Valve arrangement for a gas burner
According to one embodiment a valve arrangement for a gas burner is provided that includes a manual gas valve with a manual actuator for opening or closing the gas flow, and an electromagnetic valve having a movable closure member which allows opening or closing a gas passage to the burner. The electromagnetic valve is arranged in the gas valve, with the manual actuator being coupled to a rotary flow regulating element, the manual actuator being configured in order to move the closure member of the electromagnetic valve, opening the gas passage, the manual gas valve including a reduced gas flow channel which puts the inlet conduit in fluid communication with the regulating element regardless of the position of the closure member.
THERMOELECTRIC SAFETY ASSEMBLY
A thermoelectric safety assembly that includes a thermocouple configured to detect a flame in a burner and, in response to detecting the flame, generating an electrical voltage. The assembly includes an electromagnetic valve electrically connected to the thermocouple, and a transistor electrically connected between the thermocouple and the electromagnetic valve. The electromagnetic valve is arranged electrically connected with a field-effect transistor. The assembly also includes a voltage booster configured to power the transistor, the transistor being connected in parallel with the voltage booster. An output terminal of the voltage booster is arranged connected with a gate terminal of the transistor, the voltage booster being configured to boost the electrical voltage generated in the thermocouple, an electrical voltage being obtained that is capable of keeping the transistor closed such that the electromagnetic valve is energized.
Gas control valve featuring magnetic control and gas ignition system having the same
A gas control valve featuring magnetic control and a gas ignition system having the same are disclosed. The gas control valve includes a main body and a magnetic control assembly. The main body has a valve base and a control lever. The control lever is movably connected to the valve base. The magnetic control assembly has a magnetic member and a magnetic control switch. The magnetic member is installed in one of the valve base and the control lever, while the magnetic control switch is installed in the other of the valve base and the control lever. When the control lever moves to an ignition position, the magnetic control switch is affected by the magnetic member and forms a closed circuit. The magnetic control assembly is incorporated in the gas control valve in a modularized manner, and can be easily maintained and repaired.
THERMOELECTRIC ASSEMBLY FOR POWERING ELECTROMAGNETIC VALVES OF A COOKING APPLIANCE
A thermoelectric assembly for powering one or more electromagnetic valves of a cooking appliance. According to one embodiment the assembly includes a main current circuit that includes a thermocouple, a cable configured for electrically connecting the thermocouple with an electromagnetic valve, and a transistor connected to the cable and configured for de-energizing the electromagnetic valve. The main current circuit also includes a connection module that includes a power supply connected to the transistor, the power supply having input terminals configured for being connected to an external energy source, a rectifier, and a resistive block connected between one of the input terminals and the rectifier, the resistive block being configured for minimizing the current circulating through the power supply to a value equivalent to the galvanic isolation.
