Abstract: A device for collecting data relating to a cooking and/or heating process performed on a hob comprising at least one sensor associated with wireless data transmission means and means for receiving the signals transmitted from the data transmission means and connected to a hob management system for the purpose of permitting automatic control of the process. The sensor is fitted substantially at one end of a kitchen utensil suitable for coming into contact with the food to be cooked and/or heated, while the data transmission means are arranged in the handle of the kitchen utensil.

Abstract: A gas cooker comprises temperature detection means for detecting the temperature of the bottom face of a pan and issuing a temperature signal and an heat control circuit for controlling the amount of heat issued from the gas burner based on said temperature signal. The temperature detection means is placed in a zone of the cooker around the burner and shielding means are provided in order to reduce the influence of the burner flame on the temperature detection means.

Abstract: A system for indicating by means of at least one warning light the residual heat of at least one pan support grid for a gas burner in domestic cooking or heating appliances controlled by an electronic control device, in which the residual heat of the grid is measured indirectly by the electronic control device on the basis of data relative to the flame level set for the burner and the time for which said flame level is maintained, these data being corrected by a factor which takes account of the physical characteristics of the grid, such that the warning light is and remains activated when the residual heat of the grid exceeds a predetermined safety threshold (A) for its handling by the user.

Abstract: Solenoid valves for controlling the gas flow to burners are controlled by an electronic microprocessor card by means of pulse-width modulated signals. The electronic card can receive signals from a timer to be set by the user, and from means by which the user selects the heat output of the burners. The first of said means to be operated by the user after setting the time makes the relative burner dependent on the timer. When the two data (time and heat output) have been set, the card extinguishes the flame of the dependent burner when the set time has expired.
