Description

Technical Field

[0001] This invention relates to the field of building materials technology, specifically to an anti-condensation metal ceiling panel with a surface rolled micro-pit array. Background Technology

[0002] Conventional flat metal ceilings have smooth, dense surfaces. When the temperature and humidity of the cabin fluctuate, moisture easily spreads continuously on their surface, forming a large water film and condensing. For ships, the high humidity and high salinity of the marine environment, coupled with significant temperature differences between the inside and outside of the cabin, exacerbates condensation. Once condensed water accumulates on the surface and forms large droplets that fall, it will directly soak the electrical equipment, bedding, and interior furnishings below. This not only easily leads to safety hazards such as short circuits and material mold, but also seriously affects cabin functionality and passenger comfort. Therefore, more stringent requirements are placed on the long-term, stable, and drip-proof performance of the ceiling system.

[0003] Furthermore, sea salt aerosols are constantly present in the air inside the ship's cabins. When condensation adheres to the surfaces, it carries chloride salts that remain in various locations. After the moisture evaporates, hard salt crystals precipitate, forming firmly attached salt deposits. These deposits accumulate over time and are difficult to remove on their own, accelerating the corrosion of metal substrates and providing a breeding ground for microorganisms. Since ocean-going vessels have long voyages, manual cleaning is difficult to perform en route, leading to maintenance difficulties and high operating costs.

[0004] To address these issues, a surface-rolled micro-pit array anti-condensation metal ceiling panel is provided. Summary of the Invention

[0005] The purpose of this invention is to provide a surface rolled micro-pit array anti-condensation metal ceiling panel, which solves the problem that existing metal ceiling panels are prone to condensation dripping in high humidity and high salt spray environments.

[0006] The present invention achieves the above objectives through the following technical solutions: A surface-rolled micro-pit array anti-condensation metal ceiling panel includes a metal decorative panel, an insulation core material, and a back panel stacked sequentially. The metal decorative panel, insulation core material, and back panel are surrounded by an isolation frame. The side of the metal decorative panel facing the interior is rolled with micro-pits distributed in an array. The isolation frame has an inwardly extending flange on its side closest to the interior. A drainage groove is formed on the inner side of the flange. Micro-grooves are formed between the micro-pits in the same row to guide the condensate in the micro-pits to flow to the drainage groove. The ceiling panel also includes a washing assembly. The metal decorative panel has an overall inverted V-shaped structure. The washing assembly includes a water storage tank located in the cavity between the metal decorative panel and the insulation core material, and at the top ridge of the inverted V-shaped structure. The water storage tank is used to store cleaning water and release a water curtain to the surface of the metal decorative panel to remove the sediment in the micro-pits.

[0007] As a further optimization of the present invention, the cross-sectional shape of the micro-pit is one of a semi-circle, an inverted cone, or a parabola; the pit diameter of the micro-pit is distributed in a gradient increasing manner along the direction from the central ridge line to the edge of the metal decorative panel.

[0008] As a further optimization of the present invention, the microgrooves are arranged obliquely along the slope of the metal decorative panel, with their lower ends extending to the area above the drainage channel.

[0009] As a further optimization of the present invention, the edge of the metal decorative panel extends downward and is embedded in the cavity of the isolation frame; the edge of the metal decorative panel is provided with sealing rings between its upper and lower surfaces and the inner wall of the isolation frame; the angle between the inclined slopes on both sides of the inverted V-shaped structure of the metal decorative panel and the horizontal plane is set to 20°-30°.

[0010] As a further optimization of the present invention, an installation plate is also provided in the cavity between the metal decorative panel and the thermal insulation core material. The installation plate is fixedly installed on the inner wall of the isolation frame and is used to support and fix the water storage tank.

[0011] As a further optimization of the present invention, both ends of the water storage tank are provided with water replenishment holes, and the water replenishment holes of adjacent ceiling panels are connected and interconnected; a first water outlet is provided at the bottom of the water storage tank, a water inlet is provided at the corresponding position on the back of the metal decorative panel, and a second water outlet is provided on the front of the metal decorative panel that is connected to the water inlet.

[0012] As a further optimization of the present invention, the first water outlet and the second water outlet are both elongated holes extending along the ridge line of the inverted V-shaped structure, and each has multiple holes arranged at intervals along the ridge line.

[0013] As a further optimization of the present invention, the ceiling panel also includes a vibration component for driving the metal decorative panel to generate high-frequency micro-amplitude vibrations; the vibration component includes an installation strip disposed between the metal decorative panel and the insulation core material, and a vibration module fixedly disposed at the bottom of the installation strip; the installation strip is fixedly disposed on the inner wall of the isolation frame, and the output end of the vibration module abuts against the back of the metal decorative panel; elastic columns are provided between the four corners of the metal decorative panel and the installation plate.

[0014] As a further optimization of the present invention, the bottom of the water storage tank is integrally formed with a first docking seat, and the first water outlet is opened on the two side walls of the first docking seat; the metal decorative panel is integrally formed with a second docking seat at the corresponding position, and the water inlet is opened on the side wall of the second docking seat; the vibration component drives the metal decorative panel to move relative to the water storage tank, so that the first water outlet and the water inlet are periodically aligned for conduction or misaligned for interception.

[0015] The beneficial effects of this invention are as follows: 1. This invention effectively segments the condensate film on the surface of the metal decorative panel by setting a micro-pit array structure and micro-grooves, guiding the condensate water to flow and drain in a directional manner, and significantly improving the passive anti-condensation and anti-drip capabilities of the ceiling panel.

[0016] 2. This invention forms a uniform water curtain covering the microstructure area through the rinsing component. Under the rinsing of the water flow, contaminants such as salt crystals and dust are carried out from the micro-pits and micro-grooves and discharged through the drainage channel. This effectively prevents the microstructure from being blocked and maintains its long-term functional stability, solving the problem that the micro-pits are easily blocked by contaminants such as salt crystals and dust during long-term use, leading to functional failure.

[0017] 3. The present invention further improves the self-cleaning effect through a vibration module. On the one hand, the vibration module loosens hardened dirt through high-frequency vibration, and on the other hand, it uses micro-displacement of the plate surface to achieve periodic alignment and misalignment of the first water outlet and the water inlet, simplifying the structure, improving reliability and enhancing cleaning efficiency.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1 To address the issue of condensation dripping from existing metal ceiling panels in high-humidity, high-salt-spray environments, please refer to [link / reference needed]. Figures 1-3 This invention provides an anti-condensation metal ceiling panel with a surface rolled micro-pit array, used in high-humidity and high-salt-spray environments such as ships. It includes a metal decorative panel 1, an insulation core material 2, and a back panel 3 stacked sequentially. An isolation frame 4 is provided around the outer sides of the metal decorative panel 1, insulation core material 2, and back panel 3. The side of the metal decorative panel 1 facing the interior has micro-pits 101 rolled into an array. The diameter of the micro-pits 101 can be 0.3-1.0 mm, and the depth can be 0.1-0.3 mm. The isolation frame 4 has an inwardly extending flange on the side closest to the interior. A drainage groove 401 is formed on the inner side of the flange. A micro-groove 102 is formed between the micro pits 101 in the same row to guide the condensate in the micro pits 101 to flow to the drainage groove 401. The cross-section of the micro-groove 102 is U-shaped or other suitable cross-section. The width of the micro-groove 102 can be 0.2-0.5mm and the depth can be 0.05-0.1mm. A smooth transition structure is provided at the connection with the micro pit 101.

[0022] Under normal operating conditions, when the humidity inside the cabin is high and the surface temperature of the metal panel 1 is below the dew point, water vapor condenses on the side facing the interior. Since the surface of the metal panel 1 is rolled to form an array of micro-pits 101, these micro-pits 101 serve as preferential nucleation sites, effectively capturing the initial condensate droplets. The array of micro-pits 101 segments the continuous water film, preventing large water droplets from falling. Furthermore, the size of the micro-pits 101 is smaller than the critical droplet diameter (usually about 2 mm), thereby inhibiting the formation of large water droplets. At the same time, the micro-pits 101 in the same row are connected by micro-grooves 102. Under the combined action of gravity and surface tension, the condensate continuously migrates towards the edge of the panel along the micro-grooves 102 and eventually flows into the drainage channel 401 formed by the inner side of the flange of the isolation frame 4 and is discharged. There is no risk of dripping throughout the process.

[0023] To address the issue of the micro-pit 101 easily becoming clogged by salt crystals, dust, and other contaminants during long-term use, leading to functional failure, the ceiling panel also includes a washing assembly. The metal decorative panel 1 has an overall inverted V-shaped structure, with the angle between the inclined slopes on both sides of the inverted V-shaped structure and the horizontal plane set at 20°-30°. This angle allows condensate and cleaning water to flow smoothly into the drain trough 401, reducing salt retention and accumulation, preventing water from splashing off the panel surface, while also taking into account the installation space inside the chamber and the overall structural strength. The washing assembly includes a water storage tank 5 located in the cavity between the metal decorative panel 1 and the insulation core material 2, and at the top ridge of the inverted V-shaped structure. The water storage tank 5 is used to store cleaning water and release a water curtain onto the surface of the metal decorative panel 1 to remove sediment from the micro-pit 101.

[0024] When the system is started periodically, the water tank 5 releases a uniform water curtain onto the surface of the metal decorative panel 1. The water flow covers the area of ​​the micro pit 101. Under the action of gravity, the sediment is carried out from the micro pit 101 and micro groove 102, cleaning the surface of the metal decorative panel 1 and guiding it to the drainage tank 401 for discharge, thereby restoring and maintaining the condensate drainage capacity of the microstructure.

[0025] Specifically, the cross-sectional shape of the micro-pit 101 is one of semi-circular, inverted conical, or parabolic; the pit diameter of the micro-pit 101 is distributed in a gradient increasing direction along the metal decorative panel 1 from the central ridge line to the edge of the panel, so as to facilitate the migration of condensate to the edge of the panel.

[0026] The micro-grooves 102 are arranged at an angle along the slope of the metal decorative panel 1, with their lower ends extending to the area above the drainage channel 401 so that water can fall directly into the drainage channel 401.

[0027] To improve overall sealing performance, such as Figures 3-4 As shown, the edge of the metal decorative panel 1 extends downward and is embedded in the cavity of the isolation frame 4; sealing rings 103 are provided between the upper and lower surfaces of the edge of the metal decorative panel 1 and the inner wall of the isolation frame 4. The assembly gap between the metal decorative panel 1 and the isolation frame 4 is completely sealed around the perimeter, so that neither natural condensation water on the panel surface nor rinsing wastewater under self-cleaning conditions can seep into the interior of the ceiling interlayer through the assembly gap. All water can only be confined to the indoor side and discharged uniformly along the drainage channel 401.

[0028] An installation plate 6 is also provided in the cavity between the metal decorative panel 1 and the thermal insulation core material 2. The installation plate 6 is fixed on the inner wall of the isolation frame 4 and is used to support and fix the water storage tank 5.

[0029] like Figure 5As shown, both ends of the water storage tank 5 are provided with water inlet holes 501, and the water inlet holes 501 of adjacent ceiling panels are connected to each other to realize the water circuit connection of multiple ceiling panels; the bottom of the water storage tank 5 is provided with a first water outlet hole 503, the back of the metal decorative panel 1 is provided with a corresponding water inlet hole 105, and the front of the metal decorative panel 1 is provided with a second water outlet hole 106 connected to the water inlet hole 105, forming a water passage from the water storage tank 5 to the front of the metal decorative panel 1.

[0030] The first water outlet 503 and the second water outlet 106 are both elongated holes extending along the ridge line of the inverted V-shaped structure, and each has multiple outlets, which are spaced apart along the ridge line.

[0031] During use, the water storage tank 5 connects with the water storage tank 5 of the adjacent ceiling panel through the water replenishment holes 501 at both ends, thereby connecting the water storage structures of multiple ceiling panels into a continuous water network, facilitating unified water replenishment or level balancing. When cleaning water is needed for the front of the metal decorative panel 1, water flows out from the water storage tank 5 through the first water outlet 503 at the bottom, enters the water inlet 105 on the back of the metal decorative panel 1, and then flows out through the second water outlet 106 connected to it to the front of the metal decorative panel 1, cleaning contaminants on the surface of the micro-pits 101 and maintaining its long-term anti-condensation function, which is especially suitable for high humidity and high salt spray environments in ship cabins.

[0032] Since both the first water outlet 503 and the second water outlet 106 are designed as elongated holes and multiple holes are arranged at intervals along the ridge line, the water outlet area is increased and the uniformity of water flow distribution is improved.

[0033] Example 2 Based on Example 1, in order to further improve the cleaning effect of micro-pit 101, such as Figure 3 , Figures 5-6 As shown, the ceiling panel also includes a vibration assembly for driving the metal decorative panel 1 to generate high-frequency micro-amplitude vibrations; the vibration assembly includes a mounting strip 9 disposed between the metal decorative panel 1 and the insulation core material 2, and a vibration module 7 fixedly disposed at the bottom of the mounting strip 9; the mounting strip 9 is fixedly disposed on the inner wall of the isolation frame 4, and the output end of the vibration module 7 abuts against the back of the metal decorative panel 1; elastic posts 8 are provided between the four corners of the metal decorative panel 1 and the mounting plate 6. It is worth mentioning that the vibration module 7 is preferably a high-frequency micro-amplitude driving element such as a piezoelectric ceramic vibrating plate.

[0034] In addition, the bottom of the water storage tank 5 is integrally formed with a first docking seat 502, and the first water outlet 503 is opened on both side walls of the first docking seat 502; the metal decorative panel 1 is integrally formed with a second docking seat 104 at the corresponding position, and the water inlet 105 is opened on the side wall of the second docking seat 104; the vibration component drives the metal decorative panel 1 to move relative to the water storage tank 5 so that the first water outlet 503 and the water inlet 105 are periodically aligned to conduct or misaligned to cut off the flow.

[0035] When the self-cleaning function is not activated, the vibration module 7 does not work. The metal decorative panel 1 remains in the centered reset state under the elastic support of the four corner elastic columns 8. At this time, the first water outlet 503 on the first docking seat 502 and the water inlet 105 on the second docking seat 104 are completely misaligned and blocked, the water flow is mechanically intercepted, the water storage tank 5 does not release water, and the panel only retains the passive anti-condensation function.

[0036] When the self-cleaning program is started, the piezoelectric vibration module 7 operates at high frequency and applies a small high-frequency vibration to the back of the metal decorative panel 1. Since the four corners of the metal decorative panel 1 are suspended and supported by the elastic columns 8, the panel surface can independently generate a small vibration. The vibration energy is transmitted to each micro pit 101, which continuously acts on the solidified salt scale and other deposits in the pit, and loosens and peels the hard deposits into a loose state. At the same time, the second docking seat 104 moves up and down slightly relative to the first docking seat 502 periodically, so that the first water outlet 503 and the water inlet 105 are periodically aligned and connected or misaligned and intercepted, forming a pulsed water supply effect. A uniform and continuous thin water curtain is formed along the inverted V ridge line through the second water outlet 106, which fully covers and washes the micro pit 101, completely engulfing and carrying away the loosened sediment, which flows into the drainage trough 401 through the micro trench 102 and is discharged, achieving efficient self-cleaning.

[0037] The vibration module 7 is responsible for both the vibration and stripping of hardened dirt in the micro-pit 101 and the mechanical switching of the water circuit through the micro-displacement of the plate surface, eliminating the need for the traditional easily damaged electromagnetic water control valve and improving the rinsing effect.

[0038] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
