Definitions

  • the invention relates to electrical dishes according to the preamble of patent claim 1.
  • electrical dishes are understood to mean, in the broadest sense, electrically heated containers and the like for food preparation, the heating of which is integrated in the container.
  • the bottom of the container is provided with a resistance heater that serves as a heat source.
  • the applied voltage can take any values, in practice these are between 12 V and 400 V.
  • the well-known kettle is a very widespread electrical tableware.
  • the purpose of a kettle is to only bring the water to a boil and not to keep it at a certain temperature level. As soon as the water has reached the boiling point, overtemperature protection ensures that the device is switched off.
  • Similar conditions also apply to the electric fryer, which is used to heat a certain amount of oil, usually to no more than 200 ° C.
  • a radiator that can often be swung out is placed near the bottom of the fryer.
  • the food is usually placed in a chrome-plated frying basket and immersed in the hot oil.
  • the heat source is also inside the fryer.
  • Heating the electric fryer which is installed outside the deep-frying container, is certainly a poorer solution in an energetic sense.
  • a heat source is here a tubular heater that is completely wetted by the oil and, on the other hand, any other solution would certainly be more expensive.
  • the invention has for its object to provide a mobile cooking unit with which you are able to meet your cooking needs independently of a stationary stove.
  • the weight of such a cooking unit should be kept as low as possible, because if this were not possible, the well-known solution Rechaud and Topf would be sufficient.
  • FIGS. 2-8 different alternative embodiments of the invention.
  • FIG. 1 The basic structure of an electrically heated pot according to one embodiment of the invention is shown in FIG. 1.
  • a very suitable layer consists, for example, of aluminum oxide, which can be produced cheaply by electrochemical means.
  • a resistance layer 4 is applied to this well electrically insulating, but also good heat-conducting layer.
  • Such a layer can cover several Be produced in a manner, for example by PVC or CVD deposit or by screen printing and subsequent baking.
  • a heating foil can be used. All of these heat sources have very low heat capacity, respectively.
  • -Inertia and give their heat to the pot base part 2 by contact, ie heat conduction.
  • a thermal insulation 5 is arranged below the pan base provided with the heat source, which is held for example by means of a holder or counter plate 6.
  • the space 7 serves to have enough space for the electrical connections.
  • the use of electrically insulating ceramics such as aluminum nitride, silicon nitride, aluminum oxide and silicon carbide is also advantageous. There is no need for a dielectric here, since electrical insulation is already present.
  • a variant is shown in FIG. 2.
  • the pot base plate 8 takes over the function of the pot base part 8.
  • the pot base plate 8 is on the one hand the pot base itself and on the other hand it also serves as a heat source because it carries the resistance layer 4.
  • Ceramic, insulating material with good thermal conductivity properties can be replaced by metallic materials. Compared to the ceramic version, the risk of destroying the bottom plate 8 of the pot is substantially reduced.
  • the operational safety of the electrical dishes is further increased by the construction shown in FIG. 3.
  • the advantage of this solution is that when the ceramic or metallic base is destroyed, the food, which can be very hot, cannot escape from the cookware. This largely prevents accidents.
  • Ceramic or metallic heating plates, which serve here as pot base plate 8 are firmly connected to the pot base part 2. This connection can preferably be made by soldering, gluing, etc. The higher operational reliability is paid for by a slight loss in terms of energy consumption, the parboiling time and the reaction speed compared to the version in FIG. 2.
  • FIG. 4 Another constructive solution of the connection of the heating plate to the pot base part is shown in FIG. 4.
  • Their advantages are that in practice it is often very difficult to establish a connection 9 that is reliable over a very long lifespan of a pot (residual stresses and shear forces often lead to signs of fatigue and destroy a soldered connection sooner or later).
  • FIG. 4 there is a reliable solution which is oriented towards a very long service life.
  • the heating plate and the bottom of the pot do not occur here, since a compensation medium is provided between the heating plate and the bottom of the pot 2.
  • the compensation medium 11 does not have to be electrically insulating, which allows the use of all thermal pastes, mercury, salt or molten salt or a low-melting metal (wood metal, rose metal, etc.).
  • a spacer 10 is attached between the pot base part 2 and the pot base plate 8.
  • the function of the spacer 10 is to keep a certain distance between the pot base part 2 and the pot base plate 8 and thereby to prevent contact between the two parts takes place. If they touch, there is a risk of deformation of the base plate 8 of the pot.
  • An outer jacket 12 serves to connect the pot base plate 8 to the vessel wall 1.
  • the resistance layer 4 is to be applied to the top of the heating plate, then it is covered with a further dielectric 13, as shown in FIG. 5.
  • Layers such as preferably aluminum oxide and other electrically insulating layers with reasonably good thermal conductivity properties are very suitable for this. Thermal insulation 5 is recommended when good energy conditions should be achieved or when working on heat-sensitive substrates.
  • an electrical cookware can also be used as a simple cookware, which is used by a conventional hotplate, e.g. Mass hotplate, radiant heating or inductively heated.
  • a conventional hotplate e.g. Mass hotplate, radiant heating or inductively heated.
  • Fig. 7 shows a particularly preferred version of the electrical dishes, which best meets today's expectations.
  • the pot is thermally insulated downwards when it is used as electrical dishes by placing a spacer plate 10. If you remove the spacer plate 14, you can heat up the same pan in a conventional manner on a hotplate.
  • the spacer plate 14 is designed as an easily assembled element. A simple snap-snap connection has proven itself well.
  • FIG. 8 shows a version which does not differ in its functional part from the version in FIG. 7.
  • the only difference from the solution in FIG. 7 is that the resistance layer 4 is accommodated on the base part 2 of the pot.
  • the bottom part of the pot 2 is first provided with an electrically insulating layer so that the resistance layer 4 can be applied thereon.
  • the function of the dielectric 13 is to prevent contact between the pot base part 2 and the resistance layer 4 and thereby cause a short circuit. This measure is purely a safety measure, especially when one takes into account that the compensation medium 11 is not only good heat conductor, but also electrically insulating.
  • a resistance layer can only be applied to an electrically conductive substrate if a dielectric has been applied beforehand. Where there are electrically insulating resistance layer substrates, a dielectric is of course not required.
  • Each resistance layer carrier material is preferably equipped with at least one, usually with several, temperature sensors 15. In this way, the temperature conditions are recorded and made available to a controller (not shown).
