Technical Field

[0002] This disclosure relates to the field of garment processing technology, and in particular to control methods, control devices, and garment processing equipment. Background Technology

[0003] Internally, garment processing equipment relies on high-voltage wiring harnesses to transmit power to various electrical components and low-voltage wiring harnesses to transmit response signals. As the equipment operates, interference can occur between these harnesses, leading to lower safety standards. Therefore, wireless power supply to the components within garment processing equipment has attracted considerable attention.

[0004] Currently, wireless power transmission in garment processing equipment uses electromagnetic induction between the receiving coil and the transmitting coil for energy and data transmission. However, when the receiving coil and the transmitting coil are working, foreign objects, especially metal objects, may fall between them, creating a shielding effect. This can affect the energy and data transmission between the receiving coil and the transmitting coil, causing the wireless power supply receiving module to be unable to supply power to the appliance normally, thus affecting the normal operation of the garment processing equipment.

[0005] When receiving and transmitting coils transmit energy and data, the transmission efficiency may be too low due to external environmental factors or installation defects, failing to meet the needs of electrical appliances and causing clothing processing equipment to malfunction. Therefore, a method to detect and improve transmission efficiency is urgently needed. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] The technical problem to be solved by this disclosure is to avoid the presence of foreign objects in the working environment of the wireless power supply transmitting module and the wireless power supply receiving module, which would affect the normal power supply of the wireless power supply receiving module to the electrical appliance and thus affect the normal use of the clothing processing equipment; and to avoid the problem that when the receiving coil and transmitting coil transmit energy and data, the transmission efficiency is too low due to the influence of the external environment or installation defects, which would fail to meet the needs of the electrical appliance and cause the clothing processing equipment to malfunction.

[0081] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions in the embodiments of this disclosure will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0082] In related technologies, wireless power transmission in dryers uses electromagnetic induction between the receiving coil and the transmitting coil for energy and data transmission. However, when the receiving coil and the transmitting coil are working, foreign objects, especially metal objects, may fall between the receiving coil and the transmitting coil, creating a shielding effect. This can affect the energy transmission and data transmission between the receiving coil and the transmitting coil, causing the wireless power supply receiving module to be unable to supply power to the appliance normally, thus affecting the normal operation of the clothing processing equipment.

[0083] To detect whether the receiving coil and transmitting coil are operating normally, this disclosure provides a control method for a garment processing device. Figure 1 is a flowchart illustrating the control method for a garment processing device provided in this disclosure. This method can be executed by the control device of the garment processing device provided in this disclosure. The control device can be mounted on the mainboard of the garment processing device and can be implemented in software and / or hardware. As shown in Figure 1, the method includes the following steps:

[0084] S101. Based on the received signal from the wireless power supply receiving module, determine the received signal parameter information.

[0085] Figure 2 is a schematic diagram of the physical structure of a garment processing device provided in an embodiment of this disclosure. Exemplarily, as shown in Figure 2, the garment processing device may include a wireless power transmission module and a wireless power reception module. The wireless power transmission module and the wireless power reception module may include, for example, a wireless power reception module 3 and a wireless power transmission module 2. The wireless power transmission module 2 is disposed on the casing of the garment processing device, for example, on the back panel of the housing 5. The wireless power reception module 3 is disposed on the garment processing drum 1 of the garment processing device, and is used to supply power to the first electrical appliance 4 on the garment processing device. This embodiment of the disclosure does not limit the number or type of the first electrical appliance 4.

[0086] The wireless power transmission module 2 and the wireless power receiving module 3 transmit electrical energy without contact, meaning that they can transmit power without wires. For example, the aforementioned clothing processing device also includes a support shaft 6, which connects the housing 5 and the clothing processing drum 1, thereby driving the clothing processing drum 1 to rotate around its own support shaft 6.

[0087] The wireless power supply transmitting module 2 includes a transmitting coil and a first control board. The wireless power supply receiving module 3 may include, for example, a receiving coil and a second control board. Both the transmitting and receiving coils are arranged around the support shaft 6. Energy can be transferred between the transmitting and receiving coils via a magnetic field. For example, the first control board converts 220V AC to 12V AC and supplies power to the transmitting coil. When the transmitting coil is energized, it generates a changing magnetic field. The receiving coil can generate current through electromagnetic induction, thereby realizing energy transfer. This allows the wireless power supply receiving module 3 and the wireless power supply transmitting module 2 to still supply power to the first electrical appliance 4 even when the clothes handling drum 1 is rotating.

[0088] The second control board in the wireless power supply receiver module 3 modulates the current generated by the receiving coil to obtain parameters such as amplitude, phase, frequency, or quality factor (Q value) corresponding to the current information, which will not be listed here.

[0089] In addition, the wireless power supply receiving module 3 and the wireless power supply transmitting module 2 can also achieve bidirectional data transmission via carrier communication. The transmitting signal of the wireless power supply transmitting module 2 is modulated onto a high-frequency carrier signal and sent to the wireless power supply receiving module 3. The second control board in the wireless power supply receiving module 3 demodulates the high-frequency carrier signal to restore the original information, thereby obtaining the transmitting signal parameter information. The receiving signal of the wireless power supply receiving module 3 is modulated onto a high-frequency carrier signal and sent to the wireless power supply transmitting module 2. The first control board in the wireless power supply transmitting module 2 demodulates the high-frequency carrier signal to restore the original information and sends it to the main board of the garment processing equipment, whereby the main board of the garment processing equipment determines the received signal parameter information.

[0090] S102. Based on the received signal parameter information meeting the preset fault conditions, it is determined that there are foreign objects in the working environment of the wireless power supply transmitter module and the wireless power supply receiver module.

[0091] Specifically, if the mainboard of the garment processing equipment meets the preset fault conditions based on the received signal parameter information, it indicates that there are foreign objects in the working environment of the wireless power supply transmitter module and the wireless power supply receiver module. The foreign objects affect the transmission of power or data between the wireless power supply transmitter module and the wireless power supply receiver module. Therefore, it is determined that there are foreign objects in the working environment of the wireless power supply transmitter module and the wireless power supply receiver module.

[0092] In some embodiments, if foreign objects are detected in the operating environment of the wireless power supply transmitter and receiver modules during the inspection phase of the garment processing equipment on the production line, abnormal received signal parameter information can be stored and a prompt message can be generated to alert maintenance personnel to promptly repair the wireless power supply transmitter and receiver modules, preventing faulty garment processing equipment from entering the market. Exemplarily, the prompt message can be at least one of sound, light, or display prompts; this disclosure does not limit the scope of the prompt message.

[0093] In other embodiments, if foreign objects are detected in the operating environment of the wireless power supply transmitter and receiver modules during the user's use of the clothing processing equipment, abnormal received signal parameter information can be uploaded to the cloud, and prompt messages can be generated for both the user and the maintenance personnel in the background, so that the user and the maintenance personnel can promptly detect the faults of the clothing processing equipment.

[0094] It should be noted that the clothing processing equipment provided in the embodiments of this disclosure may be, for example, a washing machine, a dryer, or a washer-dryer combo, and the embodiments of this disclosure do not limit this.

[0095] This embodiment of the disclosure determines the presence of foreign objects in the operating environment of the wireless power supply transmitter and receiver modules by identifying the received signal parameter information and determining that the received signal parameter information meets preset fault conditions. By detecting the operating status of the wireless power supply transmitter and receiver modules, abnormal wireless power supply transmitter and receiver modules can be detected in a timely manner, thereby enabling timely repair. This avoids the problem that foreign objects in the operating environment of the wireless power supply transmitter and receiver modules can prevent them from supplying power to the first electrical appliance normally, thus affecting the normal use of the clothing processing equipment. This improves the user experience and enhances the reliability of the clothing processing equipment.

[0096] Optionally, based on the received signal meeting preset fault conditions, it is determined that there is foreign matter in the operating environment of the wireless power supply transmitter module and the wireless power supply receiver module, including: determining that there is foreign matter in the transmission channel of the wireless power supply receiver module and the wireless power supply transmitter module based on at least one of the following: the inductance value in the received signal parameter information is less than a preset inductance threshold, the resonant frequency in the received signal parameter information is greater than a preset frequency threshold, and the quality factor in the received signal parameter information is less than a preset quality factor threshold.

[0097] Specifically, there are foreign objects between the transmission channels of the wireless power supply receiving module and the wireless power supply transmitting module. For example, there are metallic foreign objects between the receiving coil and the transmitting coil. The metallic foreign objects will generate eddy currents, which will change the strength and separation of the electromagnetic field between the receiving coil and the transmitting coil. The receiving coil generates current based on the electromagnetic field. When the electromagnetic field changes, the current generated by the receiving coil will also change.

[0098] The wireless power receiving module can acquire current signals and determine their parameter information. The energy transmitted by the wireless power transmitting module is fixed. Due to obstruction by metallic foreign objects and the resulting eddy currents, the wireless power receiving module cannot receive energy normally, leading to a decrease in the inductance of the receiving coil, an increase in the resonant frequency, and a decrease in the quality factor (Q value). Therefore, based on at least one of the following parameters—inductance less than a preset inductance threshold, resonant frequency greater than a preset frequency threshold, and Q value less than a preset Q value threshold—it is determined that a foreign object exists in the transmission channel between the wireless power receiving module and the wireless power transmitting module.

[0099] It should be noted that the specific values ​​of the preset inductance threshold, preset frequency threshold, and quality factor threshold can all be set according to the actual power supply requirements of the wireless power supply transmitter module and the wireless power supply receiver module, and this embodiment does not limit them.

[0100] Optionally, the control method further includes: acquiring transmission signal parameter information of the transmission signal of the wireless power supply transmitting module; determining, based on the received signal parameter information meeting preset fault conditions, that there is foreign matter in the working environment of the wireless power supply transmitting module and the wireless power supply receiving module, including: determining, based on the transmission signal parameter information and the received signal parameter information, that the transmission efficiency is less than a preset efficiency threshold, and determining that there is foreign matter in the transmission channel of the wireless power supply transmitting module and the wireless power supply receiving module.

[0101] For example, the wireless power supply transmitting module sends the transmitting signal parameters to the wireless power supply receiving module, which also receives the receiving signal parameters. The wireless power supply receiving module obtains the output power of the receiving coil from the received signal parameters and the input power of the transmitting coil from the transmitting signal parameters. The wireless power supply receiving module sends the output power of the receiving coil and the input power of the transmitting coil to the mainboard of the garment processing device. The mainboard of the garment processing device determines the transmission efficiency between the receiving coil and the transmitting coil based on the ratio of the output power of the receiving coil to the input power of the transmitting coil. If the transmission efficiency is less than a preset efficiency threshold, it indicates that although the receiving coil and the transmitting coil can work, they cannot transmit normally, thus determining that there is a foreign object in the transmission channel between the wireless power supply transmitting module and the wireless power supply receiving module.

[0102] In some embodiments, such as misalignment of the receiving coil and transmitting coil due to initial installation deviation, since the transmitting coil is fixedly mounted on the housing of the garment processing device and the receiving coil is mounted on the garment processing drum, when the garment processing drum rotates and becomes eccentric, the receiving coil and transmitting coil cannot be perfectly aligned, or the distance between the receiving coil and transmitting coil is too large or too small, all of which will lead to a decrease in transmission efficiency. However, since the decrease in transmission efficiency caused by the misalignment of the receiving coil and transmitting coil is less than the decrease in transmission efficiency caused by foreign objects in the transmission channels of the wireless power supply transmitting module and the wireless power supply receiving module, a reasonable preset efficiency threshold can be set to distinguish between the decrease in transmission efficiency caused by falling metal foreign objects and the decrease in transmission efficiency caused by the misalignment of the receiving coil and transmitting coil, thereby avoiding misjudgment.

[0103] It should be noted that the preset efficiency threshold can be set according to the actual power supply requirements of the wireless power supply transmitting module and the wireless power supply receiving module. For example, the preset efficiency threshold can be the minimum efficiency at which the electrical energy generated by the wireless power supply receiving module can power the first electrical appliance. If the efficiency is less than this, the electrical appliance cannot be started. This embodiment does not limit the specific value of the preset efficiency threshold.

[0104] Optionally, determining that there is a foreign object in the operating environment between the wireless power supply transmitter module and the wireless power supply receiver module based on the transmission signal parameter information and the received signal parameter information indicates that the transmission efficiency is less than a preset efficiency threshold and this condition persists for a preset time. This includes determining that there is a foreign object in the transmission channel between the wireless power supply transmitter module and the wireless power supply receiver module based on the transmission signal parameter information and the received signal parameter information.

[0105] Specifically, when a foreign object exists between the transmission channels of the wireless power supply transmitter and receiver modules, the transmission efficiency will remain below a preset efficiency threshold for a certain period of time during the rotation of the garment processing drum because the foreign object is always present between the transmission channels, until the foreign object is removed. Conversely, low transmission efficiency caused by misalignment of the receiver and transmitter coils will change with the rotation of the garment processing drum and will not remain below the preset efficiency threshold for an extended period. Therefore, by determining the presence of a foreign object in the operating environment of the wireless power supply transmitter and receiver modules based on the transmission efficiency being below the preset efficiency threshold for a preset duration, we can distinguish between the reduced transmission efficiency caused by a fallen metal object and the reduced transmission efficiency caused by misalignment of the receiver and transmitter coils, thus avoiding misjudgment.

[0106] Optionally, the control method further includes: obtaining a prompt message from the wireless power supply transmitting module to determine that the wireless power supply receiving module has started abnormally; wherein the prompt message is generated when the wireless power supply transmitting module does not receive feedback information from the wireless power supply receiving module within a preset time.

[0107] For example, when the wireless power supply transmitting module and the wireless power supply receiving module are working normally, the wireless power supply receiving module sends feedback information to the wireless power supply transmitting module when it receives energy or data transmitted by the wireless power supply transmitting module. Upon receiving the feedback information, the wireless power supply transmitting module determines that the wireless power supply receiving module has started normally. If the wireless power supply transmitting module does not receive feedback information and sends a prompt information to the main control board of the garment processing equipment within a preset time, it indicates that the wireless power supply receiving module has started abnormally.

[0108] It should be noted that the preset time can be set according to the actual power supply of the wireless power supply transmitter module and the wireless power supply receiver module, and this embodiment does not limit this.

[0109] Optionally, after determining that there are foreign objects in the operating environment of the wireless power supply transmitter module and the wireless power supply receiver module, the method further includes: controlling the clothing processing equipment to stop operating.

[0110] For example, taking the determination that foreign objects exist in the operating environment of the wireless power transmission module and the wireless power receiving module during the stage when the user is using the clothing processing equipment as an example, after determining that foreign objects exist in the operating environment of the wireless power transmission module and the wireless power receiving module, it means that the wireless power receiving module cannot supply power to the first electrical appliance normally. The clothing processing equipment can be controlled to stop operating in order to avoid the first electrical appliance in the clothing processing equipment from being unable to start and use, causing abnormal clothing processing problems.

[0111] For example, the clothing processing equipment is a dryer, and the first electrical appliance is a conductivity detection device. If the wireless power supply receiving module cannot supply power to the conductivity detection device normally, the conductivity detection device cannot determine whether the clothes are dry during the drying process, and then controls the clothing processing equipment to stop to avoid over-drying the clothes.

[0112] Optionally, after determining that there are foreign objects in the operating environment of the wireless power supply transmitting module and the wireless power supply receiving module, the method further includes: adjusting the runtime of the clothing processing program of the clothing processing device to a preset duration.

[0113] For example, the clothing processing device is a dryer, and the first electrical appliance is a conductivity detection device. Since the wireless power supply receiver module cannot properly supply power to the conductivity detection device, the conductivity detection device cannot determine whether the clothes are dry during the drying process. Therefore, the running time of the clothing processing program can be adjusted to a preset time, such as adjusting the drying time to a preset time. The preset time can be set based on relevant drying experience. Thus, the clothing processing device can continue drying the clothes while avoiding the problem of the conductivity detection device failing to detect conductivity and thus failing to determine whether the clothes are dry, causing the drying program to run continuously and resulting in over-drying of the clothes.

[0114] Optionally, the wireless power supply receiving module is used to supply power to the first electrical component of the clothing processing equipment; after determining that there are foreign objects in the operating environment of the wireless power supply transmitting module and the wireless power supply receiving module, the method further includes: controlling the second electrical component in the clothing processing equipment to start; wherein, the second electrical component has the same function as the first electrical component, and the second electrical component is wired powered.

[0115] For example, the clothing processing equipment is a dryer, the first electrical appliance is a conductivity detection device, and the second electrical appliance is also a conductivity detection device. Both the first and second electrical appliances can detect the conductivity inside the clothing processing drum and determine whether the clothes are dry based on the conductivity. The second electrical appliance can be installed on the front support of the clothing processing equipment and is wired powered. When there are foreign objects in the operating environment of the wireless power supply transmitter and receiver modules, the first electrical appliance cannot detect the conductivity, but the power supply to the second electrical appliance is not affected. Therefore, the second electrical appliance can be powered on, and its conductivity can be detected to determine whether the clothes are dry, thereby ensuring the normal operation of the drying process.

[0116] It should be noted that the control method after determining that there are foreign objects in the working environment of the wireless power supply transmitting module and the wireless power supply receiving module can be executed by the first control board in the wireless power supply receiving module, or the first control board can send instructions to the main control board of the clothing processing device and execute them. This disclosure embodiment does not limit this method.

[0117] Optionally, after determining that there are foreign objects in the operating environment of the wireless power supply transmitter module and the wireless power supply receiver module, the method further includes: generating a prompt message indicating that there are foreign objects in the operating environment of the wireless power supply transmitter module and the wireless power supply receiver module.

[0118] Specifically, if foreign objects are found in the operating environment of the wireless power supply transmitter and receiver modules, abnormal received signal parameter information can be stored and a prompt message can be generated to alert maintenance personnel to promptly repair the wireless power supply transmitter and receiver modules. For example, the prompt message can be at least one of sound, light, or display prompt messages; this embodiment of the disclosure is not limited in this regard.

[0125] S306. It is determined that there is a foreign object in the transmission channel between the wireless power supply receiving module and the wireless power supply transmitting module.

[0126] S307, the wireless power supply transmitter module and the wireless power supply receiver module are working normally.

[0128] The control method for the clothing processing equipment provided in this embodiment determines the presence of foreign objects in the operating environment of the wireless power supply transmitter and receiver modules by determining the received signal parameter information and, based on the received signal parameter information meeting preset fault conditions. By detecting the operating status of the wireless power supply transmitter and receiver modules, abnormal wireless power supply transmitter and receiver modules can be detected in a timely manner, thereby enabling timely repair. This avoids the problem that foreign objects in the operating environment of the wireless power supply transmitter and receiver modules prevent them from supplying power to the first electrical appliance normally, thus affecting the normal use of the clothing processing equipment. This improves the user experience and enhances the reliability of the clothing processing equipment.

[0129] This disclosure also provides a control device for a garment processing device. Figure 4 is a schematic diagram of the structure of a control device for a garment processing device provided in this disclosure. As shown in Figure 4, the control device for the garment processing device includes: a parameter information determination module 401, used to determine the received signal parameter information based on the received signal from the wireless power supply receiving module; and an anomaly detection module 402, used to determine that there is a foreign object in the working environment of the wireless power supply transmitting module and the wireless power supply receiving module according to the received signal parameter information meeting preset fault conditions.

[0130] The apparatus and methods provided in the above embodiments of this disclosure are based on the same inventive concept and have the same beneficial effects, and will not be described in detail here.

[0131] In related technologies, wireless power transmission in garment processing equipment utilizes electromagnetic induction between a receiving coil and a transmitting coil for both energy and data transfer. However, the transmission efficiency can be low due to environmental factors or installation defects, failing to meet the demands of the appliance and rendering the garment processing equipment unusable. Therefore, a method to detect and improve transmission efficiency is urgently needed.

[0132] To address the aforementioned problems, this disclosure provides a control method for a garment processing device. Figure 5 is a flowchart illustrating the control method for a garment processing device provided in this disclosure. This method can be executed by a control device for the garment processing device provided in this disclosure. The control device can be installed in a wireless power supply transmission module, and the control device can be implemented using software and / or hardware. As shown in Figure 5, the method includes the following steps:

[0133] S1101. Obtain feedback information sent by the wireless power supply receiving module.

[0134] Figure 2 is a schematic diagram of the physical structure of a garment processing device provided in an embodiment of this disclosure. Exemplarily, as shown in Figure 2, the garment processing device may include a wireless power supply receiving module 3 and a wireless power supply transmitting module 2. The wireless power supply transmitting module 2 is disposed on the casing of the garment processing device, for example, on the back panel of the housing 5. The wireless power supply receiving module 3 is disposed on the garment processing drum 1 of the garment processing device, and is used to supply power to the electrical appliance 4 (the first electrical appliance mentioned above) on the garment processing device. This embodiment of the disclosure does not limit the number or type of the electrical appliance 4 (the first electrical appliance mentioned above).

[0135] The wireless power transmission module 2 and the wireless power receiving module 3 transmit electrical energy without contact, meaning that power transmission can be achieved without wire connection between them. For example, the aforementioned clothing processing device also includes a support shaft 6, which connects the housing 5 and the clothing processing drum 1.

[0136] The wireless power supply transmitting module 2 includes a transmitting coil and a first control board. The wireless power supply receiving module 3 may include, for example, a receiving coil and a second control board. Preferably, both the transmitting and receiving coils are arranged around the support shaft 6. Energy can be transferred between the transmitting and receiving coils via a magnetic field. For example, the first control board converts 220V AC to 12V AC and supplies power to the transmitting coil. After the transmitting coil is energized, it generates a changing magnetic field. The receiving coil can generate current through electromagnetic induction, thereby realizing energy transfer. This allows the wireless power supply receiving module 3 and the wireless power supply transmitting module 2 to still supply power to the appliance 4 (the first appliance mentioned above) even when the clothes handling drum 1 is rotating.

[0137] The second control board in the wireless power supply receiver module 3 modulates the current generated by the receiving coil to obtain parameters such as amplitude, phase, frequency, or quality factor (Q value) corresponding to the current information, which will not be listed here.

[0138] Furthermore, the wireless power supply receiving module 3 and the wireless power supply transmitting module 2 can also achieve bidirectional data transmission via carrier communication. The transmitted signal of the wireless power supply transmitting module 2 is modulated onto a high-frequency carrier signal and sent to the wireless power supply receiving module 3. The wireless power supply receiving module 3 demodulates the high-frequency carrier signal to restore the original information, thereby obtaining the transmitted signal parameter information. The received signal of the wireless power supply receiving module 3 is modulated onto a high-frequency carrier signal and sent to the wireless power supply transmitting module 2. The wireless power supply transmitting module 2 demodulates the high-frequency carrier signal to restore the original information, thereby obtaining the received signal parameter information.

[0139] Therefore, the wireless power transmission module can receive feedback information sent by the wireless power receiving module via wireless communication.

[0140] S1102. Based on the feedback information, the operating parameters of the wireless power supply transmitter module are adjusted to meet the triggering conditions for improving transmission efficiency.

[0141] For example, because the receiving coil and transmitting coil are not aligned during initial installation but are offset, the contact area between the wireless power supply receiving module and the wireless power supply transmitting module is reduced, leading to decreased transmission efficiency. Additionally, since the transmitting coil is fixed to the housing of the garment processing device, while the receiving coil is mounted on the garment processing drum and rotates with it, any eccentricity in the drum during rotation can also prevent the receiving and transmitting coils from being perfectly aligned, further reducing transmission efficiency. Furthermore, problems such as the receiving and transmitting coils being too close or too far apart, or severe magnetic leakage, can also significantly reduce transmission efficiency.

[0142] The feedback information indicates that the transmission efficiency improvement trigger condition is met, which means that the transmission efficiency between the wireless power supply transmitter module and the wireless power supply receiver module is low. The energy received by the wireless power supply receiver module from the wireless power supply transmitter module is limited and cannot supply power to the electrical appliances of the clothing processing equipment normally. Therefore, the working parameters of the wireless power supply transmitter module should be adjusted to improve the transmission efficiency between the wireless power supply transmitter module and the wireless power supply receiver module.

[0143] For example, the input voltage or input current of the wireless power supply transmitter module can be increased to enhance its electromagnetic induction capability, thereby increasing the energy emitted by the wireless power supply transmitter module and thus improving transmission efficiency.

[0144] This embodiment of the disclosure is based on feedback information that meets the trigger condition for improving transmission efficiency, indicating that the transmission efficiency between the wireless power supply transmitting module and the wireless power supply receiving module is low. By adjusting the operating parameters of the wireless power supply transmitting module, the transmission efficiency between the wireless power supply transmitting module and the wireless power supply receiving module is improved, so that the wireless power supply receiving module can supply power to the electrical appliance normally, ensuring the normal operation of the clothing processing equipment.

[0145] Optionally, the feedback information includes transmission efficiency; the transmission efficiency is determined by the wireless power receiving module based on the received signal parameters of the wireless power receiving module and the transmitted signal parameters of the wireless power transmitting module.

[0146] Based on feedback information that meets the triggering conditions for improving transmission efficiency, the operating parameters of the wireless power supply transmitter module are adjusted, including: adjusting the operating parameters of the wireless power supply transmitter module when the transmission efficiency is less than or equal to a preset efficiency threshold.

[0147] For example, the wireless power supply transmitting module can send the transmitting signal parameters to the wireless power supply receiving module via carrier communication. The wireless power supply receiving module obtains the input power of the transmitting coil from the transmitting signal parameters, obtains the output power of the receiving coil from the receiving signal parameters, and determines the transmission efficiency between the wireless power supply transmitting module and the wireless power supply receiving module based on the ratio of the output power of the receiving coil to the input power of the transmitting coil.

[0148] The wireless power receiving module sends the transmission efficiency as feedback information to the wireless power transmitting module. The wireless power transmitting module adjusts its operating parameters based on the transmission efficiency being less than or equal to a preset efficiency threshold.

[0149] It should be noted that the preset efficiency threshold can be set according to the actual power supply requirements of the wireless power receiving module and the wireless power transmitting module. For example, the preset efficiency threshold can be the minimum efficiency at which the electrical energy generated by the wireless power receiving module can power the appliance. If the efficiency is less than this, the appliance cannot start. This embodiment does not limit the specific value of the preset efficiency threshold.

[0150] Optionally, the feedback information includes the received signal parameters of the wireless power supply receiver module;

[0151] Based on feedback information that meets the triggering conditions for improving transmission efficiency, the operating parameters of the wireless power supply transmitting module are adjusted, including: determining the transmission efficiency between the wireless power supply receiving module and the wireless power supply transmitting module according to the received signal parameters of the wireless power supply receiving module and the transmitted signal parameters of the wireless power supply transmitting module; and adjusting the operating parameters of the wireless power supply transmitting module if the transmission efficiency is less than or equal to a preset efficiency threshold.

[0152] For example, the wireless power supply receiving module can send received signal parameters to the wireless power supply transmitting module, and the wireless power supply transmitting module can also obtain transmitted signal parameters. The wireless power supply transmitting module obtains the output power of the receiving coil from the received signal parameters and the input power of the transmitting coil from the transmitted signal parameters. Based on the ratio of the output power of the receiving coil to the input power of the transmitting coil, the transmission efficiency between the wireless power supply transmitting module and the wireless power supply receiving module is determined.

[0153] When the transmission efficiency is less than or equal to the preset efficiency threshold, the operating parameters of the wireless power supply transmitter module are adjusted, such as increasing the input voltage or input current of the wireless power supply transmitter module, thereby improving the transmission efficiency.

[0154] Optionally, the feedback information includes adjustment instructions sent by the wireless power receiving module; wherein, the adjustment instructions are generated by the wireless power receiving module based on the received signal parameters of the wireless power receiving module and the transmitted signal parameters of the wireless power transmitting module, determining that the transmission efficiency is less than or equal to a preset efficiency threshold;

[0155] Based on feedback information that meets the triggering conditions for improving transmission efficiency, the operating parameters of the wireless power supply transmitter module are adjusted, including: adjusting the operating parameters of the wireless power supply transmitter module based on the obtained adjustment command.

[0156] For example, the wireless power supply transmitting module can send the transmitting signal parameters to the wireless power supply receiving module, and the wireless power supply receiving module can also obtain the receiving signal parameters. The wireless power supply receiving module obtains the output power of the receiving coil from the receiving signal parameters and the input power of the transmitting coil from the transmitting signal parameters. Based on the ratio of the output power of the receiving coil to the input power of the transmitting coil, the wireless power supply transmitting module determines the transmission efficiency between the wireless power supply transmitting module and the wireless power supply receiving module. When the transmission efficiency is less than or equal to a preset efficiency threshold, the wireless power supply receiving module sends an adjustment command to the wireless power supply transmitting module. Based on the adjustment command, the wireless power supply transmitting module adjusts its operating parameters to improve the transmission efficiency.

[0157] Optionally, adjusting the operating parameters of the wireless power supply transmitter module includes: determining the operating parameter adjustment value corresponding to the transmission efficiency based on the correspondence between the transmission efficiency and the operating parameter adjustment value; and adjusting the operating parameters of the wireless power supply transmitter module according to the operating parameter adjustment value corresponding to the transmission efficiency.

[0158] For example, a pre-stored correspondence between transmission efficiency and operating parameter adjustment values ​​can be established. For instance, a transmission efficiency of A1 corresponds to an increase in input voltage of B1 volts, and a transmission efficiency of A2 corresponds to an increase in input voltage of B2 volts, and so on. Once the transmission efficiency is determined, the corresponding operating parameter adjustment value can be determined by looking up a table. Based on this operating parameter adjustment value, the operating parameters of the wireless power supply transmitter module are adjusted. For example, if the operating parameter adjustment value corresponding to the transmission efficiency is B1 volts, then the input voltage value of the wireless power supply transmitter module is increased by B1 volts.

[0159] Optionally, the operating parameters of the wireless power supply transmitter module can be adjusted, including adjusting the operating parameters of the wireless power supply transmitter module according to preset adjustment values.

[0160] For example, when adjusting the input voltage of the wireless power supply transmitter module to improve transmission efficiency, the voltage adjustment value can be preset to, for example, 0.2 volts. When it is necessary to adjust the operating parameters of the wireless power supply transmitter module, the input voltage of the wireless power supply transmitter module is increased by 0.2 volts.

[0161] It should be noted that the preset adjustment value can be set according to the actual power supply requirements of the wireless power supply receiving module and the wireless power supply transmitting module, and this embodiment does not limit this.

[0162] Optionally, after adjusting the operating parameters of the wireless power supply transmitting module based on the feedback information meeting the transmission efficiency improvement trigger condition, the process further includes: returning to execute the operation of obtaining the feedback information sent by the wireless power supply receiving module; adjusting the operating parameters of the wireless power supply transmitting module based on the feedback information meeting the transmission efficiency improvement trigger condition; wherein the number of times the operating parameters of the wireless power supply transmitting module are adjusted is greater than or equal to 2.

[0163] For example, the operating parameters of the wireless power supply transmitter module can be adjusted multiple times. Taking two adjustments of the operating parameters of the wireless power supply transmitter module as an example, after the first adjustment of the operating parameters of the wireless power supply transmitter module, the wireless power supply transmitter module returns feedback information sent by the wireless power supply receiver module again. If the feedback information meets the trigger condition for improving transmission efficiency, it means that the first adjustment of the operating parameters of the wireless power supply transmitter module did not improve the transmission efficiency to the normal transmission efficiency range, and the transmission efficiency is still too low. Then, the operating parameters of the wireless power supply transmitter module are adjusted again to improve the transmission efficiency.

[0164] It should be noted that the number of times the operating parameters of the wireless power supply transmitting module are adjusted can be set according to the actual adjustment of the transmission efficiency between the wireless power supply receiving module and the wireless power supply transmitting module, and this embodiment does not limit this.

[0165] Optionally, the control method further includes: generating a prompt message based on the number of times the operating parameters of the wireless power supply transmission module are adjusted reaches a threshold and the feedback information meets the triggering condition for improving transmission efficiency.

[0166] For example, a preset threshold can be set. When the number of times the operating parameters of the wireless power supply transmitter module are adjusted exceeds the threshold, it indicates that adjusting the operating parameters of the wireless power supply transmitter module alone cannot improve the transmission efficiency to the normal range. At this time, a prompt message is generated to inform the user that the wireless power supply receiver module and the wireless power supply transmitter module have malfunctioned, or to prompt the relevant maintenance personnel to repair the wireless power supply receiver module and the wireless power supply transmitter module in a timely manner. For example, the inspection personnel can disassemble the device to check whether the distance between the receiving coil and the transmitting coil is too far or too close, or whether the eccentric distance of the clothing processing tube is too large during installation, and repair the wireless power supply receiver module and the wireless power supply transmitter module according to the corresponding fault causes.

[0167] Optionally, the control method further includes: generating a prompt message based on the fact that the difference in transmission efficiency between the wireless power supply receiving module and the wireless power supply transmitting module after two consecutive adjustments of the operating parameters of the wireless power supply transmitting module is less than a preset difference, and the feedback information meets the trigger condition for improving transmission efficiency.

[0168] For example, after the wireless power supply transmitter module obtains the first adjustment of its operating parameters, the transmission efficiency between the wireless power supply receiver module and the wireless power supply transmitter module is, for example, C1. After the wireless power supply transmitter module obtains the second adjustment of its operating parameters, the transmission efficiency between the wireless power supply receiver module and the wireless power supply transmitter module is, for example, C2. The difference between C2 and C1 is less than a preset difference, and the transmission efficiency C2 between the wireless power supply receiver module and the wireless power supply transmitter module is still less than or equal to the preset efficiency threshold. This indicates that adjusting the operating parameters of the wireless power supply transmitter module has little effect on improving the transmission efficiency and cannot improve the transmission efficiency to the normal range. At this time, a prompt message is generated to remind the user that the wireless power supply receiver module and the wireless power supply transmitter module have malfunctioned, or to remind the relevant maintenance personnel to repair the wireless power supply receiver module and the wireless power supply transmitter module in a timely manner.

[0169] For example, the prompt information may be at least one of sound prompt information or display prompt information, and this disclosure embodiment does not limit it.

[0174] S1304. Adjust the operating parameters of the wireless power supply transmitter module.

[0175] S1305. Obtain the transmission efficiency between the wireless power supply transmitter module and the wireless power supply receiver module again.
