Benefits of technology

[0012]A stop may be provided so that, when the catch is in the unreleasable position, the stop prevents release of the catch if the appliance is subjected to a sudden vertical movement. This feature prevents the catch from returning to a releasable position even if the appliance

Problems solved by technology

Previous proposals for catches inhibited from release when the appliance is lifted had a drawback in that slight relative movement between the component and the chassis when the appliance was resting on a surface tended to put the catch into the unreleasable position.
For example, it was f

Embodiment Construction

[0024]Referring to FIG. 1, an upright vacuum cleaner indicated generally by the reference numeral 1 comprises a main chassis 2 which supports dirt and dust separation apparatus 3 incorporating a collecting chamber 4. The lower part of the vacuum cleaner 1 comprises a cleaner head 5 for engaging with the floor surface. The cleaner head 5 has a downwardly facing suction inlet and a brush bar (not shown), mounted in the mouth of the inlet, for agitating the floor surface. The cleaner head 5 is pivotably mounted to a motor housing 6, which houses the motor and fan of the cleaner 1. Support wheels 7 are mounted to either side of the motor housing 6 for supporting the cleaner 1 and allowing movement across a floor surface.

[0025]A spine 8 of the chassis 2 extends upwardly from the motor housing 6 to provide support for the components of the cleaner 1. A cleaning wand 9 having a second dirty air inlet 10 is connected by way of a hose (not shown) to the chassis 2 at the base of the spine 8. ...

Abstract

A domestic appliance, such as a cyclonic vacuum cleaner, includes a component such as a separating apparatus, carried by a chassis. A catch is operable to release the component from the chassis. The component and the chassis can move with respect to each other. When the appliance is lifted there is relative movement, against the force of a resilient member, between the component and the chassis, so that the catch occupies a position that inhibits its release. Previous catches that inhibited from release when the appliance is lifted had a drawback in that slight relative movement between the component and the chassis when the appliance was resting on a surface tended to put the catch into the unreleasable position. The resilient member provides resistance to the catch moving into the locked position, thereby ensuring that the catch is inhibited from release only when the appliance is lifted from a surface.

Description

REFERENCE TO RELATED APPLICATIONS[0001]This application is a national stage application under 35 USC 371 of International Application No. PCT / GB2007 / 002674, filed Jul. 16, 2007, which claims the priority of United Kingdom Application No. 0615681.4, filed Aug. 8, 2006, the contents of which prior applications are incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention relates to a domestic appliance, such as a vacuum cleaner.BACKGROUND OF THE INVENTION[0003]Vacuum cleaners which separate dirt and dust from an airflow without the use of a filter bag, so-called bagless vacuum cleaners, are becoming increasingly popular. Most bagless cleaners use cyclonic or centrifugal separation to spin dirt and dust from the airflow. By avoiding the use of a filter bag as the primary form of separation, it has been found possible to maintain a consistently high level of suction, even as the collecting chamber fills with dirt and dust.[0004]In a typical cyclonic vacuum cleaner, an a...
