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.The water inlet side of this feed water valve is connected with outside water source (for example running water).Generally, the water inlet side of this feed water valve is provided with metal filter.This filter is formed as for example structure of the mesh specification of per inch 60 meshes, width of mesh 0.24mm left and right, to prevent the immersion of impurity.But, sometimes at water source, be also mixed with impurity in running water.For example, while thering is the supply equipment such as running water pipe and aqua storage tank, follow it aging, also can produce the iron rust that is called red rust.If sneaked into the iron rust of such generation, running water can become muddy 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 bring out the generation of washing iron rust in cell body or water flowing path.Further, if iron rust is stacked into the inside of feed water valve, also may cause fault.In addition, iron rust has all size, for example, count the small iron rust in μ m left and right and sometimes also can sneak in a large number in running water.The general filter that above-mentioned feed water valve has, cannot filter this 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 to supply water with many as the situation of washings.In this case, use the water capacity that contains the impurityes such as iron rust easily to cause pollution or the variable color of washings, and then easily bring out the generation of washing iron rust in cell body or water flowing path.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, survey the filter with filter material is set in the upstream of the feed water valve of washing machine, this filter material is made up of lamellar material.
But the filter material filtering as general water flowing, is to use a lamellar material, the i.e. lamellar material of individual layer substantially.Like this, although it is good to simplify fixing means and the water flowing of filter material, 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 subject to materials limitations and becomes dull.That is to say, mesh changes according to used material, causes the functional lability of filter, and even, the mesh size of material may cause mesh blocked state in advance.
On the other hand, if by by supply-water pump from the water of the storage water source supplies such as the water for bathing of external water source as washings, can using water wisely, and can expect the good clean result of being brought by warm water for bathing.Therefore, this washing machine of supply-water pump that utilizes is also extensively universal.Then, as disclosed in patent documentation 2, as the filter of water for bathing, occur for example utilizing whirlwind separator etc. to remove the structure of impurity.
In addition, also can consider following structure: while using supply-water pump, possess the water sucking mouth with filter at the leading section of water supply path, and this water sucking mouth is put in bathtub.But, stopping up for fear of there is in advance mesh, the filter of this water sucking mouth generally does the structure that ramify is sparse.Therefore, cannot bring into play sufficient filtering function.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 the major reason that causes washings jaundice or undesirable stink, therefore, use water for bathing to need further to improve reliability as washings.
In addition, in this filter, when the impurityes such as the iron rust that laminar filter material is in use caught cause mesh blocked state, its water flowing significantly reduces than usual.Therefore, in order to make the filtering function of filter performance expection, the effect of catching of impurity become insufficient before, the impurity that need to carry out by for example method for washing, filter material being caught is removed, or is replaced by the disposal such as new filter material.Therefore, need one to use structure more easily, the easy dismounting of such as filter material is in filter and can install reliably and keep structure of filter material etc.

Fig. 2 represents the stereoscopic figure of the use state that uses filter in washing machine, and the overall structure of the washing machine representing in this accompanying drawing etc. is summarized.The main body 2 that forms washing machine 1 gabarit forms by the outer container 3 of approximate rectangular case shape and 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 opening and closing the input port of not shown washings.Top cover 4 can drop into and take out washings to the not shown cell body of inside by this input port.And then, at the rear portion of top cover 4, be provided with highlightedly upward the feed water inlet 7 for supplying water to cell body.Detailed content about this feed water inlet 7 describes in detail subsequently.
As general structure, cell body by stirring body, rotatable cellular swivelling chute and capable of storing water be configured in swivelling chute tank around and form.The washing machine 1 with this cell body substantially all possesses the function of each processes such as automatically performing washing stroke, rinsing stroke, dehydration stroke.To be the water of hose 8 in order supplying with from external water source, on feed water inlet 7, to 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 on from external water source to feed water inlet in 7 water supply path.Further, hose 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 represents the 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 formed with external thread part 7a, metal filter 12 is installed in the interior perimembranous of feed water inlet 7.This filter 12 immerses washing machine 1 inside for preventing impurity.Further, flexible annular seal ring 13 is installed on the base portion of the peripheral part of feed water inlet 7.Sealing circle 13 leaks for preventing the linking part between filter described later 11.This feed water inlet 7 is directly attached to the water inlet side of the not shown feed water valve that is arranged on top cover 4 rear side.Or this feed water inlet 7 is integrally formed in the water inlet side of feed water valve.The feed water valve being communicated with feed water inlet 7 like this can supply water by the private water supply path in cell body from this delivery port side.
Then, filter 11 is attached between feed water inlet 7 and water supply hose 10.This filter 11 possesses: filter housing 14, and it is large diameter cylindric that face shaping is; Inflow entrance 15, is diameter on the top of filter housing 14 and is less than the cylindric of filter housing 14; Flow export 16, is diameter in the bottom of filter housing 14 and is less than the cylindric of filter housing 14.In the lower side of this filter 11, flow export 16 is connected with feed water inlet 7.On the tubular inner peripheral surface of flow export 16, be formed with internal thread part 16a, the external thread part 7a of feed water inlet 7 screws in this internal thread part 16a.Thus, in the lower side of filter 11, flow export 16 and feed water inlet 7 are able to combination by these threaded portions 7a, 16a.Now, because sealing ring 13 is compressed, flow export 16 and feed water inlet form watertight and link.
On the other hand, in the upper side of filter 11, on the outer peripheral face of inflow entrance 15, be formed with external thread part 15a.And the nut member 17 that is arranged on water supply hose 10 bottoms possesses and is doublely the internal thread part 17a of cylindrical-opening portion and has integratedly the 17b of rotatable handle portion of this internal thread part 17a.The external thread part 15a on filter 11 tops screws in this internal thread part 17a.In this case, linking filter 11 under the state of washing machine 1, the nut member 17 that flexual water supply hose is possessed is aimed at the top position of external thread part 15a, and then in conjunction with external thread part 15a and internal thread part 17a.In this case, on the base portion due to the peripheral part of inflow entrance 15, install to have flexible annular seal ring 18 compressed, thereby inflow entrance 15 links with watertight state with nut member 17.Therefore, filter 11 has 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, describe according to the exploded perspective view of the filter 11 shown in profilograph and the Fig. 4 of the filter 11 shown in Fig. 1.The first half in the filter 11 that Fig. 1 (a) represents to be installed on washing machine 1 state before use, 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 the shell main body 19 of bottom tube-like and cylindrical vessel shape and forming to cover the cover 20 that the mode of its upper surface arranges.Further, at least shell main body 19 is to be formed by transparent resin material, makes to have an X-rayed inside.As transparent resin material, for example, 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 16 outstanding from the bottom of shell main body 19.In addition, at bottom center and the private side of flow export 16 in opposition side of shell main body 19, be provided with integratedly the outstanding for example cylindrical wall cylindraceous portion 21 from the bottom of shell main body 19.This cylindrical wall portion 21 is outstanding upward in Fig. 1, is formed on flow export 16 in concentric position.Because the diameter of this cylindrical wall portion 21 is less than flow export 16, be formed with the end difference extending to radially inner side in the boundary portion of cylindrical wall portion 21 and flow export 16.There is flexible sealing ring 22a and be arranged on this end difference.Thus, when the flow export 16 shown in Fig. 3 is attached to feed water inlet 7, sealing ring 22a is compressed between the leading section of this feed water inlet 7 and end difference.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.At cover 20 central portion, form top in digraph 1, the i.e. outstanding inflow entrance 15 to outside.In addition, on the peripheral end face of cover 20, formed external thread part 20a, for screwing in the internal thread part 19a of shell main body 19.Link these internal thread parts 19a and external thread part 20a across sealing ring 22, shell main body 19 and cover 20 can be carried out to watertight link thus, 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, in the filter housing 14 forming like this, contain filter core member 23, filter material 24 and holding plate 25.Filter core member 23 is to be erected at the cylindrical structural member that the state of the bottom center of shell main body 19 is supported.Filter material 24 remains on the outside of filter core 23, for removing the impurity that is included in water.Holding plate 25 is disc-shaped components that the mode to cover these filter core members 23 and filter material upper surface from top is installed.Further, the top of filter core member 23 and filter material 24 not only refer to these filter core members 23 and filter material 24 directly over, as long as at least higher than the position of filter core 23 and filter material 24, also comprise 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, is formed with and is for example cancellate multiple reach through hole 23a.Filter core member 23 forms the good structure of water flowing by multiple reach through hole 23a.The filter core member 23 of this drum is formed as diameter than larger in the outstanding cylindrical wall portion 21 of the bottom center of shell main body 19.Thereby filter core member 23 is supported by cylindrical wall portion 21 with upright state by being fitted to cylindrical wall portion 21., the effect of so-called align member, as dismantled and assembled at assigned position and with the member of upright state supporting filter core member 23, is played by cylindrical wall portion 21.
Filter material 24 can be the cloth that can overlappingly be wound on filter core member 23 peripheral parts, and such cloth for example comprises all materials such as friperie, the shirt of not wanting or underwear, stocking, towel.By for example thinner cloth cut into figure in height dimension, i.e. the length dimension size on an equal basis of filter core member 23, and the cloth multiple-layer overlapped of cutting is wound on filter core member 23, thereby forms filter material 24.Form filter material 24 cloth the number of plies, the overlapping coiling number of times of cloth can be for example 9 layers of left and right.
About this filter material 24, describe with further reference to Fig. 5 (a) and (b) of the overlapping coiling order that shows filter material.That is, as shown in Fig. 5 (a), according to the length dimension of filter core member 23, in other words along the 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 the top side of this cloth, rotates and be wound around towards the direction of arrow in figure, thereby wrap into the outer peripheral face of this filter core member 23 with cloth.Then,, on the cloth of revolution winded filtering core member 23, further which floor cloth of overlapping coiling is take package as multilayer shape.Fig. 5 (b) represents to have reeled the state of specific length cloth.Because filter material 24 is that overlapping coiling cloth forms, thereby incrust, consequently, filter material 24 can remain on cloth as the filter core member 23 of core around using the state of multilayer package.So carry out in the situation of overlapping coiling of cloth, be preferably overlapping coiling is carried out in upper end and the bottom of the end face alignment filter core member 23 of cloth, thereby 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 member 23 of the state of overlapping multilayer-wound filter material 24, be housed in and take off cover 20 to open shell main body 19 inside of upper surface.Be specially, the bottom of the filter core member 23 that forms 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 of cylindrical wall portion 21 is designed to, 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 is to guarantee to have between the outer peripheral face of cylindric filter material 24 and the inner peripheral surface of shell main body 19 size of sufficient room.In addition, between the periphery wall of cylindrical wall portion 21 and the inner peripheral surface of the lower surface of filter core member 23, produce gap S1.But the weight of the whole filter material 24 by comprising filter core member 23, is close on the inner bottom surface of shell main body 19 lower surface of filter core member 23, thus, gap S1 can not arrive by the bottom of filter core member 23 outside of filter core member 23 continuously.
Like this, the structure being formed by filter material 24 and filter core member 23 is housed in shell main body 19.Then,, under this state, holding plate 25 is arranged on the structure being formed by filter material 24 and filter core member 23.Herein, the structure of this holding plate 25 is described.The basic structure of this holding plate 25 is to possess integratedly main part 26 and supporting teat 27.In main part 26 surfaces, upper surface is smooth, is formed as on the whole discoid.Supporting teat 27 is formed on the central portion of main part 26 rear side, is circular.Further, supporting teat 27 can be for example cylindric, can be also cylindric.Same with the chimerism that is formed with gap S1 between bottom at shell main body 19 bottoms, cylindrical wall portion 21 and filter core member 23, between the inner peripheral surface of the upper end of supporting teat 27 and filter core member 23, be formed with some gap 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 end of filter core member 23, i.e. upper end.Abut at the back side of holding plate 25 under the normal mounting state of filter core member 23 upper ends, 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 multiple juts 28.Horizontal surface that these juts 28 have at the main part 26 of holding plate 25, i.e. upper surface, be radiated entends from the central part of main part 26 respectively.Jut 28 except with the opposed centre of opening of cover 20 inflow entrance 15 position be formed as radial and be formed as respectively tabular outstanding shape.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 are elaborated.Therefore, jut 28 is not limited only to tabular, can be the cross section of for example chevron, or also can not be the shape of continuous projection., jut 28 can carry out various distortion.
After the holding plate 25 of said structure being installed on filter core member 23 and being housed in shell main body 19, at the upper surface open mounting cup 20 of shell main body 19.Be specially, between shell main body 19 and cover 20, arrange under the state of sealing ring 22, in conjunction with external thread part 20a and internal thread part 19a.Thus, formed the filter housing 14 that links the hollow container shaped of shell main body 19 and cover 20 with watertight state.Form thus the inner filter 11 that possesses the filtering function of filter material 24 grades.Then, as shown in Figure 2, by this filter 11 is as above installed, form the water supply path of the feed water inlet 7 from hose 8 to washing machine 1.
Further, in Fig. 2, by the key element that symbol 43 represents be, the pump that is directly attached to the supply-water pump 44 that is built in main body 2 is used feed water inlet.This pump is arranged on the position relative with feed water inlet 7 at the rear portion of top cover 4 with feed water inlet 43, this is described in detail subsequently.Another feed water inlet 7 is equivalent to the feed water inlet that so-called running water pipe uses, 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 hose 8 at water source, operating operation panel 5, sets the working procedure of expecting and brings into operation, and washing machine 1 is controlled by not shown control device, thus, automatically performs the operations such as such as washing stroke, rinsing stroke, dehydration stroke.At this, water supply action in washing stroke is described, washing machine 1 is opened not shown feed water valve, through water supply hose 10, filter 11 and be positioned at the feed water inlet 7 etc. of feed water valve upstream side, is supplied to the interior not shown cell body of main body 2 from the running water of hose 8.
Then, describe the effect of filter 11 in this water supply action in detail.First, describe with reference to the Fig. 1 (b) of use state that represents filter 11, from the flow through running water of water supply hose 10 of hose 8, flow in filter housing 14 from the inflow entrance 15 of filter 11.The water of this inflow have with Fig. 1 (b) in the inflow direction vertical plane shown in arrow A to surperficial holding plate 25 places received.Thus, the water of inflow 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 to tilt a little with the inflow direction of water.
Then, the surface of holding plate 25 possesses the radial jut 28 that You Cong center side direction outer circumferential side extends.Therefore,, by these juts 28, be subject to being distributed to equably the effect of circumferencial direction along the current radially shown in arrow B while flow.And holding plate 25 is installed in the mode that covers filter material 24 upper ends from top, and the pressure of the water being flowed into, thereby the effect of filter core member 23 and the filter material 24 of rear side is pressed in performance from top.Thus, holding plate 25 stops the end face side inflow of water from filter material 24 effectively.Further, even if in the situation that holding plate 25 tilts a little, the water being received by this holding plate also can disperse equably by the jut that is radiated entends.In addition, even if in the situation that holding plate tilts, because this holding plate has received the pressure of the water flowing into, thereby also can bring into play and press the filter core member of rear side and the effect of filter material from top.
Then,, towards the water of Radial Flow, as shown by arrow C, flow to below from the outer circumference end of holding plate 25 along the inner peripheral surface of filter housing 14.Then the water, flowing in filter housing 14 makes the below part of filter material 24 in impregnation 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, in water flows into filter housing 14, thereby this water is supplied to the white space of wherein filling up filter housing 14, thus, reaches rapidly or gradually full water state in filter housing 14.
Consequently, it is large that the tap water pressure in filter housing 14 becomes, and the water being under pressure as shown by arrow D, flows through from water through filter material 24.Be specially, water flows into central side from the periphery of filter material 24 through the reach through hole 23a of inner filter core member 23.Then, the water of inflow as shown by arrow E, through wall portion tubular 21 and the flow export 16 of filter housing 14 bottoms, is supplied to the feed water inlet 7 of washing machine 1.Then the water that, is supplied to feed water inlet 7 is supplied in cell body by not shown feed water valve.As mentioned above, the water of supplying with from hose 8 is all filtered when by filter material 24.Thus, can remove the impurity that cannot remove by the water inlet side of feed water valve, filter 12 that feed water inlet 7 has conventionally.In addition, even if the in the situation that of sneaking into small iron rust in running water, also can effectively remove this iron rust.Therefore, the clean water that has filtered impurity can be 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.In addition, the current that flow into towards arrow A are converted to the arrow B direction vertical with this arrow A direction by holding plate 25, the outer circumferential side of the filter material 24 in guiding current direction downstream.Thus, the water that flows into filter housing 14 inside can flow to inside from the outer circumferential side of filter material 24 cylindraceous, thereby can obtain the suitable current that filtered by filter material 24., filter 11 can be brought into play effective filtration.Further, holding plate 25 has the effect of pressing filter material 24 upper ends.Thus, even if for example in the case of the overlapping coiling of the cloth of filter material 24 does not align, also can press from top this unjustified cloth, thus can eliminate because of cloth unjustified carry out the undesirable condition that overlapping coiling causes.
Below, illustrate its example.The reason of the unjustified and overlapping coiling of cloth for example has, and as shown in Fig. 5 (b), cannot will form correctly overlapping being wound on filter core member 23 of cloth of filter material 24.For example, 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 is outstanding from end sometimes.Filter material 24 about the state that a part for this cloth is protruded to top is arranged on the situation in filter 11, and the state of Fig. 1 (a) before using this filter 11, the action state before that supplies water represents as an example.That is to say, be under the outstanding unjustified state in the upper end of filter material 24 cylindraceous, holding plate 25 is lifted to higher than normal installation site.Like this, the upper end that is bonded on the filter core member 23 at holding plate 25 back sides originally to be close to state becomes unsteady, produces the gap S2 of above-below direction between the back side of holding plate 25 and the upper end of filter core member 23.
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 end and holding plate 25 of filter material 24, the gap that does not in fact produce above-below direction is for well, but sometimes irregular or be formed with discontinuously gap S3.And the front portion of this gap S3 is connected with gap S2, S1.Then, the water flowing resistance by these gaps S3, S2, S1 is significantly lower than by the water flowing resistance of filter material 24.The water of, filling in filter housing 14 more easily passes through gap S3, S2, S1 than filter material 24.
Keep in the situation of this state water supply start action, once water is filled in filter housing 14, as shown by arrow G, water starts to flow into by gap S3, S2, S1, and water is subject to tap water pressure and passes through from the outer peripheral face side of filter material 24 originally, thereby all water is effectively filtered.In this case, the distribution of gap S3 easily expands to horizontal direction, thereby causes 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 the part distortion of outstanding cloth while flows into.Therefore, even if discontinuous gap S3 is originally accompanied by current and is out of shape, thereby force to form continuous clearance channel.Then, continuous gap S2, the S1 of the private side of this Yu gap, path, gap S3 be in connected state, thereby these gaps S3, S2, S1 are connected and form path, gap.Then, water flows into by these paths, gap, and the water flowing into by path, the gap after filtration hollow bulb of core component 23 flows out to the outside of filter 11.That is to say, filter 11 cannot be removed to the water performance of flowing out by path, gap the filtration of the script of the impurityes such as iron rust, probably causes being directly 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 bears the mobile hydraulic pressure of the running water of flow arrows A direction.Thus, the pressure-acting of direction of pressing this holding plate 25 is on holding plate 25.Like this, even if there is ledge in a part for cloth that forms filter material 24, this ledge is also kept plate 25 and presses.That is to say, press the masterpiece of holding plate 25 for dwindling the direction of gap S3, also act on the direction of the gap size that dwindles gap S2.Therefore, can eliminate these gaps S3, S2.
Describe according to Fig. 1 (b), after eliminating gap S2, S3, can effectively carry out the filtration of water.And, can be from the outside of transparent shell main body 19, the pollution condition of the filter material 24 that caused by impurityes such as iron rust of detecting by an unaided eye, thus can easily judge replacing period of filter material 24.Further, be overlappingly involved in the unjustified situation of end face that cloth causes filter material 24, can occur too in bottom.But in this case, nearly all weight of filter material 24 is all added in the outstanding position in filter material 24.Therefore,, if filter material 14 is housed in to the assigned position in filter housing 14, can maintain the suitable state that does not produce gap.
On the other hand, Fig. 6 and Fig. 7 represent the variation about holding plate 25.Fig. 6 (a) is the stereoscopic figure of holding plate 25, and Fig. 6 (b) is the cutaway view of holding plate 25.This variation is provided with concavity portion 29 on holding plate 25.This concavity portion 29 is at the surperficial central portion of the tabular surface of formation main part 26, recessed circular shape.This concavity portion 29 is formed on the concentric position corresponding with the supporting teat 27 of rear side.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 the position of the water that direct reception flows into from inflow entrance 15.
According to this structure, the water flowing into from inflow entrance 15 is under the received situation of tabular surface of holding plate 25, and it directly disperses to horizontal direction.But the water flowing into from inflow entrance 15, under the received situation of concavity portion 29, has stopped this water because the internal perisporium portion of this concavity portion 29 forms resistance, thereby can improve the hydraulic pressure that holding plate 25 is subject to according to tap water hydraulic.Like this, owing to having promoted to press the effect of holding plate 25, thereby can make reliably holding plate 25 and filter core member 23 chimeric.In addition, the upper end of filter material 24 can be pressed by holding plate 25 with stronger pressure, thereby the gap S3 that being easy to as shown in Fig. 1 (a) produces can be more effectively suppressed.
On the other hand, Fig. 7 (a) and (b) represent different variation.This variation, in the holding plate 25 that possesses basic structure, has formed the perpendicular wall portion 30 erectting upward in the periphery of main part 26.By forming 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 resistance that the perpendicular wall portion 30 of its peripheral part forms disperse water is to stop this water.Therefore, holding plate 25 can improve by the hydraulic pressure of running water the hydraulic pressure of reception.Like this, can promote to press the effect of holding plate 25, make holding plate 25 and filter core member 23 chimeric reliably.In addition, the upper end of filter material 24 can be pressed by holding plate 25 with stronger pressure, thereby the gap S3 that being easy to as shown in Fig. 1 (a) produces can be more effectively suppressed.Further, in this variation, owing to having formed large diameter concavity portion 31 on the almost whole surface of main part 26, thereby can expect all to carry out for holding plate 25 effect of pressing of a part for the stable effect of pressing rather than deflection holding plate 25.In addition, because the internal capacity of concavity portion 31 is large, thereby can receive a large amount of water, under the pressure of running water, can increase the effect of pressing holding plate 25 by the further w of the weight loading of large water gaging.
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 filter 11 for removing the impurityes such as iron rust.Thus, can avoid the feed water valve fault that causes because of sneaking into of impurity or the generation of iron rust, in addition, also can solve the problem such as pollution and variable color of washings.And, can increase the free degree that can use water source, do not used the water resources situation restriction of region and be effective as washings utilization.
Then, filter 11 is housed in filter material 24 in this filter housing 14.This filter material 24 is wound into tubular by overlapping cloth, and remains on filter core member 23.In addition, filter 11 possesses discoid holding plate 25.This holding plate 25 is supported in the top of filter core member 23, covers the upper end of filter material 24 from top.This holding plate 25 directly receives and flows into the water of filter housing 14, and changes current and be distributed to peripheral direction.Thus, holding plate 25 makes water lead to central side from the outer peripheral face side of filter material 24, effectively promotes filtering function.And holding plate 25 is covered with filter material 24 from top.Like this, can directly flow into from the upper end side of filter material 24 by anti-sealing.
Filter material 24 forms by overlapping multilayer-wound cloth, thereby can carry out as expanded the suitable adjustment such as its filter area.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, overlapping coiling amount that can free adjustment cloth.Therefore, as cloth, the cloth that can freely select to utilize each families such as all clothes such as such as shirt or friperie etc., stocking, towel to have.Therefore, there is no need to make the contour valency of spent ion exchange resin to be 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 surface in the face of the arrow A direction shown in Fig. 1, thereby can directly receive the mobile hydraulic pressure of the running water mobile along arrow A direction.Side is pressed pressure-acting in the direction of this holding plate 25 in holding plate 25 like this, downstream.Thus, can maintain filter core member 23 is suitably entrenched in to the state on holding plate 25.In addition, even if a part for the cloth of overlapping coiling is outstanding from the end face of filter material 24, also can be pressed into the holding plate 25 arranging from the mode of top covering filter material 24.Like this, can dwindle and even eliminate the space being represented by gap S3, thereby can flow into by gap S3 by anti-sealing.In other words, can obtain from the mobile current of outer peripheral face side direction central side of the filter material 24 of tubular, namely carry out by filter material 24 water effectively filtering, thereby effectively utilize filter material 24 entirety.
Directly receive the holding plate 25 that flows into the water in filter housing 14, on the surface of main part 26 that forms flat condition, possess the jut 28 that is radiated entends from central side towards outside.Like this, water can be distributed to peripheral direction equably, inhibitory action is in the deflection of hydraulic pressure or the current of holding plate 25.Therefore, can not produce eddy current etc., can form current smoothly.
On the other hand, in the filter housing 14 of accommodating filter material 24, use the easy-disassembling-assembling connection unit based on external thread part and internal thread part, as the unit in conjunction with shell main body 19 cylindraceous 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 easy-disassembling-assembling bearing unit, adopt the structure that is fitted to the cylindrical wall portion 21 of shell main body 19 bottoms across gap S1.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 main body 19 with transparent resin material, thereby 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 its replacing period, thus can maintain suitable water supply action and the effective filtration for impurity.But, be not limited to only shell main body 19 is made as to transparent structure, for example filter housing 14 all can be made as transparently, 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 is all provided with concavity portion 29,31 on the holding plate 25 that receives the water in inflow filter housing 14, for stopping that current are at once to peripheral direction, i.e. horizontal direction dispersion.By these concavity portions 29,31, strengthen the effect of block water, thereby can improve the hydraulic pressure that holding plate 25 receives.Thus, can strengthen the effect of pressing holding plate 25, make reliably holding plate 25 and filter core member 23 chimeric.In addition, the upper end of filter material 24 can be pressed by holding plate 25 with stronger pressure, thereby the generation of gap S3 can be more effectively suppressed.Therefore, can obtain effectively filtering required current.Particularly in the variation shown in Fig. 7, the effect of pressing that can all play stably to holding plate 25.In addition, because the internal capacity of reception water is large, thereby can further promote the effect of pressing by the weight of block water.
Further, holding plate 25 and filter core member 23 are assembled by different component respectively, but are not limited to this, and for example holding plate and filter core member also can form one.In this case, can unify and carry out easily the dismounting operation of 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), and Fig. 9 is the figure that is equivalent to Fig. 4.
Filter 11 remains on filter material 24 outside of filter core member 23.And filter material 32 is remained on filter core member 33 inside by filter 38.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.On the perisporium of filter core member 33, be formed with multiple cancellate reach through hole 33a.The diapire central portion of filter core member 33 is formed with the circular 33b of hole portion.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, because filter core member 33 has large diameter wide lower portion, so even if the height of cylindrical wall portion 36 is lower, it also can not be toppled 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 state of deviation position.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 align member of the collecting position supporting filter core member 33 in regulation and significant.
Then, holding plate 34 possesses the circular supporting teat 35 of giving prominence to from the peripheral end of discoid main part 37 integratedly downwards.Thus, holding plate 34 can chimericly be bearing in one end of the tubular of filter core member 33, i.e. upper end.That is, supporting teat 35 there is the internal diameter larger than the external diameter of filter core member 33, and and filter core member 33 between there is gap S1.Thus, holding plate 34 is chimeric and be bearing on filter core member 33 with easy-disassembling-assembling state.
On the other hand, filter material 32 is forms of overlapping coiling cloth itself, preferably uses as far as possible the cloth of long size.But, even if short cloth, also can be by supplementing at any time cloth with by its overlapping multilayer that is wound into, thus can form the large diameter cylindric filter material 32 of the radial dimension with expection.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 in the inner degree that produces gap of filter core member 33.
Further, the arrow A shown in Fig. 8 to arrow E represents water (flow) direction, and it represents the current identical in fact with the current that represent with prosign in Fig. 1 (b).Further, in this case, flow path is the water inner filter material 32 of flowing through after by filter core member 33, and in this, they are different from the current of above-mentioned embodiment.In addition, because the central part of filter material 32 is ends that cloth roll gets around the beginning, so overlapping situation between cloth, degree of being close to is less.Like this, as shown by arrow D, have the tendency of stream downwards at the water of filter material 32 central parts, therefore, as shown by arrow E, water flows out swimmingly from the flow export 16 of below.
According to this embodiment, the basic function of filtering function, holding plate 34 and filter core member 33 etc. based on filter material 32, as all functions of filter 38 is identical with the first embodiment in fact.But, because filter material 32 is housed in to the inside of filter core member 33, so form the form that covers the upper end of filter material 32 and surrounded the lateral surface of filter material 32 by filter core member 33 by holding plate 34.Like this, the filter material 32 of overlapping coiling can be not at random.Further, each constituent part of exploded representation filter 38 in Fig. 9.Filter material 32 grades are arranged in filter housing 14 and are set in the situation of serviceable condition, if in advance filter material 32 being accommodated under the state remaining in filter core member 33, be housed in shell main body 19, can be more easily carried out the assembling operation of filter material 32 and filter core member 33.
Further, in each embodiment described above, all adopt the structure that filter material is remained on to filter core member.But the various distortion that can carry out that such as obstructed filtration core component keeps etc. or expansion are implemented.
Figure 10 is the figure that is equivalent to Fig. 1 (b) that represents other embodiments.The filter material 32 that by identical with the filter material 32 illustrating in example the second embodiment as shown in Figure 8 in fact filter material, this filter 39 is only formed by the overlapping coiling of cloth, 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 the weight forming by multiple-layer overlapped coiling cloth to load with upright state.Therefore, about the bottom of shell main body 19 that has loaded filter material 32, the limbers 19b of the flow export 16 below central portion only has connection is opening, and 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, be bonded on the back side of its flat condition under the state of filter material 32 upper ends by mounting supporting.Further, the central part at the back side of holding plate 40 is formed with outstanding protuberance 41 a little downwards.This protuberance 41 is inserted into end that filter material 32 starts to reel, the i.e. gap etc. of central part, prevents thus the position deviation of holding plate for filter material 32.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 receives the water from inflow entrance 15 as shown by arrow A, and by current be converted to shown in arrow B laterally.Then, water is along the sequential flowing of arrow C, D, E, thereby can bring into play well in fact in the same manner with the respective embodiments described above the filtration of filter material 32.In addition, the hydraulic pressure of the water that holding plate 40 flows into along arrow A direction by reception, thus support reliably with the state that joins filter material 32 upper ends to.Thus, can bring into play the function as holding plate 40.In addition, can not use the filter core member of supporting filter material 32 use etc., thereby the filter 39 of simple cheap can be provided.Further, according to kind of cloth etc., the coiling of some filter material 32 finishes end and likely can peel off.In this situation, for example, can tie up by rope class etc. at the Zhou Fangxiang of filter material 32.As rope class, for example, there are cotton thread or elastic tape etc.

(the 3rd embodiment)
Then, with reference to Figure 12 to Figure 19, be, in washing machine, to use the 3rd embodiment of filter to describe to washing facility.
Figure 19 represents to be used in two-tub washing machine 101(hereinafter referred to as " washing machine 101 ") the stereoscopic figure of use state of filter 102.In this case, Figure 19 also represents to use the arrangement states of filter 102.Form in the main body 103 of gabarit of washing machine 101, be set side by side with well-known sink and drench pit, omit diagram herein.Form on the top cover 10 of upper surface of this main body 103, be provided with washboard 105 to be opened/closed and dehydration and cover 106, its rear possesses the guidance panel 107 for setting various operation contents.
Guidance panel 107 is provided with feed water inlet 108, for the not shown sink that supplies water from external water sources such as running water.Directly over this feed water inlet 108 almost protrudes from linearly.Install after filtration 102 watertights from the supply of water of external water source and the hose of cut-out 109 and flexual water supply hose 110 and be communicated to this feed water inlet 108 for switching.This filter 102, for the impurity of filtered water, describes in detail subsequently to this.This filter 102 is arranged on from external water source to feed water inlet 108(washing machine 101) so-called water supply path.Further, can adopt pipe clamp 111 at the connecting portion of water supply hose 110 as required.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 longitudinal section, the cutaway view of Figure 17 and the exploded perspective view of Figure 18 of Figure 16, this concrete structure is described.Filter 102 is formed as the cylindrical vessel shape of hollow on the whole, and it possesses filter housing 112 and filter core unit 113.Filter housing 112 is in its one end, center upper portion portion has inflow entrance 116, at the other end, the central portion of bottom (bottom) has flow export 117.Filter core unit 113 is housed in this filter housing 112.
Filter housing 112 is made up of the cover 115 that has the shell main body 114 of bottom tube-like and watertight and cover the upper surface of this shell main body 14.These shell main bodys 114 and cover 115 are all ester mouldings.In this case, at least shell main body 114 for example, is formed by transparent resin material (acrylonitrile-styrene resin, polycarbonate resin, acrylic resin), thereby can have an X-rayed inside.Flow export 117 is given prominence to downwards with cylindric in the bottom (bottom) of shell main body 114.Inflow entrance 116 is given prominence to upward with cylindric above cover 115.
On the outer circumferential side of this cover 115, be formed with external thread part 115a.The inner side of the open end of shell main body 114, is formed with the internal thread part 114a corresponding with external thread part 115a.Link these threaded portions 115a, 114a by the sealing ring 118 shown in Figure 16, thereby form filter housing 112.In this filter housing 112, shell main body 114 and cover 115 when watertight combination, are formed as removable structure each other.Further, as shown in figure 16, on cover 115 inflow entrance 116, be connected with the water supply hose 110 representing with double dot dash line, on the flow export 117 of bottom 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 osculum 119 that diameter is less than flow export 117.The cylindrical wall portion 120 of toroidal protrudes near medial surface osculum 119.As shown in Figure 17 and Figure 18, be provided with the slot part 121 forming by a part for cutting cylindrical wall portion 120.This slot part 121 communicates with osculum 119 and flow export 117.Further, the flow export 117 of outer bottom by sealing ring 122 watertights be fitted to the feed water inlet 108 of washing machine 101.Thus, as shown in figure 16, filter housing 112 is kept with substantially vertical upright state.Like this, the diameter of osculum 119 is less than flow export 117 so that sealing ring 122 to be installed.This osculum 119 as the outlet for draining of filter housing 112, is being brought into play common effect in fact.
Next,, with reference to Figure 14, Figure 15, the structure that is housed in the filter core unit 113 in the filter housing 112 of said structure is described.Figure 14 is the stereogram of filter core unit 113, and Figure 15 (a) is the side view of filter core unit 113, and the cutaway view of filter core unit 113 is cut off in Figure 15 (b) expression along the A-A line in Figure 15 (a).Figure 19 represents the use state of filter 102.Conventionally, specifically as shown in figure 16, filter 102 is positioned under the state of sensing above-below direction that top, flow export 117 is positioned at bottom and uses at inflow entrance 116.Then, as shown in figure 16, filter core unit 113 is accommodated with the state being erected in filter housing 112.Filter core unit 113 at least between the internal face of filter housing 112, i.e. upper wall surface 112a and peripheral wall surfaces 112b gapped state 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, and described holding plate 123 is for example formed as by integrally formed discoid of acrylic resin, and described filter core member 124 extends downwards in the rear side of this holding plate 123.Like this, in filter core unit 113, gapped and mutually opposed between holding plate 123 and inflow entrance 116.In addition, the opening dismounting of filter core member 124 lower ends is entrenched in the outside of cylindrical wall portion 120 freely.As shown in figure 16, filter core member 113 is accommodated in filter housing 112 under this bearing state.But, make filter 102 in the spendable state that arranges, after need to filter material 128 coilings being installed on to filter core member 124 under the state that takes off cover 115, accommodating this filter core unit 113, thereby form installment state, this is described in detail subsequently.
As shown in figure 14, form the holding plate 123 of filter core unit 113 and possess integratedly multiple (for example 4) jut 125 that is radiated entends from the central part of the upper surface of flat condition.This jut 125 except with the opposed centre of opening of inflow entrance 116 position be formed as radially, and be formed as protruding separately vertical tabular shape.Further, this radial jut 125 receives the water flowing into from inflow entrance 116, and these current are evenly spread to peripheral direction, afterwards its effect is elaborated.Therefore, jut 125 is not limited to tabular, can be for example chevron cross section, or can not be also the shape of continuous 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, has for example cancellate 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 124, thereby need not be set to same shape.In addition, as shown in figure 16, as the shape of filter core member 124 cylindraceous, its diameter dimension is designed to, diameter dimension in the cylindrical wall portion 120 of the dismantled and assembled bottom that is entrenched in freely shell main body 114, filter material 128 is being arranged under the state of the perisporium with reach through hole 124a, and between the medial surface of shell main body 114, there is the diameter dimension of specified gap simultaneously.
As shown in figure 16, be contained in the filter core unit 113 in filter 102, the gap forming between the internal face of filter 102, i.e. upper wall surface 112a and peripheral wall surfaces 112b, as playing a role to the mobile water stream channel of the direction of arrow in figure.Water is by being installed on the whole surface of filter material 128 of filter core member 124,, is supplied in not shown sink through the feed water inlet 108 of washing machine 101 from reach through hole 124a and flow export 117.
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 length range of the direction (being called below, " length direction " of cylinder) to cylindric extension.For example linearly opening of this slit-shaped 126.In addition, the gap size between the opposed perisporium of this slit 126 both ends is that A/F is formed as, and can clamp the narrow and small width dimensions of filter material 128 ends, and this is described in detail subsequently.And as shown in Figure 15 (a) and (b), the upper end of the perisporium that comprises this slit 126 is formed with the almost grooving portion 127 of half cycle.That is to say, the part that forms grooving portion 127 is formed with gap, and by this gap, a part for filter core member 124 separates with holding plate 123.In addition, by this gap, become the easily shape of strain across the opposed all end wall of slit 126.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 seating means of being installed on filter core unit 113 etc. describe.First, as the material of filter material 128, for example, utilize the material that nonwoven fabric is thinly sliced.But as the material of filter material 128, it is not limited only to this, also can use the soft cloth that can be wrapped in filter core member 124 periphery walls.Therefore, friperie also can utilize with the clothing materials of not wanting etc.In addition, as the size of filter material 128, nonwoven fabric is cut into the laminar of rectangle, makes its length dimension be greater than the size (size of circumferencial direction) of the whole circumference of filter core member 124 perisporiums, 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, the laminar filter material 128 that is cut into regulation shape is attached to the peripheral wall surfaces in its outside.Then,, as shown in Figure 12 (b), insert in the mode that one end of this filter material 128 is pressed into slit 126.Keep this state, by another distolateral being wrapped on filter core member 124 of filter material 128.Then, as shown in Figure 12 (c), in the time of the position of another distolateral arrival slit 126 of filter material 128, by this another distolateral insertion slit 126.In this case, owing to being that resin is made across the both ends of slit 126 in filter core member 124, thereby possesses 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, the both ends across slit 126 in filter core member 124 are more rich in elastic force, even if do not apply also strain easily of undue external force.
Therefore, to the pressing and make its distortion across the opposed both ends of slit or an end of filter core member 124, thereby expand slit 126, in this state, can easily insert filter material 128 another is distolateral.Then, insert another of filter material 128 distolateral after, if except the external force (pressing force) of whereabouts filter core member 124, filter core member 124 flexibly returns to original-shape, thereby in its A/F, flexibly clamps the both ends of filter material 128.That is to say, by the perisporium both ends across the opposed filter core member 124 of slit 126, 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.That is, be inserted into inside 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 126, its insertion is equivalent to the part having more than the circumferencial direction size of the periphery wall of filter core member 124.
Like this, the filter core unit 113 that filter material 128 is installed to be housed in filter housing 112 and make it in the spendable state that arranges, the filter core unit 113 that filter material 128 is installed need to be housed in shell main body 114 under the state that takes off cover 115, and make the outside of the chimeric cylindrical wall portion 120 that is bearing in filter housing 112 inner bottom parts in bottom of filter core cylindraceous unit 113.Now, the both ends of the filter material 128 inserting from slit 126 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 the slot part 121 of fluting state.Thus, be entrenched in cylindrical wall portion 120 by the position that makes slit 126 with the mode that this slot part 121 aligns, thereby the both ends of filter material 128 can be stored in slot part 121.That is to say, slot part 121 played a role as 128 the keeping out of the way portion of both ends of filter material.Thus, can successfully with reliable and stable chimerism, filter core unit 113 be set.In addition, the width dimensions of filter material 128 than the size of the length direction of filter core member 124 cylindraceous large several millimeters.Therefore, can be easily wound around filter material 128 in the mode on the whole surface that covers filter core member 124 perisporiums.But, the bottom of the filter material 128 after installation is outstanding a little.But, can by the flexibility of filter material 128 itself or after arranging the total weight of filter core unit 113 be applied to the lower end of filter material 128, thereby filter material 128 is set to the bottom (cylindrical wall portion 120) of shell main body 114 under shakedown.
Afterwards, cover 115 is arranged in shell main body 114.Then, as shown in figure 19, by water supply hose 110 grades, outside watering and washing machine 101 are coupled together, thereby set the state that can supply water to washing machine for, and then can be by the operation water supply start action of the tap 109 of fetching boiling water.Further, about this washing machine 101, also have such washing machine, the downstream of its feed water inlet 108 possesses the feed water valve of not shown for example electromagnetic type, can automatically start washing operation according to the action of supplying water.In this case, can make in advance hose 109 in open mode.Then, control the switching of electromagnetic type feed water valve by the control device of washing machine, thereby can carry out the water supply action by filter 102.
Then, the effect of the filter 102 using in the washing machine 101 of above-mentioned formation is described.
By the tap 109 of fetching boiling water, be supplied to not shown sink through water supply hose 110, filter 102, feed water inlet 108 from the running water of external water source.Then,, when supplied with the water of the regulation water yield in sink after, by closed tap 109, can stop the action of supplying water.Afterwards, user's operating operation panel 107, sets the washing working procedure of expectation etc., and brings into operation.Thus, carry out general well-known washing operation.
At this, the effect of the filter 102 in above-mentioned water supply action is elaborated.As mentioned above, filter 102 is arranged in the water supply path of washing machine 101.Therefore, be accompanied by opening of hose 109, running water arrives filter 102.Figure 16 represents this filter 102 to be set to spendable state, describes with reference to Figure 16, and water flows in these filter housings 112 from the inflow entrance 116 on the top of filter 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 the state of inflow entrance 116.Therefore the water, flowing into from inflow entrance 116 flows in the surperficial mode at the substantial middle position of impact holding plate 123.At this moment, produce to pressing the mobile pressure of direction at holding plate 123.This pressure-acting is embedded in the direction of cylindrical wall portion 120 at filter core member 124.Therefore, filter core member 113 can stably maintain the state arranging of erectting.Then, the flow direction of the water of inflow is converted to right angle orientation, to the peripheral direction diffluence of holding plate 123.In this case, on the surface of holding plate 123, be provided with multiple (for example 4) the radial jut 125 extending from center side direction outer circumferential side.Guide the dirty water to peripheral direction by these juts 125, under the homodisperse rectified action of circumferencial direction, flow swimmingly and do not produce the sinuous flows such as useless eddy current.
Then, above filter core unit 113 and side, current, through the gap as between internal face passage and filter housing 112, flow down downwards along the medial surface of filter housing 112 from the outer circumference end of holding plate 123.This water that flows to below immerses from the below of filter material 128 gradually.In this case, according to form the material kind such as cloth of filter material 128 and output number 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 128, this water flowing resistance can change.
Consequently, tap water hydraulic is applied in filter housing 112, and it is all that water circulates in rapidly water through filter material 128.Particularly, water flows out to central side through the reach through hole 124a of inner filter core member 124 from the outside of filter material 128.Then, water, through osculum 119 and the flow export 117 of filter housing 112 bottoms, is supplied to the feed water inlet 108 of the washing machine 101 shown in Figure 19, in not shown sink, supplies water.Like this, all water of supplying with from hose 109 are all by filter material 128 and be filtered.Thus, can effectively remove iron rust and the small impurity etc. of in running water, sneaking into, the clean water that has filtered impurity is supplied to washing machine 101.
Then,, after supplying water to sink, closed tap 109, stops supplying water.After water supply stops, thering is water residual in the water supply path of filter 102 and slowly flow out to sink.At this, the processing of residual water in filter device 102 is described.As shown in Figure 16, water mainly flows out from osculum 119 through the reach through hole 124a of filter material 128 and filter core member 124.But, once the water level in filter 112 drops to the low water level lower than the reach through hole 124a of foot, the inner peripheral portion of filter core member 124 bottoms and be positioned at its inner cylindrical wall portion 120 and likely can stop water to circulate to osculum 119.
But filter 102 is formed with slit 126 in the total length of the length direction of filter core member 124 cylindraceous.And this slit 126 is entrenched in the position corresponding with the slot part 121 that is formed on cylindrical wall portion 120.As shown in figure 17, according to this structure, the both ends of the filter material inserting from slit 126 128 can be stored in slot part 121., slot part 121 played a role as the keeping out of the way portion of both ends of the filter material 128 inserting from slit 126.In addition, slit 126 forms the passage that is communicated to osculum 119 through slot part 112.Therefore,, even if become low water level in filter housing, water also can flow and get rid of from flow export 117 to arrow indicated direction in Figure 17 through this passage.
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 128 be 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 blocked state that the impurityes such as the iron rust of being caught by filter material 128 cause develops gradually.Because filter housing 112 is transparent resins, thereby can, by the pollution condition of the filter material 128 that detects by an unaided eye from outside, easily discover this mesh blockage.Therefore, the mesh blocked state of filter material 128 be can easily distinguish at any time, the period of the impurity of removing filter material 128 or the replacing period of novel filter material can not be missed.Thus, always can maintain good strainability.
And user can easily carry out the disassembly and assembly operation of filter 102.This field-strip is described, in water supply hose 110 water supply paths such as grade, can easily take off by the chimeric filter connecting 102.Then, in the filter 102 that this takes off, dismounting filter housing 112., filter housing 112 forms by shell main body 114 and by the cover 115 that the 114a of internal and external threads portion, 115a are screwed to this main body water tank 114.Therefore, can, only according to the simple operation of rotation operation cover 115, separate these main body water tanks 114 and cover 115.Thus, can, from the upper surface open of the shell main body 114 opened, take out the filter core unit 113 that comprises filter material 128.In this case, the bottom dismounting of filter core member 124 is entrenched in the cylindrical wall portion 120 of shell main body 114 freely, and 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 is flexibly clamped in filter core member 124 across between the perisporium both ends of slit 126.Therefore, for example, press the side in these both ends from filter material 128, this part generation strain, the A/F of slit 126 also expands.Therefore, can from slit 126, pull out by one side pressing operation the end of filter material 128 on one side, easily the end of filter material 128 be freed.In addition, by by the side tractive lightly of the filter material freeing from clamp position 128, the opposite side of remaining filter material 128 can be taken off.
For example can be by washing, the impurity that the filter material taking off 128 is caught is removed.Or, filter material 128 is replaced by new filter material.Like this, again, filter material 128 is arranged on the filter core member 124 of filter core unit 113.Further, the erection sequence of filter material 128 as shown in figure 12.In addition, after being assembled into filter 102, the reverse order during according to above-mentioned dismounting is arranged on this filter 102 in water supply path, also can easily carry out fitting operation.
As described above, according to the 3rd embodiment of filter 102 that is applicable to washing machine 101, can expect to obtain following effect.
In 101 water supply path from external water source to washing machine, filter 102 is set, thereby the water after the purification of having filtered the impurityes such as iron rust can be provided.Thus, can eliminate the harm of iron rust to washings etc.In addition, can be easily from filter 102, installation or removal are for catching the filter material 128 of the impurityes such as iron rust.Particularly, as shown in the erection sequence of the filter material 128 illustrating according to Figure 12 (a) and (b), (c), laminar filter material 128 can be wound on the perisporium of cylindric filter core member 124 of resin manufacture, in the slit 126 that the both ends insertion perisporium of the top portion of this filter material 128 and terminal part is provided with, thereby flexibly grip.
This means that grip are being arranged on filter material 128 on filter core member 124, or while taking off filter material 128 from filter core member 124, 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 strainability of expection.In addition, because filter housing 112 is made up of transparent resin, thereby the filter material 128 that can detect by an unaided eye from outside, easily judge this mesh blocked state according to pollution condition etc.Therefore, can not miss the period of cleaning or changing filter material 128, very easy to use.
And, due to the harvesting of the top portion of filter material 128 and terminal part is clamped in slit 126, thereby can clamp reliably the both ends of the filter material 128 that is easy to peel off.In addition, a filter material 128 can be wound on to the roughly whole peripheral wall surfaces of filter core member 124 with thickness equably, obtain uniform water flowing.Thus, can, at the almost whole surface performance filtering function of filter material 128, can expect the better strainability of efficiency.And, as the material of filter material 128, can use the cloth such as nonwoven fabric, friperie of thinly slicing shape according to the size of reeling.Therefore, in general family, easily prepare material, low price and the practicality of filter material 128.
In addition, in order flexibly to clamp top portion and the terminal part of filter material 128, holding plate 123 and filter core member 124 combine in one piece.But the inner peripheral portion that comprises slit 126 separates with holding plate 123, that is to say, to form the mode in gap, grooving portion 127 is set.Thus, become and be easy to deflection across two inner peripheral portion of slit 126, increase thickness even if for example consider the intensity of resinous filter core member 124, also do not need large pressing force can make its strain, can easily clamp filter material 128 according to handwork.But holding plate 123 and filter core member 124 can not be integrally formed, can be also for example by the structure of the strong bonded such as binding agent.In this case, replace grooving portion 127, as the gapped structure of position tool in this grooving portion 127, integratedly in conjunction with holding plate 123 and filter core member 124, that is to say combination integratedly under the state that holding plate 123 is separated at gap portion with a part for filter core member 124.
And then, the structure of accommodating and arrange the filter core unit 113 that filter material 128 has been installed in filter housing 112 is as follows: make cylindrical wall portion 120 protrude near the inner bottom part flow export 117 of filter housing 112, by one end of filter core member 124, lower ending opening is entrenched in this cylindrical wall portion 120, thereby with dismounting freely and stable state supporting filter core unit 113.But, if do not taken measures, the end phase mutual interference of the filter material 128 that cylindrical wall portion 120 can insert with the slit 126 from filter core member 124.That is to say, mutually conflict and produce obstruction in the end of cylindrical wall portion 120 and the filter material 128 that inserts from slit 126, filter core member 124 cannot be entrenched in cylindrical wall portion 120 reliably.
Thus, slot part 121 is set in cylindrical wall portion 120.Osculum 119 and flow export 117 are led in one end of this slot part 121, and the other end is corresponding with the slit 126 of filter core member 124.Therefore, the end of the filter material inserting from slit 126 128 can be stored in to slot part 121.Thus, filter core member 124 is chimeric with cylindrical wall portion 120 and be stably supported reliably.And then slit 126, slot part 121 and flow export 117 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.

And then, be arranged on water supply path outside washing machine 1, i.e. bactericidal device 56 in the water flowing path of water supply hose 45, by the wire 53 of the core component 52 along this second flexible pipe 45b, be electrically connected to washing machine 1 side.For example, as shown in figure 30, ultraviolet lamp 59 and the level sensor 71 of bactericidal device 56 are connected to control circuit 72 by connector 51.Control circuit 72 can be accompanied by the operation of washing machine 1, and the action of bactericidal device 56 is controlled.Further, the symbol 5a shown in above-mentioned Figure 30 and symbol 72 be to symbol 77, the symbol of just giving for this Figure 30 is described.
Next, in the washing machine 1 of supply-water pump 44 that possesses said structure, the effect of the water purification units 47 when action is supplied water in main explanation.But, about the filter 11 that forms water purification units 47, because it is identical in fact with the effect of the first embodiment illustrating, thereby only make schematic illustration.In the present embodiment, carry out the operation that has utilized the built-in supply-water pump of washing machine 44.In this case, as shown in figure 29, the water supply hose 45 shown in Figure 26 is connected to pump and uses feed water inlet 43 detailed content.And, meanwhile, between bactericidal device 56 and the control circuit 72 of washing machine 1 side, by the wire 53 of core component 52 arranging along helical form in the second flexible pipe 45b of water supply hose 45, form electrical connection.
Under this state, user drops into after not shown washings, washing ready for operation in cell body, the only operating portion 5a of guidance panel 5 shown in Figure 30 of operation, and setting utilizes the washing working procedure of supply-water pump 44 etc., and brings into operation.Turn-sensitive device 75 shown in Figure 30 detects the revolution (rotary speed) of the motor 74 of initial operating stage, and this detection signal is outputed to control circuit 72.The control circuit 72 of input detection signal determines the weight of washings and necessary water level.Once supply water to predetermined water level, control circuit 72 detects this water supply by level sensor 73 and arrives this situation of predetermined water level.Then, control circuit 72 cuts out supply-water pump 44, finishes the action of supplying water.Thus, the washing operation that starts to wash clothes.
Like this, washing machine 1 has utilized supply-water pump 44 in water supply action.At this, illustrate the situation of for example utilizing water for bathing to supply water as external water source.As shown in figure 26, once supply-water pump 44 is driven, it sucks water for bathing by the water sucking mouth 46 being invested in bathtub, send water by water supply hose 45 along solid arrow direction.Supply water in way at this, water for bathing purifies via water purification units 47.Then, water for bathing is supplied in cell body by feed water inlet 43, supply-water pump 44 and private water supply flexible pipe 48 as shown in figure 29.Further, in Figure 29, represent the flow direction of water for bathing with solid arrow.
Next, the effect of above-mentioned water purification units 47 is described according to Figure 25.Water for bathing is supplied in filter 11 from the first flexible pipe 45a at first.As shown in the solid arrow of Figure 25, water is guided by holding plate 25 and flows to peripheral direction in the mode of diffusion, and is the side square through-flow inwardly of filter material 24 cylindraceous from package.Now, the various impurityes in water are filtered and are removed.So filter the water for bathing of impurity, flowed to below and flow into bactericidal device 56 sides by joint member 64.Certainly, now, drain cock 66 is made as closed state by manual operation or electric operating.Therefore the water route that, leads to drainpipe 65 sides is in closed state.
The water (water for bathing) flowing into from the bottom of bactericidal device 56 sides rises from the below in degerming case 58.Then, almost flood all high water level of ultraviolet lamp 59 once the water level in degerming case 58 arrives, level sensor 71 detects as reaching high water level.As shown in figure 30, reception controls to light the luminous tube 59a of ultraviolet lamp 59 from the control circuit 72 of the detection signal of this level sensor 71, and to the water irradiation ultraviolet radiation of flowing through in degerming case 58.Ultraviolet lamp 59 starts ultraviolet irradiation under the state being almost all in water.Thus, can and carry out efficiently the bactericidal action to miscellaneous bacteria in water without waste.
And then, if proceed the water supply action based on supply-water pump 44, purify and flow into washing machine 1 from the flow export 62 on degerming case 58 tops through the second flexible pipe 45b by the water of ultraviolet lamp 59 sterilizations by filter 11.Particularly, as shown in figure 29, the feed water inlet 43 that water for bathing is used from pump is drawn in supply-water pump 44, and the private water supply flexible pipe 48 of then discharging side from being connected to this pump 44 is supplied in cell body.The action of supplying water like this, the water level in cell body reaches predetermined water level in the near future, and the level sensor 73 that is located at cell body side can detect the situation that reaches predetermined water level.According to this detection signal, control circuit 72 stops the driving of supply-water pump 44 to finish the action of supplying water, and also cuts off the energising of ultraviolet lamp 59 to close this ultraviolet lamp 59 simultaneously.
Afterwards, control circuit 72 is carried out the control same with the washing working procedure conventionally carrying out.That is, control circuit 72 is located at for example stirring body in cell body by driving, automatically performs the washing stroke that comprises washing agent and removes the rinsing stroke of washing agent, then, by rotation swivelling chute, automatically performs dehydration stroke.Further, as the water for bathing process water purification units 47 of washings, thereby be purified through the bactericidal action of removing impurity and sterilization.Therefore, can be used as rinsing water through the water for bathing of water purification units 47.Further, in this case, washing machine 1 also can be only uses running water in the time of final rinsing for example.In this case, the water supply hose of in advance water pipe being used is connected to the feed water inlet 7 shown in the Figure 26 for supplying with running water.At this moment,, as shown in Fig. 2 of the first embodiment, also can adopt by filter 11 way of supplying water in the water supply path that is connected to feed water inlet 7.
