6 Claims. (01. 219-38) This invention relates to certain new and useful improvements in steam generators designed primarily for use in tailoring, laundering and like establishments.
- It has for one of its objects to produce a generator of this character which is simple, compact and inexpensive in construction, which is eificient in operation, and which is so designed as to instantaneously build up a supply of steam for pressing or like operations.
Another object is to provide an electricallyheated steam generator which is continuous and automatic in operation and which employs a novel arrangement of spray heads and associated parts for effectually converting the water into steam.
Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.
'In the accompanying drawings:
Figure 1 is a sectional side elevation of the steam generator embodying our invention. Figure 2 is a cross section thereof taken on line 2-2, Figure 1. Figure 3 is an enlarged sectional elevation of one of the spray jets and the adjoining baflie. Figure 4 is a sectional elevation of a modified form of the steam generator. Figure 5 is-a cross-section thereof taken on line 5-5, Fi ure 4. Figur 6 is an enlarged fragmentary vertical section taken on line 6--6, Figure 5.
Similar characters of reference indicate corresponding parts throughout the several views.
Referring to the embodiment of our invention shown in Figures 1-3 inclusive, l indicates a horizontally-disposed, outer cylindrical shell or casing and II indicates an inner cylinder of copper or like high, heat-conductiv material disposed co-axially thereof and in spaced concentric relation thereto to provide an annular heating chamber l2. This chamber is closed at its ends by ring-like covers l3 while the inner cylinder H, which constitutes a boiler or steam-generating chamber I4, is closed and sealed at its ends by inner and outer heads I and I6, respectively, bolted or otherwise secured to the ringcovers. Disposed within the heating chamber and coiled about the cylinder II are a plurality of electric heating coils or units I! which are connected in parallel to the domestic current supply and which serve to heat such cylinder to a. high temperature.
The inner head I5 has a sleeve or fitting l8 secured centrally thereof and connected to its outer end is a water feed pipe l9 having a check valve 20 and a hand-operated control valve 2| interposed therein. Projecting into the steamgenerating chamber l4 and connected at their inner ends to this fitting are a plurality of jet pipes 22 each having a spray head or nozzle 23 connected thereto and extending in a generally radial direction to direct the spray against the inner Wall of the cylinder II'. An angular shaped bafiie or deflector 24 extends lengthwise of the cylinder in opposing relation to the wall thereof and in correlation to the nozzles to confine the spray within a given zone or area.
The outer head It is provided centrally thereof with a steam outlet pipe 25 for delivering the steam generated in the chamber [4 to a pressing machine or like apparatus. Interposed in this pipe is a safety valve 26 and a pressure gage 21. This head also has an auxiliary steam outlet 28 therein which is connected by a pipe 29 to a water pressure boosting device 30 having a water inlet pipe 3| leading thereto and a combined water and steam outlet pipe 32 leading therefrom and connected to the water feed pipe I!) at a point in advance of the valve 2|. the apparatus is started and steam pressur is built up in the chamber l4 some of this steam is utilized to inject the water at a greater pressure to the nozzles 23 to thereby create a, fine spray or mist which, upon striking the hot cylinder wall, will be instantaneously converted to steam.
In the modification ofour invention shown in Figures 4-6 inclusive, the generator is disposed in an upright position with the main parts thereof bearing the same reference characters as in the previous construction. The numeral 33 indicates a plurality of axially-disposed jet pipes connected at their lower ends to the fitting l8, while their upper ends have spray heads or nozzles 34 connected thereto and extending radially therefrom in equi-spaced relation for directing the spray against the walls of the cylinder 1 I. Associated with each nozzle is a deflector or baflle 35 in opposing relation to the cylinder wall.
While manifestly simple, compact and inexpensive in construction, this steam generator is reliable and eflicient in operation, it generates the steam instantaneously and assures an ample and continuous supply for use with pressing and like machines, and it requires a minimum of power to operate it. Furthermore, this apparatus may be used for heating purposes and the steam outlet thereof connected to radiators.
