US 2019/0335967 A1 · FILTERING DEVICES FOR EVACUATION STATIONS

Abstract

A bag-based filtering device for collecting debris from a cleaning robot via a debris evacuation station includes a filter bag configured to separate at least the portion of the evacuated debris from a flow of air generated by the evacuation station. The filtering device includes a conduit extending inward from an opening of the filter bag into the receptacle. The conduit is configured to pneumatically connect a receptacle of the filtering device with an inlet of the filtering device to direct the flow of air generated by the evacuation station through the filter bag to separate at least the portion of the evacuated debris from the flow of air.

Dependent claims

A bag-based filtering device for collecting debris from a cleaning robot via a debris evacuation station, the filtering device comprising:

a filter bag at least partially forming a receptacle for receiving at least a portion of the evacuated debris, the filter bag configured to separate at least the portion of the evacuated debris from a flow of air generated by the evacuation station;
an inlet configured to interface with an outlet of the evacuation station;
and
a conduit extending inward from an opening of the filter bag into the receptacle, the conduit comprising an opening proximate the inlet, the opening of the conduit having a width greater than a width of an opening of the inlet,
wherein the conduit is configured to pneumatically connect the receptacle with the inlet of the filtering device to direct the flow of air generated by the evacuation station through the filter bag to separate at least the portion of the evacuated debris from the flow of air.

2 more elements

An evacuation station for reducing obstructions in a filtering device inlet, the evacuation station comprising:

one or more conduits comprising an intake configured to interface with a cleaning robot;
a filtering device comprising
a filter bag at least partially forming a receptacle,
an inlet configured to interface with an outlet of the one or more conduits, and
a conduit configured to pneumatically connect the inlet to the receptacle, the conduit extending inward from an opening of the filter bag into the receptacle;
and
an air mover configured to produce a flow of air containing debris from a debris bin of the cleaning robot, the flow of air travelling through the one or more conduits, through the conduit of the filtering device, and through the filter bag such that at least a portion of the debris is separated from the flow of air and received by the receptacle.
