Abstract
The utility model relates to the field of household appliances, in particular to a gas water heater. The compulsive proportion mixed intake gas water heater comprises a shell, a burner, a heat exchanger, a draught flue, a water inlet pipe, a gas pipe, a water outlet pipe, and a gas electronic proportioning valve. The gas water heater also comprises an intake fan and a PLC (programmable logic controller); the burner is a sealing combustion chamber; a gas flowmeter is arranged on an intake pipeline; the intake fan is connected with the outlet end of the gas flowmeter on the intake pipeline in parallel through an air pipeline; an air flowmeter is arranged on the air pipeline; the intake fan, the gas flowmeter, and the air flowmeter are respectively connected with the PLC. As the PLC accurately controls the intake volumes of gas and air, and the gas is mixed with the air in advance, the combustion is more complete, and the thermal efficiency is also improved; meanwhile, CO is avoided from generating, and the using safety of the gas water heater is guaranteed.
Description
Technical field

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.At present the water heater that uses on the market has more the energy difference of use, roughly is divided into three kinds of electric heater, solar water heater and gas heaters.Wherein gas heater is with imflammable gas: liquefied petroleum gas, artificial coal gas, natural gas etc. are fuel carries out Fast Heating to water water heater, have thermal efficiency height, go out hot water fast, continue constant temperature, regulate easily, plurality of advantages such as volume is little, easy for installation, more and more be subjected to vast consumer's favor.
Existing gas heater mostly is Flue Gas Water Heater greatly, and basic structure mainly is made up 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 gas valve and water intaking valve earlier.When opening water valve, the current inductor is sensed current, initial igniter and microswitch control, ignition combustion device.Because the combustion chamber blow-by of this class water heater, water heater is installed in indoor, and water heater needed oxygen of when burning is also taken from indoor, the waste gas that burning is produced by flue row to outdoor, so this class water heater can not be installed in the bathroom; When air and combustion gas mixing are incomplete, not only can reduce the thermal efficiency, and the CO that generates of imperfect combustion also causes danger easily after revealing.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of pressure ratio mixed admission gas heater, and this water heater is accurately controlled the air inflow of combustion gas and air by the PLC controller, and in advance combustion gas and air is mixed, and has improved the thermal efficiency.
The utility model is achieved in that a kind of pressure ratio mixed admission gas heater, comprise shell, burner, heat exchanger, exhaust uptake, water inlet pipe, Gas Pipe, outlet pipe and combustion gas electronics proportioning valve, described exhaust uptake is arranged on the top of shell, 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 gas outlet of heat exchanger is connected with exhaust uptake, the delivery port of heat exchanger is connected with outlet pipe by outlet pipeline, described combustion gas electronics proportioning valve links to each other with air inlet pipeline with inlet pipeline respectively, this water heater also comprises air inlet blower fan and PLC controller, described burner is a sealed combustion chamber, described air inlet pipeline is provided with gas meter, described air inlet blower fan is connected in parallel on the port of export that is positioned at gas meter on the air inlet pipeline by air pipe line, described air pipe line is provided with mass air flow sensor, described air inlet blower fan, gas meter links to each other respectively at the PLC controller with mass air flow sensor.
Have observation window with the burner corresponding position on the described shell.
The utility model forces ratio mixed admission gas heater accurately to control the air inflow of combustion gas and air by the PLC controller, and in advance combustion gas and air is mixed, and not only makes burning more complete, has improved the thermal efficiency; Also avoid simultaneously the generation of CO, guaranteed the safe in utilization of water heater.
