Background technology
At present, the central gas heater that occurs on the market (as water heater more than 16 liters) can realize that multiple spot supplies water, can 2,3 even more with water spot, and its external pipeline system is complicated, and the water route is many.When water heater was not worked, the water in the exterior line all was cold water, in use, must drain the cold water in these pipelines, just can obtain hot water, and this process was generally wanted more than tens seconds.Two problems are arranged during therefore central type water heater multiple spot supplies water and uses: one, the waste of aqueous vapor electricity: the cold water in the pipeline generally can not be done bathing and use, and generally is directly to emit, and causes water resource waste; After water heater was finished using, because pipeline is long, what stop in the pipeline all was hot water, and these hot water will slowly cool off under nature, was discharged before using next time, and therefore, these hot water all are wasted, and have also just wasted water, electricity, combustion gas.Its two, inconvenience: because the discharging of cold water is generally wanted tens seconds in the pipeline, therefore, in use need the wait of long period, it is uncomfortable convenient to use.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, easy to use, and ensure that effectively the water in the water heater exterior line can maintain the water circulation type digital thermostat gas instantaneous water heater of certain temperature range.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of water circulation type digital thermostat gas instantaneous water heater, comprise housing, water heater main body and be connected in external pipeline system on the water heater main body, this external pipeline system mainly is made of water pipeline and inlet pipeline, it is characterized in that: described water pipeline is connected with inlet pipeline and is combined as sealing backwater structure, be provided with water circulating pump between water pipeline and the inlet pipeline, the water inlet of water circulating pump is provided with check valve.
As further specifying of such scheme, the link position of described water pipeline and inlet pipeline is provided with triple valve, the external domestic water water pipe of inlet pipeline.
Described water heater main body mainly is made of gas ratio valve, pipeline, water proportioning valve, burner, heat exchanger, blower fan, and the each several part member interconnects and is arranged in the water heater housing.
Described water pipeline is provided with the one or more water spot of using.
Described inlet pipeline, triple valve, water proportioning valve, heat exchanger, water pipeline, water circulating pump connect as one successively, and three ports of triple valve are connected with inlet pipeline, water proportioning valve and water circulating pump respectively.
Described water pipeline is provided with temperature sensing device, the external control device of this temperature sensing device.
Described water pipeline is provided with relief valve, this relief valve and the corresponding connection of control device on the temperature sensing device.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
1, the utility model adopts sets up a water circulating pump on the basis of conventional water heaters structure, be connected with inlet pipeline with the water pipeline and form a return water system, make water heater in the non-use period, if water temperature is lower in the exterior line, then water circulating pump is under the control of control system, can turn round voluntarily, power is provided, the water in the return water system is circulated, the burner of water heater burns simultaneously, backwater is heated, thereby, make the water in the outside water pipeline maintain certain temperature range all the time, the user at any time opens and uses water spot, can obtain hot water, the problem that central gas heater multiple spot supplies water obtains perfect the solution.
2, the water inlet of water circulating pump of the present utility model is provided with check valve, and in the time of can preventing the work of bathing water system, bathing water wherein enters return water system, and is simple in structure, safe and practical.
3, on the water pipeline of the present utility model temperature sensing device and relief valve are set, the water in the effectively anti-locking system is heated back volumetric expansion, increased pressure, with the hydraulic pressure in the alleviation system, and protection water heater and water circuit system.
