Clothes treatment apparatus

Abstract

A clothes treatment apparatus includes a housing, a tub provided inside the housing, a detergent supply device disposed below the tub and configured to supply a detergent to the tub, and a drainage device configured to discharge water from the tub to an outside of the housing or to the detergent supply device. The detergent supply device includes a first detergent box and a second detergent box, a first detergent pump configured to discharge a detergent from the first detergent box, a second detergent pump configured to discharge a detergent from the second detergent box, and a case guide connected to the first detergent pump and the second detergent pump. The case guide is configured to allow the detergent discharged from the first detergent box or the second detergent box and the water discharged from the drainage device to be mixed while passing through the case guide.

What is claimed is: 
     
         1 . A clothes treatment apparatus comprising:
 a housing;   a tub provided inside the housing;   a detergent supply device disposed below the tub and configured to supply a detergent to the tub; and   a drainage device comprising a drain pipe configured to discharge water from the tub to an outside of the housing or to the detergent supply device,   wherein the detergent supply device includes:
 a first detergent box and a second detergent box; 
 a first detergent pump configured to discharge a detergent from the first detergent box; 
 a second detergent pump configured to discharge a detergent from the second detergent box; and 
 a case guide connected to the first detergent pump and the second detergent pump, 
   wherein the case guide is configured to allow the detergent discharged from the first detergent box or the second detergent box and the water discharged from the drainage device to be mixed while passing through the case guide.   
     
     
         2 . The clothes treatment apparatus of  claim 1 , wherein the first detergent pump is configured to supply a detergent from the first detergent box to the case guide. 
     
     
         3 . The clothes treatment apparatus of  claim 1 , further comprising a third detergent box connectable to the second pump. 
     
     
         4 . The clothes treatment apparatus of  claim 3 , wherein the second detergent pump is configured to supply a detergent from the second detergent box or a detergent from the third detergent box to the case guide. 
     
     
         5 . The clothes treatment apparatus of  claim 1 , wherein the detergent supply device includes:
 an inlet port configured to introduce water discharged from the drainage device; and   an outlet port configured to discharge the water introduced through the inlet port,   wherein the case guide connects the inlet port to the outlet port.   
     
     
         6 . The clothes treatment apparatus of  claim 5 , further comprising: a circulation guide connecting the inlet port to the drainage device; and
 a detergent guide connecting the outlet port to the tub.   
     
     
         7 . The clothes treatment apparatus of  claim 1 , wherein the drainage device includes:
 a drain pump configured to discharge water from the tub to the outside of the housing; and   a circulation pump configured to discharge water from the tub to the detergent supply device.   
     
     
         8 . The clothes treatment apparatus of  claim 1 , wherein the detergent supply device is located below the tub in a direction of gravity. 
     
     
         9 . The clothes treatment apparatus of  claim 1 , further comprising a detergent case configured to accommodate at least a portion of the first detergent box and at least a portion of the second detergent portion,
 wherein the case guide is provided in the detergent case.   
     
     
         10 . The clothes treatment apparatus of  claim 1 , wherein the case guide includes:
 a first connection portion connected to the first detergent pump;   a second connection portion connected to the second detergent pump; and   an extension portion connecting the first connection portion to the second connection portion.   
     
     
         11 . The clothes treatment apparatus of  claim 1 , further comprising a controller including at least one processor, comprising processing circuitry, individually and/or collectively, configured to control the drainage device, the first detergent pump, and the second detergent pump based on an input. 
     
     
         12 . The clothes treatment apparatus of  claim 11 , wherein the controller is configured to control the first detergent pump to discharge the detergent from the first detergent box to the case guide based on an input for supplying the detergent from the first detergent box to the tub. 
     
     
         13 . The clothes treatment apparatus of  claim 11 , wherein the controller is configured to control the second detergent pump to discharge the detergent from the second detergent box or the third detergent box to the case guide based on an input for supplying the detergent from the second detergent box or the third detergent box to the tub. 
     
     
         14 . The clothes treatment apparatus of  claim 11 , wherein the controller is configured to control the drainage device to allow water in the tub to pass through the detergent supply device based on an input for supplying a detergent to the tub. 
     
     
         15 . The clothes treatment apparatus of  claim 1 , wherein the drainage device includes a filter configured to filter out foreign substances from water passing through the drainage device.
