The utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
In attached Fig. 1 and 2, turn on the power switch 22, total intake valve 9, total water intaking valve 11, rotate thermoregulation knob 19, water temperature is set at 40 ℃, there is water to flow in the water inlet pipe 10, water touches switch 12 adhesives, press start button 18, ignition work, air valve 7 adhesives, air valve 6 is not worked, and is to close shape, combustion gas is little fiery shape through quick control valve 5 after burner 2 is lighted, this moment, high-temperature probe 4 was heated, safety valve circuit working in the accompanying drawing 2, and air valve 7 circuit pin, at this moment unclamp start button 18, air valve 6 automatic adhesives, combustion gas is by quick control valve 5 and air valve 6,7 two the tunnel merge and to be big fire burns, when this moment, water temperature rose to 40 ℃ of design temperatures, temperature probe 17 and temperature control circuit work, air valve 6 discharges, and automatically shuts down air valve 6 and air valve 7, makes combustion gas only by quick control valve 5 work, burner 2 flare are little fiery shape, at this moment water temperature descends, when the temperature of 1 ℃ of left and right sides of decline, and temperature probe 17 and temperature control circuit work, air valve 6 adhesives, combustion gas is the burning of big fire shape again, thereby realizes that the control flare is big or small and flame-out automatically, has also promptly controlled water temperature automatically.In the water yield flow rates of regulation, do not have under the significant change situation at normal hydraulic pressure, air pressure, the disposable water valve 15 of adjusting during installation, hot water outlet pipe 13 water temperature is constant even adjustment water valve 14 has changed the current size, does not need in the use afterwards to adjust.Begin in terminal procedure in the use of having a bath, the combustion gas flare can not extinguish.Just in case when no source of the gas or special circumstances occurring and extinguishing, high-temperature probe 4 safety valve circuit workings, instantaneous automatic release air valve 7 turn-offs total gas circuit, guarantees safety.
When turn-offing water valve 14, cold water matches through water valve weep of 16 inputs and the little flare of combustion gas, and this moment, water temperature was still at 40 ℃.When water valve 14 was reached maximum, water valve 15 limiting switch had limited combustion gas and have burnt to greatest extent, when the flare change frequency is the slowest, export the maximum amount of water of 40 ℃ of hot water.And water temperature can not descend because the water yield is excessive.Present the change frequency of combustion gas flare size in water valve 14 adjustment water yield sizes, thereby keep output hot water to reach constant temperature.
When using in the winter time, see Fig. 3, open total water valve 11, press start button 18, indicator lamp 31 is bright, after several seconds, and the safety valve circuit working, button is unclamped in the self-locking of relay J A circuit again.Thermoregulation knob 19 is transferred to 40 ℃ to be located, adjust air valve 5, make flare temperature probe 17 and circuit operation frequency thereof when 40 ℃ of water of output the slowest till, at this moment open hot water output change-over switch 34, to the enough bathing waters of attemperater 29 inputs, treat that ball float 30 floats, water news alarm 36 is reported to the police, and is closed in the water valve 14 of toilet, combustion gas is big fire burns, temperature knob 19 is transferred to 70 ℃, adjusts water valve 16, make the temperature control frequency the slowest till.At this moment open 28 pairs of toilet sprays of hot water output change-over switch 33 spray throwers and heat, after planting somewhat, enter the toilet, can open spray thrower 32 and use.Because 2 spray throwers use simultaneously, can not feel cold, and can solve the problem of having a bath in the family in winter fully.After the use, turn-off total water valve 11, open draining valve 33, the water emptying in the water heater prevents to freeze.
The utility model has the following advantages compared to existing technology:
1, combustion gas can two the road air inlets simultaneously, can control combustion gas flare size automatically and disembark, can not burn inaccurately because of anoxic, improve stability in use.
2, only need once adjust to 40 ℃ of scopes of design temperature, change water speed and still keep constant temperature.
3, by the quick control valve 5 of safety valve circuit control combustion gas, can make gas heater safe and reliable.
4, be provided with attemperater and 2 spray throwers in the toilet, simultaneously the hot-water spraying improves room temperature, is convenient to winter family and has a bath.
5, simple in structure, cost is low, and is safe and reliable, easy to maintenance.
