[0002] The dehydration method of current washing machines on the market is to control the washing drum to spin at high speed after the dehydration is completed, using centrifugal force to dehydrate. After washing, the laundry in the washing machine tends to clump to one side, causing eccentricity. The high-speed dehydration produces large vibrations, causing the washing drum to collide with the washing machine shell, resulting in noise.

[0051] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0053] Figure 1 This is a flow chart of a dehydration control method for a washing machine provided by an embodiment of the present disclosure. The dehydration control method for a washing machine can be applied in scenarios where a user needs to use a pulsator washing machine to dehydrate clothes, and can be executed by a dehydration control device for a washing machine provided by an embodiment of the present disclosure. The dehydration control device for a washing machine can be implemented in software and / or hardware. Figure 1 As shown, the dehydration control method of the washing machine includes:

[0054] S101, controlling the washing machine to retain some water for drainage.

[0055] Figure 2 This is a schematic diagram of a timing control for an existing feasible washing machine dehydration control. Figure 2 The horizontal axis is time, the unit is minute (min), and the vertical axis is the speed of the washing machine drum, the unit is revolutions per minute (r / min, rpm). Figure 2 As shown, after the washing machine finishes washing clothes, it will drain all the water in the washing drum. Since the washing machine will pass through the resonance area two to three times during the dehydration process, when passing through the resonance area, the higher the eccentricity of the washing machine and the higher the amount of clothing in the washing drum tilts to one side, the greater the vibration of the resonance area. When the vibration reaches a certain value, the washing drum will collide with the outer shell of the washing machine, causing the washing machine to move or generate noise.

[0056] Therefore, refer to Figure 2 After draining, the washing drum will first rotate at a low speed, and the eccentricity of the washing machine will be measured at this time. When the eccentricity is greater than the preset threshold, it is determined that the washing machine cannot perform high-speed dehydration. At this time, the washing drum will stop rotating and refill water. After refilling water, the washing wings will rotate. The washing wings will evenly spread the washed clothes in the presence of water. Figure 2 In the dispersion process, after multiple dispersion processes ( Figure 2The washing machine drains the water again, rotates the washing drum at a low speed and measures the eccentricity again. When the eccentricity is less than the preset threshold, it indicates that the laundry has been evenly dispersed in the washing drum, and dehydration will not cause the aforementioned collision noise problem. At this time, the washing machine is controlled to perform high-speed dehydration. However, this control method for the washing machine will cycle through water replenishment and drainage for multiple times until the eccentricity drops to a certain value and then starts high-speed dehydration, which will result in high water consumption and prolonged washing time.

[0057] The embodiment of the present disclosure does not completely drain the water from the washing drum when the washing is completed and the water is drained. Instead, some water remains in the washing drum after the washing and draining. Therefore, when the eccentricity of the clothes in the washing machine is too large, there is no need to repeatedly add water to allow the washing wings to evenly spread out the clothes to be dehydrated. In addition, when the eccentricity of the clothes in the washing machine is too large, when the washing drum rotates, some of the water retained in the washing drum will move in the opposite direction of the washing clothes due to inertia, thereby improving the eccentricity of the clothes in the washing machine, and further reducing the amount of vibration passing through the resonance area.

[0058] Optionally, controlling the washing machine to retain some water for drainage includes: obtaining the weight of the clothes to be dehydrated in the washing machine; adjusting the amount of water retained in the washing machine for drainage based on the weight of the clothes in the washing machine; wherein the volume of the retained water is proportional to the weight of the clothes.

[0059] Specifically, the weight of the laundry to be dehydrated in the washing tub is first determined. Based on this weight, the volume of water retained in the washing machine is adjusted. The volume of water retained increases with the weight of the laundry to be dehydrated. For example, a water level detection device can be used to detect the amount of water in the washing tub during drainage. When the water level reaches a preset level, drainage is stopped. For example, when the weight of the laundry to be dehydrated is 5 kilograms, the volume of water retained can be 2 liters, and when the weight of the laundry to be dehydrated is 8 kilograms, the volume of water retained can be 4 liters. This change in the volume of water retained in response to the weight of the laundry can improve the degree of eccentricity of the water, reduce resistance when the washing wings spin the laundry, and improve the efficiency of laundry dispersion.

[0060] It should be noted that the specific values ​​and corresponding relationship between the weight of the clothes to be dehydrated and the volume of the retained water can be set according to the actual use of the washing machine, and the embodiments of the present disclosure are not limited here.

[0061] S102: cyclically executing the preset control process until the eccentricity of the laundry to be dehydrated in the washing machine is less than the preset eccentricity.

[0062] Among them, the preset control process includes: obtaining the eccentricity of the clothes to be dehydrated in the washing machine in the preset stage; wherein the rotation speed in the preset stage is less than the rotation speed when the washing machine dehydrates the clothes; based on the eccentricity of the clothes to be dehydrated in the washing machine in the preset stage, the clothes in the washing machine are shaken out.

[0063] Specifically, when some water is retained in the washing drum, the washing machine is controlled to rotate at a low speed, and the rotation speed of the washing machine is lower than the rotation speed when the washing machine dehydrates the clothes, and the eccentricity of the clothes to be dehydrated is obtained in the process. When the eccentricity is greater than the preset eccentricity, it means that the uniformity of the unfolding of the clothes to be dehydrated is low at this time. When the high-speed dehydration passes through the resonance area, the inner drum of the washing machine will collide with the outer shell of the washing machine. At this time, the washing drum can be controlled to stop rotating. Since some water has been retained in the washing drum, there is no need to refill water. The washing wings can be rotated directly in the water state to shake out the clothes to be dehydrated, that is, to disperse the clothes.

[0064] When the washing machine is shaking out the clothes, it can be done by combining forward rotation with reverse rotation. For example, the washing machine can be controlled to rotate forward at a certain acceleration for a certain time, then stop, and then reverse at a certain acceleration for a certain time. It can also be done by shaking out the clothes at a constant speed, that is, rotating the washing drum at a constant speed for a period of time to disperse the clothes. It can also be done by Figure 2 The clothes are spread evenly in the variable speed shaking method shown in the figure. For example, the speed of the washing drum is first increased, then reduced to a certain value, and then increased again, and the speed is repeated multiple times to achieve uniform spreading of the clothes to be dehydrated. The number of cycles of executing the preset control process can be at least one, ensuring that the eccentricity of the clothes to be dehydrated in the washing machine is less than the preset eccentricity and the washing machine can perform a normal high-speed dehydration process.

[0065] It should be noted that other methods can also be used to shake out the clothes to be dehydrated, as long as they can achieve uniform spreading of the clothes and reduce the eccentricity of the clothes. The embodiments disclosed herein are not limited thereto. Any shaking method can also be used to disperse the clothes in the following embodiments, and will not be described in detail later.

[0066] Optionally, obtaining the eccentricity of the clothes in the washing machine in a preset stage includes: controlling the washing machine to increase the rotation speed to a preset rotation speed in the first stage and obtaining the first-stage eccentricity of the clothes in the washing machine in the first stage; controlling the washing machine to maintain the preset rotation speed in the second stage and obtaining the second-stage eccentricity of the clothes in the washing machine in the second stage; wherein, the preset stage includes the first stage and the second stage; controlling the clothes in the washing machine to be shaken out based on the eccentricity of the clothes in the washing machine in the preset stage, including: controlling the clothes to be dehydrated in the washing machine to be shaken out based on the eccentricity of the first stage and the eccentricity of the second stage; wherein, when it is judged that the eccentricity of the first stage and / or the eccentricity of the second stage is greater than the preset eccentricity, controlling the clothes to be dehydrated in the washing machine to be shaken out.

[0067] Figure 3 This is a schematic diagram of a timing control of a washing machine dehydration control provided by an embodiment of the present disclosure. Specifically, Figure 3 The horizontal axis is time, the unit is minute (min), and the vertical axis is the speed of the washing machine drum, the unit is revolutions per minute (r / min, rpm). Figure 3 As shown, after the washing machine finishes washing, some water is retained and drained before entering the first stage. The first stage can be a stage in which the washing machine accelerates to rotate. For example, the preset speed can be set to Figure 3 As shown in FIG, the speed of the washing machine in the first stage is increased from 0 rpm to 120 rpm. During the accelerated rotation of the washing machine, the eccentricity of the clothes to be dehydrated in the first stage, i.e., the eccentricity of the first stage UB1, is detected. After the washing machine is controlled to speed up to the preset speed in the first stage, the washing machine is controlled to rotate at a uniform speed in the second stage of the preset stage. For example, the washing machine is controlled to maintain the speed at 120 rpm. During the uniform rotation of the washing machine, the eccentricity of the clothes to be dehydrated in the second stage is detected. For example, Figure 3 For example, when the washing machine is controlled to rotate at a constant speed for 10 seconds, the eccentricity UB2 in the first 5 seconds and the eccentricity UB3 in the last 5 seconds of the constant speed rotation stage can be detected respectively.

[0068] Specifically, after the acceleration and uniform speed control process of the aforementioned washing machine is completed, the eccentricity in the first stage is compared with a preset eccentricity. If the eccentricity in the first stage is greater than the preset eccentricity, the speed of the washing machine is controlled to decrease after the second stage, for example, to zero, and the clothes to be dehydrated in the washing machine are shaken out. If the eccentricity in the second stage, i.e., UB2 or UB3, exceeds the preset eccentricity, the speed of the washing machine is controlled to decrease after the second stage, for example, to zero, and the clothes to be dehydrated in the washing machine are shaken out. Figure 3 FIG. 5 exemplarily shows that the clothes are dispersed twice, and the specific number of times of dispersing the clothes is not limited in the embodiment of the present disclosure.

[0069] It should be noted that, as a preferred embodiment, after detecting the eccentricity of the clothes in the first stage and the second stage, the eccentricity of the clothes in the two stages can be compared with the preset eccentricity. When any one of the eccentricity of the first stage and the eccentricity of the second stage exceeds the preset eccentricity, the washing machine is triggered to shake out the clothes to be dehydrated. The shaking action of the washing machine is triggered after the eccentricity of the two stages is comprehensively considered, which can effectively improve the accuracy of controlling the shaking action. The specific time length can be set according to the actual use of the washing machine, and the embodiment of the present disclosure does not limit this. For example, it can also be set that when the time when the eccentricity of the first stage exceeds the preset eccentricity exceeds the first preset time, and / or the time when the eccentricity of the second stage exceeds the preset eccentricity exceeds the second preset time, the clothes in the washing machine are controlled to be shaken out, so as to further improve the accuracy of controlling the shaking action.

[0070] In addition, it is also possible to detect the eccentricity only in the first stage and then compare it with the preset eccentricity. After exceeding the preset eccentricity, the clothes to be dehydrated in the washing machine will be shaken out. It is also possible to detect the eccentricity only in the second stage and then compare it with the preset eccentricity. After exceeding the preset eccentricity, the clothes to be dehydrated in the washing machine will be controlled to be shaken out. It is possible to control the washing machine to shake out the clothes to be dehydrated according to the eccentricity of the clothes to be dehydrated in the washing machine in the preset stage, and the embodiments of the present disclosure are not limited to this.

[0071] Optionally, obtaining the eccentricity of the clothes in the washing machine at a preset stage includes: detecting the effective driving current of the motor in the washing machine at the preset stage; controlling the clothes in the washing machine to be shaken out based on the eccentricity of the clothes in the washing machine at the preset stage, including: controlling the clothes in the washing machine to be shaken out based on the effective driving current; wherein, when it is determined that the effective driving current exceeds the preset effective driving current, controlling the clothes in the washing machine to be shaken out.

[0072] Specifically, a correspondence between the weight of the laundry and a preset effective drive current, i.e., the current value required by the washing machine to loosen the laundry, can be pre-stored. The preset effective drive current can increase as the pre-stored laundry weight increases. During the dehydration process, after detecting the effective drive current of the washing machine's motor at a preset stage, the corresponding pre-stored preset effective current value is queried and compared. If the effective drive current exceeds the preset effective drive current, it indicates that the eccentricity has exceeded the normal value. The washing machine is then controlled to loosen the laundry before high-speed dehydration.

[0073] For example, it can be pre-stored that when the weight of the clothes to be dehydrated is 2 kg, the corresponding preset effective driving current is 0.5 A. When 2 kg of clothes need to be dehydrated during the actual washing process, the effective driving current of the motor in the washing machine in the preset stage is obtained, for example, 1 A, which means that the effective driving current at this time exceeds the preset effective current, and the clothes in the washing machine are controlled to be shaken apart; when the weight of the clothes to be dehydrated is 2 kg, the effective driving current of the motor in the washing machine in the preset stage is obtained, for example, 0.4 A, which means that the effective driving current at this time does not exceed the preset effective driving current, and the eccentricity of the clothes meets the conditions for high-speed dehydration of the washing machine. When passing through the resonance area, it will not cause the washing drum to collide with the washing machine shell, and the washing machine can be controlled to perform high-speed dehydration.

[0074] It should be noted that the specific values ​​and corresponding relationship between the preset effective driving current and the weight of clothes can be set according to the actual use of the washing machine, and the embodiments of the present disclosure are not limited to this.

[0075] Optionally, before shaking out the clothes in the washing machine based on the effective driving current control, the method further includes: obtaining the weight of the clothes in the washing machine; and dynamically obtaining a preset effective driving current based on the weight of the clothes.

[0076] Specifically, since the preset effective driving current will change with the change of the weight of the clothes, for example, the heavier the clothes, the greater the effective driving current, the preset effective driving current is a variable value. During the dehydration process of the washing machine, the weight of the clothes to be dehydrated is first detected. For example, a gravity sensing element such as a scale is installed in the washing machine to obtain the weight of the clothes to be dehydrated, and then the preset effective driving current under the corresponding weight is obtained based on the weight of the clothes to be dehydrated in the washing drum. For example, when the scale detects that the weight of the clothes is 2 kilograms, the preset effective driving current is, for example, 0.4 amps. When the scale detects that the weight of the clothes is 5 kilograms, the preset effective driving current is, for example, 0.5 amps. When dehydrating clothes of different weights, different preset effective driving currents are obtained. In addition, a control panel can also be provided on the washing machine, and the user can directly input the weight of the clothes to be dehydrated before dehydration. The embodiments of the present disclosure are not limited to this. Therefore, by detecting the weight of the clothes and dynamically obtaining different preset effective currents, it can be ensured that the preset effective current can change with the change of the weight of the clothes, avoiding the influence of a single preset effective driving current on the judgment of the eccentricity of clothes of different weights, and improving the accuracy of the eccentricity detection of the washing machine.

[0077] Optionally, the clothes in the washing machine are shaken out based on the eccentricity of the clothes in the washing machine in a preset stage, including: controlling the shaking intensity of the clothes to be dehydrated in the washing machine based on the eccentricity of the clothes to be dehydrated in the washing machine in a preset stage; wherein the shaking intensity increases with the increase of the eccentricity.

[0078] Specifically, the shaking intensity of the washing machine can be set to increase with the increase of the eccentricity. For example, when the eccentricity increases, the shaking times of the washing machine can be controlled to increase. For example, when the eccentricity increases from 20 to 50, the constant speed shaking times of the washing machine can be controlled to increase from 2 times to 5 times; in addition, when the eccentricity increases, the forward and reverse time and number of times the washing machine is shaken can also be controlled to increase accordingly. For example, when the eccentricity is 20, the washing machine is controlled to rotate forward at maximum acceleration for 30 seconds and then reverse at maximum acceleration for 30 seconds, and shake the clothes after reversing twice according to this forward and reverse strategy; when the eccentricity increases to 50, the washing machine is controlled to rotate forward at maximum acceleration for 1 minute and then reverse at maximum acceleration for 1 minute, and shake the clothes after reversing 3 times according to this forward and reverse strategy; the washing machine can also be controlled to do the following Figure 3 The speed change jitter shown in the figure can also increase with the increase of the eccentricity. For example, when the eccentricity increases from 20 to 50, the speed change jitter increases from 2 times to 5 times. The specific process of speed change jitter can be implemented with reference to the above embodiment, and the embodiment of the present disclosure will not be described in detail here.

[0079] It should be noted that the specific value of the shaking intensity and the corresponding relationship between the shaking intensity and the eccentricity can be set according to the usage of the washing machine, and the embodiments of the present disclosure are not limited to this.

[0080] S103: Control the washing machine to dehydrate the clothes.

[0081] Specifically, when the eccentricity detection value meets the dehydration requirements, the washing machine is controlled to dehydrate the clothes at a high speed, with the dehydration speed being higher than the preset speed when the eccentricity is detected. For example, if the preset speed is 150 rpm, the dehydration speed can be used to continue for 5 minutes at 500 rpm until the clothes are completely dehydrated. It should be noted that the dehydration parameters can be set according to the actual use requirements of the washing machine and are not limited in this embodiment of the present disclosure.

[0082] Optionally, before controlling the washing machine to dehydrate the clothes, it also includes: obtaining the number of cycle executions of a preset control process; when the number of cycle executions exceeds the preset number of cycle executions, controlling the washing machine to stop and / or controlling the washing machine to issue a warning message of dehydration abnormality.

[0083] Specifically, it can also be set to obtain a preset number of cycles of the preset control process before the washing machine dehydrates. For example, when the preset number of cycles is 5 times, and the actual number of cycles has reached 6 times, it means that the efficiency of the washing machine for distributing the clothes is low at this time. The washing machine can be controlled to stop and no longer execute the preset control process. At this time, the user can take out the clothes, shake the clothes manually, and put the clothes back into the washing drum after they are evenly shaken. The washing machine re-executes the dehydration control method of the washing machine provided in the embodiment of the present disclosure.

[0084] In addition, the washing machine can also issue a warning message of dehydration abnormality. For example, a display prompt device can be set on the washing machine. The display prompt device can be, for example, an LED signal light. When the number of cycle executions exceeds the preset number of cycle executions, the LED signal light is controlled to emit a warning signal such as a continuous light or a flashing light. In addition, the display prompt device can also be a display screen to display the corresponding text prompt information of the dehydration abnormality. The embodiments of the present disclosure are not limited to this.

[0085] In addition, a sound prompt device may be provided on the washing machine. When the number of cycles exceeds a preset number, the sound prompt device may play "Dehydration abnormality, please turn off the washing machine" or other prompts with similar meanings. The sound prompt device may also be a device that can emit a sound prompt, such as a buzzer. When a dehydration abnormality occurs, the buzzer may emit a long beep or an intermittent beep, etc. This embodiment of the present disclosure is not limited to this.

[0086] It should be noted that when the number of cycle executions exceeds the preset number of cycle executions, the washing machine can be set to stop running and the washing machine can be controlled to issue an abnormal dehydration warning message, or the washing machine can be set to only stop running, or the washing machine can be set to only issue an abnormal dehydration warning message.

[0087] The embodiment of the present disclosure provides a dehydration control method for a washing machine, which retains some water during drainage, and cyclically executes preset control stages until the eccentricity of the clothes in the washing machine reaches the preset eccentricity, and then dehydrates the clothes. The retained water makes it unnecessary to replenish water and drain water again when the eccentricity of the clothes in the washing machine is greater than the preset eccentricity in the preset stage. The washing machine can spread the clothes evenly, reducing the water consumption and dehydration time of the dehydration process. When the clothes have a large eccentricity, the reverse movement of the retained water can be used to reduce the vibration amount in the resonance area during the dehydration stage, improve the eccentricity of the clothes in the washing machine, and avoid the collision between the washing drum and the washing machine shell to generate noise.

[0088] The embodiment of the present disclosure also provides a dehydration control device for a washing machine. Figure 4 This is a structural diagram of a dehydration control device for a washing machine provided by an embodiment of the present disclosure, as shown in FIG. Figure 4As shown, the dehydration control device of the washing machine includes a drainage control module 501, a circulation execution module 502 and a dehydration control module 503, wherein the drainage control module 501 is used to control the washing machine to retain part of the water for drainage; the circulation execution module 502 is used to cyclically execute the preset control process until the eccentricity of the clothes in the washing machine is less than the preset eccentricity; the dehydration control module 503 is used to control the washing machine to dehydrate the clothes; wherein, the preset control process includes: obtaining the eccentricity of the clothes in the washing machine at a preset stage; wherein, the rotation speed at the preset stage is less than the rotation speed when the washing machine dehydrates the clothes; and controlling the clothes in the washing machine to be shaken out according to the eccentricity of the clothes in the washing machine at the preset stage.

[0089] Optionally, the drainage control module 501 is specifically used to: obtain the weight of the clothes in the washing machine; control the washing machine to retain some water for drainage according to the weight of the clothes in the washing machine; wherein the volume of the retained water is proportional to the weight of the clothes.

[0090] Specifically, the weight of the laundry to be dehydrated in the washing tub is first determined. Based on this weight, the volume of water retained in the washing machine is adjusted. The volume of water retained increases with the weight of the laundry to be dehydrated. For example, a water level detection device can be used to detect the amount of water in the washing tub during drainage. When the water level reaches a preset level, drainage is stopped. For example, when the weight of the laundry to be dehydrated is 5 kilograms, the volume of water retained can be 2 liters, and when the weight of the laundry to be dehydrated is 8 kilograms, the volume of water retained can be 4 liters. This change in the volume of water retained in response to the weight of the laundry can improve the degree of eccentricity of the water, reduce resistance when the washing wings spin the laundry, and improve the efficiency of laundry dispersion.
