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 chamber positioned in the air flow passage and having a cyclone end wall at a first end, a cyclone chamber sidewall extending from the cyclone end wall to a dirt outlet end spaced from the first end, a cyclone air inlet, a cyclone air outlet, and a dirt outlet extending along a portion of the perimeter of the cyclone chamber sidewall at the dirt outlet end of the cyclone chamber;
(c) a dirt collection chamber exterior to the cyclone chamber and in communication with the dirt outlet;
(d) a plate positioned at the dirt outlet end of the cyclone chamber, wherein a first portion of the plate abuts the cyclone chamber sidewall and a second portion of the plate overlies and is spaced apart from the cyclone chamber sidewall to define the dirt outlet whereby dirt exiting the cyclone chamber via the dirt outlet travels in a generally outwardly direction, wherein at least one of the plate and the cyclone end wall is openable; and
,(e) a suction motor positioned in the air flow passage.

Abstract
A cyclone for a surface cleaning apparatus has spaced apart and opposed first and second cyclone chamber end walls and a cyclone chamber sidewall extending therebetween. At least one of the first cyclone chamber end wall and the second cyclone chamber end wall is openable so as to provide access to the cyclone chamber. An opening extends along only a portion of the perimeter of the cyclone chamber sidewall and is positioned adjacent the second cyclone chamber end wall, the opening defining the dirt outlet whereby dirt exiting the cyclone chamber via the dirt outlet travels in a generally outwardly direction to an exterior dirt collection chamber.
