Of course the main wash step also has its own drain, the drain listed here being mainly that of the rinse step, the separate listing being for the purpose of illustrating the defoaming procedure mentioned later; dehydration may not be required in some laundry processes; the washing process may include three steps of rinsing, draining and dewatering, i.e. rinsing and dewatering for several times to reach the aim of complete cleaning.
As shown in fig. 7 and 8, a general washing machine includes: s41, in the step-up stage, the dehydration starts to increase from zero to the target rotation speed R max The method comprises the steps of carrying out a first treatment on the surface of the S42, maintaining the target rotation speed R in a steady speed stage max For a period of time; s43, a deceleration stage, from the target rotation speed R max Reducing the speed to zero; s44, ending the stage, and completing dehydration; it should be noted that, the dewatering process of the related washing machine process may have multi-stage speed-up, speed-stabilizing and speed-down processes, and the defoaming working condition judgment related to the invention may be the relation between the judgment and the speed-stabilizing rotation speed in each speed-up, speed-stabilizing and speed-down stage; or take the initial 0 speed to the highest rotational speed (target rotational speed R max ) In this section, the speed is increased in a normal sense from the highest rotational speed (target rotational speed R max ) The section of the speed reduction is taken as the normal meaning until the speed of 0 is ended, and after the dehydration and defoaming process in the stage is executed, the dehydration and defoaming process can not be executed any more if the condition is met in the stage, so that the water source and the washing time are saved.
As shown in fig. 2, the defoaming method for a washing machine provided by the invention comprises the following steps:
s100, data acquisition, including acquiring a washing program input/selected by a user;
s200, judging conditions, including judging whether an executable dehydration program is configured in the washing program;
S300, performing control including performing a drainage defoaming process (as shown in fig. 3 and 4) when there is no dehydration process to be performed, or ending washing (as shown in fig. 5) when there is no dehydration process to be performed after the drainage defoaming process is performed, wherein the drainage defoaming process is to perform foam flushing in drainage; when a dehydration program to be executed exists, executing a dehydration and defoaming process (shown in fig. 3, 4 and 5), wherein the dehydration and defoaming process is to execute foam flushing in dehydration, and whether a user selects to perform dehydration or not is judged to determine whether defoaming work is needed in the drainage process or not; the washing machine has the advantages that the washing machine can be used for defoaming in drainage when a washing program without a wrong dehydration process is arranged, defoaming can be carried out in the whole washing process, the door body and the door seal are kept clean, mildew and bacteria are prevented from growing on the door seal, clothes are kept sanitary, and the use experience of a user is enhanced; it is of course also possible to arrange to perform defoaming in the drain water, and to determine whether to end washing or to continue defoaming in the drain water according to whether or not dehydration is required, so that drainage defoaming and dehydration defoaming can be performed in the washing process with dehydration, and the defoaming effect is enhanced.
Specifically, whether the washing process needs to be dehydrated or not can be obtained in the whole washing process, whether the dehydration exists or not is judged, or the judgment of certain parameters in the dehydration, such as dehydration status code, dehydration time and dehydration target rotation speed R max Etc., most directly the spin-drying target rotation speed R which the user will input/select in a general laundry process max In a specific method, the data acquisition may include acquiring the dewatering target rotation speed R input/selected by the user max The method comprises the steps of carrying out a first treatment on the surface of the Condition judgment including judgment of dehydration target rotation speed R max Whether or not to be equal to zero; executing control including, if the dehydration target rotation speed R max When the rotational speed is equal to zero, the drainage defoaming process is performed (as shown in fig. 3 and 4), or the target rotational speed R is set after the drainage defoaming process is performed max Ending the washing when equal to zero (as shown in fig. 5), wherein the drainage defoaming flow is to perform foam flushing in the drainage; if the dehydration target rotation speed R max Performing a dehydration and defoaming process (shown in fig. 3, 4 and 5) when the water is not equal to zero, wherein the dehydration and defoaming process is to perform foam flushing in dehydration; it should be noted that the dehydration target rotation speed R max For user to select preset target rotation speed for washing process or target rotation speed for user to modify, i.e. highest rotation speed, target rotation speed R for general washing machine max 400, 600, 800, 1000, 1200, etc., in units of R/min, wherein the dehydration target rotation speed R is input/selected by a user by judging max Whether the judgment is equal to zero can be directly reflected, so that the effect of the mode is achieved.
In a corresponding embodiment, specifically, the drainage defoaming process may be that after drainage begins, the drainage instant water level H is obtained; judging whether the water level H is equal to the first flushing water level H 1 The method comprises the steps of carrying out a first treatment on the surface of the When the water level H is equal to H 1 Time pieceFlushing by foam when the water level H is not equal to H 1 The water is continuously drained, and after foam flushing is performed, the water can be continuously drained for a period of time or stopped; wherein the instant water level H of the drain is measured by a drain pump pressure sensor or a water level sensor, e.g. a drain pump pressure sensor, measured in Pa, the first flush water level H 1 The pressure of the drain pump may be set to be 0Pa (i.e., when there is no water in the drain pipe when draining after rinsing) or other drain pump pressures set according to experiments; it is known that the water level H gradually decreases as the water discharge proceeds, and decreases to the first flush water level H 1 When the foam flushing is carried out, if the foam flushing is not achieved, the water is continuously drained; it should be noted that the foam flushing, due to the water flow impingement, suddenly increases the pressure of the drain pump, so that the water level H indicated here is equal to the first flushing water level H 1 For the first time the water level H reaches the first flushing water level H 1 Or after the foam flushing is performed once, the water level judgment and the foam flushing are not needed to be performed in the drainage stage. In the drainage defoaming flow, the water level judging method (drain pump pressure) is adopted to directly reflect the time when foam needs to be washed, especially when the drain pump pressure is set to be 0Pa, foam is washed after the drainage is finished, the final drainage work is finished, and the washing effect is good.
In a corresponding embodiment, the dewatering and defoaming process comprises: a second dehydration defoaming process, namely, executing foam flushing in a dehydration steady-speed stage or a dehydration deceleration stage of dehydration; the dewatering, shown in fig. 7, i.e. the foam flushing is performed in two stages, steady or slow down, so that all foam generated before flushing can be completed.
In a corresponding embodiment, more preferably, the second dewatering and defoaming process may be to perform foam flushing at the end of the dewatering and stabilizing stage or at the beginning of the dewatering and decelerating stage, i.e. at time t2 shown in fig. 7, so that foam generated during the stabilizing stage can be guaranteed to be flushed away without affecting the efficiency of the decelerating stage.
In a corresponding embodiment, the second dewatering and defoaming process is more specific and can be that the dewatering rotating speed reaches the dewatering target rotating speed R max After that, the dehydration is obtainedAn instant rotation speed R; judging whether the instant dewatering rotating speed R is equal to the second flushing rotating speed R 2 The method comprises the steps of carrying out a first treatment on the surface of the When the instant rotation speed R of dehydration is equal to R 2 Foam flushing is performed at this time, wherein a second flushing rotational speed R 2 Is smaller than the target rotation speed R of dehydration max Is a threshold value of the dehydration target rotation speed R max A target rotational speed of the dehydration step input/selected for the user; since the speed is a shaking interval amount during the dehydration of a general washing machine in a steady speed stage, the dehydration target rotation speed R max Generally refers to the average value of the amount of the area, and in order to achieve a better foam flushing effect, the influence of the amount of the area is prevented, and the condition thereof can be set to be smaller than the target dehydration speed R max Optimally the lower limit of this interval amount; of course, this value is generally determined experimentally and is correlated with the corresponding target rotational speed R max Concerning, e.g. target rotational speed R of dehydration max At 600, a second flushing rotational speed R may be set 2 =500, or e.g. setting a functional relation R 2 ＝bR max B is an experimentally determined constant of 0 < b < 1. Through the relation of the speeds, whether the dehydration speed stabilization stage is finished can be directly judged, or the dehydration speed stabilization stage is finished can be determined according to the drying time set by a washing program, the speed reduction of a motor, the change of acceleration and the like.
In a corresponding embodiment, the foam flushing step may be performed in the dewatering and defoaming process by adding a first dewatering and defoaming process before the second dewatering and defoaming process, i.e. in the dewatering and speed increasing stage or the dewatering and speed stabilizing stage of dewatering, as in the dewatering and speed increasing stage shown in fig. 7.
In a corresponding embodiment, it is more preferable that the first dewatering and defoaming process may be to perform foam flushing during or at the end of the dewatering and rising stage (the beginning of the steady-speed stage), i.e., at time t1 shown in fig. 7, so that it is ensured that foam rising to the steady-speed stage is flushed, or that a large amount of foam is generated in the stage before flushing as much as possible when foam flushing is not performed in the drainage stage, ensuring the completion of foam elimination.
In a corresponding embodiment, the first dewatering and defoaming process is more specific and can be that of dewateringAfter the start, acquiring the instant dehydration rotating speed R; judging whether the instant dewatering rotating speed R is equal to the first flushing rotating speed R 1 The method comprises the steps of carrying out a first treatment on the surface of the When the instant rotation speed R of dehydration is equal to R 1 Foam flushing is performed at this time, wherein a first flushing rotational speed R 1 Less than or equal to the dehydration target rotation speed R max Target rotation speed R of dehydration max For the target rotation speed of the dehydration step input/selected by the user, similarly, the condition judgment of the second dehydration and defoaming process is similar, but the interval quantity of the speed of the steady speed stage has no great influence on the effect of the first dehydration and defoaming process, so the first washing rotation speed R 1 Dehydration target rotation speed R less than or equal to max Can be used, and R is 1 ＝R max The time point is closer to the t1 time point, the flushing effect is better, and of course, the same R 1 ＝aR max A is a constant of 0 < a.ltoreq.1, and can be measured experimentally.
In a corresponding embodiment, the foam rinse comprises: preset time T 0 After opening the flushing valve, flushing time K 0 The flushing valve is completely closed afterwards; can set T 0 =5 seconds, K 0 =10 seconds, i.e. after the condition is reached, after 5 seconds, the flush valve is opened, the foam is flushed, then after 10 seconds the flush valve is closed; of course, T can also be set 0 =0 seconds, K 0 =7 seconds, i.e. the condition is reached without a buffer time to open the flush valve, 7 seconds later to close the flush valve; it should be noted that the foam wash does not affect the whole set/selected washing process, in particular time, drainage, speed variation.
In a corresponding embodiment, the flushing of the flushing foam is a continuous flushing, i.e. a flushing time K, or a discontinuous flushing 0 The inner flush valve remains open; intermittent flushing, i.e. flushing time K 0 The internal flushing valve is switched multiple times and a normally used solenoid valve can be pulsed to form intermittent flushing, e.g. K 0 The flush valve was opened for 2 seconds, closed for 1 second, and formed intermittent 5 openings, 4 for enhanced flushing.
Specifically, the defoaming method logic is described below with reference to fig. 3, 4, and 5, and is described with reference to fig. 1, 6, 7, and 8.

Although embodiments of the present invention have been disclosed above, it is not limited to the use of the description and embodiments, it is well suited to various fields of use for the invention, and further modifications may be readily apparent to those skilled in the art, and accordingly, the invention is not limited to the particular details without departing from the general concepts defined in the claims and the equivalents thereof.
The foregoing describes specific embodiments of the present disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims can be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes in the figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented with "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but HDL is not only one, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., VHDL (Very-High-Speed, integrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.
