[0036] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0037] It should be noted that like reference numerals denote like items in the following drawings, and therefore, once an item is defined in one drawing, it will not be further defined or explained in the subsequent drawings.

[0038] The electric clothes drying machine wireless signal receiving system 100 takes into account the compactness and functionality of the overall structure. The combination of the controller 10 and the metal light board 20 provides a practical and efficient solution to ensure the normal operation of the electric clothes drying machine and the convenience of user operation. The specific technical solution will be elaborated in detail below: Figure 1 and Figure 2 As shown, a wireless signal receiving system 100 for an electric clothes drying machine includes a controller 10 and a metal light board 20 mounted on a bottom plate 101 of a clothes drying machine 102 ; the metal light board 20 is located below the controller 10 .

[0039] The controller 10 is responsible for receiving and processing signals from remote controls or other wireless devices. These signals may include controlling the clothes dryer's on / off function, lighting control, timer settings, and other possible intelligent functions. The controller 10 is mounted on the base plate 101 of the main clothes dryer 102 in a relatively concealed location to reduce the risk of accidental damage and facilitate integration with the other components of the clothes dryer.

[0040] The technical solution for the electric clothes dryer's wireless signal reception system fully considers wireless signal reception efficiency and anti-interference capabilities. By mounting the controller 10 on the base plate 101 and positioning the metal light panel 20 below it, the metal light panel's potential shielding effect on wireless signals is reduced. Furthermore, the layout of the flexible wire antenna 13 within the controller 10 also helps improve signal reception quality. Its embedded layout and appropriate distance from the metal light panel 20 ensure stable and reliable signal transmission.

[0041] More specifically, the controller 10 includes a plastic housing 11, a control board 12, and a flexible wire antenna 13. One end of the flexible wire antenna 13 is connected to the control board 12, which is fixed within the plastic housing 11. The control board 12 is the electronic core of the controller 10 and integrates multiple electronic components 122, including but not limited to a microprocessor, memory, input / output interfaces, power management circuits, and a wireless communication module. These components work together to receive and decode wireless signals and execute corresponding control commands based on the signals, such as starting or stopping the electric clothes dryer's motor. The control board 12 is fixed within the plastic housing 11, ensuring stability and durability during the operation of the electric clothes dryer.

[0042] The plastic housing 11 serves as the exterior protective structure for the controller 10, protecting it from environmental factors such as dust, moisture, and other external factors that could affect the proper functioning of the controller's internal components. The plastic housing 11 comprises a top wall 111, side walls 112, and a bottom wall 113, which together provide a robust enclosure for the controller's internal components.

[0043] The flexible wire antenna 13 is the wireless signal receiving component of the controller 10. It is designed to be flexible to adapt to different installation environments and locations while maintaining efficient signal reception. One end of the flexible wire antenna 13 is connected to the control board 12. This end preferably includes a connector to ensure a stable and reliable electrical connection with the control board. The other end of the antenna extends outside the plastic housing 11 to ensure optimal wireless signal reception.

[0044] More specifically, bottom wall 113 is provided with a through-hole 114, and a groove 115 extending outward from through-hole 114 is also provided on its surface. Bottom wall 113 plays a crucial role in the sophisticated technical implementation of the wireless signal receiving system 100 for electric clothes drying machines. This bottom wall not only provides a stable base support for the controller 10, but also, through the design of through-hole 114 and groove 115, cleverly integrates functionality and aesthetics.

[0045] Via hole 114 is a precise opening in bottom wall 113 that ensures the flexible wire antenna 13 can pass smoothly through the bottom wall, connecting the controller's internal precision electronic components with the external signal world. This via is designed with precision and antenna protection in mind, ensuring that the antenna is not damaged by friction during passage and preventing potential interference from the external environment.

[0046] Groove 115, extending outward from via 114, is a carefully designed channel on the surface of bottom wall 113. It not only houses the flexible wire antenna 13 but also provides protection for it. The depth and width of groove 115 have been precisely calculated and designed to ensure the antenna fits perfectly within the groove while maintaining a certain spacing to avoid short circuits or signal attenuation caused by direct contact with bottom wall 113.

[0047] During installation, the flexible wire antenna 13 passes through the through hole 114 and is cleverly embedded in the groove 115. This embedded design not only provides physical protection for the antenna, reducing the risk of damage due to external forces, but also helps maintain the shape and structure of the antenna, ensuring it maintains good signal reception capabilities in various usage environments.

[0048] It should also be noted that the distance L between the flexible wire antenna 13 and the metal light panel 20 is greater than 20 mm. This ingenious spatial layout effectively prevents the metal light panel 20 from potentially shielding or interfering with the wireless signal. Due to its conductivity, metal materials may absorb or reflect wireless signals, thereby affecting signal transmission efficiency. By maintaining a certain distance, the system ensures that the wireless signal can be received by the controller 10 with minimal interference, thereby maintaining the wireless control performance of the electric clothes dryer.

[0049] Overall, the synergistic technical approach of vias 114 and grooves 115 on bottom wall 113, along with the embedded layout of flexible wire antenna 13, constitutes a key technical innovation highlight of wireless signal receiving system 100 for electric clothes drying machines. This technical solution not only demonstrates thoughtful consideration of product functionality but also meticulous attention to user experience, ensuring that the entire system not only ensures efficient and stable signal reception but also possesses excellent durability and aesthetics.

[0050] Preferably, the flexible wire antenna 13 comprises a metal conductor and an insulating layer. The metal conductor is the core of the antenna, responsible for transmitting the received wireless signal. To ensure efficient signal transmission, the metal conductor is typically made of highly conductive materials, such as copper or silver, which provide extremely low signal loss and highly efficient transmission.

[0051] The insulation layer wraps around the metal conductor to prevent current leakage and provide mechanical protection. The choice of insulation material must take into account flexibility and environmental resistance to ensure the antenna remains intact when bent or stretched, while also being resistant to environmental influences such as humidity and temperature fluctuations. Common materials used for the insulation layer include polyimide (PI), polyethylene terephthalate (PET), and polyethylene naphthalate (PEN), which have excellent dielectric properties and mechanical strength.

[0052] like Figure 4 and Figure 6 As shown, the extended groove 115 is provided with a plurality of narrowed latches v, which can position the flexible wire antenna 13. These latches v are very critical, as they can accurately position the flexible wire antenna 13 and ensure that the antenna maintains the correct position and angle within the plastic box 11. This technical approach helps improve the antenna's signal reception efficiency and can, to a certain extent, reduce signal loss caused by antenna position deviation. The narrow design of the latches v also provides additional stability, allowing the antenna to remain in place even when the electric clothes dryer vibrates or is affected by external forces.

[0053] The extended groove 115 has a bent section s on the bottom wall 113 to avoid signal interference from the electronic components 122 on the control board 12. This structure is designed to cleverly avoid potential signal interference from the electronic components 122 on the control board 12. This technical solution demonstrates the system inventors' deep understanding and high regard for electromagnetic compatibility (EMC).

[0054] The design of the bent section s ensures that the flexible wire antenna 13 maintains a certain distance from the electronic components 122 in terms of spatial layout, thereby reducing electromagnetic interference between them. This distance not only helps improve the reception quality of wireless signals but is also a key factor in ensuring the stable operation of the entire system. In modern electronic devices, especially wireless communication devices, electromagnetic compatibility is a crucial consideration, directly related to the performance and reliability of the device.

[0055] In addition, the existence of the bending section s can also optimize the signal transmission path to ensure that the wireless signal can remain clear and stable in a complex electromagnetic environment.

[0056] In the field of smart clothes drying technology, these technical details and innovative solutions are key to enhancing user experience and product performance. For example, some smart clothes drying machines integrate multiple sensors and wireless communication modules to enable environmental awareness and remote control. These advanced functional requirements require inventors to make more precise planning and creative contributions in terms of electromagnetic compatibility and signal integrity—efforts that are exemplified by the above technical solutions.

[0057] The control board 12 includes a PCB 121 and multiple electronic components 122 arranged on it. PCB 121 serves as the physical foundation of the control board, providing a mounting platform and electrical connections for the electronic components 122. Preferably, these components 122 include, but are not limited to, a microprocessor, memory, input / output interfaces, power management circuitry, and a wireless communication module, which work together to achieve intelligent control of the electric clothes dryer.

[0058] The layout of the electrical components 122 should follow the modular principle, dividing the circuit into functional modules. At the same time, special attention should be paid to the location of heat-generating components and interference-prone components to ensure that they do not adversely affect other components.
