Cleaner with hot plate for floors provided with a sandwich panel for heating and gradual releasing of the water to an underlying cleaning cloth

A cleaner with hot plate for floors comprising:

• a handgrip (1),
• a handle (2),
• a tank (3) for containing water,
• a main body shaped as a brush (5), into which the handgrip (1) is pivoted by means of an universal joint (4);
• a heating plate (6) fixed below the body (5) and provided with a heating element (9) for heating the plate (6) and having a thermostat (10) for regulating temperature, as well as an electrical supplying cable (7) for the heating element (9);
• and
• cleaning fabrics (16) for the floor, applied to and supported below said heating plate (6),
• wherein said cleaning fabrics (16) are hooked below a sealing frame (13) below said body (5), said sealing frame connected to a sandwich panel (12) kept in direct contact with the heating plate (6);
• and
• wherein said sandwich panel (12) comprises at least a layer of polyurethane foam (18) having a suitable thickness and density, placed between two polyester fabrics (17) and coupled thereto, and a waterproof element (19) applied centrally to the sandwich panel (12) onto a surface coming in contact with the heating plate (6);
• the water coming from the tank (3) drains through a connection pipe (25) and at least a central passage (11) of the heating plate (6) in a scattered manner onto the sandwich panel (12), in such a way that the sandwich panel is wetted by the water drained uniformly on to the surface thereof;
• wherein said sandwich panel (12) is adapted to retain the water and heats to a same temperature of the heating plate (6);
• by maintaining the same temperature, the sandwich panel is dried at approximately 100° C. and transmits heat to the underlying cleaning fabric (16);
• and
• wherein said water tank (3) is provided with a plug (21) and a filter (22), into which a ball valve (23) is installed and is operated by gravity;
• when said ball valve is in a vertical position thereof, a water passage (24) from the tank (3) toward the connection pipe (25) prevents the sandwich panel (12) from becoming wet;
• wherein when said ball valve is in an oblique position and displaced from said vertical position thereof (23′), said water passage (24) allows the sandwich panel (12) to become wet.
