Abstract

It is a new steam broom for floor cleaning with a boiler (C) for steam production connected to two ducts for steam delivery, the delivery duct (CF) for front jets and the delivery duct (C1) for lower jets and a detergent delivery duct (CD), the opening or closing of the valve (VU) for steam output from the boiler is controlled by the operation device (DA), connected to the arm (M1) of the handle (M), so that the rotation of said arm (M1) around the hinge (M′) causes the displacement of said operating device (DA), thus causing the opening of said output valve (Vu). Said boiler (C) comprises two pressure gauges (P1) and (P2), a device for jet deflection (D) shuts one or more delivery ducts (CF), (C1) and (CD) by compressing them.

Claims

1. Steam broom for floor cleaning characterised in that it comprises:

A boiler (C) contained in the main body (S) and comprising at least one heating element (R), at least one safety valve (Vs), a primary (P1) temperature gauge and/or a pressure gauge, an inlet hole (Fi) for feeding water and an outlet hole, wherein an outlet duct (Cu) is positioned, which is shut by an output valve (Vu);

A handle (M) linked to the main, body (S) by means of a fork with two arms (M1) and (M2) hinged on it by means of hinges (M′

) and (M″

);

An operating device (Da) linked to an arm (M1) of the handle (M) so that the rotation of said arm (M1) around the hinge (M′

) causes the displacement of said operating device (Da), thus opening or shutting said output valve (Vu),

Nozzles (Gf) and (Gi) for steam delivery inserted in the main body (S).

2. Steam broom as in claim 1, characterised in that said nozzles (Gf) are located in the tip, or at the font, of said main body (S).

3. Steam broom, as in claims 1, 2, characterised in that said nozzles (Gi) are located underneath said main body (S).

4. Steam broom as in claims 1, 2, 3, characterised in that said output duct (Cu) is connected to one or two ducts for steam delivery, wherein the delivery duct (Cf) takes the steam up to the front nozzles (Gf) for front jets, while the delivery duct (Ci) traces the steam to the lower nozzles (Gi) for steam jets towards the floor.

5. Steam broom as in claims 1, 2, 3, 4, characterised in that said boiler (C) comprises a switch (Dp) whose closing/opening is determined by the rotation of the arm (M2) of the handle (M) around the hinge (M″

) thus allowing the connection/disconnection of said heating element (R) to/from the electric circuit of power supply, while bypassing said primary gauge (P1), in order to keep the power supply to reach and exceed the temperature and/or pressure value set by said primary gauge (P1)

6. Steam broom as in claims 1, 2, 3, 4, 5, characterised in that said boiler (C) comprises a further secondary (P2) temperature gauge and/or a pressure gauge set at a temperature and/or pressure limit value higher than the limit value of said primary gauge (P1).

7. Steam broom as in claims 1, 2, 3, 4, 5, 6, characterised in that it comprises a cup (Sd) containing detergent and a duct for detergent delivery (Cd), which connects said cup (Sd) to one or both ducts for steam delivery (Cf) and (Ci) for front and lower jets, wherein through a Venturi, effect, i.e. reductions (TVf) and (TVi) of the sections of the ducts for steam, delivery (Cf) and (Ci), the detergent is sucked into one or both said ducts for steam delivery (Cf) and (Ci) and it is delivered mixed with steam.

8. Steam broom as in the previous claims, characterised in that it comprises a device for jet deflection (D), namely a slider suitable for shutting one, none or more delivery ducts (Cf), (Ci) and (Cd) by compressing them.

9. Steam broom as in the previous claims, characterised in that said device for jet deflection (D) does not shut any delivery duct (Cf), (Ci) and (Cd), when it is in its starting position.

10. Steam broom as in the previous claims, characterised in that if said device for jet deflection (D) is slid, it shuts the duct for steam, delivery (Ci) for the lower jets.

11. Steam broom as in the previous claims, characterised in that if said device for jet deflection (D) is fisher slid, it shuts tie duct for steam delivery (Ci) for the lower jets and the duct for detergent delivery (Cd).

12. Steam broom as in the previous claims, characterised in that if said device for jet deflection (D) is further slid, it shuts the duct for detergent delivery (Cd).

13. Steam broom as in the previous claims, characterised in that if said device for jet deflection (D) is further slid, it shuts the duct for detergent delivery (Cd) and the duct for steam delivery (Cf) for the front jets.

14. Steam broom as in the previous claims, characterised in that if said device for jet deflection (D) is further slid, it shuts the duct for steam delivery (Cf) for the front jets.

15. Steam broom as in the previous claims, characterised in that said ducts for steam delivery (Cf) and (Ci) for the jets and said duct for detergent delivery (Cd) are made of flexible silicone.
