Laundry treating apparatus

Abstract

A laundry treating apparatus includes a cabinet, an inner casing disposed inside the cabinet and providing an accommodating space for laundry, a machine room disposed under the inner casing to circulate air inside the inner casing, a supply hole defined through a bottom surface of the inner casing such that the inner casing is in communication with the machine room and receives air thereinto, a discharge hole defined to be spaced apart from the supply hole and defined through the bottom surface of the inner casing such that the inner casing is in communication with the machine room and discharges air to the machine room, and a guide rib provided to partition the supply hole. The guide rib is configured to include guide ribs spaced apart from each other, and each guide rib is configured to have a different inclination from a top surface of the inner casing.

What is claimed is: 
     
         1 . A laundry treating apparatus comprising:
 a cabinet;   an inner casing disposed inside the cabinet, including a laundry inlet defined in a front surface thereof where laundry is inserted, and providing an accommodating space where the laundry is mounted;   a machine room disposed under the inner casing to circulate air inside the inner casing;   a supply hole defined through a bottom surface of the inner casing such that the inner casing is in communication with the machine room and receives air thereinto;   a discharge hole defined to be spaced apart from the supply hole and defined through the bottom surface of the inner casing such that the inner casing is in communication with the machine room and discharges air to the machine room; and   a guide rib provided to partition the supply hole,   wherein the guide rib is configured to include a plurality of guide ribs spaced apart from each other, and each guide rib is configured to have a different inclination from a top surface of the inner casing.   
     
     
         2 . The laundry treating apparatus of  claim 1 , wherein the guide rib is provided to partition the supply hole in the front and rear directions and is configured to include:
 a vertical guide rib disposed to be perpendicular to the top surface of the inner casing and supplying air vertically; and   an inclined guide rib disposed to be spaced apart from the vertical guide rib and inclined such that a fixed end thereof is configured to be located closer to the discharge hole than a free end thereof to guide a flow channel of air to be formed inclined.   
     
     
         3 . The laundry treating apparatus of  claim 2 , wherein the supply hole is defined in a front side and the discharge hole is defined in a rear side. 
     
     
         4 . The laundry treating apparatus of  claim 2 , wherein the inclined guide rib is configured to be disposed closer to the discharge hole than the vertical guide rib. 
     
     
         5 . The laundry treating apparatus of  claim 2 , wherein the guide rib is configured to include a partitioning guide rib partitioning the supply hole into a first area and a second area located closer to the discharge hole than the first area,
 wherein a free end of the partitioning guide rib is configured to be positioned at a lower vertical level than the free end of the inclined guide rib and a free end of the vertical guide rib.   
     
     
         6 . The laundry treating apparatus of  claim 5 , wherein the vertical guide rib is configured to be disposed in the first area,
 wherein the inclined guide rib is configured to be disposed in the second area.   
     
     
         7 . The laundry treating apparatus of  claim 5 , wherein the partitioning guide rib is configured to be disposed in parallel with the vertical guide rib. 
     
     
         8 . The laundry treating apparatus of  claim 6 , wherein the inclined guide rib is configured to include multiple inclined guide ribs. 
     
     
         9 . The laundry treating apparatus of  claim 8 , wherein the multiple inclined guide ribs are configured to be arranged such that respective fixed ends thereof are spaced apart from each other at a regular spacing. 
     
     
         10 . The laundry treating apparatus of  claim 9 , wherein the multiple inclined guide ribs are configured to be arranged such that a distance between free ends of inclined guide ribs adjacent to each other decreases in a direction closer to the discharge hole. 
     
     
         11 . The laundry treating apparatus of  claim 5 , wherein the guide rib is configured to include a bent guide rib connecting both side surfaces of the supply hole to each other, extending in parallel with the inclined guide rib toward the machine room, and then extending parallel to the vertical guide rib. 
     
     
         12 . The laundry treating apparatus of  claim 11 , wherein a free end of the bent guide rib is configured to be located at a vertical level equal to or higher than the vertical level of the free end of the partitioning guide rib and lower than the vertical level of the free end of the inclined guide rib. 
     
     
         13 . The laundry treating apparatus of  claim 12 , wherein the bent guide rib is configured to be disposed in the second area. 
     
     
         14 . The laundry treating apparatus of  claim 11 , wherein the bent guide rib is configured to include multiple bent guide ribs. 
     
     
         15 . The laundry treating apparatus of  claim 1 , wherein an inclined guide rib is configured to include a curved surface on at least one of a front surface and a rear surface thereof. 
     
     
         16 . The laundry treating apparatus of  claim 2 , wherein the vertical guide rib is configured to include a curved surface on at least one of a front surface and a rear surface thereof. 
     
     
         17 . The laundry treating apparatus of  claim 5 , wherein the partitioning guide rib is configured to include a curved surface on at least one of a front surface and a rear surface thereof. 
     
     
         18 . The laundry treating apparatus of  claim 11 , wherein the bent guide rib is configured to include a curved surface on at least one of a front surface and a rear surface thereof. 
     
     
         19 . The laundry treating apparatus of  claim 1 , further comprising a plate forming at least a portion of the bottom surface of the inner casing and including the supply hole defined therein,
 wherein the plate is configured to be constructed to be detachable from the bottom surface.   
     
     
         20 . The laundry treating apparatus of  claim 19 , wherein the plate is configured to be inclined such that one side adjacent to the discharge hole is configured to be located at a lower vertical level than the other side facing the one side.
