Embodiment Construction

[0021] see first figure 1 , which only shows the outline of the main body 10 of a cylindrical vacuum cleaner. A suction hose, generally indicated by numeral 11, extends from one end (referred to herein as the front end of the main body 10) for connection to a cleaning tool (or the free end of the suction hose may be used for vacuuming without a cleaning tool ). For certain sweeping tasks, such as sweeping floors, the cleaning tool is usually connected to the hose via a centrally rigid rod that can be telescopically extended in the form of a sleeve. These parts are all conventional parts. At the end (rear end) of the body 10 opposite to where the hose 11 extends, said body has wheels shown schematically at 12, a corresponding wheel on the side of the body 10 opposite to the wheels 12 is not shown in the figure show. Usually, another unshown wheel, such as a caster, can be provided under the main body 10 towards the front, so that the cleaner can be easily moved on the floor...

Abstract

According to one aspect of the present invention, we provide a suction cleaner comprising a suction unit having a source of suction and a separator / collector arrangement for separating entrained dirt from a flow of air created by the source of suction and for collecting and retaining such separated dirt for disposal; and a flexible suction hose for conveying suction airflow to the suction unit from a hose inlet at which a cleaning tool may be connected; wherein the suction hose comprises a first portion which can be accommodated in the suction unit and deployed therefrom when required, and a second portion having the inlet and connected to the first hose portion.

Description

technical field [0001] The invention relates to a vacuum cleaner (vacuum cleaner), which has a suction hose for connecting a suction device to a suction wand and / or a suction tool. Background technique [0002] The present invention relates to a vacuum cleaner of the so-called "drum" type. This vacuum cleaner comprises a suction device having a suction source (a motor and impeller) and a separation / collection device for separating dust from the airflow generated by the suction source and collecting and storing the separated dust for Take appropriate action. The separation / collection means may comprise one or more filters for removing entrained dust from the gas flow and / or one or more cyclones for separating by centrifugal force. In use, the dust suction device is placed near the place where the dust suction operation is to be performed, and a flexible suction hose connects the suction device to a dust suction tool held by the dust suction operator. When cleaning floors o...
