the filter case 14 and is disposed so as to face the inlet 12 so that the upper surface of the holding plate 25 is orthogonal to the inlet 12, and therefore water from the inlet 12 shown by an arrow in FIG. It is in an arrangement state orthogonal to the inflow direction.
- the holding plate 25 is integrally provided with a plurality of (for example, four) protrusions 26 extending radially from the center of the flat upper surface, as particularly shown in FIG.
- the protrusions 26 are formed in a radial shape except for a central portion corresponding to the opening area of the inflow port 12, and are formed so as to protrude vertically.
- the holding plate 25 and the radial protrusion 26 receive the water flowing in from the inflow port 12 by the holding plate 25 and bend the water flow at right angles to flow in the outer peripheral direction, although the detailed description of the operation will be described later.
- the radial protrusions 26 provide a rectifying action for evenly distributing and flowing water. Therefore, the protrusion 26 is not limited to a plate shape, and may be implemented with various modifications, such as a cross-sectional mountain shape, or a bar-shaped protrusion group instead of a continuous protrusion shape. .
- the cylindrical core member 24 is formed with, for example, a plurality of lattice-shaped through holes 24a over almost the entire surface of the peripheral wall, so that water permeability inside and outside is good.
- the shape of each through hole 24a may be a shape that facilitates integral molding of the holding plate 25 and the core member 24, and thus may be a circular through hole, and does not necessarily have to be the same shape.
- the core member 24 has a cylindrical shape slightly smaller in diameter than the holding plate 25, and the filter medium 15 is wound and held on the outer peripheral surface thereof.
- the filter medium 15 will be described in detail.
- any flexible cloth such as old clothes or unnecessary clothes can be used.
- a white nonwoven fabric is formed into a sheet. The cut out is formed in a cylindrical shape as shown in FIG. That is, both ends of the sheet shape are stitched together to obtain a cylindrical filter medium 15 substantially equal to the diameter of the core member 24.
- the filter medium 15 is held without being easily dropped by being wound so as to be fitted into the outer peripheral surface of the core member 24 using its flexibility and elasticity.
- the lower end portion of the filter medium 15 is set to be slightly shorter than the lower end portion of the core member 24 as shown in FIG. The entire surface is in close contact with the outer peripheral surface of the core member 24.
- the core unit 23 holding the filter medium 15 is accommodated in a predetermined position in the filter case 14. That is, the core unit 23 is accommodated from the core member 24 side in the case main body 14a with the cap 14b removed.
- the core member 24 is formed at substantially the same radial position as the annular pedestal 18. For this reason, while the lower end part of the core member 24 contact
- the upper end surface of the pedestal 18 since the lower end portion of the core member 24 protrudes downward from the filter medium 15, the upper end surface of the pedestal 18 has a different length so that it can be brought into contact with and received by the lower end portions having different lengths. End surfaces 18a and 18b having steps corresponding to the length are formed. Therefore, the lower end portion of the core member 24 abuts on the inner lower end surface 18a, and the lower end portion of the filter medium 15 abuts on the outer high end surface 18b corresponding to the upper end surface in the protruding dimension B, and is supported. At this time, the outer periphery of the lower end portion of the core member 24 is held at a predetermined position by restricting the lateral movement at the step portion.
- the filter medium 15 supported at the lower end is prevented from sliding downward due to weight or the like, and is held at a predetermined position.
- the core unit 23 including the filter medium 15 is set at a predetermined position in the filter case 14 by coupling the cap 14b to the case body 14a.
- the outer peripheral surface of the core unit 23 accommodated in this way is arranged with a predetermined gap from the upper wall surface and the side wall surface in the filtration case 14, and the gap is the water at the time of water supply. Flows in the direction of the arrow shown in the figure (details will be described later).
- the antibacterial agent 21 has a tablet shape formed in an appropriate polygonal shape (polyhedron) as shown in the figure, and elutes antibacterial components when immersed in water. In other words, it has a solubilized solubility in water and is composed of a metal element having antibacterial properties and phosphate glass. Specifically, for example, about 3 weight percent silver oxide, about 27 weight percent zinc oxide, about 1 weight percent cobalt oxide, and about 1 weight percent calcium phosphate are suitable for eluting the desired antimicrobial component in this embodiment. It consists of 69 weight percent.
- silver oxide elutes silver ions having antibacterial properties in water as an antibacterial component and imparts an antibacterial effect to the laundry being washed as will be described later. If the content of the silver oxide is 0.1% by weight or less, a substantial antibacterial action cannot be obtained, and if it is 5% by weight or more, the color is easily changed to brown by light and the production cost is increased. Therefore, the silver oxide content is preferably 0.1 to 5 weight percent.
- Zinc oxide is mainly responsible for preventing browning of silver oxide.
- the antibacterial action is recognized also to the zinc ion eluted from this zinc oxide, although not as much as a silver ion, it also functions as an antibacterial component.
- zinc oxide may be slightly discolored, the content is preferably 50% by weight or less.
- Cobalt oxide is added as a metal oxide for coloring the antibacterial agent 21 itself in blue, and the antibacterial agent 21 can be colored in vivid blue even with a very small content. Although this will be described in detail later, this coloring is effective for visually confirming the presence or absence and the remaining amount of the antibacterial agent 21.
- the phosphoric acid-based glass mainly contains a phosphoric acid component (P205) as a soluble glass, and this phosphoric acid component (P205) maintains the transparency of the glass or allows silver ions to be contained in washing water. Has the effect of slow dissolution. However, if the concentration is less than 10 percent by weight, the mechanical strength may not be maintained, while if it exceeds 80 percent by weight, the mechanical strength may be reduced. Therefore, the content of the phosphoric acid component (P205) is preferably 10 to 80 weight percent of the whole antibacterial agent 21, and optimally 30 to 70 weight percent.
- this phosphoric acid component dissolves in water, it has a chelate structure (Ca2P6018 2 ⁇ , Mg2P6018 2 ⁇ ) with respect to calcium and magnesium in tap water which is washing water, so that the water solubility of calcium is increased and the interface is increased.
- the effect of the activator can be enhanced to improve the cleaning performance.
- the phosphate component is eluted as an anion
- the eluted silver ion has an effective antibacterial effect without generating the above-mentioned hardly soluble salt by the phosphate component.
- the state can be stably maintained, and the antibacterial action can be effectively maintained.
- the housing case 22 includes a cylindrical container portion 22a having a bottomed container shape and a flat lid portion 22b that can open and close the upper surface opening of the container portion 22a.
- a part of the peripheral end portion of the lid portion 22b is integrally formed in a state where it is connected to the upper end portion of the container portion 22a, and the connecting portion is made into a thin-walled portion or further cut.
- a hinge portion 22c that allows the lid portion 22b to rotate (in the direction of the arrow in FIG. 4) is formed, so that the lid portion 22b can be opened and closed with respect to the container portion 22a.
- the container portion 22a is provided with a cylindrical inner tube portion 27 standing from the bottom side at the center so as to form a hollow container, and horizontally at the upper (opening) side at the upper end portion.
- a flange portion 27a extending in the direction is formed.
- many water flow holes 28 are formed in the outer peripheral side wall of the container part 22a. The large number of water passage holes 28 allow the antibacterial component of the antibacterial agent 21 accommodated therein to flow out of the container and allows the state of accommodation such as the remaining amount of the antibacterial agent 21 to be easily visually observed from the outside.
- the opening shape is also taken into consideration.
- the specific shape of the lid portion 22b is formed with an opening 29 having approximately the same size as the diameter of the inner cylinder portion 27 and a large number of water passage holes 30 at the center.
- engaging claw portions 31 that can be elastically deformed are projected at three locations on the outer peripheral end other than the hinge portion 22c.
- This engagement claw portion 31 constitutes an engagement means for holding the lid portion 22b in a closed state.
- the engagement claw portion 31 has three engagement claw portions 31 corresponding to the engagement claw portion 31 at three locations on the outer peripheral upper end portion on the container portion 22a side.
- An engaged portion 32 that elastically hooks the pawl portion 31 is formed.
- the engaging claw part 31 is elastically deformed in the radial direction to constitute an engaging means that can be engaged and disengaged.
- the storage case 22 in which the antibacterial agent 21 is stored and the lid 22b is closed in the container 22a has a donut shape with a hole in the center.
- the housing case 22 housed in the first recess 19 in the inner bottom portion of the filtration case 14 is in a state where the inner tubular portion 27 is fitted to the tubular portion 13a of the outlet 13 and the tubular portion 13a.
- the flange portion 27a is latched to the upper end of each of the two, and is held and held in a predetermined position. Therefore, the filtration device 2 having a so-called antibacterial function is configured in which the antibacterial agent 21 having a slow solubility in water is accommodated in the filter case 14 and the antibacterial component can be eluted.
- the filtering device 2 is provided in the water supply path to the washing machine 1 (see FIG. 2), and the tap water reaches the filtering device 2 as the faucet 9 is opened. As shown in FIG. 1, the water that has reached the filtration device 2 flows into the filtration case 14 from the inlet 12 at the top of the filtration case 14, and flows down in the direction of the arrow shown in the figure.
- the water collides with the holding plate 25 of the core unit 23 and the flow is redirected in a right angle direction.
- the water is guided by the radially extending projections 26 provided on the upper surface of the holding plate 25 and is subjected to a rectifying action that is evenly distributed, so that water does not generate turbulent flow such as unnecessary vortex flow in the outer circumferential direction. It efficiently flows down to the outer peripheral side in the filtration case 14 while equalizing the flow and amount of water. Therefore, water can pass under almost the same conditions around the entire surface of the filter medium 15, and at that time, impurities such as iron rust are effectively captured and filtered.
- the purified water that has passed through the filter medium 15 flows inward through the through holes 24a of the core member 24, reaches the water level that exceeds the upper end opening of the outlet 13, and can be discharged to the outside from the outlet 13. That is, it is supplied to the washing tub from the water supply port 8 of the washing machine 1. Since the amount of water and water pressure on the supply side with tap water are superior, the water supply path including the filtering device 2 is filled with water as the water supply operation is continued, and the water passing through the filter medium 15 is smoothly discharged from the outlet 13. Is continuously discharged.
- the residual water amount is from the bottom to the outlet 13.
- An amount corresponding to the space between the upper end opening surface is stored, and in this embodiment, corresponds to a combination of the first recess 19 and the second recess 20.
- the antibacterial function of the antibacterial agent 21 will be described.
- the antibacterial agent 21 is in the housing case 22 and is a first recess around the outlet 13 that is the bottom of the filtration case 14. 19. Therefore, when the above-mentioned water supply operation is the first time, since the remaining water is not yet stored in the first recess 19 or the like, the water that has passed through the filter medium 15 by the water supply operation has not been confirmed. It contacts the antibacterial agent 21 for the first time by flowing into 19. The water in the first recess 19 tends to stay slightly because there is no outlet at the lower part, and becomes a slow flow (overflow). Subsequently, along with the water flowing into the filtration case 14 It flows out from the outlet 13. For this reason, the water in the first recess 19 flows out while being replaced with new water, and the water supply operation to the washing machine 1 (washing tub) is executed.
- the antibacterial component can be eluted.
- a stable antibacterial effect can be obtained even when a desired antibacterial effect is obtained in a water supply operation in which the contact time with water is short, or even if the water supply operation (time) is changed according to the amount of laundry. Therefore, it is difficult to adjust the solubility.
- an antibacterial agent having improved solubility for this purpose has a drawback that it is likely to be dissolved and consumed quickly, and a large amount of the antibacterial agent is used.
- the antibacterial agent 21 in the present embodiment gradually dissolves the antibacterial component using the residual water generated after the first water supply operation, so that the antibacterial component reaches an appropriate concentration during the next water supply operation of the laundry. Can be supplied into the washing tub together with the water supply.
- the amount of water that elutes the antibacterial component is set to a constant residual water amount that combines the first recess 19 and the second recess 20 as described above.
- the composition component has a slow solubility so that a desired antibacterial effect can be obtained when washing the next day.
- the antibacterial agent 21 can be prevented from being dissolved and consumed at an early stage.
- the water supply operation is performed about 2 to 4 times including the rinsing in one washing operation, but the early dissolution of the antibacterial agent 21 can be prevented and the contact time with the remaining water can be reduced. Even if there is an error (variation), the early dissolution of the antibacterial agent 21 can still be suppressed.
- the amount of residual water is almost constant, as the eluted antibacterial component becomes saturated, it can be used for a long period of time, such as preventing further dissolution, and the replenishment work of the antibacterial agent 21 is also reduced. It is possible to obtain a desired antibacterial effect which is stable for laundry.
- the pedestal 18 on the second recess 20 side has a low protruding height as indicated by a protruding dimension B.
- the upper end of the pedestal 18 supports the core member 24 and the lower end of the filter medium 15, but the support structure does not have a special watertight structure and the filter medium 15 is a material that allows water to penetrate.
- the water level S exceeds the pedestal 18 and becomes the same water level in the first recess 19 and the second recess 20, and the lower end of the filter medium 15 is immersed in the remaining water (see FIG. 1).
- the antibacterial effect on the laundry by the antibacterial agent 21 that contacts the water during the water supply operation for the first time is not sufficient.
- the antibacterial agent 21 soaked in the remaining water in 14 starts from a state in which a desired antibacterial component is eluted under a predetermined amount of water based on the residual water level S.
- the antibacterial agent 21 is supplied with the water supply to the washing tub in the water supply operation of the first washing operation, and the antibacterial component is sufficiently imparted to the laundry through the washing operation.
- this washing water is drained and water supply and rinsing are newly performed, the antibacterial effect imparted to the laundry can be sufficiently maintained.
- the residual water level S in the filter case 14 keeps the lower end portion of the filter medium 15 in an immersed state, so that the antibacterial components eluted in the water gradually permeate from the lower end portion of the filter medium 15 to the upper portion. Therefore, the residual water containing the antibacterial component stored until the next washing operation is performed can be expected to have an antibacterial action of the filter medium 15 itself due to permeation into the filter medium 15.
- the washing water which is the washing water supplied from the water source, is a clean water in which impurities such as iron rust are filtered and removed by the original filtration function of the filtration device 2 and is provided in the filtration device 2.
- impurities such as iron rust are filtered and removed by the original filtration function of the filtration device 2 and is provided in the filtration device 2.
- water that imparts an antibacterial effect to the laundry due to the antibacterial function it can be supplied to the washing machine 1 and a clean and safe laundry washing effect can be expected.
- the filter medium 15 As described above, it is necessary to check the status of the filter medium 15 that captures impurities such as iron rust and the remaining amount of the antibacterial agent 21 that is a consumable item through maintenance and inspection while the filter device 2 is used.
- the filter medium 15 since at least the case main body 14a is made of a transparent resin, the clogged state due to iron rust (red rust) on the filter medium 15 can be visually discriminated from the outside based on the redness of the dirt, and the filter medium 15 It is possible to easily know the appropriate replacement time and cleaning time. Therefore, the filter medium 15 is effective in that it can be easily determined that a white material is adopted.
- the antibacterial agent 21 is also housed in the first recess 19 which is the bottom of the transparent resin case body 14a. Since the storage case 22 for storing the antibacterial agent 21 is provided with a large number of water passage holes 28 on the outer peripheral side thereof, the remaining amount of the antibacterial agent 21 inside can be visually observed from the water passage hole 28, and thus transparent filtration It can also be confirmed visually from the outside of the case 14. In this case, since the antibacterial agent 21 is vividly colored blue with cobalt oxide, the remaining amount can be visually recognized more easily and accurately. Note that the housing case 22 can be visually recognized more easily if it is made of a transparent resin in the same manner as the case body 14a.
- the filter device 2 When the filter medium 15 is replaced or the antibacterial agent 21 is replenished based on the inspection result, for example, the filter device 2 is separated from the water supply path such as the water supply hose 10 connected to the faucet 9.
- the filtration device 2 can be disassembled into parts shown in FIG. That is, the filtration case 14 can be easily separated by simply unscrewing the screw connection (male and male screw portions 16a and 16b) between the case main body 14a and the cap 14b, and the core unit 23 accommodated therein can be taken out. Of course, the filter medium 15 attached to this can also be taken out and separated. Therefore, when the filter medium 15 is replaced with a new one, or when the filter medium 15 is washed to eliminate clogging and reused, it can be dealt with at this disassembled stage.
- the housing case 22 when replenishing the antibacterial agent 21, after taking out the core unit 23, the housing case 22 housed and arranged below it is taken out.
- the housing case 22 is configured such that the lid portion 22b can be opened and closed with respect to the container portion 22a via a hinge portion 22c.
- the elastic engagement with the engaging portion 32 can be easily detached by elastically deforming the engaging claw portion 31, and the lid portion 22b can be opened. Therefore, a new antibacterial agent is replenished, and the accommodation case 22 in which the lid portion 22b is engaged and held again is accommodated in the first recess 19 in the inner bottom portion of the case body 14a.
- the donut-shaped accommodation case 22 can be accommodated and arranged at a predetermined position by inserting the cylindrical portion 13a forming the outlet 13 as a positioning guide.
- the assembly work after the disassembly may be performed in the reverse order, that is, the housing case 22 housing the antibacterial agent 21 is housed in the first recess 19 at the bottom of the case body 14a and the upper part thereof is covered.
- the core unit 23 equipped with the filter medium 15 is accommodated. In this case, it is only necessary to place and support the lower end portions of the core member 24 and the filter medium 15 on the pedestal 18.
- a filter case 14 is constructed by screwing the cap 14b to the case body 14a in this state via the packing 17 (male and female screw portions 16a and 16b), and the assembly as the filter device 2 is completed. May be set in the water supply path such as the water supply hose 10.
- a filtration device 2 is provided in the water supply path from the external water source to the washing machine 1, and a water passage between the inlet 12 and the outlet 13 provided at the upper and lower portions of the filtration case 14 constituting the filtration device 2 is partitioned.
- water purified by filtering impurities such as iron rust (red rust) in water is supplied to the washing tub so that it can be washed. Therefore, it is possible to eliminate the harmful effects such as discoloration of laundry due to iron rust.
- the filter case 14 containing the filter medium 15 is made of a transparent resin so that the filter case 14 can be seen through, the clogged state of the filter medium 15 can be visually observed from the outside, and can be easily discriminated from, for example, the degree of dirt that turns red by iron rust. As a result, it is easy to use and maintenance can be performed easily even in ordinary households.

Description
本発明の実施形態は、濾過機能のほかに抗菌機能を備えた洗浄機器用の濾過装置に関する。
The embodiment of the present invention relates to a filtration device for a cleaning device having an antibacterial function in addition to a filtration function.
従来、洗浄機器として例えば家庭用の洗濯機では、一般的に外部の水源として水道水を利用しているが、その水道水にあっても不純物が混入する場合がある。例えば、水道の配管や貯水タンクなどの給水設備の老朽化に伴い鉄錆(赤錆)が発生することがあり、これが混入して水道水が赤色に濁る場合(赤水)がある。
Conventionally, for example, a domestic washing machine as a cleaning device generally uses tap water as an external water source, but impurities may be mixed even in the tap water. For example, iron rust (red rust) may occur with the aging of water supply facilities such as water pipes and water storage tanks, and tap water may become muddy red (red water).
その他、節水のために外部水源として風呂水などの貯水源を利用すべく、給水ポンプを利用して給水し洗濯水として活用する場合も多い。このような、鉄錆等の不純物を含む水の使用は被洗浄物たる洗濯物の汚れや変色(黄ばみ)、更には洗浄用の槽体や通水経路に発錆を誘発するなどのおそれがあり、しかも電磁式の給水弁を備えた洗濯機では、給水弁内部に堆積して動作不良を招くおそれもある。
In addition, in order to save water, there are many cases where water is supplied using a water supply pump and used as washing water in order to use a water storage source such as bath water as an external water source. The use of water containing impurities such as iron rust may cause dirt and discoloration (yellowing) of the laundry that is the object to be cleaned, and also induce rusting in the washing tank and water passage. In addition, in a washing machine equipped with an electromagnetic water supply valve, there is a possibility that it will accumulate inside the water supply valve and cause malfunction.
そこで、このような問題に対処するため、洗濯機への給水経路中に濾過装置を設けて供給水を濾過し、鉄錆などの不純物を除去することが提案されている(例えば、特許文献1参照)。
Therefore, in order to deal with such problems, it has been proposed to provide a filtration device in the water supply path to the washing machine to filter the supplied water to remove impurities such as iron rust (for example, Patent Document 1). reference).
一方、衣類の着用時に付着した雑菌類は、洗濯しても完全に除去できない場合が多く、その雑菌が洗濯後に繁殖して臭気を発生するおそれがあった。そこで、抗菌剤供給手段を備えた洗濯機が提案されており、例えば洗濯槽内に徐溶性の抗菌剤を収容して抗菌成分を溶出させ、洗濯物に抗菌効果を施すようにした、所謂抗菌機能を備えたものである(例えば、特許文献2参照)。
On the other hand, various germs attached when wearing clothes cannot be completely removed even after washing, and there is a possibility that the germs propagate after washing and generate odor. Therefore, a washing machine equipped with an antibacterial agent supply means has been proposed. For example, a so-called antibacterial agent in which a slowly dissolving antibacterial agent is contained in a washing tub and an antibacterial component is eluted to impart an antibacterial effect to the laundry. It has a function (see, for example, Patent Document 2).
しかも近年、安全性や衛生的で清潔志向の高まりから、上記鉄錆などの不純物の除去とともに洗濯物への十分な抗菌効果を得たいとするニーズがあるが、一般家庭での保守点検などのメンテナンスが面倒となったり、抗菌剤供給手段を具備しない既存の洗濯機に装備することが困難などの問題を有していた。
Moreover, in recent years, there has been a need to obtain sufficient antibacterial effects on laundry as well as removal of impurities such as iron rust due to the increase in safety and hygiene and cleanliness. There are problems such as troublesome maintenance and difficulty in installing in an existing washing machine that does not have an antibacterial agent supply means.
そこで、鉄錆などの不純物を濾過する濾過装置に、被洗浄物に抗菌効果が付与できる抗菌機能を具備し、安全で清潔な洗浄水が得られるとともに、メンテナンスも容易で、既存の洗浄機器にも装備することが可能な洗浄機器用の濾過装置を提供することにある。
Therefore, the filtration device that filters impurities such as iron rust has an antibacterial function that can give antibacterial effect to the object to be cleaned, and safe and clean washing water is obtained, and maintenance is easy. It is another object of the present invention to provide a filtering device for a cleaning device that can be equipped with a cleaning device.

前記濾過ケース内に水に対する徐溶性を有する抗菌剤を収容し、不純物を濾過し抗菌成分を溶出した洗浄水を供給する。 According to the filtering device for a cleaning device of the present embodiment, the filtering device is provided in the water supply path, and has a hollow having an inflow port through which water flows in at one end and an outflow port through which water flows out at the other end. In a container-like filtration case, a filter medium for filtering impurities contained in water is provided so as to partition between the inflow port and the outflow port,
An antibacterial agent having a slow solubility in water is accommodated in the filter case, and cleaning water is supplied by filtering impurities and eluting antibacterial components.

2 is an external perspective view showing a use state (or a usable set state) of the
上記操作パネル7には、水道水などの外部水源から図示しない洗濯槽に給水するための円筒状の給水口8を、ほぼ真っ直ぐに上方に突設している。この給水口8には、外部水源からの水の供給と遮断を切り替える蛇口9、可撓性の給水ホース10、および詳細は後述する水中の不純物を濾過する濾過装置2を経て水密に連通接続され、該濾過装置2は所謂外部水源から給水口8(洗濯機1)に至る給水経路中に設けられた構成としている。なお、上記給水ホース10の接続部位には、必要に応じホース止めクリップ11を採用してホース抜け止め用として緊締する。
The operation panel 7 is provided with a cylindrical water supply port 8 for supplying water from an external water source such as tap water to a washing tub (not shown) almost straight upward. The water supply port 8 is connected in a watertight manner through a faucet 9 that switches between supply and shut-off of water from an external water source, a flexible water supply hose 10, and a filter device 2 that filters impurities in water, which will be described in detail later. The filtration device 2 is configured in a water supply path from a so-called external water source to the water supply port 8 (washing machine 1). In addition, the hose stop clip 11 is employ | adopted for the connection site | part of the said water supply hose 10 as needed, and it tightens for the hose removal prevention.
そして図1および図3は、上記濾過装置2の具体的構成を示す縦断面図および分解斜視図である。以下、濾過装置2の具体的構成につき説明する。濾過装置2は、大略的には前記給水経路中に設けられ、一端たる上端部に水が流入する流入口12を有し、他端たる下端部に水が流出する流出口13を有する中空容器状の濾過ケース14と、この濾過ケース14内にあって前記流入口12と前記流出口13との間の通水路を仕切る位置に設けられた濾材15とを具備した構成からなり、前記濾材15は水に含まれる鉄錆などの不純物を捕獲除去できる濾過機能を有する。
1 and 3 are a longitudinal sectional view and an exploded perspective view showing a specific configuration of the filtration device 2. Hereinafter, a specific configuration of the filtration device 2 will be described. The filtration device 2 is generally provided in the water supply path, and has an inflow port 12 through which water flows into an upper end portion as one end and an outflow port 13 through which water flows out into a lower end portion as the other end. A filter case 14 and a filter medium 15 provided in the filter case 14 at a position that partitions the water passage between the inlet 12 and the outlet 13. Has a filtration function capable of capturing and removing impurities such as iron rust contained in water.
具体的には、まず濾過ケース14は、上面を開放した有底円筒状のケース本体14aと、このケース本体14aの上面を覆う円盤状のキャップ14bとから構成され、いずれも樹脂成形され少なくともケース本体14aは透明な樹脂材料(例えば、アクリルニトリルブタジエンスチレン樹脂、アクリルニトリルスチレン樹脂、ポリカーボネイト樹脂、アクリル樹脂など)で形成され、内部を透視可能としている。
Specifically, first, the filtration case 14 includes a bottomed cylindrical case main body 14a having an open upper surface and a disk-shaped cap 14b covering the upper surface of the case main body 14a. The main body 14a is formed of a transparent resin material (for example, acrylonitrile butadiene styrene resin, acrylonitrile styrene resin, polycarbonate resin, acrylic resin, etc.), and the inside can be seen through.
このケース本体14aには、上記キャップ14bが着脱可能に結合されている。すなわち、上記ケース本体14aの上部外周側には、雄ねじ部16aが形成される。一方、キャップ14aの内周側には雌ねじ部16bが形成される。これらねじ部16a,16bが噛合するねじ結合によりキャップ14bは着脱可能に被着されている。なお、ねじ結合される両者間には、ゴムなどのパッキン17が介在され、水密に結合され着脱可能とする濾過ケース14が構成される。
The cap body 14a is detachably coupled to the case body 14a. That is, a male screw portion 16a is formed on the upper outer peripheral side of the case body 14a. On the other hand, an internal thread portion 16b is formed on the inner peripheral side of the cap 14a. The cap 14b is detachably attached by screw connection in which the screw portions 16a and 16b are engaged. In addition, a packing 17 made of rubber or the like is interposed between the two screw-coupled to form a filtration case 14 that is water-tightly coupled and detachable.
そして、濾過ケース14の前記流出口13は、ケース本体14aの下部たる底部中央部に円筒状に突設した筒状部13aにてケース本体14aの内外を上下方向に連通した状態で形成されている。この筒状部13aは、特に内方側にあってはケース本体14aの内底面から所定の突出寸法A突出して形成され、外方側では底部を貫通して下方にも突出している。従って、突出寸法Aを有する筒状部13aの上端部が流出口13の上端開口面となり、濾過ケース14内の水が外部に流出可能とする水位を示すことになる。
And the said outflow port 13 of the filtration case 14 is formed in the state which connected the inside and outside of the case main body 14a to the up-down direction in the cylindrical part 13a protrudingly provided cylindrically by the bottom center part which is the lower part of the case main body 14a. Yes. The cylindrical portion 13a is formed so as to protrude from the inner bottom surface of the case main body 14a with a predetermined protruding dimension A, particularly on the inner side, and protrudes downward through the bottom portion on the outer side. Therefore, the upper end portion of the cylindrical portion 13a having the protruding dimension A becomes the upper end opening surface of the outflow port 13, and indicates a water level that allows the water in the filtration case 14 to flow out.
また、ケース本体14aの底部において、突出寸法Aを有する筒状部13aの外周囲に間隔を置いて環状の台座18を突出形成している。この台座18の突出寸法Bは、突出寸法Aと共通の基準面(内底面)から上方に突出する高さ寸法に相当するものであるが、突出寸法Aより小さく(突出寸法A>B)、つまり筒状部13aの上端開口面より台座18の上端部が低い突出形状としている。
Further, an annular pedestal 18 is formed at the bottom of the case body 14a so as to protrude from the outer periphery of the cylindrical portion 13a having the protruding dimension A. The projecting dimension B of the pedestal 18 corresponds to a height dimension projecting upward from the reference surface (inner bottom surface) common to the projecting dimension A, but is smaller than the projecting dimension A (projecting dimension A> B). In other words, the upper end portion of the base 18 is lower than the upper end opening surface of the tubular portion 13a.
この環状の台座18を流出口13たる筒状部13aの外周囲に形成したことにより、濾過ケース14たるケース本体14aの底部には、環状の凹所が2箇所に形成されている。そのうち、内方側で筒状部13a周りに形成された第1の凹所19は、その外方側で台座18周りに形成された第2の凹所20より幅広で大きな容積を有している。特に、第1の凹所19は、後述する所定量の抗菌剤21を収納した収容ケース22を収容できる大きさを有している。この凹所19の内容積は、例えば台座18の形成位置により容易に確保できるとともに、本実施形態では台座18は後述する円筒状のコア部材24とほぼ同一の径寸法に設定されている。
Since the annular pedestal 18 is formed on the outer periphery of the cylindrical portion 13a as the outflow port 13, two annular recesses are formed at the bottom of the case body 14a as the filtration case 14. Among them, the first recess 19 formed around the cylindrical portion 13a on the inner side has a wider and larger volume than the second recess 20 formed around the pedestal 18 on the outer side. Yes. In particular, the first recess 19 has a size that can accommodate a storage case 22 that stores a predetermined amount of an antibacterial agent 21 to be described later. The inner volume of the recess 19 can be easily secured by, for example, the position where the pedestal 18 is formed, and in the present embodiment, the pedestal 18 is set to have substantially the same diameter as a cylindrical core member 24 described later.
なお、この濾過ケース14の下方に突出した筒状部13aの下端部は、図2に示す洗濯機1の給水口8と図示しないパッキンを介して嵌合し、もって水密で着脱可能に連結され洗濯機1内部の洗濯槽(図示せず)に水を供給する給水経路を形成している。
The lower end portion of the cylindrical portion 13a projecting downward from the filtration case 14 is fitted to the water supply port 8 of the washing machine 1 shown in FIG. 2 via a packing (not shown), and is connected in a watertight and detachable manner. A water supply path for supplying water to a washing tub (not shown) inside the washing machine 1 is formed.
これに対し、濾過ケース14の前記流入口12は、前記キャップ14bの中央部に上下方向に延びる円筒状の筒状部12aにて形成され、該筒状部12aはキャップ14bの内外に突出するとともに、上部の外部側に大きく突出した構成としている。この外部に突出した筒状部12aの上端部は、図2に示す給水ホース10と嵌合により連結され、延いては水道の蛇口9に接続されることで水源からの給水経路を形成している。従って、濾過装置2は水源から洗濯機1に至る給水経路中に設けられ、且つ流入口12を上部位置に、流出口13を下部位置とする上下に指向した状態でセットされる。
On the other hand, the inlet 12 of the filtration case 14 is formed by a cylindrical cylindrical portion 12a extending in the vertical direction at the center of the cap 14b, and the cylindrical portion 12a protrudes into and out of the cap 14b. At the same time, it is configured to protrude greatly to the outside on the upper side. The upper end portion of the cylindrical portion 12a protruding to the outside is connected to the water supply hose 10 shown in FIG. 2 by fitting, and then connected to a tap faucet 9 to form a water supply path from a water source. Yes. Accordingly, the filtration device 2 is provided in a water supply path from the water source to the washing machine 1 and is set in a vertically oriented state with the inlet 12 as the upper position and the outlet 13 as the lower position.
次いで、上記濾過ケース14内に設けられた濾材15と、該濾材15を所定位置に保持するコアユニット23の構成について説明する。まずコアユニット23の構成につき述べると、全容としては上面を閉鎖し下面を開放した円筒状をなしていて、濾過ケース14の内周面との間には通水路としての所定の間隙を有して収容される。
Next, the configuration of the filter medium 15 provided in the filter case 14 and the core unit 23 that holds the filter medium 15 in a predetermined position will be described. First, the configuration of the core unit 23 will be described. As a whole, the core unit 23 has a cylindrical shape with the upper surface closed and the lower surface open, and has a predetermined gap as a water passage between the inner peripheral surface of the filtration case 14. Is contained.
更に具体的に述べると、コアユニット23は例えばポリプロピレン樹脂で一体成形され、円筒状のコア部材24と、その上面を閉鎖した円板状の保持板25とから構成されている。そのうち、保持板25は濾過ケース14内の上部に位置し、該保持板25の上面が流入口12と直交するように対向配置され、従って図1中に矢印で示す流入口12からの水の流入方向と直交する配置状態にある。
More specifically, the core unit 23 is integrally formed of, for example, polypropylene resin, and includes a cylindrical core member 24 and a disc-shaped holding plate 25 whose upper surface is closed. Among them, the holding plate 25 is located at the upper part in the filter case 14 and is disposed so as to face the inlet 12 so that the upper surface of the holding plate 25 is orthogonal to the inlet 12, and therefore water from the inlet 12 shown by an arrow in FIG. It is in an arrangement state orthogonal to the inflow direction.
上記保持板25は、本実施形態では特に図3に明示するように平坦状の上面の中心部から放射状に延びる複数(例えば4個)の突起部26を一体に設けている。この突起部26は、上記流入口12の開口面積に相当する中心部位を除いて放射状に形成され、垂直に起立した板状に突出形成されている。なお、この保持板25および放射状の突起部26は、詳細な作用説明は後述するが上記流入口12から流入した水を保持板25で受けて、水の流れを直角に曲げて外周方向に流すとともに、この際、放射状の突起部26により水を均等に分散して流す整流作用をなす。このため、該突起部26は板状に限らず、例えば断面山形状としてもよいし、或は連続した突起部の形状でなく棒状の突起群としてもよいなど、種々変形して実施可能である。
In the present embodiment, the holding plate 25 is integrally provided with a plurality of (for example, four) protrusions 26 extending radially from the center of the flat upper surface, as particularly shown in FIG. The protrusions 26 are formed in a radial shape except for a central portion corresponding to the opening area of the inflow port 12, and are formed so as to protrude vertically. The holding plate 25 and the radial protrusion 26 receive the water flowing in from the inflow port 12 by the holding plate 25 and bend the water flow at right angles to flow in the outer peripheral direction, although the detailed description of the operation will be described later. At the same time, the radial protrusions 26 provide a rectifying action for evenly distributing and flowing water. Therefore, the protrusion 26 is not limited to a plate shape, and may be implemented with various modifications, such as a cross-sectional mountain shape, or a bar-shaped protrusion group instead of a continuous protrusion shape. .
一方、円筒状のコア部材24は、周壁のほぼ全面にわたって例えば格子状の複数の透孔24aを形成していて、内外の通水性が良好な構成としている。ただし、各透孔24a形状は、上記保持板25とコア部材24との一体成形を容易にする形状としてもよく、従って円形状の透孔としても良いし、必ずしも同一形状とする必要もない。このコア部材24は、保持板25より若干径小の円筒状をなしていて、その外周面に濾材15を巻装保持している。
On the other hand, the cylindrical core member 24 is formed with, for example, a plurality of lattice-shaped through holes 24a over almost the entire surface of the peripheral wall, so that water permeability inside and outside is good. However, the shape of each through hole 24a may be a shape that facilitates integral molding of the holding plate 25 and the core member 24, and thus may be a circular through hole, and does not necessarily have to be the same shape. The core member 24 has a cylindrical shape slightly smaller in diameter than the holding plate 25, and the filter medium 15 is wound and held on the outer peripheral surface thereof.
ここで、濾材15につき詳述すると、濾材15の素材としては、古着や不要となった衣類生地など柔軟な布生地であれば利用可能で、例えば本実施形態では白色系の不織布をシート状に切り出したものを、図3に示すように円筒状に形成している。すなわち、シート状の両端部を縫い合わせて、前記コア部材24の直径寸法とほぼ等しい円筒形状の濾材15を得るようにしている。
Here, the filter medium 15 will be described in detail. As a material of the filter medium 15, any flexible cloth such as old clothes or unnecessary clothes can be used. For example, in this embodiment, a white nonwoven fabric is formed into a sheet. The cut out is formed in a cylindrical shape as shown in FIG. That is, both ends of the sheet shape are stitched together to obtain a cylindrical filter medium 15 substantially equal to the diameter of the core member 24.
従って、この濾材15を、その柔軟性や弾力性を利用してコア部材24の外周面に嵌め込むように巻装することで容易に脱落することなく保持される。この場合、コア部材24に巻装保持された状態では、図1に示すように濾材15の下端部がコア部材24の下端部より若干短い寸法に設定していて、つまり濾材15の内周面の全面がコア部材24の外周面に密着する形態としている。
Therefore, the filter medium 15 is held without being easily dropped by being wound so as to be fitted into the outer peripheral surface of the core member 24 using its flexibility and elasticity. In this case, in a state where the core member 24 is wound and held, the lower end portion of the filter medium 15 is set to be slightly shorter than the lower end portion of the core member 24 as shown in FIG. The entire surface is in close contact with the outer peripheral surface of the core member 24.
このように、濾材15を保持したコアユニット23は、濾過ケース14内の所定位置に収容される。すなわち、キャップ14bを取り外した状態のケース本体14a内にコアユニット23をコア部材24側から収容する。コア部材24は、前記したように環状の台座18とほぼ同一の径寸法位置に形成されている。このため、コア部材24の下端部が台座18の上端部に当接するとともに、本実施形態では、コア部材24に巻装した濾材15の下端部も前記台座18の上端部で受け止める構成とした。
Thus, the core unit 23 holding the filter medium 15 is accommodated in a predetermined position in the filter case 14. That is, the core unit 23 is accommodated from the core member 24 side in the case main body 14a with the cap 14b removed. As described above, the core member 24 is formed at substantially the same radial position as the annular pedestal 18. For this reason, while the lower end part of the core member 24 contact | abuts to the upper end part of the base 18, it was set as the structure which also receives the lower end part of the filter medium 15 wound around the core member 24 by the upper end part of the said base 18. FIG.
この場合、濾材15よりもコア部材24の下端部が下方に突出した状態にあるので、これら長さの異なる下端部に応じて当接し、受け止めることができるように台座18の上端面は異なる長さ寸法分に相当する段差を有する端面18a,18bを形成している。従って、内側の低い端面18aにはコア部材24の下端部が当接し、突出寸法Bにいう上端面に相当する外側の高い端面18bには濾材15の下端部が当接し、それぞれ支持される。このとき、コア部材24の下端部外周は段差部分で横方向への動きが規制され、所定位置に保持される。また、下端部を支持された濾材15は、重さなどにより下方へ滑り移動するのが阻止され、所定位置に保持される。そして、キャップ14bをケース本体14aに結合することで、濾材15を具備したコアユニット23は濾過ケース14内の所定位置にセットされる。
In this case, since the lower end portion of the core member 24 protrudes downward from the filter medium 15, the upper end surface of the pedestal 18 has a different length so that it can be brought into contact with and received by the lower end portions having different lengths. End surfaces 18a and 18b having steps corresponding to the length are formed. Therefore, the lower end portion of the core member 24 abuts on the inner lower end surface 18a, and the lower end portion of the filter medium 15 abuts on the outer high end surface 18b corresponding to the upper end surface in the protruding dimension B, and is supported. At this time, the outer periphery of the lower end portion of the core member 24 is held at a predetermined position by restricting the lateral movement at the step portion. Further, the filter medium 15 supported at the lower end is prevented from sliding downward due to weight or the like, and is held at a predetermined position. The core unit 23 including the filter medium 15 is set at a predetermined position in the filter case 14 by coupling the cap 14b to the case body 14a.
このように収容されたコアユニット23の外周面は、図1からも明らかなように濾過ケース14内の上壁面および側壁面と所定の間隙を有して配置され、該間隙は給水時における水の通路として図中に示す矢印方向に流れる(詳細は後述する)。
As is apparent from FIG. 1, the outer peripheral surface of the core unit 23 accommodated in this way is arranged with a predetermined gap from the upper wall surface and the side wall surface in the filtration case 14, and the gap is the water at the time of water supply. Flows in the direction of the arrow shown in the figure (details will be described later).
次に、前記抗菌剤21およびその収容ケース22の具体構成について説明する。まず、抗菌剤21については組成および機能などについて述べると、この抗菌剤21は、図示するように適宜の多角形状(多面体)に形成されたタブレット状をなし、水に浸すと抗菌成分を溶出するもので、所謂水に対する徐溶性を有するもので、抗菌性を有する金属元素と、リン酸系ガラスとからなるものである。具体的には、例えば本実施形態において所望の抗菌成分を溶出するに好適とする銀酸化物が約3重量パーセント、酸化亜鉛が約27重量パーセント、酸化コバルトが約1重量パーセント、およびリン酸カルシウムが約69重量パーセントから構成されている。
Next, the specific configuration of the antibacterial agent 21 and its housing case 22 will be described. First, the composition and function of the antibacterial agent 21 will be described. The antibacterial agent 21 has a tablet shape formed in an appropriate polygonal shape (polyhedron) as shown in the figure, and elutes antibacterial components when immersed in water. In other words, it has a solubilized solubility in water and is composed of a metal element having antibacterial properties and phosphate glass. Specifically, for example, about 3 weight percent silver oxide, about 27 weight percent zinc oxide, about 1 weight percent cobalt oxide, and about 1 weight percent calcium phosphate are suitable for eluting the desired antimicrobial component in this embodiment. It consists of 69 weight percent.
上記各成分の機能としては、銀酸化物は抗菌性を有する銀イオンを抗菌成分として水中に溶出し、後の作用説明で述べるように洗濯中の洗濯物に抗菌効果を付与する。この銀酸化物の含有量が0.1重量パーセント以下であると実質的な抗菌作用が得られなくなり、5重量パーセント以上であると光によって褐色に変色し易くなり、製造コストも高くなる。よって、銀酸化物の含有量は、0.1~5重量パーセントが好ましい。
As a function of each of the above components, silver oxide elutes silver ions having antibacterial properties in water as an antibacterial component and imparts an antibacterial effect to the laundry being washed as will be described later. If the content of the silver oxide is 0.1% by weight or less, a substantial antibacterial action cannot be obtained, and if it is 5% by weight or more, the color is easily changed to brown by light and the production cost is increased. Therefore, the silver oxide content is preferably 0.1 to 5 weight percent.
酸化亜鉛は、主として銀酸化物の褐色化を防止する機能を担うものである。なお、この酸化亜鉛から溶出される亜鉛イオンにも、銀イオンほどではないが抗菌作用が認められることから、抗菌成分としての機能も担う。ただし、酸化亜鉛も若干ではあるが変色することがあるため、その含有量は50重量パーセント以下とすることが好ましい。
Zinc oxide is mainly responsible for preventing browning of silver oxide. In addition, since the antibacterial action is recognized also to the zinc ion eluted from this zinc oxide, although not as much as a silver ion, it also functions as an antibacterial component. However, since zinc oxide may be slightly discolored, the content is preferably 50% by weight or less.
酸化コバルトは、抗菌剤21自体を青色に着色するための金属酸化物として添加されるもので、極めて少ない含有量でも抗菌剤21を鮮やかな青色に着色することができる。この着色により、詳細は後述するが抗菌剤21の有無や残量を目視により確認するのに有効である。
Cobalt oxide is added as a metal oxide for coloring the antibacterial agent 21 itself in blue, and the antibacterial agent 21 can be colored in vivid blue even with a very small content. Although this will be described in detail later, this coloring is effective for visually confirming the presence or absence and the remaining amount of the antibacterial agent 21.
そして、上記リン酸系ガラスは、溶解性ガラスとしてリン酸成分(P205)を主成分としているが、このリン酸成分(P205)は、ガラスの透明性を維持したり、銀イオンを洗濯水中に徐溶させる効果を有する。ただし、濃度が10重量パーセントを下回ると機械的強度を維持できなくなるおそれがあり、一方、80重量パーセントを超えても機械的強度の低下を招くおそれがある。そのため、リン酸成分(P205)の含有量は、抗菌剤21全体の10~80重量パーセントが好ましく、最適には30~70重量パーセントとするのがよい。しかも、このリン酸成分は水に溶解すると、洗濯水である水道水中のカルシウムやマグネシウムに対してキレート構造(Ca2P60182-、Mg2P60182-)を取るので、カルシウム分の水溶解性を高め、界面活性剤の効果を高めて洗浄性能の向上を図ることができる。
The phosphoric acid-based glass mainly contains a phosphoric acid component (P205) as a soluble glass, and this phosphoric acid component (P205) maintains the transparency of the glass or allows silver ions to be contained in washing water. Has the effect of slow dissolution. However, if the concentration is less than 10 percent by weight, the mechanical strength may not be maintained, while if it exceeds 80 percent by weight, the mechanical strength may be reduced. Therefore, the content of the phosphoric acid component (P205) is preferably 10 to 80 weight percent of the whole antibacterial agent 21, and optimally 30 to 70 weight percent. In addition, when this phosphoric acid component dissolves in water, it has a chelate structure (Ca2P6018 2− , Mg2P6018 2− ) with respect to calcium and magnesium in tap water which is washing water, so that the water solubility of calcium is increased and the interface is increased. The effect of the activator can be enhanced to improve the cleaning performance.
また、従来の方法では抗菌成分である銀イオンが、水道水中の陰イオン、特に塩素イオン、硫化物イオンなどと結合すると、溶解度積が小さい塩を生成して溶解度が減少し、抗菌成分である銀イオンが水中に放出されなくなる。このため、洗濯物の衣類などにコートされても有効とするほどの抗菌成分が溶出せず、抗菌効果が低下する傾向にあった。
In addition, when silver ions, which are antibacterial components, are combined with anions in tap water, in particular chloride ions, sulfide ions, etc. in the conventional method, a salt with a low solubility product is formed and the solubility is reduced, and the antibacterial component Silver ions are no longer released into the water. For this reason, even if it is coated on clothes of laundry, antibacterial components that are effective do not elute, and the antibacterial effect tends to decrease.
これに対し、本実施形態では陰イオンとしてリン酸成分を溶出するので、該リン酸成分により上記のような難溶解性の塩を生成することなく、溶出した銀イオンを有効な抗菌効果を有する状態に安定的に保つことができ、抗菌作用を効果的に持続させることができる。
On the other hand, in this embodiment, since the phosphate component is eluted as an anion, the eluted silver ion has an effective antibacterial effect without generating the above-mentioned hardly soluble salt by the phosphate component. The state can be stably maintained, and the antibacterial action can be effectively maintained.
次いで、上記抗菌剤21を収容する収容ケース22の具体構成につき、図1、図3および図4を参照して述べる。そのうち図4は収容ケース22を示す斜視図で、該収容ケース22は樹脂成形により全体構成を一体に成形している。この収容ケース22は、円筒状で有底容器状の容器部22aと、該容器部22aの上面開口を開閉可能とする平板状の蓋部22bとから構成される。具体的には、蓋部22bの周端部の一部が、容器部22aの上端部と連結した状態で一体に成形され、且つその連結部を薄肉部としたり、更には切り込みを入れるなどして柔軟性を持たせることで、蓋部22bを回動可能(図4の矢印方向)とするヒンジ部22cを形成しており、もって蓋部22bを容器部22aに対し開閉可能としている。
Next, a specific configuration of the housing case 22 that houses the antibacterial agent 21 will be described with reference to FIGS. 1, 3, and 4. 4 is a perspective view showing the housing case 22, and the housing case 22 is integrally molded by resin molding. The housing case 22 includes a cylindrical container portion 22a having a bottomed container shape and a flat lid portion 22b that can open and close the upper surface opening of the container portion 22a. Specifically, a part of the peripheral end portion of the lid portion 22b is integrally formed in a state where it is connected to the upper end portion of the container portion 22a, and the connecting portion is made into a thin-walled portion or further cut. By providing flexibility, a hinge portion 22c that allows the lid portion 22b to rotate (in the direction of the arrow in FIG. 4) is formed, so that the lid portion 22b can be opened and closed with respect to the container portion 22a.
そのうち容器部22aは、具体的には中空の容器状をなすように、中央部に円筒状の内筒部27を底部側から立設し、その上端部には内方(開口)側に水平に延びるフランジ部27aを形成している。そして、容器部22aの外周側壁には多数の通水孔28を形成している。この多数の通水孔28は、内部に収容した抗菌剤21の抗菌成分が容器外に流出可能とすることはもとより、内部の抗菌剤21の残量などの収容状態を外部から容易に目視できるように開口形状も含めて考慮されている。
Among them, the container portion 22a is provided with a cylindrical inner tube portion 27 standing from the bottom side at the center so as to form a hollow container, and horizontally at the upper (opening) side at the upper end portion. A flange portion 27a extending in the direction is formed. And many water flow holes 28 are formed in the outer peripheral side wall of the container part 22a. The large number of water passage holes 28 allow the antibacterial component of the antibacterial agent 21 accommodated therein to flow out of the container and allows the state of accommodation such as the remaining amount of the antibacterial agent 21 to be easily visually observed from the outside. Thus, the opening shape is also taken into consideration.
一方、蓋部22bの具体形状は、中央部に上記内筒部27の直径とほぼ同寸法の開口部29と、多数の通水孔30を形成している。また、ヒンジ部22c以外の外周端部の3箇所に弾性変形可能な係合爪部31を突設している。この係合爪部31は、蓋部22bを閉鎖状態に保持する係合手段を構成するもので、これら係合爪部31と対応する容器部22a側の外周上端部の3箇所に、該係合爪部31を弾性的に引っ掛ける被係合部32を形成している。この場合、係合爪部31を径方向に弾性変形することで、係合および離脱可能とする係合手段を構成している。
On the other hand, the specific shape of the lid portion 22b is formed with an opening 29 having approximately the same size as the diameter of the inner cylinder portion 27 and a large number of water passage holes 30 at the center. In addition, engaging claw portions 31 that can be elastically deformed are projected at three locations on the outer peripheral end other than the hinge portion 22c. This engagement claw portion 31 constitutes an engagement means for holding the lid portion 22b in a closed state. The engagement claw portion 31 has three engagement claw portions 31 corresponding to the engagement claw portion 31 at three locations on the outer peripheral upper end portion on the container portion 22a side. An engaged portion 32 that elastically hooks the pawl portion 31 is formed. In this case, the engaging claw part 31 is elastically deformed in the radial direction to constitute an engaging means that can be engaged and disengaged.
従って、図1に示すように抗菌剤21が収納され容器部22aに蓋部22bが閉鎖状態にある収容ケース22は、中央に穴部を備えたドーナツ形状をなしている。そして、濾過ケース14内底部の第1の凹所19に収容された収容ケース22は、その内筒部27が流出口13の筒状部13aに嵌合した状態で、且つ該筒状部13aの上端部にフランジ部27aが衝止されることで所定位置に収容保持される。もって、濾過ケース14内に水に対する徐溶性を有する抗菌剤21を収容して抗菌成分を溶出可能とした、所謂抗菌機能を備えた濾過装置2が構成される。
Therefore, as shown in FIG. 1, the storage case 22 in which the antibacterial agent 21 is stored and the lid 22b is closed in the container 22a has a donut shape with a hole in the center. The housing case 22 housed in the first recess 19 in the inner bottom portion of the filtration case 14 is in a state where the inner tubular portion 27 is fitted to the tubular portion 13a of the outlet 13 and the tubular portion 13a. The flange portion 27a is latched to the upper end of each of the two, and is held and held in a predetermined position. Therefore, the filtration device 2 having a so-called antibacterial function is configured in which the antibacterial agent 21 having a slow solubility in water is accommodated in the filter case 14 and the antibacterial component can be eluted.
次に、上記構成の洗濯機1に適用した抗菌機能を備えた濾過装置2の作用について述べる。外部水源からの水道水は、蛇口9を開放することで給水ホース10、濾過装置2、洗濯機1の給水口8を経て図示しない洗濯槽に供給される。そして、所定水量の給水後は、蛇口9を閉鎖することで給水動作は停止する。その後は、操作パネル7を操作して所望の洗濯運転コース等を設定して運転をスタートすることで、一般周知の洗濯運転が実行される(詳細な説明は省略する)。
Next, the operation of the filtration device 2 having an antibacterial function applied to the washing machine 1 having the above-described configuration will be described. Tap water from an external water source is supplied to a washing tub (not shown) through the water supply hose 10, the filtering device 2, and the water supply port 8 of the washing machine 1 by opening the faucet 9. And after water supply of predetermined amount of water, water supply operation | movement is stopped by closing faucet 9. Thereafter, by operating the operation panel 7 to set a desired washing operation course and the like and starting the operation, a generally known washing operation is executed (detailed description is omitted).
そこで、以下に上記濾過装置2を経た給水動作により機能する抗菌作用および濾過作用について詳細に述べる。まず、濾過装置2が本来有する濾過機能について説明する。濾過装置2は、上記したように洗濯機1への給水経路中に設けられており(図2参照)、蛇口9の開放に伴い水道水は濾過装置2に達する。この濾過装置2に達した水は、図1に示すように濾過ケース14の上部の流入口12から該濾過ケース14内に流入し、図中に示す矢印方向に流下する。
Therefore, the antibacterial action and the filtering action that function by the water supply operation through the filtering device 2 will be described in detail below. First, the filtering function that the filtering device 2 originally has will be described. As described above, the filtering device 2 is provided in the water supply path to the washing machine 1 (see FIG. 2), and the tap water reaches the filtering device 2 as the faucet 9 is opened. As shown in FIG. 1, the water that has reached the filtration device 2 flows into the filtration case 14 from the inlet 12 at the top of the filtration case 14, and flows down in the direction of the arrow shown in the figure.
すなわち、水はコアユニット23の保持板25に衝突して流れが直角方向に方向変換される。この場合、水は保持板25の上面に設けられた放射状に延びる突起部26に案内されて均等に分散する整流作用を受けることで、無用な渦流などの乱流を生じることなく外周方向への水の流れや水量を均等化しつつ、効率よく濾過ケース14内の外周側に流下する。よって、水は濾材15の周囲全面においてほぼ同じ条件のもとで通過可能となり、その際に鉄錆などの不純物を効果的に捕獲し濾過する。
That is, the water collides with the holding plate 25 of the core unit 23 and the flow is redirected in a right angle direction. In this case, the water is guided by the radially extending projections 26 provided on the upper surface of the holding plate 25 and is subjected to a rectifying action that is evenly distributed, so that water does not generate turbulent flow such as unnecessary vortex flow in the outer circumferential direction. It efficiently flows down to the outer peripheral side in the filtration case 14 while equalizing the flow and amount of water. Therefore, water can pass under almost the same conditions around the entire surface of the filter medium 15, and at that time, impurities such as iron rust are effectively captured and filtered.
そして、濾材15を通過し浄化した水はコア部材24の透孔24aを経て内方に流入し、流出口13の上端開口を越える水位に達した後、該流出口13から外部に排出可能となり、つまり洗濯機1の給水口8から洗濯槽に供給される。なお、水道水による供給側の水量や水圧が勝るため給水動作の継続実行に伴い、濾過装置2を含む給水経路は水で満たされた状態となり、濾材15を通過した水は流出口13から円滑に連続して流出される。
The purified water that has passed through the filter medium 15 flows inward through the through holes 24a of the core member 24, reaches the water level that exceeds the upper end opening of the outlet 13, and can be discharged to the outside from the outlet 13. That is, it is supplied to the washing tub from the water supply port 8 of the washing machine 1. Since the amount of water and water pressure on the supply side with tap water are superior, the water supply path including the filtering device 2 is filled with water as the water supply operation is continued, and the water passing through the filter medium 15 is smoothly discharged from the outlet 13. Is continuously discharged.
この結果、給水の全てが濾材15を通して濾過されるので、水道水中に混入した鉄錆(赤錆)や微細な不純物などを有効に除去できる。つまり、濾過装置2による本来の濾過機能を発揮して不純物を濾過した清浄な水を洗濯機1に供給することができる。そして、洗濯機1(洗濯槽)への給水が完了したら蛇口9を回動操作して閉鎖することで、水の供給を停止し給水動作を終了する。
As a result, since all of the water supply is filtered through the filter medium 15, iron rust (red rust) and fine impurities mixed in tap water can be effectively removed. In other words, it is possible to supply the washing machine 1 with clean water from which impurities are filtered by exhibiting the original filtering function of the filtering device 2. When the water supply to the washing machine 1 (washing tub) is completed, the faucet 9 is turned and closed to stop the supply of water and the water supply operation is terminated.
ただし、蛇口9の閉鎖による給水停止直後では、濾過装置2を有する給水経路中には水が残っているため、この残水は濾過ケース14から徐々に流出し洗濯槽内へ流入することになる。この流出は、濾過ケース14内の水位が低下して流出口13たる筒状部13aの上端開口面の位置に達するまで流出し、それ以後、水の流出は停止する。つまり、筒状部13aの上端開口面は、ケース本体14aの底部から上方に突出(図1中に示す突出寸法Aに相当)した構成にある。このため、筒状部13aの上端開口面と濾過ケース14内の残水の水位Sは図1中二点鎖線で示すように同一高さにあることから、残水量は底部から流出口13の上端開口面との間の空間に相当する量が貯留され、本実施形態では第1の凹所19および第2の凹所20を合わせたものに相当する。
However, immediately after the stop of the water supply due to the closure of the faucet 9, water remains in the water supply path having the filtration device 2, so this residual water gradually flows out from the filter case 14 and flows into the washing tub. . This outflow flows out until the water level in the filtration case 14 decreases and reaches the position of the upper end opening surface of the cylindrical portion 13a as the outflow port 13. Thereafter, the outflow of water stops. That is, the upper end opening surface of the cylindrical portion 13a is configured to protrude upward (corresponding to the protruding dimension A shown in FIG. 1) from the bottom of the case body 14a. For this reason, since the water level S of the upper end opening surface of the cylindrical part 13a and the residual water in the filtration case 14 are at the same height as shown by a two-dot chain line in FIG. 1, the residual water amount is from the bottom to the outlet 13. An amount corresponding to the space between the upper end opening surface is stored, and in this embodiment, corresponds to a combination of the first recess 19 and the second recess 20.
これに対し、抗菌剤21による抗菌機能について説明すると、図1に示されるように抗菌剤21は、収容ケース22内にあって濾過ケース14の底部である流出口13周りの第1の凹所19内に収容されている。従って、上記した給水動作が初回である場合には、未だ第1の凹所19などには残水による貯留は認められないことから、給水動作により濾材15を通過した水が第1の凹所19内に流入することで初めて抗菌剤21と接触する。この第1の凹所19内の水は、下部に流出口がないためやや滞留する傾向にあって緩慢な流れ(溢流)となるが、続いて濾過ケース14内に流入してくる水とともに流出口13から流出する。このため、第1の凹所19内の水は新しい水と置換されつつ流出し、洗濯機1(洗濯槽)への給水動作が実行される。
On the other hand, the antibacterial function of the antibacterial agent 21 will be described. As shown in FIG. 1, the antibacterial agent 21 is in the housing case 22 and is a first recess around the outlet 13 that is the bottom of the filtration case 14. 19. Therefore, when the above-mentioned water supply operation is the first time, since the remaining water is not yet stored in the first recess 19 or the like, the water that has passed through the filter medium 15 by the water supply operation has not been confirmed. It contacts the antibacterial agent 21 for the first time by flowing into 19. The water in the first recess 19 tends to stay slightly because there is no outlet at the lower part, and becomes a slow flow (overflow). Subsequently, along with the water flowing into the filtration case 14 It flows out from the outlet 13. For this reason, the water in the first recess 19 flows out while being replaced with new water, and the water supply operation to the washing machine 1 (washing tub) is executed.
ところで、徐溶性の抗菌剤21は給水動作中、水に浸された状態にあることから抗菌成分が溶出することが可能である。しかしながら、水との接触時間が短時間である給水動作において、所望の抗菌効果を得られるようにしたり、或は給水動作(時間)が洗濯物量に応じて変更されても安定した抗菌効果が得られるように溶解度を調整することは難しく、例えばそのために溶解性を高めた抗菌剤は、早期に溶解して消耗し易く多量の抗菌剤を使用することになるなどの難点を有する。
By the way, since the slowly soluble antibacterial agent 21 is immersed in water during the water supply operation, the antibacterial component can be eluted. However, a stable antibacterial effect can be obtained even when a desired antibacterial effect is obtained in a water supply operation in which the contact time with water is short, or even if the water supply operation (time) is changed according to the amount of laundry. Therefore, it is difficult to adjust the solubility. For example, an antibacterial agent having improved solubility for this purpose has a drawback that it is likely to be dissolved and consumed quickly, and a large amount of the antibacterial agent is used.
そこで、本実施形態における抗菌剤21は、初回の給水動作以後に生じる残水を利用して徐々に抗菌成分を溶出するようにして、次回の洗濯の給水動作時に適正な濃度に達した抗菌成分を給水とともに洗濯槽内に供給できるようにしている。例えば、リン酸系ガラスの主成分であるリン酸成分の配分を調整して、抗菌成分たる銀イオンの溶出度合を調整することで、好適とする若干難溶解性の抗菌剤21を得ることができる。なお、抗菌成分を溶出する水量は、上記したように第1の凹所19および第2の凹所20を合わせた一定の残水量に設定される。
Therefore, the antibacterial agent 21 in the present embodiment gradually dissolves the antibacterial component using the residual water generated after the first water supply operation, so that the antibacterial component reaches an appropriate concentration during the next water supply operation of the laundry. Can be supplied into the washing tub together with the water supply. For example, by adjusting the distribution of the phosphoric acid component, which is the main component of the phosphate glass, and adjusting the elution degree of silver ions as the antibacterial component, a slightly slightly soluble antibacterial agent 21 can be obtained. it can. Note that the amount of water that elutes the antibacterial component is set to a constant residual water amount that combines the first recess 19 and the second recess 20 as described above.
この実施形態では、毎日洗濯を行なうことを想定して、翌日の洗濯を行なうときに所望の抗菌効果を得られる徐溶性を有する組成成分としている。これにより、比較的長時間を経て所望の抗菌成分を溶出するようにしているので抗菌剤21が早期に溶解して消耗することを抑制できる。例えば、実使用において1回の洗濯作業ではすすぎ洗いも含め2~4回程度の給水動作が実行されるが、その際の抗菌剤21の早期溶解を阻止できるとともに、残水との接触時間に誤差(バラツキ)があっても、やはり抗菌剤21の早期溶解を抑制できる。しかも、残水量はほぼ一定であるので溶出する抗菌成分が飽和状態になるのに伴い、それ以上の溶解を阻止できるなど、長期間使用可能とすることができて抗菌剤21の補給作業も軽減できるとともに、洗濯物に対し安定した所望の抗菌効果を得ることができる。
In this embodiment, assuming that washing is performed every day, the composition component has a slow solubility so that a desired antibacterial effect can be obtained when washing the next day. Thereby, since a desired antibacterial component is eluted after a relatively long time, the antibacterial agent 21 can be prevented from being dissolved and consumed at an early stage. For example, in actual use, the water supply operation is performed about 2 to 4 times including the rinsing in one washing operation, but the early dissolution of the antibacterial agent 21 can be prevented and the contact time with the remaining water can be reduced. Even if there is an error (variation), the early dissolution of the antibacterial agent 21 can still be suppressed. In addition, since the amount of residual water is almost constant, as the eluted antibacterial component becomes saturated, it can be used for a long period of time, such as preventing further dissolution, and the replenishment work of the antibacterial agent 21 is also reduced. It is possible to obtain a desired antibacterial effect which is stable for laundry.
なお、前記した濾過ケース14内の残水水位Sについて補足すると、これは筒状部13aの上端開口面とほぼ同一高さとする水位にある。この残水水位Sに対し、第2の凹所20側の台座18は、突出寸法Bで示すように突出高さが低い。また、該台座18の上端部にはコア部材24および濾材15の下端部を支持しているが、その支持構成は格別な水密構成を有せず且つ濾材15は水が浸透する素材なので、残水水位Sは台座18を越えて第1の凹所19および第2の凹所20内とも同一水位となるとともに、濾材15の下端部は残水中に浸漬した状態となる(図1参照)。
In addition, if it supplements about the above-mentioned residual water level S in the filtration case 14, this exists in the water level made into the substantially same height as the upper end opening surface of the cylindrical part 13a. With respect to the residual water level S, the pedestal 18 on the second recess 20 side has a low protruding height as indicated by a protruding dimension B. The upper end of the pedestal 18 supports the core member 24 and the lower end of the filter medium 15, but the support structure does not have a special watertight structure and the filter medium 15 is a material that allows water to penetrate. The water level S exceeds the pedestal 18 and becomes the same water level in the first recess 19 and the second recess 20, and the lower end of the filter medium 15 is immersed in the remaining water (see FIG. 1).
この結果、本実施形態の洗濯機1による初回の洗濯作業においては、給水動作中の水と初めて接触する抗菌剤21による洗濯物への抗菌効果は十分ではないが、翌日の洗濯作業では濾過ケース14内の残水に浸された抗菌剤21は、残水水位Sによる所定水量のもとに、所望の抗菌成分を溶出した状態から開始される。このため、最初の洗い運転の給水動作において洗濯槽への給水とともに抗菌剤21が供給され、洗い運転を経て洗濯物への抗菌成分が十分に付与される。なお、この洗濯水が排水され、新たに給水およびすすぎ洗いが行なわれても、洗濯物に付与された抗菌効果は十分に維持できる。
As a result, in the first washing operation by the washing machine 1 of the present embodiment, the antibacterial effect on the laundry by the antibacterial agent 21 that contacts the water during the water supply operation for the first time is not sufficient. The antibacterial agent 21 soaked in the remaining water in 14 starts from a state in which a desired antibacterial component is eluted under a predetermined amount of water based on the residual water level S. For this reason, the antibacterial agent 21 is supplied with the water supply to the washing tub in the water supply operation of the first washing operation, and the antibacterial component is sufficiently imparted to the laundry through the washing operation. In addition, even if this washing water is drained and water supply and rinsing are newly performed, the antibacterial effect imparted to the laundry can be sufficiently maintained.
また、上記したように濾過ケース14内の残水水位Sは、濾材15の下端部を浸漬状態に保持するので、水中に溶出した抗菌成分は濾材15の下端部から上部へ徐々に浸透する。従って、次回の洗濯作業が行なわれるまで貯留された抗菌成分を含んだ残水は、濾材15への浸透により濾材15自体の抗菌作用が期待できる。
Further, as described above, the residual water level S in the filter case 14 keeps the lower end portion of the filter medium 15 in an immersed state, so that the antibacterial components eluted in the water gradually permeate from the lower end portion of the filter medium 15 to the upper portion. Therefore, the residual water containing the antibacterial component stored until the next washing operation is performed can be expected to have an antibacterial action of the filter medium 15 itself due to permeation into the filter medium 15.
斯くして、水源から供給された洗浄水たる洗濯水は、濾過装置2の本来の濾過機能により鉄錆などの不純物を濾過して除去した清浄な水とするとともに、濾過装置2内に備えた抗菌機能により洗濯物への抗菌効果を付与する水として、洗濯機1に供給でき清潔で安全な洗濯物の洗い上がり効果が期待できる。
Thus, the washing water, which is the washing water supplied from the water source, is a clean water in which impurities such as iron rust are filtered and removed by the original filtration function of the filtration device 2 and is provided in the filtration device 2. As water that imparts an antibacterial effect to the laundry due to the antibacterial function, it can be supplied to the washing machine 1 and a clean and safe laundry washing effect can be expected.
このように濾過装置2を使用するうちに、鉄錆などの不純物を捕獲した濾材15、および消耗品である抗菌剤21の残量については、その状況を保守点検により確認する必要がある。例えば本実施形態では、少なくともケース本体14aを透明樹脂製としているので、濾材15に対する鉄錆(赤錆)による目詰り状態については、赤色化した汚れ具合に基づき外部から目視にて判別でき、濾材15の適切な交換時期や洗浄時期を容易に知ることができる。従って、濾材15は白色系の素材を採用することが容易に判別できる点で有効である。
As described above, it is necessary to check the status of the filter medium 15 that captures impurities such as iron rust and the remaining amount of the antibacterial agent 21 that is a consumable item through maintenance and inspection while the filter device 2 is used. For example, in this embodiment, since at least the case main body 14a is made of a transparent resin, the clogged state due to iron rust (red rust) on the filter medium 15 can be visually discriminated from the outside based on the redness of the dirt, and the filter medium 15 It is possible to easily know the appropriate replacement time and cleaning time. Therefore, the filter medium 15 is effective in that it can be easily determined that a white material is adopted.
一方、抗菌剤21の残量を確認したい場合、抗菌剤21も透明樹脂製のケース本体14aの底部たる第1の凹所19内に収容している。抗菌剤21を収納する収容ケース22は、その外周側に多数の通水孔28を設けていることから、該通水孔28から内部の抗菌剤21の残量を目視でき、よって透明な濾過ケース14の外部からも目視にて確認できる。この場合、抗菌剤21は酸化コバルトにより鮮やかに青色に着色しているので、その残量を一層容易に且つ正確に視認できる。なお、収容ケース22もケース本体14aと同様に透明樹脂製とすれば、一層容易に視認可能である。
On the other hand, when it is desired to check the remaining amount of the antibacterial agent 21, the antibacterial agent 21 is also housed in the first recess 19 which is the bottom of the transparent resin case body 14a. Since the storage case 22 for storing the antibacterial agent 21 is provided with a large number of water passage holes 28 on the outer peripheral side thereof, the remaining amount of the antibacterial agent 21 inside can be visually observed from the water passage hole 28, and thus transparent filtration It can also be confirmed visually from the outside of the case 14. In this case, since the antibacterial agent 21 is vividly colored blue with cobalt oxide, the remaining amount can be visually recognized more easily and accurately. Note that the housing case 22 can be visually recognized more easily if it is made of a transparent resin in the same manner as the case body 14a.
そして、点検結果に基づき濾材15の交換や抗菌剤21の補給などを行なう場合には、例えば濾過装置2を蛇口9につながる給水ホース10などの給水経路から分離する。この濾過装置2は、図3に示す部品単位に分解できる。すなわち、濾過ケース14はケース本体14aとキャップ14bとのねじ結合(雌雄のねじ部16a,16b)を解くだけで簡単に分離でき、その内部に収容されていたコアユニット23を取り出すことができる。当然、これに装着されていた濾材15も取り出すことができ、且つ分離することができる。従って、濾材15を新規なものと交換するか、或は濾材15を洗浄して目詰り状態を解消して再利用する場合は、この分解した段階で対応できる。
When the filter medium 15 is replaced or the antibacterial agent 21 is replenished based on the inspection result, for example, the filter device 2 is separated from the water supply path such as the water supply hose 10 connected to the faucet 9. The filtration device 2 can be disassembled into parts shown in FIG. That is, the filtration case 14 can be easily separated by simply unscrewing the screw connection (male and male screw portions 16a and 16b) between the case main body 14a and the cap 14b, and the core unit 23 accommodated therein can be taken out. Of course, the filter medium 15 attached to this can also be taken out and separated. Therefore, when the filter medium 15 is replaced with a new one, or when the filter medium 15 is washed to eliminate clogging and reused, it can be dealt with at this disassembled stage.
また、抗菌剤21を補給する場合は、上記コアユニット23を取り出した後、その下方に収容配置された収容ケース22を取り出す。収容ケース22は、図4に示すように容器部22aに対しヒンジ部22cを介して蓋部22bが開閉回動可能な構成であるため、閉鎖状態を保持するための係合爪部31と被係合部32との弾性係合は、係合爪部31を弾性変形させることで容易に離脱でき、蓋部22bを開放することができる。よって、新たな抗菌剤を補給して、再び蓋部22bを閉鎖状態に係合保持した収容ケース22をケース本体14a内底部の第1の凹所19に収容すればよい。この場合、ドーナツ形状の収容ケース22は、流出口13を形成する筒状部13aを位置決めガイドとして、これに挿入することで所定位置に収容配置できる。
Further, when replenishing the antibacterial agent 21, after taking out the core unit 23, the housing case 22 housed and arranged below it is taken out. As shown in FIG. 4, the housing case 22 is configured such that the lid portion 22b can be opened and closed with respect to the container portion 22a via a hinge portion 22c. The elastic engagement with the engaging portion 32 can be easily detached by elastically deforming the engaging claw portion 31, and the lid portion 22b can be opened. Therefore, a new antibacterial agent is replenished, and the accommodation case 22 in which the lid portion 22b is engaged and held again is accommodated in the first recess 19 in the inner bottom portion of the case body 14a. In this case, the donut-shaped accommodation case 22 can be accommodated and arranged at a predetermined position by inserting the cylindrical portion 13a forming the outlet 13 as a positioning guide.
なお、上記分解後の組立作業は、その逆手順で行なえばよく、すなわちケース本体14a底部の第1の凹所19に抗菌剤21を収納した収容ケース22を収容し、その上方を覆うように濾材15を装着したコアユニット23を収容する。この場合、コア部材24および濾材15の下端部を台座18に載置支持させるだけでよい。この状態のケース本体14aに対し、キャップ14bをパッキン17を介してねじ結合(雌雄のねじ部16a,16b)することで濾過ケース14が構成されるとともに、濾過装置2として組立が完了し、これを給水ホース10などの給水経路中にセットすればよい。
The assembly work after the disassembly may be performed in the reverse order, that is, the housing case 22 housing the antibacterial agent 21 is housed in the first recess 19 at the bottom of the case body 14a and the upper part thereof is covered. The core unit 23 equipped with the filter medium 15 is accommodated. In this case, it is only necessary to place and support the lower end portions of the core member 24 and the filter medium 15 on the pedestal 18. A filter case 14 is constructed by screwing the cap 14b to the case body 14a in this state via the packing 17 (male and female screw portions 16a and 16b), and the assembly as the filter device 2 is completed. May be set in the water supply path such as the water supply hose 10.
以上説明したように、二槽式の洗濯機1の濾過装置2に適用した実施形態によれば、次のような効果が期待できる。
外部水源から洗濯機1への給水経路中に濾過装置2を設け、該濾過装置2を構成する濾過ケース14の上下部に有する流入口12と流出口13との間の通水路を仕切るように、濾材15を設けたことにより、水中の鉄錆(赤錆)などの不純物を濾過して浄化した水を洗濯槽に供給し、洗濯できるようにした。よって、洗濯物などに鉄錆により変色するなどの弊害をなくすことができる。また、濾材15を収容する濾過ケース14を透視できるように透明な樹脂製としているので、外部から濾材15の目詰まり状態を目視でき、例えば鉄錆により赤色化する汚れ具合から容易に判別できる。これにより、濾材15を洗浄したり或は交換する時期を逸することがないなど、使い勝手に優れ一般家庭でも手軽に保守点検ができる。 As described above, according to the embodiment applied to thefiltration device 2 of the two-tank washing machine 1, the following effects can be expected.
Afiltration device 2 is provided in the water supply path from the external water source to the washing machine 1, and a water passage between the inlet 12 and the outlet 13 provided at the upper and lower portions of the filtration case 14 constituting the filtration device 2 is partitioned. By providing the filter medium 15, water purified by filtering impurities such as iron rust (red rust) in water is supplied to the washing tub so that it can be washed. Therefore, it is possible to eliminate the harmful effects such as discoloration of laundry due to iron rust. In addition, since the filter case 14 containing the filter medium 15 is made of a transparent resin so that the filter case 14 can be seen through, the clogged state of the filter medium 15 can be visually observed from the outside, and can be easily discriminated from, for example, the degree of dirt that turns red by iron rust. As a result, it is easy to use and maintenance can be performed easily even in ordinary households.
外部水源から洗濯機1への給水経路中に濾過装置2を設け、該濾過装置2を構成する濾過ケース14の上下部に有する流入口12と流出口13との間の通水路を仕切るように、濾材15を設けたことにより、水中の鉄錆(赤錆)などの不純物を濾過して浄化した水を洗濯槽に供給し、洗濯できるようにした。よって、洗濯物などに鉄錆により変色するなどの弊害をなくすことができる。また、濾材15を収容する濾過ケース14を透視できるように透明な樹脂製としているので、外部から濾材15の目詰まり状態を目視でき、例えば鉄錆により赤色化する汚れ具合から容易に判別できる。これにより、濾材15を洗浄したり或は交換する時期を逸することがないなど、使い勝手に優れ一般家庭でも手軽に保守点検ができる。 As described above, according to the embodiment applied to the
A
なお、本実施形態では濾材15を円筒状に形成してコア部材24に対して脱着可能に嵌合装着する構成としたが、これに限らず、例えばシート状の不織布をコア部材24に巻き付けて、この上から適宜の紐部材で束縛したり、或は弾性バンドを巻回して保持するようにしてもよいなど、簡単な脱着作業にて対応できる濾材15の取付手段は種々展開して実施可能である。
In the present embodiment, the filter medium 15 is formed in a cylindrical shape and is detachably fitted to the core member 24. However, the present invention is not limited to this. For example, a sheet-like nonwoven fabric is wound around the core member 24. The attachment means of the filter medium 15 that can be handled by a simple desorption operation, such as binding with an appropriate string member from above, or winding and holding an elastic band, can be implemented in various ways. It is.
また、濾材15を被着したコアユニット23を収容する際、そのコア部材24と濾材15の下端部を台座18で支持する構成としたが、これは特に台座18の形状にこだわるものではなく、ケース本体14aの底部側で所定高さ位置に支持される構成であればよい。
Further, when the core unit 23 to which the filter medium 15 is attached is accommodated, the core member 24 and the lower end portion of the filter medium 15 are supported by the pedestal 18, but this is not particularly concerned with the shape of the pedestal 18, What is necessary is just the structure supported by the predetermined height position by the bottom part side of the case main body 14a.
上記説明は濾過装置2として不純物除去による浄化した洗濯水を供給できる本来の濾過機能の効果について述べたが、更に本実施形態では該濾過装置2を利用して洗濯物に衛生的な抗菌効果を付与できる抗菌機能を設けたことを特徴としている。すなわち、この実施形態では水に対する徐溶性を有する抗菌剤21を、濾過ケース14の底部に収容配置する構成とした。よって、鉄錆などの不純物が除去されて清浄で、加えて抗菌成分を溶出した洗濯水を供給でき、洗濯物に所望の抗菌効果を付与できるなど清潔で衛生的な洗い上がり効果が期待できる。
Although the above description has described the effect of the original filtering function that can supply the washing water purified by removing impurities as the filtering device 2, this embodiment further uses the filtering device 2 to provide a hygienic antibacterial effect on the laundry. It is characterized by providing an antibacterial function that can be imparted. That is, in this embodiment, the antibacterial agent 21 having a slow solubility in water is configured to be accommodated in the bottom of the filtration case 14. Accordingly, it is possible to supply clean water with impurities such as iron rust removed, and also to supply wash water eluting antibacterial components, and to provide a desired antibacterial effect on the laundry.
しかも、上記した鉄錆などの濾過機能や、洗濯物へ抗菌効果を付与する抗菌機能は、これら機能を具備しない既存の各種洗濯機に対して、洗濯機外の給水経路中に濾過装置2を設けることで容易に機能させることができ、メンテナンスやコスト的にも有利に提供できる。
In addition, the filtration function such as iron rust and the antibacterial function that imparts an antibacterial effect to the laundry, the filtering device 2 is provided in the water supply path outside the washing machine for various existing washing machines that do not have these functions. By providing, it can be easily functioned, and can be advantageously provided in terms of maintenance and cost.
更に具体的には、抗菌剤21は収容ケース22内に収納され、該収容ケース22を利用して濾過装置2内から容易に脱着可能に配置されている。この場合、中央に穴部を有するドーナツ形状の収容ケース22を、流出口13を形成する筒状部13aをガイドとして挿脱する構成としたので、所定位置に容易に配置できるなど位置決めを含む脱着作業および抗菌剤21の取扱いなどが簡単作業にてできる。
More specifically, the antibacterial agent 21 is stored in a storage case 22 and is disposed so as to be easily removable from the filtration device 2 using the storage case 22. In this case, the doughnut-shaped housing case 22 having a hole in the center is configured to be inserted and removed using the cylindrical portion 13a forming the outlet 13 as a guide, so that it can be easily placed at a predetermined position and is attached and detached. Work and handling of the antibacterial agent 21 can be performed with simple work.
また、収容ケース22は多数の通水孔28,30を有し、溶出した抗菌成分の流出を容易にするだけでなく、特にそのうちの容器部22aの外周側に設けた通水孔28は、内部の抗菌剤21を外部から目視できるように考慮されて多数形成されている。これにより、透明部材によるケース本体14aの外部からも透視可能となる。従って、消耗品である抗菌剤21の残量等の状況を目視にて確認するのに有効で、その補給時期を逸することなく対応でき、有効な抗菌効果を常に発揮させることができる。しかも、本実施形態では抗菌剤21を酸化コバルト成分により鮮やかな青色に着色したので、外部から一層容易に視認できる利点を有する。
In addition, the housing case 22 has a large number of water holes 28 and 30 to facilitate the outflow of the eluted antibacterial component, and in particular, the water holes 28 provided on the outer peripheral side of the container portion 22a are: A large number of antibacterial agents 21 are formed in consideration so that they can be seen from the outside. Thereby, it is possible to see through from the outside of the case body 14a by the transparent member. Therefore, it is effective for visually confirming the situation such as the remaining amount of the antibacterial agent 21 that is a consumable item, can be handled without losing the replenishment time, and can always exhibit an effective antibacterial effect. In addition, in the present embodiment, the antibacterial agent 21 is colored bright blue by the cobalt oxide component, and thus has an advantage that it can be visually recognized from the outside more easily.
なお、上記収容ケース22は、樹脂製で容器部22aと蓋部22bとを一体成形として、蓋部22bをヒンジ部22cに介して開閉回動する構成とし、蓋部22bが離散しない点で取り扱いが容易であるが、これに限らず、別体に形成した蓋部をねじ結合としたり、弾性的に嵌合する着脱タイプの構成としてもよいなど、種々実施可能である。
The housing case 22 is made of resin, the container portion 22a and the lid portion 22b are integrally formed, and the lid portion 22b is opened and closed via the hinge portion 22c, and is handled in that the lid portion 22b is not dispersed. However, the present invention is not limited to this, and various implementations are possible, such as a lid part formed separately as a screw connection or a detachable type structure that fits elastically.
また、本実施形態では流出口13周りの第1の凹所19に収容した抗菌剤21は、筒状部13aの上端開口面より下位に収容配置される。つまり抗菌剤21を、濾過ケース14内の水が外部に流出する開口面より低位置に収容されるので、給水動作後には流出口13の上端開口面と同等の水位(図1中に残水水位Sで示す)とする残水の中に抗菌剤21が浸されることになる。従って、徐溶性の抗菌剤21の溶解度を適宜設定することで、残水中に所望の抗菌成分を溶出可能とし洗濯物に所望の抗菌効果を付与することができる。
Further, in this embodiment, the antibacterial agent 21 accommodated in the first recess 19 around the outlet 13 is accommodated and disposed below the upper end opening surface of the cylindrical portion 13a. That is, since the antibacterial agent 21 is accommodated at a position lower than the opening surface through which water in the filtration case 14 flows out, the water level equivalent to the upper end opening surface of the outlet 13 after the water supply operation (residual water in FIG. 1). The antibacterial agent 21 is immersed in the remaining water (indicated by the water level S). Therefore, by setting the solubility of the slowly-dissolving antibacterial agent 21 as appropriate, it is possible to elute a desired antibacterial component in the residual water and to impart a desired antibacterial effect to the laundry.
本実施形態では、翌日の洗濯作業まで残水中に抗菌剤21を浸漬する条件のもとで、抗菌成分を溶出し所望の抗菌効果を得るように設定している。すなわち、水と接触する度に所定の抗菌成分を溶出するのに対し、若干難溶解性の抗菌剤21とすることで、長時間かけて所望の抗菌成分を溶出するようにしたので、安定した所望の抗菌効果を得るのに有効であるとともに、該抗菌剤21を長期間使用可能となる利点を有する。
In the present embodiment, the antibacterial component is eluted and the desired antibacterial effect is obtained under the condition that the antibacterial agent 21 is immersed in the remaining water until the next day's washing operation. That is, the predetermined antibacterial component is eluted every time it comes into contact with water, but the slightly anti-soluble antibacterial agent 21 is used to elute the desired antibacterial component over a long period of time. It is effective for obtaining a desired antibacterial effect and has an advantage that the antibacterial agent 21 can be used for a long period of time.
なお、抗菌剤21の収容個所は、具体的には流出口13周りに形成した第1の凹所19としているが、該凹所19内に必要な残水量を確保する容積を得るようにすることは可能なので、この場合には台座18周りの残水可能な第2の凹所20は省略することができるなど、種々変形して実施できる。
In addition, although the storage location of the antibacterial agent 21 is specifically the first recess 19 formed around the outflow port 13, a volume that secures a necessary remaining water amount in the recess 19 is obtained. In this case, the second recess 20 capable of remaining water around the pedestal 18 can be omitted, and various modifications can be made.
上記した実施形態では二槽式の洗濯機1の給水経路中に設けた濾過装置2について述べた。この洗濯機1では、一般的に水道水を蛇口9の開閉操作にて給水制御している。
これに対し、給水動作や洗濯運転動作を自動的に行なう洗濯機では、自動的に給水制御できるように例えば電磁式の給水弁を備えている。以下に変形例として、この種自動型の洗濯機の給水経路中に設けた濾過装置について述べる。 In the above-described embodiment, thefiltration device 2 provided in the water supply path of the two-tank washing machine 1 has been described. In the washing machine 1, tap water is generally supplied and controlled by opening and closing the faucet 9.

上記洗濯機33を使用する場合は、蛇口9は開放した状態で洗濯運転が自動的に制御され、従って給水弁35も自動的に開閉制御され、給水開始および給水停止が実行される。このため、給水停止時における給水弁35の上流側である給水経路は高い水道水圧を受けるため、該給水経路は堅固な構成および水密な連結構成が要求される。例えば、上記濾過装置38は、円筒状の流入口39の外周側面には雄ねじ部39aを形成し、流出口40の内周側面には雌ねじ部40aを形成している。
When the washing machine 33 is used, the washing operation is automatically controlled with the faucet 9 opened, and accordingly, the water supply valve 35 is also automatically opened and closed, and water supply start and water supply stop are executed. For this reason, since the water supply path on the upstream side of the water supply valve 35 receives a high tap water pressure when the water supply is stopped, the water supply path is required to have a firm structure and a watertight connection structure. For example, the filtering device 38 has a male threaded portion 39 a formed on the outer peripheral side surface of the cylindrical inlet 39 and a female threaded portion 40 a formed on the inner peripheral side surface of the outlet 40.
そのうち、下部の流出口40は、外周側面に雄ねじ部34aを一体に形成してなる上記給水口34とパッキン41を介してねじ結合されている。一方、上部の流入口39は、これと連結する給水ホース37の下端部に装着されたナット部材42が有する雌ねじ部42aと、パッキン43を介してねじ結合され、ナット部材42の回動操作により緊締された結合状態を得ている。
Of these, the lower outlet 40 is screw-coupled via the packing 41 and the water supply port 34 formed by integrally forming the male thread 34a on the outer peripheral side surface. On the other hand, the upper inflow port 39 is screw-coupled via a packing 43 with a female screw portion 42a of a nut member 42 attached to the lower end portion of the water supply hose 37 connected to the upper inflow port 39. A tight bond is obtained.
なお、この濾過装置38は上記したねじ結合により給水経路と連結する構成に限り、上記実施形態で述べた濾過装置2と異なるのみで、それ以外の内部の濾過機能や抗菌機能を発揮する構成は全て共通としている。従って、高い水道水圧がかかる堅固な給水経路中に設けられた濾過装置38にあっても、ねじ結合により堅固な構成を必要とするが、該給水経路から脱着容易な構成とすることができる。
In addition, this filtration device 38 is different from the filtration device 2 described in the above embodiment only in the configuration that is connected to the water supply path by the above-described screw connection, and the configuration that exhibits other internal filtration functions and antibacterial functions is provided. All are common. Therefore, even in the filtration device 38 provided in a solid water supply path to which high tap water pressure is applied, a rigid structure is required by screw connection, but a structure that can be easily detached from the water supply path can be obtained.
よって、変形例にあっても上記実施形態で述べたと同様の濾過効果および抗菌効果が期待できるとともに、濾過装置38の下流側に配した給水弁35には鉄錆等の不純物の浸入を阻止でき、該給水弁35の動作不良を防止できる効果を有し、この種自動型の洗濯機33にも有効に活用できる。
Therefore, even in the modified example, the same filtration effect and antibacterial effect as described in the above embodiment can be expected, and the water supply valve 35 disposed on the downstream side of the filtration device 38 can prevent the entry of impurities such as iron rust. The water supply valve 35 can be prevented from malfunctioning and can be effectively used for this type of automatic washing machine 33.
また、上記各実施形態では一般家庭用の洗濯機に適用した濾過装置として説明したが、これに限らず、業務用或は工業用の洗浄機器にも実施可能である。その他、抗菌剤の収容ケースは、ケース本体底部に対し別部材の蓋部を開閉可能に被着する構成としたり、或はメッシュ状のかご形状としてもよいし、また抗菌剤を収納した収容ケースをユニット単位として用意し、該ケース毎交換する構成としてもよい。また、抗菌剤を構成するリン酸系ガラスに代えて硼酸系ガラスで構成することも可能である。
In each of the embodiments described above, the filtering device is applied to a general household washing machine. However, the present invention is not limited to this, and the present invention can be applied to commercial or industrial cleaning equipment. In addition, the antibacterial agent storage case may be configured such that a separate lid is attached to the bottom of the case main body so as to be openable and closable, or may be a mesh-shaped cage, or the antibacterial agent storage case May be prepared as a unit and replaced for each case. It is also possible to use boric acid glass instead of phosphoric acid glass constituting the antibacterial agent.
以上、本発明のいくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略,置き換え、変更を行なうことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。
Although several embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
