And, the control device is additionally operable to obtain the duration T1 that current flow through hot water line 40, cold water pipeline 50, according to the T1 again
The T is configured, the T is more than or equal to the T1/2.
In the present embodiment, hot water line 40, cold can be flowed through by judging that flow rate of water flow, hydraulic pressure, temperature etc. obtain current
The duration T1 of water lines 50.It should be noted that for different users, room layout and area all may be different, this
If judging according to the pre-set time, then when hot water route is shorter, hot water heating is excessive, causes hot water to follow for sample
Repeat-heating after ring, wastes the energy；And when hot water route is more long, then not necessarily can guarantee that hot water reaches hot water line 40 most
Distal end.In the present embodiment, the duration T1 of hot water line 40, cold water pipeline 50 is flowed through by obtaining current, it is possible to know hot water
The length of pipeline 40, then reasonable disposition T, it is possible to which guarantee just makes full of hot water in hot water line 40, and in cold water pipeline 50
Or during cold water, it is possible to use hot water, i.e., simply make full of hot water in hot water line 40, the heat time is short, so realizing
While zero cold water, moreover it is possible to ensure user to use hot water in the most fast time, without being to wait for heating tube road 20, hot water line
40th, after the cold water of cold water pipeline 50 and the remaining of inlet pipeline 30 is all heated, could for users to use, the efficiency of heating surface is greatly promoted.
Also, flow through hot water line 40 by obtaining current, the duration T1 of cold water pipeline 50 reconfigures preset duration T,
The distalmost end of hot water line 40 can be ensured to be sent to hot water, it is ensured that user's family can immediately use hot water everywhere.
Additionally, the present invention also provides a kind of control method of gas heater, the method can be based on above-mentioned gas heater
Structure realize, or structure based on same principle is realized, do not limit, the present embodiment for convenience of understanding, with above-mentioned
The implementation process of the inventive method, reference picture 1 and Fig. 2 are told about as a example by gas heater, the method includes：
When step S10, gas heater receive computer heating control and instruct, timing simultaneously starts water circulating pump 70 and works, to drive
Water circulation flowing in dynamic heating pipeline 20, hot water line 40, cold water pipeline 50 and inlet pipeline 30；
It is understood that when water circulating pump 70 works, because inlet pipeline 30 is not intake, then inlet pipeline can be driven
30th, the circulating chilled water flowing remained in heating pipeline 20, hot water line 40 and cold water pipeline 50, now, in heating pipeline 20
The hot water of heating flows to hot water line 40, and the cold water flow in hot water line 40 to cold water pipeline 50, i.e. water circulating pump 70 are taken out
Cold water in intake pipe is heated in pipeline 20 is heated, and the hot water that will be heated cruises in water pipe.
Step S20, when timing time reaches preset duration T, control water circulating pump 70 is stopped, and controls water inlet pipe
Road 30 intakes.
Duration T1 wherein preset duration T required when can be exhausted according to the cold water in hot water line 40 and cold water pipeline 50
It is configured, will be generally above T1/2, in this way, by rationally setting preset duration T, it is possible to ensures that user opens in opening hot water
Guan Shi, the cold water in hot water line 40 is drained only, and the hot water after heating is in hot water line 40, so as to it is most fast when
Between ensure that user can use hot water, realize zero cooled water discharge, it is not necessary to cold in hot water line 40 as emitting in the prior art
Upper hot water could be used after water, it is very convenient, timely.
Further, reference picture 3, the control method of the gas heater also includes：
Step S30, when gas heater is first powered on, the control heating pipelines 20, hot water line of inlet pipeline 30 pairs
40 and cold water pipeline 50 carry out water filling, and start water circulating pump 70 and work；
Step S40, acquisition current flow through the duration T1 of hot water line 40, cold water pipeline 50, are reconfigured according to the T1
The T, the T are more than or equal to the T1/2.
In the present embodiment, hot water line 40, cold can be flowed through by judging that flow rate of water flow, hydraulic pressure, temperature etc. obtain current
The duration T1 of water lines 50.It should be noted that for different users, room layout and area all may be different, this
If judging according to the pre-set time, then when hot water route is shorter, hot water heating is excessive for sample, causes to repeat to add
Heat, wastes the energy, when hot water route is more long, then not necessarily can guarantee that hot water reaches the distalmost end of hot water line 40, this implementation
Hot water line 40 is flowed through by obtaining current, the duration T1 of cold water pipeline 50 reconfigures preset duration T, it is ensured that will in example
Hot water is sent to the distalmost end of hot water line 40.
In the present embodiment, hot water line 40, cold can be flowed through by judging that flow rate of water flow, hydraulic pressure, temperature etc. obtain current
The duration T1 of water lines 50.It should be noted that for different users, room layout and area all may be different, this
If judging according to the pre-set time, then when hot water route is shorter, hot water heating is excessive, causes hot water to follow for sample
Repeat-heating after ring, wastes the energy；And when hot water route is more long, then not necessarily can guarantee that hot water reaches hot water line 40 most
Distal end.In the present embodiment, the duration T1 of hot water line 40, cold water pipeline 50 is flowed through by obtaining current, it is possible to know hot water
The length of pipeline 40, then reasonable disposition T, it is possible to which guarantee just makes full of hot water in hot water line 40, and in cold water pipeline 50
Or during cold water, it is possible to use hot water, i.e., simply make full of hot water in hot water line 40, the heat time is short, so realizing
While zero cold water, moreover it is possible to ensure user to use hot water in the most fast time, without being to wait for heating tube road 20, hot water line
40th, after the cold water of cold water pipeline 50 and the remaining of inlet pipeline 30 is all heated, could for users to use, the efficiency of heating surface is greatly promoted.
Also, flow through hot water line 40 by obtaining current, the duration T1 of cold water pipeline 50 reconfigures preset duration T,
