The utility model is described in further detail below in conjunction with drawings and Examples.
On the right side of housing 1 electric-controlled box 7 is housed; transformer 11 outside the crust body 1 in parallel; plug 10; in the lower right of housing 1 air valve 12 is housed; air valve 12 is by conduit 76 and burner 13 UNICOMs; igniting pin 8 is arranged in the burner 13; flame test bar 9 is equipped with water valve 15 in the lower left of housing 1, and water valve 15 is by penstock 77 and heat exchanger 6 UNICOMs; fin 78 is equipped with on heat exchanger 6 tops; heat exchanger 6 left sides have outlet pipe 74 and with outlet valve 14 UNICOMs, the top of housing 1 is equipped with and is forced air draft mechanism 75, forces air draft mechanism 75 by fan housing 4; blast protection 3, smokejack 2; motor 50 is formed.
During use, plug 10 is inserted power supply, connect transformer 11, after voltage is reduced to 42V by 220V, input electric-controlled box 7; Rotate turn-knob 25, tolerance adjusting rod 26 on the air valve 12, electric-controlled box 7 sends instruction simultaneously, connects the coil 22,32 of magnetic valve 57,61 and produces the magnetic field boundary; When combustion gas by air inlet pipe 16, when air flue 60 enters air flue 79, magnetic valve 57 at first enters duty, picks up armature 31, open air chamber, combustion gas enters air flue 58,59, and magnetic valve 61 enters duty then, pick up armature 21, open air chamber, combustion gas enters air flue 62,63,64, and enters burner 13 by conduit 76, igniting pin 8, the flame test bar is started working, and lights combustion gas, and water heater is in quasi-operating status; Meanwhile, open the adjusting screw(rod) 37 on the water valve 15, current are by water intaking valve 33, water channel 66, and current are by screen pack 34, magnet 35, filter, magnetization is laggard goes into water channel 67, washes magnetic then open and hangs piece 38, enters water channel 68; Touch sensor 40 simultaneously, produce the signal of telecommunication and be transferred to electric-controlled box 7, electric-controlled box 7 produces the synchronous UNICOM of clock signal air valve 12; After current enter water channel 69,70, flow in the water channel 71 by rill water channel 41, big flowing flux 44, discharge is by turn-knob 45, adjusting screw(rod) 46 controls, after mixing up, plays by current stabilization adjusting rod 48 control flow stabilizing valve 51 and low hydraulic pressure priming, after current enter water channel 69 once more by water channel 71, the flow stabilizing valve 51 of will getting excited, spring 56 shrinks, spool 54 is opened, and current enter not road 72, delivery port 80, conduit 77, and current enter heat exchanger 6 then, heated hot water enters outlet valve 14 by conduit 74 and flows out, and uses.
During use; open water valve 15; in the time of air valve 12, force air draft mechanism 75 to start working, motor 50 runnings; burnt gas is by fan housing 4; smokejack 2 is discharged outdoor, and air channel protective device 3 plays the safeguard protection effect, in case motor 50 stalls or flue 2 stop up; air channel protection 3 can be sent signal to electric-controlled box, stops the complete machine running.
Because 2 cover magnetic valves 57,61 are housed on the air valve 12, tolerance can more effectively be controlled, the unlikely leakage of combustion gas reaches the purpose of duplicate protection.
Because water valve 15 has been set up water intaking valve 33, and carry out current by screen pack 34 and filter, dirt, impurity can not enter water heater in the water, the current cleaning; Current are magnetized by magnet 35 again after filtering, and make water quality good, and health protection and therapeutic action is arranged; Be provided with rill water channel 41 and big flowing flux 44 in the throttling valve plug 73, the flow of water can more effectively be controlled and regulate to promptly dual water channel, and unlikely generation is excessive or too small; Throttling adjusting screw(rod) 48 can be controlled flow stabilizing valve 51, makes the low hydraulic pressure starting of water heater.
In the use, also can and close and control burning and stop burning, when cutting off the water supply by the logical of control water, magnetic in the water valve 15 is hung piece 38 and is separated with sensor 40, produces the signal that closes and gives electric-controlled box 7 and send instruction, closes the magnetic valve 57,61 on the ACV Air Cut Valve 12, turn-off source of the gas simultaneously, burn-out; When water flowing again, current impulsion magnetic is hung piece 38 and is connected with sensor 40, produces logical signal and gives electric-controlled box 7 and send instruction; connect source of the gas, combustion gas enters burner 13, gets final product flow heated water; simultaneously, force air draft mechanism 75 and inner room overheat protector 5 to turn round together.
When not in use, rotate turn-knob 25, tolerance adjusting rod 26 on the air valve 12, turn-off source of the gas, can close water valve 15, motor 50 and power supply simultaneously.
The utility model is rational in infrastructure, and is easy to use, the aqueous vapor interlock, and duplicate protection, the safety coefficient height can be widely used in domestic water, industrial hygiene, the use of food and drink restaurant, is suitable for shower, bath in a tub, washing especially.
