Description

Active dehumidification dado Technical Field The invention relates to a wallboard, in particular to an active dehumidifying wallboard. Background Along with the improvement of the requirements of people on living environment, the wall panels are widely applied to interior decoration. However, in areas where the climate is humid (such as the "rainy season" or the "southerly"), the prolonged high humidity environment is extremely liable to cause the panel to become wet, moldy and even to expand and deform. In order to solve the problem, the prior dampproof wall panels in the industry mostly adopt an internal pure electric drying scheme. For example, chinese patent publication No. CN220451292U discloses a panel, which includes a panel body, a mounting plate connected to the back surface of the panel body to form a mounting cavity, and a heating member built in the mounting cavity. According to the technical scheme, the heating element is electrified to generate heat, so that the water vapor absorbed by the plate body is forcedly heated and evaporated, and the aim of dehumidification and moisture prevention is fulfilled. However, when the high-temperature and high-humidity water vapor evaporated by heating is dissociated in the sealed installation cavity, the water vapor meets the low-temperature installation plate close to the solid wall of the building, and natural condensation is inevitably generated, and the water vapor slides down to form liquid water droplets and is deposited at the bottom of the wall panel in a large amount. The prior art lacks a diversion liquid discharging structure, so that the bottom of the panel is soaked in water for a long time, and the root rot and internal electrical short circuit of the panel are easily caused. Secondly, if the traditional electronic miniature water pump is additionally arranged at the bottom of the cavity to pump water, under the severe alternating working condition of long-term high temperature and high humidity inside the wall protection plate, the water pump motor and the sensor are extremely easy to be affected by damp, rust and short circuit failure, the system reliability is extremely low, and the disassembly, assembly and maintenance costs are high. Disclosure of Invention In view of the above, the present invention aims to provide an active dehumidifying panel, which uses a single heat source to drive pure mechanical linkage, has no additional electronic energy consumption, and simultaneously realizes the dual effects of active gaseous dehumidifying and directional liquid draining by one feature, thereby thoroughly solving the problem of wall surface wetting.
