Abstract

A washbasin having a basin and a steam generator. The basin has a drain and a basin steam outlet. The steam generator has a water inlet, a tank configured to store water received at the water inlet, a heater configured to heat the water to generate steam, and a generator steam outlet configured to output the steam. Coupling elements couple the steam generator to the basin and a steam outlet conduit fluidly connects the generator steam outlet to the basin steam outlet. The basin steam outlet is located on a rear wall of the basin.

Claims (41)

1. A washbasin comprising:

a basin comprising a drain and a basin steam outlet;

a steam generator, the steam generator comprising:

a water inlet;

a tank configured to store water received at the water inlet;

a heater configured to heat the water to generate steam; and

a generator steam outlet configured to output the steam;

coupling elements which couple the steam generator to the basin; and

a steam outlet conduit fluidly connecting the generator steam outlet to the basin steam outlet;

wherein the basin steam outlet is located on a rear wall of the basin.

2. The washbasin of claim 1 wherein the steam generator is suspended from the basin.

3. The washbasin of claim 2 wherein the basin further comprises a front portion opposite the rear wall of the basin, the steam generator suspended beneath the front portion of the basin.

4. The washbasin of claim 1 further comprising a second basin steam outlet, a second steam outlet conduit, and a second generator steam outlet, the second steam outlet conduit fluidly connecting the second generator steam outlet to the second basin steam outlet.

5. The washbasin of claim 4 further comprising a central plane, the basin being symmetric about the central plane, and wherein the steam outlet conduit and the second steam outlet conduit are symmetrical about the central plane.

6. The washbasin of claim 4 wherein the generator steam outlet and the second generator steam outlet are fluidly coupled within the steam generator.

7. The washbasin of claim 1 wherein the basin comprises a hole extending through the rear wall of the basin, the hole receiving the basin steam outlet.

8. The washbasin of claim 1 wherein the basin steam outlet is located above a mid-plane, the mid-plane extending parallel to a top edge of the basin and located halfway between the top edge of the basin and the drain.

9. The washbasin of claim 1 wherein the steam generator comprises a second heater, the steam generator configured to operate in a low mode where the heater is operated and a high mode where both the heater and the second heater are operated.

10. The washbasin of claim 1 wherein the washbasin comprises a control panel, the control panel spaced and isolated from the basin and the steam generator.

11. A method of generating steam, the method comprising:

providing a washbasin, the washbasin comprising a basin and a steam generator coupled to the basin;

generating steam within the steam generator;

transmitting steam from a generator steam outlet of the steam generator to a basin steam outlet via a steam outlet conduit, the basin steam outlet positioned on a rear wall of the basin.

12. The method of claim 11 wherein the step of transmitting further comprises transmitting steam from a second generator steam outlet of the steam generator to a second basin steam outlet via a second steam outlet conduit.

13. The method of claim 12 wherein the basin further comprises a central plane, the basin being symmetric about the central plane, and wherein the steam outlet conduit and the second steam outlet conduit are symmetrical about the central plane.

14. The method of claim 12 wherein the generator steam outlet and the second generator steam outlet are fluidly coupled within the steam generator.

15. The method of claim 11 wherein the steam generator is configured to operate in a low mode and a high mode, the low mode generating a first volume flow rate of steam and the high mode generating a second volume flow rate of steam, the first volume flow rate being less than the second volume flow rate.

16. A washbasin comprising:

a basin comprising a drain, a basin steam outlet, a front portion, and a rear portion, wherein the front portion and the rear portion located on opposite sides of the drain;

a steam generator, the steam generator comprising:

a water inlet;

a tank configured to store water received at the water inlet;

a heater configured to heat the water to generate steam; and

a generator steam outlet configured to output the steam;

coupling elements which couple the steam generator to the basin; and

a steam outlet conduit fluidly connecting the generator steam outlet to the basin steam outlet;

wherein the steam generator is suspended beneath the front portion of the basin by the coupling elements, the steam outlet conduit extending from beneath the front portion of the basin to the basin steam outlet.

17. The washbasin of claim 16 wherein the coupling elements comprise a first bracket, a second bracket, and a plurality of fasteners.

18. The washbasin of claim 17 wherein the coupling elements are directly coupled to the basin and to the steam generator.

19. The washbasin of claim 16 wherein the basin steam outlet is located above a mid-plane, the mid-plane extending parallel to a top edge of the basin and located halfway between the top edge of the basin and the drain.

20. The washbasin of claim 16 wherein the basin further comprises a rear wall, the basin steam outlet located on the rear wall of the basin.
