Floor cleaning robot and cleaning apparatus

Abstract

A floor cleaning robot 1 includes a main body 10 , drive wheels 13 configured to movably support the main body 10 on a floor surface 31 , a first storage 11 that is provided in the main body 10 and that is configured to store a liquid 3 ; at least one nozzle 12 A that is disposed on a facing surface 10 A of the main body 10 facing the floor surface 31 and that is configured to eject the liquid 3 in a continuous flow 3 a and convert the continuous flow 3 a into droplets 3 b so that the liquid collides with the floor surface 31 in the form of droplets 3 b , and a collection section 14 that is disposed at a position different from the nozzles 12 A on the facing surface 10 A and configured to collect the liquid 3 ejected from the nozzles 12 A onto the floor surface 31.

What is claimed is: 
     
         1 . A floor cleaning robot comprising:
 a main body;   drive wheels configured to movably support the main body on a floor surface;   a first storage that is provided in the main body and that is configured to store a liquid;   at least one nozzle that is disposed on a facing surface of the main body facing the floor surface and that is configured to eject the liquid in a continuous flow and convert the continuous flow into droplets so that the liquid collides with the floor surface in a droplet shape; and   a collection section that is disposed on the facing surface at a position different from that of the nozzle and that is configured to collect the liquid ejected from the nozzle onto the floor surface.   
     
     
         2 . The floor cleaning robot according to  claim 1 , wherein
 the collection section is disposed to the rear of the nozzle in a movement direction of the main body by driving the drive wheels.   
     
     
         3 . The floor cleaning robot according to  claim 2 , wherein
 the nozzle is disposed forward from the drive wheels in the movement direction.   
     
     
         4 . The floor cleaning robot according to  claim 1 , wherein
 the collection section includes a suction section configured to suck the liquid that was ejected from the nozzle onto the floor surface into the interior of the main body.   
     
     
         5 . The floor cleaning robot according to  claim 4 , wherein
 the main body includes a first connection flow path configured to connect the suction section and the first storage.   
     
     
         6 . The floor cleaning robot according to  claim 4 , wherein
 the main body includes a second storage section configured to store the liquid sucked by the suction section.   
     
     
         7 . The floor cleaning robot according to  claim 6 , wherein
 the main body includes a second connection flow path configured to connect the second storage section and the first storage.   
     
     
         8 . The floor cleaning robot according to  claim 1 , wherein
 the main body includes a removal section configured to remove impurities contained in the liquid collected by the collection section.   
     
     
         9 . The floor cleaning robot according to  claim 1 , wherein
 the collection section includes an absorbent material configured to absorb the liquid ejected from the nozzle onto the floor surface.   
     
     
         10 . The floor cleaning robot according to  claim 1 , further comprising:
 a liquid feeding section configured to feed the liquid stored in the first storage to the nozzle.   
     
     
         11 . The floor cleaning robot of  claim 10 , wherein
 the liquid feeding section includes a pressurized gas storage section configured to seal a pressurized gas inside.   
     
     
         12 . The floor cleaning robot according to  claim 11 , further comprising:
 a stay section configured to be where the main body stays while cleaning is not being performed, wherein   the stay section includes a pressurized gas delivery section configured to deliver the gas to the pressurized gas storage section.   
     
     
         13 . The floor cleaning robot according to  claim 1 , further comprising:
 a detection section configured to detect the condition of the floor surface.   
     
     
         14 . The floor cleaning robot according to  claim 13 , further comprising:
 an ejection control section configured to control ejection of the liquid in accordance with the condition of the floor surface detected by the detection section.   
     
     
         15 . A cleaning apparatus comprising:
 a head section;   a first storage configured to store a liquid;   at least one nozzle that is disposed on a facing surface of the head section facing a floor surface and that ejects the liquid in a continuous flow and converts the continuous flow into droplets so that the liquid collides with the floor surface in a droplet shape; and   a collection section that is disposed on the facing surface at a position different from that of the nozzle and that is configured to collect the liquid ejected from the nozzle onto the floor surface.
