Kind Code:
A1
Abstract:
Disclosed are a gas water heater and a safety control system and method therefor. The system comprises: an air exhauster (10) used to exhaust waste gas produced during combustion by a gas water heater; a rotary speed detection unit (20) used to detect the rotary speed of the air exhauster (10); a power acquisition unit (30) used to acquire an output power given value of the air exhauster (10); and an air-exhausting control unit (40) respectively connected to the air exhauster (10), the rotary speed detection unit (20) and the power acquisition unit (30), and used to determine an air pressure condition of an air outlet of the air exhauster (10) according to the rotary speed and the output power given value of the air exhauster (10) and to adjust the output power given value of the air exhauster (10) according to the air pressure condition of the air outlet of the air exhauster (10). The system can ensure that a gas water heater has a good combustion condition, guarantees the safe and reliable operation thereof and improves the control accuracy.
