Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner silencing, in particular to a detachable air conditioner muffler. Background Art

[0002] A muffler is a device that blocks the propagation of sound but allows air to pass through. It is an important measure to eliminate aerodynamic noise. It can reduce noise to a certain decibel value. A better muffler equipment can reduce noise to about 40 decibels, thereby significantly reducing the noise pollution of the air-conditioning system. The muffler uses the principles of sound absorption, reflection, and interference to reduce noise.

[0003] The air conditioner silencer disclosed in the existing patent announcement number CN212720238U includes a silencer hole and a silencer baffle assembly. There are a large number of fine pores inside the porous material, and the pores are connected to each other. When the sound wave is incident on the surface of the material, a part of it is reflected on the surface of the stainless steel plate, and the other part penetrates into the interior of the stainless steel plate, causing the air in the pores to vibrate. Due to friction and the viscous resistance of the air, the sound energy is converted into heat energy and dissipated; at the same time, the heat loss caused by heat conduction between the air in the small hole and the hole wall also causes the sound energy to attenuate; in addition, after the sound wave is reflected on the rigid wall surface, when it passes through the stainless steel plate and returns to its surface, a part of it is incident on the interior of the stainless steel plate again, and the sound is absorbed and noise is reduced through the resistive effect of the resistive baffle.

[0004] When installing the above device, it is necessary to punch holes in the muffler pipe to facilitate the installation of the muffler pipe. During long-term use, it needs to be maintained and replaced to ensure the muffler effect. After disassembly, the threaded holes at the installation site may be damaged due to repeated rotation of the bolts, and punching holes again will cause damage to the surrounding area of ​​the installation site. In view of the above problems, a detachable air conditioner muffler is proposed. Utility Model Content
