[0027] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] It should be noted that when an element is referred to as "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to or indirectly connected to the other element. Unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] First, some terms used in the embodiments of this application will be explained to facilitate understanding by those skilled in the art.

[0032] Cyclic Redundancy Check (CRC) is a data transmission error detection function. It generates a cyclic redundancy check code at the data sending end, appends it to the data, and sends it to the data receiving end. The receiving end recalculates the check code based on the received data and compares it with the received check code to determine whether an error occurred during data transmission.

[0033] Negative temperature coefficient thermistors (NTCs) are used in the electronics field because their resistance decreases as temperature increases. Therefore, they are commonly used in temperature measurement, temperature control, and overheat protection.

[0034] The Inter-Integrated Serial Bus (I2C) is a synchronous serial bus with a multi-master-slave architecture. This bus requires only a serial data line (SDA) and a serial clock line (SCL) to enable communication between multiple devices.

[0035] The Serial Peripheral Interface Bus (SPI) is a high-speed, full-duplex, synchronous communication bus that typically consists of four lines: Master Output / Slave Input (MOSI), Master Input / Slave Output (MISO), Serial Clock (SCK), and Chip Select (SS).

[0036] The Controller Area Network Bus (CAN bus) uses differential signal transmission and communicates data through two lines (CAN_H and CAN_L). It supports multi-master communication mode, and each node on the bus can send and receive data equally.

[0037] The above is a brief introduction to the terms used in the embodiments of this application, and will not be repeated below.

[0038] As described in the background section, clothes dryers and other garment processing equipment have become essential tools in modern life, greatly enhancing convenience. Early garment processing equipment had relatively simple communication architectures. In traditional dual-frequency conversion systems, communication primarily revolved around basic motor drives and simple control command transmissions; the communication interfaces and schemes could meet the relatively limited functional requirements of the time.

[0039] However, with the continuous development of the times, people's lifestyles and product requirements are also constantly changing. On the one hand, as global attention to energy conservation and emission reduction increases, users expect equipment to reduce energy consumption while operating efficiently. On the other hand, the garment processing equipment industry is also constantly pursuing technological breakthroughs and innovations, actively exploring more advanced functions and more efficient operating modes. Against this backdrop, triple-frequency conversion and even more variable-frequency technologies are gradually being applied to garment processing equipment.

[0040] Taking clothes dryers as an example, tri-frequency or multi-frequency conversion technology can significantly improve the performance of dryers by independently and precisely controlling the frequency of multiple key components, achieving a more efficient drying process that saves both time and energy. However, multi-frequency conversion systems make the internal communication of dryers extremely complex, requiring frequent and accurate data exchange and collaborative work between different frequency conversion components. At the same time, the integration of various sensors, intelligent control modules, and other load devices into the dryer places higher demands on the number and performance of hardware communication interfaces.

[0041] Traditional dryer communication solutions and interfaces are gradually revealing their shortcomings in the face of these new changes: they cannot meet the stringent requirements for data transmission speed, stability, and accuracy in complex communication scenarios, nor can they support the connection of more load devices. This not only limits further improvements in dryer performance but may also lead to problems such as equipment instability and increased failure rates, failing to meet users' demands for high-quality, intelligent clothing processing equipment.

[0042] Reference Figures 1 to 4 To address the aforementioned problems, this utility model provides an example of a communication architecture, which is configured in a garment processing device, such as... Figure 1 The diagram shows a structural schematic of a communication architecture, which includes:

[0043] The display control board 101 has a communication interface connected to a serial bus.

[0044] The load control board 102 establishes a communication connection with the display control board 101 via a serial bus.

[0045] High-speed optocoupler 103: The first end of high-speed optocoupler 103 establishes a communication connection with display control board 101 via a serial bus; the second end of high-speed optocoupler 103 is connected in parallel to multiple frequency converter control boards. Figure 1 The first frequency converter control board 104, the second frequency converter control board 105, and the third frequency converter control board 106 are schematically drawn, but are not limited to these.

[0046] The high-speed optocoupler 103 is used to electrically isolate the display control board 101 from multiple frequency converter control boards (such as the first frequency converter control board 104, the second frequency converter control board 105, and the third frequency converter control board 106). Each frequency converter control board establishes a communication connection with the display control board 101 through the high-speed optocoupler 103.

[0047] In some embodiments, the garment handling equipment may be a washing machine, a dryer, or a washer-dryer combo.

[0048] In this example of the present invention, the display control board serves as the core of the communication architecture, and its communication interface is connected to a serial bus. In some embodiments, the display control board typically integrates a microcontroller (MCU) with serial communication capabilities, which is then connected to the serial bus via this communication interface to enable communication with other components.

[0049] In some embodiments of this invention, the serial bus can be one of an I2C bus, an SPI bus, or a CAN bus. The load control board establishes a communication connection with the display control board via the serial bus. The corresponding interface on the load control board interfaces with the serial bus, receives commands from the display control board, and feeds back its own status information.

[0050] The first end of the high-speed optocoupler is connected to the display control board via a serial bus, and the second end of the high-speed optocoupler is connected in parallel to multiple frequency converter control boards. By transmitting control signals between the display control board and the multiple frequency converter control boards, the high-speed optocoupler not only electrically isolates the display control board and the multiple frequency converter control boards, preventing interference from high-voltage circuits to low-voltage control circuits, but also ensures rapid transmission of control signals between the control board and the frequency converter control boards.

[0051] In some embodiments of this utility model, the frequency converter control board is used to control the frequency converter components (such as the main circulating fan, compressor, drum motor, etc.) of the dryer. Each frequency converter control board establishes a communication connection with the display control board through a high-speed optocoupler, and is used to receive broadcast instructions or control signals from the display control board, adjust the operating status of the corresponding connected frequency converter components, and feed back the working status of the frequency converter components to the display control board.

[0052] Taking a clothes dryer as an example, by introducing three-frequency or multi-frequency conversion technology, independent and precise frequency conversion control of multiple key components in the dryer can significantly improve its performance and achieve a more efficient drying process, saving both time and reducing energy consumption. However, introducing three-frequency or multi-frequency conversion technology also complicates the communication of the dryer. In one embodiment, a master-slave communication architecture provided by this invention is adopted. Each slave device is assigned a unique broadcast address. The display control board, as the master, sends commands to at least one broadcast address via a serial bus. Each slave device receives and executes the corresponding command according to its own broadcast address, and simultaneously feeds back its working status. This enables the display control board to broadcast communication and read back the status of various slave devices, ensuring orderly communication and solving the problem of increased communication complexity caused by introducing three-frequency or multi-frequency conversion technology into the dryer.

[0053] The communication architecture provided by this utility model introduces a serial bus and uses only one communication interface of the display control board to expand the communication interface with multiple slave devices (load control boards, multiple frequency conversion control boards, etc.). This solves the problem of limited communication interfaces in existing clothing processing equipment. It not only saves serial port resources, but also meets the needs of more load devices to be connected to clothing processing equipment now and in the future. It has strong scalability, can adapt to complex communication scenarios, and meet more hardware communication interface requirements.

[0054] In one embodiment, such as Figure 2 As shown, the communication architecture also includes:

[0055] The signal transceiver 201 is connected to an external device (not shown in the figure) and the display control board 101.

[0056] The signal transceiver is used to transmit data between an external device and a display control board at a first communication rate. The signal transceiver is at least one of a Wi-Fi communication module, a 5G communication module, a Bluetooth communication module, a distance-based wireless connection (NFC) module, a ZigBee module, and a USB direct connection communication module.

[0057] In some embodiments of this invention, the external device may include, but is not limited to, a mobile app, a cloud server, etc. In the communication architecture, the signal transceiver acts as a bridge connecting the display control board and the external device, enabling data interaction between the display control board of the garment processing equipment and the external device.

[0058] For example, taking a clothes dryer as a garment processing device, the operating status and fault information of the dryer can be uploaded to a mobile APP or cloud server. It is also possible to receive control commands from the mobile APP or cloud server to achieve remote control functions.

[0059] In some embodiments of the present invention, the signal transceiver is used to transmit data between an external device and a display control board at a first communication rate.

[0060] In some embodiments, the first communication rate is set according to the data transmission requirements between the external device and the display control board, for example, it may be a baud rate of 115200. Based on the first communication rate, the data transmission speed is reasonably controlled to avoid communication failures or system instability caused by data transmission being too fast or too slow, thus ensuring reliable communication between the garment processing equipment and the external device.

[0061] Different external devices and application scenarios have different requirements for data transmission rates. For example, if you are pushing simple running status information to a mobile app, you don't need a very high rate, such as 9600 baud rate. However, if you are interacting with a large amount of data with a mobile app or cloud server, such as software upgrade data, you need a relatively high rate, such as 115200 baud rate.

[0062] By using a signal transceiver device to establish a connection between external devices and the display control board, the communication range of the clothing processing equipment's communication architecture is expanded. This allows the clothing processing equipment to no longer be limited to communication between internal control boards, but to interact with the wider world outside, meeting users' needs for remote monitoring and operation of the dryer, and improving the dryer's intelligence level and user experience.

[0063] Furthermore, during data transmission between external devices and the display control board, by reasonably setting the first communication rate of the signal transceiver, it is possible to ensure stable and efficient data transmission between the external devices and the display control board, avoiding data loss or transmission errors.

[0064] In one embodiment, it is still as follows Figure 2 As shown, the communication architecture also includes:

[0065] The load device 202 is connected to the load control board 102. The load control board 202 is used to transmit data with the display control board at a second communication rate, wherein the second communication rate is less than the first communication rate.

[0066] In some embodiments of this invention, the load device can be an electrical component such as a temperature sensor (e.g., a negative temperature coefficient thermistor, NTC, etc.) or a lighting fixture (LED lighting, etc.). In one embodiment, electrical wiring can be used to directly connect the load device to the corresponding interface on the load control board.

[0067] It should be understood that, taking a clothes dryer as an example, the load device is typically a component of the dryer that does not require high data transmission speeds. The load device receives operating instructions and reports its own status through the load control board. Specifically, the load control board and the display control board are connected via a serial bus, using serial communication to transmit data and achieve information exchange.

[0068] In this example of the utility model, the microcontroller in the display control board has a serial communication function. By configuring the baud rate of the serial communication through software, the communication rate between the load control board and the display control board is set to a second communication rate, such as 9600 baud rate or 4800 baud rate (less than the first communication rate), so as to achieve stable communication between the display control board and the load control board.

[0069] The load control board acts as a bridge between the load devices and the display control board. It receives control commands from the display control board and converts them into control signals suitable for the load devices, thereby controlling their operating status. For example, it controls the NTC for temperature detection or controls the on / off state of LED lighting. Simultaneously, the load control board can collect the operating status information of the load devices and feed it back to the display control board at a second communication rate, enabling the display control board to provide real-time feedback to the user on the load devices' operational status.

[0070] In contrast to the higher primary communication rate between the display control board and external devices, a lower secondary communication rate is set because the load devices have relatively lower requirements for data transmission speed. This allows more communication resources to be allocated to external devices or other critical modules with higher speed requirements, while still meeting internal communication needs. It also avoids allocating excessive communication bandwidth to load devices with lower data transmission speed requirements, thus saving system resources. This differentiated communication rate setting better adapts to the characteristics of different devices and communication scenarios, thereby improving the stability and reliability of the communication architecture.

[0071] In one embodiment, such as Figure 3 As shown, the communication architecture also includes:

[0072] The main circulating fan 301 is connected to the first frequency converter control board 104 among multiple frequency converter control boards via electrical wiring. The main circulating fan 301 is used to adjust at least one of the air circulation volume and circulation speed inside the clothing processing equipment.

[0073] In some embodiments, the main circulating fan is a core component of the internal air circulation system of a garment processing device (such as a dryer). It can regulate the volume and speed of air circulation within the device to improve drying efficiency and quality. For example, taking a dryer as an example, in the initial stage of drying, the main circulating fan increases the volume and speed of air circulation to accelerate the discharge of humid air and the entry of dry air, allowing the garments to lose moisture more quickly. In the later stage of drying, the main circulating fan appropriately reduces the air circulation speed to avoid over-drying and damaging the garments.

[0074] In some embodiments, the electrical wiring between the main circulating fan and the first frequency converter control board can not only carry the power supply for the main circulating fan, but also transmit control signals for controlling the operating status of the main circulating fan. The first frequency converter control board, acting as an intermediate control hub, converts control commands from the display control board into appropriate voltage and frequency signals to drive the main circulating fan to operate as required.

[0075] The first frequency converter control board establishes a communication connection with the display control board via a high-speed optocoupler. The display control board, acting as the communication host, sends control commands for the main circulating fan to the first frequency converter control board via a serial bus and the high-speed optocoupler. Upon receiving the control commands, the first frequency converter control board adjusts the power parameters output to the main circulating fan according to the command content, thereby achieving precise control of the main circulating fan. Simultaneously, the first frequency converter control board can also collect the operating status information of the main circulating fan (such as actual speed and current) and feed it back to the display control board through the same communication path.

[0076] In this example, the circulating main fan communicates with the display control board via a first frequency converter control board. The display control board can precisely control the operating status of the circulating main fan based on factors such as different operating stages of the garment processing equipment, the type and quantity of garments, etc. Simultaneously, the operating status feedback information of the circulating main fan can help the display control board understand and provide real-time feedback on the air circulation within the garment processing equipment, thereby enabling coordinated control of other components (such as compressors and heating elements), making the garment processing process more intelligent and efficient.

[0077] By precisely adjusting the airflow and circulation speed, the main circulating fan can make the temperature and humidity distribution inside the garment processing equipment more uniform, avoiding local overheating or overhumidification, which helps to improve drying efficiency, shorten drying time, and also improve drying quality, reduce wrinkles and deformation of clothes, and make clothes drier and softer.

[0078] In this example, variable frequency control technology combined with a communication architecture is used, allowing the main circulating fan to adjust its operating power according to actual needs. For example, when high air volume and high wind speed are not required, the fan's operating speed can be reduced, thereby reducing energy consumption. Compared to traditional fixed-frequency fans, this intelligent control method can significantly improve energy utilization efficiency and reduce operating costs.

[0079] In one embodiment, it is still as follows Figure 3 As shown, the communication architecture also includes:

[0080] The compressor 302 is connected to the second frequency converter control board 105 of a plurality of frequency converter control boards via electrical wiring. The compressor 302 is used to adjust at least one of the temperature and humidity during the drying operation of the garment processing equipment.

[0081] In some embodiments, the compressor is a key drying component of the garment processing equipment, primarily responsible for regulating temperature and humidity during the drying process. During drying, the compressor controls air temperature and humidity through a cooling or heating cycle. For example, when the humidity inside the garment processing equipment is high, the compressor can activate a cooling cycle, causing the humid air to condense on the evaporator, thereby removing moisture and reducing humidity. When it is necessary to increase the temperature inside the garment processing equipment, the compressor can compress the refrigerant, causing it to release heat in the condenser to heat the air.

[0082] In some embodiments of this invention, the compressor is connected to a second variable frequency control board among multiple variable frequency control boards via an electrical circuit. Specifically, this electrical circuit provides the compressor with the power required for operation and transmits control signals from the second variable frequency control board.

[0083] In one example, the second variable frequency control board acts as a control hub, receiving control commands from the display control board and converting them into appropriate electrical signals to drive the compressor. For example, the second variable frequency control board can adjust the output voltage and frequency to change the compressor's speed and power.

[0084] In another example, the second frequency converter control board establishes a communication connection with the display control board via a high-speed optocoupler. The display control board, acting as the host in the communication architecture, sends control commands to the second frequency converter control board via a serial bus. In some embodiments, these control commands include control requirements for the compressor's operating status, such as starting, stopping, and adjusting the speed. Simultaneously, the second frequency converter control board monitors the compressor's operating parameters (such as current, pressure, and temperature) in real time and feeds these parameters back to the display control board via the high-speed optocoupler and serial bus, achieving bidirectional data transmission.

[0085] In one embodiment, the compressor can work in conjunction with other components (such as the main circulating fan, heating elements, etc.) to achieve an efficient drying process. The display control board precisely controls the compressor via a second frequency converter control board based on the condition of the clothing and the preset drying program. Simultaneously, the compressor's operating status also affects the operation of other components; for example, the compressor's cooling or heating effect affects the workload of the main circulating fan. The display control board comprehensively regulates these interrelationships to ensure the stable operation of the entire drying system.

[0086] Through this utility model example, the communication architecture enables the compressor's operating status to be fed back to the display control board in real time, allowing the display control board to promptly detect and handle abnormal situations. For example, when the compressor experiences overload, overheating, or other faults, the display control board can immediately take measures, such as stopping the compressor or adjusting the operating status of other components, to protect the equipment and extend its service life.

[0087] Furthermore, the variable frequency compressor can adjust its operating power according to actual needs, avoiding the energy waste of traditional compressors operating at a fixed power. By precisely regulating temperature and humidity, the compressor can dry clothes in a suitable environment, avoiding damage caused by excessive temperature or humidity, such as shrinkage, deformation, and fading. This helps improve drying quality and keeps clothes in good appearance and performance.

[0088] As one example, it remains the same Figure 3 As shown, the communication architecture also includes:

[0089] The drum motor 303 is connected to the third frequency converter control board 106 among multiple frequency converter control boards via electrical wiring. The drum motor 303 is used to drive the rotation of the drum inside the garment processing equipment, and to adjust at least one of the rotation speed, rotation direction and rotation time of the drum.

[0090] In some embodiments, within the communication architecture, the primary function of the drum motor is to drive the rotation of the drum inside the garment handling equipment. During the drying process, the rotation of the drum causes the garments to tumble continuously, ensuring full contact with hot air and improving drying efficiency and uniformity. By controlling the rotation of the drum, it is ensured that the garments receive comprehensive processing within the equipment, preventing localized sparse or over-dried areas.

[0091] The drum motor can also adjust the drum's rotation speed, direction, and time. Different types and materials of clothing have different requirements for the drum's operating parameters. For example, lighter clothing requires a lower rotation speed and shorter rotation time to prevent tangling and damage; while heavier clothing requires a higher rotation speed and longer rotation time to ensure drying effectiveness. Through a communication architecture, the display control board can precisely control the drum motor according to the characteristics of the clothing and preset drying programs, thereby achieving flexible adjustment of the drum's operating parameters.

[0092] In some embodiments, the drum motor is connected to a third frequency converter control board via an electrical circuit. This electrical circuit is responsible for transmitting power to drive the drum motor and also for transmitting control signals. As a key component connecting the drum motor and the display control board, the third frequency converter control board can receive control commands from the display control board and convert these commands into electrical signals suitable for the drum motor, thereby controlling various operating parameters of the drum motor.

[0093] The third frequency converter control board establishes a communication link with the display control board via a high-speed optocoupler. The display control board, acting as the host of the communication architecture, sends control commands to the third frequency converter control board via a serial bus. In some embodiments, these control commands include setting requirements for parameters such as the rotational speed, direction, and time of the drum motor. Simultaneously, the third frequency converter control board monitors the drum motor's operating status in real time, such as actual speed and current, and feeds this information back to the display control board via the high-speed optocoupler and serial bus, enabling bidirectional data transmission and interaction.

[0094] In another example, the drum motor works in conjunction with other components (such as the main circulating fan and compressor) to complete the drying task. For instance, during the drying process, the rotational speed and direction of the drum motor affect the airflow within the equipment, thus influencing the workload of the main circulating fan and the cooling or heating effect of the compressor. The display control board, through comprehensive control of each component, enables the various load devices to cooperate with each other, achieving an efficient and stable drying process.

[0095] The communication architecture provided by this invention allows the drum motor to be flexibly adjusted according to different types of clothing and drying needs, enhancing the adaptability of the clothing processing equipment. Users can select a suitable drying program based on actual conditions, and the clothing processing equipment can also automatically adjust the operating parameters of the drum motor to meet diverse drying requirements.

[0096] Furthermore, by precisely controlling the drum's rotation speed, direction, and time, the drum motor can dry clothes under suitable conditions, reducing tangling and damage, and improving the uniformity and quality of drying. Clothes can be better stretched and tumbled inside the drum, thus making full contact with hot air and achieving more efficient moisture evaporation and drying.

[0097] As one embodiment, the display control board integrates a Cyclic Redundancy Check (CRC) circuit. The CRC circuit performs cyclic redundancy checks on the communication data between the display control board and the load control board, as well as the communication data between the display control board and the frequency converter control board. When the number of times the failed communication data is discarded reaches a predetermined number (such as 3 times, 5 times, etc., which can be set according to communication requirements and is not specifically limited), a communication failure message is reported to the display control board.

[0098] In one implementation, the CRC circuit can be software-based CRC verification using a dedicated CRC calculation chip, or it can be a CRC calculation module implemented within the microcontroller (MCU) of the display control board using hardware logic circuitry. For example, some high-performance MCUs have built-in CRC software calculation functions, which can easily perform CRC verification on communication data by configuring the corresponding registers and interfaces.

[0099] In one possible implementation, when the display control board communicates with the load control board and the frequency converter control board, the data sender (e.g., the load control board or the frequency converter control board) calculates the CRC checksum of the data to be sent according to a pre-determined CRC algorithm (which can use existing CRC calculation formulas and is not limited to this one), selects the corresponding number of bits (e.g., CRC-16), and packages it together with the data before sending it. Upon receiving the data packet, the CRC circuit of the data receiver (e.g., the display control board) recalculates the CRC of the received data to obtain the CRC checksum. If the calculated CRC checksum matches the received CRC checksum, it indicates that no error occurred during data transmission, meaning the data was correctly received; if the calculated CRC checksum does not match the received CRC checksum, it indicates that a data transmission error occurred, and the receiver will discard the received data.

[0100] In this example, the CRC circuit can also count the number of times failed verification data is discarded. When the number of times failed verification communication data is discarded reaches a predetermined number, it indicates that data errors are frequently occurring during communication, and a communication failure may exist. At this time, the CRC circuit reports a communication failure message to the display control board, notifying the display control board to take corresponding measures, such as stopping related operations and displaying a fault message.

[0101] In the communication architecture of clothing handling equipment such as dryers, data transmission may be subject to various interferences, such as electromagnetic interference and line noise, leading to data errors. Therefore, in the communication architecture provided in this utility model example, a CRC circuit can promptly detect these errors, preventing erroneous data from being processed and ensuring the accuracy of communication data between the display control board, load control board, and frequency converter control board.

[0102] Furthermore, when data errors occur, the CRC circuit can promptly discard erroneous data, preventing the spread and accumulation of errors and reducing equipment failures and abnormal operation caused by data errors. Simultaneously, through the fault reporting mechanism, the display control board can promptly understand the communication status and take corresponding corrective measures, further improving the reliability of the communication architecture.

[0103] Furthermore, the number of failed verifications and the reported communication fault messages recorded by the CRC circuit provide important information for fault diagnosis. When a communication failure occurs, maintenance personnel can determine whether the data error is caused by a problem with the communication line, the equipment interface, or other reasons based on the communication fault messages reported by the CRC circuit, thereby locating and resolving the fault more quickly and improving equipment maintenance efficiency.

[0104] In one embodiment, the load control board and the frequency converter control board each have a unique broadcast address assigned by the display control board. The display control board is also used to perform communication broadcasting and status readback based on the broadcast address.

[0105] In a garment processing device, during the device initialization phase, the display control board can assign unique broadcast addresses to the load control board and each frequency converter control board. In some embodiments, the assignment process can be based on a preset algorithm or the device's hardware identifier (such as device number, serial number, etc.). After the assignment is completed, the display control board stores these broadcast address information in its internal memory and simultaneously sends the corresponding broadcast address information to each control board, ensuring that each control board clearly knows its unique identifier.

[0106] When the display control board needs to send control commands to one or more control boards, it includes the broadcast address of the target control board in the communication data. The display control board broadcasts the control commands via the serial bus. All load control boards and frequency converter control boards will receive this broadcast message, but only the control board whose broadcast address matches the target address in the message will process the control command; other control boards will ignore the broadcast message.

[0107] When the display control board needs to know the operating status of a certain control board, it sends a status query command containing the broadcast address of that control board. Upon receiving the command, the corresponding control board encapsulates its own operating status information (such as current operating mode, parameter settings, fault status, etc.) according to a prescribed format and returns it to the display control board via the serial bus. The display control board identifies which control board returned the information based on the broadcast address, thus achieving status readback.

[0108] In the communication architecture, by assigning unique broadcast addresses to the load control board and frequency converter control board respectively, the display control board can accurately communicate with each load control board and frequency converter control board. In a communication architecture containing multiple slave devices, without unique address identifiers, the display control board cannot distinguish between different control boards, nor can it send control commands or obtain status information to specific control boards. Through the unique broadcast addresses pre-assigned to the load control board and frequency converter control board, the display control board can precisely interact with each control board, achieving independent control and management of each component.

[0109] In some embodiments, when the display control board acts as a host to operate multiple control boards in a unified manner (such as simultaneously starting or stopping multiple control boards), broadcast communication based on a pre-assigned unique broadcast address can greatly improve communication efficiency and reduce communication time and resource consumption. Simultaneously, the status readback function allows the display control board to promptly understand the working status of each control board, enabling adjustments and optimizations based on actual conditions.

[0110] Furthermore, a unique broadcast address facilitates the expansion of the communication architecture of garment processing equipment. In another embodiment, when a new load control board or frequency converter control board needs to be added to the communication architecture, the display control board only needs to assign a new unique broadcast address to the new load control board or frequency converter control board to seamlessly integrate it into the existing communication architecture. Communication between the new load control board or frequency converter control board and the display control board will not affect the normal operation of the original communication architecture.

[0111] As one embodiment, the display control board is used to communicate and broadcast status to the load control board and the frequency converter control board at a second communication rate.

[0112] In some embodiments, the display control board sends communication broadcast messages to the load control board and the frequency converter control board via a serial bus at a second communication rate (e.g., 9600 baud or 4800 baud). When sending the broadcast message, the display control board encapsulates the instructions or data in a specific format and adds the broadcast address of the target control board. All load control boards and frequency converter control boards connected to the serial bus receive these broadcast messages, but only the control board whose broadcast address matches will process the information.

[0113] When the display control board needs to obtain the status of the load control board or frequency converter control board, it sends a status query command at the second communication rate. Upon receiving the query command, the corresponding control board encapsulates its own status information (such as operating mode, running parameters, fault status, etc.) according to a prescribed format and sends it back to the display control board via the serial bus at the second communication rate. The display control board parses and processes the received information to understand the operating status of each control board.

[0114] In this example, the load devices (such as electrical components, motors, etc.) connected to the load control board and frequency converter control board have relatively low requirements for data transmission speed, and the data volume is generally small. Using a second communication rate for communication broadcasting and status readback can meet the communication needs of these control boards and their controlled devices, avoid resource waste caused by using excessively high communication rates, and also reduce communication complexity and cost.

[0115] Furthermore, selecting an appropriate secondary communication rate helps reduce interference and errors during communication. At lower communication rates, signal transmission quality is more easily guaranteed, and data transmission stability is higher. This is crucial for ensuring that the load control board and frequency converter control board can accurately receive instructions from the display control board, and that the display control board can reliably obtain status information from each control board, thereby guaranteeing the stable operation of the entire dryer system.

[0116] In another embodiment, the second end of the high-speed optocoupler transmits data to multiple frequency converter control boards at a second communication rate.

[0117] In some embodiments of this invention, the second end of the high-speed optocoupler is connected to multiple frequency converter control boards via electrical circuitry, establishing a physical channel for data transmission. Simultaneously, communication-related hardware is configured on each frequency converter control board and in the circuitry that works with the high-speed optocoupler, including setting an appropriate clock frequency and adjusting communication interface parameters to ensure consistent communication speed with the display control board and the first end of the high-speed optocoupler. For example, in the microcontroller of the frequency converter control board, the baud rate of the serial communication module is set to a second communication rate.

[0118] When the display control board sends data to the frequency converter control board, it first transmits the data at the second communication rate to the first end of the high-speed optocoupler. The high-speed optocoupler converts the electrical signal into an optical signal for isolated transmission, and then converts the optical signal back into an electrical signal at the second end, transmitting it to the corresponding frequency converter control board at the second communication rate. After receiving the data, the frequency converter control board parses and processes the data according to the preset communication protocol. Conversely, when the frequency converter control board needs to send data back to the display control board, it also transmits the data back at the same rate and through the isolation transmission mechanism of the high-speed optocoupler.

[0119] High-speed optocouplers provide electrical isolation between the display control board and multiple frequency converter control boards. When transmitting data at the second communication rate, the high-speed optocouplers effectively prevent high-voltage circuits from interfering with low-voltage control circuits, avoiding data transmission errors or equipment damage caused by electrical interference, thus ensuring the safety and stability of the entire communication architecture. For example, during the operation of a dryer, the frequency converter control board controls high-power equipment such as the compressor and drum motor, which operate at high voltages. The isolation provided by the high-speed optocouplers ensures that the display control board is unaffected by electrical fluctuations on the high-voltage side.

[0120] For load devices (such as circulating fans, compressors, and drum motors) controlled by multiple frequency converter control boards, the data transmission speed requirements are not extremely high. Using a second communication rate for data transmission can meet the communication needs of the frequency converter control boards and their controlled load devices. Furthermore, a unified second communication rate ensures consistency and order in data transmission between the high-speed optocoupler and multiple frequency converter control boards, avoiding problems such as data corruption, loss, or misinterpretation caused by inconsistent communication rates.

[0121] Reference Figure 4 The schematic diagram of the garment processing device shown illustrates that, to address the aforementioned problems, this embodiment of the invention also provides a garment processing device, which includes: a main body 400, and a communication architecture (not specifically shown, but can be referenced) disposed within the main body. Figures 1 to 4 ).

[0122] In some embodiments of this invention, the clothing processing equipment can be a washing machine, a dryer, or a washer-dryer combo.

[0123] In some embodiments, the main body of the garment processing device can be made of materials such as metal or plastic, possessing a certain degree of strength and protective performance. During the design of the main body, suitable space and installation locations are reserved to accommodate the various components of the communication architecture. For example... Figure 4 As shown, the display control panel 101 can be installed on the front or top of the door of the garment processing equipment for easy operation and viewing by the user.

[0124] In some embodiments, load control boards, frequency converter control boards, etc., are installed in suitable positions inside the main body according to the internal layout of the garment processing equipment and the convenience of wiring connections, and are firmly fixed inside the main body by fixing devices (such as screws, clips, etc.). Electrical isolation components such as high-speed optocouplers can also be reasonably arranged in appropriate positions inside the main body according to electrical characteristics and heat dissipation requirements.

[0125] The various components in the communication architecture (display control board, load control board, high-speed optocoupler, frequency converter control board, etc.) are electrically connected and configured according to design requirements. A complete communication architecture is formed by connecting these components via serial buses and electrical lines, ensuring accurate data transmission and control command interaction between them.

[0126] It should be understood that clothing processing equipment is exposed to various environmental factors during use, such as humid air and clothing fibers. In this example, the main body of the clothing processing equipment can provide physical protection for the internal communication architecture, internal power supply components, washing drum, or drying drum, preventing external dust, moisture, mechanical impacts, and other factors from damaging the electronic components in the communication architecture. This ensures the stability and reliability of the communication architecture and extends the service life of the clothing processing equipment.

[0127] Through this utility model example, the main body encapsulates the communication architecture and other internal components together to form a unified device appearance. The operation interface and display devices (such as displays, indicator lights, etc.) on the display control board are located outside the main body, facilitating user operation and monitoring of the device's operating status. Simultaneously, the well-designed main body (which can be understood as a mounting shell) also makes maintenance of the garment processing equipment more convenient.

[0128] Furthermore, the well-designed main body not only protects the internal communication architecture and enhances the device's aesthetics, but also allows users to easily operate the equipment, view its operating status and fault information, thus improving usability and user experience.

[0129] Furthermore, in this example, the communication architecture is the core component for achieving intelligent control and efficient operation of the garment processing equipment. The communication architecture can monitor and control the operating status of various components of the equipment (such as the main circulating fan, compressor, drum motor, etc.) in real time, and perform precise control and adjustment according to different garment processing needs, achieving precise control and coordinated operation of each component. For example, through communication between the display control board and other control boards, parameters such as drying temperature, humidity, and drum speed can be adjusted, thereby ensuring high-quality garment processing. For example, through intelligent control of components such as the main circulating fan, compressor, and drum motor, drying efficiency can be improved, energy consumption reduced, and garment damage minimized, providing users with better garment processing results.
