Be example with Fig. 3 scheme below, illustrate the utility model is how to realize its purpose:
When water intaking valve [1] when opening, the water in the water route just begins to flow, and the water of hot-water line [14] lining just can rise to the water-control switch place, and emerges from the hot-water line tube head, flows into water tank [9] through water retaining cover [13] and sleeve [16] again.In water-control switch, this anhydrous linking to each other between probe [12] and the hot-water line [14], be state of insulation, but be full of the water that flows this moment, constituted with water is the conductive path of conductor, so just voltage is imported electronic relay [35], make main circuit open-minded, to little magnetic valve [26], ignition controller [33] and water temperature selector switch [2] power supply.The probe that the water temperature selector switch passes through electric current to be connected is again imported main solenoid valve [3].At this moment, ignition controller [33] gets electric work, order igniting pin [34] discharge, main solenoid valve [3] and little magnetic valve [26] also must be established by cable and open, the combustion gas of A air chamber just enters the B air chamber by two magnetic valves, enter burner [6] through air flue [23] and spray orifice [5] again, in burner hearth [21], meet then and burn with igniting needle-discharging electricity orphan.In case stove fire is lighted, inductive needle [32] promptly can be heated and produce signal of telecommunication input ignition controller [33], and order igniting pin [34] stops discharge.If close water intaking valve [1], because the effect of limbers [17] and passage [15], water level in the hot-water line [14] just can retreat to the horizontal plane of water tank [9] rapidly, water-control switch promptly can cut off the power supply because of anhydrous, the circuits for triggering of electronic relay [35] are cut off, main circuit disconnects immediately, and two magnetic valves [3] and [26] are closed thereupon, and stove fire extinguishes.As seen, stove fire is to play combustion with the unlatching of water intaking valve, closes and extinguishes.After water intaking valve [1] was closed, ignition controller [33] also quit work with the disconnection of main circuit, and water heater just is stopped status.
After the start, the water that flows in the water route is heating up rapidly when over-heat-exchanger [10].Locate in thermometric chamber [18], when in a single day water temperature reaches the temperature that sets (break-off signal of the probe that the water temperature selector switch is connected), corresponding probe just disconnects the circuit of main solenoid valve [3], main solenoid valve promptly cuts off the power supply and closes, stop air feed, little magnetic valve this moment [26] still is opening, continues air feed.Since little magnetic valve [26] the gas flow that can pass through only can keep the burning of stove fire, the burner hearth firepower subtracts suddenly, water temperature descends rapidly.When the water temperature of the thermometric chamber [18] of flowing through was reduced to the closed temperature of probe, probe was closed, and main solenoid valve [3] must be established main opening by cable, and to burner hearth [21] input combustion gas, burner hearth recovers firepower again, and water temperature is gone up immediately.When the hot water of heating through this batch (-type) flows into water tank from sleeve [16], a comparatively significantly fluctuating temperature (promptly the break-off signal with probe is the upper limit, and closed temperature is the variation of lower limit) is arranged still.Water tank [9] is a flash vessel, and the hot water of different temperatures has enough spaces and adequate time to mix at this, to eliminate this fluctuation, further stablizes water temperature.The position of outlet pipe [8] mouth of pipe in water tank higher [near the top of water tank] can keep the water level of water tank, makes full use of the volume of water tank.
In Fig. 4 scheme, the water temperature of thermometric chamber [18] of flowing through popped one's head in [37] convert signal of telecommunication input temperature controller [38] to, water temperature selector [39] is also imported temperature controller [38] with the corresponding electric signal of the selected water temperature of bath person, temperature controller just is switched on or switched off the circuit of main solenoid valve [3] frequently according to these two input signals, make main solenoid valve open frequently or close, the same with Fig. 3 scheme, in intermittently mode to the burner hearth air feed, thereby control the burner hearth firepower, reach the purpose of heating and temperature control.Compare with Fig. 3 scheme, Fig. 4 scheme can realize electrodeless or select temperature.
Two-way valve [25] has two paths, and two passages open and close simultaneously, is connected with running water pipe with water inlet pipe [22] respectively as the passage of intaking, and the passage that is used as water outlet is used for the water pipe that hot water is drawn is joined with a drainpipe [20] and a trifle respectively.Two-way valve is to establish for ease of obtaining hot water, if open this valve, cold water is just imported water heater by intake tunnel through water inlet pipe [22], flows in the water route, and water heater promptly enters duty.Meanwhile, hot water is flowed out by drainage channel through drainpipe [20].If close two-way valve, the water route stops to flow, and water heater promptly is stopped status.As seen, handle this valve and also can start water heater, and can directly obtain hot water.Drainpipe [20] slightly stretches into water tank bottom, is in order to make water tank keep micro-water level, in order to avoid the dehydration dry combustion method.Overflow valve [24] links to each other with drainpipe [20].Overflow valve plays the pressure limiting effect, if the hypertonia in the water route, overflow valve is just opened automatically, and the draining decompression is so that water heater avoids the damage that overload pressure causes.Overflow valve also can manual control be opened valve, and the water in the water tank is discharged.
Owing to adopted above-mentioned principle and scheme, the water heater that the utility model is released also has following characteristics except that the function that possesses the automatic igniting of existing gas heater and stop working:
One, can be on the selected temperature of bath person with water temperature stability.
Two, water temperature is not subjected to the influence that discharge changes, and is not subjected to the influence of tap water pressure and gaseous-pressure nature disturbance yet.
Three, in the shower process, bath person also can arbitrarily change bath water temperature by the water temperature selector switch (or water temperature selector) that is contained in the bathroom.
Four, no minimum discharge restriction can start as long as the water route has water to flow, and keep normal operating conditions.
Five, the thermal efficiency is apparently higher than existing gas heater.
