This patent concerns surface cleaning devices in general and in particular it refers to a system for the hot cleaning of surfaces provided with a heating device for the cloth in microfibre and/or other material suitable for surface cleaning installed on the support of the same cloth.
From EP 1795109 is known a steam generator comprising an external casing with an opening that enables the inner space to communicate with the space outside. Moreover, the steam generator can be equipped with a feeding element that supplies water to said inner space, with a heating element foreseen in the opening to generate steam, an exhaust pipe whose one end is connected to the outside space to discharge steam, and a means for the control of the steam discharge on the other end to open and close the pipe outlet depending on the presence or absence of the steam to be discharged.
From EP 0842631 A is known a steam-operated cleaning device comprising a boiler equipped with heating means, steam release means connected to said boiler, and a cleaning tool comprising a foot and a handle so that said boiler and said steam release means are positioned in said foot.
The purpose of this invention is that of creating a surface hot cleaning system having a different construction from the one disclosed by the state of the art, i.e. EP 1795109 A and EP 0842631 A.
The special characteristics of the invention can be summed up in the following advantages:
As an explanation, without limitations, of the characteristics of this invention, an example of realisation of the system is now described with reference to the drawings enclosed:

From the tank (3) the water is sucked by means of a manual and/or electric pump (4) with pre-set suction quantity and then the water flows through a pipe (19) to the distribution chamber (7).
Said chamber is equipped with pipes for water flow and distribution (8), through the holes of the heating panel (11) to reach the cleaning cloth (16).
The heating panel consists of a metal element, preferably aluminium (9), which hosts a heating element (14). The panel is provided with holes for water flow (11). Said panel is equipped with a thermostat (12) suitably calibrated that keeps the heating panel temperature constant at the pre-set degree.
The water quantity is regulated by a manual and/or electric pump (4) controlled by the lever of the handle grip (6) by means of a connection element between the lever and the pump (22) and the water flows in through a pipe (19) and gets into the distribution chamber (
The cleaning cloth (
Since the entire surface of the cleaning cloth is in direct contact with the heating panel, the cloth gets to a very high temperature around 100° C. and the water coming from the holes on the heating panel moistens and goes through the cleaning cloth, thus acquiring the temperature of the same heating panel.
Thanks to this process, the cloth cleaning and sanitising action on the floor is extremely effective and homogeneous because it is carried out at a temperature around 100° C. kept constant by the heating panel provided with a thermostat that adjusts the temperature, whose action guarantees that even the most difficult dirt is removed as well as the sanitising action that eliminates germs and bacteria.
The total lack of scale build-up insures unlimited life to the device unlike all other steam systems that cannot be used after a short period of time because of scale build-up.
Energy saving amounts to about one third in comparison to any other device thanks to the fact that the entire surface of the cleaning cloth is warmed up, i.e. where it is actually necessary and there is no loss of heat, unlike the temperature produced by steam that cannot keep its temperature and therefore is less effective because it has to get through cold surfaces. The system production costs are limited because it consists of a few elements unlike any other device for steam generation, whose costs are much higher because of the great number of components and their assembly.
