Detailed description of the invention
Fig. 1 is control method flow chart of the present invention.
Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, a kind of watering equipment provided by the invention into water discharge control method, watering equipment is with dish-washing machine
Example.Dish-washing machine first carries out drain operation before washing, after water on last stage is all emptied, then carries out the water inlet in this stage
Operation, after reaching the inflow of setting, washing motor is started to work, and washing water is sprayed from spray arm in dish-washing machine
Tableware washed.
It is provided by the invention into water discharge control method, as shown in Figure 1, specifically comprising the following steps:
A, setting water inlet detection time T1:
In the present embodiment, there is the time of useful signal with motor during water inlet for water inlet detection time T1.
The difference of equipment inflow, the parameter value (current value) when motor works is also different, is obtained according to test result,
When the inflow of dish-washing machine reaches inflow S1, the corresponding parameter of electric machine will appear specific variation, this inflow S1 is small
In dish-washing machine setting total inflow S, as total inflow be 2.5 liters when, inflow S1 be 1.1 liters or so, i.e., when dish-washing machine
When inflow S1 reaches 1.1 liters, the parameter of electric machine of washing motor will appear an apparent variation characteristic, will the parameter of electric machine at this time
The characterizing definition for specific change occur is motor useful signal, motor useful signal corresponding inflow S1 and setting when occurring
The time of motor useful signal appearance can be obtained in water inlet flow velocity after being divided by, which is detection time T1 of intaking, and should
Water inlet detection time T1 is stored in advance into controller.
Drain detecting step:
A draining detection time T2 is reset in water inlet detection time T1, draining detection time T2 is less than water inlet detection
Time T1, draining detection time T2 is determining according to test value and is stored in advance into controller.To draining detection time T2 when, into
Water pause, starts washing motor, detects whether motor useful signal occur by controller.
If controller does not detect motor useful signal at this time, judge to drain on last stage normally, that is, on
The draining in one stage all empties, when draining detection time T2, when inflow has not been reached yet motor useful signal and occurs
Corresponding inflow S1 continues the operation into water, executes step B.
If controller detects motor useful signal at this time, judge to drain exception on last stage, that is, upper single order
The draining of section does not arrive water inlet detection time T1, when inflow has reached or occurs more than motor useful signal without all emptying
Corresponding inflow S1 executes draining fault alarm.
When judging that draining is abnormal, in order to guarantee that detection is accurate, maloperation is avoided, further includes repeatedly detecting motor to have
The step of imitating signal.Specifically: when first time reaching draining detection time T2, such as detects motor useful signal, then carry out
Drain operation, then from from water inlet step is carried out, to when draining detection time T2, water inlet suspends for water inlet for the second time, washing electricity
Machine starting, detects whether motor useful signal occur, if motor useful signal is this time not detected, illustrates that draining is normal,
Continue to execute step B, if this time still detecting motor useful signal, then carry out a drain operation, repeat into
The step of water.Motor useful signal all only can be detected in repeated detection, be such as repeated twice detection and all detect that motor is effective
Signal, just judgement draining failure, carries out draining fault alarm.
B, water inlet detecting step
Continue to intake, to water inlet detection time T1 when, water inlet pause, start washing motor, detected whether out by controller
Existing motor useful signal.
If B1, when intaking detection time T1, controller detects motor useful signal, is judged as normal into water, after
The continuous water inlet for completing remaining inflow.
At this point, controlling remaining inflow by controlling remaining flooding time, remaining flooding time is by remaining inflow
(the total inflow S of setting subtracts corresponding inflow S1 when motor useful signal occurs) show that flow velocity t1 is divided by flow velocity t1
Inflow S1 when occurring useful signal by motor is obtained divided by water inlet detection time T1.By the way that remaining flooding time is calculated
Afterwards, it is strictly controlled and is intake according to remaining flooding time by controller, be determined as dish-washing machine at this time at the end of remaining flooding time
Inflow be set total inflow S, water inlet stop, washing motor starting, carry out washing procedure.
If B2, when intaking detection time T1, controller does not detect motor useful signal, is judged as different into water
Often.At this point, one is intaking, flow velocity is excessively slow, and one is dish-washing machines not to press setting journey there are two types of abnormal Producing reasons of intaking
Sequence is normally intake.
When judging that water inlet is abnormal, in order to guarantee that detection is accurate, maloperation is avoided, further includes repeatedly detecting motor to have
The step of imitating signal is detected 3-4 times in total that is, every the motor useful signal of detection an in setting time (such as 1-3 seconds).Only
It all can't detect motor useful signal in repeated detection, just judgement water inlet is abnormal, continues to execute following step, otherwise continues to execute
The operation of water inlet, i.e. execution step B1.
When can't detect motor useful signal by detection is repeated several times, determine that water inlet is abnormal, at this time, it may be necessary to strictly control
Flooding time processed executes repeatedly a small amount of water inlet.
Repeatedly in a small amount of water inlet step, the time intake every time presets and stores in the controller, is executing the step
When rapid, controller is carried out the time for controlling water inlet number and intaking every time by the preset period.In repeatedly a small amount of water inlet
During, every time when water inlet pause, start washing motor, detects motor useful signal.
Wherein, the time intake every time is will be by the flooding time for occurring motor useful signal under standard flow rate flooded condition
That is water inlet detection time T1 by the standard of equal part or non-equal part is divided into multistage, such as water inlet 1 second every time, calculate need in total into
Water how many times, the number of strict control water inlet start washing motor every time when water inlet pause, detect motor useful signal.
The purpose that control is repeatedly intake on a small quantity, is to be able to accurately detect out reality when useful signal occurs in motor
Corresponding inflow S1 is divided by actual water inlet total time T3 when intaking total time T3, and then useful signal occur by motor,
Calculate currently practical water inlet flow velocity t2.
Repeatedly in a small amount of water inlet step, if detecting motor useful signal, there are two types of may, one is equipment have really into
Water, but water flow velocity is slow, another kind are that equipment is not intake when starting water inlet, later multiple fill phase on a small quantity just have into
Water.
Primary judge it being into water flow velocity is excessively slow or equipment is not according to setting in this case it is desirable to additional
Determine program water inlet, specifically, equipment is first once drained, repeats the stage for executing and starting water inlet, that is, repeat step
B。
Slow if it is water inlet flow velocity, this time record detects that total flooding time of motor useful signal is obtained when advancing water
Actual flow velocity t2 obtains remaining flooding time divided by as advancing water actual flow velocity t2 with surplus water, intakes in strict accordance with residue
Time controls remaining inflow.
During repeatedly a small amount of water inlet, useful signal is still such as not detected, there are two types of may, one is water inlet flow velocitys too
Slowly, cause not detecting motor useful signal during repeatedly a small amount of water inlet, another kind is in multiple a small amount of water inlet process
In, equipment is not still intake.
In the case, then control is intake by longest flooding time, and longest flooding time is the maximum water inlet by dish-washing machine
Amount show that the maximum inflow of dish-washing machine is greater than total inflow S divided by setting flow velocity t1, and maximum inflow is dish-washing machine setting
The limiting value of maximum water inlet, i.e. can there is a phenomenon where spilling waters beyond the value.
After longest flooding time arrives, water inlet stops, and whether washing motor starting, detection motor useful signal occurs, if still
Motor useful signal is not detected, then carries out water inlet fault alarm,
At this point, if detecting motor useful signal, and motor useful signal is detected after repeatedly a small amount of water inlet above-mentioned
Situation is classified as one kind, needs additional primary to carry out that judgement is excessively slow into water flow velocity or equipment is not according to setting program
Water inlet repeats the stage for executing and starting water inlet, that is, repeats step B specifically, equipment is first once drained.
C, the step of persistently detecting:
After the completion of water inlet, equipment carries out Normal Wash, and motor useful signal is continued to test in washing process.
If can't detect motor useful signal, if still can't detect useful signal after repeatedly judging, into
Row supplement water inlet, until detecting motor useful signal again, moisturizing terminates, and continues to wash.
As described above, the plan content in conjunction with given by attached drawing, can derive similar technical solution.But it is all not take off
Content from technical solution of the present invention, according to the technical essence of the invention it is to the above embodiments it is any it is simple modification, etc.
With variation and modification, all of which are still within the scope of the technical scheme of the invention.
