The course of work combination accompanying drawing 1 of the digital temperature control siphon heating electric water heater of the present invention is described as follows:
1st, it is vented:Water is set to drain the air in heating circuit, mixed circuit respectively with 0.5~6bar gauge pressures, it is straight per road
Respective valves are turned off after to complete water outlet.
2nd, static preheating, heat-accumulating process:Switch on power and start the present invention, the top surface upper outlet 4-2 of siphon heat storage tank 4
Locate the temperature sensor 8 set, when perceiving water temperature and being less than 92 DEG C, continuous heating after electric heater 4-4 connected by closed-loop control,
Electric heater 4-4 is then disconnected until upper water is heated to 97 DEG C, wherein when temperature sensor 8 perceives water temperature more than 92 DEG C, control
Hot water signal lamp 4-11 shows hot water conditions, and hot water supply function.Continuous heating is waited to hot water signal lamp 4-11 recovery high temperature
Hot water heat storage state.
3rd, the instant heating process of dynamic:During using hot water, upper water conservancy flows through safe sluicing non-return with its 0.5~6bar gauge pressure
Valve 3, and in 92 DEG C of mixed water threeways 5 of high-temperature-hot-water press-in in siphon heat storage tank 4, mix what is set on water pipe 5-1 by normal temperature
Bypass valve 5-2, by mix water threeway 5 outlet set temperature sensor 8, come automatically adjust heating tank high temperature hot water with
Mixed proportion between 20 DEG C of upper water, with hot water outlet temperature after constant mixing at 45 DEG C or so, and by mixing going out for water threeway 5
Mouth discharge, and continue to be mixed into 34-42 DEG C of bath hot water with water on 20 DEG C for using in user terminal.
Due to avoiding hot water from flowing through valve body, improve the heat dissipating state of stepper motor, and delay the aging of rubber seal
Process so that in 15 years life cycles of electric heater, without changing regulating valve, greatly improve the reliable of electric heater product
Property.
The temperature value of the mixed hot water outlet sensor 8 of water threeway 5 is set as relatively low 45 DEG C, then when siphon heat storage tank 4
Middle hot water temperature constantly reduces, so that it may progressively turns down bypass valve 5-2, automatically adjusts between cooling hot water and 20 DEG C of upper water
Mixed proportion, continue hot water outlet temperature after constant mixing;Until hot water temperature is down to 45 DEG C and closes bypass valve 5-
2, the heat of hot water is individually only discharged by siphon heat storage tank 4, until hot water use finishes;So as to thoroughly discharge its amount of stored heat,
With minimum water tank volume, realize that amount of stored heat maximizes.
And the temperature sensor 8 set at the top surface upper outlet 4-2 of siphon heat storage tank 4 perceives water temperature and is less than 92 DEG C
When, connect electric heater 4-4 and adjust heating power to maximum, then by static state preheating, heat-accumulating process, switch to dynamic heating immediately
Process, progressively discharge hot water accumulation of heat by the quick instant heat hot water of tube type electric-heating pattern, while by siphon heat storage tank 4
Amount, and be equipped with bypass valve and realize automatic water-mixing, constant hot water outlet temperature;Heating process is persistently carried out, until closing heat
Water function, it is transferred to static preheating, heat-accumulating process.
4th, defencive function:
(1) anti-dry:When the water level that dry burning resistance switch 4-8 is perceived in siphon heat storage tank 4 is not yet full of, to prevent
Electric heater 4-4 damages because of dry combustion method, will automatically cut off complete machine power supply, into guard mode, until water level heats full of siphon
Heat-accumulator tank 4, it can automatically reset;(2) superpressure preventing:When upper water meter is pressed more than 6bar, safe sluicing check-valves 3 can pass through water conservancy diversion
Pipe releasing pressure automatically, protect the safe to use of siphon heat storage tank 4;
(3) anti-electricity wall:A nonmetallic resistance electric-type pipe fitting is respectively set to make in the exit of upper water inlet 1 and mixed water threeway 5
It is safe to use to ensure for anti-electric divider wall 4-9;
(4) it is anticreep:On the basis of safety ground of the present invention, when leakage protection switch 4-10 built in undesirable mutual electromagnetic inductance formula is examined
Measure leakage current and exceed human body sensing scope, power supply will be automatically cut off in 0.01~0.1 second, while by heating signal lamp
4-7 flashes, and to show failure, ensures human-body safety.

The temperature sensor of outlet, to automatically adjust the mixed proportion between heating tank high temperature hot water and upper water, with constant mixing
Hot water outlet temperature afterwards.
2nd, hot water is avoided to flow through valve body:Improve the heat dissipating state of stepper motor, and delay the aging of rubber seal to enter
Journey so that in 15 years life cycles of electric heater, without changing regulating valve, greatly improve the reliability of electric heater product.
3rd, amount of stored heat maximizes:Hot water outlet temperature is set as relatively low 45 DEG C, then when hot water in siphon heat storage tank 4
Temperature constantly reduces, so that it may progressively turns down bypass valve 5-2, automatically adjusts the mixing ratio between cooling hot water and 20 DEG C of upper water
Example, continues hot water outlet temperature after constant mixing;So as to thoroughly discharge its amount of stored heat, with minimum water tank volume, accumulation of heat is realized
Amount maximizes.
4th, siphon circulation electrical heating pattern:The siphon set bucket set in vertical heating tank, in static state preheating, heat-accumulating process
Siphon circulation electrical heating pattern is formed, intermediate temperature regenerator is held outside high-efficiency heating, bucket wherein in bucket.
