(1) FIG. 1 illustrates an exemplary model of a balancing apparatus 100 that shows position of ball when the polarity of the poles of the half ring and the poles of the propellers facing each other are similar, according to the present invention.

DETAILED DESCRIPTION OF THE DRAWING

(2) FIG. 1 illustrates an exemplary model of a balancing apparatus 100 that shows position of ball when the polarity of the poles of the half ring 2 and the poles of the propellers 3 facing each other are similar, according to the present invention. The drum 1 is balanced using magnetic properties of the propellers 3 and the half rings 2. In order to achieve this, the present invention preferably comprises of a plurality of propellers 3 and at least two half rings 2.

(3) According to an embodiment of the invention, the propellers 3 and the half rings 2 are made up of magnetically polarizable materials. The plurality of propellers 3 is attached to the drum 1. The two half rings 2 are configured to cover the drum 1. The propellers 3 and the half rings 2 are magnetically polarized while electric current is passing through the propellers 3 and half rings 2. The drum 1 is balanced by forming similar polarity in poles of the half rings 2 and the poles of the propellers 3 facing each other. Thus, the propellers 3 inside the drum 1 are pushed by the external magnetic force applied by the half rings 2 outside the drum 1 and thus the drum 1 is balanced.

(4) This solution is beneficial since such a balancing apparatus 100 enables prevention of vibrations and loud running in a drum 1 of a washing machine while operating. While the washing machine is operating, the propellers 3 and the half rings 2 are magnetically polarized by passing electric current through the propellers 3 and the half rings 2. The drum 1 is balanced by forming similar polarity in the poles of the propellers 3 and the poles of the half rings 2 facing each other. Hence, the vibrations and loud running is prevented and the balancing of the drum 1 is achieved using magnetic property of the propellers 3 and the half rings 2. Additionally, implementation of such a balancing apparatus 100 is simple and effective.

(5) According to an embodiment of the invention, the balancing apparatus 100 further includes at least one ball 4 and a sensor 5. The ball 4 is placed between the half ring 2 and the drum 1. The ball 4 is magnetically polarized while the electric current is passing through the ball 4. The sensor 5 is configured for measuring the distance from the ball 4 to the drum 1 and the distance from the ball 4 to the half ring 2. The distance measured by the sensor 5 enables to determine whether the poles of the half rings 2 and the poles of the propellers 3 facing each other are similar or opposite.

(6) The poles of the half rings and the poles of the propellers facing each other are identified similar when the difference between the distance from the ball 4 to the drum 1 and distance from the ball 4 to the half ring 2 is zero. The poles of the half rings 2 and the poles of the propellers 3 facing each other are identified opposite when the difference between the distance from the ball 4 to the drum 1 and distance from the ball 4 to the half ring 2 is non-zero. The opposite polarity in the poles of the half rings 2 and the poles of the propellers 3 facing each other are changed to similar polarity by reversing the current flow through the half ring 2 and/or the propellers 3.

(7) Thus, the present invention provides a balancing apparatus 100 that prevents vibrations and loud running in a drum 1 of a washing machine while operating by using magnetic property and simple configuration. The balancing apparatus 100 according to the present invention preferably comprises of at least two half rings 2 and a plurality of propellers 3. The plurality of propellers is attached to the drum 1. The two half rings 2 are configured to cover the drum 1. The propellers 3 and the half rings 2 are magnetically polarized while electric current is passing through the propellers 3 and half rings 2. The drum 1 is balanced by forming similar polarity in poles of the half rings 2 and the poles of the propellers 3 facing each other.
