Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of cleaning devices, and specifically to a cleaning device and a rinsing method thereof, and a computer-readable storage medium. Background Art

[0002] Rinsing is an essential step in the washing process of a cleaning device. It is a process that separates the detergent from the load.

[0003] Taking a washing machine as an example, the current conventional rinsing method is: after the load is dehydrated, a large amount of clean water is added again, mixed thoroughly, and then drained and dehydrated, thereby reducing the concentration of detergent in the load, so that the residual detergent in the load is lower than the limit value. The lower the concentration of residual detergent in the load, the better the rinsing performance of this rinsing method.

[0004] refer to Figure 1 , water filling-rinsing is recorded as a complete rinsing process, and the existing conventional rinsing process usually takes the above-mentioned single rinsing process as a cycle, which is repeated multiple times to achieve the required rinsing performance. However, such a rinsing method cannot achieve the optimal total water consumption or the achievable rinsing performance. Summary of the invention

[0005] An object of an embodiment of the present invention is to provide an improved cleaning device and a rinsing method thereof.

[0006] Therefore, an embodiment of the present invention provides a rinsing method for a cleaning device, comprising: receiving a rinsing instruction; cyclically executing m rinsing processes, wherein water is drained before each rinsing process begins, and water is refilled at the beginning of each rinsing process, at least one of the m rinsing processes is executed in segments, and the water for this rinsing process is injected in batches during the segmented execution, and m is a positive integer.

[0007] The existing conventional rinsing process is to cycle a single rinsing process for multiple times, and inject the total water used for the rinsing process at the beginning of each rinsing process. This causes the load to always be rinsed in water with a high detergent concentration during the execution of a single rinsing process, affecting the rinsing performance. In comparison, this embodiment redistributes the water used for a single rinsing process in the conventional rinsing process, and uses the principle of multiple and small amounts to improve the rinsing performance without increasing the total water consumption. In other words, the purpose of reducing water consumption can also be achieved while ensuring the rinsing performance. Specifically, for at least one rinsing process in the m rinsing processes, the water injection action of the rinsing process is controlled to be executed in batches, which can essentially be understood as increasing the number of contacts between clean water and the load under the premise of the same total water consumption, and reducing the length of time the load is immersed in water mixed with high-concentration detergents.

[0008] Optionally, before each rinsing process begins, a dehydration step is also performed after drainage. Thus, by performing the dehydration step to reduce the water content of the load, it is helpful to reduce the detergent concentration in the load when the next rinsing process begins.

[0009] Optionally, the rinsing method further comprises: controlling the drum of the cleaning device to rotate to drain or dehydrate, wherein the rotation speed of the drum during drainage is lower than the rotation speed of the drum during dehydration. Thus, by controlling the drum to rotate at a suitable rotation speed, dehydration or drainage is promoted to assist in reducing the water content of the load.

[0010] Optionally, the segmented execution includes: executing n sub-processes cyclically in a single rinsing process, wherein the sub-processes include a rinsing step, wherein water is drained before each sub-process starts, and water is injected at the beginning of each sub-process, and n is a positive integer greater than or equal to 2. Thus, the single rinsing process is subdivided into multiple sub-processes, and the total water used in the single rinsing process is allocated to each sub-process for injection in batches, so as to reliably improve the rinsing performance under the premise of the same water consumption in a small amount and multiple times. The same water consumption may mean that the sum of the water injection amounts of each sub-process is the same as the total water consumption of the single rinsing process that is not executed in segments.

[0011] Optionally, the water injection amount of each sub-process in the n sub-processes is the same.

[0012] Optionally, the water injection amount of at least one sub-process is less than the water injection amount of the previous sub-process. Considering that the detergent concentration in the previous rinse is generally higher than the detergent concentration in the load in the next rinse when the water injection amount is constant, more water injection amount is allocated to the previous sub-process to improve the fusion effect with the detergent, thereby further improving the rinsing effect.

[0013] Optionally, the execution time of each of the n sub-processes is equal, or the execution time of at least one sub-process is different from the execution time of other sub-processes, such as the execution time of at least one sub-process is shorter than the execution time of the previous sub-process. Thus, by reasonably controlling the execution time of the sub-process, the rinsing effect is further improved.

[0014] Optionally, at the end of a single rinsing process performed in stages, the concentration of the detergent in the receiving chamber of the cleaning device is expressed based on the following formula:

[0015]

[0016] Among them, d n The concentration of the detergent in the receiving chamber at the end of a single rinsing process performed in stages; d 0 The concentration of the detergent in the holding chamber before the start of a single rinsing process performed in stages; r i-1 is the water content of the load in the holding chamber before the start of the i-th sub-process; wi is the water injection volume at the beginning of the i-th sub-process, 1≤i≤n. Therefore, each time a sub-process is executed, the detergent concentration decreases approximately in a quadratic order, which greatly improves the rinsing performance.

[0017] Optionally, in the m rinsing processes, the total water injection volume of the single rinsing process executed in segments is greater than or equal to the water injection volume of the single rinsing process executed in segments; and / or, in the m rinsing processes, the total execution time of the single rinsing process executed in segments is greater than or equal to the execution time of the single rinsing process executed in segments; and / or, in the m rinsing processes, the execution time of each sub-process in the single rinsing process executed in segments is less than the execution time of the single rinsing process executed in segments; and / or, in the m rinsing processes, the water injection volume of each sub-process in the single rinsing process executed in segments is less than the water injection volume of the single rinsing process executed in segments. Therefore, without increasing the total water consumption and / or total running time of the m rinsing processes, this embodiment sets the total water injection volume and / or total execution time of the single rinsing process executed in segments to be the same as the water injection volume and / or execution time of the single rinsing process executed in segments, and redistributes the water consumption and / or running time of the single rinsing process executed in segments, and improves the rinsing performance by using the principle of multiple small amounts; or, by appropriately allocating a little more water or running time to the rinsing process executed in segments, it is ensured that the water volume and running time injected in batches are sufficient to obtain a better rinsing effect. In addition, the execution time and / or water intake of the sub-process is less than the execution time and / or water intake of the single rinsing process executed in segments, and the rinsing effect is improved by rinsing in small amounts and multiple times.

[0018] Optionally, the segmented rinsing process includes at least the first or last rinsing process in the m rinsing processes. Thus, the segmented execution logic is used in the first rinsing process with the highest detergent concentration, or the segmented execution logic is used in the last rinsing process before the end of the rinsing process, so as to ensure that the entire rinsing process can obtain better rinsing performance.

[0019] Therefore, an embodiment of the present invention further provides a cleaning device, comprising: a box body, wherein a receiving chamber is provided in the box body for receiving a load; and a control module, which is used to execute the above rinsing method to perform the m rinsing processes for the load in the receiving chamber. Thus, by applying the above rinsing method, the rinsing performance of the cleaning device can be reliably improved.

[0020] Optionally, the cleaning device comprises a washing machine, and a drum is arranged in the box, and the drum is suitable for forming the accommodating cavity. Thus, the washing machine adopting the above rinsing method can obtain better rinsing performance when running a washing program.

[0021] Optionally, the cleaning device further comprises: a motor connected to the drum, the motor being used to drive the drum to operate, and the control module communicating with the motor to control the operation of the motor. Thus, the motor drives the drum to rotate to achieve dehydration, drainage and / or rinsing actions.

[0022] Optionally, the cleaning device further includes: a water pump connected to the drainage hole of the accommodating chamber, the control module is used to control the operation of the water pump to drain the water in the accommodating chamber; and / or a valve provided at the water injection hole of the accommodating chamber, the control module is used to control the opening or closing of the valve to inject water into the accommodating chamber or stop injecting water into the accommodating chamber. Thus, the drainage action is achieved by the water pump, and the water injection action is achieved by the valve.

[0023] Therefore, an embodiment of the present invention further provides a computer-readable storage medium, which is a non-volatile storage medium or a non-transient storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the steps of the above method are executed.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Figure 2 The present invention is a flowchart of a rinsing method for a cleaning device according to an embodiment of the present invention.

[0032] This embodiment can be applied to the washing scene of the cleaning device, and specifically can be applied to the rinsing process in the washing program. The cleaning device may include a washing machine, a washing and drying machine, a dishwasher and other electrical appliances with a rinsing function.

[0033] This embodiment can be executed by a control module of the cleaning device. The control module can be, for example, an existing component of the cleaning device and used to control the cleaning device to perform the washing function, or can be, for example, a newly added component dedicated to executing this embodiment.

[0034] Specifically, refer to Figure 2 The rinsing method of the cleaning device described in this embodiment may include the following steps:

[0035] Step S101, receiving a rinsing instruction;

[0036] Step S102, cyclically executing m rinsing processes, wherein water is drained before each rinsing process starts, and water is refilled at the beginning of each rinsing process, at least one of the m rinsing processes is executed in segments, and the water of this rinsing process is injected in batches during the segmented execution, and m is a positive integer.

[0037] More specifically, the rinse instruction can be used to trigger the rinse program, and the rinse program can include m rinse processes. The m rinse processes are executed cyclically, that is, after the previous rinse process is completed, the next rinse process is started until the number of executions of the rinse process reaches m times.

[0038] For example, in step S101, the rinsing instruction may be received from a user input instruction, which may be received from a human-machine interface of the cleaning device or from a smart device that communicates with the cleaning device. The smart device may be, for example, a mobile phone, an IPAD, or other smart home appliances in the same local area network as the cleaning device.

[0039] For another example, the rinsing procedure may be a step in the washing procedure being executed by the cleaning device. Accordingly, in step S101, in response to the completion of the previous step of the washing procedure, the control module may automatically trigger and generate a rinsing instruction.

[0040] Further, for each rinsing process, the total water consumption of the rinsing process may be predetermined. Similarly, the total water consumption of the entire rinsing procedure, that is, the sum of the total water consumption of each of the m rinsing processes, may be predetermined. In some embodiments, the correspondence between the rinsing process and the total water consumption may be predetermined and stored in a storage module of the cleaning device, and the control module may communicate with the storage module to obtain the required data.

[0041] For example, in step S102, the control module may predetermine the total amount of water used in each rinsing process, and control the injection of a corresponding amount of water when a corresponding number of rinsing processes are executed.

[0042] Furthermore, segmented execution can specifically refer to stage-by-stage or batch-by-batch execution. For example, the total water of the segmented rinsing process is injected in batches during the execution of the rinsing process, and the rinsing action is also performed in stages. The dividing point between the two stages of rinsing action can be, for example, the discharge of the original water, or the injection of new water.

[0043] Further, for a rinsing process that is executed in segments, the amount of water used for each batch of water injection during the segmented execution of the rinsing process may be predetermined. For example, the correspondence between the amount of water used for each stage of the segmented execution and the rinsing process may be pre-stored in the storage module. In step S102, the control module may call the correspondence to further determine the specific amount of water injected in each batch when determining that the i-th rinsing process needs to be executed in segments, 1≤i≤m.

[0044] From the above, this embodiment is adopted to redistribute the water used in a single rinsing process in a conventional rinsing process, and utilize the principle of multiple small amounts to improve the rinsing performance without increasing the total water consumption. In other words, the purpose of reducing water consumption can also be achieved while ensuring the rinsing performance. Specifically, for at least one rinsing process among the m rinsing processes, the water injection action of the rinsing process is controlled to be executed in batches, which can essentially be understood as increasing the number of contacts between clean water and the load under the premise of the same total water consumption, and reducing the length of time the load is immersed in the water mixed with a high concentration of detergent.

[0045] In some embodiments, it is possible to determine whether the rinsing program triggered by the rinsing instruction includes the segmented rinsing process described in the present embodiment based on parameters such as the washing program being specifically run and user input instructions.

[0046] For example, if the user inputs an instruction to select a regular rinsing process, then in response to receiving the rinsing instruction, the rinsing process triggered by the control module may be as follows: Figure 1 The conventional rinsing process shown in FIG. 1 is shown in FIG. 1 . At this time, the m rinsing processes cyclically executed in step S102 are not executed in sections.

[0047] For another example, if the washing program of this specific operation has a high requirement for rinsing performance, then in response to receiving the rinsing instruction, the rinsing process triggered by the control module may be as follows: Figure 2 and Figure 3 The segmented rinsing process shown. At this time, at least one of the m rinsing processes cyclically executed in step S102 is performed in segments.

[0048] Furthermore, the requirements of the washing program for rinsing performance can be determined according to the concentration of residual detergent in the load when the washing program is finished. For example, the lower the preset value that the residual detergent concentration in the load is required to be lower than, the higher the requirements of the corresponding washing program for rinsing performance.

[0049] In some embodiments, the rinsing procedures in different washing procedures may correspond to different total water consumption. Furthermore, the total water consumption for the non-segmented rinsing process and the total water consumption for the segmented rinsing process in different rinsing procedures may also be allocated differently. The storage module may store the correspondence between the washing procedure, the rinsing procedure and the total water consumption for the control module to call.

[0050] In one specific implementation, before each rinsing process begins, a dehydration step may be performed after draining.

[0051] Specifically, the water discharge step can be performed to discharge the water in the receiving chamber of the cleaning device, where the receiving chamber is used to receive the load, which may include objects to be washed, such as clothes, bed sheets, dishes, and the like.

[0052] Furthermore, performing the dehydration step can reduce the water content of the load. This is advantageous when the load is clothes, sheets, and other items to be washed that have certain water absorption properties. By performing the dehydration step to reduce the water content of the load, it helps to reduce the detergent concentration in the load when the next rinsing process begins.

[0053] In some embodiments, it can be determined according to the specific type of the cleaning device to which this embodiment is applied, whether a dehydration step needs to be performed after the water is drained at the end of the previous rinsing process and before the water is filled at the beginning of the next rinsing process. For example, when the cleaning device is a washing machine, the control module can add a dehydration step between the two rinsing processes when executing step S102. For another example, when the cleaning device is a dishwasher, in step S102, after the water is drained in the previous rinsing process, the control module can directly perform the water filling action of the next rinsing process.

[0054] In a specific implementation, the cleaning device may include a drum, and the drum is suitable for forming the accommodating cavity. Further, the dehydration action may be performed by controlling the drum to rotate at a certain speed to throw out the water in the load.

[0055] For example, the rinsing method of this embodiment may further include the step of controlling the drum of the cleaning device to rotate for dehydration. This step may be performed between two rinsing processes.

[0056] Further, when the water discharge step is performed, the drum can be in a stationary state. At this time, the water in the accommodating chamber can be discharged by an external water pump or gravity.

[0057] In a variation, the rinsing method of this embodiment may further include the step of controlling the drum of the cleaning device to rotate to drain water. That is, before each rinsing process begins, the drum is first controlled to rotate to drain water, and then water is added.

[0058] Further, the rotation speed of the drum during drainage may be lower than the rotation speed of the drum during dehydration.

[0059] Thus, dehydration or drainage is promoted by controlling the drum to rotate at a suitable speed to assist in reducing the water content of the load. Especially during drainage, the motor of the cleaning device is controlled to run at a low speed to drive the drum to rotate at a lower speed to assist in reducing the water content of the load.

[0060] In some embodiments, the dehydration step can also be achieved by increasing the temperature in the receiving chamber to dry and evaporate the moisture in the load.

[0061] In a specific implementation, the segmented execution may specifically include the steps of: cyclically executing n sub-processes in a single rinsing process, wherein the sub-processes include a rinsing step, wherein water is drained before each sub-process starts, and water is refilled at the beginning of each sub-process, and n is a positive integer greater than or equal to 2.

[0062] Specifically, there is no dehydration step between the rinsing steps of the two sub-processes. In other words, the last sub-process is drained at the end, and then the dehydration step is not performed, and the water injection action at the beginning of the next sub-process is directly performed.

[0063] Therefore, a single rinsing process is subdivided into multiple sub-processes, each of which uses a small amount of clean water and only drains water without dehydrating, so as to save energy and time. Furthermore, the total water used in a single rinsing process is allocated to each sub-process for injection in batches, so as to reliably improve the rinsing performance under the premise of the same water consumption in a small amount and multiple times. Among them, the same water consumption can mean that the sum of the water injection volume of each sub-process is the same as the total water consumption of a single rinsing process that is not executed in segments.

[0064] In a specific implementation, for the i-th rinsing process executed in segments, the water injection amount of each of the n sub-processes executed in segments can be the same. Taking m=3, i=1, n=3 as an example, the total water consumption of the first rinsing process is assumed to be 6L (liters), then the water injection amount of the three sub-processes can be 2L.

[0065] Under the premise of the same water consumption, if the first rinse process in the above example is not performed in segments, the total water consumption of 6L will be injected into the receiving chamber at the beginning of the rinse process. The injected water will only have one chance to contact the load in a single rinse process, and the expected rinsing effect may not be achieved. In contrast, in this example, 6L is divided into three 2L batches and injected into the receiving chamber in a single rinse process, which significantly increases the contact opportunities between clean water and the load and greatly improves the rinsing performance.

[0066] In a variation, for the i-th rinsing process that is executed in segments, among the n sub-processes that are executed in segments, the water injection amount of at least one sub-process may be smaller than the water injection amount of the previous sub-process.

[0067] Still taking m=3, i=1, n=3 as an example, the total water consumption of the first rinsing process is assumed to be 7L (liters), then the water injection volume of the first sub-process can be, for example, 3L, the water injection volume of the second sub-process can be, for example, 2L, and the water injection volume of the third sub-process can be, for example, 2L.

[0068] Considering that the water injection amount (for example, the total water consumption of a single rinsing process) is constant, the detergent concentration in the previous rinse is generally higher than the detergent concentration in the load in the next rinse. Therefore, this variation allocates more water injection amount to the previous sub-process to improve the fusion effect with the detergent, thereby further improving the rinsing effect.

[0069] In a variation, for the i-th rinsing process performed in segments, among the n sub-processes performed in segments, the water injection amount of at least one sub-process decreases as the number of cycles increases. That is, the water injection amount of each sub-process may decrease in sequence.

[0070] Still taking m=3, i=1, n=3 as an example, the total water consumption of the first rinsing process is assumed to be 6L (liters), then the water injection volume of the first sub-process can be, for example, 3L, the water injection volume of the second sub-process can be, for example, 2L, and the water injection volume of the third sub-process can be, for example, 1L.

[0071] In a specific implementation, in a single rinsing process executed in segments, the execution time of each of the n sub-processes can be equal, which is conducive to simplifying the control logic complexity of the control module, reducing costs and improving rinsing efficiency.

[0072] In a variation, for the i-th rinsing process executed in segments, among the n sub-processes executed in segments, the execution time of at least one sub-process may be different from the execution time of other sub-processes. Thus, the execution time of each sub-process may be appropriately controlled according to actual needs to further improve the rinsing effect.

[0073] For example, the execution time of the first subprocess is the longest, and the execution time of the remaining subprocesses can be the same.

[0074] For another example, the execution time of the n sub-processes may decrease as the number of executions increases. The decrease may be, for example, an arithmetic / geometric decrease, or may be, for example, a random decrease.

[0075] In a specific implementation, at the end of a single rinsing process performed in stages, the concentration of the detergent in the receiving chamber of the cleaning device (which can represent the concentration of the detergent in the load) can be expressed based on the following formula:

[0076]

[0077] Among them, d n The concentration of the detergent in the receiving chamber at the end of a single rinsing process performed in stages; d 0 The concentration of the detergent in the holding chamber before the start of a single rinsing process performed in stages; r i-1 is the water content of the load in the holding chamber before the start of the i-th sub-process; w i is the water injection amount at the beginning of the i-th subprocess, 1≤i≤n.

[0078] Specifically, still taking m=3, i=1, n=3 as an example, assuming that the detergent concentration d 0 , load water content r 0 (after dehydration), water injection volume w 1 At the end of the first sub-process, the concentration of the detergent in the holding chamber is:

[0079]

[0080] Assume that the load moisture content r at the end of the first subprocess 1 (After drainage), water injection volume w 2 At the end of the second sub-process, the concentration of the detergent in the holding chamber is:

[0081]

[0082] Assume that the load moisture content r at the end of the second subprocess 2 (After drainage), water injection volume w 3 At the end of the third sub-process, the concentration of the detergent in the holding chamber is:

[0083]

[0084] If the first rinsing process is not performed in sections, after the water is fully mixed in the containing chamber after one time, the concentration of the detergent in the containing chamber is:

[0085]

[0086] Therefore, each time a sub-process is executed, the detergent concentration decreases approximately quadratically, greatly improving the rinsing performance.

[0087] In this embodiment, the dosage unit of the detergent concentration may be, for example, gram / liter (g / L), and the dosage unit of the water content may be, for example, liter (L).

[0088] In a specific implementation, in the m rinsing processes, the total water injection amount of a single rinsing process performed in segments can be equal to the water injection amount of a single rinsing process performed without segments. That is, by adopting this embodiment, a better rinsing performance can be obtained while maintaining the total water consumption of the total rinsing process (i.e., the entire rinsing procedure) unchanged compared with the conventional rinsing process without segments.

[0089] In a variation, in the m rinsing processes, the total water injection amount of a single rinsing process performed in segments can be greater than the water injection amount of a single rinsing process not performed in segments. Therefore, a little more water is appropriately allocated to the single rinsing process performed in segments to ensure that the amount of water injected in batches is sufficient to obtain a better rinsing effect.

[0090] In a specific implementation, in the m rinsing processes, the total execution time of a single rinsing process executed in segments may be greater than or equal to the execution time of a single rinsing process not executed in segments.

[0091] Specifically, the total execution time of a single rinsing process executed in segments may include the sum of the execution times of each sub-process in the rinsing process. Further, the total execution time may also include the interval time between two sub-processes.

[0092] Furthermore, the execution time of a single rinsing process that is not executed in segments may include the time interval between two drainage actions before and after the start of the rinsing process. Furthermore, the execution time may also include the time for performing a dehydration action after the end of the rinsing process.

[0093] By ensuring that the total execution time of a single rinse process executed in segments is no less than the execution time of a single rinse process not executed in segments, it is beneficial to ensure that the detergent residue in the load and each batch of newly injected water are more fully integrated during the execution of each sub-process, so as to further improve the rinsing effect.

[0094] Therefore, without increasing the total water consumption and / or total running time of the m rinsing processes, this embodiment sets the total water injection volume and / or total running time of the single rinsing process executed in segments to be the same as the water injection volume and / or running time of the single rinsing process executed in segments, and redistributes the water consumption and / or running time of the single rinsing process executed in segments, thereby improving the rinsing performance by using the principle of multiple times and small amounts. Alternatively, by appropriately allocating a little more water or running time to the rinsing process executed in segments, it is ensured that the water volume and running time injected in batches are sufficient to obtain a better rinsing effect.

[0095] In a specific implementation, in the m rinsing processes, the execution time of each sub-process in the segmented single rinsing process may be shorter than the execution time of the non-segmented single rinsing process. Furthermore, the total execution time of the segmented single rinsing process may be equal to or slightly longer than the execution time of the non-segmented single rinsing process.

[0096] In a specific implementation, in the m rinsing processes, the water injection amount of each sub-process in a single rinsing process executed in segments may be smaller than the water injection amount of a single rinsing process not executed in segments.

[0097] Therefore, the execution time and / or water intake of the sub-process are shorter than the execution time and / or water intake of a single rinsing process that is not executed in segments, and the rinsing effect is improved by rinsing in small amounts and multiple times.

[0098] In a specific implementation, one or more rinsing processes that need to be performed in stages among the m rinsing processes may be predetermined.

[0099] For example, the segmented rinsing process may include at least: the first or last rinsing process among m rinsing processes.

[0100] In some embodiments, when the weight of the load contained in the accommodating cavity is relatively large, it can be determined that the first rinsing process among the m rinsing processes is performed in stages.

[0101] In some embodiments, when the weight of the load contained in the accommodating chamber is medium or small, it can be determined that the last rinse segment in the m rinse processes is executed.

[0102] Therefore, the segmented execution logic is adopted in the first rinsing process with the highest detergent concentration, or in the last rinsing process before the end of the rinsing program, to ensure that the entire rinsing program can achieve better rinsing performance.

[0103] Figure 3 1 is a schematic diagram of a cleaning device 1 according to an embodiment of the present invention. The cleaning device 1 in this embodiment may be, for example, a washing machine, a washing and drying machine, a dishwasher, and the like.

[0104] Specifically, refer to Figure 3 The cleaning device 1 of this embodiment may include: a housing 10, wherein a receiving chamber 101 is provided in the housing 10 for receiving a load. The load may be, for example, dishes, cloths, etc. to be cleaned.

[0105] More specifically, refer to Figure 3 The cleaning device 1 may further include a control module 13 for executing the above Figure 2 The rinsing method of the cleaning device in the illustrated embodiment is to perform the m rinsing processes for the load in the accommodating chamber 101 .

[0106] Therefore, by applying the above-mentioned rinsing method, the rinsing performance of the cleaning device 1 can be reliably improved.

[0107] Next, this embodiment will be specifically described by taking the cleaning device 1 as a washing machine as an example.

[0108] Specifically, in the application scenario where the cleaning device 1 is a washing machine, a drum 11 may be provided in the housing 10, and the drum 11 is suitable for forming a receiving chamber 101. In some embodiments, a water-containing outer barrel may also be provided in the housing 10, and the drum 11 can rotate in the outer barrel. The outer periphery of the drum 11 has through holes, and the water in the outer barrel can enter the drum 11 through the through holes so that the load in the drum 11 contacts the water and is immersed in the water for washing. At this time, the outer barrel and the drum 11 together form a receiving chamber 101. Therefore, when the washing machine using the above rinsing method runs a washing program, better rinsing performance can be obtained.

[0109] Furthermore, the cleaning device 1 may further include a motor 12 connected to the drum 11 and used to drive the drum 11 to operate, and the control module 13 communicates with the motor 12 to control the operation of the motor 12. For example, the output shaft of the motor 12 may be connected to the drum 11 to drive the drum 11 to rotate at a speed executed by the control module 13.

[0110] Thus, the drum 11 is driven to rotate by the motor 12 to achieve dehydration, drainage and / or rinsing actions.

[0111] In a specific implementation, the cleaning device 1 may further include a water pump 14 connected to the drainage hole 101a of the accommodating chamber 101, and the control module 13 is used to control the water pump 14 to run to drain the water in the accommodating chamber 101. Thus, the water pump 14 is used to achieve drainage.

[0112] Specifically, refer to Figure 3The drainage hole 101a is arranged at a lower position of the accommodating chamber 101 along the gravity direction. The drainage port 10a is arranged at the upper part of the box body 10, and accordingly, a water pump 14 can be arranged in the box body 10. When the control module 13 performs the drainage action, the water pump 14 is controlled to operate so as to pump the water in the accommodating chamber 101 from the drainage hole 101a to the drainage port 10a.

[0113] In a variation, the drain port 10a may be disposed below the housing 10. In this case, the water pump 14 may be eliminated, and the water in the housing 10 may naturally flow out of the drain hole 101a to the drain port 10a under the action of gravity.

[0114] In a specific implementation, continue to refer to Figure 3 The cleaning device 1 may further include a valve 15 disposed at the water injection hole 101b of the accommodating chamber 101, and the control module 13 is used to control the valve 15 to open or close to inject water into the accommodating chamber 101 or stop injecting water into the accommodating chamber 101. Thus, the water injection action is realized through the valve 15.

[0115] For example, when the control module 13 performs the water injection action, the control valve 15 is controlled to be opened. For another example, when the control module 13 performs the drainage, dehydration, and rinsing steps, the control valve 15 is controlled to be closed.

[0116] In a typical application scenario, refer to Figures 2 to 4 In response to detecting that the washing program is completed, the rinsing instruction is triggered. Assume that the control module 13 determines that the entire rinsing program needs to execute m=2 rinsing processes, wherein the first rinsing process needs to be executed in segments, and the number of segment executions n=3.

[0117] After the washing step and before starting the first rinsing process, the control module 13 controls the water pump 14 to drain water, and then controls the drum 11 to spin at a high speed to perform a dehydration action. After the dehydration is completed, the water pump 14 is controlled to stop working.

[0118] Then, the control module 13 controls the valve 15 to open, so as to inject water into the accommodation chamber 101 for the first time ( Figure 4 After the water injection is completed, the control module 13 controls the valve 15 to close and controls the drum 11 to rotate to perform the first sub-process (also called sub-rinsing).

[0119] After the first sub-process is executed, the control module 13 controls the water pump 14 to work to drain the water in the accommodating chamber 101. In some embodiments, during drainage, the control module 13 can further control the drum 11 to rotate at a low speed to assist drainage.

[0120] After the drainage is completed, the control module 13 determines the number of sub-process executions (hereinafter referred to as the number of sub-process executions) of the current round of segmented rinsing process. If the number of sub-process executions is less than 3 times, the aforementioned water injection, sub-process and drainage actions are repeated until the judgment result indicates that the number of sub-process executions reaches 3 times.

[0121] In response to the judgment result indicating that the number of sub-processes of the current round of segmented rinsing process has reached 3 times, the control module 13 determines that the current round of rinsing process has been completed. At this time, the control module 13 determines whether the number of executions of the rinsing process is 2 times or more. If it is not 2 times, the aforementioned drainage, dehydration and rinsing process actions are repeatedly executed until the judgment result indicates that the number of executions of the rinsing process reaches 2 times.

[0122] Furthermore, each time the rinsing process is started, it can be determined whether the rinsing process needs to be performed in stages. For example, in this application scenario, assuming that the second rinsing process does not need to be performed in stages, the control module can refer to Figure 1 The steps in the dashed box during the conventional rinsing process shown control the operation of the various components of the cleaning device 1 to complete a rinsing process that is not performed in stages.

[0123] In some embodiments, generally, the rinsing process is performed twice or more. For example, if each rinsing process has three sub-rinsing processes, the cleaning device 1 can perform a total of 6 rinsing processes. Moreover, the total water consumption of these 6 rinsing processes can be maintained the same as that of the conventional 2-round rinsing process, but the rinsing performance can be greatly improved.

[0124] The embodiment of the present invention further provides a computer-readable storage medium, which is a non-volatile storage medium or a non-transitory storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the steps of the rinsing method provided in any of the above embodiments are executed. Preferably, the storage medium may include a computer-readable storage medium such as a non-volatile memory or a non-transitory memory. The storage medium may include a ROM, a RAM, a magnetic disk or an optical disk, etc.
