Description

Technical Field

[0001] This invention relates to wall panels, and more particularly to an active dehumidifying wall panel. Background Technology

[0002] With increasing demands for improved living environments, wall panels have become widely used in interior decoration. However, in humid climates (such as during the rainy season or the "return to spring" period), prolonged high humidity can easily cause wall panels to become damp, moldy, or even swell and deform. To address this issue, most existing moisture-proof wall panels in the industry employ an internal pure electric heating drying method. For example, Chinese Patent Publication No. CN220451292U discloses a wall panel whose structure includes a panel body, a mounting plate connected to the back of the panel body to form a mounting cavity, and a heating element built into the mounting cavity. This technical solution attempts to use the heating element to generate heat, forcibly evaporating the moisture absorbed by the panel body, in order to achieve the purpose of dehumidification and moisture prevention.

[0003] However, when the high-temperature, high-humidity water vapor generated by heating evaporates and circulates within the sealed installation cavity, it inevitably condenses naturally upon encountering the low-temperature installation plate close to the building's solid wall. This condensation turns into liquid water droplets that slide off and accumulate in large quantities at the bottom of the wall panel. Current technology lacks a drainage structure, resulting in the bottom of the wall panel being constantly submerged in water, which easily leads to rot at the base of the panel and internal electrical short circuits. Secondly, if a traditional electronic micro-pump is added to the bottom of the cavity for water extraction, the pump motor and sensors are highly susceptible to moisture damage, rust, and short-circuiting failure under the harsh alternating high-temperature and high-humidity conditions inside the wall panel. This results in extremely low system reliability and high disassembly and maintenance costs. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide an active dehumidifying wall panel that uses a single heat source to drive a purely mechanical linkage without additional electronic energy consumption. Through one feature, it simultaneously achieves the dual effects of active gaseous dehumidification and directional liquid drainage, thus completely solving the problem of damp walls.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: an active dehumidifying wall panel, comprising a panel body and an mounting plate connected to one side surface of the panel body and forming a mounting cavity with the panel body. The mounting cavity contains heating elements connected to the mounting plate at both ends. It also includes a bidirectional phase change linkage assembly closely attached to the heating elements, an exhaust valve located at the top of the mounting plate, and a flow guiding assembly located at the bottom of the mounting cavity. The bidirectional phase change linkage assembly includes a bidirectional expansion cylinder closely attached to the surface of the heating elements and sealed with a phase change liquid inside, an upper push rod connected to the top of the bidirectional expansion cylinder, and a lower push rod connected to the bottom of the bidirectional expansion cylinder. The bidirectional expansion cylinder is fixed to the mounting plate. The flow guiding assembly includes a water collection tank, a flexible water inlet hose connected at one end to the bottom of the water collection tank, and a flexible squeezing water bladder connected at the other end of the flexible water inlet hose. The phase change liquid expands due to the heating element, driving the upper push rod to slide upward and simultaneously driving the lower push rod to slide downward. The lower section of the lower push rod has a laterally protruding elastic clamping component. When the upper push rod slides upward, its top end pushes open the exhaust valve. When the lower push rod slides downward, the elastic clamping component first presses against the flexible water inlet hose and undergoes elastic contraction to absorb excess stroke and maintain the hose in a cut-off state. Then, the lower push rod continues to descend, pressing against and squeezing the flexible squeezing water bladder.

[0006] To achieve the above technical solution, the heating element heats up the liquid in the bidirectional expansion cylinder, causing a physical phase change and volume expansion. This drives the upper push rod to slide upwards, opening the exhaust valve and enabling the active discharge of high-temperature and high-humidity moisture from the installation cavity. Simultaneously, the lower push rod slides downwards, using its elastic clamping component to first block the flexible water inlet hose. Then, the lower push rod mechanically squeezes the flexible water-squeezing bladder, directing the accumulated condensate out through the flexible water inlet hose. This process converts thermal energy into mechanical energy, achieving the technical effect of automatically completing the simultaneous operation of exhaust and drainage without electrical drive, effectively preventing the accumulation of condensate at the bottom of the wall panel.

[0007] As a preferred embodiment of the present invention, the elastic clamping assembly includes a guide sleeve fixed to the side wall of the lower push rod, a pressure block slidably connected inside the guide sleeve, and a first elastic element connected between the pressure block and the inner wall of the guide sleeve, wherein the pressure block is positioned opposite the flexible water inlet hose.

[0008] To achieve the above technical solution, an elastic clamping assembly consisting of a guide sleeve, a pressure block, and a first elastic element is installed on the side wall of the lower push rod. This ensures that during the initial downward movement of the lower push rod, the pressure block, under the pre-tightening force of the first elastic element, preferentially presses against and cuts off the flexible water inlet hose. In subsequent strokes, the compression of the first elastic element absorbs excess displacement of the lower push rod. This achieves the technical effect of ensuring that the water bladder is completely sealed at the inlet before being pressurized, preventing liquid backflow into the collection tank during the squeezing process, and guaranteeing the unidirectional and stable drainage.

[0009] As a preferred embodiment of the present invention, the bottom outlet of the flexible squeezing water bladder is connected to a drainage hose, and the end of the drainage hose is provided with a duckbill-type one-way valve that is open in one direction outward. When the flexible squeezing water bladder is squeezed by the lower push rod, the internal fluid rushes open the duckbill-type one-way valve and is discharged in a directional manner.

[0010] To achieve the above technical solution, a duckbill-type check valve is installed inside the drainage hose at the bottom of the flexible squeeze water bladder. Utilizing the duckbill-type check valve's characteristic of only allowing outward flow, the internal fluid can smoothly open the valve and drain when the flexible squeeze water bladder is pressurized, while preventing the backflow of external moisture or liquid in the non-pressurized state. This structure achieves the technical effect of directional drainage and maintaining a sealed environment at the bottom of the mounting cavity, further enhancing the system's moisture-proof performance.

[0011] As a preferred embodiment of the present invention, the top of the mounting plate is provided with an exhaust hole, the exhaust valve includes a baffle plate hinged to the exhaust hole and a second elastic member connecting the baffle plate and the inner wall of the mounting plate, and the top end of the upper push rod movably abuts against the lower surface of the baffle plate.

[0012] To achieve the above technical solution, an exhaust valve with a baffle plate and a second elastic element is installed on the top of the mounting plate, and the top of the upper push rod is movably abutted against the baffle plate, thus realizing the normally closed exhaust port and its opening when heated. When the upper push rod is pushed upward, the baffle plate passively overcomes the elastic force of the second elastic element and opens, achieving the technical effect of timely depressurization and discharge of high-temperature and high-humidity gas. After heating stops, the exhaust valve automatically resets under the action of the second elastic element to prevent external moisture from re-entering.

[0013] As a preferred embodiment of the present invention, a first return spring is sleeved between the top of the bidirectional expansion cylinder and the upper push rod, and a second return spring is sleeved between the bottom of the bidirectional expansion cylinder and the lower push rod.

[0014] To achieve the above technical solution, a first return spring and a second return spring are respectively installed between the top of the bidirectional expansion cylinder and the upper push rod, and between the bottom of the bidirectional expansion cylinder and the lower push rod. The restoring force of the springs ensures that the upper and lower push rods quickly return to their initial positions after the heating element stops heating and the phase-change liquid cools and contracts. This achieves the technical effect of giving the entire exhaust and drainage system a cyclical reset capability, ensuring the repeatability of the dehumidification operation.

[0015] As a preferred embodiment of the present invention, a condensing back plate is connected to the inner wall of the side of the mounting plate opposite to the plate body, and the condensing back plate is located on the side of the heating element.

[0016] To achieve the above technical solution, a condensing backplate is installed on the inner wall of the mounting plate on the side opposite to the plate body. The temperature difference between the condensing backplate and the heating element induces the gaseous water mist in the mounting cavity to condense in a specific area. This achieves the technical effect of changing "random condensation" to "directional condensation," effectively controlling the generation location of liquid water inside the mounting cavity and facilitating subsequent unified collection.

[0017] As a preferred embodiment of the present invention, the surface of the condenser back plate is provided with a guide groove, and the bottom end of the guide groove extends downward and communicates with the water collection tank.

[0018] To achieve the above technical solution, a guide channel extending downwards and connecting to the water collection tank is opened on the surface of the condenser back plate. Gravity is used to guide the condensate along the guide channel and quickly flow into the water collection tank, greatly improving the condensate collection efficiency.

[0019] As a preferred embodiment of the present invention, the outer wall of the bidirectional expansion cylinder is coated with a graphene thermally conductive patch, and the graphene thermally conductive patch is bonded to the outer wall of the heating element.

[0020] To achieve the above technical solution, a graphene thermally conductive patch is laminated onto the outer wall of the bidirectional expansion cylinder and attached to the heating element. The extremely high thermal conductivity of graphene rapidly conducts the heat generated by the heating element to the interior of the bidirectional expansion cylinder. This achieves the technical effect of shortening the response time of the bidirectional phase change linkage component, ensuring a high degree of synchronization between the exhaust and drainage processes and the heating and dehumidification processes.

[0021] As a preferred embodiment of the present invention, the side of the plate facing the mounting cavity is covered with a heat-insulating reflective film, and the heat-insulating reflective film is disposed between the plate and the heating element.

[0022] To achieve the above technical solution, a heat-insulating and reflective film is covered on the side of the panel facing the mounting cavity. Utilizing the film's heat reflection and insulation properties, the panel is protected from high-temperature damage, and heat is reflected back into the mounting cavity. This achieves the technical effects of reducing the surface temperature of the panel and improving the heating efficiency within the mounting cavity. Attached Figure Description

[0025] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and mastered.

[0026] An active dehumidifying wall panel includes a panel body 1 and a mounting plate 2 fixedly connected to the back of the panel body 1, with the front of the panel body 1 facing the indoor space. The mounting plate 2 and the panel body 1 form an installation cavity.

A heating element 4, preferably a carbon fiber heating tube, is centrally located inside the mounting cavity and connected to the mounting plate 2 at both ends. The heat-insulating reflective film 3 is positioned between the plate 1 and the heating element 4 to directionally reflect the heat radiation generated by the heating element 4 into the mounting cavity, thereby improving heat utilization efficiency and preventing the plate 1 from warping or deforming due to heat.

The exhaust valve 6 specifically includes a baffle plate 7 hinged to the exhaust hole 5, and a second elastic element 8 connecting the baffle plate 7 and the inner wall of the mounting plate 2. The second elastic element 8 is preferably a stainless steel return torsion spring.

[0029] In the middle of the mounting cavity, a condensing back plate 9 is fixedly connected to the inner wall of the mounting plate 2 on the side opposite to the plate body 1. The condensing back plate 9 is preferably an aluminum alloy plate with an anodized surface. The condensing back plate 9 is located to the side of the heating element 4 to avoid direct exposure to the high temperature of the heating element 4 and to make full use of the natural low temperature of the solid wall surface.

[0030] The surface of the condenser back plate 9 is provided with a flow guide groove 10, and the cross-section of the flow guide groove 10 is triangular.

[0031] A bidirectional phase change linkage assembly 11, serving as the core power source, is disposed close to the heating element 4. The bidirectional phase change linkage assembly 11 includes a bidirectional expansion cylinder 12 that is attached to the surface of the heating element 4 and is sealed internally with a phase change liquid. The bidirectional expansion cylinder 12 is fixed to the mounting plate 2. The cylinder body is preferably a fatigue-resistant beryllium bronze bellows, and the phase change liquid is preferably a fluorinated liquid with a boiling point between 50 and 60 degrees Celsius.

[0032] A graphene thermally conductive patch 13 is laminated on the outer wall of the bidirectional expansion cylinder 12. The graphene thermally conductive patch 13 is tightly attached to the outer wall of the heating element 4 to achieve transient heat transfer with extremely low thermal resistance.

[0033] An upper push rod 14 is slidably connected to the top of the bidirectional expansion cylinder 12, and a lower push rod 15 is slidably connected to the bottom. Both the upper push rod 14 and the lower push rod 15 are preferably made of aerospace aluminum alloy. The top end of the upper push rod 14 extends upward and movably abuts against the lower surface of the wind deflector 7. A first return spring 16 is connected between the top of the bidirectional expansion cylinder 12 and the upper push rod 14.

[0034] A second return spring 17 is connected between the bottom of the bidirectional expansion cylinder 12 and the lower push rod 15. A laterally protruding elastic clamping assembly 18 is connected to the outer wall of the lower push rod 15.

[0035] The elastic clamping assembly 18 includes a guide sleeve 20 fixed to the side wall of the lower push rod 15, a pressure block 21 slidably connected within the guide sleeve 20, and a first elastic element 22 connected between the pressure block 21 and the inner wall of the guide sleeve 20. The end of the pressure block 21 has a rounded chamfer to prevent cutting the hose, and the pressure block 21 is positioned directly opposite the flexible water inlet hose 25.

[0036] A flow guiding assembly 23 is provided at the bottom of the mounting cavity. The bottom end of the flow guiding groove 10 on the surface of the condenser back plate 9 extends downward and communicates with the water collection tank 24 in the flow guiding assembly 23. The water collection tank 24 is preferably injection molded from ABS engineering plastic. A flexible water inlet hose 25 is connected to the bottom of the water collection tank 24, preferably a high-resilience liquid silicone hose. The other end of the flexible water inlet hose 25 is connected to a flexible squeeze water bladder 26, which is preferably made of EPDM rubber resistant to deformation fatigue and is arranged directly below the lower push rod 15. The bottom outlet of the flexible squeeze water bladder 26 is connected to a drain hose (not shown in the figure). A one-way outward-facing duckbill-type check valve 27 is fixed to the end of the drain hose. The duckbill-type check valve 27 is preferably a medical-grade silicone check valve to prevent external moisture from flowing back into the cavity.

[0037] In actual dynamic operation, the heating element 4 is electrically connected to an intermittent temperature control module. The intermittent temperature control module uses a conventional time relay or a constant temperature bimetallic strip switch to control its periodic pulse-type start and stop. During the power-on heating phase, the moisture inside the cavity evaporates upon heating and condenses on the condenser back plate 9, flowing into the water collection tank 24. Simultaneously, the phase change liquid expands upon heating, driving the upper push rod 14 to open the exhaust valve 6 to discharge hot and humid gas. At the same time, it drives the pressure block 21 on the lower push rod 15 to cut off the flexible water inlet hose 25 first, and then continues to descend to squeeze the flexible squeezing water bladder 26 to complete directional drainage. When the set threshold is reached and the power-off cooling phase is entered, the phase change liquid cools and contracts. The upper and lower push rods retract rapidly under the action of the reset spring, and the exhaust valve 6 automatically closes to prevent external moisture from flowing back in. At the same time, the lower push rod 15 moves upward to reconnect the flexible water inlet hose 25. After losing pressure, the flexible squeezing water bladder 26 returns to its original shape by elasticity and generates internal negative pressure to draw water in, sucking the newly collected condensate into the water bladder. The system uses this pulse-like alternating cycle to completely avoid the mechanism lock-up and water accumulation caused by continuous heating under extreme high humidity conditions, achieving stable and continuous active pumping dehumidification.

[0038] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
