    Description

    This invention relates to washing machines, and more particularly to Washing machines having rotatable tubs provided with improved centrifugally operated valve means <a href="http://www.sellercrusher.com/solutions/limestone-grinding-mill.html">limestone grinding mill</a>.Among the objects of the invention is to provide a washing machine with an improved rotatable tub construction which when rotated at a relatively high speed provides a means for removing heavy particles of dirt and foreign matter therefrom.


    In washing machines having rotatable tubs wherein a washing operation and a centrifugally drying operation takes place there are times, when washing some fabrics, that heavy particles of dirt, sand, etc. will settle out of the fabrics being washed. These particles tend to collect in the bottom of the tub during the washing operation and when the tub is rotated to extract the liquid a portion of the heavy dirt or foreign matter may be forced back into some of the fabrics which,<a href="http://www.sellercrusher.com/solutions/gold-ball-mill.html">gold ball mill</a> of course, causes the same to be spotted or soiled. Even in installations wherein a space or sediment trap is provided for heavy dirt to settle out of contact of the fabrics being washed, the dirt is not always removed therefrom when the tub is rotated and it may accumulate therein until it eventually clogs the sediment trap. This is especially so in installations where the settling space is not readily accessible for manual cleanmg.


    Accordingly it is an object of the invention to provide a washing machine having a rotatable tub which is provided with a settling space at the lower portion thereof for heavy particles of dirt and to remove the same from the space centrifugally through a passage at the lower portion of the tub when the tub is rotated.It is another object of the invention to provide a washing machine having a rotatable tub which is provided with a space at the lower lportion thereof for the accumulation of heavy particles of dirt during the washing operation and centrifugally operated resilient valve means disposed about a circumferential passage in the periphery of the tub capable of preventing leakage when the tub is stationary and which is opened by centrifugal force when the tub is rotated at relatively high speed to permit a direct flushing action of water through the space to remove the particles of dirt therefrom.
