Document Type and Number:
WIPO Patent Application WO/2018/181194
Kind Code:

Abstract:
Provided is a highly versatile exhaust system of an electric vacuum cleaner with which exhaust including fine dust expelled from the electric vacuum cleaner can be reliably exhausted to the outdoors at low cost, using a simple configuration. This exhaust system is provided with a pipe tube (2) for expelling exhaust expelled from an exhaust port of the electric vacuum cleaner to a prescribed outdoor location, wherein said pipe tube (2) includes: a tube main body made of a material that is flexible and has poor elasticity; and a cord (3) which is inserted through the inside of the tube main body and is made of a material that is flexible and highly elastic. The cord (3) has a length when not elongated that is close to an actual extension capable of joining the exhaust port of the indoor electric vacuum cleaner to the prescribed outdoor location. The tube main body has a length that is the same as the length of the cord (3) when elongated. In this state, the ventilating function of the tube main body has a maximum value.
