Abstract

The invention discloses a gas water heater. The gas water heater comprises a combustor, a gas pipe, a flue gas discharging pipe, a fan assembly and an air pressure protection control circuit, wherein the air pressure protection control circuit comprises a control mainboard, an air pressure detection unit and a gas proportional valve arranged on the gas pipe, the control mainboard is electrically connected with the air pressure detection unit, the gas proportional valve and the fan assembly, and the air pressure detection unit is used for detecting the pressure of air in the flue gas discharging pipe. Due to the facts that measured air pressure values are converted into voltage signals which are continuously output, and the voltage signals are transmitted to the control mainboard, control over the gas proportional valve, a water proportional valve and the fan assembly can be achieved, the working state of the gas water heater is adjusted according to the current air pressure value, the gas water heater can adapt to changes of the environment, combustion performance of the gas water heater is ensured, the using performance of the gas water heater is improved, and the requirements for safety, environmental friendliness and practicability are met. The invention further discloses a gas water heater. The gas water heater adapts to changes of the environment through control over the flue gas discharging power of the fan assembly.

Description

technical field [0001] The invention relates to the technical field of gas appliances, in particular to a forced exhaust gas water heater with a wind pressure protection device. Background technique [0002] With the popularization and application of gas water heaters, it has brought great convenience to people's daily life. At the same time, safety accidents caused by insufficient combustion of gas or gas leakage have occurred frequently. Therefore, the country stipulates in the standards of gas water heaters that, It must be equipped with a strong exhaust fan. When the gas water heater is started, the strong exhaust fan simultaneously exhausts the waste gas generated by combustion. However, when using a gas water heater, if the external wind pressure is too high, the smoke exhaust resistance of the gas water heater will increase during use, and the smoke exhaust efficiency of the strong exhaust fan will become lower, resulting in insufficient combustion, excessive exhaust ...
