By adopting above-mentioned technical scheme, the utility model improves the interior barrel structure of washing machine, outside on the annular protrusion of inner drum, being provided with little in big perforate, cancellation line bits filter, reduced cost, improved product competitiveness, simultaneously, the user is without manual cleanup line bits filter, and product is hommization more.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Fig. 1 is the complete machine schematic diagram of the utility model washing machine;

Fig. 2 is the inner drum schematic diagram of the utility model washing machine inner tub;

Fig. 3 is the partial enlarged drawing of Fig. 2;

Fig. 4 is the enlarged drawing at A place among Fig. 3;

Fig. 5 is the perforate most preferred embodiment, and direction of observation is a mind-set bucket wall from interior bucket.

The specific embodiment

The part of number in the figure representative is:

1 washing machine, 2 outer buckets, bucket in 3,4 gimbals, 5 inner drums, 51 perforates, 511 perforate outer faces, 512 perforate inner faces, 52 annular protrusion bands, wear 53 inner drum Yuanping City, in 6 barrel at the bottom of, 7 impellers

Referring to Fig. 1, the described washing machine of the utility model technology is shown.Washing machine 1 comprises casing, outer bucket 2, interior bucket 3, impeller 7, transmission system, control system etc., bucket 3 was made up of gimbal 4, metal inner drum 5, the interior bucket end 6 wherein, perforate 51 on the inner drum flange that tilts from inside to outside forms, and is the big shape in little the inner, outer end.Hole on this inner barrel wall is interior big outer little trumpet-shaped flange hole.

By adjusting the washing current, allow the washing current form and be passed down through the impeller and the interior bucket end, from up between the inside and outside bucket, pass inner barrel wall cardiocirculatory state in bucket then from interior bucket center, thereby the bits of the line in the current are filled into interior bucket outer wall, when draining, the line bits are discharged outside the bucket.

Particularly, referring to Fig. 2 to Fig. 4, the inner drum structure of washing machine inner tub described in the utility model is shown.The bucket of washing machine inner tub body has a plurality of perforates on the wall, and the perforate flange that tilts from inside to outside forms, and is the big shape in little the inner, outer end.

Referring to Fig. 4, Fig. 5, be the most preferred embodiment of perforate described in the utility model.Perforate is a bar hole, and bar shaped perforate outer face 511 is of a size of 1mm * 3mm, and the perforate outer face is 25 °-35 ° to the flange angle of inclination between the inner face, and the best is 30 °.The spacing range of horizontal adjacent two perforates of inner drum is 10-20mm, and vertically the spacing range of adjacent two perforates is 20-30mm.That is to say, in the time of in washings are flowed through by in entering once more to inside and outside bucket at the bottom of the impeller in the interior bucket barrel, 1mm * 3mm perforate had both guaranteed that water can enter in the interior bucket smoothly, the line bits can be filtered between inside and outside bucket again, bucket in the passing siding bits do not enter into once more avoids the line bits to be stained with on the clothing.

The bucket wall of washing machine inner tub body is circumferentially having many annular protrusion bands 52 to External Pressure Type, perforate 51 is evenly distributed on the position, plane in the middle of the annular protrusion band, there is inner drum Yuanping City to wear 53 between the annular protrusion band 52, the annular protrusion band 52 of staving is arranged with the primary plane tape alternation, the size range that the annular protrusion face of washing machine inner tub body exceeds the inner drum primary plane is 3mm-6mm, and the vertical section of staving bucket wall is wavy.This bucket wall is wavy structure, on the one hand, the inner surface injustice of interior bucket is similar to washboard, be beneficial to the wash degree that improves clothing, on the other hand, in the bucket time, line is considered to be worth doing and is blocked by the perforate flange easily in the washings that have line bits between the bucket are entering inside and outside the washing machine, be trapped in the groove of these wavy interior bucket outer walls, the line bits are discharged from when draining.。

Another embodiment of the staving perforate of washing machine inner tub described in the utility model (not having figure to illustrate).Perforate is a circular port, and Kongzui little internal diameter in outer end is 1-2mm, and perforate flange gradient is 25 °-35 °, and in this case, because the area of round hole is little with respect to bar hole, therefore, the density of perforate is wanted corresponding increasing.

In sum, by above-mentioned technical scheme, the washing machine inner tub that the utility model provides, improved the open-celled structure on the inner barrel wall, add adjustment, realize current center line bits being filtered, save line bits filter by inner drum to the washing current, and when draining, will filter out the line bits that exist between the inside and outside bucket and discharge, need not user's manual cleanup line bits.Not only reduce cost, simplified technology, and the user uses convenient.

Bucket open-celled structure in of the present utility model can be used on rotary drum washing machine, stirs on the products such as washing machine, two-power washing machine.

Certainly, the utility model is not limited to above-mentioned giving an example, the technical scheme that it will be apparent to those skilled in the art that, under the situation that does not break away from spirit or scope of the present utility model, the utility model is made various modifications and changed in the utility model claim and be equal in the scope of replacement, and the utility model is contained such modification and change.
