[0050] 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.

[0051] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0052] According to an embodiment of the present application, an embodiment of a method for flushing a drying filter device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0053] like Figure 1 As shown, the drying filter device 3 flushing method is applied to a clothes processing device, the clothes processing device includes a first processing barrel 1 and a second processing barrel 2, the first processing barrel 1 and the second processing barrel 2 are arranged up and down, wherein the second processing barrel 2 is arranged below the first processing barrel 1, and the second processing barrel 2 is provided with a drying filter device 3, the drying filter device 3 is provided with a flushing device 4, and the flushing device 4 is provided with an external water supply path 41 and a reuse path for the washing water 42 of the first processing barrel; as shown Figure 2 As shown, the method includes the following steps:

[0054] S101 , in response to a dirty or blocked signal of the drying and filtering device 3 , obtaining an operating state of the first processing barrel 1 .

[0055] In one embodiment, when the drying filter device 3 needs to be cleaned, a dirty blockage signal is generated. Specifically, in one application scenario, a sensor or camera is installed in the clothing processing device to monitor the coverage of impurities or the amount of impurities on the drying filter device 3. When there are too many impurities, a dirty blockage signal is generated. In another application scenario, a timer is provided in the clothing processing device, and a dirty blockage signal is generated every time a preset time passes, so as to clean the drying filter device 3. It should be noted that the time for cleaning the drying filter device 3 can be set by oneself, and this embodiment does not specifically limit this.

[0056] In one embodiment, the drying filter device 3 refers to a device used to filter impurities in a clothing processing device, such as a filter or a filter assembly with a more complex structure. The drying filter device 3 in this embodiment refers to a device located in the clothing processing device that performs a filtering function. This embodiment does not limit the specific structure of the drying filter device 3. For ease of understanding, for example, the drying filter device 3 can be a drying filter device 3 shared by the first processing tub 1 and the second processing tub 2. The water after washing the clothes in the first processing tub 1 will pass through the drying filter device 3 to filter and reduce the impurities contained in the discharged water; the air when drying the clothes in the second processing tub 2 will pass through the drying filter device 3 to reduce the impurities contained in the air. For another example, the drying filter device 3 is a drying filter device 3 corresponding to the first processing tub 1 or the second processing tub 2, and is only used to filter the washing water in the first processing tub 1 or the drying air in the second processing tub 2.

[0057] In one embodiment, the operating state refers to the operating stage and / or operating parameters of the first treatment tub 1, and the operating stage and / or operating parameters reflect the state of the first treatment tub 1. The operating stage may be, for example, a washing stage or a drying stage, and may be more specific, for example, a washing stage including the first half of the wash, the middle half of the wash, and the last half of the wash. The operating parameters may be any one or more parameters during the operation of the first treatment tub 1, such as the motor speed of the first treatment tub 1, the water level in the first treatment tub 1, etc.

[0058] S102 : Determine a flushing strategy according to the operating state of the first processing barrel 1 .

[0059] In one embodiment, the flushing strategies are pre-set, that is, the number of flushing strategies and the content of each flushing strategy are fixed, and different operating states of the first processing barrel 1 correspond to different flushing strategies.

[0060] S103 , according to the flushing strategy, selectively utilize the washing water discharged from the first treatment tub 1 other than the first rinse and / or externally supplied water to flush the drying filter device 3 .

[0061] In one embodiment, different flushing strategies correspond to different water used. Some flushing strategies use the water in the first treatment barrel 1 to flush the drying filter device 3, some flushing strategies use flushing water to flush the drying filter device 3, and some flushing strategies use the water in the first treatment barrel 1 and flushing water to flush the drying filter device 3.

[0062] In one embodiment, the flushing water refers to water used exclusively in the laundry processing apparatus for flushing the drying filter 3. That is, if all the flushing water is used to flush the drying filter 3, water resources would be wasted. Therefore, when flushing the drying filter 3, water in the first treatment tub 1 in addition to the flushing water is used, thereby conserving water resources.

[0063] Through the above steps, when it is necessary to flush the drying filter device 3, the operating status of the first treatment barrel 1 is determined, and a flushing strategy is selected based on the operating status of the first treatment barrel 1. When flushing the drying filter device 3 according to the flushing strategy, the water in the first treatment barrel 1 can be used instead of just the flushing water. This allows the flushing process of the drying filter device 3 to reuse the wastewater in the first treatment barrel 1, thereby reducing the amount of flushing water used and conserving water resources.

[0064] In another embodiment of the present application, the operating state of the first processing barrel 1 includes an operating stage of the first processing barrel 1 .

[0065] The step of determining a flushing strategy according to the operating state of the first processing barrel 1 includes:

[0066] When the operation stage of the first processing barrel 1 is the preset target stage, a first strategy of flushing the drying and filtering device 3 with the washing water in the first processing barrel 1 is determined.

[0067] In one embodiment, the operating state includes an operating stage. The operating stage refers to the operating mode of the first processing tub 1, such as a drying mode corresponding to a drying stage, a washing mode corresponding to a washing stage, and a sterilization mode corresponding to a sterilization stage. This embodiment does not specifically limit the operating stages of the laundry processing apparatus.

[0068] In one embodiment, a target stage is set in advance. Since the flushing of the drying filter device 3 has certain requirements, such as the amount of water or the amount of impurities in the water, when the first treatment barrel 1 is in the target stage, the water in the first treatment barrel 1 can meet the requirements for flushing the drying filter device 3. Therefore, the water when the first treatment barrel 1 is in the target stage can be used to flush the drying filter device 3.

[0069] For ease of understanding, for example, when there is a water volume requirement for rinsing the drying filter device 3, the target phase can be set to the washing phase. This facilitates using the large amount of washing water corresponding to the washing phase to rinse the drying filter device 3, thereby meeting the water volume requirement for rinsing the drying filter device 3. Conversely, if the first treatment tub 1 is in the rinsing phase, the amount of water in the first treatment tub 1 may be less, thus failing to meet the water volume requirement and, consequently, failing to use the water in the first treatment tub 1 to rinse the drying filter device 3.

[0070] Through the above steps, different operating stages of the first processing barrel 1 are used to determine whether the water in the first processing barrel 1 can be used to flush the drying filter device 3, which helps to meet the requirements for flushing the drying filter device 3, thereby ensuring the cleaning effect of the drying filter device 3.

[0071] In another embodiment of the present application, when the operation stage of the first processing barrel 1 is a preset target stage, determining a first strategy for flushing the drying filter device 3 with water in the first processing barrel 1 includes:

[0072] When the operation phase of the first processing barrel 1 is the rinsing phase and it is not the first rinsing phase, a first strategy of flushing the drying and filtering device 3 with the water in the first processing barrel 1 is determined.

[0073] Specifically, in one embodiment, the target stage is the rinsing of the first treatment tub 1, and it is not the initial rinsing stage. On the one hand, the rinsing stage has a certain amount of water, which is convenient for meeting the water volume requirement for rinsing the drying filter device 3. On the other hand, the fact that it is not the initial rinsing stage indicates that the drying filter device 3 has already been rinsed once or several times, and the rinsing water is less likely to carry impurities. Moreover, the turbidity of the rinsing water is lower than that of the washing water, which facilitates improving the rinsing effect of the drying filter device 3.

[0074] In another embodiment of the present application, the operating state of the first processing barrel 1 includes operating parameters, and the operating parameters include drainage time parameters.

[0075] The step of determining a flushing strategy according to the operating state of the first processing barrel 1 includes:

[0076] When the drainage time parameter satisfies the waiting time, a first strategy of flushing the drying and filtering device 3 with the water in the first processing barrel 1 is determined.

[0077] In one embodiment, the operating parameters include a drainage time parameter, wherein the drainage time parameter refers to the time from the start of drainage of the first treatment barrel 1. The waiting time is a preset value, such as 1 hour or 30 minutes, and this embodiment does not limit the specific value of the waiting time.

[0078] When the drainage time parameter satisfies the waiting time, it proves that the first processing barrel 1 will be drained after a time shorter than the waiting time, so that the drying and filtering device 3 can be flushed with the water in the first processing barrel 1 .

[0079] In one embodiment, if the drainage time parameter does not meet the waiting time, a second strategy is determined, wherein the second strategy is to flush the drying filter device 3 with flushing water.

[0080] Through the above steps, when the time when the drying filter device 3 needs to be flushed is close to the time when the first processing barrel 1 is drained, that is, after the first processing barrel 1 is drained, the drying filter device 3 is flushed with the water in the first processing barrel 1, which helps to save water resources.

[0081] In another embodiment of the present application, the operating parameters of the first treatment barrel 1 also include a remaining drainage volume parameter.

[0082] Before flushing the drying filter device 3 with the washing water in the first treatment barrel 1 according to the first strategy, the method further includes:

[0083] Determining whether the remaining drainage volume parameter of the first treatment barrel 1 meets the water consumption threshold;

[0084] If not, according to the second strategy, the washing water in the first treatment barrel 1 and the external water supply are used to rinse the drying and filtering device 3 .

[0085] In one embodiment, the remaining drainage parameter refers to the maximum amount of water that can be drained from the first treatment barrel 1. Alternatively, if all the water in the first treatment barrel 1 needs to be drained, the remaining drainage parameter refers to the amount of water remaining in the first treatment barrel 1. When the remaining drainage parameter meets the water volume threshold, it proves that the amount of water that needs to be drained from the first treatment barrel 1 can meet the rinsing water volume requirement of the drying filter device 3. In this case, the second strategy is used to rinse the drying filter device 3, which helps conserve water resources. If the remaining drainage does not meet the water volume threshold, it proves that the amount of water that needs to be drained from the first treatment barrel 1 is insufficient to rinse the drying filter device 3. In this case, the second strategy is used, utilizing the water in the first treatment barrel 1 as well as the rinsing water.

[0086] It should be noted that when the second strategy is used to rinse the drying filter device 3, the water in the first treatment barrel 1 and the rinsing water may be discharged simultaneously, or the water in the first treatment barrel 1 may be discharged first and then the rinsing water may be discharged to rinse the drying filter device 3. This embodiment does not specifically limit this.

[0087] Through the above steps, on the one hand, considering the remaining drainage parameter in the first treatment tank 1 helps to ensure that there is sufficient water to flush the filter chamber, thereby improving the flushing effect of the drying filter device 3. On the other hand, even if the remaining drainage parameter does not meet the water volume threshold, the water in the first treatment tank 1 is still used, which helps save water resources.

[0088] In another embodiment of the present application, the operating state of the first treatment barrel 1 includes water turbidity;

[0089] The step of determining a flushing strategy according to the operating state of the first processing barrel 1 includes:

[0090] When the turbidity of the washing water in the first treatment tub 1 is less than a preset turbidity threshold, a first strategy of flushing the drying filter device 3 with the water in the first treatment tub 1 is determined.

[0091] In one embodiment, the operating state further includes water turbidity, and the flushing strategy is determined based on the water turbidity and a preset turbidity threshold. When the water turbidity is less than the turbidity threshold, the drying filter device 3 is flushed with water in the first treatment barrel 1.

[0092] Through the above steps, the flushing strategy is determined according to the turbidity of the water in the first treatment barrel 1. No matter which operating stage the first treatment barrel 1 is in, the turbidity threshold is easily met, which is beneficial to increase the probability of the water in the first treatment barrel 1 being reused and save water resources.

[0093] In another embodiment of the present application, the drying and filtering device 3 is used to filter impurities in the second processing barrel 2 .

[0094] The embodiment of the present application further provides a method for flushing a drying filter device 3, which is applied to a multi-barrel washing machine. The multi-barrel washing machine includes a first processing tub 1 and a second processing tub 2, which are arranged one above the other, wherein the second processing tub 2 is arranged below the first processing tub 1, and the second processing tub 2 is provided with a drying filter device 3, the drying filter device 3 is provided with a flushing device 4, and the flushing device 4 is provided with an external water supply path 41 and a path for reusing washing water from the first processing tub 1; the method further includes:

[0095] S801, obtaining a dirty or blocked signal of the drying filter device 3 of the second processing barrel 2 in the drying process.

[0096] S802: Detect whether the first processing bucket 1 is running.

[0097] If the first processing tub 1 is running, then detecting whether the first processing tub 1 is in a washing state;

[0098] If the first processing tub 1 is in a washing state, the current washing stage of the first processing tub 1 is detected;

[0099] If the first processing tub 1 is currently in the rinsing stage of the preset sequence, the second processing tub 2 is instructed to rinse the drying filter device 3 with the washing water in the rinsing stage of the preset sequence.

[0100] In one embodiment, the preset order rinsing stage refers to the preset nth rinsing stage, where n is a positive integer greater than 1; in another embodiment, the order refers to the second time, that is, the preset second rinsing stage, indicating that the clothing processing device rinses the clothes for the second time.

[0101] In another embodiment of the present application, the instructing the second processing barrel 2 to rinse the drying filter device 3 using the washing water in or after the preset sequence rinsing stage of the first processing barrel 1 includes:

[0102] Calculate or obtain the time T2 from the current rinsing water in the first treatment tub 1 to its drainage process;

[0103] The second processing barrel 2 is set to dry the filter device 3 and rinse waiting time T1 according to the time T2, T1 ≥ T2, and the second processing barrel 2 is kept in a drying state during the time T1.

[0104] In another embodiment of the present application, the instructing the second processing barrel 2 to rinse the drying filter device 3 using the washing water in or after the preset sequence rinsing stage of the first processing barrel 1 includes:

[0105] Calculate or obtain the time T2 from the current rinsing water in the first treatment tub 1 to its drainage process;

[0106] Calculate or obtain the flushing time T3 of the second processing barrel 2 according to the degree of dirt and blockage of the drying and filtering device 3 of the second processing barrel 2;

[0107] Calculate the total duration T of T2 and T3;

[0108] The calculated result of the total time T is sent to the user to confirm whether to use the washing water of the first treatment barrel 1 to rinse the drying filter device 3 of the second treatment barrel 2;

[0109] If the user confirms yes, the user is prompted to determine whether to automatically start washing the drying filter device 3 of the second processing barrel 2 after reaching the time T2 or to set the user to wait for the second processing barrel 2 to dry the filter device 3 and rinse it.

[0110] In one embodiment, T3 can be calculated using a pre-set relationship table. For example, if a sensor or camera determines that the congestion level is medium, the time value corresponding to medium is retrieved from the relationship table as T3. This embodiment does not limit the process for calculating T3; it is intended that different T3 values ​​be obtained for different congestion levels, and that the more severe the congestion, the greater the T3 value.

[0111] In one embodiment, the user can select the flushing node of the drying filter device 3 by himself.

[0112] Through the above content, the operating state and operating stage of the first processing barrel 1 are gradually judged, which helps to ensure that the water in the first processing barrel 1 is beneficial for flushing the drying filter device 3 and ensure the flushing effect.

[0113] For ease of understanding, in one embodiment, the first processing barrel 1 is an upper barrel, and the second processing barrel 2 is a lower barrel, wherein the upper barrel is located above the lower barrel. Figure 3 As shown in the figure, when dirt and blockage appear during the drying process of the lower drum, it proves that the filter needs to be flushed.

[0114] At this point, first determine whether the upper bucket is running;

[0115] If the upper tub is running, determine whether the upper tub is in the rinsing stage;

[0116] If the upper bucket is not running, directly open the filter flushing valve and use flushing water to flush the filter.

[0117] If the upper barrel is in the rinsing stage, determine whether the upper barrel is in a non-first rinsing stage;

[0118] If the upper bucket is not in the rinsing stage, directly open the filter flushing valve and use flushing water to rinse the filter.

[0119] If the upper tub is not in the first rinsing stage, it is determined whether the time T from the upper tub to the drain program (ie, the drain time parameter) is less than T1 (ie, the waiting time).

[0120] If the upper barrel is not in the first rinsing stage, directly open the filter flushing valve and use flushing water to flush the filter.

[0121] If T is less than T1, the lower drum drying keeps running and waits.

[0122] If T is greater than or equal to T1, directly open the filter flushing valve and use flushing water to flush the filter.

[0123] During the waiting process, determine whether the upper barrel has reached the drainage procedure.

[0124] If the upper bucket reaches the draining process, the upper bucket drain valve P1 opens and flushes the filter.

[0125] If the upper bucket has not reached the draining process, continue waiting.

[0126] During the filter flushing process, determine whether the rinsing water in the upper bucket is empty.

[0127] If it is empty, the drain valve of the upper barrel P1 is closed, and then the drying and filtering device 3 is rinsed.

[0128] If it is not empty, keep the upper drum drain valve P1 open and rinse the filter.

[0129] In another embodiment, if Figure 4 As shown, Figure 3 The difference is that after determining whether the upper tub rinse water is empty, if it is empty, the upper tub drain valve P1 is closed, the filter flushing valve is opened, and the filter is flushed with flushing water;

[0130] If it is not emptied, close the upper tub drain valve P1 and open the drain valve P2 to drain the remaining rinsing water out of the tub.

[0131] The embodiment of the present application further provides a controller for flushing the drying filter device 3 in the clothing processing device using the above-mentioned method for flushing the drying filter device 3.
