Embodiment

Hereinafter, the example of embodiments of the present invention is illustrated referring to the drawings.

In addition, " filter of water purifier " in the present invention is at hereinafter referred to as " filter ".

The water purifier involved by one embodiment of the present invention is represented in Fig. 1.Fig. 1（A）Represent its front view, Fig. 1（B）Table Show its top view, Fig. 1（C）Represent its right side view, Fig. 1（D）Represent its stereogram.

As shown in figure 1, the water purifier 1 of present embodiment is made up of filter 2, installing plate 3 and pipeline 6 substantially, filtering Device 2 is made up of filter portion 4 and filter cylinder 5.Filter 2 possesses multiple, connects to the place for being used as water purifier by multiple pipelines 6 therebetween The running water of reason object can circulate.

The respective filter portion 4 of multiple filters 2 has the introducing port 7 and export mouth 8 as running water stream, filter 2 be for column, side possesses the form of entrance and exit at one end.The filter of this form with possessing entrance respectively in two sides Compared with the filter of outlet, pipeline can be connected the advantages of concentrating side at one end and compactly forming by having.Especially exist Possesses the water purifier of multiple filters, the advantage is notable.In Fig. 1（A）In, the introducing port 7 positioned at the filter portion 4 of left end is water purification The raw water introducing port 9 of device 1, on raw water introducing port 9, raw water ingress pipe is connected with via the tap prepared in addition, is supplied to Running water as raw water.In addition, in Fig. 1（A）In, the export mouth 8 positioned at the filter portion 4 of right-hand member is led for the water purification of water purifier 1 Outlet 10, the water purification delivery line prepared in addition is connected with, the other end of the water purification delivery line is directly or once via tap And it is connected on the water purification nozzle that water purification is discharged to user.

Multiple filters 2 are configured with the stream being connected between raw water introducing port 9 and water purification export mouth 10, are supplied to The raw water of raw water introducing port 9 is cleaned by multiple filters 2, is flowed out from water purification export mouth 10 as water purification.

4 filters 2 are linked with the water purifier 1 of Fig. 1 embodiment.It is referred to as successively from the upstream side of stream 1st filter, parallel configuration, the 2nd filter and the 3rd filter of connection, the 4th filter.This 4 filters are as profile shape Shape is identical, and linking can exchange on construction, but the filter material for being contained in its cartridge interior is different, has different filterings Function and mode.It is preferred that it is respectively following function, mode, structure.I.e., the 1st filter is prefilter, by the filtering of appropriateness Precision（About 1~10 μm of degree）Resin（Polypropylene, polyethylene etc.）Formed body that the non-woven fabrics of system or melt-blown are formed etc. is made For filter material, primary removal, filtering are carried out to the foul that can be present in running water or bigger particle shape impurity.Flowing The 2nd filter of parallel configuration and the 3rd filter are that have the identical or same pressure loss and strainability in road（Cross Filter ability or removing performance）Identical or congener adsorption filtration filter, using activated carbon etc. as filter material, to can Residual chlorine, stink included in running water, harmful organic matter（Haloform etc.）Etc. being adsorbed or decomposed removing.The 4 filters are the filters of membrane filtration, using hollow fiber membrane with micropore etc. as filter material, to that can be included in running water Small particle, cloud components, bacterium class etc. filtered.

Also can be the reality of the filter of the parallel configuration membrane filtration in the case that cloud components in running water etc. are more Apply mode.In such manner, it is possible to obtain the long lifetime of the strainability of the filter-portion of membrane filtration and the effect of pressure loss reduction Fruit.Equally, in running water it is more containing bigger foul etc. in the case of, also can be parallel configuration prefilter reality Mode is applied, this is also effective.

According to Fig. 1（B）Understand, four filters 2 are overlooked（From the end on observation of the filter 2 of column）When for two row match somebody with somebody Put and be interconnected.In addition, in the 2nd filter and the connecting line path of the parallel configuration of the 3rd filter（I.e., in order to Parallel configuration and from 1 branch, then collaborate again and return to the connecting line path of 1）In, the number of bends in path is in parallel connection It is twice in the either path of configuration.Moreover, in Fig. 1（B）In, the bending in the connecting line path is that angle of bend is right angle （90 degree）.That is, the aggregate value of the angle of bend in the connecting line path of parallel configuration is 180 degree.More than design Amount or fabrication error etc. and make the aggregate value of angle of bend for less than 200 degree be the scope of the present invention.Here, connecting line path In bending be defined as connecting line path formed bending, include only relate to filter interior stream bending.It is logical Often, there is stream bending in the inside by the filter formed with introducing port and the filter portion of export mouth and filter cylinder, the filter The aggregate value of the angle of bend of internal flow path is more than 200 degree.Therefore, the angle of bend in the connecting line path of parallel configuration is made Aggregate value for less than 200 degree be by the pressure loss in filter-portion reduction connecting line path, reduce and be used as water purifier The important and effective important document of the overall pressure loss.In the present invention, the bending in connecting line path makes connection including all The bending of angle, offer as the intentional pressure loss of stream as defined in state change of the direction in pipeline path from straight line, Angle of bend is the bending that the bending of angle, the bending of some circular arc beyond right angle also serve as 1 time.In the bending of circular arc In, define angle of bend to the mutual intersecting angle of tangent line of circular arc with the two-end-point of circular arc（With reference to Fig. 9 described later（B））. In addition, not only include the bending in the plane orthogonal with the axial direction of the filter 2 of column, also include to outside its plane（Upper and lower To）Bending.So, set if the aggregate value for making the angle of bend in the connecting line path of parallel configuration is less than 200 degree It is scheduled in the range of restriction, so by parallel configuration, the pressure loss of filter-portion can not only be reduced, even if as simultaneously Join the connecting line path of configuration, compared with conventional connected mode, can also reduce the pressure loss.Further, since bending time Number is parallel configuration filter twice, so the connecting line path as parallel configuration, can be installed as reasonably matching somebody with somebody Meter, so it is simpler than conventional connected mode, compact, the pressure loss can be reduced.That is, the pressure in connecting line path Loss will not damage pressure loss this purpose of the reduction filter-portion of parallel configuration.As a result, it can increase as net The flow of hydrophone.

In Fig. 1（B）Embodiment in, angle of bend is right angle（90 degree）Be bent into twice, formed with parallel configuration Connecting line path, but certainly also can be the smaller angle of angle of bend（Such as 45 degree）The other implementation bent twice Mode（With reference to Fig. 9 described later（A））.So, the small pressure loss that can further reduce in bending of the aggregate value of angle of bend. But in this case, need to make the pipeline path of straight line portion to compare Fig. 1 in order to avoid the mutual interference of filter（B）It is long, Lateral length as water purifier also lengthens therewith.

In addition, for example avoided for the facility in water purifier design with it is appendicular dry near filter or pipeline Relate to, also can be to bend in the connecting line path of parallel configuration more than number twice（Such as four times）Embodiment. In this case, due to the angle of bend of reduction first order buckling, the aggregate value for keeping angle of bend is less than 200 degree, so energy Enough reduce the pressure loss in connecting line path.

In Fig. 1（B）In, the connecting line path of parallel configuration becomes the path of same shape.So, can make Two connecting line paths of parallel configuration are the identical pressure loss.Moreover, the identical or of the same race of parallel configuration can be made The life-span of the filter 2 of class is substantially the same, eliminates some waste changed in the midway that can also be used, You Yu Tong Time Changed together, so the most economical.Of course it is also possible to the filter of parallel configuration variety classes, different performance, this is also wrapped Include in the present invention.

In addition, the distance between central shaft respectively arranged in two row of two row configurations is set to the outside dimension than filter 2 It is small.Due to being the parallel configuration of such two row, so compact configuration can be turned on depth direction, it is whole as water purifier Body is also compact.

And then in Fig. 1, the respective entrance and exit of filter 2（The introducing port 7 and export mouth 8 in filter portion 4）Arrange In a straight line, the straight line is parallel with the central shaft of the row of two row configurations.Moreover, link multiple pipelines 6 of multiple filters 2 For parallel configuration, turn into branch line, be made up of respectively single ester moulding pipe.Moreover, multiple branch lines are shown in Fig. 2 Same shape branch line 6.Because the branch line 6 is that top is inserted into mode into joining line, so can pass through Once-through operation is simply plugged into the introducing port 7 in filter portion 4 or export mouth 8 enters joining line.In addition, the filter of multiple filters 2 The shape in portion 4 also turns into same shape.Due to being filter 2 as described above, the configuration in filter portion 4, shape, pipeline structure, So branch line 6 is simple shape, and connect without multiple pipelines such as usually used flexible pipes or T-shaped pipe joint, elbow This numerous part, piping operations are simple, simple.Further, since branch line 6 is ester moulding pipe and cheap, and Necessary branch line 6 is one kind of identical shape, and this make it that the ester moulding metal pattern of branch line 6 is also one Kind, contribute to further cheap manufacture, also do not produce the mistake of assembling.The one kind for being shaped as same shape in filter portion 4 also has There is same effect.On the other hand, also can be in the parallel configuration shown in Fig. 1 certainly, it is logical to have used to make branch line Normal flexible pipe and the form of the pipe joint of T-shaped pipe joint or elbow, this is also included in the present invention.So, part Start with easily, the advantages of versatility is excellent can be obtained.

In the water purifier 1 of Fig. 1 embodiment, filter 2 is the structure of four, but as long as being to include parallel configuration At least two（Two pieces）Filter, configuration three（Three）The water purifier of the structure of filter above, then can realize two The interconnected parallel configuration of row, can also obtain above-mentioned effect, effect.

Fig. 8 using the diagrammatic top view in the connecting line path of the parallel configuration of filter represent Fig. 1 embodiment and Variant embodiment of the invention beyond it.In fig. 8, circle represents filter（And filter portion）, the straight line between circle Represent pipeline.

In addition, the parallel configuration of the filter of the embodiments of the present invention example different from Fig. 8 is represented in Fig. 9, Figure 10 The diagrammatic top view in connecting line path.On the other hand, Figure 11 is to be not belonging to the present invention（The part on parallel configuration）'s The diagrammatic top view in the filter connecting line path in form example.In Fig. 9, Figure 10, Tu11Zhong, circle and straight line have and figure 8 identicals are looked like.

In the embodiment of Fig. 8 any figure, the aggregate value of the angle of bend in the connecting line path of parallel configuration is equal Non- 180 degree（Less than 200 degree）, number of bends is twice, and connecting line path becomes the path of same shape.Although not Diagram, but for example also can be to make angle of bend different in two connecting line paths of parallel configuration, make this two connections The form that the shape in pipeline path differs.

Fig. 8（A）Equivalent to Fig. 1（B）.Fig. 8（B）Whether it is interconnected but two row parallel configurations example.Fig. 8 （C）It is the example that two groups of parallel configurations staggeredly be present.It is curved in connecting line path in respective one group of parallel configuration The aggregate value of bent angle is less than 200 degree, and number of bends is twice.Fig. 8（D）It is in Fig. 8（B）Variation in, it is in parallel The filter of configuration arranges as lateral attitude, is compact in the horizontal, but in figure on longitudinal direction, due to being Fig. 8（A）~figure 8（C）The distance between the central shaft of each row being set in two row of two row configuration is smaller than the outside dimension of filter, so being Compact.

In Fig. 8（A）~Fig. 8（D）In, the respective entrance and exit of filter arranges in a straight line, the straight line and two It is parallel to arrange the central shaft of the row of configuration, while multiple branch lines of parallel configuration are the branch lines of same shape, filter portion Shape be also identical shape.Therefore, branch line, filter portion are one kind, help inexpensively to manufacture, will not also produce assembling Mistake.

In Fig. 8（E）~Fig. 8（G）In, filter portion is not identical shape, has two kinds of filter portions.In two kinds, filter The branch in portion itself including parallel configuration, carry out pipeline path bending species filter portion.By using this filter portion, With Fig. 8（A）Compare, realize greater compactness of configuration in the horizontal.

Especially, Fig. 8（F）And Fig. 8（G）It is the example of parallel configuration staggeredly, due to each in two row of two row configurations The distance between central shaft of row is not only set to smaller than the outside dimension of filter, is also set in the horizontal through filter Distance between the vertical line towards central shaft of each row at center is smaller than the outside dimension of filter, so in longitudinal direction and horizontal stroke It is upwards compact.Further, since be interconnected, thus be it is compact,（Longitudinal direction, the depth direction i.e. as water purifier 's）The filter of 2nd row is come between the filter of the 1st row, so being easy to choose from the 1st row side（Water purifier face side）Rise The 2nd row filter, its replacing, maintenance when facilitate.

In Fig. 8（E）And Fig. 8（F）In, the pipeline between filter is not identical shape, has two kinds of pipelines.The opposing party Face, in Fig. 8（G）In, multiple branch lines of parallel configuration are the branch lines of same shape.

Fig. 9（A）It is in Fig. 8（A）In respective angle of bend be 45 degree of form, the aggregate value of angle of bend is 90 degree. In the Fig. 9（A）In, because the aggregate value of angle of bend compares Fig. 8（A）It is small, so the pressure loss in bending can further drop It is low.But in order to avoid Fig. 8 is compared in the mutual interference of filter, the pipeline path of straight line portion（A）It is long, the horizontal stroke as water purifier Also lengthened therewith to length.

Above-mentioned form be pipeline each other by defined angle link in the form of, even if being the bending for being bent into circular arc Form can also carry out same definition.For example, Fig. 9（B）It is in Fig. 8（A）In be bent into circular arc bending form.Due to pipe Road is not to be linked with defined angle each other, but depicts circular arc, so the definition of angle of bend is difficult.Therefore, obtain Towards the mutual intersecting angle of tangent line of circular arc at the two-end-point of circular arc, the intersecting angle is considered as angle of bend.I.e., in Fig. 9 （B）Form in, due at the two-end-point of circular arc towards circular arc the mutual intersecting angle of tangent line be 90 degree, so one group of company The aggregate value of angle of bend in adapter road path turns into 180 degree twice because angle of bend has for 90 degree of bending.Curved In form of the song for the bending of circular arc, by obtaining angle as described above, it can obtain in one group of connecting line path The aggregate value of angle of bend.

In embodiment in Figure 10 any figure, the aggregate value of the angle of bend in the connecting line path of parallel configuration For less than 200 degree, and connecting line path becomes the path of same shape.Moreover, multiple branch lines of parallel configuration It is the branch line of same shape, the shape in filter portion is also identical shape.

Figure 10（A）, Figure 10（B）It is that filter is not that two row configure and are respectively the configuration of 1 row, the embodiment of 3 row configurations. Any embodiment is that number of bends is four times, but small to 45 degree of angle of bend, and the aggregate value of angle of bend is 180 degree, energy Enough reduce the pressure loss as connecting line path.Figure 10（A）Suitable for making water purifier depth（The longitudinal direction of figure）Compact dimensions Situation, in addition, in Figure 10（B）In, in beautiful balanced configuration and it can make to use in the case that lateral dimension is compact.

In above-mentioned Fig. 8~Figure 10, due to illustrating embodiments of the present invention example using diagrammatic top view, so being Premised on the bending in connecting line path is in its plane, even if bending is directed towards outside plane（Above-below direction）It is curved Song, as long as the aggregate value of its angle of bend is 200 degree, then it is also included in the present invention.Especially, Figure 10 of 1 row configuration（A）'s Bending can also be out-of-plane upper direction, as long as this form, then can make water purifier depth（The longitudinal direction of figure）Size is more It is compact.

On the other hand, it is curved in the connecting line path of parallel configuration in the Figure 11 represented as comparative example example Bent angle is 90 degree, and number of bends is four times, and the aggregate value of angle of bend is 360 degree, has exceeded 200 degree.Therefore, the connecting tube The pressure loss in road path is big.（For in passing, in the water purifier of patent document 1, with similar to Figure 11（A）Form simultaneously In the connecting line path for joining configuration, outside the plane orthogonal with the axial direction of column-like filter（Lower direction）With 90 degree of five times Bending, its aggregate value be 450, it is different from the present invention）.

In addition, in the present invention in the invention section beyond the invention of parallel configuration, the configuration of multiple filters, tying Structure is simultaneously not only as described above, by the tap water quality of its region as object or necessary flow etc., such as Can be changing into four be full arranged in series structure, the conjunction of the angle of bend in one group of connecting line path of parallel configuration The structure of evaluation more than 200 degree etc..

, pair then and the filter portion 4 of filter 2 is formed and the relevant construction of combination of filter cylinder 5, structure illustrate.Together When filter 2 is also illustrated to fixed construction on installing plate 3, structure.

In the water purifier or filter of water purifier that are used in general family, in order to easily carry out the replacing of filter cylinder, Designing and used can be in the various construction for the filter portion handling filter cylinder being connected with tap water pipe line.Wherein, card is typically passed through The mechanism of the rotation such as mouth mechanism or screw threads for fastening mechanism carries out filter cylinder to the handling in filter portion.

In addition, the water purifier used in general family, being in particular arranged at the kitchen mo(u)ld bottom half water purification that the bottom of tank uses In device etc., in order to be arranged on water purifier on the wall of the receiving portion of tank bottom, usually the filter of water purifier is fixed On a mounting board, the installing plate is arranged on the wall of receiving portion.Filter is typically to be made up of filter portion and filter cylinder, is filtered Device to the fixation on installing plate is carried out by the way that filter portion is fixed on installing plate mostly.

For example, in the Japanese Laid-Open 2012-143709 public affairs as patent document 1, filter portion is to installing plate（Support Frame）On fixation be that fastening by carrying out more screws from the dorsal part of installing plate is carried out.But filter head positioning is carried Put in the correct position of installing plate, and carry out more screw fastenings from dorsal part to need instrument, exist and take asking for complicated operation Topic.Even the problem of big be present especially in the water purifier with multiple filters.Therefore, in view of this problem, there is provided one Water purifier of the kind with the filter being made up of filter portion and filter cylinder, easily filter portion can be fixed on to wall etc. is upper and pacified It is meaningful on the installing plate of dress.

Fig. 3 is the accompanying drawing relevant with the filter portion 4 in one embodiment of the present invention, filter cylinder 5 and installing plate 3, Fig. 3 （A）It is its longitudinal sectional view, Fig. 3（B）It is its front view, Fig. 3（C）It is its transverse sectional view.In addition, in Fig. 3（A）In, in order to Conveniently illustrate, the circumferential locations of following described bayonet mechanism are deviateed original and showed in the figure.

As shown in figure 3, filter cylinder 5 is rotated by bayonet mechanism, detachably it is installed in filter portion 4 and combines, forms Filter 2.In more detail, at least two bayonet sockets are provided with the periphery of the lid 12 on the top for forming the filter cylinder 4 that profile is column Outside cylindrical portion by filter portion 4 is axially inserted into reference to the upper part of convex portion 19, including the lid 12 of bayonet socket combination convex portion 19 36 its inner space 38 distinguished, bayonet socket combination convex portion 19 is relative to the bayonet socket knot being located in the outside cylindrical portion 36 in filter portion 4 Close recess 39 to engage, rotate, complete the combination of bayonet mechanism.In the case where removing filter cylinder 5, by combine when it is opposite Direction rotates and carried out.So, because filter cylinder 5 is carried out to the handling in filter portion 4 by bayonet mechanism, so the operation letter of handling Just, easily.

At least one the 1st convex portion 41 (engaging position) for being capable of elastic displacement is provided with filter portion 4, in filter cylinder 5（Lid 12）Outer surface is provided with least one 2nd convex portion 24（Engaged position）, it is configured to as filter cylinder 5 is in order to in filter portion 4 Installing and rotates, completed stage at it, progress elastic displacement in the 1st convex portion 41 crosses the 2nd convex portion 24, the 1st convex portion 41 and the 2nd convex Portion 24 engages.Crossed by this（Engaging）, obtain the installing sense of the filter cylinder 5 of bayonet mechanism progress.In the embodiment shown in Fig. 3 In, the 1st convex portion 41 is by being located at the breach 42 of the lower, outer perimeter edge in filter portion 4 and from the peripherally disposed slit 43 of breach 42 Formed, turn into circumferentially extending shape.Certainly, the shape of the 1st convex portion is not limited to that, Fig. 4 preferably as be described hereinafter Shown is square frustum like that（Or the frustum of a cone, square column, cylinder, hemisphere）The shape of shape.The shape of 2nd convex portion is square column in figure 3 Shape, but also can be the shape same with the 1st convex portion.In addition, the set location for the 1st convex portion being located in filter portion can not also It is lower, outer perimeter edge, and is, for example, the inner peripheral surface of outside cylindrical portion 36.Now, the position of the 2nd convex portion is also set at and the 1st certainly The corresponding position in convex portion.

So, the part being not provided with beyond the part of installing, only passes through two parts（It is the He of filter cylinder 5 in this case Filter portion 4）I.e. being capable of installing sense that is easy, inexpensively reaching filter cylinder 5.In addition, being felt according to its installing, user can either be reliable Ground knows that installing is completed, and can not also make a mistake（It is water-tight）Reliably installed on ground.And then it is in filter in the 1st convex portion 41 In the case of the lower, outer perimeter on head, due to user can identify this case, so can with installing sense together with by regarding Feel and more reliably confirm that installing is completed.

In order to more reliably confirm filter cylinder to the installing completion in filter portion, the preferably mark on filter cylinder outer surface by vision Know（Both can be above-mentioned the 2nd convex portion or other projections mark or printing mark etc.）, and it is located at filter portion It is readily seen that place mean installing complete mark（The word or pattern of the formation such as printing or marking）It is configured to filtering Position when wound packages sets completion is compared as the circumferential locations that filter cylinder rotates（It is or consistent）.

Meanwhile similarly the place the being readily seen that setting in filter portion means that filter cylinder is removed（Or start to install）'s Mark（The word or pattern of the formation such as printing or marking）, it is preferably arranged to remove in filter cylinder and completes（Or start to install）When Position, it is compared as circumferential locations with the mark on foregoing filter cylinder outside（It is or consistent）.In such manner, it is possible to by regarding Feel that the dismounting for reliably confirming filter cylinder is completed（Or start to install）.

In the embodiment of fig. 3, the 1st convex portion 41 can elastic displacement, but also can be to enable the 2nd convex portion on the contrary The variant embodiment or both sides' elastic displacement of elastic displacement.As long as that is, engaging position and/or by card Close position can elastic displacement, with filter cylinder 5 in order to be rotated to the installing in filter portion 4, engaging position and engaged position Engaging, it is capable of the elastic displacement state change at the position of elastic displacement, so as to obtain the knot of the installing sense of the filter cylinder of bayonet mechanism Structure.Therefore, the form that position and engaged position may not be the 1st convex portion and the 2nd convex portion is engaged, but convex portion and recessed Portion（Or recess and convex portion）Variant embodiment.In the case where being the form of the convex portion and recess, with filter cylinder 5 in order to Install and rotate on to filter portion 4, convex portion engages with recess, be chimeric, as convex portion and/or the portion for being capable of elastic displacement of recess The elastic displacement state change of position, obtains the installing sense of filter cylinder caused by bayonet mechanism.

As illustrated in figure 1, in water purifier 1, the respectively different multiple filters of filter material inside filter cylinder 5 are contained in 2 are fixed on installing plate 3 and use.In multiple filters 2 of the water purifier 1, there is provided the 1st of above-mentioned bayonet mechanism installing sense The position of the convex portion 24 of convex portion 41 and the 2nd and/or shape are not both accordingly preferable shape with the filter material being contained in inside filter cylinder 5 State.For example, can be the filter material of above-below direction position and the receiving of paired the 1st convex portion 41 and the 2nd convex portion 24 accordingly not Same form.In addition, for example can be 1st convex portion and round and smooth 2nd convex portion of the end shape for acute angle relative to certain filter material Combination, then on the contrary, the shape of the combination of round and smooth the 1st convex portion of end shape and the 2nd convex portion of acute angle in certain other filter material State.If this shape, then can be correct acute angle convex portion and round and smooth convex portion combination beyond acute angle convex portion that This combination can not be crossed mutually（Engaging）, in addition, round and smooth convex portion combination with one another then it is mutual cross too easily and Installing sense can not be accessed.

If becoming above-mentioned form, even if the wrong filter cylinder different from the filter cylinder that should be installed originally is installed in Filter portion, the 1st convex portion and the position of the 2nd convex portion and/or shape also will not be mutually corresponding well（Can not rightly it engage）, Installing sense caused by bayonet mechanism can not be accessed, or the 1st convex portion and the 2nd convex portion collide with each other, it is impossible to physically complete The combination carried out into bayonet mechanism.According to these phenomenons, user can feel that the filter cylinder of installing is wrong.I.e., can prevent The mistake installing of filter cylinder with different functions respectively, the installing of the filter cylinder reliably correctly selected.

So, in the 1st convex portion 41 for making the installing sense of offer bayonet mechanism and position and/or shape and the appearance of the 2nd convex portion 24 Be contained in filter material inside filter cylinder 5 accordingly different embodiment turn into exist it is corresponding from different multiple filter species Multiple filter portions and filter cylinder shell, make multiple metal patterns as resin forming product the state of affairs.Therefore, filter portion and filter The shell itself of cylinder is one kind, makes to split the 1st convex portion and the 2nd convex portion, is subsequently made by welding or screw fixation etc. Industry, the embodiment of the article of other position and/or the other shape of installation is correspondingly mounted to due to making with filter species Valency it is cheap and more preferably.

Certainly, this with the water purifier of multiple different types of filter cylinders, the mistake installing of filter cylinder prevents from taking Certainly in for obtain above-mentioned bayonet mechanism installing sense the 1st convex portion the 2nd this construction in convex portion, and set other key construct into OK, but as described above, dual-purpose obtain bayonet mechanism installing sense construction carry out by mistake install prevent from succinct, cheap viewpoint Consideration is excellent.

Described dual-purpose obtains the mistake dress installed the construction felt and carry out multiple different types of filter cylinders of bayonet mechanism at present The mechanism to set up defences only can be similarly applicable in the variant embodiment of above-mentioned convex portion and recess.

In figure 3, when filter cylinder 5 is attached in filter portion 4, by configuring the outer peripheral face in lid 12, and filter portion 4 is outer Two seal members between the inner peripheral surface of side cylindrical portion 36 and inner side cylindrical portion 37（1st seal member 20 and the 2nd sealing Part 21）, liquid-tight sealed knot closes between filter cylinder 5 and filter portion 4, it is ensured that as raw water（Upstream）And water purification（Downstream）Stream Hydraulic tightness.

In the raw water that the introducing port 7 with filter portion 4 connects（Upstream）Circuit portion and as the top inside filter 4 Part be provided with valve 31.The valve 31 is by generally cylindrical（Top is tubular）Valve body 32, valve body 32 is exerted a force downstream Spring 33, and the valve seal member 34 being installed on valve body 31 are formed.Valve body 31 is fastened on filter portion 4 with its top cylindrical portion Form in the projection of inside top surface is kept.

When not installing filter cylinder 5 in filter portion 4, valve seal member 34 by the elastic force of spring 33 to stream hole peripheral push and Abut, the stream hole is closed, valve 31 turns into closed mode.On the other hand, when having installed filter cylinder 5 in filter portion 4, due to position Abutted in the outer surface tip portion of the outlet cap carrier 18 at the center of the lid 4 of filter cylinder 5 with valve body, overcome the elasticity of spring 33 Valve body 32 is pushed away in power, stream is opened, so valve 31 turns into open mode.The mechanism of valve 31 more than, when installing filter cylinder 5 Can reliably water flowing, further, since valve 31 closes stream when not installing filter cylinder 5, so the installing in filter cylinder 5 is bad or filter When 5 replacement operations of cylinder, the failure of running water ejection can be prevented.

It can be seen from Fig. 3, it is attached in filter cylinder 5 in filter portion 4, when valve 31 becomes open mode, running water is from filter The introducing port 7 in portion 4 flows into, by the valve 31 of opening successively with the entrance 22 of filter cylinder 5, filter material 16, the central stream for exporting cap 14, Cap carrier 18, the sequential flowing of outlet 23 are exported, is led between the outside cylindrical portion 36 and inner side cylindrical portion 37 of filtration head 4 Stream is to export mouth 8 and flows out.

Description is illustrated to construction fixed on installing plate 3, structure to the filter 2 in Fig. 3 embodiment.

Filter 2 is fixed on installing plate 3 in the form of filter portion 4 loads, is fixed on installing plate 3.Set on installing plate 3 There is opening 51, at least one breach 52 is provided with its periphery（The engaged part of projection）.On the other hand, in filter portion 4（Outside Cylindrical portion 36）Bottom is formed with the projection 44 for being capable of elastic displacement.In the context of fig. 3, projection 44 can be to radially inner side Displacement.It is fewer than breach 52 but it is also possible to be quantity that projection 44 is preferably provided with the quantity corresponding with breach 52.Filter portion 4 is carried Put in the assigned position of installing plate 3, by being pushed from top, projection 44 inserts breach 52 and engages and be fixed.In projection 44 and breach 52 have it is multiple in the case of, due to projection 44 can elastic displacement, so can once insert, engage.Certainly, dash forward 44 amounts for being capable of elastic displacement are played to be set to more than projection 44 and the size of the both sides of breach 52, the fabrication error of position.

By the fixing means, filter 4 easily can be fixed on peace without using other part such as screw or instrument In loading board 3.In figure 3, because the engaged part of projection is the breach 52 of the periphery of opening 51, so the card by projection 44 Close, filter portion 4 is diametrically fixed also relative to installing plate 3.

In addition, using above-mentioned fixture construction, structure, with pipeline 6 by the phase of filter 4 of multiple filters 2 shown in Fig. 1 After mutually linking, once the multiple filter portions 4 linked can be fixed on installing plate 3, the assembling manufacturing of water purifier 1 holds very much Easily.

So fixed filter portion 4 is removed from installing plate 3, if will artificially be capable of the projection 44 of elastic displacement to Direction of displacement, which pushes, makes its deformation, and with it is fixed when it is on the contrary that filter portion 4 is mobile from installing plate 3 to upper direction and pull out Go out, i.e., can be removed.
