Cold water flow.
In addition, being provided with the first water pump 45 close to domestic water outflow port on heat exchanger 3 on domestic water line 4, use
In recycling the water in domestic water line 4.
As shown in Fig. 2, the dual-purpose stove working method in the present embodiment, comprising the following steps:
S1, user open quick heating work mode as needed；When just having opened heating, the temperature in room is low, even if
The leaving water temperature of heating water circulation pipeline 2 is higher, but make the bulk temperature in room rise to a stable temperature need compared with
The long time needs to continue to keep the state, so that the bulk temperature in room constantly rises；In order to guarantee that heating process will not be because
Leaving water temperature for heating water circulation pipeline 2 is higher and interrupts, and achievees the purpose that quick heating, the dual-purpose stove in the present embodiment
There is quick heating work mode, user is turned on or off the quick heating work mode as needed；
Whether S2, judgement are current in quick heating work mode；
If it is not, then dual-purpose stove is in common operating mode, under normal mode of operation, during heating, if inspection
The flow signal of domestic water is measured, then triple valve 5 is connected to heat exchanger 3, and then 2 water exit end of heating water circulation pipeline flows out
Heated heating water then flow into heat exchanger 3, domestic water exchanges heat with the heating water in heat exchanger 3, and then right
Domestic water is heated, so that the water that domestic water line 4 flows out reaches set temperature, during being somebody's turn to do, if the first temperature
Sensor 41 is detected to be higher than on domestic water line 4 close to the leaving water temperature on heat exchanger 3 at domestic water outflow port and be set
Determine temperature, then control and open water adjusting valve 71, and then be mixed into the cold water inputted in domestic water line 4, reduces water temperature, so that
The leaving water temperature of 4 water outlet of domestic water line reaches set temperature；
Under normal mode of operation, it is determined whether to enable zero cold water functions；If opening zero cold water function, starting is controlled
First water pump 45, and then the water in domestic water line 4 is driven to circulate, it is preheated by the heat exchange effect of heat exchanger 3.
During being somebody's turn to do, if necessary to domestic water, when just opening, since domestic water line 4 is preheated, avoid occur early period cold
The case where water.5 switched conductive connecting pipe of triple valve simultaneously, so that through combustion heat-exchange device 1 in heating water circulation pipeline 2
Water after heating flows into heat exchanger 3, exchanges heat with the water in domestic water line 4, and then in domestic water line 4
Water heated, the leaving water temperature in domestic water line 4 meets the needs of user.In the use process of domestic water, the
41 moment of one temperature sensor monitors on domestic water line 4 close to the water temperature out on heat exchanger 3 at domestic water outflow port
Degree, 42 sensor moment of second temperature sensor monitor the leaving water temperature of 4 water outlet of domestic water line, third temperature moment
The inflow temperature for monitoring domestic water line 4, so can be effectively controlled leaving water temperature and reaches sets requirement, if water service pipe
It is higher than set temperature close to the leaving water temperature on heat exchanger 3 at domestic water outflow port on road 4, then controls unlatching water adjusting valve
71, and then it is mixed into the cold water inputted in domestic water line 4, water temperature is reduced, so that 4 water outlet of domestic water line
Leaving water temperature reaches set temperature；
If it is dual-purpose stove carries out quick heating work mode, i.e. progress S3,；
S3, judge whether active user has demand of domestic water；If it is, carrying out S4；If otherwise carrying out S5；
S4, heating work state is kept；
Judge whether user's domestic water flow reaches the minimum for meeting quick heating work mode lower water-back cooling demand
Water, if it is not, then opening drain valve 61 and adjusting the aperture of drain valve 61, so that user's domestic water flow and drainage pipeline
The sum of water flow in 6 is greater than the least quantity of quick heating work mode lower water-back cooling demand；
For in the case where needing domestic water, the water in domestic water line 4 to carry out heat exchange with heating water
In the process, the leaving water temperature of domestic water line 4 could possibly be higher than set temperature, then needs to detect simultaneously to live on heat exchanger 3 and use
Whether the leaving water temperature of water flow exit port is higher than set temperature；If not, due in quick heating work mode process, life
It is being flowed always with the water in waterpipe 4, i.e., is carrying out heat exchange with heating water in heat exchanger 3 always, be then not in water outlet
The case where for cold water, i.e., the function of zero cold water is realized automatically；If it is, control opens water adjusting valve 71 and adjusts water adjusting valve 71
Aperture；The leaving water temperature for adjusting domestic water line 4 reaches set temperature.
S5, control open drain valve 61, and the water in domestic water line 4 is discharged directly to discharge outlet from drainage pipeline 6
Or do other water conservancies in family and use, it can guarantee that the water in domestic water line 4 is flowing always, water service pipe
Water inlet in road 4 carries out heat exchange with heating water in heat exchanger 3, the return water temperature of heating water is reduced, when guaranteeing dual-purpose furnace superintendent
Between lasting carry out heating work, it is excessively high and interrupt heating work to avoid the occurrence of heating leaving water temperature, improves the heating of heating
Rate.
Heat exchanger 3, is connected in series in the return water of heating water circulation pipeline 2 by the dual-purpose stove work system in the utility model
Duan Shang can follow heating water by the water flow in domestic water line 4 using the dual-purpose stove working method in the utility model
Heating return water in endless tube road 2 cools down, and avoids when the space temperature for needing heating does not rise, due to heating water circulation pipe
Water temperature over-high in road 2 and cause to stop heating.The duration of the heating work state of so certifiable dual-purpose stove, so that dual-purpose
Furnace is maintained at the longevity of service of heating work state, achievees the purpose that the quick heating in space.Simultaneously because during heating,
Heat exchanger is in running order, and the water in domestic water line 4 is able to carry out effective heat exchange, is there is demand of domestic water
When, the effect of zero cold water is realized, the function of zero cold water will not interrupt heating work, can carry out simultaneously with heating.
