washing dry scrubbing machine

Abstract

A washing and drying scrubbing machine comprising a rotating roller brush (1) whose surface is covered by bristles (1') facing upwards and toward the center near the front of the rotating roller brush (1); 1) is covered by a structure (2) whose lower edge extends downwards and near the ground, the lower edge being provided with "tabs" (F) comprising some Align the opening (3). At the side of the housing (2) facing the ground, some sprayers (4) are aligned, the sprayers (4) being supplied with a water-detergent mixture pumped from a tank (6). Arranged near the sprayers (4) are a number of compressed air diffusers (7) which prevent the sprayed washing mixture from expanding outside the contours of the structure (2) and only towards the openings (3) and the rotating roller brush ( 1) Conveying, or conveying only on and not beyond the trajectory along which the washing and drying scrubbing machine travels. Dirty water collected by the rotating roller brush (1) is conveyed to the tank (12) by means of: a separator (8) for retaining high-consistency dirt, an intermediate container (9) comprising twin helical screw brushes (10) converging towards the center and Suction line (11). The compressed air supplying the diffuser (7) is generated by a fan (14) whose suction port arranged inside the tank (15) sucks and collects the dirty water collected by the rear parabolic floor mop (16) .

Description

technical field [0001] The invention relates to a washing-drying scrubbing machine provided with a containment and guidance system on the front side for the flow of washing mixture introduced on its operating trajectory. Background technique [0002] It is known that washing-drying machines currently on the market are basically equipped with a box-type pump assembly for a water-detergent washing mixture that can be dispersed near the washing unit comprising disc-shaped flat brushes, or small-diameter Adjacent to the pair of counter-rotating cylindrical brushes, the box pump assembly is combined with a rear receptacle intended to collect solid objects (eg, debris, etc.). The wash mix from the tank is conveyed near the said rotating brush and the dirty water and small debris is conveyed into the separator container which keeps them falling back to the floor, the muddy water scraped laterally by the curved rubber belt is pivoted The floor mopping is guided and conveyed by the ...

Problems solved by technology

Another disadvantage lies in the fact that current washing-drying sweepers exhibit a poor operational flexibility and a poor drying capacity especially and mainly in bends and in crowded or small rooms at the same time. In places and rooms, the operator has to follow a path constrained by the overlap of the cleaning tracks and has to perform wide turning radii to avoid accidents due to the lack of containment systems for spraying the washing mixture and due to the protruding of the tracks due to floor mopping. leaving wet marks, also need to pay attention to the mop protruding transversely to the track in order to avoid collision with possible protruding obstacles

[0008] Another disadvantage lies in the fact that in the presence of waterproof floors with more or less water-absorbing areas, the operator has to manually correct the flow of washing liquid, where cases of inaccurate adjustments are unavoidable, which reflects On the final quality of proper cleaning

[0009] Another drawback that exists in fact is that the current floor mop lowers itself and rubs against the floor in a pivoting manner by means of a lever arm that produces a change in the inclination of the rubber body in the presence of a sag or a hole vibrations, thereby altering its detergent action; moreover, in the presence of areas with large amounts of water, the device has to reduce the feed rate considerably, given the current suction methods with high concavities and restricted air flow in order to allow the treated surface to dry sufficiently
