Document Type and Number:
Japanese Patent JP6522905
Kind Code:
B2
Abstract:
An electric vacuum cleaning apparatus (1) is provided with an autonomous robotic vacuum cleaner (2) that autonomously moves between surfaces to be cleaned and collects dust and a station (5) that is capable of fluidly connecting to the autonomous robotic vacuum cleaner (2). The autonomous robotic vacuum cleaner (2) is provided with: a container body (38) for accumulating dust collected by the autonomous robotic vacuum cleaner (2), the container body (38) including a bottom wall (132) that has a disposal port (41) provided thereto; and a disposal lid (42) for opening and closing the disposal port (41). The station unit (5) is provided with: a dust transfer pipe (25) that is connected to the disposal port (41); a secondary dust container (68) for accumulating dust that is disposed of from the container body (38) through the dust transfer pipe (25); and a secondary electric blower (69) that generates negative suction pressure in the dust transfer pipe (25) via the secondary dust container (68). At least one irregularly shaped ventilation groove (133) that causes air to flow below the dust (D) within the container body (38) as a result of the negative pressure generated by the secondary electric blower (69) is provided to the inner surface (132a) of the bottom wall (132) of the container body (38).
