[0002] With the continuous upgrading of washing machines such as drum washing machines and the upgrading of user needs, consumers have higher requirements for the cleanliness of clothes. The cleanliness of clothes is not only related to the setting of the washing program of the washing machine and the amount of detergent used, but also to the cleanliness between the inner and outer drums. There is a gap between the inner and outer drums of the washing machine, and the washing water with dirt is easy to adhere to the outer surface of the inner drum and the inner surface of the outer drum. If it is not cleaned in time, it is easy to cause the dirt to be re-contaminated on the clothes, causing secondary pollution.

[0069] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0070] See also Figure 1 , Figure 1 The first flow chart of the control method of the washing machine provided by the embodiment of the present application. The embodiment of the present application provides a control method of a washing machine, wherein the washing machine can be a drum washing machine or a pulsator washing machine. The washing principle of the pulsator washing machine is different from that of the drum washing machine. The drum bottom of the pulsator washing machine is equipped with a disc pulsator with protruding ribs. Driven by the pulsator, the water flow in the drum forms a vortex that sometimes rotates right and sometimes rotates left, driving the fabric to rotate and tumble, so that the dirt on the clothes can be removed. The drum washing machine is designed to imitate the principle of a hammer hitting clothes. When the drum rotates, it generates a huge centrifugal force to perform repeated movements, and the combined action of washing powder and water makes the clothes clean. Of course, the washing machine can also be of other types, and examples are not given here one by one. The embodiment of the present application takes the drum washing machine as an example for explanation, and it should not be understood as a limitation on the type of washing machine. Exemplarily, the washing machine includes an inner drum and an outer drum sleeved outside the inner drum, the inner drum and the outer drum are coaxially arranged, and the inner drum can rotate relative to the outer drum. The inner drum is used to carry clothes, and the outer drum is used to hold washing water. For example, the inner drum can be provided with a water hole, and the water in the outer drum enters the inner drum through the water hole of the inner drum. With the rotation of the inner drum and the cooperation of the laundry liquid, the clothes are washed. The washing machine is not limited to the above-mentioned parts. For example, the washing machine may also include a housing, a display panel, a motor, a rotating shaft and other parts, which are not described here. The control method of the washing machine includes:

[0071] 101. During the rinsing stage or after the rinsing stage is completed, the water level in the outer drum is controlled to reach a cleaning water level.

[0072] Due to the gap between the inner drum and the outer drum, during the process in which the water in the outer drum enters the inner drum through the water holes of the inner drum, and during the process in which the water in the inner drum enters the outer drum through its water holes, or in other words, during the process in which the washing water flows between the inner drum and the outer drum, the dirt dropped from the clothes will be deposited on the outer surface of the inner drum and / or the inner surface of the outer drum. If not cleaned in time, the dirt will be re-stained on the clothes and cause secondary pollution to the clothes.

[0073] In the related art, in order to reduce the tediousness of disassembling the washing machine to clean the inner and outer drums, a separate drum cleaning program is set. After washing is completed, the user takes out the clothes and cleans the drum separately. There are at least two problems with the existing independent drum cleaning program: on the one hand, it is necessary to design a separate drum cleaning program, which complicates the control program of the washing machine; on the other hand, in order to reduce the waste of water resources, the drum cleaning program is usually cleaned within a fixed cycle, such as performing a drum cleaning program after washing five clothes. Since the amount of dirt deposited on the drum is different each time the drum is cleaned, using the same cleaning program will result in insufficient dirt cleanliness, continuous dirt deposition, and poor cleaning effect.

[0074] In order to reduce the occurrence of the above-mentioned problems, the embodiment of the present application rinses the outer surface of the inner drum and the inner surface of the outer drum during each washing to reduce the deposition of dirt and improve the cleaning effect of the drum.

[0075] Exemplarily, the outer surface of the inner drum and the inner surface of the outer drum can be rinsed during the rinsing stage or after the rinsing stage is completed. It should be noted that the washing program may include a main washing stage, a rinsing stage, and a dehydration stage. The main washing stage is a stage for washing out impurities and dirt on the clothes. If the process of rinsing the outer surface of the inner drum and the inner surface of the outer drum is added in this stage, it is easy to cause the problem that the subsequent washing will still have dirt deposition and cannot be cleaned. The dehydration stage is a process in which the clothes have been processed and the clothes can be taken out or dried after the dehydration is completed. This stage is no longer suitable for water intake. Therefore, it is not suitable to put the rinsing of the outer surface of the inner drum and the inner surface of the outer drum into the dehydration stage. In summary, since the clothes are still in a state of high humidity during the rinsing stage or after the rinsing stage is completed, and the dirt on the clothes has been basically washed out, the drum can be cleaned in this process, which does not affect the processing state of the clothes and can clean the dirt washed out during the washing process.

[0076] The process of flushing the outer surface of the inner cylinder and the inner surface of the outer cylinder may be as follows: after the rinsing stage or after the rinsing stage is completed, the water level in the outer cylinder is controlled to reach the clean water level. The clean water level is the appropriate water level height for cleaning the outer cylinder and the inner cylinder. The water level height with the best cleanliness can be obtained through multiple experimental calibrations, or the water level height can be determined based on empirical values. For example, the clean water level can be greater than the water level height in the rinsing stage. At the clean water level, the inner cylinder is cleaned by driving the water flow to perform a cutting motion through the rotation of the inner cylinder.

[0077] 102. The inner cylinder is controlled to rotate to drive the water flow to agitate between the inner cylinder and the outer cylinder to wash the outer surface of the inner cylinder and the inner surface of the outer cylinder.

[0078] Flushing the outer surface of the inner cylinder and the inner surface of the outer cylinder can be achieved by driving the water flow under the rotation of the inner cylinder. It can be understood that the inner cylinder can be controlled to rotate, and the inner cylinder can drive the water flow to agitate between the inner cylinder and the outer cylinder to flush the outer surface of the inner cylinder and the inner surface of the outer cylinder. Under the clean water level, the inner cylinder is driven by the rotation of the inner cylinder to drive the water flow to perform a cutting motion to clean the cylinder.

[0079] The inner drum rotation speed may be a relatively high speed, such as a speed greater than or equal to 80 rpm. At this time, the centrifugal force exerted on the clothes is greater than their gravity, so that the clothes can be attached to the wall of the inner drum to prevent at least part of the water in the outer drum from entering the inner drum, thereby reducing the probability of dirt sticking to the clothes.

[0080] In the control method of the washing machine provided in the embodiment of the present application, by flushing the outer surface of the inner drum and the inner surface of the outer drum during each washing process instead of cleaning in a fixed cycle, the deposition of dirt can be reduced and the cleaning effect can be improved; and there is no need to set up a separate drum cleaning program, which can simplify the program design and reduce the impact on the washed clothes.

[0081] Please combine Figure 1 Also see Figure 2 As shown, Figure 2 This is a second flow chart of the control method of the washing machine provided in the embodiment of the present application. The embodiment of the present application also provides a control method of the washing machine, including:

[0082] 201. Before washing, determine a rinsing time for rinsing the outer surface of the inner drum and the inner surface of the outer drum according to at least one of the weight of the clothes in the inner drum, the material of the clothes, and the washing time of the main washing stage.

[0083] For the flushing time of the drum cleaning, the flushing time for flushing the outer surface of the inner drum and the inner surface of the outer drum can be determined according to at least one of the weight of the clothes in the inner drum, the material of the clothes, and the washing time of the main washing stage. It should be noted that the dirt between the inner drum and the outer drum is mainly formed by the deposition of fibers shed from the clothes, and the amount of fiber shedding corresponding to different weights of clothes is different; different clothing materials correspond to different washing mechanical forces, and the amount of fiber shedding corresponding to different washing mechanical forces is also different, such as the washing mechanical forces of cotton and linen washing and four-piece washing programs are different. When designing the washing program, the washing force is determined according to the material of the clothes; the washing time also determines the amount of fiber shedding. The longer the washing time, the greater the amount of fiber shedding. Therefore, the flushing time of the drum cleaning can be determined according to at least one of the weight of the clothes in the inner drum, the material of the clothes, and the washing time of the main washing stage.

[0084] Among them, the weight of the clothes, the material of the clothes, and the washing time of the main washing stage can all be determined before washing. For example, after putting the clothes into the inner drum, the clothes can be weighed to obtain the weight of the clothes. For another example, when the user selects a washing program such as cotton and linen washing or four-piece washing, or by setting a sensor such as camera shooting, the material of the clothes can be determined, and the washing time of the main washing program can be calculated according to the set program. Therefore, before washing starts, the rinsing time for rinsing the outer surface of the inner drum and the inner surface of the outer drum can be determined.

[0085] There are at least three ways to determine the flushing time for drum cleaning in the embodiment of the present application, which will be described below respectively.

[0086] The first method is to determine the flushing time for drum cleaning based on the weight of the clothes. For example, obtain the weight of the clothes in the inner drum. If the weight of the clothes is within the preset weight range, the first flushing time t1 is calculated based on the clothes weight WF1, the standard weight WF0, the flushing time t0 corresponding to the standard weight, and the first coefficient k1, for example, t1=k1*WF1 / WF0*t0. Among them, the clothes weight WF1 can be obtained by weighing. The standard weight WF0 can be determined based on experiments, such as setting different clothes materials under the same clothes weight, and calibrating the standard weight WF0 for each clothes material. For example, the standard weight WF0 can be set according to the half-load of the cotton material, such as the 10kg model is calibrated according to 5kg. The flushing time t0 is determined according to the standard weight, which can also be called the standard flushing time, which can be obtained based on multiple experiments. The first coefficient k1 is a parameter coefficient for time adjustment according to the material of clothing. For example, k1 for clothing made of cotton is 1, k1 for clothing made of chemical fiber is in the range of 0.6 to 1, k1 for clothing made of bulky material is in the range of 0.8 to 1.5, k1 for clothing made of down jacket is in the range of 0.4 to 0.8, and k1 for clothing made of windbreaker is in the range of 0.3 to 0.7.

[0087] In some embodiments, the first flushing time can also be calculated based on the weight of the clothes, the standard weight and the flushing time corresponding to the standard weight, for example, t1=WF1 / WF0*t0. The parameters can refer to the above description and will not be repeated here.

[0088] If the weight of the clothes is outside the preset range, or the weight of the clothes is not obtained, the first flushing time is selected according to the set weight. It is understandable that since the weight of the clothes exceeds the preset range, it cannot be calculated according to the above formula at this time, so the first flushing time can be selected according to the set weight. For example, a mapping table can be set, and a flushing time corresponding to a value exceeding the preset range and within the first range corresponds to a flushing time, and a value exceeding the preset range and within the second range corresponds to another flushing time, and so on. The first flushing time is determined by analogy.

[0089] The second method is to determine the flushing time of the drum cleaning according to the washing time of the main washing stage. For example, the washing time t3 of the main washing stage, the material of the clothes in the inner drum, the first coefficient k1 adjusted according to the material of the clothes, the second coefficient k2 adjusted according to the washing time of the main washing stage, and the flushing compensation time t4 can be obtained. The second flushing time t2 is calculated according to the washing time t3, the first coefficient k1, the second coefficient k2, and the flushing compensation time t4, for example, t2 = k1*k2*t3+t4. Among them, the washing time t3 of the main washing stage can be obtained according to the set program after the material of the clothes is determined. The first coefficient k1 and the second coefficient k2 are coefficients for time adjustment according to different parameters. For example, k1 for cotton clothes is 1, k1 for chemical fiber clothes is a value in the range of 0.6 to 1, k1 for large clothes is a value in the range of 0.8 to 1.5, k1 for down jackets is a value in the range of 0.4 to 0.8, and k1 for jackets is a value in the range of 0.3 to 0.7. For example, the value range of k2 can be 0.015 to 0.2. The greater the washing time t3, the greater the value of k2. The flushing compensation time t4 is a compensation value for the flushing time to fully clean the drum. For example, the value range of the flushing compensation time t4 is 30 seconds to 2 minutes. For example, when the weight of the clothes is greater, the value of the flushing compensation time t4 is greater.

[0090] The determination of the second flushing time is not limited to the above method. For example, the second flushing time can be calculated according to the washing time of the main washing stage, and the second flushing time is less than the washing time of the main washing stage, such as t2=k2*t3, or t2=k2*t3+t4. The selection of parameters can refer to the above description, which will not be repeated here. For another example, the second flushing time can be calculated according to the washing time of the main washing stage, the first coefficient and the second coefficient, that is, t2=k1*k2*t3. The selection of parameters can refer to the above description, which will not be repeated here.

[0091] The third method is to jointly determine the rinsing time of the drum cleaning according to the weight of the clothes and the washing time of the main washing stage. For example, the first rinsing time t1 calculated according to the weight of the clothes in the inner drum and the second rinsing time t2 calculated according to the washing time of the main washing stage are obtained, and the third rinsing time t6 is calculated according to the first rinsing time t1 and the second rinsing time t2. Wherein, b1 is a coefficient for adjusting the time according to the weight of the clothes, for example, the value range of b1 is 0.01 to 2, and the greater the weight of the clothes, the greater the value of b1. b2 is a coefficient for adjusting the time according to the washing time of the main washing stage, for example, the value range of b2 is 0.1 to 1.5, and the greater the washing time, the greater the value of b2. The third rinse time t6 can also be calculated using a linear equation.

[0092] In the embodiment of the present application, the rinsing time for drum cleaning is determined based on at least one of the weight of the clothes, the material of the clothes and the washing time of the main washing stage. The amount of fiber shed from the clothes can be determined more accurately, and a suitable rinsing time can be formulated based on the amount of fiber shed, thereby reducing the deposition of dirt and improving the cleaning effect of the drum.

[0093] 202. During the rinsing stage or after the rinsing stage is completed, the water level in the outer drum is controlled to reach a cleaning water level.

[0094] Exemplarily, the outer surface of the inner drum and the inner surface of the outer drum can be rinsed during the rinsing stage or after the rinsing stage is completed. It should be noted that the washing program may include a main washing stage, a rinsing stage, and a dehydration stage. The main washing stage is a stage for washing out impurities and dirt on the clothes. If the process of rinsing the outer surface of the inner drum and the inner surface of the outer drum is added in this stage, it is easy to cause the problem that the subsequent washing will still have dirt deposition and cannot be cleaned. The dehydration stage is a process in which the clothes have been processed and the clothes can be taken out or dried after the dehydration is completed. This stage is no longer suitable for water intake. Therefore, it is not suitable to put the rinsing of the outer surface of the inner drum and the inner surface of the outer drum into the dehydration stage. In summary, since the clothes are still in a state of high humidity during the rinsing stage or after the rinsing stage is completed, and the dirt on the clothes has been basically washed out, the drum can be cleaned in this process, which does not affect the processing state of the clothes and can clean the dirt washed out during the washing process.

[0095] The process of flushing the outer surface of the inner cylinder and the inner surface of the outer cylinder may be as follows: after the rinsing stage or after the rinsing stage is completed, the water level in the outer cylinder is controlled to reach the clean water level. The clean water level is the appropriate water level height for cleaning the outer cylinder and the inner cylinder. The water level height with the best cleanliness can be obtained through multiple experimental calibrations, or the water level height can be determined based on empirical values. For example, the clean water level can be greater than the water level height in the rinsing stage. At the clean water level, the inner cylinder is cleaned by driving the water flow to perform a cutting motion through the rotation of the inner cylinder.

[0096] 203. Rinse the outer surface of the inner cylinder and the inner surface of the outer cylinder according to the flushing time.

[0097] Flushing the outer surface of the inner cylinder and the inner surface of the outer cylinder can be achieved by driving the water flow under the rotation of the inner cylinder. It can be understood that the inner cylinder can be controlled to rotate, and the inner cylinder can drive the water flow to agitate between the inner cylinder and the outer cylinder to flush the outer surface of the inner cylinder and the inner surface of the outer cylinder. Under the clean water level, the inner cylinder is driven by the rotation of the inner cylinder to drive the water flow to perform a cutting motion to clean the cylinder.

[0098] The inner drum rotation speed may be a relatively high speed, such as a speed greater than or equal to 80 rpm. At this time, the centrifugal force exerted on the clothes is greater than their gravity, so that the clothes can be attached to the wall of the inner drum to prevent at least part of the water in the outer drum from entering the inner drum, thereby reducing the probability of dirt sticking to the clothes.

[0099] Exemplarily, the drum can be cleaned according to the flushing time calculated before washing. The flushing time may include the time consumed for water to enter the outer drum to reach the cleaning water level and the time for the inner drum to rotate. Different flushing times are configured for different amounts of dirt. This can improve the accuracy of dirt cleaning and thereby improve the cleaning effect.

[0100] In the control method of the washing machine provided in the embodiment of the present application, by rinsing the outer surface of the inner drum and the inner surface of the outer drum during each washing process instead of cleaning in a fixed cycle, the deposition of dirt can be reduced and the cleaning effect can be improved; and there is no need to set a separate drum cleaning program, which can simplify program design and reduce the impact on the washed clothes. In addition, the rinsing time for drum cleaning is determined based on at least one of the weight of the clothes, the material of the clothes, and the washing time of the main washing stage, which can improve the precise cleaning of deposited dirt, instead of using a uniform cleaning time for different dirt, which can improve the cleaning effect of dirt.

[0101] Among them, the flushing of the drum is set in the rinsing stage or after the rinsing is completed, and the flushing time may not occupy the additional time of the washing program, so that the drum can be cleaned without increasing the total time of the washing program, thereby improving the user experience.

[0102] For example, please combine Figure 1 and Figure 2 Also see Figure 3 , Figure 3 The third flow chart of the control method of the washing machine provided in the embodiment of the present application is shown in FIG. The control method of the washing machine provided in the embodiment of the present application is also provided, including:

[0103] 301. Before washing, determine a rinsing time for rinsing the outer surface of the inner drum and the inner surface of the outer drum according to at least one of the weight of the clothes in the inner drum, the material of the clothes, and the washing time of the main washing stage.

[0104] For the flushing time of the drum cleaning, the flushing time for flushing the outer surface of the inner drum and the inner surface of the outer drum can be determined according to at least one of the weight of the clothes in the inner drum, the material of the clothes, and the washing time of the main washing stage. It should be noted that the dirt between the inner drum and the outer drum is mainly formed by the deposition of fibers shed from the clothes, and the amount of fiber shedding corresponding to different weights of clothes is different; different clothing materials correspond to different washing mechanical forces, and the amount of fiber shedding corresponding to different washing mechanical forces is also different, such as the washing mechanical forces of cotton and linen washing and four-piece washing programs are different. When designing the washing program, the washing force is determined according to the material of the clothes; the washing time also determines the amount of fiber shedding. The longer the washing time, the greater the amount of fiber shedding. Therefore, the flushing time of the drum cleaning can be determined according to at least one of the weight of the clothes in the inner drum, the material of the clothes, and the washing time of the main washing stage.

[0105] Among them, the weight of the clothes, the material of the clothes, and the washing time of the main washing stage can all be determined before washing. For example, after putting the clothes into the inner drum, the clothes can be weighed to obtain the weight of the clothes. For another example, when the user selects a washing program such as cotton and linen washing or four-piece washing, or by setting a sensor such as camera shooting, the material of the clothes can be determined, and the washing time of the main washing program can be calculated according to the set program. Therefore, before washing starts, the rinsing time for rinsing the outer surface of the inner drum and the inner surface of the outer drum can be determined.

[0106] The determination of the flushing time may refer to the description of step 201 above, which will not be repeated here.

[0107] 302. Reduce the running time of the rinsing stage so that the sum of the reduced running time and the flushing time is greater than or equal to the original running time of the rinsing stage.

[0108] After the user selects a washing program, the working time of the washing program can be determined. For example, different washing programs correspond to different clothing materials, and different clothing weights correspond to different working times of washing programs. Thus, the working time of the washing program can be obtained according to the clothing material and clothing weight.

[0109] The washing program is a program for washing, rinsing and dehydrating clothes. For example, the washing program may include a main washing stage, a rinsing stage and a dehydrating stage. In the main washing stage, the inner drum rotates to disturb the water, which, combined with the detergent dissolved in the water, acts on the clothes to achieve cleaning of the clothes. The rinsing stage is the stage for removing detergent foam. The rinsing stage can be rinsed multiple times to continuously discharge the foam and reduce the foam residue on the clothes, which causes the illusion that the clothes are not washed clean. The dehydrating stage is the process of shaking out the water in the clothes.

[0110] In order to ensure that the rinsing time for rinsing the drum does not increase the total working time of the washing program, the running time of the rinsing stage can be reduced so that the sum of the reduced running time and the rinsing time is greater than or equal to the running time of the original rinsing stage. Since the rinsing stage is mainly for removing foam, and the reduction of the rinsing time does not affect the overall cleanliness of the clothes, the running time of the rinsing stage can be reduced. The working time of the main washing stage will affect the cleanliness of the clothes, so the rinsing time is not compensated by the working time of the main washing stage. Furthermore, the working time of the dehydration stage will affect the moisture content of the clothes, and if the moisture content of the clothes is too high, it will affect the drying time or the drying time. Therefore, the rinsing time is not compensated by the working time of the dehydration stage.

[0111] It should be noted that there may be multiple rinsing processes in the rinsing stage, and each rinsing process may include water intake, rinsing and drainage. Rinsing means controlling the rotation of the inner drum at a set water level to remove foam from the clothes.

[0112] Exemplarily, in at least the last rinsing process in the rinsing stage, the outer surface of the inner drum and the inner surface of the outer drum are rinsed, and the rinsing time of at least the last rinsing process is reduced, so that the sum of the reduced rinsing time and the rinsing time is equal to the rinsing time of the original rinsing process. In other words, by reducing the rinsing time of the rinse process in which the rinse is located, the rinsing time is compensated, so that the running time of the original rinsing stage remains unchanged, and therefore the working time of the entire washing program remains unchanged, the drum can be cleaned, and the washing time will not be increased, and the user will not have to wait longer for washing, thereby improving the user's use experience.

[0113] Exemplarily, after the rinsing stage is completed, the outer surface of the inner drum and the inner surface of the outer drum are rinsed for a rinsing time, and the rinsing time of at least one of the multiple rinsing processes in the rinsing stage is reduced, so that the sum of the reduced rinsing time and the rinsing time is equal to the rinsing time of the original rinsing process, thereby not affecting the running time of the rinsing stage, that is, not affecting the working time of the washing program. It is understandable that rinsing after rinsing is completed can compensate for the rinsing time by reducing the running time of the rinsing stage, so that the working time of the washing program remains unchanged. Similarly, the drum can be cleaned without increasing the washing time, and the user will not have to wait longer for washing, thereby improving the user's use experience.

[0114] In the control method of the washing machine provided in the embodiment of the present application, flushing is embedded in the rinsing stage or after the rinsing stage is completed, and the flushing time will not increase the working time of the washing program, so that the inner drum and the outer drum can be cleaned to improve the cleanliness without increasing the user's waiting time, thereby improving the user experience.

[0115] Among them, in order to improve the dirt removal effect, the cleaning water level in the outer cylinder can be dynamically balanced. Therefore, in the process of flushing the inner cylinder and the outer cylinder, the sewage can be continuously discharged, reducing the probability of dirt repeatedly deposited between the inner cylinder and the outer cylinder, which can further improve the cylinder cleaning effect.

[0116] Please combine Figures 1 to 3 Also see Figure 4 As shown, Figure 4 This is a fourth flow chart of the control method of a washing machine provided in an embodiment of the present application. This embodiment of the present application also provides a control method of a washing machine, comprising:

[0117] 401. Water is introduced into the inner cylinder, and water in the outer cylinder is discharged at the same time, so as to maintain the water level in the outer cylinder at a clean water level.

[0118] In the related art, the drum is usually cleaned at a clean water level, and the dirt deposited on the drum flows in the washing water, which may cause a risk of redepositing on the drum. Therefore, static cleaning of the drum at a clean water level has a poor cleaning effect.

[0119] In order to reduce the occurrence of the above phenomenon, the embodiment of the present application dynamically maintains the water level in the outer cylinder at a clean water level, so that the dirt deposited on the cylinder can be cleaned off on one side and the sewage containing dirt can be directly discharged on the other side, thereby improving the cleaning effect of the cylinder.

[0120] Exemplarily, water can be introduced into the inner drum, and the water in the outer drum can be discharged at the same time to maintain the water level in the outer drum at a clean water level. The introduction of water into the inner drum can be achieved by spraying water. It is understandable that a water inlet valve and a spray valve can be provided in the washing machine. When the water inlet valve is opened, water can be introduced into the outer drum, and when the spray valve is opened, water can be sprayed into the inner drum. For example, during the rinsing process, the spray port sprays water into the inner drum, which can remove at least part of the foam on the clothes to improve the foam removal rate. The embodiment of the present application adopts spraying water and water introduction at the same time. For example, the flow rate of the spraying water can be the same as the flow rate of the water introduction, so that the water in the inner drum and the water in the outer drum grow synchronously and stably, so as to reduce the phenomenon that the water with dirt in the outer drum flows into the inner drum, thereby reducing the secondary contamination of the clothes.

[0121] Among them, the water in the outer drum can be drained by pumping water to the drain outlet of the washing machine when the drain pump is turned on. Since the flow rate of the incoming water is less than the flow rate of the drain, the drain pump can be controlled to open and close to drain water at a set drainage sequence. For example, the drainage sequence of opening and closing the drain pump can be obtained. The setting of the drainage sequence can be obtained by the change of the water level. If the water level changes quickly, the drainage sequence can be accelerated, that is, the on-off ratio can be increased; if the water level changes slowly, the drainage sequence can be slowed down, that is, the on-off ratio can be reduced.

[0122] It should be noted that by optimizing the control timing of the drainage pump according to the combination of water level control and fixed timing, it is possible to avoid excessive water level fluctuations during high-speed rotation, which may cause the clean water level to be too low or too high and affect the flushing effect.

[0123] 402. Control the inner drum to rotate at a first speed so that the clothes adhere to the inner drum and drive the water flow to agitate between the inner drum and the outer drum to wash the outer surface of the inner drum and the inner surface of the outer drum.

[0124] In the above process of maintaining the dynamic balance of the cleaning water level, the inner drum can be controlled to rotate at a higher speed such as the first speed at the same time. The first speed can be a speed greater than or equal to 80rpm, so that the clothes adhere to the wall of the inner drum and drive the water flow between the inner drum and the outer drum to rinse the outer surface of the inner drum and the inner surface of the outer drum.

[0125] Flushing the outer surface of the inner cylinder and the inner surface of the outer cylinder can be achieved by driving the water flow under the rotation of the inner cylinder. It can be understood that the inner cylinder can be controlled to rotate, and the inner cylinder can drive the water flow to agitate between the inner cylinder and the outer cylinder to flush the outer surface of the inner cylinder and the inner surface of the outer cylinder. Under the clean water level, the inner cylinder is driven by the rotation of the inner cylinder to drive the water flow to perform a cutting motion to clean the cylinder.

[0126] The inner drum rotation speed may be a relatively high speed, such as a speed greater than or equal to 80 rpm. At this time, the centrifugal force exerted on the clothes is greater than their gravity, so that the clothes can be attached to the wall of the inner drum to prevent at least part of the water in the outer drum from entering the inner drum, thereby reducing the probability of dirt sticking to the clothes.

[0127] In the control method of the washing machine provided in the embodiment of the present application, a flushing control scheme for flushing the outer surface of the inner drum and the inner surface of the outer drum is set in each washing program, wherein the flushing control scheme includes a control scheme of using live water to inlet, rotating the inner drum at high speed, and coordinating the start and stop sequence of the drainage pump to realize clean water flushing and sewage discharge, which can improve the effect of drum cleaning. In addition, at least one of the weight of the clothes, the material of the clothes, and the washing time of the main washing stage is used to determine the flushing time of the drum cleaning, that is, the flushing time is determined according to the amount of fiber shedding, rather than using a fixed flushing time for flushing, which can improve the effect of removing dirt.

[0128] In order to better implement the control method of the washing machine in the embodiment of the present application, the embodiment of the present application also provides a control device for the washing machine. Figure 5 and Figure 6 , Figure 5 This is a first structural schematic diagram of a control device for a washing machine provided in an embodiment of the present application, Figure 6 A second structural schematic diagram of a control device for a washing machine provided in an embodiment of the present application. The control device 500 of the washing machine includes a control unit 501, a flushing unit 502 and a determination unit 503. Among them, the washing machine can be a drum washing machine or a pulsator washing machine, and the washing machine includes an inner drum and an outer drum sleeved outside the inner drum, the inner drum and the outer drum are coaxially arranged, and the inner drum can rotate relative to the outer drum. The inner drum is used to carry clothes, and the outer drum is used to hold washing water. For example, the inner drum can be provided with a water hole, and the water in the outer drum enters the inner drum through the water hole of the inner drum. With the rotation of the inner drum and the cooperation of the laundry liquid, the washing of clothes is achieved. The washing machine is not limited to the above-mentioned parts. For example, the washing machine may also include a housing, a display panel, a motor, a rotating shaft and other components, which are not described here.

[0129] The control unit 501 is used to control the water level in the outer tub to reach the cleaning water level during or after the rinsing stage;

[0130] The flushing unit 502 is used to control the rotation of the inner cylinder to drive the water flow to agitate between the inner cylinder and the outer cylinder to flush the outer surface of the inner cylinder and the inner surface of the outer cylinder;

[0131] The determination unit 503 is used to determine the rinsing time for rinsing the outer surface of the inner drum and the inner surface of the outer drum before washing according to at least one of the weight of the clothes in the inner drum, the material of the clothes and the washing time of the main washing stage.

[0132] All of the above technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described in detail here.

[0133] As can be seen from the above, in the control device 500 of the washing machine provided in the embodiment of the present application, by rinsing the outer surface of the inner drum and the inner surface of the outer drum during each washing process instead of cleaning in a fixed cycle, the deposition of dirt can be reduced and the cleaning effect can be improved; and there is no need to set a separate drum cleaning program, which can simplify program design and reduce the impact on the washed clothes. In addition, the rinsing time for drum cleaning is determined based on at least one of the weight of the clothes, the material of the clothes, and the washing time of the main washing stage, which can improve the precise cleaning of deposited dirt, rather than using a uniform cleaning time for different dirt, which can improve the cleaning effect of dirt.

[0134] Accordingly, the embodiment of the present application also provides a washing machine, which may be a drum type washing machine or a pulsator type washing machine.

The washing machine 600 may further include a water inlet valve, a water inlet pipe, a spray valve, a spray pipe and a drainage pump. The water inlet valve controls the on-off of water inlet. The water inlet pipe is connected to a water source. When the water inlet valve is opened, water enters the outer drum 602 through the water inlet pipe. The spray valve controls the on-off of spray water. When the spray valve is opened, water is sprayed into the inner drum 601 through the spray pipe. The drainage pump controls the on-off of drainage. When the drainage pump is turned on, the water in the outer drum 602 can be discharged. The washing machine 600 is not limited to the above-mentioned parts. For example, the washing machine 600 may also include a housing, a display panel, a motor, a rotating shaft and other parts (not shown in the figure), which are not specifically limited here.
