ACOUSTIC DUCT FOR AIRCLEANER

摘要

PURPOSE: An acoustic duct for an air cleaner is provided to enable the shape of a suction pipe to be maintained as established since a shape maintaining member is integrally connected to the suction pipe and the suction pipe is supported. CONSTITUTION: An acoustic duct for an air cleaner comprises a hard supply pipe(50), a suction pipe and a soft shape maintaining member. The supply pipe is directly connected to the air cleaner and supplies the external air to it. The suction pipe is connected to the supply pipe and absorbs the external air by a suction stroke at a high pressure. The suction pipe is formed as a soft sound-absorbing member and decreases the noise, which is generated by high-pressure suction force. The shape maintaining member is integrally connected to the suction pipe. The shape maintaining member shields the suction pipe and maintains the shape of the suction pipe as established. The shape maintaining member comprises a pipe type of cover(70), which has a noise hole(HL), and a fixing member.
