The washing machine technical scheme that addresses this problem early can be referring to the Chinese invention patent 95117171.2 " automatic washing machine " of Toshiba Corp and the applicant's Chinese utility model patent ZL97231435.0 " water saving type full automatic washing machine ".Its design feature is, the interior bucket middle and lower part sidewall atresia that is provided with in the bucket outside and osculum that top has a circle dehydration apopore and bottom center to have annular distribution.For making the not water storage of outer bucket, the drainage channel of interior bucket is provided with the hermetically-sealed construction of isolating with outer bucket.The sealing structure is referring to Fig. 2.Wheeled or stirring type fully-automatic washing machine is similar with conventional wave, be fixed in outer barrel 3 ' centre bore 3a by motor through the last columella fixed part cover sealing ring 11 of the speed-reducing clutch 10 of belt pulley transmission.Interior bucket 5 ' outside being arranged in the bucket 3 ' is fixed on dehydrating shaft 10a upward (the wash shaft 10b that is connected agitator 4 in the 10a in addition) together by pallet 9 and rotation back-up ring 32, interior barrel 5 ' drainage channel comprises that the osculum 21 that penetrates pallet 9 and rotation back-up ring 32 of its bottom center ring-type setting reaches the seal closure 31 of the platform taper of barrel 3 ' bottom inside setting outside and the drain chamber 16 of outer barrel of 3 ' bottom surface formation, this drain chamber 16 is communicated with main drainpipe 33, draining valve 13 and drainpipes 47 through main water discharge outlet 15, and offers the connecting hole of the level sensor that is used to connect washing machine.As seen, in the sealing structure comprises between bucket 5 ' and the pallet 9, between rotation back-up ring 32 and the pallet 9, between seal closure 31 and the outer bucket 3 ' and the sealing of holding the gap between the upper port of rotating back-up ring 32 that had of rotation back-up ring 32 and seal closure upper end central authorities.Wherein, the part that other gaps except that the latter are two no relative motions connects and forms, and adopts static sealing just can easily satisfy seal request.Therefore, the key of sealing is the sealing to this latter.Interior bucket 5 ' can be driven by dehydrating shaft 10a with respect to outer bucket 3 ' and rotate, realization dehydration action, and rotation back-up ring 32 also can rotate with interior bucket 5 '.Therefore, there is relative motion in rotation back-up ring 32 with respect to seal closure 31, i.e. sealing between them is an a kind of class rotary seal structure.Gap between rotation back-up ring outer cylinder 32a and the seal closure circle suitable for reading 31b is by sealing ring 10 sealings, sealing circle 10 constitutes by the tubular outer rim that is positioned at medial and lateral and with the annular upper limb that two outer rims join together, the upper/lower terminal of inner edge have respectively slope inwardly extend with rotation back-up ring outer cylinder 32a interference fit on lips and teeth and following lips and teeth.During laundry, inwardly bucket 5 ' water filling, interior bucket relies on described sealing to make water not flow to outer bucket 3 '; Because draining valve 13 cuts out, water can only be stored in interior bucket 5 ' and the drain chamber 16 simultaneously.When dehydration, draining valve 13 is at first opened, and the water in the interior bucket 5 ' is discharged through described drainage channel; Then, interior bucket is rotation at a high speed, and the water of clothing rises at centrifugal action lower edge inner barrel wall, throws away from the dehydration apopore on top, is collected by outer bucket 3 ', receives drainpipe 47 through secondary water discharge outlet 34, secondary drainpipe 35 then and discharges.The deficiency of the prior art is that the lips and teeth of sealing ring 10 hold rotation back-up ring outer cylinder 32a all the time tightly, has friction when interior bucket rotates at a high speed.The ill effect of this friction is: there is tangible life problems in (1) sealing pair; (2) produce friction noise; (3) additive decrementation power of motor can start difficulty when serious.In addition, the lips and teeth of sealing ring 10 and rotation back-up ring outer cylinder 32a should have preferably that concentricity just can have excellent sealing performance.Because fixing link is many and complicated, the unavoidable foozle of correlated parts, particularly outer bucket 3 ' and seal closure 31 are large-scale plastics article, are easy to generate distortion, very difficult assurance has good concentricity.Sometimes, for remedying alignment error, can strengthen the assembling magnitude of interference of sealing lips and teeth to rotation back-up ring outer cylinder 32a.But can cause the frictional force of sealing pair to strengthen like this, aggravate aforementioned (1)～(3) ill effect.For improving described friction problem, can adopt wear-resisting, resistant material manufacturing rotation back-up ring 32; Make rotation back-up ring outer cylinder 32a that higher precision and fineness be arranged; Improve the composition of sealing ring 10 materials.They all cause the increase of cost.Owing to above reason, though this kind water saving type full automatic washing machine has been seen listing, slower development.The deficiency of this water-conservation washing machine is: complex structure, and the technological requirement height is changed desired costing a lot of money, and is difficult to implement; And interior bucket outer bottom with outside a water chamber is all arranged between barrel inner bottom part, the water in the chamber is obviously wasted.
