Title: Blower
Inventor: UMEOKA KAZUAKI
IPC: G10K11/16
Filed: 1988-12-23
Abstract: PURPOSE:To provide a blower which has a high airflow and air pressure and reduces the generation of noise by a method wherein a flow passage is divided, and a control element formed by a double pipe and controlling the phase speed of a sound wave is disposed in at least the one of flow passages arranged in parallel to each other. CONSTITUTION:A control element 8 is disposed to a suction port 6 in a casing 1, and forms double pipe structure formed with inner and outer pipes 8a and 8b. When a sound wave passes through the control element, the inner pipe wall of the control element is resonated. A phase speed is widely changed in the vicinity of the resonance frequency. Since, when a sound wave enters the control element, a motion is effected based on an above principle, a phase is generated inside and outside the control element 8, and propagation of noise generated in a drier casing 1 to the outside is suppressed by relative interference, resulting the possibility to reduce the generation of noise leaking from the interior of the casing to the outside.
