Silent structure and mobile air conditioner

Abstract

Disclosure is a silent structure and a mobile air conditioner and relates to the technical field of mobile air conditioners. The silent structure includes a connecting cylinder, a soundproof chamber, and a sealing cover; an accommodation space is formed inside the connecting cylinder, and one end of the connecting cylinder is arranged on a mounting chassis of the mobile air conditioner; another end of the connecting cylinder is covered by the soundproof chamber; a soundproof space is formed inside the soundproof chamber and is connected with the accommodation space; a pipeline connecting hole is arranged on the soundproof chamber; the sealing cover is arranged on the pipeline connecting hole. Disclosure solves the problem that the noise reduction effect of the mobile air conditioner in the prior art is not ideal.
