[0002] In existing washing machines, after executing the washing process, a rinsing process is generally required to be performed to remove additives and other substances remaining on the clothes during the washing process using the rinsing water flow.

[0003] In the related art, a rinsing method of spraying water inlet and draining water simultaneously is proposed, but in this method, the drainage volume may be less than the water intake volume, resulting in overflow. Summary of the invention

[0056] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described 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, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0057] It should be understood that the "plurality" mentioned in this article refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and so on are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and so on do not limit the quantity and execution order, and the words "first", "second" and so on do not limit certain different

[0058] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0059] The existing rinsing program generally starts by filling the washing machine drum with water to a set rinsing water level, controlling the inner drum to run at a set start-stop ratio, and using the stored water in the washing machine drum to rinse the clothes. Since the stored water is used to rinse clothes, additives in the rinsing water may come into contact with the clothes again, affecting the rinsing effect. Especially in the later stages of rinsing, most of the additives and other substances on the clothes have been mixed into the rinsing water, causing the already clean clothes to absorb the additives again. To address this issue, a rinsing method that combines spraying water intake and drainage at the same time has been proposed on the market, but this method may result in a situation where the drainage volume is less than the water intake volume, posing a risk of overflow.

[0060] In order to solve the above technical problems, this embodiment proposes a spray rinsing method, which includes:

[0061] Before spraying and rinsing the clothes, the washing machine is controlled to be in a draining state and the inner drum is controlled to rotate;

[0062] When the inner drum is running stably at the target speed, the spray device is controlled to spray and rinse the clothes;

[0063] When the inner drum is running stably at a target speed, obtaining a first motor parameter before spraying and rinsing and a second motor parameter during spraying and rinsing;

[0064] The inner drum speed during the spray rinsing process is regulated according to the first motor parameter and the second motor parameter.

[0065] In this embodiment, by controlling the drainage and spraying to work synchronously during the spray rinsing process, it is ensured that the drainage and spraying can be carried out in a coordinated manner during the spray rinsing process. In addition, during the spraying process, the system will monitor the second motor parameters of the inner drum in real time when it is in the target speed state, and dynamically adjust the speed of the inner drum of the washing machine in combination with the first motor parameters of the inner drum in the target speed state before spraying. This timely adjustment mechanism can effectively prevent the washing machine from overflowing during the spray rinsing of clothes, thereby ensuring the normal operation of the washing machine and the safety of the user. Through this sophisticated control method, the washing machine can maintain the best washing effect during the rinsing process, while avoiding the potential risks and inconveniences caused by overflowing.

[0066] Furthermore, in the process of spray rinsing, the present embodiment also monitors the real-time water level and real-time water flow rate in the process of spray rinsing in real time, and combines these data with the initial water level before spray rinsing to intelligently control the spray state of the spray device, ensuring that the water level in the outer drum is always kept within a safe range. This precise control mechanism can effectively prevent the washing machine from overflowing during use, thereby ensuring the safe operation of the washing machine. In this way, users can enjoy a more secure and convenient laundry experience, further improving user satisfaction.

[0067] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following embodiments and examples can be combined with each other if there is no conflict.

[0068] First, the application subject of the spray rinsing method of this embodiment is introduced. The application subject of the spray rinsing method of this embodiment is a washing machine, and the washing machine of this embodiment can have only a washing function, or can have both a washing function and a drying function. The structural form of the washing machine can be a drum type washing machine, a pulsator type washing machine, or a wall-mounted washing machine.

[0069] Reference Figure 1 The structural schematic diagram of a washing machine is shown in FIG. 1 , wherein the washing machine comprises a housing 1, an outer drum 3 and an inner drum 2. The outer drum 3 is arranged in the housing 1, and the inner drum 2 is rotatably arranged in the outer drum 3. The wall of the inner drum 2 is provided with a flow hole, and the washing water can flow between the outer drum 3 and the inner drum 2 through the flow hole. A drain port is provided at the bottom of the outer drum 3, and the drain port is connected to a drain pipe 9. The drain port can be provided with a drain valve that can open and close the drain port, and when the drain valve opens the drain port, the water in the outer drum 3 can be discharged from the washing machine through the drain pipe 9. In other achievable methods, the drain port can also be set to be normally open, and a drain pump 10 can be set in the flow path between the drain pipe 9 and the drain port. When the drain pump 10 is started, the water in the outer drum 3 is pumped into the drain pipe 9 and discharged from the washing machine.

[0070] The washing machine further comprises a water level detection device, which is arranged in the outer drum 3 and is used to detect the water level of the outer drum 3 .

[0071] A driving motor 4 is provided in the area between the outer tub 3 and the housing 1, and the power output end of the driving motor 4 is connected to the bottom of the inner tub 2 through the driving shaft 11 via the bottom of the outer tub 3. When the driving motor 4 is started, the driving shaft 11 is started to rotate, and the rotation of the driving shaft 11 drives the inner tub 2 to rotate. In the washing program and the rinsing program, the driving motor 4 can also control the forward and reverse rotation of the inner tub 2 according to the preset rotation-stop ratio of the program.

[0072] The washing machine further includes a water inlet pipe 5, a water inlet valve 6 and a spray device 7. One end of the water inlet pipe 5 is connected to the user's tap, and the other end is connected to the water inlet end of the spray device 7. The water inlet valve 6 is arranged on the water inlet pipe 5 to control the on-off of the water path of the water inlet pipe 5. The water inlet pipe 5 is also provided with a flow meter to detect the water flow rate of the water inlet pipe 5. When the water inlet valve 6 opens the water inlet pipe 5, the water in the water inlet pipe 5 enters the spray device 7 and sprays the clothes through the spray device 7.

[0073] The spray device 7 is preferably arranged above the door body 8, and the spray direction of the spray device 7 is toward the drum. When the spray device 7 sprays the clothes, the spray water can cover the axial area of ​​the inner drum 2 of the washing machine, and the spray water column forms a water curtain with a certain width. During the spray rinsing process, after the clothes are close to the drum wall, they can be sprayed and rinsed by the water curtain once every turn. Under the action of centrifugal force, the spray water flow penetrates the clothes attached to the wall, takes away the residual detergent, and discharges it through the drain port.

[0074] The above is an exemplary introduction to the implementation subject of the embodiment of the present application. Now, in combination with the above implementation subject or a similar implementation subject, the spray rinsing method of the embodiment of the present application is introduced in detail.

[0075] Reference Figure 2 The spray rinsing process flow chart of the present embodiment comprises the following steps:

[0076] S21. Before spraying and rinsing the clothes, the washing machine is controlled to be in a draining state and the inner drum is controlled to rotate.

[0077] Specifically, before starting to spray and rinse the clothes, you first need to make sure that the washing machine is in a draining state. This step can be achieved by opening the drain valve of the washing machine, or by starting the built-in drain pump of the washing machine. Regardless of which method is chosen, the purpose is to allow the water in the washing machine to be drained smoothly, thereby preparing for the next step of spray rinsing. After the washing machine is in a draining state, it is necessary to control the rotation of the inner drum of the washing machine. Specifically, it is necessary to gradually increase the speed of the inner drum until it reaches the target speed required to start the spray device. When the speed of the inner drum reaches the target speed, the spray device can achieve a better spray rinsing effect on the clothes.

[0078] S22. When the inner drum is running stably at the target speed, the spray device is controlled to spray and rinse the clothes.

[0079] Specifically, after the speed of the inner drum of the washing machine reaches the preset target speed, the control system will start the spray device to spray and rinse the clothes. The spray device located above the washing machine door sprays into the drum, which can cover the axial area of ​​the inner drum of the washing machine. The spraying water column forms a water curtain with a certain width. After the clothes are close to the wall of the drum, they can be sprayed and rinsed by the water curtain once every turn. Under the action of centrifugal force, the spraying water flow penetrates the clothes attached to the wall, takes away the residual detergent, and discharges it through the drain port.

[0080] During the entire spray rinsing process, the inner drum will continue to rotate, which can ensure that the clothes are always in motion during the rinsing process, thereby achieving a full range of spray effects. This combination of continuous rotation and spraying not only improves the rinsing efficiency, but also ensures that the clothes are cleaner and fresher after rinsing.

[0081] In a preferred embodiment, after the rotation speed of the inner drum reaches the target rotation speed and maintains the set rotation time t, the spray device is controlled to spray and rinse the clothes. The set rotation time t is, for example, 5s-10s.

[0082] S23. When the inner drum is running stably at the target speed, obtain the first motor parameter before the spray rinsing and the second motor parameter during the spray rinsing.

[0083] Specifically, the first motor parameters are obtained when the inner drum is running stably at the target speed before spraying and rinsing, because when there is no water inflow, there will be no overflow, thus ensuring the accuracy of the judgment result. In order to obtain more accurate and reliable first motor parameters, the motor parameters can be periodically collected when the inner drum speed reaches the target speed and during the period of maintaining this set rotation length, and the average value of the collected multiple motor parameters is used as the first motor parameter.

[0084] During the spray rinsing process, the second motor parameters when the inner drum is running at the target speed can be obtained through real-time monitoring or periodic detection. If the water is not drained smoothly during the spraying process, the water will rotate with the inner drum together with the clothes in the drum. As the water intake continues to increase, the total weight in the drum will gradually increase, causing the motor parameter value to increase accordingly. Therefore, the second motor parameters and the second motor parameters can be used to determine whether the washing machine has a risk of overflow.

[0085] The motor parameters include but are not limited to motor power, motor current and motor voltage.

[0086] S24, regulating the speed of the inner drum during the spray rinsing process according to the first motor parameter and the second motor parameter.

[0087] Specifically, after determining the first motor parameter and the second motor parameter, the drainage condition of the washing machine can be effectively determined by analyzing the first motor parameter and the second motor parameter. If the drainage is not smooth, it can be determined whether the washing machine has a risk of overflow. Once the risk of overflow is detected, the rotation speed of the inner drum can be adjusted accordingly in time to prevent water from overflowing the washing machine, thereby ensuring the normal operation of the washing machine and the safety of the user.

[0088] In some embodiments, the spray rinsing method includes: before performing spray rinsing, determining the rinsing gear to be executed according to the properties of the clothes, wherein the rinsing gear includes rinsing parameters, and different rinsing gears correspond to at least different rinsing parameters; the rinsing parameters include at least a target speed.

[0089] Specifically, the washing machine of this embodiment has a plurality of different rinsing gears, each of which corresponds to a set of specific rinsing parameters, which ensure the efficiency and pertinence of the rinsing process. The rinsing parameters mainly include the target speed, which is the speed of the inner drum that the washing machine needs to reach when the spray device starts spraying. In addition, in other achievable ways, the rinsing parameters may also include the spray water flow rate, that is, the amount of water sprayed onto the clothes per unit time during the spray rinsing process.

[0090] The selection of the rinsing gear is closely related to the properties of the clothes. An example of clothing properties is the dry weight of the clothes in a dry state, which helps the washing machine determine the total volume and total water absorption of the clothes during the spray rinsing process. In other achievable ways, the clothing properties may also include the material of the clothes, because clothes of different materials have different water absorption. Before the clothes are spray rinsed, it is necessary to determine the rinsing gear to be executed according to the properties of the clothes, and then determine the corresponding rinsing parameters according to the determined rinsing gear.

[0091] During the spraying process, water will first pass through the clothes and then be drained away under the action of centrifugal force. The weight of different clothes will absorb water differently. Therefore, when there are more clothes, the water absorption effect is also stronger, which may cause the drainage volume to be less than the spraying water intake, thus causing overflow.

[0092] In a preferred embodiment, the clothing attributes include dry clothes weight, and the rinsing level to be executed is determined according to the clothing attributes, including: determining the rinsing level corresponding to the current dry clothes weight according to a preset correspondence between the dry clothes weight and the rinsing level; wherein: different dry clothes weight intervals correspond to different rinsing levels, and the higher the dry clothes weight, the larger the value of the rinsing parameter of the rinsing level corresponding to the dry clothes weight interval.

[0093] In other achievable ways, the laundry attributes include the weight of dry laundry and the material of the laundry. If the laundry is heavy and absorbent, a gear with a high target speed and a large spray water flow rate can be matched. During the spray rinsing process, the washing machine will operate according to these determined rinsing parameters to ensure the best rinsing effect while reducing the risk of overflow.

[0094] In some embodiments, reference Figure 3 The spray rinsing flow chart of FIG. 1 is a flow chart for adjusting the speed of the inner drum during the spray rinsing process according to the first motor parameter and the second motor parameter, and includes the following steps:

[0095] S31, determining a difference between a second motor parameter and the first motor parameter;

[0096] S32. When the difference between the second motor parameter and the first motor parameter reaches the overflow determination threshold, the inner drum speed is reduced; when the difference between the second motor parameter and the first motor parameter does not reach the overflow determination threshold, the inner drum speed is maintained until the set spraying time is reached.

[0097] Specifically, after determining the first motor parameter and the second motor parameter, it can be determined whether the washing machine has a risk of overflow by comparing the difference between the second motor parameter and the first motor parameter.

[0098] If the difference between the second motor parameter and the first motor parameter reaches the set overflow determination threshold, then it can be determined that the washing machine is at risk of overflow. In this case, measures need to be taken to reduce the speed of the inner drum to eliminate the risk of overflow. On the contrary, if the difference between the second motor parameter and the first motor parameter does not reach the overflow determination threshold, then it can be considered that the washing machine is not at risk of overflow, and the speed of the inner drum can be maintained until the set spraying time is reached.

[0099] Furthermore, after adjusting the speed of the inner drum, the inner drum will rotate at the adjusted speed. When the inner drum is running stably at the adjusted speed, the second motor parameters are reacquired. Then, based on the difference between the newly acquired second motor parameters and the first motor parameters, it is determined whether the washing machine is at risk of overflow. If the difference between the newly acquired second motor parameters and the first motor parameters still reaches the overflow judgment threshold, it means that the washing machine is still at risk of overflow, and the speed of the inner drum needs to be further reduced. This process will be repeated until the difference between the newly acquired second motor parameters and the first motor parameters does not reach the overflow judgment threshold. At this time, the speed of the inner drum can be maintained until the set spray time is reached.

[0100] The reduction value of the inner drum speed may be a fixed value or a gradually decreasing value. For example, the current reduction value of the inner drum speed is V1, and the next reduction value of the inner drum speed is V2, where V1>V2.

[0101] The overflow determination threshold of this embodiment is a critical value for determining whether the washing machine has a risk of overflow. The overflow determination threshold is set according to the specific performance of the washing machine and experimental data to ensure that it can accurately determine whether there is a risk of overflow during actual use. The overflow scheduling threshold can be a fixed value or can be different according to different rinsing gears.

[0102] In one example, the rinsing parameters also include an overflow determination threshold, and different rinsing gears correspond to different overflow determination thresholds, and the higher the dry clothes weight, the larger the overflow determination threshold of the rinsing gear corresponding to the dry clothes weight interval. Specifically, different rinsing gears correspond to different overflow determination thresholds to ensure that the overflow risk of the washing machine can be accurately judged in different situations. For example, when the dry clothes weight of the clothes is high, the system will automatically select a rinsing gear with a higher dry clothes weight interval, and the overflow determination threshold of this gear will be set higher accordingly. The purpose of this is to prevent overflow during the rinsing process and to ensure that the washing machine can be safer and more efficient when handling heavier clothes.

[0103] In some embodiments, reference Figure 4 The spray rinsing process flow chart of FIG. 1 further includes the following steps:

[0104] S41, before spray rinsing, obtaining the initial water level of the outer drum;

[0105] S42, during the spray rinsing process, obtaining the real-time water flow rate of the spray device and the real-time water level of the outer drum;

[0106] S43, controlling the opening state of the spray device according to the initial water level, the real-time water inflow rate and the real-time water level.

[0107] Specifically, before the spray device is turned on to spray and rinse the clothes, the washing machine has gone through the conventional washing stage and washing and dehydration stage. At this time, a small amount of water may remain at the bottom of the outer drum of the washing machine. In order to ensure the accuracy of the drainage data judgment, it is necessary to detect the initial water level in the outer drum through the water level detection device before the spray device is turned on to spray and rinse the clothes.

[0108] During the spray rinsing process of the clothes, the water inlet flow of the spray device and the real-time water level of the outer drum are monitored in real time or periodically. In this way, it is possible to further judge whether the washing machine has a risk of overflowing based on the initial water level, the real-time water inlet flow and the real-time water level. If it is judged that the washing machine has a risk of overflowing, the spraying state of the spray device can be controlled in time, thereby further effectively avoiding the risk of overflowing of the washing machine, ensuring the normal operation of the washing machine, and avoiding potential losses and safety hazards caused by overflowing.

[0109] In one example, refer to Figure 5 The spray rinsing flow chart includes the following steps to control the spray state of the spray device according to the initial water level, the real-time water flow rate and the real-time water level:

[0110] S51. Determine the overflow calibration value according to the initial water level and the real-time water inlet flow rate. The overflow calibration value satisfies the formula: X=FS.

[0111] S52, determining the difference between the real-time water inflow rate and the real-time water level: F-S1;

[0112] S53, when the difference between the real-time water inflow rate and the real-time water level satisfies: F-S1≤K*X, control the spraying device to stop spraying; when the difference between the real-time water inflow rate and the real-time water level satisfies: F-S1>K*X, maintain the spraying state of the spraying device;

[0113] Where: X is the overflow calibration value, F is the real-time water inlet flow, S is the initial water level, S1 is the real-time water level, K is the overflow coefficient, 0<K<1.

[0114] Specifically, the F value represents the water flow rate of the spray device, while the S1 value represents the real-time water level in the outer drum. The difference between F and S1 actually reflects the drainage volume of the washing machine. Since the F value is relatively fixed in most cases, the larger the drainage volume, the smaller the S1 value, which means that the more water is discharged, the less likely it is to overflow. On the contrary, if the drainage volume is small, the S1 value will increase, which indicates that the washing machine is more likely to overflow.

[0115] In addition, S represents the initial water level, which is also a fixed value. Therefore, the difference of FS is also a fixed value, and this difference is used as the overflow calibration value X. Then the washing machine's drainage volume F-S1 is compared with the product of the overflow coefficient K and the overflow calibration value X to determine whether the washing machine is at risk of overflow, and the spraying state of the spray device is controlled accordingly. In the case of F-S1>K*X, it means that the washing machine has a large drainage volume and there is no risk of overflow. The spraying state of the spray device is maintained until the set spraying time is reached. In the case of F-S1≤K*X, it means that the washing machine has a small drainage volume and there is a risk of overflow. At this time, the spray device is controlled to stop spraying.

[0116] Furthermore, after the step of stopping the spraying device, the difference between the real-time water inflow rate and the real-time water level needs to be re-determined. When the difference between the re-determined real-time water inflow rate and the real-time water level still satisfies: F-S1≤K*X, the spraying device is kept in the stopped spraying state; when the difference between the real-time water inflow rate and the real-time water level satisfies: F-S1>K*X, the spraying state of the spraying device is restored, thereby ensuring the safe use of the washing machine.

[0117] The overflow coefficient is set according to the specific performance and experimental data of the washing machine to ensure that it can accurately determine whether there is a risk of overflow during actual use. The overflow coefficient can be a fixed value or it can vary according to different rinsing gears. In one example, the rinsing parameters also include the overflow coefficient, and different rinsing gears correspond to different overflow coefficients, and the higher the dry clothes weight, the greater the overflow coefficient of the rinsing gear corresponding to the dry clothes weight interval.

[0118] In general, this embodiment determines whether the washing machine has a risk of overflow by measuring the changes in motor parameters during the rotation of the inner drum before and after spray rinsing, and reduces the inner drum speed to eliminate the risk of overflow when the washing machine has a risk of overflow. In addition, this embodiment further determines the drainage volume of the washing machine based on the water level in the outer drum and the spray water inlet flow rate, so as to further determine the risk of overflow based on the drainage volume, and controls the spray device to stop spraying when the washing machine has a risk of overflow, so as to effectively avoid the occurrence of overflow when the inner drum speed is reduced to the minimum speed and still cannot eliminate the risk of overflow. In addition, this embodiment also determines the rinsing gear according to the weight of the clothes, so as to implement different spray rinsing controls for clothes of different weights, and effectively avoids the occurrence of overflow during the spray rinsing process of clothes of different weights.

[0119] In the above-mentioned embodiments of the present application, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. The steps shown in the relevant flow chart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of steps described in the foregoing embodiments is only an example, and it is also within the scope of protection of the embodiments of the present application to reasonably adjust the order of steps based on the content of the embodiments of the present application.

[0120] The spray rinsing method of the embodiment of the present application is described in detail below with reference to a specific example. The spray rinsing method includes the following processing steps:

[0121] like Figure 6As shown in the flowchart, the clothes are weighed by the rotation of the driving motor before the washing water enters. According to the weight level, the first spray level or the second spray level is executed. The weight of the clothes is divided into L1, L2, L3, and L4 weight levels in the washing machine program, where L1 corresponds to very little clothes, L2 corresponds to a small amount of clothes, L3 corresponds to medium clothes, and L4 corresponds to a large amount of clothes.

[0122] If the actual weight of the clothes corresponds to weight levels L1 and L2, the first level of spraying is performed during the spraying and rinsing process, and the corresponding inner drum speed in the first level of spraying is V1. After entering the spraying and rinsing stage with a total spraying time of T, before the spraying device sprays and rinses the clothes, the inner drum is controlled to rotate first, and after the speed reaches V1 and stabilizes for t1 time, the spraying device is controlled to spray the clothes.

[0123] If the actual weight of the clothes corresponds to weight levels L3 and L4, the second-speed spraying is performed during the spraying and rinsing process, and the corresponding inner drum speed in the second-speed spraying is V2. After entering the spraying and rinsing stage with a total spraying time of T, before the spraying device sprays and rinses the clothes, the inner drum is controlled to rotate first, and after the speed reaches V2 and stabilizes for t1 time, the spraying device is controlled to spray the clothes.

[0124] Among them, T is 3min~5min, V1 is 150rpm~200rpm, V2 is 300rpm~400rpm, and t1 is 5s~10s.

[0125] At the same time, when executing the spray rinsing stage, the motor power value is collected in real time. Before the spray device sprays the clothes, within the t1 time after the inner drum speed stabilizes, a power value is collected every second, and the average value W1 is taken; after the spray device sprays the clothes, a power value W2 is collected every second.

[0126] If the first gear spray is executed, when W2-W1≥m1, it is judged that there is a risk of overflow, and protection treatment is performed: after the speed V1 drops by 50prm, it is maintained for t2 (t2 is 5s-10s). During t2, the power per second is collected and the average value W3 is taken. When W3-W1≥m1, V1 continues to drop by 50rpm and maintains t2, and the power per second is collected and the average value is taken. Repeat the above operation until W3-W1<m1, and maintain this speed until the total spraying time T is completed. Among them, m1 is 150W-250W.

[0127] If the second-speed spray is executed, when W2-W1≥m2, it is judged that there is a risk of overflow, and protection treatment is performed: after the speed V2 drops by 50prm, it is maintained for t2 (t2 is 5s-10s). During t2, the power per second is collected and the average value W3 is taken. When W3-W1≥m2, V2 continues to drop by 50rpm and maintains t2, and the power per second is collected and the average value is taken. Repeat the above operation until W3-W1<m2, and maintain this speed until the spraying time T is completed. Among them, m2 is 250W-350W.

[0128] Further, such as Figure 7 As shown in the flowchart, when the spray device is turned on to spray the clothes, the real-time spray flow F is also recorded, and the initial water level S in the outer drum before the spray is turned on is recorded, and the overflow calibration value X=FS is obtained, where the F value is the real-time spray flow rate and the S value is the initial water level, which is a fixed value. During the spray device spraying and rinsing the clothes, the real-time water level S1 in the outer drum is synchronously recorded.

[0129] During the period when the spray device sprays and rinses the clothes, when the washing machine is performing the first-speed spraying, if F-S1≤0.3X, it is determined that there is a risk of overflow; when the second-speed spraying is performed, if F-S1≤0.6X, it is determined that there is a risk of overflow. At this time, the spray device is controlled to stop spraying, while keeping the inner drum speed unchanged, and when F-S1>0.3X or F-S1>0.6X, the spray device is controlled to spray the clothes again.
