Definitions

  • the invention relates to a stove with hob, preferably a glass ceramic hob, equipped with cooking level input elements, hotplate control, digital display and optionally a pan detection logic.
  • Cookers with hobs which will preferably be glass ceramic hobs, have, in addition to input elements, display elements and, if appropriate, devices which are suitable for pan detection on the respective hob.
  • Both electronically operated digital displays and pan detection components are costly assemblies that should be operated by only one electronic hotplate control if possible.
  • the object of the invention is therefore to electronically supplement a hotplate control so that this control, in addition to the power control of the hotplates, can optionally be operated with parboiling electronics and the digital display and pan detection.
  • the solution to the problem according to the invention is characterized in that the hotplate control which can be selected on the input side by cooking level input elements feeds a data bus for heating power control, a data bus for digital display and a data bus for pan detection on the output side. wherein the hotplate control corresponds to an interface electronics.
  • Advantageous embodiments of the invention are contained in the subclaims. An embodiment of the invention is described below with reference to the drawing.
  • the figure shows a basic circuit diagram of the hotplate control with associated peripherals.
  • a hotplate controller 1 a digital display 2, a pan detection 3, an interface for the digital display 4 and an interface for the pan detection 5, cooking level input elements 6.1, 6.2, 6.3 and 6.4 and a data bus for heating power control 7 can be removed.
  • the figure corresponding to the solution according to the invention clarifies that the circuit arrangement consists of three essential assemblies: “hob control with power control and parboiling electronics", “digital display”, “pan detection logic”. These modules are connected via special interface electronics. This interface electronics is designed so that both the hotplate control alone, the hotplate control with the digital display and the hotplate control with digital display and pan detection logic can be operated. This makes it possible to optimally divide the modules between the cooker and the hob, while avoiding unnecessary costs with maximum flexibility.
  • the interface electronics between the hotplate control and the pot detection is designed in such a way that the hotplate control automatically recognizes the presence of the saucepan detection and thus offers the additional function "saucepan detection".
  • the interface electronics leave the operating modes "hotplate control without additional option", “hotplate control with digital display” and “hotplate control with digital display and pan recognition ". If the information on the pot available on the hotplate is transmitted to the hotplate control by the electronic interface, this releases the power output to the selected hotplates. This function takes place without additional electronic costs, since the hotplate power is transferred from the hotplate electronics Relay is controllable. If no pot is placed, the hotplate control switches off the heating output of an already selected hotplate in correspondence with the interface electronics.
  • the interface electronics In correspondence with the hotplate control, the interface electronics also perform the additional function that the pan detection logic is limited in time by a special operation for each hotplate After a predetermined time, the pan detection switches on again automatically.
  • the hotplate control in correspondence with the interface electronics leaves the digital display flash for signaling if the pan detection logic does not recognize a pan on the selected hotplate.
  • the flashing signal in the digital display can be supplemented by an additional acoustic signal that gives the user the information that a hotplate is still switched on, which is not intended for use.
  • pan detection logic it can be expedient to render the pan detection logic ineffective, for example when it is a matter of using dishes that are unsuitable for pan detection on a hotplate shown above. Since no separate switch units are used to switch off the pan detection, for example for design and cost reasons, this function is achieved by selective, multiple selection of the cooking level input elements. With such a prescribed input procedure it is therefore possible to bridge the pot detection logic, whereby for security reasons this may only be effective for a certain time, for example three hours. The bridging of the pot detection logic is clad with a flashing display symbol in the digital display.
