Cyclone construction for a surface cleaning apparatus
First Claim
1. A surface cleaning apparatus comprising:
- (a) an air flow passage extending from a dirty air inlet to a clean air outlet;
(b) a cyclone positioned in the air flow passage and having a cyclone air inlet and a cyclone air outlet at one end of a cyclone chamber, a dirt outlet spaced from the cyclone air inlet, a cyclone chamber wall and a centrally positioned longitudinal axis;
(c) a dirt collection chamber in communication with the dirt outlet and having an openable wall moveably mounted to the surface cleaning apparatus and a centrally positioned longitudinal axis, the openable wall having a centre and a mounting side;
(d) a plate moveably mounted between a closed position in which the plate is positioned at an interface of the dirt collection chamber and the cyclone and an open position in which the plate is moved away from the interface, the plate is moveably connected to the openable wall so that as the openable wall moves from a closed position to an open position, the plate is moved to the open position regardless of the orientation of the cyclone and the orientation of the plate moves to a different orientation with respect to the openable wall;
(e) a biasing member biasing the plate towards the mounting side of the openable wall; and
,(f) a suction motor positioned in the air flow passage.

Abstract
The surface cleaning apparatus includes a cyclone positioned in am air flow passage. The cyclone has a cyclone air inlet and a cyclone air outlet, a dirt outlet spaced from the cyclone air inlet, a cyclone chamber wall and a longitudinal axis. The surface cleaning apparatus also includes a dirt collection chamber in communication with the dirt outlet. The dirt collection chamber has an openable wall mounted to the surface cleaning apparatus by a hinge and a centrally positioned longitudinal axis, the openable wall has a center and a hinge side. The surface cleaning apparatus also includes a plate positioned at an interface of the dirt collection chamber and the cyclone. The plate is moveably mounted to the openable wall. The surface cleaning apparatus also includes a biasing member biasing the plate towards the hinge side of the openable wall a suction motor positioned in the air flow passage.

11. A surface cleaning apparatus comprising:
-
(a) an air flow passage extending from a dirty air inlet to a clean air outlet; (b) a cyclone positioned in the air flow passage and having a cyclone air inlet at an inlet end of the cyclone, a cyclone air outlet, a dirt outlet spaced from the cyclone air inlet at a dirt outlet end of the cyclone and a cyclone chamber wall; (c) a dirt collection chamber in communication with the dirt outlet and having an openable wall moveable between an open position and a closed position; (d) a plate positioned at the dirt outlet end of the cyclone and moveable between an open position in which the plate is in a first orientation with respect to the openable wall and a closed position in which the plate is in a second orientation, different from the first orientation, with respect to the openable wall, the plate is attached to the openable wall whereby, as the openable wall moves from its closed position to the its open position, the openable wall pulls the plate from its closed position to its open position and the orientation of the plate with respect to the openable wall is adjusted; and
,(e) a suction motor positioned in the air flow passage. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 25, 26, 27)
