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.
