- optical information e.g. Operator information
- Plastic parts have heretofore been used as distinguishing elements, while operator information in practice has been provided by an additional user interface, e.g. a display unit, comes.
- an additional user interface e.g. a display unit
- rings are known, which are arranged around the cooking zones of a cooking plate around. These rings are usually designed as optical fibers (optical waveguides, tubular waveguides, etc.) glued to the back of the glass ceramic hotplate and fed with light (e.g., by means of diodes or other light sources).
- induction hobs that are not illuminated by a heating element are so difficult for a user to recognize.
- US 2008/0099449 A1 discloses a hob, in which a plasma lamp is arranged below a cooking plate of an induction cooker for illuminating an upper side of the cooking plate, which is excited to shine via electrodes and a respective power source.

- the cavity is arranged in particular directly on the cooking plate, it can firstly be designed and positioned comparatively unhindered by other components, which allows a high design flexibility. Secondly, the immediate arrangement on the cooking plate allows a clear visual marking on a top of the hotplate also or just in colored or blackened hotplates.
- a hotplate can be translucent, in particular transparent or opaque.
- the cooking plate can be configured independently of the type and / or shape of the associated hob.
- one or more cavities may be arranged on and / or in a cooking plate or on and / or in a cooking zone of the cooking plate.

- One embodiment is that the cooking plate is intended for use with an induction hob.
- the induction hob can be, for example, one for an eddy current heating or energy transmission via a magnetic alternating field on a equipped with a coil for tapping the alternating magnetic field home appliance, for example, a small household appliance (toaster, coffee maker, microwave, etc.) or cooking utensils.
- the cavity may be arranged in a projection of the cooking plate, wherein this projection may also be present as a separately manufactured and inseparable then connected to the glass plate element.
- a lamp-filled cavity is at least partially (or completely) formed in the cooking plate.
- the cooking plate preferably forms a partial wall of the cavity.
- a cavity filled with a luminous means can be configured to be at least sector-wise annular, i. have a ring portion.

- At least one illuminant-filled cavity is arranged in or on (in particular concentric to) a cooking zone of the cooking plate (for example an induction hob).
- the cavity is made electrodeless with gentle processing of an existing glass plate. Then, the at least one light source present in the cavity is excited by means of an external excitation field, similar to the operating principle of a zero ground. Such an embodiment is also particularly durable and reliable.
- At least one electrode for establishing the electromagnetic, in particular magnetic, excitation field into the cavity filled with the one illuminant.
- the luminaire-filled cavity For reliable excitation of the luminous means, it is advantageous that at least two electrodes for establishing the electromagnetic excitation field are introduced into the luminaire-filled cavity. This may be particularly advantageous when an external electromagnetic excitation field is either absent or too weak, for example at a cavity located outside a cooking zone of an induction hob.
- all bulbs can be used which can be excited to illuminate by means of an electromagnetic excitation field, individually or in combinations with one another.
- the lighting means may comprise a noble gas or a combination of noble gases, since these are non-toxic and inert.
- bulbs mercury or mercury compounds, halogens, carbon dioxide, solid light bulbs such as phosphor-based bulbs, etc.
- the induction hob has at least one induction hotplate.
- an induction hob in which at least one cavity filled with at least one light source is located in the region of an area irradiated by the excitation field, in particular a cooking zone, that the at least one light source by means of the electromagnetic excitation field (including an alternating magnetic field) for Lights is excitable, wherein the electromagnetic excitation field is preferably provided for energy input into a arranged on the cooking zone home appliance, in particular cooking utensils.
- a cavity can preferably be arranged in or on a cooking zone of an induction hob so that it is excited by means of the excitation field also generated for operating the household appliance. It can be advantageous to provide or modify a coil or a group of coils used for generating the electromagnetic excitation field in such a way that they are operated at excitation frequencies for the at least one luminous means with an increased power.
- the at least one coil can be operated with different frequencies and / or powers, so that, on the one hand, the induction hob and, on the other hand, the light source in the cavity are suitably excited.
- a cavity may be arranged in a plan view on an outer edge of a cooking zone.
- the method for producing such a cooking plate comprises at least the following steps: (a) venting the cavity, preferably by means of a vacuum pump to a pressure range between 10 "1 atm and 10 " 5 atm, (b) filling the cavity with the at least one Illuminant and (c) (hermetically) sealing the cavity.
- the cavity can be previously introduced into the cooking plate, in particular by laser processing with a focal point within the cooking plate, since such a joining operation with joining surfaces can be avoided.
- Fig.1a shows in plan view from above a cooking plate of an induction hob, in which a cooking zone is delimited by an annular cavity;
- FIG. 1 b shows a sectional side view of the hotplate from FIG. 1 a with an excitation source
- FIG. 2a shows a sectional side view of a cooking plate produced by a different method in a first production step
- FIG. 2b shows a sectional side view of the hotplate from FIG. 2a in a second production step
- FIG. 2 c shows a sectional side view of a cooking plate produced by a further method.
- FIG. 1 a shows a plan view from above of a cooking plate 1 of an induction cooktop of blackened glass ceramic, in which a round cooking zone 2 with a diameter d 1 is delimited optically by an annular plate 1 present in the hotplate 1 and filled with at least one illuminant 3 of thickness d 2 ,
- FIG. 1b shows a sectional view along the section line AA from Fig.1a in side view, the cooking plate 1.
- the cavity 3 is completely made of the material of Hot plate surrounded 1, which can be achieved for example by laser processing of the hotplate 1.
- a coil (inductor coil) 4 for generating an upwardly directed (in the z direction) alternating magnetic field.
- the magnetic alternating field passes through the cooking zone 2 and supplies there a corresponding household appliance (not shown) with energy.
- the household appliance can be, for example, a cooking appliance operable in eddy current operation or a domestic appliance equipped with a secondary coil for power tapping from the alternating field, for example a cooking utensil or a household small appliance.
- the inductor coil 4 is arranged below the cavity 3, so that the cavity 3 is also fed or at least partially penetrated by the alternating magnetic field.
- the light source is ionized and emits visible light when recombined, which at least partially penetrates through the hotplate 1.
- To increase the light intensity of the cavity 3 may be provided on the underside with a permeable to the alternating magnetic field optical reflector (not shown).
- the lighting means may comprise a noble gas or a mixture of noble gases.
- the color of the emitted light depends on the type of gas charged, e.g. orange-red in neon, white-pink in helium, white in krypton, blue in argon, etc., as well as in the frequency of the irradiated field.
- the cavity 3 may be configured similarly to a no-luminescent tube.
- Luminous area (realized by the cavity 3) no separate power supply, control or wiring needed and because of the proximity to the upper surface of the hotplate 1 even when tinted hotplate 1 for the user is clearly visible.
- the light emitted by the cavity 3 can give the user an impression of the power output by the inductor 4, since the luminosity depends on the strength of the alternating magnetic field and thus the cavity 3 shines only weakly at low primary power. However, when the primary power is high, it shines brightly.
- a glass ceramic plate without a cavity is first of all machined by means of a laser processing method in which the laser is focused into the interior of the glass ceramic plate and generates the cavity 3 there.
- a through hole (not shown) is created between the cavity 3 and the outside, through which the cavity 3 is vented, for example by creating a negative pressure in the range between 10 "1 atm and 10 " 5 atm by means of a conventional vacuum pump.
- a light source such as a noble gas
- the through-hole can in particular be hermetically sealed, for example by means of a glass adhesive.
- FIG. 2a shows a sectional side view of a cooking plate 5 produced by a different method in a first production step.
- the cooking plate 5 is still divided into an upper part 6 and a lower thin cover plate 7.
- an annular recess 8 has been introduced by means of a surface-removing machining method, e.g. By means of laser ablation, sandblasting, water jet machining, micro-machining, etc.
- the cover plate 7, as shown in Fig.2b placed in a subsequent manufacturing step in the direction indicated in Figure 2a arrow direction on the underside of the upper part 6 and thus fixed connected, so that forms a negative pressure cavity with the recesses 8.
- FIG. 2 c shows a sectional side view of a cooking plate 9 produced according to a further method, in which a separately produced, annular, phosphor-filled glass tube 10 is adhesively bonded to the underside.
- the embodiments shown have, inter alia, the advantages that they provide a very efficient lighting system.
- a variety of different colors can be used, which may even be variable over the frequency of the irradiated excitation field. It is also possible that the colors depend on a pressure on the surface of the cooking plate, for example by setting up a tableware.
- the arrangement with the hotplate allows a simple structure. In particular, no external or separate light sources or power sources are required except for the field generated by the coil.
- the approach presented here is not limited to the exemplary embodiments shown.
- the lamp may also contain mercury, phosphorus or other non-gaseous substances.
- the bulb is not limited to noble gases as luminous gases. For example, halogens, halogen mixtures or carbon dioxide can also be used.
- electrodes can also be introduced into the cavity.
- An excitation field can be generated between the electrodes. This is an alternative to the zero-lobe-like embodiment without electrodes and independent of a location or strength of an external excitation source. Furthermore, by means of the electrodes Blink effects, brightness or color transitions o.a. possible without disturbing normal operation.
- At least one cavity per cooking zone or per hob can be provided, if necessary, several cavities in different colors can be radiant.
