Description

Technical Field

[0001] This utility model relates to the field of air conditioner muffler installation technology, specifically to a nested multi-stage air conditioner muffler. Background Technology

[0002] During air conditioner operation, the compressor works intermittently and periodically, which causes the refrigerant pressure and speed in the piping system to exhibit a pulsed pattern. This pulsed pattern can cause noise transmission problems in the indoor unit of the air conditioner, affecting the user experience.

[0003] Resistive silencers: These silencers utilize the sound-absorbing properties of sound-absorbing materials to reduce noise. The sound-absorbing material is fixed inside the cavity of a swirling airflow pipe, or arranged in a specific way within the pipe or outer casing. The porous structure and looseness of the sound-absorbing material allow ultrasonic waves to enter the pores, causing minute vibrations in the gas and material within the pores. Through friction and viscous resistance, the sound is converted into heat energy and absorbed.

[0004] The existing resistive mufflers are often connected to the sound-absorbing structure and the sound-absorbing equipment by bolts or rotation. However, when replacing the sound-absorbing equipment, the muffler itself is in a relatively confined space, so the entire muffler needs to be removed before the sound-absorbing structure can be replaced. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments. Example

[0018] Reference Figure 1-6 This first embodiment of the present invention discloses a nested multi-stage air conditioner muffler, comprising: a muffler housing 1 and sound-absorbing devices 2. Several sound-absorbing devices 2 are arranged in an array inside the muffler housing 1. Each sound-absorbing device 2 includes: a rectangular connecting plate 3. An arc-shaped connecting plate 4 is fixedly connected to the vertical surfaces of opposite rectangular connecting plates 3. An arc-shaped housing 5 is fixedly installed on the upper surface of the arc-shaped connecting plate 4. A pair of sound-absorbing structures 6 are installed on the pair of rectangular connecting plates 3. An arc-shaped groove is formed on the upper surface of the arc-shaped housing 5. A pair of symmetrical rectangular moving grooves 7 are formed on the bottom surface inside the arc-shaped groove. A rectangular moving plate is arranged inside each pair of rectangular moving grooves 7. A ball bearing is embedded on the lower surface of the rectangular moving plate. A rectangular moving block 8 is fixedly connected to the upper surface of each pair of rectangular moving plates.

[0019] A pair of limiting rods 9 are fixedly installed on the vertical surface of each pair of rectangular moving blocks 8. An L-shaped tie rod is also installed on the vertical surface of the rectangular moving blocks 8. A moving groove 10 is also opened at the intersection of the L-shaped tie rod and the arc-shaped outer shell 5. A rubber layer is installed on the bottom surface and the top surface of the moving groove 10.

[0020] The sound-absorbing structure 6 includes: a U-shaped base plate, a pair of rectangular lifting grooves 11 are provided on the vertical surface of the U-shaped base plate, and a limiting structure 12 is provided inside the rectangular lifting grooves 11. The limiting structure 12 includes: a rectangular mounting block 13 and an arc-shaped mounting sleeve 14. A pair of mating holes are provided on the vertical surface of the rectangular lifting grooves 11.

[0021] A pair of mating holes are slidably connected to the same rectangular mounting block 13. There are mating strips on the vertical surfaces on both sides of the rectangular mounting block 13. An arc-shaped mounting sleeve 14 is provided on the lower surface of the rectangular mounting block 13. A pair of symmetrical plug-in blocks 15 are provided on the bottom surface inside the arc-shaped mounting sleeve 14. A cylindrical guide rod 16 slides through the upper surface of the rectangular mounting block 13. The rectangular mounting block 13 and the arc-shaped mounting sleeve 14 are only in contact.

[0022] The cylindrical guide rod 16 is fixedly connected to the arc-shaped mounting sleeve 14 through a pair of plug-in blocks 15. An L-shaped rod 17 is fixedly connected to the lower surface of the arc-shaped mounting sleeve 14. A memory spring 18 is provided on the upper surface of the rectangular mounting block 13. A rectangular piece is fixedly connected to the upper surface of the cylindrical guide rod 16. The rectangular piece is slidably connected to the concave frame. An inclined limiting rod 19 is fixedly connected to the top surface of the concave frame.

[0023] When installing the device, first align one side of the rectangular lifting groove 11 on the U-shaped base plate with the installation notch left between the arc-shaped connecting plate 4 and the arc-shaped outer shell 5, and then push it in. Because a memory spring 18 is provided on the upper surface of the rectangular mounting block 13, and a rectangular piece is fixedly connected to the upper surface of the cylindrical guide rod 16, the rectangular piece is slidably connected to the concave frame, and an inclined limiting rod 19 is fixedly connected to the top surface of the concave frame, when the inclined limiting rod 19 contacts the limiting rod 9, the thrust generated by the movement will cause the inclined limiting rod 19 to retract, so the arc-shaped mounting sleeve 14 fixedly connected to the cylindrical guide rod 16 will also descend. After the inclined limiting rod 19 passes through the limiting rod 9, the inclined limiting rod 19 will spring back, thereby achieving temporary fixation of the sound-absorbing structure 6. Example

[0024] Reference Figure 2 and 7 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: U-shaped sleeves 20 are fixedly installed on the arc surfaces on both sides of the U-shaped base plate, and mounting rings 21 are fixedly connected to the bottom surface of the inner side of the U-shaped sleeves 20. Arc-shaped storage sleeves 22 are inserted into the inner ring of the mounting rings 21, and arc-shaped rods 23 are slidably connected to the inner ring of the arc-shaped storage sleeves 22.

[0025] Before using the operation of Example 1, first grasp the arc-shaped storage sleeve 22 with your hand, and then follow the operation steps of Example 1. When it is necessary to disassemble the sound-absorbing structure, the pair of L-shaped pull rods can be moved relative to each other. This is because the interior of the pair of rectangular moving slots 7 is provided with rectangular moving plates, the lower surface of the rectangular moving plates is inlaid with ball bearings, the upper surface of the pair of rectangular moving plates is fixedly connected with rectangular moving blocks 8, the vertical surface of the pair of rectangular moving blocks 8 is fixedly provided with a pair of limiting rods 9, and the vertical surface of the rectangular moving blocks 8 is also provided with L-shaped pull rods.

[0026] Therefore, after the pair of rectangular moving blocks 8 have moved, the limiting rod 9 will be inside the arc-shaped outer shell 5. At this time, simply grab the arc-shaped storage sleeve 22 and pull out the sound-absorbing structure 6.

[0027] The remaining structure is the same as that in Example 1.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
