Robot cleaner

Abstract

A robot cleaner is disclosed, which comprises a main body forming an external appearance, a water bucket unit provided in the main body, supplying water to a water mop, a driving wheel rotated by a rotational force of a driving motor provided in the main body, moving the main body, and a wiper module provided in the water bucket unit, wherein the wiper module is extended to front and rear directions of the driving wheel and formed to be protruded toward the floor where the main body drives.

1 . A robot cleaner comprising:
 a main body forming an external appearance;   a water bucket unit provided in the main body, supplying water to a water mop;   a driving wheel rotated by a rotational force of a driving motor provided in the main body, moving the main body; and   a wiper module provided in the water bucket unit,   wherein the wiper module is extended to front and rear directions of the driving wheel and formed to be protruded toward the floor where the main body drives.   
     
     
         2 . The robot cleaner of  claim 1 , wherein the wiper module includes a body coupled to the water bucket unit, and an arm extended from the body. 
     
     
         3 . The robot cleaner of  claim 2 , wherein the arm includes:
 a first arm extended toward the front direction of the driving wheel; and   a second arm extended toward the rear direction of the driving wheel,   wherein the first arm and the second arm are extended in their respective directions different from each other.   
     
     
         4 . The robot cleaner of  claim 2 , wherein the wiper module includes a wiper coupled to the arm. 
     
     
         5 . The robot cleaner of  claim 3 , wherein one end of the wiper is inclined to have a thin thickness. 
     
     
         6 . The robot cleaner of  claim 5 , wherein one end of the wiper is extended to contact the floor when the robot cleaner drives. 
     
     
         7 . The robot cleaner of  claim 5 , wherein one end of the wiper is extended to be spaced apart from the floor when the robot cleaner drives. 
     
     
         8 . The robot cleaner of  claim 1 , wherein the water bucket unit is provided with a guide forming a space, and the wiper module is inserted and coupled into the space. 
     
     
         9 . The robot cleaner of  claim 8 , wherein the guide is arranged at a side of the water bucket unit, and the space is provided to open the water bucket unit toward the floor where the robot cleaner drives. 
     
     
         10 . The robot cleaner of  claim 1 , wherein the water bucket unit is provided with a hook, and a coupling groove into which the hook is inserted and coupled is formed at a lower portion of the main body. 
     
     
         11 . The robot cleaner of  claim 10 , wherein the hook is formed to be protruded from the water bucket unit toward a direction where the water bucket unit is coupled to the main body. 
     
     
         12 . The robot cleaner of  claim 1 , wherein the water bucket unit includes a water supply unit supplying water to a water mop, and the water supply unit includes a water transfer member absorbing water and transferring the absorbed water to the water mop and a shielding member in which the water transfer member is provided. 
     
     
         13 . The robot cleaner of  claim 12 , wherein the water supply unit is arranged on a lower surface of the water bucket unit. 
     
     
         14 . The robot cleaner of  claim 1 , wherein the water bucket unit is provided with a binding rib, the main body is provided with a binding portion into which the binding rib is inserted and fixed, and the binding portion is arranged in a rear direction of the main body and arranged at the center of a horizontal width of the main body. 
     
     
         15 . The robot cleaner of  claim 1 , wherein an air inflow unit for controlling an air pressure of a space filled with water is formed on an upper surface of the water bucket unit.
