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 centre 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.
Abstract:
A surface cleaning apparatus comprises an air flow passage extending from a dirty air inlet to a clean air outlet. A suction motor is positioned in the air flow path. At least one cyclone is positioned in the air flow passage. An associated dirt collection chamber is exterior to the cyclone. The cyclone and the suction motor are positioned side by side and have generally parallel longitudinal axes. The dirt collection chamber may surround part of the suction motor. Alternately, or in addition, a pre-motor filter having an enhanced surface area may be provided by configuring the pre-motor filter to extend outwardly of the pre-motor filter, such as by overlie part of the cyclone or the dirt collection chamber.
Abstract:
A surface cleaning apparatus comprises a floor cleaning head having a dirty air inlet, a cleaning brush and a brush motor. An air flow passage extending from the dirty air inlet to a clean air outlet. An upper section is moveably mounted to the surface cleaning head between an storage position and an in use position. The upper section comprises a cleaning unit including a suction motor positioned in the air flow passage. At least one of the upper section and the cleaning unit is removably mounted to the floor cleaning head in a preset orientation. When the surface cleaning apparatus is assembled, the cleaning unit is spaced from the floor cleaning head. An alignment member is provided on the surface cleaning apparatus. The alignment member requires the one of the upper section and the cleaning unit to be in the preset orientation when mounted on the floor cleaning head. An electrical conductive member is electrically connected to the brush motor and releaseably electrically connected to the cleaning unit. The electrically conductive member is automatically connected to the cleaning unit when the one of the upper section and the cleaning unit is mounted to the floor cleaning head.
Abstract:
A process and reactor for chemical conversion is taught. The process allows the selective breaking of chemical bonds in a molecule by use of fast rise alternating current or fast rise pulsed direct current, each fast rise portion being selected to have a suitable voltage and frequency to break a selected chemical bond in a molecule. The reactor for carrying out such a process includes a chamber for containing the molecule and a generator for generating and applying the selected fast rise current.
Abstract:
A surface cleaning apparatus such as a hand vacuum cleaner comprises a first cyclone and at least one additional dirt separation unit. The at least one additional dirt separation unit is visible when the suction motor housing is removed from the hand vacuum cleaner.
Abstract:
A filter apparatus comprises first and second filters, each having an upstream surface and a downstream surface. At least one bypass channel extends from a position upstream of the upstream surface of the first filter to a position upstream of the upstream surface of the second filter.
Abstract:
A surface cleaning apparatus comprises a filtration apparatus comprising a cyclone downstream from the dirty air inlet and an openable filtration chamber comprising a screen downstream from the cyclone and upstream from the suction motor. The filtration chamber is accordingly a separate volume to that of the cyclone chamber and accordingly may be accessed to clean the screen independently of opening the cyclone chamber.
Abstract:
A surface cleaning apparatus comprises a dirt chamber. The dirt chamber comprises a first portion and a second portion. The first portion of the dirt chamber is transparent and the second portion has an increased opacity compared to the first portion to simulate a dirt fill line.
Abstract:
A vacuum cleaner has a front, an upper portion and a lower portion. The vacuum cleaner comprises an air flow passage extending from a nozzle having a dirty air inlet to a clean air outlet. A cyclone unit comprises at least one cyclone having a cyclone air inlet positioned in the air flow passage. A suction motor is positioned in the air flow passage. In one aspect, the vacuum cleaner is a hand vacuum cleaner and the nozzle is positioned at a lower portion of the hand vacuum cleaner and preferably below the vacuum cleaner. In another aspect, the vacuum cleaner is a hand vacuum cleaner and the nozzle includes a lower open sided passage. In accordance with another aspect, the vacuum cleaner has an air treatment member that is positioned at least partially above the air inlet.
Abstract:
A surface cleaning apparatus comprises a dirt inlet, a handle, a cyclonic cleaning unit comprising a plurality of cyclones and at least one dirt collection chamber, each of the plurality of cyclones having an outer wall, an interior, a fluid inlet downstream from the dirt inlet and a fluid outlet, the at least one dirt collection chamber having an outer wall and an interior, wherein the surface cleaning apparatus is constructed such that the interior of the at least one dirt collection chamber is visible from a position exterior to the surface cleaning apparatus and a fluid flow motor. The surface cleaning apparatus may have a filter with a housing that is at least partially transparent.
