Abstract
A vacuum cleaner having an elongated support body, a nozzle attached to a lower end of the elongated support body by an articulated joint, a motor, a fan unit, a debris container, and an air passage that extends from the nozzle device, past the articulated joint by a flexible hose and to an air passage in the support body. The flexible hose is formed with a generally rectangular cross section.
Claims21
A cyclone separator for a vacuum cleaner, the cyclone separator comprising:
- a debris container having an open end, a closed end, a sidewall extending from the open end to the closed end, and a cyclone inlet through the sidewall;
- a filter insert having an end wall adapted to abut the open end of the debris container on a first side of the cyclone inlet, a cyclone outlet through the end wall, and a filtering portion extending inside the debris container from the end wall to a point past the cyclone inlet, the filtering portion comprising one or more filters through which air can pass to travel from the cyclone inlet to the cyclone outlet;
- a partition wall extending from the filter insert towards the sidewall on a second side of the cyclone inlet, the second side being opposite the first side such that the cyclone inlet is located between the end wall and the partition wall;
- a first directing portion extending from the partition wall towards the closed end of the debris container;
- and
- a second directing portion extending from the end wall towards the closed end of the debris container;
- wherein the first directing portion and the second directing portion direct airflow in the dirt container in a helical direction around the filter insert.

A vacuum cleaner comprising:
- a base having a dirty air inlet formed therein;
- a directing handle connected to the dirty air inlet;
- an air path extending from the dirty air inlet to a fan and associated motor, the fan and associated motor being adapted to selectively generate a working air flow into the dirty air inlet and through the air path;
- a debris container selectively positioned in the air path, the debris container having an open end, a closed end, a sidewall extending from the open end to the closed end, and a cyclone inlet through the sidewall;
- a filter insert having an end wall adapted to abut the open end of the debris container on a first side of the cyclone inlet, a cyclone outlet through the end wall, and a filtering portion extending inside the debris container from the end wall to a point past the cyclone inlet, the filtering portion comprising one or more filters through which air can pass to travel from the cyclone inlet to the cyclone outlet;
- a partition wall extending from the filtering portion towards the sidewall on a second side of the cyclone inlet, the second side being opposite the first side such that the cyclone inlet is located between the end wall and the partition wall;
- a first directing portion extending from the partition wall towards the closed end of the debris container;
- and
- a second directing portion extending from the end wall towards the closed end of the debris container;
- wherein the first directing portion and the second directing portion direct airflow in the dirt container in a helical direction around the filter insert.
