Definitions

  • the invention relates to a cooking, roasting or baking vessel made of metal with a separate plate provided in the base area made of a metal whose physical properties differ from the material of the vessel.
  • Cooking pots made of metal are known in a variety of designs. In addition to the enamelled pots made of carbon steel for protection against corrosion, more and more recently, corrosion-resistant pots have become
  • Chromium-nickel steel (18/10) pots are used, the bottom of which is to be placed on the stove as a rule today as a sandwich bottom, i.e. on the bottom area of the actual steel saucepan is made of a metal with good thermal conductivity and with increased heat storage capacity, i.e. plate made of aluminum or copper is soldered on, the flat side of which is to be placed on the stove plate, in order to avoid wear, can be covered by a flat, thin plate made of corrosion-resistant steel, also soldered on.
  • double-walled stainless steel saucepans are already known (CH-PS 604 643), which - in particular if the associated pot lid is double-walled - have the advantage of a significantly reduced energy consumption for a certain cooking result compared to the usual single-walled saucepans , because the heat-insulating space between the side walls of the vessel reduces losses due to heat transfer from the food to the side walls and radiation from the side walls into the environment.
  • the dishes in these vessels can also be kept warm for a longer period of time, which means that in many cases an otherwise necessary reheating can be omitted.
  • a plate is used in the base area instead of the insulating space
  • SUBSTITUTE SHEET from a metal that is more thermally conductive than the corrosion-resistant steel that is generally used for the vessels, and mainly also aluminum or copper.
  • the advantages of double-walled cooking pots have meant that, in spite of their naturally higher price than single-walled cooking pots, they have increasingly been used in the preparation of dishes on gas stoves or electric stoves with resistance heating plates.
  • Cookers have recently been developed in which the cooking material is no longer heated by transferring heat from heated heating plates or gas flames to the bottom of the cooking vessel, but rather by induction heating of the bottom of the pan itself.
  • the bottom of the pot is exposed to a magnetic field generated in an induction coil induced by an alternating current, which therefore changes its direction in time with the frequency of the alternating current.
  • alternating voltages are induced in the metal bottom of the saucepan, which generate eddy currents, which in turn - due to the loss of heat generated by them - result in the saucepan heating up.
  • the * invention has for its object to provide a cooking vessel for preparing food, ches wel ⁇ one hand with good efficiency and is rapidly heated inductively, thereby having the advantages of the known one- and double-walled cooking vessels made of corrosion resistant Edel ⁇ steel and - like this - can also be used on the usual gas or electric stoves with resistance heating plates or fields.
  • the separate metal plate is made from a preferably ferromagnetic, inductively heatable metal.
  • the vessel according to the invention is designed as a double-walled vessel, which is composed of two metal vessels, preferably of corrosion-resistant steel, which are placed one inside the other and connected to one another along their upper edges, the dimensions of which are dimensioned so differently that they enclose a heat-insulating space.
  • the configuration in a further development according to the invention is such that the plate provided in the base area is made of the inductively heatable metal.
  • the design - as in the known double-walled saucepans - can be such that the outer and the inner vessel each have a peripheral side wall which is closed by a base wall, and that the inductively heatable plate provided in the base region between the inner surface of the base wall of the outer and the outer surface of the bottom wall of the inner vessel is arranged, and that the plate is at least soldered to the outer surface of the bottom wall of the inner vessel
  • SUBSTITUTE SHEET is welded.
  • the inductively heatable base plate is hermetically sealed in the space between the vessels and thus protected against corrosive influences of moisture or also against mechanical damage.
  • an embodiment is also possible in which the outer vessel has a cutout dimensioned on the bottom wall side in accordance with the diameter of the inductively heatable plate provided in the bottom area and the edge delimiting the cutout is attached to the peripheral surface of the plate which is exposed in the cutout. A reduction in the efficiency of inductive heat generation due to the shielding of the base plate by the outer vessel is avoided in this way and heating is achieved even faster.
  • the configuration is preferably such that the separate plate provided in the bottom region is inserted into the top part of the vessel made without bottom and is connected along its edge to the top part.
  • This makes it possible to manufacture only the plate forming the bottom of the vessel from the inductively heatable metal, while the main part of the vessel can again be made of corrosion-resistant steel or - as is often the case with water boilers - of aluminum.
  • the separate plate provided in the floor area can thus be made of soft iron, carbon steel or a chrome steel.
  • SUBSTITUTE SHEET 1 shows a longitudinal central section through a first exemplary embodiment of a cooking vessel according to the invention in the form of a double-walled saucepan;
  • FIG. 2 shows a sectional view corresponding to FIG. 1 of a modified exemplary embodiment of a double-walled saucepan
  • FIG 3 shows a side view of a water boiler designed in the manner according to the invention, which is broken open and cut in the region of the separately used bottom.
  • the cooking pot shown in FIG. 1, designated in its entirety by 10, is composed of an inner and an outer vessel 12 or 14 of different sizes, which are punched out of corrosion-resistant steel sheet from a chromium-nickel alloy and into the pot shape shown may be pressed.
  • the vessels 12, 14 welded to one another along their upper edges enclose a cavity 16 between them, which, however, is formed in the bottom area by a ferromagnetic, e.g.
  • Plate made of soft iron is filled, which can be soldered to the underside or outer surface of the bottom of the inner vessel 12 and the top or inner surface of the bottom of the outer vessel 15 in order to - good heat transfer - in particular from the plate 18 to the bottom of the inner Vessel 12 and thus on the food - to ensure.
  • the insulating cavity 16 existing between the side walls of the vessels 12 and 14 largely precludes heat losses through the side wall of the saucepan 10.
  • the aim of reducing heat losses is also served by the double-walled lid 20, which is not essential in the context of the present invention, with which the saucepan 10 is tightly closable during the cooking process, and which also has a good insulating effect due to the double-walled construction.
  • the embodiment of the saucepan 10 'shown in FIG. 2 largely corresponds to the saucepan 10 described above in connection with FIG. 1, so that it suffices to only point out the differences between the two exemplary embodiments below, while for the rest reference was made to the description of FIG. 1 can be.
  • the main difference between the saucepan 10 'and the saucepan 10 is that the outer vessel 14 has no continuous bottom wall, but is cut out in this area in a size corresponding to the bottom plate 18, i.e. has a circular cutout 22 in which the underside of the ferromagnetic plate 18 is exposed.
  • the lower edge of the outer vessel 14 is soldered or welded to the peripheral wall of the plate 18.
  • FIG. 3 shows a water kettle, designated in its entirety by 110, as an example of a single-walled cooking vessel, which is made from a sheet metal, e.g. the dome-shaped upper part 112, which is used to a large extent for cookware today, and a separately punched-out top part 112, which is stamped out and provided with stiffened circumferential annular beads 114, which forms the bottom of the water boiler 110, forms the outer plate 116 thereof Edge is held by the folded or flanged free edge 118 of the upper part 112.
  • the edges of the upper part 112 and the bottom plate 116 can be hermetically sealed to one another by soldering or welding.
  • the bottom plate 116 of the kettle 110 is - unlike the upper part - made of a pure, i.e. no chromium steel containing nickel as an alloy component
  • SUBSTITUTE SHEET manufactured and therefore has ferromagnetic properties, ie it can be heated inductively.
  • the boiler 110 corresponds to the known water boilers, i.e. it has a pouring spout 120 attached to the upper part 112, which can be closed by the schematically indicated whistle 122 for the acoustic notification of the cooking process.
  • a handle bracket 124 attached to the upper part 112 allows the kettle 110 to be handled comfortably, which, moreover, also has a relatively small diameter filling opening closed by a cover 126 on its upper side.
  • this fill-in opening can also be omitted, as in the case of a large part of the known water boilers, since the filling of the boiler 110 is also possible through the pouring spout 120.

Abstract

La région du fond d'un récipient (10) pour faire bouillir, rôtir ou cuire des aliments, et fabriqué en métal, par exemple en acier spécial résistant à la corrosion (acier chrome-nickel 18/10), comporte une plaque séparée (18; 116) realisée dans un métal ayant des caractéristiques physiques différentes de celles du matériau du récipient. Cette plaque métallique (18) séparée est réalisée dans un métal de préférence ferro-magnétique et chauffable par induction, par exemple du fer doux, de l'acier carboné ou de l'acier chromé, de sorte que le récipient s'utilise non seulement sur les cuisinières à gaz ou électriques traditionnelles à plaques chauffantes à résistance, mais également sur des cuisinières à induction.
