Description
Technical field
The present invention relates to a kind of fast gas heater, particularly a kind of can the fast gas heater of accurate temperature controlling.
Background technology
At present, family expenses fast gas heater all adopts gas ratio valve, automatic regulating gas air inflow, so as to controlling leaving water temperature.
For security consideration, gas inlet amount can not infinitely reduce, and in use procedure, the aperture of gas ratio valve lower than minimum safe aperture, still by gas ratio valve adjusting water outlet temperature, must not have following problems:
One, when inflow temperature is low (as winter), even if gas ratio valve standard-sized sheet sometimes, leaving water temperature is still too low, easily causes flu;
Two, (as summer) during inflow temperature height, even if gas ratio valve has closed to minimum safe aperture sometimes, leaving water temperature is still too high, easily scalds.
The Lingnan area many Naked of water supply line that register one's residence expose outside, greatly affected by environment, the problems referred to above performance particularly evident.
When meeting afore-mentioned, user can only manual adjustments inflow.But in a lot of situation, user debugs repeatedly, also cannot obtain suitable water temperature, not being too high, is exactly too low, and user can only pass through Body contact in advance, perception leaving water temperature, when it realizes too high or too low, had received cold or overheated inadequate stimulus.
Summary of the invention
The technical problem to be solved in the present invention how to fill up the above-mentioned blank of prior art, provide a kind of can the fast gas heater of accurate temperature controlling.
For solving the problems of the technologies described above, originally can the fast gas heater of accurate temperature controlling, comprise gas burning system, inlet and outlet system and control circuit board, wherein gas burning system comprises air inlet pipe, gas valve, combustion heat exchanger and collection fume extractor, combustion heat exchanger is furnished with igniter, described inlet and outlet system comprises water inlet pipe, heat exchange coil and outlet pipe, and gas valve is all connected with control circuit board with igniter, it is characterized in that: described outlet pipe is also provided with leaving water temperature sensors, described water inlet pipe or outlet pipe are also provided with electric control water valve and flow sensor, and leaving water temperature sensors, electric control water valve is all connected with control circuit board with flow sensor, when leaving water temperature is too high or too low, control circuit board is first by gas valve regulating gas air inflow, so as to reaching setting leaving water temperature or setting outlet water temperature range, if gas valve aperture has reached the upper limit or lower limit, but leaving water temperature is still too low or too high, then control circuit board regulates inflow by electric control water valve, so as to leaving water temperature being transferred to setting leaving water temperature or setting outlet water temperature range.
Before using, user first must set leaving water temperature or setting outlet water temperature range.After startup, control circuit board is automatically by electric control water valve and gas valve opening extremely medium aperture, intake, enter combustion gas, air is introduced while opening gas valve, igniter fire, then measures coolant-temperature gage by leaving water temperature sensors, when leaving water temperature is too high or too low, control circuit board, first by gas valve regulating gas air inflow, sets leaving water temperature or setting outlet water temperature range so as to reaching.
If gas valve aperture reaches the upper limit, but leaving water temperature is still too low, control circuit board controls electric control water valve, reduces aperture, reduces inflow; If gas valve aperture reaches lower limit, but leaving water temperature is still too high, control circuit board controls electric control water valve, strengthens aperture, increases inflow; Leaving water temperature is finally made to reach design temperature or design temperature scope.
Design like this, compensate for traditional fast gas heater dexterously and depends merely on the deficiency that regulating gas air inflow carrys out adjusting water outlet temperature, and leaving water temperature controls more accurate, and water yield is also without manual adjustment.
As optimization, it also comprises manual water valve, and this manual water valve and described electric control water valve synchronous interaction; Or described electric control water valve is also furnished with manual adjustments knob.
Design like this, user as required, first can manually be adjusted to suitable water yield, then by control circuit board automatic water temperature regulation, Appropriate application water source, avoids waste.
As optimization, described control circuit board includes limitation water outlet program, and is connected to warning device, the instantaneous velocity information that limitation water outlet program flow sensor transmits, carries out integral operation, when integral result reach limit the water yield time, reported to the police by warning device, and reduce water yield.
Design like this, is provided with predetermined water consumption during use, when water yield close to or when reaching predetermined water consumption, control circuit board sends instruction automatically, by water valve, inflow is reduced to about 4L/min automatically, and sends corresponding sound/light warning, prompting user manually closes water.
As optimization, described combustion heat exchanger is also furnished with blower fan, and the motor of this blower fan is connected with control circuit board, and controls the motor speed of blower fan by control circuit board.Design like this, in time according to temperature, runoff investigation rotation speed of fan, can ensure that fuel gas buring is abundant.
As optimization, described gas valve is electromagnetic proportional valve; Described electric control water valve is water yield servo valve, and this water yield servo valve is arranged on water inlet pipe.Design like this, it is convenient to control.
The present invention can automatically, accuracy controlling water temperature, and can constant temperature, quantitative-outlet, energy-saving and water-saving, is applicable to the various environment needing to use gas heater.
