  • Patent number: 6287108
    Abstract: The method allows accurate setting of the volumetric gas flow through a gas feed line to a burner nozzle of a gas-operated cooking or baking appliance and required for a desired burner heat output. A corresponding cooking or baking appliance, in particular a gas stove, gas cooker, a gas hob, or gas oven, has a burner with a nozzle connected to the gas feed line. A gas valve is arranged in the gas feed line. The accuracy and reproducibility of the setting of the volumetric gas flow is improved owing to the fact that a current flow (actual measured value) of the gas through the gas feed line is detected by means of a meter and is regulated to a calculated or preset desired flow value that corresponds to the desired burner heat output by means of a controller and an actuating device for varying the gas flow.

  • Patent number: 5938425
    Abstract: A device and a method for the controlled reduction of the gas flow Q fed to a burner nozzle of a gas-fired cooking or baking appliance via a gas supply pipe. The gas supply pipe is branched into a number n of partial gas pipes connected in parallel, through which a partial gas flow Q.sub.k with k=1,2,3, . . . ,n can be fed to the burner nozzle in each case, and which have a control unit in each case, the control units each being connected on their gas inlet side to the gas supply pipe and on their gas outlet side to the burner nozzle, and have a switching element for switching on and off the partial gas flow Q.sub.k passing through them and a throttle element for reduction of the partial gas flow Q.sub.k passing through them. The switching elements can be switched on and off according to the selected heating power. Alternatively a number n of throttle elements are connected in series with switching elements connected in parallel.

  • Patent number: 5528015
    Abstract: An electric range top has a cooking surface with at least one hotspot and a display-and-control panel for the cooking surface. The panel accommodates display devices and manually operated control devices for regulating each hotspot. The cooking surface has a cutout in one corner wherein the panel is mounted. One area of the cooking surface is elevated and at least partly overlaps the cutout and the display and control devices are positioned in the vicinity of the elevated area.
