Abstract
The present invention relates to a boiler having a gas sensing and an earthquake sensing function and a control method thereof, in which a gas leakage and an earthquake occurrence are automatically sensed and thus the boiler is forcibly stopped by causing fuel supply thereto to be cut off. The present invention is configured to cause fuel supply to the boiler to be cut off by comprehensively determining whether gas is leaking from the boiler and whether an earthquake has occurred at the present time, thereby minimizing loss of life due to the gas leakage and the earthquake occurrence.
Claims14
A boiler having a gas sensing and an earthquake sensing function, the boiler comprising:
- a boiler body receiving a fuel and generating flame;
- a gas sensor provided in the boiler body to sense gas and generate a gas sensing signal;
- an earthquake sensor provided in the boiler body to sense an earthquake and generate an earthquake sensing signal;
- a controller configured to
- generate, in response to a gas concentration determined based on the gas sensing signal generated by the gas sensor, or in response to an earthquake sensitivity determined based on the earthquake sensing signal generated by the earthquake sensor, a cut-off signal configured to cut off fuel supply to the boiler body,
- wherein the controller is further configured to
- receive, from a user, a sampling period,
- accumulate, for the sampling period, the gas concentration determined based on the gas sensing signal generated by the gas sensor,
- extract a lowest value and a highest value from among the accumulated gas concentrations,
- set an allowable gas concentration range based on the extracted lowest value and highest value, and
- determine, after the sampling period, whether to generate the cut-off signal based on the allowable gas concentration range.
