Embodiment Construction

[0054] Referring to the drawings, there is shown an embodiment of an apparatus 10 embodying various aspects of the present invention. Apparatus 10 includes an upright member 12 including a user-graspable handle 13 and a floor implement 14 . Apparatus 10 includes a suction source (not shown) in fluid communication with surface tool 14 to provide suction thereto. The floor tool 14 is supported on wheels 15 provided at the rear thereof, and the user grabs the handle 13 of the upright member 12 and pushes and pulls the floor tool 14 on the ground S to clean the ground as required. The floor tool 14 includes a housing 16 having an inner surface 18 defining a cavity 20 for receiving a cleaning element 22 . Housing 16 also includes a chamber inlet 24 that receives dirty air and a chamber outlet 26 that communicates with a suction source.

[0055]Upright member 12 is pivotally connected to ground tool 14 remote from the front edge of ground tool 14 . Upright member 12 includes the ...

Abstract

The present invention discloses a floor tool for use in a floor cleaning device, the device including a suction source, the floor tool comprising: a housing having an inner surface defining a cavity for receiving at least a portion of a cleaning element. a cavity, said housing comprising: a cavity inlet for receiving dirty air; and a cavity outlet in communication with said suction source, wherein said housing is composed of at least two housing parts providing said inner surface Formed, all of said housing parts are permanently connected or permanently joined to each other.

Description

technical field [0001] The invention relates to a floor tool for a floor cleaning device and / or a device comprising said floor tool. In particular, the present invention relates to a device that utilizes a suction source to draw dirt and / or debris from the floor being cleaned, where the dirt and / or debris is stored in a dust chamber or bag to be emptied by the user. Such devices are commonly referred to as "vacuum cleaners". Background technique [0002] The performance of a vacuum cleaner is determined by several parameters, including how efficiently the cleaner can extract dirt / debris for a given suction power, i.e. energy efficiency, and how noisy it is during use. To maximize these efficiencies, it is beneficial to reduce suction losses and reduce turbulence in the intake air flow path. [0003] Known vacuum cleaners include a floor tool having a cavity with a cavity inlet through which airborne dirt / debris enters the tool and flows to a dust collection cavity. The ca...
