Washing machine having detergent supply device

Abstract

A washing machine having a detergent supply device for mixing detergent, filled in a detergent container, with wash water, and supplying the mixed detergent and wash water into a washing tub. The detergent supply device includes a housing, a detergent container, and water supply chambers. The housing includes a plurality of inlets connected with respective water supply pipes, and an outlet connected with a washing tub. The detergent container is detachably inserted in the housing and includes a plurality of detergent receiving chambers. The water supply chambers include a plurality of flow channels, and one of the flow channel is adapted to supply wash water, supplied from the inlets, into the detergent receiving chambers while adjusting the pressure of the wash water within a predetermined range.

1 . A washing machine having a detergent supply device, the detergent supply device comprising: 
 a housing including a plurality of inlets connected with respective water supply pipes, and an outlet connected with a washing tub;    a detergent container detachably inserted in the housing and includes a plurality of detergent receiving chambers; and    water supply chambers each including a flow channel to adjust a pressure of wash water supplied from the inlets, within a predetermined range, and to supply the wash water into the detergent receiving chambers.    
   
   
       2 . The washing machine according to  claim 1 , wherein one of the flow channels comprises pressure-adjustment holes to discharge the wash water, having a flow rate corresponding to the pressure of the wash water passing through the flow channel, from the flow channel.  
   
   
       3 . The washing machine according to  claim 2 , wherein the water supply chambers are positioned to correspond to the respective detergent receiving chambers; and 
 the wash water discharged from the pressure-adjustment holes formed at the respective flow channel to supply the wash water into one of the detergent receiving chambers, is supplied into another one of the detergent receiving chambers.    
   
   
       4 . The washing machine according to  claim 1 , wherein the flow channels communicate with a plurality of the water supply pipes arranged such that water supply directions thereof intersect each other; and 
 the flow channels supply the wash water simultaneously injected from the water supply pipes and converged at a predetermined position, into the water supply chambers.    
   
   
       5 . The washing machine according to  claim 4 , wherein one end of the flow channels comprises a flow channel widening portion for supplying a part of the converged wash water, exceeding a predetermined flow rate, into the water supply chambers.  
   
   
       6 . The washing machine according to  claim 1 , wherein the water supply chambers are positioned in an upper portion of the housing, and the detergent container is detachably inserted in a lower portion of the housing.  
   
   
       7 . The washing machine according to  claim 6 , wherein the water supply chambers are positioned above the detergent container to correspond to the respective detergent receiving chambers.  
   
   
       8 . The washing machine according to  claim 4 , further comprising a flow channel branching portion positioned at an intersection of the water supply directions.  
   
   
       9 . A washing machine having a detergent supply device, the detergent supply device comprising: 
 a housing including an upper and a lower portion coupled with each other and a plurality of inlets connected with respective water supply pipes;    a detergent container including detergent receiving chambers, to be slidably inserted into the lower portion and to receive detergent therein; and    water supply channels positioned in the upper portion and including flow channels to supply water into the detergent receiving chambers, wherein one of the flow channels includes pressure-adjustment holes to adjust a pressure of the water received from the water supply pipes at a predetermined pressure range.
