Description

Technical Field

[0001] This invention relates to the field of wall panel technology, and more specifically, to a waterproof self-heating wall panel device. Background Technology

[0002] Currently, conventional self-heating wall panels mostly use a rigid fixing method between the wall panel and the installation frame. Under heating conditions, the wall panel expands due to heat, but because it is rigidly constrained on all sides, huge thermal stress is generated inside. This stress, acting repeatedly over a long period of time, can easily cause the wall panel to deform and crack at the joints, thereby compromising the wall's airtightness and causing water seepage and leakage problems. At the same time, when the wall panel is heated, the moisture in the air inside the cavity is easily condensed into condensate when it cools down (especially on the side closer to the low outdoor temperature). Condensate can not only erode the wall panel structure and reduce its thermal insulation performance, but may also seep into the area where the heating electrical components are located, causing short circuits and insulation failure, posing serious safety hazards. Summary of the Invention

[0003] To overcome the above-mentioned technical problems, the present invention proposes a waterproof self-heating wall panel device.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0007] A wall panel unit includes an inner wall panel connected to a wall panel mounting groove on one side of a mounting frame. The inner wall panel facing the mounting frame is provided with a sliding connector adapted to the corresponding wall panel mounting groove.

A flow-driving component connected to a condenser is provided between the inner wall panel and the outer wall panel.

[0008] The clamping unit is located between the wall panel units on both sides of the frame unit and is used to clamp the wall panel units on both sides laterally.

[0009] The heating unit is located on the end face of the inner wall panel facing away from the outer wall panel.

The partition plate is located in the center of the independent chamber. The lower support frame has several through holes on the side near the outer wall panel. The top of the partition plate has several backflow grooves. The bottom of the inner wall panel has several exhaust grooves communicating with the independent chamber.

[0012] As a further aspect of the present invention: the condensing component includes a condensing cavity formed within the mounting frame, the condensing cavity being located on the side of the mounting frame away from the wall panel unit, and the bottom of the condensing cavity having a plurality of drain grooves communicating with the outside; the condensing cavity having a plurality of airflow channels corresponding one-to-one with the exhaust grooves on the side facing the inner wall panel, and the lower end of the inner wall panel having a guide component connecting the corresponding exhaust grooves and the airflow channels.

[0013] As a further aspect of the present invention: a plurality of condensing fins are spaced apart inside the condensing cavity, and a condensing plate connected to each condensing fin is provided on the side end face of the mounting bracket away from the wall panel unit.

[0014] As a further aspect of the present invention: the drainage component includes an elastic telescopic hose connected to the exhaust groove, the lower end of the elastic telescopic hose is provided with a sealing ball adapted to the airflow channel, and the elastic telescopic hose and the sealing ball are provided with through holes communicating with the exhaust groove and the airflow channel.

[0015] As a further aspect of the present invention: the clamping unit includes a clamping plate that abuts against the outer wall panels on both sides and a connecting frame that engages with the clamping fixing groove, and the clamping plate is provided with an elastic locking block adapted to the connecting frame on the side facing the connecting frame.

[0016] As a further aspect of the present invention: the inner wall of the clamping and fixing groove is provided with a plurality of slots, and the connecting frame is provided with a flexible expansion strip adapted to the slots.

[0017] As a further aspect of the present invention: the sliding connector includes a first sliding block fixedly connected to the inner wall panel and a second sliding block snapped into the wall panel mounting groove, wherein the first sliding block and the second sliding block are connected only on one side, and a sliding surface is provided at the contact point between the first sliding block and the second sliding block.

[0041] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0042] Please see Figure 1 and Figure 2 The present invention discloses a waterproof self-heating wall panel device, including a frame unit 100, a wall panel unit 200, a clamping unit 300 and a heating unit 400;

[0043] Please see Figure 3 and Figure 4The frame unit 100 includes a mounting bracket 110, on both sides of which wall panel mounting grooves 140 are symmetrically arranged. A clamping and fixing groove 130 is provided in the middle of the mounting bracket 110, and a condenser 120 is disposed within the mounting bracket 110. The wall panel unit 200 includes an inner wall panel 210 connected to one side of the wall panel mounting groove 140 of the mounting bracket 110. The inner wall panel 210 has a sliding groove on the side facing the mounting bracket 110 that is adapted to the corresponding wall panel mounting groove 140. The frame unit 100 includes a connecting member 220; an outer wall panel 230 is provided on the side of the inner wall panel 210 away from the mounting bracket 110; a flow-driving member 250 connected to the condenser 120 is provided between the inner wall panel 210 and the outer wall panel 230; a clamping unit 300 is provided between the wall panel units 200 on both sides of the frame unit 100 for laterally clamping the wall panel units 200 on both sides; and a heating unit 400 is provided on the end face of the inner wall panel 210 facing away from the outer wall panel 230.

[0044] Specifically, the mounting bracket 110 is embedded inside the wall. The side of the mounting bracket 110 with the clamping and fixing groove 130 and the wall panel mounting groove 140 faces the interior, while the side of the mounting bracket 110 away from the clamping and fixing groove 130 and the wall panel mounting groove 140 is exposed to the exterior of the building. The inner wall panels 210 on both sides of the mounting bracket 110 are engaged with the corresponding wall panel mounting grooves 140 through sliding connectors 220, thereby realizing the assembly of the wall panel units 200 on both sides with the frame unit 100. Finally, the clamping unit 300 is horizontally pressed into the clamping and fixing groove 130 from the space between the wall panel units 200 on both sides until the clamping unit 300 abuts against the outer end face of the outer wall panels 230 on both sides, so that the wall panel units 200 on both sides can be clamped and fixed by the clamping unit 300.

[0045] When the wall panel unit 200 is heated by the heating unit 400, the sliding connector 220 can drive the wall panel unit 200 to slide vertically relative to the mounting frame 110 in an adaptive manner, thereby actively absorbing thermal stress and avoiding defects such as deformation, cracking and water seepage of the wall panel caused by shear stress under hot and cold cycles due to the rigid connection between the wall panel and the mounting frame in traditional wall panel devices. In addition, the flow-driving component 250 can drive the moisture between the inner wall panel 210 and the outer wall panel 230 to the condensing component 120 in the mounting frame 110 for condensation and discharge to the outside, maintaining a dry atmosphere inside the wall panel unit 200 and preventing condensation from forming in the cavity inside the wall panel when the temperature changes suddenly, which could lead to electrical short circuits or insulation failure.

[0046] It should be noted that, through the cooperation between the sliding connector 220 and the wall panel mounting groove 140, the wall panel unit 200 can slide vertically adaptively after being heated, actively absorbing and releasing thermal stress, thereby avoiding structural damage caused by temperature deformation and greatly improving the long-term stability and waterproof reliability of the wall panel under continuous heating conditions.

[0047] The linkage system of the drive component 250 and the condenser component 120 can actively guide the moisture between the inner wall panel 210 and the outer wall panel 230 to the condenser component 120 in the mounting bracket 110 for condensation and discharge to the outside of the building, thereby continuously keeping the inside of the wall panel unit 200 dry, eliminating the risk of condensate accumulation, and ensuring the electrical safety and durability of the heating system and the wall structure.

[0048] In one embodiment, please refer to Figure 5 and Figure 6 The wall panel unit 200 further includes a support frame 240 disposed between the inner wall panel 210 and the outer wall panel 230. The support frame 240 is provided in two sets and symmetrically distributed at the upper and lower ends. The two sets of support frames 240 separate the inner wall panel 210 and the outer wall panel 230 to form an independent chamber. The flow-driving component 250 is disposed in the independent chamber.

[0049] Specifically, the inner wall panel 210 and the outer wall panel 230 are distributed in parallel. The inner wall panel 210 and the outer wall panel 230 are fixed by the support frames 240 at both ends. When the heating unit 400 on the back side of the inner wall panel 210 heats the inner wall panel 210, the heat can be quickly conducted to the surrounding wall. The independent chamber can effectively prevent heat loss.

[0050] It is worth noting that a stable support frame is established between the inner wall panel 210 and the outer wall panel 230 through two sets of symmetrically distributed support frames 240, so that the two are kept in parallel distribution, thereby enhancing the overall rigidity and deformation resistance of the wall panel unit 200, and also providing a stable installation environment for its internal drive components 250, thereby ensuring that the wall panel maintains the stability of shape and performance during long-term use and temperature changes.

[0051] The support frame 240 divides the space between the inner wall panel 210 and the outer wall panel 230 into an independent chamber. This chamber forms an air insulation layer. When the heating unit 400 heats the inner wall panel 210, the heat can be concentrated and transferred to the indoor side. The independent chamber can effectively block the heat loss to the outer wall panel 230, greatly reducing heat loss and enhancing the overall thermal insulation performance of the wall, achieving the effects of energy saving and rapid heating.

[0052] The independent chamber is not only used for heat preservation, but also works in conjunction with the flow-driving component 250 to form a closed channel for moisture diversion. Moisture can be directionally transported to the condenser component 120 in the chamber by the flow-driving component 250, avoiding disorderly diffusion or retention inside the wall panel, thereby improving the reliability and efficiency of the dehumidification system and further ensuring long-term dryness inside the wall panel.

[0053] Further, please refer to Figure 6 and Figure 7The flow-driving component 250 includes a fan 251 disposed in the lower support frame 240 and a partition 252 vertically fixed between the upper and lower support frames 240. The partition 252 is located in the center of the independent chamber. The lower support frame 240 has several through holes 241 on the side near the outer wall panel 230. The top of the partition 252 has several return grooves 253. The bottom of the inner wall panel 210 has several exhaust grooves 211 that communicate with the independent chamber.

[0054] Specifically, when the fan 251 is turned on, the airflow is blown upward through each through hole 241 into the independent chamber of the partition 252 near the outer wall panel 230, thereby driving the low-temperature humid air in the independent chamber on that side upward. Then, the airflow flows back through the return groove 253 at the top of the partition 252 to the independent chamber on the side of the partition 252 near the inner wall panel 210, thereby mixing the low-temperature humid air with the high-temperature humid air on that side. Finally, the mixed humid air flows downward and is discharged from each exhaust groove 211 and enters the condenser 120.

[0055] It should be noted that, driven by the fan 251 and combined with the partition 252 separating the flow channels of the independent chamber, a complete forced delivery path is formed. The airflow ejected from the through hole 241 carries moisture, rises along the outer wall panel 230, is guided laterally by the return channel 253, and then descends along the inner wall panel 210, finally being discharged from the exhaust channel 211 to the condenser 120. This effectively overcomes the stagnation of moisture in the cavity, achieves all-round moisture capture and directional removal inside the wall panel, and effectively improves the initiative and reliability of waterproofing.

[0056] By guiding the flow through the reflux channel 253, the low-temperature humid air on the outer wall panel 230 side and the high-temperature humid air on the inner wall panel 210 side affected by the heating unit 400 are mixed in the chamber, which raises the overall temperature and dew point of the humid air. Then, it is introduced into the condenser 120, making the subsequent condensation process easier to occur and requiring a smaller temperature difference.

[0057] The circulating airflow flows closely along the inner surfaces of the inner wall panel 210 and the outer wall panel 230, creating a sweeping effect. This continuously removes moisture accumulated on the inner surface of the wall panel, the support frame 240, and near the potential installation area of ​​the heating unit 400. In particular, it helps to maintain a dry environment around the electrical interface of the heating unit 400, fundamentally preventing the risk of short circuits, corrosion, or insulation aging caused by local condensation, and greatly enhancing electrical safety and system lifespan.

[0058] In yet another embodiment, please refer to Figure 6 and Figure 8The condenser 120 includes a condenser cavity 121 formed in the mounting frame 110. The condenser cavity 121 is located on the side of the mounting frame 110 away from the wall panel unit 200. The bottom of the condenser cavity 121 is provided with a plurality of drain grooves 124 communicating with the outside. The condenser cavity 121 is inclined on the side facing the inner wall panel 210 and is provided with a plurality of airflow channels 122 corresponding to the exhaust grooves 211. The lower end of the inner wall panel 210 is provided with a guide member 260 connecting the corresponding exhaust grooves 211 and the airflow channels 122.

[0059] Specifically, when the wall panel unit 200 is assembled with the mounting bracket 110, each guide component 260 is connected to the corresponding airflow channel 122, so that the airflow in the independent chamber can enter the corresponding airflow channel 122 through each exhaust groove 211 and guide component 260, and finally gather in the condensation chamber 121 for condensation and liquefaction. The liquefied water droplets are discharged from each drain groove 124 to the outside of the building.

[0060] It should be noted that the condensing chamber 121 is set on the side of the mounting frame 110 exposed to the outside of the building, using the outdoor natural environment as a cold source. The warm and humid airflow inside the wall panel delivered by the drive component 250 enters the condensing chamber 121 through the inclined airflow channel 122 and exchanges heat with the low temperature environment outside, thereby naturally condensing and liquefying.

[0061] Moisture inside all wall panel units 200 is collected through multiple drainage components 260 and then centrally treated in a unified condensation chamber 121. The liquid water generated by condensation is directly discharged to the outside of the building through a specially designed drainage trough 124, avoiding the risk of moisture or condensate lingering in the wall structure layer or other parts of the interior, and fundamentally eliminating the hidden dangers of secondary leakage or internal mold growth.

[0062] The airflow channel 122 is designed to be inclined toward the condensation chamber 121. On the one hand, it guides the airflow to flow smoothly into the condensation area. On the other hand, it allows the condensate droplets that may form early on the wall of the airflow channel 122 to slide down to the bottom of the condensation chamber 121 under the action of gravity, preventing blockage of the flow channel. Together with the drain trough 124 at the bottom of the condensation chamber 121, they form a smooth path that relies on gravity for self-drainage, ensuring the long-term maintenance-free reliability of the drainage system.

[0063] The pre-installed airflow guide 260 on the inner wall panel 210 can automatically and accurately align with the corresponding airflow channel 122 when assembled with the mounting bracket 110. This modular plug-in design creates a fully enclosed, invisible airflow channel between the inner cavity of the wall panel and the outer condensation chamber 121. The entire moisture transfer process is completed entirely inside the wall, without occupying indoor or outdoor space, without affecting aesthetics, and also avoiding airflow short-circuiting or backflow of external pollutants.

[0064] Further, please refer to Figure 8 and Figure 9 The condensing chamber 121 is provided with a plurality of condensing fins 123 at intervals, and the mounting bracket 110 is provided with a condensing plate 125 connected to each condensing fin 123 on the side end face away from the wall panel unit 200.

[0065] Specifically, a condenser plate 125 is installed that is directly exposed to the external cold source environment of the building, and multiple sets of condenser fins 123 connected to the condenser plate 125 are installed in the condenser cavity 121. The multiple sets of condenser fins 123 installed at intervals can significantly increase the contact area with the humid and hot air in the condenser cavity 121, so that the heat in the humid and hot gas is quickly conducted to the external cold source environment of the building through the condenser fins 123 and the condenser plate 125, causing the humid and hot gas to condense and liquefy rapidly in the condenser cavity 121.

[0066] It is worth noting that multiple sets of condensing fins 123 are arranged at intervals in the condensing chamber 121, which greatly increases the contact surface area with the hot and humid air in the chamber. Combined with the condensing plate 125 which is directly exposed to the cold environment outside the building, they together form a highly efficient passive heat exchanger with external cooling and internal heating. After the hot and humid gas enters the condensing chamber 121, its heat can be quickly conducted to the external cold source through the huge fin area, thereby achieving rapid and sufficient condensation and liquefaction in the chamber and shortening the dehumidification cycle.

[0067] The condenser plate 125, as the terminal heat dissipation surface that is in direct contact with the outside cold air, maximizes the use of the natural temperature difference between the inside and outside of the building. The condenser fins 123, as an extension of heat conduction, efficiently introduce the cold energy into the depth of the cavity, so that the condensation process is completely driven by the natural cold source and does not require any active cooling components.

[0068] The spaced-apart condenser fins 123 not only increase the heat exchange area but also serve to guide and equalize the flow, allowing the humid and hot gas to diffuse more evenly throughout the condenser chamber 121 and preventing local airflow short-circuiting. At the same time, the gaps between the condenser fins 123 provide a smooth channel for the water droplets formed after condensation to fall, effectively preventing water droplet retention or secondary evaporation, ensuring that the condensate is smoothly collected and discharged into the drain tank 124 at the bottom, thus improving the long-term stability and maintenance-free operation of the system.

[0069] Furthermore, please refer to Figure 8 The drainage component 260 includes an elastic telescopic hose 261 connected to the exhaust groove 211. The lower end of the elastic telescopic hose 261 is provided with a sealing ball 262 adapted to the airflow channel 122. The elastic telescopic hose 261 and the sealing ball 262 are provided with a through hole 263 communicating with the exhaust groove 211 and the airflow channel 122.

[0070] Specifically, when the sliding connector 220 on the inner wall panel 210 is inserted into the wall panel mounting groove 140 of the mounting bracket 110, the elastic telescopic hose 261 undergoes adaptive contraction adjustment, so that the sealing ball 262 is just embedded in the upper opening of the airflow channel 122. Subsequently, the elastic telescopic hose 261 elastically extends, so that the sealing ball 262 is sealed and connected to the opening of the airflow channel 122, thereby achieving a sealed and open airflow channel between the exhaust groove 211 and the airflow channel 122.

[0071] It should be noted that when the wall panel unit 200 undergoes vertical displacement due to thermal expansion and contraction via the sliding connector 220, the elastic telescopic hose 261 can adaptively expand and contract accordingly. At the same time, the sealing ball 262 can still maintain a seal at the opening of the airflow channel 122, ensuring that the airflow channel between the exhaust groove 211 and the airflow channel 122 remains sealed and unobstructed throughout the entire process of dynamic changes in the wall panel, so that the thermal stress release function and the moisture management system can work in parallel without interference.

[0072] During the process of inserting the wall panel unit 200 into the wall panel mounting groove 140, the sealing ball 262 itself has guiding and self-aligning functions. Combined with the contraction adjustment of the elastic telescopic hose 261, it can automatically compensate for minor positional deviations during installation, achieving precise embedding and sealing.

[0073] The sealing ball 262 contacts the arc surface of the upper opening of the airflow channel 122, and a reliable surface seal can be formed under the slight tension of the elastic telescopic hose 261. This avoids the aging or fatigue failure problems that may exist when using adhesives or complex clips, and effectively prevents moisture leakage at the joint between the wall panel and the mounting bracket 110, or external cold air backflow that causes airflow short circuit and reduced condensation efficiency.

[0074] In yet another embodiment, please refer to Figure 10 The fastening unit 300 includes a fastening plate 310 that abuts against the outer wall panels 230 on both sides and a connecting frame 330 that is snapped into the fastening fixing groove 130. The fastening plate 310 is provided with an elastic locking block 320 adapted to the connecting frame 330 on the side facing the connecting frame 330.

[0075] Specifically, first connect the connecting bracket 330 to the clamping and fixing groove 130 in the middle of the mounting bracket 110, then clamp the clamping plate 310 onto the splice of the two outer wall panels 230 until the elastic clip 320 is inserted into the connecting bracket 330, and then use the clamping plate 310 to horizontally clamp and fix the two outer wall panels 230.

[0076] It is worth noting that the clamping plate 310 directly abuts against the two side exterior wall panels 230, and the pressure is transmitted to the pre-embedded mounting bracket 110 through the elastic clip 320 and the connecting bracket 330, forming a closed lateral mechanical frame. This tightly binds the two side wall panel units 200 together, effectively resisting lateral disturbances during use, and ensuring that the splicing of the exterior wall panels 230 is flat and aligned, avoiding misalignment or gaps, and improving the overall aesthetics and airtightness of the wall surface.

[0077] The installation process requires no drilling, welding, or use of wet materials (such as adhesives). Simply insert the connecting bracket 330 into the snap-fit ​​groove 130, and then press the snap-fit ​​plate 310 into the elastic snap-fit ​​block 320 to complete the installation. This simplifies on-site operations, and the elastic snap-fit ​​also facilitates later disassembly, maintenance, or replacement of individual wall panels, achieving reversible installation.

[0078] When the elastic locking block 320 is engaged with the connecting bracket 330, it will generate an appropriate amount of elastic deformation, which not only provides the pre-tightening force required for locking, but also maintains the locking state through its own elasticity without generating excessive constraint stress when the wall panel undergoes slight dimensional changes due to temperature changes. This avoids local deformation or cracking that may be caused by rigid locking. It complements the thermal stress release function of the sliding connector 220 mechanically, and together ensures the long-term stability of the wall panel system under temperature changes.

[0079] Further, please refer to Figure 10 The inner wall of the clamping and fixing groove 130 is provided with a plurality of slots 131, and the connecting frame 330 is provided with a flexible expansion strip 331 adapted to the slots 131;

[0080] Specifically, the flexible expansion strip 331 on the connecting frame 330 is squeezed into the clamping and fixing groove 130. The flexible expansion strip 331 expands outward and is embedded in each slot 131, thereby improving the connection reliability between the connecting frame 330 and the clamping and fixing groove 130. The flexible expansion strip 331 can adaptively contract or expand in the clamping and fixing groove 130 according to the temperature change, thereby compensating for the stress change caused by thermal expansion and contraction, and avoiding rigid deformation between the clamping unit 300 and the frame unit 100 and the wall panel unit 200.

[0081] It should be noted that the flexible expansion strip 331 expands and embeds into the slot 131 after being squeezed into the clamping and fixing groove 130, forming a strong mechanical interlock; at the same time, the elasticity of the flexible material itself allows it to adapt to micro-deformation when the temperature changes, continuously maintaining the clamping force on the groove wall, and improving the fatigue resistance and relaxation resistance of the connection root under long-term hot and cold cycles.

[0082] The vertical sliding absorbs the expansion and contraction between the wall panel and the mounting bracket 110, while the horizontal elastic snap-fit ​​absorbs the deformation between the clamping plate 310 and the connecting bracket 330. The flexible expansion strip 331 here is responsible for absorbing the micro-stress between the connecting bracket 330 and the fixing point of the mounting bracket 110, ensuring that every link in the entire force transmission path from the wall panel surface to the building structure has stress compensation capability, thereby protecting the wall structure from damage by temperature stress in all aspects.

[0083] After expansion, the flexible expansion strip 331 forms a multi-point engagement with multiple slots 131, which greatly increases the frictional resistance and mechanical interlocking force of the connection surface. This enables the connecting frame 330 to reliably resist the vertical pull-out force and horizontal shear force from the wall panel unit 200, firmly anchoring the wall panel to the main structure and improving the structural safety of the entire enclosure system under extreme weather conditions.

[0084] During installation, simply push the connecting bracket 330 with the flexible expansion strip 331 into the groove. The final anchoring is completed by the expansion of the material itself. There is no need to tighten bolts or weld on site. The flexible material can automatically fill and adapt to the slight unevenness or dimensional deviation in the groove during the installation process, which reduces the absolute precision requirements for the processing and installation of the pre-embedded groove, making on-site assembly faster and more reliable.

[0085] After expansion, the flexible expansion strip 331 can tightly fill the gap of the clamping and fixing groove 130, which objectively forms a sealing barrier and helps to improve the airtightness and sound insulation performance of this area. At the same time, its elastomer properties can also provide a certain vibration damping effect, reduce the sharpness of stress transmission, and make the overall structural performance more gentle and durable.

[0086] Additionally, please see Figure 11 and Figure 12 The sliding connector 220 includes a first sliding block 221 fixedly connected to the inner wall panel 210 and a second sliding block 222 snapped into the wall panel mounting groove 140. The first sliding block 221 and the second sliding block 222 are connected on only one side, and a sliding surface 223 is provided at the contact point between the first sliding block 221 and the second sliding block 222.

[0087] Specifically, the first sliding block 221 and the second sliding block 222 can be made of soft materials such as rubber. The second sliding block 222 is inserted into the wall panel mounting groove 140 of the mounting bracket 110. Since the first sliding block 221 and the second sliding block 222 are connected on one side, the inner wall panel 210 and the mounting bracket 110 can be assembled and fixed. The second sliding block 222 and the first sliding block 221 can slide vertically along the sliding surface 223, so that the inner wall panel 210 and the mounting bracket 110 can slide vertically relative to each other under thermal stress, thus avoiding rigid deformation and cracking of the inner wall panel 210.

[0088] It is worth noting that the sliding surface 223 provided between the first sliding block 221 and the second sliding block 222 allows for free vertical sliding. When the heating unit 400 operates and causes the wall panel to expand thermally, this connection allows the entire wall panel to slide smoothly vertically, thereby converting destructive shear stress and compressive stress into harmless directional displacement, fundamentally eliminating the risk of the wall panel body deforming, cracking, or leaking at the joints due to thermal stress.

[0089] The first sliding block 221 and the second sliding block 222 are made of soft materials such as rubber. The flexibility of the material itself provides initial deformation capability, which can absorb instantaneous impact and micro-vibration. It can also act as a damping material to effectively attenuate and isolate the vibration transmitted from the building structure to the wall panel, thereby improving the acoustics of the wall and the comfort of use. In addition, the soft material can always maintain close contact in the sliding groove, forming a dynamic seal to prevent moisture and dust from entering the interior of the wall or the interior space through the installation gaps.

[0090] The first sliding block 221 and the second sliding block 222 are connected on only one side, which ensures that the wall panel unit 200 can slide freely in the vertical direction and provides necessary lateral constraints to prevent the wall panel from shaking. When the temperature decreases and the wall panel shrinks, this connection structure can assist the wall panel to smoothly reset under the action of gravity or material elasticity, ensuring the reliability and durability of the system in repeated hot and cold cycles.

[0091] Please see Figure 13 The heating unit 400 includes a heating plate 410 covering the inner wall panel 210 on the side opposite to the outer wall panel 230. The heating plate 410 is provided with S-shaped heating wires 420, and the two ends of the heating wires 420 are provided with electrical connectors 430.

[0092] Specifically, by placing the heating plate 410 on the side of the inner wall panel 210 away from the outer wall panel 230, the risk of short circuit caused by the invasion of humid and hot gas in the independent cavity can be effectively avoided. The electrical connectors 430 at both ends of the heating wire 420 in the heating plate 410 can be connected in parallel with the external power supply line to supply power to the heating wire 420, thereby realizing the self-heating function of the inner wall panel 210.

[0093] It should be noted that by placing the heating plate 410 and the internal heating wire 420 on the side of the inner wall panel 210 away from the damp independent chamber, the circuit components are completely isolated from the humid airflow processed by the drive component 250 inside the wall panel, eliminating the risk of leakage, short circuit or insulation failure caused by moisture intrusion and condensation accumulation, and ensuring the absolute safety and reliability of the heating function in long-term use.

[0094] The heating wire 420 is distributed in an S-shape within the heating plate 410, which ensures that the heating element is evenly covered on the plate surface, avoiding local hot spots or cold spots. The uniform heat field allows the inner wall panel 210 to expand more evenly due to heat, preventing micro-deformation caused by uneven expansion. At the same time, the uniform temperature distribution also extends the service life of the heating plate 410 itself and the wall panel finish.

[0095] The specific embodiments of the present invention have been described above. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention, all of which are within the protection scope of the present invention.
