Abstract

The invention relates to a scraper (1) including means (4) for spraying onto a surface through a hole (41) and a scraper body (5) with a resilient scraping element (6) having an edge (7) that is used to scrape a smooth surface. The invention is characterised in that, close to a face (9) of the scraping element (6), the body (5) includes liquid-collection means (10) on a substrate (11) which can absorb residual liquid and is connected to a pipe (20), said liquid-collection means including an end surface (40) that can come into contact with the aforementioned face (9). The invention also relates to a household appliance including one such scraper (1).

Abstract

The invention relates to a vacuum cleaner (100) in which drawn-in particle-laden air flows between an inlet nozzle (3) and a hole (119) communicated with a suction chamber (60). The vacuum cleaner is characterised in that it includes a water/air separator (1) disposed between an upstream pipe (2) and suction means, which can direct the gaseous phase into the suction chamber (60) and the particles into a container (22). The invention also relates to a heating body (201) built into the vacuum cleaner (100) and characterised in that it comprises a filament embedded in ceramic materials and a spray chamber (135) formed by a helical space between two bodies or casings (134; 137) nested inside one another, at least one of said bodies or casings (134; 137) taking the form of a ceramic body containing an embedded metal filament (130; 140).

Abstract

The invention concerns a liquid-gas mixing device, forming a safety valve, designed to be incorporated in a gas cleaning installation comprising a liquid tank (4), an inlet (1) feeding gas flow to be cleaned and an outlet (7) via which the gas is evacuated. The invention is characterized in that it comprises: a tube (2) sliding about the supply inlet (1) and including a peripheral float (8) arranged around its lower end and designed to float in said tank (4), said sliding tube (2) being open in its lower part to suck in the liquid from said tank (4) by venturi effect and generate a mist in the expansion region (5); a mixing chamber (6) interposed between said sliding tube (2) and said outlet (7), and designed to channel the flow of said mist towards the bottom of said tank (4).

Abstract

The present invention relates to a mobility device (100) for a domestic or industrial cleaning appliance (1), comprising at least one obstacle bypass means (200) positioned on at least one portion of the periphery of the vacuum cleaner (1) and serving as a bumper, said obstacle bypass means (200) comprising at least one movable part consisting of a strip (5) which is mounted free to rotate in a plane parallel to the plane of movement of said appliance (1) and which is placed so as to protrude with respect to the body of the appliance. It is characterized in that it comprises means (300) for rotationally guiding said strip (5) that are designed to be able to be fitted onto the outside of a shell (20) belonging to said appliance (1).

Abstract

The present invention relates to a liquid/gas separator (1), especially for a vacuum cleaner, comprising on the one hand an upstream pipe (3) and a downstream pipe (4) connected through a communication orifice (9), and on the other hand, mounted so as to be rotatable inside either pipe, a gas-permeable filtration means (5) designed to direct the in-drawn liquid to its periphery by centrifugation. The separator is characterized in that said filtration means (5) forms means of closing said communication orifice (9).
