Abstract

The utility model relates to the field of household appliances, in particular to a gas water heater. A cold water returning gas water heater is characterized in that a water inlet pipe, a gas pipe and a water outlet pipe are arranged at the bottom of a shell; the water inlet pipe is communicated with a water inlet of a heat exchanger by a water inlet pipeline; the gas pipe is communicated with a gas inlet of a burner by a gas inlet pipeline; a gas outlet of the burner is communicated with a gas inlet of the heat exchanger; a water outlet of the heat exchanger is communicated with the water outlet pipe by a water outlet pipeline; a gas electronic proportional valve is connected with the water inlet pipeline and the gas inlet pipeline respectively; the gas water heater also comprises a return pipe and a three-way valve; and one end of the return pipe is communicated with the water outlet pipe and a spraying pipeline by the three-way valve and the other end is communicated with the water inlet pipe. The cold water returning gas water heater has the beneficial effects that the return pipe is connected to the tail end of the water outlet pipe by the three-way valve, the other end of the return pipe is communicated with the water inlet pipe, and the cold water remained in the pipeline can return to the water inlet pipe at the initial temperature regulation stage of bath, thus avoiding waste of water resources.

Description

The cold-water reflux gas heater
Technical field
The utility model relates to household appliance technical field, relates in particular to a kind of gas heater.
Background technology
Along with people's living standard is more and more higher, everybody has had further requirement to the personal hygiene problem, more than general of particularly bathing aspect has been accomplished once, so sanitary bath equipment has been had higher requirement.It is different that the water heater that uses on the market at present has more the energy of use, roughly is divided into three kinds of electric heater, solar water heater and gas heaters.Wherein gas heater is take imflammable gas: liquefied petroleum gas, artificial coal gas, natural gas etc. carry out the water heater of Fast Heating to water as fuel, have thermal efficiency height, go out hot water fast, continue constant temperature, regulate easily, the plurality of advantages such as volume is little, easy for installation, more and more be subject to vast consumer's favor.
Existing gas heater mostly is greatly Flue Gas Water Heater, and basic structure mainly is comprised of valve body assembly, burner, heat exchanger, safety device etc.Valve body assembly is being controlled the working procedure of whole water heater, and it comprises water valve, air valve, microswitch and igniter etc.When using water heater, must open first gas valve and water intaking valve.When opening water valve, the current inductor is sensed current, initial igniter and microswitch control, ignition combustion device.Combustion gas is in the combustion chamber internal combustion, and the heat of generation heats water by heat exchanger, and hot water flows out continually from delivery port.One segment distance is arranged between existing gas heater and the spray head, always retain a certain amount of cold water in this section water pipe, when water temperature was adjusted in bathing, the cold water in this section pipeline all can only bleed off, and has wasted water resource.
The utility model content
Technical problem to be solved in the utility model provides kind of a cold-water reflux gas heater, this water heater outlet end has connected a return duct by triple valve, the return duct other end is communicated with water inlet pipe, the cold water of retaining in initial temperature adjustment stage of bathing can be pipeline is all sent water inlet pipe back to, has avoided the waste of water resource.
The utility model is achieved in that a kind of cold-water reflux gas heater, comprise shell, burner, heat exchanger, water inlet pipe, Gas Pipe, outlet pipe and electronic gas proportioning valve, described water inlet pipe, Gas Pipe and outlet pipe are arranged on the bottom of shell, water inlet pipe is connected with the water inlet of heat exchanger by inlet pipeline, Gas Pipe is connected with the fuel gas inlet of burner by air inlet pipeline, the heat outlet of burner is connected with the air inlet of heat exchanger, the delivery port of heat exchanger is connected with outlet pipe by outlet pipeline, described electronic gas proportioning valve links to each other with air inlet pipeline with inlet pipeline respectively, this gas heater also comprises return duct and triple valve, described return duct one end is connected with outlet pipe and spray pipeline by triple valve, and the return duct other end is connected with water inlet pipe.
Described triple valve is three-way temperature control valve.
On the gas outlet of described heat exchanger exhaust uptake is housed, described exhaust uptake is fixed on the top of shell.
Have observation window with the burner corresponding position on the described shell.
Described side wall of outer shell offers louver(-vre).
The outlet pipe end of the utility model cold-water reflux gas heater has connected a return duct by triple valve, the return duct other end is communicated with water inlet pipe, the cold water of retaining in initial temperature adjustment stage of bathing can be pipeline is all sent water inlet pipe back to, has avoided the waste of water resource.
Description of drawings
Fig. 1 is that the utility model cold-water reflux gas heater structure master looks schematic diagram;
Fig. 2 is the utility model structural upright schematic diagram.
Among the figure: 1 shell, 2 burners, 3 heat exchangers, 4 exhaust uptakes, 5 water inlet pipes, 6 Gas Pipe, 7 outlet pipes, 8 observation windows, 9 louver(-vre)s, 10 electronic gas proportioning valves, 11 return ducts, 12 triple valves, 13 spray pipelines.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
Such as Fig. 1, shown in 2, a kind of cold-water reflux gas heater, comprise shell 1, burner 2, heat exchanger 3, water inlet pipe 5, Gas Pipe 6, outlet pipe 7 and electronic gas proportioning valve 10, described water inlet pipe 5, Gas Pipe 6 and outlet pipe 7 are arranged on the bottom of shell 1, water inlet pipe 5 is connected by the water inlet of inlet pipeline with heat exchanger 3, Gas Pipe 6 is connected by the fuel gas inlet of air inlet pipeline with burner 2, the heat outlet of burner 2 is connected with the air inlet of heat exchanger 3, the delivery port of heat exchanger 3 is connected with outlet pipe 7 by outlet pipeline, described electronic gas proportioning valve 10 links to each other with air inlet pipeline with inlet pipeline respectively, this gas heater also comprises return duct 11 and triple valve 12, described return duct 11 1 ends are connected with outlet pipe 7 and spray pipeline 13 by triple valve 12, and return duct 11 other ends are connected with water inlet pipe 5.
