Elongated steamhead for a steam bath

Abstract

The dispensing chamber of the steamhead is mounted between the studs within the wall of a steam bath enclosure. The chamber is isolated from the environment and includes an elongated steam outlet extending outwardly from the chamber, through an opening in the wall. The rectangular outer edge of the outlet is flush with the interior surface of the wall and is the only portion of the chamber visible from inside the enclosure. The outer edge of the outlet is shaped to coordinate with the appearance of a linear drain. It also allows the steam to be dispensed over a wider area. The outlet has a steam flow capacity greater than the steam flow capacity of the inlet such that steam expands within the chamber as the velocity of the steam is reduced. Internal baffles reduce noise. Light sources may be associated with the chamber.

DETAILED DESCRIPTION OF THE INVENTION

(8) As depicted in the drawings, the present invention relates to a steamhead including an elongated dispensing chamber, generally designated A, designed for use in a residential or commercial steam bath and adapted to be installed within the wall of a steam bath enclosure, generally designated B.

(9) Dispensing chamber A improves the distribution of the steam throughout the steam bath enclosure. It functions as a manifold, allowing steam to expand as it passes through the chamber. At the same time, the chamber functions to reduce the velocity of the steam.

(10) The chamber includes a front wall 10, a rear wall 12, a top wall 14 and a bottom wall 16. Walls 10, 12, 14 and 16, along with the sides of the chamber, define an interior space which is isolated from the environment.

(11) Top wall 14 has a centrally located round steam inlet 18. An internally threaded fitting 20 may be mounted on top wall 14 in alignment with steam inlet 18, as shown in the drawings. Fitting 20 is fabricated to receive the externally threaded end of a feed pipe or conduit (not shown) connected to receive steam from a steam generator (not shown). Alternatively, the rim of top wall 14 which defines steam inlet 18 may be internally threaded to receive the end of the steam generator feed pipe, thus eliminating the necessity for the fitting.

(12) Chamber A also includes an elongated steam outlet 22 extending outwardly from front wall 10 for a distance equal to the thickness of the wall of steam bath enclosure B within which the steamhead will be located. Because of its elongated shape and dimensions, the steam outlet 22 allows the steam to exit the chamber over a wide area.

(13) Steam outlet 22 is rectangular in shape and is defined in part by members 24 and 26 which extend outwardly from the plane of front wall 10 of the chamber and form the top and bottom of the steam outlet, respectively.

(14) Steam outlet 22 has substantially larger cross-sectional area than steam inlet 18 and thus has a steam flow capacity substantially greater than the steam flow capacity of steam inlet 18. Accordingly, chamber A allows steam from the steam generator to expand before exiting steam outlet 22 while at the same time reducing the velocity of the steam.

(15) The steamhead also has at least one, and preferably multiple, baffles 29 situated within chamber A, between steam inlet 18 and steam outlet 22. Baffles 29 define the path in which steam from steam inlet 18 must travel within chamber A to steam outlet 22. Baffles 29 reduce the noise made by the steam as it moves through the chamber.

(16) As illustrated in FIGS. 1 and 5, the front wall 10 of chamber A has an interior surface 28. One set of baffles 29a extend from surface 28 into chamber A. The rear wall 12 of chamber A has an interior surface 32. A second set of baffles 29b extend into chamber A from surface 32. As best seen in FIG. 5, surface 28 faces surface 32 such that the baffles 29a and the baffles 29b extend in opposite directions, toward each other.

(17) Baffles 29a are spaced from each other. Likewise, baffles 29b are spaced from each other. Baffles 29a are vertically offset from baffles 29b such that the baffles from the respective baffle sets 29a, 29b are interleaved with each other, creating a circuitous path through which steam must travel as it expands and moves through chamber A from steam inlet 18 to steam outlet 22.

(18) Bottom wall 16 is inclined toward steam outlet 22 such that any water which accumulates at the bottom of chamber A will be caused by gravity to flow towards and exit through steam outlet 22.

(19) In addition, the upper surface of at least one of the baffles 29, and preferably all of the baffles 29, is inclined toward bottom wall 16. Thus, gravity will cause any water which accumulates on the upper surfaces of the baffles 29 to eventually flow down to wall 18 and out of steam outlet 22.

(20) Each of the sides of chamber A is sealed with a rubber gasket 36. Each gasket 36 is held in place by an end cap 38 which is situated adjacent to the gasket. Each end cap 38 has mounting portions 40 extending upwardly and downwardly beyond the top and bottom walls of chamber A, respectively. Each mounting portion 40 includes openings 42 adapted to receive screws for mounting the steamhead to a structural member.

(21) As seen in FIG. 6, end caps 38 permit the steamhead to be securely mounted between the vertical studs 41 within wall 43 of steam bath enclosure B. Preferably, chamber A is sized to fit between conventionally spaced studs.

(22) As seen in FIG. 2, the steamhead is mounted within wall 43 of the steam bath enclosure instead of inside the enclosure, as is the case with conventional steamheads. Members 24, 26, and the forward portions 44 of end caps 38, define the rectangular outer edge of steam outlet 22. The plane of the outer edge of the steam outlet is situated in substantially the same as the plane of the interior surface of wall 43 of the steam bath enclosure B. Thus, as seen in FIGS. 2 and 6, when installed, the outer edge of the steam outlet is substantially flush with the interior surface of wall 43. The only physical portion of the steamhead which is visible from inside the steam bath enclosure is the rectangular outer edge of the steam outlet.

(23) As is best seen in FIG. 1, the steamhead is formed of two extruded parts 46, 48. Part 46 includes front wall 10, top wall 14, baffles 29a and member 24 which forms the upper portion of the steam outlet. Part 48 includes bottom wall 16, rear wall 18, baffles 29b and member 26 which forms the lower portion of the steam outlet.

(24) The chamber parts 46, 48 and end caps 38 (with gaskets 36) are assembled to form chamber A. The end caps 38 are attached to each of the chamber parts by screws and function to retain the chamber parts together.

(25) Top wall 14 includes a downwardly extending member 50 situated at the rear the thereof. Rear wall 12 has a channel 52 shaped to securely to receive member 50 and to seal the front wall and the rear wall together, when the chamber parts are assembled.

(26) The chamber parts are preferably composed of anodized aluminum.

(27) One or more light sources 54 may be associated with the steamhead. The light sources may take the form of a single LED or a cluster of LEDs. Preferably, one light source is located at each end of chamber A to provide even light distribution through steam outlet 22, as seen in FIG. 6.

(28) An opening is created in each of the end caps 38, and in the aligned gasket 36, in order to accommodate a light source which extends into the interior of the distribution chamber. Each light source is connected to the control circuitry of the steam generator or to a temperature sensor associated with the dispensing chamber. Accordingly, the light source can be energized when the steam generator is operational or when the temperature of the dispensing chamber exceeds a predetermined level.

(29) Multiple light sources 54 may be employed. The light sources may emit different color lights. For example, one light source may emit a red light to indicate that the steam generator is operating or that the temperature of the dispensing chamber is above a predetermined level and may emit steam. Another light source may emit a different color light (green or blue) indicating that the steam generator is not operational or that the steam generator is not operational or that the temperature of the dispensing chamber is below a predetermined level and will not emit steam.

(30) Alternatively, the light sources may take the form of ultraviolet LEDs which generate light at a wavelength which kills bacteria.

(31) Because of the high temperature within the dispensing chamber, high temperature ceramic packaged LEDs fabricated to withstand the steam temperatures could be used if properly sealed against moisture. However, to avoid that problem, the LEDs may be situated remotely from the dispensing chamber so they are not exposed to high temperature. In that instance, light emitted from the LEDs could be transferred to the interior of the chamber by means of light pipes which extend through the end caps of the chamber.

(32) While only a single preferred embodiment of the present invention has been disclosed for purposes of illustration, it is obvious that many modifications and variations could be made thereto. It is intended to cover all of those modifications and variations which fall within the scope of the present invention, as defined by the following claims.
