Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
For the ease of knowing the technical scheme of the description embodiment of the present invention, in an embodiment of the present invention, have employed the printed words such as " first ", " second " function is made a distinction with the essentially identical identical entry of effect or similar item, it will be appreciated by those skilled in the art that the printed words such as " first ", " second " are not that quantity and execution order are being defined.
Shown in Fig. 1, existing washing machine is in drainage procedure, when water level drops to reset water level, starts timing, and timing reaches draining time delay and is shut off drain valve, terminates drainage procedure.
Embodiments of the invention provide the control method of a kind of washing machine, it is therefore intended that the drainage speed actual according to washing machine dynamically sets draining time delay. Drainage speed can be defined as the ratio of displacement and water discharge time. The first definition with regard to doing in embodiments of the invention herein illustrates as follows:
Shown in Fig. 2, three water levels in outer barrel of washing machine 201 described in embodiments of the invention, including the first water level, the second water level and preset water level.First water level is less than or equal to the peak level of washing machine. Generally, the water level of washing machine includes some gears, the water yield that each gear is corresponding different. First water level is to be advisable less than or equal to the water level corresponding to lowest gear.
In drainage procedure, the water level in outer barrel of washing machine constantly declines, and in whole drainage procedure, drainage speed may be considered and is similar at the uniform velocity. From whole drainage procedure, select two stages, first stage be water level from the first water level decreasing to the process of the second water level, second stage is that water level drops to the process of 0 water level (water drains) from preset water level. Utilize two approximately equalised features of stage drainage speed, obtain:
The water discharge time of the displacement/second stage of the water discharge time=second stage of the displacement/first stage of first stage.
According to relation above, it is possible to the water discharge time going out second stage of calculating, as draining time delay. The size of draining time delay depends on the actual drainage speed of first stage but not fixed value, and drainage speed is more big, and draining time delay is more little. Dynamically setting draining time delay according to actual drainage speed, compare the way setting draining time delay as fixed value, the draining time delay of setting is more accurate.
Embodiment
Embodiments of the invention provide the control method of a kind of washing machine, are applied to the controller of washing machine, with reference to, shown in Fig. 3, comprising the following steps:
301, controller determines the first water injection time and the second water injection time.
Water injection time refers in the injecting process, and under certain waterflood injection rate, water level rises to the time shared by another water level from a water level.
Representing waterflood injection rate with C1, represent the first water injection time with ta, ta is waterflood injection rate when being C1, and water level rises to the time shared by preset water level from 0 water level.
Representing the second water injection time with tb, tb is waterflood injection rate when being C1, and water level rises to the time shared by the first water level from the second water level. Preset water level equals to or less than the second water level, and the second water level is lower than the first water level.
The water yield corresponding to one water level refers to, when the water level in outer barrel of washing machine is this water level, and the water yield in outer barrel of washing machine. The water yield can be weighed by the volume of water, quality etc.
Represent the water yield corresponding to preset water level with La, have La=ta C1.
Represent the difference between the water yield that the water yield that the second water level is corresponding is corresponding with the first water level with Lb, have Lb=tb C1, obtain:
When outer barrel of washing machine specification is determined, the water yield that certain water level is corresponding is definite value, and namely La and Lb is definite value, and therefore the ratio of ta and tb is definite value, and concrete value can record by experiment. The value of ta and the tb that experiment records can be stored by controller, or is stored as preset value by the ratio of ta and tb, reads when performing step 301.
Or, in a kind of specific embodiment, the value of ta and tb determined by controller in the injecting process. Concrete, in conjunction with the relation between the water level shown in Fig. 2, when needs water filling, controller opens water intaking valve, start timing and monitor SEA LEVEL VARIATION.
When controller determines that water level reaches the second water level, using present timing as the second water injection time, and continue timing.
When controller determines that water level reaches the first water level, using present timing as the first water injection time, stop timing.
302, the reference time is determined.
Reference time is that drainage procedure middle water level is from the first water level decreasing to the time shared by the second water level. Represent drainage speed with C2, represent the reference time with t1, have:
In a kind of specific embodiment, controller is specially one chip microcomputer (English full name: SingleChipMicrocomputer, English abbreviation: MCU), for in the memorizer of the program storage and MCU that realize the control method that the present embodiment provides, when MCU calls the program in memorizer, complete the control method described by the present embodiment.
Optionally, being provided with level sensor in washing machine, after MCU opening water discharge program, output control signal opens drain valve, determines water level according to the data of level sensor feedback, and continues sensed water level change.
In conjunction with the control flow chart shown in Fig. 4, when controller determines that water level reaches the first water level, start timing. When determining that water level reaches the second water level, using present timing as the reference time.
MCU can utilize its clock signal to carry out timing. Such as, being arranged to the depositor of timing, when drainage procedure middle water level drops to the first water level, depositor resets, and then often crossing a clock cycle register value increases by 1. When water level drops to the second water level, long-pending as the reference time using actual registers value and clock signal period (such as 0.1ms).
Step 301 and step 302 do not have sequencing.
303, according to the first water injection time, the second water injection time and reference time, it is determined that the draining time delay corresponding to preset water level.
Drainage procedure is divided into two stages, first stage be water level from the first water level decreasing to the process of the second water level, second stage is that water level is from preset water level to the process drained by water. Draining time delay corresponding to preset water level refers to, in drainage procedure, the water level that controller sets drops to the time required for 0 water level from preset water level.
Due to the drainage speed approximately equal of first stage Yu second stage, represent draining time delay with t, have:
According to equation one to equation three, obtain:
It is to say, in drainage procedure the ratio of draining time delay t and reference time t1, equal to the ratio of the first water injection time and the second water injection time in the injecting process.
Obtaining the first formula according to equation four, controller calculates according to the first formula and obtains draining time delay. Wherein the first formula is:By the first equation it can be seen thatFor definite value, concrete value can be prestored by controller, reads when calculating draining time delay t.
According to the first formula it can be seen that draining time delay was directly proportional to the reference time.
The drainage speed of first stage and second stage would be likely to occur fine difference, and this species diversity is likely to be due in drainage procedure hydraulic pressure and constantly declines to cause. Further, since the precision of level sensor is not enough or measurement time delay causes that the reference time recorded and practical situation exist certain deviation. For overcoming error that may be present in measurement process, it is possible to the first calculated result of formula is modified.
Concrete, controller calculates according to the second formula and obtains draining time delay, the second formula particularly as follows:Wherein, Δ t is correction value, and its value can be prestored by controller after recording by experiment, reads when calculating draining time delay t.
According to the second formula it can be seen that through revised draining time delay and reference time positive correlation.
304, when determining that water level drops to preset water level, timing is started.
305, the time delay when timing length reaches draining, closes drain valve.
Shown in Fig. 2, when water level decreasing to the second water level, it becomes possible to calculate according to the first formula and obtain draining time delay. Draining time delay is that water level drops to the time required for 0 water level from preset water level, and controller starts timing from water level decreasing to the moment of the second water level, the time delay when timing reaches draining, closes drain valve, and drainage procedure completes.
In conjunction with the relation between shown in Fig. 2 three water levels, the first water level is higher than the second water level, and the second water level is higher than preset water level. In a kind of specific embodiment, shown in Fig. 5, the second water level is equal to reset water level equal to preset water level.That is controller actually has only to detection and determines the first water level and reset water level. Wherein reset water level refer to water level in outer barrel just do not have in bucket ripple dish time corresponding water level.
Concrete, the first water injection time is that water level rises to the time shared by reset water level from 0 water level. Second water injection time is that water level rises to the time shared by the first water level from reset water level. Reference time is that water level is from the first water level decreasing to the time of reset water level. At once starting timing when water level decreasing is to reset water level, timing reaches time-delay closing drain valve during draining, and drainage procedure completes.
The control method of the washing machine that embodiments of the invention provide, utilize the ratio of the first water injection time and the second water injection time in the injecting process, this point equal to the ratio of reference time draining time delay in drainage procedure, obtains solving the equation of draining time delay, obtains draining time delay thus calculating.
Wherein, the first water injection time is that the injecting process middle water level rises to the time shared by preset water level from 0 water level, rises to the time shared by the first water level for water level from the second water level between the second water filling. Reference time is in drainage procedure, and water level is from the first water level decreasing to the time shared by the second water level, and draining time delay is control to calculate the water level determined to drop to the time required for 0 water level from preset water level.
It is to say, the injecting process and drainage procedure to be divided into two stages. First stage, the variable quantity of water level is the difference between preset water level and 0 water level. Second stage, the variable quantity of water level is the difference between the first water level and the second water level. In the water filling stage, the ratio of the time shared by the first stage and the time shared by second stage is definite value. Equally, bleeding stage, the ratio of the time shared by the first stage and the time shared by second stage is also definite value, and equal with the ratio that the water filling stage obtains.
Washing machine by long-term use after, its waterflood injection rate or drainage speed are it may happen that change. But, in a injecting process or drainage procedure, the ratio of the time shared by the first stage and the time shared by second stage, is an amount unrelated with waterflood injection rate or drainage speed, remaining constant, the equation therefore solving draining time delay is set up all the time.
When the water yield that preset water level is corresponding is certain, the reference time, more short expression drainage speed was more fast, and the reference time, more long expression drainage speed was more slow. Controller sets draining time delay, draining time delay and reference time positive correlation according to the reference time, and namely the draining time delay of the more fast correspondence of drainage speed is more little, and the draining time delay of the more slow correspondence of drainage speed is more big. Controller changes according to the length of reference time, dynamically set draining time delay, making draining time delay be more nearly the time that draining is actually required, thus improving draining time delay in prior art to be set to the scheme of definite value, improving the problem that draining is not thorough and loses time.
