[0031] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0033] The technical solution provided by the embodiments of the present disclosure can be applied to a clothing processing device having a foam generating component, and the clothing processing device may be a washing machine, a dryer, a washer-dryer or other types of equipment having a foam generating component or capable of executing a foam cleaning program to achieve a foam cleaning function, which is not limited here.

[0034] In the technical solution provided by the embodiment of the present disclosure, the clothing processing equipment includes a foam generating component and a clothing processing chamber / load containing chamber; wherein, the foam generating component includes a mixing chamber (i.e., a containing chamber), a water inlet valve connected to the mixing chamber, a peristaltic pump and a foam delivery device (e.g., a foam pump); the water inlet valve is used to feed water or a dissolving medium such as an organic solvent into the mixing chamber, and water is used as an example for explanation hereinafter; the peristaltic pump is used to feed stock liquid (i.e., cleaning stock liquid) into the mixing chamber; the foam pump is connected to the clothing processing chamber, the clothing processing chamber can accommodate the load to be processed (e.g., clothing), the containing chamber can accommodate water and stock liquid, and transmit the cleaning medium to the foam delivery device, based on which, the foam delivery device is used to generate foam for cleaning the load to be processed, and then foam is delivered to the clothing processing chamber to achieve foam cleaning.

[0035] In response to the technical problems in the background technology, an embodiment of the present disclosure proposes a control method for a clothing processing device. By setting a second operation to be performed after the first operation is completed, the second operation of injecting cleaning medium into the accommodating cavity at least once can be used to clean the cleaning medium remaining in the first operation performed previously, thereby reducing the cleaning medium residue in the accommodating cavity and reducing the cleaning medium residue in the foam delivery device.

[0036] In some embodiments, the cleaning medium includes a dissolving medium and a cleaning stock solution. The dissolving medium can be, for example, a cleaning medium. Thus, by injecting the cleaning medium in batches and injecting the cleaning medium separately after the amount of the cleaning stock solution meets the demand, the containing chamber is flushed. Under the premise of ensuring that the target amount of cleaning medium and the target amount of cleaning stock solution match and meet the cleaning requirements, the cleaning medium residue in the containing chamber can be reduced, thereby improving safety.

[0037] In some embodiments, after the first operation and / or the second operation is completed, the cleaning medium and / or the washing medium in the foam delivery device cavity is discharged and specifically transported to the clothing processing cavity to clean the load therein, and it is helpful to accurately meet the dosage requirements of the cleaning solution and the washing medium, thereby improving the cleaning effect.

[0038] In some embodiments, the second operation may be performed at least once for each first operation to clean the receiving chamber at least once, which is beneficial for reducing residues in the receiving chamber.

[0039] The control method, control device and clothing processing device of the clothing processing device provided by the embodiments of the present disclosure are exemplarily described below in conjunction with the accompanying drawings.

[0040] For example, Figure 1 A flow chart of a control method provided by an embodiment of the present disclosure. Figure 1 , the control method may include the following steps:

[0041] S101, executing a foam delivery operation; the foam delivery operation includes a first operation of injecting a cleaning medium into the accommodating chamber at least once and a second operation of injecting a cleaning medium into the accommodating chamber at least once; wherein, after the first operation is completed, the second operation is executed.

[0042] The cleaning medium may include a dissolving medium and a cleaning stock solution, which is used to generate foam so as to clean the load in the clothing processing chamber. The cleaning medium is used to clean the receiving chamber. Since the solution obtained after cleaning also contains a certain amount of cleaning stock solution, it can also be used to generate foam and make up for the problem of missing actual amount due to residual cleaning stock solution, so that the amount of cleaning stock solution is more accurate and the cleaning effect is improved.

[0043] In some implementations, injecting the cleaning medium includes injecting a dissolving medium and a cleaning stock solution.

[0044] Illustratively, the dissolving medium may include water and an organic solvent, and the cleaning medium may include water and an organic solvent; the dissolving medium and the cleaning medium may be the same medium, or different media having both dissolving and cleaning functions, which is not limited here.

[0045] For example, in combination with the above, the injection of the dissolving medium and the injection of the cleaning stock solution can be achieved by using a water inlet valve and a peristaltic pump respectively, and the two can overlap, overlap or stagger in time, which is not limited here. In other embodiments, the dissolving medium and the cleaning stock solution can also be mixed in advance according to the target ratio and injected into the containing chamber together, which is not limited here.

[0046] In the embodiment of the present disclosure, the number of times the first operation of injecting the cleaning medium into the accommodating chamber is performed may be once, twice or more times, which can be set based on the capacity of the accommodating chamber, the amount of cleaning medium used, the concentration of the cleaning medium, and the requirements of the control method, and is not limited here; correspondingly, the number of times the second operation of injecting the cleaning medium into the accommodating chamber is performed may be once, twice or more times, which can be set based on the capacity of the accommodating chamber, the amount of cleaning medium used, the number of cleaning times required, and the requirements of the control method, and is not limited here.

[0047] In the embodiment of the present disclosure, by setting the first operation to end and executing the second operation, the second operation of injecting the cleaning medium into the containing chamber at least once can be used to clean the cleaning medium remaining in the first operation previously executed, thereby reducing the cleaning medium residue in the containing chamber, which is beneficial to reducing the safety risks caused by the cleaning medium residue.

[0048] In some implementations, performing the foam delivery operation further includes:

[0049] Determining that the first operation is finished, discharging the cleaning medium in the containing chamber by using the foam dispensing device;

[0050] and / or,

[0051] Determine that the second operation is finished, and use the foam delivery device to discharge the cleaning medium in the accommodating chamber.

[0052] In the disclosed embodiment, the first operation is completed, that is, the operation of injecting the cleaning medium into the accommodating chamber is completed. At this time, the cleaning medium can be discharged from the accommodating chamber by using the foam delivery device. For example, foam can be generated based on the cleaning medium and transported to the clothing processing chamber.

[0053] In the implementation of the present disclosure, the second operation is completed, that is, the operation of injecting the cleaning medium into the first receiving chamber is completed. At this time, the foam delivery device can be used to discharge the cleaning medium and the cleaning liquid contained therein out of the receiving chamber. For example, foam can be generated based on the cleaning medium containing the cleaning liquid and transported to the clothing processing chamber.

[0054] The foam delivery device may be started after the corresponding first operation and / or second operation is completed, or after the corresponding first operation and / or second operation starts for a reference time. Taking the second operation as an example, the reference time may be 1 / 2, 1 / 3 or other time values ​​or time ranges of the total time of a single injection of the cleaning medium; in some embodiments, the process of injecting the cleaning medium may also be a process of continuously injecting the cleaning medium and draining the water, and the number of times the cleaning medium is injected is divided by time, which is not limited here; by saving the interval between two injections of the cleaning medium, it is helpful to shorten the total time of the foam cleaning program, thereby saving the time for processing clothes.

[0055] In other embodiments, the cleaning medium and / or the washing medium in the accommodating chamber may also be discharged into other components that can accommodate the medium, which is not limited here.

[0056] In some implementations, the sum of the amount of cleaning medium and the amount of rinsing medium is the target amount for the load to be processed.

[0057] The target dosage for the load to be processed is the total dosage that can achieve the target cleaning effect for the load to be processed. For example, the target dosage can be characterized by parameters such as weight, volume, and duration, which are not limited here.

[0058] Exemplarily, the foam delivery operation may include N first operations and M second operations; wherein N is an integer greater than or equal to 1, M is an integer greater than or equal to 1, the total amount of the cleaning stock solution injected N times is equal to the target cleaning stock solution dosage, the total amount of the cleaning medium injected N+M times is equal to the target cleaning medium dosage, and the sum of the target cleaning stock solution dosage and the target cleaning medium dosage is the target dosage for the load to be processed. The target cleaning stock solution dosage is the total amount of stock solution required for the load to be processed, and the target cleaning medium dosage is the total amount of water required to match the target cleaning stock solution dosage.

[0059] For example, the value of N can be 1, 2, 3 or any other positive integer, which is not limited here. Similarly, the value of M can be 1, 2, 3 or any other positive integer, and the value of M can be the same as or different from the value of N, which is not limited here.

[0060] Before the second operation, the first operation may include the process of injecting a cleaning medium and a cleaning stock solution into the receiving chamber. The total amount of the cleaning stock solution injected N times can meet the target amount of the cleaning stock solution, corresponding to the normal liquid inlet and foaming process; in the operation of injecting only the cleaning medium into the receiving chamber M times, and no longer injecting the cleaning stock solution into the receiving chamber, the receiving chamber is cleaned with the injected cleaning medium, which reduces the residual cleaning medium on the one hand, and makes the total amount of the cleaning medium injected N+M times equal to the target amount of the cleaning medium on the other hand, thereby meeting the ratio requirement of the cleaning medium and the cleaning stock solution in the foam cleaning process.

[0061] In some implementations, the amount of cleaning medium used accounts for 50% to 90% of the target amount; the amount of washing medium used accounts for 10% to 50% of the target amount.

[0062] Specifically, in combination with the above, the amount of cleaning stock solution injected N times is the target cleaning stock solution amount; the amount of cleaning medium injected N times is at least half of the target cleaning medium amount, so as to fully mix with the stock solution and effectively foam; the amount of cleaning medium injected M times is the target cleaning medium amount minus the remaining amount after the cleaning medium amount injected in the first N times, so as to ensure that the target cleaning medium amount matches the target cleaning stock solution amount, and then inject the cleaning medium in stages, flush the residual mixed liquid with water, and reduce the residual mixed liquid.

[0063] In some implementations, before discharging the cleaning medium in the receiving chamber and / or discharging the cleaning medium in the receiving chamber, the method further includes:

[0064] Control the holding chamber to remain stationary for a preset time.

[0065] Such an arrangement can ensure that the cleaning medium in the accommodating chamber is fully mixed to facilitate foaming; and / or that the cleaning medium in the accommodating chamber fully blends and cleans the residual cleaning medium therein to reduce the residue.

[0066] Exemplarily, for cleaning media, the preset time length may be a first standing time length; for washing media, the preset time length may be a second standing time length.

[0067] In some embodiments, before the cleaning medium is injected into the laundry processing chamber each time, the cleaning medium and the cleaning stock solution may be pre-mixed and allowed to stand, so that the cleaning medium and the cleaning stock solution are fully mixed and the concentration of the mixture is uniform, thereby improving the cleaning effect. Exemplarily, the method may also include:

[0068] Get the first static time;

[0069] It is determined that the first static time period has ended, and a foam generation instruction is generated; the foam generation instruction is used to control the foam delivery device to deliver the cleaning medium to the clothing processing chamber.

[0070] The first resting time is used to limit the resting time of the cleaning medium and the cleaning stock solution. For example, the first resting time may be 30s, 20s, 40s or other time or time range, which is not limited here.

[0071] In the disclosed embodiment, after the cleaning medium and the cleaning stock solution enter the accommodating chamber and before the cleaning medium is injected, the mixed liquid of the cleaning medium and the cleaning stock solution can be left to stand in the accommodating chamber, and when the standing time reaches the first standing time, a foam generation instruction is generated to control the foam delivery device to generate foam based on the standing mixed liquid and inject the cleaning medium into the clothing processing chamber. Thus, the uniformity of the mixed liquid can be improved by standing, which is conducive to improving the cleaning effect.

[0072] In some embodiments, before each time the solution containing the cleaning medium and the residual cleaning medium in the receiving chamber is added into the laundry processing chamber, the cleaning medium and the residual cleaning medium may be dissolved and allowed to stand, so that more of the residual cleaning medium is dissolved in the cleaning medium, thereby facilitating the reduction of the residual cleaning medium in the receiving chamber. Exemplarily, the method may further include:

[0073] Get the second static time;

[0074] It is determined that the second static period has ended, and a discharge instruction is generated; the discharge instruction is used to control the foam delivery device to empty the solution containing the cleaning medium and the residual cleaning medium.

[0075] The second resting time is used to limit the resting time of the cleaning medium and the residual cleaning medium. For example, the second resting time may be 30s, 20s, 40s or other time or time range, which is not limited here.

[0076] In the disclosed embodiment, after the cleaning medium enters the accommodating chamber and before being put into the laundry processing chamber, the cleaning medium and the residual cleaning medium can be left to stand in the accommodating chamber, and the cleaning medium in which the residual cleaning medium has been dissolved can be emptied when the standing time reaches the second standing time. Thus, the degree of dissolution of the cleaning medium in the cleaning medium can be increased by standing, which is conducive to reducing the residual cleaning medium in the accommodating chamber.

[0077] In some implementations, for each first operation, the second operation is performed at least once.

[0078] Each time the first operation is performed, cleaning medium will remain in the containing chamber; each time the second operation is performed, that is, each time the cleaning medium is injected, the containing chamber can be flushed with the injected cleaning medium to reduce the residual amount of cleaning medium, and for the same first operation, the more times the second operation is performed, the less the residual amount.

[0079] In some implementations, after the first operation is completed, the method further includes:

[0080] The load receiving chamber of the clothes treating apparatus is controlled to rotate to perform a foam cleaning operation.

[0081] Among them, after the first injection of cleaning medium is completed, the clothing processing chamber can be controlled to rotate, and continue to rotate during the subsequent injection of cleaning medium, injection of cleaning liquid, standing, injection of cleaning medium, etc., so that the load to be processed continues to turn over in the clothing processing chamber, fully contacts and infiltrates the foam put into the clothing processing chamber, thereby improving the cleaning effect and saving the total program time.

[0082] Exemplarily, the laundry processing chamber may be controlled to continuously rotate in a first direction and a second direction according to a reference rotation-stop ratio to perform a foam cleaning operation; the first direction is opposite to the second direction.

[0083] Exemplarily, after the first injection of the cleaning medium is completed, the clothing processing chamber is controlled to continuously rotate so that the foam contacts, infiltrates and acts on the load, thereby achieving a foam cleaning operation.

[0084] During the rotation of the above-mentioned clothing processing chamber, the processes of injecting cleaning medium into the accommodating chamber, injecting cleaning liquid, standing, foaming, injecting cleaning medium, etc. can also be performed simultaneously to perform at least two non-conflicting operations at the same time, realize time multiplexing, and thus help save the total program duration.

[0085] Exemplarily, the reference start-stop ratio is the ratio between the duration of a single rotation and a single stop of the clothing processing chamber. For example, the start-stop ratio may be 10:3, and the corresponding rotation process of the clothing processing chamber may be: rotate in the first direction for 10 seconds, stop for 3 seconds, rotate in the second direction for 10 seconds, and stop for 3 seconds; in other embodiments, the reference start-stop ratio may also be other values, which are not limited here.

[0086] In the above embodiment, the first direction may be a clockwise direction, and rotation along the first direction may also be referred to as forward rotation; the second direction may be a counterclockwise direction, and rotation along the second direction may also be referred to as reverse rotation. For example, taking the clothes processing device as a dryer, the clothes processing chamber and the fan assembly may be driven by the same motor, and when the motor drives the clothes processing chamber to rotate along the first direction (e.g., clockwise), the motor drives the fan assembly to generate a large amount of air, and a large amount of air enters the clothes processing chamber; when the motor drives the clothes processing chamber to rotate along the second direction (e.g., counterclockwise), the fan assembly generates a small amount of air under the drive of the motor, so the airflow entering the clothes processing chamber is small.

[0087] In some embodiments, after the foam cleaning operation is completed, a drying operation may be performed to reduce the amount of residual water in the load. Exemplarily, the method may further include:

[0088] Confirm that the foam cleaning operation is completed and start the drying operation.

[0089] For example, for the drying operation, in order to speed up the loss of moisture in the load, the load needs to be tumbled as much as possible in the clothing processing chamber, and the air volume should be large. For this, the process of controlling the clothing processing equipment to rotate along the first direction in the clothing processing chamber is the main process of the drying operation. At this time, the air volume in the clothing processing chamber is large, which facilitates the hot air to take away the moisture in the load.

[0090] In the above embodiment, the cleaning medium may be water, the injection of the cleaning medium corresponds to the operation of the water inlet valve, the injection of the cleaning stock solution corresponds to the operation of the peristaltic pump, and the foam delivery device transports the cleaning medium or the cleaning medium including the cleaning medium to the clothing processing chamber, corresponding to the delivery of foam.

[0091] Based on this, Figure 2 A control method for a clothes processing device for removing residues in a mixing chamber provided by an embodiment of the present disclosure is shown, wherein two water inflows are taken as an example to exemplify the control method provided by the embodiment of the present disclosure.

[0092] refer to Figure 2 , the method may include the following steps:

[0093] S200, the program starts.

[0094] Exemplarily, the foam cleaning program starts. In some embodiments, for a dryer, the foam cleaning program can be built into the drying program, which is not limited here.

[0095] S201, first stage: the water inlet valve works for p minutes, the peristaltic pump works for q minutes, and the water and the stock solution all enter the mixing chamber and stand for 30 seconds for premixing; then the foam pump is turned on to generate foam and put it into the clothing processing chamber to start the foam cleaning operation.

[0096] Specifically, in the first stage, the water inlet valve works to let water into the mixing chamber, and the peristaltic pump works to let the stock liquid into the mixing chamber; after the water and the stock liquid all enter the mixing chamber, they are left to stand for 30 seconds to be fully mixed; then the foam pump works to generate foam and release it into the clothing processing chamber; during / after the foam release process, the clothing processing chamber is controlled to rotate to start the foam cleaning operation.

[0097] S202, second stage: the water inlet valve works for h minutes, the peristaltic pump does not work, and the water enters the mixing chamber and then stands for 30 seconds; then the foam pump is turned on to drain the water; during this period, the clothing processing chamber operates normally to maintain a continuous cleaning process.

[0098] Specifically, in the second stage, the water inlet valve works to feed water into the mixing chamber, and the peristaltic pump does not work, that is, no stock solution is fed into the mixing chamber; after all the water enters the mixing chamber, it is left to stand for 30 seconds to allow more of the residual mixed solution in the mixing chamber to dissolve in the water; then the foam pump works to generate foam and put it into the clothing treatment chamber. In the above process of the second stage, the clothing treatment chamber keeps running to maintain a continuous cleaning process.

[0099] S203, start drying, and keep the clothes processing chamber rotating forward.

[0100] Specifically, after the foam cleaning operation is completed, or in the latter stage, the drying operation is started. At this time, the clothing processing chamber maintains forward rotation (corresponding to the rotation in the first direction mentioned above). The wind volume is larger under this rotation direction, which is conducive to ensuring a better drying effect.

[0101] S204: The procedure ends.

[0102] In the disclosed embodiment, by optimizing the foam cleaning procedure and adopting the method of adding water in batches, the residual mixed liquid in the mixing chamber can be reduced, thereby reducing safety risks.

[0103] Specifically, the water intake process is divided into two stages. In the first stage, the peristaltic pump and the water intake valve are controlled to ensure that all the stock liquid and at least half of the water are input; after the foam pump sends all the liquid into the clothing processing chamber, the second stage of liquid intake is carried out, the peristaltic pump is controlled not to work, and the remaining water enters, and then is sent into the clothing processing chamber by the foam pump. In this way, it can be ensured that the total amount of water and the total amount of active substances (such as the total amount of stock liquid) meet the needs of foam cleaning. At the same time, because the water entering in the second stage has a flushing effect on the mixing chamber and the foam pump, the residue of the first stage of liquid intake can be flushed into the processing chamber, thereby reducing the residual mixed liquid in the mixing chamber.

[0104] In some embodiments, after foam is added to the clothing processing chamber for the first time, during subsequent operations, such as adding water, adding stock solution, standing for mixing, adding foam to the mixing chamber again, or adding an aqueous solution for flushing the residual mixture, etc., the clothing processing chamber continues to rotate according to a preset rotation and stop ratio, thereby maintaining a continuous cleaning process and ensuring a better cleaning effect.

[0105] In some embodiments, after water and stock solution are introduced into the mixing chamber, the two need to be left standing in the mixing chamber for a first standing time, so that the water and stock solution are fully mixed before subsequent foaming operations are performed, thereby improving the uniformity of the foam and improving the cleaning effect.

[0106] In some embodiments, after water is introduced into the mixing chamber again, the water needs to be left standing in the mixing chamber for a second standing time, so as to fully dissolve the residual mixed liquid in the mixing chamber, improve the flushing effect, reduce the residual concentration, and improve safety.

[0107] The following is an illustrative description of the technical effects that can be achieved by the embodiments of the present disclosure in combination with comparative experiments.

[0108] As shown in Table 1, this is a comparison table of residues corresponding to different examples.

[0109] Table 1 Comparison of residues corresponding to different examples

[0110] Example TDS value No.1: Tap water 260 No2: One-time liquid injection procedure 267 No. 3: The program provided in this embodiment 261

[0111] As shown in Table 1, the residual amount of the test solution under three different examples is given, and the residual amount is characterized by the total dissolved solids (TDS) value. Among them, Example No. 1 represents the use of tap water to enter and discharge the mixing chamber; Example No. 2 represents the use of a single liquid injection procedure in the related art, that is, a single water injection and liquid injection, and a bubbling and discharge procedure; Example No. 3 represents the procedure provided by the embodiment of the present disclosure, that is, a procedure including at least one water injection into the mixing chamber, illustratively, the water injection is divided into two times, and the water injection volume can be 300mL when the second water injection is made alone.

[0112] Among them, Example No. 1 is a blank control. By comparing Example No. 2 and Example No. 3, it can be seen that compared with Example No. 1, the TDS value of Example No. 2 is higher, that is, there will be a certain amount of mixed liquid residual in the mixing chamber after one liquid filling procedure, and a safety risk may occur if accumulated over a long period of time; and the TDS value of Example No. 3 is only 1 higher than the TDS value of Example No. 1, indicating that the two-water filling procedure provided by the embodiment of the present disclosure and the subsequent water filling to flush the mixing chamber can greatly reduce the TDS value, for example, it can be close to the value of tap water, indicating that the problem of the residual mixed liquid in the mixing chamber has been effectively improved, that is, the residual mixed liquid in the mixing chamber has been reduced, the safety risk has been reduced, and the safety has been improved.

[0113] Based on the same inventive concept, an embodiment of the present disclosure also provides a control device for a clothing processing device, which is used to execute the steps of any one of the control methods provided in the above embodiments to achieve corresponding beneficial effects.

[0114] For example, Figure 3 This is a schematic diagram of the structure of a control device provided by an embodiment of the present disclosure. Figure 3 The control device 300 may include: an operation execution module 301, used to execute the foam delivery operation; the foam delivery operation includes a first operation of injecting a cleaning medium into the accommodating chamber at least once and a second operation of injecting a cleaning medium into the accommodating chamber at least once; wherein, after the first operation is completed, the second operation is executed.

[0115] It is understandable that Figure 3 The control device shown is capable of executing the steps of any control method provided in the above-mentioned embodiments, and has corresponding beneficial effects.

[0116] The disclosed embodiment also provides a clothing processing device, including a processor and a memory.
