Definitions

  • the invention relates to a hob with a glass ceramic plate, at least one cooking zone with assigned heating device, a power supply line and an electronic device with electronic control and switch for power setting of the heating device.
  • the invention therefore has the problem of being equipped with an electronic control To create cooktop, which both optimal protection against wired and external interference, as well as against incorrect operation and also a Easily reduced losses in standby mode. In addition, a trouble-free cleaning of the hob is retained.
  • the mains disconnector consists of a, underneath the glass ceramic plate, arranged reed contact, which is movable by a on the glass ceramic plate Magnet is switched.
  • the formation of the magnet is of particular importance. If it is hinged and / or slidably attached to the frame of the hob, it is a simple one Cleaning of the entire glass ceramic plate guaranteed.
  • Another advantageous embodiment shows an embedding of the magnet in a housing, for example made of plastic, whereby the magnet is particularly protected against contamination and its functional reliability is guaranteed.
  • An advantageous handling of the mains disconnector results from the Design of the magnet as a sliding or rotating device. It is a switch on the Reed contact by rotating the entire housing with an internal magnet as special to look advantageous.
  • FIG. 1 shows an open hob (1) with a plurality of heating elements (2.1 to 2.4).
  • the glass ceramic plate arranged above the heating elements (2.1 to 2.4) has been dispensed with, around the heating elements (2.1 to 2.4) and the arrangement of the voltage supply line (3), components (4) for conversion and stabilization into a DC voltage and Make the power controller (5.1 to 5.4) more recognizable.
  • the power controllers (5.1 to 5.4) are arranged together in a side area next to the heating elements (2.1 to 2.4).
  • the hob (1) is connected to the power supply in every household with approx. 220V.
  • Components (4) are located in front of an electronic device (6) connected to the power controllers (5.1 to 5.4) so that the high AC voltage is not present at the power controllers (5.1 to 5.4), which are designed as touch sensor buttons in electronic control Conversion and stabilization into a DC voltage. After these components (4), the DC voltage reaches the electronic device (6).
  • the control signals of the power controllers (5.1 to 5.4) are passed on to the heating elements (2.1 to 2.4) via the electronic device (6).
  • a mains isolating switch (9) for voltage interruption is arranged in the voltage supply line (3) between the mains voltage (N) and the electronic device (6) and is completely covered by the glass ceramic plate (7). This mains disconnect switch (9) can be controlled from the outside by remote control or without contact.
  • a design of the mains isolating switch (9) as a reed contact is particularly advantageous for self-sufficient hobs with electronic control.
  • the electronic device (6) can be de-energized and after the voltage has been switched on again via the reed contact (9), it is reinserted into the previously defined state, ie it is automatically activated Reset ".
  • the reed contact (9) is switched via a magnet (11) above it.
  • FIG. 2 shows a hob with the glass ceramic plate (7) on which several cooking zones (8.1 to 8.4) are arranged.
  • Each cooking zone (8.1 to 8.4) is at least one heating element (2.1 to 2.4) assigned.
  • the glass ceramic plate (7) is preferably at least partially surrounded by a frame (10).
  • the heating elements are below each cooking zone (2.1 to 2.4) arranged.
  • the power controllers (5.1 to 5.4) for the heating elements (2.1 to 2.4) are designed as touch sensor buttons in electronic control. That has the Advantage that there are no openings in the glass ceramic plate. Consequently the hob can be cleaned particularly easily.
  • the one below the glass ceramic plate (7) arranged reed contact (9) by placing a magnet (11) on the glass ceramic plate (7) switched. This leads to an interruption in the voltage supply to the electronic device (6).
  • the reed contact (9) acts like a main switch that switches the entire operating elements (5.1 to 5.4) and the electronic device (6) from the mains and de-energizes.
  • the magnet (11) can be connected to the hob (1) in different ways become. It can be placed loosely on the glass ceramic plate (7) or it can be fixed or detached be connected to the frame (10) or the glass ceramic hotplate (7). Particularly advantageous it is when it is displaceable on the frame (10) or can be folded away from it is. This makes it easier to clean a hob (1) with sensor control buttons to be kept.
  • a firm connection to the frame (10) has the advantage that the magnet (11) is not removed, set aside and then not found again can.
  • FIGS. 3a to 3e show different possible variations of a housing (12) for a magnet is shown, in which the switching action is carried out by a sliding device (13).
  • the housing (12) is preferably made of plastic and takes the magnet (11)
  • the magnet (11) is located inside the housing (12) and is not shown in FIGS. 3 visible.
  • the housing (12) can be designed such that it consists of two, at least parts (12.1, 12.2) partially arranged one above the other and a housing part (12.1) from the off (0) to an on (I) position and vice versa (Fig. 3a, b, c).
  • Fig. 3a, b, c Here it is irrelevant for the function whether the movable part (12.1) in the front (12.3) (Fig. 3c), arranged in the rear area (12.4) (Fig.
  • housing (12) in one piece and an opening (12.6) to provide for the displaceable magnet (11) as a sliding device (13) (Fig. 3e).
  • FIGS. 4 a and b show housings (12) in which the switching action of the magnet (11) is realized by a rotating device (14).
  • Figure 4a shows that the rotating device (14) is arranged on the housing (12).
  • FIG. 4b shows the entire housing (12) with the magnet (11) in its interior rotatable about a pivot point (15) and switches the Reed contact (9).
  • the housing (12) has recessed grips (16) for one in the side regions better handling.
  • the housings (12) shown in FIGS. 3 and 4 are proposed solutions for an arrangement of the housing (12) in the corner area of a hob (1).
  • Execution of a housing (12) is also an insert on one of the side areas of the hob (1) possible, the arrangement of the housing (12) with the magnet (11) depends on the position of the reed contact (9).
