Definitions

  • the invention relates to a gas hob as well as a display method for a gas hob with at least a first and a second gas burner, each with an associated flame monitoring sensor which closes when a flame goes out of at least the first gas burner, a main valve which is arranged in a main gas line, located in to the gas burners leading partial gas lines, in each of which a setting element for adjusting a gas flow rate is arranged, and with a display device, which indicates the first gas burner after closing the main valve.
  • EP 0 727 616 A1 is a generic gas hob with four gas burners known. Associated with each of the gas burners is a flame monitoring sensor which, when a flame extinguishes during a burner operation, closes a main valve located in a main gas line which divides into partial gas ducts leading to the gas burners, in each of which a gas tap for adjusting a gas flow rate is arranged.
  • US-A-6,164,958 shows the features of the preamble of claims 1 and 4.
  • a variety of other sensors such as a smoke sensor, is provided. If one of the sensors detects an abnormality such as smoke, etc., a warning field displays a warning indication.
  • the object of the present invention is to provide a gas hob with gas burners and a method for display in a gas hob, in which the gas hob is reliably operated even with a faulty extinction of a flame on a gas burner.
  • the object of the invention is achieved by a gas hob or by a method having the features of claim 1 and the features of claim 4.
  • the characterizing part of claim 1 shows an analog display device of the gas hob after closing the main valve not only the gas burner whose flame is extinguished, but also all other gas burner whose Adjustment elements are in an open position.
  • the display device By the display device, a user receives the indication which gas burners were in operation until the flame went out. Their adjustment elements, the user can first bring into a closed position to reliably avoid unwanted gas leakage from the gas burners. Subsequently, a subsequent gas hob operation can safely take place.
  • the display device displays each gas burner, whose adjusting element is in the open position, until its adjusting element is in the closed position again.
  • the display device can only display the gas burner whose flame has extinguished.
  • the user receives the reference to the defective gas burner only after all adjusting elements of the gas burners in the open position are in the closed position again.
  • gas hob has four schematically indicated gas burner 1, 3, 5, 7, which are guided by a cover plate 9 of the gas hob.
  • the gas hob On the front side, the gas hob has a control bar 11.
  • a gas knob 13 15, 17, 19 is arranged for each of the gas burners.
  • each of the gas burners is associated with a display 21, 23, 25, 27, which is in each case designed as an LED.
  • the operation of the gas hob is based on the block diagram of the FIG. 2 described.
  • the block diagram is the FIG. 2 limited to the gas burner 1 with the associated control knob 13 and the fault indicator 21.
  • the other gas burner 3, 5, 7 are in a corresponding manner in the Gas hob interconnected.
  • For flame monitoring is the gas burner 1 according to the FIG. 2 associated with an ionization electrode 29, with the presence of a flame of the burner 1 is detected.
  • a gap between the flame ionization electrode 29 and the gas burner 1 can be electrically bridged, whereby a corresponding signal is passed from the ionization electrode 29 via a signal line 31 to an electronic control device 33.
  • the electrical control device 33 is connected via a further signal line 35 with a main valve 37 in connection.
  • the main valve 37 is arranged in a main gas line 39, which is coupled to a gas supply network.
  • the main valve 37 is connected to a distributor pipe 41, from which partial gas lines 42 each lead to the gas burners 1, 3, 5, 7.
  • FIG. 2 only the gas path to the gas burner 1 is shown completely.
  • a gas cock 45 is arranged, with which a gas flow rate to the gas burner 1 is set.
  • Its switching shaft 47 is connected via a shift linkage 49 with the rotary knob 13.
  • a signal generator 51 is connected between the shift linkage 49 and the rotary knob 13.
  • the signal generator 51 detects a rotational position of the rotary knob 13 and outputs it via a line 53 to the electronic control device 33.
  • the fault indicator 21 of the gas burner 1 is controlled.
  • the control knob 13 is first rotated from its zero position, in which the gas tap 45 is in a closed position. This initial rotation is detected by the signal generator 51, which passes a corresponding signal to the electronic control device 33. Subsequently, the electronic control device 33 opens the normally closed main valve 37, so that via the main gas line 39 and the partial gas line 42, a gas flow rate is supplied to the gas burner 1. At the same time, the electronic controller 33 controls the ionization electrode 29 to ignite the gas burner 1. An adjustment of the gas flow rate to the gas burner 1 by means of the gas tap 45. Its flow cross section can be changed accordingly via the control knob 13.
  • the LED display 21 is permanently switched on.
  • FIGS. 3a to 3c is the control bar 11 with the control knobs 13 to 19 and the displays 21 to 27 shown.
  • the control knob 13, 15, 17 are rotated from its zero position.
  • the associated LED displays 21 are permanently lit, so that it is clear to the user that the gas burners 1, 3, 5 are in operation.
  • the control knob 19 of the gas burner 7, however, is in its zero position and its associated LED display 21 is turned off. That is, it is clear to the user that the gas burner 7 is out of operation.
  • the electronic control device 33 controls the LED displays of all gas burners 1, 3, 5, whose gas taps 45 are still in an open position after closing the main valve 37.
  • the control device 33 activates the LED displays 21, 23, 25.
  • the LED displays 21, 23, 25 therefore start to flash, as in FIG FIG. 3b should be indicated. This gives the user an indication of which gas burners have been in operation until the flame of the gas burner 1 extinguished or the gas taps 45 which gas burners are still open.
  • the still open gas taps 45 must first be returned to their closed position. As long as this is not the case, the gas burners 1, 3, 5 associated LED displays 21 to 25 continue to flash. After all gas taps 45 by means of Control knob 13, 15, 17 are brought into their closed position, only flashes the LED display 21, which is associated with the gas burner 1, as shown in the Figure 3c is shown. This gives the user an indication that the flame on the gas burner 1 is defective.
