Embodiment 1
The present embodiment provides barrel washing machine in a kind of atresia, as it is shown in figure 1, include interior bucket 1, outer barrel 2 and black box 3, the drum head 11 of interior bucket 1 is provided with interior bucket outlet 12, and the drum head 21 of outer barrel 2 is provided with outer barrel outlet 22；Black box 3 includes upper water-out pipe 31, sealing ring 32 and lower discharging tube 33, upper water-out pipe 31 is fixedly connected on the drum head 11 of interior bucket 1 and is coaxially disposed with interior bucket 1, interior bucket outlet 12 is positioned at inside upper water-out pipe 31, lower discharging tube 33 is fixedly connected on the inner surface of drum head 21 of outer barrel 2, outer barrel outlet 22 is positioned at the inner side of lower discharging tube 33, between upper water-out pipe 31 and lower discharging tube 33, there is annular gap, sealing ring 32 seals and is arranged in annular gap, sealing ring 32 includes coaxial and radially spaced inner ring 321 and outer ring 322, and the elastic joint part 323 between inner ring 321 and outer ring 322。
Barrel washing machine in the atresia that embodiments of the invention provide, sealing ring 32 is sealingly disposed in annular gap so that the water in interior bucket 1 cannot flow between interior bucket 1 and outer barrel 2。When there is eccentric rotary in interior bucket 1, the upper water-out pipe 31 being connected on the drum head 11 of interior bucket 1 there will be radial deflection, sealing ring 32 can be produced extruding by upper water-out pipe 31, owing to sealing ring 32 includes inner ring 321 and the outer ring 322 that coaxial and spaced radial is arranged, connected by elastic joint part 323 between inner ring 321 and outer ring 322, therefore extruding force can act on elastic joint part 323 in transmittance process, major part extruding force is made to be absorbed by elastic joint part 323, thus reducing the extruding force of the upper water-out pipe 31 that radial deflection the occurs inner ring 321 to sealing ring 32 or outer ring 322, frictional force between inner ring 321 or the outer ring 322 of upper water-out pipe 31 and sealing ring 32 will not be increased considerably, thus aggravating the situation of sealing ring 32 abrasion when avoiding interior bucket 1 eccentric rotary, extend the service life of sealing ring 32。
Upper water-out pipe 31 can be made during interior bucket 1 eccentric rotary to produce radial deflection, so that the side of sealing ring 32 is squeezed, make this be extruded the annular gap of side to reduce, causing that this is extruded the elastic joint part of side 323 and produces certain compression, this just requires that elastic joint part 323 has good compressibility。As it is shown on figure 3, when elastic joint part 323 is set to the spring that two ends are respectively fixedly connected with on inner ring 321 and outer ring 322, elastic joint part 323 has not only possessed good compressibility and restorative and durable, extends the service life of sealing ring 32。Simultaneously as linked together by the inside and outside circle of sealing ring 32 by spring, this makes there is radial clearance between the inside and outside circle of sealing ring 32, thus sealing ring 32 also includes a seal stopper ring 34 in use, so that this radial clearance is blocked sealing。Simultaneously, for guaranteeing the sealing of sealing ring 32, the upper surface of the inner ring 321 of sealing ring 32 and the upper surface of outer ring 322 are resisted against on seal stopper ring 34, or the lower surface of the lower surface of inner ring 321 and outer ring 322 is resisted against on seal stopper ring 34, thus avoiding the water in interior bucket 1 to flow between inside and outside bucket by this radial clearance, wherein, the upper surface of inner ring 321 refers to the inner ring 321 end face near interior bucket 1, and its lower surface refers to the inner ring 321 end face away from interior bucket 1 one end relative with upper surface；The upper surface of outer ring 322 refers to the outer ring 322 end face near interior bucket 1, and its lower surface refers to the outer ring 322 end face away from interior bucket 1 one end relative with upper surface。
Specifically, the structure of sealing ring 32 includes a vertical ring respectively as it is shown on figure 3, the inner ring 321 of sealing ring 32 and the cross section of outer ring 322 are L-shaped, inner ring 321 and outer ring 322, and is sealedly attached to a horizontal loops of one end of vertical ring；Seal stopper ring 34 leans with the horizontal loops 3211 of inner ring 321 and the horizontal loops 3221 of outer ring 322 respectively, in order to be connected to as the two ends of the spring of elastic joint part 323 on the vertical ring 3212 of inner ring and the vertical ring 3222 of outer ring。When the cross section of inner ring 321 and outer ring 322 is L-shaped, contact area between seal stopper ring 34 and inner ring 321 and outer ring 322 is bigger, this makes when interior bucket 1 eccentric rotary causes that upper water-out pipe 31 produces radial deflection, seal stopper ring 34 all the time by the radial clearance seals between inner ring 321 and outer ring 322, can ensure that stability when this black box 3 works。
Alternatively, sealing ring 32 is it can also be provided that structure as shown in Figure 4, the cross section of inner ring 321 and outer ring 322 is rectangle, seal stopper ring 34 leans with the upper surface of the upper surface of inner ring 321 and outer ring 322 respectively, in order to be connected on inner ring 321 and outer ring 322 as the two ends of the spring of elastic joint part 323。Alternatively, seal stopper ring 34 can also lean with the lower surface of the lower surface of inner ring 321 and outer ring 322 respectively。
If seal stopper ring 34 is not fixed when mounted, the vibrations that washing machine produces in rotation process likely can cause that skew occurs in the position of seal stopper ring 34, if the skew of seal stopper ring 34 is excessive, arise that seal stopper ring 34 cannot fully seal the radial clearance between inner ring 321 and outer ring 322, cause seal failure。Therefore, for ensureing stability when seal stopper ring 34 works, as depicted in figs. 1 and 2, seal stopper ring 34 is fixed be connected with upper water-out pipe 31 or lower discharging tube 33, now, no matter it is that washing machine produces vibrations in operation process, or during interior bucket 1 eccentric rotary, upper water-out pipe 31 produces radial deflection, seal stopper ring 34 all the time by the radial clearance seals between inner ring 321 and outer ring 322, can ensure that stability when this black box 3 works。
For making the simple in construction of sealing ring 32, production cost reduces, rubber can be adopted to make sealing ring 32, the elastic joint part 323 of this sealing ring 32 is ring-shaped rubber part simultaneously, elastic joint part 323 and inner ring 321 and outer ring 322 integrated injection molding, now the radial clearance between the inside and outside circle of sealing ring 32 is fully sealed by this ring-shaped rubber part, seal that structure is come internally, radial clearance between outer ring blocks sealing without additionally arranging, simplify the structure of sealing ring 32, and owing to elastic joint part 323 and inside and outside circle are one-body molded, production difficulty is substantially reduced。Simultaneously; for guaranteeing that the extruding force major part that interior bucket 1 produces when eccentric rotary acts on elastic joint part 323; the coefficient of elasticity of this ring-shaped rubber part is less than the coefficient of elasticity of inner ring 321 with outer ring 322; this makes to be more prone to deformation as the ring-shaped rubber part of elastic joint part 323; thus protecting inner ring 321 and the outer ring 322 of sealing ring 32, it is to avoid the abrasion aggravation that the extruding force produced when the inside and outside circle of sealing ring 32 is due to interior bucket 1 eccentric rotary causes。
Alternatively, elastic joint part 323 is it can also be provided that the form of ring bellows, and when interior bucket 1 eccentric rotary, the extruding force of generation makes the elastic joint part 323 of corrugated tube shape produce deformation, thus protecting inner ring 321 and the outer ring 322 of sealing ring 32。
Black box 3 may be configured as that upper water-out pipe 31 is little and form that lower discharging tube 33 is big, specifically, as shown in Figure 2, when the external diameter of upper water-out pipe 31 is less than the internal diameter of lower discharging tube 33, upper water-out pipe 31 is positioned at lower discharging tube 33 away from one end of the drum head 11 of interior bucket 1, on, annular gap between lower discharging tube is surrounded by the inwall of lower discharging tube 33 and the outer wall of upper water-out pipe 31, now will be located in that the inwall of the outer ring 322 of the sealing ring 32 in annular gap and lower discharging tube 33 is fixing to be connected, the inner ring 321 of sealing ring 32 seals laminating with the outer wall of upper water-out pipe 31 and can relatively rotate, when interior bucket 1 drives upper water-out pipe 31 to rotate, remain sealing laminating between outer wall and the inner ring 321 of sealing ring 32 of upper water-out pipe 31 and produce relative rotation, under ensureing the premise of sealing of black box 3, ensure that the normal operation of barrel washing machine in this atresia。
Be fixedly connected on the inwall of lower discharging tube 33 by the outer ring 322 of sealing ring 32 can to adopt securing member connect, the mode such as bonding or interference fit。Adopting securing member connected mode to need in perforate to hold securing member, this connected mode consuming operation is more and installs inconvenience, and even when sealing ring 32 bears bigger load, tapping easily occurs that breach even ruptures。Employing bonding way is fixedly connected, and its cost easy and simple to handle is not high, but the bond medium for bonding outer ring 322 and lower discharging tube 33 easily lost efficacy in use for some time, thus causing that outer ring 322 and lower discharging tube 33 disengage。And adopt the mode of interference fit to be fixedly connected, and only need to the outer ring 322 of sealing ring 32 be loaded in lower discharging tube 33, intensity easy and simple to handle and connecting portion is higher, it is not easy to the situation of Joint failure occur。
Interior bucket 1 is in the process of eccentric rotary, can cause that the skew on radially direction occurs in the upper water-out pipe 31 being fixedly connected on interior bucket 1, now offset away from upper water-out pipe 31 and there will be gap between the inner ring 321 of side and upper water-out pipe 31, as shown in Figure 2, black box 3 also includes fastening piece 35, adopt fastening piece 35 by inner ring 321 together with upper water-out pipe 31 lock ring after, upper water-out pipe 31 is when there is skew, inner ring 321 simultaneous bias can be driven, guarantee that the outer wall of upper water-out pipe 31 and the inner ring 321 of sealing ring 32 remain sealing laminating, avoid offseting away from upper water-out pipe 31, between the inner ring 321 of side and the outer wall of upper water-out pipe 31, gap occurs, thus ensure that the sealing of black box 3。
Specifically, as in figure 2 it is shown, can be larynx hoop or garter springs for the inner ring 321 of captive closure circle 32 and the fastening piece 35 of upper water-out pipe 31, larynx hoop or garter springs be circumferentially positioned on the inner ring 321 of sealing ring 32 side away from upper water-out pipe 31。When using larynx hoop as fastening piece, first the interior cranse of larynx hoop is set on the inner ring 321 of sealing ring 32 side away from upper water-out pipe 31, then screw the bolt on larynx hoop, make interior cranse tighten up, the inner ring 321 of sealing ring 32 and upper water-out pipe 31 are linked together。Larynx hoop self is inexpensive, simple to operate, but due to the existence of bolt so that larynx hoop own vol is relatively big, must leave enough installing spaces, be unfavorable for the installation in small space in use procedure。And when selecting garter springs to make fastening piece 35, can directly select the garter springs that internal diameter is slightly less than inner ring 321 external diameter to be set on the inner ring 321 of sealing ring 32 side away from upper water-out pipe 31, utilize the restoring force of garter springs self inner ring 321 and the upper water-out pipe 31 of sealing ring 32 to be linked together。For reducing the difficulty being set on the inner ring 321 of sealing ring 32 by garter springs, the number of turns as the garter springs of fastening piece 35 can simply be a circle, recline owing to outer wall near the side of upper water-out pipe 31 Yu upper water-out pipe 31 of the inner ring 321 of sealing ring 32 is seamless, therefore restoring force produced by a circle garter springs is enough to ensure that when radial deflection occurs in upper water-out pipe 31, does not have gap between the outer wall of inner ring 321 and upper water-out pipe 31。
In washing complete and the process of dehydration, water in interior bucket 1 all needs the interior bucket outlet 12 on the drum head 11 through being arranged on interior bucket 1 to discharge, therefore, for improving the drainage efficiency of interior bucket 1, promoting Consumer's Experience, the drum head 11 of interior bucket 1 is provided with some interior bucket outlets 12, and in these, bucket outlet 12 is on the drum head 11 of interior bucket 1, the rounded uniform arrangement with the center of rotation of drum head 11 for the center of circle, thus the expulsion efficiency of the water that improve in interior bucket 1。
