发明名称 Vacuum cleaner
摘要 A vacuum cleaner having a discharge flow path, which reduces noise generated due to resistance of the flow path, and by a motor. The vacuum cleaner includes a body, a blower fan unit including a blower fan and a motor to generate suction force in the body, an inner case surrounding the blower fan unit and having an inner flow path formed therein, an outer case surrounding the inner case, and a discharge flow path formed between the inner case and the outer case to communicate with the inner flow path. The discharge flow path including a circulation flow path branched from the inner flow path to guide air discharged from the blower fan unit, and a bent flow path branched from the inner flow path to guide the air discharged from the blower fan unit, the air is thereby bent a number of times in the bent flow path.
