Definitions

  • the invention relates to a system comprising a worktop and at least one functional element that can be arranged on an underside of the worktop. Furthermore, the invention relates to a work table comprising such a worktop and a method for producing such a work table.
  • Worktops of systems of the type in question here can be designed, for example, as cooktops which have functional elements on their underside that serve as heating devices or display devices. Due to the particularly attractive appearance and the simple handling and cleaning, corresponding worktops are often made of glass ceramic. Glass ceramic has the advantage that it has a high permeability to heat radiation, an extremely low coefficient of thermal expansion and a low thermal conductivity.
  • Display devices such as illuminated display elements or light markings, which are arranged underneath the worktop as part of an electronic control, must be arranged with small tolerances to markings or recesses in coatings on the worktop.
  • Heating elements for example induction coils or radiant heaters or under-glass gas burners, which are arranged below the worktop as part of a heating device, are to be arranged with small tolerances towards markings or recesses in coatings on the worktop.
  • the markings can indicate, for example, the location and size of a hob or a cooking zone.
  • gas burner inserts provided in recesses in the worktop must be arranged as centrally as possible to the gas burners in the substructure, so that narrow tolerances must also be observed here.
  • Inductive charging points or energy coupling points for example for mobile devices or small kitchen appliances, which are arranged below the worktop as part of power electronics, for example as part of a hob power control, must be positioned as precisely as possible to mark or cut out coatings on or under or in the worktop.
  • sensors such as communication sensors, for example IR sensors for interacting with extractor hoods, or temperature sensors, for example IR semiconductor sensors for measuring the temperature of pot bases, or brightness sensors for determining the brightness of the room, which are arranged below the worktop as part of an electronic control system, must also have said tolerances to markings or recesses of coatings on or under or in the worktop.
  • ventilation or ventilation devices for example integrated steam extraction devices, which are to be aligned as closely as possible to countertops in the worktop.
  • the carrier is designed as a drawer, so that the functional elements can be inserted under the worktop.
  • the carrier is designed to be foldable. Thus, the support provided with the functional elements can be folded under the worktop.
  • the present invention is therefore based on the object of designing and developing a system of the type mentioned at the outset in such a way that the structurally simple means enable the functional elements to be positioned exactly in relation to the worktop. Furthermore, the task is based on a work table and a method for producing a Specify work table that can be set up with little effort and in compliance with the necessary tolerances. Another task is to provide an alternative system, an alternative work table and an alternative method for producing a work table.
  • the above tasks relating to the system are solved by the features of claim 1.
  • the system in question then comprises a worktop and at least one functional element which can be arranged on an underside of the worktop, characterized in that the worktop has at least one first centering means, that the functional element has at least one second centering means and that the first centering means and the second centering means are designed to correspond to one another in such a way that the functional element can be arranged in a defined position relative to the worktop.
  • the worktop and the functional element have centering means that correspond to one another.
  • at least one first centering means is provided on the worktop and at least one second centering means is provided on the functional element.
  • the first and the second centering means work together in such a way that the functional element is arranged in the desired, precisely defined position relative to the worktop.
  • the construction described also makes it possible to mount the functional element or a plurality of functional elements independently of the worktop, for example in a substructure. Since the functional elements are thus not necessarily fixed on the underside of the worktop, they can be exchanged extremely easily in the event of a defect or if the functionality of the system is to be adapted.
  • a plurality of functional elements can be provided, each of which has a separate second centering means.
  • at least some of the functional elements can have one or more common second centering means and can thus be positioned together in relation to the worktop.
  • the worktop can be made at least partially or completely from glass and / or from glass ceramic.
  • Appropriate worktops are particularly easy to handle, especially easy to clean.
  • the size of the worktop can be of any design, a size of at least 0.3 m 2 , preferably of at least 0.7 m 2, being particularly advantageous. Worktops with such a size are particularly suitable as kitchen worktops or laboratory worktops and have an attractive appearance.
  • the worktop can have a marking and / or a recess in a coating at the position at which the functional element is to be arranged.
  • it can be the marking of a hob and / or an operating element or the like.
  • the coating can in particular be designed as an opaque coating, which serves to define a display window.
  • the positioning of individual secondary or second functional elements can also be determined by design specifications, for example a symmetrical arrangement with respect to one another, or by ergonomics such that the positioning of individual second functional elements is based on at least one primary or first functional element. In this case, the positioning of the second functional elements is not determined by local markings or recesses in a coating in the vicinity of the second functional element, but is based on the positioning features of a first functional element.
  • the functional element can be designed as a light indicator and / or as a heating element, for example as an induction coil, radiant heater or gas burner.
  • the functional element can be designed as an energy transmission element, in particular as an inductive charging point, and / or as a sensor element, in particular as a capacitive control sensor or IR control sensor.

  • the first centering means and the second centering means can be formed as part of a tongue and groove connection.
  • the centering means can be made longer, for example to implement a frame-like construction.
