In addition, in order to make washings reliably flow into into water portion 55, being provided with rectification part 31c at the lower surface of the rear surface 31b of water jacket cover 31, being provided with rectifying component 37b at recirculated water cover 30.Packing ring 59 is possessed at the lower surface of rectification part 31c.In addition, packing ring 60 is provided with at the inner surface entering the recirculated water cover 30 of the downside in water portion 55 close to base plate 52.If at recirculated water cover hookup wire bits filter 38, then lower surface and the end face of sidewall 51c, the upper surface of rectifying component 37b of rectification part 31c and the upper surface that covers 53 abut, and the end face of sidewall 51b abuts with the end face of rectifying component 37b.Thereby, it is possible to by flow into from recirculated water entrance 33 washings of the circulation waterway 37c of recirculated water cover 30 roughly all guide to line bits filter 38 enter water portion 55.In addition, make the jump of the part of abutting minimum, and the resistance of flowing can not be produced or hook line bits.

Exist near the leading edge of the substantial middle of Water spray nozzle 34 at the left and right directions of water jacket cover 31, the rear surface 31b at water jacket cover 31, be positioned at the side rearward, center of washing and dewatering groove 9.Water spray nozzle 34 comprises: cylindric spin chamber 34a; Be located at the entrance 34b of the peripheral wall surfaces of spin chamber 34a; Be positioned at bottom surface central authorities and the outlet 34c of the circle of upper shed in the vertical direction; And the basifacial substantially rectangular outlet 34d of the perisporium being located at spin chamber 34a.At least one wall of entrance 34b is connected with the peripheral wall surfaces of spin chamber 34a in a substantially tangential direction.Outlet 34c upper shed in the vertical direction.

If circulating pump 16 operates, washings then in water jacket 10 flow to the top of water jacket 10 by circulation pipe 17 from the water-through and ventilating mouth 10b being located at outer slot bottom, the circulation waterway 37a of recirculated water cover 30 is entered from the recirculated water entrance 33 of water jacket cover 31, utilize line to consider filter 38 to be worth doing and remove line bits, and washings flow into (arrow with reference to Fig. 5, Fig. 7) in washing and dewatering groove 9 by circulation waterway 37 from Water spray nozzle 34.

The flowing of the washings in recirculated water cover 30 is described in detail.Washings from circulation waterway 37a enter line bits filter 38 enter water portion 55(arrow 61).The flow path area entering water portion 55 becomes the shape reduced, thus the flow velocity of washings enters in spin chamber 51 with increasing, and becomes the rotary current (arrow 62) along peripheral wall surfaces 51f.Because the line bits contained in washings are lighter than water, thus the substantially central portion of line bits due to rotary current substantially in spin chamber 51 is turned round while be accumulated into cylindric.Washings flow out (arrow 62a, 63,64) from reticular filter 51a, 52a, the 53a being located at line bits filter 38 to circulation waterway 37.Now, residual line bits are removed, and remain on reticular filter surface.In general line bits filter, the flow direction of washings is substantially vertical with filtering surface, and at filtering surface attached wire bits, the effect of the line bits burden filter of accumulation, thus accumulate line bits always.Therefore, increase the pressure loss of stream, and reduce the circular flow of washings.But in the present embodiment, washings flow pivotally along reticular filter, thus line bits the attachment state on reticular filter surface is died down.Therefore, if the line bits of mesh filter house increase, then can be divested simply by the fluid force of washings, and utilize the effect of swirling flow to concentrate on the central portion of spin chamber 51.Like this, reticular filter automatically cleans, thus can not lodge in reticular filter and block the situation of reticular filter by wired bits, roughly can remain constant by the circular flow of washings.In addition, owing to not needing greatly to need above by the change of reticular filter area, thus the miniaturized aspect of online bits filter 38 is also effective.For the line bits as above gathered, if the circulation of washings stops, then become dumpling shape in the substantially central portion of base plate 52.Therefore, when removing line bits filter, pull down line bits filter 38, open lid 53 and line considered to be worth doing filter 38 and be inverted (make base plate 52 become upside), knock gently, then line bits can fall simply.Therefore, without the direct contact wire bits of hand, and the removing of line bits filter 38 can be carried out simply.In addition, due to the roughly planar of reticular filter and the shape of cylinder planar, some dotted line bits being attached to reticular filter also can be brushed gently with brush etc. and easily remove.

In the present embodiment, the peripheral wall surfaces 51d not near spin chamber entrance, base plate 52c, lid 53e arrange opening portion.This is as rear explanation, owing to making, line bits filter is small-sized, flattening, so the length entering water portion 55 can not be very long, thus the washings entering the spin chamber 51 of line bits filter can not flow out from reticular filter immediately, and then can efficiently and reliably generation rotary current spin chamber 51 in.

In addition, in the structure of the present embodiment, as shown in figure 11, line bits filter 38 is provided with in the position of one deck lower than circulation waterway 37c.This is to flow washings from the recirculated water entrance 33 of the upper surface being positioned at water jacket cover 31 to the line bits filter 38 of lower surface or Water spray nozzle 34 being located at water jacket cover 31.Therefore, because the washings entered into water portion 55 have speed downward, thus the base plate 52c near the inflow part of spin chamber 51 does not arrange opening portion.This is due to following reason, if namely aqueous phase has larger flows at angles for reticular filter, be then difficult to utilize fluid force to remove line bits, thus reticular filter easily blocks.Therefore, the bottom parts 52c not near inflow part arranges opening, in the face that this part makes the flowing of water do one's utmost along reticular filter 52a.In addition, structure aspect, when entering the washings in spin chamber and flowing into relative to the angled mode of cylindrical direction tool with flow direction, in order to carry out rectification to flowing, arranges wall near the entrance of spin chamber.That is, opening portion (mesh filter house 51a) is not set.If size has enough and to spare certainly, then owing to fully guaranteeing the length into water portion 55, thus do not need to carry out above-mentioned countermeasure.

In line bits filter 38 described above, the mode of the motion of the clothing in the washing and dewatering groove 9 during not hinder washing or drying suppresses the height of recirculated water cover 30, thus realizes small-sized, the flattening of line bits filter 38.Therefore, in order to ensure the flow of washings, the peripheral wall surfaces 51d of online bits filter, base plate 52, lid 53 3 faces arrange opening portion (reticular filter), increase filter area.

But, when the size of online bits filter has an enough and to spare, do not need to arrange reticular filter in whole three faces.In this case, opening portion is set at sidewall, the little opening portion being used for draining is set at base plate 52 relatively good.This is due to following reason, namely, be attached to sidewall reticular filter line bits the most easily removed by the fluid force of rotary current.Further, because minimizing bonding, welding etc. arrange the position of reticular filter, thus can cut down finished cost.

In addition, base plate 52 is formed as the low stamp box shape of central part, arranges the opening portion (reticular filter) being used for draining better bottom it.After the circulation of washings stops, draining can be carried out from the line bits of trapping efficiently, thus can remove more like a cork.

The washings of circulation waterway 37 enter in Water spray nozzle 34 (arrow 65) from entrance 34b.Further, the peripheral wall surfaces along spin chamber 34a flows in Water spray nozzle 34, and again becomes rotary current (arrow 66).Further, discharge in washing and dewatering groove 9 from the outlet 34c of bottom surface.Due to the pivotal centrifugal force of water effect in spin chamber 34a, thus as shown in the arrow 67 of Fig. 2, turn round the cone shape film-form becoming and expand from the water that outlet 34c discharges downwards, and roughly equably washings is sprayed.Therefore, the water yield make washings throughout washings, even if also can realize high clean power less.

If the running of circulating pump 16 stops, then the circulation of washings stops certainly, but is full of washings in circulation pipe 17, recirculated water cover 30, and these washings pass through circulation pipe 17 at a heat to adverse current in water jacket 10 because of gravity.Therefore, if circulating pump 16 stops suddenly, then the line bits that line bits filter 38 traps also return in the circulating pump 16 below water jacket or in the inside and outside groove 10 of circulation pipe 17 together with washings.This is a kind of back washing effect, does not need to remove the line bits in line bits filter.But line bits are bits filter interior one-tenth block online, thus there is the worry flowing in scupper hose 24 when blocking circulation pipe, draining and block draining catcher.

Therefore, when circulating pump 16 stops, the rotating speed of circulating pump declines, and becomes identical or than low height the rotating speed of the height of considering the lower surface of filter 38 with line to be worth doing and keeps 5 ~ 10 seconds, stop afterwards with the discharge water-head height of circulating pump.Like this, suck air while make the washings slowly adverse current in recirculated water cover 30 from Water spray nozzle outlet 34c, thus the line bits that can prevent line from considering to be worth doing in filter 38 move to circulation waterway 37c effluent together with washings.
