Wet mop module of cleaner

Abstract

The present disclosure relates to a wet duster module of a cleaner and relates to a wet duster module of a cleaner, which includes a diffuser having an inlet connected to a heat generator and an outlet disposed adjacent to a duster, wherein the diffuser includes a diffuser connection pipe formed at the inlet and connected to the heat generator and a diffuser nozzle formed at the outlet and disposed outward in a radial direction of a rotational cleaning part, and thus steam at the same temperature uniformly reaches a wide region of the duster.

         3 . The wet duster module of the cleaner of  claim 2 , wherein the diffuser extends along a virtual circle, and a center of the circle is disposed on a rotational axis of the rotational cleaning part. 
     
     
         4 . The wet duster module of the cleaner of  claim 2 , wherein the diffuser is formed in an arc shape. 
     
     
         5 . The wet duster module of the cleaner of  claim 4 , wherein the diffuser is disposed inside the rotational axis of the duster. 
     
     
         6 . The wet duster module of the cleaner of  claim 2 , wherein the diffuser is formed in a ring shape. 
     
     
         7 . The wet duster module of the cleaner of  claim 1 , wherein assuming a virtual reference line passing through the module housing,
 a plurality of the rotational cleaning parts are disposed symmetrically with respect to the reference line, and   the diffusers are disposed symmetrically with respect to the reference line.   
     
     
         8 . The wet duster module of the cleaner of  claim 1 , wherein the diffuser further includes a drain hole through which condensed condensate is discharged. 
     
     
         9 . The wet duster module of the cleaner of  claim 8 , wherein the diffuser includes a diffuser nozzle configured to discharge the heated moisture toward the duster, and
 a distance from the rotational axis of the rotational cleaning part to the diffuser nozzle is greater than a distance from the rotational axis of the rotational cleaning part to the drain hole.   
     
     
         10 . The wet duster module of the cleaner of  claim 1 , wherein the diffuser is disposed above the duster to discharge the heated moisture to an upper surface of the duster. 
     
     
         11 . The wet duster module of the cleaner of  claim 1 , wherein the module housing includes a suction port disposed at one side thereof to suction air, and
 the diffuser is disposed behind the suction port.   
     
     
         12 . The wet duster module of the cleaner of  claim 1 , wherein the module housing includes a diffuser installation groove which is formed to be recessed upward from a lower surface, and into which at least a portion of the diffuser is inserted. 
     
     
         13 . The wet duster module of the cleaner of  claim 1 , wherein a lower end of the diffuser is disposed to be spaced apart from an upper surface of the duster. 
     
     
         14 . The wet duster module of the cleaner of  claim 1 , wherein an inner end of the diffuser is disposed to be spaced apart from an outer end of the rotational cleaning part. 
     
     
         15 . The wet duster module of the cleaner of  claim 1 , wherein the module housing includes a partition wall configured to partition a duster driving motor configured to rotate the rotational cleaning part and the heat generator, and
 the diffuser is disposed closer to the heat generator than the duster driving motor with respect to the partition wall.   
     
     
         16 . A wet duster module of a cleaner, which mops and cleans a foreign substance on a floor, the wet duster module comprising:
 a module housing coupled to a cleaner main body, forming an appearance, and forming an internal space therein;   a partition wall extending from one side of the module housing to the internal space and partitioning the internal space into a first internal space and a second internal space surrounding the first internal space;   a water tank coupled to the module housing and storing water therein;   a duster disposed on a lower surface of the module housing;   a heat generator disposed in the first internal space and heating water supplied from the water tank; and   a diffuser disposed in the first internal space and connected to the heat generator to supply the heated moisture to the duster.   
     
     
         17 . The wet duster module of the cleaner of  claim 16 , wherein the duster rotates about a rotational axis, and
 the rotational axis is disposed in the second internal space.   
     
     
         18 . The wet duster module of the cleaner of  claim 16 , further comprising a duster driving motor disposed in the second internal space and rotating the duster. 
     
     
         19 . The wet duster module of the cleaner of  claim 16 , further comprising a water pump disposed in the second internal space and pumping the water stored in the water tank to the heat generator.
