Introduced to clothes washing and drying machines

Abstract

Improvements introduced to clothes and drying machines, according to which the application of the innovative circumscribed ring-motor ( 1 ) is established, and now also the flat ring-motor ( 6 ) and its respective variations, in mini washing machines and mini-clothes dryers. The circumscribed ring-motor ( 1 ) and the flat ring-motor ( 6 ) properly encapsulated and protected from contact with water, considerably substitute various normal mechanical components necessary for the movement of the tub ( 20 ) and washing such as belts, pulleys, gears and gearbox. The constructive simplicity of the motor permits pat of it to be coupled on the surface of the washing chamber, tub ( 20 ) on the lid ( 21 ) or on the outside botton part of the machine, generating the alternate circular movement of the washing chamber, tub ( 20 ) directly or indirectly without the assitance of secondary parts, thus permiting a vast number of variations and allowing the tube ( 20 ) to be removed at the end of the washing process and serve to transport the clothing.

In turn, this hole has a lodged bearing ( 35 ), which surrounds and supports this axis ( 34 ), thus guaranteeing the deriving movement of the rotor ring ( 2 ), further to the mounting and alignment of the entire assembly, which in turn is closed by a side lid ( 36 ).  
   
   
       55 . “IMPROVEMENTS INTRODUCED TO CLOTHES WASHING AND DRYING MACHINES”, according to  claim 3 , characterized by the fact that the flat ring-motor ( 6 ) is totally isolated as an independent and autonomous component to be coupled to the assembly (tank and tub) for specific tasks such as washing and spinning or drying, now called an agitator.  
   
   
       56 . “IMPROVEMENTS INTRODUCED TO CLOTHES WASHING AND DRYING MACHINES”, according to  claim 55 , characterized by establishing that the agitator ( 37 ) shall consist of a flat ring-motor ( 6 ), with the stator ring ( 9 ) mounted on the front of a disc ( 38 ), with a hole ( 39 ) in its center. This disc totally faces the rotor ring ( 7 ) in parallel, and this ring is coupled on the front of another disc ( 40 ), which transmits the circular or alternate movement of the rotor ( 7 ), through an axis ( 34 ) positioned in the center of the disc ( 43 ). This axis overreaches the central hole ( 39 ) of the disc ( 38 ). In turn, this hole has a lodged bearing ( 35 ), which surrounds and supports this axis ( 34 ), thus guaranteeing the deriving movement of the rotor ring ( 7 ), further to the mounting and alignment of the entire assembly, which in turn is closed by a lid ( 36 ).  
   
   
       57 . “IMPROVEMENTS INTRODUCED TO CLOTHES WASHING AND DRYING MACHINES”, according to claims  1  or  3 , characterized by the fact that circumscribed ring-motors ( 1 ) and flat ring-motors ( 6 ) are also applied in washing machines that operate by simple tumbling with horizontal cylindrical tanks.  
   
   
       58 . “IMPROVEMENTS INTRODUCED TO CLOTHES WASHING AND DRYING MACHINES”, according to claims  1  or  3 , characterized by the fact that circumscribed ring-motors ( 1 ) and flat ring-motors ( 6 ) are also applied in washing machines that operate by agitation with vertical cylindrical tanks.  
   
   
       59 . “IMPROVEMENTS INTRODUCED TO CLOTHES WASHING AND DRYING MACHINES”, according to claims  11 , or  15 , or  19 , or  20 , or  23 , or  27  or  28 , characterized by the fact that the tub ( 20 ) can be optionally removed from the washing machine at the end of the washing process, together with the clothing.
