Washing machine

Abstract

A novel and excellently configured washing machine wherein a washing-tub can be rotated by centering on either two rotating-shafts oriented in different directions. A washing machine is provided with an outer-tub ( 4 ), a rotatable-support-body ( 7 ), an toroidal-rail-part ( 18 ) which is rotatable coaxial with a support-body-shaft ( 8 ) which is the rotating shaft for the support-body ( 7 ), and a washing-tub ( 13 ) which is mounted in the inside of the support-body ( 7 ) and is rotatably connected to the support-body ( 7 ) by washing-tub-shafts ( 14 ). Rolling-parts ( 16, 17 ) which rotate when the washing-tub ( 13 ) rotates using the washing-tub-shafts ( 14 ) as the rotating shafts are formed on the exterior surface of the washing-tub ( 13 ). The rolling-parts ( 16, 17 ) touches the toroidal-rail-part ( 18 ) so as to be able to transmit the rotating force. The support-body-shaft ( 8 ) is a shaft oriented in a different direction from the washing-tub-shafts ( 14 ).

 when by the said motor the said outer-shaft does not rotate and the said inner-shaft rotates, the said support-body does not rotate, the said washing-tub rotates by centering on the said washing-tub-shaft for the rotating force of the said toroidal-rail-part to transmit to the said rolling-part; 
 when by the said motor the said outer-shaft and the said inner-shaft was rotated to the same rotating direction with the same rotating speed, the said washing-tub does not rotate by centering on the said washing-tub-shaft and rotates together with the said support-body by centering on the said support-body-shaft. 
 
     
     
         7 . The washing machine according to  claim 1 , wherein the said rolling-part is a rolling-wheel that is another body of the said washing-tub and is on the said washing-tub-shaft. 
     
     
         8 . The washing machine according to  claim 7 , wherein:
 the external form of the said washing-tub is spheroidal;   the said rolling-wheel is equipped adjacently outside the surface of the external form of the said washing-tub.   
     
     
         9 . The washing machine according to  claim 7  or  claim 8  comprising:
 a coaxial-two-axis-structure that has a outer-shaft and has a inner-shaft that was inserted in the inside of the said outer-shaft; 
 a motor that drives the said coaxial-two-axis-structure, 
 and wherein: 
 the said inner-shaft is connected to the said support-body, and a center axis of the said inner-shaft accords to the said support-body-shaft; 
 the said outer-shaft is connected with the said toroidal-rail-part; 
 when by the said motor the said outer-shaft does not rotate and the said inner-shaft rotates, the said support-body rotates by centering on the said support-body-shaft, the said rolling-wheel rotates by centering on the said support-body-shaft while osculating to the said toroidal-rail-part, thereby the said rolling-wheel rotates by centering on the said washing-tub-shaft, the said washing-tub too rotates by centering on the said washing-tub-shaft; 
 when by the said motor the said outer-shaft and the inner-shaft is rotated to the same rotating direction with the same rotating speed, the said support-body rotates by centering on the said support-body-shaft, the said washing-tub does not rotate by centering on the said washing-tub-shaft and rotates together with the said support-body by centering on the said support-body-shaft. 
 
     
     
         10 . The washing machine according to either one of claim from  2  to  5  or  7  or  8 , comprising:
