Washing and dewatering groove 5 as shown in Figure 2, the limit, upper end of the bowl-shape bottom 5c that makes by limit, lower end and the stainless-steel sheet of body portion 5b cylindraceous that stainless-steel sheet is made combines through spinning and constitutes.Bottom 5c is processed to form stepped through pull and stretch, make its upper edge diameter that combines with body portion 5b bigger than the bottom that embeds lower flow gimbal 8, outside bottom surface is by being enhanced by the fastening ring flange 5d of screw, and the outboard shafts of the dual output shaft 16b of above-mentioned clutch portion 16 combines with this ring flange 5d.In addition, the inner shafts of this dual output shaft 16b passes above-mentioned ring flange 5d and bottom 5c, on its top in conjunction with above-mentioned impeller 7.The rear side of this impeller 7 is provided with centrifuge blade 7a, and this centrifuge blade 7a is surrounding the indoor rotation of washings circulating pump that forms its periphery by minim gap by above-mentioned lower flow gimbal 8.Cycling use of water passage 25 is installed on the internal face of washing and dewatering groove 5 with the state of direction extension up and down, form the aquaporin 25a that yarn captures usefulness, its bottom strides across the narrow that forms on above-mentioned lower flow gimbal 8, outlet place at above-mentioned washings circulation pump chamber offers water inlet, on the outlet of offering in the upper end,, be provided with yarn and reclaim filter screen 26 as showing as Fig. 1.
At the centrifuge blade 7a of the above-mentioned impeller 7 of the indoor rotation of above-mentioned washings circulating pump the indoor washings of this washings circulating pump are pressurizeed its row to above-mentioned water inlet, and the outlet pass 5e by washing and dewatering groove 5 downsides sucks the washings in the water jacket 4.
As shown in Figures 3 and 4, for entering of the embedding that prevents clothing and foreign matter, and reducing leaking of washings circulation pump chamber, the relative gap G in the periphery of impeller 7 and the hollow ring of surrounding this impeller 7 lower flow gimbal 8 on every side between week is preferably narrow as far as possible.This relative gap G is set at about 0.5-1.5mm, and the face of opposite side forms band hierarchic structure.In addition, big variation takes place in expansion and contraction that distortion that must make bending that the above-mentioned relative gap between impeller 7 and the lower flow gimbal 8 can not cause because of the centrifugal force that when running dehydration produces, cause through secular variation and variations in temperature cause, makes relative gap become excessive or disappears.Lower flow gimbal 8 in the present embodiment, in order to reduce the amount of the distortion that bending that centrifugal force causes and secular variation cause, support under the state of this fluid balance ring 8 at the bottom 5c that makes with stainless-steel sheet, by pass a plurality of trip bolts 27 of this diapire from the outside of the diapire of this bottom 5c, the inboard that above-mentioned bottom 5c was drawn in and be fixedly installed on to this fluid balance ring 8, make the diapire face butt of its bottom surface and this bottom 5c, and the side wall inner surfaces butt of its outer peripheral face and this bottom 5c, to suppress crooked and distortion.In addition, in order to reduce the variation of the relative gap that temperature variant expansion and contraction cause, the hollow ring of impeller 7 and lower flow gimbal 8 is shaped with thermal coefficient of expansion material (all using polypropylene) about equally respectively and makes, so that both sides have equal coefficient of thermal expansion.
Be located at the height of upper surface of lower flow gimbal 8 of bottom 5c of washing and dewatering groove 5 and impeller 7 baseplate part 7b upper surface about equally, on the upper surface of the hollow ring of this lower flow gimbal 8, be formed with and improve the raised line 8b that detersive efficiency is used.
The installation of the bottom 5c of 8 pairs of washing and dewatering grooves 5 of lower flow gimbal hinders this installation exercise for fear of body portion 5b, installs before being attached to this body portion 5b on the 5c of this bottom.On the bottom surface of bottom 5c, be formed with locating hole 5g, on lower flow gimbal 8, give prominence to being provided with the alignment pin 8a chimeric with this locating hole 5g.Lower flow gimbal 8 is embedded bottom 5c with the state that its alignment pin 8a embeds above-mentioned locating hole 5g, fastening with trip bolt 27.
The as above washer-drier of structure, because the inner peripheral surface supporting of being arranged to the bottom 5c of the washing and dewatering groove 5 made with stainless-steel sheet constitutes the outer peripheral face of the hollow ring of lower flow gimbal 8, so the distortion that centrifugal force in the time of suppressing the dehydration running and secular variation cause, so can make with the thin thin-wall member of wall.And, because this lower flow gimbal 8 is arranged on to surround its outer peripheral portion with the roughly the same height of impeller 7, to form the position of washings circulation pump chamber at the dorsal part of this impeller 7, so, though this lower flow gimbal 8 is arranged on the inside of washing and dewatering groove 5, has also reduced dwindling of washing capacity.
In addition, as previously mentioned, because the deflection of lower flow gimbal 8 is little and the hollow ring of impeller 7 and this lower flow gimbal 8 is that polypropylene forms with identical materials, so the variable quantity of the relative gap between the two that temperature variant expansion and contraction cause is little.
Have, the raised line 8b that is positioned on the upper side of the lower flow gimbal 8 around the impeller 7 produces drag effect to the washings that is stirred by impeller 8, and washing force is increased again.
Also have because body portion 5b with lower flow gimbal 8 is installed in the 5c of this bottom before bottom 5c combines, make body portion 5b not hinder installation exercise, so installation exercise makes things convenient for.
In addition, made the effect that the end difference of the bottom 5c of pull and stretch processing has this bottom of enhancing 5c rigidity for embedding lower flow gimbal 8.
Again, the outer peripheral face of the hollow ring of lower flow gimbal 8 needn't closely contact with the inner peripheral surface of the bottom 5b of washing and dewatering groove 5, if make the state that embeds relative to each other through minim gap, can obtain same effect.
In addition, because it is littler than the internal diameter (being the internal diameter of this protuberance position when body portion 5b inner surface has protuberance) of body portion 5b to embed the diameter (external diameter of hollow ring) of inner peripheral surface of bottom 5c of hollow ring periphery of above-mentioned lower flow gimbal 8, so under the situation of no top fluid balance ring 6 (or omit or install later on), after body portion 5b and bottom 5c riveted joint combines, also can insert lower flow gimbal 8 and embed bottom 5c and finish setting from the opening part of this body portion 5b.
Below other embodiment of above-mentioned lower flow gimbal 8 are used in explanation.
In Fig. 5, the 28th, with the cavity that wall is separated out, be located at the inside of lower flow gimbal 8, enclose the liquid that not shown salt solution etc. is arranged respectively.
Again, also be provided with this cavity, and do the logical state of phase of helping in the bottom of penstock 25b.
At this, not establish the yarn filter screen at the outlet of aquaporin 25a, but directly be supplied to washing and dewatering groove 5, its form is the sprinkling shape.Again, its height sprays in the position more much lower than specified water level.Specifically be impeller 7 slightly above.
The 30th, be located at end difference all in the lower flow gimbal 8, the end difference 7b combination with being located at impeller 7 peripheries constitutes labyrinth collar, reduces the leakage of cleaning solution from this part.
The 29th, be located at the peripheral part of lower flow gimbal 8 and near the recess the bottom 31, also be the common aquaporin that forms of inwall and bottom by protuberance shown in Figure 6 32 and washing and dewatering groove 5.
As mentioned above, aquaporin 29 is when 8 driving fits of lower flow gimbal being inserted when being embedded in the inner bottom part of washing and dewatering groove, by and the inwall and the gap between the bottom surface of washing and dewatering groove formed, blade 7a links to each other with the back.
Therefore,, only contact with cell wall at protuberance 32 places that are located at peripheral part and bottom when lower flow gimbal 8 being inserted when being embedded in the bottom of washing and dewatering groove 5, thus with whole comparing of contacting, more help assembling.
Again, also can can't help near the periphery of lower flow gimbal 8 and the bottom to form aquaporin 29 with the inwall and the gap between the bottom surface of washing and dewatering groove, and near periphery of lower flow gimbal 8 own and bottom formation aquaporin 29.
In addition, when back blade 7a carried out pump suction action, aquaporin 29 through the downside of diapire face 31, was supplied with cleaning solution the middle body of back blade 7a from the inboard cleaning solution that directly imports of washing and dewatering groove 5.
Fig. 6 is the view along Fig. 5 A-A direction, and 40 among the figure is the walls that form the aquaporin 25a of watering usefulness, is formed with the upper wall surface 41 of cycling use of water passage 25.
Fig. 7 is the stereogram of the aquaporin 25a of watering usefulness, the inlet of the cycling use of water passage 25 that is formed by the sidewall 35 of cycling use of water passage 25 sprays the watering mouth 51 of cleaning solution towards the outlet of back blade 7a opening significantly to washings when having with low water level wash up.The aquaporin 25a of this watering usefulness is formed by synthetic resin, is installed on this inwall at the state on the inwall of washing and dewatering groove 5 with driving fit roughly.
Fig. 8 is under the state of the aquaporin 25a that sheds watering usefulness, the drawing of seeing from the top, 35A is the chimeric wall in the outside of sidewall 35 with the aquaporin 25a of watering usefulness among the figure, the 33rd, form the bottom surface of aquaporin with upper wall surface 41 combinations of the aquaporin 25a of watering usefulness.
Protuberance 32 when bottom fluid balance ring 8 is inlaid in the bottom of washing and dewatering groove 5, forms aquaporin 29 as previously mentioned between the internal face of recess 50 and washing and dewatering groove 5.
In addition, as shown in Figure 9 along shown in the cutaway view of Fig. 8 B-B, this protuberance 32 is also outstanding to the bottom, and also forms aquaporin between the bottom of washing and dewatering groove 5, Figure 10 and Figure 11 show the cutaway view of Fig. 8 C-C, D-D respectively.
On the other hand, the cavity 28 of lower flow gimbal 8 is full Zhou Xiangtong respectively, and in the bottom of cycling use of water passage 25 as shown in Figure 9, cavity 28 dwindles and communicates with the elsewhere.Under the situation of said structure, very dirty but when measuring few clothes washing when carrying out collar, coat-sleeve and so on, put into washings and washing agent and select " collar, coat-sleeve washing procedure " when starting of washing machine again, promptly 23 supply with water by the instruction of not shown control device from the admission port, water level settings is in the position lower than the watering mouth 51 of the aquaporin 25a of watering usefulness.
Simultaneously, drive motors 15 rotations, its power passes to impeller 7 through transmission device.
Impeller 7 rotates, applies mechanicals efforts to washings, carries out " the powerful washing " of washing in low water level.
At this moment, the back blade 7a that is wholely set in the rear side of impeller 7 also rotates simultaneously,, sucks a pump-absorb action by at the dewatering hole 5a on the wall of washing and dewatering groove 5 and between water jacket 4 and washing and dewatering groove 5 from inlet hole 5e.
Because the inlet of the cycling use of water passage 25 relative with the outlet of back blade 7a has enlarged significantly,,, spray cleaning solution to washings from watering mouth 51 through the aquaporin 25a of watering usefulness so can carry out a large amount of pumping up water.
But because this moment, water level settings got very lowly, the number of the dewatering hole 5a of opening is just few under the cleaning solution liquid level, so only use dewatering hole 5a, just can not supply with the corresponding cleaning solution of pump energy-absorbing power with back blade 7a fully.
In order to solve this unfavorable condition, the quantity that increases dewatering hole 5a is good, but this can cause the intensity decreases of washing and dewatering groove, so be restricted, can not unrestrictedly increase the quantity of dewatering hole 5a.
In the present invention, because the aquaporin 29 that forms between the inwall of being located near lower flow gimbal 8 peripheries and the bottom protuberance 32 and washing and dewatering groove 5 also can suck cleaning solution, so can fully supply with cleaning solution with corresponding necessity of pumping capacity of back blade 7a.
Therefore, in washing process, can be sprinkled upon a large amount of cleaning solutions on the washings, because a large amount of sprinklings of this cleaning solution, can promote the dissolving of powder detergent, and make cleaning solution soak into the floating washings of going up liquid level as early as possible, with the effect of " powerful washing " in low water level superposition mutually, increase substantially scourability.
In addition, as the 3rd embodiment, as shown in figure 12, because also can directly supply with cleaning solution from the inboard of washing and dewatering groove 5 to back blade 7a, so many aquaporins, watering road can be set, supply with washings from a plurality of positions more substantial cleaning solution, make its circulation.
B-B shown in Figure 12, C-C, D-D section and second embodiment's is just the same, and its shape is corresponding with Fig. 9, Figure 10, Figure 11 respectively.
Have again, the 4th embodiment is in the device of second, third embodiment, be provided with again as shown in figure 13, water level brings up to the other aquaporin that near the capture yarns the upper flow gimbal 6 are used, at network 49 frame 37 of groove 38 interpolations of its watering mouthfuls 51, accept to flow into cleaning solution in the washing and dewatering groove 5 with this net 49, capture the yarn in this cleaning solution through aquaporin 25a and watering mouthfuls 51.
Figure 14 shows the fifth embodiment of the present invention, and this example prevents that aquaporin 29 inlet portion being provided with foreign matter from flowing into the little protuberance 42 of usefulness, and 43 is the suction inlets that formed by little protuberance 42 among the figure.
Figure 15 conduct shows the section shape that is provided with little protuberance 42 positions along the cutaway view of arrow E-E of Figure 14.
Also have, the 6th embodiment is provided with that have also can be from capturing near the aquaporin of the peristome of sprinkling water the upper flow gimbal 6 of outlet 51 roughly the same height of aquaporin 25a of usefulness with yarn, when below common water level, washing, cleaning solution is spilt to washings.
