Abstract
Description
Technical Field
[0001] This disclosure relates to the field of household electrical technology, and more particularly to an electrical system for a garment processing device, and the garment processing device itself. Background Technology
[0002] Clothing handling equipment, such as dryers, needs to handle multiple loads during daily use, including high-voltage loads (such as motors, heating elements, and water valves) and low-voltage loads (such as sensors and control chips). These loads are connected to the power supply and control circuits via their respective wires.
[0003] However, in traditional garment processing equipment, high-voltage and low-voltage wires are often bundled together, relying solely on the wire bundle itself for insulation and protection. During machine operation, electromagnetic or signal interference can occur between different wires, affecting the normal operation of the equipment. In particular, when low-voltage wires such as communication lines are close to high-voltage wires such as motor wires, the incidence of communication failures increases significantly, and fault location becomes difficult, causing considerable inconvenience to equipment maintenance and use. Utility Model Content
[0004] In view of the above problems, this disclosure is made in order to provide an electrical system for a garment processing device that overcomes or at least partially solves the above problems, and a garment processing device in which strong and weak current loads and wires are arranged on different substrates to achieve separation of strong and weak currents, effectively reducing mutual interference between strong and weak current wires, facilitating fault location and maintenance, and improving the reliability and safety of the device.

[0020] The technical solutions provided in this disclosure have at least the following technical effects or advantages:
[0021] This disclosure provides an electrical system and garment processing equipment for use in garment processing. By placing the high-voltage load and high-voltage wires on a first substrate and the low-voltage load and low-voltage wires on a second substrate, the high-voltage and low-voltage modules are physically separated. The first and second substrates are arranged at intervals, maintaining a certain distance between the high-voltage and low-voltage wires. This effectively reduces electromagnetic interference and signal interference between the high-voltage and low-voltage components, improving the operational stability and reliability of the equipment. Furthermore, the separation of high-voltage and low-voltage components allows for faster problem localization in case of malfunction, reducing maintenance difficulty and costs, enhancing equipment reliability and safety, and ultimately improving user experience and satisfaction.

In order to better understand the technical means of this disclosure and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this disclosure more apparent and understandable, specific embodiments of this disclosure are described below. Attached Figure Description
[0023] Various other advantages and benefits will become apparent to those skilled in the art upon reading the following detailed description of preferred embodiments. The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this disclosure. Furthermore, the same reference numerals denote the same parts throughout the drawings. In the drawings:
[0024] Figure 1 This is a schematic diagram of the structure of a garment processing device provided in an embodiment of this disclosure;
[0025] Figure 2 This is a schematic diagram of the layout of an electrical system for a garment processing device provided in an embodiment of this disclosure;
[0026] Figure 3 This is a schematic diagram of the layout of an electrical system for a garment processing device provided in an embodiment of this disclosure. Detailed Implementation
[0027] To better understand the above technical solutions, the following will describe the above technical solutions in detail with reference to the accompanying drawings and specific implementation methods. It should be understood that the embodiments of this disclosure and the specific features in the embodiments are detailed descriptions of the technical solutions of this disclosure, rather than limitations on the technical solutions of this disclosure. In the absence of conflict, the embodiments of this disclosure and the technical features in the embodiments can be combined with each other.
[0028] To better understand this disclosure, the following is a brief description of the structure of the garment processing equipment involved in this disclosure:
[0029] Figure 1 This is a schematic diagram of the structure of a garment processing device provided in an embodiment of this disclosure, as shown below. Figure 1 As shown, the garment processing device 100 includes a housing M, a control circuit board S1, and a display panel S2. The control circuit board S1 is mounted on one side wall of the housing M, and the display panel S2 is embedded in the other side wall of the housing M. The display panel S2 is used for user interaction with the dryer, and the control circuit board S1 receives commands input by the user through the display panel S2 and controls various functions and operating states of the garment processing device 100. Currently, both the high-voltage and low-voltage loads of the garment processing device 100 are arranged on the control circuit board S1, and the high-voltage and low-voltage wires are often bundled together without proper separation. Interference occurs between the high-voltage and low-voltage wires, causing varying degrees of impact on the machine's operation, and the root cause cannot be located.
[0030] High-voltage loads typically refer to equipment or components that require high voltage (e.g., 220V) and high current power. Low-voltage loads, on the other hand, refer to equipment or components that require low voltage and low current power, and are commonly used in fields such as communication and data transmission. High-voltage wires are used to connect high-voltage loads to the power source. These wires typically have high current carrying capacity and voltage ratings to ensure safe and stable power supply to the high-voltage loads. Low-voltage wires, however, are used to connect low-voltage loads in a dryer to the power source or control circuitry. Compared to high-voltage wires, low-voltage wires have lower current carrying capacity and voltage ratings. They are typically used to transmit control signals or low-level signals, such as analog or digital signals output from sensors.
[0031] To prevent interference between circuits in clothing processing equipment (such as dryers), which can lead to excessive electromagnetic emissions and oversensitivity to external interference, the wiring of the machine must be prioritized during the design phase. Interference-resistant wiring not only saves development time but also reduces development costs. In electromagnetic interference design, cables are always the primary channel for radiation or the introduction of interference due to their length. Cables are not only "transmitting antennas" but also excellent receiving antennas. Proper wiring can effectively suppress internal circuit noise and filter out interference signals introduced from the outside via the wires.
[0032] To address this issue, various methods have been employed in related technologies. One common approach is to add ferrite cores to both high-voltage and low-voltage wires. Ferrite cores, in particular, can absorb and dissipate electromagnetic waves, thereby reducing electromagnetic interference (EMI). However, this method also presents several challenges. For instance, the core may saturate due to excessive current flowing through the wire, significantly reducing its EMI suppression capability. Furthermore, adding cores increases the cost and size of electronic devices, and the placement and installation method require precise control to avoid excessive signal attenuation or interference with other parts of the device. Another method involves dividing the circuit board into high-voltage and low-voltage zones to separate high-voltage and low-voltage wires and reduce EMI between them. However, this method also faces several challenges. First, the circuit board layout and design need to be more complex to ensure effective isolation between the high-voltage and low-voltage zones. Second, with the miniaturization and integration of electronic devices, space on circuit boards is becoming increasingly limited, making the division of high-voltage and low-voltage zones more difficult. Moreover, even with zone division, high-voltage wires can still interfere with low-voltage wires through electromagnetic radiation or capacitive coupling.
[0033] Therefore, in order to better solve the above-mentioned technical problems, this disclosure provides an electrical system for a garment processing device. Figure 2This is a schematic diagram of the layout of an electrical system for a garment processing device provided in an embodiment of this disclosure, such as... Figure 2 As shown, the electrical system includes a first substrate 10, a second substrate 20, a high-voltage module 30, and a low-voltage module 40, with the second substrate 20 spaced apart from the first substrate 10. The high-voltage module 30 includes a high-voltage load and high-voltage wires (not shown in the figure) located on the first substrate 10, and the low-voltage module 40 includes a low-voltage load and low-voltage wires (not shown in the figure) located on the second substrate 20.
[0034] By placing the high-voltage and low-voltage modules on separate substrates, complete physical isolation between the modules is achieved. This isolation method is more convenient and effective than simply dividing the circuit into areas on the same board, significantly reducing electromagnetic interference between the high and low voltage modules. Furthermore, the separate design of the high-voltage and low-voltage modules facilitates rapid fault location and maintenance, improving equipment reliability and safety.
[0035] Secondly, in related technologies, since the strong and weak current modules are on the same circuit board, they may interfere with each other through capacitive coupling or electromagnetic radiation. Separating them onto different substrates can significantly reduce this coupling effect, improving the stability and reliability of the electrical system. Furthermore, placing the strong and weak current modules on separate substrates allows designers greater flexibility in planning the circuit board layout. This helps optimize the circuit structure and improve the performance and reliability of the circuit board. Moreover, using separate first and second substrates to support the strong and weak current modules facilitates modular design. This design approach not only facilitates production and testing but also helps reduce maintenance costs and improve maintenance efficiency.
[0036] Furthermore, since high-voltage loads typically generate significant heat, while low-voltage loads are temperature-sensitive, separating high-voltage and low-voltage loads onto different substrates facilitates more effective thermal management. Designers can tailor heat dissipation solutions to the different characteristics of high-voltage and low-voltage loads, thereby improving the heat dissipation performance of the electrical system and ultimately enhancing the stability and reliability of the equipment.
[0037] Optionally, high-voltage and low-voltage conductors are arranged alternately, and the minimum distance between high-voltage and low-voltage conductors meets the requirements for electrical clearance and creepage distance.
[0038] Clearance, in particular, is the shortest spatial distance measured between two conductive components or between a conductive component and the protective interface of an equipment. It is the shortest distance that allows insulation to be achieved through air while ensuring stable and safe electrical performance. Creepage distance refers to the shortest path along the insulating surface between two conductive components or between a conductive component and the protective interface of an equipment. Both clearance and creepage distance can be determined by consulting relevant national or industry standards based on parameters such as the conductor's operating voltage, insulation material, and insulation class, or they can be determined through electrical calculations and experimental tests.
[0039] In some implementations, the minimum distance between high-voltage and low-voltage conductors is greater than 1 cm to ensure that the spacing between the high-voltage and low-voltage conductors meets the requirements for electrical clearance and creepage distance.
[0040] Among them, the minimum distance between high-voltage and low-voltage conductors is the minimum straight-line distance between the conductors.
[0041] In some implementations, such as Figure 2 As shown, the garment processing device includes a housing M, and a first substrate 10 and a second substrate 20 are disposed at different parts of the housing M to achieve an interval arrangement of the first substrate 10 and the second substrate 20.
[0042] In some implementations, combined Figure 1 and Figure 2 The first substrate 10 is the control circuit board S1 of the garment processing equipment 100, and the second substrate 20 is the display panel S2 of the garment processing equipment. Using the existing display panel S2 of the garment processing equipment to house the low-voltage loads and wiring avoids the need for additional installation space inside or outside the garment processing equipment, thus saving overall space. Simultaneously, placing the low-voltage loads near the display panel reduces the length of the low-voltage wires. This helps reduce wiring complexity and cost. Furthermore, display panels are typically designed with heat dissipation holes or structures, which aid in heat dissipation. Placing the low-voltage loads near the display panel utilizes these heat dissipation structures to lower the operating temperature of the low-voltage loads, improving stability and reliability.
[0043] In some implementations, such as Figure 2 As shown, the first substrate 10 and the second substrate 20 are located on different sidewalls of the housing M. By placing the two substrates on different sidewalls of the housing, the distance between the two substrates can be increased, allowing the high-voltage and low-voltage wires to be routed separately from the two sidewalls. This further increases the distance between the high-voltage and low-voltage wires, better reducing electromagnetic interference between them and improving the stability and safety of the equipment. Simultaneously, it can also reduce the impact of heat generated by the high-voltage load during operation on the low-voltage load. In other embodiments, the first substrate 10 and the second substrate 20 may also be located on the upper or lower surface of the housing, etc., and this is not limited.
[0044] Figure 3 This is a schematic diagram of the layout of another electrical system for a garment processing device provided in this disclosure, as shown in the embodiment. Figure 3 As shown, in some embodiments, the first substrate 10 and the second substrate 20 are located on the same side wall of the housing. By placing the two substrates on the same side wall of the housing, space can be utilized more effectively, the wiring complexity of strong and weak current wires can be reduced, and it is easier for maintenance personnel to observe the strong and weak current loads on each substrate, which helps to simplify the maintenance process.
[0045] It should be noted that, Figure 2 and Figure 3 The illustration only shows a portion of the housing of the garment processing equipment, and the housing and various substrates shown are merely examples. The actual housing M and the positions and shapes of the various plates can also be in other forms, and this disclosure does not limit them.
[0046] In some implementations, the low-voltage and high-voltage conductors are shielded or twisted-pair cables. Shielded and twisted-pair cables have better anti-interference performance, reducing the interference of external electromagnetic fields on signals and helping to further reduce mutual interference between high-voltage and low-voltage conductors.
[0047] In some implementations, the low-voltage conductors are fitted with insulating protective sleeves. On the one hand, this protects the low-voltage conductors from physical damage, reducing the probability of electrical faults; on the other hand, it can shield and attenuate some electromagnetic waves to a certain extent, reducing electromagnetic interference that could cause communication failures in the low-voltage conductors.
[0048] In some embodiments, the electrical system further includes a transformer module (not shown) located on the first substrate 10 and connected to the high-voltage module 30 and the low-voltage module 40, for converting the first voltage of the high-voltage module 30 into a second voltage suitable for the low-voltage module 40.
[0049] For example, the transformer module can be a transformer, with one end connected to the high-voltage module 30 and the other end connected to the low-voltage module 40, so as to convert the high voltage of the high-voltage module 30 into a low voltage suitable for the low-voltage module 40, and protect the low-voltage load from damage.
[0050] In some implementations, the high-voltage load includes at least a motor and a heating element, while the low-voltage load includes at least a control circuit and a sensor. In other implementations, the high-voltage load may also include other devices or components in the garment handling equipment that use high voltage and high current power supply, such as a fan motor for generating hot air. The low-voltage load may also include other devices or components in the garment handling equipment that use low voltage and low current power supply, such as a display screen for showing the dryer's status and operating instructions, and various status indicator lights.
