Electric cleaning apparatus

Abstract

An electric cleaning apparatus, which comprises an autonomous cleaning unit which moves autonomously over a surface to be cleaned and collects dust, and a station unit which has a charging electrode for the autonomous cleaning unit, wherein the autonomous cleaning unit includes a first body case having a first inlet, a secondary battery which accumulates electric power supplied from the charging electrode, a first dust collecting container which accumulates dust sucked from the first inlet, and an electric blower which is driven by electric power supplied from the secondary battery and makes negative pressure act on the first dust collecting container, and wherein the station unit is provided with a second body case having a second inlet which sucks other dust different from the dust which the autonomous cleaning unit collects.

1 : An electric cleaning apparatus, comprising:
 an autonomous cleaning unit which moves autonomously over a surface to be cleaned and collects dust; and   a station unit which has a charging electrode for the autonomous cleaning unit, wherein   the autonomous cleaning unit includes   a first body case having a first inlet,   a secondary battery which accumulates electric power supplied from the charging electrode,   a first dust collecting container which accumulates dust sucked from the first inlet, and   an electric blower which is driven by electric power supplied from the secondary battery and makes negative pressure act on the first dust collecting container, and wherein   the station unit is provided with a second body case having a second inlet which sucks other dust different from the dust which the autonomous cleaning unit collects.   
     
     
         2 : The electric cleaning apparatus according to  claim 1 , wherein the station unit includes a suction air passage which connects the second inlet with the first inlet or the first dust collecting container when the autonomous cleaning unit homes to the station unit. 
     
     
         3 : The electric cleaning apparatus according to  claim 1 , wherein the station unit includes
 a second dust collecting container which accumulates dust sucked from the second inlet, and   a second electric blower which makes negative pressure act on the second dust collecting container.   
     
     
         4 : The electric cleaning apparatus according to  claim 3 , wherein the station unit includes a transit air passage which connects the first dust collecting container and the second dust collecting container when the autonomous cleaning unit homes to the station unit. 
     
     
         5 : The electric cleaning apparatus according to  claim 1 , wherein the station unit includes
 a dust transport duct which is coupled with the autonomous cleaning unit and is fluidically connected to the first dust collecting container,   a second dust collecting container which accumulates dust transported for disposal from the first dust collecting container through the dust transport duct, and   a second electric blower which makes negative pressure act on the dust transport duct via the second dust collecting container,   wherein the second dust collecting container is provided with a multistage centrifugal separating unit including a first centrifugal separating portion which centrifugally separates dust flowing from the dust transport duct from air, and a second centrifugal separating portion which separates dust passing the first centrifugal separating portion from air.
