         5 . The washing machine of  claim 1 , further comprising
 a drum disposed inside the tub, configured to load laundry therein and rotated with respect to the tub,   wherein the second water supply tube is disposed to drop the laundry water to a space between the tub and the drum.   
     
     
         6 . The washing machine of  claim 5 , wherein the second water supply tube is disposed to drop the laundry water on an inner wall of the tub. 
     
     
         7 . The washing machine of  claim 5 , further comprising:
 a supply part disposed at the tub to guide the laundry water from the second water supply tube to an inside of the tub;   a water storing part disposed inside the supply part, spaced apart from the supply part by a predetermined distance to form a first back-flow prevention path, and configured to store a part of water supplied from the second water supply tube; and   a water guide installed inside the second water supply tube, configured to guide the laundry water from the second water supply tube to the tub side, a bottom end of which is inserted into an inside of the water storing art, and spaced apart from the water storing part by a predetermined distance to form a second back-flow prevention path,   wherein the laundry water supplied from the second water supply tube is stored in the water storing part and then passes through the second back-flow prevention path and the first back-flow prevention path to flow into the tub.   
     
     
         8 . The washing machine of  claim 7 , wherein a bottom end of the water guide is soaked in water of the water storing part. 
     
     
         9 . The washing machine of  claim 7 , wherein a lower side of the water storing part is disposed at a curved surface forming the tub. 
     
     
         10 . The washing machine of  claim 7 , wherein a lower side of the water storing part has a curved surface when viewed from a front of the washing machine. 
     
     
         11 . The washing machine of  claim 1 , wherein the detergent box further comprises:
 a first supply part connected with the first water supply tube; and   a second supply part connected with the second water supply tube.   
     
     
         12 . The washing machine of  claim 11 , further comprising:
 a flow-path separating partition disposed inside the detergent box,   wherein the flow-path separating partition separately flows the laundry water from the water supply unit to the first supply part and the second supply part.   
     
     
         13 . The washing machine of  claim 12 , wherein the detergent box further comprises:
 a dispenser installed at the cabinet and formed therein with the first supply part and the second supply part; and   a drawer movably installed at the dispenser,   wherein the flow-path separating partition is disposed at the dispenser.   
     
     
         14 . The washing machine of  claim 13 , wherein the flow-path separating partition divides an inside of the dispenser into a first space and a second space,
 the first space is connected with the first supply part and the second space is connected with the second supply part.   
     
     
         15 . The washing machine of  claim 14 , further comprising
 a swirl partition disposed at the first space,   wherein the swirl partition generates a torque in laundry water flowing through the first supply part.   
     
     
         16 . The washing machine of  claim 15 , wherein the first supply part is vertically formed, and the swirl partition is disposed at a top side of the first supply part.
