Washing machine

Abstract

A washing machine is described. The washing machine described comprises; a tub, a drum placed the tub therein, a permanent magnet placed on the drum and a stator interacting with the permanent magnet to generate a rotary power to the drum.

1 . A washing machine comprising; 
 a tub;    a drum installed inside of the tub;    a permanent magnet installed on the drum; and    a stator interacting with the permanent magnet to generate a rotary power to the drum.    
   
   
       2 . A washing machine according to  claim 1 , wherein the stator is installed on the tub.  
   
   
       3 . A washing machine according to  claim 1 , wherein the stator is water-proof.  
   
   
       4 . A washing machine according to  claim 1 , wherein the permanent magnet and the stator interacts in the radial direction of the drum.  
   
   
       5 . A washing machine according to  claim 1 , wherein the permanent magnet and the stator interacts in the shaft direction of the drum.  
   
   
       6 . A washing machine according to  claim 1 , wherein the permanent magnet is in a close loop form.  
   
   
       7 . A washing machine according to  claim 1 , wherein a groove portion is formed on the drum, and the permanent magnet is placed therein.  
   
   
       8 . A washing machine according to  claim 7 , wherein the whole of the permanent magnet is placed inside of the groove portion.  
   
   
       9 . A washing machine comprising; 
 a tub accommodating a washing water therein,    a drum installed inside of the tub,    a permanent magnet installed on the drum, and    a stator containing a winding part and winding coil wound around the winding part, interacting with the permanent magnet to generate a rotary power to the drum.    
   
   
       10 . A washing machine according to  claim 9 , wherein the permanent magnet is placed to face on an end of the winding part.  
   
   
       11 . A washing machine according to  claim 9 , wherein the permanent magnet is formed on the circumference of a predetermined radius in the drum.  
   
   
       12 . A washing machine according to  claim 9 , wherein the winding part is placed on the shaft direction of the tub.  
   
   
       13 . A washing machine according to  claim 9 , wherein the winding part is placed on the radius direction of the tub.  
   
   
       14 . A washing machine according to  claim 9 , wherein the end of the winding part is exposed to the part facing the permanent magnet of the tub.  
   
   
       15 . A washing machine according to  claim 9 , wherein a groove portion having a predetermined depth, is formed on the drum, and the permanent magnet is placed therein.  
   
   
       16 . A washing machine according to  claim 9 , wherein the winding coil is water-proof.  
   
   
       17 . A washing machine according to  claim 9 , wherein the stator further comprises a frame extending the winding part therefrom.  
   
   
       18 . A washing machine comprising; 
 a drum;    a groove formed in the drum;    a permanent magnet installed in the groove portion; and,    a stator interacting with the permanent magnet to generate a rotary power to the drum.    
   
   
       19 . A washing machine according to  claim 18 , wherein the groove portion is opened to the direction of the stator.  
   
   
       20 . A washing machine according to  claim 18 , wherein the groove portion is formed at a predetermined depth to place the whole of the permanent magnet therein.
