专利汇可以提供Vacuum cleaner专利检索,专利查询,专利分析的服务。并且PURPOSE: To substantially reduce noise by a method wherein an exhaust port of a cleaner main body is directed toward the inside of a case so as to use the case itself as a silencer.
CONSTITUTION: A lower case 7 is provided with a flange 7a around the upper edge to support a cleaner main body 1. An exhaust port 6 is directed toward the lower case 7, and an opening 7d and a hose hole 7e through which a suction hose 2 is inserted are provided on a case wall other than a case wall 7b which is close to the exhaust port. Thereby, as the exhaust port of the cleanser main body is directed toward the inside of the case, noise caused by driving of a motor and air suction of a fan and dispersed from the exhaust port is prevented from being directly discharged outside. And, as the opening is provided on the case wall apart from the exhaust port, the case itself functions as a silencer, and as exhaust air is discharged outside after passing through the lower case as a silencer, noise can be substantially reduces.
