Abstract

The utility model relates to a tumbling cylinder of a washing machine with clothing scrubbing strips on bulges, which comprises an outer cylinder and an inner cylinder, wherein a plurality of holes are arranged in the wall of the inner cylinder so that the inner part and the outer part of the inner cylinder are communicated, and a plurality of clothing scrubbing strips are distributed on bulges which are uniformly arranged on the circular ring-shaped inner wall of the inner cylinder. The tumbling cylinder of a washing machine with clothing scrubbing strips on bulges has the advantages that an original tumbling cylinder can be reformed, but the integral structure of the washing machine is unchanged and the detergency degree of clothing can be increased.

Description

The washing machine drum that has clothing-rubbing strip on the protuberance

The roller frame that the utility model relates to a kind of roller washing machine improves, and is the washing machine drum that has clothing-rubbing strip on a kind of protuberance specifically.

The cylinder of tumbling-box washing machine includes urceolus and inner core, and dividing on the annular barrel of inner core all has a lot of holes, and inner core inside is connected with the inner core outside.Even three protuberances that distribute promptly stretch to another side from a side of inner core on the inner core annular inner tube wall.When inner core rotated, protuberance tangled superjacent clothes and rotates with inner core, and when forwarding tip position to, because the gravity effect, the clothing that is suspended falls, and some drops on the protuberance of bottom, because current and effect of inertia, dirt can be washed off on the clothing.Its shortcoming is that bump surface is smooth, upwards hangs the strength of clothing and clothing and drops on the effect of beating on the protuberance, and is not very good, removes the dirt ability.

The utility model purpose is to overcome the shortcoming in the above-mentioned technology, proposes to have on a kind of protuberance the washing machine drum of clothing-rubbing strip, makes when inner core rotates, clothing can be hung up better, when clothing falls, when beating clothing, increase frictional force, improve the wash degree of clothing.

The utility model purpose is realized by following technical scheme: the washing machine drum that has clothing-rubbing strip on this protuberance, comprise urceolus and inner core, on the inner core annular wall many holes are arranged, make inner core inside and external communications, it is characterized in that on the ring-shaped inner wall of inner core, equally distributed and be fixedly connected at protuberance on the inwall, its external surface shape is many clothing-rubbing strips that have that resemble the wash-board surface.

The shape approximation triangular prism shape of protuberance, three drift angle places are rounding off.

Protuberance is three, 120 degree of being separated by evenly distribute, the length of protuberance is identical with the inner core degree of depth, perhaps protuberance is 6,60 degree of being separated by evenly distribute, and the length of protuberance is half of the inner core degree of depth, wherein 3,120 degree of being separated by are evenly distributed on an end of inner core, and other 3 also is that 120 degree of being separated by are evenly distributed on the other end of inner core.

The approximate triangular prism shape of protuberance, three drift angle places are not sharp sharp drift angles, washing process can not hung bad clothing.When inner core rotates, the protuberance that has rubbing, be easier to the clothing in the inner core is hung up, when turning to the top, clothing is because gravity when falling, fall on the protuberance that has rubbing, except because inertia and the water impact effect, clothing is beaten to be had on the protuberance of many rubbings, can increase between the clothing and rub, more flush away dirts, the wash degree of increase clothing.

The utility model advantage is that structural change is little, and is easily manufactured, owing to set up clothing-rubbing strip on protuberance, the tumbling-box washing machine overall structure is constant, just can improve the wash degree of clothing.

Embodiment of accompanying drawings:

Fig. 1 is the washing machine drum structural perspective that has clothing-rubbing strip on a kind of protuberance,

The washing machine drum that has clothing-rubbing strip on this protuberance comprises urceolus (1) and inner core (2), and a plurality of apertures (5) are arranged on the annular barrel in inner core (2), and tube inner chamber communicates with inner core exocoel, outer tube inner chamber in making.On the inner core ring-shaped inner wall, have the approximate triangular prism shape of 6 protuberances (3), the drift angle rounding off, three protuberances (3) are near inner core the inner, 120 degree of being separated by, other three protuberances (3) are near the inner core outer end, be separated by 120 the degree, protuberance (3) is gone up and is rough shape, and the clothing-rubbing strip (4) of many raised items on wash-board is arranged.Be separated by between 6 protuberances 60 the degree.

Claims

1, the washing machine drum that has clothing-rubbing strip on a kind of protuberance, comprise urceolus and inner core, on the inner core annular wall many holes are arranged, make inner core inside and external communications, it is characterized in that on the ring-shaped inner wall of inner core, equally distributed and be fixedly connected at protuberance on the inwall, its external surface shape is many clothing-rubbing strips that have that resemble the wash-board surface.

2, according to the washing machine drum that has clothing-rubbing strip on the described protuberance of claim 1, it is characterized in that the shape approximation triangular prism shape of swelling, three drift angle places are rounding off.

3, according to the washing machine drum that has clothing-rubbing strip on the described protuberance of claim 1, it is characterized in that protuberance is three, 120 degree of being separated by evenly distribute, and the length of protuberance is identical with the inner core degree of depth.

4, according to the washing machine drum that has clothing-rubbing strip on the described protuberance of claim 1, it is characterized in that: protuberance is 6,60 degree of being separated by evenly distribute, the length of protuberance is half of the inner core degree of depth, wherein 3,120 degree of being separated by are evenly distributed on an end of inner core, and other 3 also is that 120 degree of being separated by are evenly distributed on the other end of inner core.
