Abstract

The present application relates to a steam device comprising a steam generator ( 60 ), at least one steam vent ( 37 ) through which steam is emitted from the steam device, a steam path ( 50 ) between the steam generator ( 60 ) and the at least one steam vent ( 37 ). The steam path ( 50 ) has a base ( 53 ) along which scale is able to pass. The steam device also comprises a noise generator ( 60 ) configured to act on steam generated by the steam generator ( 60 ) to generate noise. The noise generator ( 60 ) is spaced from the base ( 53 ) of the steam path ( 50 ) so that scale is not obstructed by the noise generator ( 60 ).

First claim

The invention claimed is:

1. A steam device comprising
a steam generator,
at least one steam vent through which steam is emitted from the steam device, and
an essentially elongate steam path between the steam generator and the at least one steam vent, the steam path having a base along which scale is able to pass,
wherein the steam path is formed by an upper face of a soleplate panel, a left peripheral sidewall, and an internal sidewall, and wherein a second section of said upper face of the soleplate panel defines said base of the steam path,
wherein the steam path is essentially parallel to the longitudinal length of the upper face of the soleplate panel,
wherein the steam device comprises a noise generator configured to act on steam generated by the steam generator to generate noise to provide an indication as to whether steam is flowing in the steam device,
wherein the noise generator is spaced from the base of the steam path so that scale is not obstructed by the noise generator.

2. The steam device according to claim 1 , wherein the noise generator is disposed along the steam path.

3. The steam device according to claim 1 , wherein the noise generator comprises a flow disturber configured to disrupt the flow of steam.

4. The steam device according to claim 3 , wherein the flow disturber is a steam flow splitter configured to separate the steam flow into at least two streams.

5. The steam device according to claim 4 , wherein the steam flow splitter is formed by a member extending in the steam path.

6. The steam device according to claim 3 , wherein the steam path comprises an upper face opposing the base, wherein the flow disturber extends from the upper face.

7. The steam device according to claim 6 , wherein the flow disturber defines a cavity.

8. The steam device according to claim 3 , wherein the noise generator comprises at least two flow disturbers.

9. The steam device according to claim 8 , wherein the dimensions of at least one flow disturber differs from the dimensions of the other at least one flow disturber.

10. The steam device according to claim 3 , wherein the flow disturber comprises a channel separator extending along the steam path to form an auxiliary steam channel.

11. The steam device according to claim 3 , wherein the noise generator comprises a steam reverberation chamber communicating with the steam path.

12. The steam device according to claim 11 , wherein a chamber edge forms the flow disturber.

13. The steam device according to claim 12 , further comprising a flow stabiliser configured to stabilise the steam flow and direct the steam flow towards the flow disturber.

14. The steam device according to claim 11 , wherein the steam reverberation chamber is configured to form a resonating chamber.

15. A steam device according to claim 1 , comprising a steam head, a base unit with a liquid reservoir, and a water path, wherein the steam generator is in the steam head and the water path fluidly communicates the steam generator with the liquid reservoir.
