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.
The mode that existing this type of gas heater is regulated water temperature has two kinds:
One, regulates water temperature by combustion head quantity or the combustion gas input of regulating burner;
Two, regulate water temperature by the ratio of regulating hot and cold water.
Regulate in advance when wherein the first regulative mode is bathing, the adjustable range inaccuracy, can't allow user's the water temperature of being satisfied with most, and the present main regulating measure of the second way is one group of hot and cold water hand control valve of shower nozzle below, regulative mode mainly relies on the user to realize by hand, can cause like this fluctuating temperature very large, and adjusting is very inconvenient.
Summary of the invention
Technical problem to be solved by this invention provides a kind of water heater of controlling humidity automatically, by cold water branch road in parallel on outlet pipe, valve opening on this cold water branch road is controlled according to the water temperature on the outlet pipeline by the PLC controller, make the final water that flows out of outlet pipe can keep constant temperature, improved the comfortableness of water heater.
