While adopting laundry washer thing, after water soaks into clothing, water level did not have clothing; Because, washing machine is to utilize friction between clothing and washing machine drum, locker room, clothing and water by clothing wash clean, if water is let slip many, between clothing not compact and cause friction reduce, its clean result is bad on the contrary, otherwise, if water level did not have clothing, clothing does not fully contact with water, causes the situation such as dry friction of clothing, clean result is not good especially, also can cause the damage of clothing.
At present, part washing machine requires controller to carry out fuzzy discrimination to the weight of clothing and material; Fuzzy detection method realizes substantially as follows: being connected on respectively on two silicon controlled output points controlling motor forward and backward by 2, is also each end points of motor forward and backward winding.When MCU disconnects after forward and backward controllable silicon, motor also can rotate because of inertia, and according to the difference of bucket clothing amount and material, inertia size is also different, and showing is exactly that the number of turns of rotating is different, and this information is read by MCU, analyzes judgement.Although the method can realize control, but the poor effect of controlling, a lot of situations all can be judged by accident, as the error of the difference of different materials and weight judgement, owing to judging the restriction of precision and control accuracy, the method can not realize the design original intention of ' water level did not have clothing, reached optimum washing state '.
Summary of the invention
Technical problem to be solved by this invention is to provide one there be not clothing to stop into water at water level, reaches the water level of washing machine automatic control system of optimum clean result.
To this, the invention provides a kind of water level of washing machine automatic control system detecting based on inflow, comprising:
Control module, for realizing the automatic control of water level of washing machine;
Water level detecting module, adopts the real-time sensed water level state of level sensor, obtains corresponding water level variable, and water level variable is sent to control module;
Inflow detection module, employing flow sensor detects the flow of inlet water at water inlet pipe place in real time, by drawing inflow and be sent to control module cumulative flow of inlet water;
Wherein, described control module comprises comparing unit, and described comparing unit is for more empty cylinder water level variable and load the loading water level variable after clothing, until load water level variable, equals empty cylinder water level variable, stops into water.
The present invention can preset the set time of a detection for the detection of water level and inflow, i.e. sensed water level variable quantity and water inlet variable quantity within the set time, by water inlet variable quantity and the ratio of water level variable, just can learn that washing drum average cross-section corresponding in this time period is long-pending, if washing drum is columniform, its cross-sectional area is a fixing numerical value; If washing drum is not columniform, within the set time, the average cross-section of empty cylinder is long-pending, water level variable and water inlet variable quantity inevitable be also one to one; Therefore, within some time periods, can be long-pending by the average cross-section of flow sensor and level sensor calculating clearancen cylinder, otherwise, by the average cross-section of empty cylinder in some time periods, amass and water inlet variable quantity, also can know its corresponding water level variable by inference.
The described set time can be set according to actual needs, and for comparing water level variable and the water inlet variable quantity in same time section, the present invention is preferably 10 seconds, and it is all very accurate that such time is set the detection of water level variable and the variable quantity of intaking.
The water level variable height that water level rises within the set time that described water position status is corresponding; Adopt flow sensor to detect in real time the flow of inlet water at water inlet pipe place, described flow sensor can be arranged on water intake valve of washing machine place, by the flow of inlet water accumulation in the set time is drawn to the water inlet variable quantity in this time period and is sent to control module; Described control module is for realizing the automatic control of water level of washing machine, and detailed control procedure is as described below.
Described empty cylinder water level variable is under empty tube shape state, the delta data of water level; Described loading water level variable is that washing drum has loaded under the state of clothing, the delta data of water level; Under the identical condition of inflow, if water does not also override clothing completely, so, clothing can produce draining in capped process, and the water level rate of climb of the rate of climb that will certainly cause water level during than empty cylinder is fast; That is to say, clothing is when just being covered completely by water, loading relation that water level variable is greater than empty cylinder water level variable will change into and load water level variable and equal empty cylinder water level variable, therefore, as long as the loading water level variable after the comparing unit of control module more empty cylinder water level variable and loading clothing, can know that whether clothing is completely awash, until load water level variable while equaling empty cylinder water level variable, illustrate that clothing is completely covered, stop into water.
When there is no clothing in washing machine, washing drum is under empty tube shape state, establishes inflow in the set time to be
, corresponding washing machine machine barrel average cross-section amasss and is
, water level variable is
, inflow is also the volume into water simultaneously, the water inlet variable quantity of empty cylinder and the pass of washing machine level change are:
.
That is to say, under empty tube shape state, no matter washing drum is cylinder or other shapes, under some heights of water level, should
data be the item that immobilizes, the variable quantity of intaking is directly proportional to water level variable, and is fixed value.
When having clothing in washing machine, to suppose in the set time, inflow is still
, clothing volume is
; In the situation that clothing is not also covered by water completely, awash clothing volume is
, not awash clothing volume is,
, wherein,
also be the displacement of volume of clothing; At this moment, water level variable is expressed as
, there is following relation:
.
Relation formula from two different conditions above can find out,
for fixed value, the washing machine of different size is just relevant with the size of washing drum,
relevant with clothing volume and inflow, and when water does not cover clothing completely, inflow is certain,
necessarily be greater than
.
Because whole inflow detects and water level detecting, by sensor, by control module, detected in real time, control module only needs judgement, SEA LEVEL VARIATION
with
whether consistent, when consistent, can be judged as water level and reach and cover clothing completely, now clean result the best.
Compared with prior art, the present invention is directed to the deficiency of the fuzzy detection method of current water level of washing machine, can reach the accurate judgement of water level, avoided the drawback of actual testing circuit complexity in prior art, by adding flow sensor at water intake valve of washing machine place, control module detects the water inlet variable quantity of washing machine, by control module, judge water level and when just do not had clothing, realize the automatic control of washing machine inflow water level, control precisely, make water level and the clothing state relation of washing machine reach optimum, realize good clean result.
More specifically, the invention has the advantages that, can application controls module accurately control height of water level, control height of water level reaches good with clothing and mates, and realizes better laundry effect, and this method algorithm is simple, is convenient to actual realization; And, compared with the Washing Machine Based on Fuzzy Control water level of prior art, introduce flow sensor, but saved controllable silicon feedback circuit, simplified program, improved control accuracy.
Preferably, described control module adopts MCU to realize the automatic control to water level of washing machine.
The present invention further adopts technique scheme, its advantage is, by flow sensor, detect the inflow that adds water in washing machine, by level sensor, detect in real time the variation of washing machine water level, adopt MCU to calculate the relation of water level variable and water inlet variable quantity, judge when water level had not just had clothing, to realize the accurate control to water level and clothing relation.
Preferably, described inflow detection module adopts the cumulative flow of inlet water of single-chip microcomputer, obtains inflow and is sent to control module.
Wherein, described flow of inlet water is the real-time water inlet data that detect, by the real time data in the set time is cumulative, just can obtain the inflow amounting in this time period.
