Specific embodiment
Embodiment one
As shown in Figure 1, a kind of distribution heat storage type hot water cyclesystem, uses for providing domestic hot-water for user, is applicable inIn any occasion, including water source, water heater 8 and water end is respectively used, water source can be urban water tap water, the present embodiment oneWater heater 8 be the common gas heater of family, meanwhile, also include water heater with the same function: such as air-source heatHydrophone, solar water heater, electric heater etc..
Cooling water inlet I and hot water outlet are provided on water heater 8, cooling water inlet I enters in water heater 8 for cold water and addsHeat, the hot water after hot water outlet is used to heat are discharged, and water source is connected to by cold water pipe 11 with the cooling water inlet I of water heater 8, withIt is provided with circulating pump 2 on the cold water pipe 11 that water heater 8 is connected to, flow sensing function is had on circulating pump 2, is connected at circulating pump 2There is circulation pump controller 6.
It include water tank 1, with taps 7 and terminal controller 4 with water end, water tank 1 is full water state, water tank 1On be provided with inlet and outlet I 13 and inlet and outlet II 14, with taps 7 include cooling water inlet II and hot water inlet, user's use waterWhen switch 7, be biased to cooling water inlet II, then release the water in II pipeline of cooling water inlet, when being biased to hot water inlet, then release hot water intoWater in mouth pipeline, is the prior art with taps 7, and the utility model is not described in detail.
Be connected to by pipeline with the inlet and outlet I 13 of water tank 1 with the hot water inlets of taps 7, with the cold water of taps 7 intoMouth II is connected to by cold water pipe 11 with water source, and temperature sensor I 9, temperature sensor I 9 and end-of-pipe control are provided in water tank 1Device 4 connects, and temperature sensor I 9 is used to detect the temperature of the water in water tank 1, and the data transfer that will test is controlled to endDevice 4 processed, terminal controller 4 are connect by wireless transmission method with circulation pump controller 6.
The hot water outlet of water heater 8 is connected with electric T-shaped valve 3, the other two-way of electric T-shaped valve 3 by hot-water line 10It is connect respectively with the inlet and outlet II 14 of water tank 1 and with the hot water inlet of taps 7, wherein with the hot water inlet pipe of taps 7Road is connected to the inlet and outlet I 13 and electric T-shaped valve 3 of water tank 1 simultaneously；Electric T-shaped valve 3 is connect with terminal controller 4；Electronic threeThe upstream of port valve 3 is provided with temperature sensor II 15, and temperature sensor II 15 is connect with terminal controller 4, temperature sensor II15 for detecting the temperature of the water in hot-water line, and the data transfer that will test is to terminal controller 4.
It is provided with return pipe 12 at inlet and outlet II 14 on water tank 1, check-valves 5, return pipe are provided on return pipe 1212 end is connected to cold water pipe 11.
The working method of embodiment one are as follows: use use when user needs cold water according to above-mentioned connection relationship installation equipmentTaps 7 are biased to II side of cooling water inlet, can release cold water, for users to use.
When user needs hot water, using with taps 7, it is biased to hot water inlet side, as shown in Fig. 2, hot water at this timeCircuit is water heater 8, electric T-shaped valve 3, inlet and outlet II 14, water tank 1, inlet and outlet I 13 and with taps 7, at taps 7The hot water of preferential outflow 1 middle and upper part of water tank；There is a certain amount of cold water flow in the hot-water line of 8 hot water exit of water heater,Cold water preferentially flows into the bottom in water tank 1, and the flow of water changes in water heater 8, and water heater 8 starts igniting heating,In, the flow of water, which changes, in water heater 8 forces the igniting of water heater 8 to be heated to be the prior art, and the present embodiment one is no longer in detailDescription.The igniting heating of water heater 8 flows into the cold water in water heater 8, and circulating pump 2 senses that water flow changes, and circulating pump 2 is openedWater circulation amount is accelerated in beginning work, and water flow a part flows to water tank 1 through inlet and outlet II 14, then has inlet and outlet I 13 to flow to and use waterAt switch 7, another part through return pipe 12 return to water heater circulating-heating (when with the displacement at taps 7 be less than recycle streamWhen amount), cold water is heated according to the temperature that water heater 8 is set, until reaching predetermined temperature.
The temperature sensor II 15 of 3 upstream of electric T-shaped valve detects that the water temperature flowed through at electric T-shaped valve 3 reaches preparatoryAfter the temperature value of setting, the temperature value signal that will test is transferred to terminal controller 4, and terminal controller 4 receives temperature valueSignal, the access that terminal controller 4 controls electric T-shaped valve 3 jump, as shown in figure 3, the circuit of hot water is hot water at this timeDevice 8, electric T-shaped valve 3, the hot water inlet (and water tank inlet and outlet I 13) with taps 7；During hot water flowing, hot waterA part is flowed out from from taps 7, and another part flows to water tank 1 through inlet and outlet I 13, then has inlet and outlet II 14 to flow to return waterPipe 12, then flow back to 8 circulating-heating of water heater；During this, if it is sufficiently large with 7 aperture of taps, hot water will all fromIt is flowed out at taps 7, and no longer flows to water tank 1, inlet and outlet II 14 and return pipe 12 through inlet and outlet I 13；Also, water tank 1For interior water because the water flowing of electric T-shaped valve 3 and inlet and outlet II 14 is cut off, check-valves 5 prevents the water in return pipe 12 from entering water storageTank 1, without influent source, water tank 1 under full water state will not at taps 7 outflow water.
The water in I 9 real-time detection water tank 1 of temperature sensor in the period for not using hot water, in water tank 1Temperature, and will test result and be transmitted to terminal controller 4, terminal controller 4 is previously provided with water tank water temperature threshold value, works as storageWhen water temperature in water pot 1 is lower than threshold value, terminal controller 4 issues starting circulation pump signal and gives circulation pump controller 6.
At this point, as shown in figure 4, circulation waterway is water heater 8, electric T-shaped valve 3, return pipe 12 and cold water pipe 11, hot waterThe igniting heat cycles water of device 8, when temperature sensor II 15 detects that the temperature of recirculated water reaches the preset value of water heater 8, will examineThe water temperature signal measured is transferred to terminal controller 4, and the sending switched path signal of terminal controller 4 is electronic to electric T-shaped valve 33 switched path of triple valve.
As shown in figure 5, circulation waterway is water heater 8, electric T-shaped valve 3, inlet and outlet after 3 switched path of electric T-shaped valveI 13, water tank 1, inlet and outlet II 14, return pipe 12 and cold water pipe 11, the water in water tank 1 participates in circulating-heating, until temperatureWhen sensor I 9 detects that the water temperature in water tank 1 reaches threshold value, the water temperature signal that will test is to terminal controller 4, endController 4 issues stopping circulation pump signal and gives circulation pump controller 6, and circulation pump controller 6, which receives, stops circulation pump signal, follows6 control loop of ring pump controller pump 2 stops working, and water heater 8 stops igniting heating.
Embodiment two
As shown in fig. 6, being provided with return pipe 12 at inlet and outlet II on water tank 1, check-valves is provided on return pipe 125, the end of return pipe 12 is directly connected to circulating pump 2, remaining is the same as example 1.
The above is only preferred embodiments of the present invention, is not the limit to technical solutions of the utility modelIt is fixed, it is noted that those skilled in the art can also make further under the premise of technical solutions of the utility modelImprovement and change, these improvement and change should all be covered within the protection scope of the present utility model.
