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.

First claim

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.
