Abstract
The utility model relates to a gas heater's hydrologic cycle structure contains the water tank of setting in gas heater, sets up circulating water pump in gas heater, sets up a plurality of water consuming point outside gas heater, and wherein the cold water water inlet of water tank and circulating water pump's first end feed through, and the intercommunication with cold water conduit is held to circulating water pump's second, and the hot water delivery port and the hot water pipeline of water tank feed through, and a plurality of water consuming point feed through with cold water conduit and hot water pipeline respectively, its characterized in that: cold water conduit's rivers check valve is led to in the installation by the hot water pipeline outside gas heater. Compared with the prior art, the utility model has the advantages of: through planting simple repacking, the installation feeds through the hot and cold water pipeline by the rivers check valve of hot water pipeline towards cold water conduit outside gas heater, makes the hydroenergy of hot water pipeline lead to cold water conduit, and cold water conduit's water can't flow direction hot water pipeline to it does not need the wet return to realize hot -water circulation's function to reach the house type.
Description
Technical field
The utility model is related to a kind of water circulation structure of gas heater.
Background technology
Most of families at present, family all can have multiple use water spots, and the pipeline of family is long and complex, is using gas and hot water
Before device, be full of in pipe is ice-cold running water entirely.During gas heater uses, first after drained for the cold water in pipe
Out be only hot water, the process of this row's cold water needs 15 seconds -30 seconds at least, long then will spend 5-6 minutes, mainly takes
Certainly in length and the complexity of pipeline, these cold water directly drained, serious waste water resource, with general domestic hot water
As a example device, the water averagely bleeding off in vain every time has 5～25 liters, and it uses water spot more remote with the distance of water heater, wastes just more
Seriously.Furthermore, due to the impact of water pressure fluctuations during bathing, inevitably cause fluctuation and the bathing of leaving water temperature
It is again started up occurring the phenomenon that water cut-off temperature-rising is high, the serious shadow of above series of problem due to after the closing of water heater short time in journey
Ring the bath comfort degree of user.For overcoming these defects, the gas heater with circulatory function, this combustion are occurred in that at present
Gas water heater will realize waterway circulating, needs to increase a water circulating pump in gas heater, gas heater internal and
Outside need arranges water circulating pipe, needs special return pipe to realize pipeline circulation, for big inside circulating line
How for the user of old house type, do not have return pipe in existing water piping system and reserve, so just cannot install with circulating
Water heater.
Utility model content
Technical problem to be solved in the utility model is to provide one kind also may be used without return pipe for above-mentioned prior art
Realize the water circulation structure of the gas heater of hot water circuit.
The utility model solves the technical scheme that adopted of above-mentioned technical problem：A kind of water circulation knot of gas heater
Structure, comprises the water tank being arranged in gas heater, is arranged on gas heater internal circulation water pump, is arranged on outside gas heater
Multiple use water spots, the wherein cold water inlet of water tank connected with the first end of water circulating pump, the second end of water circulating pump with cold
Waterpipe connects, and the hot water outlet of water tank connected with hot water pipeline, multiple water spots respectively with cold water pipes and hot water pipeline
Connection it is characterised in that：The water flow check valve being led to cold water pipes by hot water pipeline is installed outside gas heater.
As improvement, described water flow check valve be arranged on from gas heater farthest with water spot away from hot water pipeline with cold
Between waterpipe.
Improve again, the pipeline between the cold water inlet of joining water box and the first end of water circulating pump is provided with discharge
Sensor
Compared with prior art, the utility model has the advantage of：By planting simple repacking, outside gas heater
The water flow check valve being led to cold water pipes by hot water pipeline is installed, connects cold hot water piping, so that the water energy of hot water pipeline is led to cold
Waterpipe, the water of cold water pipes cannot flow to hot water pipeline, does not need return pipe to realize the work(of hot water circuit thus reaching house type
Energy.
Brief description
Fig. 1 is the water circulation structure schematic diagram of gas heater in the utility model embodiment.
Specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
The water circulation structure of gas heater as shown in Figure 1, comprises the water tank 2 being arranged in gas heater 1, setting
In gas heater internal circulation water pump 3, it is arranged on the multiple use water spots 4 outside gas heater 1, with the fire hose can be installed at water spot
Head or other water outlet equipments, the wherein cold water inlet of water tank 2 is connected with the first end of water circulating pump 3, and the second of water circulating pump 3
End is connected with cold water pipes 5, and the pipeline between the first end of the cold water inlet of joining water box 2 and water circulating pump 3 is provided with
Water flow sensor 8, the hot water outlet of water tank 2 is connected with hot water pipeline 6, multiple water spots respectively with cold water pipes 5 and heat
Waterpipe 6 connects, from gas heater farthest with water spot away from hot water pipeline and cold water pipes between be provided with by hot water
Pipeline 6 leads to the water flow check valve 7 of cold water pipes 5.
During use, after water circulating pump 3 starts, the water in cold water pipes 5 is pumped in gas heater 1 by water circulating pump 3
Water tank 2 heated, the water after heating flows to hot water pipeline 6 from the hot water outlet of water tank 2, then through water flow check valve 7
Continue towards cold water pipes 5, the water tank 2 then proceeding to be pumped to by water circulating pump 3 in gas heater 1 is heated, and so follows
Ring, until the water in cold water pipes 5 and hot water pipeline 6 all reaches design temperature, tap starts hot water.
Claims (3)
1. a kind of water circulation structure of gas heater, comprises the water tank being arranged in gas heater, is arranged on gas and hot water
