Description
Technical field
The utility model is related to field of sanitary ware, more particularly to a kind of reflux formula constant-temperature water discharge device.
Background technology
In weather cold, people wash one's face and rinse one's mouth, take a shower, doing washing, clean and be required for using hot water, with electricity, combustion gas and solar energy
Based on miscellaneous water heater early have been enter into huge numbers of families, but water heater is when in use, and hot water tends not to reach immediately
At water outlet, but need first by pipeline cold water empty, these cold water exclude after need dedicated container to store, waste time and
Space extremely influences the convenience used, if directly draining the significant wastage that can cause water resource.People when hot water is used,
In order to which quickly the cold water in pipeline is discharged, often hot water flow is opened to maximum, when hot water flows out, is further adjusted
Temperature is saved, can equally water resource be caused unnecessary waste by doing so, and common constant-temperature water mixing valve can be certain on the market at present
Lower water temperature is solved the problems, such as in degree, but the waste of cold water can not be avoided before hot water entrance.
Invention content
In view of the deficiencies of the prior art, the utility model provides a kind of reflux formula constant-temperature water discharge device.
The technical solution adopted in the utility model is：A kind of reflux formula constant-temperature water discharge device, including water heater, constant temperature water mixing
Valve and outlet pipeline, the constant temperature mix water valves and the first water inlet, the second inlet and outlet, first water inlet are arranged
The water heater is connected, second water inlet connects tap water pipe line, and the water outlet connects outlet pipeline, further includes cold water
Case and reversal valve, the reversal valve P mouthfuls of connection cold water storage cisterns are separately connected the second water inlet and water outlet with tap water pipe line, A, B mouthfuls
Mouthful, the tap water pipe line is provided with check valve, and the check valve is single in tap water pipe line to cold water storage cistern/second water inlet direction
To conducting.
A kind of reflux formula constant-temperature water discharge device, it is characterized in that：Temperature sensor is set in the constant-temperature water mixing valve,
The reversal valve is two position, three-way electromagnetic change valve, and the reversal valve is controlled by PLC controller, the PLC controller and institute
State temperature sensor connection.
Cold water in pipeline is first temporarily stored in cold water storage cistern by the utility model, after hot water outflow, then will be in cold water storage cistern
In cold water reflux back-mixing water valve, the automatic storage and reflux that reversal valve realizes cold water, the utility model are controlled by PLC controller
Without manual operation, you can effectively avoid water resource waste.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
In figure：1- water heaters, 2- cold water storage cisterns, 3- outlet pipelines, 4- constant-temperature water mixing valves, 5- reversal valves, 6- check valves, 7- temperature
Spend sensor, the first water inlets of 8-, the second water inlets of 9-, 10- water outlets, 11-PLC controllers.
Specific implementation mode
As shown in Figure 1, water heater 1 connects the first water inlet 8 of constant-temperature water mixing valve 4, the second water inlet of constant-temperature water mixing valve 4
The A mouths of 9 connection reversal valves 5, the water outlet 10 of constant-temperature water mixing valve 4 connect the B mouths of outlet pipeline 3 and reversal valve 5, the P of reversal valve 5
Mouth connection cold water storage cistern 2 and tap water pipe line, reversal valve 5 are two position, three-way electromagnetic change valve, and electromagnet is controlled by PLC controller 11
System, PLC controller 11 are connect with the temperature sensor 7 in constant-temperature water mixing valve 4, and temperature sensor 7 provides perseverance to PLC controller 11
Real time temperature data in warm water mixing valve, tap water pipe line are provided with check valve 6, and check valve 6 is in tap water pipe line to cold water storage cistern/the
Two water inlet direction one-way conductions.
In use, setting PLC controller trigger temperature, open constant-temperature water mixing valve, at this point, in constant-temperature water mixing valve temperature compared with
It is low, temperature is not up to triggered, the B mouths of reversal valve 5 are connected to P mouthfuls, and cold water passes through reversal valve by water outlet 10 in constant-temperature water mixing valve 4
5 flow into cold water storage cistern 2；After hot water flows into constant-temperature water mixing valve 4 in water heater, water temperature gradually rises to triggering temperature, temperature
Sensor 7 triggers PLC controller 11 and sends out signal so that 5 electromagnet of reversal valve is obtained electric, at this point, the A mouths of reversal valve 5 are connected to P mouthfuls,
When the water of outlet pipeline 3, the cold water in cold water storage cistern 2 is flowed by reversal valve 5 in constant-temperature water mixing valve 4, mixed to reach suitable
The hot water of temperature is conveyed by water outlet 10 to outlet pipeline, and when flow passes in and out in cold water storage cistern, check valve 6 can guarantee flow not
It can reverse direction flow tap water pipe line.
