Embodiment
The embodiment of the present invention is described in more detail below in conjunction with the accompanying drawings.
The problem of EMC, and conventional full wave control in safety devices such as not big wave filters be present for cutting ripple control
The problem of in the presence of flicker, can simultaneously gram the invention is intended to provide a kind of method for heating and controlling of Quick-action type (Instant heating type) water heater
Take the two problems：For compatible EMC, the present invention is controlled using all-wave, in order to test flicker problem, according to as shown in Figure 1
Condition is tested, and (we have found both at home and abroad the more severe use in ground more in the different power utilization environment of different user condition
Electrical environment) in some waveforms shown in Fig. 4-1~Fig. 4-26 are drawn after field test, these waveforms ensure water heater in work
When, lamp will not flash.
As shown in figure 1, set an experiment to be spaced apart between water heater registering one's residence to be spaced apart, two be spaced apart between using 10 meters
Electric wire (2.5mm2) 1 connection, water heater and 3 insert experiment in parallel of lamp be spaced apart after circuit on, experiment be spaced apart with water heater it
Between by 30 meters of electric wire (2.5mm2) 2 connections.Lamp can use electricity-saving lamp, incandescent lamp, find that the two can't cause reality in experiment
Test the difference of result.
Being controlled using all-wave, the voltage output ripple at two heating tube both ends is tested during to being worked under water heater different capacity
Shape, multigroup Wave data when recording lamp does not flash.26 waveforms shown in Fig. 4-1~Fig. 4-26, corresponding different equivalent work(
Rate, it is possible to achieve the mapping of power gear, further described below in conjunction with control waveform.
The sinusoidal waveform that actual situation is accompanied each other is that (cycle T for 50HZ is 20ms to electric main, and the cycle T for 60HZ is
16.67ms, this example is by taking 50HZ as an example) output waveform at heating tube both ends after the control of bidirectional triode thyristor.Different ripples
Shape length is its controlling cycle length, and solid line waveform represents conducting, and dotted line is then to be not turned on.Software controlling cycle is with T/2=
10ms is the unit cycle.The type has 2 groups of heating tubes, and upper and lower two waveforms respectively correspond to the first heating tube, the second heating tube
Output waveform.Such as Fig. 4-1 waveform represents that controlling cycle is 14 unit periods (duration 14*10ms), the first heating tube is not
Conducting, the second heating tube turn in the 1st, 4,8,11 unit periods.Fig. 4-2 waveform represents that controlling cycle is 13 unit weeks
Phase (duration 13*10ms), the first heating tube are not turned on, and the second heating tube turns in the 1st, 4,8,11 unit periods.Fig. 4's -3
Waveform represents that controlling cycle is 7 unit periods (duration 7*10ms), and the first heating tube is not turned on, and the second heating tube is the 1st, 4
Turned in unit period.Other waveforms are similarly.
Waveform shown in Fig. 4 is outlet terminal waveform, needs controlling party corresponding to controller (single-chip microcomputer) to realize.From single-chip microcomputer
I/O port to bidirectional triode thyristor control circuit as shown in Fig. 2 single-chip I/O mouth connects optocoupler U1, optocoupler U1 output control is two-way
Controllable silicon U2 conducting, bidirectional triode thyristor U2 are connected in the electric power loop of heating tube.Water heater includes the such control of two-way
Circuit, two heating tubes are controlled respectively.According to machine zero-crossing detection circuit, 10ms has a zero point, when zero point arrives
Wait, if the 10ms unit periods need to turn on, single-chip microcomputer IO provides a trigger pulse square wave, and such optocoupler will turn on
And trigger bidirectional triode thyristor conducting, bidirectional triode thyristor once turn on can maintain to next zero point arrive when and close automatically；
If this 10ms need not be turned on, single-chip microcomputer IO does not give trigger pulse in the unit period.For example to control two groups
Heating tube exports Fig. 4-1 waveform, then needs the I/O port impulse waveform respectively to control bidirectional triode thyristor as shown in Figure 3：
Two waveforms, solid line representative have pulse-triggered up and down in upper and lower two waveforms difference corresponding diagram 4-1, and dotted line is then represented and do not triggered.
The heating power control method of the present invention is described in detail as follows.
Assuming that the first heating tube (waveform in correspondence) power is P01, the second heating tube (corresponding lower waveform) power is P02,
For the controlling cycle of waveform using T/2=10ms as the unit cycle, the controlling cycle of one group of waveform is t unit period, corresponding duration
For t*10ms, the first heating tube turns on x in t unit period, and another heating tube turns on y in t unit period,
Then this group of waveform corresponds to equivalent output powers Pout=(x*P01+y*P02)/t.
Above-mentioned formula can calculate the equivalent output powers of 26 waveforms of the above, form 26 base power gears.It is right
The big situation of power step between some adjacent gear positions, in program using two adjacent gear positions within a time cycle again
Combination, so as to which a new equivalent power gear can be being produced between the two gears, to reduce difference power between gear.
Can also use the combination of third gear or more shelves for some particular points, so realize to water heater power output be slightly incremented by or
Successively decrease regulation, also just realize the stepless temperature regulating in body-sensing.
Such as：Assuming that Pa be Fig. 4-1 waveforms equivalent output powers, Pb be Fig. 4-2 waveforms equivalent output powers, Pa and
Pb combinations produce the process of new equivalent power：If it is t1 that Pa power, which performs the time, the Pb execution times are t2, then new equivalent work(
Rate Px=(Pa*t1+Pb*t2)/(t1+t2).Third gear or more shelves combine similarly, so can draw other with different time ratio
New middle power.
The power with reference to caused by above base power and combination sequences deposit form according to size order, is named as P1,
P2....PN, the lookup flow in software execution to power form are as shown in Figure 5：The power P required for heating is calculated first, from
It is small to look into power form to big, P1 is read, judges whether P<=P1, if then being heated using P1, if it is not, then continuing to look into power
Form, P2 is read, judges whether P<=P2, if then being heated using P2, if it is not, then continue to look into power form, class successively
Push away.
The present invention enables Rapid electric water heater not increasing wave filter etc. by the control signal of optimal control controllable silicon
In the case of high cost electronic component, meet EMC requirements, reduce to greatest extent when high-power water heater uses to user power utilization ring
The influence in border, and realize and adjusted close to electrodeless heating power.
