Abstract

The invention belongs to the technical field of gas water heaters, and discloses a control method of a gas water heater and a gas water heater. The control method of the gas water heater includes the following control steps: detecting the water flow signal and judging whether it is greater than the safe flow value; if it is greater than the safe flow value, further judging whether the duration of the water flow signal is greater than the interference set value; If the interference set value is set, control the gas water heater to start heating; judge whether the water flow signal is greater than the maximum flow value, if greater than the maximum flow value, then judge whether the duration of the water flow signal is greater than the record replacement value, if greater If the record replacement value is changed, then the safe flow value is re-determined according to the water flow signal. The gas water heater is controlled using the above-mentioned control method of the gas water heater. The invention can eliminate instantaneous interference water flow signals such as toilet flushing without prolonging the detection time of water flow.

Description

Technical field [0001] The present invention relates to gas water heater technology, and more particularly relates to a control method for a gas water heater and gas heater. Background technique [0002] Also known as gas water heater gas water heater, it refers to the gas as fuel, heating by combustion, to transfer heat to the cold water through the heat exchanger in order to achieve a gas appliance hot water preparation purposes. Conventional gas water heater is usually started by the detection signal of the water flow, when the user opens water valve flow sensor on the gas water heater will detect the water flow signal, this signal is output to the heater panel, panel heaters started fan, ignition discharge ignition, gas valve is opened, supply of hot water heater starts to burn. [0003] In actual use, because of structural problems in the home water conduit, after flushing the toilet flushing is completed, a signal is generated a reverse impact of water in the pipeline, the ...
