Vacuum cleaner with large debris receptacle
View Patent ↗A vacuum cleaning machine comprising a housing that includes a suction nozzle that is adapted to move along a surface to be cleaned and a receptacle coupled to the housing for holding particles removed from the surface during operation of the vacuum cleaning machine. The receptacle is provided with an external opening for the introduction of debris particles therein which are not ordinarily removable from the surface through the suction-generating apparatus. The vacuum cleaning machine can be an upright vacuum cleaning machine and the receptacle can be mounted to the handle. The receptacle can also be incorporated into a dirt cup in a cyclone separator module.
1. A vacuum cleaning machine comprising:
a housing that includes a suction nozzle that is adapted to move along a surface to be cleaned;
an air/dirt separator to remove dirt from air;
a working air conduit between the suction nozzle and the air/dirt separator;
a dirt receptacle in communication with the air/dirt separator for receiving debris removed from air in the air/dirt separator, the dirt receptacle having an external opening; and
a suction source fluidly connected to the suction nozzle, the working air conduit, the air/dirt separator and the dirt receptacle for moving dirt-laden air from the suction nozzle through the working air conduit and through the dirt separator;
wherein the external opening can enable the introduction of debris particles which, due to size or configuration, cannot be removed by the vacuum cleaning machine from the surface to be cleaned.
2. A vacuum cleaning machine according to claim 1 wherein the external opening is selectively sealed by a closure element.
3. A vacuum cleaning machine according to claim 2 wherein the closure element is a door which is mounted for movement between a sealed position overlying the external opening and an open position providing external access through the external opening.
4. A vacuum cleaning machine according to claim 3 wherein the door is pivotally mounted for rotational movement between the open and sealed positions.
5. A vacuum cleaning machine according to claim 1 wherein the housing includes a base that is adapted to move across the surface to be cleaned and an upright portion that is pivotally mounted to the base and the dirt receptacle is mounted to the upright portion.
6. A vacuum cleaning machine according to claim 5 wherein the air/dirt separator comprises a cyclone separator and the dirt receptacle is mounted beneath the cyclone separator.
7. A vacuum cleaning machine according to claim 1 wherein the air/dirt separator comprises a cyclone separator and the dirt receptacle is mounted beneath the cyclone separator.
8. A vacuum cleaning machine according to claim 1 wherein the air/dirt separator comprises a cyclone separator and wherein the external opening is positioned in the cyclone separator.
