Dish washer

Abstract

A dish washer comprising: a tub forming a washing chamber; a plurality of spray rotors spraying water into the washing chamber; and a sump assembly. The sump assembly comprises: a sum housing including a distribution chamber to accommodate water which is provided to the plurality of spray rotors; a distribution disk, positionable in the distribution chamber, to provide the water accommodated in the distribution chamber to at least one of the plurality of spray rotors; a distribution motor generating rotational force to rotate the distribution disk; and a connecting shaft to transmit the rotational force of the distribution motor to the distribution disk and guide water leaking from the distribution chamber to outside of the connecting shaft.

1 . A dish washer comprising:
 a tub forming a washing room;   a plurality of spray rotors configured to spray water to the washing room; and
 a sump assembly including: a sump housing including a distribution chamber to accommodate the water that is to be provided to the plurality of spray rotors; 
 a distribution disk, positionable in the distribution chamber, and configured to provide the water that is accommodated in the distribution chamber to at least one of the plurality of spray rotors; 
 a distribution motor configured to generate a rotational force to rotate the distribution disk; and 
 a connecting shaft, positionable coaxially with a motor shaft of the distribution motor, and configured to transfer the rotational force of the distribution motor to the distribution disk, the connecting shaft including a guide body configured to guide water leaking from the distribution chamber to outside of the connecting shaft. 
   
     
     
         2 . The dish washer of  claim 1 , wherein
 the sump housing further comprises:
 a chamber hole through to the distribution chamber, wherein a part of the connecting shaft passes through the chamber hole; and 
 a flange, positionable to correspond to the chamber hole, and extending along a longitudinal direction of the connecting shaft, the flange forming a guide flow path which is spaced from a circumferential surface of the connecting shaft and along which the water leaking from the distribution chamber flows. 
   
     
     
         3 . The dish washer of  claim 2 , wherein
 the guide flow path is a first guide flow path, and   the guide body of the connecting shaft comprises:
 a second guide flow path along which water discharged from the first guide flow path flows, and 
 a penetrating hole through which the water from the second guide flow path flows to the outside of the connecting shaft. 
   
     
     
         4 . The dish washer of  claim 1 , wherein
 the sump assembly further comprises a holder in which the distribution motor is mountable, and   the holder comprises a guide hole configured to guide water leaking from the connecting shaft to outside of the sump assembly to prevent the water from flowing to the distribution motor while the distribution motor mounted to the holder.   
     
     
         5 . The dish washer of  claim 4 , wherein
 the holder further comprises:
 an insertion hole in which the motor shaft of the distribution motor is insertable so that while the motor shaft is inserted in the insertion hole, the motor shaft protrudes toward the connecting shaft, and 
 a first protrusion extending upward to correspond to the insertion hole, and 
   the connecting shaft further comprises a second protrusion extending downward from a side of the connecting shaft adjacent to the distribution motor and covering the first protrusion.   
     
     
         6 . The dish washer of  claim 5 , wherein
 an internal diameter of the second protrusion is greater than an external diameter of the first protrusion.   
     
     
         7 . The dish washer of  claim 3 , wherein
 the connecting shaft further comprises a side guide portion, positioned below the flange, and configured to guide water in the first guide flow path to the second guide flow path.   
     
     
         8 . The dish washer of  claim 7 , wherein
 an internal diameter of the side guide portion is greater than an internal diameter of the flange.   
     
     
         9 . The dish washer of  claim 7 , wherein
 the side guide portion includes a portion in a shape inclined downward toward the second guide flow path.   
     
     
         10 . The dish washer of  claim 3 , wherein
 the connecting shaft further comprises a shaft body extending along a vertical direction, wherein an end of the shaft body is coupled to the distribution motor and another end of the shaft body is coupled to the distribution disk, and   the guide body is positioned to a radially outer side from the shaft body.   
     
     
         11 . The dish washer of  claim 10 , wherein
 the guide body comprises:
 a bottom portion, extending radially from a side of the shaft body adjacent to the distribution motor, and including the penetrating hole; and 
 a side wall portion surrounding at least a part of the shaft body and extending toward the flange from the bottom portion. 
   
     
     
         12 . The dish washer of  claim 1 , wherein
 the sump assembly further comprises a switch mountable on a holder and configured to detect a rotation position of the connecting shaft.   
     
     
         13 . The dish washer of  claim 12 , wherein
 the switch is configured to be rotatable between a first position at which the switch is couplable to the holder and a second position to which the switch has rotated from the first position while being coupled to the holder and at which the switch is in contact with the connecting shaft.   
     
     
         14 . The dish washer of  claim 13 , wherein
 the holder further comprises a separation prevention protrusion by which a side of the switch is caught to prevent the switch from departing from the second position.   
     
     
         15 . The dish washer of  claim 14 , wherein
 the holder further comprises an elastic member configured to press another side of the switch such that no gap is between a side of the switch and the separation prevention protrusion.
