As depicted in figs. 1 and 2, the backboard 2 of washing machine 1 is provided with feed water valve 3.The water supply that feed water valve 3 has on the outer supply equipment of the machine of being attached at is taken into a mouthful 3a (Fig. 2), and its water supply is taken into the structure example of mouthful 3a as being the water supply hose that can connect from water pipe.And in the inside of the backboard 2 that is covered by panel cover 7 to be opened/closed (Fig. 1), the impurities removing unit 4 of removing the impurity in anhydrating is connected with feed water valve 3, is communicated to water supply via this impurities removing unit 4 and is taken into feed water inlet 5 on mouthful 3a towards cylindric washer 6 openings.Be taken into the water that mouthful 3a is taken into from water supply and flow along the direction of arrow as illustrated in fig. 2,5 flow out from the feed water inlet, supply water to cylindric washer 6 by impurities removing unit 4 and connecting piece 5a.

As mentioned above, being configured in supplies water is taken into impurities removing unit 4 between mouthful 3a and the feed water inlet 5 shown in Fig. 3 A, Fig. 3 B, keeps tube 33, filter 34 etc. to constitute by housing 36, filter.Housing 36 becomes roughly cylindric for the part of the shell of formation impurities removing unit 4.Its shape is not limited in cylindric or roughly cylindric so long as be applicable to the shape of filter 34 grades and get final product.For example, also can be that the cross section is tubulars such as ellipse, polygon or tubular roughly.And, be formed with on housing 36 that being communicated to supplies water and be taken into the inflow entrance 31 of mouthful 3a, and be communicated to flow export 37 on the feed water inlet 5 via connecting piece 5a (Fig. 2).The peristome of an end roughly cylindraceous forms as inflow entrance 31, and the peristome of the other end can be opened by lid 39 loading and unloading freely via liner 38.And the structure of flow export 37 is from the outstanding shape of periphery cylindraceous roughly, can be connected with connecting piece 5a (Fig. 2).

The filter that disposes the round-ended cylinder shape in the inboard of housing 36 keeps tube 33.The shape that filter keeps tube 33 is not limited in cylindric or roughly cylindric also so long as be applicable to the shape of filter 34 grades and get final product.For example, can be that the cross section is tubulars such as ellipse, polygon or tubular roughly.It is that an end is communicated with inflow entrance 31 at peristome 33c that this filter keeps tube 33, and the other end is with respect to airtight from the water route of inflow entrance 31.So, on the periphery of filter maintenance tube 33, be formed with a plurality of opening 33h that are communicated with flow export 37.

The filter cylindraceous 34 that the nonwoven fabric that keeps the inboard of tube 33 to dispose polyester at filter constitutes.Filter 34 is for by filtering the dedusting mechanism of the impurity (for example metal species such as ferrous components) that removes anhydrating to the water that is taken into from inflow entrance 31.As the material of filter 34, except nonwoven fabric, can list filter membrane (hollow fiber film, flat film etc.), active carbon etc.That is,, adopt nonwoven fabric as filter 34, filter membrane (hollow fiber film, flat film), the filter of at least a formation in the active carbon gets final product.By this filter 34 is used for removing of water impurity, in impurities removing unit 4, can reduce the resistance of water by the area that impurity is removed in increase.

In filter maintenance tube 33, on the one end, be formed with fulcrum 33a, on the other end, be formed with fulcrum 33b by 39 supportings of lid by 36 supportings of housing.In fulcrum 33b one side, between filter keeps tube 33 and covers 39, elastomers 40 such as spring, rubber are installed.As shown in Figure 3A, because filter keeps tube 33 application of forces because of elastomer 40 to be connected on the inner surface of housing 36 in fulcrum 33a one side pressure, the water that is taken into from inflow entrance 31 all keeps in the tube 33 from peristome 33c inflow filter.In addition,, then also can replace elastomer 40, for example keep tube 33 from covering 39 the outside or the outside pushing filter of housing 36 so long as filter is kept the structure of tube 33 application of forces with the power of regulation.

And, in inflow entrance 31 1 sides of impurities removing unit 4, dispose demonstration ring 32 as the flow quantity detection mechanism that detects the water yield that flows into.Be formed with blade 32a in the inboard that shows ring 32, blade 32a can rotate freely ground fulcrum 33a installation relatively.Therefore, when bearing current, show that ring 32 is the center rotation with fulcrum 33a by blade 32a.

Keeping at filter 34 under the situation of suitable filtering function, as shown in Figure 3A, the water that is taken into from inflow entrance 31 promotes blade 32a, makes to show ring 32 rotations, keep in the tube 33 by peristome 33c inflow filter, see through filter 34 from the part of its opening 33h.At this moment, the impurity that is filtered in the water because of water is removed.The water that has seen through filter 34 is via the gap between filter maintenance tube 33 and the housing 36, by flow export 17 5 outflows from the feed water inlet.

For example, the zone of poor water quality of containing ferrous components in volume is under the situation that washing machine 1 supplies water, and the nonwoven fabric that contained iron colloid can not constitute by the mesh with prescribed level in the water is filtered device 34 and stops.When long-time supply volume contains the water of ferrous components, owing to impurity is deposited on the inwall of filter 34, so must suitably carry out the cleaning or the replacing of filter 34.The folding and unfolding as illustrated in fig. 1 of this impurities removing unit 4 is covered by the panel cover 7 that can dispose in backboard 2 with opening and closing.And shown in Fig. 3 A, Fig. 3 B, housing 36 and lid 39 can load and unload.Therefore, cover 39, then can take out and be installed in the filter 34 that filter keeps 33 inboard, clean or change if under the state that panel cover 7 is unloaded from backboard 2, take off from housing 36.

When because of the obstruction aggravation of the accumulation filter 34 of above-mentioned impurity, filter keeps the interior pressure of tube 33 to uprise, and the output that is taken into mouthful 3a from water supply reduces.And, when output reduces, show that the rotary speed of ring 32 also reduces.That is, show that ring 32 works as detecting the testing agency that has produced the hydraulic pressure more than the regulation in the inside of impurities removing unit 4.Therefore, by monitoring the rotary speed that shows ring 32, can confirm the blocked state of filter 34.And, if set in advance demonstration such as clause apperance in appearance, then can carry out this affirmation easily what show ring 32.

And; use if under the situation of the obstruction of filter 34 aggravation, continue; then when flowing of water worsened terrifically; on the part of lid 39, will apply big hydraulic pressure; being arranged on that filter keeps tube 33 and cover elastomer 40 (spring, rubber etc.) between 39 is to be used for parts that it is protected; produced in inside under the situation of the above hydraulic pressure of regulation, worked as the mechanism of decompressor of alleviation its hydraulic pressure because of the obstruction impurities removing unit 4 of filter 34.That is, when the hydraulic pressure more than the regulation was applied on the filter maintenance tube 33, elastomer 40 was compressed, filter keeps right-hand move of tube 33 in Fig. 3 A, and its result is shown in Fig. 3 B, the crimped status of the left end of filter maintenance tube 33 and the inner surface of housing 36 is disengaged, and gap 33d opens.When gap 33d opens, to open towards the water route of flow export 37, water flows to flow export 37 from gap 33d, alleviates to be applied to the hydraulic pressure that covers on 39 parts.So, can prevent to produce excessive hydraulic pressure in the impurities removing unit 4, prevent the breakage of impurities removing unit 4 in advance.
