Description
Technical field
The present invention relates to a kind of sealing device of washing machine, especially relate to a kind of float type sealing device for water saving type full automatic washing machine.
Background technology
In the prior art, water saving type full automatic washing machine, the not water storage of outer bucket of washing machine when mainly being meant laundry, the washing machine that only interior barrel water storage is washed, such washing machine ratio water-filled automatic washing machine of inside and outside bucket while when laundry can be saved 20%～30% slurry.This water saving type full automatic washing machine is referring to Chinese invention patent 95117171.2 " automatic washing machine " and the disclosed content of utility model patent 97231435.0 " water saving type full automatic washing machine ", its design feature is, the inner interior bucket that is provided with of bucket (claims rotary barrel again outside, dehydration barrel), have only top for middle and lower part sidewall atresia and have a line is had the osculum of ring-type setting with delivery port and bottom center by the number dehydration that forms of holes staving, for realizing the not water storage of outer bucket, interior barrel drainage channel must be isolated with outer bucket, also is provided with sealing device between promptly outer barrel and interior barrel.
For above-mentioned sealing device, Chinese utility model patent 96228625.7 " sealing device between the inside and outside bucket of washing machine " and 01218004.1 " steel ladle of water saving automatic washing machine " have more detailed disclosure.As shown in Figure 1, be arranged on interior bucket 2 (being rotary barrel mentioned above) in the outer bucket 1 by pallet 5 (claim not only ring flange) with rotate back-up ring 6 (but also claiming obturating cup) and be fixed on together on the dehydrating shaft 18a, interior barrel 2 drainage channel comprises that the osculum 7 that penetrates pallet 5 and rotation back-up ring 6 of its bottom center ring-type setting reaches the seal closure 11 (claiming seal box, lid again) of the platform taper of barrel 1 bottom inside setting outside and the drain chamber 16 of outer barrel of 1 bottom surface formation, and this drain chamber 16 is through main water discharge outlet 15 connection main drainpipe 13, draining valve 14 and drainpipes 21.The sealing device that relates to for described drainage channel includes between internal 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 the sealing of holding the gap between the upper port of rotating back-up ring 6 that had of rotation back-up ring 6 and seal closure upper end central authorities, but in fact, the part connection that is two no relative motions owing to other gaps except the latter forms, adopt static sealing just can easily satisfy seal request, therefore, the real key of sealing device is for the above-mentioned listed latter---the sealing in the gap between rotation back-up ring 6 and the seal closure circle suitable for reading 11b.Because interior bucket 2 can be driven by dehydrating shaft 18a with respect to outer bucket 1 and rotate, realize the dehydration action, 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, i.e. sealing between them is an a kind of class rotary seal structure.As shown in Figure 1, 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, the above-mentioned sealing device of interior bucket dependence makes water can not flow to outer bucket 1, and simultaneously, because draining valve 14 cuts out, water can only be stored in interior bucket 2 and the drain chamber 16 when laundry.When dehydration, draining valve 14 is opened, the water that interior bucket is 2 li is discharged by described drainage channel, then, the rotation at a high speed of interior bucket, the water that is contained in the clothing rises along inner barrel wall under action of centrifugal force, and dewatering from top throws away with the delivery port (not shown), collect by outer bucket 1, receive drainpipe 21 through secondary water discharge outlet 4, secondary drainpipe 19 then and discharge.
Above-mentioned the deficiencies in the prior art part is: (1) is according to the hermetically-sealed construction of this routine of prior art, the lips and teeth that are sealing ring 10 are held the rotation back-up ring outer cylinder 6a of meeting high speed rotating all the time tightly, when rotating at a high speed, interior bucket can produce wearing and tearing, cause 10 life-spans of sealing ring short, make seal failure, because in the process of washing machine work, sealing is paid in two programs and is in the dynamic seal (packing) state, i.e. washing and dehydration procedure.Washing procedure: the angle that interior bucket 2 rotates is very little, and the relative motion of the lips and teeth of sealing ring 10 and rotation back-up ring outer cylinder 6a is very little, and sealing is paid can be considered and is in the static sealing that medium is arranged; But in dehydration procedure, rotation back-up ring outer cylinder 6a can be with the rotation at a high speed of interior bucket 2, rotating speed can be up to more than 800 rev/mins, the linear velocity of the lips and teeth of sealing ring 10 can reach more than the 4m/s relatively, and drained owing to the water in the drain chamber 16 this moment, the dry condition that is in no medium is paid in sealing, and it is again interference fit that sealing is paid, therefore the frictional force that is produced therebetween is very big, be easy to cause the wearing and tearing of the lips and teeth contact position that rotates back-up ring outer cylinder 6a and sealing ring 10, cause seal failure, the life-span that sealing is paid reduces.(2) as easy as rolling off a log generation noise in high-speed dry friction is paid in sealing.(3) frictional force is big, will consume the power of motor in a large number, causes when serious that motor will start difficult in the dehydration.(4) be difficult to guarantee sealing property on technology: concentricity just can have excellent sealing performance because the lips and teeth of sealing ring 10 and rotation back-up ring outer cylinder 6a should have preferably, but because its fixing link is too much and complicated, correlated parts has foozle unavoidably, particularly outer bucket 1 and seal closure 11 are large-scale plastics article, as easy as rolling off a log generation distortion is difficult to guarantee that they have good concentricity; Sometimes in order to remedy alignment error, can strengthen the assembling magnitude of interference of sealing lips and teeth, but so, can cause sealing the frictional force of paying and strengthen, more can aggravate the variety of problems of aforementioned (1)～(3) thereupon rotation back-up ring outer cylinder 6a.(5) in order to solve the problem of dynamic seal (packing), need to adopt wear-resisting, resistant material manufacturing rotation back-up ring 6, and in order to reduce the wearing and tearing that sealing is paid, rotation back-up ring outer cylinder 6a also should have higher precision and fineness, this all can cause the increase of cost, and, also must improve the composition of sealing ring 10 materials in order to solve noise and the raising life-span that dry friction produces, this also will cause the increase of cost.Follow this technical scheme and develop down, not only cost increases greatly, but also is difficult to obtain desirable technique effect, all thus development that limits this kind water saving type full automatic washing machine.
