Below in conjunction with accompanying drawing the utility model is elaborated.
The water route of this water heater is: water intaking valve ［ 36 ］---→ water inlet pipe ［ 5 ］---→ furnace wall ［ 8 ］---and → heat exchanger ［ 10 ］---→ hot-water line ［ 13 ］---→ water quality switch ［ 14 ］---→ water inlet sleeve ［ 12 ］---→ water tank ［ 17 ］---→ go out water mantle ［ 23 ］---→ outlet pipe ［ 22 ］---→ shower nozzle ［ 26 ］.Gas circuit is: air inlet pipe ［ 35 ］---→
Spray orifice ［ 28 ］---→ burner ［ 7 ］.Controller ［ 3 ］ is the control centre of circuit, and all the end of a thread among the figure (indicating little triangle) all join with it.Attaching plug ［ 4 ］ connects civil power.Full dose valve ［ 31 ］ and surplus valve ［ 32 ］ promptly cut-off electricity for the magnetic valve energising and promptly close.Choke valve ［ 33 ］ is the hand adjustment valve.Three air valves can be integrated.Full dose valve ［ 31 ］ is opened, and combustion gas is unimpeded; Surplus valve ［ 32 ］ is opened, the just tolerance of being passed through after choke valve ［ 33 ］ current limliting.Furnace wall ［ 8 ］ is an interlayer, and the bottom is connected with water inlet pipe ［ 5 ］, and top is connected with heat exchanger ［ 10 ］ pipeline.Water tank ［ 17 ］ is contained on the heat exchanger ［ 10 ］.Flue ［ 18 ］ passes through from water tank ［ 17 ］ middle part.One automatic shutter valve is arranged at water tank ［ 17 ］ top, is made of pore ［ 19 ］ and float ［ 20 ］.Water tank ［ 17 ］ bottom is connected with bottom tube ［ 9 ］.Bottom tube ［ 9 ］ joins by pipeline and hot water valve ［ 1 ］.Water inlet sleeve ［ 12 ］ upper end high water tank ［ 17 ］, and be connected with tank top.Have the aperture of varying level position in water inlet sleeve ［ 12 ］, go out water mantle ［ 23 ］ upper end closed, high water tank ［ 17 ］ also is connected with tank top.Go out the aperture that also has some varying levels position on the water mantle ［ 23 ］.Hot-water line ［ 13 ］ stretches into water tank ［ 17 ］ and passes through from water inlet sleeve ［ 12 ］, and tube head stretches in the vinyl cover ［ 16 ］.Having limbers ［ 11 ］ on the hot-water line ［ 13 ］ communicates with water tank ［ 17 ］.Vinyl cover ［ 16 ］ covers on the sleeve-port of the high water tank of water sleeve ［ 12 ］ ［ 17 ］ into.［ 15 ］ one on utmost point pin is fixed on the vinyl cover ［ 16 ］, and hot-water line ［ 13 ］ is stretched in the other end, but does not contact with tube wall, between utmost point pin ［ 15 ］ and the hot-water line ［ 13 ］ 10 volts to 35 volts operating voltage is arranged.Vinyl cover ［ 16 ］, utmost point pin ［ 15 ］ has constituted water quality switch ［ 14 ］ with the hot-water line ［ 13 ］ that stretches in the vinyl cover.Outlet pipe ［ 22 ］ also stretches into water tank ［ 17 ］, and stretches into out in the water mantle ［ 23 ］, and the mouth of pipe and tank top are contour, so that keep the water level of water tank, makes full use of the volume of water tank.Thermal head ［ 21 ］ and ［ 24 ］ are contained in the upper and lower of water tank ［ 17 ］ respectively, so that can obtain a water temperature signal more accurately.Gas-sensitive head ［ 25 ］ is installed on the position high as far as possible under water tank ［ 17 ］ bottom, so as can with the contacts fuel gas of leaking.Thermostatic switch ［ 29 ］ has the number retaining, is contained in the bathroom.Controller ［ 3 ］ installation site is lower, to avoid the influence of stove fire thermal radiation.The function of controller ［ 3 ］ is to handle the signal of telecommunication of thermal head ［ 21 ］ and ［ 24 ］, gas-sensitive head ［ 25 ］, thermostatic switch ［ 29 ］, water quality switch ［ 14 ］ input, break-make or other variation according to these signals of telecommunication, switch on or off the circuit of full dose valve ［ 31 ］ or surplus valve ［ 32 ］, make its unlatching or close; Give igniting pin ［ 6 ］ input high-voltage pulse current, make it, light stove fire to burner ［ 7 ］ discharge; Switch on or off the circuit of siren ［ 34 ］.In addition, controller ［ 3 ］ also provides needed operating voltage for thermal head ［ 21 ］ and ［ 24 ］, gas-sensitive head ［ 25 ］, thermostatic switch ［ 29 ］, water quality switch ［ 14 ］.
If water intaking valve ［ 36 ］ or ［ 2 ］ are opened, the water in the hot-water line ［ 13 ］ will rise to water quality switch ［ 14 ］, and flows into water inlet sleeve ［ 12 ］ through the water quality switch.In water quality switch ［ 14 ］, the hot-water line of flowing through ［ 13 ］ has become conducting medium with water between the utmost point pin ［ 15 ］, so just formed a closed circuit of being made up of water quality switch and controller ［ 3 ］, under the effect of operating voltage, faint electric current is just arranged, and promptly the signal of telecommunication passes through controller.After controller ［ 3 ］ receives this signal of telecommunication, just make igniting pin ［ 6 ］ discharge, and open full dose valve ［ 31 ］ and surplus valve ［ 32 ］ immediately, toward burner hearth ［ 27 ］ delivery of fuel gas.Combustion gas one burner ［ 7 ］ of emerging promptly contacts with electric spark and burns.Because the power supply of this water heater is a civil power, the strength of discharge and the duration of igniting pin ［ 6 ］ all can be several times as much as battery powered igniter, therefore can directly discharge to burner ［ 7 ］, and can guarantee 100% ignition success rate, and detonation can not take place.Open because of full dose valve ［ 31 ］, be the full dose firepower after combustion gas is lighted and in burner hearth ［ 27 ］, burn.If close water intaking valve ［ 36 ］ or ［ 2 ］, because the effect of limbers ［ 11 ］, water in the hot-water line ［ 13 ］ will retreat to the horizontal plane of water tank ［ 17 ］, so anhydrous outage of water quality switch ［ 14 ］, the signal of telecommunication of input controller ［ 3 ］ stops at once, controller cuts off the circuit of full dose valve ［ 31 ］ and surplus valve ［ 32 ］ immediately, makes it close, and stove fire is extinguished.This shows that the stove fire of this water heater is to play combustion with the unlatching of water intaking valve ［ 36 ］ or ［ 2 ］, close and extinguish.
Cold water is to carry out the heating first time when the furnace wall of flowing through ［ 8 ］, carries out the heating second time when the heat exchanger of flowing through ［ 10 ］, heats for the third time when the water tank of flowing through ［ 17 ］.Thermostatic switch ［ 29 ］ bath water temperature that bath person is selected is controlled ［ 3 ］ with signal of telecommunication input.When the water temperature of water tank ［ 17 ］ lining surpass thermostatic switch ［ 29 ］ during fixed temperature, the signal of telecommunication of thermal head ［ 21 ］ and ［ 24 ］ input controllers ［ 3 ］ will make the circuit of controller cut-out full dose valve ［ 31 ］, makes it close.At this moment have only surplus valve ［ 32 ］ to open, the combustion gas that enters burner hearth ［ 27 ］ only can be kept the burning of stove fire.The temperature of the water of input water tank ［ 17 ］ descends rapidly, and the water temperature in the water tank also descends gradually.When the water temperature of water tank ［ 17 ］ drop to be lower than thermostatic switch ［ 29 ］ during fixed temperature, thermal head ［ 21 ］ and ［ 24 ］ input, the signal of telecommunication of input controller ［ 3 ］ makes controller connect the circuit of full dose valve ［ 31 ］ again, make its unlatching, recover the full dose firepower, so the temperature of the water of input water tank raises rapidly, the water temperature in the water tank is also gone up thereupon.Like this, the bath water water temperature of output just with thermostatic switch ［ 29 ］ fixed temperature (i.e. bath person in the bathroom arbitrarily chosen temperature) be standard, a quite little scope, promptly bath person is insensible or do not influence in the scope of comfort and fluctuate.
Water tank ［ 17 ］ comes down to a flash vessel, and its function is that the water for different temperatures mixes space and the adequate time that provides enough, to stablize the fluctuation of water outlet water temperature.The water of different temperatures mainly is to mix by free convection in water tank ［ 17 ］ lining.When the aperture that the sometimes cold and sometimes hot water that flows out from heat exchanger ［ 10 ］ is gone up some varying levels position through water inlet sleeve ［ 12 ］ flows into water tank, increase scattered band, and certain pressure has been arranged, also can play some Forced Mixing.The bottom of water tank ［ 17 ］ and the flue that passes through from water tank ［ 18 ］ have become heating surface because of contacting with the hot gas that rises, and have also strengthened the convection current of hot and cold water in the water tank when the water in the water tank is heated.The some apertures of water through going out water mantle ［ 23 ］ of different water layers flow into outlet pipe ［ 22 ］ jointly in the water tank ［ 17 ］, also can make the water outlet water temperature further stable.Time in midwinter, if it is too low that full dose valve ［ 31 ］ cuts out the temperature of laggard water of going into water tank ［ 17 ］, after mixing, the water tank back warp still has the bigger temperature difference with hot water, cause the fluctuation of leaving water temperature to exceed due scope, at this moment can suitably transfer the aperture of big choke valve ［ 33 ］, to increase the surplus firepower, improve full dose valve ［ 31 ］ and close the temperature that the back flows into the water of water tank ［ 17 ］.Experiment shows that above measure is enough to the fluctuation of water outlet water temperature is stabilized in the receptible scope of bath person.
Gas-sensitive head ［ 25 ］ is parts of safety device.Cause gas leakage as accident extinguishing or other reason, gas-sensitive head ［ 25 ］ just has signal of telecommunication input controller ［ 3 ］, controller just cuts off the circuit of full dose valve ［ 31 ］ and surplus valve ［ 32 ］ and connects the circuit of siren ［ 34 ］, so full dose valve and surplus valve are closed, stove fire extinguishes, and siren sends audible and visible alarm.After the combustion gas of leaking was dissipated, the signal of telecommunication of gas-sensitive head ［ 25 ］ input controller ［ 3 ］ stopped, and controller just connects the full dose valve ［ 31 ］ that cuts off and the circuit of surplus valve ［ 32 ］, and with the circuitry cuts of siren ［ 34 ］, audible and visible alarm stops immediately.This moment, controller ［ 3 ］ made igniting pin ［ 6 ］ discharge igniting again if there is water to pass through water quality switch ［ 14 ］, and full dose valve ［ 31 ］ and surplus valve ［ 32 ］ are opened, so stove fire rekindles.
Bottom tube ［ 9 ］ and hot water valve ［ 1 ］ are opened this valve hot water and are flowed out through bottom tube by the bottom immediately once entering water tank ［ 17 ］ for directly raking in hot water setting.If water intaking valve ［ 36 ］ and ［ 2 ］ are closed, open hot water valve ［ 1 ］ and just the water of water tank ［ 17 ］ lining can be discharged, so hot water valve also has the function of draining valve concurrently.Hot water valve ［ 1 ］ water intaking valve ［ 2 ］ is on one side established for making things convenient for heat-obtaining water.Opening water intaking valve ［ 2 ］ during heat-obtaining water has cold water input water heater, to remove the inconvenience that bathroom into drives water valve ［ 36 ］ into from.The automatic shutter valve that is made of pore ［ 19 ］ and float ［ 20 ］ is for cooperating draining setting.When water tank was full of water, float ［ 20 ］ borrowed buoyancy to withstand pore ［ 19 ］, makes the unlikely water tank that overflows of water.Float during draining ［ 20 ］ falls, pore ［ 19 ］ ventilation, and water is discharged smoothly.
The water heater that the utility model is released has been owing to adopted an aforesaid cover operation principle, can make do not supplied water in the sizable technical scope influence of supply gas pressure of bath water temperature, is not subjected to the influence of bath water changes in flow rate.Bath water temperature is arbitrarily determined by thermostatic switch in the bathroom by bath person, and is arbitrarily changed.The work of ignition system and each control system is also irrelevant with pressure of supply water, as long as there is this water heater of minimum discharge to get final product operate as normal.Owing to adopted the structure of interlayer furnace wall, strengthened the direct heating surface of cold water, the thermal efficiency is improved.
