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 in the utility model 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.
The utility model is achieved in that a kind of water heater of controlling humidity automatically, comprise shell, burner, heat exchanger, exhaust uptake, water inlet pipe, Gas Pipe and outlet pipe, 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, 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, this gas heater also comprises magnetic valve, temperature sensor and PLC controller, described water inlet pipe is connected with the water inlet of heat exchanger by inlet pipeline, inlet pipeline is provided with the cold water branch road, the delivery port of heat exchanger is communicated with outlet pipeline, is connected with outlet pipe after described cold water branch road and the outlet pipeline parallel connection; Described magnetic valve is arranged on the cold water branch road, and described temperature sensor is arranged on the outlet pipeline, described PLC controller control connection magnetic valve and temperature sensor.
Described gas heater also comprises the electronic gas proportioning valve, and described electronic gas proportioning valve links to each other with air inlet pipeline with inlet pipeline respectively.
Described PLC controller control connection burner and electronic gas proportioning valve.
Have observation window with the burner corresponding position on the described shell.
Described side wall of outer shell offers louver(-vre).
The utility model water heater of controlling humidity automatically is 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.
