Washing machine drum baffle and washing machine therewith

Abstract

The invention relates to a drum baffle and a washing machine having the same. The drum baffle includes a sheath and a bottom plate. The sheath and the bottom plate form a cavity having a hollow structure. The drum baffle is made by injection molding using one or more polymer adsorption materials, which may be used as a washing medium. The cavity of the drum baffle is internally filled with solid particles. The drum baffle includes a plurality of holes defined for communicating with the cavity of the drum baffle and an inner space of the inner drum of the washing machine to allow washing water to flow through. The drum baffle assists laundry to be rolled inside the inner drum, where the drum baffle and the solid particles inside adsorb and absorb soil in the laundry so as to achieve better washing results.

 a sheath; and   a bottom plate,   wherein the sheath and the bottom plate form a hollow structure having a cavity and a plurality of holes defined thereon, the cavity is internally filled with solid particles as a washing medium, and the plurality of holes is adapted to communicate the cavity with an inner space of the inner drum of the washing machine to allow washing water to flow through.   
     
     
         2 . The drum baffle according to  claim 1 , being made by injection molding of one or more polymer adsorption materials that are used as the washing medium. 
     
     
         3 . The drum baffle according to  claim 1 , wherein the sheath comprises two end walls, two side walls connected between the two end walls, and a top wall connected between the two end walls and between the two side walls. 
     
     
         4 . The drum baffle according to  claim 3 , wherein the plurality of holes is defined at least on the top wall of the sheath. 
     
     
         5 . The drum baffle according to  claim 3 , wherein the bottom plate is detachably or rotatable-openably connected to a bottom of the sheath. 
     
     
         6 . The drum baffle according to  claim 1 , wherein the plurality of holes is defined on the bottom plate. 
     
     
         7 . The drum baffle according to  claim 1 , further comprising one or more reinforcement bars for strengthening and supporting the drum baffle. 
     
     
         8 . The drum baffle according to  claim 1 , wherein a side edge extends from each of two bottom sides of the drum baffle and includes one or more mounting holes for fastening the drum baffle onto the inner wall of the inner drum of the washing machine. 
     
     
         9 . The drum baffle according  claim 1 , further comprising a plurality of protrusions formed outwardly on an outer surface of the sheath, wherein the plurality of protrusions is integrally formed on the sheath. 
     
     
         10 . The drum baffle according  claim 1 , wherein the solid particles are made of one or more polymer adsorption materials. 
     
     
         11 . A washing machine, comprising:
 an inner drum having an inner wall; and   one or more drum baffles disposed on the inner wall of the inner drum, each drum baffle being recited in  claim 1 .   
     
     
         12 . A drum baffle disposed on an inner wall of an inner drum of a washing machine, comprising:
 a structure being made by injection molding of one or more polymer adsorption materials that are used as a washing medium.   
     
     
         13 . The drum baffle according to  claim 12 , wherein the structure is a hollow structure. 
     
     
         14 . The drum baffle according to  claim 13 , wherein the hollow structure comprises a sheath having two end walls, two side walls connected between the two end walls, and a top wall connected between the two end walls and between the two side walls. 
     
     
         15 . The drum baffle according to  claim 14 , wherein a plurality of holes is defined at least on the top wall of the sheath for allowing washing water to flow through. 
     
     
         16 . The drum baffle according to  claim 13 , further comprising one or more reinforcement bars disposed inside the hollow structure for strengthening and supporting the drum baffle. 
     
     
         17 . The drum baffle according to  claim 12 , wherein a side edge extends from each of two bottom sides of the structure and includes one or more mounting holes for fastening the structure onto the inner wall of the inner drum of the washing machine. 
     
     
         18 . The drum baffle according  claim 12 , further comprising a plurality of protrusions formed outwardly on an outer surface of the structure. 
     
     
         19 . The drum baffle according  claim 18 , wherein the plurality of protrusions is integrally formed on the structure. 
     
     
         20 . A washing machine, comprising:
 an inner drum having an inner wall; and   one or more drum baffles disposed on the inner wall of the inner drum, each drum baffle being recited in  claim 12 .
