Gas burner for a household appliance

A thermoelectric safety actuator comprising:

• a first body having a first cavity and a second body having a second cavity, the first and second bodies being connected so that a gas-tight seal exists between a first contact surface of the first body a second contact surface of the second body and so that the first and second cavities are arranged facing and open to one another, the first body having a gas outlet, the second body having a gas inlet in fluid communication with the gas outlet through the second cavity,
• an electromagnet comprising a first end portion with a first end and a second end portion with a second end, the first end portion residing in the first cavity of the first body and the second end portion residing in the second cavity of the second body,
• a tilting arm rotatable between a rest position when the electromagnet is de-energized and an activation position when the electromagnet is energized, the tilting arm comprising a moving part with a first end having a ferromagnetic frame and a second end coupled to a first sealing member, each of the tilting arm, ferromagnetic frame and first sealing member arranged in the second cavity of the second body, the first sealing member adapted to seat against a first seating located on the first body when the tilting arm is in the rest position, the first seating being located between the gas outlet and the second cavity, in the rest position the ferromagnetic frame of the tilting arm is located a distance apart from the second end of the electromagnet, in the activation position the ferromagnetic frame of the tilting arm being located against the second end of the electromagnet with the first sealing member being located apart from the first seating on the first body.

A gas burner assembly for a gas appliance comprising:

• a burner casing,
• an injector situated in the burner casing configured to introduce a gas into the burner, the injector having a gas inlet and a gas outlet,
• a thermoelectric safety actuator arranged fixed to the casing and comprising:
• a first body having a first cavity and a second body having a second cavity, the first and second bodies being connected so that a gas-tight seal exists between a first contact surface of the first body a second contact surface of the second body and so that the first and second cavities are arranged facing and open to one another, the first body having a gas outlet, the second body having a gas inlet in fluid communication with the gas outlet through the second cavity, the gas outlet being connected to the gas inlet of the injector via a gas-tight connection,
• an electromagnet comprising a first end portion with a first end and a second end portion with a second end, the first end portion residing in the first cavity of the first body and the second end portion residing in the second cavity of the second body,
• a tilting arm rotatable between a rest position when the electromagnet is de-energized and an activation position when the electromagnet is energized, the tilting arm comprising a moving part with a first end having a ferromagnetic frame and a second end coupled to a first sealing member, each of the tilting arm, ferromagnetic frame and first sealing member arranged in the second cavity of the second body, the first sealing member adapted to seat against a first seating located on the first body when the tilting arm is in the rest position, the first seating being located between the gas outlet and the second cavity, in the rest position the ferromagnetic frame of the tilting arm is located a distance apart from the second end of the electromagnet, in the activation position the ferromagnetic frame of the tilting arm being located against the second end of the electromagnet with the first sealing member being located apart from the first seating on the first body.
