Definitions

  • the invention relates to a cooking or heating device with a plurality of gas burners, at least partially provided for interval operation, each of which is provided with an actuator arranged in its gas line for adjusting the gas supply and an ignition device, each actuator being provided for interval operation Gas burner an interval switching device with a clock generator and a valve controlled by the latter is connected upstream.
  • Gas cooking devices of this type are known for example from FR-A 23 08 868 and DE-GM G 80 26 873.1.
  • an electromechanical interval switching device with a solenoid valve is arranged in each gas supply line in front of the continuously adjustable tap serving as an actuator, the switching cycle of which determines the fire and time-outs of the associated gas burner.
  • a major advantage of the intermittent operation of gas burners is that in intermittent operation the heating output can be minimized without restricting the flame size and heating area. This allows dishes with low heating output to be kept warm and the risk of overheating due to Concentration of the heating power on an insufficient heating surface or on a limited tank bottom largely eliminated.
  • the installation of an interval switching device in the gas supply line of each hotplate requires considerable constructional and operational effort in the known cooking devices with interval switching.
  • the electromechanical clock used in known interval switching devices requires an external power connection.
  • the present invention has for its object to significantly reduce the structural and operational expenditure of a cooking or heating device with gas burners provided for intermittent operation.
  • the actuators of a plurality of gas burners provided for interval operation are designed as multi-way actuators and are each provided with two alternatively adjustable inlets, of which a first inlet is connected to the main gas line via the associated gas supply line and the second inlet is connected to a common clock line and that the common clock line is connected to a main gas line via the valve controlled by the clock of a single interval switching device.
  • the invention replaces the interval switching devices built into the gas supply lines of all gas burners in conventional interval switching by a single interval switching device.
  • This one interval switching device works in operation regardless of the setting of the individual actuators controlling the gas supply; because the cycle gas is supplied to each gas burner via a separate actuator path and, without prejudice to the setting of the actuator for continuous fire operation, can be clocked against the closed second inlet.
  • the invention therefore minimizes the structural outlay when equipping cooking appliances with interval switching by drastically reducing the switching and control devices. At the same time, the operational and maintenance effort is reduced and the reliability of the cooking device is increased accordingly.
  • the above advantages of cooking appliances in their intermittent operation under small and very small heat loads are used without restriction by the invention.
  • the multi-way actuator is a three-way valve, the first inlet of which is connected to the gas supply line and is associated with a throttle device for adjusting the passage cross section.
  • this throttle device can be a tapered bore in the cock plug, the flow path of which is connected to the main gas line when a cock knob is turned.
  • the three-way valve has a throttle device for adjusting the passage cross section of the second inlet connected to the common clock line.
  • a continuously burning pilot flame serves as the ignition device of each gas burner provided for the interval operation. These ensures reliable ignition at the beginning of each combustion phase after each off or rest period in interval operation.
  • the length of the time-out in interval operation is set shorter than the closing time of the thermoelectric ignition fuse.
  • the thermoelectric ignition fuse always represents the main fuse.
  • An electrical ignition device can also be combined with the interval switching device, it being controlled by the clock generator. In this way, an electrical ignition device can ensure the ignition of all gas burners instead of several continuously burning pilot lights in cyclical operation.
  • the common interval switching device like conventional interval switches assigned to each individual hotplate, can be designed as a solenoid valve and can be actuated by an electrical control device.
  • the known electromechanical actuation of the clock generator requires the connection of external energy to the gas cooking appliance.
  • the interval switching device has two magnetically interacting components, consisting of a permanent magnet and a mangeable body, which can be moved relative to one another along a common axis of movement are, a first of the interacting components forms a closing component for a valve passage opening and the second component serves as a holding component for holding the closing component in the valve opening position, that the closing component with a stop to limit its opening stroke and on the side facing away from the holding component a sealing surface for closing the valve passage is provided that the holding component is held on a membrane which allows a limited stroke movement and is pushed by a spring into an end position, the Sch let component facing one side over one adjustable throttle can be acted upon by the pressure on the valve outflow side, the arrangement being such that the pressure acting on the diaphragm side after a time determined by the throttle setting lifts the diaphragm and the holding component from the closing component and the latter
  • the device design provided according to the invention with an interval switching device common to several burners is not only applicable for gas cooking appliances, but in the same way and with similar advantages also for heating systems whose burners are intended to operate in cyclical operation.
  • Gaseous media are usually controlled;
  • the control or timing of liquid media, such as liquefied petroleum gas, is also possible in principle, but due to the significantly higher media pressure, it may require interval switching devices and actuators that are specially designed.
  • An interval switching device which is also suitable for the interval switching of media of higher pressures using a pulse solenoid valve is characterized in claims 24 to 27.
