[0002] With the development of washing machine technology, washing machines have become an increasingly common household appliance. Most washing machines have stainless steel inner drums. Therefore, a common problem in life is that metal foreign objects in clothes constantly collide with the inner drum during the washing process, producing a harsh noise, which can wear down clothes, damage the washing machine, and even cause safety accidents.

[0003] In existing technologies, foreign objects inside clothes can be detected by a metal detector and an electronic product detector installed at the washing machine opening before washing. Alternatively, a sound detection device can be installed to detect sound information inside the washing machine drum during the washing process to determine whether there are any metal foreign objects.

[0004] However, using an installation device to detect foreign objects inside the washing machine drum is costly and requires manual removal of the foreign objects. If the metal foreign objects are wrapped in a large number of clothes, the accuracy of the detection is reduced, and it may still cause varying degrees of damage to the clothes and the inner drum. Summary of the Invention

[0073] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0074] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0075] The application scenarios of the embodiments of this application are explained below:

[0076] Figure 1 This is an application scenario diagram of a washing machine control method provided in an embodiment of this application, such as... Figure 1 As shown, the scenario includes a washing machine 101, a user 102, a washing tub 103, and laundry 104. The laundry 104 contains a metallic foreign object, such as a set of keys. When the user 102 needs to do laundry, the user 102 can place the laundry 104 into the washing tub 103 of the washing machine 101 and operate the washing machine 101 to do laundry. However, since the laundry 104 contains keys, it may cause varying degrees of damage to the laundry 104 itself and the washing tub 103.

[0077] The washing machine can be a drum washing machine, an agitator washing machine, a pulsator washing machine, etc., and this application embodiment does not specifically limit it.

[0078] In some technologies, foreign objects inside clothes can be detected by metal detectors and electronic device detectors installed at the washing machine opening before washing. Alternatively, sound detection devices can be installed to detect sound information inside the washing machine drum during the washing process to determine whether there are any metal foreign objects.

[0079] However, using an installation device to detect foreign objects inside the washing machine drum is costly and requires manual removal of the foreign objects. If the metal foreign objects are wrapped in a large number of clothes, the accuracy of the detection is reduced, and it may still cause varying degrees of damage to the clothes and the inner drum.

[0080] To address the aforementioned issues, this application provides a washing machine control method. This method can detect the sound frequency inside the washing machine drum in real time and further check whether the sound frequency exceeds a frequency threshold. If the sound frequency exceeds the frequency threshold multiple times consecutively, it is determined that there is a metal foreign object inside the washing machine drum. This is because if there is a metal foreign object (such as a coin or a metal zipper on clothing) inside the drum, the metal foreign object will continuously collide with the stainless steel inner drum during rotation, generating a harsh noise. The sound frequency generated at this time will exceed the frequency threshold. Furthermore, by controlling the washing motor to reduce the speed to weaken the water flow intensity by one level and controlling the water inlet valve to increase the water level inside the washing machine drum, frictional resistance is reduced, thereby reducing damage to the clothes and the washing machine drum.

[0081] For example, Figure 2 This is a flowchart illustrating a washing machine control method provided in an embodiment of this application, as shown below. Figure 2 As shown, the washing machine control method includes the following steps:

[0082] S201. Obtain the sound frequency of the washing machine drum during the washing process.

[0083] In this step, the sound frequency of the washing machine drum can be detected in real time by a sound sensor. This sound frequency can be the sound frequency of the clothes hitting the drum. Furthermore, the sound sensor converts the detected sound frequency into a voltage signal and transmits it to the main control chip (i.e., the controller). Accordingly, the main control chip can obtain the sound frequency of the washing machine drum during the washing process.

[0084] For example, in Figure 1 In the application scenario, after user 102 places the laundry 104 into the washing tub 103 of washing machine 101, the washing program of washing machine 101 is started. Furthermore, washing machine 101 can obtain the sound frequency of washing tub 103 during the washing process in real time.

[0085] S202. Determine whether the sound frequency meets the preset requirements.

[0086] In this embodiment of the application, the preset requirement may refer to the number of times the sound frequency is greater than the frequency threshold; or it may refer to the duration of the sound frequency being greater than the frequency threshold being greater than the time threshold. Here, the frequency threshold may refer to the set sound frequency at which the metal foreign object may hit the washing machine drum, for example, the frequency threshold is 2000HZ; the number of times threshold may refer to the set number of times the metal foreign object can be determined to be in the washing machine drum, for example, the number of times threshold can be 3 times; the time threshold may refer to the set time period during which the metal foreign object can be determined to be in the washing machine drum, for example, the time threshold can be 1 minute.

[0087] Understandably, when there are no metal foreign objects in the washing machine drum, the sound sensor typically detects a sound frequency range between 100-2000 Hz during normal washing. When there are metal foreign objects inside the drum, they will continuously collide with the stainless steel inner drum during rotation, generating a harsh noise. The resulting sound frequency will exceed 2000 Hz. Therefore, this application specifies that if the sound frequency detected in the washing machine drum during the washing process exceeds a frequency threshold, a metal foreign object may be present. By setting the sound frequency to exceed the frequency threshold multiple times or for an extended period to confirm the presence of a metal foreign object, the accuracy of detection can be improved.

[0088] For example, in Figure 1 In the application scenario, the washing machine 101 determines whether the number of times the sound frequency is greater than 2000HZ reaches the requirement of 3 based on the real-time acquired sound frequency. Furthermore, the washing machine 101 performs corresponding operations based on the judgment result.

[0089] S203. If the preset requirements are met, it is determined that there is a metal foreign object in the tub, and the water flow intensity in the tub of the washing machine is reduced, and the water level in the tub of the washing machine is increased.

[0090] In this embodiment, the water flow intensity can refer to the force of the washing water impacting the clothes per unit time, and the water flow intensity can be changed by controlling the speed of the washing motor; the water level can refer to the height of the water surface relative to the bottom base of the washing machine, and the water level in the washing machine drum can be raised or lowered by adjusting the water inlet valve or the water outlet valve.

[0091] For example, in Figure 1 In the application scenario, if the washing machine 101 determines that the sound frequency is greater than 2000HZ more than 3 times, it is determined that there is a metal foreign object in the washing tub 103. Furthermore, by controlling the washing motor to reduce the speed, the water flow intensity is reduced by one level, and by controlling the water inlet valve to introduce water at one water level, the water level in the washing tub 103 is increased.

[0092] It should be noted that the metal foreign object can be a metal object that is inherent to the clothing itself, such as a zipper or decoration, or a metal foreign object that the user accidentally puts into the bucket, such as a key, coin, power bank, or earphone. This application does not limit the specific form of the metal foreign object.

[0093] Therefore, the washing machine control method proposed in this application can detect foreign objects in the washing machine drum by sound frequency. After confirming the presence of foreign objects, it is not necessary to remove them manually immediately. Instead, by reducing the water flow intensity and raising the water level, the clothes are submerged in the water, reducing frictional resistance and thus reducing damage to the clothes and the inner drum. This improves convenience and enhances the user experience.

[0094] Optionally, if preset requirements are met, it is determined that there is a metal foreign object in the tub, and the water flow intensity inside the washing machine tub is reduced, while the water level inside the washing machine tub is increased, including:

[0095] If the number of times the sound frequency is greater than the frequency threshold reaches the first threshold, then it is determined that there is a metallic foreign object in the barrel.

[0096] After determining that there is a metal foreign object in the barrel, a first target rotational speed is determined based on the current rotational speed, and a first target water level is determined based on the current water level; wherein, the first target rotational speed is less than the current rotational speed, and the first target water level is greater than the current water level;

[0097] Control the water inlet valve to allow water to enter to the first target water level; and adjust the speed of the washing machine to the first target speed.

[0098] In this embodiment of the application, the first count threshold can refer to the number of times the washing machine system can determine the presence of metal foreign objects in the washing machine drum. For example, the first count threshold can be 3 times. It is understood that the first count threshold can also be modified manually, and this embodiment of the application does not specifically limit it.

[0099] The first target rotation speed can refer to the number of revolutions the washing machine system sets around the center of the circumference per unit time, which is less than the current rotation speed of the washing machine; the first target water level can refer to the water level set by the washing machine system to be greater than the current water level of the washing machine by injecting water.

[0100] It is understood that the first target rotational speed may be lower than the current rotational speed by one or more levels, and the first target water level may be higher than the current water level by one or more levels. This application does not specifically limit this.

[0101] It should be noted that controlling the water inlet valve to allow water to enter to the first target water level is used to raise the water level inside the washing machine drum; adjusting the washing machine speed to the first target speed is used to reduce the water flow intensity inside the washing machine drum.

[0102] For example, in Figure 1In the application scenario, if the washing machine 101 detects a sound frequency greater than 2000 Hz three times, it is determined that there is a metal foreign object in the washing tub 103. Furthermore, after determining that there is a metal foreign object in the washing tub 103, the washing machine 101 can determine the first target speed as 400 rpm based on the current speed of the washing machine 101 (800 rpm) and the first target water level as 80 cm based on the current water level of the washing machine 101 (60 cm). Further, based on the first target water level of 80 cm, the washing machine 101 controls the water inlet valve to allow water to enter to a depth of 80 cm in the washing tub 103 of the washing machine 101; based on the first target speed of 400 rpm, the speed of the washing machine 101 is adjusted to 400 rpm.

[0103] It should be noted that the specific values ​​mentioned in the embodiments of this application are merely illustrative examples, and the embodiments of this application do not limit the magnitude of the specific values.

[0104] Therefore, the embodiments of this application can reduce the resistance of friction and impact by controlling the washing motor to reduce the water flow intensity and controlling the water inlet valve to raise the water level in the washing machine drum, thereby reducing damage to clothes and the washing drum and protecting the user's property.

[0105] Optionally, the method further includes:

[0106] After reducing the water flow intensity and raising the water level, it is determined whether the number of times is greater than the second number threshold; the first number threshold is less than the second number threshold.

[0107] If so, the washing machine's rotation speed is adjusted to the second target rotation speed, and the water inlet valve is controlled to allow water to enter to the second target water level; wherein, the second target rotation speed is less than the first target rotation speed, and the second target water level is greater than the second target water level;

[0108] If not, the washing program of the washing machine is run based on the first target rotation speed and the first target water level.

[0109] In this embodiment, the second threshold number can refer to the number of times the washing machine system can determine the presence of a metallic foreign object in the washing machine drum. However, this number is to determine whether the sound frequency will still exceed the frequency threshold after the water flow intensity is reduced once and the water level is increased once. The second threshold number is greater than the first threshold number. For example, the second threshold number can be 6 times. It is understood that the second threshold number can also be modified manually. This embodiment does not specifically limit this.

[0110] In this step, setting a second threshold is to address the situation where reducing the water flow intensity once and raising the water level once does not reduce the harsh noise.

[0111] The second target rotation speed can refer to the number of revolutions the washing machine system sets around the center of the circumference per unit time that is less than the first target rotation speed; the second target water level can refer to the height of the water level set by the washing machine system to be greater than the first target water level by the amount of water injected.

[0112] For example, in Figure 1 In the application scenario, after the washing machine 101 reduces the water flow intensity once and raises the water level once, it will continue to judge whether the number of times the sound frequency is greater than 2000HZ is greater than 6. If so, based on the first target speed of 400 rpm, the speed of the washing machine 101 will be adjusted to the second target speed of 200 rpm, and based on the first target water level of 80cm, the water inlet valve will be controlled to fill water to the second target water level of 100cm. If not, the washing program of the washing machine 101 will be run based on the first target speed of 400 rpm and the first target water level of 80cm.

[0113] Therefore, this application reduces frictional resistance by repeatedly performing operations to reduce water flow intensity and raise water level, so that the clothes are completely submerged in water, thereby reducing damage to the clothes themselves and the washing drum. No manual intervention is required, saving labor time and effort.

[0114] Optionally, the method further includes:

[0115] If, after running the washing program of the washing machine based on the second target rotation speed and the second target water level, the sound frequency is detected to be greater than the frequency threshold again, the washing program of the washing machine will be terminated and a first alarm message will be sent to prompt the user to remove the metal foreign object from the drum.

[0116] In this embodiment, the first alarm message can refer to an alarm message used to alert the user that the washing program of the washing machine has malfunctioned, i.e., that a metal foreign object has been generated in the washing machine drum. The method of sending the first alarm message is not specifically limited in this embodiment. It can be to display a message box on the display screen of the washing machine, which displays "There is a metal foreign object in the washing machine drum" to prompt the user to remove the metal foreign object in the drum in time. Alternatively, the washing machine can send a message to the user terminal device connected to the washing machine, which also displays "There is a metal foreign object in the washing machine drum" to prompt the user to remove the metal foreign object in the drum in time.

[0117] In one possible implementation, the first alarm message may also be sent in the form of a piece of music or a warning light. This application embodiment does not specifically limit the form of the first alarm message.

[0118] For example, in Figure 1In the application scenario, if the washing machine 101 runs the washing program based on the second target speed of 200 rpm and the second target water level of 100 cm, and then detects a sound frequency greater than 2000 Hz again, the washing program of the washing machine 101 will be terminated, and a first alarm message will be sent to the user 101's terminal device. The first alarm message is "There is a metal foreign object in the washing machine drum", so as to prompt the user 101 to remove the metal foreign object from the drum.

[0119] Therefore, in this embodiment of the application, if the sound frequency still exceeds the frequency threshold after repeatedly reducing the water flow intensity in the washing machine drum and raising the water level in the washing machine drum, the washing machine operation program is terminated and an alarm message is sent. The damage to the clothes and the inner drum is reduced by manually removing the metal foreign object, thus improving the flexibility of the process.

[0120] Optionally, the method further includes:

[0121] The system obtains the user's input command to start the washing process and determines whether there are any metal foreign objects in the clothes inside the drum based on the images of the clothes captured by the camera module.

[0122] If so, the washing machine will stop working, the washing machine door will be opened, and a prompt message will be sent to the user;

[0123] If not, then start the washing program of the washing machine.

[0124] In this embodiment of the application, the camera module can refer to a functional module used to capture images of clothing and perform metal foreign object identification, for example, Figure 3 This application provides a schematic diagram of a washing machine structure with a camera module, as shown in the embodiment. Figure 3 As shown, a camera module 301 is installed inside the washing machine 101. The camera module 301 can detect foreign objects based on image recognition technology. Specifically, the camera module 301 can take pictures of the clothes inside the washing machine 101 and determine whether there are foreign objects in the washing machine 101 based on the pictures. Foreign objects refer to materials other than the material of the clothes and the materials of the clothes. If the camera module 301 detects that there are foreign objects in the washing machine 101, it sends a prompt message to the user's terminal device to remind the user that there are foreign objects in the washing machine 101. These foreign objects include metal foreign objects.

[0125] It should be noted that the specific location of the camera module 301 is not limited in the embodiments of this application, and can be any location. Figure 3 The location shown can also be other locations, as long as the placement position can capture an image of the entire inside of the washing machine drum.

[0126] It is understood that the above image recognition process can be integrated into the camera module 301 or completed by the controller of the washing machine 101. This application embodiment does not specifically limit this.

[0127] In this step, the prompt message can refer to a message sent before the washing machine starts to inform the user that a metal foreign object has been generated in the washing machine drum. The method of sending the prompt message is not specifically limited in this embodiment. It can be a message prompt box displayed on the screen of the washing machine, showing "A metal foreign object exists in the washing machine drum, as shown in picture 1," allowing the user to see the specific location of the metal foreign object and prompting the user to remove it from the drum in time. Alternatively, the washing machine can send a message prompt to the user's terminal device connected to the washing machine, stating "A metal foreign object exists in the washing machine drum, as shown in picture 1," allowing the user to see the specific location of the metal foreign object and prompting the user to remove it from the drum in time.

[0128] For example, in Figure 1 In the application scenario, when the washing machine 101 receives the washing start command input by the user 102, it can first determine whether there are any metal foreign objects in the clothes in the washing tub 103 based on the image of the clothes captured by the camera module; if so, it controls the washing machine 101 to stop working and opens the door of the washing machine 101, and further sends a prompt message to the user, which is "There are metal foreign objects in the washing machine tub, as shown in picture 1"; if not, it starts the washing program of the washing machine 101 to wash the clothes.

[0129] Therefore, when washing clothes, the method provided in this application embodiment can also detect whether there are foreign objects in the clothes in advance, and can remind the user in time before the user leaves, thus improving convenience and timeliness.

[0130] Optionally, the method provided in this application embodiment can detect the sound frequency of the washing machine tub using a sound sensor, detect the water level inside the washing machine tub using a water level sensor, and detect the rotation speed of the washing machine using a motor.

[0131] In this step, the sound sensor can be used to receive sound waves, display the vibration image of the sound, and detect the sound frequency; the water level sensor can refer to an instrument that converts the water level parameter of the measured point into a corresponding electrical signal in real time, and is used to detect the water level in the washing machine drum; the motor can refer to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. In this embodiment, it is a washing motor, used to detect the rotation speed of the washing machine.

[0132] For example, in Figure 1In the application scenario, the washing machine 101 can detect the sound frequency of the washing tub 103 in real time through the sound sensor, detect the water level in the washing tub 103 through the water level sensor, and detect the rotation speed of the washing machine 101 through the motor. Furthermore, the controller of the washing machine 101 obtains the above data.

[0133] Therefore, the embodiments of this application obtain the corresponding parameter data through the various module devices in the washing machine without mutual interference, thereby improving the accuracy of the obtained data.

[0134] Optionally, the method further includes:

[0135] If it is determined that there is a metal foreign object in the bucket, the total weight of the clothes in the bucket is obtained by a weighing device, and the metal foreign object or the clothes carrying the metal foreign object is sucked into the bucket of the foreign object isolation device through the foreign object isolation device.

[0136] The bucket door of the foreign object isolation device is closed to isolate the metal foreign object or clothing carrying the metal foreign object in the foreign object isolation device, and the weight of the remaining clothing in the bucket is weighed using the weighing device.

[0137] If it is determined that the difference between the total weight and the weight of the remaining clothes is less than or equal to a preset threshold, then the washing program of the washing machine continues to be executed.

[0138] If the difference between the total weight and the weight of the remaining clothes is determined to be greater than a preset threshold, the washing program of the washing machine is terminated, and a second alarm message is sent to prompt the user to remove the metal foreign object or the clothes carrying the metal foreign object from the foreign object isolation device.

[0139] In this embodiment, the weighing device is used to weigh the clothes inside the washing machine drum, and the foreign object isolation device is used to suck in metal foreign objects or clothes carrying metal foreign objects, and to isolate the metal foreign objects or clothes carrying metal foreign objects from other clothes inside the washing machine drum. For example, Figure 4 This application provides a schematic diagram of a washing machine structure with a foreign object isolation device and a weighing device, as shown in the embodiment of the present application. Figure 4 As shown, a foreign object isolation device 401 is installed inside the washing machine 101, and a weighing device 403 is installed at the bottom of the washing machine 101. The foreign object isolation device 401 also has a drum door 402 installed within it. It is understood that this embodiment does not limit the specific installation locations of the foreign object isolation device 401 and the weighing device 403; they can be... Figure 4 The location shown can also be other locations, as long as the installation location can achieve its corresponding function.

[0140] The preset threshold can refer to a reasonable weight set for judging metal foreign objects or clothing carrying metal foreign objects. That is, if the difference between the total weight and the weight of the remaining clothing is too large, it is considered that there are other clothing mixed with metal foreign objects or clothing carrying metal foreign objects in the foreign object isolation device. In this case, it is not recommended to perform the washing program. The preset threshold can be set to 0.1 kg. It is understood that the preset threshold can also be modified manually. This application embodiment does not specifically limit this. The explanation of the second alarm prompt information is similar to that of the first alarm prompt information, and will not be repeated here. For details, please refer to the description of the first alarm prompt information.

[0141] For example, in Figure 1 In application scenarios, with Figure 4 Taking the structure shown as an example, if the washing machine 101 determines that there is a metal foreign object in the washing tub 103, it uses the weighing device 403 to obtain the total weight of the clothes in the washing tub 103, which is 1 kg. Then, it uses the foreign object isolation device 401 to suck the key into the tub of the foreign object isolation device 401 and controls the tub door 402 of the foreign object isolation device 401 to close, thereby isolating the key in the foreign object isolation device 401. Further, the weighing device 403 is used to weigh the remaining clothes in the washing tub 103, and the weight is found to be 0.9 kg. It can be determined that the difference between the total weight of 1 kg and the weight of the remaining clothes of 0.9 kg is 0.1 kg, which is equal to the preset threshold of 0.1 kg. Then, the washing program of the washing machine 101 continues to be executed to wash the clothes.

[0142] Optionally, the weighing device 403 can be used to weigh the remaining clothes in the washing tub 103. If the weight is 0.6 kg, it can be determined that the difference between the total weight of 1 kg and the weight of the remaining clothes of 0.6 kg is 0.4 kg, which is greater than the preset threshold of 0.1 kg. Then, the washing program of the washing machine 101 is terminated, and a second alarm message is sent to the terminal device of the user 102. The second alarm message is "There is a metal foreign object in the foreign object isolation device", so as to prompt the user 102 to remove the metal foreign object from the foreign object isolation device.

[0143] Therefore, the method provided in this application embodiment can also isolate clothing or metal foreign objects carrying metal foreign objects during the washing process, reducing the occurrence of damage caused by frequent impacts during the washing process due to forgetting to remove valuable items. At the same time, it can reduce damage to clothing and the inner drum of the washing machine caused by hard metal foreign objects, and can also reduce the interruption of the washing process due to individual clothing carrying metal foreign objects, thus improving convenience.

[0144] Optionally, the method further includes:

[0145] The type of the metallic foreign object is determined based on the magnitude of the sound frequency, and the type of the metallic foreign object is sent to the user as a message prompt, so that the user can choose whether to remove the metallic foreign object from the barrel;

[0146] If the frequency of the sound is within a first preset range, then the metallic foreign object is determined to be a small or harmless foreign object.

[0147] If the sound frequency is within a second preset range, then the metallic foreign object is determined to be a large or harmful foreign object.

[0148] In this embodiment of the application, the first preset interval may refer to the range of sound frequency values ​​set by the system to determine that the metal foreign object causes less damage to the clothes or the inner drum of the washing machine, and the second preset interval may refer to the range of sound frequency values ​​set by the system to determine that the metal foreign object causes more damage to the clothes or the inner drum of the washing machine. In this embodiment of the application, the specific values ​​of the upper and lower limits of the first preset interval and the second preset interval are not limited. For example, the first preset interval may be [2001, 2100], and the second preset interval may be (2100, ∞).

[0149] It is understood that the first preset interval and the second preset interval can also be modified manually, and this application embodiment does not specifically limit this.

[0150] In this step, the type of metallic foreign object can be classified based on the material of the metallic foreign object or based on the degree of damage to the clothes and the inner drum of the washing machine. This application embodiment does not specifically limit this. Preferably, it can be classified as small or harmless foreign objects, that is, those that cause less damage to the clothes and the inner drum of the washing machine, and large or harmful foreign objects, that is, those that cause greater damage to the clothes and the inner drum of the washing machine.

[0151] It should be noted that the embodiments of this application do not specifically limit the method and content of the message prompt. The method can refer to the method of sending the first alarm prompt information, and the content can be similar to "the metal foreign object is a small or harmless foreign object, possibly a coin".

[0152] For example, in Figure 1In this application scenario, the washing machine 101 can determine the type of the metal foreign object based on the frequency of the sound, and send the type of the metal foreign object to the user 102 as a message prompt, so that the user 102 can choose whether to remove the metal foreign object from the washing tub 103. For example, if the washing machine 101 detects that the sound frequency is 2021 Hz, it can determine that it is located in the first preset interval [2001, 2100], and it can determine that the existing metal foreign object is a small or harmless foreign object, which may be a zipper. Furthermore, the washing machine 101 can send a message prompt to the user 102's terminal device, which is "The metal foreign object is a small or harmless foreign object, possibly a zipper". After seeing the message prompt, the user 102 can choose not to remove the metal foreign object.

[0153] Optionally, if the washing machine 101 detects that the sound frequency is 3200 Hz, it can determine that the sound is located in the second preset range (2100, ∞), and it can be determined that the existing metal foreign object is a large or harmful foreign object. Based on the sound frequency, it can be preliminarily determined that it may be an electronic device. Furthermore, the washing machine 101 can send a message to the user 102's terminal device, which reads "The metal foreign object is a large or harmful foreign object, possibly an electronic device". After seeing the message, the user 102 can remove the metal foreign object in a timely manner.

[0154] Therefore, the method provided in this application embodiment can also determine the type of metal foreign object by the magnitude of the sound frequency, thereby providing a reference for users, enabling users to choose whether to remove the metal foreign object based on its type, improving the accuracy of the judgment, reducing damage to clothes and washing machines, enhancing the user experience, and also increasing the service life of the washing machine.

The aforementioned program can be stored in a computer-readable storage medium.
