Exhaust air feedback robot cleaner equipped with a disinfectant anion generator

Abstract

Disclosed is an exhaust air feedback robot cleaner equipped with a disinfectant anion generator, including a suction motor to intake not only air but also dust from a to-be-cleaned surface through a suction unit installed at the bottom surface and a dust collector to trap dust so as to allow dust-free air to be discharged via the suction motor. In the robot cleaner, the disinfectant anion generator emits disinfectant anions to disinfect the air having been discharged via the suction motor, a spray nozzle installed at the front end of an intake port of the robot cleaner sprays the disinfected air toward the cleaning surface through an exhaust air feedback unit so that the dust on the to-be-cleaned surface may be scattered and disinfected, and finally the air, together with the dust, is sucked in by the suction motor and circulated again to the exhaust air feedback unit.

1 . An exhaust air feedback robot cleaner configured such that foreign matter on a to-be-cleaned surface are sucked along with air through a suction unit installed on a bottom surface by a suction motor, the sucked foreign matter is collected by a dust collector, and air free from the foreign matter is discharged through a drive motor,
 wherein the air discharged through the suction motor is disinfected by disinfectant anions discharged from a disinfectant anion generator, is then sprayed through an exhaust air circulating unit toward the to-be-cleaned surface by a spray nozzle installed at a front end of a suction port of the robot cleaner to cause the foreign matter on the to-be-cleaned surface to escape and be disinfected, and is finally sucked along with the foreign matter by the suction motor so as to be circulated into the exhaust air circulating unit.   
     
     
         2 . The exhaust air feedback robot cleaner according to  claim 1 , wherein the anions sprayed onto the to-be-cleaned surface through the spray nozzle are sucked through the suction unit, and are then re-sprayed onto the to-be-cleaned surface along with the anions discharged from the disinfectant anion generator, so that a disinfection capacity is increased.
