Embodiment
Referring to Fig.1,4, water heater cold water recovery system, institute is described in detail for hot water terminal by one in the present embodiment
It includes water heater 1 to state water heater cold water recovery system, the hot water pipeline 2 being connected to water heater 1, at the same with hot water pipeline 2 and into
The first water mixing valve 4 that cold water pipes 3 are connected to.The present embodiment further makes following improvement：Further include cold water recovery channel 5,
One solenoid valve 6, second solenoid valve 7, the first check valve 8, controller 9 and water pump 10, first solenoid valve 6 connect cold water recycling
Pipeline 5, the first water inlet pipe 31 and the second water inlet pipe 32 into cold water pipes 3, the second solenoid valve 7 connect hot water pipeline 2, into
The second water inlet pipe 32 and the first water mixing valve 4 of cold water pipes 3, the hot water pipeline 2 and the second water inlet pipe 32 into cold water pipes 3
Between connect the first check valve 8, when opening hot water, the cold water that is flowed out from hot water pipeline 2 passes through successively into cold water pipes 3 and cold
Water recovery channel 5 is recycled in water heater 1, and the cold water recovery channel 5 is equipped with controller 9 and water pump 10, the control
Device 9 is that cold water recycling carries for driving the first solenoid valve 6, second solenoid valve 7, the first check valve 8, water pump 10, the water pump 10
For power.The first solenoid valve 6 described in the present embodiment, second solenoid valve 7 are three-way magnetic valve.
There are two operating mode, patterns one for the water heater cold water recovery system tool：When needing hot water, opening controller 9,
Controller 9 drives the first solenoid valve 6, second solenoid valve 7 to close, with reference to Fig. 2 it is found that closing the first solenoid valve 6, second solenoid valve
7 prevent the water of hot water pipeline 2 from flowing into the first water mixing valve 4, while the cold water into cold water pipes 3 also being prevented to enter water heater 1, control
Device 9 drives the first check valve 8 to open and water pump 10 is driven to work, and the water cycle in cold water recovery passage is got up, by Fig. 1 arrows
Shown direction carries out circulation and stress.After pattern two, cold water are recovered the regular hour, controller 9 can drive the first solenoid valve 6,
Second solenoid valve 7 is opened, and with reference to Fig. 3, after the first solenoid valve 6, second solenoid valve 7 power on, water (flow) direction can change, and first is single
It is closed to valve 8, water pump 10 is shut down, at this point, can both enter water heater 1 into the cold water in cold water pipes 3, can also pass through the first mixed water
The hot water of valve 4, hot water pipeline 2 can be directly entered the first water mixing valve 4.It the hot water pipeline 2 and is pressed into the water in cold water pipes 3
Arrow shown in Fig. 4 recycles.
After the water heater cold water recovery system starts, the run time user of pattern one can voluntarily set on controller 9
It is fixed.The principle of setting is, by the hot water in 4 heat release hydrophone 1 of the first water mixing valve, by how long the temperature of water be user can
With the temperature of receiving, then this time is the run time of pattern one, for example two minutes hot water is flowed out from hot water pipeline 2
User can receive, then set the run time of pattern one as two minutes.
User will not use always hot water, centre to have interruption, and user needs that maximum break period, the time is arranged at this time
Length voluntarily set on controller 9 according to usually use habit by user, the time determines that principle is, in going out after hot water
The disconnected hot water how long flowed out makes user feel that water has turned cold, for example, user stops using hot water, hot water pipeline 2 flows in ten minutes
The temperature user of the water gone out can receive, and the water temperature user other than ten minutes cannot receive, then the break period may be configured as ten
Minute.
As a preferred embodiment of the present embodiment, temperature sensor 11 is additionally provided on the cold water recovery channel 5.
The temperature sensor 11 can acquire the temperature of the cold water of recycling in real time, when the stopping cold water that temperature reaches the setting of controller 9 returns
When the temperature of receipts, cold water recovery system works into the pattern two.
As a preferred embodiment of the present embodiment, water flow switch 12 is additionally provided on the cold water recovery channel 5.When
After user stops using hot water, the water flow switch 12 can give controller 9 one low level signals, when user reuses hot water
Afterwards, water flow switch 12 can give microcontroller one high level signal at this time, if during low level signal is less than to the high level signal time
When the disconnected time, two operating mode of cold water recovery system Dietary behavior, if low level signal was more than or equal to the high level signal time
When the break period, cold water recovery system can first be operated in after pattern one pattern two that is transferred to again.
Embodiment two
With reference to Fig. 5,6, water heater cold water recovery system is described in detail for hot water terminal by two in the present embodiment, this
Embodiment and embodiment one difference lies in：On the basis of the cold water recovery system of embodiment one, increase by a second mixed water
Valve 13 increases by second check valve 14, increases third solenoid valve 15 and the 4th solenoid valve 16, and hot water pipeline 2 increases branch 21,
Increase third water inlet pipe 33 and the 4th water inlet pipe 34 into cold water pipes 3, it is described into the second water inlet pipe 32 of cold water pipes 3, third
Water inlet pipe 33 is connected to the 4th water inlet pipe 34 by third solenoid valve 15, the branch 21, the 4th water inlet pipe 34, the second water mixing valve
13 are connected to by the 4th solenoid valve 16, are also connected to by the second check valve 14 between the branch 21 and the 4th water inlet pipe 34.This
The third solenoid valve 15 and the 4th solenoid valve 16 of embodiment are also three-way magnetic valve.
The cold water recovery system of the present embodiment is also repeated no more there are two operating mode as embodiment one.Work as pattern
When one operation, controller 9 controls the first solenoid valve 6, second solenoid valve 7, third solenoid valve 15, the 4th solenoid valve 16 and closes, and beats
The first check valve 8, the second check valve 14 and water pump 10 are opened, the water in hot water pipeline 2 is by the cycle of direction shown in Fig. 5 arrows.When
When pattern two is run, controller 9 controls the first solenoid valve 6, second solenoid valve 7, third solenoid valve 15, the 4th solenoid valve 16 and beats
It opens, closes the first check valve 8, the second check valve 14 and water pump 10, water in hot water pipeline 2 and into cold water pipes 3
Water is by the cycle of direction shown in Fig. 6 arrows.
According to the present embodiment as can be seen that often increasing by one with hot water terminal, it is required for increasing by one on corresponding pipeline
A check valve and two solenoid valves.
