Definitions

  • This invention relates to cooking appliances.
  • the source of heat in the first instance will create a rising flow of air which will envelope, from both below, around and across the top, the food located within the centre part of the chamber shape.
  • Such present devices have a spherical container divided into two parts, one which is a top or a covering part, and the other which is a base and which is supported by appropriate legs.
  • the food such as a substantially sized portion of meat
  • the food can be located directly on such a mesh shelf with, however, a substantially separated tray well beneath the dish to collect molten fat lost during the cooking process and stopping this from dropping into the heat source and causing flaring.
  • the present problem with such an arrangement which provides a superior cooking technique is that it is really not appropriate in it's present form for use inside domestic dwellings and most certainly is not adapted to be located as an inbuilt fixture within a conventional domestic kitchen.
  • a cooking chamber is defined by an inner, approximately spherical space, and there are means within the space for providing support for food in an approximately central position within the space defined, the support means including a shelf adapted to extend substantially horizontally, means adapted to provide either support for burning materials to provide a heat source or providing for heat by an element being located in each case at a lowermost location within the approximately spherical space, inlet apertures adapted to provide for ingress from a lower position into the chamber, a flue means attached at or close to an uppermost part of the approximately spherical chamber to allow for egress of air from the chamber, and an access door adapted to effect an opening or closing across a corresponding aperture within the body defining the approximately spherical shape of the cooking chamber where the opening is substantially through a side of the chamber shape.
  • the shape of the door and the size of the opening in the side of the chamber, together with the corresponding size of the door, is such that, firstly, the door when closed will substantially assist in maintaining the approximate spherical or spheroidal shape of the cooking chamber.
  • the door will be swung by a hinge which ordinarily will be mounted between corresponding circumferential edges of the opening and the door, either so that the axis of the support is vertical or horizontal.
  • a surrounding body of rectangular proportions holding therewithin the chamber having the approximately spherical shape.
  • coal While coal has a number of advantages insofar that it can impart some preferred taste to the food, it also has a very significant number of difficulties. The first of these is the time that it takes to start the coal to burn reliably and then have this established before the cooking commences.
  • jetting outlets adapted to protrude within the approximately spherical chamber shape and coupled so as to insert from time to time a moisturising fluid, either in vapour or liquid form.
  • jet outlets adapted to spray water so as to be distributed across any food supported by the substantially centrally located horizontal food support tray or mesh
  • means to supply smoke and for this purpose, means to close off both the inlet and outlet apertures within the chamber and to have smoke generating means external from the chamber and adapted to pipe the smoke into the chamber and to provide for a convention flow so that at least some of the flow will be caused to pass subsequently through the vent.
  • a ducted vent can be incorporated as previously described so as to be able to be closed off or opened by a shutter passing across the opening from the vent into the chamber.
  • FIGURE 1 is a perspective view of the preferred embodiment with parts cut away showing essentially the spherical shape of the cooking chamber and the partly arcuate shape of the closure window over a side aperture of the cooking chamber, and
  • FIGURE 2 is a side elevation cross sectional view of the embodiment as shown in FIGURE 1.
  • a spherical container 1 which defines an approximately spherical chamber 2 which therefore has a substantially dome shaped upper part 3 and a lower part defined by tray 4.
  • the gas jets 5 are supported and connected to a supply of gas through conduit 7.
  • a flame diverter 8 which is located so as to extend above and outward from the respective gas jets 5 but to leave between an outer edge and the inner edge of the spherical container 1 , a substantial gap except below the aperture 9 which therefore acts to divert very hot rising air onto the hands of any person gaining access to the spherical chamber 2.
  • an open wire tray 10 which is located approximately midway within the spherical cooking chamber 2 and is supported in a substantially horizontal position thereto. It has been found that 2 and 3 such trays can be located one above the other so as to locate food in a stacked arrangement if desired.
  • An outlet 11 comprises three apertures 12 within the wall of the spherical container 1 and this is then vented to a conduit 13 which is directed into a conduit 14 which is open at both ends an upper end of which is directed into a flue 15.
  • the aperture 9 is located so as to be an aperture through the side of the spherical container 1 and such that a door 16 defining a substantially vertical plane can sealably fit so as to close the aperture 9 as desired.
  • the door in preference is supported by a set of pivotable links 17 and 18 positioned and arranged so that the door can be pulled into an open position and kept in this by being lowered while maintaining a substantially parallel alignment to a position with its upper edge at 19 contiguous with a lower edge of the aperture 9.
  • an aperture 20 which vents into a surrounding chamber 21 which in turn is vented through conduit 22 to an outlet 23.
  • Such a vent also allows for excess hot air as well arise from time to time within the surrounding chamber 21 which is defined by the outer most rectangularly shaped body 24 and the spherical container 1 , to vent also through the outlet vent 23.
  • the temperature can be significantly higher than that which normally can be used in cooking in so far that it has been found that the temperature which is reached with the arrangement described becomes very uniform throughout the cooking space so that one part of the food will not be overly heated as to compared to another during the cooking process.
  • dome shape 3 can provide for such uniform heating, there can be located significantly bigger burning gas jets, and relatively large air inlet apertures at 6 which can therefore raise the temperature accordingly.

Abstract

Le four de cuisson décrit comprend une chambre de cuisson approximativement sphérique (2), une ouverture (9) pratiquée dans un côté de la chambre de cuisson approximativement sphérique (2), une sortie d'air (11) ménagée dans une partie supérieure de la chambre de cuisson (2), une entrée d'air (6) ménagée dans une partie inférieure de la chambre (2), ainsi qu'un anneau de jets de gaz (5) pourvu d'un déflecteur servant à dévier l'air chauffé pour le faire monter autour d'un côté interne d'un récipient essentiellement sphérique (1), de façon à produire un efffet de cuisson sur les aliments placés dans une position approximativement centrale sur une grille à l'intérieur de la chambre approximativement sphérique (2).
