Abstract: The invention relates to a scraper, including a device for projecting-onto a surface through an opening, and a scraping body with a resilient scraping element including a ridge capable of scraping a smooth surface. The body includes, towards a surface of the scraping element, a device for collecting liquid on a substrate absorbing residual liquid connected to a conduit. The device for collecting has an end surface-capable of entering into contact with said surface. The invention also relates to a household appliance incorporating such a scraper.

Abstract: The invention relates to a vacuum suction and cleaning apparatus comprising a nozzle (38), ventilation means (40), a clean water tank (20), an air-water separator (50), a recovery tank (4) for soiled liquid and/or dirt, a handle (5) for manipulation with one hand, a heating means (19) using a ceramic for electrical and thermal insulation. It is wherein the separator (50) comprises a brush (2) driven in rotation, that prolongs the ventilation means (40), rotating with a turbine (11) or nozzle (51) serving as support, and that the apparatus (100) comprises an air evacuation hose (6) incorporated in the handle (5) prolonging a by-pass, and that the recovery tank (4) is located under the separator (50).

Abstract: The present invention relates to a vacuum cleaner, in which circulates a flow of drawn-in air loaded with particles, between an inlet nozzle and an aperture communicating with a suction chamber. The vacuum cleaner includes a water-air separator intercalated between an upstream conduit and suction device, capable of orienting the gas phase into the suction chamber, and the particles into a tank. The invention relates to a heating body incorporated in the vacuum cleaner. The vacuum cleaner also includes a filament embedded in ceramic materials, and a spray chamber formed by a helical space between two bodies or casings nested into each other, at least one of the bodies or casings being a ceramic body incorporating, embedded, a metallic filament.

Abstract: This invention relates to a gas-liquid mixing device, forming a safety valve, designed capable of being incorporated into a gas-cleaning installation including a liquid tank (4), an inlet (1) for gas to be cleaned and an outlet (7) through which the gas flow is evacuated. It is characterized in that it has: a tube (2) sliding around the gas inlet (1) and including a peripheral float (8) located in its lower end and designed capable of floating in said tank (4), said sliding tube (2) being open in its lower portion, in order to draw liquid from said tank (4) by a venturi effect and to create a mist in a pressure-relief zone (5); a mixing chamber (6) interposed between said sliding tube (2) and said outlet (7), and designed capable of conveying the flow of said mist towards the bottom of said tank (4).

Abstract: This invention relates to a liquid-gas separator (1), namely for a vacuum cleaner, including, on the one hand, an upstream conduit (3) and a downstream conduit (4) connected through a communication opening (9) and, on the other hand, mounted mobile in rotation inside either conduit, filtering means (5), pervious to gas, and designed capable of conveying by centrifugation the liquid collected at its periphery. It is characterized in that said filtering means (5) constitutes means for closing said communication opening (9).
