Description

Technical Field

[0001] The present invention relates to the technical field of washing control, and particularly to a washing device and its pre-soaking control method, an electronic device, and a storage medium. Background Art

[0002] In order to achieve better washing effects, make the cleaning more thorough, and reduce the number of washings, etc., some washing devices perform a soaking process on the clothes before the main washing program starts. The soaking process usually involves adding clean water to the washing device, soaking the clothes for a period of time, and performing slight agitation, which can better soften the stains on the clothes.

[0003] During the soaking process, generally a combination of multiple soaking methods with different rotation-stop ratios or multiple soakings with the same rotation-stop ratio is used to fully soak the clothes. In order to reduce the wear on the clothes, the rotation speed during the soaking process needs to be set low. Since the lifting ribs can only play an agitation role at a certain rotation-stop ratio, the effect of agitating the clothes with the lifting ribs is poor at this time, resulting in a poor soaking effect of the clothes and unevenly dissolved stains in the water, thereby affecting the washing ratio of the whole machine and failing to maximize the role of the soaking process.

[0055] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0056] Embodiment 1

[0057] A pre-soaking control method for a washing device, configured to be executed before the main washing program, as Figure 1 shown, includes the following steps:

[0058] S1. Determine whether the currently executing program is a pre-soaking program; the pre-soaking control method provided in this embodiment is applicable to a washing device designed with a pre-soaking program. This type of washing device can separately set pre-soaking related options on the function interface. To save the user's operation time and make more efficient use of the function interface, the pre-soaking function can also be nested in other washing processes. For example, the pre-soaking function can be nested in the heavy wash process.

[0059] In some embodiments, the washing device can be a mini washing device for washing close-fitting clothes, a wall-mounted washing device for washing a small amount of children's clothes, or a medium-large washing device for washing a small amount of precious fabric clothes.

[0060] S2. If it is a pre-soaking program, control the clamping device to perform a clamping action before water inlet;

[0061] In this embodiment, a lifting rib is installed on the inner drum of the washing device, and a clamping device capable of clamping clothes is loaded on the lifting rib. By using the lifting rib to close the jaws of the clamping device, the area of the clamping device in contact with the water environment is reduced, enhancing the waterproof ability. In some embodiments, the clamping device can also be referred to as a picking device or a grasping device or a clamping device, etc. In this embodiment, it can be configured to drive the clamping device to move by a power mechanism, thereby performing a clamping action. When controlling the clamping device to perform a clamping action, the power mechanism drives the corresponding clamping device to extend from the installation opening provided on the surface of the lifting rib until it is clamped, so as to clamp the clothes near the lifting rib, and further provide actions such as pulling, stirring, and shaking of the clothes during the pre-soaking process.

[0062] In this embodiment, the user places the clothes in the inner drum of the washing device. Due to the action of gravity, the clothes are usually in the bottom area of the inner drum. To ensure the clamping accuracy of the clamping device, the inner drum can also be controlled to rotate several times first, and the clothes rotate with the drum and tumble at the bottom of the drum. When the lifting rib loaded with the clamping device drives the clothes to rotate to the bottom area of the drum together, control the clamping device to perform a clamping action. It should be noted that the bottom area of the inner drum does not only refer to the physically lowest point of the inner drum, but refers to the position where the lifting rib rotates to the bottom of the inner drum and can clamp the clothes located at the bottom of the drum. As Figure 6 shown, the clamping device 3 on the lifting rib 2 in the inner drum 1 of the washing device performs a clamping action at the position shown in the figure to achieve clothes clamping.

[0063] Inside the inner drum, the lifting ribs divide the space of the inner drum near them into two parts according to their positions inside the drum, forming spaces on both sides of the lifting ribs. Clamping devices can be arranged on both sides of the lifting ribs. In this embodiment, the specific positions of the clamping devices arranged on the lifting ribs are not limited. When the actual motion conditions of the washing device are different, the clothes can be located on either side of the lifting ribs. Correspondingly, in terms of spatial distribution, the direction in which the clamping devices extend from the open end out of the lifting ribs generally corresponds to the spaces on both sides of the lifting ribs, enabling the clamping of the clothes on both sides of the lifting ribs.

[0064] It should be noted that Figure 6 the clamping device 3 shown on each lifting rib in [reference] is only used to indicate that there is a clamping device on the lifting rib. During actual use, when the clamping device 3 is not clamping clothes, it can be retracted into the lifting rib 2. And it is not limited to having clamping devices on both sides of the lifting ribs. As shown in [reference], there can be a clamping device on one side of the lifting rib, or there can be clamping devices on both sides of the lifting rib. Figure 6 In [reference],

[0065] S3. Control the water inlet valve to open to fill water into the inner drum; in this embodiment, this water inlet can be the first water inlet for performing the pre-soaking program to conduct pre-soaking. Control the water inlet valve to open, and the inner drum starts the first water inlet for pre-soaking. During the water inlet process, the inner drum can be configured to rotate, or it can also be configured to rotate the drum after the water inlet is completed.

[0066] In some embodiments, filling water into the inner drum is not limited to the first time of filling water into the inner drum, and it can also be re-filling water during the pre-soaking program. For example, for washing particularly dirty clothes, after one or several pre-soakings, the sewage can be drained through the drain pump, and then water can be filled again for pre-soaking, etc.; another example is that the user interrupts the current pre-soaking program, selects to execute other programs, and then re-selects the pre-soaking program to execute. At this time, it can continue to execute backward immediately following the progress of the most recent water inlet. The rotation of the inner drum can be controlled during the water inlet process, or the rotation of the drum can be controlled after the water inlet is completed.

[0067] S4. Control the inner drum to rotate, and the clothes move in the water environment of the inner drum under the traction of the clamping devices to agitate the clothes during the pre-soaking process;

[0068] In this embodiment, it can be configured that the inner drum is driven to rotate by the inner drum driving device. Among them, the inner drum driving device includes but is not limited to a belt pulley driven by a motor or a direct drive motor, etc. It should be noted that in order to ensure the clamping effect, protect the internal power supply device of the drum that supplies power to the clamping components in the drum, and minimize the wear on the clothes, here the washing device controls the inner drum driving device to drive the inner drum to rotate at a low speed, that is, the rotation speed at this time is lower than the rotation speed of the inner drum during washing, dehydration, etc.

[0069] After pre-soaking, the clothes are fully soaked by the water in the inner tub and move in the water environment of the inner tub under the traction of the clamping device, so as to stir the clothes during the pre-soaking process, accelerate the dissolution of local dirt, and evenly dissolve the stains on the clothes in the water. For a washing device with a water quality detection function, in conjunction with water quality detection, it can judge the water quality situation, including stain types, dirt levels, etc.

[0070] S5. If it is not the pre-soaking program, continue to execute the current program.

[0071] In some embodiments, the parameters of the subsequent washing process are adjusted according to the water quality parameters after stirring the clothes, making the washing process of the washing device more intelligent. For example Figure 2 as shown, the following steps are further included:

[0072] S6. Obtain water quality parameters; wherein, the water quality parameters include one or more of turbidity, TDS, and TOC.

[0073] In this embodiment, the water quality parameters are collected by a water quality sensor set in the water path. In some embodiments, a turbidity sensor or a TDS sensor can be used to collect the turbidity of the water body or the water hardness to indicate the water quality situation; in other embodiments, a TOC sensor can be used to collect the organic carbon content in the water body to indicate the water quality situation; more preferably, a sensor for the comprehensive water quality index can also be used to indicate the water quality situation.

[0074] S7. Adjust the parameters of the subsequent washing process according to the water quality parameters. Among them, adjusting the parameters of the subsequent washing process includes increasing or decreasing the washing time, rotation speed, rhythm, number of times, etc., and the subsequent washing process includes the main washing process and the rinsing process.

[0075] In this embodiment, after stirring the clothes, the washing parameters in the subsequent washing process are optimized and adjusted according to the dirt level of the clothes, realizing the adjustment and optimization of the washing parameters on the basis of the basic washing degree of the washing device, making the washing process of the washing device more intelligent.

[0076] In some embodiments, adjusting the parameters of the subsequent washing process according to the water quality parameters further includes the following steps:

[0077] Judge whether there are special stains in the water through the water quality parameters; wherein, the special stains include blood stains, milk stains, oil stains, etc. It can be judged whether there are special stains in the water by judging whether one or more of turbidity, TDS, and TOC in the water quality parameters are within the numerical range corresponding to the special stains.

[0078] If there are special stains in the water, adjust the parameters of the subsequent washing process. Among them, adjusting the parameters of the subsequent washing process also includes increasing or decreasing the main washing time, rotation speed, rhythm, number of rinses, rinsing time, etc.

[0079] In some embodiments, before the step of obtaining water quality parameters, the following steps are further included:

[0080] Obtain the number of reciprocating movements of the clamped clothing; in this embodiment, the number of reciprocating movements of the clamped clothing is obtained by the number of reverse rotations of the inner cylinder. When the inner cylinder performs one reverse rotation, the number of reverse rotations is incremented by one.

[0081] If the number of reciprocating movements of the clamped clothing reaches a preset number, obtain the water quality parameters; for example, the stirring action is configured to rotate the inner cylinder at a low speed and reciprocate at the water level of the inner cylinder 3 times. At this time, the number of reverse rotations is 3 times. Then obtain the water quality parameters.

[0082] In this embodiment, it can be experimentally determined in advance how many times the clothing of different materials and weights can move back and forth in the water environment of the inner cylinder under the traction of the clamping device so that the stains on the clothing can be fully and evenly dissolved in the water, and the corresponding number of reverse rotations is preset in the washing device.

[0083] If the number of reciprocating movements of the clamped clothing does not reach the preset number, continue to stir the clothing.

[0084] In some embodiments, by detecting the water quality parameters of the washing water after stirring the clothing in the washing device, and then determining the change of the water quality after the clothing moves in the water environment of the inner cylinder under the traction of the clamping device according to the detection result of the water quality parameters, so as to accurately obtain the soaking effect of the washing device. After the water quality of the soaking water after stirring the clothing reaches the corresponding set working condition, control the clamping device to perform a release action to loosen the clothing and terminate the state of clamping the clothing. There is no need to clamp the clothing all the time. After loosening, the clamping device can be retracted into the lifting rib, which does not affect the subsequent laundry process. Furthermore, it realizes the intelligent control of the end time node of the movement of the clamping device to pull the clothing in the water environment of the inner cylinder according to the detection result of the water quality of the soaking water after stirring the clothing, achieving the precision and intelligence of the pre-soaking process control of the washing device, and effectively preventing the occurrence of situations such as low softening efficiency of stains on the clothing, incomplete soaking of the clothing, and uneven dissolution of stains in the water.

[0085] As Figure 3 shown, the following steps are further included:

[0086] S8. Determine whether the water quality parameters reach a preset value; in this embodiment, it can be configured to detect the water quality parameters by a water quality sensor or the like after the clamping device stirs the clothing, or it can be configured to stir the clothing by the clamping device, then soak for a preset time, and then detect the water quality parameters by a water quality sensor or the like. The turbidity of the washing water in the washing device during the soaking process after stirring the clothing can be detected every unit time interval.

[0087] S9. If the water quality parameter reaches the preset value, control the clamping device to perform a release action to loosen the clamped clothes. By comparing the water quality parameter with the preset value, the soaking effect of the washing device can be accurately obtained. After the water quality of the soaking water after the clothes are agitated reaches the corresponding set working condition, control the clamping device to perform a release action to loosen the clothes, terminate the state of clamping the clothes, and do not affect the subsequent laundry process, making the pre-soaking process control of the washing device precise and intelligent.

[0088] S10. If the water quality parameter does not reach the preset value, determine whether the current change amount / change rate of the water quality parameter is less than the preset increment of the previous change amount / change rate. Among them, the preset increment is obtained according to the dissolution change law of stains on clothes of different materials and weights, and the preset increment is preset in the washing device.

[0089] In this embodiment, the change amount / change rate of the water quality parameter can reflect the dissolution change situation of the stains in the soaking water.

[0090] S11. If so, control the clamping device to perform a release action to loosen the clamped clothes. When the current change amount / change rate of the water quality parameter is less than the preset increment of the previous change amount / change rate, that is, at this time, the agitation does not cause a large fluctuation in the water quality parameter of the inner cylinder, indicating that the change amount / change rate of the water quality parameter basically remains unchanged, and most of the stains on the clothes have been dissolved in the water. Therefore, the agitation can be stopped. Even if there are local stains on the clothes that have not been dissolved, it does not affect the current soaking effect and will not exceed the washing capacity of the subsequent washing program and rinsing program. At this time, control the clamping device to perform a release action to loosen the clothes, terminate the state of clamping the clothes, and do not affect the subsequent laundry process.

[0091] S12. Otherwise, continue to agitate the clothes. When the current change amount / change rate of the water quality parameter is not less than the preset increment of the previous change amount / change rate, it indicates that the change amount / change rate of the water quality parameter is still in a rapid growth state, and most of the stains on the clothes have not been dissolved in the water. It is necessary to continue to agitate the clothes to further dissolve the stains on the clothes in the water. Then, by comparing the water quality parameter with the preset value, the soaking effect of the washing device can be accurately obtained. After the water quality of the soaking water after the clothes are agitated reaches the corresponding set working condition, then control the clamping device to perform a release action to loosen the clothes, terminate the state of clamping the clothes, and do not affect the subsequent laundry process, making the pre-soaking process control of the washing device precise and intelligent.

[0092] In some embodiments, after controlling the water inlet valve to open to fill water into the inner cylinder, the following steps are included:

[0093] During the water inlet process or after the water inlet ends, control the inner cylinder to rotate.

[0094] Such asFigure 4 As shown, during the water inlet process or after the water inlet ends, controlling the rotation of the inner cylinder includes the following steps:

[0095] S41. Obtain the water level information of the inner cylinder; it can be configured to obtain the real-time water level information of the inner cylinder during the water inlet process, or it can be configured to obtain the pre-soaking water level information in the inner cylinder after the water inlet ends.

[0096] S42. Control the rotation amplitude of the inner cylinder according to the water level information of the inner cylinder so that the clothes do not exceed the current water surface. It can be configured to control the rotation amplitude of the inner cylinder according to the real-time water level information during the water inlet process so that the clothes do not exceed the current water surface; or it can be configured to control the rotation amplitude of the inner cylinder according to the pre-soaking water level information after the water inlet ends so that the clothes do not exceed the pre-soaking water surface.

[0097] As Figure 5 shown, controlling the rotation amplitude of the inner cylinder according to the water level information of the inner cylinder so that the clothes do not exceed the current water surface includes the following steps:

[0098] S421. Obtain the position of the clamping device clamping the clothes; in this embodiment, the detection method of the position of the lifting rib can be detected by detection devices such as position sensors, and the position sensor can continuously and real-time collect the current position information of the lifting rib.

[0099] The corresponding clamping action execution positions of the clamping devices on both sides of the lifting rib are different. In this embodiment, the corresponding clamping action execution positions of the clamping devices on both sides of the lifting rib are preset in the washing device, which can be obtained through experimental empirical values, or can be obtained through simulation modeling analysis of the washing device, etc.

[0100] S422. Judge whether the clothes are about to exceed the water surface by comparing the position of the clamping device with the current water level information of the inner cylinder; in this embodiment, the water level information in the inner cylinder can be collected by a water level sensor arranged on the cylinder body.

[0101] In some embodiments, a water level sensor can also be arranged on the lifting rib. When the water level sensor on the lifting rib is out of the water surface of the inner cylinder, the water level information cannot be collected; when the water level sensor on the lifting rib is not out of the water surface of the inner cylinder, the water level information can be collected, indicating that the lifting rib is still in the water of the inner cylinder.

[0102] S423. When the clothes are about to exceed the water surface, control the inner cylinder to rotate in the reverse direction.

[0103] In this embodiment, as Figure 6 shown in (a) below, after controlling the clamping device 3 on the lifting rib 2 in the inner cylinder 1 of the washing device to perform a clamping action before the water inlet, the water inlet valve starts to let water in. When the water level passes over the lifting rib 2, control the rotation of the inner cylinder until it rotates to as Figure 6At the position shown in (b) of the figure, the position of the clamping device 3 clamping the clothes is about to exceed the water level in the inner tub. At this time, the inner tub is controlled to rotate in the reverse direction so that the clothes will not separate from the water body, preventing the clamped clothes from being overly pulled and damaged due to excessive water content and weight after exceeding the water level.

[0104] In this embodiment, after the cylinder rotates in the reverse direction, from Figure 6 the position shown in (b) of the figure and rotates to Figure 6 the position shown in (a) of the figure. At this time, the clothes clamped by the clamping device 3 are about to exceed the water surface in the inner tub, and the clamping device 3 is about to reach the water surface in the inner tub. To prevent damage to the clothes, the inner tub can be controlled to rotate in the reverse direction again. Since Figure 6 the rotation direction of the inner tub shown in (a) of the figure is different from the direction in which the clamping device 3 extends from one side of the lifting rib 2. During the clockwise rotation, the clothes clamped by the clamping device 3 extending from the right side of the lifting rib 2 are in a state of being pulled. The clothes can be pulled out of the water body only after the clamping device 3 clamping the clothes emerges from the water surface first. Therefore, at this time, a reverse rotation signal is formed by judging whether the clamping device 3 clamping the clothes exceeds the current water level information of the inner tub; since Figure 6 the rotation direction of the inner tub shown in (b) of the figure is the same as the direction in which the clamping device 3 extends from one side of the lifting rib 2. During the counterclockwise rotation, the clothes clamped by the clamping device 3 extending from the right side of the lifting rib 3 are in a state of being pushed. The clothes emerge from the water surface first and then the clamping device 3 can separate from the water surface. Therefore, at this time, a reverse rotation signal is formed by judging whether the clamping device 3 reaches the water level of the inner tub. It should be understood that the same applies to the clamping device 3 extending from the left side of the lifting rib 2 and will not be elaborated here.

[0105] When the clothes do not exceed the water surface, the inner tub is controlled to continue rotating.

[0106] When the clothes move in the water environment of the inner tub under the traction of the clamping device and the stains on the clothes are fully and evenly dissolved in the water, the clamping device can be appropriately controlled to perform a release action to loosen the clamped clothes, avoiding excessive pulling of the clothes and damaging the clothes. As Figure 7 shown, the following steps are further included:

[0107] S13. Obtain the soaking duration or the preset release time; wherein, the soaking duration or the preset release time is determined based on the material information and / or weight information of the clothing. For example, the soaking duration of cotton clothing is several minutes, the soaking duration of silk fabric is about 10 minutes, and the soaking duration of polyester fabric / acrylic fabric / nylon fabric is 15 minutes. Usually, there is a corresponding relationship between the clothing weight and the water intake preset in the washing device. On the premise that the water intake is known, it can be experimentally determined in advance the time when stains on clothes are fully and evenly dissolved in the water when clothes of different weights move in the water environment of the inner cylinder under the traction of the clamping device. This time is taken as the soaking duration. It can also be experimentally determined in advance how many times clothes of different materials and weights need to move back and forth in the water environment of the inner cylinder under the traction of the clamping device to make the stains on the clothes fully and evenly dissolve in the water. The time for the clamping device to traction the clothes to move back and forth in the water environment of the inner cylinder is preset in the washing device as the release time. For example, the pre-soaking time of a 200g cotton T-shirt is T1 min, and the preset release time of a 200g cotton T-shirt is T2 min, where T2 < T1.

[0108] The above-mentioned material information and weight information of the clothing can be detected by sensors built in the washing device, or can be fed back to the washing device through the function interface on the washing device, an external terminal communicating with the washing device, etc.

[0109] S14. If the current soaking time reaches the soaking duration or the preset release time, control the clamping device to perform a release action to release the clamped clothing. That is, the clamping device can release the clothing after soaking or during soaking, and make adaptive adjustments according to the different clothes washed by the washing device.

[0110] In this embodiment, after the clothing is agitated by the clamping device, the clothing can be released during the subsequent laundry process without always clamping the clothing. After release, the clamping device can be retracted into the lifting rib without affecting the subsequent laundry process.

[0111] This embodiment can automatically determine the soaking duration or the preset release time corresponding to the material information and / or weight information of the clothing based on the material information and / or weight information of the clothing, so that while the stains on the clothing are fully and evenly dissolved in the water, the pulling damage to the clothing is minimized, and the washing degree of the clothing is improved.

[0112] This embodiment provides a pre-soaking control method for a washing device. By controlling the clamping device on the lifting rib to perform a clamping action, the clothes move in the water environment of the inner cylinder under the traction of the clamping device, which can stir the clothes during the pre-soaking process. The effect of stirring the clothes is good, which can accelerate the softening of the stains on the clothes, the stains dissolved in the water are uniform, achieving a good soaking effect, and can maximize the role of the soaking process. Since the clothes are stirred during the low-speed rotation of the inner cylinder, the wear on the clothes can be reduced. By adjusting the washing parameters of the subsequent washing program according to the water quality parameters after stirring the clothes, the washing process of the washing device becomes more intelligent.

[0113] Embodiment 2

[0114] A washing device applies the pre-soaking control method for the washing device provided in Embodiment 1. For the detailed description of the method, reference can be made to the corresponding description in the above method embodiment, which will not be elaborated here.

[0115] The washing device provided in this embodiment is designed with a pre-soaking program. The washing device can separately set pre-soaking related options on the function interface. In order to save the user's operation time and make more efficient use of the function interface, the pre-soaking function can also be nested in other washing processes. For example, the pre-soaking function can be nested in the intensive washing process.

[0116] In some embodiments, the washing device can be a mini washing device for washing intimate clothes, a wall-mounted washing device for washing a small amount of children's clothes, or a medium and large-sized washing device for washing a small amount of precious fabric clothes.

[0117] In this embodiment, a lifting rib is installed on the inner cylinder of the washing device, and a clamping device capable of clamping clothes is loaded on the lifting rib. In some embodiments, the clamping device can also be expressed as a picking device or a grasping device or a clamping device, etc. In this embodiment, it can be configured that the clamping device is driven by a power mechanism to move, so as to perform a clamping action. When controlling the clamping device to perform a clamping action, the power mechanism drives the corresponding clamping device to extend from the installation opening formed on the surface of the lifting rib until it is clamped, so as to clamp the clothes near the lifting rib, and further provide pulling, stirring, shaking, etc. of the clothes during the pre-soaking process.

[0118] In this embodiment, the user places the clothes in the inner cylinder of the washing device. Due to the action of gravity, the clothes are usually in the bottom area of the inner cylinder. In order to ensure the clamping accuracy of the clamping device, the inner cylinder can also be controlled to rotate several circles first, and the clothes roll at the bottom of the cylinder body as the cylinder body rotates. When the lifting rib loaded with the clamping device drives the clothes to rotate to the bottom area of the cylinder body together, the clamping device is controlled to perform a clamping action. It should be noted that the bottom area of the inner cylinder does not only refer to the physically lowest point of the inner cylinder, but refers to the position where the lifting rib rotates to the bottom of the inner cylinder and can clamp the clothes located at the bottom of the cylinder body. As Figure 6As shown, the clamping device 3 on the lifting rib 2 in the inner drum 1 of the washing device performs a clamping action at the illustrated position to achieve clothing clamping.

[0119] Inside the inner drum, the lifting rib divides the inner drum space near it into two parts according to its position in the drum, forming spaces on both sides of the lifting rib. Clamping devices can be arranged on both sides of the lifting rib. In this embodiment, the specific position of the clamping device arranged on the lifting rib is not limited. When the actual operating conditions of the washing device are different, the clothing can be located on either side of the lifting rib. Correspondingly, in terms of spatial distribution, the direction in which the clamping device extends out of the open end from the lifting rib generally corresponds to the spaces on both sides of the lifting rib, and the clamping of clothing on both sides of the lifting rib can be achieved.

[0120] It should be noted that Figure 6 the clamping device 3 schematically shown on each lifting rib is only used to indicate that there is a clamping device on the lifting rib. During actual use, when the clamping device 3 is not clamping clothing, it can be retracted into the lifting rib 2. And it is not limited to having clamping devices on both sides of the lifting rib. As shown in Figure 6 there can be a clamping device on one side of the lifting rib, or there can be clamping devices on both sides of the lifting rib.

[0121] In this embodiment, the inner drum can be configured to be driven by an inner drum driving device to rotate. Among them, the inner drum driving device includes but is not limited to a pulley driven by a motor or a direct drive motor, etc. It should be noted that in order to ensure the clamping effect, protect the internal power supply device of the drum that supplies power to the clamping components in the drum, and minimize the wear on the clothing, the washing device controls the inner drum driving device to drive the inner drum to rotate at a low speed here, that is, the rotation speed at this time is lower than the rotation speed of the inner drum during washing, dehydration and other processes.

[0122] After pre-soaking, the clothing is fully soaked by the water in the inner drum and moves in the water environment of the inner drum under the traction of the clamping device, realizing the agitation of the clothing during the pre-soaking process, accelerating the dissolution of local dirt, and the stains on the clothing are evenly dissolved in the water. For a washing device with a water quality detection function, in cooperation with water quality detection, the water quality situation can be judged, including stain types, dirt levels, etc.

[0123] The washing device is used to implement the pre-soaking control method of the washing device provided in Embodiment 1, judge whether the currently executed program is a pre-soaking program; if it is a pre-soaking program, control the clamping device on the lifting rib in the inner drum of the washing device to perform a clamping action before water inlet; control the water inlet valve to open to fill water into the inner drum; control the inner drum to rotate, and the clothing moves in the water environment of the inner drum under the traction of the clamping device to realize the agitation of the clothing during the pre-soaking process.

[0124] This embodiment provides a washing device. By controlling the clamping device on the lifting rib to perform a clamping action, the clothes move in the water environment of the inner cylinder under the traction of the clamping device, which can stir the clothes during the pre-soaking process, with a good effect of stirring the clothes, accelerating the softening of the stains on the clothes, making the stains dissolved in the water uniform, achieving a good soaking effect, and maximizing the role of the soaking process. Since the clothes are stirred during the low-speed rotation of the inner cylinder, the wear on the clothes can be reduced. By adjusting the washing parameters of the subsequent washing program according to the water quality parameters after stirring the clothes, the washing process of the washing device becomes more intelligent.
