Abstract
A fire protection device for preventing damage to a domestic appliance from a malfunction which occurs in the appliance. The fire protection device includes at least one fault current circuit breaker, which disconnects the electrical supply from the appliance when a fault current is sensed. The fire protection device also includes at least one gas sensor which also disconnects the electrical supply from the appliance when a predetermined quantity of a control gas is sensed in the appliance.
Claims18
A fire protection device for a domestic appliance, the fire protection device comprising:
- a fault current detector to detect a fault current in the domestic appliance and to generate a fault current signal upon detection of the fault current;
- a fault current switch arranged inside the domestic appliance, the fault current switch to receive the fault current signal from the fault current detector and to disconnect power supply to the domestic appliance from the domestic appliance;
- a gas sensor to detect a threshold quantity of a control gas in the domestic appliance and to generate a control gas threshold signal upon detection of the threshold quantity of the control gas;
- and
- a main switch to receive the control gas threshold signal from the gas sensor and to disconnect the power supply to the domestic appliance from the domestic appliance.
