Description

The filter that washing facility is used

Technical field

Embodiments of the present invention relate to the filter of the washing facility of impurity in a kind of filtered water.

Background technology

Possesses for example electromagnetic type feed water valve as washing machine or the dish-washing machine etc. of washing facility. This feed water valveWater inlet side is connected with outside water source (for example running water). Generally, the water inlet side of this feed water valve peaceMetal filter is housed. This filter is formed as for example per inch 60 meshes, width of mesh 0.24mmThe structure of the mesh specification of left and right, to prevent the immersion of impurity. But, sometimes at water source, from the beginningIn water, be also mixed with impurity. For example, while thering is the supply equipment such as running water pipe and aqua storage tank, follow it oldChange, also can produce the iron rust that is called red rust. If sneaked into the iron rust of such generation, running water can becomeMuddy redness. Such running water is also referred to as red rusting water.

Certainly, use this water capacity that contains iron rust easily to cause the pollution of washings, variable color, or lureSend out the generation of washing iron rust in cell body or water flowing path. Further, if iron rust is stacked into feed water valveInside, also may cause fault. In addition, iron rust has all size, for example, count the small iron in μ m left and rightRust also can be sneaked in running water sometimes in a large number. The general filter that above-mentioned feed water valve has, cannot filter thisPlant small impurity.

In addition, for utilize the water storage sources such as water for bathing as external water source with water saving, utilize supply-water pump supply waterMany with the situation as washings. In this case, use the water capacity that contains the impurityes such as iron rust easyCause pollution or the variable color of washings, and then easily bring out washing with iron rust in cell body or water flowing pathProduce. And, if iron rust is stacked into feed water valve inside, also may cause fault.

Thus, provide structure as disclosed in Patent Document 1: for example, at the feed water valve of washing machineUpstream is surveyed the filter with filter material is set, and this filter material is made up of lamellar material.

But the filter material filtering as general water flowing, is to use a lamellar material, single substantiallyThe lamellar material of layer. Like this, although it is good to simplify fixing means and the water flowing of filter material,Be on the other hand, only can make small especially impurity be easy to pass through with a lamellar material. And,The mesh size of filter is determined by the mesh of the material using, thereby impurity filtering function is limit by materialMake and become dull. That is to say, mesh changes according to used material, causes the merit of filterCan be unstable, even, the mesh size of material may cause mesh blocked state in advance.

On the other hand, if will use from the water of the storage water source supplies such as the water for bathing of external water source by supply-water pumpMake washings, can using water wisely, and can expect the good washing being brought by warm water for bathingEffect. Therefore, this washing machine of supply-water pump that utilizes is also extensively universal. Then, as patent documentation 2Disclosed, as the filter of water for bathing, occurred for example utilizing whirlwind separator etc. withRemove the structure of impurity.

In addition, also can consider following structure: while using supply-water pump, possess attached at the leading section of water supply pathThere is the water sucking mouth of filter, and this water sucking mouth is put in bathtub. But, for fear of occurring in advanceMesh stops up, and the filter of this water sucking mouth generally does the structure that ramify is sparse. Therefore, cannot bring into play and fillThe filtering function dividing. In addition, the impurity containing in water for bathing has varied from big to small. Therefore,The filtering function that cannot play stably. And, use water for bathing easily to produce miscellaneous bacteria, and miscellaneous bacteria is to causeThe major reason of washings jaundice or undesirable stink, therefore, is used water for bathing to need as washingsTo further improve reliability.

In addition, in this filter, the impurityes such as the iron rust that laminar filter material is in use caughtWhile causing mesh blocked state, its water flowing significantly reduces than usual. Therefore, for filter is sent outWave the filtering function of expection, impurity catch effect become insufficient before, need to carry out by exampleAs the impurity that method for washing is caught filter material is removed, or be replaced by the disposal such as new filter material. Therefore, needWant one to use structure more easily, the easy dismounting of for example filter material is in filter and can pacify reliablyThe structure of dress and maintenance filter material etc.

Detailed description of the invention

Below, with reference to the accompanying drawings of multiple embodiments. Further, identical to essence in each embodimentKey element is given same-sign, and description thereof is omitted.

(the first embodiment)

Below, referring to figs. 1 through Fig. 5, illustrate filter for washing facility, i.e. washing machine and profitThe first embodiment with running water as external water source.

Fig. 2 represents the stereoscopic figure of the use state that uses the filter in washing machine, attached to thisThe overall structure of the washing machine representing in figure etc. is summarized. The main body 2 that forms washing machine 1 gabarit is by closelyLike the outer container 3 of rectangular box shape and form with the mode top cover 4 mounted thereto that covers its upper face side.The front part of this top cover 4 possesses guidance panel 5, and the substantial middle portion of top cover 4 is provided with covers 6, for openingClose the input port of not shown washings. Top cover 4 can pass through the not shown cell body of this input port to insideDrop into and take out washings. And then, at the rear portion of top cover 4, be provided with highlightedly upward for to grooveThe feed water inlet 7 that body supplies water. Detailed content about this feed water inlet 7 describes in detail subsequently.

As general structure, cell body is by stirring body, rotatable cellular swivelling chute and capable of storing waterBe configured in swivelling chute tank around and form. The washing machine 1 with this cell body substantially all possesses automaticallyCarry out the function of each processes such as washing stroke, rinsing stroke, dehydration stroke. In order to supply with from outside waterSource is the water of tap 8, on feed water inlet 7, be communicated with hose coupling 9, flexual water supply hose 10,And the detailed content filter 11 for filtered water impurity described later. Filter 11 is arranged onFrom external water source to feed water inlet in 7 water supply path. Further, tap 8 is conventionally also referred to as " water bolt ".

Fig. 3 is the exploded perspective view that more specifically represents the part-structure of water supply path, particularly representsThe structure of the linking portion of the water supply path that filter 11 possesses. First, feed water inlet 7 is described,This feed water inlet 7 is formed as from outstanding cylindric of top cover 7. On the peripheral part of this feed water inlet 7, be integrally formedThere is external thread part 7a, metal filter 12 is installed in the interior perimembranous of feed water inlet 7. This filter 12Be used for preventing that impurity from immersing washing machine 1 inside. Further, on the base portion of the peripheral part of feed water inlet 7, installResilient annular seal ring 13. Sealing circle 13 is for preventing between filter described later 11Linking part leaks. This feed water inlet 7 is directly attached to the not shown confession that is arranged on top cover 4 rear sideThe water inlet side of water valve. Or this feed water inlet 7 is integrally formed in the water inlet side of feed water valve. Like this withThe feed water valve that feed water inlet 7 is communicated with can be undertaken by the private water supply path in cell body from this delivery port sideSupply water.

Then, filter 11 is attached between feed water inlet 7 and water supply hose 10. This filter 11Possess: filter housing 14, it is large diameter cylindric that face shaping is; Inflow entrance 15, on the top of filter housing 14Be diameter and be less than the cylindric of filter housing 14; Flow export 16, is diameter in the bottom of filter housing 14 and is less than filter housing14 cylindric. In the lower side of this filter 11, flow export 16 is connected with feed water inlet 7. Flow outOn mouthfuls 16 tubular inner peripheral surface, be formed with internal thread part 16a, the external thread part 7a of feed water inlet 7 screws in that this is interiorThreaded portion 16a. Thus, in the lower side of filter 11, flow export 16 and feed water inlet 7 are by theseThreaded portion 7a, 16a are able to combination. Now, because sealing ring 13 is compressed, flow export 16 and feed water inletFormation watertight links.

On the other hand, in the upper side of filter 11, on the outer peripheral face of inflow entrance 15, be formed with outer spiral shellThe 15a of line portion. And the nut member 17 that is arranged on water supply hose 10 bottoms possesses the double cylindrical-opening portion of doingInternal thread part 17a and there is integratedly the 17b of rotatable handle portion of this internal thread part 17a. FilterThe external thread part 15a that installs 11 tops screws in this internal thread part 17a. In this case, linking filtrationDevice 11 is under the state of washing machine 1, and the nut member 17 that flexual water supply hose is possessed is rightThe top position of accurate external thread part 15a, and then in conjunction with external thread part 15a and internal thread part 17a. This feelingsUnder condition, that on the base portion due to the peripheral part of inflow entrance 15, installs has flexible annular seal ring 18 quiltsCompression, thereby inflow entrance 15 links with watertight state with nut member 17. Therefore, filter11 have realized at the bound fraction of helicitic texture the connecting structure that forms watertight state and can carry out dismounting.

Then, about the concrete structure that is connected to the filter 11 in water supply path as above, rootAccording to the filter 11 shown in profilograph and the Fig. 4 of the filter 11 shown in Fig. 1Exploded perspective view describes. The filter 11 that Fig. 1 (a) represents to be installed on washing machine 1 before useState in the first half, Fig. 1 (b) is the overall diagram that represents the use state of filter 11. At this,With reference to Fig. 1 (b), mainly overall structure is described, the effect of use state etc. is described afterwards. First,Filter housing 14 is made up of the member of two ester mouldings, that is to say, by having bottom tube-like and cylindrical vessel shapeShell main body 19 and forming to cover the cover 20 that the mode of its upper surface arranges. Further, shell main body at leastThe 19th, formed by transparent resin material, make to have an X-rayed inside. For example, as transparent resin material,Use acrylonitrile-styrene resin, polycarbonate resin, acrylic resin etc.

In the bottom center of shell main body 19, be provided with integratedly the flow export outstanding from the bottom of shell main body 1916. In addition, in bottom center and the private side of flow export 16 in opposition side of shell main body 19, oneBe provided with the outstanding for example cylindrical wall cylindraceous portion 21 from the bottom of shell main body 19. This cylindrical wall portion 21Outstanding upward in Fig. 1, be formed on flow export 16 in concentric position. Due to this cylindrical wall portion21 diameter is less than flow export 16, is formed with to radially in the boundary portion of cylindrical wall portion 21 and flow export 16The end difference that extend inner side. There is flexible sealing ring 22a and be arranged on this end difference. Thus, in Fig. 3When the flow export 16 illustrating is attached to feed water inlet 7, sealing ring 22a is on leading section and the rank of this feed water inlet 7Compressed between ladder portion. On the top of shell main body 19, be formed with the openend that is for example cylindric opening.On the inner peripheral surface of this openend, form internal thread part 19a.

On the other hand, cover 20 is formed as the dish type of shell main body 19 side openings. The central portion of cover 20, oneBody ground forms top in digraph 1, the i.e. outstanding inflow entrance 15 to outside. In addition, the periphery of cover 20On end face, form external thread part 20a, for screwing in the internal thread part 19a of shell main body 19. AcrossSealing ring 22 links these internal thread parts 19a and external thread part 20a, thus can be by shell main body 19 and cover20 carry out watertight link, and can form the structure of dismantled and assembled shell main body 19 and cover 20.

As shown in Fig. 1 (b) and Fig. 4, like this form filter housing 14 in, contain filter core member 23,Filter material 24 and holding plate 25. Filter core member 23 is the state quilts that are erected at the bottom center of shell main body 19The cylindrical structural member of supporting. Filter material 24 remains on the outside of filter core 23, is included in water for removingImpurity. Holding plate 25 is the modes to cover these filter core members 23 and filter material upper surface from topThe disc-shaped component of installing. Further, the top of filter core member 23 and filter material 24 not only refers to these filter coresDirectly over member 23 and filter material 24, as long as the position higher than filter core 23 and filter material 24 at least, alsoComprise from directly over the position of departing from a little.

Further describe particularly, filter core member 23, on the almost whole surface of its perisporium, formsHave and be for example cancellate multiple reach through hole 23a. Filter core member 23 forms by multiple reach through hole 23aThe structure that water flowing is good. The filter core member 23 of this drum is formed as diameter than in shell main body 19The cylindrical wall portion 21 that bottom center is outstanding is larger. Filter core member 23 by be fitted to cylindrical wall portion 21 fromAnd supported by cylindrical wall portion 21 with upright state. , cylindrical wall portion 21 is as dismantled and assembled at assigned positionAnd with the member of upright state supporting filter core member 23, play the effect of so-called align member.

Filter material 24 can be the cloth that can overlappingly be wound on filter core member 23 peripheral parts, such cloth,For example comprise all materials such as friperie, the shirt of not wanting or underwear, stocking, towel. Will be for example thanThinner cloth cut into figure in height dimension, filter core member 23 length dimension on an equal basis size,And the cloth multiple-layer overlapped of cutting is wound on filter core member 23, thereby form filter material 24. Form filter materialThe number of plies of 24 cloth, the overlapping coiling number of times of cloth can be for example 9 layers of left and right.

About this filter material 24, with further reference to Fig. 5 (a) and (b) of overlapping coiling order that show filter materialDescribe. That is, as shown in Fig. 5 (a), according to the length dimension of filter core member 23, in other words alongThe size of height dimension, and the required total length of overlapping coiling, cut off the cloth that forms filter material 24. Then,The cloth of cut-out is spread out on smooth suitable table top for subsequent use. Then, filter core member 23 is configured in to thisThe top side of cloth, rotates and is wound around towards the direction of arrow in figure, thereby wraps into this filter core member 23 with clothOuter peripheral face. Then, on the cloth of revolution winded filtering core member 23, further which floor cloth of overlapping coilingMaterial is taking package as multilayer shape. Fig. 5 (b) represents to have reeled the state of specific length cloth. Due to filter material 24Overlapping coiling cloth and forming, thus incrust, and consequently, filter material 24 can be rolled up with multilayerThe state of dress remains on cloth as the filter core member 23 of core around. So carry out the overlapping of clothIn the situation of reeling, be preferably upper end and the bottom of the end face alignment filter core member 23 of cloth are carried outOverlapping coiling, thus avoid a part for cloth outstanding from upper end or the bottom of filter core member 23.

Like this, as shown in the exploded view of Fig. 4, keep the filter core structure of the state of overlapping multilayer-wound filter material 24Part 23, is housed in and takes off cover 20 to open shell main body 19 inside of upper surface. Be specially, make to formThe bottom of the filter core member 23 of filter material 24 cores is entrenched in cylindrical wall portion 21. As shown in Fig. 1 (b),Due to and cylindrical wall portion 21 between have some gap S1, thereby can easily embed this filter core member 23.Thus, obtain the property easy to assemble of filter material 24. In addition, for example, the height dimension design of cylindrical wall portion 21Become, can be with difficult drop-off and the crooked chimeric filter material 24 of state support.

Consequently, the filter material that comprises filter core member 23 24 can be stabilized in to the collecting position of regulation,And keep with upright state. In this case, the diameter of filter material 24 be can guarantee cylindricBetween the inner peripheral surface of the outer peripheral face of filter material 24 and shell main body 19, there is the size of sufficient room. In addition, cylinderBetween the inner peripheral surface of the periphery wall of shape wall portion 21 and the lower surface of filter core member 23, produce gap S1. ButThat the weight of the whole filter material 24 by comprising filter core member 23, makes the lower surface of filter core member 23Be close on the inner bottom surface of shell main body 19, thus, gap S1 can not pass through the bottom of filter core member 23Arrive continuously the outside of filter core member 23.

Like this, the structure being formed by filter material 24 and filter core member 23 is housed in shell main body 19. SoAfter, under this state, holding plate 25 is arranged on to the structure being formed by filter material 24 and filter core member 23On. Herein, the structure of this holding plate 25 is described. The basic structure of this holding plate 25 is oneGround possesses main part 26 and supporting teat 27. In main part 26 surfaces, upper surface is smooth, entiretyOn be formed as discoid. Supporting teat 27 is formed on the central portion of main part 26 rear side, isCircular. Further, supporting teat 27 can be for example cylindric, can be also cylindric. With shell masterBetween the bottom of body 19 bottoms, cylindrical wall portion 21 and filter core member 23, be formed with the chimeric of gap S1State is same, between the inner peripheral surface of the upper end of supporting teat 27 and filter core member 23, be formed with some betweenGap S1. Holding plate 25 is installed under this bearing state. But, because gap S1 is gap radially,In the situations such as a side departs from, can cause the inhomogeneous situations such as the local change in gap is large at such as holding plate 25.Under this bearing state, the rear side of the main part 26 of holding plate 25 abuts to one of filter core member 23End, i.e. upper surface. Abut to the normal mounting shape of filter core member 23 upper surfaces at the back side of holding plate 25Under state, as shown in Fig. 1 (b), holding plate 25 is supported with level.

Further, except above-mentioned basic comprising, particularly as shown in Figure 4, holding plate 25 also possesses manyIndividual jut 28. Horizontal surface that these juts 28 have at the main part 26 of holding plate 25, go upSurface, is radiated entends from the central part of main part 26 respectively. Jut 28 except with cover 20Position beyond the opposed centre of opening of inflow entrance 15 is formed as radial and is formed as respectively plateThe shape that shape is outstanding. Further, these radial juts 28 receive the water flowing into from inflow entrance 15,And the flow direction of this water is distributed to peripheral direction equably, afterwards its effect is elaborated. Therefore,Jut 28 is not limited only to tabular, can be the cross section of for example chevron, or can not be also continuously prominentThe shape rising. , jut 28 can carry out various distortion.

The holding plate 25 of said structure is installed on filter core member 23 and is housed in shell main body 19 itAfter, at the upper surface open mounting cup 20 of shell main body 19. Be specially, between shell main body 19 and cover 20Arrange under the state of sealing ring 22, in conjunction with external thread part 20a and internal thread part 19a. Thus, formedLink the filter housing 14 of the hollow container shaped of shell main body 19 and cover 20 with watertight state. Form thus inner toolThe filter 11 of the filtering function of standby filter material 24 grades. Then, as shown in Figure 2, by as above pacifyingFill this filter 11, form the water supply path of the feed water inlet 7 from tap 8 to washing machine 1.

Further, in Fig. 2, be to be directly attached to the water supply that is built in main body 2 by the key element that symbol 43 representsThe pump of pump 44 is used feed water inlet. This pump be arranged on feed water inlet 43 top cover 4 rear portion with feed water inlet 7 phasesRight position, describes in detail subsequently to this. Another feed water inlet 7 be equivalent to feed water inlet that so-called running water pipe uses,It is the feed water inlet that running water is used.

Next, the effect that uses the filter 11 in the washing machine 1 of said structure is described.

Open the tap 8 at water source, operating operation panel 5, sets the working procedure of expecting and brings into operation,Washing machine 1 is controlled by not shown control device, thus, for example automatically performs washing stroke, floatsWash the operation such as stroke, dehydration stroke. At this, the water supply action in washing stroke is described, 1 dozen of washing machineOpen not shown feed water valve, from the running water of tap 8 through water supply hose 10, filter 11 withAnd be positioned at feed water inlet 7 of feed water valve upstream side etc., be supplied to the interior not shown cell body of main body 2.

Then, describe the effect of filter 11 in this water supply action in detail. First, filter with reference to representingFig. 1 (b) of device 11 use state describes, from tap 8 flow through water supply hose 10 fromWater, flows in filter housing 14 from the inflow entrance 15 of filter 11. The water of this inflow has and Fig. 1(b) in the inflow direction vertical plane shown in arrow A to surperficial holding plate 25 places received. Thus,The water flowing into is changed it and is flowed to, as shown by arrow B, and along the i.e. laterally outwardly all side flow of horizontal direction.Further, the surface of holding plate 25 is not limited to vertical with the inflow direction of water, can be also the stream with waterInbound tilts a little.

Then, the surface of holding plate 25 possesses the radial jut that You Cong center side direction outer circumferential side extends28. Therefore,, by these juts 28, be subject on one side by all along the current radially shown in arrow BThe effect that is distributed to circumferencial direction is flowed evenly on one side. And holding plate 25 is to cover filter material 24 from topThe mode of upper end is installed, and the pressure of the water being flowed into, thereby performance is pressed the back of the body from topThe filter core member 23 of face side and the effect of filter material 24. Thus, holding plate 25 stops water from filter effectivelyThe end face side inflow of material 24. Further, even if in the situation that holding plate 25 tilts a little, by this maintenanceThe water that plate receives also can disperse equably by the jut that is radiated entends. In addition, even if holding plateIn situation about tilting, because this holding plate has received the pressure of the water flowing into, thereby also can bring into play from topPress the filter core member of rear side and the effect of filter material.

Then, towards the water of Radial Flow, as shown by arrow C, from the outer circumference end of holding plate 25 along filter housing14 inner peripheral surface flows to below. Then, flow to below part that water in filter housing 14 makes filter material 24 inImpregnation state. Now, because the internal structure of filter material 24 is the states of being close to of overlapping multilayer-wound cloth,The water flowing down is stopped by filter material 24, cannot directly pass the inside of filter material 24. Further, work as currentEnter in filter housing 14, thereby this water is supplied to the white space of wherein filling up filter housing 14, thus, filter housing 14Inside reach rapidly or gradually full water state.

Consequently, it is large that tap water pressure in filter housing 14 becomes, the water being under pressure as shown by arrow D,Flow through from water through filter material 24. Be specially, water is from the inner filter core member of periphery process of filter material 2423 reach through hole 23a flows into central side. Then, the water of inflow as shown by arrow E, passes through filter housing 14Wall portion tubular 21 and the flow export 16 of bottom, be supplied to the feed water inlet 7 of washing machine 1. Then, be supplied toThe water of feed water inlet 7 is supplied in cell body by not shown feed water valve. As mentioned above, supply from tap 8The water of giving is all filtered when by filter material 24. Thus, can remove cannot be by the water that enters of feed water valveThe impurity that mouth side, the filter 12 that feed water inlet 7 has are conventionally removed. In addition, even if at running waterIn sneak in the situation of small iron rust, also can effectively remove this iron rust. Therefore, can mix having filteredThe clean water of thing is delivered to the feed water valve and the cell body that are positioned at filter 11 downstreams.

In addition, holding plate 25 stops water from the upper end of filter material 24, end face cylindraceous flows into. SeparatelyOutward, the current that flow into towards arrow A are converted to the arrow B vertical with this arrow A direction by holding plate 25Direction, the outer circumferential side of the filter material 24 in guiding current direction downstream. Thus, flow into the water of filter housing 14 insideCan flow to inside from the outer circumferential side of filter material 24 cylindraceous, thereby can obtain being filtered by filter material 24Suitable current. , filter 11 can be brought into play effective filtration. Further, holding plate 25There is the effect of pressing filter material 24 upper ends. Thus, even if for example at the overlapping volume of the cloth of filter material 24Around do not have alignment situation under, also can press from top this unjustified cloth, thus can eliminate because ofCloth carries out overlapping coiling and the undesirable condition that causes unjustifiedly.

Below, illustrate its example. The reason of the unjustified and overlapping coiling of cloth for example has, as Fig. 5(b), shown in, cannot correctly overlapping being wound on filter core member 23 of cloth of filter material 24 will be formed. ExampleAs, even if make the length dimension of cloth and the length dimension (height dimension) of filter core member 23 in the same size,Manual carry out overlapping coiling in the situation that, the part that multiple-layer overlapped is wound on cloth cylindraceous sometimesOutstanding from end. Filter material 24 about the state that a part for this cloth is protruded to top was arranged onThe situation of filter in device 11, Fig. 1 (a) will use state before this filter 11, supplyHydrodynamic(al) is made previous state and is represented as an example. That is to say, be the upper end of filter material 24 cylindraceousUnder the outstanding unjustified state of portion, holding plate 25 is lifted to higher than normal installation site. Like this, originallyThe upper surface that is bonded on the filter core member 23 at holding plate 25 back sides to be close to state becomes unsteady, is keepingBetween the upper surface of the back side of plate 25 and filter core member 23, produce the gap S2 of above-below direction.

Gap S1 between this gap S2 and filter core member 23 and supporting teat 27 is in connected state.In addition, sometimes between the upper surface and holding plate 25 of filter material 24, in fact do not produce above-below directionGap is for well, but sometimes irregular or be formed with discontinuously gap S3. And, the front portion of this gap S3Be connected with gap S2, S1. Then, the water flowing resistance by these gaps S3, S2, S1 significantly lower thanBy the water flowing resistance of filter material 24. The water of, filling in filter housing 14 more easily passes through than filter material 24Gap S3, S2, S1.

Keep in the situation of this state water supply start action, once water is filled in filter housing 14, as arrow GShown in, water starts to flow into by gap S3, S2, S1, and water is subject to tap water pressure and from filter material originally24 outer peripheral face side is passed through, thereby all water is effectively filtered. In this case, the distribution of gap S3Easily expand to horizontal direction, thereby cause the flow channel shown in arrow G to expand to circumferencial direction.

Owing to being subject to the pressure of running water, the water flowing into towards arrow G direction makes one of outstanding cloth on one sidePart distortion flows on one side. Therefore, even if discontinuous gap S3 is originally accompanied by current and is out of shape,Thereby force to form continuous clearance channel. Then, the private side of this Yu gap, path, gap S3 is continuousGap S2, S1 in connected state, thereby these gaps S3, S2, S1 are connected and form gap roadFootpath. Then, water flows into by these paths, gap, the water flowing into by path, gap core component after filtration23 hollow bulb flows out to the outside of filter 11. That is to say, filter 11 cannot be to passing throughThe filtration that the script of the impurityes such as iron rust is removed in the water performance that flow out in path, gap, probably causes comingDirectly be supplied to washing machine 1 through supply-water pump from the water filtered at water source.

, owing to having the surface relative with arrow A, the main part 26 of holding plate 25 directly bearsThe mobile hydraulic pressure of the running water of flow arrows A direction. Thus, press the pressure of the direction of this holding plate 25Act on holding plate 25. Like this, even if exist outstanding in a part for cloth that forms filter material 24Part, this ledge is also kept plate 25 and presses. That is to say, press the power effect of holding plate 25In the direction of dwindling gap S3, also act on the direction of the gap size that dwindles gap S2. Therefore, energyEnough eliminate these gaps S3, S2.

Describe according to Fig. 1 (b), after eliminating gap S2, S3, can effectively carry out the mistake of waterFilter effect. And, can, from the outside of transparent shell main body 19, detect by an unaided eye by impurityes such as iron rustThe pollution condition of the filter material 24 causing, thus can easily judge replacing period of filter material 24. Further,Overlappingly be involved in the unjustified situation of end face that cloth causes filter material 24, can occur too in bottom. ButThat in this case, nearly all weight of filter material 24 is all added in the outstanding position in filter material 24. CauseThis, if filter material 14 is housed in to the assigned position in filter housing 14, can maintains and not produce gapSuitable state.

On the other hand, Fig. 6 and Fig. 7 represent the variation about holding plate 25. Fig. 6 (a) is holding plate25 stereoscopic figure, Fig. 6 (b) is the cutaway view of holding plate 25. This variation is at holding plate 25On be provided with concavity portion 29. This concavity portion 29 is forming the surperficial central portion of tabular surface of main part 26,Recessed circular shape. This concavity portion 29 is formed on the concentric position corresponding with the supporting teat 27 of rear sidePut. Thus, as shown in Figure 1 (a), (b) shows, holding plate 25 is installed under the state in filter housing 14,Concavity portion 29 is opposed with inflow entrance 15. In a word, concavity portion 29 is formed on direct reception from inflow entrance 15The position of the water flowing into.

According to this structure, the water flowing into from inflow entrance 15 is in the received situation of tabular surface of holding plate 25Under, it directly disperses to horizontal direction. But the water flowing into from inflow entrance 15 is connect in concavity portion 29In situation about receiving, because forming resistance, the internal perisporium portion of this concavity portion 29 stops this water, thereby canImprove the hydraulic pressure that holding plate 25 is subject to according to tap water hydraulic. Like this, owing to having promoted to press holding plate25 effect, thus can make reliably holding plate 25 and filter core member 23 chimeric. In addition, Ke YitongCross holding plate 25 and press the upper end of filter material 24 with stronger pressure, thus can more effectively suppress asThe gap S3 that being easy to shown in Fig. 1 (a) produces.

On the other hand, Fig. 7 (a) and (b) represent different variation. This variation is possessing basic structureHolding plate 25 in, in the periphery of main part 26, formed the perpendicular wall portion 30 erectting upward. Pass throughForm this perpendicular wall portion 30, holding plate 25 has concavity portion 31 on its all surfaces. Further, now,Radial jut 28 is removed.

According to this structure, once receive water in concavity portion 31, the perpendicular wall portion 30 of its peripheral part forms pointThe resistance of aproll is to stop this water. Therefore, holding plate 25 can improve reception by the hydraulic pressure of running waterHydraulic pressure. Like this, the effect of holding plate 25 be can promote to press, holding plate 25 and filter core structure made reliablyPart 23 is chimeric. In addition, can press by holding plate 25 upper end of filter material 24 with stronger pressure,Thereby can more effectively suppress the gap S3 that being easy to as shown in Fig. 1 (a) produces. Further, at thisIn variation, owing to having formed large diameter concavity portion 31 on the almost whole surface of main part 26, because ofAnd can expect all to carry out the stable effect of pressing instead of deflection holding plate 25 for holding plate 25The effect of pressing of a part. In addition, because the internal capacity of concavity portion 31 is large, thereby can receive largeThe water of amount, under the pressure of running water, can be increased and be pressed guarantor by the further w of the weight loading of large water gagingHold the effect of plate 25.

As described above, according to the first embodiment that filter 11 is used in to washing machine 1,Can expect following effect.

Conventionally,, at the feed water valve upstream side of washing machine 1, be provided with the mistake for removing the impurityes such as iron rustFilter device 11. Thus, can avoid the feed water valve fault that causes because of sneaking into of impurity or the product of iron rustRaw, in addition, also can solve the problem such as pollution and variable color of washings. And, can increase and can useThe free degree at water source, is not used the water resources situation restriction of region and is effective as washings utilization.

Then, filter 11 is housed in filter material 24 in this filter housing 14. This filter material 24 is by cloth weightFold and be wound into tubular, and remain on filter core member 23. In addition, filter 11 possesses discoidHolding plate 25. This holding plate 25 is supported in the top of filter core member 23, covers filter material 24 from topUpper surface. This holding plate 25 directly receives and flows into the water of filter housing 14, and changes outside current are distributed toZhou Fangxiang. Thus, holding plate 25 makes water lead to central side from the outer peripheral face side of filter material 24, effectively shortEnter filtering function. And holding plate 25 is covered with filter material 24 from top. Like this, can anti-sealing directly fromThe upper end side of filter material 24 flows into.

Filter material 24 forms by overlapping multilayer-wound cloth, thereby can carry out as expanded its filter areaEtc. suitable adjustment. In addition, by this filter material 24, can effectively remove the small impurityes such as iron rust.In addition, as the kind of cloth, can be widely used various clothes. In addition, can free adjustment clothOverlapping coiling amount. Therefore,, as cloth, can freely select to utilize such as shirt or friperie etc. allThe cloth that each families such as clothes, stocking, towel have. Therefore, there is no need to use ion-exchangeThe high price such as resin is difficult for the filter material obtaining. Like this, filter material 24 can utilize handy cloth to form,And can realize at an easy rate. Therefore, can provide simple and easy and filter 11 easily.

In addition, because the main part 26 of holding plate 25 has the table in the face of the arrow A direction shown in Fig. 1Face, thereby can directly receive the mobile hydraulic pressure of the running water mobile along arrow A direction. Like this, downwardTrip side is pressed pressure-acting in the direction of this holding plate 25 in holding plate 25. Thus, can maintain filterCore component 23 is suitably entrenched in the state on holding plate 25. In addition, even the cloth of overlapping coilingA part is outstanding from the end face of filter material 24, the maintenance arranging to cover the mode of filter material 24 from topPlate 25 also can be pressed into. Like this, can dwindle and even eliminate the space being represented by gap S3, therebyCan flow into by gap S3 by anti-sealing. In other words, can obtain from the outer peripheral face of the filter material 24 of tubularThe current that side direction central side is mobile, namely carry out by filter material 24 water effectively filtering, thereby effectivelyUtilize filter material 24 entirety.

Directly receive the holding plate 25 that flows into the water in filter housing 14, forming the main part 26 of flat conditionSurface, possesses the jut 28 that is radiated entends from central side towards outside. Like this, can water is evenBe distributed to peripheral direction, inhibitory action is in the deflection of hydraulic pressure or the current of holding plate 25. Therefore, can notProduce eddy current etc., can form current smoothly.

On the other hand, in the filter housing 14 of accommodating filter material 24, use based on external thread part and internal thread partEasy-disassembling-assembling connection unit, as the unit in conjunction with shell main body cylindraceous 19 and cover 19. In addition,About filter material 24 and holding plate 25 are accommodated to the filter core member 23 that remains on assigned position, also utilize and be easy toThe bearing unit of dismounting, adopts the knot that is fitted to the cylindrical wall portion 21 of shell main body 19 bottoms across gap S1Structure. Thus, user can change the dismounting operation of filter material 24 grades simply and easily.

And, as the means of replacing time that judge this filter material 24, form shell with transparent resin materialMain body 19, thus can easily confirm the pollution condition of the filter material 24 being caused by impurityes such as iron rust from outside.Therefore, the pollution situation causing according to the water source situation by region, replaceable filter material and do not miss it moreChange period, thereby can maintain suitable water supply action and the effective filtration for impurity. ButBe, be not limited to only shell main body 19 is made as to transparent structure, for example, filter housing 14 all can be made asBright, the scope that can have an X-rayed inner partially transparent also can be set.

On the other hand, the different distortion example shown in Fig. 6 and Fig. 7, all flows in filter housing 14 receivingThe holding plate 25 of water is provided with concavity portion 29,31, for stopping that current are at once to peripheral direction, horizontalDirection is disperseed. By these concavity portions 29,31, strengthen the effect of block water, thereby can improve guarantorHold the hydraulic pressure that plate 25 receives. Thus, can strengthen the effect of pressing holding plate 25, make reliably holding plate25 and filter core member 23 chimeric. In addition, can press filter material 24 with stronger pressure by holding plate 25Upper end, thereby can more effectively suppress the generation of gap S3. Therefore, can effectively be carried outFilter required current. Particularly, in the variation shown in Fig. 7, can all bring into play holding plate 25The stable effect of pressing. In addition, owing to receiving, the internal capacity of water is large, thereby can be by block waterWeight further promotes the effect of pressing.

Further, holding plate 25 and filter core member 23 are assembled by different component respectively, but are not limited to this,For example holding plate and filter core member also can form one. In this case, can unify and enter easilyThe dismounting operation of row holding plate and filter core member.

(the second embodiment)

Fig. 8 and Fig. 9 represent the second embodiment. Further, Fig. 8 is the figure that is equivalent to Fig. 1 (b), figureThe 9th, be equivalent to the figure of Fig. 4.

Filter 11 remains on filter material 24 outside of filter core member 23. And filter 38 will be filteredMaterial 32 remains on filter core member 33 inside. Filter core member 33 and holding plate 34 have following architectural feature.

First, filter core member 33 is formed as the large diameter form that has round-ended cylinder shape. Filter core member 33On perisporium, be formed with multiple cancellate reach through hole 33a. The diapire central portion of filter core member 33 is formed with circleThe 33b of hole portion of shape. The 33b of this hole portion is entrenched in the cylindrical wall portion 36 of shell main body 19 bottoms removably.Further, cylindrical wall portion 36 is the outstanding height of tubular lower than cylindrical wall portion 21. Its reason is, due to filter coreMember 33 has large diameter wide lower portion, so even if the height of cylindrical wall portion 36 is lower, it is not yetCan topple over and be supported. Therefore, in order to load in the assigned position of filter core member 33 and to support,As long as form the 33b of hole portion and cylindrical wall portion 36 tablings state, at least avoided the shape of deviation positionState. Therefore, the thickness of cylindrical wall portion 36 is that the thickness degree of filter core member 33 bottoms is enough.In this case, cylindrical wall portion 36 is as the location structure of the collecting position supporting filter core member 33 in regulationPart and significant.

Then, holding plate 34 possesses from the peripheral end of discoid main part 37 prominent integratedly downwardsThe circular supporting teat 35 going out. Thus, holding plate 34 can chimericly be bearing in filter core member 33One end of tubular, i.e. upper end. , supporting teat 35 has larger than the external diameter of filter core member 33Internal diameter, and and filter core member 33 between there is gap S1. Thus, holding plate 34 is torn open being easy toThe state of dress is chimeric and be bearing on filter core member 33.

On the other hand, filter material 32 is forms of overlapping coiling cloth itself, preferably uses as far as possible long sizeCloth. But, even if short cloth, also can be by supplementing at any time cloth with by its overlapping being wound intoMultilayer, thus the large diameter cylindric filter material 32 of the radial dimension with expection can be formed. Further,Supplement at any time many clothes to form in the situation of filter material 32, radial dimension is preferably as far as possible not at filter coreThe inner degree that produces gap of member 33.

Further, the arrow A shown in Fig. 8 to arrow E represents water (flow) direction, in its expression and Fig. 1 (b)The current that the current that represent with prosign are identical in fact. Further, in this case, flow path isThe water inner filter material 32 of flowing through after by filter core member 33, in this, itself and above-mentioned embodimentCurrent difference. In addition, because the central part of filter material 32 is ends that cloth roll gets around the beginning, so cloth itBetween overlapping situation, degree of being close to is less. Like this, as shown by arrow D, at the water of filter material 32 central partsHave the tendency of stream downwards, therefore, as shown by arrow E, water flows out swimmingly from the flow export 16 of below.

According to this embodiment, filtering function, holding plate 34 and filter core member 33 based on filter material 32Deng basic function, as all functions of filter 38, identical with the first embodiment in fact.But, because filter material 32 is housed in to the inside of filter core member 33, covered by holding plate 34 so formThe upper surface of filter material 32 and the form of being surrounded the lateral surface of filter material 32 by filter core member 33. Like this, heavyFolded filter material 32 of reeling can be not at random. Further, each formation of exploded representation filter 38 in Fig. 9Part. Filter material 32 grades are arranged in filter housing 14 and are set in the situation of serviceable condition, ifIn advance filter material 32 is accommodated under the state remaining in filter core member 33, is housed in shell main body 19,Can more easily carry out the assembling operation of filter material 32 and filter core member 33.

Further, in each embodiment described above, all adopt filter material is remained on to filter core memberStructure. But the various distortion that can carry out that such as obstructed filtration core component keeps etc. or expansion comeImplement.

Figure 10 is the figure that is equivalent to Fig. 1 (b) that represents other embodiments. This filter 39 will be realThe filter material identical with the filter material 32 illustrating in example the second embodiment as shown in Figure 8 in matter, only by clothExpect the filter material 32 that overlapping coiling forms, directly mounting is housed in the shell main body 19 that does not use filter core member.In this case, filter material cylindraceous arranges with the state of overlapping coiling cloth, and utilizes and pass throughMultiple-layer overlapped coiling cloth and the weight that forms load with upright state. Therefore, about having loaded filterThe bottom of the shell main body 19 of material 32, the limbers 19b of the flow export 16 below central portion only has connectionBe opening, the bottom surface of shell main body 19 is formed as smooth bottom surface.

To cover the holding plate 40 of the planar disc that the mode of these filter material 32 upper ends arranges from top, flat with itThe back side of smooth shape is bonded under the state of filter material 32 upper surfaces by mounting supporting. Further, holding plate 40The central part at the back side is formed with outstanding protuberance 41 a little downwards. This protuberance 41 is inserted into filter material 32The end that starts to reel, the i.e. gap etc. of central part, prevent that holding plate is inclined to one side for the position of filter material 32 thusFrom. Other the structures that relate to filter housing 14 etc. are identical with the respective embodiments described above.

According to this structure, supplying water when action, holding plate 40 receive as shown by arrow A from inflow entrance15 water, and by current be converted to shown in arrow B laterally. Then, water is along arrow C, D, ESequential flowing, thereby can bring into play well in fact in the same manner filter material 32 with the respective embodiments described aboveFiltration. In addition, the hydraulic pressure of the water that holding plate 40 flows into along arrow A direction by reception, therebySupport reliably with the state that joins filter material 32 upper surfaces to. Thus, can bring into play as holding plate40 function. In addition, can not use the filter core member of supporting filter material 32 use etc., thereby can provide the simplestSingle cheap filter 39. Further, according to the kind of cloth etc., the coiling of some filter material 32 finishes endPortion likely can peel off. In this situation, for example, can enter by rope class etc. at the Zhou Fangxiang of filter material 32Row is tied up. As rope class, for example, there are cotton thread or elastic tape etc.

On the other hand, Figure 11 is the figure that is equivalent to Fig. 1 (b) that represents other different embodiments. ShouldFilter 42 possesses the outstanding outstanding end difference of ring-type that is arranged on the bottom peripheral part in shell main body 1919c. This outstanding end difference 19c is for keeping being loaded the bottom of the filter material 32 being housed in shell main body 19Outside portion. In addition, the holding plate 34 that covers filter material 32 tops from top is in fact with shown in Fig. 8The holding plate of the second embodiment is identical.

According to this structure, when filter material 32 is about to move, can stop this to move by outstanding end difference 19c.Further, although omitted the arrow A that represents current to arrow E in Figure 11, this filter 42 alsoCan performance bring into play in the same manner good filtering function with the respective embodiments described above. In addition, also can use figureHolding plate 40 shown in 10 replaces holding plate 34. , the form of holding plate 34 is also widenable to otherVarious forms. In addition, in the filter 39 shown in Figure 10, can replace with holding plate 34,Holding plate 40.

(the 3rd embodiment)

Directly over this feed water inlet 108 almost protrudes from linearly. For switching from outside waterThe supply of the water in source and the tap of cut-out 109 and flexual water supply hose 110 install 102 after filtrationBe communicated to this feed water inlet 108 watertight. This filter 102 is for the impurity of filtered water, to this withRear detailed description. This filter 102 is arranged on from external water source to feed water inlet 108(washing machine 101) instituteIn the water supply path of meaning. Further, can adopt pipe clamp at the connecting portion of water supply hose 110 as required111. This clip 111 prevents from the member that flexible pipe comes off from closely linking water supply hose 110 as being used for.

Then, Figure 14 to Figure 18 represents the concrete structure of filter 102. At this, with reference to Figure 16'sThe cutaway view of longitudinal section, Figure 17 and the exploded perspective view of Figure 18, describe this concrete structure.Filter 102 is formed as the cylindrical vessel shape of hollow on the whole, and it possesses filter housing 112 and filter core listUnit 113. Filter housing 112 is in its one end, center upper portion portion has inflow entrance 116, at the other end, underThe central portion of portion (bottom) has flow export 117. Filter core unit 113 is housed in this filter housing 112.

Filter housing 112 is by the upper table that has the shell main body 114 of bottom tube-like and watertight and cover this shell main body 14The cover 115 of face forms. These shell main bodys 114 and cover 115 are all ester mouldings. In this case, at leastShell main body 114 for example, by transparent resin material (acrylonitrile-styrene resin, polycarbonate resin, thirdOlefin(e) acid resin) form, thus can have an X-rayed inside. Flow export 117 is in the bottom (bottom) of shell main body 114With cylindric outstanding downwards. Inflow entrance 116 is given prominence to upward with cylindric above cover 115.

In the open end of shell main body 114Side, is formed with the internal thread part 114a corresponding with external thread part 115a. By the sealing shown in Figure 16Circle 118 links these threaded portions 115a, 114a, thereby forms filter housing 112. In this filter housing 112, shellMain body 114 and cover 115 when watertight combination, are formed as removable structure each other. Further, as figureShown in 16, on cover 115 inflow entrance 116, be connected with the water supply hose 110 representing with double dot dash line, underOn the flow export 117 of portion by the chimeric feed water inlet 108 representing with double dot dash line that is connected with.

On the other hand, in the bottom center of shell main body 114, be formed with the row that diameter is less than flow export 117Water hole 119. The cylindrical wall portion 120 of toroidal protrudes near medial surface osculum 119. As Figure 17Shown in Figure 18, be provided with the slot part 121 forming by a part for cutting cylindrical wall portion 120. ShouldSlot part 121 communicates with osculum 119 and flow export 117. Further, the flow export 117 of outer bottom is by closeBe fitted to the feed water inlet 108 of washing machine 101 seal 122 watertights. Thus, as shown in figure 16, filter housing112 are kept with substantially vertical upright state. Like this, the diameter of osculum 119 is less than flow export 117So that sealing ring 122 to be installed. This osculum 119 as the outlet for draining of filter housing 112, is being brought into play in factCommon effect.

Next, with reference to Figure 14, Figure 15, to being housed in the filter core unit in the filter housing 112 of said structure113 structure describes. Figure 14 is the stereogram of filter core unit 113, and Figure 15 (a) is filter core unit113 side view, Figure 15 (b) expression is cut off filter core unit 113 along the A-A line in Figure 15 (a)Cutaway view. Figure 19 represents the use state of filter 102. Conventionally, specifically as shown in figure 16,Filter 102 is positioned at top, flow export 117 and is positioned at the sensing above-below direction of bottom at inflow entrance 116State under use. Then, as shown in figure 16, filter core unit 113 is to be erected at the shape in filter housing 112State is accommodated. Filter core unit 113 is at least in the internal face of filter housing 112, i.e. upper wall surface 112a and peripheral wall surfacesBetween 112b, gapped state is accommodated. The passage passing through for current while water supply as aftermentioned in this gap.

More particularly, filter core unit 113 is made up of holding plate 123 and filter core member 124 cylindraceous,Described holding plate 123 is for example formed as by integrally formed discoid of acrylic resin, described filter core member124 extend downwards in the rear side of this holding plate 123. Like this, in filter core unit 113, holding plate123 and inflow entrance 116 between gapped and mutually opposed. In addition, the opening of filter core member 124 lower ends is torn openDress is entrenched in the outside of cylindrical wall portion 120 freely. As shown in figure 16, filter core member 113 is thisUnder bearing state, be accommodated in filter housing 112. But, make filter 102 establish in spendableConfiguration state, need to take off under cover 115 state, filter material 128 is reeled be installed on filter core member 124 itAfter, accommodate this filter core unit 113, thereby form installment state, this is described in detail subsequently.

As shown in figure 14, the holding plate 123 of formation filter core unit 113 possesses integratedly flat conditionThe central part on surface is multiple (for example 4) jut 125 of radiated entends. This jut 125 removesBe formed as radially with the position beyond the opposed centre of opening of inflow entrance 116, and be formed asProtrude separately vertical tabular shape. Further, this radial jut 125 receives from inflow entrance 116The water flowing into, evenly spreads to peripheral direction by these current, afterwards its effect is elaborated. CauseThis, jut 125 is not limited to tabular, can be for example chevron cross section, or can not be also continuousThe shape of projection. , can carry out various distortion to jut 125.

On the other hand, filter core member 124, on the almost whole surface of perisporium cylindraceous, for example hasCancellate multiple reach through hole 124a. Thus, filter core member 124 is formed as the good structure of water flowing.The shape of each reach through hole 124a is set to be easy to make holding plate 123 and the integrally formed shape of filter core member 124Shape, thereby need not be set to same shape. In addition, as shown in figure 16, as filter cylindraceousThe shape of core component 124, is designed to its diameter dimension, the dismantled and assembled shell main body 114 that is entrenched in freelyThe cylindrical wall portion 120 of bottom on diameter dimension, filter material 128 is being arranged on and is having reach through hole simultaneouslyUnder the state of the perisporium of 124a, and between the medial surface of shell main body 114, there is the diameter dimension of specified gap.

As shown in figure 16, be contained in the filter core unit 113 in filter 102, at filter 102Internal face, i.e. upper wall surface 112a and peripheral wall surfaces 112b between the gap that forms, as in figure to arrow sidePlay a role to mobile water stream channel. Water is by being installed on filter material 128 whole of filter core member 124Surface, through the feed water inlet 108 of washing machine 101, is not supplied to figure from reach through hole 124a and flow export 117In the sink showing.

As shown in Figure 14, Figure 15, on the perisporium of filter core member 124, be further formed with a slit 126.This slit 126 is formed on the whole of direction to cylindric extension (following, to be called " length direction " of cylinder)On individual length range. For example linearly opening of this slit-shaped 126. In addition, right across this slit 126Gap size between the perisporium both ends of putting is that A/F is formed as, and can clamp filter material 128 endsNarrow and small width dimensions, describes in detail subsequently to this. And, as shown in Figure 15 (a) and (b), comprise that this is narrowThe upper end of the perisporium of seam 126 is formed with the almost grooving portion 127 of half cycle. That is to say, form grooving portion127 part is formed with gap, by this gap, and 123 points of a part for filter core member 124 and holding platesFrom. In addition, by this gap, become easily elasticity across the opposed all end wall of slit 126The shape of distortion. Further, many slits 126 also can be set.

Then, with reference to Figure 12 and Figure 13, the material to above-mentioned filter material 128 and be installed on filter core listThe seating means of unit 113 etc. describes. First, as the material of filter material 128, for example, utilize nothingSpin the material that cloth is thinly sliced. But as the material of filter material 128, it is not limited only to this, also canUse can be wrapped in the soft cloth of filter core member 124 periphery walls. Therefore, friperie and the clothes of not wantingMaterials etc. also can utilize. In addition, as the size of filter material 128, nonwoven is cut into the thin of rectangleSheet, make its length dimension be greater than filter core member 124 perisporiums whole circumference size (circumferencial directionSize), width dimensions is than large several millimeters of the size of the length direction cylindraceous of filter core member 124 (mm).

Then, as shown in Figure 12 (a), in the time being installed on filter core member 124, regulation shape will be cut intoLaminar filter material 128 is attached to the peripheral wall surfaces in its outside. Then, as shown in Figure 12 (b), with by this filterOne end of material 128 is pressed into the mode of slit 126 and inserts. Keep this state, by another of filter material 128Distolateral being wrapped on filter core member 124. Then, as shown in Figure 12 (c), at the other end of filter material 128When side arrives the position of slit 126, by this another distolateral insertion slit 126. In this case, due to filterIn core component 124, be that resin is made across the both ends of slit 126, thereby possess elastic force. In addition,On this basis, be provided with grooving portion 127 across the position, top at the both ends of slit 126. That is to say,Filter core member 124 is formed as the structure separating across gap between its part and holding plate 123. Thus,Both ends across slit 126 in filter core member 124 are more rich in elastic force, even if do not apply undue external forceAlso strain easily.

Therefore, pressing and making across the opposed both ends of slit or an end filter core member 124Its distortion, thus slit 126 expanded, in this state, can easily insert another of filter material 128Distolateral. Then, insert another of filter material 128 distolateral after, if except whereabouts filter core member 124Power (pressing force), filter core member 124 flexibly returns to original-shape, thereby in its A/F bulletThe both ends of property ground clamping filter material 128. That is to say, by across the opposed filter core member of slit 126124 perisporium both ends, top portion and the terminal part of the filter material 128 that flexibly clamping is reeled. Thus,As shown in Figure 12 (c), filter material 128 is mounted with the state of the peripheral wall surfaces that is close to filter core member 124.

Further, Figure 13 represents to watch from side below the state of the installment state that Figure 12 (c) illustrates. ,With the both ends that are close to the filter material 128 that the mode of periphery wall of filter core member 124 installs from slit 126Be inserted into inside, its insertion is equivalent to have more than the circumferencial direction size of the periphery wall of filter core member 124Part.

Like this, the filter core unit 113 that filter material 128 is installed is housed in filter housing 112, make its inThe spendable state that arranges, need to take off cover 115 by the filter core unit 113 that filter material 128 is installedUnder state, be housed in shell main body 114, and make the chimeric supporting in bottom of filter core cylindraceous unit 113In the outside of the cylindrical wall portion 120 of filter housing 112 inner bottom parts. Now, the filter material inserting from slit 126128 both ends abut to cylindrical wall portion 120, thereby likely cannot obtain appropriate chimerism.

But as shown in Figure 17 and Figure 18, a part for cylindrical wall portion 120, is provided with fluting stateSlot part 121. Thus, be entrenched in tubular by the position that makes slit 126 with the mode that this slot part 121 alignsWall portion 120, thus the both ends of filter material 128 can be stored in slot part 121. That is to say slot part121 played a role as 128 the keeping out of the way portion of both ends of filter material. Thus, can be successfully with reliable and stableChimerism filter core unit 113 is set. In addition, the width dimensions of filter material 128 is than filter core structure cylindraceousLarge several millimeters of the size of the length direction of part 124. Therefore, can be easily to cover filter core member 124The mode on the whole surface of perisporium is wound around filter material 128. But, the bottom of the filter material 128 after installation a littleOutstanding. But, can by the flexibility of filter material 128 itself or after arranging filter core unit 113Total weight be applied to the lower end of filter material 128, thereby under shakedown, filter material 128 is set toThe bottom (cylindrical wall portion 120) of shell main body 114.

Afterwards, cover 115 is arranged in shell main body 114. Then, as shown in figure 19, soft by supplying waterManage 110 grades outside watering and washing machine 101 are coupled together, can supply to washing machine thereby set forThe state of water, and then can be by the operation water supply start action of the tap 109 of fetching boiling water. Further, aboutThis washing machine 101, also has such washing machine, and the downstream of its feed water inlet 108 possesses not shown exampleAs the feed water valve of electromagnetic type, can automatically start washing operation according to the action of supplying water. In this case, canTo make in advance tap 109 in open mode. Then, control electricity by the control device of washing machineThe switching of magnetic-type feed water valve, thus the water supply action by filter 102 can be carried out.

Then, the effect of the filter 102 using in the washing machine 101 of above-mentioned formation is described.

From the running water of external water source by the tap 109 of fetching boiling water, through water supply hose 110, filter102, feed water inlet 108 is supplied to not shown sink. Then, when supplied with regulation water in sinkAfter the water of amount, by closed tap 109, can stop the action of supplying water. Afterwards, user's operating operation facePlate 107, sets the washing working procedure of expectation etc., and brings into operation. Thus, carry out general crowd institute weekThe washing operation of knowing.

At this, the effect of the filter 102 in above-mentioned water supply action is elaborated. As above instituteState, filter 102 is arranged in the water supply path of washing machine 101. Therefore, be accompanied by the fire hose109 open, running water arrives filter 102. Figure 16 represents this filter 102 to arrangeFor spendable state, describe with reference to Figure 16, water is from the inflow entrance 116 on the top of filter 112Flow in this filter housing 112, and the direction diffluence representing to arrow in figure.

Form the holding plate 123 that is arranged on the filter core unit 113 in filter housing 112, be configured to towards inflow entrance116 state. Therefore the water, flowing into from inflow entrance 116 is to impact the substantial middle position of holding plate 123Surperficial mode flow into. At this moment, produce to pressing the mobile pressure of direction at holding plate 123. This pressureMasterpiece is used in filter core member 124 and is embedded in the direction of cylindrical wall portion 120. Therefore, filter core member 113 energyEnough states arranging of erectting that stably maintains. Then, the flow direction of the water of inflow is converted to right angle orientation, toThe peripheral direction diffluence of holding plate 123. In this case, on the surface of holding plate 123, be provided with therefromMultiple (for example 4) radial jut 125 that heart side direction outer circumferential side extends. By these jutsThe dirty water to peripheral direction of 125 guiding, under the homodisperse rectified action of circumferencial direction, swimminglyFlow and do not produce the sinuous flows such as useless eddy current.

Then, above filter core unit 113 and side, current through as passage with filter housing 112Gap between internal face, flows downwards along the medial surface of filter housing 112 from the outer circumference end of holding plate 123Under. This water that flows to below immerses from the below of filter material 128 gradually. In this case, according to forming filterNumber of the material kinds such as the cloth of material 128 and output etc., the water level in filter housing 112 rises gradually.Then, in filter housing 112, become very soon full water state. Further, according to the kind of the material of formation filter material 128Class, this water flowing resistance can change.

Consequently, tap water hydraulic is applied in filter housing 112, and water circulates in rapidly water through filter material128 is all. Particularly, water is from the reach through hole of the inner filter core member 124 of the outside process of filter material 128124a flows out to central side. Then, osculum 119 and the flow export 117 of water process filter housing 112 bottoms,Be supplied to the feed water inlet 108 of the washing machine 101 shown in Figure 19, in not shown sink, supply water. ThisSample, all water of supplying with from tap 109 are all by filter material 128 and be filtered. Thus, can effectively removeRemove iron rust and the small impurity etc. of in running water, sneaking into, the clean water that has filtered impurity is supplied toWashing machine 101.

Then,, after supplying water to sink, closed tap 109, stops supplying water. After water supply stops,Having water residual in the water supply path of filter 102 slowly flows out to sink. At this, filter is describedThe processing of residual water in device 102. As shown in Figure 16, water mainly passes through filter material 128 and filter core member 124Reach through hole 124a flow out from osculum 119. But, once that the water level in filter 112 drops to is lowIn the low water level of the reach through hole 124a of foot, the inner peripheral portion of filter core member 124 bottoms and position are in the innerThe cylindrical wall portion 120 of portion likely can stop water to circulate to osculum 119.

But filter 102 forms in the total length of the length direction of filter core member 124 cylindraceousThere is slit 126. And this slit 126 is entrenched in relative with the slot part 121 that is formed on cylindrical wall portion 120The position of answering. As shown in figure 17, according to this structure, can be by the filter material inserting from slit 126 128Both ends are stored in slot part 121. The filter material 128 that, slot part 121 conducts are inserted from slit 126The keeping out of the way portion of both ends and playing a role. In addition, slit 126 forms through slot part 112 and is communicated to osculum119 passage. Therefore,, even if become low water level in filter housing, water also can be through this passage in Figure 17Arrow indicated direction flows and gets rid of from flow export 117.

Like this, slit 126 and slot part 121 form the structure of effectively processing filter material 128 both ends. Meanwhile,Slit 126 and slot part 121 also can effectively be brought into play the function of processing residual water. Further, although filter material 128Be clamped in slit 126, but can be according to the water flowing performance draining at leisure of this filter material 128,Or can be from drainings at leisure such as small gaps.

But, being accompanied by use, the mesh that the impurityes such as the iron rust of being caught by filter material 128 cause stops up shapeState develops gradually. Because filter housing 112 is transparent resins, thereby can be by from outside with the naked eyeObserve the pollution condition of filter material 128, easily discover this mesh blockage. Therefore, can hold at any timeChange places and distinguish the mesh blocked state of filter material 128, can not miss the impurity of removing filter material 128 period,Or the replacing period of novel filter material. Thus, always can maintain good strainability.

And user can easily carry out the disassembly and assembly operation of filter 102. This dismounting is doneIndustry describes, and passes through the chimeric filter connecting 102 energy in water supply hose 110 water supply paths such as gradeEnough easily take off. Then, in the filter 102 that this takes off, dismounting filter housing 112. , filter housing112 are screwed to this main body water tank 114 by shell main body 114 and by the 114a of internal and external threads portion, 115aCover 115 forms. Therefore, can, only according to the simple operation of rotation operation cover 115, separate these main bodysWater tank 114 and cover 115. Thus, can, from the upper surface open of the shell main body 114 opened, take out bagContaining the filter core unit 113 of filter material 128. In this case, the bottom dismounting of filter core member 124 freelyBe entrenched in the cylindrical wall portion 120 of shell main body 114, filter core member 124 is only supported with the state of erectting.Therefore, do not need special operation, can take out filter core unit 113.

Then, from the filter core unit 113 taking out, take off filter material 128. In this case, filter material 128 bulletsProperty ground is clamped in filter core member 124 across between the perisporium both ends of slit 126. Therefore, for example, from filterOn material 128, press the side in these both ends, this part generation strain, the opening of slit 126 is wideDegree also expands. Therefore, can on one side from slit 126, pull out filter material 128 by one side pressing operationEnd, easily frees the end of filter material 128. In addition, by freeing from clamp positionThe one side tractive lightly of filter material 128 out, can take off the opposite side of remaining filter material 128.

For example can be by washing, the impurity that the filter material taking off 128 is caught is removed. Or, willFilter material 128 is replaced by new filter material. Like this, again, filter material 128 is arranged on to the filter of filter core unit 113On core component 124. Further, the erection sequence of filter material 128 as shown in figure 12. In addition, be assembled into filtrationAfter device 102, the reverse order during according to above-mentioned dismounting is arranged on this filter 102 for water routeIn footpath, also can easily carry out fitting operation.

As described above, according to the 3rd enforcement side of filter 102 that is applicable to washing machine 101Formula, can expect to obtain following effect.

In 101 water supply path from external water source to washing machine, filter 102 is set, thereby can carriesFor the water having filtered after the purification of the impurityes such as iron rust. Thus, can eliminate the danger of iron rust to washings etc.Evil. In addition, can be easily from filter 102, installation or removal are used for catching iron rust etc. and mixThe filter material 128 of thing. Particularly, as the installation of the filter material 128 illustrating according to Figure 12 (a) and (b), (c)Shown in order, laminar filter material 128 can be wound on to the cylindric filter core member 124 of resin manufacturePerisporium on, the slit that perisporium is provided with is inserted in the both ends of the top portion of this filter material 128 and terminal partIn 126, thereby flexibly grip.

This means that grip are being arranged on filter material 128 on filter core member 124, or from filter core structureWhen part 124 takes off filter material 128, do not need special fixture, can be undertaken by simple handwork.Result is, can change simply filter material 128, easily maintains filter 128, maintains the filtration of expectionPerformance. In addition because filter housing 112 is made up of transparent resin, thereby can with the naked eye see from outside,Examine filter material 128, easily judge this mesh blocked state according to pollution condition etc. Therefore, can not miss clearlyWash or change the period of filter material 128, very easy to use.

And, due to the top portion of filter material 128 and terminal part harvesting are clamped in slit 126, therebyCan clamp reliably the both ends of the filter material 128 that is easy to peel off. In addition, can be by a filter material 128The roughly whole peripheral wall surfaces that is wound on filter core member 124 with thickness equably, obtains uniform water flowing.Thus, can, at the almost whole surface performance filtering function of filter material 128, can expect the better mistake of efficiencyFilter performance. And, as the material of filter material 128, can use according to the size of reeling and thinly slice shapeThe cloth such as nonwoven, friperie. Therefore, in general family, easily prepare the material of filter material 128, valencyLattice are cheap and practical.

In addition, in order flexibly to clamp top portion and the terminal part of filter material 128, holding plate 123 and filter coreMember 124 combines in one piece. But, the inner peripheral portion that comprises slit 126 and holding plate123 separate, and that is to say, to form the mode in gap, grooving portion 127 are set. Thus, across slit 126Two inner peripheral portion become and be easy to deflection, even if for example consider the intensity of resinous filter core member 124And increase thickness does not need large pressing force can make its strain yet, can hold according to handworkChange places and clamp filter material 128. But holding plate 123 and filter core member 124 can not be integrally formed, alsoCan be for example by the structure of the strong bonded such as binding agent. In this case, replace grooving portion 127, doFor the gapped structure of position tool in this grooving portion 127, integratedly in conjunction with holding plate 123 and filter core structurePart 124, that is to say, holding plate 123 is separated at gap portion with a part for filter core member 124Combination integratedly under state.

And then, in filter housing 112, accommodate and arrange the structure of the filter core unit 113 that filter material 128 has been installedAs follows: to make cylindrical wall portion 120 protrude near the inner bottom part flow export 117 of filter housing 112, by filter coreOne end of member 124, lower ending opening is entrenched in this cylindrical wall portion 120, thereby with dismounting freely and stableState support filter core unit 113. But, if do not taken measures, cylindrical wall portion 120 can with from filter core structureThe end phase mutual interference of the filter material 128 that the slit 126 of part 124 inserts. That is to say cylindrical wall portion 120Mutually conflict and produce obstruction with the end of the filter material 128 inserting from slit 126, making filter core member 124Cannot be entrenched in reliably in cylindrical wall portion 120.

Thus, slot part 121 is set in cylindrical wall portion 120. Osculum is led in one end of this slot part 121119 and flow export 117, the other end is corresponding with the slit 126 of filter core member 124. Therefore, can by fromThe end of the filter material 128 that slit 126 inserts is stored in slot part 121. Thus, filter core member 124 reliablyChimeric and be stably supported with cylindrical wall portion 120. And then, slit 126, slot part 121 and flow export117 form continuous passage. Therefore, even if the water level in filter housing 112 becomes lower than cylindrical wall portion 120,Also can carry out draining, can process (eliminating) residual water.

(the 4th embodiment)

Figure 20 represents the 4th embodiment. Further, Figure 20 (a) is the figure that is equivalent to Figure 14, Figure 20(b) be the ground plan of filter core unit. In the present embodiment, form the filter core member of filter core unit 129130 shape has part difference. Other key elements are identical with the 3rd embodiment.

Below, its difference is described. That is, as shown in figure 20, in filter core member 130 across slit 131Perisporium both ends be formed as mutually not opposed. , across the perisporium both ends of slit 131 in circumference sideTo not opposed mutually. For example, as shown in Figure 14 and Figure 15 (b) etc., in the 3rd embodiment across slit126 perisporium both ends, across slit 126 arranged opposite in fact of linearity. On the contrary, this enforcement sideIn formula, depart from diametrically across the both ends of slit 131, in non-opposed position. Further, itsHis key element, i.e. cancellate reach through hole 130a and form the grooving portion 127 in gap between holding plate 123Deng, be identical shape with the 3rd embodiment.

According to this structure, stagger across the position at the both ends of slit 131, thereby in advance in depth direction(radially) form peristome. Then, even if this peristome is small opening, across slit 131In perisporium both ends, for example from outside by very little power along the side representing by hollow arrow Figure 20 (b)To the end of pressing inclined to one side inner side, just can easily increase the deflection (distortion of depth direction (radially)Amount). Then, by the large peristome of deflection quantitative change, the end that can insert not shown filter material, easilyCarry out the insertion operation of filter material.

Further, after slit 131 inserts the end of filter material, if eliminate pressing force, the perisporium of distortionEnd return to original position, thus, can flexibly clamp the end of filter material. In addition, about itHis structure, can expect to obtain the effect same with the 3rd embodiment.

(the 5th embodiment)

Figure 21 is the figure that is equivalent to Figure 14 that represents the 5th embodiment. In this case, form filter coreThe slit 134 forming on the filter core member 133 of unit 132 with and the shape of periphery have part difference.Other key elements are identical with the 3rd embodiment. Further, filter core member 133 has reach through hole 133a.

, be formed as concaveconvex shape across the perisporium both ends of the opposed filter core member 133 of slit 134.Then, recess and protuberance relative configuration in intermeshing direction each other. Result is, slit 134Be formed as concaveconvex shape.

According to this structure, insert the not shown filter material end of slit 134, be formed concaveconvex shapePerisporium both ends elastic bearing. Therefore, with the clamping part based on straight slit 126 of the 3rd embodimentPosition is compared, and by the clamping part of concaveconvex shape, has prevented filter material slip, and then can fix reliably.Further, as the shape of this concaveconvex shape, be not limited to the wave-like shown in present embodiment, canVarious concaveconvex shapes such as such as zigzag or triangle etc.

Figure 22 be represent relative with above-mentioned the 3rd embodiment, the 4th embodiment and the 5th embodimentThe figure variation of answering, that be equivalent to Figure 14. Below, in the most similar the 3rd embodiment of contrast, illustrateThe structure of filter core unit 113 describe.

The basic structure of the filter core unit 113 of this variation is identical with the 3rd embodiment, thereby possesses altogetherSame filter core member 124. But, give prominence to foreign side multiple are set on the perisporium of this filter core member 124Projection 135 this point differences.

According to this structure, when not shown filter material 128 is wound up into the perisporium of filter core member 124, andAfter coiling is fixing, the resistance that projection 135 stops filter material 128 to slide effectively. Thus, can strengthenOperability when coiling filter material, or filter material can be maintained to initial reeling condition, thus can the phaseTreat stable strainability. Further, if projection 135 is arranged on to perisporium upper of filter core member 124Isoperimetric end, bottom, may produce gap current are immersed. Therefore, projection 135 is preferably arranged onThe above-below direction of perisporium by ectocentral position.
