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 fuel cut-off unit receiving a cut-off signal to cause fuel supply to the boiler body to be cut off;
- and
- 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 gas concentration determiner receiving the gas sensing signal from the gas sensor to determine a gas concentration;
- an earth sensitivity determiner receiving the earthquake sensing signal from the earthquake sensor to determine an earthquake sensitivity;
- and
- a controller transmitting the cut-off signal to the fuel cut-off unit according to the gas concentration determined by the gas concentration determiner, or transmitting the cut-off signal to the fuel cut-off unit according to the earthquake sensitivity determined by the earthquake sensitivity determiner.
A method of controlling a boiler having a gas sensing and an earthquake sensing function, the method comprising:
- a gas concentration determination step receiving a gas sensing signal from a gas sensor provided in a boiler body and determining a gas concentration, by a gas concentration determiner;
- a first comparison step comparing whether or not the gas concentration transmitted from the gas concentration determiner is out of a predetermined allowable gas concentration range, by a controller;
- a first cut-off step transmitting, by the controller, a cut-off signal to a fuel cut-off unit to cause fuel supply to the boiler body to be cut off when the gas concentration transmitted from the gas concentration determiner is out of the predetermined allowable gas concentration range;
- an earthquake sensitivity determination step receiving an earthquake sensing signal from an earthquake sensor provided in the boiler body and determining an earthquake sensitivity, by an earthquake sensitivity determiner;
- a second comparison step comparing, by the controller, whether or not the earthquake sensitivity transmitted from the earthquake sensitivity determiner is out of a predetermined allowable earthquake sensitivity range;
- and
- a second cut-off step transmitting, by the controller, the cut-off signal to the fuel cut-off unit to cause fuel supply to the boiler body to be cut off when the earthquake sensitivity transmitted from the earthquake sensitivity determiner is out of the predetermined allowable earthquake sensitivity range.
