Abstract

A self-propelled cleaning robot that can continuously perform cleaning even on a large space can be provided without increasing in size. The self-propelled cleaning robot that self-travels on and cleans a target flat surface (SF) of a structure (SP) installed outside, the self-propelled cleaning robot includes: a robot body (2) in which a self-propelled moving means is provided and a cleaning unit (10) that is provided in a side surface of the robot body (2). The cleaning unit (10) includes a rotatable brush (12) that includes a shaft unit (12a) and a brush unit (12b) provided on the shaft unit (12a) and an airflow forming cover (15) that is provided so as to cover a portion located on a side of the robot body (2) and on an opposite side to the flat surface in the brush (12) during cleaning of the flat surface. The robot body (2) is not enlarged because the provision of a dust collecting portion in the robot body (2) is not required. Because dust suction is not required, power consumption necessary can be reduced, and an extremely large space can continuously be cleaned.

Claims

1. A self-propelled cleaning robot that self-travels on and cleans a flat surface of a structure installed outside, the self-propelled cleaning robot comprising:

a robot body in which a self-propelled moving means is provided; and

a cleaning unit that is provided in a side surface of the robot body,

wherein the cleaning unit includes;

a rotatable brush that includes a shaft unit and a brush unit provided on the shaft unit; and

an airflow forming cover that is provided so as to cover a portion located on a side of the robot body and on an opposite side to the flat surface in the brush during cleaning of the flat surface.

2. The self-propelled cleaning robot according to claim 1, wherein the brush is controlled so as to rotate in a direction in which a leading end portion of the brush comes close to the flat surface while separating from the robot body during cleaning of the flat surface.

3. The self-propelled cleaning robot according to claim 1, wherein the cleaning unit includes an air supply unit that blows air toward the brush, and

an air blow-off port of the air supply unit is provided in an inner surface of the airflow forming cover.

6. The self-propelled cleaning robot according to claim 1, wherein the shaft unit of the brush is constructed with a hollow pipe,

a blow-off port that blows the air is provided in a side surface of the shaft unit, and

the cleaning unit includes the air supply unit that supplies the air to the shaft unit of the brush.

4. A self-propelled cleaning robot that self-travels on and cleans a flat surface of a structure installed outside, the self-propelled cleaning robot comprising:

a robot body in which a self-propelled moving means is provided; and

a cleaning unit that is provided in a side surface of the robot body,

wherein the cleaning unit includes;

a rotatable brush that includes a shaft unit and a brush unit provided on the shaft unit; and

an air supply unit that blows air toward the brush and toward a direction separating from the robot body, and

the brush is controlled so as to rotate in a direction in which a leading end portion of the brush comes close to the flat surface while separating from the robot body during cleaning of the flat surface.

5. The self-propelled cleaning robot according to claim 4, wherein the cleaning unit includes an airflow forming cover that is provided so as to cover a portion located on a side of the robot body and on an opposite side to the flat surface in the brush during cleaning of the flat surface, and

an air blow-off port of the air supply unit is provided in an inner surface of the airflow forming cover.

7. The self-propelled cleaning robot according to claim 4, wherein the shaft unit of the brush is constructed with a hollow pipe,

a blow-off port that blows the air is provided in a side surface of the shaft unit, and

the cleaning unit includes the air supply unit that supplies the air to the shaft unit of the brush.
