Technical field
The present invention relates to a kind of water-saving type laundry machine, the water discharge method of water-saving type laundry machine and use the water saving type full automatic washing machine of this method especially, classification belongs to D06F39/08 in the International Patent Classification (IPC).
Background technology
For prior art impeller-type or stirring type fully-automatic washing machine, outer bucket (claiming steel ladle again) not water storage when water-saving type laundry machine is meant laundry, the washing machine that only interior barrel (claiming rotary barrel, dehydration barrel again) water storage is washed; It is than conventional washer water saving (20～30) %.
The Chinese invention patent 95117171.2 " automatic washing machine " of this washing machine visible Toshiba Corp of technical scheme early and the applicant's Chinese utility model patent ZL97231435.0 " water saving type full automatic washing machine ".Its design feature is seen Fig. 1, similar with conventional washer, centre bore 1a by motor bucket 1 outside the last columella fixed part cover sealing ring 17 of the speed-reducing clutch 18 of belt pulley transmission is fixed in, interior bucket 2 in the outer bucket 1 is fixed on dehydrating shaft (the claiming outer shaft again) 18a together by pallet 5 and rotation back-up ring 6, be the wash shaft that connects impeller (claim not only stirring wheel) 3 coaxial rotations (but also in claiming axle) 18b in the 18a, interior bucket 2 has downward drainage channel.Its change with respect to conventional washer is: an interior bucket middle and lower part sidewall atresia and circle dehydration apopore is arranged at top; Interior bucket 2 downward drainage channels are provided with the hermetically-sealed construction with outer bucket 1 isolation, make the not water storage of outer bucket.The sealing structure mainly is that the osculum 7 that penetrates pallet 5 and rotation back-up ring 6 of interior barrel of bottom center ring-type setting reaches the seal closure 11 of the platform taper of barrel 1 bottom inside setting outside and the drain chamber 16 of outer barrel of 1 bottom surface formation.This drain chamber is communicated with main drainpipe 13, draining valve 14 and drainpipe 47 through main water discharge outlet 15, and has connecting hole 92, is used to connect the pressure sensor of sensed water level.In seal clearance is distributed between bucket 2 and the pallet 5, between rotation back-up ring 6 and the pallet 5, between seal closure 11 and the outer bucket 1 and rotation back-up ring 6 and seal closure upper end central authorities holding between the upper port of rotating back-up ring 6 of being had.Wherein, interior bucket 2 can be driven by dehydrating shaft 18a with respect to outer bucket 1 and rotate, and realizes the dehydration action, and rotation back-up ring 6 also can rotate with interior bucket 2.Therefore, there is relative motion in rotation back-up ring 6 with respect to seal closure 11, and sealing therebetween belongs to a class rotary seal structure.Gap between rotation back-up ring outer cylinder 6a and the seal closure circle suitable for reading 11b 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 6a interference fit on lips and teeth and following lips and teeth.During laundry, inwardly bucket 2 water fillings, interior bucket relies on described sealing to make water not flow to outer bucket 1; Because draining valve 14 cuts out, water can only be stored in interior bucket 2 and the drain chamber 16 simultaneously.Before the dehydration, draining valve 14 is at first opened, and the water that interior bucket is 2 li 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 1, receives drainpipe 47 through secondary water discharge outlet 4, secondary drainpipe 19 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 6a all the time tightly, friction when interior bucket rotates at a high speed, there is tangible life-span, noise and excessive power drain (even influence starts) problem, need suitable structural design, technology and material to improve, thereby cause the increase of cost.In addition, the hermetically-sealed construction in being present between bucket outer bottom and the outer bucket inner bottom part has increased volume (highly) with respect to conventional washer, and Change In Design is bigger; The chance that the water in formed water chamber is obviously wasted and increase is leaked.Owing to above reason, though this kind water saving type full automatic washing machine has been seen listing, slower development.
