[0037] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0038] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0039] The foam detection method, apparatus, clothing treatment equipment, and medium provided in the embodiments of this disclosure are described below with reference to the accompanying drawings.

[0040] Figure 1 This is a flowchart illustrating a foam detection method provided in an embodiment of this disclosure. This method is applicable to applications requiring advance detection of foam levels in garment processing equipment. This method can be executed by the foam detection device provided in this embodiment, which can be implemented using software and / or hardware. Figure 1 As shown, the method includes the following steps:

[0041] S101. Obtain the conductivity of the washing liquid in the drum when the garment processing equipment is in the first water intake stage.

[0042] Specifically, the garment processing equipment may include a sensor, such as a conductivity sensor. The sensor can be installed at the bottom of the outer drum of the garment processing equipment to ensure that it is always in contact with the washing water (washing liquid) during the washing process, thereby detecting the conductivity of the washing water. For example, the garment processing equipment may be a washing machine.

[0043] Specifically, the conductivity of the washing water during the washing process can be detected in real time by the garment processing equipment. This means the conductivity of the washing water can be continuously acquired, or it can be detected at set intervals. This allows the equipment to obtain the conductivity of the washing water during the washing process while effectively reducing the power consumption of conductivity detection. The washing process may include an initial water intake process and a water replenishment process; alternatively, it may include an initial water intake process and multiple water replenishment processes, with the water replenishment process occurring after the initial water intake process.

[0044] It should be noted that the present disclosure does not specifically limit the time limit for setting the interval described in the foregoing embodiments, and it can be set based on the specific detection requirements of conductivity. In addition, in other embodiments, other technical means well known to those skilled in the art can also be used to obtain the conductivity of the washing water during the washing process of the clothing processing equipment, and the present disclosure does not specifically limit this.

[0045] In some embodiments, the advance detection method includes: during the first water intake process, using a sensor to detect and obtain the conductivity of the washing water, and determining whether the amount of foam inside the garment processing device is excessive based on the detected conductivity; when the conductivity of the washing water exceeds a first preset conductivity during the first water intake, further obtaining the conductivity of the washing water during the replenishment process of the garment processing device; and detecting whether the amount of foam inside the garment processing device drum is excessive based on the conductivity corresponding to the replenishment process.

[0046] S102. Based on the fact that the conductivity corresponding to the first water intake stage is greater than the first preset conductivity, obtain the conductivity of the washing liquid in the drum when the clothing processing equipment is in the water replenishment stage.

[0047] Specifically, the conductivity of the washing water is related to the detergent concentration. For example, the higher the detergent concentration, the greater the conductivity; conversely, the lower the detergent concentration, the lower the conductivity. Higher detergent concentrations result in more foam being generated inside the garment processing equipment, while lower concentrations result in less foam. Based on this logic, the conductivity of the washing water is positively correlated with the amount of foam generated inside the garment processing equipment; that is, the higher the conductivity, the more foam is generated, and vice versa. For example, the garment processing equipment's memory can pre-store a table corresponding to the conductivity and the amount of foam generated inside. After obtaining the conductivity during the washing process, the amount of foam inside the equipment can be determined by looking up the table. Therefore, the amount of foam generated inside the washing machine drum can be detected by obtaining the conductivity of the washing water, thus determining whether the amount of foam generated inside the garment processing equipment is excessive.

[0048] Specifically, when the garment processing equipment first enters the water intake process, detergent enters the drum along with the water. Because the detergent concentration is very high at this time, the conductivity value detected by the sensor is relatively large, typically reaching the full scale A0. For example, during the first water intake process, a first preset conductivity is used as a benchmark value to detect whether the amount of foam in the drum is excessive. For instance, during the first water intake process, as water continues to enter and the clothes continue to absorb water, the sensor detects that the conductivity of the washing water exceeds the first preset conductivity. The first preset conductivity is, for example, equal to, but not limited to, 0.95*A0. If the conductivity of the washing water exceeds the first preset conductivity, it indicates that the conductivity of the washing water remains near A0. Because the detergent concentration is high during this process, it is impossible to determine whether the amount of foam in the drum is excessive at this time. Therefore, during subsequent water replenishment processes, it is necessary to continue detecting whether the amount of foam in the drum is excessive.

[0049] In some embodiments, when the conductivity of the washing water is less than a second preset conductivity during the first water intake process, it is determined that the amount of foam in the clothes processing equipment drum is less than or equal to the preset amount of foam.

[0050] Specifically, the second preset conductivity is the benchmark for determining whether the amount of foam in the washing machine drum during the first water intake process is less than or equal to a preset foam amount. For example, if the conductivity detected by the sensor during the first water intake process is less than or equal to the second preset conductivity, which is, for example, equal to but not limited to 0.9*A0, it indicates that the conductivity detected by the sensor decreases rapidly during the first water intake process. For example, if the conductivity detected by the sensor gradually decreases from A0 to, for example, 0.9*A0, it can be determined that the amount of foam generated in the washing machine drum during this process is small. Furthermore, it can be predicted that there will be no foam overflow in the washing machine drum. At this time, it can be determined that the amount of foam in the washing machine drum is less than or equal to the preset foam amount, that is, it is not excessive. In the subsequent water replenishment process of the washing machine, it is not necessary to continue to detect the conductivity of the washing water to determine whether the amount of foam in the washing machine drum is excessive.

[0051] S103. Detect whether the amount of foam in the cylinder exceeds the preset amount of foam based on the conductivity corresponding to the water replenishment stage.

[0052] In some embodiments, the washing process includes multiple water replenishment processes. Based on the change in conductivity corresponding to the previous water replenishment stage from less than or equal to the first preset conductivity to greater than the first preset conductivity, the conductivity of the washing liquid in the drum when the garment processing device is in the next water replenishment stage is obtained. That is, based on the conductivity of the washing water being greater than the first preset conductivity during the first water intake, the conductivity of the washing water during the intermediate water replenishment process is obtained; based on the change in conductivity corresponding to the intermediate water replenishment process from less than or equal to the first preset conductivity to greater than the first preset conductivity, the conductivity of the washing water when the garment processing device enters the next water replenishment stage is obtained.

[0053] Specifically, when the washing process includes multiple water replenishment processes, the washing process includes one or more intermediate water replenishment processes and a final water replenishment process after the first water intake process. If the conductivity of the washing water during the first water intake is greater than a first preset conductivity (e.g., 0.95*A0), it is necessary to determine whether the foam quantity is excessive based on the conductivity of the subsequent water replenishment processes. Specifically, if the conductivity of the washing water is detected to temporarily drop to, for example, less than or equal to, the first preset conductivity, but quickly returns to a level greater than the first preset conductivity (e.g., returning to full capacity A0), it is still impossible to determine whether the foam quantity in the garment processing equipment drum is excessive during this intermediate water replenishment process. Therefore, it is necessary to continue detecting whether the foam quantity in the garment processing equipment drum is excessive during subsequent water replenishment processes.

[0054] In some embodiments, detecting whether the amount of foam in the garment processing device drum is excessive based on the conductivity obtained during the water replenishment process includes: determining that the amount of foam in the drum is greater than the preset foam amount based on the conductivity corresponding to the previous water replenishment stage being greater than the first preset conductivity; and determining that the amount of foam in the drum is less than or equal to the preset foam amount based on the conductivity corresponding to the previous water replenishment stage being less than the third preset conductivity. That is, when the conductivity corresponding to the intermediate water replenishment exceeds the first preset conductivity, it is determined that the amount of foam in the garment processing device drum is greater than the preset foam amount; when the conductivity corresponding to the intermediate water replenishment process does not reach the third preset conductivity, it is determined that the amount of foam in the garment processing device drum is less than or equal to the preset foam amount; wherein, the first preset conductivity is greater than the third preset conductivity.

[0055] Specifically, during the intermediate water replenishment process of the garment processing equipment, if the conductivity detected by the sensor is greater than a first preset conductivity (e.g., but not limited to 0.95*A0), it can be determined that excessive foam is generated inside the garment processing equipment. This can then predict whether foam overflow or interference with the subsequent dehydration process will occur. A third preset conductivity can be set for the water replenishment process of the garment processing equipment. This third preset conductivity serves as a benchmark for determining whether the amount of foam inside the garment processing equipment is less than or equal to a preset foam amount during the water replenishment process. Specifically, during the intermediate water replenishment process, if the conductivity of the washing water is detected to be less than the third preset conductivity, it can be determined that excessive foam will not be generated inside the garment processing equipment. If the second preset conductivity is greater than the third preset conductivity (e.g., but not limited to 0.8*A0), and the conductivity of the washing water continuously decreases until it falls below the third preset conductivity, it can be determined that excessive foam will not be generated inside the garment processing equipment, at which point the foam amount determination process ends.

[0056] It should be noted that the specific values ​​of the first, second, and third preset conductivity values ​​are not limited in this embodiment. The first preset conductivity can be greater than or equal to the second preset conductivity. Furthermore, when the conductivity corresponding to the intermediate water replenishment process exceeds the first preset conductivity, it is determined that the amount of foam inside the garment processing equipment is excessive; when the conductivity corresponding to the intermediate water replenishment process is less than the third preset conductivity, it is determined that the amount of foam inside the garment processing equipment is less than or equal to a preset foam amount. This method is applicable to washing processes that include one water replenishment process or multiple water replenishment processes.

[0057] In some embodiments, if the conductivity corresponding to the last water replenishment process exceeds a first preset conductivity, it is determined that the amount of foam inside the garment processing device is greater than a preset foam amount; if the conductivity corresponding to the last water replenishment process does not reach a third preset conductivity, it is determined that the amount of foam inside the garment processing device is less than or equal to a preset foam amount. For example, the statement that the conductivity corresponding to the last water replenishment stage is greater than the first preset conductivity includes: the conductivity corresponding to the last water replenishment stage continuously being greater than the first preset conductivity, or the conductivity corresponding to the last water replenishment stage changing from less than or equal to the first preset conductivity to being greater than the first preset conductivity.

[0058] Specifically, during the final water intake, if the conductivity detected by the sensor is greater than a first preset conductivity, such as, but not limited to, 0.95*A0, or if the conductivity corresponding to the final water replenishment stage remains greater than 0.95*A0, or if the conductivity corresponding to the final water replenishment stage first drops to less than 0.95*A0 and then exceeds 0.95*A0 again after a period of time, such as reaching a peak value of A0, it can be determined that there is excessive foam generated inside the garment processing equipment. This can then be predicted that foam overflow or the subsequent dehydration process may occur inside the garment processing equipment. If the conductivity of the washing water detected by the sensor does not reach a third preset conductivity, such as, but not limited to, 0.8*A0, or if the conductivity continues to decrease and drops to less than the third preset conductivity, it can be determined that there will not be excessive foam generated inside the garment processing equipment, and the foam amount judgment process ends at this time.

[0059] It should be noted that when the washing process includes one water replenishment process, the logic for determining the amount of foam during the water replenishment process also applies to the logic for determining the amount of foam during the last water replenishment process; when the washing process includes two water replenishment processes, the logic for determining the amount of foam during the first water replenishment process also applies to the logic for determining the amount of foam during the intermediate water replenishment process, and the logic for determining the amount of foam during the second water replenishment process also applies to the logic for determining the amount of foam during the last water replenishment process; when the washing process includes three water replenishment processes, the logic for determining the amount of foam during the first and second water replenishment processes also applies to the logic for determining the amount of foam during the intermediate water replenishment process, and the logic for determining the amount of foam during the third water replenishment process also applies to the logic for determining the amount of foam during the last water replenishment process, and so on. Further details will not be elaborated here.

[0060] In some embodiments, after determining that the amount of foam inside the garment processing equipment is excessive, the foam can be defoamed by letting it stand or by heating.

[0061] Specifically, based on the judgment that excessive foam is generated inside the garment processing equipment, it can be predicted that foam overflow or problems affecting the subsequent dehydration process will occur. To solve this problem, the foam can be eliminated by allowing the equipment to stand for a preset time to automatically defoam. Alternatively, it can be eliminated by heating, such as heating the inner drum of the garment processing equipment. The garment processing equipment is equipped with a heating structure, and the specific implementation and installation location of the heating structure are not limited in this embodiment. Alternatively, both standing and heating methods can be used simultaneously to eliminate foam and accelerate the defoaming process; this embodiment is not specifically limited in this regard.

Taking the water replenishment stage, which includes a first water replenishment stage and a second water replenishment stage, as an example... Figure 2 As shown, foam detection methods include:

[0071] S208. Determine whether D1 decreased and then changed to be greater than 0.95*A0. If yes, execute S210; if no, execute S209.

[0072] Specifically, whether D1 decreases and then changes back to be greater than 0.95*A0 can be determined by whether D1 decreases to less than 0.95*A0 and then increases back to be greater than 0.95*A0 during the first water intake stage.

[0073] S209. Determine if D1 is less than 0.8*A0. If yes, execute S213; otherwise, execute S205.

[0077] S213, End.

[0078] With the widespread use of garment cleaning equipment in daily life, people use these devices almost every day. Sometimes, users add too much detergent, leading to excessive foam production during operation. This foam can overflow from the detergent dispenser or interfere with the subsequent spin-drying process, causing significant inconvenience. Currently, the presence of excessive foam in the garment cleaning equipment can be detected during the drainage process before the spin-drying begins. However, this technology often detects foam buildup before it is detected, still causing problems for users.

[0079] This embodiment improves the detection time of conductivity by acquiring conductivity as soon as the garment processing equipment enters the washing process, before a large amount of foam has formed in the equipment. Based on the change in conductivity, it anticipates whether the amount of foam inside the garment processing equipment is excessive during the washing process. This allows for the prediction of foam generation inside the garment processing equipment during the washing process, solving the problem of excessive foam generation before it is detected, which causes user inconvenience. It effectively reduces the situation where excessive foam overflows from the detergent dispenser or affects the subsequent dehydration process, thus optimizing the user experience.

[0080] Based on the same inventive concept, this disclosure also provides a foam detection device. Figure 3 This is a schematic diagram of the structure of a foam detection device provided in an embodiment of this disclosure, as shown below. Figure 3As shown, the device includes: a first conductivity acquisition module 31, used to acquire the conductivity of the washing liquid in the drum when the laundry processing equipment is in the first water intake stage; a second conductivity acquisition module 32, used to acquire the conductivity of the washing liquid in the drum when the laundry processing equipment is in the water replenishment stage based on the conductivity corresponding to the first water intake stage being greater than a first preset conductivity; and a foam quantity detection module 33, used to detect whether the foam quantity in the drum exceeds a preset foam quantity based on the conductivity corresponding to the water replenishment stage.

[0081] Specifically, the garment processing equipment may include a sensor, such as a conductivity sensor, which can be installed at the bottom of the outer drum of the garment processing equipment. This ensures that the sensor is always in contact with the washing water (the liquid used for washing) during the washing process, allowing the sensor to detect the conductivity of the washing water. Specifically, the conductivity of the washing water during the washing process can be obtained, either in real-time (continuously) or at set intervals. This allows for obtaining the conductivity of the washing water during the washing process while effectively reducing the power consumption of the garment processing equipment for conductivity detection. The washing process may include a first water intake process and a water replenishment process; alternatively, it may include a first water intake process and multiple water replenishment processes, with the water replenishment process occurring after the water intake process.

[0082] Specifically, the conductivity of the washing water is related to the detergent concentration. For example, the higher the detergent concentration, the greater the conductivity; conversely, the lower the detergent concentration, the lower the conductivity. Higher detergent concentrations result in more foam being generated inside the garment processing equipment, while lower concentrations result in less foam. Based on this logic, the conductivity of the washing water is positively correlated with the amount of foam generated inside the garment processing equipment; that is, the higher the conductivity, the more foam is generated, and vice versa. For example, the garment processing equipment's memory can pre-store a table corresponding to the conductivity and the amount of foam generated inside. After obtaining the conductivity during the washing process, the amount of foam inside the equipment can be determined by looking up the table. Therefore, the amount of foam generated inside the washing machine drum can be detected by obtaining the conductivity of the washing water, thus determining whether the amount of foam generated inside the garment processing equipment is excessive.
