Mop module of cleaning device

Abstract

There is disclosed a mop module of a vacuum cleaner including a module housing; a water tank disposed above the module housing and configured to store water therein; at least one rotary cleaning part disposed under the module housing, the rotary cleaning part to which a mop is coupled; a heat generator configured to heat water supplied from the water tank; and a diffuser provided under the heat generator and configured to supply moisture heated in the heat generator to the mop, and the diffuser may include a diffuser housing coupled to the module housing; and a moisture supply hole formed in the diffuser housing, the moisture supply hole through which the moisture heated in the heat generator is discharged, and the moisture supply hole may be provided along a circumferential direction in plural, and the plurality of moisture supply holes have different diameter, respectively, thereby causing an effect of making the flow amount of the discharged moisture uniform.

1 . A mop module of a vacuum cleaner configured to perform cleaning by wiping out foreign substances from the floor surface, the mop module comprising:
 a module housing;   a water tank disposed above the module housing and configured to store water therein;   at least one rotary cleaning part disposed under the module housing, the rotary cleaning part to which a mop is coupled;   a heat generator configured to heat water supplied from the water tank; and   a diffuser provided under the heat generator and configured to supply moisture heated in the heat generator to the mop,   wherein the diffuser comprises,   a diffuser housing coupled to the module housing; and   a moisture supply hole formed in the diffuser housing, the moisture supply hole through which the moisture heated in the heat generator is discharged, and   the moisture supply hole is provided along a circumferential direction in plural, and the plurality of moisture supply holes have different diameters, respectively.   
     
     
         2 . The mop module of the vacuum cleaner of  claim 1 , wherein the diffuser is connected to the heat generator, and
 the plurality of moisture supply holes have diameters that gradually increase as getting farther away from a point connected to the heat generator.   
     
     
         3 . The mop module of the vacuum cleaner of  claim 1 , wherein the diffuser further comprises,
 a guide rib protruding formed downward from the diffuser housing and formed along a circumferential direction.   
     
     
         4 . The mop module of the vacuum cleaner of  claim 1 , wherein the diffuser further comprises,
 a drain discharge portion downward from the diffuser housing.   
     
     
         5 . The mop module of the vacuum cleaner of  claim 1 , wherein the diffuser is connected to the heat generator, and has an inner space where moisture flows, which becomes narrower as getting farther away from a point connected to the heat generator. 
     
     
         6 . The mop module of the vacuum cleaner of  claim 1 , wherein the diffuser further comprises,
 a diffuser cover coupled to the diffuser housing and forming a space in which moisture flows.   
     
     
         7 . The mop module of the vacuum cleaner of  claim 6 , wherein the diffuser cover comprises,
 a cover body covering the diffuser housing; and   a flow rate adjustment part protruding toward the differ housing from the cover body.   
     
     
         8 . The mop module of the vacuum cleaner of  claim 7 , wherein the diffuser is connected to the heat generator, and the flow rate adjustment part has a protruding height that varies based on the distance from a point connected to the heat generator. 
     
     
         9 . The mop module of the vacuum cleaner of  claim 7 , wherein the diffuser is connected to the heat generator, and
 the flow rate adjustment part has a protruding height that increases as getting farther away from a point connected to the heat generator.   
     
     
         10 . The mop module of the vacuum cleaner of  claim 1 , wherein the moisture supply hole is formed along a circumferential direction in a shape of a long hole. 
     
     
         11 . The mop module of the vacuum cleaner of  claim 10 , wherein the diffuser is connected to the heat generator, and
 the moisture supply hole is formed along a circumferential direction, with a radial diameter that increases gradually.   
     
     
         12 . The mop module of the vacuum cleaner of  claim 10 , wherein the diffuser further comprises,
 a guide pole protruding toward the heat generator from the diffuser housing and configured to eliminate a water film generated in the heat generator.   
     
     
         13 . The mop module of the vacuum cleaner of  claim 10 , wherein the diffuser further comprises,
 a guide inclined surface configured to guide moisture introduced from the heat generator to the moisture supply hole.
