Abstract
The invention refers to a method for detecting anomalies associated with a gas appliance (1), the gas appliance (1) comprising at least a gas inlet (2), at least one gas burner (3) and gas distribution means (4) coupling the gas inlet (2) with said at least one gas burner (3), the method comprising the steps of:—gathering information regarding the gas flow or the operational state based on detection means (5.1, 5.2) (S20);—evaluating said gathered information in order to detect gas flow anomalies or operational anomalies, thereby obtaining evaluation information (S21);—providing alert information from a communication interface of the gas appliance (1) to a user device (6) depending on said evaluation information (S22).
Claims20
Method for detecting anomalies associated with a gas appliance, the gas appliance comprising at least a gas inlet, at least one gas burner and gas distribution means coupling the gas inlet with said at least one gas burner, the method comprising the steps of:
- gathering information regarding gas flow or an operational state based on detection means;
- evaluating said gathered information in order to detect gas flow anomalies or operational anomalies, thereby obtaining evaluation information;
- providing alert information from a communication interface of the gas appliance to a user device depending on said evaluation information.
A domestic gas appliance, the gas appliance comprising at least a gas inlet, at least one gas burner and gas distribution means coupling the gas inlet with said at least one gas burner, the gas appliance further comprising:
- detection means for gathering information regarding a gas flow or an operational state of the gas appliance;
- evaluation means coupled with said detection means, said evaluation means being adapted to gather information in order to detect gas flow anomalies or operational anomalies and adapted to provide evaluation information;
- a communication interface adapted to provide alert information to a user device based on said evaluation information.
A method for detecting anomalies in a gas appliance, comprising:
- a) a first sensor of the appliance communicating to a controller of the appliance a first sensor signal indicative of a gas flow rate through the appliance;
- b) a second sensor of the appliance communicating to said control a second sensor signal indicative of an ignition state of a gas burner of the appliance;
- c) said controller evaluating said first and second sensor signals and thereby determining there to be present:
- a. a gas leak, if both the first sensor signal indicates positive gas flow through said appliance and the second sensor signal indicates said burner is not ignited;
- and
- b. extended operation of the gas burner, if for a predetermined period of time both the first sensor signal indicates positive gas flow through said appliance and the second sensor signal indicates said burner is ignited;
- and
- d) said appliance communicating alert information via a communication interface to a user device to indicate that a gas leak is present in the appliance and/or that said burner has been operating for an extended period of time, as the case may be, as determined by said controller based on evaluating said first and second sensor signals.
