Description of reference numerals：1st, water heater 2, water inlet pipe 3, hot-water outlet pipe 4, followed with water spot 5, cold water pipe 6, hot water
Loop device 7, hot water branch road 8, temperature sensor 9, return pipe 10, check valve 11, temperature-sensing valve.
Embodiment
The technical program is explained in detail below in conjunction with specific embodiment.
As Figure 1-Figure 2, the utility model is a kind of hot water cyclesystem, including water heater 1, is connected with water heater
Water inlet pipe 2, hot-water outlet pipe 3, several with water spot 4 and for water spot supply cold water cold water pipe 5, installed in water feeding of heater end
Hot water circulating device 6, if hot-water outlet pipe is connected with main line and with the corresponding hot water branch road 7 of water spot, hot water circulating device includes
Master controller, operation display, water flow sensor and water circulating pump, water flow sensor and operate display respectively with master control
Device connection processed, master controller connection control water circulating pump；The output end of hot water of water heater is provided with temperature sensor 8, the temperature
The signal input part for spending sensor and master controller is connected, and distalmost end is connected with back between the cold water pipe and hot water branch road of water spot
Along outlet pipe to the flow direction of cold water pipe on water pipe 9, return pipe, check valve 10 and temperature-sensing valve 11 are disposed with.Temperature control valve opening
Size is mechanically controlled type, is not connected with hot water circulating device by temperature-sensing element control.
The following is hot water circuit control method, it is the water inlet pipe end setting in water heater mainly by master controller, operation
The hot water circulating device that display, water flow sensor, water circulating pump are constituted, sets temperature to pass in the output end of hot water of water heater
Sensor monitors the water temperature T of output end of hot water in real timeA, and the backwater between the hot water branch road and cold water branch road of distalmost end water spot
Pipe sets check valve and temperature-sensing valve, after start, and water circulating pump start-up temperature T is set by master controllerS＜ TC, TCFor water heater
The hot water temperature of setting.System circulation process is as follows：
Work as TA＜ TSWhen, initial start-up is circulated, water pump is started working, while water flow sensor detection flows Q；
As water temperature is raised in hot-water outlet pipe, temperature-sensing valve abrupt temp T is reachedT, the mutation of temperature control valve opening, pipeline water-carrying capacity
Rapid reduction；
As Q ＜ QSWhen, water pump is stopped, and circulation terminates；
After heating terminates, T is worked as in pipeline natural heat dissipation, temperature reductionB＜ TTWhen, temperature-sensing valve resets；
Work as TA＜ TSCirculation is again started up, and system is according to above-mentioned steps repeated work；
TB：Temperature at temperature-sensing valve；
TC：The hot water temperature of storage-type electric water heater setting；
TS：EGR start-up temperature, is set by the user；
TT：Temperature control valve opening abrupt temp；
Q：Real-time traffic in pipeline；
QS：Circulation stops flow.
In view of pipeline, rate of heat dispation is inconsistent everywhere, if B points rate of heat dispation is less than A points, there is A point temperature and drops to startup
Under value, the phenomenon that B point temperature control valve openings not yet reset, now starting mode of pump, because temperature-sensing valve does not reset, flow Q is less than Qs, water
Stop immediately after pump startup, circulation terminates.Be not in this phenomenon if B points rate of heat dispation is more than A points.It is being again started up process
In, temperature-sensing valve limits hot water and flows to cold water pipe, realizes and opens i.e. cold with water spot.
Fig. 2 is the control flow chart of hot water circulating device, user's setting start-up temperature TS, temperature sensor constantly detects heat
Hydrophone goes out hot water end A point temperature, works as TA<TSWhen start the cycle over, hot water flows through temperature-sensing valve, and temperature control valve opening produces mutation, pipeline stream
Amount Q diminishes rapidly, works as Q<QSWhen, circulation terminates.When being again started up, only temperature-sensing valve reset cycle can be just normally carried out, so
Not yet cooling high-temperature water in pipeline is prevented to flow into cold water pipe.
The utility model compared with prior art, solves the bathing waiting problem of storage-type thermal source, realizes and open i.e.
Heat；Solving storage-type thermal source hot water temperature being too high in pipeline in hot water circuit can not use, be asked without cold water etc. in cold water pipe
Topic, realizes while instant-heating and opens i.e. cold；Apparatus structure is simple, multiple functional, easy to operate, it is easy to install and make
With.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these all belong to
In protection domain of the present utility model.
