[0037] In order to enable a person skilled in the art to better understand the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings, which are only used for reference and do not limit the embodiments of the present application.

[0038] The embodiments of the present application provide a washing machine dehydration control method, which is applied to a washing machine dehydration control stage. The washing machine comprises a balance ring, the balance ring is installed around an inner drum wall of the washing machine, and a box is arranged in the balance ring.

[0039] In actual application, at least two boxes are arranged along the annular balance ring, and the at least two boxes are distributed along the annular balance ring at equal intervals or non-equal intervals. Figure 1 As shown in FIG. 1, the balance ring 10 comprises three boxes distributed along the annular balance ring at equal intervals, i.e., a first box 101, a second box 102 and a third box 103.

[0040] The balance ring further comprises an injection channel and an injection outlet. After the control valve is opened, water flows into the box through the injection channel, and the water flows out of the box through the injection outlet.

[0041] Based on this, the embodiments of the present application provide a washing machine dehydration control method, Figure 2 Figure 3 is a first flowchart of a washing machine dehydration control method according to an embodiment of the present application. As shown in FIG. 3, the method comprises the following steps. Figure 2

[0042] Step 201: obtaining a current rotating speed of the washing machine;

[0043] Here, the rotating speed is a working parameter of a driving motor of the washing machine, which can be directly obtained by reading the working parameter of the driving motor.

[0044] Step 202: determining that the current rotating speed is less than or equal to a rotating speed threshold value, obtaining a first preset function, and calculating a first water supplement amount or a first water supplement time according to the first preset function;

[0045] ​Exemplarily, the rotation speed threshold value can be 100 revolutions per minute, 200 revolutions per minute, 300 revolutions per minute, etc. The dehydration control can be divided into a dehydration control in a low-speed stage and a dehydration control in a high-speed stage by the rotation speed threshold value. The water replenishment time and the water replenishment amount can be accurately controlled when the water replenishment is performed in different rotation speed stages, the situation that the amplitude is increased due to excessive water replenishment is avoided, and the water replenishment frequency is increased due to insufficient water replenishment, and the eccentricity compensation efficiency is improved.

[0046] The first preset function is a function related to the actual vibration amplitude, and is used to represent the influence of the actual vibration amplitude on the water replenishment amount or the water replenishment time. The vibration amplitude is referred to as amplitude.

[0047] Exemplarily, the first preset function is obtained by: obtaining a plurality of sets of calibration data of vibration amplitudes of the washing machine, the calibration data including actual vibration amplitudes of the washing machine; and performing a fitting function curve according to the plurality of sets of calibration data to obtain the first preset function.

[0048] The plurality of sets of calibration data are a plurality of sets of actual vibration amplitudes obtained at the current rotation speed stage. For example, the actual vibration amplitudes are 2 mm, 3 mm, 4 mm, 5 mm, etc. The fitting function curve is performed according to the plurality of sets of calibration parameters to determine the known quantities in the first preset function.

[0049] Specifically, the expression of the first preset function is y1=f(dis1), where y1 is the water replenishment time or the water replenishment amount, dis1 is the actual vibration amplitude, and y1 and dis1 are unknown quantities in the function. The current actual vibration amplitude is substituted into the first preset function to calculate y1. The first preset function can represent that the water replenishment time or the water replenishment amount increases with the increase of the actual vibration amplitude, and the relationship therebetween can be a linear corresponding relationship, a nonlinear corresponding relationship, or a stepped corresponding relationship.

[0050] Exemplarily, in some embodiments, the fitting function curve is performed according to the plurality of sets of calibration data, including: fitting an actual vibration amplitude and a preset vibration amplitude related function curve to obtain the first preset function. Here, the preset vibration amplitude is a maximum vibration amplitude allowed by the washing machine in the normal working state at the current rotation speed stage, and the water replenishment operation needs to be performed to reduce the vibration when the maximum vibration amplitude is exceeded.

[0051] Specifically, the expression of the first preset function is y1=f(dis1,dis2), where y1 is the water replenishment time or the water replenishment amount, dis1 is the actual vibration amplitude, and dis2 is the preset vibration amplitude.

[0052] For example, a running program of the first preset function is generated, and the current actual vibration amplitude is taken as an input variable. The running program obtains the water replenishment time or the water replenishment amount. Alternatively, a discrete mapping relationship table is established in advance according to the first preset function, and the current actual vibration amplitude is used to query the mapping relationship table to obtain the water replenishment time or the water replenishment amount.

[0053] For example, in some embodiments, the method further includes: obtaining a current actual vibration amplitude of the washing machine, the current actual vibration amplitude being greater than the preset vibration amplitude, and obtaining the first preset function.

[0054] For example, the washing machine inner drum wall is provided with at least one vibration detection device, and vibration information of the vibration detection device is controlled. The current actual amplitude is obtained by data processing of the vibration information. For example, the vibration detection device can be a displacement sensor, an acceleration sensor, or a Hall sensor.

[0055] For example, in some embodiments, the method further includes: obtaining the current actual vibration amplitude and the preset vibration amplitude; and determining that the current vibration amplitude is less than or equal to the preset vibration amplitude, and then ending the current speed step and entering a next speed step.

[0056] For example, as shown in Figure 3 two speed steps are set. The first speed step has a speed range of 0-100 revolutions per minute (inclusive), which is defined as a low-speed stage. The second speed step has a speed range of 100 (exclusive) to an upper limit of the speed, which is defined as a high-speed stage.

[0057] The preset amplitudes corresponding to each speed step are equal or unequal. For example, the preset amplitude corresponding to the first speed step is 5 mm, and the preset amplitude corresponding to the second speed step is 3 mm.

[0058] For example, as shown in Figure 4 In some embodiments, four speed steps are set in the dehydration process. The first speed step has a speed range of 0-100 revolutions per minute, the second speed step has a speed range of 100-200 revolutions per minute, the first speed step and the second speed step are defined as a low-speed stage, the third speed step has a speed range of 200-400 revolutions per minute, the fourth speed step has a speed range of 400- an upper limit of the speed, and the third speed step and the fourth speed step are defined as a high-speed stage.

[0059] For example, the preset amplitude corresponding to the first speed step is 5 mm, the preset amplitude corresponding to the second speed step is 4 mm, the preset amplitude corresponding to the third speed step is 3 mm, and the preset amplitude corresponding to the fourth speed step is 2 mm. It can be understood that five speed steps or more speed steps can also be set.

[0060] The division of the rotating speed step and the setting of the preset amplitude are only exemplary and are not limited. In actual applications, the division of the rotating speed step and the setting of the preset amplitude can be flexibly set according to the structure and anti-vibration capability of the washing machine.

[0061] Step 203: according to the first water supplement amount or the first water supplement time, water is injected into the box.

[0062] Specifically, the control valve is opened according to the first water supplement amount or the first water supplement time, and water is supplemented to the box in the balance ring until the amplitude is less than or equal to the preset amplitude.

[0063] By using the above technical solution, in the dehydration stage, the first preset function related to the current vibration amplitude is used to determine the matched water supplement amount and water supplement time, so as to accurately control the water injection operation to the box, effectively perform eccentric compensation, and improve the dehydration efficiency of the washing machine. The problem that the compensation time is too long or the compensation fails due to improper setting of the water supplement parameters of the existing washing machine is solved.

[0064] On the basis of the above method embodiment, the washing machine dehydration control is further exemplified.

[0065] As shown in the method, the method can specifically include: Figure 5

[0066] Step 501: the current rotating speed of the washing machine is obtained;

[0067] Step 502: it is determined that the current rotating speed is less than or equal to the rotating speed threshold;

[0068] Step 503: the current actual vibration amplitude and the preset vibration amplitude of the washing machine are obtained;

[0069] Step 504: the ratio of the current actual vibration amplitude to the preset vibration amplitude is calculated, wherein the current actual vibration amplitude is dis1, the preset vibration amplitude is dis2, the ratio is n, and n = dis1 / dis2;

[0070] Step 505: it is determined whether n is greater than 2, if n>2, a first preset function is obtained;

[0071] That is, when the current rotating speed is less than the rotating speed threshold and the ratio of the current actual vibration amplitude to the preset vibration amplitude is greater than 2, the first water supplement amount or the first water supplement time is calculated based on the first preset function.

[0072] Exemplarily, in some embodiments, if n≤2, water is supplemented into the box for a first duration. The first duration can be 1s, 1.5s, or 2s. That is, when the current rotating speed is less than the rotating speed threshold, but the ratio of the current actual vibration amplitude to the preset vibration amplitude is less than or equal to 2, water is supplemented into the box at a preset fixed water supplement time or a fixed water supplement amount.​

[0073] Step 506: calculating the first water replenishment amount or the first water replenishment time according to the first preset function;

[0074] For example, the first preset function is obtained by: obtaining the calibration data of the washing machine and the preset vibration amplitude, the calibration data including the actual vibration amplitude of the washing machine; calculating the ratio of the difference between the actual vibration amplitude and the preset vibration amplitude to the actual vibration amplitude; and fitting a function curve of the change of the product of the ratio and n to obtain the first preset function.

[0075] The expression of the first preset function is: y1 = ((dis1-dis2) / dis1) x n, wherein y1 is the water replenishment amount or the water replenishment time, dis1 is the current amplitude, and dis2 is the preset amplitude.

[0076] For example, n can be the actual ratio, or the first or second digit after the decimal point. For example, when the current amplitude is greater than 5 times the preset amplitude, n = 5; when the current amplitude is greater than 4 times the preset amplitude, n = 4; when the current amplitude is greater than 3 times the preset amplitude, n = 3; and when the current amplitude is greater than 2 times the preset amplitude, n = 2.

[0077] In some embodiments, when n > 2, the first preset function is obtained by: obtaining the calibration data of the washing machine and the preset vibration amplitude, the calibration data including the actual vibration amplitude of the washing machine; calculating the ratio of the difference between the actual vibration amplitude and the preset vibration amplitude to the actual vibration amplitude; and fitting a function curve of the change of the product of the ratio and m to obtain the first preset function.

[0078] Here, m is determined according to n. For example, when the current amplitude is greater than 5 times the preset amplitude, i.e., m > 5n, then m = 5s; when the current amplitude is less than or equal to 5 times the preset amplitude and greater than 3 times the preset amplitude, i.e., 3n < m ≤ 5n, then m = 3s; and when the current amplitude is less than or equal to 3 times the preset amplitude and less than 2 times the preset amplitude, i.e., 2n < m ≤ 3n, then m = 2s.

[0079] For example, the first preset function can also be: y1 = ((dis1-dis2) / dis2) x n.

[0080] Step 507: injecting water into the box according to the first water replenishment amount or the first water replenishment time.

[0081] According to the above technical solution, the water replenishment amount and the water replenishment time are not only related to the current vibration amplitude, but also related to the ratio of the current vibration amplitude to the preset vibration amplitude, so that the determination of the water replenishment amount and the water replenishment time is more accurate, and the accuracy of the eccentric compensation of the washing machine is further improved.

[0082] On the basis of the above method embodiments, the spin-drying control of the washing machine is further illustrated.

[0083] As shown in the method, the method can specifically include the following steps. Figure 6

[0084] Step 601: acquiring a current rotating speed of the washing machine.

[0085] Step 602: determining whether the current rotating speed is less than or equal to a rotating speed threshold value; if yes, performing step 603; if no, performing step 605.

[0086] Step 603: acquiring a first preset function, and calculating a first water supplement amount or a first water supplement time according to the first preset function.

[0087] Step 604: supplementing water into the cabinet according to the first water supplement amount or the first water supplement time.

[0088] Step 605: determining that the current rotating speed is greater than the rotating speed threshold value.

[0089] Step 606: acquiring a second preset function, and calculating a second water supplement amount and a second water supplement time according to the second preset function.

[0090] The second preset function is a function related to an actual vibration amplitude, and is used to represent the influence of the actual vibration amplitude on the water supplement amount or the water supplement time in the high-speed stage.

[0091] For example, in some embodiments, the determination that the current rotating speed is greater than the rotating speed threshold value and the acquisition of the second preset function include: acquiring a plurality of sets of calibration data of vibration amplitudes of the washing machine in the high-speed stage, the calibration data including an actual vibration amplitude of the washing machine in the high-speed stage; and according to the plurality of sets of calibration data, fitting a function curve to obtain the second preset function.

[0092] Specifically, the expression of the second preset function is y2=f(dis1), where y2 is the water supplement time or the water supplement amount, and dis1 is the actual vibration amplitude. The second preset function is different from the first preset function.

[0093] For example, the acquisition of the second preset function includes: acquiring a current actual vibration amplitude and a preset vibration amplitude; determining that the current vibration amplitude is greater than the preset vibration amplitude; and determining that the second preset function is a product change of a difference between the current actual vibration amplitude and the preset vibration amplitude and the water supplement time n1, where n1 takes a value of 1s-2s. For example, n1 is 1s, 1.2s, 1.5s or 2s.

[0094] Specifically, the expression of the second preset function is y2=(dis1-dis2)×n1, where y2 is the water supplement amount or the water supplement time, dis1 is the current amplitude, and dis2 is the preset amplitude. ​

[0095] During the dehydration stage, different functions are set for different rotational speed steps to characterize the relationship between the current amplitude and the water replenishment parameters. In the low-speed stage, the first water replenishment amount or the first water replenishment time is calculated according to the first preset function, and in the high-speed stage, the second water replenishment amount or the second water replenishment time is calculated according to the second preset function.

[0096] Step 607: Add water to the tank according to the second water replenishment amount or the second water replenishment time.

[0097] For example, in some embodiments, when the current rotation speed is greater than the rotation speed threshold, the second water replenishment amount is a preset water replenishment amount v1mL, or the second water replenishment time is a preset water replenishment time n1s.

[0098] By adopting the above technical solution, the washing machine uses a first preset function to determine the amount or time of water replenishment during the low-speed spin-drying stage, and a second preset function to determine the amount or time of water replenishment during the high-speed spin-drying stage. This accurately controls the water injection operation into the drum, effectively compensates for eccentricity, and improves the spin-drying efficiency of the washing machine. This solves the problem of excessively long compensation times or compensation failures caused by improper water replenishment parameter settings in existing washing machines.

[0099] Based on the above method embodiments, the washing machine spin-drying control method will be further illustrated with examples. For instance... Figure 7 As shown, the method may specifically include:

[0100] Step 701: Proceed to the dehydration stage;

[0101] Step 702: Rotation speed <= 100? If yes, proceed to step 703; if no, proceed to step 712.

[0102] Step 703: Obtain the current amplitude dis1 and preset the amplitude dis2;

[0103] Step 704: dis1>(5×dis2)? If yes, proceed to step 705; if no, proceed to step 706.

[0104] Step 705: t1 = ((dis1 - dis2) / dis1) × 5s;

[0105] Here, the first preset function is t1 = ((dis1 - dis2) / dis1) × n, n = 5s;

[0106] Step 706: dis1>(3×dis2)? If yes, proceed to step 707; if no, proceed to step 708.

[0107] Step 707: t1 = ((dis1 - dis2) / dis1) × 3s;

[0108] Here, n = 3s;

[0109] Step 708: t1 = 2s;

[0110] Here, when (3 x dis2) ≥ dis1 > dis2, the water replenishment time is the preset time, i.e., t1 = 2s.

[0111] Step 709: performing single water replenishment operation according to the water replenishment time t1;

[0112] Step 710: dis1 ≤ dis2? If yes, executing step 711; if no, returning to step 703;

[0113] Step 711: increasing from the current rotation speed step to the next rotation speed step;

[0114] Step 712: obtaining the current amplitude dis1 and the preset amplitude dis2;

[0115] Step 713: dis1 > dis2? If yes, executing step 714; if no, executing step 711;

[0116] Step 714: t2 = (dis1-dis2) x 1.2s;

[0117] Here, the second preset function is t2 = (dis1-dis2) x n, n = 1.2s;

[0118] Step 715: performing single water replenishment operation according to the water replenishment time t2, and returning to step 712 after the execution.

[0119] According to different vibration characteristics at different rotation speed steps, the water replenishment is performed, the washing machine vibrates more at low rotation speed and vibrates less at high rotation speed, the water replenishment time is calculated according to the first preset function when the rotation speed is less than 100 revolutions, so as to accurately control the water replenishment time each time; when the rotation speed is greater than 100 revolutions, the water replenishment time is calculated according to the second preset function, or the water replenishment time is a fixed value, thereby improving the accuracy of water replenishment at different rotation speeds.
