ELECTRIC HEATER I OR VLJIQUYII'QS I Application tiled January 20, 1928. Serial No. 248,159.

The present invention refers to a new apparatus or electric element for the heating of liquids in general, suitable at homes for heating water for the bath or the kitchen, as well as in industries and laboratories, for simple heating, pasteurization, etc.

The apparatus is characterized by the special combination of the elements that constitute it and the simpleness of its construction.

It consists in. a circular unit of any suitable sectional form having tubes located within, forming various passages for the liquid, in combination with an electric resistance, destined to radiate the heat to a suitable temperature that can be graduated at ones own will by means of a rheostat.

The degree of temperature desired to be obtained at the outlet of the liquid, as well as the quantity of same, depends on the degree at which said resistance has been filled and the desired portions given to the apparatus can, if so desired, combine two, three or more elements or groups of elements installed in a form so as to Work in series or in quantity.

Furthermore as will be seen, the advantages ofered by this heating apparatus on those known till now, consist in l. Total utilization of the heat.

2. Easily changeable electric resistance.

3. Adaptable to different uses.

, 4. Of easy construction and therefore, economical.

5. Reduced volume, continuous functioning and graduable at ones own will, in quantity as well as temperature.

For the better understanding of this description, we accompany detailed drawings, in which:

Fig. l, represents, in central longitudinal section an electric heater for liquids, constructed according to this invention.

Fig. II, is a plain projection of same.

Fig. III, is a transversal cut, practised according to line A-B of Fig. I.

In said drawings, 1 is the external casing having located in its interior the tubes '2 and 3, as well as the electric resistance 4, suitably connected with the binding posts 5 and 6, by

means of the cover 7 of insulating material.

In the casing 1, the inlet and outlet mouths 8 and 9 are communicated, which are to be combined, when installing them, with common connecting switches or flanges.

Between the casing 1 and wall of tube 2, is a separation at the inferior or bottom part of the device, and an annular space longitidinally divided by the partitions 10 and l The interior of the tube 3 is longitudinally r The circulation of the liquid through the f apparatus is clearly shown by means of arrows in Fig. I.

Under the same system, without altering the principle of the invention, adding more partitions 12 in the central tube and more partitions of the type 10 and 11, between the covering, a coil of greater length could easily be established, but in the private experiments we have found out that in. practice, the type represented, bearing in .mind the quantity of liquid circulating in same, is more than suficient for homes, industrial establishments and laboratories for utilizing the heat radiating a common resistance, reaching temperatures up to 100 centigrade or more, if it is desired, although normally, the outlet temperature required is 40 to 60 centigrade. Havin now described and specified the nature o our invention and the .manner in which it is to be performed, what we claim as our exclusive property and invention is:

Electric heating apparatus for liquids, comprising in combination, a container comprising inner and outer concentric chambers for the passage therethrough of the liquid to be heated; electric heat generating means arranged between said inner and outer in one of said chambers extending from the bottom thereof to a point neark its upper end, the'partition in the other of said chambers extending from the upper end thereof downwardly to points near the bottoms of v said chamberjand so constructed and arranged as to compel the liquid to be heated to How in close proximity tothe Walls of` saidchambers adjacent to said heat generating means throughout its passage ,through said container.
