[0001] The present application relates to the technical field of laundry dewatering, in particular to a dewatering processing method and system of a smart washing machine and the smart washing machine. BACKGROUND

[0002] As a traditional household cleaning appliance, the core function of a washing machine is to realize laundry washing. However, people's requirements for the daily use of washing machines are also constantly improving. The rapid development of Internet of Things technology has led to the birth of the concept of smart washing machines. In addition to realizing the multi-functional expansion of washing machines, smart washing machine technology also optimizes traditional laundry washing programs based on different function sensors and corresponding algorithms, thereby realizing intelligent washing and protection of laundry.

[0003] However, current washing machines tend to be compatible with large load laundry dewatering situations, while ignoring small load laundry dewatering situations. When small load laundry, especially single small load laundry, is dewatered, its area is much smaller than that of large load laundry dewatering, and unevenly distributed laundry is prone to clumping and forming a large eccentricity, thereby causing no dewatering alarm or dewatering difficulty.

[0004] The prior art also has the problem of no dewatering alarm or difficulty in dewatering when processing single small load laundry, and therefore the prior art remains to be improved. SUMMARY

[0005] The technical problem to be solved by the present application is that, in view of the defects of the prior art, the present application provides a dewatering processing method and system of a smart washing machine and the smart washing machine, to solve the problem of no dewatering alarm or difficulty in dewatering when processing single small load laundry existing in the prior art dewatering processing method.

[0006] The technical solution adopted by the present application to solve the technical problem is as follows: In a first aspect, the present application provides a dewatering processing method of a smart washing machine, comprising: performing first eccentricity detection on the laundry to be dewatered to obtain a first eccentricity value; when the first eccentricity value meets a preset eccentricity value threshold, performing forward weighing and second eccentricity detection on the laundry to be dewatered to obtain a first weight value and a second eccentricity value of the laundry to be dewatered; when the second eccentricity value meets the preset eccentricity value threshold, dewatering the laundry to be dewatered based on the first weight value and a preset first dewatering strategy; when any one of the first eccentricity value and the second eccentricity value does not meet the preset eccentricity value threshold, dewatering the laundry to be dewatered using a preset second dewatering strategy.

[0008] In an implementation manner, when the first eccentricity value meets a preset eccentricity value threshold, the forward weighing and second eccentricity detection are performed on the clothes to be dehydrated to obtain a first weight value and a second eccentricity value of the clothes to be dehydrated, and the first eccentricity value meeting the preset eccentricity value threshold comprises: determining whether the first eccentricity value meets the preset eccentricity value threshold; When the first eccentricity value meets the preset eccentricity value threshold, the rotation speed of the intelligent washing machine is controlled to reach a second rotation speed, and the forward weighing is performed on the clothes to be dehydrated at the second rotation speed to obtain the first weight value of the clothes to be dehydrated. The rotation speed of the intelligent washing machine is controlled to reach a first rotation speed, and the second eccentricity detection is performed on the clothes to be dehydrated after the forward weighing at the first rotation speed to obtain a second eccentricity value. The numerical value of the second rotation speed is greater than the numerical value of the first rotation speed, and the rotation direction of the intelligent washing machine corresponding to the second rotation speed is the same as the rotation direction of the intelligent washing machine corresponding to the first rotation speed.

[0009] In an implementation manner, when the second eccentricity value meets a preset eccentricity value threshold, a preset first dehydration strategy is used to perform dehydration on the clothes to be dehydrated, and the second eccentricity value meeting the preset eccentricity value threshold comprises: determining whether the second eccentricity value meets the preset eccentricity value threshold; When the second eccentricity value meets the preset eccentricity value threshold, the rotation speed of the intelligent washing machine is controlled to reach a third rotation speed, and the reverse shaking is performed on the clothes to be dehydrated at the third rotation speed. The rotation speed of the intelligent washing machine is controlled to reach a fourth rotation speed based on the first weight value, and the dehydration is performed on the clothes to be dehydrated after the reverse shaking at the fourth rotation speed. The numerical value of the fourth rotation speed is greater than the numerical value of the third rotation speed, and the rotation direction of the intelligent washing machine corresponding to the fourth rotation speed is opposite to the rotation direction of the intelligent washing machine corresponding to the third rotation speed.

[0010] In an implementation manner, when any one of the first eccentricity value and the second eccentricity value does not meet the preset eccentricity value threshold, a preset second dehydration strategy is used to perform dehydration on the clothes to be dehydrated, and the any one of the first eccentricity value and the second eccentricity value not meeting the preset eccentricity value threshold comprises: When the first eccentricity value does not meet the preset eccentricity value threshold, it is determined that the forward weighing of the clothes to be dehydrated fails, and the preset second dehydration strategy is used to perform dehydration on the clothes to be dehydrated. When the second eccentricity value does not satisfy the preset eccentricity value threshold, it is determined that the clothes to be dewatered do not satisfy the first dewatering strategy, and the clothes to be dewatered are dewatered using the preset second dewatering strategy.

[0011] In an implementation manner, the dewatering of the clothes to be dewatered using the preset second dewatering strategy comprises: controlling the rotation speed of the intelligent washing machine to reach a fifth rotation speed, and performing reverse weighing on the clothes to be dewatered at the fifth rotation speed to obtain a third eccentricity value and a second weight value; controlling the rotation speed of the intelligent washing machine to reach a sixth rotation speed based on the third eccentricity value and the second weight value, and dewatering the clothes to be dewatered after the reverse shaking and scattering at the sixth rotation speed; The numerical value of the sixth rotation speed is greater than that of the fifth rotation speed, and the rotation direction of the intelligent washing machine corresponding to the sixth rotation speed is the same as that of the intelligent washing machine corresponding to the fifth rotation speed.

[0012] In an implementation manner, the controlling the rotation speed of the intelligent washing machine to reach a sixth rotation speed based on the third eccentricity value and the second weight value comprises: determining whether the second weight value satisfies a weight threshold of the second dewatering strategy; If the second weight value satisfies the weight threshold of the second dewatering strategy, the maximum rotation speed in a preset dewatering assignment table corresponding to the third eccentricity value is taken as the sixth rotation speed.

The first dehydration strategy is used to dehydrate the clothes to be dehydrated when the clothes to be dehydrated meet the forward dehydration condition, and the second dehydration strategy is used to dehydrate the clothes to be dehydrated when the clothes to be dehydrated meet the reverse dehydration condition. By using multiple dehydration strategies to replace the single dehydration strategy in the prior art, the second dehydration strategy is used for the clothes of the "single small load" type whose eccentricity value does not meet the preset eccentricity value threshold, thereby avoiding the problems of repeated shaking, water replenishment, and even dehydration failure and shutdown of the clothes during dehydration, improving the success rate of one-time dehydration, saving the time and energy consumption of the smart washing machine, and improving the working efficiency of the smart washing machine.

[0021] In order to make the objects, technical solutions and advantages of the present application clearer and more apparent, the present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and not to limit the present application.

[0022] Exemplary method The existing washing machine tends to be compatible with the dehydration of large load clothes, ignoring the dehydration of single and small load clothes. The traditional dehydration method is to weigh and shake the clothes to be dehydrated in one direction after draining. However, the area of single and small load clothes is much smaller than that of large load clothes during dehydration, so it cannot be evenly distributed in the washing machine, and it is easy to clump and form a large eccentricity, thereby causing the dehydration alarm or dehydration difficulty, such as repeated shaking, water replenishment, and even dehydration failure and shutdown. These phenomena cause the success rate of one-time dehydration of the washing machine to be too low when dehydrating single and small load clothes.

[0023] In view of the above technical problems, the dehydration processing method of the intelligent washing machine provided in the embodiments of the present application comprises the following steps:

[0024] As shown in Figure 1 The dehydration processing method of the intelligent washing machine provided in the embodiments of the present application comprises the following steps: It should be noted that the dehydration processing method of the intelligent washing machine is applied to the intelligent washing machine. The intelligent washing machine of the present application is a washing machine integrating Internet of Things, sensors, algorithms and other technologies. The core is to improve the intelligence of the washing machine and reduce manual operation to improve washing efficiency and experience. The intelligent washing machine refers to a washing machine that is not limited to a single structure type. For example, the intelligent washing machine can be a drum washing machine, a pulsator washing machine or a washing-drying integrated machine, etc.

[0025] In the embodiment, the intelligent washing machine is a drum washing machine, which is provided with a corresponding water inlet valve, a gravity sensor, an acceleration sensor, a drainage pump, a drum motor and the like. When the intelligent washing machine starts the above components, corresponding program instructions and the like are executed, for example, water inlet instructions, cleaning instructions, drainage instructions, weighing instructions and dehydration instructions and the like.

[0026] In an implementation manner of the embodiment, before step S100, the following steps are further included: Step S001, obtaining the clothes to be cleaned, and processing the clothes to be cleaned to obtain the clothes to be dehydrated.

[0027] In the embodiment, the clothes to be cleaned are obtained, and the clothes to be cleaned are put into the intelligent washing machine. After the intelligent washing machine is started, the dry cloth weight information is obtained by dry cloth weighing of the clothes to be cleaned, and the dry cloth weight information is subjected to eccentricity detection to obtain the dry cloth weight gear information. After a corresponding cleaning gear is selected according to the dry cloth weight gear information, a corresponding water level frequency and a detergent dosage are obtained, for example, 1 kg of dry cloth corresponds to a first water level frequency, 2 kg of dry cloth corresponds to a second water level frequency, and so on, and a corresponding detergent dosage is set. Then, the intelligent washing machine water inlet valve is watered to reach the target water level corresponding to the dry cloth weight, and the corresponding detergent is put in, and the cleaning work of the clothes to be cleaned is started. After the cleaning work is completed, drainage processing is performed to obtain the clothes to be cleaned.

[0028] In the embodiment, the dirtiness of the clothes can also be detected by the dirtiness sensor, and the detergent dosage is adjusted based on the dirtiness detection result.

[0029] Step S100, first eccentricity detection is performed on the clothes to be dehydrated to obtain a first eccentricity value.

[0030] In the embodiment, the clothes to be dehydrated refer to the clothes obtained after the clothes to be cleaned are put into the washing machine and the water inlet, washing and drainage steps are performed. The clothes to be dehydrated absorb a large amount of water and have a high water content, and need to be subjected to a dehydration step.

[0031] Specifically, in an implementation manner of the embodiment, step S100 includes the following steps: Step S101, controlling the rotation speed of the intelligent washing machine to reach a first rotation speed.

[0032] In the embodiment, the first rotation speed refers to the rotation speed for first eccentricity detection of the clothes to be dehydrated, which is generally set to 90 rpm.

[0033] It should be noted that the rotation speed of the intelligent washing machine refers to the rotation speed of the barrel in which the clothes to be cleaned are placed in the intelligent washing machine. In the present application, the intelligent washing machine is a drum washing machine, so the rotation speed of the intelligent washing machine in the present application is the rotation speed of the drum in the intelligent washing machine.

[0034] Step S102, first eccentricity detection is performed on the laundry to be dewatered at the first rotating speed to obtain the first eccentricity value.

[0035] In this embodiment, first eccentricity detection is performed on the laundry to be dewatered at the first rotating speed to obtain the first eccentricity value, which is used to determine whether the laundry to be dewatered can be successfully weighed in the forward direction.

[0036] As shown in Figure 1 The present application provides a dewatering method for a smart washing machine, which comprises the following steps: Step S200, when the first eccentricity value meets a preset eccentricity value threshold, forward weighing and second eccentricity detection are performed on the laundry to be dewatered to obtain a first weight value of the laundry to be dewatered and a second eccentricity value.

[0037] In this embodiment, the preset eccentricity value threshold is 120.

[0038] Specifically, in one implementation manner of this embodiment, step S200 comprises the following steps: Step S201, it is determined whether the first eccentricity value meets the preset eccentricity value threshold.

[0039] In this embodiment, the preset eccentricity value threshold is used to determine whether the laundry to be dewatered can be successfully weighed in the forward direction. When the first eccentricity value is less than the eccentricity value threshold, it is determined that the laundry to be dewatered cannot be successfully weighed in the forward direction and is not suitable for using the forward dewatering strategy; when the first eccentricity value is not less than the eccentricity value threshold, it is determined that the laundry to be dewatered can be successfully weighed in the forward direction, so the laundry to be dewatered can be weighed in the forward direction and the forward dewatering strategy can be used for dewatering.

[0040] In this embodiment, the rotating speed of the first eccentricity detection is set to 90 rpm, which is also used to prevent the washing machine from colliding with the barrel when being weighed in the forward direction, i.e., the laundry to be dewatered whose first eccentricity value cannot reach the preset eccentricity value threshold may collide with the barrel when being weighed in the forward direction at a higher rotating speed. To avoid this phenomenon, the case where the first eccentricity value is less than the eccentricity value threshold is determined as the laundry to be dewatered being unable to be successfully weighed in the forward direction. At this time, the actual forward weighing step has not been performed, so the first weight value of the laundry to be dewatered at this time cannot be obtained.

[0041] It should be noted that the forward dewatering strategy is a normal dewatering strategy, which corresponds to the first dewatering strategy in the present application and comprises four steps of forward weighing, eccentricity detection, reverse scattering and forward high-speed dewatering.

[0042] Step S202, when the first eccentricity value meets the preset eccentricity value threshold, the speed of the intelligent washing machine is controlled to reach a second speed, and the to-be-dewatered clothes are positively weighed at the second speed to obtain a first weight value of the to-be-dewatered clothes.

[0043] In the embodiment, the second speed refers to a speed for positively weighing the to-be-dewatered clothes, and is generally set to 150 rpm.

[0044] In the embodiment, the first weight value refers to a weight value obtained by positively weighing the to-be-dewatered clothes, which is generally greater than 3 kg. Therefore, the eccentricity value threshold needs to be reasonably set, so that when the actual weight value of the to-be-dewatered clothes is less than 3 kg, the first eccentricity value corresponding to the first eccentricity detection cannot reach the eccentricity value threshold.

[0045] Step S203, the speed of the intelligent washing machine is controlled to reach a first speed, and the to-be-dewatered clothes after positively weighing are subjected to second eccentricity detection at the first speed to obtain a second eccentricity value.

[0046] In the embodiment, the second eccentricity detection refers to eccentricity detection after positively weighing in the positive dewatering strategy, which is used to further judge whether the to-be-dewatered clothes meet the condition of positively weighing. The speed of the second eccentricity detection is set to the same first speed as the first eccentricity detection. The first eccentricity detection can be regarded as a preliminary eccentricity judgment of the to-be-dewatered clothes to avoid hitting the barrel, and the second eccentricity detection is an actual eccentricity judgment of the to-be-dewatered clothes, which is used to obtain the second eccentricity value.

[0047] It should be noted that the numerical value of the second speed is greater than the numerical value of the first speed, and the rotation direction of the intelligent washing machine corresponding to the second speed is the same as the rotation direction of the intelligent washing machine corresponding to the first speed. In the embodiment, the first speed and the second speed are both positive, wherein the first speed is used for eccentricity detection, and the second speed is used for positively weighing.

[0048] In the embodiment, by setting the eccentricity value threshold, it can be judged whether the to-be-washed clothes will hit the barrel during positively weighing according to the first eccentricity value threshold, and it can be judged whether the to-be-washed clothes can use the first dewatering strategy for positive dewatering according to the second eccentricity value threshold. The first weight value obtained by positively weighing facilitates the intelligent washing machine to select the positive dewatering gear according to the first weight value, and improves the success rate of dewatering the to-be-dewatered clothes.

[0049] As shown in FIG. Figure 1 The embodiment of the present application provides a dewatering processing method of an intelligent washing machine, which comprises the following steps: Step S300, when the second eccentricity value meets the preset eccentricity value threshold, the to-be-dewatered clothes are dewatered based on the first weight value and a preset first dewatering strategy.

[0050] Specifically, in an implementation form of the embodiment, step S300 comprises the following steps: Step S301, determining whether the second eccentricity value meets the preset eccentricity value threshold.

[0051] In the embodiment, when the second eccentricity value is less than the eccentricity value threshold, it is determined that the clothes to be dewatered do not meet the first dewatering strategy, i.e., the clothes to be dewatered are not suitable for using the positive dewatering strategy; when the second eccentricity value is not less than the eccentricity value threshold, it is determined that the clothes to be dewatered meet the first dewatering strategy and can use the positive dewatering strategy for dewatering.

[0052] Step S302, when the second eccentricity value meets the preset eccentricity value threshold, controlling the rotation speed of the intelligent washing machine to reach a third rotation speed, and performing reverse shaking of the clothes to be dewatered at the third rotation speed.

[0053] It should be noted that the third rotation speed refers to the rotation speed for performing reverse shaking of the clothes to be dewatered, which is generally set to -45 rpm, wherein the negative sign represents the opposite direction of the positive direction, i.e., the reverse direction. During the reverse shaking process, the rotation speed of the intelligent washing machine slowly increases from 0 rpm to -45 rpm.

[0054] In the implementation example, the reverse shaking is a step subsequent to the eccentricity detection step in the first dewatering strategy. In this step, the intelligent washing machine shakes the large clothes in the reverse direction to adjust the state of the clothes, so as to ensure the dewatering efficiency and safety of the dewatering link and avoid the phenomenon of violent vibration.

[0055] Step S303, controlling the rotation speed of the intelligent washing machine to reach a fourth rotation speed based on the first weight value, and performing dewatering of the clothes to be dewatered after the reverse shaking at the fourth rotation speed.

[0056] In the embodiment, the fourth rotation speed refers to the rotation speed for performing positive high-speed dewatering of the clothes to be dewatered, which generally needs to be set according to the first weight value obtained by positive weighing of the clothes to be dewatered. For example, the clothes to be dewatered within kg can be set to 800 rpm. When the rotation speed of the intelligent washing machine is greater than the fourth rotation speed in value, it is determined that the dewatering is completed.

[0057] In the embodiment, the dewatering of the clothes to be dewatered after the reverse shaking at the fourth rotation speed is the last step in the first dewatering strategy. This step dries the water in the clothes to be dewatered through positive high-speed dewatering, and completes the positive dewatering of the clothes to be dewatered.

[0058] It should be noted that the value of the fourth rotation speed is greater than the value of the third rotation speed, and the rotation direction of the smart washing machine corresponding to the fourth rotation speed is opposite to the rotation direction of the smart washing machine corresponding to the third rotation speed. In the embodiment, the fourth rotation speed is forward, which is used for forward high-speed dewatering, and the third rotation speed is reverse, which is used for reverse shaking.

[0059] As shown in Figure 1 The embodiment of the present application provides a dewatering processing method of a smart washing machine, which comprises the following steps: Step S400, when any one of the first eccentricity value and the second eccentricity value does not satisfy the preset eccentricity value threshold, using a preset second dewatering strategy to dewater the clothes to be dewatered.

[0060] It should be noted that although the final result of the first eccentricity value and the second eccentricity value not satisfying the preset eccentricity value threshold is to use the preset second dewatering strategy to dewater the clothes to be dewatered, the reasons are different. When the first eccentricity value does not satisfy the preset eccentricity value threshold, the clothes to be dewatered may collide with the barrel when being forward weighed, so it is determined that the forward weighing of the clothes to be dewatered fails, and the preset second dewatering strategy is used to dewater the clothes to be dewatered. When the second eccentricity value does not satisfy the preset eccentricity value threshold, it means that the forward weighing has been completed, but the result of the forward weighing may be close to or equal to the set 3kg, so the second eccentricity detection is needed after weighing to determine whether the clothes to be dewatered satisfy the first dewatering strategy. If not, the second dewatering strategy is still needed to dewater the clothes to be dewatered.

[0061] In the embodiment, the second dewatering strategy refers to a reverse dewatering strategy, which includes two steps of reverse weighing and reverse dewatering, and is different from the first dewatering strategy. The second dewatering strategy cancels the reverse shaking step in the first dewatering strategy, combines the forward weighing and the eccentricity detection into a reverse weighing step, and obtains the third eccentricity value and the second weight value of the clothes to be dewatered through the reverse weighing.

[0062] Specifically, in an implementation manner of the embodiment, step S400 comprises the following steps: Step S401, controlling the rotation speed of the smart washing machine to reach a fifth rotation speed, and using the fifth rotation speed to reverse weigh the clothes to be dewatered to obtain a third eccentricity value and a second weight value.

[0063] In the embodiment, the fifth rotating speed refers to a rotating speed for reverse weighing of the laundry to be dewatered, and is generally set as -150 rpm, wherein the negative sign represents a direction opposite to the forward direction, i.e., a reverse direction. During the reverse weighing, the rotating speed of the intelligent washing machine is first slowly increased from 0 rpm to -90 rpm, during which the single small load of the laundry to be dewatered is shaken and scattered, and a third eccentricity value of the laundry to be dewatered in the reverse direction is obtained. Then, the rotating speed of the intelligent washing machine is increased from -90 rpm to -150 rpm, so as to complete the reverse weighing of the laundry to be dewatered and obtain a second weight value.

[0064] It should be noted that, during the reverse shaking and scattering, the laundry is distributed in a small eccentricity, i.e., the third eccentricity value is too small. At this time, the reverse weighing of the laundry to be dewatered can be realized by increasing the rotating speed again. The fifth rotating speed for the reverse weighing is the same as the second rotating speed for the forward weighing in value, and the difference lies in the directions of the two rotating speeds.

[0065] The sixth rotating speed is greater than the fifth rotating speed in value, and the rotating direction of the intelligent washing machine corresponding to the sixth rotating speed is the same as the rotating direction of the intelligent washing machine corresponding to the fifth rotating speed. In the embodiment, the sixth rotating speed and the fifth rotating speed are both reverse directions. The sixth rotating speed is used for reverse high-speed dewatering, and the fifth rotating speed is used for reverse weighing.

[0066] It should be noted that the laundry to be dewatered using the second dewatering strategy is single small load of laundry to be dewatered, which can be understood as a pair of jeans, a bath towel or a down jacket. The weight of the single small load of laundry to be dewatered is generally within 3 kg after drainage. Therefore, the second weight value is also within 3 kg. The single small load of laundry to be dewatered is difficult to be evenly distributed during dewatering due to small area, and is easy to be aggregated to form a large eccentricity. The reverse weighing can avoid reducing the eccentricity of the single small load of laundry to be dewatered, so as to enable dewatering.

[0067] In step S402, the rotating speed of the intelligent washing machine is controlled to reach a sixth rotating speed based on the third eccentricity value and the second weight value, and the single small load of laundry to be dewatered after the reverse shaking and scattering is dewatered at the sixth rotating speed.

[0068] Specifically, in an implementation manner of the embodiment, step S402 includes the following steps. In step S4021, it is judged whether the second weight value meets a weight threshold of the second dewatering strategy.

[0069] It should be noted that the weight threshold of the second dewatering strategy is generally set as 3 kg, i.e., a threshold of single small load of laundry to be dewatered. When the second weight value is less than the weight threshold, it is determined that the laundry to be dewatered is single small load.

[0070] In step S4022, if the second weight value meets the weight threshold of the second dewatering strategy, the maximum rotating speed in the preset dewatering assignment table corresponding to the third eccentricity value is taken as a sixth rotating speed.

[0071] In this embodiment, the sixth rotating speed refers to the rotating speed for reverse high-speed dewatering of the laundry to be dewatered. Generally, the maximum rotating speed corresponding to the third eccentricity value obtained by reverse weighing of the laundry to be dewatered is searched in the dewatering assignment table, and the maximum rotating speed is taken as the rotating speed for reverse high-speed dewatering. For example, if the weight value of the laundry to be dewatered within 3 kg meets the weight threshold of the second dewatering strategy, the maximum rotating speed in the preset dewatering assignment table corresponding to the third eccentricity value is searched, and the maximum rotating speed is set. When the rotating speed of the intelligent washing machine is greater than the sixth rotating speed in value, it is determined that the dewatering is completed.

[0072] In this embodiment, the preset dewatering assignment table is shown in Table 1.

[0073] Table 1: Preset dewatering assignment table.

[0074]

[0075] In this embodiment, when the eccentricity value is 80, the maximum rotating speed in the preset dewatering assignment table is 800 rpm, that is, when the rotating speed of the intelligent washing machine is greater than or equal to 800 in value, the dewatering is completed. This embodiment is reverse dewatering, so the sixth rotating speed is -800 rpm.

[0076] In this embodiment, the laundry to be dewatered is divided into normal condition and single small load condition by forward weighing or reverse weighing of the laundry to be dewatered. The first dewatering strategy is used for forward dewatering of the laundry to be dewatered for the normal condition. The second dewatering strategy is used for reverse dewatering of the laundry to be dewatered for the single small load condition. Unlike the traditional washing machine which only has a forward dewatering method, the second dewatering strategy cancels the reverse shaking step. The reverse rotating speed of the intelligent washing machine is gradually increased, so that the reverse weighing step can generate quantifiable weighing values and eccentricity values. Without adding any hardware, the existing sensors of the intelligent washing machine can simultaneously satisfy the reverse shaking, reverse eccentricity detection and reverse weighing. Thus, the single small load laundry can avoid forming a large eccentricity during the reverse weighing process. The single small load laundry with small eccentricity is directly dewatered based on the reverse weighing result and the dewatering assignment table, which avoids the phenomenon of repeated shaking, water supplementing and even dewatering failure of the single small load laundry caused by forward weighing, effectively improves the success rate of one-time dewatering, and avoids the situation of no dewatering alarm or difficult dewatering.

[0077] Exemplary apparatus Based on the above embodiments, the present application also provides a dewatering processing system of an intelligent washing machine, comprising: The eccentricity detection module is configured to perform first eccentricity detection on the clothes to be dehydrated to obtain a first eccentricity value, and perform second eccentricity detection on the clothes to be dehydrated to obtain a second eccentricity value. The eccentricity judgment module is configured to judge whether the first eccentricity value meets a preset eccentricity value threshold, and judge whether the second eccentricity value meets the preset eccentricity value threshold. The forward weighing module is configured to perform forward weighing on the clothes to be dehydrated to obtain a first weight value of the clothes to be dehydrated when the first eccentricity value meets the preset eccentricity value threshold. The forward dehydration module is configured to perform dehydration on the clothes to be dehydrated using a preset first dehydration strategy when the second eccentricity value meets the preset eccentricity value threshold. The reverse dehydration module is configured to perform dehydration on the clothes to be dehydrated using a preset second dehydration strategy when any one of the first eccentricity value and the second eccentricity value does not meet the preset eccentricity value threshold.

[0078] The above technical solution achieves the following technical effects: The forward weighing module and the reverse dehydration module are used to perform forward weighing or reverse weighing on the clothes to be dehydrated, so that the clothes to be dehydrated are divided into normal cases and single-piece small load cases. The first dehydration strategy is used to realize forward dehydration of the clothes to be dehydrated for the normal cases by the forward dehydration module. The second dehydration strategy is used to realize reverse dehydration of the clothes to be dehydrated for the single-piece small load case by the reverse dehydration module. Unlike the traditional washing machine which only has a forward dehydration mode, the reverse dehydration module cancels the reverse shaking step. The reverse speed of the intelligent washing machine is gradually increased, so that the reverse weighing step can generate quantifiable weighing values and eccentricity values. Without adding any hardware, the existing sensors of the intelligent washing machine can meet the requirements of reverse shaking, reverse eccentricity detection and reverse weighing at the same time. Thus, the single-piece small load clothes can avoid forming a large eccentricity during the reverse weighing process. The single-piece small load clothes with small eccentricity are directly dehydrated based on the reverse weighing result and a dehydration assignment table, which avoids the phenomenon that the single-piece small load clothes are repeatedly shaken, watered and even dehydrated to fail to stop during forward weighing by the forward weighing module, effectively improves the success rate of one-time dehydration, and avoids the situation of no dehydration alarm or difficult dehydration.
