Embodiment Construction

[0030] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0031] Such as figure 1 with figure 2 As shown, the muffler of this embodiment includes: a muffler structure. The sound-absorbing structure includes: a sound-absorbing support body 12 , a sound-absorbing outer layer 11 and a sound-absorbing inner core layer 13 . The sound-absorbing outer layer 11 is wrapped around the circumferential outer side of the sound-absorbing support body 12 . The sound-absorbing inner core layer 13 is sandwiched inside the sound-absorbing support body 12 .

[0032] Applying the technical solution of this embodiment, the muffler is fixed in the air duct 100. After the sound waves enter the muffler, the sound waves cancel each other to achieve the purpose of muffled...

Abstract

The invention provides a silencer and an air conditioner. The silencer comprises a silencing structure. The silencing structure comprises a sound absorption supporting body (12), a sound absorption outer layer (11) and a sound absorption inner core layer (13), wherein the circumferential outer side of the sound absorption supporting body (12) is wrapped with the sound absorption outer layer (11), and the sound absorption inner core layer (13) is clamped in the sound absorption supporting body (12). By the adoption of the technical scheme, the problem that the resistance of a silencer in the prior art is quite high is effectively solved.

Description

technical field [0001] The invention relates to the technical field of noise reduction, in particular to a muffler and an air conditioner. Background technique [0002] At present, the chip mufflers used in the combined cabinets are all combined with side-opening metal plates and glass wool. The combination of perforated metal plate and attracting material will result in poor flow field performance and high resistance. Contents of the invention [0003] The main purpose of the present invention is to provide a muffler and an air conditioner to solve the problem of high resistance of the muffler in the prior art. [0004] In order to achieve the above object, according to one aspect of the present invention, a muffler is provided, including: a sound-absorbing structure, the sound-absorbing structure includes: a sound-absorbing support body; a sound-absorbing outer layer wrapped around the circumferential outer side of the sound-absorbing support body; The sound-absorbing ...
