Open at least any one watering equipment, the water pump of gas heater is opened, tap water by inlet pipeline to
Wetting system supplies water, and the hot water after gas heater heats is supplied water by outlet pipeline to watering equipment；Acquisition flows through back in real time
The water temperature of water lines, i.e. inflow temperature T1, and according to the inflow temperature T1With the determining water of comparison of the first temperature threshold
Whether equipment closes；After determination has been switched off to watering equipment, the water pump of gas heater is closed, according to water in outlet pipeline
The case where flow, determines whether to close gas heater.
The features of the present invention also characterized in that:
First temperature threshold is T0+ N, wherein T0For minimum inflow temperature, N > 5.
First temperature threshold is (T0+ Ts)/2, wherein T0For minimum inflow temperature, Ts is that temperature is arranged in water heater.
The minimum inflow temperature T0It is obtained after water heater water pump starting by the water temperature that acquisition flows through inlet pipeline；When
The water temperature of acquisition is less than minimum inflow temperature T0When, using the water temperature as minimum inflow temperature T0。
The inflow temperature T that the basis acquires in real time1Determine watering equipment with the comparison of the first temperature threshold
It closes, specifically: as the inflow temperature T of the acquisition1When greater than the first temperature threshold, determine that watering equipment has been switched off.
This method further include: as the inflow temperature T of the acquisition1When less than or equal to the first temperature threshold, determination is set with water
It is standby to be used, the open state of water pump is maintained, gas heater works on.
It is described according to determine whether the case where water flow in outlet pipeline close water heater, specifically: when the water flow
When less than flow threshold, gas heater is closed；When the water flow is more than or equal to flow threshold, gas heater continues work
Make.
It is described when the water flow be more than or equal to flow threshold when, gas heater works on, and later, also wraps
It includes: as the inflow temperature T acquired in real time1When less than second temperature threshold value, water pump is reopened.
The second temperature threshold value is T0+ M, wherein T0For minimum inflow temperature, M > 3.
The second temperature threshold value is (T0+ Ts)/2-2, wherein T0For minimum inflow temperature, Ts is gas heater setting
Temperature.
Compared with prior art, the present invention passes through the inflow temperature T acquired in real time1With the comparison of the first temperature threshold
It after determining that user has been switched off watering equipment, switches off the pump, is determined whether to close water heater according to the case where water flow, it is dual to sentence
It has no progeny and controls gas heater and intelligently shut down, prevent from judging by accident.
