The singular terms "one" and "the" may also include plural forms.

[0043] See attached Figure 1 , Figure 1 FIG. 1 is a flow chart of the main steps of a foam elimination method for a washing machine according to an embodiment of the present invention. Figure 1 As shown, the foam elimination method of the washing machine in the embodiment of the present invention mainly includes the following steps S11 to S14.

[0044] Step S11, in response to the washing program ending, acquiring an image inside the drum of the washing machine.

[0045] In this embodiment, a camera disposed in the washing machine may be used to take a picture of the inside of the drum to obtain an image of the inside of the drum of the washing machine.

[0046] Specifically, obtaining the image inside the drum of the washing machine includes obtaining the foam situation at the drum pad of the washing machine and / or obtaining the foam situation at the drum pad of the washing machine and the foam situation attached to the clothes.

[0047] Step S12, based on the drum image of the washing machine and the foam detection algorithm, it is determined whether the foam residue in the drum of the washing machine is higher than a first preset threshold.

[0048] Among them, the image inside the barrel of the washing machine and the foam detection algorithm are used to judge whether the foam residue in the current washing machine barrel is higher than a first preset threshold. Specifically, the judgment can be made by adopting a deep learning model suitable for image classification, such as a convolutional neural network. A pre-trained CNN model, such as ResNet, Inception, etc., can also be used, which can be fine-tuned and trained to judge the foam residue in the washing machine barrel.

[0049] In one embodiment, the first preset threshold value can be set by those skilled in the art according to actual needs. That is, when the foam residue in the washing machine drum is higher than the first preset threshold value, it is considered that the foam has not been rinsed clean at the end of the washing program and further defoaming operation is required; when it is lower than the first preset threshold value, it is considered that the foam has been rinsed clean at the end of the washing program and no further defoaming operation is required.

[0050] Step S13, selectively performing a defoaming operation based on the judgment result.

[0051] In one embodiment of the present invention, the washing machine is provided with a spray device, and the selectively performing the defoaming operation based on the judgment result includes:

[0052] If the judgment result is no, the defoaming operation is not performed;

[0053] If the judgment result is yes, a spray device is used to spray and defoam the inner barrel of the washing machine.

[0054] In one embodiment of the present invention, the step of spraying and defoaming the inner barrel of the washing machine using a spray device comprises:

[0055] Acquire a ratio of the foam area to the image based on the image in the drum of the washing machine;

[0056] Based on the ratio, water flow of different intensities is used for spraying.

[0057] Furthermore, in one embodiment, the method further comprises:

[0058] Acquiring a real-time image of the washing machine in the drum based on dynamic detection;

[0059] Acquire a ratio of the foam area to the real-time drum image of the washing machine based on the image, wherein the ratio is divided into a first ratio, a second ratio, or a third ratio;

[0060] Based on the ratio, a water flow of a corresponding first intensity, a second intensity, or a third intensity is adopted for spraying.

[0061] The larger the proportion of the foam area to the image, the greater the water flow intensity used during spraying, which can save water while cleaning the foam in the barrel and reduce the cost of removing foam.

[0062] In one embodiment of the present invention, the washing machine is further provided with a blowing device, and the performing of the defoaming operation further comprises:

[0063] determining whether the foam is within the spraying range of the spraying device based on the image inside the drum of the washing machine;

[0064] If the foam is within the spraying range of the spraying device, the spraying device is directly used to spray and defoam the inner barrel of the washing machine;

[0065] If foam exists and is outside the spraying range of the spraying device, a blowing device is used to transfer the foam outside the spraying range into the spraying range, and then the spraying device is used to spray and defoam the inner barrel of the washing machine.

[0066] The above-mentioned embodiment can transfer the foam outside the spraying range into the spraying range and remove it, so as to reduce the number of times the foam elimination operation is repeated and effectively eliminate the foam in the washing machine barrel.

[0067] Step S14: if a defoaming operation is performed, a rinsing operation is performed after the defoaming operation is completed.

[0068] Specifically, in one embodiment, the performing of the rinsing operation is performing one rinsing operation. In other embodiments of the present invention, those skilled in the art can set the number of rinsing times required for performing the rinsing operation as required.

[0069] In one embodiment of the present invention, the method further comprises:

[0070] After the rinsing operation is completed, returning to "re-acquiring the image inside the washing machine barrel", and judging whether the foam residue in the current washing machine barrel is higher than a first preset threshold based on the re-acquired image inside the washing machine barrel and the foam detection algorithm;

[0071] Until the judgment result is no, the defoaming operation is not performed.

[0072] Furthermore, the present invention provides an embodiment. Figure 2 , Figure 2 It is a detailed flowchart of a foam elimination method for a washing machine according to an embodiment of the present invention.

[0073] Step S21, in response to the washing program ending, acquiring an image inside the drum of the washing machine;

[0074] Step S22, based on the drum image of the washing machine and the foam detection algorithm, determine whether the foam residue in the drum of the current washing machine is higher than a first preset threshold; if the determination result is no, execute step S23, if the determination result is yes, execute step S24;

[0075] Step S23, not performing the defoaming operation;

[0076] Step S24, performing a defoaming operation; specifically, a spraying device may be used to spray and defoam the inner barrel of the washing machine;

[0077] Step S25, after the defoaming operation is completed, performing a rinsing operation;

[0078] After the rinsing operation in step S25 is completed, the process returns to step S21 to "re-acquire the image inside the drum of the washing machine", and based on the re-acquired image inside the drum of the washing machine and the foam detection algorithm, it is determined whether the foam residue in the current drum of the washing machine is higher than a first preset threshold value; until the judgment result is no, the defoaming operation is not performed.

[0079] The above embodiment can check the effect of foam elimination after the rinsing operation is completed, and further defoaming treatment can be performed on the possible situation where the foam elimination is not ideal, until the requirement of clean foam rinsing is met.

[0080] Furthermore, in one embodiment of the present invention, the washing machine is provided with a spray device, and the method further comprises:

[0081] When the rinsing program is running, images of the inside of the drum of the washing machine during the rinsing process are obtained at preset intervals;

[0082] Based on the image in the drum during the rinsing process and the foam detection algorithm, determining whether the foam residue in the current washing machine drum is higher than a second preset threshold;

[0083] If so, perform a spray defoaming operation to reduce the residual foam during the rinsing process.

[0084] Since the complete washing program includes a rinsing program, performing a defoaming operation during the rinsing program can effectively reduce the amount of foam attached to the clothes at the end of the washing program, which helps to reduce the working pressure of the defoaming operation after the washing program. In addition, performing a spray defoaming operation does not require pausing the rinsing program and will not affect the rinsing speed of the clothes.

[0085] In order to take into account the efficiency of the rinsing procedure, the second preset threshold is usually set higher than the first preset threshold.

[0086] Based on the above steps S11 to S14, the image inside the washing machine barrel and the foam detection algorithm are used to determine whether the foam residue in the washing machine barrel is higher than the first preset threshold, and a defoaming operation is selectively performed, thereby solving the problem that the foam is not completely eliminated after the washing program is completed.

[0087] Furthermore, by adopting technical solutions such as spraying with water flow of different intensities and combining with blowing equipment to eliminate foam, the efficiency of the defoaming operation is further improved. And by combining technical solutions such as re-detecting and performing the defoaming operation after the rinsing operation is completed, and performing the defoaming operation during the rinsing program, the level of foam elimination is further improved.

[0088] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effects of the present invention, different steps do not have to be performed in such an order. They can be performed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present invention.
