Abstract

PURPOSE:To change airflow, discharged out of an air filter, into laminar flow and prevent the stagnation of dust in a clean room by a method wherein the flow path of the airflow, sent out of a fan, is lengthened and the airflow is introduced into the air filter by guiding it by an airflow guiding equipment. CONSTITUTION:The inside of a casing 1 is divided into two chambers of a fan chamber 11 at the inflow side of airflow and a filter chamber 12 at the discharging side of the airflow. The dynamic pressure of rotary airflow, sent out of the delivery port 21 of a fan 2, is not uniform since the speed of the airflow at the inner side of the fan chamber 11 is slow and the same at the outer side thereof is high. However, the dynamic pressure thereof is averaged during the airflow is circulated through about 1/4 circumference of the fan chamber 11 while the dynamic pressure is uniformized further during passing through a reticulated guide vane 51 positioned at the inside of the airflow guiding equipment 5. At the same time, the flow of air is regulated and is guided by an outside guide vane 52 to introduce it into the filter chamber 12. The introduced airflow is cleaned by passing through an air filter 3 and becomes laminar flow, thereafter, is discharged to the outside of the casing 1.

The air purifying device having such a configuration uses the fan 2 to suck air into the fan 2 along its axial direction, and the fan 2 sucks air into the fan 2 from its outlet 21 along a plane perpendicular to the suction direction. Airflow is sent into the fan chamber 11. The airflow sent out from the outlet 21 of the fan 2 travels approximately 1/4 of the way around the inside of the fan chamber 11 along the side surface of the casing 1, and connects to the communication port 13 other than the portion blocked by the shielding plate 6 and the fan chamber 11. The air is introduced into the communication port 13 through the communication portion of the air flow guiding device 5 , passes through the mesh-like guide vane 51 inside the airflow guiding device 5 , is guided to the outside guide vane 52 , and is introduced into the filter chamber 12 .

Since the inside of the fan chamber 11 is slow and the outside is fast, the dynamic pressure of the airflow is non-uniform. The dynamic pressure of the airflow having such non-uniform dynamic pressure is averaged while it travels approximately 1/4 of the way around the fan chamber 11. Then, while the airflow whose dynamic pressure has been averaged passes through the net-shaped guide vane 51 located inside the airflow guide device 5, the dynamic pressure is further made uniform and the airflow is rectified.
