International Classification:

A47L 7/00

US Classification:

15320

Abstract:

An embodiment of the cleaning and floor care system has a reservoir assembly and a wet/dry vacuum assembly. The reservoir assembly has a wheeled chassis and an integral reservoir. The reservoir has a circumferential sidewall and an upper end. The reservoir defines an interior space for holding a fresh cleaning liquid; and the reservoir upper end defines an opening. The reservoir assembly further has a spigot fluidly connected to the reservoir interior space, with the spigot having a valve adjustable between a fully open and a fully closed position. The vacuum assembly has a recovery tank and a motor assembly. The vacuum assembly is removably positionable on top of the reservoir, and is transportable on the reservoir. Each of the reservoir assembly and the vacuum assembly is operable both when the vacuum assembly is positioned on top of the reservoir, and when the vacuum assembly is separated from the reservoir.

International Classification:

F24C 1516

US Classification:

99422

Abstract:

A cooking surface for use with cooking kettles, such as outdoor grills, is disclosed. The cooking surface is made from a single sheet of stainless steel of sufficient thickness to prevent warping under normal cooking temperatures. The cooking surface has a grill section with a plurality of parallel slots cut into the stainless steel to emulate a rack type cooking surface and a griddle section that is substantially solid. Two embodiments of the combination griddle and grill cooking surface are disclosed, one directed to a rectangular kettle and one directed to a circular kettle. An adaptable embodiment of the rectangular cooking surface having extendable slide bars to fit various size cooking kettles is also disclosed.

Abstract:

In one aspect of the invention, a portable floor care system with manually interchangeable AC and DC vacuum motor head assemblies for use in cleaning hard surface flooring may include: a reservoir defining an interior space operable to hold a cleaning liquid; a spigot fluidly connected to the reservoir interior space, the spigot manually adjustable through a range between a fully open position and a fully closed position, whereby when the reservoir contains a cleaning liquid, a user may dispense and regulate the flow of the cleaning liquid from the reservoir through the spigot by manually adjusting the spigot; a vacuum recovery tank; an AC vacuum motor head assembly and a DC vacuum motor head assembly manually and interchangeably fluidly connectable to the vacuum recovery tank; and a DC power supply assembly. In another aspect of the invention, a portable floor care system with manually interchangeable AC and DC vacuum motor head assemblies for use in cleaning hard surface flooring may include a reservoir assembly including: a reservoir defining an interior space operable to hold a cleaning liquid; a wheeled chassis; and a spigot fluidly connected to the reservoir interior space, the spigot manually adjustable through a range between a fully open position and a fully closed position, whereby when the reservoir contains a cleaning liquid, a user may dispense and regulate the flow of the cleaning liquid from the reservoir through the spigot by manually adjusting the spigot. The portable floor care system may further include: a vacuum recovery tank manually and removably positionable on the reservoir assembly; an AC vacuum motor head assembly and a DC vacuum motor head assembly interchangeably manually and removably positionable on the vacuum recovery tank in fluid communication with the vacuum recovery tank; and a DC power supply assembly manually and removably positionable on the reservoir assembly.
