Abstract

The invention discloses a gas water heater and a safety control system and method thereof. The system comprises an exhaust fan for exhausting waste gas produced by the gas water heater during burning,a rotary speed detecting unit for detecting the rotary speed of the exhaust fan, a power obtaining unit for obtaining an output power given value of the exhaust fan, and an exhausting control unit connected with the exhaust fan, the rotary speed detecting unit and the power obtaining unit and used for judging the air outlet air pressure situation of the exhaust fan according to the rotary speed of the exhaust fan and the output power given value of the exhaust fan and regulating the output power given value of the exhaust fan according to the air outlet air pressure situation of the exhaust fan. The system can ensure that the gas water heater has good burning conditions and ensure safe and reliable operation of the gas water heater, is high in response speed and lower in cost, can providemore accurate air volume and improves the control accuracy.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a gas water heater and its safety control system and method. Background technique [0002] At present, the common gas water heaters on the market include: D type (natural exhaust), Q type (forced exhaust), P type (natural supply and exhaust), G type (forced supply and exhaust) and W type (outdoor setup), etc. Among them, the Q-type and G-type gas water heaters are directly equipped with an exhaust fan to forcefully discharge the waste gas during combustion to prevent the residual gas from burning and exploding. [0003] In related technologies, Q-type gas water heaters usually use a wind pressure detection unit to detect the wind pressure at the outlet, and then control the exhaust fan and ignition unit according to the detected wind pressure to ensure that the gas water heater can work normally. Although adopting the wind pressure detection unit can avoid the combustion ...
