Cleaning apparatus

Abstract

A cleaning apparatus according to one or more embodiment may include a moving body configured to move on a surface in a moving direction; and a cleaning unit provided in the moving body and is configured to clean the surface to be cleaned. The cleaning unit may include: an intake nozzle; an intake unit configured to suction in objects, along with air, from the surface to be cleaned through the intake nozzle; a collection container configured to separate the objects that are suctioned in and collect the objects in an inside of the collection container; an air discharge duct configured to guide air suctioned in by the intake unit from an air outlet of the intake unit to an inside of the cleaning unit; and a cover member that covers at least the air discharge duct, and is configured to form an internal space with the air discharge duct.

1 . A cleaning apparatus comprising:
 a moving body configured to move on a surface to be cleaned in a moving direction; and   a cleaning unit that is provided in the moving body and is configured to clean the surface to be cleaned,   wherein the cleaning unit comprises:   an intake nozzle;   an intake unit configured to suction in objects, along with air, from the surface to be cleaned through the intake nozzle;   a collection container configured to separate the objects that are suctioned in and collect the objects in an inside of the collection container;   an air discharge duct configured to guide air suctioned in by the intake unit from an air outlet of the intake unit to an inside of the cleaning unit; and   a cover member that covers at least the air discharge duct, and is configured to form an internal space with the air discharge duct.   
     
     
         2 . The cleaning apparatus according to  claim 1 ,
 wherein the cleaning unit is attached to a back face of the moving body,   the intake unit suctions in air inside the collection container through an outlet provided in an upper portion of a front face of the collection container on a side of the moving direction, and   the air discharge duct forms a discharging air flow channel extending from the air outlet of the intake unit to an internal space sideward of the collection container.   
     
     
         3 . The cleaning apparatus according to  claim 1 ,
 wherein the cleaning unit further comprises a distribution duct that is attached to an outlet of the air discharge duct and is configured to distribute a discharging air flow from the outlet into a plurality of air flows toward the internal space.   
     
     
         4 . The cleaning apparatus according to  claim 3 ,
 wherein the distribution duct has a tubular shape whose inside is hollow, and comprises a plurality of opening portions in an outer circumferential surface of the distribution duct.   
     
     
         5 . The cleaning apparatus according to  claim 4 ,
 wherein the plurality of opening portions are formed in portions, of the outer circumferential surface, that oppose an inner face of the cover member.   
     
     
         6 . The cleaning apparatus according to  claim 1 ,
 wherein the collection container is arranged at the center, in a width direction, of a back face of the moving body,   the intake unit comprises a first air outlet provided in a side face of a casing of the intake unit on one side in the width direction, and a second air outlet provided in a side face on the other side, and   the air discharge duct comprises:   a first air discharge duct that forms a first discharging air flow channel extending from the first air outlet to a space formed between the cover member and an upper portion of a first side face of the collection container on the one side, and   a second air discharge duct that forms a second discharging air flow channel extending from the second air outlet to a space formed between the cover member and an upper portion of a second side face of the collection container on the other side.   
     
     
         7 . The cleaning apparatus according to  claim 1 , further comprising:
 a driving force transmission unit configured to move the moving body by transmitting a driving force in the moving direction to the surface to be cleaned.
