Claims (19)
- <div class="application article clearfix printTableText" id="claims"> <p lang="en"> Claims<br><br> 1 A storage tank of a water heater including:<br><br> a side wall, a lower end and an upper end wall defining an internal storage space for the heated water;<br><br> a cold water inlet for introducing cold water into the lower portion of the tank, the inlet being connected at an outer end to an inlet port in a wall of the tank;<br><br> an outlet for withdrawing hot water from the upper end portion of the tank; and,<br><br> an inlet diffuser connected to said inlet are located at a region of discharge of cold water into the storage space in the lower portion of the tank;<br><br> the diffuser including plural spaced distribution openings which are aligned to distribute cold water into the storage space in streams emitting from the diffuser in a downward direction.<br><br>
- 2. A storage tank as claimed in claim 1, wherein the spaced openings are substantially uniform and aligned to deliver a discrete layer of cold water within a lower portion of the storage space upon withdrawal of hot water from the tank outlet.<br><br>
- 3. A storage tank as claimed in claim 1 or 2, in which the inlet diffuser includes a tube extending with a substantially horizontal direction component from the cold water inlet.<br><br>
- 4. A storage tank as claimed in claim 3, wherein said diffuser spans, in the horizontal direction, less than one quarter of a diameter of the tank.<br><br>
- 5. A storage tank as claimed in any one of claims 1 to 4, in which the plural distribution openings perforate a portion of the surface of the diffuser, that portion being subtended by an angle between 45° and 90° on either side of a vertical axis passing through the centre of the tube.<br><br>
- 6. A storage tank as claimed in any one of claims 1 to 5, wherein said plural spaced distribution openings are each smaller across its transverse axis than the diffuser inlet but in total area of openings, much larger than the diffuser inlet.<br><br>
- 7. A storage tank as claimed in claims 5 or 6, in which the cold water is distributed into the storage space as a layer spreading around a circumferential corner formed by a join between the lower end wall and the vertical wall.<br><br>
- 8. A storage tank as claimed in any one of claims 1 to 7, in which the tank comprises an inwardly domed lower end wall that extends upwardly a predetermined height into the tank<br><br> WO 02/101297<br><br> 12<br><br> PCT/AU02/00719<br><br> and the distribution openings discharge into a lowest portion of the storage space below said height.<br><br>
- 9. A storage tank as claimed in any one of claims 1 to 8, in which the inlet diffuser is curved with a radius of curvature so that no part of it touches the lower end wall of the tank while at the same time all the spaced openings are proximate the lower end wall.<br><br>
- 10. A storage tank as claimed in claim 9, wherein said radius curvature is between 100 and 150 mm.<br><br>
- 11. A storage tank as claimed in anyone of claims 1 to 10, in which the inlet and inlet diffuser are interconnected and comprise shapes and dimensions to enable both to be inserted from outside the tank through the cold water inlet port.<br><br>
- 12. A storage tank as claimed in any of claims 1 to 11, in which the cold water inlet port is between 15 and 22 millimetres diameter.<br><br>
- 13. A storage tank as claimed in any one of claims 1 to 12, including an inlet port located in the upper wall of the tank, the inlet cold water tube extending from an upper end, connected to the inlet port, to a region proximate the lower wall of the tank.<br><br>
- 14. A storage tank as claimed in any one of claims 1 to 13, wherein the diffuser extends with horizontal and radial direction components from a lower end of the inlet.<br><br>
- 15. A storage as claimed in any one of claims 1 to 14, wherein said openings are formed in such said diffuser by means of a lattice construction.<br><br>
- 16. A storage tank as claimed in claim 15, wherein said lattice construction is formed from axial and transverse members.<br><br>
- 17. A storage tank as claimed in claim 16, wherein said axial members are located on the inside of said diffuser relative to said transverse members.<br><br>
- 18. A storage tank as claimed in claim 16 or 17, wherein said axial members have a curved cross section to engage the flow of water passing out of said diffuser.<br><br>
- 19. A storage tank as claimed in any one of claims 1 to 18, wherein said cold water is emitted into the storage space in streams radiating from the diffuser, which streams travel also in a downward direction.<br><br> </p> </div>
