Water body in hot-water line 112 flow to cold water pipe 111.To on the one hand, avoid output water flow deficiency, another party
Face also avoids heating part water body repeatedly.
S700: to 100 self-test of water heater, and judge whether water heater 100 is normal.
Wherein, in the present embodiment, after the enabling signal for receiving flow sensor 120, control piece 140 detects water respectively
Pump 160, the working condition of check valve 170, heating member 150 and flow sensor 120, with determine during the work time water pump 160,
Check valve 170, heating member 150 and flow sensor 120 being capable of works fines.
S800: in the state that water heater 100 is normal, the state equal with preset flow signal in water flow signal is executed
Under, control piece 140 controls the step of heating member 150 heats heating tube 113.
It should be noted that in the present embodiment, preset flow signal is in pipeline 110 from flow sensor 120 to adding
The volume of 113 this section of heat pipe, is heated repeatedly to avoid to part water body, causes local water temperature excessively high or right
Part water body is not heated, and causes part water temperature too low.Water temperature equalization to guarantee output is pleasant.
S900: under 100 abnormal state of affairs of water heater, fault-signal is issued.
It should be noted that in the present embodiment, issuing fault-signal in time by control piece 140 to remind user
Water heater 100 is checked, to avoid breaking down in use, protects the safety of user.
In conclusion 100 control method of water heater of offer of the invention stop supply water after, will be cold by water pump 160
Water pipe 111, heating tube 113 and water mixing in hot-water line 112 and the residual temperature for absorbing heating member 150, make cold water pipe 111 plus
When the temperature of water is uniformly again turned in heat pipe 113 and hot-water line 112, is collected by flow sensor 120 and pass through cold water pipe 111
Water flow signal control heating member 150 to heating tube and in the state that water flow signal is equal with preset flow signal
113 heating.To avoid carrying out Repeat-heating to the water body in pipeline 110 by evenly mixing, to guarantee the water body temperature of output
Degree is balanced pleasant.
The water heater 100 of offer of the invention passes through the water flow signal in 120 collecting 110 of flow sensor, and
Water flow signal is sent to control piece 140, in the state that water flow signal is equal with preset flow signal, passes through control piece
140 control heating members 150 heat heating tube 113.To avoid carrying out Repeat-heating to the water body in pipe by evenly mixing,
Water temperature equilibrium to guarantee output is pleasant.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
