Self-propelling cleaner

Abstract

A self-propelling cleaner 1 performs dust removal processing in which a comb is brought close to a rotary brush with prescribed timing and dust is removed from the rotary brush. In the dust removal processing, the comb is slid in such a direction as to come closer to the brush, even dust that is stuck to the base portions of bristles of the rotary brush can be removed. A self-propelling cleaner is provided that is free of an event that it performs cleaning in a state that a large amount of dust is stuck to the rotary brush.

1 . A self-propelling cleaner comprising: 
 a main body;    a self-propelling section that propels the main body autonomously;    a sucking section provided with a suction mouth and a suction fan, and collects dust into the main body through the suction mouth by rotating the suction fan;    a rotating section that rotates a rotary brush that is rotatably attached to the suction mouth;    a comb provided adjacent to the rotary brush to be slidable in a direction as to be brought into contact with and separated from the rotary brush;    a cleaning section that controls the self-propelling section and the sucking section to perform cleaning while propelling the main body within a preset cleaning area; and    a dust removing section that removes dust attached to the comb by causing the sucking section to rotate the suction fan and causing the rotating section to rotate the rotary brush while sliding the comb to be in contact with the rotary brush, after completion of the cleaning by the cleaning section.    
   
   
       2 . A self-propelling cleaner comprising: 
 a main body;    a self-propelling section that propels the main body autonomously;    a sucking section provided with a suction mouth and a suction fan, and collects dust into the main body through the suction mouth by rotating the suction fan;    a rotating section that rotates a rotary brush that is rotatably attached to the suction mouth;    a comb provided adjacent to the rotary brush to be slidable in a direction as to be brought into contact with and separated from the rotary brush;    a cleaning section that controls the self-propelling section and the sucking section to perform cleaning while propelling the main body within a preset cleaning area; and    a dust removing section that removes dust attached to the comb, at a prescribed timing, by causing the sucking section to rotate the suction fan and causing the rotating section to rotate the rotary brush while sliding the comb to be in contact with the rotary brush.    
   
   
       3 . The self-propelling cleaner according to  claim 2 , wherein the dust removing section removes dust attached to the comb after completion of the cleaning by the cleaning section.  
   
   
       4 . A self-propelling cleaner comprising: 
 a main body;    a self-propelling section that propels the main body autonomously;    a sucking section provided with a suction mouth and a suction fan, and collects dust into the main body through the suction mouth by rotating the suction fan;    a rotating section that rotates a rotary brush that is rotatably attached to the suction mouth;    a comb having teeth thereof on both sides that are opposed to each other with respect to the rotary brush interposed therebetween, and provided adjacent to the rotary brush to be slidable in a direction perpendicular to a rotation axis of the rotary brush as to be brought into contact with and separated from the rotary brush;    a cleaning section that controls the self-propelling section and the sucking section to perform cleaning while propelling the main body within a preset cleaning area in a state where the teeth of the comb provided at rear to a direction of the propelling of the main body are in contact with the rotary brush; and    a dust removing section that removes dust attached to the comb, at a prescribed timing, by causing the sucking section to rotate the suction fan and causing the rotating section to rotate the rotary brush in a reverse direction while sliding the comb to be in a state where the teeth of the comb provided at front to the direction of the propelling of the main body are in contact with the rotary brush.    
   
   
       5 . The self-propelling cleaner according to  claim 4 , wherein the dust removing section removes dust attached to the comb after completion of the cleaning by the cleaning section.
