Currently, the general washing equipment eliminates foam residue through set fixed operations. For example, increasing the number of rinses or directly using a spraying method to defoam. However, since this method is a fixed operation, the system does not know whether the foam has been effectively eliminated after the operation is completed.

Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

The singular terms "a" and "the" may also include the plural form.

[0086] During the process of using various washing devices, users may encounter the situation of foam residue due to excessive detergent being added. Currently, washing devices generally eliminate foam residue through set fixed operations. For example, increasing the number of rinsing times or directly using the spraying method to defoam. However, since this method is a fixed operation, the system does not know whether the foam has been effectively eliminated after the operation is completed. Or, when the amount of foam residue is small, the fixed defoaming operation will extend the washing time and cause waste of resources.

[0087] For example, when using a washing machine, users may not be able to effectively rinse off the foam due to excessive laundry detergent being added, which affects the washing effect; it is also possible that the foam accumulated on the barrel wall, observation window, etc. after the clothes are washed and spun cannot be effectively removed, which affects the user experience.

[0088] Existing washing devices (such as washing machines) usually cannot detect foam after washing and dehydration. For clothes washing, a fixed number of rinsing operations are usually adopted, and for possible foam residue on the observation window or window gasket, a fixed-period spraying operation is usually adopted when the washing is completed. The existing solutions cannot determine whether the foam has been cleared, and at the same time, the spraying program and spraying period are fixed, which is not intelligent enough. The present application clears the foam by combining multiple control schemes through real-time monitoring of the foam position and residue amount.

[0089] Based on the above idea, the present application provides a control method for a washing device, as Figure 1 shown, the control method for the washing device in the embodiment of the present application includes the operations described in the following steps S101-S102:

[0090] Step S101, in a predetermined washing stage of the washing device, obtain foam residue information inside the washing space of the washing device;

[0091] In order to obtain foam residue information at different washing stages and different positions of the washing device, and thus more effectively eliminate foam, in this embodiment, foam residue information at three different positions is obtained in the following three washing stages, which are described in detail below:

[0092] In order to accurately and effectively obtain foam residue information on the object to be washed, the obtaining of the foam residue information inside the washing space of the washing device in the predetermined washing stage of the washing device in this embodiment includes: in a first predetermined washing stage of the washing device, obtain image information of the object to be washed inside the washing space; based on the image information of the object to be washed, obtain foam area information on the object to be washed, and use the foam area information on the object to be washed as the foam residue information.

[0093] In order to further accurately and effectively obtain the foam area information on the object to be washed, the obtaining of the foam area information on the object to be washed based on the image information of the object to be washed in this embodiment includes: perform feature extraction on the image information of the object to be washed to obtain the area of the object to be washed and the area of the foam on the object to be washed; calculate the ratio of the area of the foam on the object to be washed to the area of the object to be washed to obtain a first foam ratio, and use the first foam ratio as the foam area information on the object to be washed.

[0094] Specifically, taking the washing device as a washing machine as an example, the first predetermined washing stage may be after the washing machine finishes washing the clothes and before performing a dehydration operation on the clothes. In this washing stage, image information of the clothes in the inner tub of the washing machine is obtained through a camera. Among them, the camera is installed at a suitable position of the washing machine as long as it can capture a complete image in the inner tub. Then, the clothes and the foam on their surfaces in the inner tub are identified through the camera or the controller. Specifically, feature extraction algorithms such as histogram of oriented gradients or pre-trained neural networks can be used to perform feature extraction on the image information of the clothes to obtain the position and area of the foam on the clothes, as well as the area of the clothes. Calculate the ratio of the area of the foam on the clothes to the area of the clothes to obtain the foam ratio of the clothes, that is, the above-mentioned first foam ratio, and use this first foam ratio as the foam area information on the clothes, that is, as the foam residue information on the clothes.

[0095] In this embodiment, the area of the foam on the clothing obtained by the above feature extraction algorithm is obtained by accumulating multiple foam regions. The specific area value can be the absolute value of the area or the relative value of the area. When using the relative value to represent the area value, it is necessary to normalize the area of the foam on the above-mentioned clothing and the area of the clothing into a unified unit so that the finally obtained first foam ratio is consistent with that when using the absolute value of the area.

[0096] In this embodiment, the washing device includes an observation window, and the observation window is used for the user to observe the operation situation inside the washing space. In order to accurately and effectively obtain the foam residue information on the observation window of the washing device, in the predetermined washing stage of the washing device described in this embodiment, obtaining the foam residue information inside the washing space of the washing device includes: in the second predetermined washing stage of the washing device, obtaining the image information of the observation window; based on the image information of the observation window, obtaining the ratio of the area of the foam on the observation window to the area of the observation window as the second foam ratio, and using the second foam ratio as the foam residue information.

[0097] Specifically, still taking the washing device as a washing machine as an example, the second predetermined washing stage can be after the washing machine finishes dehydrating the clothing. In this washing stage, the image information of the observation window is obtained through a camera. The camera is installed at a suitable position of the washing machine as long as it can capture the complete image of the observation window. Then, the observation window and the foam on its surface are identified through the camera or the controller. Specifically, feature extraction algorithms such as histogram of oriented gradients or pre-trained neural networks can be used to extract features from the image information of the observation window to obtain the position and area of the foam on the observation window, as well as the area of the observation window, and calculate the ratio of the area of the foam on the observation window to the area of the observation window, and the foam ratio of the observation window can be obtained, that is, the above-mentioned second foam ratio, and this second foam ratio is used as the foam area information on the observation window, that is, as the foam residue information on the observation window.

[0098] Similarly, the area of the foam on the observation window obtained by the above feature extraction algorithm is obtained by accumulating multiple foam regions, as Figure 4 shown. The specific area value can be the absolute value of the area or the relative value of the area. When using the relative value to represent the area value, it is necessary to normalize the area of the foam on the above-mentioned observation window and the area of the observation window into a unified unit so that the finally obtained second foam ratio is consistent with that when using the absolute value of the area.

[0099] In this embodiment, the washing device includes a gasket, and the gasket is used to seal between the inlet housing of the washing device and the washing space. In order to accurately and effectively obtain the foam residue information on the gasket of the washing device, in the predetermined washing stage of the washing device in this embodiment, obtaining the foam residue information inside the washing space of the washing device includes: in the third predetermined washing stage of the washing device, obtaining the image information of the gasket; based on the image information of the gasket, obtaining the ratio of the area of the foam on the gasket to the area of the gasket as the third foam ratio, and using the third foam ratio as the foam residue information.

[0100] Specifically, still taking the washing device as a washing machine as an example, the gasket is the window gasket of the observation window, and the third predetermined washing stage can be after the defoaming operation on the observation window. In this washing stage, the image information of the gasket is obtained through a camera. The camera is installed at a suitable position on the washing machine as long as it can capture the complete image of the gasket. After that, the gasket and the foam on its surface are identified through the camera or the controller. Specifically, feature extraction algorithms such as histogram of oriented gradients or pre-trained neural networks can be used to extract features from the image information of the gasket, obtain the position and area of the foam on the gasket, and the area of the gasket, calculate the ratio of the area of the foam on the gasket to the area of the gasket, and the gasket foam ratio can be obtained, that is, the above-mentioned third foam ratio. Using this third foam ratio as the foam area information on the gasket, that is, as the foam residue information on the gasket.

[0101] Similarly, the area of the foam on the gasket obtained through the above feature extraction algorithm is obtained by accumulating multiple foam regions. The specific area value can be the absolute value of the area or the relative value of the area. When using the relative value to represent the area value, it is necessary to normalize the area of the foam on the gasket and the area of the gasket to a unified unit so that the finally obtained third foam ratio is consistent with that when using the absolute value of the area.

[0102] It should be noted that the camera for taking the image of the inside of the washing device barrel, the camera for taking the observation window, and the camera for taking the gasket can be the same camera or different cameras. When it is the same camera, a suitable installation position needs to be selected on the washing device to ensure that the camera can capture or capture the complete images of the inner barrel, the observation window, and the gasket after rotating the angle.

[0103] Of course, according to actual application requirements, it is also possible to set other washing stages of the washing device to obtain the foam residue information of other parts of the washing device in order to more effectively eliminate the foam residue on this part. This embodiment does not make specific restrictions on this.

[0104] Step S102: Based on the foam residue information, control the washing device to execute a predetermined defoaming program corresponding to the foam residue information to eliminate the foam remaining inside the washing space.

[0105] For the foam residue information at different positions obtained in the above three different washing stages, this embodiment designs corresponding specific defoaming programs, which are described in detail below:

[0106] To effectively eliminate the foam remaining on the object to be washed, the step of, based on the foam residue information, controlling the washing device to execute a predetermined defoaming program corresponding to the foam residue information to eliminate the foam remaining inside the washing space includes: determining whether the first foam ratio is greater than a first preset ratio threshold; when the first foam ratio is greater than the first preset ratio threshold, controlling the washing device to execute a predetermined defoaming program corresponding to the first foam ratio to eliminate the foam remaining on the object to be washed; wherein, executing the predetermined defoaming program corresponding to the first foam ratio includes at least one of the following items: increasing the predetermined number of rinsing times, increasing the predetermined number of dehydration times.

[0107] To further effectively eliminate the foam remaining on the object to be washed, the step of, when the first foam ratio is greater than the first preset ratio threshold, controlling the washing device to execute a predetermined defoaming program corresponding to the first foam ratio to eliminate the foam remaining on the object to be washed includes: when the first foam ratio is greater than the first preset ratio threshold, controlling the washing device to repeatedly execute the predetermined defoaming program corresponding to the first foam ratio until the first foam ratio is not greater than the first preset ratio threshold, or until the predetermined defoaming program corresponding to the first foam ratio reaches a preset number of executions.

[0108] Still taking the washing device as a washing machine as an example, that is, in this embodiment, a specific foam ratio threshold for clothes is set. When it is detected that the foam on the current clothes is greater than this threshold, it means that there is more foam remaining on the clothes and corresponding defoaming operations need to be performed.

[0109] Specifically, when it is detected that there is a large amount of foam on the laundry after the washing machine finishes washing and before the dehydration operation (i.e., when the first foam proportion is greater than the first preset proportion threshold), the washing machine will increase the number of rinsing operations by a predetermined number before the dehydration operation. For example, it will increase the rinsing operation by one or two times; alternatively, the washing machine can also increase the dehydration operation by one or two times to more effectively drain out the remaining foam and reduce the foam residue on the laundry. After performing the above operations, the system will detect the foam residue information on the laundry again. When it is still greater than the above first preset proportion threshold, the above rinsing operation and / or dehydration operation will be repeated until the first foam proportion is not greater than the first preset proportion threshold, or until the number of executions of the above rinsing operation and / or dehydration operation reaches the preset number of executions. After that, the washing machine starts to normally perform the subsequent dehydration operation.

[0110] In order to further effectively eliminate the remaining foam on the object to be washed, based on the foam residue information in this embodiment, controlling the washing device to execute a predetermined defoaming program corresponding to the foam residue information to eliminate the remaining foam inside the washing space includes: judging the preset proportion interval where the first foam proportion is located to obtain the current proportion interval; based on the current proportion interval, controlling the washing device to execute a predetermined defoaming program corresponding to the current proportion interval to eliminate the remaining foam on the object to be washed; where, executing the predetermined defoaming program corresponding to the current proportion interval includes at least one of the following items: increasing the predetermined number of rinsing times, increasing the predetermined number of dehydration times.

[0111] In order to more effectively eliminate the remaining foam on the object to be washed, based on the current proportion interval in this embodiment, controlling the washing device to execute a predetermined defoaming program corresponding to the current proportion interval to eliminate the remaining foam on the object to be washed includes: based on the current proportion interval, controlling the washing device to repeatedly execute the predetermined defoaming program corresponding to the current proportion interval until the first foam proportion is not greater than the minimum value of the preset proportion interval, or until the predetermined defoaming program corresponding to the current proportion interval reaches the preset number of executions.

[0112] Still taking the washing device as a washing machine as an example, that is, in this embodiment, multiple specific clothing foam proportion thresholds are set to form a preset proportion interval. When it is detected that the above first foam proportion is greater than the minimum value of this preset proportion interval, it indicates that there is a large amount of remaining foam on the laundry and corresponding defoaming operations need to be performed. At this time, judge again which proportion interval the first foam proportion is in, and adopt the defoaming program corresponding to this proportion interval to perform the defoaming operation.

[0113] Specifically, when it is detected that there is a large amount of foam on the laundry after the washing machine finishes washing and before the dehydration operation (i.e., when the first foam ratio is greater than the minimum value of the preset ratio range), the system will further determine the preset ratio range in which the first foam ratio is located to obtain the current ratio range. The washing machine will execute the defoaming program corresponding to this current ratio range before the dehydration operation. For example, it will increase the rinsing operation by one or two times to more effectively wash the residual foam on the laundry; or, it will increase the dehydration operation by one or two times to more effectively spin out the residual foam and reduce the foam residue on the laundry. After performing the above operations, the system will detect the foam residue information on the laundry again. When it is still greater than the minimum value of the above preset ratio range, it will determine the current ratio range again and execute the defoaming program corresponding to the current ratio range, such as the above rinsing operation and / or dehydration operation, until the first foam ratio is not greater than the minimum value of the preset ratio range, or until the preset defoaming program corresponding to the current ratio range reaches the preset execution times. After that, the washing machine starts to normally execute the subsequent dehydration operation.

[0114] To effectively eliminate the residual foam on the observation window of the washing device, based on the foam residue information described in this embodiment, controlling the washing device to execute a preset defoaming program corresponding to the foam residue information to eliminate the residual foam inside the washing space includes: determining whether the second foam ratio is greater than a second preset ratio threshold; when the second foam ratio is greater than the second preset ratio threshold, controlling the washing device to perform a blowing operation on the observation window until the second foam ratio is not greater than the second preset ratio threshold, or until the preset blowing time is reached.

[0115] Still taking the washing device as a washing machine as an example, that is, in this embodiment, a specific foam ratio threshold for the observation window is set. When it is detected that the foam on the current observation window is greater than this threshold, it means that there is a large amount of residual foam on the observation window and corresponding defoaming operations need to be performed.

[0116] Specifically, when the washing machine finishes the dehydration operation of the laundry and it is detected that there is a large amount of foam on the observation window (i.e., when the second foam ratio is greater than the second preset ratio threshold), the washing machine will perform a blowing operation on the observation window. In practical applications, hot air or cold air can be blown until the second foam ratio is not greater than the second preset ratio threshold, or until the preset blowing time is reached. After that, the washing machine stops running.

[0117] In order to effectively eliminate the residual foam on the gasket of the washing device, based on the foam residue information, the washing device is controlled to execute a predetermined defoaming program corresponding to the foam residue information to eliminate the residual foam inside the washing space, including: determining whether the third foam proportion is greater than a third preset proportion threshold; when the third foam proportion is greater than the third preset proportion threshold, controlling the washing device to perform a spraying operation on the gasket until the third foam proportion is not greater than the third preset proportion threshold, or until a preset spraying time is reached.

[0118] Still taking the washing device as a washing machine as an example, the gasket is the window gasket of the above-mentioned observation window. That is, in this embodiment, a specific gasket foam proportion threshold is set. When it is detected that the foam on the current gasket is greater than this threshold, it indicates that there is more residual foam on the gasket and corresponding defoaming operations need to be performed.

[0119] Specifically, after the washing machine completes the defoaming operation on the observation window and detects that there is more foam on the gasket (that is, when the third foam proportion is greater than the third preset proportion threshold), the washing machine will perform a spraying operation on the gasket. In practical applications, hot water or cold water can be sprayed until the third foam proportion is not greater than the third preset proportion threshold, or until the preset spraying time is reached. After that, the washing machine stops running.

[0120] In order to effectively remind the user and further improve the user experience, after controlling the washing device to execute a predetermined defoaming program corresponding to the foam residue information to eliminate the residual foam inside the washing space based on the foam residue information, the method in this embodiment further includes: detecting whether there is still residual foam inside the washing space; when there is still residual foam inside the washing space, sending a reminder message for reminding the user of the foam residue.

[0121] That is, in this embodiment, after repeatedly performing the above-mentioned defoaming operation and still being unable to effectively remove the foam residue, the user is reminded so that the user can timely know the situation of the foam residue or timely check whether the washing device has corresponding failures.

[0122] The following takes the actual application of applying the above control method to a washing machine as an example to further illustrate the washing device control method of the present application in detail:

[0123] In this embodiment, the foam detection on the clothes and the foam detection at the observation window / window gasket are two independent processes, which can exist simultaneously or only one of them exists.

[0124] Install a camera on the washing machine, which can take pictures inside the barrel to obtain its internal image information. Such as Figure 2As shown, before the dehydration operation is completed after the washing stage, the clothes and the foam on their surfaces inside the tub are identified by a camera. For the identification, feature extraction algorithms such as Histogram of Oriented Gradients or pre-trained neural networks can be used to detect the positions of the clothes and the foam, and the foam area is compared with the clothes area.

[0125] One or more thresholds are preset. For example, threshold 1 is 1 / 3, threshold 2 is 1 / 2, threshold 3 is 3 / 4, etc. If the foam proportion does not reach the minimum threshold, subsequent clothes treatment operations such as dehydration are carried out normally; if it reaches the minimum threshold, it is further judged which threshold interval it is in, and then the corresponding foam elimination operation is carried out. Among them, the foam elimination operation can be one or more treatment schemes according to one or more thresholds. For example, when reaching the above-mentioned threshold 1, an additional rinse is added; when reaching the above-mentioned threshold 2, 2 additional rinses are added; when reaching the above-mentioned threshold 3, an additional dehydration and an additional rinse are carried out, etc.

[0126] After the defoaming operation is completed, the foam proportion is detected again, and the previous process is repeated. At the same time, a maximum defoaming number is set. If it still cannot be eliminated after multiple rounds of operations, subsequent clothes treatment operations are carried out or the user is reminded.

[0127] The foam detection and control process on the observation window and the window gasket is as Figure 3 shown. The foam detection on the observation window and the window gasket can be only one of them or both coexist. The flowchart is described by taking the case where both coexist as an example.

[0128] As Figure 3 shown, after the washing machine finishes dehydrating the clothes, the observation window and the window gasket are foamed and identified. For the identification, feature extraction algorithms such as Histogram of Oriented Gradients or pre-trained neural networks can be used to obtain the foam position and its area in the image. Among them, there may be multiple foam regions, and the final foam area is the cumulative value of the areas of multiple foam regions. The schematic diagram of multiple foam regions is as Figure 4 shown.

[0129] The foam proportion threshold of the observation window (the foam on the observation window in the image accounts for the area of the observation window) is preset in advance. For example, the threshold is 1 / 3. After reaching this threshold, the foam on the observation window is eliminated, such as by blowing air (cold air or hot air). When the foam proportion drops below the threshold or reaches the maximum blowing time, the foam detection at the window gasket is carried out.

[0130] The foam proportion threshold of the window gasket (the foam on the window gasket in the image accounts for the area of the visible window gasket) is preset in advance. For example, the threshold is 1 / 5. After reaching this threshold, the foam on the window gasket is eliminated, such as by spraying (cold water or hot water). The spraying time depends on whether the foam proportion drops below the threshold or reaches the maximum spraying time.

[0131] Based on the above steps S101 - S102, the present application solves the technical problems in the prior art that the foam cannot be effectively eliminated and resources are wasted due to the adoption of a fixed defoaming method.

[0134] The present application observes the foam residue on the image recognition window / window pad and the clothes through image recognition, and performs operations such as blowing, spraying, drying, and rinsing according to the residue situation, which can effectively reduce the foam residue and effectively improve the intelligence level of the control scheme.
