Description
The present invention relates to a kind of combustion gas automatic control water-heater system, the gas heater of particularly a kind of temperature control heating anoxic and fault self-checking alarming, auto-control exhaust.
By the utility model patent of one of the present invention Li Huawen application, application number 87205894 combustion gas photoelectricity automatic control water heaters, realized the photo-electric control water heater automatic igniting, flame-outly refire control circuit automatically, but its function still seems single and the alarm free function.
The purpose of this invention is to provide a kind of gas heater, make it have multiple function with heating, anoxic and fault self-checking alarming, auto-control exhaust, and safer, reliable, the convenient use.
Temperature control heating of the present invention, anoxic and fault self-checking alarming, auto-control exhaust gas heater are realized with following technical scheme.
The present invention has the water heater of electronic control circuit, the heating installation of supporting installation, water pump controller, lack of water compensator, micro pump, time sealing valve, bathing operation control, use the hot and cold water change-over switch, also have automatic control exhaust fan, bathing shower nozzle and water piping system.
Electronic control circuit controlling simultaneously water heater automatic igniting, flame-out, have circuit self check fault again, anoxic alarm acousto-optic shows semiotic function; The temperature upper limit of controlling heating installation is at 60 ℃, and 40 ℃ of scopes of lower limit temperature start ventilation fan work.
Automatically light a fire in the electronic circuit, flame-out control section, by photo resistance RG as induction element through YF

13 pin output width be that two minutes high level signal makes BG8, BG9 conducting, control micro pump brownout operation, hydraulic pressure is reduced to 0.3kg/Cm in pipeline
2When following, hydraulic pressure interlock air valve is closed, burn-out, current are still in the circulation of slowing down, keep two minutes after, pump is cut off the water and is ended, and reaches the purpose of water heater overtemperature protection.
In the electronic circuit, when being operated in heating mode, the water heater burning, the amplifier output signal in two limit temperature control circuits makes relay J 1 adhesive, uses its normally opened contact, starts ventilation fan work automatically.
The mode that water-heater system of the present invention adopts main burner and bathing operation control to separate placement.The bathing operation control is placed in the toilet, and main burner is placed in ventilation, ventilate good wall or suitable place.The bathing operation control has cold water control valve, and the hot water adjusting control valve can realize that it discharges water, cuts off the water, the suitable adjustment of water temperature, the water yield.
Water-heater system of the present invention has been realized multifunction, and safety, reliable, to family's heating, bathing, washing, with fresh air with very big convenient.
Describe in detail below in conjunction with accompanying drawing:
