Description

Technical Field

[0001] The present invention relates to the technical field of marine wind cabinets, and in particular to a noise-reducing and silent marine wind cabinet. Background Art

[0002] Marine air cabinets are key components of a ship's ventilation system, playing a vital role. They distribute treated air evenly throughout the ship's cabins, ensuring a comfortable environment for crew and passengers. Whether in scorching seas or freezing weather, they precisely regulate air temperature and humidity.

[0003] The existing Chinese patent with publication number CN218617153U discloses a marine noise reduction wind device, including a shell, an air inlet duct mounted on the shell, an adjustment mechanism mounted inside the shell for controlling the amount of air delivered by the air inlet duct to the inside of the shell, and a handle mounted on the bottom of the shell and assembled with the adjustment mechanism; the shell includes a shell, an air inlet guide plate arranged inside the shell and cooperating with the air inlet duct, a middle partition arranged in the middle of the shell and dividing the shell into two layers, a double-layer sound-absorbing plate staggered above the middle partition so that the upper layer of the shell forms a curved air duct, and a handle arranged at the bottom of the shell. Diffuser plate; this utility model uses the air inlet guide plate to evenly diffuse the airflow, and uses the staggered double-layer sound-absorbing partitions to bend, slow down, and reduce noise on the airflow, without affecting the air intake and outlet, so that the noise is significantly reduced, and the structure is simple and meets the use requirements. However, when reducing the noise of the sea breeze, this patent disperses the wind through the mesh, but when the wind contacts the mesh, since one side of the mesh is a plane, the movement state of the airflow changes, causing the airflow to collide and rub with one side of the mesh. The friction of the airflow and the contact area with one side of the mesh are large, thereby generating noise, resulting in the problem of unsatisfactory noise reduction effect.

[0004] Therefore, we propose a noise-reducing and silent marine wind cabinet. Summary of the Invention

[0018] The present invention proposes a noise-reducing and silent ship wind cabinet. When the wind cabinet body is used, after the external wind is drawn into the air inlet pipe by the fan, the collar absorbs the moisture in the air flow. Since the moisture absorption plate is also provided with multiple groups of filter holes, the larger particle impurities will be retained on the surface of the diverter plate, while the smaller particles will be isolated by the activated carbon filter and fall into the filter holes opened in the moisture absorption plate. The start-up of the motor drives the driving rod A and the rotating plate to rotate, and the rotating rotating plate will sweep away the impurities remaining in the filter holes. The driving rod A will move the U-shaped plate up and down to remove impurities attached to the surface of the bristles. Since the diverter plate is triangular in shape, the airflow will move along the diverter plate when it contacts the diverter plate, thereby reducing noise. The diverter plate is also sprayed with polytetrafluoroethylene to reduce the friction coefficient, further reducing noise. The filtered airflow will pass through the fan and flow into the air pipe, where it will be further dehumidified and filtered by the sponge. Finally, the airflow will flow out from the inside of the outlet pipe and finally out from the other end of the outlet pipe, thereby reducing the noise generated by the air distribution unit body during operation.

[0041] A diverter ring 1481 is fixedly installed on the inner wall of the air outlet pipe 148, and a spiral groove 1482 is provided on the upper surface of the diverter ring 1481. A plurality of water leakage ports 1483 are provided through the bottom of the spiral groove 1482. The released water can flow in a spiral shape through the spiral groove 1482, and finally the water can adhere to the inner wall of the air outlet pipe 148 through the water leakage ports 1483, thereby cleaning the inner wall of the air outlet pipe 148.

[0042] The output ends of the motor 3 are respectively connected to the driving rod A31 and the driving rod B34 for rotation. The outer surface of the driving rod A31 is fixedly installed with a vertical plate 32. There are four groups of vertical plates 32. One end of the four groups of vertical plates 32 is fixedly installed with a magnet 33. The magnet 33 and the ladder block 1224 magnetically repel each other. The outer surface of the driving rod B34 is fixedly installed with a rotating plate 35. There are four groups of rotating plates 35. The inner wall of the four groups of rotating plates 35 is fixedly installed with multiple groups of bristles 36. The ladder block 1224 is directly below the bristles 36. The driving rod A31 and the rotating plate 35 can allow the rotating plate 35 to carry the bristles 36 to process the impurities on the surface of the diverter plate 1246, and then the impurities attached to the surface of the bristles 36 can be processed by the lifting of the ladder block 1224.

[0043] Working principle: When the air distribution unit body 1 is working, when the fan 13 is started to draw air into the air inlet pipe 12, the airflow will contact the diverter plate 1246 and move along its surface. Since the diverter plate 1246 is triangular in shape, the contact area with the airflow is small. In addition, the surface of the diverter plate 1246 is sprayed with polytetrafluoroethylene to reduce the friction coefficient, thereby reducing the generation of noise. When the airflow passes through the diverter plate 1246, the moisture absorption plate 1245 will absorb the moisture contained in the airflow, thereby further drying the air. Since the surface of the moisture absorption plate 1245 is also provided with filter holes, the airflow passing through the moisture absorption plate 1245 will contact the activated carbon filter 1242, and the activated carbon filter 1242 will remove the moisture in the airflow. The remaining impurities are isolated in one part, and the impurities isolated by the activated carbon filter 1242 will fall into the filter hole opened by the moisture absorption plate 1245. At this time, the motor 3 turned on in advance will slowly rotate with the driving rod A31 and the driving rod B34, and the rotating plate 35 on the outer surface of the driving rod B34 will use the bristles 36 on one side to clean the impurities in the filter hole, and some impurities will adhere to the surface of the bristles 36. At this time, the vertical plate 32 on the outer surface of the driving rod A31 will also rotate with the magnet 33, and the ladder block 1224 inside the annular plate 122 will repel the magnet 33, allowing the U-shaped plate 1222 to descend with the ladder block 1224. At this time, the ladder block 1224 will follow the rotating plate 3 5 The inner wall of the brush 36 descends to scrape off the impurities. When the magnet 33 and the ladder block 1224 are not in the same vertical line, the tension spring 1223 will lift the U-shaped plate 1222 and wait for the next repulsion to continue to remove the impurities on the surface of the bristles 36. The removed impurities fall into the hole opened by the V-tube A121 and finally fall into the inside of the discharge chute 19. They are then collected by the collection box 18. The airflow passing through the activated carbon filter 1242 will follow the fan 13 to the inside of the air delivery pipe 14. After that, the sponge 143 that initially stays in the inside of the air delivery pipe 14 will further discharge the remaining moisture and impurities in the airflow. Finally, the airflow will be discharged from the outlet pipe 148. When the air distributor body 1 is no longer needed, the adsorbed moisture reaches saturation. Sponge 143, move the dial plate 147 to let the magnetic plate 146 move with the iron ring 142, insert the diamond hole 144 into the diamond plate 1454, and then pull the slide plate 1453 at the same time to let the diamond plate 1454 squeeze the sponge 143 so that the saturated sponge 143 will squeeze out the water, and the squeezed water will flow along the inner wall of the air outlet pipe 148, and the water will flow into the spiral groove 1482, and finally flow in a spiral shape. Because there are multiple groups of water leakage ports 1483 at the bottom of the spiral groove 1482, the water at this time will adhere to the inner wall of the air outlet pipe 148, thereby cleaning the inner wall of the air outlet pipe 148, and finally flow out from the other end of the air outlet pipe 148, thereby reducing the noise generated by the air distributor body 1 during operation.

[0044] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
