Definitions

  • the invention relates to a cooking unit, in particular for commercial kitchen stoves or the like, with a hotplate, for example made of glass ceramic, which is provided on its rear side with at least one radiant heater which has an insulating body with at least one radiant heating element.
  • the invention has for its object to provide a cooking unit of the type mentioned, which ensures simple assembly when the radiant heater is securely connected to the hotplate.
  • the glass ceramic plate can also be attached to the hob by itself, after which a number of radiant heaters corresponding to the number of hotplates to be provided on the hob are attached as separate assemblies. This can be done easily lead to assembly errors, it being particularly important when using radiant heaters as heating that the insulating body rests securely against the underside of the hotplate, which is achieved with the aid of the springs which are usually inserted or arranged during assembly.
  • the training can be significantly simplified by not providing support brackets running across the underside of the radiant heater, but by the support being formed by at least one support frame extending from the hotplate to the rear of the radiant heater, in particular formed by an angled profile, which grips the radiant heater on the back only in the associated edge area, so that the cooking unit takes up very little space, especially at height.
  • the spring can also be located between a leg of the carrier that engages around the back of the radiant heater and the back of the radiant heater, so that it is completely covered and space-saving only a very small spring extension is required in the spring direction, which makes it possible to use relatively hard springs.
  • the radiant heater is set down on the back in the area of the support surrounding it, preferably in such a way that the back of the radiant heater lies outside the offset area approximately in one plane with the surrounding part of the support.
  • the spring is on a cover made of sheet metal or the like provided on the insulating body.
  • supported which, in contrast to a shell-shaped cover receiving the insulating body, is preferably formed by an approximately flat base plate leaving the insulating body free on the outer circumference, so that there is a further simplification in construction.
  • This base plate expediently has the same layout as the insulating body, so that its outer edge surface is flush with its outer peripheral surface.
  • This cover is also advantageously suitable for forming a holder for a connection body for the electrical connection of the radiant heater within the outer circumference, in particular in the area of a central cutout, which is substantially completely sunk inside the insulating body or a central one in the latter provided cutout may lie.
  • the carrier expediently over the outer circumference or the respective outer edge of the insulating body continuously going through.
  • a high mechanical strength of the self-contained assembly is achieved if the carrier forms a frame surrounding the radiant heater.
  • the carrier can be connected to the hotplate in an extremely simple manner in that it is heat-resistant to the hotplate, e.g. is glued with a silicone adhesive.
  • the carrier is expediently completely within the outer edges of the hotplate, so that the gluing takes place only on the underside of the hotplate.
  • a supporting edge can be provided, which is likewise advantageously bonded to the support or to the hotplate or to both parts by gluing. is attached.
  • this is expediently carried out in relation to its associated edge surface.
  • the supporting edge engages under the support, in particular its outwardly directed leg, so that the supporting edge forms a support for the support and thus also for the hotplate lying directly above it.
  • the spring can in a simple manner as a leaf spring, wave spring, bow spring, plate spring or the like. be trained.
  • a hotplate of the cooking unit for forming a plurality of separately switchable hotplates located adjacent to one another within a hob can also have a corresponding number of separate radiant heaters, each of which is provided with at least one radiant heating element arranged in a carrier shell and forming a heating field and is pressed against the underside of the heating plate, supported on springs on a substructure.
  • Electric cookers for cooking large quantities of food as is regularly the case in commercial kitchens, canteens and other facilities, generally have electric hotplates with hotplate bodies made of cast iron, which are inserted into a hob, as the cooking areas.
  • Such stoves have proven themselves in many respects, but there is still a need for even easier handling, even lower energy consumption with faster responsive provision of power and easier maintenance or repair than, for example, that in GB-PS 714 373 known stove is the case.
  • the invention is therefore also based on the object to provide a cooking unit of the type described, which makes it possible to create continuously seamless use areas with substantially seamless and liquid-tight design of the hotplate, which can be heated so that one or more of them Numerous different thermal images can be set with regard to the heating.
  • each radiant heater in one to its outside Measurements-adapted receptacle of the substructure is inserted essentially immovably and that the receptacles are almost immediately adjacent to one another in such a way that the hob is essentially seamless and can be heated to at least about 85% of its total area.
  • the hob is the one that is bounded by the outer boundaries of an associated group of radiant heaters, such that the hob can be larger than this hob.
  • each radiant heater can be operated independently of the other radiant heaters due to its regulation or control and based on its technical data, so that the radiant heaters can be set so that the cooktop is provided by seamlessly interconnecting or thermally merging heating fields of the same or different power is formed and cooking vessels can be transferred by moving or moving both into the desired heating field alone and into zones in which two or more adjacent heating fields are effective with different proportions depending on the position of the cooking vessel.
  • the hotplate Due to the almost complete juxtaposition of the radiant heaters in a non-displaceable position, the hotplate can be supported so well by the support shells, which are usually provided with damping insulating material on the underside, even with a relatively large overall dimension on the underside, that the hotplate hardly breaks even under the toughest conditions is to be feared.
  • all radiant heaters are square, in particular square, and preferably only connect with slot-like gaps of the order of at most a few centimeters, in particular approximately one centimeter wide. It is particularly advantageous if all radiant heaters are of the same design and, for example, are interchangeable, although it is conceivable to provide different radiant heaters with regard to the nominal power and with regard to the control or regulation, but which expediently have the same layout dimensions, so that, for example, four, one rectangular or radiant heaters forming a square hob are provided.

  • the recordings can be formed in a simple manner by angular profiles, on the approximately horizontal legs of which the radiant heaters are supported independently of one another by spring elements, so that for each radiant heater a backlash-free and tight system can be achieved on the underside of the hotplate with a low overall height of the cooking unit.
  • the hotplate can expediently be removed or lifted off from the radiant heaters or from the cooking unit, which results in a very simple operation if the hotplate can be opened and when it is brought into its operating position by placing it on upper end faces of the outer edges of the carrier shells of the radiant heaters Preload of the spring elements presses down.
  • a particularly advantageous development of the subject matter of the invention is that the respective radiant heater is switched via a temperature controller, so that there is rapid operational readiness, i.e. heating with the highest possible output and nevertheless low energy consumption in the unloaded state, i.e. in the case in which no heat is removed by a cooking vessel, which results in a good power adjustment, which can be further improved, for example, by the continuously adjustable design of the temperature controller.

  • the detection sensor l34 is expediently surrounded by, for example, a truncated conical insulating jacket l35, which can extend to further support the plate lO6c to its underside or, as shown in FIG. L8, has a small gap distance from the plate lO6c.
  • the insulating jacket l35 lying within the field l33 sits on the bottom of the insulating shell l22c as a separate part, but can also be formed in one piece with the insulating shell l22c.
  • the insulating jacket l35 can also be used to shield the plate lO6c against excessive heating in the central region of the heating field, for which reference is made to patent application P 35 26 783.6 for further details.
  • the temperature sensor ll2c is shifted slightly from the center of the radiant heater lO4c to one side in such a way that it lies directly adjacent to the outer circumference of the insulating jacket l35, whereby it is additionally at least from below through the insulating jacket l35 can be supported or is non-contact with the insulating jacket l35. As also shown in FIG.
  • the sections of the radiant heating elements llOc, lllc are located next to one another with a relatively small clear distance and at approximately the same small distance from the inner surface of the outer edge l23c, these distances being at most in the order of magnitude of the spiral diameter of the radiant heating elements, in particular are at least a third smaller, so that there is a very high heating density.
  • This essential arrangement, as well as the almost seamless arrangement of the radiant heaters next to one another guarantees the entire hob very even, intensive heating, whereby the hob can be heated directly to at least approximately 90% of its total area or even more.
  • the clear helix distance is expediently about 5 mm.
  • FIG. 20 the same reference numerals are used for corresponding parts as in the figures from FIG. 9, but with the index "d".
  • the two radiant heating elements llOd, llld are arranged in parallel in separate circuits, a radiant heating element llOd being switched via a contact l36 of the temperature controller ll3d actuated by the temperature sensor ll2d.
  • a switch l37 designed in the manner of a power control device is placed on the temperature controller ll3d in such a way that it can be actuated via the same setting button ll4d as the temperature controller ll3d.
  • the switch l37 has at least one additional contact l38, which is closed via the area of the setting of the setting button ll4d which corresponds to the higher temperature setting area of the temperature controller ll3d. Additional contact l38 is open in the lower area.
  • the switch l37 has an isolating contact l39, which is closed in addition to the switch-off position of the setting button ll4d or the temperature controller ll3d and, in this switch-off position, is used for all-pole separation of the radiant heating elements llOd, llld from the current source l4O.
  • the additional contact l38 is arranged in the circuit of the second radiant heating element llld.
  • the additional contact l38 could also be part of the temperature controller.
  • the isolating contact l39 there is a switching contact l4l influenced by the detection sensor l34, which is open when the heating field is unoccupied and closes on the heating field when a cooking vessel is set up.
  • This solution also offers the possibility for the automatic preparation of dishes, ie when the temperature controller is set to a temperature corresponding to continued cooking, a high heating power is initially released when a cold saucepan is placed on the pan, which is then reduced to continued cooking power as the temperature of the food or cooking vessel increases.
  • a major advantage of temperature control is therefore that with a given temperature setting there is a higher power release as soon as a cold cooking vessel is placed, whereas the output drops as soon as the cooking vessel is removed and the heating field is operated in idle mode.
  • the rear radiant heaters are then expediently set to a boiling temperature so that the cooked dishes can be cooked on them by moving the cooking vessels on the hotplate from front to back.
  • An advantageous adjustment of the control or regulation of the radiant heating elements can be provided, for example according to FIG. 2l, such that when the setting knob 114d is set, in which it has been rotated by 90 ° from the switch-off position, a temperature of approximately 90 ° on the heating plate C is given. After a further rotation of, for example, approximately 90 degrees to 180 °, a temperature of approximately 30 ° C. is obtained, with the radiation heating element llld being switched on via the additional contact l38 when the adjusting knob is turned further, so that a temperature of over 500 ° C. can be reached .
