Water storage tank for washing machine and washing machine

Abstract

Provided is a water storage tank for a washing machine. The water storage tank for the washing machine includes: a tank body configured in a housing of the washing machine, and having a water flowing portion which is internally formed into a tubular shape and constitutes a continuous flow path surface and an external surface portion that constitutes a flexible external surface; a water injecting port arranged at one end of the tank body and configured to inject water, as washing drum drainage water, discharged from a washing drum to the tank body; and a water outtake port arranged at another end of the tank body and capable of recirculating the water injected into the tank body into the washing drum.

What is claimed is: 
     
         1 . A water storage tank for a washing machine, comprising:
 a tank body configured in a housing of the washing machine, and having a water flowing portion which is internally formed into a tubular shape and constitutes a continuous flow path surface and an external surface portion that constitutes a flexible external surface;   a water injecting port arranged at one end of the tank body and configured to inject washing drum drainage water discharged from a washing drum to the tank body; and   a water outtake port arranged at another end of the tank body and capable of recirculating the washing drum drainage water injected into the tank body into the washing drum.   
     
     
         2 . The water storage tank for the washing machine according to  claim 1 , wherein
 the external surface portion is formed into a linear shape having flexibility; and   wherein the water flowing portion comprises the flow path surface arranged on an internal surface of the external surface portion and formed into a tubular shape.   
     
     
         3 . The water storage tank for the washing machine according to  claim 1 , wherein
 a profile of the tank body is formed into a roughly plate shape.   
     
     
         4 . The water storage tank for the washing machine according to  claim 1 , wherein
 a profile of the tank body is formed into a roughly annular shape in which a mechanism arrangement space is formed at a center of the roughly annular shape.   
     
     
         5 . A washing machine, comprising a water storage tank for the washing machine, wherein the water storage tank for the washing machine comprises:
 a tank body configured in a housing of the washing machine, and having a water flowing portion which is internally formed into a tubular shape and constitutes a continuous flow path surface and an external surface portion that constitutes a flexible external surface;   a water injecting port arranged at one end of the tank body and configured to inject washing drum drainage water discharged from a washing drum to the tank body; and   a water outtake port arranged at another end of the tank body and capable of recirculating the washing drum drainage water injected into the tank body into the washing drum.   
     
     
         6 . The water storage tank for the washing machine according to  claim 2 , wherein
 a profile of the tank body is formed into a roughly plate shape.   
     
     
         7 . The water storage tank for the washing machine according to  claim 2 , wherein
 a profile of the tank body is formed into a roughly annular shape in which a mechanism arrangement space is formed at a center of the roughly annular shape.
