Definitions
- the process of penetrating water into the fibers as well as the aid of mechanical movement to washing are obtained by means of rotating the drum both in clockwise and anti-clockwise directions with full rotations at a constant speed.
- the rotational speed of the said movement is generally around 50-55 rpm and this value is determined based on the diameter of the drum. So that the vertical component of the centrifugal force acting upon the clothes being washed is less than gravity before the top point of the drum, at which the clothes are dropped down to the bottom of the drum.
- One object of the present invention is to realize the rotational movements of any tub used in a washing machine as intermittent and with modulating oscillations, to increase or reduce the revolution cycle of the said tub with the desired acceleration that may be variable and to realize a method that provides an improvement in the washing performance by creating desired speed differences between water and clothes by means of stopping this movement at a desired angle and thus obtaining the intended falling angles and heights in desired cycles.
- Another object of the present invention is to realize a method to keep the wool clothes continuously in the water during washing cycle using less water, by applying to the drum the oscillating movements of variable amplitude and frequencies.
- FIG. 1 A general schematic drawing of an embodiment wherein the method realized to achieve the objects of the present invention is applied, is attached to this document.
- the tub is horizontally positioned and supported by the body (1) by using spring (3) and damper elements (2).
- the drum (5) is positioned in such a manner that it can perform rotational movements within the horizontal tub (4).
- Clothes (6) are loaded into the drum and washing is performed by means of rotation around the drum shaft axis (7).
- Drum movements are realized through the washing programmes selected according to the type of the fabric to washed.
- the drum rotates at approximately 3 rad/s 2 of angular acceleration and 20 rpm of rotational speed for 1.25 seconds clockwise and 1.25 seconds in counter-clockwise directions in order to meet the requirement of keeping the wool clothes to be washed continuously in water using less water and additionally in order to provide a better washing performance.
- the drum never makes a full (complete) revolution and performs an oscillating movement between the proper angle limit values towards both directions.
- better shrinkage performance values as compared to a standard wool programme, can be obtained although 40% less washing water is consumed for main wash.
- the above mentioned oscillating movement can also be applied in cotton washing programme.
- oscillation angles may reach to higher values compared to the wool programme during the washing cycle for cotton textiles.
- the fact that the acceleration acting upon the fabric during washing is variable improves the soil removal process off the clothes. By means of variable accelerations cleaning chemicals are carried into the pores of the fabric and soil removed off the fabric is carried away from the clothes more efficiently.
- oscillating movement is provided in progressive amplitudes thus obtaining the modulation of the acceleration acting upon the fabric in the course of time, for cotton washing cases where washing performance is more important.
- This movement which starts as small oscillations and progressively increases its amplitude until it reaches full-cycle levels, is repeated periodically all through the washing programme.
- Another factor increasing the washing performance is simulating the rubbing action used while hand washing by providing the friction of the fabrics being washed.
- the drum is rotated at such a speed that a centrifugal acceleration more than gravitational acceleration is obtained, thus the clothes in the tub are left immobile around the drum and the drum movement is suddenly stopped at 180° from the initial point, i.e. when the clothes are at the top point. As the result of this, the clothes within the drum fall off the peak point downwards and thus the washing performance is improved.
