Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a silencer valve and an air conditioning unit. Background Technology

[0002] A silencer is a noise reduction device used in airflow ducts that simultaneously transmit noise. It utilizes pipes with sound-absorbing linings, bends, or pipes with sudden changes in cross-sectional area or other discontinuous acoustic impedance to attenuate or reflect noise back into the duct. The former is called a resistive silencer, and the latter a reactive silencer; there are also composite impedance silencers. An airflow regulating valve, also called a damper, is an indispensable central air conditioning terminal accessory in ventilation, air conditioning, and air purification projects in industrial plants and civil buildings. It is generally used in air conditioning and ventilation system ducts to regulate the airflow of branch pipes and can also be used for the mixing and regulation of fresh and return air.

[0003] To meet the market demand for products that simultaneously possess noise reduction and enclosed air duct functions, such as Figure 1 As shown, a silencer 11 is usually placed in a separate functional section of the air conditioning unit, while an air volume regulating valve 12 is used at the air outlet. However, when the air conditioning unit has a compact structure, the air volume regulating valve 12 and the silencer 11 may not be able to be used together.

[0004] Therefore, there is an urgent need to propose a silencer valve and air conditioning unit to solve the above problems. Utility Model Content

[0022] Another objective of this invention is to provide an air conditioning unit that solves the problem that the air volume regulating valve and the silencer cannot be used together when the overall structure of the air conditioning unit is relatively compact.

[0023] To achieve this objective, the present invention adopts the following technical solution:

[0025] The beneficial effects of this utility model are:

[0026] This utility model provides a silencer damper applied to a generator unit. The silencer damper includes a fixing mechanism, a silencer, and a linkage mechanism. The fixing mechanism includes a frame, a first fixing plate, and a second fixing plate. The linkage mechanism includes a first connecting rod and a second connecting rod. When the generator unit is operating normally, the silencer is in the air-guiding state. At this time, the side of the silencer is spaced apart from the inner surface of the frame, and the silencer serves to reduce noise. Simultaneously, the silencer also acts as a guide plate for the airflow regulating valve, guiding the airflow direction. When the generator unit stops operating, the first connecting rod pulls the second connecting rod, causing the silencer to rotate and enter a closed state. At this time, the side of the silencer abuts against the inner surface of the frame, and the silencer seals the frame and closes the air duct. By using the silencer as a guide plate for the airflow regulating valve, the silencer achieves both noise reduction and air duct closure functions while also reducing the overall size of the silencer damper.

[0027] This embodiment also provides an air conditioning unit, including a housing and a silencer valve. By applying a silencer valve with a smaller overall size to the air conditioning unit, the overall structure of the air conditioning unit becomes more compact, solving the problem that the air volume regulating valve and the silencer cannot be used together when the overall structure of the air conditioning unit is compact.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] This embodiment provides a silencer valve that, while satisfying the requirement of using an airflow regulating valve and a silencer together, achieves the effect of reducing the size of the silencer valve.

[0042] Specifically, such as Figures 2 to 6 As shown, a silencer valve 13 is applied to a generator unit. The silencer valve 13 includes a fixing mechanism 20, a silencer 30, and a linkage mechanism. The fixing mechanism 20 includes a frame 21, a first fixing plate 22, and a second fixing plate 23. The side surfaces of the first fixing plate 22 and the second fixing plate 23 are respectively connected to the inner surfaces of opposite sides of the frame 21. The silencer 30 has a plate-like structure, and its two ends are rotatably connected to the first fixing plate 22 and the second fixing plate 23 respectively. The silencer 30 can be rotated... The movable enclosed frame 21; the linkage mechanism includes a first link 41 and a second link 42. The first link 41 is slidably connected to the side of the first fixed plate 22 away from the second fixed plate 23. One end of the second link 42 is fixedly connected to one end of the silencer 30, and the other end of the second link 42 is rotatably connected to the first link 41. When the side of the silencer 30 is spaced apart from the inner surface of the frame 21, it is defined as the air guiding state. When the side of the silencer 30 abuts against the inner surface of the frame 21, it is defined as the closed state.

[0043] When the unit is operating normally, the silencer 30 is in the air-guiding state. At this time, the side of the silencer 30 is spaced apart from the inner surface of the frame 21, and the silencer 30 plays a role in noise reduction. At the same time, the silencer 30 also acts as a guide plate for the airflow regulating valve 12, guiding the airflow direction. When the unit stops operating, the first connecting rod 41 pulls the second connecting rod 42, causing the silencer 30 to rotate, so that the silencer 30 is in the closed state. At this time, the side of the silencer 30 abuts against the inner surface of the frame 21, and the silencer 30 plays a role in sealing the frame 21 and closing the air duct. By using the silencer 30 as a guide plate for the airflow regulating valve 12, the silencer 30 has the dual functions of noise reduction and air duct sealing, while reducing the size of the entire silencer valve 13. It should be noted that when one side of the silencer 30 abuts against the inner surface of the frame 21, the inner surface of the frame 21 on the opposite side also abuts against the side of the silencer 30 (the other side of the same silencer 30, or one side of another silencer 30). This is a common technical means for enclosed air ducts, and will not be elaborated here.

[0044] Furthermore, the linkage mechanism also includes a third link ( Figure 2 (not shown in the image) and the fourth link ( Figure 2 (Not shown in the image) The third link is slidably connected to the side of the second fixed plate 23 away from the first fixed plate 22. One end of the fourth link is fixedly connected to the other end of the muffler 30, and the other end of the fourth link is rotatably connected to the third link. Linkage mechanisms are provided at both ends of the muffler 30. The fourth link and the second link 42 cooperate to rotate the muffler 30, making the rotation of the muffler 30 smoother.

[0045] Furthermore, to achieve the connection between the muffler 30 and the first fixed plate 22 and the second fixed plate 23, a first groove 31 is provided at one end of the muffler 30, and a first through hole is provided on the first fixed plate 22. The linkage mechanism also includes a first connector 43 and a second connector 44. One end of the first connector 43 is fixedly connected to one end of the second connecting rod 42, and the other end of the first connector 43 is rotatably inserted through the first through hole and fixedly connected to the groove wall of the first groove 31. The other end of the second connecting rod 42 is rotatably connected to the first connecting rod 41 through the second connector 44. The other end of the muffler 30 is provided with a second groove, and a second through hole is provided on the second fixed plate 23. The linkage mechanism also includes a third connector and a fourth connector. One end of the third connector is fixedly connected to one end of the fourth connecting rod, and the other end of the third connector is rotatably inserted through the second through hole and fixedly connected to the groove wall of the second groove. The other end of the fourth connecting rod is rotatably connected to the third connecting rod through the fourth connector.

[0046] In other embodiments, one end of the muffler 30 is provided with a first groove 31, and the other end is provided with a rotating shaft. One end of the first connecting member 43 is fixedly connected to one end of the second connecting rod 42, and the other end of the first connecting member 43 rotatably passes through the first through hole and is fixedly connected to the groove wall of the first groove 31. The rotating shaft rotatably passes through the second through hole and is fixedly connected to one end of the second connecting rod 42. Alternatively, both ends of the muffler 30 are provided with rotating shafts. In this embodiment, the first connecting member 43 is cylindrical; in other embodiments, the first connecting member 43 is annular. In this embodiment, the second connecting member 44 is cylindrical; in other embodiments, the second connecting member 44 is annular.

[0047] Optionally, the number of silencers 30 is at least two, and the number of second connecting rods 42 is equal to and corresponds one-to-one with the number of silencers 30. By controlling the rotation of at least two silencers 30, the silencers 30 cooperate to enhance the windward guidance effect and further improve the sealing effect of the air duct. The one-to-one correspondence between the second connecting rods 42 and the silencers 30 improves the control over the rotation of the silencers 30, making the rotation of the silencers 30 smoother. In this embodiment, the number of silencers 30 and the number of second connecting rods 42 are both 7. In other embodiments, the number of silencers 30 and the number of second connecting rods 42 can both be 2, 5, or 9, etc.

[0048] Furthermore, the number of fourth links is equal to and corresponds one-to-one with the number of mufflers 30. The fourth links and the second links 42 are located at opposite ends of the same muffler 30 and rotate in coordination, making the rotation of the muffler 30 smoother. In this embodiment, there are 7 fourth links; in other embodiments, the number of fourth links can be 2, 4, or 8, etc.

[0049] Furthermore, at least two mufflers 30 are evenly spaced along a first direction, which is the length direction of the fixed plate. The distance between two adjacent mufflers 30 is equal, so that the rotation angles of two adjacent mufflers 30 are equal, further improving the sealing effect between two adjacent mufflers 30. In other embodiments, the first direction may be the width direction of the fixed plate.

[0050] Optionally, the side surfaces of the first fixing plate 22 and the second fixing plate 23 are detachably connected to the inner surfaces of opposite sides of the frame 21, making it easier to disassemble the first fixing plate 22, the muffler 30 and the second fixing plate 23, thereby facilitating the disassembly, assembly and maintenance of the muffler 30 connected to the first fixing plate 22 and the second fixing plate 23.

[0051] Furthermore, the first fixing plate 22 is provided with a first slide rail 221, and the inner surface of the frame 21 is provided with a first slide groove, the first slide groove being slidably and detachably connected to the first slide rail 221; the second fixing plate 23 is provided with a second slide rail 231, and the inner surface of the frame 21 is provided with a second slide groove, the second slide groove being slidably and detachably connected to the second slide rail 231. In other embodiments, the first fixing plate 22 is provided with a first slide rail 221, the inner surface of the frame 21 is provided with a first slide groove, the first slide groove being slidably and detachably connected to the first slide rail 221, and the second fixing plate 23 is magnetically connected to the frame 21; or, the first fixing plate 22 is magnetically connected to the frame 21, the second fixing plate 23 is provided with a second slide rail 231, the inner surface of the frame 21 is provided with a second slide groove, and the second slide groove being slidably and detachably connected to the second slide rail 231.

[0052] Optionally, the silencer 30 has a rectangular cross-section with two short sides forming an irregular hexagonal shape with isosceles triangles. As a guide plate for the airflow regulating valve 12, the plate-shaped silencer 30 can change its angle with the airflow by rotating or translating, achieving continuous linear adjustment of the airflow and making it easier to control the relationship between the opening and the airflow. In other embodiments, the silencer 30 has a square or rhomboid cross-section.

[0053] This embodiment also provides an air conditioning unit to solve the problem that the air volume regulating valve 12 and the silencer 11 cannot be used together when the overall structure of the air conditioning unit is relatively compact.

[0054] Specifically, such as Figure 6 As shown, an air conditioning unit includes a housing 50 and the aforementioned silencer valve 13. The housing 50 has a blower section 51 and a silencer section 52 inside. The silencer section 52 is located downstream of the blower section 51, and the frame 21 is located inside the silencer section 52. By applying the relatively small silencer valve 13 downstream of the airflow direction of the air conditioning unit, the airflow can be guided, and the overall structure of the air conditioning unit can be made more compact. This solves the problem that the air volume regulating valve 12 and the silencer 11 cannot be used together when the overall structure of the air conditioning unit is relatively compact.

[0055] Furthermore, the housing 50 is also provided with a mixing section 53, a composite filtration section 54 and a chilled water coil section 55 in sequence along the airflow direction. The blower section 51 is located downstream of the chilled water coil section 55, and the silencer valve 13 is located at the downstream end of the airflow direction, thereby guiding the airflow out of the air conditioning unit.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
