  • Publication number: 20140261007
    Abstract: A gas burner safety system comprises dual sensor arrays, the first array positioned proximal to the gas burner and the second array positioned proximal to a control used to turn on and of and regulate the flame of the gas burner. The first array senses the flame components such that a flame signature is obtained when no object is placed on or above the flame and a flame image is obtained when an object is proximal to the flame. By comparing the flame signature and the flame image, a central control unit operatively connected to the sensor arrays can determine the presence or absence of an object proximal to the flame. The second sensor array is positioned to detect a human hand proximal to the control. In operation, if the flame image matches the flame signature and a human hand is not detected proximal to the control, the central control unit turns off the gas burner by causing the closure of a valve in the gas supply line to the gas burner.

A data transceiver processing module may receive a plurality of sound waves and analyze the plurality of sound waves for a variation in frequency (or Doppler Effect) to determine if any of the sound waves originate from the one or more detector modules.

  • Publication number: 20120247443
    Abstract: A safety system for gas-operated cooking appliances which include at least one burner which is connected to the mains gas network via a distributor, the gas flow of which is controlled by a manually operated gas tap, includes a position switch, a flame detection device, an electrically controlled control valve which is installed in the mains gas network, a manually actuated restoring switch in operable communication with the control valve, and a control circuit. The control circuit is configured to open the control valve after the latter was shut off by the flame detector of the burner only when the control circuit simultaneously receives a signal from the restoring switch and the position switch. The safety system serves as a child safety measure which prevents an inadvertent re-activation of a gas flow system that has been shut off.

  • Publication number: 20120204853
    Abstract: A household gas appliance includes a gas supply valve which is operated using a magnetic key. The gas supply valve itself may be magnetically operable. In this instance, when a magnetic key is placed adjacent the magnetically operable gas supply valve, the gas supply valve would open. When the magnetic key is removed, the gas supply valve would close. In other embodiments, a magnetic sensor may sense the presence or absence of a magnetic key. If the magnetic key is present, the magnetic sensor would generate an opening signal which causes the gas supply valve to open. When the magnetic key is removed, the magnetic sensor would generate a closing signal which causes the gas supply valve to close.

    Abstract: A gas cooking hob comprising a number of gas burners, each of which is connected to a main gas pipe via a gas pipe section, and a main switch. The main gas pipe or the gas pipe section is open to supply gas to the gas burners when the main switch is actuated while a gas supply to the gas burners is interrupted when the main switch is actuated once again. In order to be able to jointly interrupt gas supply to all gas burners even without the user acting directly upon the main switch, a timing member is assigned to the main switch in order to adjust an interval after which the main switch closes automatically.

  • Patent number: 7967005
    Abstract: A duel fuel gas control valve controls the supply of gas (e.g., natural gas or liquid propane gas) to a gas grill. The duel fuel gas control valve is structured to control either natural or LP gas flow at the desired operating characteristics based on conventional gas supply characteristics and gas grill requirements. A restrictor mechanism, when in first and second configurations, respectively, restricts movement of the valve core to a first predetermined range for a first mode of operation (first type of gas supply) and to a second predetermined range for a second mode of operation (second type of gas supply).
