Describe in detail

With reference to the accompanying drawings, the exotic that prevents of describing a tumbling-box washing machine of the prior art now flows into structure.

Here, the basic structure of tumbling-box washing machine of the present invention is identical with the basic structure of prior art, has therefore omitted its general structure, and only illustrates that the exotic that prevents related to the present invention flows into structure.

Fig. 4 is that an of tumbling-box washing machine of the present invention prevents that exotic from flowing into the profile of structure.Fig. 5 is a profile along II-II ' intercepting among Fig. 4; And Fig. 6 is a profile along III-III ' intercepting among Fig. 4.

As shown in FIG., a sealing ring 100 comprises a folded part 110, this folded part 110 is used to absorb the vibrations of the outer bucket 300 that is produced by the rotation of interior bucket 200, with one prevent that exotic from flowing into wall 120, this prevent exotic flow into wall 120 be used for preventing article 400 for example a coin flow between bucket and the outer bucket 200,300.

Prevent that exotic from flowing into wall 120 and comprising a projection 130, this projection 130 stretches to folded part 110 from the center.Projection 130 prevents exotic 400 outflows of folded part 110 inboards and imports interior bucket with outward between the bucket 200,300., the rotation of interior bucket 200 flows out because thereby causing outer bucket 300 vibrations to produce exotic 400.

At this moment, the current in folded part 110 form a kind of curved path, and therefore the exotic 400 that flows into is hooked by projection 130, thereby prevents its outflow.

And, a upper angled of projection 130, exotic 400 is easy to flow into but is difficult to and flows out like this.

Simultaneously, sealing ring 100 is also additional to comprise that one first prevents that exotic from flowing into projection 140 and one second and preventing that exotic from flowing into projection 150, this first prevent exotic flow into projection 140 and second prevent exotic flow into projection 150 respectively from prevent a bottom that exotic flows into wall 120 inwardly bucket 200 stretch.

First prevent exotic flow into projection 140 be formed on the part of sealing ring 100 of inlet 210 belows of bucket 200, and barrels 200 a top in pointing to with being inclined upwardly.

Second prevent exotic flow into projection 150 be formed between the sweep of bucket 200 and outer bucket 300, wherein second prevent that top that exotic flows into projection 150 from becoming curved and towards preventing that exotic from flowing into wall 120.

At this moment, it is both thin and have flexiblely that second of formation prevents that exotic from flowing into the bend of projection 150, is worn when during turning contacting with interior bucket 200 preventing.

Simultaneously, the distance D from interior bucket inlet 210 to the groove 160 that prevents exotic inflow wall 120 bottoms is less than the diameter of the minimum coin that uses at present.

Prevent to flow between the inlet 210 of wall 120 and interior bucket 200 although exotic 400 flows into, as shown in Figure 4, because second prevents that exotic from flowing into stopping of projection 150, exotic is erectly stayed in the gap between the inlet 210 that prevents to flow into wall 120 and interior bucket 200, thereby prevents that coin from flowing into.And because the part of coin is exposed to the outside, the user can remove coin easily.

As illustrated in Figures 5 and 6, in order to prevent since swing that the rotation of interior bucket 200 produces or vibrations sealing ring 100 is tilted and causes preventing that exotic from flowing into wall 120 distortion, on the periphery of sealing ring 100, form anti-inclined ribs 170, and preventing that exotic from flowing into the lower inside layout anti-deformation rib 180 of wall 120.

At this moment, anti-inclined ribs 170 is arranged on the outside of sealing ring 100, and corresponding with the part that anti-deformation rib 180 is installed on installation interval.

Figure notation 500 is an interlock clip being connected with enhanced leaktightness circle 100 and outer bucket 300.

Flow in the tumbling-box washing machine of structure having the exotic that prevents of the present invention, will explain an example, wherein in laundry run duration exotic 400 is stayed in barrels 200.

At first, when the inlet 210 of the exotic 400 inside buckets 200 in the interior bucket 200 moves and flows between the folded part 110 that prevents exotic inflow wall 120 and sealing ring 100, exotic 400 is along the level and smooth inflow of the inclined upper surface of projection 130, and this projection 130 is from preventing that exotic from flowing into wall 120 and stretching to the folded part 110 of sealing ring 100.Because the current in folded part 110 turn under projection 130 effects, the exotic 400 of inflow can't flow out.

Here, if the exotic 400 inwardly inlet 210 of bucket 200 moves and flows into the inlet 210 of interior bucket 200 and prevents that exotic from flowing between the wall 120, because first prevents that exotic from flowing into projection 140 and second and preventing that exotic from flowing into the effect of projection 150, exotic 400 is obstructed and can't enters, thereby bucket and outer bucket 200,300 and heating element (not shown) are impaired in preventing.

As mentioned above, the exotic inflow structure that prevents of a tumbling-box washing machine is convenient in the folded part of exotic inflow sealing ring, and prevent that exotic from flowing between the interior bucket and outer bucket of washing machine, can also prevent ring wear, thus this wearing and tearing be since rotate make in the bucket swing or tilt to cause exotic contact with sealing ring produce.

Because do not exceeding under the essence prerequisite of essential characteristic of the present invention, the present invention can adopt various ways to embody, should understand the foregoing description not limited by above-mentioned any details, unless otherwise mentioned, extensively comprise in essence that Ying Zaiben claims limit and the scope, therefore, the institute that meets these claims changes and modification and equivalents thereof all are included in these claims.
