Silencer and air conditioner comprising same

Abstract

The invention provides a silencer and an air conditioner comprising the same. The silencer comprises a barrel body, an air inlet connecting pipe and an air outlet connecting pipe, wherein the interior of the barrel body is wholly through, a barrel body part is arranged in the middle, an air inlet and an air outlet are formed in two ends respectively, and sectional areas of the air inlet and the air outlet are smaller than the sectional area of an inner cavity of the barrel body part; the sectional area of the air inlet connecting pipe is smaller than that of the inner cavity of the barrel body part, and the air inlet connecting pipe is connected with the air inlet; the sectional area of the air outlet connecting pipe is smaller than that of the inner cavity of the barrel body part, and the air outlet connecting pipe is connected with the air outlet; and the barrel body is made of an elastic material. According to the silencer and the air conditioner comprising the same, the elastic material such as composite rubber or plastic and the like is adopted to prepare the barrel body, so that not only is the cost reduced, but also the barrel body has great elasticity and a buffer performance, and then the silencer can perform an effect of eliminating noise, and can reduce stress strain of a pipeline and pipeline vibration of the device, as well as noise caused by vibration.

Description

technical field [0001] The invention relates to the technical field of noise control, in particular to a muffler and an air conditioner including the muffler. Background technique [0002] The stress, strain and vibration noise of pipelines in fluid power equipment, especially in air conditioners, have become a major problem in product development. In order to solve the above problems, silencers are often installed in the device to reduce the stress, strain and vibration of pipelines noise. [0003] At present, there are two types of air-conditioning mufflers on the market: all-copper mufflers and copper-steel mufflers. Among them, the whole copper muffler is made of copper as a whole. Due to the high price of copper, the cost of the muffler with this structure is relatively high; the material used in the middle part of the copper-steel muffler is steel, and the two ends are connected The pipe part is made of copper, and all parts are connected together by welding. The mid...
