A FUEL ECONOMISING VESSEL

Abstract

A fuel economising vessel A fnel economising vessel comprising a plurality of protrusions of high thermal conductivity provided on the inner surface of the vessel, such that the articles or substances to be heated within the vessel are exposed to a larger areaof heatmg than the area of the said surface itself, the outer surface of the vessel being exposed to the heat source thereby conducting the heat directly, through the protrusions, to the articles or substances to be heated.

Thw invenlion relaleti lu a fu($l economising veHHel for uw in heitmg varioas articleB and substances, including fluids, solids and semi-solids, more particularly, though not exclusively, food substances. The said vessel will be provided with a lid, whenever necessary. In one case the lid will be such as to cover the vessel tightly and enable steam pressure to build up within the vessel. In such a case the lid will be provided with the usual pressure release valve. The vessel in tiiis case will serve as a pressure cooker or other autoclave. In another case, the lid of the vessel will serve to contain the steam within the vessel. The steam pressure in such a case will not be as high as that in a pressure cooker, but will still be sufficient for steam heatuig or cookmg p'urposes. In yet another case, the vessel will shnply be used forheatmg an article or substance and may or may not be covered with a lid. In the latter case the moudi of tiie vessel has necessarily to be left open to atmosphere. Vessels used for heatmg various substances, such as those indicated above, generally suifer from the drawback that there is no optimum utilisation of heat energy. For intitiuice, in a veKMel uwd for cooking food» the baite of the vessel gets heated by a heat source, that is to say, the food withm the vessel is exposed to heat over an area equal to the area of the base. Similarly, the food within the vessel is exposed to heat over an area equal to that of the mner wall of the vessel. It is therefore an object of this mvention to hicrease the base area, within the vessel, over which the food is heated, and optionally, to hicrease the area of the mner wall of the vessel to achieve better distribution of heat and greflfter efficiency in heating; without, at the same time, altering the overall size of the vessel. The fuel economising vessel, according to this mvention, comprises a plurality of protrusions of high tihermal conductivity provided on the inner surface of the vessel, such that the articles or substances to be heated widiin tiie vessel are exposed to a larger area of heating than the area of the said surface itself, Ike outer surface of the vessel bemg exposed to the heat source thereby conductmg the heat directly, through die protrusions, to the articles or substances to be heated. This invention will now be described with reference to the accompanymg drawmgs, which ilhistrate by vfvy of Example one of various possible embodiments of the vessel proposed herein, wherein Fig.l iiiuDirstoH the said embodimrat in Bevtionai elevHiion Fig.2 iltustrfttes the said embodiment in plan. Fig.3 illustrates one of various forms the protnisions can take e.g. conical. Fig.4 illustrates another of various forms the protrusions can take e.g. pyramidal And Figs.5, 6 and 7 illustrate solid, hollow and partly solid and partly hollow bodies of the protnisions. ^ 8 c^A^'^ KAM^^^V^^-^ The vessel according to the embodimettt is indicated by V. It will be seen from the drawings that the vessel comprises a phirality of protrusions P provided on the inner surface S of the vessel V. These protrusions P on the mner surface S of the vessel V resuh in the area of the mner surface S of the vehicle bemg enlarged such that the articles or substances to be heated wi&in the vessel are exposed to a larger ar^a of heating than the area of the said surface itself. > The protrusions P may have solid bodies B, hollow bodies H or partly solid and partly hollow bodies E. The same vessel may have a combination of any of the aforementioned types of protrusions on its inner surface. Each type will have a different heat transmission/detention factor. For mstance^ af^er the heat source (used in heating the vessel) is shut off, the solid body protrusions will retain heat (in themselves) for a period longer than that of the hollow body protrusions. This factor helps to retain food whhin the vewtei warm for a period longer than that of the hollow body protrusions. On the other hand, the hollow body protrusions transfer heat from the heat source to the interior of the vessel over a shorter duration than that of the solid body protrusions. The heat retentivity is less than that of the hollow body protrusions. The partly solid and partly hollow body protrusions can be said to have characteristics in between the other two mentioned above. Accordmg to the embodiment illustrated the protrusions are shown to be provided on the mner surface S of the base J of the vessel. Optionally, the protrusions can be provided on the inner surface, of the wall W of the vessel. Alternatively, the protrusions can be provided on the inner surfaces S of the base J as well as the wall W of the vessel. It will be appreciated that the terms and expressions herein are of description and not of limitation and do not exclude any equivalents of the features described and illustrated, but that there are various other embodiments of the vessel proposed herein that are possible without depiirting from the scope tuid ambit of this invention. I Claim: l.A fuel econotnisiiig vessel comprising a pfairatity of protrusions of high thermal conductivity provided on the inner surface of the vessel, such that the articles or substances to be heated within the vessel are exposed to a larger area of heatmg than the area of the said surface itself, the outer surface of the vessel being exposed to the heat source tiiereby conducting the heat directly, through the protrusions, to the articles or substances to be heated. 2.A fuel economising vessel as clahned in Claim 1 wherein a protrusion has a solid body. 3.A fuel economising vessefas clamied in Claim 1 wherein a protrusion has a hollow body. 4.A fuel economising vessel as claimed m Claim 1 wherein a protrusion has a partly solid and a partly hollow body. 5.A fuel economising vessel as claimed in any one of the preceding Claims wherein the protrusions are provided on the inner, surface of the base of the vessel. 6.A fuel economismg vessel as claimed in any one of the preceding Claims wherein the protrusions are provided on Uie inner surface of the wall of the vessel. 7.A fuel economising vessel substantially as herein described with reference to, and as ilhistrated in, the accompanying
