Description

Technical Field

[0001] The present invention relates to the technical field of washing machines, and in particular to a spray rinsing method for a washing machine, an electronic device, and a washing machine. Background Art

[0002] In conventional washing machines, a rinse cycle is generally required after the wash cycle to remove additives and other substances remaining on the clothes during the wash cycle using the rinse water. However, the conventional rinse cycle generally uses the water stored in the drum to rinse the clothes, and the detergent will be adsorbed on the clothes again.

[0003] In the related art, a rinsing method of spraying water and draining water simultaneously is proposed, but this method may cause the drainage volume to 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 present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0057] It should be understood that the “plurality” mentioned herein refers to two or more than two. 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 merely 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 a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as “first” and “second” are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art can understand that words such as “first” and “second” do not limit the quantity and execution order, and words such as “first” and “second” do not limit certain different

[0058] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion. 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 expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0059] The existing rinsing process generally involves filling the washing machine drum with water to a set rinse 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 rinse 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 rinse water, causing the already clean clothes to absorb the additives again. To address this issue, a rinsing method that simultaneously sprays water in and out has been proposed on the market. However, 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 stably running 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 synchronization of drainage and spraying during the spray-rinsing process, drainage and spraying are ensured to proceed in a coordinated and consistent manner. Furthermore, during the spraying process, the system monitors the parameters of the second motor in real time when the inner drum is at the target speed. This dynamic adjustment of the inner drum speed is based on the parameters of the first motor, which was at the target speed before the spraying process. This timely adjustment mechanism effectively prevents overflow during the spray-rinsing process, thereby ensuring the normal operation of the washing machine and user safety. This sophisticated control method allows the washing machine to maintain optimal washing results during the rinsing process while avoiding the potential risks and inconveniences caused by overflow.

[0066] Furthermore, this embodiment monitors the real-time water level and inflow rate during the spray-rinsing process. This data is combined with the initial water level before the spray-rinsing process to intelligently control the spraying state of the spray device, ensuring that the water level in the outer drum remains within a safe range. This precise control mechanism effectively prevents overflow 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 with reference to the accompanying drawings. The following embodiments and examples may be combined with each other unless there is any 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. The washing machine of this embodiment can have only a washing function or can have both a washing function and a drying function. The structure of the washing machine can be a drum washing machine, a pulsator washing machine, or a wall-mounted washing machine.

[0069] Reference Figure 1 Schematic diagram of the structure of a washing machine, the washing machine includes 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 outlet is provided at the bottom of the outer drum 3, and the drain outlet is connected to the drain pipe 9. A drain valve that can open and close the drain outlet can be provided at the drain outlet. When the drain valve opens the drain outlet, the water in the outer drum 3 is discharged from the washing machine through the drain pipe 9. In other feasible embodiments, the drain outlet can also be set to be normally open, and a drain pump 10 can be provided in the flow path between the drain pipe 9 and the drain outlet. 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 drive motor 4 is installed between the outer drum 3 and the housing 1. The power output of the drive motor 4 is connected to the bottom of the inner drum 2 via a drive shaft 11, which passes through the bottom of the outer drum 3. When the drive motor 4 is turned on, the drive shaft 11 rotates, which in turn drives the inner drum 2. During the wash and rinse cycles, the drive motor 4 also controls the forward and reverse rotation of the inner drum 2 according to a preset start-stop ratio.

[0072] The washing machine also 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 of the spray device 7. The water inlet valve 6 is installed on the water inlet pipe 5 to control the flow of water through the water inlet pipe 5. The water inlet pipe 5 is also equipped with a flow meter to detect the flow rate of water entering 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 is sprayed on the clothes by the spray device 7.

[0073] The spray device 7 is preferably positioned above the door 8, with the spray direction of the spray device 7 directed toward the interior of the drum. When the spray device 7 sprays the clothes, the spray water covers the axial area of ​​the washing machine's inner drum 2, forming a water curtain with a certain width. During the spray rinse process, the clothes, once they are close to the drum wall, are rinsed by the water curtain with each rotation. The spray water, under the action of centrifugal force, penetrates the clothes adhering to the wall, removes any residual detergent, and discharges it through the drain outlet.

[0074] The above is an illustrative introduction to the implementation subject of the embodiment of the present application. Now, in combination with the above implementation subject or 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 method of this embodiment includes the following steps:

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

[0077] Specifically, before beginning the spray rinse, ensure the washing machine is draining. This can be done by opening the drain valve or by activating the built-in drain pump. Regardless of the method, the goal is to drain the water smoothly, preparing for the next step of the spray rinse. Once the washing machine is draining, the rotation of the inner drum must be controlled. Specifically, the speed of the inner drum must be gradually increased until it reaches the target speed required to activate the spray mechanism. When the inner drum speed reaches the target speed, the spray mechanism can achieve optimal spray rinsing results for the clothes.

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

[0079] Specifically, after the washing machine's inner drum speed reaches a preset target speed, the control system activates the spray device to spray and rinse the clothes. The spray device, located above the washing machine door, sprays water into the drum, covering the axial area of ​​the washing machine's inner drum. The spraying water forms a water curtain with a certain width. As the clothes cling to the drum wall, they are rinsed by the water curtain with each rotation. The spraying water, driven by centrifugal force, penetrates the clothes adhering to the wall, carrying away any residual detergent and draining them out through the drain.

[0080] During the entire spray rinsing process, the inner drum will continue to rotate, ensuring that the clothes are always in motion during the rinsing process, thus 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 stably running at the target speed, obtain the first motor parameters before the spray rinsing and the second motor parameters during the spray rinsing.

[0083] Specifically, the first motor parameters are obtained while the inner drum is operating stably at the target speed before spray rinsing. This ensures the accuracy of the determination because, without water ingress, there will be no overflow. To obtain more accurate and reliable first motor parameters, the motor parameters can be periodically collected while the inner drum reaches the target speed and maintains this rotation for a set period of time. The average of these multiple collected motor parameters is then used as the first motor parameter.

[0084] During the spray and rinse process, the second motor parameters can be obtained through real-time monitoring or periodic testing when the inner drum is running at the target speed. If drainage is not smooth during the spray process, the water and the clothes in the drum will rotate with the inner 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 is at risk of overflow.

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

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

[0087] Specifically, after determining the first and second motor parameters, the first and second motor parameters are analyzed to effectively determine the drainage condition of the washing machine. If drainage is poor, the risk of overflow can be determined. Once the risk of overflow is detected, the speed of the inner drum can be adjusted accordingly to prevent overflow, ensuring the normal operation of the washing machine and user safety.

[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 features multiple different rinse settings, each corresponding to a specific set of rinse parameters. These parameters ensure an efficient and targeted rinse process. These rinse parameters primarily include a target speed, which is the speed the washing machine's inner drum must reach when the spray mechanism activates the spray. Additionally, in other conceivable implementations, the rinse parameters may also include a spray water flow rate, which is the amount of water sprayed onto the clothes per unit time during the spray rinse process.

[0090] The choice of rinse level is closely related to the properties of the clothing. An example of a clothing attribute is the dry weight of the clothing when dry, which helps the washing machine determine the total volume and total water absorption of the clothing during the spray rinse process. In other implementations, clothing attributes may also include the material of the clothing, as different materials have different water absorption properties. Before the clothing is spray rinsed, the rinse level to be executed needs to be determined based on the clothing's properties, and then the corresponding rinse parameters are determined based on the determined rinse level.

[0091] During the shower, water first flows through the clothes and then drains away due to centrifugal force. Different clothes have different water absorption rates depending on their weight. Therefore, when there are a lot of clothes, the water absorption rate is higher, which may cause the water discharge volume to be less than the water intake volume, thus causing overflow.

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

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

[0094] In some embodiments, reference Figure 3 The spray rinsing flow chart, which regulates the inner drum speed during the spray rinsing process according to the first motor parameter and the second motor parameter, 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 judgment threshold, reduce the inner drum speed; when the difference between the second motor parameter and the first motor parameter does not reach the overflow judgment threshold, maintain the inner drum speed until the set spraying time is reached.

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

[0098] If the difference between the second motor parameter and the first motor parameter reaches the set overflow threshold, it can be determined that the washing machine is at risk of overflowing. In this case, measures should be taken to reduce the inner drum speed to eliminate the risk of overflowing. Conversely, if the difference between the second motor parameter and the first motor parameter does not reach the overflow threshold, it can be considered that the washing machine is not at risk of overflowing. In this case, the inner drum speed can be maintained until the set spray 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 can 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 in this embodiment is a critical value used to determine whether a washing machine is at risk of overflow. The overflow determination threshold is set based on the specific performance of the washing machine and experimental data to ensure accurate determination of overflow risk during actual use. The overflow scheduling threshold can be a fixed value or vary depending on the rinse setting.

[0102] In one example, the rinsing parameters also include an overflow determination threshold value, and different rinsing gears correspond to different overflow determination threshold values, and the higher the dry clothes weight, the larger the overflow determination threshold value corresponding to the rinsing gear corresponding to the dry clothes weight interval. Specifically, different rinsing gears correspond to different overflow determination threshold values ​​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 value of this gear will also 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 includes the following steps:

[0104] S41. Before spray rinsing, obtain 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. Control the opening state of the sprinkler device according to the initial water level, the real-time water inlet flow rate and the real-time water level.

[0107] Specifically, since the washing machine has gone through the regular washing stage and the washing and dehydration stage before the spray device is turned on to spray and rinse the clothes, 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, the water flow rate of the spray device and the real-time water level of the outer drum are monitored in real time or periodically. This allows the initial water level, real-time water flow rate, and real-time water level to be used to further determine whether the washing machine is at risk of overflow. If the risk of overflow is determined, the spray status of the spray device can be promptly controlled, further effectively mitigating the risk of overflow, ensuring normal operation of the washing machine, and preventing potential losses and safety hazards caused by overflow.

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

[0110] S51. Determine an overflow calibration value based on 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 sprinkler 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 sprinkler device in a spraying state;

[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 into 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 washing machine's drainage volume. Since the F value is relatively fixed in most cases, the greater the drainage volume, the smaller the S1 value, which means that more water is discharged and the possibility of overflow is reduced. Conversely, if the drainage volume is small, the S1 value will increase, indicating 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 in FS is also a fixed value, and this difference serves as the overflow calibration value X. The washing machine's drainage volume F-S1 is then 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. The spraying state of the spray device is controlled accordingly. If F-S1>K*X, it indicates that the washing machine's drainage volume is large and there is no risk of overflow. The spraying state of the spray device is maintained until the set spraying time is reached. If F-S1≤K*X, it indicates that the washing machine's drainage volume is small and there is a risk of overflow. At this time, the spray device is controlled to stop spraying.

[0116] Furthermore, after the spraying device stops spraying, the difference between the real-time water inflow rate and the real-time water level must be re-determined. If the re-determined difference between the real-time water inflow rate and the real-time water level still satisfies: F-S1 ≤ K*X, the spraying device remains stopped. If the difference between the real-time water inflow rate and the real-time water level satisfies: F-S1 > K*X, the spraying device resumes spraying, thereby ensuring safe use of the washing machine.

[0117] The overflow coefficient is set based on the specific performance and experimental data of the washing machine to ensure that the risk of overflow can be accurately determined during actual use. The overflow coefficient can be a fixed value or vary depending on the rinse level. In one example, the rinse parameters also include the overflow coefficient, with different overflow coefficients corresponding to different rinse levels, and the overflow coefficients corresponding to the rinse levels with higher dry laundry weights are larger.

[0118] In general, this embodiment determines whether the washing machine is at risk of overflow by monitoring 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 overflow risk when the washing machine is at 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 overflow risk based on the drainage volume, and controls the spray device to stop spraying when the washing machine is at risk of overflow. This effectively avoids the occurrence of overflow when the inner drum speed is reduced to the minimum speed and still cannot eliminate the overflow risk. In addition, this embodiment also determines the rinsing gear according to the weight of the clothes 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 embodiments of the present application, the descriptions of the various embodiments have their own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments. The steps shown in the relevant flow charts can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flow charts, in some cases, the steps shown or described can be executed in an order different from that shown here. In other words, the order of steps described in the foregoing embodiments is only an example, and reasonable adjustment of the order of steps based on the content of the embodiments of the present application is also within the scope of protection of the embodiments of the present application.

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

[0121] like Figure 6As shown in the flowchart, the drive motor weighs the laundry before the wash cycle begins. Depending on the weight level, either the first or second spray level is used. The washing machine program categorizes laundry weight into L1, L2, L3, and L4 weight levels, with L1 corresponding to a very light load, L2 to a light load, L3 to a medium load, and L4 to a heavy load.

[0122] If the actual weight of the laundry corresponds to weight levels L1 or L2, the first spray level is used during the spray and rinse process, and the corresponding inner drum speed is V1. After entering the spray and rinse phase with a total spray duration of T, the inner drum is controlled to rotate before the spray device sprays and rinses the laundry. After the speed reaches V1 and stabilizes for t1, the spray device is controlled to spray the laundry.

[0123] If the actual weight of the laundry corresponds to weight levels L3 or L4, the second spray level is used during the spray and rinse process, and the corresponding inner drum speed is V2. After entering the spray and rinse phase with a total spray duration of T, the inner drum is controlled to rotate before the spray device sprays and rinses the laundry. After the speed reaches V2 and stabilizes for t1, the spray device is controlled to spray the laundry.

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

[0125] During the spray and rinse phase, motor power is collected in real time. Before the spray device sprays the clothes, a power value is collected every second for a period of time t1 after the inner drum speed stabilizes, 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 being executed, when W2-W1≥m1, it is judged that there is a risk of overflow and protective treatment is performed: after the speed V1 drops by 50rpm, it is maintained for t2 (t2 is 5s-10s). During t2, the power per second is collected and its average value W3 is taken. When W3-W1≥m1, V1 continues to drop by 50rpm and maintain t2. At the same time, the power per second is collected and the average value is taken. The above operation is repeated until W3-W1<m1. This speed is maintained until the total spraying time T is completed. Among them, m1 is 150W-250W.

[0127] If the second-speed spray is in progress, when W2-W1≥m2, it is determined that there is a risk of overflow and protective measures are taken: after the speed V2 drops by 50rpm, it is maintained for a period of 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. At the same time, the power per second is collected and the average value is taken. The above steps are repeated until W3-W1<m2. This speed is maintained until the spraying time T is completed. Among them, m2 is 250W-350W.

[0128] Further, such as Figure 7 As shown in the flowchart, while the spray device is on and spraying clothes, the real-time spray flow rate F is recorded, and the initial water level S in the outer drum before the spray is turned on is also recorded. This yields the overflow calibration value X = FS, where F is the real-time spray flow rate and S is the initial water level, both of which are fixed values. While the spray device is spraying and rinsing clothes, the real-time water level S1 in the outer drum is also recorded.

[0129] While the spray device is spraying and rinsing clothes, if F-S1 ≤ 0.3X during the first spray cycle, the washing machine determines that there is a risk of overflow. If F-S1 ≤ 0.6X during the second spray cycle, the system determines that there is a risk of overflow. In this case, the spray device is controlled to stop spraying while maintaining the inner drum speed. When F-S1 > 0.3X or F-S1 > 0.6X, the spray device is controlled to spray the clothes again.
