Title:
HOT CLEANING SYSTEM FOR SURFACES
Document Type and Number:
WIPO Patent Application WO/2013/179328
Kind Code:
A1
Abstract:
This invention is a new system of surface hot cleaning comprising a handle with a handle grip provided with a lever, a water and/or detergent tank, a pump and a brush. The brush is provided with a swivel head hosting the water pipe and an electric cable for the power supply of a heating panel equipped with a heating element and a thermostat for temperature regulation. Said heating panel is in direct contact with the cleaning cloth so as to warm up the cloth, which is moistened by the water flowing from the pump. The cloth acquires a high temperature ideal for cleaning and sanitising surfaces. Moreover, the system guarantees the fast drying of the floor after cleaning.

CLAIM

1. System for surface hot cleaning comprising a handle (1) provided with a handle grip (2) and a brush (5) with a swivel head (20), comprising a water distribution chamber (7), a heating panel (fig. 3) consisting of a metal element, preferably aluminium (9), which houses a heating element (14) and is provided with holes (1 1) for water flow, and a cleaning cloth (16) and at least one thermostat for temperature regulation (12) set to keep the pre-set temperature of the heating panel constant, said brush (5) having a central opening for a water pipe (19) to supply water to the heating panel (fig. 3) through the holes (1 1) and an electric cable (21) for the power supply of the heating panel (fig. 3), characterised by the fact that the handle (1) is provided with a water tank (3), a manual and/or electric pump (4), and a lever (6) to control the pump (4), through a connection element (22) that connects the lever (6) to the pump (4) to pump out water from the tank (3) and convey it to the distribution chamber (7) of the brush (5), and to the cleaning cloth (16) through the holes (11), and that the cleaning cloth (16) is in direct contact with the entire lower surface of the heating panel (10) that warms it up to the pre-set temperature adjusted by the thermostat (12), so that the water can moisten the cleaning cloth and by flowing through it acquires the same temperature as the heating panel, and that the cleaning action is carried out at a temperature around 100°C kept constant by the heating panel (fig. 3) and that guarantees the removal of difficult dirt and a sanitising action with the elimination of germs and bacteria.

Description:
HOT CLEANING SYSTEM FOR SURFACES

DESCRIPTION

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 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 one end of which is connected to the outside 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 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 that contained in 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 fo 11 owing advantages :

- Cleaning and sanitising action guaranteed by the constant and high temperature of the cloth. - Fast drying of the surface.

- No scale build-up and therefore unlimited duration.

- Remarkable energy saving - about one third of the installed power in comparison with any other steam device.

- Limited production costs, if compared to existing systems.

As an explanation, without limitations, of the characteristics of this invention, an example of the realisation of the system is now described with reference to the drawings enclosed:

- (fig. 1 ) shows the entire invention with the handle grip (1) provided with a handle (2), the water tank (3), the pump (4), the brush (5) comprising the water distribution chamber, the heating panel and the cleaning cloth;

- (ftg.2 ref. 7) shows the section of the water distribution chamber, (fig. 2 ref. 8) shows the water pipes inside the chamber;

- (fig. 3) shows the heating panel in cross section and from above.

The heating panel (9) hosts the heating element ( 14), (fig. 3 ref. 1 1) shows the holes on the heating panel through which the water flows.

- (Fig. 3 ref. 12) shows the thermostat for temperature regulation;

- (Fig. 4 ref. 16) shows the cleaning cloth in cross section and from above. 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) into the distribution chamber (7).

Said chamber is equipped with pipes for water flow and distribution (8), through the holes of the heating panel (I I) 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 ( I I). Said panel is equipped with a suitably calibrated thermostat ( 12) 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 reaches the distribution chamber (fig. 2). Said chamber is provided with pipes (8) suitable to make the water flow through the holes of the heating panel ( 1 1) to the cleaning cloth (fig. 4).

The cleaning cloth (fig. 4) is in direct contact with the entire lower surface of the heating panel ( 10), which warms it up to the pre-set temperature by means of the thermostat ( 12) positioned on the heating panel it self.

Since the entire surface of the cleaning cloth is in direct contact with the heating panel, the cloth reaches 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 guarantees 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 wanned 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.
