50, ensure the temperature that the water heater moment is in the environment of normal work and temperature at every moment meets user's setting.
Environment temperature sensor 65 is used for the environment temperature that detects the use environment temperature of gas heater 100 and will detect
Degree feeds back to controller 50, so that gas heater 100 can adapt to environment measuring environment temperature automatically.When environment temperature passes
When sensor 65 detects that environment temperature is more than 25 DEG C, it is just setting leaving water temperature that gas heater 100, which gives tacit consent to leaving water temperature, is not entered
Row compensates with warming；When environment temperature is at 20 DEG C -25 DEG C, gas heater 100 give tacit consent to leaving water temperature for setting leaving water temperature+
0.5℃；When environment temperature is at 15 DEG C -20 DEG C, gas heater 100 gives tacit consent to leaving water temperature for+1 DEG C of leaving water temperature of setting；When
For environment temperature at 10 DEG C -15 DEG C, gas heater 100 gives tacit consent to leaving water temperature for+1.5 DEG C of leaving water temperature of setting；When environment temperature
When degree is less than 10 DEG C, it is+2 DEG C of design temperature that gas heater 100, which gives tacit consent to leaving water temperature,.
When spring and autumn or colder wintry weather, due to the heat loss increase of hot water line, cause going out with water end (W.E.)
Coolant-temperature gage is less than the value of actual set, influences experience of taking a shower.By setting environment temperature sensor 65, gas heater can be made
100 automatically adjust carry out temperature-compensating, realize more intelligent with warming function.
If gaseous-pressure sensor 61 detects that gaseous-pressure is less than predetermined gas pressure force value, controller 50 controls combustion gas heat
Hydrophone 100 is shut down, and is avoided because gaseous-pressure is relatively low or irregular working without combustion gas state machine, meanwhile, gaseous-pressure
Fault cues device sends gaseous-pressure deficiency prompting.Thus remind user that now the failure of gas heater 100 is due to that combustion gas is low
Or without caused by combustion gas, being easy to user voluntarily to search solution.
If smoke evacuation pressure sensor detects that the smoke evacuation pressure increase of exhaust opening 421, or exhaust opening 421 have blocking feelings
Condition, now controller 50 controls blower fan 41 to raise speed, so as to supplement more air for burner 22, burner 22 is kept for one
Normal fired state.If the smoke evacuation pressure for pressure sensor feedback of discharging fume is too big, it is excessive now to illustrate that exhaust opening 421 blocks,
The rotating speed of blower fan 41 reaches the air that maximum still can not meet burning needs afterwards, and controller 50 controls gas heater 100 to stop
Machine, ensures that user is safe to use, also ensures the safety of gas heater 100.Meanwhile controller 50 controls Smoke Exhaust prompting device hair
Go out Smoke Exhaust prompting, prompt user's smoke discharging pipe to block.
If flame feedback pin 64 detects that burner 22 controls gas heater without flame, controller 50 in the course of the work
100 shut down, meanwhile, the control igniting fault cues device of controller 50 sends the fault cues of ignition electrode 23.
If the leaving water temperature that leaving water temperature sensors 63 detect is higher than setting leaving water temperature, or in a very long time
Interior leaving water temperature does not rise, and illustrates leaving water temperature exception, controller 50 controls gas heater 100 to shut down, while controller 50
Control leaving water temperature abnormal prompt device sends leaving water temperature abnormal prompt, avoids user from scalding, and ensures user's water safety.
According to the gas heater 100 of the utility model embodiment, by combustion gas, water temperature, flow of inlet water, flame, cigarette
The comprehensive detection such as road, use environment, the gas heater 100 is set to possess more preferable adaptability and security, and if
Machine can be adjusted in time during failure, and fault cues can be pointedly sent when being gone wrong after adjustment, facilitate user to search
Failure cause and solution problem.
Because the gas heater 100 can be directly fed back because of combustion gas deficiency, nothing using targetedly failure code
Combustion gas and the failure for producing shutdown, facilitate user to check, and relevant issues of settling a dispute by the parties concerned themselves, and reduce gas heater 100 after sale
The wasting of resources, lift Consumer's Experience.
According to other compositions of the gas heater 100 of the utility model embodiment and operate for the common skill in this area
