Washing machine

Abstract

The present disclosure discloses a washing machine, including a washing drum, wherein the washing drum is a water accommodating drum during washing; a balance ring, arranged above the washing drum; and a sealing structure, configured to prevent water from overflowing from a space between the washing drum and the balance ring. The washing drum disclosed by the present disclosure achieves an expansion effect; at the same time, the sealing structure is arranged between the washing drum and the balance ring to prevent that the water overflows out of the washing drum from the space between the washing drum and the balance ring, and after a long time, the water may splash to corrode a washing machine case body or other components, or cause a short circuit.

         3 . The washing machine according to  claim 2 , wherein the mounting part comprises an annular bulge protruding radially from a side wall of the balance ring; the fitting part comprises an annular groove matched with the annular bulge; and the sealing structure is arranged between the annular bulge and the annular groove. 
     
     
         4 . The washing machine according to  claim 3 , wherein the washing drum comprises a water retaining part arranged below the annular groove and the water retaining part is configured to narrow a gap between the washing drum and the balance ring to retain water;
 a water collection cavity is formed by the washing drum, the water retaining part and the balance ring; and the water collection cavity is configured to collect rising water.   
     
     
         5 . The washing machine according to  claim 1 , wherein the washing machine further comprises a drainage structure; the drainage structure comprises a dewatering passage which is arranged on an outer wall of the washing drum, communicated with an inside of the washing drum and is configured to drain water thrown out by the washing drum; and a water inlet end of the dewatering passage is arranged on the upper end of the washing drum. 
     
     
         6 . The washing machine according to  claim 4 , wherein the water inlet end is arranged on the water collection cavity below the water retaining part. 
     
     
         7 . The washing machine according to  claim 4 , wherein the water retaining part is a necking part formed by recessed from an outer side to an inner side of the washing drum. 
     
     
         8 . The washing machine according to  claim 7 , wherein an upper end of the necking part extends towards a periphery to form a supporting part for supporting the mounting part of the balance ring; the supporting part extends upwards to form an accommodating part surrounding the mounting part of the balance ring; an upper end of the accommodating part is inwards flanged to form a fixing part for fixing the mounting part of the balance ring. 
     
     
         9 . The washing machine according to  claim 8 , wherein the supporting part, the accommodating part and the fixing part together form the annular groove with an inward opening. 
     
     
         10 . The washing machine according to  claim 1 , wherein the sealing structure is an annular sealing ring which is squeezed between the washing drum and the balance ring and has a deformation. 
     
     
         11 . The washing machine according to  claim 2 , wherein the washing machine further comprises a drainage structure; the drainage structure comprises a dewatering passage which is arranged on an outer wall of the washing drum, communicated with an inside of the washing drum and is configured to drain water thrown out by the washing drum; and a water inlet end of the dewatering passage is arranged on the upper end of the washing drum. 
     
     
         12 . The washing machine according to  claim 3 , wherein the washing machine further comprises a drainage structure; the drainage structure comprises a dewatering passage which is arranged on an outer wall of the washing drum, communicated with an inside of the washing drum and is configured to drain water thrown out by the washing drum; and a water inlet end of the dewatering passage is arranged on the upper end of the washing drum. 
     
     
         13 . The washing machine according to  claim 8 , wherein the sealing structure is arranged between the fixing part and the annular bulge. 
     
     
         14 . The washing machine according to  claim 8 , wherein the sealing structure is of a flat structure; a friction coefficient of fitting surfaces between the sealing structure and the annular bulge is larger than friction coefficients of between other surfaces of the sealing structure and the annular bulge. 
     
     
         15 . The washing machine according to  claim 9 , wherein all corners formed by the necking part and the annular groove are rounded corners.
