[0002] With the development of marine engineering projects, the comfort requirements of crew living areas are constantly increasing, especially the requirements for noise standards are becoming more stringent. As the main place for crew daily life, the environmental quality of the living room is directly related to the crew's work efficiency and physical and mental health. The air distribution unit at the end of the air conditioning and ventilation system directly affects the air distribution and noise level in the room.

[0003] Most existing designs of air distribution units focus on the air flow conveying function, but fail to fully consider noise control and air flow stability. During use, the air volume adjustment is limited to "on" and "off", and the diffuser at the outlet usually needs to be adjusted to the "opening and closing" angle to meet the needs. This will cause a large amount of air turbulence in the air distribution unit box, and the wind speed at the air outlet is too fast, which often generates loud noise due to the turbulent air flow. At the same time, the air flow is unevenly distributed, resulting in poor ventilation in some areas, affecting the living comfort of the crew. Utility Model Content

Detailed Embodiments

[0023] The present invention will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can still be made. These all belong to the protection scope of the present invention.

[0024] As Figures 1-3 shown, the utility model is a disc air distributor with a flow-stabilizing structure, including: a housing 1, a support plate 4, a first partition 5, a flow-blocking partition 6, a porous air duct 7, and a second partition 8; the housing 1 is made of galvanized steel sheet, with a rectangular shape, generally sized 550x450mm, having an air inlet 2 on the side and an air outlet 3 below; as shown in the figure, the right side wall of the first partition 5 is connected to the support plate 4, and the support plate 4 is vertically connected to the inner bottom wall of the housing 1. The support plate 4 serves to separate the air flow channels and support the first partition 5; the first partition 5 is horizontally arranged between the air inlet 2 and the air outlet 3 to guide the air flow to various parts of the air distributor to achieve the dispersion and stabilization of the air flow; on the air flow path between the air inlet 2 and the air outlet 3, a plurality of flow-blocking partitions 6 are arranged in an alternating manner. These partitions generate disturbances when the air flow passes through, thereby stabilizing the air flow and preventing the direct flow from impacting the air outlet 3; the number and arrangement of the flow-blocking partitions 6 are designed according to specific requirements to optimize the distribution and flow effect of the air flow. By setting the support plate 4, the first partition 5, and the alternately arranged flow-blocking partitions 6, the air flow is effectively slowed down and evenly dispersed, avoiding the phenomenon of too fast and disordered air flow, thereby achieving a smooth transition of the air flow; the flow-stabilizing performance of the air distributor is greatly improved, enabling the air to be evenly distributed to the air outlet 3 and ensuring more stable and comfortable air circulation in the use environment.

[0025] A porous air duct 7 is installed at the air inlet 2. A plurality of air outlet holes 71 are provided on the air duct. After the air flow enters the porous air duct 7, it is evenly released into the interior of the housing 1 through the plurality of air outlet holes 71, bypassing the support plate 4, the first partition 5, and the flow-blocking partition 6, and finally flowing out from the air outlet 3. A movable second partition 8 is installed inside the air duct. The second partition 8 can block or open some of the air outlet holes 71 by sliding, thereby adjusting the air intake of the porous air duct 7. By blocking different numbers of air outlet holes 71 with the second partition 8, the air intake of the porous air duct 7 is adjusted, and the air flow is effectively controlled when entering the housing 1, avoiding air flow fluctuations and instability phenomena in the subsequent passages, and helping to maintain the stability of the air flow inside the box.

[0026] In this embodiment, as shown in the figure, the bottom wall of the support plate 4 is fixedly connected to the bottom inner wall of the housing 1, and the other two side walls of the support plate 4 are in close contact with the inner side walls of the housing 1. One side wall of the first partition 5 is connected to the top of the support plate 4, and a certain gap is maintained between the other three sides of the first partition 5 and the inner wall of the housing 1. The air flow entering the interior of the housing 1 needs to pass through the first partition 5 and the flow blocking partition 6 before flowing downward through the gap to the air outlet 3. The air flow bypasses the support plate 4, the first partition 5, and the flow blocking partition 6, and is further dispersed and guided during the flow process, thereby further stabilizing the air flow and avoiding direct impact on the air outlet 3.

[0027] In this embodiment, as shown in the figure, the porous air duct 7 is a cylindrical structure with openings at both ends. The air outlet holes 71 are formed on the peripheral side walls of the porous air duct 7. One end of the porous air duct 7 is connected to and sealed with the right side wall of the support plate 4, and the cross-section of the porous air duct 7 is smaller than that of the support plate 4; the air intake of the air conditioner enters the porous air duct 7 and enters the housing 1 through the air outlet holes 71. Since the bottom is sealed by the support plate 4, the air flow flows upward through the gap between the porous air duct 7 and the housing 1, and flows out through the support plate 4, the first partition 5, and the flow blocking partition 6 to the air outlet 3 below.

[0028] In this embodiment, a diffuser plate 10 is provided at the air outlet 3. The diffuser plate 10 is designed with multiple holes so that the air flow can be more evenly distributed in the entire air outlet area, making the air flow softer and avoiding too strong or too weak local air flow.

[0029] In this embodiment, the four peripheral walls of the second partition 8 are sealed with the four peripheral walls inside the porous air duct 7. By moving the second partition 8, the air outlet holes 71 between the second partition 8 and the support plate 4 are separated from the air inlet end of the porous air duct 7 to block some of the air outlet holes 71, thereby adjusting the air intake volume of the porous air duct 7.

[0030] In this embodiment, as shown in the figure, a limiting frame is connected to the bottom of the first partition 5. The rack 11 is limited to slide between the limiting frame and the first partition 5. A gear 12 is axially connected to the bottom of the first partition 5. The gear 12 meshes with the rack 11. One end of the rack 11 is connected to an adjusting rod 13. The adjusting rod 13 passes through the support plate 4 and is connected to the second partition 8. A rotating handle 14 is connected to the bottom surface of the gear 12. The other end of the rotating handle 14 away from the gear 12 is outside the housing 1. As shown in the figure, the rotating handle 14 is at the diffuser plate 10; by rotating the rotating handle 14, the gear 12 is driven to rotate, so that the adjusting rod 13 drives the second partition 8 to move, adjusting the position of the second partition 8, and further controlling the opening condition of the air outlet holes 71 of the porous air duct 7.

[0031] In one implementation, the limiting frame can be an L-shaped limiting frame. Its vertical wall is connected to the bottom of the first partition 5, and the horizontal wall is used to hold the rack 11. The rack 11 meshes with the gear 12 and is limited within the L-shaped limiting frame.

[0032] In this embodiment, a fiberglass cloth 9 is laid on the inner wall of the housing 1. This material has excellent sound absorption and heat insulation effects and can reduce the noise generated when air flows through.

[0033] Working principle: Rotating the adjusting rod 13 drives the second partition plate 8 to move through the gear 12 and the rack 11, adjusting the position of the second partition plate 8. The second partition plate 8 isolates the air outlet holes 71, thereby adjusting the air intake volume of the porous air duct 7; the air intake of the air conditioner enters the housing 1 through the air outlet holes 71 of the porous air duct 7. A part of the air flow bypasses the support plate 4 and flows through the path between the first partition plate 5 and the flow blocking partition plate 6, and flows from the gap between the first partition plate 5 and the housing 1 to the lower part of the first partition plate 5; a part of the air flow bypasses the support plate 4, that is, flows from the gaps between the front and rear side walls of the first partition plate 5 and the housing 1 to the lower part of the first partition plate 5; all the air flows finally converge into the air outlet 3 and flow out through the diffuser plate 10. By setting the support plate 4, the first partition plate 5 and the alternately arranged flow blocking partition plates 6, the air flow is effectively slowed down and evenly dispersed, avoiding the phenomenon of too fast and disordered air flow, thereby realizing the smooth transition of the air flow; the flow stabilizing performance of the air distributor is greatly improved, so that the air is evenly distributed to the air outlet 3, ensuring more stable and comfortable air circulation in the use environment.
