Pump device for liquid detergent

Abstract

The present invention relates to a pump device for a liquid detergent, which reduces vibration and noise by inhibiting interference between parts during operation, thereby reducing damage to the parts. The pump device for a liquid detergent includes: a corrugated tube connected to a conveying tube unit from which the liquid detergent is discharged; a supply tube guiding the liquid detergent supplied through the corrugated tube to a tub; and a coupler connecting the corrugated tube and the supply tube and coupled to a base plate.

1 . A pump device for a liquid detergent, comprising:
 a corrugated tube connected to a conveying tube unit from which the liquid detergent is discharged;   a supply tube guiding the liquid detergent supplied through the corrugated tube to a tub; and   a coupler connecting the corrugated tube and the supply tube and coupled to a base plate.   
     
     
         2 . The pump device of  claim 1 , wherein the coupler comprises:
 an introduction hole portion coupled to the corrugated tube;   a connection hole portion coupled to the supply tube;   a main body connecting the introduction hole portion and the connection hole portion; and   a fixation portion formed on the main body and fixed to the base plate.   
     
     
         3 . The pump device of  claim 2 , wherein the introduction hole portion and the connection hole portion are integrated with the main body so as to be spaced from each other. 
     
     
         4 . The pump device of  claim 2 , wherein the fixation portion comprises a hook inserted into a groove portion of the base plate. 
     
     
         5 . The pump device of  claim 4 , wherein the coupler further comprises an elastic portion inhibiting the fixation portion from coming off from the base plate. 
     
     
         6 . The pump device of  claim 5 , wherein the elastic portion is arranged to be spaced upward from the fixation portion, and has both ends formed in a curved panel shape which is inclined downward. 
     
     
         7 . The pump device of  claim 6 , wherein when the fixation portion is inserted into the groove portion of the base plate and closely attached to the bottom surface of the base plate, both ends of the elastic portion are closely attached to the top surface of the base plate.
